In this thesis, I study the time-varying behavior of a ventilated thermocline with basin scales at annual and decadal time scales. The variability is forced by three external forcings: the wind stress (chapter 3), the surface heat flux (chapter 4) and the upwelling along the eastern boundary (chapter 5). It is found that the thermocline variability is forced mainly by wind in a shadow zone whil...

Secretion management in the mechanically ventilated patient includes routine methods for maintaining mucociliary function, as well as techniques for secretion removal. Humidification, mobilization of the patient, and airway suctioning are all routine procedures for managing secretions in the ventilated patient. Early ambulation of the post-surgical patient and routine turning of the ventilated ...

During one-lung ventilation (OLV) in the lateral position, the dependent, ventilated lung receives more blood flow than the non-dependent, non-ventilated lung owing to gravity, improving the match of ventilation and perfusion. Conversely, in the rare clinical situations when OLV is applied to the non-dependent lung, arterial oxygenation can get worse due to considerable shunt flow to the depend...

To investigate the role of cell-mediated immunity during respiratory syncytial virus (RSV) infection, interferon (IFN)-gamma and interleukin (IL)-10 levels in nasopharyngeal secretions were measured in infants with lower respiratory tract infection (LRTI) caused by RSV. A novel technique was used to measure in vivo cytokine levels in nasopharyngeal aspirates (NPAs). Cytokine levels in the NPAs ...

Previously ventilated preterms are at a high risk of abnormal visual and neurological development when compared to full term babies non-ventilated preterms. Preterm birth is associated with retinopathy prematurity can also affect the brain structures post-retinal processing information. These impairments continue into adolescence adulthood may contribute difficulties in learning, attention, beh...

UNLABELLED Guillain-Barre Syndrome (GBS) has an unpredictable clinical course with up to 30% of patients requiring assisted ventilation during the course of their illness. Successful management mandates anticipation, prompt recognition and optimal treatment of neuromuscular respiratory failure in GBS. AIMS To identify clinical and electrodiagnostic predictors of neuromuscular respiratory para...

aim : the aim of this study is to estimate oral cavity cancer mortality for iranian population, using bayesian approach in order to revise this misclassification. background : mortality is a familiar projection to address the burden of cancers, but according to iranian death registry, about 20% death statistics were still recorded in misclassified categories. patients and methods : we analyzed ...

background: assessment of uterine abnormalities is a core part in infertility evaluation. objective: the aim of this study was to evaluate the sensitivity and specificity of three-dimensional hysterosonography (3-dhs) in the diagnosis of uterine abnormalities in infertile women. materials and methods: the infertile women who visited royan institute and referred to 3-dhs consecutively, prior to ...

circularly-polarized antenna is built based on new siw(substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (rhcp) and fabricated in two separate layers. a broadband impedancebandwidth of 13.9% and a rhcp axia...

myeloid sarcoma (ms) is a tumor mass consisting of myeloblast with or without maturation occurring at an anatomical site other than the bone marrow. incidence of ms ranges from 1-9% and is most commonly misdiagnosed as non hodgkins lymphoma or poorly differentiated carcinoma. ms can occur in various sites but nasal cavity involvement is rare. here we report acaseof ms presenting as nasal polyp ...
