This paper aims to review the topic of psychic envelopes and to sketch the main outlines of this concept in infancy. We first explore the origins of the concept in Freud's "protective shield" and then its development in adult psychoanalysis before going on to see how this fits in infancy with post-Bionian psychoanalysis and development. Four central notions guide this review: (1) Freud's "prote...

BACKGROUND In eukaryotic cells the nuclear envelope isolates and protects DNA from molecules that could damage its structure or interfere with its processing. Moreover, selected protection enzymes and vitamins act as efficient guardians against toxic compounds both in the nucleoplasm and in the cytosol. The observation that a cytosolic detoxifying and antioxidant enzyme i.e. glutathione transfe...

New product development (NPD) teams enhance their change of success when they process rich and diverse market information. However, processing market information in really new NPD is subject to high levels of uncertainty and often conducted under high levels of teamautonomy. Prior research focused on intra-team factors, such as cross-functional integration, affecting market information processi...

AIM The present study investigates the role of attachment representation and mentalization as possibly protective factors in the relationship between early maltreatment and potential for violence in adolescence. METHODS For the current study, 161 adolescents, aged 14-21 years, were recruited from high schools and youth psychiatry. Early maltreatment was assessed by the Childhood Experiences o...

New concepts for protective shields for NASA’s Crew Exploration Vehicles (CEVs) and planetary probes offer improved mission safety and affordability. Hazards include radiation from cosmic rays and solar particle events, hypervelocity impacts from orbital debris/micrometeorites, and the extreme heating environment experienced during entry into planetary atmospheres. The traditional approach for ...

The article aims at constructing protective composite shields for breasts in chest computed tomography and investigating the effects of applying these new bismuth composites on dose and image quality. Polyurethane and silicon with 5% of bismuth were fabricated as a protective shield. At first, their efficiency in attenuating the X-ray beam was investigated by calculating the total attenuation c...

Abstract This work presents the results of simulation and optimization multiconductor modal filters (MFs) with circular cross section in range real geometric parameters. Five MF structures 2–4 conductors are considered a protective shield without it. Parametric was performed by amplitude time criteria order to obtain complete ultrashort pulse (USP) decomposition. As result, it achieved all maxi...

The excellent mechanical properties of graphene have enabled it as appealing candidate in the field of impact protection or protective shield. By considering a monolayer graphene membrane, in this work, we assessed its deformation mechanisms under hypervelocity impact (from 2 to 6 km/s), based on a serial of in silico studies. It is found that the cracks are formed preferentially in the zigzag ...

The Reflective Memory/Memory Channel @h&UC) system represents a modular bus-based system architecture that belongs to the class of distrtbuted shared memory systems. The RWMC system is characterized by an update consistenqv mechanism for shared data and egicient block transfers over the bus. This worh has tnw main goals. First, an extensive simulation anat’ysis using the firnch’onal Ru/MC simul...
