Milling is the mechanical process of removing material from a piece of stock through the use of a rapidly spinning circular milling tool in order to form some desired geometric shape. An important problem in computer-aided design and manufacturing is the automated generation of efficient milling plans for computerized numerically controlled (CNC) milling machines. Among the most common milling ...
Quality improvement of domestic milled rice is an urgent issue in sub-Saharan Africa (SSA) because cannot compete with imports the growing urban market. Past studies considered poor milling facilities to be a major factor leading inferior quality rice. However, even modern recently established SSA, not yet necessarily competitive imports. Thus, finding ways improve paddy remains important quest...
PART III of this volume discusses complementary strategies toward the rice Green Revolution in sub-Saharan Africa (SSA), including mechanization, irrigation, and marketing efforts to enhance demand for domestic rice. In Asia, population pressure on land high prices relative input induced farming intensification, while mechanization irrigation development boosted productivity. However, SSA, incr...
Paddy soils are classified as wetlands which play a vital role in climatic change and food production. Soil carbon (C), especially soil organic C (SOC), in paddy soils has been received considerable attention as of recent. However, considerably less attention has been given to soil inorganic carbon (SIC) in paddy soils and the relationship between SOC and SIC at interface between soil and the a...
Knowledge of the area and spatial distribution of paddy rice is important for assessment of food security, management of water resources, and estimation of greenhouse gas (methane) emissions. Paddy rice agriculture has expanded rapidly in northeastern China in the last decade, but there are no updated maps of paddy rice fields in the region. Existing algorithms for identifying paddy rice fields...
This study investigates percolation and seepage through the bunds of flat and terraced paddies. Field experiments were conducted in Hsin-Pu of Hsin-Chu County, Taiwan, to measure the soil water content of various types of bund. Measurements revealed that the soil was unsaturated along the sloped surface of the terrace. Experimental results also indicated that seepage face flow did not develop e...
Dissimilatory Fe(III) reduction is a universal process with irreplaceable biological and environmental importance in anoxic environments. Our knowledge about Fe(III) reduction predominantly comes from pure cultures of dissimilatory Fe(III) reducing bacteria (DFRB). The objective of this study was to compare the effects of glucose and a selection of short organic acids (citrate, succinate, pyruv...
The study of greenhouse gas emissions has become a global focus, but few studies have considered saline-alkali paddy fields. Gas samples and saline-alkali soil samples were collected during the green, tillering, booting, heading and grain filling stages. The emission fluxes of CO2, CH4, and N2O as well as the pH, soil soluble salt, available nitrogen, and soil organic carbon contents were detec...
In an agriculture field paddy is one of the major staple foods in the Asian countries like China, India, Indonesia, and Bangladesh etc. But paddy disease likes a Blast; Bacterial Leaf Blight; Rice tungro etc. stops the growth of the paddy trees. If the diseases are not detected at an early possible stage then there is a decrease in the production of paddy. In this paper a noble methodology i.e....
Background and Objectives: Musculoskeletal disorders and low quality of life are the most common problems among paddy farmers in the world. Paddy farmers are exposed to inappropriate postures, long working hours and stressful environmental conditions. The aim of this study was to compare different farming methods of rice cultivation (traditional and semi-modern) on the prevalence of musculoskel...
