A decorticating machine for Prosopis Africana was developed, tested and evaluated. Prosopis Africana is popular in the Sub-Saharan Africa, with all the parts of the tree useful for medicinal purposes. This study focuses on the threshing of the pod to obtain the seed, which is the most widely used of the parts of the Prosopis Africana tree. Results from preliminary investigations carried out of ...

this study was conducted during two years (2007-2009) in shawoor agricultural research station on a silty-clay soil. experiment conducted in split plots in a randomized complete blocks design in three replications. main plots were planting methods including centrifugal broadcaster (p1), centrifugal broadcaster + furrower (p2), seed drill (p3), seed drill + furrower (p4), three lines bed drillin...

In this paper, we describe an ongoing research to develop an HPSGbased treebank for Persian. To this aim, we use a bootstrapping approach for the data annotation. In the rst step, a set of seed rules are de ned as regular expressions in the CLaRK system. Then, the data is shallow processed with this set of rules. In the next step, a human annotator completes the annotation of sentences manually...

We present a fast, interactive method for separating bones that have been collectively segmented from a CT volume. Given user-provided seed points, the method computes the separation as a multi-way cut on a weighted graph constructed from the binary, segmented volume. By properly designing and weighting the graph, we show that the resulting cut can accurately be placed at bone-interfaces using ...

Date grading is an important process for producers and affects the fruit quality evaluation and export market. However, the high costs, low speed and variation associated with manual sorting have been forcing the post harvest industry to apply mechanization and automation in sorting operations. As a step toward mechanized grading, in this research Mamdani fuzzy inference system was applied as a...

In the paper, the necessity of root stubble harvesting and recycling was put forward from the perspective of biomass energy utilization. To accomplish mechanized harvesting on root stubble, a rotary digging machine was designed based on parametric modeling software Solidworks. Firstly, parts were built under entity modeling module, and then assembled to 4 main mechanisms in assembling environme...

Material Handling Equipment (MHE) is widely used to move packaged goods from manufacturing to warehousing, storage, transportation, in both warehouses and distribution centers to retail stores. Moving product between facilities is done by different types of equipment ranging from manually pushed carts to automated vehi­ cles. A considerable amount of research has been conducted to eval­ uate th...

the nutritional value of cereal straw can be increased using urea treatments as a source of ammonia. the conventional urea treatment process for cereal straw is a laborious and time-consuming task. it is essential to facilitate or eliminate part of the procedure with the use of machinery. this study examines the mechanical urea treatment of wheat straw and compares chemical components and diges...

Studies in African countries have shown an association between irrigation projects and the spread of schistosomiasis mansoni and haematobium. The aim of this study was to investigate the potential association between irrigation levels and the occurrence and spread of Schistosoma mansoni infection in the State of Bahia. Two forms of irrigation were developed in the State of Bahia: the first is c...
