In this study, the photocatalytic performance of Tb, N co-doped titania nanocomposites was evaluated by degradation of methylene blue. The effects of calcination temperature and N doping amount on the catalytic activity were analyzed. In addition, the photocatalytic reaction kinetics of the nanocomposites was also discussed. The results showed that Tb-N-TiO2 exhibites the highest photocatalytic performance when the calcination temperature is 600 °C and the optimal doping amount of N is 6 %.

The aim of this study was to assess the occurrence of bacterial contaminants in fingernails of food vendors in three selected markets of Gboko Local Government Area, Benue State, Nigeria. A total of thirty (30) nail samples were collected from food vendors, 10 samples from each market using new razor blade for each subject. Standard laboratory procedures were carried out on nail samples including inoculation, cultural characterization, microbial count and biochemical identification of bacteria.

Background and Objectives: Man’s health is determined by some factors which play a leading role in making man what he is, these conditions are social, economic, political, natural, manmade and environmental factors. The main aim of this research was to investigate people’s access to quality water supply and the common bacteria found in the stored drinking water of household in the study area. Methods: To achieve these objectives an Experimental Design (laboratory study) was adopted, water samples were collected from 100 households in target communities.

Aim: The central aim of this research was to investigate people’s practice of sanitation and personal hygiene, prevalence of diarrheal diseases and to suggest ways of reducing the incidence of these diseases in the community. Methods: To achieve these objectives two methods (interview and observation) were used to study the problem so that the strength of each method could conquer the deficiencies of a single method studies. The entire study was conducted between May and July 2017.

La spiruline est un complément alimentaire peu consommé au Niger. L’objectif de cette étude est d’évaluer la consommation et l’acceptabilité de la spiruline dans la ville de Niamey. Pour atteindre cet objectif, une étude descriptive transversale à viser analytiquea été réalisée dans les cinq (5) l’arrondissements communaux de la ville de Niamey. Aussi, l’étude a concerné un échantillon de 992 ménages. Les résultats obtenus ont montré que 4,9 % seulement des enquêtées connaissances la spiruline, parmi lesquels 37,5% l’ont une fois consommé.

There is a vast time approach evolution in medication and there preparation methods which has brought into medicines which are even more effective and target the specific cells and not the entire body and produce more biological effect rather than producing adverse effects one of these is liposomal vesicles which has been evolve over time. Vesicular systems are highly ordered single or multiple assemblies Bilayer of concentrated lipids.

Solubility is the significant component for medication adequacy, freedom of the course of administration Gigantic proportions of recently discovered medications are water-insoluble, and hence poorly bioavailable adding to forsook improvement efforts. These so‐known as Brickellia's competitors can now be conveyed through detailing them into Nanosuspension. Nanosuspension technological know-how solved the drawback of medications that are inadequately watery dissolvable and have less bioavailability.

Background: Perioperative shivering is one of the most common problems in parturients receiving regional anesthesia during cesarean section. Although shivering is a protective reflex to increase the core temperature by involuntary contraction of muscles, it also leads to adverse effects like increasing oxygen consumption and affecting wound healing.

Introduction: The objectives of neuroanesthesic management should focus on generating unconsciousness, amnesia and antinociception, maintaining cerebral perfusion pressure, control of intracranial pressure, avoiding secondary damage due to hypoxemia, hypo or hypercapnia, hyper or hypoglycemia, to thus being able to provide optimal surgical conditions, allowing in turn early neurological evaluation. Objectives: The present review aims to evaluate in a practical way the main pharmacokinetic models and correlate them with the changes that occur in neurosurgical patients.

Cleft lip and palate are the most common congenital facial malformations in the world. For a long time, research and scientific studies have focused on cleft lip and palate in order to understand more about it, but also to find support strategies for parents who are still confronted with the traumatic reality of the occurrence of a congenital malformation. However, it appears that in the sub-region and particularly in Senegal, few studies have focused on the psychological experience of mothers of cleft lip and palate children.
