This work studies the relationship between accretion-disk size and quasar properties, using a sample of 95 quasars from the Sloan Digital Sky Survey Reverberation Mapping Project with measured lags between the g and i photometric bands. Our sample includes disk lags that are both longer and shorter than predicted by the Shakura and Sunyaev model, requiring explanations that satisfy both cases. Although our quasars each have one lag measurement, we explore the wavelength-dependent effects of diffuse broad-line region (BLR) contamination through our sample’s broad redshift range, 0.1 < z < 1.2. We do not find significant evidence of variable diffuse Fe ii and Balmer nebular emission in the rms spectra, nor from Anderson–Darling tests of quasars in redshift ranges with and without diffuse nebular emission falling in the observed-frame filters. Contrary to previous work, we do not detect a significant correlation between the measured continuum and BLR lags in our luminous quasar sample, similarly suggesting that our continuum lags are not dominated by diffuse nebular emission. Similar to other studies, we find that quasars with larger-than-expected continuum lags have lower 3000 Å luminosities, and we additionally find longer continuum lags with lower X-ray luminosities and black hole masses. Our lack of evidence for diffuse BLR contribution to the lags indicates that the anticorrelation between continuum lag and luminosity is not likely to be due to the Baldwin effect. Instead, these anticorrelations favor models in which the continuum lag increases in lower-luminosity active galactic nuclei, including scenarios featuring magnetic coupling between the accretion disk and X-ray corona, and/or ripples or rims in the disk.

Published: January 2024

Introduction: Mycobacterium abscessus is an opportunistic nontuberculous mycobacteria pathogen; however, the prevalence of nosocomial and community infections is increasing. In January 2016, several bedridden inpatients in the intensive care unit of a hospital had positive sputum smears for acid-fast bacilli, suggesting a mycobacteria outbreak.
Methodology: Acid-fast bacilli smear microscopy, isolation, and culturing were performed twice using sputa from each suspected intensive care unit inpatient (n = 13); in addition, medical history was obtained for each inpatient with suspected infection. Furthermore, environmental specimens were surveyed, collected, and cultured. We used DNA microarray chip analysis to identify positive mycobacterial isolates at the species level and performed whole-genome sequencing and phylogenetic tree construction.
Results: Seven inpatients had M. abscessus pulmonary infection, confirmed by 2 positive cultures; five of the inpatients had only one positive culture, while one had two negative cultures. Six of 13 ventilator condensate samples were mycobacterial culture-positive, identified as M. abscessus; the other environmental samples were negative. The M. abscessus isolates (15 sputa and 4 environmental samples) clustered together in the phylogenic analysis with only one single-nucleotide polymorphism difference. All patients were symptom-free after 8 months of multi-drug treatment.
Conclusions: We confirmed a pulmonary M. abscessus outbreak among 12 bedridden patients in the intensive care unit through microbiological, molecular epidemiological, and environmental investigations. The possible infection source was contaminated ventilator condensate. This outbreak reemphasizes the importance of standardized ventilator maintenance and disinfection for preventing ventilator-associated pneumonia and is a reminder that nontuberculous mycobacteria-related ventilator-associated pneumonia is possible.

Objectives: Sepsis is a common disease with a high mortality. Decreasing the speed is possible with early and intensive therapy. However, most medicines have been tested, but none has proven effective. Therefore, the study aimed to discover the protective and therapeutic effects of pomegranate seed oil (PSO).
Methods: The cecal ligation puncture (CLP) method was used to induce sepsis. The experimental procedure was started with the animals divided haphazardly into four groups: control (C), sepsis (CLP), CLP + low dose PSO (CLP + LD), and CLP + high dose PSO (CLP + HD). First, the cecum was filled with feces. The full cecum was tied under the ileocecal valve for ligation and punctured. At 1 hour after CLP, 0.32 mg/kg and 0.64 mg/kg of PSO were administered. 24 hours after, lung and kidney specimens were collected.
Results: Neutrophil infiltration/aggregation and alveolar wall thickness decreased in lung with PSO groups compared with the CLP. The findings for overall lung injury were similar. In renal, all parameters were increased in the CLP compared with C, except for vascular vacuolization and hypertrophy. According to the CLP, all parameters were significantly lower in CLP + HD. Furthermore, glomerular vacuolization, degeneration, and necrosis of tubular cell, dilatation of bowman space, and tubular hyaline cylinders reduced CLP + LD versus CLP. Thiobarbituric acid-reactive substances decreased in lung, with the PSO groups. In addition, superoxide dismutase increased in PSO groups versus CLP.
Conclusions: We conclude that the high-dose PSO is especially effective in treating sepsis.

Introduction: Tuberculosis (TB) is a re-emerging disease considered a public health concern. In the present study, we analyzed the epidemiology and drug resistance of Mycobacterium tuberculosis strains isolated from patients with pulmonary TB.
Methodology: Mycobacterium tuberculosis isolates (n = 190) were obtained from patients with pulmonary TB admitted to Dr. José Eleuterio González University Hospital (UH). Each M. tuberculosis isolate was analyzed by spoligotyping (spacer oligonucleotide typing) and MIRU-VNTR (Mycobacterial Interspersed Repetitive Units-Variable Number Tandem Repeat). Drug resistance was evaluated using the Anyplex™ II MTB/MDR/XDR assay.
Results: The predominant spoligotypes observed were X1 (SIT 119, n = 46), T1 (SIT 53, n = 40), H3 (SIT 50, n = 13), Beijing (SIT 1, n = 11), and EAI2-Manila (SIT 19, n = 8). MIRU-VNTR analysis showed that the locus QUB-26 had the highest allelic variability. The observed drug resistance included monoresistance to rifampicin (2.6%; n = 5), isoniazid (3.2%; n = 6), and fluoroquinolones (1.6%; n = 3) as well as multidrug resistance (5.3%; n = 10). All of the Beijing strains were susceptible. Regarding comorbidities, 13.7% (26/190) of the patients were co-infected with TB and HIV (TB+HIV+), and 31.6% (55/190) had TB along with diabetes (TB + diabetes).
Conclusions: The most prevalent lineages were X1 (SIT 119; 24.3%) and T1 (SIT 53; 21%). An alarming proportion (12.6%) of M. tuberculosis isolates presented drug resistance. To effectively manage TB, continuous surveillance of regional strain dissemination, drug resistance profiles, and TB-associated comorbidities is crucial.

Published: January 2024

Introduction: Our study aimed to analyze virus-specific humoral immune responses in COVID-19 patients with varying disease severity.
Methodology: A total of 109 serum samples from 87 patients, symptomatic for COVID-19 were studied using anti-SARS-CoV-2 immunoassays detecting different classes of immunoglobulins.
Results: Clinical samples were divided into 2 groups - collected up to and more than 2 weeks post-onset of symptoms (PoS). In the first group, the highest percentage of positive samples was found for IgA class virus-specific antibodies (78.1%), followed by IgM (71.9%/59.4%) and IgG (56.3%/53.1%). In the second group, samples positive for virus-specific IgA class antibodies were also the most (97.7%) along with those positive for IgG. A total of 72 IgA and/or IgM and/or IgG positive samples were further tested for SARS-CoV-2 neutralizing antibodies (NAbs) - 89.1% and 100% of samples obtained up to and after 2 weeks PoS, respectively were positive. Serological test results were also analyzed depending on the severity of the disease - SARS-CoV-2 positive samples in mild forms of COVID-19 were fewer than in moderate and severe forms but this difference was not statistically significant.
Conclusions: SARS-CoV-2 specific antibodies and a high virus neutralization capacity of these antibodies appear early PoS; Immunoglobulins of IgA class are of most significant diagnostic value for detection of SARS-CoV-2 infection; Timing of testing is the most important factor for positivity rate.

Published: January 2024

Introduction: HCMV infection is widespread in humans. This retrospective study aimed to explore the relationship between human cytomegalovirus (HCMV) glycoprotein B (gB) genotype distribution, viral load, and the demographic and clinical features of symptomatic infants. The detection rate of HCMV in blood and urine samples was also compared.
Methodology: Retrospective data from 265 infants who underwent urine HCMV DNA testing were analyzed. The viral load and gB genotype were detected in 91 HCMV positive infants by quantitative fluorescence polymerase chain reaction (PCR) and DNA sequencing, respectively.
Results: The positive rate of HCMV infection was 46.04% (122/265) in all infants, and increased rapidly with age. Among the 91 infants investigated, liver function abnormality was the most common diagnosis (34/91, 37.36%), followed by pneumonia (21/91, 23.07%). Sequence analysis of gB yielded two genetic subtypes: the most prevalent gB3 (47/91, 51.65%), followed by gB1 (44/91, 48.35%). The gB3 HCMV infection was more prevalent in infants aged 0-2 months than in infants aged 3-12 months (χ2 = 4.38, p = 0.0364). The data showed that ALT and AST levels were significantly higher in the anti-HCMV IgM+IgG– group than in the anti-HCMV IgM+IgG+ and IgM-IgG+ groups. In addition, this study showed that the detection rate of HCMV DNA in the blood was significantly lower than that in the urine (χ2 = 6.7131, p = 0.0096).
Conclusions: This study presents the HCMV infection status of infants and its relationship with their demographic characteristics and clinical manifestations. In addition, this study suggests that urinary PCR is the most appropriate assay for detecting HCMV infections.

Black queer folks, especially Black queer womxn, have always existed in Christian church spaces. For many, they are allowed to bring our talents to our places of worship–provided that they do not bring their whole queer selves. Additionally, Black queer womxn exist in these spaces but are often punished for bringing all our queerness to the table. When the intersections of church and higher education manifest as religiously affiliated institutions, Black queer womxn struggle to be seen and validated in many ways. As two Black queer womxn at a religiously affiliated doctoral institution, the authors are curious how they navigate their multiple oppressions, especially those highlighted in religious spaces. Their question is: What are the experiences of Black queer womxn at a religiously affiliated institution? The authors attempt to answer this question by the use of duoethnography to examine our experiences as Black queer womxn who are doctoral students at a religiously affiliated institution.

Even the technology has profoundly changed the way consumer process communication. In the last few years the internet has played a major role in many fields of economy as it is commonly defined as a global media. The internet has been largely used in commerce and management. Electronic commerce, commonly written as e-commerce or E-Commerce, is the trading or facilitation of trading in products or services using computer networks, such as the Internet. The rapid adoption of the Internet as a commercial medium has caused firms to experiment with the innovative ways of commerce thus changing the pattern of commerce strategies.

The primarily motive of the study was to investigate the awareness level of respondents regarding the regulatory framework of E-Commerce. The present study was exploratory research by the means of primary data analysis wherein an attempt was made to identify the awareness level of respondents regarding regulatory framework of e-commerce with the help of self structured questionnaire. The questionnaire was based on the five point Likert scale ranging from not at all aware to completely aware and the convenience sampling was used to collect the data from respondents (250) residence of Punjab and Union Territory of Chandigarh. Further, chi square technique was used to test the null hypothesis as whether there was significant relationship between regulatory framework, gender and monthly income attributes. It was observed that female respondents were more aware as compared to male respondents regarding the regulatory framework of e-commerce. On the basis of monthly income attribute, 15000-30000 income group’s respondents were not aware regarding the regulatory framework of e-commerce but in the next income group ranging from 50000-75000 were aware about the regulatory framework of the e-commerce.

Authors: Assunção Victor , Bizarra Fátima , Simões Raquel
Published: January 2024

Introdução: A sustentabilidade na higiene oral deve ser uma preocupação, mantendo a qualidade e eficácia dos produtos escolhidos, para uma boa saúde oral. Existem atualmente diversos formatos de dentífricos sustentáveis como é o caso das pastilhas, com ingredientes naturais e menor pegada de carbono para o ambiente. Objetivo: Avaliar a satisfação na utilização de pastilhas dentífricas fluoretadas DENTTABS®. Metodologia: Realizou-se um estudo clínico aleatorizado cruzado, com dois grupos de participantes, em que cada grupo foi exposto a ambas as intervenções: 14 dias de uso do dentífrico fluoretado habitual e 14 dias de uso das pastilhas dentífricas fluoretadas. Três questionários foram entregues a cada participante, o primeiro no baseline e os restantes após a utilização de cada dentífrico. O primeiro questionário referia-se à caracterização sociodemográfica e hábitos de higiene oral; o segundo referia-se à satisfação no uso da sua pasta dentífrica; e o terceiro referia-se à satisfação do uso de pastilhas DENTTABS®. Os dados foram analisados no software SPSS® versão 27. Resultados: No estudo participaram 39 pacientes, maioritariamente mulheres, com uma média de idades de 36 anos e o nível de escolaridade predominante foi o bacharelato/licenciatura. A maioria dos participantes escova duas vezes ao dia e os atributos que mais valorizaram nos dentífricos foram dentes e gengivas saudáveis. Apesar das pastilhas dentífricas serem diferentes do dentífrico convencional, 71,8% afirmaram sentirem-se satisfeitos com a sua eficácia. As características mais valorizadas das pastilhas foram o efeito de polimento nos dentes, o facto de serem unidoses com uma boa quantidade de dentífrico, prático transporte e sabor a mentol. As características menos agradáveis das pastilhas foram a ausência de espuma, consistência da pastilha e sabor. A autopercepção da motivação ao usar um novo produto foi referida por 64,1% como igual à motivação da utilização da sua pasta dentífrica habitual. A maioria dos participantes recomenda a utilização das pastilhas dentífricas. Conclusão: As pastilhas dentífricas apresentam um elevado grau de satisfação, comparativamente à pasta dentífrica convencional, sendo uma boa opção de dentífrico e mais amigo do ambiente.

A análise estatística incluiu teste Mann-Whitney e regressão linear múltipla (método stepwise). Resultados: A amostra (n=99) maioritariamente feminina (71,7%) e com idade média de 29,69(±6,73) anos, apresentou pobre qualidade de sono (5,48±7,63). Existem diferenças significativas entre a qualidade de sono de trabalhadores com e sem queixas de dor lombar, tanto no grupo dos trabalhadores sem turnos (p=0,042), como no grupo com turnos (p=0,033), sendo que estes apresentam pior qualidade de sono. A variância da qualidade do sono pôde ser explicada em 18% (r quadrado ajustado=0,180; Durbin Watson=2,065; Z=7,865; p<0,001) pela variância da dor lombar (Beta=0,336; p<0,001), sexo (Beta=-0,239; p= 0,014) e IMC (Beta=0,201; p=0,038). Conclusão: Este estudo sugere alguma influência da dor lombar na qualidade de sono de trabalhadores com e sem turnos, e também sugere que o aumento do IMC, ser do sexo feminino e apresentar dor lombar podem predizer uma pobre qualidade do sono em trabalhadores.

Authors: Namudhiba Catherine , Ssendagi Muhamad
Published: January 2024

Aim
To determine the relationship between head teachers’ support supervision and teachers’ classroom Instruction and management in Primary schools in Kigulu North constituency, Iganga District
 Methods
A descriptive cross-sectional study was used, with both quantitative and qualitative methods of data collection and analysis. Questionnaires were used for the teachers and administrators while in-depth interviews were done for upper-class pupils. Descriptive statistics were used to analyze the findings and quantitative data were analyzed by SPSS version 22.
 Results
The findings revealed a strong positive significant relationship between head teachers’ supervision and teachers’ classroom Instruction and management (r=0.553). This was reflected by a correlation that is significant at the 0.01 level (2-tailed). 0.01 level (2-tailed).
 Conclusion
The findings reflect that head teachers’ support supervision influences teachers to track teachers' lesson plans daily and give constructive feedback; to ensure that schemes of work and lesson plans are approved before the teaching and learning process; and that required scholastic materials are provided, all the teachable units for every class and term are schemed as a way of monitoring syllabus coverage, required learning aids are provided.
 Recommendation
 Headteachers should not shy away from supervising teachers’ schemes of work and lesson plans. This should be emphasized during appraisal sessions to help improve teacher effectiveness and hence student learning. There is a need to ensure that teachers are always supervised daily to instill commitment and hard work which would in turn lead to improved teachers’ performance in primary schools.

Authors: Manisuuri Kintu , Bakashaba Edmand , Ssendagi Muhammad
Published: January 2024

Background
This study aims to document the feeding practices of pupils in primary schools in Kayunga district, central Uganda. Feeding is the provision of meals to a person or animals. In children, feeding occurs in the context of the caregiver-child dyad. Feeding practices in this context are arrangements of providing food to school children. For this study, feeding practices are home-packed food, school-prepared food, and commercialized food outlets. Feeding practices are an important determinant of children’s nutritional status, which is directly related to the risk of becoming sick and dying. Kayunga district is one of the districts in the central region of Uganda with many pupils as the leading population of learners. Therefore, feeding is one of the basics to support an education. Therefore, this study seeks to assess the feeding practices of pupils in primary schools in Kayunga district, central Uganda.
Methodology
This study used a descriptive cross-sectional correlational survey design and adopted a mixed research approach.
Results
The findings showed that 59% of the pupils were getting meals prepared at school, 36% of the pupils get meals from home and 5% of the pupils are getting meals from food outlets.
Conclusion
There were three main feeding practices in primary schools in Kayunga District. Namely; package food from home, school arranged feeding and food from outlets like canteen and restaurants. The study documented that among the three main feeding practices, most pupils are fed from school on the school management arrangements in Kayunga District.
Recommendation
Schools should also provide storage places for meals of students. This will help students to have meals at the appropriate time and use available time to read without interruptions.

Authors: Opela Stephen , Bakashaba Edmand , Noel Henry
Published: January 2024

Background
Indiscipline can be defined as failure to obey rules and orders or lack of control in the behavior of a person or group of people. Indiscipline cases in schools have been an issue of concern for educators and have become a huge concern among educators, policymakers, and the public in general.  This study aimed to document the types of indiscipline in secondary schools in Pallisa Town Council.
Methodology
The study adopted a triangulation of a case study design and a cross-sectional survey design. The study also uses a mixed research approach where both qualitative and quantitative techniques were used to analyze data. A case study design was employed because the researcher did not have enough time or financial resources to conduct a national survey of all secondary schools in Uganda. To collect primary and secondary data three methods were used. A self-administered questionnaire and interview method were used to collect primary data while the documentary review was used to gather secondary data.
Results
According to findings, there are three types of indiscipline in secondary schools in Pallisa district. These were minor, major, and intolerable indiscipline behaviors. The minor behaviors were; Noise-making in class, Absenteeism, and Loitering on school premises. The major indiscipline behaviors were; missing classes, Smoking, Habitual lateness, and drinking alcohol. The intolerable indiscipline behaviors were; Physical violence, Vandalism, Use of drugs, and Bullying.
Conclusion
The major indiscipline behaviors were; missing classes, Smoking, Habitual lateness, and drinking alcohol.
Recommendation
More studies should be done on the causes of indiscipline among students.
Teachers should create a more friendly atmosphere for learners to reduce indiscipline.
Using statistical models to depict the response of multi-timescale drought to forest cover change across climate zones

Abstract. The interaction between forest and climate exhibits regional differences due to a variety of biophysical mechanisms. Observational and modeling studies have investigated the impacts of forested and non-forested areas on a single climate variable, but the influences of forest cover change on a combination of temperature and precipitation (e.g., drought) have not been explored, owing to the complex relationship between drought conditions and forests. In this study, we use historical forest and climate datasets to explore the relationship between forest cover fraction and drought from 1992–2018. A set of linear models and an analysis of variance approach are utilized to investigate the effect of forest cover change, precipitation and temperature on droughts across different timescales and climate zones. Our findings reveal that precipitation is the dominant factor (among the three factors) leading to drought in the equatorial, temperate and snow regions, while temperature controls drought in the arid region. The impact of forest cover changes on droughts varies under different precipitation and temperature quantiles. Precipitation modulates forest cover's impact on long-term drought in the arid region, while temperature modulates the impact of forest cover changes on both short- and long-term drought in the arid region as well as only on long-term drought in the temperate region. Forest cover can also modulate the impacts of precipitation and temperature on drought. High forest cover leads to a combined effect of precipitation and temperature on long-term drought in arid and snow regions, while precipitation is the only dominant factor in low forest cover conditions. In contrast, low forest cover triggers a strong combined effect of precipitation and temperature on drought in the temperate region. Our findings improve the understanding of the interaction between land cover change and the climate system and further assist decision-makers to modulate land management strategies in different regions in light of climate change mitigation and adaptation.

Authors: Mafla Alejandra , Zambrano Eduardo , Álvarez Johanna
Published: January 2024

Introducción: La intususcepción es una patología abdominal idiopática o secundaria a procesos intestinales que actúan como puntos de partida para la invaginación. Se han descrito casos de arrastre de estructuras que derivan en otros procesos inflamatorios como la apendicitis aguda.
Caso clínico: Niño 3 años, con dolor abdominal de 6 horas de evolución. Al examen físico se presenta pálido, somnoliento, taquicárdico y deshidratado. El abdomen con signos apendiculares positivos, con palpación en masa en fosa iliaca derecha.
Taller diagnóstico: Leucocitos 9690 u/mm3, neutrófilos 58.1%. Ecografía con imagen sugerente de intususcepción intestinal con cambios inflamatorios en la grasa mesentérica. Se realiza tomografía abdominal que reporta intususcepción ileocolónica de 47 x 50 mm, con múltiples ganglios reactivos mesentéricos, con imagen apendicular en dirección pélvica, con apendicolito en su interior.
Evolución: El manejo quirúrgico incluyó una laparotomía exploratoria con desinvaginación manual y apendicectomía convencional. El reporte de patología fue apendicitis aguda supurativa. El paciente 48 horas hospitalizado, recibió Ampicilina + Sulbactam y analgesia. Al mejorar la función abdominal fue dado de alta.
Conclusiones: En este caso la apendicitis aguda fue la causa de intususección intestinal con el signo ecográfico de la “diana” en un paciente de 3 años de edad.
