BACKGROUND The diagnosis of pleural tuberculosis (TB) remains to be difficult. Interferon-gamma release assay (IGRA) is a promising method for diagnosing TB in low TB burden countries. The release of interferon-gamma (IFN-γ) by T lymphocytes increases at a localized site of infection with Mycobacterium tuberculosis antigen. This study aimed to examine the(More)
The paper proposes a deterministic node deployment method based on grid scan to achieve targets coverage and nodes connectivity. Target area is divided into girds from which the most suitable one is selected to place the next node. In the coverage phase, the grid where the sensor node can sense the most targets and have the best coverage level is selected(More)
Solar greenhouses are well-established and very popular in the north of China as a way of meeting the demand for fresh local winter vegetables. Nonetheless, they are more susceptible to meteorological disasters, such as fog, haze and cold temperatures. A meteorological risk management system that includes disaster forecasting and control is a useful tool to(More)
The aim of this study was to examine the performance of T-SPOT.TB on cerebrospinal fluid (CSF) and peripheral blood (PB) in diagnosis of tuberculous meningitis (TBM) in China. Of 100 patients with presumed TBM prospectively enrolled from Sep 2012 to Oct 2014, 53 were TBM (21 definite and 32 probable TBM cases) and 37 were non-TBM cases; the other 10(More)
The diagnosis of extrapulmonary tuberculosis (EPTB) is challenging due to non-specific symptoms, invasive approach for specimen collection and most importantly, the paucibacillary status. The objective of this assay was to evaluate the efficacy of Myco/F lytic system, BACTEC Mycobacteria Growth Indicator Tube (MGIT) 960 system and Lowenstein-Jensen (L-J)(More)
In apple cultivation, simulation models may be used to monitor fruit size during the growth and development process to predict production levels and to optimize fruit quality. Here, Fuji apples cultivated in spindle-type systems were used as the model crop. Apple size was measured during the growing period at an interval of about 20 days after full bloom,(More)
The agricultural products' production link, the production antecedents data is the foundation of the traceability system. In the process of agricultural products' production antecedents acquisition, according to the fact that the single acquisition method, the low collection efficiency, and the antecedents data was easy to tamper. This paper designs an(More)
The integrated management of cucumber (Cucumis sativus L.) diseases play a key role in guaranteeing the high quality and security of cucumber production in greenhouse, moreover, the early warning of cucumber diseases is the chief precondition for IPM (Integrated Pest Management). This paper describes an attempt to develop an early warning system for(More)
The integrated management of Good Agricultural Practices (GAP) for cucumber (Cucumis sativus L.) plays a key role in guaranteeing the high quality and safety of cucumber production. This paper describes an attempt to develop a web-based GAP management information system for cucumber. Through applying the system methodology and mathematical modeling(More)
