Experimental methods for obtaining fracture data from small specimens
This paper first examines the problems of using impact methods to achieve fast fracture of polymers. On-specimen gauges are employed to obtain the distribution of transient and other stresses in different parts of the specimen. A new method is then introduced that avoids transient forces and achieves crack velocities in small specimens of tough polymers of over 300 m s-l. It provides for the me...
متن کاملBronchoalveolar lavage--obtaining biologic specimens from the respiratory tract surface.
Dating to fifth century BCE in Greece and the Hippocratic Movement of Physicians that created the beginnings of Western Medicine, a combination of bodily fluids and discharges, termed humors, described how the human body functioned. Among the four humors, phlegm was one and was connected to old age and winter (1). Consider that respiratory secretions in the elderly might reflect the cumulative ...
متن کاملUrine culture collected from gel-based diapers: developing a novel experimental laboratory method.
BACKGROUND Urinary tract infection diagnosis is based on urine culture, taken from a midstream collection. Obtaining samples in this manner is difficult in elderly patients suffering from incontinence and in infants. OBJECTIVES (1) Develop a method for urine collection using gel-based diapers and (2) compare culture results from gel-based diapers with those of the same urine, examined by acce...
متن کاملImpact of cleaning before obtaining midstream urine samples from children.
INTRODUCTION Microbiological documentation of one uropathogenic bacterium in significant numbers in urine from patients with typical symptoms is the gold standard for diagnosing urinary tract infection (UTI). Cleaning before collecting midstream urine (MSU) is reported not to reduce the risk of contaminating the sample and was therefore omitted at Hvidovre Hospital as from the autumn of 2006. W...
متن کاملGenetic Diversity of Proteus Mirabilis Isolated from Urine Specimens by Box PCR
Introduction: Proteus mirabilis is one of the common causes of UTI.Multiple molecular methods are used to genotype bacteria.The polymerase chain reaction method is based on repeated sequences using BOXA1R primers for differentiation of bacteria. This study aimed to evaluate the genetic diversity of protease mirabilis isolated from urine specimens. Materials & Methods: In this descriptive cr...
