State of ovarIan follIcleS In hormonally treated pregnant eweS for collectIon of cumuluS-oocyte complexeS

Four Improved Vallachian ewes during anoestrus period of cycle and three pregnant ewes of the same breed were treated with natural progesterone 9% (cIDR-G) for 12 days. at the time of the device withdrawal ecG were injected i.m. at doses of 500 IU (pregnant ewes) or 1000 IU (non-pregnant ewes), respectively. In both groups blood was collected for determination of progesterone, oestradiol-17ß, and IGF-I concentrations. ewes of both groups were ovariectomized during laparotomy 48 to 62 hours after ecG injection. The numbers of both the types of follicles (<3 mm and ≥3 mm) were significantly higher (21.67±5.13; p<0.001 and 13.33±5.03; p<0.05) in pregnant ewes when compared to non-pregnant ewes (9.50±5.00 and 8.50±4.83), respectively. In pregnant ewes significantly larger amount of healthy follicles at the stage of selection (4.00±1.73; p<0.05) with 8.00 mm diameter of the largest follicle was noted in pregnant ewes in comparison to non-pregnant ewes where no follicle was seen at this stage on the ovarian surface. Remaining follicles underwent several types of atresia. The concentration of progesterone in pregnant ewes was significantly higher (5.40±1.62 ng.ml-1; p<0.001) than in non-pregnant ewes (2.65±0.29 ng.ml-1). The same result was obtained for concentrations of oestradiol-17ß (101.79±21.13 pg.ml-1 to 33.51±4.47 pg.ml-1). IGF-I was significantly lower (86.00±5.01 ng.ml-1 to 284.65±73.46 ng.ml-1) in pregnant ewes. These results validate the usefulness of influencing the folliculogenesis in ewes by a combination of natural progesterone and ecG treatment during the first third of pregnancy for collection of cumulus-oocyte complexes for in vitro manipulation.
Solar radio astronomy and space weather Radioastronomie solaire et météorologie de l’espace

The solar corona and its activity induce disturbances that may affect the space environment of the Earth. Noticeable disturbances come from coronal mass ejections (CMEs), which are large-scale ejections of plasma and magnetic fields from the solar corona, and solar energetic particles (SEPs). These particles are accelerated during the explosive variation of the coronal magnetic field or at the shock wave driven by a fast CME. In this contribution we will attempt to illustrate three aspects where radio observations can be important for space weather purposes: Radio emission as (1) a space weather hazard, (2) a tool to estimate CME speeds, (3) a tool to predict SEP events. Résumé: La couronne solaire et son activité engendrent des perturbations susceptibles d’affecter l’environnement spatial de la Terre. Les perturbations les plus énergétiques proviennent des éjections coronales de masse, qui sont des éjections à grande échelle de plasma avec le champ magnétique qui le confine, et des particules chargées de haute énergie. Ces particules sont accélérées au cours de l’évolution explosive du champ magnétique de la couronne ou aux ondes de choc engendrées par les éjections de masse rapides. Dans cette contribution, nous tenterons d’illustrer trois aspects où des observations radio peuvent être importantes pour la météorologie de l’espace: l’émission radio en tant que (1) source de perturbations, (2) outil de prévision pour estimer la vitesse des éjections de masse et (3) pour prévoir des événements à particules à la Terre.
DYNAMIC RESPONSE ANALYSIS OF MICRO-GRID WITH OCEAN THERMAL ENERGY CONVERSION

The main purpose of this paper is to analyze the dynamic responses of micro-grid with Ocean Thermal Energy Conversion (OTEC) system. The power sources of the studied micro-grid system include an OTEC generator and a wind generator. Three different types of OTEC generation systems, i.e., open-cycle, closed-cycle, and hybrid-cycle, are considered, under the conditions with the same temperature of sea water and output of generator. When the system operates in an islanding or gridconnected mode, the responses subject to load variation are quite different. As the system operates in the grid-connected mode, the voltage and frequency are less affected by the load changes; while the system operates under the islanding mode, affected voltage and frequency can be regulated by the exciter and the governor respectively and will return to a new stable state. According to the results, it is shown that the OTEC system can be regarded as a steady and reliable power supply in the micro-grid.
Global Epidemiology and Management of Acute Diarrhea in Children from Developing Countries

Diarrheal disease remains one of the leading causes of death in children under the age of five years in developing countries. Extensive measures have been in effect in low-and middle-income countries (LMICs), worldwide, to provide clean water, good hygiene, and sanitary living conditions. However, many survivors continue to deal with persistent diarrhea and nutrient deficiencies, affecting their growth due to their low socioeconomic status. There are over 2.5 billion diarrheal illnesses cases annually, which account for an estimated 1,400 deaths daily, according to the World Health Organization (WHO). The lack of maternal education, insufficiency or early cessation of breastfeeding, poor handwashing technique, improper storage of food and water, and limited access to proper health facilities in developing countries has resulted in children facing severe dehydration and prolonged mucosal injury that ultimately results in their death. For the patients that can access healthcare, diagnosis is achieved by stool microscopy and culture. Furthermore, polymerase chain reaction (PCR), has been used to test for Escherichia coli and norovirus to detect toxin-encoding genes, while enzyme immunoassay is used to detect other pathogens, such as Campylobacter, rotavirus, adenovirus, astrovirus, Entamoeba histolytica, Shigella, Giardia, and Cryptosporidium. Additionally, subsequent septic bacterial infections that result from inadequate care and poor management of diarrheal illness have resulted in the use of oral rehydration and antibiotics with a minimal resolution of persistent diarrhea in some patients. Several interventions that are being implemented in LMICs to combat diarrhea-related mortality, include providing educational resources to caregivers and healthcare providers, training caregivers to be able to detect early signs of deterioration in children, as well as purifying water and sanitation. Additionally, the importance of highly nutritious foods and proper breastfeeding techniques for the first six months of life have been shown to provide children with stronger immune systems to enable them to combat infections.

Non-LTE line formation for neutral oxygen

An extensive model atom for non-LTE line formation calculations for O I is presented, taking into account recent improvements in the atomic data. Based on line-blanketed LTE model atmospheres equivalent widths are computed in LTE and non-LTE for the diagnostic O I lines of Aand late B-type stars in the range Teff = 7500 K to 15000 K and luminosity classes V to Ia. Non-LTE abundance corrections are provided: they span a wide range in magnitude, from less than 0.1 dex for the weak lines in main sequence stars to more than 1.5 dex for the near-infrared lines in some supergiants. The dependence of the non-LTE effects on the atmospheric parameters is discussed with special emphasis on supergiants. In particular, the near-infrared transitions are found to react sensitively to the collisional excitation cross sections used in the calculations. Further investigations concentrate on the influence of microturbulence and on the rôle of wind outflow velocity fields on the line formation. As a test and first application of the model, oxygen abundances for Vega (A0 V), η Leo (A0 Ib) and HD 92207 (A0 Iae) are derived. The analysis of Vega confirms a slight oxygen underabundance (∼0.3 dex) in this star while η Leo and HD 92207 show a nearly solar value. For Vega the observed spectrum can be reproduced accurately by the calculated line profiles. In supergiants consistent abundances can be derived from the weak lines in the visible. At high luminosities the prominent near-infrared features – among other strong lines from different elemental species – are subject to additional broadening by an unidentified process which prevents an equally accurate theoretical interpretation.
The Effect of E-Human Resource Management (E-HRM) on Cost Efficiency and Productivity of Employees in the Company

— Human Resource Management (HRM) transforms by using information technology to improve its performance, to carry out the transformation of investment issued by the company, so the most important question arises whether the investment made has benefits to the company. This study aims to determine the effect of the implementation of E-HRM activities such as, E-Recruitment, E-Compensation, E-Training, and E-Performance Appraisal, which have the most positive and significant impact on employee productivity and cost efficiency in the company. This research is a quantitative study, using the SEM-PLS method. The population in this study is PT. Pertamina (Persero). The sample in this study was the Directorate of Humen Capital, with the sampling technique used was purposive sampling. Based on the results of testing using SEM-PLS shows that the E-Compensation and E-Performance Appraisal variables have a positive and significant impact on Cost Efficiency. E-Training Variables have a significant influence on Employee Productivity. Meanwhile, the E-Recruitment variable does not have a significant effect on Cost Efficiency and Employee Productivity
Spontaneous Rehydroxylation of a Dehydroxylated Cis-Vacant Montmorillonite

In general, montmorillonite and other dioctahedral 2:1 layer silicates are characterized by dehydroxylation temperatures between 500–700°C ( e.g., Mackenzie, 1957; Grim and Kulbicki, 1961; Schultz, 1969; Guggenheim, 1990). Differences in dehydroxylation temperature are primarily related to the kind of octahedrally coordinated cations present and their distribution and movement in dioctahedral 2:1 layer silicates (Drits et al., 1995), although the interlayer cation may have an effect also ( e.g., Guggenheim and Koster van Groos, 1992). Trans -vacant (tv) smectites and micas are characterized by dehydroxylation temperatures which are 150–200°C lower than those for the same minerals consisting of cis -vacant (cv) 2:1 layers. Most montmorillonites consist of a mixture of cv and tv 2:1 layers and lose their hydroxyls in two steps near ~550 and ~700°C (Drits et al., 1995). Hence, the investigation of the structure of dehydroxylated montmorillonite is of great interest to understand the dehydroxylation process ( e.g., Jonas, 1954; Heller et al., 1962; Drits et al., 1995). Dioctahedral 2:1 layer silicates are expected to produce well defined dehydroxylates after heating for a short time at temperatures between 500–700°C and cooling under laboratory atmosphere ( e.g., Grim and Bradley, 1948; Heller-Kallai and Rozenson, 1980; Drits et al., 1995). However, the heating rate (Hamilton, 1971) and duration of heating (Horvath, 1985) are important in determining if an anhydrous state is achieved. A slow heating rate lowers the apparent dehydroxylation temperature, which is a well known but often neglected phenomenon. Emmerich et al. (1999) found that a completely dehydroxylated state of montmorillonites that …
A facile general strategy for synthesis of palladium-based bimetallic alloyed nanodendrites with enhanced electrocatalytic performance for methanol and ethylene glycol oxidation

In this work, a facile general strategy is developed for preparation of palladium-based bimetallic alloyed nanodendrites (PdM NDs, M = Pt, Co, and Ni) via coreduction of Pd(II) acetylacetonate and M(II/III) acetylacetonate salts with oleylamine. Hexadecylpyridinium chloride monohydrate (HDPC) is used as a co-surfactant for preventing the aggregation of nanodendrites. Control experiments varying the precursors and reaction time demonstrate that the dendritic nanocrystals are formed via aggregation-based crystal growth. The as-prepared hybrid nanocrystals display improved electrocatalytic activity and better stability for methanol and ethylene glycol (EG) oxidation, compared with home-made Pd NDs and commercial Pd black catalysts. The developed method provides a novel platform for synthesis of novel electrocatalysts in fuel cells.
Large-Scale Provenance for Soufflé

Logic programming languages, such as Datalog, have seen a rise in popularity in recent years, now being widely used to answer questions about real world problems. This popularity stems from the wide applicability of logic as a domain specific language for a variety of problems including static program analysis, declarative networking and security analysis. The use of logic reduces the complexity of implementing applications as programs are written in a declarative fashion. In other words, instead of describing computational steps imperatively, computations are concisely specified by their intended result. As a consequence, however, the lack of computational steps makes debugging very challenging, and there is no clear debugging strategy in logic programming. In the field of database research, provenance has been introduced as a way of explaining the output of relations, and can also be applied to Datalog. The big challenge with large real-world problems, however, is that the relations may contain billions of tuples, rendering existing provenance approaches infeasible. Hence, there is still a gap to design and implement scalable and reusable provenance systems for high-performance open-source Datalog engines, such as Soufflé. In this thesis, we develop the theory of provenance in the form of a proof tree for a given tuple. However, the construction of the proof tree in a naïve fashion is too expensive for large datasets. To ensure scalability, we push computation from logic evaluation time to proof construction time, achieving an efficient space/time trade-off. This lazy evaluation approach produces an annotated intensional database, which can be queried after evaluation by an arbitrary number of provenance queries without the need for recomputing the intensional database. We conduct experiments with complex industrialstrength benchmarks, including DOOP with DaCapo, which produce hundreds of millions of output tuples. We demonstrate that our novel provenance approach incurs a runtime and memory consumption overhead of 1.5× on average. Thus, it can cope with large datasets, where existing techniques and a naïve implementation become infeasible.
Establishing valid measures of children’s adjustment to the first year of schooling

The absence of, or difficulty with, social or cognitive skills, and the presence of problem behaviours generally impacts on a child’s adjustment to school and is seen to indicate maladjustment (Thompson, 1975; Gresham & Elliott, 1987; Ladd & Price, 1987). The identification of the skills and behaviours that predict children’s adjustment to the first year of schooling can assist early childhood staff in identifying children at risk of maladjustment, and in the implementation of appropriate intervention strategies. This report will explore work-inprogress involving confirmatory factor analysis and structural equation modelling using LISREL to identify items that contribute to constructs of children’s adjustment to the first year of schooling and to identify the relative contribution of each of these items to the adjustment subdomains of social skills, problem behaviours and academic competence involving data obtained using the Social Skills Rating System (Gresham & Elliott, 1990).
Lithium‐Air Batteries: Survey on the Current Status and Perspectives Towards Automotive Applications from a Battery Industry Standpoint

Li‐air rechargeable batteries theoretically have advantages from both secondary batteries and fuel cells, which can be viewed as the best technological blends for automotive applications resolving the so called mileage anxiety problem due to the limited driving range of electrical vehicles based upon Li‐ion batteries; this problem is rooted in the intrinsically small energy density of Li‐ion batteries. This very scientific trait of Li‐air batteries, which is apparently suited to the requirements of batteries for future electric vehicles, has induced quite a strong surge of research recently. This occurrence has motivated the authors to undertake a thorough review in an effort to understand the current status of Li‐air battery related technologies. A comprehensive survey from a battery industry standpoint has been conducted on the fundamentals of chemistry, utilized Li‐air cell configurations (or types) vs. performance, and major components comprising Li‐air batteries using various sources of previously published peer‐reviewed journal papers, book chapters, patents, and industrial reports. The survey results are presented here.
Investment location selection: Strategies for foreign direct investment in Vietnam

Foreign direct investment distribution is unequal in terms of economic activities as well as among regions, provinces and cities within countries. Therefore, understanding reasons why foreign investors favour a location over others are necessary for policymakers, governments, and international investors. Although determinants of selecting investment locations have been studied, different determinants are identified in different countries. Additionally, studies on the investment location selection within a country are limited, especially in Vietnam. This gives rise to questions which factors make a location more attractive to the foreign investors and whether they have similar effects in different provinces and cities within a country. This paper aims to investigate the determinants of investment location selection at the provincial level in Vietnam based on foreign investors’ perspectives. The four groups of factors include human capital, economic, provincial competition and institutional, and infrastructure. The study uses panel data set with 63 Vietnam provinces and cities from 2000 to 2015. The ordinary least squares estimation supported by the Hausman test is employed in the empirical estimation. The results of models with and without a lag term are robust. Unlike many previous studies, we employs retail sales of goods and services instead of gross domestic product to represent economic growth at the provincial level. The provincial competitiveness index is employed to represent economic governance of provinces and cities. The investment incentive policies index is proposed as the aggregate index of three types of investment incentives (free land, income tax exemption, and import tax exemption) instead of considering only tax incentives. The country risk index is proposed to represent the political stability and security. Ranking of provinces and cities based on their socio-economic conditions is employed to investigate the different effects of the determinants in different areas in Vietnam. Surprisingly, this study shows that foreign investors tend to invest more in areas with fewer investment incentives. Additionally, foreign direct investment flows into Vietnam increased after the financial crisis in 2008 as foreign investors may take advantage of lower value currency and lower cost in the areas offering high investment incentives. The effect of infrastructure development on investment location selection is weaker in areas under more difficult socio-economic conditions. This study suggest that Vietnamese policymakers and provincial governments should invest more in education and training, control exchange rate and inflation rate, enhance investment efficiency, maintain political stability and security, improve infrastructure to boost economic growth, and improve economic governance in addition to offering more investment incentives.
Network Effects on Migrants’ Labor Market Outcomes in China

This paper uses 2005 China’s mini-census to study how networks affect migrants’ migration decisions, employment, and wage levels. Different from existing studies, this paper takes into account the existence of self-selection in the labor market. With the help of theoretical model, we have a better understanding of the mechanism of networks as well as the different network effects on rural and urban migrants. We find out that networks affect both rural and urban migrants’ migration decisions positively. In terms of employment, networks exert positive impacts on rural migrants but not on urban ones, which is due to the different quality drops between rural and urban migrants when the networks increase. Such employment effects also lead rural migrants to face a more severe negative wage impact than urban migrants.
Transform-Aware Content Adaptive Stegosystem for Social Networks

—The aim of steganography is to hide information in the other data, such as images. Nowadays, the most common channels for sharing images are social networks and it makes them perfect for steganography. Usually they scale and recompress uploaded images for storage saving. Unfortunately, most of contemporary stegosystems are very fragile to any image modiﬁcation, which limits their application in this case. In this paper we propose the system able to transfer information through such channels. It outperforms error correction code based approaches in terms of capacity and distortion since it takes into account the speciﬁc transform. We implemented the ﬁrst steganographic algorithm able to restore the message after JPEG recompression in social networks without errors and successfully veriﬁed it in real world with Twitter.
Linear High Molar Mass Polyglycidol and its Direct α-Azido Functionalization

Summary: Linear polyglycidols with narrow chain dispersity and controlled high molar masses were prepared in a few hours by monomer-activated anionic polymerization of protected monomers, ethoxyethyl glycidyl ether and tert-butyl glycidyl ether, using a system composed of tetraoctylammonium bromide as initiator and triisobutylaluminum, used in 1.5 to 5-fold excess compared to the initiator, as co-initiator and monomer activator. This synthetic approach was shown to give various polyglycidol-based copolyethers in particular with propylene oxide or butene oxide. α-Azido,ω-hydroxy-poly(ethoxyethyl glycidyl ether) and other polyethers were directly prepared when tetrabutylammonium azide was used as initiator. Size exclusion chromatography and matrix-assisted laser desorption/ionization time-of-flight characterizations as well as “click” reactions were used to demonstrate the efficiency of the functionalization.
