Expected impacts of active mining on the distribution of heavy metals in soils around Iludun-Oro and its environs, Southwestern Nigeria

This present study is aimed at evaluating the level of environmental degradation and potential ecological risk in soils around an active (tantalum-niobium) mining site of Iludun-Oro, southwestern Nigeria. A total of 18 topsoil samples were randomly collected from different parts of the study area and analysed using the inductively coupled plasma-mass spectrophotometry. The concentrations of Pb, Zn, Fe, Cu, Cr and Ni varied between 0–678, 7–222, 1.64–8.87, 8.8–145, 1.4–81 and 1.6–9...

Comparative study of the common protozoan parasites of 𝘊𝘭𝘢𝘳𝘪𝘢𝘴 𝘨𝘢𝘳𝘪𝘦𝘱𝘪𝘯𝘶𝘴 (African catfish) from wild and cultured environments in Bauchi metropolis

This project work studied and compared the common protozoan parasites of Africa cat fish (Clarias gariepinus) from wild and cultured environment within Bauchi metropolis, a total of 48 samples of C. gariepinus comprising 24 each from both wild and cultured environment were examined for protozoan parasites and only 18 and 13 fishes were infected by protozoa parasites respectively. Ichthyophthirus multifiilis was the most common protozoan parasites found in C. gariepinus from the wild and Trich...

Determination of Minimum Data Set for Vegetable Fields under Biofertilizer-fortified Compost Farming in Southwestern Nigeria

This  study  discovered  that  infiltration  rate,  bulk  density, pH  and  available  phosphorous  were  the  most  sensitive  soil properties  for  use  as  MDS  indicators for vegetable fields at south western of Nigeria. The    study    also    revealed    that    both    the  MDS indicators  and  SQI  value  obtained  were  influenced  by biofertilzer-fortified  compost  application and would  serve  as vital  instrument for evaluating soil fe...

Phytohormone Biosynthesis by Indigenous Rhizobacteria of Vegetable Crops in a Semi-arid Agro-environment

This      study      discovered      indigenous      rhizobacteria (A. brasiliense,  A. chrocoocum,  P. stutzeri  and  P. putida)  from the  rhizosphere  of  vegetable crops in semi-arid agro-zone of Rajasthan desert capable of synthesizing phytohormone. This study   will provide baseline information on the phytohormone biosynthesis    profile    of    t he    isolates    and    the phytohormone produced can be transformed into commercial bio-formulations  f...

Arbuscular Mycorrhizal Fungi Associated with Rhizosphere of Tomato Grown in Arid and Semi-arid Regions of Indian Desert

This  study  provides  knowledge  on  the  diversity  and drivers  of  AMF  in  the  ecologically  stressed  ecosystem  of  arid and  semi-arid  regions  of  Indian  desert  and  reveals  promising findings  that  would  provide  baseline  information  for  a  better understanding  of  more  important  roles  that  AMF  plays  in enhancing  resource  allocation  and  increasing  tolerance  of tomato plant to the  various  environmental  stresse...

Bio-filmed Bio-fertilizers and Organic Manure Application forReducing Chemical Fertilizer in Sustainable Okra production

The  study  justifies potentials  of  fungalbacterial  biofilm  bio-fertilizers  (FBBs)  and  organic  manure application  as  sustainable  means  of  improving  growth  and yield of okra, optimizing economics of production by reducing amount  of  chemical  fertilizer  application  and  minimizing  its deleterious  effects  on  environment,  soil  and  human  health. Appropriate  adoption  of  these  findings  by  farmers  and researchers  would  go  a...

Bio-burdens of some selected Fruits and Vegetables consumed within Katsina metropolis in KatsinaState, Nigeria

ABSTRACTReady-to-eat vegetables and fruits have intrinsic properties predisposing them to microbial contamination especially in the absenceof proper quality control procedures. Recently, the increased in consumables bio-burden manifested as the accumulation of potentialpathogenic microbes therein which triggered the food related ailments associated with morbidity and mortality cases. Evaluating themicrobial quality of such foods is therefore important. This study was aimed at evaluating the p...

Utilisation of Internet by Students of the Faculty of Technical Education at the University of Education, Winneba, Kumasi Campus

ABSTRACTIn this research, majority of the students use mobile phones (smart phones)/laptops thus 55(40.44%) with 53(38.97%) using their smart phones as the main device for accessing the internet. The respondents also confirmed the internet has helped significantly improved their academic work or studies generally with all 136(100%) saying yes to the question with 131 students using the internet on a daily basis. 63 and 32 of the students spend averagely 1-5hours and 6-10hours on the n...

Prevalence of Dermatophytosis Among Primary School Children at Wuntin Dada Primary School Bauchi

DERMATOPHYTE are unique of fungi that effect the Keratinous tissues of lower animals and human Dermatophytoses is the medical term for fungal infection of the superficial layer of the skin, nail, hair and scalp.  The prevalence study Dermatophytoses in Wuntin Dada Primary School Bauchi is to determine the prevalence of the diseases, the different clinical types and actual species responsible for the infections.  Out of 950 pupils examined, 105 children were found to be with s...

Biostimulatory Effect of Processed Sewage Sludge in the Bioremediation of Herbicide Polluted Soil

IntroductionCleanup   of   herbicide   contaminated   soils   has   been   a   dire   environmental concern since the advent of industrial era (Ramdas and Gerald, 2011). The rapid increase in population worldwide has resulted in the need for greater fuel demand and   development   of   industrial   chemicals,   fertilizers,   pesticides   and pharmaceuticals to sustain and improve quality of li...

Pagano's theorem. A generalized form of the Dirichlet integral involving Laplace Transforms techniques

The problem of integration technique over integrands of the form f(t)/t^n, can be solved by differentiation(n times)  by using Leibniz's rule to get rid of t^n, that leads to integrate back (n times) to end the game which it's harder than the original problem.This work focuses on the derivation of the formula (Pagano's Theorem) which is a perfect tool to avoid that hard task. It allows to change the difficult n iterated integrals  into a more outstanding easier problem which consists of n -...

Malaria-A climate Sensitive Disease

Abstract                 Every year thousands of people died due to malarial infection, mainly in developingcountries and under developed countries. In most of these places, the infected persons ‘age isbelow five and pregnant women are also affected by  malaria, this is due to weak and poorimmunity.  Another important reason is lack of awareness about malarial infection. In future, dueto climatic change, disease spreading population of ...
