We have compared the effect of peritonsillar infiltration with tenoxicam 5 mg and placebo on postoperative pain after tonsillectomy. Fifty patients undergoing bilateral elective tonsillectomy under general anaesthesia were allocated randomly to receive peritonsillar infiltration with tenoxicam 5 mg in 8 ml of normal saline (4 ml per tonsil) or normal saline only, before tracheal extubation. Med...

We investigated the safety of LIA (local infiltration analgesia) combined with retransfusion of drained blood. Total knee arthroplasty patients received two peri-articular injections during surgery followed by continuous infusion, both with ropivacaine (567 mg). Ropivacaine plasma concentrations were determined in blood samples taken at 0, 3, 6 and 24 hours postoperatively. The collected shed b...

Recently, a novel approach with excellent performance based on the concept of characteristic infiltration time, time method (CTM), is proposed to infer soil sorptivity (S) and saturated hydraulic conductivity (Ks) from one-dimensional (1D) cumulative infiltration. The current work provides simplified version CTM, called SCTM, by eliminating necessity iteration used in CTM providing similar accu...

Abstract Infiltration plays a fundamental role in streamflow, groundwater recharge, subsurface flow, and surface water quality quantity. This study includes comparative analysis of the two machine learning techniques, M5P model tree (M5P) Gene Expression Programming (GEP), predictions infiltration characteristics. The models were trained tested using 7 combination (CMB1 – CMB7) input parameters...

A wetting soil water characteristic curve (SWCC w ) is necessary for understanding and interpreting the re-distribution of infiltrated rainwater, percolation rate, contaminant transport. Direct determination SWCC tedious needs destructive sampling invasive sensor installation. This study demonstrates an indirect method determining based on infiltration measurements using a mini disc infiltromet...

The water infiltration rules of five different homogeneously or heterogeneously-constructed soil samples were determined to select the best construction module for refuse dump reclamation in opencast mines Shanxi-Shaanxi-Inner Mongolia energy circle. Five treatments, including three homogeneous consisting sandy soil, Montmorillonite-enriched sandstone, and sand-Montmorillonite-enriched sandston...

Accurate inversion of soil hydraulic parameters based on the van Genuchten–Mualem model has received much attention in science research. Herein, a hybrid algorithm method using particle swarm optimization and vector-evaluated genetic was used to invert θs, α, n, Ks, with objective functions infiltration rate, cumulative infiltration, water content. Then, numerical experiments were conducted fou...

objectives:the aim of the present study was to assess the analgesic efficacy of iv ketamine injection inaddition to nephrostomy tract infiltration of ketamine – bupivacaine on postoperative pain relief after tubeless percutaneous nephrolithotomy (pcnl). patients and methods: patients (n = 100), with renal stone who were candidates for pcnl were randomized to five groups with 20 cases in each: g...

Background & objective Changes in submucosal vascularization and inflammation, determined by immunohistochemistry staining, were shown to be correlated with the development of dysplasia and invasiveness of epithelial cells in premalignant and malignant lesions. This study evaluated changes in sections routinely stained with Hematoxylin and Eosin (H&E) in order to investigate vascular density an...

To reveal the mechanisms of water conservation and soil salinity control in biochar interlayer, effects addition as an interlayer on infiltration, evaporation, salt transport were studied. Through indoor soil-column simulation test, columns set up by packing homogeneous (CK) spacers into at different burial depths 10, 20, 30 cm. The decreased infiltration capacity soil, with average rate decrea...
