Function Of Funnel-Shaped Coral Growth In A High-Sedimentation Environment, Bernhard Riegl, Carlton Heine, George M. Branch Dec 1996

Function Of Funnel-Shaped Coral Growth In A High-Sedimentation Environment, Bernhard Riegl, Carlton Heine, George M. Branch

Marine & Environmental Sciences Faculty Articles

Advantages and disadvantages of a funnel-shaped growth in 2 coral species (Acropora clathrata, Turbinaria peltata) in a high-sedimentation environment (Natal, South Africa) were observed in the field and modeled in a flow tank. Funnel-shaped growth serves different purposes in different hydrographic settings. In calm waters with little currents (in our case deep reef areas, 18 to 25 m) funnel-shaped colonies served as 'sacrificial sediment traps': all sediment trapped inside the funnel was directed towards the centre, where it was concentrated. There, tissues underwent necroses, but all other tissues remained sediment free and healthy. In areas with high currents (in our ...


Long-Term Monitoring And Analyses Of Physical Factors Regulating Variability In Coastal Antarctic Phytoplankton Biomass, In Situ Productivity And Taxonomic Composition Over Subseasonal, Seasonal And Interannual Time Scales, Mark A. Moline, Barbara B. Prezelin Dec 1996

Long-Term Monitoring And Analyses Of Physical Factors Regulating Variability In Coastal Antarctic Phytoplankton Biomass, In Situ Productivity And Taxonomic Composition Over Subseasonal, Seasonal And Interannual Time Scales, Mark A. Moline, Barbara B. Prezelin

Biological Sciences

A 3 yr high-resolution temporal data base related to phytoplankton dynamics was collected during the austral spring/summer periods of 1991 to 1994 in shelf waters adjacent to Palmer Station, Antarctica. Here, the data base is used (1) to quantify the variability in phytoplankton biomass, in situ productivity and taxonomic composition over subseasonal, seasonal and interannual time scales; (2) to elucidate environmental mechanisms controlling these temporal patterns; and (3) to ascertain which phytoplankton markers are most suitable for detecting longer-term (i.e. decadal) trends in phytoplankton dynamics in coastal waters of the Southern Ocean. The Long-Term Ecological Research (LTER) coastal ...


Eumops Perotis., Troy L. Best, W. Mark Kiser, Patricia W. Freeman Dec 1996

Eumops Perotis., Troy L. Best, W. Mark Kiser, Patricia W. Freeman

Mammalogy Papers: University of Nebraska State Museum

Eumops perotis is the largest bat in the United States. The greater mastiff bat resembles other North American free-tailed bats, but is distinguished from other molossids by its large size and lack of long guard hairs on the rump (Barbour and Davis, 1969). E. perotis has the thinnest dentary of any Eumops (Freeman, 1981a).In the United States, E. perotis can be separated from E. underwoodi by its larger size (forearm is 73-83 mm in E. perotis and 65-77 mm in E. underwoodi), darker color, and lack of long guard hairs on the rump. The ears are longer (36-47 mm ...

Functional Analysis Of The Mutations In The Human Cardiac Beta-Myosin That Are Responsible For Familial Hypertrophic Cardiomyopathy. Implication For The Clinical Outcome, Masataka Sata, Mitsuo Ikebe Dec 1996

Functional Analysis Of The Mutations In The Human Cardiac Beta-Myosin That Are Responsible For Familial Hypertrophic Cardiomyopathy. Implication For The Clinical Outcome, Masataka Sata, Mitsuo Ikebe

Open Access Articles

More than 30 missense mutations in the beta-cardiac myosin heavy chain gene have been shown to be responsible for familial hypertrophic cardiomyopathy. To clarify the effects of these point mutations on myosin motor function, we expressed wild-type and mutant human beta-cardiac myosin heavy chains in insect cells with human cardiac light chains. The wild-type myosin was well purified with similar enzymatic and motor activities to those of the naturally isolated V3 cardiac myosin. Arg249-->Gln and Arg453-->Cys mutations resulted in decreased actin translocating activity (61 and 23% of the wild-type, respectively) with decreased intrinsic ATPase activity. Arg403-->Gln mutation ...

Fishery Independent Standing Stock Surveys Of Oyster Populations In Virginia 1996, Roger L. Mann, James Wesson Dec 1996

Fishery Independent Standing Stock Surveys Of Oyster Populations In Virginia 1996, Roger L. Mann, James Wesson

Reports

Extensive description of the Virginia oyster resource and history of its utilization has been given by Haven, Hargis and Kendall (1981), and more recently reviewed by Hargis and Haven (1988). These contributions, among many others, describe a state of continuing decline. The James River, Virginia has served as the focal point for the Virginia oyster industry for over a century, being the source of the majority of seed oysters that were transplanted for grow-out to locations within the Virginia portion of the Chesapeake Bay and much further afield in the Middle Atlantic states (Haven et al, 1981 ). The Rappahannock River ...


The Rna-Binding Site Of Bacteriophage Qβ Coat Protein, Francis Lim, Marc Spingola, David S. Peabody Dec 1996

The Rna-Binding Site Of Bacteriophage Qβ Coat Protein, Francis Lim, Marc Spingola, David S. Peabody

Marc Spingola

The coat proteins of the RNA bacteriophages Qβ and MS2 are specific RNA binding proteins. Although they possess common tertiary structures, they bind different RNA stem loops and thus provide useful models of specific protein-RNA recognition. Although the RNA-binding site of MS2 coat protein has been extensively characterized previously, little is known about Qβ. Here we describe the isolation of mutants that define the RNA-binding site of Qβ coat protein, showing that, as with MS2, it resides on the surface of a large β-sheet. Mutations are also described that convert Qβ coat protein to the RNA binding specificity of MS2 ...

Parasexuality And Heterokaryosis In Fusarium Oxysporum Forma Specialis Cubense, Blanca R. Cortes Dec 1996

Parasexuality And Heterokaryosis In Fusarium Oxysporum Forma Specialis Cubense, Blanca R. Cortes

FIU Electronic Theses and Dissertations

Intra and Inter Vegetative Compatibility Group (VCG) heterokaryon formation was observed in Fusariurn oxysporum f.sp. cubense (Foc). Using the double-pick method to force heterokaryon formation via hyphal anastomosis, 104 pairwise combinations were done between 100 auxotrophic mutants of Foe representing races 1, 2 and 4 in five VCGs. Inter formae speciales heterokaryon formation was also observed on pairings between benomyl resistant Wild Type Testers (WTT) and wild type isolates in 15 VCGs and four different formae speciales. Microconidia analysis of heterokaryons identified both parental phenotypes as well as diploid phenotypes. Colonies with altered and hybrid genotypes were recovered ...

Reporting Hta Losses, Neil Harl Dec 1996

Reporting Hta Losses, Neil Harl

Agricultural Law Digest

Hedge-to-arrive contracts, which in recent years had spread throughout Midwestern agriculture like a virus, pose important but difficult issues on how the losses are reported for federal income tax purposes. Some guidelines are well known and are relevant in determining whether losses are from hedges and thus are ordinary or are capital in nature.


Chemical Communication In House Mice (Mus Musculus): Can They Recognize Gender From The Anogenital, Harderian Gland Or Mouth/Nose Odor?, Dawn Michele Andrews Dec 1996

Chemical Communication In House Mice (Mus Musculus): Can They Recognize Gender From The Anogenital, Harderian Gland Or Mouth/Nose Odor?, Dawn Michele Andrews

Dissertations and Theses

Identifying the sensory systems animals employ to communicate chemically and the function of the chemical signals facilitates further understanding of chemical communication. Increased knowledge of how animals use the olfactory and vomeronasal systems in order to interpret the meaning of body odors will aid in developing a more detailed organization of chemosensory pathways. The message that each body odor contains can change from species to species. The purpose of this thesis was to study three previously untested body odors in house mice (M musculus) for their role in gender recognition of conspecifics. These odors are the anogenital (feces, urine, and ...


Method And Means For Quasi Ad-Libitum Feeding For Gestation Sows In Loose Housing, Steven J. Hoff, Mark S. Honeyman, James D. Mckean, Dwaine S. Bundy, Fernando Perez-Munoz, Steven E. Bryce, William E. Backhaus Dec 1996

Method And Means For Quasi Ad-Libitum Feeding For Gestation Sows In Loose Housing, Steven J. Hoff, Mark S. Honeyman, James D. Mckean, Dwaine S. Bundy, Fernando Perez-Munoz, Steven E. Bryce, William E. Backhaus

Iowa State University Patents

A gestation sow feeding system has a sow bedding enclosure, a gated scale weighing station, an alley connecting the scale weighing station with two separate feeding pens having entry and exist gates, and a bypass gate connecting the alley and the bedding enclosure. The traffic of sows through the system is monitored and controlled by a computer which controls the gates of the system, measures the weight and average daily gain of each sow weighed, and directs the weighed sow to the feeding pen for a ration of feed to permit the sow to adjust to a targeted average daily ...


Automatic Induction Of Rules For Text Simplification, R. Chandrasekar, B. Srinivas Dec 1996

Automatic Induction Of Rules For Text Simplification, R. Chandrasekar, B. Srinivas

IRCS Technical Reports Series

Long and complicated sentences pose various problems to many state-of-the-art natural language technologies. We have been exploring methods to automatically transform such sentences as to make them simpler. These methods involve the use of a rule-based system, driven by the syntax of the text in the domain of interest. Hand-crafting rules for every domain is time-consuming and impractical. This paper describes an algorithm and an implementation by which generalized rules for simplification are automatically induced from annotated training material with a novel partial parsing technique which combines constituent structure and dependency information. This algorithm described in the paper employs example-based ...


The Theme Of "Relevance" In Third World Human Sciences, Syed Farid Alatas Dec 1996

The Theme Of "Relevance" In Third World Human Sciences, Syed Farid Alatas

farid alatas

The fact that the humanities and social sciences in developing societies generally originated in the West has raised the issue of the relevance of these arts and sciences to the needs and problems of Third World societies. This questioning of relevance has led, in turn, to the call for the indigenisation of knowledge in developing societies. While there has been a great deal of discussion on indigenisation, there has been little practice of indigenised humanities and social science. As a result, there are few examples of what indigenous knowledge constitutes from theoretical, methodological and empirical points of view. This paper ...


Competitive Orientations And Motives Of Adult Sport And Exercise Participants, Diane L. Gill, Lavon Williams, Deborah A. Dowd, Christina M. Beaudoin, Jeffrey J. Martin Dec 1996

Competitive Orientations And Motives Of Adult Sport And Exercise Participants, Diane L. Gill, Lavon Williams, Deborah A. Dowd, Christina M. Beaudoin, Jeffrey J. Martin

Kinesiology, Health and Sport Studies

Participants in four different adult sport and exercise programs (running club, exercise classes, cardiac rehabilitation program, senior games) completed measures of competitive orientation and participation motivation. Our samples were older and more diverse than samples of previous research, and their competitive orientations and motives were similarly diverse. Multivariate analyses revealed gender and sample differences. Males were higher than females on competitiveness and win orientation, and runners were less win-oriented than other groups, but overall, all groups were similar to previous college-age samples in competitive orientation. Groups varied on specific motives, with females rating fitness, flexibility, affiliation, and appearance higher than ...

The Evaluation Of Two Types Of Multivariate Analyses Applied To Grassland Vegetation Data From A Reclaimed Coal Mine Area In Southeast Kansas, Usa, Karen Frances Yates

Electronic Thesis Collection

This study presents an analysis of the use of classification and ordination techniques for the detection of sub-communities at a reclaimed coal refuse dump and strip minded area in southeast Kansas. Cover values for 58 grass, forb, and woody species were estimated in 103 systematically positioned plots across the reclamation grassland using the modified Daubenmeyer cover scale. The data were submitted to an array of default and variant classification and ordination analysis programs in order to assess their ability to detect sub-communities. The classifications obtained from the analyses were mapped and analyzed for differences in species composition, diversity, and spatial ...

Whooping Crane Sightings, August-December 1996, Steven Anschutz Dec 1996

Whooping Crane Sightings, August-December 1996, Steven Anschutz

Nebraska Bird Review

Based on observations of the breeding grounds during the summer of 1996, about 170 Whooping Cranes were expected to arrive at the Aransas National Wildlife Refuge in Texas during the fall. The first arrival (two birds) was confirmed on 23 October. A total of 158 birds (143 adults/subadults and 15 young) were wintering at Aransas 1996-97. As of 16 January 1997, six adults and eight subadults, of the number anticipated, had not arrived at the refuge.

The first recorded dates for confirmed observations of migrating Whooping Cranes were 2 August in Canada and 22 September in the United States ...

"Notes On Bird Sightings In Nebraska," From Nebraska Bird Review (December 1996)

Nebraska Bird Review

House Finches. This species has been appearing at my backyard feeders, 10 to 30 feet from our window, for several years, increasing in number each year. They came nearly every day in 1996 except during a period that I associate with post-breeding molt. Numbers varied from one to a maximum of 17 at one time, with 11 counted for the 1996 Christmas Bird Count. We commonly use 7-8 power binoculars to look for a rare Purple Finch. House Finches are noticeably smaller than House Sparrows and slightly larger than American Goldfinches, and feed with both species.

Males have varied in ...

"Book Review," From Nebraska Bird Review (December 1996) 64(4), Hazel Scheiber

Nebraska Bird Review

This book contains 18 essays based on observations Miss Sherman made on a farm in northeastern Iowa six miles west of the Mississippi River, near McGregor. The essays were given at meetings of scientific societies (she belonged to 15) or were published in their journals, and included such titles as "Feeding Winter Birds" and "Experiments in Feeding Hummingbirds During Seven Summers." She was recognized for her knowledge of birds, and her forceful and pungent wit.

Miss Sherman was born on the Iowa farm in 1853 and died there in 1943. She was an artist and teacher for the first 20 ...
