In this paper the analytical solutions for radial consolidation that include time dependent surcharge loading and vacuum pressure are proposed, whilst also considering the impact of the parabolic variation of permeability in the smear zone. The use of the spectral method for multilayered soil consolidation is introduced and verified. The Elliptical Cavity Expansion Theory is used to predict the...

Background:Despite numerous reports that it is not necessary to use drains after thyroidectomy, the drains are still used routinely. The study aim to compare thyroid surgery complications with and without drains appliance. Materials and methods: A prospective study was conducted, 66 patients who were candidate for thyroid surgery (totalsubtotal thyroidectomy and thyroid lobectomy) divided into ...

BACKGROUND The aim of gynecomastia surgery is to restore a normal chest contour with minimal signs of breast surgery. OBJECTIVE The authors examine the rate of complications in gynecomastia surgery when no closed-suction drains are placed. METHODS One hundred thirty-eight consecutive male patients who underwent gynecomastia surgery without drains were retrospectively analyzed to determine w...

A settlement analysis has been carried out for several sectors of a rail station yard improved with prefabricated vertical drains (PVD) in Istanbul, Turkey, that exhibited prolonged consolidation beyond the predicted values certain treated zone. Final and End Primary (EOP) times have estimated theoretically as well using Asaoka graphical procedure. The compliance settlement-time curves in-situ ...

Macropore flow results in the rapid movement of pesticides to subsurface drains, which may be caused in part by a small portion of macropores directly connected to drains. However, current models fail to account for this direct connection. This research investigated the interrelationship between macropore flow and subsurface drainage on conservative solute and pesticide transport using the Root...

BACKGROUND Abdominal drains have been placed prophylactically and removed in liver resection without robust evidence. The present study was designed to establish the optimal time for removal of such drains. METHODS Data on abdominal prophylactic drains were analysed in a consecutive series of patients who underwent liver resection for malignancy between 2006 and 2009. Bilirubin levels in drai...

PURPOSE OF REVIEW Small-bore chest tubes are widely used in the management of common pleural disease. Guidelines suggest that patients with malignant pleural effusions, pneumothorax and pleural infection may be successfully managed with small-bore drains. However, good quality data is often lacking. This article reviews the evidence for the treatment efficacy and potential adverse effects of di...
