The Amazonian Craton comprises an Archean domain surrounded by four successively younger Proterozoic tectonic provinces. Within the Rio-Negro-Juruena province the serra da Providencia Intrusive suite （1.60 and 1.53 Ga） consists of A-type rapakivi gran- ites, charnockites and mangerites genetically associated with diabase dikes, gabbros and amphibolites. The original mafic melts were derived from a depleted mantle source （εN（T）＋2.5 to ＋2.8;εsr（T） -12.1）. underplated mafic magma induced melting of a short-lived felsic crust, thus originating coeval felsic-mafic magmatism in a conti- nental intraplate setting. The Colorado Complex, assigned to the Rondonian-san Ignacio province, comprises 1.35-1.36 Ga intrusive bimodal magmatism represented by monzonite gneisses associated with amphibolite, gabbro and metadiabase dikes intercalated with metasediments with detrital zircon that yield u- Pb ages of 1.35 to 1.42 Ga. Mafic samples dis- play juvenile signatures （εNd（T） 0.0 to ＋5.2; εsr（T） --5.0 to --30.7） and are less contaminated than the serra da Previdencia and Nova Brasilandia ones. The generation of the basaltic magma is related to the subduction of an oceanic slab below the peridotite wedge （intraoceanic arc setting）. Fluids and/or small melts from the slab impregnated the mantle. The Nova Brasilandia sequence （sunsas-Aguapef province） comprises a metasedimentary sequence intruded by 1.10-1.02 Ga metadia- bases, gabbros, meta-gabbros, and amphibolites associated with granitic plutons （bimodal mag- matism）. The original tholeiitic magmas, derived from a depleted source （εNd（T） = ＋3.1 to ＋5.0）, in a proto-oceanic setting, underwent subsequent contamination by the host rocks, as indicated by the isotopic and trace element data.

Measuring Capacity for Resilience among Coastal Counties of the u. s. Northern Gulf of Mexico Region

引用

American Journal of Climate Change 2012年第4期1卷 194-204页

作者： Margaret A. Reams Nina s. N. Lam Ariele Baker Department of Environmental sciences Louisiana State University Baton Rouge USA

Many have voiced concern about the long-term survival of coastal communities in the face of increasingly intense storms and sea level rise. In this study we select indicators of key theoretical concepts from the social-ecological resilience literature, aggregate those indicators into a resilience-capacity index, and calculate an index score for each of the 52 coastal counties of Louisiana, Texas, Mississippi, Alabama and Florida. Building upon Cutter’s social Vulnerability Index work [1], we use Factor Analysis to combine 43 variables measuring demographics, social capital, economic re- sources, local government actions, and environmental conditions within the counties. Then, we map the counties’ scores to show the spatial distribution of resilience capacities. The counties identified as having the highest resilience capaci- ties include the suburban areas near New Orleans, Louisiana and Tampa, Florida, and the growing beach-tourist com- munities of Alabama and central Florida. Also, we examine whether those counties more active in oil and gas develop- ment and production, part of the region’s “energy coast”, have greater capacity for resilience than other counties in the region. Correlation analyses between the resilience-capacity index scores and two measures of oil and gas industry ac- tivity (total employment and number of business establishments within five industry categories) yielded no statistically significant associations. By aggregating a range of important contextual variables into a single index, the study demonstrates a useful approach for the more systematic examination and comparison of exposure, vulnerability and capacity for resilience among coastal communities.

Potential annual daylighting performance of a high-efficiency daylight redirecting slat system

While the primary role of window attachments is often to moderate glare and solar heat gains,they are also able to provide additional daylight to interior *** this purpose,a variety of daylight-redirecting window systems have been developed over the past 150 *** reflective systems(slats/light shelves)or prismatic systems that rely on total internal reflection work well under specific solar conditions,but generally sacrifice performance over a much wider range of incident solar angles and sky *** systems-typically reflective slats-are more responsive to sun angles but have not been able to achieve optimal performance for glare and daylight redirection efficiency.A previous investigation into an adjustable,reflective blind concept first conceived of in the late 1970s showed promise but was not reduced to practice due to lack of adequate simulation and analysis *** this paper,this concept is further developed and its energy and visual comfort performance evaluated for four mid-latitude,temperate climates using ray-tracing simulation *** indicate significant potential lighting energy savings when compared with conventional automated reflective blinds(2.1-4.9 kWh/(m^(2)·a),or 14%-42%,depending on climate and orientation)or,especially,manually-operated matte white Venetian blinds(1.4-7.9 kWh/(m^(2)·a),or 9%-54%,depending on climate and orientation),while maintaining acceptable or better visual comfort conditions throughout the interior space.

第十七届全国化学热力学和热分析学术会议

作者： L.zheng W.Guan College of Chemistry Liaoning University

As a new generation of functional ionic liquid, amino acid ionic liquids（AAILs） have the ability to form strong hydrogen bonds, dissolving the DNA, cellulose and other carbohydrates, so it can be widely used as chiral solvents and new functional materials in life science research and the pharmaceutical industry. This paper we report that the enthalpies of solution and the density for [C4mim][Ala] were measured at（288.15 to 308.15 ± 0.01） K with an interval of 5 K by a solution-reaction isoperibol calorimeter and an Anton Paar DMA 4500 oscillating u-tube densitometer. The values of the standard molar enthalpy, ΔsolHmθ, and the apparent relative molar enthalpy, φL, of solution for [C4mim][Ala] were obtained in terms of Archer’s method. The standard molar heat capacity of solution, ΔCp,mθ = 590 J·K-1·mol-1, for [C4mim][Ala] was obtained from the slope of the straight line of ΔsolHmθ vs.（T – 298.15） K. The apparent relative molar heat capacity of various molalities [C4mim][Ala] were estimated by Archer’s theory and Paulechka’s method. In addition, the hydration enthalpy of the alanine anion [Ala]-, ΔH–（[Ala-]） = – 395 k J·mol-1, is obtained. The values of standard molar enthalpies of solution and the density for [C4mim][Ala] are listed in following table: T / K 288.15 293.15 298.15 303.15 308.15 –ΔsolHmθ / k J·mol-1 63.08 ± 0.04 59.99 ± 0.05 56.47 ± 0.03 54.00 ± 0.04 51.33 ± 0.04 ρ/g·cm-3 1.09951 1.09634 1.09317 1.08998 1.08998
