This paper reviews the possible causes and effects for no-fault-found observations and intermittent failures in electronic products and summarizes them into cause and effect diagrams. Several types of intermittent hardware failures of electronic assemblies are investigated, and their characteristics and mechanisms are explored. One solder joint intermittent(More)
An outbreak of 81 cases of angiostrongyliasis cantonensis (AC) occurred in Beijing, China, during June through September 2006. Epidemiological characteristics, clinical signs and symptoms, laboratory tests, imaging, and treatment data from the 81 AC patients were collected and analyzed. All cases had a history of eating raw freshwater snails, and acquired(More)
Human ocular angiostrongyliasis caused by Angiostrongylus cantonensis infection in the eye is a very rare condition. Until now, there has been no comprehensive analysis of this disease. We searched and analysed the references found on the Internet that refer to human ocular angiostrongyliasis and reviewed the aetiology, clinical manifestations, diagnosis,(More)
To determine how combination therapy with albendazole and dexamethasone changed cytokine responses in peripheral blood mononuclear cells (PBMC) in patients with eosinophilic meningitis caused by Angiostrongylus cantonensis (EOMA), we measured mRNA levels of Th2 (IL-5, IL-4 and IL-10) and Th1 (IL-2 and IFN-gamma) cytokines with reverse transcription(More)
BACKGROUND/OBJECTIVES Angiotensin-converting enzyme 2 (ACE2), its product angiotensin-(1-7) and its receptor Mas may counteract the adverse effects of the ACE-angiotensin receptor II-AT(1) axis in many diseases. We examined the expression of these novel components of the rennin-angiotensin system in an experimental mouse model of severe acute pancreatitis(More)
RATIONALE, AIMS AND OBJECTIVES Acute fever is the most common clinical symptom for infectious diseases. It is necessary to identify risk factors for infectious patients with acute fever and formulate activation criteria of early warning infectiosity score system (EWIS) to alert outpatient clinic doctors. METHODS Logistic regression analysis was used to(More)
A design of experiments was conducted to determine the reliability of plastic ball grid array packages under various manufacturing and multiple environmental loading conditions. Parameters included conformal coating methods, underfill, solder mask defined and non-solder mask defined pads. Board level temperature cycling, vibration, and combined temperature(More)
Angiotensin-converting enzyme (ACE) and its effector peptide angiotensin II (Ang II) have been implicated in the pathogenesis of pancreatitis. Angiotensin-converting enzyme 2 (ACE2) degrades Ang II to angiotensin-(1-7) [Ang-(1-7)] and has recently been described to have an antagonistic effect on ACE signalling. However, the specific underlying role of ACE2(More)
New construction of fine pitch plastic ball grid array (FBGA) has been investigated through experimentation and physics of failure (PoF) analysis based on the reliability point of view. In this study, a three dimensional FEA model was developed to understand the thermomechanical behavior of FBGA under cyclic thermal loading environments. Experimental(More)
This study investigates the effects of printed circuit board (PCB) material on interconnect durability of lead free assemblies. The assemblies involve soldering various packages (array and peripheral) on to FR4, high glass transition temperature (T g) FR4 and Polyimide (PI) printed circuit boards using Sn3Ag0.5Cu solder alloy. The glass transition(More)
