This paper proposes and demonstrates the extraction of MOSFET threshold voltage, source-drain resistance, gate field mobility reduction factor, and transistor gain factor from the measurement of the small-signal source-drain conductance of a transistor as a function of dc gate bias with zero dc drain bias. The theory is based on the analytical model that includes the effects of source-drain res...

Several small emerging bipolar regions have been observed with the Advanced Stokes Polarimeter (ASP), including extensive time series measurements of one small region. Both new and previously recognized properties of the actual site of first emergence, where the magnetic field is nearly horizontal to the surface, are revealed by these observations. They provide the most complete and accurate ob...

BACKGROUND Perioperative blood loss is still an unsolved problem in total knee arthroplasty (TKA). The efficacy of the preoperative use of tranexamic acid (TXA) plus drain-clamping to reduce blood loss in TKA has been debated. This meta-analysis aimed to illustrate the efficacy of TXA plus drain-clamping to reduce blood loss in patients who underwent a TKA. METHODS In February 2017, a systema...

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...
