This work extends the idea of using a cyclotron-based antineutrino source for purposes of neutrino *** baseline experiments suffer from.d.generacies and correlations between Θ_(23), δ_(CP) and the mass ***, the combination of a superconducting cyclotron and a big liquid scintillator detector like JUNO in a m.d.um baseline experiment, which does not depend on the mass hierarchy, may allow to determine whether the position of the mixing angle Θ_(23) is in the lower octant or the upper octant. Such an experiment would improve the precision of the Θ_(23) measurement to a degree which depends on the CP-phase.

Rational construction of hierarchical multi-component materials with abundant heterostructure is evolving as a promising strategy to achieve excellent metal-organic frameworks(mOFs)based electromagnetic wave(EmW)***,hierarchical heterostructure WS_(2)/CoS_(2)@carbonized cotton fiber(CCF)was fabricated using the ZIF-67 mOFs nanosheets anchored cotton fiber(ZIF-67@CF)as a precursor through the tungsten etching,sulfurization,and carbonization *** from the synergetic effect of dielectric-magnetic dual-loss mechanism,the hierarchical heterostructure and multicomponent of WS_(2)/CoS_(2)@CCF also display improved impedance ***,numerous W-S-Co bands and heterojunction interfaces of heterogeneous WS_(2)/CoS_(2)are beneficial to promoting additional interfacial/dipole polarization loss and conductive loss,thereby enhancing the EmW attenuation *** on the percolation theory,a good balance between impedance matching and EmW absorption capacity was achieved for the WS_(2)/CoS_(2)@CCF/paraffin composite with 20 wt.%filler loading,exhibiting strong EmW absorption capability with a minimum reflection loss(RLmin)value of−51.26 dB at 17.36 GHz with 2 mm thickness and a maximum effective absorption bandwidth(EABmax)as wide as 6.72 *** research will provide new guidance for designing high-efficient mOFs derived EmW absorbers.

Appropriate information on solar resources is very important for a variety of technological areas, such as agriculture, meteorology, forestry engineering, and water resources, particularly for an innovative technology such as solar energy. In the market entry process of an innovative technology such as solar energy, the increased and sustained deployment of this energy technology strongly depends on the economy and reliability of the solar systems installed. The economy and reliability of a system are the consequences of a well-prepared project, resulting from an accurate knowledge of the solar resource available. Therefore, knowing the potential of the solar resource accurately is not only a need but also an imperative for the larger diffusion and use of the solar energy. The existing sources of the information on radiation in mG are quite varied, both at the institutional level and in different types of publications. The publications containing this information are project reports, internal reports of institutions, and several magazines. Thus, the quality of the data varies considerably, the information presents spatial and temporal discontinuity;moreover, the instruments and the measurement units are not standardised. The general objective of this paper is to recover, to qualify, to standardize, and to make available the best information from the current existing solar resource in mG, Brazil, either in the form of isoline charts of solar radiation or a numerical database. In this paper, the procedure to elaborate the maps of daily solar radiation and insolation, along with the monthly and annual averages, is described. We present one map with the localisation of the recording stations in addition to one annual and 12 monthly contour maps. The map of the daily global solar irradiation and the annual average determined in this project show that solar radiation on the state of minas Gerais ranges from 4.5 to 6.5 kWh/m2. The maximum values occur in the northern regio

本文考察了不同镍基高温合金与两种化学成分的mCrAlY粘结涂层的互扩散行为。为明确涂层沉积过程对其影响,本文采用超音速火焰喷涂(HVOF)和低压等离子喷涂(LPPS)两种不同的喷涂工艺制备了mCrAlY粘结涂层。本文重点考察Kirkendall孔隙度的演变过程,其主要形成于基材与粘结层界面,并主要受涂层及基材化学成分的影响。实验研究表明:涂层沉积过程对Kirkendall孔隙度的演变过程具有较大影响。孔隙的形成可导致基材与涂层间粘结强度的降低,甚至引起涂层系统的功能性破坏。本文在涂层沉积后,将样品置于1050℃条件下进行最长可达2000小时的退火。为评估Kirkendall孔隙度,对样品进行微观组织和化学成分分析。结果表明:Kirkendall孔隙度的形成量以及形成位置很大程度上受涂层沉积过程的影响。一般而言,通过HVOF工艺制备粘结涂层的样品提高了元素扩散速率。由于在涂层沉积之前进行了表面处理,故造成上述现象的主要原因为基材材料的再结晶。

82P 和86Rb 双标记植物样品的总放射性强度测量问题,借助切伦柯夫技术已获解决。随后,由于阴离子交换层析法的应用,使得从物理方法上将86Rb 组分从样品中分离出来并测定其放射性强度亦成为可能。将样品的总放射性强度减去86Rb 的放射性强度,便可得到32P 的放射性强度。这一方法优于那种基于β能谱形状和半衰期差异的放射性核素鉴别测量法。

Journal of Geoscience and Environment Protection 2017年第13期5卷 1-17页

The pharmaceutical compounds were analyzed in 14 sampling sites and pointed out the pollution sources related to raw sewage input and urban drainage discharge. Five m.d.cine compounds, one illicit drug, and its metabolite were the higher measured content using analytical improvements tailored to identify and quantify organic compounds in low water content. The use of SPE cartridges followed by liquid chromatography with tandem mass spectrometry (LC-ESI-mS/mS) points out the Guavirutuba tributary as the primary water pollution source with higher concentrations in 2011 for pharmaceuticals, cocaine, and benzoylecgonine (metabolite) in the range of 6.7 ± 0.9 ng L-1 to 27.386 ± 142 ng L-1. The Jaceguay stream also located in Guarapiranga was the most preserved area and provided analytical values correspondent which lowered contamination content. Such concentrations mean a possible and feasible water restoration target. The most common compounds (above 90% samples) were: caffeine, atenolol, carbamazepine, cocaine, and benzoylecgonine. The integrated risk index for aquatic chemical pollution (IRICAP) confirms the higher contamination near Guavirutuba stream and the lower near the Jaceguay stream. Published results of cocaine and benzoylecgonine content in Guarapiranga basin corroborated with the analytical results.
