message was that those who use a KingArmstrongmethod should standardize it by the manual method of King and Wootton (1956). Although most clinical chemists in the United Kingdom still use either a manual or mechanized King-Armstrong method, little help was offered to the increasing numbers of clinical chemists using either ,B-glycerophosphate or pnitrophenol phosphate as substrate. The relative...

Fine grain products are harvested in two manual and mechanized forms. Nowadays, common combine harvesters are used, but fine grain products such as Rapeseed, Sesame and Sorghum cannot be harvested with conventional heads of combine harvesters due to the excessive grain loss in the head of the combine. Therefore, the necessity of design and fabricating machines and heads of combine harvesters be...

A new homogeneous immunoassay (EMIT) for valproic acid was evaluated. Besides testing the manual version of this enzyme immunoassay, we also developed two mechanized procedures for centrifugal analyzers (the CentrifiChem and the COBAS system), which take less time and are more precise than the manual method. Within-assay precision (CV) was 4.5% with the manual technique and 2% with the analyzer...

Currently, maize production in China suffers from many problems, such as excessive fertilizer application, inefficient use, and insufficient agricultural labour. The effect of one-time mechanical point-applied fertilization controlled-release compound the root-zone on yield nutrient uptake was investigated to explore efficient patterns for decrease increase maize. selected a granular (24-6-10 N...

It is commonly accepted that tree form has an impact on the productivity of single-grip harvesters. However, it remains unclear, which elements of tree form are significant and to what degree they impact harvesting productivity. This is of particular importance in hardwood dominated stands, where hardwood trees often exhibit complex and variable stem and crown architecture that can complicate a...

We evaluated a new enzymatic kit for serum triglycerides (triacylglycerols) in two laboratories. The procedure involved both enzymatic hydrolysis of the triglycerides and conversion of the glycerol, which was linked to an indicator reaction. There was excellent agreement with the mechanized procedure of Kessler and Lederer and with a manual method. The test requires 50 mul of serum and can be c...

In order to determine the optimum rate of Vigna sun-hum seed sowing for rangeland rehabilitation in sandy soil of North Kordofan, Sudan, two trials were conducted separately under managed and unmanaged conditions at El-obeid Agricultural Research Farm in Sheikan locality of North Kordofan State in 2015 and 2016. Seed rates were 1, 2, 3, 4 and 5 Kg/feddan (4200m) and arranged by a Completely Ran...

The mechanized seed production of hybrid rice (Oryza sativa L.) represents significant progress in modern agriculture. However, the technologies and crop management strategies are still immature. present study was conducted with three field experiments to explore effects different planting densities, flight height an agricultural unmanned aerial vehicle (AUAV) for assisting pollination, fertili...
