(Coleoptera: Curculionidae), with two essential oils for the degree of repellent activity, was evaluated in an experimental model in laboratory tests. The diatomaceous earth was obtained from three Romanian sources (Patirlagele, Urloaia and Adamclisi) and was applied at four doses of 100, 300, 500 and 900 ppm (5, 15, 25 and 45 mg, respectively) on three replicates each variant. Mortality of S. granarius adults was estimated after 7, 14 and 21 d of exposure on treated grain. The insecticidal efficacy of the examined diatomaceous earth against the granary weevil was highly influenced by exposure time, dose and essential oil type. The longer exposure times increased weevil mortality in the case of low doses (100 ppm and 300 ppm). After 60 d from the experiment initiation, the exposed grains from each variant were assessed about the progeny production. For the model proposed as bio-experiment, two essential oils in concentration of 80μL/L air and 125μL/L of Thymus vulgaris L. and Satureja hortensis L., respectively, were tested compared with untreated control in laboratory conditions. Both plant species belong to the family Lamiaceae, and the major active insecticidal compound was thymol among other providing to terpenoid class, such as eugenol and linalool. The species S. granarius chosen for experimental model was grown in the Research-Development Institute of Plant Protection (RDIPP) Bucharest bio-base. The results show that mortality induced from diatomaceous earth was at the level between 83.33% and 100% in all variants after 21 d, compared with untreated control and a standard product Silicosec.展开更多

In 2013, China Geological Survey Bureau deployed a project named "Experimental Investigation of Integrated Prospecting Technology for Concealed Carbonate-Type Lead-Zinc Deposits in the Region of Sichuan, Yunnan and Guizhou Provinces". This project has been implemented by the Chengdu Center of China Geological Survey since 2013, and the project has run for 3 years. The general objective of this project is to establish an effective and adaptable integrated prospecting methodology (including geological, geophysical and geochemical techniques) in search for deep concealed lead-zinc deposits.展开更多

After meticulously preprocessing of the GRACE KBRR data, the root mean square of its post residuals is about 0.2 micrometers per second, and seventy-two monthly temporal solutions truncated to degree and order 60 are computed for the period from January 2003 to December 2008. After applying the combi- nation filter in WHU-Grace01s, the global temporal signals show obvious periodical change rules in the large-scale fiver basins. In terms of the degree variance, our solution is smaller at high degrees, and shows a good consistency at the rest of degrees with the Release 05 models from Center for Space Research (CSR), GeoForschungsZentrum Potsdam (GFZ) and Jet Pro- pulsion Laboratory 0PL). Compared with other published models in terms of equivalent water height distribution, our solution is consistent with those published by CSR, GFZ, JPL, Delft institute of Earth Observation and Space system (DEOS), Tongji University (Tongji), Institute of Theoretical Geodesy (ITG), Astronomical Institute in University of Bern (AIUB) and Groupe de Recherche de Geodesie Spatiale (GRGS}, which indicates that the accuracy of WHU-Grace01s has a good consistency with the previously published GRACE solutions.展开更多

It should be noted that although the study of the pathophysiology of AKI, as well as supportive therapies such as blood purification therapy, has obtained significant progress, the incidence of end- stage renal diseases and mortality rate caused by AKI are still high. Therefore, it has a great practical significance to make efforts to study prevention and treatment of AKI.展开更多

Most of the scholars hold that the attention paid to the early diagnosis and intervention of ARF was insufficient in recent years. Lots of clinical researchers indicated that even a slight impairment of renal function could result in the increasing of the morbidity and mortality of ARF.展开更多

The topic of my talk was 'How to write and submit scientific papers for publication: guidance for Chinese scholars in the field of integrative medicine'. My primary purpose for accepting the invitation to speak at the conference was educational, that of delivering scientific writing guidelines, but my personal reasons included my interest in learning about the Chinese version of integrating Traditional Chinese Medicine and Western Medicine. In addition, I was making first trip to China's Mainland. In this brief report, I would like to share my sketch of the conference and my impressions.展开更多
