Photoinduced catalytic halopyridylation of alkenes

This study aims to investigate employee safety behaviour by relating it to safety leadership, safety communication, safety commitment, and safety climate. This research was conducted at PT GMF AeroAsia Tbk in the Cengkareng home base, and multibase areas of Kalimantan, Bali & Nusa Tenggara, Sumatra, Sulawesi & East, and Java. The study began in early September 2019 until the end of March 2020, using a quantitative and explanatory design approach through testing hypotheses to examine the nature of relationships and influences between variables. The population of 2,400 employees with a sample of 342 respondents. The sample distribution uses proportionate cluster random sampling. SMI-4a Model testing and data processing using Structural Equation Modelling (SEM). The data was then analysed using AMOS 22 statistical software. Work accidents at the largest MRO (Maintenance Repair and Overhaul) companies were mainly caused by safety behaviour. Test results from several variables of this study can help the managerial team make an effective approach to improve safety behaviour in the workplace.The purpose of multi-level contribution margin accounting in cost accounting is to analyze the profitability of products and organizational entities with appropriate allocation of fixed costs and to provide relevant information for short-term, medium- and longer-term decisions. However, the conventional framework of multi-level contribution margin accounting does not usually incorporate a mathematical optimization method that simultaneously integrates variable and fixed costs to determine the best possible product mix within hierarchically structured organizations. This may be surprising in that operations research provides an optimization model in the form of the fixed-charge problem (FCP) that takes into account not only variable costs but also fixed costs of the activities to be planned. This paper links the two approaches by expanding the FCP to a multi-level fixed-charge problem (MLFCP), which maps the hierarchical decomposition of fixed costs in accordance with multi-level contribution margin accountingt structure and other parameters is tested via sensitivity analyses and stochastic optimization.
Reported monthly scrub typhus (ST) cases in Thailand has an increase in the number of cases during 2009-2014. Humidity is a crucial climatic factor for the survival of chiggers, which is the disease vectors. The present study was to determine the role of humidity in ST occurrence in Thailand and its delayed effect.
We obtained the climate data from the Department of Meteorology, the disease data from Ministry of Public Health. Negative binomial regression combined with a distributed lag non-linear model (NB-DLNM) was employed to determine the non-linear effects of different types of humidity on the disease. This model controlled overdispersion and confounder, including seasonality, minimum temperature, and cumulative total rainwater.
The occurrence of the disease in the 6-year period showed the number of cases gradually increased summer season (Mid-February - Mid-May) and then reached a plateau during the rainy season (Mid-May - Mid-October) and then steep fall after the cold season (Mid-October - Mid-Fland, particularly at a high level and usually occurred within the past month. NB-DLNM had good controlled for the overdispersion and provided the precise estimated relative risk of non-linear associations. Results from this study contributed the evidence to support the Ministry of Public Health on warning system which might be useful for public health intervention and preparation in Thailand.[This corrects the article DOI 10.1016/j.heliyon.2019.e01848.].The study examined the outcomes of participatory fisheries management in Mweru- Luapula fishery in northern Zambia. The main objectives were to evaluate the performance of Village Fisheries Management Committees (VFMCs), analyze participation of fishers in management activities and to assess fishers' compliance to fisheries regulations. Data were collected through structured interviews with 64 respondents, five focus group discussions and two key semi-structured interviews. Ostrom's eight design principles and White's typology of Interests was employed to analyze VFMCs performance and fisher participation respectively. Descriptive statistics and content analysis were employed to analyze the quantitative and qualitative data respectively. Results show that inadequate financial support to the Department of Fisheries has culminated in the capture of benefits by VFMC positions by local elites, and ultimately weakened enforcement of fisheries regulation. A nominal form of participation characterizes the co-management as resource users are not engaged in decision making and power still resides with the Department of Fisheries. Low compliance to the seasonal fish ban by fishers due to inconsistent patrols by VFMCs and Department of Fisheries has resulted in persistence of illegal fishing practices that threaten conservation of fish in the fishery. The minor positive outcomes of co-management suggest its ineffectiveness in curbing illegal fishing activities. A common property regime where smaller groups of fishers exploit a portion of the fishery with locally designed operational rules is therefore recommended to replace the 'consultative' type of co-management prevailing in Mweru- Luapula fishery.On the rise request for long-lasting materials, clay materials are in between the well-nigh minerals exploited by production and ecological fields in the making of fired bricks. Clay incessantly expounded to high temperature reacts differently at ambient temperature which critically touches its longevity. In present study, a coupled thermo-mechanical damage model of clay is established. In this model, the Unified Strength Theory (UST) criterion is used as the failure criterion based on the Weibull distribution and the continuous damage theory. The proposed model is validated by uniaxial compression experiment of high-temperature clay. The variation of the two distribution factors (m and W0) in the combined TM damage relationship with temperature is analysed. The results show that the damage evolvement speed of the clay shows a curving form getting closed to one as the temperature rises, indicating that the temperature can delay the development of cumulative damage. The damage fundamental modelling discussed is in accord with the testings curves at the various phases of yielding and pre-apex force.
