Engine intake noise of automobile is another important noise that irritates drivers and passengers. The intake noise is narrow-banded low frequency noise. And it varies with engine rpm and throttle condition. Active Noise Control (ANC) technique is superior to passive noise control for this low-frequency noise. ANC is applied to four-cylinder automobile engine intake system. Normalized FXLMS (F...

The responsiveness of central nervous system alpha 2-adrenergic receptors in the neural control of renal function was compared in conscious spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY) on normal or high sodium intake (3-4 weeks of 1% NaCl for drinking). The responsiveness of central alpha 2-adrenergic receptors was determined by comparing among groups the dose-...

Guidelines have recommended significant reductions in dietary sodium intake to improve cardiovascular health. However, these dietary sodium intake recommendations have been questioned as emerging evidence has shown that there is a higher risk of cardiovascular disease with a low sodium diet, including in individuals with type 2 diabetes. This may be related to the other pleotropic effects of di...

The responsiveness of central nervous system a2-adrenergic receptors in the neural control of renal function was compared in conscious spontaneously hypertensive rats (SHR) and normotensive Wlstar-Kyoto rats (WKY) on normal or high sodium intake (3-4 weeks of 1% NaCl for drinking). The responsiveness of central aradrenergk receptors was determined by comparing among groups the dose-response cur...

Stronger environmental awareness as well as actual and future legislations increase the demands on diagnosis and supervision of any vehicle with a combustion engine. Particularly this concerns heavy duty trucks, where it is common with long driving distances and large engines. Model based diagnosis is an often used method in these applications, since it does not require any hardware redundancy....

Dietary intake was assessed in 50 patients in hospital by using a dietary history method and computer based system for data collection and standard food tables to calculate the composition of nutrients. The results were compared with those from a weighed assessment that was calculated by using both food tables and manufacturers' food analyses. The use of the food tables overestimated mean (SEM)...

To evaluate the relationship between sodium intake and the activity of the sympathetic nervous system in patients with essential hypertension, plasma catecholamine levels were measured in 49 essential hypertensive patients and 38 age-matched normal subjects under regular-, high-, and low-sodium diets (mean 24-hour sodium excretions; 116 +/- 8, 267 +/- 29, 31 +/- 7 mEq/day, respectively). The le...

organochlorine and organophosphate pesticides are likely to pollute lipid-containing food sources, like milk (3-5% fat), owing to their lipophilicity, thereby jeopardizing the benefits of milk as a health food. pesticide load in bovine milk may be from the leaching of pesticides persisting in the adipose tissue of the animal, or through direct contamination during milking or improper handling o...

nutritional status during adolescence plays an important role in human lifecycle. the aim of this study was nutritional status and dietary intake among adolescent girls. in a cross sectional study, using two stage cluster sampling 256 adolescent girls were randomly selected from 8 semnan secondary schools. weight and height were measured and body mass index (bmi) was calculated. in adolescents,...
