Gamma-Ray Telescopes (in "400 Years of Astronomical Telescopes")

The last half-century has seen dramatic developments in gamma-ray telescopes, from their initial conception and development through to their blossoming into full maturity as a potent research tool in astronomy. Gamma-ray telescopes are leading research in diverse areas such as gamma-ray bursts, blazars, Galactic transients, and the Galactic distribution of aluminum-26.Comment: 11 pages, 6 figures/ in "400 Years of Astronomical Telescopes: A Review of History, Science and Technology", ed.

Letter from Max Perlow to Senator Langer Regarding the Mundt-Nixon Bill, June 17, 1948

This letter dated June 17, 1948 from Max Perlow to Senator William Langer contains a resolution made by the United Furniture Workers of America adopted by their Fifth-Constitutional Convention of their International Union. They believe the Mundt-Nixon Bill is aimed at taking away the rights and liberties of the American people...https://commons.und.edu/langer-papers/1445/thumbnail.jp

Sub-dekahertz ultraviolet spectroscopy of 199Hg+

Using a laser that is frequency-locked to a Fabry-Perot etalon of high finesse and stability, we probe the 5d10 6s 2S_1/2 (F=0) - 5d9 6s 2D_5/2 (F=2) Delta-m_F = 0 electric-quadrupole transition of a single laser-cooled 199Hg+ ion stored in a cryogenic radio-frequency ion trap. We observe Fourier-transform limited linewidths as narrow as 6.7 Hz at 282 nm (1.06 X 10^15 Hz), yielding a line Q = 1.6 X 10^14. We perform a preliminary measurement of the 5d9 6s2 2D_5/2 electric-quadrupole shift due to interaction with the static fields of the trap, and discuss the implications for future trapped-ion optical frequency standards.Comment: 4 pages, 4 figures, submitted for publicatio

Keeping Steady as She Goes: A Negotiated Order Perspective on Technological Evolution

A central idea in the theory of technology cycles is that social and political mechanisms are most important during the selection of a dominant design, and that eras of incremental change are socially uninteresting periods in which innovation is driven by technological momentum and elaboration of the dominant design. In this essay, we overturn the ontological assumption that social order is inherently stable, drawing on Anselm Strauss's concept of negotiated order to analyze the persistence of a dominant design as a social accomplishment: an outcome of ongoing processes that reinforce or challenge a socially negotiated order. Thus, we shift focus from battles over standards to periods of normal innovation. We extend the technology cycles model to explain social dynamics in periods of incremental change, and to make predictions specifying how contextual conditions in standards-setting organizations affect social interaction, leading to reinforcement or challenge to a socio-technical order

Discretionary power of project managers in knowledge intensive firms and gender issues

The scarcity of women among the highly qualified professionals in business-to-business information and communication technologies (ICT), either in Europe andor in North America, has been noted as recently as the late 1990’s (Panteli, Stack, Atkinson, & Ramsay, 1999). The organization and management of work in such organizations firms is typically project-based. This has many consequences, including: long working hours with fierce resistance to shorter hoursany reduction, unpaid overtime, high management expectations of employee flexibility to meet unanticipated client demands, and the need for employees to negotiate flexible work arrangements on a case-by-cases basis with a project manager who often has much discretion on whether to accommodate such requests. We found that women are particularly disadvantaged in such a system, which could partly explain their under-representation in such jobs

Expanding Rehabilitation Beyond the Clinic—Strategies to Increase Total Restorative Therapy Time for Adults with Hemiplegia

Background: Positive neuroplastic changes involving cortical reorganization after stroke are experience dependent and are facilitated more effectively when rehabilitation occurs with high volume. Structured experiences to promote adaptive changes can be implemented during scheduled therapies in any rehabilitation setting. However, time spent in supervised restorative therapy is limited regardless of setting. Time spent in therapeutic activity can be extended by a variety of options that patients can engage in independently, that are low-cost, and that have evidence to support their use as a supplement to physical and occupational therapy. Purpose: The purpose of this paper is to present four such options for supplemental therapeutic activities to support restorative rehabilitation, including mental practice, mirror therapy, low cost virtual reality, and community group exercise classes. A sample of the evidence supporting their feasibility and effectiveness is presented. Practical guidelines for implementation are provided based on the evidence. Recommendations: Evidence based interventions can be used to extend total restorative rehabilitation time as an extension of therapy activities performed in the clinic. They are feasible and effective and can support positive neuroplastic changes in individuals with hemiplegia. These strategies can and should be implemented across practice settings by physical therapists, occupational therapists, and speech language pathologists

Fresh-blood-free diet for rearing malaria mosquito vectors

Mosquito breeding depends on the supply of fresh vertebrate blood, a major bottleneck for large-scale production of Anopheles spp. Feeding alternatives to fresh blood are thus a priority for research, outdoor large-cage trials and control interventions. Several artificial meal compositions were tested and Anopheles oogenesis, egg laying and development into the next generation of adult mosquitoes were followed. We identified blood-substitute-diets that supported ovarian development, egg maturation and fertility as well as, low progeny larval mortality, and normal development of offspring into adult mosquitoes. The formulated diet is an effective artificial meal, free of fresh blood that mimics a vertebrate blood meal and represents an important advance for the sustainability of Anopheles mosquito rearing in captivity.Agência financiadora / Número do subsídio Bill and Melinda Gates Foundation OPP1138841 Fundacao para a Ciencia e Tecnologia GHTM - UID/Multi/04413/201 CCMAR - UID/Multi/04326/2013 UID/Multi/04326/2013 RF SFRH/BPD/89811/2012 FAPEAM, Brazil 19716.UNI472.2459.20022014info:eu-repo/semantics/publishedVersio
