Reflection of Azerbaijan's relations with foreign countries in bayati and fairy tales

Azerbaijan had attracted with the place where the trade ways crossing since the old times. Caravans coming from East to West, sumpey from North to south passed through our country. Local merchauts took products which produced with the wealthy assortments as raw silk, panne velvet, atlas clpothes, simply various products to foreign countries in turn. It is natural that, both local and foreing merchauts arrived in our country leave with separate material boons equal which they brought to our country with, them as myth, tales and legends and told everything that hearings here in foreign countries. But all these obsorbeed in various bayaties and legends created by our rich imaginative people, arrived in our time. Key words: bayati, tale, Iraq, Suriya, Phrangistan

Vibration and Noise Reduction Analysis of Sheet Metal Structures with Damping Layer

Vibration reduction in term of lower acoustic noise level increases e.g. the passenger comfort, fulfills acoustic manufacturing standards, decreases the transportation influence on the environment etc. The basic sheet metal structure is complemented with damping layer which absorbs the vibration energy. The frequency response experiment analysis of the component structure with damping material helps to validate the separate material models used for predictive simulations.

By-products of grain cleaning: an opportunity for rapid sampling and screening of wheat for mycotoxins

By-products of cereal grain cleaning were analysed for a number of mycotoxins. Deoxynivalenol (DON) was the most frequently detected in by-products from commercial-scale cleaning procedures (maximum 2.94 mg/kg), followed by zearalenone (ZEA; maximum 0.045 mg/kg) and ochratoxin A (OTA; maximum 0.019 mg/kg). These three mycotoxins were also the most frequently detected in four different fractions collected from wheat run through a dockage tester, a piece of equipment used in the Canadian inspection process to separate material other than grain from wheat. Concentrations of mycotoxins were highest in the ‘light dockage’ fraction that contained dust and roughage such as glumes, fragments of stem, or rachis. Mycotoxin concentrations in this fraction reached up to 32 mg/kg (DON), 0.532 mg/kg (ZEA), and 0.249 mg/kg (OTA). Concentrations of DON in light dockage were significantly correlated with concentrations in whole grain that was un-cleaned or had undergone basic cleaning, indicating that the light dockage fraction could be used as a readily available matrix for the rapid screening of DON in wheat. This would eliminate the time required for additional sampling and preparation of whole grain, and move towards a truly rapid method for the screening of DON in wheat.

Structural Performance of a New Column’s Prototype Made by FRP Pultruded Material and Light Concrete

This investigation presents some evaluation based on the experimental and numerical results obtained on the compression bearing capacity of new columns prototype made by FRP (Fibre Reinforced Polymer) material and concrete. In detail that is the junction due to the assembly between hollow FRP profiles made by pultrusion process with glass fibres and thermosetting matrix vinylestere, and very light concrete casting inside. To better understand the eventually influence related to the hollow shape employed, the study consider both the case of circular and square profile. Due to the novel of the research, a not negligible part of the research is dedicated to test previous the separate material, that is the plane concrete and the hollow GFRP profile, and then the prototype (concrete+GFRP) also considering two different way of load application. Particularly we applied in the first case the load to only the core of the sample, on the plane concrete, and then to the total cross section. This choice allows to evaluate the role and the influence of the bond strength along the length of each sample.

Isolation and Identification of Thermophilic Protease Bacterium 0701 and its Protease Characterization

Soil was collected from Huguangyan of Zhanjiang city and regarded as separate material, It was screened thermophilic protease-producing bacteria though dilution flat, transparent circle and Folin method. Strain 0701 isolated was identificated by its morphological features, physiological and biochemical characteristics and 16s rRNA. This experiment also researched on the genetic stability of enzyme producing, and different temperature, pH influence on proteases activity. 25 high temperature-tolerance protease producing strains were isolated, which accounted for 28.1 % of all the isolated strains. Among them, strain 0701 proteases activity was 247 U/mL and it was far higher than that of proteases for other strains and the most optimum reaction temperature and pH of the proteases were 70oC and pH 7.0, respectively, and retained high enzyme activity within 50-80 oC, pH6.5-9.0. The strain 0703 still had the ability to produce protease after consecutive 4 generation, and was identified as Bacillus subtilis by morphological, physiological-biochemical characteristics and 16s rRNA.

Modelling of Damage in Blanking Processes

Fracturing by ductile damage occurs quite naturally in metal forming process due to the development of microcracks associated with large straining or due to plastic instabilities associated with material behavior and boundary conditions. Metal forming processes generally introduce a certain amount of damage in the material being formed. Predictions of the damage formation and growth in a series of forming steps may assist in optimizing the individual operations and their order. This is particularly true for operations such as cutting and blanking, which rely on the nucleation of damage and cracks in order to separate material. In this work numerical simulation of the blanking process, using Deform 2D, taking in account the damage, has been performed. In order to evaluate the accuracy of the numerical solution, experimental test have been performed. Furthermore a numerical – experimental correlation has been carried out.

Morphologic evaluation of the use of a latex prosthesis in videolaparoscopic inguinoplasty: an experimental study in dogs

PURPOSE: To evaluate the morphological aspects of the behavior of 4 types of latex biomembranes implanted in preperitoneal videolaparoscopic inguinoplasty. METHODS: Sixteen inguinoplasties were performed in 12 dogs: group 1 received an impermeable latex biomembrane in the right inguinal region and a prolene prosthesis, as control, in the contralateral inguinal region; groups 2, 3 and 4 received latex biomembranes respectively containing impermeable polyamide, 1-mm thick porous polyamide and 0.5-mm thick porous polyamide. Macro- and microscopic evaluations of the inguinal region and of the removed implants were made on the 7th, 14th, 21st and 28th days in group 1 and on the 28th postoperative day in the other groups. RESULTS: We observed absence of hematoma, seroma and infection; presence of tortuosities; induction of vascular neoformation, inflammatory reaction and collagen deposition, and full encystment of the latex biomembranes, except that with fine porous polyamide, which was partially incorporated, with the formation of microcysts. No latex biomembrane induced fibrosis as observed in the prolene control group. CONCLUSIONS: The biomembranes maintain induction of the healing process without fibrosis, are fully encysted and, except for the one with fine porous polyamide, are not incorporated into adjacent tissues. The latex biomembrane, with or without polyamide, is not recommended as a separate material for preperitoneal inguinoplasty.

Development of Micromechanics Finite Element for Analysis of Composites With Local Damage

An analysis model is presented to analyze continuous fiber-reinforced composite structures with some local damage such as matrix cracks. Two separate material properties of fiber and matrix are used in the analysis model instead of a smeared-out global anisotropic material property. Stresses acting on fibers and stresses acting on matrix are computed directly. If there are local matrix cracks in the direction perpendicular to the fiber orientation in a composite structure, the broken matrix is modeled not to sustain any tensile stress in the fiber direction. A finite element formulation is derived for the analysis model. Some numerical problems are presented to test the proposed analysis model.

Thin-layer chromatography of component A of the menstrual stimulant

Thin-layer chromatography has been adapted to separate material of high biological potency from much of the inactive material contained in component A of the menstrual stimulant. The chromatoplates were developed with solvent mixture of chloroform, methanol, and water (60:10:1). Visualization of the spots was carried out by various methods; ultraviolet fluorescence of the charred material appeared to be the most sensitive. Samples of ricinoleic and phloionolic acids were used as reference standards. The biological active material of the component A preparations always ran just in front of phloionolic acid. Menstrual fluid was collected in vaginal cups; total volume and crude liquid extract measurements were also carried out on the fluid. uterine smooth muscle stimulant; menstrual flow rates Submitted on October 1, 1963
