Effects of strain, perch and nesting area inclusion or exclusion on performance, egg quality traits, and welfare in laying hens housed in enriched cage system
(eJournals, 2025-04-19) Amiri, A. N.; Şekeroğlu, A.; Tainika, Brian; Akyol, A; Şentürk, Y. E.; Duman, M.; Abacı, S. H.; Gür, F. M.
This study examined the impacts of perch and nesting area inclusion or exclusion on performance, egg quality, and welfare of two laying hen strains. In addition, the study emphasized the effect of hen age on egg quality traits, body region temperatures, and feather score. Lohmann brown (LB) and Lohmann LSL Classic (LW) strains were distributed to enriched cage units; PNO (without perch), PYES (with perch), or NNO (without nesting area), and NYES (with nesting area) at 20 weeks of age. It was identified that LB hens were heavier and had a higher comb, breast region, and footpad surface temperature than LW hens (p<0.01). Hens reared in PNO cages were heavier at 50% egg production than those reared in PYES cages (p<0.05). However, eggs with meat and blood spots in albumen were higher in PYES cages than in PNO cages (p<0.05). Additionally, hens reared in PYES cages had a higher footpad surface temperature than those in PNO cages. Hens reared in NNO cages reached 50% egg production earlier, had a higher comb and rectal temperature, and better feather scores compared to those reared in NYES cages (p<0.05; p<0.01). Eggs with a darker yolk color were obtained from NYES cages than from NNO cages (p<0.05). Furthermore, the effect of nesting area on tonic immobility (TI) approached a significant level (p=0.054), with a shorter duration of TI for hens reared in NYES cages than those in NNO cages. Blood parameters including heterophil-to-lymphocyte ratio were similar between strains, and perch and nesting area treatments (p>0.05). Age effects were observed on average egg weight, and egg quality traits apart from shape index, meat-blood spots in the yolk, feather score and body region temperatures (p<0.01), and egg-laying time impacted average egg weight (p<0.01). The study suggests no substantial evidence that the exclusion of a perch or nesting area in the enriched cages compromises performance and welfare measures in hens. In addition, relatively small differences were observed between the genotypes.
An insight into anthropogenic tourism potential of West Nile Sub-Region for livelihood improvement
(International Journal of Engineering Development and Research, 2025-04-30) Acadribo, Ofuti Charles
Tourism has become a favored development strategy for improving the livelihood of local communities by providing employment opportunities, market for local products, improving infrastructure, providing investment opportunities and so on. The study intended to understand the anthropogenic tourism potential of West Nile Sub-Region and create awareness so that it can be harnessed to promote tourism growth for livelihood improvement opportunity of people in west Nile sub-region. The study adopted qualitative approach research design to investigate the phenomenon. Primary data was collected by observation, focus group discussion and interview of key informants; and secondary data was collected by literature review. The findings indicate that West Nile Sub Region is extolled with abundant anthropogenic tourism potential that are under exploited. Most of the attractions lack basic facilities and services for visitor use, there is limited awareness about the potential, the available services and facilities are inadequate and in sorrow state, the accessibility to some of the sites are poor, there is limited capital for the improvement of the sites. The study recommends need for increased awareness, more investment in facilities and services to tap the potential, improvement of accessibility to some of the sites, more attention to be given by the government to the sector in budget.

Tourism has become a silver bullet in rekindling livelihood improvement of the local communities by providing employment opportunities, market for local products, improved infrastructure, investment opportunities and so on. The study intended to understand the natural tourism potential of West Nile Sub-Region and create awareness so that it can be harnessed to promote tourism growth for livelihood improvement opportunity of people in west Nile region. The study adopted qualitative approach research design due to the nature of the investigation. Primary data was collected by observation, focus group discussion and interview of key informants; and secondary data was collected by literature review. The findings indicate that West Nile Sub Region is endowed with abundant natural tourism potential that is under exploited. Most of the attractions lack basic facilities and services for visitor use, there is limited awareness about the potential, the available services and facilities are inadequate and in sorrow state, the accessibility to some of the sites are poor, there is limited capital for the improvement of the sites. The study recommends increased awareness, more investment in facilities and services to tap the potential, accessibility to some of the sites be improved, and more attention be given by the government to the sector in budget.
PLC based speed control in a color sorting system: A design and simulation perspective
(Journal of Engineering, Technology and Applied Science, 2025-04-25) Kalyankolo, Umaru; Munguleni, Marlon; Nansukusa, Yudaya; Asikuru, Salaama; Nafuna, Ritah; Kalyankolo, Zaina
For simulation purposes in Factory IO and TIA Portal, the research is tailored to emulate industrial sorting operations. In numerous industrial scenarios, sorting operations play a crucial role, with objects segregated based on various criteria such as dimensions, colors, weight, and material composition. For instance, within Thermal Power Stations, electromagnetic sorting techniques are employed to separate ferromagnetic materials from coal. This research specifically focuses on sorting goods based on color, with adjustable speed parameters to match production rates. The system is equipped with a digital display screen, providing real-time feedback on the count of sorted objects, and receives an analog speed signal from the PLC for precise control. This research is divided into two primary components, i.e. Software and Simulation in Factory IO. The software aspect involves the implementation of ladder logic programming in TIA Portal, enabling systematic control of the entire research process based on the input data sequence, while the simulation in Factory IO is encompasses the virtual representation of conveyors for object transportation and RGB color vision sensors for color detection. The entry conveyor features two branches to load objects onto the respective conveyors, directed by the sorting logic implemented in TIA Portal.
Effect of knowledge of sulfadoxine-pyrimethamine (SP) as prophylaxis for malaria on its uptake for intermittent preventive treatment of malaria in pregnancy (IPTp): Application of inverse probability weighted regression adjustment (IPWRA) technique
(PLOS, 2025-04-15) Natuhamya, Charles; Mwebesa, Edson; Tumwesigye, Nazarius Mbona
Introduction: Malaria still remains a global health issue. In response, the World Health Organisation has continuously recommended the use of Sulfadoxine-Pyrimethamine (SP) for Intermittent Preventive Treatment of Malaria in Pregnancy (IPTp) as a malaria preventive measure for the mother and fetus, which has been implemented by the Ugandan government. In collaboration with partners, the government has created awareness of using SP for IPTp (SP-IPTp) among women mainly through media. Studies have investigated the effect of a woman’s education attainment on SP-IPTp. However, the effect of knowledge of SP as prophylaxis for malaria on SP-IPTp has not been studied. Notably, education does not necessarily have an effect on knowledge of SP for malaria prevention, and knowledge of SP as prophylaxis may not result in its significant uptake for IPTp. The purpose of this study, therefore, was to ensure baseline covariate balance and determine the effect of knowledge of SP as preventive chemotherapy on its uptake for IPTp.
Methods: The study utilised the Ugandan Malaria Indicator Survey dataset of 2018–19. Women aged 15–49 years who indicated their uptake status of SP during their last pregnancy formed the sample of this study. The inverse Probability Weighted Regression Adjustment technique was applied to assess the study objective.
Results: The findings revealed a positive and significant effect of knowledge of SP as malaria prophylaxis on its uptake for IPTp (Average Treatment Effect of the Treated or ATET = 0.163; 95% CI = 0.138–0.188).
Conclusion: Ensuring covariate balance while applying IPWRA resulted in more precise estimates of treatment effects. Programmes and policies that create awareness of using SP as malaria prophylaxis may serve as effective interventions towards SP-IPTp in Uganda.
