Secondary metabolites from sponges (phylum Porifera)
Creators: name: Sudarma, IM
Publisher: name: University Of Tasmania
Year: 2023

description: Secondary metabolites of Tasmanian sponges (phylum Porifera) have been studied. This study involved bioassay, separation (mainly using chromatography), and structural determination (mainly using spectroscopy). Eleven terpenoids and one nucleoside, all of which have been structurally identified by spectroscopy, have been isolated from six sponges. Two new furanoditerpenes (26) and (28) which are related to ambliofuran have been isolated from Cacospongia sp. (sponge 89048). The known dendrolasin (66) and a new sesquiterpene (75) which are also analogous to ambliofuran have been isolated from sponge 89060. Sponge 88043 (Ircinia sp.1) gave a novel C\\(_{21}\\) furanoterpene (51). Compound (51) represents the first C\\(_{21}\\) furanoterpene having a 10 membered ring which has been obtained from a marine organism. The known C31 terpenoid quinol (52) and C\\(_{31}\\) terpenoid quinone (53) have been isolated from Ircinia sp.2 (sponge 90032). Variabilin (55) which was very toxic against brine shrimp and the new C\\(_{24}\\) chlorinated furanoterpene (54) were also isolated from sponge 90032. The known 2'-deoxyuridine (63) from Tedania sp.1 (sponge 88047) has a similar structure to spongouridine. This is the first time that this nucleoside has been isolated from a sponge. The known sesterterpenes (64) and furospinosulin-1 (65) were isolated from Tedania sp.2 (sponge 88049). Biogenetic considerations (\isoprene rule\") of the terpenoids under study are discussed; they are generally constructed by the conventional head-to-tail linkage of isoprenoid units. The sponges which have been investigated were selected based on results of preliminary studies using dc and brine shrimp assays."

Oxygen transfer in a fermenter
Creators: name: Liu, Ming-Shen
Publisher: name: University of British Columbia
Year: 2010

description: The effects of initial pH and the presence of solid particles on the growth rate of Thiobacillus ferrooxidans were studied in shake-flask apparatus. In addition, the effect of the ferrous iron substrate concentration on the specific growth rate of the bacteria was studied using both batch and continuous culture techniques. The effects of oxygen tension on the oxygen uptake rate of the bacteria were also examined. The critical oxygen tension and the saturation constant were found to be 6.5 and 4.5 mmHg respectively. When the oxygen tension was below 4.5 mmHg the bacteria ceased their metabolic activity. The equation that best described the oxygen uptake activity of T. ferrooxidans was found to be, [Chemical Formula]. A method for determining the saturation oxygen solubility in the culture medium is proposed. This value in 9K medium was found to be 6.68 milligrams per liter (in equilibrium with the humid air at 35C). The effect of total iron concentration on this value was also examined. A statistical curve rectification method for calculating K[sub L]a values from a dissolved oxygen concentration-time trace is proposed. Since the proposed method utilizes data directly from oxygen tension-time traces rather than from modified or limited data, it is believed to be more reliable than other techniques in use. The effects of solid pulp densities of up to 20% on K[sub L]a in an agitated tank were studied. An increase in solid pulp density was found to decrease slightly the K[sub L]a value of the system. The equation best correlating K[sub L]a values under various operational conditions is, K[sub L]a = 1.78 x 10⁻⁶(p)⁻[sup 2.84](N)[sup 2.65](V[sub s])[sup 0.57] The addition of the solid particles, although it did not affect the K[sub L] value, was found to reduce the interfacial area of the system, thus reducing the value of K[sub L]a.

title: Factors Affecting the Conditioned Reinforcing Strength of Stimuli in Differential Reinforcement of Other Behavior and Fixed-Time Schedules
Creators: name: Myers, Alexander M.
Publisher: name: Utah State University
Year: 1978

description: Two experiments were conducted in an attempt to provide a direct, response-independent test of the delay-reduction hypothesis of conditioned reinforcement. In both experiments, pigeons made observing responses, by pressing a treadle, for stimuli associated with the schedule component in effect . The consequences of an observing response were varied; an observing response produced: a) either the stimulus associated with the shorter component or the stimulus associated with the longer component depending on the schedule component in effect; b) the stimulus associated with the short component only; c) the stimulus associated with the long component only; or, d) neigher stimulus (no consequence). In Experiment I, naive pigeons were initially exposed to a mixed schedule with two differential reinforcement of other (ORO) behavior components; 10 seconds and 30 seconds (Phase One). In the second phase the same birds were exposed to an identical schedule, but the components were fixed time (FT) components (Phase Two). Reinforcement in both phases was six seconds access to food. In Experiment II, naive pigeons were exposed to both phases of Experiment I., but reinforcement density was altered. Each 10 second component was followed by 3 seconds of food and each 30 second component was followed by 9 seconds of food. In both experiments, differential observing behavior was maintained during the FT (Phase Two) procedure but not during the ORO (Phase One) procedure. In addition, equalizing reinforcement density (Experiment II) had the effect of altering the pattern of observing behavior but did not reverse or eliminate the preference shown for the stimulus associated with the shorter delay to reinforcement over the stimulus associated with the longer delay to reinforcement. It is suggested that some characteristic of the DRO procedure may have been responsible for the lack of differential observing. While the delay-reduction hypothesis of conditioned reinforcement was supported by the results of theFT procedure of both experiments, some amendments are required to account for the lack of differential observing during theDRO procedure. Reinforcement density appeared to have little effect upon observing behavior, but further research is advised concerning its effect upon observing response patterns.

description: We find a family of holographic N=1 supersymmetric RG flows on M2 branes. These flows are driven by two mass parameters from the maximally (N=8) supersymmetric theory and the infra-red theory is controlled by two fixed points, one with G_2 symmetry and the other with SU(3)xU(1) symmetry and N=2 supersymmetry. The generic flow, with unequal mass parameters, is N=1 supersymmetric but goes to the SU(3)xU(1) symmetric, N=2 supersymmetric fixed point, where the masses are equal. The only flow that goes to the G_2 symmetric point occurs when one of the mass parameters is set to zero. There is an N=1 supersymmetric flow from the G_2 symmetric point to the SU(3)xU(1) symmetric point and supergravity gives a prediction of 1/\sqrt{6} for the anomalous dimensions of the operators that drive this flow. We examine these flows from the field theory perspective but find that one is limited to qualitative results since N=1 supersymmetry in three dimensions is insufficient to protect the form and dimensions of the operators involved in the flow.

description: Newspapers are generally ascribed an important role within the community. With media attention becoming increasingly focussed on the reporting of conflict, this role can be an influential one. A great deal of research has been conducted into the relationship between the media and the broader community. Michael Gurevitch et al. have described the relationship as symbiotic - that media organisations draw on their environment both for economic survival and for the raw data needed to fulfill editorial requirements. The media is said to be a powerful influence on the formation of public opinion. According to Tod Gitlin the earliest studies have demonstrated that the media played a central role in, \consolidating and reinforcing the attitude of people.\" Newspapers have been said to \"both reflect public opinion and influence public opinion.\" Said Hertz: \"People identify closely with their newspaper and actively use it.\" It is a two-way relationship; one in which media content may influence our behaviour and our behaviour may influence the content that is offered."

title: Bait Shyness and Neophobia in Several Species of Osteichthyes: An Extension of Taste Aversion Studies to the Superclass Pices
Creators: name: Roberts, Brent W.
Publisher: name: Utah State University
Year: 1978

description: Three experiments were conducted with five species of tropical fish to investigate the phenomena of taste aversion and food neophobia. In addition, an experiment determined specifically if position in the tank could acquire conditioned aversive properties.
In Experiment 1 , four habituated fish were fed novel meat-flavored pellets on the treatment day. Six were made ill within 30, 60, or 90 minutes (2 subjects each) by intragastric administration of syrup or Epicac. The following day all were fed familiar commercial pellets. On the second day after treatment, all were offered the meat-flavored pellets. Results showed longer latencies, more tasting, and decreased consumption of novel pellets. All measures differed significantly for the treatment subjects compared to their own baseline and controls.
Experiment II demonstrated food neophobia in four in experienced fish. After habituation they were fed novel meat-flavored pellets but not made ill (day 0). On day 1 and 2 they received familiar diet and were made ill after the feeding on day 2. On day 3 they received familiar food again and no change in approach latency, testing response, or quantity consumed occurred. On day 4, they were offered the novel meat-flavored pellets which they refused. These results indicate that the fish associated the illness with the more "novel" food even though their familiar diet was temporally closer to the illness.
In Experiment III five species of naive fish were habituated to 20-gallon tanks and made ill after eating in one end and not in the other. The same food was us ed in both ends. The "illness end" could have taken on discriminitive properties and food consumption there should have decreased, as opposed to the other "safe end". The results indicated that "place" did not acquire aversive discriminitive properties. Food consumption decreased in quantity, food approach latencies increased and length of tasting bouts increased in both ends.
These experiments were the first to use these species of fish in this type of research. The results extend the phenomena of taste aversion and food neophobia. In addition, Experiment III systematically replicated the hypothesis of relevant relations between stimuli and showed that it is easier to learn certain consequences with certain cues than with others. In this case illness was quickly associated with taste but "place" was treated as irrelevant.

description: An enduring question in correlated systems concerns whether superconductivity is favoured at a quantum critical point (QCP) characterised by a divergent quasiparticle effective mass. Despite such a scenario being widely postulated in high Tc cuprates and invoked to explain non-Fermi liquid transport signatures, experimental evidence is lacking for a critical divergence under the superconducting dome. We use ultra-strong magnetic fields to measure quantum oscillations in underdoped YBa2Cu3O6+x, revealing a dramatic doping-dependent upturn in quasiparticle effective mass at a critical metal-insulator transition beneath the superconducting dome. Given the location of this QCP under a plateau in Tc in addition to a postulated QCP at optimal doping, we discuss the intriguing possibility of two intersecting superconducting subdomes, each centred at a critical Fermi surface instability.

title: Three Ordered Sets of Factors and Their Relationship to ACT Scores
Creators: name: Russo, Thomas J.
Publisher: name: Utah State University
Year: 1977

description: There has been in recent years a marked decline in college entrance examination test scores. Declines have been documented both on the Scholastic Aptitude Test (SAT) and the American College Testing Program (ACT). In turn there has been an increasing interest concerning the test score declines as well as possible sources of influence on test scores. These sources or factors seem to be functions of three main "contexts." These contexts are: (a) school-related factors, (b) student-related factors and (c) family-structure related factors. It was of interest to attempt to explain the relative association of each variable to composite ACT scores and of each "context" to composite ACT scores. In turn, it was of interest to attempt to assess the extent to which combinations of two, or all three sets of variables aid in explaining the variance on composite ACT scores.
The sample population consisted of entering college freshmen at Utah State University for the fall quarter of 1976. All Ss were
from one of the six major feeder high schools to Utah State University. Information was gathered through the use of a questionnaire distributed at freshmen registration and by mail. Other sources of information included school principals and official student ACT transcripts and school records. Using composite ACT scores as the dependent variable both stepwise and hierarchical multiple regression analyses were done.
As a result of stepwise multiple regression using all ten factors, it was found that academic course taking had the greatest partial regression coefficient. Next -in predictive power was the level of educational aspiration of the student. Size of school entered the prediction equation on Step 3 and was negatively associated with composite ACT scores.
Student-related factors helped to explain 38 percent of the total variance on composite ACT scores and as such comprises the most significant "context" of association. More modest support has been demonstrated for school-related factors. Family-structure factors do not appear significantly related to composite ACT scores. Recommendations were made for a larger sample sjze from a more diverse geographic region.

title: Effects of Variable and Changing Environments on Demography: Inferences from a Lesser Snow Goose Colony
Creators: name: Iles, David T.
Publisher: name: Utah State University
Year: 2017

description: Anthropogenic pressures have caused changes in both the mean and variance of environmental conditions, with associated effects on the demography of natural populations. The demographic effects of environmental change can manifest through direct (i.e., physiological) or indirect pathways (i.e., through shifts in species interactions). For many populations, environmental change will affect multiple life cycle stages simultaneously, thereby altering vital rate correlation structures with potentially important impacts on evolutionary fitness. The effects of environmental change will also often be habitat-specific, particularly when species interactions modify demographic sensitivity to climate. As a result, the effects of climate change are likely to vary across a species range, with important implications for range expansion and population viability.
In chapter 2, I examine the effects of joint vital rate responses to environmental drivers on the evolution of life histories in variable environments. I show that vital rate covariation, generated when multiple vital rates respond to a shared environmental driver, can fundamentally alter evolutionary selection pressures. Negative vital rate covariation promotes the evolution of demographic lability (stronger demographic responsiveness), while positive covariation promotes buffering (weaker demographic responsiveness), altering the range of life histories over which the evolution of buffered and labile vital rates are a predicted evolutionary outcome. By identifying the life histories for which selection pressures are most sensitive to environmentally-driven vital rate covariation, this study provides a richer understanding of both life history evolution and the capacity of species to cope with ongoing changes to contemporary environments.
In chapter 3, I use a long-term study of lesser snow geese to test the hypothesis that demographic and developmental responses to climate will be weakest in habitats where resource diversity is greatest. I find support for this hypothesis, and my results indicate that gosling demography is much more responsive to climate in recently colonized, freshwater habitats where landscape diversity and gosling diet diversity is low. These results underscore the potential importance of accounting for biotic interactions when predicting spatio-temporal responses to climate.
In chapter 4, I quantify the consequences of observed climate change for lesser snow goose population dynamics across habitats. I find that climate change increases population growth in all habitats, but that such increases are disproportionately large in novel inland freshwater habitats. These results suggest that in a warmer and more variable climate, the breeding range and population growth of lesser snow geese is likely to increase, counteracting current management efforts to reduce overabundant populations.

We perform the generalization of Abel transform tomography approach for the case of gluons. We also discuss the skewness effect in the framework of the dual parametrization. We strongly suggest to employ the fitting strategies based on the dual parametrization to extract the information on GPDs from the experimental data.

Potential of spent sulfite liquor as raw material for production of vitamin B12 by certain species of lactobacillus, propionibacteria, and streptomyces
Creators: name: Truong, Thieu Long
Publisher: name: University of British Columbia
Year: 2010

description: Spent sulfite liquor is suitable for growth of Propionibacteria freudenreichii, Propionibacteria shermanii, and Lactobacillus plantarium but not for Streptomyces griseus and Streptomyces olivaceus. L. plantarium and P. freudenreichii together, in fermentations of two stages or of one stage with mixed culture, are poor in serving the ultimate goal of producing vitamin B12 in substantial quantity. P. shermanii is not as good a producer of vitamin B12 from SSL as P. freudenreichii alone. Fermentations of SSL with P. freudenreichii show a net increase in market value of the broth. They should be done in two stages, the first anaerobic and the second aerobic. The optimum requirements are 5g/l of yeast extract as essential nitrogen source and 1ppm of cobalt ions as precursor. The optimum yield in vitamin B12 is 1.5mg/l, accompanied by the production of 0.14 moles/1 of volatile acids. 5,6-dimethyl benzimidazole is found to be beneficial to the yields of cells, of vitamin B12 and of volatile acids. Fish plant effluent is not a suitable replacement for yeast extract. The reduction of the polluting potential of SSL, accomplished by these fermentations, is only about 14% of the total chemical oxygen demand. This reduction is due to the removal of about 70% of the reducing sugars, transformed to cells and volatile acids. These sugars originally contribute a polluting potential of 20% of the total COD to SSL.
title: Molecular and Physiological Mechanisms of Toxin Resistance in Toad-Eating Snakes

description: Many plants and animals are defended by toxic compounds, and circumvention of those defenses often has involved the evolution of elaborate mechanisms for tolerance or resistance of the toxins. Toads synthesize potent cardiotonic steroids known as bufadienolides (BDs) from cholesterol and store those toxins in high concentrations in their cutaneous glands. Those toxins protect toads from the majority of predators, including most snakes that readily consume other species of frogs. BDs exert their effect by inhibiting ion transport by the Na+/K+-ATPase (NKA). This ubiquitous transmembrane enzyme consists of a catalytic alpha-subunit, which carries out the enzyme's functions, and a glycoprotein beta-subunit, which provides structural stability. Inhibition of the NKA causes highly elevated intracellular Ca2+ levels and results in often lethal increased cardiac contraction strength. Molecular resistance to bufadienolides in snakes is conferred by mutations in the alpha-subunit of the Na+/K+-ATPase. I have found that these mutations are more prevalent in snakes than previously suggested, and that many genetically resistant species do not feed on toads. This suggests that possession of the mutations alone does not carry substantial negative consequences, and that feeding on toads may have been an ancestral habit in some groups of snakes. I have further found evidence of tissue-specific variation in resistance to bufadienolides, and gene expression investigations revealed that the bufadienolide resistance-conferring mutations are not expressed equally among different organs. Variation in resistance among different tissues indicates that possession of the mutations does not protect all cells equally. Finally, by testing the physiological responses of resistant snakes to exposure to cardiotonic steroid, I have found that feeding on toads incurs negative consequences and that toad-specialized resistant snakes respond differently from nontoad-specialized resistant snakes. The presence of physiological consequences of toxin exposure may explain why feeding on toads has been lost in some lineages of snakes that retain resistance-conferring mutations. In summary, these findings indicate that genetic resistance of the Na+/K+-ATPase is necessary in order for snakes to survive acute toxicity of bufadienolides, but it is not sufficient to explain fully the physiological mechanisms involved in dealing with chronic exposure to the toxins.

description: In this paper, we study the effects of introducing contrarians in a model of Opinion Dynamics where the agents have internal continuous opinions, but exchange information only about a binary choice that is a function of their continuous opinion, the CODA model. We observe that the hung election scenario still exists here, but it is weaker and it shouldn't be expected in every election. Finally, we also show that the introduction of contrarians make the tendency towards extremism of the original model weaker, indicating that the existence of agents that prefer to disagree might be an important aspect and help society to diminish extremist opinions.

The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.brThe project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.brThe first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.
title: Determining Natural Frequencies Using Embedded and Placed Sensors under Ambient and Shaker Excitation

description: Dynamic monitoring of structures is a method of detecting changes and damage to the structure. Vibration based monitoring has been used to detect damage in rotating machinery and is gaining popularity in the field of Structural Health Monitoring (SHM). Monitoring involves detecting changes in natural frequencies and changes in mode shapes. These changes reflect changes to properties of the bridge which can indicate damage.
The Nibley Bridge is a single span bridge comprised of ten deck bulb girders. The bridge spans 25.91m (85 ft.) and includes two lanes, sidewalks on both sides, and a small median. The Nibley Bridge was constructed with monitoring in mind. A dynamic monitoring system was planned to detect frequencies for long term monitoring. Initial monitoring of the embedded accelerometers was ineffective, so additional testing was required. An impact test was done with additional sensors to calibrate the embedded sensors. To further define the natural frequencies and mode shapes of the bridge, two shaker tests were also performed.
The embedded sensors were noted as having a large noise range. Also, they required a specific data logger to detect meaningful data. Recommendations for the use of the embedded accelerometers were determined and defined. The additional tests were able to assist in calibrating the accelerometers, as well as defining the natural frequencies and mode shapes of the structure. Natural frequencies were defined for each test and the changing condition of the bridge between those tests. The addition of asphalt occurred between two tests and a change of approximately 20° C between the other two tests. Though there is not much information to form a correlation, the detected changes define the dynamic aspects of the bridge.
Lastly, mode shapes were determined and a Modal Assurance Criterion (MAC)analysis was done to correlate the measured and analytical mode shapes. This model helped to indicate which parameters effect the mode shapes of the structure. Comparison between these parameters and changes between them help to indicate the predicted behavior of the structure under different circumstances. Though these tests do not define all of the dynamic properties of the bridge, they do provide a general baseline of values that can be expected for future tests of the structure.
