为研究无机水化学离子在降雨径流示踪中的可能性,在实验流域实测降雨、地面径流、壤中流、地下水径流过程和流域内17个测孔的地下水过程中,施测了Na+,K+,Ca2+,Mg2+,Cl-,SO42-,HCO3-+CO32-,NO3-,F-,NH4-,PO42-,SiO2和pH,EC,18O的同步过程,还施测了少数土壤水水样。结果是:①在Ca2+与Cl-/SO42-和EC与Na+/(Na++Ca2+)的关系中以及除NO3-,NH4-,PO42-外的所有离子,都可识别出上述各种径流组分;②径流离子过程均与降雨离子过程相仿,随径流组分从地面到地下而渐趋坦化;③除个例外,离子浓度过程均以降雨为最小并从地面径流到地下水径流渐次增大;④降雨和地下水离子过程表现为径流离子过程的两端元;⑤在降雨和各径流组分中,18O过程与大部分离子过程有一定的同步性。从以上结果认为,降雨并不是流域径流离子输出的主要来源,然而却是形成它的主要控制因素。此外,有关试验结果还对应用Cl-进行地下水补给的估算方法提出了问题。

The advantages of combining qualitative and quantitative analysis on a single analytical technique have further extended the applications of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) to the quantitation of various biomolecules. To achieve absolute quantitation, it is necessary to perform a calibration with standard dilutions. For the purpose of measuring DNA samples, a pure DNA oligonucleotide at different concentrations was chosen as a standard to perform the calibration of MALDI-TOF MS. In order to overcome the variation of signal intensity from repeated measurements of each DNA standard dilution, fixed amount of an internal standard was added into each DNA standard dilution. Instead of maintaining at a constant level, the signals of fixed amount of internal standard were decreased 73% from its initial level while the signals of DNA standard continued to increase within a linear dynamic range for quantitation from 0.20 μM to 12.5 μM of DNA. Attempts to identify the cause of signal reduction were systematically carried out. This is the first report on the extent of signal reduction in quantitative MALDI-TOF MS. These results represent a limitation on using MALDI-TOF MS to monitor the changes in concentration of two different compounds within a chemical or biological system.

This study investigated the bending,compression as well as the bonding performance of CLT panels made from fast-growing timber species,i.e.,Laran(Neolamarckia cadamba)and batai(Paraserianthes falcataria).The variables studied were timber species(Laran and batai),layers of lamination(3-layer and 5-layer),loading direction in bending(in-plane and out-of-plane),loading direction in compression(x-,y-,and z-axis)and different treatment conditions for bonding performance *** desired outputs of this study were bending and compression properties(strength and stiffness)as well as bonding performance(block shear strength,wood failure percentage and delamination value).The bending and compression test were conducted according to EN16351:2015 and EN408:2012,*** the other hand,the bonding performance test was determined by block shear and delamination test based on EN16351:2015 and EN14374:2004,*** to block shear test,the samples were subjected to three different treatment *** results showed that CLT made from 3-layer Laran timber,loaded at out-of-plane direction exhibited the highest bending ***,CLT made from 5-layered batai timber,loaded at in-plane direction showed the lowest bending *** samples for compression loaded at x-axis exhibited the best compressive ***,Laran CLT showed greater bonding performance determined by shear test compared to batai CLT for both 3-and 5-layer *** the contrary,delamination results showed that batai CLT demonstrated better bonding performance compared to Laran *** terms of bonding performance measured by wood failure percentage(WFP),most samples under various treatment conditions showed WFP≥80%except for samples under wet condition with WFP≤60%.

For scientists pursuing drug development for prostate cancer,it is critical that an appropriate ex vivo or in vitro model system is available for *** research has generally consisted of:(1)finding the means to arrest fast growing cancer cells;or(2)(as a compromise)to slow down the excessive rate of cell growth;or in the best case(3)to kill the cancer cells whilst sparing the surrounding normal *** the knowledge of the biological nature of the cancer cell improves,it has become increasingly apparent that such a simplistic attitude to cancer therapy development or indeed diagnosis is rapidly outdated,and a closer liaison between the clinic and the laboratory studies is more important than ever as the author seeks to target specific gene expression pathways,specific signaling pathways,cancer specific mutations and indeed the interactions between cancer cells and their micro-environment,all of which provide a tremendous potential for novel therapeutic development.

American Journal of Climate Change 2015年第1期4卷 9-21页

The development of adaptation measures to climate change relies on data from climate models or impact models. In order to analyze these large data sets or an ensemble of these data sets, the use of statistical methods is required. In this paper, the methodological approach to collecting, structuring and publishing the methods, which have been used or developed by former or present adaptation initiatives, is described. The intention is to communicate achieved knowledge and thus support future users. A key component is the participation of users in the development process. Main elements of the approach are standardized, template-based descriptions of the methods including the specific applications, references, and method assessment. All contributions have been quality checked, sorted, and placed in a larger context. The result is a report on statistical methods which is freely available as printed or online version. Examples of how to use the methods are presented in this paper and are also included in the brochure.
