description: Radiative transfer modeling of spectral lines including partial redistribution (PRD) effects requires the evaluation of the ratio of the emission to the absorption profile. This quantity requires a large amount of computational work if one employs the angle-dependent redistribution function, which prohibits its use in 3D radiative transfer computations with model atmospheres containing velocity fields. We aim to provide a method to compute the emission to absorption profile ratio that requires less computational work but retains the effect of angle-dependent scattering in the resulting line profiles. We present a method to compute the profile ratio that employs the angle-averaged redistribution function and wavelength transforms to and from the rest frame of the scattering particles. We compare the emergent line profiles of the \MgII\,k and \Lyalpha\ lines computed with angle-dependent PRD, angle-averaged PRD and our new method in two representative test atmospheres. The new method yields a good approximation of true angle-dependent profile ratio and the resulting emergent line profiles while keeping the computational speed and simplicity of angle-averaged PRD theory.

description: INGs or Inhibitor of Growth proteins act as type II tumor suppressors in epithelial cancers. The senescence associated secretory phenotype (SASP) is a phenomenon where senescent cells secrete a defined group of proteins including various proinflammatory cytokines. Cancer-associated fibroblasts (CAFs) are another component of the tumor microenvironment secreting various growth factors, proinflammatory cytokines and proteases. The proinflammatory cytokines secreted by CAFs and senescent cells as SASP cause chronic inflammation, which is one of the hallmarks of cancer. Although generally described as a tumor suppressor, our lab has recently reported that higher ING1 levels in the stroma correlate with poor survival outcome in breast cancer patients. To better understand this, we examined the effects of altering ING1b levels in fibroblasts. We find that ING1b increases the secretion of IL8, IL6, CXCL1 and CCL7 (also secreted by CAFs and in the SASP). This most likely occurs by ING1b activating NF-κB. Factors secreted by fibroblasts in response to ING1b also enhances the growth and migration capacity of several lines of breast cancer cells and also induce a cancer like phenotype of migration and growth in normal breast epithelial cells.

description: Objective: The aim of the study was to prepare and evaluate buccal-adhesive tablets of Buspirone HCl that avoid gastric degradation and first pass metabolism, thereby increasing the drug bioavailability and onset of action. Buspirone HCl belongs to a class anxiolytic agent and a serotonin receptor agonist belonging to the azaspirodecanedione class of compounds. Methods: In the present work, different ratios of Gantrez MS 955 along with Carbopol 934 were studied to give bioadhesive strength. A 32 full factorial design was applied to investigate the combined effect of concentration Carbopol 934 (X1) i.e. 5,7.5,10 mg and Gantrez MS 955 concentration (X2) i.e. 10,12.5,15 mg. Results: Results of the multiple regression analysis revealed that the independent variables significantly affected the dependent variables (bioadhesive strength (Y1), Q2 (Y2), Q3 (Y3), Q4 (Y4)). On the basis of multiple linear regression analysis and contour plot evaluation, it was found that combination of two polymers possessed excellent mucoadhesive properties allowing ease of application and removal of the tablets from the buccal mucosa. Conclusion: The formulation batch A9 fulfilled all the criteria set from the desirability search. From the in vitro diffusion study flux was calculated for the optimized batch. Study of the effect of tablet diameter and the environmental factors on the bioadhesion of the tablet was done. To study the environmental factor on bioadhesion, prehydration time and contact time were considered. Result found that increase in prehydration time decrease in bioadhesive strength and increase in contact time increased bioadhesive strength. Thus a stable Buccoadhesive formulation optimized for formulation ingredients and process parameters was prepared successfully.

description: Macroscopic and robust supercurrents are observed by direct electron transport measurements on a silicon surface reconstruction with In adatoms (Si(111)-(R7xR3)-In). The superconducting transition manifests itself as an emergence of the zero resistance state below 2.8 K. $I-V$ characteristics exhibit sharp and hysteretic switching between superconducting and normal states with well-defined critical and retrapping currents. The two-dimensional (2D) critical current density $J_\mathrm{2D,c}$ is estimated to be as high as $1.8 \ \mathrm{A/m}$ at 1.8 K. The temperature dependence of $J_\mathrm{2D,c}$ indicates that the surface atomic steps play the role of strongly coupled Josephson junctions.
description: 4 pages, 3 figures; The error in the values of 2D critical current density $J_\mathrm{2D,c}$ was corrected. In the old version, the numbers were wrong by a factor of 100 due to a mechanical error. This does not affect the following analysis and conclusion

description: Money is crucial to the functioning of democracy and is often used as a tool to influence the political process. However, concerns about real or perceived corruption has led many jurisdictions to regulate political finances. Politics in the Maritime Provinces have long been notorious for corrupt practices. Yet, political finance regimes have existed in these provinces for several decades. Using historical and political contexts and three benchmarks for political finance regulation—equality of opportunity for political actors, equality of opportunity for private actors, and mitigation of corruption—the effectiveness of the regimes in the Maritime provinces is assessed. Differing experiences with internal and external pressures for reform have led to varying results. In Nova Scotia and New Brunswick, internal pressures due to shifting attitudes toward equality led to more comprehensive and effective regimes than that of PEI, which was spurred by external forces through a contagion effect.
Three Essays in Luck, Effort, and Economic Opportunity

Subjects: subject: Economics
subject: Effort
subject: Distributional Justice
subject: Luck
subject: Opportunities

description: This thesis consists of an introduction and three essays studying the role of opportunities, effort and luck in economic decision making. The introduction argues that effort and redistribution choices rely on understanding the relative roles of these factors. Yet, individuals do not know the actual relative roles and act based on beliefs. Chapter 2 studies the effect of children on the likelihood of self-employment. On the one hand, individuals’ preference for autonomy and flexibility increases when having children, which increases the willingness to be self-employed. On the other hand, having children entails a responsibility over someone else, which increases individual risk aversion and decreases the willingness to be self-employed. Using a pooled cross section of 26 years from the General Social Survey, instrumental variable estimates indicate that, in the USA, having children under the age of 18 in the household decreases the likelihood of being self-employed by 11%. Chapter 3 theoretically examines whether social segregation can explain differences in beliefs regarding the role of effort in determining high incomes. I develop a model of lineages of agents learning about the effect of effort on the probability of receiving a high income based on their own experience and the experiences of agents in their networks. I find a positive relationship between the degree of social segregation and the level of long-run differences in beliefs, including cases of polarization. Moreover, high levels of social segregation can lead agents to make inefficient effort choices while average beliefs drift away from real parameters. Chapter 4 presents a lab experiment examining the effect of information regarding effort and opportunities in ex-post redistribution behavior. Participants are randomly endowed one of two probabilities of winning $20 (opportunities). By exerting effort individuals can increase their probability of winning $20, but conditional on effort the difference in probabilities remain constant. Redistribution takes place between a dictator who won $20 and a recipient who won $0. Treatments vary (i) the inequality of opportunities and (ii) information regarding recipients’ effort and opportunities. I find dictators consistently give less to low-effort recipients. However, dictators do not significantly consider opportunities when redistributing.

description: Computed tomography (CT) to cone-beam computed tomography (CBCT) deformable image registration (DIR) is a crucial step in adaptive radiation therapy. Current intensity-based registration algorithms, such as demons, may fail in the context of CT-CBCT DIR because of inconsistent intensities between the two modalities. In this paper, we propose a variant of demons, called Deformation with Intensity Simultaneously Corrected (DISC), to deal with CT-CBCT DIR. DISC distinguishes itself from the original demons algorithm by performing an adaptive intensity correction step on the CBCT image at every iteration step of the demons registration. Specifically, the intensity correction of a voxel in CBCT is achieved by matching the first and the second moments of the voxel intensities inside a patch around the voxel with those on the CT image. It is expected that such a strategy can remove artifacts in the CBCT image, as well as ensuring the intensity consistency between the two modalities. DISC is implemented on computer graphics processing units (GPUs) in compute unified device architecture (CUDA) programming environment. The performance of DISC is evaluated on a simulated patient case and six clinical head-and-neck cancer patient data. It is found that DISC is robust against the CBCT artifacts and intensity inconsistency and significantly improves the registration accuracy when compared with the original demons.

The mystery of the whelk egg capsule protein : electrospinning, mechanical testing, and being outsmarted by an invertebrate
Creators: name: Corbett, Carla M.
Publisher: name: University of British Columbia
Year: 2010

description: Whelks are carnivorous marine snails known for their elaborate and durable egg capsules. The mechanically complex capsules have been previously studied, and shown to have mechanical behaviour similar to keratin. The mature protein has an initial stiff linear elastic region at low strain, followed by a rubbery yield region with a fully repeatable order of magnitude decrease in stiffness. The material properties of the protein mature in distinct stages, with long-range elasticity developing first, followed by the development of the stiff Hookean region. As the capsule matures, it is massaged by a gland in the foot of the snail, which probably enables cross-linking. This study sought to mimic the development process using electrospinning to create fibres with charge-based assembly, then adding a cross-linking step to encourage the stiff spring behaviour to form. An electrospinning protocol was developed and parameters were optimized. The technique was applied successfully, and the resulting protein nanofibres could be cross-linked. The electrospun protein fibres were shown to have composition and secondary structures similar to the native protein. However, the mechanical properties of the cross-linked nanofibres were more similar to a transitional stage in the egg capsule’s maturation sequence than they were to the mature capsule. The fibres did not exhibit the bimodal behaviour seen in the native polymer.

description: We investigate the dynamics of $U(1)$ gauged Q-balls using fully three-dimensional numerical simulations. We consider two different scenarios: first, the classical stability of gauged Q-balls with respect to generic three-dimensional perturbations, and second, the behaviour of gauged Q-balls during head-on and off-axis collisions at relativistic velocities. With regard to stability, we find that there exist gauged Q-ball configurations which are classically stable in both logarithmic and polynomial scalar field models. With regard to relativistic collisions, we find that the dynamics can depend on many different parameters such as the collision velocity, relative phase, relative charge, and impact parameter of the colliding Q-balls.

description: The area of geometry with its very strong and appealing visual contents and its also strong and appealing connection between the visual content and its formal specification, is an area where computational tools can enhance, in a significant way, the learning environments. The dynamic geometry software systems (DGSs) can be used to explore the visual contents of geometry. This already mature tools allows an easy construction of geometric figures build from free objects and elementary constructions. The geometric automated theorem provers (GATPs) allows formal deductive reasoning about geometric constructions, extending the reasoning via concrete instances in a given model to formal deductive reasoning in a geometric theory. An adaptative and collaborative blended-learning environment where the DGS and GATP features could be fully explored would be, in our opinion a very rich and challenging learning environment for teachers and students. In this text we will describe the Web Geometry Laboratory a Web environment incorporating a DGS and a repository of geometric problems, that can be used in a synchronous and asynchronous fashion and with some adaptative and collaborative features. As future work we want to enhance the adaptative and collaborative aspects of the environment and also to incorporate a GATP, constructing a dynamic and individualised learning environment for geometry.

description: Shrimp farming has the potential to create jobs and improve the livelihoods of Sri Lanka’s rural poor. With past disease outbreaks having caused production losses, farm abandonment, and unemployment among smallholder shrimp farmers, growth in this industry must be ecologically, socially, and economically sustainable. We evaluated sustainability statuses of farms in two Sri Lankan provinces and assessed management practices associated with lower disease prevalence. Farms in the more established North Western Province, despite having disease problems, had higher sustainability scores than farms in the Eastern Province. Variables such as disease outbreaks and poor water quality may therefore drive increased implementation of sustainable practices. Additionally, farms that followed more best management practices were less likely to report disease. Implementation of best management practices should be encouraged, particularly practices associated with lower disease prevalence. This thesis may help target education and policy programs to improve sustainability of smallholder Sri Lankan shrimp farms.

description: The zCOSMOS SINFONI project is aimed at studying the physical and kinematical properties of a sample of massive z~1.4-2.5 star-forming galaxies, through SINFONI near-IR integral field spectroscopy (IFS), combined with the multi-wavelength information from the zCOSMOS (COSMOS) survey. The project is based on 1 hour of natural-seeing observations per target, and Adaptive Optics (AO) follow-up for a major part of the sample, which includes 30 galaxies selected from the zCOSMOS/VIMOS spectroscopic survey. This first paper presents the sample selection, and the global physical characterization of the target galaxies from multicolor photometry, i.e., star formation rate (SFR), stellar mass, age, etc. The Halpha integrated properties such as, flux, velocity dispersion, and size, are derived from the natural-seeing observations, while the follow up AO observations will be presented in the next paper of this series. Our sample appears to be well representative of star-forming galaxies at z~2, covering a wide range in mass and SFR. The Halpha integrated properties of the 25 Halpha detected galaxies are similar to those of other IFS samples at the same redshifts. Good agreement is found among the SFRs derived from Halpha luminosity and other diagnostic methods, provided the extinction affecting the Halpha luminosity is about twice that affecting the continuum. A preliminary kinematic analysis, based on the maximum observed velocity difference across the source, and on the integrated velocity dispersion, indicates that the sample splits nearly 50-50 into rotation-dominated and velocity dispersion-dominated galaxies, in good agreement with previous surveys.

description: The scattering polarization in the solar spectrum is traditionally modeled with each spectral line treated separately, but this is generally inadequate for multiplets where J-state interference plays a significant role. Through simultaneous observations of all the 3 lines of a Cr I triplet, combined with realistic radiative transfer modeling of the data, we show that it is necessary to include J-state interference consistently when modeling lines with partially interacting fine structure components. Polarized line formation theory that includes J-state interference effects together with partial frequency redistribution for a two-term atom is used to model the observations. Collisional frequency redistribution is also accounted for. We show that the resonance polarization in the Cr I triplet is strongly affected by the partial frequency redistribution effects in the line core and near wing peaks. The Cr I triplet is quite sensitive to the temperature structure of the photospheric layers. Our complete frequency redistribution calculations in semi-empirical models of the solar atmosphere cannot reproduce the observed near wing polarization or the cross-over of the Stokes Q/I line polarization about the continuum polarization level that is due to the J-state interference. When however partial frequency redistribution is included, a good fit to these features can be achieved. Further, to obtain a good fit to the far wings, a small temperature enhancement of the FALF model in the photospheric layers is necessary.

description: We have performed a careful investigation of the 74 candidate variable stars presented by Safanova & Stalin (2011). For this purpose we used our data base of imaging and light curves from Arellano Ferro et al. (2011) and Arellano Ferro et al. (2012). We find that two candidates are known variable stars, eight candidates were discovered first by Arellano Ferro et al. (2011) but would not have been known to Safanova & Stalin (2011) at the time of their paper submission, while four candidates are new variables. Three of the new variables are SX Phe type and one is a semi-regular red giant variable (SR type). We also tentatively confirm the presence of true variability in two other candidates and we are unable to investigate another four candidates because they are not in our data base. However, we find that the remaining 54 candidate variable stars are spurious detections where systematic trends in the light curves have been mistaken for true variability. We believe that the erroneous detections are caused by the adoption of a very low detection threshold used to identify these candidates.

description: Breast cancer poses a significant global health challenge, with 2.3 million new cases diagnosed in 2020. Early detection and personalized care are crucial for improving outcomes and quality of life. Artificial Intelligence (AI) has emerged as a transformative tool in breast cancer care, offering diagnostic, predictive, and treatment optimization capabilities. While AI applications have been explored extensively in diagnostic imaging and treatment planning, their potential in enhancing patient management, understanding, and education remains a critical area. A scoping review is proposed to comprehensively assess existing literature on AI's role in breast cancer patient care and education, filling a gap in current research. The review aims to explore the types of AI models employed across various stages of patient care, including diagnosis, surgical interventions, medical management, and post-treatment follow-up. The overarching goal is to facilitate a more effective integration of AI into breast cancer management, ultimately improving global healthcare outcomes and advancing medical practices. The review question seeks to uncover insights from existing literature regarding the use of AI in delivering care and education to breast cancer patients.

description: The Ly-alpha line of He II at 304 Å is one of the spectral lines of choice for EUV channels of narrow-band imagers on board space telescopes, which provide spectacular intensity images of the outer solar atmosphere. Since the magnetic field information is encoded in the polarization of the spectral line radiation, it is important to investigate whether the He II line radiation from the solar disk can be polarized, along with its magnetic sensitivity. Here we report some theoretical predictions concerning the linear polarization signals produced by scattering processes in this strong emission line of the solar transition region, taking into account radiative transfer and the Hanle effect caused by the presence of organized and random magnetic fields. We find that the fractional polarization amplitudes are significant (${\sim}1%$), even when considering the wavelength-integrated signals. Interestingly, the scattering polarization of the Ly-alpha line of He II starts to be sensitive to the Hanle effect for magnetic strengths B>100 G (i.e., for magnetic strengths of the order of and larger than the Hanle saturation field of the hydrogen Ly-alpha line at 1216 Å). We therefore propose simultaneous observations of the scattering polarization in both Ly-alpha lines to facilitate magnetic field measurements in the upper solar chromosphere. Even the development of a narrow-band imaging polarimeter for the He II 304 Å line alone would be already of great diagnostic value for probing the solar transition region.

By considering the symmetries of the theory, we show that the foreground and background null energy conditions (NECs) are strongly anti-correlated. In particular, the NECs can only be simultaneously fulfilled when they saturate, corresponding to foreground and background cosmological constants. In all other situations, either the foreground or the background is subject to a NEC-violating contribution to the total stress-energy.

description: In this paper, we generalize Walcher's computation of the open Gromov-Witten invariants of the quintic hypersurface to Fano and Calabi-Yau projective hypersurfaces. Our main tool is the open virtual structure constants. We also propose the generalized mirror transformation for the open Gromov-Witten invariants, some parts of which are proven explicitly. We also discuss possible modification of the multiple covering formula for the case of higher dimensional Calabi-Yau manifolds. The generalized disk invariants for some Calabi-Yau and Fano manifolds are shown and they are certainly integers after re-summation by the modified multiple covering formula. This paper also contains the direct integration method of the period integrals for higher dimensional Calabi-Yau hypersurfaces in the appendix.

description: This paper proposes a novel inventory management model for the replenishment strategy of a satellite mega-constellation incorporating dual supply modes: normal and auxiliary. The proposed framework employs an indirect channel for normal supply, wherein spare satellites are initially injected into a parking orbit before transferring to the target orbital plane via propulsion systems and orbital perturbations. Conversely, the auxiliary supply mode utilizes a direct channel, injecting spare satellites immediately into their designated orbital planes. The inventory management model is constructed using parametric replenishment policies: $\left(s,Q\right)$ and $\left(R_1,R_2,Q_1,Q_2\right)$ with a time window. Following this model, two optimization problems are addressed to construct the supply chain for satellite mega-constellation replenishment and to evaluate its performance. These are decision-making contexts from the perspectives of constellation operators and launch service providers. The case study showcases the practical applicability of the proposed model and optimization problems, yielding valuable insights for stakeholders in the spaceborne industry.

Airway smooth muscle in health and disease
Creators: name: Chin, Leslie Yee Mann
Publisher: name: University of British Columbia

description: This thesis focuses on the structure and function of airway smooth muscle (ASM) in health and disease. By employing the use of structural analysis by electron microscopy, functional analysis by mechanical measurements, and biochemical analysis, this thesis provides valuable insight into ASM pathophysiology. The first two chapters focus on the mechanisms by which the contractile apparatus is arranged within the cell. The studies examined whether the actin filament lattice acts a scaffold to facilitate myosin filament assembly within contractile units and the contractile response to potassium chloride (KCl). The muscle was treated with cytochalasin D (CD), a known actin filament disrupter, but this provided little insight on whether the actin lattice guides myosin filament assembly, since CD had a limited effect on actin filaments but a significant effect on force. KCl was found to cause contraction of similar force to acetylcholine contraction, despite the presence of fewer myosin filaments. KCl likely caused depolymerization of myosin filaments upon activation and allowed for force generation by non-filamentous myosin molecules. In the last two studies, human ASM was sourced from the tracheas of whole lungs donated for medical research. From this tissue source it was shown that, unlike in previous human ASM studies, human muscle is similar to that of other mammalian species and capable of significant isotonic shortening. This finding lends support to the use of animal ASM models as a proxy for human ASM. This also was the first study to examine human ASM in the paradigm of mechanical plasticity, using in situ muscle length as a reference length instead of the traditional Lmax, and was the first to demonstrate length adaptation in human ASM. The mechanical properties of asthmatic ASM were found to differ from those of non-asthmatic ASM at several key measurements. Asthmatic ASM was found to have an altered length-tension relationship, increased passive tension, and maintained force better in response to a mechanical perturbation than non-asthmatic ASM. This last finding provides a possible mechanism by which asthmatic airways are more resistant to the bronchodilating effects of deep inspiration. Force generating capacity, shortening extent and velocity were not different.

description: As autonomous vehicle technology advances, the precise assessment of safety in complex traffic scenarios becomes crucial, especially in mixed-vehicle environments where human perception of safety must be taken into account. This paper presents a framework designed for assessing traffic safety in multi-vehicle situations, facilitating the simultaneous utilization of diverse objective safety metrics. Additionally, it allows the integration of subjective perception of safety by adjusting model parameters. The framework was applied to evaluate various model configurations in car-following scenarios on a highway, utilizing naturalistic driving datasets. The evaluation of the model showed an outstanding performance, particularly when integrating multiple objective safety measures. Furthermore, the performance was significantly enhanced when considering all surrounding vehicles.

description: We present an approach to program reasoning which inserts between a program and its verification conditions an additional layer, the denotation of the program expressed in a declarative form. The program is first translated into its denotation from which subsequently the verification conditions are generated. However, even before (and independently of) any verification attempt, one may investigate the denotation itself to get insight into the "semantic essence" of the program, in particular to see whether the denotation indeed gives reason to believe that the program has the expected behavior. Errors in the program and in the meta-information may thus be detected and fixed prior to actually performing the formal verification. More concretely, following the relational approach to program semantics, we model the effect of a program as a binary relation on program states. A formal calculus is devised to derive from a program a logic formula that describes this relation and is subject for inspection and manipulation. We have implemented this idea in a comprehensive form in the RISC ProgramExplorer, a new program reasoning environment for educational purposes which encompasses the previously developed RISC ProofNavigator as an interactive proving assistant.

description: Normanion hipposideros sp. nov. (Figs 1, 2) Type material. HOLOTYPE, female, 2.5 mm, AM P.69040, Horseshoe Reef, Horsehoe Reef, Bootless Inlet, Papua New Guinea, 9°30.5’S 147°15.5’E, 12–15 m, coral rubble from reef front slope, 29 October 1980, J.K. Lowry, stn PNG-32. Type locality. Horsehoe Reef, Bootless Inlet, Papua New Guinea, 9°30.5’S 147°15.5’E, 12–15 m depth. Etymology. The species name is the Greek word for a horseshoe, a reference to the type locality. Diagnostic description. Antenna 1 callynophore present. Eyes present. Mouthpart bundle subconical. Mandible left and right incisor with slightly convex margin, smooth; lacinia mobilis absent; molar present, setose; palp attached proximally, articles 2 and 3 subequal. Maxilla 1 outer plate with 10 setal teeth in an 8/2 crown arrangement, some of outer row with cusps in 2 rows; palp apical margin serrate, with apical robust setae. Maxilliped palp 4-articulate, article 4 vestigial. Gnathopod 1 subchelate; ischium long; carpus posterior margin not produced, curved; propodus subquadrate, proximal margin produced into strong posteroproximal lobe, palm serrate, posterodistal corner not produced, with 3 robust setae. Gnathopod 2 minutely chelate; carpus longer than propodus (about 1.5x); palm obtuse. Pereopod 4 coxa posteroproximal excavation large. Pereopods 5–7 basis with smooth posterior margin; [dactylus not known]. Epimeron 3 posterior margin smooth, posteroventral corner broadly rounded. [Uropod 3 unknown.] Telson about as long as broad, entire, distally emarginate, without dorsal robust setae. Male not known. Remarks. Unfortunately the specimen lacks the distal articles of pereopods 5–7 and uropod 3. Normanion hipposideros has the unusual character of having two rows of cusps on some of the outer row of setal teeth on the maxilla 1 outer plate, a character which also occurs in Podoprionella dagadugaban Lowry & Stoddart, 1995. Although the status of uropod 3 is not known for N. hipposideros the presence of a large setose molar excludes the species from the genus Podoprionella. See also remarks under N. whoi. Distribution. Southern Papua New Guinea; 12–15 m depth.

Dynamic Characterization of Naturally Fractured Reservoirs with Fractal Geometry: Methodology of Analysis

Subjects: subject: Engineering--Petroleum
subject: Fractal

description: Naturally Fractured Reservoirs (NFR) contain over 60% of hydrocarbon reserves in the world. Most NFR have heterogeneities occurring in a wide range of spatial scales. Generally, NFR are modeled using Euclidean geometry with homogeneous fracture systems that work well for some specific cases. However, the presence of fractures at different scales, the non-uniform distribution of fractures, and the connectivity of the fracture network are important factors of uncertainty in reservoir models. Fractal geometry is one of the best ways to take into account heterogeneities present in a porous medium at different scales, their non-uniform distribution in space, and the connectivity of the fracture network. This thesis puts forward a methodology to identify, validate and define the fractal parameters from NFR. It considers reservoir engineering and geologic information to gain a comprehensive understanding of this type of reservoirs. This methodology was applied to two field cases from the southwest of Mexico.

description: A cow comfort assessment was conducted on 60 Holstein-Friesian cows per farm on three categories of farms: 15 that changed the freestall area (CHANGE) after a previous assessment; 15 that did not change the freestall area (NOCHANGE) after a previous assessment; and 14 that were never evaluated (NEW). The CHANGE group had decreased lameness prevalence and increased lying time compared to the NOCHANGE group, the NEW group, and data from previous cow comfort assessments. Additionally, farmers in CHANGE and NOCHANGE groups more frequently identified the importance of risk factors associated with cow comfort than in their previous assessment. In conclusion, the CHANGE group improved in outcome measures of cow comfort, and farms in both CHANGE and NOCHANGE groups became more aware of risk factors regarding cow comfort than during a previous assessment.
