Marine clay soils are problematic in the construction industry when they subjected to loads. When these loaded, lose their structure. This leads soil being unable withstand loads of any magnitude without exhibiting significant, permanent deformations. In order stabilize marine soil, new methods for improvement were built upon biogrouting by incorporating physical, biological and chemical treatm...

Two-phase oil and gas flow were simulated in an entirely eccentric annulus compared with experimental data at horizontal, 4, 10, 90° inclination. The gas-phase was sulphur hexafluoride the liquid phase a mixture of Exxsol D60 Marcol 82 for inclined cases (5–16), pure horizontal (1–4). diameter outer inner cylinders 0.1 0.04 m, respectively, domains 0.05 m domain. studied consist fractions betwe...

Employees involved in various occupational environments that include vibration machines and any kind of vehicles are adversely subjected to multiple source noise. Thus, the corresponding noise frequencies (and mainly infrasound ones) present high interest, especially from viewpoint sustainability, due potential effects on human safety health (H_S&H) sustainable engineering projects. Moreove...

This paper characterizes the optimal labor market policy within a dynamic search model of the labor market which allows for workers’ risk aversion. In a …rst-best allocation of resources, unemployment bene…ts should provide perfect insurance against the unemployment risk, layo¤ taxes are necessary to induce employers to internalize the cost of dismissing an employee but should not be too high i...

Economic Approaches to Understanding Change in Happiness Are people condemned to an inherent level of experienced happiness? A review of the economic research on subjective well-being gives reason to the assessment that happiness can change. First, empirical findings clearly indicate that people are not indifferent to adverse living conditions when reporting their subjective well-being as obser...

We introduce delay in simultaneous-move mechanisms. Delay is infinitesimal in equilibrium, hence the name: imminent implementation. We show that mechanisms with delay implement rules that are not implementable without delay in Nash equilibrium and its refinements. We obtain a version of the monotonicity condition that is necessary and sufficient for imminent implementability. If the domain incl...

Multiple-epoch, multicolor images of the astrometric binary Gliese 105A and its very low mass companion Gliese 105C have been obtained using the Hubble Space TelescopeÏs Wide Field Planetary Camera 2 (WFPC2) and near-infrared camera and multiobject spectrometer (NICMOS). The optical and near-infrared colors of Gl 105C strongly suggest a spectral type of M7 V for that star. Relative astrometric ...
