ATTENDANCE MANAGEMENT SYSTEM OF STAFF IN AN ORGANISATION

AbstractAttendance management is the act of managing attendance or presence in a work setting, which maximises and motivates staff attendance thereby minimising loss. Not only does it affect productivity, it can cost the organisation profits or even additional contracts. For the industrial sector attendance management system can develop alacrity among the workers to work regularly and also help them to motivate their co- worker to attend work regularly. Fingerprints are consid...

In Vitro Antioxidant Activity and Nitric Oxide Scavenging Activity on Citrullus Lanatus Seeds

Citrullus lanatus (water melon) is a commonly consumed fruit worldwide. The seeds are often thrown away without considering its potential nutritional and medicinal benefits. In this study, a methanol extract of citrullus lanatus seeds was analyzed for the presence of bioactive secondary metabolites and to determine its ability to scavenge 2, 2‐ diphenyl ‐1‐ picrylhydrazyl (DPPH.) radical, superoxide anion radical (O2.‐), and nitric oxide radical (NO.). Quantitative phytochemical a...

Provenance and Tectonic Setting of Amasiri Sandstone (Turonian) in Ugep Area, Southern Benue Trough, Nigeria: Evidences from Petrography and Geochemistry

bstract -The petrographic and geochemical study of sandstones of Eze-Aku Formation (Turonian) outcropping in Ugep area southern Benue Trough Nigeria was carried out to ascertain the sandstone provenance and tectonic setting. Field studies show that the sandones occur in linear, parallel northeast-southwest trending ridges alternating with shale sequence. The sandstone facies showcoarsening upward sequence, slightly bioturbated, cross-stratified, rippled bedded which infer foreshore to shallow...

Reviewing Cyber-attack Incidents and Their Impacts on Global Oil and Gas Infrastructures: A Nigerian Perspective

ABSTRACTOil and Gas sector includes the exploration, gathering, production, processing, storage, and transportation of petroleum liquids and natural gas. With the oil and gas sector fueling every aspect of our daily life, the protection of its critical infrastructure is crucial. It is known that digitally connected oil and gas operations help to improve production (General Electric, 2018). So, in order to sustain uninterrupted energy production and for quick recovery from major cyber incident...

Effect of EDTA on Tomatoes Plants Seedlings Under Nickel Toxicity

CHAPTER ONE1.0 INTRODUCTION 1.1     NICKEL1.1.1  Occurrence         Nickel (Ni) is a metallic element,with atomic number 28; atomic weight 58.69. Is a metal, which belongs to group VIIIB of the periodic table. The most important oxidation state of nickel is +2, although the +3 and +4 oxidation states are also known (Tundermann et al., 2005). Nickel resembles iron, cobalt, and copper in its chemical properties. However, unlike cobalt and iron, ...

RELEASE KINETICS OF CYMBOPOGON CITRATUS ESSENTIAL OIL FROM STARCH BEADS

ABSTRACT The essential oil of Cymbopogon citratus was extracted using a green method (i.e. essential oil still), encapsulated into cassava starch matrix using sodium alginate as a binder. The encapsulated sodium alginate starch beads were characterized using Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectrophotometer (FTIR), release kinetics of the oil was monitored by UV-Visible Spectrophotometry from two (2) aqueous media, buffer of pH 4 and pH 9. The re...

NOVEL CHEMOTHERAPEUTIC TARGETS FOR THE CONTROL OF SCHISTOSOMIASIS

ABSTRACT      Schistosomiasis is a water-borne parasitic disease caused by schistosomes and transmitted by fully aquatic or amphibious freshwater snails in whose bodies the human-infective larvae, cercariae, develop. Adult schistosome worms colonise human blood vessels for years, successfully evading the immune system while excreting hundreds to thousands of eggs daily, which must either leave the body in excreta and/or urine or become trapped in nearby tissues. Trapped eggs ...

Application of mycology in forensic science

Abstract Forensic Mycology is the application of Mycology for producing evidence in terms of criminal investigation and their further evaluation in the court of law. The problem with relative neglect of Mycology in Forensic science is currently leading to insufficient knowledge, in order to support the needs for fungal expertise in areas of criminal investigation. Mucor hiemalis and Penicillium griseofulvum had been used to determine the minimum interval since death, Coprinus comatu...

MICROBIOLOGICAL EFFECT OF FERMENTATION ON THE NUTRIENT, ANTINUTRIENTS AND FUNCTIONAL PROPERTIES OF FERMENTED LIMA BEANS SEEDS (Phaseolus lunatus).

ABSTRACT Semi- solid raw Lima beans (Phaseolus lunatus) were fermented for a period of ten days, chemical (proximate composition, antinutritional contents, pH, and total titratable acidity) and physical changes (temperature, odour, and texture) occurring during the fermentation of the lima beans were monitored. The fermentation was carried out for 48, 96, 120, 168 and 192 hours respectively at ambient temperature. The microbial load was as well monitored. Microorganisms isolated fr...

Fingereye: improvising security and optimizing ATM transaction time based on iris-scan authentication

The  tumultuous  increase  in  ATM  attacks  using  eavesdropping,  shoulder-surfing,  has  risen  great  concerns.  Attackers  often  target  the  authentication stage where a customer may be entering his login information on the ATM and  thus  use  direct  observation  techniques  by looking  over the  customer's shoulder to steal his passwords. Existing authenticatio...

NETWORK BASED SECURITY INFORMATION SYSTEM

CHAPTER ONEINTRODUCTION1.1    IntroductionSecurity on the Internet and on Local Area Networks is now at the forefront of computer network related issues.  The  evolution  of  networking  and  the  Internet,  the  threats   to   information   and   networks   have   risen   dramatically.   Many   of   these   threats   have   become   cleverly    exercised    attacks    causing    damage    or    committing   theft.   The   Internet   ...

Design and implementation of a Simple word processor

CHAPTER ONEINTRODUCTION1.1 BACKGROUND OF THE STUDY The importance of computer cannot be over emphasized with respect to designing and implementation in text editing package which could be in sciences, engineering, business or government etc.  Consequently, computers are becoming indispensable. This is obviously true in developed countries; like Nigeria is gradually being gravitated into computer oriented society with professional engineers, analyst, design and implementation of...
