Texte intégralNaphthenic acids comprise a complex mixture of carboxylic acids that are present in petroleum. They are directly responsible for the oil acidity and its corrosiveness in liquid phase during the refining process. Such compounds are also presents in the derivatives, causing several problems to product quality. A possible way of removing these acids from those oil fractions is using the adsorption process in porous solids. Nevertheless, results presented so far show that ion exchange resins would be the best adsorbent for these acids, which could make this process very expensive. In this work, two commercial adsorbents (clay and activated alumina) were characterized by several physical-chemistry techniques and evaluated concerning their capacity of removing naphthenic acids from average and heavy fractions of crude oil. For comparison the behavior of commercial naphthenic acids in synthetic commercial samples prepared with mineral oil was also evaluated. In addition, the carbon steel corrosiveness in the studied systems was verified. Clay adsorbent presented better affinity with the acids, showing a greater capacity and a faster kinetics than alumina for synthetic oils. However, because of the higher competition with the other components present in real oils for the adsorption sites, a loss of efficiency for these samples was observed. In that case, alumina showed better results. Although both adsorbents have showed good capacity of removal of acids, the ion exchange resin still presented the best results for real samples. At the conditions of this study, the steel corrosiveness in the synthetic oils, as well as the data obtained for two of the real ones, was not significant, and only one of the real samples (Oil 1) corroded the carbon steel coupon. However, the naphthenic acid removal was able to reduce the corrosiveness in this medium up to 99%

Texte intégralThis thesis explored the potential of clay work and its symbolic representations as a means to facilitate the integration and individuation of the self in psychotherapy, using a Jungian theoretical framework. A case study methodology was used, to explore a long standing pattern of environmental failure and trauma in a 16 year old female. The Edward's clay work method was utilized to guide the use of the clay work and the discussion and exploration thereof. Central to the study was the importance of a search for meaning given to each clay piece, which was achieved through a dialectical interaction and mutual exploration between therapist and client.

Texte intégralENGLISH ABSTRACT: For decades black South Africans suffered under apartheid, being excluded from active participation in the South African economy. Following the first democratic election in 1994, which was won by the African National Congress, the new government immediately made clear its intentions to transform the economy by including all the South Africans citizens. In 2004 the government promulgated the Broad-Based Black Economic Empowerment Act (BB-BEE), which aimed to redress the wrongs of the past and to realise the country's full economic potential whilst assisting the black majority to become part of the economic mainstream. The BB-BEE act focused primarily on the upliftment and empowerment of historically disadvantaged people, particularly black people, women, the youth and the disabled and on those living in rural communities; it aims to include these people in the management and ownership structures of South African companies. The clay brick industry, one of the oldest industries in the world, had been severely affected by the introduction of the legislation, as 75% of businesses were predominantly family owned, and 69.39% of them are predominantly white owned. The primary objective of this research assignment was to investigate the impact of Broad-Based Black Economic Empowerment (BB-BEE) on the South African clay brick industry and to make recommendations to the various stakeholders regarding the management of the introduction of BB-BEE into the industry. The methodology followed a survey approach by using specific indicators to ascertain what the perceptions and experiences of the business owners were, regarding the implementation of BB-BEE in the industry. The study found that the business owners were concerned about losing control of their businesses, that there is very little support from government for businesses entering into BB-BEE deals and that it is difficult to find the “right” empowerment partner which “fits” the culture and management style of the business. The study concluded that much uncertainty, fear and anxiety exists amongst business owners regarding the introduction of BB-BEE. The study also makes practical recommendations to the various stakeholders who may assist with facilitating the introduction of BB-BEE in the industry.

Nos sumergimos en el ámbito de las imágenes desde una vertiente estética pero, a la vez, damos prioridad a una valoración estratégica y táctica con la firme voluntad de medir el impacto que éstas tienen a nivel comunicacional. Aprendemos a leer correctamente las imágenes y las etiquetamos a partir de ciertos rasgos que las caracterizan y las significan: los atributos. Los atributos se convierten en una herramienta fundamental para los creativos y para las marcas ya que les permite alinearse y satisfacer, de manera adecuada, los gustos, los hábitos, los deseos y las preferencias de los consumidores de la sociedad contemporánea. La activación correcta de cada uno de los siete atributos analizados, en determinadas casuísticas concretas, permite impulsar y estimular las dinámicas del mercado, otorgando relevancia y diferenciación a las propuestas ofertadas y mejorando sus resultados en términos de posicionamiento y amplificación.

Visual language shapes our reality and we must be able to interpret it if we want to make sense, control and engage with our market environment. We will delve in the world of images from an aesthetic perspective and, at the same time, we give priority to a strategic and tactical evaluation with a firm will to measure the impact they have on a communication level. We learn to correctly read images and we tag them based on certain aspects that characterise and explain then: attributes. Attributes turn into a fundamental tool for creatives and brand allowing them to align and satisfy, in an adequate manner, tastes, habits, wishes and preferences of today’s consumers. Activating each of the seven analysed attributes correctly, in certain designated cases, impulses and stimulates market’s dynamics, giving relevance and differentiation to proposals and improving its results in terms of positioning and amplification.

Texte intégralThis research based on an inductive approach, studies what the students became after having studied in a high school where different educational methods and an official school project inspired by the new education emphasize the ambition to train responsible and autonomous young students, open-minded as well as creative, who are able to adapt, evolve and work in a team. The methodological device of data collection consists of 42 accounts made by former students of this particular school who left the institution between 1990 and 2005, but also of secondary analyses of existing surveys, statistics produced by the school institution and the follow-up of 450 former students on social networks since 2008. The results show how these students built their identity thanks to a particular school experience and how according to them, their school years changed who they are today. They also show that what was decisive in the long run for their own personal success, their social and professional integration, happened outside their class, thanks to relationships and autonomous learning process between peers, but also between adults and themselves, or with the building of lasting social network and in the development of psychosocial skills where the collective dimension is central. This study also demonstrates that this school isn't aside the world but on the contrary that their words tell about what the future students will be

O gênero Cuphea, popularmente conhecido no Brasil por “sete-sangrias”, tem seu uso medicinal reconhecido devido aos efeitos diurético, hipotensor e cardioprotetor. No sul do Brasil, em região característica do bioma Pampa, foi encontrada a espécie Cuphea glutinosa Cham. & Schltdl. Embora o uso popular, esta espécie é pouco descrita na literatura. O presente trabalho tem como objetivos o estudo da composição química dos extratos de C. glutinosa e a avaliação das atividades antifúngica e anti-hipertensiva. O material vegetal foi coletado na cidade de Uruguaiana (RS, Brasil), identificado e depositado em herbário. Após secagem e trituração do material vegetal, foram obtidos os extratos hidroetanólicos através de maceração exaustiva com etanol 40% (v/v) para folhas e etanol 70% (v/v) para raízes. Para a infusão, utilizou-se água a 80oC. As análises cromatográficas foram realizadas em equipamento cromatógrafo a líquido Prominence Shimadzu, em técnica por CLAE e CLUE. Utilizou-se sistema de fase reversa, eluição por gradiente com fase móvel composta por acetonitrila:metanol (4:1) e ácido fórmico 0,1% pH 3,0, coluna C18 analítica e fast, e detecção por UV-DAD e ESI-MS. Os teores de polifenóis totais e de flavonóides foram determinados por método colorimétrico, seguindo metodologia padronizada. A atividade antifúngica in vitro foi realizada utilizando o método de microdiluição em caldo, determinando-se a CIM, in-vitro, contra diferentes isolados clínicos. Para avaliação do potencial anti-hipertensivo in vivo, foram realizadas medições da pressão sanguínea pelo método de monitoramento hemodinâmico invasivo, através da inserção de cateter na artéria carótida. Os resultados de teor de fenólicos totais indicaram predominância destes componentes em extratos obtidos de folhas e por maceração, conforme os valores obtidos: 1,8501 mg EAG/mL (folhas) e 0,8467 mg EAG/mL (raízes) para infusão, e 3,7284 mgEAG/mL (folhas) e 2,6266 mg EAG/mL (raízes) para maceração. Quanto ao teor de flavonóides, os resultados quantitativos foram: 7,0959 mg/g (folhas) e 0,5664 mg/g (raízes) para a infusão, e 7,9511 mg/g (folhas) e 0,5994 mg/g (raízes) para maceração. Na análise cromatográfica, os extratos obtidos das folhas de C. glutinosa apresentaram picos cromatográficos bem separados, em perfil reprodutível. Na determinação por CLUE-MS, os dados de íon molecular e fragmentos de massa indicaram a composição predominante em flavonóides, sugerindo-se os componentes quercetina-3-O-glicosídeo, quercetina-3- arabinosídeo, quercetina-3-glicuronídeo, isoramnetina e quercetina-5-O-β-glicopiranosídeo. Para o potencial antifúngico, os extratos das folhas e raízes apresentaram atividade in vitro contra Candida parapsilosis, Candida tropicalis e Trichosporon asahii, com CIM variando na faixa de 1,9-62,5 μg/mL. Nos testes hemodinâmicos realizados, os extratos das folhas não apresentaram efeito significativo sobre a pressão arterial. A identificação dos componentes em C. glutinosa, derivados de quercetina, torna promissora novas investigações a fim de aprofundar o conhecimento a respeito desta espécie, em especial na busca de respostas para a relatada ação anti-hipertensiva.
The Cuphea genus, popularly known in Brazil as "sete-sangrias", is used traditionally due the diuretic, hypotensive and cardioprotective effects. In southern Brazil, in characteristic region of Pampa biome, it was found the species Cuphea glutinosa Cham. & Schltdl. Although used popularly, this species is few reported in the literature. The present work aimed to study the chemical composition of extracts from C. glutinosa and to evaluate the antifungal and anti -hypertensive activities. The plant material was collected in the city of Uruguaiana (RS, Brazil), identified and deposited in a herbarium. After dryness and milling, the hydroethanolic extracts were obtained through exhaustive maceration using ethanol 40% (v/v) for leaves and ethanol 70% (v/v) for roots. The infusions were prepared using water at 80 °C. The chromatographic analyses were performed in liquid chromatography Prominence Shimadzu, for HPLC and UPLC assays. The method was conducted using reverse phase system, gradient elution with mobile phase composed by acetonitrile:methanol (4:1) and formic acid 0.1% pH 3.0, C18 analytical and fast column, and detection by UV-DAD and MS. The polyphenols and flavonoids contents were determined by colorimetric method. The in vitro antifungal activity was conducted by using the broth microdilution method, determining the MIC against different clinical isolates. For evaluation of in vivo anti-hypertensive potential, the blood pressure was measured by the method of invasive hemodynamic monitoring, through of insertion the catheter into the carotid artery. The results of phenolic content indicated the high concentration of these compounds in leaves extracts obtained by maceration: 1.8501 mgEAG/mL (leaves) and 0.8467 mgEAG/mL (roots) for infusion, and 3.7284 mgEAG/mL (leaves) and 2.6266 mgEAG/mL (roots) for maceration. For flavonoids, the contents were: 7.0959 mg/g (leaves) and 0.5664 mg/g (roots) for infusion, and 7.9511 mg/g (leaves) and 0.5994mg/g (roots) for maceration. In the chromatographic analyses, the leaf extracts from C. glutinosa presented chromatographic peaks well separated and reproducible. In the determination by UPLC-MS, the molecular ion and mass fragments indicated the predominant composition in flavonoids, suggesting the compounds quercetin-3- O-glucoside, quercetin-3-arabinoside, quercetin-3-glucuronide, isorhamnetin and quercetin-5- O-β-glucopiranoside. For the antifungal potential, the leaf and roots extracts presented activity against Candida parapsilosis, Candida tropicalis e Trichosporon asahii, with MIC values ranging 1,9-62,5 μg/mL. In the hemodynamic tests performed, the leaves extracts did not present significant effect in the arterial pressure, although a tendency in pressure reduction could be observed. The identification of quercetin derivatives in C. glutinosa becomes promisor further investigations about this species, mainly in respect to the anti-hypertensive action.

Texte intégralGodrant, Aurélie. « The role of superoxide in iron acquisition by marine phytoplankton ». Brest, 2009. http://www.theses.fr/2009BRES2061.
Texte intégralIt is hypothesised that, under iron limitation, phytoplankton cells develop biochemical mechanisms to increase their iron uptake efficiency with one of these mechanisms involving the production of superoxide in the extracellular environment that increases the bioavailability of iron in seawater by reducing Fe(III) to the more soluble Fe(II). The main objectives of this work were 1) to develop an appropriate method to detect extracellular production of superoxide by marine phytoplankton, and 2) to examine the relationship between extracellular production of superoxide and iron acquisition by Trichodesmium erythraeum. A method to measure superoxyde production is described using red-CLA and MCLA probes, yielding considerable improvement for analysis compared to other available methods. Extracellular superoxide production and iron uptake rates were measured simultaneously on iron replete and iron deplete Trichodesmium erythraeum IMS 101 laboratory cultures : iron starvation leads to a 2. 9-fold increase in superoxide production rate and 10-fold decrease in the iron uptake rate (except when a reducing compound was added) compared to iron replete cultures. Extracellular superoxide production shows a pronounced circadian rythm in iron deplete cultures, but less so in iron replete cultures. Overall, no direct impact of extracellular superoxide production by Trichodesmium is observed, but both processes are shown to be related. Both iron deplete and iron replete cultures demonstrate greater ability to uptake iron bound to weaker iron-binding ligands such as citrate. Application of the method to field studies in the Great Barrier Reef lagoon showed an accumulation of biologically significant concentrations of reduced trace metals including Fe(II) when the concentration of superoxide was lower than 1 nM. When the concentration of superoxide was higher than 1 nM, most of the reduced species were oxidised resulting in high rates of hudrogen peroxide production rates, consistent with laboratory studies. Overall, this thesis permitted the development of a method to detect superoxide production rates by marine phytoplankton cells that could be used routinely in field studies. The observations are in accord with the conclusion that fit the ongoing hypothesis that the extablished Fe' uptake model for phytoplankton would be strongly influenced by such organisms that are able to modify the redox equilibrium of the solution at their cells surface

This study explores the mechanism of the active lateral force in undrained clay when there is a spatial variability in the clay. It is shown that the effect of such spatial variability cannot be fully explained by the pure spatial averaging over a prescribed area or line; the tendency to seek the weak path for the critical slip curve is also important. Ignoring this important mechanism is risky, rendering the active lateral force estimate smaller than the actual value. Furthermore, pure spatial averaging cannot capture the phenomenon of the critical scale of fluctuation (critical SOF). However, it is found that the phenomenon of the critical SOF is connected to the nature of the spatial averages. The line averaging effect is significantly weaker than the area averaging effect, so the tendency for the critical slip curve to seek for a favorable location is stronger. Hence, the phenomenon of the critical SOF is more pronounced. It implies that if a strong pure spatial averaging is mistaken, the critical SOF can probably be ignored. This makes pure spatial averaging methods unconservative. Pure spatial averaging cannot capture this phenomenon of the critical SOF, because it cannot quantify the tendency of seeking the weak path. Therefore, the mechanism of seeking the weak path is explored in this study, and a probability distribution model for the active lateral force is proposed to characterize this sophisticated mechanism. Furthermore, a simplified procedure based on the distribution model is proposed to simulate the active lateral force samples without the use of the random finite element method or limit equilibrium method.

We use DOPO、4-hydroxyacetophenone、4-hydroxybenzaldehyde and phenol novolac to synthesize phosphinated epoxy curing agents. The resulting thermosets achieved high glass transition temperature. However, in order to satisfy the needs in electrical industry, we further introduced active ester linkages into them, and then cured with DGEBA and HP7200. The thermal properties, dielectric properties, flammability, and moisture absorption were investigated. The active ester-containing thermosets achieved great thermal properties and thermal stability. From data of dielectric properties, the dielectric constants and dissipation factors were decreased because of the modification with active ester linkages. The moisture absorption also trended to decreasing. Finally, the phosphinated thermosets achieved UL-94 V-0 grade because of the flame-retardancy of DOPO.

With the escalating demands for optical communication network system, the need for broadband gain medium in optical communication has increased. Among them, Cr4+:YAG crystal has shown an exceptionally successful broadband amplified spontaneous emission (ASE) light source that fully cover 1.2-1.6 μm range (3-dB bandwidth up to 265 nm). More recently, we demonstrated the realization of a waveguiding, low-loss, and low-threshold Cr4+:YAG double-clad crystal fiber (DCF) based ultra-broadband ASE light source, optical amplifier, and laser grown by the co-drawing laser-heated pedestal growth technique. These results demonstrate the potential of the Cr4+:YAG DCF for the replacement of the erbium doped fiber in future optical communications. To further improve the efficiency of Cr4+:YAG DCF based active devices, here we show the difference in thermal expansion coefficients between a YAG core and an inner cladding creates a significant localized strain field by near-field scanning optical microscope (NSOM), which can result in optical confinement and provide the possibility to simultaneously alter the Cr3+ and Cr4+ fluorescence lifetime with varied core dimensions. The results indicate that There exists a nearly zero strain across the entire core with a diameter of ~20 μm, which is beneficial the higher Cr4+ fluorescence lifetime (+6.43%) and emission cross section (+19.17%) as compared with 11-μm core. In addition, we have successfully investigated the near-field modal characteristics of Cr4+:YAG DCF laser and ASE by NSOM. The results demonstrate that the Cr4+:YAG DCF laser produced nearly a single-mode (LP01) output with diffraction-limited beam quality of M2 ~1.1; for ASE, the modal weighting of LP01 decreases from 26% to 15% as the number of modes increases from 4 to 7. The results offer a guideline not only for further fabricating Cr4+:YAG DCF tunable lasers, but for efficiently coupling a broadband ASE light source into a single-mode fiber.

Sensory integration dysfunction problems were rarely mentioned in the past because people last generation often grew up playing. In the early childhood development, the tactual sensation is the most basic and influential system; at the age of three, the tactual interest moves from the body to hands, so that the children are excited by colorful vision and try to understand the surrounding people, things and environment by touching with hands. Among all materials, clay is easy to shape and may better stimulate the body''s sensory development due to the unique plasticity touch. The purpose of the study is to design a creative thinking teaching model for preschool children aged four to six with children clay courses and to facilitate the development of children''s tactual sensation through discussion and analysis after teaching activities. The study carried out two teaching activities for an action research. Before that, it discussed literature of theories of sensory integration, children cognition development, children painting development and creative thinking education and compiled cognition and children painting development theories suggested by Piaget, Lowenfeld and Eisner, according to which it designed a set of clay teaching model and performed teaching activities based on the creative thinking. The first teaching activity, research tools and data collecting methods were reviewed and inspected according to the principles of creativity-oriented teaching, for the amendment reference for the second teaching activity. Tests were done with a "scale of sensory integration capabilities" before and after implementing the second teaching activity; after the teaching activity is over, the measurement is used as the main basis for the discussion about tactile and other sensory development, supplemented by teachers'' journals, lesson learning sheets, recordings, videos, students'' works, etc. After the teaching activities of the study, the test result and analysis showed that: 80% of the students progressed in the result of sensory action sequence on both sides, while 13% regressed and 7% remained the same; 67% of the students progressed in the sensory adaptation result, while 33% regressed and 0% remained the same; and 46% of the students progressed in the sensory searching result, while 47% regressed and 7% remained the same. Based on the said data and the support of other research tools, the researchers discovered that more than 50% of the data confirmed that the clay material may facilitate the development of children’s'' tactual sensation after four weeks of the course.

Abstract This research was applicable to children with developmental delays. The influence of clay-teaching on such children and the changed on their concentration spans. Method used: Action research Two developmental delayed individuals together with four ordinary students were placed in a 3 months program. Thereafter subjects were placed in the same environment to be observed and educated. The Program was conducted twice a week, 15~20 minutes per session and the program was only 3 months. Thereafter, children were placed in the same class environment for the observations and records. The research records the thought process notes (hand notes), discussions, interviews and concentration capability assessments. The raw data were analyzed and decrypted. Information revealed are as follows: (一) 6 steps to put clay-teaching in practice: 1. finding volunteers who are willing to participate (subject) 2. class schedule arrangement 3. target setting 4. design unit topics 5. work allotment 6. lesson plan and assessment preparation The course comes in various forms, in total there are 24 topics. Recognition, appreciation and creative abilities are the main pillars of the course.(二)Art and special education can be collaborated. Clay teaching in the special class can bring out the abilities of individuals such as combination recognition, appreciation and creativity. Simultaneously, it could also be upgraded into a systematic art course design.(三)Two subjects has benefited from the course by increasing their attention- span from below 3 minutes to over 15 minutes, clearly there is an improvement. (四)After the implementation of the clay teaching program, subjects has improved on issues such as delicate actions, oral presentation, social interactive behavior, acknowledgement, understanding and the ability to put things in order. Finally, the information concluded above may serve as a reference for individuals or departments concerned.

In 2008, the Ministry of Education in Taiwan, R.O.C. reformed the special education expecting to promote the inclusive education in the framework of the Grade1-9 Curriculum and the principles of Special Education New Curriculum Guideline. Furthermore, the Ministry of Education carrying out the Aesthetic Education Plan recently, the researchers was induced to design a suitable visual arts curriculum for children with mild mental retardation by reference to the Arts and Humanities Area of the Grade 1-9 Curriculum Guidelines. Consequently, this study aims to investigate the feasibility and the specifications of implementing and designing a multi-material clay arts curriculum for the children with mild mental retardation; by multi-sensory method, to design a suitable visual art curriculum used clay as the main teaching mediums with other materials for the children, then after excuting the courses, to investigate the learning effectiveness of children with mild mental retardation. In this study, the researcher used the action research method to record and observe the courses by videos, records of classroom observations, individualized education program and interviewing experts and parents to get qualitative analysis. The conclusions of this research included: (1) In accordance with the Grade 1-9 Curriculum Guidelines combined with special education teaching strategies and principles to design the clay art courses for mild mental retardation children is feasible and has the effectiveness of teaching; (2) Multi-sensory teaching method is adapted for children with mild mental retardation which can effectively enhance their learning; (3) The study courses really can effectively upgrade the performance of children with mild mental retardation in color perceptions, such as primary colours and lightness; (4) The use of aid tools-measuring spoons can effectively enhance the quality of clay techniques and works for children with mild mental retardation .

With curricular development as the center of active research, this research aims to integrate clay creation into life curriculum, probing the effect on the creation of elementary school students. The procedure is conducted on 18 elementary school students in Keelung City in 5 weeks, 3 periods a week, 40 minutes a period, altogether 15 periods. This research applies pretest-posttest design to testify the creational performance of the subjects with quantified results. Taking Torrance Tests of Creative Thinking as a tool, this research analyzes the test results with t-test, which were taken before and after the courses with version A and version B of Torrance Tests of Creative Thinking. With a view to understanding the creational performances of subjects after the implementation of the course, learning feedback sheet, analysis of students' work and teachers' logs are inspected, which would offer multi-dimensional response and verification. The conclusion includes the following three. First of all, clay creation course suits elementary school students' life curriculum as it is easier and multi-dimensional for junior students to learn. Besides, clay creation course shows great effect on the creation of the second-graders in elementary school. Based on Torrance Tests of Creative Thinking, students make good progress on the indexes of “Fluency”, “Originality”, “Abstractness of Title”, “Elaboration”, and “Creativity index”. Thirdly, according to the creation analysis of students' works, clay creation course does help improve students' creation. This research aims to be a reference for the future studies and teachers who might integrate clay creation course into the elementary school curriculum.

Conjugated linoleic acid (CLA) is a compound that contains eighteen carbons and unsaturated fatty acids with two double bonds. CLA has been shown to enhance the fatty acid oxidation and reduce the body fat in animal studies. However, there were adverse effects on glucose uptake were found in obese human studies. Little study was found regarding to whether short term CLA administration is expected to influence glucose homeostasis and reducing insulin action in health humans. Therefore, the present study was to examined that effect of eight weeks oral CLA supplementation on whole body glucose and insulin response in health human study. Twelve male subjects (21.58 ± 0.53 yrs) completed eight weeks CLA supplementation (4.0 g per day). Before (baseline) and at the 4th week and the 8th week after CLA supplementation, all subject accepted OGTT test (oral glucose tolerance test, OGTT) and calculated AUC of glucose and insulin. Simultaneously, ISI (insulin sensitivity index) was calculated for represented the insulin action. No significant change in body composition was found in the present study. However, the AUC in glucose and insulin level after OGTT test were higher compared to baseline. In addition, ISI value was decreased significantly from 4th week to 8th week CLA supplementation compared to baseline. The results in this study implied that there was no change in body composition after eight weeks CLA supplementation. In addition, the CLA supplementation influenced glucose homeostasis and reduced insulin action in health humans. Keywords: CLA, OGTT, insulin sensitivity

The objectives of this study were: 
To review and understand flow and transport processes in unsaturated zones. In this study, particular emphasis is placed on understanding mechanisms that cause non-uniform (preferential) flow for two casestudies, namely the Cape Flats sandy environment and the Mpumalanga Highveld fractured rock environment. 
To evaluate the adequacy of models, in particular MACRO 5.0, in simulating flow and transport in the vadose zone, by making use of two case study sites (Cape Flats and Mpumalanga Highveld). Of particular importance is the evaluation of transfer coefficients to represent fluid and solute exchange between macropores and matrix. 
To run a sensitivity analysis with MACRO 5.0 in order determine which input model parameters are the most relevant in describing the effects of preferential flow in water and solute transport.
