1.11: Understanding the Importance of Buffers in Biological Systems

A first buffer (commonly, pH=7.0) is used to make major adjustments; then, a second buffer (pH=4.0) is used to make fine adjustments. The pH meter will have two different dials - one for major adjustments and one for fine adjustments. Measure the pH of your buffer solution. Prepare 32 ml of a 1:4 dilution of your buffer.

Bronfenbrenner's Ecological Systems Theory

Relevance Today. Bronfenbrenner's ecological systems theory posits that an individual's development is influenced by a series of interconnected environmental systems, ranging from the immediate surroundings (e.g., family) to broad societal structures (e.g., culture). These systems include the microsystem, mesosystem, exosystem, …

The Biological System of the Elements | SpringerLink

A Biological System of the Elements (BSE) has been established (Sect. 2.4), which takes interelemental correlations, the biological function and the uptake form of individual elements into consideration. If the relationship in between these functions of elements is out of balance the inorganic contamination might have a toxicological effect.

The biosocial: sociological themes and issues

The biosocial turn within sociology. Against social constructionist tendencies to reduce the body to a mere effect of language or power‐structures, the turn to the body in sociology and social theory has been probably amongst the first to attempt a reincorporation of biological writings into sociology and social theory (Turner, 1984; Freund, 1988; …
