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

AbstractOne 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 bec...

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

ABSTRACTComparative 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 phy...

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

ABSTRACTThe 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 for...

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 ...

EFFECT OF ISONIAZID ON THE METABOLISM OF PARACETAMOL IN RATS

ABSTRACTThe metabolism of Paracetamol has been studied in Isoniazid pretreated albino rats and comparedwith 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 with120mg/5ml/kg body weight dose of Paracetamol interperitoneally. However, Groups II-V servedas test groups and the members were pretreated with 10mg/kg body weight dose of Isoniazidinterperitone...

THE CAMPUS AS A LEARNING SPACE: AN INFORMATION AND COMMUNICATION TECHNOLOGY EXPERIENCE

Abstract As  the  ownership  and  use  of  personal  technology  has  become  increasingly ubiquitous,  the  adoption  of  Information and  Communication Technology by higher education has continued to grow rapidly, with all Nigeria institutions integrating  technology  into  the  learning  experience.  Many  institutions  of higher education are creating learning spaces spe...

Utilization of E-Learning for Effective Teaching of Vocation

AbstractThe success of integrating Information and CommunicationTechnology into the educational system depends largely on the skill,knowledge, and manipulative competency level of the teacher in itsusage to the benefit of the learners. Therefore, this paper is focused onthe utilization of E-learning for effective teaching of vocationaleducation courses in Nigeria. It covered the concept of e-learning;concept of utilization of educational resources; teachers’ competencyand utilization of e-l...

MILLENNIUM DEVELOPMENT GOALS: THE ROLE OF TECHNICAL VOCATIONAL EDUCATION AND TRAINING

To this end, this paper focuses on Millennium Development Goals: Role of Technical VocationalEducation and Training. It discusses the concept of Technical Vocational Education and Training, indexes of development, technologyteachers’ roles in achieving the MDGs in area of poverty and hunger eradication, different co...

Development of a Geo-electrical Database Management System (GDBMS) for Geoscientist Application.

In the field of geosciences, large sum of data are always  acquired, processed and interpreted for different geographic locations, but only few of the data are well managed, such that, they can be useful for subsequent geoscience related surveys carried out in the same geographical locations. This is a challenge in the geoscience field, and it would be beneficial to the field when this challenge is resolved and it becomes a utilisable concept. It is in this regard tha...

Determinants of Child Mortality in Kenya: Stratified Cox Proportion Hazard Model

This study explores determinants of child mortality in Kenya using the 2008/09 Kenya demographic and health survey (2008/09 KDHS) data. Cox proportional hazard model is used and stratification method was used to handle the non-proportionality of the hazards. Kaplan Meir log rank test is used to explore the data and determine the significant variables that have association with child mortality to be used in the model.The study establishes that there is improvements in child survival...

Variations Iteration Method for Solving Delay Differential Equation/Numerical Analysis

ABSTRACT   A  powerful  and  effective  numerical  tool  called  the  Variational  Iteration Method  has  been  used  to  solve  various  kinds  of  differential  equations  over  the years. Though the Variational Iteration Method has not been used solely to solve various  kinds  of  differential  equations  as  it  has  always  been&n...

CHARACTERISATION OF ESSENTIAL OIL FROM LEAVES OF Euphorbia heterophylla AND ITS INSECT REPELLENT POTENTIAL

This study aimed at characterizing essential  oil  from leaves of  E.heterophylla and its insect repellent potential. Essential oil from fresh leaves of  E.heterophylla was extracted by  hydro distillation method, using a  Clevenger apparatus for 4 hours and the  yield was 0.1816%w/w. Repellence  test was conducted by  using 5 cockroaches in number which were  placed in a modified Y-tube Olfactometer and observations recorded for  each an...
