MOMDIS: a Glauber model computer code for knockout reactions

A computer program is described to calculate momentum distributions in stripping and diffraction dissociation reactions. A Glauber model is used with the scattering wavefunctions calculated in the eikonal approximation. The program is appropriate for knockout reactions at intermediate energy collisions (30 MeV $\leq$ E$_{lab}/$nucleon $\leq 2000$ MeV). It is particularly useful for reactions involving unstable nuclear beams, or exotic nuclei (e.g. neutron-rich nuclei), and studies of single-particle occupancy probabilities (spectroscopic factors) and other related physical observables. Such studies are an essential part of the scientific program of radioactive beam facilities, as in for instance the proposed RIA (Rare Isotope Accelerator) facility in the US.Comment: 22 pages.

Serodiagnosis of Primary Infections with Human Parvovirus 4, Finland

To determine the prevalence of parvovirus 4 infection and its clinical and sociodemographic correlations in Finland, we used virus-like particle–based serodiagnostic procedures (immunoglobulin [Ig] G, IgM, and IgG avidity) and PCR. We found 2 persons with parvovirus 4 primary infection who had mild or asymptomatic clinical features among hepatitis C virus–infected injection drug users

The Adaptability of Full Cast Crown in Preclinical Practice

A study was made to evaluate the adaptability of full cast crowns in preclinical practice of the fifth year students at Matsumoto Dental College in 1984. Gap space between the inner surface of the full cast crown and the surface of the abutment tooth was investigated with silicon material. The results were as follows: 1) The adaptability of crowns was better at the mesial surface than at the distal surface, and better at the lingual surface than at the buccal surface. 2) The adaptability of crowns was better at the axial walls, especialy in the middle, than in the cervical margin. 3) At the occulusal surface, the adaptability of crowns was worst

Self-Assembled Nanometer-Scale Magnetic Networks on Surfaces: Fundamental Interactions and Functional Properties

Nanomagnets of controlled size, organized into regular patterns open new perspectives in the fields of nanoelectronics, spintronics, and quantum computation. Self-assembling processes on various types of substrates allow designing fine-structured architectures and tuning of their magnetic properties. Here, starting from a description of fundamental magnetic interactions at the nanoscale, we review recent experimental approaches to fabricate zero-, one-, and two-dimensional magnetic particle arrays with dimensions reduced to the atomic limit and unprecedented areal density. We describe systems composed of individual magnetic atoms, metal-organic networks, metal wires, and bimetallic particles, as well as strategies to control their magnetic moment, anisotropy, and temperature-dependent magnetic behavior. The investigation of self-assembled subnanometer magnetic particles leads to significant progress in the design of fundamental and functional aspects, mutual interactions among the magnetic units, and their coupling with the environment

Programa de Enfermagem Saúde na Escola: prevenção e controle de sobrepeso/obesidade em adolescentes

Objective: To describe the construction process of an intervention in the form of a Nursing Care program to Adolescents aimed at preventing and controlling overweight/ obesity in the school environment. Method: A methodological study developed through Intervention Mapping in Natal/RN, Brazil, between October of 2015 and September of 2016, with the participation of adolescents, public school teachers and nurses in Primary Health Care. Data sources were focus groups, interviews and an integrative review. The Collective Subject Discourse was used for analysis. Results: At the end of the six stages of the Intervention Mapping, the “School Health Nursing Program” (Programa de Enfermagem Saúde na Escola) was constructed, which should be implemented over 10 months with five weekly classes of exercises and a weekly session of nursing interventions detailed in the Program. Conclusion: The nursing intervention guided by Intervention Mapping allows actions based on theories, community participation, school/service bonds, and care continuityObjective: To describe the construction process of an intervention in the form of a Nursing Care program to Adolescents aimed at preventing and controlling overweight/ obesity in the school environment.

The hierarchy-of-hypotheses approach: A synthesis method for enhancing theory development in ecology and evolution

13 páginas.- 4 figuras.- referencias.- Supplemental material is available at BIOSCI online. https://doi.org/10.1093/biosci/biaa130In the current era of Big Data, existing synthesis tools such as formal meta-analyses are critical means to handle the deluge of information. However, there is a need for complementary tools that help to (a) organize evidence, (b) organize theory, and (c) closely connect evidence to theory. We present the hierarchy-of-hypotheses (HoH) approach to address these issues. In an HoH, hypotheses are conceptually and visually structured in a hierarchically nested way where the lower branches can be directly connected to empirical results. Used for organizing evidence, this tool allows researchers to conceptually connect empirical results derived through diverse approaches and to reveal under which circumstances hypotheses are applicable. Used for organizing theory, it allows researchers to uncover mechanistic components of hypotheses and previously neglected conceptual connections. In the present article, we offer guidance on how to build an HoH, provide examples from population and evolutionary biology and propose terminological clarifications.The workshops were funded by Volkswagen Foundation (Az 92,807 and 94,246).

The importance of imprinting in the human placenta.

As a field of study, genomic imprinting has grown rapidly in the last 20 years, with a growing figure of around 100 imprinted genes known in the mouse and approximately 50 in the human. The imprinted expression of genes may be transient and highly tissue-specific, and there are potentially hundreds of other, as yet undiscovered, imprinted transcripts. The placenta is notable amongst mammalian organs for its high and prolific expression of imprinted genes. This review discusses the development of the human placenta and focuses on the function of imprinting in this organ. Imprinting is potentially a mechanism to balance parental resource allocation and it plays an important role in growth. The placenta, as the interface between mother and fetus, is central to prenatal growth control. The expression of genes subject to parental allelic expression bias has, over the years, been shown to be essential for the normal development and physiology of the placenta. In this review we also discuss the significance of genes that lack conservation of imprinting between mice and humans, genes whose imprinted expression is often placental-specific. Finally, we illustrate the importance of imprinting in the postnatal human in terms of several human imprinting disorders, with consideration of the brain as a key organ for imprinted gene expression after birth
