The Impacts of Public Libraries in Promoting Knowledge Society among Civil Servants in Nigeria
(LP2M Universitas Islam Negeri (UIN) Syarif Hidayatullah Jakarta, 2022-05-31) K. T. Omopupa
Public libraries serve as gateways to knowledge and culture by playing a fundamental role in society. The aim of this study is to examine the impacts of public libraries on the promotion of knowledge societies among civil servants in Oyo State, Nigeria. The total population was 570, and the sample size was 235 using a simple random sampling technique. The research design adopted was a descriptive survey. A questionnaire was used as an instrument for data collection, and a descriptive data analysis technique of frequency and the simple percentage was used. Findings revealed, firstly, that public libraries promote knowledge societies among civil servants through their collections, resources, and internet facilities to enhance the civil service culture. Secondly, public libraries have contributed significantly to improving and promoting knowledge societies as the civil servants make judicious use of the library facility to promote knowledge societies. Thirdly, public libraries have limitation that hindered the promotion of knowledge societies among civil servants; which are inadequate library materials, poor reading culture, inaccessibility to information resources, poor dissemination of information, and inadequate professional staff have. The recommendations of this study are the public libraries should provide more collections, adequate information resources tailored toward the promotion of knowledge societies, recruit professional staff and conduct regular training to improve their discharge of duties to meet the information needs of civil servants for the promotion of knowledge societies.

Quality attributes of biscuits fortified with baobab leaf powder
(African Society of Food Science and Technology (ASoFoST), 2018-08-02) Dauda, Adegbola; Olalere, Abosede; Abiodun, Olufunmilola
Biscuit is a nutritive snack eaten by everyone and often produced from unpalatable batter transformed into appetizing product through oven heat, and the major raw material is the wheat flour. The research work, however, was carried out to assess the effect of dried baobab leaf flour incorporated into biscuit production in the ratio 2% to 10%, while the control sample had no dry baobab leaf flour. The functional and proximate composition of the flour samples were determined, while for the biscuit samples, the proximate, colour, mineral, microbial and sensory properties were evaluated. The result of the flour samples showed the baobab leaf flour had higher values for water absorption capacity, oil absorption, bulk density and dispersibility when compared to that of the wheat flour. It was observed that the protein and ash contents of the biscuit samples increased with increasing quantities of baobab leaf flour, while the carbohydrate content decreased accordingly. Microbial and fungal growths were higher in the control than the treated samples, revealing the preservative potentials of baobab leaf. Also, there were significant differences at p>0.05 in all the sensory properties analysed. Sample B with 2% baobab leaf flour and 98% wheat flour had the best overall score.

histopathology of gills and livers of juvenile Clariasgariepinus(Burchell, 1822)exposed to aqueous extracts of Carica papaya dry seeds under laboratory conditions
(Library and Publications Committee, University of Ilorin., 2021-04-06) Abubakar, Musa
African Sharptooth, C.gariepinus (mean weight 11.81g±0.23g and mean length 9.8cm ± 0.2) were exposed to graded concentration (0, 150, and 180, 210 and 240mgL-1) of aqueous extract of C. papaya dry seeds in triplicates for 4 days. They were fed a 25% crude protein diet at 1% biomass half at 800 and 1600h. Experimental design was a completely randomized type. The control fish’s gill histology revealed normal histomorphology with intact blood vessels, gill slits and supporting cartilage apparent. Exposed fish showed degeneration of the gill filament, hypertrophy, hyperchondrial of the gill arch and lesion. Normal tubules, haematopoietic structures, and a portal triad with a dilated portal vein were found in the livers of control fish. The exposed fish livers showed vacoulation, steatosis, necrosis and degeneration of hepatocyte degeneration. The findings suggest that pathology of Clarias gariepinus’ gill and liver could be useful biomarker for assessing aqueous extract of Carica papaya dry seeds toxicosis.

Gill parasites associated with Claria sgariepinus in Sango Fish Farms, Ilorin, Kwara State,
(Library and Publications Committee, University of Ilorin., 2021-04-06) Abubakar, Musa
A study was carried out on gill parasites associated with Clarias gariepinus in Sango fish farm, in Ilorin, Kwara State. A total of Eighty-One (81) Clarias gariepinus were obtained from the fish farm in Ilorin. The fish were examined for gill parasites. Four different gill parasites were identified namely: Acanthocephala spp, Gyrodactylus spp, Procamallanus spp and Trichodina spp. Out of the Eighty-One (81) C. gariepinus examined, 23 (61.67%) were infected and were observed to harbour One Hundred and Two (102) gill parasites. Percentage of Infection was highest in fish ranging from 41.0 – 50.0 cm (100%) while fish ranging from 20.0 - 31.0 cm had the least percentage of infection (23.80%). Highest infections (100%) were observed among the fish specimens that weighed between 410.0 - 500.0g. Fewer parasites (10%) were observed among the fish specimen that weighed between 210.0- 300.0g. while fish specimen that weighed between 100.0 — 200.0 g had intermediate numbers of parasites (32.72%). Percentage and Index of infection (31.11% and 16.17) were more significant in males than in females (30.56% and 15.27) respectively. Statistical relationship between the fish farm and gill parasites infestation was highly significant. High statistical relationship was also observed between gill parasite infestation, sex and size of C. gariepinus. The study concluded that there were gill parasites in C. gariepinus species from Sango in Ilorin. The study recommends regular treatment of cultures Clarias gariepinus fish for maximum yield, aquaculture health and general well-being

Effect of sublethal concentration of sniper 1000EC on weight and length growth of Oreochromisniloticus obtained from Asa dam under laboratory conditions
(and Publications Committee, University of Ilorin, 2018-04-17) Abubakar, Idi-Ogede
The study investigated the effect of sublethal concentration of sniper 1000EC on the weight and length growth of Oreochromis niloticus obtained from Asa dam under laboratory conditions. Indiscriminate use of Sniper 1000EC by fishermen has become a serious problem in Northern region of Nigeria. Juveniles of Oreochromis niloticus (mean body weight 7.05± 1.02; mean standard length.9.60±0.38cm) were subjected to 5 sublethal treatment levels: 0.00mg/L is the control, 0.12, 0.15, 0.19 and 0.25mg/L. There was no significant difference between water quality parameters of the exposed and control groups. A 56 day exposure to sublethal concentrations of the toxicant led to a significant decrease (p<0.05) in specific and relative growth rate in the exposed fish species in comparison with their controls. Change in weight and length decreases with increasing sublethal concentrations of sniper 1000EC. It is concluded that depressive growth rate in the exposed fish species were consequences of exposure to the toxicant (sniper 1000EC).It is recommended that the use of Sniper 1000EC by local fishermen be banned to save the aquatic environment from destruction.
