Residual interaction effects on deeply bound pionic states in Sn and Pb isotopes

We have studied the residual interaction effects theoretically on the deeply bound pionic states in Pb and Sn isotopes. We need to evaluate the residual interaction effects carefully in order to deduce the nuclear medium effects for pion properties, which are believed to provide valuable information on nuclear chiral dynamics. The s- and p-wave $\pi-N$ interactions are used for the pion-nucleon residual interactions. We show that the complex energy shifts are around [(10-20)+i(2-7)]keV for 1s states in Sn, which should be taken into account in the analyses of the high precision data of deeply bound pionic $1s$ states in Sn isotopes.Comment: REVTEX4, 6 pages, 5 tables, Submitted to Phys.

Thinning practices in rehabilitated mangroves: Opportunity to synergize climate change mitigation and adaptation

Mangrove trees act important roles in the coastal ecosystems, protecting community against high-tide and\ud storms, controlling land erosion and providing fish breeding ground. In the last few decades, the massive area has\ud devastated due to commercial shrimp and fish ponds development. To rehabilitate the coastal ecosystems, some\ud mangrove has been planted with spacing distances of 1x1 m with minimal forest management. Those dense-spaced\ud stands enhanced light competitions and inhibit growth. These poor quality and immature stands that reach an early\ud climax in 10-15 years were observed in two adjacent sites near Nam Dinh and Thanh Hoa in northern Vietnam, where\ud Kandelia candel were planted. To cultivate the resurgent stands and increase their growth, thinning mangrove is\ud essential. Stand densities of the mangrove trees with and without the thinning practice were 17,800 and 5,200 trees ha-1,\ud respectively. Their potential of the maximum above-ground biomass were 303 and 239 Mg ha-1, respectively. However,\ud quality of the single tree was largely different whether or not thinning practice is conducted, as the thinned one of 46 kg\ud tree-1 was about three times higher than the non-thinned of 17 kg tree-1. The thinning practice enhances stand biomass\ud growth with improved growth condition in the forest, which advances carbon sequestration for the climate change\ud mitigation. The cultivated trees also ensure the climate change adaptation of coastal protection, fishery products and\ud bio-diversity. Synergizing mitigation and adaptation strategies with the mangrove thinning would enhance the benefits\ud for coastal communities most vulnerable to climate change

Nitric Oxide Circumstances in Nitrogen-Oxide Seeded Low-Temperature Powling-Burner Flames

Flat low-temperature two-stage flames were established on a Powling burner using rich diethyl-ether/ air or n-heptane/air mixtures, and nitrogen monoxide NO was added into the fuel-air mixtures with a concentration of 240 ppm. The temperature development and chemical-species histories, especially of NO, nitrogen dioxide NO2 and hydrogen cyanide HCN were examined associated with an emission-spectrum measurement from the low-temperature flames. Nitrogen monoxide was consumed in the cool-flame region, where NO was converted to the NO2. The NO2 generated, however, fell suddenly in the cool-flame degenerate region, in which the HCN superseded. In the blue-flame region the NO came out again and developed accompanied with remained HCN in the post blue-flame region. The NO seeding into the mixture intensified the blue-flame luminescence probably due to the cyanide increase

Fabrication of ZnSnP(2) thin films by phosphidation

ZnSnP(2) is a promising candidate as a solar absorbing material consisting of earth-abundant and low-toxic elements. In this study, the phosphidation method, where co-sputtered Zn–Sn thin films react with phosphorus gas, was adopted for fabricating ZnSnP(2) thin films. To establish the conditions for producing ZnSnP(2) thin films, we investigated the influence of phosphidation temperature on the product phases, and interpreted the experimental results using chemical potential diagrams of the Zn–Sn–P system. ZnSnP(2) thin films with a single phase were obtained by phosphidation at 500 °C under a phosphorus vapor pressure of 10[−2] atm. However, formation of ZnSnP(2)protrusions was observed on the surface of the thin films. Based on the experimental results and the chemical potential diagrams, it is indicated that un-reacted liquid Sn particles reacted with Zn and phosphorus gas to form ZnSnP(2) protrusions in a manner similar to the vapor-Liquid-Solid growth mode
