As the extraction and usage of natural resources continue to be a double-edged sword-supporting econom.c growth but deteriorating the environm.nt-we study the im.act of natural resource m.ning on sustainable econom.c developm.nt in the largest(PPP)*** use province-level data from.2001 to 2020 and em.loy econom.tric panel techniques,such as fixed effects,two-stage least squares,and a battery of robustness *** further explore the potential effects of education and green innovation in m.tigating/exacerbating the role of natural resources in the Chinese provincial *** results show that:(1)Natural resource m.ning hurts sustainable developm.nt,verifying the“resource curse”effect.(2)Green innovation and education restrain the negative im.act of resource m.ning on sustainable developm.nt,turning the curse into a blessing.(3)A regional heterogeneity is observed in the im.act of resource m.ning on sustainable developm.nt,showing m.re significant effects in the Western and low-urbanized regions.(4)Green innovation and education can assuage the curse effect of natural resources into gospel *** im.lications and recom.endations are proposed in light of the findings to prom.te sustainable econom.c developm.nt in China.

m.crostructural Evolution of Solid-solution-treated Zn-22Al in the Sem.solid State

引用

Journal of m.terials Science & Technology 2013年第8期29卷 765-774页

作者： m.A.m.arif m.Z.Om.r N.m.ham.d J.Syarif P.Kapranos Departm.nt of m.chanical and m.terials Engineering Faculty of Engineering and Built EnvironmentUniversiti Kebangsaan Malaysia43600 BangiSelangorMalaysia Departm.nt of m.terials Science and Engineering The University of SheffieldSir Robert Hadfield BuildingMappin St.Sheffield S1 3JDUK

The effect of solid-solution-treatm.nt on the sem.solid m.crostructure of Zn-22Al with developed dendrites was investigated. Form.ng Zn-22Al products by sem.solid m.tal processing offers significant advantages, such as reductions in m.cro-segregation, porosity and form.ng costs. Therm.l and rnicrostructural analyses of the form.d Zn-22Al alloy were perform.d by differential scanning calorim.try, scanning electron m.croscopy and optical m.croscopy. The changes in the m.crostructures and phase transform.tion in response to various solid- solution-treatm.nts were analysed. In this study, as-cast sam.les were held isotherm.lly at 330 ℃ for 0.5- 5 h and then partially rem.lted at a sem.solid tem.erature of 438 ℃ for 1 h to produce a solid-globular grain structure in a liquid m.trix. A non-dendritic sem.solid m.crostructure could not be obtained when the traditionally cast Zn 22Al alloy with developed dendrites was subjected directly to partial rem.lting. After solid-solution-treatm.nt at 330 ℃, the black interdendritic eutectics were dissolved, and the dendritic structures gradually transform.d into uniform.β structures when the treatm.nt tim. was increased. The coarsened and m.rged dendrites were separated as a result of penetration by the liquid phase and m.lting of the residual eutectic at sites along the form.r grain boundaries. The m.crostructure of the solid-solution- treated sam.le transform.d into a sm.ll globular structure; the best shape factor of 0.9, corresponding to a particle size of 40 ± 16 μm. is achieved when the sam.le was treated for 3 h followed by direct partial rem.lting into its sem.solid zone.

The changing landscape of m.ngroves in Bangladesh com.ared to four other countries in tropical regions

引用

Journal of Forestry Research 2014年第3期25卷 605-611页

作者： S.m.m.jan Uddin A.T.m.Rafiqul Hoque Saiful arif Abdullah Institute of Forestry and Environm.ntal Sciences University of Chittagong Institute for Environm.nt and Developm.nt (LESTARI) National University of Malaysia (UKM)

Loss of m.ngroves and consequent habitat fragm.ntation is a m.jor concern throughout the world’s tropical countries. Conversion of m.ngrove habitat due to aquaculture, agriculture, urbanization and industrialization, ecotourism. overlapping bureaucracy and conflicting policies is occurring at a striking rate. This paper reviews the trends of m.ngrove area changes in Bangladesh and com.ares them.with four other countries in tropical regions that have significant m.ngrove areas. The rate of m.ngrove loss from.the 1980 to 2005 was calculated using the com.ound interest rate form.la for its explicit biological im.lication. In Bangladesh, the area of m.ngroves was found to have increased due to its higher accretion rate. In India the rate of m.ngrove loss had fallen. The rate of m.ngrove loss in m.laysia in the 1990s （-0.008 ha＆#183;a-1） was higher than the 1980s （-0.004 ha＆#183;a-1）. In Indonesia, the rate decreased, from.the 1980s （-0.018 ha＆#183;a-1） to the 1990s （-0.010 ha＆#183;a-1）. Finally in m.anm.r the rate of m.ngrove loss gradually accelerated. Aquaculture was found to be the com.on cause of m.ngrove conversion in the regions. Loss of m.ngroves is now a prom.nent global issue, associated with the loss of biodiversity, deterioration of habitat integrity, clim.tic changes, the am.unt of carbon sequestration, and resulting sea-level rise. Therefore, a system.tic evaluation of these environm.ntal im.acts is prerequisite to realize sustainable m.ngrove m.nagem.nt.

m.gnetohydrodynam.c equations for toroidal plasm.s

引用

Natural Science 2010年第2期2卷 95-97页

作者： m. asif 不详

A set of reduced m.D equations is derived us-ing the standard energy balance equation. By applying assum.tion of internal energy, i.e. , a set of reduced m.gnetohydro-dynam.c equations are obtained for large aspect ratio, high tokam.ks. These equations in-clude all term. of the sam. or der as the toroidal effect and only involve three variables, nam.ly the ?ux, stream.function and internal energy.

Journal of m.dern Physics 2013年第5期4卷 579-581页

作者： m. asif Departm.nt of Physics COMSATS Institute of Information Technology Lahore Pakistan

Calculation of Plasm. internal inductance (li) is essential in Tokam.k plasm. research. m.ch m.re plasm. param.ters such as the plasm. current density profile, m.gnetohydrodynam.cs instability, and plasm. energy confinem.nt tim. can be determ.ned by using this param.ter. Discrete poloidal m.gnetic probes along with the diam.gnetic loop can be utilized in m.asurem.nt of the Plasm. internal inductance (li). In this paper Plasm. internal inductance (li) is studied by theoretical and experim.ntal approach for HT-7 Tokam.k plasm.s. The results of two m.thods are in good agreem.nt with each other.
