    The separation process of mineral glass lid on SME (UKM) partner still use manuallly method, it uses a razor blade. The purpose of this program (PKM – T) is to improve efficiency and effectiveness in separating process so that its productivity can be increased. This machine has easy operation, by pressing ON if it is being used and pressing OFF after using it. The method offered by our team to solve the problems uses several stages. Formulating the problems then create the machine, trial and repair it, training and maintenance it. The last is acceptance and monitoring. Based on the activities that have been done on schedule, our team can create separator machine with capacity 25 kg/h. It is quite practical and efficient to operate. The conclusion is the capacity of separation process 50 kg/ h by using this machine or increase from the previous capacity using conventional method, 25 kg/h. It means it will increase the price of the mineral glass and reduce the energy used for separation process

    Synthesis of novel structural hybrids between aza-heterocycles and azelaic acid moiety with a specific activity on osteosarcoma cells

    Nine compounds bearing pyridinyl (or piperidinyl, benzimidazolyl, benzotriazolyl) groups bound to an azelayl moiety through an amide bond were synthesized. The structural analogy with some histone deacetylase inhibitors inspired their syntheses, seeking new selective histone deacetylase inhibitors (HDACi). The azelayl moiety recalls part of 9-hydroxystearic acid, a cellular lipid showing antiproliferative activity toward cancer cells with HDAC as a molecular target. Azelayl derivatives bound to a benzothiazolyl moiety further proved to be active as HDACi. The novel compounds were tested on a panel of both normal and tumor cell lines. Non-specific induction of cytotoxicity was observed in the normal cell line, while three of them induced a biological effect only on the osteosarcoma (U2OS) cell line. One of them induced a change in nuclear shape and size. Cell-cycle alterations are associated with post-transcriptional modification of both H2/H3 and H4 histones. In line with recent studies, revealing unexpected HDAC7 function in osteoclasts, molecular docking studies on the active molecules predicted their proneness to interact with HDAC7. By reducing side effects associated with the action of the first-generation inhibitors, the herein reported compounds, thus, sound promising as selective HDACi

    One Germany, Two Worlds of Housework? Examining Single and Partnered Women in the Decade after Unification

    Despite much recent changes in gender relations, housework remains an area where women bear primary responsibility. This paper examines the role of policy and employment context on housework, not only for women who live with partners, but also for single women. I study German women's housework in the decade after unification, which allows me to simultaneously assess the impact of the ideological legacies of the FRG and the GDR, while also studying the role of different levels of labor market participation. I find that women with partners do more housework than singles, and that part-time employees do more housework than those working full-time. The results show no regional differences in singles' housework performance. However, among women with partners, West German women do significantly more housework. The analyses reveal that differences in the housework levels of full-time and part-time workers can be explained by the differences in mechanisms for the two groups. Full-time workers reduce their housework in response to their paid labor involvement to a lesser extent than part-time workers, in particular in East Germany, where women's full-time employment has long been normative

    What Makes Russian Women (Un)Happy? A Closer Look at the Family

    Two decades of economic transition revealed that Russian women are on average less happy than men. This paper addresses individual subjective well-being from the intra-family perspective and investigates whether the gender satisfaction gap could be caused, among all, by a mismatch between the socially imposed patriarchal family gender roles and the actually performed ones. I test for the presence of the following phenomena: (1) a fair share of income brought by each of the spouses into their household is judged according to the patriarchal model attributing the role of the breadwinner to men; (2) division of housework, with women, even if working, holding the main responsibility for housekeeping activities, is perceived as fair. Prime-age working adults living in partnership constitute the dataset which is a part of the Russian Longitudinal Monitoring Survey for 1994-2004. Life satisfaction is modelled with the help of the seemingly unrelated bivariate ordered probit model aiming at the adjustment for unobserved factors influencing happiness evaluation of both partners. For the period 1994-1998, the results show that women's relative unhappiness is likely to be causes by their increasing earning powers with relative to men, and overload with hours spent on housekeeping in households with children. In the second period of economic growth, 2000 - 2004, I observe a change in women's preferences over time-use and total income shares, suggesting a tendency towards their emancipation

    Are Women Happier When Their Spouse is Teleworker?

    © 2017 Springer Science+Business Media Dordrecht. This study explores the household production allocation and happiness of women when their spouse is teleworker using data from the British Household Panel Survey over the years 1991–2009. The study aims to answer whether the women spend additional time on housework and are happier when they or their partner is teleworker. Also, we explore whether are happier when they share the household–domestic production with their partners. Fixed effects estimates take place, and we consider a Bayesian Network framework and a directed acyclic graph for causal inference. The results show that women are more likely to state that the household allocation, such as cooking, cleaning, ironing and childcare is shared when their partner teleworks. Shopping is an exception which can be regarded as an outdoor activity while one partner may be mainly responsible for this chore. In addition, women are happier when they or their spouse is teleworker, and they report higher levels of happiness when the household production allocation is a shared process. This may indicate men teleworkers may contribute extra to the household production releasing a burden for the partners and improving their well-being
