Abstract:Although, superovulation is widely used for obtaining maximum number of oocytes from a female, but inconsistent superovulatory response is a great challenge since last few decades and may be related to the gonadotropinâ€™s type and more precisely to the timing of gonadotropin treatment. In current study, we evaluated the superovulatory response with respect to stage of estrous cycle in BALB/c mice treated with commonly used gonadotropins (FSH or eCG). Mice were first screened for stage of estrous cycle through vaginal cytology and then treated with either FSH (Four doses, 2.5 IU per does; SC,) or eCG (Single dose, 5 IU; IP). Total number of oocyte/cleaved embryos (36 hours post hCG) and somites (9.5 dpc) were compared for all stages of estrous cycle against both treatment groups (FSH or eCG). The results revealed that stage of estrous cycle did not affect the total number of recovered oocytes and cleaved embryos in FSH-treated mice (P > 0.05). However, in eCG-treated group higher (P < 0.05) number of oocytes and embryos were recovered at proestrus and estrus stages, while numbers of cleaved embryos were higher (P < 0.05) at proestrus. Furthermore, no significant difference was observed in embryo quality regarding number of somites at any stage of estrous cycle in both gonadotropin groups. Further, the supervoulatory response in BALB/c mice was comparatively better in eCG group than FSH. These findings indicate that superovulatory response in eCG treatment is stage dependent. While, FSH can be injected at any time as superovulatory response was independent of stage of estrous cycle.
Abstract:_In the context of the increasing level of globalization, one of the main challenges for the economies of the countries is to increase competitiveness through innovative development. Innovative development is in constant dynamics of change. That is why the main task in conducting the incentive policy is to constantly analyze the disadvantages of the functioning mechanism of state regulation and to find ways to improve its effectiveness.\nIdentification of problems and disadvantages of the modern mechanism of state regulation of innovative development of Ukrainian economy.\nWe evaluated the use of mechanism of state regulation tools, namely: regulatory, administrative, financial, motivated, informational and organizational. We also determined the index of the current economic condition, the intensity of structural changes in the number of industrial enterprises and the intensity of structural changes in the total amount of budget financing for innovative activities in 2013–2017. A statistical evaluation of the results of the studied indices was determined using the Salai and Gatev coefficients.\nThe state of innovative development of the Ukrainian economy is investigated, problems and disadvantages of the modern mechanism of state regulation of innovative development are revealed. The assessment of the use of instruments of the mechanism of state regulation of innovative development of the economy for regulation of spheres providing innovative development of the economy. The state of innovative infrastructure is analyzed, the state of the socio-economic environment of the country is estimated using the index of current economic capacity. The scale of structural shifts was quantified using the integral coefficient of structural changes of A. Salai and the integral coefficient of structural differences of K. Gatiev. Factors of influence on innovative economic development and structural changes of industrial-innovative enterprises are determined. Recommendations for solving existing problems of innovative economic development are given.\nThus,we identifinedsuch problems as low level of communication between the entities of the mechanism of state regulation of innovative development, problem of effective use of the tool, low infrastructural support, failure to observe the basic principles of state regulation, poor quality and environmental status of state regulation of innovative development, lack of monitoring.
Abstract:The views of the people in the Ogan Ilir region towards the Simbur Cahaya Law are very positive, because the law makes the community more orderly, besides that this law contains very supportive rules, and holds the moral values that are in line with the teachings of Islamic law. The existence of this law is unity in applying the law, especially as it relates to the association of Single bachelors. The behavior and association of Single bachelors in current conditions may be said to have deviated significantly from applicable legal provisions, both state and Islamic law. The Simbur Cahaya Law is a historical result; for this reason, the existence of the Simbur Cahaya Law can be a future reference for protecting and regulating behavior towards bachelor girls and applying severe sanctions for those who commit sexual harassment.
Abstract:The article considers the technology of enterprise potential management in the coordinate system of organizational development. The built model of organizational support requires consideration of factors that are common to all its components. In particular, when making local decisions in the centres of responsibility associated with a particular component of the system. Organizational development of the enterprise is largely associated with the phase of the life cycle of the enterprise. Each of the components of the system of sets of organizational support for the rationalization of the potential of the enterprise is active throughout the life cycle of the enterprise. But the onset of the final phase of development is a sign of the absence or weakness of the mechanism built at the enterprise for the development of creative initiatives in the management of enterprise potential. It is substantiated that the parameters of the model of organizational support of rational realization of enterprise potential require quantitative parameterization, especially for making informed decisions related to capacity management by phases of the enterprise life cycle.
Abstract:This investigation analyzed the impact of changes in water quality, emphasizing the importance not only to describe the causes of these changes but also the effects it has on ecosystems and the population present in the area of influence. The contamination of water sources and the ensuing changes in the physical and chemical conditions of the water are considered to be a cumulative impact because, over time, it triggers other effects on the health of ecosystems and people. The environmental impacts associated with water quality were identified and evaluated with the methodology proposed by Conesa (2010), and changes in habitat together with the impact on aquatic ecosystems and ecological flow were determined to be the major agents of change. By contrast, the least significant impacts were noise generation, emission of particulate matter, and slope instability. Extractive mining, followed by agricultural, livestock, and industrial activities generated the greatest impact on the environment. However, the difference found was only of one point on the rating scale, and all of these activities were classified as moderate. Analysis of actions that generate impact determined that the most important one, on average, is inadequate use of the soil, followed by the generation of dump sites. Estimation of the environmental impact associated with the water quality of the Bogotï¿½ River underscored that changes in water quality were classified as a critical impact. Among those areas severely impacted were alteration of landscape, wetland system, and the populationï¿½s health. Among those with the lowest scores were noise generation, gas emissions, and odors. A software tool was designed to validate the methodology developed for analysis of said environmental impact associated with the water quality of the Bogotï¿½ River.

Abstract:It’s often found in the internet that the cryptosystem can be divided into two parts, symmetric encryption system and asymmetric encryption system. The key which is used in the cryptosystem is a fixed set recently, but there are deficiencies in security. If someone try to crack the code, it is easy to make the key unsafe after a long time that resulting in the secret information leakage. The experiment was carried out using Matlab mathematics software by elliptic curve cryptography, and, tested through ZigBee facilities of the wireless transmission systems. The original used key can change automatically in server, and produces lots of sets at once in this paper. Therefore, the cryptosystem can be used for long. When we transmit the information every time, the changing key will increase the difficulties that may be cracked every time. We can increase the safety and do not increase the extra computed complexities.
Abstract:This study primarily used the Taguchi test production parameters to analyze the correlation between the commercial application properties (compressive strength, volatile components and calorific value) of environmentally friendly fuel derived from wood chip gasification carbon black and the production conditions (adhesive, molding temperature and molding pressure),then, the optimal application conditions are sought.\n The results showed that the optimal production conditions were the addition of 4% PVA-1000 adhesive and the production of derivative fuels with current commercial product specifications at a molding temperature of 151 ° C and a molding pressure of 132 kg/cm2.
Abstract:This paper presents a ZMP calculation method based on internal stress to handle the balance of a class of biped robots. Considering foot-ground contact environment complexly caused zero-moment point (ZMP) error too large during the walking process of the biped robot, a ZMP ideal calculation model has been developed, then the axial stress and shear stress on the vertical section of the sole material is utilized to reconstruct internal stress biped robot ZMP calculation formula, and in order to verify for the errors produced by the new calculation formula, four different ground-crash simulation experiments has been designed and compared. Based on the evolution of the ZMP trajectories, the internal-stress ZMP calculation method can effectively predict the ZMP position of biped robot under natural walking without torque sensor. With the experimental value is compared with the actual value, the average distance error is minimum between the actual and the experimental value at the foot height 20mm has been proved theoretically. We have conducted experimental studies on a biped robot to demonstrate the effectiveness of the proposed calculation method.
