Most multicellular organisms can be categorised by two words： hierarchy and composite. The underlying f.actal geometry of.nature - at least in terms of.provision of.inf.astructure - provides much of.the hierarchy, although many materials f.r which inf.astructure is not an integral f.ctor are also strongly hierarchical. Plants can theref.re be modelled using recursive computer programs which add structures as the size increases. However, problems with mechanical stability also increase as the structure grows, so the plant changes f.om deriving stif.ness f.om intevaal pressure to cross-linking the cell wall components permanently. However, this compromises the ability of.the plant to grow and repair itself.

The applicatio n of.nano particles as selective drug delivery platf.rms arises as one the most promising therapeutic strategies in the biomedical f.eld. Such systems can encapsulate drugs, prevent its premature degradation, transport and promote the drugs specif.c delivery to the target site. Among the dif.erent nanostructures, gold-core mesoporous silica shell (AuMSS) nanorods have been one of.the most explored due to their unique physical and chemical properties. The mesoporous silica biocompatibility, high surf.ce area that can be easily f.nctionalized, tubular pores that can store the drugs, conjugated with the intrinsic capacity of.gold nanorod to absorb near-inf.ared radiation, allows the combination of.hyperthermia (i.e., photothermal ef.ect) with drug delivery, making them a nanoplatf.rms with a huge potential f.r cancer therapy. Nevertheless, the successf.l applicati on of.AuMSS nanoparticles as an ef.ective can cer nano medicine is hindered by the uncon trolled release of.the therapeutic payloads, limited blood circulation time and unf.vorable pharmacokinetics. In this review, an overview of.the modif.cati ons perf.rmed to improve the AuMSS nano rods applicati on in nanom edicine is provided, highlighting the practical approaches that enhaneed the AuMSS nanorods targeting, responsiveness to dif.erent stimuli, and blood circulation time. f.rther, the basics of.AuMSS nano rods syn thesis procedures, gen eral properties, and its applicati on in can cer therapy are also described.

A body moving near the f.ee surf.ce is a f.cus in f.uid dynamic research. Many numerical methods were developed f.r the simulation of.the induced f.ow f.eld. In this paper, a two-dimensional square moving near the f.ee surf.ce was simulated by the volume of.f.uid method (VOf.. The f.ow f.eld and drag exerted on the square were studied. The drag would increase due to the presence of.the f.ee surf.ce. The iteration f.ctor of.the pressure interpolation of.surf.ce cells was modif.ed, and through this modif.cation the iteration became more stable. The capability of.dealing with the large def.rmation of.the f.ee surf.ce was raised.

Polyvinylidene f.uoride （PVDf. hollow f.ber membranes prepared f.om spinning solutions with dif.erent polyvinyl pyrrolidone （PVP） contents （1% and 5%） at dif.erent extrusion rates were obtained by wet/dry phase process keeping all other spinning parameters constant. In spinning these PVDf.hollow f.bers, dimethylacetamide （DMAc） and PVP were used as a solvent and an additive, respectively. water was used as the inner coagulant. Dimethylf.rmamide （DMf. and water （30/70） were used as the external coagulant. The perf.rmances of.membranes were characterized in terms of.water f.ux, solute rejection f.r the wet membranes. The structure and morphology of.PVDf.hollow f.ber were examined by BET adsorption, dry/wet weight method and scanning electron microscopy （SEM）. It is f.und that the increase in PVP content and extrusion rate of.spinning solution can result in the increase of.water f.ux and decrease of.solute rejection. The improvements of.interconnected porous structure and pore size are induced by shear-thinning behavior of.spinning solution at high extrusion rates, which could result in the increase of.water f.ux of.hollow f.ber membranes. The increase of.extrusion rate also leads to the increase of.membrane thickness due to the recovery ef.ect of.elastic property of.polymer chains.

While wormholes are as good a prediction of.Einstein’s theory as black holes, they are subject to severe restrictions f.om quantum f.eld theory. In particular, holding a wormhole open requires a violation of.the null energy condition, calling f.r the existence of.exotic matter. The Casimir ef.ect has shown that this physical requirement can be met on a small scale, thereby solving a key conceptual problem. The Casimir ef.ect does not, however, guarantee that the small-scale violation is suf.icient f.r supporting a macroscopic wormhole. The purpose of.this paper is to connect the Casimir ef.ect to noncommutative geometry, which also aims to accommodate small-scale ef.ects, the dif.erence being that these can now be viewed as intrinsic properties of.spacetime. As a result, the noncommutative ef.ects can be implemented by modif.ing only the energy momentum tensor in the Einstein f.eld equations, while leaving the Einstein tensor unchanged. The wormhole can theref.re be macroscopic in spite of.the small Casimir ef.ect.

This paper presents results of.ground-experimental study on the start-up characteristics of.a Loop Heat Pipe. The physical process of.start-up is described, and the explanation that “Pressure Transf.r” leads to the saturated temperature rise in compensation chamber during start-up is f.rst discussed. Start-up behaviors as a f.nction of.various parameters including vapor/liquid distribution in the evaporator, adverse elevation, start-up heat load, sink temperature are described and explained. A peculiar start-up phenomenon composed of.two start-up scenarios was f.rst observed at adverse elevations and is described.
