The output frequency of a self excited induction generator (SEIG) driven by wind turbine and supplies static load are controlled, using MATLAB/simulink. The PID controller which employed for turbine rotor speed control and hence the frequency regulation is proposed and simulated by MATLAB software package. The modern wind turbines implement pitch control in order to tap maximum energy at wind speeds lower than rated wind speed. They are simple and rugged in construction and offer impressive efficiency under varying operating conditions. The PID controller which employed for turbine rotor speed control and hence the frequency regulation is proposed. In this paper, a turbine blade pitch control has been assumed for this purpose.

Groundnut (Arachis hypogaea), a legume largely consumed by most populations in Africa, is widely grown as a food crop. This study is aimed at assessing the effect of some selected traditional processing methods (roasting with/without pod and boiling) on the protein and lipid composition of groundnut for optimal nutritional yield of the end product(s). Standard procedures were employed in the determination of the proximate composition of raw groundnut samples with emphasis on the lipid and protein content. Some selected traditional processing methods (roasting with/without pod and boiling with pod) were also employed and their effects on the lipid and protein content evaluated. Results demonstrated that groundnuts are excellent sources of protein and lipid. The processing technique, especially, dehulling before roasting manifested a significant (p<0.05) increase in the protein and lipid contents when compared with raw samples and other techniques.

Dermatoglyphics and Cheiloscopy Pattern in Hypertensive Patients; A Study in Ahmadu Bello University

Essential hypertension is sustained high blood pressure not attributable to a single cause but reflecting the interaction of multiple genetic and environmental influences. Dermatoglyphic involves the study of epidermal ridges present on the surface of palms, finger, soles and toes while cheiloscopy is the study of the grooves or furrows present on the vermilion border of the human lips. Finger and lip prints are known useful genetic markers in some congenital and clinical diseases; as such this study was aimed at determining the association between fingerprint and lip print patterns in hypertensive patients. The present study was carried out with hypertensive patients attending the outpatient clinic of Ahmadu Bello University Teaching Hospital (ABUTH), Zaria and was compared with a control group with normal blood pressure.

Regional or Universal literature? – A comparative study of the novelistic spaces of C.-F Ramuz and R

R.K Narayan and C.F Ramuz are two writers belonging to two countries known for their pluralistic natures: linguistic, ethnic and religious. In this form of diversity we see the simultaneous valorization of a cosmopolitan tendency as well as of the regional specificities. Such a situation that seems to be positive for society proves to be problematic in literature as universal and regional specificities begin opposing each other. A writer’s work is faced with the dilemma of being termed either as regional literature or world literature. The former is considered to be inferior to the latter. It is this dichotomy that is faced by R.K Narayan and C.F Ramuz. In this study we will investigate the theoretical framework, if any exists, forming the basis of such a categorization; the objective being, the determination of the factors that decide whether an author should be considered as a regional or a universal writer.

This paper investigates the optimum dispersion mapping for 40Gbps WDM system. The paper shows the performance of five channel WDM system with the channel spacing of 100GHz (0.8nm) by using non-zero dispersion shifted fiber (NZDSF) and dispersion compensation fiber (DCF). In addition it reveals both pre-compensation and residual dispersion per span can develop the performance. The modulation format used is RZ with 33% duty cycle. The optimum dispersion mappings for different channel numbers are discussed with different residual dispersions. By applying the optimum dispersion mapping, the impairments in the system can be minimized effectively .The analysis is done with OptiSystem software.
