针对含混合式抽水蓄能电站的梯级水库发电调度的维数灾问题,在考虑历史径流序列随机性和非线性特点的基础上,建立含混合式抽水蓄能电站的梯级水库长期优化调度模型。文中以调度期内混合式抽水蓄能电站梯级水库发电量最大为目标函数,引入改进社会情态优化(SEOA)算法编程求解。仿真结果表明,新方法在混合式抽水蓄能电站梯级水库发电优化调度问题中既能减少传统算法的冗余计算,又可有效地结合决策者的主观偏好和利益倾向。对比动态规划算法,新方法在较短时间内得到年发电量为66.96×10^8kWh的高质量解。

病毒感染是二十一世纪面临的主要医学挑战之一，从影响全球3％人口的丙肝病毒（HCV）流行病到最近爆发的西尼罗河病毒、寨卡病毒和埃博拉病毒感染。病毒缺乏进行自我复制所需的基础代谢机制。为了解决这个问题，它们劫持它们的宿主的代谢机制以便完成它们的生命周期和进行增殖。然而，科学家们仍然并没有很好地理解病毒与它们感染的有机体之间在代谢上的相互作用。这主要是因为人基因与代谢过程之间存在复杂的相互作用。

A field experiment was carried out in a coastal savannah agro-ecological zone of Ghana to assess the dynamics of stored soil water and actual evapotranspiration (AET) of three maize genotypes (Obatanpa, Mamaba, and Golden Crystal) grown under rainfed conditions. Access tubes were installed to a depth of 120 cm for soil water content monitoring using a neutron probe meter. The soil water balance model of plant root zone was used to estimate AET at different crop growth stages. On average, the rate of AET for Obatanpa, Mamaba, and Golden Crystal maize genotypes were estimated as 4.32, 4.46, and 3.72 mm·day–1, respectively, for the major cropping season as against corresponding values of 3.88, 4.00 and 3.72 mm day–1 for the minor cropping season. Mamaba had higher values of AET from 42 DAE (days after emergence) to 84 DAE during the minor cropping season while it had low AET values during the major cropping season. The positive balance in stored soil water in the root zone of Obatanpa was the highest from 42 DAE to 84 DAE followed by Mamaba and Golden Crystal during the major cropping season. Mamaba, on the other hand, had the highest AET from 70 DAE to 84 DAE. Obatanpa used 55.6% of stored soil water for AET, which was the highest among the maize genotypes during the major cropping season. Golden Crystal and Mamaba followed with 53.3% and 51.5%. For the minor cropping season, 48.5% of stored soil water was used by Mamaba for AET, followed by Obatanpa, (46.4%) and Golden Crystal (43.2%). A strong positive significant (p ≤ 0.05) linear correlation existed between AET and precipitation with the coefficient of determination (R2) being 69.2 for Obatanpa, 88.5 for Mamaba and 82.8 for Golden Crystal for the major cropping season. Higher R2 values (98.0, for Obatanpa, 94.1 for Mamaba and 98.9 for Golden Crystal) were, however, obtained for the minor cropping season. Additionally, a strong linear relationship was found between AET and precipitation, suggesting the need to form

The wild type maize genotype, B73, is not amenable for callus production and an efficient protocol for B73 maize callus induction has never been reported up-to-date. Scientific efforts in producing B73 maize callus using all known callus inducible media have been unsatisfactory. Here we developed and described an efficient protocol for callus induction from B73 maize seedlings. The protocol is based on well known callus inducible media CM4C where we have sequentially subtracted some chemical compounds and added some new compounds mediating cell proliferations. This newly described protocol was able to induce callus production in a wide range of crop species including rice and soybean. We found that cell proliferation factors, NAA (auxin analog) and 2,4 D (auxin influx carrier) were not only very crucial but required for positive B73 maize callus induction. The absence of one or the other will lead to the failure of B73 maize callus production. The well known CM4C callus induction composition lacks NAA. Our findings will advance genetic studies of maize mutants generated from B73 genotype background.

AIM To study the early postoperative intensive care unit(ICU) management and complications in the first 2 wk of patients undergoing cytoreductive surgery(CRS) and hyperthermic intraperitoneal chemotherapy(HIPEC).METHODS Our study is a retrospective, observational study per-formed at Icahn School of Medicine at Mount Sinai, quaternary care hospital in New York City. All adult patients who underwent CRS and HIPEC between January 1, 2007 and December 31, 2012 and admitted to ICU postoperatively were studied. Fifty-one patients came to the ICU postoperatively out of 170 who underwent CRS and HIPEC therapy during the study period. Data analysis was performed using descriptive *** Of the 170 patients who underwent CRS and HIPEC therapy, 51(30%) came to the ICU postoperatively. Mean ICU length of stay was 4 d(range 1-60 d) and mean APACHE Ⅱ score was 15(range 7-23). Thirtyone/fifty-one(62%) patients developed postoperative complications. Aggressive intraoperative and postoperative fluid resuscitation is required in most patients. Hypovolemia was seen in all patients and median amount of fluids required in the first 48 h was 6 L(range 1-14 L). Thirteen patients(25%) developed postoperative hypotension with seven requiring vasopressor support. The major cause of sepsis was intraabdominal, with 8(15%) developing anastomotic leaks and 5(10%) developing intraabdominal abscess. The median survival was 14 mo with 30 d mortality of 4%(2/51) and 90 d mortality of 16%(8/51). One year survival was 56.4%(28/51). Preoperative medical co morbidities, extent of surgical debulking, intraoperative blood losses, amount of intra op blood products required and total operative time are the factors to be considered while deciding ICU vs non ICU *** Overall, ICU outcomes of this study population are excellent. Triage of these patients should consider preoperative and intraoperative factors. Intensivists should be vigilant to aggressive postop fluid resuscitation,

Background: Maintenance of optimal Endotracheal Tube cuff Pressure (ETTcP) in anaesthetic practice reduces cuff pressure complications. Aneroid manometers for measurement of ETTcP are not widely available in Ghana, hence anaesthesia providers estimate ETTcP according to their experience. The study assessed ETTcP obtained from estimation techniques between anaesthesia providers at Korle-Bu Teaching Hospital (KBTH). It also evaluated the Volume of Air Required (VAR) to obtain an acceptable cuff inflation pressure for sizes 7.0 and 8.0 mm adult endotracheal tubes used at the hospital, and the effect of patient’s age, weight and height on this volume. Methods: Eighty-one patients who underwent general anaesthesia were recruited. ETTcP was measured using an aneroid manometer via a three-way tap. After full cuff deflation, the cuff was refilled with air until an ETTcP of 20 cm H2O was obtained. Independent t-test was used to measure the statistical variations in the ETTcP using estimation techniques in relation to recommended levels as well as the significant difference of mean VAR to obtain a cuff pressure of 20 cm H2O. Grouped t-test was used to determine significant differences in ETTcP between anaesthesia providers using estimation techniques. Results: Mean ETTcP obtained from estimation techniques was (61.87, 73.79) cm H2O. The mean ETTcP measured for Physician and Nurse Anaesthetists were 65.36 cm H20 and 69.52 cm H2O respectively. The mean VAR to achieve an ETTcP of 20 cm H2O for endotracheal tube sizes 7.0 mm and 8.0 mm were 3.90 ± 1.13 mls and 4.55 ± 0.95 mls respectively. Age and weight significantly influenced the VAR to achieve a cuff pressure of 20 cm H2O, however, height did not. Conclusions: This study demonstrated that cuff pressures obtained by estimation techniques were generally higher than the recommended average with no significant difference between anaesthesia providers. However, in the absence of an aneroid manometer, ETTcP of tube sizes 7.0 mm and
