AFRIKAANS: Die vraag onstaan of insette by aartappelproduksie deurentyds ekonomies optimaal gebruik word. Hierdie vraag word al hoe meer deur produsente gevra, veral waar die prysknyptang al hoe sterker gevoel word. Uit ‘n opbrengs oogpunt was stikstof nog altyd ‘n baie belangrike inset. Verliese aan opbrengste kan egter baie groot wees as stikstof ondoelmatig bespaar word. Om optimum stikstoftoedienings te kwantifiseer bly problematies. Die stikstofinhoud van die grond kan gemeet word, maar in hierdie studie is bewys dat die inligting uit hierdie ontledings dikwels misleidend en kan sinvolle aanbevelings nie altyd daarvolgens gemaak word nie. Aan die ander kant, kan die aartappelplant as indikator gebruik word. Die afgelope dertig jaar was baie aandag aan petioolsapekstraksie reg oor die wéreld gegee. Meeste navorsers versap die petiool en gebruik duur laboratorium toerusting om die NO3--konsentrasie te bepaal en maak dan daaruit afleidings. Met hedendaagse tegnologiese ontwikkelings, het vinniger ontledingstegnieke beskikbaar geword. Die Reflectoquant (Merck) is ‘n draagbare instrument wat gebruik word om die NO3--konsentrasie in die aartappelpetioolsap direk te meet. Met kalibrasie-proewe wat deur Omnia gedoen was, is ‘n optimale NO3--konsentrasie reeks (OPTI-reeks) opgestel waarmee stikstof bo-bemestings geskeduleer kon word. Die bepaalde OPTI-reeks is oor twee persele getoets. Die twee persele het verskil in grond tekstuur en ligging. Die Delmas perseel het ‘n hoër klei-inhoud gehad as die Bronkhorstspruit perseel. By die Bronkhorstspruit perseel het verskille tussen die behandelings gouer na vore gekom. Die persele wat laer vlakke van stikstof bemes was, en eerste stikstof bemes is het die laagste NO3--konsentrasie lesings gehad. By die Delmas perseel het hierdie tendens nie herhaal nie. In van die lesingtye het die laer stikstofbemestingsbehandelings hoër ontledings gehad. NO3--konsentrasie lesings, soos vermeld is in die meeste literatuur, het afgeneem oor tyd en gedui op ‘n verdunnings-effek van NO3--konsentrasie in die aartappelplant. Die verdunnings-effek kan toegeskryf word aan die fisiese verdunning van NO3- oor ‘n groter wordende plante, knolle en die gebruik van die NO3- in plantmetaboliese aktiwiteite. Opbrengste en bakkwaliteit van die onderskeie behandelings, was nie verlaag deur die OPTI-reeks te gebruik nie. As in ag geneem word dat ten minste, 45 kg ha-1 stikstof bespaar kon word deur gebruik te maak van die OPTI-reeks, is die metode ‘n baie kragtige ontledingstegniek om stikstof doelmatig te skeduleer. Stikstof sal nie die beperkende faktor in produksie wees, indien hierdie tegniek te gebruik word nie. ENGLISH: The question arises whether inputs are used optimally in an economical way for potato production. This is something that is asked more and more by producers. Nitrogen plays a dominating role in determining yield. Yield losses will be considerable if nitrogen is saved in an unnecessary way. To quantify optimum nitrogen applications can be difficult. Determining the nitrogen content of the soil can be one option, but as was shown in this thesis, this method can lead to incorrect nitrogen applications. The potato plant itself can be used as an indicator for nitrogen applications. For the past thirty years, a lot of emphasis has been placed on petiole sap analyses. Petioles were liquified and then expensive laboratory equipment were used to determine the NO3--concentration, whereafter the recommendations for nitrogen application were made. Analyses are made easier today with modern technological methods and equipment. Direct measurement of the NO3--concentrations in the potato petiole are possible by using the Reflectoquant (of Merck). Omnia Fertilizers conducted many experiments to determine an optimal NO3--concentration range (OPTI-range) to schedule nitrogen applications. In this study the OPTI-range was tested at two sites. The two sites differed in soil texture and district. The Delmas site has a higher clay percentage than the Bronkhorstpruit site. Quicker reactions on the treatments were found at the Bronkhorstspruit site. The plots that received lower nitrogen treatments, were fertilized first and had the lowest NO3--concentrations in the sap. This tendency was not replicated at the Delmas site. The lower nitrogen treatment plots sometimes had higher NO3--concentrations than the higher nitrogen treatments. NO3--concentration readings, as mentioned in most literature, declined over time and is explained by the diluting effect of nitrates in the plant. Not only is there an increase in the potato plants above ground growth, but tuber growth also constitute a big proportion of the biomass at the end of the growth period. Nitrogen is used in all these processes, which contribute to the diluting effect. Yield and tuber quality were not lowered by applying the OPTI-range. The OPTI-range is a good method to manage nitrogen requirements of the potato plant. At least 45 kg ha-1 nitrogen could be saved by using the OPTI-range. Therefore this is a powerful method to determine nitrogen scheduling. Nitrogen will not be the limiting factor in potato fertilization if the OPTI-range is used. / Dissertation (MSc(Agric))--University of Pretoria, 2010. / Plant Production and Soil Science / unrestricted

Die afskaffing van lyfstraf in Suid-Afrikaanse skole het tot groter dissipline probleme onder leerders gelei. Onderwysers raak toenemend gefrustreerd aangesien min praktiese oplossings vir hierdie probleem bestaan. Hierdie studie bestudeer die rol wat agtergrondmusiek in die klaskamer kan speel om die leerling se konsentrasievermoë te verhoog, sy gedrag positief te verander en so die algehele dissipline in die klassituasie te verbeter. Agtergrondmusiek vorm deel van elke kind se leefwêreld aangesien moderne tegnologie dit maklik maak om musiek oral en altyd te luister. Leerders luister ’n groot gedeelte van elke dag na musiek, ook terwyl hulle huiswerk doen. Daarom was dit nodig om die tipe agtergrondmusiek te vind wat voordelig kan wees vir die leerder in ’n klassituasie. In hierdie studie is van praktiese aksienavorsing binne ‘n kwalitatiewe navorsingsontwerp gebruik om die ervarings van leerders tydens die aanwending van verskillende tipes agtergrondmusiek in die klaskamer te bepaal. Uit die verband tussen die leerders se gedragspatrone en waarnemings nadat klassieke instrumentale musiek in die klaskamer gespeel is, kan bevind word dat hierdie tipe agtergrondmusiek as potensiële tegniek gebruik kan word om dissipline in die klassituasie te verbeter. The abolition of corporal punishment in South African schools led to greater discipline problems among students. Teachers are becoming increasingly frustrated as few practical solutions to this problem exist. This study examines the role that background music in the classroom can play in the child's ability to concentrate, increasing his positive behavior and so the improvement of discipline in the classroom. Background music is part of every child's world as modern technology makes listening to music part of everyday living. Learners listen to a large portion of music every day, even while they are doing homework. Therefore it was necessary to study the influence of background music as to what extend it can benefit the student in the classroom. This study used practical action research within a qualitative research design. From the relationship between the learner's behaviour and observations after classical instrumental music was played in the classroom, this type of background music can be used as a potential technique to improve discipline in the classroom. / Dissertation (MMus)--University of Pretoria, 2014. / am2014 / Music / unrestricted

Ozone, being an unstable molecule, is believed to be one of the strongest oxidant agents known to man. Rapid growth in the application of ozone — both as disinfectant and as form of alternative medicine — led to questions about the effects of uncontrolled ozone exposure and inhalation, whether intentional or unintentional, on the human body. This study specifically focussed on examining, identifying and substantiating the respiratory effect of acute exposure (10 min or less) to considerably higher ozone concentrations than reported on before (19.5 ± 0.5 ppm). Respiratory tissue of rodents (Duncan–Hartley guinea pigs of both sexes and Male Wistar rats) was subjected to ozone by utilising three distinctly diverse models of ozone introduction: (a) in vitro exposure, (b) in vivo exposure, and (c) ex vivo by employing an isolated lung perfusion model which allows for real–time, breath–by–breath data acquisition of ozone’s effect on respiratory mechanics. The effect of ozone on the isolated trachea in the presence of various drugs with well–known effects, including methacholine, isoproterenol and ascorbic acid was also examined. The results found in this study identified two direct effects on the isolated trachea due to ozone exposure: (1) a definite contraction of the isolated trachea immediately after exposure to ozone, and (2) a clearly visible and significant hyper responsiveness of the isolated trachea to irritants, e.g. methacholine. Although ozone has a negative effect on the trachea, it was concluded that ozone has no adverse effect on muscarinic acetylcholine receptors. An apparent EC50 value of ozone on the trachea was established by two different methods as (2.77 ± 0.02) x 10–3 M and (2.10 ± 0.03) x 10–3 M, respectively. Ozone furthermore displayed an attenuation of the beneficial pharmacological response of –sympathomimetic drugs (i.e. isoproterenol), while isoproterenol itself has a relaxing effect on the ozone–induced contraction of the isolated trachea. Indomethacin pre–treatment of isolated tracheal tissue significantly (77%) reduced the ozone–induced contraction of tracheal smooth muscle, suggesting that COXproducts of arachidonic acid play a prominent role in the development of pulmonary function decrements consequent to acute high–dose ozone exposure. Ascorbic acid exhibited a meaningful prophylactic effect on ozone–induced contraction of both isolated tracheal tissue and in the isolated lung perfusion model, emphasising the major role antioxidants play in both the epithelium lining fluid (ELF) of the respiratory system and in plasma throughout the body in protecting against the destructive effects of ozone. Surprisingly, pre–treatment with ascorbic acid did not prevent hyper responsiveness of isolated tracheal preparations to methacholine after a 10 min ozone (19.5 ± 0.5 ppm) exposure. In the lung perfusion model, the presence of ascorbic acid in the perfusion medium did, however, significantly reduce the magnitude and rate of decline in lung compliance after ozone exposure (46% decline with ascorbic acid versus 96% in the control study without ascorbic acid). Examination of a lung perfusion model exposed to ozone (19.5 ± 0.5 ppm O3; 5 seconds) presented a significant decline in lung compliance (95.6% within 2 min), tidal volume (70%) and maximum inspiratory flow (71.2%), with an ensuing reduction in lung elasticity and severely hampered breathing pattern. Microscopic examination after acute high–dose inhalation studies did not display any significant cellular damage, oedema or inflammation after acute high–dose ozone exposure. This suggests that significant cellular injury and inflammation is possibly not the causative factor of early breathing difficulty experienced after acute high–dose ozone inhalation, as these symptoms and particularly the result of inflammatory precursors, is believed to probably only set in at a later stage. Although the potential advantages of ozone in certain fields of medicine are not disputed, ozone, depending on its concentration and cumulative dose, can be either therapeutic or toxic. Observations in this study emphasised that even short bursts of high–dose ozone inhalation have deleterious effects on respiratory health and care should be taken not to jump to conclusions regarding ozone’s medical application without relevant scientific evidence. It must be stressed that high–dose inhalation of ozone should be avoided at all cost – especially by those with existing airway diseases. / Thesis (Ph.D. (Pharmacology))--North-West University, Potchefstroom Campus, 2011.

Abstracts in Afrikaans and English / Inklusiewe onderrig ondersteun die insluiting van alle leerders met verskillende behoeftes en vaardighede in klaskamers, wat baie keer te groot, of te verskillend vir doeltreffende onderrig is. Beweging as deel van ‘n vroeë leerervaring is noodsaaklik vir optimale neurale ontwikkeling. Dit beïnvloed organisasie en stimuleer die spesifieke neurologiese sisteme nodig vir optimale funksionering en ontwikkeling van die brein. Sensoriese integrasie disfunksie word gesien as die wortel van baie leerprobleme. Die vestibulêre sisteem is direk verbind met die sensoriese en motoriese sisteme. ‘n Sensoriese integrasie disfunksie het ‘n duidelike invloed op die vestibulêre sisteem. Die vestibulêre sisteem het baie interkonneksies met baie dele in die brein, byvoorbeeld propriosepsie en die tassisteem. Doeltreffende funksionering van die sensoriese, motoriese en vestibulêre sisteme word verlang vir ‘n hoë vlak van prestasieverrigting in sport en akademie. Wanneer die vestibulêre sisteem gestimuleer word, het dit ‘n direkte positiewe invloed op die sensoriese en motoriese ontwikkeling van leerders. Die doel van hierdie studie was om te bepaal wat die persepsie van grondslagfase-onderwysers en ouers is oor die rol en voordele wat vestibulêre oefeninge te weeg kan bring in die motoriese en sensoriese ontwikkeling van leerders. Leerders in graad 1 van ‘n privaatskool, asook van grade 2 en 3 van ‘n plaasskool is gekies as deelnemers in die studie. Die keuse van leerders was op grond van die bereidwilligheid van hulle en hul ouers om aan die studie deel te neem. Leerders het ‘n vestibulêre oefenprogram drie maal per week gedoen vir die tydperk van agt weke. Observasie-vraelyste is deur onderwysers en ouers ingevul na afloop van die derde sessie elke week. Vir die vraelys het ouers en onderwysers gekyk na die verbetering in aandagspan, konsentrasie, luistervaardigheid, oogkontak, sosiale interaksie en samewerking. Onderhoude is met ouers en onderwysers gedoen na aanleiding van die observasievraelyste wat vir die agt weke voltooi is. Transkripsies van die onderhoude is gedoen en afleidings is gemaak deur analise van die observasie-vraelyste en die getranskribeerde onderhoude. Al ses die ontwikkelingsareas by beide skole het verbetering getoon oor die agt weke. Dit dui daarop dat vestibulêre oefeninge wel ‘n invloed op die sensoriese en motoriese ontwikkeling het. / Inclusive education promotes the inclusion of learners with different needs and capabilities in classes which are often too big and diverse for effective teaching. Movement as an early learning experience is necessary for optimal neural development. It influences organisation and stimulates the specific neurological systems required for optimal functioning and development of the brain. Sensory integrative dysfunction is believed to be at the root of many learning disorders. The vestibular system is directly connected with the sensory and motor systems. The vestibular system will be directly affected when a sensory integrations dysfunction presents. In fact, the vestibular system has many interconnections with almost every other part of the brain like proprioception and the tactile system. Proper functioning of the sensory, motor and vestibular systems is required for higher level performance in sport and academics. When the vestibular system is stimulated, it will result in a positive influence on the sensory and motor development of learners. The aim of this study is to determine the perceptions of foundation phase teachers and parents regarding the role or benefits of vestibular exercises in promoting learners’ motor and sensory development. Learners in Grade 1 of a private school and Grade 2 and 3 learners of a farm school in the northern Free State were selected as participants in the research. Learners were selected on the basis of the willingness of them and their parents to participate in the research. The participants did exercise sessions three times a week for thirty minutes over a period of eight weeks. Observation sheets were completed for all eight weeks, for the duration of the exercise program, by teachers and parents. These sheets were completed weekly after the third sessions in that week. The observation sheets listed concentration, attention span, listening, eye contact, cooperation, social interaction and self-esteem as developmental areas. Interviews were done after the period of eight weeks with the parents and teachers. The interviews conducted with both parties were taped and meticulously transcribed. This helped the researcher to get a better understanding of the study and to analise data and draw conclusions.All six areas of development showed improvement at both schools over the period of eight weeks. This indicates that stimulating the vestibular system promotes sensory and motor development. / Inclusive Education / M. Ed. (Inklusiewe Onderwys)
