Table 1. Effect of paclobutrazol (paclo) on plant height and number of leaves developed on hollyhock at 2, 4, or 6 weeks after treatment. All application techniques were designed to deliver 0.10 mg paclo/10-cm Our objective was to determine the efficacy of a given dosage of β-[(4-chlorophenyl)methyl]-α-(1,1-dimethylethyl)-1H1,2,4-triazole-1-ethanol [paclobutrazol (paclo)] applied using differin...

Modal parameter analysis is a common method for structural characteristic analysis. To accurately identify the modal parameters that describe vibration characteristics of structure, chassis frame rice transplanter taken as research object. The least squares complex frequency domain method, admittance circle and peak picking are used to process measured signal. parameters, such natural frequency...

This study designed a cam-linked planetary gear system automatic seedling picking mechanism to address unstable operation and issues of high damage the substrate caused by dryland vegetable transplanter. Through an analysis kinematic principle structure establishment model, computer-aided software was developed using Visual Basic 6.0. Consequently, set structural parameter values satisfying tar...

In contrast to the usual inclusion of disulfide bonds within a polymer structure to facilitate bio-degradation, we have designed a self-curing "one pot" hyperbranched polymer capable of forming crosslinked gels under reducing conditions abundant in tumoural tissue.

China is the largest vegetable producer in world, and production more geographically concentrated Huang-Huai-Hai region Yangtze River Basin. There are significant challenges ahead for increasing average yields of vegetables this region. The effects a cultivation system, mulched ridge with double row (MRDR), were evaluated by using 2ZBX-2A transplanter newly designed paper. key parameters equipm...

Langmuir–Blodgett (LB) technique has been used to deposit composite multilayers of poly(3-octylthiophene) with cadmium arachidate (POT-CdA), zinc arachidate (POT-ZnA) and copper arachidate (POT-CuA). These composite multilayers were used as precursors to develop the respective semiconducting CdS, ZnS and Cu2S nanoclusters in the POT-arachidic acid (POT-AA) matrix. The formation of sulphide nano...

The total synthesis of the sialic acid-containing antigenic epitope fucose GM(1) (Fuc-GM(1)) by an improved reactivity-based one-pot synthetic strategy is reported. Based on a thioglycoside reactivity database, three saccharide building blocks, 3, 4, and 5, were designed and prepared to incorporate a descending order of reactivity toward thiophilic activation. Using the reactivity-based one-pot...

A gearbox is an essential component of automatic transplanter to transmit engine power the components. It necessary find appropriate dimensions and materials for pepper minimize transmission losses. Therefore, objectives this research were simulate efficiency gearbox, determine a suitable number stages, spur gears. 2.6 kW gasoline was considered as prime source entire transplanter. The availabl...
