The treatment of choice for a In this article, we find the necessary and sufficient condition under which the (α,β)-metric F=c_1 α+c_2 β+β^2/α; c_2≠0 is projectively related to a Kropina metric on a manifold M of dimension n ≥ 3, where α and α ̅ are two Riemannian metrics, β and β ̅ are two non zero 1-forms.

Background: Over the last few years, the notion that dyslexia is a learning disability, which initially appears as a difficulty in reading learning and later as unstable in spelled writing and as a lack of ability to manipulate written words in opposed to oral speech. The situation is essentially cognitive and usually genetic. It is not due to a mental deficiency, a lack of socio-cultural opportunity, emotional factors, or another brain building deficit. A large proportion of children with dyslexia are experiencing motor difficulties such as developmental coordination disorder.

The present study aims to explore whether there are gender-oriented differences in learners' performance when solving equations which require the application of a structure sense. In mathematics one can identify that learners lack a competence of logical observation of algebraic expressions. This deficiency results in the learners' technical approach to exercises, the time they require for obtaining the solution, numerous errors and difficulty in finding the solution. This absent competence is called 'the structure sense'.

Mulberry gardens are being contaminated by various pesticides and fungicides from nearby agricultural practice. Specifically copper containing fungicides utilized in adjacent cultivations where thecrops is being protected by copper fungicides to control the fungal pathogens. Copper besides other heavy metals and pesticides can also alters the activities of ATPase’s of silkworm larvae particularly sodium/potassium, magnesium, and total ATPase’s. Hence the author aimed to study the effect of copper on silkworm ATPase’s activity.
