Oxymoronim as a Semantic Unity of Contrasts
Authors: Коробкина  , Korobkina N. 
Published: June 2016

An oxymoronimis is considered as a reflection of linguistic duality and a
result of conceptual integration. An oxymoronimas as a result of a modern
word creation and an oxymoron as a well-known stylistic device are
compared structurally and semantically. The key semantic sign of an oxymoronim
(a unity of contrasts) is singled out. In addition to that a possible
definition of this notion is stated.On the one hand a cognitive dissonance
of an oxymoron is underlined, on the other hand an attention is paid on the
instability, diffusion and emergence of an oxymoronim’s semantics. It is obviously
possible to interpret a lexical meaning of an oxymoronim by means
of the following: extralinguistic and linguistic contexts of its appearance and
functioning and this nomination’ssynonymic paroemias. Uniqueness of an
occasional oxymoronimis is noted for the Russian lingvoculture in view of
quantitative leveling of these linguistic novelties in the communicative space
of the modern English language.

Pharmacokinetic comparisons of S-oxiracetam and R-oxiracetam in beagle dogs
Authors: Wang Wusan , Ji Hui , Li Tingting , Jia Yuanwei , Xie Haitang 
Published: June 2016

Abstract
A pharmacokinetic comparison and conformational stability study of S-oxiracetam (S-ORT) and R-oxiracetam (R-ORT) in beagle dogs was used to investigate the possible mechanism of different effects of two oxiracetam enantiomers through a random crossover design. After drug administration to beagle dogs, blood samples were collected at different time points for pharmacokinetic analysis using the UPLC-ESI-MS/MS method. Parts of plasma samples were used for conformation transformation studies using a normal phase high performance liquid chromatographic (NP HPLC) method. The study showed that oxiracetam enantiomers maintained their original conformation when administered orally to beagle dogs. Concentrations of S-ORT were significantly higher than R-ORT 1.5 and 2 h after administration; the AUC
0-∞ of S-ORT after oral administration tended to be higher than that of R-ORT, which showed that the different effects between S-ORT and R-ORT may be partly associated with their distinctive absorption at least.

Published: June 2016

Abstract

Centella asiatica was extracted by methanol. The assay content of triterpenes in the extract was 0.12 % asiatic acid, 0.54 % madecassic acid, 0.25 % asiaticoside and 1.02 % madecassoside. The extract was complexed with hydroxypropyl-β-cyclodextrin (HP-β-CD) and formulated with Eudragit E100, glycerol, PEG 400, copovidone, ethanol and purified water. A clear yellowish solution (F1-F8) was obtained. The formulations had a pH of 5.5–6.0 with viscosity in the range of 20–60 mPa s, surface tension 20.3–24.6 mN m–1 and contact angle less than 20°. The amount of PEG 400 and copovidone affected the film and spreadability. The content of triterpenes in the spray formulation was close to 100 % compared to triterpenes in the extract. The skin irritation study indicated that the formulation was non-irritating in a rat model. An in vivo excision wound healing model showed that wound excision was completely healed after 14 days.

Diastatic entropy and rigidity of complex
hyperbolic manifolds
Authors: Mossa Roberto 
Published: June 2016

Abstract
Let f : Y → X be a continuous map between a compact real analytic Kähler manifold (Y, g) and a
compact complex hyperbolic manifold (X, g0). In this paper we give a lower bound of the diastatic entropy
of (Y, g) in terms of the diastatic entropy of (X, g0) and the degree of f . When the lower bound is attained
we get geometric rigidity theorems for the diastatic entropy analogous to the ones obtained by G. Besson, G.
Courtois and S. Gallot [2] for the volume entropy. As a corollary,when X = Y,we get that the minimal diastatic
entropy is achieved if and only if g is isometric to the hyperbolic metric g0.
Assessing of landscape potential for water management regarding its surface water (using the example of the micro-region Minčol)
Authors: Kunáková Lucia 
Published: June 2016

Abstract
The presence of water is one of the decisive factors of landscape’s natural potential. Water affects landscape’s predisposition for agricultural production, water supply available to the wide population and industry (the most important is the yield of water resources). Ponds, lakes and other water areas are zones of recreation and relaxation. Near sources mineral water, several world-famous spas were build. Waterways are also used to generate electricity. Geothermal underground water represents a very significant landscape potential. Determining hydrological potential of the area is important for the regional development. This paper assesses the landscape potential for water management regarding its surface waters in the micro-region Minčol. The micro-region was divided by a square grid, and for each square, we determined the appropriateness of this potential based on score points. The determining evaluation criteria were static reserves of surface water, waterway ranking and annual average discharge. First, we determined the significance (value) of individual criteria (classification characteristics), and then we calculated the values of individual classifiers, which were then multiplied by the value of the individual classifier intervals. The summary of points in each square belongs to a particular degree of suitability for water management based on surface waters. The potential was divided into five degrees (intervals): very unfavourable potential, unfavourable potential, moderately favourable potential, favourable potential and very favourable potential.
Epigenetic regulation of KLK7 gene expression in pancreatic and cervical cancer cells
Authors: Raju Ilangovan , Kaushal Gur P. , Haun Randy S. 
Published: June 2016

Abstract
Kallikrein-related peptidase 7 (KLK7) is a serine protease encoded within the kallikrein gene cluster located on human chromosome region 19q13.3-13.4. KLK7 is overexpressed in human pancreatic ductal adenocarcinomas (PDACs), but not in normal pancreas. Examination of KLK7 mRNA levels in pancreatic cancer cell lines revealed that it is readily detected in MIA PaCa-2 and PK-1 cells, but not in Panc-1 cells. Treatment of Panc-1 cells with the histone deacetylase (HDAC) inhibitor trichostatin A (TSA) significantly induced KLK7 mRNA expression. Similarly, KLK7 is highly expressed in cervical cancer cells, but its expression in the human cervical cancer cell line HeLa is only detected following TSA treatment. Promoter deletion analysis revealed that the proximal -238 promoter region, containing a putative Sp1-binding site, was sufficient for TSA activation of luciferase reporter activity, which was abrogated by the disruption of the Sp1-binding sequence. Consistent with the notion that TSA induced KLK7 expression via Sp1, co-expression of Sp1 with the KLK7-promoter/luciferase construct produced a significant increase in reporter activity. Chromatin immunoprecipitation (ChIP) analysis revealed enriched Sp1 occupancy on the KLK7 promoter following TSA treatment. Similarly, ChIP analysis showed the histone active mark, H3K4Me3, in the KLK7 promoter region was significantly increased after exposure to TSA.

Evaluation of FSO Link Using Array of Photodetectors
Authors: Singh Mehtab 
Published: June 2016

AbstractIn recent years, free-space optics (FSO) communication links have gained importance due to the availability of high data transmission rates and channel bandwidth. Although FSO links have many advantages, it also suffers from many limitations, which degrade the performance of the communication link. In this paper, the performance of an FSO link has been evaluated under fog weather condition as it severely degrades the quality of the received signal. One of the most important techniques to improve the quality of received signal in an FSO link is by using an array of photodetectors at the receiver end. In this paper, the performance evaluation of an FSO link has been performed using an array of photodetectors at the receiver end using OPTISYSTEM simulation software. The performance has been analyzed by evaluating
Numerical Analysis of the Performance of Millimeter-Wave RoF-Based Cellular Backhaul Links
Authors: Pham Thu A. , Pham Hien T. T. , Le Hai-Chau , Dang Ngoc T. 
Published: June 2016

AbstractIn this paper, we study the performance of a next-generation cellular backhaul network that is based on a hybrid architecture using radio-over-fiber (RoF) and millimeter-wave (MMW) techniques. We develop a mathematic model and comprehensively analyze the performance of a MMW/RoF-based backhaul downlink under the impacts of various physical layer impairments originated from both optical fiber and wireless links. More specifically, the effects of nonlinear distortion, chromatic dispersion, fading, and many types of noises including shot noise, thermal noise, amplifier noise, and relative intensity noise are investigated. The numerical results show that the nonlinear distortion, fiber dispersion, and wireless fading are key factors that limit the system performance. Setting the modulation index properly helps minimize the effect of nonlinear distortion while implementing dispersion shifted optical fibers could be used to reduce the impact of dispersion and as a result, they can improve the bit-error rate. Moreover, it is also verified that, to mitigate the effect of multipath fading, remote radio heads should be located as near the remote antenna units as possible.
On a Modular Approach to the Design of Integrated Social Surveys
Authors: Ioannidis Evangelos , Merkouris Takis , Zhang Li-Chun , Karlberg Martin , Petrakos Michalis , Reis Fernando , Stavropoulos Photis 
Published: June 2016

Abstract
This article considers a modular approach to the design of integrated social surveys. The approach consists of grouping variables into ‘modules’, each of which is then allocated to one or more ‘instruments’. Each instrument is then administered to a random sample of population units, and each sample unit responds to all modules of the instrument. This approach offers a way of designing a system of integrated social surveys that balances the need to limit the cost and the need to obtain sufficient information. The allocation of the modules to instruments draws on the methodology of split questionnaire designs. The composition of the instruments, that is, how the modules are allocated to instruments, and the corresponding sample sizes are obtained as a solution to an optimisation problem. This optimisation involves minimisation of respondent burden and data collection cost, while respecting certain design constraints usually encountered in practice. These constraints may include, for example, the level of precision required and dependencies between the variables. We propose using a random search algorithm to find approximate optimal solutions to this problem. The algorithm is proved to fulfil conditions that ensure convergence to the global optimum and can also produce an efficient design for a split questionnaire.
The Impact of Question Format, Context, and Content on Survey Answers in Early and Late Adolescence
Authors: Diersch Nadine , Walther Eva 
Published: June 2016

Abstract
Self-reports in surveys are often influenced by the presented question format and question context. Much less is known about how these effects influence the answers of younger survey respondents. The present study investigated how variations in response format, answer scale frequency, and question order influence self-reports of two age groups: younger (11–13 years old) and older (16–18 years old) adolescents. In addition, the impact of the respondents’ level of familiarity with the question content was taken into account. Results indicated that younger adolescents are more strongly influenced by the presented question format and context than older adolescents. This, however, was dependent on the particular question content, implying that response effects are more pronounced when questions deal with issues that lie outside of the respondents’ field of experience. Implications of these findings in survey research with younger respondents are discussed.
Misspecification Effects in the Analysis of Panel Data
Authors: Vieira Marcel de Toledo , Smith Peter W.F. , Salgueiro Maria de Fátima 
Published: June 2016

Abstract
Misspecification effects (meffs) measure the effect on the sampling variance of an estimator of incorrect specification of both the sampling scheme and the model considered. We assess the effect of various features of complex sampling schemes on the inferences drawn from models for panel data using meffs. Many longitudinal social survey designs employ multistage sampling, leading to some clustering, which tends to lead to meffs greater than unity. An empirical study using data from the British Household Panel Survey is conducted, and a simulation study is performed. Our results suggest that clustering impacts are stronger for longitudinal studies than for cross-sectional studies, and that meffs for the regression coefficients increase with the number of waves analysed. Hence, estimated standard errors in the analysis of panel data can be misleading if any clustering is ignored.

Abstract

Introduction: The aim of this study was to investigate fluorescein use in the diagnosis of bladder ruptures in rabbits as an experimental model.

Material and Methods: The study was conducted on male New Zealand rabbits divided into a retrograde fluorescein group (n = 8) and an intravenous (IV) fluorescein group (n = 8). Following general anaesthesia, 10 mL of 10% fluorescein dye (sodium fluoresceine powder) was administered via ureterorenoscope to the bladder of the first group, and 0.5 mL of 10% fluorescein was administered intravenously to the second group. Then, the bladder was viewed through the cystoscope by urethral aspect. After experimental bladder perforation, groups were comparatively evaluated by paracentesis and laparotomy.

Results: Following IV injection of fluorescein dye, the bladder veins were stained green within 10 s and then fluorescein mixed with urine flowed into bladder lumen. The green fluid flow was observed in the abdominal cavity after the perforation of the bladder in both groups.

Conclusion: Fluorescein can be used as a marker in diagnosis of bladder ruptures. If there is no bleeding or intestinal content in the abdominal cavity, although a smoky yellow-green image is observed, bladder rupture can be suspected.
Macroscopic and microscopic study of integuments on ostrich (Struthio camelus) foot
Authors: Zhang Rui , Ma Songsong , Li Xiujuan , Luo Gang , Xue Shuliang , Li Jianqiao 
Published: June 2016

Abstract

Introduction: Ostrich characteristics include fast running, of which the probable enablers have been studied. Yet little research has taken place on one anatomical feature. It is mainly the special integuments on the ostrich foot which facilitate fast running on sand, because as point of direct sand contact they bear the whole weight and provide all the forward force. This study elucidates aspects of the integuments.

Material and Methods: A stereo microscope, scanning electron microscope (SEM), and confocal scanning laser microscope were used to observe these integuments. Their surface structure was shown accurately in photographs. An SEM equipped with energy dispersive spectroscopy was used to check element contents of the upper and bottom areas and those on the lateral area of the 3rd toe.

Results: The content of some chemical elements on the upper area (Mg 2.04%, Si 0.18%, P 1.97%, Ca 0.59%, and S 0.69%) was higher than that of the bottom area (Mg 0.14%, Si 0.09%, P 0.10%, Ca 0.28%, and S 0.90%). Zinc was the particular element on the upper area, while sodium, chlorine, and potassium were the specific elements on the bottom area. The parts which must withstand different frictions contained different chemical compounds.

Conclusion: The microscopic plane with layer-like structure and stripes may contribute to the wear-resistance of the papillae. The polygonal and prism structures are helpful to fix papillae in a firmer way.
Limitations of urban development in land of social origin: the case of the metropolitan area of the city of Toluca (ZMCT)
Authors: Jiménez-Sánchez Pedro Leobardo , Calderón-Maya Juan Roberto , Campos-Alanís Héctor 
Published: June 2016

Abstract
The paper analyses the occupation process of agricultural land with social origin and urban uses in the metropolitan area of the city of Toluca (ZMCT), and the barriers that the population and authorities have to face in order to regularize the settlements. A mixed research method was applied, which included the use of quantitative and qualitative methods, on the basis of a theoretical analysis, to build a methodological research model, which was applied to an empirical case in municipal and metropolitan areas. The analysis of the 14 municipalities that constitute ZMCT shows that the barriers for regularizing settlements in land of social origin are the result of legal/administrative inefficiencies due to the incapability of local city halls to address the collective needs of society.
Nobody’s Really Ever Asked Me Why: Anxiety as a Barrier to School Success
Authors: Kratt Diane M. 
Published: June 2016

Abstract
Children’s mental health can be a barrier to school success. School-based mental health services exist and research has shown positive results with the implementation of them. However, students spend the majority of their school time with a teacher and very little research exists on the role of a teacher in regards to students with mental health conditions. In this study, a college student shares his life-long experiences on being a student living with anxiety. What can educators learn from someone like him?
