干草晒制达到打捆的安全含水量所需要的时间比晴天的持续时间长,因此从牧草收割到可以贮存这段时间往往遇到下雨。在某一天降雨时段、空气的干燥程度对干草含水量的影响最大,其次是饲料作物的种类及其生长阶段,收割时所采用的方法等,最... 详细信息

干草晒制达到打捆的安全含水量所需要的时间比晴天的持续时间长,因此从牧草收割到可以贮存这段时间往往遇到下雨。在某一天降雨时段、空气的干燥程度对干草含水量的影响最大,其次是饲料作物的种类及其生长阶段,收割时所采用的方法等,最近已提出了预报干草晒制时间的有效方法。大多数的资料表明;干草的干燥速度可以近似地表示成饱和水汽压差或累积潜在蒸发的指数函数。本文利用苜蓿+狐茅,猫尾草+苜蓿、鸡脚草、雀麦和狐茅的大田资料,比较预报千草制作时间的各种方法,结果表明。通过选用适当的作物系数,累积潜在蒸发的方法预报结果最准确。

Background.Though engaging patients with atrial fibrillation(AF) in und.rstand.ng their stroke risk is encouraged.by guid.lines, little is known regard.ng AF patients' perceived.stroke risk or its relationship with oral anticoagulation(OAC) use. We aim to id.ntify factors associated.with und.restimation of stroke risk among old.r patients with AF and.relate this to OAC use. Method. d.ta are from the ongoing SAGE(Systematic Assessment of Geriatric Elements)-AF stud., which includ.d.old.r patients(> 65 years) with non-valvular AF and.a CHA2 d.2-VASc score of ≥ 2. Participants reported.their perceived.risk of having a stroke without OAC. We compared.the perceived.risk to CHA2 d.2-VASc pred.cted.stroke risk and.classified.participants as "over" or "und.r" estimators, and.id.ntified.factors associated.with und.restimation of risk using multiple logistic regression. Results The average CHA2 d.2-VASc score of 915 participants(average age: 75 years, 47% female, 86% white) was 4.3 ± 1.6, 43% of participants had.d.scord.nt pred.cted.and.self-reported.stroke risks. Among the 376 participants at highest risk(CHA2 d.2-VASc score ≥ 5), 46% of participants und.restimated.their risk. Old.r participants(≥ 85 years) were more likely and.OAC treated.patients less likely to und.restimate their risk of d.veloping a future stroke than respective comparison groups. Conclusions A significant proportion of stud. participants misperceived.their stroke risk, mostly by overestimating. Almost half of participants at high risk of stroke und.restimated.their risk, with old.r patients more likely to d. so. Patients on OAC were less likely to und.restimate their risk, suggesting that successful efforts to ed.cate patients about their stroke risk may influence treatment choices.

Integrated.mod.lling, well correlation and.petrophysical analysis were performed.to characterize the reservoirs for optimum hyd.ocarbon correlation using 3-d.seismic reflection d.ta and.suites of well logs from Ataga 5, 7, 10 and.11 wells respectively in Ataga field. shallow offshore, Niger d.lta Basin, Nigeria. The stud. revealed.the presence of two viable hyd.ocarbon bearing reservoirs, AT1 and.AT2 and.the average values of porosity, permeability, water saturation, hyd.ocarbon saturation, Net to Gross (NTG) and.volume of shale are in the ranges of 15% - 77%, 44.5% - 75.5%, 25.5% - 85%, 15% - 75.5%, 0.70 - 0.88 and.0.11 - 0.38 respectively which goes further to show that the both reservoirs have fair characteristics that are suggestive of the presence of hyd.ocarbon accumulation. It can therefore be d.d.ced.that the permeability values are reflective of fair interconnectivity of pore spaces of sand. within the well areas and.their ability to transmit fluid., the d.pth and.d.pth structural map generated.for the horizons and.structures shows that the most d.minant trapping mechanism in the area und.r stud. is the crescentic growth fault and.the rollover anticlines trend.ng in the Northwest-Southeast d.rection and.from the volumetric analysis. It can be d.d.ced.that the recoverable gas for AT1 and.AT2 reservoirs is 2 × 106 mscf and.6 × 106 mscf respectively.
