43 A is an important water management practice in the midwestern United States to remove excess water from poorly drained areas and to provide traffi cable conditions for agricultural production. About 30% of the total land area and 50% of the crop land in Indiana is subsurface drained (Economic Research Service, 1987). Th ere are growing concerns about the potential negative environmental impa...

sive, be easy to apply and remove, ensure the security of the drain and maximize patient comfort. These goals are achievable, but often drain security is prioritized at the expense of patient comfort and practicality. We have found an effective method for dressing sutured drains with the use of a single “All-In-One” dressing or a 20 × 10-cm adhesive-absorbent pad (Primipore; Smith & Nephew, St....

In this experimental trial , 133 patients with single long bone fracture requiring surgery, admitted in Shahid Mohammadi Hospital (Bandar Abbas/Iran) from June 2002 to April 2003, were randomly devided into two groups. In the first group (72 individuals), after the completion of the operation a single hemovac drain was inserted, while in the second group (61 patients) no drain was used. The two...

Background: CSF leak during or after transsphenoidal surgery is the most common annoying complication that may lead to fatal meningitis. Objective: To define the effectiveness of the external CSF lumbar drain to stop the leak either inserted preoperative, immediate postoperative or delayed postoperative with the same figure of packing to the sella turcica and sphenoid sinus. Methods: We retrosp...

While there has been growing interest in two-dimensional (2-D) crystals other than graphene, evaluating their potential usefulness for electronic applications is still in its infancy due to the lack of a complete picture of their performance potential. The focus of this article is on contacts. We demonstrate that through a proper understanding and design of source/drain contacts and the right c...

Fixing a surgical tube-drain is a common procedure (usually delegated to the junior-most trainees) that can significantly alter the postoperative morbidity. Ironically, in spite of today's technological advances in the surgical field, drain-related complications are still being reported. However, its inadequate fixation is largely responsible for a significant, though, preventable morbidity (li...

Chest draining is a common procedure for treating pleural effusion. Perforation of the heart is a rare often fatal complication of chest drain insertion. We report a case of a 76-year-old female patient suffering from congestive heart failure. At presentation, unilateral opacity of the left chest observed on a chest X-ray was interpreted as massive pleural effusion, so an attempt was made to dr...

The effect of gate length on the operation of silicon-on-insulator (SOI) MOSFET structure with a layer of buried silicon oxide added to isolate the device body has been simulated. Three transistors with gate lengths of 100, 200 and 500 nm are simulated. Simulations show that with a fixed channel length, when the gate length is increased, the output drain current characteristics slope is increas...

One of the most important factors for appropriate performance of subsurface drainage systems is having adequate discharge for drains. For this purpose, knowledge about effect of drainage parameters change on drain discharge is essential in subsurface drainage systems. In this article, using change all of the drainage parameters by EnDrain software, changes of drains discharge has been investiga...

A 70-year-old man had undergone pancreaticoduodenectomy due to a distal common bile duct malignancy. After the operation, serous fluid discharge decreased from two drain tubes in the retroperitoneum. Over four weeks, the appearance of the serous fluid changed to a greenish bile color and the patient persistently drained over 300 ml/day. Viewed as bile leak at the choledochojejunostomy, treatmen...
