BACKGROUND Chest tube removal is a painful procedure. The goal of this study was to evaluate the effect of cold application in combination with Indomethacin suppository on chest tube removal pain in patients undergoing open heart surgery. MATERIALS AND METHODS This single-blind, double-group clinical trial was performed on 66 patients aged 18-68 years with the chest tube in pleural space. The...

With the growing need for more energy, it is imperative to design efficient heat exchangers that are simpler, cheaper manufacture, have higher transfer rates, and low in pressure drop. One of these double tube exchanger used many industries. From past present, caught attention researchers because their simplicity wide range applications. This review paper contains a critical analysis impact dif...

During insertion of the double lumen tube in patients with cervical vertebral fixation, the cervical neutral position should be maintained. Although flexible fiberoptic bronchoscopic intubation is the gold standard, novel techniques are needed to facilitate intubation of patients with cervical vertebral fixation in neutral position according to institutional capabilities. In this case report, i...

.Hot metal gas forming of tubes can be used in various industries such as automotive and aerospace industries. In this process tube is formed at elevated temperatures, by using gas instead of fluid pressure. Lower required pressure and low power are its advantages in comparison to hydroforming process. In this paper, a hot metal gas bulging process of an aluminum alloy tube has been investigate...

Double-lumen tubes have proved to be a useful adjunct in thoracic surgery. Their use has become quite commonplace, particularly since the introduction of the softer polyvinylchloride (PVC) tubes, which are technically easier to use and may carry less risk for serious complications. Any such tube, however, can cause life-threatening complications. We present a case with such a complication relat...

The pollen tube of flowering plants undertakes a long journey to transport two sperm cells for double fertilization. New work on pollen tube guidance has identified an arabinogalactan-derived ovular factor that primes tubes to respond to female gametophyte-secreted attraction signals.

Members of the Eph receptor tyrosine kinase have previously been implicated in cranial neural tube development. Failure of neural tube closure leads to the devastating conditions known as anencephaly and spina bifida. EphA2 and EphA4 are expressed at the tips of the closing spinal neural folds prior and during neural tube closure. We investigated the possible role of murine EphA2 and EphA4 duri...

In this paper, using energy method, small scale effects on the buckling analysis of a double-walled carbon nanotube (DWCNT) under external radial pressure is studied. The constitutive equations derived for a DWCNT using the nonlocal theory of elasticity which Eringen are presented for the first time. By minimizing the second variation of the total energy for a DWCNT, hence, the value of the non...

A preterm newborn required pulmonary surfactant administration and high frequency oscillatory ventilation due to respiratory distress syndrome. VACTERL association was suspected after diagnosis of several congenital anomalies (butterfly vertebra, double left ureteral system, double outlet right ventricle and limbs anomalies). A nasogastric tube was passed and tip position was confirmed in the s...
