Project 2.7 Leveraging R&D Investment for the Australian built environment : Phase 2 Case Study Report Part 3 - Green Buildings

This report discusses findings of a case study into "Green Buildings" undertaken as a part of the retrospective analysis component of Sustainable Built Environment National Research Centre (SBEnrc) Project 2.7 Leveraging R&D investment for the Australian Built Environment. The Western Australian Government (WAG) has taken a leadership role for a number of decades in developing more environmentally responsive buildings. In the past decade, considerable initiatives have been introduced to contribute to: (i) greening the stock of government buildings; and (ii) providing leadership in the development of other non-residential buildings developed commercially. This role has been informed by global, national and internal initiatives and research in this area. This case study investigates: (i) the nature of this leadership; and (ii) the role of R&D policy development; and (iii) the dissemination and impact of outcomes in the broader industry. This case study should be read in conjunction with Part 1 of this suite of reports.

3-D kinematical conservation laws (KCL): Evolution of a surface in R-3 - in particular propagation of a nonlinear wavefront

3-D KCL are equations of evolution of a propagating surface (or a wavefront) Omega(t), in 3-space dimensions and were first derived by Giles, Prasad and Ravindran in 1995 assuming the motion of the surface to be isotropic. Here we discuss various properties of these 3-D KCL.These are the most general equations in conservation form, governing the evolution of Omega(t) with singularities which we call kinks and which are curves across which the normal n to Omega(t) and amplitude won Omega(t) are discontinuous. From KCL we derive a system of six differential equations and show that the KCL system is equivalent to the ray equations of 2, The six independent equations and an energy transport equation (for small amplitude waves in a polytropic gas) involving an amplitude w (which is related to the normal velocity m of Omega(t)) form a completely determined system of seven equations. We have determined eigenvalues of the system by a very novel method and find that the system has two distinct nonzero eigenvalues and five zero eigenvalues and the dimension of the eigenspace associated with the multiple eigenvalue 0 is only 4. For an appropriately defined m, the two nonzero eigenvalues are real when m > 1 and pure imaginary when m < 1. Finally we give some examples of evolution of weakly nonlinear wavefronts.

Am unexpected entry into the silver(I) chemistry of diphosphazane ligands: Crystal and molecular structures of [Ag{Ph2PN(Pr-i)PPh2}(CF3SO3)](2), [Ag{Ph2PN(Pr-i)PPh(OC6H3Me2-2,6)}(2)]PF6, and [Ag-3(mu-Cl)(2){Ph2PN(R)PPh2}(3)]PF6 (R = H, Pr-i)

Mononuclear, binuclear and trinuclear silver(l) complexes were obtained unexpectedly while probing the reactivity of diphosphazane ligands of the type X2PN(Pr-i)PXY towards the ruthenium-based precursor Ru(bipy)(2)Cl-2 center dot 2H(2)O, in the presence of a silver salt as a chloride scavenger. Subsequently, the reactions of AgX [X = Cl, NO3 or CF3SO3] with Ph2PN(R)PPh(Y) [R = H, Y = Ph; R = Pr-i, Y = Ph or OC6H3Me2-2,6] in a 1: 1 or 1:2 molar ratio have been investigated. Mononuclear or binuclear Ag(I) complexes containing either chelating or bridging diphosphazane ligands are obtained. Trinuclear silver(l) complexes are accessible by the treatment of diphosphazane ligands, Ph2PN(R)PPh2 [R = H, Pr-i] with AgCl using piperidine as the solvent. In the presence of a suitable chloride donor species, the mononuclear and binuclear complexes of Ph2PN(Pr-i)PPh2 are transformed slowly to the trinuclear complex [Ag-3(mu-Cl)(2){Ph2PN(Pr-i)PPh2}(3)]X, over a period 20 h. The structures of representative complexes have been confirmed by X-ray crystallography and the salient structural features are discussed

Thiosemicarbazones are having the ability to bind with metal and inhibit the enzyme ribonucleoside diphosphate reductase(RDR),an enzyme which is involved in the synthesis of DNA precursors in the mammalian cells.The title compound N-methyl-t-3-methyl-r-2, c-6-diphenylpiperidin-4-one thiosemicarbazone (NMMDPT), CCDC 218052, was prepared using Mannich reaction and characterized by X-ray diffraction methods.The crystal data are:C20H24N4S; M.W= 352.49, triclinic,space group P (1) over bar, a = 8.467(2)angstrom, b = 10.228(2)angstrom, c = 12.249(2)angstrom; lpha=92.595(3)degrees, beta=104.173(3)degrees, gamma=13.628(3)degrees; V=930.0(3)angstrom(3), Z=2, D-cal=1.259Mgm(-3),mu=0.184mm(-1),lambda (MoKalpha)=0.71073 angstrom, final R1 and wR2 are 0.0470 and 0.1052, respectively. The piperidine rings adopt chair conformation. The planar phenyl rings are oriented equatorially at 2,6-positions of the piperidine ring. The molecular packing can be viewed as dimers held together by two N-H...S types of intermolecular hydrogen bonds. Weak C-H...pi interactions also support the stability of the molecules in the crystal in addition to van der Waals forces. (c) 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The reaction of Pd{kappa(2)(C,N)-C6H3Me-3-(NHC(NHAr)(=NAr))-2}(mu-Br)](2) (Ar = 2-MeC6H4; 1) with 4 equiv of PhC C-C(O)OMe in CH2Cl2 afforded Pd{kappa(2)(C,N)-C(Ph)=C(C(O)OMe)C(Ph)=C(C(O)-OMe)C6H3Me-3(N=C(NH Ar)(2))-2}Br] (Ar = 2-MeC6H4; 2) in 70% yield, and the aforementioned reaction carried out with 10 equiv of PhC C-C(O)OR (R = Me, and Et) afforded an admixture of two regioisomers of Pd{kappa(3)(N,C,O)-O=C(OR)-C5Ph3(C(O)OR)C(C(O)OR)C6H3Me-3(N=C(NHAr)( 2))- 2}Br] (Ar = 2-MeC6H4; R = Me (3a/3b), Et (4a/4b)) in 80 and 87% yields, respectively. In one attempt, the minor regioisomer, 4b, was isolated from the mixture in 6% yield by fractional crystallization. Palladacycles 3a/3b and 4a/4b, upon stirring in CH2Cl2/MeCN (1/1, v/v) mixture at ambient condition for S days, afforded Pd{eta(3)-allyl,(KN)-N-1)-C-5(C(O)OR)(2)Ph3C-(C(O)OR)C6H3Me-3(N=C(NH Ar)(2))(-2)}Br] (Ar = 2-MeC6H4; R = Me (5a/5b), Et (6a/6b)) in 94 and 93% yields, respectively. Palladacycles 3a/3b and 4a/4b, upon reaction with AgOTf in CH2CH2/Me2C(O) (1/1, v/v) mixture at ambient temperature for 15 min, afforded Pd{kappa(3)(N,C,O)-O=C(OR)C5Ph3(C(O)OR)C(C(O)OR)C6H3Me-3(N=C(NHAr)(2 ))-2}(OTf)] (Ar = 2-MeC6H4; R = Me (7a/7b), Et (8a/8b)) in 79 and 77% yields, respectively. Palladacycles 7a/7b and 8a/ 8b, upon reflux in PhC1 separately for 6 h, or palladacycles 5a/5b and 6a/6b, upon treatment with AgOTf in CH2Cl2/Me2C(O) (7/3, v/v) mixture for 15 min, afforded Pd{(eta(2)-Ph)C5Ph2(C(O)OR)kappa(2)(C,N)-C(C(O)OR)C6H3Me-3(N=C(NHAr) (2))-2}(OTf)] (Ar = 2-MeC6H4; R = Me (9a/9h), Et (10a/10b)) in >= 87% yields. Palladacycles 9a/9b, upon stirring in MeCN in the presence of excess NaOAc followed by crystallization of the reaction mixture in the same solvent, afforded Pd{kappa(3)(N,C,C)-(C6H4)C5Ph2(C(O)OMe)(2)C(C(O)OMe)(2)C6H3Me-3(N=C( NHAr)(2))-2}(NCMe)] (Ar = 2-MeC6H4; 11a/11b) in 82% yield. The new palladacycles were characterized by analytical, IR, and NMR (H-1 and C-13) spectroscopic techniques, and the molecular structures of 2, 3a, 4a, 4b, 5a, 6a, 7a, 9a, 10a, and 11a-d(3) were determined by single crystal X-ray diffraction. The frameworks in the aforementioned palladacycles, except that present in 2, are unprecedented. Plausible pathways for the formation of new palladacycles and the influence of the guanidine unit in 1, substituents in alkynes, reaction conditions, and electrophilicity of the bromide and the triflate upon the frameworks of the insertion products have been discussed.

Approaches toward (eta(2)-HX) (X = H, SiR (R = Me-3 or Me2Ph), CH3) sigma-complexes of ruthenium

Two new Ru(II)-complexes RuH(Tpms)(PPh3)(2)] 1 (Tpms - (C3H3N2)(3)CSO3, tris-(pyrazolyl) methane sulfonate) and Ru(OTf)(Tpms)(PPh3)(2)] 2 (OTf = CF3SO3) have been synthesized and characterized wherein Ru-H and Ru-OTf are the key reactive centers. Reaction of 1 with HOTf results in the Ru(eta(2)-H-2)(Tpms)(PPh3)(2)]OTf] complex 3, whereas reaction of 1 with Me3SiOTf affords the dihydrogen complex 3 and complex 1 through an unobserved sigma-silane intermediate. In addition, an attempt to characterize the sigma methane complex via reaction of complex 1 with CH3OTf yields complex 2 and free methane. On the other hand, reaction of Ru(OTf)(Tpms)(PPh3)(2)] 2 with H-2 and PhMe2SiH at low temperature resulted in sigma-H-2, 3 and a probable sigma-silane complexes, respectively. However, no sigma-methane complex was observed for the reaction of complex 2 with methane even at low temperature. (C) 2014 Elsevier B. V. All rights reserved.

Water temperature studies on the R. North Tyne after impoundment by Kielder dam. 3. Preliminary examination of water temperature data

The report describes the results of preliminary analyses of data obtained from a series of water temperature loggers sited at various distances (0.8 to 21.8 km) downstream of Kielder dam on the River North Tyne and in two natural tributaries. The report deals with three aspects of the water temperature records: An analysis of an operational aspect of the data sets for selected stations, a simple examination of the effects of impoundment upon water temperature at or close to the point of release, relative to natural river temperatures, and an examination of rate of change of monthly means of daily mean, maximum, minimum and range (maximum - minimum) with distance downstream of the point of release during 1983.

Cambios en las sinapsis del hipocampo de rata inducidos por el receptor de neurokinina 3 (NK3-R)

Mediante Western blot y cultivos celulares, en el presente trabajo se han observado las variaciones en el número de espinas dendríticas y sinapsis en neuronas del hipocampo de ratas macho de tres meses de edad, cuando se activa o se inhibe el receptor de neurokinina 3 (NK3-R) mediante drogas agonistas o antagonistas. Se ha visto que el gen de este receptor tiene una menor expresión en ratas muy ansiosas en comparación con las poco ansiosas, por lo que se pretende estudiar las implicaciones que pueda tener esta proteína en el trastorno de ansiedad.

M_2RSbO_6:R~(3+)复合氧化物的合成组成结构和性能的研究(M = Ba、Sr、Ca, R = La、Gd、Y、Bi, R' = Sm、Eu、Dy、Ho、Er、Tm)

对于稀土与非稀土所组成的二元复合氧化物的研究国外已有较多的报导。但是，对于稀土和锑的复合氧化物只是近年来才开始有些研究工作。含锑与稀土的多元复合氧化物的报导就更少。本文在我们实验室张静筠等人三元复合氧化物研究的基础上，开展Mo—Sb_2O_5—R_2O_3—R'_2O_3—Bi_2O_3多元体系的研究工作，这对于我国丰产元素稀土和锑的应用以及利用Bi~(3+)的激活与敏化将是有益的。本文按Thornton等人的方法合成了Ba_2BiSbO_6，Ba_2GdSbO_6，按EγΦECEHKO等人的方法合成了M_2RSbO_6 (M = Ba、Sr、Ca, R = La Y)。并以M_2RSbO_6为基质，掺Sm~(3+)、Eu~(3+)、Dy~(3+)、Ho~(3+)、Er~(3+)、Tm~(3+)和Bi~(3+)，研究它们的化学组成，晶体结构与发光性能的关系及规律，Bi~(3+)的荧光和敏作用。同时研究了它们的磁学和热学性能。化学组成的分析结果表明，计算的含量与实验测得的含量符合较好，说明化学反应是按化学计量比进行的。通过X-射线粉沫物相分析和晶胞参数的理论计算确定M_2RSbO_6(M = Ba、Sr、R = La、Y、Gd、Bi)复合氧化物是属于立方钙钛太型化合物。空间群为Fm3m，点群为Oh。用计算机计算了Ca_2YSbO_6的晶胞参数并结合荧光光谱分析确定它属于畸变的单斜钙钛矿，空间群为P_(21)。用磁天平测量了样品M_2RSbO_6 (M = Ba、Sr、Ca; R = Gd、Y、Bi)的磁化率。除Ba_2GdSbO_6是顺磁性物质外共余的都是反磁性的物质。按所用原料Sb_2O_5计算的磁化率与测量值符合较好，表明在所研究的M_2RSbO_6化合物中锑是正五价的。用热重热差分析仪测量了样品在反应中的热性能，观察到在化合物形成的过程中所用原料Sb_2O_3大约在520 ℃左右氧化变为Sb_2O_5。除所用原料碳酸盐分解外没有挥发性的物质，这就进一步证明化学组成分析和磁化率测量的结果是正确的。光学测量的结果表明，所有的磷光体随着激活离子浓度的不同其光谱都发生规律性的变化。对于不同Eu~(3+)浓度的Ba_2YSbO_6:Eu~(3+)和Br_2YSbO_6:Eu~(3+), Bi~(3+)体系用254nm激发时均能观察到Eu~(3+)于595nm的尖峰发射。用基质和Bi~(3+)的激发峰325nm激发时，明显地看到敏化剂Bi~(3+)到Eu~(3+)的能量传递，使Eu~(3+)于595nm的发射大大增强，我们认为Bi~(3+)对Eu~(3+)的敏化作用是由于基质和Bi~(3+)的~1S。→ 3P_1的跃迁吸收了激发的能量，然后无辐射弛豫到Eu~(3+)的激发态~5D_0，产生~5D_0 → 7F_1的磁偶极跃迁。对于不同Eu~(3+)浓度的Sr_2YSbO_6:Eu~(3+)和Sr_2YSbO_6:Eu~(3+), Bi~(3+)体系用245nm激发时均能观察到Eu~(3+)于595nm的尖峰发射。用基质和Bi~(3+)的激发峰335nm激发时，观察到基质和Bi~(3+)对Eu~(3+)具有某种能量传递。敏化作用机理与上述的Ba_2YSbO_6:Eu~(3+)和Ba_2YSbO_6:Eu~(3+), Bi~(3+)体系相同。对于不同Eu~(3+)浓度的Ca_2YSbO_6:Eu~(3+)和Ca_2YSbO_6:Eu~(3+), Bi~(3+)体系用396nm激发时，均能观察到Eu~(3+)于613nm很强的尖峰发射。用基质和Bi~(3+)的激发峰313nm激发时，见到Bi~(3+)和基质对Eu~(3+)具有某种能量传递，这种敏化作用主要是由于基质和Bi~(3+)的3P_1 → ~1S_0的400nm的宽带发射和Eu~(3+)的~7F_0 → ~5L_6的396nm的吸收相匹配产生~5L_6→~5D_0→~7F_2的跃迁。通过对激发光谱和荧光光谱的分析给出了Ca_2Y_(0.96)Eu_(0.04)SbO_6的能级图，从实验上可见，Eu~(3+)的发光强烈地依赖于钙钛矿的结构，当Eu~(3+)在空间群为Fm3m 的Ba_2YSbO_6和Sr_2YSbO_6中处于Oh点对称性时，主要是~5D_0 → ~7F_1的磁偶极跃迁。当Eu~(3+)在空间群为P_(21)的单斜钙钛矿中时，主要是~5D_0 → ~7F_2的电偶极跃迁。对于不同掺杂浓度M_2YSbO_6:R~(13+)(M = Ba、Ca; R' = Sm、Dy、Ho、Er、Tm)体系，通过激发和荧光光谱的研究，合理地确定了谱项。发现基质对Sm~(3+)、Dy~(3+)、Ho~(3+)具有敏化作用。对不同Bi~(3+)浓度的Ca_2YSbO_6:Bi~(3+)，由激发和荧光光谱可见Bi~(3+)具有二个激发带，第一激发带位于240nm处相当于~1S_0 → ~1P_1的跃迁，第二激发带位于315nm处相当于~1S_0 → ~3P_1的跃迁。有一个很强的兰紫色发射位于400nm处相当于~3P_1 →~1S_0的跃迁。
