Hydraulic power and control system
2020
Abstract In recent years, there has been worldwide interest in the improvement of the mobility of people with lower-limb amputation. Despite significant developments in new technologies during the last decade, commercial below-knee and above-knee prostheses are still energetically passive devices. However, many locomotive functions, like walking up stairs and slopes, need significant power in the knee and ankle joints. The additional power for doing previously mentioned activities needs to be achieved by means of external energy sources, which should be integral prosthetic components. In this chapter the design and development of the hydraulic power and control system are described.
Inferences are just folk psychology
2004
To speak of “inferences,” “interpretations,” and so forth is just folk psychology. It creates new homunculi, and it is also implausible from a purely phenomenological perspective. Phenomenal volition must be described in the conceptual framework of an empirically plausible theory of mental representation. It is a non sequitur to conclude from dissociability that the functional properties determining phenomenal volition never make a causal contribution. I have offered an alternative interpretation of some of Dan Wegner’s most relevant data elsewhere (Metzinger 2003, p. 506ff), and will confine myself to three conceptual points here. Wegner’s project could be further strengthened by eliminati…
“We want financial accountability”: deconstructing tensions of community participation in CHPS, Ghana
2016
ABSTRACTThis article reports on the ways and factors that facilitate or constrain community participation in the Community-based Health Planning and Services (CHPS) programme in Nsanfo, a village in Central Region of Ghana. We found that the community made an important step through mobilising the necessary resources in establishing the CHPS compound, which has resulted in improved access to health care. Yet maintaining the facility did not matter most to community members, owing chiefly to unmet demands for financial accountability pertaining to the running of the programme. Failure to clearly identify various actors and their roles potentially explains this state of affairs.
A Comprehensive Look at the Real-Life Performance of Moving Average Trading Strategies
2015
Despite the enormous current interest in market timing and a series of publications in academic journals, there is still lack of comprehensive research on the evaluation of the profitability of trading rules using methods that are free from the data-snooping bias. In this paper we utilize the longest historical dataset that spans 155 years and extend previous studies on the performance of moving average trading rules in a number of important ways. Among other things, we investigate whether overweighting the recent prices improves the performance of timing rules; whether there is a single optimal lookback period in each trading rule; and how accurately the trading rules identify the bullish …
Gènere i traducció en català. Bases arqueològiques per a un estat de la qüestió
2011
En els darrers vint-i-cinc anys l’interès pels estudis de traducció i la relació amb el gènere ha propiciat una recerca abundant i diversa. Aquest article mira d’oferir una visió panoràmica sobre la intersecció de la traducció i els estudis de gènere en el context de la llengua catalana, un punt de partida per a recerques futures. D’una banda, donem notícia dels principals treballs, panoràmics i específics, que se centren en la recuperació de traductores catalanes i els seus escrits. De l’altra, repassem les teories que han plantejat la intersecció gènere i traducció en català.
The Paper Industry in Germany, 1800–2000
2012
Germany is the biggest paper exporter in the world, the biggest paper producer in Europe and the fourth biggest producer in the world. It is also the biggest market in Europe and a major export market for European pulp producers. However, only three German pulp and paper companies made it to the top 100 list of the industry in 2010 and none made it into the top 50 (PPI 2011). This article describes the development of the German industry from the beginning of the nineteenth century to the present in order to explain the factors contributing to this unusual state of affairs in a country which, during the second Industrial Revolution, created major players in the new global oligopolies in chem…
Blockchain Tokens From the Perspective of German Civil Law: An Updated View
2020
Tokens are increasingly being generated on the basis of blockchain technology, which are intended to embody certain rights and obligations as cryptographically secured electronic coupons or digital coupons or vouchers . This paper provides an overview of the current state of affairs and the legal discussion of recent years and examines the extent to which blockchain tokens can be included under the existing German civil law framework of the BGB (German Civil Code). The key question is how goods can be legally represented ("tokenised") digitally and effectively by tokens instead of in documents. There are several approaches to make tokens marketable. Among them are also those that let the "r…
Difficulties in mobility among elderly people and their association with socioeconomic factors, dwelling environment and use of services.
1995
The purpose of this study was to clarify the extent to which elderly people have difficulties in mobility, and determine their association with socioeconomic factors, dwelling environment and use of services. The study groups were composed of two random samples of 800 persons aged 65–74 and 75–84, respectively. In all, 1224 non- institutionalized persons (80%) were interviewed at home. The respondents were asked to assess their ability to get about the house, negotiate stairs and walk outdoors, as well as manage certain physical exercise tasks. Difficulties in getting about outdoors were found most frequently among the women in the older age group (52% reported difficulties), and least freq…
The maximisation of the rate of financial profit
1991
On the traditional micro-economic theory, firms are supposed to maximise pure profit. We study what happened when we take into consideration shareholders and the financial profit remunerating the financial capital. We show that it is necessary to surrender the financial profit maximisation to use the rate of financial profit maximisation. The cases of concurrence with fix coefficient of capital, monopoly with fix coefficient of capital, monopoly with variable coefficient of capital are studied, and the role of contraints of rentability are treated. The solutions given by the profit maximisation and by the rate of profitmaximisation are compared. We conclude to a reduction of the volume of i…
Adhesive root hairs facilitate Posidonia oceanica seedling settlement on rocky substrates
2015
Posidonia oceanica, the dominant Mediterranean seagrass, has been historically described as a species typically growing on mobile substrates whose development requires precursor communities. During more than 10 years of direct observations, we noticed that P. oceanica seedlings were often firmly anchored to rocky reefs, even at exposed sites. Thus, we analysed the ultrastructural features of seedling root systems to identify specific traits that may represent adaptations for early seedling anchorage on rocky bottoms. Subapical sections of adventitious roots were obtained from 2-3 months old specimens collected in the field and were observed at SEM revealing an extensive coverage of adhesive…
