O programa é suficientemente flexível de modo que novas interfaces gráficas de outros métodos elétricos e eletromagnéticos podem ser facilmente implementadas.
We present a graphic interface for the program eGs (electrical GEOPHYSICS suite) used for modeling and interpretation of electric and electromagnetic data in geophysical exploration. This master degree dissertation corresponds the portion of the program that treats the interfaces for bi and three-dimensional input data of geoelectrical models together with interfaces for the presentation of the modeling results and for the presentation of observed data as well. The program contains interfaces for creation, modification and visualization of bi and threedimensional geoelectrical models and for illustrations of the calculated results through graphs and images. This work gives a program with several options to alter the geometry and the physical properties of the geoelectrical models, including facilities for three dimensions visualization in order to help geophysical data interpretation. The graphic interfaces can be used to create geoelectrical models associated with the most used electric and electromagnetic geophysical methods and to analyze the answers obtained by numerical modeling associated with different types of observed data in field campaign. The program is sufficiently flexible so that new graphic interfaces of other electric and electromagnetic methods can be implemented easily.

An Enhanced Geothermal System (EGS) allows for the generation of electricity using the Earth's heat by improving ('enhancing') the fracture permeability of rock and flowing fluid through the optimized medium. The complex behavior of EGS fracture systems and heat flow processes are being studied at various scales to determine the practical capabilities of EGS technology. The EGS collaborative (Collab) project is focused on experimentation of intermediate-scale (i.e., 10's of meters) EGS reservoir generation processes and model validation at crystalline rock sites. A key phase of the project involves seismic characterization of a rock mass intended to be representative of EGS reservoir rock. A suite of boreholes was drilled from inside a mine drift on the 4850-foot (~1.5 km) level of the Sanford Underground Research Facility (SURF) in Lead, South Dakota. The boreholes, comprised of one stimulation (injection) well, one production (extraction) well, and six monitoring wells, were each nominally drilled approximately 200 feet (~60 meters) deep into the surrounding crystalline rock formation near the location of a previous experiment at this site (kISMET). Active source seismic data were collected using an electrical sparker source and an electro-mechanical impulse source to generate compressional (P-) wave and shear (S-) wave energy, respectively, at varying depths in the stimulation well. Seismic receivers were deployed in the sub-parallel production well, in addition to receivers installed in the monitoring wells, to detect P- and S-wave arrivals. Over the summer, I picked all the P-wave arrivals and helped generate initial tomographic models. The 3D P- and S-wave velocity models associated with these are presented here with a discussion of the elastic parameters they imply. The rock is found to be more complicated and heterogeneous than expected. Velocity and calculated elastic moduli values are reasonable for crystalline rock. These elastic parameters are used for modeling and monitoring seismic hypocenters that are associated with fracture propagation during EGS stimulation activities.

Under effective compression, impingement of opposing rough surfaces of a fracture can force the walls of the fracture apart during slip. Therefore, a fracture’s surface roughness exerts a primary control on the amount of dilation that can be sustained on a fracture since the opposing surfaces need to remain in contact. Previous work has attempted to characterize fracture surface roughness through topographic profiles and power spectral density analysis, but these metrics describing the geometry of a fracture’s surface are often non-unique when used independently. However, when combined these metrics are affective at characterizing fracture surface roughness, as well as the mechanisms affecting changes in roughness with increasing slip, and therefore changes in dilation. These mechanisms include the influence of primary grains and pores on initial fracture roughness, the effect of linkage on locally increasing roughness, and asperity destruction that limits the heights of asperities and forms gouge. This analysis reveals four essential stages of dilation during the lifecycle of a natural fracture, whereas previous slip-dilation models do not adequately address the evolution of fracture surface roughness: (1) initial slip companied by small dilation is mediated by roughness controlled by the primary grain and pore dimensions; (2) rapid dilation during and immediately following fracture growth by linkage of formerly isolated fractures; (3) wear of the fracture surface and gouge formation that minimizes dilation; and (4) between slip events cementation that modifies the mineral constituents in the fracture. By identifying these fundamental mechanisms that influence fracture surface roughness, this new conceptual model relating dilation to slip has specific applications to Enhanced Geothermal Systems (EGS), which attempt to produce long-lived dilation in natural fractures by inducing slip.

Early thermal breakthrough is an issue of concern in the geothermal industry, especially with regard to engineered geothermal systems (EGS). Determination of the specific surface area (SSA) of the fluid/rock interface in an EGS is vital to predicting early thermal breakthrough. An approach to this problem involving the application of tracers with different sorption properties (lithium, bromide, and deuterium) is presented. Upon injection into a reservoir, these tracers react along the fluid/rock interface to varying degrees. The resulting breakthrough separation at the extraction well can be used to derive SSA by applying a modified form of the advection-dispersion equation. For proof of concept, field tests were conducted in a sandstone bedding-plane fracture near Chazy, New York. Results showed minimal breakthrough separation, indicating insufficient sweep of the fracture area, and that lithium was not an ideal tracer in this medium. However, a relative measure of SSA can still be derived.

Porosity is a fundamental characteristic of rock critical to its mechanical and hydrologic behavior, yet a study of the open and accumulated healed porosity of nine core samples from Newberry Volcano shows that different measurement methods produce significantly different estimates of pore volume and structure. This study compares traditional 2D point count, petrographic image analysis, and 3D x-ray Micro Computed Tomography (micro CT) measurement of porosity primarily derived from fracture slip and dilation. The set of measurements quantifies the discrepancy among measurement methods and provides a basis for assessing how this uncertainty depends on geologic factors including the stage of fracture development, and the size and connectivity of the pores. This comparison reveals that detailed petrographic mapping provides the most accurate characterization of fracture porosity, and its history of development, owing to its high spatial resolution and accuracy of phase identification as well as insights afforded from mineralogic and textural relationships. However, this analysis lacks the three-dimensional characterization necessary to determine pore shape and interconnectedness, especially in highly anisotropic and heterogeneous fracture porosity. Micro CT does characterize the three dimensionality of pores, and thus although it consistently underestimates porosity due to non-uniqueness of phase densities and limitations in resolution, and is difficult to post process, this method can usefully augment the petrographic analysis. High resolution mapping of petrographic thin sections also provides a means to characterize the roughness of fracture surfaces across multiple cycles of slip, related dilation, and healing. Analysis of 19 slip events on a small, early stage fracture experiencing less than mm-scale slip, indicates that this roughness is preserved across multiple slip events and is consistently associated with dilation recorded by the accumulation of layers of precipitated cement. Initially, characteristic length scales intrinsic to rock such as the primary grain and pore size distribution of the > 0.2 mm size fraction significantly influence the roughness of fractures, until the dominant mechanism of fracture growth becomes linkage among macroscopic fractures. This correlation among primary rock characteristics such as grain size, fracture roughness, repeated fracture slip, and dilation provides a potential method to assess the key attributes promoting dilatant, self-propping fracture slip necessary for successful stimulation to generate an Enhanced Geothermal System. Comparison to more developed fractures characterized by the development of fault rock suggest such stimulation is most successful for fractures sustaining small slip of a few millimeters or less during single slip events.

Cette étude porte sur des réservoirs souterrains, utilisés pour du stockage de gaz en cavités salines, et de la géothermie pour la production d’énergie. L’objectif est de développer une méthodologie avec la géodésie spatiale (InSAR et GNSS) pour extraire un maximum d’informations des déformations en surface issues des processus souterrains (variation de pression et de volume). Les zones végétalisées surplombant les réservoirs étudiés subissent une importante décorrélation temporelle, défavorable à une application efficace de l’InSAR. Les résultats montrent qu’il est possible d’extraire des déplacements pluri-millimétriques par la combinaison de ces deux techniques. Ce travail montre également que l’InSAR peut être utilisé comme outil d’alerte via un traitement rapide, compromis entre rapidité et précision. La disponibilité des données Sentinel-1 (gratuites) offre des perspectives de suivi inégalées en matière de résolution spatiale et temporelle, logistique, et économiqueThis study focuses on underground reservoirs, used for gas storage in salt caverns, and geothermal energy production. The objective is to develop a methodology using spatial geodesy (InSAR and GNSS) to extract a maximum of information from the surface deformation resulting from underground processes (pressure and volume variations). The vegetated areas overhanging the studied reservoirs are subject to significant temporal decorrelation, which is unfavourable for an efficient application of InSAR. The results show that it is possible to extract multi-millimeter displacements by combining these two techniques. This work also shows that InSAR can be used as a warning tool via fast processing, a compromise between speed and accuracy. The availability of Sentinel-1 data (free) offers unrivalled monitoring prospects in terms of spatial and temporal resolution, logistics and economics

Orientador: Guilherme de Paula NogueiraResumo: Comumente o biotipo é o principal critério utilizado para predicão da puberdade precoce em novilhas Nelore. Este experimento comparou os possíveis efeitos do peso a desmama (PeD), peso ao sobreano (PeS), espessura de gordura subcutânea na garupa (EGSG), concentrações séricas de IGF-I (IGF-I) e insulina ao sobreano (Ins), ganho diário de peso: até a desmama (GD), entre a desmama ao sobreano (GS) e do nascimento até o sobreano (GT), além de escores visuais de conformação (C), precocidade (P) e musculatura (M) avaliados tanto na desmama como no sobreano, sobre a idade à primeira prenhez e desempenho na primeira estação de monta (EM) de novilhas Nelore. Para isso foram utilizados dados de 241 novilhas, produzidos pela P@RM agropecuária, estas nascidas entre maio e setembro de 2016. As mesmas permaneceram à pasto num único lote a partir da desmama. Avaliações de CPM e mensuração do peso corporal em jejum alimentar e hídrico após12h foram realizadas na desmama e repetidas após ganho mínimo de 50kg de peso. Foi iniciada a EM no dia seguinte à avaliação de sobreano, quando as novilhas foram submetidas ao protocolo de indução de puberdade e duas inseminações artificiais em tempo fixo, e posterior repasse com touro. Para a idade em dias à primeira prenhes houve efeito individual de C na desmama, PeD, GD, P e M no sobreano, GS, GT e IGF-I (p<0,05), no entanto, P e M na desmama não se mostraram importantes (p>0,05).

Abstract: Lately frame has being used to predict the occurrence of precocious puberty in Nellore heifers. This experiment compared the possible effects of weaning weight (PeD), yearling weight (PeS), rump backfat thickness (EGSG), serum concentrations of IGF-I (IGF-I) and insulin to yearling (INS), daily weight gain until weaning (GD), between weaning to yearling (GS) and from birth to yearling (GT), further the visual scores of conformation (C), precocity (P) and musculature (M) on weaning and yearling, on age at first pregnancy and the performance in the first breeding season (EM) of Nellore heifers. For that, data from 241 animals, produced by P@RM farming, born between May to September 2016 was used. After weaning all heifers were kept on pasture in a single lot and CPM score and body weight gain, under restriction of food and water for 12 h, were evaluated at weaning and repeated after a minimum weight gain of 50 kg. Breeding season started a day after evaluation of yearling, where heifers were subjected to a puberty induction protocol and two fixed time artificial inseminations, followed by a clean-up bull. There was an individual effect of C at weaning, PeD, GD, P and M on the yearling, GS, GT and IGF-I on age at days at first pregnancy (p<0.05), however, the date of birth, P and M at weaning had no significant effect (p>0.05). All CPM evaluations showed positive correlations with GD, GS and GT both at weaning (r= 0.61, 0.38, 0.43, p<0.05) and yearling (0.46, 0.50, 0, 41, p<0.05...

Context. The reionization of the Universe is one of the most important topics of present-day astrophysical research. The most plausible candidates for the reionization process are star-forming galaxies, which according to the predictions of the majority of the theoretical and semi-analytical models should dominate the H I ionizing background at z greater than or similar to 3. Aims. We measure the Lyman continuum escape fraction, which is one of the key parameters used to compute the contribution of star-forming galaxies to the UV background. It provides the ratio between the photons produced at lambda <= 912 angstrom rest-frame and those that are able to reach the inter-galactic medium, i.e. that are not absorbed by the neutral hydrogen or by the dust of the galaxy's inter-stellar medium. Methods. We used ultra-deep U-band imaging (U = 30.2 mag at 1 sigma) from Large Binocular Camera at the Large Binocular Telescope (LBC/LBT) in the CANDELS/GOODS-North field and deep imaging in the COSMOS and EGS fields in order to estimate the Lyman continuum escape fraction of 69 star-forming galaxies with secure spectroscopic redshifts at 3.27 <= z <= 3.40 to faint magnitude limits (L = 0.2L*, or equivalently M-1500 similar to -19). The narrow redshift range implies that the LBC U-band filter exclusively samples the lambda <= 912 angstrom rest-frame wavelengths. Results. We measured through stacks a stringent upper limit (<1.7% at 1 sigma) for the relative escape fraction of H I ionizing photons from bright galaxies (L > L*), while for the faint population (L = 0.2L*) the limit to the escape fraction is less than or similar to 10%. We computed the contribution of star-forming galaxies to the observed UV background at z similar to 3 and find that it is not sufficient to keep the Universe ionized at these redshifts unless their escape fraction increases significantly (>= 10%) at low luminosities (M-1500 >= -19). Conclusions. We compare our results on the Lyman continuum escape fraction of high-z galaxies with recent estimates in the literature, and discuss future prospects to shed light on the end of the Dark Ages. In the future, strong gravitational lensing will be fundamental in order to measure the Lyman continuum escape fraction down to faint magnitudes (M-1500 similar to -16) that are inaccessible with the present instrumentation on blank fields. These results will be important in order to quantify the role of faint galaxies to the reionization budget.

As referências apresentadas e utilizadas através de métodos indutivos de propagação eletromagnética E.M., são utilizadas na prospecção de minerais, entre outros, haja vista que em regiões tropicais existem camadas superficiais condutivas (manto intemperismo) que levam a influenciar, evidentemente, na interpretação do resultado real. Em nossa região Amazônica, o manto apresenta-se bastante desenvolvido e condutivo. O objetivo deste trabalho é estudar os efeitos dos mantos sobre anomalias VLF, devidos a corpos tabulares inclinados em contato ou não com o manto (manto galvânico e manto indutivo). Deste modo, foram realizadas umas séries de experimentos em modelagens numéricas através da eGs, considerando-se diferentes parâmetros de resposta para o manto e para o corpo. Os trabalhos de modelagem numérica, bem como seus resultados foram apresentados por diversas situações, como: variação da profundidade do topo do condutor, variação do mergulho do condutor, variação da condutância do manto, entre outros. Para interpretação dos resultados, foi gerado um conjunto de curvas considerando-se valores pico-a-pico das anomalias de Tilt Angle e de Elipsidade. Os resultados foram sintetizados em um outro conjunto de curvas reunidas em diagramas de Argand. A medida em que se aumenta a profundidade, o pico-a-pico e a forma do pico da anomalia do Tilt Angle e da Elipsidade diminuem na presença do manto, ou na ausência do mesmo, fazendo com que este se afaste do ponto de “Cross-Over”. Para um condutor da mesma espessura, o aumento da condutância causa um aumento nas anomalias de Tilt Angle e da Elipsidade. O efeito geral na variação do mergulho do condutor é o de causar uma assimetria nos perfis de Tilt Angle e Elipsidade. O aumento da condutância do manto de intemperismo causa uma diminuição nas anomalias de Tilt Angle e de Elipsidade. Há rotação de fase no sentido anti-horário, sendo mais intensa para grandes valores de condutância do corpo. Na presença do manto, o corpo parece estar a uma profundidade inferior à verdadeira e, tendendo, a ser menos condutivo.
In this dissertation I have studied the effect of partially conducting overburden on the VLF anomalies of an underlying inclined conducting half-plane. In tropical climate, overburden is normally well developed due to climatic conditions. This study is realized through numerical modeling using finite elements and algorithms computing the results employing the eGs developed by Luiz Rijo of the Department of Geophysics of the Federal University of Pará, Brazil. In these numerical experiments two geoelectrical situations between the overburden and the underlying half-plane are considered: one when they are in galvanic contact called as “galvanic overburden” and the other when they are not in contact called as “inductive overburden”. The depth, dip and conductance of the half-plane is varied alongwith the conductance of the overburden in this study. The results are presented in the form of Tilt-Angle and Ellipticity profiles. The Ellipticity profiles are highly affected by the presence of both types of the conducting overburden. The minor positive and negative peaks in the central part of the profile disappear as the overburden conductance increases. Initially there is an enhancement in the ellipticity anomaly at the lower conductance of the overburden but then it decreases as the overburden conductance increases. However, the tilt-angle anomalies decrease monotonously. Also, in both the ellipticity and the tilt-angle profiles, the distance between the peaks become shorter due the overburden. Consequently, the target depth is interpreted as shallower than the real. The index of asymmetry, used to determine the dip of the half-plane, is also affected by the overburden. Therefore, the dip determination is hampered in the presence of the overburden. An anticlock wise rotation in Argand diagram due to increase in the overburden conductance, result in interpretation a target of less conductance than the real value. Therefore, the presence of the conducting overburden should be taken into the consideration during interpretation of the VLF anomalies.

In this thesis, the potential of enhanced geothermal system to provide adequate energy to a 10 MW electricity power plant from Prairie Evaporite Formation of Williston Basin was investigated. This formation partly consists of halite with low thermal resistance and high thermal conductivity, which translates into a lower drilling length to reach the desired temperature, comparing to other rock types.
To this end, two numerical models with experimental data in south-west Manitoba (i.e. Tilston) and south-east Saskatchewan (i.e. Generic) were designed. The thermal reservoirs were located at 1.5 km (Tilston site) and 3 km (Generic site) with approximate thicknesses of 118 m. Considering an injection brine of 6% NaCl at 15°C, the final derived temperature at wellhead of the production wells were 43°C and 105°C respectively.
Finally, the Generic site was concluded as a suitable candidate for electricity production by providing higher surfaced fluid temperature than the minimum of 80°C.February 2017

L’objectif de cette thèse est la réalisation d’un suivi géodésique des sites géothermiques de Soultz-sous-Forêts et de Rittershoffen (Alsace, France). Les observations permettent de faire un état des lieux des déplacements de surface des environs des sites pendant leur mise en place et apportent de nouvelles connaissances à l’échelle locale sur le Fossé rhénan supérieur. Les résultats majeurs concernent l’analyse des déformations observées à Landau (Rhénanie-Palatinat, Allemagne). Cette approche illustre également les complémentarités des méthodes géodésiques utilisées (InSAR, GNSS, nivellement)The Upper Rhine Graben benefits of natural circulation of geothermal fluid, which makes it suitable for geothermal exploitation. How and where do geothermal fluids circulate? What are their links with induced seismicity and tectonics? Could geodesy provide new insigth to these questions ? The objective of this thesis is the realization of a geodetic monitoring at Soultz and Rittershoffen (Alsace, France) geothermal sites. The results are an inventory of nearby sites surface displacements during the implementation of the geothermal sites. They bring new knowledge locally on the Upper Rhine Graben. The main results are the analysis of deformations observed in Landau (Palatinat, Germany). This approach also reflects the complementarities of geodetic methods (InSAR, GNSS, levelling)

Thesis (M.Sc. (Agric)) --University of Limpopo, 2010An experiment was conducted to determine the effect of egg weight on hatchability, hatch-weight and subsequent productivity of Venda chickens. A total of 360 Venda chicken eggs based on their weights were collected within one week and assigned to four treatments with five replicates of 18 eggs per replicate. A randomized design was used. The four treatment weights were below 49 g, between 50 and 59 g, between 60 and 69 g and above 70 g. the eggs were incubated for 21 days. The chicks were raised up to 13 weeks based on their treatments but fed a similar diet. Egg weight was positively and strongly correlated (r2 = 0.727) with hatchability. Similarly, egg weight was positively and strongly correlated (r2 = 0.0.953) with chick hatch-weight. Between one and seven weeks old, Venda chicks hatched from heavier eggs ate less (P< 0.05) than those hatched from lighter eggs. Heavier eggs hatched chicks with better (P< 0.05) feed conversion ratio. However, chicks hatched from heavier eggs tended to have higher (P< 0.05) live weight at seven weeks old than those hatched from lighter eggs. Heavier eggs tended to hatch chicks that had higher (P< 0.05) mortality rates. However, metabolisable energy and nitrogen retention of the chicks aged seven weeks was not (P> 0.05) affected by egg weight. Growth rate and live weight of the chicks aged between one and seven weeks were optimized at different Venda chicken egg weights of 56 (r2 = 0.514) and 60 (r2 = 0.870) g, respectively. Egg weight had no (P> 0.05) effect on metabolisable energy, feed conversion ratio, growth rate, live weight, carcass weight and carcass parts of Venda chickens aged between eight and 13 weeks except fat pad weight. Venda chickens hatched from lighter eggs had lower (P< 0.05) fat pad weights than those hatched from heavier eggs. Meat samples of chickens hatched from lighter eggs had higher (P< 0.05) nitrogen contents. It is concluded that Venda chicken egg weight affects (P< 0.05) egg hatchability, chick hatch-weight, growth rate, live weight and carcass characteristics of the chicken. However, these variables are optimized at different egg weights. This has implications on selecting eggs for incubation.

Thesis (MA.Agricultural Management (Animal Production)) -- University of Limpopo, 2013The objectives of the study were to evaluate the productivity of the Vhembe egg production project and determine the management and socio-economic factors affecting productivity. The data were collected from 2005 to 2007. Thirty-two farmers from four municipalities were randomly selected. Each household received a once-off unit consisting of a cage with eighteen point of lay chickens 4x50 bags of laying mesh, feeding and drinking troughs. Production records from sampled farmers were used in the analysis. Data included monthly egg production, eggs consumed, eggs sold, income from eggs, production costs, monthly feed utilization and mortality. Primary data on educational standards, socio-economic characteristics (age and gender of the household head, farming size, level of education and alternative income, were collected using a questionnaire. The study revealed that sex, age and educational level had impact on production as low production was associated with older farmers and low level of education. These factors should be considered when planning community projects. Chicken rearing and ownership is often shared among the family members, in this study, the management was predominantly by women (63%) and children (18%). This may be an indication that if assistance efforts are targeted towards women, village poverty could be significantly reduced. It is concluded that the low income accrued from the project explains the reason for high abandonment or neglect of the project. The income received from the project is smaller than the government grants and as such not attractive. It is not surprising that presently most farmers have abandoned the project. It is noted that if labour costs had been taken into consideration, the project would be running at a serious loss and the resultant output would discourage even the most enthusiastic farmers.

O presente trabalho consiste no desenvolvimento de uma interface gráfica para pré e pós-processamentos de dados elétricos e eletromagnéticos em geofísica utilizando-a na transformação da EGSLIB – Electrical Geophysics Software Library, a qual é constituída por um acervo de programas FORTRAN para DOS, em um software integrado e que possua uma eficiente interface gráfica com o usuário. O resultado deste esforço foi a surgimento de um produto que foi denominado EGS 2000 – Electrical Geophysics Suite - 2000 version. Construído em ambiente DELPHI da Borland, através de um processo de desenvolvimento que, além de orientado a objetos, foi centrado em uma arquitetura que permitiu um alto grau de aproveitamento de programas FORTRAN já desenvolvidos e testados. Tal produto, constitui-se em uma poderosa ferramenta de auxílio à modelagem e interpretação de dados geofísicos totalmente executável no sistema operacional MS-Windows. Com isso, alcançou-se uma forma economicamente viável para dar uma destinação prática aos resultados teóricos obtidos nas universidades e institutos de pesquisa. Os exemplos apresentados, mostram-nos que, auxiliadas por computador, modelagens e interpretações de dados geofísicos alcançam um nível de produtividade e versatilidade jamais obtidos pelas ferramentas de outrora, uma vez que diversos modelos podem ser armazenados e recuperados e seus resultados comparados com dados observados sistematicamente colecionados, conferindo ao processo um alto grau de confiabilidade e rapidez.

Much work in geothermal is focused on technologies that make deeper drilling more economical, no matter what types of geothermal power plants are. The most important of these problems are well drilling investment cost and energy conversion efficiency, and geological earthquakes problems that can be induced by using enhanced geothermal systems (EGS). The drilling cost and energy efficiency of geothermal are caused by drilling depth. So, finding solution to reduce drilling depth and risk are essential for geothermal development.
In this study, we analyze one possible geothermal power plant development method recycling abandoned coal mines which could saving well drilling cost and reducing geology surveying risk, the geothermal wells will be drilled at the bottom of the abandoned coal mines. Then we summarize present project recycling abandoned gas-oil wells for geothermal power plant development.
Based on Paris agreement and IPCC special report on 1.5°C, we analyze the situation of renewable and conventional energy to provide the reason why we have many abandoned coal mines and abandoned gas-oil wells to recycle, then we calculate geothermal power plant capacity using abandoned coal mines and using abandoned gas-oil wells.
In the second part of this study, we analyze the geothermal risk using EGS, as long as the reservoir rock using hydraulic fracturing, the geothermal risk is the induced earthquake which is caused by fracture propagation of the reservoir rock mass, the MRI (magnetic resonance image) experiments were conducted to obtain morphology of fracture propagation process of rock samples under uniaxial load stress to simulate reservoir rock failure process and measure rock fracture propagation velocity. The results show MRI could provide high quality image of rock fracture propagation process, rock fracture propagation velocity will start from low speed to high speed when approaching the maximum stress of rock.

The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients. The utilization rate of the forage for Lilluns egg was 47 %, the other egg producers in this study had an utilization rate between 45-50 %. The results showed that Lilluns egg had an excess of nitrogen of 0,04 kg/kg eggs. Lilluns egg also had an excess of phosphorus and potassium. The excess of phosphorus was 0,01 kg/kg eggs and 0,013 kg/kg eggs for potassium. The results showed that all the egg producers in this study had an excess of all the nutrients. The conclusion is that the egg production systems in this study have a similar utilization rate and the excess of nutrients per kg egg was also similar for all the egg producers.

The thesis deals with the front part stiffness of modern vehicles, especially for the use in the field of forensic engineering in the traffic accident analysis. During the traffic accident analysis, an inquiry into the collision between vehicles is carried out which is an integral part of determining the energy loss of the vehicle at the impact, or more precisely the deformation energy expressed in the form of Energy Equivalent Speed (EES). In case of known stiffness of given part of the vehicle and based on the depth of deformation, it is possible to calculate the deformation energy, or more precisely EES corresponding with given damage of the vehicle. In the field of forensic engineering, the values of stiffness of individual vehicle components are not known and therefore, alternative methods are used to calculate the EES, they are outlined in the research part of this dissertation. However, the current methods of EES determination have some limitations when it comes to usability, and therefore, new EES calculation for the front part of the vehicle was designed in the research. It was based on the real crash test results using real stiffness characteristics of the front part of a vehicle. The front part of the vehicle is divided into individual areas and each of these parts is characterised by its own stiffness coefficient. The designed EES calculation can thus be also used for collisions with partial overlapping, taking into account the real stiffness of the damaged part of the vehicle, which was not possible with existing methods. In the research part of this dissertation, a computer programme to calculate deformation energy and EES was processed. It works with individual stiffness characteristics in given areas where the input data are entered by the user and include the depth of permanent front part deformation in individual areas, vehicle weight, the direction of an impact force and the friction coefficient on the contact surface. Considering the fact that the vehicle stiffness is also one of the control parameters at solving collisions in the PC-Crash simulation programme, which is used in forensic engineering practice for the analysis of a collision process, a supplementary computer programme was designed. Based on the above-mentioned input data, the supplementary programme can further calculate data for collision solving in the simulation programme, namely stiffness, restitution coefficient and the vehicle damage stated in the output report of the simulation programme. Based on these data, the expert thus has the opportunity to solve the collision of two vehicles in the simulation programme with as much preciseness as if it was a real collision.

Повний текст джерелаАнотація:
The thesis explores the 'lived experiences' of egg share donors in the United Kingdom (UK) and in particular, has examined the extent to which they are able to consent to becoming an egg share donor. Specific emphasis was given to exploring the factors that motivated their decision-making in view of the criticism egg sharing schemes have met with since their emergence in the early 1990s. Egg sharing provides women who are themselves undergoing assisted reproduction treatment (ARTs) with the opportunity to share their eggs with up to two recipients(s). The donor‘s treatment costs are subsidised by the recipient(s). Thus some women are able to access cheaper, expeditious treatment. Advocates perceive the schemes as 'win-win'. Conversely, critics challenge egg sharing on both psychosocial and ethical grounds. The thesis conveys the accounts provided by a self-selected sample of seventeen women recruited via two online infertility support websites and a charitable organisation. Hermeneutic phenomenology and the voice-centered relational method (VCRM) of analysis were employed to assess women‘s motivations to donate and their ability to provide informed consent. Four asynchronous e-mail interviews and data collected from an online self-completion questionnaire were utilised in order to enable the experiences of egg share donors to be revealed. Drawing extensively upon philosophical, social anthropological, social philosophical, sociological, and social psychological literature, the study demonstrates the complexities associated with the decision to egg share within the context of the UK regulatory framework for ART provision. This includes existing empirical accounts of egg sharing. The thesis describes how it is one of the first to examine the experiences of egg share donors since the removal of donor anonymity in the UK in 2005. Significantly, it makes an original contribution to current understandings of the experiences, motivations, ability to consent, and post-treatment implications for egg share donors.

Notre travail de these a consiste a identifier les proteines codees par les clones eg2 et eg3. Ces adnc correspondent a des arnm specifiquement desadenyles apres la fecondation chez le xenope. Le sequencage de ces deux adnc nous a permis de constater que les sequences qui en sont deduites presentent l'ensemble des motifs caracteristiques retrouve dans les sous-domaines du domaine catalytique des proteines kinases. L'analyse de la sequence des sous-domaines 6b et 8 nous permet de supposer que ces molecules seraient potentiellement des serine/threonine-kinases. L'interrogation des banques de donnees proteiques nous a permis de constater que la sequence du domaine catalytique de la proteine eg2 presentait la similitude la plus elevee avec le domaine catalytique de l'une des sous-unites catalytiques de la proteine kinase a identifiee chez s. Cerevisiae. Pour eg3, le domaine catalytique presente un pourcentage de similitude superieur a 50% avec la sequence du domaine catalytique de la proteine kinase bkin2 identifiee chez h. Vulgare. Dans cette derniere, le domaine catalytique est excentre du cote de l'extremite nh2 de la molecule ce qui correspond a une position peu frequente dans la famille des serine/threonine kinases. Nous avons mis en evidence deux adnc (eg2a et eg2b) codant pour des proteines dont l'identite est de 94,4%. Nous avons prepare un serum polyclonal dirige contre une region specifique de la proteine eg2. Ce dernier nous a permis de constater que la proteine est presente des le debut de l'ovogenese et subsiste au moins jusqu'au stade bourgeon caudal. De plus, nous avons montre que la proteine eg2 est majoritairement synthetisee pendant la maturation ovocytaire. Ceci est en correlation avec la polyadenylation de l'arnm qui a lieu au cours de cette meme phase de l'ovogenese. La proteine est localisee au niveau des poles du fuseau mitotique

In order to increase the efficiency of diesel particulate filter regeneration more knowledge about diesel soot and its reactivity is required. This thesis compares soot created during accelerated filter loading by lowered rail pressure, with soot from normal filter loading. Soot properties and their correlations to oxidation reactivity are also examined through thermogravimetric analysis, scanning electron microscopy, energy dispersive x-ray spectroscopy, BET nitrogen sorption, and FTIR spectroscopy. The usefulness of these analysis methods was also evaluated. The soot samples consisted of two carbon blacks for reference (Printex U and Vulcan XC 72), four accelerated soot samples and two non-accelerated samples. The results showed that the accelerated samples contained less volatile organic compounds than the non-accelerated soot and required slightly higher temperatures to oxidize in air. Soot with a high oxygen/carbon ratio and high levels of volatile organic compounds was found to be the most reactive. The most useful method for analyzing the soot was the thermogravimetric analysis. The scanning electron microscopy and energy dispersive x-ray spectroscopy were useful additions but the FTIR spectroscopy provided very little useful information. The usefulness of BET nitrogen sorption was not decisively concluded.För att kunna förbättra regenereringen av dieselpartikelfilter krävs en ökad kunskap om dieselsot och dess reaktivitet. I detta examensarbete jämförs sot som skapas vid accelererad sotinlagring genom sänkt railtryck, med sot från normal sotinlagring. Hur sotets egenskaper påverkar dess reaktivitet undersöks också genom termogravimetrisk analys, svepelektronmikroskopi, energidispersiv röntgenspektroskopi, BET-kväveadsorption och FTIR-spektroskopi. Hur väl dessa analysmetoder lämpar sig för analys av sot utvärderades också. Sotproverna utgjordes av två så kallade ”carbon black” för referens (Printex U och Vulcan XC 72), fyra accelererade sotprov och två icke-accelererade prov. Resultaten visade att de accelererade proverna innehöll mindre flyktiga organiska föreningar än icke-accelererade sot och krävde något högre temperaturer för att oxideras i luft. Sot med ett högt syre/kol-förhållande och höga nivåer av flyktiga organiska föreningar visade sig vara mest reaktivt. Den mest användbara metoden för att analysera sot var den termogravimetriska analysen. Svepelektronmikroskopi och energidispersiv röntgenspektroskopi var användbara som komplementerande metoder men FTIR-spektroskopi gav väldigt lite användbar information. Ingen konkret slutsats drogs gällande nyttan av BET-kväveadsorption.

O experimento teve por objetivo estudar o efeito de níveis de cálcio e da granulometria do calcário sobre o desempenho, qualidade de ovos e teor de cálcio no sangue e fezes de poedeiras semipesadas. As aves foram distribuídas em um delineamento fatorial inteiramente casualisado (3x4) com 12 tratamentos com quatro níveis de cálcio (3,0; 3,5; 4,0 e 4,5 %) e três composições granulmétricas do calcário: 100 % fino (0,18 mm); 50 % fino (0,18 mm) e 50 % grosso (3,13 mm) e 30 % fino (0,18 mm) e 70 % grosso (3,13 mm), seis repetições de oito aves por unidade experimental da linhagem Hisex Brown® de 59 a 70 semanas de idade. Não se observaram diferenças entre os tratamentos nem interações entre os fatores para percentagem postura, peso médio dos ovos, massa de ovos, consumo de ração conversão alimentar por dúzia e por quilograma de ovos produzidos, percentagem de ovos quebrados, percentagem de ovos inteiros, gravidade específica, espessura de casca, percentagem de casca, peso da casca por superfície de área, percentagem de gema, coloração da gema, % de albume, unidade Haugh e quantidade de cálcio no sangue. Observou-se efeito quadrático da composição granulométrica de calcário para percentagem de ovos defeituosos, com menor percentagem de ovos defeituosos usando composições granulométricas do calcário formado de 61,75 % de calcário de granulometria fina e 38,25 % de calcário de granulometria grossa. Houve efeito linear da equação de regressão do nível de cálcio da dieta para peso da casca por superfície de área e cálcio nas fezes onde a elevação no nível cálcio dietético aumentou o peso da casca por superfície de área e a percentagem de cálcio excretado. Conclui-se que a combinação do maior nível de cálcio (4,5%) na dieta com substituição do calcário fino pelo grosso em 38 % na alimentação de poedeiras...

The accurate identification of parasites allows for the quick diagnosis and treatment of infections. Current state-of-the-art identification techniques require a trained technician to examine prepared specimens by microscope or other molecular methods. In an effort to automate the process and better facilitate the field identification of parasites, approaches are developed to utilize LabVIEW and MATLAB, which are commercially available image processing software packages, for parasite egg identification. The goal of this project is to investigate different image processing techniques and descriptors for the detection and characterization of the following parasite eggs: Ascaris lumbricoides, Taenia sp., and Paragonimus westermani. One manual approach and four automated approaches are used to locate the parasite eggs and gather parasite characterization data. The manual approach uses manual measurements of the parasite eggs within the digital images. The four automated approaches are LabVIEW Vision Assistant scripts, MATLAB separation code, MATLAB cross-section grayscale analysis, and MATLAB edge signature analysis. Forty-four separate measurements were analyzed through the four different approaches. Two types of statistical tests, single factor global Analysis of Variance (ANOVA) test and Multiple Comparison tests, are used to demonstrate that parasite eggs can be differentiated. Thirty-six of the measurements proved to be statistically significant in the differentiation of at least two of the parasite egg types. Of the thirty-six measurements, seven proved to be statistically significant in the differentiation of all three parasite egg types. These results have shown that it is feasible to develop an automated parasite egg detection and identification algorithm through image processing. The automated image processing techniques have proven successful at differentiating parasite eggs from background material.

From 1988 to 1992, 66% of all food-borne illnesses caused by salmonella enteritidis involved eggs or foods containing eggs. Contamination of eggs may occur on the inside as well as the outside of the shell. This article outlines the proper refrigeration, cooking and handling methods to prevent most egg safety problems.

Resumo: O experimento teve por objetivo estudar o efeito de níveis de cálcio e da granulometria do calcário sobre o desempenho, qualidade de ovos e teor de cálcio no sangue e fezes de poedeiras semipesadas. As aves foram distribuídas em um delineamento fatorial inteiramente casualisado (3x4) com 12 tratamentos com quatro níveis de cálcio (3,0; 3,5; 4,0 e 4,5 %) e três composições granulmétricas do calcário: 100 % fino (0,18 mm); 50 % fino (0,18 mm) e 50 % grosso (3,13 mm) e 30 % fino (0,18 mm) e 70 % grosso (3,13 mm), seis repetições de oito aves por unidade experimental da linhagem Hisex Brown® de 59 a 70 semanas de idade. Não se observaram diferenças entre os tratamentos nem interações entre os fatores para percentagem postura, peso médio dos ovos, massa de ovos, consumo de ração conversão alimentar por dúzia e por quilograma de ovos produzidos, percentagem de ovos quebrados, percentagem de ovos inteiros, gravidade específica, espessura de casca, percentagem de casca, peso da casca por superfície de área, percentagem de gema, coloração da gema, % de albume, unidade Haugh e quantidade de cálcio no sangue. Observou-se efeito quadrático da composição granulométrica de calcário para percentagem de ovos defeituosos, com menor percentagem de ovos defeituosos usando composições granulométricas do calcário formado de 61,75 % de calcário de granulometria fina e 38,25 % de calcário de granulometria grossa. Houve efeito linear da equação de regressão do nível de cálcio da dieta para peso da casca por superfície de área e cálcio nas fezes onde a elevação no nível cálcio dietético aumentou o peso da casca por superfície de área e a percentagem de cálcio excretado. Conclui-se que a combinação do maior nível de cálcio (4,5%) na dieta com substituição do calcário fino pelo grosso em 38 % na alimentação de poedeiras...
Abstract: The experiment was randomized with the objective to study the effect of the calcium levels and the limestone particle size on the performance, eggs quality and content of calcium in the blood and excrements in Brown laying hens. The birds had been distributed in an factorial delineation entirely randomized (3X4) with 12 treatments with four calcium levels (3.0, 3.5, 4.0 and 4.5 %) and three limestone particicle size compositions: 100 % thin (0.18 mm); 50 % thin (0.18 mm) and 50 % coarse (3.13 mm) and 30% thin (0.18 mm) and 70 % coarse (3.13 mm), six repetitions for treatment and eight birds for experimental unit of the Hisex Brown® lineage of 59 the 70 weeks of age. There were no differences (p>.05) for the treatments and nor significant interaction between the factors for posture percentage, average weight egg, egg mass produced, feed intake, feed conversion for dozen and kilogram of produced eggs, broken egg percentage, perfect egg percentage, specific gravity, shell thickness, eggshell and eight birds for experimental unit of the Hisex Brown® lineage of 59 the 70 weeks of age.

Thesis (M.Dev.) --University of Limpopo, 2011Poverty among communities is not a static condition. There are many factors which contribute to its causes and depth. In South Africa, the economic gaps imposed by the previous apartheid government aggravated economic inequalities and caused considerable disparities, which resulted in the high unemployment rates. This led to a call for pro-active initiatives by post 1994 democratic government to remedy the living condition of the previously disadvantaged people. As part of its poverty relief drive, the South African government has embarked on a series of developmental initiatives to bring services to the poor and to reduce enormous prevailing backlogs, with the aim of increasing community participation and improving the lives of the poor. This study evaluates the egg layers project as a poverty alleviation effort within Blouberg Municipality of the Limpopo Province to respond to the prevailing poverty and underdevelopment among the poor communities. This study revealed from the observations, interviews conducted and questionnaires administrated to sampled beneficiaries of Blouberg Municipality who faces poverty. The study formulated strategies and made recommendations regarding the impact and implementation of the egg layers on poor people.

Thesis (MSc. Agriculture (Animal Production)) -- University of Limpopo, 2015Three experiments were conducted to determine the effect of in ovo glucose injection on egg hatchability, chick hatch-weight, productivity and carcass characteristics of indigenous Potchefstroom koekoek chickens. A complete randomized design was used in all the three parts of the study (from incubation, 1-49 days old unsexed chickens and 50-91 days old female chickens). On day 18 of incubation the developing eggs were subjected to the following treatments: 0- (no glucose or water injected), 0+ (only water injected), 5, 10, 15 or 20 mg of glucose per egg. Each treatment had three replications and there were 20 eggs per replicate. A quadratic model was used to determine in ovo glucose injection levels for optimal egg hatchability, chick hatch-weight and chick to egg weight ratio of Potchefstroom koekoek chickens. In ovo glucose injection improved (P<0.05) egg hatchability, chick hatch-weight and chick to egg weight ratio of the chickens. Egg hatchability, chick hatch-weight and chick to egg weight ratio Potchefstroom koekoek chickens were optimized at different injection levels of 4.50, 10.43 and 12.00 mg of glucose per egg, respectively. Unsexed day-old chicks from the first experiment (according to their initial treatments and replicates) were used in a complete randomized design having six treatments, replicated three times, and having ten birds per replicate. Glucose injection levels increased (P<0.05) feed intake, growth rate, feed conversion ratio, live weight, metabolisable energy and nitrogen retention of female Potchefstroom koekoek chickens aged 1 to 49 days. However, growth rate, live weight, metabolisable energy intake and nitrogen retention of the chickens were optimized at glucose injection levels of 3.92, 4.36, 10.67 and 13.50 mg per egg, respectively. Female chickens from the second part of the study (according to their initial treatments and replicates) were used in a complete randomized design having six treatments, replicated three times, and having five birds per replicate. In ovo glucose injection levels improved (P<0.05) on feed intake, growth rate, feed conversion ratio, live weight, metabolisable energy and nitrogen retention of female Potchefstroom koekoek chickens aged 50 to 91 days. However, only feed conversion ratio and metabolisable energy intake of the chickens were optimized at glucose injection levels of 12.15 and 5.57 mg per egg, respectively. Injection level also improved (P<0.05) carcass, breast, v drumstick, thigh, wing, gizzard and liver weights of female Potchefstroom koekoek chickens aged 13 weeks. In ovo glucose injection increased (P<0.05) breast meat tenderness, juiciness and flavour of female Potchefstroom koekoek chickens aged 91 days. However, breast tenderness, juiciness and flavour of female Potchefstroom koekoek chickens were optimized injection levels of 13.50, 19.25 and 10.83 mg of glucose per egg, respectively. No chicken deaths were observe

This thesis explores the nature of the ego, drawing upon Christian and secular conceptions, in order to determine whether it is something to be affirmed or denied. Contemporary perspectives which either overvalue the individual self, or retort by refuting it, are questioned in the light of psychology, spirituality and Christian doctrine. I have been vexed by the existence of two seemingly opposing views within Christian popular culture. Those who look to the mystical tradition, the Spirituality of the Desert, claim that self-denial is the path to spiritual enlightenment and discovery of the true self; the ego is a false self. By contrast, the world of psychology endorses the merits of a healthy ego. Accordingly, psychology has made a significant contribution to pastoral theology and the life of church communities, especially in relation to personality dynamics. I seek to overcome this dichotomy through a broadening of our understanding of the self and adoption of the notion of personhood arising from a theological anthropology, which includes a relational understanding of imago Dei, Christological kenosis and the social doctrine of the Trinity. Findings are related to the paradoxical demand of Christian discipleship, encapsulated by Jesus’ teaching that his followers must lose themselves in order to be save themselves. The thesis concludes with a more practical turn, applying the insights of the earlier psychology and spirituality chapters, to assess tools for daily life for enhancing emotional and spiritual intelligence, which are taken as interdependent. The goal is for the ego to become servant, not master. The overall approach is a theoretical interdisciplinary one, drawing on the perspectives of philosophy, sociology, psychology, spirituality and theology, in order to gain a comprehensive picture of the ego.

Vitelline membrane strength plays a role in preventing contamination of albumen by yolk during separation and is important to food safety. Two experiments were conducted to determine if a relationship exists between vitelline membrane protein banding patterns, interior egg quality, and vitelline membrane rupture strength. Eggs were gathered from commercial egg producers from pre-molt (26 wk or 72 wk) and post-molted (74 wk or 82 wk) hens. In each of two trials twenty-one eggs were gathered and stored (4°C) per experiment. Three eggs were evaluated on days 0, 7, 14, 21, 28, 35, and 42 for eggs from pre-molted hens; and 1, 7, 14, 21, 28, 35, and 42 for eggs from molted hens for changes in SDS-PAGE protein banding patterns. The yolk from each egg was isolated and rolled on a wet paper towel to remove adhering albumen. The yolk was emptied and washed. The whole membrane was placed into double deionized water and divided into two sections. The first section was the whole membrane sample and the other was separated by forceps into inner and outer membrane samples. The three sections were dissolved separately in 1% SDS/70 mM Tris/HCl, pH 6.8. Protein concentration was determined using the Lowry method and proteins separated on 4-20% gradient gel by SDS-PAGE. Protein banding patterns were analyzed using the Bio-Rad Multi-Analyst Densitometer. Reductions of VMO I and GP II occurred along with reductions in the protein bands between 60 to 100 kDa.
In each of two trials, an additional one hundred forty eggs were gathered at the same time from the same flock and stored at 4°C. Twenty eggs were evaluated for quality on days 0, 7, 14, 21, 28, 35, and 42 for eggs from pre-molted hens; and 1, 7, 14, 21, 28, 35, and 42 for eggs from molted hens. Yolk index, albumen height, albumen pH, and yolk pH were determined. Vitelline membrane strength was determined using a compression anvil. Two different treatments were used on the yolk when evaluating rupture strength: 10 egg yolks with inner thin albumen layer, and 10 egg yolks rolled on wet paper towel to remove inner thin albumen layer. Interior egg quality and vitelline membrane strength declined during storage.

Copepods play a key role in the marine ecosystem where they form a vital trophodynamic link between primary and tertiary producers, and are the dominant prey of many marine fishes during their larval stage. Because of their naturally high nutritional quality, copepods are excellent alternatives to traditional live feed organisms for intensive marine fish production. For aquaculturists, it is important to have continuous access to live feed organisms when rearing altricial fish larvae. Cold stored subitaneous copepod eggs are highly relevant as inoculum for culturing live food.In the present study, the effects of light, salinity and short-term elevations in temperature on the 48-h hatching success (HS, %) of cold stored (2 °C) A. tonsa eggs were evaluated. A light experiment exposed the eggs to three different environments with respect to light for a period of up to 7.5 months; one treatment exposed the eggs to an artificial light source, the second treatment had eggs stored in complete darkness, and the third treatment had eggs stored under the storage conditions applied at NTNU Sealab (SSC-treatment). A salinity experiment stored eggs in seawater of four different salinities (34, 50, 75 and 100 ) for a period of up to 7.5 months to evaluate if this was beneficial for long-term cold storage of A. tonsa eggs. A short-term temperature elevation experiment was conducted in order to simulate shipping conditions with insufficient cooling for consignments of A. tonsa eggs. Cold stored eggs were exposed to temperatures elevated to 9 and 17 °C for 12 and 24 hours, with and without oxygen present in the storage media, whereupon they were put back in cold storage for a period of one week before determining the HS.The results for the light experiment showed that light had a profound negative effect on the HS of the cold stored A. tonsa eggs. No hatching was observed for eggs that were stored under constant light after 3 months of cold storage. Eggs stored in darkness showed a significantly higher HS at the final sampling of month 7.5 compared to the SSC treatment, and less dispersion in HS between the replicates throughout the experiment. The salinity experiment showed that the eggs could be stored in seawater with a salinity of 50 for up to 3 months with a high HS, whereas storage in seawater of 75 and 100 showed a low HS for most samplings and thus proved as a poor cold storage media. The short-term elevation in temperature experiment showed that the HS was significantly affected by the oxygen concentration in the seawater upon a cold storage period of 3 weeks, and that short-term elevations in temperature, up to 17 °C for a duration of 24 hours, did not significantly affect the HS when hatched one week after the onset of incubation. The viability of the hatched nauplii post temperature exposures was assessed in a feeding incidence experiment. It showed that neither of the conducted temperature elevations utterly inhibited the nauplii from feeding.
