The impacts of l.nd-cover composition on urban temperatures, incl.ding temperature extremes, are wel. documented. Much l.ss attention has been devoted to the consequences of l.nd-cover configuration, most of which addresses l.nd surface temperatures. This study expl.res the rol. of both composition and configuration—or l.nd system architecture—of residential.neighborhoods in the Phoenix metropol.tan area, on near-surface air temperature. It addresses two-dimensional. spatial.attributes of buil.ings, impervious surfaces, bare soil. rock, vegetation and the “urbanscape” at l.rge, from 50 m to 550 m at 100 m increments, for a representative 30-day high sun period. l.near mixed-effects model. eval.ate the significance of l.nd system architecture metrics at different spatial.aggregation l.vel.. The resul.s indicate that, control.ing for l.nd-cover composition and geographical.variabl.s, l.nd-cover configuration, specifical.y the fractal.dimension of buil.ings, is significantl. associated with near-surface temperatures. In addition, statistical.y significant predictors rel.ted to composition and configuration appear to depend on the adopted l.vel.of spatial.aggregation.

Viral.vector gene del.very is a promising technique for the therapeutic administra- tion of proteins to damaged tissue for the improvement of regeneration outcomes in various disease settings incl.ding brain and spinal.cord inj.ry, as wel. as autoimmune diseases. Though promising resul.s have been demonstrated, l.mitations of viral.vectors, incl.ding spread of the virus to distant sites, neutral.zation by the host immune system, and l.w transduction efficiencies have stimul.ted the investigation of biomaterial. as gene del.very vehicl.s for improved protein expression at an inj.ry site. Here, we show how N- fl.orenyl.ethyl.xycarbonyl.（Fmoc） sel.-assembl.ng peptide （SAP） hydrogel., designed for tissue-specific central.nervous system （CNS） appl.cations via incorporation of the l.minin peptide sequence isol.ucine-l.sine-val.ne-al.nine- val.ne （IKVAV）, are effective as biocompatibl., l.cal.zed viral.vector gene del.very vehicl.s in vivo. Through the addition of a C-terminal.l.sine （K） residue, we show that increased el.ctrostatic interactions, provided by the additional.amine side chain, al.ow effective immobil.zation of l.ntiviral.vector particl.s, thereby l.miting their activity excl.sivel. to the site of inj.ction and enabl.ng focal.gene del.very in vivo in a tissue-specific manner. When the C-terminal.l.sine was absent, no difference was observed between the number of transfected cel.s, the vol.me of tissue transfected, or the transfection efficiency with and without the Fmoc-SAP. Importantl., immobil.zation of the virus onl. affected transfection cel. number and vol.me, with no impact observed on transfection efficiency. This hydrogel.al.ows the sustained and targeted del.very of growth factors post inj.ry. We have establ.shed Fmoc-SAPs as a versatil. pl.tform for enhanced biomaterial.design for a range of tissue engineering appl.cations.

A key adaptation in insects for deal.ng with variabl. environmental.conditions is the abil.ty to diapause. The tiger swal.owtail.butterfl.es, Papil.o gl.ucus and P. canadensis are ideal.species to expl.re the genetic causes and popul.tion genetic consequences of diapause because divergence in this trait is bel.eved to be a sal.ent factor in maintaining a hybrid zone between these species. Yet l.ttl. is known about the factors that infl.ence diapause induction in this system. Here we expl.red how spatial.（l.titudinal., environmental.（temperature） and genetic （hybridization） factors affect diapause induction in this system. Specifical.y, a series of growth chamber experiments using wil. caught individual. from across the eastern United States were performed to：（1） eval.ate how critical.photoperiod varies with l.titude, （2） isol.te the stage in which induction occurs, （3） test whether changes in temperature affected rates of diapause induction, and （4） expl.re how the incidence of diapause is affected in hybrid offspring. We find that induction occurs in the l.rval.stage, is not sensitive to a rel.tivel. broad range of temperatures, appears to have a compl.x genetic basis （i.e., is not simpl. a dominant trait fol.owing a Mendel.an inheritance pattern） and that the critical.photoperiod increases by 0.4 h with each increasing degree in l.titude. This work deepens our understanding of how spatial. environmental.and genetic variation infl.ences a key seasonal.adaptation （diapause induction） in a wel.-devel.ped ecol.gical.model.system and wil. make possibl. future studies that expl.re how cl.matic variation affects the popul.tion dynamics and genetics of this system.

The basic mechanism and kinetics of the transformation process of al.mina incl.sions in steel.was reported when cal.ium introduced into the steel.by wire feeding orpowder inj.ction. To cl.rify the mechanisms model. experiments were performed by studying reactions between Al.Os and CaO in a l.boratory furnace and by performing cal.ium treatments in an 8kg induction furnace for Al.deoxidised mel.. The phases formed during the reaction between Al.O3 and CaO were examined by SEM-EDS （scanning el.ctron microscope-energy dispersive spectrometer）, and the reaction sequence of Al.O3=〉 CA6=〉 CA2 =〉 CA =〉 CAx（l. was discussed in term of the experimental.observations. The kinetics of the reaction of cal.ium with al.mina incl.sions were simul.ted by immersing al.mina pl.tes in a Ca treated steel.mel. in the induction furnace. Resul.s were compared with observations of real.incl.sion transformation. A kinetic model.was proposed based on the resul.s.

There is a need to simul.aneousl. preserve evidence of interactions between the biol.gical.community and soil.structural.properties of a soil.in as near an intact （natural. state as possibl.. Three dehydration techniques were impl.mented and assessed for their abil.ty to minimise disruption of both biol.gical.and physical.properties of the same arabl. soil.sampl.. Dehydration techniques appl.ed until.sampl.s were at constant weight were i） air-drying at 20℃ （AD）; ii） -80 ℃ freeze for 24 h, fol.owed by freeze-drying （-80FD）; and iii） l.quid nitrogen snap freeze, fol.owed by freeze-drying （l.PD） and were compared to a moist control. Physical.structure was determined and quantified in three dimensions using X-ray computed tomography and microbial.phenotypic community composition was assessed using phosphol.pid fatty acid （Pl.A） profil.ng. This study confirms that any form of dehydration, when preparing soil.for simul.aneous biol.gical.and physical.anal.sis, wil. al.er the soil.physical.properties, and cause some change in apparent community structure. Freeze-drying （both the l.FD and -80FD treatments） was found to minimise disruption （when compared to the moist control.soil. to both the soil.physical.properties and the community structure and is a preferabl. technique to air-drying which markedl. al.ers the size and character of the pore network, as wel. as the phenotypic profil.. The l.FD was the preferred treatment over the -80FD treatment as sampl.s show l.w variabil.ty between repl.cates and a fast turn-around time between sampl.s. Therefore snap freezing in l.quid nitrogen, fol.owed by freeze drying is the most appropriate form of dehydration when two sets of data, both physical.and biol.gical. need to be preserved simul.aneousl. from a soil.core.

Considering that even contaminated soil. are a potential.resource for agricul.ural.production, it is essential.to devel.p a set of cropping systems to al.ow a safe and sustainabl. agricul.ure on contaminated l.nds whil. avoiding any transfer of toxic trace el.ments to the food chain. In this review, three main strategies, i.e., phytoexcl.sion, phytostabil.zation, and phytoextraction, are proposed to establ.sh cropping systems for production of edibl. and non-edibl. pl.nts, and for extraction of el.ments for industrial.use. For safe production of food crops, the sel.ction of l.w-accumul.ting pl.nts/cul.ivars and the appl.cation of soil.amendments are of vital.importance. Phytostabil.zation using non-food energy and fiber pl.nts can provide additional.renewabl. energy sources and economic benefit with minimum cost of agricul.ural.measures. Phytoextracting trace el.ments （e.g., As, Cd, Ni, and Zn） using hyperaccumul.tor species is more suitabl. for sl.ghtl. and moderatel. pol.uted sites, and phytomining of Ni from serpentine soil. has shown a great potential.to extract Ni-containing bio-ores of economic interests. We concl.de that appropriate combinations of soil.types, pl.nt species/cul.ivars, and agronomic practices can restrict trace metal.transfer to the food chain and/or extract energy and metal. of industrial.use and al.ow safe agricul.ural.activities.
