The Intellectual Tradition of Libertarian Islam and Its Relation to the Thought of the Islamic State in Iran
Authors: Chitforoush Sajjad , Kakadezfuli Ali
Published: February 2022

Liberal thought in Iran was based on contemporary political and social conditions that influenced Iranian thought. Also, this idea has benefited from some of the features of Iranian and Islamic political culture; therefore, it has been shown in a new form, called the tradition of freedom of Islam.  One of the most important manifestations of this tradition can be seen in the formation of political thought after the victory of the Islamic Revolution. The main question of this research, after explaining the idea of libertarian Islam in the form of an intellectual tradition, is how this idea has been effective in shaping the constitution and the nature of the political system in contemporary Iran. The results of this study show that the main issue of liberal thought in Iran was freedom of the public and restrictions on the duties of the government. In this regard, the original "non" has been absolutism. Thus, at the same time as the formation of the constitution after the victory of the Islamic Revolution, in spite of the inability to achieve complete power and the hegemony in the field of thought, it tried to prevent the widespread extension of the functions of the political system by ormulating restrictive laws of political power.

Features of the Development of the Saudi Realistic Story in the Second Half of the Twentieth Century
Authors: Saidova Nargiza Makhmudovna
Published: February 2022

This article examines the specific features of the formation of a realistic method of narration, as well as the beginning of the development of a realistic direction in a new type of fiction in Saudi literature. By means of the analysis, the features of the poetics of the Saudi realistic short story in the second half of the twentieth century are considered. The specific features of the formation of the realistic method of narration and the time intervals of its formation depend, in many ways, on the historical conditions in which artistic creativity develops in each society. National-historical circumstances also determine the uneven development of realism in different countries. In Egypt, near the Arabian Peninsula, the realistic method of narration began to take shape at the beginning of the first half of the twentieth century, when most of the Arabian States were not even covered by the educational movement. Already in the first collection of Muhammad Teymur - one of the founders of the short story genre in Egypt "What the eyes see" (1917-1918), the main features of realism are shown, "showing life in its contrasts". The beginning of the development of a realistic direction in the new type of fiction in Saudi literature was laid at the stage of Enlightenment. The struggle with the inherited old norms of life and consciousness for the authors of educational literature resulted in a protest against the forms of new oppression associated with the preservation and maintenance of medieval traditions and ideas in modern society, and, therefore, in many works of Saudi enlighteners, despite their inherent features of sentimentalism and romanticism, the beginnings of realistic trends can be traced.

Published: February 2022

The school’s learning history can form a nationalist attitude, or serve as a moral education for students or learners. Therefore, the history subject can be used as a tool to form a nationalist attitude through educational institutions or schools, which can be seen from the changes in the attitude of the history subject and the learning outcomes of students. The research method used is quantitative, the quasi-experimental method is adopted, and the research design is a non-equivalent design. The sampling method in this study is purposeful sampling. The data analysis technique used in this study is independent testing. According to the completed data analysis, the following conclusions can be drawn: The influence of iSpring suite learning media on students' learning interest can be seen from the calculation results of the independent sample test. The value of this sample is 0.000, which is less than the standard significance value, which is 0.005. This means that there is an influence between the post-experiment and post-control values, that is, the post-control value 61.03 and the post-experiment value 71.57, so H0 is rejected and H1 is accepted. In addition, there is a difference between the interest value between the control class and the experimental class, which is 6.54, where the interest value of the experimental class bigger than the control interest value, or it can be said that iSpring suite media is better than PowerPoint media. This is also supported by the advantages of this media, which can convey material through images, videos, music, animation, and media based on computer-based assessment questions.

Authors: Tyshkevich V.N.
Published: February 2022

The study introduces an algorithm and method for optimization of flat grinding modes for low-rigidity workpieces such as rings and prismatic rods. The proposed solution ensures the specified quality of the machined surface at the maximum process efficiency. The required flatness tolerance of the machined surface is provided at the second stage of optimization modes by limiting the value of the maximum elastic deformation. The variable parameters are the cutting forces, magnetic field attraction of the machine table, and the bending rigidity of the workpiece. The study introduces mathematical models to determine maximum elastic deformation of workpieces when fixing and machining, outlines the conditions for ensuring the required flatness tolerance of the machined workpiece surface, taking into account the maximum elastic deformation of the low rigidity workpiece under the influence of the magnetic field of the machine tool and the radial component of the cutting force.
Combined Method for Calculating the Average Flow Centrifugal Compressor Stage
Authors: Kalashnikov D.A. , Borisov Y.A. , Chernyshev A.V.
Published: February 2022

The paper focuses on the optimal centrifugal compressor stage design and introduces a new approach to it that implies replacing a physical experiment with a numerical one. The efficiency of this approach is due to numerical testing of a large number of different variants of the compressor stage geometry for the same gas-dynamic parameters. Within the approach, for calculating and optimizing the compressor stage parameters, we developed a combined method not having the most empirical components. Relying on this method, we propose methods for calculating the parameters and optimizing the geometry of the compressor stage.
Kiedy badacz jest tajnym agentem. O postrzeganiu niejawnej obserwacji uczestniczącej jako etycznie problematycznej, metodach badań ilościowych, zakulisowych wymiarach życia społecznego i ich związku ze wszystkim tym, o czym przed chwilą
Authors: Miszewski Kamil
Published: February 2022

Artykuł dotyka drażliwej etycznie kwestii, jaką jest stosowanie niejawnej obserwacji uczestniczącej. Czy zawsze musimy informować ludzi, że stali się obiektem badania, czy też w pewnych przypadkach lepiej będzie, gdy tego nie zrobimy? Badani, wiedząc o badaniach, mogą podświadomie i świadomie wpływać na ich wyniki. Czasem ten wpływ jest tak wielki, że całkowicie fałszuje rzeczywisty obraz badanej rzeczywistości. Czy nawet wówczas nie wolno nam badać niejawnie w obawie o naruszenie norm etycznych? I czy na pewno możemy powiedzieć, że sam fakt takiego niejawnego badania jest już naruszeniem norm etycznych?

Czy bardziej zależy to od tego, co zdecydujemy się z tak przeprowadzonych badań przedstawić światu? Ale i tu pojawia się problem: jeśli za nieetyczne uznać np. zdradzanie pikantnych szczegółów z życia prywatnego, w posiadanie których weszło się mimowolnie, które nie mają nic wspólnego z tematem badań, to czy na pewno za takowe można uznać przedstawienie urzędnika jako najzwyklejszą “czarną owcę”, co wyniki badań dobitnie pokazały, choć być może ich publikacja poważnie mu zaszkodzi?

Socjologia polska omija pola badawcze, które wymagałyby stawania twarzą w twarz z takimi dylematami, stąd, zdaniem niektórych (nielicznych) socjologów, zatraciła umiejętność rzetelnej oceny dzisiejszej, (po)transformacyjnej rzeczywistości, w której niejawność wydaje się podstawowym sposobem działania, a do badania której standardowe metody badawcze nie za bardzo przystają.

EMDR Therapy for Bilinguals: Utilizing Linguistic Diversity for Improved Therapeutic Success
Authors: Ateş-Barlas Alev
Published: February 2022

EMDR protocols, theories, and guides tend to presume or prescribe a monolinguistic approach. However, there are many bilinguals whose knowledge of a second language (L2) is sufficiently advanced to allow them to interact with EMDR therapists, but who might also possess memories encoded in a first language (L1), which is strategically useful in EMDR. The objectives of this clinical practice study were to (a) describe the real-world use of EMDR therapy in which the L1 of an EMDR recipient is selectively integrated into processing by a therapist who need not know the recipient’s L1 and (b) demonstrate an adaptation of the standard EMDR therapy protocol to support full resolution of memory material among clients with exposure to more than one language.

Dalam penelitian ini menggunakan aplikasi ATOLL untuk proses planning dengan tujuan untuk memperkirakan hasil sebelum dilakukan optimasi pada site tersebut, proses drive test digunakan untuk mengambil data setelah proses optmasi berupa data RSRP, SINR yang nantinya akan diolah dengan menggunakan aplikasi Genex, ProbeAssistant , dan MapInfo. Proses optimasi yang dilakukan diharapkan dapat mencapai target KPI yang telah ditentukan sebesar 70% dan dari hasil optimasi tersebut baik pada parameter RSRP dan parameter SINR telah mencapai target KPI sebesar 70% dengan 70,08% pada parameter RSRP dan 78,13 pada parameter SINR.

Abstract

Along with the development of the era, the use of cellular networks is increasing, with conditions from 2020 until now that many offices implement WFH (Work From Home), even in education until now there are still many who apply WFH, this has caused the demand for cellular network services in Indonesia to increase. especially in areas that have not been reached by the network service. The addition of sites in areas that have not been reached by the cellular network is a solution used to expand coverage, but the site needs an optimization process to improve the quality of the services to be provided, the optimization method that will be used is physical tunning. In this study using the ATOLL application for the planning process with the aim of estimating the results before optimization at the site, the drive test process is used to retrieve data after the optimization process in the form of RSRP, SINR data which will later be processed using the Genex, ProbeAssistant, and MapInfo applications. The optimization process carried out is expected to achieve the predetermined KPI target of 70% and from the optimization results both the RSRP parameter and the SINR parameter have reached the KPI target of 70% with 70.08% on the RSRP parameter and 78.13 on the SINR parameter.

Case:

Multifocal synchronous primary skeletal chondrosarcomas of an extremity are rarely reported. In this study, we report 2 such cases. The first case is a 32-year-old woman who presented with extensive right femoral and tibial diaphysis lesions. The second case is a 36-year-old woman with lesions in the left proximal humerus, the coracoid process of scapula and sternum. Both patients underwent limb salvage surgery and were disease-free at the 38- and 20-month follow-up.

Conclusion:

Athough rare, the possibility of multifocal chondrosarcoma should be kept in mind during the workup of a patient with chondrosarcoma.

Case:

A 45-year-old man presented with posttraumatic fracture-dislocation of T11/12 with neurological level T8 AIS A. Sensory level progressed to T4 in the next day morning. He underwent T10, T11, T12, and L1 percutaneous pedicle screw-rod fixation. Postoperatively, there was rapid worsening of his neurology and within 48 hours, he became tetraplegic with neurological level C2 with respiratory paralysis requiring mechanical ventilation. He died on the 14th postoperative day. Clinicoradiological findings were consistent with subacute posttraumatic ascending myelopathy (SPAM).

Conclusion:

Surgeons must be vigilant in days and weeks after spinal cord injury for early recognition and management of SPAM. Treatment guidelines are uncertain and yet to be developed.

Pengkajian di bidang perpustakaan dan informasi berperan penting dalam meningkatkan kinerja perpustakaan. Pusat Perpustakaan dan Penyebaran Teknologi Pertanian (PUSTAKA) merupakan perpustakaan khusus di lingkup Kementerian Pertanian. Koleksi yang disediakan khusus bidang pertanian dan bidang lain yang terkait dengan pertanian dalam berbagai jenis dan format. Pemustaka yang memanfaatkan PUSTAKA adalah peneliti, penyuluh, karyawan, pengambil kebijakan, pengamat bidang pertanian, mahasiswa, dan pelajar. Mereka menggunakan informasi dalam bentuk tercetak dan elektronik. Semakin berkembangnya era digital, perilaku pencarian informasi pemustaka berubah. Pengkajian ini bertujuan untuk mengetahui tujuan pemustaka mencari informasi di PUSTAKA, pemanfaatan sumber informasi, kesesuaian informasi yang diperoleh dengan kebutuhan informasi, kemutakhiran sumber informasi, dan kepuasan pemustaka Pengumpulan data dilakukan terhadap 86 responden melalui pengamatan di ruang baca dan wawancara terstruktur yang berpedoman pada kuesioner. Data dianalisis dengan perangkat lunak Statistical Package for Social Sciences (SPSS) versi 20.0. Hasil pengkajian menunjukkan bahwa sebagian besar pemustaka adalah pelajar dan mereka mencari informasi di PUSTAKA dengan tujuan untuk menyusun karya tulis ilmiah yang merupakan tugas dari sekolah. Sumber informasi tercetak lebih banyak digunakan dibandingkan media elektronis. Lebih dari separuh pemustaka yang datang ke PUSTAKA menyatakan sumber informasi yang digunakan memenuhi kebutuhan informasi mereka, mutakhir, dan penting. Mayoritas dari pemustaka menyatakan puas terhadap sumber informasi yang digunakan. Sementara lebih dari 20% pemustaka menyatakan sumber informasi yang digunakan belum sesuai dengan kebutuhan informasi, belum sepenuhnya mutakhir, dan belum memuaskan pemustaka. Oleh karena itu, PUSTAKA perlu melakukan evaluasi terhadap koleksi perpustakaan. Selain itu, perlu memerhatikan karakteristik pemustaka dan kebutuhan informasi dalam pengembangan koleksi.

Tulisan ini membahas literasi informasi pada disabilitas netra yang berkaitan erat dengan layanan buku Braille dan buku digital pada Perpustakaan Yayasan Mitra Netra. Penulisan ini dilatari oleh masih banyaknya anggapan bahwa kaum tunanetra tidak berhak mendapat informasi seperti manusia normal, terutama di Indonesia. Tujuan penulisan adalah untuk mendeskripsikan literasi informasi disabilitas netra melalui buku Braille dan buku digital yang diharapkan menjadi media informasi bagi kaum tunanetra. Kesimpulannya, dalam melakukan literasi informasi, kaum tunanetra juga memiliki hak yang sama dengan bukan tunanetra. Selain perpustakaan yang menyediakan buku Braille dan buku digital, masyarakat juga dapat berpartisipasi aktif membantu tunanetra dalam mengakses informasi untuk meningkatkan literasi informasi disabilitas netra.

We report the development of a model to support matrix-based stimulation treatments in limestone reservoirs that takes information directly from data obtained during core flooding, such that the model can be calibrated against a variety of novel stimulation fluids under conditions directly representative of the candidate field. The model builds on an earlier stimulation model developed for clastic reservoirs, which primarily addressed stimulation as a formation-damage-removal phenomenon; it maintains the 3-dimensional aspects of the earlier model but incorporates the substantially greater complexity required in coupling the damage-dissolution reactions to the hydrodynamic phenomena associated with the formation of wormholes. Wormholes are an ideal method of stimulating carbonate reservoirs (in the absence of massive hydraulic fracturing) but their formation is stochastic, anisotropic, and involves greater morphological changes. Hence, successful stimulation depends on formulation chemistry, application rates, rock morphology, pressure, and temperature. This initial model has been calibrated to describe the behaviour of a selection of non-standard stimulation fluids, which have been evaluated in part through core-flood performance. The reaction-rate data for these novel fluids was abstracted from a series of core flood experiments with effluent and morphological analyses. The user interface provides easy condition input and selection and provides a clear output of results. Future developments will expand the model to a broader range of conditions and chemical formulations.
New Single-Step Acidizing Technique Treats Severe Fines Damage Over a Wide Range of Temperatures and Mineralogies

Most sandstone reservoirs in shallow water continental shelf fields are fully mature and require economical low-risk stimulation treatments to achieve maximum recovery. The once characterized "New Fronter" developments in Deepwater and Ultra Deepwater are also entering the mature, end of life status. 2019 had the largest increase in acid stimulation treatments ever in the Deepwater Gulf of Mexico. This study focused on identifying a HF acid derivative treatment that could be used as a single-step sandstone acid treatment, with all the associated benefits, but would not require acid flowback services. Five commercially available buffered, retarded, and HF derivative acid chemistries were tested to determine the risks of facility upsets. Laboratory tests showed that these HF derivative acid chemistries had varying levels of potential facility upset risk in either viscous emulsion formation or overboard water quality noncompliance. A new Fluoroboric Acid (HBF4) chemistry was developed building on 80 years of well-known performance history. This chemistry has all the benefits of HBF4, is compatible with most sensitive minerals and does not cause facility upsets. Ninety-three treatments were done in the eastern and central US GOM without the expense of flowback equipment. These treatments resulted in an 88% economic success rate and only 2 short term oil and grease noncompliance instances in the facilitie overboard water discharge.
