The aim of this study was to evaluate the effect of Lactobacillus acidophilus（LAC）, exogenous enzymes of ZAD（exogenous enzyme preparation） or their combination on feed conversion, and dressing of rabbits fed different treatments of sugarcane bagasse（SCB）. Five rations were allotted randomly to five groups of New-Zealand White（NZW） rabbits（n=10） with initial live body weight of（838±42.4） g and 5 weeks of age. Rabbits were fed on diets with different sources of fiber as follows,（i） a control diet composed of 100% berseem hay and 0% SCB,（ii） 50% berseem hay and 50% untreated SCB（USCB）,（iii） 50% berseem hay and 50% SCB treated with L. acidophilus（LAC）,（iv） 50% berseem hay and 50% SCB treated with ZAD（ZAD）, and（v） 50% berseem hay and 50% SCB treated with a combination of LAC＋ZAD（LZ）. Treatments of SCB with L. acidophilus, ZAD and LAC＋ZAD had the highest feed conversion ratio than both USCB and control. The dressing percentage of rabbits that fed the LAC and LZ diets was higher（P〈0.05） compared with that in the other groups. Performance index（PI） for LAC group was improved（P〈0.05） compared to that for the other groups; however, PI for USCB group was the lowest（P〈0.05）. It could be concluded that treating SCB with L. acidophilus, exogenous enzymes of ZAD or their combination improved feed conversion and performance with more positive effects with L. acidophilus than the other treatments.

The assessment of floristic composition and diversity is very important in forest management units. This study sets out to determine the species diversity and implications for biodiversity conservation in FmU 09-025 of the Campo ma’an National park, South Region of Cameroon. Due to human activities in the area, the study site was divided into two Blocks (A and B). The transect method was employed in data collection. A total 14 long transects were established parallel to each other in blocks at a distance of 3 km apart, 8 transects in Block A and 6 Transects in Block. In each transect, plots of 20 × 500 m were established at intervals of 500 m. Within each plot, all individual trees ≥ 10 cm were identified, measured, and recorded. The DBH of all trees were measured at 1.3 using the DBH meter tape. The height of trees was measured through estimation (average estimates of all field researchers). Results revealed a total of eight thousand one hundred and twenty four (8124) individual plants with DBH ≥ 10 cm in the entire study area. From this number, 5113 tree stems ≥ 10 cm were identified and measured in Block A. This belongs to 216 species in 47 families. In block B a total of and 5011 stems were identified and measured. This belongs to 239 species in 47 families. Fabaceae, Annonaceae, Euphorbiaceae and Rubiaceae were found to be the most dominant plant families in the study site. Erythrophleum ivorense, Lophira alata, Dialium bipindense, musanga cecropioides, Alstonia boonei, Pterocarpus soyauxii, Guibourtia ehie, Staudtia kamerunensis, Desbordesia glaucescens, Sacoglottis gabonensis were found to be the most dominant plant species. 41 species are of conservation concern according to the IUCN global Red List 2023 and IUCN local status. These species are considered species with high-priority for conservation. We have 6 endangered species, 11 near Threatened species, and 25 vulnerable species. There was no significant difference in species diversity in the two Blocks.

To understand the self sustained propagation of the plasma jet/bullet in air under atmospheric pressure, the ignition of the plasma jet/bullet, the plasma jet/bullet ignition point in the plasma pencil, the formation time and the formation criteria from a dielectric barrier configured plasma pencil were investigated in this study. The results were confirmed by comparing these results with the plasma jet ignition process in the plasma pencil without a dielectric barrier. electrical, optical, and imaging techniques were used to study the formation of the plasma jet from the ignition of discharge in a double dielectric barrier configured plasma pencil. The investigation results show that the plasma jet forms at the outlet of the plasma pencil as a donut shaped discharge front because of the electric field line along the outlet＇s surface. It is shown that the required time for the formation of the plasma jet changes with the input voltage of the discharge. The input power calculation for the gap discharge and for the whole system shows that 56% of the average input power is used by the first gap discharge. The estimated electron density inside the gap discharge is in the order of 1011 cm^-3. If helium is used as a feeding gas, a minimum 1.48× 10^-8 C charge is required per pulse in the gap discharge to generate a plasma jet.
