The Arabic language is the most luxurious language in which the Holy Qur’an was revealed, and the words of God and its meanings can only be understood by understanding the secrets of the Arabic language, its rules and terminology, and when extracting some poetic verses that contradict the well-known rule. Some of them may express something abnormal, and others express the same thing as being rare, or necessarily poetic, so I wanted to understand what is meant by these terms, and to clarify the meaning of abnormality and the rule of analogy with it, especially since it may occur to the student that abnormality is rejected, or not eloquent.I chose to study the abnormals that a large population suffers from;  When I saw the various Arabic expressions that describe many of these groups as rare, few, or audible, they are memorized and not measured, although they may be mentioned in abundance in speech, and they can be expressed in the Holy Qur’an without other words that are not described as abnormalities.

Published: May 2022

Introduction: Diabetes Mellitus is a chief reason for morbidity and mortality globally. It is also a major comorbidity contributory factor in COVID-19. Patients with diabetes have an increased susceptibility to viral and bacterial infections, including those affecting the respiratory tract.  Numerous scoring systems have been developed to evaluate and stratify the risk of Community-acquired Pneumonia (CAP). CURB 65 scorings are one of the time tested and relatively easy methods. However, comparative CURB 65 SCORE data analysing its correlation between diabetes mellitus (DM) & non – diabetic mellitus (NDM) in hospitalized covid 19  patients is lacking.  Therefore, this study aimed to evaluate and perform a comparative analysis of CURB 65 scores between diabetic & non–diabetic hospitalized COVID 19 confirmed patients. Methods: This cross-sectional single-centre research evaluated hundred and forty COVID 19 positive patients with and without diabetes from April to June 2021. Following the evaluation of the glycemic status of the patient, CURB 65 scores were calculated. Cohorts were grouped as mild, moderate and severe illnesses, based on the CURB 65 score.  Duration of hospitalisation, the requirement of the ventilator, ICU admission and mortality were recorded. Patients were monitored until they were discharged or deceasement.
U-Pb Scheelite Ages of Tungsten and Antimony Mineralization in the Stibnite-Yellow Pine District, Central Idaho
Authors: Wintzer Niki E. , Schmitz Mark D. , Gillerman Virginia S. , Vervoort Jeffrey D.
Published: May 2022

The Stibnite-Yellow Pine district contains the largest antimony resource in the United States, as well as significant gold, and is a historic producer of tungsten. Application of in situ laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) direct dating of scheelite from two Au-Sb-W ore deposits, Yellow Pine and Hangar Flats, yielded an older group of U-Pb ages in the range of 60.0 ± 2.8 to 57.0 ± 1.1 Ma and a younger U-Pb age for scheelite intergrown with stibnite of 47.4 ± 1.1 Ma. These in situ analyses were calibrated by isotope dilution-thermal ionization mass spectrometry (ID-TIMS) U-Pb lower intercept ages of two coarsely crystalline scheelite samples that yielded ages of 57.52 ± 0.22 and 56.62 ± 0.16 Ma. Scheelite of the latter age is of sufficient quality to serve as a primary reference material for LA-ICP-MS scheelite U-Pb geochronology. The group of older U-Pb scheelite ages agrees with 40Ar/39Ar ages of 56.9 ± 1.2 to 56.38 ± 0.54 Ma on adularia from Yellow Pine and Hangar Flats, whereas the younger U-Pb scheelite age is similar to an 40Ar/39Ar age of 46.00 ± 0.40 Ma on adularia from an epithermal gold-silver deposit in the adjacent Thunder Mountain caldera. Our results indicate that the main stage of tungsten mineralization occurred at ca. 57 Ma, whereas the main stage of antimony mineralization occurred at ca. 47 Ma—thereby providing first-time age constraints for antimony and tungsten mineralization in the Stibnite-Yellow Pine district.
Hybrid-triggered H∞ Fault Detection for Distributed Time-delay Systems with Communication Quantization Based on T-S Fuzzy Model
Authors: Zhang Ying
Published: May 2022

In the network environment, the time-triggered mechanism wastes limited bandwidth resources due to the transmission of all sampled data to the network. The event-triggered mechanism may increase system errors due to ignoring factors such as changes in network utilization. In order to reduce the design conservatism, this paper studies the design of a hybrid-triggered H∞ fault detection filter for a class of nonlinear networked control systems described by Takagi-Sugeno (T-S) fuzzy model, and applies quantization techniques in the communication channel. Using the Lyapunov-Krasovskii functional and integral inequality methods, new results on the stability and H∞ performance of fuzzy fault detection systems are presented. In particular, the designed fault detection filter has a specific H∞ noise attenuation level γ. The final simulation results verify the effectiveness of the design.

Published: May 2022

Objective: To describe a 60-year-old male with diffuse generalized lymphadenopathy preceding a diagnosis of rheumatoid arthritis.Case presentation: The patient was admitted on suspicion of lymphoma. Chest positron emission/computed tomography showed enlarged lymph nodes bilaterally, mediastinum in the perihilar, retroperitoneum, and inguinal regions, with normal hematopoiesis of bone marrow. Lymph node biopsy revealed reactive follicular lymphadenopathy. Polyarthritis was present, and a rheumatoid factor test was positive eight months after the initial medical evaluation. A diagnosis of rheumatoid arthritis associated with generalized lymph node involvement was made. The patient was treated with leflunomide and corticosteroids and showed complete recovery without recurrence at 18 months of follow-up.Conclusions: Once histological findings of reactive lymph node hyperplasia are established as primarily related to rheumatic disease activity, clinicians should consider a possible diagnosis of rheumatoid arthritis.

Authors:   «OilGasScientificResearchProject» Institute, SOCAR, Baku, Azerbaijan, Gasanov Kh.I. , Gasimov Sh.H.
Published: May 2022

The interaction of dithiodiethylamine (cystamine) (L1) with platinum compounds in non-aqueous and aqueous media has been studied. It is shown that in aqueous solutions, the L1 disulfide bond is cleaved, followed by platinum coordination of the resulting β-mercaptoethylamine (mercamine, HL). Depending on the reaction conditions, binuclear complexes of the composition [Pt2(LH)2C14] with bridged chlorine or sulfur atoms or [Pt2L2C12] with bridged chlorine atoms are formed. An X-ray diffraction analysis of the [Pt2(LH)2C14] (I) complex was carried out. Crystals I are rhombic, at 20 °C a=17.283(1), b=9.987(1), c=8.0187(9) Å; R=0.030. Molecule I is a binuclear complex in which platinum atoms are united by a pair of bridged thiolate ligands (-SCH2-CH2-NH+3). The metallocycle Pt2S2 is bent along the sulfursulfur line, so that the dihedral angle between the coordination planes of platinum atoms is 138°. The S-S distance equal to 2.909(1) Å is noticeably shorter than the doubled van- der- vaals radius of the sulfur atom (3.60 Å). The implementation of the reaction in benzene makes it possible to obtain a complex (L1H2)[PtX4] (X=C1, Вг) with the preservation of the sulfur-sulfur bond in the ligand. The structure of the complexes is confirmed by IR spectroscopy data.

Amaç: Araştırmanın amacını, beş farklı kıtadan sanat, bilim ve teknoloji müzelerinin web sitelerinin çocuk ziyaretçilere uygunluğunun tasarım özellikleri, dijital uygulamalar, müze ziyaretini düzenlemeye yönelik içerik bilgisi (duyulara yönelik uygulamalar, atölye ve etkinlik bilgisi) ve müze erişilebilirlik bilgisi (müze haritası ve ödünç alma hizmetleri) açısından incelenmesi oluşturmuştur. Yöntem ve Araçlar: Çalışma nitel araştırma olarak tasarlanmıştır. Verilerin toplanmasında doküman inceleme tekniğinden yararlanılmıştır. Araştırmanın çalışma grubunu beş farklı kıtadan 8 sanat müzesi, 10 bilim ve teknoloji müzesi olmak üzere toplam 18 müzenin web siteleri oluşturmuştur. Veri toplama aracı olarak araştırmacılar tarafından hazırlanan “Müze Web Sitesi İnceleme Formu” kullanılmıştır. Çalışma grubunda yer alan müze web siteleri bağımsız dört değerlendirici tarafından form maddeleri doğrultusunda incelenmiştir. Elde edilen bulgular tablolar halinde sunulmuştur. Sonuçlar: Araştırma sonucunda incelenen beş farklı kıtadan sanat, bilim ve teknoloji müzelerinin web sitelerinin çocuklar için öğrenme ve eğlenme amaçlı kullanıma uygun şekilde tasarlandığı; tasarım ve yazılımının çocuklar için uygun, kolay anlaşılabilir ve kullanıcı dostu olduğu görülmüştür. Aynı zamanda web sitesi bilgilendirme sayfalarındaki içeriklerini görsel ve işitsel olarak destekleyen on üç müze olduğu dikkati çekmektedir. Müzelerin çocuk ziyaretçilerinin bireysel farklılıklarına dikkat etmenin yanı sıra özel gereksinimli çocukları dikkate alarak içeriklerini görsel-işitsel olarak da desteklemesi, eğitimde “fırsat eşitliği” sunması, “kapsayıcı” ve “erişilebilir” olması açısından da son derece önemli olduğu düşünülmektedir. İncelenen müze web sitelerinin sanal müze gezisine ve çocuklara uygun kısa videolara yer verdiği, buna karşın web sitelerinde çocukların yaptıkları ürünleri yükleyebilecekleri ve sergileyebilecekleri uygun etkileşimli bir ortam bulunmadığı, ayrıca çocuklara uygun dijital oyunlara yeterince yer verilmediği görülmüştür. Müzelerin web sitelerinde yer alan bilgilendirme sayfalarındaki içeriklerin çocuklara uygun ve bilgi verici olması büyük bir oranda sağlanmışken, web sitelerinin güncelliğinin sağlanmasının önemli olduğu düşünülmektedir. Müzelerin web sitelerinde çocuk ziyaretçiler için uygun bir müze haritasına yer verildiği görülmüştür. Ödünç alma hizmetleri açısından incelendiğinde ise, bebek taşıma çantası (kanguru) ve bebek arabası ödünç alma bilgisinin çoğu müzenin web sitesinde yer almadığı görülmüştür.

Bu çalışmada farklı ülkelerin değerler eğitimine ilişkin uygulamaları genel bir perspektifte ele alınmış ve dünyada öne çıkan değerler eğitimi programlarından bazıları açıklanmaya ve değerlendirilmeye çalışılmıştır. Değerler eğitimi, çocukları hayata hazırlayan ve topluma faydalı bir vatandaş olmasını destekleyen eğitimin önemli bir parçasıdır. Değerler eğitimi ailede başlar, sosyal çevre ve eğitim kurumlarıyla birlikte şekillenerek gelişmeye devam eder. Okul öncesi dönemde değerler eğitimi çocuğun değerleri içselleştirmesi, yaşamına ve davranışlarına yansıtabilmesi için kritik etkiye sahiptir. Değerler eğitimi uygulamaları kültür, toplum, ülke, zaman gibi birçok faktöre göre değişiklik göstermektedir. Hangi değerlerin kabul edildiği ve toplumda hangi değerlere daha çok önem verildiği ülkelerin değerler eğitimi uygulamalarını farklılaştırmaktadır. Bu çalışmanın amacı, dünyamızda farklı kıtalarda yer alan on üç farklı ülkenin genel değerler eğitimine yönelik uygulamaları hakkında kısa bilgi sunmak ve yine dünyamızda öne çıkan değerler eğitimini destekleyen on farklı eğitim programının genel özelliklerini ele alınmaya çalışmaktır. Çalışmamızda ele alınan ülkeler; Avusturalya, Singapur, Hindistan, Kore, Çin, Hollanda, Slovenya, İsveç, Yeni Zelanda, Almanya, İngiltere, Amerika ve Türkiye’dir. İncelenen on farklı değerler eğitimine yönelik programın öne çıkan özellikleri ya da farklılıklarına dikkat çekilmeye çalışılmış ve ülkemizdeki uygulama çeşitliliğine ilişkin örneklere de yer verilmiştir.

Türkiye’de ortaöğretim kurumlarında sınıf geçme ile ilgili esaslar Millî Eğitim Bakanlığı Ortaöğretim Kurumları Yönetmeliği ile düzenlenmektedir. Anadolu Liselerinde öğrenim gören öğrenciler, Ortaöğretim Kurumları Yönetmeliği gereği 50 not ortalamasına ulaşmaları durumunda zayıf ders sayılarına bakılmaksızın bir üst sınıfa geçebilmektedirler. Araştırmada, örnek durumlar oluşturularak olası notlar belirlenmiş ve öğrencilerin nasıl sınıf geçtikleri tespit edilmiştir. Buna göre öğrenciler, lise öğrenimleri boyunca Matematik, Fizik, Kimya, Tarih, Coğrafya gibi derslerden hiç başarılı olmasalar bile mezun olabilmektedirler. Oysaki ortaöğretim kurumlarının amaçları arasında ortak bir genel kültür kazandırmak, teknolojiden faydalanarak nitelikli eğitim vermek, yabancı dil öğretmek vb. sayılmaktadır. Zayıf ders sayısına bakılmaksızın ortalama ile öğrencilerin sınıf geçmesinin sayılan hedefleri yakalamayı güçleştirdiği düşünülmektedir. Söz konusu durumun lise mezunu sayısını artırdığı, ancak mezunların niteliğini aşağıya çektiği düşünüldüğünden bu makalede Anadolu Liselerinde çalışan öğretmenlerin görüşleri de alınarak Anadolu Liselerinde sınıf geçme sistemi üzerinde önerilerde bulunulmuştur.

This research investigated the typical grammatical structures, topics, and address terms for the victims in the news of Tham Luang cave rescue on Twitter published by four broadcasters: Bangkok Post, CNN International, BBC World News, and ABC News. The sample was 454 news tweets posted by the broadcasters between June 25, 2018 and July 15, 2018. The instruments were a syntactic analysis table, a topic analysis table, and an address term analysis table. The results showed that (1) the most typical grammatical structure used in the news by all broadcasters, except BBC World News, was simple sentence, (2) the most frequently-addressed topics in Bangkok Post and BBC World News were settings, while those in CNN International and ABC News were victims, and (3) the most frequently-used address terms for the victims in the news by Bangkok Post and BBC World News were address terms associated with age and gender combination and those associated with occupation, while this frequency order was in reverse in the news by CNN International and ABC News. Certain statistically significant correlations were also witnessed. The findings provided insights into certain similarities and differences in typical grammatical structures, topics, and address terms in the news tweets posted by the four broadcasters, and they also reflected English-language news publication on Twitter in general.

The purpose of this study was to investigate the effect of despotic leadership on work alienation with the mediating of work boredom. This study was a correlation research method based on structural equation modeling. 253 teachers of Konarak (Iran) were studied by stratified random sampling method. To collect information, three questionnaires were used: despotic leadership, work alienation and work boredom. For data analysis the Pearson correlation coefficient and structural equation modeling were used by SPSS and Lisrel software. Based on results the direct effect of despotic leadership on work alienation, despotic leadership on work boredom and direct effect of work boredom on work alienation was positive and significant. The indirect effect of despotic leadership on work alienation was also significant with the mediator role of work boredom. Thus, school principals who use a despotic leadership style lead to the spread of organizational anomie in the school, and this organizational anomie in turn increase the deviant behaviors of teachers.
A Research of Design, Lateral Stability and Simulation for a Chassis Running in Forest
Authors: Zhu Yue , Kan Jiangming , Liu Fenglu
Published: May 2022

Forest roads are short of structured terrain. Individual wheels often cannot contact the ground when conventional chassis is driving, and the mobility is weak. In addition, the lateral rollover usually occurs. In this article, a forestry chassis with a novel articulated structure with three degrees of freedom (FC-3DOF(II)) is proposed. Compared with conventional chassis, the novel articulated structure is designed, which contributes to achieving full-time contact between wheels and ground. The mobility is improved. For the lateral stability, the previous lateral rollover model of chassis is often established by the geometrical position of COG (center of gravity) of the frame. This method is applied with limitations, which is not universal. Therefore, a new accurate lateral rollover model for FC-3DOF(II) is derived, which predicts the lateral stability by analyzing tire contact forces. The new lateral rollover model is more general and recovers the previous model. To verify the theoretical analysis exactly, the virtual prototype of FC-3DOF(II) is established in SolidWorks, and simulations of lateral rollover are carried out in ADAMS. In simulation experiments, the lateral stability is predicted by analyzing tire contact forces when the inclination of terrain is increasing. Two conditions are considered in simulations. The lateral stability of FC-3DOF(II) and FC-3DOF(II) installed rectangular objects. Compared to the simulation and theoretical results, for FC-3DOF(II), the maximum absolute percent difference of the contact force with the theoretical analysis relative to the simulation is only 1.83%. For FC-3DOF(II) installed rectangular objects, the simulation results show that the lateral rollover is caused by the rear up-slope wheel when the inclination of terrain reaches 34°. The theoretical result relative to the simulation is only 2.90%. The maximum absolute percent difference of the contact force with the theoretical analysis relative to the simulation is only 2.50%. Simulation results validate the effectiveness of the proposed lateral rollover model in two conditions.

Today, transportation network optimization has become one of the significant aspects of supply chain planning, and even a slight rise in productivity can significantly reduce costs of distribution of wood in the transportation network. In the forest based industry, given that transportation is the main cost of raw wood supply, using transportation planning, distribution should be done in a way so as to minimize the overall wood displacement. Such planning must meet the needs of all demand centers and the distribution supplier points must be used to their full capacity. Accordingly, the present study strived to find an optimal solution for transportation and distribution of raw wood from the main supplier points to small and large centers of wood and paper industries in Iran. This optimization simultaneously focuses on several products and is at the macroeconomic level of the country wood market. To achieve this goal, linear programming – Transportation Simplex Algorithm was used. The results show a significant fall in transportation costs and a more organized wood distribution network than the current situation. This cost reduction can be attributed to decisions about the optimal distribution of wood types, determining transport routes, and opting for the right type of truck supplier based on load tonnage and distance. This plummet in transportation costs plunges the cost of wood and wood products, which will surge competition in the business and will be of interest to manufacturers, distributors, customers and stakeholders in general.
