Road safety problem draws significant attention in a developing country like Bangladesh where road accidents are extremely high. It is estimated by AAA that among eight national highways, over 14% fatal accidents occur on only Dhaka – Chittagong highway, a major transportation artery in Bangladesh. The study was intended to identify the accident- prone locations commonly termed as Hazardous Road Locations on Dhaka – Chittagong highway. The accident data were collected from the database of Accident Research Institute, Bangladesh University of Engineering & Technology, using the Microcomputer Accident Analysis Package Five (MAAP5) software. The Geographic Information System was used as a tool to identify the HRL on Dhaka – Chittagong highway. A total of 35 segments were identified as HRL on Dhaka – Chittagong Highway. This research work comprises the detail accident analysis of one segment on Dhaka – Chittagong Highway which is identified as the most hazardous among the 35 HRL.

The “Global Climate Change and Children’s Health” is a technical report and policy statement (1), that outlines the specific ways global climate change impacts child health, and calls on health practitioners to understand the threats, anticipate the impact on health, and advocate for strategies that will lessen the effects.A carbon footprint is defined as: The total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2). It is often understood as in the following examples: Each of the following activities adds 1 kg of CO2 to carbon footprint:- •Travel by public transportation (train or bus) a distance of 10 to 12 km •Drive by car a distance of 6 km (assuming 7.3 litres petrol per 100 km ) •Fly with a plane a distance of 2.2 km•Operate a computer for 32 hours (60 Watt consumption assumed) •Production of 5 plastic bags/ 2 plastic bottles/ one third of an American cheeseburger ( the production of each cheeseburger emits 3.1 kg of CO2!)

Effective utilization of bandwidth andstorage space is important in imaging applicationsincluding remote sensing. Remote sensingapplications use multi-sensory, multi-band, multiresolution images. Usually, remote sensingapplications uses image classification results fortheir analysis and decision making. In this paper wepropose a new JPEG based image compressionalgorithm based on filters. Proposed algorithmperformance is evaluated in relation to conventionalJPEG algorithm. In order to envisage the effect ofcompression on classification performance, MaximumLikelihood, Mahalanobis and Euclidean distanceclassifiers performance is evaluated with originalimage data, conventional JPEG compressed data andthe compressed image data with the proposedmethod. Experiments are carried out with manymulti-band images. Our experiments supports thatthe classification accuracies of compressed imagesare at par with original image data.

Seizures are the most noticeable clinical manifestations of epilepsy; measurement of the hippocampus on magnetic resonance (MR) images of the brain has been useful for the assessment of patients with seizures. Therefore this study aimed to diagnose subjects who had developed epilepsy by measuring the RT and LT hippocampus area and volume considering epilepsy duration, seizure frequency, EEG results, T2 signal intensity, treatment, and children ages as well as to correlate the MRI findings with EEG findings. This Study was conducted at Gezira University- MRI Diagnostic center –Khartoum –Sudan during the period from 2010up to2011using Siemens 0.5 Tesla MRI machine. A total of 29 Sudanese children of both genders with clinical history of generalized seizures, and 17 normal children who were selected as control group at different ages were involved in this study. Children with head injury or organic lesion found on MR images were excluded.

Background: Injuries from motorcycle accidents are a major contributor to mortality and morbidity in Nigeria. Injuries are varied amongst victim from bruises to severe head injuries. We therefore sought to determine the degree of severity of injuries sustained by motorcycle accident victims in our environment. Methodology: A prospective study of motorcycle accident victims including riders, passengers, and pedestrians was undertaken over a one year period from January 2012 to December 2012 at the trauma Centre of a tertiary hospital in Sokoto, North-West Nigeria. Information obtained from the trauma register included the age and sex of victims, use of protective helmet, and nature of collision, injury severity, determined by the injury severity scores and outcome. Results: A total of 803 victims of motorcycle accidents were seen over the 12 months period with majority of victims in the age range of 21-30 years representing 44.3%. Most of the accidents occurred in the months of October 13.8%, May 13.2%, June 11.7% and April 11.0 %. Fifty-five per cent of victims were the riders while passengers constituted 34.8%. The nature of accident was such that 43.6% of victims were as a result of motorcycle-motorcycle collision while 24.2% of victims were of lone motorcycle accidents. Victims from motorcycle-car collision were 21.9 %. Eighty-one per cent of victims had injury severity score (ISS) of 4 and below while the highest ISS of 29 was seen in one victim. Eighty four per cent of victims were treated and discharge while nine victims died. Twelve per cent of victims were admitted for further management while 3% signed and left against medical advice. Conclusion: The severity of injuries in motorcycle accidents victims though low, measures are however needed to reduce and regulate the use of motorcycle. This can be done through licensing, education and enforcement of use of helmet.

This research was conducted to examine the causes of poor academic performance by student nurses in the Bayelsa State School of Nursing in Nigeria, using the descriptive survey. The population consisted of 206 student nurses. As a result of their small size, they were all adopted for the study. However, only a total of 201 of the student nurses who completed their questionnaires participated in the study. A researcher-designed instrument named ‘Student Nurses’ Academic Performance Questionnaire’ (SNAPQ) was employed in generating data for the study. The instrument was validated and a reliability index of 0.87 was obtained. The instrument was analyzed using simple percentages and t-test statistics. Results showed that the five perceived causes of poor academic performance among student nurses included: giving the students too many assignments, parents’ inability to provide all the text books needed, student nurses lacking all their basic needs, lack of library and internet facilities and students’ inability to understand the science subjects. The ttest employed showed a statistically significant difference in students nurses’ perception of causes of poor academic performance on the basis of class level. The recommendations included provision of counselling services for the students and teachers, restructuring the nursing curriculum and reducing the number of assignments given to the students by their teachers, students’ formation of study groups, provisions of library and internet facilities, amongst others.

Wind tunnel is a simple but marvelous element of scientific research and expanding empire of application day by day. Wind tunnel has been used in racing cars, airplanes, weather patterns, skydiving simulations and for aerofoil testing in laboratories. In this study, a wind tunnel with isokinetic probes has been designed, fabricated and tested for sampling aerosol particles. The cross section of the wind tunnel is circular having six inch in diameter. The type of flow in the tunnel is open, uniform and the cross sectional area is constant throughout the tunnel. In this work, an atomizer generates polydisperse aerosols in a generation chamber and monodispersetest aerosols are produced by separating the polydisperse aerosols in an improved virtual impactor. The monodisperseaerosols are passed through the wind tunnel and sampling is done in the tunnel. Isokinetic sampling probes have been designed, fabricated and installed at different locations of the tunnel for sampling generatedmonodisperse aerosol particles. Probe velocity measuring device by using pressure sensor named (MPXV5050GP) is also fabricated for making the sample isokinetic. It has been found that the sampling of aerosols is better than the conventional sampling in the outlet pipe in respect of less particle loss. The monodisperse aerosols in the wind tunnel help us to carryout research on aerosol properties and to calibrate the air pollution measuring instruments available in the market.

The cattle trade or industry had since the establishment of the cattle market served as one of the most significant economic activities in Umuahia which served the entire Southern Provinces. The Umuahia cattle market within a short period of its establishment had become the distributing centre for the subregion. Cattle trade gained prominence in this town since before the inception of colonialism. The colonial regime took advantage of this trade to serve as a revenue generating industry. The organization of the cattle market was such that took care of various aspects of the trade; the most important aspect of the trade being the credit and credit recovery system. The network that was created as a result of this trade connected various towns and villages within and outside the Southern Provinces. We have employed various sources in this investigation such as oral, archival and written. We discovered that the cattle trade in this area served as one of the most important economic activity of the people. The cattle market became a Mecca of some sort for many other traders such as Kola nut traders, YanKoli traders and other petty trading. The need for the development of the cattle trade stems from the need of the people of the area for beef. That is to say it developed as a result of existence of the market for beef. The cattle market became the first point of contact between the cattle trading community and the people of the Southern Provinces. The importance of the cattle market and trade reached the most remote part of the Southern Provinces.

Purpose: To become a successful front office professional, a person needs to be comfortable with interacting with strangers and dealing with various hotel-guests issues. To do so effectively, a front office manager needs to understand and apply appropriate findings of psychology. Personality psychology is a branch of psychology that studies personality and individual differences. For years, practitioners of applied psychology have tried to help companies identify personality types of customers and teach them how to handle each of these. By understanding the personality styles of guests, front office managers can easily accommodate the needs of each type. This conceptual paper analyses some of the findings of personality psychology which have direct implications for front office managers and professionals.

For over a decade now, violent conflict has been a recurring decimal in Plateau State, most especially in Jos the state capital. However, some commentators have examined the simmering conflicts in Jos by adopting mono-causal perspective. Anchored on eclectic model of conflict analysis and with heavy reliance on secondary data, this study examined violent conflict in Jos. The study found that conflicts in Jos and elsewhere are caused by confluence of factors and as such solutions to conflict should embrace the various manifestations of conflict so as to proffer workable solutions.
