From the Persianate World to Multiple Worlds of the Persianate
Authors: Arslan C. Ceyhun 
Published: November 2024

ABSTRACT
This article fleshes out two future directions for Middle Eastern studies as it puts the recent scholarship in Ottoman studies in dialogue with Alexander Jabbari’s The Making of Persianate Modernity. First, like Jabbari, who interpreted the sexual puritanism in modern Persian literary histories as a convention of Persianate modernity, the author notes that critics can analyze key claims in texts of Arabic and Turkish modernity as generic conventions rather than as facts that capture sociopolitical transformations of modernity. Second, the author argues that The Making of Persianate Modernity, which examines the “form that the Persianate takes” in modern Iran and South Asia, can serve as a point of departure for studying the diverse forms that the Persianate takes in other Middle Eastern contexts, which do not have to be subsumed to a single Persianate world. While the term “Persianate world” has served as a useful heuristic concept, critics can shift their focus to “the multiple worlds that the Persianate has taken” as they analyze communities, such as the Ottoman literati, who do not self-identify as members of a cosmopolitan Persianate community. The Persian textual heritage can cultivate multiple worlds that uphold different, and even contradictory, political ideals and aesthetic norms.
Numerical analysis of soil reinforced by sand columns using different installation methods
Authors: Laouche Mohamed , Bezih Kamel , Djenane Mohamed , Karech Toufik 
Published: November 2024

This study involves a finite element numerical simulation of laboratory tests conducted on small-scale models. The tests involved the installation of columns using different techniques: without soil displacement and without column compaction (WR-NC), and without soil displacement but with column compaction (WR-WC). The reinforced soil masses were then subjected to a uniform 150 kPa load. A comparison between the numerical and experimental results showed excellent agreement, validating the simulation. Following this validation, a parametric analysis was carried out to examine the effects of the various parameters on the behavior of the reinforced soil masses. In the first method, three different column diameters were analyzed, focusing on the effects of diameter (area replacement ratio), column length, and geogrid containment benefits. In the second method, three levels of compaction pressure were applied during the column installation. The study evaluated the impact of column installation techniques on the behavior of the reinforced masses. The findings indicate that settlement reduction is proportional to the increase in area replacement ratio and column length. Additionally, confining the columns with geogrid was shown to be effective in further reducing settlements. The results also revealed that increasing compaction stress leads to greater radial expansion of the columns, which densifies and stiffens the surrounding soil, thereby reducing settlement. Overall, the study concludes that column installation techniques significantly influence the behavior of reinforced soil masses.

This study aims to determine the potential for using activated carbon prepared by local agricultural waste for the treatment of wastewater loaded with organic pollutants. The activated carbon was prepared by chemical activation using phosphoric acid H3PO4 at an “85%” concentration, from local date kernels TEMJOUHERT (TMG) from the Ghardaïa region, Algeria. The activated carbon synthesis yield is equal to 28.56%. The adsorbent prepared was characterized by determining its physical and chemical characteristics, in particular the bulk density, the ash content, the iodine number, the surface functions by the Boehm method and the pH at the point of zero charge. Thus the textural properties are determined by scanning electron microscopy SEM and the Burnauer-emmett-Teller (BET). The surface area and micropore volumes of activated carbon TMG; were found to be 639.9190 m2/g and 0.420779 cm3/g respectively. All the results obtained from the treatment of wastewater from the Atteuf "kef doukhane area in the Ghardaia region. are clear that: the best pollutant removal rates are 84.75% for PO3-4; 85.21% for COD and 74.55% for NH4+ by activated carbons; using a mass of 1g of adsorbent per 100 ml of water, 90 min contact time and 250rpm stirring speed.

Published: November 2024

A partir da década de 1980, foram desenvolvidas pesquisas sobre a relação entre os reservatórios hídricos e a climatologia local. Este trabalho objetiva avaliar se a sazonalidade das chuvas no entorno do Reservatório Chapéu D’Uvas (MG) sofreu modificações ao longo do tempo. Foram usados dados de pluviosidade diária do posto pluviométrico Chapéu D’Uvas para o período de 1950-2021. A técnica das pêntadas foi aplicada para a identificação do (a) início e do final do período chuvoso; (b) a quantidade de pêntadas secas no ano e, (c) a quantidade de pêntadas secas durante a estação seca. Técnicas estatísticas – estatística descritiva, equação de regressão e os testes de Mann-Kendall e de Pettit - foram aplicados a essas séries temporais. A análise das pêntadas revelou que ao longo da série há um atraso em uma pêntada para o início da estação chuvosa e a antecipação em duas pêntadas para o final da estação, prolongando-se assim, o período da estação seca em três pêntadas (15 dias). O teste de Pettit revelou ainda que a tendência de ampliação da estação seca mostrou-se mais significativa a partir do ano de 2006. Sendo assim, as alterações observadas na sazonalidade das chuvas no entorno do reservatório, ampliando a estação seca e reduzindo o período chuvoso, podem indicar aos gestores dos recursos hídricos atenção quanto a questão da segurança hídrica local e regional.

Introdução: A síndrome de Sjogren (SS) é uma doença sistêmica e crônica, de caráter autoimune, em que ocorre o acometimento de glândulas salivares e lacrimais, que resultam em xerostomia e xeroftalmia, além de sintomas extraglandulares, como fadiga, dor musculoesquelética, afecções pulmonares, renais, hepáticas e neurológicas. Devido a ampla gama de manifestações clínicas, a avaliação médica desses pacientes torna-se desafiadora. Objetivo: Elucidar os aspectos fisiopatológicos, clínicos, diagnósticos e terapêuticos da Síndrome de Sjogren. Metodologia: Trata-se de uma Revisão Integrativa de literatura, que utilizou as bases de dados MEDLINE/PubMed, SciELO, LILACS e Cochrane Library, desenvolvida em seis etapas, objetivando responder a pergunta norteadora desenvolvida pela estratégia PICO. Resultados e Discussão: A SS é uma doença multifatorial, com alguns polimorfismos reconhecidos (HLA -DR e TNF-a), porém a patogênese específica ainda não está totalmente elucidada. 90% dos pacientes apresentam xerostomia e 95% xeroftalmia. A artrite e artralgia estão entre as manifestações extraglandulares mais comuns da SS. O diagnóstico envolve o quadro clínico, evolução e a detecção de determinados anticorpos, após a exclusão de diagnósticos diferenciais. O tratamento é principalmente sintomático, com objetivo de melhorar a qualidade de vida do paciente. Conclusão: A SS apresenta ampla variedade de manifestações clínicas, com morbidade significativa. É necessário uma abordagem abrangente para que o diagnóstico preciso e adequado seja realizado. A SS ainda carece de consenso acerca dos critérios de classificação e de aspectos terapêuticos, que estão em evolução constante, evidenciando a necessidade de pesquisas futuras.
Impact of image-guided surgical techniques in complex bone reconstruction for maxillofacial fractures
Authors: Flores Gutierrez Daniel Alejandro , Fernandez Hidalgo  Jorge Erick , Cuzco Ramírez Yadira Alexandra , Ganchozo Peralta Daniela Beatriz 
Published: November 2024

Maxillofacial fractures present complex surgical challenges that require precise reconstruction techniques. Image-guided surgical methods, including computer navigation and 3D imaging, are increasingly used to improve surgical outcomes, yet selecting the optimal modality remains difficult due to the varying benefits of each technology. The databases used in the current research include, but are not limited to, PubMed, Scopus, and Google Scholar for article searches. Controlling for sources of bias, the review selected publications on image-guided surgical approaches to managing craniofacial fractures. Studies were identified based on the following criteria: methodology, relevance and patient-oriented results. Thus, analytical categories were developed to evaluate the results, including surgical meticulousness, complication incidences healing, and overall patient satisfaction. The research shows that the availability of enhanced imaging tools and navigation, including CT-nav, 3D-image ster, and intra-operative CBCT, enhances surgical precision and diagnostic accuracy. Preoperative planning repeatability when using CAN was up to 86.5%, and the need for revisions in maxillofacial trauma patients was reduced. Research on computation mirroring for navigation found differences between 0.12 mm, revealing enhanced surgery accuracy. Evaluations of image-guided techniques indicate their advantage over other methods in maxillofacial fracture operations in terms of accuracy and efficiency. Even nowadays, they provide significant improvements in patients’ treatment and surgical precision despite certain shortcomings in terms of technology and availability. Further studies need to consider enhancements to the navigation systems and consider cost benefits, depending on the type of setting in which the patient is located.

Study’s Excerpt

Radon gas contamination across diverse drinking water sources within Makurdi, Nigeria, was investigated.
The RAD-7 detector was used, and the results revealed elevated radon levels exceeding WHO limits in some specific locations.
There is a need for targeted risk mitigation strategies and continuous monitoring of Radon gas contamination in the area.

Full Abstract
Concern over radon gas's potential health risks when used or ingested in homes is growing, as is the issue with its presence in sources of drinking water. In this study, water samples were collected from various locations in Makurdi, Benue State, Nigeria, and the amount of radon gas present was measured using the Radon Detector (RAD-7). The study used a methodical sampling strategy to gather water samples from wells, boreholes, and surface water bodies throughout various Makurdi locations. The gathered water samples were examined using the RAD-7 detector, a trustworthy and sensitive device for measuring radon gas. The radon levels ranged from trace levels (20.0 ) to higher quantities (122.0 ), raising worries about potential health implications for nearby people reliant on these water sources. Thirty (30) samples of water were gathered for this investigation. The samples' radon content ranged from 10.3 to 122.0 Bq L-1, which is within the World Health Organization's (WHO) allowable limit and other regulatory bodies (100 Bq L-1) except in the sample collected from Court 5 and Logo1, which was higher than the set limit. The results of the analysis demonstrated that there were large variations within the range of 0.61 0.39-11.80 1.85 and a mean of 57.36 in the amounts of radon gas in the water samples obtained from the different sources. More research and monitoring are advised to gain a complete understanding of radon distribution and to develop workable radon risk reduction plans for water sources.

This research presents the use of antimicrobial peptides derived from Pisum sativum (pea) seeds as natural preservatives for extending the shelf life of local African beverages.
It demonstrated that peptides, particularly from germinated peas on day four, exhibits strong antimicrobial activity against bacteria.
Plant-derived peptides could replace synthetic preservatives in the food and beverage industry.

Full Abstract
The demand for natural and effective food preservatives has increased due to the growing concern over the safety and quality of processed beverages. Antimicrobial peptides have gained significant attention as natural alternatives to synthetic preservatives, offering potential benefits such as broad-spectrum activity and lower toxicity. Germinating seeds of Pisum sativum were harvested on days 2, 4, 6 and 8 and peptides were extracted and purified using Ammonium Sulphate Precipitation at 70% saturation, Dialysis, Gel filtration and the peaks were obtained. The molecular weight of peptides was determined using SDS-PAGE while Six (6) Bacteria and Four (4) Fungal species were isolated and characterized using standard procedures. The highest protein concentration was obtained with germinated peas day four (P4) with a value of 1.7866mg/mL, while the highest zone diameter of inhibition was recorded with peptide of germinated pea seeds day six fraction three (P6:3) with a value of 17.000±0.577mm against B. cereus. The least MIC value, expressed in protein concentration (mg/mL), was obtained as 0.0253mg/mL with 100% concentration of the peptide of germinated peas on day four (P4). All four (4) fungal species recorded no activity/zone diameter of inhibition. Sanitizing activity of the peptides on the ‘Zobo’ drink adjusted to pH 2.3, at 0hr, 24hr, 48hr and 72hrs was carried out, and all the purified peptides extended the shelf life of the drink except for peptide of germinated peas on day two. Sensory evaluation equally indicated that the drink was preserved with 10% (P4:4) at pH 2.3, being the most preferred treatment by the judges with a percentage likeness of 72.22% after 72hrs of storage. Findings from this study highlight the potential of these peptides in developing innovative and safe preservation techniques for extending the shelf life of local African beverages. This study further offers promising insights into the application of Pisum sativum peptides in preserving traditional drinks like 'Zobo.'

Study’s Excerpt

The lithological and structural composition of the Ikara North-Central Basement Complex in Nigeria is investigated.
Detailed field and petrographic analyses were carried out to identify the rock types of the area.
The geological map of the area is updated.

Full Abstract
The lithological and structural architecture to unravel the compositions and tectonic evolution of the Nigerian Basement Complex has not been fully documented by geoscientists. As such, this research aimed to investigate the lithological and structural characteristics of the Ikara North-Central Basement Complex. Detailed petrographic and field analysis reveals the prevalence of gneiss and granite lithologies characterized by significant structural features such as fractures, folds, and foliations. These findings offer new understandings of the tectonic evolution of the region. The study area mapped is the Ikara Sheet 103 Federal Survey Topographic Sheet to a scale of 1:100,000. The major lithological units underlying the study area are gneisses and granites. However, these major rock types have varieties, namely migmatitic gneiss, granite gneiss, migmatitic (augen) gneiss, porphyroblastic gneiss, medium to coarse-grained granites, and porphyritic granites. These rock types were intruded by quartzites, pegmatitic dykes, quartz, and aplite veins. Rock samples were observed and studied based on their mineralogical composition, color, and texture. The results of the petrographic analysis showed that the rocks are mainly composed of quartz, plagioclase feldspars, alkali feldspars, mica (biotite and muscovite), hornblende, garnet, and accessory minerals like zircon and magnetite. Geological structures were also observed during the field study, namely fractures (joints and fractures), foliations, lineations, veins, dykes, and various landforms. Photomicrographs from thin section analyses revealed micro-structures like myrmekites, micro-folds, and micro-fractures were also observed. Mineralization such as amethyst and cassiterite were hosted by quartz veins and pegmatites in porphyritic granites, respectively. A litho-structural map was produced, exhibiting the lithological units and regional structures cross-cutting the area of research.
