2012年中国豆粕市场回顾及2013年趋势展望

2012年,国际大豆市场及国内豆粕现货市场行情可谓波澜壮阔,在天气行情市场之下,美国农业部(USDA)数次大幅调整预估美豆产量对国内外豆类市场影响重大.豆类市场从2012年初开始活跃,国内外期现货资金迅速堆积,期价、持仓和成交量均超越历史走势而渐近高位.随着市场对美国干旱影响的过度预期,豆类涨幅过多透支了天气利多的升水,在第四季度USDA又逐步上调大豆单产的利空打压下,资金开始撤离,价格见顶迅速回落.     

9月:大豆市场将继续保持弱势格局

2012年大豆市场回顾及2013年市场展望——全球大豆需求持续强劲 豆类或将演绎慢牛行情

12012年行情回顾2012年连豆期价重心较2011年上移,从年初至9月中旬,连豆期价持续上涨,并创出2009年以来的新高,随后连豆期价持续在高位窄幅波动,期价整体走势依然强劲。具体来看:1-4月底:自2011年12月中旬以来,在拉尼娜天气的影响下,处于大豆生长期的南美地区遭遇高温干旱天气,导致南美大豆产量大幅减少,大豆供给量骤然下降,国内外大豆期价受此带动

Evaluation of a point-of-care coagulation analyzer for measurement of prothrombin time, activated partial thromboplastin time, and activated clotting time in dogs

OBJECTIVE: To evaluate a point-of-care coagulation analyzer (PCCA) in dogs with coagulopathies and healthy dogs. ANIMALS: 27 healthy and 32 diseased dogs with and without evidence of bleeding. PROCEDURE: Prothrombin time (PT), activated partial thromboplastin time (aPTT), and activated clotting time (ACT) were determined, using a PCCA and standard methods. RESULTS: Using the PCCA, mean (+/- SD) PT of citrated whole blood (CWB) from healthy dogs was 14.5+/-1.2 seconds, whereas PT of nonanticoagulated whole blood (NAWB) was 10.4+/-0.5 seconds. Activated partial thromboplastin time using CWB was 86.4+/-6.9 seconds, whereas aPTT was 71.2+/-6.7 seconds using NAWB. Reference ranges for PT and aPTT using CWB were 12.2 to 16.8 seconds and 72.5 to 100.3 seconds, respectively. Activated clotting time in NAWB was 71+/-11.8 seconds. Agreement with standard PT and aPTT methods using citrated plasma was good (overall agreement was 93% for PT and 87.5% for aPTT in CWB). Comparing CWB by the PCCA and conventional coagulation methods using citrated plasma, sensitivity and specificity were 85.7 and 95.5% for PT and 100 and 82.9% for aPTT, respectively. Overall agreement between the PCCA using NAWB and the clinical laboratory was 73% for PT and 88% for aPTT. Using NAWB for the PCCA and citrated plasma for conventional methods, sensitivity and specificity was 85.7 and 68.4% for PT and 86.7 and 88.9% for aPTT, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: The PCCA detected intrinsic, extrinsic, and common pathway abnormalities in a similar fashion to clinical laboratory tests.     

大豆豆粕:长期看好短期平稳震荡

1 国内大豆市场情况 国庆节后，国产大豆市场逐渐走出了相对低迷的行情。价格在短暂的下跌后迅速上扬，而且较为持续，总体走势先抑后扬（图1），截至11月29日．国内大豆均价为2640元／t，较节前上涨了约246元／t．地区最高涨幅达到300元／t。10月中旬后黑龙江产区大豆收割基本完毕，由于压榨国产豆利润相对较高（外盘连续上涨，进口成本不断攀升），有较强的竞争力，吸引了较多外地油厂进入产区收购大豆，其中南方油厂，期货大豆商也在观望后开始收购，众多收购主体的人市抬高了收购价格，也一度形成了收购积极和农户惜售对峙的局面。11月下旬，国产大豆与进口大豆价差已明显缩减，国内大豆价格以稳为主，局部出现回落。截至11月30日，黑龙江地区油厂大豆入厂价在2440～2500元／t。     

How to extrapolate a withdrawal time from an EHSLC published detection time: A Monte Carlo simulation appraisal

Reason for performing study: For legitimate medications, veterinarians must advise the owners or trainers of horses on appropriate withholding times after a treatment, to avoid the risk of incurring a positive drug test. Objective: To explore the safety span to select that a veterinarian may extrapolate a tailored withdrawal time (WT) from a generic detection time (DT) as published by the European Horserace Scientific Liaison Committee (EHSLC). Methods: Using Monte Carlo simulations, it was shown that for a low variability of pharmacokinetic parameters (CV = 20%), an uncertainty span of about 40% may be selected to transform a mean DT into a WT (i.e. WT = 1.4 DT), which covers 90% of the horse population. In contrast for a highly variable drug (CV = 40%), an uncertainty factor of about 2.1–2.2 needs to be selected, i.e. a WT that is twice the DT. Results: The relative impact of the different factors of variability on the final WT was documented by a so‐called sensitivity analysis. It was shown that the parameters that have the greatest influence on the value of a DT are those that control the terminal half‐life of the drug disposition. In contrast, parameters controlling the level of urine (or plasma) concentrations (i.e. the actual administered dose, the urine‐to‐plasma ratio and the bioavailability) collectively have a minimal influence on the DT. Conclusions and potential relevance: In practice, this means that the main sources of uncertainty are of biological origin and cannot be reduced by any managerial options. The influence of the number of experimental horses that are used by EHSLC to establish a DT was shown that with the standard EHLSC protocol of 6 horses, half of the trials lead to a proposed DT that is equal to or higher than the population 90^th percentile. Increasing the number of investigated horses to 8 and 10 would increase this last probability to 85 and 90%, respectively.
