Authors: AydÄ±nlÄ± Serkan , Alapala Sibel
Published: November 2024

Records of five settled and five nomadic sheep enterprises in Karya-2, a sub-project of the “National Ovine Breeding by Public” project carried out by the General Directorate of Agricultural Research and Policies of Denizli Province, Turkey, were examined in this study. In nomadic and settled enterprises, birth weights, 90-d live weights, 180-d live weights, 90-d daily live weight increase, and daily live weight increase up to 180 d were different. Birth types were different and the twin birth rates were higher in nomadic enterprises. The Karagoz type was more common. The proportion of male and female newborn lambs was similar. The nomadic breeders tended to separate the sheep in the herd more than the settled sheep; the number of animals devoted to breeding in the nomadic systems was found to be higher than in settled systems. The number of lambs per ewe decreased slightly over time from 2014–2018. Although the number of rams decreased, the number of breeding rams increased. There was no marked change in survival rate during the weaning period. There was an increase in live weight and fertility of Karya sheep from 2014–2018. The production averages of sheep in nomadic enterprises were more profitable and yields of measured parameters were higher than in the settled sheep enterprises.

The aim of the present study was to determine the relationship of immunoglobulins and cytokine levels in the milk of Kyrgyz mares during the last period of lactation. For this purpose, seven Kyrgyz mares were used. During the last week of lactation, milk samples were obtained from mares four times at intervals of two days. Physicochemical tests were performed on all collected milk samples, and pH, fat, ash, titratable acidity, and dry matter were measured. Interferon-gamma (IFN-γ), interleukin -2 (IL-2), tumour necrosis factor-alpha (TNF-α), and immunoglobulin G (IgG) levels were determined using commercial enzyme-linked immunosorbent assay (ELISA) kits. Based on the measurements, the lowest IgG level was determined on the last day of lactation (10.23 ± 13.13 μg/mL) and the TNF-α level was determined to be the highest on the last day lactation (61.10 ± 75.69 pg/mL). However, no statistical differences between the days in terms of IFN-γ, IL-2, pH, titratable acidity, dry matter, ash, and fat were found. Varying degrees of positive correlations between the parameters existed and were more pronounced between IgG levels and pH values. As a result, it was concluded that in the last period of lactation in Kyrgyz mares, IgG concentrations decreased and TNF-α levels increased in their milk, but substantial changes in milk composition, immunoglobulins, and cytokine levels in milk did not show positive correlations with the physicochemical properties of milk.
INVESTIGATION OF TOOL WEAR AND THRUST FORCE IN DRILLING AISI 316 AUSTENITIC STAINLESS STEEL USING ELECTROPHORESIS METHOD
Authors: Mahmat Aybars
Published: November 2024

Cutting tool costs are an important component of machining. For this reason, improving machining methods in machining affects the life of the cutting tool. Recently, various machining methods have been used to extend tool life by reducing cutting tool wear. One of these methods is electrophoresis-assisted processing. Electrophoresis-assisted machining is a non-traditional machining method created by the impact of abrasive nanoparticles on the machining area with the help of the generated electric field. Electrophoresis-assisted machining increases the machinability of difficult-to-machine materials with high strength and hardness properties compared to traditional machining methods. In this study, the impacts of various cutting parameters on the drilling performance of AISI 316 L stainless steel material were searched using electrophoresis-assisted drilling (EAD) and conventional drilling (CD) methods. In the study, SiC powder was used as nanoparticles in the solution obtained to create the electric field. Within the scope of the experiments, the effects of different machining methods, cutting speeds and feed rates on thrust forces and cutting tool wear values were experimentally examined. As a result of the investigations, the cutting tool wear and thrust cutting force obtained with EAD are better than CM. Increasing feed rate and cutting speed increased cutting tool wear in both machining methods. It has been determined that the thrust force decreases as the cutting speed increases, while it increases as the feed rate increases.Keywords: Electrophoresis, drilling, cutting force, tool wear, AISI 316

Early diagnosis and optimal management of objective microcirculatory dysfunction to prevent the development of multiple organic dysfunction syndrome
Authors: GORECKI Gabriel-Petre , TOMESCU Dana-Rodica , COCHIOR Daniel
Published: November 2024

Microcirculatory dysfunction plays a central role in the genesis of multiple organ dysfunction syndrome (MODS), being a pathophysiological milestone of it. The mechanism of producing MODS is complex and still incompletely studied, having enough unknowns. It is now known that, despite adequate treatment of macrohemodynamics, there are few correlations between systemic hemodynamic improvement and correction of microcirculatory abnormalities, and the presence of these dysfunctions is more common among patients who do not survive than in survivors. Therapeutic intervention based on evaluation and demonstration of microcirculation dysfunction may help restore splanchnic infusion with definite benefit in selected patients. The method that evaluates in vivo, timely and non-invasive microvascularization is videocapillaroscopy. Although in the past, resuscitation measures were mostly geared towards systemic circulation, the future could be aimed at strategies to restore adequate microcirculation. Basically, the large-scale implementation of oral microcirculation exploration techniques for the diagnosis and monitoring of critical patients, candidates for the development of MODS in intensive care units is an absolute necessity. Being a non-invasive technique, microcirculation evaluation can be performed whenever needed for a diagnosis of certainty.

The paper presents spatial and temporal changes and the current situation of forests in the Lake Sevan basin. The general physico-geographic characteristics of the Sevan basin, the detailed characteristics of the forests in the Sevan lake basin, the natural and anthropogenic changes are presented, and an analysis of the cause and effect relationships of these changes is carried out. The changes in the forest cover and the negative aquatic biological processes that appeared in the lake’s ecosystem as a result of the program of cutting down the water-covered and subject to water-covering forests in the Sevan Lake basin, implemented since 2005, were analyzed. The necessity of increasing forest cover, preventing negative aquatic biological processes in the lake ecosystem and restoring ecological balance through the creation of new forest belts in the lake basin is substantiated. A number of practical proposals are presented to restore the ecological balance of the lake, to prevent negative aquatic biological processes in the lake's ecosystem: afforestation of sloping slopes and erosion-prone areas, strengthening of coastal protection measures, etc. Research is needed to determine the optimal level of the lake in the future, taking into account the changing ecological conditions in the lake basin.

Several possibilities and aspects of the agro-tourism development have been considered a relatively new tourist's direction in Armenia's touristic industry. The most important prerequisites for the development of agro-tourism in Armenia are: high potential of natural resources, ancient historical and cultural heritage (many touristic sights of archaeological, religious, historical character), state programs of agro-tourism development, improvement of infrastructure and rich traditions of national cuisine. Analysis of these assumptions leads to the conclusion that the development of agro-tourism in our country is rather promising.

In the course of working off of mineral deposits, which is carried out basically by open way, huge quantities of technogenic waste is accumulated: overburden rocks, discarded ores and tails of ores enrichment. The given waste includes two interconnected components: mineral-raw and ecological. From geological industrial positions they are potential secondary mineral resources. From ecological position they are sources of environment pollution. In RA has been collected and large quantity of mining waste continues to be accumulated, the wrong policy to which can lead to rather difficult situations.

The hyperbazite massives of the Sevan ophiolite zone have been formed during two stages: first stage – the crystallization of the under crustal and upper mantle peridotite magma with the formation of differentiated layered massive of stratiform intrusion type; second stage – the protrusive intrusion of the consolidated massives through the deep faults and its occurrence in the Mesozoic structures of the alpine circle regions. The layering and dark streak pattern structure of the dunite-harzburgite massives as a result of protrusive intrusion and intensive serpentinitation have not been preserved, and the broken and isolated chromite ore bodies are being scattered in the tectonised hyperbazites. The tectonic blocks of the hyperbazites and of massive ores, which had been broken and moved during the protrusive intrusion by the deep faults, are the relicts of the biggest bodies. Due to these processes the occurrence and manifestations of chromites are scarce in the protrusive massives of the Sevan ophiolite zone, and to expect those regularities of allocations practically is impossible.

The main character in geological structure of copper-porphyritic Kashen deposit belongs to Mesolithic (middle Jurassic, Bathonian age) pyritized secondary quartzites, the origin of which is due to hetero-volcanic fumaroles-solfataric acid gas-water solutes. Copper mineralization is located on the rocks of secondary quartzite formation. In Kashen ore field sericite face of quartzite is exclusively developed. Inner facies are characterized by secondary quartzite-kaolinite, alunite, monoquartzite, sulphur opalite absence in the ore field. Due to fumaroles-solfataric theory these types of quartzite had to be located upper than sericitized quartzite in the higher levels closer to volcanic caldera, but they were not preserved, because of being eroded during more than 170 million years.
