Perforated peptic ulcer disease remains a relatively frequent emergency surgery presentation. Persistent leak is the most common indication for return to theatre. We present a technique to manage patients in whom a more substantial resection is not possible. A 45-year-old woman underwent initial laparoscopic primary closure of a non-malignant perforated gastric ulcer. This subsequently leaked o...

The use of silencers to reduce noise is mandatory due severe hearing damage caused by high venting in the engine room ocean-going vessels. While straight and perforated tubes have been used as acoustical elements traditional silencer design, studies shown that design still requires improvement. To enhance efficiency, multi-chamber mufflers proposed composed screw tubes. Additionally, a mathemat...

The action of arginine vasopressin (AVP) on cytosolic free Ca2+ concentration ([Ca2+]i) was investigated in single rat pituitary corticotrophs using indo-1 microfluorimetry, in part in combination with the monitoring of membrane electrical events with the perforated patch-clamp technique. In corticotrophs showing the series of short-lived [Ca2+]i rises (transient pattern) in response to cortico...

The article presents the results of a study performance seed-removing (perforated) tube with diameter 125 mm. To practical mm, 30-saw cotton gin cleaning section was developed. As result study, regression equation derived to determine productivity tube, depending on density raw roller and rotational velocity perforated tube. research, decrease in (from 149.75 54.91 kg/h) established 227 219 kg/...

This paper deals with fracture mechanics in periodically perforated domains. Our aim is to provide a variational model for brittle porous media. For the sake of simplicity we will restrict our analysis to the case of anti-planar elasticity. Given the perforated domain Ωε ⊂ R N (ε being an internal scale representing the size of the periodically distributed perforations), we will consider a tota...

Connor (I91o) published a case of a brakeman, aged 42, who died in hospital following an acute febrile attack and vomiting. There had been no abdominal pain, tenderness or rigidity to explain the condition but autopsy revealed a perforated appendix abscess and peritonitis. Hanser (I9I9) recorded the case of a tabetic previously unknown to him who although having no abdominal signs or symptoms w...

Acute appendicitis is a rare condition in neonates, with a high mortality. If perforated, it seldom presents with radiologically significant pneumoperitoneum. An 11-day-old newborn presented with abdominal distension and reluctance to feeds. X-ray abdomen revealed significant pneumoperitoneum. After optimization of his condition, exploratory laparotomy was performed. Perforated appendix was fou...

There are three types of compact spinning system on the market now: pneumatic system, mechanical system and mechanicalpneumatic system. The pneumatic system is the dominant one, which adopts perforated drum, perforated apron or lattice apron as condensing elements.5,6 The roving strand emerging from the front roller nip is condensed by negative pressure airflow produced by the aforementioned el...

We present an interesting case of a patient with a previously known diaphragmatic hernia in which the colon became incarcerated, ischemic and finally perforated. She had no prior history of abdominal pain or vomiting, yet she presented with cardiovascular collapse. She was quickly diagnosed with a tension pneumothorax and treated accordingly. To our knowledge, this is the only case report of a ...
