Two degree-of-freedom spacecraft attitude controller

Two degree-of-freedom controller is designed together with its governing equations for a spacecraft pitch attitude control. The attitude controller incorporates the Active Force Control (AFC) technique into the conventional Proportional-Derivative (PD) controller based spacecraft pitch attitude loop. The PD-AFC attitude controller is then employed to enhance the attitude pointing of the Combined Energy and Attitude Control System (CEACS). Numerical treatments are performed to validate the effectiveness of AFC, whereby the CEACS attitude performance is analysed from its accuracy point of view. The results show that the PD-AFC attitude control performance is superiorly better than that of the solely conventional PD type

Heavy Duty Vehicle Fuel Consumption Modelling Using Artificial Neural Networks.

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.In this paper an artificial neural network (ANN) approach to modelling fuel consumption of heavy duty vehicles is presented. The proposed method uses easy accessible data collected via CAN bus of the truck. As a benchmark a conventional method, which is based on polynomial regression model, is used. The fuel consumption is measured in two different tests, performed by using a unique test bench to apply the load to the engine. Firstly, a transient state test was performed, in order to evaluate the polynomial regression and 25 ANN models with different parameters. Based on the results, the best ANN model was chosen. Then, validation test was conducted using real duty cycle loads for model comparison. The neural network model outperformed the conventional method and represents fuel consumption of the engine operating in transient states significantly better. The presented method can be applied in order to reduce fuel consumption in utility vehicles delivering accurate fuel economy model of truck engines, in particular in low engine speed and torque range

Inhibition of Xanthomonas fragariae, Causative Agent of Angular Leaf Spot of Strawberry, through Iron Deprivation.

In commercial production settings, few options exist to prevent or treat angular leaf spot (ALS) of strawberry, a disease of economic importance and caused by the bacterial pathogen Xanthomonas fragariae. In the process of isolating and identifying X. fragariae bacteria from symptomatic plants, we observed growth inhibition of X. fragariae by bacterial isolates from the same leaf macerates. Identified as species of Pseudomonas and Rhizobium, these isolates were confirmed to suppress growth of X. fragariae in agar overlay plates and in microtiter plate cultures, as did our reference strain Pseudomonas putida KT2440. Screening of a transposon mutant library of KT2440 revealed that disruption of the biosynthetic pathway for the siderophore pyoverdine resulted in complete loss of X. fragariae antagonism, suggesting iron competition as a mode of action. Antagonism could be replicated on plate and in culture by addition of purified pyoverdine or by addition of the chelating agents tannic acid and dipyridyl, while supplementing the medium with iron negated the inhibitory effects of pyoverdine, tannic acid and dipyridyl. When co-inoculated with tannic acid onto strawberry plants, X. fragariae's ability to cause foliar symptoms was greatly reduced, suggesting a possible opportunity for iron-based management of ALS. We discuss our findings in the context of 'nutritional immunity,' the idea that plant hosts restrict pathogen access to iron, either directly, or indirectly through their associated microbiota

Young people's sexual experience

The rise in teenage pregnancy and young people's vulnerability to HIV have been a serious problem. This paper is intended to confront this statement based on its structural concepts (adolescence, youth, teenage pregnancy, and vulnerability) and by a non-exhaustive review of the relevant literature. The current paper discusses the ideas of youth and adolescence to approach the sexuality of young people and adolescents from the perspective of inequalities between different social groups and their access to health and resources for the prevention of diseases like HIV/AIDS as well as contraception. There are multiple paths leading young people to having unprotected sexual relations, and the numbers that surface on pregnancy, STDs, and HIV infection are doubtless lower than the real figures. The data presented herein indicate that the safe-sex approach is still necessary among youth, requiring efforts to produce creative strategies that make sense in different socio-cultural contexts in which young people experience sex.O aumento da gravidez na adolescência e da vulnerabilidade dos jovens ao HIV tem sido um grave problema. Pretende-se problematizar esta assertiva pela análise dos termos que a estrutura ­ adolescência, juventude, gravidez na adolescência e vulnerabilidade ­ e pela revisão não exaustiva da literatura referente ao tema. Neste artigo discutem-se as idéias de juventude e adolescência para abordar a sexualidade dos jovens e adolescentes sob a perspectiva das desigualdades entre os diferentes grupos sociais e seu acesso à saúde e aos recursos para prevenção de doenças como HIV/ AIDS e à contracepção. São múltiplos os caminhos que levam um jovem a ter relações sexuais desprotegidas, e os números que vêm à tona sobre a gravidez, DST ou sobre a infecção pelo HIV sem dúvida são menores do que os números reais. Os dados apresentados ao longo do texto indicam que a abordagem do sexo seguro entre jovens continua sendo necessária, exigindo esforços de produção de estratégias criativas que façam sentido nos diferentes contextos sócio-culturais nos quais os jovens experimentam o sexo.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUniversidade de São Paulo Faculdade de Medicina de Ribeirão PretoUNIFESP, EPMSciEL

Global Symposium on Women in Fisheries

All over the world, women contribute in multiple ways to the production, processing, marketing and management of fish and other living aquatic resources. The first ever Global Symposium on Women in Fisheries, held in Kaohsiung, Taiwan on 29 November 2001 generated the present collection of papers on women in fisheries. The reader of this volume will find in it a wealth of information, albeit in a very heterogeneous form, that the authors have had to draw from many different sources. Some are primary research studies whereas most are historical reviews from first hand experience of the authors or derived from other written materials, often contained in reports of fisheries development projects, newspapers and source materials well outside the fish sectors.Women, Participation, Sustainability, Poverty, Fisheries, Development projects, Fishery technology

International Symposium on Women in Asian Fisheries

International Symposium on Women in Asian Fisheries presents a record of the 1998 symposium. The fisheries sector has unique problems related to women, which have to be addressed not only from a technical standpoint but also from a social one. The symposium is aimed at stimulating discussion and promoting well-planned research and development activities in this area.Role of Women, Fisheries, Socioeconomics, Indochina, Mekong River, Philippines, Malaysia, Taiwan, India, Bangladesh, Asia,
