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

ABSTRACT Ready-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 ...

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

ABSTRACT In 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...

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 suspected Dermat...

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

Introduction Cleanup 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 life (Chakrabarty et al., 2008). Although many of these chemicals are utilized or destroyed, a high percentage ...

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 mosquito will increase. It leads to a chanc...

Incourse   of   this   study,   four   research   question   were   raised   amo...

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 aspect lead...
