山羊的新用途

草食家畜 1989年第1期 5-5页

作者： Judith e.strom ,吕月华

在美国西部的各种毒草中,头号毒草是生长迅速的多年生阔叶大戟。它根系水平伸展,种子极易传播,因而蔓延很快,很难控制。大戟排挤了其它草类、作物和天然植物,被它侵染的牧场载畜量可下降50—75％。蒙大拿州斯蒂尔沃特县的官员偶然发现... 详细信息

在美国西部的各种毒草中,头号毒草是生长迅速的多年生阔叶大戟。它根系水平伸展,种子极易传播,因而蔓延很快,很难控制。大戟排挤了其它草类、作物和天然植物,被它侵染的牧场载畜量可下降50—75％。蒙大拿州斯蒂尔沃特县的官员偶然发现山羊喜食大戟甚于其它牧草。利用山羊可控制大戟蔓延。具体方法是:在大戟生长季节,将一群山羊(40只)在每块地方放牧2—5天,然后用卡车或拖拉机运到另一地方。整个生长季节,每块地方轮放两次,这样即使根除不了大戟,也能阻止其蔓延。

中国有色金属学会会刊：英文版 2007年第6期17卷 1282-1286页

Cr-alloyed MoSi2 was compared with monolithic MoSi2 with respect to oxidation at 450 ℃ for 456 h. Phases formed on Cr-alloyed MoSi2 after exposure are Cr2(MoO4)3, MoO3, and cristobalite (SiO2) according to X-ray diffraction results. Monolithic MoSi2 forms MoO3 and mainly amorphous SiO2. X-ray photoelectron spectroscopy indicates that the main oxidation product on the outermost surface is SiO2 for all studied samples. The samples form a relatively loose oxide but the oxide adherence improves with increasing Cr content. It is indicated that Cr addition can benefit pesting control in MoSi2.

SF6气体具有良好的絕緣性能和灭弧性能。这种性能主要是由于SF6分子能快速的吸收間隙中游离气体中的自由电子。用質子——光譜带有力的表明了SF6有形成負离子SF6和SF6的显明趋向。这两种离子質量很大,导电性不好,因而,SF6的击穿电压超... 详细信息

SF6气体具有良好的絕緣性能和灭弧性能。这种性能主要是由于SF6分子能快速的吸收間隙中游离气体中的自由电子。用質子——光譜带有力的表明了SF6有形成負离子SF6和SF6的显明趋向。这两种离子質量很大,导电性不好,因而,SF6的击穿电压超过空气的击穿电压2,4倍。但是,对于可靠地熄灭交流电弧来說,气体的击穿电压还是次要的。当电流通过零值时,灭弧介質首先应該有高的耐压强度恢复速率。間隙强皮的恢复速率或者間隙导电性的减少可以闡述为电弧的时間常数。从物理观点来看,这个时間常数可以認为是在給

New York USA

Background: Using baseline data from the Ziprasidone Observational Study of Cardiac Outcomes (ZODIAC), we assessed disease characteristics and prevalence of select comorbidities among subjects with schizophrenia in different clinical settings across 18 countries. ZODIAC was a randomized, open-label, one-year, large simple trial (LST) that enrolled 18,239 individuals with schizophrenia. Methods: Subjects were randomized to open-label treatment with ziprasidone (n = 9120) or olanzapine (n = 9119) in naturalistic (usual care) settings and followed for one year. Study sites (n = 749) applied minimal selection criteria in an attempt to make the study population as representative as possible of those receiving treatment in “real world” circumstances across the countries. Results: Mean patient age was 41 years, 55% were male, 34% were markedly ill or presented with more severe disease, and 66% of subjects had one or more select comorbid conditions [i.e. heart attack, stroke, hypertension, CAD/angina, high cholesterol/triglycerides, diabetes, or overweight (BMI ≥ 25)] at baseline. History of suicide attempt was greatest in the US (38%), compared with Sweden (34%), Brazil/South America (26%), Asia (23%), and eastern europe (20%). Overweight or obesity was the most prevalent comorbid risk factor, representing 60% of enrolled subjects, 70% of US subjects compared with 30% in Asia and 52% - 64% in the other regions studied. High cholesterol/triglycerides levels were found in 23% of US subjects compared with a relatively low prevalence in other countries (3% - 11%). History of cardiovascular or diabetes-related comorbidities was found in 31% of subjects. Current smoking (46.5%) and past smoking (11.8%) were common with men dominating the proportion of current smokers: US (61%);Asia (60%);Sweden (50%);eastern europe (49%);and Latin America (44%). Conclusions: Our findings indicate substantial baseline variations across countries in demographics, comorbid conditions, and psychiatr

目的声辐射力脉冲(ARFI)成像技术是通过测量组织剪切波速度来定量评价组织弹性的一项超声技术,目前该技术已被广泛应用于各种器官。本实验采用超声测定移植肾皮质剪切波速度,研究施加压力参数变化对组织剪切波速度变异的影响以及评估ARFI成像技术检测移植肾肾纤维化的诊断价值。方法本实验中测定31例移植肾肾皮质的剪切波速度,以穿刺活检结果为金标准。机器测定并施加探头压力的等效质量分别为:22、275、490、975、2040及2990g。结果 ANOVA统计学分析表明,剪切波速度与探头施压参数有关,差异具有统计学意义[F(2.85,85.91)=84.75,P<0.0005;施加的质量分别为22、275、490、975和2040g]。31例移植肾中有29例活检结果,移植肾纤维化程度为:12例0级,11例1级,5例2级,1例3级。单因素方差分析表明,针对不同纤维化程度,移植肾皮质剪切波速度差异不具有统计学意义。结论剪切波速度的测量值与施压大小有关,而与移植肾纤维化程度无关。要点①超声检查中的ARFI成像技术能定量评估组织弹性。②ARFI评估移植肾弹性与探头施压大小有关。③ARFI技术无法定量评估移植肾纤维化程度。④ARFI弹性评估会因施压的改变而改变。
