title: Autecological Characteristics of Chrysopogon aucheri and Cymbopogon jwarancusa, Dominant Rangeland Grasses in Baluchistan
Creators: name: Saleem, Mohammad
Publisher: name: Utah State University
Year: 1990

description: Controlled environment experiments were designed to study the germination, seedling development, and defoliation responses of Chrysopogon aucheri and Cymbopogon jwarancusa to better understand their xv autecology and potential use in range improvement programs in Baluchistan.
In experiment 1, Cymbopogon jwarancusa had greater seed fill and viability than Chrysopogon aucheri. When incubated at six different alternating temperature regimes, seeds of Cymbopogon jwarancusa had greater cumulative germination at five temperature regimes and faster germination at the colder temperature regimes than Chrysopogon aucheri.
In experiment 2, seedling shoot and root development was characterized at 15-day intervals over a 60-day period. Seedlings of both species had a "panicoid'' type seedling morphology. Chrysopogon aucheri and Cymbopogon �warancusa developed comparable numbers of leaves and tillers per plant during the 60-day period. Chrysopogon aucheri had a greater number, length, and dry weight of primary and seminal roots than Cymbopogon jwarancusa at 30 and 60 days, respectively. Adventitious root length was also higher for Chrysopogon aucheri than Cymbopogon jwarancusa at 60 days. Seedlings of both species had similar shoot:root ratios and relative growth rates. In experiment 3, seedlings of both species were planted in rnonocultures and in a 50:50 mixtures. Defoliation treatments, implemented 32 weeks after emergence, included: equally clipping all plants of both species zero, one, two, or three times (at 4-week intervals) in monoculture and mixture; and clipping one species zero, one, two, or three times (at 4-week intervals) without clipping the associated species in mixture. Both species remained vegetative and did not differ in leaf and tiller development until about 32 weeks after emergence. During later growth, Chrysopogon aucheri reproduced while Cymbopogon jwarancusa remained vegetative. cymbopogon jwarancusa produced more tillers on control plants and defoliated plants (mainly in monoculture). At lower frequencies of defoliation Chrysopogon aucheri produced more shoot and root biomass than Cymbopogon jwarancusa (mainly in mixture). In 50:50 mixtures when one species was defoliated and the other not, both species were comparable in shoot dry weight; however, Chrysopopgon aucheri was superior to Cymbopogon jwarancusa in root dry weight at all defoliation regimes. The initial standing crop and subsequent regrowth of Chrysopogon aucheri were comparable or higher in crude protein and digestibility than Cymbopogon jwarancusa.

A model for the analysis of packet switching computer networks
Creators: name: Alemparte, Miguel D.
Publisher: name: University of British Columbia
Year: 2010

description: An overview of the computer networks currently being developed is presented. Three types of network design are distinguished - packet switching, line switching and Newhall loops. Reference is made to several models developed during the design of these networks, but only those concerned with packet switching are described in detail. A gueueing model emerges as a feasible alternative to the more expensive simulation models. This model is developed to include the basic logic of the message switching centres (nodes) and used as the backbone to a heuristic procedure that considers limited capacity buffers and blocking at the nodes. Key words and phrases: Data transmission, computer nets, packet switching, switching centre, interactive computation, resource sharing, queueing network, Markovian queue, steady state.

description: To fight against the evolution of malware and its development, the specific methodologies that are applied by the malware analysts are crucial. Yet, this is something often overlooked in the relevant bibliography or in the formal and informal training of the relevant professionals. There are only two generic and all-encompassing structured methodologies for Malware Analysis (MA) - SAMA and MARE. The question is whether they are adequate and there is no need for another one or whether there is no such need at all. This paper will try to answer the above and it will contribute in the following ways: it will present, compare and dissect those two malware analysis methodologies, it will present their capacity for analysing modern malware by applying them on a random modern specimen and finally, it will conclude on whether there is a procedural optimization for malware analysis over the evolution of these two methodologies.
title: Natural-Resources Education in Utah's Public Schools
Creators: name: Van Niel, John J.
Publisher: name: Utah State University
Year: 1990

description: Several aspects of natural-resources education were explored in this study. First, a statewide survey of science, social studies, and elementary teachers was conducted to determine the current form and extent of natural-resources education in Utah. Returns were received from 51% of the surveyed teachers. The percent of time devoted to natural resources, the factors affecting natural-resources instruction, and the need to improve that instruction were assessed.
Utilizing that information, the Natural-Resources Curriculum Framework was developed. The Framework is designed to provide educators with the essential concepts to be included in a comprehensive natural-resources program.
Finally, examples of classroom support materials were created as extensions of the Framework. These materials, specifically designed for geography teachers, cover a wide variety of concepts involving natural resources.

description: We studied the asymmetry between valence and conduction bands in single-walled carbon nanotubes (SWNTs) through the direct observation of spin-singlet transverse dark excitons using polarized photoluminescence excitation spectroscopy. The intrinsic electron-hole (e-h) asymmetry lifts the degeneracy of the transverse exciton wavefunctions at two equivalent K and K' valleys in momentum space, which gives finite oscillator strength to transverse dark exciton states. Chirality-dependent spectral weight transfer to transverse dark states was clearly observed, indicating that the degree of the e-h asymmetry depends on the specific nanotube structure. Based on comparison between theoretical and experimental results, we evaluated the band asymmetry parameters in graphene and various carbon nanotube structures.

description: Software engineering is continuously facing the challenges of growing complexity of software packages and increased level of data on defects and drawbacks from software production process. This makes a clarion call for inventions and methods which can enable a more reusable, reliable, easily maintainable and high quality software systems with deeper control on software generation process. Quality and productivity are indeed the two most important parameters for controlling any industrial process. Implementation of a successful control system requires some means of measurement. Software metrics play an important role in the management aspects of the software development process such as better planning, assessment of improvements, resource allocation and reduction of unpredictability. The process involving early detection of potential problems, productivity evaluation and evaluating external quality factors such as reusability, maintainability, defect proneness and complexity are of utmost importance. Here we discuss the application of CK metrics and estimation model to predict the external quality parameters for optimizing the design process and production process for desired levels of quality. Estimation of defect-proneness in object-oriented system at design level is developed using a novel methodology where models of relationship between CK metrics and defect-proneness index is achieved. A multifunctional estimation approach captures the correlation between CK metrics and defect proneness level of software modules.

Year: 2023

description: This thesis is a study of the first permanent occupation of Tasman Peninsula; The survey and purchase of land and the evolution of a land use pattern within the expanding boundaries so formed. The nature of the work has necessitated a heavy reliance on survey information in the Department of Lands and Surveys, from which maps and tables have been compiled, and the annual reports of the Pembroke District Surveyor between 1880 and 1935, Joshua Hinsby. Bush settlement is generally an anonymous process, the pioneers having little time to write, and thus Hinsby's comments provide an invaluable record of what was happening on the land.
title: Effects of Chiselling and Sulfur Fertilization on Infiltration, Soil Water Content, Peak Season Biomass Production, and Botanical Composition in the Ait Rbaa Perimeter
Creators: name: Tigma, Mohammed
Publisher: name: Utah State University
Year: 1990

description: This study evaluated the effectiveness of chiselling and elemental sulfur fertilization in improving an upland and a swale range site with fine loamy, carbonatic, typic calcixeroll soils in the Ait Rbaa Perimeter of central Morocco. Ponding infiltration, soil water content on a mass basis of the 0- to 10-cm and 10- to 20-cm soil layers, peak season biomass production, and botanical composition were monitored during the two growing seasons following the treatments (1984/85 and 1985/86). Chiselling significantly improved infiltration on both sites, although the improvement was greater on the finer and less stony swale site, where chiselling resulted in more stable ridges. The land treatment also increased the average water content by weight of the 0- to 20-cm soil layer. The increase was more frequent on the upland site and most pronounced on its o- to 10-cm surface soil layer. In the chiselled treatments, average soil water content decreased with soil depth on the upland site while it increased on the swale site because of differential furrow stability and soil texture. Both the average infiltration rates of 5 cm of water and the average water content varied with sampling time, although generally in opposite directions. The application of elemental sulfur at the rates of 0, 30, and 60 kg ha-1 did not significantly affect any of the measured variables. Average peak season biomass production was 11% greater with chiselling. Chiselling also positively affected botanical composition on the upland site by depressing average forb proportion and increasing legume ratio in the first growing season. The gain in biomass does not seem to be high enough to strongly recommend chiselling in the Ait Rbaa Perimeter before performing an economic analysis of the operation.

Creators: name: Englund, Ronald A.
Publisher: name: Utah State University
Year: 1991

description: Microhabitat use by cutthroat trout and macrohabitat use by both cutthroat and rainbow trout were studied i n the Green River below Flaming Gorge Dam during the winters of 1988 and 1989. Microhabitat parameters used by cutthroat trout, such as focal velocity, depth, and fish elevation, differed significantly in eddies, runs, and riffles. Mean focal velocities in runs were 0.79 body lengths/seconds (bl/s), in riffles 0.66 bl/s, and in eddies 0.24 bl/s. Cutthroat trout size also varied significantly with macrohabitat; larger fish were found in riffles.
Macrohabitat use by cutthroat trout and rainbow trout differed significantly among species, macrohabitat types, and months. Both rainbow trout and cutthroat trout macrohabitat use shifted from lower velocity habitats during winter to faster velocity habitats in summer. Cutthroat trout and rainbow trout used macrohabitats at seasonally differing rates. Riffles were never selected in proportion to their abundance, especially during high winter discharges. Cutthroat trout implanted with radiotransmitters exhibited little movement during diel monitoring and did not change their occupation of macrohabitats.
title: Effect of Fertilization on Woody Plant Chemistry: The Role in Diet Selection by Goats
Creators: name: Gobena, Amanuel
Publisher: name: Utah State University
Year: 1988

description: Lack of forage quantity and quality limit livestock production during the dry season in northeast Brazil. Coppice produced following cutting of tree species in this area has the potential to increase forage quantity and quality during the dry season, because trees that coppice retain green foliage throughout most of the dry season. However, the palatability of coppice is often low.
From a theoretical standpoint, woody plants with inherently slow growth rate should be less palatable to herbivores than plants with inherently fast growth rates, because plants that grow slowly allocate more carbon to compounds such as tannins and resins that reduce palatability. I tested this hypothesis with four tree species (Mimosa caesalpiniaefolia, Croton sonderianus, Auxemma oncocalyx, and Caesalpinia bracteosa) growing on both fertile (non-calcic brown) and infertile (lithic) soils. Inherent plant growth rates were determined by growing young plants of all species on both soil types in a greenhouse. Plants were fertilized with NPK (150 or 300 kg/ha) and watered to field capacity. Urea ((NH2)2CO),diammonium phosphate ( NH4)2 Po4 and KCL were used as sources of fertilizer. On fertile soils, Mimosa had the highest inherent growth rate, followed by Auxemma, Croton, and Caesalpinia. In pen and field trials, Mimosa was preferred by goats, followed by Auxemma, Croton, and Caesalpinia. Results were similar on infertile soils, but Croton had a higher growth rate than Auxemma, and Croton was preferred to Auxemma by goats . Fertilization with 150 or 300 kg/ha of NPK increased palatability of coppice of all plant species to goats on both fertile (non-calcic brown) and infertile (lithic) soils.
Fertilization affected the chemical and physical characteristics of the four plant species. Concentrations of tannins and lignins decreased as did leaf toughness, while nitrogen, phosphorus, and calcium increased. In vitro organic matter and neutral detergent fiber digestibilities did not change. The prediction that fertilized plants would be lower in carbon based compounds than the unfertilized plants was supported by the results of my study.

description: The behaviour and fate of tissue cells is controlled by the rigidity and geometry of their adhesive environment, possibly through forces localized to sites of adhesion. We introduce a mechanical model that predicts cellular force distributions for cells adhering to adhesive patterns with different geometries and rigidities. For continuous adhesion along a closed contour, forces are predicted to be localized to the corners. For discrete sites of adhesion, the model predicts the forces to be mainly determined by the lateral pull of the cell contour. With increasing distance between two neighboring sites of adhesion, the adhesion force increases because cell shape results in steeper pulling directions. Softer substrates result in smaller forces. Our predictions agree well with experimental force patterns measured on pillar assays.

title: Inter-Seasonal Range Relationships of Spanish Goats and Mule Deer in a Utah Oakbrush Community
Creators: name: Riggs, Robert Alexander
Publisher: name: Utah State University
Year: 1988

description: Three experiments were conducted to assess the potential for using Spanish goats to manage Gambel oakbrush winter range, dominated by Gambel oak (Quercus gambelii), for mule deer (Odocoileus hemionus). Summer- time food selection of goats, effects on plant community composition, and consequent effects on mule deer nutrition and foraging behavior were examined.
An apparent preference for juvenile oak browse, and low use of oak twigs was observed. Selection for juvenile browse may have been facilitated by the retarded phenology of oak as compared to that of associated flora. This differential was maintained by repeated browsing. Animal performance, reflected in mass-specific gain rates, varied markedly. However, poor performance when observed, was not correlated with high juvenile oak content in diets.
Goat browsing did not affect density of any shrub species. Stem size distributions changed in browsed oak populations only; skewness of these increased over time because of sprouting. Sprout weights increased in browsed oak populations, but declined in comparably browsed serviceberry (Amelanchier alnifolia) populations. The only other significant sprout response was a numerical increase in browsed snowberry (Symphoricarpos oreophilus) populations. Relationships between stem size and stem productivity in heavily browsed oak and serviceberry were characterized by lower slopes than those for adjacent control populations. Conversely, relationships in rabbitbrush (Chrvsothamnus viscidiflorus) populations, which were little used, were characterized by higher slopes than those for adjacent control populations. Sagebrush (Artemisia tridentata wvominqensis) production also responded positively, but via increased intercept. Browsing reduced productivity of both serviceberry and oak, but enhanced that of sagebrush. A positive production response was suggested for herbaceous species.
Forage-base changes induced by goats caused wintering deer to increase the proportion of sagebrush in their diets under snow-covered conditions but not under snow-free conditions. Under snow-covered conditions, deer using goat-browsed pastures consumed diets higher in dry matter digestibility, but not protein, than those consumed by deer in control pastures. Dietary quality was unaffected by prior goat browsing under snow- free conditions. Furthermore, quality of diets consumed under snow-free conditions was not better than that consumed under snow-covered conditions.
On Wigner functions and a damped star product in dissipative phase-space quantum mechanics

description: Dito and Turrubiates recently introduced an interesting model of the dissipative quantum mechanics of a damped harmonic oscillator in phase space. Its key ingredient is a non-Hermitian deformation of the Moyal star product with the damping constant as deformation parameter. We compare the Dito-Turrubiates scheme with phase-space quantum mechanics (or deformation quantization) based on other star products, and extend it to incorporate Wigner functions. The deformed (or damped) star product is related to a complex Hamiltonian, and so necessitates a modified equation of motion involving complex conjugation. We find that with this change the Wigner function satisfies the classical equation of motion. This seems appropriate since non-dissipative systems with quadratic Hamiltonians share this property.

title: The Behavioral Responses of Utah Prairie Dogs (Cynomys parvidens) to Translocation
Creators: name: Ackers, Steven H.
Publisher: name: Utah State University
Year: 1992

description: In cases where refuge acquisition or captive breeding programs are not practical or justifiable, wild caught animals are frequently translocated into areas of suitable habitat. Such management programs seldom are designed to account for the behavioral responses of translocated animals to an unfamiliar habitat, breakup of social units, and/or interactions with existing social units in the new habitat. Ongoing efforts to translocate threatened Utah prairie dogs (Cynomys parvidens) from areas where conflicts with other land uses are occurring to public land sites have met with limited success. This could be due, in part, to behavioral responses associated with disrupting social units and placing animals in an unfamiliar environment.
The purpose of this research was to test a series of hypotheses regarding the behavioral responses of Utah prairie dogs to translocation. Focal animal sampling was used to estimate the durations and frequencies of five behavioral variables and five interaction types at four treatments: control, new site, supplemental site, and new population. In Chapter 1, activity budgets were compared among control animals, animals released into a new site versus a supplemental site, and animals already present at a supplemental site. The objective was to evaluate the relative effects of new and supplemental translocations and the effects of translocations on resident animals. In Chapter 2, the frequencies of interactions were compared among these same treatments to evaluate the effects of translocation on the sociality of Utah prairie dogs as reflected by changes in the frequencies of greeting displays, dominance/subordinance displays, and amicable and agonistic interactions. Chapter 3 compares the activity budgets of animals released at a site containing natural burrows (i.e., new population) and animals released into a site containing artificial burrows (i.e., new site) to a control. Habitat measurements for these treatments were also compared to evaluate the importance of habitat characteristics typical of prairie dog colonies to translocated animals. Hotelling's T2 analyses were used to compare behavioral durations between treatments and log-linear analyses were use to compare behavioral frequencies among treatments. Activity budgets were altered by translocation through tradeoffs between the amount of time spent foraging, being vigilant, exploring the unfamiliar habitat, and minimizing conspicuousness. Predicted changes in interactions frequencies as a result of translocations were not observed.
Activity budgets of animals released into the site containing natural burrows did not differ from those of control animals . The most important behavioral consideration is the effects of burrow and habitat characteristics in providing centers of activity and effective predator detection and avoidance.

description: Functional connectivity (FC) studies have demonstrated the overarching value of studying the brain and its disorders through the undirected weighted graph of fMRI correlation matrix. Most of the work with the FC, however, depends on the way the connectivity is computed, and further depends on the manual post-hoc analysis of the FC matrices. In this work we propose a deep learning architecture BrainGNN that learns the connectivity structure as part of learning to classify subjects. It simultaneously applies a graphical neural network to this learned graph and learns to select a sparse subset of brain regions important to the prediction task. We demonstrate the model's state-of-the-art classification performance on a schizophrenia fMRI dataset and demonstrate how introspection leads to disorder relevant findings. The graphs learned by the model exhibit strong class discrimination and the sparse subset of relevant regions are consistent with the schizophrenia literature.

title: Comparative Economics of Cattle and Wildlife Ranching in the Zimbabwe Midlands
Creators: name: Kreuter, Urs P.
Publisher: name: Utah State University
Year: 1992

description: The economics of ranches in the Zimbabwe Midlands, generating income from cattle, or wildlife, or both, were compared during 1989/90 to test the claim that wildlife ranching can generate greater profits than cattle ranching on semi-arid African savannas. Both financial (market) prices and economic prices (opportunity cost) were used.
Financial data were obtained from 15 cattle, 7 wildlife and 13 mixed ranches in four areas with wildlife and from 15 cattle ranches in two areas with sparse wildlife. Estimates of economic prices were obtained from official data.
In the first paper, gross revenues, costs, net revenues, and capital investments of each ranch type were compared. Cattle ranches in the areas with sparse wildlife provided the greatest net revenues while only mixed ranches were financially profitable in areas with abundant wildlife. Wildlife ranches had the least capital investments.
In the second paper a policy analysis matrix was used to compare financial and economic profitability. Excluding policy interventions, cattle ranches in areas with sparse wildlife were most profitable. Negative financial-economic profit differences showed that all ranchers faced production disincentives, but cattle ranchers were affected the most.
In the third paper an attempt was made to quantify the cost of lost rangeland productivity due to overstocking. Carrying capacities and stocking rates were estimated and a range of overstocking costs was used. Cattle ranches appeared to be overstocked while wildlife ranches were not. Thus the larger economic profit of cattle versus wildlife ranches decreased when range productivity loss increased.
The last paper compared the relative efficiency of cattle, wildlife, and mixed ranches from the financial perspective (using the private cost ratio) and from the national perspective (using the domestic resource cost). While few ranches were financially efficient, cattle ranches with sparse wildlife and mixed and wildlife operations were found to be economically efficient when overstocking costs were not charged. With increased rangeland sensitivity to overstocking, the probability of economic inefficiency increased more for cattle than mixed or wildlife ranches.
This study did not corroborate the claim that wildlife ranching is more profitable or efficient than cattle ranching in semi-arid African savannas.

description: Quantum cosmology offers a unique stage to address questions of time related to its underlying (and perhaps truly quantum dynamical) meaning as well as its origin. Some of these issues can be analyzed with a general scheme of quantum cosmology, others are best seen in loop quantum cosmology. The latter's status is still incomplete, and so no full scenario has yet emerged. Nevertheless, using properties that have a potential of pervading more complicated and realistic models, a vague picture shall be sketched here. It suggests the possibility of deriving a beginning within a beginningless theory, by applying cosmic forgetfulness to an early history of the universe.

description: With the development of quantum computing, the use of quantum algorithms to solve combinatorial optimization problems on quantum computers has become a major research focus. The Quadratic Unconstrained Binary Optimization (QUBO) model serves as a bridge between combinatorial optimization problems and quantum computers, and is a prerequisite for these studies. In combinatorial optimization problems, the Domination Problem (DP) is related to many practical issues in the real world, such as the fire station problem, social network theory, and so on. Additionally, the DP has numerous variants, such as independent DP, total DP, k-domination, and so forth. However, there is a scarcity of quantum computing research on these variant problems. A possible reason for this is the lack of research on QUBO modeling for these issues. This paper investigates the QUBO modeling methods for the classic DP and its variants. Compared to previous studies, the QUBO modeling method we propose for the classic DP can utilize fewer qubits. This will lower the barrier for solving DP on quantum computers. At the same time, for many variants of DP problems, we provide their QUBO modeling methods for the first time. Our work will accelerate the entry of DP into the quantum era.

description: In this work, we describe a computational framework for the genome-wide identification and characterization of mixed transcriptional/post-transcriptional regulatory circuits in humans. We concentrated in particular on feed-forward loops (FFL), in which a master transcription factor regulates a microRNA, and together with it, a set of joint target protein coding genes. The circuits were assembled with a two step procedure. We first constructed separately the transcriptional and post-transcriptional components of the human regulatory network by looking for conserved over-represented motifs in human and mouse promoters, and 3'-UTRs. Then, we combined the two subnetworks looking for mixed feed-forward regulatory interactions, finding a total of 638 putative (merged) FFLs. In order to investigate their biological relevance, we filtered these circuits using three selection criteria: (I) GeneOntology enrichment among the joint targets of the FFL, (II) independent computational evidence for the regulatory interactions of the FFL, extracted from external databases, and (III) relevance of the FFL in cancer. Most of the selected FFLs seem to be involved in various aspects of organism development and differentiation. We finally discuss a few of the most interesting cases in detail.

description: Chronic political instability and erratic economic management in most African countries since the implementation of self-rule in the 1950s has produced a record of persistent economic decline. This general problem of stalled African development has been linked to poor governance, a key proposed solution being political, administrative and/or financial decentralisation to empower communities to foster local economic development (LED). This thesis investigates the effectiveness of the decentralised governance approach. Combining a qualitative social science approach with the Participatory Action Research (PAR) methodology, the study analyses the experience of decentralisation in two Ugandan communities from the perspective of those directly affected by it. Through PAR, it aimed to empower local government officials to obtain better outcomes for their communities by adopting a cycle of planning, action and reflection on the structure and operation of decentralisation policies and procedures. The research methods employed also included literature review of decentralised governance in pre- and post-colonial Uganda and content analysis of governmental and non-governmental organisation documents, supported by interviews, council meetings, and workshops with local governmental officials, with observation of local government practices. The study found that decentralisation as currently practiced leads to the disempowerment of local leaders via a lack of accountability, transparency, participation, financial systems practices, money-politics and alleged corruption, and deferential cultural orientations. However, the thesis also demonstrates how, through PAR, these decentralisation challenges were significantly reduced through gradual and continued conscientisation of local government officials via collective, community learning. The significance of the study lies in its highlighting the large gap between theories of decentralised local governance and on-the-ground practices.
title: Density-Dependent Convective Flow in Closed Basins

description: The Great Basin is a region of the Basin and Range Physiographic Province, which is completely isolated hydrologically from the sea. All precipitation that falls within the Great Basin is lost from the land surface or from the surf ace of closed inland lakes through evapotranspiration. Playas are often found at the base of these undrained basins. This study focuses on subsurface groundwater flow patterns in closed basins. Because all discharge from the basins occurs via evapotranspiration on and near the playa, the water table of the aquifer beneath the playa is often just below the ground surface. Fluctuations of the water table due to climatic events cause the water table to rise and dissolve the salts on the playa surface. This mass transfer can produce density gradients that in turn cause flow.
This study is an extension of the work performed by Duffy and Al-Hassan (Duffy and Al-Hassan 1988) in which numerical experiments were used to show that the free convection, caused by the variation in density of the bulk fluid propenies, appears to play an important role in determining the patterns of groundwater flow beneath the playa. Their work considered only homogeneous, isotropic porous media in symmetric basins. The effects of anisotropy, periodic stratification, and asymmetric basins on the groundwater flow and transport patterns was studied here. Dimensionless parameters, the Rayleigh number and the salt nose length, L0*, were defined for each of the systems incorporated and were shown to be linearly related. The implication of this relationship is that the Rayleigh number can be used to predict basin-scale circulation patterns in the hypothetical closed basins studied. It was also determined that an equivalent anisotropic system could be defined for a horizontally stratified aquifer in order to predict basin-scale circulation patterns. An equivalent isotropic system was defined for each anisotropic system in a similar manner.

description: The following is a study of the problem of computer generation of non-isomorphic regular graphs of degree d on n points. The uork consists of a study of various properties and representations of regular graphs and a discussion of hov these might be useful in solving the isomorphism problem in the computer generation of regular graphs. An algorithm for the generation of regular graphs of degree 3 on n points with a Hamiltonian cycle is presented. The algorithm is not ideal in that it does not generate distinct (ie. non-isomorphic) copies, and so a procedure for detecting graph isomorphism is used to process the list of graphs produced by the algorithm.

description: Gamma-ray Bursts (GRBs) are among the potential extragalactic sources of very-high-energy (VHE) gamma-rays. We discuss the prospects of detecting VHE gamma-rays with current ground-based Cherenkov instruments during the afterglow phase. Using the fireball model, we calculate the synchrotron self-Compton (SSC) emission from forward-shock electrons. The modeled results are compared with the observational afterglow data taken with and/or the sensitivity level of ground-based VHE instruments (e.g. STACEE, H.E.S.S., MAGIC, VERITAS, and Whipple). We find that modeled SSC emission from bright and nearby bursts such as GRB 030329 are detectable by these instruments even with a delayed observation time of ~10 hours.

description: Ascorbic acid (AA) determination is of high importance in the diagnosis and treatment of diseases. Herein, we report a new ratiometric electrochemical sensor for ascorbic acid using a glassy carbon electrode (GCE) modified with a copper nanoparticle@resin nanosphere nanocomposite (CuNPs@RNS). The ratiometric strategy was established by immobilizing an internal reference (thionine) on the modified electrode using cyclic voltammetry (CV). The performance of the modified electrodes as well as the newly established ratiometric strategy was explored. The sensing platform had good electrocatalytic ability, reproducibility, and stability. In addition, the ratiometric strategy significantly improved the performance of electrochemical sensing with a wide linear range (0.0837 to 15.5 μM) and a low detection limit of 0.0279 μM under the optimal conditions. The original ratiometric electrochemical sensor was successfully applied to monitor ascorbic acid in tablets and urine. These results showed that the sensor provides a new strategy and broad prospects for biomolecular sensing with reliability and high sensitivity.

title: Optimization of Ranch Management Alternatives in Utah

description: The purpose of this study was to determine the optimum combination of various cattle production, range forage, and crop harvesting alternatives available to ranch owners and managers in Utah. While many promising alternatives are available, determining which alternatives to implement is difficult because the total ranch operation must be considered.
Linear programming (LP) is a tool available to ranch managers which allows the profit maximizing combination of improvements to be easily determined. LP allows ranchers to examine the entire ranch operation and to reduce the amount of risk and uncertainty involved in the decision making process.
The typical Utah ranch operation was described from a sample of 96 Utah ranches. Sixteen potential cattle options, 11 range forage options, and 3 crop options were developed to improve net variable cash ranch income of the typical Utah ranch. An LP model was developed to determine the optimum combination and level of options, the most efficient options, and the limiting constraints. Four scenarios based on range site and bush infestation type were compared to add flexibility to the model.
The optimal solution ran 266 brood cows under the O'Connor Management System (cows in moderate body condition at calving, 60-day calving season, 48-hour calf removal, cows gaining weight for 5 weeks starting 2 weeks before breeding season, and cows bred to fertile bulls) compared to 196 brood cows under the typical situation. In all optimization runs, burning big sage brush (artemesia tridentata) or pinyon-juniper (Pinus - Juniperus) infestations on crested wheatgrass (Agropyron desertorum) foothill ranges was the most economically efficient range forage option. The most economically efficient crop option was the combination of grazing the grass hayfields and custom harvesting the alfalfa hayfields. It was necessary to construct stock water ponds and properly distribute salt to increase summer forage availability. The optimum combination of improvements required 808 hours of hired labor. The net variable cash ranch income after burning sagebrush or pinyon-juniper types was $56,145 and $55,861, respectively compared to $31,278 for the typical Utah cow-calf operation. The optimal solution will change as input and product prices change. The model was not designed to make general recommendations but to be applied to specific ranching operations.
