Повний текст джерелаENGLISH ABSTRACT: The production and export of ostrich meat from southern Africa, to especially the European Union, are increasing rapidly due to the healthy nature of ostrich meat. The European Union has very high standards when importing food products, and it is inevitable that more emphasis is being placed on the production of high quality ostrich meat. Another aspect also of concern to consumers, is the welfare of animals prior to slaughter, and this forces producers to look at ways to decrease stress of animals during the ante-mortem period. Research regarding the effect of stress during the ante-mortem period, and as a result, on meat quality, haematology and weight loss in ostriches, is lacking and thus the purpose of this study was to investigate the effect of various transport distances, travel conditions and different birds on these factors. Ante-mortem stress was measured using serum corticosterone levels (ng/ml), heterophil: lymphocyte (H:L) ratio, white blood cell (WBC) count, aspartate aminotransferase (AST) and creatine kinase (CK), as well as the rate and extent of pH decline in the M. gastrocnemius. Special emphasis was also placed on the meat quality parameters drip loss, cooking loss, colour and Warner-Bratzler shear force (kg/1.27 cm diameter). Live weight losses, as well as carcass weight and weight of bruises cut off from each bird were also recorded during various stages of the trials. The effect of transport distance on the meat quality of ostriches was investigated. Ultimate pHu measurements were taken at 24 hours post-mortem. The muscles of the ostriches from the control group (i.e. birds that were not transported prior to slaughter) had a lower mean pHu (5.77 ± 0.053) than birds that travelled 60 (5.93 ± 0.053) and 600 km (6.11 ± 0.053), respectively. Differences in meat drip loss percentage were also observed between the three treatments. The birds in the control group (0.40 ± 0.07 %) had the lowest meat drip loss percentage compared to the birds that travelled 60 km (treatment C) (1.36 ± 0.07 %) and 600 km (treatment B) (0.97 ± 0.07 %), respectively, to a commcerical ostrich abattoir. Ostriches that were transported for 600 km (8.13 ± 1.16 %) had a greater percentage live weight loss during the antemortem period than birds that travelled a distance of 60 km (2.4 ± 2.185 %) to the abattoir, although both groups were deprived of feed for the same period. When the haematology of the groups that travelled different distances was compared at various time intervals in the ante-mortem period, both groups of birds experienced significant increases in WBC, s-AST and s-CK. An increased H:L ratio from pre-transport to post-transport was only evident in the birds that travelled 600 km (treatment B). However, the birds that travelled 60 km were the only group of birds that had significant elevated serum corticosterone levels during the ante-mortem period. The increase in the various blood parameters indicates severe physical stress, which negatively affected meat quality. Another trial also investigated the effect of various farming systems and transport on meat quality and bruising of ostrich carcasses. Ostriches were raised in three different farming systems, i.e. feedlot -, semiintensive - and free range conditions. Other factors that could maybe impact on stress susceptibility, such as road conditions, floorspace and floor type were also investigated. A significant difference in meat pHu was found between ostriches that were raised in a feedlot (5.95 ± 0.018) and semi-intensive (6.04 ± 0.033) environment. The feedlot birds also had the greatest percentage of carcass weight removed due to bruising. The free range birds were the birds that had the lowest floor density per birds and also had the least amount of bruising on their carcasses. Incidently the other two groups (feedlot and semi intensive) were the birds that travelled on the same type of road (mountain pass) in a truck with rubber flooring whilst the free range birds travelled on a straight road in trucks with metal grid floors.The results indicate that the type of farming system didn’t have a significant influence on meat quality of ostriches, but that factors such as road conditions, flooring and bird density did play a significant role in the incidence of bruises and injuries obtained during transport.
AFRIKAANSE OPSOMMING: Die produksie en uitvoer van volstruisvleis vanuit suidelike Afrika, na veral die Europese Unie, is gedurig aan die toeneem as gevolg van die gesonde aard van volstruisvleis. Die Europese Unie het baie hoë standaarde wanneer dit kom by die invoer van voedselprodukte en dit is onvermydelik dat meer klem op die produksie van hoë gehalte volstruisvleis gelê word. ʼn Ander aspek wat ook kommer wek by verbruikers is die welstand van diere voor slagting en hierdie aspek noodsaak produsente om te kyk na maniere om stres te beperk tydens die periode voor slagting. Navorsing rakende die effek van stres tydens die ante-mortem periode, asook vleiskwaliteit, hematologie en gewigsverlies in volstruise as gevolg van vervoer, ontbreek. Die doel van die studie was dus om die invloed van verskillende vervoerafstande, vervoersomstandighede en tipe produksiesisteme op volstruise se stresrespons te ondersoek. Die omvang van ante-mortem stres is bepaal deur die serum-kortikosteroon vlakke (ng/ml), heterofiel: limfosiet (H:L) ratio, witbloedsel (WBS) telling, aspartaat aminotransferase AST en creatien kinase CK, asook die tempo en vlak van pH-daling in die M. gastrocnemius, te meet. Spesiale klem is gelê op die vleisgehalte parameters kookverlies, drupverlies, kleur en Warner-Bratzler-skeurwaardes (kg/1.27 cm deursnee). Gewigsverlies is aangeteken op verskillende stadiums tydens die proewe. Karkasgewigte en die hoeveelheid gewig afgesny van elke volstruiskarkas a.g.v. kneusings is ook bepaal. Die eerste studie het die invloed van vervoerafstand op vleiskwaliteit van slagvolstruise ondersoek. Vleis kwaliteit parameters soos pH, drip verlies, kook verlies, taaiheid en kleur is ondersoek. Die pHu metings is op 24 uur post-mortem geneem. Slagvolstruise in die kontrole groep (d.i. -volstruise wat nie voor slagting vervoer is nie) het ’n laer vleis pHu (5.77 ± 0.05) gehad as voëls wat onderskeidelik 60 km (5.93 ± 0.05) en 600 km (6.11 ± 0.05) ver vervoer is. Verskille in persentasie dripverlies is gesien tussen die vleis van die voëls wat nie vervoer is nie (0.40 ± 0.07 %) en die voëls wat 60 km (1.36 ± 0.07 %) en 600 km ver (0.97 ± 0.07 %) onderskeidelik vervoer is. Volstruise wat vir 600 km (8.13 ± 1.16 %) vervoer is, het ‘n groter persentasie lewende gewig tydens die ante-mortem periode as voëls wat 60 km (2.4 ± 2.19 %) ver vervoer is na die abattoir, verloor, al was beide groepe weerhou van voer vir dieselfde tydperk. Beide groepe wat vervoer is (60 en 600 km) het merkbare toenames in witbloedsel (WBS) tellings, s-AST’s en s-CK’s getoon tydens die ante-mortem periode. Daar is slegs ʼn toename in H:L ratio (ʼn indikator van stres) van voor vervoer tot na vervoer gesien in die voëls wat 600 km vervoer is. Daarteenoor was die voëls wat slegs 60 km vervoer is die enigste voëls wat ʼn toename in korticosteroon vlakke getoon het gedurende die ante-mortem periode. Die toenames is heel moontlik ‘n aanduiding van erge fisiese stres wat ‘n negatiewe effek op vleiskwaliteit het. Die tweede studie het die effek van verskillende produksiesisteme en die stress respons van die verskillende groepe slagvolstuise op vervoer ondersoek. Vleis kwaliteit parameters soos pH, drip verlies, kook verlies en taaiheid is ondersoek. Die hoeveelheid kneusings per volstruis is ook gemeet. Daar was ‘n beduidende verskil (P = 0.009) tussen die pHu van die voerkraal (5.95 ± 0.018) en semi- intensiewe (6.04 ± 0.033) volstruise. Die voerkraal volstruise se vleis het die grootste drip- en kookverliese gehad in vergelyking met die ander twee groepe (semi-intensiewe en ekstensiewe) terwyl die ekstensiewe volstruise die taaiste vleis gehad het. Die voerkraalvoëls het ook die grootste persentasie karkasgewig verloor a.g.v. kneusings wat afgesny is. Die ekstensiewe voëls het die laagste vloer digtheid per volstruis gehad asook die minste kneusings. Die ander twee groepe (voerkraal en semi intensief) was die groepe wat op dieselfde pad vervoer is (bergpas) in vragmotors wat rubber vloere gehad het terwyl die ekstensiewe voêls op ‘n reguit pad vervoer is in ‘n vragmotor met ‘n metaal oppervlakte. Die resultate van die studie is ‘n aanduiding dat die tipe plaassisteem nie ‘n groot impak op die hoeveelheid akute stres ervaar deur die voëls tydens vervoer gehad het of gevolglik op die vleiskwaliteit van die volstruise nie, maar dat faktore soos pad toestand, tipe vloer en voëldigtheid wel ‘n wesenlike rol speel in die voorkoms van kneusings en beserings opgedoen tydens vervoer.

Повний текст джерелаTiivistelmä Melu aiheuttaa sotilaille palautumattoman kuulovaurion riskin, minkä vuoksi meluvammojen ehkäisy on tärkeää. Yksilöiden meluvamma-alttiudessa tiedetään olevan suuria eroja. Syytä tähän ei vielä kovin hyvin tunneta. Tämän laajan rekisteritutkimuksen aineisto koostui 1941 sotilaan terveystarkastustiedoista, kuulontutkimustuloksista ja työhistoriatiedoista. Tutkimuksessa selvitettiin meluvammojen esiintyvyyttä ja vaikeusastetta vuosina 1965−2007 palvelleilla suomalaisilla ammattisotilailla vertailemalla vuosikurssin ja aselajin mukaan valittuja ryhmiä sekä tutkittiin sotilaiden sydän- ja verisuonisairauksien riskitekijöiden ja meluvammojen yhteyttä. Lisäksi tarkasteltiin Suomen puolustusvoimissa ja Rajavartiolaitoksessa toteutettujen kuulonsuojelutoimenpiteiden vaikuttavuutta. Melu osoittautui olevan merkittävin kuulovian riskitekijä tutkitussa aineistossa. Viidentoista palvelusvuoden jälkeen ilmenneiden meluvammojen (kuulokynnys taajuudella 3,4 tai 6 kHz > 40 dB) määrä oli vähintään kymmenen prosenttiyksikköä pienempi sotilailla, jotka aloittivat uransa 1990-luvulla verrattuna vanhempien vuosikurssien sotilaisiin. Samanaikaisesti korkeiden äänien kuuloviat lievenivät noin 20 dB:n verran. Meluvammariski oli pienin lentäjillä, soittajilla ja laivastosotilailla ja suurin pioneereilla ja ilmatorjuntasotilailla. Sydän- ja verisuonisairauksien riskitekijöistä ainoastaan korkea verensokeri näytti selkeästi liittyvän kohonneeseen meluvammariskiin. 1980-luvun lopulla toimeenpantujen kuulonsuojelutoimenpiteiden ja sotilaiden kuulon parantumisen välillä on nähtävissä selkeä ajallinen yhteys. Suomessa 1970-luvulta lähtien käytetyssä neliportaisessa kuuloluokituksessa ja siihen tukeutuvissa käytännöissä ilmeni puutteita, joiden vuoksi suomalaisen työterveyshuollon kuulonhuoltoa koskeva ohjeistus on aiheellista tarkistaa

The library festival was a week of events and activities to promote the library and its space in new ways. It was a good way to remind staff and students of the value of libraries, not only as places to learn but also as places to enhance our leisure and working lives ... we chose to promote the database `Land of Lost Content¿. This was because graphic design and art students are based at our campus and we also thought this database would attract a wide range of students who might otherwise think that electronic databases contain little of interest for them. Our promotion has been so successful in many ways that we would like to share our experience with other librarians.

"Är det möjligt att uppnå kraven för FEBY Guld oavsett en byggnads placering i Sverige? : Is it possible to meet the requirements for FEBY Gold regardless of location in Sweden?" Thesis, Örebro universitet, Institutionen för naturvetenskap och teknik, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:oru:diva-82741.
Повний текст джерелаIn the current political climate, several measures are implemented to prevent climate change both in Sweden and internationally. ‘Forum för Energieffektict Byggande’, FEBY, is an 6rganization that aims to contribute to the development and expansion of low-energy buildings. To this end, FEBY has created a certification scheme to help contractors develop buildings with lower energy consumption. To certify a building, the contractor must ensure that certain requirements are met, for example heat loss figures. Since the conception of the certification, only about 50 small houses have been certified. This raises the question of why so few small houses have been certified, and whether this is due to how the requirements are set.The purpose of this report is to investigate whether the heat loss figures that features in FEBY’s certification are reasonable in reference to the construction of small houses regardless of its location in Sweden. To examine this, this study features small house construction in Lund, Falun, and Boden. The overall building design is the same in all three locations, apart from the insulation thickness in the outer wall. The examined parameters for this study include window glass area, U-value of windows, air leakage, and thermal bridges varied in the calculations to ensure a more relevant and reliable result.This study is based on the calculations referred to in the document named FEBY18 which is based on the requirements for heat loss figures according to the FEBY Gold level.The report is limited to a single-floor house of 100 m2 of heated floor area. Factors such as sound, sun, moisture, annual heat factor, or heat balance for air-heated buildings are not considered. Nor is bearing capacity, resistance to fire, or the position of the windows, considered within the study.The result shows that negative U-values occur in several parameter variations in Boden and Falun. Negative U-values indicate that the outer wall must produce heat, which is not possible due to the construction of the wall. In several cases in Falun and Boden the U-values were so low that the insulation would need a thickness of more than one meter, while the insulation thickness in Lund never has to exceed 500 mm. Even during the most favorable conditions, the results still show the difficulty of achieving reasonable insulation thickness, as well as a positive U-value. This is especially true with regards to Boden, but in part also Falun.In conclusion, while it is possible to construct a small house that meet the requirements for the level FEBY Gold in the south of Sweden, it is increasingly challenging the further north you attempt to construct such a building. Even using thicker insulation, the requirements are difficult, if not impossible, to achieve in the north of Sweden. Under current conditions, the wall would need to generate its own heat to meat the heat loss figure demanded by the FEBY Gold standard.

In order to satisfy requirements of the Global Threat Reduction Initiative (GTRI), the 6 MW MIT Research Reactor (MITR-II) is to convert from the current 93%-enr 235U highly-enriched uranium (HEU) fuel to the low-enriched uranium (LEU, <20% 235U) fuel. This reduction in enrichment decreases the neutron flux level due to parasitic absorption by 238U. The neutron flux may be compensated for by increasing the reactor's nominal operating power level to 7.0 MW. Thus a neutronic and thermalhydraulic study was undertaken to evaluate new fuel designs with graded fuel meat thickness and unfinned clad that provide sufficient safety margins for steady-state operation at 7.0 MW. A previously-studied 18-plate LEU fuel design and an identical unfinned fuel design were compared to evaluate the effect of fin removal, demonstrating the need for fuel redesign. A recent feasibility study has shown that a 19-plate, unfinned fuel design with graded fuel meat thicknesses (19B25) provides fuel cycle length and steady-state thermal hydraulic safety margins that meet the design criteria. The objective of this study was to use the RELAP5 MOD3.3 code to confirm the steady-state thermalhydraulic safety margin and to analyze the loss-of-flow (LOF) transient performance of this candidate fuel design. Power distributions obtained for beginning-of-life (BOL), middle-of-life (MOL), and end-of-life (EOL) were analyzed to study the effect of core power distribution and burnup-dependent thermal properties on safety margins. Results show that the MITR-II can safely operate at 7.0 MW with the proposed LEU fuel with an adequate margin (40%) to the onset of nucleate boiling (ONB) -limiting power level. The minimum margin between coolant channel wall and saturation temperatures was at least 22 C in the most limiting channel, in the most limiting core (BOL) at 7.0 MW. The proposed LEU fuel design also performed well during a simulated LOF transient after operation at 7.0 MW, with a peak fuel temperature of 106 C reached in the hot channel, which is well below the U-1OMo blistering temperature of 365*C. During the LOF transient, the maximum clad temperature was 980, meaning that no boiling occurred even during the LOF transient. Bounding analysis to evaluate the effect of an oxide layer and fuel meat thermal conductivity due to fuel burnup estimated that up to a 15 C peak fuel temperature rise can be attributed to increased thermal resistance of oxide layer and fuel thermal conduction reduction. Thus under the most conservative assumption, the estimated peak fuel temperature is 121 C, well under the blistering temperature limit of 365 C. It is concluded that the 19-plate unfinned fuel design with graded fuel meat thickness is a promising candidate for the conversion to LEU fuel and power uprate.

Повний текст джерелаThis thesis deals with the characterization of siliceous (S) and limestone-siliceous (SC) concretes when exposed to high temperatures. The understanding of the degradation of their properties, in advance of the melt front, is the hypothesis that motivates this work since it could bring new avenues to interpret the results of these experiments. Samples that have never been in contact with molten metals/oxides were first studied. Thermo-gravimetry, mercury intrusion porosimetry and complex impedancemetry were used to describe their properties after they were subjected to temperatures up to 1000°C. Thermo-gravimetric analyses allowed the identification of temperature domains in which specific degradation mechanisms are activated. Those of porosimetry showed that porous volumes and typical pore sizes increase significantly with the temperature. It is also demonstrated that at 1000°C, the exchange surface of SC concretes is twice as large as that of Sconcretes. Finally, the high tortuosity obtained by impedancemetry suggests a topology of porous networks of great complexity. In a second part of this thesis, the studied concrete samples were previously in contact with molten metals and/or oxides. They were analysed by X-ray tomography or scanning electron microscopy. No phenomenon of impregnation of the metal/oxide phases could be observed. Signatures of possible phenomena of percolation of these phases by decarbonation mechanisms have however been demonstrated

Повний текст джерелаThis Ph.D. essays a dissolution of the mind-brain problem, and offers a reformulation of the mind-body problem through the study of the idea of epigenesis. We explore three key moments in its philosophical grounding: XVII century´s German Biology, XIX´s Histology and Biology and XX´s Neurology, Philosophy of Mind and Evolutionary Biology. Paralelly, we introduce our epigenetic approach to the mind-body problem: mind is not a substance as defined by the Cartesian tradition, but neither a myth, as eliminativism sees it: it as a dynamical process which emerges from the complex operations maintained both in the organism (conformed by the rich interrelationships between the brain/nervous system and the body), and the ones maintained with the environment (both natural and cultural) by it as a whole. Body and brain intertwine inseparably not only by genetic processes, but also epigenetic ones, through which the mental functions can emerge and end up being operative.

Повний текст джерелаA new additive manufacturing process for metallic parts, based on the arc welding process known as CMT (Cold Metal Transfer), is studied with the objective of building parts with the aluminium alloy Al5Si. A workbench for additive manufacturing based on the 3D printers open-source principle, on which the CMT generator was integrated, was specially developed. The CMT process allows to control the aluminium wire melting and its deposition under the form of droplets on the building surface, forming, after solidification, beads that can be superposed for the parts construction. The process parameters influence on the material transfer and heat transfer during the metal melting and deposition on the build surface, as well as on the geometric characteristics of the deposed beads, in the case of mono-layer deposits, and in the case of multi-layer walls, is studied. Many geometric defects were observed, and their apparition conditions analysed, thanks in particular to the use of a high-speed camera. The understanding of the relations between the process parameters, the melting and heat transfer mechanisms, and the beads geometry, allowed the defects correction by identifying and modifying the process parameters responsible of their apparition. Finally, an on-line control method for the process, based on the analysis of the voltage and current signals produced by the welding generator during the deposition phenomena, making possible the early detection of defects, and then the modification of the process parameters before they are amplified, has been proposed

Los resultados de este primer estudio sugieren que existe una relación entre la capacidad de diferenciar dos estados mentales (el propio y el ajeno), medida por el éxito en la prueba de la falsa creencia y la capacidad de producir notaciones funcionalmente comunicativas a partir de los 4;6 años. Sin embargo, aunque la capacidad de diferenciar estados mentales constituye una condición necesaria para que se puedan producir notaciones funcionales, no parece ser una condición suficiente. Parece que otras habilidades relacionadas con el conocimiento de los sistemas notacionales y con las habilidades pragmáticas de su uso, juegan un papel importante.
En el segundo estudio, el objetivo se centró en la investigación del efecto de los modos de comunicación en los mensajes producidos con la finalidad de comparar la producción y el uso de notaciones y los mensajes orales. Para ello, 270 niñas y niños mexicanos de 3 a 5 años de edad produjeron notaciones y emitieron mensajes bajo 2 condiciones: veracidad y engaño. Los resultados sugieren una mejora en ambos sistemas simbólicos relacionada con la edad, pero un ligero desfase evolutivo entre ambos modos de comunicación. Los niños más pequeños fueron mejores en sus mensajes orales a diferencia de los mayores que supieron adaptar la información de mejor manera en sus notaciones que en sus mensajes orales.
Finalmente, en el último capítulo de la tesis se discuten los resultados de los dos estudios experimentales y se mencionan las principales conclusiones extraídas de este trabajo.
The thesis focuses en the study of the production and use of notations and their relationship with the mental states knowledge in preschooler children. The first part of the thesis is the theoretical framework which suggests that children develop a great deal of knowledge about external representations before they are formally taught to read or write. In the other hand, research on theory of mind suggests the knowledge of mental states by 4 year old children. This knowledge is determinant in their relationships in the way that it will provide them not only the ability to communicate to others but to adapt a notational message in the way that other person could decode it effectively.
The second part of the thesis shows the results of the two experimental studies that were carried out with Mexican children (3-, 4-, 5-, 6- year-olds). In the first study, 240 children passed the false belief task and the notational task. Results showed a relationship between ones and other's mental states and the ability to produce communicative notations at 4;6 years old.
In the second study, 270 children (3-, 4-, 5 year-olds) not only produced a notation but communicated orally a message. Results suggested a developmental trend in both symbolic systems (oral/notational), but oral messages were better in 3 year old children while notations were more functional in 5 year old children.
Finally, in the last chapters of the thesis, we discuss the results and we mention the main conclusions.

Повний текст джерелаMarinating and brining improve shelf-life, tenderness and juiciness of meat and fish. As a supplement massaging or tumbling is often applied to meat pieces before cooking. The main aim of this study was to assess the impacts of the processing conditions on the biochemical and structural changes in the meat tissue; a great part is focused on massaging. In the marinating trials the pH and NaCl content of thin samples of beef Semimembranosus muscle were set at 6.5, 5.4 or 4.3 and at 0,9 or 2 % (w/w), respectively; an ANOVA have shown the effect of these two parameters on the cells and extra cellular space sizes, the oxidation of lipids and proteins and the protein surface hydrophobicity. A brining-massaging simulator built by the laboratory was used to apply controlled successions of deformations (number from 350 to 2500, compression ratio from 10 to 30 %) to Semimembranosus (SM) ou Rectus femoris (RF) pork muscles. Mechanical treatments similar to those existing in industrial tumblers of various diameters were so reproduced. The main conclusions are: (1) massaging clearly increases the NaCl apparent diffusivity, on the one hand, by a modifying the tissue structure (+20%) and, on the other hand, by adding convection to diffusion (+200%); (2) the mechanical treatment promotes by itself an increase in protein solubility, known to affect processed meat quality, from 20 to 50 % in comparison with salted or unsalted reference samples; (3) it also increases moderately protein hydrophobicity; (4) the endomysium degradation, used as an indicator of structural changes, was more pronounced in the muscle periphery than in the middle and all the more marked than massaging was strong and long

Повний текст джерелаThis article comparatively evaluates the thermal comfort in the use of asphalt pavements versus concrete pavements with the addition of diatomite. The variable that will be considered for the study will be reflectance. For the comparison, the ENVI-met software will be used where areas of Lima that use asphalt pavements identified as Heat Islands (UHI) will be used, which will be replaced by concrete pavements with diatomite and thermal comfort will be seen by the PET method through of the aforementioned program. Finally, those results will be compared.

Повний текст джерелаImproving the nutritional quality of cooked meat products needs a better understanding of protein physicochemical changes induced by heating. This study aims to analyse the mechanisms responsible to protein state changes, in the goal to develop a predictive stoichio-kinetic model of effect of composition and temperature on these changes. An experimental model which represent the physicochemical environment of meat tissue (pH and ionic strength) allowed to quantify the specific effect of heating, composition in fibres, in oxidants (iron, hydrogen peroxide and vitamin C) and in antioxidants (enzymes, vitamins and peptides) on oxidations, thermal denaturation (hydrophobicity) and aggregation of proteins. The stoichio-kinetic model is composed of 43 reactions which represent all phenomenon involved in the experimental model : Fenton chemistry, radical attack on amino acids and thermal denaturation. A system of differential equation solver allows to determine the concentration of compounds during heating ; 3 unknown rate constants were adjusted with experimental kinetics. Experimental results show : (1) a synergistic effect of oxidants and heating on protein oxidation, (2) a negligible impact of oxidants on thermal denaturation and aggregation (3) a significant higher sensitivity to oxidation and thermal denaturation of protein from α-white than those from β-red, (4) an important effect of the composition in oxidants and antioxidants on the protein oxidation levels. Stoichio-kinetic model predictions reproduce experimental tendencies. From this base, experimental and stoichio-kinetic models could be progressively complexified to obtain a predictive tool of nutritional quality of meat

Повний текст джерелаThe Chato Murciano pig is an autochthonous pig breed from the Region of Murcia which is in danger of extinction. The objective of this thesis was the study of the quality parameters for the carcass and the meat of the Chato Murciano, and its cross with the Iberian pig, in both indoor and outdoor farming. Two studies were designed for this purpose. The methods used were those necessary to take the following measurements in live animals and carcasses: live weight, hot and cold carcass weight, carcass yields, storage weight losses, morphometric parameters, weight of most valuable meat cuts and dorsal fat thicknesses. In addition, taking the Longissimus lumbar muscle as our reference, we tested for the following meat quality parameters: pH and colour, intramuscular fat percentage, drip losses, cooking losses, shear force, mineral composition and fatty acid profile in muscle and backfat.

Повний текст джерелаMelt loss during regional high-grade metamorphism has important consequences for interpreting the metamorphic evolution of the lower crust and for understanding processes leading to the chemical differentiation of the crust. However, melt loss typically modifies the protolith; making it difficult to reconstruct the conditions of prograde metamorphism and the extent to which melt loss modified the rock composition. The Reynolds Range in central Australia preserves a rare example where a single melt-prone stratigraphic unit can be traced from greenschist to granulite grade conditions. Using this as a natural laboratory, P–T mineral equilibria forward models have been calculated to explore melt loss and melt reintegration where both the protolith and the residuum compositions are preserved. Incremental melt loss modelling from the protolith composition along an isobaric heating path at 5 kbar shows that the residual granulite facies rock composition is consistent with around 18% melt loss from the protolith. Large-scale, one-step melt loss from a closed rock system that had built up 18% melt resulted in a similar residual composition to incremental melt loss. The fertility of the open (incremental) system and the closed system showed the closed system produced 5.4% more melt along a heating path from 700–800 °C. Determination of the concentrations of K–U–Th with increasing metamorphic grade shows that K and U concentrations decreased with increasing metamorphic grade. Conversely, Th concentrations increased, resulting in a slight overall increase in heat production from the protolith to the residuum, despite around 18% volume loss associated with melt extraction. An implication for this is that for melt prone rocks such as metapelites, melt loss during granulite facies metamorphism does not deplete the concentration of heat producing elements in the lower crust as is typically assumed.

Повний текст джерелаHierdie navorsing is gerig op die aanwending van narratiewe pastorale terapie met breadwinners wat werksonsekerheid tydens 'n rasionaliseringsproses ervaar. Die studie is kwalitatief van aard en is gebaseer op narratiewe pastorale gesprekvoerlng esook die proses van meervoudige refleksie waardeur die navorsing gerig en aangepas word. As navorser was ek deelnemer in die proses van verandering waarin veralgemening genegeer is en die rol van persoonlike kennis beklemtoon is. Die terapie is gerig op proaktiewe optrede tydens die rasionaliseringsproses en is ten opsigte van elkeen van die deelnemers aangewend in pasmaakgesprekke waartydens hul unieke behoefles aandag geniet het. Deur die metode van eksternalisering is die invloed van werksonsekerheid op die deelnemers geeksploreer en is hulie aangemoedig om in 'n ander verhouding tot die probleem van werksonsekerheid le staan. Namate die deelnemers tydens hierdie proses belangrike skuiwe op die vlak van identiteit gemaak het, ken hulie die toekoms met nuwe hoop bejeen.
The research was directed at the application of narrative pastoral therapy with breadwinners experiencing job insecurity during a process of rationalisation. This qualitative study was based on narrative pastoral conversations as well as the process of multiple reflection through which the research was directed and adapted. As researcher, I was a participant in the process of change in which generalisations were negated and the role of personal knowledge emphasised. The therapy was directed at proactive action during the rationalisation process and was applied in respect of each of the participants in a customised conversation. The influence of job insecurity on the participants was explored through the method of externalisation and they were encouraged to adopt a new relationship to the problem of job insecurity. In the process, as each participant made important shifts on the level of identity, they wera able to view the future with new hope.

Повний текст джерелаDie voorkoms van aankoopbedrog vereis van die onderneming se bestuur, ondernemingsrisikobestuurder en interne ouditeur om aankoopbedrogrisiko's effektief binne die konteks van die ondernemingsrisikobestuurskonsep aan te spreek. Die doel van die studie is om `n aankoopbedrogrisikobestuursproses daar te stel wat as `n omvattende raamwerk vir die ondernemingsrisikobestuurder en interne ouditeur kan dien om die onderneming se blootstelling aan aankoopbedrogrisiko's so ver as moontlik te beperk. Die studie fokus eerstens op die ontleding van die stappe in die aankoopproses wat as vertrekpunt vir die identifisering van bedrogrisiko's dien. Tweedens word die ondernemingsrisikobestuursmodel in die vorm van `n aankoopbedrogrisikomatriks in die aankoopfunksie toegepas. Die studie dui daarop dat alhoewel aankoopbedrog nie volkome verhoed kan word nie, die voorkoms daarvan wel beperk kan word deur die toepassing van `n omvattende aankoopbedrogrisikobestuursmodel. Aanbevelings vir verdere studies sluit die toepassing van die ondernemingsrisikobestuursmodel op ander funksionele terreine van die onderneming in.
