Published: June 2022

Heart failure is a chronic disease that spoils patients' quality of life (QoL) and is associated with both high hospital readmission rates and healthcare resource utilization such as emergency services. The purpose of this study is to measure the quality of life using the validated Minnesota Living with Heart Failure Questionnaire (MLWHF). The study used a non-experimental, quantitative design with a theoretical framework based on health-related quality of life among heart failure patients. A simple random sampling method was used, which covered the medical and cardio clinics in two tertiary and secondary hospitals. The overall data were collected for four weeks from these hospitals. The total number of respondents in this study was 200. SPSS version 25.0 was used to analyse the data. The instrument was composed of three components, and the first component included eight items that measured the patients’ physical aspects. The second component measured other aspects that comprised eight items that covered social, work, and sexual topics, and the final component measured emotional aspects with five items. The overall MLHFQ scale consisted of 21 items. MLHFQ was translated into the Malay language by using back-to-back translation procedures by experts in their fields. The results of the exploratory factor analysis (EFA) found that all 21 items were accepted due to factor loading being more significant than 0.6. However, question number 16part three relaying other aspects had a factor loading of only 0.67. As a result, for local use, this instrument needs to rearrange the items measuring the construct into their respective components accordingly before proceeding with data collection in the field study. In conclusion, for local content, this instrument needs to rearrange the items measuring the construct into their respective components accordingly before proceeding with data collection in the field study.
Simulation and Measurement of Pressure Rise in GIS 145 kV due to Internal Arcing

Published: June 2022

Internal arc testing of metal-enclosed, SF6 gas insulated switchgear (GIS) is defined by IEC 62271-203 and is not a part of mandatory type tests.
However, due to the increasing demands on the safety of personnel, more often the implementation of this test is required in the tender documentation. According to IEC, the duration of the electric arc is related to the performance of the protective system determined by the first and second stage of protection. For the rated short-circuit current equal or higher than 40 kA, during the first stage of protection (0.1 s), no external effects on enclosure other than the operation of pressure relief device is permitted. During the second stage of protection (≤0.3 s) no fragmentation is permitted, but burn-through is acceptable. The test should be carried out on the GIS compartment with the smallest volume at nominal gas pressure. Since a newly developed GIS 145 kV is designed as a three-phase encapsulated, arc initiation is achieved by short connecting of all three phase conductors in the vicinity of a partition by means of a thin metal wire. This ensures that two electric arcs burn simultaneously commutating between the phases, so the possibility of enclosure burn-through in this type of GIS is minimized. In order to prevent the release of SF6 gas in the atmosphere during the testing, a test enclosure should be placed in a protective gastight enclosure filled with air or more often SF6 gas at pressure of 0.1 MPa. This test object configuration significantly complicates the pressure rise calculation and increases the testing cost. In order to prevent enclosure fragmentation, the pressure difference between the test enclosure and the protective enclosure during the test should always be less than the bursting pressure of test enclosure. Also, the protective enclosure should be designed to withstand the maximum pressure rise that may occur after pressure relief device opens. In order to assess the likelihood of passing the upcoming type test for newly developed GIS, a computer program for calculation of pressure and temperature in the test enclosure and protective enclosure was developed. The mathematical model is based on the paper of the working group CIGRE A3.24, published in 2014. The basic model shown in the paper is enhanced by the real properties of the SF6 gas/plasma, evaporation of the electrode material and the insulator ablation. The contribution of exothermic/endothermic reactions between the gas and the electrode material on the pressure and temperature rise was also considered. At the same time, the measurements of pressure rise in GIS enclosure and protective enclosure were carried out in Končar High Power Laboratory. The experiments performed on a copper and aluminum electrodes in SF6 gas confirmed significantly higher contribution of aluminum electrodes to the pressure and temperature rise compared to the copper electrodes. The computer program is verified by measurement results.

Yaşlılık çalışmalarında temel bir disiplin olan mekân gerontolojisi, ilk yıllarda ekolojik perspektif etrafında ele	alınırken, son zamanlarda ise eleştirel bakış açısı merkeze alınarak tartışılmaya başlanmıştır. Bunun altında yatan	sebeplerden bir tanesi günümüz kentlerinin Neoliberal politikalar etrafında şekillenmeye başlamasıdır. Neoliberal	rasyonalite ile üretilen kentlerde yaşam kalitesinin anlamı tüketime göre şekillenmekte ve var olan eşitsizlikler daha	da derinleşmektedir. Bu eşitsizliklerden etkilenenler arasında yaşlıların da olduğu görülmektedir. Bugünün	Neoliberal ekonomi politiği yaşlılığı yoksulluk ve dezavantajlılık üzerinden yeniden şekillendirmektedir. Fakat kentsel	konularda yaşlılar genellikle görünmez bir özne konumundadır. Bu çalışmada yaşlılık ve mekân arasındaki ilişki, kent	sosyolojisi ve gerontoloji disiplinlerinin sunduğu bakış açıları ve imkânları bir araya getirilerek ele alınmaktadır. İki	disiplin arasında kuramsal bir bağın oluşturulabileceğine ve mevcut durumun bu bağlamda tartışılabileceğine	odaklanılmaktadır. Son olarak ise bu bakışın işaret ettiği toplumsal ve mekânsal bağlam karşısında bir çözüm önerisi	olarak hak temelli yaklaşımları tartışmaya açılmaktadır.

Abstract
Cool stars on the main sequence generate X-rays from coronal activity, powered by a convective dynamo. With increasing temperature, the convective envelope becomes smaller and X-ray emission fainter. We present Chandra/HRC-I observations of four single stars with early A spectral types. Only the coolest star of this sample, τ

Published: June 2022

Abstract
The substructures observed in protoplanetary disks may be the signposts of embedded planets carving gaps or creating vortices. The inferred masses of these planets often fall in the Jovian regime despite their low abundance compared to lower-mass planets, partly because previous works often assume that a single substructure (a gap or vortex) is caused by a single planet. In this work, we study the possible imprints of compact systems composed of Neptune-like planets (∼10–30 M
⊕) and show that long-standing vortices are a prevalent outcome when their interplanetary separation (Δa) falls below ∼8 times H
p—the average disk’s scale height at the planet’s locations. In simulations where a single planet is unable to produce long-lived vortices, two-planet systems can preserve them for at least 5000 orbits in two regimes: (i) fully shared density gaps with elongated vortices around the stable Lagrange points L
4 and L
5 for the most compact planet pairs (Δa ≲ 4.6 H
p), and (ii) partially shared gaps for more widely spaced planets (Δa ∼ 4.6–8 H
p) forming vortices in a density ring between the planets through the Rossby wave instability. The latter case can produce vortices with a wide range of aspect ratios down to ∼3 and can occur for planets captured into the 3:2 (2:1) mean-motion resonances for disks’ aspects ratios of h ≳ 0.033 (h ≳ 0.057). We suggest that their long lifetimes are sustained by the interaction of spiral density waves launched by the neighboring planets. Overall, our results show that the distinguishing imprint of compact systems with Neptune-mass planets are long-lived vortices inside the density gaps, which in turn are shallower than single-planet gaps for a fixed gap width.

Abstract
The Fermi Gamma-ray Burst Monitor (GBM) triggers on-board in response to ∼40 short gamma-ray bursts (SGRBs) per year; however, their large localization regions have made the search for optical counterparts a challenging endeavour. We have developed and executed an extensive program with the wide field of view of the Zwicky Transient Facility (ZTF) camera, mounted on the Palomar 48 inch Oschin telescope (P48), to perform target-of-opportunity (ToO) observations on 10 Fermi-GBM SGRBs during 2018 and 2020–2021. Bridging the large sky areas with small field-of-view optical telescopes in order to track the evolution of potential candidates, we look for the elusive SGRB afterglows and kilonovae (KNe) associated with these high-energy events. No counterpart has yet been found, even though more than 10 ground-based telescopes, part of the Global Relay of Observatories Watching Transients Happen (GROWTH) network, have taken part in these efforts. The candidate selection procedure and the follow-up strategy have shown that ZTF is an efficient instrument for searching for poorly localized SGRBs, retrieving a reasonable number of candidates to follow up and showing promising capabilities as the community approaches the multi-messenger era. Based on the median limiting magnitude of ZTF, our searches would have been able to retrieve a GW170817-like event up to ∼200 Mpc and SGRB afterglows to z = 0.16 or 0.4, depending on the assumed underlying energy model. Future ToOs will expand the horizon to z = 0.2 and 0.7, respectively.

Published: June 2022

During the course of a study on the biodiversity of endophytes from Cameroon, a fungal strain was isolated. A multigene phylogenetic inference using five DNA loci revealed that this strain represents an undescribed species of Diaporthe, which is introduced here as D. breyniae. Investigation into the chemistry of this fungus led to the isolation of two previously undescribed secondary metabolites for which the trivial names fusaristatins G (7) and H (8) are proposed, together with eleven known compounds. The structures of all of the metabolites were established by using one-dimensional (1D) and two-dimensional (2D) Nuclear Magnetic Resonance (NMR) spectroscopic data in combination with High-Resolution ElectroSpray Ionization Mass Spectrometry (HR-ESIMS) data. The absolute configuration of phomopchalasin N (4), which was reported for the first time concurrently to the present publication, was determined by analysis of its Rotating frame Overhauser Effect SpectroscopY (ROESY) spectrum and by comparison of its Electronic Circular Dichroism (ECD) spectrum with that of related compounds. A selection of the isolated secondary metabolites were tested for antimicrobial and cytotoxic activities, and compounds 4 and 7 showed weak antifungal and antibacterial activity. On the other hand, compound 4 showed moderate cytotoxic activity against all tested cancer cell lines with IC50 values in the range of 5.8–45.9 µM. The latter was found to be less toxic than the other isolated cytochalasins (1–3) and gave hints in regards to the structure-activity relationship (SAR) of the studied cytochalasins. Fusaristatin H (8) also exhibited weak cytotoxicity against KB3.1 cell lines with an IC50 value of 30.3 µM.

Published: June 2022

Abstract
Allegheny woodrats Neotoma magister are an imperiled small mammal species most associated with emergent rock habitats in the central Appalachian Mountains and the Ohio River Valley. The monitoring of populations and their spatiotemporal distributions typically has relied on labor-intensive livetrapping. The use of remote-detecting cameras holds promise for being an equally or more effective method to determine species presence, although trap-based captures permit the estimation of other parameters (e.g., survival, population size, site fidelity). In 2017, 2018, and 2020 we compared standard livetrapping with paired cameras for determining site occupancy of Allegheny woodrats in the central Appalachian Mountains of western Virginia. We further examined the influence of baited vs. unbaited cameras at several sites of confirmed occupancy in 2019. We observed that the detection probability using cameras was approximately 1.7 times that of live traps. Also, detection probability at baited camera traps was 1.3–2.0 times that of unbaited camera traps. Estimates of occupancy ranged from 0.44 to 0.49. Our findings suggest that the use of baited remote-detecting cameras provides a more effective method than livetrapping for detecting Allegheny woodrats. Our study provides a framework for the development of a large-scale, long-term monitoring protocol of Allegheny woodrats with the goals of identifying changes in the distribution of the species and quantifying local extinction and colonization rates at emergent rock outcrops and caves throughout the species' known distribution.

Published: June 2022

Background: Previous studies have found that indications for lumbar punctures (LPs) are managed differently, which raises the question of whether all LPs performed are clinically necessary. This study aimed to determine whether unnecessary (clinically not indicated) LPs were being performed at a district hospital in the Free State, South Africa.Method: This was a retrospective descriptive study. A list from the National Health Laboratory Service (NHLS) was used to identify all patients on whom an LP was performed in the adult emergency department of National District Hospital (NDH) in Bloemfontein, from 1 January 2018 to 30 June 2018. Data were captured on a data sheet and included demographic information, clinical signs and symptoms the patients presented with and the cerebrospinal fluid results.Results: A total of 364 patients fit the inclusion criteria. Of these patients, 97 files (26.6%) could not be found, patient gender and LP results could be retrieved from the NHLS barcodes. After reviewing the presenting symptoms and signs captured on the 267 files, the primary researcher considered 150 (56.4%) of the LPs performed to have been carried out unnecessarily. From the total population of 364 patients, 246 (67.6%) of the LP results were normal. Only 118 (32.4%) of the LPs performed showed some form of central nervous system pathology. Of the 150 LPs assessed to have been unnecessarily performed, 124 (84.0%) were normal.Conclusion: This retrospective review indicates that a high percentage of LPs that were clinically not indicated were performed at NDH during the study period.

Background: Human papillomavirus infection, a causative agent of cervical cancer, is of great concern, more so in populations with high HIV prevalence, such as South Africa.Aim: This review aimed to examine the prevalence and distribution of selected cervical human papillomavirus (HPV) types in HIV infected and HIV uninfected women in South Africa.Methods: PubMed and Web of Science databases were searched using key words. For data integrity, data was assessed by two authors independently. The study inclusion criteria comprised records on cervical HPV, HPV genotyping and HPV type distribution among South African women. Statistical analysis was performed using Social Science Statistics.Results: Sixty-nine articles met the inclusion criteria for analysis. Data on cervical HPV prevalence and type distribution was available only for five of the nine provinces of South Africa. Only 4/69 studies used sequencing as an approach to identify HPV types. In a general population, HPV type 16 was the most frequent (8.80%), followed by types 35 (4.86%), 18 (4.14%), 58 and 52 with the frequency of 3.65% and 3.62%, respectively. Furthermore, the least frequent type was HPV 70 (0.74%). Both HIV infected and HIV uninfected populations had a higher prevalence of high-risk human papillomavirus (hrHPV) types 16, 18 and 35 than other HPV types; while HPV types 6, 11 and 70 were the least frequent types from these populations. Lastly, HPV 16 was the most predominant type among women with normal (2.03%) and abnormal cervical cytology (6.60%).Conclusion: Expanding on HPV genotyping will improve the knowledge in patterns of HPV type distribution in South Africa that will further help in decision making to improve current diagnostics, and future vaccine development and assessment.
