Published: August 2023

The development of high-temperature organic adhesive for bonding ultra-high-temperature ceramics with excellent thermal shock resistance has important significance to thermal protection systems for high-temperature environment application. In this study, high-temperature organic adhesive (HTOA) with carbon-fiber-SiC nanowires (CF-SiCNWs) binary phase enhancement structure was prepared. The method is that the SiCNWs grow on the chopped carbon-fiber surface and in the matrix of modified HTOA during high-temperature heat treatment with the help of a catalyst by a tip-growth way and with a vapor–liquid–solid (V-L-S) growth pattern. The results showed that the CF-SiCNWs binary phase enhancement structure plays a significant role in improving thermal shock resistance of high-temperature organic adhesive. The retention rate of the joint bond strength for the bonding samples after 20 cycles of thermal shock testing reaches 39.19%, which is higher than for the ones without CF, whose retain rate is only 6.78%. The shear strength of the samples with the CF-SiCNWs binary phase enhancement structure was about 10% higher than for those without the enhancement structure after 20 cycles of thermal shock.

Published: August 2023

Research on rare-earth fluorides is of urgent and critical importance for the preparation and emerging applications of high-purity alloys. The fluorination of Sc2O3 by NH4HF2 to fabricate ScF3 is investigated. The effects of the fluorination temperature, time and mass ratio of reactant on the fluorination rate and fluoride are discussed in this work. The fluorination reaction was first confirmed using thermodynamic calculation. The thermal and mass stability of the fluorination process were analyzed by thermogravimetric and differential scanning calorimetric (TG-DSC). The as-obtained products at different fluorination temperatures were characterized by Powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM). The results indicated that the fluorination began at room temperature (RT) with the formation of (NH4)3ScF6. With the increase of temperature, the reaction proceeded sequentially through the formation of NH4ScF4, (NH4)2Sc3F11, and finally ScF3. The fluorination rate increased with the increase of fluorination temperature and holding time. ScF3 with a purity of 99.997 wt.% could be obtained by fluorination at 400 °C for 2 h.

Published: August 2023

The Si atom diffusion behavior in Ni-based superalloys was evaluated based on first-principles calculations. Also, the site occupation of Si atoms as the melting point depressant elements in Cr, Mo, and W atom doped γ-Ni and γ′-Ni3Fe supercells was discussed and Si atom diffusion behaviors between both adjacent octahedral interstices were analyzed. Calculation results indicated that formation enthalpy (∆Hf) was decreased, stability was improved by doping alloying elements Cr, Mo, and W in γ-Ni and γ′-Ni3Fe supercells, Si atoms were more inclined to occupy octahedral interstices and the diffusion energy barrier was increased by increasing the radius of the doped alloy element. Especially, two diffusion paths were available for Si atoms in the γ′-Ni3Fe and Si diffusion energy barrier around the shared Fe atoms between adjacent octahedral interstices and was significantly lower than that around the shared Ni atoms. The increase of interaction strength between the doped M atom/octahedron constituent atom and Si atom increased Si atom diffusion and decreased the diffusion energy barrier. The Si atom diffusion behavior provides a theoretical basis for the phase structure evolution in wide-gap brazed joints.

Some reports in the literature show the advantages of fluoride-containing apatite ceramics over hydroxyapatite (HAP), at least in some aspects. While HAP has been used extensively in the treatment of bone defects, fluoridated apatite has hardly been tested in vivo. In order to verify the biological properties of fluoride-doped apatite and to assess its therapeutic potential, we synthesized fluorapatite (FAP) and applied it as a filling in bone defects of experimental animals (rabbits). The treatment effects were evaluated on extracted bones after 3 and 6 months from implantation using peripheral quantitative computed tomography (pQCT), dual-energy X-ray absorptiometry (DXA), radiography (X-ray) and histological staining. The study proved the integration between FAP and the bone tissue, thus indicating its stimulating effect on new bone formation and mineralization. The results achieved after 3 months of treatment were difficult to interpret unequivocally and suggested the transient delay in FAP integration of bone in comparison with HAP. The reasons for this phenomenon are unclear. Most likely, these differences between FAP and HAP resulted mainly from the different porosities, densities and ionic reactivity of the ceramics, which in our opinion affected their solubility, integration and degree of bone tissue resorption. However, it was shown that 6 months after implantation, similar level of bone defect regeneration was achieved for both FAP and HAP. In this article, we present our hypothesis concerning the basis of this phenomenon.
HPV Opportunistic Vaccination: A Literature Review and a Single-Center Experience in Northern Italy through the COVID-19 Pandemic

Published: August 2023

The World Health Organization (WHO) set the goal of 90% HPV vaccination coverage in the population to eliminate cervical cancer. Opportunistic vaccination is performed outside the free vaccination or catch-up programs. Both free and opportunistic HPV vaccination programs experienced slowdowns during the COVID-19 pandemic. In this retrospective study, we aimed to identify the benefits and the obstacles of opportunistic vaccination among male and female individuals who took advantage of the “on-demand” service offered by San Raffaele Hospital in Milan from April 2018 to May 2023. The impact that the COVID-19 pandemic had on vaccination adherence was also analyzed. Data on a total of 527 subjects were collected from an in-house database and through personal interviews. Women in the cohort of older patients (over 25) adhered to the vaccination schedule more than younger women. Opportunistic vaccination request is influenced by the need of a gynecologist, a general practitioner, or public health clinic availability. Women also showed good adherence to screening, demonstrating awareness of the importance of cervical cancer secondary prevention despite vaccination. Opportunistic vaccination offers the possibility of including individuals excluded from the free vaccination campaigns, often already affected by lesions caused by HPV, providing increased viral clearance and faster lesion regression. The main limit remains the economic burden.
Trois biographies du cura Brochero. Entre hagiographie et histoire, entre oligarchie et gauchos, un personnage significatif dans une Argentine qui se cherche

« Tres biografias del cura Brochera. Entre hagiografia e historia, entre oligarquia y gauchos : un personaje tipico de una Argentina en busca de si misma ».

Segûn la formación que haya recibido quien emplea la palabra, «hagiografia» reviste principalmente dos significados distintos. La palabra nació en contexto claramente católico, puesto que el concepto de santidad, empleado por el pueblo judio antiguo como atributo de Dios, se ha difundido en el mundo católico, a raiz de los misterios de la encamación y de la redención, para aplicarse a todos aquellos que ontológica, psicológica y moralmente, se han dejado transformar por la gracia de Cristo hasta llegar a poder ser propuestos como modelos e intercesores para los fieles. Mientras que para quienes no usen la óptica católica, sino más bien una óptica «universitaria», la palabra se opone a la biografia en que significa más bien la propuesta de un modelo edificante, sin especial preocupación por la verdad histórica de lo que se dice del personaje estudiado. El présente articulo examina très biografias recientes, escritas en el momento en que su proceso de canonización entraba en competencia con el de Ceferino Namuncurá, de José Gabriel del Rosario Brochera, el «cura gaucho» de tras la sierra (de Córdoba, Argentina).
Trois biographies de Juan Rulfo

« Très biografias de Juan Rulfo ».

Este articulo analiza la fortuna editorial de las biograffas de Rulfo a raiz del cincuentenario de la salida de El Llano en Hamas (1953) y Pedro Páramo (1955). A partir del estudio de tres de ellas (firmadas por Nuria Amat, Reina Roffé y Juan Ascensio), se trata de ver los procesos de legitimación y las posiciones adoptados por sus respectivos autores (especialmente en cuanto a la relación establecida con el autor «biografiado»). El ensayo muestra que los autores justifican sus tentativas biográficas tanto por las numerosas mentiras de Rulfo acerca de su vida personal como por su espectacular silencio editorial después de la publicación de sus dos obras maestras.

« Reconstruction des aspects biographiques de la famille dans la collection Los Zambrana, de Malleén Zambrana de Fernandez ».

Le nom Zambrana est celui d'une des familles les plus représentatives de la culture cubaine du XIXe siècle. Dans les cinquante dernières années, l'intérêt pour l'étude des figures de Ramôn Zambrana ou d'Antonio Zambrana a été pratiquement nul. De la même façon, l'intérêt pour Luisa Pérez de Zambrana, une des poètes les plus importantes du Romantisme cubain, a été limité à la répétition d'erreurs biographiques et à la publication de choix des poèmes. Pour l'étude de cette famille, la collection Los Zambrana de Malleén Zambrana de Fernandez représente le meilleur guide ainsi que la meilleure compilation des données biographiques et culturelles. La communication souligne la valeur de cette collection pour la reconstruction de l'élément biographique familial et jette un regard attentif sur le cas spécifique de Luisa Pérez, paradigme de la femme cubaine du XIXe siècle.

Introduction: Healthcare-acquired infections or nosocomial infections are a common problem in all countries. Objectives: The aim of this study was to conduct an epidemiological evaluation of nosocomial infections in Lordegan Shohada hospital from 2017 to 2022. Methods: This study was descriptive-analytical cross-sectional. The case finding was based on Centers for Disease Control (CDC) definitions for nosocomial infection and the nosocomial infection questionnaire of the Ministry of Health and medical treatment of Iran. Cases of nosocomial infection were confirmed based on clinical findings and tests then registered in the Iranian nosocomial infection surveillance system. Results: Overall, 48343 patients were at risk for nosocomial infections during the study period; of these, 274 (0.6%) cases of nosocomial infections were detected, of which 132 were men (48%), and 142(52%) were women. The most common type of nosocomial infection in this study was surgical site infections (0.33%), pneumonia (0.27%), and ventilator-associated events (0.10). The highest rate of nosocomial infection was reported from intensive care units (0.2). Conclusion: The prevalence of nosocomial infections in this center has been low compared to the global norm. This is not the reason that the majority of nosocomial infections are low. The most important reason was the irrational use of antibiotics and, therefore, the hiding of infection cases. The prevalence of microbial resistance is increasing since this issue is worrying in nosocomial infection control.

Published: August 2023

Detecting plant disease is a complicated yet important task to enable sustainable production in agriculture. Especially, early and on-field disease detection provides an opportunity to producers to take necessary precautions before it causes dramatic losses. Corn is one of the most important agricultural products for many countries around the world. It constitutes the main nutrient intake for large populations. This study examines and analyzes the applicability of the pretrained models in corn disease detection. A number of well-known pretrained models including Xception, ResNet50, VGG16, EfficientNetB0, MobileNet and InceptionV3 have been employed for this purpose. SMOTE is employed to solve the imbalanced data and resulting bias problem, which is a common problem in plant disease dataset. The study results indicate that SMOTE provides a good solution to the imbalanced data problem and MobileNet, VGG16 and Xception can be used as base models to develop AI applications to detect corn diseases.

Rüzgâr Enerji Santrali (RES) gibi büyük bütçeli yatırımların değerlemesinde geleneksel yöntemlerin kullanılması kadar reel opsiyonlar yöntemlerinin kullanması da son yıllarda özellikle akademik çalışmalarca desteklenmektedir. Yatırımın ekonomik ömrü boyunca maliyetin, yıllık giderlerin, üretim miktarının ve buna bağlı olarak gelir miktarının, vergi ve enflasyon oranlarının değişiminin piyasa koşullarından ne kadar etkileneceğinin tam olarak bilinmesi imkânsızdır. Gelecek yıllar için de yatırıma ait risklerin ve belirsizlik durumlarının değerleme yöntemine dâhil edilmesi, proje değeri üzerinde olumlu sonuçların alınmasını sağlamaktadır. İndirgenmiş Nakit Akışları gibi geleneksel değerleme yöntemlerinin her yıla ait nakit akışlarını sabit bir iskonto üzerinden indirgemesiyle, koşulların değişmesi durumunda riskin proje değeri üzerinde ki etkisini yok saymaktadır. Bu da sonuç ürün olan proje değerinin değişen koşullara rağmen statik kalması anlamına gelmektedir. Reel opsiyonlarla değerleme yöntemleri riski sabit bir iskonto değeri yerine risksiz faiz oranınca, belirsizliği de değişkenlik parametresi olan volatilite değeri ile denklemlere dâhil etmektedir. Bu durumun geleneksel yöntemlere göre bir üstünlüğü olmakla birlikte, reel opsiyonların değişen piyasa koşullarına göre yatırımcıya erteleme, terk etme, genişleme gibi esneklik seçenekleri sunması da bir başka avantaj olarak görülmektedir. Bu çalışma da Sinop İlinde ki bir RES için reel opsiyon değerleme yöntemlerinden Black-Scholes ve Binomail yöntem ile erteleme, terk etme ve genişleme opsiyonları kullanılarak opsiyon ve proje değerleri elde edilmiş olup, elde edilen sonuçlar her iki yöntem için de karşılaştırılarak yöntemler arası değerlendirme yapılmıştır.

Published: August 2023

Semiconductor photocatalysis is a process that benefits from sunlight to start chemical reactions. In order to take advantage photocatalytic properties of semiconductors and to achieve better performance structural adjustment is needed. In this study, varying amounts of nitrogen were used to modify TiO2 nanostructures using the sol-gel method. The crystalline structure of the synthesized TiO2 nanostructures was studied using the X-ray diffraction (XRD) technique. X-ray photoelectron spectroscopy (XPS) was conducted to analyse the elemental composition of nanomaterials. XPS analyze confirms that nitrogen is introduced into the lattice of TiO2. The photocatalytic degradation of methylene blue (MB) under UV irradiation was employed to assess the photocatalytic performance of the samples. To evaluate degradation, the absorption of MB over time was measured using a UV-Vis spectrophotometer. As a result, the doping process has been found to improve the photocatalytic performance of TiO2, and 0.2% N doped TiO2 nanostructures demonstrated superior photocatalytic activity for photocatalytic degradation of MB.

Análisis de la representación mediática del periódico La Voz de la Mujer
Authors:   , Aguilera Padilla Carolina
Published: August 2023

En el presente trabajo se analizan las representaciones mediáticas que produjo el periódico semi clandestino y de opinión La Voz de la Mujer, editado en la Argentina de finales del siglo xix por mujeres anarquistas con el objetivo de reivindicar la labor y los alcances que solo años después dieron verdaderos frutos. En el marco de la Maestría en Periodismo y Medios de Comunicación, y tomando como referentes de investigación materias y análisis que se hicieron desde la misma, centramos esta investigación en el abordaje de procesos comunicacionales concebidos no solo como difusores de objetivos políticos y sociales que buscaban la ampliación de derechos civiles individuales sino como productores de cambios históricos en el contexto de luchas colectivas, específicamente en la lucha por la liberación femenina. Para explorar la raíz de los discursos y las demandas de las mujeres anarquistas del siglo xix, la propuesta de abordaje de este trabajo se inició con el relevamiento de las ocho únicas ediciones del periódico La Voz de la Mujer que fueron encontradas y compiladas por la Universidad Nacional de Quilmes. Sobre este material, se realizó un análisis de discurso periodístico y se elaboraron categorías que permitieron delimitar las temáticas abordadas por el periódico. Finalmente, el estudio en profundidad de cuatro categorías específicas nos permitió conocer la naturaleza de las representaciones mediáticas que produjo La Voz de la Mujer sobre las demandas y sobre el rol de las mujeres en la Argentina a finales del siglo XIX.

Published: August 2023

For tagua, the quality of the polishing process is analyzed according to the surface finish of the material, which is obtained manually or through empirically developed machinery that does not include the study of the behavior of the material during the process, which generates an inefficient work. The objective of the work is to determine the macro structural properties of tagua nuts to simulate polishing using the discrete element method. Virtual models were developed and the corresponding physical and mechanical properties were assigned. Among the main results, a tagua nut model was achieved, with m=30.22 g and ρ=1327.3±11.23 kg/m3, friction coefficient for wood of µ_e = 0.411±0.0006 and angle of repose of β=24.644º±0.201º. These properties are the variables used as input data for the DEM model. Finally, the suitability of the Hertz-Mindlin model to simulate the process of mechanized polishing of tagua nuts is demonstrated.

Calculation of vehicle insurance premium rates can be done using the aggregate claims model. The aggregate claims model consists of a combination of two independent random variables, namely the number of claims that occur and the amount of claims for each event. The research method is in the form of literature studies and case studies using secondary data in the form of data on the number of claims and the amount of claims collected from January 2013 to December 2019. Based on the data collected, there were 802 claims with the smallest claim being IDR 50,000 and the largest being IDR 211,715,000. Testing the hypothesis shows that the data on the number of claims has a Poisson distribution, and the amount of claims follows two types of distribution, namely the exponential and gamma distribution so that the aggregate claim distribution is a combination of Poisson-Exponential and Poisson-Gamma. Parameter estimation for each distribution is carried out by the moment method with available secondary data. This study concludes that the use of the pure premium principle provides the same premium rate for both distributions of aggregate claims, amounting to IDR 82,856.39 per month per person. While the use of the expected value principle provides a premium rate for the Poisson-Gamma aggregate claims distribution 8.76 times greater than the Poisson- Exponential aggregate claims distribution, namely IDR 1,920,019.55 per month and IDR 219,155.20 per month, respectively.

A New Lightweight Attention-based Model for Emotion Recognition on Distorted Social Media Face Images
Authors: Roy Ayush
Published: August 2023

The recognition of human emotions remains a challenging task for social media images. This is due to distortions created by different social media conflict with the minute changes in facial expression. This study presents a new model called the Global Spectral-Spatial Attention Network (GSSAN), which leverages both local and global information simultaneously. The proposed model comprises a shallow Convolutional Neural Network (CNN) with an MBResNext block, which integrates the features extracted from MobileNet, ResNet, and DenseNet for extracting local features. In addition, to strengthen the discriminating power of the features, GSSAN incorporates Fourier features, which provide essential cues for minute changes in the face images. To test the proposed model for emo-tion recognition using social media images, we conduct experiments on two widely-used datasets: FER-2013 and AffectNet. The same benchmark datasets are uploaded and downloaded to create a distorted social media image dataset to test the proposed model. Experiments on distorted social media images dataset show that the model surpasses the accuracy of SOTA models by 0.69% for FER-2013 and 0.51% for AffectNet social mediad datasets. The same inference can be drawn from the experiments on standard datasets.

Hypothalamic-pituitary-gonadal axis function is necessary for maintaining proper female reproductive cycle. This study aimed to evaluate the ovarian histomorphometric and histoarchitectural changes in neonatal, prepubertal and pubertal thymectomized female guinea pigs. A total of 30 female guinea pigs, sham-operated (n-5) and thymectomized (n-5) were studied in each group. The diameter and number of ovarian follicles among the thymectomized and sham operated female guinea pigs during estrus phase of estrous cycle was compared. Gonadal and accessory reproductive organs weights and microscopic features were studied in the sham operated guinea pigs and thymectomized. There were statistically significant changes in the number and diameter of follicles in the ovary in neonatal thymectomized female guinea pigs, but no significant changes were observed in prepubertal and pubertal female guinea pigs. Neonatal thymectomized female guinea pigs showed significant changes in their weight as well as changes in the microscopic features including reduced thickness of myometrium of uterus and less mucosal folding in the fallopian tube compared to the sham-operated group. But prepubertal and pubertal thymectomy did not affect the weight and microscopic features of gonads and accessory reproductive organs. Depending on the time of thymectomy, these results indicate morphological changes in the ovaries after thymectomy in females.
Inflammatory Bowel Disease (IBD): a novel biological role of saffron petal extracts as a modulator of phlogistic pathway via FBW7/NF-kB in Caco-2 cell line LPS-stimulated
Authors: De Cecco Federica , Franceschelli Sara , Speranza Lorenza
Published: August 2023

Inflammatory bowel disease (IBD) is a chronic pathology characterized by extensive inflammation, which causes a functional alteration of the intestinal barrier. Today most of the drugs applied for IBD have adverse consequences. In this scenario, the development of new therapeutic agents for the treatment of IBD is necessary. A new approach to develop effective therapeutic strategies is the study of natural compounds with anti-inflammatory properties. Saffron petals contain flavonolic glycosides (kaempferol), carotenoids (crocin and crocetin) and anthocyanin pigments, with antioxidant and anti-inflammatory activity. Recently, kaempferol and crocin identified in Saffron Petal Extract (SPE), has been able to reduce oxidative stress in intestinal epithelial cells. Our aim was to evaluate the therapeutic potential of SPE on inflamed human intestinal Caco2 cells that mimic the intestinal microenvironment. We have demonstrated that SPE, down-regulating the expression of the ubiquitine FBW7, inhibits the degradation of the IKB-α subunit and keeps NF-κB in the inactive state. This leads downstream to a reduced activation of inducible molecules (iNOS, COX-2 and HO-1) involved on intestinal inflammatory process. In conclusion, since FBW7 increases in colon tissue of IBD patients, SPE may represent an attractive and promising supplementary treatment for the therapeutic management of IBD with conventional therapies.

A multiple deposition burial in a lithic coffin was found on a hill located in the Campidano valley, in Central South Sardinia (Italy). The site was used from 1800 BC to 500 AD, the burial seems to be dated to the Roman age (238 BC-470AD). A total of 98 human bones and 3 human teeth were present. Anthropological and paleopathological analyses were made. The biological profile was defined with standard anthropological methodologies. The anthropological analysis. A large part of the bones can be referred to as an adult male.  Most of the bones display the presence of pathologies, in most cases osteophytosis, the correlation of the same pathologies in contiguous bones indicate that they may belong to the same individual. Very interesting is a possible blade injury in the lateral epicondyle of the right male humerus and a plausible pertrochanteric fracture. The presence, in the same coffin, of a small number of individuals, with the presence of one subadult, can’t completely exclude that they were members of the same family group. More analyses will be necessary to better understand the context.

Epilepsy is surrounded by stigma and unfavorable attitudes as a result of several inaccurate or insufficient knowledge linked to the disease, and individuals have negative views of the disorder. They must have up-to-date knowledge and an acceptable approach to epilepsy and antiepileptic medications. This study aimed to assess the public general awareness of epilepsy and attitude toward persons living with epilepsy and its associated factors. A descriptive cross-sectional study was undertaken in Taif, Saudi Arabia, targeting the general public with a self-administered validated Arabic questionnaire. The questionnaire, which comprised two sections and included the responder's demographic information, was distributed over social media platforms between March 18, 2022, and June 3, 2022. A total of 500 respondents who met the inclusion criteria were included in the study. The characteristics of the subjects were described using descriptive statistics, and differences were assessed using the independent sample t-test and 2-way ANOVA. A p-value of ≤ 0.05 was used to determine statistical significance. A total of 500 individuals who met the inclusion criteria were included. The mean (standard deviation) score for general epilepsy awareness was 6.78(1.74), which is altogether considered as insufficient. Female participants had a substantially higher mean (SD) awareness score than male participants: 32.58(7.67); 95% CI: 31.34-33.68 versus 29.94(8.79); 95% CI: 28.93-30.95, P0.001. There were no significant differences in participants' awareness scores based on their nationality or occupation. Participants' attitudes towards PWE were mainly favorable, with 482 (96.4%) reporting that they would not be embarrassed if someone in their family had epilepsy, and that PWE should not hide their condition. According to this study, more people are aware of epilepsy and have a good attitude toward it. Furthermore, the study discovered a link between the three variables of interest and ...

Background: Coronavirus disease-2019 (COVID-19), a contagious disease caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), has reached pandemic status, overwhelmed health care systems, strangled the global economy, and led to a devastating loss of life. The presence of cardiovascular comorbidities in COVID-19 patients acts as risk factor for disease severity and is associated with higher rates of cardiac injury, cardiac attack, intensive care unit admission and high mortality. Without pre-existing cardiovascular comorbidities, COVID-19 itself can cause serious heart damage. Serum Anti-SARS-CoV-2 IgG estimation is an important tool for monitoring of COVID-19 patients. Objectives: To assess post COVID-19 Anti-SARS-CoV-2 IgG antibody response in Ischemic heart disease patients. Method: This cross-sectional analytical study was conducted in the Department of Biochemistry, Dhaka Medical College, Dhaka during the period of January 2021 to December 2021. For this study, a total number of 70 diagnosed COVID-19 patients with or without IHD, were selected according to inclusion and exclusion criteria from Cardiology Department (OPD and Indoor) and Post COVID-19 Follow-up Clinic of Dhaka Medical College Hospital, Dhaka. Among 70 subjects, 35 were post COVID-19 with IHD patients (Cases in group-A) and 35 were post COVID-19 without IHD patients (Comparison group in Group-B). By using safety measures, informed written consent was taken from each patient and venous blood sample was collected for estimation of serum Anti-SARS-CoV-2 IgG level. The results were compared statistically between two groups and the significance was defined as p<0.05. Results: Mean ± SD years of age of the subjects in group-A and Group-B were 57.62 ± 11.32 years and 54.14 ± 11.29 years respectively. Majority of patients were in >60 year’s age group followed by 51-60 years. The serum Anti-SARS-CoV-2 IgG level was significantly higher in group-A than Group-B (Median [IQR]: 10786.5 ......

Background: Among the different forms of CNS tuberculosis, tubercular meningitis (TBM) is the most frequent one. Early diagnosis and treatment of tubercular meningitis (TBM) can give an excellent outcome with minimal residual morbidity. Sociodemographic and clinical findings of patients with or without pulmonary signs and symptoms may be useful for the early diagnosis and treatment of suspected TBM patients. Aim of the study: This study aimed to make a sociodemographic and clinical profile of tubercular meningitis patients without pulmonary signs and symptoms. Methods: This was a cross-sectional study that was conducted in the Department of Medicine, Dhaka Medical College Hospital (DMCH), Dhaka, Bangladesh, from September 2020 to August 2021. A total of 77 diagnosed cases of tubercular meningitis without pulmonary signs and symptoms admitted to the mentioned hospital were included in this study as the study population. In sample selection, a purposive sampling technic was used. Along with the sociodemographic as well as clinical findings, all relevant information was recorded in a data collection sheet. After completion, data analysis was done by SPSS 23.0. Results: The mean age of our respondents was 37.93±11.8 years; 53.2% of them were male and 46.8% were female. The majority of the respondents were service holders (32.5%) and the majority (57.1%) of the patients had middle-family income. In this study, 61% of the study population had a family history of TB. As for the clinical features of TBM, we observed that all of the study subjects had a fever, 80.5% had a headache, 68.8% had altered sensation, 62.3% had anorexia and nausea, 55.8% had vomiting, 19.5% had convulsions and 15.6% had neck stiffness. The majority (46.8%) of the respondents had TBM Grade II. In total, 58.4% of the respondents had Mantoux test positive and 41.6%, whereas 36.4% showed chest X-ray positive for TB. Conclusion: The prevalence of tubercular meningitis without pulmonary signs and ........

Aim: To compare shear bond strength of resin composite cement to coronal enamel, cementoenamel junction and root cementum. Materials and Methods: Twenty one extracted human permanent teeth were selected and randomly divided into three groups(n=21) according to area of adhesion. group 1(n=7): coronal enamel. group 2(n=7): cementoenamel junction. group 3(n=7): root cementum. An area of 5mm x 5mm was selected on tooth of each specified group. Area was etched for 15 seconds with 35% phosphoric acid and washed off. Bonding agent was applied on area and light cured, composite was applied and light cured for 30 seconds. Teeth were mounted in acrylic resin and stored in distilled water. Specimens were subjected to shear load using universal testing machine at cross head speed of 0.5mm/min. Results: According to results obtained from the study comparative shear bond strength (in Mpa) of resin composite cement to coronal enamel, cementoenamel junction and root cementum, highly statistically significant (p<0.001) difference was observed among three groups. Discussion: The cervical area of teeth is most unpredictable region for durable adhesive bonding. This study was performed to evaluate adhesion potential of composite cement to coronal and cervical structures of teeth. Conclusion: Under this study, we can conclude that adhesion to root cementum is less favorable compared to adhesion to CEJ and coronal enamel.

Leakages in pipeline is an important problem that can occur at any stage of the pipeline lifespan due to ageing, improper installation, or human related factors like bunkering or vandalization. Several invasive and non-invasive techniques are being used which have proven to be successful. However, this study focuses on leakage in an area of the pipeline network that is most often overlooked. This area is within the first 100 meters of the pipeline network to the excitation pump and is often prone to leakages due to high pressure. This study shows that even at no leak conditions pressure profile of a short pipeline in a closed loop configuration can vary by as much 59.93 percent. The study also examined the impact of single leak, double leaks, and triple leaks on the pipeline network with pressure loss compared to the no leak condition ranging from about 10 percent to as high as 60 percent.
Drug Resistant Tuberculosis: A Major Risk to Global Health Security Treatment

Published: August 2023

The continuing spread of drug-resistant tuberculosis (TB) is one of the most urgent and difficult challenges facing global TB control. Patients who are infected with strains resistant to isoniazid and rifampicin, called multidrug-resistant (MDR) TB, are practically incurable by standard first-line treatment. In 2012, there were approximately 450,000 new cases and 170,000 deaths because of MDR-TB. Extensively drug-resistant (XDR) TB refers to MDR-TB strains that are resistant to fluoroquinolones and second-line injectable drugs. The main causes of the spread of resistant TB are weak medical systems, amplification of resistance patterns through incorrect treatment, and transmission in communities and facilities. Although patients harboring MDR and XDR strains present a formidable challenge for treatment, cure is often possible with early identification of resistance and use of a properly designed regimen.
