Non-stoichiometric silicon nitride SiN x , enriched with silicon, is a promising material for the non-volatile resistive memory development. The current studies devoted to investigation of optical properties synthesized in low-pressure reactor at 800 o C different ratios dichlorosilane (SiH 2 Cl ) ammonia (NH 3 ). It was found that films SiH /NH =1/1, 1/2 and 1/3, corresponding bandgap values a...

OBJECTIVE To examine the relation between length of institutionalization and sensory integration in children adopted from Eastern Europe. METHOD The Sensory Integration and Praxis Tests (SIPT) and the Developmental and Sensory Processing Questionnaire were administered to 60 adopted children, 4 years to 8 years, 11 months of age. Thirty had longer institutionalization histories (mean: 34 mont...

This literature survey is performed as a part of the Philips Solid state course It deals with powder formation in silane contain ing plasma s In recent studies substantial progress has been made A detailed powder formation mechanism has evolved which also accounts for the occurence of a so called tran sition Based on the understanding of the particle formation mechanism and the dynamics of part...

UNLABELLED Ear diseases are illnesses which represent a relevant group of morbidity. Otitis media, for instance, still is a public health problem today. OBJECTIVE To correlate hospital morbidity of ear diseases according to data from the Information Technology Department of the Public Health Care System -SUS (DATASUS), through the Hospital Information System (SIH) with the Human Development I...

BACKGROUND Spontaneous intracranial hypotension (SIH) due to cerebrospinal fluid (CSF) leakage at C1-2 poses diagnostic and therapeutic challenges to spine surgeons. Although computed tomography (CT) myelography has been the diagnostic imaging modality of choice for identifying the CSF leakage point, extradural CSF collection at C1-2 on conventional CT myelography or magnetic resonance imaging ...

Spontaneous intracranial hypotension (SIH) is an increasingly recognized syndrome associated with a specific set of clinical and imaging findings; however, determining the site of spinal cerebrospinal fluid (CSF) leakage in these patients is often difficult, and indications for surgical intervention need to be better defined. The authors report on a 55-year-old woman who presented with posture-...

The most common causes of intracranial hypotension include persistent cerebrospinal fluid (CSF) leakage from lumbar puncture, spontaneous CSF leakage, or excessive CSF drainage. Spontaneous intracranial hypotension (SIH) is defined as a syndrome of reduced CSF pressure that occurs in the absence of dural puncture, surgery, or trauma. The pathogenesis is generally thought to be an occult leak of...

Spontaneous intracranial hypotension (SIH) is a syndrome in which hypovolemia of the cerebrospinal fluid (CSF) results in various symptoms. Although its prognosis is usually benign, cases with a rapid neurologic deterioration resulting in an altered mental status have been reported. One of the characteristic radiographic findings in such cases is the presence of bilateral accumulation of subdur...
