Published: October 2019

Целью настоящего исследования является оценка хладостойкости металлов с различным типом кристаллического строения, применяемых для изготовления конструкций и узлов, эксплуатирующихся в широком диапазоне низких температур.Для решения поставленной цели проведены испытания на ударный изгиб исследуемых металлов в диапазоне температур климатического холода с последующим исследованием изломов металлов.Исследования проводились с использованием методов оптической и электронной микроскопии, фрактографических исследований и рентгеноструктурного анализа. В ходе исследования получены данные по изменению ударной вязкости, механизмам разрушения металлов для широкого диапазона низких температур, а также температуре вязкохрупкого перехода и параметру кристаллической решетки исследуемых металлов.Установлено, что материалы с ГЦК- и ГПУ-решеткой проявляют бόльшую сопротивляемость разрушению при низких температурах и имеют, как правило, больший параметр кристаллической решетки по сравнению с металлами с ОЦК-решеткой. Вязкохрупкий переход в рассматриваемом диапазоне температур наблюдается только для металлов с ОЦК-решеткой. Металлы с низким содержанием углерода проявляют бόльшую сопротивляемость разрушению при ударных нагрузках, и температура вязкохрупкого перехода для таких сталей ниже.

Fabrication and characterization of nanoporous anodic alumina membrane using commercial pure aluminium to remove coliform bacteria from wastewater
Authors: Aghili Hamed , Hashemi Babak , Bahrololoom Mohammad , Jahromi Seyed
Published: October 2019

Nanoporous anodic alumina (NAA) membranes were produced by anodizing process
using commercially pure aluminium (1050 alloy). The optimization of
processing parameters, such as applied potential, temperature and time in
two different electrolyte solutions, has been performed to produce the
ordered alumina nano-membrane. Nanoporous anodic alumina membrane (NAAM) was
obtained by removing the aluminium substrate and opening the bottom of the
pores. The microstructure of samples was studied and analysed by field
emission scanning electron microscopy (FESEM). Image processing of FESEM
pictures was performed with MATLAB. The results showed that at the optimum
conditions of anodizing, the percentage of porosity and ordering of pores in
the samples were similar to the productions of the high purity aluminium
base. NAA layers that formed in sulphuric acid solution in comparison with
oxalic acid had lower pore diameter (20 nm), lower inter-pore distance
(45-50 nm) and higher hardness (325HV). The optimized membranes which have
been produced with the same thickness were used for separation of Coliform
bacteria from the secondary clarified wastewater. The results showed that
these membranes can be used as selective filters because of their desirable
physical properties.
3D printing of kaolinite clay with small additions of lime, fly ash and talc ceramic powders
Authors: Revelo Carlos , Colorado Henry
Published: October 2019

Direct ink writing technique, an extrusion based additive manufacturing
process, has been used to fabricate kaolinite clay based-ceramics with
several inexpensive ceramic powders: lime, fly ash and talc. All the above
materials are commonly used in the traditional ceramics industry, in both
small and large industries, and therefore available worldwide. This research
shows the simplicity of the process feasible not only for companies but also
for individual users. The samples were fabricated with water to clay ratios
(W/C) between 0.68 and 0.72. Additives were tested in 3.0, 5.0 and 7.0wt.%
with respect to the clay contents, although 3 wt.% of additives worked best.
Cylindrical samples were fabricated with 20mm in diameter and 20mm in height
in order to test their compressive strength and density. Measurement samples
were previously cured for three days at room temperature and then exposed to
1100?C for 1 h. The powdered additives and their corresponding mixtures
with clay were characterized with scanning electron microscopy, X-ray
fluorescence and X-ray diffraction techniques. Results showed that samples
with 0.70 W/C ratio and using fly ash as an additive were the best in terms
of workability, mechanical properties and surface finishing.

Background/Aim. Thyroid nodules represent a common problem in medicine. Ultrasound examination of the thyroid glands is a common method for the initial diagnosis of thyroid neoplasia enabling the selection of nodules that should undergo fine needle aspiration biopsy (FNAB). It is a noninvasive method that has a great potential in discovering suspicious lesions, enabling timely actions for further diagnostics and potential treatment. However, it is still not clear enough how the quantitative data collected from Ultrasound elastography correlate with those obtained by other diagnostic tools used for detecting thyroid nodules. The aim of this study was to estimate the importance of ultrasound elastography in diagnostics of differentiated thyroid carcinomas but also to estimate the importance of other diagnostic procedures as well. Methods. The research was performed on patients initially referred to the Clinic of Endocrinology in Military Medical Academy, Belgrade to evaluate the status of thyroid nodules. The da-ta from ultrasound elastography was then correlated with those from other diagnostic procedures including clinical examination, echosonography, cytological and histopathological analyses. Results. Statistically significant difference between the group of patients with follicular adenoma and the group of patients with differentiated thyroid carcinoma was detected for consistency, nodules immovability, thyroglobulin (Tg) levels, presence of calcifications in the nodules and the elastographic score. Fixed nodules and those with firmer consistency were significantly more common in the group of patients with malignant lesions, in which Tg levels were higher. The elastography score 3-4 showed a high predictive value for the detection of thyroid carcinoma, unlike the elasticity score. Conclusion. Ultrasound elastography represents a new non-invasive method that has a very significant, high predictive value for the detection of thyroid carcinoma, especially in correlation with other diagnostic procedures.

Fascioliasis is one of the oldest zoonotic infestations, which returned back to 3000 years B.C., it is caused by Fasciola hepatica or gigantica. It is a widespread disease throughout the world; nearly (2.4 – 17) millions of people is infected. Human is an accidental final host by ingestion of contaminated plants and water by metacircaria. Most of patients suffer from right upper abdominal pain with eosinophilia. Diagnosis is made on clinical background with imaging studies or laboratory (like stool and examinations biliary aspirate, intradermal test or ELISA to detect antibody). It must be taken into consideration as newly emerging infestation in our country. The aim of this study is to highlight on the magnitude of Peri Cholecystectomy Bile Analysis for Fasciola hepatica in Sulaimani province, Kurdistan region and even in Iraq as a whole. A prospective study was performed at Sulaimani Teaching Hospital. Bile samples were collected from who had cholecystectomy. Microscopical analysis was archived for finding egg of the parasite. In 129 samples, there were 7 (5.4%) positive cases of Fasciola hepatica 2 were adult worms, all were swimming in the gall bladder. 5 (3.9%) out of 7 (5.4%) samples were females and only 2 (1.5%) of cases were males.  4 (3.1%) out of 7 were from Sharazur terrain, and 3 (2.3%) of them from the center of Sulaimani city.  Fascioliasis is a zoonotic problem. It must be put in differential diagnosis of any vague upper abdominal pain. It is a public health issue, so health worker must give awareness to the society about this disease, which is more easily preventable.
The System Of Monarchical Government In Modern World And Its Features
Authors:   Saratov State Vavilov Agrarian University, Fedorova-Kuznetsova Irina Vladimirovna
Published: October 2019

The form of government of any state is directly de-termined by the essence of the state and the form of organizing the state power, its internal circumstanc-es. Under a monarchical government, the head of the state is always the monarch. And the form of the monarchy is completely irrelevant whether it is abso-lute or constitutional (limited). Monarchy is charac-terized, first of all, by monocracy, i.e. belonging of state power to the single person – the monarch, and hereditary way of transferring power from one mon-arch to another. At the same time, it should be noted that the monarchical institutions have undergone a long political evolution and serious modernization resulting in later modifications. The main purpose of our study is to identify the main features of present-day monarchies which in large part distinguish them from historical prototypes.
Information Countermeasures To Religious Extremism In The Light Of Ensuring National Security (As Exemplified By The Northern Caucasus)
Authors:   Dagestan Federal Scientific Center of the Russian Academy of Sciences, Magomedova Muslimat Alkhilayevna
Published: October 2019

The article deals with peculiarities of manifestation of religious extremism as one of the threats to the Russian Federation national security. There are iden-tified new tendencies in countering religious extrem-ism, inclu-ding the ones on the part of civil society institutions, public policy structures, expert com-munity and mass media. It is as well noted that de-spite the reduction of the number of terrorist acts in the Northern Caucasus, there is still a threat of the spread of radical religious ideology in the region. The article covers peculiarities of jihad interpretation by different Islam branches. It also points to the fact that jihad is often misinterpreted in mass media sources. Based on the identified causes and factors of the spread of radical ideology among young peo-ple and the evaluation of effectiveness of the con-ducted information policy the article provides re-commendations on countering religious extremism in mass media and social networks. The author con-cludes that it is necessary to develop an alternative anti-terro-rist content, which can be actively used in mass media and in the Internet and thus will help to unmask the ideology of extremism and provide for its rejection on the part of the youth.

Sociological Barriers in the Quality of Production
Authors: Suchacka Małgorzata , Horáková Nicole
Published: October 2019

In this article is drawn attention to the social aspects of improving the quality of production. The relationship between the development of technology and society is still underappreciated. There is a vital need to make technical managers aware of the rules governing interpersonal relationships. This theoretical article aims to bring the basic concepts of social sciences closer to recipients focused on constant improvement of the production quality. The essence of the work process is primarily the fact that it is done by a human being and mostly in a group of people. This is related to the consequences of sociological nature to which managers do not pay enough attention. Instead of focusing on social and interpersonal problems they are dealing with organizational issues. The conclusion of consideration leads to underlining the need for constant improvement - manager training in social engineering principles.

Authors: Belan Juraj , Kuchariková Lenka , Mazur Magdalena , Tillová Eva , Hanusová Patrícia
Published: October 2019

The Ni-base superalloys are used in the aircraft industry for the production of aero engine most stressed parts, turbine blades or turbine discs. Quality of aero jet engine components has a significant influence on the overall lifetime of a jet engine as itself as well as the whole airplane. From this reason a dendrite arm spacing, grain size, morphology, number and value of γ′-phase are very important structural characteristics for blade or discs lifetime prediction. The methods of quantitative metallography are very often used for evaluation of structural characteristics mentioned above. The high-temperature effect on structural characteristics and application of quantitative methods evaluation are presented in this paper. The two different groups of Ni-base alloys have been used as experimental material: cast alloys ZhS6K and IN713LC, which are used for small turbine blades production and wrought alloys EI 698VD and EI 929, which are used for turbine disc production. Selected alloys have been evaluated in the starting stage and after applied heat-treatment at 850°C for 24 hrs. This applied heat-treatment causes structural changes in all alloys groups. In cast alloy dendritic structure is degraded and gamma prime average size has grown what has a negative influence on turbine blade creep rupture life. Wrought alloys show partially grain boundary melting and grain size changed due to recrystallization what causes mechanical properties decreasing – ultimate tensile strength mainly.
Analysis of Technical Condition of Local Roads Drainage in the Czestochowa Region
Authors: Respondek Zbigniew
Published: October 2019

Local roads (district and municipal) play an important role in the road network, especially in rural areas. In recent years, these roads have been largely repaired, which was often associated with the construction of new infrastructure. One of the basic conditions of maintaining the quality of road works is the proper construction or renewal of drainage devices. Errors in this area result in lower durability of the road pavement. It is equally important to maintain these devices later in a good technical condition, which requires spending appropriate funds from local government budgets. The aim of the study presented in the article was to determine the current technical condition of drainage of local roads in the Czestochowa region and to identify the most frequent design and implementation errors, resulting in a rapid loss of functionality of drainage devices. They were based mainly on in situ studies carried out in the area of an exemplary rural municipality. Errors resulting in the lack of continuity of drainage, or the danger of a rapid loss of its functionality are shown with real examples. It was found that despite the shortcomings described, in recent years the technical condition of drainage of local roads has improved, which is related to the systematic overhaul of local roads (including the construction of sidewalks) and the local government's perception of the importance of road drainage problem.

Authors: Bobalo Taras , Blikharskyy Yaroslav , Krainskyi Pavlo , Volynets Myhailo
Published: October 2019

The use of computers provides the opportunity to analyse and design complex structures, taking into account the geometric and physical nonlinearity of construction materials. In the article the study of stress-strain state of mixed steel-concrete beams, were presented. The results of this study showed that the method of calculation according to designe codes gave satisfactorily results of calculated strength compared with experiments. However, these methodes do not provide complete information of structural performance at all levels of load. For a more complete study of the stress-strain state and the physical nature of the processes occurring in steel-concrete structures reinforced with a mixed reinforcement, the calculation method using “Lira” software complex is proposed. The method of calculation is based on the finite element method. The calculation is made taking into account physical nonlinearity and real diagrams of σ-ε of materials using the nonlinear deformation law №14 of “Lira” software complex. The proposed method of calculation allows to determine the values of bearing capacity, the development of deformations and the beginning of crack formation, as well as stresses at all load levels.
Corrosion of RC Beams During Time
Authors: Blikharskyy Yaroslav , Khmil Roman , Blikharskyy Zinoviy
Published: October 2019

This article presented results of impact corrosion on reinforce concrete beams during time with previous loading. Before testing the RC beams were loaded by 37% and 75% from bearing-capacity load of undamaged corrosion beams. There were tested two types of beams. First type beams were tested under force loading action and second type beams were tested under force loading and corrosion action. As an aggressive environment were used the 10% solution of sulfuric acid H2SO4. Such environment takes place in separate chemical manufactures, galvanic workshops, flue pipes of thermal power plants. The results of experimental studies have established that the effect of the aggressive environment with simultaneous loading significantly impairs the stress-strain state of reinforced concrete beams. Bearing capacity due to the yielding of reinforcement bars for specimens with the simultaneous action of aggressive environment and previous loading of 37% and 75% takes place on 51…53 and 58…60 days. The destruction of these specimens, by crushing compressive concrete, at previous loading 37% occurred after 75…79 and at previous loading 75% - after 79…88 days. The history loading does not impact significantly on beams failure, on finite deflections and timing exhaustion bearing capacity since the start of the simultaneous action of aggressive environment and loading.
Shape Optimization of a Column under Generalized Load with a Force Directed towards Positive Pole
Authors: Szmidla Janusz , Jurczyńska Anna
Published: October 2019

In this paper, the issue of shape optimization of a column subjected to the generalized load with a force directed towards the positive pole (L. Tomski’s load, specific load) was considered. Based on the Hamilton’s principle, the differential equations of movement and boundary conditions describing the system were formulated. Taking into account a kinetic criterion of stability loss and a condition of constant total volume, the scope of changes in natural frequency as a function of an external load was determined with selected geometrical and physical parameters of the loading structure. On the basis of obtained results, values of geometrical parameters of individual column segments were determined, at which the maximum critical load value was obtained. In order to find the maximum critical force, which is a function of many variables, the simulated annealing algorithm was used.

Authors: Vegera Pavlo , Khmil Roman , Vashkevych Rostyslav , Blickharskyy Zinoviy
Published: October 2019

Main parameters, which characterize shear strength, are crack distribution, width of diagonal crack opening and angle of inclined crack. There are in this article, comparison crack resistant of testing reinforced concrete (RC) beams on the shear with such variable parameters like presence or absence internal reinforcement, different shear span, and presence or absence external composite reinforcement. Shear span (relative span to effective depth ratio) was acquired the following values: a/d=2, 1.5, 1. For internal reinforcement, rebar’s A240C with diameter 8 mm and steps 100 mm was chosen. The composite FRCM system was like external reinforcement with three stripe of composite fabric with width 70 mm and step 100 mm. Eight RC beams were tested. After testing, we discovered that the most influenced on the serviceability capacity was shear span. Internal transverse reinforcing increased shear strength on the same level and it was independent from shear span and other factors. Only quantity of reinforcing determine level of increasing shear capacity. FRCM system is efficient strengthening system, which significant increase shear crack resistant for RC beams. External FRCM reinforcing increase shear crack resistance on the same percentage and independent from presence or absence internal reinforcement.

Authors: Orman Łukasz J. , Radek Norbert , Pietraszek Jacek , Gontarski Dariusz
Published: October 2019

The paper deals with the important issue of boiling heat transfer enhancement using mechanical treatment of the heater surface. The surface has been modified in such a way that microfins have been produced. The application of such a structure leads to highly increased heat fluxes in relation to the smooth surface as has been presented and discussed in the paper. The experiments including distilled water and ethyl alcohol on the horizontal copper samples of 3 cm diameter have been considered. The heat flux value of microfinned surface was even nine times higher than the heat flux dissipated from the smooth surface without any coating.

Quality of Video Games: Introduction to a Complex Issue
Authors: Sobociński Maciej D.
Published: October 2019

The video games industry is one of the fastest growing branches of industry, reaching revenues comparable to (or even surpassing, depending on the source) the 70 year older film industry. The growth was not free from turmoil, as the industry faced many disruptive changes, market crashes, fusions and takeovers. High development costs and fierce competition make video games a high-risk business. While it seems obvious that companies in such unstable environment should strive to achieve the highest quality of their products, the uniqueness, variety, complexity, and constant evolution of video games makes common definitions and models of quality difficult to apply. This article provides an overview of problems concerning the application of the term “quality”, it's frameworks and measurement methods to video games.

Evaluating map specifications for automated generalization of settlements and road networks in small-scale maps
Authors: Sielicka Karolina Maja , Karsznia Izabela
Published: October 2019

The presented research concerns the methodology for selecting settlements and road networks from 1:250 000 to 1:500 000 and 1:1 000 000 scales. The developed methodology is based on the provisions of the Regulation of the Ministry of Interior from 17 November 2011. The correctness of the generalization principles contained in the Regulation has not yet been verified. Thus this paper aims to fulfil this gap by evaluating map specifications concerning settlement and road network generalizations.

The goal was to automate the selection process by using formalized cartographic knowledge. The selection operators and their parameters were developed and implemented in the form of a generalization model. The input data was the General Geographic Object Database (GGOD), whose detail level corresponds to 1:250 000 scale. The presented research is in line with works on the automation of GGOD generalization performed by the National Mapping Agency (NMA) in Poland (GUGiK). The paper makes the following contributions. First, the selection methodology contained in the Regulation was formalised and presented in the form of a knowledge base. Second, the models for the generalization process were developed. The developed methodology was evaluated by generalizing the settlements and roads in the test area. The results of the settlement and road network generalization for both 1:500 000 and 1:1 000 000 detail levels were compared with the maps designed manually by experienced cartographers.

Published: October 2019

Penelitian ini ingin menjawab faktor apa saja yang meleatarbelakangi tidak terlaksananya ‘uqubat restitusi, serta upaya yang dapat dilakukan untuk memperoleh hak restitusi terhadap korban perkosaan. Selama tahun 2018, wilayah hukum Mahkamah Syar’iyah Jantho yang menanggani kasus perkosaan tidak pernah menerapkan uqubat restitusi terhadap pelaku perkosaan. Penelitian ini menggunakan pendekatan yuridis empiris, lokasi penelitian di wilayah hukum Mahkamah Syar’iyah Jantho. Hasil penelitian menunjukkan bahwa Qanun Jinayat telah menjamin pemberian hak kepada korban perkosaan. Hak restitusi terhadap korban perkosaan belum terlaksana disebabkan upaya dari korban sendiri tidak membuat laporan, pengaduan, dan pengakuan untuk ditinjaklanjuti oleh penegak hukum. Pada dasarnya upaya yang dapat dilakukan untuk mendapatkan restitusi bagi korban tindak pidana perkosaan adalah adanya pengakuan dari korban, yang menderita dan juga adanya dukungan dari pihak keluarga atau masyarakat yang partisipasi terhadap korban sehingga mengajukan permohonan kepada yang berwajib untuk menjalani proses selanjutnya dengan tujuan agar terpenuhi hak korban. The Implementation of ‘Uqubat Restitution to Rape Victim This research wants to answer what factors are the underlying that have not been implemented the ‘uqubat restitution’, and the efforts to obtain restitution rights for rape victims. During 2018, the Jantho jurisdiction of the Syar'iyah Court never applied the restitutionary sentence to rape perpetrators. This study uses an empirical juridical approach, the location of the study is in the Jantho Jurisdiction of the Syar'iyah Court. The results showed that Qanun Jinayat had guaranteed granting rights to rape victims. The right to restitution of rape victims has not been realized due to the efforts of the victims themselves not to make reports, complaints, and confessions to be followed up by law enforcement. Basically, efforts that can be made to obtain restitution for victims are recognition of the victim and also support from the family or community so that the victim submits an application to the authorities to undergo legal proceedings in order to fulfill the victims' rights.
