To Hospitalize or Not to Hospitalize? Medical Care for Long-Term Care Facility Residents

Examines factors behind frequent hospitalizations of long-term care facility residents, such as limited capacity, physician preferences, and financial incentives. Suggestions include support and training, advanced care planning, and changes in thinking

Purification and electron cryomicroscopy of coronavirus particles.

Intact, enveloped coronavirus particles vary widely in size and contour, and are thus refractory to study by traditional structural means such as X-ray crystallography. Electron microscopy (EM) overcomes some problems associated with particle variability and has been an important tool for investigating coronavirus ultrastructure. However, EM sample preparation requires that the specimen be dried onto a carbon support film before imaging, collapsing internal particle structure in the case of coronaviruses. Moreover, conventional EM achieves image contrast by immersing the specimen briefly in heavy-metal-containing stain, which reveals some features while obscuring others. Electron cryomicroscopy (cryo-EM) instead employs a porous support film, to which the specimen is adsorbed and flash-frozen. Specimens preserved in vitreous ice over holes in the support film can then be imaged without additional staining. Cryo-EM, coupled with single-particle image analysis techniques, makes it possible to examine the size, structure and arrangement of coronavirus structural components in fully hydrated, native virions. Two virus purification procedures are described

Solution of the Problems of Heterogeneous Welds to Nuclear Power Plants

Diplomová práce se zabývá studiem heterogenních svarových spojů uhlíkových a korozivzdorných austenitických ocelí používaných v jaderném průmyslu. Práce obsahuje teoretický popis problematiky svařování heterogenních svarových spojů, svařitelnosti uhlíkových a vysokolegovaných ocelí a posuzuje současný stav používaných heterogenních svarových spojů v energetice. V experimentální části byl navržen postup svařování heterogenních a homogenních spojů potrubí z uhlíkové a korozivzdorné austenitické oceli. Vzorky byly zhotoveny a hodnoceny na základě metalografické analýzy a zkoušce mikrotvrdosti dle Vickerse. Cílem práce bylo rozšíření dosavadních znalostí o těchto heterogenních svarových spojích z hlediska svařitelnosti, životnosti a bezpečnosti jejich provozování na jaderných elektrárnách.The diploma thesis deals with the study of heterogeneous welded joints of carbon and stainless austenitic steels used in the nuclear industry. The work contains a theoretical description of the problem of welding heterogeneous welded joints, weldability of carbon and high-alloy steels and assesses the current state of heterogeneous welded joints used in power engineering. In the experimental part was proposed a procedure for welding heterogeneous and homogeneous joints of carbon and stainless austenitic steel pipes. The samples were made and evaluated on the basis of metallographic analysis and Vickers microhardness test. The aim of the work was to expand the existing knowledge about these heterogeneous welded joints in terms of weldability, service life and safety of their operation at nuclear power plants.345 - Katedra mechanické technologievýborn

CTAS data analysis program

The analysis program (AN) is specifically designed to produce graphic and tabular information to aid in the design and checkout of the Center TRACON Automation System (CTAS). To best reveal CTAS operation and possible problems, data are plotted in many different ways both in detail and summary form. AN has been designed to analyze both radar surveillance data and output data from CTAS. AN has been extensively used to debug and refine CTAS. It is also being used in the field to monitor and assess CTAS performance. AN is continuously refined to keep up with changing needs. The present version of AN grew out of analysis of Denver Center data. However, the AN software has been written to be adaptable to any other facility Center or TRACON. Presently, one can select Denver Stapleton, Denver International, Dallas/Fort Worth International Airport, and Dallas Love Field

The application of biomedical engineering techniques to the diagnosis and management of tropical diseases: A review

This paper reviews a number of biomedical engineering approaches to help aid in the detection and treatment of tropical diseases such as dengue, malaria, cholera, schistosomiasis, lymphatic filariasis, ebola, leprosy, leishmaniasis, and American trypanosomiasis (Chagas). Many different forms of non-invasive approaches such as ultrasound, echocardiography and electrocardiography, bioelectrical impedance, optical detection, simplified and rapid serological tests such as lab-on-chip and micro-/nano-fluidic platforms and medical support systems such as artificial intelligence clinical support systems are discussed. The paper also reviewed the novel clinical diagnosis and management systems using artificial intelligence and bioelectrical impedance techniques for dengue clinical applications
