Massive-Scalar Effective Actions on Anti-de Sitter Spacetime

Closed forms are derived for the effective actions for free, massive spinless fields in anti-de Sitter spacetimes in arbitrary dimensions. The results have simple expressions in terms of elementary functions (for odd dimensions) or multiple Gamma functions (for even dimensions). We use these to argue against the quantum validity of a recently-proposed duality relating such theories with differing masses and cosmological constants.Comment: 23 pages, plain TeX, one figur

Leadership Style, Competence and Job Satisfaction: Determinants of Performance

In tertiary institutions, the lecturer factor greatly determines the quality of education and is an important resource in educational services. Lecturers are an important component in improving the quality of education. In terms of academic development for students, lecturers have a strategic role in higher education. Based on professional considerations, lecturers are professionals who determine what is best for students. The quality of lecturers determines the development of the quality of education. The key factor that determines the strength of education is the lecturer. This study aims to examine the effect of the determinants of lecturer performance, namely leadership style, competence and job satisfaction. The number of samples in the study was 100 lecturers where the determination of the number of samples used the Slovin formula. Based on the test results found that competence has an effect on performance, leadership style and job satisfaction have no effect on performance.

Pengabdian Kepada Masyarakat  telah dilakukan dengan memberikan pelatihan terhadap ibu-ibu anggota  Majelis Ta’lim. Pelatihan yang diberikan adalah membuat kerajinan rajutan tangan. Dalam pelaksanaan kegiatan, para ibu-ibu sangat antusias dalam menyimak penjelasan dan peragaan dari narasumber dan melalui tayangan video. Berbagai model rajutan diajarkan sehingga akan mempermudah mereka dalam membuat berbagai macam rajutan sehingga dapat menumbuhkan semangat berwirausaha dalam meningkatkan pendapatan keluarga.  Abstract: Koto tangah district is the most densely populated sub-district.  This sub-district has a large enough female population. empowering women is very important to have an entrepreneurial spirit in developing a productive economy. Empowering women to increase access to knowledge and skills, so as to improve family welfare. Skills training activities are expected to have an impact on women's ability to create employment. through training in knitting skills, women can produce knitted products of economic value. The partner chosen was the community group members of the al-ikhlas mosque assembly council in dadok tunggul hitam village, koto tangah district. most of the mothers who joined the ta'lim assembly with 40 members were housewives who generally did not work and had relatively low incomes. Community service  has been carried out by providing training to women members of the ta'lim assembly to develop their economy. The training provided is making hand-knitted crafts. in carrying out the activity, the mothers were very enthusiastic in listening to the explanation and demonstration from the speakers and through the video. Various knitting models are taught so that it will facilitate them in making various kinds of knits so as to foster an entrepreneurial spirit in increasing family income.

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

The status of antioxidant defences in Glucose-6-phosphate dehydrogenase deficient patients. The role of antioxidants to ameliorate hemolytic crisis

In human, G6PD deficiency is the most common enzymopathy affecting over 400 million people throughout the world. It is associated with higher potential for oxidative damage due to chronic redox imbalance in red cells that often results in clinical manifestation of mild to severe hemolysis. The NADPH product of G6PD is required for the reductive biosynthetic reactions as well as for the stability of catalase, and the preservation of the reduced form of glutathione (GSH). The aim of this study was to clarify the role of G6PD in cellular antioxidant defense; the level of glutathione, catalase, NADPH and estimate the level of malondialdehyde which reflect the oxidative stress across the cell membrane. Also to study the effect of antioxidant treatment (vitamins C and E) to ameliorate high sensitivity of red cells to oxidative stress. This study was carried out on fifty G6PD-deficient children during the attack. The children were classified into two groups: Group 1: received blood transfusion only, and considered as an antioxidant-untreated group. Group 2: Received blood transfusion as group I in addition to antioxidant therapy (antioxidant-treated group), and healthy control subjects as control group. Our study proved that hemolytic attack in G6PD deficient patients is due to a concomitant impairment of the two main mechanisms of detoxification of H2O2 in RBCs; GSH system and catalase. The most important finding in this study is the efficiency of treatment with a combination of vitamin E and vitamin C may improve antioxidant status in G6PD deficient patients and in reducing the symptoms of hemolytic crises.Egyptian Journal of Biochemistry and Molecular Biology Vol. 25 (2) 2007: pp. 114-13
