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.

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.
