We report the case of a 35-year-old woman who developed pulmonary alveolar proteinosis requiring multiple lavage treatments, in association with household exposure to ventilation system dust comprised at least partially by a cellulose fire-resistant fibrous insulation material. Scanning electron microscopy with energy-dispersive x-ray analysis documented the presence of spectral peaks consisten...

Surge testing of motor coils has been an industry practice since J. L. Rylander published “A High Frequency Voltage Test for Insulation of Rotating Electrical Apparatus” in Transactions of the AIEE, in February of 1926. Since that time the use of surge testing to diagnose failing or damaged insulation in motors has advanced greatly. In 1926, the indication of a turn-turn insulation failure was ...

This econometric study assesses the efficiency of the income tax credit system implemented in France in 2005 on households’ retrofitting investment decisions, focusing on insulation measures. A logit model with random individual effects is estimated using an unbalanced panel of 23,879 households surveyed over the period 2002‐2011. An estimation in difference is p...

For investigating the detail effects of the vibration absorbers in the cavity of the double-layer wall (DLW), a vibro-acoustic numerical model was developed and the behavior of the system was simulated by the finite-difference time-domain method (FDTD method). By comparing the results for various cases, the mechanism of the vibration absorber in the DLW and the effects of the location side and ...

Fresh fruits and vegetables has become a public concern from the food security aspect. And the prediction of shelf-life loss under the fluctuated temperature becomes one of the key problems in food supply chain operation. So this paper identifies the impact aspects of produce decaying during distribution. For the key temperature factor, the process is divided into three phases: sorting, traveli...

power transformers are key components in electrical power supplies and their failure could cause severe consequences on continuity of service and also generates substantial costs. identifying problems at an early stage, before catastrophic failure occurs, is a great benefit for reliable operation of power transformers. frequency response analysis (fra) is a new, well-known and powerful diagnost...

found in the bipolar pacing system of our patient, probably because the insulation break was a tiny one confined to the outer insulation coating and allowing just a small amount of fluid intrusion during the two month period postimplant, and minimal leakage of current. Additionally, the impedance of the anode and the external wire, over which the fluid was accumulated, was not very low since an...

The objectives of the present study were to evaluate the effects of scrotal insulation on sperm production, semen quality, and testicular echotexture in Bos indicus and Bos indicus x Bos taurus crossbred bulls. In one experiment, B. indicus bulls (n=12) were allocated to control and whole-scrotum insulation groups, while in a second experiment, crossbred bulls (n=21) were allocated into control...
