no tillage systems can reduce operating costs, enhance soil organic matter, ameliorate soil structure and prevent environmental damage caused by stubble burning. however, the lack of an appropriate direct drill for the hardened soil of arid areas reduces adequate soil-seed contact and, thus, the system has shown contradictory results in past tests. developing a direct drill to place the seed an...

The objective of this study was to examine the effect of bottle and can openers, operating postures on flexion angles of the hand; muscles activities and subjective rating when opened bottle caps and cans. Twenty participants performed two-bottle uncapping and two can opening tasks with five bottles and can openers on two operating postures (i.e. standing and sitting postures). In addition, the...

An active-action seeding depth automatic control system was designed , with the purpose of effectively ensure consistency and stability when seeder is operated in field. Strain-gauge pressure sensor used system, which can detect force on tip furrow opener soil real time, proceed to next step judge change according signal. In order achieve depth, signal formation circuit will send a exceeds appr...

The mechanism of furrow opener-soil interaction plays an important role in analyzing the process no-till planting opener. In order to study disturbance effect opener on loam soil, firstly, three-dimensional model was established by using SolidWorks. Secondly, 3D discrete element EDEM software. Combined with indoor soil bin test bench and high-speed camera technology, micro-disturbance macro-dis...

The purpose of this study was to begin to describe the neural circuit within the abdominal ganglion that modulates renal functioning in Aplysia. We found that the previously described cholinergic neuron L10 and peptidergic left upper quadrant (LUQ) neurons have important roles in the control of the kidney. Cell L10 and a subset of the LUQ cells branch extensively within the kidney and send majo...

We observed fibers immunoreactive (IR) to serotonin (5-HT), the myomodulins (MMs), and FMRFamide on the I7-I10 complex in the marine mollusk Aplysia californica. The I7-I10 muscle complex, which produces radula opening, is innervated primarily by one motor neuron, B48. B48 is MM-IR and synthesizes authentic MM(A). When B48 is stimulated in a physiological manner, cAMP levels are increased in op...

The article is devoted to improving the winter wheat seeding technology. Choosing rational design of opener group enables placement crop seeds in a deeper moisty soil layer for their rapid germination with formation surface relief from furrows. Seeds are placed into furrows at optimal depth 4-5 cm and furrow slices formed by thrown out chisel-shaped openers compacted individual rollers each ope...

Pharmacological testing with apraclonidine eye drops induces a typical reversal of anisocoria in patients Horner’s syndrome. Moreover, was observed to have an elevating effect on the upper eyelid syndrome as well healthy subjects, which is thought be mediated by alpha-1 adrenergic receptors present Muller’s muscle. We aim quantitatively investigate position compared physiological based infrared...

One of the promising methods for improving uniformity seed distribution in soil is control grain flow by guiding elements openers. This creates favorable conditions flight seeds openers and when leaving them backwards, which equalizes speed, modulus, unit, improves their soil. The presence parameters was theoretically substantiated, gave development process controlling at exit from using elemen...
