University of Ngaoundéré or Université de Ngaoundéré is located in Ngaoundéré,Adamawa region of Cameroon. It was founded in 1982.The University of Ngaoundere is among one of the top higher education institutions in Cameroon. It is one of the state owned universities. In January 1993 the government of Cameroon launched a major reform of its higher education system. Six universities were created out of one large university and four small university centres.HistoryThe University of Ngaoundere was created by the Presidential Decree of 19 January 1993 transforming the Ngaoundere University Centre into a statutory State owned University.Initially made up of two professional schools and four faculties, this institution today has four professional schools and faculties with an estimated 17,000 student population and welcomes students from all regions of Cameroon and neighbouring countries in the sub-region like Chad and the Central African Republic.MissionsThe University of Ngaoundere responsible: to develop and transmit knowledge. for research development and training. to carry to the highest level and at the best rhythm of progress the superior forms of culture and research provide access to higher education to all those who have the capacity and will. to contribute by supporting development and social and cultural promotion. to develop practice of bilingualism.OrganizationThe Board of Directors is the supreme body of the university, which ensures the implementation of the development plan of the University as defined by the Council of Higher Education and Scientific and Technical Research and approved by the President of the Republic of Cameroon.The University of Ngaoundere is guide administratively and academically by a Rector, appointed by presidential decree.The Rector chairs the University Council, the competent authority in the academic and scientific field. He is assisted at the administrative level by the Central Government consisting of a Secretary-General, three vice-presidents and four administrative units.Faculties and Schools:FacultiesFaculty of Arts Letters and Human scienceFaculty of ScienceFaculty of Economic Science and ManagementFaculty of Law and Political scienceFaculty of Arts Letters and Human scienceThe Faculty of Arts, Letters and Social science has seven departments:• The English Department• Department of Anthropology and Sociology• Department of Arts• Department of French• Department of Geography• Department of History• Department of Arabic Language and Civilization• Department of Linguistics and African languages.Faculty of ScienceThe Faculty of Science has seven Departments:• Department of Physics• Department of Mathematics and Computer Science• Department of Biological science• Department of Earth science • Department of Chemistry• Department of Environmental science• Health science and Biomedical scienceFaculty of Economic Science and the ManagementThe Faculty of Economics and Management science has four Departments:• Department of Accountancy and Finance;• Department of Management, Strategy and Forecasting;• Department of Marketing ;• Department of Monetary and Banking Economics.Faculty of Law and Political scienceThe Faculty of Laws and Political Science has three Departments:• Department of Public Law ; • Department of Private Law ;• Department of the Legal Theory and Epistemology'Detailed information about the major schools of the University of NgaoundereSchools'School of Geology and Mineral Exploitation National School of Agro-Industrial science School of Science and Veterinary Medicine University Institute of Technology Wikipedia.

This study was aimed to evaluate the dose dependent effect of pregnant mare serum gonadotropin and human chorionic gonadotropin on in vitro maturation goat oocytes. The study was planned in 2 experiments. In the first experiment effect of pregnant mare serum gonadotropin supplementation on nuclear maturation of goat oocytes using 5 different concentrations of PMSG, was studied. The treatment was divided into group 1 (control medium containing TCM-199, sodium pyruvate (0.25mM), gentamycin (50μg/ml), L-glutamine (100μg/ml), estradiol 17-ß (1μg/ml), BSA (3mg/ml), supplemented with 10% FBS); group 2 (control medium + 10 IU/ml PMSG); group 3 (control medium + 20 IU/ml PMSG); group 4 (control medium + 30 IU/ml PMSG); group 5 (control medium + 40 IU/ml PMSG); and group 6 (control medium + 50 IU/ml PMSG). The oocytes of these treatment groups were matured in maturation media for 27 h in humidified atmosphere of 5% CO2 at 38.5°C in a CO2 incubator. The maturation rates achieved in groups 1-6 were 20.0, 48.51, 74.63, 74.15, 75.0 and 76.33%, respectively. In experiment 2, the effect of hCG supplementation on nuclear maturation of goat oocytes using 3 different concentrations of PMSG, was studied. Second experiment was divided into group 1 (control medium + 20 IU/ml PMSG +10IU/ml hCG), group 2 (control medium + 20 IU/ml PMSG +20IU/ml hCG) and group 3 (control medium + 20 IU/ml PMSG +30IU/ml hCG). The maturation rates achieved in groups 1-3 were 77.0, 85.19 and 84.22%, respectively. It can be concluded that supplementation of 20 IU/mL PMSG and 20IU hCG in maturation media significantly increased the maturation rate.

An indirect F-function method is introduced to solve the Zakharov-Kuznetsov equation with power law nonlinearity and nonlinear dispersion along with time-dependent coefficients. Taking advantage of the elliptic equation, this F-function is used to map the solution of the Zakharov-Kuznetsov equation to those of the elliptic equation. As a result, we obtain exact spatiotemporal periodic traveling solutions. Two forms of this model are studied. The constraint relation between these time-dependent coefficients is established for the Jacobi elliptic function solutions to exist. This equation is then investigated with generalized evolution. © 2010 Elsevier B.V. All rights reserved.

The accurate evaluation of redox potentials in various media and the ability of electron transfer in some biological or chemical reactions are subject to the determination of the accurate gas phase thermodynamic data of the electron. These data are also useful to describe with a high accuracy the movement of the electron in a stellar core. However, these data were not available at all temperatures, and the available data were not sufficiently accurate. I addressed this matter using a robust and reliable self-consistent iterative procedure which determines the entropy of a gas phase free electron and, thereafter, allows the calculation of its heat capacity, enthalpy, and free energy. Extremely accurate analytic expressions of the aforementioned thermodynamic parameters were provided at all temperatures. The thermodynamic parameters of the gas phase electron are now known at all temperatures (integer or noninteger) in the standard atmosphere with a high accuracy. Analytic expressions proposed for the thermodynamic parameters are highly advisable where iteratively computed data are unavailable. Note that at room temperature (T = 298.15 K), the values recommended for the thermodynamic parameters of the gas phase electron are S = 22.6432 J mol-1 K-1, CP = 17.1062 J mol-1 K-1, ΔH = 3.1351 kJ mol -1, and ΔG = -3.6160 kJ mol-1. © 2013 American Chemical Society.

The purpose of this research is to create a thermal comfort database in three climatic regions in Cameroon. This will help to define guidelines for constructing more comfortable buildings in Cameroon. There is not enough data regarding comfort in residential environment in the intertropical sub Saharan Africa. Thus experimental and subjective results of hygrometric thermal comfort conducted in 290 buildings located in three cities of the equatorial climatic zone of Cameroon is presented. An adaptive approach according to ASHRAE 55/2004, ISO 7730 and 10551 was adopted. A specific questionnaire has been elaborated for the investigation. 710 questionnaires in the dry season and 410 in the rainy season were distributed to inhabitants and filled while different experimental values of indoor parameters were measured. The comfortable temperature ranges for the three cities was found between 22 °C and 29 °C. The 61.24% of voters found acceptable their thermal habitat, the 13.72% considered it neutral. © 2014 Elsevier Ltd.
