This article presents the methodology for determining the real values of kinematic indices which characterizes the mechanical separation of a mixture of solid particles. Mechanical separation of a mixture of solid-solid on surface provided with holes is the most common method of separation. To optimize equipment that performs this operation, both theoretical and practical characteristics are determined. Kinematic indices are part of the theoretical characteristics, helping to identify behavior of solid particles on a surface flat swing. Starting from an experimental batch, real values of the kinematic indices corresponding to up, down and sideways movement on the sieve were determined for the following types of real particles: grain, large grain beans, small grain beans and soybeans.

The overall objective of this study was to evaluate the hemolysing action of Naja nigricollis venom on rabbit blood. To carry out this study, three batches of three rabbits were formed with two control batches and one experimental batch. Each control lot is composed of three rabbits (males or females) while the experimental lot is composed of two males and one female. Each rabbit from the control lots was separately collected in the purple tube (EDTA) and transported to the laboratory for analysis. The rabbits from the experimental batch were also collected distinctly a few minutes after the injection of the venom of Naja nigricollis for the analysis of haematological parameters. However, before the analysis of the hematological parameters of the rabbits from the control and experimental batches, an in vitro hemolysis test of Naja nigricollis venom was performed to verify its hemolysing power. The results showed that Naja nigricollis venom has a dose-dependent in vitro hemolysing power. As for the haemogram, it revealed that the venom of Naja nigricollis has a decreasing effect on blood cells (red and white blood cells), on haemoglobin and on haematocrit, and an elevation on MGVs thus promoting anaemia.

The Title of this paper presupposes the existence of the most important and fundamental document, namely a clear specification of design requirements.The normal sequence of activities after receipt of the specification is as follows: — Design.Prototype and Experimental batch manufacture.Development (and Approval Testing).Production.Customers’ Use.The function of Design and Development determines the ability of the design to meet the specification, and this can be classified as the “Quality of Design.”

The general objective of this study was to evaluate the antivenom effect of minerals from two plants on some vital organs (heart, liver, kidneys and lungs) of rabbits. It was carried out with 36 rabbits (19 males and 17 females) divided into portions E1, E2 and E3. E1 consisted of 2 control lots (3 males and 3 females), and 1 experimental lot (2 males and 1 female). E2 comprised 7 batches of rabbits (2 males and 1 female). E3 consisted of 2 batches of 3 females. Naja nigricollis venom was injected for approximately 20-30 minutes to the animals in the experimental batch of E1, and to those in E2 and E3. Then, E2 and E3 were treated preventively and curatively with minerals, respectively. After the determination of their biochemical and hematological parameters, they were necropsied separately and then their organs were removed, weighed and their appearance was studied. The study revealed that the venom of Naja nigricollis was the cause of death of all the animals of the experimental batch of E1. On the other hand, the use of P2 and P3 as a preventive measure was able to save 1 out of 3 and 3 individuals respectively from the venom. As for P3 as a curative measure, it kept alive 2 out of 3 individuals against the venom. Thus, for the development of anti-venomous phytomedicine, it would be advisable to use the minerals from P3 (ash of Millettia pinnata).

Introduction. The breeding of domestic poultry is an important source to soupplement the human needs in animal proteins with a high biological value. Therefore, knowledge and guidance of the factors that influence poultry production is a guarantee of increasing these productions, both in terms of quantity and quality.Material and methods. The investigation was aimed to administer the 0.05% and 0.1% streptomyces biomass in the recipe of combined fodder, intended for the feeding of young poultry of the Argintie de Adler breed, in order to identify the effectiveness of its administration.Results. The supplementing of streptomyces biomass in the proportion of 0.1% in the recipe of combined feed intended for feeding the poultry of the Argintie de Adler breed, contributed to a 5.1% gross weight gain and a lower specific consumption by 9.9% in chickens from the experimental batch, compared to those of the control batch.Conclusions. The assessment of the dynamic indices of growth and development in chickens of the Argintie de Adler breed, as a result of supplementation of nutrition recipes with streptomyces biomass, has established a sure way to boost the productivity.
