A Seminar Paper on Internet of Things (IoT)

ABSTRACT Internet of Things (IoT) is a concept that encompasses various objects and methods of communication to exchange information. Today IoT is more a descriptive term of a vision that everything should be connected to the internet. IoT will be fundamental in the future because the concept opens up opportunities for new services and new innovations. All objects will be connected and able to communicate with each other, while they operate in unprotected environments. This later as...

The Efficacy of Disinfectants on Candida albicans at Different Concentrations and Contact Times

ABSTRACT The upsurge of Candida albicans as the fourth most common causative agent of nosocomial infections necessitated the evaluation of a range of disinfectants for their efficacy against this organism. This project work was designed to basically determine the anti-Candida efficacy of three commonly used, commercially available disinfectants, namely Savlon, Septol, and Izal, using suspension test technique. The test organism was challenged with various concentrations (25%, 50%, 7...

Bactericidal Activities of Hibiscus Sabdarifa Leave Extract against enteric human pathogens

Microbiological  tests  revealed  that  Hibiscus  sabdariffa  plant  extract  has  antibacterial properties  thus  verifying  folklore  medicine  in  the  treatment  of  abscesses,  bilious  conditions, cough,  dysuria  and  scurvy  (Morton,  1987;  Perry,  1980  Ross,  2003).  The  extraction  type  of aqueous  generally  had  the  same  potency  with  cold  extracts  having  a  slightly  better antimicrobial  activity  than  hot  aqueous  ex...

Characterising Growth Behaviour of Yeast Strains Isolated from Mango Fruit in Carbon, Nitrogen and Stress Environments

ABSTRACTThe present experiment aims at investigating the growth behaviour of different yeast strains inselected carbon, nitrogen and stress environment to obtain strains with prospects for industrialapplication.   Specifically,   the   study   is   set   to:   isolate   yeast   from   decaying   mango   fruit   anddetermine growth performance of yeast strains in different environments, carbon, nitrogen andstressors. The procedure adopted in the study uses different y...

Bacterial Bioluminescence - A General overview

Bioluminescence is the process by which certain living organisms produce light through a seriesof enzymatically   catalyzed  biochemical reactions  (Brodl  et al., 2018). Any organism   that iscapable of exhibiting or carrying out bioluminescence is termed a  bioluminescent organism.Bioluminescence is a phenomenon that has been found in almost all branches of the evolutionarytree   (Tyulkova  et   al.,   2009),  &...

Life Expectancy and Lethal Effect of Culex Quinquefasciatus Larvae due to S-Hydroprene and Leaf Extracts of Azadirachta Indica

AbstractCulex quinquefasciatus is a dorminant mosquito species in Nigeria and a major cause of several diseases. The study seeks to determine the effects of S-Hydroprene and leaf extracts of Azadirachta indica on life expectancy of third instar larvae of Culex quinquefasciatus. Concentrations (ranging from 10 mg/L to 60 mg/L) were tested on the larvae for mortality, survival and life expectancy of the medically important Cx. quinquefasciatus mosquito species under laboratory conditions of tem...

SYNTHESIS OF NANOCELLULOSES AND CHARACTERIZATION

Nanocellulose prepared from the natural material has a promising wide range of opportunities to obtain the superior material properties towards various end-products. In this study, commercially available natural cotton was treated with aqueous sodium hydroxide solution to eliminate the hemicellulose and lignin, then cellulose was collected. The collected cellulose was subjected to acid hydrolysis using sulphuric acid to obtain nanocellulose. The prepared nanocellulose was further characterize...

CELLULOSE COMPOSITE OF TREATMENT

Cellulose water treatment are naturally occurring with unique structural, mechanical and optical properties. While the paper and packaging, automotive, personal care, construction, and textiles industries have recognized cellulose water treatments’ potential, we suggest cellulose water treatments have great untapped potential in water treatment technologies. In this review, we gather evidence of cellulose water treatment s’ beneficial role in environmental remediation and membranes for wa...

EFFECTIVE ROLES OF FUNCTIONAL FOODS AND NUTRACEUTICALS IN MANAGEMENT AND TREATMENT OF CANCER IN AFRICA: AN INSIGHT INTO ITS THERAPEUTIC AVENUES AND POSSIBLE DEVELOPMENT AS FUTURE NUTRACEUTICA

ABSTRACT  Cancer they say is the chief of all maladies, following cardiovascular disease, cancer is the second leading cause of death in most affluent countries. There are about 13.3 million new cases of cancer in 2010 which is predicted to cost US$ 290 billion, but the total costs is expected to increases to US$ 458 billion in the year 2030 on basis of World  Economic  Forum  in  2011.  More  than  half  of  all  cancer  cases&...

ANTIBACTERIAL AND PHYTOCHEMICAL PROPERTIES OF STEM BARK EXTRACT OF Mangifera indica (Linnaeus)

ABSTRACTIn African folk medicine, water infusion of Mangifera indica stem bark are highly valued in thelocal treatment of malaria fever, diarrohea, diabetes mellitus and liver diseases. Various part ofthis   plant   can  also  be   used   in  treatment   of   toothache,  dysentery,  anemia,   hypertension   andinsomnia in different parts of the world. This study was described to determine ...

Evaluation of Oxytocic Potential of Methanol Extracted sida acuta on Female Albino Rats

ABSTRACTPlants have long been a source of nutrition and therapy to man. The medicinal value of these plants lies in some chemical substances that produce a definite physiological action in the human body. This study evaluated the oxytocic potential of methanol extract of Sida acuta on female albino rats in vitro. Oxytocin was used as a standard drug though it is a biochemically synthesized hormone that act on distant hormone receptor to induce contractions. The methanol extract was prepared u...

DETERMINATION OF VISCOSITIES OF SOME SELECTED LIQUIDS USING STOKE’S METHOD

ABSTRACTViscosity is a property of a liquid and is defined as the resistance of a liquid toflow. This research is to determine the viscosities of motor oils (10w – 40w, 20w –50w), vegetable oil and honey using the fall sphere method. The viscosity of honeywith 4.44Ns/m2was found to be the highest and that of vegetable oil having a valueof 0.002861Ns/m2  is termed the lowest. The viscosities of motor oils (20W-50W )and (10W-40W) were found to be 0.00468Ns/m2  and 0.00374Ns/m2  respectiv...
