Hot brines and recent iron deposits in deeps of the Red Sea
Sedimentary iron and heavy-metal deposits of undetermined size have been found in the middle of the Red Sea some 2000 meters below the surface of the sea. This discovery has been made from the Research Vessel Atlantis II, which is still at sea engaged in a series of oceanographic investigations which ultimately will end in November 1965, after the ship has circumnavigated the globe. The discovery

Delaware River water quality Bristol to Marcus Hook, Pennsylvania, August 1949 to December 1963
During the 14-year period from August 1949 to July 1963, the U.S. Geological Survey, in cooperation with the city of Philadelphia, collected samples of river water once each month in the 43-mile reach of the Delaware River from Bristol to Marcus Hook, Pa., and daily at Trenton, 10 miles upstream from Bristol. This part of the Delaware is an estuary into which salt water is brought by tides; fresh

Infectious pancreatic necrosis: its detection and identification
Ultimate control of infectious pancreatic necrosis (IPN) in hatcheries depends largely upon learning where the virus occurs. To detect the presence of virus either susceptible fish or susceptible fish cell cultures may be used as test systems. In modern virology, it is generally agreed that cell cultures are more convenient, are usually a much more sensitive test system, and allow more rapid deter

Correlation between chemical structure and rodent repellency of benzoic acid derivatives
Sixty-five benzoic acid derivatives were either prepared or obtained from commercial concerns, tested for rat repellency, and their indices of repellency computed. The data from these tests were considered analytically for any correlation between chemical structure and rat repellency. The results suggest a qualitative relationship which is useful in deciding probability of repellency in other co
