A prospective panel study, in which personal exposure was monitored, was conducted among preschool children in Helsinki between October 1990 and June 1991. The aims of the study were: 1) to assess children’s personal weekly exposure to nitrogen dioxide (NO2), 2) to investigate the association of seasonal and weekly NO2 exposure with respiratory health and 3) to compare different exposure assess...

the effects of pulsed electric field (pef) on the cell disintegration of sugar beet were studied. field strength (0.5kv/cm to 6kv/cm), pulse number (1 to 100 pulses) and capacity of capacitors (0.5 f to 32 f) were evaluated on degree of cell disintegration and consumed energy in pef treatment. the field conditions of 1 and 2 kv/cm, 8 f with 20 and 10 pulses respectively disintegrated the cel...

Pulsed electric field (PEF) and mild thermal pretreatments at 60 °C (T60) may help preserve texture of plant tissue during processing through pectin modification. However, potato starch counteract the adhesive role processing. Furthermore, postharvest storage potatoes result in compositional textural changes. Therefore, effect on composition untreated, PEF treated thermally was studied. The rem...

The kiwifruit processing industry is focused on product yield maximization and keeping energy costs waste effluents to a minimum while maintaining high quality. In our study, pulsed electric field (PEF) pretreatment enhanced facilitate peelability specific peeling process valorization of waste. PEF optimization was applied obtain the best treatment parameters. A 32 factorial design response sur...

Between July 1978 and December 1981, 64 infants thought to be at increased risk from sudden infant death syndrome (SIDS) were monitored at home for central apnoea. Twenty four of the infants had had a 'near miss' episode at age, median (range), 6 (1 to 33) weeks, and of these infants 22 had had 335 alarms for apnoea by age 6 months. Stimulation by shaking was carried out on 38 occasions and bag...

Electroporation is a phenomenon occurring due to exposure of cells to Pulsed Electric Fields (PEF) which leads to increase of membrane permeability. Electroporation is used in medicine, biotechnology, and food processing. Recently, as an alternative to electroporation by PEF, Pulsed ElectroMagnetic Fields (PEMF) application causing similar biological effects was suggested. Since induced electri...

INTRODUCTION Preoperative evaluation of a patient is the fundamental component of anaesthetic practice. Inadequate documentation and record keeping on the preoperative evaluation form (PEF) can be a major obstacle to attaining good practice and improving patient outcomes following operative procedures. AIM The aim of the study was to conduct an audit to assess the quality of the preoperative ...

Statistics from the American Diabetes Association reflect that 20.8 million children and adults — 7% of the population in the United States — have diabetes. Of these, 14.6 million have been diagnosed, while the remaining 6.2 million are not aware that they suffer from the disease. The disease is one in which the body does not produce or properly use insulin, a hormone needed to convert sugar, s...

Pulmonary function loss in patients with Duchenne muscular dystrophy (DMD) is progressive and leads to pulmonary insufficiency. The purpose of this study in 10-18 year old patients with DMD is the assessment of the inter-correlation between pulmonary function tests (PFTs), their reliability and the association with the general disease stage measured by the Brooke score. Dynamic PFTs (peak expir...
