This research is the development model of household welfare coastal fishing in the Riau Islands province in utilizing the potential of the maritime resources in the coastal province of Riau Islands. The population of the research was the fishing households in the coastal province of Riau Islands as much as 398 samples. Testing research of generalization done by using Least Square Estimation (GLS) model, the analysis of Structural Equation Models (SEM) with proportionate sampling method and use AIDS AMOS 21 consisting of: 5 variables, 21 63 indicators and instruments. Test results showed the model fit the resulting value of the chi square 183.813, significance probability 0057, GFI, AGFI 0.956 0.934, TLI 0.940, CFI 0.956, RMSEA 0.022, CMIN/DF 1.186 are all in the range of expected value so that the model can be accepted. The results showed that: (1) maritime coastal resource potential significant effect against the policy of the local government; (2) maritime coastal resource potential influential significantly to community empowerment; (3) the potential resources of the coastal maritime effect is not significantly to household economic behavior of coastal fishing; (4) community empowerment not significant effect against the economic behaviour of households coastal fishing; (5) the policy of local government economic behavior significantly to the influential households coastal fishing; (6) household economic behavior of coastal fishing effect significantly to public welfare_RTNP; (7) the local government policy take effect is not significantly to public welfare_RTNP; (8) community empowerment effect is not significantly to public welfare_RTNP; (9) maritime coastal resource potential effect is not significantly to public welfare_RTNP. Based on those results showed that the potential resources of the coastal maritime province Kepri can support the household well-being of fishermen on the coast, but has not yet been optimally utilized and not to increase well-being. Model development of household well-being coastal fishing can be used as an alternative in utilizing and managing maritime resource potential in the coastal province of Riau Islands province by improving several indicators to support relationship variable. The name of model of the development of household well-being coastal fishing is called ERDOGANA based management resource potential and utilization of maritime coast.


In Education (as in many other fields) it is common to create complex systems to assess the state of latent properties of individuals — the knowledge, skills, and abilities of the students. Such systems usually consist of several processes including (1) a context determination process which identifies (or creates) tasks—contexts in which evidence can be gathered,—(2) an evidence capture process which records the work product produced by the student interacting with the task, (3) an evidence identification process which captures observable outcome variables believed to have evidentiary value, and (4) an evidence accumulation system which integrates evidence across multiple tasks (contexts), which often can be implemented using a Bayesian network. In such systems, flaws may be present in the conceptualization, identification of requirements or implementation of any one of the processes. In later stages of development, bugs are usually associated with a particular task. Tasks which have exceptionally high or unexpectedly low information associated with their observable variables may be problematic and merit further investigation. This paper identifies individuals with unexpectedly high or low scores and uses weight-of-evidence balance sheets to identify problematic tasks for follow-up. We illustrate these techniques with work on the game Newton's Playground: an educational game designed to assess a student's understanding of qualitative physics.


The novel DC-DC converter composed of multi-cell diode-capacitor network provides a simple solution for high step-up power conversion in renewable energy applications. With regard to the uni-directional power flow of the diodes, multi-capacitors are naturally charged in parallel, and discharged in series. Thus, high voltage gain is achieved without extreme large duty ratio of power devices. Furthermore, it does not increase the complexity of control circuit due to only one fully controllable power device. However, a lot of passive components increase the order of system model and complexity. This paper proposes a new modeling approach to get the reduced model for high voltage gain DC-DC converter with multi-cell diode-capacitor network. Then, the linear closed-loop controller is designed based on the reduced model in frequency domain. Finally, simulation and experiment are implemented to verify the correctness and effectiveness of the reduced-order modeling approach. And it contributes to the simplification of controller system, which is very promising in high voltage gain DC-DC converter with multi-cell diode-capacitor/inductor network in the renewable energy application.


Along with the perfection of taxation system, the country enhances the supervision of in- dividual income tax constantly. It is easy for managers of the scientific research funds to ignore the tax man- agement of scientific research work reward. Combined with the actual work, this article pointed out the tax misunderstanding of the scientific research work reward that exists in scientific research funds management, and analyzed some examples that explain the difference and methods of calculating the individual income tax by the scientific research work reward in the different situations. Moreover, it clarified that it is very impor- tant for the management of scientific research funds to tax the individual income according to law.

Key words:
Scientific research work pay;  Individual income tax;  Ratepaying mistake;  Fi- nancial management


The presentation focuses on a school experiment with an experimental sensual perception exercise. A first test was carried out in an art course and later reproduced in parts with colleagues in Dresden. The theoretical background, realisation, results and conclusions are outlined. Starting from the assumption that education and learning are always initiated by individual questions, problems and aims, the project seeks ways of enabling advanced school students to find and develop their own assignments and goals in art courses. The explanations regarding the initiation and aims of the project also consider and include the general framework of art didactics, sensual perceptions, and teaching and learning in the future, as well as the relationships between art and science.

The object of the present study was to quantify the concentration of protein, carbohydrate and lipid in the hepatopancreas and muscle of Fenneropenaeus merguiensis and F. penicillatus during the moulting stages, post moult (stages A and B), intermoult (stage C) and premoult (stage D). The protein concentrations in the hepatopancreas showed significant differences between males and females of F. merguiensis. However, the lipid and carbohydrate were not significantly different between the two sexes in this species. The protein, carbohydrate and lipid concentrations in the hepatopancreas of F. penicillatus were significantly different in two sexes. The protein and carbohydrate concentrations in the muscles of males and females F. penicillatus were significantly different but in F. merguiensis these concentrations were not significantly different. The lipid concentrations were different between two sexes in both species. The protein and carbohydrate concentrations in hepatopancreas of F. merguiensis and F. penicillatus were either of same order or slightly different during stages B and C, but significantly higher during molting stage D. The lipid concentrations in the hepatopancreas of these two species varied during the three molting stages, being lowest during stage B and highest during stage D. In two species, the protein, carbohydrate and lipid concentrations in the muscles were almost similar during moult stages B and C but higher in stage D.


This research investigates the privacy, confidentiality and integrity of data over the Cloud. It explores different data security concerns over the Cloud as perceived by experts and university students. This topic is significant because of the increasing demand for Cloud services that attracts many people to use it more frequently. Being aware of data security concerns will undoubtedly help users take precautions from unauthorized access up to data theft. The comparison between the views of experts and users of data threats over the Cloud encourages investigators to conduct further research to increase awareness and maximize security measures. This study is based on the assumption that data over the Cloud are secure. This paper reviews the literature that focuses on the experts' findings and interpretations of data security issues and threats over the Cloud. The Cloud Security Alliance (CSA) [I] points out seven security threats: abuse and nefarious use of Cloud Computing, insecure Application Programming Interfaces (APIs), malicious insiders, shared technology vulnerabilities, data loss or leakage, account or service hijacking, and unknown risk profile. In addition, experts state different attacks that may occur at any time: DoS attacks, Cloud malware injection, side channels attack, authentication attacks, and Man-In-The-Middle (MITM) cryptographic attack. In this study, completed questionnaires were collected from students of the University of the West of England to examine their perception and awareness of data threats over the Cloud. Both perceptions from experts and students were compared and analyzed to derive conclusions about data security over the Cloud. A number of findings are discovered. As experts prove that data might be compromised over the Cloud, the outcome of this research reveals that users are unaware of these threats. Many users are unaware of the issues they face concerning their data's privacy, confidentiality, and integrity. However, the participants value their data privacy. The results also show that they utilize the Cloud for different purposes and various benefits. As for further research, many ideas are proposed with regard to research settings in terms of size of sample, type and background of population, and the choice of qualitative methodology.


The compressional and shear wave velocities in a multicomponent alloy, Wood's metal, were accurately determined by the pulse transmission method at temperatures between room temperature and 100°C. The melting point of Wood's metal was found to be 71.4°C, and the rates of temperature change upon heating and cooling were 1.887–0.063°C/min and 0.830–0.049°C/min, respectively. A large hysteresis loop in the relation between the sound velocity and temperature were observed around the melting point. The hysteresis depended strongly on the degree of supercooling, which was in turn affected by the rate of temperature change. The significance of the hysteresis loop in the melting-solidifying process is discussed by combining the present ultrasonic data with observations of the metal texture by metal-reflecting microscope.


Background— Radiofrequency catheter ablation of atrial fibrillation (AF) guided by complex fractionated atrial electrograms has been reported to eliminate AF in a large proportion of patients. However, only a small number of patients with chronic AF have been included in previous studies. Methods and Results— In 100 patients (mean age, 57±11 years) with chronic AF, radiofrequency ablation was performed to target complex fractionated atrial electrograms at the pulmonary vein ostial and antral areas, various regions of the left atrium, and the coronary sinus until AF terminated or all identified complex fractionated atrial electrograms were eliminated. Ablation sites consisted of ≥1 pulmonary vein in 46% of patients; the left atrial septum, roof, or anterior wall in all; and the coronary sinus in 55%. During 14±7 months of follow-up after a single ablation procedure, 33% of patients were in sinus rhythm without antiarrhythmic drugs, 38% had AF, 17% had both AF and atrial flutter, 9% had persistent atrial flutter, and 3% had paroxysmal AF on antiarrhythmic drugs. A second ablation procedure was performed in 44% of patients. Pulmonary vein tachycardia was found in all patients in both previously targeted and nontargeted pulmonary veins. There were multiple macroreentrant circuits in the majority of patients with atrial flutter. At 13±7 months after the last ablation procedure, 57% of patients were in sinus rhythm without antiarrhythmic drugs, 32% had persistent AF, 6% had paroxysmal AF, and 5% had atrial flutter. Conclusions— Modest short-term efficacy is achievable with radiofrequency ablation of chronic AF guided by complex fractionated atrial electrograms, but only after a second ablation procedure in >40% of patients. Rapid activity in the pulmonary veins and multiple macroreentrant circuits are common mechanisms of recurrent atrial arrhythmias.


A simple preparative method has been employed for the synthesis of the novel cluster compound Ga9 (CMe3 )9 , which contains a tricapped trigonal prism of monovalent gallium atoms. Electron transfer processes were observed similar to those of polyboranes, leading to the the reversible formation of the corresponding radical anion.


The mechanical properties of fiber-reinforced cementitious matrix (FRCM) composites are derived from tensile tests of composite coupons and shear tests of composite strips bonded to the substrate. Different test set-ups are used for tensile coupons, which lead to different tensile responses depending on the mechanical properties of the matrix and bond properties of the fiber-matrix interface. Direct shear tests are employed to study the stress-transfer between the composite and the substrate onto which the composite is bonded. These tests can be employed to obtain the cohesive material law (CML) that describes the bond behavior at various interfaces, such as the matrix-substrate, matrix-matrix, and fiber-matrix interface. In this paper, the cohesive material law associated with the fiber-matrix interface of a polyparaphenylene benzo-bisoxazole (PBO) FRCM composite is employed in an analytical model to reproduce the tensile response of the FRCM composite, when the fibers are gripped directly. The results of the model are compared with corresponding experimental results of tensile tests of the same FRCM composite employed to calibrate the CML. The experimental work includes digital image correlation (DIC) analysis of the cracking process. A comparison between the analytical and the experimental results is performed in terms of load response focusing on the coupon deformation and opening of the cracks.


Abstract Novel hydroxyester disiloxanes (1,3-bis(6-hydroxyhexanoylmethyl)-1,1,3,3-tetramethyl disiloxane and 3-bis(2-hydroxypropanoylmethyl)tetramethyl disiloxane) were synthesized, and preparation of other known monomers, namely 1,3-bis(hydroxypropyl)-1,1,3,3-tetramethyl disiloxane, 1,3-bis(hydroxyethoxypropyl)-1,1,3,3-tetramethyl disiloxane and 1,3-bis(hydroxymethyl)-1,1,3,3-tetramethyl disiloxane was developed to obtain better yields and reduce production time and expense. All compounds were characterized by infrared spectroscopy, using 1H NMR, 13C NMR, and 29Si NMR and were reacted with diisocyanates, resulting in poly(siloxane-urethane) copolymers with unique properties.


Onshore wind energy development is often delayed or even prevented by local resistance. Against this backdrop, we discuss financial participation as a measure to promote local acceptance by positively influencing the perceived experience of justice. Building on the concept of energy justice, this paper investigates the extent to which different forms of financial participation are suitable for better distributing costs and benefits, creating opportunities for participation, and examining who can participate financially. In addition to a comprehensive literature review, interviews were conducted with wind turbine planners and operators. These show that stakeholders engage in financial participation to different degrees across different projects and that the preferred form of participation varies from one region to another. Moreover, no model of financial participation appears to be suited to address all dimensions of energy justice, as all models are characterised by certain advantages and disadvantages. Therefore, the availability of financial participation options alone is unlikely to increase local acceptance. Such options can, however, be effective when combined with other measures to increase acceptance.


In any account of the legal system in the Sudan, two points must be made clear at the outset: (1) Where references are made to the Islamic Shanta law, it should be understood that this reference is to the Hanafi school of law) for it is that school which is applied by the Shari'a Court Division of Personal Status in the Sudan. Most of the doctrines relating to civil transactions in the Sudan, whether incorporated in the Civil Law 1971 or the Law of Civil Transactions 1984,2 stem from the Hanafi school of law which was introduced. Interestingly enough, howe^7er, the majority of Sudanese belong to the Maliki school which prevails in certain religious affairs.3 The co-existence of these two systems resulted from historical circumstances: the Hanafi law had been previously codified in the nineteenth-century Ottoman Majalla which had applied throughout the Turkish Empire for many years except principally, in Egypt and the Sudan. (2) The Sudan Law of Contract 1974 was principally a codification of the Common law doctrines and principles as applied in the Condominium period and thereafter until 1971. Thus, English law will be referred to as the origin of the Law of Contract 1974, and its voluminous body of precedents will be relied upon to compare the doctrines of freedom, sanctity and frustration of contracts.


We must analyses institutional reasons for the low growth of chinese non-state-own enterprise with the method of property rights and the path analysis, and then we can find new path of institutional innovation for non-state-own enterprise. Low or none growth of many enterprises shows the existence of great institutional barrier. Efficient enterprise institutions should advantage the enterprise growth because owners and managers can be effectively encouraged to be corcerned about enterprises' growth by sharing the enterprise' property rights and structure of governance.


Article history: Received 08th Feb. 2020 Accepted 17th May 2020 Available online 30th June 2020 The textile-reinforced concrete composite material (TRC) consists of a mortar/concrete matrix and reinforced by multi-axial textiles (carbon fiber, glass fiber, basalt fiber, etc.). This material has been used widely and increasingly to reinforce and/or strengthen the structural elements of old civil engineering structures thanks to its advantages. This paper presents a numerical approach at the mesoscale for the mechanical behavior of TRC composite under tensile loading. A 2-D finite element model was constructed in ANSYS MECHANICAL software by using the codes. The experimental results on basalt TRC composite from the literature were used as input data in the numerical model. As numerical results, the basalt TRC provides a strain-hardening behavior with three phases, depending on the number of basalt textile layers. In comparison with the experimental results, it could be found an interesting agreement between both results. A parametric study shows the significant influence of the reinforcement ratio on the ultimate strength of the TRC composite. The successful finite element modeling of TRC specimens provides an economical and alternative solution to expensive experimental investigations.


Sinonasal non‐keratinizing squamous cell carcinoma (SCC), previously designated as transitional cell carcinoma or cylindrical cell carcinoma, is an uncommon malignant neoplasm with distinct histopathological features, considered to be a low‐grade malignancy that usually occurs in elderly patients. Extensive local invasion is uncommon. Here we report a case of 90‐year‐old woman whose original presentation was as erythematous nasal skin nodules, biopsy of which showed a dermal tumor with features of sinonasal non‐keratinizing SCC. No epidermal dysplasia was present. A subsequent computed tomography scan confirmed the presence of an endophytic tumor on the nasal sidewall. The initial presentation of sinonasal non‐keratinizing SCC as a skin lesion is previously unreported to our knowledge. Diagnosis in this context requires accurate evaluation of the histopathology as well as a comprehensive knowledge of pathology specific to this anatomic location.

Deep neural networks have been successfully applied to many real-world applications. However, these successes rely heavily on large amounts of labeled data, which is expensive to obtain. Recently, Auto-Encoding Transformation (AET) and MixMatch have been proposed and achieved state-of-the-art results for unsupervised and semi-supervised learning, respectively. In this study, we train an Ensemble of Auto-Encoding Transformations (EnAET) to learn from both labeled and unlabeled data based on the embedded representations by decoding both spatial and non-spatial transformations. This distinguishes EnAET from conventional semi-supervised methods that focus on improving prediction consistency and confidence by different models on both unlabeled and labeled examples. In contrast, we propose to explore the role of self-supervised representations in semi-supervised learning under a rich family of transformations. Experiment results on CIFAR-10, CIFAR-100, SVHN and STL10 demonstrate that the proposed EnAET outperforms the state-of-the-art semi-supervised methods by significant margins. In particular, we apply the proposed method to extremely challenging scenarios with only 10 images per class, and show that EnAET can achieve an error rate of 9.35% on CIFAR-10 and 16.92% on SVHN. In addition, EnAET achieves the best result when compared with fully supervised learning using all labeled data with the same network architecture. The performance on CIFAR-10, CIFAR-100 and SVHN with a smaller network is even more competitive than the state-of-the-art of supervised learning methods based on a larger network. We also set a new performance record with an error rate of 1.99% on CIFAR-10 and 4.52% on STL10. The code and experiment records are released at this https URL.


This research was aimed to analyze student's behavior and dominant factors in the buying decision for halal food product. The research was conducted by survey method using quisioner to 100 responden. The data were analyzed using descriptive analysis and factor analysis using a Kaiser Meyer Olkin (KMO) method and principal component analysis. The research showed stages in decisions process to purchase of halal food product were need assesment (hunger 30% and life style 30%), information retrieval (directly see 41% and meeting religion 19,9%), alternative evaluation (looking the expiration date 34% and not consume food comes from pork 29%), the purchase decision (always see halal label 85% and not so buy without halal label 51%) and post purchase of food product halal (uncertain eat at canteen college 54% and need to be given a halal certificate any campus canteen 93%). The result of factor analysis showed that there were four factors which affecting the decision. These factors were product's attributes (product label, making process ingredient and production date); internal factor (income, motivation and lifestyle); religion/culture (halal label and certificate) and the external factor (seller, place and price) Keyword : behavior, halal food, purchasing and student


This note reports an innovative state-of-the-art empirical analysis of Job Creation in the European Union in the same vein as the classical studies in the United States. It is based on an exceptionally large sample of firm-level employment data in the period 2004-2015 obtained from Orbis, a databank published by Moody's Bureau van Dijk. Consistently with our representiveness assessment, the final sample consists of firms registered in 20 out of the 28 EU Member States. The study follows the empirical literature and defines three indicators which may be equally plausible policy objectives. The job creation [destruction] is the total number of jobs created [destroyed] by growing [shrinking] firms and reflects the job turnover of a market and its capacity to enhance the labour market dynamism. The net job creation is the difference between job creation and job destruction and captures the employment growth. The net job creation rate is the employment growth rate and reflects the capacity of firms of being efficient in creating new jobs. The main findings are as follows: — The young-SME category is the largest contributor to net job creation (employment growth). Moreover, its contribution to job creation amounts to 40 percent which is far larger than its share in employment amounting to 15 percent. — The share of start-up firms in employment varies between 2 and 9 percent across countries with new Member States typically exhibiting larger shares. Even though to various degrees, nearly all Member States have experienced a decline of start-ups measured as the share of employment. — With nearly 60%, high-growth firms (HGF) exhibit the largest incidence on total job creation. Even though the young HGFs are more numerous, mature HGFs contribute to job creation to a larger extent. — Firms borrowing for the first time report net job creation rates of about 8 percent higher in the next three years, on average. Besides, the net job creation rates of firms with bank loans are less sensitive to economic cycles. The results yield a number of policy implications. In particular, they provide empirical support to policies aimed at encouraging young firms and entrepreneurship in Europe. They also show that job creation of SME may face obstacles in their "scaling-up" development phase. Last, the impact of external financing on net job creation rates may vary among Member States – especially through the business cycles. These results deserve further investigation. By providing a large-scale investigation of job creation in Europe and providing related policy tools, the report aims to contribute to the European Commission's first priority, "to boost jobs, growth and investment."


The author reviewed his data from 2012 through 2019 and focused on both of his metabolic conditions and health lifestyle details.  He then developed an "Effective Health Age" model by using the GH-Method: math-physical medicine approach in comparison with the "Real Biological Age".  He defined Effective Health Age  based on the evaluation of his multiple medical examination reports and his ~2 million data of his lifestyle, metabolism, and diseases over an 8-year period.  This is different from the "Real Biological Age" or "Chronological Age" defined as the actual amount of time a person has been alive.  In 2014, the author developed a mathematical metabolic model, including 4-categories of diseases (body outputs) and 6-categories of lifestyle details (body inputs).  He started to collect his data of weight and glucose beginning on 1/1/2012 and other lifestyle data from 2013-2014.  He further assembled those 10-categories (with a total of ~500 detailed elements) and combined them into two new biomedical terms: the metabolism index (MI), which is a combined daily score to show the body health situation, and general health status unit (GHSU), which is the 90-days moving average number to show the health trend.  He further developed a simple equation to calculate his effective health age as follows:

 Effective Health Age= Real Biological Age *

(1+((MI-0.735)/0.735)/2)

He then utilized his annualized MI data to calculate his effective health age in order to compare against his real biological age. (Up to 250 words)


Capturing and representing information systems requirements using quality artifacts is an important step in successful implementation. Better quality artifacts in the early stages of systems development help in early detection and correction of errors. Although UML is widely used for modeling systems requirements, it is often difficult for novice systems analysts to develop quality UML artifacts. This paper presents an application of the conceptual model quality framework proposed by Lindland et al (1994) for identifying quality dependencies among the UML artifacts developed by novice systems analysts in an undergraduate course on object-oriented systems analysis and design. Findings from this study offer directions for enhancing teaching and learning of systems analysis techniques with UML.


Voxel phantom,associated with Monte Carlo simulation methods,has been applied in researches of radiation protection.But the simulation is time consuming which limits the wide application of voxel phantom.This work studied the description of voxel phantom for simulation and presented a method to describe voxel phantom in MCNP(Monte Carlo N-particle) with a 3-D voxel combination algorithm.The results show that the time spent in transportation of particles decreases 32% but more time is needed to tally energy deposited in tissues or organs.

Our specific responsibility is to build the "foundation" of our internal Cybersecurity and Technology Controls. We have been using the CSF since before 1.1 was finalized, although we now implement it via the Cyber Risk Institute's Financial Sector Profile. One of the things that my Team has done has been to "build out" our implementation of the CRI Financial Sector Profile to make it a Cyber and Technology control framework [as opposed to purely cyber] on the basis of the fact that sometimes it isn't clear which framework should be applied – and the effort cost of trying to keep 2 discrete structures in lock step is significantly greater than building and maintaining an holistic framework. Happy to share details of that with you, should you be interested.


The food habits of Coluber hippocrepis nigrescens, a colubrid snake endemic to the island of Pantel leria in the southern Mediterranean Sea, were studied by means of both stomach contents and faecal analyses . Snakes preyed only on vertebrates, and most of the prey eaten were rodents (especially Rattus norvegicus). Ingested biomass per snake averaged 5 5 .63±48 .94 g (range: 8 1 3 1 g), i .e . about 28 . 5 % of the average snake mass ( 1 95 . 1 8 ±65 . 6 1 g; range: 39 -277 g). Log prey mass and log predator mass were positively correlated. The prey mass to predator mass ratio was not sign ificantly correlated with log predator mass. 3 6. 36% of the prey found in C. hippocrepis stomachs was eaten by snakes when it was already carrion, as demonstrated by the presence of abundant flesh-fly larvae in rats regurgitated by snakes. This is a very unusual foraging mode for snakes, which are known as active predators feeding on l ive organisms. We hypothesize that this unusual foraging mode is an adaptive strategy depending on ( I ) low level of food avai lab i l i ty and (2) h igh abundance of dead prey, on this arid Mediterranean i sland.


This is an extension of our recent research into the well-being consequences of life in the workplace. We place special attention here to the effects of different forms of labour relations, especially on the role of unions, and of gender differences. This ties closely to Paul Weiler's long standing research and policy interests in labour relations issues in both Canada and the United States (especially as summarized in Weiler 2000).


The affinities and distribution of Austrosimulium Tonnoir are examined in relation to those of other genera in the Simuliidae, especially those represented in the Southern Hemisphere. It is concluded that Austrosimulium is not clearly derivable from or closely related to Gigantodax Enderlein but shows greater affinities with Simulium Latreille. The South American species, A. anthtacinum Bigot is distinctly separated from the Australian and New Zealand species and is doubtfully ascribable to Austrosimulium. The doubtfully disjunctive distribution, the affinities of Austrosimulium with Simulium, and the relationships between the Australian and New Zealand species-groups, suggest that the genus is of northern origin and route of entry into New Zealand, and probably into Australia also.


This contribution to economic and social history examines income inequality in Slovenia over the past 60 years. New archival sources are used to fill gaps in previous studies and are then combined to create a synthesis of the evolution of income inequality in Slovenia. The liberal market reforms of the 1960s as well as the 1990s' transition added to inequality, while the egalitarian reforms of the 1970s reduced it. An idiosyncratic mix of socialist egalitarian institutions together with militant labour and conscious design choices made during the transition explain the persistence of low inequality and the Slovenian model of a coordinat-


Recently, the transition metal-catalyzed direct arylation reactions of azoles with aryl halides have emerged as an attractive strategy for the effective construction of aromatic Csp2–Csp2 bonds. These reactions, unlike the traditional metal-catalyzed crosscoupling protocols involving the use of preformed organometallics, enable the direct elaboration of heteroaromatic cores without the pre-activation of both the coupling partners.


Everyone intimately knows that education plays an important role in socialist construction. We are of the opinion that a correct understanding of the nature and characteristics of educational investment and a probe into its multi-channel source are instrumental in bringing into even better play the role of education and its investment. In light of this, we would like to offer some superficial opinions for discussion with the readership.


The ground-water maps of the Separations Area are prepared by the Environmental Technology Section of the Defense Waste Management Division of Westinghouse Hanford Company. The Separations Area consists of the 200 East and 200 West Areas, where chemical processing activities are carried out. This set of ground-water maps consists of a water-table map of the unconfined aquifer, a depth-to-water map of the unconfined aquifer, and a potentiometric map of the uppermost confined aquifer (the Rattlesnake Ridge sedimentary interbed) in the area where West Lake, the deactivated Gable Mountain Pond, and the B Pond system are located. The Separations Area water-table map is prepared from water-level measurements made in June and December. For the December 1987 map approximately 200 wells were used for contouring the water table. The water-table mound beneath the deactivated U Pond has decreased in size since the June 1987 measurements were taken, reflecting the impact of shutting off flow to the pond in the fall of 1984. This mound has declined approximately 8 ft. since 1984. The water-table map also shows the locations of wells where the December 1987 measurements were made, and the data for these measurements are listed.


Unified scalable information have led to many appropriate advances, including von Neumann machines and SMPs. Given the current status of modular models, statisticians clearly desire the visualization of Scheme. Here, we understand how Web services can be applied to the construc- tion of SCSI disks.


The human sympathetic nervous system has an important regulatory role. In its dysfunctional hyperexcitatory state, it can lead to multiple pathologies. The renal sympathetic nerves play a significant role in these pathological states. Percutaneous renal sympathetic denervation (RSDN) allows for safe minimally invasive selective denervation of the renal sympathetic nerves. RSDN has been shown to be safe and efficacious in blood pressure reduction in earlier nonblinded SYMPLICITY HTN-1 and -2 trials. In Europe, it is approved for a select group of truly resistant severe essential hypertension. However, its real efficacy is now in doubt with the blinded SYMPLICITY HTN-3 trial that showed no significant difference in change in office and mean 24-h ambulatory systolic blood pressure between RSDN and sham-procedure arms. This review will look at the potential targets for percutaneous RSDN-heart failure, cardiac arrhythmias and kidney disease, sleep-disordered breathing and insulin resistance.


Typical magnetic skyrmion is a string of inverted magnetization within a ferromagnet, protected by a sleeve of a vortex-like spin texture, such that its cross-section carries a positive integer topological charge. Some magnets form antiskyrmions, the antiparticle strings which carry a negative topological charge instead. Here we demonstrate that topologically equivalent but purely electric antiskyrmion can exist in a ferroelectric material as well. In particular, our computer experiments reveal that the archetype ferroelectric, barium titanate, can host antiskyrmions. The polarization pattern around their cores reminds ring windings of decorative knots rather than the typical magnetic antiskyrmion texture. We show that the antiskyrmion of barium titanate has just 2-3 nm in diameter, a hexagonal cross-section, and an exotic topological charge of minus two. We deduce that formation of antiskyrmions is favored by a fortunate combination of the moderate anisotropy of the anharmonic electric susceptibility and the characteristic anisotropy of the polarization correlations in barium titanate crystals.


Melphalan Flufenamide is a peptide-drug conjugate composed of a peptide conjugated, via an aminopeptidase-targeting linkage, to the alkylating agent melphalan, with potential antineoplastic and anti-angiogenic activities. Upon administration, the highly lipophilic melphalan flufenamide penetrates cell membranes and enters cells. In aminopeptidase-positive tumor cells, melphalan flufenamide is hydrolyzed by peptidases to release the hydrophilic alkylating agent melphalan. This results in the specific release and accumulation of melphalan in aminopeptidase-positive tumor cells. Melphalan alkylates DNA at the N7 position of guanine residues and induces DNA intra- and inter-strand cross-linkages. This results in the inhibition of DNA and RNA synthesis and the induction of apoptosis, thereby inhibiting tumor cell proliferation. Peptidases are overexpressed by certain cancer cells. The administration of melphalan flufenamide allows for enhanced efficacy and reduced toxicity compared to melphalan.1,2,3


_______________________________________________________________________________________ ABSTRACT Prosopis juliflora, an invasive plant worldwide causes major threats by destructing natural ecosystem and limits provisioning of ecosystem services in the invaded areas. Attempts to manage the species and restore invaded lands have landed countries to adopt and implement different restoration options. This study tested three restoration options namely Diveting, Mulching and Seeding and their combination to assess their effectiveness in enhancing plant diversity and forage biomass. The study cleared invaded lands in Kahe Ward, Northern Tanzania and laid two blocks, each designated to address livestock pasture and conservation challenges. Experimental blocks were laid in a complete randomized design in 10mx10m plots. Data on plant species and forage biomass were collected in each 10mx10m whereby plants were identified with the support of a botanist; their number recorded, and grass samples green and dry weight determined. The Shannon–Wiener Diversity Index was used to estimate diversity of plant species and the average values in each restoration treatment. One way ANOVA showed that, diversity of native plants was higher in control (Mean±SE =1.239±0.937) than diveting (Mean±SE =1.105±0.56) and diveting-mulching (Mean±SE =0.7703±0.55). Forage biomass was higher in control (Mean±SE =65.917±10.083) than in diveting (Mean±SE =52.425±11.15), diveting-mulching (Mean±SE =42.067±8.751) and diveting-seeding-mulching (Mean±SE =57.625±10.02) implying that restoration interventions have no positive influence on forage biomass. It is recommended that, clearing the land and leave it without restoration is enough because the restoration options do not have positive influence on plant diversity and forage biomass. This study aimed at assessing the effects of restoration techniques on plant diversity and forage biomass in areas invaded by Prosopis juliflora . The results show that restoration techniques had no positive influence on plant diversity and forage biomass. The diversity of native plants differed across DIV (Mean±SE =1.105±0.56) and DIM (Mean±SE =0.7703±0.55) were low compared CON (Mean±SE =1.239±0.937). Forage biomass was low in DIV (Mean±SE =52.425±11.15), DIM (Mean±SE =42.067±8.751) and DSM (Mean±SE =57.625±10.02) compared to CON (Mean±SE =65.917±10.083) implying that restoration interventions have not been successful in enhancing forage biomass productivity . This study therefore, concludes that application of restoration interventions after mechanical removal of Prosopis juliflora does not enhance plant diversity and forage biomass in the first production cycle. Long-term monitoring is therefore required to determine production required to make the restoration options effective.

This paper describes how the containerization of trans-oceanic general cargo traffic has been one of the most important developments in the shipping industry since the rise of the iron hulled steamship. But it has not only affected deep sea shipping operations. Ports, inland transportation modes and coastal shipping have been forced to adapt. This paper reviews the current position in the United Kingdom (UK). The authors concentrate entirely on the deep sea sector where container traffic is the main form of general cargo operation. The short sea trades to Europe and the states bordering the Mediterranean, Baltic and Black seas are not discussed. Section 2 of the paper outlines the institutional and regulatory environment that applies in the UK, and an estimate of the size of the total market and the share of each mode with it is then given in sections 3 and 4. Section 5 presents evidence on the prices paid by liner operators for the use of the various modes. Section 6 discusses the factors that modify mode choice in practice, both at present and in the future and conclusions are given in section 7.


The concept of value and the lifestyle of Shanghai youth have always set the trend for the whole nation. The so-called Western school of lifestyle and ideology espoused by young people in Shanghai stands confronting the Capital school represented by Beijing youth, who set the political trend across the country; they each have their own strength.


The influence of structural variations in compounds of the N-acylalanine type, on their fungicidal activity towards Peronosporales, was examined. Within a series of methyl N-(acyl)-N-(2,6-xylyl)alaninates (I), a quantitative structure-activity relationship was given for the curative action against Plasmopara viticola, through a Hansch-type equation. A deviation from this equation is discussed with reference to benalaxyl (I; acyl=phenylacetyl). Syntheses and qualitative indications of activity are reported for structural changes in the xylyl and in the alanine moieties. Progress in the latter approach is briefly outlined.


Environmental stewardship networks flourish across Australia. Although the environment benefits, this article looks to identify what volunteers draw from their stewardship. The authors adapted 16 questions that purportedly tap environmental stewardship motivation and administered them to a convenience sample of 318 university students and then to 88 people living in rural Australia, who were either active members of environmental groups or voiced concern about local environmental issues. The results suggest that the measure consisting of these questions demonstrates acceptable internal consistency. Factor analyses support three relatively independent aspects of environmental stewardship motivation: (a) developing a sense of belonging, (b) caretaking the environment, and (c) expanding personal learning. Scores on the scale were not strongly correlated with well-being, suggesting that the scale measures more than general feelings of positive affect. Discussion focuses on the benefits of being able to reliably assess environmental stewardship motivation and areas for further development of the scale.


The invention discloses an optimal path establishing method, an MME and a gateway. The method comprises that under the condition that a mobility event occurs in a terminal, the MME determines whether a path connected to a PDN is an optimal path; if the path connected to the PDN is not the optimal path, the MME inquires a local gateway whether data transmission is being performed; and when data transmission is not being performed, the MME initiates a connection re-building flow of the PDN. According to the technical scheme of the invention, the MME initiates a PDN connection release process, a user re-builds PDN connection, and thus, the optimal path is established, it is ensured that a data flow of the user is not interrupted, and user experience is enhanced.


Lumped element model (LEM) for resonant chemical sensors based on the capacitive micromachined ultrasonic transducers (CMUTs) was developed and analyzed with electrical characterization. The CMUTs chip were functionalized with the electrospinning technology. Two Butterworth Van-Dyke (BvD) models for functionalized CMUTs were proposed and analyzed with different DC voltages. Considering the electrical phase with parasitic capacitance, the modified BvD model can be used to illustrate more comprehensive features for both mechanical impedance and phase properties. The parallel capacitance was measured accurately using an impedance analyzer, and the quality factor was calculated based on the proposed model under different DC voltages. These models will provide important theoretical basis for CMUTs-based chemical sensors to further electrical analysis and oscillator design.


In modern military and civil technologies, platforms with equipment on them are often needed to be adjusted to horizontal position rapidly and precisely and keep the platforms stable at the same time. Most leveling systems are implemented with hydraulic system, and they are time-variant nonlinear systems. To leveling both rapidly and steadily with required precision, a PID control strategy based on fuzzy theory was proposed. Electro-hydraulic proportional valve control hydraulic system model was created and analyzed, transfer function of hydraulic legs was obtained and fuzzy PID controller was created in this paper. The proposed method is simulated in Simulink. The simulation result shows that fuzzy PID controller can adjust the platform to horizontal position rapidly and steadily, and improve system performance.


Aristotle stated that philosophy began with "wonder" and that men continue to philosophize because and in so far as they continue to "wonder." Philosophy, in other words, is rooted in the desire to understand the world, in the desire to find an intelligible pattern in events and to answer problems which occur to the mind in connection with the world. By using the phrase "the world" I do not mean to imply that the world is something finished and complete at any given moment: I use the phrase in the sense of the data of outer and inner experience with which any mind is confronted. One might say just as well that philosophy arises out of the desire to understand the "historical situation," meaning by the last phrase the external material environment in which a man finds himself, his physiological and psychological make-up and that of other people, and the historic past. One might discuss the question whether the desire to understand ought to be interpreted or analysed in terms of another drive or other drives. Nietzsche, for example, suggested in the notes which have been published under the title "The Will to Power" that the desire to understand is one of the forms taken by the will to power.


Treatment of aliphatic 1,2-, 1,3- or aromatic o-diamine with carbon disulfide provided the corresponding cyclic pseudothioureas (IIb-j). Heating thiourea (IIa) or these compounds with dimethyl or diethyl acetylenedicarboxylate (IIIa, b) in ethanol resulted a nucleophilic addition of the sulfhydryl group to the C≡C bond accompanied with a ring-closure condensation. Thus a series of alkoxycarbo-methylidene derivatives of 2-imino-4-thiazolidinone (IVa), imidazolo-, benzimidazo-and tetrahydropyrimido (2, 1-b)-3-thiazolidinones (IVb-k) was produced. An orientating experiment of saponifying the ester function of these compounds has also been carried out.

ABSTRACT Introduction: Carcinoma cervix is the second most common cause of death in women worldwide and the most common cause in developing countries. Cervical cancer is considered a preventable gynaecological problem as it has a long premalignant stage which can be detected by exfoliative cytology like papanicolaou smear test. The papanicolaou smear test is a simple, safe, non-invasive, and low-cost effective method for screening cervical cancer in developing countries like Nepal. The aim of the study was to find out the prevalence of cervical papanicolaou smear test screening among patients visiting the Outpatient Department of Gynaecology of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients visiting the Department of Gynaecology of a tertiary care centre after obtaining ethical approval from the Institutional Review Committee. Data from 14 April 2021 to 22 October 2022 were collected between 11 May 2023 to 26 May 2023 from the hospital records. Papanicolaou smear tests among the age group of 21 years up to 70 years were included in the study. Convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 11,173 patients, papanicolaou smear test was done in 572 (5.12%) (4.71-5.53, 95% Confidence Interval). Negative for intraepithelial lesion was the most common cytological pattern seen in 518 (90.55%) patients. The low-grade squamous intraepithelial lesion was the most common among abnormal epithelial cells seen in 29 (5.07%). Conclusions: The prevalence of cervical papanicolaou smear test among patients visiting the Outpatient Department of Gynaecology was found to be similar to other studies done in similar settings.


Under some conditions splash and spray create a significant nuisance to road users and some evidence suggests that they contribute to a small but measureable proportion of crashes. The paper presents a model for predicting splash and spray. The model was developed to assist engineers in decisions concerning the type and priority of maintenance on the road network. Benefits of reducing splash and spay include increased user satisfaction with the network, as well as possible reductions in road crashes and detrimental pollutants being deposited on roadside assets. The developed splash and spray model consists of three sub-modules: (1) A water film thickness model that predicts the water film thickness on pavement surfaces based on pavement surface properties and rain intensity; (2) An exposure model that estimates the amount of water that is going to be projected by the tire given the water film thickness, pavement characteristics, and vehicle speed; and (3) A splash and spray model that predicts pavement surfaces' propensity for splash and spray occurrence based on the other two models. Field tests under controlled rainfall conditions were conducted to assess the impact of various levels of splash and spray on user comfort and perceived safety. Based on the results of these tests, a new method of measuring splash and spray, by computing an occlusion factor, was proposed. The models were implemented in simple prototype tools and validated through a series of additional field experiments. These experiments confirmed that the developed splash and spray assessment model is practical and can be used to support highway engineers' decisions regarding highway design and maintenance.

Ethylene production from methiolbutyric acid (KTBA) is used widely for detecting the production of potent oxidants, e.g., hydroxyl radicals ('OH) in biological systems.'.' For reasons that remain unestablished, this probe is not specific relative to other probes, such as benzoate.' Iron is needed as a catalyst for 'OH.3 Methionine is a known axial ligand covalently bound through sulfur to the heme group in cytochrome c.' Because KTBA is an analogue of methionine, studies were carried out to evaluate the interaction of KTBA with iron in order to determine whether such interactions might help to explain the lack of specificity of KTBA as a probe for 'OH. When ferric chloride (or ferric ammonium sulfate) was added to solutions of KTBA over the range of KTBA:Fe ratios of less than 1:l to 1:1, intensely purplecolored complexes characterized by wide absorbance bands with maxima at 536 nm were observed. These bands tailed gradually into the near-IR and IR regions. At KTBA:Fe ratios of 2:14:1, there was a loss of absorbance over this range and the formation of new absorbance at 460-480 nm. From KTBA:Fe ratios of 6:1-60:1 intensely red-colored complexes formed, characterized by absorbance maxima at 384 nm, a prominent shoulder with increasing absorbance at 480 nm and an isosbestic point at 572 nm. The latter suggests that at high ligand-to-iron ratios complex multimeric species might form? In contrast to results with ferric iron, ferrous addition to KTBA resulted in a time-dependent bathochromic shift of the KTBA spectrum in consort with an increase in the absorbance of 292-330 nm, i.e., the region of a prominent shoulder in the KTBA spectrum. Thus, these results suggest that KTBA forms a ligand that coordinates with both ferrous and ferric iron. Ferrous-KTBA complexes react with H202, resulting in ethylene production (TABLE 1, experiment A). This ability of KTBA to complex with iron is manifested by preventing EDTA (a chelating agent that is often added in conjunction with KTBA to demonstrate a role for iron in 'OH production by biological systems) from ligating iron in the reaction medium. The data in TABLE 1, experiment B, show that KTBA tends to maintain the ferrous oxidation state to a much greater degree than does EDTA. Thus, in evaluating a role for iron in 'OH-generating systems the order of addition of the scavenging agent with respect to EDTA becomes an important consideration. For example, if KTBA is added before EDTA in a reaction system, the rate of autoxidation of iron is more refractory than if EDTA is added before the KTBA. This can be seen to result in an order of magnitude greater ethylene production when KTBA is added before EDTA than when the order of addition is reversed. Similarly, phosphate buffer, pH 7.4, also is known to accelerate the rate of


The outbreak of Monkeypox was declared a public health emergency of worldwide concern by WHO following the (COVID-19) pandemic. The number of reported cases of both suspicion and confirmation has increased in recent years, from over 19,000 between 2000 and 2019 to over 15,600 between 2021 and 2022, and day by day the cases of monkeypox have been reported in 12 member states to three WHO regions. As of May 21, 2022, 92 confirmed cases of monkeypox and 28 suspected cases had been reported to the WHO from more than 12 countries. By the 21st of June 2022, a total of 2677 confirmed cases had been recorded from the UK and other European and non-European countries. According to an extensive literature survey, the total number of registered cases of MPXV was 59,147 between January 2022 to September 14th, 2022, demonstrating that MPXV can spread significantly amongst people and may as a result pose a serious threat to public health with international repercussions. In clade II MPXV virus is currently occurring outside of Africa the WHO reported 25,047 confirmed cases as of August 2nd, 2022. Here, we review current better understanding, and studies on monkeypox, including its history, current scenario, epidemiology, causative agent, symptoms, diagnosis, treatment, limitations, and the new face of monkeypox, its unusual outbreak attributed to the transformation of transmission and also discussed case studies is discussed in this article.

Med. 281: 542-543 (1969). These two reports document the occurrence of subacute constrictive pericarditis in three patients with chronic renal failure. Two of the individuals were maintained with a form of chronic dialysis; one with intermittent peritoneal and the other with weekly hemodialysis treatments. Acute pericarditis was recognized in all patients prior to the development of constriction at intervals from 2 1⁄2 to 4 months prior to demise. All patients expired and postmortem examination revealed a thickened fibrous pericardium measuring up to 1 cm in thickness. These reports emphasize that although constrictive pericarditis secondary to chronic uremia is extremely unusual it does occur. Authors'addresses: Dr. T.A.

London, M. DiFiglia, A.I. Sutnick, B.S. Blumberg: New Engl. J. Med. 281: 571-578 (1969). In a chronic hemodialysis unit all 9 patients and 6 of 15 staff members within one year had evidence of viral hepatitis. Australia antigen (Au [1]), a virus-like particle associated with acute and chronic viral hepatitis but not other liver disease was found in the blood of 8 of the 9 patients and in the two staff members with hepatitis tested. Clinical and laboratory features of hepatitis in the staff and the patients in dialysis were different. In the former an acute disease characterized by serum bili-rubin over 3 mg per 100 ml, SGPT over 1000 units and duration of SGPT elevations of less than 10 weeks developed. The patients on dialysis manifested a chronic anicteric disease, with SGPT's under 1000 units but SGPT elevations lasting for 20 weeks or more; the cases were detected only because of frequent testing for Au (1) and SGPT. Susceptibility of patients with chronic renal disease to chronic Au (1) hepatitis is probably related to impaired immunologic responsiveness. Author's address: Dr. W.

Inflammatory arthritides (IA) can affect diverse body tissues beyond joints, including the heart [1,2]. Particularly in chronic inflammatory states, circulating immune mediators can also induce central nervous system inflammation [3]. Nevertheless, little is currently known about the consequences of cardiac inflammation on the occurrence of brain lesions in these patients.We hypothesized that patients with IA and cardiac symptoms would show evidence of brain lesions, and that the presence of cardiac inflammation would be associated with the presence of brain lesions. We thus investigated patients with IA and compared them to a cohort of disease-controls using combined brain/heart magnetic resonance imaging (MRI).Patients with IA and shortness of breath, chest pain and/or palpitations (n=25) were compared to age-matched disease-controls with non-autoimmune cardiovascular disease (CVD) (n=30) using a 1.5T MRI system. The presence of white matter hyperintensities (WMHs) was investigated in subcortical/deep/periventricular white matter, the basal ganglia, pons, brainstem, or mesial temporal lobe. Cardiac function and inflammation were investigated using standard protocols. Patients with IA were diagnosed with rheumatoid arthritis [14 (56%)], ankylosing spondylitis [5 (20%)], juvenile rheumatoid arthritis [3 (12%)], mixed connective tissue disease [2 (8%)] or enteropathic arthritis [1 (4%)]. Disease controls had various CVDs including coronary artery disease [5 (17%)], myocarditis [5 (17%)], hypertension [3 (10%)], Duchenne muscular dystrophy [3 (10%)], and others.Patients with IA and disease-controls respectively had a median (IQR) age of 45 (39, 51) vs. 53 (40, 57) years (p=0.269), and 16 (64%) vs. 7 (23%) were women (p=0.002). WMHs were detected in ≥1 brain area in 15 (60%) patients with IA and 15 (54%) disease-controls (p=0.620). The majority of participants had WMHs in subcortical [29 (53%)], periventricular [5 (9%)], or deep WM [11 (20%)]. Some also had cortical lesions [5 (9%)], while basal nuclear, brainstem and mesial temporal lesions were rare [1 (2%) for all]. Amongst subjects with WMHs, the median (IQR) number of brain lesions in patients with IA and disease-controls was 1 (1, 2) for both groups (p=0.635). There were no significant differences in the distribution of brain lesions between groups. Amongst patients with IA, each 0.1-unit increase in cardiac T2-ratio was associated with an increased probability of WMH occurrence [odds ratio (95%): 1.29 (1.05-1.59), p=0.016] and higher cardiac T2-ratio (per 0.1-unit change) and extracellular volume fraction (ECV) were associated with a higher WMH lesion burden in linear regression analysis [Beta (95% confidence interval): 0.08 (0.01-0.15), p=0.021 and 0.22 (0.03-0.41), p=0.027, respectively]. MRI-derived left/right-ventricular ejection fraction, early/late-gadolinium enhancement and T1/T2 mapping were not associated with the presence of WMHs.In patients with IA and cardiac symptoms, 60% showed evidence of subclinical brain lesions, which was on average as prevalent as in age-matched disease-controls with non-autoimmune CVD. Higher myocardial T2-ratio, an MRI-derived surrogate of myocardial edema, was associated with the presence of WMHs, and higher T2-ratio as well as myocardial ECV values were predictive of higher WMH burden. Further research is required to determine the clinical relevance of these findings.[1]Venetsanopoulou AI, et al.

In the following text, I briefly analyze and compare the voice of the different races of Mottled Owl (Ciccaba virgata). I also try to quantify the extent of any vocal differences using the criteria proposed by Tobias et al. (2010), as a basis for taxonomic review. I have made use of sound recordings available online at Xeno Canto (XC) and the Macaulay Library (ML). The available recordings suggest that there are two distinct vocal groups. Group 1. Song is a series of typically 4–9 short emphatic sharply overslurred hoots. This voice can be heard in Middle America, Pacific South America (south to NW Peru) and NW South America, as illustrated in the following examples grouped by (presumed) subspecies: squamulata

The invention discloses a granulation device for making spheroidal particle from melt liquid, which relates to the field of melt liquid forming technology. The device is characterized in that the granulation device comprises: a melt liquid chamber with uniform pressure, a distribution plate with multiple nozzles mounted longitudinally on the melt liquid chamber, nozzle switching parts connected with distribution plate, a tower flange, and a tower connected with the flange. The nozzle switching part mounted on the side of the distribution plate and controlled by a valve is a channel for switching cooling medium and heating medium. On the tower, an inlet for cooling liquid and an outlet for product are arranged. When the density of melt liquid is more than that of cooling liquid, the top-down mounting sequence is melt liquid chamber, distribution plate, tower body, inlet distribution device of cooling liquid, and product discharging device. The melt liquid flows down via nozzle, liquid drop moves down and is cooled into particle in the tower and is discharged by the lower discharge device. The granulation device is characterized by high granulation efficiency and heat changing efficiency, energy saving and low cost.


Positions of actuators play an important role in active vibration control, which affect not only the performance of vibration control but also the stability of whole system, especially for flexible structures. On optimal placement of actuators, many scholars have proposed a variety of optimization criteria, although some of these criteria have generality, but are complex to implement, and the results obtained by using closed-loop design idea to study the optimal placement of actuators are usually affected by initial conditions, the weight matrix and different control laws; which make the problem complicated, and this couldn't improve the effects of vibration control. In fact, before the system design, the initial conditions are difficult to determine, and the placement of the actuators should not affected by initial conditions and control laws, but should only by the inherent characteristics of the system and the external disturbances. In this paper, for a whole-spacecraft vibration isolator using piezoelectric stack actuators, dynamic sensitivity analysis method was used to derive an optimization criteria for piezoelectric stack actuator's placement, this criteria only related to the dynamic characteristics of the structure and the features of disturbance, but wasn't affected by initial conditions and control methods. By using the criteria, optimal placement of the piezoelectric actuators on the whole-spacecraft vibration isolator was studied; simulation results comparison verified the validity of the criteria, and obtained conclusion that different disturbance characteristics and output performances have great effects on the optimal placement.


Firstly the characteristics of production process and management process were expatiated.Secondly a formal difinition of coordinated process model(CPM) was proposed.Thirdly an example was given to show the distinctions between CPM and existing methodlogies.

The Ca2+ and redox‐sensing enzyme Ca2+/calmodulin‐dependent kinase 2 (CaMKII) is a crucial and well‐established signalling molecule in the heart and brain. In vascular smooth muscle, which controls blood flow by contracting and relaxing in response to complex Ca2+ signals and oxidative stress, surprisingly little is known about the role of CaMKII. The vasodilator‐induced second messenger cAMP can relax vascular smooth muscle via its effector, exchange protein directly activated by cAMP (Epac), by activating spontaneous transient outward currents (STOCs) that hyperpolarize the cell membrane and reduce voltage‐dependent Ca2+ influx. How Epac activates STOCs is unknown. In the present study, we map the pathway by which Epac increases STOC activity in contractile vascular smooth muscle and show that a critical step is the activation of CaMKII. To our knowledge, this is the first report of CaMKII activation triggering cellular activity known to induce vasorelaxation.


Non‐small cell lung cancer (NSCLC) remains a leading cause of cancer mortality worldwide. New therapies for NSCLC, suchasmonoclonal antibodiesor tyrosine kinase inhibitors, have targeted Her1, the human epidermal growth factor receptor which is over‐expressed in NSCLC, but many tumors become resistant. In the present study, Aguiar Alpizar et al. describe a prime/boost vaccination protocol using the extracellular domain (ECD) ofmurineHer1. In this protocol, a single injection of a recombinant lentivirus expressing the Her1 ECD was followedby twoHer1proteinboosts. The authors demonstrated that such a protocol, which generates a robust antiHer1 immune response, breaks the tolerance in mice and can be used to treat murine metastatic lung cancer.


Background: The solution of problems of school nutrition requires a creation of program and project management technologies of school catering focused on children's health.
Objective: To elaborate approaches to introducing the system of risk management in school catering.
Materials and methods: In 2019–2021, specialists from various departmental authorities were brought together to conduct the study aimed at identifying and solving challenges related to school nutrition. We conducted a questionnaire-based survey of 43,565 respondents from 135 schools in the city of Yekaterinburg for the purposes of an integral assessment of their satisfaction with school meals. We also analyzed 10,623 food samples, estimated nutritional values of dishes, and evaluated implementation of the principles of Hazard Analysis and Critical Control Points (HACCP) in 12 school canteens in view of the results of health checkups of 53,572 students.
Results: We established the main reasons for refusal of school meals and proved the relationship between general satisfaction with school nutrition and school catering companies. In terms of nutritional value, 70.5 % of the collected food samples did
not comply with the estimates provided in technical documentation. We observed no systemic risk management of food hygiene violations. The estimated proportion of schoolchildren with diet-related diseases ranged from 15 to 72 %. Our findings were used to develop recommendations for improvement of school meals and an algorithm of managerial decision-making envisaging cooperation of organizations of various levels in providing healthy nutrition to schoolchildren.
Conclusion: A systemic approach and combined efforts of various authorities are necessary to promote healthy eating at school. Elaboration of methods for reliable assessment of the nutritional value of diets and health-related nutrition factors is
essential. The developed comprehensive approach to managerial decision-making will contribute to providing healthy and appealing school meals. The effectiveness of joint activities will depend on each member of the team of specialists involved in organizing school catering.


This paper presents a novel valance intersubband laser based on Si-based Si-Ge superlattice grown on a relaxed Si1-xGex buffer layer. Effective mass theory is used to calculate the inplane valence subband dispersion of strain-symmetrized silicon/germanium superlattices within 4×4 Luttinger model. The valence band offsets and strain parameters are calculated by Van de Walle's model-solid theory. Analysis of the in-plane energy dispersion shows that the light-hole effective mass is inverted in the k-space region. The laser structure can be desigend with a simple quantum cascade scheme. Our calculation shows that with the electrical pump, it is possible to achieve population inversion between the two subbands in local k space where the light-hole effective mass is inverted. Optical gain of the order 100/cm can be achieved wiht a pumping current density 10KA/cm2.


High-pulse energy picosecond laser systems provide industrial-level reliability combined with the performance features required for many ultrafast material processing applications. Current diodepumped solid-state systems provide pulse energies into the 100's of microjoules at 1064 nm wavelength and pulse widths of approximately 10 picoseconds, which allows effective "cold" ablation of most materials with high efficiency. Average power of these systems is scalable up to 50 W and will further increase into the multi-100 W range, allowing for very high speed picosecond micromachining.

This article first reviews the basics of picosecond micromachining, gives a short perspective on the development of these lasers over the last few decades, then summarizes their current performance. We review some of the applications that are enabled with these lasers, before we discuss future developments in this rapidly changing field.


To improve the success of grafted tomato plants, the response under different types of lighting has been evaluated. The lights used are compact fluorescent, high efficiency fluorescent, standard fluorescent and pure Blue-Light-Emitting Diodes. The assay was conducted in a culture chamber under the following conditions: temperature (night-day) 17.5/19.8 degreesC (0.8 +- 0.2/0.1 degreesC), relative humidity 56.44/72.40% (6.65 +- 0.01%) and radiation 92, 70, and 36 Wm-2. The tomato (Solanum lycopersicum L.) grafting method used was tube grafting with a small grafting clip using the cultivars Myla as scion and Maxifort as rootstock. Spectral radiation was measured at canopy level. Fresh and dry biomass in partitioning organs (leaves, stems and roots), Indol Acetic Acid (IAA), proline and reducing sugars were quantified. Standard fluorescent lamps have a very interesting spectral quality for grafting applications due to their B:R (blue:red), B:FR (blue:far red), PAR:NIR (Photosynthetically Active Radiation:Near Infrared) and R:FR (Red:Far Red) ratios; grafted plants under standard fluorescent lamps present lower proline concentrations (990mug per g of fresh weight) and higher sugar concentrations (27mug per g of fresh weight) than plants under other treatments. Furthermore, standard fluorescent lamps ensure the highest stem and root growth as well as an adequate water status.


We search for sterile neutrinos in the holographic dark energy cosmology by using the latest observational data. To perform the analysis, we employ the current cosmological observations, including the cosmic microwave background temperature power spectrum data from the Planck mission, the baryon acoustic oscillation measurements, the type Ia supernova data, the redshift space distortion measurements, the shear data of weak lensing observation, the Planck lensing measurement, and the latest direct measurement of $H_0$ as well. We show that, compared to the $\Lambda$CDM cosmology, the holographic dark energy cosmology with sterile neutrinos can relieve the tension between the Planck observation and the direct measurement of $H_0$ much better. Once we include the $H_0$ measurement in the global fit, we find that the hint of the existence of sterile neutrinos in the holographic dark energy cosmology can be given. Under the constraint of the all-data combination, we obtain $N_{\rm eff}= 3.76\pm0.26$ and $m_{\nu,\rm sterile}^{\rm eff} 0$ in the holographic dark energy cosmology is at the $2.75\sigma$ level and the massless or very light sterile neutrino is favored by the current observations.


Asteroseismology of stars that exhibit solar-like oscillations are enjoying a growing interest with the wealth of observational results obtained with the CoRoT and Kepler missions. In this framework, scaling laws between asteroseismic quantities and stellar parameters are becoming essential tools to study a rich variety of stars. However, the physical underlying mechanisms of those scaling laws are still poorly known. Our objective is to provide a theoretical basis for the scaling between the frequency of the maximum in the power spectrum (νmax) of solar-like oscillations and the cut-off frequency (νc). Using the SoHO GOLF observations together with theoretical considerations, we first confirm that the maximum of the height in oscillation power spectrum is determined by the so-called plateau of the damping rates. The physical origin of the plateau can be traced to the destabilizing effect of the Lagrangian perturbation of entropy in the upper-most layers, which becomes important when the modal period and the local thermal relaxation time-scale are comparable. Based on this analysis, we then find a linear relation between νmax and νc, with a coefficient that depends on the ratio of the Mach number of the exciting turbulence to the third power to the mixing-length parameter.


The voltage bias that causes a transition from direct tunneling to Fowler–Nordheim tunneling in the current-voltage characteristic of a metal/HfO2/SiO2/n-Si capacitor was measured. The transition occurs in the negative gate voltage regime and can be attributed to conduction of electrons from the metal through a defect level in the HfO2 or to conduction of holes from the Si through the valence band of the HfO2. The dependence of the determined barrier height on the gate-metal work function indicates the validity of the latter model.


This paper examines the effect of investors' portfolio rebalancing frequency and out-of-balance threshold on the portfolio's scaled return (return/risk ratios). Using data from 1926-2003, we examine the return/risk ratio for 19 different stock/bond portfolios with policy weights of 5%/95%, 10%/90%, and so on through 95% bond/5% stock. For each of these 19 portfolios, we calculate scaled return (mean return  standard deviation of return) under 60 different time-based policies of rebalancing every 1 month, 2 months, and so on through 60 months. Next, we examine 20 threshold-based policies involving rebalancing when portfolio weights deviate from policy weights by 0.5%, 1%, and so on through 10%. Finally, we conduct both analyses again under two distinct Federal Reserve monetary policies: expansionary and contractionary.Our conclusions are as follows. Rebalancing frequency and threshold have a significant effect on scaled return. Specifically, for many model portfolios examined, deferring rebalancing to even as long as four years was superior to a monthly or quarterly rebalancing policy. For percentage threshold-based policies, the superior (inferior) outcomes were associated with rebalancing only when portfolio weights were 5% or more (less than 5%) out of balance.From the perspective of both frequency and threshold levels, patient rebalancing policies tend to dominate quick-trigger policies, even before trading costs and taxes are considered. If such costs were taken into account, the advantage in favor of patient policies would be even more dramatic.The best rebalancing policy is dependent on, and can be planned around, the Fed's prevailing monetary policy. We find that Federal Reserve monetary policy has a discernible impact on scaled returns due to rebalancing, with restrictive monetary periods associated with less ambiguous conclusions. During restrictive periods, rebalancing more frequently than every 10-20 months is a suboptimal strategy.Why does a relatively long time interval (and higher threshold) for rebalancing outperform a shorter time period (and lower threshold)? One, partial, explanation comes from the observation by various researchers including Poterba and Summers (1988) and Fama and French (1988), of positive short-term autocorrelation among stock returns and negative longer-term autocorrelation. To the extent that returns are positively correlated in the short run, investors can take advantage of momentum by sitting tight. In contrast, mean reversion in returns over 3-5 years confirms the efficacy of rebalancing about that often.


The development of social media enables fake news to be expressed in a multi-modal form, which is disseminated on various social platforms and brings harmful social impacts. To handle this challenge, the fake news detection task was proposed to examine whether false information is contained in multi-modal news. Existing methods exploit various approaches with cross-modal interaction and fusion, which have proven to be effective in detecting common fake news. However, although the description of multi-modal news is narrated around entities, the previously developed methods pay less attention to this characteristic. They do not explore its benefits to the detection task and underperform with respect to the detection of fake news that requires entity-centric comparisons. To make up for this omission, we explore a novel paradigm to detect fake news by aligning and fusing multi-modal entities and propose the Entity-oriented Multi-modal Alignment and Fusion network (EMAF). Our work adopts entity-centric cross-modal interaction, which can reserve semantic integrity and capture the details of multi-modal entities. Specifically, we design an Alignment module with the improved dynamic routing algorithm and introduce a Fusion module based on the comparison, the former aligns and captures the important entities and the latter compares and aggregates entity-centric features. Comparative experiments conducted on multiple public datasets, including Weibo, Twitter, and Reddit, reveal the superiority of the proposed EMAF method, and extensive analytical experiments demonstrate the effectiveness of our proposed modules.


Although there is often fierce competition among schools and universities for the recruitment of academically talented minority students, little is known about their needs, interests, and future plans. This article provides insights into the concerns of talented young minority people by describing the profiles of approximately 3,545 minority students who scored in the top 5% on the American College Test Assessment. The authors examine the relationship of specific minority group membership and gender, postsecondary educational plans, career interests, needs for services, desires for extracurricular activities, and satisfaction with educational experiences. Implications are drawn for counselors, advisers, and administrators striving to improve their ability to serve academically talented minority students.


Digital literacy is defined as the ability to understand and use information in various forms from various sources accessed through computer devices. Digital literacy will create a society with a critical-creative mindset and views. Provocative issues will not easily consume it, become victims of hoax information, or victims of digital-based fraud. Residents of Hurung Village, Banama Tingang District, Pulang Pisau Regency are partners in this community service activity who are active users of digital technology via mobile phones to access the internet and interact with other people. However, in digital technology, partners have not been able to distinguish true or false information and forward information obtained from social media or unclear sources. Likewise, in the search for information, still using sources or references that are not valid. So that the information obtained cannot be justified. In this service activity, the service team created digital media using a village profile website to support digital literacy for Hurung village. The activity was carried out in three stages, namely material presentation, mentoring, and training on the use of village profile websites. With this activity, it is hoped that it can be helpful to add insight, knowledge and build Hurung village to become a pioneer village of digital literacy


Abstract The frequency-dependent differential capacitance of an amorphous silicon Schottky barrier is calculated as a function of d.c. bias using a simple model of the Schottky barrier and an assumed form for the density of electronic states, n(E), of the silicon. The results show that at frequencies as low as 1 Hz the capacitance of the Schottky barrier can be considerably different from the static capacitance because of the slow response of the electron occupancy of localized states. A detailed development of the theory is presented to demonstrate the way in which information on n(E) is contained within the capacitance-voltage (CV) results. The deduction of n(E) from the CV results is possible if the static capacitance is known but, when relaxation effects are significant, there appears to be no simple way of obtaining n(E) directly.


Bax Farmhouse is one of several middling-sized houses in Kent that owe their origins to medieval building traditions, but embrace some of the new forms of the sixteenth century. The ostentatious use of stone, flint, brick and timber, which together make up its primary building materials, sets it apart from many of its contemporaries, while the crow-stepped gable of its east wing demonstrates that this is a house whose importance once belied its modest size. A date stone inscribed 1567 arguably refers to all the primary features visible today, and also to a western wing which was demolished in the nineteenth century. These features put Bax Farmhouse out of the run of everyday Kent houses. Despite such unusual qualities, Bax Farmhouse demonstrates an abiding characteristic of Kent estates, which was to support the construction and maintenance of generally small rather than stately country houses.


Because of interdependence between resident population (e.g., as customers or manpower) and economic activities (e.g., shops or services), relocating firms' destination choice plays an important role in comprehensive land use models. However, due to a lack of data at the micro level enabling the estimation of discrete choice models, little research exists on this topic. In this paper, data from commercial registers of three Swiss cantons, St. Gallen, Appenzell Ausserrhoden, and Appenzell Innerrhoden, were analysed. This dataset provides information on more than 54,000 firms and autonomous plants from 1991 to 2006. Variables such as local taxes, governmental business friendliness, and accessibilities have been tested in a nested logit (NL) model for different business sectors. The results show that distance, local taxes, and cantonal business development strongly influence relocating firms' destination choice. Furthermore, significant differences between sectors can be identified. For instance, residents with graduate degrees have a significant and high impact on business services, but a minimal effect on businesses in wholesale trade and personal services.


This study was undertaken to examine the content of advertisements of political candidates for governor in a Deep South state, an area historically known for its demagoguery. Media observers claim that the growing use of advertising in mass media by politicians has changed the method of politicking in the Deep South, moving politicians away from the rhetoric of the demagogue to more issue-oriented campaigns. Since there is no live, and perhaps angry, audience to face when presenting a print or electronic message, are today's candidates more interested in presenting issues rather than personalities? Former Gov. George Wallace of Alabama, said in an interview: There is no way a candidate for statewide election can politic as I did 25 years ago. You can't get around fast enough to do it on a personal basis. besides folks won't come out for a political rally anymore. They'd rather stay at home and look at television. Today it's all media politics and if a fellow doesn't haw more than a million dollars to spend he better forget it.' Political advertising and the enormous sums of money spent on it have come under serious scrutiny by the federal government in the past two decades. The government's reaction has included various FCC regulations and the Campaign Reform Act of 1972. Yet, despite regula-


Objectives The purposes of current study was to examine the longitudinal mediation effects of avoidance behaviour and positive affect in the relationship between social interaction anxiety and depression.
Methods Considering the longitudinal design of this study, an online survey was presented four times in three weeks. And Social Interaction Anxeity Scale(SIAS), Liebowitx Social Anxiety Scale(LSAS), Positive Affect and Negative Affect Scale(PANAS), The Center for Epidemiologiacl Studies Depression Scale(CES-D) are used for measurement. Also, The mediating effect was examined through Autoregressive Cross-Lagged Modeling Analysis for 201 college students(male 52 and female 149) who participated in all measurement periods.
Results First, social anxiety, avoidance behaviour, positive affect and depression was stable over time. Second, the longitudinal effects among all the variables were statistically significant, except for the effect of the avoidance behaviour on positive affect. Third, while the avoidance behaviour and positive affect displayed partial mediation effects in the relationship between social anxiety and depression, the sequential mediation effects of avoidance behaviour and positive affect were not statistically significant.
Conclusions The results of this study are significant in that verified the mediation effects of avoidance behaviour and positive emotions in the relationship between social interaction anxiety and depression through short-term longitudinal design. Also, this study suggests that therapeutic intervention aimed at reducing avoidance behavior or increasing positive emotional experience in people suffering from social anxiety disorders is an important factor to be considered to prevent the onset of depression in the future.


Observations show that the accretion flows in low-luminosity active galactic nuclei probably have a two-component structure with an inner, hot, optically thin, advection-dominated accretion flow (ADAF) and an outer, truncated, cool, optically thick accretion disk. As shown by Taam et al., the truncation radius as a function of mass accretion rate is strongly affected by including the magnetic field within the framework of disk evaporation model, i.e., an increase in the magnetic field results in a smaller truncation radius of the accretion disk. In this work, we calculate the emergent spectrum of an inner ADAF + an outer truncated accretion disk around a supermassive black hole based on the prediction by Taam et al.. It is found that an increase in the magnetic field from β = 0.8 to β = 0.5 (with magnetic pressure pm = B2/8π = (1 − β)ptot, ptot = pgas + pm) results in a factor of ∼8.7 increase in the luminosity from the truncated accretion disk. Meanwhile, results of the peak emission of the truncated accretion disk shift toward a a factor of ∼5 higher frequency. We found that the equipartition of gas pressure to magnetic pressure, i.e., β = 0.5, failed to explain the observed anti-correlation between L2–10 keV/LEdd and the bolometric correction κ2–10 keV (with κ2–10 keV = Lbol/L2–10 keV). The emergent spectra for larger values of β = 0.8 or β = 0.95 can explain the observed L2–10 keV/LEdd–κ2–10 keV correlation. We argue that in the disk evaporation model, the electrons in the corona are assumed to be heated only by a transfer of energy from the ions to electrons via Coulomb collisions, which is reasonable for accretion with a lower mass accretion rate. Coulomb heating is the dominated heating mechanism for the electrons only if the magnetic field is strongly sub-equipartition, which is roughly consistent with observations.


In this paper, we focus on the asymptotic capacity and delay, and their tradeoffs in mobile ad hoc networks (MANETs). As we all know, some fixed rate communication models such as the protocol model and the physical model have been studied in the past. However, our work aims to investigate the impact of an adaptive rate communication model on capacity-delay tradeoffs in MANETs under classical mobility models. Specifically, we adopt a well-known adaptive rate model called the generalized physical model (GphyM). The mobility of nodes is characterized by two broad classes of practical mobility models and they are hybrid random walk models and discrete random direction models. The two models generalize many mobility models studied in the literature, including the random walk, i.i.d., Brownian, and random way point models. For each mobility model, we derive the optimal delay for the optimal per-session unicast capacity (that of constant order Θ(1)) under the generalized physical model, depending on the individual parameters of mobility models. In particular, we show that for the i.i.d. model, compared with those under the protocol and physical models, the adaptive feature of link rate under the generalized physical model results in a significant decrease in the optimal delay for the optimal capacity; more precisely, both the optimal capacity and optimal delay can be simultaneously achieved, while there is no improvement for the random way-point model.
