As a result, it became necessary enhance current manufacturing system in addition impressing with its There is tendency for fruit trees be planted more densely or meadow orchards control size, keep desired architecture, and make operations like pruning, pest control, ha...
FETSWCM-SWAN and DualSPHysics models are used to study the storm flooding process of Dazuo Seawall in Quanzhou city, Fujian province, China. Firstly, a over-topping assessment method is proposed. Secondly, water level wave at foot calculated by during Typhoon Usagi 2013 Dujuan 2015. Finally, typical run-up processes modeled DualSPHysics. The results show that less than 2 m, but can reach 6.85 m...

Hence, suitability operations refinery processes by considering twenty different types Nigerian crude oil for assay analysis classification using Aspen Hysys. The re...
Introduction: Estrogen and progesterone are supposed to modify pain sensitivity. However, the actual role of each of these steroid hormones in this respect is not well known. Plasma concentrations of these hormones show variation during estrous cycle. The role of alpha2 receptors in tonic pain has been pointed out. The aim of the present study was to investigate the agonist and antagonist effec...
Flowering, the beginning of reproductive growth, is a significant stage in growth and development plants. Conifers are economically ecologically important, characterized by straight trunks good wood quality and, thus, conifer plantations widely distributed around world. In addition, species have tolerance to biotic abiotic stress, stronger survival ability. Seeds some species, such as Pinus kor...
