HUBBLE SPACE TELESCOPE IMAGING OF GLOBULAR CLUSTERS IN TWO FACE-ON LOW SURFACE BRIGHTNESS GALAXIES UGC 5981 AND UGC 6614

We present a study searching for globular cluster systems (GCSs) of two face-on low surface brightness galaxies (LSBGs), UGC 5981 and UGC 6614. Based on HSTWFPC2 images of F555Wand F814W filters, we detect 12 and 18 GC candidates for UGC 5981 and UGC 6614, respectively. Although these two LSBGs have very different bulge properties, they have very similar specific frequencies (SN) of 0.1. However, S N ~ 0.1 is quite small even for their late morphological types, albeit within errors. This suggests that LSBGs have had star formation histories lacking dominant initial starburst events while accumulating their stellar masses through sporadic star formation activities.
INVESTIGATION OF FOLD-DEPENDENT BEHAVIOR IN AN ORIGAMI-INSPIRED FSS UNDER NORMAL INCIDENCE

Frequency selective surfaces (FSS) filter specific electromagnetic (EM) frequencies defined by the geometry and often fixed periodic spacing of a conductive element array. By embedding the FSS pattern into an origami structure, we expand the number of physical configurations and periodicities of the FSS, allowing for fold-driven frequency tuning. The goal of this work is to examine the folddependent polarization and frequency behavior of an origami-inspired FSS under normal incidence and provide physical insight into its performance. The FSS is tessellated with the Miura-ori pattern and uses resonant length metallic dipoles with orthogonal orientations for two primary modes of polarization. A driven dipole model with geometric morphologies, representative of the folding operations, provides physical insight into the observed behavior of the FSS. Full-wave simulations and experimental results demonstrate a shift in resonant frequency and transmissivity with folding, highlighting the potential of origami structures as an underlying mechanism to achieve fold-driven EM agility in FSSs.
The Validity of a Design Technology for a Higher Education Quality Assurance System Based on the EFQM Model

In current conditions, higher educational institutions have to develop innovative mechanisms of education quality assurance independently. One such mechanism is the implementation of the European Foundation for Quality Management (EFQM) model, although the 9001:2001 International Organization for Standardization (ISO) model is widely implemented in the higher education system of Kazakhstan. International Organization for Standardization (ISO) model is widely implemented in the higher education system of Kazakhstan. In-depth theoretical and methodological studies developed a design technology for a quality assurance system. The purpose of this study is to confirm the validity of this technology, which is why the study sets the following tasks: 1) to determine the validity criteria for the developed technology; 2) to show that the developed technology meets the validity criteria. An important result of this study is that it substantiated the criteria of the selected types of technology validity: construct, criterion, and content. The study proved that the developed technology met the criteria of validity, which was the main result. This allows recommending higher educational institution in Kazakhstan to implement this technology.
YIELD POTENTIAL OF DIRECT SEEDED RICE (ORYZA SATIVA L.) AS INFLUENCED BY DIFFERENT SEEDING TECHNIQUE AND WEED MANAGEMENT PRACTICES

A field experiment was conducted during kharif season 2007-08 at Crop Research Center of SVPUAT, Meerut and Uttar Pradesh to find out the suitable crop establishment method and weed management practices in rice. Effective tiller, (297.98), grain/panicle (143.84), grain yield (3711 kg/ha), straw yield (5808 kg/ha) and harvest index (38.98 %) produced higher under broadcast in puddled condition. Among weed management practices, higher number of productive tillers/m 2 , panicle length (28.79 cm), grains/panicle (148.3), test weight (22.48 g) and grain yield under butachlor @1.5 kg a.i. as pre-emergence followed by almix @ 4 g a.i./ha as post-emergence. Straw yield (5989 kg/ha) was significantly higher under butachlor @1.5 kg a.i. as pre-emergence followed by one
Highspeed laser welding of steel using a high-power single-mode continuous-wave fiber laser

Since a few years, high brilliance laser sources find their way into laser material processing. Laser micro processing by applying high brilliance laser radiation up to 3 kW of continuous wave laser power in combination with ultrafast beam deflection systems has been successfully demonstrated in 2008 for the first time. In the fields of laser welding, high brilliant laser radiation was mainly used for micro welding, but up to now the macro range is still insufficiently investigated. Hence, this study reports on detailed investigations of high speed laser welding of different steel grades, performed with a high power single mode fiber laser source. The laser beam was deflected relative to the sample by using both a fast galvanometer scanner system with f-theta focusing objective and a linear axis in combination with a welding optic, respectively. In the study, the mainly process influencing parameters such as laser power, welding speed, thickness of the metal sheets, angle of incidence and laser beam spot size were varied in a wide range. The weld seam quality was evaluated by structural analyses, static tensile tests and EDX measurements. Finally, the laser welding process has been optimized for different weld seam geometries, for example bead-on-plate welds and butt welds.
Analytical solutions of linked fault tree probabilistic risk assessments using binary decision diagrams with emphasis on nuclear safety applications

This study is concerned with the quantification of Probabilistic Risk Assessment (PRA) using linked Fault Tree (FT) models. Probabilistic Risk Assessment (PRA) of Nuclear Power Plants (NPPs) complements traditional deterministic analysis; it is widely recognized as a comprehensive and structured approach to identify accident scenarios and to derive numerical estimates of the associated risk levels. PRA models as found in the nuclear industry have evolved rapidly. Increasingly, they have been broadly applied to support numerous applications on various operational and regulatory matters. Regulatory bodies in many countries require that a PRA be performed for licensing purposes. PRA has reached the point where it can considerably influence the design and operation of nuclear power plants. However, most of the tools available for quantifying large PRA models are unable to produce analytically correct results. The algorithms of such quantifiers are designed to neglect sequences when their likelihood decreases below a predefined cutoff limit. In addition, the rare event approximation (e.g. Moivre’s equation) is typically implemented for the first order, ignoring the success paths and the possibility that two or more events can occur simultaneously. This is only justified in assessments where the probabilities of the basic events are low. When the events in question are failures, the first order rare event approximation is always conservative, resulting in wrong interpretation of risk importance measures. Advanced NPP PRA models typically include human errors, common cause failure groups, seismic and phenomenological basic events, where the failure probabilities may approach unity, leading to questionable results. It is accepted that current quantification tools have reached their limits, and that new quantification techniques should be investigated. A novel approach using the mathematical concept of Binary Decision Diagram (BDD) is proposed to overcome these deficiencies. BDDs have the remarkable properties of having complexity that is not related to the number of prime implicants of the encoded Boolean formula and of
A New Species of Neyraplectana Ballesteros Marquez, 1945 (Oxyuridae: Cosmocercinae) From Intestine of Bull Frog, Rana tigrina Anura:

- A new species of oxyuridean nematodes, Neyraplectana fatehpurensis n.sp. (Oxyuridae: Cosmocercinae) has been collected from small intestine of bull frog, Rana tigrina (Anura: Dicroglossidae) in North India during one year (2008-2009) uninterrupted investigation and substantiated by the application of polythetic divisive classificatory system. Sums of 257 bull frogs (male 159; female 98) were examined and 239 specimens, Neyraplectana sp. (male 97; female 142) recovered during parasitological investigation. The numerical validation of newer nematodes N. fatehpurensis n.sp. were based on the morphotaxometry of 33 specimens (male 12; female 21). The worms were typically characterized by paired equal spicules, absence of a gubernaculum and plectane, 5 pairs of preanal, 2 pairs adanal and 10-11 pairs post anal papillae, sub-equatorial vulva and in utero embryonated eggs.
Effects of weather on human capital in Vietnam

This study examines the effects of concurrent weather, corresponding to test sites as well as three-year consolidated weather conditions at high school time, on the math test scores of census examinees participating in the Vietnamese national entrance examinations to universities and colleges on July 4 and 15, 2009. Using individual first difference, I find that the maximum temperature of the day, 30 to 32°C (86-89.6°F), which is slightly below the usual average in all July between the years 1950-2009, benefitted examinees most. My analysis demonstrates that female testers were more vulnerable to harsh temperature and extreme weather but also more physically adaptive to temperature than males. Extreme weather occurring at the high school, especially during the school calendar, has a negative effect on the test scores.
Research on heterogeneity of children morbidity rate in Saint Petersburg

In the paper we present a research on heterogeneity of Saint Petersburg districts with respect to children morbidity rate. We used methods of cluster analysis for discovering groups of similar districts. As most of present distances work well with long time series but have biased results for short ones, the dissimilarity measure for short time series based on its characteristics is proposed. We constructed several clustering models to determine clusters which did not depend on the method. Five objects (districts) were distributed to several clusters in different models. For dealing with this problem an heuristic algorithm for inclusion of indeterminate objects to potential clusters was built. As a result we got three groups of districts which were similar in some sense. Mathematics Subject Classification: 62-07
Operational stability and kinetics of lactose hydrolysis by β- galactosidase from Kluyveromyces fragilis

The kinetic modeling of the lactose hydrolysis and the operational stability of the enzyme β-galactosidase of Kluyveromyces fragilis was determined using as substrate skimmed powdered milk, reconstituted in a way to supply two lactose concentrations: 5% and 10% (w/v). For the operational stability both lactose concentrations were studied in the presence and in the absence of the buffer pH 6.5. Every 40 minutes the residual activity was determined by the method of the initial velocities. The experimental results showed that the buffer leads to enzyme inactivation. However, for lactose solutions without buffer, the residual activity only declines 15% in 6 hours and later it decreases abruptly. In the kinetic modeling the hydrolysis reaction was led to 40 o C/7h, being used enzyme concentrations equivalent to 1500 and 8100 LAU/L. The adjusted model allowed us to conclude that it is necessary to use the quantity of 3450 LAU/L of the enzyme to obtain the hydrolysis from 70% to 80% of the milk lactose in two to three hours of reaction.
Novel and Efficient approach for Duplicate Record Detection

Similarity check of real world entities is a necessary factor in these days which is named as Data Replica Detection. Time is an critical factor today in tracking Data Replica Detection for large data sets, without having impact over quality of Dataset. In this system primarily introduce two Data Replica Detection algorithms, where in these contribute enhanced procedural standards in finding Data Replication at limited execution periods. This system contribute better improvised state of time than conventional techniques. We propose two Data duplicate record detection algorithms namely progressive sorted neighbourhood method (PSNM), which performs best on small and almost clean datasets, progressive blocking (PB), and parallel sorted neighbourhood method which performs best on large and very grimy datasets. Both enhance the efficiency of duplicate detection even on very large datasets.
Complementarity in the adoption of traceability of beef cattle in Brazil

Complementarity is an interesting approach to explain technology adoption. Taking account the other activities the farm performs in its production strategy can help understanding the decision on the adoption of new agricultural technology. This paper aims to evidence the existence of synergic effect resulting from the joint adoption of feedlot and traceability certification of beef cattle in Brazil. A sample of 84 beef cattle farms provided data to test hypotheses by using an OLS regression model. A measure of performance – revenue – is regressed on variables representing both isolated and joint adoption of capital-intensive production system and traceability. The results suggest the existence of synergic effect when joint adoption takes place. Joint adoption is influenced by a set of management practices, such as forward contracts, training of employees and zootechnical performance control, which are shared by both capital-intensive production systems and traceability.
Effects of low Light on Terpenoid Indole Alkaloid Accumulation and Related Biosynthetic Pathway Gene Expression in Leaves of Catharanthus roseus Seedlings

Catharanthus roseus (L.) G. Don, an important medicinal plant, produces the powerful alkaloids vinblastine (VBL) and vincristine (VCR), which are known for their remarkable inhibitory activity against tumor cells. This paper is the result of a study on the effects of low light/UV light on the contents of chlorophyll and alkaloids, and on the expression of terpenoid indole alkaloids (TIAs) biosynthesis pathway genes in the leaves of aseptic C. roseus seedlings. A plastic film treatment first induced a slight increase and then a significant decrease (p＜0.05) in the total chlorophyll content, and a lower chlorophyll a/b ratio. The amounts of vindoline (VIN) and catharanthine (CAT) followed the identical pattern under plastic film but the content of VBL, generated by its precursors VIN and CAT, increased gradually until reaching a maximum (0.028 mg g^(-1)±0.0051) on the 15th day of treatment. The plastic film also induced the expression changes of TIA biosynthesis pathway genes. The further correlation analysis between alkaloid content and these genes transcriptional levels indicated that VIN accumulation was significantly correlated with the gene expression of desacetoxyvindoline-4-hydroxylase (D4h) and deacetylvindoline-4-O-acetyl transferase (Dat), and CAT accumulation was significantly correlated with strictosidine synthase (Str) gene expression (p＜0.05). Therefore, the low light treatment with plastic film accelerated the accumulation of VBL in the leaves of C. roseus seedlings, which may have practical significance in the production of VBL.
Healthcare Demographics and Specialty Variation in Atopic Dermatitis: A Retrospective Cohort Analysis

Importance: Atopic dermatitis (AD) is a common chronic skin disease with significant comorbidities and a dramatic impact on quality of life. Despite this, there is little published information about healthcare utilization patterns for adults and children with AD. Objective: To examine healthcare utilization for patients with AD who are cared for in a regional academic medical center. Design: Retrospective cohort analysis. Setting: A mixed urban, suburban and rural catchment in the Western NY region. Participants: All patients seeking medical care for their AD from March of 2011 to September 2015. Exposure(s) for observational studies: Active AD. Main Measure(s): Age, sex, race, ethnicity, (demographics) and medical specialty (healthcare utilization). Patients were stratified and analyzed by age group. Results: Adult AD patients (n=767) accounted for 38.2% of the AD population seeking healthcare in our system with a mean age of 42.7 ± 18.7 years. Among adults, females were seen more commonly than males (65.3% vs. 34.7%). In contrast, both genders were equally represented in the pediatric population ( 18 years; 35.2%). Dermatologists cared for the majority of patients (35.2%), followed by pediatricians (25.7%) and family medicine physicians (10.1%). African-Americans were nearly 3 times more likely than Caucasians to visit primary care physicians for their initial AD management (p<0001). Conclusions and relevance: This study demonstrates that adult AD patients account for over a third of all AD visits in a regional academic medical center. Dermatologists managed the greatest number of AD patients, and the pediatric population was notable for a greater proportion of African American patients relative to the adults. This disparity between the proportions of African Americans in pediatric vs adult patients may reflect reduced access to care for adults. Alternatively, African-Americans may simply have a greater prevalence of pediatric onset AD coupled with greater disease resolution prior to adulthood. African-Americans also appear to seek
Exit from Exporting: Does Engagement in Transnational Networks Matter?

The aim of this paper is to investigate whether the probability of ceasing exports is lower for firms that are integrated in transnational production chains, once other firm characteristics are controlled for. On the basis of the estimation of a random-effects probit model with panel data, we find that the superior characteristics of firms involved in global networks (in terms of productivity, foreign ownership and skilled labor) explain their greater resistance to losing their status as exporters. However, for small firms, even when these distinctive features are controlled for, integration in international networks plays an important role in continuing to export. Thus, it seems that small firms which participate in networks have an added advantage which enables them to confront the uncertainty of foreign markets in better conditions and translates to a lower likelihood that they will stop exporting.
Municipal Solid Waste Management in Malaysia: Current Practices, Challenges and Prospect

Over the past decade, generation of municipal solid wastes (MSW) in Malaysia has increased more than 91%. However, MSW management in Malaysia can be considered relatively poor and disorganised. The most preferred of MSW disposal method in Malaysia is through landfilling due to several factors. This method is not sustainable and brings a lot of problems. This paper reviews the characteristics of Malaysian MSW, reports the current practices of MSW management, and provides some suggestions to improve MSW management system in Malaysia.
Efficacy of selected Pseudomonas strains for biocontrol of Rhizoctonia solani in potato.

Thirty seven bacterial isolates from faba bean (Vicia faba L.) root-nodules were screened for their antagonistic activity against eight Rhizoctonia solani strains isolated from infected potato (Solanum tuberosum L.) tubers. Two bacterial strains (designated as Kl.Fb14 and S8.Fb11) gave 50% in vitro inhibition of R. solani mycelial growth. 16S rDNA sequence analysis indicated that strain Kl.Fb14 exhibited 99.5% identity with Pseudomonas moraviensis, and that S8.Fb11 exhibited 99.8% identity with Pseudomonas reinekei. Greenhouse trials in soil showed that strain S8.Fb11 reduced the percentage of sclerotia on potato tubers and amounts of tuber infection for the potato cultivars Spunta and Nicola. In a field trial conducted in South Tunisia, infection with R. solani reduced potato yield by approximately 40% for ‘Spunta’ and 17% for ‘Nicola’; about 20% of the total tuber production was severely infected. However, when potato tubers were treated with strain S8.Fb11 prior to sowing, disease incidence was reduced to 6% of total production with low infection levels; potato yield was enhanced by about 6 kg per 10 m row in comparison to R. solani infected plants. The second selected Pseudomonas sp. (strain Kl.Fb14) did not affect either the levels of sclerotia on tubers or potato yield.
Relative impact of insolation and the Indo-Pacific warm pool surface temperature on the East Asia summer monsoon during the MIS-13 interglacial

During Marine Isotope Stage (MIS)-13, an interglacial about 500 000 years ago, the East Asian summer monsoon (EASM) was suggested exceptionally strong by different proxies in China. However, MIS-13 is a weak interglacial in marine oxygen isotope records and has relatively low CO2 and CH4 concentrations compared to other interglacials of the last 800 000 years. In the meantime, the sea surface temperature (SST) reconstructions have shown that the warm pool was relatively warm during MIS-13. Based on climate modeling experiments, this study aims at investigating whether a warmer Indo-Pacific warm pool (IPWP) can explain the exceptionally strong EASM occurring during the relatively cool interglacial MIS-13. The relative contributions of insolation and of the IPWP SST as well as their synergism are quantified through experiments with the Hadley Centre atmosphere model, HadAM3, and using the factor separation technique. The SST of the IPWP has been increased based on geological reconstructions. Our results show that the pure impact of a strong summer insolation contributes to strengthen significantly the summer precipitation in northern China but only little in southern China. The pure impact of enhanced IPWP SST reduces, slightly, the summer precipitation in both northern and southern China. However, the synergism between insolation and enhanced IPWP SST contributes to a large increase of summer precipitation in southern China but to a slight decrease in northern China. Therefore, the ultimate role of enhanced IPWP SST is to reinforce the impact of insolation in southern China but reduce its impact in northern China. We conclude that a warmer IPWP helps to explain the strong MIS-13 EASM precipitation in southern China as recorded in proxy data, but another explanation is needed for northern China.
In vitro antioxidant and antimicrobial activity of anthotaxy extracts from Dendranthema morifolium (Ramat.) Tzvel. and Chrysanthemum indicum L.

Dendranthema morifolium (Ramat.) Tzvel. and Chrysanthemum indicum L. are two traditional Chinese medicines, which were often obscure in prescriptions. In this study, the aqueous and ethanolic anthotaxy extracts from D. morifolium (Ramat.) Tzvel. and C. indicum L. , were evaluated for their antioxidant and antimicrobial properties. Ethanolic extracts showed higher contents of both total phenolics and flavonoids than aqueous extracts. The total phenolics and flavonoids contents in both aqueous and ethanolic extracts were in the order of D.morifolium (Ramat.) Tzvel. > C. indicum L. Using 1,1-diphenylpicrylhydrazyl (DPPH) assays, the concentrations providing 50% inhibition (IC50) values of aqueous extracts from D.morifolium (Ramat.) Tzvel. and C. indicum L. were 2.26 and 2.93 mg/ml, respectively, whereas the IC50 values of ethanolic extracts were 0.38 and 1.34 mg/ml, respectively. In sum, the antioxidant activities of ethanolic extracts from both D. morifolium (Ramat.) Tzvel.and C. indicum L. were better than aqueous extracts, and in the order of D. morifolium(Ramat.) Tzvel. > C. indicum L. The ethanolic extracts exhibited moderate antimicrobial activities, whereas the aqueous extracts showed poor antimicrobial properties in our test system. Key words: Dendranthema morifolium (Ramat.) Tzvel. , Chrysanthemum indicum L. , antioxidant activity, antimicrobial activity.
