The main objective of the paper was to provide more information about the influence of fibers coming from the end-of-life tires on the behaviour of concrete. Because of their untypical geometrical characteristic they are not eagerly applied as concrete reinforcement. Considering the amount of used tires, the management of this waste would he beneficial for the environment. The paper deals with the typical floor concrete reinforced with three dosages of fibers equal to: 30kg/m3, 40kg/m3 and 60kg/m3. The compressive and flexural mechanical parameters of RSFC were studied. The waste fibers with the shape dissimilar to manufactured fibers did not have a negative effect on the properties of the mix in a fresh state. The compressive strength was slightly affected by the fibers, meanwhile the pronounced influence of RSF on the post-peak flexural parameters was noted. Those parameters increased proportionally with the amount of fibers. However, the scatters in the flexural tests results were increasing with the fibers content. The investigations indicate that the fibers from the end-of-life tires could he applied as a concrete reinforcement. The values of flexural parameters which can be further applied to structural calculations were shown.

Characteristic Localization

The bacterial flora of the gastrointestinal tract differs qualitatively and quantitatively from one colony of mice to another. Certain components of this flora, however, are always present in large and approximately constant numbers in healthy adult mice, irrespective of the colony from which the animals are derived. Lactobacilli and anaerobic streptococci are extremely numerous in the stomach, the small intestine, and the large intestine. In contrast, organisms of the bacteroides group proliferate only in the large intestine. These three bacterial species persist at approximately constant levels in their characteristic localization throughout the life span of healthy animals. They are closely associated with the walls of the digestive organs, and are probably concentrated in the mucous layer. A few experiments carried out with rats and young swine indicate that lactobacilli are also present in large numbers in the stomach of these animal species. It is suggested that some of the components of the gastrointestinal flora have become symbiotic with their hosts in the course of evolutionary development and thus constitute a true autochthonous flora. The other components of the indigenous flora are acquired early in life either through accidental contact or because they are ubiquitous in the environment. The "normal" flora is that which is always present in the environment of the animal colony under consideration.

Annotation. Our study is based on data of 444 patients with clinically, MRI diagnosed and then arthroscopically proved diagnosis of the shoulder’s soft tissue injures. Used the following diagnostic tests: “typical pain localization”, shoulder blade rhythm disturbance, “apprehension”, front driver test, compression rotary test, rear driver test, impedance test Nir, Hawkins, weaknesses of withdrawal, weakness of external rotation, “lift off”, “belly press”, “false paralysis”. We have described the most informative and simple clinical tests. Sensitivity and specificity for each clinical test were calculated. Sensitivity and specificity of these tests are statistically adjusted. It has been found that for clinical diagnostics of damage to the anterior-lower lip of the shoulder joint is more diagnostically attractive is the anterior driver test; for diagnosis of damage to the upper lip of the shoulder joint — compression-rotation test, preference is given to the rear “driver test”; for the diagnosis of subacromial conflict syndrome — a combination of two tests: Hawkins test and impingement test; for diagnosis of lesions of the supraspinatus muscle — test of weakness of the abduction; underarm muscle — test of weakness of external rotation; for the diagnosis of total damage to the rotator cuff (RС) — test “falling” hand; the specificity of “belly press” test is higher than the specificity of “Lift off” test when it is impossible to get your hand behind your back. Thus, tests of characteristic localization of pain and disturbance of the shoulder bladder rhythm are sufficient to suspect the patient of the pathology of the shoulder joint complex itself.
