A Preliminary Study on the Effect of Storage Period on Flavour Profile and Consumers’ Acceptability of Tsire, a Nigerian Stick Meat

Tsire is a popular Nigerian stick meat commonly produced by grilling of sliced and spicedbeef meat hanged on tips of sharpened sticks. The process of grilling initiatescharacteristic flavour development in the product, making it appealing to consumers.Unfortunately, sellers of the product do not usually exhaust their sales and product may beleft over till second day or more. This may adversely affect the flavour appeal andacceptability of the product. In the present study, the flavour compoun...

Numerical Solution of a One-Dimensional Second Order Macroscopic Traffic Flow Model with a Source Term.

The study of traffic models has given rise to many models with the aim of realistically determining the behavior of traffic. The dynamics of the macroscopic traffic flow is modeled by a partial differential equation, where the object of study is to determine the density of traffic flow. We derived a second order macroscopic traffic flow model equation from a first order one using the Fick’s law of diffusion. We formulated second order macroscopic traffic flow model equation with a sourc...

A Review on the Medicinal Uses of Sunflower (Helianthus Annuus) Oil

ABSTRACT Sunflower   (Helianthus   annuus  L.)   is   a   genus   of   plants   comprising   about   70 species. It is famous for its unique nature of heliotropism and is the world’s most important source of oil. Around the world, sunflower production is 31.1m tons,with more than 26 ha under sunflower cultivation. Sunflower stalks have been used as fuel, fodder for livestock, food for poultry, and ensilage. Sunflower seeds were and still are eaten raw, roasted, cooked, ...

EVALUATION OF THE SUPPRESSIVE EFFECT OF THE ESSENTIAL OIL OF TITHONIA DIVERSIFOLIA ON PLASMODIUM BERGHEI IN LABORATORY MICE

ABSTRACT The evaluation of the anti malarial properties of the essential oil extract of Tithoniadiversifolia was carried out using the standard tests suppressive tests in laboratorymice.   The   Swiss   albino   mice   were   infected   with   rodent   malaria   parasite(Plasmodium berghei berghei) and were treated with 300mg/kg, 600mg/kg and1200mg/kg   dose   of the   oil   extracts.   The  result   showed   that   the  oil  extract  ofTithonia divers...

Pathophysiology of Ebola virus

ABSTRACT  Ebola virus, a member of the Filoviridae virus family, is still an untamed, highly lethal viral pathogen that represents a nightmare for much of central Africa, which is the site of the majority of EBOV outbreaks (Geisbert et al.2010). Unfortunately there has not been a large push in the search for a vaccine as this virus, as deadly as it is, has not impacted a large portion of the world’s population with only 2,300 reported cases of hemmorraghic fever caused by filoviruses. On a...

ENHANCING MOBILITY CAPACITY AND NETWORK PERFORMANCE OF CLIENT-SERVER ARCHITECTURES USING MIPV6 HOST-BASED NETWORK PROTOCOL

  ABSTRACT A huge number of studies have been done supporting seamless mobility networks and mobile technologies over the years.  The recent innovations in mobile technologies have unveiled another revolution from the static architectural approach for client-server network relationships to more dynamic, and even mobile approaches. Due to the special equipment and infrastructure needed to support network mobility management, it is difficult to deploy such networks beyond the local network co...

Quantitative Model for Dynamic Propagation and Countermeasure of Malicious Cyber Attack on the Mobile Wireless Network

Abstract One major concern of network and data security consultants globally is the capabilities of infectious malicious cyber-attacks (Malware) to invade the entire population of the network terminals within few days of an outbreak of an attack to wreak havoc ranging from identity theft, financial fraud to systemic digital assault on critical national assets. It is known that when the vulnerable mobile device communicates with the infected nodes, it becomes infected. This work studi...

Computer Malware Propagation and Control

A major grief of network and data security experts and consultants universally is about the capabilities of infectious malicious proxies (Malware) to overrun the whole systems on networks stations in order to inflict mayhem encompassing identity theft, financial scam and systemic digital assault on infrastructures and national resources. In this work, we studied the interactions of two vulnerable classes with the infected and recovered terminals on the systems network and the active use of an...

COMPARATIVE ASSESSMENT OF PHYTOCHEMICAL CONTENT AND ANTIOXIDANT POTENTIAL OF Azadirachta indica AND Parquetina nigrescens LEAVES

ABSTRACT Comparative assessment of the phytochemical content and antioxidant potential of Azadirachta indica (neem) and Parquetina nigrescens (bullock) is the aim of this study. In order to achieve this, both plants were harvested from the botanical garden, University of Ibadan. The leaves were removed from the stem, washed with running water to remove contaminants, oven dried at 37˚C and milled into powder. The qualitative analyses of both plants were investigated after which six selected p...

Physico-Chemical and Antimicrobial Study of Hydro-Distilated Essential Oil Obtained from Nigerian Pepper (Capsicum frutescens)

Globally the industrial utilization of pepper is moving from the use of conventional powder to the extracts consequent upon their technical and economic benefits. Nigeria should not be left out of this global trend as a result of the enormous quantity of pepper extracts now used in the food industries.The antimicrobial activity of essential oil of Capsicum frutescens was assessed in this study. The physicochemical properties of essential oil obtained from fresh and dried pepper was carried ou...

Effects of Palm Oil Processing Waste on Soil

ABSTRACT The microbiological and physicochemical characteristics of soil receiving palm oil processing waste (POPW) in Abraka were investigated. The effect of palm oil processing waste was tested on loamy, sandy and clay soils. The pour plate technique was used for the isolation of the organisms. The total mean bacterial count ranged from 0.91±0.03log10CFU/g to 6.13±0.06log10CFU/g for loamy soil, 0.90±0.02log10CFU/g to 6.09±0.02log10CFU/g for sandy and 0.72±0.04 to 6.0±0.02log10CFU/g fo...

DESIGN AND IMPLEMENTATION OF A COMPUTER TROUBLESHOOTING INTELLIGENT SYSTEM

ABSTRACT Detection  of  personal  computer  (PC)  hardware  problems  is  a  complicated  process  which demands  high  level  of  knowledge  and  skills.    Depending  on  the  know-how  of  the  technician,  a simple  problem  could  take  hours  or  even  days  to  solve.  The aim  is  to  develop  an  expert  system for  troubleshooting  and  diagnosing  personal  computers  thereby  assisting  personal  computer owners  in  dealing  ...

EFFECT OF ISONIAZID ON THE METABOLISM OF PARACETAMOL IN RATS

ABSTRACT The metabolism of Paracetamol has been studied in Isoniazid pretreated albino rats and compared with control. During this study, thirty-five (35) laboratory albino rats were used divided into five (5) groups of seven (7) rats each. Group I served as control and the rats were only administered with 120mg/5ml/kg body weight dose of Paracetamol interperitoneally. However, Groups II-V served as test groups and the members were pretreated with 10mg/kg body weight dose of Isoniazid interpe...
