A Versatile Hardware for Advanced Encryption Standard

Nowadays, the Advanced Encryption System - AES is used in almost all network-based applications to ensure security. The core computation of AES, which is performed on data blocks of 128 bits, is iterated for several rounds, de- pending on the key size. The strength of AES is proportional to the number of rounds applied. So far, the number of rounds is fixed to 10, 12 and 14 for a key size of 128, 192 and 256 bits respectively. Most cryptographers feel that the margin between the number of rounds specified in the cipher and the best known attacks is too small. On the other hand, it is clear that the overall efficiency of a given AES implementation is inversely proportional to the number of rounds imposed. In this paper, we propose a very efficient pipelined hardware implementation of AES-128. Besides, we show that if the re- quired number of rounds must increase to defeat attackers, the proposed implementation stays efficient.
The Effects of Social Capital on Team Performance: A study of RD Departments in Uzbekistan

The aim of the investigation was to explain impact of various dimensions of social capital on cooperation. In the attempt we constructed a research model by utilizing social capital theory. Ultimately cooperation within research and development teams in textile industry in Uzbekistan was assessed. A survey method was applied and a questionnaire was developed and administered to. Structural Equation Modelling together with multiple regression was used to test the predictive value of our model on the sample of 170 Research and development department members. Findings suggest there is a large positive impact of social capital on cooperation. Therefore, the study confirms the value of social capital in explaining cooperation. The study helps managers and team members to better understand the importance of social capital generation on projects and in organizations. The developed concept can be used as a framework for facilitating cooperation for governments, research institutions, academic institutions and companies.

The acceptance of microblogging in the learning process: The µBAM model

Microblogging social networks (µBSNs) provide the opportunity to communicate worldwide while using a small number of characters; this is an apparent limitation that forces users to share only essential information when linking to the world with which they interact. These platforms can serve to motivate students by narrowing the physical and psychological distances separating teachers and students, thus increasing their confidence and engagement in the learning process. The main thrust of this paper is the notion that µBSNs open a window to informal knowledge, self-directed learning and the creation of knowledge-based networks for use in a classroom setting. To examine this issue in greater depth, an experiment was carried out using a µBSN before, during and after face-to-face class sessions. In this study we used the Technology Acceptance Model (TAM), incorporating some of the constructs commonly found in the scientific literature. These constructs refer to the effect of subjective norms and social images on the use of web-based social networks. The analysis gave rise to a robust and parsimonious model of social network usage behavior that confirmed the proposed research hypotheses. The findings demonstrated that the extended TAM model is suitable for explaining the acceptance of web-based teaching tools as well as the validity of microblogging networks in combination with traditional classes.
Children's Eligibility for Medicaid and SCHIP: A View from 2000

Using eligibility rules in place as of July 2000, 57 percent of uninsured children were eligible for Medicaid and an additional 26 percent were eligible for SCHIP. Only 23 percent of uninsured children were not eligible for public health insurance coverage. Among low-income uninsured children, only 16 percent were not eligible for Medicaid or SCHIP. The authors conclude that lack of eligibility for public health insurance coverage is no longer the reason for uninsurance for most children. The challenge for policymakers is to focus on eliminating other barriers to enrollment for the millions of eligible but uninsured children. The analysis is based on the National Survey of America's Families and a detailed Medicaid and SCHIP eligibility model.
A stakeholder approach to international and national sport sponsorship

Purpose – Using a stakeholder perspective, this paper aims to investigate the effectiveness of sponsorship as a business investment by assessing the impact of sponsorship announcements on the shareholders' reactions of the sponsoring firms. These reactions are examined in two different occasions: in an international mega sport event such as the Olympic Games and in sport organizations such as sport federations/associations.Design/methodology/approach – Event study analysis by using multiple regression models and bootstrapping techniques were employed to study the effects of sponsorship announcements. The sample consisted of sponsors of the 2004 Olympic Games and sponsors of national sport federations.Findings – Overall, the results of the study did not indicate any significant effects of sponsorship announcements on the stock prices of sponsoring firms, suggesting that shareholders' reactions to this business activity are limited.Originality/value – This is the first research initiative that utilizes a st.
Prevalence of odontogenic deep neck space infections (DNSI): a retrospective analysis of 76 cases of DNSI

Background: Deep Neck Space Infections (DNSI) are serious diseases that involve several spaces of neck. Commonest sources of DNSI are dental and oropharyngeal infections. With widespread use of antibiotics, the prevalence of DNSI has been reduced but odontogenic DNSI are still common due to poor oral hygiene. Management mainly comprises of airway management, antibiotic therapy and surgical intervention. This study was conducted to find out the prevalence, distribution, presentation, sites involved, bacteriology and management of odontogenic DNSI. Methods: This retrospective study was done from October 2010 to January 2013 and included 76 patients with DNSI. Then, etiological factors of DNSI were studied and prevalence of odontogenic DNSI was calculated. All parameters including age, sex, co-morbidities, presentation, site, bacteriology and interventions required in odontogenic DNSI cases were studied. Results: Odontogenic infections were the most common etiological factor in DNSI, with a prevalence of 34.21% among DNSI. Toothace was commonest symptom, followed by neck swelling, pain and odynophagia. Submandibular space involvement (42.30%) was the most common clinical presentation of odontogenic DNSI patients, followed by Ludwig’s angina and masticator abscess. Conclusions: DNSI are common and life threatening infections. For management, early diagnosis is essential. In developing countries majority of DNSI are of odontogenic origin. In our country lack of adequate nutrition, poor orodental hygiene, tobacco and beetle nut chewing and smoking has increased the prevalence of odontogenic DNSI. So, prevention of odontogenic DNSI can be achieved by making population aware of oral and dental hygiene and by conducting regular check-up camps at community level.
Response of cyanobacteria to the fountain-based water aeration system in Jeziorak Mały urban lake

Abstract This study of cyanobacteria phytoplankton was conducted from May to August in 2002, 2003 and 2005 during fountain-based water aeration in the pelagial of the Jeziorak Mały urban lake in Poland. Additional water mixing by this installation’s activity changed the cyanobacterial growth conditions. Although less of their proportion was noted in total phytoplankton abundance, higher mean abundance and biomass were recorded at the fountain than at the lake centre. Higher water temperature in the surface layer favoured cyanobacterial growth at the fountain, while higher iron concentration stimulated their development in the lake’s centre. This was supported by positive correlations between their abundance and these water parameters. Moreover, the fountain’s activity contributed to the cyanobacteria sinking in the water column. The higher abundance of cyanobacteria was found at 1m depth in May, July and August than in the fountain surface layer. Additional water mixing during fountain activity caused also a shift in their abundance maximum (C - June and F - August) and contributed to intensive organic matter decomposition. These conditions promoted cyanobacterial nutrient uptake from the water at the fountain, and this is supported by the negative correlation between their abundance and orthophosphate and total nitrogen concentrations. Generally, water mixing during the fountain’s activity does not inhibit the growth of cyanobacteria. This phenomenon disturbed abundance dynamics of the cyanobacteria in summer months but didn’t contribute to their abundance decrease. It is important for these results to be considered in future management of shallow urban lakes.
Influence of Modified Atmosphere Packaging (MAP) on textural properties of Mozzarella cheese during refrigeration storage

The study was conducted to assess the textural quality of mozzarella cheese using MAP. 300 g of mozzarella cheese was placed in high barrier bags under five different atmospheres viz., air (atm 1), vacuum (atm 2), 100 % CO2 (atm 3), 100 % N2 (atm 4) and a mixture of 50% N2 and 50% CO2 (atm 5). Periodically, the product was evaluated for its textural quality with respect to its hardness, cohesiveness, gumminess, chewiness and springiness. Among the different modified atmospheres studied, atm 3 showed minimum changes on the textural quality in MAP Mozzarella cheese during storage, thus proving to be the best, followed by the samples packed in atm 5, atm 4, atm 2 and atm 1 respectively, in descending order. The five types of atmospheres and the intervals of storage period, each individually, influenced the textural quality of Mozzarella cheese.
Repeated Oral Administration of Aqueous Leaf Extract of Moringa oleifera modulated immunoactivities in Wistar Rats

The immunomodulatory capability of aqueous leaf extract of Moringa oleifera was investigated in male Wistar rats. Dry leaf powder of Moringa oleifera was extracted with water and lyophilized. Twenty four Wistar rats with body weight of 86.2 ± 4.43 g were grouped equally into four (A-D) and distilled water, 250, 500 and 1000 mg/kg body weight of extract were orally administered once daily for 56 days groups respectively. Serum interleukin-2 concentration increased (p<0.05), while interleukin-6 and tumour necrosis factor-? reduced (p<0.05). Erythrocyte parameters, neutrophils and monocyte concentrations were reduced (p<0.05). Total leukocyte and lymphocyte counts, and liver reduced glutathione were increased (p<0.05), while malondialdehyde and serum uric acid were decreased (p<0.05). The findings of this study supported the folkloric use of the aqueous leaf extract of Moringa oleifera as an immunomodulating regime for the prevention and/ or cure of infective and degenerative diseases. However, the extract caused anaemia. Keywords: Immunomodulatory capability, Moringa oleifera , supported, folkloric use, degenerative diseases and anaemia.
Microbial plankton response to contrasting climatic conditions: insights from community structure, productivity and fraction stoichiometry

Climatic events are among the most important forces governing natural processes in ecosystems. Over a 3 yr period, we monitored changes in the hydrological, chemical and biological regimes of a high mountain lake severely affected by a drought that peaked in 1995. During the drought, the decrease in lake volume enhanced the contribution of the sediment to the lake nutrient budget. The community became more complex, with the appearance of ciliates and heterotrophic nanoflagellates, organisms rarely found prior to the drought. The impaired post-drought recovery of the zooplankton, which did not reach normal densities for this lake until 1997, resulted in a microbial- dominated food web in 1996 and a classical grazing food web in 1997. Besides the species composi- tion or abundance and the autotrophic to heterotrophic ratio, food web changes associated with the drought and atmospheric nutrient inputs were reflected in the stoichiometry and contribution of both bacteria and phytoplankton fractions to the planktonic particulate matter. Specific productivity mea- surements showed that cellular N:P ratios could be used to evaluate the growth conditions of phyto- plankton but not of bacteria, indicating that an element other than P may limit bacteria growth. Assessments of phytoplankton and bacteria productivity and of the photosynthetic carbon release rel- ative to bacteria demand in microcosms revealed that after a phosphorus pulse, the phytoplankton N:P ratio determines the nature of the interaction between phytoplankton and bacteria as either com- mensalistic or competitive for inorganic P. If phytoplankton N:P is initially high (P-deficient algae), a P pulse can reduce photosynthetic extracellular release (PER) and bacteria can experience C limita- tion, whereas if phytoplankton N:P is initially low (P-sufficient algae) and bacteria N:P is high, increased PER is observed and competition for inorganic P may occur.
Lithium abundances and extra mixing processes in evolved stars of M 67

Aims. We present a spectroscopic analysis of a sample of evolved stars in M 67 (turn-off, subgiant and giant stars) in order to bring observational constraints to evolutionary models taking into account non-standard transport processes. Methods. We determined the stellar parameters (Teff ,l ogg ,[ Fe/H]), microturbulent and rotational velocities and, lithium abundances (ALi) for 27 evolved stars of M 67 with the spectral synthesis method based on MARCS model atmospheres. We also computed non-standard stellar evolution models, taking into account atomic diffusion and rotation-induced transport of angular momentum and chemicals that were compared with this set of homogeneous data. Results. The lithium abundances that we derive for the 27 stars in our sample follow a clear evolutionary pattern ranging from the turn-off to the Red Giant Branch. Our abundance determination confirms the well known decrease of lithium content for evolved stars. For the first time, we provide a consistent interpretation of both the surface rotation velocity and of the lithium abundance patterns observed in an homogeneous sample of TO and evolved stars of M 67. We show that the lithium evolution is determined by the evolution of the angular momentum through rotation-induced mixing in low-mass stars, in particular for those with initial masses
Agreeableness and interpersonal forgiveness in young adults : the moderating role of gender

interest in psychological correlates and personality substrates of forgiveness has been growing recently. empirical evidences have suggested that agreeableness may be the most robust predictor of forgiveness and revenge. this article examined gender differences in the relationship between this dispositional quality and interpersonal forgiveness in a sample of young adults. this study also tested the role of gender as a potential moderating factor between dispositional traits and forgiveness dimensions. While no gender differences were found in agreeableness in our sample, females scored lower in motivation to avoid while males scored higher in motivation to revenge. Results also indicated that agreeableness was significantly associated with motivations to avoid (only in males) and seek revenge (for both genders). Finally, gender also moderated the association between agreeableness and motivation to revenge. Our findings are discussed in terms of the need for future research to consider these differences in further positive psychology intervention programs.
The Impact of TTIP: The Underlying Economic Model and Comparisons

What are the economic and other impacts of the Transatlantic Trade and Investment Partnership? At the request of the European Parliament, CEPS has provided an appraisal of the TTIP Impact Assessment carried out by the European Commission, with special elaboration of the underlying economic model. The methodology applied by the Centre for Economic Policy Research (CEPR) for this economic modelling is analysed in depth, together with the assumptions used to make TTIP amenable to an economic appraisal. The research paper also compares the IA on TTIP with selected previous empirical economic assessments of EU trade agreements and with a set of alternative studies on TTIP itself. In reading our findings, two central caveats should be kept in mind that affect any analysis of the CGE model included in the European Commission’s Impact Assessment. First, TTIP is a rather unusual bilateral trade agreement; and second, TTIP is so wide-ranging that an alternative approach, such as the so-called ‘partial’ (equilibrium) approach – already a second-best solution – would be totally inappropriate to the case under examination.
Urine patch area coverage of an intensively stocked dairy pasture

The urine patch of the grazing cow has been identified as the key source of N loss from pasture-based dairy systems. Although critical to N modelling, quantitative data on the annual area coverage of urine patches in pastures is scarce. A new technique using survey-grade global positioning system (GPS) technology was developed to measure the paddock area coverage of dairy cattle urine and dung patches. A four year study was conducted on an intensively stocked (4.3 cows/ha) dairy farm in Canterbury, New Zealand. Twelve field plots on typical grazed pasture were monitored over a four year period, sampling at 12 week intervals. Urine and dung deposits within the plots were visually identified, the pasture response area (radius) measured and position marked with survey-grade GPS. Spatial geographic information system (GIS) software was used to analyse the data. The mean urine patch pasture response area was 0.35 m 2 . It was calculated that the mean area covered by urine patches on an annual basis was 23.1 ± 2.2 % for the given stocking density and grazing management regime.
Effects of osmotic dehydration factors on convective drying kinetics of pears slices (Pyrus Communis L.)

The paper presents results of the research on the effects of osmotic dehydration, applied as a pre-treatment, on convective drying kinetics of pear cultivars 'William', in the form of ¼ of fruit, i.e. slices. Three-factor experiment of convective drying of pear slices was performed, while the experiment factors were pre-treatment, drying air temperature and velocity of drying air in front of the layer of materials. The following pre-treatment forms were applied: osmotic drying with solution temperature 40oC and solution concentration 50Bx, osmotic drying with temperature 60oC and solution concentration 65 Bx, and pear slices placed in a convective dryer with no pre-treatment. The statistical method of dispersion analysis in the three-factor experiment was used to evaluate the effects of the analyzed factors on the kinetics of convective drying of slices. On the basis of the analysis it was determined that the selected pre-treatments and drying air temperature are important for kinetics of convective drying, while air velocity in front of the layer of material is less important, as well as the mutual interaction of the factors.
Code camp: a setting for collaborative learning of programming

Collaborative learning is studied, especially in the light of the code camp approach, in this paper. Code camp means a short, intensive collaborative learning event in which participants work in groups. Two code camp settings and one traditional programming course are presented. Students of the courses completed questionnaires, and the answers were analyzed to establish the value of the code camp approach. It seems that students like the code camp approach, and the results seem to be better than with traditional approaches to learning of programming.
Biological Control of Cactaceae in South Africa

This review is a summary of developments that have contributed to the success of several biological control programmes against invasive cactus species (Cactaceae) that have been worked on in South Africa over the last 12 years. Six potential biological control agents have been identified for the control of Pereskia aculeata Mil. and molecular studies have identified the origin of the South African P. aculeata population. Host-specificity testing is now required for the three most promising of these agents. The successful biological control programme against Opuntia stricta (Haw.) Haw. has resulted in a change in management strategies against this weed in the Kruger National Park and the control of O. stricta is now almost entirely reliant on biological control. Taxonomic problems associated with the identification of Cylindropuntia fulgida var. fulgida (Engelm.) F.M. Knuth var. fulgida have been resolved and an appropriate cochineal insect (Hemiptera: Dactylopiidae) biotype has been released, resulting in substantial declines in Cyl. fulgida var. fulgida populations. A long-term monitoring programme has been initiated to evaluate the progress of this new cochineal insect biotype. The Harrisia mealybug, Hypogeococcus pungens Granara de Willink (Hemiptera: Pseudococcidae), which was originally released on Harrisia martinii (Labour.) Britton & Rose has been collected and redistributed onto Cereus jamacaru DC. , where it reduces fruit production and leads to the death of both seedlings and large plants. Resolving taxonomic problems to ensure the correct identification of plant species and the most appropriate biological control biotypes have been key issues that have led to the successful control of several cactaceous weed species in South Africa.
Conservation and Sustainable Management of Traditional Ecosystems in Garhwal Himalaya, India

Forest and agricultural biodiversity play an important role in sustaining livelihood of local people in marginal land in Central Himalayan village ecosystems. These village communities have their own rules and regulations for conservation and management of agroecosystems as well as surrounding forest ecosystems. To assess the pattern of change in conservation and sustainable management of traditional agroecosystems, a participatory rural appraisal (PRA) was conducted and information collected from farmers. In the Study area traditional food crops and multipurpose agroforestry trees were replaced by cash crops during the recent past, due to the changes in the economic and political issues. These village ecosystems have become either degraded or less fertile ecosystems. The study focuses on the issues of conservation and sustainable development.
