Published: October 2023

Tuberculosis is a chronic granulomatous infection caused by Mycobacterium tuberculosis. Since the 80’s, new cases have been increasing especially in developed countries because of spreading of HIVinfection, immunodeficiency and immigration phenomenon. Cervical lymphadenitis is the most frequent localization of extrapulmonary tuberculosis. Clinical manifestations consist in a slow growth and painless swelling of a single or multiple neck nodes, generally unilateral, with rare manifestations of fistulization and of systemic symptoms. Diagnosis is performed by fine-needle aspiration cytology (FNAC) or excisional biopsy integrated by Ziehl-Neelsen stain and Mycobacteria culture. A 57-year-old male patient affected by a right-side large laterocervical swelling. The patient referred that almost one month before he noted the onset of the lesion sizing about 1 cm, so he treated it with antibiotic association of amoxicillin and clavulanate acid without any improvement. The lesion quickly doubled its size, became painful and hyperemic the skin above it. Because of the clinical worsening, the patient undergone to neck ultrasonography that showed a neck mass sizing about 50×25 mm. He began a new antibiotic therapy with Ceftriaxone intra muscle, with no modifications of the lesion. Few days later his clinical conditions drastically got worse - increasing pain and skin fistulization. So he practiced a magnetic resonance imaging of the neck that showed a massive suppurated lesion of the neck. The patient was hospitalized in our Otolaryngology Unit where he began a diagnostic iter in order to clarify the nature of the lesion and differentiate between neoplastic/lymphoproliferative lesion and an infective one. After a biopsy of the lesion, the hysthopatologic examination reported the presence of dense mononuclear cell infiltrate surrounding a set of Langerhans cells, so our diagnostic suspect was addressed to extrapulmonary tuberculosis. The authors report a case of a healthy man without risk factors for tuberculosis infection, come to our attention with a large and aggressive unilateral tubercular cervical lymphadenitis, skin fistulization and no systemic symptoms. To make diagnosis of tubercular lymphadenitis, we sustain that biopsy is still the gold standard if FNAC is in doubt.

Authors: Chahine Elias B. , Nunez-Medina Ricardo M. , Williams Kiara , Kuretski Jennifer , Maarsingh Harm
Published: October 2023

Background Advances in antiretroviral therapy (ART) enable people with HIV to live longer, healthier lives. However, older people with HIV (OPWH) are more susceptible to long-term toxicity and drug interactions associated with ART. Racial and ethnic minorities have specific
social determinants of health, which increase their risks of negative outcomes. Objective To determine if there were differences in the safety and effectiveness of ART in White, Black, and Hispanic OPWH. Methods A retrospective observational study was
conducted on patients receiving care between January 1, 2017, and December 31, 2022, at two affiliated HIV clinics in South Florida. The primary effectiveness endpoint was the percentage of OPWH with undetectable viral load (< 50 copies/mL) throughout the study. Secondary safety endpoints
were changes in median metabolic, hepatic, and renal parameters. A two-way analysis of variance or the Chi-square test was used to determine differences between groups. Results A total of 116 White, 42 Black, and 40 Hispanic OPWH were included. Upon enrollment, most patients
(90.7%) were receiving ART. Of these, the percentage with undetectable viral load was lower among Black (61.8%) compared with White (85.8%; P < 0.01) or Hispanic (83.3%; P < 0.05) patients. Similarly, throughout the study after the first visit, the percentage with undetectable
viral load was lower among Black (61.6%) compared with White (84.7%; P < 0.05) or Hispanic (83.3%; P = 0.12) patients. However, there were no significant differences in the percentage of virally suppressed (< 200 copies/mL) participants throughout the study after the first
visit between Black (88.5%), White (94.9%), and Hispanic (96.7%) patients. Additionally, no significant changes in safety endpoints were observed among the groups throughout the study. Conclusion Fewer Black OPWH had undetectable viral load upon enrollment and throughout
the study compared with White or Hispanic OPWH, suggesting the need to provide more targeted interventions for Black patients.
Minimally invasive surgery for post cholecystectomy biliary stricture: current evidence and future perspectives
Authors: Kalayarasan Raja , Sai Krishna Pothugunta
Published: October 2023

Postcholecystectomy bile duct injury (BDI) remains a devastating iatrogenic complication that adversely impacts the quality of life with high healthcare costs. Despite a decrease in the incidence of laparoscopic cholecystectomy-related BDI, the absolute number remains high as cholecystectomy is a commonly performed surgical procedure. Open Roux-en-Y hepaticojejunostomy with meticulous surgical technique remains the gold standard surgical procedure with excellent long-term results in most patients. As with many hepatobiliary disorders, a minimally invasive approach has been recently explored to minimize access-related complications and improve postoperative recovery. Since patients with gallstone disease are often admitted for a minimally invasive cholecystectomy, laparoscopic and robotic approaches for repairing postcholecystectomy biliary stricture are attractive. While recent series have shown the feasibility and safety of minimally invasive post-cholecystectomy biliary stricture management, most are retrospective analyses with small sample sizes. Also, long-term follow-up is available only in a limited number of studies. The principles and technique of minimally invasive repair resemble open repair except for the extent of adhesiolysis and the suturing technique with continuous sutures commonly used in minimally invasive approaches. The robotic approach overcomes key limitations of laparoscopic surgery and has the potential to become the preferred minimally invasive approach for the repair of postcholecystectomy biliary stricture. Despite increasing use, lack of prospective studies and selection bias with available evidence precludes definitive conclusions regarding minimally invasive surgery for managing postcholecystectomy biliary stricture. High-volume prospective studies are required to confirm the initial promising outcomes with minimally invasive surgery.

Published: October 2023

This research sought to explore the barriers to the retention of girls in school at the basic level in the Amasaman Circuit in the Ga West Municipality of the Greater Accra Region of Ghana. It focused on the background characteristics of girls who drop-out from schools and the causes of school drop-out among girls in the Amasaman Circuit. The study adopted both quantitative and qualitative approaches (mixed method). The specific method adopted by the study was concurrent nested. The purposive sampling and snow balling methods were used to select 30 drop-out girls, 60 regular pupils, 12 parents of drop-outs, 12 parents of regular pupils, 12 teachers from selected schools, 4 assembly members and one officer from the girl-child of the Ga West Municipality for the study. The main instruments used to collect data were interviews and academic records. Both descriptive and inferential statistics were used to analyse data. It was realized that the major barriers affecting retention of girls in school include teenage pregnancy and financial problems. The study recommends that stakeholders should establish mechanisms to prevent teenage pregnancies in basic schools since it is the main cause of school dropouts among girls.

Published: October 2023

The study investigated bank erosion and accretion of the lower section of the Pra River of Ghana using a topographical map of 1974 and satellite imagery of 2007, 2015, and 2018 which was augmented by field observation and key informant interviews. Bankline changes due to erosion and accretion and the total volumetric change in river channel were measured using Remote Sensing and Geographic Information System approaches. The study showed that erosion was more pronounced in both the right and left bank as compared to accretion. The study revealed that bank width area of the lower basin of Pra River increased by 50.7 m² from 16.2 m² in 1974 to 66.9 m² in 2018 eroding large portions of land along the right and left banks of the river. In general, the number of erosional spots in selected cross sections exceeded that of deposition. Erosion took place in 13 spots out of 20 spots constituting 65% with a rate ranging between 0.2 and 3.4 m/year. This research showed the value of channel morphological analysis as it brought to the fore, a quantitative perspective to bank erosion and accretion processes of fluvial systems.
Effect of Solid Waste Disposal on Chemical Quality of Groundwater in Ife North Local Government Area, Osun State, Nigeria: A GIS-Based Assessment
Authors: Nwaezeigwe Joy , Babatunde Timothy
Published: October 2023

Indiscriminate waste disposal is a major environmental challenge in developing countries, especially as thewastes often end up downstream. The present study investigated the vulnerability of selected groundwatersources in semi-rural communities in Ife North Local Government Area of Osun State, Nigeria, tocontamination by adjacent waste dumpsites. The specific objective was to assess the chemical quality of thegroundwater in the area. Data used were results of the laboratory investigation of selected water samplesfrom sampled groundwater sources and information about the uses of the groundwater by the residents. Theparameters pH, conductivity, and TDS were assessed in situ and chemical parameters such as Lead, Iron,Copper and Sulphate were assessed in the laboratory. Results showed that the groundwater sources close tothe dumpsites were more contaminated than the sources farther from the dumpsites. At distances less than50m to the dumpsites, the concentration of the chemical metals did not meet the WHO standard, however, itdecreased with distance from the dumpsite. For instance, although sulphate concentration was below therecommended maximum, sulphate concentration decreased with distance from the dumpsite. The studyconcluded that groundwater sources around dumpsites were contaminated and unfit for potable use in thearea.

Published: October 2023

Aquifer geohydraulic properties in Jesse were studied by the application of vertical electrical sounding (VES) and pumping test. The VES data was collected using ABEM SAS 1000 Terrameter and results processed using manual matching of curves and computer iteration, and interpreted in the forms of geologic models and geoelectric layers. The aquiferous unit was found at a depth of 5.30 m to 30.30 m with a range of resistivity from 87.30 Ω-m to 1945.40 Ω-m. Dar-Zarrouk parameters estimation and results of borehole pumping test produced the aquifer hydraulic parameters. The hydraulic conductivity values range from8.171 - 8.279 m/day, transmissivity from 43.8770 - 517.7480 m2/day, and formation factor from 0.369 - 8.501. These results are indications of a prolific and high yielding aquifer capable of withstanding long duration of pumping. Results of groundwater electrical conductivity and total dissolved solids ranged from 11.65 - 198.80 μs/cm, and 29.40 - 35.40 mg/dm3 respectively, signifying very moderate mineralization of the groundwater. The average electrical conductivity of 68.04 μS /cm and total dissolved solids of 32.58 mg/L were lesser than the acceptable limits of the Nigerian Standard for Drinking Water Quality (NSDWQ) of 1000 μS/cm and 500 mg/L respectively. This study affirmed that the aquifer in Jesse is suitable for groundwater exploitation for local and regional purposes.

Published: October 2023

Auxiliary variables correlated with the study variables have been identified to be useful in improving the efficiency of ratio, product and regression estimators both at planning and estimation stages. The existing regression-based estimators are functions of auxiliary variables which are sensitive to outliers. In this paper, a modified class of estimators is proposed using robust non-conventional measures of dispersion which are robust against outliers or extreme values. The properties (Biases and Mean Squared Errors (MSEs)) of the modified class of estimator were derived up to the first order of approximation using Taylor series approach. The empirical studies were conducted using stimulation to investigate the efficiency of the proposed estimators over the efficiency of the existing estimators. The results revealed that the proposed estimators have minimum MSEs and higher Percentage Relative Efficiencies (PREs) among all the competing estimators. These results implied that the proposed estimators are more efficient and can produce better estimate of the population mean compared to other existing estimators considered in the study. Therefore, it can be concluded that proposed estimators have better predictive power for estimating population mean when the study (interest) variables are characterized with outliers or extreme values.

Published: October 2023

Geological mapping and petrographic studies of rocks provide useful information on texture and mineralogical composition of rocks which can be used in the exploration and exploitation of any associated mineralization. However, few regional studies have been conducted in Minna and environs. Here, preliminary field mapping and petrography of out crops in Saigbe environ were conducted to determine their identification, structural and mineralogical composition. Twenty-one rock samples were collected, eight of which were used for thin section analysis. Joint directions were measured and plotted on rose diagram. Results show that Saigbe is underlain by schist, amphibolite and granite with minor pegmatite intrusions. Joints, faults, fold and foliations constitute main structures. Joints in the schists trend NE-SW, while those in the granites trend NW-SE, suggesting different episodes of emplacement for both rocks. Petrography revealed that the schists comprised quartz, biotite, muscovite, plagioclase and opaque mineral, while the amphibolites are composed largely of quartz, hornblende, plagioclase feldspar and opaque minerals. The granites are composed of quartz, microcline, plagioclase feldspar, muscovite and opaque minerals. The pegmatite dykes in the granites comprised quartz, plagioclase feldspar, orthoclase feldspar, muscovite and gemstones, hence interpreted as product of residual melt. The pegmatites make interesting target for mineral exploration.

Published: October 2023

Aedes aegypti mosquitoes are the main vector of human arbovirosis in tropical and subtropical areas. Their adaptation to urban and rural environments generates infestations inside households. Therefore, entomological surveillance associated with spatio-temporal analysis is an innovative approach for vector control and dengue management. Here, our main aim was to inspect immature pupal stages in households belonging to municipalities at high risk of dengue in Cauca, Colombia, by implementing entomological indices and relating how they influence adult mosquitos’ density. We provide novel data for the geographical distribution of 3,806 immature pupal stages of Ae. aegypti. We also report entomological indices and spatial characterization. Our results suggest that, for Ae. aegypti species, pupal productivity generates high densities of adult mosquitos in neighbouring households, evidencing seasonal behaviour. Our dataset is essential as it provides an innovative strategy for mitigating vector-borne diseases using vector spatial patterns. It also delineates the association between these vector spatial patterns, entomological indicators, and breeding sites in high-risk neighbourhoods.

Published: October 2023

This study revealed the health risk associated with selected heavy metals (Mn, Cu, Zn, Cr, Co, Pb, Ni and Cd) in Okene Metropolis. Soil samples from workshops and other anthropogenic activities were collected and their heavy metal contents analyzed. The two pathways of exposure to heavy metals in soils are: ingestion and by dermal contact pathways. Children are the most susceptible part of the population and highly venerable to health risk Health risk assessment showed that the order of exposure was children > adults. This research revealed the health risk assessment for children and adults are less than 1 and therefore, heavy metals were not accessible to any health risks. Despite the lack of health risk at present, continuous activities from these workshops and other anthropogenic activities may likely lead to soil pollution in future. Therefore, it is recommended that there should be continuous monitoring of heavy metals in Okene Metropolis to ascertain the health risk associated with heavy metals.
COMPUTATIONAL MODELLING OF THE ACTIVATION PARAMETERS OF DIELS ALDER REACTION OF QUINOFLAVONOID AND 2, 3 DIMETHYLBUTA-1, 3-DIENE
Authors: Adeboye O. O.
Published: October 2023

Kinetics and thermodynamics of Diels alder reaction of quinoflavoniod and 2, 3 dimethylbuta-1,3-diene was studied using ab-initio method with Hartree Fock at 6-311G* basis set in spartan, Conformational search was carried out on the molecules to obtain the structures that has the lowest energy, an indication of the stability of the structure. Reaction path calculation was done on the most stable structure using C26 – C15 and C27 – C14 as reaction coordinate in 20 iterations, this was done to ascertain the reaction mechanism. Geometric calculation was carried out on the structures of the reactant, transition state and products to obtain the bond length, bond angle, dihedral angle and atomic charge distributions. Kinetics and thermodynamic parameters was calculated at 3480C. The reaction proceeded through a concerted asynchronous six-membered cyclic transition state. True saddle point was characterized and verified by the presence of only one imaginary vibrational frequency which smoothly connect the reactant, the transition state and the product. Negative values obtained for ?H* (-66.65kJ/mol shows that the reaction is exothermic and according to literature this may be as a result of conversion of two of the ?-bonds to two new ?-bonds). Values obtained for energy of formation (-1329.974 hatrees, -1329.911 hatrees, and 1330.023 hatrees for GS, TS and PRD respectively) according to Hammond’s postulate, confirms the exothermicity of the reaction. ?Greaction (-60.16kJ/mol, shows that the reaction is favourable, Negative ?S* (-11.29J/mol.K) suggests the spontaneity of the reaction and Ea (-63.76kJ/mol) suggests that the reaction involves transfer of electrons. It was also observed that rate constants decrease with increase in temperature, although very uncommon but suggested a complex reaction mechanism.

Published: October 2023

Separation of Ni(II) and Cr(VI) from a solution containing a mixture of both ions was conducted using adsorption technique with Duolite A7 resin as the adsorbent. The effects of ionic strength (1.0 - 5.0 M), resin dosage (1.0 - 5.0 g), temperature (30 - 50°C) and equilibration time (5 - 150 mins) on the separation of both ions were investigated. Up to 91% adsorption of Ni(II) by the resin was observed at pH 4.5. It was observed that Ni(II) ion under each of the conditions showed significantly higher binding affinity to the resin than Cr(VI). Adsorption of Ni(II) was rapid and was completed in about 10 min equilibration time. There was a continuous decrease in the adsorption of both ions as the temperature of the mixture increased. The FTIR spectra of the unloaded and loaded resinshowed that Duolite A7 is highly selective for the optimum recovery of Ni(II) from a solution containing a mixture of Ni(II) and Cr(VI) ions under the considered experimental conditions.

Economic Efficiency of Public Administration in the Field of Digital Development
Authors: Ortina Ganna
Published: October 2023

"In the article, based on the analysis of the essential characteristics of digitalization, it is proposed to consider the concept of efficiency in relation to the activities of public authorities as a generalized and interconnected series of such concepts as economy, qualimetricity, and effectiveness. The efficiency of public administration, including economic efficiency, is considered as the implementation of management, during which the set goals are achieved (solving a certain socially significant problem, satisfying the interests of the population, maintaining digital competitiveness of region and country) while minimizing costs and observing the current standards of digital maturity. It is proposed to understand the assessment of the effectiveness of public administration as a set of methods for measuring actual indicators that reflect the results of the public authorities’ activities within the framework of the strategies, programs, and projects being implemented in accordance with the criteria laid down in them, and in this case the assessment is seen as the direct result of such a measurement, which serves to compare the activities of public administration subjects, compare this activity with the declared goals, the results of past periods. The proposed leading and signal indicators can be used in planning and forecasting the level of digital development of regional socio-economic systems."

"Digitalization is no longer an integral part of social relations at the stage of their development. It covers almost all areas of everyday life, and it is now impossible to do without it in some cases. Public finances are no exception since they are also undergoing significant changes in the new realities. The development of information technologies makes it possible to administer many processes in the field of public finance faster and more efficiently, including control over the accumulation and expenditure of funds. The academic paper defines the modern architecture of information systems used in the field of public finance; their general advantages are analyzed, such as: efficiency (speed), data compatibility, cost-effectiveness, convenience, transparency, consistency, reliability, and elimination of duplication. The architecture of information systems and technologies in the field of public finance in the EU and Ukraine is considered. The purpose of the academic paper is to define the structure of applying information technologies to modernize public and municipal financial management. The bibliographical research, both descriptive and analytical, was the main research method. The conclusion has been made in the present scientific work that there is a need for further digitalization of the above-mentioned sphere in Ukraine. In particular, it is proposed to develop the concept of e-government by fully digitalizing society, ensuring transparency and openness, reporting to citizens for public funds, and implementing feedback from them. At the same time, it is necessary to continue involving citizens in public finance management through feedback, voting and platform solutions. The development of national public finance management systems based on adopting the EU standards through applying information technologies represents a potential area for further studies."

Erzurum Eyaletinde 1742-1800 Yılları Arasında Güvenlik Sorunları
Authors: KOÇYİĞİT Mehmet
Published: October 2023

Osmanlı İmparatorluğunun yükselişinin sona erdiği yıllarda toplumsal sorunlar giderek artmaktaydı. Toplumda oluşan kargaşa hali suç oranlarının da artmasına sebep olmuştur. Günlük hayatta karşılaşılan birçok sorunun ana kaynağını da güvenlik zafiyeti teşkil etmiştir. Eşkıya denilen zümre taşrada yaşayan halkın parasını ve değerli eşyalarını gasp etmiştir. Mala ve toprağa haksız müdahalelerde artışlar yaşanmıştır. Halkın değerli eşyaları veya hayvanları çalınmıştır. Devlet ise suçlara karşı caydırıcı önlemler almaya çalışsa da suçların artış oranını engelleyememiştir. Bu çalışmada 1742-1800 yılları arasında 1, 3, 5, 7 ve 9 numaralı Erzurum Ahkâm Defterlerine yansıyan güvenlik ile ilgili şikâyetlerin nasıl ve ne şekilde yapıldığı, şikayetlere verilen çözüm önerileri incelenmiştir. Bu nedenle belirtilen yıl aralığına ait hükümler taranarak güvenlik ile ilgili hükümler seçilmiştir. Tespit edilen hükümlerde daha çok cinayet, ırza tasallut, hırsızlık, iftira ve eşkıyalık gibi konularda şikâyetlerin yoğunlaştığı görülmüştür.

Kur an da İç İletişim
Authors: SADAN Hamza
Published: October 2023

“Kur’an’da iç iletişim” ismini taşıyan bu çalışma iki ana kavram üzere tesis edilmiştir. Bunlardan birincisi Allah Teâlâ’nın sözlerini içeren “Kur’an” diğeri ise yine Allah Teâlâ’nın insana yerleştirdiği “iç iletişim”dir. İç iletişim genel iletişimin içerisinde incelenen bir konu olarak insanın içyapısına, benliğine ve kendisine dair algısına dayanır. Kişinin kendisiyle iletişimi kişinin kişiler arası iletişimi hatta bütün hal ve hareketlerinin altında yatan temel yapıyı oluşturmaktadır. Kur’an doğru düşünüş (inanç) ve doğru davranışı gerçekleştirmeyi hedefleyen ilahi bir metindir ve iç iletişimin doğru ve yanlış kurgulanmasıyla ilgili birçok örnek mevcuttur. Dolayısıyla bu çalışma iç iletişimle ilgili Kur’an’dan birtakım referanslar ve örnekler bulabilmeyi; bu şekilde kişinin kendisiyle iletişimi sahasında alana katkı sunmayı amaçlamaktadır. Normatif bir metin, iyi ve doğrunun ilahi kaynaklı yegâne belirleyicisi olarak Kur’an’dan iç iletişimle ilgili ipuçlarının belirlenmesi önem arz etmektedir. Bu bağlamda kişinin içyapısıyla ilgili olan nefs kavramı ve iç iletişimle ilişkilendirilebilecek olumlu ve olumsuz örnekler üzerinde durulmuştur. Bu örnekler aynı nesnel bir durumun nasıl farklı davranışlara götürdüğünü ortaya koymaktadır.

Harid Fedai nin Kıbrıs Gazetesi nde Yayımlanmış Eski Basınımızdan Başlıklı Köşe Yazıları
Authors: ÖZAŞIK Orkun
Published: October 2023

Kıbrıslı Türkolog Harid Fedai, Kıbrıs Türk basını hakkında birçok çalışmaya imza atmıştır. Bunlardan en uzun soluklu olanı 11 Temmuz 1989 – 19 Haziran 2017 tarihleri süresince Kıbrıs gazetesinde “Eski Basınımızdan” başlığı altında yazdığı köşe yazılarıdır. Bu köşe yazılarında Kıbrıs’ta basılmış eski harfli gazete ve dergilerden aktarımlar yapmıştır. Siyasi, sosyal, kültürel birçok anekdota ve önemli bilgiye haiz bu gazetelerden yapılan alıntılar, toplu olarak ele alındığında önemli bir külliyatın ortaya çıktığı görülmektedir. Bu külliyat; tarih, halkbilim ve siyasal bilimler alanlarında Kıbrıs hakkında yapılacak çalışmalar için önem arz etmektedir. Bu nedenle köşe yazılarının hangi gazeteleri ve hangi sayıları içerdiği hakkında bilgi vermek amacıyla köşe yazılarının yayınlandığı Kıbrıs gazetesinin 1989’dan 2017’ye kadarki sayıları taranarak listeleme ve derleme yapılmıştır. Aynı zamanda Harid Fedai’nin Ahmet An ile birlikte kaleme aldığı Örnekleriyle Kıbrıs Türk Basını Tarihi I kitabına da başvurarak bu gazetelerin nüshalarına dair çıkarımlarda bulunulmaya çalışılmıştır.

Antik Yunan Tıp Geleneği ve Farmakolojisinin Galenos Sonrası Alımlanması
Authors: Yalazı Esra
Published: October 2023

MÖ 5. yüzyılda Hippokrates ve ardılları ile başlayıp MS 2.-3. yüzyıllara değin özellikle Dioskorides ve Galenos ile devam eden Antik Yunan tıbbı ve buna dayalı olarak gelişen farmakoloji geleneği (materia medica), antik dönemden miras kalan yazılı tıbbi kaynakların önemli bir kısmını oluşturmaktadır. İkinci bir süreç çerçevesinde ise, bu yazılı kaynaklar karşılıklı fetih hareketleri sonucunda İslam medeniyeti sayesinde İskenderiye Kütüphanesi üzerinden Yunanca’dan Arapça’ya, ardından Hristiyan medeniyeti sayesinde Toledo kütüphaneleri üzerinden Arapça’dan Latince’ye ve Hümanist hareket sayesinde de İstanbul’un fethi sonrası götürülen nüshalar üzerinden doğrudan Yunanca’dan Latince’ye çevrilmiştir. Bu çeviri hareketleri aynı eserlerin farklı zaman ve toplumlarda onların ihtiyaçları çerçevesinde yeniden çevrilmesine ve alımlanmasına yol açmıştır. Temelde filolojik bir çaba olan bu çeviri hareketleri aynı metinlerin, kültürel, felsefi ve dini motiflerle farklı tıp ekolleri sayesinde yeniden yorumlanmasını ve böylece tıp biliminin ve ona eşlik eden farmakoloji bilgisinin gelişmesini sağlamıştır. Ancak kültürel duruşlar yüzünden her ekolün Hippokrates’e yeni bir imge çizdiği görülmektedir. Bu imgelerin çeşitliliği tarihsel sürecinin incelenmesini gerekli kılmaktadır. Bu çalışmada Nietsche'nin gerçek tarih kavramına dayalı Foucault’nun soy kütüğü yöntemi ile bu sürecin incelenmesine çalışılmıştır. Bu sayede bir farmakoloji tarihi kadar, kültürler arası etkileşimin filolojik yönüyle bir medeniyet tarihi ortaya konabileceğinin gösterilmesi amaçlanmıştır.

Diseño de hormigón hidráulico con biocarbon
Authors: Suárez Andrés Sebastián Zalamea , Sanchez Luis Mario Almache , Vera Manuel Salvador Alvarez
Published: October 2023

El biocarbono es una alternativa ambiental viable para mitigar la contaminación de la biomasa residual. Esta investigación busca reducir el impacto ambiental de materiales como cemento, mortero y hormigones hidráulicos al encapsular carbono estable en biocarbón. Se evaluó la aplicabilidad del biocarbón producido en nuestra región y su incorporación en hormigones hidráulicos, sin afectar su rendimiento. Se realizó una revisión bibliográfica de investigaciones similares para obtener información sobre las dosificaciones de materiales utilizados en experimentos similares y los factores que intervienen en el proceso. Se diseñó una mezcla base de hormigón y se agregó biocarbón en diferentes proporciones. Se fabricaron probetas de hormigón y se sometieron a pruebas de carga axial. Se utilizó biocarbón en porcentajes de 1,5%, 3,0%, 4,5% y 25,0%; lo que resultó en aumentos de resistencia a la compresión del hormigón a los 28 días de 19%, 15%, 14% y -77%, respectivamente, en comparación con el hormigón de control sin biocarbón. Se concluye que el uso de biocarbón aumenta la resistencia a la compresión del hormigón en diferentes dosificaciones. Se sugiere investigar el comportamiento del hormigón con dosificaciones de biocarbón entre 0,1% y 2,0% del peso del cemento, para optimizar sus características. También se debe estudiar las propiedades y beneficios adicionales de estos hormigones. La viabilidad comercial del biocarbón en compuestos de cemento depende de factores como la disponibilidad y el tipo de materia prima, y la escala de producción. Algunas investigaciones indican que el hormigón con biocarbón añadido puede generar beneficios económicos netos positivos.
SKL-21 Tipi Gergi Kıskaçlarının Deneysel Hasar Analizi
Authors: MOTAMENİ Ali , FARUKOĞLU Ömer Can , GÜRBÜZ Rıza
Published: October 2023

Bu araştırmanın amacı demiryolu hatlarında kullanılan bağlantı elemanlarından biri olan SKL-21 gergi kıskaçlarının hasar analizinin deneysel olarak tespitidir. Çalışmada kullanılan kıskaçlar aynı şehir içi metro hattından 4 adetlik bir örneklemdir. Kıskaçların kırılma sebeplerini anlamak için numuneler üzerinden çeşitli ölçümler alınmıştır. Kıskaçlar öncelikle gözle muayene edilmiş ve daha sonra taramalı elektron mikroskobu (SEM) ile incelemeye alınmıştır. Mikroyapı incelemeleri ve enerji dağılım spektroskopisi (EDS) analizleri yapılmıştır. Ayrıca numunelerden Vickers sertlik ölçümleri alınmıştır. Yapılan hasar analizi kapsamında, kırılmanın oluşumunda iki farklı mekanizma görülmüştür. İlk duruma göre kıskaçlar hatalı montajdan dolayı ray tabanına göre normalden daha düşük bir pozisyonda kalmıştır. Bu durum; tren ray üzerinden geçerken aşırı deplasmana sebep olmakta ve tren rayın üzerinden geçerken kıskaçların zarar görmesi ile sonuçlanmaktadır. İkinci durum ise bazı bağlantı noktalarında kırılan kıskaçların karşısındaki kıskaçların yeterli torkla monte edilmemesidir; bu da kıskaçların aşırı yüklenerek kırılmasına neden olur.
