Year: 2025

description: Purpose of the Project:The purpose of this DNP project evaluated opportunities for women living with HIV (WLWH) who are at risk for cervical cancer and who are due for screening, in an effort to improve screening rates.ProceduresConducted a chart review of 50 WLWH, evaluating patient's last Papanicolaou (Pap) test, human papillomavirus (HPV) screening, results of the Pap/HPV test, and determining whether they were due for screening. An educational toolkit was then created for the clinic designed for patients, in an effort to increase patient awareness of the need for screening. A staff survey was then conducted with four clinic staff members, assessing perceptions and beliefs about the toolkit.ResultsA total of 50 patient charts of WLWH were reviewed to determine last Pap/ HPV screening, results of these screenings, and whether patient was due for screening based on current recommended guidelines. It was found that more than half or 56% of WLWH were due for Pap/ HPV screening according to guidelines for this population. Additionally, it was found that four women refused any Pap or HPV screening. These results indicated a need and opportunity to improve screening in WLWH. Implications for PracticeThe self-collection method has broadened screening options for women by providing an alternative to traditional clinician-collected samples. This approach gives women greater choice, enhancing the likelihood of their participation in screening.
title: Manufacture of Monterey Cheese From Preacidified Milk

description: Whole milk acidified to pH 5.3 with hydrochloric acid was used for the manufacture of Monterey cheese. The milk was inoculated with one and one-half percent lactic starter and set with 12.5 ml rennet per 1000 pounds of milk. Normal washing treatments resulted in cheese with moisture in excess of 44 percent. Moisture content was brought below 44 percent by using wash water at a temperature such that the water-curd whey mixture was 35 C. The pH of cheese made by preacidification was all between 5.21 and 5.09. No acid defects were encountered. Preacidification eliminated chance of spoilage or losses caused by starter failure and abnormally sweet cheese. The lactose content of Monterey cheese made by preacidification was higher (2.9 percent) than that made by the conventional process (1.1 percent), while flavor and body and texture scores were comparable.

description: In the Landau-gauge lattice gluodynamics we find that, both in the SU(2) and SU(3) theory, a correlation of the Polyakov loop with the asymmetry of the $A^2$ gluon condensate as well as with the longitudinal propagator makes it possible to determine the critical behavior of these quantities. We discuss finite-volume corrections and reveal that they can be reduced by the use of regression analysis. We also analyze the temperature dependence of low-momenta propagators in different Polyakov-loop sectors.

description: In this paper, we discuss the incorporation of dynamic subgrid scale (SGS) models in the lattice-Boltzmann method (LBM) for large-eddy simulation (LES) of turbulent flows. The use of a dynamic procedure, which involves sampling or test-filtering of super-grid turbulence dynamics and subsequent use of scale-invariance for two levels, circumvents the need for empiricism in determining the magnitude of the model coefficient of the SGS models. We employ the multiple relaxation times (MRT) formulation of LBM with a forcing term for simulation of the grid-filtered dynamics of large-eddies. The dynamic procedure is illustrated for use with the common Smagorinsky eddy-viscosity SGS model. We also discuss proper sampling techniques or test-filters that facilitate implementation of dynamic models in the LBM. For accommodating variable resolutions, we employ locally refined grids in this framework. As examples, we consider the canonical fully developed turbulent channel flow at two different shear Reynolds numbers $Re_{*}$ of 180 and 395. The approach is able to automatically and self-consistently compute the values of the Smagorinsky coefficient, $C_S$. In particular, the computed value in the outer or bulk flow region, where turbulence is generally more isotropic, is about 0.155 (or the model coefficient $C=C_S^2=0.024$) which is in good agreement with prior data. The model coefficient is also found to become smaller and approaches towards zero near walls, reflecting the dampening of turbulent length scales near walls and the computed turbulence statistics are also in good agreement with prior data. The paper also discusses a procedure for incorporation of more general scale-similarity based SGS stress models.

Publisher: name: Utah State University
Year: 1974

description: Effect of added calcium ions on the relative milk clotting activities of porcine pepsin, Mucor miehei protease, Endothia parasitica protease, and Mucor pusillus protease was compared with that of rennin. Skimmilk, maintained at pH 6. 3 with 0.000% to 0.030% added calcium chloride, was used as a substrate. The coagulation activity of Mucor pusillus protease appeared to be most sensitive to calcium ions, followed by Mucor rniehei protease, porcine pepsin, rennin, and Endothia parasitica protease. The clotting activities of Mucor pusillus protease were also more sensitive than rennin to added calcium ions in milk samples maintained at pH values of 6.4, 6.5, and 6.6.
Mucor pusillus protease and rennin were standardized to equal activities in skimmilk maintained at pH 6.3 and 6.6 containing 0.020% added CaCl2. For skimmilk maintained at pH 6.3, Mucor pusillus protease concentrations ix that gave the same clotting times as rennin in skimmilk containing 0.000% and 0.010% added CaCl2, were 9.6% and 4.5% higher than its standardized concentration. While at pH 6.6 Mucor pusillus protease concentrations were 13.2% and 5.8% higher.

description: We examine in detail the stable reduction of Galois covers of the projective line over a complete discrete valuation field of mixed characteristic (0, p), where G has a cyclic p-Sylow subgroup of order p^n. If G is further assumed to be p-solvable (i.e., G has no nonabelian simple composition factors with order divisible by p), we obtain the following consequence: Suppose f: Y --> P^1 is a three-point G-Galois cover defined over the complex numbers. Then the nth higher ramification groups above p for the upper numbering of the (Galois closure of the) extension K/Q vanish, where K is the field of moduli of f. This extends work of Beckmann and Wewers. Additionally, we completely describe the stable model of a general three-point Z/p^n-cover, where p > 2.

title: Extractable-Emulsifying Capacity of Hand and Mechanically Deboned Mutton and Organoleptic Acceptability of Various Mutton Salami Formulations
Creators: name: Anderson, Jack Robert
Publisher: name: Utah State University
Year: 1974

description: Salt soluble extracts from mechanically deboned mutton were significantly higher (P < .01) in pH than the extracts from the hand boned mutton. An associated trend toward greater extractability, however, was not significant. Variation in emulsifying capacity between extracts from carcass parts were highly significant yet significant variation did not occur in the emulsifying capacity of hand versus mechanically deboned mutton. A new term, extractable- emulsifying capacity is presented which incorporates the extractability and emulsifying capacity of meat extracts into one value which should more accurately estimate the contribution of a meat ingredient in forming a stable sausage emulsion.
Salami, utilizing mutton, was formulated from experimental results which indicated that up to 10 percent mutton fat and 68 percent mutton lean was acceptable to panelists. Pork was preferred to beef for use in combination with mutton as determined by panel scores, however disagreement was noted between panelists. Panelists were unable to detect flavor, moisture or texture differences between the final mutton salami and a commercial beef and pork formulation. They did however prefer the appearance of the mutton salami (P < .05).

description: We address the problem of classification of contact Fano manifolds. It is conjectured that every such manifold is necessarily homogeneous. We prove that the Killing form, the Lie algebra grading and parts of the Lie bracket can be read from geometry of an arbitrary contact manifold. Minimal rational curves on contact manifolds (or contact lines) and their chains are the essential ingredients for our constructions. Along the way we collect several facts about bundles of projective lines admitting a contractible section, which might be of independent interest.

Tunable superconductivity in YBCO junctions, increasing over 20 K in transition temperature, has achieved by using electric processes. To our knowledge, this is the first observation that intrinsic property of high TC superconductors superconductivity can be adjusted as tunable functional parameters of devices. The fantastic phenomenon caused by carrier injection was discussed based on a proposed charge carrier self-trapping model and BCS theory.

description: The effects of mechanical desinewing on yield, proximate analyses and connective tissue content of pork and beef have been examined and it's influence on the appearance and palatability of cooked salami was evaluated. Mechanical desinewing removed approximately half of the connective tissue and reduced the tendency for formation of gelatin pockets in cooked salami. Yields from the desinewer ranged from 71 to 87 percent, however, cooking yield defined as cooked weight divided by uncooked weight from the desinewed salami were 6 to 7 percent higher than from the nondesinewed salami. For both the beef and pork there was no significant increase in the protein percentage. The moisture content increased by an average of 2.17 percent while the fat content decreased by an average of 2.39 percent. The taste panel evaluation indicated that tenderness and texture of desinewed salami were significantly improved over that of the nondesinewed salami.
title: Effect of Processing on Aliphatic Aldehyde Content of Turkey Meat

description: Nitrite at the level found in turkey frankfurter formulations vii did not interfere in the hydrazone test as developed by Andrews (1975). The aldehyde levels of frankfurters made principally from MD turkey meat were, on the average, twice as high as the levels in the raw meat. Aldehyde levels generally increased as the frozen storage time of the raw meat increased. There were some variations from this trend due to variation in the fat content of the raw meat. Sixty days was recommended as a maximum frozen storage time. However, because of variation in the fat content from sample to sample , assaying t he level of aldehyde in the raw meat was recommended as a more reliable method of predicting acceptability of further processed products than length of frozen storage. Aldehyde levels of less than two ppm in the raw meat and less than four ppm in the frankfurters were acceptable. The aldehyde measured by Andrews' hydrazone test was identified as formaldehyde.

description: Atom interferometry offers new perspectives for geophysics and inertial sensing. We present the industrial prototype of a new type of quantum-based instrument: a compact, transportable, differential quantum gravimeter capable of measuring simultaneously the absolute values of both gravitational acceleration, $g$, and its vertical gradient, $Γ_{zz}$. While the sensitivity to g is competitive with the best industrial gravimeters, the sensitivity on $Γ_{zz}$ reaches the limit set by quantum projection noise-leading to an unprecedented long-term stability of 0.1 E ($1E=1\times 10^{-9}s^{-2}$). This unique, dual-purpose instrument, paves the way for new applications in geophysics, civil engineering, and gravity-aided navigation, where accurate mapping of the gravitational field plays an important role.

We show that the mean perimeter < L_N > = α_N, \sqrt{T} and the mean area = β_N T for all T. The prefactors α_N and β_N, computed exactly for all N, increase very slowly (logarithmically) with increasing N. This slow growth is a consequence of extreme value statistics and has interesting implication in ecological context in estimating the home range of a herd of animals with population size N.

title: Milk Protein Analysis by Automated Ultraviolet Spectroscopy
Creators: name: Wilkinson, R. Ford
Publisher: name: Utah State University
Year: 1975

description: An automated continuous flow analysis for milk protein utilizing ultraviolet spectroscopy resulted in a correlation coefficient of 0.972 and a standard estimate of error of 0.082 percent protein when 30 samples were compared with the acid orange 12 dye binding method. Milk was solubilized in 95-105 volumes of acetic acid using the Technicon Auto Analyzer II and measured for absorbance at 274 nanometers. No deviation from the standard method due to mastitis and varying milk fat concentration was observed. A theoretical model indicated a possible standard estimate of error 0.059 percent protein due to inter- and intra-breed variation in milk protein fraction distribution. Potassium dichromate and other preservatives interfered with the results.

description: The Baldwin, Philips, & Terlevich diagram of [O III]/H$β$ vs. [N II]/H$α$ (hereafter N2-BPT) has long been used as a tool for classifying galaxies based on the dominant source of ionizing radiation. Recent observations have demonstrated that galaxies at $z\sim2$ reside offset from local galaxies in the N2-BPT space. In this paper, we conduct a series of controlled numerical experiments to understand the potential physical processes driving this offset. We model nebular line emission in a large sample of galaxies, taken from the SIMBA cosmological hydrodynamic galaxy formation simulation, using the CLOUDY photoionization code to compute the nebular line luminosities from H II regions. We find that the observed shift toward higher [O III]/H$β$ and [N II]/H$α$ values at high redshift arises from sample selection: when we consider only the most massive galaxies $M_* \sim 10^{10-11} M_\odot$, the offset naturally appears, due to their high metallicities. We predict that deeper observations that probe lower-mass galaxies will reveal galaxies that lie on a locus comparable to $z\sim 0$ observations. Even when accounting for sample selection effects, we find that there is a subtle mismatch between simulations and observations. To resolve this discrepancy, we investigate the impact of varying ionization parameters, H II region densities, gas-phase abundance patterns, and increasing radiation field hardness on N2-BPT diagrams. We find that either decreasing the ionization parameter or increasing the N/O ratio of galaxies at fixed O/H can move galaxies along a self-similar arc in N2-BPT space that is occupied by high-redshift galaxies.

title: Effect of Zinc Nutriture and Contraceptive Steroid Injection on Body Composition of Young Female Rats
Creators: name: Hahn, Sang Ai
Publisher: name: Utah State University
Year: 1975

description: Forty-nine female rats initially weighing about 95 grams were used in this experiment to determine the effect of contraceptive hormones on body composition in zinc deficient and zinc supplemented rats. Four treatment groups were: 2 ppm of dietary zinc with daily contraceptive steroid injections, or with placebo injection, and 140 ppm of dietary zinc with contraceptive steroid injection or with placebo. The daily injected steroids consisted of 0.lug of Ethynyl Estradiol and 0.lmg of Medroxyprogesterone in 0.lml of corn oil. Non-hormone treated groups received O.lml of plain corn oil. All injections were administered into the Gluteus Maximus muscle. Food intake, weight gain and serum zinc level were determined weekly. After eight weeks of experimental treatment, animals were killed by decapitation. Livers, adrenals and ovaries were removed, weighed and frozen until cholesterol determinations could be made. The remaining carcass minus the intestinal tract was autoclaved and homogenized. Carcass moisture, ash, total lipid and cholesterol ester levels were determined. Carcass zinc and calcium levels were also determined.
The results indicate that zinc deficiency causes a marked loss of appetite with a reduced growth rate and a reduced feed efficiency in the growing female rats. Serum zinc level was also reduced. Rats fed the zinc deficient diet had smaller ovaries than the controls, but their adrenal weights were unaffected. Total cholesterol content of the adrenals was, however, increased. Zinc deficient diet caused a significant elevation of carcass cholesterol esters and carcass water content, and tended to decrease liver cholesterol level. Carcass ash concentration was increased in zinc deficient rats on the basis of fat free samples.
Hormone injection caused a slight reduction in growth rate, irrespective of zinc intake, although it slightly improved appetite in the zinc deficient rats, and which caused a slight further decrease in serum zinc level. The relative weight of adrenals and ovaries were significantly decreased by hormone administration, having markedly increased total cholesterol levels. Hormone treatment tended to increase carcass cholesterol ester and liver cholesterol levels. In zinc supplemented rats, carcass total lipids was reduced, while carcass lipid was elevated in zinc deficient rats by hormone injection. Hormone treatment elevated carcass ash content with an increase in its calcium and zinc content which was statistically significant. This increase indicates the anabolic effect of contraceptive steroids on mineral in general.

description: In this review issues and methodologies pertaining to the promotion and assessment of the quality of life (QOL) experienced by people with Intellectual Disability (ID) are evaluated in light of research findings for people without ID. QOL is discussed in terms of a multidimensional and dynamic construct used as an indicator of psychological and physiological wellbeing. Objective and subjective components of QOL are reviewed, together with social and psychological factors. Various approaches to the assessment of QOL, such as the examination of people's physical location and their opportunity to acquire and apply skills for independent living are considered, together with process-centered and outcome-centered approaches to evaluation. The influence of Social Role Valorization/Normalization and processes such as deinstitutionalisation and community integration are discussed. Difficulties, such as limited receptive and expressive communication skills, encountered when eliciting the perspective of people with II) are considered. So too, difficulties inherent in the use of proxy-based respondents are discussed. It is proposed that future research should address the question of proxy-subject concurrence, including the systematic evaluation of demographic and psychological factors that may affect proxy-subject agreement concerning QOL assessment.

description: Clusters of galaxies, filled with hot magnetized plasma, are the largest bound objects in existence and an important touchstone in understanding the formation of structures in our Universe. In such clusters, thermal conduction follows field lines, so magnetic fields strongly shape the cluster's thermal history; that some have not since cooled and collapsed is a mystery. In a seemingly unrelated puzzle, recent observations of Virgo cluster spiral galaxies imply ridges of strong, coherent magnetic fields offset from their centre. Here we demonstrate, using three-dimensional magnetohydrodynamical simulations, that such ridges are easily explained by galaxies sweeping up field lines as they orbit inside the cluster. This magnetic drape is then lit up with cosmic rays from the galaxies' stars, generating coherent polarized emission at the galaxies' leading edges. This immediately presents a technique for probing local orientations and characteristic length scales of cluster magnetic fields. The first application of this technique, mapping the field of the Virgo cluster, gives a startling result: outside a central region, the magnetic field is preferentially oriented radially as predicted by the magnetothermal instability. Our results strongly suggest a mechanism for maintaining some clusters in a 'non-cooling-core' state.

title: Synthetic Spider Silk Sustainability Verification by Techno-Economic and Life Cycle Analysis
Creators: name: Edlund, Alan
Publisher: name: Utah State University
Year: 2016

description: Major ampullate spider silk represents a promising biomaterial with diverse commercial potential ranging from textiles to medical devices due to the excellent physical and thermal properties from the protein structure. Recent advancements in synthetic biology have facilitated the development of recombinant spider silk proteins from Escherichia coli (E. coli), alfalfa, and goats. This study specifically investigates the economic feasibility and environmental impact of synthetic spider silk manufacturing. Pilot scale data was used to validate an engineering process model that includes all of the required sub-processing steps for synthetic fiber manufacture: production, harvesting, purification, drying, and spinning. Modeling was constructed modularly to support assessment of alternative protein production methods (alfalfa and goats) as well as alternative down-stream processing technologies. The techno-economic analysis indicates a minimum sale price from pioneer and optimized E. coli plants at $761 kg-1 and $23 kg-1 with greenhouse gas emissions of 572 kg CO2-eq. kg-1 and 55 kg CO2-eq. kg-1, respectively. Spider silk sale price estimates from goat pioneer and optimized results are $730 kg-1 and $54 kg-1, respectively, with pioneer and optimized alfalfa plants are $207 kg-1 and $9.22 kg-1 respectively. Elevated costs and emissions from the pioneer plant can be directly tied to the high material consumption and low protein yield. Decreased production costs associated with the optimized plants include improved protein yield, process optimization, and an Nth plant assumption. Discussion focuses on the commercial potential of spider silk, the production performance requirements for commercialization, and impact of alternative technologies on the sustainability of the system.

When $p\equiv 3\pmod 8$, we prove (Theorem 2.3) that there are no solutions. For $p\not\equiv 3\pmod 8$ the treatment of the equation turns out to be a difficult task. We focus our attention to $p=5$, by reason of an article by F. Abu Muriefah, published in this journal, vol. 128 (2008), 1670-1675. Our main result concerning this special equation is Theorem 1.1, whose proof is based on results around the Diophantine equation $5x^2-4=y^n$ (integer solutions), interesting in themselves, which are exposed in Sections 3 and 4. These last results are obtained by using tools such as Linear Forms in Two Logarithms and Hypergeometric Series.

description: We investigate the chemical freeze-out in heavy-ion collisions (HICs) and the impact of the hadronic spectrum on thermal model analyses. Detailed knowledge of the hadronic spectrum is still an open question, which has phenomenological consequences on the study of HICs. By varying the number of resonances included in Hadron Resonance Gas (HRG) Model calculations, we can shed light on which particles may be produced. Furthermore, we study the influence of the number of states on the so-called two flavor freeze-out scenario, in which strange and light particles can freeze-out separately. We consider results for the chemical freeze-out parameters obtained from thermal model fits and from calculating net-particle fluctuations. We will show the effect of using one global temperature to fit all particles and alternatively, allowing particles with and without strange quarks to freeze-out separately.

title: Crustal Architecture of the Snake River Plain, Idaho, Through Geochemical Investigation of Crustal Sill and Shallow Subvolcanic Xenoliths
Creators: name: Jones, Douglas James
Publisher: name: Utah State University
Year: 2016

description: The Snake River Plain (SRP) in southern Idaho is one of the best preserved examples of continental hotspot tracks. A layered mafic intrusion has been seismically imaged in the mid-crust, however, few geochemical studies have investigated the midcrustal sill complex’s importance in the evolution of SRP magmas. This thesis investigates the geochemistry of 3 xenoliths from a mid-to-lower crustal sill complex sampled from core taken from Kimama, ID, and 3 xenoliths from a shallow sub-volcanic magma chamber beneath the SRP sampled from Sid Butte, ID. Forward modeling and partition coefficient calculations estimate the parent melt of the Sid Butte xenoliths was a Snake River Plain olivine tholeiite magma and the parent melt of the Kimama xenoliths was an evolved Craters of the Moon (COM) type S magma. Geobarometic estimates constrain the Sid Butte xenoliths origin to a shallow magma chamber at ~3.3 km and the Kimama xenoliths in a mid-to-lower crustal sill complex at ~22 km. Kimama xenoliths have average δ18O of 5.42, indicating mantle origin and little-to-no assimilation of felsic country rock. The presence of COM-type magmas in a mid-to-lower crustal sill complex that have assimilated little-to-no crustal material indicate that fractionation processes alone can produce evolved basaltic magmas in the subsurface of the SRP. This is in contrast with theories that require a substantial amount of assimilation of felsic material for the generation of evolved COM-type magmas in the SRP. This thesis not only provides a better understanding of the crustal architecture of the SRP, it provides evidence for the importance of crustal sill complexes and shallow subvolcanic magma chambers in the evolution of SRP basalts.

description: Electrolysis of water to form H2 and O2 and electrocatalytic reduction of CO2 to CO have attracted increasing attention these years. To realize a large-scale production of H2 and CO, it is critical to develop efficient and earth-abundant catalysts that could overcome the slow kinetics of the O2 evolution reaction in water splitting and selectively reduce CO2 over the competing H2 evolution reaction. This thesis describes the synthesis, characterization, and evaluation of nickel-based heterogeneous and homogeneous (molecular) electrocatalysts for water oxidation and CO2 reduction, respectively. The first project describes the Fe incorporated ultrathin Ni(OH)2 nanosheets which exhibit dramatically enhanced performance in electrocatalytic O2 evolution. The second project focus on a molecular Ni complex with a pyridyl biscarbene ligand for electrocatalytic CO2 reduction. Compared to those typical Ni complexes with cyclam-derivatized and/or -analogous tetradentate ligands, our Ni complex showed high selectivity for CO2 reduction over the competing H2 evolution reaction.

description: We prove that the essential dimension of the spinor group Spin_n grows exponentially with n; in particular, we give a precise formula for this essential dimension when n is not divisible by 4. We use this result to show that the number of 3-fold Pfister forms needed to represent the Witt class of a general quadratic form of rank n with trivial discriminant and Hasse-Witt invariant grows exponentially with n. This paper overlaps with our earlier preprint arXiv:math/0701903 . That preprint has splintered into several parts, which have since acquired a life of their own. In particular, see "Essential dimension of moduli of curves and other algebraic stacks", by the same authors, and "Some consequences of the Karpenko-Merkurjev theorem", by Meyer and Reichstein (arXiv:0811.2517).

Aesthetic control in inner city area planning : what are aesthetic guidelines for development, and what, as a result, is being built? : an exploration into aesthetic control practice, implementation and problems in Battery Point
Creators: name: Hawkes, D. L.
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of this professional project is to explore the built results of aesthetic control application, particularly in Battery Point in Hobart, and to develop an understanding of why problems, particularly historical mimicry, occur as a result of aesthetic control application. The professional project will review aesthetic control in the Battery Point Planning Scheme 1979 and include a case study of developments in Battery Point. The results from the case study will be used to develop and discuss an alternative approach for the implementation of aesthetic and design guidance for Battery Point. The initial expectation when beginning research for this professional project was that historical mimicry occurring in Battery Point can be directly attributed to aesthetic control application. The view that historical mimicry (as well as mediocre and 'bland' architecture) is being caused by aesthetic control is common throughout planning and especially architectural ideology and literature. Ultimately, this professional project aims to develop evidence that indicates aesthetic control is not the sole contributor in the development of historical mimicry. While this professional project has been researched and written to the best of the authors ability, it must be recognised that there were several limitations associated with the study and research of this professional project; - ‚Äö The subjective nature of the project topic; and ‚Äö The lack of any published material available on the project topic in an Australian and (especially) Tasmanian context. In the context of Tasmania, it is perhaps questionable to implement a planning tool such as aesthetic control that has no local examples or background theory to follow on from and determine how the tool can be best implemented into operational means, what consequences may follow and how effective the tool is likely to be in attaining the specific objectives behind its implementation.

title: Comparison of Compatibility of Streptococcus Starters in Reconstituted Nonfat Dry Milk and a Whey-Based Bacteriophage Inhibitory Medium
Creators: name: Searle, Clinton K.
Publisher: name: Utah State University
Year: 1975

description: Compatibility of mixed cultures of Streptococcus lactis and Streptococcus cremoris we e studied by the phage tracer technique in 10% nonfat dry milk and a whey-based phage inhibitory medium. Methods of membrane dialysis and differential enumeration were tried and abandoned. Dominance occurred in nonfat dry milk and in the whey-based medium during a continuous fermentation period within a pH range 6.8 to 5.2. The dominance pattern of two-strain combinations in 10% nonfat dry milk was different from that in the whey-based media. Dominance varied from one strain to another in no consistent sequence in some combinations. Dominance patterns of combinations were compared with patterns of stimulation and inhibition.
Factorization and Resummation of Higgs Boson Differential Distributions in Soft-Collinear Effective Theory

description: We derive a factorization theorem for the Higgs boson transverse momentum (p_T) and rapidity (Y) distributions at hadron colliders, using the Soft Collinear Effective Theory (SCET), for m_h>> p_T>> Λ_{QCD} where m_h denotes the Higgs mass. In addition to the factorization of the various scales involved, the perturbative physics at the p_T scale is further factorized into two collinear impact-parameter Beam Functions (iBFs) and an inverse Soft Function (iSF). These newly defined functions are of a universal nature for the study of differential distributions at hadron colliders. The additional factorization of the p_T-scale physics simplifies the implementation of higher order radiative corrections in α_s(p_T). We derive formulas for factorization in both momentum and impact parameter space and discuss the relationship between them. Large logarithms of the relevant scales in the problem are summed using the renormalization group equations of the effective theories. Power corrections to the factorization theorem in p_T/m_h and Λ_{QCD}/p_T can be systematically derived. We perform multiple consistency checks on our factorization theorem including a comparison with known fixed order QCD results. We compare the SCET factorization theorem with the Collins-Soper-Sterman approach to low-p_T resummation.

description: An experimental overview of the energy dependence of strangeness production is presented. The strange hadrons are considered a good probe to study the QCD matter created in relativistic nucleus-nucleus collisions. The heavy-ion experiments at SPS, RHIC, and LHC have recorded a wealth of data in proton-proton, proton-nucleus and nucleus-nucleus collisions at several beam energies. In this proceeding, I discuss the invariant yield and azimuthal anisotropy measurement of strange hadrons in nucleus-nucleus collisions at SPS, RHIC, and LHC.

description: We study the mathematical properties of a general model of cell division structured with several internal variables. We begin with a simpler and specific model with two variables, we solve the eigenvalue problem with strong or weak assumptions, and deduce from it the long-time convergence. The main difficulty comes from natural degeneracy of birth terms that we overcome with a regularization technique. We then extend the results to the case with several parameters and recall the link between this simplified model and the one presented in \cite{CBBP1}; an application to the non-linear problem is also given, leading to robust subpolynomial growth of the total population.

description: Decomposition of SU(2) gauge field into the monopole and monopoleless components is studied in the Maximal Abelian gauge using Monte-Carlo simulations in lattice SU(2) gluodynamics as well as in two-color QCD with both zero and nonzero quark chemical potential. The interaction potential between static charges is calculated for each component and their sum is compared with the non-Abelian static potential. A good agreement is found in the confinement phase. Implications of this result are discussed.

Habitat fragmentation and its effects on birds and grasshoppers in eucalypt remnants in the Tasmanian Midlands
Creators: name: MacDonald, MA
Publisher: name: University Of Tasmania
Year: 2023

description: In the subhumid Midlands region of Tasmania, forty-seven remnants of eucalypt woodland and dry sclerophyll forest as well as six control sites were surveyed for birds and grasshoppers, in order to examine the responses of these groups to habitat fragmentation. A wide range of characteristics of the remnants (including position in landscape, management regime and vegetation) were related to species richness, diversity and density of the two groups as well as to the distributions of individual species. Remnant size, vegetation structure and tree health all showed significant relationships with bird species richness and diversity. Small remnants with open understorey and high levels of dieback showed radically different species composition than larger ones or those with dense understorey. Where the understorey is open the noisy miner (Manorina melanocephala) is present in colonies and is able to effectively exclude almost all other species by concerted aggressive behaviour. Noisy miner colonies were associated with small remnants but were also present at the edges of larger remnants, where proximity to open country and vegetation structure both predicted their presence. Interspecific competition is considered to be the major determinant of species richness and of many species' distributions in the study area. Analysis of remnants which are not dominated by noisy miner colonies found that area and isolation were significantly correlated with species richness and diversity,. although larger remnants did not have more species at a given point. Summer migrants and nomadic species are considered to be more sensitive to habitat fragmentation as a result of the presence of noisy miner colonies in the fragmented habitat. Interspecific competition is considered to be the driving force behind avifaunal trends in the study area. Grasshopper species richness was not related to any of the variables measured, but diversity was higher in remnants in better condition, while density was higher in remnants in poor condition. Common grasshopper species responded to a range of variables. Management of remnants for conservation of avifaunal and grasshopper values is discussed. In the context of avifauna conservation, it is suggested that although larger remnants are more likely to support a healthy suite of bird species, the presence of a dense understorey in smaller remnants can improve their conservation value. Both of these options are likely to also lead to the maintenance of forest- and woodland-dwelling grasshopper species.
