TWO CASES OF INTESTINAL POLYPUS. By v J H. Boyle Runnals, M.R.C.S., Saltash, Cornwall.. I have published an account of these cases, and more particularly the first one, as an example of the great difficulty so often experienced in diagnosing the causes of intestinal obstruction ; and it is more interesting since the thorough educating discussion upon that subject reported in the March edition o...

Pump failures are an inherent problem associated with the operation of a heart lung machine. This report details the observation and identification of an unusual modular pump failure. Pump stoppage occurred intermittently over a period of two months with two separate Stockert/Shiley Computer Aided Perfusion System (CAPS) consoles. The mechanism was identified as a static discharge transferred t...

In this paper, battery/ultracapacitor hybrid energy storage system (HESS) is proposed for electric vehicles, it is used to large dc-dc converter by using ultra capacitor and battery. It is also use the dc link for the purpose of maintain the peak voltage value. By the help of battery and ultracapacitor they are operate. The battery is used to charging the capacitor in case of discharge the capa...

Non-tuberculous mycobacteria (NTM) are a group of environmental pathogens, which cause a broad spectrum of disease. The incidence of NTM infection is increasing, especially in immunocompromized patients. The past three decades also saw a rapid increase in the incidence of NTM infection involving otherwise healthy subjects. We report a case of cutaneous NTM infection in a 79-year-old Chinese wom...

Vesicle transport is regulated at multiple levels, including regulation by scaffolding proteins and the cytoskeleton. This tight regulation is essential, since slowing or stoppage of transport can cause accumulation of obstacles and has been linked to diseases. Understanding the mechanisms by which transport is regulated as well as how motor proteins overcome obstacles can give important clues ...

We study the causal effect of labor unions on corporate payout policy by using a regression discontinuity (RD) design. Passing a union election leads to an 8.7% lower dividend ratio and a 17.9% lower total payout ratio (including both dividends and share repurchases) than failing an election in the following year. The negative effect of unions on payout is absent in firms located in states with...

Abrupt normalization of hyperthyroid state with antithyroid drugs is reported to precipitate psychosis. We report the development of acute psychosis in a 20-year-old woman, following 30 days use of tablet carbimazole 10 mg for hyperthyroidism due to the multinodular goiter. At the time of presentation, she was euthyroid with a resolution of hyperthyroid status both clinically and biochemically....

This paper uses a 2D system setting in the form of repetitive process stability theory to design an iterative learning control law that is robust against model uncertainty. In iterative learning control the same finite duration operation, known as a trial over the trial length, is performed over and over again with resetting to the starting location once each is complete, or a stoppage at the e...
