Winter wheat is one kind of important crop in China. It’s planting area is one key element to explain yield change. To obtain winter wheat planting area as soon as possible can provide scientific reference for our country’s making related policy. Basing on the cropping system in Shandong province, winter wheat is divided into two kinds “winter wheat sowed by machine-maize” and “people broadcast...

An inventory scheduling model with forbidden time intervals is analyzed The objective is to minimize the long term average cost per time unit Unlike most of the literature on inventory theory no restrictive assumptions are made apriori about the nature of optimal solutions It is rather proved that optimal policies exist and that some of them are cyclic with cycles of a particular structure It i...

Health systems and polices have a critical role in determining the manner in which health services are delivered, utilized and affect health outcomes. 'Health' being a state subject, despite the issuance of the guidelines by the central government, the final prerogative on implementation of the initiatives on newborn care lies with the states. This article briefly describes the public health st...

Most patients with pulmonary arterial hypertension succumb to their disease in the ICU; however, limited evidence-based information exists to guide treatment in those that present with advanced right ventricular failure. Critical care physicians should be aware of the complexities of the treatment of patients with pulmonary arterial hypertension and should develop a strategy for their care. Cur...

High volume production flows are modeled by nonlinear hyperbolic partial differential equations representing conservation laws. These models have Little’s law explicitly built into the formulation. Borrowing from concepts in gas dynamics and vehicular traffic models we derive several prototypical equations representing linear as well as reentrant factories. Multiple products, dispatch polices a...

Ecological priority and green development have become the main theme of times in China. The policy performance evaluation ecological protection needs to quantitatively identify changes ecosystem quality services firstly. This paper constructed analytical framework driven by “Goal-oriented—Policy driven—Ecological quality–Service improvement”, used multi-source data establish approach “ecosystem...

The rusts of wheat are important fungal plant pathogens that can be disseminated thousands of kilometers across continents and oceans by wind. Rusts are obligate parasites that interact with resistance genes in wheat in a gene-for-gene manner. New races of rust develop by mutation and selection for virulence against rust resistance genes in wheat. In recent years, new races of wheat leaf rust, ...

BACKGROUND Identification of wheat sensitization by a skin prick test (SPT) is essential for children with wheat-induced anaphylaxis, since oral food challenge can cause serious adverse effects. Wheat allergens are both water/salt and alcohol soluble. The preparation of wheat extract for SPT containing both water/salt and alcohol soluble allergen is needed. OBJECTIVE To determine if a wheat e...
