The Yb:Y3Al5O12/Y3Al5O12 (Yb:YAG/YAG) composite crystals were prepared by thermal bonding method with different technological parameters. The bonding in-terface of the composite crystals were observed by optical microscope, scanning electron microscope, and atom force microscope. The light scattering experiments for bonding interface of the composite crystals were measured by the laser and transmission spectra. All experiments show that high-quality Yb:YAG/YAG com-posite crystals without space transition layer and light scattering on the bonding interface can be obtained by thermal bonding method under appropriate technological parameters.

A survey was completed during the last five years (2014-2018) to update and assess changes in the cassava pests and diseases occurrence as well as to understand how these changes occur regarding the recent new viruses spread under a climate change context in the South-Kivu region, Democratic Republic of congo. The eight territories of South-Kivu were surveyed during the rainy seasons from 2015 until 2017 except for Uvira and Fizi where data were recorded in 2018 regarding the prevalence of unstable agro ecological factors which may influence pest and diseases dynamic in these two territories. During the data collection, pests and disease incidence and severity were recorded as well as the sampling of cassava leaves for molecular viruses’ detection. The recorded data showed that cassava mosaic disease (cMD) remains the most encountered disease (75% - 80%) and its vector (the whitefly Bemisia tabaci) the most important pest (10 - 18 adult whiteflies per leaf). The major changes were recorded for cassava brown streak disease, recently reported in the region, for which a significant increase was recorded, with not reports before 2012 to 70% - 80% incidence in 2018 in the Ruzizi plain area (Uvira and Fizi). Molecular detection revealed a coexistence of both two viruses, the cassava brown streak virus (cBSV) and Ugandan cassava brown streak virus (UcBSV) in single and mixed infections. co-infections cassava mosaic and cassava brown streak diseases were frequently recorded resulting in severe expression leaves’ symptoms and tuber yields’ losses. common pests and diseases considered as minor have drastically become serious threat to cassava production by increasing both their incidence and severity values. The cassava bacterial blight (20%), cassava green mite (20% - 70%), cassava mealy bugs and cassava grasshoppers were recorded as a great challenge in relation with an occurrence of long dry season resulting in four consecutive dry months without rain. The high occurrence

Purpose. To determine the feasibility of RNA collection in a multi-institutio nal cooperative group setting to be utilized for micro-array gene expression an alysis, and to describe the methodology. Methods. RTOG c0128, a phase I-II, pro tocol was designed to look at the safety and efficacy of external beam radiation therapy to 45 Gy with concomitant 5-FU and cisplatin chemotherapy, brachythera py to deliver 85 Gy to point A, and celecoxib at 400 mg twice daily for 1 year. Patients had the option of participating in a tissue collection portion of the p rotocol to be utilized for micro-array gene expression analysis before treatmen t and at the time of the first implant. RNA quality was determined by two parame ters: the absorbance ratio at 260 nm/280 nm, and by the ratio of the integrated peak of 28S RNA to 18S RNA after gel electrophoresis. Results. From August 2001 to March 2004, 84 patients were accrued to the trial, and tissue was obtained pr ior to initiation of therapy on 34 patients (40%). FIGO stages for the patients who provided tissue were IB (23%), II (57%), and IIIA-IVA (20%). Additional ly, biopsies were obtained at the time of the first implant from 22 of the accru ed patients making paired samples available on 26%for RNA extraction and micro -array gene expression analysis. The mean ±SEM amount of tissue obtained pretr eatment was 97±13 mg compared with 51±8 mg for tissue obtained at the time of the first implant (P = 0.009). The mean total RNA extracted from the samples pri or to treatment was 119 ±19 μg versus 35 ±6 μg at the time of the first proc edure (P = 0.001). The RNA quality was assessed via the absorbance ratio at 260 nm divided by 280 nm. The mean values pretreatment and at first implant were 1.8 7 ±0.07 versus 1.66 ±0.11, respectively (P = 0.002); however, the integrated p eak of 28S RNA to 18S RNA after gel electrophoresis was not significantly differ ent (P = 0.26). conclusions. RNA extraction for gene expression analysis can be success

An one-year of sampling aerosol program was carried out during the period of April 1995 to April 1996 at coastal region, cape D′Aguilar, in Hong Kong. The trace element composition of aerosol particles(TSP and PM 10 ) were measured and analyzed by using the Instrumental Neutron Activation Analysis(INAA) and Inductive couple Plasma-Mass Spectrometry(IcP-MS) techniques. The results showed that the polluted elements such as: V, Zn, As, Pb, cd, Sb, I, Se, Bi, with high enrichment factor(E.F) values, are derived from anthropogenic sources, while Sc, Al, Fe, Mn, Sm, La, Sr are less than 10 in E.F, these elements are related the crust and soil. The concentration of the trace elements are present seasonal variation i.e. summer low and winter high, whereas the V or noncrustal V(V *) present summer high and winter low, this phenomenon might be explained by local or regional oil combustion sources. Use three type of elemental ratio, e.g. La/Sm, Mn */V * and Bi/Al indicate that both TSP and PM 10 of La/Sm ratios are mainly related to soil and dust, Mn */V * are probably represent fossil combustion and Bi/Al are possibly associated with refuse incineration, ferromanganese alloys and aluminum production. The varimax rotation factor analysis for trace elements was performed. By means of the absolute principal component analysis(APcA) and multiple regression, the contribution of trace elements to possible sources and overall means of trace elements were estimated. The results showed that the present station is impacted by the anthropogenic species, although the quantities are different during the summertime and wintertime.

前言尽管锌的标准电势值相当低,但由于在金属表面可形成稳定的保护膜,所以它在接近中性水溶液或在一般大气条件下有很好的耐蚀性。然而,在较苛刻的腐蚀条件下,可导致保护膜的破坏,最常见的腐蚀产物是在潮湿贮存条件下出现白色锈斑。通常用含有铬酸盐类或亚硝酸盐类的无机配方就可以得到预防,而且有许多报道和专利可供选用。

Mixed ammonium-transition metal salts with formula of （NH4）xMyHzPMo12O40 （M = Ni^2＋, co^2＋ or Fe ^3＋） denoted as MPMo12 have been investigated for the oxidation of propane, with molecular oxygen, at temperature range between 380 ℃ and 420 ℃ after in-situ pre-treatment performed at two heating rate of 5 or 9℃/min. They were characterized by BET method, XRD, UV-Vis and IR techniques. The catalysts were found to be active in the propane oxidation and selective to propene or acrolein, in particular for samples pre-treated with the heating rate of 9℃/min. FePMo12 was found to be a more active catalyst for propene （17.2% yield） with minimal over deep oxidation （0.3% yield in cOx）.
