Specific heat determination of plant barrier lipophilic components: biological implications.

The specific heat of isolated plant cuticles and their corresponding cuticular waxes have been measured for the physiological temperature in the range of 273-318 K at regular intervals. C(p) values ranged from 1.5 up to 4 J K(-1) g(-1) indicating a high cohesion, at the molecular level, of the molecular lipophilic components that constitute the plant cuticle. Second order phase transitions arou...

a determination of specific heat and thermal conductivity of pomegranate components (alak variety)

to design the equipment and facilities for preservation, storage and processing of pomegranate, it is necessary to know the specific heat and thermal conductivity of the fruit components. the specific heat of exocarp, mesocarp and of seeds of pomegranate were assessed at three moisture content levels (30, 50 and 76% for seed and mesocarp; 15, 35 and 52% for exocarp) and at four temperature leve...

Lipophilic components of different therapeutic mud species.

OBJECTIVE Mud, which contains organic and mineral ingredients, is used for the treatment of several degenerative diseases. It has been proposed that beneficial effects of mud are not only related to its local thermal effects, but also to its chemical components. Unlike hydrophilic components, the lipophilic components of the mud extract have not been described precisely thus far. Thus, we aimed...

Measurement of temperature-dependent specific heat of biological tissues.

We measured specific heat directly by heating a sample uniformly between two electrodes by an electric generator. We minimized heat loss by styrofoam insulation. We measured temperature from multiple thermocouples at temperatures from 25 degrees C to 80 degrees C while heating the sample, and corrected for heat loss. We confirm method accuracy with a 2.5% agar-0.4% saline physical model and obt...

Adsorptive Stripping Voltammetry in Lipophilic Vitamins Determination

The aim of this contribution was to check if adsorptive stripping differential pulse voltammetry (AdSDPV) is suitable tool for sensitive simultenous electrochemical detection of lipophilic vitamins. Retinol (vitamin A1), cholecalciferol (vitamin D3), α-tocopherol (vitamin E) and phylloquinone (vitamin K1) were selected as representatives. All electrochemical measurements were performed in two s...
