H IGH-SPEED collisionless, or free-molecular, gas flows passing through small circular or annular holes are fundamental problems with many real applications such as neutral gas expansion out of electric propulsion (EP) devices. Usually, the cold plume flow out of an EP device is modeled by assuming freemolecular flows with a nonzero uniform average exit velocity U0. Even when the average bulk v...

We introduce the concept of the network architect to extend theory explaining how brokers create and manage structural holes in mediated markets. We argue that a broker’s social resources and dependence on the market, along with exogenous deal conditions, influence the broker’s motivations and willingness to make tradeoffs between long-term and short-term considerations when constructing deal n...

conclusions: pe may be developed as late as weeks after cardiac surgeries. pe after palliative cardiac surgeries is not uncommon. low doses of aspirin and corticosteroids are usually effective for treating this complication. objectives: our aim was to assess the prevalence, risk factors, time course and therapy response of pericardial effusion (pe) after cardiac surgeries in children. patients ...

malignant pleural effusion is a common complication in certain malignancies. pleurodesis is the best option most of the time. the purpose of this study was to compare the choice of belomycin with povidone-iodine, which is not only determined by the efficacy of the agent but also by its cost, accessibility, safety, ease of administration and the number of administrations to achieve a complete re...

background: patients with symptomatic malignant pleural effusion (mpe) may gain profit from pleurodesis for relief of dyspnea and in preventing the accumulation of fluid or air in the pleural space. pleurodesis methods are palliative and regard the patient's symptoms and underlying disease condition that are different. the purpose of this study was to assess the efficacy of bleomycin in th...

Background: Otitis media with effusion is one of the leading causes of hearing loss in children. Effective treatment of effusion in the middle ear requires appropriate empirical treatment and characterization of responsible pathogens. Objective of the present study was to detect pathogens in clinical samples from patients with otitis media with effusion in our area and to determine the sensitiv...

Tuberculosis (TB) is one of the oldest and commonest infectious diseases also known as “master of Death”. Pulmonary TB (PTB) and TB with pleural effusion remains a diagnostic challenge. Adenosine deaminase (ADA) is an enzyme of purine catabolism which is an inexpensive and easy test in early routine evaluation of patients with pleural effusion. Aim: To assess the diagnostic level of ADA in TB p...

While pleural effusion and ascites secondary to acute pancreatitis are common, clinically relevant pericardial effusion and cardiac tamponade are observed rarely. In a study by Pezzilli et al., pleural effusion was noted in 7 of the 21 patients with acute pancreatitis whereas the authors detected pericardial effusion development in only three. The authors asserted that pleural effusion was asso...

celiac disease is an autoimmune disorder that affected 1% of all population in united state. classic manifestations ofdisease consist of early childhood diarrhea, malabsorption, steatorrhea and growth retardation but disease can affects adult at any age. in adult anemia is a more frequent finding. this patient was a 40-year-old lady with progressive fatigue and lower extremities pitting edema. ...
