the purpose of this article is to introduce the thoughts of pierre bourdieu, admittedly one of the greatest sociologists of the 20th century. his works, produced within the last three decades, go beyond conventional sociological research, making a fruitful theoretical contribution to sociology. his sociology is based on a basic idea: social reality lies neither on individuals nor on groups, but...

Mirror matter is a possible dark matter candidate. It is predicted to exist if parity is an unbroken symmetry of the vacuum. The existence of the mirror matter, which in addition to gravity is coupled to our world through photon-mirror photon mixing, would result in orthopositronium (o − Ps) to mirror orthopositronium (o − Ps′) oscillations. The experimental signature of this effect is the invi...

Personal data are fuelling a fast emerging industry which transform them into added value. Harvesting these data is therefore of the outermost importance for the economy. In this paper, we study the flows of personal data at a global level, and distinguish countries based on their capacity to harvest data. We establish a cartography of international data channels on the visible and invisible We...

The study of the body and chiasm according to Merleau-Ponty is an interesting subject that deserves be explored. This because it touches "visible" "invisible" areas, which are often interpreted ambiguously when dealing with bodily functions. ambiguity arises two not used together or one chosen. Even if together, usually seen as a support complement. In fact, inseparable interrelated. Through li...

Phobia towards small animals has been treated using exposure in vivo and virtual reality. Recently, augmented reality (AR) has also been presented as a suitable tool. The first AR system developed for this purpose used visible markers for tracking. In this first system, the presence of visible markers warns the user of the appearance of animals. To avoid this warning, this paper presents a seco...

In view of the ongoing galactic (or cosmic) axion detection experiments, we compare the axion-photon-photon coupling caγγ ’s for various invisible (or very light) axion models. 11.40-q, 95.35+d, 12.60 Fr Typeset using REVTEX ∗Permanent address 1 The θ̄ parameter of the standard model is naturally understood in axion models [1]. This axion interpretation has led to the very light (or invisible) a...

OBJECTIVE To compare the performance on the detection of the invisible veins between our modified prototype device and an existing device in elderly hospitalized patients. METHODS A prospective, cross-sectional, and observational study was performed in the invisible veins in elderly patients. The major variables, skin color near the invisible veins, and diameter and depth of the invisible vei...
