Antioxidant and antibacterial activities of essential oil of Lippia sidoides against drug-resistant Staphylococcus aureus from food

Chemical composition, in vitro antioxidant and antibacterial activities of essential oil of Lippia sidoides (EOLS) and its major constituent was investigated. Chemical composition was analyzed in a gas chromatograph coupled to a mass spectrometer (GC/MS). Antioxidant activity (AA) was obtained using 2,2-diphenylpicrylhydrazyl (DPPH) radical scavenging assay. Antimicrobial activity was tested using disk-diffusion test against Staphylococcus aureus ATCC 25923 and nine S. aureus strains resistant to beta-lactams, tetracycline and quinolone. EOLS chemical composition revealed the presence of 15 components identified as monoterpenes hydrocarbon (1.56%), oxygenated monoterpenes (94.31%) and sesquiterpenes hydrocarbon (4.11%), and the major components were thymol (79.70%). All OELS concentrations analyzed showed AA varying from 19.09 ± 2.088% (100 µg/mL) to 74.32 ± 1.61% (3.200 µg/mL). For thymol, the most efficient AA (70.11 ± 3.43%) was found with higher concentration (6.400 µg/mL). All S. aureus strains (n = 10) were sensitive to OELS and thymol. When OELS was used, the halo size of the ATCC strain was 74.4 mm and for the resistant-strains, it ranged from 29 to 60.4 mm. Thymol bioactive was lower when compared with OELS: the ATCC strain showed a halo of 24.5 mm and a variation of 17.5 to 45 mm was observed between the halo sizes in resistant strains. The results suggest that OELS as compared to thymol has better potential for use as an antimicrobial and antioxidant agent.

The Agency Model and Corporate Governance in China: In the Context of Privately-owned Enterprises Transformed to Public Corporations

In the context of transition, where the Chinese enterprises are seeking good models for the corporate governance, one Anglo-American corporate governance model, the agency model, seems to shed some light on enterprises that used to be privately-owned and have transformed into public corporations. Although the agency model might be a solution to the public corporations, it never the less fails to match the Chinese context in many respects. In light of the nature of the agency model and potential mismatches with the Chinese context, this thesis examines theoretical reasons that could account for the discrepancies between the two. It is argued that, despite the foreign nature of this model and the need for amendment, the Chinese public corporations are still be able to establish good corporate governance structure via it.
A LONGITUDINAL STUDY ON THE IMPACT OF CROSS-BORDER VENTURE CAPITAL ON PORTFOLIO COMPANY GROWTH

We study the effects of obtaining initial finance from cross-border venture capital investors—as opposed to only domestic venture capital investors—on the growth pattern of venture capital backed companies. Using a ten-wave longitudinal research design and a random coefficient modeling approach, we track sales, employment and total assets within 766 European high-tech companies that initiate investment relationships with venture capital firms. Findings indicate that companies backed by cross-border investors are larger in terms of sales, employment and total assets at the time of the initial investment. Companies backed by domestic investors have higher instantaneous growth rates when studying growth in sales and total assets, but these growth rates diminish more quickly over time compared to the growth rates of companies backed by crossborder investors.

Wind and Current Effects on Extreme Wave Formation and Breaking

AbstractWind and current effects on the evolution of a two-dimensional dispersive focusing wave group are investigated using a two-phase flow model. A Navier–Stokes solver is combined with the Smagorinsky subgrid-scale stress model and volume of fluid (VOF) air–water interface capturing scheme. Model predictions compare well with the experimental data with and without wind. It was found that the following and opposing winds shift the focus point downstream and upstream, respectively. The shift of focus point is mainly due to the action of wind-driven current instead of direct wind forcing. Under strong following/opposing wind forcing, there appears a slight increase/decrease of the extreme wave height at the focus point and an asymmetric/symmetric behavior in the wave focusing and defocusing processes. Under a weak following wind, however, the extreme wave height decreases with increasing wind speed because of the dominant effect of the wind-driven current over direct wind forcing.

Supplier BIM competence assessments within the cloud: a proposed Fuzzy-TOPSIS approach

Building information modelling (BIM) is regarded as a technological solution for construction supply chain (SC) integration through centralised digital communications. A number of approaches have been proposed for the evaluation of a firm’s capability to deliver BIM. However, none of the existing approaches have been specifically tailored for supplier selection processes. Most of the existing tools have been developed for individual firm capability or maturity evaluations rather than cross comparative assessments for the purpose of selection. Consequently, there remains a lack of tools for prioritising suppliers based on their ability to deliver BIM during evaluations for selection. A Fuzzy-TOPSIS computational framework for implementing such cross comparative assessments is proposed. This method is proposed in view of its suitability for implementation within a cloud-based decision support environment. A high-level architecture for a cloud-based decision support tool (DST) which can incorporate the proposed computational model is presented. The proposed framework is capable of enhancing decision making during the selection process through a robust approach to the aggregation and comparison of SC firm’s BIM competence and readiness.
LOW POWER TERNARY SHIFT REGISTER USING CNTFETS

In the last few decades, interest in multivalued logic has grown rapidly due to its potential advantages over binary logic for designing energy efficient digital systems. In this paper, a ternary D flip flop with preset and clear inputs is designed using Carbon Nanotube Field Effect Transistor based ternary logic gates. The chiralities of the carbon nanotubes (CNT) used for constructing CNTFET based ternary logic circuits are (19, 0), (13, 0) and (10, 0) of diameters 1.487nm, 0.783nm and 1.018nm with threshold voltages of 0.293V, 0.428V and 0.557V respectively. The designed ternary D flip flop is used as basic building gate for constructing serial in and serial out (SISO) shift registers with improved design and energy efficiency. Finally simulation results using Hspice simulator are reported to show that the proposed CNTFET ternary logic circuits consume significantly less power with considerable reductions in power delay product as compared to conventional binary logic circuits.
CARCASS STUDIES IN NA TIVE DUCKS REARED UNDER DIFFERENT HOUSING SYSTEMS

With the aim to examine the effect of rearing systems on major meat quality traits in native ducks, appropriate experimental investigation was conducted. Research material included a total of 160 day-old native ducklings. The experiment was organized in two treatments with two replications each. Two different rearing systems were employed the intensive (cages) and extensive system (free-range). The native ducklings belonging to same hatch were procured from a local duck farmer and reared simultaneously for a period of ten weeks. Twelve ducks (six male and six female) from each treatment were chosen randomly and slaughtered at the end of rearing period to study meat quality traits in native ducks. Differences were significant (P<0.05) among sexes and rearing systems on pre slaughter live weight, eviscerated weight and various cut up parts, the corresponding values are higher for intensively reared ducks. Regarding sex, both male and female ducks exhibited differences considerably higher weight gain, carcass and cut up parts yield than that of female ducks.
The Linewidth Broadening Factor: A Length-Scale-Dependent Analytical Approach

A first-order frequency-dependent formula of the linewidth broadening factor (α–factor) is derived in terms of scattering rates whilst, a mesoscopic disk approach is used in order to accompany the dimension effect to the spontaneous emission lifetime (inverse of scattering rate). An excitonic correction to the relaxation properties is shown to occur provided the binding energy of the electron and hole is comparable to their eigenenergy-separation. The ensuing analysis is independent of the selected III-V material system and resides upon three simplifying assumptions which allow for analytical formulae to be derived.
DESIGNING COLLABORATIONS AT THE INTERSECTION OF ACADEMIA AND INDUSTRY

Since the Bauhaus, industry and product design education have been intrinsically linked. A century later, industry collaborations still form a major component in product design education. In 2016, the opportunity arose for around 50 undergraduate students studying both Product and Digital Interaction Design (BSc) at the University of Dundee to take part in the 2016 Microsoft Research Design Expo. This global student competition challenged the students to explore ‘Symbiosis and the Conversational User Interface (CUI)’. Over the course of an 11-week semester, the students were divided into nine inter-disciplinary teams with one team later selected to disseminate their project at the annual Microsoft Faculty Summit conference in Seattle, USA. Through semi-structured interviews and focus groups with a sample of students, tutors and industry advisors, data was gathered to determine the influence of this collaboration on the total learning experience of all participants. In this paper, we briefly describe the background and context of the project before presenting a sample of student work. The paper then goes on to consider; the tension between competition and collaboration both within a team setting and the wider studio dynamic; how students interpret and incorporate input from both academic tutors and industry advisors; and the role prototypes play in the communication of ideas and concepts during the early stages of the design process. Reflecting on the major relationships and behaviours that all participants need to display, the paper concludes with a series of recommendations that we believe are essential for the design and delivery of future collaborative projects between industry and academia.
Prevalence of undernutrition and its determinants among preschool children in a rural community of Shimoga, Karnataka

Background: Undernutrition is a major health and nutrition problem in India especially among preschool children. It is an important cause of childhood mortality and morbidity and also leads to permanent impairment of physical and mental growth of those who survive. The objective of the study was to estimate the prevalence of undernutrition among preschool children in the study setting and to determine various factors associated with undernutrition of the child.Methods: A cross sectional study was conducted among 400 preschool children in the field practice area of PHC Aaynoor, Shivamogga, Karnataka. Cluster sampling technique was used for sample selection. Data was collected by interviewing the parent /guardian using a pretested and semistructured questionnaire and anthropometric measurements were done as per standard techniques. Statistical analysis was done using WHO Epi-info software version 3.5. 4.Results: The prevalence of underweight, stunting and wasting was observed in 38%, 43% and 15.8% of children respectively. The study found significant association between the prevalence of undernutrition and gender, birth weight, birth order, number of siblings, caste, paternal literacy and availability of toilet in the house of the child.Conclusions: The present study revealed that the problem of undernutrition is critical in the study area and identifies multiple risk factors for its causation, thereby signifying a well - coordinated multi sectorial approach to curb the same.
POPULATION STRUCTURE AND GENE FLOW IN THE CHIPPING SPARROW AND A HYPOTHESIS FOR EVOLUTION IN THE GENUS SPIZELLA

AssTnAcr. -We studied restriction site variation in the mitochondrial DNA (mtDNA) of 55 Chipping Sparrows (Spizella passerina) taken from widely dispersed points in their breeding range. A total of 2 1 haplotypes was observed, and on average, individuals differed little in percent haplotype divergence (0.12%). There was no detectable geographic variation in haplotypes, despite the sampling of three named subspecies. Single-generation dispersal distance was estimated from the mtDNA data at 5.4 km. One phylogenetic hypothesis for six species in the genus (excluding Timberline Sparrow [S. taverneri] and Worthen’s Sparrow [S. worthenl]) suggested that Black-chinned Sparrow (S. atroguluris) and Field Sparrow (S. pusilla) were sister taxa, followed in sequence by Chipping, Brewer’s and Clay-colored sparrows (S. pallida), with the American Tree Sparrow (S. arboreu) most distant. Another hypothesis grouped Chipping and Brewer’s sparrows. Received 24 Aug. 1992, accepted 3 Feb. 1993. An important step in the evolutionary process is the origin of geographic patterns of genetic variation. Patterns of genetic variation form the basis for inferences about evolutionary processes that lead to the origin and maintenance of geographic variation and speciation. In the last 20 years, a number of molecular techniques, including protein electrophoresis and restriction site analysis of mitochondrial DNA (mtDNA; Avise et al. 1987), have been used to describe genetic variation within and among avian populations. For north temperate birds, protein electrophoresis revealed few alleles
Ex vivo assays to predict enhanced chemosensitization by hyperthermia in urothelial cancer of the bladder

Introduction Bladder cancer (urothelial carcinoma) is a common malignancy characterized by high recurrence rates and intense clinical follow-up, indicating the necessity for more effective therapies. Current treatment regimens include intra-vesical administration of mitomycin C (MMC) for non-muscle invasive disease and systemic cisplatin for muscle-invasive or metastatic disease. Hyperthermia, heating a tumor to 40–44°C, enhances the efficacy of these chemotherapeutics by various modes of action, one of which is inhibition of DNA repair via homologous recombination. Here, we explore whether ex vivo assays on freshly obtained bladder tumors can be applied to predict the response towards hyperthermia. Material and methods The cytochrome C release assay (apoptosis) and the RAD51 focus formation assay (DNA repair) were first established in the bladder cancer cell lines RT112 and T24 as measurements for hyperthermia efficiency, and subsequently tested in freshly obtained bladder tumors (n = 59). Results Hyperthermia significantly increased the fraction of apoptotic cells after cisplatin or MMC treatment in both RT112 and T24 cells and in most of the bladder tumors (8/10). The RAD51 focus formation assay detected both morphological and numerical changes of RAD51 foci upon hyperthermia in the RT112 and T24 cell lines. In 64% of 37 analyzed primary bladder tumor samples, hyperthermia induced similar morphological changes in RAD51 foci. Conclusion The cytochrome C assay and the RAD51 focus formation assay are both feasible on freshly obtained bladder tumors, and could serve to predict the efficacy of hyperthermia together with cytotoxic agents, such as MMC or cisplatin.
Autority aware expert search: Algorithm and system for NSFC

This paper describes the peer reviewer finding algorithm used in an aided system to assist the proposal reviewing task in the National Science Foundation of China (NSFC)[1]. We propose a new probabilistic language model in which expert authority is taken into consideration, by introducing a prior probability of candidate into the model. Application codes representing research areas are defined by NSFC and are available for both experts and proposals. We integrate code information into our model as we add a code probability term into the model, thus promote rankings of experts with matched code. All proposals submitted to NSFC are written in Chinese, and since Chinese word segmentation is non-trivial task whose accuracy affects the final results heavily, we try to improve segment accuracy by adding domain-specific terms to a user-editable dictionary. Terminologies are extracted from certain field of bibliography data in NSFC system. Experiments show that our algorithm is effective in real world system like NSFC.
Landfast sea ice stability – mapping pan-Arctic ice regimes with
implications for ice use, subsea permafrost and marine habitats

Abstract. Arctic landfast sea ice has undergone substantial changes in recent decades affecting ice stability with potential impacts on ice travel by coastal populations and industry ice roads. The role of landfast ice as an important habitat has also evolved. We present a novel approach to evaluate sea ice stability on a pan-Arctic scale using Synthetic Aperture Radar Interferometry (InSAR). Using Sentinel-1 images from spring 2017, the approach discriminates between bottomfast, with critical relevance for subsea permafrost, as well as stabilized and non-stabilized floating landfast ice over the main marginal seas of the Arctic Ocean (Beaufort, Chukchi, East Siberian, Laptev and Kara Seas). The analysis draws on evaluation of small-scale lateral motion derived from relative changes in interferometric fringe patterns. This first comprehensive assessment of Arctic bottomfast sea ice extent revealed that by area most of the bottomfast sea ice is situated around river mouths and coastal shallows in the Laptev and East Siberian Seas, covering roughly 4.1 and 5.5 thousand km2 respectively. The fraction between non-stabilized and stabilized ice is lowest in the Beaufort at almost unity, and highest in the adjacent Chukchi Sea. Beyond the simple delineation of landfast ice zones, this work provides a new understanding of how stability regimes may vary between regions and over time. InSAR-derived stability data may serve as a strategic planning and tactical decision-support tool for different uses of coastal ice. Such information may also inform assessments of important sea ice habitats. In a case study, we examined an ice arch situated in Nares Strait demonstrating that interferograms may reveal early-warning signals for the break-up of stationary sea ice.

Effects of physical exercise in winter training conditions on the thermographic temperature distribution of the horse rider's skin.

PURPOSE The purpose of this work was to assess the impact of a specific equestrian training, conducted in winter weather conditions, on the thermovision temperature distribution of a rider's body surface. The study included a riding pair with 12 years of experience (female rider, aged 25, sports active and 16-year-old horse, Trakehner breed). METHODS The study included the temperature distribution of selected parts of the rider's body (the area of the right and left shoulder blade, chest and lumbar section, and the region of the left and right cross) was carried out before and after recreational, jumping and dressage training. Each winter training has been repeated, at dif- ferent times, 10 times, giving a total of 30 workouts. The thermovision measurements were made in a separate room, always under the same conditions. RESULTS Research has shown that, along with the increase in the level and intensity of the training, the body surface temperature of the rider increased. After recreational driving, this temperature increased, compared to the pre-workout measurement, by 3.15°C, after jumping through obstacles to 4.39°C, and in dressage to 5.82°C. CONCLUSIONS The highest increase in body surface temperature (on the example of dressage training) was recorded in the thoracic and lumbar part of the spine region, then in the area of the left and right scapula, while the smallest in the left and right sacral region of the rider.
Poleward Stationary Eddy Heat Transport by the Tibetan Plateau and Equatorward Shift of Westerlies during Northern Winter

The orographic effect of the Tibetan Plateau on atmospheric poleward heat transport is investigated using an atmospheric general circulation model. The linear interference between the Tibetan Plateau‐induced winds and the eddy temperature field associated with the land‐sea thermal contrast is a key factor for enhancing the poleward stationary eddy heat transport. Specifically, Tibetan Plateau‐induced stationary waves producenortherliesoverthecoldeasternEurasiancontinent,leadingtoapolewardheattransport.Inanother hot spot of stationary eddy heat transport over the eastern North Pacific, Tibetan Plateau‐induced stationary waves transport relatively warm marine air northward. In an experiment where the Tibetan Plateau is removed, the poleward heat transport is mostly accomplished by transient eddies, similar to the Southern Hemisphere. In the presence of the Tibetan Plateau, the enhanced stationary eddy heat transport is offset by a comparable reduction in transient eddy heat transport. This compensation between stationary and transient eddy heat transport is seen in observed interannual variability. Both the model and observations indicate that an enhanced poleward heat transport by stationary waves weakens transienteddiesbydecreasingthemeridionaltemperaturegradientandtheassociatedwesterliesinmidlatitudes.
Effect of different sources and levels of some dietary biological additives on: III- body composition and muscular histometric characteristics of Nile Tilapia, Oreochromis niloticus

This study aimed to investigate the effect of dietary graded levels of Aqua Superzyme, Garlen Allicin, and Diamond V (Original XPC) on the chemical composition and histometric parameters of males Nile tilapia Oreochromis niloticus. The carcass composition concerning their DM, CP, and EE contents are increased by age advance, but the ash percentages decreased. At the end of the experiment (16 weeks), DM did not significantly (P≥0.05) influence by all dietary treatments; yet, 0.01% of the diet of either the 1 st two substances was responsible for the highest CP and ash percentages and the lowest EE and energy contents. Moreover, 0.5% of the diet of the 3 rd substance gave the highest (P≤0.05) level among its tested levels concerning CP and the lowest (P ≤0.05) EE and energy contents, but ash was not affected (P≥0.05). The best treatment (highest carcass crude protein and lowest ether extract percentages) was feeding fish the diet containing Diamond V-Original XPC at 0.5% of the diet. The same probiotic at the same level led also to improve most of the histometric characteristics of the dorsal muscles. So, it could recommend the dietary inclusion of the probiotic Diamond V-Original XPC at 0.5% of the tilapia diet.
