Published: March 2019

Iron ore raw materials quality to a great extent determines technical and economic indices of metallurgical production. A brief characteristic of main types of iron ores of Russia quoted. It was shown, that they require concentration for utilization them in metallurgical production. Concentration flow charts of main types of iron ores considered. Main ways of iron ore raw materials concentration flow charts perfection directed on concentrates quality increase, concentration specific costs decrease and increase of raw materials utilization complexity. At Lebedinsky mining and concentration complex (MCC) at the expense of additional milling and concentration of high quality concentrate, a super-concentrate is produced having the iron mass content no less than 69.5% and silica content no more than 3.5%. The increase of iron mass content is 1.5–2%. At Mikhajlovsky MCC additional concentration of regular concentrate with iron mass content 65.5–66% enables to produce a super-concentrate having the iron mass content no less than 69% and silica mass content no more than 3%. The increase of iron mass content is 3–3.5%. Fine hydraulic screening is used at Kostomuksha and Kovdor MCCs for adjusting of regular concentrates. The undersize of sizing screens is a high quality concentrate, and oversize fraction is an intermediate product subjected to additional milling and concentration. When using the fine hydraulic screening, the super-concentrates are not obtained. Indices of super-concentrates production with application of separation in an alternative magnetic field quoted. Low complexity of iron ore raw materials utilization is typical at concentration of hematitemagnetite quartzite ores. In Russia the hematite-magnetite quartzite ores are mined and concentrated at three MCCs as follows: Olenegorsky, Mikhajlovsky and Kimkano-Sutarsky. Flow-charts and indices of magneto-gravitation concentration quoted, applied for hematite concentrate production. Stage separation of not only tails but also of concentrates is one of methods of expenses decreasing. A diagram of concentrate stage separation with application of concentration method or fine screening considered. Results of industrial application of flow-charts with concentrate stage separation quoted, the application taken place at Kachkanar MCC with application of two methods – wet magnetic concentration and fine hydraulic screening.

Published: March 2019

Input of intensifying additives, influencing the strengthening of iron ore pellets, can be one of methods to strengthen the pellets and to decrease the volume of fines in them. Boron oxide ore borate ore can be used as such additives. Study of technology aspects of boron-containing pellets production and elaboration of technology of boron input into Kachkanar vanadiumcontaining raw materials was the purpose of the study, aimed at exclusion from BF burden of sinter, which does not contain vanadium. A possibility was justified to use borate ore at iron ore pellets production by a partial substitution of bentonite. Influence of borate ore additives on pellets metallurgical properties studied. As a result of laboratory studies it was determined, that the borate ore has not binding properties and its utilization is possible only in a mixture with bentonite. Optimal content of borate ore in pellets determined, exceeding of which a decrease of reducibility is observed, accompanied by a considerable swelling, which makes impossible the utilization of such pellets in blast furnaces. It was shown, that input of optimal volume of borate ore additives enables to keep the reducibility and swelling at the level of Kachkanar pellets being produced. The mechanism of borate ore content influence on strength characteristics of burnt pellets and their behavior during reducing studied. The regularity of borate ore additives influence on cold and hot pellets strength determined. It was determined, that at input of 0.5% of borate ore practically does not influence on the pellets reducibility while swelling will be constant. The input of borate ore up to 2% will result in a sharp increase of swelling. The decrease of reducibility with simultaneous increase of swelling of pellets having more than 0.5% of borate ore does not allow using such pellets in blast furnaces. Recommendations provided for slag regime optimizing, decreasing of metal losses with slag and test BF heats of pellets, having optimal additives of borate ore and bentonite carrying out.

Utilization of sewage sediments as a soil modifier is one of effective ways of man-caused disturbed lands reclaiming. To meet modern ecology requirements to reclaimed territories, the sediments must be safe by sanitary indices, have good organoleptic and grain-size properties, apart from being correspondent to norms by heavy metals and other toxic substances content in them. Wastes of urban sewage treatment plants were studied, as follows: raw sediments; excessive active mud, a mixture of wastes. Wastes of JSC EVRAZ ZSMK operation were used as neutralizing additives, as follows: aspiration dust of limestone burning plant, blooming scale. Studies showed a significant decrease in the content of water-soluble compounds of zinc, lead, copper, fluorine due to their precipitation when reacting with the added additives. The effectiveness of the deposition depends on the type of additive, its content, mixing conditions. By simply mixing of the neutralizing additive with the sample under investigation, a decrease of concentration of water-soluble compounds of zinc, copper, and fluorine was achieved. The selective effect of additives on individual elements established. Lime dust provided an excellent effect on zinc – a decrease by 50%, but had no effect on copper. The addition of scale led to a 25% reduction in the content of water-soluble copper, but did not lead to zinc precipitation. Regarding fluorine, lime was significantly more effective (a decrease by 53%) comparing with scale (a decrease of 27%). The total reduction of water-soluble compounds of the elements under study was 32.2% for lime and 32.6% for scale. Mixing the raw sediment with a neutralizing additive under heating conditions contributed to a significant increasing effect regarding copper: the decrease of its water-soluble ions down to 77% was obtained.

Published: March 2019

For the first time, gravity pulsations were detected during the processing of stationary observations at the Geodynamic range of RAS in Bishkek (2014). Then, similar surges were detected in stationary seismic observations in the city of Voronezh, which simultaneously coincided with the gravimetric fluctuations in Bishkek. Later, gravity pulsations were detected at Artie, Perm and Vladivostok stations. Seismic ripples are also found in Southeast Asia. In coastal zones and in the ocean, additional pulsations occur due to atmospheric processes (typhoons, cyclones, etc.). Pulsations of non-tidal variations of gravity and seismic fields are global.

The efficiency of applying air conditioning units for comfort and energetics for a certain period, as well as any power plant, is determined by the effect obtained, primarily in the form of reducing fuel consumption over the year or increasing the production of electrical (mechanical) energy in the case of air conditioning at the heat engine inlet and by annual cold production as an indicator of the efficiency of using the cooling capacity of comfort air-conditioning plants. Since in both cases the effect depends on the duration and depth of cooling, it is quite justified to estimate it in the first approximation by the thermal hourly potential, which is the result of summation hour by hour of air temperature drops multiplied by duration of operation at a lowered temperature and, thus, takes into account current climatic conditions. Obviously, the realization of the cooling potential (air conditioning) of the ambient air depends on the installed (design) cooling capacity of the air conditioning units, which, in turn, must take into account the fluctuations in thermal loads in accordance with the current variable thermal and humidity parameters of the ambient air. Based on the different rates of the increment of the annual thermal hourly cooling potential with an increase in the installed cooling capacity of the air conditioning unit due to a change in the heat load in accordance with current climatic conditions during the year, it is necessary to choose such a design thermal load on the air conditioning unit (its installed cooling capacity) that ensures maximum or close to it the annual thermo-hour cooling potential at a relatively high rate of its increment, respectively, and the effect of cooling in the form of a decrease in fuel consumption per year in the case of air conditioning at the inlet of heat engine and annual cold production of comfort air conditioning units. It is shown that under the same climatic conditions during the year and the depth of ambient air cooling, the rational values of the design cooling capacity of air conditioning units for comfort and energy purposes are the same.

It is introduced the concept of the degradation coefficients of the parachute canopy power structure materials strength characteristics. These coefficients are defined as the ratio of destructive loads after long-term operation or storage to the original, taken at the design stage. It is noted revealed the dependence of safety factors on degradation factors. It was determined the condition of safety factors equality after the long-term operation and during the design stage. It was shown that the ratio of maximum permissible loads is equal to the degradation coefficient. It was defined as the method for calculating the load on the parachute during deployment. It was applied to the simplified approach proposed by N. A. Lobanov. The following statement was determined according to this approach: a dynamic coefficient equal to two, a method for determining the dangerous section of the dome when assessing the fabric strength, the dependence of the speed at the moment of full filling of the parachute canopy from the generalized empirical coefficient. Characteristics of the standard atmosphere, depending on the height of throwing the aircraft are given by approximating functions. The movement of the body until the parachute opens is given in the form of differential equations with known initial conditions. The equation allows you to find the falling speed at the initial moment of the parachute opening, depending on the delay time. It is given the speed of steady free fall without the introduction of a parachute into the work and with a stabilizing parachute, the landing speed with the main parachute. The dependences of the maximum permissible loads on the dome at the opening moment on the strength degradation factors for the fabric of the dome, lines, and free ends of the suspension system are established. It was proposed the correlations for the maximum allowable speed at the time of the beginning of the parachute opening on the requirements of strength. This speed determines the maximum allowed landing speed for a particular type of parachute after long-term operation or storage.

The current level of technological development is characterized by the constant complexity of the products. For its production requires processing a large number of parts of complex shape. Mathematical modeling is an effective and economical way to solve many technical problems. There are various ways to ensure the necessary cleanliness of machine parts or reduce the negative effects of technological pollution. Existing methods of finishing and cleaning parts on the physical-chemical effects on the material during processing are divided into several groups. The most widespread are both mechanical methods in which the removal of defects is carried out by mechanical action on machined parts of tools and chemical and mechanical methods in which there is a simultaneous mechanical effect of the tool and the chemical action of the external. The gas-dynamic method of removing defects that occur after the preliminary metalworking of parts of aircraft objects seems to be very effective. The mathematical model of this process is the system of laws for the conservation of the dynamics of a viscous heat-conducting gas, the physicochemical characteristics of which are established in an experimental way. The construction of a gas-dynamic model of the physical process of finishing parts as an arbitrary spatial form and the material of manufacture is presented. On the basis of the general laws of conservation of the dynamics of a viscous heat-conducting gas, analytical forms of solutions for the kinematic and dynamic characteristics of a high-temperature flow are obtained using the example of a flat channel simulating the surface of a part being cleaned. It is shown that in the flat case the conservation laws have a linear form, which provided exact solutions for the kinematic characteristics, such as the velocity and vorticity of a viscous gas flow, which play a major role in calculating the dynamic and thermal characteristics of the flow. The use of a generalized apparatus of vector-tensor analysis is fundamentally important in order to obtain integral representations of the solutions of differential forms of the laws of conservation of momentum and energy in the control region. Control of gas dynamic and thermodynamic parameters of the flow is able to provide a high-quality surface.

The factors affecting the efficiency of ion cleaning of CuAl9Fe4 bronze substrates and 12X18H9T stainless steel applying the «Вихрь-К» pilot plant were investigated. The unit is equipped with an inverse magnetron sputtering system with a gas anode, partitioned by cathode assemblies and ensures the creation of radial plasma flows. It was investigated the composition and morphology of the substrates’ surface and the WC-type coatings formed on them, applying «СЭМ 106» scanning electron microscope. It has been established that the effectiveness of the ionic cleaning of the substrate surface is influenced by the magnitude of the potential, under which the target cathodes are in relation to the installation case. Under conditions of relatively high positive potential, purification does not occur at all. At the same time, at a low potential, the sputtering of the material of target cathodes is observed. Therefore, it became necessary to experimentally establish the mode of ion cleaning of CuAl9Fe4 bronze substrates and 12X18H9T stainless steel using an inverse magnetron sputtering system with a gas anode, partitioned cathode nodes, and radial plasma flows, ensuring high-quality cleaning of the surfaces of the substrates without spraying the cathodes. The mode is determined by the electrical resistance of the resistors, which are connected to the cathode nodes. The morphology and surface composition of various parts of the bronze and steel substrates, both after their ionic cleaning and with the deposited coating such as tungsten carbide, was investigated. It was established that, in contrast to coatings formed using this system with axial plasma flows, when using radial flows, there is no dependence of the surface morphology on the remoteness of the investigated coating area relative to the substrate edge. This may be due to the characteristics of the electric field and plasma flows in the vicinity of both target cathodes and metal substrates. Thus, when forming coatings of the WC type on metal substrates with the help of magnetron sputtering systems, there are certain advantages of applying radial plasma flows compared to axial flows.

The rapid advancement of pervasive computing, IoT and wearable systems, given rise to low-power internet-based systems in elimination of distance complications by application of Wireless Sensor Networks, which consists of sensor, server and Cloud servers to sense various environmental readings and monitor the condition based on the data. Due to the association of vital data, and transferring it over an insecure and public communication channel, there is a critical prerequisite for sensor authentication, data integrity and data privacy. In this context many researchers had proposed various schemes for user authentication and secure data transmission over Cloud server. In this paper we proposed a three-factor user authentication and key agreement protocol for cloud server and claimed that the proposed protocol is efficient, secure and lightweight. The experimental analysis shows that the proposed scheme is resistance to well-known cryptographic attacks. Though the proposed scheme resists major cryptographic attacks, after in-depth analysis, we demonstrate that the scheme overcome many security pitfalls such as failure to resist replay attack, known session-specific temporary information attack, and failure to resist stolen-verifier attack.

ABSTRAK

Pembentukan Badan Usaha Milik Desa (BUMDES) merupakan sebuah langkah maju yang dilakukan oleh perangkat desa dalam rangka meningkatkan pendayagunaan segala potensi ekonomi, kelembagaan ekonomi, serta potensi sumber daya alam dan sumber daya manusia untuk meningkatkan kesejahteraan masyarakat desa. Pada perkembangannya, dengan dikeluarkannya regulasi yang mendukung UU Desa, yaitu PP No. 60/2014 tentang Dana Desa. Peraturan ini mengatur bahwa desa yang sekarang sudah bisa aktif turut membangun, perlu disokong dengan dana. Artinya, dana desa diadakan dengan dua cita-cita: pemerintah desa lebih bisa sanggup melayani kebutuhan warga, sekaligus warganya lebih aktif berinisiatif. Salah satu wadah untuk memajukan ekonomi desa adalah melalui Badan Usaha Milik Desa atau BUMDes. Desa Sebayan merupakan Desa Administrasi dari 18 Desa dalam wilayah Kecamatan Sambas yang berjarak 8 Km dari Ibu Kota Sambas Saat ini desa Sebayan telah membentuk BUMDes guna menampung serta menjual produk – produk berupa pupuk, bibit serta obat-obatan pembasmi hama dengan membuka toko. Selama ini produk – produk tersebut masih dipasarkan atau dijual hanya pada lingkup warga sekitar (lokal), padahal dengan perkembangan teknologi yang semakin meningkat sekarang ini sistem penjualan pada BUMDes sudah seharusnya menggunakan sistem penjualan berbasis online. Dengan adanya sistem penjualan online diharapkan dapat memperluas segmen pemasaran produk BUMDes tidak hanya bersifat lokal, namun meningkat hingga antar desa, kecamatan, kabupaten bahkan ke level nasional dan internasional. Keberhasilan BUMDes tidak hanya pada jumlah produk yang ditawarkan, namun juga bergantung pada perangkat atau sember daya manusia dalam melakukan manajemen pengelolaan BUMDes itu sendiri. Kendala yang dihadapi saat ini adalah lemahnya pengetahuan dan kemampuan pengelola BUMDes dalam hal pemamfaatan Teknologi Informasi (TI) dalam melakukan pemasaran dan penjualan secara online atau yang dikenal dengan istilah   e-commerce. Tujuan pengabdian masyarakat ini adalah ingin memberikan pengetahuan dan keterampilan kepada perangkat pengelola BUMDes “Usaha Bersama” desa Sebayan melalui pemanfaatan teknologi e-commerce guna memperluas pemasaran penjual produk.

Authors: PAYDAŞ Esma
Published: March 2019

Bu çalışma, silajlık

mısıra farklı seviyelerde Antep fıstığı (Pistaca

vera L.) dış kabuğu ilavesinin silaj kalitesi ile in vitro metan üretimi (CH4), in vitro organik madde sindirimi (İVOMS) ve metabolik enerji (ME)

içeriği üzerine etkilerini araştırmak amacıyla yapılmıştır. Bu amaçla, kontrol

mısır silajı katkısız grubu oluştururken; %3 ,%6, %9, %12 ve %15 düzeylerinde Antep

fıstığı kabuğu içeren silajlar katkılı grupları oluşturdular ve tüm silajlar

1.5 L cam kavanozlarda 5’er tekerrür olacak şekilde hazırlandı. Katkısız grup

ile kıyaslandığında, Antep fıstığı kabuğunun seviyesinin artışına bağlı olarak in vitro CH4 gazı oluşumunda

azalma (P=0.012) görülmüştür. Antep fıstığı kabuğu ilavesi ile hazırlanan

silajların silaj amonyak azotu (NH3-N), asetik asit, propiyonik asit

ve laktik asit içeriklerinin azaldığı görülmüştür. Bu çalışmada %6, %9, %12 ve

%15 düzeyinde Antep fıstığı kabuğu ilavesi ile hazırlanan silajlarda bütirik

asit tespit edilmemiştir (P=0.000). Sonuç olarak gıda endüstrisi yan ürünü olan

Antep fıstığı kabuğunun silajlık mısır bitkisine %9 oranında ilave edilerek

birlikte silolanabileceği ve ruminal metan gazı üretimini azaltabileceği tespit

edilmiştir. Antep fıstığı kabuğunun yem tüketimi ile hayvansal üretim ve

performansa etkisinin tam olarak ortaya konabilmesi açısından bundan sonraki

çalışmalarda in vivo hayvan

denemelerinin yapılması gerektiği kanaatine varılmıştır.
Kuluçka Sonrası İlk İki Haftada Lipopolisakkarit Uygulanan ve Uygulanmayan Broyler Civcivlerde Dalağın Histolojik Gelişimi
Authors: EREN Ülker
Published: March 2019

Civcivlerde aşılama, adaptif immunitenin geliştirilmesini amaçlar.

Dalak, lenf düğümü olmayan tavuklarda, adaptif immunite açısından oldukça

önemli role sahiptir. Sunulan çalışmada, broyler civcivlerde dalağın

gelişiminin, antijenle uyarılmış ve uyarılmamış gruplarda araştırılması

amaçlandı. Materyal

olarak 225 adet Ross 308 ticari broyler civciv kullanıldı. Civcivler 1, 4, 7,

10, 14 günlük olmak üzere her biri 45’er adet civciv içeren beş ana gruba

ayrıldı. Her grup kendi içinde kontrol, lipopolisakkarit (LPS) ve PBS solusyonu

uygulanan olmak üzere üç alt gruba ayrıldı. Antijenik uyarım LPS’nin

intra-abdominal uygulaması ile gerçekleştirildi. Uygulamadan 1, 3, 6, 12 ve 24

saat sonra üçer hayvandan dalak örneği alındı. Örnekler üçlü boyama, Gordon ve

Sweet’in gümüşleme metodu ve orsein-giemsa yöntemleriyle boyandı. Dalağın stroma ve parenşim kısımlarının gelişimi incelendi. Peri-ellipsoidal lenfoid doku

(PEL) bölgelerinin, bir günlük civcivlerde gelişmemiş olduğu gözlendi. PEL’de

dört günlük örneklerde tek tük lenfosit görülürken, ancak yedi günden itibaren

lenfosit kümeleri ayırt edildi. Literatürden

farklı olarak, subcapsular lenfoid doku (SCL) alanları tespit edildi.

Periarteriolar lymphoid tissue (PAL), perivenous lenfoid doku (PVL) ve SCL

kısımlarının lenfosit içerdiklerinin PEL’den daha yoğun olduğu görüldü.

Germinal merkez (GC) yapısının bir günlükten itibaren taslak halinde olduğu,

dördüncü günden itibaren retikulum iplikleri ile sınırlandırıldığı ve iki

haftanın sonunda gelişimini tamamladığı belirlendi. GC’nin de dalağın beyaz

pulpasına ait sabit bir yapı olduğu düşünüldü. Granulopoezis en yoğun olarak

bir günlük civcivlerde belirlendi. Antijenik uyarım yapılan ve yapılmayan

örneklerde, beyaz ve kırmızı pulpa açısından histolojik bir farklılık

gözlenmedi. Araştırma sonunda, broyler dalağında adaptif immunitede görev alan

kısımların, iki haftadan önce histolojik gelişimini tamamlamamış olduğu tespit

edildi.

Designing and presenting a destination as a tourist product is a process, which is influenced by different issues. Among them are perceptions of destination and attitudes towards a destination. In this study we have examined how media representation of destination safety and security affects attitudes about tourism destinations. Safety and security are important questions in the field of tourism and therefore we initially present
differing aspects of this topic. This research question was addressed as an experiment among students of tourism, who are future tourism product designers. The independent variable was the projection of terrorist attack films on observed destinations. The experiment used different questionnaires – among them was a nonverbal semantic differential. The results of these questionnaires showed that the perception of different destinations is lower than before the experiment and therefore that the safety and security issues are important factors when designing a tourist product
Funding patterns of bibliometrics research
Authors: Kokol Peter
Published: March 2019

To identify research funding patterns behind bibliometrics as a rapidly expanding science was the aim of the study presented in this paper. We analysed funding information of 8,622 bibliometric papers harvested from Web of Science, among which 1,786 (20.7%) were Papers with Reported Funding (PRFs). The trend in number of PRFs funding in last five years was positive. The most productive countries in PRFs` production were China, the USA and the UK. The same countries were also the most prolific regarding how many times they were mentioned in funding acknowledgements. The number of PRFs published per country was related with OECD reported Gross Domestic Spending on R&D for 2015. There was a significant correlation between number of PRFs per country and the number of all bibliometric papers per country. Far the most prolific funding agency was National Natural Science Foundation of China, followed by the European Commission and the USAs National Science Foundation. The Research trend and direction prediction is the most prolific research theme regarding the percent of PRF and thus most likely to get funded
