Decay Resistance and Physical Characteristics of Wood

Journal of Forestry, 1943
Abstract Various attempts have been made to find a physical characteristic of wood that would indicate its decay-resisting ability. Studies of leached heartwood and of leached and unleached sapwood of western redcedar conducted by the authors and reported in this paper showed no significant influence of either specific gravity or ...

DECAY RESISTANCE IN THE CYPRESS PINES

Australian Forestry, 1966
SUMMARY The resistance of the heartwood and sapwood of several species of the genus Callitris to attack by the brown rot fungus Coniophora olivacea has been compared. The heartwood of the three forms of C. columellaris, and also of C. macleayana proved to be highly resistant to attack. The heartwood of forms of C. preissii was resistant, and that of C.

Politics of decay and spatial resistance

Social & Cultural Geography, 2010
A historical and multi-cultural district called Istiklal challenges the Turkish claim as a secular, culturally Muslim, and ethnically Turkish nation. This region is at the heart of the republic: it is in the capital city of Turkey, Ankara, and within a region called Ulus, i.e.

Natural Decay Resistance of Wood

1975
This part of the Symposium was originally intended to deal with the decay process in resistant wood, as distinct from susceptible wood, but very little work has been done in this field. The present paper deals with the wider field of natural decay resistance. The topic has been comprehensively reviewed by Scheffer and Cowling (1966) and by Kumar (1971).

Time Decay Constants of Resistive Detectors

AIP Conference Proceedings, 2005
Several authors have studied the dependence of the detection efficiency or charge gain of a resistive detector on the counting rate. Most of these results assume a stationary regime and treat the dielectric as equivalent to a simple RC circuit. In order to verify the validity of this model we have investigated the transient behavior of a resistive ...

Fungal decay resistance of wood fumigated with chlorpyrifos

International Biodeterioration & Biodegradation, 2010
Disinfestation is the main purpose of fumigation and no subsequent and sustained protection for longer duration against risk of attack is afforded. The ideal fumigant is infact, one which leaves treated commodity unchanged in all respect. Although the effectiveness of chlorpyrifos as termiticide has been proven in laboratory and field test studies, no ...

The color of the teeth as an index of their resistance to decay

International Journal of Orthodontia and Dentistry for Children, 1933
Abstract 1. 1. A knowledge of the probable future activity of dental caries in prospective patients is helpful to the dentist or specialist in planning his work. 2. 2. This information can be obtained for a child or young adult before decay has started by observing the following factors: 3. 3. Teeth of low caries susceptibility have: (a)

The Decay in Electrical Resistance in Evaporated Gold Films

Japanese Journal of Applied Physics, 1965
The irreversible changes in electrical resistance (time-decay) of gold films evaporated at room temperature were measured as a function of time to know the mechanism of the forming process of evaporated films. An experimental formula was derived for the change in electrical resistance.

Trace resistance and the decay of long-term memory

Journal of Mathematical Psychology, 1972
Abstract A theory of storage in long-term memory is described which characterizes the trace by two properties: strength and resistance. The theory makes four assumptions: (a) The rate of decay of strength equals the force on the trace divided by the resistance. (b) Force is proportional to trace strength and to the similarity of current traces to the
