An Investigation to Determine The Resistance of The Tick (blue tick) to Amitraz in Selected Areas of Zimbabwe.

Abstract The purpose of this study was to determine if the Boophilus species spectrum of ticks infesting cattle owned by resource limited farmers in the state owned communal land areas of Zimbabwe, are resistant to Amitraz. The study was also aimed at finding a concentration of the acaricide that the tick species are susceptible to, and can give at least 99.9% mortality. Five districts were selected from the Matabeleland South province and five farms were randomly selected from each dis...

A Comparative Study Of The Effectiveness Of Alkaline Soaking, Bleach And Boiling For Pasteurization Of Substrate In The Cultivation Of White Oyster Mushroom (Pleurotus Ostreatus)

Abstract A study was carried out on substrate pasteurisation for P. ostreatus cultivation. The major aim of this work was to compare the effectiveness of wood ash, hydrated lime, bleach and boiling for pasteurisation of the substrate for cultivation of white oyster mushroom, Pleurotus ostreatus, on maize straw. To achieve this objective, weed occurrence, the number of days to completely colonise the straw (NDCC), the number of days to initiate primordial sprouting (NDIPS), the number of...

Phytochemical Analysis Of Cleome Viscosa.

ABSTRACT Cleome viscosa Linn (Capparaceae) commonly known as “wild or dog mustard” is an annual sticky herb found as a common weed all over the plains of India and through the trophics of the world. The whole plant and its parts (Leaves, pods and roots) are widely used in traditional and folkloric systems of medicine. Cleome viscosa were extracted with and all these extract were screened for the presence of various metabolites (primary and secondary) including proteins, carbohydra...

Modulatory Effects Of The Crude Methanol Leaf Extract Of Cissampelos Owariensis On Some Biochemical Parameters In Bleomycin-Induced Lung Fibrosis In Male Wistar Rats

ABSTRACT Antioxidants have been shown to play protective role in the treatment of bleomycin-induced lung fibrosis. The goal of the study was to determine the effect of Cissampelos owariensis (CO) leaves, an alkaloid rich antioxidant on BLM-induced lung fibrosis in rat models. The CO (UIH22559) leaves were extracted using methanol and fractionated using vacuum liquid chromatography (VLC) to obtain the ethyl-acetate fraction (EAF) and methanol fraction (MEF). The active component of CME wa...

ABSTRACT This study aimed at investigating the influx of unqualified teachers in teaching Biology in secondary school in Sokoto metropolis. With the view of finding solutions to improve the situation at stake. Criteria used in selecting the schools were random selection technique in which five schools were selected from each of the two (2) local government areas of the Sokoto metropolis, namely (Sokoto North and Sokoto South respectively), as a sample for this research. Questionnaire wa...

Effect Of Two Kinds Of Solvent On Chemical Composition Of Cymbopogon Citratus Oil

ABSTRACT The experiment was designed to determine the effect of two different solvent (N-hexane and petroleum ether) on chemical composition of lemongrass oil. The oil was extracted from lemongrass using Nhexane and petroleum ether using soxhlet extraction method. The chemical composition of essential oil obtained were analyse using GC-MS machine. The result shows 4.4% of oil were obtained from lemongrass using N-hexane and 4.9% were obtained using petroleum ether. The composition anal...

Antinutritional Composition Of Securidaca Longepedunculata (Violet Tree)

ABSTRACT The antinutritional composition of leafs and stem bark s. longepedunculata were investigated using standard analytical methods. The leafs and stem bark of S. longepedunculata was air dried and the sample was pulverized for the determination of anti-nutritive contents. The antinutritional continents viz phytate, oxalate, nitrate and cyanide were determined in this investigation. Nitrate content was significantly (p

Evaluation Of Storage Control Point And Implicated Pathogens On Fast Moving Consumer Goods - Ogun And Lagos States As Case Study

ABSTRACT Ensuring food safety to protect public health remains a significant challenge in both developing and developed countries and food borne illness prevention system will depend on the extent of food safety control in place through food production, processing and distribution, keeping food at safe temperature and using safe water and raw materials. These stages of production are some of the important points determining food safety. The high level of bacterial contamination leading t...

Evaluation Of Some Nutritional, Physicochemical And Phytochemical Parameters Of Dioscorea Rotundata (White Yam) Flesh And Peels Exposed To Four Different Storage Patterns In Nigeria.

ABSTRACT The hue and cry of food insecurity in Nigeria prompted the curiosity of this study. This study investigates the evaluation of some nutritional, physicochemical and phytochemical parameters on Dioscorea rotundata (white yam) flesh and peels exposed to four different storage patterns in Nigeria. Four storage patterns and 20 tubers of yam were used for this study. The yams were grouped into the four storage patterns: Open Sided, Yam Barn, Heap on Floor and Platform Storage, and th...

Comparism Analysis Between Microscopy And Filariasis Strip Test (FTS)

ABSTRACT Lymphatic filariasis (LF) is caused by infection with threadlike worms called Wuchereria bancrofti. There had been different methods of diagnosing Filariasis. The two major diagnosing method is the Filariasis Test strip and the Microscopy test. This project is to compare the efficiency between the Microscopy test and Filariasis Test Strip (FTS) Night blood sampling method collected between the hours of 10pm – 2am and Filariasis test strip is done same hours using 2 drop of bl...

EFFECTS OF DRYING METHODS ON NUTRIENT CONTENTS OF Moringa oleifera (Lam.) LEAVES

ABSTRACTThe study was carried out to determine the effect of drying methods on the nutrient contents of Moringa oleifera at the Agric. Chemical Laboratory (Usmanu Danfodiyo University Sokoto) and The Energy Research Field of Sokoto Energy Center, Sokoto. Fresh leaves were collected and cleaned then dried using different drying methods viz. shade drying, solar drying, oven drying and sun drying. The treatments were analyzed for proximate and mineral contents using...
