Our results showed that, compared to conventional vegetable cultivation, plastic greenhouse vegetable cultivation has higher fresh vegetable production, greater CO(2) fixation (3.61 t CO(2) ha(-1) yr(-1)), better soil retention (23.1 t ha(-1) yr(-1)), and requires less irrigation (2132 m(3) water ha(-1) yr(-1)), maintains similar soil fertility, but also has higher NO(3)(-) accumulation and N(2)O

emissions. In 2004. plastic greenhouse vegetable cultivation in China provided an overall net economic benefit of 67,956 yuan yr(-1) (8.28 yuan = 1 USD in 2004), where 68,240 yuan ha(-1) yr(-1) represented ecosystem services and 284 yuan ha(-1) yr(-1) for dis-services. The transition from conventional vegetable cultivation ML323 concentration to plastic greenhouse vegetable cultivation resulted in a net economic benefit of 24,248 yuan ha(-1) yr(-1). A cost-benefit analysis suggests that plastic greenhouse vegetable cultivation in China has the potential to optimize social benefits in addition to increasing annual economic income to farmers directly.

“The (La0.6Ca0.2Sr0.2MnO3)(1-x)(Sb2O3/CuO)(x) (x=0.00, 0.03, 0.07, 0.12 and 0.18) composites were prepared by the solid-state reaction technique. (La0.6Ca0.2Sr0.2MnO3)(1-x)(Sb2O3/CuO)(x)

are identified by X-ray diffraction and SEM analysis as a two phases consisting of ferromagnetic manganite phase and Sb2O3/CuO phase. Magnetic measurement reveals that the Curie temperature as well as the saturation value of magnetization is gradually weakened by Sb2O3/CuO addition. The temperature selleck chemicals INCB28060 supplier dependence of resistivity shows that the

transport behavior of the composites is governed by the grain boundaries. It is suggested that the Sb2O3 addition, acts as a separation layer between grains. Whereas, the introduction of CuO into the grain boundaries forms artificial conducting network and improves the carrier to transport. The maximum magnetoresistance was observed to be approximate to 60% at 10 K for x=0.03 which is larger than the largest MR value of pure La0.6Ca0.2Sr0.2MnO3 (40% at 10 K) in a 2 T magnetic field. Enhanced MR effect at a wide temperature range is consistent with the disorder-driven amplification of spin-dependent transport. (C) 2013 Elsevier Ltd and Techna Group S.r.l. All rights reserved.”
“OBJECTIVE: Adequate dietary iodine intake is necessary for normal thyroid gland function at all times, and most particularly during pregnancy. Increased iodine loss is cited, among other factors, as responsible for the increased iodine demand in this period. Our aim was to compare renal iodine excretion between women during all three pregnancy trimesters with that of their spouses and thereby to estimate the iodine intake in an a large sample of pregnant women in urban areas in Greece.
