BACKGROUND Delayed gastric emptying (DGE) remains the most frequent complication following pancreatoduodenectomy (PD) with published incidences as high as 61%. The present study investigates the impact of bowel reconstruction techniques on DGE following classic PD (Whipple-Kausch procedure) with pancreatogastrostomy (PG). METHODS We included 168 consecutive patients who underwent PD with PG w...

In an agricultural catchment area in Germany we analyzed water samples from five entry routes for 2 insecticides. 5 fungicides and 13 herbicides. The sewage plant outlet and the emergency overflow of a sewage sewer contained only herbicides. In each farmyard runoff we found on average 24 g pesticides during application period, presumably caused by cleaning the spraying equipment. In comparison,...

A dielectric, slab-symmetric structure for generating and accelerating low-energy electrons has been under study for the past two years. The resonant device is driven by a side-coupled laser and is configured to maintain field profiles necessary for synchronous acceleration and focusing of nonrelativistic particles. Intended applications of the structure include the production of radiation for ...

background: iran is an arid country and has serious limitations in terms of water recourses. in arid and semi-arid regions this problem is more severe. industry is one of the primary water consumers in the country and appropriate determination of industry water demand is on the most important priorities that should be considered to save water consumption as well as determining the industry wate...

Now a days we see that large amount of water has been wasted either in sewage or soil. it suffers from shortage supply for irrigation uses. On the other hand, production system Rajasthan region is characterized by many agricultural food industries, activity which produces amounts wastewater.

The highly elevated concentrations of the rare earth elements and yttrium (REY), U, Mo, Se, Pb in late Permian coals some coalfields Guangxi Province, South China, have been widely investigated; however, mode occurrence enrichment mechanism these critical are still under debate. This study investigates mineralogical geochemical compositions non-coal rocks from Xian’an Coalfield Province to disc...
