The one-stage electrohydrodynamic (EHD) pumps with electrodes “a diaphragm – a plate hole” and wire are studied. It is established that the help of flow-limiting diaphragms, pump characteristics can be significantly improved. indicated in main multi-stage EHD pumps, it preferable to use lattice-type made bare perforated insulated wires. Optimal geometrical parameters electrodes, dielectric coat...

abstract: the new neonatal ventilation methods have been developed along with utilization of new technological tools.this device is synchronized with the patient’s respiratory efforts. the ideal synchronized breath needs to be synchronous with initiation, size, and termination of the breath without delay in detecting of initial resiratory effort by device .the synchrony of respiration contribut...

Diaphragmatic hernias are usually congenital, and they usually occur in the neonatal group. They do occur in the adult population, albeit very rarely. We present a case of an adult male patient with complications as a result of a congenital diaphragmatic hernia. The patient presented with atypical abdominal pain and respiratory distress. Radiological investigations confirmed a left hydropneumot...

A model of squeeze-film behavior is developed based on Stokes' equations for viscous, compressible isothermal flows. The flow domain is an axisymmetrical, unit cell approximation of a planar, periodic, perforated microstructure. The model is developed for cases when the lubrication approximation cannot be applied. The complex force generated by vibrations of the diaphragm driving the flow has t...

Acute death from caustic ingestion is uncommon. We report an autopsy case of acute fatality from suicidal ingestion of a liquid caustic soda solution with peritoneal leakage due to a stab wound to the stomach. The victim was a 58-year-old man, who died about 1 h after being transported to a hospital emergency care unit. There were corrosive erosions around the mouth and a stab wound in the lowe...

In this paper, using theory of sheets, the deflection of suspended diaphragm has been obtained under uniform and circular loading. This type of diaphragm, unlike other diaphragms, has a central support which is recommended to be used in MEMS applications. The relationship between diaphragm deflection and static analysis of this diaphragm enjoys a great significance in investigating and understa...

Background: Aim: Peptic perforation is one of the commonest surgical emergencies met with but due to poor socioeconomic status, lack of health consciousness and want of diagnostic & treatment facilities at the peripheral healthcare level, they present considerably late most of the time. Our aim was to study the factors affecting prognosis. Methods: A prospective review was made in all charts of...

Gastric adenocarcinoma is a rare entity in the pediatric population. Gastric hepatoid adenocarcinoma with elevated serum alpha-fetoprotein (AFP) is seen extremely rarely in children. A 12-year-old boy was admitted to the hospital with complaint of abdominal pain. X-ray revealed free air density below the diaphragm. Emergent laparotomy showed perforated stomach. Four weeks after the operation, h...

The patient was an emergency transported, 57-year-old man complaining of left thoraco-lateroabdominal pain, with a history of blunt chest trauma 3 months prior. Thoracoabdominal computed tomography (CT) resulted in a diagnosis of diaphragmatic hernia with incarceration and perforation of the stomach, and same-day emergency surgery was performed. The surgery was performed via an abdominal approa...

A 58-year-old man presented to the Emergency Department with a two-day history of vomiting, diarrhea and intermittent central abdominal pain. His background history was significant for peptic ulcer disease. On examination there was diffuse abdominal tenderness, and a fecal occult blood test was positive. A departmental chest radiograph had appearances suggestive of a pneumoperitoneum, with an e...
