The electronic structures of certain molecules containing oxy-sulphur bonds are analyzed insome detail by means of the molecular orbital method. I t is possible to make rough calculations which, despite the complexity of the system s considered, are nevertheless reasonably reliable. The physical and chemical properties of sulphur dioxide, sulphur trioxide and molecules of the types R 2 SO 2 and R 2 SO are discussed on the basis of these structures. In all these molecules it appears that the oxy-sulphur linkages are best described as double-bonded. A successful correlation between the molecular orbital criterion of bond strengths, namely, the bond orders, and the oxy-sulphur bond force constants may be set up. The measure of agreement attained between observed and predicted properties is quite satisfactory.

And Chemical Properties

Due to their unique structural, physical and chemical properties, cyclodextrins and their derivatives have been of great interest to scientists and researchers in both academia and industry for over a century. Many of the industrial applications of cyclodextrins have arisen from their ability to encapsulate, either partially or fully, other molecules, especially organic compounds. Cyclodextrins are non-toxic oligopolymers of glucose that help to increase the solubility of organic compounds with poor aqueous solubility, can mask odors from foul-smelling compounds, and have been widely studied in the area of drug delivery. In this review, we explore the structural and chemical properties of cyclodextrins that give rise to this encapsulation (i.e., the formation of inclusion complexes) ability. This review is unique from others written on this subject because it provides powerful insights into factors that affect cyclodextrin encapsulation. It also examines these insights in great detail. Later, we provide an overview of some industrial applications of cyclodextrins, while emphasizing the role of encapsulation in these applications. We strongly believe that cyclodextrins will continue to garner interest from scientists for many years to come, and that novel applications of cyclodextrins have yet to be discovered.

Fianite or yttrium stabilized zirconia (YSZ) solid solutions single crystals were known worldwide as jewelry material. The review is devoted to novel applications of the material in the field of microelectronics. A number of modern aspects of the application of fianite in micro-, opto- and SHF-electronics were analyzed in this paper. It was demonstrated that fianite is an extremely promising multipurpose material for new electronic technologies due to unique combination of physical and chemical properties. As a substrate and buffer layer for the epitaxy of Si, Ge, GeSi and AIIIBV compounds (GaAs, InGaAs, GaSb, InAs, GaN, AlN), fianite has a number of advantages over the other dielectric materials. The use of fianite (as well as ZrO2 and HfO2 oxides) instead of SiO2 as gate dielectrics in CMOC technology seems to be of peculiar interest. The unique properties of fianite as protecting, stabilizing and antireflecting coatings in electronics and optoelectronic devices have been outlined. A comparative study of the performance characteristics of fianite and conventional materials has been carried out.

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.
