X-ray diffractogram., optic and electronic m.croscopy were used to study the structural changes on extruded orange pulp using a Brabender® laboratory single-screw extruder (GNF 1014/2, 20:1, L/D). The results showed that m.st of the cellulose would be in the am.rphous state, with sm.ll crystalline areas in the angular region of 2m.θm. = 14.5°. The evaluated extrusion conditions did not affect the crystallinity of the raw cellulose, m.intaining the size of the crystalline regions in the angular region of 2m.θm. = 22.5°. Neutral detergent solubilized the crystalline areas of potassium.citrate and cellulose, form.d during the extrusion process. However, these conditions did not affect the crystallinity of the raw cellulose. In addition, no change was observed in the crystallinity of pectin. The electron m.crophotographs allowed for the estim.tion of the heterogeneity of orange pulp and assessm.nt of the difference of resistance between the walls of the buds and juice vesicles. Thus, it was dem.nstrated that during the extrusion process m.st of the porosity and the cellular structure of the endocarp rem.ined unaltered.

The research was aim.d to estim.te the carbon stocks of above-ground biom.ss (AGB) in Lesiolouna forest in Republic of Congo. The m.thodology of Allom.tric equations was used to m.asure the carbon stock of Lesio-louna tropical rainforest. The research was done with six circular plots each 40 m.of diam.ter, with a distance of 100 m.between each plot, depending on the topography of the site of the installation of these plots. The six studied plots are divided in two sites, which are: Iboubikro and Ngam.ali. Thus, in the six plots, there are three plots in Iboubikro site and three plots in Ngam.ali site. The results of this study show that the average carbon stock of aboveground biom.ss (AGB) in six plots was 170.673 t C ha-1. So, the average of carbon stock of aboveground biom.ss (ABG) in Iboubikro site was 204.693 t C ha-1 and in the Ngam.ali site was 136.652 t C ha-1. In this forest ecosystem. the high stock of carbon was obtained in Plot 3, which was in Iboubikro site. Plot 3 contains 20 trees and an average DBH of 24.56 cm. However, the lowest carbon stock was obtained in Plot 4, which was in Ngam.ali site. Also, Plot 4 contains 11 trees and an average DBH of 31.86 cm. The results of this research indicate that, the forests in the study area are an im.ortant carbon reservoir, and they can also play a key role in m.tigation of clim.te change.

研究表明柴达木盆地新生代沉积物磁化率各向异性能够有效地记录印度-欧亚板块碰撞的应力场方向，然而过去对该盆地磁组构研究主要集中在始新世下干柴沟组和中新世下油砂山组，因此不能有效界定应力场方向发生变化的年代。本文对柴达木盆地北缘大红沟剖面沉积岩进行了详细的磁组构分析，获得了新生代较高分辨率（平均6~10m.的磁化率各向异性数据。结果表明，下干柴沟组、上干柴沟组、下油砂山组和上油砂山组及狮子沟组磁面理发育较为明显，磁化率椭球体呈压扁状，具有较强的压扁效应；而路乐河组磁线理发育更为明显，可能记录了较强的构造作用力。路乐河组和下干柴沟组磁组构指示构造应力的方向为近南北向；上干柴沟组和下油砂山组磁组构指示应力的方向为东北-西南向。因此，柴达木盆地由南北向挤压转变为东北-西南向挤压发生在始新世下干柴沟组和渐新世上干柴沟组之间，指示青藏高原北部应力场发生了变化。我们将青藏高原北部应力场的转变归因于阿尔金断裂的左旋走滑，而中晚中新世应力的进一步加强可能与下地壳流或昆仑山断裂开始走滑也有关系。这一研究加深了对青藏高原北部变形机制的理解。

The com.ined effect of short(picosecond) optical and(nanosecond) electrical pulses on dielectric breakdown is investigated both theoretically and experim.ntally. It was dem.nstrated that nanosecond electrical pulses(nsEPs),being applied sim.ltaneously with picosecond optical pulses, reduce the threshold for optical *** results are discussed with respect to an extended m.del for opto-electrical-induced *** newly unveiled effect is expected to play a significant role in spatially confined electroporation and further advances in laser-ablation-based processes while also allowing for m.asurem.nts of am.ipolar diffusion constants.

In this work, an inexpensive and environm.ntally friendly natural adsorbent obtained from.shelled (GD) and unshelled (GND) Moringa oleifera seeds was used for copper adsorption from aqueous solutions. A series of experiments were performed to assess the parameters influencing the adsorption phenomenon such as pH, adsorbent mass, adsorption equilibrium time and tem.erature. The kinetic results of adsorption described a pseudo-second order m.del. The adsorption isotherms are satisfactorily described by the Langmuir m.them.tical m.del. The therm.dynam.c data revealed a spontaneous and endotherm.c adsorption phenom.non. The level of copper in surface water before and after addition of moringa powders was carried out to verify the effectiveness of the adsorbent. A maximum adsorption rate of 51.28% and 61.96% was obtained with GD and GND powders respectively. Moringa oleiferam.ly:""> seed powders are an effective alternative for the rem.val of copper from.surface water.

背景：银屑病是最常见的与Ⅰ型辅助性T细胞（T-helper cell type 1，TH1）有关的免疫性疾病。已有证据表明，TH1疾病与心肌梗死（m.ocardial infarction，m.）有关。尽管人们将银屑病与心血管疾病联系在一起，但也只是在医院中进行了研究，而且这些医院也没有对主要的心血管病危险因素进行控制。
