ABSTRACT
The aim of CT imaging is to detect treatable lesions before secondary neurological damage occurs. CT plays a primary role in the setting of head trauma, allowing accurate detection of lesions requiring immediate neurosurgical treatment. CT is also accurate in detecting secondary injuries and is therefore essential in follow-up. This review discusses the main characteristics of primary and secondary brain injuries.

ABSTRACT
In vitro and in vivo studies were carried out to evaluate aqueous extracts from Allium sativum L. (Garlic) against Ralstonia solanacearum isolated from an infected tomato plant. Four concentrations, (10, 20, 30 and 40%) of aqueous garlic extracts were prepared using cool (35o C) and hot (70o C) water. Evaluation of the extract concentrations against the pathogen was done using the agar well diffusion method in a nutrient agar medium. Incubation was for 48 hours at 35o C. In the in vivo studies, the most effective concentrations of garlic extracts were used as seed priming agents on tomato seeds sown in R. solanacearum infested soil in plastic pots. All data collected were subjected to statistical analysis using Minitab software (Version 17), while means were separated using Tukey’s test. Results showed that cool garlic extracts at 40% had a 30.63 mm zone of inhibition against the pathogen. This was significantly higher than 10.90 mm recorded by 10% of both cool and hot extracts. Hot extract, 40%, treated seeds recorded the highest number of leaves (21.75), had no incidence of bacterial wilt, gave the best plant height (45.75 cm) and fruit weight (327.1 g), surpassed only by the standard check. There is a need for more work to be done to developing an antibacterial agent from garlic for the management of bacterial wilt disease of tomatoes.

ABSTRACT
This paper tries to find out the factors that explained economic growth in Nigeria in the last three decades. It explores how variables such as foreign direct investment, physical capital, export, saving, natural resources, financial development, population, government size, and foreign exchange influence economic growth in Nigeria. It uses data from 1989 to 2019 and the dynamic econometrics modelling techniques of autoregressive distributed lag (ARDL) and generalized method of moments (GMM) models to analyze the data. The findings show that physical capital, agriculture, saving, population growth and government size have positive effects on economic growth in Nigeria during the study period. The paper recommends increase in physical capital build up through various types of infrastructural investments, more development of the abundant potentials in the agricultural sector and increase in national saving through government encouragements and favorable policies. These shall be anchored by good macroeconomic management of the nation’s economy.

ABSTRACT
Evaluation of management practices of rural chickens in Tonj County, Warrap State, South Sudan is imperative as chickens constitute a source of animal protein and income. Data were gathered using questionnaire, direct interviews and observations from 50 households randomly selected from various villages/Bomas. The study revealed more household aged 30-50 years old, abundant women and high illiteracy level. Total average flock size per household was 25.6 chickens with most households keeping hens and chicks. Diseases and predation were causes for annual flock losses. Households mostly depend on scavenging system of rearing chickens. Houses of different designs and materials were constructed. High fertility and hatchability rates among chickens were observed. Households accrued 2,050,000 SSP (11,388.9 USD) from the sales of live chickens to help mitigate poverty, food and nutritional insecurity. Tapping the households’ attitudes and practices was recommended. Further study on chicken marketing management system is needed to enhance socio-economic development.

ABSTRACT
This study aims to determine the health level of the bank owned by the Lampung regional government of PT BPD Lampung for the period 2016 to 2019. The method used RGEC (Risk Profile, Good Corporate Governance, Earning, Capital) method. The results are healthy bank for PT Bank Lampung was Risk profile for Non Performing Loan (NPL) of 2019, 2018, 2017 and 2016 were very healthy, but for Loan to Deposit Ratio (LDR) of 2019 was healthy, 2018 and 2017 are quite healthy, 2016 was Less healthy. The Good Corporate Governance (GCG) of 2016, 2017, 2018 and 2019 was healthy. The earning bank healthy rating for Return on Asset (ROA) of 2016, 2017, 2018 and 2019 were very healthy, Net Interest Margin (NIM) of 2016, 2017, 2018 and 2019 were very healthy, and Operating Expenses to Operating Income (BOPO) )) of 2016, 2017, 2018 and 2019 were very healthy. The capital bank healthy rating of Capital Adequacy Ratio (CAR) of 2016, 2107, 2018 and 2019 were very healthy, the composite rating period of 2016 until 2019 was very healthy.

ABSTRACT
To evaluate the impact of human-induced disturbances on the biodiversity of the Bafut-Ngemba Forest Reserve, data on tree species, the identity and number of plants per species were collected from an undisturbed and a disturbed forest fragment using transects. A total of 78 individual trees of 20 species belonging to 17 families were recorded. The undisturbed site had 72.22% of the tree species and 70.51% of individual trees. The most common tree species were Eucalyptus grandis, Pinus wallichiana, and Persea americana while Rosaceae and Fabaceae were the dominant families. Eucalyptus grandis, which was the most abundant tree species with a relative density of 12.82%, was found exclusively in the disturbed fragment. Fifty-five percent (55%) of the tree species were categorized as either rare (1.00 ≤ Relative Density ≤ 2.99) or occasional (3.00 ≤ Relative Density ≤ 3.99). Margalef species richness index was 9.04 for the undisturbed site and 5.74 for the disturbed. While Shannon-Wiener diversity index was 2.65 and 1.13 for the respective sites, Sørensen’s similarity coefficient indicates that the two fragments were only 20.69 % similar. It is hoped that the findings will prompt forest managers and decision makers to put in place mitigating measures and safeguards against a decline in flora of the ecosystem under imminent challenges associated with an expected increase in human population.

ABSTRACT
Massive expansion of urban areas leads to land use/land cover (LULC) changes which significantly alter the hydrology of river basins. Yet, systematic and logical information on the spatio-temporal dynamics of urban LULC changes of African river basins, Kenya inclusive is scanty. This study established the spatio-temporal dynamics in urban LULC change in Nanyuki and Likii sub-catchments in the Upper Ewaso Ng’iro North River Basin from 1985-2018. This was achieved mainly using Landsat satellite images for 1985, 1995, 2008 and 2018, topographic, Open Street and urban plan maps. A pixel based supervised classification using Maximum Likelihood Algorithm and post-classification comparisons were used in the analysis. The study established eleven LULC types, seven of which were urban and four non-urban. In 1985, urban LULC types occupied a relatively small portion of 869Ha (3.4%) but continuously expanded in all directions. Residential LULC registered the highest overall change of 2176.2Ha (8.5%). Overall annual rate of urban LULC change was established at 0.42% with period 1995-2008 having the highest annual rate of 0.98%. These findings can be incorporated in urban spatial planning and in the assessment of the effect of the continuous urban land expansion on the river basin hydrology.
