This study presents a combined pneumatic seed-metering device (SMD) that could not only fill, carry, and meter seeds, but also switch quickly between seed-metering and seed-cleaning modes, and clean seeds thoroughly and rapidly. The seed-filling, seed-carrying, and seed-metering modes of the SMD were analyzed based on a theoretical kinematic model. Furthermore, a three-factor, three-level ortho...

Reseeding is used to improve fault coverage of pseudorandom testing. The seed corresponds to the initial state of the LFSR before filling the scan chain. The number of deterministic seeds required is directly proportional to the tester storage or hardware overhead requirement. In this paper, we present an algorithm for seed ordering to minimize the number of seeds required to cover a set of det...

In this research, the historic data of NOAA /AVHRR NDVI (1981-2000) and the anomaly vegetation index were utilized. Monitoring and analyzing the winter wheat drought situation in the pre-green up period, green up period, heading period and filling period from 1997 to 2000 in Hebei province, Discussing the effects of drought situation in the key growing periods on the winter wheat yield, Taking ...

safflower as an original crop in iran has high adaptability to different environmental conditions. iran is one of the original areas of safflower as a drought and salinity tolerant crop. therefor, safflower can be a suitable alternative crop for cultivation in marginal areas. the aims of research were studying the late season drought effects on seed and oil yields and its components of fall saf...

abstract heterotrophic seedling growth has described as the product of the following dynamic and to transmit seed reserves and the conversion efficiency of mobilized seed reserves to seedling tissue. this research was carried out to evaluate germination and seedling growth of wheat seed (n8019) in the form of combined analysis design with crd arrangement. treatments consisted of 4 levels of wat...

Asparagine accounted for 50 to 70% of the nitrogen carried in translocatory channels serving fruit and seed of white lupin (Lupinus albus L.). Rates of supply of the amide always greatly exceeded its incorporation as such into protein. An asparaginase (l-asparagine amido hydrolase EC 3.5.1.1) was demonstrated in crude extracts of seeds. In vitro activity was up to 5 mumoles of aspartate formed ...

Abstract In plants, a fascinating set of post-fertilization events result in the development dispersal unit known as seed. During maturation phase, seeds accumulate storage reserves and acquire desiccation tolerance, followed by an increase seed vigour during drying. Physiological (or mass) maturity may be attributed to stage when maximum dry matter accumulation has occurred, marking end seed-f...

Experimental plant growth regulator compounds are expected to improve wheat grain yield by extending the duration of green leaf area and altering remobilization stored carbohydrates. In order evaluate this, materials supplied a commercial third party were applied Tatonka hard red winter during mid-grain fill development stage. Overall, crop productivity increased. Compared control treatment, tw...
