Effect Of Temperature On Algal Removal By Alum Coagulation, Muhammad Anis H. Al-Layla, E. Joe Middlebrooks, Donald B. Porcella
Effect Of Temperature On Algal Removal By Alum Coagulation, Muhammad Anis H. Al-Layla, E. Joe Middlebrooks, Donald B. Porcella
Reports
Questions about the effect of temperature on algal cell coagulation and the relationships between algae removal and temperature, alum dosage, paddle speed, flocculation time, and settling time are answered. The investigations consisted of two series of tests: Studies on algae cultured under laboratory control, and algae in wastewater stabilization ponds. The jar-test technique was used for the coagulation of algal suspensions by alum. Coagulation of algae is caused mainly by the insoluble flocs of aluminum hydroxide. Other aluminum species also have coagulative properties but are far less effective. The destabilization of algal colloids results from enmeshment within the hydroxide precipitates, …

Ba
For almost a century (42, 139) certain yeast, or yeastlike parasites of fruits and seeds have been known. They occur on a wide variety of crop plants and cause such diseases as stigmatomycosis," "yeast-spot," "eye spot," and "internal rot." They seemingly represent a phylogenetic unit. They have cylindrical or pyriform asci, and the hyaline ascospores often are characteristically arranged in two fascicles lying end to end. All have acicular ascospores. (See figs. 2, a-c; 5 , c; 11, hand i; 12, A; 13, c-h; 15,j-k.) They have similar habitats, and several species may simultaneously occur in the same fruit or …

Heart Rate As An Indicator Of Metabolism In Free-Living Uinta Ground Squirrels (Spermophilus Armatus), Steve F. Johnson
Heart Rate As An Indicator Of Metabolism In Free-Living Uinta Ground Squirrels (Spermophilus Armatus), Steve F. Johnson
Biology
Metabolic rates and heart rates were linearly correlated in nonhibernating, Uinta ground squirrels (Spermophilus arrnatus) at air temperatures in and below the thermoneutral zone. This relationship measured in the laboratory was used to estimate the metabolism of 4 squirrels in the field for 7 days from telemetered heart rate and the metabolism of 2 squirrels in the laboratory for 8 days. The accuracy of heart rate as an indicator of the metabolism of Uinta ground squirrels is evaluated. Measurements of D20 and H2180 turnover rates made simultaneously with heart rate did not yield …
Selection At The Molecular Level: Competition Between Members Of The Lambdoid Family Of Bacteriophages, Kandy D. Baumgardner
Selection At The Molecular Level: Competition Between Members Of The Lambdoid Family Of Bacteriophages, Kandy D. Baumgardner
Biology
Competition between lambda and 434 hy mi and lambda and phi80 was investigated, making use of long-term transfer experiments to follow evolutionary trends of the phage populations. The competitive superiority of lambda at 37 C is shown by the elimination of 434 hy mi and phi80 from mixed populations. A reversal in the outcome of competition between lambda and phi80 was observed when the phages were grown at low temperature. The temporal course and final outcome of competition appear to be genetically determined responses of the phages to their specific environment. No relation between phage yield per cell and advantage …
Fine Structural Aspects Of Development Of Eimeria Ninakohlyakimovae In Cultured Cells, Gary L. Kelley
Fine Structural Aspects Of Development Of Eimeria Ninakohlyakimovae In Cultured Cells, Gary L. Kelley
Biology
Development of Eimeria ninakohlyakimovae from intracellular sporozoites to mature first-generation merozoites was studied. Monolayer cell line cultures of ovine trachea, kidney, and thyroid cells were inoculated with sporozoites of E. ninakohlyakimovae. Cultures containing parasites were fixed at the appropriate number of days after inoculation and prepared for examination. Sporozoites, trophozoites, schizonts, and merozoites grown in cultured cells were examined with the electron microscope. Intracellular sporozoites had ultrastructural characteristics similar to those of extracellular sporozites, except that apparently functional micropores were observed. During transformation of sporozoites to trophozoites, the conoid, annuli, and subpellicular tubules, as well as some portions of …

Carbaryl Penetration And Metabolism In The Alfalfa Leafcutting Bee, Megachile Pacifica (Panzer), Guirguis N. Guirguis
Biology
Carbaryl penetration into and metabolism by adult alfalfa leafcutting bees, Megachile pacifica (Panzer), was studied in relation to sex, age, exposure to piperonyl butoxide, and after feeding with chlorcyclizine, phenobarbital, or aminopyrine. Specifically the study included 1- and 4-day-old male bees and 4-day-old female bees representing LD50 values of about 240, 51, and 262 µg/gm and carbaryl-piperonyl butoxide synergist ratio of 12, 53, and 15, respectively. Penetration rates/hour and percent penetrated were calculated for the first 8 hours after application. More carbaryl penetrated more rapidly into the most sensitive insects, but the differences were not statistically significant. Piperonyl butoxide, …

Contractions Of Rabbit Testes In Vitro: Permissive Role Of Prostaglandins For The Actions Of Calcium And Some Smooth-Muscle Stimulating Agents, James Lee Hargrove
Contractions Of Rabbit Testes In Vitro: Permissive Role Of Prostaglandins For The Actions Of Calcium And Some Smooth-Muscle Stimulating Agents, James Lee Hargrove
Biology
The purpose of this paper is to explore the relationship among prostaglandins, calcium, epinephrine, serotonin, and acetylcholine. Prostaglandin E2(PGE2) initiated rhythmic contractions in rabbit testes in vitro. Inactive testes did not respond to calcium ion, acetylcholine, or serotonin; after contractions had been stimulated with PGE2, all of these agents caused the capsule to contract. Epinephrine and histamine induced contractions in non-motile capsules without releasing prostaglandin-like material into the bathing medium. Exogenously administered PGE2 potentiated histamine or epinephrine-induced testicular contractions. Calcium ion was required in the action of PGE2 in a dose-dependent …
Fine Structural Study Of The Early Endogenous Stages Of Eimeria Magna, Harry D. Danforth
Fine Structural Study Of The Early Endogenous Stages Of Eimeria Magna, Harry D. Danforth
Biology
The sporozoites and 1st, 2nd, and 3rd generation schizonts of Eimeria magna were studied. The tissue in which these stages were found was fixed Karnovsky's fixative, and post fixed in 2.5% osmium tetroxide. Some of the tissue was prestained with uranyl acetate and phosphotungstic acid before examination with the electron microscope. Intracellular sporozoites observed in 24-hr ligated intestine had fewer amylopectin granules, and more mitochondria than those fixed immediately after inoculation. One or two Golgi apparatuses were seen in close association with the nucleus. The inner membrane complex of the pellicle was still intact, and no indication of nuclear division …

CelVantes, almost as if he would at all costs avoid the incredible fireworks of Chaucer's Dame Prudence as she counsels Melibee on justice, from a vast cascade of learning and proverbial wisdom, in his Prologue to Don Quixote, says "I am, moreover, extremely lazy when it comes to hunting up authors who will say for me what I am unable to say for myself. And if I am in a state of suspense and my thoughts are woolgathering, you will find a sufficient explanation in what I have just told you." Then his clever friend advises the use of "scraps …

Impact Of The Black-Tailed Jackrabbits (Lepus Californicus) On Vegetation In Curlew Valley, Northern Utah, Mark Westoby
Impact Of The Black-Tailed Jackrabbits (Lepus Californicus) On Vegetation In Curlew Valley, Northern Utah, Mark Westoby
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The interrelations of black-tailed jackrabbits and the desert-shrub vegetation on which they were feeding were studied in Curlew Valley, Northern Utah. The vegetation was described as a three-cornered continuum, the corners being types dominated respectively by Artemisia tridentata, Atriplex confertifolia, and Sarcobatus vermiculatus.
Jackrabbit diet was studied by microscopic analysis of plant fragments in stomachs from shot animals. The method was inaccurate, apparently because the ratio of identifiable tissues to all ingested tissues was very low, and varied between plant taxa, and seasonally. This problem seems intractable for desert shrub vegetation.
The diet was similar to that …

Annual Periodicity In A Free-Living Hibernator, The Uinta Ground Squirrel, Fred L. Knopf
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study documents the timing of seasonal events and associated changes in body weights of Uinta ground squirrels (Spermophilus armatus) that live at three different altitudes. The investigation provides detailed field data for biologists investigating circannual rhythms and hibernation in the laboratory.
Ground squirrels aroused and subsequently emerged from hibernation in an overlapping sequence: adult males first, followed by adult females, yearling females and yearling males. Within limits some climatic condition(s) delayed emergence and increased the overlap in emergence sequence. The duration of seasonal activities above ground averaged about 90 days for adult and yearling squirrels. Juveniles were …
