Characterisation of ozone levels and associated NMVOC emissions in Spain:

In Europe, for the last decades, multiple efforts have been made to regulate and reduce air pollution. Despite the overall reduction trends in emissions, air quality remains poor in many areas, where 99% of the urban population is exposed to tropospheric ozone (referred to as O3 from here on) concentrations above the World Health Organization Air Quality Guideline value [1]. O3 is a secondary atmospheric pollutant with complex mechanisms of formation and reaction processes, transport, and deposition. The nonlinear nature of its production is one of the main challenges in controlling ozone levels [2]. Spain shows several areas with O3 problems. Regarding the target value of O3 for health protection, out of the 127 areas where it was evaluated in 2019, 34 of them show values above the target value, 81 values between the target value and the long-term target value, and the remaining 12 are below the long-term objective. These results have not substantially improved since 2011 and are constant since 2016 [3]. The Spanish Ministry is currently designing a strategy to tackle the O3 problem in Spain. In this context, air quality modelling systems become an important complementary tool on which to quantify and evaluate the impact of such air quality plans. Two major directly emitted precursors drive O3 formation: nitrogen oxides (NOx) (which includes both nitrogen monoxide, NO, and nitrogen dioxide, NO2) and non-methane volatile organic compounds (NMVOC), so in order to assess O3, a correct characterization of its precursors is required. This work focuses on producing a speciated NMVOC inventory for anthropogenic emissions in Spain to support more effective control strategies. The type of NMVOCs emitted varies widely from one source to another, differing substantially by, e.g. fuel, technology, and others. The significant differences between NMVOC species lead to differences in atmospheric chemical reactivity and result in differences in their influence on the formation of ozone. Therefore, speciated NMVOCs emissions and the estimation of ozone formation potential (OFP) are essential to the reactivity-based control approach

The use of genes for performance enhancement: doping or therapy?

Recent biotechnological advances have permitted the manipulation of genetic sequences to treat several diseases in a process called gene therapy. However, the advance of gene therapy has opened the door to the possibility of using genetic manipulation (GM) to enhance athletic performance. In such ‘gene doping’, exogenous genetic sequences are inserted into a specific tissue, altering cellular gene activity or leading to the expression of a protein product. The exogenous genes most likely to be utilized for gene doping include erythropoietin (EPO), vascular endothelial growth factor (VEGF), insulin-like growth factor type 1 (IGF-1), myostatin antagonists, and endorphin. However, many other genes could also be used, such as those involved in glucose metabolic pathways. Because gene doping would be very difficult to detect, it is inherently very attractive for those involved in sports who are prepared to cheat. Moreover, the field of gene therapy is constantly and rapidly progressing, and this is likely to generate many new possibilities for gene doping. Thus, as part of the general fight against all forms of doping, it will be necessary to develop and continually improve means of detecting exogenous gene sequences (or their products) in athletes. Nevertheless, some bioethicists have argued for a liberal approach to gene doping

Estresse articular no membro superior durante marcha assistida por andador em pacientes pós-cirúrgicos

BACKGROUND: A walker is a common device prescribed for ambulatory assistance for individuals with balance difficulties or to reduce lower extremity demands following injury or surgery. The long-term use of a walker imposes significant demands on the patient's upper extremities that may lead to increased risk for development of secondary conditions such as wrist, elbow or shoulder pain. OBJECTIVE: To describe the joint kinematics, forces and moments of the wrist, elbow and shoulder in a sample of twenty patients that were using a walker as a result of total joint surgery of the hips and knees. METHODS: Three-dimensional upper extremity kinematics were recorded using a motion capture system synchronized with forces and torques transmitted through a walker instrumented with force transducers in the handles. RESULTS: Compressive forces were found to be nearly 20% of the body weight at each of the upper extremity joints, both surgical and non-surgical sides, being the greatest force at the wrist and decreasing proximally. Compression forces were greater in the non-surgical side limb at the wrist and at the elbow. CONCLUSION: Our findings indicated that loads on upper extremity joints associated with the use of a walker for assisted ambulation are high and further studies are needed to address the cause-effect relationship between the actual joint loading and the development of secondary musculoskeletal upper extremity complaints in more frail patients.CONTEXTUALIZAÇÃO: Um andador é um dispositivo frequentemente prescrito para auxiliar a marcha de indivíduos com dificuldades de equilíbrio ou para reduzir demandas à extremidade inferior após cirurgia ou lesão. O uso prolongado de um andador impõe significante demanda para a extremidade superior do paciente, o que pode levar a um risco aumentado de desenvolver condições secundárias, como dor no punho, cotovelo e ombro. OBJETIVO: Descrever a cinemática articular, forças e momentos do punho, cotovelo e ombro de uma amostra de 20 pacientes que faziam uso de um andador após cirurgia de substituição articular do joelho ou quadril. MÉTODOS: A cinemática tridimensional foi registrada usando um sistema de captura de movimento sincronizado com o registro de transdutores de força, que mediam a força transmitida através do andador. RESULTADOS: Este estudo revelou forças de até 20% do peso corporal nos transdutores, com forças compressivas maiores do lado do membro inferior não operado, no punho e no cotovelo. CONCLUSÃO: Os achados indicam que demandas no membro superior associadas ao uso de andador como dispositivo auxiliar da marcha são grandes, e mais estudos são necessários para averiguar relações de causa-efeito entre as reais sobrecargas articulares e o desenvolvimento de queixas musculoesqueléticas no membro de pacientes em condições de debilidade

A DIN Spec 91345 RAMI 4.0 Compliant Data Pipelining Model: An Approach to Support Data Understanding and Data Acquisition in Smart Manufacturing Environments

Today, data scientists in the manufacturing domain are confronted with various communication standards, protocols and technologies to save and transfer various kinds of data. These circumstances makes it hard to understand, find, access and extract data needed for use case depended applications. One solution could be a data pipelining approach enforced by a semantic model which describes smart manufacturing assets itself and the access to their data along their life-cycle. Many research contributions in smart manufacturing already came out with with reference architectures like the RAMI 4.0 or standards for meta data description or asset classification. Our research builds upon these outcomes and introduces a semantic model based DIN Spec 91345 (RAMI 4.0) compliant data pipelining approach with the smart manufacturing domain as exemplary use case. This paper has a focus on the developed semantic model used to enable an easy data exploration, finding, access and extraction of data, compatible with various used communication standards, protocols and technologies used to save and transfer data.publishersversionpublishe

Cooking behaviours: a user observation study to understand energy use and motivate savings

Electric cookers are one of the highest energy consuming domestic appliances, and there are several aspects that can influence the amount of energy used when preparing a meal. Appliance characteristics are shown to influence consumption, but human factors play an important role in the overall electricity usage. A user observation study was conducted among uni-versity students to understand how they use electric cookers. They were asked to perform a specific cooking task, and the elec-tricity usage was measured. Participants’ behaviours were analysed and compared with a set of energy saving techniques. Ap-pliance characteristics that influenced how students use energy were also investigated. The results show that users performed the task in several different ways, presenting diverse energy consumption, the average being 3 times above the necessary to complete the task. This information is now informing the design of interventions to motivate people to change their behaviours whilst cooking

Understanding cooking behaviours to design energy saving interventions

People's behaviours play an important role in energy consumption, especially whilst dealing with high consumption, highly interactive appliances such as cookers. In a user observation study conducted among university students, participants were asked to perform a simple cooking task. Their behaviours were analysed and compared with a set of recommended practices. The electricity usage and time to complete the activity were also measured. The results show that participants performed in several different ways, presenting diverse energy usage. The determinants of these behaviours were also collected, and will help to inform the design of interventions to motivate people to change their behaviours whilst cooking

Evaluation of the behaviour of reinforced concrete beams repaired with glass fibre reinforced polymer (GFRP) using a damage variable

The use of fibre reinforced polymers (FRP) for increasing the strength of RC structures became a usual method. FRP presents easy application and demands low space and provide significant strength increase. Usually, the decision for FRP use is made in terms of applied loads and deflections. However, such quantities can vary significantly depending on the characteristics of the structural element e.g. span, effective depth and concrete resistance. Therefore, this paper aims to present an alternative control variable to analyse the behaviour of RC beams repaired with glass fibre reinforced polymer (GFRP), called damage. Such damage variable accounts for concrete cracking and it was experimentally measured before and after the application of GFRP. Note that the application of GFRP increased the ultimate load for all repaired beams. The damage values of such beams also increased when collapse was reached. Furthermore, it was observed that the collapse mechanism shifted to shear and did not occurred the failure of the GFRP

Cooking behaviours: understanding energy use to design persuasive applications

Electric cookers and kettles are often high electricity consumers amongst household appliances. Cooking requires several interactions with these appliances, and furthermore people’s behaviours play an important role in the energy consumption. This research is seeking to understand people’s behaviours whilst cooking and also identify the determinants of these behaviours. Energy monitoring, video recording and semi-structured questionnaires were used to gather this information. This knowledge will inform the development of an intervention aiming at reducing energy expenditure

Using social network games to reduce energy consumption

This research is investigating the potential role of online social network based life simulation computer games as a persuasive tool for encouraging users to reduce their domestic energy consumption. Games such as ‘Farmville’ which runs on the Facebook platform have attracted millions of users worldwide who create simple virtual worlds where they interact with others and carry out everyday activities to earn tokens to spend within the game. Applying a User Centred Design (UCD) and in particular persona based design approach, this research is investigating why users find these games so enticing, the characteristics of those who play them, and the context in which they are played. Through an iterative UCD process, a life simulation game will be designed with users who represent a number of key ‘gamer personas’ in order to research how this sort of game could be used to encourage domestic energy saving behaviours
