Variation of soil and plant characteristics among old world bluestem species

Agricultural Sciences 2011年第3期2卷 347-356页

作者： Ted m. Zobeck Vivien G. Allen Jenny Jo Cox dirk philipp department of Plant and Soil Science Texas Tech University Lubbock TX USA University of Arkansas Fayetteville AR USA USdA-ARS Cropping Systems Research Lab Lubbock TX USA

Old world bluestems (Bothriochloa spp.) have been successfully introduced as grasses for livestock forage in the semiarid Texas High Plains. Questions remain, however, on effects of these grasses on soil resources. We tested the hypothesis that differences in grass species produce differences in soil properties important to crop growth and useful in selecting the optimum species for the Southern High Plains of Texas. Three old world bluestem (Bothriochloa) species [C.E. Hubbard ‘Caucasian’, B. caucasica (Trin.);‘WW Spar’, B. ischaemum (L.) *** ischaemum (Hack.);and S.T. Blake ‘WW-B dahl’, B. bladhii (Retz)] were grown in a randomized complete block design, with three replications, for nine years on a clay loam soil near Lubbock, Texas. Soil samples were collected in the ninth year to determine soil texture, wet aggregate stability, bulk density (Bd), soil organic carbon (SOC), particulate organic carbon (POC), and soil strength as measured by the cone pentrometer. The grass species differed in their above-ground biomass and below- ground root production. In the ninth year of production, Bothriochloa caucasica and B. bladhii produced about twice the above-ground biomass with about 25% fewer roots than B. ischaemum. Soils where B. caucasica was grown had the highest Bd (1.36 mg m–3) and B. ischaemum had the lowest (1.31 mg m–3). The soil in which B. ischaemum was growing had a lower Bd, greatest root biomass, organic matter content, and aggregate stability suggesting superior soil quality for agricultural production. The species B. bladhii, however, often exhibited soil properties that were similar to both other species tested. Since Bothriochloa bladhii had superior or similar soil properties for plant growth among the species tested and has been shown to be higher in forage quality, animal performance, and carrying capacity than the other species, it appears to be the best choice among these three species to optimize both animal performance and desirable soil p

欧洲钢铁工业的环境保护已经达到了很高的水平.20世纪60年代初,保护环境一般认为只是局限于限制工业对人们的影响.现在,尤其是在罗马协议(Club of Rome)的努力之下,环保的范围从节约资源延伸到到整个自然环境的保护,而后产生了目前应用中的工业过程和产品生产周期.整体来说,保护环境的所有途径都被视为是未来平衡发展的先决条件.欧盟环境保护技术的情况可以以德国为例,更准确地说是杜伊斯堡的蒂森克虏伯钢厂(ThyssenkruppStahl AG),其粗钢产量约占德国总产量的35%.钢铁工业环境保护的重点仍然是维护空气质量,在此目的下,进行除尘处理.由烟囱处取样获得目前的除尘水平来看,今后的除尘主要是控制粉尘扩散和减少细小微粒的排放.钢铁工业环境保护的关键策略就是循环利用,它能起到与环境协调一致的作用,能够解决相关工艺中需要的大量的原料问题.德国的蒂森克虏伯钢厂(Thyssenkrupp Stahl AG)现在炉渣的综合回收率水平已接近95%,其中冶金渣的回收利用率尤为突出.在德国,高炉渣利用率达到了100%,同时炼钢渣的利用率也超过了90%,每吨粗钢的耗水量也控制在在100 m3的范围内.大量的努力不仅保证了有效的回收和再生利用工序,而且冷却水的利用也保证了新水的补充率降低到每吨粗钢15 m3左右.污染控制除跟主要环境即空气、水和土壤有关外,已扩展到回收过程再利用的水平,更多地重点渐渐地放到相关产品的环境保护.产品和原料却日益受到生产商和消费者的重点检验,有点与环境协调性标准相反.组织机构的环境保护手段包括环境管理系统的认可、生态平衡、政府部门的自愿协议以及提高公众的信息、教育水平.欧洲的钢铁工业,当然也包括德国,都已经意识到环境保护的重要性同工业研究与开发的重要性处于同等地位.一个典型的例子就是超薄板汽车用钢项目,这个与产品相关的研究引入了35家合作厂商共同研究一个比目前传统的汽车车身更结实、更轻的项目.欧洲钢铁厂家的联合合作已经成功研究出应用于烧结厂的减少二恶英(dioxin)排放物的吸收工艺.用褐煤焦尘作为吸附剂,已能够平均减少排放物大约70%.很可能2003年在杜伊斯堡的Thyssenkrupp Stahl AG将被授权建全世界最先进的焦化厂.在这个项目过程中研究出的主要部分成果,例如低尘低烟煤湿熄法和减少PAH排放物的单室压力控制系统,会恰当的应用于新的工厂.另一个主要进步是Thyssenkrupp Stahl AG研制的Hamborn OxiCup竖炉,它有湿法冶炼和排除含铁残渣的功能.此技术预计成为回收利用铁水和钢产品中产生的粉尘和泥浆这一难题的解决方案.德国的局势尤其显示出环境法规的落实正开始对经济发展和劳动力市场起到不利影响.盛行的经济技术条件需要合法的体制治理环境保护的合理化.将来任何进一步的措施都要考虑这一事实,既要获得可持续发展,又要考虑到经济发展和社会需求.

detecting Strength and Location of Jump discontinuities in Numerical data

引用

Applied mathematics 2013年第12期4卷 1-14页

作者： philipp Offner thomas Sonar martina Wirz Computational mathematics AG Partielle DifferentialgleichungenTU BraunschweigBraunschweigGermany

In [1] and some following publications, Tadmor and Gelb took up a well known property of conjugate Fourier series in 1-d, namely the property to detect jump discontinuities in given spectral data. In fact, this property of conjugate series is known for quite a long time. The research in papers around the year 1910 shows that there were also other means of detecting jumps observed and analysed. We review the classical results as well as the results of Gelb and Tadmor and demonstrate their discrete case using different estimates in all detail. It is worth noting that the techniques presented are not global but local techniques. Edges are a local phenomenon and can only be found appropriately by local means. Furthermore, applying a different approach in the proof of the main estimate leads to weaker preconditions in the discrete case. Finally an outlook to a two-dimensional approach based on the work of móricz, in which jumps in the mixed second derivative of a 2-d function are detected, is made.

BACkGROUNd Individuals with heart failure(HF) frequently experience limitations in mobility, but specific aspects of these limitations are not well understood. This study investigated the association of HF severity, based on the New York Heart Association(NYHA) classes, with digital mobility outcomes(dmOs) and handgrip strength in older inpatients with *** For this explorative analysis, hospital admission and discharge data from an ongoing, prospective cohort study were used. The sample included older participants with HF and a sub-sample of heart-healthy individuals. Participants were equipped with a wearable inertial measurement unit(ImU) system during mobility performance(balancing, sit-to-stand transfer,walking). We analyzed the association between 17 dmOs and HF severity with multiple linear regression *** The total sample included 61 older participants(65–97 years of age, 55.7% female). Of all dmOs, only sway path in a semi-tandem stance position(m/s^(2)) showed a relevant association with NYHA classes(admission: β =-0.28, P = 0.09;discharge:β =-0.39, P = 0.02). Handgrip strength showed a trend towards a significant association(admission: β =-0.15, P = 0.10;discharge:β =-0.15, P = 0.19).CONCLUSIONS This is to our best knowledge the first analysis on the association of HF severity and ImU-based dmOs. Sway path and handgrip strength may be the most promising parameters for monitoring mobility aspects in treatment of HF.

Patients who suffer from a high spinal cord injury have severe motor disabilities in the lower as well as in the upper extremities. Thus they rely on the help of other people in everyday life. Restoring the function of the upper limbs, especially the grasp function can help them to gain some independence. Using EEG-based neuroprosthetics is a way to help tetraplegic people restore different grasp types as well as moving the arm and the elbow. In this work an overview of non-invasive EEG-based methods for restoring the hand and arm function with the use of neuroprosthetics in individuals with high spinal cord injury is given. Since the Graz BCI group is leading in this area of non-invasive research mainly, the work of this group is represented.

BACkGROUNd Transjugular intrahepatic portosystemic shunt(TIPS) placement is an effective intervention for recurrent tense ascites. Some studies show an increased risk of acute on chronic liver failure(ACLF) associated with TIPS placement. It is not clear whether ACLF in this context is a consequence of TIPS or of the pre-existing liver *** To better understand the risks of TIPS in this challenging setting and to compare them with those of conservative *** Two hundred and fourteen patients undergoing their first TIPS placement for recurrent tense ascites at our tertiary-care center between 2007 and 2017 were identified(TIPS group). Three hundred and ninety-eight patients of the same time interval with liver cirrhosis and recurrent tense ascites not undergoing TIPS placement(No TIPS group) were analyzed as a control group. TIPS indication,diagnosis of recurrent ascites, further diagnoses and clinical findings were obtained from a database search and patient records. The in-hospital mortality and ACLF incidence of both groups were compared using 1:1 propensity score matching and multivariate logistic *** After propensity score matching, the TIPS and No TIPS groups were comparable in terms of laboratory values and ACLF incidence at hospital admission. There was no detectable difference in mortality(TIPS: 11/214, No TIPS 13/214). during the hospital stay, ACLF occurred more frequently in the TIPS group than in the No TIPS group(TIPS: 70/214, No TIPS: 57/214, P = 0.04). This effect was confined to patients with severely impaired liver function at hospital admission as indicated by a significant interaction term of Child score and TIPS placement in multivariate logistic regression. The TIPS group had a lower ACLF incidence at Child scores d a higher ACLF incidence at ≥ 11 points. No significant difference was found between groups in patients with Child scores of 8 to 10 *** TIPS placement for recurrent tense as
