Necropsy Procedure for Cattle
Creators: name: Edwards, Alvin J.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1989

description: The key to disease control is the diagnosis. While history and clinical signs, possibly supplemented by laboratory tests, may lead to the diagnosis, it is often only the post mortem examination which can determine the nature of an animal's disease. Necropsies should therefore be regarded as standard diagnostic procedure, particularly in the case of herd problems. A skillfully conducted and intelligently interpreted post mortem examination will always give the stock owner a surprisingly high degree of satisfaction and will greatly enhance his confidence in the veterinarian. The performance of a necropsy is both a science and an art. As a science, it requires a thorough knowledge of general and special pathology of organs and organ systems. It assumes a familiarity with the infections, metabolic and parasitic diseases of different species. It demands the ability to recognize normal and pathological tissues with or without post mortem changes. As an art, it requires facility in standardized necropsy procedure to effectively illuminate pathological conditions so they may be studied accurately. It necessitates a concern for precision, neatness, and thoroughness so that a complete diagnosis can follow. The necropsy examination looks easy when one watches an experienced prospector at work. Familiarity and repeated use of a procedure increases proficiency and dispels the useless pulling, cutting, and destruction of lesions which greatly reduce the possibility of arriving at a diagnosis. The veterinarian who learns and adheres to a definite necropsy protocol will be uniform, rapid, systematic, and complete. Completeness facilitates diagnosis, or problem solving of cases, and is the key to consistent interpretation of lesions. Following a standard protocol assures that each organ system will be grossly observed in turn. Short cuts lead to a lack of thoroughness and a consequent missed diagnosis, or no diagnosis at all.

description: Context. Precise stellar parameters are crucial in exoplanet research for correctly determining of the planetary parameters. For stars hosting a transiting planet, determining of the planetary mass and radius depends on the stellar mass and radius, which in turn depend on the atmospheric stellar parameters. Different methods can provide different results, which leads to different planet characteristics.}%Spectroscopic surface gravities have shown to be poorly constrained, but the photometry of the transiting planet can provide an independent measurement of the surface gravity. Aims. In this paper, we use a uniform method to spectroscopically derive stellar atmospheric parameters, chemical abundances, stellar masses, and stellar radii for a sample of 90 transit hosts. Surface gravities are also derived photometrically using the stellar density as derived from the light curve. We study the effect of using these different surface gravities on the determination of the chemical abundances and the stellar mass and radius. Methods. A spectroscopic analysis based on Kurucz models in LTE was performed through the MOOG code to derive the atmospheric parameters and the chemical abundances. The photometric surface gravity was determined through isochrone fitting and the use of the stellar density, directly determined from the light curve. Stellar masses and radii are determined through calibration formulae. Results. Spectroscopic and photometric surface gravities differ, but this has very little effect on the precise determination of the stellar mass in our spectroscopic analysis. The stellar radius, and hence the planetary radius, is most affected by the surface gravity discrepancies. For the chemical abundances, the difference is, as expected, only noticable for the abundances derived from analyzing of lines of ionized species.

Anthelmintic Usage in Feedlot Cattle
Creators: name: Cheney, John M.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1989

description: Cattle feeding in the United States has changed dramatically over the past two decades. In the past, most of the cattle were fed by farmer-feeders in lots with less than 1000 head capacity. Today the majority of cattle fed are in much larger lots. Colorado feedlots last year fed approximately 2.4 million head of cattle and about one half of these were fed in lots with a capacity of over 32,000 head. All indications today point to this trend continuing with more and more cattle being fed in larger lots. As these lots have become larger, management practices have also changed. Cattle feeders are no longer farmers and cowboys, rather they are businessmen who know the entire cattle industry. As the cattle feeding industry has changed, so has the role of the feedlot veterinarian. The veterinarian is no longer asked to vaccinate, dehom, castrate or even treat most sick animals in the feedlot. The role of the feedlot veterinarian today is to advise and consult the feedlot operator. To do this effectively, the veterinarian must also understand the entire cattle industry and give economically sound advice to management. Part of that advice is an internal parasite control program which does not cost the producer but rather makes money for him. It may not sound like much when you figure it only costs $1.50 to $3.00 to worm a 700 pound steer, but when you worm 30,000 animals and the cost is $45,000 to $90,000 you talk real money. This brings me to the title of this paper: To Worm or Not To Worm.

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1989

description: Within the scientific and academic community there have been great accomplishments in understanding the epidemiology and pathogenesis of cattle diseases. Even so, the food animal industry continues to suffer significant monetary losses from disease pathogens and non-infectious disease disorders. As practicing veterinarians, our knowledge is limited only because of our inability to keep pace with the various disciplines within the scientific community. The area of biochemistry and cellular physiology, once thought to be subjects limited to the classroom, may hold the answer to improving the basis of effective and profitable herd health programs. Many livestock disease situations are a result of multifactorial health damaging situations that revolve around environment, area of origin, genetics, disease exposure, nutrition and agricultural practices. More significant in our industry is the highly aggressive sales approach utilized in animal health advertising that imply production problems are handled and cured through the use of a particular product. These realities are in conflict and create a serious clinical problem for the animal health specialist. Producers expect solutions to be quick and usually revolve around vaccination and treatment programs. Understanding nutrition and the impact it has on overall health is one way in which to remove this conflict and make better use of the biologicals and pharmaceuticals we have in our arsenal. By incoporating basic knowledge on cellular physiology, assay techniques for the protective oxidative (metallo) enzymes, and the use of computerized spreadsheet data analysis, my practice has developed an exciting and challenging approach to total herd health. It requires discipline, time, and continuing education. Resolving the conflict does not involve finding "new" cures, but rather a re-evaluation of cultural and scientific data already in existence with proper application to the intensified cattle production industry. Accept the challenge!

description: Inspired by the newly observed $P_{ψs}^Λ(4338)$ and the reported $P_{cs}(4459)$, we indicate the existence of the molecular-type characteristic mass spectrum for hidden-charm pentaquark with strangeness. It shows that the $P_{cs}(4459)$ may contain two substructures corresponding to the $Ξ_c\bar{D}^*$ molecular states with $J^P=1/2^-$ and $3/2^-$, while there exists the corresponding $Ξ_c \bar{D}$ molecular state with $J^P=1/2^-$. As the prediction, we present another characteristic mass spectrum of the $Ξ_c^\prime\bar{D}^{(*)}$ molecular states. Experimental confirmation of these characteristic mass spectra is a crucial step of constructing hadronic molecular family.

description: Developmental summer bridge programs are a popular strategy for increasing college readiness among recent high school graduates. Aimed at providing an alternative to traditional developmental education, these programs provide accelerated and focused learning opportunities in order to help students acquire the knowledge and skills needed for college success. The current study uses an experimental design to evaluate the outcomes of eight developmental summer bridge programs offered in Texas during the summer of 2009. At each college, students who consented to participate in the study were randomly assigned to either a program group that was eligible to participate in a developmental summer bridge program or a control group that was eligible to use any other services that the college provided. Based on a program model developed by the Texas Higher Education Coordinating Board, the developmental summer bridge programs in this study included four common features: accelerated instruction in developmental math, reading, and/or writing; academic support; a “college knowledge” component; and the opportunity to earn a $400 stipend.

lmmunomodulation in Bovine Respiratory Disease
Creators: name: Roth, James A.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1989

description: Animals are constantly exposed to the threat of bacterial, viral, and parasitic infection and neoplastic disease. The immune system is responsible for warding off these threats so that the animal remains healthy. The fact that the normal state of existence for animals is health attests to the remarkable efficiency of the immune system. When some factor(s) interferes with normal immune function or when an animal is exposed to an overwhelming number of an infectious agent, disease occurs. The basic understanding of the immune system is advancing rapidly and a picture of a highly regulated, complex system of cellular and molecular interactions is emerging. These breakthroughs in basic understanding promise to give scientists the means for manipulating the immune system to prevent disease from occurring rather than treating disease after it occurs. Advances in basic immunology have led to the identification of several compounds which show promise as immunomodulators. Immunomodulators are compounds that can "modulate" or enhance the function of the immune system and are sometimes called biological response modifiers. There are two basic types of immunomodulators: exogenous and endogenous. The exogenous immunomodulators include bacteria or bacterial derived products (e.g. Bacillus Calmette-Guerin (BCG), endotoxin, Propionobacterium acnes) and synthetic chemicals (e.g. levamisole and lipoidal amines). One mechanism of action of the exogenous immunomodulators is to induce the release of endogenous immunomodulators. The endogenous immunomodulators include proteins that are produced and secreted by cells (cytokines). Some examples of these proteins include interferons (IFN), interleukins (IL), tumor necrosis factors (TNF) and colony stimulating factors (CSF) (20). Genetic engineering techniques offer the potential to produce these compounds inexpensively. This manuscript focuses on research conducted at Iowa State University aimed at evaluating the potential for using immunomodulators in prevention and therapy of bovine respiratory disease. Research on immunomodulators in cattle has also been conducted by a number of other research groups, but will not be reviewed here.

Stress, Disease, and Vitamin E Requirements
Creators: name: Nockels, Cheryl F.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1989

description: Vitamin E supplementation of several animal species has increased their immunocompetence and mitigated their decreased production brought on by stress. The dietary level of vitamin E needed for increasing either disease or stress resistance appears to be greater than that required for growth and reproduction. These latter two responses are generally used as the criteria for determining the requirement of a nutrient. In stress and disease there is an increase in production of glucocorticoids, epinephrine, eicosanoids, and phagocytic activity. Eicosanoid and corticoid synthesis and phagocytic respiratory burst are prominent producers of free radicals which challenge the animal's antioxidant systems. Due to a number of factors, the antioxidant vitamin E status of an animal may be marginal or deficient prior to and/or after stress and disease. Since vitamin E status is integral to an animal's health and productivity, then it is imperative to be able to determine this status. Current research with cattle suggests that serum vitamin E levels may not be useful in defining its adequacy, but the red blood cell vitamin E content may be.

Dairy Herd Facilities Designed for Efficient Production
Creators: name: Armstrong, Dennis V.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1989

description: The major physical components of a dairy design are milking, feeding, treatment and waste-disposal facilities. These must be designed and located to provide animal comfort in combination with effective traffic and movement within the system for efficient day-to-day operation. The design of dairy components and complete systems depend upon certain management practices these will vary by climatic condition and herd size. Personal preference by individual dairymen may also influence the final selection of dairy design. Two major considerations in dairy design are cow comfort and reduce labor costs. Cow comfort usually means dairy design which modifies the environment for the cow to improve production (milk and production). This would include shade for cattle in a hot climate or a partial enclosed barn for protection from cold and wind in a cold climate. This paper will briefly deal with milking, feeding and waste-disposal of dairy design. A more detailed discussion of treatment facilities will be included.

description: Cosmological experiments often employ Bayesian workflows to derive constraints on cosmological and astrophysical parameters from their data. It has been shown that these constraints can be combined across different probes such as Planck and the Dark Energy Survey and that this can be a valuable exercise to improve our understanding of the universe and quantify tension between multiple experiments. However, these experiments are typically plagued by differing systematics, instrumental effects and contaminating signals, which we collectively refer to as `nuisance' components, that have to be modelled alongside target signals of interest. This leads to high dimensional parameter spaces, especially when combining data sets, with > 20 dimensions of which only around 5 correspond to key physical quantities. We present a means by which to combine constraints from different data sets in a computationally efficient manner by generating rapid, reusable and reliable marginal probability density estimators, giving us access to nuisance-free likelihoods. This is possible through the unique combination of nested sampling, which gives us access to Bayesian evidences, and the marginal Bayesian statistics code MARGARINE. Our method is lossless in the signal parameters, resulting in the same posterior distributions as would be found from a full nested sampling run over all nuisance parameters, and typically quicker than evaluating full likelihoods. We demonstrate our approach by applying it to the combination of posteriors from the Dark Energy Survey and Planck.

description: The relationship between a stockman and his cattle will affect productivity. Quiet, gentle handling will reduce stress on animals and improve production. Dairy cattle and other livestock readily adapt to many handling procedures. This paper will review how livestock adapt to handling procedures and ways to reduce handling stress. Reducing stress is important because stresses imposed during handling can have a detrimental effect on reproduction, milk production, immune function and rumen function. Restraint, electric prods and other handling stresses lowered conception rates.69,38,70 Transportation and restraint stress reduced the immune function in cattle and pigs.44,5,53 Rumen function was impaired by transit stress.19 In the studies conducted by Galyean,19 Kelley,44 and Blecha,5 the stress imposed by transit had a greater detrimental effect on the animal's physiology than the stress of feed and water derivation for the same length of time. Handling sheep with dogs and transport and sorting two to three weeks after mating caused early embryonic losses.11

Remodeling Existing Facilities

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1989

description: The buildings and equipment which comprise a dairy operation are there to facilitate the job of caring for the animals on the farm. Labor requirements, flow of animals and materials, pollution control, future expansion and management requirements are important considerations in design. Planning for new construction or remodeling of these dairy facilities must be based on a sound management plan. The plan sets forth all factors related to nutrition health and growth as well as all other activities of the dairy farm operation. The buildings and equipment which comprise dairy facilities are merely tools which allow essential tasks prescribed by the management plan to be carried out on a regular basis. Haphazard planning or impulsive acquisition of buildings or equipment will only lead to facilities which impede implementation of updated management plans and hinder future development and expansion. Providing environments that meet the needs of the animals being housed is important in design, also. While many of these needs may be obvious, the degree to which they are satisfied may vary widely. This may be due to a lack of understanding as to just what the needs of the animals are when it comes to establishing and maintaining their environment. For example, a warm barn for calves may have excessively high relative humidity due a lack of understanding of both the needs of the calves and the design and operation of the ventilation system. Or, it may result from an improper ordering of the priorities being used for design. For example, the establishment of the environment in a barn may place the needs of people and equipment ahead of the needs of the animals which are to be housed, oftentimes to the detriment of the animals. A discussion of some of the considerations for meeting the needs of dairy animals follows.

description: It is shown how extended supersymmetry realised directly on the (2,2) semichiral superfields of a symplectic sigma model gives rise to a geometry on the doubled tangent bundle consisting of two Yano F structures on an almost para-hermitian manifold. Closure of the algebra and invariance of the action is discussed in this framework and integrability of the F structures is defined and shown to hold. The reduction to the usual (1, 1) sigma model description and identification with the bi-quaternionic set of complex structures and their properties is elucidated. The F structure formulation should be applicable to many other models and will have an equivalent formulation in Generalised Geometry.

Year: 1989

description: Perhaps no area of the management program frustrates both dairyman and veterinarian alike more than reproduction. Both understand the critical importance of a sound reproduction program. As veterinarians we are trained primarily to diagnose, treat and hopefully prevent infectious disease problems. In today's modern dairy climate, where every effort is made to maximize productivity and profitability, we are increasingly faced with PRODUCTION disease problems. In this discussion, we will attempt to dramatically demonstrate the critical relationship that exists between energy status of the herd and reproductive performance. The discussion will address three areas: 1) Establish the energy-fertility relationship; 2) Identify DHIA record parameters that serve as indicators of the energy status, to both diagnose energy deficiency and predict the direction of future reproductive performance; and 3) Demonstrate the use of DHIA record analysis in correcting impaired fertility by establishing improved energy status of the herd. It is the graphic analysis of reproductive performance correlated to herd productivity that can clearly demonstrate to the dairy producer the importance of spending additional money to establish a more energy dense ration.

description: When an electron is scattered by a tightly-focused laser beam in vacuum, the intensity gradient is a critical factor to influence the electron dynamics, for example, the electron energy exchange with the laser fields as have been explored before [P.X.Wang et al.,J. Appl. Phys. 91, 856 (2002]. In this paper, we have further investigated its influence upon the electron high-harmonic generation (HHG) by treating the spacial gradient of the laser intensity as a ponderomotive potential. Based upon perturbative QED calculations, it has been found that the main effect of the intensity gradient is the broadening of the originally line HHG spectra. A one-to-one relationship can be built between the beam width and the corresponding line width. Hence this finding may provides us a promising way to measure the beam width of intense lasers in experiments. In addition, for a laser pulse, we have also studied the different influences from transverse and longitudinal intensity gradients upon HHG.
title: Modelling active particles in time-dependent fields
Creators: name: Ureña Marcos, José Carlos
Publisher: name: UNSPECIFIED
Year: 2023

description: Active particles tap into energy from their environment to produce persistent motion. Examples can be found on different lengthscales in nature, ranging from motile bacteria or sperm cells to birds or fish. They exploit their ability to self-propel to perform key tasks in their survival, which has inspired the assembly of synthetic active particles (also known as ‘microswimmers’ when they are micron sized), such as Janus colloids or droplet swimmers. The development of these motile (micro)agents holds great promise for tackling environmental and medical issues such as water treatment, targeted drug delivery or microsurgery. However, many challenges arise when conceiving these agents. For instance, control schemes need to be engineered so that these agents can navigate through complex environments, and their design has to be suitable for these environments. As of today, these challenges have not yet been optimally met. In this thesis, the control and design of autonomous motile agents are addressed, with the focus on how active particles behave in time-dependent fields. Firstly, a novel control scheme based on the use of ac fields is introduced. It exploits the interplay between (weak) rotational inertia and fast, unbiased ac fields to induce a persistent particle orientation. This control scheme is generically relevant for different types of active particles, such as artificial self-propelled colloids or vibrated granulates, in different setups, as illustrated here with Langevin dynamics simulations. A most remarkable example consists in inertial active particles self-propelling against a gravitational field and sedimenting at the top wall of the simulation box. An analytical framework based on a separation of fast and slow timescales is also presented, revealing that control can be gained by stabilising equilibrium points in the orientation dynamics of the particles thanks to the application of rapidly oscillating ac fields. Secondly, a new kind of self-powered, all-aqueous droplet swimmer is presented, which shows a dynamical transition from linear to chiral self-propulsion. This droplet swimmer emits surface tension–lowering polymer molecules, thus creating concentration and flow fields which change with time due to Marangoni flows and the droplet motion. In this work, the full time-dependent hydrodynamics of the droplet swimmer are modelled, with self-propulsion resulting from surface tension gradients along the water–droplet interface. Numerical simulations based on this model reveal that the transition to chiral motion is caused by the interaction of the droplet with its own chemical history through Marangoni flows. This new droplet swimmer has a higher level of autonomy, in terms of self-sustainability and dynamical diversity, than similar droplet swimmers realised in the past. Its features make it suitable for applications in environments where refuelling is not easily possible, such as biological media.

description: While more than 60% of associate degrees and 98% of higher education certificates are classified as “career education,” the value of these programs has been repeatedly questioned. In this paper, we review and develop the evidence base on occupational higher education in the community college sector. We begin by describing the extent and recent growth of occupational credentials, including diplomas and certificates, both in the community college system and the for-profit sector. We then review the evidence on the labor market returns to occupational programs, focusing particularly on whether patterns vary between metropolitan and non-metropolitan residents and by gender. Using SIPP data from 2008, we observe the returns across vocational certificates and associate degrees by field of study. Finally, we draw policy lessons and consider the implications of the Great Recession on changes in the labor market.
Dairy Production Medicine and Herd Monitoring

description: In a major shift toward preventive medical services in dairy practice, veterinarians are taking a more active role in the overall management and planning on dairies.1,2 Veterinarians are routinely offering services like nutritional consultation, housing design, and financial advice that were considered outside the realm of veterinary medicine in the past. The dairy practitioner is adapting to the role of herd health and productivity consultant. This evolution will expand the opportunity for veterinary services to dairy farmers, and will be a profitable interchange for practitioner and producer alike. As is always the case, there is a price to pay for this new opportunity. Veterinarians will need to develop the new practice skills to complete in this arena. These areas include nutrition, computers and record systems, finances, and effective marketing of these services. We must convince dairymen to look to veterinarians for new and different services. Veterinarians need to develop effective ways to deliver these services to their clients and to charge for their efforts.1,5

description: This paper presents a system for hardware-in-the-loop (HiL) simulation of unmanned aerial vehicle (UAV) control algorithms implemented on a heterogeneous SoC FPGA computing platforms. The AirSim simulator running on a PC and an Arty Z7 development board with a Zynq SoC chip from AMD Xilinx were used. Communication was carried out via a serial USB link. An application for autonomous landing on a specially marked landing strip was selected as a case study. A landing site detection algorithm was implemented on the Zynq SoC platform. This allowed processing a 1280 x 720 @ 60 fps video stream in real time. Performed tests showed that the system works correctly and there are no delays that could negatively affect the stability of the control. The proposed concept is characterised by relative simplicity and low implementation cost. At the same time, it can be applied to test various types of high-level perception and control algorithms for UAV implemented on embedded platforms. We provide the code developed on GitHub, which includes both Python scripts running on the PC and C code running on Arty Z7.

description: The static and the dynamic spin correlations in the low temperature collapsed tetragonal and the high temperature tetragonal phase in CaFe2As2 have been investigated by 75As nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) measurements. Through the temperature (T) dependence of the nuclear spin lattice relaxation rates (1/T1) and the Knight shifts, although stripe-type antiferromagnetic (AFM) spin correlations are realized in the high temperature tetragonal phase, no trace of the AFM spin correlations can be found in the non-superconducting, low temperature, collapsed tetragonal (cT) phase. Given that there is no magnetic broadening in 75As NMR spectra, together with the T-independent behavior of magnetic susceptibility (x) and the T dependence of 1/T1Tx, we conclude that Fe spin correlations are completely quenched statically and dynamically in the non-superconducting cT phase in CaFe2As2.

description: We study phenomenological aspects of the bino-wino co-annihilation scenario in high-scale supersymmetry breaking models. High-scale SUSY breaking scenarios are considered to be promising possibility after the discovery of the Higgs boson with a mass around 126 GeV. In this paper, we discuss the bino lightest supersymmetric particle (LSP) accompanied by the at most around 30 GeV heavier wino. With the suitable mass splitting between the bino and the wino, the bino LSP has the correct relic abundance of dark matter. For the smaller mass splitting, the late-time decay of the gravitino can provide the correct abundance of the bino dark matter. It is extremely challenging to find signals from the bino dark matter in direct and indirect detections. By utilizing multi-jets plus missing transverse momentum events at the LHC, we can constraint the gluino mass and thus probe the bino-wino co-annihilation scenario indirectly. The collider experiment, however, can not search the bino dark matter directly. In this paper, we suggest the direct probe of the bino dark matter. We show that the bino dark matter leaves imprints on the small-scale matter power spectrum when the bino dark matter is produced by the decay of the gravitino. The non-thermal bino dark matter behaves as mixed (cold+warm) dark matter.

description: In recent years, event cameras (DVS - Dynamic Vision Sensors) have been used in vision systems as an alternative or supplement to traditional cameras. They are characterised by high dynamic range, high temporal resolution, low latency, and reliable performance in limited lighting conditions -- parameters that are particularly important in the context of advanced driver assistance systems (ADAS) and self-driving cars. In this work, we test whether these rather novel sensors can be applied to the popular task of traffic sign detection. To this end, we analyse different representations of the event data: event frame, event frequency, and the exponentially decaying time surface, and apply video frame reconstruction using a deep neural network called FireNet. We use the deep convolutional neural network YOLOv4 as a detector. For particular representations, we obtain a detection accuracy in the range of 86.9-88.9% mAP@0.5. The use of a fusion of the considered representations allows us to obtain a detector with higher accuracy of 89.9% mAP@0.5. In comparison, the detector for the frames reconstructed with FireNet is characterised by an accuracy of 72.67% mAP@0.5. The results obtained illustrate the potential of event cameras in automotive applications, either as standalone sensors or in close cooperation with typical frame-based cameras.

description: Community colleges enroll large numbers of nontraditional students who are at greater risk for non-persistence in college. This research examines the influence of validation by faculty on students’ sense of integration in college and intent to persist. Three student characteristics were taken into account: gender, race/ethnicity, and age. For each sub-group, an assessment was made of the extent to which higher rates of faculty validation predicted a greater sense of integration or intent to persist. Higher rates of faculty validation moderately to strongly predicted students’ sense of integration. With regard to the extent to which faculty validation predicts students’ intent to persist at the college, significant, positive results were found for females, Hispanic students, and both younger and older students.

description: Simulating mobile liquid-gas interfaces with the free-surface lattice Boltzmann method (FSLBM) requires frequent re-initialization of fluid flow information in computational cells that convert from gas to liquid. The corresponding algorithm, here referred to as the refilling scheme, is crucial for the successful application of the FSLBM in terms of accuracy and numerical stability. This study compares five refilling schemes that extract information from the surrounding liquid and interface cells by averaging, extrapolating, or assuming one of the three different equilibrium states. Six numerical experiments were performed, covering a broad spectrum of possible scenarios. These include a standing gravity wave, a rectangular and cylindrical dam break, a Taylor bubble, a drop impact into liquid, and a bubbly plane Poiseuille flow. In some simulations, the averaging, extrapolation, and one equilibrium-based scheme were numerically unstable. Overall, the results have shown that the simplest equilibrium-based scheme should be preferred in terms of numerical stability, computational cost, accuracy, and ease of implementation.

Health Programs for Productivity Using Bovine Somatotropin (BST)
Creators: name: Weaver, L. D.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1989

description: Production medicine programs for Bovine Somatotropin (BST)-treated herds will be similar to programs in high producing herds. Veterinary activities will include reproductive health, nutrition, udder health and production monitoring services. Available research data indicate little effect on cow health or fertility in animals receiving BST at efficacious levels. Primary concerns are maintaining/restoring body condition, reproduction management options and consumer/marketing issues. This presentation will briefly discuss disease effects other than those associated with nutrition, reproduction and udder health, outline possible treatment strategies, describe dry cow and fresh cow management for BST treated herds and present a rationale for on-line production monitoring.

Udder Health and BST
Creators: name: Sears, Philip M.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1989

description: "Higher production will hurt the small producer, increase stress and enhance disease". These cliches are not new and have accompanied most major changes in the dairy industry dealing with milk production. They are not all untruths, and many management changes have affected exposure and risk to both metabolic and infectious diseases which challenge our traditional approach to disease control. Understanding the new sciences and using them properly are challenges we must face in our herd health programs. Historically, the elimination of Streptococcus agalactiae in a herd has not assured the control of mastitis unless combined with measures to reduce other sources of infections in the herd. Lowering the somatic cell count in a herd results in increased production, but without proper environmental controls, increased clinical mastitis can offset the benefits of reduced subclinical mastitis. Most of our management changes have resulted in improved production, better milk quality or positive cost-benefits ration for the producer. Bovine somatotropin (BST) is the most recent scientific advancement in the industry, offering benefits but sharing concerns as seen in the past. Unlike other new advances, few improvements have received as much publicity or as much scientific research evaluation.

The nonlinear stability of rotationally symmetric spaces with low regularity

description: We consider rotationally symmetric spaces with low regularity, which we regard as integral currents spaces or manifolds with Sobolev regularity and are assumed to have nonnegative scalar curvature. Relying on the flat distance and on Sobolev norms, we establish several nonlinear stability estimates about the ``distance'' between a rotationally symmetric manifold and the Euclidian space, which are stated in terms of the ADM mass of the manifold. Importantly, we make explicit the dependencies and scales involved in this problem, particularly the ADM mass, the depth, and the CMC reference hypersurface. Several notions of independent interest are introduced in the course of our analysis, including the notion of depth of a manifold and a scaled version of the flat-distance, the D-flat distance as we call it, which involves the diameter of the manifold. Finally we prove a compactness theorem for sequences of regions with uniformly bounded depth, whose outer boundaries have fixed area and an upper bound on Hawking mass.

Nutritional Aspects of Bovine Somatotropin (BST)

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1989

description: As milk production increases 2 to 3 percent annually, nutrient demands for high producing cows will continue to be a major management challenge. Minnesota DHI data illustrate the shift in feeding programs and strategies as milk yield increases (Table 1). Bovine somatotropin (BST) is biotechnology that could increase milk yield 5 to 15 percent in the future. Mix (1987) predicted in the year 2000, average milk yield could be 16,335 pounds without BST or 20,418 pounds if BST was used by U.S. dairy farmers. Meeting the nutritional needs of BST treated cows must be understood by dairy farmers, dairy nutritionists, veterinarians, and agri-business personnel. By examining current feeding strategies in high producing herds, three-times-a day milking, and BST research, BST feeding strategies can be anticipated.
