Authors: Polozyuk Olga  Nikolaevna , Lapina Tatyana Ivanovna
Published: April 2020

It has been established that biologically active substances must be used at certain periods in the life of piglets and in certain dosages. The use of a probiotic based on bacteria of the Bacillus of the B. subtillus and B. amyloliquefaciens bacilli strains at a rate of 20 g per head from the 8th to the 28th and from the 35th to 90th days of life caused “overpopulation” of the body of young animals with bacteria. It led to the inhibition of biochemical blood parameters. This consisted in a decrease in the total amount of protein and γ-globulin fraction, and in an increase in the level of glucose in the blood of piglets by 2.1 and 2.6 mmol/L.  Therefore, it led to a violation of protein and carbohydrate metabolism. Using a probiotic at the rate of 5 g per 1 head from the 8th to the 15th day, 10 g from the 24th to the 28th and from the 35th to the 90th day of life allowed improving the redox processes of the body.

Authors: Pronko Nina Anatolyevna , Korsak Victor Vladislavovich , Semykina Lyudmila Vladimirovna
Published: April 2020

They are presented data on the development of landslide processes in the Saratov region, the territory of which is one of the most landslide hazardous due to geological, tectonic and hydrogeological conditions, deep rugged terrain, active erosion, climatic features and anthropogenic factors. The directions of solving the problem of reducing the negative impact of landslides on the condition of territories are shown, the main of which are identification and assessment of the threat, stabilization and retention of the landslide massif. The landslide hazard is determined on the basis of geotechnical, geodetic, hydrogeological, hydrological surveys, weather observations, monitoring and modeling of the landslide process. To stabilize the landslide, its body is drained using a surface runoff system and deep drainage. Then the landslide surface is level off or cut into blocks, ground properties are changed. To hold the landslide massif, retaining walls are used. The results of monitoring the development of a landslide in the October gorge of the city of Saratov, which was formed on the left steep side of the gorge between the equipped spring and the 110 kV transmission line, are presented. Its width along the front reaches 200 m, length 150 m, landslide body area 25-30 thousand m2, total weight about 0.5 million tons. The landslide is closely related to the areas of groundwater outlet, including the Oktyabrsky spring. The calculated strength characteristics of soils in the displacement zone were obtained: on contact with calcareous loams, the angle of internal friction is 36°, specific adhesion is 0.05 t/m2; landslide body density 1.62 g/cm3; on contact with clay, respectively, 10°, 2.5 t/m2 and 1.62 g/cm3. Based on them, the stability indices of the landslide slope and landslide pressure for the zone of active landslide deformations are determined. The safety factor for the calculated transections was 0.99-1.0 in the natural state and 1.05-1.43 with design measures; design landslide pressure 45 tf/m. A system of anti-landslide measures is proposed. It includes the installation of retaining structures from bored piles with grillage and retaining wall; slope profiling with the construction of a counter-banquet; the device of the surface drainage system with the discharge of water into the roadside tray; landscaping of slopes by sowing herbs.

Published: April 2020

The article reflects the results of a study on the use of natural growth regulators with a fungicidal action: «EcoLarix» and «BioLarix». The effect of the drugs on the growth and development of early wheat ontogenesis of varietal variety «Vatan» is shown. Concentrations of drugs that have the maximum stimulating effect on wheat in the two-week-old seedling stage were revealed: for «EcoLarix», the concentration is 80 mg/l. The preparation «BioLarix» is more preferable for stimulating the growth of wheat in the early stages of ontogenesis, causes a manifestation of protective ontogenetic strategy in common wheat - with increasing dose of the drug the morphological integration of plants grows. The protective nature of the plant's response to the drug is confirmed by the fact that the maintenance and enhancement of the morphological integrity of plants requires energy expenditure, and adaptation to stress is always energy-intensive. The variability of the ratio of aboveground to underground mass decreases with increasing dose to 60 mg/l and increases with further increase in the dose of the drug. In general, the limits of variation of this indicator (23.73 – 42.68 %) in the experiments with the «BioLarix» preparation are lower than in the experiments with the testing of the «EcoLarix» preparation (48.89 – 249.70 %). The vitality of soft wheat seedlings with an increase in the dose of the preparation increases with the manifestation of the hormetic effect at a dose of 20 ml/l. It has been established that energy costs in the development of plants are redistributed between maintaining the morphological integrity of plants, stimulating and stabilizing plant growth. Summarizing the response of various indicators of seedlings to the use of the preparation «BioLarix», we can conclude that the optimal dose is 20 ml/l.

GROWTH AND POLITICAL INSTABILITY: A THEORETICAL APPROACH WITH MACRO-DYNAMIC SIMULATION
Authors: Epaphrodite Befio Paulin
Published: April 2020

This work is tending to use theoretical model (economic dynamic model), trying to explain the effect that Political Instability can have on the economic growth. Political instability is considered by economists as a serious issue, detrimental to economic performance. While talking about political unrest, we then think about African countries. Political instability in African countries can therefore be caused by internal and external factors. Coming from a country (Central African Republic) that suffers a lot from Political Instability, this analysis will help to contribute to the stability in my country and in all countries around the world. This work shows the leverage of Political Instability the rate of change in the capital stock per unit of effective labor which is the discrepancy between the actual investment per unit of effective labor ( and the break-even investment , used to keep the capital stock stable. By including the propensity of government change , the result leads to a fall of capital change rate with a subsequent negative effect on the economic growth. This because with a high propensity of government change (c* > 0), the investment incentive will fade leading to a downward tendency of actual investment.

Published: May 2020

In the present work SAE 2205 is welded with AISI 304 using AISI 308 filler wire. TIG welding current was maintained at 110, 120 and 130 Amp and the voltage was set at 40 Volt. A constant welding speed of 0.5 mm/s was maintained for all the experiments. The optical microscopic examination of the welded samples revealed the presence of recrystalized zone, mushy zone at the weld metal SAE 2205 side and columnar grains adjacent to the heat affected zone. The maximum hardness value of Rc 29 was observed in the welded region. The increase in hardness value was attributed to absorption of oxygen in the weld metal during welding and solidification of the weld metal. A maximum yield strength of 354 MPa and an ultimate tensile strength value of 549 MPa were obtained for the samples processed at 130 Amp. Combined transient thermal and stress analysis was performed for the dissimilar stainless steel joints made between SAE 2206 and AISI 304L. A maximum Von Mises stress of 85 MPa was obtained for the weld joints made between stainless steel AISI 304 and stainless steel SAE 2205.

Authors: Pittas Nicholas , Margaris Dionissios , Georgiou Demos , Grapsa Theodoula
Published: April 2020

The purpose of this paper is to study the influence of the composition of the flue gases on the thermal radiation inside the combustion chamber of a three-stage regenerative oxidizer that neutralizes gaseous pollutants for a given plant capacity. This composition is expressed by the corresponding partial pressure of each constituent gas. It is assumed that the flue gases are gray and obey Lambert’s law, so that the gas mixture is assumed to be composed of water vapor and carbon dioxide plus a neutral one. Accurate estimates of each gaseous component emissivity were calculated from the experimental data charts provided by H. Hottel by employing regression analysis. The total emissivity coefficients of the gaseous mixture are evaluated with the help of the above emissivities and they are incorporated into the energy conservation equation that relates the heat exchange among the chamber walls.

Sago palms are the main food crops in eastern part  of Indonesia. Sago productivity can reach 20 to 40 per ha per year, and the trees can be harvested when they are 10 years of age. Due to long duration before harvesting it is important that sago growers could grow annual food crops. The objective of study is to determine the growth of sago palm intercropped with eggplants, and how intercropping aff ects each crop grown as monoculture. The study was carried out from March to July 2018 at Tanjung Peranap Village, Meranti Island District, Riau Province, Indonesia. The experiment was organized in a completely randomized block design with two replications, with sago palm and eggplant as monoculture and as inter cropping. The results demonstrated that young sago palm did not suppress eggplant growth and vice versa. Therefore, eggplants can be planted between young sago palms.

The pineapple vegetative propagation method using crown leaf bud cuttings has potential to produce seedlings of greater uniformity and in larger quantities than other methods. This study, aimed to explore the potential eff ects of concentration and frequency of Benzylaminopurine (BAP) application for increasing the production and quality of pineapple seedlings from crown leaf bud cutting propagation. The experiment used a randomized complete block design (RCBD) with two factors. The fi rst factor was the concentration of BAP (0, 200, 400, 600, 800 ppm) and the second factor was the frequency of BAP application (1, 2, 3 times). Furthermore, this study investigated the eff ects of applying mycorrhizae to accelerate seedling growth and improve seedling quality during production from crown leaf bud cutting propagation. The experiment used a RCBD with one factor (dose of mycorrhiza: 0, 50, 100, 150, 200 spores). The results indicated that the eff ects of concentration and frequency of BAP application and their interaction increased seed production as determined by sprout cuttings at 5 weeks after planting by applying 600 ppm 2 times. Generally, with increasing concentration and frequency of BAP application, leaf chlorophyll content was reduced. However, the application mycorrhiza positively infl uenced the production of seedlings from pineapple crown bud cuttings and improved seedling quality as measured by root dry weight, chlorophyll content, root infection, and phosphatase enzyme activity.

Sago palm has the highest starch content compared to the other source of carbohydrate crops such as cereal and tuberous crops. Sago palm can produce about 200-400 kg per trunk after 7 to 10 years. This research aimed to characterize several sago palm accessions in Aimas, Sorong District, West Papua Province, Indonesia. Eight sago palm accessions were studied, Waruwo, Wasulagi, Wasenan, Wayuluk, Wagelik, Wanegles, Wawun and Wafabala. Among these accessions, there were many diff erences based on trunk morphological characteristics which includes trunk height, diameter, circumference, and bark thickness, leaf number, length of rachis, length of petiole, and spine. Five accessions with potential yield of more than 200 kg dry starch per sago trunk are Waruwo, Wasulagi, Wasenan, Wayuluk and Wagelik. Stem morphological characters aff ect palm sago production, because the starch is located in the pith of the stem.

Kamu Politikalarına Karar Verme Sürecini Yol Bağımlılığı Ekseninde Yeniden Düşünme
Authors: ÖZDEMİRAY Sema Müge
Published: April 2020

Kamu politikası; ilgili literatürde üzerinde uzlaşı sağlanmış bir tanımı bulunmayan ancak vatandaşların ihtiyaçlarını gidermek, çeşitli toplumsal sorunları çözüme ulaştırmak amacıyla siyasi aktörler tarafından yapılan tercihlerin belirleyici olduğu karmaşık bir sürecin ürünüdür. Pek çok içsel ve dışsal faktörün etkisinde oluşan kamu politikaları ile ilgili olarak karar verme aşamasında etkili olan aktörlerin kimler olduğu sorusu kadar, aktörlerin tercihinde etkili olan unsurların neler olduğu sorusu da önem arz etmektedir. Nitekim günümüzün karmaşık ortamında siyasi karar vericilerin rasyonel bir şekilde, belirli standartlar çerçevesinde en iyi ya da en uygun alternatifi tercih edeceği savı sorgulanır hale gelmiştir. Bu doğrultuda çalışmanın amacı, kamu politikalarına karar verme sürecinde aktörlerin tercihlerine etki eden unsurlara dair yapılacak değerlendirmelerde, en temel haliyle geçmişte yapılan tercihlerin gelecekteki tercih ve kararlar üzerindeki belirleyiciliğine vurgu yapan yol bağımlılığı olgusunun kullanılabilirliğine yönelik literatüre dayalı betimsel bir araştırma yapmaktır. Çalışmada; yol bağımlılığı olgusunu ilgili aktörlerin yapacakları tercihlerde inceledikleri alternatifleri sınırlandıran bir olgu olarak negatif şekilde değerlendirmenin mümkün olduğu kadar, karmaşık bir alanda faaliyet gösteren siyasi aktörler açısından karmaşıklığın azaltılması ve farklı tercihlerde bulunmanın alternatif maliyeti dolayısıyla olumlu sonuçlar üreteceği şeklinde değerlendirmenin de mümkün olduğu sonucuna ulaşılmıştır. Kolektif bir sürecin ürünü olan kamu politikaları açısından yol bağımlılığı olasılığının her zaman olduğu ve kamu politikalarına karar verme süreci incelenirken artıları ve eksileri ile bu olgunun göz ardı edilmemesinin gerekliliği de ortaya konulmuştur.

EVALUASI PANJANG DAN ARAH LANDAS PACU DI BANDAR UDARA SULTAN MUHAMMAD KAHARUDDIN SUMBAWA
Authors: Damayanti Lina , Widianty Desi
Published: April 2020

Bandara Sultan Muhammad Kaharuddin Sumbawa saat ini menggunakan operasi landing dan take off searah arah angin. Hal ini dapat mengakibatkan terjadinya overshoot landing karena pesawat menjadi mudah tergelincir dan kurangnya kebutuhan gaya angkat pesawat saat akan take off sehingga landas pacu yang dibutuhkan lebih panjang. Oleh karena itu pemerintah Kabupaten Sumbawa merencanakan perpanjangan landas pacu dari 1.650 m menjadi 1.800 m. Sehingga perlu dilakukan evaluasi terhadap panjang eksisting landas pacu dan arah landas pacu untuk melihat kemungkinan adanya arah landas pacu terbaik untuk operasi take off dan landing. Data karakteristik eksisting landas pacu digunakan untuk menentukan panjang landas pacu berdasarkan keadaan lingkungan lapangan terbang, mengunakan metode ARFL yaitu mengoreksi basic length landas pacu keluaran ATR terhadap suhu, ketinggian, kemiringan landasan dan angin permukaan. Perhitungan panjang landas pacu berdasarkan kemampuan pesawat dianalisa menggunakan aturan ICAO berdasarkan keadaan saat takeoff dan landing normal, kegagalan mesin dan takeoff yang gagal. Sedangkan arah landas pacu menggunakan data arah dan kecepatan angin 2013-2017 dan dianalisa menggunakan software statgraph18. Hasil penelitian yang dilakukan menunjukkan panjang landas pacu 1.650 m saat ini masih memadai dan belum membutuhkan penambahan panjang landas pacu. Berdasarkan pergerakan angin dominan dan crosswind arah landas pacu eksisting 14/32 tenggara-barat laut merupakan arah landas pacu terbaik. Adanya angin dominan searah pesawat masih tergolong aman bagi operasi takeoff dan landing.
