Abstract: A tridentate Schiff base ligand, (E)-2-(4-dimethylbenzydimino) glycylglycine (glygly-DAB), derived from the condensation of 4-Dimethylaminobenzaldehyde (DAB) and glycylglycine (glygly) together with its Co(II), Ni(II), Cu(II) and Zn(II) complexes have been synthesized and characterized using various physico-chemical methods including C,H,N elemental analysis, melting point determination, molar conductivity measurement, IR, 1H NMR and UV-Vis. The ligand and metal complexes were screened in vitro for antimicrobial and antifungal activities on four bacterial strains (Staphylococcus aureus, Escherichia coli, Salmonella thyphi and Pseudomonas aeruginosa) and two fungal strains (Candida albicans and Cryptococcus neoformans). glygly-DAB showed remarkable antifungal activities on all the fungal strains and antibacterial activities on one bacterial strain.
Examining the Mechanism for the Transferability of Leadership Elements to Students: The Case of the Catholic University Institute of Buea (CUIB)  [PDF]
Maurice Ayuketang Nso
Open Journal of Leadership (OJL) , 2018, DOI: 10.4236/ojl.2018.72009
Abstract: This paper recommends what could be a standard definition for the word “leadership”, as it found out that there has been no standard way for defining leadership, and that others have defined leadership based on the leadership elements a leader has but failed to rethink that one could be a bad leader and as such the leadership elements could not be transferred (passed on) to heirs for the simple reason that no one likes bad things.
Fostering accurate HIV/AIDS knowledge among unmarried youths in Cameroon: Do family environment and peers matter?
Zacharie Tsala Dimbuene, Barthelemy Kuate Defo
BMC Public Health , 2011, DOI: 10.1186/1471-2458-11-348
Abstract: Data were drawn from the Cameroon Family Life and Health Survey (CFHS) conducted in 2002. The CFHS collected information on a representative sample of 4 950 people aged 10 years and over nested within 1 765 selected households from the 75 localities forming the administrative prefecture of Bandjoun, using detailed questionnaires about family, HIV/AIDS/STDs knowledge, sexual behaviors, contraception, health, media exposure, household assets and neighborhood characteristics. The survey cooperation rates were high (97%). For the purpose of this study, a sub-sample of 2 028 unmarried youths aged 12 - 29 years was utilized.Overall, 42% of respondents reported accurate knowledge of documented HIV transmission routes whereas 21% of them had inaccurate knowledge such as AIDS can be transmitted through mosquito bites or casual contact with an infected person. Only 9% of respondents were knowledgeable about all HIV prevention strategies. Multivariate analyses showed that family structure, communication with parents/guardians and peers about sexual topics were significantly associated with accurate HIV knowledge. Additionally, age, education, sexual experience and migration had significant effects on accurate knowledge. Finally, living in poor households and disadvantaged neighborhoods significantly increased inaccurate knowledge of HIV transmission modes and prevention strategies.This paper evidenced the limited effects of HIV interventions/programmes in sub-Saharan Africa. Indeed, few respondents reported accurate knowledge about HIV transmission routes and prevention strategies. Findings showed that the role of family environment as source of accurate HIV knowledge transmission routes and prevention strategies is of paramount significance; however, families have been poorly integrated in the design and implementation of the first generation of HIV interventions. There is an urgent need that policymakers work together with families to improve the efficiency of these interven
Modeling Hierarchically Clustered Longitudinal Survival Processes with Applications to Child Mortality and Maternal Health
Kuate-Defo, Bathélémy
Canadian Studies in Population , 2001,
Abstract: English This paper merges two parallel developments since the 1970s of newstatistical tools for data analysis: statistical methods known as hazard models that are used foranalyzing event-duration data and statistical methods for analyzing hierarchically clustered dataknown as multilevel models. These developments have rarely been integrated in research practice andthe formalization and estimation of models for hierarchically clustered survival data remain largelyuncharted. I attempt to fill some of this gap and demonstrate the merits of formulating and estimatingmultilevel hazard models with longitudinal data. French Cette étude intègre deux approches statistiques de pointe d'analyse des donnéesquantitatives depuis les années 70: les méthodes statistiques d'analyse desdonnées biographiques ou méthodes de survie et les méthodes statistiquesd'analyse des données hiérarchiques ou méthodes multi-niveaux. Ces deuxapproches ont été très peu mis en symbiose dans la pratique de recherche et parconséquent, la formulation et l'estimation des modèles appropriés aux donnéeslongitudinales et hiérarchiquement nichées demeure essentiellement un champd'investigation vierge. J'essaye de combler ce vide et j'utilise des données réellesen santé publique pour démontrer les mérites et contextes de formulation etd'estimation des modèles multi-niveaux et multi-états des données biographiqueset longitudinales.
Etiologic Aspects of Epileptic Seizures of Recent Onset in HIV-AIDS Infected Subjects at the Yaounde Central Hospital (Cameroon)  [PDF]

Abstract:

Introduction: Patients infected with HIV usually develop neurological complications. Seizures are amongst clinical manifestation of these neurological complications of HIV infection. We report on 150 HIV positive patients who presented with newly onset seizures. Objectives: Our objective was to evaluate the influence of HIV infection on epilepsy and particularly to look for the most common epilepsy induced complications in our context. Methodology: We recruited all patients infected with HIV and who consulted at the outpatient or admitted in the in the neurology unit of the Yaounde Central Hospital, for seizures from August 1st 2008 to December 31st 2009. All the patients were aged above 18 years, black and of Cameroonian nationality. All those who had a family history of epilepsy, as well as those with a personal history of epilepsy were excluded from the study. Results: During the period of study, we recruited 150 patients aged 38.7 ± 9.9 years and with an M/F sex ratio of 0.76. Generalized seizures were observed in 66% of patients, of whom 58% were HIV 1 positive and an average CD4 count of 65.4 ± 11.7/μl. Cerebral toxoplasmosis was the most common etiology observed in 30% of cases. Discussion: This study being hospital based must have selected the most serious patient with severe immunodeficiency. This can explain why a precise etiology was found in the majority of cases. Modi et al. (1999) found a space occupying lesion in 53%, meningitis in 22% and 25% without identifiable etiology in black South Africans. Central nervous system tuberculosis was the most frequent cause encountered in 64% of patients with etiologies. Conclusion: Seizures are one of the principal manifestations of HIV infection or its complications. Their prevalence is 9.5% in our study. Cerebral toxoplasmosis is the most frequent etiology in our study, followed by cryptococcal meningitis and tuberculous meningitis.

Abstract:
The reaction of 2-ethylimidazole and zinc formate monohydrate in 1:2 ratio in toluene leads to the formation of bis(2-ethylimidazole)bis(formato)zinc(II)-water (1/1), [Zn(N2H8C5)2(OCHO)2]·H2O, 1 which has been characterized by several techniques, including elemental and thermal analyses, IR, 1HNMR and 13CNMR spectroscopies, single crystal X-ray diffraction and DFT studies. The results obtained show that this complex crystallizes in the orthorhombic crystal system of the Pbca space group, with cell parameters a = 14.7230(2) Å, b = 7.3880(10)

Electronic Journal of Biotechnology , 1998,
Abstract: at first some general considerations about specificity and characteristics of ssf, their advantages and disadvantages as compared to lsf, are presented. microorganisms involved in solid substrate fermentations are identified, considering the better performances of filamentous fungi. the solid substrates and their basic macromolecular compounds are detailed in relation to this complex and heterogeneous system. biomass measurement is examined in detail, as well as environmental factors, both essential for studying and optimising solid substrate fermentations.
Reflections on production planning and control (PPC)
Bonney, Maurice;
Gest?o & Produ??o , 2000, DOI: 10.1590/S0104-530X2000000300002
Abstract: the paper examines the current state of production planning and control (ppc), identifies some technical and systems changes that have occurred over recent years and links these with the requirements being placed on companies by the market. ppc is being asked to respond effectively to these internal and external changes by being more dynamic and providing better control of resources and delivery performance. some of the requirements to be satisfied by the new ppc systems are identified. to meet these requirements it is suggested that better understanding is required of how different factors affect ppc systems performance and that administrative systems need improving. the quantitative, administrative and behavioural aspects of ppc are discussed. a framework for developing an agenda for action and research is provided.
