THE oceanic lithosphere is composed of oceanic crust and upper mantle. It is widely accepted that the Troodos ophiolitic section represents the oceanic crust section, which consists of ultramafic cumulates in the bottom, and grades upward into cumulative gabbros, isotropic gabbro, sheeted dikes and pillow lavas, covered by abyssal sediments. According to the marine geophysical investigation, the oceanic crust can be divided into three layers which from top to bot-

PI novel caged bicyclic phosphate flame retardant tri(1-oxo-2,6,7-trioxa-1-phosphabicyclo [2.2.2] octane-methyl) phosphate (Trimer) was synthesized from 1-oxo-4-hydroxymethyl-2,6,7-trioxa-1-phosphabicyclo [2.2.2] octane (PEPA) and phosphorus oxychloride in this paper. Its structure was characterized by elemental analysis. FTIR, H-1 NMR. P-31 NMR and X-ray diffraction analysis.

A model for the chain-to-plane charge transfer is proposed to account for the two plateaus,at 60 K and at 90 K,of the Tc(x) characteristics of the YBa2Cu3O6+x high-Tc *** is assumed that the number of holes transferred from a CuO chain of length l to two nearby CuO2 sheets is proportional to l(that is,to the number of oxygen atoms in the chain),if the chain length is greater than,or equal to,a certain critical chain length,lcr,that is required to trigger the charge transfer *** holes are assumed to have been transferred from chains of length l更多还原AbstractFilter('ChDivSummary', 'ChDivSummaryMore', 'ChDivSummaryReset');

Amorphous Ni-Mo-Fe-Zn quaternary alloy coatings are developed by means of electrodeposit, and after most of zinc is leached out their electrocatalytic activity toward the hydrogen evolution reaction (HER) in alkaline media is studied using electrochemical polarization and a.c. impedance techniques. The results show these coatings have very high electrocatalytic activity and excellent stability. This might benefit from the increased active surface area, well-pronounced synergism as well as their amorphous structures. The HER proceeds through the Volmer-Heyrovsky mechanism with a rate-determination-step (RDS) of Volmer at high overpotentials and the HER is controlled by Heyrovsky in lower overpotential areas.

Long-lasting insecticide-treated nets (LLINs) and indoor residual spraying (IRS) are the main indoor malaria vector tools control tools. The study examined housing characteristics and investigated the relationship between the total volume of household possessions, the volume of the sleeping room, and the hanging of LLINs. A total of 831 bedrooms were randomly selected in Benin in 2015. The findings showed that mud walls were predominant in rural areas (more than 75%), while metal roofs were common (77.3% - 97.9%). Battery-powered lighting was prevalent in rural areas in Northern (97%), while open-flame oil lamps were commonly used in rural areas in Southern (86%). The availability of correct bedding was low, ranging from 1% to 10% in all households. 20% of the bedrooms had at least 50% of their volume occupied by household possessions in urban areas. In rural areas, bedrooms without LLINs had a lower mean rate ratio of the volume occupied by possessions per the total volume of the room compared to bedrooms with at least one LLIN installed (p < 0.0001). The characteristics of human habitats are not favourable to the correct use of vector control intervention indoors. It is therefore important to improve people’s living conditions as the next step for malaria elimination.

The isoelectric point (IEP) and zero point of charge (ZPC) of magnesium aluminum hydroxide were studied by electrophoresis method, potentiometric titration method, and elemental analysis. Results showed that the charge of magnesium aluminum hydroxide was composed of variable charge and permanent positive charge. Because of the permanent positive charge, the IEP and ZPC obtained were higher than calculated. The LEP decreased and ZPC increased as X increased.

MOST of the preexisting paleomagnetic studies on the Tarim Basin were conducted within its northern ànd northwestern margins with the exception that few people have paid their attention to starting paleomagnetism study along the southern and southwestern rims of the basin. Here we report our new results from volcanic rocks distributed in Pulu area

上周和朋友聊起白酒美学盛典、白酒美学时代与文化时代的区别,我开玩笑说,一直以来,行业只讲白酒文化,就好比鸡蛋只煎了一面,需要适时换一面了,不然即使煎糊也难煎熟。
