Polyol-ester-based carbon black pastes are used to either coat or penetrate flexible graphite, thereby increasing the thermal contact conductance of flexible graphite between copper surfaces. Paste penetration by up to an effective paste thickness (the volume of the penetrated paste divided by the geometric area of the flexible graphite) of 5 lm increases the conductance by up to 350%, 98% and ...

The method used for counting bacteria in tomato catsups, pulp or paste depends on the use of the Zeiss blood counter. In this method a drop of catsup diluted with two portions of distilled water is placed in the counting chamber so as to cover the space within the moat. This stands for fifteen minutes before counting.and the bacteria in 25 small squares are then counted and an average is obtain...

Sebzeler, insan beslenmesinin hayati bir bileşeni olan önemli tarımsal üründür. Yaygın olarak tüketilen domateste toksik elementlerin varlığı, olası olumsuz sağlık etkileri nedeniyle büyük endişe kaynağıdır. Bu çalışmada, farklı pazarlardan temin edilen 18 adet domates örneğinin kadmiyum ve kurşun içeriği araştırıldı. Örneklerdeki element konsantrasyonları, İndüktif Eşleşmiş Plazma Kütle Spektr...

A fast and low-cost analytical method to determine the concentrations of carotenoids (β-carotene, lutein, lycopene) from mixed standard solutions or fruit extracts (kiwi fruits, tomato paste, pink grapefruit juice, kiwi-pineapple smoothie, apricot nectar) was tested. The methodology based on UV-Vis spectrophotometry Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS). Results show...
