MCH Pheromone for Preventing Douglas-Fir Beetle Infestation in Windthrown Trees

A granular controlled-release formulation (98 percent inert, 2 percent 3-methyl-2-cyclohexen-1-one) was applied May 11-13, 1982, at 4.48 kg/ha to 76.9 ha of uninfested windthrown Douglas-fir by helicopter with a modified aerial spreader of 1.13 m³ capacity. Granules measured on treated plots averaged 2.04-2.69 kg/ha, sufficient to reduce Douglas-fir beetle (Dendroctonus pseudotsugae) infestation 96.4 percent by late June. The same MCH treatment reduced spruce beetle (Dendroctonus rufipennis) attacks by 55 percent in fewer, intermingled windthrown Engelmann spruce

Multiple Myeloma Baseline Immunoglobulin G Level and Pneumococcal Vaccination Antibody Response

Infections are a major cause of morbidity and mortality in multiple myeloma (MM), a cancer of the immune system. Vaccination clinical efficacy endpoints have not been demonstrated, and there are limited data on surrogate markers of efficacy. This pilot study evaluated sequential immunologic markers after standard pneumococcal vaccination (PV) in patients with MM and non-MM controls. Vaccination was standard for PV (PCV13 or PPV23), with laboratory testing at baseline and at 2, 4, 12 and 24 weeks after vaccination. Immunoglobulin G (IgG) antibodies to pneumococcal antigens were detected by ELISA. Prevaccination total IgG levels and IgG subclass levels were also measured by ELISA. Four of 6 controls responded with at least a 2-fold increase in antibody concentration; only 2 controls had a sustained increase in concentration. Six of 8 patients with MM had at least a 2-fold antibody increase; however, only 2 of these patients showed a sustained increase of antipneumococcal antibody. Response rate differences were not statistically significant in this small pilot, and there was no relationship between responsiveness to PV and initial serum total IgG levels or IgG subclasses at study entry. Future prospective studies are needed to ascertain the immunological and clinical efficacy and effectiveness of various vaccines and vaccination strategies in MM

The impact of maternal supplementation during pregnancy and the first 6 months postpartum on the growth status of the next child born after the intervention period: Follow‐up results from Bangladesh and Ghana

Pregnancy and breastfeeding make demands on maternal nutrient stores. The extent of depletion and the degree to which nutrient stores are replenished between pregnancies has implications for a mother\u27s nutritional status at conception of the subsequent child and therefore that child\u27s birth outcomes and growth. Using follow‐up data collected several years after a randomized effectiveness trial conducted in rural Bangladesh and a randomized efficacy trial conducted in semiurban Ghana, we evaluated the impact of maternal supplementation with small‐quantity lipid‐based nutrient supplements (LNS) or multiple micronutrients (MMN) through pregnancy (the index pregnancy) and 6 months postpartum on the growth status of the next living younger sibling conceived and born after the index pregnancy. In both Bangladesh (n = 472 younger siblings) and Ghana (n = 327 younger siblings), there were no overall differences in the growth status or the prevalence of undernutrition among younger siblings whose mothers had received LNS (or MMN, Ghana only) during and after the index pregnancy compared with the younger siblings of mothers who had received iron plus folic acid (IFA) during the index pregnancy (Ghana) or during and for 3 months after the index pregnancy (Bangladesh). These findings do not indicate that preconception nutrition interventions do not improve child growth. Rather, they suggest that any benefits of maternal LNS or MMN supplementation during one pregnancy and for 6 months postpartum are unlikely to extend to the growth of her next child beyond any effects due to IFA alone

Immunomagnetic t-lymphocyte depletion (ITLD) of rat bone marrow using OX-19 monoclonal antibody

Graft versus host disease (GVHD) may be abrogated and host survival prolonged by in vitro depletion of T lymphocytes from bone marrow (BM) prior to allotransplantation. Using a mouse anti-rat pan T-lymphocyte monoclonal antibody (0×19) bound to monosized, magnetic, polymer beads, T lymphocytes were removed in vitro from normal bone marrow. The removal of the T lymphocytes was confirmed by flow cytometry. Injection of the T-lymphocyte-depleted bone marrow into fully allogeneic rats prevents the induction of GVHD and prolongs host survival. A highly efficient technique of T-lymphocyte depletion using rat bone marrow is described. It involves the binding of OX-19, a MoAb directed against all rat thy-mocytes and mature peripheral T lymphocytes, to monosized, magnetic polymer spheres. Magnetic separation of T lymphocytes after mixing the allogeneic bone marrow with the bead/OX-19 complex provides for a simple, rapid depletion of T lymphocytes from the bone marrow. In vitro studies using flow cytometry and the prevention of GVHD in a fully allogeneic rat bone marrow model have been used to demonstrate the effectiveness of the depletion procedure. © 1989 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted

Nimbus-7 Total Ozone Mapping Spectrometer (TOMS) data products user's guide

Two tape products from the Total Ozone Mapping Spectrometer (TOMS) aboard the Nimbus-7 have been archived at the National Space Science Data Center. The instrument measures backscattered Earth radiance and incoming solar irradiance; their ratio -- the albedo -- is used in ozone retrievals. In-flight measurements are used to monitor changes in the instrument sensitivity. The algorithm to retrieve total column ozone compares the observed ratios of albedos at pairs of wavelengths with pair ratios calculated for different ozone values, solar zenith angles, and optical paths. The initial error in the absolute scale for TOMS total ozone is 3 percent, the one standard-deviation random error is 2 percent, and the drift is +/- 1.5 percent over 14.5 years. The High Density TOMS (HDTOMS) tape contains the measured albedos, the derived total ozone amount, reflectivity, and cloud-height information for each scan position. It also contains an index of SO2 contamination for each position. The Gridded TOMS (GRIDTOMS) tape contains daily total ozone and reflectivity in roughly equal area grids (110 km in latitude by about 100-150 km in longitude). Detailed descriptions of the tape structure and record formats are provided

Where constructionism and critical realism converge: interrogating the domain of epistemological relativism

The paper interrogates the status, nature and significance of epistemological relativism as a key element of constructionism and critical realism. It finds that epistemological relativism is espoused by authorities in critical realism and marginalized or displaced in the field of management and organization studies, resulting in forms of analysis that are empirically, but not fully critically, realist. This evaluation prompts reflection on the question of whether, how and with what implications epistemological relativism might be recast at the heart of critical realist studies of management and organization

(Re)imagining the ‘backstreet’:Anti-abortion campaigning against decriminalisation in the UK

The risk of death or serious injury from ‘backstreet abortions’ was an important narrative in the 20th century campaign to liberalise abortion in the UK. Since then, clinical developments have reduced the overall health risks of abortion, and international health organisations have been set up to provide cross-border, medically safe abortions to places where it is unlawful, offering advice and, where possible, supplying abortion pills. These changes mean that pro-choice campaigns in Europe have often moved away from the risks of ‘backstreet abortions’ as a central narrative when campaigning for abortion liberalisation. In contrast, in the UK, anti-abortion activists are increasingly using ideas about ‘backstreet abortions’ to resist further liberalisation. These claims can be seen to fit within a broader shift from morals to risk within moral regulation campaigns and build on anti-abortion messages framed as being ‘pro-women’, with anti-abortion activists claiming to be the ‘savers’ of women. Using a parliamentary debate as a case study, this article will illustrate these trends and show how the ‘backstreet’ metaphor within anti-abortion campaigns builds on three interconnected themes of ‘abortion-as-harmful’, ‘abortion industry’, and ‘abortion culture’. This article will argue that the anti-abortion movement’s adoption of risk-based narratives contains unresolved contradictions due to the underlying moral basis of their position. These are exacerbated by the need, in this case, to defend legislation that they fundamentally disagree with. Moreover, their attempts to construct identifiable ‘harms’ and vulnerable ‘victims’, which are components of moral regulation campaigns, are unlikely to be convincing in the context of widespread public support for abortion

'On the Wet Side of the Womb’:The construction of mothers in anti-abortion activism in England and Wales

Across the UK, there has been an increase in anti-abortion activism outside abortion clinics. The activism deployed includes explicitly religious activities such as ‘prayerful witnessing’ and ‘pavement counselling’, which aim to discourage women from entering clinics. This article stems from a wider ethnographic study of public activism over abortion to determine what claims about motherhood are being made within these debates. Two arguments are presented. First, how women’s role as mothers is central and essentialised in anti-abortion discourses, with the body of the mother often disappearing as activists seek to erode the distinction between a foetus and a baby by constructing pregnancy as a foetal environment. Motherhood is constructed as ‘natural’ and sacred, therefore abortion must be damaging because it destroys women’s ‘natural’ position. Second, the article argues that although the activists’ arguments are always religiously framed, their activism takes place in a largely secular context, meaning that they have to find ways of appealing to secular audiences. This leads to a complex interrelationship between secular and religious discourses, where theological viewpoints sit alongside ‘scientific’ claims to buttress activists’ views. This article explores how the presence and absence of mothers within activists’ narratives is due to the tensions between religiously based understandings of motherhood, and the need to appeal to a secular audience

Environment Orientation : a structured simulation approach for agent-based complex systems

Complex systems are collections of independent agents interacting with each other and with their environment to produce emergent behaviour. Agent-based computer simulation is one of the main ways of studying complex systems. A naive approach to such simulation can fare poorly, due to large communication overhead, and due to the scope for deadlock between the interacting agents sharing a computational platform. Agent interaction can instead be considered entirely from the point of view of the environment(s) within which the agents interact. Structuring a simulation using such Environment Orientation leads to a simulation that reduces communication overhead, that is effectively deadlock-free, and yet still behaves in the manner required. Additionally the Environment Orientation architecture eases the development of more sophisticated large-scale simulations, with multiple kinds of complex agents, situated in and interacting with multiple kinds of environments. We describe the Environment Orientation simulation architecture. We report on a number of experiments that demonstrate the effectiveness of the Environment Orientation approach: a simple flocking system, a flocking system with multiple sensory environments, and a flocking system in an external environment
