Discuss the changes in rural areas and their impact on gender. Is modernization and development the answer? Poverty is highly found in rural areas where there is a lack of education‚ healthcare‚ limits access of choices‚ and numerous challenges for its habitants. A major cause of poverty among India’s rural people is the lack of access to productive assets and financial resources as well as high levels of illiteracy. According to International Fund for Agricultural Development (IFAD) women in

I turned this paper in two days late‚ but the teacher was so impressed that I still got 100% Excellent; I couldn’ t have written a better paper myself. DIVERSITY OF PLANTS Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago‚ trees had evolved and formed forests‚ within which the diversification of vertebrates‚ insects‚ and fungi occurred. Roughly 266‚000 species of plants are now living. The two major groups of plants are the bryophytes and the

Laboratory 1 Grain Size Distribution – Sieve Analysis Introduction The grain size distribution is a representation of the approximate distribution of soil grain sizes for a soil. The sieve analysis‚ also called mechanical method‚ measures the dry mass of soil retained on each sieve in a stack of sieves‚ where the sieve opening sizes vary from the largest to smallest going from the top to the bottom of the stack. All the soil particles retained on a particular sieve will have an ‘intermediate size’ or

described quantitatively according to different soil mass of particles sizes. Percentage of soil sizes can be defined as the mass of soil retained on each sieve divided by total mass of soil sample. The percentage for a certain sieve size is defined as 100% minus the total percentage of all soil retained on the sieve. The percentage graph vs. sieve size is drawn on the semi-logarithm to obtain the soil grading curve. From the particle distribution graph‚ particles size like D10‚ D30‚ and D60 can be

The Enlightenment was a period of individualism‚ science‚ rationalism‚ and of the human right ’ to govern nature. Poets and authors focused on creating perfect pieces of literature‚ and hoped that by some means their work would be considered sublime ’. With the coming of the Industrial Revolution and the age of Romanticism‚ several poets such as Blake‚ Wordsworth‚ and Coleridge sought the sublime ’ within the realms of nature. The Romantics began to create a new model of poetry through focusing

(coefficient of uniformity and gradation) from particle-size distribution curve. Sieve analysis consists of shaking the sample through a set of sieves that have progressively smaller openings. To conduct a sieve analysis‚ samples are oven dried for at least 24 hours. The soil is placed and shaken through a stack of sieves with openings of decreasing size from top to bottom. The mass of particles retained in each sieve is determined. Results showed that the particle–size distribution curve of coarse
