The textile industry uses a very great amount of water in their process and then, produces high quantities of colorful wastewater containing pollutants like suspended solids, heavy metals and other inorganic and organic compounds. In this study, real textiles wastewaters were processed in an oxidative photo-catalytic slurry reactor, using commercial ZnO as the catalyst, in order to evaluate its efficiency, the effect of pH, the effect of catalyst loading and its kinetics. The process was tested in a batch reactor, in bench and semi-pilot scales, with excellent data reproducibility observed in the scale-up. Moreover, decolorizations of 97.43 %, BOD and COD reduction were obtained, showing good applicability of the process. According to regional environmental agencies, the final effluents parameters were checked showing good acceptance for the use of ZnO, except for the presence of Zn2+ in the effluent as a disadvantage.

This work aimed to study the leaching characteristics of ceramic blocks produced with the incorporation of textile residues (15% w/w). For this, the procedures of sequential extraction and statistic analysis to validate the occurrence of metals volatilization during the burning process of the ceramic blocks were used. With a 95% confidence interval, the statistic analysis of the metals concentrations in the ceramic blocks, before and after the burning process, showed no metal volatilization. During the sequential extraction, Mn, Fe, Cr, Pb, Zn, Cu and Al distributions were observed mainly in their residual fractions of the textile residue solubilized/stabilized in the ceramic matrix. The sum of all involved fractions in the sequential extraction process is reasonably similar to the total content obtained after the digestion of the original samples with hydrofluoric acid and aqua regia. In both samples, ceramic blocks before and after the burning process, the percentages recoveries of 80 to 98% were achieved. This way, the solidification/stabilization process (S/S) showed to be efficient for the immobilization of heavy metals contained in textile residue (sludge) in ceramic blocks.

The purpose of this study is to determine the behavior of beam-column sub-assemblages castella due to cyclic loading. Knowing these behaviors can if be analyzed the effectiveness of the concrete filler to reduce the damage and improve capacity of beam castella. Test beam consists of beam castella fabricated from normal beam (CB), castella beams with concrete filler between the flange (CCB) and normal beam (NB) as a comparison. Results showed castella beam (CB) has the advantage to increase the flexural capacity and energy absorption respectively 100.5% and 74.3%. Besides advantages, castella beam has the disadvantage that lowering partial ductility and full ductility respectively 12.6 % and 18.1%, decrease resistance ratio 29.5 % and accelerate the degradation rate of stiffness ratio 31.4%. By the concrete filler between the beam flange to improve the ability of castella beam, then the beam castella have the ability to increase the flexural capacity of 184.78 %, 217.1% increase energy absorption, increase ductility partial and full ductility respectively 27.9 % and 26 %, increases resistance ratio 52.5 % and slow the rate of degradation of the stiffness ratio 55.1 %.

Ion implantation is the most versatile and superior surface modification method. It has several advantages compared with other modification methods. In this study, the nitrogen was implanted by a process of ion implantation at 60 keV with different fluences of 1 x 1016, 5 x 1016, 1x1017 and 5 x 1017 ions/cm2. Corrosion resistance of Ti6Al4V and ion implanted Ti6Al4V were investigated by an electrochemical test, at 370C in normal saline solution. ICP-AES studies were carried out to determine amount of ions leached out from samples when kept immersed in normal saline solution. The implanted samples showed variation in the corrosion resistance and microhardness with varying fluences. The sample implanted at 1 X 1017 ions/cm2 showed an optimum corrosion resistance.

Hospital is a unique working area bringing health risk for the worker either of patient or visitor. Society who received health service, health worker and visitor in hospital faced to the risk of occurrence infection or nosokomial infection now called as Healthcare-Associated Infections (HAIs). The occurrence of nosokomial infection in hospital is still on high level. The level of nosokomial infection in hospital for entire the world showing improvement, it's about 9% (variation 3 – 21 %) or more than 1.4 million inpatient spaces (Depkes. 2009). The aimed of this study was to know the implementation of nosokomial infection prevention program in supporting patient safety in Radjiman Wediodiningrat mental hospital. Primer and secondary data was obtained from sanitation department and K3 of hospital, collected using questionnaire interview sheet, polls, and observation using observation sheets. Data obtained using purposive sampling technique. Data was analyzed by descriptive methode and presented into frequency distribution table.

Heat stress is a factor of the physical hazards of work environment that can cause mild to severe of physiological disorders. Makassar Trade Centre (MTC) and Karebosi Link are shopping centers that number of visitors vehicles on weekends reached 6.871 cars and 10.100 units of motorcycle. Heat coming from the vehicle's engine was trapped that potentially cause health problems for employees in the basement parking as a field employee and a computer operator. The aim of this study to find the correlation of heat stress, period of employment, length of work, shift work, and consumption of drinking water with subjective complaints due to heat stress in employees in the basement parking of MTC Karebosi and Karebosi Link Makassar. The type of this research are analytical survey with cross sectional study design to 98 employees of basement parking obtained with exhaustive sampling. Correlation analysis between variables using chi square test. The results showed that employees who are exposed to heat stress are not eligible more likely to have severe complaints is 67,9% with p value = 0,001, employees with long of employment period more likely to have severe complaints is 42,9% with p value = 1,000, employees with un qualify length of work more likely to have severe complaints is 68,4% with p value = 0,014, employees who are worked to b shift (15.00-23.00) more likely to have severe complaints is 44,4% with p value = 0,731, and employees with not enough of drinking water consumption more likely to have severe complaints is 50,8% with p value = 0,018. The conclusion, there are correlation between heat stress, length of work, and drinking water consumption with subjective complaints. While periode of employement and shift work have no correlation with subjective complaints. Therefore it is necessary to periodically measure the work climate, review of work length with appropriate threshold limit of heat stress, and lots of drinking water with frequently (every 20-30 minutes).

The classification and recognition of type on the basis of individual features and behaviors constitute a preliminary measure and is an important target in the behavioral sciences. Current statistical methods do not always yield satisfactory answers. A Feed Forward Artificial Neural Network is the computer model inspired by the structure of the Human Brain. It views as in the set of artificial nerve cells that are interconnected with the other neurons. The primary aim of this paper is to demonstrate the process of developing the Artificial Neural network based classifier which classifies the Iris database. The problem concerns the identification of Iris plant species on the basis of plant attribute measurements. This paper is related to the use of feed forward neural networks towards the identification of iris plants on the basis of the following measurements: sepal length, sepal width, petal length, and petal width. Using this data set a Neural Network (NN) is used for the classification of iris data set. The EBPA is used for training of this ANN. The results of simulations illustrate the effectiveness of the neural system in iris class identification.
