title: Estimating Optimum Overstory Vegetation Reduction for Increasing Understory Production
Creators: name: Tanaka, John A.
Publisher: name: Utah State University
Year: 1986

description: The purpose of this study was to investigate analytical approaches for estimating the optimum (profit maximizing) rate of initial overstory kill for increasing seasonal forage availability on a specific ranch. The models were developed using the big sagebrush (Artemisia tridentata) - crested wheatgrass (Agropyron cristatum, A. desertorum) vegetation type on a Utah cow-calf-yearling operation as an example. The models should be applicable on any ranching situation where understory forage production is constrained by the establishment and growth of undesirable overstory vegetation.
Three model forms were developed and compared for their applicability to on-the-ground investment decision making. Single treatment period (STP) static and dynamic models and a multiple treatment period (MTP) dyne.mic model were theoretically developed. Ee.ch model we.s formulated using e. biological production function relating under story production to ini tie.l kill percentage, e. cost of overstory kill function fore. specific overstory reduction method, and a derived demand function for seasonal forage availability. The production function was estimated in both static and dynamic forms for use in the different models. The remaining functions were used in the same form for a11 model applications.
Results indicated that the STP static optimization model holds the most promise for an on-the-ground decision making tool at the present time. Data to estimate dynamic production functions over a variety of vegetation types and grazing management situations essentially do not exist. This deficiency makes the use of long-term dynamic models less feasible for current decisions. It does not, however, alleviate the need to recognize long-term biological and economic relationships in making such decisions. The STP static model indicated that for the example Utah ranch a target big sagebrush kill rate between 89 and 100 percent would be optimal depending on the derived demand and cost of kill functions used. Target kill rates other than the optimum would represent potentially significant opportunity costs to this particular operation. The optimal solution obtained by this method is expected to change depending on the situation being analyzed. The model must be applied on a specific ranch basis and was not designed to make general recommendations.

description: Understanding how macroscopic systems exhibit irreversible thermal behavior has been a long-standing challenge, first brought to prominence by Boltzmann. Recent advances have established rigorous conditions for isolated quantum systems to equilibrate to a maximum entropy state, contingent upon weak assumptions. These theorems, while powerful, apply for a sudden quench. However, natural processes involve finite-time perturbations or quenches, which raises a crucial question: Can these systems still equilibrate under more realistic, finite-time dynamics? In this work, we extend the established results to account for finite-time quenches, demonstrating that even under finite-time perturbations, the system will equilibrate provided it populates many significant energy levels. While the mathematical proof is more intricate than in the instantaneous case, the physical conclusion remains the same: sufficient perturbation leads to equilibration. Our results provide a broader and more physically realistic framework for understanding thermalization in isolated quantum systems

title: Effectiveness of Earthen Escape Ramps in Reducing Big Game Mortality in Utah
Creators: name: Hammer, Mary L.
Publisher: name: Utah State University
Year: 2001

description: One-way escape gates and earthen escape ramps are structures used to enable deer to exit the highway right-of-way along fenced roads. I compared the use of one-way escape gates and earthen escape ramps by mule deer on two highways in Utah to determine if deer exhibited a preference for either structure. Results showed that earthen escape ramps were used by mule deer 8-11 times more frequently than one-way gates. Highway mortality data suggest that the installation of the escape ramps likely reduced mortality of mule deer in both study locations, because we could not attribute reductions in mortality to decreased population densities of mule deer in either location. Because they provide a topographic solution for exiting the right-of-way, escape ramps may reduce deer mortality along other game-fenced highways throughout the United States. Management recommendations that address the placement and spacing of escape ramps will help wildlife and highway personnel implement the use of these ramps in other locations.
A cost-benefit analysis was conducted to determine if the cost of ramp installation was offset within a reasonable time period by the monetary savings associated with reduced deer-vehicle collisions. The cost-effectiveness of installing the earthen escape ramps at both locations was determined by using the number of successful ramp crossings and potential deer mortality levels to generate projected monetary losses associated with varying mortality levels. The assumption was made that at least some of these deer that crossed successfully would have been involved in a deer-vehicle collision had the ramps not been in place. Six arbitrary levels of potential mortality (from 2% to 15%) were generated based on those assumptions. These percentages were multiplied by the number of successful deer crossings at each location to generate potential deer mortality numbers. The number of deer mortalities was then multiplied by the average economic loss of a deer-vehicle collision ($3,845) to obtain an estimate of the mitigated benefits of installing the ramps through 1999. These values were compared to the cost of installing ramps at each location to determine the amortization period.
Results showed that the cost of installation of earthen escape ramps is very rapidly offset by the benefits gained in deer survival and reduced automobile collisions. At the 2% mortality level, the cost of ramp installation in both locations was offset by the monetary savings associated with reduced deer-vehicle collisions by the second year. Heavy use of the escape ramps as well as reduction in mortality observed at both study sites indicate that the mitigation benefits may be much greater than those projected at the 2% mortality level. Installing earthen escape ramps on big-game fenced highways is a very cost-effective way to further reduce deer mortalities along roadways.
Attentional bias to social media cues : an eye tracking study
Creators: name: Marshall, AJ
Publisher: name: University Of Tasmania
Year: 2023

description: Many behaviours provide short-term rewards. However, when adverse consequences begin to occur, and individuals continue engaging in the behaviour, it becomes maladaptive, and may develop into a behavioural addiction. Determining which behaviours should be classified as behavioural addictions requires an understanding of the mechanisms that underly addiction. Attentional bias is believed to be an underlying mechanism for both substance abuse and gambling disorders, but there is limited research about its connection to Problematic Social Media Use (PSMU). This study used eye-tracking technology to explore whether individuals with differing levels of PSMU, measured by a post-experimental survey, had different attentional biases in the form of saccadic reaction time. The sample included 26 participants, aged 20-32 (M = 24.65, SD = 3.82) Results indicated that there was no effect of attentional bias on reaction time in individuals with differing levels of PSMU. However, measures of PMSU were significantly correlated with impulsivity and attention deficits, suggesting that there may be different factors involved in the maintenance of PSMU to other addictions. Further research with larger samples is needed to understand the role of attentional bias in PSMU and addiction.

description: Around the 1990s, there was a remarkable emergence of symphony orchestras in the autonomous communities in Spain, and thus a change in the cultural physiognomy of its environment. In 1994, the Orquesta Sinfónica de Galicia (OSG) created, for educational purposes, the Escuela de Práctica Orquestal (EPO); that became known as the Orquesta Joven de la Sinfónica de Galicia (OJSG) in 2002. In recent years we have witnessed a remarkable proliferation of such groups of young musicians throughout the Iberian Peninsula. The objective of this research is to study the degree of impact on the formation of professional musicians and the evolution of the educational work of the OJSG in its area of influence. Thus, the researcher manages data extracted from various documentary sources and statistical data. Former students’ interviews are also taken in consideration to verify the influence of this Youth Orchestra in their musical training and its overall role in improving the educational opportunities of its environment. The study tries to verify the establishment of a stable pool of professional musicians in Galicia under the influence of OJSG.

description: Many processes and models --in biological, physical, social, and other contexts-- produce trees whose depth scales logarithmically with the number of leaves. Phylogenetic trees, describing the evolutionary relationships between biological species, are examples of trees for which such scaling is not observed. With this motivation, we analyze numerically two branching models leading to non-logarithmic scaling of the depth with the number of leaves. For Ford's alpha model, although a power-law scaling of the depth with tree size was established analytically, our numerical results illustrate that the asymptotic regime is approached only at very large tree sizes. We introduce here a new model, the activity model, showing analytically and numerically that it also displays a power-law scaling of the depth with tree size at a critical parameter value.

description: Lean Methodology for Garment Modernization. This article presents the lean methodology for modernizing garment manufacturing, focusing on lean thinking, lean practices, automation development, VSM, and CRP, and how to integrate them effectively. While isolated automation of specific operations can improve efficiency and reduce cycle time, it does not necessarily enhance overall garment output and efficiency. To achieve these broader improvements, it is essential to consider the entire production line and process using VSM and CRP to optimize production and center balance. This approach can increase efficiency, and reduce manufacturing costs, labor time, and lead time, ultimately adding value to the company and factory.

description: We study double Higgs production in photon-photon collisions as a probe of the new dynamics of Higgs interactions in the framework of two Higgs Doublet Models. We analyze neutral Higgs bosons production and decay in the fusion processes, $γγ\to S_iS_j$, $S_i=h^0, H^0, A^0$, and show that both $h^0h^0$ and $A^0A^0$ production can be enhanced by threshold effects in the region $E_{γγ}\approx 2 m_{H\pm}$. Resonant effects due to the heavy Higgs, $H^0$, can also play a role in the cross section enhancement when it is allowed to decay to two light CP-even $h^0$ or to two light CP-odd $A^0$ scalars. We have scanned the allowed parameter space of the Two Higgs Doublet Model and found a vast region of the parameter space where the cross section is two orders of magnitude above the Standard Model cross section. We further show that the Standard Model experimental analysis can be used to discover or to constraint the two Higgs doublet model parameter space.

description: This paper develops and estimates a dynamic model of student enrollment, school choice, academic achievement and grade progression to evaluate the impacts of Mexico’s conditional cash transfer program Prospera on educational outcomes over grades 4-9. Academic achievement is measured by nationwide standardized test scores in mathematics and Spanish. Enrollment decisions are the outcomes of sequential decisions at each age from persons’ feasible choice sets, determined by the types of schools locally available and local-labor-market opportunities. The achievement production function has a value-added structure. Model parameters are estimated by maximum likelihood using nationwide administrative test-score data (the ENCEL data) combined with survey data from students and parents, census labor-market data, and geocoded school location data. The estimation approach controls for selective school enrollment in different types of schools, grade retention and unobserved heterogeneity. The results show that the Prospera program increases school enrollment and academic achievement for program beneficiaries in lower-secondary school grades (grades 7-9). The average test score impacts are 0.09-0.13 standard deviations in mathematics and 0.03-0.05 standard deviations in Spanish. Students from the most disadvantaged backgrounds experience the largest impacts. The availability of telesecondary distance-learning schools is shown to be an important determinant of the Prospera program’s impacts on educational outcomes.

description: DMAOVC.BAS is a computer program written in the compiler version of microsoft basic which performs factorial analysis of variance/covariance with expected mean squares. The program accommodates factorial and other hierarchical experimental designs with balanced sets of data. The program is writ ten for use on most modest sized microprocessors, in which the compiler is available. The program is parameter file driven where the parameter file consists of the response variable structure, the experimental design model expressed in a similar structure as seen in most textbooks, information concerning the factors (i.e. fixed or random, and the number of levels), and necessary information to perform covariance analysis. The results of the analysis are written to separate files in a format that can be used for reporting purposes and further computations if needed.

Behavioural genetics in court : the impact of mitigating versus aggravating evidence, and recidivism
Creators: name: Mitchell, GF
Publisher: name: University Of Tasmania
Year: 2023

description: Evidence for genetically predisposed behaviours, particularly of impulsivity and aggression, has been presented in court cases, resulting in concern as to how persuasive this evidence might be. The present study aimed to determine if legal party presentation of behavioural genetic evidence, as well as inclusion of recidivism evidence, could differ the recommended sentencing and perceptions of the defendant. A total of 168 participants (females = 123) aged 18 to 75 were included and were randomly assigned to one of four conditions that included evidence presentation (defence or prosecution) and recidivism (first or fifth account). Participants read a vignette on an aggravated assault, diverging only by the conditions' differences, that included genetic evidence for the assailant having a genetic predisposition to impulsive and aggressive behaviours. Participants acted as mock jurors to recommend sentence severity and report perceptions of the defendant's culpability and dangerousness. It was determined that behavioural genetic evidence presentation by the defence resulted in slightly lower recommended sentence severity than the presentation by the prosecution, and that a history of recidivism resulted in a small increase in the perception of the defendant's dangerousness. The findings demonstrate that the prosecution could manipulate this evidence to aggravate a court case.
title: A Social Analysis of Grazing Management on National Forest Lands: A Case Study in Catron County, New Mexico
Creators: name: Watts, Alexis S.
Publisher: name: Utah State University
Year: 1999

description: The rural west in this country faces increased national pressure concerning the iii management of natural resources on public lands. Issues regarding natural resource management are becoming more important as they continue to affect rural communities and capture the attention of a variety of interest groups. Natural resource managers are increasingly required to consider social dimensions of resource use and management. Lack of consideration in these areas can lead to dissatisfied, and even hostile, local residents and interest groups. Often land managers face criticism from many groups at once as a result of management decisions.
This study analyzed a particular resource issue in a particular region of the west: grazing management in Catron County, New Mexico. The findings indicate a complex social structure with an historical base in natural resource dependence, and a personal independence from highly regulated grazing management. Changes in national legislation and changes in the Forest Service over time have contributed to the erosion of relationships between the Forest Service and ranchers and environmentalists. A socially informed, pragmatic and proactive approach to grazing management is currently lacking in Catron County.

Em 2005 foi erigido um monumento a esta adufeira cuja voz e “toque no adufe” foram registados por sucessivos etnógrafos desde o início dos anos 1960. “Pastora”, “tecedeira”, “trabalhadora rural”, “semiletrada”, segundo o inquérito feito por Giacometti em 1970, conquistou visibilidade à escala nacional através dos media. Atualmente, em 2015, os registos da sua voz e “toque” do adufe disponíveis no Youtube têm um número de visualizações muito superior ao número de habitantes da aldeia de Penha Garcia, testemunhando exemplarmente o alcance e o impacte da sua voz. Este estudo etnomusicológico sobre a cantadeira e adufeira Catarina Sargenta tem como objetivos contribuir para o conhecimento do papel da etnografia musical na construção de ícones da música de matriz rural em Portugal; conhecer o percurso de vida de Catarina Sargenta e perceber como, no século XXI, tradições musicais de matriz rural objetificadas (Handler 1988) por sucessivos etnógrafos constroem o lugar de Penha Garcia. A investigação sustenta­se em pesquisa arquivística e bibliográfica e em trabalho de campo, o qual incluiu a realização de entrevistas a pessoas que conviveram com a adufeira e a observação de eventos.

title: Seasonal Feeding Behavior and Forage Selection by Goats in Cleared and Thinned Deciduous Woodlands in Northeast Brazil
Creators: name: Mesquita, Roberto Cesar Magalhaes
Publisher: name: Utah State University
Year: 1985

description: The seasonal feeding behavior, forage preferences and body weight responses of goats were studied under three densities of woodland (called caatinga), and under three stocking rates. The experiment was located in the semi-arid tropics of northeastern Brazil at 3 42' South latitude, and 40 21' West longitude at an elevation of 75 meters. Mean annual precipitation of the area is 832 mm.
Removing the shrubs and trees increased yields of herbaceous only on partially-cleared sites. Goats gained body weight (kg BW/ha) during the wet season, with the cleared treatment showing the best body weight response per unit of land. However during the dry season, animals lost weight probably due the low quality and quantity of available forage.
The botanical composition of goats' diets showed them to be mixed feeders, consuming grasses, forbs and browse in various combinations depending on the season and the array of forage species available. During the dry season standing hay from herbaceous species and regrowth of some woody evergreen species were the principal forages. Animals maintained body weight on this forage. However, leaf litter was an important component of goats' diets during the dry season, but was inadequate for weight maintenance.
Goats i n all treatments spent the least time grazing during the wet season and the most time during the beginning of the dry season. They spent the most time lying ruminating during the dry season and the least time during the wet season. Forage quality was probably a limiting factor to effective animal response during the dry season.
Goats exhibited dislike for rain and wet conditions. They grazed freely when the temperatures were high (35 to 39 C). However, periods of high temperature corresponded to periods of low relative humidity, perhaps moderating the discomfort factor of combined high temperatures and high humidity.

title: Utilization of Spatially Distributed Soil Resources by Several Species Common to the Great Basin
Creators: name: Duke, Sarah
Publisher: name: Utah State University
Year: 1998

description: Heterogeneous spatial and temporal distributions of soil resources important to plant growth have been documented in the sagebrush steppe ecosystem. There can exist as much variability in soil resources within the root zone of individual plants as exists across an entire field. The objective of this dissertation research was to evaluate how plants respond to, utilize and influence the spatial heterogeneity of soil resources. The three specific sets of questions addressed are outlined in the three main chapters of this dissertation.
My first study addressed how the number and concentration of phosphorus (P) patches in the root zone of an individual Artemisiaplant influenced the ability of the plant to increase root P uptake capacity from the enriched patches as compared to roots from unenriched soil. I found that root uptake kinetics in the most enriched patches in general was not limited by the number or concentration of phosphorus patches experienced by the plant. However, the plants could modulate the quantity of P acquired from a target patch as the number of patches experienced increased.
My second study addressed how six species common to the Great Basin, which represent three different growth forms, utilized nitrogen (N) from patches or a uniform distribution. The two species within the two perennial growth forms, shrub and tussock grass, revealed different capacities for acquiring N from concentrated patches immediately adjacent to a plant and from N applications at a distance from plants. This suggests the potential for different root foraging behavior. The two annual species used concentrated N patches more effectively than uniform applications.
My third study described decimeter scale variability of soil water potential (Ψs) in the interspace of two perennial plants at different time scales and at different soil moisture conditions. The mean Ψs was more spatially consistent in the interspace between plants during a midsummer dry period compared to an early summer period. Diel Ψs fluctuations during an early summer dry period was more spatially consistent than a midsummer dry period. When soil moisture was recharged by precipitation there were no spatial diel patterns and the mean Ψs was autocorrelated across the area evaluated.

description: Using psi(3770) --> DDbar events collected with the CLEO-c detector at the Cornell e+ e- storage ring, tagged by fully reconstructing one D meson in a hadronic decay mode, we measure absolute branching fractions and differential decay rates for D0 --> pi- e+ nu(e), D+ --> pi0 e+ nu(e), D0 --> K- e+ nu(e), and D+ --> anti-K0 e+ nu(e). The measured decay rates are used to study semileptonic form factors governing these transitions and to test unquenched Lattice QCD (LQCD) calculations. We average our results with previously published CLEO-c measurements of the same quantities using a neutrino reconstruction technique. Combining LQCD calculations of form factor absolute normalizations f+(0) and measurements of f(pi)+(0)*|Vcd| and f(K)+(0)*|Vcs|, we find |Vcd| = 0.223(8)(3)(23) and |Vcs| = 1.019(10)(7)(106), where the uncertainties are statistical, experimental systematic, and from LQCD, respectively.

description: O presente artigo faz parte de uma proposta de estudo sobre a presença da ação da palavra em cena na dança contemporânea e concentra-se n’As Lágrimas de Saladino, trabalho de Rui Horta com Tiago Rodrigues que, entre outros, é temática alvo de investigação. Independentemente das relações de sentido a que apela, a palavra falada em cena é considerada pela sua natureza física e pensada enquanto processo com capacidade para atuar através do seu valor sonoro e vocal. Observando a justaposição e compatibilidade de ideias de diversos autores, são tópicos principais de discussão o valor sonoro da palavra e a sua percepção no constante jogo de relações em cena. A partir da dimensão da concretude sonora ensaia-se uma possibilidade de vínculo da palavra falada em cena com o corpo e a dança contemporânea. O processo de dar palavra ao corpo que dança diante de Outro pode perceber-se como forma de dar voz e potencializar a dança e o evento teatral e performativo. Da perspetiva d’As Lágrimas de Saladino – que oferece vasto material para o exercício da consciência de escuta – a experiência da sonoridade da palavra falada sobrepõe-se ao seu sentido linguístico o que permite-nos considerar, também, falar de dança como processo de uma experiência percetiva de natureza auditiva.

description: We report the discovery of a high proper motion L subdwarf ($μ$ =0.617arcsec/yr) in the Sloan Digital Sky Survey spectral database. The optical spectrum from the star SDSS J125637-022452 has mixed spectral features of both late-M spectral subtype (strong TiO and CaH at 7000A) and mid-L spectral subtype (strong wings of KI at 7700A, CrH and FeH), which is interpreted as the signature of a very low-mass, metal-poor star (ultra-cool subdwarf) of spectral type sdL. The near infrared (NIR) (J-Ks) colors from 2MASS shows the object to be significantly bluer compared to normal L dwarfs, which is probably due a strong collision induced absorption (CIA) due to H2 molecule. This is consistent with the idea that CIA from H2 is more pronounced at low metallicities. Proper motion and radial velocity measurements also indicate that the star is kinematically "hot" and probably associated with the Galactic halo population.

Creators: name: Jackson, Robert B.
Publisher: name: Utah State University
Year: 1989

description: Root exploitation of enriched soil microsites was examined for the tussock grasses Agropyron desertorum and Agropyron spicatum and the shrub Artemisia tridentata. Two mechanisms of exploitation of the microsites were examined: root proliferation and changes in nutrient uptake capacity. One day after nutrient solution was applied to small soil patches, the mean relative growth rate of Agropyron desertorum roots in enriched patches was two to four times greater than for roots of the same plants in soil patches treated with distilled water. This rapid and striking root proliferation occurred in response to N-P-K enrichment as well as to P or N enrichment alone. Agropyron spicatum showed no tendency to proliferate roots in enriched soil patches during the two-week experiments. The shrub Artemisia tridentata proliferated roots within one day of initial solution injection in the N-enrichment experiment, but root proliferation of this species was more gradual and less consistent in other experiments. The ability of Agropyron desertorum partly explain its to proliferate superior ability roots to rapidly may exploit soil nutrients compared to Agropyron spicatum in Great Basin rangelands of North America.
Changes in nutrient uptake capacity in enriched soil patches were also studied for each species. rapid changes in uptake capacity of plant roots Large and from the field were observed after creation of nutrient-rich patches in the soil. Phosphate uptake of excised roots from enriched soil patches was roots of control patches as much as 80% greater than for treated with distilled water. These increases in uptake capacity took place within one week of patch treatment for all three species. A follow-up experiment showed increases within three days of patch treatment. These results showing rapid physiological plasticity in roots exploiting nutrient patches have important implications for nutrient belowground competition among plants.
title: Phosphorus Dynamics in Dingle Marsh, Idaho
Creators: name: Herron, Rex C.
Publisher: name: Utah State University
Year: 1985

description: Phosphorus mass-balance studies of Dingle Marsh, Idaho indicated that the marsh was an annual net sink for total suspended sol ids and all forms of phosphorus under consideration: total phosphorus, particulate phosphorus, total dissolved phosphorus, dissolved organic phosphorus, and orthophosphate phosphorus. During some months, however, more phosphorus was exported from the marsh than entered.
Phosphorus mass-balance dynamics were compared between night and day. Total suspended solids and particulate phosphorus dynamics were controlled by sedimentation of particulate material, a physical process, and were unaffected by light conditions. Dissolved organic and ortho-phosphorus were affected by light conditions indicating, at least indirectly, that biological processes were affecting dissolved phosphorus dynamics. These phosphorus fractions were occasionally released in large amounts by the marsh at night.
An in situ enclosure experiment was performed to determine major sites of phosphorus uptake/release. A twentyfour-hour rate of particulate phosphorus decrease in the enclosures could be predicted (r2=0.89) by knowing the initial concentration of total suspended solids. On a twentyfour-hour basis, periphyton, detritus, and live bulrushes tended to remove more dissolved organic phosphorus from the water than they added to it while plankton and sediments added dissolved organic phosphorus to the water. Orthophosphates were removed from the water by plankton, detritus, and periphyton with plankton dominating the changes. Live bulrushes or sediments within the bulrush system tended to be a source for orthophosphates.
The open water ecosystem was a greater net source for dissolved organic phosphorus than the bulrush system. The open water system was a greater net sink, however, for orthophosphates, than was the bulrush community.
Dowel Action in reinforced concrete construction (beam-column connections)

description: The transfer of shear in a beam-column joint by dowel action alone was experimentally and analytically studied. The laboratory work involved the shear capacity determination of individual reinforcing steel dowels embedded in concrete. Two main series of experimental tests were conducted on bottom and top dowels - component parts of a beam-column joint. All experimental results were compared to a theoretical analysis. The theoretical analysis consisted of choosing a rational physical model, i.e., a mode of behaviour for each of the two component parts of the joint. No curve-fitting to the experimental results was done. These results do show, however, that the model provides a safe lower bound on the shear capacity of the joint. Also, the model permits reasonable extrapolation to other design problems where the conditions of the problem are not exactly the same as those imposed during the experimental tests. A design example of predicting the shear capacity of a beam-column joint on the basis of dowel action of the reinforcing steel is presented for any combination of top and bottom dowels.

description: Neste artigo procuro refletir sobre uma prática performativa musical que tem por característica utilizar a loop station – máquina que permite a gravação e reprodução de áudio de forma cíclica (o loop). Em 2001, a empresa Boss lançou no mercado a primeira loop station. Foi desenvolvida como um pedal, ou seja, para se operar com os pés, de forma a possibilitar aos instrumentistas um auto acompanhamento. A loop station permite ao performer construir camadas de áudio de forma a criar uma estrutura (ritmo, linhas de baixo, harmonia, etc.) sobre a qual performa seu solo. Essa vertente é comummente designada por live loops. Assim, este trabalho propõe perceber em que sentido a tecnologia da loop station põe em questão o conceito de prática performativa musical (Béhague, 1984) e suas implicações no e para o mercado da música. Parto da reflexão de minha situação enquanto looper (performer que incorpora a loop station em seu setup), de entrevistas com outros loopers e da análise de publicações científicas que abordem a utilização da loop station em performance musical, além de websites e comunidades virtuais acerca desse tema.

description: This paper presents a prototype of a low-cost Unmanned Surface Vehicle (USV) that is operated by wave and solar energy which can be used to minimize the cost of ocean data collection. The current prototype is a compact USV, with a length of 1.2m that can be deployed and recovered by two persons. The design includes an electrically operated winch that can be used to retract and lower the underwater unit. Several elements of the design make use of additive manufacturing and inexpensive materials. The vehicle can be controlled using radio frequency (RF) and a satellite communication, through a custom developed web application. Both the surface and underwater units were optimized with regard to drag, lift, weight, and price by using recommendation of previous research work and advanced materials. The USV could be used in water condition monitoring by measuring several parameters, such as dissolved oxygen, salinity, temperature, and pH.

description: This report is both a users guide and a programmers manual for running and modifying the program SHAMAT, an interactive matrix calculator. The program is written in Turbo Pascal version 3.0 for MS-DOS computers. This software enables the user to type in matrix equations for solving statistical problems such as multiple regression, analysis of variance, etc. All matrix operations necessary for linear models analysis are included in this program. Since each operation uses a separate subroutine, program enhancement, modification and updating is demonstrated to be easy.
title: Disturbed Alpine Ecosystems: Seedling Establishment of Early and Late Seral Dominant Species
Creators: name: Chambers, Jeanne C.
Publisher: name: Utah State University
Year: 1987

description: This study examined the effects of seedbed and seedling environment on establishment of early and late seral dominant alpine species. Species studied included late seral dominant forbs (Geum rossii, Artemisia scopulorum, and Polemonium viscosum), early seral dominant forbs (Potentilla diversifolia and Sibbaldia procumbens), a late seral dominant grass (Festuca idahoensis), and early seral dominant grasses (Calamagrostis purpurascens and Deschampsia cespitosa). Germination responses of each species to wet vs. dry cold stratification and light vs. dark conditions were investigated. No statistical differences were observed in the seed germination of early and late seral dominant forbs or early and late seral dominant grasses, but significant differences were observed in the responses of grasses and forbs. Seed germination of forbs was greater under light than dark conditions and following wet cold storage.
Effects of fertilization on growth responses and nutrient uptake of G. rossii and D. cespitosawere evaluated in a factorial greenhouse experiment in which seedlings of each species were grown at four levels of nitrogen (N) and phosphorous (P). The late seral dominant forb responded more like a species from a low-nutrient environment exhibiting lower relative growth rates, higher root:shoot ratios, and a smaller response to N than the early seral dominant.
A field experiment on the Beartooth Plateau, Montana, examined the soil environment and seedling emergence, growth, and survival of seeded early and late seral dominants on loamy sand soils of a severe disturbance and on peat soils of an undisturbed area during two growing seasons. Effects of fertilizer and mulch were examined on the severely disturbed area. Differences between uncleared turf and turf cleared of vegetation (gap disturbance) were evaluated on the undisturbed area. The gap disturbance had higher levels of N and P and warmer soil than the severe disturbance or vegetated undisturbed area. Soil water potentials were never low enough to result in plant stress. Seedling growth was slow - .005 g to .04 g dry weight the first growing season and .02 g to .20 g the second growing season. Growth was greatest on the gap disturbance and on fertilized plots of the severely disturbed area. Early seral dominants had the largest seedlings and the smallest R/R+S ratios. Mortality was low - odds of .50 were rarely exceeded even after two years. Survival was higher on warm, nutrient rich soils of the gap disturbance. Mulch increased emergence and survival on the severe disturbance. Fertilization increased mortality, probably because an initial pulse of N was followed by a rapid decline. Higher mortality occurred in 1986 than 1985 as 1986 had a shorter growing season and cooler air and soil temperatures early in the growing season.

description: Oscillating eclipsing Algols (oEAs) are remarkable systems which allow us to determine accurate fundamental stellar parameters (mass, radius) and probe the stellar interiors through pulsations. TZ\,Dra is an oEA system containing a $δ$ Scuti component. To examine particular characteristics of such close systems including pulsations and mass transfer, we present a detailed photometric and spectroscopic study of TZ\,Dra. With the analysis of high-resolution spectra, the orbital parameters were determined by the radial velocity analysis and the atmospheric parameters were derived for the primary component. The binary modelling and the pulsational frequency analysis was carried out using the TESS data set. The H$α$ line profiles show the signature of mass transfer from the cool to the hot binary component. The conclusion of mass transfer/mass loss in the system was supported by the analysis of the orbital period changes. As a result, it was found that there is $3.52 \times 10^{-9}$ $M_\odot$/year mass loss from the system most probably through the hotspot and stellar winds. Additionally, most pulsation frequencies originating from the primary component were found to be spaced by harmonics of the orbital frequencies in particular, twelve doublets spaced by $2f_{\rm orb}$ were detected from which we infer that this star a tidally tilted pulsator. A mean p-mode frequency spacing of $\approx 7.2 $d$^{-1}$ was found as well.
