A Preliminary Note on Spirochætosis

Intestinal Fuso-Spirochætosis

Studies Into the Omission of Take-Down Tension System in Circular Kniting Machanes (TECHNICAL NOTE)

This paper reports on an attempt to modify a circular knitting machine such that it would operate without the need for a customary tension system where a kinitting machine can operate without an asymmetric take-down system preliminary results appear promising and warrant further development. 

A New Approach in Preliminary Design of Closed Loop Solar Thermal Systems (RESEARCH NOTE)

In this paper, a model for closed loop solar system is presented and an attempt is made to generalize the model to be utilized for primary design of any solar active thermal system. This model may be used for systems in which gas or a liquid are fluids that flow. Two new parameters, namely, the system heat delivery factor and the system heat absorption factor are introduced in the model. These ...

A Comparison of Underground Opening Support Design Methods in Jointed Rock Mass (TECHNICAL NOTE)

It is of great importance to consider long-term stability of rock mass around the openings of underground structure, during design, construction and operation of the said structures in rock. In this context, three methods namely, empirical, analytical and numerical have been applied to design and analyze the stability of underground infrastructure at the Siah Bisheh Pumping Storage Hydro-Electr...

The Rat as a Carrier of Spirochæta Icterohæmorrhagiæ, the Causative Agent of Weil's Disease (spirochætosis Icterohæmorrhagica)

1. On the basis of these findings, we conclude that the extermination of rats and field mice is a highly important prophylactic measure against Weil's disease. 2. The chemical composition of soil and water plays animportant part in the development of Spirochoeta icterohoemorrhagioe, and consequently in the spread of the disease of which it is the causative agent.
