description: We suggest an approach to use memristors (resistors with memory) in programmable analog circuits. Our idea consists in a circuit design in which low voltages are applied to memristors during their operation as analog circuit elements and high voltages are used to program the memristor's states. This way, as it was demonstrated in recent experiments, the state of memristors does not essentially change during analog mode operation. As an example of our approach, we have built several programmable analog circuits demonstrating memristor-based programming of threshold, gain and frequency.
title: Morphological Development in Relation to Cold Hardiness of Dormant Peach Fruit Buds
Creators: name: Seeley, Schuyler Dranna
Publisher: name: Utah State University
Year: 1968

description: The morphological development of Elberta peach fruit buds was studied in relation to their cold hardiness. Morphological development of peach fruit buds was observed beginning with bud differentiation in mid-summer. Flower initiation was essentially complete by September. Growth was slow in the winter months but increased rapidly as anthesis approached. Photomicrographs were taken to substantiate the discussion . Cold hardiness determinations were made from December until anthesis in April. The hardiness level was greatest during December and remained at a relatively high level until rest ended. Hardiness decreased thereafter. Major losses of hardiness occurred just prior to anthesis.
Development of pasture growth models for grassland fire danger risk assessment
Creators: name: Daily, HG

Year: 2023

description: Assessment of grassland curing (the proportion of dead to total material in a grassland fuel complex) is of great importance to fire authorities, which use it as an input into fire behaviour models and to calculate the Grassland Fire Danger Index. Grass curing assessments require improved accuracy to better define fire danger periods and improve management of resources, particularly around the use of prescribed burns. This project investigated the suitability of existing plant growth models in three agricultural decision support tools (DST), namely, APSIM, GrassGro‚Äövë¬¢ and the SGS Pasture Model, to estimate curing in a range of grass growth types. Simulations using appropriate DST were developed for phalaris (perennial introduced), annual ryegrass (annual introduced), or perennial native pastures, and for wheat (annual cereal) crops. The DST were not able to produce reliable curing estimates compared to the field assessments of curing, in part because the current state of knowledge on the senescence stage of leaf development has not been easy to incorporate into DST algorithms. A Leaf Curing Model was developed for the same species grown under glasshouse conditions. The Leaf Curing Model was based on the proportion of cured leaf material over time but was not suitable for estimating curing in the field because it lacked responsiveness to plant leaf development and assumed irreversibility of curing. This thesis provides a comprehensive study of leaf turnover rates determined from leaf measurements recorded on glasshouse-grown plants, over the entire lifecycle. The relationship between leaf appearance rate (LAR), leaf elongation rate (LER), leaf life span (LLS), leaf length, and leaf senescence rate (LSR) with leaf position on the plants were determined. The effect of terminal water stress imposed early, mid-way, or late in spring in glasshouse-grown plants was contrasted to LSR and leaf length of field-grown plants. In most conditions, water stress increased LSR but did not affect leaf length. The relationship between the leaf rates and leaf position was maintained under conditions of water stress. Finally, a Bayesian model was developed from the full range of leaf turnover characteristics calculated from glasshouse-grown plants under optimal conditions. The Bayesian model predicted green leaf biomass and percentage of dead material (curing percentage) over thermal time. A derivative of the curing output of the Bayesian model was successfully validated against field methods, and would provide a higher level of accuracy of grass curing prediction than the pasture growth models currently incorporated into commonly-available DST.

description: In this work, natural rubber (NR) was masticated using an internal mixer to fit the requirements of reactive blending with polylactide and characterized by size exclusion chromatography (SEC), Fourier-transform infrared (FT-IR) spectroscopy and dynamic rheology measurements. Subsequently, the effect of elevated temperatures (25 °C, 80 °C, and 170 °C) on the electron beam (EB) induced crosslinking and degradation of masticated natural rubber (mNR) in a nitrogen atmosphere without adding crosslinking agents has been investigated. The sol gel investigation showed that the gel dose of mNR slightly increased with increasing irradiation temperature, which is also confirmed by the swelling test. The chain scission to crosslinking ratio (Gs/Gx) was found to be less than 1 for irradiated mNR at 25 °C and 80 °C, suggesting a dominating crosslinking behavior of mNR. However, a significant increase of Gs/Gx ratio (~1.12) was observed for mNR irradiated at 170 °C due to the enhanced thermal degradation behavior at high temperature. A remarkably improved elasticity (higher complex viscosity, higher storage modulus, and longer relaxation time) for EB modified mNR was demonstrated by dynamic rheological analysis. Particularly, the samples modified at higher temperatures represented more pronounced elasticity behavior which resulted from the higher number of branches and/or the longer branched chains.

description: We investigate the Q-ball formation in the thermal logarithmic potential by means of the lattice simulation, and reconfirm qualitatively the relation between Q-ball charge and the amplitude of the Affleck-Dine field at the onset of its oscillation. We find time dependence of some properties of the Q ball, such as its size and the field value at its center. Since the thermal logarithmic potential decreases as the temperature falls down, the gravity-mediation potential will affect the properties of the Q ball. Even in the case when the gravity-mediation potential alone does not allow Q-ball solution, we find the transformation from the thick-wall type of the Q ball to the thin-wall type, contrary to the naive expectation that the Q balls will be destroyed immediately when the gravity-mediation potential becomes dominant at the center of the Q ball.

title: A Formula to Express Evapotranspiration as a Function of Soil Moisture and Evaporative Demands of the Atmosphere
Creators: name: Norero, Aldo L.
Publisher: name: Utah State University
Year: 1969

description: A mathematical expression was developed and tested which describes the relation between evapotranspiration and soil moisture. A general premise of this mathematical model is that the evapotranspiration-soil moisture relationship is determined by interaction of climatic, soil and plant factors. The basic model is
dETa/dYs = -ke[1-(ETa/ETmx)]
in which ETa is the actual evapotranspiration, Ys is the total soil water potential, k is a proportionality coefficient , E is the soil moisture extraction capacity of the atmosphere , and ETmx is the evapotranspiration that would occur from a particular crop-soil unit when soil moisture was not limiting. From this model the following expression was derived:
ETa = (1/1+(Ys/Ys’)^[2.56/log (Ymi/Ymx)])g E0
where Ymx', Ys', Ymi are the soil potentials at which ETa is equal to 95%, 50% and 5% of ETmx' respectively; E 0 is the evaporation from a free water surface and expressed the evaporative demands of the atmosphere. The term g is a proportionality coefficient equal to ETmx/E0.
A second formula was developed that expresses the same relationship in terms of soil water content, and was derived from the former by assuming a hyperbolic relationship between soil water potential and water content. These formulas, as well as various other models which are described in the literature, were tested using experimental data covering a wide range of climatic, soil and plant variables.
It was concluded that: (a) Most models advocated in the literature are only adequate to describe the relation between evapotranspiration and soil moisture under particular climatic , soil and plant conditions. (b) The formulas derived from the proposed model provide a good fit for the evapotranspiration-soil moisture relationship under widely different circumstances. If proper values are chosen for the coefficients, these formulas yield relations that are similar to several of the models taken from the literature. Consequently, the proposed mathematical expression appears to be a general model of the manner in which plants use soil water under different vegetative and environmental conditions. (c) It seems possible to predict in a comparative way the pattern of soil water utilization in a soil-plant-atmosphere system . This may be done from a knowledge of the relations between the coefficients of the formulas and climatic, soil and plant factors influencing evapotranspiration.

description: We compute the multipartite entanglement measures such as the global entanglement of various one- and two-dimensional quantum systems to probe the quantum criticality based on the matrix and tensor product states (MPSs/TPSs). We use infinite time-evolving block decimation (iTEBD) method to find the ground states numerically in the form of MPSs/TPSs, and then evaluate their entanglement measures by the method of tensor renormalization group (TRG). We find these entanglement measures can characterize the quantum phase transitions by their derivative discontinuity right at the critical points in all models considered here. We also comment on the scaling behaviors of the entanglement measures by the ideas of quantum state renormalization group transformations.

title: The Effects of DCPA and Trifluralin on Northern Root-Knot Nematode (Meloidogyne hapla Chitwood) Infection of Selected Vegetables
Creators: name: Romney, Rulon Kent
Publisher: name: Utah State University
Year: 1972

description: The interaction of herbicides and Northern root-knot nematodes (Meloidogyne hapla Chitwood) on onions and beans was studied in the greenhouse. Seeds of onions (Allium cepa L.) were planted in soil treated with defferent levels of dimethyl 2,3,5,6-tetrachloroterephthalate (DCPA). Seeds of beans (Phaseolus vulgaris L.) were planted in soil treated with different levels of DCPA or α, α, α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin). Seedlings were inoculated with root-knot nematode larvae after 2 week's growth.
DCPA reduced root and shoot growth on onions but did not significantly affect bean growth. Trifluralin significantly reduced root and shoot growth of beans. Growth reduction was directly related to the concentration of DCPA or trifluralin. Anatomical studies on onion roots indicated that the epidermal cells were seriously affected by DCPA treatment. They were greatly misshapen, overlapped, and in various stages of apparent dissolution or collapse. Symptoms were more severe under higher concentrations. Macroscopic examination of roots treated with DCPA or trifluralin showed soil particles strongly adhered to root tissue. DCPA-treated and non-treated nematode larvae were equally pathogenic on onions. Both DCPA and trifluralin significantly reduced the number of nematode galls formed on beans and onions grown in treated soil.

description: We analyse the entanglement dynamics in a nonlinear Kerr-like coupler interacting with external environment. Whenever the reservoir is in a thermal vacuum state the entanglement (measured by concurrence for a two-qubit system) exhibits regular oscillations of decreasing amplitude. In contrast, for thermal reservoirs we can observe dark periods in concurrence oscillations (which can be called a "sudden death" of the entanglement) and the entanglement rebuild (which can be named the "sudden birth" of entanglement). We show that these features can be observed when we deal with 2-qubit system as well as $2\otimes 3$ system.

title: An Intensive Edaphological Characterization of The Soils of Malambito Experimental Station And Its Implications in Future Agricultural Research
Creators: name: Rubink, William L.
Publisher: name: Utah State University
Year: 1973

description: Malambito Experiment Station, in the Atlántico III project area, Department of Atlántico, Colombia, had almost no quantitative edaphological data on which to base agricultural research. Unexplainably low general yields as well as problem areas of deficient plant growth only confounded the results of field plot experiments. Intensive soil sampling and subsequent measurements of pH, ECe of the saturation extract, and the four major cations disproved the previous suggestions that the crop growth problems were related to saline, sodic, or degraded soil conditions. The Ca/Mg+K+Na ratio, although significant when correlated with plant height, was sufficient explanation for only a small portion of Malambito problem. The heavy soil texture (50 percent clay) was also shown to be of minor importance in the overall problem. Although no difinitive answer was given to explain the variations in plant growth, a basis for further research was provided, including estimates of soluble plus exchangeable cations and their field variability, pH, organic carbon, ECe and CEC. Future studies in the areas of micronutrient deficiencies and toxicities and possible resistant crops were advocated.
Recent research based on the results of this thesis has now implicated heavy metal toxicity as a probably cause for the growth deficiencies and low yields at Malambito.

Year: 1973

description: Proton-neutron electron-positron pair production cross sections are calculated in the framework of the pseudoscalar one-pion exchange model in a fully relativistic manner.
A computer program has been developed to evaluate invariants and Dirac traces for a given data point.
The sections for symmetric coplanar events for laboratory kinetic energies of 10 to 250 MeV were calculated for pair angles of 20° to 120°.
Frequency distributions were also calculated, at a laboratory energy of 200 MeV, using a random number generator to select data points. The frequency distributions are illustrated by curves.
It was noted that the inclusion of heavier bosons will not significantly improve the results at laboratory energies less than 200 MeV.

description: Overlap with the separable state is introduced in this paper for the purpose of characterizing the overall correlation in many-body systems. This definition has clear geometric and physical meaning, and moreover can be considered as the generalization of the concept-Anderson Orthogonality Catastrophe. As an exemplification, it is used to mark the phase transition in the Dicke model for zero and finite temperature. And our discussion shows that it can faithfully reflect the phase transition properties of this model whether for zero or finite temperature. Furthermore the overlap for ground state also indicates the appearance of multipartite entanglement in Dicke model.

Creators: name: Roundy, Theron E.
Publisher: name: Utah State University
Year: 1972

description: A pollen-restorer sugarbeet inbred, developed by four generations of selection of highly fertile plants from a CMS X table beet cross, was studied to determine if a change from sterile to fertile cytoplasm had occurred. Data showed that the fertility expressed by the restorer inbred was the result of genetic factors and not cytoplasmic reversion. Linkage tests with the Rf gene showed independence of the YRB group, m and vi4. A yellow-loaf mutant was inherited as a simple recessive factor. A partial pollen-restorer character, found in the yellow-leaf material, was inherited as a single dominant gene. The restorer factor was independent of yl and m, while the yl gene showed independence of m and B.
title: Understanding Utah's Native Plant Market: Coordinating Public and Private Interest
Creators: name: Hooper, Virginia Harding
Publisher: name: Utah State University
Year: 2003

description: Changes in Lone Peak Conservation Nursery customer profiles cause state nursery leaders to question what their products are being used for and how trends in native plant use are changing the market for Utah native plants. The Utah native plant market is changing as interest in native plants is expanding to meet new conservation objectives, oftentimes in urban settings. This newer demand for native plants appears to be motivated by current changes in urban conservation behavior, continued population growth in the arid West, scarcity of water resources, the increasing appreciation for indigenous plant aesthetics, and concern for bio-diversity. A survey of2001 American Society of Landscape Architecture (ASLA) Utah Chapter members sponsored by Lone Peak Conservation Nursery, a state-mandated nursery for the supply of conservation plants to Utah, conveys landscape professionals' philosophical base for native plant choice, experience of native plant use, information needs, desired products and services, and general perception of native plant market and demand in Utah. Landscape architects at the forefront of these trends and the profession have the opportunity to be even more actively engaged in integrating native plant use across the wild land to urban landscape spectrum while collaborating with other industry leaders.
Authors report on the significant findings from the Lone Peak ConservationNursery Native Plant Study to explain the complexity of native plant supply and demand in changing Utah markets. Increase in urban water conservation and aesthetic use of native plants and seeming instability in traditional restoration markets force local growers to face challenging decisions about plant production and business strategies. Business-driven decisions of suppliers may affect the availability of source-identified native plant products, and raises the question, "How native is native?" Current dilemmas in the Utah native plant market are identified as market pressures tend to generalize an ecologically specialized natural resource product. Continued research and industry collaboration is needed to better connect supply and demand to better balance the needs of private and public sector market actors sharing native plant resources.

Year: 1968

description: During the past four years it has been easy to see that there has been no art direction in the visual communications of Utah State University. Recently the university has become aware of the importance of a good public relations program and has taken steps in that direction. Very little thought has been given to the visual design of these public relations though. Advertising gives information, plants ideas, and provokes interest in a service and company, but it must be designed well to be noticed. Corporate image includes many things, but I shall only deal with the visual or graphic design part. This is the corporate design.
Product analysis, consumer research, and market analysis are investigated in connection with Utah State University. What makes a good advertisement is analyzed. The media most appropriate for the university is pointed out. Facts are illustrated with photographs of hypothetical advertising pieces. Each advertising piece is analyzed to show how it contributes to the complete corporate design of the university.
A high level of quality in corporate design cannot be reached unless the university employs the talents of a professional designer. The conclusion of this thesis points out the three courses that could be taken to acquire such a person.
The photography of street art as a representation of place
Creators: name: Thomashow, JE
Publisher: name: University Of Tasmania
Year: 2023

description: This research project explores how the photography of street art can contribute to the understanding of place. This argument is supported through an examination of techniques and concepts utilized by a range of photographers who have practiced social documentation. The research aims to demonstrate how the photography of street art can reflect social, cultural, and natural identities that are unique to specific environments. The background to this project is located in the tradition of social documentary in the work of mid 20th century photographers such as Walker Evans, Robert Frank, and Manuel Alvarez Bravo. The exegesis explores these artists' abilities to capture the vernacular elements that characterize specific locations. The exegesis discusses the arrangement of elements within individual photographs, as well as the arrangement of the photographs in series, and specifically how these strategies provide a social and political commentary. The project is further contextualized by a range of contemporary color photographers including Joel Sternfeld, Steven Shore, Jeff Laio, and Jeff Whetstone, demonstrating the potential for color to contribute to an exploration of place within social documentary photography. The result of the research is a collection of photographs that describe differences in a range of social landscapes by comparing styles and techniques in street art from three different countries: Australia, South Africa, and the United States. The thesis exhibition consists of a series of large scale photographic prints that depict street artworks in their surrounding context, including people and natural or built environments. In these photographs, street art is the dominant form of vernacular expression. It embodies the visual characteristics of environments undergoing pronounced change. These photographs form a narrative concerned with the social, political, and natural identities of a place.

description: A series of new flame retardants (FR) based on dibenzo[d,f][1,3,2]dioxaphosphepine 6-oxide (BPPO) incorporating acrylates and benzoquinone were developed previously. In this study, we examine the fire behavior of the new flame retardants in polyisocyanurate (PIR) foams. The foam characteristics, thermal decomposition, and fire behavior are investigated. The fire properties of the foams containing BPPO-based derivatives were found to depend on the chemical structure of the substituents. We also compare our results to state-of-the-art non-halogenated FR such as triphenylphosphate and chemically similar phosphinate, i.e. 9,10-dihydro-9-oxa-10- phosphaphenanthrene-10-oxide (DOPO), based derivatives to discuss the role of the phosphorus oxidation state.

description: The proximity-effect, whereby materials in contact appropriate each others electronic-properties, is widely used to induce correlated states, such as superconductivity or magnetism, at heterostructure interfaces. Thus far however, demonstrating the existence of proximity-induced charge-density-waves (PI-CDW) proved challenging. This is due to competing effects, such as screening or co-tunneling into the parent material, that obscured its presence. Here we report the observation of a PI-CDW in a graphene layer contacted by a 1T-TaS2 substrate. Using scanning tunneling microscopy (STM) and spectroscopy (STS) together with theoretical-modeling, we show that the coexistence of a CDW with a Mott gap in 1T-TaS2 coupled with the Dirac-dispersion of electrons in graphene, makes it possible to unambiguously demonstrate the PI-CDW by ruling out alternative interpretations. Furthermore, we find that the PI-CDW is accompanied by a reduction of the Mott gap in 1T-TaS2 and show that the mechanism underlying the PI-CDW is well-described by short-range exchange-interactions that are distinctly different from previously observed proximity effects.

Red River architecture, 1812-1870
Creators: name: Wade, Jill
Publisher: name: University of British Columbia
Year: 2011

description: The thesis is concerned with the architecture of the Red River Settlement between 1812 when the Selkirk settlers first arrived at Red River and 1870 when the province of Manitoba entered Confederation. Its objectives are (i) to establish the stylistic influences on Red River architecture and (ii) to examine the place of that architecture in the Red River environment. Research consisted of field work and examination of written and pictorial material. Almost all the extant buildings were visited, photographed, and, in some instances, measured. Primary and secondary source materials relating to the history and the architectural history of the Red River Settlement were used, and original and reproduced pictorial material was examined. It has been concluded that the common log construction in the Red River Settlement was the Hudson's Bay style, also known as the Red River frame, the "poteaux sur sole", and "pièce sur pièce". The Hudson's Bay style was used in the trade of the North West Company and later the Hudson's Bay Company, and it was adopted by the first settlers at Red River from the fur traders who preceded them in the area. It was used in houses and churches, as well as outbuildings, stores, and schools. It became outmoded after 1870 when different log construction methods, architectural styles, and building materials were introduced by settlers from Ontario. It has also been concluded that the large stone and wood houses of the Red River Settlement were built in an architectural style associated with the Hudson's Bay Company. The style originated in the Anglo-Norman buildings of French Canada and in the laird's house of eighteenth century Scotland. At Red River, it was adopted for the homes of the natural aristocracy of the settlement from the fur trade buildings which were built at Upper Fort Garry and Lower Fort Garry after 1830. Church architecture in Red River was influenced by the contemporary architecture of French Canada and England. The Roman Catholic churches were built in the style of Thomas Baillairge, whereas the Anglican churches integrated Gothic Revival detail with the box-like form common to Red River buildings. The Presbyterian churches tended to follow the style of the Anglican churches with some minor adaptations. The primary influences on Red River architecture were thus British and French Canadian in origin. The Red River Settlement was essentially a riverside village. Its buildings stood in a row along the banks of the rivers. The linear arrangement was relieved by the winding rivers and punctuated by the different types of architecture, by the location of important buildings on the bends of the rivers, and by the concentration of buildings in the forts, missions and farm-yards.

description: Controlling the bandstructure of Dirac materials is of wide interest in current research but has remained an outstanding challenge for systems such as monolayer graphene. In contrast, Bernal bilayer graphene (BLG) offers a highly flexible platform for tuning the bandstructure, featuring two distinct regimes. In one regime, which is well established and widely used, a tunable bandgap is induced by a large enough transverse displacement field. Another is a gapless metallic band occurring near charge neutrality and at not too strong fields, featuring rich 'fine structure' consisting of four linearly-dispersing Dirac cones with opposite chiralities in each valley and van Hove singularities. Even though BLG was extensively studied experimentally in the last two decades, the evidence of this exotic bandstructure is still elusive, likely due to insufficient energy resolution. Here, rather than probing the bandstructure by direct spectroscopy, we use Landau levels as markers of the energy dispersion and carefully analyze the Landau level spectrum in a regime where the cyclotron orbits of electrons or holes in momentum space are small enough to resolve the distinct mini Dirac cones. We identify the presence of four distinct Dirac cones and map out complex topological transitions induced by electric displacement field. These findings introduce a valuable addition to the toolkit for graphene electronics.
Achieving and maintaining prison officer-prisoner relationships: Tasmanian perspectives from a time of culture change

description: Prison officer-prisoner relationships are at the heart of prison life. This thesis seeks to understand what, from the perspective of the prison officer, is an effective officer-prisoner relationship. Secondly it asks how a prison that overtly places the prison officer-prisoner relationship as the central mechanism through which organisational and operational policies are understood and implemented might differ from a more traditional way of managing the prison. Effective staff-inmate relationships enable staff to maintain a peaceful prison environment in which staff and inmates are able to meet their needs. They are characterised by mutual respect, trust, humanity, good communication and a clear understanding of the correctional officer role. Effective relationships are important because they contribute to a safe prison environment and greater inmate compliance. They are also necessary before officers can work with inmates to address their problems and reasons why they are in prison. The basis for effective relationships seems to lie in the prison officers' attitudes and beliefs about inmates. The prison officers interviewed in this study view the inmates as autonomous human beings who have individual differences and who are entitled to humane treatment. They hold values about relationships that include notions such as respect, honesty, empathy, compassion, humanity, fairness and a belief that inmates can change. Importantly the officers are able to balance the security and welfare dimensions of their role. A prison that places the prison officer-prisoner relationship at the centre of prison management would respond to prisoner misconduct and disorder by first examining the status of prison officer-prisoner relationships and monitoring efforts to improve their effectiveness. It would endeavour to broaden the prison's imaginative circumference to incorporate a rich correctional landscape that extends beyond simply warehousing criminals, to encompass a role that is concerned with the human rights and dignity of the prisoner, a belief in their capacity to grow and a desire to play an active part in this process.
Disciplinary rhetorics and fractal orderings : a study of sociologies of knowledge and of presidential addresses to the American Sociological Society/Association
Creators: name: White, R

description: This thesis is a demonstration of the practical achievement of sociological knowledge in the absence of epistemological foundations. Its argument is derived from, and applied to, the disciplinary rhetorics in sociologies of knowledge and presidential addresses to the American Sociological Society Association. The formal sociologies of knowledge are shown to be representations of discipline, and the addresses, delivered by formal representatives of the discipline, to be 'folk' sociologies of knowledge. 'Discipline' epitomises the location of sociology in the processes studied within it, and of the sociology of knowledge within sociology at large. As subsumed in 'Mannheim's paradox', the sub-/metadiscipline has always been characterised by such epistemological difficulties as circularity, infinite regress, or the apparent self-negation of relativised knowledge. These difficulties, which are also characteristic of the discipline at large, are clarified in Latour's account of the modern as a separation of epistemological from political senses of representation. Sociologists of knowledge have resolved 'Mannheim's paradox' by two recurrent forms of representation; or modes of ordering. Either they relate knowledge to its context in binary terms (which then either axiomatically or tacitly favours the epistemological over the political), or they avoid this preemption through trinary orderings. The deferral of analytical closure in trinitarianism is used in a description of disciplinary knowledge as a 'fractal ordering' of 'disciplinarity', 'disciplining' and 'discipline', where 'fractal' denotes a jagged self-similarity across different scales of study. In their little-studied addresses to the ASS/ A, the presidents are rhetorically required to discuss disciplinary knowledge but are rhetorically constrained from doing so with formal rigour. The addresses are then a practical enactment of 'Mannheim' s paradox', and the presidents are folk sociologists of knowledge. Folk and formal disciplinary rhetorics are linked through equation of the 'discipline' from the sociologies of knowledge with 'the discipline' of American sociology, through quantitative matching of 'real factors'from the presidents' organisational characteristics with 'ideal factors' from their addresses, and through use in the addresses of 'disciplinarity', 'disciplining' and 'discipline'. In demonstrating that isomorphism between sociologies of knowledge and the presidents' occasioned response to occasioned constraints, the thesis amounts to a practical resolution of Mannheim's paradox. The trans-scalar interaction of fractal ordering shows that sociological knowledge is achieved pragmatically in a space defined by its epistemological difficulties.

description: Background— Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 infection is associated withcerebrovascular events. Given the novelty of this viral illness, there is paucity of data regarding this association. Weaim to provide further evidence by reporting risk factors, clinical course and outcome in patients with SARS-CoV-2infection presenting at our institute with cerebrovascular complications.Methods— We extracted a cross-sectional analysis of data from our institutional HOPES stroke registry toidentify patients with SARS-CoV-2 infection who had cerebrovascular events. We analyzed the data and compareddemographics, laboratory, and clinical presentations across all stroke patients during the peak pandemic period.Results— 22 patients with SARS-CoV-2 infection were treated at our medical center between March 2020 andOctober 2020. Majority of these patient (~80%) suffered acute ischemic strokes while ~20% experienced intracra-nial hemorrhage (ICH). We found that the majority of our cohort presented with neurological manifestations (77%)prior to the respiratory illness, yet the cause of mortality was largely secondary to the pulmonary complications ofCOVID-19 (56%). Patients with SARS-CoV-2 infection who suffered cerebrovascular events had a worse 90-dayoutcome, as defined by the modified Rankin Scale score. Additionally, patients with SARS-CoV-2 infection whoreceived chemical or mechanical thrombolysis had higher rate of intracranial bleeding, with 5 of the 7 (71%) treatedpatients dying during their hospitalization.Conclusions— Neurological outcome appears to be worse in patients with SARS-CoV-2 infection when comparedto patients without SARS-CoV-2 infection experiencing cerebrovascular events.

description: In this paper we investigate dark matter structure formation in the normal branch of the Dvali-Gabadadze-Porrati (nDGP) model using the PINOCCHIO algorithm. We first present 2nd order Lagrangian perturbation theory for the nDGP model, which shows that the 1st- and 2nd-order growth functions in nDGP are larger than those in ΛCDM. We then examine the dynamics of ellipsoidal collapse in nDGP, which is accelerated compared to ΛCDM due to enhanced gravitational interactions. Running the nDGP-PINOCCHIO code with a box size of 512 Mpc/h and 1024*1024*1024 particles, we analyze the statistical properties of the output halo catalogs, including the halo power spectrum and halo mass function. The calibrated PINOCCHIO halo power spectrum agrees with N-body simulations within 5% in the comoving wavenumber range k < 0.3 (h/Mpc) at redshift z = 0. The agreement is extended to smaller scales for higher redshifts. For the cumulative halo mass function, the agreement between N-body and PINOCCHIO is also within the simulation scatter.

description: We perform a numerical study of the three-dimensional Random Field Ising Model at T=0. We compare work distributions along metastable trajectories obtained with the single-spin flip dynamics with the distribution of the internal energy change along equilibrium trajectories. The goal is to investigate the possibility of extending the Crooks fluctuation theorem to zero temperature when, instead of the standard ensemble statistics, one considers the ensemble generated by the quenched disorder. We show that a simple extension of Crooks fails close to the disordered induced equilibrium phase transition due to the fact that work and internal energy distributions are very asymmetric.
High Stable Aqueous Foams as Improved Fracking Fluid for Unconventional Reservoirs

Subjects: Civil geotechnical engineering

description: Due to their relatively low water content and high viscosity, foamed fluids are regarded as a promising alternative to water-based fracking fluids. However, foams are thermodynamically unstable, and the poor long-term stability significantly impedes their subsurface applications, especially under the high temperature conditions. Consequently, the primary objective of this study is to develop a highly stable aqueous foam that can be used as a stimulation fluid, utilising various stabilisers such as surfactants, polymers, and nanoparticles.
