Results The incidence of acute pancreatitis was 30.0 per 100 000 population overall, mortality was 6.4% at 60 days. Incidence increased significantly from 27.6 per 100 000 in 1999 to 36.4 in 2010 (average annual increase = 2.7% per year), there was little trend in mortality (0.2% average annual reduction). The largest increases in incidence were among women aged <35 years (7.9% per year) and me...

This paper presents the design and analysis of a liquid refractive index sensor that utilizes a unique physical mechanism of resonant optical tunneling effect (ROTE). The sensor consists of two hemicylindrical prisms, two air gaps, and a microfluidic channel. All parts can be microfabricated using an optical resin NOA81. Theoretical study shows that this ROTE sensor has extremely sharp transmis...

OBJECTIVES To estimate the effects of achieving China's national goals for dietary salt (NaCl) reduction or implementing culturally-tailored dietary salt restriction strategies on cardiovascular disease (CVD) prevention. METHODS The CVD Policy Model was used to project blood pressure lowering and subsequent downstream prevented CVD that could be achieved by population-wide salt restriction in...

1. We extrapolate a new range of estimates of the species richness of Microgastrinae (Hymenoptera: Braconidae) wasps, a diverse group of small parasitoids that attack caterpillars of Lepidoptera. 2. Our estimates, using an array of focal study faunas to provide reasonable bounds for minimum and maximum values, range from 17 000 to 46 000+ species. These calculations make use of a geographically...

CASTING DIE

The paper presents the analysis of thermo-mechanical fatigue cracking of die casting die during industrial use. An innovative, production friendly approach to monitor the surface crack dimensions was introduced, which is based on measuring defect-fi n on the casting part. A new four moulds die casting die was monitored 40 000 cycles in order to complete the production series. The production was...

Roads are land transportation facilities that very important in facilitating economic relations activities, both between one city and another. Good road conditions will facilitate the movement of people relationships other social activities. Meanwhile, if there is damage, it not only hinder but accidents can occur. Many factors cause including weather, weather on surface when rains, scorching h...
