Chemical and Physical Properties of Mycobacteriophage D29

European Journal of Biochemistry, 1977
Mycobacteriophage D29 has a head of uniform size (average diameter 65 nm) and regular shape and a tail of variable length. The stability of the bacteriophage is optimal between pH 9 and 10. The virus contain double-stranded DNA and six structural polypeptides, three major and three minor.

Some chemical and physical properties of microsomes

Experimental Cell Research, 1955
Abstract Microsomes from a number of rat tissues have been examined with respect to certain chemical and physical properties. In addition to a Mg-activated ATP-ase, the microsomes contain adenylic kinase and adenylic deaminase. By extrusion of the microsomal gel into 10 −3 magnesium chloride, artificial fibers are obtained with internal structures ...

Chemical and Physical Properties

2003
It is critical to understand the chemical and physical properties of MTBE and other gasoline constituents because they determine how the chemicals behave in the subsurface environment. These properties also determine which physical and chemical technologies are suitable for remediation.

The physical and chemical properties of bronchial secretion

British Journal of Diseases of the Chest, 1974
Bronchial secretion has very special rheological (flow) properties. Serum gives IO times as much dry weight yield as sputum and yet, at low shear rates, sputum is 5 times as viscous as serum. Bronchial secretion is studied mainly as sputum-that is, bronchial secretion plus saliva.

Chemical and Physical Properties of Sulfated Silk Fabrics

Biomacromolecules, 2007
Silk fabrics were treated with chlorosulphonic acid in pyridine for different times. The amount of sulfur bound to silk increased during the first 2 h of reaction and then reached a plateau. The amino acidic pattern of sulfated silk remained essentially unchanged for short reaction times (< or =2 h). Longer reaction times resulted in drastic changes in

Physical and Chemical Properties of Nanocomposite Polymer Electrolytes

The Journal of Physical Chemistry B, 1999
The physical and chemical properties of a new class of lithium conducting polymer electrolytes formed by dispersing ceramic powders at the nanoscale particle size into a poly(ethylenoxide) (PEO)− lithium salt, LiX complexes, are reported and discussed.

The Physical and Chemical Properties of Circumstellar Envelopes

Astrophysics and Space Science, 1995
An overview is given of recent results on some basic properties of the circumstellar envelopes of evolved stars. The focus is on well studied examples which illustrate envelopes of different types and at different stages of evolution. The close connection between the physical and chemical properties of the envelopes is emphasized.

The Soil. Physical, Chemical and Biological Properties

2016
This chapter provides a basic description of soil properties and processes, stressing the concept that the soil is a dynamic entity where complex interactions among its biological, chemical and physical components take place. All these components and properties determine the functioning of the soil for different purposes; this functioning is included ...

Physical and Chemical Properties

2019
High-entropy alloys (HEAs) not only have excellent mechanical properties, but also have good physical and chemical properties. Usually, the resistivity of HEAs is higher than that of metals and alloys, but only lower than that of bulk amorphous alloys, and for some HEA, such as Ta34Nb33Hf8Zr14Ti11, have superconducting behavior. The critical transition

Physical and chemical properties of soybean proteins

Journal of the American Oil Chemists' Society, 1977
AbstractRecent physical and chemical studies are reviewed for Bowman‐Birk and Kunitz trypsin inhibitors, agglutinin, and 7S and 11S globulins of soybeans. Differences between gelation properties of crude 7S and 11S globulin fractions are also discussed.
