Arteriovenous fistula Definition An arteriovenous fistula AV fistula is the connection of a vein and an artery, usually in the forearm, to allow access to the vascular system for hemodialysis, a procedure that performs the functions of the kidneys in people whose kidneys have failed. Connecting the vein and artery is a surgical procedure. The fistula develops over a period of months after the surgery. Purpose The surgical creation of an AV fistula provides a long-lasting site through which blood can be removed and returned during hemodialysis. The fistula, which allows the person to be connected to a dialysis machine, must be prepared by a surgeon weeks or months before dialysis is started. When the vein and artery are joined, the vein gradually becomes larger and stronger, creating the fistula that provides vascular access years longer than other types of access and with fewer complications. Sometimes dialysis is only needed temporarily, but some people need it for the rest of their lives or until a kidney is available for a transplant.

Component at the surface of a well that provides the structural and pressure-containing interface For water well wellheads, see Puteal. A wellhead is the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment. Wellhead gas storage, Etzel Germany Oil well Christmas tree The primary purpose of a wellhead is to provide the suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment.
If the pressure is not contained during drilling operations by the column of drilling fluid , casings, wellhead, and BOP, a well blowout could occur. When the well has been drilled, it is completed to provide an interface with the reservoir rock and a tubular conduit for the well fluids. The surface pressure control is provided by a Christmas tree , which is installed on top of the wellhead, with isolation valves and choke equipment to control the flow of well fluids during production.
Deaths in the month following gastric bypass surgery are very rare (about % to %, or less than one in people) when the procedure is done by a highly experienced surgeon.
Before trying to hook up your player, make sure it is plugged in and turns on when you press the “power” button. Usually a small light or welcome message appears when the DVD player is working correctly. There are at three common ways to connect a DVD player, and each needs a different cable to work. Your DVD player should come with all of the appropriate cords, but you need to check which connections your TV accepts as well.
The three most common are. HDMI connections are the highest quality connections and you only need one cord for both the audio and video.

The structure contains the return value from the window procedure that processed the message, as well as the message parameters associated with the message. Subclassing the window does not work for messages set between processes. The value the hook procedure returns determines whether the system allows or prevents one of these operations. For more information, see the CBTProc callback function.
Pick up the string to have a hook load equal to the weight, in air, of the pipe above the selected back-off point, plus 10 to 15%. Apply left hand torque in a series of steps. Work the pipe at each step to transfer the torque downhole.
A maintenance inspection b. A safety and operational inspection The maintenance inspection is geared more to preventative maintenance and identifying those items requiring repairs that will prevent the crane from being in a like new condition or from operating correctly, such as oxidized or cracking paint, sheet metal damage, track pad wear, track roller wear, rubber tire wear, oil levels, oil changes, etc. The Equipment Superintendent or his representative usually performs this inspection.
The safety and operational inspection, on the other hand is more concerned with identifying those items that will either stop a lift during the middle of an operation such as a worn sheave bearing that could freezes to it’s shaft or those items that could possibly lead to a component failure and an accident such as a hoist line with broken wires or a bent boom lacing. For example, this inspection would not be as concerned with tire wear because all lifts are required to take place on outriggers.
However, excessive tire wear would be noted on the inspection report. Both inspections can be and sometimes are done by the same inspection party, but this procedure is geared to the safety and operational inspection and assumes that someone else will complete the maintenance inspection. Cranes should be visually inspected by “a qualified person”. A qualified person being someone who by virtue of his education and experience is knowledgeable about cranes, crane maintenance and rigging operations.
Cranes should be inspected per the crane manufactures recommendations and rigging procedures. This means that the crane must be assembled with components specified by the manufacture and using his assembly procedures. Cranes should be visually inspected per good rigging practices and Industry standards. Listed below are the most important items to inspect on a conventional crawler or truck crane and some wear tolerances: Boom suspension line and end attachment devices.

An efficient in vitro propagation method for Caralluma edulis was developed. Abstract Caralluma edulis Edgew. Poor reproduction and seed set have put adverse pressure on native populations of this endemic and slow multiplying plant of Indian Thar Desert. Though it is categorized as endangered plant species, there is need for revision of its status as this species can be spotted rarely in its habitat. There is also need for development of non-conventional methods for propagation and conservation of C.
Therefore, in vitro methods are good alternative for multiplication, propagation and germplasm conservation of this nutraceutically important plant.
A wellhead is the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment.

Our photo shows an owner who has lifted the loose, poorly-sealed well piping and cap right off of the steel well casing. This well needed repairs and it needed to be sterilized using the well chlorination procedure we discuss here. Therefore it is vital that the well be constructed so that no new contamination may enter the well following completion of the shock disinfection. In order to achieve a satisfactory disinfection of the system, the bacteria must be brought in contact with a chlorine solution of sufficient strength and remain in contact with that solution for a sufficient time to achieve a complete kill of all bacteria and other microorganisms.
Details of the Well Chlorination Procedure – Exactly How to Shock a Well, Where to Put Chlorine, How Much Chlorine to Use to Shock the Well If drinking water has been tested and has not passed standards for safe drinking, or any time the building water supply system has been opened for repairs such as replacing a submersible well pump or a jet pump foot valve , the well should be disinfected following these procedures, and should be re-tested as described below.

HG and MC collected the data and they were the major contributor to the manuscript; MK and DS contributed to the operative treatment of the shoulder; TAS contributed to the treatment of the spinal cord injury and the shoulder. This article has been cited by other articles in PMC. Abstract In case of patients with spinal cord injury and concomitant acromioclavicular AC joint-dislocation the treatment is challenging, as in this special patient group the function of the shoulder joint is critical because patients depend on the upper limb for mobilization and wheelchair-locomotion.
Therefore the goal of this study was to examine, if the treatment of chronic AC-joint dislocation using the Weaver-Dunn procedure augmented with a hook-plate in patients with a spinal cord injury makes early postoperative wheelchair mobilization and the wheelchair transfer with full weight-bearing possible. In this case the Weaver-Dunn procedure with an additive hook-plate was performed in a year-old male patient with a complete paraplegia and a posttraumatic chronic AC-joint dislocation.
