Biocementation treatment consists in using bacteria or other biological agents to promote the precipitation of calcium carbonate (biocement) soil pores. When used slopes for protection against surface erosion, this creates a stiff and strong pervious cover, allowing infiltration necessary reduce water runoff. The knowledge retention properties biocemented soils is fundamental modelling but it m...

Tillage practices can influence the pore size distribution (PSD) of soil, affecting soil physical and hydraulic properties as well processes that are essential for plant growth, hydrology, environmental studies modeling. A study was conducted to assess effect no-tillage (NT) conventional tillage (CT) on PSD derived from soil–water retention curves (SWRCs) using van Genuchten’s equation (vG) at ...

In this study, the aim was to compare experimental and empirical methods used for estimation soil water retention under different conditions. Soil samples were chosen represent examples of heavy, medium light structures. Water curves obtained in laboratory using standard method. The van Genuchten (1980) (vG), Brooks Corey (1964) (BC) empirically. Model parameters determined by artificial neural...

The majority of hydraulic processes under a natural condition in a field are carried out under unsaturated flow conditions. The soil moisture retention curve (SMRC) is the most important hydraulic characteristic of an unsaturated soil whose knowledge is of prime importance in soil-water studies such as soil conservation, soil erosion, land evaluation, soil reclamation, and water resources manag...

OBJECTIVE To evaluate the risk factors for postoperative urinary retention in women who underwent vaginal hysterectomy for symptomatic pelvic organ prolapse. METHODS The medical records of 221 women who underwent vaginal hysterectomy with anterior and posterior colporrhapy were reviewed. Urinary retention after catheter removal was defined as the presence of at least one of the following thre...

STUDY OBJECTIVE To assess the effects of tiotropium on lung mucociliary clearance in COPD. DESIGN Randomized, double-blind, placebo-controlled, parallel-group study. SETTING Outpatients of an urban-area university teaching hospital. PATIENTS Thirty-four patients with COPD aged 40 to 75 years classified equally into two groups. INTERVENTION Single (18 microg) daily dose of tiotropium inh...
