作者： Taylor mullins PA 钱苏鸣

反射性交感神经营养不良(RSD)包括一组以剧痛为特征的临床病例,如灼性神经痛、外伤后骨质疏松及肩-手综合征。临床上许多疗法对 RSD 都难以奏效。RSD 伴发的水肿和关节僵硬难以缓解,且常常随着治疗而恶化。RSD 以与最初损伤不相符的剧... 详细信息

反射性交感神经营养不良(RSD)包括一组以剧痛为特征的临床病例,如灼性神经痛、外伤后骨质疏松及肩-手综合征。临床上许多疗法对 RSD 都难以奏效。RSD 伴发的水肿和关节僵硬难以缓解,且常常随着治疗而恶化。RSD 以与最初损伤不相符的剧痛为特征。这种疼痛常被描述为烧灼痛,说明 c-纤维受到了刺激。疼痛同时伴发有严重水肿、关节僵硬和肢端变色。诊断 RSD 必须具备以下3点:①疼痛性损害;②身体素质;③交感神经反射异常。疼痛性损害是该病的起始症状,它既可以是由于损伤(如前臂骨折)。

A systematic approach was developed to investigate the stability of gentamicin sulfate(GS) and GS/poly(lacticco-glycolic acid)(PLGA) coatings on hydroxyapatite *** influence of environmental factors(light,humidity,oxidation and heat) upon degradation of the drug in the coatings was investigated using liquid chromatography with evaporative light scattering detection and mass *** coated rods were found to be stable across the range of environments assessed,with only an oxidizing atmosphere resulting in significant changes to the gentamicin *** contrast,rods coated with GS/PLGA were more sensitive to storage conditions with compositional changes being detected after storage at 60 °c,75% relative humidity or exposure to *** effect of γ-irradiation on the coated rods was also investigated and found to have no significant ***,liquid chromatography–mass spectrometry analysis revealed that known gentamines c_1,c_1 aand c_2were the major degradants *** degradation of gentamicin coatings did not produce any unexpected degradants or impurities.

The present internet version which was established and consolidated over internet protocol version 4 (IPV4) in 1981, and whose amount of public addresses available is insufficient to meet the demands explosion and current internet multimedia devices, services and application intensive environment has posed serious problems of incomplete web transactions. Stakeholders and communication industry in Nigeria are unwilling and feel reluctant to migrate to IPV6 because of inhibiting factors. This needs urgent redress to overcome the tractions that are responsible for apathy to migration from IPV4 to IPV6 launched in 1994 by the Internet Engineering Task Force (IETF). If nothing is done, sometime, internet may run out of space, ARIN [1]. Users may suffer disillusionment and frustration. The objective of this study therefore is to design a model for predicting migration from IPV4 to IPV6 in Nigeria by 2027 based on growth trend developed from statistical indices. The essence is to explore and analyze the factors that can encourage migration to IPV6 in the next 10 years and use those factors to forecast growth, so that IPV6 will receive boost in terms of growth and patronage. The study also aims at designing a predictive model that simulates the behaviour of the restrictive policies on migration to 1PV6 so as to ascertain the current impact on non-motivation and unwillingness to migrate to IPV6 in Nigeria. The motivation behind this study is to identify the inhibiting factors responsible for lack of motivation to migrate from IPV4 to IPV6 in Nigeria. The methodologies that were deployed in packaging the model include the statistical methodology, Structured Systems Analysis and Design Methodology (SSADM) and prototyping. The result is indeed functional software, programmed through Visual Basic. Net. (***) that can be used to simulate the behavioural impact of any government policy formulation for Telecommunication industry and stakeholders.

近年来,由于小型果树的发展,苹果园的规划管理已发生明显的变化。长势慢于普通型树的短枝型苹果已在美国得到普及。小型果树的开发利用导致了较高密度的栽植,一般可取得结果早,单产高,但果园寿命一般要缩短的趋势。本文是在美国田纳西州克劳斯维尔附近的高原试验站所作的不同砧穗组合和不同栽距对产量、成活率和干粗的试验。

The group Ⅲ nitrides are an important class of materials with aplications in UV and visible optoelectronics,high temperature electronics,cold cathodes and solar blind *** recent years,with the realisation of nitride based LEDs,the use of GaN IED has the potential to compete with 1raditional filament and discharge lamps,for the provision of white lighting,and there has been an explosion of interest in the MOcVD growth of GaN based materials with an increasing focus on large area multiwafer reactors and wafer *** paper will review the design philosophy and characteristics of close-coupled showerhead reactors,relating these to the requirements of group Ⅲ-nitride growth,and will present a selection of data resulting from the operation of such *** results suggest that the close coupled showerhead style of reactor is very suitable for the growth of GaN based structures in both research and production environments.

complexes of the general formula [MBr2(TMTU)n] (where M is Mn, Fe, co, Ni, cu, Zn or cd;TMTU is Tetramethylthiourea;n is 0.75, 2 or 3) were obtained by the reaction of salts and ligand in solution. The bromides were selected among several other salts because they had thermochemical data in the literature. Properties as capillary melting points;c, H, N, Br and metal contents;TG/DTG and DSc curves;and IR and electronic spectra were determined. The values of several thermodynamic parameters for the complexes were found by solution calorimetry. From them, the standard enthalpies of the metal-sulphur coordinated bonds were calculated. The standard enthalpies of the formation of the gaseous phase adducts also were estimated.
