Dynamic stiffness method in the vibration analysis of circular cylindrical shell

In this paper the dynamic stiffness method is used for free vibration analysis of a circular cylindrical shell. The dynamic stiffness matrix is formulated on the base of the exact solution for free vibration of a circular cylindrical shell according to the Flugge thin shell theory. The matrix is frequency dependent and, besides the stiffness, includes inertia and damping effects. The derived dynamic stiffness matrix is implemented in the code developed in a Matlab program for computing natural frequencies and mode shapes of a circular cylindrical shell. Several numerical examples are carried out. The obtained results are validated against the results obtained by using the commercial finite element program Abaqus as well as the available analytical solutions from the literature.
Male Infertility; Evidences, Risk Factors, Causes, Diagnosis and Management inHuman

Infertility has become ominous problem. On an average, about 10% of all couples face difficulty in starting a family and this creates a feeling of great personal failure, particularly in India where religious and socio-economic traditions have made it almost imperative for everyone to have children. A significant association had been found between impaired semen quality including sperm count, motility and morphology. In this review, the various contributory etiological factors i.e., exposure to heavy metals, pesticides, industrial chemicals, endocrine factors, genetics causes and modern life style had been discussed which have a serious impact on male infertility. In this article we analyzed data from different sources and present evidences of the possible etiology and risk factors for male infertility. There is a need to emerge at the indiscriminate use and disposal of environmental chemicals. Especially pesticides and industrial chemicals as the chemicals enter the food chain, surface and ground water which had potential for exposure during the critical period of development further avoiding tobacco smoking, excessive alcoholism, excessive heat exposure to the testes can help in improving the semen quality.
Labial Dissimilation as an Amazigh Substratum in Moroccan Arabic

The paper is an attempt to provide evidence for the existence of an Amazigh substratum in Moroccan Arabic by considering the way labial and round dissimilatory processes are woven in the language. In particular the paper seeks to explain within the constraint-based framework of Parallel Optimality Theory that labial/round dissimilation is a contact-induced phenomenon resulting from the influence of Moroccan Amazigh and as such prior knowledge of this language seems to be a prerequisite for a thorough understanding of the dissimilation process in Moroccan Arabic.
Multiliterate Star Warians: The Force of Popular Culture and ICT in Early Learning

CAN POPULAR CULTURE AND information communication technologies (ICT) broaden early years' multiliteracies experiences? This paper presents a case study that begins with boys role-playing Star Wars action scenes at the commencement of the school year, and concludes with an end-of-year school community celebration of a new DVD Star Wars movie sequel, designed and performed by the boys. The Children's Star Wars Project was developed in a small Western Australian independent community school committed to the Reggio Emilia educational philosophy. The case study provides an exemplar of the integral relationship between early childhood pedagogy, multiliteracies metalanguage, and multimodal designs of meaning. Implications for educational research are that popular culture and ICT can be readily integrated with early childhood education (ECE) to broaden multiliteracies experiences. As shown in this case study, these experiences facilitate the achievement of The Early Years Learning Framework for Australia outcomes.
The Antifungal Activity of Bee Venom against Dermatophytes

The antifungal activities of the bee venom against Trichophyton mentagrophytes and Trichophyton rubrum were determined by using modified broth dilution assay. The most common dermatophytes, named T. mentagrophytes and T. rubrum, were known to cause a variety of cutaneous infections in humans and animals. The bee venom exhibited prominent antifungal activities against the two dermatophytes tested in this investigation. Moreover, the antifungal activities of the bee venom were much stronger than that of fluconazole, one of the commercial antifungal drugs used in the treatment and prevention of superficial and systemic fungal infections. The result suggests that bee venom could be developed as a natural antifungal drug.
Cycles on curves and Jacobians: a tale of two tautological rings

We connect two notions of tautological ring: one for the moduli space of curves (after Mumford, Faber, etc.), and the other for the Jacobian of a curve (after Beauville, Polishchuk, etc.). The motivic Lefschetz decomposition on the Jacobian side produces relations between tautological classes, leading to results about Faber’s Gorenstein conjecture on the curve side. We also relate certain Gorenstein properties on both sides and verify them for small genera. Further, we raise the question whether all tautological relations are motivic, giving a possible explanation why the Gorenstein properties may not hold.
Interruption Management for Hospital Communications Systems A user requirements study

Working in a hospital environment requires highly mobile personnel. To facilitate the increasing need for exchange of patient data between healthcare professionals, mobile communication devices are used. Mobile communication devices also increase the occurrence of inappropriate interruptions during clinical task performance. These interruptions have been related to decreased quality of clinical care. User requirements were elicited using a scenario- based approach. The results present insights into user requirements for an interruption management system for hospitals. Hospital workflow protocols were identified as a major source of interruptions. Suggestions by participants for managing these interruptions related to improving workflow using IT instead of merely preventing interruptions. We have shown that even though the hospital is an exceptionally demanding environment, the user requirements for interruption management concur with earlier findings in the broader fields of context aware interruption management and computer supported cooperative work.
Sustainability and CALL: Factors for success in a context of change

A team of university Italian teachers at an Australian university has been able to obtain enduring benefits from CALL, through projects that last, and indeed grow and develop over time. The projects have focused on supporting students in effective use of out-of-class time once they reach an intermediate level of proficiency. This paper analyses the team’s 15 years of CALL experience by first examining the opportunities and constraints of the changing technological context—with rapid developments in both the types of tools available and the students’ relationships to them—and then seeking to identify aspects of the team members’ role as agents in that context that have allowed the projects to be successful despite the challenges. While we acknowledge that a certain level of skills, ability to work as a team and institutional support have been essential, we stress that the key to the success lies in three key principles that shape the team’s approach, namely: tailoring, integration and an iterative development process. Recommendations follow on strategies and techniques that we believe will assist in the sustainability of CALL over the long term in a university setting.
Results of cross-border mergers and acquisitions by multinational enterprises from emerging countries: the case of Poland

In recent years, a noteworthy number of huge mergers and acquisitions involving firms from both advanced and emerging economies took place. The determinants of such transactions have been frequently revealed and the motives were to a certain extent apparent. However, the real results of these transactions have not been widely recognised. This paper has been devoted to the analysis of the financial effects of mergers and acquisitions abroad by firms from an emerging country, that is, Poland. I analyse several financial performance indicators of acquiring enterprises: revenues, gross profit, ROE, ROA. The time span of the analysis includes both periods proceeding and consecutive the transactions. The main conclusion drawn from the comparative analysis is that firms that took over a stake in a foreign firm or a complete business abroad where better off in absolute terms, but their financial ratios were weaker.

Effect of a bacteriophage cocktail in combination with modified atmosphere packaging in controlling Listeria monocytogenes on fresh-cut spinach

Abstract A Listeria monocytogenes-specific bacteriophage cocktail was evaluated for its activity against a nalidixic acid-resistant L. monocytogenes (Lm-NalR) isolate on fresh-cut spinach stored under modified atmosphere packaging at various temperatures. Pieces (~2 × 2 cm2) of fresh spinach inoculated with 4.5 log CFU/cm2 Lm-NalR were sprayed with the phage cocktail (6.5 log plaque-forming units [PFU]/cm2) or a control. The samples were stored at 4°C or 10°C for up to 14 d in sealed packages filled with either atmospheric air (AA) or modified atmosphere (MA). At 4°C under AA, the phages significantly (P ≤ 0.05) lowered the Lm-NalR populations on spinach, compared to control-treated inoculated samples, by 1.12 and 1.51 log CFU/cm2 after 1 and 14 d, respectively. At 4°C under MA, Lm-NalR was significantly reduced by 1.95 log CFU/cm2 compared to control leaves after both 1 and 14 d. At 10°C under AA, the phages significantly reduced Lm-NalR by 1.50 and 2.51 log CFU/cm2 after 1 and 14 d compared to the control. Again at 10°C under MA, the phages significantly reduced Lm-NalR by 1.71 and 3.24 log CFU/cm2 compared to control after 1 and 14 d, respectively. The results support the potential of lytic bacteriophages in effectively reducing populations of L. monocytogenes on freshcut leafy produce, under both AA and MA conditions.
Evaluation of Campus Police Officers in Scottish Schools

Ipsos MORI were commissioned by the Scottish Government to conduct an independent national evaluation of campus officers 1 in Scotland. The research used a mixed method case study approach to explore the roles that officers play in Scottish schools and provide evidence on the impact and effectiveness of their placements. A best practice guide was created to help local decision makers through the process of deployment and the practicalities of placing an officer in a school. This document summarises the findings of the evaluation.
Business sustainability through employees involvement: A case study

Business sustainability is dependent on many factors but one of the most uncontrollable factor is employee's involvement and collaboration. Frequently employees are working and acting like 'androids' day-after-day, repeating the same routines with no motivation or enthusiasm, feeling that any requests would not be attended by their supervisors. The objective of this paper is to present how some simple ideas could connect and involve employees and supervisors in a continuous improvement journey in an inbound logistics area of an automotive sector company. The new ideas were implemented through an action-research methodology. Results achieved included new ideas and contributions for the problems (59 problems identified) of their sector promoting the company's financial and social sustainability.
Relationship between free cash flow and dividend: Moderating role of firm size.

In this study we want to examine the relationship between free cash flow and dividend in presence of a moderator firm size. Results indicate proxies of free cash flow have positive and highly statistically significant relationship with free cash flow. Second model of moderator showed results insignificant with relationship between FCF and dividend. In simple regression of free cash flow and dividend, results were also insignificant which also indicate that there is no relationship in these variables. In our study we have used panel data analysis and to check the time and cross sectional effect, dummies has used. The results were highly statistically significant across the mostly companies and free cash flow but only two companies showing insignificant results. The results were insignificant across different periods. Our hypothesis was rejected under moderator but acceptable in fixed effect model.
Chapter V Integrating Knowledge of Cognitive System and E-Learning Applications

This chapter outlines key findings of cognitive and developmental psychology which could be used as a theoretical framework to guide the design and research of e-learning applications. The chapter consists of two main sections. The first section presents the basic cognitive mechanisms and their de velopment, while the second part discusses how our knowledge of the cognitive system can guide the design of computer-based learning environments. It is proposed that the human mind is organized in three levels: two of them are general-purpose mechanisms and processes and one consists of domainspecific structures of knowledge representation and problem solving processes. These three levels are associated with an effective learning framework. The suggested framework describes the basic points that any designer of e-learning environments must consider. The second section of the chapter discusses e-learning, connecting it to knowledge about the human cognitive system. In this section, we first present the conceptual bounds of the e-learning construct and discuss how cognitive theories of learning should guide the design of technologically-enhanced learning environments. It is proposed that a synergy between the study of human cognition and the design of e-learning applications is required for effectively understanding both fields.

The theory-based conceptions of categorization postulate the existence of a network of causal relations between the features involved in object representations and consider that this network underpins both judgments of category membership and inference production. The aim of this article is to examine the proposed models (causal status, causal density) within the framework of theory-based conceptions and indicate how they account for inferential processes. Finally, we underline the importance of the task context, and of the role of the nature of the ontological domain for the theoretical modeling of a causal network based on an asymmetrical, probabilistic representation of causality. Les theories de la categorization fondées sur les connaissances postulent l’existence d’un réseau de relations causales entre les traits impliqués dans les representations d’objets et que ce réseau sous-tend à la fois les jugements d’appartenance catégorielle et les inferences. Cet article se focalise sur les processus d’induction. Son but est d’examiner les modèles proposés pour rendre compte des processus inférentiels (modèle du statut causal, de la densité causale). Nous soulignons l’importance du contexte de la tâche et de la nature du domaine ontologique dans une modélisation théorique d’un réseau causal, basé sur une représentation multidéterminée et asymétrique de la causalité.
The role of FasR/FasL system in pathogenesis of myeloprolyferative neoplasms

Myeloproliferative neoplasms (MPN) are hematological malignancies characterized by uncontrolled cell proliferation and impaired apoptosis. The FasR/FasL system is involved in the control of apoptosis in different cell types. Here we have investigated the role of FasR/FasL in the pathogenesis of MPNs. We compared FasR/FasL expression between MPN patients (24) and healthy individuals using the real-time PCR assay. We found an increase of FasR expression in MPN patients. No difference was detected in FasL expression. Mutation V617F in the JAK2 gene, a hallmark of MPN, was detected in 13/24 patients. We found that neither FasR nor FasL expression were related to the presence of JAK2 V617F mutation.
Resistance and Phenotypic Character of Chili M2 Mutant Lines Against Chilli Veinal Mottle Virus

Chilli veinal mottle virus infection (ChiVMV) could reduce the quality and 60–100% of yield losses of chili. Among the chili varieties released, no one has been resistant to ChiVMV, mainly due to a high variation of ChiVMV strains and not well mapped. Therefore, finding a new source of ChiVMV resistant genes is pivotal role in order to assembly new varieties. Approach through in vitro mutation induction using mutagen ethyl methane sulfonate (EMS) is one of the efforts to increase genetic diversity. Previous studies has successfully acquired 800 M2 lines through callus induction of Gelora variety with EMS. This study aimed to obtain M2 lines resistant to ChiVMV and having a good agronomical characters. A total of 800 chili M2 lines that derived from chili M2 mutations using mutagen EMS has been tested in greenhouse to ChiVMV resistance and studied character phenotype. The results showed that of the 800 lines, there were 28 strains obtained showed a response tolerant and resistant to ChiVMV. Eight mutant lines of which have good agronomic characters. The mutant lines are M2.100, M2.108, M2.200, M2. 122, M2.238, M2.353, M2.420, and M2.517. Eight lines will be selected and further observed to obtain chili promising lines that are resistant to ChiVMV and high yielding.
The impacts of commercial woodland management on woodland butterfly biodiversity in Morecambe Bay, UK

Although the effects on biodiversity in woodland managed for conservation have been studied for a range of species, there is very little empirical data on the potential impacts of commercial woodland management on biodiversity in the UK. This study measured species richness and abundance of diurnal butterflies as a proxy for the habitat quality of three different woodland management techniques in the Morecambe Bay limestone woodland region. Butterflies were sampled at two sites; Gait Barrows and Witherslack, where three woodland management techniques were carried out: low management woodland (woodland with no recent intervention); traditional coppice management for conservation; and commercial woodland management. Both coppice management for conservation and commercial management had significantly higher butterfly species richness and abundance when compared to low management woodland; neither butterfly species richness nor abundance were significantly different between the traditional coppice management for conservation and commercial woodland management. UK Biodiversity Action Plan fritillary species (high brown fritillary Argynnis adippe; pearl bordered fritillary Boloria euphrosyne; and small pearl bordered fritillary Boloria selene) were not significantly different between the traditional coppice management for conservation and commercial management.
Polyphenolic Characterisation of Vranac, Kratosija and Cabernet Sauvignon (Vitis vinifera L. cv.) Grapes and Wines from Different Vineyard Locations in Montenegro

In Montenegro, red wines are produced predominantly, and Vranac accounts for nearly 80% of these wines, followed by Kratosija and Cabernet Sauvignon. In order to characterise polyphenols in red varieties, grapes were sampled from representative vineyards at harvest time during 2011 and 2012. The content and distribution of extractable anthocyanins, low-molecular mass proanthocyanidins (LMP) and highmolecular mass proanthocyanidins (HMP) in the seeds and skins of the grape berries were evaluated by applying a five-day extraction method using ethanol:water (12:88) as extraction solvent. On average, the highest content of LMP (2 006 and 1 690 mg/kg of grape fresh mass in years 2011 and 2012 respectively), HMP (2 705 and 2 805 mg/kg in years 2011 and 2012 respectively) and anthocyanins (1 035 mg/kg in the year 2011) was found in the Cabernet Sauvignon grapes. The highest content of anthocyanins (1 113 mg/kg in the year 2012) and the lowest content of LMP (1 103 and 846 mg/kg in years 2011 and 2012 respectively) was found in Vranac grapes. Kratosija grapes had the lowest anthocyanin content (456 and 517 mg/kg in years 2011 and 2012 respectively), and levels of LMP were similar to Vranac. The percentage distributions of LMP between skins and seeds were 34:66, 39:61 and 49:51, whereas the distributions of HMP between skins and seeds were 67:33, 62:38 and 64:36 for Vranac, Kratosija and Cabernet Sauvignon respectively. All varieties had more LMP in the seeds and more HMP in the skins of the grapes. The results obtained are important to better understand the polyphenolic potential of Montenegrin red grape varieties.
9. PETROGRAPHY AND PROVENANCE OF VOLCANICLASTIC SANDS RECOVERED FROM THE IZU-BONIN ARC, LEG 1261

Modal compositions of volcaniclastic sands recovered on Leg 126 of the Ocean Drilling Project (Izu-Bonin island arc and Sumisu Rift) are similar to those from other intraoceanic island arcs and associated marginal basins. These sands are dominantly composed of volcanic-lithic and plagioclase-feldspar grains derived from the Izu-Bonin magmatic arc and intrarift volcanoes. The glass color of volcanic fragments ranges from black (tachylite) to brown to colorless; individual samples usually contain a mixture of glass colors. Two of the forearc sites (792 and 793) are more heterogeneous with respect to glass color than the backarc/Sumisu Rift sites (788, 790, and 791). Site 787 forearc sands are dominantly composed of tachylite grains; their unique composition may be attributed either to winnowing by submarine-can yon currents or to a volcanic island source. There is an increase in the proportions of pumice/colorless glass, felsitic grains, and quartz within sediments of the incipient backarc basin (Sumisu Rift), as compared with the forearc-basin sites.
ANALYSIS AND NUMERICAL SOLUTION FOR MULTI-PHYSICS COUPLING OF NEUTRON DIFFUSION AND THERMOMECHANICS IN SPHERICAL FAST BURST REACTORS

Coupling neutronics to thermomechanics is important for the analysis of fast burst reactors, because the criticality and safety study of fast burst reactors heavily depends on the thermomechanical behavior of fuel materials. For instance, the shut down mechanism or the transition between super and sub-critical states are driven by the fuel material expansion or contraction. The material expansion or contraction is due to temperature gradient which results from fission power. In this paper, we introduce a numerical model for coupling of neutron diffusion and thermomechanics in fast burst reactors. We also provide some analysis of the coupled system. We studied material behaviors corresponding to different levels of power pulses.
