Jun 07, 2019 In addition, we used the HL-1 and HBWH-1 B. dothidea strains isolated from sand pear trunks collected from Hubei Province (Wang et al. 2014 Wang et al. 2017b). Colonies of the four B. dothidea strains (LW-CP, LW-C, LW-P and Mock) were cultured for 3 days on potato dextrose agar (PDA) and Murashige Skoog (MS) at 25 C in darkness, respectively.
Sand filters are widely used for well water purification in endemic arsenicosis areas, but arsenic (As) removal is difficult at low intrinsic iron concentrations. This work developed an enhanced sand filter by electrochemically generated Fe(II) from an iron anode. The efficiency of As removal was tested in an arsenic burdened region in the Jianghan Plain, central China. By controlling a ...
Sep 22, 2015 In soils and sediments, manganese oxides and oxygen usually participate in the oxidation of ferrous ions. There is limited information concerning the interaction process and mechanisms of ferrous ions and manganese oxides. The influence of air (oxygen) on reaction process and kinetics has been seldom studied. Because redox reactions usually occur in open systems, the participation of air
Barnyardgrass Echinochloa crus-galli (L.) P. Beauv. is a noxious grass weed that infests rice fields and causes huge crop yield losses.In this study, we collected 12 E. crus-galli populations from rice elds of Ningxia Province in China and investigated the resistance levels to the acetolactate synthase (ALS) inhibitor penoxsulam and the acetyl-CoA carboxylase (ACCase) inhibitor cyhalofop ...
Jul 15, 2015 Bermudagrass is widely utilized in parks, lawns, and golf courses. However, cold is a key factor limiting resource use in bermudagrass. Therefore, it is meaningful to study the mechanism of bermudagrass response to cold. Nitric oxide (NO) is a crucial signal molecule with multiple biological functions. Thus, the objective of this study was to investigate whether NO play roles in bermudagrass ...

The SAND token is a standard version ERC-20 token, which means owners can stake it and benefit from staking rewards. Unlike the proof-of-work ( PoW ) consensus mechanism employed by the Bitcoin blockchain, PoS does not require vast amounts of electrical or computing power to validate transactions.
A novel hydrophilic polyurethane (abbreviated as W-OH) was developed and applied as a sustainable sand-fixing material. This paper on the chemical sand fixation mechanism of W-OH discusses the adhesive force between the W-OH solid and sand particles. The solidification mechanism was investigated and the solidifying time was tested. And then the thickness and porosity of the W-OH
