Transparent regenerative chambers similar to the type originally developed by Sandison (1928), Kirby-Smith (1933) and Clark and Clark (1942), but with slight modifications of our own (Ezra 1966, 1967) were implanted in the central portion of the pinna (Fig. I). The table of the chamber was well vascularised and ready for bone implantation in three weeks. Autogenous bone was obtained from the sp...

Abstract The EUREF Permanent Network (EPN) currently consists of more than 300 evenly distributed continuously operating Global Navigation Satellite System (GNSS) reference stations. As a result the continuous modernization GNSS systems, equipment stations is subject to changes and upgrades. Changes relating receiver antenna replacement are considered main reason for discontinuities noticed in ...

A small (96-aa) protein, virus protein R (Vpr), of human immunodeficiency virus type 1 contains one hydrophobic segment that could form a membrane-spanning helix. Recombinant Vpr, expressed in Escherichia coli and purified by affinity chromatography, formed ion channels in planar lipid bilayers when it was added to the cis chamber and when the trans chamber was held at a negative potential. The...

Here we are reporting echocardiographic findings of 8 month child with Total Anomalous Pulmonary Venous Connection (TAPVC). All pulmonary veins are draining into a venous chamber (venous confluence) posterior to Left Atrium (LA). This chamber is draining in to persistent left superior vena cava (supradiaphragmatic type) with moderate (TR) and estimated (RV) systolic pressure was 88.2 mm of Hg s...

This study provides the authors' experience along with dosimetric data from the commissioning of two Sensus SRT-100 50-100 kV X-ray units. Data collected during the commissioning process included: a) HVL, b) output (dose rate), c) applicator cone factors, and d) percentage depth dose. A Farmer-type chamber (PTW-N23333), and a thin-window parallel plate ion chamber (PTW-N23342) were used for dos...

Positive psychological characteristics such as optimism, positive affect, gratitude, and related constructs may play an important role in health. In patients with type 2 diabetes (T2D), positive psychological constructs have been associated with superior medical outcomes, including better glucose control and lower mortality rates. The beneficial effects of positive psychological states in T2D a...

The six-chamber cardiovascular system model of Burkhoff and Tyberg has been used in several theoretical and experimental studies. However, this cardiovascular system model (and others derived from it) are not identifiable from any output set. In this work, two such cases of structural non-identifiability are first presented. These cases occur when the model output set only contains a single typ...

Taking a `set' to be a type together with an equivalence relation and adding an extensional choice axiom to the logical framework (a restricted version of constructive type theory) it is shown that any `set' can be well-ordered. Zermelo's rst proof from 1904 is followed, with a simpli cation to avoid using comparability of well-orderings. The proof has been formalised in the system AgdaLight.
