Abstract:
A field experiment was conducted for investigation of different phosphorus fertilizer sources and their importance in rapeseed farms on 2007 at Arak, Iran. Ammonium phosphate fertilizer with 50% P2O5 (APF) was as chemical phosphorus sources with 3 rates of application and Phosphor solublizing bacteria (PSB) was as biological phosphorus surcease in 4 levels. Experiment was factorial arrangement in randomized complete block design with 3 replications. APF levels were control (AP0), 125kg/ha APF (AP1) and 250kg/ha (AP2) application and PSB levels were, control (PSB0), PSB at sowing time only (PSB1), PSB as top dress fertilizer after over wintering only (PSB2) and PSB at dual fertilizing in sowing time and also after over wintering (PSB3). The statistical analyses were showed that the PSB3 treatment was a great treatment for increasing seed yield. The heist rate of seed yield was recorded at 9.9t/ha under dual fertilizing in sowing time and after rosette over wintering stage. The interaction effects of phosphorus solublizing bacteria and ammonium phosphate fertilizer application had not significant effect on plant height, biomass yield, number of silique per plant, seed oil percent and seed yield. Interaction effects of phosphorus solublizing bacteria and ammonium phosphate fertilizer application were significant for plant tissues phosphorus content.

Abstract:
Active Power Filter (APF) is capable of changing the size and frequency of harmonics as well as changes in reactive power compensation. It is important to control the stability of the DC-link capacitor voltage stability for it. For DC voltage controls of APF, there are two important achievements. First, it is indicated that the control of DC voltage directly affects the compensation performance of APF. Second, the value of DC voltage influences the power loss of APF. This paper firstly introduces the design of the DC voltage controller. Then the relationship between DC voltage and the power loss as well as the compensation performance of APF is analyzed. Finally, a new control scheme with a droop controller is developed to regulate DC voltage.

Abstract:
This paper presents a thorough study of the adaptive sliding mode technique with application to single-phase shunt active power filter (APF). Based on the basic principle of single-phase shunt APF, the approximate dynamic model is derived. A model reference adaptive sliding mode control algorithm is proposed to implement the harmonic compensation for the single-phase shunt APF. This method will use the tracking error of harmonic and APF current as the control input and adopt the tracking error of reference model and APF output as the control objects of adaptive sliding mode. In the reference current track loop, a novel adaptive sliding mode controller is implemented to tracking the reference currents, thus improving harmonic treating performance. Simulation results demonstrate the satisfactory control performance and rapid compensation ability of the proposed control approach under different conditions of the nonlinear load current distortion and the mutation load, respectively.

Abstract:
An adaptive fuzzy control system with supervisory controller is proposed to improve dynamic performance of three-phase active power filter (APF). The proposed adaptive fuzzy controller for APF does not build an accurate mathematical model but approximates the nonlinear characteristics of APF using fuzzy approximation. The adaptive law based on the Lyapunov analysis can adaptively adjust the fuzzy rules; therefore the asymptotical stability of the adaptive fuzzy control system can be guaranteed. Simulation results demonstrate that the APF control system has excellent dynamic performance such as small current tracking error, reduced total harmonic distortion (THD) index, strong robustness in the presence of parameters variation, and nonlinear load.

This paper proposes a novel control approach for single phase active power filter (APF) based on switched system theory, since the switching performance of APF. The switched model of APF is established by means of switching function. On this basis, the switched system error model is obtained. After that, a quadratic Lyapunov function is design to determine the switched control law. The switched control can make the switched system asymptotically stable and compensate the distorted current caused by the nonlinear load current. The effectiveness and rationality of the proposed approach is confirmed by the simulation result compared with the linear voltage control approach.

Abstract:
Active power filters (APFs) are dynamic power electronic devices that suppress harmonics and reactive power. To simplify the detection and extraction of traditional APF harmonics and reactive current, this paper proposes a direct source current control based on a three-phase three-wire shunt APF. The compensation principle and control method of the source current are analyzed systematically. The currents can be controlled without static errors by a proportional-integral (PI) controller in d-q rotating coordinates. Therefore, the compensation accuracy and dynamic performance of the system can be improved by the control strategy. Moreover, considering the grid voltage fluctuations, a droop regulator is proposed to address the impact of DC-link voltages on APF power losses and compensation performance. The regulator is combined with a traditional voltage outer loop PI control to achieve a comprehensive optimization between the power loss and compensation performance of the APF system. Finally, the inner current loop and the outer voltage loop form a double closed-loop cascade PI control structure to achieve the control effect of the APF. Simulation and experimental results verified the validity and feasibility of the APF control approach.

Abstract:
The active power filter (APF) is a popular electrical device to eliminate harmonics in power systems. The rational design and effective control of DC-link capacitor voltage are important for implementing APF functions. In this study, the influences from the DC-link voltage on the APF compensating current characteristic and compensation performance are analyzed, and the reason to maintain DC-link voltage at a minimum value is investigated. On this basis, a simplified minimum DC-link voltage control strategy for APF is proposed. Compared with the existing DC-link voltage control strategies, the minimum DC-link voltage value in proposed strategy is only determined by the grid voltage and modulation ratio, reducing the calculation burden and the implementation difficulty in application, avoiding the interference from external parameters on the compensation effect. Additionally, the reference DC-link voltage varies at different values according to the grid voltage and modulation ratio. A shunt APF prototype is established and the experimental results verify the correctness and effectiveness of the analysis and proposed strategy.

Abstract:
Soccer (football) practice can induce a limitation of ankle range of motion (ROM) that is a possible risk factor for injury and other negative consequences over time. The main objective of this research was to investigate the effects of soccer practice on ankle ROM throughout the entire period of a sports career of soccer players (SP). Furthermore, the relationship between ankle ROM and muscle strength in SP of different ages was studied. A total of 204 SP (range 6.7–45.1 years) and 87 controls (range: 7.5–45.2 years) matched for age, body mass index (BMI), and gender, were assessed. Ankle ROM in both plantar flexion (APF) and dorsiflexion (ADF) in addition to handgrip strength (HGS) were evaluated using an inclinometer and the Jamar hydraulic hand dynamometer, respectively. The comparison between SP and control groups showed a significant reduction in ankle ROM of both APF (26.3 ± 7.2° vs. 32.6 ± 7.4°; d = −0.90; p < 0.001) and ADF (95.5 ± 15.6° vs. 105.5 ± 15.8°; d = −0.66; p < 0.001). In SP, the results of the ANOVAs test indicate that age had a significant effect on ADF (F = 4.352, p = 0.038, partial eta-squared (ηp2) = 0.015) but not on APF (F = 0.430, p = 0.746, ηp2 = 0.001). Moreover, considering only the SP, a weak inverse correlation between ADF and HGS group ADF was found (rs = −0.27; p < 0.001). Factors such as the non-linear trend of growth in young SP could hinder the definition of the relationship between ankle ROM, age, and muscle strength. However, the appropriate consideration of age and muscle strength could facilitate the management of ankle ROM in PF of different ages.

Abstract:
The DC bus voltage stability control is one key technology to ensure that Active Power Filter (APF) operates stably. The external disturbances such as power grid and load fluctuation and the system parameters changing may affect the stability of APF DC bus voltage and the normal operation of APF. The mathematical model of DC bus voltage is established according to power balance principle and a DC bus voltage piecewise reaching law variable structure control algorithm is proposed to solve the above problem, and the design method is given. The simulation and experiment results proved that the proposed variable structure control algorithm can eliminate the chattering problem existing in traditional variable structure control effectively, is insensitive to system disturbance, and has good robustness and fast dynamic response speed and stable DC bus voltage with small fluctuation. The above advantages ensure the compensation effect of APF.

Abstract:
Several items need consideration when products are evaluated for use as transition agents. These are (1) efficacy of ryegrass removal [rate of ryegrass decline and appearance of turf during transition], (2) tolerance and performance of incoming bermudagrass and (3) application safety for next season’s repeat overseed operations. This test was designed to evaluate application safety for the next overseeding which occurs in the early fall. Therefore, AEF was applied in the summer to bermudagrass turf prior to overseed operations. Most responses of the perennial ryegrass (overseed) turf to previous treatments of AEF 130360 occurred immediately after overseeding, from mid-October to early November. AEF 130360 applied 2 weeks before overseeding caused a significant decrease in seedling vigor, percent plot ryegrass cover, and percent bermudagrass plot straw present. Both AEF treatments applied closest to overseeding (2 weeks prior) had the least amount of initial ryegrass, the greatest amount of green bermudagrass, and later in the season, the most amount of straw (dormant) bermudagrass. Differences in turfgrass quality were not significant due to treatments at any time throughout the test, and most treatments ranked higher than the control in overall quality. Under the conditions of this test, application of AEF 130360 at either 0.64 or 1.28 ounces/product/M made one month before actual oversseding did not cause detrimental effects to ryegrass emergence, ryegrass cover, turfgrass color or overall quality.

Abstract:
ABF -1 is a human class II bHLH transcription factor that is expressed predominantly in activated B cells and EBV immortalized cell lines. A portion of this study sought to characterize the homolog of ABF- l in Caenorhabditis e/egans. The nematode gene product, ceABF -1, is capable of forming heterodimers with E2A gene products and binding E box binding sites. HeLa cells transfected with ceABF-1 reveal that it is capable of blocking E2A mediated gene transcription. In order to maintain full repression capabilities, two conserved amino acid residues within helix I ofthe HLH domain are required. These results show a conserved mechanism of gene repression between invertebrates and vertebrates. This study also sought to analyze ABF-1 mediated regulation of both ld3 and cellular growth. Using a human ABF-1 stably transfected cell line, ID3 protein levels and transcript levels were shown to increase in response to overexpression of ABF-1 via western and northern blot, respectively. Flow cytometry analysis and Real-time PCR revealed that ABF-1 programs a slow down in the cell cycle, however this growth arrest is not mediated by ID3.

Abstract:
Toxoplasma gondii is an obligate intracellular protozoan parasite of animals and man. The asexual life cycle of Toxoplasma involves three very distinct, but tightly coordinated developmental stages. In nature, the sporozoite (contained within an oocyst) and bradyzoite (contained within a tissue cyst) initiate infection of the intermediate host, followed by rapid differentiation into the actively replicating tachyzoite. When countered by an effective host response, the tachyzoite differentiates back into the latent bradyzoite and this unique ability of Toxoplasma to interconvert between the replicating tachyzoite and the latent bradyzoite within a single host is the cause of life long infection. The transcriptional mechanisms controlling tachyzoite to bradyzoite differentiation and inter-conversion are largely unknown, however, a linkage between the parasite cell cycle and differentiation may underlie these developmental mechanisms. The recent discovery of a family of DNA binding proteins in Apicomplexa (ApiAP2) that are distantly related to the APETALA-2 (AP2) class of plant transcription factors has uncovered an important set of proteins (ApiAP2 factors) that have critical roles in regulating growth and developmental gene expression. Five Toxoplasma ApiAP2s were studied in this thesis project: AP2IX-9, AP2Ib-1, AP2IV-3 (Chapter 2); AP2IV-4 (Chapter 3); and AP2VI-1 (Chapter 4). A major conclusion of this work highlights a novel paradigm in our understanding of the cellular mechanisms regulating stage conversion in Toxoplasma. The study of AP2IX-9 and AP2IV-4 indicate development of the bradyzoite is governed by transcriptional repressors acting at two independent levels, one late in the cell cycle and a second governing the transition from the tachyzoite to the end-stage bradyzoite tissue cyst. The use of repressors to regulate development provides flexibility for the parasite to immediately respond to changing host conditions and modulate the competing needs of expansion and persistence. In addition, the study of AP2VI-1 demonstrates that Toxoplasma employs ApiAP2s that bind chromosome heterochromatin to establish a state of developmental competency AP2IX-9 (Chapter 2) has a unique transient expression profile restricted to early bradyzoite differentiation, and absent form both the tachyzoite and terminal tissue cyst. Disruption of the AP2IX-9 locus resulted in increased tissue cyst formation in vitro while conditional overexpression of AP2IX-9 significantly reduced tissue cyst formation, indicating AP2IX-9 operates as a repressor of bradyzoite development. Consistent with a role as a repressor, AP2IX-9 specifically inhibited the expression of bradyzoite mRNAs including BAG1, B-NTPase and LDH2, common markers for bradyzoite development. Two other ApiAP2s, AP2Ib-1 and AP2IV-3 have similar expression profiles as AP2IX-9 and are candidates for expanding our understanding of this repressor mechanisms regulating development. A number of mRNAs encoding ApiAP2 proteins are dynamically regulated during the tachyzoite cell cycle that also show unique profiles during bradyzoite development. AP2IV-4 (Chapter 3) and AP2VI-1 (Chapter 4) represent two of several cell cycle AP2s whose expression is associated with specific S-phase and mitotic transitions but illustrate divergent roles in regulating growth and development. The expression of AP2IV-4 is exclusive to the tachyzoite stage of development and peak expression coincides with mitosis of the cell cycle. Interestingly, deletion of AP2IV-4 results in the up-regulation of tissue cyst wall and bradyzoite surface antigens in the tachyzoite. The mis-expression of bradyzoite proteins in the tachyzoite indicate AP2IV-4, much like AP2IX-9, is stage specific transcriptional repressor active only late in the tachyzoite cell cycle, likely promoting continued replication of the tachyzoite stage. For AP2VI-1 (Chapter 4), an S phase exclusive factor, we have verified S phase expression using an HA fusion protein at the endogenous locus, determined its DNA binding specificity by EMSA, and developed a genetic model of conditional expression based on the small molecule, Shield-1. Attempts to genetically delete this factor were successful only in laboratory adapted strains of Toxoplasma, indicating AP2VI-1 has an essential function in the bradyzoite developmental pathway. Genome-wide binding (chromatin immunoprecipitation and microarray analysis (ChIP-chip)) regions of AP2VI-1 are indistinguishable from the recently published CenH3 regions (centromere marker) and similarly fall within the H3K9me2 and H3K9me3 methylation patterns (heterochromatin markers) that mark the centromere boundaries. AP2VI-1 was also detected in mature bradyzoites from in vitro or animal tissue cysts. This dual expression profile for AP2VI-1 may suggest this factor has a unique role in chromosome maintenance or stability during developmental transitions.

This thesis presents work that was done to improve the effectiveness of cleaning processes at an active pharmaceutical ingredient (API) manufacturing site that was in the phase of engineering trials and cleaning cycle development. Cleaning cycles executed on the site prior to the project were found to be inconsistent in cleaning the equipment to the desired specifications. Lack of repeatability of cleaning processes was hypothesized to be a resultant of inadequate process control and monitoring. Statistical Process Control (SPC) implemented using process automation was found to improve the success rate of cleaning processes significantly. SPC introduction required breaking down the cleaning operation into component steps, identifying critical process parameters (CPPs) and calculation of control limits using Shewhart Control Charts for these CPPs. Significant modifications were done to the automation controls for the recipe to ensure deviations from recipe are captured and appropriate actions are taken by the system or the operator to bring the process back in control. The success rate of cleaning processes improved from 38% to 72% post the implementation of Phase I of SPC with the newer non-conformances being associated to special external causes outside the control of the process. Real-time Multivariate Statistical Process Monitoring (RT-MSPM) was also introduced and piloted as a future opportunity for enhanced control and continuous quality improvement. Multivariate statistical process control eliminates the need to monitor multiple control charts (one for each variable) at the same time accounting for the correlations among process variables.

Abstract:
As altas exigências que impõe o mercado globalizado, a complexidade dos sistemas produtivos de manufatura atuais e os avanços na Tecnologia da Informação são fatos que resgatam a importância da Programação Detalhada da Produção para as empresas. A pesar de bastante consolidada e difundida, a abordagem clássica MRP / ERP não atende plenamente as necessidades em ambientes de produção intermitente. A Programação Detalhada da Produção com capacidade finita dos recursos, atualmente contemplada nos sistemas APS (Advanced Planning & Scheduling), constitui uma alternativa interessante para melhor cumprir prazos de entrega em ambientes com roteiros de produção complexos e produção make-to-order (MTO). O problema de pesquisa ora estudado contempla o ensino de modelos de Planejamento e Controle da Produção (PCP) em um ambiente de produção intermitente, com foco na Programação Detalhada da Produção e nos sistemas MRP e APS. Propõe-se um plano de ensino que busca apresentar e diferenciar essas abordagens. O plano contempla o uso de um caso didático A Fábrica de Skates. De uma forma lúdica, porém realista, o caso apresenta, nas suas cinco etapas, duas situações hipotéticas de uso de sistemas de programação. O primeiro, um MRP para planejamento da fábrica de skates e, no segundo, um APS utilizado pelo fornecedor de eixos. O plano foi aplicado pela primeira vez em uma turma de graduação do curso de Engenharia de Produção. Nesta dissertação, é apresentada uma descrição detalhada do caso didático, junto ao plano de ensino. A pesquisa verificou, mediante análise das atividades do caso e de um questionário de avaliação, a utilidade dos recursos elaborados, como também que as estratégias aplicadas ajudaram na aprendizagem. Nesta primeira aplicação, constatou-se também que a alta carga de trabalho dos alunos no semestre e o pouco peso dado à nota final do caso didático foram fatores que inibiram melhores resultados. Para futuras aplicações, o caso didático pode ser aprimorado: novas etapas contemplando outros assuntos importantes para a disciplina PCP e análise de alternativas para substituição dos softwares empregados são exemplos de melhorias.
The high standard of competition in global market, the complexity of current manufacturing systems and the advances in Information Technology highlight the importance of the detailed production scheduling. Although classical approaches such as MRP perform this function quite well in different situations, these systems do not perform well in make-to-order (MTO) production systems. The finite capacity scheduling currently embedded within the software called APS (Advanced Planning & Scheduling) is a more interesting approach to achieve better performance in meeting due dates in production environments with complex routings and MTO strategy. Thus, the problem addressed in this study concerns the teaching of Production Planning and Control (PPC) models for intermittent production, with focus on the detailed production scheduling using MRP and APS approaches. In order to that, a teaching plan is proposed to present and differentiate these approaches. It includes the use of an educational case study named \"The Skateboard Factory\". In a playful but realistic way, the case presents, in its five stages, two hypothetical situations of use of scheduling systems. First, an MRP approach for planning in the skateboard factory, and second, one APS approach used by the truck supplier. The teaching plan was first applied to an undergraduate degree Production Engineering program. In this dissertation, a detailed description of the educational case study, along with the teaching plan, is provided. The results achieved in the case study and the students evaluation attest to the usefulness of the resources designed, and also that the strategies applied really improved the learning process. In this first application, it was also observed that high workload and the little weight in the final grade of the case study inhibit better results. In future applications, the case can be enhanced to include new stages on other important issues of the PPC discipline and the replacement of the software used.

Abstract:
Abstract The aryloxyphenoxypropionate (APP) herbicides are graminicides with excellent control of many grass weed species, including weedy rice (Oryza sativa L.). These herbicides block fatty acid biosynthesis by inhibition of the enzyme acetyl-CoA carboxylase (ACCase) and cause death of the plant. Through induced mutation of rice seeds with gamma-rays, rice lines resistant to APP have been developed. Plant dose-response assays confirmed resistance to the APP herbicides quizalofop-p-ethyl and haloxyfop-p-methyl. The carboxyl-transferase (CT) domain fragments of ACCase from the resistant line and the susceptible control were sequenced and compared. A point mutation was detected in the amino acid position 2027. Results indicated that resistance to APP herbicides is a consequence of an altered ACCase enzyme that confers resistance. APP-resistant rice provides an option to improve the efficiency of weed management in rice crops.
