Generation of bioethanol from common date by-products, “Teggaza and Lebghel” in Southern Algeria

Date by-products constitute the principal food for the oasis populations in Middle East and North Africa. Dates contents consist of 70 to 80% of reducing sugars, and do not require an intensive energy and labour for thermophysical pre-treatment. They can serve as a good feedstock for bioethanol generation through fermentation and distillation. Algeria is among the top sixth producers of dates in the world with more than 250,000 tons/year; from these, more than 30% can be lost for dif...

Phenolics Comparison between Twinning and Celestial Peppermint Teas using HPLC-DAD

Abstract Twinings and Celestial pure peppermint herbal tea is made from 100% select peppermint leaves and is naturally caffeine and gluten-free and parts of their differences lie in the packaging. The HPLC profile of Twinning peppermint and celestial peppermint teas showed that both the teas samples contain caffeic acid, ellagic acid, pcoumaric acid, rosmarinic acid and rutin while celestial peppermint tea had an extra phenolic compound called quercetin. Quercetin was known for its anti-i...

ACTIVATION OF CASPASE ACTIVITY IN RAT LIVER CELLS BY METHANOL EXTRACT OF GLORIOSA SUPERBA

Activation of caspase 3&9 by methanol extract of Gloriosa superba  ABSTRACT Mitochondrion is the key regulator in cellular energy homeostasis and plays a central role in determining cell apoptotic process; it is therefore regarded as a vital target for cancer chemotherapy. Cancer is obviously one of the most common areas where demand for alternative treatment is overwhelming. Many investigations revealed that bioactive compounds in natural products can act on mitochondria to trigger the per...

Caspase activation by methanol extract of Gloriosa superba on rat liver cells

Methanol extract of Gloriosa superba in this research was adopted due to the presence of photochemicals present in the plant. This photochemicals are known to act as antioxidants and anti tumor agent but it is not yet known if the activity of the plant is through the mitochondria mediated pathway, caspase activation and induction of apoptosis where up regulation is necessary 

PHYTOCHEMICAL SCREENING AND ANTIBACTERIAL ACTIVITY OF CRUDE ROOT AND STEM BARK OF Lannea acida

                ABSTRACT Lannea acida is a plant known to have various medicinal and therapeutic properties. The  phytochemicals or secondary metabolites and antibacterial activity of its root and stem bark were  studied in this research work. The phytochemical screening of the plant was carried out using  standard methods of analysis and these investigations revealed the presence of bioactive  components comprising flavonoids, alkaloids, saponins, steroids, terpenoids, gly...

Maternal vitamin A supplementation delays time to first episode of parasitaemia and reduces malaria parasite densities among infants in rural communities in Ebonyi State, Nigeria

The study was a randomized mother –infant dyad placebo controlled field trial that evaluated the effect of maternal vitamin A supplementation on time to first episode of parasitaemia and on malaria parasite densities among infants in three rural communities in Ebonyi State, Nigeria. One hundred and fifty-two (152) pregnant women with pregnancies that had mature to at least six (6) months were equally randomized into supplemented and placebo groups. Ten thousand international unit (10,0...

A COMPARATIVE STUDY OF THE FUNCTIONAL PROPERTIES OF FLOURS FROM THREE VARIETIES OF SWEET POTATO (Ipomoeas batatas) ROOTS

ABSTRACT This study was undertaken to assess the functional properties of flours from three varieties of sweet potato (Ipomoeas batatas). The varieties used in this study include orange flesh sweet potato – ‘Umuspo – 3 (Mother’s Delight)’, cream flesh sweet potato – ‘Ex-igbarium’ and red skin-white flesh sweet potato varieties. The functional properties analysed include Swelling power, Water absorption capacity, Oil absorption capacity, Bulk density and least gelation capacity...

Background: African locust bean is a condiment believed to be for the people of low class. Itshealth importance has not been fully known especially to the so-called high class.Aim: This study is aimed at investigating the effect of African locust bean on fasting blood sugar andlipid profile of albino rats.Methods: African locust bean (ALB) was purchased from a local market at Orita-Challenge area ofIbadan, Nigeria. They were sun dried and milled into powder using an electronic blender. Thepow...

USE OF OPEN SOURCE APPLICATIONS IN HIGHER LEARNING BY PROSPECTIVE COMPUTER SCIENCE TEACHERS IN ABUBAKAR TAFAWA BALEWA UNIVERSITY, BAUCHI

Abstract This study investigated the use of open source application in higher learning by prospective computer teachers. Colleges and universities are increasingly aware of the necessity to use technology to meet both the business and academic mission of the institution. Often, open source software (OSS) and Free Source Software (FSS) are seen as viable options for meeting these challenges. Many Institutions are recognizing the importance of the interplay or overlap between FSS and OSS as...

Toxicological Effect of Monosodium Glutamate in Seasoning on Human Health

The use of seasonings to enhance the flavor of food has been on the increase in recent time. Different types of seasonings are produced daily. Theconstituent of these flavor-enhancers is unknown to ignorant consumers. They only want to eat food with good taste without consideration of theeffect of these additives on their health. These seasonings contain monosodium glutamate (MSG) which really spiced the food. This review focuses onthe toxicological effect of monosodium glutamate in seasoning...

Quality Assessment of Sachet and Bottled Water in Ogbomoso Metropolis, Nigeria

Background: Access to potable water has become a difficult task in many countries of the worldincluding Nigeria. In Nigeria, the government is trying her best to make water supply available tothe masses but till now this vision has never been accomplished. If those living in urban areascould not have access to portable water supply by the government, what is the fate of the peopleliving in rural areas? This has led to increased usage of sachet and bottled water as portabledrinking water.Aim: ...

Adsorption efficiency of coconut husk for removal of Rhodamine-B dye from aqueous solution

ABSTRACT The efficiency of acid modified locust bean pod (ALBP) as low cost adsorbent to remove  Rhodamine-B (Rh-B) dye from aqueous solution was studied. The morphology, functional groups and  elemental analysis of the adsorbent were investigated by SEM, FTIR, pH (pzc), and Boehm titration analytical techniques. Operational parameters such as contact time, initial dye concentration and solution temperature  were investigated. The amount of Rh-B dye adsorbed was found to increase as these ...

A GEOELECTRIC SURVEY OF UNDERGROUNDWATER AT AL-QALAM UNIVERSITY KATSINA CLINIC USING VERTICAL ELECTRICAL SOUNDING
