OBJECTIVE This study examined the effectiveness of microwave ovens in assisting elderly persons with disabilities with cooking food. METHOD The participants were five elderly persons who had gross motor, fine motor, or vision impairments but no cognitive impairments. Before the study, none of the participants owned or operated a microwave oven. In this single-subject design of four phases (AB...
The presence of pyrolytic carbon deposits can cause a number of serious problems in the operation of a coke oven. They can inhibit the flow of gas out of the oven; their removal may cause damage to the refractories and the coke pusher equipment, in particular when the deposition is extensive, and can affect the sealing of the oven so leading to undesirable emissions. Some plants burn off the ca...
This study was performed to evaluate the antioxidant activity of oven-dried tomato powder (OTP) as affected by drying temperature and the effect of OTP on the product quality of pork patties. Three OTP products were obtained by drying of fresh tomato at 60, 80 and 100℃ oven until constant weight was obtained. Total phenolic content of three kinds of OTPs ranged from 1.95 to 5.94 g/100 g. The hi...
To explore whether the alteration of lncRNA expression is correlated with polycyclic aromatic hydrocarbons (PAHs) exposure and DNA damage, we examined PAHs external and internal exposure, DNA damage and lncRNAs (HOTAIR, MALAT1, TUG1 and GAS5) expression in peripheral blood lymphocytes (PBLCs) of 150 male coke oven workers and 60 non-PAHs exposure workers. We found the expression of HOTAIR, MALA...
1. Introduction A multitude of commercial devices transmit in the unlicensed 2.4 GHz ISM band, and these devices are likely to interfere with each other. These effects are compounded in highly populated metropolitan areas with large numbers of microwave ovens, Bluetooth devices, cord-less phones, wireless game controllers, and other devices which occupy the ISM band. This contributes to an ever...
Extended Delignification of Old Corrugated Container and Totally Chlorine Free Bleaching of the Pulp
The paper industry has taken various steps to address environmental concerns and raw material limitations. Among them, paper recycling has been shown to be a viable option. In this study, the alkaline sulfite pulping of old corrugated containers (OCC) to produce bleachable pulp was investigated. A combination of one of the three active alkali levels (14, 16, and 18%; Na2O, and oven-dry weight o...
Zr-PILC synthesis Two grams of a montmorillonite rich clay (for instance Bentonite CAS-No-1302-78-9) in 200 mL of water are stirred for a minimum of 2 hours, but preferably overnight. 50 mL of an aqueous 0.1 mol/L Zirconium(IV) oxychloride octahydrate (ZrOCl2·8H2O; CAS-No-13520-92-8) solution are then dropwise added to the clay dispersion (an isobaric dropping funnel can be used) under strong s...
This is the first of two articles about the physics of microwave ovens. This article deals with the generation of microwaves in the oven and includes the operation of the magnetrons, waveguides and standing waves in resonant cavities. It then considers the absorption of microwaves by foods, discussing the dielectric relaxation of water, penetration depths of electromagnetic waves in matter and,...
