ARAŞTIRMA DEMODEX ( ACARI : DEMODICIDAE ) INFESTATION IN THE ELDERLY AND ITS RELATIONSHIP WITH THE SKIN PARAMETERS SUCH AS MOISTURE , PH , AND TEMPERATURE : A CROSS-SECTIONAL STUDY

Giriş: Tüm dünyada olduğu gibi ülkemizde de her geçen yıl yaşlı nüfusu artmaktadır. Bu nedenle yaşlı bireylerle ilgili yapılacak olan çalışmalar büyük öneme sahiptir. Bu çalışma huzurevinde kalan yaşlılarda Demodex enfestasyonunu belirlemek ve cildin nem, pH ve ısı parametreleriyle olan ilişkisini ortaya koymak amacıyla yapıldı. Gereç ve Yöntem: Çalışmaya Erzincan 100. Yıl Atatürk Huzurevinde kalan 91 yaşlı dahil edildi. Yaşlıların cilt nemi, cilt pH’sı ve cilt ısısı ölçülerek yanak, nazolabiyal ve çene bölgelerinden Standart Yüzeyel Deri Biyopsi (SYDB) yöntemi ile örnekler alındı ve ışık mikroskobunda incelendi. Bulgular: Yaşlılardan %84.6’sında D. folliculorum (mean 29.3/cm2), %45.1’inde D. brevis (mean 4.3/cm2) olmak üzere %85.7’sinde Demodex mites (mean 31.1/cm2) tespit edildi. Enfestasyonun en fazla yanakta olduğu (ortalama 21.2/cm2), bunu sırasıyla nazolabial (ortalama 9.4/cm2) ve çene (ortalama 7.4/cm2) bölgesinin izlediği görüldü. Yüz bölgeleri ile Demodex enfestasyonu arasındaki fark istatistiki bakımdan anlamlı bulundu (p<0.001). Demodex enfestasyonunun cildi kuru olanlarda, cilt pH’sı 5.6-7.0 olanlarda ve cilt ısısı yüksek olanlarda daha fazla olduğu tespit edildi. Demodex enfestasyonu ile cilt nemi arasındaki fark istatistiki olarak anlamlıyken (p=0.035), cilt pH ve ısısı ile arasındaki fark anlamlı değildi. Sonuç: Yaşlılardan cildi kuru, cilt ısısı yüksek ve cilt pH’sı yüksek olanların Demodex akarlarla daha fazla enfeste olduğu görüldü. Bu durumun geriatrik hastalardaki cilt lezyonları ve dermatozların klinik değerlendirmesinde göz önünde bulundurulması faydalı olabilir.

Evolutionary trends in onshore-offshore distribution patterns of mushroom coral species (Scleractinia: Fungiidae)

A phylogenetically based comparative analysis of onshore-offshore distribution patterns of mushroom coral species (Scleractinia: Fungiidae) was made to reconstruct an evolutionary scenario for differentiation in fungiid shelf habitats. This phyloecological study integrates data on fungiid distribution patterns along environmental gradients on the Spermonde Shelf, SW Sulawesi, with a recently published phylogeny reconstruction of the Fungiidae. A mushroom coral fauna of 34 species was used to compare their distributions by use of 50-m2 belt quadrats in transects (1) from the mainland to the shelf edge, (2) around reefs with regard to predominant wind directions, and (3) over bathymetrical reef zones. Species association ordinations were made for each of the four shelf zones using both abundance and incidence data to examine whether closely related species cooccurred. Some closely related species or even sister species appeared to show very similar distribution patterns and to coexist in high abundances. These results indicate that there may not be community saturation and competitive exclusion amongmushroom corals species, most of which are free-living. In reconstructions of fungiid habitat evolution, offshore reef slopes appear to be original (ancestral), whereas onshore habitats, shallow reef flats, and deep sandy reef bases seem to be derived. The latter is in contrast with an earlier hypothesis, in which deep sandy substrates were considered ancestral mushroom coral habitats.
Biological assets reporting: Is the increase in value caused by the biological transformation revenue?

Rural areas represent 91% of the area of 27 European Union (EU) member states and home for more than 56% of their inhabitants as mentioned by the European Commission (2007), which makes the rural development policy very important. Agriculture and forestry have the fundamental importance for the exploitation of farmland and the administration of natural sources in the rural areas of the EU as the platform for the economic diversification of rural areas. Agricultural activity differs from other activities carried out by business units to achieve the profit. Agricultural activity is in comparison with other activities of business subjects dependent on the natural and environmental conditions, and therefore the agriculture specialization is narrowly connected with the geographical position. Another fact, which significantly influences the extent and quality of agricultural production, mainly in the case of plant production, represents the significant dependence on weather conditions and other factors (pests, diseases, etc.), which can be influenced by the action of the human factor only in a restricted extent. As another factor which cannot be influenced, there is considered the biological character of agricultural production – it is necessary to respect the biological characteristics, e.g. the vegetation period, the length of the production cycle, etc., which usually overlap the period of one year. The fact that some products are further consumed by the agricultural enterprise itself could be considered as specific in agricultural production as well. Farm products may be used in the related activities, such as feeding hay and grain to livestock or poultry, or they may be marketed directly by the producer. The narrow connection with farmland which represents a scarce source is considered as a restrictive factor.
Electrochemical and Mechanical Failure of Graphite-Based Anode Materials in Li-Ion Batteries for Electric Vehicles

Graphite-based anode materials undergo electrochemical reactions, coupling with mechanical degradation during battery operation, can affect or deteriorate the performance of Li-ion batteries dramatically, and even lead to the battery failure in electric vehicle. First, a single particle model (SPM) based on kinetics of electrochemical reactions was built in this paper. Then the Li-ion concentration and evolution of diffusion induced stresses (DISs) within the SPM under galvanostatic operating conditions were analyzed by utilizing a mathematical method. Next, evolution of stresses or strains in the SPM, together with mechanical degradation of anode materials, was elaborated in detail. Finally, in order to verify the hypothesis aforementioned surface and morphology of the graphite-based anode dismantled from fresh and degraded cells after galvanostatic charge/discharge cycling were analyzed by X-ray diffraction (XRD), field-emission scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results show that large volume changes of anode materials caused DISs during Li-ion insertion and extraction within the active particles. The continuous accumulations of DISs brought about mechanical failure of the anode eventually.
In vitro and in vivo evaluation of antimicrobial activities of essential oils extracted from some indigenous spices.

Received: Revised: Accepted: July 27, 2012 April 15, 2013 April 28, 2013 The study was conducted to investigate the antimicrobial activity of some indigenous essential oils (EOs) extracted by hydrodistillation from spices such as Cuminum cyminum, Amomum subulatum, Cinnamomum verum and Syzygium aromaticum against Escherichia coli, Salmonella typhi, Staphylococcus aureus, Bacillus subtilis, Aspergillus flavus and Candida albicans by performing the disc diffusion assay and minimum inhibitory concentration (MIC) in-vitro, and in vivo antibacterial effect of EOs was studied in rabbits infected with S. aureus and treatment was done at infected site immediately with EOs. Among all treated groups, C. verum EO treated group showed significant decrease in viable bacterial counts at infected site after 24h and 48h of infection to 7.4×10 and 7.6×10 cfu, respectively, from 4.3×10 cfu before treatment. C. verum EO was found to be the most effective against S. aureus and C. albicans, showing zone of inhibition diameters 34±2.0mm and 50.3±8.6mm, respectively. The EOs, applied at different concentrations, showed variable inhibitory effects to all the microorganisms tested and more effective than control, both in-vitro and in-vivo. The results of the present study screened out the antibacterial and antifungal potential of the EOs, however further dose dependent studies, both in-vitro and in-vivo are required to find out their maximum safe levels against bacteria and fungi. ©2013 PVJ.

Instructional strategies to promote conceptual change about force and motion: A review of the literature

During the last four decades, the results of a great deal of research have indicated that, prior to any formal instruction in physics, students hold scientifically incorrect ideas about physics concepts in general, and about the force and motion concepts in particular, the latter being considered central in science teaching. To these days, students’ conceptual difficulties in mechanics have been well documented and a considerable body of research literature in science education has been formed. In the present study we first review briefly most commonly encountered students’ alternative conceptions and mental barriers in school mechanics. Subsequently, we present teaching approaches that attempt to confront the aforementioned difficulties in students’ thinking. Ultimately, with respect to the studies presented, we attempt to highlight potentially effective characteristics of learning environments and strategies suitable for the promotion of conceptual change in school mechanics.
TRAFFIC FATALITIES AND ALCOHOLIC LIVER DISEASE IN FINLAND - A COMPARATIVE STUDY OF THE YEARS 1982-1985 AND 1989-1990

This paper reports the results of a Finnish study to clarify the correlation between liver disease, associated with alcoholism, and traffic casualties. The study also investigated whether the presence of liver disease in fatal casualties reflected the steady rise of alcohol consumption in Finland during the 1980s, and the simultaneous rise in the proportion of alcohol-associated drivers among fatal casualties. Autopsies were made of all motor vehicle drivers who died in road accidents in Helsinki or in the surrounding province of Uusimaa during 1989-90, together with five additional drivers. This sample of 117 consisted of 107 males and ten females, aged 15 to 78. It was possible to analyse 105 livers, 50 of which were found to be diseased, including 41 cases of steatosis (ten of them severe), seven cases of alcoholic hepatitis, and two cases of cirrhosis. Blood alcohol concentration (BAC) was at least 0.035% in 25 of the cases, where the observed BACs ranged from 0.067% to 0.29%. There was no close correlation between BAC and liver damage. Comparison with an earlier study suggests a rise in moderate and heavy steatosis among traffic casualties, indicating a rise in heavy use of alcohol and alcoholism among drivers killed in traffic accidents.

BAND SURGERY ON KNOTS AND LINKS

We give some relationships of the Jones and Q polynomials between two links which are related by a band surgery. Then we consider two applications: The first one is to an evaluation of the ribbon-fusion number, the least fusion number of a ribbon knot. The second one is to DNA knot theory, helping us to understand the action of the Xer site-specific recombination at psi site.
EXTENT OF ADOPTION OF EDI BY SINGAPOREAN SMES: A SURVEY OF PRACTICES

[Abstract]: Based on the literature review of EDI adoption and small business use of IT, the four variables of decision factor that influence Singaporean SMEs to adopt EDI were identified as perceived benefit of EDI, organizational readiness for EDI,competitive pressure, and power and inter-organization relationships. Furthermore, EDI volume, diversity, depth, and width were also identified as to the degree of EDI adoption/integration that strongly influences the impact of EDI. Finally, the different levels of impact (transaction benefit, information sharing benefit, and competitive benefit) associated with the different degrees of EDI adoption/integration were also identified. This survey-based research examined these three concepts in Singaporean SMEs. Surprisingly, Singaporean SMEs seldom expected that adoption of EDI would improve their trading partner relationships. However, Singaporean SMEs improved their level of awareness of EDI benefits after adoption of EDI.
Separation time analysis of transient magnetohydrodynamic mixed convection flow of nanofluid at lower stagnation point past a sphere

In this paper, the unsteady magnetohydrodynamics (MHD) mixed convection flow of nanofluid at lower stagnation point past a sphere is studied. Nanoparticles Cu and TiO 2 with water as a base fluid are considered. The separation times of the flow as the boundary layer start to separate at the surface of the sphere are given attention. The governing boundary layer equations in the form of partial differential equations are transformed into nonlinear coupled ordinary differential equations and solved numerically using an implicit finite-difference scheme known as Keller-box method. Results of the separation times of boundary layer flow for viscous and nanofluid influenced by magnetic parameter and volume fraction are shown in tabular form and analysed. This study concluded that the separation times can be delayed by added more magnetic particles and small amount the volume fraction.

Scale, Skill, and Team Management: Organizational Structure of Mutual Fund Families

We develop a model of delegated portfolio management with two layers of agency problems, derive implications for single-manager vs. team funds, and test model implications using mutual fund data. A team fund with two managers can always operate as two separately-run funds and report the combined performance. Thus, a team fund should have at least as good a riskadjusted performance as the two sub funds, with weighted average expected returns and lower risk due to diversification. Yet in reality we often observe lower performance for team funds. Our model explains why. Fund families optimally choose risk sharing contracts for their team funds to maximize their own profit. As a result, better skilled managers prefer not to join a team. Fund families design contracts to induce a mix of single-manager and team funds to maximize their own profit, which is different from maximizing fund performance for investors. Moreover, families with more convex compensation (e.g., due to convex fund flows) optimally choose a lower fraction of team-managed funds and have a lower average performance. We find empirical evidence consistent with our model’s predictions regarding team management and fund performance. ∗Huang is from Cheung Kong Graduate School of Business (email: cyhuang@ckgsb.edu.cn), Qiu and Xu are from Renmin University of China (email: zhigang.qiu@ruc.edu.cn and davidxu@ruc.edu.cn), and Tang is from Singapore Management University (email: yhtang@smu.edu.sg).
Training by firms in Italian regional labour markets: the effects of education and unemployment

This paper analyses the determining reasons of the differences among the Italian regions in matter of investment in workers’ training. Training incidence in Italy is not homogeneous among regions, with a lower intensity in the South. Two not alternative explanations are proposed at a theoretical level and tested by econometric estimates, referring to the complementarity between education and training and to the effects of regional unemployment. Both hypotheses, as the results show, are upheld by empirical estimates, based on the European Community Households Panel. In our results educational level appear to be important as it affects the choice made by the firm of which workers to offer an opportunity of training, whereas unemployment rate and wage compression affect the decision of how many workers to train. The unemployment effect found out by this paper confirms that, as it has been pointed out by most recent developments of human capital literature, the firms incentives to pay for general training depend on the level of wage compression. Notwithstanding it represents an original result as compression in this model doesn’t depend on institutional factors, as usually assumed in the literature, but on the dependence of unskilled wage on regional unemployment.
A concept for wildlife tracking using ultra high frequency (UHF) radio

Wildlife tracking technology is a method routinely used in the detection of small animals or big animals. Normally, a radio tracking using a low frequency between 30MHz to 300MHz known as Very High Frequency (VHF). In this study, a band of Ultra High Frequency (UHF) with a frequency 315MHz is used as a transmitter. While a encoder HT12E is used as a function of generate a data signal to the RF Transmitter module 315MHz to transmit. The signal sent by the transmitter detected by Yagi antenna as a receiver and was designed at a frequency of 315MHz with a gain is 10.68dBi. Received power detected by Yagi antenna shown at Anritsu Spectrum Analyzer. The highest differences between power received at vegetation area compared to open area is about 10dBm while the furthest distance of the receiver can be traced in the vegetation area is about 67 meters, and for open area is more than 70 meters. The results of this study agreed with Tamir’model for propagation in forest whereas can be used in a prediction of initial pattern of power received signal which is gradually decrease if a receiver moves away from the transmitter over much larger distances.
Source Characterization of Metals in Rainwater: Case Study of Akure, Ondo State, Nigeria

One source of water is rainwater. It is a pure solvent if not polluted. It has diverse functions in humans, animals and other materials. For rainwater not to be polluted, it means the values of cations, anions and particulate matter should be below water permissible limits. In this paper, we have characterized metals in rainwater harvested in Akure, Ondo State, Nigeria using standard methods of analyses. The physico-chemical parameters and metals were below WHO water guidelines. The variation of the metals was as follows: Ca>K>Na>Mg>Zn>Fe>Cu>Pb>Cr. Cd was absent and the Pb content was low. Principal Component Analysis showed that factors 1, 2 and 3 showed high loadings for Cr and Zn; Pb and Ca; and Cu, Mn and Mg respectively. Sources of these metals were due to anthropogenic activities.
Quantum information metric of conical defect

A concept of measuring the quantum distance between two different quantum states that is called quantum information metric has been presented. The holographic principle (anti–de Sitter/conformal field theory) suggests that the quantum information metric Gλλ between perturbed state and unperturbed state in field theory has a dual description in the classical gravity. In this work we calculate the quantum information metric of a theory that is dual to a conical defect geometry and we show that it is n times the one of its covering space. We also give a holographic check for our result in the gravity side. Meanwhile, it was argued that Gλλ is dual to a codimension-one surface in spacetime and satisfies Gλλ=nd·Vol(Σmax)/Ld. We show that the coefficient nd for conical defect should be rescaled by n2 from the one for anti–de Sitter space. A limit case of conical defect—the massless Banados-Teitelboim-Zannelli (BTZ) black hole—is also considered. We show that the quantum information metric of a massless BTZ black hole disagrees with the one obtained by taking the vanishing temperature limit in BTZ black hole. This provides a new arena in differentiating the different phases between BTZ spacetime and its massless cousin.
When non-financial companies invest in risky financial assets : a dynamic panel analysis of determinants of the financial portfolio risk in Norwegian firms

This thesis examines determinants of the risky financial assets of Norwegian firms in the period of 1999 to 2015. Unlike previous research, and as recently requested in recognized academic papers, our analysis is aimed at a larger data sample that also consist of small and unlisted companies. Firstly, we present a literature review, theoretical predictions, and the applied econometric methodology. Then, empirical findings of pooled and first-difference OLS, fixed effects, and Arellano-Bond estimations are shown. In support of the theoretical prediction that financially constrained firms should invest less in risky financial assets, we find that firms with poor credit ratings have less risky financial asset portfolios. Furthermore, also consistent with this theory, we find that the investments in risky financial assets are increasing in the size of the firm. Moreover, firms paying dividends invest significantly less risky. On a different note, companies with concentrated ownership, and proprietorships, appear to invest riskier, possibly contrary to our theoretical predictions. Finally, in an attempt to measure effects of poor corporate governance, we also explore the effects various auditor remarks have on risky financial assets. One of the coefficients, which we relate to the rationality of firms’ financial asset management, indicate that firms invest in riskier financial assets if tax withholdings have not been deposited in a dedicated account, or have not been fully paid.
Utilization of Crosslinked Starch Nanoparticles as a Carrier forIndomethacin and Acyclovir Drugs

An eco-friendly nanoprecipitation technique was put forward to synthesize native starch nanoparticles loaded with insoluble drugs such as indomethacin (IND) and Acyclovir (ACV). Factors studied to find out the optimum conditions for preparation of different formulations of crosslinked starch nanoparticles (TPP-StNPs) loaded with insoluble drugs. The factors are 20 mg, 50 mg of drug concentration and 0.5, 1 g of sodium tripolyphosphate (STPP) while the concentration of starch and surfactant were kept constant. World-class facilities as particle size analyzer, poly dispersity index (PDI), zeta potential, TEM, XRD, FT-IR, UV-vis spectroscopy and DSc were used for evaluation of the resultant crosslinked starch nanoparticles loaded with drug. The sustained release of drugs were evaluated using entrapment efficiency and in vitro release. The data obtained confirmed that there is no chemical interaction between drug (IND, ACV) and crosslinked starch nanoparticles. The results indicate that the best formula for IND loaded starch nanoparticles was 0.5 g STPP and 20 mg IND while the best formula for ACV nanoparticles was at 0.5 g STPP and 50 mg ACV drug.
