Insect vector sampling was conducted in rainfed and irrigated rice fields every two weeks using a sweep net and a D-Vac (vacuum trap). From the samples obtained in the different rice-growing sites, the dominant structure of insect vectors of rice yellow mottle as well as their natural enemies was analyzed according to the phenology of rice. It appears from the inventory of insects in irrigated rice (Maga, Yagoua) and rainfed rice (Maroua) that this crop harbors many vectors of the rice yellow mottle virus. In the different rice-growing sites, we have numbers of vector insect individuals captured of 267, 286 and 385 respectively in Maroua (rainfed rice), Maga and Yagoua (irrigated rice). The vector insects captured are distributed as follows, eight species of vector insects in irrigated rice in Maga belonging to five families divided into three orders: Chnootriba similis (Coleoptera: Coccinellidae), Chaetocnema pulla (Coleoptera: Chrysomelidae), Locris rubra ( Hemiptera: Cicadellidae), Nephotettix nigropictus (Hemiptera: Cicadellidae), Sogatella furcifera (Hemiptera: Delphacidae), Cofana spectra (Hemiptera: Cicadellidae), Niparvata lugens (Hemiptera: Delphacidae) and Diopsis thoracica (Diptera: Diopsidae). In irrigated rice in Yagoua, eleven species of vector insects belonging to seven families divided into three orders were collected: Chnootriba similis (Coleoptera: Coccinellidae), Chaetocnema pulla (Coleoptera: Chrysomelidae), Locris rubra (Hemiptera: Cicadellidae), Nephotettix nigropictus (Hemiptera: Cicadellidae), Sogatella furcifera (Hemiptera: Delphacidae), Cofana spectra (Hemiptera: Cicadellidae), Recilia dorsalis (Hemiptera: Cicadellidae), Niparvata lugens (Hemiptera: Delphacidae), Leptocorisa oratorius (Hemiptera: Alydidae), Diploxys spp. (Hemiptera: Pentatomidae) and Diopsis thoracica (Diptera: Diopsidae). As for rainfed rice in Maroua, thirteen vector insect species belonging to seven families and three orders were collected: Chnootriba similis (Coleoptera: Coccinellidae), Chaetocnema pulla (Coleoptera: Chrysomelidae), Trichispa sericea (Coleoptera: Chrysomelidae), Locris rubra (Hemiptera: Cicadellidae), Nephotettix nigropictus (Hemiptera: Cicadellidae), Sogatella furcifera (Hemiptera: Delphacidae), Cofana spectra (Hemiptera: Cicadellidae), Recilia dorsalis (Hemiptera: Cicadellidae), Niparvata lugens (Hemiptera: Delphacidae) and Diopsis thoracica (Diptera: Diopsidae). These species proved to be particularly important by the size of their populations at the tillering stage of rice.

The study analyzed 32 articles and showed that the main impacts of MSDs were pain (56.5%), self-medication (17.4%), reduced quality of work and working hours (17.4%), absenteeism and early retirement (13.0%). Prevention was based on the practice of good ergonomics (73.3%), the use of magnifying glasses (33.3%) and the practice of physical exercise after work (20%).

Data available for this study were obtained from three wells (A11, A22 and A33). They were analyzed using Microsoft Excel after spurious values were removed. Two techniques (John Fuller and Plumb Bradford) were used to determine static young's modulus but only one is reported because after statistical analysis on both, the one reported was adequate for accurate outcomes although both approaches have low variance. The results indicates that the highest values of static and dynamic young's modulus are 2.05 x 1025N/m2 and 1.93 x 1010N/m2 respectively. The lowest values are 1.1 x 1024N/m2 and 8.5 x 109N/m2 respectively for well A11. The average values are 1.024 x 1025N/m2 and 5.25 x 1023N/m2 for this well.

The study employed the MPC with an electronic portal imaging device (EPID) to carry out geometric checks and verify the radiation isocenter. The isocenter size was assessed using the MultiMet cube and the MPC-enhanced couch module for SRS/SBRT pretreatment QA. Methods: The isocenter size of the MPC-enhanced couch module was compared to the WL measurements of the MultiMet cube. Measurements were taken at various gantry, collimator, and couch angles over a period of one month. The data from the cube were evaluated using PIPSRO and MultiMet (MMWL), including the offset targets. Various statistical tests were performed to evaluate the agreement, normality, separability, sensitivity, and specificity between the two methods. Results: The results showed isocenter sizes of 0.273 ± 0.065 mm, 0.293 ± 0.010 mm, and 0.209 ± 0.070 mm for PIPSPRO, MPC, and MMWL, respectively. The average bias was -0.0639 ± 0.1061 mm between MMWL and PIPSPRO, -0.0837 ± 0.0688 mm between MMWL and MPC, and 0.0198 ± 0.0696 mm between MPC and PIPSPRO. A Shapiro-Wilk test revealed no significant departure from normality for all tests and showed satisfactory discrimination through the area under the curve (AUC). A paired t-test analysis revealed a statistically significant difference between the mean isocenter size of the MPC and WL (MMPWL: t = 5.654, df = 29, p < 0.001; PIPSPRO: t = -1.483, DF = 29, p = 0.1488), and there was no significant difference within the WL test (t = 3.008, DF = 29, p = 0.0054). Conclusion: Despite the statistical test results, there was agreement between the MPC and WL radiation isocenter size that was within the requirement of the AAPM TG 142 tolerance (±1.0 mm).

Abstract should be informative, self-explanatory and easy to understand. Plant parts have continued to attract attention in the global search for the treatment of many diseases affecting humans. Dennetia tripetala (mmimi) is a well-known spicy indigenous forest fruit from the family annonacea and has been found to contain lots of minerals, vitamins, alkaloids and trace elements which are of medicinal importance. This study investigated the effect of topical ripe and unripe Dennetia tripetala seed extracts on the intraocular pressure of albino Wistar rats. Fifteen healthy male albino Wistar rats were used for the study. The rats were randomly divided into 3 groups (A, B, C), each group consisting of 5 rats. Group A rats were treated with one drop of ripe seed extract in their right eye and one drop of Timolol eye drop in their left eye. Group B rats received one drop of unripe seed extract in their right eye and one drop of Timolol eye drop in their left eye. Group C rats served as control (received one drop of water in OD). The I0P of each rat was measured pre and post instillation of one drop volume of the solutions at 30 mins interval for 120 minutes. The findings showed peak reduction of IOP after 60 mins (6.02 mmHg, representing 31.2 % reduction) of instillation one drop volume of ripe D. tripetala seed extract and reverted towards baseline (19.16 mmhg). The peak effect of ripe D. tripetala was found to be statistically significant (P =4.558). Unlike ripe D. tripetala seed extract, the unripe extract induced consistent IOP reduction till 120 minutes (5 % after 30 minutes, 16.5 % after 60minutes and 17.9 % after 120 minutes) from the baseline (18.84 mmHg). The reduction in IOP after 60 minutes (P = .4145) and 120 minutes was statistically significant (P= 2.5448). When compared with Timolol, Timolol produced steady and highest IOP reduction (15 %, 23.5 %, and 33.3 % from the baseline) 30 minutes, 60 minutes and 120 minutes post instillation respectively.
