Authors: Abraham Onwuezobe Ifeanyi , Akeruke Unwana Ezekiel , Agantem Ekuma Emmanuel
Published: December 2023

Background: Carbapen­emase enzymes such as metallo-β-lactamase (MβL) belong to Amber class B type of β- lactamase that cause serious clinical infections mostly feared due to the associated antibiotic resistance mechanisms resulting from their ability to hydrolyse virtually all β-lactam agents, including the carbapenems. Aim: To investigate the occurrence as well as determine the associated risk factors of metallo- β -lactamase producing bacterial agents of infection among in Uyo, Southern Nigeria. Methods: A clean-catch, mid-stream urine and wound samples were collected from consented patients and cultured according to standard procedure. The isolated pathogens were subjected to antibiotic susceptibility testing using the Kirby Bauer method. All Imipenem and Ertapenem resistant isolates were used for of MβL detection, using Total Metallo-β-Lactamase confirmation Kit. Results: Of the 157 Gram-negative bacteria isolates from 312 clinical samples of urine and wound, metallobeta-lactamase (MβL) was detected in 12 (7.6%). The highest MβL producing Gram-negative bacteria isolate from urine was Escherichia coli. However, Pseudomonas aeruginosa was the major producer from wound the samples. Overall, the antibiotic sensitivity profile revealed that the isolates were mostly sensitive to imipenem 123(91.0%) and highly resistant to the commonly used antibiotics in the study area. The associated risk factors of note were the participants residence, antibiotic use and duration of wound infection and they were found to be statistically significant (P = <0.05). Conclusion: The prevalence of metallo-ß-lactamase producing bacterial agents in Uyo, Nigeria was found to be 7.6%. In addition, while E. coli and P. aeruginosa were the major MβL producers, the participant’s place of residence, antibiotics use and wound duration were found to be associated with their occurrence.
Politicization, Ratification of International Agreements, and Domestic Political Competition in Non-Democracies: The Case of Iran and the Paris Climate Accords
Authors: BAYER Reşat , TAFAZZOLI Bıjan
Published: December 2023

While some degree of competition is present in many authoritarian regimes, the implications of such controlled competition on international issues have not received much consideration, including towards international environmental accords. We attempt to rectify this through a framework where we focus on internal political competition in a hybrid, nondemocratic system where national elections are held regularly. Specifically, we argue that the presence of multiple actors competing in elections in nondemocratic settings results in them assuming positions on various issues, justifying their positions, and attempting to mobilize their supporters with considerable implications for international environmental policies. We display our argument in the context of Iranian debates on the ratification of the Paris Climate Accords. Our findings demonstrate that the competing Iranian sides rely on different justifications for their environmental positions, resulting in extensive (negative) competitions of rhetoric where the international dimension emerges as an important feature in the internal competition. Overall, we show that political competition within non-democracies is likely to add to the complexity of international (environmental) negotiations and cooperation.

Published: December 2023

This paper delves into an assessment of the impact of Turkey’s quest for status since the 2000s on changes in its foreign policy. In other words, how has Turkey’s search for status influenced its foreign policy stances since the 2000s? And can we consider the changes in Turkey’s foreign policy change transformational or transactional in essence? In this vein, this paper will make essential contributions to the existing literature on Turkey’s status-seeking strategies by using specific cases to link them to changes in Turkey’s foreign policy and assessing the extent to which they are transactional or transformational. The examination of this topic is all the more important in light of internal developments in Turkey, such as democratic backsliding and economic crisis, as well external

factors such as its tense relationships with the EU, its rapprochement with Russia and China, and its increasingly proactive profile in regional crises. This paper critically assesses the pattern of Turkey’s foreign policy change from transformational and transactional perspectives.

Published: December 2023

Bireylerin serbest zaman aktivitelerini etkili bir şekilde düzenlememesinin veya anormal boş zaman davranışları sergilemesinin, onların boş zaman okuryazarlığı eksikliğiyle bir ilgisi olup olmadığı konusu tartışmalıdır. Fakat serbest zaman okuryazarlığı ile açık alan rekreasyon faaliyetlerine katılımın arasındaki ilişkinin karmaşıklığı da gizemini korumaktadır. Bu noktadan hareketle oluşturulan bu betimsel tarama araştırmasının amacı; açık alan rekreasyon katılımcıların, serbest zaman okuryazarlık sürecinin cinsiyet, algılanan gelir ve rekreasyonel faaliyetlere katılım şekli değişkenleri açısından farklılaşıp farklılaşmadığının tespit edilmesidir. Araştırmada, betimsel tarama deseni ile birlikte basit tesadüfi örnekleme yöntemi tercih edilmiştir. Araştırmada yazarlar tarafından oluşturulmuş cinsiyet, algılanan gelir durumu ve rekreasyonel faaliyetlere katılım şekli bilgilerinin yer aldığı demografik bilgi formunun yanı sıra katılımcıların serbest zaman okuryazarlık düzeyini belirlemek amacıyla Serbest Zaman Okuryazarlığı Ölçeği (SZOÖ) kullanılmıştır. Araştırmada toplam 332 form teslim alınırken 17 adet form eksik ve yanlış doldurulduğu için kapsam dışı bırakılmıştır ve böylelikle araştırmada 142 kadın 173 erkek olmak üzere toplam 315 kişiye ulaşılmıştır. Verilerin analizi ise Jamovi paket programı ile gerçekleştirilmiştir. Elde edilen bulgulara göre; serbest zaman okuryazarlığının bazı alt boyutları ile gelir arasında anlamlı farklılık bulunmakta iken cinsiyet değişkeni ile serbest zaman okuryazarlığı arasında farklılık tespit edilmemiştir. Sonuç olarak; serbest zaman okuryazarlığı noktasında bireyin rekreasyonel faaliyetlere katılım şekli ve gelir durumu etkili bir unsur olarak değerlendirilebilir.
Şâmî’nin Sübülü’l-Hüdâ Adlı Eserinde Anlatım Üslupları ve Arap Dili Kaynakları
Authors: SEZER Mustafa
Published: December 2023

Memlükler dönemi (1250-1517) Mısır, özellikle Moğol istilası sonrasında âlimlerin göç ettiği, büyük ilim adamlarının yetiştiği münbit bir coğrafya haline gelmiştir. Bu vaziyet, Osmanlıların (1299-1922) bölgeyi fetihleri sonrasındaki valiler döneminde de bir müddet devam etmiştir. İlgili süreç içerisinde âlimler, hacimli külliyât eser-ler telif etmişler, erken dönemlerden kendi dönemlerine kadar rivâyet-dirâyet üs-lubunca ilim geleneğini sürdürerek sonraki nesillere aktarmışlardır. Bu hacimli an-siklopedik teliflerden birisi de Muhammed b. Yûsuf es-Sâlihî eş-Şâmî’nin (ö. 942/1536) ömrünün son zamanlarında tamamladığı Sübülü’l-hüdâ ve’r-reşâd fî sîreti hayri’l-ibâd adlı Hz. Muhammed (s) konulu devasa eserdir. Eser, Hz. Peygamber’i tüm yönleriyle ele aldığı için delâil, siyer-meğâzî, şemâil, hasâis, mu‘cizât, fezâil ve biyografiler, tıbb-ı Nebevî gibi alanlarda rivayetler ve zengin bilgiler içermektedir. Aynı zamanda müellif Şâmî, kendi dönemine kadar telif edilmiş geniş bir edebiyat-tan yararlanarak onlara atıflarda bulunmuştur. Bu kadar şümullü bir kaynaktan ya-rarlanması, eserde Arap diline ait önemli nazım ve nesir metinleri ihtiva etmesini sonuçlandırmış böylece değişik temalarda mebzul miktarda Arap şiiri eserde yer almıştır. Ayrıca eser rivayet-dirayet üslubuyla mevcut muhtelif metinleri içerme-sinden ötürü üslûp bakımından câlibi dikkattir. Bu bağlamda rivayetçilik, tasvirîlik, tematik şiir anlatımları, ilmîlik, öğreticilik, açıklayıcılık, kantlayıcılık ve destansı-lık müellifin benimsediği belli anlatım üsluplarıdır. Ayrıca eserde eyyâmü’l-Arab ve siyer-meğâzî anlatımlarına bolca yer verilmesi siyer-tarih metinlerinin Arap diliyle münasebetinin irdelenmesini gerektirmiştir. Eserde gramer analizlerinin yapılması ve her konu sonunda müfredât ve sözlük kısımlarının oluşturulması onu orijinal kı-lan hususiyetlerdendir. Böylece modern dönemde dil vb. eğitim setlerinde ve de muhtelif bilimsel eserlerde müfredat bölümleri oluşturan eserlere öncülük yapmış-tır. Müellif Şâmî’nin kaleme aldığı Sübülü’l-hüdâ adlı eser, içerdiği edebî metinler ve Arap diline dair müfredâtlar, tahlil ve analizler bakımından kıymet ifade eden ve araştırılması gereken bir eserdir. Ayrıca müellifinin Arap diline dair müellefâtının olması, eserinde onlara atıflarda bulunması da müellifin siyer ve tarih âlimi olma-sının yanında önemli bir Arap dilcisi olduğunun ispatı mahiyetindedir.
Arap Şiirindeki Bazı Rivayet Farklılıklarının Nahiv Kurallarına Etkisi
Authors: İNANÇ Yunus
Published: December 2023

Nahiv kaideleri, dilleri bozulmamış Arapların sözlerinden çeşitli yöntem ve veriler kullanılarak çıkarılmış kurallar bütünüdür. Dilcilerin kural çıkarmada kullandıkları yöntemlerin başında icmâ, kıyâs ve istishâb gelmektedir. Dilciler derledikleri malzemeleri bu yöntemlerle işleyerek nahiv kurallarını vaz etmişlerdir. Derlenen malzemelerin temelini ise nakle dayalı veriler oluşturmuştur. Nakil veya bir diğer ifadeyle rivayet yoluyla elde edilen dil malzemelerini kendi dil selikalarını da işe katarak yorumlamışlar ve kurallarını vaz etmişlerdir. Bu çerçevedeki nakil verilerinin başında sahih kıraat vecihleriyle birlikte Kur’ân, dildeki delilliği tartışmalı olsa da hadîs-i şerîfler, şiir ve nesri içine alan Arap sözleri yer almıştır. Bu çalışmada rivayete dayalı dil kaynaklarından olan şiirin nahiv kuralları üzerindeki etkisini gösteren ve kısmen detay sayılabilecek bir yönüne temas edilecektir. Zira bazı nahiv eserlerinde bazı şiirlerle ilgili farklı rivayetlere yer verilmiştir. Delil olarak zikredilen şiirlerdeki bazı kelimelerin başka bir rivayette farklı şekilde yer aldığından söz edilmiştir. Bu tür rivayet farklılıklarından kimisinin ilgili nahiv kuralına etkisi olmazken kimi rivayet farklılıkları nahiv kuralının yönünü değiştirmiştir. Nahivcilerin geneli tarafından zikredilen delile göre mümkün görülmeyen bir kullanımın şahit olarak getirilen deliller içindeki şiirin farklı bir rivayetine göre mümkün görülebildiği tespit edilmiştir. Bir delile göre tek ihtimal söz konusu iken ilgili delilin farklı bir rivayetine göre ikinci bir ihtimale daha kapı aralandığı, bir diğer ifadeyle farklı rivayetlerle nakledilen şiirlerin bazı nahiv kurallarında dikkate alınabilecek düzeyde etkisinin olduğu tespit edilmiştir. Bu çalışmada tespit edilen söz konusu rivayet farklılıklarının nahiv kurallarına etkisi ele alınacaktır. Giriş bölümünde nahivcilerin kullandıkları yöntem ve delillerden bahsedilecek, daha sonra farklı şiir rivayetlerinin bazı nahiv kuralları üzerindeki etkisi çeşitli başlıklar altında örnekler üzerinden ele alınacaktır.
Kaybedilen Rumeli Toprakları Hakkında Meşîhate İntikal Eden Meseleler
Authors: ARSLAN Emine
Published: December 2023

Meşîhat kurumu yüzyıllar boyunca müslümanların fetvâ mahiyetindeki sorularına muhatap olmuştur. Bu sorular devletin hakimiyeti altındaki bölgelerden olduğu gibi Osmanlı padişahının müslümanların halifesi olması hasebiyle hakimiyet haricindeki bölgelerden de gelmiştir. Osmanlı’nın zaman içerisinde çekilmek zorunda kaldığı yerlerde geride kalan müslüman nüfus da karşılaştıkları dînî, bazen de hukûkî meselelerinin çözümünü hala bu konularda bağlı oldukları Meşîhate başvurmakta bulmuşlardır. Bazı yerlerde bu geri çekiliş daimî olmuş bazı yerlerde ise tekrar hakimiyetin tesis edildiği dönemler olmuştur. Düşman istîlâsına uğradıktan sonra tekrar ele geçirilmiş Rumeli topraklarına Mora güzel bir örnektir. Her ne kadar daha sonra tekrar ve katʻî olarak kaybedilse de aradaki dönemde arazi ve emlâkın istîlâdan önceki sahiplerine iâdesi vb. meseleler Meşîhate yöneltilen fetvâ taleplerine konu olmuştur. Dâimî olarak hakimiyetten çıkan Bulgaristan, Yunanistan, Karadağ gibi ülkelerde ise azınlık haline gelen müslümanlar -yapılan anlaşmalar gereği- dînî ve kazâî işleri konusunda halife olarak Osmanlı padişahına, dolayısıyla Meşîhâte bağlı kalmaya devam etmişlerdir. Elbette bu süreç pürüzsüz bir şekilde işlememiş müftülerin tayinleri, görev ve yetkileri konusunda sık sık problemler yaşanmıştır. Rumeli topraklarından, vakıf toprak ve emlâkinin nasıl tasarruf edileceği, İslam Bankası kurulmasının câiz olup olmadığı, evvelden öşür arazisi olan yerlerin durumunun ne olduğu, vatandaşı oldukları devlet ile Osmanlı’nın yapmış olduğu anlaşma mûcebince müftülerin seçiminin nasıl olacağı, müslüman bir kadının vefatından sonra tabip tarafından muayenesinin câiz olup olmadığı vb. hususlar hakkında Meşîhate sorular sorulmuştur. Bütün bunlar göstermektedir ki uzun bir süre yönetilmiş Rumeli topraklarından askerî ve siyâsî olarak çekilmiş olmak bir anda bütün bağların kopmasını sağlamamış, Meşîhat kurumu geride kalan müslüman halkın dinî konularda ve toplumsal hayatta karşılaştıkları sorunların çözümünde Osmanlı’nın tarih sahnesinden çekildiği son ana kadar muhatap olmaya devam etmiştir.

Published: December 2023

Plant leaf blight is a common disease that affects many crops, causing significant economic losses in agriculture. Early detection of blight is essential for farmers to prevent the spread of the disease, control its severity, and improve crop yields. Manual detection of blight is time-consuming and often unreliable, making it necessary to use advanced technologies for accurate and efficient detection. Plant leaf blight detection systems can help farmers monitor their crops in real-time and identify blight at an early stage. This enables farmers to take appropriate measures such as crop rotation, timely application of fungicides, and improving plant nutrition to prevent the spread of the disease. By using plant leaf blight detection systems, farmers can reduce the economic losses caused by the disease and ensure the availability of healthy crops for consumption. This project presents a smart system for leaf blight detection that uses deep learning and convolutional neural networks (CNN) and is implemented on an Android platform. The system comprises an image acquisition module, a pre-processing module, and a leaf blight classification module. The image acquisition module captures images of leaves from a mobile camera, while the pre-processing module enhances the quality of images by removing noise and enhancing contrast. The leaf blight classification module uses a pre-trained CNN model to accurately classify images into healthy or diseased categories and provide the Confidence level of the Blight (disease) present.

Published: December 2023

—This research project investigates whether there is a significant difference in the average age of death between left-handers and right-handers by analyzing age distribution data collected from a National Geographic survey. Utilizing Bayesian statistics and data visualization techniques, the study calculates the probability of being a specific age at death based on handedness. The results reveal that there is insufficient evidence to support the claim that left-handers experience an earlier average age of death, challenging a commonly held belief. This evidence-based analysis contributes valuable insights to the discussion on handedness and longevity, highlighting the importance of rigorous data-driven research in dispelling prevailing myths.
CHOLAMANDAL ARTISTS’ VILLAGE: AN INTERACTION BETWEEN THE TRADITION AND MODERNITY (INDIA, THE MADRAS SCHOOL)
Authors:   Kharkiv State Academy of Design and Arts, HORBACHOVA Valeriia
Published: December 2023

Based on the analysis of scientific literature, a successful example of an independent and self-organized community of Cholamandal artists was studied as a continuation of the artistic searches and experiments of the Madras school during the second half of the 20th – early 21st centuries. The prerequisites for the emergence and development of the Cholamandal commune headed by K. Paniker are analyzed. The activities of individual artists of the art association – painters (K. Paniker, R. Pooviah, T. Tarani), graphic artists (K. Haridasan, K. Ramanujam), sculptors (C. Patnaik, S. Nandagopal) and others are considered. The plot and thematic features of their achievements are clarified – the search for original interaction with folk, religious and tantric art is characteristic for these artists. The special position of folk art becomes one of the distinguishing features of the association’s activities. Traditions and their inheritance are seen as an important communicative part and as a source of experiments for modern practices, which, in turn, supported the cross-platform nature of Cholamandal. The settlement included not only workshops and an exhibition gallery, but also an open-air theater for dancing and theatrical performances, a textile workshop, a library and all the necessary infrastructure for everyday life. Cholamandal artists are known for their experiments with traditional Indian techniques and materials such as terracotta, bronze casting, a combination of fresco and oil painting. They combined these techniques with contemporary styles and themes to create unique works of art, reflecting the richness and complexity of India’s artistic tradition. The Cholamandal commune also played an important role in popularizing of modern Indian art among a wide audience. Art exhibitions and events held at Cholamandal attracted art enthusiasts and collectors from all over India and abroad and have helped bring Indian contemporary art to the attention of the global art scene.

Published: December 2023

In electric shocks, lung tissue is a poor conductor and has low resistance. Therefore, they are not very sensitive to the development of tissue damage due to electric current. In this study, we wanted to present a rare case of lung parenchymal burn as a result of electric shock. A 21-year-old male patient was brought to the emergency department by ambulance after being electrocuted with a current of 15,000 volts after contact with a high voltage line while working with a construction machine. The general condition of the patient was good and vital signs were stable. However, his pulse oxygen value was 74 and his breathing was slightly tachypneic. There were no lesions in the chest and abdomen due to electrical burns. Radiologic imaging showed bilateral diffuse tissue damage in the lung tissue. The patient was referred to a tertiary care institution with an intensive care burn unit. In traumas caused by high-voltage electric shock, burns on the body surface may be insufficient to determine the severity of the trauma. A multidisciplinary approach must be provided to these patients.

Changes in the anatomical and functional parameters of the eye when using glasses with Stellest™ lenses in children with progressive myopia
Authors: Cherednichenko N. L. , Korenyak G. V. , Gappoeva A. Sh.
Published: December 2023

Relevance. Myopia is one of the most common refractive pathologies in the world. By 2050, according to WHO 2015, more than half of the world’s population will suffer from myopia, which will lead to the risk of developing pathologies associated with the progression of myopia, such as glaucoma, macular degeneration and retinal detachment. The use of various modern methods to control myopia can slow down the progression of myopia, which potentially reduces the risks of complications. Objective: to evaluate changes in the anatomical and functional parameters of the eye (clinical refraction, axial length, accommodation functions) in children with progressive myopia corrected with glasses with Stellest lenses in different age groups. Materials and methods. The study was conducted on the basis of the Eye Microsurgery Clinic of the Stavrapol State Medical University. Glasses with Stellest lenses were assigned to 80 children aged 8 to 16 years. The average age of the children was 11 ± 0.12 years. The children were divided into three age groups: 1st – primary school; 2nd -middle school; Group 3 – senior school. After the examination, the children were selected glasses with Stellest lenses. The average period of wearing glasses with Stellest lenses was 12 months. Clinical refraction, axial length and accommodation functions were evaluated during the observation. Results. The change in refraction depended on the age of the child. The greatest increase in refraction by 0.40 ± 0.02 D was observed in the younger age group, and the smallest (0.27 ± 0.02 D) in children of secondary school age. In the group of children of senior school age, the increase in refraction was +0.32 ± 0.03 D. The axial length of the eye in children of the primary school group after 12 months of wearing glasses with Stellest lenses signifi cantly increased by an average of 0.28 ± 0.03 mm. This axial growth of the eye correlates with an increase in myopic refraction in the same group of children. In the group of children of senior school age, the growth of PZO was 0.1 ± 0.04 mm. There was an increase in the accommodation reserve, the positive relative accommodation and the relative accommodation in all groups. Conclusions. The study showed that wearing glasses with Stellest lenses helps to reduce the rate of progression of myopia and increase the accommodative functions of the eye, which improves the adaptive capabilities and performance of the visual analyzer in all age groups of schoolchildren
The method for determining intraocular pressure according to keratotopographic indicators
Authors: Ahmetov N. R. , Samoylov A. N. , Usov V. A.
Published: December 2023

Relevance. In most countries of the world, applanation tonometers remain popular, such as the Maklakov tonometer and the Goldman tonometer. When measuring ophthalmotonus, such tonometers receive IOP values indirectly through the cornea, which certainly introduces its own errors into the measurement results. The creation of methods for measuring IOP different from the currently existing ones is relevant. Purpose: to create a new method for determining intraocular pressure without tonometry, based on the indicators of the individual profi le of the cornea with its parameters, indices and autorefractometry data. Materials and methods. Statistical analysis of 16 parameters of a keratotopograph (ALLEGRO Oculyzer, WaveLight Oculyzer II), data of an autorefractometer (TONOREF Nidek device) and data of tonometric intraocular pressure was carried out using a Maklakov tonometer (НГм2-«ОФТ-П») in 500 patients (1000 eyes). Among the sample population there were patients with both emmetropic refraction – 8 eyes (0.8%), and patients with refractive errors 992 eyes (99.2%), among them: 978 eyes (97.8%) had myopic refraction, 14 (1.4%) eyes had isolated refraction with myopic astigmatism. 889 eyes (88.9%) combined myopic refraction with myopic astigmatism. Results. Based on the analysis of keratotopographic parameters, autorefractometry values and tonometric IOP of 500 patients (1000 eyes), we have created a new method for determining intraocular pressure without tonometry, presented in the form of a mathematical model: Pt keratotopographic = 61.9 – 0.06 × SPH – 2.39 × Rf + 0.64 × Rmin – 0.15 × log2 (IVA) – 31.9 × CKI – 0.006 × Thickness. Conclusions. Based on the results obtained for determining IOP without physical interaction with the eye, the mathematical model created by us can be used in cases where the use of any tonometer is impossible.
The correction of a hyperopic astigmatism with full-toric orthokeratology lenses. Clinical case
Authors: Vaseva A. A. , Andrienko G. V.
Published: December 2023

Orthokeratology has gained widespread clinical application in the last decade due to accumulated scientifi c data confi rming its effectiveness in inhibiting progressive myopia in children and adolescents. In cases of correction of other refractive errors, such as hypermetropia, mixed astigmatism, specialists inform patients about the possibilities of orthokeratology lenses (OKL) not often. This clinical case demonstrates the possibilities of customized, full-toric OKL to correct complex hyperopic astigmatism in an 11-year-old child. The patient was observed for several years with complex hyperopic astigmatism in ophthalmological clinics and followed the recommendations of specialists to use eyeglass correction. At the stage of transition from preschool to primary school, the child became shy of glasses and refused to wear them. In search of an alternative method of correction, parents sought advice in the special contact lens practice. The patient underwent a complete ophthalmological examination, including corneal topography. Taking into account the features of refraction and the shape of the cornea, the wishes of the child and parents, we have chosen customized orthokeratology lenses (OKL) with a fully toric design (full-toric) as method of correction. The OKL parameters were calculated by using the RGP Designer program. The lenses were made by OKVision Laboratory (Moscow). The fi tting of customized OKL allowed us to solve several tasks at once: the correction of complex hyperopic astigmatism and the freedom from using correction tools in the daytime. Despite the fact that orthokeratology is not the fi rst-line choice for optical correction of hyperopia, in some cases the method may become the only alternative to glasses and soft contact lenses

Increasing heat transfer in condensation for low surface tension fluid is dominated by using extended area (fin). One of the extended area on pipe is integral fin tube. Designing of integral fin tube should be conducted due to generate optimal condition such as designing fin spacing. Fin spacing has significantly impacted  to heat transfer enhancement. Whereas the material of pipe is copper since has higher heat conductivity than others and fluid working is methanol. To predict optimal geometry of integral fin tube is conducted by using mathematical simulation by dividing area into flooded and unflooded. The active area or unflooded area represents the heat transfer area adn enhancement. In this experiment is found that the optimum fin spasing is 1 mm

Published: December 2023

This study aims to determine the catalytic effect of ZnO on the kinetics of the decomposition reaction of burning solid waste. ZnO catalyst was chosen because it has high mobility and reactivity. samples were prepared and randomly selected consisting of 12 types of inorganic waste and 10 types of organic waste. The research instrument uses (DTA) Differential Thermal Analysis proximate testing. From this test the data in the form of a mass decrease graph will be analyzed descriptively. The description of the data is displayed through the TG-DTG curve and the calculation of the activation energy (Ea) using the fitting model. the DTG curve identifies three peaks indicating the decomposition stages of the three components have different characteristics. The decomposed components are 1. lignocellulosic organic and low stability organic components, 2. Volatile substances from plastic components, 3. hydrocarbon residues and ash reformation. The combustion temperature increases in samples with high catalyst concentrations, but the burnout temperature decreases in samples with high catalyst concentrations. The DTA curve shows the increased reactivity of samples with high catalyst concentrations. Oxidative reactions which are exothermic/external heating increase in samples with high catalyst concentrations. The catalytic effect on the addition of zinc-oxide (ZnO) catalyst concentration to the components showed a decrease in the hydrocarbon component and an increase in the short chain hydrocarbon component. Increasing the concentration of zinc-oxide (ZnO) catalyst in the sample increases the activation energy. However, overall the addition of catalyst concentration in the combustion of organic-inorganic solid waste samples was able to reduce the activation energy at the end of the combustion reaction

Objectives

There is no consensus regarding the optimal choice between single long stent (SLS) and overlapped double short stents (DSS) in patients with acute myocardial infarction (AMI). Therefore, we aimed to compare treatment outcomes among patients with AMI treated with these two different stenting methods.

Methods

In total, 537 patients with AMI from a single tertiary center were categorized into two groups: (1) those who received an SLS (stent length ≥38 mm) (n = 254; 47.3%) and (2) those who received overlapped DSS (individual stent lengths <38 mm) (n = 283; 52.7%). The primary outcome was the incidence of major adverse cardiac and cerebrovascular events (MACCEs) within 1 year.

Results

The mean age of participants was 65.4 years, and 75.0% were male. Patients receiving an SLS had a higher rate of serum creatinine level ≥1.5 mg/dl (16.3% vs. 8.9%, p = 0.009) but a lower rate of hypertension (46.8% vs. 55.8%, p = 0.038), lesser total stent length (38.26 ± 1.31 vs. 45.20 ± 9.25 mm, p < 0.001), total procedure time (41.40 ± 15.74 vs. 53.31 ± 21.75 min, p < 0.001) and total contrast volume (134.13 ± 30.72 vs. 160.57 ± 39.77 ml, p < 0.001) than in those receiving DSS. One-year MACCEs were comparable between the two groups before [hazard ratio (HR), 1.33; 95% confidence interval (CI), 0.80–2.24] and after adjusting for covariates (HR, 1.21; 95% CI, 0.67–2.19).

Conclusions

Stenting with an SLS demonstrated similar outcomes compared to those achieved when using stenting with overlapped DSS in patients with AMI. Therefore, if the deliverability is acceptable, stenting with an SLS appears to be a safe and effective strategy for AMI treatment.

Objective

Red cell distribution width (RDW) and serum calcium (Ca) levels are predictors of in-hospital mortality in acute myocardial infarction (AMI) patients. However, their sensitivity and specificity are limited. Therefore, this study aimed to determine whether the RDW to Ca ratio (RCR) acquired on admission can be used to predict the in-hospital mortality of AMI patients.

Methods

This retrospective cohort study extracted clinical information from the Medical Information Market for Intensive IV (MIMIC-IV) database on 2,910 AMI patients enrolled via propensity score matching (PSM). Prognostic values were assessed using a multivariate logistic model and three PSM approaches. Analysis was performed based on stratified variables and interactions among sex, age, ethnicity, anemia, renal disease, percutaneous transluminal coronary intervention (PCI), coronary artery bypass grafting (CABG), atrial fibrillation, congestive heart failure, dementia, diabetes, paraplegia, hypertension, cerebrovascular disease, and Sequential Organ Failure Assessment (SOFA) score.

Results

A total of 4,105 ICU-admitted AMI patients were analyzed. The optimal cut-off value of the RCR for in-hospital mortality was 1.685. The PSM was performed to identify 1,455 pairs (2,910) of score-matched patients, with balanced differences exhibited for nearly all variables.The patients’ median age was 72 years (range, 63–82 years) and 60.9% were male. The risk of in-hospital mortality incidence increased with increasing RCR levels. After adjusting for confounders, the risk ratio for the incidence of in-hospital mortality for high RCR was 1.75 [95% confidence interval (CI): 1.60–1.94, P = 0.0113] compared to that associated with low RCR in the PSM cohort. High RCR was also substantially implicated in in-hospital mortality incidence in the weighted cohorts [odds ratio (OR) = 1.76, 95% CI: 1.62–1.94, P = 0.0129]. Assessment of RCR in three groups showed that patients with high RCR also had a higher risk of in-hospital mortality (OR = 3.04; 95% CI, 2.22–4.16; P < 0.0001) than in patients with RCR in the adjusted model. In the sensitivity analysis, both the original and weighted groups showed similar results.

Conclusion

The RCR at admission may be useful for predicting in-hospital mortality in ICU-admitted AMI patients.

Introduction

Type 2 diabetes (T2D) is a multifactorial disease involving genetic and environmental components. Several genome-wide association studies (GWAS) have been conducted to decipher potential genetic aberrations promoting the onset of this metabolic disorder. These GWAS have identified over 400 associated variants, mostly in the intronic or intergenic regions. Recently, a growing number of exome genotyping or exome sequencing experiments have identified coding variants associated with T2D. Such studies were mainly conducted in European populations, and the few candidate-gene replication studies in North African populations revealed inconsistent results. In the present study, we aimed to discover the coding genetic etiology of T2D in the Tunisian population.

Methods

We carried out a pilot Exome Wide Association Study (EWAS) on 50 Tunisian individuals. Single variant analysis was performed as implemented in PLINK on potentially deleterious coding variants. Subsequently, we applied gene-based and gene-set analyses using MAGMA software to identify genes and pathways associated with T2D. Potential signals were further replicated in an existing large in-silico dataset, involving up to 177116 European individuals.

Results

Our analysis revealed, for the first time, promising associations between T2D and variations in MYORG gene, implicated in the skeletal muscle fiber development. Gene-set analysis identified two candidate pathways having nominal associations with T2D in our study samples, namely the positive regulation of neuron apoptotic process and the regulation of mucus secretion. These two pathways are implicated in the neurogenerative alterations and in the inflammatory mechanisms of metabolic diseases. In addition, replication analysis revealed nominal associations of the regulation of beta-cell development and the regulation of peptidase activity pathways with T2D, both in the Tunisian subjects and in the European in-silico dataset.

Conclusions

The present study is the first EWAS to investigate the impact of single genetic variants and their aggregate effects on T2D risk in Africa. The promising disease markers, revealed by our pilot EWAS, will promote the understanding of the T2D pathophysiology in North Africa as well as the discovery of potential treatments.
