The Law for The Perpetrator of The Great Sin According to Kharijite
Authors: Razzak Lalu Abdul
Published: November 2023

هذا البحث يتناول على مسألة مرتكب الكبيرة التى هي من المسائل العظيمة التي نشأ نزاع الفرق الإسلامية فيها منذ عهد مبكر للإسلام، وذلك بعد مقتل سيدنا عثمان بن عفان رضي الله عنه، في عصر الخليفة الرابعة سيدنا علي رضي الله عنه ظهرت وذلك بعد أمر التحكيم فذهبت فرقة الخوارج إلى تكفير مرتكب الكبيرة وقالوا بخلوده في النار فكفروا بعض أصحاب رسول الله صلى الله عليه وسلم. وللوصول إلى النتائج المرجوة سوف يعتمد الباحث في تناول هذا البحث على المنهج التحليلي وهو عرض آراء الخوارج وآراء أهل السنة في حكم مرتكب الكبيرة. ونتائج البحث هي أن الخوارج أول من أحدث فكرة تكفير مرتكب الكبيرة وذلك بعد أمر التحكيم بين سيدنا علي رضي الله عنه وسيدنا معاوية رضي الله عنه، فزعموا أن قبول التحكيم معصية فكفروا من قبل التحكيم من الصحابة والخوارج ليست على فرقة واحدة وإنما تفرقت إلى فرق متعددة مما تؤدي إلى اختلافهم في الآراء، ولكل فرقة منها إمام. وفكرة تكفير مرتكب الكبيرة ليس من الأمور المجمع على الخوارج، بل هم يختلفون في مرتكب الكبيرة سواء في حكم مرتكب الكبيرة أو أثره في الأحكام الأخروية والدنيوية وفكرة تكفير مرتكب الكبيرة عند الخوارج مبنية على أصلهم في الإيمان، حيث ذهبوا إلى أن الإيمان هو التصديق في القلب والإقرار باللسان والعمل بالجوارح، ويرون أنها شيء واحد، حيث إذا ذهب بعضه ذهب كله.

Local Wisdom in Kebangru'an Rites in Pringgabaya East Lombok
Authors: Sosani Yuga Anggana
Published: November 2023

This paper discusses the local wisdom in the Kebangru'an rite, a traditional procession of the people of Pringgabaya District, East Lombok Regency in overcoming trance disorders. The method used is qualitative ethnography where the researcher is involved and interacts directly in in the community whom is the object of research, to find out the historical value, form of presentation, local wisdom and challenges in the entire series of Kebangru'an Rites. Data collection was conducted by means of observation and in-depth interviews. Observations were made by observing various actions that were patterned and reflected the thinking system of the Kebangru'an Rite activists which included speech, expressions, statements, perspectives on life, and their life history. The results show that as a sacred ritual, the Kebangru'an Rite is identical to the ancient belief of animism. The form of the Kebangru'an Rite is dominated by elements of art: dance and musical accompaniment. A possessed person will dance endlessly to the music of Kebangru'an. Ritus Kebangru'an has its own wisdom for the supporting community: (1) as a medium of transcendental communication between the community and ancestral spirits, (2) as an expression of tradition that contains messages about the description of the cycle of life to death. The wisdom values contained in the Kebangru'an Rite are: (1) as a healing therapy for people in trance, (2) as a source of information from ancestral spirits, (3) as a medium of alternative medicine for the community, (4) foster a sense of concern for others, (5) foster an attitude of mutual cooperation, (6) foster an attitude of discipline and order, and (7) improve religious attitudes. Meanwhile, threats to the sustainability of the Kebangru'an Rite arise from three groups: (1) Ultra modernists who consider that traditional ritual offerings to be something old-fashioned, (2) Puritan religious groups who view the Kebangru'an Rite as a form of shirk and contrary to Islamic teachings. (3) Pragmatic attitudes, namely those who think practically, quickly and instantaneously.

Enhancing Shear Velocity Log Prediction in Ahnet Field, Algeria, Through Well Logs and Machine Learning Techniques
Authors: Goucem Riadh
Published: November 2023

Shear velocity logs are crucial in the oil and gas industry for assessing subsurface mechanical properties, including rock stiffness, shear strength, and seismic wave propagation, essential for optimizing hydrocarbon exploration and production strategies. However, obtaining shear velocity logs conventionally is expensive and time-consuming, especially when drilling additional wells solely for this purpose. With the recent boom in machine learning algorithms adoption across various scientific domains, it proved to be an extremely valuable tool for numerous applications in the oil and gas industry. It makes use of the readily available large datasets collected over decades and leverages this data to train powerful, data-driven models, reducing the reliance on empirical relationships that usually have poor generalization. This study follows this approach and presents the use and comparison of machine learning algorithms for predicting shear velocity logs from conventional and readily available logs in the Ahnet field, Algeria. Ultimately, this study aims to enhance reservoir assessment and optimize hydrocarbon recovery processes, potentially reducing exploration costs and improving oil and gas production decision-making in the region.
Index of Rezidential Development: Evaluation of the Possibility of New Residential Construction Depending on the City Plan
Authors: Vařbuchta Petr , Hromádka Vít
Published: November 2023

This article focuses on the issue of urban development of cities and their residential development from the perspective of spatial planning. Spatial planning fundamentally determines, what kind of construction is feasible in cities. However, spatial plans often do not consider spatial limits, which often go against the proposed ways of using of the given sites, or make their use fundamentally difficult, for example by disproportionately increasing of the costs of residential construction, when it is necessary to remediate old burdens in the defined locality. The subject of the presented research was to examine the possibility of establishing an Index of Residential Development (IoRD), which evaluates the possibilities of residential development in the territory of urban agglomerations. The aim of the research, in the form of establishing of an Index of Residential Development (IoRD), was to assess, how it is possible to consider spatial limits associated with residential construction in urban intravilanes in order to identify the objectives of further spatial development planned by cities. Subsequently, the partial aim of the research was also to create a usable tool for support in the decision making of development organizations on the location of their project in a given space. Based on the results of the research, it was deduced that the limits associated with the residential development in intravilanes based on the IoRD could be considered. Clear links were also shown between the limits in the territory and the impaired possibility of construction in cities with zoning plans, which did not respond to the limits in the territory by adding other design zones, or completely ignored them. Although the methodology for determining of the Index of Residential Development (IoRD) was verified due to the availability of data in the case study carried out in the Czech Republic – the city of Brno, the methodology is applicable to any urban agglomeration even outside the Czech Republic when fulfilling the conditions defined in the article.

(1) Background: Urinary tract infections (UTIs) are an important cause of perinatal and maternal morbidity and mortality. The aim of this study was to describe and compare the main pregnancy outcomes among pregnant patients with complicated and uncomplicated UTIs; (2) Methods: This retrospective study included 183 pregnant patients who were evaluated for uncomplicated UTIs and urosepsis in the Urology Department of ‘C.I. Parhon’ University Hospital, and who were followed up at a tertiary maternity hospital- ‘Cuza-voda’ from Romania between January 2014 and October 2023. The control group (183 patients) was randomly selected from the patient’s cohort who gave birth in the same time frame at the maternity hospital without urinary pathology. Clinical and paraclinical data was examined. Descriptive statistics and a conditional logistic regression model were used to analyze our data. (3) Results: Our results indicated that patients with urosepsis had increased risk of premature rupture of membranes (aOR: 5.59, 95%CI: 2.02- 15.40, p< 0.001) and preterm birth (aOR: 2.47, 95%CI: 1.15- 5.33, p= 0.02). We could not demonstrate a statistically significant association between intrauterine growth restriction and preeclampsia with the studied urological pathologies. (4) Conclusions: Careful UTIs screening during pregnancy is needed for preventing maternal-fetal complications.
Efficiency and Vulnerability in Networks. A Game Theoretical Approach
Authors: Manuel Conrado M. , Ortega Eduardo
Published: November 2023

Defining measures of network efficiency and vulnerability for networks is a pivotal aspect in modern networking paradigms. We approach this problem from a game-theoretical perspective. We will consider networks in which actors have social or economic interests modeled by means of a cooperative game. This allows to define, for each network, a family of efficiency measures and another of vulnerability measures, parameterized by the game. The proposed measures use the within groups and the between groups Myerson values. These two values respectively measure which part of the classical allocation of Myerson corresponds to the productivity of players and which part to the intermediation costs. Also, which part of total centrality in social networks is due to communication or to beteewnness. In our proposal, the efficiency of a network is the proportion of the total productivity (or centrality) that players can retain using the network topology. The intermediation costs (and the betweenness centrality) can be viewed as a weakness with a negative impact. Then, we propose to calculate vulnerability as the proportion expent by players in intermediation payments. We explore the properties of these measures and we particularize them to several structures and particular games, also analyzing their asymptotic behaviour.

Published: November 2023

Ultra high molecular weight polyethylene (UHMWPE) is a thermoplastic high-performance polymer in high demand for biomedicine, ship and machine building, anthropomorphic robots and smart prostheses. Highly oriented UHMWPE fibers possess record specific strength and may also be used for the fabrication of self-reinforced PE-PE composites (SRPEC). The temperature evolution study of the small-angle X-ray scattering (SAXS) signature of the supramolecular structure of UHMWPE can help reveal their important role in the mechanism of the shape memory effect in SRPEC. The laboratory SAXS–WAXS beamline XEUSS 3.0 was used for in situ studies of the nanostructure parameters in unidirectional SRPEC. Namely, the radius of gyration and the dimensionality factor were extracted from 2D SAXS patterns using several fitting algorithms. Significant changes of these parameters occurred in temperature ranges that correspond to the initiation of the shape memory effect and melting. The relationship between the material anisotropy and 2D SAXS patterns are discussed in the context of the supramolecular structure evolution.

Organic light-emitting diodes (OLEDs) have ushered in a technological revolution with their remarkable impact on diverse sectors of our daily lives. These versatile devices known for their outstanding display and lighting capabilities, have become indispensable components in various industries including smartphones, tablets, televisions, and automotive applications. This paper delves into the development of a group of twisted donor-acceptor-donor (D-A-D) derivatives incorporating bicarbazole and benzophenone structures for potential use as blue emitters in OLEDs. The synthesized compounds, namely DB14, DB23 and DB29, were designed with various alkyl side chains to enhance their film forming properties as for blue emitters. Characterization and evaluation of these derivatives included photophysical, electrochemical, thermal, and electroluminescent analysis. Some of the OLED devices incorporating these emitters demonstrated promising performance with maximum current efficiency (CEmax) of 2.6 cd/A and external quantum efficiency (EQEmax) of 5.3%. Notably, the DB23 emitter exhibited the highest EQE among all devices. The study also emphasizes the influence of host-guest energy transfer, optimal doping concentrations, and molecular structures on device performance. This research not only contributes to the understanding of advanced OLED materials but also provides insights into designing efficient blue emitters for future display and lighting applications, thereby advancing the field of organic electronics.

Authors: Guo Xiao-Lin , Sun Bohua
Published: November 2023

Snap-fit is a commonly used jointing/connention mechanism, and its easy installation and difficult removal are the result of the coordinated interaction between friction, geometric shape, and elasticity. This paper presents a detailed study on the assembly/disassembly forces of thin-walled torus snap-fit through finite element simulation, experimental testing, and data fitting of approximate analytical solutions. The research reveals that the non-zero Gaussian curvature of the torus has a significant impact on the mechanical performance of the torus snap fit. The findings in this study are of great significance for future design of high-performance structural connections.

Published: November 2023

This study presents virtual reality (VR) videos as an effective technique for delivering extension educational materials on manure and mortality management. Virtual reality is a technology that can enable immersive distance learning. Using VR tours can enable the public to learn manure and mortality management technologies without in-person farm visits, thus saving traveling time and money and avoiding exposure to pathogens and noxious odors in farms. As the first part of this project, 360° VR tours were created on multiple aspects of manure management, including composting, anaerobic digestion, and preliminary wastewater treatment. These videos were presented to a diverse audience of agricultural producers, extension specialists, and researchers through in-person and online extension events and the Texas Manure YouTube channel. The effectiveness of videos was evaluated using surveys, which measured the audience's awareness of the topics before and after watching VR videos. Statistical analysis revealed that the increase in awareness after watching the videos was statistically significant, with a p-value of less than 0.0001. Statistical analysis also revealed that job classification and professional experience significantly impacted the change in awareness. Researchers, extension specialists/agents, and participants with less experience in manure and mortality management experienced a greater change in awareness than agricultural producers and participants with more experience. Interest and impression of the audience on the VR videos was also evaluated. According to survey data, the majority of the audience rated these videos as an effective technique for educating the public about manure and mortality management, found the VR videos interesting, were willing to learn more content through VR videos, and were likely to recommend them to their colleagues. A statistically significant correlation could be observed between the awareness change and the effectiveness rating given to the videos by the participant.
A Common Polymorphism in RNASE6 Impacts Its Antimicrobial Activity Toward Uropathogenic Escherichia coli
Authors: Anguita Raul , Prats-Ejarque Guillem , Moussaoui Mohammed , Becknell Brian , Boix Ester
Published: November 2023

Human Ribonuclease (RNase) 6 is a monocyte and macrophage-derived protein with potent an-timicrobial activity toward uropathogenic bacteria. The RNASE6 gene is heterogeneous in hu-mans due to the presence of single nucleotide polymorphisms (SNPs). RNASE6 rs1045922 is the most common non-synonymous SNP, resulting in a G to A substitution that determines an ar-ginine (R) to glutamine (Q) transversion at position 66 in the protein sequence. By structural analysis we observed that R66Q substitution significantly reduces the positive electrostatic charge at the protein surface. Here, we generated both recombinant RNase 6 -R66 and -Q66 protein variants and determined their antimicrobial activity toward uropathogenic Escherichia coli (UPEC), the most common cause of UTI. We found that the R66 variant, encoded by the major SNP rs1045922 allele, exhibited superior bactericidal activity in comparison to the Q66 variant. The higher bactericidal activity of R66 variant correlated with an increase in the protein lipopolysac-charide binding and bacterial agglutination abilities, while retaining the same enzymatic effi-ciency. These findings encourage further work to evaluate RNASE6 SNP distribution and its impact in UTI susceptibility.

The processes of hydrogen reduction of silicon and germanium chlorides under the conditions of high-frequency (40.68 MHz) counteracted arc discharge stabilized between two rod electrodes are investigated. The main gas-phase and solid products of plasma-chemical transformations are determined. Thermodynamic analysis of SiCl4 + H2 and GeCl4 + H2 systems for optimal process parameters was carried out. Using the example of hydrogen reduction of SiCl4 by the method of numerical modeling, gas-dynamic and thermal processes for this type of discharge are investigated. The impurity composition of gas-phase and solid reaction products is investigated. The possibility of single-stage production of high-purity Si and Ge mainly in the form of compact ingots, as well as high-purity chlorosilanes and trichlorogermane, is shown.

Myofascial Pain Syndrome (MPS) is a prevalent chronic pain disorder characterized by myofascial trigger points (MTrPs). Current diagnosis relies on manual detection of MTrPs, which has low inter-rater reliability. This study aims to enhance diagnosis through machine learning (ML) and a combination of texture-features extracted from B-mode ultrasound (B-mode-US) images. Four texture-features were investigated: statistical-features, and their combination with Gabor, local binary (LBP), and SEGL, LBP + gray-level-co-occurrence-matrices + Edge for the classification of MTrPs on the B-mode-US images. B-mode-US images of trapezius muscles (n=90) were examined for MTrPs and healthy muscle. Three methods of LBP, SEGL, and Gabor were separately calculated for each B-mode-US image. Then, the statistical-features (e.g., entropy) were calculated over the B-mode-US images and those three methods. Seven Machine learning (ML) classifiers (e.g., neural network) with the calculated statistical-features were applied to discriminate MTrPs from healthy muscle. Additionally, traditional statistical analysis (i.e., ANOVA) was calculated between statistical-features within each method. The results indicated that the combination of statistical-features effectively discriminated between MTrPs and healthy muscles, based on traditional statistical analysis. However, ML classifiers struggled due to high variation and similar mean values among them. This discrepancy between them prompts further exploration of US texture-based automated ML for MTrPs diagnosis.

Background: Infective endocarditis(IE) is a serious disease and in many cases surgery is necessary. Whether the type of prosthesis implanted for aortic valve replacement(AVR) for IE impacts patient survival is a matter of debate. The aim of the present study is to quantify differences in long-term survival, recurrence of endocarditis AVR for IE according to prosthesis type among patients aged 40 to 65 years. Methods: This was an analysis of the INFECT-REGISTRY. Overall, 4365 patients were diagnosed and operated on for IE from 2000 to 2021. Of these, 549 aged between 40 and 65 years underwent AVR. 268(48.8%) received mechanical prostheses, and 281(51.2%) biological ones. Confounders were adjusted using optimal full matching propensity score. Results: A significant trend in reduction of implantation of mechanical vs biological prostheses was observed during the study period(p<0.0001). Long-term survival was significantly higher among patients receiving a mechanical prosthesis than those receiving a biological prosthesis (hazard ratio [HR] 0.546,95%CI: 0.322-0.926, p=0.025). Mechanical prostheses were significantly associated with less recurrent endocarditis after AVR (HR 0.268,95%CI:0.077-0.933,p=0.039).Conclusions: The present analysis of the INFECT-REGISTRY shows increased survival and reduced recurrence of endocarditis after mechanical aortic valve prosthesis implant for IE in middle-aged patients.

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma and a heterogeneous disease characterized by mature B-cell neoplasms. The standard immunochemotherapy for DLBCL is R-CHOP, which includes rituximab, cyclophosphamide, doxoru-bicin, vincristine, and prednisone. Up to 30-40% of patients with DLBCL either exhibit primary refractory disease to standard treatment or experience relapse after the initial response. A 72-year-old man diagnosed with DLBCL involving chromosomal translocations t(1;22)(q21;q11.2) and t(6;18)(p25;q21) showed primary refractory disease after the fourth cycle of R-CHOP. The patient ultimately experienced cardiac involvement by the lymphoma and received salvage chemotherapy. He passed away about 15 months away after the diagnosis of DLBCL. We conducted fluorescence in situ hybridization (FISH) for further analysis of the chromosomal translocations. The breakpoint of chromosome 1q21 was located at a distance of around 151 Mb from the telomeric end of chromosome 1p. The breakpoint in chromosome 22q11 contains the immunoglobulin lambda locus. Furthermore, the breakpoint of chromosome 6p was in the telomeric region of chromosome 6p21. The breakpoint of chromosome 18q21 contains BCL2. This case report presents the first documented co-occurrence of chromosomal translocations t(1;22)(q21;q11.2) and t(6;18)(p25;q21) in a patient with DLBCL. These chromosomal translocations may indicate a worse clinical outcome.
Hyperbolic volume of 3-d manifolds, A-polynomials, numerical hypothesis testing

We continue our study of the connections between the hyperbolic volume of the complement of a knot in the three dimensional sphere with topological invariants of this knot. This time we pay attention to A(M,L) parametrization for the affine variety with casp, produced by a knot (so-called A-polynomials). Then, using the known expressions of A-polynomials for number of knots we present results of the numerical tests for the conjectures on asymptotics of solutions of q-difference equations connected with the hyperbolic volume of these knots.

Mussels survive a few days after harvesting, limiting the trade of these animals when alive. The study evaluated the effect of nylon net packing on the survival and shelf life of Perna perna mussels farmed in Brazil. Thirty samples containing 10 or 11 market-size mussels were stored in an incubator at 4°C for four days, half packed with nylon netting and the other half maintained within opened containers. The experiment analyzed the following parameters daily: survivorship, intervalvar fluid loss, total volatile bases, pH, and mesophilic and psychrotrophic bacteria counts. By the end of the assay, chemical and microbiological parameters were all acceptable for human consumption. All packed mussels survived up to the second day of storage, while the control group recorded an average survival of 29.7% in the same period. Packed mussels survive longer, probably because the tight net prevents animals from losing liquid by maintaining their shell valves closed during storage. This packaging method extends the shelf life of live products and improves the potential trading live mussels to consumer centers far from marine farms.
SOFTWARE FOR INTERPRETING THE RESULTS OF VERTICAL ELECTRICAL SOUNDING IN THE FORM OF A THREE-LAYER GEOELECTRIC STRUCTURE
Authors: Rudenko Serhii , Koliushko Denis
Published: November 2023

By monitoring the state of the grounding system, electrical engineering personnel must independently solve the problem of interpreting the results of vertical electrical sounding (VES) of the soil using their own knowledge and practical experience. During the interpretation, outdated palettes or expensive software complexes are used, which allow analyzing only two-layer soils. This leads to a large number of errors and inaccuracies in the assessment of the state of the grounding system and worsens their operation. In this regard, a program was developed for the interpretation of the results of the VES in the form of a three-layer geoelectrical structure. The program is implemented in the Delphi programming language and contains two parts: computational and graphic. The computational part of the program uses point source current, Hooke-Jives, equivalence and reliability theory methods to optimize the determination of geoelectric model parameters. The graphical part allows the user to visualize the obtained results and perform their analysis. To confirm the reliability of the developed program, a comparison of the results of the experimental measurement of the resistance of the grounding arrangmants with the results of the calculation using the program was made for 65 substations with a voltage class of 35 kV of one of the regional energy companies of Ukraine. The obtained results showed that the program gives reliable results and can improve the quality of monitoring the condition of grounding systems, and accordingly increase the reliability and safety of operation of electrical stations and substations.
