Pilzgeschichten: Wissenswertes aus der Mykologie

Wer beim Wort Pilze nur an leckere Champignons und Steinpilze oder giftige Knollenblatter- und Fliegenpilze denkt, wird von diesem Buch uberrascht sein. Denn Pilze sind ungeheuer vielgestaltig und besiedeln die verschiedensten Lebensraume: Manche sind mikroskopisch klein und wirken als Krankheitserreger bei Menschen, Tieren und Pflanzen.

Carbonate Systems during the Oligocene-Miocene Climatic Transition

The Oligocene and Miocene Epochs include an important stages within the Cenozoic international cooling that led from a greenhouse to an icehouse Earth. contemporary significant advances within the figuring out and time-resolution of weather occasions happening at present, in addition to the proliferation of experiences on Oligocene and Miocene shallow-water/neritic carbonate structures, invite us to reconsider the importance of those carbonate platforms within the context of alterations in weather and Earth floor techniques.

Analysis of Seawater

This booklet covers all features of the research of seawater together with the main complicated actual concepts. Sampling, the decision of anions, disolved gases, atomic absorption, tracking radioactive degrees, non-metallic compounds are all mentioned in flip

Example text

If the sample was initially at a temperature of t C when taken at a depth d meters, its correct pH, in situ, is given by the expression : pH8 = pHm - o: ( t - tm) neglecting pressure effects. 1. EXPERIMENTAL QUANTITIES 31 pHtt = pH. - {3d Values for the coefficients a and {3 are given in Part VI, Tables III and IV. The temperature correction should always be applied before making the calculations described later. The pressure variation is negligible for samples taken above about 500 m. 2. TOTAL ALKALINITY DETERMINATION A.

A. Calculate the initial pH of the water from Table III. b. Look up the corresponding aH value from Table V. Bicarbonate concentration : [HC03]I - = carbonate alkalinity X J aH l aH + 2K l J as millimoles/liter. 5. ON CONCENTRATION [C03]2 Required: Carbonate alkalinity, chlorinity or salinity, initial temperature, pH, and the temperature at which the pH was measured, the dissociation constant K. a. Calculate the initial pH of the water from Table III. b. Look up the corresponding aH value in Table V.

87 will be effective for the pH range 7-9 . With a satisfactory meter and electrodes the standardization need be repeated only once a day. Place the s amples in a thermostatically controlled water bath until they attain a temperature within ± 3 C of the temperature at which the pH meter was standardized. (If the temperatures of s amples and buffer differ by more than 3 C, errors become appreciable as the temperature compensator on the pH meter does not effect a complete temperature correction. ) If the electrodes have just been immersed in buffer they should b e washed wi�h water and gently dried With a little paper tissue, otherwise the electrodes are trans­ ferred from one solution to another without rinsing or wiping.
