Distribution and relative abundance of pig breeds in South-Western Agro-ecological Zone, Uganda: Status of locally adapted pigs
(Status of locally adapted pigs, 2023)A cross-sectional study was conducted in five districts in South Western Agro-Ecological Zone (SWAEZ), Uganda, to map pig breed distribution and determine their abundance and population structure. Purposive and snowball ... -
Design and Simulation of a Physician-Based Fuzzy System for Ventilator Adjustments in ARDS Patients to Ensure Lung Protection
(Advances in Fuzzy Systems, 2023)The acute respiratory distress syndrome patients largely need a mechanical ventilator intervention. There are procedures that have been developed to guide the physicians during the ventilation of the patient. Berlin ... -
Effect of problem-based learning on Ugandan secondary school physics classroom practices: an observational study
(F1000Research, 2023)Background: Regular class observations are common ways of monitoring what happens inside classrooms during the teaching and learning processes. From the start of 2020, the Ugandan Education System introduced a new curriculum ... -
Teacher Efforts Towards the Development of Students’ Mathematical Reasoning Skills
(2022)Research shows that enhanced mathematical reasoning leads to increased conceptual understanding and application of mathematical knowledge to various practical situations. However, the identification of classroom practices ... -
Relationship between active learning heuristic problem-solving approach and students’ attitude towards mathematics
(Eurasia Journal of Mathematics, Science and Technology Education, 2023)The study explored the direct relationship between active learning heuristic problem-solving approach and students’ attitude towards mathematics, using linear programming (LP) word tasks. Two instruments were used for data ... -
Adjusting to and thriving in a new school: Role of students’ expectations, educational attitudes, and resilience during secondary school transition
(International Journal of School & Educational Psychology, 2023)For some students, the transition from primary to secondary school is a difficult and stressful event that can have potential negative effects on their psychological wellbeing, social adaptability, and academic achievement. ... -
Mapping of the Ionospheric Total Electron Content over the East African Low–Latitude Region
(Advances in Space Research, 2023)Ionospheric behaviour is often monitored using total electron content (TEC) measurements from Global Navigation Satellite System (GNSS) receivers. However, the GNSS receivers are sparse over the East African low-latitude ... -
Spatio-temporal Variations and Potential Health Risks of Heavy Metals in Water from River Manafwa, Uganda
(Letters in Applied NanoBioScience, 2022)The epicenter of flash flood inundations and landslides in Uganda have been areas around Mt. Elgon. By implication, it has led into loss of lives, food and water insecurity. This study assessed the seasonal variations in ... -
In vitro anthelmintic activity of Leonotis nepetifolia ethanolic and aqueous leaf extracts on Fasciola gigantica
(Journal of Veterinary Medicine and Animal Health, 2022)Fasciolosis is a major problem to livestock production and is considered an emerging health hazard to humans and other animals. An increase in the prevalence of anthelmintic-resistant helminth strains, drug residues in ... -
The spectacular cluster chain Abell 781 as observed with LOFAR, GMRT, and XMM-Newton
(Astronomy & Astrophysics, 2019)Context. A number of merging galaxy clusters show the presence of large-scale radio emission associated with the intra-cluster medium (ICM). These synchrotron sources are generally classified as radio haloes and radio ... -
The LOFAR Two-metre Sky Survey
(Astronomy & Astrophysics, 2019)The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120–168MHz survey of the entire northern sky for which observations are now 20% complete. We present our first full-quality public data release. ... -
Study of Chemically Peculiar Stars-III: High-resolution Spectroscopy and K2 Photometry of New Variables in the Region of M44
(Sub-Saharan Africa Astronomy Summer School, 2022)We aim to carry out a study on the photometric and spectroscopic variabilities of four stars monitored in the Nainital- Cape survey. We analysed the photometric variability of the target stars, HD73135,BD+19° 2045, BD+19° ... -
Study of chemically peculiar stars –I. High-resolution spectroscopy and K2 photometry of Am stars in the region of M44
(Monthly Notices of the Royal Astronomical Society, 2022)We present a study based on the high-resolution spectroscopy and K2 space photometry of five chemically peculiar stars in the region of the open cluster M44. The analysis of the high-precision photometric K2 data reveals ... -
Starspots and Rotation Velocities of Normal A- And Am- Stars
(Stars and their Variability Observed from Space, 2020)Using the \hump and spike" features, we computed the rotation frequencies and amplitudes. The corresponding equatorial rotational velocity (Vrot) and spot size were estimated. On _tting the auto-correlation functions of ... -
Probing Accretion Disk Winds in AGN
(arXiv preprint arXiv, 2014)The Broad Line Region of Active Galactic Nuclei is characterized by broad Balmer emission lines in their optical spectra. The broad Balmer emission lines are found to be asymmetric, some blue sided and others red sided in ... -
New mysteries and challenges from the Toothbrush relic: wideband observations from 550MHz to 8GHz
(Astronomy & Astrophysics, 2020)Context. Radio relics are di_use extended synchrotron sources that originate from shock fronts induced by galaxy cluster mergers. The particle acceleration mechanism at the shock fronts is still under debate. The galaxy ... -
