Influence of Magnetic Field on the Threshold Current, Temperature Characteristics, and on the Output Power in AlGaInP Multiple Quantum Well Laser

In this paper we report the effects of relatively weak magnetic fields (up to 2T) on the threshold current, temperature characteristics and output power of AlGaInP MQW laser. The threshold current and temperature characteristics increased while the output power decreased by applying the magnetic field at different directions with respect to the quantum well plane. This paper presents a new insight into the mechanism that influence changes in the properties of MQW laser on application of magnetic fields based on the dynamics of electron-hole recombination.
Comparison of Quality of Life Between Iranians Using Two Implant-Retained Overdenture Prosthesis and Conventional Complete Denture

Background: Clinicians and policymakers are recognizing the importance of measuring health-related quality of life (HRQL) to inform patient management and policy decisions. Objectives: With regard to relation between cultural differences and quality of life (QoL), in this study the QoL of Iranian patients with conventional complete denture and implant-retained overdenture prosthesis according to the increasing penchant of use of implant-retained overdenture prosthesis and lack of studies in this field in our country, has been compared. Patients and Methods: In this cross-sectional study, cluster sampling was conducted in two stages and 90 edentulous patients (45 patients with conventional complete dentures for two jaws (CD group) and 45 patients with a conventional maxillary complete dentures and implant-retained mandibular denture based on two intercanine implants (IOD group)) with the age of above 35 years were selected according to our inclusion criteria. After obtaining permission from the patients, who had been treated at the selected healthcare and medical treatment centers of Tehran, basic information was obtained by a checklist, including gender, age, educational status and housing status; and QoL was measured by a questionnaire of oral health impact profile (OHIP-20). Results: In the group of IOD, 55.6% of the patients had "good" QoL vs. 46.7% of the patients in CD group. Three patients (6.6%) in both groups had "poor" QoL. No significant relationship was observed between demographic factors and different dimensions of QoL, except the average of "psychological disability" in the patients of CD group, which was higher in women. Conclusions: According to this study results, implant-retained overdenture prosthesis provided better QoL for Iranian patients.
Movilidad intergeneracional y emparejamiento selectivo en España

This paper examines the role of assortative mating in the intergenerational economic mobility in Spain. Sons and daughters usually marry individuals with similar characteristics, which may lower mobility. Our empirical strategy employs the Two-sample two-stage least squares estimator to estimate the intergenerational income elasticity in absence of data for two generations not residing in the same household. Our findings suggest that assortative mating plays an important role in the intergenerational transmission process. On average about 50 per 100 of the covariance between parents’ income and child family’s income can be accounted for by the person the child is married to
Oxygen Delignification of High-kappa Number Pine Kraft Pulp

The possibility of producing easy bleachable pulp (kappa number < 16) from high kappa number (68) pine kraft pulp through its oxygen delignification has been studied. The effect of the application of peroxy compounds in the oxygen delignification sequences of such pulps was also established. The yield and properties thus produced easy bleachable pulps were compared to the properties of pulp having similar bleaching susceptibility, produced in a conventional method (i.e. by wood pulping to kappa number approx. 30 and then oxygen delignification). The effect of factors such as: higher pH of medium, elevated temperature and presence of metal ions on stability of peracetic acid solution was also determined. The most important conclusion from carried out studies was finding that fibrous semi product produced in the process of oxygen delignification of pine kappa number 68 pulp with or without the use of peroxy compounds show higher yield (by approx. 2.5% on wood) compared with pulps produced by means of conventional method.
Functional Characterization of Variations on Regulatory Motifs

Transcription factors (TFs) regulate gene expression through specific interactions with short promoter elements. The same regulatory protein may recognize a variety of related sequences. Moreover, once they are detected it is hard to predict whether highly similar sequence motifs will be recognized by the same TF and regulate similar gene expression patterns, or serve as binding sites for distinct regulatory factors. We developed computational measures to assess the functional implications of variations on regulatory motifs and to compare the functions of related sites. We have developed computational means for estimating the functional outcome of substituting a single position within a binding site and applied them to a collection of putative regulatory motifs. We predict the effects of nucleotide variations within motifs on gene expression patterns. In cases where such predictions could be compared to suitable published experimental evidence, we found very good agreement. We further accumulated statistics from multiple substitutions across various binding sites in an attempt to deduce general properties that characterize nucleotide substitutions that are more likely to alter expression. We found that substitutions involving Adenine are more likely to retain the expression pattern and that substitutions involving Guanine are more likely to alter expression compared to the rest of the substitutions. Our results should facilitate the prediction of the expression outcomes of binding site variations. One typical important implication is expected to be the ability to predict the phenotypic effect of variation in regulatory motifs in promoters.
Health promotion for young patients with haemophilia.

The haemophilia treatment centre of the Clinic for Children and Youth Medicine in Jena extends medical care by health-promotion measures, namely: health counselling, adjuvant exercise therapy and school sports. In addition to the regular medical checks at the treatment centre patients are examined regarding physical fitness, joint situation, quality of life in general and disease-specific manner, as well as psycho-social and nutritional behaviour. Findings and medical results of the examinations are integrated into an individual advice on therapy, school sports, and health recommendations. This aimed at strengthening health-related resources and minimizing potential injuries. First long-term evaluation shows an increase of activity behaviour and physical fitness without increasing bleeding rate and maintained joint function. CONCLUSION Combining functional prevention diagnostics and individual health counselling shows signs of improved patient's health knowledge, self-competence and physical fitness.
"Righting it up": an interplay-based model for analyzing extreme right dynamics in Romania

The purpose of this paper is two-fold. First, it aims to offer a model for the analysis of rightwing extremism in Central and Eastern Europe (and elsewhere), which focuses – at its core – on the interplay between political agents, structural and cultural conditionings. Employing Archer’s (1995, 1996, 2000) morphogenetic approach, it shows that the success of right-wing extremism depends on whether the agent-structure-culture interplay results in structural and/or cultural elaboration (morphogenesis) or reproduction (morphostasis). Second, the paper employs this framework in an analysis of contemporary Romania. Here, it argues that the decline of extreme right parties against the background of continuous support for and presence of right-wing extremism within Romanian society is a consequence of how logical contradictions within and between the structural and the cultural systems have been negotiated by political actors.
ASSESSMENT OF DIESEL FUEL UPTAKE BY FUNGI ISOLATED FROM PETROLEUM CONTAMINATED SOIL

The aim of this research was to isolate and identify the fungi from petroleum-contaminated soil, to test their ability to grow in the presence of diesel fuel and uptake it in solid and broth media. Among 16 isolated and identified filamentous fungi, six were tested to determine their growth on media enriched with diesel fuel as a sole carbon source. All tested isolates showed different degree of diesel fuel utilization. Colony diameter was measured, where the highest colony growth dynamics ratio was demonstrated for Penicillium sp. (74.16%) and Cladosporium sp. (71.43%), and the lowest for Absidia spinosa (23.15%). Results of dry mass measurements demonstrated the highest potential of A. strictum (71.43%) to utilize diesel fuel in broth medium. All other tested isolates showed insignificant dry mass production ratio values. The highest utilization degree was documented for A. strictum (60.28 %) and the lowest for Penicillium sp. (25.18%).
Black carbon-induced snow albedo reduction over the Tibetan Plateau: uncertainties from snow grain shape and aerosol–snow mixing state based on an updated SNICAR model

Abstract. We implement a set of new parameterizations into the widely used Snow, Ice, and Aerosol Radiative (SNICAR) model to account for effects of snow grain shape (spherical vs. nonspherical) and black carbon (BC)–snow mixing state (external vs. internal). We find that nonspherical snow grains lead to higher pure albedo but weaker BC-induced albedo reductions relative to spherical snow grains, while BC–snow internal mixing significantly enhances albedo reductions relative to external mixing. The combination of snow nonsphericity and internal mixing suggests an important interactive effect on BC-induced albedo reduction. Comparisons with observations of clean and BC-contaminated snow albedo show that model simulations accounting for both snow nonsphericity and BC–snow internal mixing perform better than those using the common assumption of spherical snow grains and external mixing. We further apply the updated SNICAR model with comprehensive in situ measurements of BC concentrations in the Tibetan Plateau snowpack to quantify the present-day (2000–2015) BC-induced snow albedo effects from a regional and seasonal perspective. The BC concentrations show distinct and substantial sub-regional and seasonal variations, with higher values in the non-monsoon season and low altitudes. As a result, the BC-induced regional mean snow albedo reductions and surface radiative effects vary by up to an order of magnitude across different sub-regions and seasons, with values of 0.7–30.7 and 1.4–58.4 W m−2 for BC externally mixed with fresh and aged snow spheres, respectively. The BC radiative effects are further complicated by uncertainty in snow grain shape and BC–snow mixing state. BC–snow internal mixing enhances the mean albedo effects over the plateau by 30–60 % relative to external mixing, while nonspherical snow grains decrease the mean albedo effects by up to 31 % relative to spherical grains. Based on this study, extensive measurements and improved model characterization of snow grain shape and aerosol–snow mixing state are urgently needed in order to precisely evaluate BC–snow albedo effects.
Epidemiological patterns of Tuberculosis disease in the Babol, Iran

Introduction: Almost one-third of the world’s population is at risk of exposure to tuberculosis (TB) infection. The aim of this study is to describe some patterns of TB in the Babol, Iran, to analyze the current situation and to improve the care of these patients. Methods: This was a cross-sectional study. The data were obtained from medical records pertained to patients with TB of Health Network of Babol County. The variables of interest were demographic characteristics and some clinical patterns. To describe data, indices such as mean ± SD and frequency (percent) was used. Furthermore, analysis of the data was performed by inferential statistical techniques of chi-square, independent samples t-test, and one-way analysis of variance test. Results: Two hundred patients with TB were enrolled. The average age of cases were 47.51 years [standard deviation (SD) = 21.36] and 58.5% of them were males. Age groups of 18-40 and over 60 years old comprised the majority of patients with TB 39.0 and 31.5%, respectively. The median interval time between beginning symptoms and confirmed diagnosis of TB was 56.5 days with interquartile range (IQR) of 56 days. The greatest of the time interval of beginning symptoms and diagnosis belonged to the age group of below 7 years old. The greatest time interval from confirmed diagnosis to treatment pertained to the age groups of 18-40 and 7-18, respectively. In terms of pulmonary TB, 120 (80.0%) were smear positive and 30 (20.0) smear negative. In terms of medicines given to the patients with TB, 181 (90.5%) were completed the treatment and improved, 6 (3.0%) absence of treatment, and 13 (6.5%) died as a result of TB and other causes.Conclusion: This study showed that adults and elderly comprise the highest proportion of TB. The primary prevention and control programs for education and timely referral to the Health Network may be effective in diminishing the morbidity due to TB.
A SMART NANOFIBROUS MATERIAL FOR ADSORBING

16 The combination of gold affinity for mercury with nanosized frameworks has allowed to design 17 and fabricate novel kinds of sensors with promising sensing features for environmental 18 applications. Specifically, conductive sensors based on composite nanofibrous electrospun layers 19 of titania easily decorated with gold nanoparticles were developed to obtain nanostructured 20 hybrid materials, capable of entrapping and revealing GEM traces from environment. The 21 electrical properties of the resulting chemosensors were measured. Few minutes of air sampling 22 were sufficient to detect the concentration of mercury in the air, in the range between 20-100 23 ppb, without using traps or gas carriers (LOD  1.5 ppb). Longer measurements allowed the sensor 24 to detect lower concentrations of GEM. The resulting chemosensors are expected to be low-cost, 25 very stable (due to the peculiar structure), and requiring low power, low maintenance and simple 26 equipment to work. 27
Aurora B kinase activity–dependent and –independent functions of the chromosomal passenger complex in regulating sister chromatid cohesion

The chromosomal passenger complex (CPC) is a master regulator of mitosis. CPC consists of inner centromere protein (INCENP), Survivin, Borealin, and the kinase Aurora B and plays key roles in regulating kinetochore–microtubule attachments and spindle assembly checkpoint signaling. However, the role of CPC in sister chromatid cohesion, mediated by the cohesin complex, remains incompletely understood. Here, we show that Aurora B kinase activity contributes to centromeric cohesion protection partly through promoting kinetochore localization of the kinase Bub1. Interestingly, disrupting the interaction of INCENP with heterochromatin protein 1 (HP1) in HeLa cells selectively weakens cohesion at mitotic centromeres without detectably reducing the kinase activity of Aurora B. Thus, through this INCENP–HP1 interaction, the CPC also protects centromeric cohesion independently of Aurora B kinase activity. Moreover, the requirement for the INCENP–HP1 interaction in centromeric cohesion protection can be bypassed by tethering HP1 to centromeres or by depleting the cohesin release factor Wapl. We provide further evidence suggesting that the INCENP–HP1 interaction protects centromeric cohesion by promoting the centromere localization of Haspin, a protein kinase that antagonizes Wapl activity at centromeres. Taken together, this study identifies Aurora B kinase activity–dependent and –independent roles for the CPC in regulating centromeric cohesion during mitosis in human cells.
Habitat Use and Diet of Astrochelys radiata in the Subarid Zone of Southern Madagascar

Abstract Astrochelys radiata is one of the threatened tortoise species of Madagascar. We studied their home range size, use of shelters, and diet in Tsimanampetsotsa National Park. The goal was to identify suitable habitats and food chemistry. These data could serve as bases for future evaluations of the suitability of habitats under altered environmental conditions, such as degradation and climate change. The study was performed with the help of radio-tracking in two different types of vegetation: dry deciduous forest on sand and spiny bush on limestone between November 2007 and October 2008. Monthly range sizes were 2.3 ha in the littoral forest and 1.4 ha on the limestone massif when calculated with the kernel method. Based on the minimum convex polygon, the values were 1.0 and 0.5 ha, respectively. Monthly range size did not vary significantly between sexes, but range sizes were larger in the littoral forest than on limestone. A. radiata chose shelters under trees with large trunk diameters (> 15-cm DBH) and lower heights than trees in representative samples in the habitats. Plant items eaten and not eaten by this species were analyzed for primary and secondary plant chemicals. A. radiata consumed a wide variety of plants. Its diet was composed of leaves (91%), flowers (5%), and fruits (4%) from 109 plant species. During the dry season, high energy content was the most important factor for food selection by A. radiata.
OXIDATIVE STRESS IN STREPTOZOTOCIN-INDUCED EXPERIMENTAL DIABETES IN RATS IS ASSOCIATED WITH CHANGES OF ANTIOXIDANT STATUS OF HEART TISSUE.

The present study was designed to evaluate the oxidative stress-related parameters in streptozotocininduced diabetes in rats. After 2, 3, 6 and 12 weeks of hyperglycaemia the enzymatic parameters were measured in heart tissue of diabetic and control groups. Superoxide dismutase, glutathione peroxidase and the glucose-6-phosphate dehydrogenase activities significantly increased at all time intervals. Catalase activity increased initially (after 2 and 3 weeks), decreased after 6 weeks and increased again at the 12th week of the experiment. Glutathione reductase activity increased initially (at 2nd week), decreased below control level after 3 weeks, and then increased again. Ascorbic acid concentration decreased after 3 and 6 weeks, and increased at the 6th and 12th weeks. The level of lipid peroxidation products was reduced after 2, 3 and 6 weeks of the experiment. After 12 weeks it was significantly elevated. These data suggest that chronic hyperglycaemia induces oxidative stress in the heart but the defense mechanisms in the heart tissue are fairly efficacious against oxidative injury.
Risk-Return Trade-Off for European Stock Markets

This paper adopts dynamic factor models with macro-fi? nance predictors to revisit the intertemporal risk-return relation in ? five large European stock markets. We identify country specifi? c, Euro area, and global factors to determine the conditional moments of returns considering the role of higher-order moments as additional measures of risk. The preferred combination of factors varies across countries. In the linear model, there is a strong but negative relation between conditional returns and conditional volatility. A Markov switching model describes the risk-return trade-off well. A number of variables have explanatory power for the states of the European stock markets.
Investigation of Biomass Burning Chemical Components over Northern Southeast Asia during 7-SEAS/BASELInE 2014 Campaign

This study investigates the chemical components of biomass burning (BB) aerosols obtained from Doi Ang Khang (DAK; near BB source) and Chiang Mai University (CMU; an urban location) over northern Southeast Asia in dry season (March to mid-April) 2014. PM_(2.5) (particulate matter with an aerodynamic diameter less than or equal to 2.5 μm) samples were collected over a 24-h sampling period as a part of the Seven South East Asian Studies (7-SEAS)/BASELInE (BB Aerosols & Stratocumulus Environment: Lifecycles & Interactions Experiment) campaign. The collected aerosols were analyzed for mass concentrations of ions, metals and levoglucosan. The influence of air mass movements on aerosol species was also analyzed. The average PM_(2.5) mass concentrations at DAK (80.8-83.3 μg m^(-3)) and CMU (90.7-93.1 μg m^(-3)) were not significantly different (p ＞ 0.05) and well correlated (r = 0.8), and likely originated from similar source origins. The number of fire hotspots was particularly high during 20-21 March (greater than 200) and, consequently, peaks of PM_(2.5) were recorded at both sites. The most abundant elements at both sampling sites were K (49-50% of total elements), Al (26-31%), Mg (16%) and Zn (4-7%), whereas SO_4^(2-) (30-38% of total ions), NO_3^- (13-20%), Na^+ (16-20%) and NH_4^+ (14-15%) were the most abundant ions. Concentrations of levoglucosan and K^+ (BB tracers) were well correlated (r = 0.5 for CMU and 0.7 for DAK) confirming that the PM_(2.5) detected in these areas were mainly influenced by BB activity. Principal component analysis (PCA) revealed that BB, road traffic, agricultural activity and soil re-suspension were plausible sources of PM_(2.5) over the study locations. Apart from local sources, the influence of long-range transport was also investigated by way of three-day backward trajectory analysis.
