A ocupação de recursos alimentares por cupins pode ser modulada pela quantidade e qualidade do recurso. Aqui, avaliamos se o tipo de recurso interfere: (i) na proporção e velocidade de ocupação das iscas; (ii) no número de espécies que co-ocorrem e (iii) que particionam as iscas durante 53 dias. Diferentes tipos de iscas (papelão, papel higiênico, bagaço de cana-de-açúcar, tolete de cana-de-açúcar e esterco bovino) foram instalados durante a estação chuvosa, em área sem vegetação,...

Great Apes Plant Foods As Valuable Alternative Of Traditional Medicine In Congo Basin: The Case Of Non-Human Primate Bonobos (Pan Paniscus) Diet At Lomako Fauna Reserve, Democratic Republic Of The Congo

Koto-Te-Nyiwa Ngbolua
Great apes are a good model for human pathology and physiology. Great apes eat several plant species claimed by traditional healers to treat various ailments in folk medicine. Some of the items consumed by great apes have low nutritional value suggesting that health might be improved or regulated by such ingestion as previously postulated. Among the inventoried plant species known to be eaten by bonobos at Lomako Fauna Reserve, at least nine (30%) are used...

Gc Ms Analysis Of Polygonum Glabrum Leaf Petroleum Ether Extract

A.Doss
Polygonum glabarum has medicinal values; methanol leaf extract of this plant was analyzed using Gas Chromatography–Mass Spectrometry, while the mass spectra of the compounds found in the extract was matched with the National Institute of Standards and Technology (NIST) library. Gas chromatography mass spectrometry (GC-MS) analysis revealed the presence of 10 compounds. In GC-MS analysis, some of the phytocomponents screened were 3, 4-Bis (3, 4, 5-trimethoxyphenyl)-1-[2-(4-methoxyphenyl) ethyl] pyrrole-2, 5-dicarboxylic acid (98.57%), (2RS)-1,3,8-trimethyl-4-propyl-5-ethyl-2-(1-hydroxyethyl)–7–methoxy carbonyl ethyl –...

Cause Specific Infant Mortality In University Of Nigeria Teaching Hospital, Enugu: A Demographic Study

Chinelo Mercy Igwenagu
Cause specific death rate is the death as a result of a particular cause. It is essential for understanding the overall epidemiological profile of disease in a population over time. This paper has examined the cause specific infant mortality in University of Nigeria Teaching Hospital Enugu. In identifying the magnitude of all causes of death, correlation analysis result indicates that out of sixteen causes considered for the period under study, the significant causes were Septicemia,...

Assessment Of Adsorption Kinetics In A Quaternary Liquid Phase System Using Activated Carbon Derived From Oil Palm Empty Fruit Bunch

I. Olateju I.
A fixed mass of activated carbon as adsorbent was tested for the removal of organic pollutants (phenol, butanol, butan-2-ol and 2- methyl butan-2-ol) from an aqueous solution via batch adsorption experiment. The effect of the pollutants initial concentrations and contacting (agitation) time on pollutants adsorption was investigated. The purpose of the research is to determine the rate of adsorption (adsorption kinetics) of a quaternary system comprising of phenol, butanol, butan-2-ol and 2-methyl butan-2-ol, using activated...

Design And Implementation Of A Four Ways Or Junction Prototype Crossroad Traffic Light Control System

Oshevire Patrick
This paper is aimed at creating  prototype traffic light model using LED (Light Emitting Diode) since LEDs consume 80-90 percent less energy and generally last 5-7 years or longer compared to just a year for a incandescent light signal.LED are brighter, the LED arrays fill the entire “hole” and have equal brightness across the entire surface, making them brighter overall. It will also involves the use of a digital logic gate, multivibrator, IC (Integrated Circuit),...
