In this article we describe the CEP package for compressing EPS files. It belongs to the public domain and was released at the GUST meeting in Bachotek, 1997. The amount of disk space occupied by bitmap graphics is a well-recognized problem. For example, a 300 dpi picture (A4) contains ca 8700000 pixels; assuming that each CMYK pixel occupies four bytes, one obtains ca 35MB of disk space needed...

The present study was carried out during 2020-21 with an aim to examine the production and post harvest losses of major oilseeds in Mungeli district Chhattisgarh state. study’s focus on two blocks that were carefully selected, namely Pathariya district. There 60 respondents overall, sample size made up 22, 18, 12, 8 marginal, small, medium, large farmers, respectively. A schedule for conducting...

This research was conducted at Borlaug Institute of South Asia (BISA) Pusa, Bihar to assess the losses in harvesting and threshing by manual methods for wheat maize. 5 farmers from 15 identified villages were selected Samastipur district assessing maize crop. A total 75 this study Kabargama Phulhara, Ajana, Gopalpur, Maniarpur, Rampura, Ladaura, Birsingpur, Kalyanpur, Akbarpur, Pratapur, Basude...

the existing studies of threshing process of combine harvesters adopt the assumption of constant mass, which is contradictory to the phenomenon of separation of grains and short stalks in actual threshing process. therefore, the characteristics of threshing and separation are not accurately described. aiming at this problem, this study established the tangential-longitudinal threshing and separ...

There are various designs of tools and equipment used for harvesting the crops and threshing it separately. Sickles, hand tools and reapers for grain crops and diggers for tuber crops and rhizomes, operated with different power sources are used. Combine harvesters, both tractor mounted and self-propelled, are being very widely used for different grain crops. Functional requirements and principl...

It is widely believed that hexaploid wheat originated via hybridization of hulled tetraploid emmer with Aegilops tauschii (genomes DD) and that the nascent hexaploid was spelt, from which free-threshing wheat evolved by mutations. To reassess the role of spelt in the evolution of Triticum aestivum, 4 disomic substitution lines of Ae. tauschii chromosome 2D in Chinese Spring wheat were developed...

Some mechanical and process parameters of a developed millet thresher have been optimized using numerical optimization technique. The machine threshes panicles cleans the grains from straw. speed threshing number pegs attached to drum were investigated, while moisture content was parameter under investigation. Threshing efficiency, cleaning percentage losses used as performance characteristics ...

Harvest and post-harvest operations constitute principal constraints to rice production, especially in irrigated systems, because of the larger yield that has to be handled. Post-harvest crop losses of up to 35% have been reported and attributed to inefficiency of manual threshing of rice by small-scale farmers. This leads to poor grain quality and rejection of locally produced rice. The Africa...

Wheat domestication from wild species involved mutations in the Q gene. The q allele (wild wheats) is associated with elongated spikes and hulled grains, whereas the mutant Q allele (domesticated wheats) confers subcompact spikes and free-threshing grains. Previous studies showed that Q encodes an AP2-like transcription factor, but the causal polymorphism of the domestication traits remained un...
