    The study aimed to draw attention to the camel's hair available in Afif province and to give information about their physical and chemical properties, and improve their properties. The researchers' collected 50 samples of camel's hair, analyze, and then add improvement material. The study concluded that the Afif Province camel's hair have properties that can converted into textile materials. The softness are from 24.5 to 29 μ, (B and C1) according to the classification of the German system GER, and between 58 S And 60 S according to the classification of (USA, AUS, GRB). The thickness between 5.3 - 12 cn/ tex. The length between (3.8 - 25.5 cm), and the colors of camels hair (Brown, light brown, light creamy, dark creamy). The chemical properties were similar to the global chemical properties of wool, Absorption of moisture from 0.10% to 0.26%, the protein content from 52% to 95%, and its capable temperature to 140 °C without occur softness or fusion, and after 140 degree centigrade the decomposition occurs. Characteristics of the camel's hair can improve by adding some chemicals, such as acetic acid to improve the softness without affecting the durability, or by mixed with other fiber.

<p class="p1">This research was aimed to study the influence of animal age and acetic acid solution concentration on physical and chemical properties. The experiment used Randomized Complete Design (RCD) with two factors and three replicates. The first factor was animal age consisted 3 levels (5, 7 and 9 months). The second factor was concentration of acetic acid solution consisted of 3 levels (2, 4 and 6 percents). The result showed that interaction of animal age period and concentration of acetic acid had no significant effect on gel strength, moisture content, ash content and fat content of pig skin gelatin. It was concluded that pigskin gelatin from ages of 5, 7 and 9 months and concentration acetic acid 2, 4 and 6 % had similar physical and chemical peoperties with the commercial gelatin.</p>

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.
