The Effect Of Thiouracil On The Thyroid Gland Of The Mouse, Patricia Patridge
The Effect Of Thiouracil On The Thyroid Gland Of The Mouse, Patricia Patridge
Iowa Science Teachers Journal
The object of this research was to determine the effect of thiouracil on the thyroid gland of the mouse. The results showed that thiouracil caused a definite increase in the size of the gland and a decrease in the amount of iodine present in the gland. Since thiouracil is considered capable of preventing iodine from binding and producing the thyroxine molecule needed for the normal function of the gland, these results were as expected.

Volunteer Laboratory Assistants In Bscs Biology Program, Lena Keithahn
Iowa Science Teachers Journal
With the introduction of B.S.C.S. Biology and its intense laboratory centered approach into our school curriculum, the need for additional h e l p to check equipment and student findings during class sessions became apparent. The use of volunteer assistants proved to be helpful, not only to the instructor, but also to the student by providing him with an opportunity to be of service to the school and also to carry on supervised research work.

The Influence Of Slenderness Ratios On Triaxial Shear Testing, Eugene R. Moores, J. M. Hoover
The Influence Of Slenderness Ratios On Triaxial Shear Testing, Eugene R. Moores, J. M. Hoover
Proceedings of the Iowa Academy of Science
Determination of the effect of the slenderness ratio on the results of the triaxial test depends, theoretically, on the boundary conditions induced by (a) shape of the test specimen, (b) manner of the transmission of the external load, and (c) deformations. From a practical point of view enough length should be available to develop two complete cones of failure and the length of the specimen should equal the diameter times the tangent of (45 +ø/2) °. Most workers in the field of triaxial testing of soils accept a slenderness ratio of from 1.5 to 3.0. With slenderness ratios …
