Published: December 2024

Objective: Hepatic steatosis and gallstones are common in the general population, with risk factors being multifactorial. Experimental studies have shown that cholecystectomy increases hepatic steatosis and leads to non-alcoholic fatty liver disease (NAFLD). In order to evaluate this, the current study was carried out in the department of general surgery at a medical school, in the north of India.

Material and Methods: One hundred and three patients awaiting cholecystectomy were selected after written informed consent. Their baseline characteristics were captured preoperatively and thereafter followed at 3rd month with liver function test (LFT), lipid profile and ultrasound (USG) abdomen.

Results: Average age of the patients enrolled was 41.62 ± 13.62 years and mean body mass index (BMI) was 25.96 ± 1.73 kg/m2 . Total bilirubin (0.56 vs 0.76, p< 0.0001) and direct bilirubin (0.15 vs 0.27, p< 0.0001) decreased significantly post cholecystectomy as compared to preoperative values. Levels of serum glutamic-oxaloacetic transaminase (SGOT) (49.14 vs 34.98 IU/dL), serum glutamic-pyruvic transaminase (SGPT) (50.85 vs 35.46 IU/dL) and alkaline phosphatase (ALP) (101.16 vs 85.97 IU/dL) increased significantly post-surgery. Cholesterol values (146.28 vs 168.77 mg/dL), triglycerides (TGs) (119 vs 133.56 mg/dL), low density lipoprotein (LDL) (93.32 vs 113.05 mg/dL) and very low density lipoprotein (VLDL) (18.68 vs 27.45 mg/dL) decreased significantly while high density lipoprotein (HDL) (48.96 vs 42.42 mg/dL) increased significantly at three month follow-up. Prevalence of fatty liver increased post operatively with a rise in Grade 1 steatosis (75%). Severity of fatty liver increased with (8.73%) Grade 3 steatosis on USG post-surgery. Hence, new patients with formerly normal USG reports developed fatty liver and those with preexisting liver steatosis seemed to worsen.

Conclusion: The study concluded that the prevalence of fatty liver increased post-cholecystectomy. Lipid profile parameters improved favorably with a decline in total cholesterol, TG, LDL and VLDL versus increase in HDL. LFT parameters also changed significantly.

Objective: Non-operative management of abdominal gunshot injuries has become the standard care in the selected cases of modern surgery with an acceptable success rate to reduce the incidence of unnecessary laparotomies. In this study, an assessment was conducted to determine how the success of this form of management was impacted by physical examination and radiological investigation.

Material and Methods: This is a retrospective study that includes all consecutive penetrating abdominal gunshot wound patients who were admitted to the emergency department between February 2011 and December 2018. All patients with superficial gunshot wounds were excluded. The decision to perform a laparotomy on injured patients was the study’s primary endpoint while the discharge of patients without surgery was its secondary endpoint.

Results: Of 429 torso gunshot wound patients, 411 were males. Average age was 29.5 years. Forty-one (9.5%) were initially treated by selective nonoperative management. Five selective non-operative management patients underwent delayed laparotomy within 12 hours after admission without complication. In the end, 36 (88%) of the 41 patients were successfully treated without undergoing surgery, with only one patient developing pleural effusion and no mortality attributed to it. Of all injured patients, 45 (10.5%) patients had a negative laparotomy, with two of them subsequently developing an incisional hernia.

Conclusion: The success rate of non-operative management of torso gunshot injuries can be increased significantly in stable patients by adopting the strategy of repeated physical examinations alone or in conjunction with simultaneous radiological imaging.

Authors: Z. B Agyo, , D. T Wake,
Published: December 2024

This study assessed the measures in resolving incessant herdsmen-arable crop farmers’ conflicts on rural and agricultural development among farmers in Plateau and Taraba States, Nigeria. The population of this study consisted of arable crop farmers in Taraba and Plateau States. Stratified, purposive, and simple random sampling techniques were used to select 252 respondents as the sample size. Data for the study were collected from primary sources with the use of structured questionnaires and were analyzed with the use of inferential statistics such as Kruskal-Wallis. The Kruskal-Wallis (H) test revealed that there was a significant difference (P>0.05) between Plateau and Taraba States in terms of H. Cal. (27.5) > X2 Tab (11.1) at 0.05 level of probability, hence the null hypothesis was rejected, and the alternative hypothesis was accepted. It was concluded that each State put in place different measures in resolving incessant herdsmen-arable crop farmers’ conflicts on rural and agricultural development. In Plateau State, the adoption of ranching (69), anti-open grazing law (68), government intervention (66), payment of compensation to farmers (62), and educating parties involved (60). In Taraba State, it was found that anti-open grazing law (77), respect for culture and tradition (75.5), adoption of ranching (75.5), personal intervention with village heads and heads of herdsmen (73), dialogue with the parties involved (73) were the most serious measures needed to put in place to resolving herdsmen-arable crop farmers’ conflicts. The study, therefore, recommended that there should be good government policy on open grazing, there should be control of the immigration of foreign Fulanis into Nigeria, ranching should be encouraged, and the Land Use Act policy should be fully implemented.

Published: December 2024

Computer-Based Examination (CBT) represents a growing trend in the assessment of knowledge and skills, utilizing computer technology to address many of the challenges associated with traditional, human-supervised examinations. These challenges include collusion, impersonation, unauthorized external assistance, and peeking. The research developed a comprehensive system that incorporates iris and voice recognition technologies to significantly reduce these problems, thereby enhancing the security, integrity, and reliability of the computer-based examinations. The system consists of the CBT module and the monitoring module. The CBT module includes a network infrastructure with a central server and several network-controlled workstations. The monitoring module was designed to monitor candidates in real-time and features an iris scanner that intermittently captures and analyzes the candidate’s iris, triggering warnings or punitive actions if the system detects Behaviour such as peeking beyond a permissible range or other iris-related infractions. It also includes a voice processor that intermittently captures the candidate’s audio signals, with similar consequences for violating audio intensity rules. The experimental study on the practical function of the system established its suitability for curtailing iris and voice-related infractions during CBT and the minimization of the costs associated with the screening, control, and management of CBT candidates.
Italia y Valencia en la pintura de Joan de Borgonya (doc. 1496-1525). Modelos y contextos para la Natividad del Museo de Bellas Artes de Valencia
Authors: Alberto Velasco González
Published: December 2024

Resumen
 
Joan de Borgonya es una de las figuras clave de la pintura del Renacimiento en la Corona de Aragón. Se desconoce el origen del pintor, pero se le supone una formación en el área germánica meridional, en la región del Danubio. Aunque su peripecia profesional es conocida desde que se instaló en Valencia en 1496 y del posterior traslado a Cataluña hacia 1508, no se tienen datos sobre qué hizo antes de llegar a la Corona de Aragón. Partiendo del análisis de La Natividad conservada en el Museo de Bellas Artes de Valencia, así como de dos obras más del Museu Nacional d’Art de Catalunya, La Virgen del Mono y La Anunciación, el presente estudio incide en aquellos aspectos que conectan a Borgonya con la pintura desarrollada en Padua y Venecia, unos vínculos que nos llevan a defender una estancia del artista en el Véneto hacia 1485-1495. En paralelo, y a través de las semejanzas de las tres pinturas mencionadas con modelos también italianizantes de Paolo de San Leocadio y el taller de los Osona, proponemos que dichas obras fuesen realizadas durante los primeros años del artista en Valencia.

Abstract
 
Joan of Borgonya is one of the key figures in Renaissance painting in the Crown of Aragon. The painter’s origins are unknown, but it is assumed that he trained in the southern Germanic area, in the Danube region. Although his professional career is known from when he settled in Valencia in 1496 and his subsequent move to Catalonia around 1508, there is no information on what he did before arriving in the Crown of Aragon. Based on the analysis of The Nativity preserved in the Museo de Bellas Artes de Valencia, as well as two other works from the Museu Nacional d’Art de Catalunya, The Virgin of the Monkey and The Annunciation, this study focuses on those aspects that connect Borgonya with the painting developed in Padua and Venice, links that lead us to argue that the artist stayed in Veneto around 1485-1495. In parallel, and through the similarities of the three paintings mentioned with the also Italianate models of Paolo da San Leocadio and the Osona workshop, we propose that these works were made during the artist’s first years in Valencia.

Reasons for emigration from Africa: A recent analysis on Cameroon
Authors: Maliki Usmanu , Göktürk Baltas Gülen
Published: December 2024

One of the biggest issues facing humanity in the current century is mass migration from the developing to the industrialized world. While some migrations are legal, many others are not, which poses danger and risk, and are frequently fatal. In Sub-Saharan Africa, emigration through Libya tremendously increased after 2011 following the collapse of Qaddafi’s government, which led to civil war and the absence of a powerful government to enforce law and order in the country. Even though thousands of migrants die every year trying to cross the Mediterranean into Europe, many African youths still scramble to emigrate from the continent using both legal and illegal means. This study analyses how economic hardships and political instability act as push factors for emigration from Cameroon, as well as the risks faced during the emigration process. The paper also addresses the challenges faced by Cameroonian immigrants in their host country and the socioeconomic impact of emigration on Cameroon and concludes that push factors are more influential than pull factors in driving irregular immigration from Cameroon.

Through the Students Lens: Comparing effectiveness of Face-to-Face vs. Online Learning of Undergraduate Medical and Dental Students in Islamabad, Pakistan
Authors: Ali Sarah , Farooq Naveen
Published: December 2024

Objective: To get an insight from the undergraduate medical and dental students regarding the effectiveness of online vs. face-to-face learning in terms of increasing knowledge, clinical skills and social competency.
Methodology: A cross-sectional descriptive study in which 391 students of a private medical and dental college in Islamabad participated from September, 2023 till December, 2023. Study participants were selected using consecutive sampling technique. Data was collected using a structured questionnaire that was adapted from a published study. Summary statistics for continuous variables and percentage and frequency was computed for categorical variables. Wilcoxon signed-rank test was used for comparisons between online and face-to-face learning.
Results: There were 33.2% male and 66.8% female students. The mean age of the participants was 20.75±1.57. Face to face learning was more effective in increasing knowledge as compared to online teaching (p =0.001). Similarly, Face to face learning was more effective as compared to online learning in increasing practical/ clinical skills and social competency (p =0.000). A majority of students (61%) reported that the primary advantage of online learning is the convenience of accessing education from home without the need to travel. This is a well-known benefit of online learning. The most significant disadvantage, cited by 70% of students, was technical or internet problems.
Conclusion: In conclusion, this study underscores the inadequacy of online learning alone in terms of increasing knowledge, clinical skills and social competency among medical and dental students. Our findings clearly demonstrate that face-to-face or blended teaching methods are essential for fostering comprehensive learning experiences that include hands-on practice, interactive learning environments, and the development of clinical skills.

Published: December 2024

Porang tubers (Amorphophallus muelleri Blume) are known as konjac in Indonesian prominent glucomannan sources. The research objective is to compare the dry and wet extraction methods. Two extraction methods (dry and wet) were carried out. First, porang flour was obtained from a centrifugal grinder and purified twice with 70 % ethanol solution for 2 h, respectively. Next, the sample was milled with ethanol solution and precipitated twice with 70 % ethanol solution. The 2 samples were compared to a konjac commercial glucomannan for physicochemical and molecular properties. The study revealed that the physical characteristics of glucomannan extracted through the wet method significantly differed from those obtained via dry extraction and the commercially available Konjac glucomannan. Specifically, the glucomannan from dry extraction demonstrated poorer physical qualities compared to its wet-extracted counterpart, and even more so when compared to commercial Konjac. The wet-extracted porang glucomannan’s viscosity (33,000 cPs) and whiteness level (70.04) were markedly different from the commercial Konjac, which had a viscosity of 39,000 cPs and a whiteness level of 83.17. In contrast, the dry extraction method yielded lower values, with a viscosity of 22,000 cPs and a whiteness level of 63.43. While FTIR, XRD and DSC analyses produced similar results across the board, the thermal properties of the wet-extracted porang glucomannan displayed a higher resistance to decomposition compared to the other 2 samples.
HIGHLIGHTS

Reliable and economical technique production of glucomannan
Glucomannan obtained through wet extraction methods is of higher quality compared to that obtained via dry extraction.
The molecular characteristics of konjac glucomannan and glucomannan extracted from wet porang are remarkably similar.
Konjac glucomannan and glucomannan from wet porang exhibit comparable solubility profiles.
The viscosity levels of glucomannan derived from wet porang align with the food industry’s standards.

Published: December 2024

Amasya Kızlar Sarayı, antik dönemden itibaren kralların yönetim ve ikamet merkezi olmuştur. Saraydan günümüze kalan tek yapı Küçük Hamam ile ilgili mimari tasvir dışında araştırma yapılmamıştır. Hamamın inşa tarihi ve bânîsi belli değildir. Aralık mekânının geçiş öğesi olarak kullanıldığı örneklerinden 15. yüzyıla tarihlemek mümkündür. Hamam, Osmanlı ve Selçuklu genel hamam şemasına uymaz. Saray, kale, kervansaray, köşk yapılarda benzerleri görülen özel hamam olarak inşa edilmiştir. Küçük Hamam’ın soyunmalık ve külhan dışındaki mekânları (aralık, ılıklık, tuvalet, sıcaklık) büyük oranda korunmuştur. Çevresindeki ana mekânlara eklentili yapı elemanları, büyük bir kompleksin parçası olduğunun göstermektedir. Malakârî teknikte yapılmış renkli sıva silmeleri, tuğla taşırmalar özgün dönemde hamamın gösterişli olduğunu kanıtlamaktadır. Hamamda Osmanlı ve Selçuklu hamamlarında kullanılan alttan ısıtma sistemi yerine, sıcak su buharının beden duvarlarından dolaştırılarak ısıtıldığı bir sistem kullanılması, özel bir hamam olduğunun göstergesidir. Kızlar Sarayı önemli turizm alanı, ziyaretçilerin Amasya’da uğrak noktalarındandır. Son 250 yıllık süreçte atıl vaziyette bulunan hamamın özgün durumuna en az müdahale ile onarılıp yeni bir işlevle birlikte kullanılmalıdır.
Selanik'teki Azize Ekaterini Kilisesi Çinileri

Published: December 2024

Bu çalışma, Selanik’teki Azize Ekaterini Kilisesi’nin çinilerini incelemektedir. Dendrokronolojik analiz sonuçlarına göre 13. yüzyılın sonunda veya 1315 yılında inşa edilen kilise, tuğla süslemeleri ve çinileri ile Geç Dönem Selanik kiliseleri arasında öne çıkar. Ancak Selanik'in Geç Bizans Dönemi kiliselerinde çinilere rastlanmaz. Azize Ekaterini Kilisesi’nin çinileri yapının doğu cephesine ek olarak kuzey ve güney duvarlara dağıtılmıştır ve toplamda on üç pano vardır. Çiniler ince sgraffito tekniğiyle üretilmiştir. Hamur rengi, kilise ambulatoryumunun duvarlarında kullanılan tuğlalarla aynıdır. Bu durum, çinilerle ambulatoryum duvarlarında kullanılan tuğlaların aynı atölyede hazırlandığını düşündürmektedir. Çinilerin renk paletinde sarı ve yeşil olmak üzere iki farklı tonda sır kullanılmıştır. Çiniler sürekli çevresel etkilere maruz kalmaları nedeniyle bozulma göstermektedir. Genel olarak kare veya dikdörtgen formlu panolarda dairesel madalyonlar içinde dört kollu rozet, altı yapraklı çiçek /rozet motifleri; iki örnekte eş kollu haç motifi; bir örnekte ise sağa dönük stilize edilmiş kuş figürü ile birlikte dört kollu rozet süsleme öne çıkmaktadır. İki panoda, ana desenin çevresini saran iç içe geçmiş iki daire şeklinde işlenen madalyonlar arasında zikzak motifleriyle dolgu yapılmıştır. Çiniler, Bizans Sanatı’nda en sık rastlanan motiflerle bezenmiştir.

The article deals with the development of a technological flowchart of inclined deposits with the angle of incidence of 20-35 degrees by the example of the Zhilandy deposit. The values of the main compressive and tensile stresses were determined depending on the mining depth. The parameters of barrier and inter-chamber pillars were calculated taking into account the depth of development, the thickness and the ore deposit angle of incidence, the complexity of the mining and geological conditions of development, the physical and mechanical properties of rocks, fracturing and the structure of the enclosing rocks. The permissible parameters of the stope and the inter-chamber pillar were determined depending on the angle of occurrence. It was established that an inter-chamber pillar of a classical vertical shape as permissible only if the angle of incidence of the ore body was within 25 degrees; in the other cases, the rock massif is unstable and the probability of collapse of the inter-chamber pillar is very high

Кен орнының игеру тереңдігін, қуаты мен құлау бұрышын, игерудің тау-кен-геологиялық жағдайларының күрделілігін, тау жыныстарының физикалық-механикалық қасиеттерін, жарықтар мен сыйымды жыныстардың құрылысын ескере отырып, тосқауыл және камерааралық бүтіндіктердің параметрлерін есептеу жүзеге асырылды. Тазарту камерасының және камерааралық тұтастықтың рұқсат етілген параметрлері пайда болу бұрышына байланысты анықталды. Классикалық тік форманың камералық тұтастығы кен денесінің құлау бұрышы 25 градусқа дейін болған жағдайда ғана рұқсат етілетіні анықталды, қалған жағдайларда тау жотасы тұрақты емес және камералық тұтастықтың құлау ықтималдығы өте жоғары

Статья посвящена разработке технологической схемы отработки наклонных залежей с углом падения 20-35 градусов на примере Жиландинского месторождения. Определены величины главных сжимающих и растягивающих напряжений в зависимости от глубины отработки. Осуществлен расчет параметров барьерных и междукамерных целиков с учетом глубины разработки, мощности и угла падения рудной залежи, сложности горно-геологических условий разработки, физико-механических свойств пород, трещиноватости и строения вмещающих пород. Определены допустимые параметры очистной камеры и междукамерного целика в зависимости от угла залегания. Установлено, что междукамерный целик классической вертикальной формы допустим только в случае, если угол падения рудного тела находится в пределах до 25 градусов, в остальных случаях горный массив не устойчив и вероятность обрушения междукамерного целика весьма велика

The article presents the results of research aimed at optimizing the performance of the «drilling and blasting – crushing complex» system. It provides an analysis demonstrating the mismatch between blasting results and the crushing of ore material, using the «Pustynnoe» mine as an example. It was found that the particle size distribution of the ore material does not allow for the efficient execution of the energy-intensive crushing process. To improve and optimize the performance of the «drilling and blasting – crushing complex» system, it is proposed to zone the blasting areas within the deposit based on the strength and structure of the rock mass. Models of optimal interaction between the system’s elements have been developed, enabling a significant improvement in the particle size distribution of the fragmented ore, an increase in productivity, and the optimization of the crushed product’s particle size for processing operations

The mining industry is the most important industry in our country, given the abundance of minerals. Most of the most important minerals are found in rocks, often deeply located, which complicates the extraction process. Modern air compressors used in the mining industry must have a high margin of safety when operating in diffi cult conditions: these are uneven terrain, high temperature diff erences, and work underground. This study investigated the technological scheme of the gas pumping process, calculated the compressor, and created a model of the system using MATLAB. The dependence of the compressor outlet pressure on the rotor speed of the motor was identifi ed

Горнодобывающая промышленность – самая важная отрасль в нашей стране, учитывая обилие полезных ископаемых. Большинство наиболее важных полезных ископаемых находятся в горных породах, часто глубоко расположенных, что затрудняет процесс добычи. Современные воздушные компрессоры, используемые в горнодобывающей промышленности, должны иметь высокий запас прочности при работе в сложных условиях: это неровный рельеф, высокие перепады температур, работа под землей. В рамках работы была исследована технологическая схема процесса перекачки газа, рассчитан компрессор и создана модель системы в программе MATLAB. Была выявлена зависимость давления на выходе компрессора от оборотов ротора двигателя

Este artículo busca generar interés en los dibujos de los arquitectos sevillanos del siglo XVII, destacando su importancia y valorando los pocos conservados. Los objetivos principales son la recopilación y el análisis de trazas de arquitectura doméstica en Sevilla y los procesos gráficos vinculados, centrándose en las del arquitecto Pedro Sánchez Falconete. Primero, se han consultado archivos históricos y la Biblioteca Nacional de España. En segundo lugar, se han seleccionado cuatro trazas de Falconete del Archivo de la Catedral de Sevilla, dos de las cuales poco conocidas son analizadas por primera vez (bodegas en Villalba del Alcor, 1628), y se plantea la autoría de dos más (mesón sevillano del Santo Cristo, 1603-1604). Finalmente, se han analizado y comparado con otras contemporáneas, exponiendo procedimientos gráficos, precisión en las medidas y el estado de conservación de los inmuebles.
“The Siting of Buildings”: una investigación de Alison Smithson sobre el emplazamiento topográfico en el mundo antiguo.
Authors: Casino Rubio David
Published: December 2024

La exploración en directo de las ruinas clásicas permitió a Alison y Peter Smithson adentrarse en el conocimiento de sus mecanismos de implantación en el territorio. De la mano de las teorías, primero de Martienssen y posteriormente de Scully, estos arquitectos ingleses examinaron, durante más de 25 años, las antiguas  ciudades griegas y romanas repartidas por diferentes lugares del Mediterráneo, desvelando la importancia que poseía el paisaje en la configuración de sus trazas. Este artículo explora esta profunda incursión en el mundo antiguo a través de un proyecto inédito realizado por Alison en los años finales de su trayectoria, titulado “The Siting of Buildings”. Este trabajo, formado por un extenso conjunto de sugerentes textos, dibujos y fotografías, revela la fascinación que los Smithson sintieron por el emplazamiento topográfico: una “maravillosa e instintiva” forma de implantación que descubrieron en las huellas clásicas y que contribuyó a fortalecer su convicción en una arquitectura íntimamente vinculada a las condiciones específicas del emplazamiento.
El proyecto de representación gráfica como estrategia de puesta en valor del conjunto de espacios subterráneos patrimoniales de Carmona
Authors: Galera-Rodríguez Andrés , Pinto-Puerto Francisco , Algarín-Comino Mario
Published: December 2024

Una de las peculiaridades de los espacios e infraestructuras subterráneas es el quedar ocultos dentro de grandes masas pétreas, sin un correlato masivo exterior. El límite entre espacio y masa es la propia superficie excavada donde percibimos la textura pétrea o terrena. En cuanto a su consideración patrimonial, son espacios creados en el terreno para cumplir un fin específico que complementa a las estructuras emergentes. Su construcción en muchos casos es sustractiva, una singularidad tipológica, que los sitúa a medio camino entre su calificación como edificios patrimoniales, como elementos infraestructurales o como yacimientos arqueológicos. Estas singularidades hacen que su representación, documentación y análisis gráfico sean complejos, y muchas veces infructuoso. Por ello este ­ofrecer estrategias y metodologías que contribuyan, a través de recursos gráficos digitales e impresiones 3d, a la correcta documentación, visualización de espacios con geometría irregular y compleja, con el objetivo de favorecer su análisis, conservación, difusión y puesta en valor.
