In any democratic society, rule of law is a crucial tool to maintain good governance. Ethiopia is striving to build democracy and rule of law .To that effect; it has promulgated different laws and policies in the past decades. It has enacted its first federal constitution in 1995. The Federal Democratic Republic of Ethiopia (FDRE) constitution in its preamble clearly provides that maintaining rule of law is one of the basic goals that the Ethiopian Nation Nationalities and Peoples strive to pursue. Even if different factors (for example such as culture and level of development) explain democratic and rule of law based society, role of vibrant judiciary (judiciary that actively supervise public authorities) is paramount. Conventionally, judicial organ is one of the three organs of government to which the power of interpreting the law is given. In Ethiopia too, the judiciary is made the ultimate law interpreter thereby maintain rule of law and good governance. So as to perform such an act, the judiciary should exercise its inherent power of judicial review.

This paper looked at Nigerian Law Library management in the age of technology using selected management theories. Classical, behavioural and modern management theories provided guidelines for providing a modus operandi in Nigerian academic Law Library management. This study showed that technological age has shifted intensively into educational settings, and information centres have taken the path of innovation to meet up with the demands of technology. Management theories were critically looked at and it was found that classical management theories were no fit for management of organisations in a dynamic technology era. Issues inherent in Nigerian academic Law Libraries were found inimical to the trends of technology age. Behavioural and Modern management theories were recommended for managing academic law libraries through the technological age. Chaotic theory, systems theory and contingency Management theories are subsets of modern theories deemed fit for a paradigm shift of academic Law libraries. While McGregor’s “Y” theory was deemed fit for applying right motivation to Law Library workforce.

Cloud computing promises to significantly change the way we use computers and access and store our personal and busi-ness information. With these new computing and communica-tions paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the cloud provider. We propose a different approach for securing data in the cloud using offensive decoy technology. We monitor data access in the cloud and detect abnormal data access patterns. When unauthorized access is suspected and then verified using challenge questions, we launch a disinformation attack by returning large amounts of decoy information to the attacker. This protects against the misuse of the user’s real data. Experiments conducted in a local file setting provide evidence that this approach may provide unprecedented levels of user data security in a Cloud environment.

Fully developed laminar mixed convection of permeable couple stress fluid in a vertical channel has been investigated analytically in the presence of heat generation or absorption. Uniform wall temperatures with asymmetric and symmetric heating have been considered. An analytical solution has been developed by using perturbation technique. Results are depicted graphically on the flow for different values of couple stress parameter, porous parameter, mixed convection parameter and heat generation or absorption coefficient. The results show that the flow reversal occurs near the walls of the channel for sufficiently large value of the ratio of Grashof number and Reynolds number.

Ambient (outdoor) air pollution is now recognized as an important problem, both nationally and internationally. Air pollution is harming our health and that of our children and parents. The young and old are particularly vulnerable to the effects of air pollution. Air pollution causes many harmful effects, ranging from premature death, to headaches, coughing and asthma attacks. But it is easy to forget that we are contributing to the air pollution as we drive our vehicles, or potentially harmful pollutants spew out of the chimneys of huge factories, We think that pollutants simply blow away, but under some conditions they may be inhaled, minutes or hours later. That is we are careless about air pollution and its impact on health. The need of the hour is to ensure that our air is clean for us and for our future generations, we need to reduce emissions of pollutants into the air. Government bodies develop regional air plans and education programs aimed at reducing pollution, central government is developing vehicle emissions standards, national environmental standards and new fuel regulations to monitor and keep the air pollution under control and improve the quality of air.

The purpose of this study was to determine the morphological diversity of banana and plantain in the province of Maniema and to identify criteria for the choice of planting material, as well as the different uses of banana in the study area. To do this, a survey was carried out using the questionnaire established by Bioversity-CIALCA, on the morphological characterization of the different cultivars. These surveys identified 19 banana cultivars as follows: 4 French type plantains, 3 false horns, 2 true horns, 6 dessert bananas and 4 cooking plantains not belonging to the first three groups. The results also showed that dessert-type bananas are the most diversified in the study area (Maniema Province) with a proportion of 31% followed by French-type plantains with 27%. A small proportion of cooking plantains (7%) were recorded in this region. All these banana and plantain cultivars of the region have been described on the basis of previous knowledge, which allows to enrich the biodiversity knowledge of this crop in the Province of Maniema. Criteria for choosing planting material include flavor, taste, the amount of juice first and demand / price on the market for essential items (such as salt, soap, ...) and for sustainable production because they work for self-consumption. The main uses of banana in the region are food and the manufacture of indigenous alcohol.

This paper attempted to fit an appropriate probability density function to available crime data in Nigeria by using the Pearson System of Distribution Approach. Rising crime rates have necessitated the need to model adequately crime occurrences to enhance effective management and control. Aggregated dataset of crime rates from 1994 to 2003 were used to estimate the parameters of the selected density functions from the Pearson system and for the goodness of fit test. Results showed that the Four Parameter Gamma density function was the most suitable for the data under study. This study has revealed the potentials of probability density functions in crime prevention and control.

Suitable clinical learning environment results in appropriate learning outcomes in clinical area. The objective was to analyse the influence of clinical environment on clinical learning. Cross sectional research design was used. Study targeted 200 participants sampled purposively. Data was recorded in SPSS version 21.0 and analysed using t-test for means. Statistical significance was determined at p=0.01 the data was presented in form of tables. The study found that clinical placement (p=0.015), and length of clinical attachment (p=0.04) were predictors of clinical learning. The study recommends teaching facilities to establish appropriate schedule for clinical placements in order to enhance clinical learning.

In this paper, we consider a new method to improve the performance of TCP over wireless networks. The method employs NDG loss-predictor function to determine congestion losses from that of transmission loss. The sender window can adjust its size depending on the loss information. If the loss is due to congestion congestion control algorithm is invoked to decrease the flow rate. If the loss is due to wireless transmission, immediate-recovery algorithm is invoked to recover the losses caused by the sender TCP. To minimise the packet losses due to congestion, we use stability analysis over the system by applying a time-delay control theory. By constructing Hermit matrix, system analysis is made for asymptotic stability. Explicit conditions are derived for Pmax (RED controller) and ? (fNDG parameter) in terms of wireless network parameters. Using the characteristic equation of the Hermite matrix, convergence analysis of the instantaneous queue length at the bottleneck router is made. Convergence of the queue length to a given target value is analysed. This minimise the oscillatory behaviour of the RED router. An approximate solution of queue length is also derived. Our results provide better solutions for global stability and convergence conditions of the wireless system.
