Two principally different mating systems are practised for farmed silver foxes. In the traditional system the breeding females are kept all the time in cages well separated from each other. In the Nordic system, on the other hand, the breeding females are transferred prior to mating time into a separate shed where they are placed close to each other and sometimes males are put among them. After artificial insemination (AI) or natural matings, the females are transferred in the mating order to new cages. The condensed premating grouping is assumed to enhance the effect of air-borne male and female pheromones leading to a more intense and synchronised heat development. In this study these two systems were compared for timing and synchrony of parturitions. In contrast to the working hypothesis, date of whelpings were positively skewed with a great kurtosis in the traditional system, an indication that the majority of deliveries occurred during a short period and at the beginning of the season. On the other hand, in the Nordic system the whelpings were more uniformly distributed over the whole season and the peak was later. The results show that the most recent system, although widely used, is not necessarily the only possible alternative but other alternatives should also be considered. ;

This study discusses about language use occurred by male and female host in Hitam Putih talk show. The method of this research is descriptive qualitative. The subjects of this study are male and female host in Hitam Putih talk show. The data are the utterances produced by male and female host in Hitam Putih talk show. This research focuses on the show broadcasted on October 2016 by taking 4 videos randomly. The objective of this study is to describe kinds of the language use uttered by male and female host in Hitam Putih talk show. The findings showed that the kinds of language use consist of 6 parts. The dominant language use uttered by male host is expletive, because male’s utterances are frequently stated in a negative connotation. On the other hand, female host utterances are found in specialized vocabulary as the most dominant because female host has more interest in talking family affairs, such as the education of children, clothes, cooking, and fashion, etc. Women also tended to talk about one thing related to the home and domestic activities. However, the representation of language use uttered by male and female are deficit, dominance and different. Keywords: Language Use, Gender, Talk Show

One of the causes of low reproductive efficiency in dairy cattle is the presence of reproductive disorders caused by a non-specific bacterial infection. The aim of the present study was to isolate and identify the genus of non-specific bacteria in the reproductive tract of dairy cattle during artificial insemination. A total of 10 samples in the form of mucus attached to the plastic sheath used after artificial insemination in dairy cattle were collected in the study. The samples were subjected to bacterial isolation and identification. The obtained results of the study indicated that Staphylococcus was the dominant genus found (90%). On the other hand, other genera were Escherichia (60%) and Corynebacterium (20%).

Background: Fluoride protects the teeth from dental caries using the needed amount of fluoride products.Methods: A Modified structured questionnaire has been validated through a pilot trial (20 responses) prior to administration that contains16 questions was distributed. Other than the demographics, the data were collected from 500 participants including undergraduate male and female dental students.Results: The majority described the mild fluorosis appearance in the teeth according to Dean’s index appropriately as white opacity of the enamel (64%, n=320). On the other hand, only 31.1% (n=155) and 46% (n=229) described the moderate and severe fluorosis appearance in the teeth according to Dean’s index appropriately.Conclusions: The dissemination and education about dental fluorosis is urgently needed and should be tailored to reach this population. The knowledge about causes of fluoride and the effect on dental fluorosis should be presented in the education.

Abstract As there have been many researches for bolt self-loosening and a lot of knowledge have been accumulated, the phenomena has been understood more and more clearly. On the other hand, it is quite difficult to achieve both non-self-loosening and easy bolting tasks. In practical situations, easy and stable bolting is more focused and torque control is employed for tension control in the fields. For the stable bolting, friction of the threads is reduced by lubrication. However, the effect of this friction reduction is not yet investigated in the aspect of self-loosening. In this paper, the effect of frictions between male and female threads and between nut and bearing surface is investigated by FEA simulations. This provides information how self-loosening can be controlled. In this paper, the motion of the fastened plate transverse to the bolt axis is considered. This motion is known as the easiest motion to make self-loosening in experience and also as shown so in the author’s previous researches. The friction seems to increase self-loosening and also decrease self-loosening at the same time. It seems that the friction on the bearing surface drives self-loosening and friction on the thread surfaces prevents it. In this paper, both the frictions are examined in the relative manner with the Finite Element Analyses.

The bathymetry of nearshore coastal environments and lakes is constantly reworking because of the change in the patterns of energy dispersal and related sediment transport pathways. Therefore, updated and accurate bathymetric models are a crucial component in providing necessary information for scientific, managerial, and geographical studies. Recent advances in satellite technology revolutionized the acquisition of bathymetric profiles, offering new vistas in mapping. This contribution analyzed the suitability of Sentinel-2 and Landsat-8 images for bathymetric mapping of coastal and lake environments. The bathymetric algorithm was developed using an empirical approach and a random forest (RF) model based on the available high-resolution LiDAR bathymetric data for Mobile Bay, Tampa Bay, and Lake Huron regions obtained from the National Oceanic and Atmospheric Administration (NOAA) National Geophysical Data Center (NGDC). Our results demonstrate that the satellite-derived bathymetry is efficient for retrieving depths up to 10 m for coastal regions and up to 30 m for the lake environment. While using the empirical approach, the root-mean-square error (RMSE) varied between 1.99 m and 4.74 m for the three regions. The RF model, on the other hand, provided an improved bathymetric model with RMSE between 1.13 m and 1.95 m. The comparative assessment suggests that Sentinel-2 has a slight edge over Landsat-8 images while employing the empirical approach. On the other hand, the RF model shows that Landsat-8 retrieves a better bathymetric model than Sentinel-2. Our work demonstrated that the freely available Sentinel-2 and Landsat-8 imageries proved to be reliable data for acquiring updated bathymetric information for large areas in a short period.

We present VLBA observations of the spatial and velocity distributions of 22 GHz H2O and 1612 MHz OH masers in the OH/IR star W 43A. These masers have the same systemic velocity and are, therefore, likely to be associated with the common stellar object. However, the kinematical structures of them are quite different and independent. Most of the H2O masers are extremely collimated spatially and kinematically. The H2O maser jet also seems to be precessing. On the other hand, the OH masers exhibit clear arc-shaped structures indicating a spherically-expanding shell with weak collimation. The W 43A jet is very likely to be predominantly composed of hot molecules traced by H2O maser emission and formed in the immediate vicinity of an unknown star next to another OH/IR star. Such a “molecular jet” is likely to appear only during the short period before a star forms an elongated planetary nebula.

This study compares degree of homophobia between social work and non-social work students. The results show that although social work students are not significantly different from non-social work students in their levels of homophobia, both male and female social work students are significantly less homophobic than male non-social work students. On the other hand, somewhat surprisingly, female social work students are significantly more homophobic than female non-social work students on the issues of whether homosexuality is a sin and whether homosexuality is disgusting. Implications for social work education are discussed.

SummaryThis study compares the incidence of a variety of cutaneous conditions among 91 patients treated with lithium carbonate with the incidence of such conditions among 44 patients treated with other non-neuroleptic, maintenance medications. Data on cutaneous conditions and allergies were obtained using structured interviews, demographic data, medication histories and personal and family histories.A significantly greater proportion of the lithium-treated patients than the comparison patients reported a cutaneous condition which may have been secondary to treatment in that it developed for the first time after the medication or appeared to have been exacerbated by the medication. Among the lithium-treated patients, females were found to be significantly more likely to report a secondary cutaneous condition. This effect was found across the whole range of cutaneous conditions. Male lithium-treated patients on the other hand reported approximately the same rate of secondary cutaneous conditions as both male and female comparison patients. Possible reasons for this sexual effect on incidence are discussed.The literature on cutaneous conditions which have been associated with lithium therapy is also reviewed.

ABSTRACT There is a big difference between male and female in the rural environment of Bangladesh and the aim of this eating habits and nutritional status. The study was conducted through 384 respondents from 9 villages in Ishwardi, Pabna; a north-western district of Bangladesh. The research has done on the food habits of the middle and lower class people of the villages. And some informations are collected from the different sources. In the research 73.44% of male earn more than 24 thousand BDT per month when only 43.32% female are earning more than 24 thousand BDT. Most of the female are housewives and male are service holder. 44.79% male  are service holder on the other hand 4.69% female are service holder. Rice is the main food for Bangladesh. So, most of the people have rice on daily three times. 37.80% of female and 66.98% of male are having rice. Ruti is the second priority food, female take this food 0.56% and male take 7.55% for 2 days. 63.33% female take egg, on the other hand 58.07% male take egg per week.  3.2% female her meal last of all and 1.5% female take it first of all. On the other hand 6.25% male take their meal first of all and 3.39% male take their meal last of all. Most of the female are normal having BMI 89.06% on the other hand male are overweight 78.18%. In the light of the study the eating habits of male and female in Bangladesh have improved but it has not yet affected everyone.

Some people still cannot talk freely about sex education. On the other hand, some of them have an assumption about teaching sex education will leads to free sex behavior. Sometimes parent afraid to talk about sex education with their children, even some parent think sex education is not important thing for children.However, in fact children need to know about sex education for their own good. To children, sex education is to explain differences in male and female and to know well about themselves. Create media to deliver sex education is the way to teach children about sex education. Among many media, game is one option to deliver this education.This research will discuss about game for childs sex media education. Use game as sex media education because game has capability to deliver message. Through game concept, picture, and animation, game deliver childs sex education to children. With the objective to prevent child from sexual abuse. However, when children play the game they need companion to make clear that children understand the meaning of game message through game story.
