Where There Is a Will,There Is a Way

<正>"Where there is a will,there is a way."It is my motto.I believe I can succeed as long as I work hard.Actually,I didn’t feel confident before,because I had many shortcomings and I didn’t want to make efforts.This made me often screw up a lot of things.At that time I didn’t know how to change myself,so I asked my father about this.He told me,"Where there is a will,there is a way."It means I should make more efforts than before.     

Evaluation of a permeability–porosity relationship in a low-permeability creeping material using a single transient test

A method is presented for the evaluation of the permeability–porosity relationship in a low-permeability porous material using the results of a single transient test. This method accounts for both elastic and non-elastic deformations of the sample during the test, and is applied to a hardened class G oil well cement paste. An initial hydrostatic undrained loading is applied to the sample. The generated excess pore pressure is then released at one end of the sample while monitoring the pore pressure at the other end and the radial strain in the middle of the sample during the dissipation of the pore pressure. These measurements are back-analysed to evaluate the permeability and its evolution with porosity change. The effect of creep of the sample during the test on the measured pore pressure and volume change is taken into account in the analysis. This approach permits to calibrate a power law permeability–porosity relationship for the tested hardened cement paste. The porosity sensitivity exponent of the power–law is evaluated equal to 11, and is shown to be mostly independent of the stress level and of the creep strains.

a21办公住宅

<正>"每天清晨,我想做的第一件事就是能以一种舒适和快乐的心情开始我的设计工作。我曾经梦想的办公住宅并不应该是设在像胡志明市这样一个交通阻塞频繁和高度污染的城市,而这个小面积、非方正的小房子不仅符合设计预算,而且所处位置远离闹市且仅十分钟就可以抵达市中心。其条件非常符合我选择它作为新办公地点的最佳选地。"设计师Toan说到。

luther's thesenportal: a case study of a “ritual-architectural event”

ABSTRACT

This article is part of a larger field-based study of contemporary festivity and religious tourism in Lutherland, a geographic and symbolic place associated with the life and work of Martin Luther. My aim, with reference to the work of Lindsay Jones and Victor Turner, is to develop an approach for studying the intersection of material culture and ritual. Material culture does not simply signify into empty space, shining meanings into its surrounding environment as a street lamp does light. Rather, material culture is produced, handled, used in a variety of ways. An exemplary case for studying how built space and ritual performance intersect is the Thesenportal of Wittenberg's Schlosskirche, an object and performative space commemorating the origin of the German Reformation.

Static tests on a soil–steel bridge structure with a relieving slab

The paper deals with a new, arch road bridge made from structural corrugated plates, over the Plawna Stream, on a local road between Bystrzyca Klodzka and Ladek Zdroj in Stary Waliszow, Poland. The bridge replaced the old stone arch bridge that was destroyed during the flood of 1997. The steel bridge is founded on two continuous footings made of reinforced concrete. Its effective span is 10.00 m and its clear height is 4.02 m. The results of tests carried out on the bridge under three static load schemes after four years of service are presented. The average values of the measured displacements and strains in selected points and elements of the steel shell structure were found to be considerably lower than the ones calculated for the same load. Since designs of this type are more and more often adopted for small- and medium-size bridges, the conclusions drawn from the presented tests can be generalised to the whole class of such bridge structures.     

Is crime in Mexico a disamenity? Evidence from a hedonic valuation approach

Since Roback’s seminal work (J Polit Econ 90(6):1257–1278, 1982), the literature on hedonic prices has evaluated the role of amenities in equilibrating regional differentials in nominal wages and prices. While these studies generally find evidence for traditional amenities and disamenities in developed countries, there remains little research on how characteristics such as violence affect the equilibrium in less developed countries. This article explores violence and other local characteristics as an amenity or disamenity for Mexico and employs the hedonic wage and rent theory proposed by Roback. This research uses a multilevel estimation technique using data from the Mexican Household Income and Expenditure Survey, along with other information from the municipal and state levels. This article finds evidence to suggest that illegal earning opportunities outweigh crime disamenity by inhabitants of some traditional drug-trafficking regions, because such crime appears to be the modus vivendi in those regions in a way that does not reduce economic performance.     

Is fluoridation a fraud?

During the past 15 years tooth decay rates have declined markedly amongst children in many parts of the industrialised world. Over the same period, however, decay rates have increased dramatically in children in developing countries. For many years it has been claimed that water fluoridation is the most important and cost-effective method for controlling dental caries. A series of recent papers in the scientific literature have challenged the 'fluoridation hypothesis', since the decline in decay reported in the developed countries has occurred in both fluoridated and unfluoridated areas. In some countries of the developing world, tooth decay is now reaching crisis proportions, hence it is important to know whether fluoridation really can "reduce tooth decay by about 60 per cent", or if the dental profession has been promoting a 'flawed' hypothesis for more than 40 years.

通过调控载脂蛋白(a)基因表达降低脂蛋白(a)血浆水平

<正>脂蛋白(a)是1963年由Berg等[1]从血浆中分离出来的一种与低密度脂蛋白(low density lipoprotein,LDL)相似的蛋白质。与LDL相比,脂蛋白(a)具有更强的氧化活性及致炎作用,因此其致动脉粥样硬化(As)的能力更强[2-3]。这与其分子组成密切相关。脂蛋白(a)是由载脂蛋白B100[apolipoprotein B100,apo B100]和富含神经氨酸的糖蛋白apo(a)[apolipoprotein(a),apo(a)]通过二硫键共价结合而成[1,4]。脂蛋白(a)的致病作用主要源于其脂

Biological removal of 17α-ethinylestradiol by a nitrifier enrichment culture in a membrane bioreactor

Increasing concern about the fate of 17α-ethinylestradiol (EE2) in the environment stimulates the search for alternative methods for wastewater treatment plant (WWTP) effluent polishing. The aim of this study was to establish an innovative and effective biological removal technique for EE2 by means of a nitrifier enrichment culture (NEC) applied in a membrane bioreactor (MBR). In batch incubation tests, the microbial consortium was able to remove EE2 from both a synthetic minimal medium and WWTP effluent. A maximum EE2 removal rate of 9.0 μg EE2 g⁻¹ biomass-VSS h⁻¹ was achieved (>94% removal efficiency). Incubation of the heterotrophic bacteria isolated from the NEC did not result in a significant EE2 removal, indicating the importance of nitrification as driving force in the mechanism. Application of the NEC in a MBR to treat a synthetic influent with an EE2 concentration of 83 ng EE2 L⁻¹ resulted in a removal efficiency of 99% (loading rates up to 208 ng EE2 L⁻¹ d⁻¹; membrane flux rate: 6.9 L m⁻² h⁻¹). Simultaneously, complete nitrification was achieved at an optimal ammonium influent concentration of 1.0 mg NH₄⁺-N L⁻¹. This minimal NH₄⁺-N input is very advantageous for effluent polishing since the concomitant effluent nitrate concentrations will be low as well and it offers opportunities for the nitrifying MBR as a promising add-on technology for WWTP effluent polishing.
