甘草产业化开发前景不可估量

甘草是宁夏半荒漠草地自然植被的主要组成成分,也是重要的沙生药用植物资源。医疗应用已有近４０００年的历史,被称为草药之王。宁夏野生甘草资源分布面积广,蕴藏量大,种群优势突出,被列入宁夏“五宝”之一。近年来国内外对甘草中有效成分的提取和在抗艾滋病、抗肿瘤、延缓衰老等医药保健功能上的深入研究,使甘草产业化开发前景十分广阔。多年来,由于宁夏对野生甘草的过度采挖,造成草场原生植被和资源破坏严重,并使宁夏原本就十分脆弱的半荒漠草原生态环境更加恶化。甘草蕴藏量急剧减少,资源面临枯竭,品质也呈逐年下降趋势。为了…

Phosphate Rocks and Nuclear Proliferation

Phosphate rocks are predominantly mined for fertilizer production. However, they also contain considerable amounts of accompanying natural uranium that can exceed concentrations found at commercial uranium mines. Extracting uranium from phosphate rocks during fertilizer production is a technically mature process; it was used on an industrial scale in the United States and elsewhere before decreasing uranium prices made this practice unprofitable in the 1990s. Soon, technical improvements, potentially rising uranium prices, and anticipated environmental regulations may make uranium extraction from phosphates profitable again in the United States and emerging phosphate rock mining centers in Northern Africa and the Middle East. Extracting uranium during phosphate fertilizer production is desirable in a way that otherwise lost resources are conserved and fertilizers with reduced radiotoxic heavy metal content are produced. Phosphate rocks have also been subject to clandestine uranium acquisition. In this work, the relevance of unconventional uranium resources from phosphate rocks is reviewed. A brief overview of the extraction process, a list of the required materials, and a very simple estimation of the amounts of uranium that could be extracted using a container-sized pilot plant which can be integrated into existing fertilizer plants is provided. Lastly, past known unreported uranium extraction activities from phosphate rocks are discussed.     

Energy‐efficient scheduling for sustainable manufacturing systems with renewable energy resources

Environmentally friendly energy resources open a new opportunity to tackle the problem of energy security and climate change arising from wide use of fossil fuels. This paper focuses on optimizing the allocation of the energy generated by the renewable energy system to minimize the total electricity cost for sustainable manufacturing systems under time‐of‐use tariff by clipping the peak demand. A rolling horizon approach is adopted to handle the uncertainty caused by the weather change. A nonlinear mathematical programming model is established for each decision epoch based on the predicted energy generation and the probability distribution of power demand in the manufacturing plant. The objective function of the model is shown to be convex, Lipchitz‐continuous, and subdifferentiable. A generalized benders decomposition method based on the primal‐dual subgradient descent algorithm is proposed to solve the model. A series of numerical experiments is conducted to show the effectiveness of the solution approach and the significant benefits of using the renewable energy resources.

Value management of diagnostic equipment with cancelation,no‐show,and emergency patients

Magnetic resonance imaging and other multifunctional diagnostic facilities, which are considered as scarce resources of hospitals, typically provide services to patients with different medical needs. This article examines the admission policies during the appointment management of such facilities. We consider two categories of patients: regular patients who are scheduled in advance through an appointment system and emergency patients with randomly generated demands during the workday that must be served as soon as possible. According to the actual medical needs of patients, regular patients are segmented into multiple classes with different cancelation rates, no‐show probabilities, unit value contributions, and average service times. Management makes admission decisions on whether or not to accept a service request from a regular patient during the booking horizon to improve the overall value that could be generated during the workday. The decisions should be made by considering the cancelation and no‐show behavior of booked patients as well as the emergency patients that would have to be served because any overtime service would lead to higher costs. We studied the optimal admission decision using a continuous‐time discrete‐state dynamic programming model. Identifying an optimal policy for this discrete model is analytically intractable and numerically inefficient because the state is multidimensional and infinite. We propose to study a deterministic counterpart of the problem (i.e., the fluid control problem) and to develop a time‐based fluid policy that is shown to be asymptotically optimal for large‐scale problems. Furthermore, we propose to adopt a mixed fluid policy that is developed based on the information obtained from the fluid control problem. Numerical experiments demonstrate that this improved policy works effectively for small‐scale problems. © 2016 Wiley Periodicals, Inc. Naval Research Logistics 63: 287–304, 2016
