Mechanical Properties of Biological Tissues
The material response discussed in the previous chapters was limited to the response of elastic materials, in particular to linearly elastic materials. Most metals, for example, exhibit linearly elastic behavior when they are subjected to relatively low stresses at room temperature. They undergo plastic deformations at high stress levels. For an elastic material, the relationship between stress...
متن کاملRapid separation and quantification of abscisic Acid from plant tissues using high performance liquid chromatography.
Abscisic acid (ABA) was purified from soybean (Glycine max [L.]) seed extract using a preparative high performance liquid chromatography (HPLC) procedure. The preparative procedure was rapid (70 minutes per sample), required no prior partitioning for purification and was quantitative as demonstrated with an internal standard of [2-(14)C]ABA, of which 98.9% was recovered.Following purification b...
متن کاملPhytohormone targeting in plant tissues
Methods Homogenization and extraction with organic solvents was done in one microcentrifuge tube and accelerated by crushing the plant material in a vibration mill. The extracts from minute amounts of fresh plant material were immediately purified using a solid-phase extraction (C18, C8, OasisTM HLB cartridges)in combination with ion-exchange and/or immunoaffinity purification. A fast chromatog...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اول'Compartmentation' of acids in plant tissues.
The cells of higher plants, in contrast with those of other organisms, contain relatively large amounts of organic acids. Krebs & Lowenstein (1960) calculated that the concentrations of individual organic acids in Escherichia coli are about 0-01 mM, in liver or kidney cells 0 1 mm, and in yeast cells 1 mm. By using the same type of calculation it can be estimated that many plant tissues contain...
