It is becoming increasingly clear that communication between cells is carried out not only by the signaling molecules themselves, but also by many contextual and positional cues that arise from the way the signal is distributed and presented to the receptor. Many cells express transmembrane growth factors that use their extracellular domain for signaling to cells connected by adhesion. Some of these growth factors can also be receptors for a reverse signal from the adhesion partner. Secreted growth factors or their receptors can engage in contact-dependent signaling by associating with extracellular matrix (ECM) components and integrins. Signaling molecules can also reach cells at a distance via cytonemes that contact and activate the target cell through synapse-like structures.


The curriculum is a document that includes an overall program of education including experiences whichever individual learners have in school. The purpose of the curriculum is to provide a roadmap with clear goals and specific objectives. These things are planned according to a framework or research which present a professional practice (Kelly, 2009). Mathematics is an important subject at all levels of education. It is being taught from class one up to university level. In Pakistan, the curriculum of mathematics is designed at the national level (Government of Pakistan, 2006). Moreover, more importance has been given to elementary and secondary mathematics because these are the foundations for the future success of students. It is considered the mother of all sciences because mathematics is involved in every field. Generally, Mathematics is not liked by Pakistani students due to its rough, dry and hard nature (Aijaz, 2001). Students feel much difficulty in learning mathematics. The students in Public sector schools in Pakistan are unable to solve two-digit addition and subtraction. Only 48% of students can solve the basic arithmetic problem (Dubash, 2018; Pakistan, 2015). The curriculum of mathematics subject comprises of conceptual understanding which not only requires analytical but also involves logical thinking. The student's efforts play a vital role in the learning of mathematics (Ellis, 2011). However, the teachers of public and private schools failed to impart analytical skills among students due to lack of knowledge about curriculum (Gulzar, & Mahmood, 2019). The documents of the National Curriculum of Mathematics 2006 is standard-based which means it is based on the social efficacy ideology. Social efficacy ideology focuses on the skills and specific abilities of an individual. This ideology advocate for performance-based education because it believes that human life is based on the principle of performing specific abilities. Thus, Education should prepare students for specific abilities and skills (Harb & Thomure, 2020; Schiro, 1978). In the modern era, the curriculum based on the social construction ideology will improve the students learning outcomes because whenever students are allowed to construct their meaning of the world around them their understanding improves. Social construction ideology believes that knowledge, skills and intelligence can be utilized to solve the problems for the betterment of society (Kumar, 2019). Therefore, the study aimed to analyze the National Curriculum of Mathematics (NCM) which has been implemented from 2006-2007 educational year at the secondary level to find the gaps ABSTRACT


IoT devices have been widely deployed in many applications to facilitate smart technology, increased portability, and seamless connectivity. Despite being widely adopted, security in IoT devices is often considered an afterthought due to resource and cost constraints. Among multiple security threats, malware attacks are observed to be a pivotal threat to IoT devices. Considering the spread of IoT devices and the threats they experience over time, deploying a static malware detector trained offline seems ineffective. On the other hand, on-device learning is an expensive or infeasible option due to the limited available resources on IoT devices. To overcome these challenges, this work employs 'Federated Learning' (FL) which enables timely updates to the malware detection models for increased security while mitigating the high communication or data storage overhead of centralized cloud approaches. Federated learning allows training machine learning models with decentralized data while preserving its privacy by design. However, one of the challenges with the FL is that the on-device models are required to be homogeneous, which may not be true in the case of networked IoT systems. As a panacea, we introduce a methodology to unify the models in the cloud with minimal overheads and an impact on on-device malware detection. We evaluate the proposed technique against homogeneous models in networked IoT systems encompassing Raspberry Pi devices. The experimental results and system efficiency analysis indicate that end-to-end training time is just 1.12× higher than traditional FL, testing latency is 1.63× faster, and malware detection performance is improved by 7% to 13% for resource-constrained IoT devices.


Plasma-induced polymerization of 2-methacryloyloxyethyl trimethyl ammonium chloride (DMC) was studied in this paper. The effects of discharge time and discharge power on tubular-type reactor chamber temperature were accurately tested using a on-line thermocouple, and it was found that the influence of discharge time and discharge power on temperature in a tubular-type reactor chamber accorded with the following equation: T = 15.935942 + 0.279195t + 0.200020P − 0.000595t 2 + 0.004284t P + 0.005297P 2, where T is temperature (°C), t is discharge time (s) and P is discharge power (W). We also found that temperature was very important for the properties of poly(DMC). For T ≥ 130°C, poly(DMC) was cross-linked, and the highest rate of water absorbed by poly(DMC) was 15 g/g. For T < 130°C, poly(DMC) was linear, and the highest intrinsic viscosity of poly(DMC) was 420.2 cm3/g. The optimal polymerization conditions of linear poly(DMC) were: discharge time 60 s, discharge power 60 W.


Machine vision technology entered industrial application in the early 1970s, but due to high computing costs penetration has been limited. The machine vision business is pretty fragmented and the small technology companies are seeking repeat business in narrow business segments. Many new application areas with risks involved remain unsolved, because technology companies are not willing to carry the risks alone and the endusers are used to buying proven technology for their production lines. The European Commission-funded Information Society Technologies (IST) programme has been active in supporting machine vision technology transfer, take-up and research. This promotion has encouraged end-users and technology companies to work together in pilot applications and share the risks. Parallel European-wide dissemination efforts have carried these solutions to a wide audience of potential new users.


Bilateral medial medullary infarction is a rare type of stroke. Hypertrophic olivary degeneration (HOD) is usually secondary to the lesion involving the Guillain-Mollaret triangle with vacuolar degeneration of inferior olivary nucleus neurons and enlargement of inferior olivary nucleus. The primary lesions involving the Guillain-Mollaret triangle are usually located in midbrain, pons and cerebellum. A case of unilateral HOD secondary to bilateral medial medullary infarction is reported and the clinical characteristics, diagnosis and treatment are analyzed in order to improve the understanding of HOD.

Key words:
Medulla oblongata; Brain infarction; Nerve degeneration; Olivary nucleus


In the past decade,"Land finance"has provided financial support for the development of economy of china,which makes the city construction grown by leaps and bounds,as well as people's life improved greatly.Therefore,the positive effect of "Land finance" can not be denied,but the disadvantages of it is obvious..Therefore,the local finance income mode need to be transfer urgently.To establish new sustainable revence models,the government should change the mode of economic growth,develop entity economy,change "Land finance"to "Tax finance",improve the tax system,reform the existing local taxes,establish a scientific evaluation system of government performance and reform the land management system.


To the Editor, The prevalence of food allergy has been increasing worldwide in the last 10 years. Currently, 2%– 8% of the population in Western countries suffers from some type of food allergy. In Spain, seafood allergy has increased approximately 30% in the last decade, affecting both children and adults, with 10% affected by fish allergy.1 In this study, we have performed an initial screening of the allergens involved in the sensitization of 21 fish allergic patients from the South of Europe, considering: medical record and positive Skin Prick Test (SPT) to one of these five fish extracts (homemade, online repository): cod, hake, tuna, sole and sea bream (Table 1). Western blot was used to recognize the sensitization of these patients and LC/MS was used to characterize the allergen recognized by western blot. For practical reasons, clinical symptoms were recorded and classified into four categories: oral allergy syndrome (OAS), gastrointestinal symptoms (GI), urticariaangioedema (U/AE) and anaphylaxis (ANA). The study was approved by the Medical Ethical committee of ASISA Dr. Lobatón according to the Code of Ethics of the World Medical Association (Declaration of Helsinki). Written informed consent was obtained from each patient. Complementary study data can be found at https://zenodo.org/recor d/64766 37#.Yo68H S8lNQI. Angioedema was the most prevalent symptom, affecting 52% of fish allergy patients, followed by anaphylaxis symptoms (28%). The SPT positive results were: 62% sea bream, 38% sole, 47.61% hake, 38.09% tuna and 38.09% cod. Only 50% of the patients had a value >0.35 KU/L to sIgE cod using the ImmunoCAP System, and 75% of these patients were parvalbumin sIgE positive. Considering all patients, only 37% were sIgE positive to parvalbumin. Piruvate kinase (50 KDa), βenolase (48 KDa), glyceraldehyde dehydrogenase (36 KDa) and parvalbumin (11 KDa) were identified by LC/MS compared with a nonredundant protein database of Actinopterygii, using MaxQuant software. These proteins were previously identified as fish allergens2 (Figure 1A). Also, the fragmentation spectra obtained by the LC/MS analysis in gradient detection mode led three amino acid sequences of the tryptic peptides: VFDKEGNGTVMGAELR, VAYNQIADIMR and EGNGTVMGAELR with a sequence coverage of 13.9896 of myosin light chain of Pennahia argentata. Sensitization profile to a full extract of sea bream were study by SDSPAGE, IgEImmunoblotting and LC/MS. Parvalbumin: 11– 11.5 KDa (24%– 14% of patients respectively), myosin light chain 20 KDa (71%), glyceraldehyde dehydrogenase or tropomyosin: 32– 36 KDa (52%– 57% respectively), βenolase: 48 KDa (52%) and pyruvate kinase: 50 KDa (38%) (Figure 1A– C). 41 KDa band recognized by 95% of patients could not be considered because our pool of nonallergic people recognized this band, which was characterized as alphaactin. Briefly, we observed 16 profiles of sensitization, being myosin light chain, the most frequent allergen detected in our population (71%) and parvalbumin the less allergen recognized (38%). These results agree with the sIgE analysis, in which only 37% of patients had positive results to Gad c 1. Clinical symptoms seem to vary depending on sensitization IgE profile found it. In that way, patients monosensitized to myosin light chain suffered from symptoms of urticaria, angioedema or anaphylaxis. One patient sensitized to myosin light chain and parvalbumin suffered from symptoms of urticaria and angioedema and one patient was sensitized to both glyceraldehyde dehydrogenase bands associated with oral allergy symptoms. The combination of myosin light chain with other allergen produced different symptoms: urticaria, angioedema or gastrointestinal symptoms (complementary data). In this study, we have noted that the response to SPT of the different type of fish were different so that would be relationship with the homology of the different allergen depending on the species studied. So, we have studied the homology of myosin light chain in Sparus aurata, Cyprinus carpio, Thunnus thynnus and Gadus morhua using the neighbour joining method. Distance was considered when the value was higher than 0.16.3 We could observe that myosin light chain from Sparus aurata, Cyprinus Carpio y Thunnus thynnus were the nearest to Gadus morhua in the phylogenetic tree, although the difference was lower than 0.16. It should be noted that Solea senegalensis belonged to other group with respect to Sparus aurata (0.478567 units), showing a low similitude between them (25.58%). Also, we studied the similitude between Sparus aurata and Penaeus vannamei, showing a distance in the sequence of 0.783224 units, which agrees with the similitude in the sequence of peptide 34.23% (ROT75420.1) OR 21,48% (ROT78605.1). Six fish and crustaceous allergic patients were studied by SDSPAGE with an extract of Penaeus kerathurus did not recognized myosin light chain band.


Recent research in experimental law and economics shows that the imposition of a fine, intended to deter some harmful behavior, may crowd out moral motivation: the behavior occurs more frequently even though a payment is charged to discourage it. In A Fine is a Price, Gneezy and Rustichini (2000) suggest that the payment may induce subjects to frame the intended prohibition as a permission in exchange for a price. Obviously, the effect if confirmed may impact almost any form of public regulation or contract drafting. May fines charged for plastic bags in fact increase usage? May penalty clauses in contracts increase the likelihood of breach?

Our study tests this theory, distinguishing it from six alternative crowding-out mechanisms and from confounds in Gneezy and Rustichini's original day-care study.

In our experiment, subjects are offered a contract to perform a real effort task. Subjects are paid upon the acceptance of the contract. If they breach the contract, they keep their payment, but burden their partner with an additional workload. We vary our treatments by specifying different amounts that subject need to pay if they do not perform: T1 specifies no payment, T2 stipulates a low fine disproportional to the extra workload imposed, and T3 stipulates a proportional fine; the payments go to the contractual partner.

We find the same mean performance level across all three treatments. However, splitting the sample according to the subjects' social value orientation reveals a strong crowding-out effect in the pro-social group and an offsetting price effect for the pro-self players.

Our last treatment, T4, aims to identify the mechanism behind this crowding out effect. In this treatment, the payment is made to the experimenter, instead of the contractual partner as under T2 and T3. In the absence of a transfer between the parties, T4 forces subjects to view the fine as a penalty, instead of an exchange. Results show that T4 crowds in the pro-social subjects' compliance, providing causal evidence for the Fine-is-a-Price hypothesis.


A new scalable method for purification of single-wall carbon nanotubes (SWNTs) by using microwave heating in air is developed. The microwaves couple to the residual metal catalyst, raising significantly the local temperature leading to both the oxidation and rupturing of the carbon passivation layer over the metal catalyst particles. With this protective carbon coating weakened or removed, a mild acid treatment is then sufficient to remove most of the metal in the sample, leaving the nanotubes in tact. Using microwave processing and 4 M HCl acid reflux for 6 h we were able to remove residual metal (Ni, Y) in arc-discharge SWNTs to a level lower than 0.2 wt % (∼0.04 at. %). Results from transmission and scanning electron microscopy, Raman spectroscopy, and thermogravimetric studies were discussed.


This paper aims to find out the effect of dividend on the share price in India. For this purpose, researchers collected data from a sample of 50 firms of the NIFTY-50 index from the period of 2008-2018. Independent variables are dividend per share and retention ratio. Control variables are return on equity, profit after tax, and earnings per share. Panel regression methods like pooled OLS regression, fixed-effect model, and random effect model have been applied. The results supported the fixed-effect model. The findings confirm hypotheses that dividend per share and retention ratio have no significant impact on share price, which further affirms Miller and Modigliani's theory stating that share prices are unaffected by dividend payments by the firm. However, the result shows that earnings per share and return on equity have a significant impact on share price, attributing to the viewpoint that companies which are effective in utilizing capital invested by shareholders and make a profit for them are valued high.


Except for some trenches dug in 1865-6, when the Thirsk and Malton railway was constructed, no systematic excavation of the Roman station at Malton has ever been made until 1927. Although casual Roman finds have been plentiful, few of them have been published and little is definitely known about the site and its history, the current Ordnance Survey map merely marking the Fortress as 'Supposed Roman Camp'. Many of the statements made about it in the past have been purely conjectural. As a result of recent investigations, the writers believe that the time has come when some general statement can profitably be made as to the extent of the site, its importance in Roman times, and the nature of the occupation of the neighbourhood. Amongst those who have written of the antiquities of Malton in the past, one writer, Rev Dr Young (History of Whitby, 1817) shows unusual judgment and penetration in an age when antiquaries were only too ready to repeat the guesses of their predecessors. The exact position and extent of the Malton fort were unknown before 1927, and few finds are recorded before the 19th century, yet Dr Young recognized it as a place of importance and guessed its position correctly.

PurposeThis paper aims to explore the causal relationship of user-generated content (UGC) on trust in UGC (TUGC), destination image (DI) and tourist visit intention (VI) guided by the stimulus-organism-response (SOR) theory. This work further examined the mediating effect of TUGC and DI between UGC and VI.Design/methodology/approachData were collected through online and personal-administered surveys and randomized sampling. This work employed partial least squares structural equation modeling (PLS-SEM) to test the proposed model empirically.FindingsIn line with the SOR Theory, this work found UGCs that induce positive emotions and connection to the users motivate VI rather than UGCs that are predominantly factual. Furthermore, UGCs are considered reliable, authentic and less biased than brand-generated content. The findings of this work contribute to the theoretical understanding of UGC to VI in a destination.Practical implicationsThis work proposes that destination marketers prioritize UGC that evokes positive emotions and connections with users, as it is more effective in encouraging VI. Strategies such as incentivizing content creators, improving online presence and engaging influencers can maximize UGC. Enhancing online traffic quality, visibility and interaction and implementing content policies are crucial for UGC's effectiveness. Marketers should align destination products with tourists' interests and collaborate with influencers for affiliate marketing to increase tourist-generated UGC. Furthermore, improved connectivity encourages UGCs about the destination.Originality/valueIn tourism marketing, UGC has become a valuable information source for tourists in making informed travel decisions. UGC is a tourist-generated content that offers factual information and authentic experiences through images, videos or text posted through social media platforms. UGC is considered more reputable than travel firms and the mainstream media as an information source. Due to the limited works on UGC in the literature, the influence of UGC on tourists' VIs has remained unexplored at the time of writing. This work bridges this gap by empirically examining the impact of UGC on Gen Z tourists' VI guided by the SOR theory.


The rapid uptake of digital technologies promises great benefits for citizens to transact and communicate in a free and open space. Yet this freedom may also lead governments to impose regulation and to attempt to filter content that may be considered offensive or politicised in nature. We empirically study public perceptions of internet censorship, perceived personal consequences of internet filtering and efforts to circumvent censorship through a survey of 112 residents of Indonesia, analysing our results with PLS structural equation modelling. Our findings show that perceived need for filtering, as well as social norms strongly influence public attitudes. We also find that uncertainty avoidance – a cultural trait also influences these attitudes. However, the use of circumvention tools is determined by perceived personal consequences rather than attitude. Our findings address the lack of research in this space while addressing implications for government and policymakers.


Efficient Market is defined as the market where com m n stock prices fully reflect all available information related to these tocks. As a result of this ∗ Yrd.Doç.Dr., Çanakkale Onsekiz Mart Üniversitesi, Gelibolu Piri Reis Meslek Yüksek Okulu, firstname.lastname@example.com 2 / Ahmet Kamil TUNÇEL definition, no one has a chance to get abnormal ret urn by using this information. By this approach, no one has also a ch nce to record a good performance more than the average in the point of s electing a security. In an efficient market the actual price of a security wil l be a good estimate of its intrinsic value so, there is not any undervalued or overvalued security in the market. This paper targets to test weak form efficiency of Turkish stock market.

Stylometry is the study of determining the author of a document based on the linguistic features contained in the document. Previous work in this area has yielded impressive results, but assumes that the training and testing documents are similar key attributes, namely the domain and setting in which they are written. This paper focuses on the scenario where this assumption cannot be made. We determine that standard methods in stylometry do not perform well when the training and suspect documents differ in this way. For example, when working exclusively with blogs we obtain an average accuracy of 93.30% and with Twitter feeds we obtain an average accuracy of over 98.99%. However, when we apply the same method to try to identify a twitter feed via a blog's writing, accuracy falls drastically. We provide a method to improve this cross-domain accuracy to 88.89%. Being able to identify authors across domains facilitates linking identities across the Internet, making this a key privacy concern.


Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation. Cloud computing share distributed resources via network in the open environment thus it makes security problems. So we are in great need of encrypting the data. We proposed a method to build a trusted computing environment for Cloud Computing system by providing Secure cross platform in to Cloud Computing system though MAC. In this paper some important security services are including like authentication, encryption and decryption are provided in Cloud Computing system.


The diet of larval Pacific hake, Merlucciusproductus. consisted primarily of copepod eggs and calanoid copepod adults, copepodites, and nauplii, based on an examination of material collected in March 1975 off southern California and northern Baja Califomia. In spite of a large mouth, Pacific hake larvae ingested a broad size range of prey, with a concentration of food particles 70200 pm in width. First-feeding Pacific hake larvae fed upon a wide range of prey (50 to about 400 pm prey width), and the range in prey sizes changed little with larval length from 3.0-10.7 mm. Although copepod eggs, nauplii, and copepodites were a significant portion of the diet in numbers of prey, adult copepods contributed about 74% of prey volume. Observations of feeding incidence in relation to time of capture revealed a slow rate of gut evacuation. Larvae began feeding at about lo00 hours, and the number of prey items found in the gut increased during the day, reached a maximum after sunset, and thereafter decreased gradually. The comparatively large mouth, slow evacuation rate, and ability to feed on cope@ stages from eggto adult seem to form an adaptive strategy for success in the relatively deep and cold strata inhabited by Pacific hake larvae.

(c) Cautious actors run to a place of safety in the event of an accident. (e) Firefighters extinguish the fire while daring actors look on. Abstract There has been growing academic and industry interest in the be-havioral animation of autonomous actors in virtual worlds. However , it remains a considerable challenge to automatically generate complicated interactions between multiple actors in a customizable way with minimal user specification. In this paper, we propose a behavior authoring framework which provides the user with complete control over the domain of the system: the state space, action space and cost of executing actions. Actors are specialized using effect and cost modifiers – which modify existing action definitions, and constraints which prune action choices in a state-dependent manner. Behaviors are used to define goals and objective functions for an actor. Actors having common or conflicting goals are grouped together to form a composite domain , and a heuristic search technique is used to generate complicated multi-actor behaviors. Using our method, users can work at any level of abstraction – from specifying scripted sequences of actions , goals, constraints on trajectories of one or more agents, to specifying high-level motivations for an entire scene. We demonstrate the effectiveness of our framework by authoring and generating a city simulation involving multiple pedestrians and vehicles that interact with one another to produce complex multi-actor behaviors .

The crystal structure of the title compound, [Co(C 4 H 2 O 4 )(C 7 H 6 N 2 ) 3 ] n , consists of polymeric chains of the Co II complex. Two maleate dianions and three benzimidazole ligands coordinate to the Co II atom with a distorted octahedral geometry. The maleate dianions bridge neighbouring Co II atoms via both terminal carboxylic acid groups, one of which is monodentate and the other bidentate, to form a helical structure of alternating maleate dianions and Co II atoms, with a pitch height of 9.2667 (17) A. The absolute structure has been determined, and the crystal contains only right-handed helices. Intrahelical N-H...O hydrogen bonds stabilize the helical structure, while interhelical N-H...O hydrogen bonds link neighbouring helices to form the supramolecular structure.

We report on the development of a ytterbium-based disk amplifier for an ultra-short pulse laser using edge-pumped architecture and offering excellent scalability to high-average power in the kW-range. The disk has a composite construction with undoped perimetral edge designed to channel pump light while efficiently outcoupling amplified spontaneous emission. Uniform extraction of waste heat together with uniform pumping offers very low optical path distortion and allows for amplification of near diffraction limited beams in nanosecond-class pulses. This work discusses performance modeling of the edgepumped disk amplifier using a newly developed time-dependent 2-dimensional (spatial) model for dynamic pumping and extraction. Selection of laser materials and an innovative two-disk amplifier architecture for multiple extractions are also presented.


The main attributes that have been used to conserve the energy in wireless sensor networks (WSNs) are clustering, synchronization and low-duty-cycle operation. Clustering is an energy efficient mechanism that divides sensor nodes into many clusters. Clustering is a standard approach for achieving energy efficient and hence extending the network lifetime. Synchronize the schedules of these clusters is one of the primary challenges in WSNs. Several factors cause the synchronization errors. Among them, clock drift that is accommodated at each hop over the time. Synchronization by means of scheduling allows the nodes to cooperate and transmit data in a scheduled manner under the duty cycle mechanism. Duty cycle is the approach to efficiently utilize the limited energy supplies for the sensors. This concept is used to reduce idle listening. Duty cycle, nodes clustering and schedules synchronization are the main attributes we have considered for designing a new medium access control (MAC) protocol. The proposed OLS-MAC protocol designed with the target of making the schedules of the clusters to be overlapped with introducing a small shift time between the adjacent clusters schedules to compensate the clock drift. The OLS-MAC algorithm is simulated in NS-2 and compared to some S-MAC derived protocols. We verified that our proposed algorithm outperform these protocols in number of performance matrix.


Tantalum‐doped indium tin oxide thin films were deposited by a cosputtering technique with an ITO target and a Ta2O5 target. The variations of microstructure, electrical and optical properties with substrate temperature and annealing temperature were investigated in some detail. Ta‐doped ITO thin films showed better crystalline structure with different prominent plane orientation by different heating process. ITO:Ta thin films deposited at room temperature showed better optical and electrical properties. Increasing substrate temperature and reasonable annealing temperature could remarkably improve the optical and electrical properties of the films. The variation of carrier concentration had an important influence on near‐IR reflection, near‐UV absorption and optical bandgap. ITO:Ta thin films showed wider optical bandgap. ITO:Ta thin films under the optimum parameters had a sheet resistance of 10–20 Ω/sq and a transmittance of 85% with an optical bandgap of above 4.0 eV. (© 2008 WILEY‐VCH Verlag GmbH & Co.

This paper presents a variation of the methodology, established in a previous paper, to test a modular system for nonconflict using abstractions of its supervisors. In this work, information about the model and control structure of the system are used to derive a solution where some of the conditions established before are not required. The local modular approach is used to design the supervisors and supervisor reduction techniques are also used to help defining the set of events that are kept in the abstractions.


Everything indicates that the problem of outlining the state of strategic communication is not to realize the state of the question regarding where we are, but to realize the question whose status is attempting to clarify the actual phenomenon being discussed. Building on this concern, the author embarks on a journey through four related knowledge areas, including studies of strategy and communication or, more specifically, about "strategic communication", as well as those studies on strategy and communication made from life sciences. The author concludes that there are two features that characterize the present time: (1) the strong movements of the communication and the strategy toward the new scientific paradigms, and (2) the trend to the incarnation of both phenomena in human beings (relational) and in collective subjects (organizational). The author suggests a new jump into the study of strategic communication as a biological phenomenon and not just from a social, political or economic basis. The driven idea is that, by integrating strategic communication into real life, it will facilitate the long-awaited unification of this field of study.

Commensal bacteria constantly reside in our mucosal sites, especially in the intestine and create a mutually beneficial condition of symbiosis with the host. The physical and molecular crosstalk between host and gut microbiota is established at the surface of intestinal epithelial layer. It has been reported that specific epithelial carbohydrate chains, fucoses, are involved in the attachment of bacteria and viruses and ablation of these fucoses seems to be associated with the onset of Crohn's disease. In spite of this important role, the mechanism of the induction and regulation of epithelial fucoses is not fully understood. Here, we show that specific commensal bacteria, segmented filamentous bacteria (SFB), physiologically induce fucoses on the ileal epithelial cells. To analyze the role of commensal bacteria in the induction of fucosylated epithelial cells (F-ECs), we firstly checked germfree mice. F-ECs were not found in germfree mice, while a large number of F-ECs were observed in the ileum of SPF mice. When we analyzed the ileal bacterial population to identify bacteria responsible for the induction of F-ECs, SFB were dominant in the ileum. Mono-colonization of SFB led to the development of F-ECs in germfree mice. Furthermore, F-ECs were abolished in SFB deficient mice bred in Jackson laboratory, indicating that SFB physiologically induce F-ECs. Our findings provide the basis of mutually beneficial system between the host and commensal bacteria.


Disease resilience is a concept that combines resistance and tolerance. Depending on individual resilience, the performance of pigs can be different in commercial herds, where they are exposed to various pathogens, compared to nucleus breeding herds. Here, we designed a natural disease challenge model in pigs to measure resilience traits and to generate population-level gene expression data. Our results suggested that gene expression patterns in young healthy pigs showed significant associations with mortality following exposure to disease and are, therefore, promising as early disease resilience predictors for use in nucleus breeding programs.


The article is devoted to the study of limitations and resources of interaction between government and business in modern Russian conditions, the definition of the most popular and promising forms of cooperation in modern Russian conditions. Unlike the developed democracies, the model of interaction between government and business, built on the balance of interests and partnership, has not yet developed in our country. Based on the expert survey of municipal employees conducted by the All-Russian Council of Local Self-Government (with the participation of the authors) the main risks (the need for additional funding from the municipality, reputational losses in the event of project failure or failure to achieve its objectives, delays the implementation of projects by the contractor) and barriers to the implementation of practices in municipalprivate partnership (lack of opportunities to provide motivation for private investment, business disinterest). It is concluded that the existing malfunction of the institutional field does not allow creating a basis for normative-fixed practices of partnership between government and business, and municipal-private partnership becomes utopian for municipalities. The most promising form of interaction between government and business is the economy of cooperation as an effective tool for socio-economic development of the territory. At the same time, the active and flexible position of local authorities, the analysis of interests and needs of the business community, and the effective use of municipal property should be the conditions for implementing a new form of interaction between the public and private sectors. The principles of economic cooperation can be adapted and used in the context of the socio-economic development of Russian territories.


A bromine-containing copper organic coordination compound was prepared by the reaction of tetrrpropylammonium bromide with copper bromide in ethyl acetate solution. The compound obtained was characterized with FTIR, XRD, ICP-AES and EA. Meanwhile, its catalytic performance for the oxidative carbonylation of methanol was investigated. The results showed that the introduction of ligand could change the density of copper electron cloud, which improved the redox property for the oxidative carbonylation of methanol to prepare dimethyl carbonate. In the presence of strong base and weak acid salts, the per pass conversion of methanol could reach 57% under the reaction conditions of temperature 383 K, pressure 3.5 MPa, and the mass concentration of catalyst in methanol 0.20g•ml^(-1).

Dear Editor-in-Chief
There is warning about ignoring the environment, in particular solid waste and the problem recently has been taken into consideration by the world (1). Since the generation process has a principal role in waste management, the generators place should not be ignored (2). Fast population growth, industrial development, technological advance, and human desire to increase material consumption and following more waste production have led to a massive social and economic crisis in human societies (3). Given waste management importance and considering that Arak, central Iran has become one of the industrial hubs in the country due to the primary industrials and that is the15th most populous city of the country (4). Hence, the present study is to assess the citizen's attitude toward the waste management to develop the appropriate educational methods


We study the impact of Sommerfeld enhancements on the neutralino relic abundance calculation for heavy neutralino dark matter including co-annihilations of further nearly mass-degenerate neutralino and chargino states. An effective field theory is developed that systematically resums the enhanced radiative corrections to annihilation rates of slowly moving neutralinos and charginos. The framework is applied to heavy wino- and higgsino-like scenarios and models interpolating between these cases.


Cardiovascular disease (CVD) is the leading cause of death in patients with nonalcoholic fatty liver disease (NAFLD). The current analysis expands the knowledge on atherogenic lipid profiles in NAFLD by modeling changes in low‐density lipoprotein cholesterol (LDL‐C) and total cholesterol (TC) in a prospectively enrolling real‐life study cohort to inform physicians on the cardiovascular (CV) event risk based on these changes. A total of 304 patients with histologically confirmed NAFLD were included (mean age, 52 years; equal sex distribution). Of these, 129 (42.4%) patients exhibited a NAFLD activity score ≥4 and 186 (61.2%) had at least intermediate fibrosis ≥F2. The median TC levels were 209 mg/dL (interquartile range [IQR], 183, 239), LDL‐C 131 mg/dL (IQR, 103, 152), and high‐density lipoprotein cholesterol (HDL‐C) 45 mg/dL (IQR, 38, 52). Only 16.9% of patients received lipid‐lowering therapy. According to the LDL/HDL ratio, 69 (23.7%) patients exhibited a high CV risk. The 10‐year CV event risk according to the Framingham risk score (FRS) was low in 91 (41.2%), intermediate in 59 (26.7%), and high in 71 (32.1%) patients and higher in the ≥F2 NAFLD population. A moderate increase in LDL‐C levels by 20 mg/dL led to a transition of 20% of patients into the high‐risk group when assessing the LDL/HDL ratio. According to the FRS, 6 (2.7%) patients moved from low to intermediate and 11 (4.9%) from intermediate to high CV risk. Conclusion: Patients with NAFLD exhibit a substantial CV event risk and are frequently undertreated with lipid‐lowering medication. Moderate increases in LDL‐C would result in worsening of the CV event risk in approximately 7.8% of all patients without a history of CVD.

Recently, local correlation tracking has been applied to magnetograms to estimate photospheric velocities. This Letter demonstrates that local correlation tracking is inconsistent with the magnetic induction equation, which governs the temporal evolution of the photospheric magnetograms. A modified formulation, consistent with the magnetic induction equation, is presented for accurately following photospheric magnetic footpoints.


As one of the important bone regeneration materials, α-calcium sulfate hemihydrate (α-CSH) has attracted widespread attention. In this study, a facile method was developed to prepare α-CSH with low aspect ratio via high-gravity continuously reactive precipitation of a calcium sulfate dihydrate (CSD) precursor, using ethanol as a morphology modifier in a rotating packed bed (RPB) reactor, combined with CaCl2 salt solution method under atmospheric pressure with the addition of citric acid with a low concentration (0.06 wt %). The precipitation time of CSD powders in the RPB was dramatically shortened from 30 min to 1 s, and the precursor exhibited more regular short rod shapes and much smaller size, compared to that obtained in a conventional stirring tank reactor (STR). Furthermore, calcium sulfate bone materials with high stability and good mechanical property were prepared by mixing α-CSH and normal saline with a liquid–solid ratio of 0.6. The RPB products had a higher compressive strength (2–3 times) th...


Oxidation of cyclotriveratrylene (CTV) with chromic acid gives cyclotriveratrylen-5-one (3) accompanied by some cyclotriveratrylen-5,10,15-trione (9), which is formed in higher yield by similar oxidation of the monoketone. The ketone (3) is converted into the corresponding secondary alcohol (4) by hydride reduction and into the tertiary carbinol (6) by methyl-lithium. The latter alcohol easily loses water to form the 5-methylene derivative (7); the isopropyl analogue cannot be isolated, since it spontaneously dehydrates to the 5-isopropylidene derivative (8).The relative stabilities of the various possible conformations of the ring system, and their rates of interconversion when more than one is observable, depend on repulsion between non-bonded atoms, ring-strain, and (when C-5 is trigonal) conjugation. The conformations have been established by 1H n.m.r., i.r., and u.v. spectra. CTV itself exists only in the 'crown' conformation (A); the 1H n.m.r. spectrum remains unchanged up to 200°. The 'crown' conformation with pseudo-equatorial OH is also the most stable one for the secondary alcohol (4): both the labile secondary alcohol (5), isolated by reduction of the ketone (3), and the methyl carbinol (6) exist in the 'flexible' form (C).In the compounds with C-5 trigonal, conjugation, which is not possible in the 'crown' conformation, also plays a part, so that the ketone (3) adopts only the 'flexible' conformation (B) with C2 symmetry and an enlarged C–CO–C angle. In the less highly conjugated methylene derivative the 'crown' conformation (A) also occurs, although the 'flexible' one (B) still predominates (K= 3·2). The two conformers equilibrate slowly at room temperature. The isopropylidene derivative (8), however, exists predominantly in the 'crown' conformation.In the presence of dilute acid both the 'crown' and 'flexible' alcohols react with ethanol to give the ethyl ethers; the rate for the latter is at least 6 × 104 times faster. That the 'crown'⇌'flexible' conformational equilibrium for the intermediate carbonium ion is faster than its chemical reaction and lies, like that of the ketone (3), on the side of the flexible form is indicated by the fact that the flexible ether (12) is the primary product of etherification of both the alcohols (4 and 5).


This paper studies the basic framework of economic factors mobility framework during the process of integration of urban and rural from the perspective of system dynamics. By positive feedback of economic factors mobility, the causal loop diagrams of human resources, technology and funds are analyzed. Furthermore, a flow chart and system dynamics model are established. Vensim PLE is used to simulate and test the validation and application value of model. The simulation results show that the model could fit the revolution of practical integration effect, and provide valid suggestions for regional economical management.


The balance in interests supported by our current intellectual property laws has made conventional libraries highly successful and valued social institutions. That balance is currently being disturbed by the accelerating shift to electronic publication and dissemination. This comment piece argues that both the public goods aspects and authorship protection aspects of current public library arrangements need to be supported in future geolibrary digital environments.

Radiopharmaceutical practices are divided into large-scale industrial manufacturing and small-scale "in-house" hospital radiopharmacy unit. The recent evolution of nuclear medicine involves deep consequences in this ever-present regulatory state, and hospital radiopharmacy units cannot be considered as contract manufacturing organizations (CMO). This review provides an updated status report of the official (and non-official) guidelines supporting the regulations required to meet hospital and industry common radiopharmaceutical manufacturing standards to facilitate the current and future innovative radiopharmaceutical development.


This study prospectively assessed the prevalence of oral candidal carriage and oral candidiasis in known HIV-seropositive individuals (n = 121) and other dental attenders in Edinburgh (n = 614). Candida species were isolated from 57.4% of dental attenders and 93.4% of HIV-seropositive subjects. Clinical evidence of oral candidiasis was observed in 6% and 52% of these groups respectively, erythematous forms of candidiasis being the commonest in both groups.

In this paper, we experimentally studied an air breathing high temperature PEM fuel cell at steady operating conditions to investigate the effects of CO poisoning at different temperatures ranges between 120°C∼180°C. The effects of changes in temperatures with different amount of CO poisoning on the current-voltage characteristics of the fuel cell are investigated. Experimental data of this type would be very useful to develop design parameters of fuel processor based on reformate hydrocarbons. The high CO tolerance of high temperature PEM fuel cells makes it possible to use the reformate gas directly from the reformer without further CO removal. Here we considered the fact that a steam reformer is a consumer of heat and water, and fuel cell stacks are a producer of heat and water. Thus, integration of the fuel cell stack and the reformer is expected to improve the system performance. The results obtained from the experiments showed variations in current-voltage characteristics at different temperatures with different CO poisoning rates. The results will help to understand the overall system performance development strategy of high temperature PEM fuel cell in terms of current-voltage characteristics, when fed with on-site reformate hydrogen gas with variable CO concentrations.Copyright © 2008 by ASME


There is provided a method for contacting an outer contact surface (3) with a test contact (1). The outer contact surface (3) has a galvanically applied coating (4) made of a metal or a metal alloy. Before making the contact between the outer contact surface (3) and the test contact (1), the outer contact surface (3) with a liquid (5) is wetted. The liquid (5) comprises an inhibitor which contains an aliphatic hydrocarbon, coupling agents that contain white mineral oil and ethyl acetate, and lubricants. The liquid (5) causes the contact resistance between the outer contact surface (3) and the test contact (1) is low.


Strategic differences have an important impact on the quality of surpluses. Based on the perspective of surplus persistence, this paper uses a total of 8917 data of A-share listed companies in Shanghai and Shenzhen in China from 2014-2019 as the research sample, and uses a first-order linear autoregressive model to explore the relationship between strategic differences and surplus persistence of listed companies, and the moderating role of property rights nature in this relationship. The study finds that the greater the strategic differences, the lower the surplus persistence; the negative relationship between strategic differences and surplus persistence is more significant in non-state-owned enterprises compared to state-owned enterprises. Further breakdown of the surplus items reveals that strategic differences affect the overall surplus persistence mainly by influencing the persistence of the accrual part of the surplus.


In this paper, we show that the decision support system (DSS) utilizing the traditional technical analysis is further improved by the AI techniques and the soft computing techniques such as GAs and NNs.

Aging generally has a negative impact on temporal processing. Four experiments using vowel sequences are presented from a large series of temporal processing studies of age‐related changes across three sensory modalities. These four experiments used adaptive tracking to determine the smallest temporal difference between the onsets of vowels (SOA) that preserved identification of either the vowel sequences or ear presented. Vowels in the four words (pit, pet, pot, put) from a male speaker were processed using STRAIGHT to have the same length (70 ms) and F0 (100 Hz) and equated for rms level. Young (N=40) and elderly (N=40; 60–79 years) adults identified the vowels in isolation with better than 90% accuracy. Preliminary analyses based on 40% of the data are summarized here. Baseline performance by young listeners in the monaural, two‐vowel sequence task was SOA=20 ms. For the other three conditions (monaural four‐vowel sequences, dichotic two‐vowel sequences, and dichotic two‐vowel sequences for ear present...


INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a disease characterized by progressive poorly reversible airway destruction. Cardiovascular disease accounts for significant morbidity and mortality in chronic obstructive pulmonary disease (COPD). Its prevalence and mechanisms of association have not been elucidated. The study aimed to assess the prevalence of echocardiographic abnormalities and potential risk factors in patients with COPD. MATERIALS AND METHODS: A total of 86 COPD patients were enrolled in the present study. All patients were subjected to full medical history and clinical examination, chest radiography, complete blood count, lipid profile, spirometry, 2D-echocardiography. RESULTS: 86 patients included in our study. Out of 86 patients, 74( 86%) were male and 12 ( 14 %) were females. Male to female ratio was 6.1:1. Mean age was 58.2 ± 12.7 years. Severity of COPD patients classify according to GOLD criteria. Out of 86 patients, 15 patients had FEV1 30 mmHg which was seen in 40 cases (46.5%) . Out of 50 patients, 15 (17.4%) patients had mild, 5 (10.5%) had moderate and 18 (18.6%) had severe pulmonary hypertension, 12 (13.6%) patients had right ventricular systolic dysfunction, 11 (12.8%) had left ventricular systolic dysfunction and left ventricular hypertrophy. 16 ( 18.6%) had cor pulmonale. CONCLUSION: Echocardiography is helpful in early detection of cardiac complication in COPD patients.


There are some issues in Frederic G. Reamer's article ("Conflicts of Professional Duty in Social Work," December 1982) which are indicative of certain misinterpretations which demand clarification. The problems detected in this article are also evident in Reamer's book and recent reviews have already been prepared concerning them. 1 I will limit my comments to the one problem which emanates from this article. The author identified conflicts which occur for the social worker as he or she endeavors to choose the "right" action from the "conflicting" dictums listed in the NASW Code of Ethics. Reamer then enunciated (what he perceives to be) the ideas of W. D. Ross. Reamer interpreted Ross to say that it is, indeed, a complicated matter' 'to resolve differences of opinion about which of two or more conflicting prima facie duties should take precedence and be regarded as one's actual duty." Knowing that Ross was an intuitionist, Reamer argued that intuitive mechanisms are insufficient for settling ethical conflicts, thereby posing an "Alternative to Intuition." Unfortunately, Reamer failed to capture the essence and foundation of Ross's ethical system, which in fact is similar to the ethical system developed for the social work profession by Dr. Charles S. Levy. 2 Ross's work was inspired by H.A. Prichard, who in 1912 published an article entitled, "Does Moral Philosophy Rest on a Mistake?" The mistake moral philosophers almost invariably have made, Prichard contended, is their attempt to provide reasons capable of establishing that some act we believe to be correct is really correct. Prichard said that ethical obligation arises from the intrinsic obligation that one has in a certain situation. Hence, the social worker owes something to another individual because he or she is a


This dissertation shows how the automatic text-mining of the biomedical literature can assist human experts in their work. We look at three real cases, wherein automatic annotations effectively leveraged the feedback of experts. We worked with the renowned scientific repositories PubMed, UniProtKB, and FlyBase; we showed that the newly developed methods saved time and costs in database curation. We applied techniques of active learning, named-entity recognition, and relationship extraction.


Automatic Differentiation (AD) is a powerful tool that allows calculating derivatives of implemented algorithms with respect to all of their parameters up to machine precision, without the need to explicitly add any additional functions. Thus, AD has great potential in quantum chemistry, where gradients are omnipresent but also difficult to obtain, and researchers typically spend a considerable amount of time finding suitable analytical forms when implementing derivatives. Here, we demonstrate that automatic differentiation can be used to compute gradients with respect to any parameter throughout a complete quantum chemistry method. We implement DiffiQult, a fully autodifferentiable Hartree-Fock (HF) algorithm, which serves as a proof-of-concept that illustrates the capabilities of AD for quantum chemistry. We leverage the obtained gradients to optimize the parameters of one-particle basis sets in the context of the floating Gaussian framework.


Purpose To investigate the histopathological features of cystic lung diseases( CLD),and to discuss the timing of clinical interventions. Methods HE and immunohistochemical staining were performed and reviewed in 125 cases of CLD. Results 125 cases of CLD aged from birth to 11 years and 6 month,with an average age of 23. 0 months,median age 15 months,of which 60 cases were less than 1 year( 48. 0%). 75 cases were male and 50 cases female,with male to female ratio of 1. 5 ∶ 1. Grossly,50 cases showed single or multiple cysts with the size 0. 5 ~ 8. 0 cm in diameter,which did not communicate with bronchial cavity. 18 cases showed honeycomb cysts with the diameter of 0. 1 ~ 2. 0 cm. 26 cases were solid lesions without visible cysts. 21 cases were observed lung abscess with thick and rough wall and pus inside. 7 cases of emphysema showed microcysts with crepitation. 2 cases were identified cystic and solid masses,with fish-fresh like cut surface. Histopathologically,94 cases( 75. 2%) were related to congenital bronchopulmonary dysplasia in 125 cases of CLD,in which there were 59 patients( 47. 2%) of congenial pulmonary airway malformation( CPAM),including 29 cases of type 1( 49. 2%),18 cases of type 2( 30. 5%),and 12 cases of type 4( 20. 3%),there were 26 cases( 20. 8%) of pulmonary sequestration,including 15 cases of intralobar type( 57. 7%) and 11 of extralobar cases( 42. 3%),5 cases were complicated with CPAM type 2,8 cases were bronchial cyst( 6. 4%) and 1 case of enteric cyst( 0. 8%). Acquired lesions were detected in 31 cases( 24. 8%),including 21 cases of infected lung abscess,1 case of fungal abscess. 7 cases of emphysema,and 3 cases of pleuralpulmonary blastoma( typeⅠ1 case and typeⅡ2 cases). Conclusion Pediatric CLD is characterized as complexed categories. The prognosis depends on correct pathological diagnosis,combined with imaging evaluation and appropriate timing of surgery.


Seroprevalences, risk factors and preventive measures are discussed on the basis of three seroepidemiological studies on the prevalence of antibodies against zoonoses of different persons (in farmers, veterinarians, slaughterhouse staff and hunters). A total of 635 volunteers (including a control group of 50 persons) from the above occupational groups were examined for the presence of antibodies to 25 zoonotic pathogens. Examples of zoonoses transmitted through animal handling are presented in the present work. Seroprevalences in the occupational groups examined were clearly higher than those obtained for the control group. Farmers, veterinarians, slaughterhouse staff and hunters must thus be considered as occupational groups that are predisposed to zoonoses.


Sorting by Exchanging We show that exchanging of pairs in an array which are in incorrect order leads to sorted array. It justifies correctness of Bubble Sort, Insertion Sort, and Quicksort.


The cylinder seals and seal impressions from Brak have an importance out of proportion to the quality of their workmanship. All the circumstances of their discovery are scrupulously recorded, a great help in determining the approximate date of each piece, and a sure guaranty against any suspicion of forgery. They may not all be of outstanding artistic merit, but a few seem to be unique in the choice of subjects reptesented, and almost every one of them can show some detail or peculiarity which is well worthy of study. Professor Mallowan in his catalogue describes and discusses these works of glyptic art, and his extensive knowledge of the subject, and his diligent researches enable him to make illuminating comparisons and to give suggestive explanations of the more difficult problems. He has, indeed, given us all the essential information and much more besides in his valuable and penetrating discussion. The seals, however, were only a small part of the immense mass of material which he, as excavator, had to set in order, study and describe. It is because his harvest is so rich and abundant that it seemed worth while to gather up stray gleanings dropped from his full sheaves, Knowing well that the few observations which can be contributed, will only render more evident the value and importance of what he has given us.


: The essays in this volume explore how writings have been stored and kept available for future use across time and space. They can be regarded as some of the first steps towards a cross-cultural and even global study of archives and archival practices. Taken as a whole, the papers indicate many of the topics (and difficulties) that would need to be addressed in a future global investigation of archives and archival practices. *


An image retrieval system is a piece of software that searches identical or similar images based on various image-specific features. This paper proposes a trademark image retrieval system that uses image colors and forms. In the proposed system. input images are segmented into several other regions, and color distribution histograms for different regions are extracted for use as color information. The proposed system uses form information through the preprocessing process such as boundary surface extraction, centroid extraction, angular sampling and, and through calculating the sums of the distances between the centroid and the boundary surfaces, standard deviations, and the ratios between long and short axes. Like this, the color and form information extracted is used to perform retrieval through measuring similarity.

����� RGUABLY, what many women regionalist writers did best was to Lrepresent the dramas of labor that structured domestic life: the tasks ofmanaging scarce resources and finding alternative ones, negotiating with uncomprehending or hostile patriarchal bosses, and conducting diplomatic and trade relations with other households. These dramas brought together the patriarchal politics of the household and the capitalist economics of the nation, inflected by the particular economic circumstances ofthe region under consideration and the general well-being ofthe rural population as a whole. In focusing either on the individual plights and satisfactions ofwomen characters in these works or on the potential of regionalist works to reduce rural populations to the nostalgic projections of urban audiences, the two most important traditions of scholarship about regionalism have overlooked this intriguing conjunction between the political economy ofhouseholds and the political economy of the nation. To explore this conjunction, I would like to analyze how some well-known wotks of New England women's regionalism functioned in relation to the ethic ofproducerism that grounded Populism. Populism's impact on U.S. politics and U.S. public thought in the 1890s can setve as an index of the centrality of rural spaces and rural populations in the national imagination, and therefore ofthe likelihood that regionalist fiction served important and complex political purposes.2 It is possible to argue that the mere dissemination of Populist ideas—


A series of aza-5[H]-phenanthridin-6-ones were synthesized and evaluated as inhibitors of poly ADP-ribose polymerase-1 (PARP-1). Inhibitory potency of the unsubstituted aza-5[H]-phenanthridin-6-ones (i.e., benzonaphthyridones) was dependent on the position of the nitrogen atom within the core structure. The A ring nitrogen analogues (7-, 8-, and 10-aza-5[H]-phenanthridin-6-ones) were an order of magnitude less potent than C ring nitrogen analogues (1-, 2-, 3-, and 4-aza-5[H]-phenanthridin-6-ones). Preliminary stroke results from 1- and 2-aza-5[H]-phenanthridin-6-one prompted structure-activity relationships to be established for several 2- and 3-substituted 1-aza-5[H]-phenanthridin-6-ones. The 2-substituted 1-aza-5[H]-phenanthridin-6-ones were designed to improve the solubility and pharmacokinetic profiles for this series of PARP-1 inhibitors. Most importantly, three compounds from this series demonstrated statistically significant protective effects in rat models of stroke and heart ischemia.


The study "Application of Factor and Cluster Analyses to Determine Source– Receptor Relationships of Industrial Volatile Organic Odor Species in a Dual-Optical Sensing System " by Jen-Chih Yang et al. uses FTIR spectroscopic measurements to determine the source of the emission of Volatile Organic Odor Species near an industrial park in southern Taiwan. The measurements are carried out at three sites (CY: a sun glass factory, KS: a light metal casing factory, NS: solar cell manufacturer), where the odor and contamination might be emitted and another where the odor and the related species are detected. Therefore in this study the composition of the stack emissions


An outbreak of poisoning by Sorghum halepense (L.) Pers. in cattle in the Brazilian semiarid is reported. Nine cattle were introduced 15 days after the first rains into a paddock where the plant was sprouting and had 25-30cm high. Clinical signs of dyspnea, anxiety, muscular tremors and incoordination appeared 15 minutes after the animals began to graze. Two of them died within about 3 hours. The others recovered. Cyanotic mucosa, dark muscles, lung edema and hemorrhages, and leaves of the plant in the rumen were observed at necropsy. The plant was positive for the picrosodic paper test. S. halepense from another farm of occurrence of the poisoning was transplanted into two pots. The picrosodic paper test was performed fortnightly in the plants growing in one of them. The plant was positive for cyanide in all growth stages; during the first 45 days the test was positive within 1 minute, but after day 60 within 3 minutes. Thirty days after the plant had been transplanted into one of the pots, it was administered to a goat at a dose of 11.8g/kg, causing clinical signs of HCN poisoning. The animal recovered after the intravenous administration of 5mL/10kg body weight of a 20% sodium thiosulfate solution. In the Brazilian semiarid S. halepense is frequently found invading the border of ponds and irrigated crops, and is used as forage during the dry season.


— Many environment specific methods and systems for Robot Navigation exist. However vast strides in the evolution of navigation technologies and system techniques create the need for a general unified framework that is scalable, modular and dynamic. In this paper a Unified Framework for a Robust Conflict-free Robot Navigation System that can be used for either a structured or unstructured and indoor or outdoor environments has been proposed. The fundamental design aspects and implementation issues encountered during the development of the module are discussed. The results of the deployment of three major peripheral modules of the framework namely the GSM based communication module, GIS Module and GPS module are reported in this paper.


We give a formulation of the ergodic theory of Banach space contractions which has as a special case Sine's finite dimension criterion for C(X). For Grothendieck spaces, a sharper condition for ergodicity of an operotor is given, and a known mean divergence theorem for G-spaces of type C(X) is shown to hold (in su itable form) for any G-space. Finally we show that for G-spaces ergodicity of T is closely related to that of the adjoint T*.


According to different purposes of motion simulations,taking the internal gear pairs as an example,this paper introduces in detail three types of motion simulations under UG software:parametric model simulation,high-quality picture simulation and UG/MOTION motion simulation.The parametric model simulation is mainly suitable to verify the shape of the tooth profile and accuracy of the assembly model;the high-quality picture simulation is limited only to obtain the time-based animation;but the UG/MOTION motion simulation is more advanced type of motion simulation to provide lots of data and chart results for simulation.The results demonstrate that the three types of motion simulations have different practical value in engineering.


This study was carried out from November to December 2012 to find out guild composition of birds in that place. The data collected by catching method, using mist nets as trapping equipment. Composition of guild was analyzed based on the number of individuals and species for every guild category to count the abundance values. Chi-square test was used to find out the interaction between the number of individuals or species and guild category. As a result, we got a total of 78 individuals of birds that belonging to 33 species and 9 guild categories. Insectivore-frugivore (IF) is category guild with the highest number found either for the total number of individuals or species, and the smallest number is the group of aerial frugivore (AF). The greatest of abundance values is IF category, described by the values obtained are 47.71% based on the total number of individuals and 21.21% based on the total number of species. While the lowest abundance values is AF, 1.28 % based on the total number of individuals and 3.03% based on the total number of species. The abundance values is not always directly proportional between the total number of species and individuals. Results of statistical analysis, there is no significant interaction between the total number of species and category of guild, while significant interaction are found between the number of individuals and guild category.


Coal bottom ash (CBA) is a by-product generated in the coal furnaces of thermal power plants. It has adverse effects on the environment and requires additional landfill storage. However, the physical appearance of CBA is similar to that of sand, with particle sizes ranging from fine to coarse aggregates. Hence, many previous studies have focused on its application instead of sand for conventional concrete and structural fill materials considering natural sand depletion. Roller compacted concrete (RCC) is a zero-slump concrete with better compressive strength than conventional concrete because of the aggregate interlock achieved due to the compactness. It uses a low cement content but requires a large amount of sand. However, the applicability of CBA to RCC is limited. The properties of CBA may vary depending on the location. Therefore, this study aims to evaluate the effect of CBA as a sand replacement in RCC in terms of strength and long-term performance by conducting an empirical experiment under given conditions. Initially, a comprehensive literature review of various concrete strengths using CBA as sand replacement is provided. Thereafter, details related to the experiments on the strength and durability of the given CBA are presented. The results show that the RCC strength improves when CBA increases owing to the good gradation and low percentage of calcium oxide. Furthermore, the samples displayed acceptable freeze–thaw resistance values, but the scaling resistance values were small, owing to the high-water absorption. Therefore, CBA can be used in RCC as sand for improved structural performance, while additional research should be conducted to improve its long-term performance.


Process of modifying of the surface layer of metals under influence of high-frequency electromagnetic field was considered using numerical simulation. The temperature field and the size of modified region were determined at various modes of processing.


A trickle‐bed air biofilter (TBAB) was evaluated under conditions of interchanging the feed volatile organic compounds (VOCs) in the sequence methyl ethyl ketone (MEK), toluene, methyl isobutyl ketone (MIBK), styrene, and then back to MEK. The obtained performance results revealed that the biofilter provided high removal efficiency within the critical loading of each VOC, which was previously defined in the non‐interchanging VOC fed biofilter. The biofilter easily acclimated to the oxygenated compounds (MEK and MIBK), but re‐acclimation was delayed for the aromatic compounds (toluene and styrene). Ratios of the molar mass of CO2 produced per molar mass of VOC removed were investigated. It has been found that the ratios for the aromatic compounds closely resembled the theoretical complete chemical oxidation based ratios while larger differences were encountered with the oxygenated compounds. Denaturing gradient gel electrophoresis (DGGE) analysis of 16S rRNA genes was used to assess the impact of interchanging VOCs on the bacterial community structure in the biofilter. The results from denaturing gradient gel electrophoresis (DGGE) showed that the structure of the microbial community in the biofilter was different after each interchange of VOCs.

Background: Altering the weight of baseballs for youth play has been studied out of concern for player safety. Research has shown that decreasing the weight of baseballs may limit the severity of both chronic arm and collision injuries. Unfortunately, reducing the weight of the ball also increases its exit velocity, leaving pitchers and nonpitchers with less time to defend themselves. The purpose of this study was to examine impact probability for pitchers and nonpitchers. Hypothesis: Reducing the available time to respond by 10% (expected from reducing ball weight from 142 g to 113 g) would increase impact probability for pitchers and nonpitchers, and players' mean simple response time would be a primary predictor of impact probability for all participants. Study Design: Nineteen subjects between the ages of 9 and 13 years performed 3 experiments in a controlled laboratory setting: a simple response time test, an avoidance response time test, and a pitching response time test. Methods: Each subject performed these tests in order. The simple reaction time test tested the subjects' mean simple response time, the avoidance reaction time test tested the subjects' ability to avoid a simulated batted ball as a fielder, and the pitching reaction time test tested the subjects' ability to avoid a simulated batted ball as a pitcher. Results: Reducing the weight of a standard baseball from 142 g to 113 g led to a less than 5% increase in impact probability for nonpitchers. However, the results indicate that the impact probability for pitchers could increase by more than 25%. Conclusion: Pitching may greatly increase the amount of time needed to react and defend oneself from a batted ball. Clinical Relevance: Impact injuries to youth baseball players may increase if a 113-g ball is used.


When the Deepwater Horizon oil spill occurred in 2010, the story was mostly front and centre at major news sources. The disaster's aftermath is still ongoing, and the nature of oil corporation BP's profit driven carelessness rattles those in the environmental movement to this day. But the oil spill that occurred in Texas City, Tens, and which has largely affected Galveston Bay, has Down under the radar. Though smaller when it came to the amount of spillage, the incident may grow to be just as large in scope and damage. with everything and everyone from wildlife to workers currently paying the price.


Separating convolutive mixtures of source signals is a challenging blind source separation (BSS) problem. A new approach for convolutive mixtures BSS by exploiting the householder transformation to realize the joint diagonalization of high-order cumulant and operating in the frequency domain is proposed. The frequency domain algorithms have a simpler implementation than the time domain algorithms. Joint diagonalization of the fourth-order cumulant in high-order cumulant is operated through using the householder transformation, which can simply and faster implement the joint diagonalization of the matrices. The numerical computer simulations are presented to illustrate the validity and feasibility of our algorithm.


Purpose
The presence of ferrous wear debris in lubricating oil may cause progressive damage in the internal combustion engines. Online monitoring of the size and concentration of these particles in the oil is a way to optimize the engine performance and its life cycle.

Design/methodology/approach
In this study, an online sensor was designed and fabricated to identify ferrous wear particles in the engine oil based on the induction method. The diameter of the sensor outlet duct was designed as small as possible to generate a high-intensity magnetic induction and achieve a proper sensitivity in the sensor. The experiments were designed and performed in offline mode. Furthermore, to evaluate the actual performance of the sensor in presence of iron particles in the oil, online tests were performed at different sizes and concentrations.

Findings
It was concluded from offline tests that the highest sensitivity of the sensor occurs at the frequency and voltage of 2.5 kHz and 120 V, respectively. According to the results of the online tests, the larger the particle size, the higher the peaks at the sensor output. Also, a high density of the peaks was observed in the sensor output graphs as the concentration of particles was increased.

Originality/value
The proposed sensor was able to identify ferrous wear particles larger than 125 µm separately, which is the failure limit in the internal combustion engines.

These loaders are known for their light weight and their versatility in handling jobs that are traditional tackled by skid-steer loaders. Rubber tracks, easy maneuverability, high lift, long reach, quick-attach mounting capabilities, high flow, high speed, and low ground pressure are some of the features these compact loaders offer.


We propose a terrestrial detector for gravitational waves with frequencies between 0.3 Hz and 5 Hz. Therefore, we discuss a symmetric matter-wave interferometer with a single loop and a folded triple-loop geometry. The latter eliminates the need for atomic ensembles at femtokelvin energies imposed by the Sagnac effect in other atom interferometric detectors. It also combines several advantages of current vertical and horizontal matter wave antennas and enhances the scalability in order to achieve a peak strain sensitivity of $2\cdot10^{-21}\,/\sqrt{\mathrm{Hz}}$.


Based on the dynamic triaxial experiment of a core wall asphalt concrete,this paper studies the influences on its dynamic characteristics by factors of confining pressure,consolidation ratio,bitumen aggregate ratio,etc.The results show that an increase in confining pressure or consolidation ratio is conducive to its capabilities of resisting dynamic loads,but such an increase leads to a reduction in its damping ratio.The bitumen aggregate ratio has a great influence on the dynamic properties.In the test range of asphalt concrete mixing proportion in this study,an increase in bitumen aggregate ratio considerably improves the resistance of asphalt concrete against dynamic loads.


Until now, Philip Grierson's tentative dating of Charlemagne's monetary reform to 793/4 has been generally accepted. His dating was based not only on numismatic evidence but also on his attempt to set this event in the context of Charlemagne's activities from 792 to 794. This traditional date of the reform does not, however, take into account evidence provided by Codex Sangallensis 731, in which the scribe Wandalgarius drew the image of a post‐reform coin around mid‐October 793. Based on this evidence as well as the historical contextualization of Charlemagne's stay in Regensburg in 791–3, this paper attributes the introduction of the novi denarii to the period between the autumn of 792 and the early autumn of 793, when his court was located in Regensburg.


This paper explores the relationship between Marketing and Artists and proposes that it is a relationship that is beneficial to both parties. Once there was a perception that art must be non-commercial to be considered art. This does not take into account that art must be recognized and accepted by society to attain the value and recognition [1] the artist desires. We postulate that this acceptance can be gained by exposure through marketing as well as traditional artistic avenues. Examples are given of how some of the most famous art today became famous not because of the artistry, but because of an external force unrelated to the art. We examine 4 artists – Warhol, Lautrec, Rockwell and Steinlen – who are as famous, or even more famous, due to their commercial art. Examples are given of how some of the most famous art today became famous not because of the artistry but because of an external force unrelated to the art. We examine 4 artists – Warhol, Lautrec, Rockwell and Steinlen – who are as famous, or even more famous, due to their commercial art. Would Lautrec or Steinlen ever have been heard of if not for their iconic poster ads of the late 1800's? And while Warhol and Rockwell didn't become famous for advertising exactly, Warhol gained fame by painting a can of soup, and Rockwell was best known for his Saturday Evening Post covers. Art and marketing are natural allies.


The aim of the article is to define the status of political correctness in the Polish language and its re-lationship with linguistic politeness. An important element is to describe the various approaches and attempts to define political correctness and to reflect on the ideologization of the studied phenomenon. The first step is to develop a theoretical basis, discussing the issue of linguistic politeness and political correctness. In the next part, both phenomena are confronted and their relationships are discussed via the example of the lexeme Murzyn (Black). The analysis of the problem showed the ideological entangle-ment of political correctness and a negative evaluation of this phenomenon, despite the assumptions convergent with linguistic politeness, which does not raise objections from language users.
