In this paper we present the results of a study of the physical and chemical properties of activated lignocellulose obtained in the process of steam explosion treatment of various breeds of wood. It is shown that fibrous material has a high potential for scientific and commercial use: in the field of production of pulp for paper and cardboard production in a more efficient way, to obtain microcrystalline cellulose by hydrolysis, to produce coarse lignocellulosic fibers for the production of construction and insulation boards with new properties. The scope of activated lignocellulose is not limited only to these directions, but can be significantly expanded due to the competent use of its physical and chemical properties.

1-Acetoxy-1,3-butadiene was prepared by the reaction of crotonaldehyde with acetic anhydride in the presence of potassium or sodium acetate. The product was found to consist of two forms which, from their physical properties and infrared spectra, appear to be cis and trans. Mass and ultraviolet spectra, and methods of analysis are also reported. The cis form was found to be a substantially stronger inhibitor than the trans in the bulk polymerization of vinyl acetate using benzoyl peroxide as catalyst.

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.

And Chemical Properties

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.
