Some analytical results concerning PI controller tuning based on integrator plus time delay models are worked out and presented. A method for obtaining PI controller parameters, Kp = α/kτ , and, Ti = β ,which ensures a given prescribed maximum time delay error, dτmax, to time delay, τ , ratio parameter δ = dτmax/τ , is presented. The corner stone in this method, is a method product parameter, c̄ = αβ.Analytical relations between the PI controller parameters, Ti, and, Kp, and the time delay error parameter, δ, is presented, and we propose the setting, β= c̄/a (δ + 1), and, α = a/δ+1, which gives, Ti = c̄/a (δ + 1)τ ,and, Kp = a(δ+1)kτ , where the parameter, a, is constant in the method product parameter, c̄ = αβ. It also turns out that the integral time, Ti, is linear in, δ, and the proportional gain, Kp, inversely proportional to, δ + 1. For the original Ziegler Nichols (ZN) method this parameter is approximately, c̄ = 2:38, and the presented method may e.g., be used to obtain new modified ZN parameters with increased robustness margins, also documented in the paper.© 2010 Norwegian Society of Automatic Control.

This paper demonstrates a number of PI controller tuning methods being used to tune a temperature controller for a real air heater. Indices expressing setpoint tracking and disturbance compensation andstability margin (robustness) are calculated. From these indices and a personal impression about how quick a method is to deliver the tuning result and how simple it is to use, a winning method is identified. © 2010 Norwegian Society of Automatic Control.

In recent writings the concept of absence has been used to question the reach of phenomenological accounts of the human-world relation from a deconstructionist perspective. This article argues that absence is rooted in the corporeal embedded ness of human beings in the world that surrounds them. This is the case although absences refer to entities that are not present. Discussing the absence-presence relation, it is made clear that the simultaneity of absence and presence is not paradoxical, because the absence of presence and the presence of absence refer to different entities. Contrary to the connotation of absence with Derrida, the spectral and haunting, absences are experienced in a wide variety of practices that are both extraordinary and mundane. A detailed investigation into the processes in which absences are experienced then shows how an experience of absence comes into being and what affects the power of the experience. The article argues that the experience of absence is stronger when it refers to practices, emotions and corporal attachments that have been deeply ingrained into those who experience the absence. Since materiality, embodiment and (the lack of) resistance play a crucial role in the actual experience of absences, the conceptualization of absence should reflect these qualities. It is precisely because absence is rooted in processual corporality that absence can unfold such disturbing power. Those who experience something as absent have to fill the void that they experience with their own emotions, they have to bridge the emptiness that threatens their established expectations and practices. Accordingly, absence is presented as a phenomenological grounded concept that gains its epistemological and experiential quality through its connection to the corporal body, its senses and emotions, and the world around it. © The Author(s) 2013.

The relevance of chemical communication to mammalian conservation is not often the focus of scientific investigation. Our review identifies and discusses ten key areas in which the study of chemical communication aids conservation behaviour. Articles (n=140) were revealed, most were concerned with population monitoring (22.50%), reducing human-wildlife conflicts (18.93), influencing habitat selection (18.57%), increasing welfare of captive animals (12.86%), encouraging captive breeding (12.86%), reducing predation (5.71%), and increasing the success of release programmes (5.00%). Few articles (<4%) were found relating olfactory studies to health status of wild populations, reducing hybridization or as indication of pollution. A growing number of articles are addressing how olfactory studies may aid conservation, but more rigorous experimental testing and manipulations are required. The vast majority of studies linking olfaction with conservation involved the population monitoring of wild carnivores. We suggest that animal behavioural studies and manipulations of chemical communication can have significant impacts on conservation in these areas, which should be further developed to generate practical applications. Areas of future study include chemical communication of aquatic mammalian species, the transfer of olfactory cues under water, and the identification of genetic markers that may link 'personality' with olfactory responses. Linking olfactory studies to fitness, either on an individual or population scale, particularly in a wider ecological context is more likely to increase conservation value. Animal translocations and reintroduction programmes may offer a means to do this and could be an important area to direct future studies. © 2011 Elsevier Ltd.

Environmental settings seem to influence the activity patterns of children in neighbourhoods and schoolyards, the latter being an important arena to promote physical activity (PA) in school children. New technology has made it possible to describe free-living PA in interaction with the environment. Aims of study: This study focused on how schoolyard environments influenced the activity patterns and intensity levels in 14-year-old children and whether PA levels in adolescents complied with official recommendations. Another objective was to introduce methodology of using a mobile global positioning system (GPS) device with synchronous heart rate (HR) recordings as a proxy for PA level and a geographical information system (GIS) for spatial analyses. The sample constituted of 81 children (aged 14 years) from two schools. Movement patterns and activity levels were recorded during lunch break applying a GPS Garmin Forerunner 305 with combined HR monitoring and analysed in a GIS by an overlaid grid and kriging interpolation. Spatial data from GPS recordings showed particular movement patterns in the schoolyards. Low activity levels (mean HR < 120 bpm) dominated in both schools with no gender differences. Activities located to a handball goal area showed the highest monitored HR (>160 bpm) with higher intensity in girls than in boys. Movement patterns and PA generated in GIS for visualisation and analysis enabled direct and realistic description of utilising of schoolyard facilities and activity levels. Linking GPS data and PA levels to spatial structures made it possible to visualise the environmental interaction with PA and which environments promoted low or high PA.

A novel experimental method - here denoted the Good Gain method { for tuning PI controllers is proposed. The method can be regarded as an alternative to the famous Ziegler-Nichols' Ultimate Gain method. The approach taken resembles the Ziegler-Nichols' method as it is based on experiments with the closed loop system with proportional control. However, the method does not require severe process upset during the tuning like sustained oscillations. Only well-damped responses are assumed. Furthermore, in the present study it is demonstrated that the approach typically gives better stability robustness comparing with the Ziegler-Nichols' method. The method is relatively simple to use which is beneficial for the user. A theoretical rationale based on second order dynamics is given. © 2013 Norwegian Society of Automatic Control.

A CO2 capture process based on MEA absorption has been simulated with Aspen HYSYS and Aspen Plus. Both rate-based simulations and simulations with specified Murphree efficiencies have been performed. The differences between the equilibrium models and between Aspen HYSYS and Aspen Plus were small. The removal efficiency was calculated to be lower and the temperature profiles were slightly different in the rate-based calculations. The simulations were close to equivalent if the aim is to calculate CO2 removal efficiency as a function of circulation rate, number of column stages and inlet temperature. © 2012 The Authors.

Background: International studies have generally defined nursing as a female-dominated occupation. The almost absence of male nurses seems universal, except as a privileged minority occupying positions within nursing specialties ('islands of masculinity'). Nursing is associated with relatively low status owing to gender and income, and is also influenced by cultural perceptions of social status, the nature of the work and sexuality. Objective: This study aims to describe and analyse how gender and cultural perceptions influenced the development of nursing in Mauritius. This paper examines why nursing in Mauritius became gendered in different ways due to the impact of gender equivalence in the work force, the gendered segregation in clinical practice and the absence of caring feminisation in nursing. Design and setting: This qualitative study is based on in-depth, semi-structured interviews and convenience sampling. The sample includes nurses working at five hospitals. They all come from the central and southern part of Mauritius. The data were collected over a five-month period during 2006. Participants: Individual qualitative interviews were conducted with 47 nurses, both men (27) and women (20), of different grades, ages, religions and ethnic backgrounds. Results: Nursing practice is gender segregated, influenced and supported by cultural traditions and perceptions of gender relations, sexuality and touch in nursing. However, the professional identity and role is considered non-gendered, implied by the title of 'nursing officer' and the presence of male nurses who constitute almost 50 percent of the work force. Male nurses do not face similar barriers deterring them from entering nursing profession. Nursing did not develop the image of women's work and a low status job in Mauritius. Conclusions: The nursing profession in Mauritius has been shaped by a different 'history of origin', social, cultural and societal conditions on the basis of the absence of gender imbalance in the work force and caring feminisation in nursing. Moreover, the increase of men's presence in nursing influenced its name, status and perception, shifting nursing into a masculine sphere with advantageous impacts on nursing. © 2013 Elsevier Ltd.

Microcystins (MC) are potent cyclic heptapeptide toxins that are produced by many cyanobacterial genera e.g. Planktothrix, Microcystis. Human exposure occurs primarily during bloom events, via drinking or contact with contaminated water, food or aerosols. While food exposure and corresponding health effects are rare, exposure to high MC concentrations via drinking water has resulted in morbidity and mortality. However, little is known about the level of MC exposure in humans when sub-chronically or chronically exposed via aerosols or drinking water as is the case in populations living within close proximity to water bodies experiencing toxic blooms, e.g. the population of San Roque dam, Argentina. To accurately determine human exposure, an in-depth understanding of the physical and physiological events governing toxic bloom formation and regulating MC production is critical. In this study we will (1) undertake a series of in-lake mesocosm studies to explore thresholds and triggers of up-regulation of MC. Samples will be analyzed using a suite of sensitive molecular (QPCR, RT-QPCR, metagenome analysis), immunological and chemical techniques in concert with physical and geochemical measurements , (2) undertake a series of field-experiments, incl. the San Roque location, in which we will monitor a range of physiochemical parameters, and in-lake and aerosolized MC levels, and (3) use a hydrodynamic model to define water movement coupled to an ecological model enabling predictions of toxins in aerosols and water. Laboratory techniques and questionnaires specifically developed to allow monitoring of human toxin exposure, will be used to assess health impacts of toxins and aerosols. The consortium represents aquatic ecologists, microbiologist, molecular biologist, modelers, toxicologists and medical staff. Exchanging staff will ensure increased understanding and implementation of technologies and lead to improved human risk assessment.
