Biotechnological Tools for Environmental Sustainability: Prospects and Challenges for Environments in Nigeria—A Standard Review

Abstract: The environment is a very important component necessary for the existence of both man and other biotic organisms. The degree of sustainability of the physical environment is an index of the survival and well-being of the entire components in it. Additionally, it is not sufficient to try disposing toxic/deleterious substances with any known method. The best method of sustaining the environment is such that returns back all the components (wastes) in a recyclable way so that the waste becomes useful and helps the biotic and abiotic relationship to maintain an aesthetic and healthy equilibrium that characterizes an ideal environment. In this study, the method investigated includes biological method of environmental sustainability which seeks to investigate the various biotechnological tools (biotools) in current use and those undergoing investigations for future use.

Development Planning in Nigeria: Reflections on the National Economic Empowerment and Development Strategy (NEEDS) 2003-2007

Abstract: Nigeria returned to democratic rule in 1999 with the enthusiasm to chat new political and socio- economic dispensation. The introduction of National Economic Empowerment and Development Strategy (NEEDS) as a medium term planning strategy was a blueprint for new order. It contains all the envisaged policies and programmes of the federal government for the period 2003-2007 and far beyond, and serves as the fountain of the much-touted Obasanjo's reforms. NEEDS is not only a macro-economic plan document, but also a comprehensive vision, goals and principles of a new Nigeria that would be made possible through four key policies of wealth creation, employment generation, poverty eradication and value reorientation. This paper is a reflection on NEEDS. Using historical and content analysis methods, the paper explores common indices of development planning in the country. It reveals that NEEDS is not different from previous development plans in Nigeria, despite the claims to the contrary. While claiming to be a home-grown plan, it is very much in line with the wishes of the international agents of developed capitalist economies; there is lack of commitment of the leadership in pursing plan objectives; corruption is still rife and priority in selecting plan projects is still poor. The paper recommends among others, the need for committed leadership, continuity with NEEDS II document, drawing adequate scale of preference in choosing policies and programmes, and determined efforts to break from the crutches of neo imperialist and neo colonial tendencies of the developed countries.

Evaluation of blood pressure and indices of obesity in a typical rural community in eastern Nigeria.

Abstract: Aim: With increasing urbanization of lifestyle, cardiovascular morbidity and mortality have been on the increase in Africans. Studies on cardiovascular risk factors in rural communities in South East Nigeria are scarce. This study focused on hypertension and obesity in adult Nigerians dwelling in a rural setting in Eastern Nigeria. Materials and Methods: A total of 218 participants from the rural community were recruited into the study. A questionnaire was used to assess prior knowledge of their weight and blood pressure status as well as drug history for those found to have hypertension. Each participant's blood pressure was measured and any value ≥140/90 mmHg was regarded as high blood pressure (HBP). Their heights and weights were measured and their body mass indices (BMI) calculated using the standard formula of BMI = Weight in Kg/Height in m 2 ; BMI ≥30 Kg/m 2 was referred to as global obesity. Their waist circumferences (WC) were also measured and any value ≥102 cm for males and ≥88 cm for females was regarded as abdominal obesity. Results: The general prevalence of HBP in the rural community was 44.5%. The prevalence of HBP increased as age increased and awareness about HBP was low (15.2%). Females were more aware than the males. The prevalence of HBP was higher in males (49.3%) compared with their female counterparts (42.3%), whereas the females had a higher prevalence of all forms of obesity (abdominal: 36.2%, global: 14.8%) compared with the males (abdominal: 14.5%, global: 10.1%). Higher BMI was associated with higher systolic and diastolic BP values. Hypertensive participants had higher BMI and WC than those who had normal BP. Conclusion: The prevalence of both hypertension and obesity seems to be increasing in rural communities in Nigeria and thus, the available prevalence documented in previous studies for rural communities may no longer represent the current trend. Awareness of the participants about these major cardiovascular risk factors is still very low. Higher BMI was associated with higher values of both systolic and diastolic BP.

The First VERA Astrometry Catalog

Abstract: We present the first astrometry catalog from the Japanese VLBI (very long baseline interferometer) project VERA (VLBI Exploration of Radio Astrometry). We have compiled all the astrometry results from VERA, providing accurate trigonometric annual parallax and proper motion measurements. In total, 99 maser sources are listed in the VERA catalog. Among them, 21 maser sources are newly reported while the rest of 78 sources are referred to previously published results or those in preparation for forthcoming papers. The accuracy in the VERA astrometry are revisited and compared with those from the other VLBI astrometry projects such as BeSSeL (The Bar and Spiral Structure Legacy) Survey and GOBELINS (the Gould's Belt Distances Survey) with the VLBA (Very Long Baseline Array). We have confirmed that most of the astrometry results are consistent with each other, and the largest error sources are due to source structure of the maser features and their rapid variation, along with the systematic calibration errors and different analysis methods. Combined with the BeSSeL results, we estimate the up-to-date fundamental Galactic parameter of $R_{0}=7.92\pm0.16_{\rm{stat.}}\pm0.3_{\rm{sys.}}$~kpc and $\Omega_{\odot}=30.17\pm0.27_{\rm{stat.}}\pm0.3_{\rm{sys.}}$~km~s$^{-1}$~kpc$^{-1}$, where $R_{0}$ and $\Omega_{\odot}$ are the distance from the Sun to the Galactic center and the Sun's angular velocity of the Galactic circular rotation, respectively.
