Thermal comfort providing is one of the biggest uses of energy in building. For giving better human comfort, the suitable operation conditions of air-conditioner are the most important. The quick and right approach is necessary. In this paper, a small office is studied to improve office staff staying for a long period of time and achieve the thermal comfort environment for reducing energy consumption. Commercial software, Solidworks, is utilized for modeling the facilities and the Flow Simulation module for analyzing the air properties of the indoor space. Four types of air-conditioner operation are applied to set the simulated conditions, including exterior temperature, outlet temperature and wind speed of air-conditioner, and location of air-conditioner. Predicted mean vote (PMV) and predicted percent dissatisfied (PPD) at specific office areas are further acquired through dynamic anthropometry. For seeking the optimal control factors, both of the full factorial method and Taguchi method are utilized to obtain the PMV of specified location. The analyzed result shows the evaluation speed of indoor thermal comfort by Taguchi method is faster than the full-factorial method. It is concluded that software simulation with Taguchi method shows the successful implementation and higher efficiency for thermal comfort assessment.

Hatchery and culture technology of Humpback grouper has been developed. However,  sometimes it is still found constraint in sedd production and caused instability of production due to failure by many factors. Breeding program become necessary to provide seed with high quality and good genetic variation. Quantitative characteristic selection is one of breeding program to improve productivity in grouper aquaculture. The aim of this research was to produce good phenotyphic and genotypic quality of Humpback grouper candidate broodstock. Selection of Humpback grouper F1 and F3 was done based on quantitative characteristic (body length and weight) and genotyphic characteristic by using ramdom amplified polymorphism DNA (RAPD) method.  The results of conventional selection were found candidate broodstock of Humpback grouper F1 and F3 with body weight range from 170-210 g and 160-170 g consecutively.  Heterozygosity values of Humpback grouper analized by RAPD of F1 and F3 were 0.7940 and 0.7749 consecutively and it was not significantly different. This value emphasis that population of this F3 Humpback grouper was still good to grow for broodstock. Keywords: genetic variation, humpback grouper, F1, F3.

The development of a dental gel that meets modern requirements for the effectiveness and safety of a medicinal product is a serious scientific study related to the selection of active and auxiliary substances, providing the necessary biopharmaceutical and rheological properties of the gel composition, standardizing the quality of the dosage form. The article presents the results of a study on the development of the composition and technology of the soft dosage form of the new dental gel «Matripin- Dent» using pharmacologically active ingredients of the sum of flavonoids from Populus balsamifera L. buds (pinostrobin, pinocembrin, chrysin, techtochrysin) and the sum of terpenoids from Matricaria chamomilla L. (bisabolol oxides A and B, chamazulene). Three bases are selected: fat, gel, and multicomponent. According to the results of pharmacological studies, the optimal composition is a gel base containing polyethylene oxide 1500 and 400. The rheological index of the gel base confirms its thixotropic properties, good spreadability, the ability of the obtained gel to extrude from the tube, and stability. The indicators of control and critical points of the technological process are determined and a technological scheme for the production of dental gel is developed.

An experimental study of GTAW was conducted to determine the optimization of weld parameters on the droplet formation in the surface quality of weld pools. These optimization investigations consisted of welding current, welding speed and feed rate. The strength and surface quality of weld pool were measured for each specimen after the welding parameter optimizations and the effect of these parameters on droplet formation were researched. To consider these quality characteristics together in the selection of welding parameters, the Orthogonal Array of Taguchi method is adopted to analyze the effect of each welding parameter on the weld pool quality, and then to determine the welding parameters with the optimal weld pool quality.

Alternative fuel will be one of the solutions for resolving energy crisis that happening now. Methanol gel is one of them that have lot of benefits. In this paper will be discussing how to increase quality of methanol gel. The quality that we pursue is to decrease number of explosion when the process of incineration was executed. Only four factors observed in this study, include; using purple dye, number of NCl volume, number of layer, and using water as raw material. Experiment method used in this study was Taguchi Method with L8 orthogonal array and twice repetitions. The results that we get were quite surprising. Using ANOVA with 95% level of confidence as analyzer the results, show us that the influencing factors for methanol gel quality were using purple dye, number of layer, and using water.

The main purpose of this research is to optimise the injections moulding parameters in processing of thermoplastics samples made from Polypropylene (PP)-Clay with the fraction of 95% PP and 5% Clay, through Design of Experiment -Taguchi Method. The selection of defects or responses that need to be controlled for these thin layer products were warpage and shrinkage. The parameters that were taken into consideration were packing pressure; melt temperature, screw speed and filling time. In this research, the L934 orthogonal from Taguchi Method was chosen as the experiment setup. According to the results, 170°C of melt temperature, 80% of packing pressure, 70% of screw speed and 3 seconds of filling time gave minimum shrinkage of 3.45%. As for the warpage results, the best parameters combinations are 170°C of melt temperature, 70% of packing pressure, 70% of screw speed and 2 seconds of filling time. The Analysis of Variance for warpage shows that screw speed was the most significant factor with 41.83% contribution. As for shrinkage, the most influential factor was packing pressure with 98.48% contribution. Two factors have been pooled which are screw speed and filling time. Based on these findings, it is concluded that by controlling the optimum parameter setting, the best quality of desired product can be easily achieved and maintain through the in process production.

The aim of this study was to investigate the effect of conformation of chickens of different genotype on the yield of breast meat. As a typical example of the chickens of very poor conformation pure breed Naked neck chickens were taken, fattened 8 and 10 weeks (groups K8 and K10). As an example of good conformation, an imported hybrid of chickens was taken, known for its broiler qualities and as medium growing hybrid, Red Bro (R). The second experiment included commercial hybrids of fast growth (Ross, Cobb and Hubbard) reared according to all technological standards of intensive fattening until the age of 42 days. The results obtained were contrary to the conclusion obtained a few decades ago, at the beginning of the study the conformation of chicken, by Scots and Darrow (1953), according to which the selection of chickens of heavy type, despite the fact that, to some extent, it had improved meat yield of the breast, did not significantly improve slaughter traits of fattening chickens, confirming that better conformation and higher body weight had a positive impact on improving relative share of breast, i.e. white meat. The results regarding the slaughter traits of chicken genotypes of different conformation suggest that breeding - selection work to improve the conformation of broilers significantly improved slaughter yields and breast meat yield. In this sense, the conformation can be treated as an indicator of the slaughter value of carcasses, rather than an aesthetic category.
