description: Covid-19 has had a big impact on many aspects of our life including mental health. Since the start of the pandemic, a whole body of research has been performed on the relation between covid-19 and mental health (care). The mental health & covid-19 working group of the Superior Health Council has kept track of this research and the Belgian data on mental health (care), in order to formulate recommendations on the management of the mental health (care) impact of covid-19. (cf. living document I and II). Within this living document, the superior health council maps the recommendations on the management of the mental health (care) impact of covid-19 formulated by the Superior Health Council and compares this mapping with the policy initiatives which have already been undertaken and/or planned by the Belgian government and federated entities. This will allow us to monitor investment on mental health (care) by the Belgian government and federated entities during this covid-19 pandemic, but also facilitate the identification of potentially remaining gaps in order to further formulated recommendations. This document will be updated on a monthly basis.

Mossbauer investigation of Fe 57 in Linde L Zeolite
Creators: name: Wedd, Robert William James
Publisher: name: University of British Columbia
Year: 2011

description: Two independent Fe³⁺ species have been simultaneously introduced into Linde L zeolite. One is an exchanged Fe³⁺ species while the other is the molecular species FeCI₃, By simpIe outgassing at 573°K, the exchanged Fe³⁺ is reduced to Fe²⁺. By sweeping the system at 523°K with H₂, both species are converted to ferrous and, at 573°K, the exchanged species is reduced to Feº and the FeCI₃ is reduced to FeCI₂. Outgassing the latter system at 573°K oxidizes the Feº to Fe₂O₃ while the FeCI₂ remains intact. These valency changes were examined using Mössbauer Spectroscopy and, using this technique, a Morin transition appears to have been detected in the Feº species.

description: Poles of integrale tritronquee are in bijection with cubic oscillators that admit the simultaneous solutions of two quantization conditions. We show that the poles lie near the solutions of a pair of Bohr-Sommerfeld quantization conditions (the Bohr-Sommerfeld-Boutroux system): the distance between a pole and the corresponding solution of the Bohr-Sommerfeld-Boutroux system vanishes asymptotically.

description: Neutron scattering measurements show the ferromagnetic XY pyrochlore Yb2Ti2O7 to display strong quasi-two dimensional (2D) spin correlations at low temperature, which give way to long range order (LRO) under the application of modest magnetic fields. Rods of scattering along < 111 > directions due to these 2D spin correlations imply a magnetic decomposition of the cubic pyrochlore system into decoupled kagome planes. A magnetic field of ~0.5 T applied along the [1-10] direction induces a transition to a 3D LRO state characterized by long-lived, dispersive spin waves. Our measurements map out a complex low temperature-field phase diagram for this exotic pyrochlore magnet.

description: The work carried out for this thesis examined the cardiovascular and antiinflammatory benefits of long chain omega-3 polyunsaturated fatty acids (LC n-3 PUFAs). LC n-3 PUFAs have blood pressure lowering, anti-inflammatory and antithrombotic effects, however their exact mechanisms of action are still unclear. This project aimed to elucidate these mechanisms, by using a human cell culture model of vascular inflammation, and through dietary supplementation of people with mild, chronic vascular inflammation with capsules containing LC n-3 PUFAs. Vascular function was examined by dietary supplementation of a mouse model of chronic inflammation with LC n-3 PUFAs. The pro-coagulant glycoprotein von Willebrand factor (vWF) was of particular interest as excessive release of vWF from the endothelium is linked to endothelial dysfunction that might contribute to the manifestation of clinical complications associated with cardiovascular disease. The main findings of these studies were that: 1) LC n-3 PUFAs modulated the release of vWF in some phorbol ester-stimulated human umbilical vein endothelial cells by preventing actin cytoskeleton rearrangement. 2) Dietary supplementation of mildly hypertensive subjects with LC n-3 PUFAs increased incorporation of LC n-3 PUFAs into cell membrane phospholipids, without altering plasma vWF profile. 3) Dietary supplementation of a mouse model of abdominal aortic aneurysm with LC n-3 PUFAs prevented an increase in arterial blood pressure without affecting vascular reactivity. Collectively these findings highlight a novel mechanism of action of the LC n-3 PUFAs and suggest them as a potential adjunct treatment option for vascular inflammatory disease.

description: We study the dynamics of a non-minimally coupled scalar field cosmology with a potential function. We use the framework of dynamical systems theory to investigate all evolutional paths admissible for all initial conditions. Additionally, we assume the presence of barotropic matter and show that the dynamics can be formulated in terms of an autonomous dynamical system. We have found fixed points corresponding to three main stages of the evolution of the universe, namely, radiation, matter and quintessence domination epochs. Using the linearization of the dynamical systems in the vicinity of the critical points we explicitly obtain formulas determining the effective equation of state parameter for the universe at different epochs. In our approach the form of $w(z)$ parametrisation is derived directly from the dynamical equations rather than postulated {\it a priori}.

description: Twisted magnetic fields are frequently seen to emerge above the visible surface of the Sun. This emergence is usually associated with the rise of buoyant magnetic flux structures. Here we ask how magnetic fields from a turbulent large-scale dynamo appear above the surface if there is no magnetic buoyancy. The computational domain is split into two parts. In the lower part, which we refer to as the turbulence zone, the flow is driven by an assumed helical forcing function leading to dynamo action. Above this region, which we refer to as the exterior, a nearly force-free magnetic field is computed at each time step using the stress-and-relax method. Twisted arcade-like field structures are found to emerge in the exterior above the turbulence zone. Strong current sheets tend to form above the neutral line, where the vertical field component vanishes. Time series of the magnetic field structure show recurrent plasmoid ejections. The degree to which the exterior field is force free is estimated as the ratio of the dot product of current density and magnetic field strength to their respective rms values. This ratio reaches values of up to 95% in the exterior. A weak outward flow is driven by the residual Lorentz force.

Year: 2016

description: The ability to create three-dimensional (3D) images offers a wide variety of solutions to meet ever increasing consumer demands. As popularity for 3D cinema and television continues to grow, 3D images will remain an important area of research and development. While there are a variety of ways to create a 3D model, textel images are quickly become the preferred solution that has been captured with a texel camera. The combination of multiple texel images taken around a scene can be used to form a texel model. Offering both visual and dimensional accuracy, texel models are becoming invaluable tools for disaster management, situational awareness, and even military application. However, displaying a texel model often provides challenges, and the problems that arise when viewing texel models will be discussed and corrected in this paper.
Twisted Covariance as a Non Invariant Restriction of the Fully Covariant DFR Model

description: We discuss twisted covariance over the noncommutative spacetime algebra generated by the relations [q_theta^mu,q_theta^nu]=i theta^{mu nu}, where the matrix theta is treated as fixed (not a tensor), and we refrain from using the asymptotic Moyal expansion of the twists. We show that the tensor nature of theta is only hidden in the formalism: in particular if theta fulfils the DFR conditions, the twisted Lorentz covariant model of the flat quantum spacetime may be equivalently described in terms of the DFR model, if we agree to discard a huge non invariant set of localisation states; it is only this last step which, if taken as a basic assumption, severely breaks the relativity principle. We also will show that the above mentioned, relativity breaking, ad hoc rejection of localisation states is an independent, unnecessary assumption, as far as some popular approaches to quantum field theory on the quantum Minkowski spacetime are concerned. The above should raise some concerns about speculations on possible observable consequences of arbitrary choices of theta in arbitrarily selected privileged frames.

description: The winged pearl oyster, Pteria penguin (Röding, 1798), is widely cultured for the production of high-quality mabé pearls (half-pearls) in the Kingdom of Tonga and the Pacific. Mabé pearl culture provides a sustainable, culturally appropriate income source to many remote coastal communities and supports a diverse range of pearl-based livelihoods. Mabé pearls are cultured by attaching hemispherical nuclei to the inner nacreous (mother-of-pearl) surfaces of pearl oyster shells. Successive layers of nacre are then deposited over the nuclei to produce mabé pearls of commercial nacre thickness within 9-12 months. The Kingdom of Tonga is the leading producer of mabé pearls in the south Pacific and has considerable potential for sector development and livelihood support. Despite this, optimal environmental and culture conditions for growth and mabé pearl production by P. penguin in Tonga are unknown. This paucity of information limits the production potential of the mabé pearl sector and its’ associated livelihood benefits to communities in Tonga and the Pacific.

description: A regional neural network-based method, “CANYON-MED” is developed to estimate nutrients and carbonate system variables specifically in the Mediterranean Sea over the water column from pressure, temperature, salinity, and oxygen together with geolocation and date of sampling. Six neural network ensembles were developed, one for each variable (i.e., three macronutrients: nitrates (NO−3), phosphates (PO3−4) and silicates (SiOH4), and three carbonate system variables: pH on the total scale (pHT),total alkalinity (AT), and dissolved inorganic carbon or total carbon (CT), trained using a specific quality-controlled dataset of reference “bottle” data in the MediterraneanSea. This dataset is representative of the peculiar conditions of this semi-enclosed sea, as opposed to the global ocean. For each variable, the neural networks were trained on 80% of the data chosen randomly and validated using the remaining 20%.CANYON-MED retrieved the variables with good accuracies (Root Mean Squared Error):0.73μmol.kg−1for NO−3, 0.045μmol.kg−1for PO3−4and 0.70μmol.kg−1for Si(OH)4,0.016 units for pHT, 11μmol.kg−1forATand 10μmol.kg−1forCT. A second validationon the ANTARES independent time series confirmed the method’s applicability in the Mediterranean Sea. After comparison to other existing methods to estimate nutrients and carbonate system variables, CANYON-MED stood out as the most robust, using the aforementioned inputs. The application of CANYON-MED on the MediterraneanSea data from autonomous observing systems (integrated network of Biogeochemical-Argo floats, Eulerian moorings and ocean gliders measuring hydrological propertiestogether with oxygen concentration) could have a wide range of applications. These include data quality control or filling gaps in time series, as well as biogeochemical data assimilation and/or the initialization and validation of regional biogeochemical models still lacking crucial reference data.

Publisher: name: Utah State University

description: Gorongosa: a history of an African landscape, 1921-2014, focuses on changes in the Gorongosa ecosystem, in central Mozambique, southeastern Africa. Environmental changes result from natural, non-human causes and from the activities of humans. I describe four socioecological events: African and Portuguese interactions, Gorongosa National Park, the effects of Mozambique’s civil war, and the Park's restoration in the aftermath of the civil war. Prior to European partition of Africa in 1884-85, Mozambique did not exist as clearly a demarcated territory as it is now. Today, the sense of Mozambicanhood bears traces of Portuguese colonial era experience. The demarcation of Mozambique’s boundaries and the reshaping of the colony until 1975 was a painful process that both the Africans and Portuguese colonialists endured; these physical and social separations from the rest of southern Africa represented the first human-induced changes in southern Africa. The endeavors to reshape Mozambique did not end with political boundaries. Painful processes, including the reshaping of Gorongosa National Park in the Gorongosa ecosystem, continued after border demarcations. Countless Mozambican and Portuguese lives were lost in the long trajectory within the colony as the Africans and the Europeans all developed a sense of unity in diversity while reshaping their attitude of and about Mozambique. After independence in 1975, internal transformations and wars continued reshaping Mozambique and Mozambicans, as different nationalists sought to maintain their colonial experience. These dynamics marked the environmental history of the Mozambican and Portuguese peoples and are often reflected in the prevalence of high sympathy, which the two peoples share toward one another. Gorongosa: a history of an African landscape, 1921-2014, critically celebrates these collective achievements.
title: Modeling Seed Dispersal and Population Migration Given a Distribution of Seed Handling Times and Variable Dispersal Motility: Case Study for Pinyon and Juniper in Utah
Creators: name: Neupane, Ram C.
Publisher: name: Utah State University
Year: 2015

description: The spread of fruiting tree species is strongly determined by the behavior and range of fruit-eating animals, particularly birds. Birds either consume and digest seeds or carry and cache them at some distance from the source tree. These carried and settled seeds provide some form of distribution which generates tree spread to the new location. Firstly, we modal seed dispersal by birds and introduce it in a dispersal model to estimate seed distribution. Using this distribution, we create a population model to estimate the speed at which juniper and pinyon forest boundaries move.
Secondly, we introduce a fact that bird movement occurs based on local habitat type to receive modified dispersal model. Birds can easily move many kilometers but habitat changes on the scale of tens of meters with rapidly varying. We develop a new technique to solve the modified dispersal model and approximate the form of transported seed distributions in highly variable landscapes. Using a tree population model, we investigate the rate of forest migration in variable landscapes. We show that speeds calculated using average motility of animals and mean seed handling times accurately predict the migration rate of trees.
Regional scale forest distribution models are frequently used to project tree migration based on climate and geographic variables such as elevation, and regional presence-absence data. It is difficult to accurately use dispersal models based on large-scale presence-absence data, particularly for tree species dispersed by birds. The challenge is that variables associated with seed dispersal by birds are represented only few meters while the smallest pixel size for the distribution models begins with few kilometers. Transported seed distribution estimated in the variable landscape offers a tool to make use of this scale separation. Finally, we develop a scenarios that allows us to find large scale dispersal probabilities based on small scale environmental variables.
title: The Effects of Unidirectional Peer Tutoring on Mathematics Outcomes for Students with Learning Disabilities in an Inclusive, Secondary Setting
Creators: name: Pyle, Daniel

Year: 2015

description: Students with disabilities included in general education settings often require varying levels of supports and services to execute classroom routines effectively while maximizing their learning opportunities. One support that holds potential to increase outcomes for students with disabilities in general education settings is peer tutoring. Therefore, the purpose of this study was to determine the effects that a targeted, unidirectional tutoring intervention had on the math outcomes for students with learning disabilities in a Secondary Mathematics I class. High school students that had advanced skills in mathematics served as interventionists (i.e., peer tutors) and were trained to deliver the unidirectional tutoring intervention to students with learning disabilities who were identified as low achievers in mathematics. All three tutees increased their criterion and normative (i.e., as compared to their peers) performance on teacher-developed weekly mathematics quizzes when receiving the tutoring intervention. Furthermore, all three tutees increased their quantity and quality of mathematics problems completed as well as academic engagement during the tutoring intervention. Finally, tutees, tutors, and a general education teacher indicated that they perceive the unidirectional tutoring intervention as effective and socially desirable.

description: Motivated by A. Z. Petrov's classification of four-dimensional Lorentzian metrics, we provide an algebraic classification of the isometry-isotropy pairs of four-dimensional pseudo-Riemannian metrics admitting local slices with five-dimensional isometries contained in the Lorentz algebra. A purely Lie algebraic approach is applied with emphasis on the use of Lie theoretic invariants to distinguish invariant algebra-subalgebra pairs. This method yields an algorithm for identifying isometry-isotropy pairs subject to the aforementioned constraints.

description: The objective of these oral histories was to examine, explain and reveal the success of a small group of Saudia (female Saudis) whose studies at a mid-Western American university through the medium of English (their second or third language). Four students were randomly selected from a group of volunteers, based on their successful completion of the English as a Second Language (ESL) program, plus a year of other academic classes in the university. One student, who had not completed the ESL program, was admitted to the master of English program having passed the Test of English as a Foreign Language (TOEFL) test at the required level.
The student participants were interviewed a number of times in the course of the study and after the completion of the writing to check the evidence. The interviews were semi-structured to allow the participants to expand as they desired. The data was analyzed using the theories of Islamic feminism and intersectionality to discover how the students were able to succeed in a profoundly different school and social culture as an English Language Learner (ELL) where many other ELLs fail to complete a degree program. Attention was focused on the participants explanations of their successes, failures and challenges.

description: The conchoid of a plane curve $C$ is constructed using a fixed circle $B$ in the affine plane. We generalize the classical definition so that we obtain a conchoid from any pair of curves $B$ and $C$ in the projective plane. We present two definitions, one purely algebraic through resultants and a more geometric one using an incidence correspondence in $\PP^2 \times \PP^2$. We prove, among other things, that the conchoid of a generic curve of fixed degree is irreducible, we determine its singularities and give a formula for its degree and genus. In the final section we return to the classical case: for any given curve $C$ we give a criterion for its conchoid to be irreducible and we give a procedure to determine when a curve is the conchoid of another.

description: The explosion of internet traffic, advent of social media sites such as Facebook and Twitter, and increased availability of digital cameras has saturated life with images and videos. Never before has it been so important to sift quickly through large amounts of digital information. Salient Object Detection (SOD) is a computer vision topic that finds methods to locate important objects in pictures. SOD has proven to be helpful in numerous applications such as image forgery detection and traffic sign recognition. In this thesis, I outline a novel SOD technique to automatically isolate important objects from the background in images.
title: Impact of Mass and Bond Energy Difference and Interface Defects on Thermal Boundary Conductance
Creators: name: Choi, ChangJin
Publisher: name: Utah State University
Year: 2016

description: Many portions of energy generated in the U.S. are not used and take the form of wasted heat due to a poor heat transfer efficiency. This fact leads research communities to focus on thermoelectrics as a means for using waste heat through direct thermal to electrical energy conversion. One way to enhance thermoelectric efficiency is to reduce thermal conductivity through nanostructuring. In nanostructures, understanding energy transport across the interface of two materials is important because interfaces dominate the resistance to overall thermal transport of the system and can be described by thermal boundary conductance (TBC). Also of note, an understanding of thermal transport cannot be achieved without an understanding of transfer via atomic vibration, known as phonons.
In this study, two different techniques of molecular dynamics (MD) simulation are introduced in order to improve the understanding of the phonon transport at the interface of dissimilar materials and the impact of different material properties on TBC. Non-equilibrium MD simulations are used to study relative and combined contributions of mass and bond energy difference on TBC and phonon wave-packet simulations are used to obtain a detailed description of phonon interactions at the interface. At the end of this study, a simple analytical model for the prediction of effective thermal conductivity, using knowledge of thermal boundary resistance, an inverse of TBC, and the interface geometry, is developed.
title: The Implementation of Interventions for Problem Behavior Based on the Results of Precursor Functional Analyses in the Early Childhood Setting
Creators: name: Halversen, Hayley
Publisher: name: Utah State University
Year: 2016

description: This study consisted of three parts. We first used a video observation method and statistical analysis to identify benign behaviors that occurred before the problem behavior. These benign behaviors are known as precursor behaviors. We then used a precursor functional analysis to identify the function of the precursor behaviors. Lastly, we developed and implemented an intervention based on the results of the precursor functional analysis. The interventions effectively reduced problem behavior for the participants in the study. The participants engaged in minimal instances of problem behavior throughout the study. The results of this study may be useful to teachers and caregivers of children who engage in severe problem behavior that would be unsafe to reinforce in an assessment. Results may also help when working with children whose caregivers are concerned with their children engaging in excessive problem behavior. Further research is needed to look at modifying the precursor analysis. Future research should also look at the social validity of the precursor assessment.
Power-enhanced multiple decision functions controlling family-wise error and false discovery rates

description: Improved procedures, in terms of smaller missed discovery rates (MDR), for performing multiple hypotheses testing with weak and strong control of the family-wise error rate (FWER) or the false discovery rate (FDR) are developed and studied. The improvement over existing procedures such as the Šidák procedure for FWER control and the Benjamini--Hochberg (BH) procedure for FDR control is achieved by exploiting possible differences in the powers of the individual tests. Results signal the need to take into account the powers of the individual tests and to have multiple hypotheses decision functions which are not limited to simply using the individual $p$-values, as is the case, for example, with the Šidák, Bonferroni, or BH procedures. They also enhance understanding of the role of the powers of individual tests, or more precisely the receiver operating characteristic (ROC) functions of decision processes, in the search for better multiple hypotheses testing procedures. A decision-theoretic framework is utilized, and through auxiliary randomizers the procedures could be used with discrete or mixed-type data or with rank-based nonparametric tests. This is in contrast to existing $p$-value based procedures whose theoretical validity is contingent on each of these $p$-value statistics being stochastically equal to or greater than a standard uniform variable under the null hypothesis. Proposed procedures are relevant in the analysis of high-dimensional "large $M$, small $n$" data sets arising in the natural, physical, medical, economic and social sciences, whose generation and creation is accelerated by advances in high-throughput technology, notably, but not limited to, microarray technology.

description: We investigate the mixed diamond chain composed of spins 1 and 1/2 when the exchange interaction is alternatingly distorted. Depending on the strengths of frustration and distortion, this system has various ground states. Each ground state consists of an array of spin clusters separated by singlet dimers by virtue of an infinite number of local conservation laws. We determine the ground state phase diagram by numerically analyzing each spin cluster. In particular for strong distortion, we find an infinite series of quantum phase transitions by the cluster expansion method and conformal field theory. This leads to the infinite series of steps in the behavior of the Curie constant and residual entropy.

description: We study the biased diffusion of particles moving in one direction under the action of a constant force in the presence of a piecewise linear random potential. Using the overdamped equation of motion, we represent the first and second moments of the particle position as inverse Laplace transforms. By applying to these transforms the ordinary and the modified Tauberian theorem, we determine the short- and long-time behavior of the mean-square displacement of particles. Our results show that while at short times the biased diffusion is always ballistic, at long times it can be either normal or anomalous. We formulate the conditions for normal and anomalous behavior and derive the laws of biased diffusion in both these cases.

description: The latest results of an ongoing project for the lattice simulation of QCD with a single quark flavor are presented. The Symanzik tree-level-improved Wilson action is adopted in the gauge sector and the (unimproved) Wilson action for the fermion. Results from new simulations with one step of Stout-smearing (rho=0.15) in the fermion action are discussed. The one-flavor theory is simulated by a polynomial hybrid Monte Carlo algorithm (PHMC) at beta=4.0 corresponding to a = 0.13fm, on 16^3x32 and 24^3x48 lattices; the box-size is L = 2.1fm and L = 3.1fm, respectively. At the lightest simulated quark mass the (partially quenched) pion mass is ~300 MeV. The masses of the lightest bound states are computed, including the flavor singlet scalar and pseudoscalar mesons sigma_s and eta_s, the scalar glueball 0^++, and the Delta^++ baryon. Relics of SUSY in the mass spectrum, expected from a large N_c orientifold equivalence with the N=1 supersymmetric Yang-Mills theory, are discussed.

description: This study was an extension of a study submitted in April 2014 by Sheldon D. Holt entitled “Ambient Temperature, Calf Intakes, and Weight Gains on Preweaned Dairy Calves”.
A major component in a profitable dairy operation is the raising of female calves as replacement heifers; but since no direct income is generated by calf raising alone, it is often overlooked as a potential profit area on a dairy farm. Calf management practices that ultimately impact milk productivity and reproductive performance during a heifer’s lifetime begin at birth. This study examines the effect of calf starter intake on calf growth, measuring specifically calf weight. How calf starter intake affected production costs was also examined. Other factors included in the study were seasonal change, hip height, days since birth, and weather conditions.
The cost of calf starter is one of the main contributors to total production cost in raising dairy calves. Since the amount of starter intake consumed by the calves in this study was measured by Holt, a cost analysis can be performed using these data. Therefore, the first two objectives of this study are to 1) develop a model which minimizes cost of starter feed (which is a variable controlled by the dairy producer) and 2) use the model developed under objective 1) to find the breakeven point (where the cost of an input is less than or equal to the value gained from that input) and conduct sensitivity analysis with respect to this point.
Although an analysis was performed on the data at the close of its collection in 2014 by S.D Holt, there are several econometric issues that were not adequately addressed before these analyses were performed. The following problems have been found in the data: functional form, multicollinearity, heteroskedasticity, and serial correlation. Any interpretation or prediction based on these data, without these issues being resolved, is not reliable. In order for interpretations and predictions based on these data to be valid, the last two objectives of this study are to 3) define in detail the econometric problems that existed in Holt’s study and 4) find and implement solutions to econometric problems that existed in that study.

description: In many irrigation systems and networks, there are multiple water users and shareholders who take their water from different locations along a single canal or pipeline. Often, irrigation splitter boxes are used to divert water to multiple shareholders from a single location. The splitter boxes, which can be small and compact, are generally installed at different locations along a piped irrigation supply line. The purpose of a splitter box is to split a specific amount of water so that each user receives their allotted portion, regardless of the flow rate in the system.
Each splitter box usually includes two compartments, separated by a wall that acts as a weir for the water to flow over. The water in the supply pipe enters the box and fills the upstream compartment until it spills over the weir. As water flows over the weir, it is separated by vertical dividers. Each divider is positioned to split a certain percentage of the total flow to one of the outlet pipes, which carry the water to various destinations. In general, splitter boxes perform very well at lower flow rates. However, if high flow rates are present in the box, due to under-design of the box or for any reason, the water surface becomes turbulent and the flow profile over the weir becomes disturbed and nonuniform. Because of these conditions, the flow becomes unevenly distributed and an accurate flow split cannot be achieved.
This study focuses on developing a solution that can be installed in flow splitter boxes to effectively dissipate energy and uniformly distribute the flow across the length of the weir during times of high flow rates.

description: The astronomical observations indicate that the universe expands with acceleration and it has a finite event horizon. The recent CMB observations confirm the universe is homogeneous, isotropic and asymptotically flat. The total gravitational energy of a body having mass m is the gravitational potential energy originating from the gravitational interaction of the body with all masses of the universe, within the event horizon. The flat geometry of the universe enables to determine the total gravitational energy of the mass m within the framework of the Newtonian gravity in Euclidean space. By this approach, it has been found the modulus of the total gravitational energy of a body is close to its rest energy E = m*c^2, which is a remarkable result. Besides, the smoothed gravitational potential in an arbitrary point of the observable universe appears close to - c^2, where c is the speed of the light.

title: An Analysis of the Feasibility of Anaerobic Digestion on Small-Scale Dairies in Utah

description: With an ever increasing concern for the environment, different methods of managing organic waste on dairy farms have been explored and analyzed. Anaerobic digestion has long been a popular method of managing organic waste. Its popularity stems from the potential to decrease greenhouse gases, improve air quality and provide a source of additional revenue for the farm. Problems with implementing anaerobic digestion arise from high failure rates, high start-up costs and continuous maintenance and equipment replacement.
Subsidies for the initial investment and improved technology have increased the possibility of large-scale dairy farms to adopt anaerobic digestion. Due to economies of scale large-scale dairy farms are more able to adopt anaerobic digestion, but small-scale dairies struggle to finance the investment, maintain the digester system and provide sufficient organic waste to continuously feed the microorganisms inside the digester system. The increasing impact of urbanization greatly impacts the demand for anaerobic digestion on small-scale farms to mitigate the negative effects of organic waste produced by dairy farms.
Dr. Conly Hansen at Utah State University suggested we use an IBR digester model to analyze the feasibility of adopting anaerobic digestion on small-scale farms. The IBR digester system is more conducive to small-scale dairies located in regions with varying temperature (i.e., Utah), and may be the solution to mitigate the negative effects of organic farm waste. Dr. Donald McMahon also suggested we analyze the potential of implementing a digester on a dairy farm that produces artisan cheese. We predicted that this would improve the feasibility due to the need to dispose of whey from the cheese production.
To determine the feasibility of implementing a digester system on a small-scale dairy farm the net present value and the internal rate of return were calculated to estimate the success of the investment. These financial measures were calculated from equipment price quotes, estimations from the literature review and from using estimated annual receipts and costs for a dairy farm, artisan cheese plant and anaerobic digester system. The feasibility also depends on the success of marketing the products produced from the digester system and the farmer’s participation in incentive programs for digester systems. The products produced vary from electricity to waste disposal services, and marketing an array of diverse products and services is important to the success of the digester system. The feasibility determined by this study was estimated using generalized assumptions from various sources and should be analyzed by individual operations to determine specific farm feasibility.
title: Immunologic, Hematologic, and Endocrine Responses to Subacute and Subchronic Exposures to Graded, Subanesthetic Levels of Nitrous Oxide in CD-1 Mice

description: Nitrous oxide (N2O) oxidizes vitamin B12. disrupting deoxyribonucleic acid (DNA) synthesis. Occupational exposures to subanesthetic levels of the gas have been documented that may result in suppressed proliferative cell activities. Male CD-I mice were exposed to 0, 50, 500, and 5000 parts of N2O per million parts of air (ppm) for 6 hr/day, 5 days/week for 2 and 13 weeks. Splenic lymphocytes were assayed for responsiveness to mitogens and for the ability to produce interleukin-2 (lL-2) . Tritiated-thymidine ([3H]-TdR) uptake was measured in CD-I splenic lymphocytes cultured in a mixed-lymphocyte culture (MLC). Cytolytic cell activity was measured by 51chromium release assay. Antibody-mediated immunocompetency was determined for sheep red blood cell (SRBC)-sensitized animals by plaque-forming cell (PFC) assay and sera anti-SRBC antibody titer. Deoxyuridine suppression tests (dUdRST) were performed on bone marrow cells. Serum adrenocorticotropic hormone and corticosterone levels were determined. There was significantly decreased splenic lymphocyte uptake of [3H)-TdR by cells cultured with mitogenic substances and in MLC following 2-week animal exposures to 5000 ppm. After 13-week exposures, the animals' splenic lymphocytes showed decreased [3H]-TdR uptake following low N20 dosing and nonsignificantly increased responsiveness at the higher gas exposures in both the blastogenic and MLC assays. Compared to control animals, the 5000- ppm-exposure group had significantly depressed PFC activity and circulating anti-SRBC immunoglobulin M levels following 13-week gas exposures, and all three subchronic exposure groups demonstrated both decreased liver weights and leukopenia. Bone marrow activity at these dosing levels was dose-responsively depressed following subchronic gas exposures.No hormonal effect appears to be attributable to N20 exposure.

description: The recent discovery of continuous tree-ring series starting as early as 1030 CE has for the first time made possible the reconstruction of historical climates for much of mainland Southeast Asia. Perhaps the most dramatic finding is that wide cyclic fluctuations in the reach and volume of monsoon rains contributed substantially to both the genesis and the collapse of the charter civilizations of Angkor, Pagan, and Dai Viet. From circa 1450–1820 climate continued to influence political and economic development, but its impact appears to have diminished both because the amplitude of hydrological fluctuations decreased markedly, and because new sources of power rendered early modern Southeast Asian states more resilient. A pioneering collaborative effort by a historian and a paleoclimatologist, this paper promises three benefits: It can help to solve a variety of local historiographic puzzles, it can facilitate construction of a synchronized historical narrative for mainland Southeast Asia as a whole, and it can aid comparisons between mainland Southeast Asia and other sectors of Eurasia.
