Le médicament homéopathique dans l'histoire du médicament, Co construction, confrontation, coopération. Histoire, Transmission, Représentation

2007

The dynamics of this thesis resides in the search for the breach between the historical positioning (in relation to scientific fact itself) of homeopathic medication in the history of medical sciences, and the representation made of it in the past and present. By distinguishing what may be at stake, we are led to identify the positioning and impact of the mode of transmitting scientific fact as lacking a historical link to the history of medical sciences, notably medication. Our research hypothesis thus postulates that the transmission mode is at the source of discrepancies in representation. The links between context breakthroughs, such as the role of influences, are just parameters that, …

On the effects of transmit power control on the energy consumption of WiFi network cards

2009

Transmit power control has been largely proposed as a solution to improve the performance of packet radio systems in terms of increased throughput, spatial reuse and battery lifetime for mobile terminals. However, the benefits of transmit power control schemes on these different performance figures may strongly depend on the employed PHY technology and channel access mechanism. In this paper, we focus on the effects of power control on the energy consumption of WiFi network cards. By means of several experimental tests carried out under different operation conditions and modulation schemes, we try to justify why the reduction of the transmission power has a marginal effect on the overall en…

Energy efficient model for biogas production in farm scale

2011

Energy efficient solutions for six farm biogas production was found by calculating mass and energy balance in different scenarios. Raw materials in biogas production were cow manure and grass silage that were produced in these farms. There were calculated mass and energy balances on average for one year biogas prouduction that consisted of grass silage production, raw material transportation and biogas production in the biogas plant. In addition, direct greenhouse gases from biogas production were estimated. The direct mass and energy flows were calculated. It turned out that one input energy unit can produce 5.0 to 5.5 energy units as heat and electricity. Biogas reactor consumed heat from…

Trynitarny wymiar komunijnej struktury Kościoła w ujęciu Josepha Ratzingera - Benedykta XVI

2015

The Church is a community that has its origin in God. He himself, being the relationship of Three Persons since the beginning of the world calls people to a relationship with him. This community has its fulfillment in the community initiated by the apostles, who following in the mission of Christ are preaching salvation in the name of the Father, the Son and the Holy Spirit. The church, besides its spiritual, divine origin also has a temporal dimension expressed in its structure of the local Churches, hierarchy or the implemented mission. Even what in Church is most external and human has its trinitarian representation. The whole Church with all its elements is immersed in the trinitarian r…

Economic and Life Cycle Analysis of Passive and Active Monitoring of Ozone for Forest Protection

2021

At forest sites, phytotoxic tropospheric ozone (O3) can be monitored with continuously operating, active monitors (AM) or passive, cumulative samplers (PM). For the first time, we present evidence that the sustainability of active monitoring is better than that of passive sensors, as the environmental, economic, and social costs are usually lower in the former than in the latter. By using data collected in the field, environmental, social, and economic costs were analyzed. The study considered monitoring sites at three distances from a control station in Italy (30, 400, and 750 km), two forest types (deciduous and Mediterranean evergreen), and three time windows (5, 10, and 20 years of moni…

In-depth characterization of denitrifier communities across different soil ecosystems in the tundra

2022

Abstract Background In contrast to earlier assumptions, there is now mounting evidence for the role of tundra soils as important sources of the greenhouse gas nitrous oxide (N2O). However, the microorganisms involved in the cycling of N2O in this system remain largely uncharacterized. Since tundra soils are variable sources and sinks of N2O, we aimed at investigating differences in community structure across different soil ecosystems in the tundra. Results We analysed 1.4 Tb of metagenomic data from soils in northern Finland covering a range of ecosystems from dry upland soils to water-logged fens and obtained 796 manually binned and curated metagenome-assembled genomes (MAGs). We then sear…

Understanding tungsten erosion during inter/intra-ELM periods in He-dominated JET-ILW plasmas

2021

Tungsten erosion was quantified during inter/intra-ELM periods in He-dominated JET-ILW plasmas by optical emission spectroscopy. The intra-ELM tungsten sputtering in helium plasmas, which dominates the total W source, prevails by a factor of about 4 over inter-ELM sputtering in the investigated ELM frequency range from 90 Hz-120 Hz. He ions are mainly responsible for the W erosion during the ELMs in He plasmas. The strong in/out asymmetry of the ELM-induced W erosion is observed in He plasmas even at high ELM frequencies beyond 100 Hz. In Ohmic/L-mode plasmas and during the H-mode inter-ELM plasma phases both He2+ and Be2+ ionic species are major contributors to the W erosion. Their contrib…

Experimental Evolution Reveals a Genetic Basis for Membrane-Associated Virus Release

2021

Many animal viruses replicate and are released from cells in close association to membranes. However, whether this is a passive process or is controlled by the virus remains poorly understood. Importantly, the genetic basis and evolvability of membrane-associated viral shedding have not been investigated. To address this, we performed a directed evolution experiment using coxsackievirus B3, a model enterovirus, in which we repeatedly selected the free-virion or the fast-sedimenting membrane-associated viral subpopulations. The virus responded to this selection regime by reproducibly fixing a series of mutations that altered the extent of membrane-associated viral shedding, as revealed by fu…
