Contralateral pneumothorax after percutaneous central venous catheter placement has not been previously reported.Three patients who required intubation and mechanical ventilation for acute respiratory failure due to COVID-19 Apparel were identified with a new pneumothorax on routine post-placement chest roentgenogram on the side opposite the cathet
In this paper we image the highly confined long range plasmons of a nanoscale metal stripe waveguide using quantum emitters.Plasmons were excited using a highly focused 633 nm laser beam and a specially designed grating structure to provide stronger incoupling to the desired mode.A homogeneous thin Digital Artwork layer of quantum dots was used to
This paper analyses the impact of foreign aid on economic growth in Nigeria during the period of 1970-2010 making use of annual time series data.The empirical analysis rests on the neo-classical modelling analytical framework and combined several procedures in modern econometric analysis/estimation techniques.Our Reinforcement Braces findings shows
The present paper aims to conduct an experiment that compares different methods of detecting objects in images.Programs were developed to evaluate the efficiency of SURF, BRISK, MSER, and ORB object detection methods.Four static gray images with sufficiently different histograms were used.The experiment also highlighted the need for image preproces
