A Taxonomic Revision Of The Weevil Genus Tychius Germar In America North Of Mexico (Coleoptera: Curculionidae), Wayne E. Clark Apr 1971

A Taxonomic Revision Of The Weevil Genus Tychius Germar In America North Of Mexico (Coleoptera: Curculionidae), Wayne E. Clark

Brigham Young University Science Bulletin, Biological Series

A study of morphological characters of 4,000 adult weevils used in preparing a key and descriptions indicates there are fifteen North American species in the genus Tychius Germar. Adults occur on plants in the genera Astragalus, Baptisia, Hedysarum, Lotus, Lupinus, and Oxytropis.

The genus is divided into two species groups. The T. sordidus group appears to have representatives in the Old World fauna, but the T. semisquamosus group is probably native to North America. New names, Tychius caesius, and T. hirsutus are proposed for T. armatus Green, 1920 (not Tournier, 1873), and T. hirtellus LeConte, 1876 (not Tournier, 1873) respectively. …


Notes On Eriogonum - Vi : A Revision Of The Eriogonum Microthecum Complex (Polygonaceae), James L. Reveal Apr 1971

Notes On Eriogonum - Vi : A Revision Of The Eriogonum Microthecum Complex (Polygonaceae), James L. Reveal

Brigham Young University Science Bulletin, Biological Series

This revision discusses seven closely related species of Eriogonum (Polygonaceae) found in the western United States of North America. One of the two major species, E. microthecum, is composed of nine varieties which range over a wide area of the Far West. The other major species, E. effusum, is found over a more restrictive geographical range mainly east of the Continental Divide. The remaining five species are primarily restricted to the Colorado-Green river drainage basin of Utah, Colorado, New Mexico, and northern Arizona. Together these entities form the core of a group of plants known as Section Corymbosa. …

A Taxonomic Study Of Crotaphytus Collaris Between The Rio Grande And Colorado Rivers, William Ingram Iii, Wilmer W. Tanner Apr 1971

A Taxonomic Study Of Crotaphytus Collaris Between The Rio Grande And Colorado Rivers, William Ingram Iii, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

Little work has been done previously on the taxonomy of Crotaphytus collaris baileyi. This and the demonstration by Fitch and Tanner that C. c. baileyi is a heterogeneous grouping prompted the present study. Only the populations of the type material, the Upper Colorado River Basin, and the Chihuahuan Desert were studied. Multivariate, variance, canonical and discriminant analyses of external characters were performed, and pattern-coloration characters were examined on living specimens.

The results of the analyses show significance between all three populations. The discriminant functions distinguished between the populations with 80% reliability and patternal characters were discriminatory with near 100% reliability. …

The Clinical Course Of Duodenal Ulcer Associated With Hyperparathyroidism, Melvin A. Block, Boy Frame, Thomas A. Fox Jr. Mar 1971

The Clinical Course Of Duodenal Ulcer Associated With Hyperparathyroidism, Melvin A. Block, Boy Frame, Thomas A. Fox Jr.

Henry Ford Hospital Medical Journal

In 98 patients with primary hyperparathyroidism, 15 had objective evidence of duodenal ulcer disease. Following operative correction of the hyperparathyroidism, improvement of duodenal ulcer disease occurred usually, but not uniformly, if unassociated with non-beta islet cell tumors. Correction of hyperparathyroidism in patients with the Zollinger-Ellison syndrome does not significantly influence the peptic ulcer which should be given primary aggressive surgical treatment.


A Replacement Prosthesis For The Hip: A Preliminary Report, H. M. Frost, E. R. Guise Mar 1971

A Replacement Prosthesis For The Hip: A Preliminary Report, H. M. Frost, E. R. Guise

Henry Ford Hospital Medical Journal

Because of theoretical as well as practical difficulty in the total hip endoprostheses available to orthopaedic surgeons at the present time, an anlysis of the present and potential difficulties reveals that substitution of a roller-bearing for the present slider-bearing prosthesis and the establishment of a larger end-bearing surface on the acetabular side would be of benefit. Thus, the Ring prosthesis was re-designed to satisfy these hopes. A modification of the Ring's approach gives complete acetabular exposure and control of the prosthetic insertion. This is a preliminary report describing the design modifications of a prosthesis, presently under investigation, and illustrated by …


Fever In Neoplastic Disease, Samuel L. Rosenthal, Robert W. Talley Mar 1971

Fever In Neoplastic Disease, Samuel L. Rosenthal, Robert W. Talley

Henry Ford Hospital Medical Journal

A comparison is made between incidence of fever in 132 patients with various types of disseminated cancer and 57 patients with diseases other than cancer during a 2- month observation period. Fifty-three febrile episodes were observed in cancer patients. Of these, 15 were of undetermined origin and 6 were noninfectious; none of the episodes occurred immediately following surgery. In the control group of 57 patients, there were 12 febrile episodes; of these, 7 were due to proven bacterial infection, 2 were due lo possible bacterial infection, and 3 were of undetermined etiology. All three febrile episodes in this latter group …


Bulletin No 3768 - Submitting Plants For Disease Identification, M D. Marcley Feb 1971

Bulletin No 3768 - Submitting Plants For Disease Identification, M D. Marcley

Bulletins - 3000 - 3999

THERE are several important points to remember when submitting plant material for disease identification by the Department of Agriculture's Plant Pathology Branch.

Firstly it is very important to collect a suitable sample because it is very difficult to determine the cause of a plant disease by looking at a completely dead plant. The sample should include the entire plant (before it is completely dead) including roots and soil. Then all the effects of the disease can be seen. For example leaf yellowing, dead areas of the stem, collar rot, root rot, eelworm damage, and disease of the water and food …

Basic Pig Breeding, P Mcnamara Jan 1971

Basic Pig Breeding, P Mcnamara

Journal of the Department of Agriculture, Western Australia, Series 4

PROFITABLE pig raising depends on the tumoff of efficiently grown animals. Breeders should be selected for growth rate, and proper care of the breeding sow will ensure that her litters are large and healthy.

A rapid increase in the number of breeding sows in Western Australia suggests that some relatively inexperienced breeders may have started raising pigs. This article sets out the best pig breeding methods as a guide to beginners and a reminder to more experienced pig raisers.

Effect Of Freezing And Thawing On Uptake Of Amino Acids Into Human Erythrocytes, Richard Moore, Rita Parenti, I. Rena Bizios Jan 1971

Effect Of Freezing And Thawing On Uptake Of Amino Acids Into Human Erythrocytes, Richard Moore, Rita Parenti, I. Rena Bizios

Journal of the Minnesota Academy of Science

ABSTRACT - The transport of "C-amino acids into human erythrocytes and into erythrocytes which had been frozen and thawed was studied experimentally. The relative rates of uptake were found to be (in decreasing order): phenylalanine, leucine, alanine, trythophan, and glycine. Freezing (using gycerol as the cryoprotective additive) and thawing had no significant effect on either the magnitude of the rate constants or on the order of the above relative rates of amino acid uptake into erythrocytes suspended in isotonic TRIS-HCl buffer.


Historical Development Of Cardiac Pacing, Paul M. Zoll Jan 1971

Historical Development Of Cardiac Pacing, Paul M. Zoll

MCV/Q, Medical College of Virginia Quarterly

I would like to discuss the development and historical aspects of cardiac pacemaking from a personal point of view, presented as it appeared to me over the years. This approach is biased, selective, and incomplete, but I think as informative as I can make it.

Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh Jan 1971

Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh

Brigham Young University Science Bulletin, Biological Series

This is a review of the use of public lands in Wah Wah and Pine Valleys in western Utah for grazing of livestock, mining, and other private enterprises. The total area of the two valleys is approximately 1,440 square miles of which about 30 square miles are privately owned. From the time grazing of domestic livestock was initiated in the 1870's and 1880's until 1934, the land was free public domain and was grazed on a first-come, first-served basis. Passage of the Taylor Grazing Act in 1934 ended free use of public lands. Existing evidence indicates that by 1934 the …


Evolution Of The Iguanine Lizards (Sauria, Iguanidae) As Determined By Osteological And Myological Characters, David F. Avery, Wilmer W. Tanner Jan 1971

Evolution Of The Iguanine Lizards (Sauria, Iguanidae) As Determined By Osteological And Myological Characters, David F. Avery, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The problem of phylogenic relationships within the iguanine phyletic line and the Madagascar iguanids have been investigated in order to explain the discontinuous distribution exhibited by the members of the family Iguanidae. Owing to inconclusive results from cytology and histological methods, the comparative morphology of the anterior osteology, myology, tongues, and hemipenes were used to determine relationships.

An examination of the above structures of the members of the iguanine phyletic lines and a comparison with the Madagascar iguanids indicates the following: ( 1 ) The Madagascar genera Chalarodon and Oplurus appear to be more closely related to each other than …
