The physiological condition of Mexican fruit flies, Anastrepha ludens (Loew), affected their attraction to 2 similar but qualitatively different synthetic lures in wind-tunnel bioassays. The 2 lures were BioLure (ammonium acetate and putrescine) and AMPu (ammonium carbonate, methylamine HCI, and putrescine) . Effects of food deprivation on attraction to the lures were smaller than the effects o...

폐리튬이온전지를 고온에서 용융환원하면 금속혼합물, 슬라그와 리튬(I)을 함유한 분진이 발생한다. 분진의 침출 합성액을 이용하여 Li2CO3 석출실험을 수행했다. 석출제의 종류와 비수용액의 첨가가 석출에 미치는 영향을 조사했다. (NH4)2CO3에서 해리된 암모늄과 탄산이온의 수화반응으로 인해 Na2CO3가 석출제로서 효과가 우수했다. 또한 용액에 아세톤이나 에탄올을 첨가하면 리튬(I)의 석출률이 증가했다. 특히 (NH4)2CO3을 석출제로 첨가한 조건에서 용액의 pH가 12까지 증가함에 따라 석출률도 동일한 석출조건에서 Na2CO3에 의한 (NH4)2CO3보다 더 높았다.

The zooplankton community structure in Eğirdir Lake (Isparta-Turkey) was studied monthly throughout an annual cycle (January 2010-December 2010). The zooplankton community was represented by three main groups: Rotifera, Cladocera and Copepoda, respectively comprised 89.62%, 7.78% and 2.60% of the total zooplankton abundance. Eğirdir Lake was dominated by the rotifera Polyarthra dolichoptera in ...

Radionuclide and metal contaminants such as Sr are present beneath U.S. Department of Energy (DOE) lands in both the groundwater (e.g., 100-N area at Hanford, WA) and vadose zone (e.g., Idaho Nuclear Technology and Engineering Center at the Idaho National Engineering and Environmental Laboratory). In situ containment and stabilization of these contaminants is a cost-effective treatment strategy...

The application of barium f&:e (BaFelZO19; BaF) in the magnetic media industry requires materials with strict control of homogeneity, morphology and magnetic properties resulting from their preparation and pretreatment. Here the use of water-in-oil microemulsions for the synthesis of nanoparticles of BaF is considered. Two microen~ulsions (containmg an aqueous phase, cetyltrimethylammonium brom...

Kidney stone analysis is the test done on the stone which cause problems when they block the flow of urine through or out of the kidneys. The stones cause severe pain and are also associated with morbidity and renal damage. There is also no clear understanding on the relative metabolic composition of renal calculi. Hence, the study is aimed to find out the chemical composition of it which can g...

Bioerosion by Cliona delitrix and Cliona lampa was assessed at 43 sites along the Florida Reef Tract, USA, in the summer of 2001. Sponge abundances were estimated using rapid visual assessment. Tissue samples of sponges were taken for analysis of delta15N. Comparison samples were taken from Belize. Annual trends in sponge abundance were estimated from archived videos covering the period from 19...

agal2o3 nanocomposite were synthesized by solution combustion technique using ammonium carbonate as a new fuel under simultaneous combustion of alumina and silver particles condition. samples prepared with different amount of silver, were characterized by xrd, bet, sem and optical absorption measurements. xrd analysis was used to determine the change in phase and size of the synthesized nanopar...
