Reordering of magnetic colloid structures in external magnetic fields

Field-induced local ordering within a cobalt-based magnetic colloid has been studied with polarized small-angle scattering by turning the direction of the external magnetic field. By analysing the nuclear–magnetic cross term we were able to separate the scattering contributions from dipolar chains and domains of pseudo-crystalline hexagonal arrangements. The magnetic moments were found to be aligned along the external magnetic field and to follow the change of the field direction. The observed variation of the particle moments must give rise to a rearrangement of the local hexagonal structure with respect to the new field direction to explain the scattering pattern. We confirm this by two-dimensional simultaneous least-squares fits for different Q ranges [where Q = 4\pi \sin (\theta) / \lambda, λ is the X-ray wavelength and 2θ is the scattering angle] with a model containing a core–shell particle form factor and a structure factor composed of Gaussian peaks and contributions from polydisperse cylinders.
The Minimum Wage : Labor Market Consequences in the Czech Republic *

This paper aims to quantify the impact of the minimum wage on labor market performance in the Czech Republic. Using regional data for 1995–2004, it estimates the effect of the minimum wage adjusted for the regional wage differential on regional unemployment. Consequently, using detailed individual data from 2004/2005, we analyze the annual hikes in the minimum wage, which allow us to estimate employment probabilities for workers with a wage level at, or close to, the new minimum wage. The aim is to reveal whether the most endangered groups of workers exhibited significantly different subsequent employment probabilities. Our results reveal that the minimum wage has had a significant impact in terms of increasing regional unemployment and reducing the employment probabilities of low-paid workers.
Cervical Cancer Knowledge and Screening Practices among Women of Reproductive Age in Benin City , Edo State

BACKGROUND Cervical cancer remains a major public health challenge in developing countries including Nigeria and contributes signicantly as a major cause of death among women of reproductive age. This study was conducted to assess knowledge and cervical cancer screening practices among women of reproductive age in Benin City, with a view to planning programs to improve cervical cancer screening uptake in our environment. METHODOLOGY A descriptive cross sectional study design was utilized for this study involving researcher administration of semi-structured questionnaires to 235 consenting women of reproductive age (15-49years) attending immunization clinics in Benin City. The data collected were analyzed using IBM Statistical Package for Social Sciences (SPSS) version 22.0 with statistical signicance set at p<0.05 and 95% Condence Interval. RESULTS The mean age and parity of respondents studied was 28.8 ± 7.4 years and 2.19 ±1.85children respectively. One hundred and thirteen (48.1%) of the women studied were aware of cervical cancer with 57(50.4%) having good knowledge of cervical cancer. Furthermore, in relation to cervical cancer screening only 31(27.4%) of respondents studied had previously been tested. In relation to knowledge on cervical cancer, primary level of education (OR=0.095; 95% CI=0.019 – 0.475) was the only signicant predictor identied, while parity (OR=0.157; 95% CI=0.025 – 0.969) was the only signicant predictor identied that inuenced screening practice. CONCLUSION This study identied poor knowledge of cervical cancer and low practice of cervical screening among women of reproductive age. There is need to create and strengthen cervical cancer awareness campaign and screening practices among women.

Quantum metrology triangle experiments: a status review

Quantum metrology triangle experiments combine three quantum electrical effects (the Josephson effect, the quantum Hall effect and the single-electron transport effect) used in metrology. These experiments allow important fundamental consistency tests on the validity of commonly assumed relations between fundamental constants of nature and the quantum electrical effects. This paper reviews the history, results and the present status and perspectives of quantum metrology triangle experiments. It also reflects on the possible implications of results for the knowledge on fundamental constants and the quantum electrical effects. In terms of relative standard uncertainty, the best result currently achieved is nine parts in 107, while the goal is to reduce the uncertainty down to below five parts in 107 in order to provide an impact on the adjustment of the physical constants’ values.
Convergence of pinching deformations and matings of geometrically finite polynomials

We give a thorough study of Cui’s control of distortion technique in the analysis of convergence of simple pinching deformations, and extend his result from geometrically finite rational maps to some subset of geometrically infinite maps. We then combine this with mating techniques for pairs of polynomials to establish existence and continuity results for matings of polynomials with parabolic points. Consequently, if two hyperbolic quadratic polynomials tend to their respective root polynomials radially, and do not belong to conjugate limbs of the Mandelbrot set, then their mating exists and deforms continuously to the mating of the two root polynomials.
Congruency effects of symbolic meaning in design and brand impressions: Effects on product and brand evaluation

Consumers are facing an increasingly difficult task when they go out to buy a product in the supermarket as the competition among brands increases. Building on previous studies, this research has sought to investigate the influences of congruency of product and brand design with respect to symbolic meaning on product and brand evaluations, as well as the role of tolerance for ambiguity in moderating this relationship. The results from this study show that congruency effects in products design and brand impressions work differently than expected yet still confirm the influence of congruency among sources of product and brand information on judgments pertaining to the brand and the product. Finding no influence of tolerance for ambiguity, it is argued that risk and uncertainty avoidance may both be an important factor in consumer preferences for products and brands. In addition, it is argued that consumers may construe their brand impressions on a holistic basis, putting the importance of congruency among product and brand elements in a new perspective. Practical implications as well as recommendations for future research are discussed.
Transforming Growth Factor Β: Clinical Significance and Peculiarities of Inheritance in Children with Atopic Dermatitis

Transforming growth factor β1 (TGF-β1) plays an important role in the pathogenesis of many allergic diseases, including atopic dermatitis (AD). Objective: to study the role of TGF-β1 in the pathogenesis of AD in children. Materials and methods. A survey was conducted of 34 patients with AD and 20 healthy children. TGF-β1 in serum were determined by ELISA using kits of Human TGF beta1 Platinum ELISA. Definition Arg25Pro gene polymorphism of TGF β1 was carried out using allele-specific polymerase chain reaction. Results. It was found that patients with AD showed a significant increase in the concentration of TGF-β in the serum (222,37±68,58 PG/ml) compared with the control group (3,03±0,41 ng/ml) [p = 0.001]. The concentration depends on the severity and duration of the illness. Frequency of genotypes for the polymorphism Arg25Pro TGF β1 gene among patients with AD had significant differences from the control group (p < 0.05). Moreover, among patients who are heterozygotes for the gene Arg25Pro TGF β1, was significantly more observed moderate (77.78 %) and severe (33,33%) the course of the disease. Conclusion. The obtained results confirm the importance of TGF-β1 in the pathogenesis of AD.
An Experimental Study of Combining a Photovoltaic System with a Heating System

Solar photovoltaic and thermal systems are potential solutions for current energy needs. One of the most important difficulties in using photovoltaic systems is the low energy conversion efficiency of PV cells and, furthermore, this efficiency decreases further during the operational period by increasing the cells temperature above a certain limit. In addition, reflection of the sun’s irradiance from the panel typically reduces the electrical yield of PV modules by 8-15%. To increase the efficiency of PV systems one way is cooling them during operation period. In this experimental study combination of a PV system cooled by a thin film of water with an additional system to use the heat transferred to the water has been considered. Experimental measurements for both combined system and conventional panel indicate that the temperature of the photovoltaic panel for combined system is lower compared to the conventional panel. The results show that the power and the electrical efficiency of the combined system are higher than the traditional one. Also since the heat removed from the PV panel by water film is not wasted, the overall efficiency of the combined system is higher than the conventional system.
Cubic-to-tetragonal phase transitions in Ag-Cu nanorods

Molecular dynamics simulations have been used to investigate the structural behavior of nanorods with square cross section. The nanorods consist of pure Ag and Cu phases or of three Ag and Cu domains in the sequence Ag-Cu-Ag or Cu-Ag-Cu. Ag and Cu domains are separated by coherent interfaces. Depending on the side length and the size of individual domains, Ag and Cu can undergo a transition from the usual face-centered cubic structure to a body-centered tetragonal one. Such transition can involve the whole nanorod, or only the Ag domains. In the latter case, the transition is accompanied by a loss of coherency at the Ag-Cu interfaces, with a consequent release of elastic energy. The observed behaviors are connected with the stresses developed at the nanorod surfaces.
LA FONCTION ET LA MORPHOLOGIE DENTO-FACIALE DANS LA DYSTROPHIE MUSCULAIRE DE DUCHENNE

Les effets de la Dystrophie Musculaire de Duchenne (DMD) sur la sphère oro-faciale ont été étudiés chez 16 patients et 16 sujets sains. La force masticatrice était plus basse pour les patients atteints de DMD, probablement en raison à l'atteinte progressive de la structure interne des muscles par la maladie. Une différence temporelle dans le début de l'atteinte de la musculature masséterine et de l'orbiculaire des lèvres semble donner un déséquilibre entre les forces orales. Ceci, combiné à l'augmentations de la taille de la langue, peut expliquer la survenue de malocclusions telles que des béances antérieures et latérales, un overjet diminué ainsi qu'une occlusion croisée postérieure due à un développement transversal disproportionné de l'arcade inférieure. A terme, ces maloclussions d'origine dentaire plutôt que squelettique peuvent fortement diminuer la capacité masticatoire chez ces patients dont l'esprérance de vie augmente avec l'amélioration de la prise en charge médicale.

Strategic entrepreneurial response of small and medium enterprises in developing economies

This study examined the influence of three dimensions of strategic entrepreneurial response, namely marketorientation, entrepreneurial orientation and networking capability on SME performance necessary for firms toface challenges in competitive environments. The research confirmed positive influence of the three dimensionsof strategic entrepreneurial response (SER), namely market orientation (MO), entrepreneurial orientation (EO)and network capabilities (NWC) on small and medium enterprise (SME) performance. The dimensions of SERexplained a significant amount of variance (50.1%) in SME performance, with the largest amount (27.1%) ofvariance accounted for by MO. The findings suggest that emphasis on MO is a firm’s strategic choice to generatestrategic information which forms a seedbed of opportunities from which entrepreneurial oriented firms identifyand proactively seize to build competitive advantage. Contrary to previous studies, which emphasized thatopportunity seeking behaviour is a domain of EO, this paper argues that MO is pivotal construct to the SER. Thispaper views EO as more driven by an advantage seeking behaviour rather than opportunity seeking behaviour asconceptualised before. With these findings, this paper suggest that sustained market orientation andentrepreneurial orientation cultures build opportunity seeking and advantage seeking behaviours, respectivelycrucial to create and sustain SME performance.
MICROBIOLOGICAL SAFETY OF STREET VENDED FRESH FRUIT JUICES, DRINKS AND CONVENTIONAL BLENDS IN MULTAN-PAKISTAN

The study aimed at exploring the safety of various fresh fruit juices, blends and drinks sold in the streets of Multan, Pakistan. The city was divided into 4 zones for the purpose of sample collection. Bacteriological analysis of 72 samples of fresh fruit juices, blends and drinks indicated the presence of total viable counts (2.48 ± 0.16 to 7.91 ± 0.62 log CFU/mL), total coliforms (0.70 ± 0.04 to 4.86 ± 0.29 log CFU/mL) and Escherichia coli (0.6 ± 0.03 to 3.83 ± 0.32 log CFU/mL). Qualitative data depicted apple juice to be highly contaminated with fecal coliforms and Salmonella spp. Coliforms prevalence was highest in Zone IV and Zone II while that of Salmonella spp. , in Zone IV and Zone III. The pragmatic levels of contaminants elucidate poor sanitary status of major entities deployed in juice manufacturing process adopted by the street vendors.
Epidemiological Analysis of Lymphoma Subtypes in a Reference Center in João Pessoa

A gradual increase in diagnosed cases of lymphoma has led to greater dissemination of relevant information and has simultaneously revealed a need to improve understanding of the pathology. The prevalence of lymphomas involves many factors that vary regionally, with regional differences in prognosis indeed playing a role in therapeutic decisions. This observational study aimed to retrospectively evaluate the prevalence of lymphoma subtypes diagnosed between 2011 and 2015 at the Napoleao Laureano Hospital, the largest hematology facility in Paraiba, northeastern Brazil and a state reference for hematological oncology. Immunohistochemistry findings and associated prognostic variables were analyzed, including calculation of prognostic indexes such as the international prognostic index (IPI), age adjusted IPI, National Comprehensive Cancer Network IPI (NCCN-IPI), mantle cell lymphoma IPI (MIPI) and follicular lymphoma IPI (FLIPI). The most noteworthy findings include the large number of young people diagnosed with aggressive disease, with poor prognostic indexes but low mortality rates, confirming the technical strength of the institution as reflected in the improved prognosis associated with the disease. The prevalence of Hodgkin lymphoma was found to be high, contradicting a considerable part of the international literature but in agreement with some studies conducted with pediatric populations in Brazil. In addition, the most prevalent subtypes of non-Hodgkin lymphoma, already well discussed in the international literature, were also represented in the present sample. All cases of lymphoma registered at this center were catalogued, with their prognoses and anatomopathological and immunohistochemical diagnoses being analyzed, consequently providing a better database for this geographical region of Brazil.
Financial Performance of Family Firms (Evidence from Selected Manufacturing Sectors of Pakistan)

The present study empirically investigates the impact of ownership structure on firm’s performance while controlling the effect of other firm specific characteristics (firm age, firm size, risk, leverage, profitability, payout and firm growth). Four years data i.e. 2006 to 2009 of 62 non-financial firms, listed at Karachi Stock Exchange, has been collected and analyzed by using latest panel estimation techniques. Main objectives of this study are to examine the performance of family versus non-family firms and the performers of founder versus descendant firms. Using Random effects Generalized least Square estimation techniques results reveal that in Pakistan family firms are associated with poor performance as compare to non-family firms. But results are only significant for overall sample of family firms and not for the founder and descendant ownership variables, individually.
Import tariff upstream versus export tax downstream: are they welfare equivalent?

Along the lines of the strategic trade policy inquiry under vertical structures we show that two rival governments may select different rates of export subsidies and import tariffs respectively upon their own industries even if their marginal costs are identical. Moreover, regardless of any combination of these policy instruments optimally introduced, we show that each nation's welfare level will remain the same and higher than that under free trade with no trade policy at all.
Droplet evaporation losses during sprinkler irrigation: an overview

A detailed understanding regarding the evaporation losses in sprinkler irrigation is important for developing as well as adopting appropriate water conservation strategies. To explain this phenomenon many theoretical and experimental studies have been conducted since the 1950‟s. Notwithstanding all these efforts, the contribution of droplet evaporation to the total evaporation losses during sprinkler irrigation is still a controversial issue in the irrigation community. There is a substantial difference among researchers regarding the magnitudes of the different components of the total evaporation in sprinkler irrigation especially droplet evaporation losses. Field studies reported that the droplet evaporation losses ranged from 2 – 45%, whereas theoretical studies indicated that it is less than 1%. This is due largely to the limitations of the traditional measurement methods. However, it is likely that these limitations can be overcome and accurate measurements obtained using the eddy covariance (ECV) technique.
Antidepressant Effect of Diclofenac against Experimental Parkinson’s Rat Model

Previous clinical studies confirm the presence of inflammatory mediators like tissue necrotic factor alpha (TNF-α) and interleukins-1β in depressive patients are the main cause of depression and the use of non-steroidal anti-inflammatory drugs (NSAIDs) especially cyclo-oxygenase-2 (COX-2) inhibitors are associated with a marked reduction in the symptoms of depression. In our study we investigated the role of diclofenac in ameliorating depression in chlorpromazine (CPZ) induced PD model. Forty Wistar albino rats were divided equally into 4 groups, Rats of group I (control) received only vehicles and had free access to food and water. Rats of groups II, III and IV were treated with chlorpromazine (3mg/kg/day ) via the intraperitoneal route once a day for 21 days. Diclofenac (20mg/kg/day) was given orally to group III and standard drug L-dopa/carbidopa (30mg/kg/day) orally was given to group IV for 21 days. Group II was negative control, and all treated group received 3mg/kg/day i.p CPZ for 21 days. CPZ was administered 30 min before the administration of test drugs, antidepressant effects of diclofenac were examined by using open field activity, cage crossing and forced swimming test. In the open field, diclofenac and standard drug (L-dopa/carbidopa) animals showed significant (P<0.001) improved number of square crossed in 10 minutes, increased grooming period and relatively more time spent in center of open field arena after 10 and 21 days as compared to CPZ group. In cage crossing diclofenac showed highly significant (P<0.001) improved activity of cage crossing after 21 days just similar to standard group (L-dopa/carbidopa), while CPZ significantly showed immobility and depressive behavior. In FST diclofenac was able to restore significantly the immobility time and decrease swimming effort as well as climbing duration induced by CPZ. Taken together, the present work evidenced antidepressant effects of diclofeanc. This may be through inhibiting depressive markers like TNF-α and IL-1β in brain compartments, and possibly nor-adrenergic mechanism could also play a role.
Improved Detection of Severe Storms Using Experimental Fine-Resolution WSR-88D Measurements

Doppler velocity and reflectivity measurements from Weather Surveillance Radar-1988 Doppler (WSR88D) radars provide important input to forecasters as they prepare to issue short-term severe storm and tornado warnings. Current-resolution data collected by the radars have an azimuthal spacing of 1.0° and range spacing of 1.0 km for reflectivity and 0.25 km for Doppler velocity and spectrum width. To test the feasibility of improving data resolution, National Severe Storms Laboratory’s test bed WSR-88D (KOUN) collected data in severe thunderstorms using 0.5°-azimuthal spacing and 0.25-km-range spacing, resulting in eight times the resolution for reflectivity and twice the resolution for Doppler velocity and spectrum width. Displays of current-resolution WSR-88D Doppler velocity and reflectivity signatures in severe storms were compared with displays showing finer-resolution signatures. At all ranges, fine-resolution data provided better depiction of severe storm characteristics. Eighty-five percent of mean rotational velocities derived from fine-resolution mesocyclone signatures were stronger than velocities derived from current-resolution signatures. Likewise, about 85% of Doppler velocity differences across tornado and tornadic vortex signatures were stronger than values derived from current-resolution data. In addition, low-altitude boundaries were more readily detected using fine-resolution reflectivity data. At ranges greater than 100 km, fineresolution reflectivity displays revealed severe storm signatures, such as bounded weak echo regions and hook echoes, which were not readily apparent on current-resolution displays. Thus, the primary advantage of fine-resolution measurements over current-resolution measurements is the ability to detect stronger reflectivity and Doppler velocity signatures at greater ranges from a WSR-88D.
