Positive contact resistance soldering unit

Ohmmeter is used to indicate positive contact between electrodes and workpiece. This permits good soldering and prevents damage to electronic devices

Not So Rare: Errors of Metabolism during the Neonatal Period

During the neonatal period, the diagnosis of an error of metabolism (EM) was once thought to portend a poor prognosis or lethality. Over the past two decades, the prognosis of many EMs has changed. The critical aspect of the metabolic evaluation in a sick newborn is to rapidly identify whether there may be a metabolic problem. If there is a metabolic problem, the goal is to minimize the sequelae of the specific disorder. This review will explore how to approach and evaluate a newborn suspected of having an EM. A discussion of clinical and laboratory findings that often accompany EM will be included

Improving engineer reconnaissance in First Marine Division

This thesis explores alternative organizational designs to improve 1st Marine Division's engineer reconnaissance capability. It defines engineer reconnaissance as a complementary component of the divisions decentralized reconnaissance function, and addresses the evolution of engineer reconnaissance and its relevence to current and future maneuver commanders. This thesis expands on current deficiencies in training, organization, and coordination to define the engineer reconnaissance deficiency in terms of an organizational design problem. Four alternative solutions are proposed to develop and maintain an improved engineer reconnaissance core competency involving both structural and training changes. This thesis evaluates each alternative by three cost criteria (personnel, training, and lateral coordination requirements), and four benefit criteria (quality, acceptability, applicability, and maintainability) using an additive weighting and ranking method of analysis to determine an optimal course of action. Results of this analysis suggest that creating an engineer reconnaissance section at 1st Combat Engineer Battalion will provide the greatest engineer reconnaissance benefit to the division at the lowest costhttp://archive.org/details/improvingenginee00bantMajor, United States Marine CorpsApproved for public release; distribution is unlimited

Mapping of health technology assessment in selected countries

Objectives: The aim of this study was to develop and apply an instrument to map the level of health technology assessment (HTA) development at country level in selected countries. We examined middle-income countries (Argentina, Brazil, India, Indonesia, Malaysia, Mexico, and Russia) and countries well-known for their comprehensive HTA programs (Australia, Canada, and United Kingdom). Methods: A review of relevant key documents regarding the HTA process was performed to develop the instrument which was then reviewed by selected HTAi members and revised. We identified and collected relevant information to map the level of HTA in the selected countries. This was supplemented by information from a structured survey among HTA experts in the selected countries (response rate: 65/385). Results: Mapping of HTA in a country can be done by focusing on the level of institutionalization and the HTA process (identification, priority setting, assessment, appraisal, reporting, dissemination, and implementation in policy and practice). Although HTA is most advanced in industrialized countries, there is a growing community in middle-income countries that uses HTA. For example, Brazil is rapidly developing effective HTA programs. India and Russia are at the very beginning of introducing HTA. The other middle-income countries show intermediate levels of HTA development compared with the reference countries. Conclusions: This study presents a set of indicators for documenting the current level and trends in HTA at country level. The findings can be used as a baseline measurement for future monitoring and evaluation. This will allow a variety of stakeholders to assess the development of HTA in their country, help inform strategies, and justify expenditure for HTA

Genome-Wide Patterns of Arabidopsis Gene Expression in Nature

Organisms in the wild are subject to multiple, fluctuating environmental factors, and it is in complex natural environments that genetic regulatory networks actually function and evolve. We assessed genome-wide gene expression patterns in the wild in two natural accessions of the model plant Arabidopsis thaliana and examined the nature of transcriptional variation throughout its life cycle and gene expression correlations with natural environmental fluctuations. We grew plants in a natural field environment and measured genome-wide time-series gene expression from the plant shoot every three days, spanning the seedling to reproductive stages. We find that 15,352 genes were expressed in the A. thaliana shoot in the field, and accession and flowering status (vegetative versus flowering) were strong components of transcriptional variation in this plant. We identified between ∼110 and 190 time-varying gene expression clusters in the field, many of which were significantly overrepresented by genes regulated by abiotic and biotic environmental stresses. The two main principal components of vegetative shoot gene expression (PCveg) correlate to temperature and precipitation occurrence in the field. The largest PCveg axes included thermoregulatory genes while the second major PCveg was associated with precipitation and contained drought-responsive genes. By exposing A. thaliana to natural environments in an open field, we provide a framework for further understanding the genetic networks that are deployed in natural environments, and we connect plant molecular genetics in the laboratory to plant organismal ecology in the wild
