Soil moisture distribution shows highly variation both spatially and temporally. This study assesses the spatial heterogeneity of soil moisture on a hill-slope scale in the Loess Plateau in West China by using a geostatistical approach. Soil moisture was measured by time-domain reflectometry(TDR) in 313 samples. Two kinds of sampling scales were used(2 x 2 m and 20 x 20 m) at two soil layers(0-30 cm and 30-60 cm). The general characteristics of soil moisture were analyzed by a classical statistics method,and the spatial heterogeneity of soil moisture was analyzed using a geostatistical approach. The results showed that the spherical model is the best-fit model to simulate soil moisture on the experimental hill-slope. The parameters of this model indicated that the spatial dependence of soil moisture in the selected hill-slope was moderate. Even the 2 x 2 m sampling scale was too coarse to show the detailed spatial variances of soil moisture in this area. The dependent distance increased from 27.4 m to 494.16 m as the sampling scale became coarse(from 2 x 2 m to 20 x 20 m). A map of soil moisture was generated by using original soil moisture data and interpolated values determined by the Kriging method. The average soil moisture(area weighted) in the different layers of soil was calculated on the basis of this map(10.94% for the 0-30 cm soil layer,11.88% for the 30-60 cm soil layer). This average soil moisture is lower than the corresponding average effective soil moisture,which suggests that the soil moisture is not sufficient to support vegetation in this area.

ACL reconstruction surgery shows low incidence of complications (1.38%) like DVT, Infection, patellar tendon rupture and fractures whether in the proximal tibia or the distal femur. We hereby present two cases that have had the rare complication of proximal tibial fracture. The circumstances of each case are discussed together with discussion of similar cases described in the literature. We tried in the end to have an idea about the possible causes and how to prevent such a devastating event. Case presentation: Case 1 shows a 38-year-old female patient who had an ACL reconstruction surgery by BTB graft followed by iatrogenic proximal tibial fracture managed by open reduction internal fixation by T plate and screws. Case 2 shows a 28-year-old male patient who had an ACL reconstruction surgery by BTB graft also followed by Proximal tibial fracture 3 weeks later managed by open reduction internal fixation using a locked plate and screws. Discussion: Fractures are a rare complication that may follow ACL reconstruction surgery. These fractures can be femoral or tibial that may be due to the reduction of the bone strength as a result of the drill holes which behave as a stress riser. We also suggest that usage of osteotomes during grafting plays a role in these fractures. management of these fractures is either by open reduction and internal fixation or closed reduction. What is known about the subject: Patellar fractures are a known complication of ACL reconstruction using patellar tendon graft. What this study adds to the existing knowledge: Raising the Knowledge that also the tibia can be fractured as a complication of patellar tendon harvesting not only the patella.

＜正＞Ship waves in shallow water are greatly different from those in deep water. In the present paper, the numerical method of ship waves by Tanimoto et al. was applied to open sea with a constant water depth and a coast with straight, parallel depth contours in order to investigate characteristics of propagation and transformation of ship waves. The ship length is 82m, the breadth is 14.6m and the draft is 5.88m. The ship sails on a straight course of a constant water depth from 6.5m to 18m. The wave pattern changes by the depth Froude number as pointed out by Havelock. When the ship speed is critical or super-critical, bow waves ahead of the ship are split to several isolated waves as they propagate. Transformations due to shoaling and refraction occur when ship waves propagate on the sloping coast. When the ship sails on the straight course of 15m deep and the speed is critical, the maximum wave height exceeds to 2m at the water depth of 1.5m.

＜正＞the need for detection of turn fault at primary stages, such that maintenance can be planned ahead, has pushed the development of monitoring method with increasing sensitivity and noise immunity. An important issue in such effort is the modeling of induction motor under turn fault conditions with minimum computation and complexity and maximum accuracy. magnetic equivalent circuit is em ployed in the simulation and analysis of squirrel cage induction motor with turn to turn fault and unbalance magnetic pull that is arisen from this fault. Simulation and experimental results are presented to support the proposed approach.

OBJECTIVE: The aim of this study was to investigate the messenger ribonucleic acid expression of leptin (L-mRNA) and the leptin receptor (OB-RmRNA) in subcutaneous fat tissue and to determine their relationship with leptin and testosterone and steroid serum levels over the course of the menstrual cycle (mC), in obese (OBW) and non-obese women (NOW). DESIGN: Observational study investigating mRNA transcript expression of leptin and the leptin receptor from human subcutaneous fat specimens, as well as leptin serum levels, both in relation to the testosterone and sex hormones during the mC in obese and non-obese women. mETHODS: Nineteen women, thirteen with a body mass index (BmI) > 25 Kg/m2 and 6 with BmI 2 were included. RT-PCR was used to detect L-mRNA transcripts of leptin and its receptor in samples from 28 fat biopsies taken from seven volunteers (20 from OW and 8 from NOW). The serum concentrations of leptin and steroid hormones were measured throughout the mC using radioinmuno analysis. RESULTS: The percentages of women expressing leptin L-mRNA during the phases of the mC were: early follicular (EF), 14.3%;late follicular (LF), 28.6%;early luteal (EL), 14.3%;and late luteal (ll), 42.9%. The percentages of OB-RmRNA were: EF, 71.4%;LF, 14.3%;EL, 28.6%;and ll, 71.4%. Leptin serum levels were directly related to BmI (p mRNA expression and its receptor in subcutaneous human tissue are regulated throughout the mC in a periodic manner. The physiological role of testosterone in regulation of expression L-mRNA and OB-RmRNA during the secretory phase of the mC in obese women requires further investigation.
