Full textAbstract:
From 2010, the South African vocational skills education is offered by the Department of Higher Education and Training (DHET) through the Technical Vocational Education and Training (TVET) colleges. TVET colleges need to be transformed in order to empower young learners with the skills required by the various sectors of the economy. The purpose of this study was to assess the implementation of the National Certificate (Vocational) Plant Production module in Training and Vocational Education and Training (TVET) Colleges. The sample for this study is concurrent triangulation whereby complementary methods of data sources were brought together to offset each other‘s weaknesses. The sample for this study consisted of participants from three TVET colleges: one deep rural, one semi-rural/semi-urban and one urban in terms of geographical location. A total of 18 participants were interviewed: 2 subject advisors engaged by the colleges, 1 lecturer from college A, 3 lecturers from college B, 2 lecturers from college C, 4 graduates from college B, 3 graduates from college C and 3 employers .Research design for this study has features of both a survey and a case study. The mixed-method approach was applied using document analysis, questionnaires and interviews for data collection. The researcher found out that there is a disparity between the Plant Production guidelines and their implementation and assessment. Among the main reasons for failure to implement the guidelines properly are poor or inadequate infrastructure for doing practical work, high rate of student absenteeism within the investigated categories, and the high drop-out rate at Levels 2–4. To minimize the challenges in offering the Plant Production module, the study recommends that since some colleges cannot afford purchasing large sizes of land to properly implement the Plant Production guidelines, the government and the DHET should link the Primary Agriculture training to the land reform program where students can be trained under the land reform program.

Full textAbstract:
In the last years has been performed a huge number of research related to nutrients (mainly N and P) recovery from waste water in order to promote their reuse and also to avoid eutrophication. Recovering nutrient from waste water can promote the circular economy, minimize the environmental footprint of waste water treatment and reduce anthropogenic alteration of nitrogen and phosphorus natural cycle.
Among the different techniques studied, sorption is nowadays one of the most interesting alternatives as requires less energy than electrochemical or membrane technologies and sorbents can be regenerated for being reused. Thus, the overall sorption performance of different ion exchangers was characterized for nutrient recovery from waste water treatment plant effluents.
Two commercial polymeric resins doped with Hydrated Ferrous Oxide (HFO) (Lewatit FO36 and Fiban-As) were assessed for ammonium and phosphate uptake from waste water streams. Equilibrium and kinetics studies have been performed through batch experiments and the dynamic studies were carried out by fixed-bed column. The experimental study covered from the simplest monocomponent synthetic water (ammonium, phosphate solutions) to the most complex real water from waste water treatment plant (WWTP) which contains ions, TSS and organic matter.
Sorption experiments reported for both sorbents high selectivity towards phosphate ions as sorption capacity did not significantly decrease in presence of competing ions. Loaded sorbents were regenerated through alkaline and acid desorption in order to reuse resin and obtain a high concentrated phosphate solution, which could be used for high quality fertilizer production. Results in dynamic flow experiments reported up to 80% of loaded phosphate extraction, although during desorption process was observed sorption capacity decrease up to 30% after three sorption-desorption working cycles.
Besides, salt modified synthetic zeolites were assessed for being used both as one charge (di-valent forms) and reusable (mono-valent forms) sorbent. Raw zeolites provided in sodium form as well as it modification in potassium form showed high sorption capacity for ammonium uptake but poor performance for phosphate recovery from waste water streams as the sorption mechanism is mainly ion exchange. Regeneration experiments showed that both Ze-Na and Ze-K can be reused several sorption-desorption working cycles without significant sorption capacity decrease (< 5%).
Nevertheless, after salt modification to calcium and magnesium forms, the precipitation of phosphate salts was favoured obtaining hydroxyapatite and struvite in loaded Ze-Ca and Ze-Mg, respectively. As hydroxyapatite’s solubility and phosphorus availability is similar to commercial fertilizers, loaded Ze-Ca could be potentially recycled for agricultural uses.
Finally, an economic assessment simulation was performed by applying Ze-Ca in the Baix Llobregat Waste Water Treatment Plant, located in the Metropolitan Area of Barcelona. The study reported that the implantation Ze-Ca filtration for nutrient recovery would be economically feasible, despite that more research is required in order to fit technical issues as the loaded sorbent disposal or the capability of loaded zeolites to be used as fertilizer.En los últimos años se han llevado a cabo un gran número de estudios relacionados con la recuperación de nutrientes (sobre todo N y P) de aguas residuales con el fin de promover su reutilización y evitar la eutroficación . Recuperar nutrientes de aguas residuales puede promover la economía sircular , minimizar la huella de los tratamientos de aguas residuales, así como reducir la alteración antropogénica del ciclo natural del nitrógeno y el fósforo. Entre las diferentes técnicas estudiadas, la sorción es actualmente uno de las alternat ivas más Interesantes ya que requiere menos energía que técnicas electróquímicas o las tecnologías de membrana. Además , los sorbentes se pueden regenerar y reutilizar. Así , se ha caracterizado el comportamiento integral de diferentes sorbentes para la recuperación de nutrientes de efluentes de aguas residuales. Se evaluaron dos lntercambiadores iónicos poliméricos comerciales dopados con Óxido de Hierro Hidratado (Lewatit F036 y Fiban-As) para la eliminación de fosfato de corrientes de aguas residuales. Se llevaron a cabo estudios en equilibrio y se caracterizó la cinética mediante experimentos en discontinuo y los experimentos dinámicos se llevaron a cabo mediante columnas de lecho fijo . El estudio experimental cubrió desde soluciones monocomponentes de fosfato hasta corrientes reales de plantas de tratamiento de aguas residuales que contenían iones competidores, sólidos suspendidos y materia orgánica . Los experimentos reportaron para los dos sorbentes una alta selectividad hacia los iones fosfato, ya que no se observó una reducción significativa de la capacidad de sorción en presencia de iones competidores . Los sorbentes cargados se regeneraron mediante desorción alcalina y ácida para reutilizar el sorbents y obtener corrientes con alta concentración de fosfato, que se pueden emplear para la producción de fertilizante de alta calidad. Los resultados en columnas de lecho fijo mostraron una extracción de más del 80% del fosfato sorbido, aunque durante el proceso de desorción se vio una reducción de la capacidad de más del 30% tras tres ciclos de sorción - desorción. Además, se evaluaron zeolitas modificadas mediante tratamiento salino para ser usados tanto como sorbentes de una sola carga (en la forma divalente) como reusables (en la forma monovalente). La zeolita bruta facilitada en la forma sódica, así como la forma potásica mostraron alta capacidad para la eliminación de amonio, pero prácticamente nula capacidad de retención para los iones fosfato, ya que el mecansmo de sorción es principalmente intercambio iónico. Los experimentos de regeneración mostraron que ambas zeolitas se pueden emplear para un gran número de ciclos de sorción-desorción sin perder capacidad (<5%). Tras la modificación salida a las formas cálcica y magnésica, se favorece la precipitación de sales fosfóricas obteniendo hidroxiapatita y estruvita en la Ze-Ca y Ze-Mg cargada, espectivamente. Dada que la solubilidad de la hidroxiapatita, así como la disponibilidad del fósforo de la hidroxiapatita es similar a la de los fertilizantes comerciales, la Ze-Ca cargada puede potencialmente ser reciclado para usar en agricultura. Finalmente, se llevó a cabo una simulación económica empleando Ze-Ca en la Planta de Tratamiento de Aguas Residuales de El Baix Llobregat, situada en la Area metropolitana de Barcelona. El estudio reveló que la implantación de un filtro de Ze-Ca para la recuperación de nutrientes puuede ser económicamente viable , aunque se requieren más estudios para dar solución a aspectos técnicos como la gestión del sorbente cargado o la capacidad real de las zeolitas cargas de ser utilizadas como fertilizantes

Falk, Thomas. "Safety Reviews of Technical System Modifications in the Nuclear Industry." Licentiate thesis, KTH, Filosofi, 2013. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-118843.
Full textAbstract:
The function of safety reviews (here understood as expert judgements on proposals for design modifications and redesign of technical systems in commercial Nuclear Power Plants, supported by formalised safety review processes) plays a fundamental role for safety in nuclear installations. The primary aims of the presented case studies includes: critically examining and identifying the main areas for improvement of the existing technical safety review process as it is conducted at a Swedish nuclear power plant, developing a new process, and evaluating whether any improvements were accomplished. By using qualitative methods, observation/participation and interviews, data has been gathered on how the safety review process is perceived and conducted by experts involved in the safety review process, and ways to improve this process have been developed. This area is neglected in the larger safety literature. The novel approach here is to gather data directly from those involved in the safety review process, analysis of safety review reports as well as from inspection reports by the regulatory authority. The study presented in paper I shows that the partition between primary and independent review is positive, having supplementary roles with different focus and staff with different skills and perspectives making the reviews. The study identifies a number of areas for improvement, such as: - a tendency to put too much resource on minor assignments - a clearer prioritization would improve focus on the most critical projects - there is a need for improved guidance and direction for how to structure the work It is argued that future applications of safety review processes should focus more on communicating and clarifying the process and its adherent requirements, and improve the feedback system within the process. It is also recommended that the NPPs create introductory training for new reviewers The study presented in paper II concluded that grading of the primary safety review reports facilitates improved experience feedback by providing easier access to good examples for reviewers. Improvements identified by implementing the revised process are primarily linked to the independent safety review function, including better planning and means for resource allocation as well as clearer and more unambiguous supporting instructions. Introduction of formalized independent review meetings provides increased exchange of knowledge and strengthened the independent safety review function in the organization.QC 20130305

Full textAbstract:
The drinking water plant in this case study is a combined groundwater and reverse osmosisplant in the Stockholm archipelago. The reverse osmosis purification step was added to theplant in 1995. This technique is relatively new in Sweden and there are possibilities for it tobecome a good complement to conventional drinking water treatment. The plant has used thistechnique for over 10 years with good results. It is therefore of great interest to evaluate anddocument it for the possibility to implement this technique in areas not connected toconventional drinking water production.Reverse osmosis separates the incoming water to a clean permeate and concentrate ofremoved particles, larger molecules and ions. This technique has a high purification degree. Itcan remove dissolved particles and microorganisms without disinfection. However, it isrelatively expensive due to a high electricity consumption compared to conventional drinkingwater treatment. The high electricity consumption in this kind of system depends on aphenomenon called membrane fouling caused by the constituents in the raw water, graduallybecoming enriched on the membrane surface.The aim of this thesis was to evaluate and document a drinking water plant in the Stockholmarchipelago from a social, economical, technical and environmental perspective. A socialsurvey in the form of a questionnaire was conducted to reveal opinions about the water qualityprovided by the plant. The economical evaluation was done to estimate the cost of drinkingwater production and find the water cost in Kr/m3. The technical part involved documentationof the plant layout and evaluation of its performance. To assess the performance historicalchemical and microbial analyses were evaluated. A mass balance was attempted to drawconclusions for the overall system. The environmental part of the plant assessment, includedan estimate of the electricity and chemicals use in the plant.The results revealed that from an overall perspective the water quality from the plant issatisfactory with some concerns about metal taste and turbidity that sometimes occur. Thepotential presence of dangerous algal toxins in the water was also a concern. The totalproduction cost in Kr/m3 is higher than expected and higher than sales price. In technicalterms, the plant has functioned well. However, there is a need to monitor more parameters inthe plant including; more flow parameters, concentrations of added chemicals and more waterquality parameters. Electricity consumption has been higher than expected. Control(throttling) valves in the brine reject are relatively large energy consumers and arecommendation is to investigate potential savings by changing them for pressure exchangevalves.www.ima.kth.se

Full textAbstract:
This thesis reflects upon several decades of research into Lean Production systems, highlighting the need for further investigation using an empirical study of exemplar implementations of Lean. The initial point of departure is an analysis of the current views of Lean based on a detailed literature review. The resulting Views of Lean Table provides a framework for the investigation of an exemplar Lean operation, viz the Nissan Sunderland Plant, widely regarded to be one of the most productive automotive plants in Europe. The exploratory nature of this investigation, and unique opportunity for access, argued for the use of an inductive single case study as an appropriate research approach. A four phase approach was used to; a) identify views of Lean, b) gain an initial understanding of the Nissan Production Way at the Nissan Sunderland Plant, b) acquire a detailed description of the Nissan Production Way and c) to assess the level of intrinsic motivation amongst employees. The primary objective of this research is to establish whether our current knowledge of Lean sufficiently encapsulates the concept’s many facets. Detailed semi-structured interviews with Nissan Production Way experts revealed that Nissan Sunderland Plant’s production system uses a large number of elements in contrast to the relatively narrow list of ‘Lean’ elements cited in the Views of Lean Table. In contrast to academic theory there was a focus on extrinsic motivation with low intrinsic motivation offset by the plant’s continuous fight for survival and ‘whatever-it-takes’ attitude. In practice Lean is viewed as an overarching philosophy with a toolkit encompassing a wide range of tools which are used when they are suitable for the task in hand.

The following work is the result of an internship carried out at STC POWER Company, in the proposal office, with the aim to make a technical comparison of two combustion technologies, Moving Grate (MG) and Circulating Fluidized Bed (CFB), in order to find out which is the optimal solution for a specific biomass power plant.
After a preliminary description of the fuel considered (biomass) and an overview of the operating principle of a combined heat and power (CHP) plant, the attention has been paid to the main differences of the two boilers, focusing on: fuel characteristics, pollutant emissions, corrosion and fouling problems, performances and auxiliaries.
Then, the technical comparison has been applied to a biomass CHP plant that will be realized in France following a tendering process to which STC Power is participating. The overall power plant has been simulated with the software Thermoflex both with MG boiler and CFB boiler and, after several optimizations, the results in terms of performances and efficiencies have been compared. Particularly critical has been the corrosion problem, caused by the fuel composition, that has led to a limitation on the maximum temperature of the steam produced with MG boiler, thus limiting also the overall efficiency of the plant.
After the technical analysis, also the economic aspects have been evaluated, with a comparison of the main costs (CAPEX and OPEX) of MG and CFB boilers.
Finally, the reasons that have led to choose one specific boiler instead of the other have been explained.

Full textAbstract:
The current shift towards renewable energy resources creates volatility in the electricity production that must be compensated by nevi sources of balancing energy. To ensure a normal operation of the power system, the transmission system operators procure power reserves able to provide regulation energy through market processes. Virtual power plants are now likely to participate on the balancing markets. In this study, the technical and economic feasibility of having virtual power plants participate in the Swiss balancing market is assessed. The study begins with the evaluation and compa.rison of four European balancing market designs and continues with the clarification of the concept of virtual power plant. The focus is then set on the Swiss ancillary services market, recently open to virtual pmver plants. After a detailed market description, an economic model simulating the participation of a virtual power plant made of industrial resources on the secondary and tertiary control markets has been developed. This model \Vas evaluated on an actual market design: the Sv.riss ancillary servicel:l market. 5 cases were simulated, allowing to estimate the opportunity fom both the capacity and the energy market productl:l. The simulations indicated that an example company (based on an actual situation) could hope a decrease in its energy cost between :3 and 4% by participating in a control pool over a year. Other simulations demonstrated the greater profit expected from secondary reserves compared to tertiary rel:lerves, and the need to develop an automatized activation system. The encouraging economic study is followed by a technical overview of the envisioned system. A generic technical characterization of virtual power plant is presented, on v.rhich the Swiss use-case is later applied. The breakdown into functional requirements allowed to highlight specific issues. The design of the control strategy, particularly to deliver secondary control, as well as the hardware communication interface to use are tvw aspects that ,vill require further analysis. Additionally, on an economic level, the investment cost for remote communication modules are acceptable with respect to the economic potentials estimated in the first part, for mediumsized industrial energy resources. In conclusion, the study established the profitability of an aggregation project on the Swisl:l market but also demonstrated the need to pursue research for the project to be fully feasible on a technical level.

"Detecting and characterizing the highly divergent plastid genome of the nonphotosynthetic parasitic plant Hydnora visseri (Hydnoraceae)." Saechsische Landesbibliothek- Staats- und Universitaetsbibliothek Dresden, 2016. http://nbn-resolving.de/urn:nbn:de:bsz:14-qucosa-203345.
Full textAbstract:
Plastid genomes of photosynthetic flowering plants are usually highly conserved in both structure and gene content. However, the plastomes of parasitic and mycoheterotrophic plants may be released from selective constraint due to the reduction or loss of photosynthetic ability. Here we present the greatly reduced and highly divergent, yet functional, plastome of the nonphotosynthetic holoparasite Hydnora visseri (Hydnoraceae, Piperales). The plastome is 27 kb in length, with 24 genes encoding ribosomal proteins, ribosomal RNAs, tRNAs and a few non-bioenergetic genes, but no genes related to photosynthesis. The inverted repeat and the small single copy region are only ~1.5 kb, and intergenic regions have been drastically reduced. Despite extreme reduction, gene order and orientation are highly similar to the plastome of Piper cenocladum, a related photosynthetic plant in Piperales. Gene sequences in Hydnora are highly divergent and several complementary approaches using the highest possible sensitivity were required for identification and annotation of this plastome. Active transcription is detected for all of the protein coding genes in the plastid genome, and one of two introns is appropriately spliced out of rps12 transcripts. The whole genome shotgun read depth is 1,400X coverage for the plastome, while the mitochondrial genome is covered at 40X and the nuclear genome at 2X. Despite the extreme reduction of the genome and high sequence divergence, the presence of syntenic, long transcriptionally-active open reading frames with distant similarity to other plastid genomes and a high plastome stoichiometry relative to the mitochondrial and nuclear genomes suggests that the plastome remains functional in Hydnora visseri. A four stage model of gene reduction, including the potential for complete plastome loss, is proposed to account for the range of plastid genomes in nonphotosynthetic plants.

Full textAbstract:
Extreme haustorial parasites have long captured the interest of naturalists and scientists with their greatly reduced and highly specialized morphology. Along with the reduction or loss of photosynthesis, the plastid genome often decays as photosynthetic genes are released from selective constraint. This makes it challenging to use traditional plastid genes for parasitic plant phylogenetics, and has driven the search for alternative phylogenetic and molecular evolutionary markers. Thus, evolutionary studies, such as molecular clock-based age estimates, are not yet available for all parasitic lineages. In the present study, we extracted 14 nuclear single copy genes (nSCG) from Illumina transcriptome data from one of the “strangest plants in the world”, Hydnora visseri (Hydnoraceae). A ~15,000 character molecular dataset, based on all three genomic compartments, shows the utility of nSCG for reconstructing phylogenetic relationships in parasitic lineages. A relaxed molecular clock approach with the same multi-locus dataset, revealed an ancient age of ~91 MYA for Hydnoraceae. We then estimated the stem ages of all independently originated parasitic angiosperm lineages using a published dataset, which also revealed a Cretaceous origin for Balanophoraceae, Cynomoriaceae and Apodanthaceae. With the exception of Santalales, older parasite lineages tend to be more specialized with respect to trophic level and have lower species diversity. We thus propose the “temporal specialization hypothesis” (TSH) implementing multiple independent specialization processes over time during parasitic angiosperm evolution.

Full textAbstract:
The safety record of most petrochemical industries in the world and Nigeria in particle, has not been able to come down to the maximum allowable range of 0 - 0.1 percent of tolerance on recordable injuries, due to increasing failure rates of equipment within the plant. Investigations on the maintenance audit carried out on the Nigerian Gas Company (NGC) revealed that 85 percent of such failures are directly linked to improper adaptability of an effective maintenance management strategy and plan within the petrochemical industries in Nigeria.
Equally, the growth and continuous operation of any plant depends to a large extent on the maintenance of the equipment that refines the Crude Oil and natural Gas. As such, various maintenance management systems have been used over the years for the actualisation of the above purpose but with minimal success. This is evident in the fact that the level of maintenance performance of most Nigerian Petroleum Companies is always on the corrective maintenance model, which indirectly implies that the plant normally breaks down before maintenance management is applied.
A critical look at the deficiency of improper adaptability of these maintenance management plans have conspicuously manifested in five major categories of maintenance failures which includes the following;
* Failure of safety critical equipment due to lack of maintenance
* Human error during maintenance
* Static or spark discharge during maintenance in an intrinsically unsafe zone
* Incompetence of maintenance staff, and
* Poor communication between maintenance and production staff.
These gaps as identified in this research must be corrected in the Nigerian Gas Industry if meaningful progress is to be made.
Gas – To – Liquid technology is a very complex technology and with natural gas as the basic raw material, the technology not only looks intimidating but also is full of potential hazards. People are naturally afraid of the complex nature of gas in a confined environment (because of its highly combustible nature), its gaseous state makes it more complex for it to be kept under control and at the same time be moved from one form to another at different temperatures and pressures.
The maintenance audit carried out on the Nigerian Gas Company (NGC) revealed some major loopholes in the maintenance management strategies adopted in the country. The audit reveals that the degree of adherence to conditions attached towards the maintenance management strategy of this equipment (in this case Gas field equipment) was too poor.
Based on the above, this research is meant to improve the existing maintenance management strategy, by developing a Maintenance Management Strategy (MMS) that will be suitable for gas field equipment in the Escravos Gas–To– Liquid (EGTL) plant, planned to be commissioned in Nigeria early 2011.
The need to research the above mentioned Maintenance Strategy became imperative due to the fact that the rate at which most of the petrochemical plants in the world are being gutted by fire, mainly due to poor maintenance management systems is alarming.
This research work proffered solutions that will reduce or completely eliminate the highlighted problems above. This was based on investigations and analysis carried out in the chosen research area.
Models were developed for the actualization of this Improved Maintenance Management Strategy (IMMS), so that the desired safe operability of the gas field equipment in the Escravos Gas–To– Liquid (EGTL) plant will be achieved without maintenance failure of any kind.Thesis (M.Ing.

L’utilisation excessive des produits phytosanitaires provoque des problèmes de santé publique et environnementaux du fait de leur toxicité. Dans le cadre de ce travail de recherche interdisciplinaire entre géographie et agronomie, l’objectif est d’analyser la résilience des exploitations agricoles et leur capacité à faire face au changement des pratiques phytosanitaires. Pour y répondre, nous nous sommes basés sur la conception d’une méthode d’évaluation des pratiques phytosanitaires à différentes échelles spatiales et d’un modèle technico-économique d’optimisation des traitements phytosanitaires et de gestion des risques liés aux pesticides. Ce travail consiste à mettre à la disposition des acteurs du territoire des outils d’aide à la décision pour une gestion intégrée de l’usage des pesticides au niveau du bassin versant de l’étang de l’Or au Sud de la France. Cette étude est basée sur l’utilisation de plusieurs outils pluridisciplinaires : les techniques de programmation mathématique, d’analyse statistique et les Systèmes d’Informations Géographiques (SIG), en introduisant des indicateurs agri-environnementaux de pression phytosanitaire (IFT) et de risque de toxicité sur la santé de l’applicateur et sur l’environnement (IRSA, IRTE), ainsi que des indicateurs économiques. La combinaison de ces indicateurs définit les différentes catégories de résilience des exploitations agricoles et la capacité de leur système de production à faire face au changement de pratiques phytosanitaires. Ce concept de résilience, associé à l’analyse spatiale des indicateurs agri-environnementaux et économiques à l’aide d’un SIG, permet de mettre en place des outils génériques d’aide à la décision afin de trouver un compromis entre les différents acteurs pour faire face aux problématiques de l’iniquité spatiale et socio-économique de la pollution phytosanitaire diffuse. Les résultats d’analyse multi-échelle permettent la mise en place des stratégies de gestion des risques liés aux pratiques phytosanitaires en fonction de la vulnérabilité du milieu naturel sur un territoire et en assurant des résultats économiques convenables aux exploitations agricolesThe excessive use of plant protection products has caused public health and environmental issues dueto their toxicity. As part of this interdisciplinary research work between geography and agronomy, theobjective is to analyse the resilience of farms and their capacity to deal with the change of plantprotection practices. In order to answer this objective, our work is based on the design of a method forassessing plant protection practices at different spatial scales and on a technical-economic model foroptimising plant protection treatment and managing risks related to pesticides. This work consists inproviding territorial actors with decision-support tools for an integrated management of pesticide useat the “Etang de l’Or” catchment area in the South of France. This study is based on the use of severalmultidisciplinary tools: mathematical programming techniques, statistical analysis and GeographicInformation Systems (GIS), by introducing agri-environmental indicators for plant protection pressure(TFI) and risks of toxicity on the applicator’s health and on environment (IRSA, IRTE), and economicindicators. The combination of these indicators defines the different categories of farms resilience andcapacity of their production systems to deal with the change of plant protection practices. The conceptof resilience, combined with spatial analysis of agri-environmental and economic indicators usingGIS, allows implementing generic decision-support tools to find a compromise between the differentactors to deal with problems of spatial inequality and socioeconomic in term of phytosanitary diffusepollution. The results of multi-scale analysis allow implementing management strategies of risksrelated to plant protection practice based on the vulnerability of the natural environment on a territoryand ensuring suitable economic outcomes to farms

Full textAbstract:
Danggui Buxue Tang (DBT), a herbal decoction containing Astragali Radix (AR) and Angelicae Sinensis Radix (ASR), has been used in treating menopausal irregularity in women for more than 800 years in China. Pharmacological results showed that DBT exhibited significant estrogenic properties in vitro, which therefore suggested that DBT could activate the nuclear estrogen receptors. Here, we assessed the estrogenic properties of DBT in an ovariectomized in vivo rat model: DBT was applied to the ovariectomized rats for 3 days. The application of DBT did not alter the weight of uterus and liver, as well as the transcript expression of the proliferation markers including the estrogen receptors α and β. However, DBT stimulated the transcript expression of the estrogen responsive genes. In addition, the inductive role of DBT on the expression of members of the aryl hydrocarbon receptor family in uterus and liver of ovariectomized rats was confirmed. These responses of DBT however were clearly distinct from the response pattern detectable here for 17β-estradiol. Therefore, DBT exhibited weak, but significant, estrogenic properties in vivo; however, some of its activities were independent of the estrogen receptor. Thus, DBT could be an exciting Chinese herbal decoction for an alternative treatment of hormone replacement therapy for women in menopause without subsequent estrogenic side effects.

Full textAbstract:
The alpaca is a small South American camelid (SAC) that is an important production animal in Peru, especially among the highly impoverished communities of the high Andes, and raised for its fiber and meat. Alpacas are highly reliant on the microbes within their digestive tracts to digest the plant material they consume; volatile fatty acids (VFAs) are released as a byproduct of this microbial fermentation and used as a major source of energy by the alpaca. To explore optimal parameters for alpaca microbiome analysis, performed 16S rRNA gene surveys on alpaca C1 and fecal samples that had been extracted using one of three different DNA extraction methods (PowerFecal® DNA Isolation Kit (MO BIO); ZR Fecal DNA MiniPrep™ (Zymo); and a non-commercial extraction method called salting out) and amplified using one of two different polymerase enzyme mixes (AccuPrime™ Pfx SuperMix and 5 PRIME HotMasterMix). We found that choice of polymerase enzyme had a profound effect on the recovered microbiome, with the majority of 5 PRIME-amplified fecal samples failing to amplify. Extraction method had an effect on the recovered microbiome of fecal samples (but not C1 samples), with samples extracted using the MO BIO kit and the salting out method recovering different communities. The Zymo extraction kit returned microbial communities comparable to each of the other extraction methods. These results suggested that the AccuPrime enzyme and either the MO BIO or Zymo kits were optimal for alpaca gut microbiome analysis. We also performed two 16S rRNA gene surveys, the first from alpacas fed either a grass hay (GH) or alfalfa hay (AH) diet, and the second a C1 survey of alpacas fed two-week periods of mixed grass hay plus one of four supplements. We discovered body site and diet effects on the microbiota of alpacas fed either the GH or AH diet, with samples grouping by general body site (C1, small intestine, and distal intestine) and diet. However, we found no significant effect on the C1 microbiome of alpacas administered grain supplements. To study how energy extraction related to the microbiome, we correlated OTUs from GH/AH-fed alpaca with C1 VFA abundances. We discovered no significant correlations, and a 16S survey of low body condition (LBC) and good body condition (GBC) alpacas showed no difference in C1 microbial communities. We concluded that the microbiota of the alpaca digestive tract follow trends seen in microbiome studies of ruminants, but found no evidence of a relationship between body condition, energy extraction, and the C1 microbiome in alpacas.

Full textAbstract:
This diploma thesis is mainly focused on the digestate thickening in a biogas plant. First, overview of the biogas technology in the Czech Republic is presented. Furthermore, problems with waste heat utilization and processing of fermentation residues (digestate) are described in more detail. Based on the research, multi-stage flash (MSF) evaporation was chosen as the technology for the digestate thickening. The main part deals with the integration of the chosen technology into a biogas plant process. The programming language Python was used to simplify the given task. In the preliminary stage, a complex mathematical model of a biogas plant was created, focusing particularly on the mass and energy balances. Subsequently, a computational model of the MSF evaporator was programmed. A procedure for the integration was suggested using the sensitivity analyses. Additionally, the model of a biogas plant was extended with the MSF evaporator. The key outcome of the thesis is a technical-economic analysis in which the impact of digestate transport price and electricity feed-in tariff on payback period is investigated. The results suggest profitability of MSF evaporator for biogas plants without subsidized feed-in tariff. Contrastingly, installation of MSF evaporator in older biogas plants with subsidized feed-in tariff can be economically viable only in cases of significantly longer transport distances.

The subject of this thesis is to create evaluation criteria of technical condition of water treatment plants. The thesis is divided into four parts. In the first part of this thesis are presented evaluation systems by performance indicators drinking water treatment plants, which are then applied in real time. There are detailed descriptions of individual performance indicators. Each evaluation conducted certain period of time. After the expiry of the period under review was to evaluate and create charts to display results. In the next chapter the thesis focuses on the identification data. First, it was necessary to find out all necessary information about the water treatment plant. Necessary information means information relating to building construction, human resources, mechanical parts, technological equipment and other entities with links to the operation of the water treatment plant. All these data were sorted for better overview and facilitate setting evaluation indicators. The third part of this thesis is focused on the development of indicators that are used to determine the current status of the water treatment plant. As a first step was established 19 indicators used to evaluate the condition of the entire water treatment plant. Followed by a description of the individual indicators and then determine the individual evaluation criteria. In the last part of this thesis was carried out by the proposed criteria on selected water treatment plants. They were selected three water treatment plants located in the Czech Republic, which held a personal tour of each water treatment plant. This was followed by an overall assessment of the technical condition of water treatment plants.

ABSTRACT
TECHNICAL AND APPLIED FEATURES OF FUNCTIONAL BEHAVIORAL ASSESSMENTS AND BEHAVIOR INTERVENTION PLANS
by
Shannon M. Hawkins
When conducted correctly, functional behavior assessments (FBAs) can help professionals intervene with problem behavior using function-based interventions. Despite the fact that researchers have shown that effective interventions are based on function, recent investigators have found that most behavioral intervention plans (BIPs) are written without regard to the function of students’ problem behaviors as documented in their FBAs. This study was conducted to examine the overall technical adequacy of FBAs and BIPs within one educational system to evaluate reliance on the outcomes of FBAs in the development of BIPs. The technical and applied features of a randomly selected sample of 134 FBA/BIPs of students with disabilities, ages 3-21 years, who were receiving services due to their severe emotional and behavioral disorders (SEBD) or autism spectrum disorders (ASD) within the Georgia Network of Educational and Therapeutic Services (GNETS) were analyzed. In addition, similarities and differences between function-based strategies specified in BIPs were examined. Logistic regression was used to reveal the probability that a given behavioral function can predict which intervention(s) might be chosen. A series of chi-square tests of independence and a multinomial logistic regression model were used to examine how BIP component variables, demographic variables, behavioral function variables, and behavioral intervention variables related to each other statistically. Components described as critical in research literature for conducting FBAs and developing BIPs were absent from a significant number of the student files. Results suggest few of the prescribed interventions were likely to be related to function. The findings extend research on FBAs and BIPs, particularly as they are used with students with SEBD and autism, documenting that a significant number of BIPs are developed without regard of the function of the problem behavior.

Full textAbstract:
Behavior Intervention Plans (BIPs) are legally binding documents required by the Individuals with Disabilities Education Act (IDEA) for students with disabilities. These plans are intended to help teachers use positive, function-based interventions to decrease problem behaviors and promote functionally-equivalent appropriate social behaviors. The Behavior Intervention Plan Quality Evaluator (BIP-QE II) identifies six components of BIP technical adequacy including behavior function, situation specificity and behavior change, reinforcement tactics, reactive team strategies, team coordination and goals and objectives. Unfortunately, in practice BIPs often lack these key components, which can lead to ineffectiveness of plans, as well as lack of communication among team members and low implementation fidelity, leading to poor student outcomes. In this study, the research team evaluated the effects of providing feedback to plan developers on the technical adequacy of BIPs, using the BIP-QE II. The study employed a waitlist control group experimental design where five participants in the treatment group received feedback immediately and four the control group received feedback after a short delay. In addition, previous research suggests that feedback is only as valuable as participants perceive it to be so. A social validity interview confirmed that feedback was valuable to participants but there was a perception that external reviewers did not appreciate some important contextual factors impacting participants' work. Feedback to support the technical adequacy of BIPs is a promising practice that appears both effective and efficient and deserves further research, refinement, and exploration.

Thesis (MBA)--Stellenbosch University, 2014.ENGLISH ABSTRACT: A sound strategic approach to the management of the Mine Technical Services (MTS) department at Styldrift is critical. There are numerous areas of influence that play a role in the success or failure of the department. All these influences have an impact on each other and these influences need to be carefully understood. Within the MTS department there are also several subdepartments that have to be staffed, equipped and managed very well in order to get the best interdependent relationship between departments as possible. It is only through this interdependent relationship that the department can function complementarily and excel in achieving its strategic goals. Mineral resources at a mine are managed through the services from the mine technical team. There are few strategic documents in the mineral resource management (MRM) field that provide a guideline to set up a department successfully. Departments throughout the country operate on different levels with different standards without the knowledge shared from the one section to the next. For the purpose of this assignment, some of the ground principles were investigated and documented to create a link between departments, mines and companies to enable the move towards operational excellence within the MTS. Through the application of relevant literature, research was conducted on the industry to determine best practices. The industry best practices are discussed and referenced to Styldrift Specific. The strategy and management philosophy were evaluated and are highlighted in this assignment. With the literature firmly understood and the required direction from the company placed in perspective, the strategy for the MTS department could be crafted to an extent that it can be executed. Each department was broken down to manageable elements to understand the functioning of the department. The fundamental OR requirements were evaluated and are stipulated in this paper. The MTS department was then dissected through the available theory to guide the process of crafting and executing the departmental strategy. The journey through to operational excellence and the fundamental guideline of crafting and executing a strategic plan for an MTS department to manage mineral resources become clearer as the chapters of the assignment are completed. The end goal of the project was to have a document that can guide staffing, equipping and management of the MTS department at Styldrift in order to ensure success for the project, mine and surrounding communities.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIROApesar dos avanços verificados nos últimos anos, o aproveitamento energético do biogás no Brasil ainda não é uma prática consolidada no tratamento de esgotos. Em estações de tratamento de esgotos (ETEs) com processos anaeróbios, o biogás se mostra como um produto estratégico econômico, social e ambientalmente, em muitos países do mundo, em especial na Alemanha. O projeto de cooperação técnica Brasil-Alemanha – PROBIOGÁS – foi o propulsor da discussão do biogás no saneamento no país. O presente trabalho retrata as principais ações e impactos do PROBIOGÁS no setor de tratamento de esgotos brasileiro e propõe uma continuidade às ações desenvolvidas por meio de instituições chave. Além disso, são levantados os desafios e perspectivas do biogás no setor, usando como base o histórico na Alemanha. No âmbito do PROBIOGÁS, os resultados foram bastante exitosos e consolidam as bases para o avanço do tema no Brasil. Como legados do projeto, desenvolveram-se diversas referências técnicas nacionais, promoveu-se a integração de diversos atores chave, fomentou-se a pesquisa aplicada e foram desenvolvidas capacidades de mil e oitocentas pessoas. Apesar disso, ainda se faz necessário que todo o conhecimento produzido seja replicado para as diversas realidades no país. Além disso, os principais desafios passam pela fragilidade da estratégia de gestão, pouca integração entre o desenvolvimento científico e sua aplicação, e necessidade de desenvolvimento de capacidades. Por fim, fica claro que, para o desenvolvimento de projetos de biogás de ETEs bem-sucedidos torna-se indispensável a incorporação do conceito de ETE Indústria.
The current context of sewage treatment in Brazil is critical: only 40 percent of all generated wastewater is treated (ANA, 2015). Therefore, the expansion of the provision of sewage treatment services must take place within a scenario of investment difficulties, more stringent quality standards, higher energy and sludge operation costs and sewer rates that do not reflect real costs. Given that the provision of this service is not compromised and to move forward effectively on this issue, a change in management and paradigm breakdown must be done by establishing the concept of Industrial waste water treatment plant (WWTP). This concept envisions the WWTP as a closed loop, which receives an effluent for treatment and that through the efficiency of its processes delivers a treated effluent, seeking to optimize costs, recover and value the by-products and promote public health, based on a sustainable servicing of the institutional, social, environmental and economic dimensions. One of the potential by-products of sewage treatment is the biogas. This is because the UASB reactors for the treatment of domestic sewage is consolidated in the country (VAN HAANDEL et al., 2006; CHERNICHARO et al., 2015), considering the WWTP in operation, in different sizes and in the projects contemplated by the Growth Acceleration Program (PAC, in Portuguese). Chernicharo (2017) counted 908 anaerobic reactors that serve about 23 million inhabitants and routinely produce biogas. Considering the diagnosis of WWTPs carried out by the Agência Nacional de Águas - (2016), a Brazilian water agency, it shows that more than a third of the plants use anaerobic reactors. By transforming biogas from a by-product of the treatment process into a renewable energy source, WWTP also promotes a new level of service delivery, generating distributed energy that provides an improvement in the management of its energy and in the treatment processes. From the point of view of service provision, biogas plays a strategic role because it acts as a fuel to promote a sustainable service from a social, environmental and economic perspectives.

Atchley, Carly Parkinson. "An Evaluation of Behavior Intervention Plans: Consideration of the Interventionist and Contextual Fit." BYU ScholarsArchive, 2021. https://scholarsarchive.byu.edu/etd/9125.
Full textAbstract:
Behavior Intervention Plans (BIPs) are used in public schools for students with disabilities, replacing target behaviors with socially appropriate behaviors using positive behavior support strategies. However, research suggests that BIPs are often poorly written or fail to be implemented as intended. One reason for the ineffectiveness of BIPs may be that the interventionist (e.g., classroom teacher or other staff member responsible for implementing the plan) and the context of his/her classroom is not considered when plans are written by specialists (e.g., school psychologist, special education teacher, etc.). The purpose of this study was to evaluate BIPs written and used for students in public schools in the intermountain west for their contextual fit, using a researcher-developed measure of contextual fit based on key concepts previously established in research and modeled after the Behavior Support Plan-Quality Evaluation, Second Edition (BSP-QE II). With the coding guide created by our research team, we coded previously collected BIPs for practicality, the skill level and competency required for the interventionist to implement, and the consideration of cultural values for both the interventionist and the student who would receive the intervention. In addition, a previous research study by a graduate student at the same university had previously coded BIPs from the four school districts in Utah for technical adequacy using the BSP-QE II and, using the results from that study, we ran a Pearson correlation to determine whether there was a statistically significant relationship between BIP quality and contextual fit. Ultimately, our study found that BIPs often failed to include all elements for contextual fit to reasonably be considered established, particularly in the cultural values of those who would implement or receive the plan. In addition, we found a moderate, positive relationship between BIP technical adequacy and contextual fit. Implications for practitioners and ideas for future research are also discussed, including: ensuring that BIPs are developed in teams that include the interventionist, creating BIP templates that are culturally and contextually appropriate, and the possibility of research that documents actual interventionist participation in BIP team meetings as a comparison to the results of our scoring guide of BIP contextual fit.

Full textAbstract:
This thesis comprehensively analyses photovoltaic power plants on facades both from economic and technical point of view. It also devotes to a broader view upon a photovoltaic power plants regarding their placement, its accessories and legislative. The thesis describes a calculation of energetic gains in details including evaluation of five solar radiation sources in order to assess energetic effectivity of the photovoltaic equipment. Furthermore, the thesis describes a means of determination of photovoltaic revenues which is closely related to its ability to sustain the energetic demand of the building. These calculations are presented in the conclusion of thesis where they are applied to four selected buildings. The thesis also contains a processed graph due to which it is possible to specify optimal size of photovoltaic facade. The size is depending on selected facade cardinal point orientation and also on floor area of the building, which serves to estimate future electricity consumption.

Full textAbstract:
• Autotelic Architecture is a collection of buildings with architectural stories. • The buildings included are described with black line drawings on white paper and a supplementary text. The drawings have been stripped down to only show walls, pillars, stairs, ramps and significant objects. Together the drawing and the text describes what story is told in the building through its architectural elements. • The reason to include a building in the collection is our recognition of a story within it. • All of the buildings in the collection have been built. • Each of the buildings in the collection hold a story thought of as relevant, communicated with spaces and objects. The relevance is based on an incomplete set of attributes, indicating a strong architectural story. • The buildings are categorized in different themes. For example, the theme of labyrinths describe buildings that are of a maze like nature, schizophrenic describe buildings with multiple logics and nothingness describe buildings appearing to be almost nothing. One building can be part of several themes, and the number of themes is not fixed. • The intention is to visualize the nature of the architectural story and to provide a conceptual inventory for further development of architectural stories. We believe that from telling stories with only the configuration of a buildings physical conditions there arises a direct intellectual stimulation which adds poetic depth to the building. • This book argues that the poetical aspects of architecture has a purpose in itself and should take precedence over the technical aspects. • This book is not a manual and can therefore not be seen as dogmatic or as a recipe for architecture. It is a body of strong architectural stories that deserve to be noted and shared. • This book does not take a stand against other forms of architecture, it simply proposes a language of designing that is both serious and happy, both literal and tentative, both enigmatic and real.• Autotelisk Arkitektur är en samling av byggnader med arkitektoniska berättelser. • Byggnaderna är beskrivna med hjälp av planer och text. Planerna har blivit reducerade för att enbart visa väggar, pelare, trappor, ramper och signifikanta objekt. Tillsammans beskriver planen och texten den berättelse byggnaden berättar genom sina arkitektoniska element. • Alla byggnader i samlingen har byggts. • Byggnaderna är kategoriserade i olika teman. En byggnad kan vara part av flera teman och antalet teman är inte fast. • Intentionen är att visualisera arkitektoniska berättelser och tillgängliggöra en konceptuell inventering för vidare utveckling av arkitektoniska berättelser. Vi tror att genom att berätta historier genom enbart en byggnads rumsliga konfiguration uppstår det en intellektuell stimulering vilket skapar poetiskt djup i en byggnad. • Boken föreslår ett formgivningsspråk som är både seriöst och glatt, både bokstavligt och sökande, både enigmatiskt och verkligt.

Full textAbstract:
Hospital Information System (HIS) is considered as an important factor in health care sector for managing the administrative, financial and clinical aspects of a hospital. A large number of hospitals from both developing and developed countries are adopting hospital information system to bring efficiency in their current system. Current study is conducted to contribute to the literature regarding HIS implementation in developing country settings as there is scarce literature. This study attempts to improve the understanding of HIS implementation in developing countries. In this study, socio technical model is used to understand the current working system of cardiology department of Combined Military Hospital (CMH). Qualitative case study is conducted for this research. Data is collected with the help of interviews done online via Skype and some secondary data resources to highlight the problems and solutions before HIS implementation. The data collection, generation of results and analysis is done on the basis of structure, people, technology, and process perspective originating from the socio-technical model. Findings of this study are presented in the form of recommendations which need to be considered for making a HIS implementation plan.
