Background: To evaluate the effectiveness and safety of the support given to women by a companion of their choice during labor and delivery. Methods: A total of 212 primiparous women were enrolled in a randomized controlled clinical trial carried out between February 2004 and March 2005. One hundred and five women were allocated to the group in which support was permitted and 107 to the group i...

In 1990 J-L. Krivine introduced the notion of storage operators. They are λ-terms which simulate call-by-value in the call-by-name strategy and they can be used in order to modelize assignment instructions. J-L. Krivine has shown that there is a very simple second order type in AF2 type system for storage operators using Gődel translation of classical to intuitionistic logic. In order to modeli...

Independence in everyday life is a concern of many frail older people. There is a vision that in the near future this group will considerably gain independence and improve their quality of life by relying not only on human caregivers – who cannot grant round-the-clock assistance – but in addition on smart computer-based help capable of imitating human care-giving behaviour. This vision is expre...

Stratospheric sudden warmings are the clearest and strongest manifestation of dynamical coupling in the stratosphere–troposphere system. While many sudden warmings have been individually documented in the literature, this study aims at constructing a comprehensive climatology: all major midwinter warming events are identified and classified, in both the NCEP–NCAR and 40-yr ECMWF Re-Analysis (ER...

In this paper we integrate a humanoid robot with a powered wheelchair with the aim of lowering the cognitive requirements needed for powered mobility. We propose two roles for this companion: pointing out obstacles and giving directions. We show that children enjoyed driving with the humanoid companion by their side during a field-trial in an uncontrolled environment. Moreover, we present the r...

The analysis of gravitational Wave (GW) data from advanced LIGO provides the mass each companion binary black holes as source GWs. events corresponding to GW is above $20$ M$_\odot$ which much larger than astrophysical detected by x-ray observations. In this work, we examine primordial (PBHs) events. Assuming that $100\%$ dark matter made PBHs, estimate rate at these objects make binaries, merg...

let $p(lambda)$ be an $n$-square complex matrix polynomial, and $1 leq k leq n$ be a positive integer. in this paper, some algebraic and geometrical properties of the $k$-numerical range of $p(lambda)$ are investigated. in particular, the relationship between the $k$-numerical range of $p(lambda)$ and the $k$-numerical range of its companion linearization is stated. moreover, the $k$-numerical ...

Skin diseases are common in exotic companion mammal medicine. Some of the diseases are infectious, with potential transmission towards the owners, while others have a metabolic etiology. A list of commonly found dermatologic conditions in exotic companion mammals can be found in Table 1. The approach to skin diseases in exotic companion mammals is similar to that of skin diseases in other compa...
