analyses illustrated that the spatial structure estimate obtained from measurement scale SLIla was inconsistent with that obtained from measurement scale t+. Thus, we conclude that the infiltrometer instrument fundamentally alters the infiltration process in such a way that measurements are only meaningful in a relative sense. Steady-state infiltration rates were measured at three instrument sc...

bioretention or rain garden is a preferable low impact development (lid) approach due to its characteristics which reflect natural water cycle processes. however, this system is still little understood and quite complicated in terms of design and implementation due to many technical considerations. hence, this paper gives a review of the challenges and developments for the use of bioretention f...

BACKGROUND Fatty infiltration of the liver is associated with an increased morbidity and mortality in children with severe protein-energy malnutrition (PEM), but its pathogenesis remains unclear. Although impaired synthesis of VLDL apolipoprotein B-100 (VLDL-apo B-100) is generally accepted as the pathogenetic mechanism, the rate of it synthesis has not been measured in children with PEM. OBJ...

The shortage of water resources makes it urgent to increase agricultural irrigation efficiency. In response this need, study develops a real-time adaptive control (RACI) system for border irrigation. Avoiding the need traditional systems calculate soil infiltration properties in real-time, RACI adjusts inflow rate based on difference between actual and expected advance time. Simulations collect...

OBJECTIVES Chest computed tomography (CT) scanning has been widely utilized in thymoma identification and staging as well as in follow-up monitoring for recurrence. However, the relationship between some CT imaging features and pathological types, clinical stage, completeness of resection, or prognosis in thymoma has not been well explored. METHODS We retrospectively reviewed preoperative CT ...

A field experiment was conducted to study the effect of deficit irrigation and mulch levels on soil physical properties and growth and yield of maize crop. The experiment comprised of two irrigation levels, i.e. I1: 558.8 mm and I2: 711.2 mm while two mulch levels, i.e. M0: no mulch and M15: 15 Mg ha. Soil samples were collected from 0-10, 10-20, and 20-30 cm depths before sowing and at crop ha...

Measuring infiltration at the plot scale is difficult, especially for high hydraulic conductivity soils. At the plot scale, the infiltration rate is usually calculated by comparing surface runoff to rainfall. Direct measurement of infiltration beyond the point scale is typically limited to locations where land forming (e.g., infiltration pond) has been performed or fields with basin irrigation ...

BACKGROUND Most patients with hepatocellular carcinoma (HCC) have advanced-stage disease at diagnosis. The prognosis for patients with HCC is very poor, especially for those with portal vein tumour thrombi (PVTT). The purpose of our study was to observe the prognostic value of PVTT and tumour-infiltrating regulatory T cells (Tregs) and the correlation between them. METHODS We examined 76 HCC ...

The purpose of this study was to determine the effect land preparation methods on soil infiltration which can be used as a basis for designing irrigation dryland rice cultivation. arranged in completely randomized design (CRD) with three treatments, namely T0 (no tillage), T1 (hoeing), and T2 (hoeing plus loosening). Each treatment carried out replication plots. Artificial rain given an average...

infiltration is a complex process that changed by initial moisture and water head on the soil surface. the main objective of this study was to estimate the coefficients of infiltration equations, kostiakov-lewis, philip and horton, and evaluate the sensitivity of these equations and their coefficients under various initial conditions (initial moisture soil) and boundary (water head on soil surf...
