BARIUM IN WELDING FUME

Electrodes containing barium compounds as fluxes for use in arc welding have been examined. Fume from a cored-wire electrode with barium fluoride flux was found to contain more than 16% barium, which was substantially soluble in water or dilute acid. Exposure of a group of welders to such fume resulted in elevated barium urinary levels. Fume from stick electrodes having barium carbonate in their fluxes contained about l5–30% barium in readily soluble form. Recommendations are made concerning the control of occupational exposure of welders to barium.

In-vitro three dimensional vasculature modeling based on sensor fusion between intravascular ultrasound and magnetic tracker

This paper presents a sensor fusion between intravascular ultrasound (IVUS) and magnetic trackers for constructing the virtual reality three dimensional models of the blood vessels. We propose this approach for vasculature modeling as part of a guidance system relying on augmented reality for assistance during aortic stent graft deploy. This guidance will facilitate the alignment of the holes on the stent graft walls with the renal and mesenteric arteries ramifications. First we studied the disturbances on the magnetic tracker measurements induced by IVUS emitter after assembling the two sensors together. Then we performed a scan with the hybrid probe inside a blood silicone model submerged into a water tank, captured and fused data from both sensors. The dispersion of samples increased less than 1mm in the evaluated locations while the IVUS was activated. This enabled the construction of a three-dimensional model in virtual reality of the blood vessel model relying on the sensor fusion.

Phylogeny of the cyclostephanoid diatoms: An investigation of their morphology and stratigraphy.

The phylogeny of the Cyclostephanoid diatoms was investigated. Although several species in this group are important indicators of water quality and biostratigraphy, this is the first formal systematic study of the group. Phylogenetic reconstruction was performed for exemplar taxa within the group. The investigation utilized frustule morphology and stratigraphy with stratocladistic and classic cladistic techniques. Ingroup taxa included recent and fossil specimens from Africa, Asia, North America, and Europe. Forty-one species were detailed using scanning electron microscope techniques. Twelve of these species lack formal taxonomic description and many of the other species have not been previously investigated with the electron microscope. A disproportionate number of fossil species from the Pacific Rim were included in the ingroup, because of the abundance and age of diatomites from this area. The oldest members of Cyclostephanoid diatoms are also present in these diatomites and the area was presumed to represent the paleogeographic origin of the group. Using phylogenetic systematics, the monophylly of major genera was tested. This test was accomplished by including a group of marine &lt;italic&gt;Thalassiosira &lt;/italic&gt; species (the plicated &lt;italic&gt;Thalassiosira&lt;/italic&gt;) in the cladistic analysis and designating these species as the outgroup. Results indicate &lt;italic&gt; Cyclotella&lt;/italic&gt; is not a monophyletic group, but rather a collection of species classified by the presence of relatively pleisiomorphic features. The derived states for many of these features are character losses, which has lead to confusion in previous phenetic based classifications of the group. Proposed generic level classifications are presented, modifying the current classification of &lt;italic&gt;Cyclotella&lt;/italic&gt; to reflect monophyletic groups. This taxonomic revision would require the description of at least one new genus and as many as three new genera. Stratigraphic data contributed to the cladistic analysis, modifying the solution produced by morphological features alone. Exclusion of the stratigraphic information and fossil taxa resulted in a set of solutions consistent with the solution produced using total evidence; however, the solutions produced with the limited data set were less resolved (missing contribution from fossil species) and failed to identify the polyphyletic status of &lt;italic&gt;Cyclotella&lt;/italic&gt; (missing contribution from stratigraphy). These results demonstrate the utility of stratigraphy and fossil species in phylogenetic inference.

The temporal balance between self-renewal and differentiation of human neural stem cells requires the amyloid precursor protein

Neurogenesis in the developing human cerebral cortex occurs at a particularly slow rate owing in part to cortical neural progenitors preserving their progenitor state for a relatively long time, while generating neurons. How this balance between the progenitor and neurogenic state is regulated, and whether it contributes to species-specific brain temporal patterning, is poorly understood. Here, we show that the characteristic potential of human neural progenitor cells (NPCs) to remain in a progenitor state as they generate neurons for a prolonged amount of time requires the amyloid precursor protein (APP). In contrast, APP is dispensable in mouse NPCs, which undergo neurogenesis at a much faster rate. Mechanistically, APP cell-autonomously contributes to protracted neurogenesis through suppression of the proneurogenic activator protein–1 transcription factor and facilitation of canonical WNT signaling. We propose that the fine balance between self-renewal and differentiation is homeostatically regulated by APP, which may contribute to human-specific temporal patterns of neurogenesis.

Brain death

Restraint therapy is instituted to prevent injuries to patients or others by restricting a patient's movement. Used appropriately, restraint therapy reduces patient risk and improves outcome. Otherwise, restraint can cause accidental injury or even death. Physicians are ethically obliged to limit the use of restraints to clinically and adequately justified situations so that associated risks can be reduced. Physicians should consider whether the benefits of restraint therapy are worth the harms. This chapter presents two case studies on the appropriate use of restraint therapy. In the first case, the desire for the restraints may have been misguided. The second case exhibits the effects of restraint therapy on the family. The ethical principles of respect for patient self-determination (including informed consent obtained from surrogate decision-makers), beneficence and non-maleficence should weigh heavily in the decision to employ restraint as a mode of treatment.

Teaching general metrology: why, what, how

Abstract − Arguments are given in favour of teaching a course of General Metrology in technical universities, and some hints are formulated regarding the content of it. Several questions arise in connection with General Metrology, seen as a technical discipline, rather than a physical one. Is it useful to teach General Metrology as a separate course at a higher education level? If the answer is yes, what would be the best curriculum of such a course? When would it be most appropriate to teach the course, at the beginning or at the end of the series of basic technical disciplines? What are the main benefits such a course would bring to the general formation of the student of a technical university? The paper intends to present some aspects from our experience in this direction, after many years of teaching General Metrology at the University Politehnica of

Infection of Aedes aegypti Mosquitoes with Midgut-Attenuated Sindbis Virus Reduces, but Does Not Eliminate, Disseminated Infection

When a mosquito ingests an arbovirus during a blood meal, the arbovirus must escape from the midgut of the vector and infect the salivary glands in order to be transmitted to a new host. We used tissue-specific miRNA targeting to examine the requirement for Sindbis virus (SINV) to replicate in midgut epithelium in order to cause disseminated infection in the mosquito Aedes aegypti .

Protein binding to a single termination-associated sequence in the mitochondrial DNA D-loop region.

A methylation protection assay was used in a novel manner to demonstrate a specific bovine protein-mitochondrial DNA (mtDNA) interaction within the organelle (in organello). The protected domain, located near the D-loop 3' end, encompasses a conserved termination-associated sequence (TAS) element which is thought to be involved in the regulation of mtDNA synthesis. In vitro footprinting studies using a bovine mitochondrial extract and a series of deleted mtDNA templates identified a approximately 48-kDa protein which binds specifically to a single TAS element also protected within the mitochondrion. Because other TAS-like elements located in close proximity to the protected region did not footprint, protein binding appears to be highly sequence specific. The in organello and in vitro data, together, provide evidence that D-loop formation is likely to be mediated, at least in part, through a trans-acting factor binding to a conserved sequence element located 58 bp upstream of the D-loop 3' end.

Keratinocyte and hepatocyte growth factors in the lung: roles in lung development, inflammation, and repair

A growing body of evidence indicates that the epithelial-specific growth factors keratinocyte growth factor (KGF), fibroblast growth factor (FGF)-10, and hepatocyte growth factor (HGF) play important roles in lung development, lung inflammation, and repair. The therapeutic potential of these growth factors in lung disease has yet to be fully explored. KGF has been best studied and has impressive protective effects against a wide variety of injurious stimuli when given as a pretreatment in animal models. Whether this protective effect could translate to a treatment effect in humans with acute lung injury needs to be investigated. FGF-10 and HGF may also have therapeutic potential, but more extensive studies in animal models are needed. Because HGF lacks true epithelial specificity, it may have less potential than KGF and FGF-10 as a targeted therapy to facilitate lung epithelial repair. Regardless of their therapeutic potential, studies of the unique roles played by these growth factors in the pathogenesis and the resolution of acute lung injury and other lung diseases will continue to enhance our understanding of the complex pathophysiology of inflammation and repair in the lung.

Geographical pathology of cancer of the uterine cervix.

The availability of age-standardized cancer incidences for different parts of the world has enabled a thorough and meaningful analysis of the geographical distribution of cancer of the uterine cervix. The high morbidity and mortality from cervical cancer reported for most European countries and North America at the beginning of this century has, in recent years, been superseded by those for Asian, African, Latin American and Caribbean countries with the provision of additional data. Striking differences in cervical cancer incidences have been observed among various ethnic groups in Africa which seem to reflect variations in the intensity of certain environmental influences. Cervix cancer is uncommon in the white population of North America and Europe with the exception of West Germany, Denmark, Sweden and Yugoslavia. In the United States, the highest incidence occurs in Puerto Rican women of New York City and the Latin population of the South. The very low incidence in Jewish women is virtually the same in New York City as in Israel. This world-wide survey has shown that poor sexual hygiene rather than lack of male circumcision per se is a more important aetiological factor in cervical cancer.

Plastic Deformation Analysis of a New Mega-Subcontrolled Structural System (MSCSS) Subjected to Seismic Excitation

This paper seeks to examine the plastic deformation and seismic structural response of a mega-subcontrolled structural system (MSCSS) subjected to strong seismic excitations. Different MSCSS configurations were modeled with nonlinear finite elements, and nonlinear dynamic analyses were performed to examine their behaviors. This paper introduces a novel and optimized MSCSS configuration, configuration 30, which demonstrates remarkable results for the reduction of plastic strain. Utilizing a steel plate shear wall enhances the seismic structural integrity of this system (SPSW). This configuration improved the mean equivalent plastic strain of columns and beams by 51% and 80%, respectively. In addition, a comparison between unstiffened and ring-shaped infill panels of SPSWs demonstrates that ring-shaped infill panels offer greater lateral stiffness and energy dissipation with a 44% reduction in maximum equivalent plastic strain. Compared to configuration 1, configuration 30 exhibited the most controlled structural response, as the minimum residual story drift improvement was 70% in the first, second, and third substructures, respectively, and the maximum coefficient of variation (COV) was 16% and 32% in the acceleration and displacement responses, respectively.

Towards semantic TV services a hybrid Semantic Web Services approach

Abstract. We are investigating the current Semantic Web Services approaches in order to select the most appropriate approach to build semantic internet TV services. Two major approaches are prominent which are top-down and bottom-up approaches, the former being heavyweight and supporting complex reasoning tasks and the latter being lightweight with limited reasoning capacity. We defend our assumption that semantic TV services require the strengths of both approaches and introduce a novel hybrid approach.
