Remote Microcontroller Based Monitoring of Substation and Control System Through GSM Modem
As complexity of distribution network has grown [7], automation of substation has become a need of every utility company to increase its efficiency and to improve quality of power being delivered [5]. The proposed project which is GSM cellular network based controlling of substation [5][12] will help the utility companies, by ensuring that their local-substation faults [8][9][10] are immediately realized and reported to their concerned departments via GSM, to ensure that duration of power interruption is decreased. The measured parameters will be sending in the form of SMS messages. The microcontroller will interact with the sensors installed at the local substation and perform task as commanded [3]. Electrical parameters like current, voltage will be compared continuously to its rated value [13] will help protect the distribution and power transformer from burning due to overload, short circuit fault, over voltages and surges. Under such conditions, entire unit is shut down via the control section comprising of relays sensing it, and immediately turning the circuit breaker off. SMS alerts can also be generated to indicate this. The use of GSM makes the substation intelligent [4] in the sense that it is able to transmit alerts and information and receive commands. This enables to reduce labor cost at substation and saves time. Thus the monitoring and working efficiency of the sub-station will drastically increase.

Roles of school supervisors in Nigerian secondary school
The research aims to determine the roles of school supervisors (SS) for improving teachers teaching and learning(TTL). Ministry of education (MOE) appreciates report from supervisors and recommendation submitted.Data collection was through questionnaires 16 out of 22 respondent's return.Data were analysed using descriptive and multiple regression. The findings revealed that Teachers prefer special supervision, supervisors check Teachers attendance register regularly, lesson notes and communicate teaching lapses. The findings will improve the Supervisors role and help them strengthen SS. Training and retraining of supervisors motivation, trustworthy and collaboration of MOE. The novelty of research focus on supervisors’ role and improvement of TTL.

Studies of Temporal Variations of Species Diversity and Abundance of Marine Birds in Red Sea Region
Massawas and its surrounding beaches can support a diversity of marine birds along with the Red sea, for weather seasonal, annual, and spatial factors that affect bird richness and abundance on public beaches. To do so, we conducted two years of bird surveys on the beaches. These beaches are permanent natural water bodies, and are important for bird wildlife because they are stable resources for food, water and also good ground for mating purpose. The permanent water bodies are constant and limited for its geographical areas under natural conditions. We studied the marine water birds which are both migrant and resident; its species richness and diversity were studied in Massawa and its surrounding beaches in the Red sea region. It is a good for marine food source and also near by areas for marine birds there was natural vegetation in the seasons and are less important for agricultural resources. These areas were supposed to be earlier in rich resource for different marine bird’s species and may be sometimes disturbed by the seasonal sea tides and also by tourists. The study reveals that there are different species of birds as discussed below. We conclude our study that reductions in the rate of population decline of the observed species of marine bird biodiversity. To protect such species great care must be exercised either by governmental or by non-governmental agencies. Across all species we found that there are 10 marine bird species of this region and calculated there values the bird species and abundance and obtained low values indicating low bird richness and abundance, it may be due to strongly affected by seasons, natural habitat and the availability of food and are the basis for conducive environment for breeding for maintaining next generation.

Synergistic antibacterial activity of the mangrove plant leaf extracts and non mangrove medicinal plant seed extracts against the multi drug resistant bacterial human pathogens
This study was aimed to evaluate the synergistic antibacterial activity of the mangrove species Avicina marina and Rhyzophora apiculata leaf extracts tested with the non mangrove South Indian medicinal plants, Terminalia chebula, Punica granatum, and Vitis vinifera seed extracts against the multi drug resistant (MDR) bacterial isolates of clinical origine. The antibacerial synergistic activity of the chosen plant extracts were studied by agar well diffustion method. Compared to the single plant extracts, the antibacterial activity expressed by the combination of the Mangrove leaf extracts with the non mangrove medicinal plants seed extracts found to be greater due to the synergism . We recomond the T.chebula seed extract , which can be given / taken along with the mangrove plant leaf material to treat the ailments / drug resistant bacterial infections. We also suggest that the traditional medicine system can adapt the practice of giving the combination of the discrete plant materials / extracts to treat the bacterial infections especially to treat the drug resistant infections to achieve the success in their system of medical practice.

Tax Incentives and Corporate Financial Performane in Nigeria: Evidence From Firms Level Panel Data
While the philosophy behind tax incentives and corporate financial performance is appealing, its analytical content and utility remains somewhat controversial and of empirical interest. This study assesses the causal influence of tax incentives and corporate financial performance on a sample of 50 listed companies in the NSE, covering the period of 2006-2010. The postulated hypotheses were tested, using multiple linear regression (MLR) analysis. With r values of .996, .984, and .948 very basic aprori reasoning established is the existence of a robust dimension and the three measures of corporate financial performance, namely return on equity, return on sales and profit after tax. The significance of this attempt can be seen in the ability of the models to permit inter-sector; inter-industry, inter-institutional, as well as inter-country comparative analysis relating to the specified variables. Further empirical research is however recommended to verify the validity of these submissions and the overall explanatory power of the models constructed, using data drawn from developing countries. Keywords: Corporate Financial Performance, Profit After Tax, Return on Equity, Return on Sales, Nigeria.

The social historian in the transformation of Nigeria
Social history, often called the new social history, is a broad branch of history that studies the experiences of ordinary people in the past. In its "golden age" it was a major growth field in the 1960s and 1970s.History is important because it helps us to understand the present. If we will listen to what history has to say, we can come to a sound understanding of the past that will tell us much about the problems we now face. History taught to our children is playing a role in shaping their values and beliefs. This paper examine the responsibility of historians in constructing the faulty, ethnocentric and historical account of the past and contemporary Nigerian State.
