Combining new technologies for effective collection development: a bibliometric study using CD-ROM and a database management program.

Librarians have used bibliometrics for many years to assess collections and to provide data for making selection and deselection decisions. With the advent of new technology--specifically, CD-ROM databases and reprint file database management programs--new cost-effective procedures can be developed. This paper describes a recent multidisciplinary study conducted by two library faculty members and one allied health faculty member to test a bibliometric method that used the MEDLINE and CINAHL databases on CD-ROM and the Papyrus database management program to produce a new collection development methodology.

Age-related changes in the density and tensile strength of human femoral cortical bone.

In order to ascertain whether the intrinsic strength of human bone changes with age or not, we have determined the ultimate tensile strength and density of strips of femoral cortical bone. These femora were collected from cadavers varying in age from 13 to 97 years. The results show that both density and intrinsic strength of bone increase up to about the fourth decade of life and then decrease with age. However, the rate of decrease of strength is greater than that of density. This indicates that the density of bone is not the sole determining factor of its strength, and that some other factors play an important part.

Assessment of gait disability in hemiplegics. Hemiplegic gait.

A clinical method of recording gait patterns in patients with hemiplegia is described. The method is directed towards obtaining an objective assessment for research purposes primarily but could also be readily used clinically. The basis of the method is a pathway from which one can obtain measurements of the temporal and distance factors of gait. The data so obtained is processed to produce a comprehensive set of results presented in a readily understandable form. Sample results are illustrated and explained. Possible system improvements and applications are discussed.

Bone water.

A short review is given of the water in bone. Various analyses of bone water content are discussed, and its possible location is considered in relation to the behaviour of water in isolated components of bone. Some of the difficulties encountered in examining such microscopic phenomena as water structure in a heterogeneous system such as bone are also discussed.

Mecillinam: a new antibiotic for enteric fever.

Mecillinam is a new antibiotic related to the penicillins but more active than ampicillin against salmonellae, including Salmonella typhi. Mecillinam must be administered parenterally, but the ester, pivmecillinam, is absorbed from the gut. Eight patients suffering from typhoid fever and one suffering from paratyphoid fever were treated with the antibiotic, and seven responded satisfactorily. One patient could not tolerate pivmecillinam because of vomiting but there were no other adverse reactions. Serum and bile levels of mecillinam were many times the minimum inhibitory concentrations for most salmonellae. The antibiotic is a promising addition to the agents available for treating typhoid.

A method of measuring the temporal/distance factors of gait.

There exist many clinical situations where it is desirable to have some measure of a patient's ability to walk. The complex nature of human locomotion is reflected by the number of parameters that have been measured in previous studies of gait analysis. The temporal/distance factors of gait have been found to be extremely useful as a measure of a person's functional mobility. This paper describes a system which has been developed to measure these parameters of gait.
