Violence in the workplace affects every sector and industry in the United States, and it can take on many forms, from verbal threats to front page workplace shooting events – and everything in between. In fact, the issue is so prevalent that death by homicide is the fourth leading cause of workplace deaths. The impact of workplace violence on employers goes beyond the immediate concern for the safety and welfare of employees. Aside from the expected direct financial costs of increased security, insurance, and legal fees, there are indirect costs that impact the bottom line. Workplaces with employees who experience or witness workplace violence tend to have new obstacles to productivity, including lower morale, absenteeism, labor-management conflict, and increased turnover. This paper will show that violence can be predicted to a point, and prevention is then a matter of understanding those characteristics that lead to violence and addressing them before the cycle reaches a peak that ends in bloodshed. There is no single method of prevention that is reliably successful, and there is no single circumstance in which prevention methods should be used. Instead, a program of violence prevention would include activities that permeate all levels of the organization, instilling something akin to an organizational culture that is focused on prevention of aggression and violence. Violence in the workplace affects every sector and industry in the United States, and it can take on many forms. While frequently quoted statistics count only those incidents in which days away from work or death results, the numbers increase significantly when considering less dramatic situations. Fistfights, an employee slapping a colleague, a manager shouting at a subordinate to the point where that person is backed into a corner – while perhaps not considered in statistics, these are frequently occurring examples of violent behavior. However, both employers and employees alike are most alarmed by more serious incidents - those that make the headlines. Consider these recent events:


Analysts have frequently neglected children's economic activities as peripheral and/or morally threatening, but recent work has challenged both characterizations. Direct observation of children's participation in production, distribution and consumption reveals their extensive and consequential involvement in the economy. The organization, meaning and consequences of children's economic activity vary significantly among three different sets of social relations: with other household members, with agents of organizations outside households and with other children. A review of exemplary studies identifies an extensive agenda for new child-centered studies of production, distribution and consumption.


ABSTRACT

          Knowing the authentic hadiths of those which are poor is all important and necessary issue , and it needs skilled specialists, including the Hafiz Abdul Rahim bin Al Hussein, Abu Al Fadl Al Iraqi. This word came in his book four times, twice from the author Al-Hafiz Al-Iraqi, and twice he transmitted it from Imam Al-Tirmidhi, , The first had a weak chain of transmission and it is alright for others . Because of its many ways, the second is weak, and the third  is Marfooa  and  mawqoof,   the Marfooa   is  poor  and the  Mawqoof  is alright .


8509 Background: The PACIFIC trial demonstrated that a year of consolidation PD-(L)1 inhibition following concurrent chemoradiation (CRT) for unresectable stage III NSCLC improves overall survival (OS). The optimal duration of consolidation IO therapy in this setting is undefined. Studies in metastatic NSCLC demonstrate that combination PD-(L)1/CTLA-4 inhibition improves OS over chemotherapy alone. This trial evaluated the use of combination Nivolumab (N) plus Ipilimumab (IPI) or N alone for up to 6 months in unresectable stage III NSCLC after concurrent CRT. Methods: This is a randomized phase II, multicenter trial of 105 pts with unresectable stage IIIA/IIIB NSCLC. All pts received concurrent CRT and were then enrolled and randomized 1:1 to receive N 480mg IV q4wks (Arm A) for up to 24 weeks or N 3mg/kg IV q2 wks + IPI 1mg/kg IV q6 wks (Arm B) for up to 24 weeks. The primary endpoint is 18-month PFS compared to historical controls of CRT alone for arm A (30%) and CRT followed by Durva for arm B (44%). Secondary endpoints include OS and toxicity. Results: From 9/2017 to 4/2021, 105 pts were enrolled and randomized, 54 to N alone (A) and 51 to N + IPI (B). The baseline characteristics for arm A/B: median age (65/63), male (44.4%/56.9%), stage IIIA (55.6%/56.9%), stage IIIB (44.4%/43.1%), non-squamous (57.4%/54.9%), and squamous (42.6%/45.1%). The percentage of pts completing the full treatment was 70.4% on A and 56.9% on B (p = 0.15). Median f/u was 24.5 and 24.1 months on A and B, respectively. The 18-month PFS was 62.3% on A (p < 0.1) and 67% on B (p < 0.1), and median PFS was 25.8 months and 25.4 months, respectively. Median OS was not reached on either arm, but the 18- and 24-month OS estimates were 82.1% and 76.6% for A and 85.5% and 82.8% for B, respectively. Treatment-related adverse events (trAE) on arm A/B were 72.2%/80.4%, and grade ≥3 trAEs on arm A/B were 38.9%/52.9%. There was 1 grade 5 event on each arm (COVID19-A, Cardiac Arrest-B). The number of pts with grade ≥2 pneumonitis were 12 (22.2%) on A and 15 (29.4%) on B, with 5 (9.3%) and 8 (15.7%) grade ≥3 events, respectively. The most common ( > 10%) non-pneumonitis trAEs on A were fatigue (31.5%), rash (16.7%), dyspnea (14.8%), and hypothyroidism (13%), and on B were fatigue (31.4%), diarrhea (19.6%), dyspnea (19.6%), pruritus (17.7%), hypothyroidism (15.7%), rash (15.7%), arthralgia (11.8%), and nausea (11.8%). Conclusions: Following concurrent CRT for unresectable stage III NSCLC, both N and N + IPI demonstrated improved 18-month PFS compared with historical controls despite a shortened interval (6 months) of treatment. OS data are still maturing but 18- and 24-month OS estimates compare favorably to prior consolidation trials. Toxicity for N alone was similar to prior single-agent trials, and the combination of N + IPI resulted in a higher incidence of trAE's, although consistent with prior reports. Clinical trial information: NCT03285321.


Abstract : This paper reports on the use of Q-analysis to study the degree of inter-ethnic linkages among the Serbs, Croats, and Muslims in Bosnia-Herzegovina as reflected in the results of public opinion poll data provided by the United States Information Agency (USIA). The degree of inter-group linkage is specified in terms of a property known as the Q-connectivity. Changes in this property reflect changes in the degree of mutual concurrence with specific sets of public opinion poll data. The study uses the Q-analytic approach to examine the degree of linkage and division among these ethnic groups in Bosnia-Herzegovina during the period from December 1995 to February 1998. Two clusters of poll data were used in the study. The first cluster, the Ethnic Relations Data Set, reflects answers to questions about each group's attitudes toward, and relationship with, the other ethnic groups; whether they can forget the past and live peacefully together; and their confidence level in the local government, police, and courts. Q-analysis of this data set shows that the groups have confidence in the local government, the police, and the courts, and a need to forget the injustices of the past. However, they also have generally unfavorable opinions of their counterparts, pessimism about peaceful coexistence, and fear of living as an ethnic minority. The second cluster, the International Relations Data Set, reflects the opinions of these groups on the Dayton Peace Accords, the status of the country and its government, the presence of peacekeeping troops, and fear that fighting will start again. Q-analysis of this data set shows a relatively high level of agreement with the Dayton Peace Accords, the belief that the Accords are better than continued war, and acceptance of peacekeeping troops, but also fear that fighting might break out again.

ABSTRACT
This study aimed to explore and identify the types of tubers, processing methods, utilization, morphological characteristics and nutritional content of tuber plants found in Rendang District and Bebandem District, Karangasem Regency. The method used was descriptive method with interview techniques, field observations, exploration, collection and documentation. The results showed there are 9 types of tubers were found, namely Manihot esculenta Crantz., Ipomoea batatas L., Colocasia esculenta L., Xanthosoma sagittifolium (L.) Schott, Amorphophallus campanulatus BI., Dioscorea alata L., D. bulbifera L., D. bulbifera L., D. hipsida Dennts, and D. aculeata. There were three variants were identified for Manihot esculenta, 5 variants of Ipomoea batatas, 4 variants of Xantosoma sagittifolium, 1 variant of Colocasia esculenta, 1 variant of Amorphophallus campalunatus, 4 variants of D. alata, 2 variants of D. aculeata, 1 variant of D. hipsida and 2 variants of D. bulbifera. The utilization of each type of tubers varies : cassava, taro, and sweet potato can be boil, grilled, steamed, fried, while the other 2 types, namely gadung and suweg, require special treatment before consumption because these tubers can cause poisoning. Utilization of other organs from the type of tubers can be used as vegetables (cassava leaves, sweet potato leaves, taro leaves, taro leaf stalks), traditional medicine (uwi and sweet potato), animal feed (taro stems, sweet potato leaves) and as a support for the family economy. The description and morphological character of each type of tuber are different. Differences in morphological characters are seen in stature, tubers (shape, structure, size, color), stem (shape, structure, size, color), leaves (shape, structure, size, color). All tubers found can be alternative carbohydrate source to rice because they have complex nutritional content.
Key words : Manihot esculenta Crantz., Ipomoea batatas L., Colocasia esculenta L., Xanthosoma sagittifolium (L.) Schott, Amorphophallus campanulatus BI., Dioscorea spp.


Employer exposure to liability rose sharply following implementation of the 1991 Civil Rights Act and Americans with Disabilities Act in 1992. Employment discrimination lawsuits in federal courts rose from 8,273 in 1990 to 15,965 in 1994, 19,059 in 1995, and 23,152 in 1996 (Administrative Office of the U.S. Courts 2004)—a nearly threefold increase in seven years. After the Supreme Court approved mandatory arbitration in Gilmer v. Johnson/ Interstate Lane Corp. (1991), employers saw an opportunity to opt out of these lawsuits. By the late 1990s, most Fortune 1000 companies used employment arbitration (Bureau of National Affairs 2004).


It has been recognized in recent years that the occurrence of a wide variety of pharmaceuticals in the aquatic environment is chiefly due to secondary effluent from sewage treatment plants, where the residual pharmaceuticals contained may possibly be in the range of ng • L to μg • L. However, little is still known of the occurrence and behavior of pharmaceutical metabolites such as conjugates, epoxides and hydroxides in an aquatic environment. The authors developed an instrumental analytical method with liquid chromatography tandem mass spectrometry (LC/MS/MS) for the simultaneous determination of three pharmaceuticals and their five metabolites. The minimum quantifiable level of target compounds was 0.62 to 11ng • L. The developed analytical method was successfully applied to actual environmental water samples taken at a sewage treatment plant and a water purification plant located in the Tokyo metropolitan area. Seven out of eight target compounds were detected in the range of 50ng • L to 16μg • L after processing in primary sedimentation tanks in the sewage treatment plant. Six compounds were also detected in the range of 13 to 38ng • L in downstream river water. Both carbamazepine and its metabolite were persistent in groundwater and even in finished water in the water purification plant.


ABSTRACT This article documents Australia's use of border security support and humanitarian aid as border externalisations immobilising asylum seekers as far from Australia as possible. The Australian Government frames border securitisation through regionalism, as an effort to achieve a "regional solution" to asylum seeking irregular migration. Correspondingly, scholars have documented Australia's externalisations in Southeast Asia and the Pacific. However, Australia's efforts are not regionally circumscribed and this article analyses the spatial and temporal flexibility of Australia's border externalisations; Australia's strategy of targeting borderscapes of asylum seeking as they emerge and change. In doing so, the article examines how the Australian Government has assembled externalisations in South Asia, the Middle East, and North Africa. Australia's use of humanitarian aid to make places housing asylum seekers more hospitable, yet confining, to the displaced is detailed. Also analysed is Australia's border security support to source countries and countries of first asylum to immobilise asylum seekers. The article demonstrates that Australia has sought to manifest not only a territorial buffer zone in Southeast Asia, but use border externalisations in the Middle East, South Asia, and North Africa to secure places and displaced populations. This is argued to be a preventative strategy of risk management designed to preempt future asylum geographies and forge extraterritorial migration control.


In this article, a novel frequency-selective rasorber (FSR) is proposed, which provides a high-efficiency transmission band and a broadband radar cross section (RCS) reduction by hybridizing low-frequency diffusion and high-frequency absorption. The FSR comprises three layers. A broadband second-order bandpass frequency-selective surface is designed as the bottom layer, which has a reflection–transmission–reflection frequency response, and acts as an equivalent ground plane for the upper layers outside the transmission band. A circuit analog absorber and a coding metasurface are designed as the middle and top layers, respectively. They use absorption and diffusion to reduce the RCS at high- and low-frequency bands. In the coding metasurface, miniaturized and absorptive techniques are utilized to suppress the harmonic resonances. The whole FSR unit cell exhibits a cross-polarized reflection–transmission–absorption frequency response. A co-polarized transmission magnitude larger than −1.5 dB from 7.4 to 12.1 GHz and a co-polarized reflection magnitude less than −10 dB from 3.1 to 20 GHz are observed in the full-wave simulation under the normal incidence. An FSR sample with $20\times20$ unit cells is designed and measured for verification. The measurement agrees well with the simulation, and it shows a significant monostatic RCS reduction from 3.3 to 20 GHz in comparison with a metallic plane of the same size.


Backgrounds and Objectives: House dust mites and cockroaches are important indoor allergen sources causing allergic rhinitis and asthma. The aim of this study was to investigate the house dust mite and cockroach prevalence using skin prick test (SPT). Materials and Methods: In this study 407 allergic rhinitis and asthmatic patients were evaluated. All patients were tested with the aeroallergens using house dust mix, Dermatophagoides farinae, Dermatophagoides pteronyssinus and cockroach mix. Data were analyses by Statistical analysis. Results: Total number of 407 patients 212 (52%) males and 195(48%) females, age between 4 70 years, were studied. In asthmatic and allergic rhinitis, the respective positive percentages for house dust, Dermatophagoides pteronyssinus, Dermatophagoides farinae and cockroaches were 23.3%, 31.7%, 35.6% and 32.9% respectively. Total IgE level elevated in over half of allergic patients. Conclusion: A relatively high prevalence of mites and cockroach sensitivity was found in our study. These figures are is similar with other reports from hot and humid areas.


An analysis of its content and illustrations indicates that wSieci occupies a middle ground between serious opinion-shaping press and a political tabloid. Its taste for scandal is signalled first and foremost by its characteristic cover cartoons, a mix of crude simplification, brazen partisanship and unashamed xenophobia. Like other magazines with upmarket ambitions wSieci has followed the vogue for writing focused on sharply-drawn individuals. Its defiant conservatism that doesn't mince words is both a political stance and a marketing strategy. The magazine started with a big splash, but now that its price has climbed up and the novelty effect has faded, its sales have peaked.

A method of measuring changes of minority carrier concentration in a semiconductor is discussed. The method is applied to the investigation of injection in specimens of p-type lead sulphide which show transistor action. There is evidence of electron injection at both `point' metal contacts and contacts of area up to 10-4 cm2. In the latter case an additional effect is observed which is interpreted as the reverse of injection, i.e. electron extraction.


The study investigated children's conceptions of family. Participants were 120 boys and girls aged 5-12, from two Brazilian regions (Northeast and Southeast), two urban contexts (capitals and inland cities), and from upper middle and lower socioeconomic strata. Children were interviewed individually according to a semi-structured interview syllabus. The results showed that children's conceptions of who belongs to the family do not reflect cohabitation, but, possibly, the degree of companionship with other relatives (grandparents, uncles and aunts, cousins); generation was a stronger differential than gender for the definition of father's, mother's, siblings', grandfathers' and grandmothers' profiles; family was pictured as a basic need, locus of identity and belongness, but children find it difficult to define the concept. Methodological questions are discussed and directions for future research are pointed out.


In one-dimensional multiparticle Quantum Cellular Automaton (QCA), the approximation of the bosonic system by fermion (boson-fermion correspondence) can be derived in a rather simple and intriguing way, where the principle to impose zero-derivative boundary conditions of one-particle QCA is also analogously used in particle-exchange boundary conditions. As a clear cut demonstration of this approximation, we calculate the ground state of few-particle systems in a box using imaginary time evolution simulation in 2nd quantization form as well as in 1st quantization form. Moreover in this 2nd quantized form of QCA calculation, we use Time Evolving Block Decimation (TEBD) algorithm. We present this demonstration to emphasize that the TEBD is most natu-rally regarded as an approximation method to the 2nd quantized form of QCA.


Random and search-based test generators yield realistic test cases based on program APIs, but often miss structural test objectives that depend on non-trivial data structure instances; Whereas symbolic execution can precisely characterise those dependencies but does not compute method sequences to instantiate them. We present SUSHI, a high-coverage test case generator for programs with complex structured inputs. SUSHI leverages symbolic execution to generate path conditions that precisely describe the relationship between program paths and input data structures, and converts the path conditions into the fitness functions of search-based test generation problems. A solution for the search problem is a legal method sequence that instantiates the structured inputs to exercise the program paths identified by the path condition. Our experiments indicate that SUSHI can distinctively complement current automatic test generation tools.


The paper presents the experiences and perspectives of studying the Polish language as a part of the certification course "Modern polish business communication" which is taught at Kyiv National Economic University for students and economists. The course aims at studing the practical use of Polish language in business, formation of cultural competence and awareness of the functioning of Polish language in business communication situations.


Sweden is in a period of change in its establishment of a new welfare system. One of the main reasons is the political power shift from social democratic welfare regime to liberal welfare regime. This change involves, among others, a restructuring of the relationship regarding responsibility in the social welfare, between the public, private and non-government sectors. This is due to how different these welfare regimes politics are to each other.
As a result of the changes regarding new relationship, new hybrid organisations have evolved that does not belong to either the traditional public sector, the public sector or the non-government sector. Vaxjo Red Cross in Vaxjo county council is one example of these hybrid organisations that evolved from the political power shift. Vaxjo county council contracts out services to the local Red Cross district. The collaboration entails a number of requirements that must be upheld by the local Red Cross district. These requirements are different from the existing organisational culture with its values within the Red Cross. This study showed that the resulting hybrid organisation affects the local Red Cross district by creating ambiguity regarding operation, responsibilities and values which more or less affect users, the employees and the voluntaries. It also shows the importance to find this new relationship regarding, among other things, responsibility.
The purpose of this paper was to examine the impact of outsourcing between Vaxjo County Council and the local Red Cross district from the perspective of the Red Cross organisation in Vaxjo. The study was based on semi-structured interviews with representatives from various stakeholder groups, written information material about the local Red Cross district in Vaxjo and local government legislation regulating contributions to the Red Cross.


There is complex electromagnetic interference in the substation. In order to improve detection accuracy, a digital lock-in amplifier is used in the detection of the grounding grid. This paper introduces the principle of non-destructive testing of grounding grid based on electromagnetic method. Firstly, the distribution characteristics of surface magnetic induction intensity at different frequencies are obtained by CDEGS simulation. At the same time, it describes the principle and structure of an orthogonal vector type digital lock-in amplifier in detail. In order to realize the high-precision grounding grid detection system, the hardware circuit of the digital lock-in amplifier is designed by FPGA and analog-to-digital converter. The digital lock-in amplifier algorithm is implemented in the FPGA. Finally, the digital lock-in amplifier is tested. The test results show that when the signal-to-noise ratio of the signal to be tested is −20 dB, the signal amplitude measurement error is less than 3%. The designed digital lock-in amplifier is applied to the actual grounding grid detection, and the topology and corrosion of the grounding network can be detected. Therefore, the digital lock-in amplifier can be effectively applied to non-destructive testing of grounding grid.

Prediabetes (preT2D) is a major U.S. public health concern, as over 84 million adults are at greater risk of cardiovascular disease and progression to type 2 diabetes (T2D). Abnormal glucose, BMI, blood pressure, and blood lipids are risk factors for progression to T2D. The purpose of this single-arm prospective longitudinal investigation was to assess change in risk factors after one year of treatment with a continuous remote care model utilizing nutritional ketosis, behavior change, and support from a health coach, medical provider, and peers provided via an online clinic. Patients with preT2D enrolled (n=116); at 1 year, 95 participants (82%) remained active. Results are reported for participants with measurements completed at 1 year and baseline; n varied across measures (range: 77-95). Changes from baseline to 1 year included: weight -13.1±9.5 kg (from 110.6±23.5 kg, p 2 (from 38.9 kg/m 2 , p 7% body weight. At 1 year, 51.1% (45/88) participants achieved fasting glucose These results demonstrate that patients with preT2D can be supported remotely with this continuous care model to improve risk factors associated with progression of preT2D to T2D. Ongoing research will evaluate the continued sustainability of this intervention and prevention of T2D. Disclosure A. McKenzie: Employee; Self; Virta Health Corp..

In recent years, the subsidy policy of new energy vehicles (NEVs) has promoted the vigorous development of China's NEV industry. In the past, scholars tended to focus on consumers' reactions to subsidy policies for NEVs, while attention to the reaction of investors is relatively scarce, especially in the context of major public emergencies. Based on the event study method, this study empirically tested the reaction mode of investors of NEV enterprises to China's program of retrogressive subsidies (PRS) in the context of COVID-19 pandemic and discussed the differences in investors' reactions under different enterprise attributes (i.e., whether listed on the Shanghai Stock Exchange, whether located in a first-tier city, whether belonging to state-owned enterprises, and whether belonging to the upstream NEV industry). Our research results provide a reference for the strategic management practices of NEV enterprises and their investors.

Fabrication of enhancement-mode high electron mobility transistors on AlGaN/GaN heterostructures grown on sapphire substrates is reported.These devices with 1.2μm gate-length,4mm space between source and drain,and 15nm recessed-gate depth exhibit a maximum drain current of 332mA/mm at 3V,a maximum transconductance of 221mS/mm,a threshold voltage of 0.57V, ft of 5.2GHz,and fmax of 9.3GHz.A dielectric layer formed unintentionally during recessed-gate etching is confirmed by contrasting the Schottky I-V characteristics of pre-etching and post-etching.The frequency characteristics and subthreshold characteristics of the devices are studied in detail.


Objectives: In this study, MissForest algorithm is used to analyze the impact of missing data. Statistical Analysis: For categorical dataset, MissForest package is used to impute various missing values and tested with missing data incrementally, first with 5% missing attributes of the records from the original dataset then with 10% and so on. Findings: The Proportion of Falsely Classified (PFC) is computed for categorical dataset. Since the good performance of MissForest leads to a value close to zero and bad performance to a value around one, the performance measured for the Nursery dataset is quite good. Application: This approach has good effect when the ratio of missing data is low. Missforest algorithm can be used for numerical or categorical data. The results are improved for continuous data.

This research work involving spatial objects, that are directly visible from query points. In this article, presenting the environment of spatial data mining and formulate the visible k nearest neighbor (VkNN) query solutions as incremental algorithm with two variants differing in how to prune objects during the search process. One variant applies visibility pruning only to objects, whereas the other variant applies visibility pruning to index nodes as well. Our implementation results show that the latter outperforms the former. We further propose the aggregate VkNN query, which finds the visible k nearest objects to a set of query points based on an aggregate distance function. two approaches to processing the aggregate VkNN query. One accesses the database via multiple VkNN queries, whereas the other issues an aggregate k nearest neighbor query to retrieve objects from the database and then rerank the results based on the aggregate visible distance metric, with extensive experiments.


New alkene-based anti-relaxation coating of alkali metal vapor cell demonstrated up to 10 times longer relaxation time then the same time for classical alkane-based coating. In this paper the interaction of Cs vapor with the surface of the alkene in vacuum is studied by optical Raman spectroscopy. Isomerization of alkene (double bound of C=C moving to center) was found.


The present study was performed to determine if chronic administration of the PDGF receptor antagonist, imatinib mesylate, prevents the augmentation of urinary ANG II excretion that occurs in Cyp1a1‐Ren2 transgenic rats with ANG II‐dependent malignant hypertension. Male Cyp1a1‐Ren2 rats (n=6/group) were induced to develop malignant hypertension by dietary administration of indole‐3‐carbinol (I3C, 0.3% wt/wt) for 10 days. One group was chronically treated with imatinib mesylate by oral gavage (60 mg/kg/d) starting 3 days before initiating I3C induction and maintained on imatinib for the duration of the study. Systolic blood pressures (SBP) were measured daily by tail‐cuff plethysmography. Rats were placed in metabolic cages for measurement of 24‐hour urine output and urinary protein and ANG II excretion. Dietary I3C resulted in pronounced increases in SBP (152±6 to 209±6 mmHg, P<0.001) and urine output (8.5±0.7 to 60±5 ml/day, P<0.001), marked proteinuria (26.8±3.0 to 72.2±11.8 mg/day, P<0.01), and augmented urinary ANG II excretion (448±12 to 987±119 fmol/hr, P<0.05). Chronic imatinib administration did not prevent the development of hypertension (204±3 vs. 157±8 mmHg, P<0.001) or the increase in urine flow (61.8±5.0 vs. 8.5±0.6 ml/day, P<0.001), but prevented the I3C‐induced increases in proteinuria (21.8±2.2 vs. 21.8±0.8 mg/day) and urinary ANG II excretion (263±30 vs. 492±43 fmol/hr). The present findings demonstrate that PDGF receptor antagonism with imatinib mesylate prevents the marked proteinuria and augmented urinary ANG II excretion independent of changes in blood pressure that occur in Cyp1a1‐Ren2 rats with ANG II‐dependent malignant hypertension.

Coastal areas are considered as the most valuable parts of many countries' territories, either with respect to their natural and environmental qualities or with regard to the their potential for national socio-economic development. Therefore, it is not surprising that population has always been attracted to these areas. Trends in the European coastal zone showed that the growth rate of artificial surfaces was about 1/3 faster than inland. For this reason one of Europe ́s main concerns is the changes in land cover and population in the coastal areas. According to the EEA 2006 Coastal Report at European level more than 2 720 km2 of agricultural land and semi-natural and natural land were lost predominantly to artificial surfaces, spreading 190 km2 per year between the 1990-2000 periods. One of the highest increases in artificial surfaces (20-35%) has been observed in the coastal zones of Spain [1]. Due to the irreversible nature of land cover change from natural to urban and infrastructure development, these changes are seen as one of the main threats to the sustainability of coastal zones. On the other hand the 2009 Spanish Environmental Profile shows that 22,6% of the 1 km coastline represent artificial surfaces, 10 times more than inland. Artificial land consumption has double from 1956 to 1990 period from 6,3 Ha to 12,5 Ha, and triple from 1990 to 2006 period to up to 35,37Ha every 1 000 inhabitants [2].


This paper studies propositional proof systems in which lines are sequents of decision trees or branching programs — deterministic and nondeterministic. The systems LDT and LNDT are propositional proof systems in which lines represent deterministic or non-deterministic decision trees. Branching programs are modeled as decision dags. Adding extension to LDT and LNDT gives systems eLDT and eLNDT in which lines represent deterministic and non-deterministic branching programs, respectively. Deterministic and non-deterministic branching programs correspond to log-space (L) and nondeterministic log-space (NL). Thus the systems eLDT and eLNDT are propositional proof systems that reason with (nonuniform) L and NL properties. The main results of the paper are simulation and non-simulation results for tree-like and dag-like proofs in the systems LDT, LNDT, eLDT, and eLNDT.

Optical Doppler tomography (ODT) is an imaging technique, which uses the Doppler shift observed in the spectrum of backscattered light to calculate the pixel values of the sample being imaged. Using this technique, one can obtain an image that contains structural information and an image that contains the location of movement in the image. As data acquisition rates for ODT systems become faster, the need arises for faster algorithms with which to process this data and create the structural and velocity images. However, since this area is very young, the signal processing aspects of ODT have been largely unexplored. The goal of this project is to develop efficient algorithms for producing velocity image in ODT systems. In this paper, we propose researching several methods of making the signal processing aspects of ODT system more efficient.


The new Road Safety Manual (RSM) is designed to help countries at every stage of infrastructure development to fulfill road safety objectives. It is aligned with key pillars for the United Nationals Decade of Action for Road Safety 2011-2020: Pillar 1: Road Safety Management; Pillar 2: Safer Roads and Mobility; Pillar 4: Safer Road Users. This comprehensive resource builds on the broad range of knowledge and experience provided by PIARC in the first edition. It includes new thinking on road safety and offers a clear argument on why adopting a Safe System approach is crucial for your country. The Safe System approach aims for a more forgiving road system that takes human fallibility and vulnerability into account. Under the Safe System approach, everyone (public agencies, automobile manufacturers, road users, enforcement officials, and others) must share the responsibility for road safety outcomes. The manual is split into three parts and can be downloaded in chapters. Key principles for each of the topics are included and discussed in the sections, with case studies and links to detailed technical material and other references.


Global challenges research brings with it the challenge of integrating diverse cultural and disciplinary perspectives in the service of addressing persistent and complex problems. In fragile and resource poor contexts this also brings with it a swathe of operational, legal and logistic challenges which can generate ethical conflicts. A scoping review is needed to identify key issues of research ethics and integrity, as well as strategies that have been brought to bear in an effort to resolve them. This protocol followed Prisma guidelines for Scoping Reviews (Prisma-ScR) and provides details of the review scope and parameters.


Arterial blood-gases and lung volumes were measured in 48 patients before and after upper abdominal surgery. There was no significant difference between the results of 25 patients ventilated with oxygen and nitrogen during anaesthesia compared with a comparable group which received oxygen and nitrous oxide.


In the recently issued third volume of his monumental work on ChrisJian Missions and Social Progress, Dr. J. S. Dennis deals with certain problems that are of interest, not onlv from the missionary point of view, but also from that of biblical study anil religious education in general. Dr. Dennis is a thorough believer in the necessity both of a religious element in education and of an educational element in religion, and in particular in missionary work. On the former point, speaking of the system of education introduced into India by the English government, he savs: The absence of all religious instruction which is carried to the extent of absolute neutrality, is, moreover, a great defect when the higher welfare of society is considered, and goes far to account for much that is disappointing in the outcome of Indian state education. This is freely acknowledged even by many who regard religious neutrality as the only proper attitude for the government to take in an educational system for India.


Walker et al 1 rightly concluded that the bacille Calmette–Guerin (BCG) vaccination does have a noteworthy protective effect against tuberculous meningitis (TBM). However, it might be worth pointing out that the analysis does not include a few recent studies, which lead to the same conclusion based on robust …

The material of the study are the results of examination of 40 sportswomen and 47 sportsmen who train three tem sports (basketball, volleyball and handball), of the age between 18 and 25. The research consisted of two tests evaluating the maximal anaerobic power – MAP (Georgescu's test and Vandewalle's test) and running test 10 x 3 m. What results from the analysis, the test meets the expectations of solidity and accuracy and its results can function as an indicator of special motor fitness of sport games players.


We describe an experiment to visually quantify the accuracy of the simulation of the color and color-difference of surface samples on a CRT display unit. A gray-scale-anchored, magnitude-estimation experiment was performed to assess the absolute quality of the simulations and a forced-choice, paired-comparisons experiment was performed to assess the relative quality of the simulations. Results indicate that an average color difference for overall simulation accuracy can be under 3.0 CIELAB color-difference units for highcolor-temperature sources, and slightly worse for low-colortemperature sources. All simulations were well under the 6 to 12 unit differences reported for typical color reproduction. Possible reasons for the residual color differences between the current simulations and the theoretical limit are presented.


A total of 169 cucurbit accessions includes 34 accessions of pumpkin (Cucurbita moschata), 69 accessions of angled loofah (Luffa acutangula) and 66 accessions of watermelon (Citrullus lanatus) obtained from Clover Seed Ltd. (Thailand) were screened for resistance to Cucumber mosaic virus (CMV) isolate NK10 (CMV-NK10), Papaya ringspot virus (PRSV) isolate Cu014 (PRSV-Cu014) and Zucchini yellow mosaic virus (ZYMV) isolate Cu012 (ZYMV-Cu012) under greenhouse conditions. Mechanical inoculation of the first and second true leaves was done by rubbing with a mixture of virus inoculum and carborundum. Four weeks after inoculation, all plants were evaluated visually for symptoms of virus infection and tested by Indirect plate trapped antigen ELISA (indirect PTA-ELISA) to determine virus presence in upper, non-inoculated leaf tissue. Disease rating based on percent of infected plants classified accessions as immune, resistant, moderate resistant, moderate susceptible and susceptible. Twelve accessions of angled loofah were immune to our isolates of all three viruses. Almost all tested accessions were immune to CMV-NK10 include eighteen accessions of pumpkin, fifty accessions of angled loofah and sixty six accessions of watermelon. Seventeen and five accessions of angled loofah and watermelon, respectively, were immune to PRSV-Cu014. Sixty six accessions of angled loofah were immune to ZYMV-Cu012. The immune accessions identified in this study may prove to be significant new sources of CMV, PRSV and ZYMV resistance for breeding programs for cultivar development.

Na-montmorillonite was acted as a kind of additive for fumed nano-SiO2 sulfuric gel electrolyte,by this way,a series of gelled electrolyte with different content of MMT were prepared in 1.28 % sulfuric acid solution and fumed nano-SiO2 content was 4 %.Rotary viscometer testing indicated that the viscosity of gelled electrolyte could be decreased under larger rotation rate,while increased under small rotation rate by adding appropriate small amount ofMMT.When the content ofMMT was above 0.3 phr,MMT would act as thickening agent.Cyclic voltammetry(CV) and impedance spectroscopy(EIS) analysis indicated that MMT could reduce the electrode polarization degree and electrode electrolyte interface resistance,increase the electrode reaction current and power with the improvement ofutilization ratioofelectrode activematerial.


The silverleaf whitefly MEAM1 (Bemisia tabaci) Gennadius (Hemiptera: Aleyrodidae), the cowpea aphid (Aphis craccivora Koch), the green peach aphid (Myzus persicae Sulzer) and the melon aphid (Aphis gossypii Glover) Hemiptera: Aphididae are major insect pests of squash (Cucurbita pepo L.), causing significant yield losses of up to 80% in Florida. We hypothesized that intercropping African marigold (Tagetes erecta L.) and cowpea (Vigna unguiculata L. Walp.) with zucchini squash will encourage an abundance of beneficial arthropods and increase cultural and biological control against these key insect pests by significantly reducing their populations and consequently improve yields. In a 2‐year field experiment, five treatments were evaluated in a randomized complete block design consisting of four replicates. Three diversified cropping treatments were implemented: (1) intercropping squash with marigold, (2) intercropping squash with cowpea, (3) intercropping squash with marigold and cowpea (mixed). These treatments were compared with an organic grower standard insecticide, (4) M‐Pede (potassium salts of naturally derived fatty acids) sprayed on monocropped squash and (5) monocropped squash with no pest management (control). Results indicated that squash intercropped with marigolds accounted for the highest marketable yields. Squash intercropped with cowpea had marginally high yields but attracted the highest densities of aphids. M‐Pede did not increase squash yields, but reduced aphids, whiteflies and associated squash silverleaf (SSL) disorder ratings and showed no deleterious effect on populations of natural enemies. We conclude that a mixture of marigold and cowpea could be used to suppress pests by increasing beneficial arthropod diversity while enhancing marketable yields of organic squash. M‐Pede could be used as a last resort when experiencing high hemipteran pressure.


Abstruct'lkansport properties of ungated Si/Sil --z Ge, are studied by an ensemble Monte Carlo technique. The device performance is studied with a quantum hydrodynamic equation method using the Monte Carlo results. The phonon-scatteringlimited mobility is enhanced over bulk Si, and is found to reach 23000 cm2/Vs at 77 K and 4000 cm2Ns at 300 K. The saturation velocity is increased slightly compared with the bulk value at both temperatures. A significant velocity overshoot, several times larger than the saturation velocity, is also found. In a typical modulation-doped field-effect-transistor, the calculated transconductance for a 0.18 pm gate device is found to be 300 mS/mm at 300 K. Velocity overshoot in the strained Si channel is observed, and is an important contribution to the transconductance. The inclusion of the quantum correction increases the total current by as much as 15%.


Abstract A particularly intense case of western Atlantic baroclinic cyclogenesis was investigated in this study. Specifically, the roles of latent heat of condensation and surface friction were examined from the potential vorticity or "PV thinking" perspective. The methodology used for this study involves three key components: 1) a full-physics mesoscale model, which provides a continuous and dynamically consistent dataset and provides full user control over physical processes; 2) a partitioned PV integration, which temporally integrates the accumulation of PV due to various physical processes in the model's Eulerian framework: and 3) the piecewise inversion method of Davis and Emanuel, which calculates the balanced wind and mass field associated with particular PV anomalies. Potential vorticity features obtained through the partitioned integration technique were inverted to yield their direct contributions to the total circulation. In addition, sensitivity studies were carried out to determine the overal...


The depleted uranium (DU) inventory in the U.S. exceeds 500,000 metric tons (tonnes). A large portion of the U.S. inventory of DU can be used in the fabrication of nuclear shielding for the storage, transport, and disposal of spent nuclear fuels (SNF). Oak Ridge National Laboratory (ORNL) researchers analyzed the production of this shielding material based on work done at the Idaho National Laboratory (INL), measured the DUO2-aggregates' physical properties and chemical durability, estimated capital and production costs of SNF casks using DU concrete (DUCRETE TM ), and studied the shielding properties of this material when used for SNF cask manufacturing. The All-Russian Scientific-Research Institute of Experimental Physics (VNIINM) Russian researchers have also developed DUCRETE to fabricate spent fuel casks. Essentially, the VNIINM process has modified the production of concrete aggregate and as a result of these studies has proposed a simpler process for spent fuel cask manufacturing. This paper describes (a) the process derived from the INL studies, (b) the results of the shielding analysis, (c) the concrete aggregate process developed at the VNIINM, and (d) economic analysis of incorporating the Russian modifications into the process and fabrication technologies previously analyzed by ORNL. Results show reduced cask weight and size when using the DUCRETE material to replace the conventional concrete. The cost analysis performed in this study also indicated a reduction in SNF cask overall production cost of ~10% by adding the process modifications suggested by researchers of VNIINM.


Causes for stenosis of the left internal mammary artery (LIMA) graft are flow competition from the native vessel, narrowing at the anastomotic sites, atherosclerosis, fixed kinks within the graft, smooth tubular stenosis, dissection, and spasm (1, 2). Acute thrombosis of the LIMA, however, is rare and usually presents in the early post-operative period due to inadequate anti-thrombotic treatment or incompetent surgical technique (3-5). In this report, we represent a case of acute thrombotic occlusion of the LIMA, 14 years after coronary artery bypass grafting surgery (CABG), presenting with acute myocardial infarction (AMI), and managed with primary percutaneous coronary intervention (PCI).

Cloud computing finds applications in different industries, providing various services and data storage capabilities. While data stored in the cloud can be retrieved based on user requests, data security remains a primary concern. To address these security concerns, a proposed system employs the combined strength of the Triple Data Encryption Standard (AES) and Blowfish algorithms. The lack of robust and efficient secure file storage systems in cloud computing poses significant risks to data confidentiality and integrity.Existing solutions often lack strong encryption mechanisms and reliable server-side encryption and decryption capabilities. This research aims to develop a secure file storage system that leverages server encryption and decryption techniques to ensure data confidentiality, integrity, and access control in cloud environments. The objective is to design a system that effectively protects sensitive files during storage, transmission, and processing, while maintaining efficient data access and retrieval for authorized users. Key Words: Server-Side Encryption, Secure Key Storage Decryption, Encryption, Secure File Storage, Blowfish

We focus on the problem of manifold estimation: given a set of observations sampled close to some unknown submanifold M , one wants to recover information about the geometry of M. Minimax estimators which have been proposed so far all depend crucially on the a priori knowledge of some parameters quantifying the regularity of M (such as its reach), whereas those quantities will be unknown in practice. Our contribution to the matter is twofold: first, we introduce a one-parameter family of manifold estimators (M t) t≥0 , and show that for some choice of t (depending on the regularity parameters), the corresponding estimator is minimax on the class of models of C 2 manifolds introduced in [Genovese et al., Manifold estimation and singular deconvolution under Hausdorff loss]. Second, we propose a completely data-driven selection procedure for the parameter t, leading to a minimax adaptive manifold estimator on this class of models. This selection procedure actually allows to recover the sample rate of the set of observations, and can therefore be used as an hyperparameter in other settings, such as tangent space estimation.


Rosa foetida is a dense, erect shrub with bright yellow or scarlet flowers with a yellowish reverse petal. It is most abundant in South West Asia. In Iran R. foetida occurs mainly in the mountainous North and West regions. The species is the origin of the strong yellow color in hybrid roses, which was introduced into modern cultivars in 1900 through a single species hybridization event. In this study we have used 10 microsatellite markers to determine diversity in Rosa foetida accessions collected across Iran. To our surprise, nearly all samples collected were of the same genotype, even when collected at different sites. Only four different genotypes have been detected in total. The results are discussed in relation to breeding system, human influence and overall gene pool status


Abstract New poly(maleimide-ethers) containing chlorine and fluorine were synthesized and characterized. They were prepared by reacting bisdichloromaleimides with 4,4′-(hexafluoroisopropylidene)diphenol. Polymers were characterized by inherent viscosity measurements and infrared (IR) spectroscopy. Thermal characterization of monomers and polymers were accomplished by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and differential thermogravimetry (DTG). GPC was employed for characterization of polymer Illb. In addition, the thermal stability of the polymers was evaluated by isothermal gravimetric analysis (IGA). The properties of these polymers are discussed and compared with polymers derived from bisphenol A.

Permutation polynomials are an interesting subject of mathematics and have applications in other areas of mathematics and engineering. In this paper, we present two classes of explicit permutation polynomials over $\mathbb{F}_q$ from two piecewise functions.


Language is the carrier of culture. Different national cultures give different languages a different cultural connotation and the difference in national cultures leads to nonequivalence between different languages, which causes difficulty in the translation between and two languages. The EnglishChinese nonequivalence is often seen in the zero of equivalence and the conflict in the meaning of words.


make any general claims about the form of optimal decision regions and, even in the case of Example (1), the results are mainly concerned with the level of average costs which can be achieved by relatively simple policies. For large values of the parameter b, it turns out that the sampling cost is prohibitive so the optimal decision region B is empty and the corresponding degenerate problem is easily solved. Further progress is based on evaluating policies in which the sampling rate is chosen to maintain a constant value of the variance v. This effectively reduces Equation (3) to an ordinary differential equation and its solution provides attainable values of the average cost. Finally, a lower bound on the minimum average cost can be found by the device of reducing the specified cost functions in such a way that the modified free boundary problem can be solved explicitly. These ad hoc results provide some support for a rather tenuous general theory. They also indicate that a deeper mathematical study of this kind of decision problem may prove useful as well as interesting.

Mesenchymal stem cells (MSCs)-based therapy shows promise to treat cartilage degeneration, which lacks the regenerative ability in osteoarthritic patients. Differentiation of MSCs into chondrocytes mainly uses a specific differentiation medium. However, biomechanical induction can direct the chondrogenesis of MSCs without the chondrogenic differentiation medium, particularly with micropattern. Micropattern provides physical and mechanical induction to the cell hence facilitates signal transduction that leads to cell differentiation. Human Wharton's jelly MSCs (HWJ-MSCs) were used as the material due to their low risk of allogenic transplant rejection. In this study, biomechanical induction was done using striped micropatterns of 500 µm and 1000 µm width with spidroin concentrations of 50 µg/ml and 10 mg/ml to determine the effect of cell density on HWJ-MSCs chondrogenesis. This study aimed to develop a non-toxic spider silk protein (spidroin) bioink from Argiope appensa as a biomaterial, produce micropattern using microcontact printing, and determine micropattern width and bioink concentration effect on chondrogenic differentiation markers, specifically glycosaminoglycan (GAG) and collagen type II. GAG content was measured through colorimetric analysis with Alcian Blue, whereas collagen type II expression was visualized using immunocytochemistry. MTT assay showed that the spidroin bioink was non-toxic and improved the viability of HWJ-MSCs. The combination of micropattern 1000 µm and spidroin 50 µg/ml produced the highest GAG content. The expression of collagen type II was detected in all treatment groups. Micropattern 1000 µm was able to induce chondrogenesis by increasing cell density, which played an essential role in the condensation step of chondrogenic differentiation. Spidroin 50 µg/ml was hypothesized to induce chondrogenesis via integrin signaling, influenced by cell spreading and contractility. This study concludes that based on GAG content, the optimal condition to induce chondrogenesis was using a micropattern of 1000 µm width and spidroin concentration of 50 µg/ml.


Nanoparticles (NP) are widely used for domestic, industrial and medical applications. However, because of their nano-size they can easily penetrate cellular membranes, causing increased damage to the mitochondrial and genomic DNA. NPs also were reported to induce inflammation, cell apoptosis and oxidative stress.
 In this research, the effect of gold NPs on growth, reproduction, fecundity, life span as well as induction of immune responses in Caenorhabditis elegans (C. elegans) are studied. The nematode has proven to be the best model to study effects difficult to explore in humans. The adr-2 mutant C. elegans is highly susceptible to environmental toxicity and offer sensitive bioassays to study the impacts of gold NPs on the worm. Two groups of adr-2 mutant C. elegans were grown. One group was exposed to gold NPs and the responses were analyzed and compared to the control group without nanoparticles. The two groups of C. elegans were observed over 2 months, thrashes were counted and the experiment was repeated several times. Findings showed that the thrash count for mutant strains decreases. Thus, at 0 minutes the thrash count was 55, reached 45 at two minutes, and decreased to 30 at four minutes. The other environmental contributors to this effect are under evaluation. The preliminary results showed that both groups had no visible changes. Nematodes were imaged using confocal differential interference contrast (DIC) microscopy. Several different pathways (p38 MAPK (PMK-1) and insulin like receptors (DAF-2)) could be activated to contribute to stress resistance to the NPs. Mutant strains of C. elegans for these receptors need to be tested to get a better understanding of the effect of the gold NPs on the immune responses.

With the continuous demand for fossil fuel and advancement in technology, the unconventional petroleum resources have come into limelight. The Bakken-Three Forks Petroleum System consisting of carbonate and clastic sediments in the Williston basin is an unconventional petroleum accumulation with a technically recoverable oil resources of 7.38 billion barrels. However, understanding the relationship between oil saturation with respect to source rock maturity and pore size distribution in the reservoir lithofacies are challenging. Four wells from Ambrose, West Ambrose and Colgan fields within an area of 65 sq. miles will be utilized for this study. Preliminary physical core description and wireline logs were used to identify lithofacies and correlate them across all wells. Seven lithofacies were identified in the Three Forks Formation. They are: 1) Massive mudstone, 2) Massive dolostone 3) Laminated mudstone and dolostone 4) Mottled dolostone 5) Mottled mudstone 6) Brecciated mudstone and 7) Conglomerated mudstone. The source rock maturity will be evaluated with the Weatherford SRA TOC-TPH method by running a programmed pyrolysis analysis on crushed samples taken at an interval of 1ft through the lower Bakken Formation. Pyrolysis analysis provides information on geochemical parameters of source rock such as TOC, S1, S2, S3, Tmax, HI, OI and PI. These parameters indicates thermal maturity, organic richness and kerogene types. The bulk volume of each lithofacies will be precisely measured with a 3D laser scanner while pore volumes will be measure with a helium porosimeter before saturating in a NaCl brine solution at 100 psi for 30 days. Porosity analysis and pore sizes distribution will be acquired from NMR transverse relaxation (T2) analysis with Oxford Instruments GeoSpec2 core analyzer coupled with Green Imaging Technology software. Nuclear Magnetic Resonance relaxation time results will be used to estimate pore size distributions and classify them into micropores, mesopores and macropores. The reservoir lithofacies within the study area are expected to have different T2 relaxation time based on varying pore geometry, clay content and grain sizes. Integrating published T2 cut off values and results from this study will be used to establish a relationship between pore size distribution and fluid saturation.

on MIT assembled by David Kaiser's edited work, Becoming MIT: Moments of Decision (MIT Press, 2010). If the culture described so carefully is wider than MIT, what are the mechanisms by which influence is spread, and do these have any relationship to the contents of the culture? The author concludes with the reflection that synthetic biology will soon cease to be remarkable. We may be grateful that scholars used the period when its ambitions were still uncanny to remark on their implications. As the author concludes, the objects of synthetic biology redefine life itself.


This paper is an overview of the research at MIT on MEMS liquid bipropellant rocket engines. Sized to provide 10-15N of thrust at a thrust-to-weight ratio of about 1000:1, these engines have specific impulse approaching the theoretical value achievable for the propellants. The motivation for this effort is twofold: first, to explore the high power density boundaries of microrocket propulsion systems, and second, to demonstrate a useful propulsion capability. The basic approach is to engineer miniature versions of rocket engine subsystems – thrust chamber, exhaust nozzle, turbopumps, valves – redesigned to be compatible with conventional MEMS silicon processing technology. Work has also been done to characterize the thermo-fluid behavior of rocket propellants at conditions representative of the MEMS rocket engine operating environment.


Several methods of constructing systematic t-error correcting/all unidirectional error-detecting codes are described. These codes can be constructed by adding a tail to a linear t-error correcting code, but other constructions presented are more of an ad hoc nature. These codes will often be found as suitably chosen subsets of nonsystematic tEC/AUED codes. Further bounds on the word length of systematic tEC/AUED codes are derived, and extensive tables are given. >


Science, Technology, Engineering, Mathematics, abbreviated as STEM is a very promising field and its popularity is increasing due to its benefits in the modern world of globalization and modernization. Science and mathematics are basics of the technological developments going on in the world. In order to continue with these developments, the children should be motivated to learn STEM from early school days. The minds of small kids are like a sponge and they are able to grasp everything quickly. STEM education should be encouraged from the childhood so that children like it and continue with it for higher education. This chapter discusses some of the challenges observed while encouraging children to learn STEM at early age and also tries to list out some solutions for it.

The incidence of inguinal hernias varies between 3% and 8%. The high incidence of this disease makes inguinal hernia repair one of the most common surgical procedures. Although various techniques are reported for repair, the back wall repair made by using the patient's own tissues has been seen to be insufficient particularly in giant and recurrent hernias. Thus, techniques using prosthetic material have been created. Inguinal hernia surgery has gained a different dimension with the application of laparoscopic surgery in inguinal hernia repairs. Furthermore, these laparoscopic methods have become accepted all over the world in a short time and successfully applied in many centers. In laparoscopic inguinal hernia repair, the defect in the inguinal region and all potential hernia areas are supported with a prosthetic material without causing tension. Inguinal hernia repairs have several advantages. For instance, it is a laparoscopic approach, the postoperative pain and ABSTRACT


This paper describes a new approach to the synthesis of PtAg alloy nanostructures rich in Pt at the surface through a selective electrochemical dissolution of Ag from PtAg alloy nanoparticles that are made from platinum acetylacetonate, Pt(acac)2, and silver stearate, Ag(St). The surface and bulk compositions, size, and architecture of these heterogeneous nanostructures are controlled synergistically by changing the upper limits of cycling potentials in perchloric acid (HClO4) aqueous solution to dissolve Ag deterministically. The structures and elemental distributions of Ag and Pt in the resulting heterogeneous nanoparticles are characterized by high‐resolution transmission electron microscopy (HR‐TEM), high‐angle annular dark‐field scanning transmission electron microscopy (HAADF‐STEM) and energy‐dispersive X‐ray (EDX). These Pt‐surface rich PtAg nanostructures exhibit much higher activity than Pt nanoparticles as electrocatalysts in formic acid oxidation reaction (FAOR).


The historical prerequisites for the formation of migration waves of the population of Ukraine are analyzed as follows: the first wave («old migration» – the second half of the nineteenth century with the predominance of migration of workers); the second wave («new migration» – the end of the nineteenth – the first half of the twentieth century. with the predominance of migration of poor peasantry); the third wave («political» – after World War II until the 1980s, with a predominance of low-skilled workers and intellectuals); the fourth wave («migrant workers», since the mid-90s of the twentieth century.). It is noted that the fifth, «intellectual» wave (since the 2010s) can be transformed into a «corporate», which provides for the withdrawal of business abroad in the context of increased tax burden in Ukraine. The likelihood of a «corporate» wave also strengthens the stimulating policy of European countries to attract businesses that offer stable economic conditions. Ukraine's place on the global migration map confirming its inclusion in the international space as a democratic and legal State has been studied. The number of international migrants from Ukraine is gradually increasing, reaching 6.1 million people in 2020, but the problem of such dynamics is exacerbated by the declining dynamics of immigration and threatening depopulation processes: in 2020, the share of international expats in the population reached 11.9%, when in 1990 it was equal to 10.8%. Studying the migration processes of the population of Ukraine, scientists and experts often focus on the problem of human losses due to emigration. However, the modern world, even during the pandemic, is developing in the context of globalization. Many countries have an effective policy of attracting human potential, thus ensuring positive development dynamics. Therefore, the authorities of Ukraine are forced to intensify the State regulation of migration processes, guided by the consequences of their impact on socio-economic development.


Environment has created creative and well-designed ways for developing nanomaterials having intriguing properties. Nanotechnology is having hope to open new avenues to combat and avert diseases using atomic-level fabrication of materials. Herein, we demonstrate the fabrication of silver nanoparticles using aqueous extract of weaver ant's (Oecophylla smaragdina) nest and its characterization using valuable techniques such as ultraviolet-visible spectroscopy, X-ray diffraction analysis, scanning electron microscopy analysis, Fourier-transform infrared spectroscopy, and atomic force microscopy analysis. Cytotoxicity of newly synthesized silver nanoparticles was analyzed using the Vero cells. By analyzing the results critically, it is hypothesized that synthesis and stabilization of silver nanoparticles were achieved using the molecules present in the aqueous extract of O. smaragdina nest.

Gas clathrates contain more of the earth's hydrocarbon resources than all other forms combined, and therefore provide both a source of energy and an option for carbon sequestration. We performed a gas replacement reaction in hydroquinone clathrate in a high pressure cell, first creating a CO2 clathrate and then replacing the CO2 with CH4, and observed the spectra continuously throughout both reactions with terahertz time domain spectroscopy. The absorbance spectra show the initial enclathration phase transition and the replacement reaction from CO2 clathrate to CH4 clathrate.


ABSTRACT Expansion of shrub species is widely reported in northern regions, although its extent varies across the landscape. In subarctic Québec (Canada), where dwarf birch (Betula glandulosa Michx) is the main species responsible for shrub expansion, little is known about the causes and consequences of this phenomenon. This study aims to identify the drivers of dwarf birch densification heterogeneity at the landscape level and to evaluate its influence on other shrub species. We used model selection with Akaike's information criterion to rank ecologically relevant models including topographic, historical and edaphic variables. The influence of dwarf birch densification was evaluated through regression analysis. We found that the best model explaining the heterogeneity in dwarf birch densification in western Nunavik includes factors related to both historical conditions (initial shrub cover, time elapsed since last wildfire) and topography (type of environment). Among these factors, only the initial shrub cover had a significant positive influence on the shrub densification. Increase in dwarf birch cover was found to negatively influence the cover of other shrub species. However, no relation was found between dwarf birch densification and other shrub species richness, suggesting that the densification did not yet lead to the exclusion of less competitive species.


An out-of-yoke irradiation setup using the proton beam from a cyclotron that ordinary produces radioisotopes for positron emission tomography (PET) has been developed, characterized, calibrated and validated. The current from a 20 μm thick aluminum transmission foil is readout by home-made transimpedance electronics, providing online dose information. The main monitoring variables, delivered in real-time, include beam current, integrated charge and dose rate. Hence the dose and integrated current delivered at a given instant to an experimental setup can be computer-controlled with a shutter. In this work, we report on experimental results and Geant4 simulations of a setup which exploits for the first time the 18 MeV proton beam from a PET cyclotron to irradiate a selected region of a target using the developed irradiation system. By using this system, we are able to deliver a homogeneous beam on targets with 18 mm diameter, allowing to achieve the controlled irradiation of cell cultures located in biological multi-well dishes of 16 mm diameter. We found that the magnetic field applied inside the cyclotron plays a major role for achieving the referred to homogeneity. The quasi-Gaussian curve obtained by scanning the magnet current and measuring the corresponding dose rate must be measured before any irradiation procedure, with the shutter closed. At the optimum magnet current, which corresponds to the center of the Gaussian, a homogenous dose is observed over the whole target area. Making use of a rotating disk with a slit of 0.5 mm at a radius of 150 mm, we could measure dose rates on target ranging from 500 mGy/s down to 5 mGy/s. For validating the developed irradiation setup, several Gafchromic® EBT2 films were exposed to different values of dose. The absolute dose in the irradiated films were assessed in the 2D film dosimetry system of the Department of Radiotherapy of Coimbra University Hospital Center with a precision better than 2%. In the future, we plan to irradiate small animals, cell cultures, or other materials or samples.


Background and Objective: Previous studies have shown the adverse effects of gestationa l diabetes on hippocampal neuron density in animal model. This study was conducted to determine the effect of gestational diabetes on number of motor neuron in the ventral horns of spinal cord in 4, 8 and 12 weeks rat offspring. Materials and Methods: In this experimental study, 30 Wistar dams were randomly allocated in control and diabetic groups. Dams in diabetic group were received 40 mg/kg/ bw of streptozotocin (STZ) at the first day of gestational day (GD) and control group were received an equivalent v olume normal saline, intraperitoneally. Six offspring of cases and controls were randomly selected at the 4, 8, 12 postnatal weeks. Postnatal rats were scarified and sections (6 micrometer ) were taken from the cervical part of spinal cord, stained by cresyl violet. A photograph of sections was produced using an Olympus BX51 microscope and a DP12 digital camera. The number of motor neurons in the right ventral horns of spinal cord was evaluated in 100000 μ m 2 area of spinal cord using OLYSIA Autobioreport software. Results: The number of motor neurons in 4 weeks rat offspring were reduced (24.90%) in gestational diabetics compared to controls (17.16 ± 0.5 vs22.85 ± 2.1, P<0.0 5). The motor neurons in 8 weeks rat offspring were reduced (32.95%) in gestational diabet ics in comparison with controls (17.70 ± 1.7 vs26.40 ± 2.0, P<0.0 5). Also, the number of motor neurons in 12 week s rat offspring were reduced (24.38%) in gestational diabetics in comparison with controls (17.83 ± 0.7 vs23.58 ± 1.4, P<0.05). Conclusion: The uncontrolled gestational diabetes reduces the number of motor neurons in the ventral horn of spinal cord in rat offspring.


Background: With regard to health-threatening infections, Staphylococcus aureus is the leading cause of polymorphic infections varying from a banal tegumentary infection to numerous lethal illnesses. Furthermore, it is the third commonest bacterial cause of food-borne infections worldwide.This study aimed to investigate contamination, prevalence, and antibiotic resistance of S. aureus isolated from several widely marketed food products (raw and processed) in the region of Oran, Algeria.
Methods: A total of 350 food samples including prepared meals (n=110), dairy products (n=42), pastry (n=78), meat and its derivatives (n=97), and other commercially available foods (egg products, sweets, and sauces) (n=23) have been randomly purchased from diverse sale outlets and screened for S. aureus strains during the period from July 2021 to September 2022. The isolation and identication of S. aureus bacteria were preformed using conventional culture and biochemical tests such as catalase, coagulase, and DNase tests. Furthermore, the strains were screened for their resistance to five different antimicrobial drugs using the agar diffusion method.
Results: The overall prevalence of S. aureus determined among the collecteded samples was 31.14% (109/350), where, pastry products harbored the highest contamination rate (43.59%), and prepared meals, the lowest contamination rate (18.18%). The strains presented a high level of resistance (58.71-39.44%) for gentamycin and oxacilin, respectively. Moreover, the lowest level of resistance was observed against erythromycin 16.51%, and about 83% of strains presented multidrug resistance.
Conclusion: The significative prevalence and the high level of multidrug resistant of S. aureus highlights the seriousness to improve food contamination prevention programs and underlines that good hygiene practices at sale outlets has a major impact on the sanitary quality of commercialized food products.

Author(s): Gilliland, AJ; McKemmish, S | Editor(s): Cox, RJ; Langmead, A; Mattern, E | Abstract: In this paper we reflect on our engagement in research in Australia and the states emerging out of the former Yugoslavia relating to the role of recordkeeping and archiving in human rights and social justice contexts, and in post-conflict societies. This research has engendered a rethinking of participatory archiving as it relates to official as well as other types of records, an expanded conceptualisation of archival activism and a new concept of archival autonomy, recently defined by Evans et al. It also provides insights into the vital transformative roles that these factors individually and collectively might play in such situations. Based on our research findings, a review of relevant critical literature in archival studies, and our own immersive experiences over many years as archival and recordkeeping researchers, and as educators and practitioners, we present an integrated set of rights in records that acknowledge and respect the interests of the different agents who are involved or implicated in records and recordkeeping processes. The guiding principles for the development of the set of rights originate in deep reflection on what constitutes ethical and pluralized recordkeeping and archiving. While we may advocate for and invoke codified rights in support of transformative practice, the driving impulse to animate and prioritize 21st century recordkeeping and archival practice in human rights, social justice and post-conflict contexts has emanated from, and, we would argue, should ideally always emanate from personal, professional, institutional and national recognition of and response to ethical exigencies rather than as a result of externally-imposed rights-based directives.


Both English and Persian languages represent modality through auxiliary verbs, besides other means. The grammar systems of both languages include epistemic and root modality with some sort of similarities; however, they do not possess a one-to-one correspondence of modal auxiliaries, as a mean of conveying modality. Thus, translational shift is applied in many cases during the process of translating. This study is an analysis of such shifts in a parallel text, which consists of Jane Eyre, a novel by Charlotte Bronte (1955), and its Persian translation by Bahrami-harran (1998). The English and Persian modal auxiliaries are described and classified based on Palmer's (2001) model. The aim of this study is to detect different types of shifts based on Catford's classification in the translated text. To do so, one hundred and fifty sentences with modal auxiliaries were randomly selected from the source text and compared with the equivalents provided by the translator. Then, different types of shifts, based on Catford's, were identified and classified. The findings, descriptively suggesting how to translate modal auxiliaries from English into Persian, may have implications for linguists, translation researchers, and especially students of translation


As a virtual performer, technology has forced us to consider musical and aesthetic issues that go to the heart of what we believe performance to be. The most important of these issues may be considered through contrasting the ontological basis of human artistic performance with the detached form of musical presentation that the virtual performer offers. When the two types of presentation are combined, the virtual performance becomes an extension of the human presence. It can be illustrated that this extension of presence is something that many composers have explicitly developed in works for this medium.

The problem of nomenclature of wing venation in the Hymenoptera is discussed, and the main systems of terminology and their variations are reviewed.


This chapter, organized in three sections, reviews and critiques the history of archaeological practice and interpretation pertaining to early Christian monastic sites. The first section introduces readers to the development of cultural-historical, processual, and post-processual approaches in modern archaeology. The second and third sections address methodological problems related to the identification and dating of monastic remains. Selected case studies from the first millennium ce are cited to illustrate how modern historians and archaeologists have often over-interpreted the evidence available to them. This chapter aims to sponsor scholarly awareness about the limits of our current state of knowledge and to establish a set of more reliable and consistent criteria for evaluating what constitutes material evidence for the study of early Christian monasticism.


Crack closure in the near-crack-tip region has been considered to be an important contribution to the development of a crack-growth threshold for macroscopic cracks. Recent analytical work, however, has suggested that closure well back of the tip may be the controlling factor. In order to check on this possibility, material has been machined away far behind the crack tip in order to eliminate long-range closure. Removal of this material did not eliminate the threshold, but did lower the threshold level by approximately 10 percent for tests conducted on 6.3 mm-thick X7090-T6 powder metallurgy aluminum alloy.

 Despite unprecedented advances in global access to the Internet via smartphones, barriers remain to engaging hard-to-reach populations in many methods of health research. One potential avenue for conducting qualitative research is via participatory web-based media, including the free, popular social platform WhatsApp. However, despite clear advantages to engaging with participants over a well-established web-based platform, logistical challenges remain. This article reports evidence of feasibility and acceptability of WhatsApp as a method to conduct focus groups with Spanish-speaking women near the U.S.-Mexico border. The content focus was knowledge and perceived risks for exposure to Zika virus during pregnancy. Evidence is presented that WhatsApp is a secure, low cost, logistically feasible methodology that resulted in rich qualitative data from a population that is often reticent to engage in traditional research. The findings are noteworthy in a time when gold standard face-to-face focus groups are risky or precluded within safe COVID-19 guidelines. Other implications include more application and evaluation of WhatsApp for delivering one-on-one or group health education interventions on sensitive topics. This paper outlines key steps and considerations for methods replication or adaptation.


A wideband radiating element for mobile handsets was proposed for the benchmark activity of Antenna Center of Excellence. This action will consist of a comparison between numerical techniques and experiments. The different involved institutions have simulated this structure with their own codes and/or commercial codes (LEAT, IDS, IETR, UOB, UPV).


This article is the third in my series of articles exploring the application of complex adaptive systems (CAS) theory to legal systems. Building on the model outlined in the first two installments (in the Duke and Vanderbilt law reviews), this work examines the "arrow" or direction of the legal system in the context of the administrative state. Drawing from diverse work such as Burke's study of history's nonlinearity and Tainter's classic study of the collapse of complex civilizations, we argue that the administrative state is becoming too resource intensive and burdened by a proliferation of rules.


The invention provides a method for synthesizing and purifying irinotecan. The method prepares irinotecan that is an antineoplastic compound with high purity quotient through the purification of 7-ethide-10-hydroxycamptothecine that is an intermediate for synthesizing irinotecan and crystallization for impurity removal of hydrochloric piperidyl piperidine formyl chloride; secondary reaction is reduced, and the purity quotient as well as the yield of products are increased through improving the reaction condition at the same time, especially through cryoconcentration evolution; the purity quotient of the obtained products is more than 99.5 percent, and the single hetero is less than 0.1 percent. In addition, the method overcomes the disadvantages that the cycle is long, the solvent quantity is large, etc. caused by column chromatography that is used for purifying the products, and large scale production is easy to realize.


Dryaderces inframaculata Boulenger, 1882, is a rare species known only from a few specimens and localities in the southeastern Amazonia rainforest. It was originally described in the genus Hyla, after ~ 130 years transferred to Osteocephalus, and more recently to Dryaderces. These taxonomic changes were based solely on the similarity of morphological characters. Herein, we investigate the phylogenetic relationships and generic placement of D. inframaculata using molecular data from a collected specimen from the middle Tapajos River region, state of Para, Brazil. Two mitochondrial DNA fragments (16S and COI) were assessed among representative species in the subfamily Lophiohylinae (Anura: Hylidae) to reconstruct phylogenetic trees under Bayesian and Maximum Likelihood criteria. Our results corroborate the monophyly of Dryaderces and the generic placement of D. inframaculata with high support. Dryaderces inframaculata is sister to an undescribed taxon, Dryaderces pearsoni Ca1 Jungfer et al., 2013, and both are sister to Dryaderces pearsoni Gaige, 1929. These findings are relevant for further research on the systematics and biogeography of the genus.


The emerging Internet of Things (IoT) has several salient characteristics that differentiate it from existing wireless networking architectures. These include the deployment of very large numbers of (possibly) low-complexity terminals; the need for low-latency, short-packet communications (e.g., to support automation); light or no infrastructure; and primary applications of data gathering, inference and control. These characteristics have motivated the development of new fundamentals that can provide insights into the limits of communication in this regime. This paper discusses two issues in this context, namely security and low-latency, through the respective lenses of physical layer security and finite-blocklength information theory.
