Some mathematical expressions for the basicity or XPS chemical shift, such as charge parameter and optical basicity, are compared with experimental O1s binding energy in binary alkali oxide glasses. The expressions so far in use need some modification in parameters. A new empirical expression introduced in this paper gives new concept and universal scale of basicity.

This article discusses dynamics of the automobile industry, one of the highest growth manufacturing sectors under the liberalization policy in the 1990s. After a brief historical explanation of the industry, the author describes corporate strategies of new comers, classified into three divisions; i.e. passenger car, commercial vehicle and two wheelers. Then he also analyze their distribution patterns from the view point of transport cost and Indian industrial location policy. The location of car assembly units in the 1990s tends to concentrate in greenfields on the outskirts of the existing agglomerations of the automobile industry.

Suction-controlled simple shear tests were carried out for the unsaturated sand. Drained tests for the saturated sand were also carried out for the comparison with the unsaturated sand. The increase of the shear strength of the sand with the matric suction is very small and there is almost no increase of that over 20 kPa of the matric suction. The suppression effect of the matric suction on the volume change bahavior during shear is small, and the degree of dilation increases with the increase of the matric suction.

Meteorological and soil moisture environments inside a greenhouse are significantly different from those in the open field. These differences should be understandable to establish accurate predictions of water consumption and evapotranspiraton inside a greenhouse which play impotrant roles in the design of any irrigation system. This study aims to estimate the micrometeorological conditions inside a watermelon plastic greenhouse which can be used for evapotranspiration calculations. Therefore, micrometeorological data were measured inside and outside the greenhouse for the comparison purposes. The results of this study may be summarized as : (1) Solar radiation inside the greenhouse was about 70% of that of outside it. (2) Net radiation during the daytime inside the greenhouse was almost the same as the absorbed total short-wave radiation. (3) The difference of air temperature inside and outside the greenhouse was very large during the daytime whereas not much difference was observed during the nighttime. (4) Both relative humidity and saturation deficit inside the greenhouse were higher than outside in case of highly vegetative land. (5) Wind speed inside the greenhouse was almost zero, while outside the average value was 1.8m/s. No potential conflict of interest relevant to this article was reported.

The sensitive degree of water shortage area in the irrigation project are classified by those models. They are solved by simplex method. Firstly, the Two-phase method is applied to analyze the artificial variables in the formulated model. Then, the formulated model is modified after getting rid of the artificial variables to obtain the feasible solution. The agricultural planning is planned by considering the classified area with social equity and economic improvement. Crop diversification is introduced to conduct in the very sensitive water shortage area and intermittent irrigation system is introduced to operate in the moderately sensitive water shortage area. The integrated farming system, the separation of land owner and cultivator and the disposition of substitute lots system are also suggested to conduct in this study project.

The data consist of two parts corresponding to the time-periods: 1973-93 and 1900-72. The study area is one of most affected places by the annual monsoon hydrological cycle and the present observation from these temperature data indicate that the surface air temperature gradient in the north-south direction is significant in the rainy season and that the temperature of the region is at an increasing tendency; the warming rate during the data periods (1900-93) on the long-term mean annual basis is estimated as 0.77℃ at Satkhira of the Khulna division and 0.29℃ as an areal average including the Barisal division, for the time difference of about half a century between the data periods before and after 1972.

The aim of the analysis was: (1) to observe a true distribution pattern of the wave-induced pore-pressure oscillations acting on the pipeline outer surface, and (2) to verify small-scale test results using numerical computations performed for a wide range of saturation conditions of seabed sediments, under the assumption of a compressible two-phase medium compound of the pore-fluid and soil skeleton, as well as a finite thickness of a permeable seabed layer.

However, the distribution of cases of severe mental retardation suggests a threshold in the low dose region. Data are composed of a binary (1,0) for mentally retarded or normal individuals. The statistical approaches with a threshold are conceivable for a simple, odds, logistic and Gompertz regression models. Estimation of threshold and 100(1-α)% confidence limits are derived from the maximum likelihood technique based on a profile approach.

We see that the upwind-type finite element method is effective in both cases, when the diffusion constant is quite small. No potential conflict of interest relevant to this article was reported.
