Authors: Asif Khan Muhammad , Ishfaq Umbreen
Published: February 2019

Writing is one of the basic language skills. Both objective tests and essay questions can be used to evaluate students’ performance in the writing skill. The objective tests are generally considered useful as they help in measuring certain abilities accurately and they yield reliable scores. But essay tests can be used more effectively to measure certain complex learning outcomes such as organization, synthesis, and analysis. Essays provide an effective form of testing to evaluate the communicative skill of students at the higher level. Such items have the problems of consistency, objectivity, and reliability of their scores. The present study focuses on the issue of scorer reliability and attempts to suggest an objective model of scoring for the free-response essay question set in the B.A. examination for Islamia University of Bahawalpur in the subject of English compulsory.

Authors: Ali Akbar , Khan Bilal , Awan Nazakat
Published: February 2019

The paper mainly focuses on the contrastive analysis of the use of English and Pashto adjectives. Contrastive Analysis hypothesis developed in the 20th century from the two renowned theories of language acquisition and linguistics i.e. behaviorism and structuralism. This hypothesis states that the major barriers in the second learning and acquisition process arise from the interference of the first language. Contrastive analysis between languages facilitate the linguists and language teachers in predicting the difficulties a learner may confront through a structural, scientific analysis of pairs of languages (Brown, 2007). The adjectives of English and Pashto have been compared in the paper using contrastive analysis approach. The study finds that there are certain similarities and differences in the use of adjectives in English and Pashto which can cause issues in learning English adjective use by L1 Pashto speakers as ESL learners.

Published: February 2019

English Language Teaching has become a compulsory subject in the curricula of many developing countries. There has been an increase in the trend of skeptic viewing of the credibility of this subject for teaching only a language and not its ideology and culture. Studies show that under the impact of ELT learners develop a positive attitude to English culture and depreciation of the indigenous one. Same is the case in Pakistan. English ideologies and cultural representation were uncovered through the application of CDA. The main ideologies found in these books were superiority of “Us/Self” and the inferiority of “Them/Other”. The paper present the source and target culture in their true perspective making the source culture part of esteem instead of the foreign culture.

Published: February 2019

Most orientalists are not only convinced that a thorough going adoption of western culture by the Muslim world is inevitable, but many of them are actively participating in the process of westernization to hasten its completion as a speedily as possible.|Paradoxically it seems to some of them, that the more they study Islam, the more fervently the felt compelled to prove that is was malicius and distorted.Based on the statements made by orientalists about Islamic teaching it is clear that they can not refute of Islam. The favourable theme of all their writing is that Islam must be abandoned on the premise that anything, revealed fourteen centuries ago is necessarily irrelevant for the technological civilization of today.Therefore they conclude, that if the Qur’an and Sunnah and the sacred Syariah that derives from these sources can not the be reconciled with the current fashionable philiosophies, then Islam must be false.Key word: Orientalist, Islam, Religion, Civilization.
NUR MUHAMMAD DALAM TRADISI SUFISME
Authors: Sahabudin H.
Published: February 2019

Nur Muhammad merupakan salah satu ajaran dalam tradisi sufisme yang dikembangkan pada mulanya oleh al-Hallaj; Ibn Arabi, al Jilli, al-Burhanpuri dan akhirnya al-Nabhani. Menurut Hallaj Nur Muhammad memiliki dua hakikat: 'qadimah' sebagai 'nur al-azali' yang menjadi sumber ilmu dan irfan serta sebagai titik tolak munculnya para nabi dan aulia Allah dan 'haditsah' merupakan eksistensi sebagai ibn Abdullah yang menjadi Nabi dan Rasul. Selanjutnya al­Nabhani juga berpendapat senada. Baginya Nur Muhamad bersumber dari Allah dan oleh karenanyaa ia bersifat 'qadim' sedangkan Nur Muhammad adalah sumber segala makhluk dan oleh karenanya bersifat 'huduts'. Melalui huduts inilah Nur Muhammad bisa bersentuhan langsung dengan makhluk. la juga menjadi penghubung antara Allah dengan hamba-Nya. Selanjutnya, hamba bisa berdialog langsung dengan TuhanNya melalui shalat. Shalat adalah identik dengan bacaan dan dialog antara hamba denganTuhanNya melalui rukun kauli, fi'li dan qalbi. Untuk bisa mengungkap esensi bacaan dan dialog tersebut hanya mungkin bisa diperoleh melalui Nur. Nur tersebut berasal dari Nur Muhammad. Dengan demikian ada persamaan antara Nur Muhammad dengan fungsi shalat, yakni penghubung hamba dengan Allah SWT.Kata Kunci: Syekh Yusuf al-Nabhani, Nur Muhammad, Tasawuf, Wasithah.

Di antara karakteristik tersebut misalnya adalah kosa kata yang kebanyakan berasal dari tiga huruf, perubahan bentuk kata kerja sesuai dengan perubahan bentuk waktu (tenses), bentuk kata benda (ism) dan kata kerja (fi'il) serta penggunaan kata ganti (dhamir). Di samping itu, antara bahasa Arab dan bahasa  Semit, terclapat pula kesamaan dalam susunan dan bentuk kalimat serta banyak kosa kata.Mengingat kaitan yang demikian erat antara bahasa Arab dan rumpun bahasa Semit, maka studi tentang bahasa-bahasa Semit menjadi sangat relevan bagi para peneliti bahasa Arab.Sebelum  mengurai   hubungan   antara   al-Qur'an   dengan   bahasa Arab, penulis mengangkat permasalahan di sekitar asal-usul dan sejarah pertumbuhan bahasa Arab sejak dari awal kelahirannya yang masih dipenuhi kabut misteri hingga bahasa ini mencapai kematangannya yang luar biasa pada masa menjelang kedatangan Islam di jazirah Arabia.Kehadiran Islam dengan membawa al-Qur'an yang berbahasa Arab sebagai mukjizat, temyata membawa pengaruh yang sangat besar bagi bahasa Arab sehingga bahasa ini masih tetap eksis dan bahkan terus berkembang sampai sekarang.Kata Kunci: Bahasa Semit, bahasa Arab, al-Arab al-Baidah, al-Arab af­ Baqryah.
SISTEM EKONOMI KAPITALIS, SOSIAL DAN ISLAM
Authors: Masykuroh Nihayatul
Published: February 2019

Sampai tahun 50-an, dunia hanya dipengaruhi oleh pertentangan idiologi antara Kapitalisme di satu pihak dan komunisme di pihak lain. Kedua kubu, dengan pertentangan mati-matian berpangkal pada satu falsafah hidup yang dinamakan materialisme (falsafah kebendaan). Seolah-olah manusia melupakan bahwa di balik materi yang diperjuangkannya, masih ada kekuatan gaibyang harus diyakini dan ditakuti yaitu Tuhan Yang Maha Esa.

Islam membawa falsafah tentang harta dunia yang menguasai sebagian faham manusia di dunia, yaitu falsafah ketuhanan. Falsafah ini berbeda sekali dari paham universalisme dari gereja pada abad pertengahan yang lalu dan juga faham idealisme yang bisa diartikan orang. Salah satu sumbangan terbesar Islam kepada umat manusia adalah prinsip keadilan dan pelaksanaannya dalam setiap aspek kehidupan manusia, dimana setiap anggota masyarakat didorong untuk memperbaiki kehidupan material masyarakat, disamping berusaha untuk memperbaiki kehidupan rohani dan mengingatkan setiap benda di dunia untuk diambil manfaatnya, tetapi secara bersamaan ·Islam mendidik mereka bertanggung jawab, bukan saja kepada istri dan keluarganya, tetapi juga terhadap saudara-saudaranya, yang miskin dan melarat, negara dan akhirnya seluruh makhluk.

seluruh aspek kehidupan, walaupun prinsip keadilan ini menyentuh setiap individu, namun yang paling penting adalah akibat yang ditimbulkannya terhadap kehidupan sosial persoalan keadilan ini akan lebih jelas lagi bila ia dikaitkan dengan aspek ekonomi. Ketiga aspek dimaksud yaitu: aspek kepemilikan, aspek konsumsi dan aspek distribusi pendapatan. Dari ketiga aspek ini, nanti dapat terlihat persamaan maupun perbedaan pandangan dari ketiga sistem ekonomi dalam memandang ketiga aspek kehidupan di bidang ekonomi.

Kata Kunci : Sistem Ekonomi Kapitalis, Sistem Ekonomi Sosialis, Sistem ekonomi Islam, Falsafah Matenalisme.

The impact of
privatisation process on business performance of the selected companies in the
Republic of Croatia
Authors: Vuković Dijana , Mamić Sačer Ivana
Published: February 2019

Privatisation processes have begun in the last decades of last century. Many countries recognized the advantages of privatisation in the form of financial goals such as increasing state budget, lowering indebtedness and strengthening market economy. Furthermore, the presumption of privatisation is that private ownership is better for achieving higher profitability of a company. Financial statements are common expression tools for companies’ business performance and financial position. Since accounting information system is a system where business events should be recorded, main output of the system are basic financial statements. The main goal of this study was to investigate the impact of privatisation process on business performance on the example of the selected companies in the Republic of Croatia. For the purpose of the study, the theoretical analysis of privatisation effects on business performance was made. Other than that, the empirical analysis of the selected companies in Croatia was conducted. This analysis was performed in two ways. First, the analysis of the selected financial ratios before and after the privatisation process was done through quartile analysis. The observed financial ratios were gross profit margin, ROA, ROE, total assets turnover and total economy ratio. To gain the individual impact of the privatisation process a deeper analysis of the selected ratios was conducted on the same research sample. Research results based on quartile analysis indicated that there is a difference between profitability prior and after privatisation and the privatized companies are more successful than the observed state-owned companies. However, based on the individual analysis’ research results the hypothesis that privately owned companies are more successful than the state-owned companies is only partially confirmed.

Authors: Bobok I. , Kobozeva A. , Maksymov M. , Maksymova O.
Published: February 2019

Video surveillance has become an important constituent part of the integrated security system of nuclear power plants. Due to this, the integrity and authenticity of the video transmitted by the surveillance camera are extremely important, and so is the possibility to identify violations of these categories of information in real time.

The authors propose a new method to detect one way of violating the integrity of the video sequence — “camera loop” hijacking. The proposed method based on identifying the perturbation in matrix of the current frame of the original video sequence in transition to the next frame ensures the efficiency of the method that is not dependent on the specifics and characteristics of the analyzed video sequence. The high efficiency of the method is confirmed by results of a computational experiment, under which type I and type II errors were not found. The practical value of the proposed method is the possibility of its work in real time because it is a polynomial of degree 1, as well as the simplicity and multiplatform implementation.

Authors: Mirzov I. , Kandala S.
Published: February 2019

Ukraine currently does not have a company to perform full neutronic calculations of VVER-1000 core. In this regard, the paper proposes a method of parametric assignment of volumetric heating due to gamma-radiation and the irradiation dose rate in VVER-1000 core baffle. The method significantly simplifies assessment of the stationary temperature, irradiation swelling and stress-strain state of pressure vessel internals. The method is based on the approximation of the input fields by polynomial s of nth degree in the radial and circumferential coordinates. Methodical error in the calculation of the stationary temperature field is 3,2 %, 12,7 % — in the calculation of radiation swelling, 33,0 % — in the evaluation of radial deformations of the core baffle. This allows to use the method for the preliminary assessment of technical condition of the VVER-1000 reactor internals.

Authors: Gerliga V. , Kravchenko V. , Prityka I. , Ghanem Hussam
Published: February 2019

The paper presents the technology of industrial waste purification based on the use of natural mineral bentonite sorbent with a large specific surface area, achieved by a cavitation crushing method, partially up to nanosize particles. The possibility for the purification of liquid radioactive waste (LRW) is shown by the example of floor drains with a significant content of salts, as well as organic mineral oils and surface-active substances. In addition to sorption of radionuclides, the used nanostructured sorbent has the ability to sorb heavy metals, salts, borates.

The proposed technology contains several stages: ultrasonic treatment of ozonized LRW with the addition of sorbent; centrifugation or precipitation of the resulting mixture; obtaining a sorption-crystalline precipitate and condensate by evaporation. The final stage of processing — evaporation and vitrification in detail in this paper are not considered.

The research presents the method of purification of actual LRW solutions for subsequent treatment with sorption-crystalline concentrate for vitrification. Coefficient of activity decrease equals to 103. The cost of technology is negligible, because it is based on the use of cheap bentonite. The proposed method can be used also for cleaning general industrial waste.

The this work all investigations are carried out for the storage containers of spent nuclear fuel of WWER-1000 reactors, which are operated in the Dry Spent Nuclear Fuel Storage Facility in Zaporizhska NPP. The analysis of existing investigations in the world nuclear engineering science concerning to the prediction of maximum temperatures in spent nuclear fuel storage container is carried out. The absence of studies in this field is detected and the necessity of the dependence for the maximum temperature in the storage container and temperature of cooling air on the exit of ventilation duct from variated temperatures of atmospheric air and decay heat formulation is pointed out. With usage of numerical simulation by solving of the conjugate heat transfer problems, the dependence of maximum temperatures in storage container with spent nuclear fuel from atmospheric temperature and decay heat is detected. The verification of used calculation method by comparison of measured air temperature on exit of ventilation channels and calculated temperature of cooling air was carried out. By regression analysis of numerical results of studies the dependence of ventilation air temperature from the temperature of atmospheric air and the decay heat of spent nuclear fuel was formulated. For the obtained dependence the statistical analysis was carried out and confidence interval with 95% of confidence is calculated. The obtained dependences are expediently to use under maximum temperature level estimation at specified operation conditions of spent nuclear fuel storage containers and for the control of correctness of thermal monitoring system work.

The paper deals with the estimation of the residual strength of the body of water jet pump SN-10 /50K type operating in the beyond design lifetime in the line of NPP unit sprinkler pumps. The results of theoretical studies of its stressed-strained state are presented taking into account change in the geometry of body parts, which was observed after completion of the design lifetime. Static strength assessment was carried out for the main operating modes of the pump operation (normal operating conditions and hydraulic tests), as well as for conditions of an emergency situation. Corresponding researches were carried out in the framework of numerical computer simulation on the basis of the finite element method using up-to-date software complexes. 3D finite element models have been developed that take into account actual geometry of the pump components and the forecast of its possible change for a period of extended lifetime. The change in the design geometry is taken into account based on the extrapolation of the data of thickness measurement of the pump body walls obtained during the long service period. Based on the built finite-element models, the tasks of thermal conductivity and thermoelasticity have been consistently solved. The phenomenon of thermal shock on body parts was simulated that allow assessing residual pump strength in case of an emergency. Corresponding simulation was carried out by solving the problems of nonstationary thermal conductivity and the related problem of quasi-static thermoelasticity. Such an approach made it possible to determine the distribution of the temperature field over time under thermal shock, and the distribution of the stressed-strained state parameters of the pump at certain time moments.

Analysis of informational provision level of complex environmental monitoring system in surveillance zones of Ukrainian NPPs was carried out. It was established that different subsystems are used for solution of monitoring tasks. The systems are separated, heterogeneous, hardware-software incompatible, and aimed at observation and state assessment of specific components of the environment and natural resources. Such situation is not in compliance with the up-to-date European requirements and standards for environmental monitoring information systems in areas of influence of man-made facilities. It is demonstrated that solution of this problem is possible by developing an information and analytical expert system for evaluation of NPP environmental impact on the environment (EcoIES). The main tasks that will be solved by EcoIES and its specific functions during emergencies or corresponding emergency exercises were described. The main requirements for the system are consistency, openness, standardization and adaptation. Specific requirements are the completeness and hierarchy of information, comprehensive integration and rational use, semantic unity, compatibility of system components, integrated security. Three options of conceptual approaches to creation of EcoIES have been developed, each of which is characterized by its structure, level of hardware-software provision and organization of information exchange. The option, which to major extent is in compliance with the European requirements has been substantiated, and which allows to fully solve radiation and environmental safety tasks, as well as civil protection of population, territories and the environment in the surveillance zones of Ukrainian NPPs. Therefore, this approach is recommended for further practical implementation at NPPs in Ukraine. The basic scheme of structural organization and interconnections between the EcoIES and other subjects of environmental monitoring that are part of the State environmental monitoring system has been developed.

The safety of fuel loading of VVER reactors is justified by calculations of the neutronic characteristics of the forthcoming campaign. These calculations are based on the design parameters of fuel assemblies (FA) — fuel enrichment, materials, design features, etc. However, during operation, some parameters change in an uncontrolled manner. In particular, FA can deform — bend or twist, this leads to the appearance of increased gaps between the fuel assemblies. These regions filled with a moderator lead to an increase in comparison with the calculations for the generation of thermal neutrons and, as a result, to a surge in the power of the fuel rods surrounding these regions. Safety requirements limit the power of fuel rods. Therefore, design capacities are increased by means of the so-called engineering margin factor to account for random outbursts. The deviation of the size of the water gaps between the fuel assemblies from the design ones should be known to calculate this coefficient, for example, the size distribution function of the gaps. This information is most often obtained by modeling the mechanical state of fuel assemblies in the reactor core. Other approaches are based on experimental data. Measurements in the core during the campaign are not possible. Therefore, the geometric parameters of the fuel assembly after the discharging from the core are measured. The presented paper uses the data of such measurements obtained after the 24th fuel campaign of ZNPP unit 4.

It is assumed that the fuel assemblies tend to retain the form they have in the “free” state, and mechanical interaction with neighboring fuel assemblies leads to a certain equilibrium state that can be easily analyzed. In contrast to similar calculations, the elastic energy functional of interacting fuel assemblies is proposed whose minimum gives the required size distribution function of the gaps. 24 and 25 campaigns were modelled; the role of inter-sector FA shuffling was studied.

The distribution of the gaps between the fuel assemblies in VVER-1000 core is calculated based on the measured deformations of the fuel assemblies discharged from the core and the elastic characteristics of the fuel assemblies. It was demonstrated that 95 % of gaps in the cores both with FA-A and FA-WR do not exceed 7.6 mm. The results can be used to calculate the engineering margin factor in determining the peaking factors of energy release.
