Currently, the final destination of organic residues and aquatic macrophytes does not occur effectively, directly interfering with the environment and causing environmental problems. Therefore, the work aimed to reuse the organic waste from UNOESTE Campus 2, which comes from the university restaurant, urban cleaning and dairy cattle manure, as well as the aquatic macrophytes of the Cica dam in the municipality of President Prudent, using the vermicomposting technique in different treatments, analyzing the physical and chemical properties of the final compound and suggesting a better destination for such residues. Four treatments were carried out, with three repetitions each, namely: T1 (Dung, Organic waste), T2 (Aquatic Macrophyte, Dung, Organic waste), T3 (Urban cleaning waste, Dung, Organic waste) and T4 (Macrophyte, Waste urban cleaning, manure, organic waste).After collecting the compost, laboratory analyzes were carried out, which showed a significant increase in humidity when compared to the parametersof Normative Instruction SDA No. 25 of 2009. In the treatments carried out, T4 was highlighted by the breeding of earthworms. Therefore, through the execution of this work it was possible to confirm that the application of the vermicomposting technique is feasible for the treatment of organic waste.

This paper represents a summary of most important research activities in sucrose crystallization, in which the Department of Carbohydrates and Cereals, part of the University of Chemistry and Technology (UCT) Prague, has been involved over the last 25 years. A wide range of these projects has been carried out in cooperation with other research institutes, universities and industrial partners. These activities can be divided into four main research areas that are interconnected and support each other. – Physical and chemical properties of sucrose and sugar solutions; – Growth kinetics of sugar crystals in pure and technical sugar solutions; – Simulation and mathematical modeling of new processes and technologies; – Experimental work for industry and cooperation with industrial partners.

Kitchen waste recycling is an environmental friendly measure. Two identical samples of kitchen waste were conducted for composting by the barrel-type of method in this study. Compost produced from these two experiments was analyzed for their physical and chemical properties. No significant difference was found between the compositions of the two kitchen waste samples. The major components of the two kitchen waste samples of this study were water content (averaged 72.7%), followed by combustible constituent (about 25.6%). The carbon-to-nitrogen (C/N) ratio was between 15 and 25. Compost by the simple barrel method had the average C/N ratio of 12. For the simple barrel method, because its enzyme fermentation lasted longer, the maturity of the compost was better. The compost samples had the average germination rate of 95%, indicating the simple barrel composting method definitely has better maturity. When comparing the compost samples produced in this study to the standards given by the Council of Agriculture, Taiwan, the simple barrel compost qualified all the criteria. The simple barrel composting method is a convenient and easy method for recycling and processing organic waste, especially kitchen. The compost products, both solid and liquid, can be used for agricultural purposes.

The structure of sanidine was described by Taylor in 1933, and Taylor, Darbyshire, and Strunz in 1934 extended the investigation to include the potassium-barium-felspars and albite, and presented a small amount of experimental data for potash-soda perthitic felspars and for members of the plagioclase series. X-ray work on the potash-soda perthitic felspars has recently been reported by Ito and Inuzuka, by Ito, and by workers in this laboratory, and a preliminary report of an examination of the plagioclase felspars is given in a thesis presented by one of us (S.H.C.) in 1939 for the degree of Ph.D. in the University of Manchester.The investigations to be described in this paper, as well as those already published from this laboratory, form part of a programme of researches dealing with various aspects of the problem of felspar structure, undertaken in an attempt to obtain a correlation between the physical and chemical properties on the one hand and the details of the structure on the other.

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.

Synthesis Of Materials

Biomimetics involves investigation of structure, function, and methods of synthesis of biological composite materials. The goal is to apply this information to the design and synthesis of materials for engineering applications.Properties of engineering materials are structure sensitive through the whole spectrum of dimensions from nanometer to macro scale. The goal in designing and processing of technological materials, therefore, is to control microstructural evolution at each of these dimensions so as to achieve predictable physical and chemical properties. Control at each successive level of dimension, however, is a major challenge as is the retention of integrity between successive levels. Engineering materials are rarely fabricated to achieve more than a few of the desired properties and the synthesis techniques usually involve high temperature or low pressure conditions that are energy inefficient and environmentally damaging.In contrast to human-made materials, organisms synthesize composites whose intricate structures are more controlled at each scale and hierarchical order.

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.
