Epoxy has been widely used as a coating material to protect the steel reinforcement in concrete structures, because of its outstanding processability, excellent chemical resistance, good electrical insulating properties, and strong adhesion/affinity. The major disadvantage raised from exothermic curing reaction highly crosslinked epoxy matrix is brittleness microcracks that change performances....

We build a workable game of common-property resource extraction under rational Bayesian learning about the renewal prospects of a resource. We uncover the impact of exogenously shifting the prior beliefs of each player on the response functions of others. What we …nd about the role of environmental conservation campaigns is paradoxical. To the extent that such campaigns instill overly high pess...

The issue of nonanalytic corrections to the Fermi-liquid behavior is revisited. Previous studies have indicated that the corrections to the Fermi-liquid forms of the specific heat and the static spin susceptibility (C}T , xs 5const) are nonanalytic in D<3 and scale as dC(T)}T, xs(T)}T , and xs(Q)}Q , with extra logarithms in D53 and 1. It is shown that these nonanalytic corrections originate fr...

Even in patients with clinically stable asthma with normal lung function, the airways are characterized by inflammatory changes, including mucosal swelling. In order to investigate whether lung sounds can distinguish these subjects from normal subjects, we compared lung sound characteristics between eight normal and nine symptom-free subjects with mild asthma. All subjects underwent simultaneou...

Intrinsic fluorescence of LDH-C4 has been studied in the presence of optical isomers of gossypol. The study showed that fluorescence due to tryptophan residues after excitation of LDH at 282 nm is quenched by each gossypol enantiomere in a concentration dependent manner. Half of the maximum quench (Q50%) of enzyme occurred with gossypol (-) at 0.9 x 10(-4) mol/l and with gossypol (+) at 1.4 x 1...

The objectives of this study are: 1) to capture the existing condition river channel in Sangatta River estuary, including bathymetry bed, and cross-sectional dimensions river, 2) design a stable navigation estuary that allows less maintenance dredging improves navigability during critical when water level is at lowest, 3) test effectiveness cross section term availability navigable depth. This ...

Abstract Baseflow is a very important component in maintaining river flow. generated from groundwater role water conservation. Indonesia located tropical climate. Based on the Koppen climate classification, included rainforest (type Af), so that characteristics of climate, soil, flora and fauna are unique. About 70% Indonesia’s territory consists water. island region has unique characteristic. ...

Edgeworth’s taxation paradox states that an excise tax can decrease the market price of a good. This paper presents a new version of the paradox in which a tax reduces price because it attracts entry of additional …rms into the market. The paper also presents two new applications: (i) an emissions tax that leads to an increase in industry emissions (due to entry), and (ii) an interest rate cut ...

We study decisions in a dynamic game where firms’ private production leads to accumulation of a public bad, for example in the form of pollution. Firms have an option to invest in clean technology, which lowers emissions, or contributions to the public bad. The main treatment variable is access to clean technology, or benefits from such investment, which can be private or common. In the private...

We investigate the role of anonymity, reciprocity, and conformity for voluntary contributions, based on a natural field experiment conducted at a national park in Costa Rica. Contributions made in public in front of the solicitor are 25% higher than contributions made in private. Giving subjects a small gift before requesting a contribution increases the likelihood of a positive contribution. A...
