An Innovative Way in Education and Training for Sustainable Development through E-Universities for Sustainability in Kenya
Authors: Omariba Alice 
Published: December 2024

The importance of education for sustainable development has been anchored in various forms in training and education in both developed and developing countries and acknowledged decades ago. Consequently, by joining several international conventions countries across the world agreed to effectively integrate, and implement education for sustainable development (ESD). The rationale of this study is that ESD must be propagated worldwide in different strata of societies and especially in education and training in order to protect the environmental equilibrium of our planet to curb the negative impacts it is suffering from the present-day consumer habits and the intensification of industrial and agricultural production. It is evident that ESD must be effectively integrated into public education and training, especially at the University level and crucially developed if we really want to reduce the environmental burden caused by human activities. One possibility for this is to develop modern, interactive; ICT-based educational tools at the Universities which may grab the attention of digital-era students. The study adopted exploratory and descriptive research designs whereby the target population was University Lecturers; the study used Slovan’s formula for the sample size and both random sampling was used to sample 100 University lecturers and purposive sampling was used to select University lecturers in social media (WhatsApp forums). The findings of the study revealed that the establishment and promotion of E-universities for sustainability in Kenya offer a promising and innovative approach to addressing the challenges of education and training for sustainable development. Based on the findings, the study concluded that embracing digital technologies not only expands access to education but also enhances the quality of learning experiences, fosters global collaboration, and equips learners with the skills and knowledge necessary to contribute meaningfully to sustainable development initiatives whereby E-universities for sustainability in Kenya can be an innovative framework which Universities, lecturers and NGOs across borders will use to collaborate to build interactive e-learning courses for University students

Authors: Muñoz Brenda , De la Peña Astorga Gabriela , Guillermo Valencia Cecilia Antonieta 
Published: December 2024

A partir de la examinación de videoensayos sobre cine recolectados en YouTube, este artículo expone las características distintivas que adquiere este género audiovisual en dicha plataforma. Para el estudio se implementó un método mixto complementario que integró el análisis de contenido para revisar el impacto y la forma de la muestra de 54 clips y el análisis cualitativo para profundizar en la retórica verbal y audiovisual de las piezas. Los resultados sugieren que se trata de un producto audiovisual cuya forma se compone generalmente de imágenes de stock que ilustran lo enunciado verbalmente y que en general tiene un bajo impacto en la plataforma. No obstante, la relevancia de este género se encuentra en el registro que hace de formas del conocimiento –intuitivo, concreto y universal– objetivadas en imágenes, memes y gifs de reacción, entre otros recursos textuales.

Abstract
Direct imaging observations are biased toward wide-separation, massive companions that have degenerate formation histories. Although the majority of exoplanets are expected to form via core accretion, most directly imaged exoplanets have not been convincingly demonstrated to follow this formation pathway. We obtained new interferometric observations of the directly imaged giant planet AF Lep b with the VLTI/GRAVITY instrument. We present three epochs of ∼50 μas relative astrometry and the K-band spectrum of the planet for the first time at a resolution of R = 500. Using only these measurements, spanning less than 2 months, and the Hipparcos-Gaia Catalogue of Accelerations, we are able to significantly constrain the planet’s orbit; this bodes well for interferometric observations of planets discovered by Gaia DR4. Including all available measurements of the planet, we infer an effectively circular orbit (e < 0.02, 0.07, and 0.13 at 1σ, 2σ, and 3σ, respectively) in spin–orbit alignment with the host and measure a dynamical mass of M

= 3.75M
Jup ± 0.5M
Jup. Models of the spectrum of the planet show that it is metal-rich ([M/H] = 0.75 ± 0.25), with a C/O abundance encompassing the solar value. This ensemble of results shows that the planet is consistent with core accretion formation.

Abstract
Previous Hubble Space Telescope observations of the star-forming cluster NGC 346 in the Small Magellanic Cloud (SMC) revealed a large population of pre-main-sequence (PMS) candidates, characterized by Hα excess emission in their photometry. However, without access to spectroscopy, the nature of these objects remained unclear. Using the NIRSpec instrument on board JWST, we studied a sample of these stars, with masses in the range of ∼0.9−1.8 M
⊙, effective temperatures (T
eff) in the range of 4500−8000 K, and PMS ages between ∼0.1 and 30 Myr. Here, we present the first spectra of solar-mass PMS stars in the metal-poor SMC (Z = 1/8 Z
⊙) and discuss the physical properties of 10 representative sources with good signal-to-noise ratio. The observations indicate that even the oldest of these PMS candidates are still accreting gas with typical rates of ∼10−8
M
⊙ yr−1 for stars older than ∼10 Myr, confirming their PMS nature. The spectra also reveal near-infrared excess and molecular hydrogen excitation lines consistent with the presence of disks around these stars. These findings suggest that in a low-metallicity environment, circumstellar disks can live longer than previously thought.
Kicking Time Back in Black Hole Mergers: Ancestral Masses, Spins, Birth Recoils, and Hierarchical-formation Viability of GW190521

Published: December 2024

Abstract
A pair-instability supernova (PISN) prevents black hole (BH) formation from stellar collapse within the approximate mass range M ∈ [65, 130] M
⊙. However, such BHs may form hierarchically through merging ancestral BHs, whose properties determine those of the “child” one: mass, spin, and recoil velocity. Crucially, the child will leave its host environment if its birth recoil exceeds the corresponding escape velocity, preventing further mergers. We exploit relations between the final recoil and spin of quasi-circular BH mergers to obtain posterior probability distributions for the hypothetical ancestral masses, spins, and birth recoils of the component BHs of GW190521. To this, we present a Bayesian framework applicable to existing estimates for the components of BH merger observations. We consider both the quasi-circular (generically spinning) analysis performed by the LIGO–Virgo–KAGRA collaboration and the eccentric (aligned-spin) one performed by Romero-Shaw et al. We evaluate the probability p
2g
that the GW190521 components inferred by these analyses formed from the merger of stellar-origin BHs and were retained by their environment. For the primary component, which populates the PISN gap, such scenario is strongly suppressed if GW190521 happened in a globular cluster with p
2g
∼ 10−3 unless it was quasi circular and its ancestors had aligned spins, uncharacteristic of hierarchical formation channels, or small spins, which yields p
2g
≃ 10−2. If GW190521 was eccentric, we obtain p
2g
≃ 0.1 for any host other than an active galactic nucleus, and zero for a globular cluster. If GW190521 was quasi circular, a nuclear star cluster origin is possible with p
2g
∈ (∼0.4, ∼0.8).

Abstract
In magnetic reconnection, the ion bulk outflow speed and ion heating have been shown to be set by the available reconnecting magnetic energy, i.e., the energy stored in the reconnecting magnetic field (B

r
). However, recent simulations, observations, and theoretical works have shown that the released magnetic energy is inhibited by upstream ion plasma beta β

i
—the relative ion thermal pressure normalized to magnetic pressure based on the reconnecting field—for antiparallel magnetic field configurations. Using kinetic theory and hybrid particle-in-cell simulations, we investigate the effects of β

on guide field reconnection. While previous works have suggested that guide field reconnection is uninfluenced by β

These results apply to systems in which guide field reconnection is embedded in hot plasmas, such as reconnection at the boundary of eddies in fully developed turbulence like the solar wind or the magnetosheath as well as downstream of shocks such as the heliosheath or the mergers of galaxy clusters.
AstroSat View of the Neutron Star Low-mass X-Ray Binary GX 5-1
Authors: Shyam Prakash V. P. , Agrawal Vivek K. 
Published: December 2024

Abstract
We present the spectral and timing study of the bright neutron star low-mass X-ray binary GX 5-1 using AstroSat/Large Area X-ray Proportional Counter (LAXPC) and Soft X-ray Telescope observations conducted in 2018. During the observation, the source traces out the complete horizontal branch (HB) and normal branch (NB) of the Z-track in the hardness–intensity diagram (HID). Understanding the spectral and temporal evolution of the source along the Z-track can probe the accretion process in the vicinity of a neutron star. Spectral analysis was performed in the 0.7–20 keV energy range for different segments in the HID using a multitemperature disk blackbody with an average temperature, kT
in ∼ 0.47, and a thermal Comptonization model. It is found that the optical depth of the corona drops from ∼7.07 in HB to ∼2.61 in NB. The timing analysis using the LAXPC instrument indicates the presence of quasiperiodic oscillations in HB and NB of the Z-track. The observed QPO frequencies are similar to the characteristic frequencies of horizontal branch oscillations (HBOs) and normal branch oscillations (NBOs). The HBO frequency increases from ∼12 to 40 Hz toward the hard apex. NBOs are observed at ∼5 Hz. The timing studies conducted in soft and hard bands indicate the association of HBO and NBO origin with the nonthermal component. Further research could explore the implications of this relationship for understanding the dynamics of accretion onto neutron stars.
Lombardo alpino ˹bréncul, brén(s)ciol, brìnsc(en), brìnscet˺ ‘ginepro’: una geolinguistica d’altri tempi

Published: December 2024

Il tipo lessicale lombardo alpino ˹bréncul, brén(s)ciol, brìnsc(en), brìnscet˺ &c. ‘ginepro’ (fra Canton Ticino e Ossola) mostra una considerevole variazione diatopica, costituita da 57 geovarianti locali oltre a 30 confronti romanzi alpini e otto slavi. La ricostruzione basata sulla sola regolarità delle Leggi Fonetiche porta, attraverso l’unico sostrato locale indipendentemente fondato (il celtico), a ridurre tale panorama a 36 antecedenti, tutti — con una sola eccezione (e due casi adiafori) — analizzabili come formazioni (derivate o composte) su una medesima radice, √*bʱrĕn‑ ‘sporgere, angolo, spigolo, punta’ (incluse le due forme ampliate √*bʱrĕn‑k‑ e √*bʱrĕn‑g‑). Per contro, una ventina di paromofoni semanticamente in vario grado vicini richiedono di essere ricondotti ad altre quattordici radici, ciò che si configura come un residuo tuttora attingibile della variegata Wortschöpfung preistorica fra la fase indoeuropea regionale e il sostrato leponzio‑gallico immediatamente preromano, secondo quanto risulta dall’applicazione degli stessi protocolli d’uso abituale nel caso delle altre classi e lingue indoeuropee.

Introduction:
The mode of delivery in twin pregnancy is a challenging decision for an obstetrician as the outcome of the 2nd twin is significantly affected by that.

Materials and Methods:
The prospective comparative observational study was conducted for the time span of March 2021–August 2022 in a tertiary care hospital in East India. Forty-four pregnant women with twin pregnancy with gestation age >32 weeks who underwent vaginal delivery (VD) were compared with 44 pregnant with twin pregnancy who underwent cesarean section (CS). Maternal socioeconomic and obstetric parameters were noted, and the perinatal outcome of the 2nd twin was observed and compared between both elective CS and VD groups.

Results:
Perinatal outcome of 2nd twin through CS showed significantly better Apgar score at 1 min and at 5 min. Umbilical artery pH > 7.2 was found more in the CS group than in the VD group. Intertwin delivery interval of ≥10 min was found to be significantly associated with low Apgar score.

Conclusion:
The strict vigilance during follow-up of the patient in the antenatal period and proper assessment of maternal and fetal state during VD might improve the outcome of the 2nd twin to prevent unnecessary CS and its complications following it.

Background
Syndromic obesity is characterized by a specific set of associated clinical features, but the similarity between different obesity syndromes can make it hard to diagnose accurately. Prader-Willi syndrome (PWS) is the most common type of syndromic obesity. A variety of molecular and cytogenetic techniques may be needed for the diagnosis of obesity. Multiplex ligation-dependent probe amplification (MLPA) helps by allowing the study of multiple specific genetic regions at once. This makes it an effective screening tool for large groups of patients who may have deletions or duplications in specific genes.

Objective
We aim to establish a precise diagnostic scheme for early diagnosis that yields proper early intervention to prevent the development of morbid obesity and intellectual disability, which render a great burden on both health services and the families of the patients.

Materials and methods
Combined cytogenetic fluorescence in-situ hybridization and methylation studies using MLPA was conducted on 20 patients who were clinically suspected to have PWS.

Results and conclusion
We analyzed 20 suspected PWS cases descending from 18 unrelated families and 20 healthy controls matching age and sex, using MS-MLPA PWS/AS probemix (MRC-Holland) enables the identification of copy number variations or abnormal methylation patterns.
One patient (P18) had PW deletion, which was evident by the reduced copy number ratio, and uniparental disomy was evident in two unrelated patients (P2 and P12).
The results indicate that our study identified one typical PWS deletion and two uniparental disomy cases among three patients from distinct families, suggesting that atypical deletions are infrequent in this cohort. This research represents the first exploration of PWS in Egyptian patients using MLPA.

Published: December 2024

Abstract

Background:
In India, there is significant attrition in the cascade of care for tuberculosis (TB) in the public health sector. Pharmacy being the first point of contact for the majority holds considerable potential in reducing this attrition.

Objectives:
The objective of this study was to determine the willingness of pharmacists to screen and refer presumptive TB patients and understand challenges and enabling factors for the same.

Materials and Methods:
A sequential explanatory mixed-method study was conducted among pharmacies of Puducherry. Willingness to refer presumptive TB patients and collect sputum samples was summarized as proportions with 95% confidence interval. Log binomial regression was done to study the association of pharmacists’ characteristics with willingness to refer. In-depth interviews with pharmacists were transcribed; manual content analysis with hybrid coding was done.

Results:
Among the 202 pharmacists interviewed, 99.0% were willing to refer, 37.1% were willing to collect sputum samples, and 42.6% had ever referred a patient in the past. Patients’ lack of awareness, busy hours, and overuse of over-the-counter drugs hindered referral, while availability of quality diagnostic and treatment services, relationship with clients, and pharmacist’s knowledge facilitated referral.

Conclusion:
Willingness to refer patients for TB diagnosis was high among pharmacists. The national program should consider the engagement of pharmacists for improving screening and referral.
Anthropometric Indices as a Predictive Screening Tool for Hypertension among Young Indian Adults
Authors: Aruna R. , Santhanakrishnan Niveatha , Raj Jeneth Berlin 
Published: December 2024

Abstract

Background:
High blood pressure (BP) is increasing at an alarming rate in India and is the leading cause of cardiovascular disease. Increasing obesity is one of the risk factors for the increasing trend in hypertension among young adults.

Objectives:
This study aimed to assess the comparative abilities of anthropometric indices of general and central obesity in predicting hypertension among apparently healthy young adults.

Materials and Methods:
A cross-sectional study was conducted among 493 healthy young adults aged 18 and 25 years. Height, weight, waist, and hip circumference were measured, and anthropometric indices were calculated. BP was measured using an automated BP monitor. Statistical methods such as independent t-test, linear regression, and receiver operating characteristic (ROC) analysis were employed.

Results:
The prevalence of systolic and diastolic hypertension in males was 15.2% and 17.9%, whereas in females, it was 13% and 14.3%. All anthropometric indices positively correlated with systolic BP and diastolic BP, with the highest being waist circumference (WC). The area under ROC curves (AUC) of the anthropometric indices for predicting hypertension showed that WC had the largest AUCs for systolic and diastolic hypertension, respectively. In males and females, WC had the highest sensitivities of 85.4% and 90.3% for systolic and 84.3% and 88.6% for diastolic hypertension.

Conclusion:
Anthropometric indices of central adiposity were more significant predictors of hypertension.
