The nature and interaction of the constituent substances that make up the sour-milk dessert with plant-based fillers have been studied by the method of IR spectroscopy. This method is used to study the diverse nature of substances. The spectral range applied was in the range of 500–4,000 s -1. It was found that the intensity of functional groups absorption in the range of 2,500–3,500 s-1 is due to the valence vibrations of NH-, CH and S-H-groups, indicating the presence of free organic acids, aromatic substances. In addition, in the spectra of sour-milk dessert with plant-based fillers, an absorption intensity in the range of 1,470–1,335 s-1 is observed, which indicates the presence of soluble pectin. Proteins characteristics in the samples are observed at absorption in the range of 3,300–3,500 cm -1, which is due to the valence vibrations of the N-H bond in the -NH2 groups. The use of fruits in the form of a freeze-dried powder together with milk protein concentrate in the technology of sour-milk desserts helps reduce the content of free moisture, hence a stable structure. Sour-milk dessert with plant-based fillers is a system consisting of particles of different dispersion, which will affect its physical and chemical properties. In particular, there is a slight coarsening of whey proteins and redistribution between particles in the range of 1–10 nm and 1–100 nm. The use of plant-based fillers in the form of a freeze-dried powder in the technology of sour-milk desserts would not only improve its physical and chemical properties but also could make it possible to enrich the product with minerals. The mineral composition of the sour-milk dessert is marked by the calcium content (122 mg/100 g), potassium (97 mg/100 g), phosphorus (82 mg/100 g), sodium (50 mg/100 g), and sulfur, iron.

In the present paper forty-five zoosporic members of the aquatic fungi as well as some unidentified species belonging to seventeen genera were recorded <i>Nowakowskiella, Saprolegnia, Pythium, Rhizohlyctis</i> and <i>Achlya</i> were the most common genera of occurrence. Some physical and chemical properties of soil such as temperature calcium content total soluble salts and organic matter content are positively correlated with the of population zoosporic fungal.

This research concentrates on the determination of feasibility of using Eggshell powder and Fly ash as alternate materials of Cement in concrete and their effects on mechanical properties of concrete. The production of cement produces Green house gasses into the atmosphere which pollute the Environment .To overcome this problem we are replacing cement with eggshell powder and fly ash. As the eggshell powder and fly ash are waste material they can available easily and their cost is also very low compared to the production of same amount of cement. The chemical composition of Eggshells is roughly 95% similar to that of cement, which has more calcium content; both physical and chemical properties of cement are almost similar to that of Fly ash. By replacing cement with these two materials in the concrete we can reduce the cost of production of cement and can safeguard the environment. The specimens were prepared and tested for compressive strength, Slump cone test, splitting tensile strength, Modulus of elasticity and flexural strength at 7,14, 28 & 56 days. Results show that the strength of conventional concrete is less than compared to the concrete prepared by replacing the cement with eggshell powder and fly ash.

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.

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.
