Physicochemical characterization of the Jubilee crude oil
The physicochemical parameters and some contaminants of crude oil samples from the Jubilee oil field at Cape Three Points, western region and Saltpond oil field in Central region of Ghana were analyzed to classify and assess the quality of the crude oils. The physicochemical parameters determined were density, specific gravity, API, pour point, total sulphur content, salt in crude, total acid number, viscosity, reid vapour pressure and ash weight whereas the contaminants measured were water and sediments. Results from the physicochemical parameters for both samples showed a perfect Pearson’s correlation (r ?1). Low water and sediments levels (<1%) were recorded for both crude oils. This is an indication of low or minimal microbial growth and reduced ability of both crude oils to serve as a collector of water soluble metals and salts. This enhances the quality of the crude oils making them less fouling and corrosion resistant at high temperatures. High API values (API>30), coupled with low specific gravity, viscosity and pour point for both crude oils make them light crude oils. The sulphur concentration for both samples were low and within globally accepted range of 0.1-0.5 wt. % for sweet crude oil.

Post Mortem Evaluation of Mortality Trends in Deceased Type 2 Diabetes Mellitus Patients in two Tertiary Teaching Hospitals in Southeast Nigeria
Valid information on causes of death is a vital tool to the development of national and international health policies for prevention, better management, and control of diseases and complications. World health statistics indicated that Nigeria has the highest number of people living with diabetes in sub-Saharan Africa. Many life-threatening complications arise from type 2 diabetes mellitus (DM) from which many people die annually. This study assessed the current trends in mortality among type 2 diabetes patients to provide evidence based information on the dynamics of the disease for better case management and prevention of complications. The study was a cross-sectional retrospective descriptive study of dead type 2 diabetes patients using the death register and postmortem reports. Key data were extracted from death registers and analyzed with SPSS version 20 using descriptive and inferential statistics at a significant level of p<0.05. All the 229 and 91 deaths in NAUTH and ANSUTH due to DM complications were recorded. Diabetic foot ulcer (DFU) had the highest mean percentage death (51.9%). Diabetic ketoacidosis, hypertension, and hyperglycemia were implicated. Married patients had the highest cases of DM mortality 173(75.6%) for NAUTH and 52(57.2%) for ANSUTH. Type 2 DM is a major cause of morbidity and mortality worldwide and the associated burden is more prevalent in developing countries. Studies have shown that DFU with: infection, sepsis, DKA, hyperglycemia, and hypertension are very important complications among T2DM in Nigeria.

Potentials of fungus cultivating termites in a tropical ecosystem
Termites are significant agents behind organic decomposition in or at the surface of the soil. They thrive in great abundance in terrestrial ecosystems and play important role in biorecycling of lignocellulose... Macrotermitinae are the dominant termite family which cultivate fungal combs within the mound chamber. The termites and fungi, form a agricultural beneficiary relationship which is one of the most spectacular example for mutualistic symbiosis The key activities attributed to the fungal partner in this mutualistic symbiosis are extensive delignification of the substrate and the conversion of plant fiber to fungal biomass .The fungal population aids in the decomposition of cellulose and supply other nutritional requirements for the termite.

Poverty alleviation in Igbo traditional society: A response from indigenous religion
This paper discusses poverty alleviation in Igbo traditional society as one critical response from the people’s indigenous religious metaphysics. The Igbo people of Southeastern Nigeria are known from antiquity for their religiosity, industry and egalitarianism, among other virtues. As a people, they abhor material poverty (Ogbenye) and more so, relational poverty (Mgbenye). Therefore, from their world view which has a porous demarcation between the secular and the sacred, they evolved poverty alleviation schemes. The findings of this paper reveal that the success stories of these programs were based on love of neighbour, contentment, honesty, industry, communitarian spirit and other cultural values which were made robust by their indigenous religion. Based on the findings, this work therefore calls on the Igbo indigenes both at home and in diaspora to continue along these moral virtues and positive social values got from their ancestors as they do not contradict the ways of Christianity which majority of us have embraced. The implication of this persuasion is the need by both Igbo people and all persons on earth to eschew immoral vices such as corruption, sale of babies and human parts, assassination, fraud and human trafficking, looting and thuggery, prostitution, cultism and ritual money, et cetera as means of fighting poverty which are prevalent today in many indigenous and modern societies. The methodology employed in this work is “Culture Area Approach” which means that this study focused on Igbo cultural context with special interest on her traditional poverty alleviation methods as peculiar evolutions from her Indigenous Religion.

Proportional and angular photogrammetric analysis of the soft tissue facial frontal view of 16-30 year olds in Shiraz, Iran
Facial beauty is becoming more and more important worldwide. This is defined as being close to what is advertised as attractiveness (for example by media) and is determined mainly by golden proportions. This study aimed to observe the soft tissue facial angular and proportional norms of South Iranian population attending Shiraz Dental School's clinic. Methods and material: Seventy subjects (34 males and 36 females; 16-30 years of age)with Persian origin who had a skeletal class 1 pattern and almost well-aligned maxillary and mandibular dental arches who participate in this cross-sectional study were selected from patients attending Shiraz Dental School's orthodontic clinic in 2013. Standardized frontal facial view digital photographs were taken from subjects and traced. Four angular and eight proportional facial variables were analyzed by using Autocad software. For statistical evaluation a Student’s t -test was used and the reliability of the method was assessed by using Intraclass Correlation Coefficient within a four week interval. Results: Men had a higher facial asymmetry, a higher Facial Index, a higher proportion of the distance between inner canthus of the eyes divided by the mean of the width of the right and left eyes, and a lower facial aperture modified angle average than females. Conclusion: The average measurements of most facial variables of this study's population deviated from the ideal values suggested in texts and from those of the Brazilian Caucasian population.
