Authors: Doo J.G. , Min H.K. , Choi G.W. , Kim S.W. , Min J.-Y.
Published: July 2022

Background: The pathogenesis of maxillary sinus fungal ball (MSFB) is explained by aerogenic and odontogenic factors. We evaluated the predisposing factors, including intranasal anatomical and dental factors for increased diagnostic accuracy. Methodology: In this study, 117 patients who underwent endoscopic sinus surgery for unilateral MSFB were included. Preoperative computed tomography (CT) scans were used to analyze the presence of anatomical variations (anterior and posterior nasal septal deviation (NSD), concha bullosa (CB), infraorbital cell (haller cell), paradoxical middle turbinate, everted uncinate process and MS size). Dental factors including history of dental procedures and findings on CT scans were reviewed. Results: Anterior and posterior NSD toward non-affected side were significantly associated with the presence of FB. The presence of CB and infraorbital cell was higher in the non-affected side rather than in the lesion side. Compared to non-affected MS, FB-presence MS was shallower and had a larger height to depth ratio. The presence of dental history was significantly higher on FB-presence MS than non-affected MS. In multivariable analysis, posterior NSD toward non-affected side, dental history increased the aOR of MSFB, while the presence of CB and infraorbital cell decreased the aOR of MSFB. Conclusions: The occurrence of MSFB seems to be associated with ipsilateral odontogenic factors, followed by anatomic variations including posterior NSD toward non-affected side and absence of CB and infraorbital cell.
Evaluación de la variabilidad del ácido fítico, utilizando metodologías de cromatografía, en una muestra diversa de Lupinus luteus L. (Fabaceae)
Authors: Maureira-Butler I. J. , Parra-González L. , Udall J. A.
Published: July 2022

El ácido fítico (AF) es una fuente de almacenamiento de fósforo en plantas y representa ~75% del fósforo (P) total de la semilla. Debido a su capacidad quelante de minerales, AF ha sido descrito como un factor antinutricional en la alimentación de humanos y animales, forzando la suplementación artificial de Pi (fósforo inorgánico) en dietas, y aumentando la contaminación de fósforo a través de desechos animales. Sin embargo, estudios han demostrado efectos positivos sobre salud humana, dada su potencial actividad anticancerígena. Por ello, la identificación de variabilidad en el contenido de AF es de interés para los mejoradores de cultivos. El objetivo principal de esta investigación fue evaluar variabilidad de AF en una muestra diversa de L. luteus. Para ello, se estudió la variación fenotípica de AF en semillas de 18 accesiones, a través de cromatografía de capa fina de alto rendimiento (HPTLC). Perfiles cromatográficos sólo detectaron AF y Pi, sugiriendo que otros intermediarios no se acumularían en esta leguminosa. Análisis de varianza mostraron diferencias significativas para AF y Pi, lo que indicaría que la acumulación de estos compuestos es influida en parte por los genotipos de L. luteus. Los contenidos AF y Pi variaron entre 13,97 a 24,37 mg g-1 y 1,27 a 1,68 mg g-1 (base materia seca), respectivamente. La presencia de variación fenotípica significativa para AF no sólo proporciona información para el descubrimiento de las vías metabólicas envueltas en su síntesis, sino que además identifica variación favorable para la reducción de factores antinutricionales en lupino amarillo.

Authors: Muñoz N. , Concha-Meyer A.
Published: July 2022

El plasma frío atmosférico (PFA) ha generado gran interés en el área industrial y en la comunidad científica, puesto que presenta valiosas propiedades, como lo son su simplicidad operativa, su bajo costo de funcionamiento, y su respeto por el medio ambiente. El PFA se puede generar a partir de varios gases (aire, nitrógeno, helio, argón) y por diferentes métodos. Sus aplicaciones abarcan múltiples áreas, como medicina, electrónica, ciencia de alimentos y agricultura, entre otros. Una de las principales características del PFA, es su capacidad de eliminar microorganismos patógenos, a través de la generación de radicales libres, los cuales disrumpen las membranas de las células y generan su apoptosis. Debido a esto, diversos investigadores han determinado los efectos de tratamientos con PFA sobre diferentes productos alimentarios, de origen vegetal y animal, contaminados con microorganismos patógenos. En general, se ha encontrado que PFA reduce significativamente la carga microbiológica de diferentes alimentos, sin afectar en la mayoría de los casos sus propiedades nutricionales y calidad. Lo que demuestra que el PFA es una herramienta innovadora y eficaz en la utilización para la inactivación de microorganismos en productos alimentarios.

Published: July 2022

The use of remote technology can currently help in the development of studies considering the peculiarities of each environment, such as fish farming. With the increase in demand for fish in recent years, the expansion of productive areas of fish farms has been observed, resulting in greater territorial occupation, most of the time, in a disorganized way. The present work aimed to map the fish areas in the municipality of Santa Inês, Maranhão State. To identify the areas occupied by fish farms, the Photointerpretation Method and its recognition elements were used through the following software: Spring, QGis, Google Earth Pro and Arcview. To validate the information, on-site visits were carried out in fish farms according to the points identified using the software. According to the data obtained, the municipality of Santa Inês - MA showed an evolution in the territorial occupation of fish areas, from 22.99 hectares in 2003 to 46.84 hectares in 2011, 126.95 hectares in 2015 and 141 .86 hectares in 2017, with greater expansion in territorial occupation in the period from 2011 to 2015 (171%), with 81.25% of the mapped areas concentrated within a radius of 3 km from the municipal headquarters. Fish farms in the municipality of Santa Inês corresponded to only 0.24% of the total area of the municipality. The preparation and analysis of thematic maps of the territorial occupation of fish farming can help in the management of the areas found and i

Published: July 2022

Anthologies of oral literature by Vojislav M. Jovanović Marambo, Ser- bian folk poems and Serbian folk tales, represent a significant part of his study of oral literature. Apart from being in accordance with general features of anthologies ‒ reflecting aesthetic criteria of the compiler and the epoch in which they were published, as well as the educational goals ‒ these anthologies largely synthesize Jovanović’s study of oral literature. This paper presents the reception of the anthologies by both scientific circles and the public in the period between the two world wars. Jovanović’s contribution to the folk- loristics is, among other things, reflected in the fact that his anthologies represent one of the first successful attempts, after Vuk, to collect the works of folk literature.

Authors: Govindarajan Narendran , Thirunavukkarasu Raghupathy , Chandran Magesh
Published: July 2022

We present case of a 47 year male, who underwent elective surgical repair for inguinal hernia. During surgery, chyle was unexpectedly found in the hernia sac and abdominal cavity. A thorough diagnostic workup for chylous ascites was performed to rule out pre-existent underlying pathologies, and the patient was temporarily placed on a medium-chain triglyceride diet. No symptoms occurred afterwards. Based on the clinical course and results of additional investigations, this rare phenomenon has most likely occurred due to obstruction and potential rupture of lymphatic structures due to mechanical effects following intermittent incarceration and subsequent repetitive manual reduction of the symptomatic hernia including bowel loops as content of the hernia sac. A search was made and chylous ascites as hernial content was not reported in adults. This is a rare instance.

Published: July 2022

Background: Candidiasis in not uncommon among hospitalized patients. The fungal virulence and antifungal drug resistance make the host-parasite interactions complicated. The threat of azole drug resistance along with scarcity of antifungal therapies prompted the necessity of novel drug development from various natural sources. The objective of this study was to evaluate the anticandidal activity of Coriandrum sativum seed extracts against Candida albicans and Candida tropilcalis.

Materials & Methods: This study was conducted at Department of Basic Medical Sciences, College of Medicine, Prince Sattam Bin Abdulaziz University, Al-Kharj, Saudi Arabia from July 20, 2021 to September 26, 2021. The study analyzed anti-inflammatory assays via inhibition of albumin denaturation and hemolysis inhibition and anticandidal activity of the extract against Candida albicans and Candida tropilcalis by well diffusion method. The minimum inhibitory concentration (MIC) of the extract was also determined against both the fungi.

Results: Anti-inflammatory activity of Coriandrum sativum methanolic seed extracts were evaluated at five different concentrations from 100 µg to 1000 µg. The highest concentration showed 55.31±0.77% of inhibition of albumin denaturation, whereas the aspirin, the standard used, showed 80.33±0.32%. Coriandrum sativum seed extracts at 250 mg/ml, 500 mg/ml and 1000 mg/ml produced zones of growth inhibition with diameters 12.66±0.57, 17.66±0.57 and 24.33±1 mm against Candida albicans, and 10.33±0.57, 16.66±0.57 and 21.66±0.57 mm against Candida tropicalis. The MICs of the Coriandrum sativum seed extracts against Candida albicans was 1.95 mg and Candida tropicalis was 3.9 mg.

Conclusion: Phytochemical compounds in methanolic seed extracts of Coriandrum sativum showed significant anticandidal activity against Candida albicans and Candida tropicalis with highest zone of inhibition at 1000 µg extract concentration. The lower MICs of Coriandrum sativum seed extracts against Candida albicans and Candida tropicalis were also significant. Considering all these findings along with the antioxidant activities, it could be suggested that Coriandrum sativum seed extracts can further be investigated for development of novel anticandidal drugs.

Implementation and adoption of mobile training are still nascent in the public sector in the UAE. A successful migration model for a mobile training system relies on user support and acceptance as well as the decision to migrate to mobile training. The study aims to investigate a comprehensive range of the factors that influence the intention to use and support to change to mobile training in the Sharjah police general command – UAE. The proposed conceptual framework includes Individual Beliefs (attitude) (IB), Facilities Condition (FC), Habits (HA), Intention to Use Mobile Training (IUMT), and support to change to mobile training (SCMT). The study's target population is all the staff members of the General Department of Sharjah Police in the Emirate of Sharjah, which has a total of 7,715 employees and a sample size of 367. The final dataset includes 373 respondents collected from 19 different departments by using the quota sampling technique. Results of intention to use mobile training (IUMT), illustrate a satisfactory predictive power; the three variables; IB, FC, and HA can explain 44.6% of the variance. The precedence of the impacts based on the path coefficient is individual belief, facilitating conditions, then habit. Results of support to change to mobile training (SCMT), illustrate a moderate predictive power; the four variables; IUMT, IB, FC, and HA can explain 63.6% of the variance. The precedence of the impacts based on the path coefficient is the intention to use mobile training, then individual belief. The three main predictors have impacts on the support to change to mobile training (SCMT) either directly or indirectly.

1830 senesinde ticari olarak telgrafın kullanılması ile uzak mesafelere bilgi taşınmasında büyük zorluklar yaşanmıştır. İlk başlarda İngiltere ile Fransa arasında çekilen hat zamanla İngiltere-Amerika Birleşik Devletlerine kadar uzamıştır. Telgraf hattında kullanılan kabloların hammaddesi ve kesitleri ilk başlarda deneme yanılma yöntemleri ile oluşturulmaya çalışılmıştır. Maxwell denklemlerinin bulunmasına istinaden 1800’ lü yılların sonlarına doğru Telgraf Denklemleri ortaya çıkmış olup haberleşme, bilgi iletimi ve benzeri transmisyon hatlarına ait denklemler Telgraf denklemlerinden türetilmiştir. Teknolojinin gelişmesine istinaden, seyrüsefer emniyeti dikkate alınarak tasarlanan Demiryolu taşımacılığı için, sinyalizasyon sistemlerine ihtiyaç duyulmuştur. Demiryolu sinyalizasyon sisteminin faal bir parçası olan ray devreleri, aynı zamanda birer bilgi iletim hattı görevi görmektedir. Modülasyon ve sayısal anahtarlama yöntemlerinin gelişmesi ile ses frekanslı eksiz ray devreleri geliştirilmiş olup ray devresinin alıcı-verici frekansı yükselerek çevresel koşullardan daha az etkilenir hale gelmiştir. Bu makalede gerilim ve akım sızıntıları yönünden benzer olan Telgraf iletimi denklemleri ile demiryollarında kullanılan Ray devresinin bilgi iletimi incelenmiştir.

Published: July 2022

Yük ve yolcu taşımacılığında kullanılan raylı sistem araçlarının (vagon, lokomotif, tren vb.) birlikte hareket edebilmesini sağlayan bağlantı ekipmanlarının genel adı koşum takımıdır. Koşum takımları, araçlara gelen statik yüklerin iletimini sağlamanın yanı sıra elektriksel ve hava bağlantılarının aktarılmasında görevli olup, sistemi oluşturan elemanların tasarımı ve imalatı çeşitli standartlara göre yapılmaktadır. Diğer yandan, lojistik sektöründe daha hızlı ve aynı zamanda güvenli taşımacılık açısından araçları oluşturan tüm parçaların hafifletilmesi önemlidir. Bu çalışmada, minimum ağırlıkta ve yüksek performanslı parçaların tasarımında etkili bir araç olan topoloji optimizasyonu ile koşum takımı elemanlarından üzenginin tasarımı iyileştirilerek ağırlığının azaltılması hedeflenmiştir. Topoloji optimizasyonunda yoğunluk yöntemi olarak da bilinen cezalandırmalı katı izotropik malzeme (SIMP) yönteminden faydalanılmıştır. Öncelikle, standarda uygun olarak modellenen koşum takımı üzengisine 120 kN ve 150 kN yükleme durumları için sonlu elemanlar analizi uygulanmıştır. Daha sonra, topoloji optimizasyonu ile geliştirilen model için aynı şartlarda FEA uygulanarak gerilme dağılımları ve yer değiştirme miktarları karşılaştırılmıştır. Her iki yükleme durumu için en yüksek Von Mises gerilmesi sırasıyla 176,30 MPa ve 220,40 MPa olarak elde edilmiştir. Ayrıca, yeni tasarım üzengiler için en yüksek yer değiştirme miktarları 0,23 mm ve 0,28 mm olarak hesaplanmış olup, bu değerler ilgili standartta belirtilen sınırlar içindedir. Sonuç olarak, topoloji optimizasyonu başarıyla uygulanarak üzenginin kütlesi %9,04 azaltılmıştır. Ayrıca, topoloji optimizasyonu ile geliştirilen model geometrisindeki karmaşıklıktan dolayı üzenginin eklemeli imalat teknolojisiyle üretiminin daha elverişli olduğu kanaatine varılmıştır. Tüm sonuçlar, topoloji optimizasyon metodolojisinin raylı sistem araçlarının ağırlığının azaltılmasında güvenle uygulanabileceğini ve böylece sürdürülebilirliğe önemli katkılar verilebileceğini göstermektedir.

Published: July 2022

Grafting in species of Pinus is used to establish asexual seed orchards. Generally, grafting success is low, therefore, it is required to study the influencing factors. Such as the technique and the contact surface of the cambium that depends on the length of the cut on the scion and the rootstock. The objective of this study was to evaluate graft success, growth, and needle development on Pinus patula grafts as functions of the grafting technique and cutting length. It was expected that a specific combination of technique and cutting length would allow predicting the graft success. The techniques of top cleft, side-veneer and splice grafting were used with three cutting lengths (1.5, 2.0, and 2.5 cm) in a completely randomized design with factorial array. The data were analysed with an analysis of variance and treatment means were compared with the Tukey test (p ≤ 0.05). Sixty days after grafting, technique influenced success; top cleft grafting had the highest value (80%) but was not statistically different from side veneer grafting (73.3%). There was, however, statistical difference between top cleft and splice grafting (56.7%, p ≤ 0.05). There were no differences among the three cutting lengths in terms of the three variables evaluated. The effect of the interaction showed that top cleft and side veneer grafts with the cutting length of 1.5 cm expressed the greatest growth (32.4 and 32.2 mm, respectively); followed by side veneer grafting with the cutting length of 2.0 cm (30.4). The study demonstrated that the most viable techniques to increase grafting success in P. patula are the top cleft and side veneer techniques. Cutting length of the scion and the rootstock can be set within the range 1.5 to 2.5 cm

Authors:   B. Sc, Civil Engineering, Alfalah University, Jalalabad City, Nangarhar, Afghanistan, Pashtoon Muhammad Israr
Published: July 2022

Cement plays a vital role in concrete production; as a binding agent, it holds together the aggregates in concrete. Manufacturing of cement and glass causes depletion of natural resources and endangerment of the environment. Both the glass and cement industries are energy consumers and are responsible for hazardous greenhouse gases, particularly and nitrogen oxides. The contribution of the cement industry toward emissions is 5% globally, and it is estimated that one ton of cement production produces 0.9 to 1 ton of . The rising population rate, which is a concern today, necessitates proper construction and infrastructure. This leads to more production of cement and glass and as a result, millions of tons of glass waste are produced every year globally and deposited directly into landfills without being recycled. The global Waste Glass (WG) production was estimated to be over 130 million tons in 2005. Because of its non-biodegradable nature, it is a huge burden on landfills, especially in metropolitan areas. At the same time, it exhibits pozzolanic behavior in finely ground form. To overcome these problems and to use them as a source, the concrete industry provides a better solution. Adaptation were taken to use it as an out of the ordinary to cement in concrete and examine its effects on concrete in both fresh and hardened states. According to the study, the mechanical characteristics of Waste Glass Powder (WGP) concrete are influenced by particle size and percentage replacement. This review is aimed at studying glass powder concrete.

La agenda para América Latina del Secretariado Internacional de la Liga Comunista Internacionalista (trotskista)
Authors: Schelchkov Andrey
Published: July 2022

[Artículo evaluado por pares]

En los treinta, los grupos comunistas disidentes vinculados a León Trotsky se organizaron en la Oposición Internacional de Izquierda. Ello hizo necesario un órgano de coordinación: el Secretariado Internacional (SI) se encargó de formar el movimiento trotskista internacional y luego la IVª Internacional. Con escasos recursos financieros y un admirable esfuerzo, el SI buscó montar un movimiento de alcance mundial que competiera con la gigante y stalinista Komintern. El artículo analiza la agenda para Latinoamérica del SI. Su base documental es el Archivo Henk Sneevliet. Éste es resguardado en el archivo moscovita RGASPI y abarca de 1932 a 1936, años en que Sneevliet fue secretario del SI. La hipótesis del artículo es que el SI fracasó en la unificación del movimiento trotskista porque se empeñó en eliminar la heterogeneidad ideológica y política de los grupos desde una voluntad centralizadora heredada de la intolerancia del bolchevismo y la Komintern.
