Analysis of the Variation of Unconfined Ground-Water Level Due to the Change of Water Level in a Surface Reservoir

In this paper, an analytical method is proposed for calculating the variation of unconfined ground-water level in steady state due to the change of water level in a lake or a river and presents some examples which deal with the variation of ground-water level in the southeast alluvial plain of Lake Biwa. In most alluvial plains, the compositions of the strata are so complicated that the depth, the permeability and the ground-water flow can not be surveyed continuously. Then even if some pumping tests and some observations of ground-water level are carried out, it is very difficult or almost impossible to comprehend the behaviors and to calculate the variation accurately by means of a normal treatment. Authors propose to adopt the conception “quasi-depth” which means the permeable capacity into this analytical method. Only the “quasi-depth” is variable and the other elements can be treated as constant factors in analyzing the variation of ground-water level numerically and graphically. The most advantageous point for using the “quasi-depth” in this method is that it is not necessary to measure the depth and the permeability continuously except for the depth at any selected point along a longitudinal section

Therapeutic effect of hyperthermia combined with chemotherapy on vulvar and vaginal carcinoma.

A clinical trial was performed to investigate the efficacy of hyperthermia in combination with chemotherapy for gynecological malignancies. Sixty-nine patients with vaginal or vulvar malignancies (9 primary vulvar, 3 recurrent vulvar, 11 primary vaginal, 4 primary cervical, 40 recurrent cervical, and 2 recurrent ovarian carcinomas) were treated by thermochemotherapy (42 cases) or chemotherapy alone (27 cases). After treatment, 7 patients underwent surgery and 46 patients irradiation. The chemotherapeutic schedule was mainly a combination therapy with bleomycin and mitomycin C (B-M). Microwaves of 2.45 GHz were applied to induce local hyperthermia. The side effects of chemotherapy were not increased by hyperthermia. The rate of partial response plus complete response increased to 84% (16/19) in primary cancers and 45% in recurrent cancers by hyperthermia, compared to the respective values of 40% (2/5) and 17% (3/17) for chemotherapy alone. However, a satisfactory prognosis cannot be expected with thermochemotherapy, unless additional treatments are performed. Subsequent surgery or radiation treatment improved the progression-free interval.</p

Advection Dispersion by Eulerian Lagrangian Finite Element Method

In this paper the author will be describe phenomena of advection dispersion in subsurface flow by using Eulerian Lagrangian Finite Element Method. Where Finite Element Method with Galerkin formulation and weigthed residual method is used to solve seepage and advection dispersion equation. The problem of one dimensional and two dimensional rectangular wave are analyzed in this paper. And the result of numerical analyses will be compared with analytical solutions. The numerical results showed the very good agreement with the analytical solutions

In situ determination of field-saturated hydraulic conductivity of subsurface soil of vadose zone by technique of Pressure Infiltrometer

For reducing or bridging gap between small scale laboratory investigations and large scale field investigations, a simple and portable model which is based on real situation and has a compatibility to laboratory core sampling, the pressure infiltrometer technique is introduced for determination of field-saturated hydraulic conductivity. The field -saturated hydraulic conductivity, K(FS), is obtained from measurements of steady flow rates applying constant head as well as falling head principle. The device is also used for field core sampling on which laboratory constant head as well as falling head tests is carried out. The field device is validated through comparison to laboratory core sample experiment and other existing methods. This paper describes first time a versatile field device representing good performance for in situ determination of hydraulic parameters in a short time

Dynamical properties of S=1 bond-alternating Heisenberg chains at finite temperatures

Dynamical structure factors of the S=1 bond-alternating spin chains in the dimer phase are calculated at finite temperature, using the pair dynamical correlated-effective-field approximation. At T=0, the delta-function-type peak of the one-magnon mode appears. When temperature is increased, such a sharp peak is broadened and the additional weak peak caused by the excitation from the triplet state to the quintet state emerges in the higher energy region. The results are discussed in comparison with those obtained by the exact diagonalization method.Comment: 5 pages, 4 figure
