    Incorporating behavioral health care into patient centered medical homes is critical for improving patient health and care quality while reducing costs. Despite documented effectiveness of behavioral health integration (BHI) in primary care settings, implementation is limited outside of large health systems. We conducted a survey of BHI in primary care practices participating in the Comprehensive Primary Care (CPC) initiative, a four-year multi-payer initiative of the Centers for Medicare and Medicaid Services (CMS). We sought to explore associations between practice characteristics and the extent of BHI to illuminate possible factors influencing successful implementation. We fielded a survey that addressed six substantive domains (integrated space, training, access, communication and coordination, treatment planning, and available resources) and five behavioral health conditions (depression, anxiety, pain, alcohol use disorder, and cognitive function). Descriptive statistics compared BHI survey respondents to all CPC practices, documented the availability of behavioral health providers, and primary care and behavioral health provider communication. Bivariate relationships compared provider and practice characteristics and domain scores. One hundred sixty-one of 188 eligible primary care practices completed the survey (86% response rate). Scores indicated basic to good baseline implementation of BHI in all domains, with lowest scores on communication and coordination and highest scores for depression. Higher scores were associated with: having any behavioral health provider, multispecialty practice, patient-centered medical home designation, and having any communication between behavioral health and primary care providers. This study provides useful data on opportunities and challenges of scaling BHI integration linked to primary care transformation. Payment reform models such as CPC can assist in BHI promotion and development.

    Full Text Available The title compound, pentabarium tetraindium hexaantimony, was synthesized by an indium-flux reaction and its structure features layers composed of edge-sharing In2Sb6 units. The voids between the In4Sb6 layers are filled by Ba2+ cations, which are all surrounded by six Sb atoms and form bicapped octahedral or triangular prismatic coordination geometries. There are five barium ions in the asymmetric unit: one has no imposed crystallographic symmetry, two lie on mirror planes and two have mm2 point symmetry. The two In atoms and four Sb atoms in the asymmetric unit all lie on general crystallographic positions.

    The Carbon Products Consortium (CPC) is an industry, university, government cooperative research team which has evolved over the past seven years to produce and evaluate coal-derived feedstocks for carbon products. The members of the Carbon Products Consortium are UCAR Carbon Company, Koppers Industries, CONOCO, Aluminum Company of America, AMOCO Polymers, and West Virginia University. The Carbon and Insulation Materials Technology Group at Oak Ridge National Laboratory, Fiber Materials Inc., and BASF Corporation are affiliates of the CPC. The initial work on coal-derived nuclear graphites was supported by a grant to WVU, UCAR Carbon, and ORNL from the U.S. DOE New Production Reactor program. More recently, the CPC program has been supported through the Fossil Energy Materials program and through PETC`s Liquefaction program. The coal processing technologies involve hydrogenation, extraction by solvents such as N-methyl pyrolidone and toluene, material blending, and calcination. The breadth of carbon science expertise and manufacturing capability available in the CPC enables it to address virtually all research and development issues of importance to the carbon products industry.

  7. SLUDGE BATCH 6 ACCEPTANCE EVALUATION: RADIONUCLIDE CONCENTRATIONS IN TANK 51 SB6 QUALIFICATION SAMPLE PREPARED AT SRNL

    Presented in this report are radionuclide concentrations required as part of the program of qualifying Sludge Batch Six (SB6) for processing in the Defense Waste Processing Facility (DWPF). The SB6 material is currently in Tank 51 being washed and prepared for transfer to Tank 40. The acceptance evaluation needs to be completed prior to the transfer of the material in Tank 51 to Tank 40. The sludge slurry in Tank 40 has already been qualified for DWPF and is currently being processed as SB5. The radionuclide concentrations were measured or estimated in the Tank 51 SB6 Qualification Sample prepared at Savannah River National Laboratory (SRNL). This sample was prepared from the three liter sample of Tank 51 sludge slurry (HTF-51-09-110) taken on October 8, 2009. The sample was delivered to SRNL where it was initially characterized in the Shielded Cells. Under the direction of the Liquid Waste Organization it was then modified by eight washes, nine decants, an addition of Pu from Canyon Tank 16.3, and an addition of NaNO{sub 2}. This final slurry now has a composition expected to be similar to that of the slurry in Tank 51 after final preparations have been made for transfer of that slurry to Tank 40. Determining the radionuclide concentrations in this Tank 51 SB6 Qualification Sample is part of the work requested in Technical Task Request (TTR) No. HLW-DWPF-TTR-2009-0014. The work with this qualification sample is covered by a Task Technical and Quality Assurance Plan and an Analytical Study Plan. The radionuclides included in this report are needed for the DWPF Radiological Program Evaluation, the DWPF Waste Acceptance Criteria (TSR/WAC) Evaluation, and the DWPF Solid Waste Characterization Program (TTR Task I.2). Radionuclides required to meet the Waste Acceptance Product Specifications (TTR Task II.2.) will be measured at a later date after the slurry from Tank 51 has been transferred to Tank 40. Then a sample of the as-processed SB6 will be taken and transferred

    The Savannah River National Laboratory (SRNL) accepted a technical task request (TTR) from Waste Solidification Engineering to perform simulant tests to support the qualification of Sludge Batch 8 (SB8) and to develop the flowsheet for SB8 in the Defense Waste Processing Facility (DWPF). These efforts pertained to the DWPF Chemical Process Cell (CPC). Separate studies were conducted for frit development and glass properties (including REDOX). The SRNL CPC effort had two primary phases divided by the decision to drop Tank 12 from the SB8 constituents. This report focuses on the second phase with SB8 compositions that do not contain the Tank 12 piece. A separate report will document the initial phase of SB8 testing that included Tank 12. The second phase of SB8 studies consisted of two sets of CPC studies. The first study involved CPC testing of an SB8 simulant for Tank 51 to support the CPC demonstration of the washed Tank 51 qualification sample in the SRNL Shielded Cells facility. SB8-Tank 51 was a high iron-low aluminum waste with fairly high mercury and moderate noble metal concentrations. Tank 51 was ultimately washed to about 1.5 M sodium which is the highest wash endpoint since SB3-Tank 51. This study included three simulations of the DWPF Sludge Receipt and Adjustment Tank (SRAT) cycle and Slurry Mix Evaporator (SME) cycle with the sludge-only flowsheet at nominal DWPF processing conditions and three different acid stoichiometries. These runs produced a set of recommendations that were used to guide the successful SRNL qualification SRAT/SME demonstration with actual Tank 51 washed waste. The second study involved five SRAT/SME runs with SB8-Tank 40 simulant. Four of the runs were designed to define the acid requirements for sludge-only processing in DWPF with respect to nitrite destruction and hydrogen generation. The fifth run was an intermediate acid stoichiometry demonstration of the coupled flowsheet for SB8. These runs produced a set of processing

    The UNICOS (UNified Industrial COntrol System) framework was created back in 1998. Since then a noticeable number of applications in different domains have used this framework. Furthermore UNICOS has been formalized and its supervision layer has been reused in other kinds of applications (e.g. monitoring or supervisory tasks) where a control layer is not necessarily UNICOS oriented. The process control package has been reformulated as the UNICOS CPC package (Continuous Process Control) and a reengineering process has been followed. The drive behind these noticeable changes was (1) being able to upgrade to the new more performing IT technologies in the automatic code generation, (2) being flexible enough to create new additional device types to cope with other needs (e.g. Vacuum or Cooling and Ventilation applications) without major impact on the framework or the PLC code baselines and (3) enhance the framework with new functionalities (e.g. recipes). This publication addresses the motivation, changes, new fun...

    The Synthetic Biology conference series (SBx.0) is the preeminent academic meeting in synthetic biology. Organized by the BioBricks Foundation, the SBx.0 conference series brings together leading researchers, students, industry executives, and policy makers from around the world to share, consider, debate, and plan efforts to make biology easier to engineer. Historically held every two years, the SBx.0 conferences are held in alternating locations in the United States, Europe, and Asia to encourage global participation and collaboration so that the ramifications of synthetic biology research and development are most likely to be safe ethical, and beneficial. On 9-11 July 2013, the 6th installment of the synthetic biology conference series (SB6.0) was held on the campus of Imperial College London (http://sb6.biobricks.org). The SB6.0 conference was attended by over 700 people, and many more were able to participate via video digital conference (http://sb6.biobricks.org/digital-conference/). Over the course of three days, the SB6.0 conference agenda included plenary sessions, workshops, and poster presentations covering topics ranging from the infrastructure needs arising when “Systematic Engineering Meets Biological Complexity” and design-led considerations for “Connecting People and Technologies” to discussions on “Engineering Biology for New Materials,” “Assessing Risk and Managing Biocontainment,” and “New Directions for Energy and Sustainability.” The $10,150 grant awarded by the U.S. Department of Energy (DE-SC0010233) to the BioBricks Foundation was used to provide partial reimbursement for the travel expenses of leading researchers from the United States to speak at the SB6.0 conference. A total of $9,450 was used to reimburse U.S. speakers for actual expenses related to the SB6.0 conference, including airfare (economy or coach only), ground transportation, hotel, and registration fees. In addition, $700 of the grant was used to offset

    Growth, development, virulence and secondary metabolism in fungi are governed by heterotrimeric G proteins (G proteins). A Gβ-like protein called Gib2 has been shown to function as an atypical Gβ in Gpa1-cAMP signaling in Cryptococcus neoformans. We found that the previously reported CpcB (cross pathway control B) protein is the ortholog of Gib2 in Aspergillus nidulans and Aspergillus fumigatus. In this report, we further characterize the roles of CpcB in governing growth, development and toxigenesis in the two aspergilli. The deletion of cpcB results in severely impaired cellular growth, delayed spore germination, and defective asexual sporulation (conidiation) in both aspergilli. Moreover, CpcB is necessary for proper expression of the key developmental activator brlA during initiation and progression of conidiation in A. nidulans and A. fumigatus. Somewhat in accordance with the previous study, the absence of cpcB results in the formation of fewer, but not micro-, cleistothecia in A. nidulans in the presence of wild type veA, an essential activator of sexual development. However, the cpcB deletion mutant cleistothecia contain no ascospores, validating that CpcB is required for progression and completion of sexual fruiting including ascosporogenesis. Furthermore, unlike the canonical GβSfaD, CpcB is not needed for the biosynthesis of the mycotoxin sterigmatocystin (ST) as the cpcB null mutant produced reduced amount of ST with unaltered STC gene expression. However, in A. fumigatus, the deletion of cpcB results in the blockage of gliotoxin (GT) production. Further genetic analyses in A. nidulans indicate that CpcB may play a central role in vegetative growth, which might be independent of FadA- and GanB-mediated signaling. A speculative model summarizing the roles of CpcB in conjunction with SfaD in A. nidulans is presented.

    A method for applying the Maximum Entropy Method (MEM) to Chopped Photometric Channel (CPC) IRAS additional observations is illustrated. The original CPC data suffered from problems with repeatability which MEM is able to cope with by use of a noise image, produced from the results of separate data scans of objects. The process produces images of small areas of sky with circular Gaussian beams of approximately 30 in. full width half maximum resolution at 50 and 100 microns. Comparison is made to previous reconstructions made in the far-infrared as well as morphologies of objects at other wavelengths. Some projects with this dataset are discussed.

    GeSb6Te is a chalcogenide-based phase change material that has shown great ptoential for use in solid-state memory devices. The crystallization kinetics of amorphous thin films of GeSb6Te during laser crystallization were followed with dynamic transmission electron microscopy, a photo-emission electron microscopy technique with nanosecond-scale time resolution. Nine-frame movies of crystal growth were taken during laser crystallization. The nucleation rate is observed to be very low and the growth rates are very high, up to 10.8 m s(-1) for amorphous as-deposited films and significantly higher for an amorphous film subject to sub-threshold laser annealing before crystallization. The measured growth rates exceed any directly measured growth rate of a phase change material. The crystallization is reminiscent of explosive crystallization of elemental semiconductors both in the magnitude of the growth rate and in the resulting crystalline microstructures.

  15. The R3-MYB gene GhCPC negatively regulates cotton fiber elongation.

    Full Text Available Cotton (Gossypium spp. fibers are single-cell trichomes that arise from the outer epidermal layer of seed coat. Here, we isolated a R3-MYB gene GhCPC, identified by cDNA microarray analysis. The only conserved R3 motif and different expression between TM-1 and fuzzless-lintless mutants suggested that it might be a negative regulator in fiber development. Transgenic evidence showed that GhCPC overexpression not only delayed fiber initiation but also led to significant decreases in fiber length. Interestingly, Yeast two-hybrid analysis revealed an interaction complex, in which GhCPC and GhTTG1/4 separately interacted with GhMYC1. In transgenic plants, Q-PCR analysis showed that GhHOX3 (GL2 and GhRDL1 were significantly down regulated in -1-5 DPA ovules and fibers. In addition, Yeast one-hybrid analysis demonstrated that GhMYC1 could bind to the E-box cis-elements and the promoter of GhHOX3. These results suggested that GhHOX3 (GL2 might be downstream gene of the regulatory complex. Also, overexpression of GhCPC in tobacco led to differential loss of pigmentation. Taken together, the results suggested that GhCPC might negatively regulate cotton fiber initiation and early elongation by a potential CPC-MYC1-TTG1/4 complex. Although the fibers were shorter in transgenic cotton lines than in the wild type, no significant difference was detected in stem or leaf trichomes, even in cotton mutants (five naked seed or fuzzless, suggesting that fiber and trichome development might be regulated by two sets of genes sharing a similar model.

    First-principles density functional based electronic structure calculations are performed in order to clarify the influence of FeSb6 octahedral deformations on the structural and electronic structure properties of LaFe 4Sb12. Our results show that octahedral tiltings correlate with the band dispersions and, consequently, the band masses. While total energy variation points at an enhanced role of lattice anharmonicity, flat bands emerge from a redistribution of the electronic states. © 2011 Elsevier B.V. All rights reserved.

    2015-05-24

    In November 2013, the Irish Regulator for emergency medical technicians (EMTs) introduced the first mandatory requirement for registrants to demonstrate evidence of continuous professional development (CPD)/continuous professional competence (CPC). This qualitative study assessed the experience of practitioners with CPC-related materials provided to them by the Regulator in addition to identifying perceived or encountered practical challenges and suggested improvements six months following introduction of the requirement. Five fora were utilised, comprising two distinct groupings: a group of student EMTs (n = 62) and four discrete groups of qualified EMTs (total n = 131) all of whom had commenced the newly-introduced CPC process. All 193 volunteers were members of the Civil Defence (an auxiliary/voluntary organisation) and represented a nationwide distribution of personnel. Responses were categorised as 'perceived' challenges to CPC, relating to student EMTs, and 'experienced' challenges to CPC, relating to qualified EMTs. Responses also included suggestions from both groups of EMTs on how to improve the current system and guidance material. Audio/visual recordings were made, transcribed and then analysed using NVivo (version 10). A coding framework was developed which identified unifying themes. All participants agreed that CPC for pre-hospital practitioners was a welcomed initiative believing that CPC activities would help ensure that EMTs maintain or enhance their skills and be better enabled to provide quality care to the patients they might encounter. Two specific areas were identified by both groups as being challenging: 1) the practicalities of completing CPC and 2) the governance and administration of the CPC process. Challenging practicalities included: ability of voluntary EMTs to gain access to operational placements with paramedics and advanced paramedics; the ability to experience the number of patient contacts required and the definition of

    The UNICOS (UNified Industrial COntrol System) framework, and concretely the CPC (Continuous Process Control) package, has been extensively used in the domain of continuous processes (e.g. cryogenics, gas flows) and also in others specific to the LHC machine as the collimators environmental measurements interlock system. The application of the UNICOS-CPC to other kind of processes: vacuum and the cooling and ventilation cases are depicted here. One of the major challenges was to figure out whether the model and devices created so far were also adapted for other type of processes (e.g. Vacuum). To illustrate this challenge two domain use cases will be shown: ISOLDE vacuum control system and the RFQ4 and STP18 (cooling & ventilation) control systems. Both scenarios will be illustrated emphasizing the adaptability of the UNICOS CPC package to create those applications and highlighting the discovered needed features to include in a future version of the UNICOS CPC package. This paper will a...

    The Continuous Process Control package (CPC) is one of the components of the CERN Unified Industrial Control System framework (UNICOS) [1]. As a part of this framework, UNICOS-CPC provides a well defined library of device types, amethodology and a set of tools to design and implement industrial control applications. The new CPC version uses the software factory UNICOS Application Builder (UAB) [2] to develop CPC applications. The CPC component is composed of several platform oriented plugins PLCs and SCADA) describing the structure and the format of the generated code. It uses a resource package where both, the library of device types and the generated file syntax, are defined. The UAB core is the generic part of this software, it discovers and calls dynamically the different plug-ins and provides the required common services. In this paper the UNICOS CPC6 package is introduced. It is composed of several plug-ins: the Instance generator and the Logic generator for both, Siemens and Schneider PLCs, the SCADA g...

    A series of experiments have been completed at TNX for the sludge-only REDOX adjusted flowsheet using Tank 42 sludge simulant in response to the Technical Task Request HLW/DWPT/TTR-980013 to increase CPC batch sizes. By increasing the initial SRAT batch size, a melter feed batch at greater waste solids concentration can be prepared and thus increase melter output per batch by about one canister. The increased throughput would allow DWPF to dispose of more waste in a given time period thus shortening the overall campaign.

    The main objective of this work was to investigate the biosorption performance of unmodified and Cetylpyridinium chloride (CPC)-modified biomass of Penicillium YW 01 for Acid Blue 25 (AB 25). Maximum biosorption capacity of AB 25 onto CPC-modified biosorbent was 118.48 mg g(-1) under phosphoric-phosphate buffer with initial dye concentration of 200 mg L(-1) at 30°C. The biosorption pattern of AB 25 onto unmodified biosorbent in aqueous solution and phosphoric-phosphate buffer was well fitted with both Langmuir and Freundlich isotherm models. While the equilibrium data of CPC-modified biosorbent in aqueous solution and phosphoric-phosphate buffer failed to fit the Freundlich isotherm model, indicating the monolayer biosorption formed onto CPC-modified biosorbent. The values of initial biosorption rate of biosorbent in phosphoric-phosphate buffer were found to be higher than that of corresponding values in aqueous solution, indicating phosphoric-phosphate buffer enhanced the initial biosorption rate of biosorption process. Weber-Morris model analysis indicated that the boundary layer effect had more influence on the biosorption process in phosphoric-phosphate buffer. The BET surface area of CPC-modified biosorbent (0.5761 m(2) g(-1)) was larger than that of unmodified biomass (0.3081 m(2) g(-1)). Possible dye-biosorbent interactions were confirmed by Fourier transform infrared spectroscopy. Copyright © 2011 Elsevier B.V. All rights reserved.

    CAPRICE (CPC) is a R3-type MYB transcription factor, which induces root-hair cell differentiation in Arabidopsis thaliana. The CPC homologous gene ENHANCER TRY AND CPC1 (ETC1) has a similar function to CPC, and acts in concert with CPC. The CPC protein moves between root epidermal cells, from hairless cells to the neighboring cells, and promotes root-hair differentiation. Therefore, ETC1 is predicted to have movement ability similar to that of CPC. In this study, we generated ETC1:ETC1:GFP and CPC:ETC1:GFP transgenic plants to clarify whether ETC1 exhibits cell-to-cell movement. Transgenic plants showed many-root-haired and trichome-less phenotypes, similar to those observed in CPC:CPC:GFP plants, suggesting a similar function of ETC1 and CPC. However, the ETC1:GFP fusion protein located exclusively to the hairless cells in both ETC1:ETC1:GFP and CPC:ETC1:GFP transgenic plants. These results indicate that, unexpectedly, the ETC1 protein cannot move in the root epidermis from hairless cells to the neighboring cells. Copyright © 2017 Elsevier GmbH. All rights reserved.

    Arthrospira platensis is an economically important cyanobacterium; and it has been used widely in food and pharmaceutical industries. The phycocyanin (PC) from A. platensis is extremely valuable in medicine and molecular biology due to its antioxidation and anti-tumoring activity and applicability as fluorescence protein tag. In present study, two recombinant plasmids, one contained the phycocyanobilin (PCB)-producing genes ( hox1 and pcyA) while the other contained the phycobiliprotein gene ( cpcB) and the lyase gene (either cpcS/U or cpcT), were constructed and synchronically transferred into E. coli in order to test the the activities of relevant lyases for catalysing PCB addition to CpcB during synthesizing fluorescent PC holo-β-subunit (β-PC) of A. platensis. As was evidenced by the fluorescence emitted at a peak specific for PC, CpcB was successfully synthesized in E. coli, to which co-expressed PCBs attached though at a relatively low efficiency. The results showed that the attachment of PCBs to CpcB were carried out mainly by co-expressed CpcS/U but CpcB also showed some autocatalytic activity. Currently, no CpcT activity was detected in this E. coli expression system. Further studies will be conducted to improve the efficiency of fluorescent PC synthesis in E. coli.

    An experimental study. To clarify the optimal insertion timing of transpedicular screws when the initial fixation strength reaches in maximum as calcium phosphate cement (CPC) hardens, in cases augmented by CPC to the vertebrae. CPC goes easily into the bone trabeculae and excels in the bone compatibility. However, it is still unknown as for differences of fixation effects by CPC hardening time at actual insertion of the pedicle screw. Fifty-seven vertebrae obtained from 11 human cadavers. The CPC and titanium pedicle screws were used. Experimental groups were decided as follows. (1) Control group (without CPC). (2) CPC group (augmented with CPC); the mixed CPC infused into the screw hole, afterwards the pedicle screw inserted at a set time (passage time from the initiation of powder and liquid agent mixing). The CPC group was further divided into 3 subgroups, with respect to insertion time of the pedicle screws: 2, 5, and 10 minute subgroups. Maximum pull-out strength was compared, and cross sectioned specimens of the 5 and 10 minute groups were prepared and observed. CPC group showed a pull-out strength of about 177% that of the control group. For inserting timing of the pedicle screw and pull-out strength, no apparent statistically significant difference was found between each subgroups, although the 10-minute group showed the lowest. Cross sectional observations revealed that the CPC diffused deeper into the bone trabeculae in the 5-minute group than in the 10 minutes. CPC augmentation enabled an average 77% increase of the maximum pull-out strength compared to the control group. The study of screw insertion timing augmented with CPC was indicative of the fact that an increase in the initial fixation of the pedicle screw can be achieved when the screw is inserted before initiation of CPC hardening.

    2014-03-02

    Internationally, continuing professional competence (CPC) is an increasingly important issue for all health professionals. With the imminent introduction of a CPC framework for paramedics and advanced paramedics (APs) in Ireland, this paper aims to identify factors that will inform the implementation of this CPC framework by seeking stakeholder input into the development of a CPC model for use by the regulatory body. Our secondary objective is to determine the attitudes of registrants towards CPC and what they consider as optimal educational outcomes and activities, for the purposes of CPC. All paramedics and APs registered in Ireland (n = 1816) were invited by email to complete an anonymous on-line survey. The study instrument was designed based on CPD questionnaires used by other healthcare professions. Quantitative and qualitative analyses were performed. The overall response rate was 43% (n = 789), with 82% of APs and 38% of paramedics participating. Eighty-nine per cent agreed that registration was of personal importance; 74% agreed that evidence of CPC should be maintained and 39% believed that persistent failure to meet CPC requirements should mandate denial of registration. From a pre-determined list of activities, respondents indicated practical training scenarios (94%), cardiac re-certification (92%), e-learning supplemented by related practice (90%) and training with simulation manikins (88%) were most relevant, while e-learning alone (36%), project work (27%) and reading journal articles (24%) were least relevant. Irish Paramedics and APs are supportive of CPC linked with their professional development and registration. Blended learning, involving evidence of patient contact, team-based learning and practical skills are preferred CPC activities.

  18. Searching bioremediation patents through Cooperative Patent Classification (CPC).

    Patent classification systems have traditionally evolved independently at each patent jurisdiction to classify patents handled by their examiners to be able to search previous patents while dealing with new patent applications. As patent databases maintained by them went online for free access to public as also for global search of prior art by examiners, the need arose for a common platform and uniform structure of patent databases. The diversity of different classification, however, posed problems of integrating and searching relevant patents across patent jurisdictions. To address this problem of comparability of data from different sources and searching patents, WIPO in the recent past developed what is known as International Patent Classification (IPC) system which most countries readily adopted to code their patents with IPC codes along with their own codes. The Cooperative Patent Classification (CPC) is the latest patent classification system based on IPC/European Classification (ECLA) system, developed by the European Patent Office (EPO) and the United States Patent and Trademark Office (USPTO) which is likely to become a global standard. This paper discusses this new classification system with reference to patents on bioremediation.

    Available cholinergic drugs for treating Alzheimer's disease (AD) provide modest symptomatic benefit. We hypothesized that co-administration of a peripheral anticholinergic to reduce dose-limiting adverse effects (AEs) would enable the safe/tolerable use of higher cholinesterase inhibitor doses and thus improve their antidementia efficacy. A modified single-blind, ascending-dose, phase IIa study of donepezil plus solifenacin (CPC-201) lasting 26 weeks was conducted in 41 patients with probable AD of moderate severity. Entry criteria included the use of donepezil at a dose of 10 mg/day during the preceding 3 months. The primary outcome measure was the maximum tolerated dose (MTD) of donepezil achieved (to protocol limit of 40 mg/day) when administered with the anticholinergic solifenacin 15 mg/day. Secondary measures included assessments of cognitive and global function, as well as of AEs. The mean ± SD donepezil MTD increased to 38 ± 0.74 mg/day (median 40 mg/day; p donepezil AE frequency, especially gastrointestinal, allowed this dose increase. There were no drug-related serious AEs or clinically significant laboratory abnormalities. At 26 weeks, Alzheimer's Disease Assessment Scale Cognitive Component scores in the efficacy evaluable population improved by 0.35 ± 0.85 points over baseline (p donepezil and 5.4 ± 0.84 points above historic placebo (both p donepezil AEs by co-administration of solifenacin allows the safe administration of substantially higher cholinesterase inhibitors doses that may augment cognitive and global benefits in patients with AD.

With the introduction of the first CPC framework for Emergency Medical Technicians (EMTs) and the imminent introduction of CPC for Paramedics and Advanced Paramedics (APs) in Ireland, this study aimed to identify attitudes towards CPC and factors that might influence such a framework. All EMTs (n = 925), Paramedics and APs (n = 1816) registered in Ireland were invited by email to complete an anonymous on-line survey. The study instrument was designed based on continuous professional development (CPD) questionnaires used by other healthcare professions. Quantitative and qualitative analyses were performed. The overall response rates were: EMTs 43% (n = 399), Paramedics and APs 43% (n = 789), with 82% of APs and 38% of Paramedics participating. The majority of participants in all groups agreed that registration was of personal importance and that evidence of CPC should be maintained; 39% of Paramedics/APs and 78% of EMTs believed that persistent failure to meet CPC requirements should mandate denial of registration. From a pre-determined list of activities, in excess of 88% of all respondents indicated practical training scenarios, cardiac re-certification, e-learning supplemented by related practice, and training with simulation manikins were most relevant to these roles. However, least relevant to them were: e-learning alone (Paramedic/AP 36%; EMT 35%); project work (Paramedic/AP 27%; EMT 48%); and appraisal of journal articles (Paramedic/AP 24%; EMT 39%). Irish EMTs, Paramedics and Advanced Paramedics were supportive of CPC and favoured a 'mixed' model approach which includes: blended learning, practical skills, simulation, practical/team-based exercises, e-learning combined with practical skills, and evidence of patient contact. It is hoped that these insights will inform the CPC guidelines to be introduced.

  7. Molecular and phylogenetic characterization of two species of the genus Nostoc (Cyanobacteria based on the cpcB-IGS-cpcA locus of the phycocyanin operon

    Full Text Available Traditionally, the taxonomy of the genus Nostoc is based on morphological and physiological characters. The extreme morphological variability of the Nostoc species, due to their life cycle and environmental conditions, hampers the correct identification of the individual species. This is also one of the reasons for the disputed taxonomic positions and relationships between the genera Anabaena–Aphanizomenon as well as between Anabaena–Nostoc. Therefore, it is necessary to use additional markers for development of a polyphasic classification system of order Nostocales. In light of this, we here present the first molecular and phy-logenetic characterization of two species of the genus Nostoc (Nostoc linckia and Nostoc punctiforme based on the cpcB-IGS-cpcA locus of the phycocyanin oper-on. The phylogenetic position of these two species within order Nostocales as well as within division Cyanobacteria has been determined. Our results indicate that genus Nostoc is heterogeneous. Analysis of the IGS region between cpcB and cpcA showed that Nostoc and Anabaena are distinct genera. Reported molecular and phylogenetic data will be useful to solve other problematic points in the tax-onomy of genera Aphanizomenon, Anabaena and Nostoc.

    As in other countries, the Irish Regulator for Pre-Hospital practitioners, the Pre-Hospital Emergency Care Council (PHECC), will introduce a Continuous Professional Competence (CPC) framework for all Emergency Medical Technicians (EMTs), Paramedics and Advanced Paramedics (APs). This framework involves EMTs participating in regular and structured training to maintain professional competence and enable continuous professional developments. To inform the development of this framework, this study aimed to identify what EMTs consider the optimum educational outcomes and activity and their attitude towards CPC. All EMTs registered in Ireland (n = 925) were invited via email to complete an anonymous online survey. Survey questions were designed based on Continuous Professional Development (CPD) questionnaires used by other healthcare professions. Quantitative and qualitative analyses were performed. Response rate was 43% (n = 399). 84% of participants had been registered in Ireland for less than 24 months, while 59% had been registered EMTs for more than one year. Outcomes were: evidence of CPC should be a condition for EMT registration in Ireland (95%), 78% believed that EMTs who do not maintain CPC should be denied the option to re-register. Although not required to do so at the time of survey, 69% maintained a professional portfolio and 24% had completed up to 20 hours of CPC activities in the prior 12 months. From a list of 22 proposed CPC activities, 97% stated that practical scenario-based exercises were most relevant to their role. E-learning curricula without practical components were considered irrelevant (32%), but the majority of participants (91%) welcomed access to e-learning when supplemented by related practical modules. EMTs are supportive of CPC as a key part of their professional development and registration. Blended learning, which involves clinical and practical skills and e-learning, is the optimum approach.

Simulant processing was successful using 100 ppm of 747 antifoam added prior to nitric acid instead of 200 ppm. This is a potential area for DWPF to cut antifoam usage in any future test program. An additional 100 ppm was added before formic acid addition. Foaming during formic acid addition was not observed. No build-up of oily or waxy material was observed in the off-gas equipment. Lab-scale mercury stripping behavior was similar to SB6 and SB7a. More mercury was unaccounted for as the acid stoichiometry increased.

    Full Text Available [Purpose/significance] A detailed comparison of the mapping between the Cooperative Patent Classification System (CPC and the International Patent Classification System (IPC is intended to provide references for the use of CPC and IPC for patent classification.[Method/process]This paper made a detailed mapping number analysis between CPC and IPC in terms of the class, subclass, group and subgroup on their common A-H sections. [Result/conclusion] The classification principle between the Cooperative Patent Classification System (CPC and the International Patent Classification System (IPC is basically consistent and CPC is more subdivided than the IPC. The “2000 series (indexing” and the Y section of the new technology are added, showing CPC’s high extensibility. We believe that as a strong compatibility and high degree classification system, CPC will become an efficient tool to improve the efficiency of retrieval and optimize the review quality.

When the constructed plasmid pETDuet-6 bearing five genes involved in the biosynthesis of CpcA was transformed into E. coli, the screened transformant acquired a pronounced blue color. Visualization of proteins on SDS-PAGE gel showed a 29 kDa distinct band, corresponding to the theoretically calculated molecular weight of CpcA. Upon exposure to Zn(2+) and UV illumination, the CpcA band was fluorescent. Western blot analysis using His-tag monoclonal antibody confirmed the expression of CpcA in the recombinant E. coli. After the optimization of critical medium components by response surface methodology, the recombinant cells produced 22.29 mg/l of CpcA. The recombinant CpcA displayed a strong ability to scavenge three free radicals ·OH, ·DPPH, and O2 (-) to protect against the oxidation of linoleic acid and to restore the growth of E. coli cells injured by DPPH and H2O2 at a relatively low concentration. These results lay a good foundation for the production and future use of CpcA.

    Chamberlain engineers designed a 3X compound parabolic concentrating (CPC) collector for the subject contract. The collector is a completely housed, 105.75 x 44.75 x 10.23-inch, 240-pound unit with six each evacuated receiver assemblies, a center manifold and a one-piece glass cover. A truncated version of a CPC trough reflector system and the General Electric Company tubular evacuated receiver have been integrated with a mass producible collector design suitable for operation at 250 to 450/sup 0/F. The key criterion for optimization of the design was minimization of the cost per Btu collected annually at an operating temperature of 400/sup 0/F. The reflector is a 4.1X design truncated to a total height of 8.0 inches with a resulting actual concentration ratio of 2.6 to 1. The manifold is an insulated area housing the fluid lines which connect the six receivers in series with inlet and outlet tubes extending from one side of the collector at the center. The reflectors are polished, anodized aluminum which are shaped by the roll form process. The housing is painted, galvanized steel, and the cover glass is 3/16-inch thick tempered, low iron glass. The collector requires four slope adjustments per year for optimum effectiveness. Chamberlain produced ten 3X CPC collectors for the subject contract. Two collectors were used to evaluate assembly procedures, six were sent to the project officer in Albuquerque, New Mexico, one was sent to Argonne National Laboratory for performance testing and one remained with the Company. A manufacturing cost study was conducted to estimate limited mass production costs, explore cost reduction ideas and define tooling requirements. The final effort discussed shows the preliminary design for application of a 3X CPC solar collector system for use in the Iowa State Capitol complex.

    Solar disinfection (SODIS) of water is a well-known, effective treatment process which is practiced at household level in many developing countries. However, this process is limited by the small volume treated and there is no indication of treatment efficacy for the user. Low cost glass tube reactors, together with compound parabolic collector (CPC) technology, have been shown to significantly increase the efficiency of solar disinfection. However, these reactors still require user input to control each batch SODIS process and there is no feedback that the process is complete. Automatic operation of the batch SODIS process, controlled by UVA-radiation sensors, can provide information on the status of the process, can ensure the required UVA dose to achieve complete disinfection is received and reduces user work-load through automatic sequential batch processing. In this work, an enhanced CPC photo-reactor with a concentration factor of 1.89 was developed. The apparatus was automated to achieve exposure to a pre-determined UVA dose. Treated water was automatically dispensed into a reservoir tank. The reactor was tested using Escherichia coli as a model pathogen in natural well water. A 6-log inactivation of E. coli was achieved following exposure to the minimum uninterrupted lethal UVA dose. The enhanced reactor decreased the exposure time required to achieve the lethal UVA dose, in comparison to a CPC system with a concentration factor of 1.0. Doubling the lethal UVA dose prevented the need for a period of post-exposure dark inactivation and reduced the overall treatment time. Using this reactor, SODIS can be automatically carried out at an affordable cost, with reduced exposure time and minimal user input.

    Full Text Available A convergência para os padrões contábeis internacionais tem se tornado um assunto relevante, com agenda definida para sua adesão em muitos países ao redor do mundo. No Brasil, coube ao CPC a responsabilidade de emitir pronunciamentos contábeis de acordo com as normas IFRS. Cada documento emitido pelo CPC corresponde a uma norma internacional de contabilidade emitida pelo IASB. Este trabalho tem como objetivo comparar os pronunciamentos do CPC com as normas do IASB e verificar a existência de diferenças entre os mesmos. Para tanto, realizou-se uma pesquisa documental aos pronunciamentos do CPC e às normas do IASB. Utilizou-se a técnica da análise de conteúdo, tendo o tema como unidade de significação. O universo de análise compreendeu os 65 pronunciamentos técnicos que estão sendo utilizados nas demonstrações contábeis das companhias brasileiras, emitidos pelo CPC entre os anos de 2007 a 2011. Os resultados apontaram para a existência de diferenças entre os pronunciamentos emitidos pelo CPC e as normas emitidas pelo IASB, as quais foram agrupadas em quatro categorias de análise. Após análise, concluiu-se que as diferenças apontadas não prejudicam a declaração de que as demonstrações contábeis consolidadas brasileiras, preparadas de acordo com os CPCs estão de acordo com as normas do IASB.

  11. Translation Initiation from Conserved Non-AUG Codons Provides Additional Layers of Regulation and Coding Capacity

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available Neurospora crassa cpc-1 and Saccharomyces cerevisiae GCN4 are homologs specifying transcription activators that drive the transcriptional response to amino acid limitation. The cpc-1 mRNA contains two upstream open reading frames (uORFs in its >700-nucleotide (nt 5′ leader, and its expression is controlled at the level of translation in response to amino acid starvation. We used N. crassa cell extracts and obtained data indicating that cpc-1 uORF1 and uORF2 are functionally analogous to GCN4 uORF1 and uORF4, respectively, in controlling translation. We also found that the 5′ region upstream of the main coding sequence of the cpc-1 mRNA extends for more than 700 nucleotides without any in-frame stop codon. For 100 cpc-1 homologs from Pezizomycotina and from selected Basidiomycota, 5′ conserved extensions of the CPC1 reading frame are also observed. Multiple non-AUG near-cognate codons (NCCs in the CPC1 reading frame upstream of uORF2, some deeply conserved, could potentially initiate translation. At least four NCCs initiated translation in vitro. In vivo data were consistent with initiation at NCCs to produce N-terminally extended N. crassa CPC1 isoforms. The pivotal role played by CPC1, combined with its translational regulation by uORFs and NCC utilization, underscores the emerging significance of noncanonical initiation events in controlling gene expression.

    The purpose of this multi-phase explorative in vivo animal/surgical and in vitro multi-test experimental study was to (1) create a 3wt%-nanostrontium hydroxyapatite-enhanced calcium phosphate cement (Sr-HA/CPC) for increasing bone formation and (2) creating a simvastatin-loaded poly(lactic-co-glycolic acid) (SIM-loaded PLGA) microspheres plus CPC composite (SIM-loaded PLGA+nanostrontium-CPC). The third goal was the extensive assessment of multiple in vitro and in vivo characteristics of the above experimental explorative products in vitro and in vivo (animal and surgical studies). Physical and chemical properties of the prepared Sr-HA/CPC were evaluated. MTT assay and alkaline phosphatase activities, and radiological and histological examinations of Sr-HA/CPC, CPC and negative control were compared. X-ray diffraction (XRD) indicated that crystallinity of the prepared cement increased by increasing the powder-to-liquid ratio. Incorporation of Sr-HA into CPC increased MTT assay (biocompatibility) and ALP activity (P<0.05). Histomorphometry showed greater bone formation after 4weeks, after implantation of Sr-HA/CPC in 10 rats compared to implantations of CPC or empty defects in the same rats (n=30, ANOVA P<0.05). METHODS AND RESULTS PERTAINING TO SIM-LOADED PLGA MICROSPHERES+NANOSTRONTIUM-CPC COMPOSITE: After SEM assessment, the produced composite of microspheres and enhanced CPC were implanted for 8weeks in 10 rabbits, along with positive and negative controls, enhanced CPC, and enhanced CPC plus SIM (n=50). In the control group, only a small amount of bone had been regenerated (localized at the boundary of the defect); whereas, other groups showed new bone formation within and around the materials. A significant difference was found in the osteogenesis induced by the groups sham control (16.96±1.01), bone materials (32.28±4.03), nanostrontium-CPC (24.84±2.6), nanostrontium-CPC-simvastatin (40.12±3.29), and SIM-loaded PLGA+nanostrontium-CPC (44.8±6.45) (ANOVA P

    The CAPRICE (CPC) encodes an R3-type MYB transcription factor, which promotes root-hair differentiation. Previously, we showed that the CPC protein moves from the non-hair cell to the neighboring cell and induces root-hair differentiation in Arabidopsis. In addition, we proposed two cell-to-cell movement signal sequences, S1 and S2, in CPC. However, an S1:2xGFP:S2 chimera protein did not move between root epidermal cells. Here, we show that the S1 and S2 sequences do not confer cell-to-cell movement or nuclear localization ability to a GFP protein. The ENHANCER OF TRY AND CPC1 (ETC1) gene encodes the CPC homolog R3 MYB; this protein does not possess cell-to-cell movement ability or the S1 sequence. To elucidate whether the S1 sequence can induce cell-to-cell movement ability in ETC1, CPCp:S1:ETC1:2xGFP was constructed and introduced into Arabidopsis. Our results indicate that the addition of the S1 sequence was not sufficient for ETC1 to acquire cell-to-cell movement ability.

    A new solar cooker incorporating Non Imaging Optics (CPC type optics) and heat pipe technology is presented in this work. A CPC collector concentrates solar radiation and the heat pipe transfers the energy from the CPC collector to the cooker. The energy can be delivered directly to the cooking pan or stored for subsequent use, for example, late in the afternoon. This device allows cooking inside the house and at the end of the day, which is not possible with conventional solar cookers. The use of different types of cooking pans is allowed and larger quantities of food can be cooked. The first experimental results show that this cooker is more effective than common solar cookers considering the energy storage and following delivery. (Author)

  15. MODELING OF DIRECT SOLAR RADIATION IN A COMPOUND PARABOLIC COLLECTOR (CPC WITH THE RAY TRACING TECHNIQUE

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available El colector parabólico compuesto (CPC es una tecnología ampliamente usada en aplicaciones fotoquímicas, como las reacciones fotocatalíticas. Para propósitos cinéticos en esta clase de reacciones, se debe conocer la distribución de la radiación ya que la velocidad de reacción depende la absorción de fotones. En el presente trabajo desarrolló un modelo matemático que permitió simular el fenómeno de reflexión de la radiación solar directa en un CPC. Las ecuaciones se evaluaron usando geometría analítica y cálculo vectorial, primero para calcular las coordenadas cartesianas de la superficie reflectiva. Luego estos puntos se usaron para calcular las trayectorias de los rayos incidentes y reflejados en cualquier instante. La radiación incidente en el receptor se graficó independientemente, mostrando la distribución de la energía directa que llega directamente al absorbedor. La longitud de la involuta también se calculó a partir de estos datos, los cuales pueden resultar muy útiles para su construcción. Los resultados obtenidos a partir de las simulaciones muestran que la distribución de la energía incidente en la superficie del absorbedor depende de la reflectividad de la superficie del CPC. La energía incidente es mayor en la parte superior que en la inferior del absorbedor, y son más convenientes valores altos de reflectividad para distribuciones de energía más uniformes. Este modelo matemático puede ser una primera aproximación para modelos más complejos de absorción de fotones que incluyan radiación solar directa en aplicaciones fotoquímicas o fototérmicas.

    Full Text Available The CAPRICE (CPC-like MYB gene family encodes R3-type MYB transcription factors in Arabidopsis. There are six additional CPC-like MYB sequences in the Arabidopsis genome, including TRYPTICHON (TRY, ENHANCER OF TRY AND CPC1 and 2 (ETC1 and ETC2, ENHANCER OF TRY AND CPC3/CPC-LIKE MYB3 (ETC3/CPL3, and TRICHOMELESS1 and 2 (TCL1 and TCL2. We independently identified CPC-LIKE MYB4 (CPL4, which was found to be identical to TCL2. RT-PCR analysis showed that CPL4 is strongly expressed in shoots, including true leaves, but not in roots. Promoter-GUS analyses indicated that CPL4 is specifically expressed in leaf blades. Although CPC expression was repressed in 35S::ETC1, 35S::ETC2 and 35S::CPL3 backgrounds, CPL4 expression was not affected by ETC1, ETC2 or CPL3 over-expression. Notably, several chimeric transcripts may result from inter-genic alternative splicing of CPL4 and ETC2, two tandemly repeated genes on chromosome II. At least two chimeric transcripts named CPL4-α and CPL4-β are expected to encode complete CPC-like MYB proteins.

    2015-01-01

    Full Text Available This paper presents theoretical and experimental optical evaluation and comparison of symmetric Compound Parabolic Concentrator (CPC and V-trough collector. For direct optical properties comparison, both concentrators were deliberately designed to have the same geometrical concentration ratio (1.96, aperture area, absorber area, and maximum concentrator length. The theoretical optical evaluation of the CPC and V-trough collector was carried out using a ray-trace technique while the experimental optical efficiency and solar energy flux distributions were analysed using an isolated cell PV module method. Results by simulation analysis showed that for the CPC, the highest optical efficiency was 95% achieved in the interval range of 0° to ±20° whereas the highest outdoor experimental optical efficiency was 94% in the interval range of 0° to ±20°. For the V-tough collector, the highest optical efficiency for simulation and outdoor experiments was about 96% and 93%, respectively, both in the interval range of 0° to ±5°. Simulation results also showed that the CPC and V-trough exhibit higher variation in non-illumination intensity distributions over the PV module surface for larger incidence angles than lower incidence angles. On the other hand, the maximum power output for the cells with concentrators varied depending on the location of the cell in the PV module.

    Policy Points: Collaboration across payers to align financial incentives, quality measurement, and data feedback to support practice transformation is critical, but challenging due to competitive market dynamics and competing institutional priorities. The Centers for Medicare & Medicaid Services or other entities convening multipayer initiatives can build trust with other participants by clearly outlining each participant's role and the parameters of collaboration at the outset of the initiative. Multipayer collaboration can be improved if participating payers employ neutral, proactive meeting facilitators; develop formal decision-making processes; seek input on decisions from practice representatives; and champion the initiative within their organizations. With increasing frequency, public and private payers are joining forces to align goals and resources for primary care transformation. However, sustaining engagement and achieving coordination among payers can be challenging. The Comprehensive Primary Care (CPC) initiative is one of the largest multipayer initiatives ever tested. Drawing on the experience of the CPC initiative, this paper examines the factors that influence the effectiveness of multipayer collaboration. This paper draws largely on semistructured interviews with CPC-participating payers and payer conveners that facilitated CPC discussions and on observation of payer meetings. We coded and analyzed these qualitative data to describe collaborative dynamics and outcomes and assess the factors influencing them. We found that several factors appeared to increase the likelihood of successful payer collaboration: contracting with effective, neutral payer conveners; leveraging the support of payer champions, and seeking input on decisions from practice representatives. The presence of these factors helped some CPC regions overcome significant initial barriers to achieve common goals. We also found that leadership from the Centers for Medicare & Medicaid

  19. The role of the RACK1 ortholog Cpc2p in modulating pheromone-induced cell cycle arrest in fission yeast.

    Directory of Open Access Journals (Sweden)

    Magdalena Mos

    Full Text Available The detection and amplification of extracellular signals requires the involvement of multiple protein components. In mammalian cells the receptor of activated C kinase (RACK1 is an important scaffolding protein for signal transduction networks. Further, it also performs a critical function in regulating the cell cycle by modulating the G1/S transition. Many eukaryotic cells express RACK1 orthologs, with one example being Cpc2p in the fission yeast Schizosaccharomyces pombe. In contrast to RACK1, Cpc2p has been described to positively regulate, at the ribosomal level, cells entry into M phase. In addition, Cpc2p controls the stress response pathways through an interaction with Msa2p, and sexual development by modulating Ran1p/Pat1p. Here we describe investigations into the role, which Cpc2p performs in controlling the G protein-mediated mating response pathway. Despite structural similarity to Gβ-like subunits, Cpc2p appears not to function at the G protein level. However, upon pheromone stimulation, cells overexpressing Cpc2p display substantial cell morphology defects, disorientation of septum formation and a significantly protracted G1 arrest. Cpc2p has the potential to function at multiple positions within the pheromone response pathway. We provide a mechanistic interpretation of this novel data by linking Cpc2p function, during the mating response, with its previous described interactions with Ran1p/Pat1p. We suggest that overexpressing Cpc2p prolongs the stimulated state of pheromone-induced cells by increasing ste11 gene expression. These data indicate that Cpc2p regulates the pheromone-induced cell cycle arrest in fission yeast by delaying cells entry into S phase.

    Drosophila melanogaster lacks DNMT1/DNMT3 based methylation machinery. Despite recent reports confirming the presence of low DNA methylation in Drosophila; little is known about the methyltransferase. Therefore, in this study, we have aimed to investigate the possible functioning of DNA methyltransferase in Drosophila. The 14 K oligo microarray slide was incubated with native cell extract from adult Drosophila to check the presence of the methyltransferase activity. After incubation under appropriate conditions, the methylated oligo sequences were identified by the binding of anti 5-methylcytosine monoclonal antibody. The antibody bound to the methylated oligos was detected using Cy3 labeled secondary antibody. Methylation sensitive restriction enzyme mediated PCR was used to assess the methylation at a few selected loci identified on the array. It could be seen that a few of the total oligos got methylated under the assay conditions. Analysis of methylated oligo sequences provides evidence for the presence of de novo methyltransferase activity and allows identification of its sequence specificity in adult Drosophila. With the help of methylation sensitive enzymes we could detect presence of CpC methylation in the selected genomic regions. This study reports presence of an active DNA methyltransferase in adult Drosophila, which exhibits sequence specificity confirmed by presence of asymmetric methylation at corresponding sites in the genomic DNA. It also provides an innovative approach to investigate methylation specificity of a native methyltransferase.

    Isolates of the toxic, N(2)-fixing species Cylindrospermopsis raciborskii from various geographic locations were analyzed with respect to their genetic diversity based on the nifH and cpcBA-IGS genes. Gene sequences clustered according to their geographic origin, with the nifH sequences separating into European, Australian, and American groups and the cpcBA-IGS sequences separating into American and European or Australian groups. PCR primers for both genes were designed to exclusively amplify DNA from Cylindrospermopsis species, and an additional primer set for cpcBA-IGS was designed to specifically amplify the American C. raciborskii strains.

    To study the feasibility of tissue engineered bone constructed with simvastatin carried by PLGA/CPC and bone marrow stromal cells (BMSCs) and screen the effective drug loading of simvastatin. Solvent casting-particle leaching technology combined with the phase separation process was used to prepare the different concentrations (simvastatin mass: 0.1, 0.5, 1 mg) of simvastatin carried by PLGA/CPC composite scaffold materials. Scanning electron microscopy was used to observe the porosity and drug release curve was drawn; Alizarin red staining and type I collagen staining were applied to observe the effect of osteogenic medium and simvastatin on the role of BMSCs to the osteogenetic differentiation. The induced passage 3 cells after dil staining were mixed with the composite scaffold material to a complex. Scanning electron microscopy and laser confocal microscope were used to observe the adhesion on the complex. CCK-8 and alkaline phosphatase (ALP) were applied to observe the proliferation and differentiation. SPSS 18.0 software package was used for statistical analysis. The scaffold porosity was more than 90% with an average aperture of 200-300 μm. The drug released slowly. There was no obvious interpretation. Type I collagen showed positive expression. Alizarin red staining proofed the formation of mineralization nodules in group which was induced with the conditional medium and simvastatin. 0.5 mg group showed cells adhered to the inner surface of the scaffold material and could significantly promote the proliferation and differentiation of cells. Combination of simvastatin and osteogenic medium can effectively promote the differentiation of BMSCs. Simvastatin carried by PLGA/CPC scaffold materials is an ideal tissue engineering scaffold material. PLGA/CPC scaffold containing 0.5 mg simvastatin can effectively promote the proliferation and differentiation of BMSCs. Supported by Natural Science Foundation of Jilin Province (201215052).

    Full Text Available Based on the theories of agency and stakeholder is expected that those responsible for preparing the financial statements are committed to the disclosure of relevant information to users. The purpose of this work is to make an analysis from the information provided by public and private companies of the agribusiness sector, focusing on disclosure requirements of the CPC 29. However, the differential of this work is the analysis separately of public and private companies. This is a descriptive and qualitative research, based on analysis of financial statements of 2010. For this, a check list based on CPC 29 was applied, allowing the comparison between public and private companies through of the Mann-Whitney test. The data analyzed allow concluding that most of the sample opted to use fair value as the measurement basis, but did not disclose the assumptions used in the method adopted. This situation undermines the comparative analysis of financial statements and decreases its relevance to users, besides allowing practices of earnings management. The disclosure of the types of biological assets and the reconciliation of the changes in the carrying amount of these were made for much of the sample companies. However, there was a low disclosure of risk and control restrictions for the composition of the historical cost of biological assets. These evidences show that companies, public or private, complied partially the requirements of CPC 29. Moreover, in the separate analysis, the statistical test shows no difference in terms of disclosure between the two groups. These results should be analyzed with caution considering the limitations of this research and the adaptation period for which companies face in the first adoption of CPC 29.

    Full Text Available Anaeromyxobacter dehalogenans strain 2CP-C is a versaphilic delta-Proteobacterium distributed throughout many diverse soil and sediment environments. 16S rRNA gene phylogenetic analysis groups A. dehalogenans together with the myxobacteria, which have distinguishing characteristics including strictly aerobic metabolism, sporulation, fruiting body formation, and surface motility. Analysis of the 5.01 Mb strain 2CP-C genome substantiated that this organism is a myxobacterium but shares genotypic traits with the anaerobic majority of the delta-Proteobacteria (i.e., the Desulfuromonadales. Reflective of its respiratory versatility, strain 2CP-C possesses 68 genes coding for putative c-type cytochromes, including one gene with 40 heme binding motifs. Consistent with its relatedness to the myxobacteria, surface motility was observed in strain 2CP-C and multiple types of motility genes are present, including 28 genes for gliding, adventurous (A- motility and 17 genes for type IV pilus-based motility (i.e., social (S- motility that all have homologs in Myxococcus xanthus. Although A. dehalogenans shares many metabolic traits with the anaerobic majority of the delta-Proteobacteria, strain 2CP-C grows under microaerophilic conditions and possesses detoxification systems for reactive oxygen species. Accordingly, two gene clusters coding for NADH dehydrogenase subunits and two cytochrome oxidase gene clusters in strain 2CP-C are similar to those in M. xanthus. Remarkably, strain 2CP-C possesses a third NADH dehydrogenase gene cluster and a cytochrome cbb(3 oxidase gene cluster, apparently acquired through ancient horizontal gene transfer from a strictly anaerobic green sulfur bacterium. The mosaic nature of the A. dehalogenans strain 2CP-C genome suggests that the metabolically versatile, anaerobic members of the delta-Proteobacteria may have descended from aerobic ancestors with complex lifestyles.

    Risk-stratified care management is essential to improving population health in primary care settings, but evidence is limited on the type of risk stratification method and its association with care management services. We describe risk stratification patterns and association with care management services for primary care practices in the Comprehensive Primary Care (CPC) initiative. We undertook a qualitative approach to categorize risk stratification methods being used by CPC practices and tested whether these stratification methods were associated with delivery of care management services. CPC practices reported using 4 primary methods to stratify risk for their patient populations: a practice-developed algorithm (n = 215), the American Academy of Family Physicians' clinical algorithm (n = 155), payer claims and electronic health records (n = 62), and clinical intuition (n = 52). CPC practices using practice-developed algorithm identified the most number of high-risk patients per primary care physician (282 patients, P = .006). CPC practices using clinical intuition had the most high-risk patients in care management and a greater proportion of high-risk patients receiving care management per primary care physician (91 patients and 48%, P =.036 and P =.128, respectively). CPC practices used 4 primary methods to identify high-risk patients. Although practices that developed their own algorithm identified the greatest number of high-risk patients, practices that used clinical intuition connected the greatest proportion of patients to care management services. © 2017 Annals of Family Medicine, Inc.

    Full Text Available The photocatalytic degradation of indigo carmine (IC dye in the presence of titanium dioxide under different conditions was reported. Several factors which interfere with the photodegradation efficiency as catalyst concentration, pH, initial concentration of dye, presence of inorganic anions, temperature, and the addition of hydrogen peroxide were studied under artificial irradiation with a 125 W mercury vapor lamp. Additionally, the catalyst supported on glass spheres was used for the photocatalytic degradation of the dye present in several types of waters in a CPC solar pilot plant. The photocatalytic products, carboxylic acids, and SO42- and NH4+ were followed during IC mineralization. Formate, acetate, and oxalate were detected in real MWWTP secondary effluent. The mineralization efficiency was of 42 and 21% using in suspension and supported TiO2, respectively. In order to evaluate biological effects, Eisenia andrei earthworms were used as a model organism. No significant difference (P>0.05 of weight was observed in the earthworm submitted to different concentrations of IC and its photoproducts. The photocatalytic degradation of IC on TiO2 supported on glass spheres suffered strong influence of the water matrix; nevertheless the method has the enormous advantage that it eliminates the need for the final catalyst removal step, reducing therefore the cost of treatment.

    This paper is mainly aiming to prove that the stripy noises in the map of earth's surface mass-density changes derived from GRACE Satellites gravimetry, is due to a dissatisfaction of Compact Picard Condition (CPC) with the GRACE data in the inversion of the Newton Integral Equation over the thin layer of earth; and hence the paper proposes the regularization strategies as efficient tools to treat the Ill-posedness and consequently to de-strip the data. First of all, we preferred to slightly modify the mathematical model of earth's surface mass-density changes developed creatively first by J. Wahr and et.al (1998), according to the all their previous assumptions plus taking into consideration the effect of the earth topography. By the modification we expect that some uncertainties in the prior model have been reduced to some extent. Then we analyzed the CPC on the model and we demonstrated how to perform Generalized Tikhonov regularization in Sobolev subspace for overcoming the instability of the problem. Then we applied the strategy in some simulations and case studies to validate our ideas. The simulations confirm that the stripy noises in the GRACE-derived map of the mass-density changes are due to the CPC dissatisfaction and furthermore the case studies show that Generalized Tikhonov regularization in Sobolev subspace is an influential filtering tool to de-strip the noisy data. Also, the case studies interestingly show that the effect of the topography is comparable to the effect of the load Love numbers on the Wahr's model; hence it may be taken into consideration when the load Love numbers have been taken into account.

    Several groups have defined pancreatic surgery quality metrics that identify centers delivering quality care. Although these metrics are perceived to be associated with good outcomes, their relationship with actual outcomes has not been established. A national cadre of pancreatic surgeons was surveyed regarding perceived quality metrics, which were evaluated against the Central Pancreas Consortium (CPC) database to determine actual performance and relationships with long-term outcomes. The most important metrics were perceived to be participation in clinical trials, appropriate clinical staging, perioperative mortality, and documentation of receipt of adjuvant therapy. Subsequent analysis of 1399 patients in the CPC dataset demonstrated that a R0 retroperitoneal and neck margin was obtained in 79% (n = 1109) and 91.4% (n = 1278) of cases, respectively. 74% of patients (n = 1041) had >10 lymph nodes harvested, and LN positivity was 65% (n = 903). 76% (n = 960) of eligible patients (surgery first approach) received adjuvant therapy within 60 days of surgery. Multivariate analysis demonstrated margin status, identification of >10 lymph nodes, nodal status, tumor grade and delivery of adjuvant therapy within 60 days to be associated with improved overall survival. These analyses demonstrate that systematic monitoring of surgeons' perceived quality metrics provides critical prognostic information, which is associated with patient survival.

    Phycocyanin is an important component of the phycobilisome, which is the principal light-harvesting complex in cyanobacteria. The covalent attachment of the phycocyanobilin chromophore to phycocyanin is catalyzed by the enzyme phycocyanin lyase. The photosynthetic properties and phycobilisome assembly state were characterized in wild type and two mutants which lack holo-α-phycocyanin. Insertional inactivation of the phycocyanin α-subunit lyase (ΔcpcF mutant) prevents the ligation of phycocyanobilin to α-phycocyanin (CpcA), while disruption of the cpcB/A/C2/C1 operon in the CK mutant prevents synthesis of both apo-α-phycocyanin (apo-CpcA) and apo-β-phycocyanin (apo-CpcB). Both mutants exhibited similar light saturation curves under white actinic light illumination conditions, indicating the phycobilisomes in the ΔcpcF mutant are not fully functional in excitation energy transfer. Under red actinic light illumination, wild type and both phycocyanin mutant strains exhibited similar light saturation characteristics. This indicates that all three strains contain functional allophycocyanin cores associated with their phycobilisomes. Analysis of the phycobilisome content of these strains indicated that, as expected, wild type exhibited normal phycobilisome assembly and the CK mutant assembled only the allophycocyanin core. However, the ΔcpcF mutant assembled phycobilisomes which, while much larger than the allophycocyanin core observed in the CK mutant, were significantly smaller than phycobilisomes observed in wild type. Interestingly, the phycobilisomes from the ΔcpcF mutant contained holo-CpcB and apo-CpcA. Additionally, we found that the large form of FNR (FNR(L)) accumulated to normal levels in wild type and the ΔcpcF mutant. In the CK mutant, however, significantly less FNR(L) accumulated. FNRL has been reported to associate with the phycocyanin rods in phycobilisomes via its N-terminal domain, which shares sequence homology with a phycocyanin linker

    To evaluate the clinical efficacy of a mouthwash containing 0.075% cetylpyridinium chloride (CPC) in a fluoride-free, alcohol-free base and a mouthwash containing essential oils in a fluoride-free, 21.6% alcohol base as compared to a fluoride-free, alcohol-free non-antibacterial mouthwash in controlling established dental plaque and gingivitis after 6 weeks of twice daily use. A 6-week, parallel-group, randomized double blind clinical trial was conducted in Santo Domingo, Dominican Republic. Recruited subjects were randomly assigned to one of three treatment groups: (1) a mouthwash containing 0.075% CPC in a fluoride-free, alcohol-free base (CPC); (2) a commercially-available mouthwash containing essential oils in a fluoride-free, 21.6% alcohol base (EO); or (3) a fluoride-free, alcohol-free non-antibacterial mouthwash (NC). Subjects were instructed to rinse with the assigned mouthwash, after tooth brushing, twice daily (morning and evening). After 4 and 6 weeks of product use, subjects were examined for gingivitis (Whole Mouth Gingival, Gingival Interproximal, Gingival Severity Indexes) and plaque (Whole Mouth Plaque, Plaque Interproximal, and Plaque Severity Indexes) parameters. For treatment group comparisons, ANCOVA and post hoc Tukey's pair-wise comparisons (α = 0.05) were performed. 132 subjects were screened; 120 were enrolled; and 116 completed the study. After 6 weeks of product use, subjects using the CPC and EO mouthwashes exhibited statistically significant (P plaque measurements compared to subjects using the NC mouthwash. Subjects using the CPC mouthwash did not exhibit a statistically significant (P > 0.05) reduction with respect to gingival severity and all plaque measures (Whole, Interproximal, and Severity) when compared to EO mouthwash. Subjects using the CPC mouthwash exhibited statistically significant (P < 0.05) reductions in Gingival Index scores of 5.1% (P = 0.005), and Gingival Interproximal Index scores of 5.5% (P = 0.016) relative to

    To overcome the problem that the heat source temperature is limited and the lower part of the adsorption tube cannot effectively absorb the solar radiation when solar radiation as the heat source of the adsorption refrigeration system. From the perspective of enhancing the adsorption refrigeration unit tube to absorb solar radiation, thereby strengthening the heat transfer characteristic of adsorption bed, which can improve the efficiency of the refrigeration unit refrigerating capacity and system refrigeration efficiency. Solar adsorption refrigeration system based on CPC was designed and constructed in this paper. The heat and mass transfer performance of the adsorption refrigeration system were studied. The experimental results show that the temperature of the adsorption bed with parabolic concentrating structure can rise to 100°C under low irradiation condition. When the irradiation intensity is 600 w/m2 and 400 w/m2, the average temperature rising to desorption temperature reaches 0.67°C and 0.50°C, respectively. It can effectively solve the problem that the conventional adsorption bed is difficult to reach the required desorption temperature due to the low power density of the sunlight. In the experiment, the system COP were 0.166 and 0.143 when the system in the irradiance of 600 w/m2 and 400 w/m2.

    Full Text Available Compound parabolic concentrators are relevant systems used in solar thermal technology. With adequate tailoring, they can be used as an efficient and low-cost alternative in residential water heating applications. This work presents a simulation study using a ray tracing analysis. With this technique, we simulate the interaction between solar rays and solar concentrator to quantify the amount of energy that impinges on the receiver at a particular time. Energy availability is evaluated in a comparison of two configurations throughout the year: static setup at 21° and multi-position setup; tilted with respect to the horizontal, depending on three seasonal positions: 0° for summer, 16° for spring/autumn, and 32° for winter, with the aim to evaluate the amount of available energy in each season. The fact that a tracking system can be dispensed with also represents an economical option for the proposed application. The results showed that at 21°, the proposed solar Compound Parabolic Concentrator (CPC works satisfactorily; however, by carrying out the selected angular adjustments, the overall energy availability increased by 22%, resulting in a more efficient option. The most effective design was also built and analyzed outdoors. The obtained thermal efficiency was of ~43%. The optical design and its evaluation developed herein proved to be a valuable tool for prototype design and performance evaluation.

    To assess problematic sexually explicit media (SEM) consumption, and to identify clinically meaningful cut-off points, we examined clinical correlates using the new Compulsive Pornography Consumption (CPC) scale among 1165 participating MSM. Building on scale practices in measuring compulsive sexual behavior, two cut-off points were identified. While most (76-80%) MSM do not report compulsive symptoms, about 16-20% report levels of problematic SEM consumption, including 7% with extreme scores consistent with DSM criteria for compulsive disorders. Demographic, sexual, and HIV risk differences were identified between the three groups. Researchers and clinicians are encouraged to consider using the CPC scale for comprehensive assessment of compulsive sexual behavior. PMID:26167109

    To determine the relationships between partial pressure of arterial carbon dioxide (PaCO2), prescribed minute ventilation (MV), and neurologic outcome in patients resuscitated from cardiac arrest. This was a retrospective cohort study utilizing a multicenter database of adult patients with return of spontaneous circulation (ROSC) after cardiac arrest. The primary outcome was neurologic status at hospital discharge, defined by Cerebral Performance Category (CPC) score: CPC 1-2 was favorable, CPC 3-5 was poor. We compared rates of initial normocarbia (PaCO2 31-49mmHg) and mean sequential PaCO2 measurements obtained over the first 24h. We also assessed the influence of MV on the PaCO2 at initial, 6, 12, 18, and 24h after cardiac arrest using univariate linear regression. One hundred and fourteen patients from 3 institutions met inclusion criteria. Overall, 46/114 (40.4%, 95% CI: 31.4-49.4%) patients survived to hospital discharge, and 33/114 (28.9%, 20.6-37.2%) had CPC 1-2 at the time of discharge. A total of 38.9% (95% CI: 29.9-47.9%) of patients had initial normocarbia; 43.2% (28.6-57.8%) of these patients were discharged with CPC 1-2, compared with 20.3% (10.8-29.8%) of dyscarbic patients. By 6h, neurologic outcomes were not significantly associated with PaCO2. Prescribed MV was not associated with PaCO2 at any time point with the exception of a weak correlation at hour 18. Initial normocarbia was associated with favorable neurological outcome in patients resuscitated from cardiac arrest. This relationship was not seen at subsequent time points. There was no significant association between prescribed MV and PaCO2 or neurologic outcome. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available TiO2 immobilized on polyethylene (PET nonwoven sheet was used in the solar photocatalytic degradation of methylene blue (MB. TiO2 Evonik Aeroxide P25 was used in this study. The amount of loaded TiO2 on PET was approximately 24%. Immobilization of TiO2 on PET was conducted by dip coating process followed by exposing to mild heat and pressure. TiO2/PET sheets were wrapped on removable Teflon rods inside home-made bench-scale recirculating flow Compound Parabolic Concentrator (CPC photoreactor prototype (platform 0.7 × 0.2 × 0.4 m3. CPC photoreactor is made up of seven low iron borosilicate glass tubes connected in series. CPC reflectors are made of stainless steel 304. The prototype was mounted on a platform tilted at 30°N local latitude in Cairo. A centrifugal pump was used to circulate water containing methylene blue (MB dye inside the glass tubes. Efficient photocatalytic degradation of MB using TiO2/PET was achieved upon the exposure to direct sunlight. Chemical oxygen demand (COD analyses reveal the complete mineralization of MB. Durability of TiO2/PET composite was also tested under sunlight irradiation. Results indicate only 6% reduction in the amount of TiO2 after seven cycles. No significant change was observed for the physicochemical characteristics of TiO2/PET after the successive irradiation processes.

    A novel method with high sensitivity was designed for the determination of trace nucleic acids by using cationic surfactant cetylpyridinium chloride (CPC) and camellia sinensis (CS) as resonance Rayleigh light scattering (RLS) probes. It was found DNA could combine with CS and CPC in Tris-HCl buffer (pH = 7.4). Under optimum conditions, the RLS intensity of DNA can be enhanced by CPC-CS obviously at 294 nm, and the enhanced RLS intensity was directly proportional to DNA concentration in the range from 0.024 to 3.48 μg mL-1 with a good linear relationship (r = 0.9940). The limit of detection (LOD) was 1.49 ng mL-1 (S/N = 3). In addition, the effects of some interferences including K+, Na+, Mg2+, Zn2+, Cu2+, Ca2+ and glucose on the determination were studied. The developed RLS assay was successfully applied to three synthetic samples to measure DNA, the recovery was 94.7-106.3% and RSD was 0.58-3.33%.

    Full Text Available El objetivo de la pesquisa fue trazar un panorama de la divulgación de segmentos en las demostraciones financieras de las compañías abiertas que operan en el Brasil, publicadas en 2010, primer año de vigencia del CPC 22. Para eso se procuró identificar cómo fueron definidos y cuántos son los segmentos publicados, además de analizar tales resultados en relación a características corporativas de la empresa: tamaño, sector de actuación y status de listado de la compañía en los niveles de gobernanza corporativa. Se trata de pesquisa bibliográfica y documental con foco descriptivo. El análisis de los datos fue realizado en notas explicativas de 81 compañías abiertas seleccionadas entre las mayores empresas, en la edición 2010 de la Revista Melhores e Maiores (Mejores y Mayores. El análisis de los datos fue realizado con estadística descriptiva y análisis de correlación. Los resultados de la pesquisa mostraron que hay empresas que no hicieron ninguna referencia a informaciones por segmentos. La definición de los segmentos atendió predominantemente al criterio de línea de negocios, y el 27% de las compañías agruparon las actividades en un único segmento. El análisis de la correlación mostró que solamente el tamaño del activo presentó relacionamiento significante y positivo con las características de definición y cantidad de segmentos publicados. Fue constatado que hay gran heterogeneidad en las estructuras de los informes por segmento publicados.

    Although the phenomenon of hypersexuality has been described in the literature, and scales of compulsive sexual behavior have been published, the existing measures do not assess compulsive sexually explicit media (SEM) consumption. This study tested the psychometric properties of a new scale, the Compulsive Pornography Consumption (CPC). Exploratory and confirmatory factor analyses results showed good psychometric performance of a five item two factor preoccupation-compulsivity solution. As hypothesized, the scale correlates positively with compulsive sexual behavior, internalized homonegativity, and negatively with sexual self-esteem. The scale will enable researchers to investigate the etiologic factors of compulsive SEM use, and enable clinicians to assess problematic consumption. PMID:25838755

    Water samples of 0, 5, and 30 nephelometric turbidity units (NTU) spiked with Cryptosporidium parvum oocysts were exposed to natural sunlight using a 25-L static solar reactor fitted with a compound parabolic collector (CPC). The global oocyst viability was calculated by the evaluation of the inclusion/exclusion of the fluorogenic vital dye propidium iodide and the spontaneous excystation. After an exposure time of 8 hours, the global oocyst viabilities were 21.8 ± 3.1%, 31.3 ± 12.9%, and 45.0 ± 10.0% for turbidity levels of 0, 5, and 30 NTU, respectively, and these values were significantly lower (P 10 times).

    To study the assembly of phycocyanin β subunit, the gene cpcT was first cloned from Arthrospira platensis FACHB314. To explore the function of cpcT, the DNA of phycocyanin β subunit and cpcT were transformed into Escherichia coli BL21 with the plasmid pET-hox1-pcyA, which contained the genes hemeoxygenase 1 (Hox1) and ferredoxin oxidoreductase (PcyA) needed to produce phycocyanobilin. The transformed strains showed specific phycocyanin fluorescence, and the fluorescence intensity was stronger than the strains with only phycocyanin β subunit, indicating that CpcT can promote the assembly of phycocyanin to generate fluorescence. To study the possible binding sites of apo-phycocyanin and phycocyanobilin, the Cys-82 and Cys-153 of the β subunit were individually mutated, giving two kinds of mutants. The results show that Cys-153 maybe the active site for β subunit binding to phycocyanobilins, which is catalyzed by CpcT in A. platensis FACHB314. Copyright © 2014 Elsevier B.V.

O estudo caracteriza-se como descritivo, conduzido por meio de análise documental e abordagem quantitativa. A população é composta de 109 empresas em 2011, abrangendo uma amostra de 106 empresas. Para coleta dos dados foi elaborado um check list composto de 17 itens baseados no Pronunciamento Técnico CPC 27. A técnica de análise, buscando alcançar a proposta de pesquisa, deu-se por meio de regressão linear múltipla. Nos resultados encontrados, verificou-se uma relação positiva significativa entre o ativo imobilizado das empresa e o índice de evidenciação, verificado pelos itens correspondentes aos requisitos mencionados no CPC 27. No que tange às variáveis determinantes do processo de evidenciação, verificou-se que “Imobilizado” está positivamente associado à divulgação de informações sobre ativo imobilizado. Já a “Rentabilidade” está negativamente associada à divulgação. Não se verificou associação significante entre “Endividamento” e “Tamanho” com a divulgação de informações sobre imobilizado. É necessário considerar, ainda, o baixo fator explicativo das variáveis determinantes da evidenciação recomendada pelo CPC 27 e a necessidade de se estender a investigação dentro do tema, possibilitando comparações e extração de novas evidências conclusivas.

    Brazilian cherry seeds are a waste product from juice and frozen pulp production and, the seeds composition was investigated to valorize this by-product. Compounds separation was performed with ethanol by pressurised fluid extraction (PFE). Here we determine the effect of temperature (T), static time (ST), number of cycles (C), and flush volume (VF) on the yield, composition and total phenolic content (TPC) of the seed extracts. T, ST and their interaction positively influenced yield and TPC. Extracts were fractionated by high performance liquid chromatography (HPLC) and centrifugal partition chromatography (CPC). The collected fractions characterizations were made by electrospray ionisation mass spectrometry (ESI/MS) and high resolution mass spectrometry (HRMS) indicated the presence of ellagic acid pentoside and deoxyhexose, quercitrin and kaempferol pentoside. All of these compounds have antioxidant properties and normally are found in plant extracts. These results confirm that Brazilian cherry seed extract is a potentially valuable source of antioxidants.

    Full Text Available A CPC (Compound Parabolic Concentrator reactor was projected and constructed aiming to promote the degradation of the organic matter present in considerable volumes of aqueous effluents, under the action of solar radiation. The essays were done using a model effluent which consists of a mixture of fragments of a sodium salt of lignosulphonic acid possessing a mean molecular weigth of 52,000 Daltons, and a real effluent, from a chip board industry. The volume of effluent in each test was about 50 L. The tests involved heterogeneous (TiO2 P25 Degussa and formulations made from the association of TiO2 with a photosensitiser, and homogeneous (thermal and photochemical Fenton reactions catalysis of the effluents. The results demonstrate the viability of application of this kind of reactor even when the load of organic pollutants is high.

MÉTODOS: Foram utilizados 137 ratos "Wistar", machos, subnutridos pela oferta de 33% da ingestão diária normal na fase de adaptação e durante o experimento, distribuídos por sorteio, em 9 grupos experimentais, submetidos a três tratamentos (Controle, Toracotomia, Trilobectomia e sacrificados em três momentos (7, 30 e 90 dias. Na Trilobectomia foram extirpados os lobos médio, acessório e caudal direitos, que representavam 55% do tecido pulmonar. Estudou-se os seguintes atributos e variáveis: massa corpórea e pulmonar, relação entre massa pulmonar e corpórea e conteúdos protéicos pulmonares. RESULTADOS: No lobo cranial e no pulmão esquerdo, tanto a massa quanto os conteúdos protéicos, nos trilobectomizados, foram maiores em todos os momentos do estudo quando comparados aos demais, sendo este aumento suficiente para compensar a perda dos três lobos. Os conteúdos protéicos do lobo cranial e do pulmão esquerdo, nos trilobectomizados, tiveram o mesmo comportamento da massa pulmonar, mas este aumento não foi suficiente para compensar a perda dos três lobos. CONCLUSÕES: Nos ratos adultos subnutridos trilobectomizados ocorre CPC. A recuperação da massa pulmonar é total, mas o conteúdo protéico pulmonar apesar de aumentar, não chega aos valores dos ratos não trilobectomizados.

    Spirulina platensis :have been studied for several biological activities. In the current study C-phycocyanin containing protein extract (C-PC extract) of Spirulina platensis have been studied for its effect on human matrix metalloproteinases (MMP-1, MMP-2 and MMP-9) and tissue inhibitors of MMPs (TIMP-1 and TIMP-2). In the present study, breast cancer cell line (MDA-MB 231) and hepatocellular cancer cell line (HepG2) were examined for inhibition of MMPs at different levels of expression after C-PC extract treatment. Herein, we have demonstrated that C-PC extract significantly reduced activity of MMP-2 by 55.13% and MMP-9 by 57.9% in HepG2 cells at 15 μg concentration. Additionally, the treatment has reduced mRNA expression of MMP-2 and MMP-9 at 20 μg concentration by 1.65-folds and 1.66-folds respectively. The C-PC extract treatment have also downregulated a mRNA expression of TIMP-2 by 1.12 folds at 20 μg concentration in HepG2 cells. Together, these results indicate that C-PC, extract successfully inhibited MMP-2 and -9 at different levels of expression and TIMP-2 at a mRNA expression level; however, extract did not have any effect on MMP-1 expressed in MDA-MB231 and TIMP-1 expressed in HepG2 cells as well as the exact mechanism of inhibition of MMP-2, MMP-9 and TIMP-2 remained unclear.

    To evaluate the clinical efficacy of two commercially available, fluoride-free, alcohol-free mouthwashes containing either 0.075% or 0.07% cetylpyridinium chloride (CPC) in controlling established dental plaque and gingivitis compared to a non-antibacterial control mouthwash. A 6-week double-blind, randomized clinical trial was conducted in Trujillo Alto, Puerto Rico. Recruited subjects were randomly assigned to one of three treatment groups: (1) a fluoride-free, alcohol-free mouthwash containing 0.075% CPC (TG); (2) a fluoride-free, alcohol-free mouthwash containing 0.07% CPC (PC); and (3) a fluoride-free, alcohol-free mouthwash without antibacterial agent (NC). Subjects were instructed to rinse with the assigned mouthwash, after tooth brushing, twice daily (morning and evening). After 4 and 6 weeks of product use, subjects were examined for gingivitis (Whole Mouth Gingival, Gingival Interproximal, Gingival Severity Indexes) and plaque (Whole Mouth Plaque, Plaque Interproximal, and Plaque Severity Indexes) parameters. ANCOVA and post hoc Tukey's pair-wise comparisons (α = 0.05) were performed for treatment group comparisons. A total of 132 subjects were screened; 120 were enrolled; and 116 completed the study. After 6 weeks of product use, participants who rinsed with the CPC-containing mouthwashes exhibited statistically significant (P plaque parameters evaluated, whereas in those using the non-antibacterial mouthwash, significant reductions were only observed in whole mouth and interproximal plaque scores. No statistically significant (P > 0.05) differences were observed, with respect to the gingival and plaque parameters, between the two CPC-containing mouthwashes.

The viscosities were fitted in extended Jones–Doles equation for intrinsic viscosity (B, kg mol−1 and slope (D, kg mol−12 derivation. The γ and Vϕ data were regressed for their limiting γ0 andVϕ0 data and the SEMs were illustrated surface morphology. The EPC caused maximum oil–water dissolution as compared to other surfactants. Intramolecular multiple force theory [IMMFT] is proposed to explain molecular interactions of olive oil–water–EPC mixtures with a possible correlation of surface and bulk reorientations with microstructures depicted with SEM. Frictional and cohesive forces as Friccohesity have been noted as driving forces to assert for validity of the IMMFT model and its link with SEM.

    Full Text Available The aim in this research was to outline a panorama of segment disclosure in the financial statements of publicly traded companies active in Brazil, which were published in 2010, the first year in force of CPC 22. Therefore, the researchers attempted to identify how the segments were defined and how many were published, besides analyzing these results with regard to the company’s corporate characteristics: size, activity sector and listing status according to corporate governance levels. A bibliographic and descriptive study with a descriptive focus was undertaken. The data were surveyed in the notes to the financial statements of 81 publicly traded companies, selected among the largest companies in the 2010 edition of Revista Melhores e Maiores. Data analysis was based on descriptive statistics and correlation analysis. The research results showed that some companies did not refer in any way to segment information. The definition of the segments mainly followed the criterion of the business line, and 27% of the companies grouped the activities in a single segment. The correlation analysis showed that only the asset size showed a significant and positive relation with the characteristics of the definition and the number of segments published. Great heterogeneity was found in the structure of the segment reports published.

    Full Text Available This paper aimed to investigate information disclosure on business combination transactions that took place in Brazil in 2010, when the Accounting Standard CPC 15 entered into force, and evaluate which were the determining factors of the level of disclosure of information related to it. To evaluate the disclosure level, a disclosure index of business combinations (INDCOMB was prepared, having the disclosure index developed by Shalev (2009 as a basis. We evaluated, in the light of the literature on disclosure and business combinations, whether the following factors influenced on the disclosure level: acquiring company size, recognized percentage of overprice for expected future profitability in relation to the transaction value, dispersion of capital of the acquiring company, audit firm size, and participation of the acquiring company in American Depositary Receipts (ADRs programs. The control variables used were listing of the acquiring company in the various segments of BM&FBOVESPA, operation sector, origin (state, private company with national capital or private company with foreign capital, and relative acquired company size in relation to the acquiring company. We analyzed business combination transactions that took place in 2010, reported by 40 open capital companies involved in 76 transactions. We conclude that the audit firm size and the relative acquired company size were factors that influenced on the level of disclosure of information regarding business combinations in 2010. The other factors showed no conclusive results.

    Full Text Available The escalating occurrence of cyanobacterial toxic blooms demands a better understanding of genetic variability as an auxiliary expedient in species identification, collaborating with the monitoring of water destined to public supply. This study aimed at the unraveling of genetic polymorphism in the toxic and nontoxic strains of Microcystis (Cyanobacteria species, isolated from diverse Brazilian localities through the RFLP-PCR technique applied to the c-phycocyanin encoding operon and its intergenic spacer (cpcBA-IGS. Eighteen strains belonging to M. aeruginosa, M. panniformis, M. protocystis and M. wesenbergii, plus two other unidentified strains, were analyzed by means of the morphological and molecular data. The molecular data constituted three groups with low similarity values unrelated to the geographical origin, toxicity or morphospecies. A high genetic variability among the studied populations was unveiled by the results. Brazilian populations of Microcystis spp. displayed high genetic diversity when compared to those from Australia, Japan, United States and Europe. This ample genetic diversity could be observed through the diverse eletrophoretic profiles obtained among the strains from a single species. The presence of toxic and non-toxic strains was observed in the same species, as M. aeruginosa.A ocorrência de florações de cianobactérias tóxicas demanda um melhor entendimento da variabilidade genética como um instrumento auxiliar na identificação de espécies colaborando, assim, com o monitoramento de águas destinadas ao abastecimento público.

    Full Text Available O desenvolvimento do Brasil, como nação autônoma, teve seu marco inicial após sua independência de Portugal, em 1822. Diante do cenário de nascimento e evolução da sociedade brasileira, este trabalho apresenta uma pesquisa cronológica sobre a normatização das demonstrações contábeis, especialmente focada no Balanço Patrimonial (BP. Esse estudo caracteriza-se essencialmente por ser uma pesquisa bibliográfica histórica. A primeira normatização contábil brasileira ocorreu com a publicação do 1º Código Comercial Brasileiro (CCB em 26/06/1850, através da Lei nº 556. Dez anos após o CCB, entrou em vigência a Lei nº 1.083 de 22/08/1860, conhecida como “a primeira Lei das S. A. no Brasil”. O Brasil passou a ter uma Lei das S.A. atualizada, com a publicação da Lei 2.627. Em 1976, o Brasil incorpora as tendências contábeis Norte-Americanas com a nova Lei das S.A.: Lei nº 6.404 de 15/12/1976. A primeira grande alteração dessa Lei ocorreu em 2007, com a Lei no 11.638, de 28/12/2007 a Deliberação CVM 488 de 03/10/2005, contudo, já estabelecia o início do processo de convergência para a adoção dos princípios internacionais. A partir da publicação do CPC1, seguiram-se outros que reestruturaram a Contabilidade Brasileira. Dentre esses Pronunciamentos, o CPC 26 apresenta a estrutura das demonstrações contábeis em correlação às Normas Internacionais de Contabilidade – IAS 1. Constata-se que durante esse período de mais de um século e meio, especialmente analisando-se o BP, a Contabilidade Brasileira sempre buscou um caminho de atualização e vinculação mundial.The development of Brazil, as autonomous nation, had its starting point after its independence from Portugal in 1822.

    Full Text Available The article brings up the artistic and political participation of film director Carlos Diegues in two important cultural movements for Brazilian cultural life: Popular Center Culture (CPC and New Cinema. Both are so much emblematic from engaged art in early 1960s and allowing a deeper debate about the social role of artist and social struggles that preceded the military coup. Thus, in addressing his career of the director Carlos Diegues and his militant role in this context, we seek understand and contribute to historical production about the recent history of Brazil.

    Cotton (Gossypium hirsutum L.) fibers are trichomes that initiate from the ovule epidermis. Little is known about the developmental pathway causing fiber to differentiate from ovular epidermal cells even though limits on the number of cells that differentiate into fiber will limit yield. A method was developed to isolate RNA from fiber initials 1 day post anthesis (dpa). Complementary DNA libraries representing 1 dpa fibers and other cotton tissues were sequenced and analyzed. Assembly of G. hirsutum Expressed Sequenced Tags (ESTs) identified over 11,000 sequences not previously represented in GenBank. New genes identified among these ESTs were represented on microarrays. The microarrays were used to identify genes enriched in fiber initials (1 dpa fibers) and elongating fibers. Analyses of Gene Ontologies (GO) of differentially expressed genes determined that terms associated with the "membranes" were statistically over represented among genes increased in expression in fiber initials and 10 dpa fibers. Staining ovules with a fluorescent dye confirmed an increase in Endoplasmic Reticulum (ER) occurred in fiber initials on the day of anthesis, persisted through 3 dpa and was absent in a fiberless mutant. Two genes similar to the CAPRICE/TRIPTYCHON (CPC) gene that inhibits differentiation of leaf trichomes in Arabidopsis were also characterized. Genes associated with novel regulation of brassinosterols, GTP mediated signal transduction and cell cycle control and components of a Ca+2 mediated signaling pathway were identified. Staining of cellular Ca+2 indicated that fiber initials had more Ca+2 than other ovule cells supporting a role for Ca+2 in fiber development. Analysis of genes expressed in fiber initials identified a unique stage in fiber development characterized by an increase in ER and Ca+2 levels that occurred between 0 and 1 dpa. The gene similar to CPC has a MYB domain but appears to lack a transcription activating domain similar to the Arabisopsis gene

    To assess the anti-plaque efficacy of an oral hygiene regimen comprised of a stannous-containing sodium fluoride dentifrice, advanced manual toothbrush, and a cetylpyridinium chloride (CPC) rinse compared to a negative control regimen. This was a 4-week randomized and controlled, parallel group, single-center, single- blind, clinical trial in generally healthy Chinese adults with existing dental plaque. Following a 1-week acclimation period and cessation of overnight oral hygiene prior to the baseline examination, overnight pre-brushing plaque levels were assessed via digital plaque imaging analysis (DPIA). Subjects were randomly assigned to either: (1) the test regimen of a stannous-containing sodium fluoride dentifrice (Crest Pro-Health Expert), an advanced manual toothbrush with CrissCross bristles (Crest Pro-Health manual toothbrush), and a 0.07% CPC rinse (Crest Pro-Health Multi-Protection); or (2) the negative control regimen group, a 0.243% sodium fluoride dentifrice (Crest Cavity Protection) and a soft flat trim manual toothbrush (Crest MeiLiLiangJie). Subjects returned at Week 2 and Week 4 following twice daily use of their assigned products, again following pre-visit cessation of overnight oral hygiene, for DPIA evaluation of overnight plaque levels. 35 fully evaluable subjects completed the trial. At Week 2, the pre-brushing overnight average DPIA plaque scores for the advanced products regimen group were 72.4% statistically significantly lower relative to the control group (Pplaque inhibition benefit provided by the regimen group was 76.8% greater than the control group (P< 0.0001). All products were well-tolerated. (Am J Dent 2016;29:120-124)

    Antimonato polyoxovanadate (POV) cluster compounds {M(en)3}3[V15Sb6O42(H2O)x]·nH2O (M = FeII, CoII, NiII and x = 0 or 1) obtained under solvothermal conditions exhibit unusual high water solubility making these compounds promising synthons for generation of new POV structure types. Electrospray ionization mass spectrometry provides evidence (i) for a water molecule encapsulated inside the cavity of a fraction of the spherical cluster shells, (ii) for a post-functionalization in water, namely a slow exchange of VO against Sb2O, (iii) for the inner-phase reactivity of the encapsulated water that is capable of opening an oxo-bridge, and (iv) for a significant acceleration of the 16O/18O exchange reactions of oxygen atoms in the cluster periphery with surrounding H2 18O, when encapsulated water is present. To the best of our knowledge, this is the first example in polyoxovanadate chemistry for the transduction of inner-phase reactivity of an encapsulated guest molecule into changes in the outer-phase reactivity of the cluster. Magnetic susceptibility measurements reflect the individual contributions of the frustrated {V15} spin polytope and the {M(en)3}2+ complexes, with very weak coupling between these groups.

    Although antinuclear campaigns seem to be effective, public communication and education efforts on low-level radioactive waste have mixed results. Attempts at public information programs on low-level radioactive waste still focus on influencing public opinion. A question then is: {open_quotes}Is it preferable to have a program focus on public education that will empower individuals to make informed decisions rather than trying to influence them in their decisions?{close_quotes} To address this question, a case study with both quantitative and qualitative data will be used. The Ohio Low-Level Radioactive Waste Education Program has a goal to provide people with information they want/need to make their own decisions. The program initiated its efforts by conducting a statewide survey to determine information needed by people and where they turned for that information. This presentation reports data from the survey and then explores the program development process in which programs were designed and presented using the information. Pre and post data from the programs reveal attitude and knowledge shifts.

    The U.S. Department of Energy (DOE) is launching a major research and development initiative to create a small, fast, inexpensive and environmentally friendly rig for drilling 5000 feet boreholes to investigate potential oil and gas reservoirs. DOE wishes to get input from petroleum industry operators, service companies and equipment suppliers on the operation and application of this coiled-tubing-based drilling unit. To that end, DOE has asked Spears & Associates, Inc. (SAI) to prepare a special state-of-the-market report and assist during a DOE-sponsored project-scoping workshop in Albuquerque near the end of April 2003. The scope of the project is four-fold: (1) Evaluate the history, status and future of demand for very small bore-hole drilling; (2) Measure the market for coiled tubing drilling and describe the state-of-the-art; (3) Identify companies and individuals who should have an interest in micro drilling and invite them to the DOE workshop; and (4) Participate in 3 concurrent workshop sessions, record and evaluate participant comments and report workshop conclusions.

    The use of nomograms which include the PSA may improve the predictive power of obtaining a prostate biopsy (PB) positive for cancer. We compare the use of three on-line nomagrams with the detection of primary malignant circulating prostate cells (CPCs) to predict the results of an initial PB in men with suspicion of prostate cancer. Consecutive men with suspicion of prostate cancer underwent a 12 core TRUS prostate biopsy; age, total serum PSA, percent free PSA, family history, ethnic origin and prostate ultrasound results were used for risk assessment using the online nomograms. Mononuclear cells were obtained by differential gel centrifugation from 8ml of blood and CPCs were identified using double immunomarcation with anti-PSA and anti-P504S. A CPC was defined as a cell expressing PSA and P504S and defined as negative/positive. Biopsies were classified as cancer/no-cancer. Areas under the curve (AUC) for each parameter were calculated and compared and diagnostic yields were calculated. 1,223 men aged>55 years participated, 467 (38.2%) had a biopsy positive for cancer of whom 114/467 (24.4%) complied with the criteria for active observation. Area under the curve analysis showed CPC detection to be superior (p<0.001), avoiding 57% of potential biopsies while missing 4% of clinically significant prostate cancers. The CPC detection was superior to the nomograms in predicting the presence of prostate cancer at initial biopsy; its high negative predictive value potentially reduces the number of biopsies while missing few significant cancers, being superior to the nomograms in this aspect. Being a positive/negative test the detection of CPCs avoids defining a cutoff value which may differ between populations. Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U.

    Little is known about the role of time to initiation of therapeutic hypothermia and time to target temperature (TTT) in the prognosis of patients resuscitated from cardiac arrest. A retrospective analysis was performed in 145 survivors of cardiac arrest who underwent therapeutic hypothermia between January 2003 and January 2013. The objective was to identify predictors of survival free from significant neurological sequelae (Cerebral Performance Categories Scale (CPC): >2) six months after cardiac arrest. We evaluated the effect of faster and earlier cooling. Overall survival at six months was 42.1% (61 patients); 59 of these were considered to have a good neurological status (CPC ≤ 2), and in whom therapeutic hypothermia was initiated earlier (87 ± 17 min vs. 111 ± 14 min; p=0.042), and the target temperature was reached at an earlier time (TTT: 316 ± 30 min vs. 365 ± 27 min; p=0.017). Multivariate analysis selected longer duration of cardiac arrest (odds ratio (OR) = 1.06 per min), a non-shockable initial rhythm (OR=13.8), severe acidosis (OR=0.009 per 0.01 unit), older age (OR=1.04 per year) and longer TTT (OR=1.005 per min) as associated with poor prognosis. The most important prognostic factors for death or lack of neurological recovery in patients with cardiac arrest treated with therapeutic hypothermia are initial-rhythm, time from cardiac arrest to return of spontaneous circulation and arterial-pH at admission. Although the speed of cooling initiation and the time to reach target temperature may play a role, its influence on prognosis seems to be less important. © The European Society of Cardiology 2014.

  18. Salt shock-inducible photosystem I cyclic electron transfer in Synechocystis PCC6803 relies on binding of ferredoxin:NADP(+) reductase to the thylakoid membranes via its CpcD phycobilisome-linker homologous N-terminal domain.

    Relative to ferredoxin:NADP(+) reductase (FNR) from chloroplasts, the comparable enzyme in cyanobacteria contains an additional 9 kDa domain at its amino-terminus. The domain is homologous to the phycocyanin associated linker polypeptide CpcD of the light harvesting phycobilisome antennae. The phenotypic consequences of the genetic removal of this domain from the petH gene, which encodes FNR, have been studied in Synechocystis PCC 6803. The in frame deletion of 75 residues at the amino-terminus, rendered chloroplast length FNR enzyme with normal functionality in linear photosynthetic electron transfer. Salt shock correlated with increased abundance of petH mRNA in the wild-type and mutant alike. The truncation stopped salt stress-inducible increase of Photosystem I-dependent cyclic electron flow. Both photoacoustic determination of the storage of energy from Photosystem I specific far-red light, and the re-reduction kinetics of P700(+), suggest lack of function of the truncated FNR in the plastoquinone-cytochrome b(6)f complex reductase step of the PS I-dependent cyclic electron transfer chain. Independent gold-immunodecoration studies and analysis of FNR distribution through activity staining after native polyacrylamide gelelectrophoresis showed that association of FNR with the thylakoid membranes of Synechocystis PCC 6803 requires the presence of the extended amino-terminal domain of the enzyme. The truncated DeltapetH gene was also transformed into a NAD(P)H dehydrogenase (NDH1) deficient mutant of Synechocystis PCC 6803 (strain M55) (T. Ogawa, Proc. Natl. Acad. Sci. USA 88 (1991) 4275-4279). Phenotypic characterisation of the double mutant supported our conclusion that both the NAD(P)H dehydrogenase complex and FNR contribute independently to the quinone cytochrome b(6)f reductase step in PS I-dependent cyclic electron transfer. The distribution, binding properties and function of FNR in the model cyanobacterium Synechocystis PCC 6803 will be discussed.

    Among the many types of pressure transducers available, the most common in terms of industrial and process control application are bonded strain gage, generally used for gage pressure readings; and variable reluctance, commonly used for differential pressure measurement. The strain gage technique is well developed, covers a wide range of pressure levels, yields rugged transducers, and provides simple signal conditioning and calibration techniques. A line drawing is shown of a typical strain gage. A change in resistance is proportional to the deformation. A cut-away drawing shows a bonded strain gage diaphragm pressure transducer with conditioning electronics. Tabular data give the characteristics of typical transducers used in oil-field automation. It should be pointed out that the environmental specifications such as temperature, vibration, explosive environment, corrosion problems, mounting, and connection types should be considered with equal importance and thoroughness as electric specifications.

    2012-04-01

    The initial-state jet matching method introduced in our previous studies has been applied to the event generation of single W and Z production processes and diboson (WW, WZ and ZZ) production processes at hadron collisions in the framework of the GR@PPA event generator. The generated events reproduce the transverse momentum spectra of weak bosons continuously in the entire kinematical region. The matrix elements (ME) for hard interactions are still at the tree level. As in previous versions, the decays of weak bosons are included in the matrix elements. Therefore, spin correlations and phase-space effects in the decay of weak bosons are exact at the tree level. The program package includes custom-made parton shower programs as well as ME-based hard interaction generators in order to achieve self-consistent jet matching. The generated events can be passed to general-purpose event generators to make the simulation proceed down to the hadron level.

  3. SLUDGE BATCH SUPPLEMENTAL SRAT RUNS EFFECTS OF YIELD STRESS AND CYCLE TIME INCREASE

    Energy Technology Data Exchange (ETDEWEB)

    Fernandez, A.

    2010-08-10

    The Defense Waste Processing Facility (DWPF) has transitioned from Sludge Batch 5 (SB5) processing to Sludge Batch 6 (SB6) processing. Phase III-Tank 40 Chemical Process Cell (CPC) flowsheet simulations have been completed to determine the initial processing conditions for the DWPF transition. The impact of higher yield stress (SB-25) and cycle time extension (SB6-26) on the physical and chemical effects of SB6 processing during the SRAT (Sludge Receipt and Adjustment Tank) cycle were evaluated. No significant impacts on the SRAT chemistry were noted during the higher yield stress run. In particular, no impact on mercury stripping was noted, indicating that settling of elemental mercury was not the primary factor in the low mercury recovery noted in the flowsheet testing. The SRAT product from this run retained the higher yield stress of the starting sludge. The run indicated that ultrasonication is an effective tool to increase the yield stress of simulants to targeted values and the chemistry of downstream processing is not impacted. Significant differences were noted in the cycle time extension test compared to the Phase III flowsheet baseline runs. Large decreases in the ammonia and hydrogen generation rates were noted along with reduced mercury stripping efficiency. The latter effect is similar to that of operating under a high acid stoichiometry. It is conceivable that, under the distinctly different conditions of high formic acid concentration (high acid run) or slow formic acid addition (extended run), that mercury could form amalgams with noble metals, possibly rendering both inert. Thus, the removal of free mercury and noble metals could decrease the rate of catalytic formic acid reactions which would decrease generation of ammonium and hydrogen. The potential underlying reasons for the behavior noted during this run would require additional testing.

  19. Piezoelectrically Initiated Pyrotechnic Igniter

    Science.gov (United States)

    Quince, Asia; Dutton, Maureen; Hicks, Robert; Burnham, Karen

    2013-01-01

    This innovation consists of a pyrotechnic initiator and piezoelectric initiation system. The device will be capable of being initiated mechanically; resisting initiation by EMF, RF, and EMI (electromagnetic field, radio frequency, and electromagnetic interference, respectively); and initiating in water environments and space environments. Current devices of this nature are initiated by the mechanical action of a firing pin against a primer. Primers historically are prone to failure. These failures are commonly known as misfires or hang-fires. In many cases, the primer shows the dent where the firing pin struck the primer, but the primer failed to fire. In devices such as "T" handles, which are commonly used to initiate the blowout of canopies, loss of function of the device may result in loss of crew. In devices such as flares or smoke generators, failure can result in failure to spot a downed pilot. The piezoelectrically initiated ignition system consists of a pyrotechnic device that plugs into a mechanical system (activator), which on activation, generates a high-voltage spark. The activator, when released, will strike a stack of electrically linked piezo crystals, generating a high-voltage, low-amperage current that is then conducted to the pyro-initiator. Within the initiator, an electrode releases a spark that passes through a pyrotechnic first-fire mixture, causing it to combust. The combustion of the first-fire initiates a primary pyrotechnic or explosive powder. If used in a "T" handle, the primary would ramp the speed of burn up to the speed of sound, generating a shock wave that would cause a high explosive to go "high order." In a flare or smoke generator, the secondary would produce the heat necessary to ignite the pyrotechnic mixture. The piezo activator subsystem is redundant in that a second stack of crystals would be struck at the same time with the same activation force, doubling the probability of a first strike spark generation. If the first

  1. Choice of initial therapy

    Full Text Available Current international and national treatment guidelines such as EACS, BHIVA, DHHS or IAS update regularly recommendations on the choice of initial combination antiretroviral treatment (cART regimens. Preferred cART regimens include a backbone with two nucleoside (nucleotide reverse transcriptase inhibitors combined either with one non-nucleoside reverse transcriptase inhibitor or one ritonavir boosted protease inhibitor or more recently one integrase inhibitor. Response rates according to viral load measurements increased in recent years, in particular due to better tolerability. The choice of initial therapy is flexible and influenced by several factors such as height of viral load, genotypic resistance testing, CD4 cell count, co-morbidities, interactions, potential adverse events, (potential for pregnancy, convenience, adherence, costs as well as physician's and patient's preferences. Diverse highly potent initial cART regimens exist. Following the many possibilities, the choice of a regimen is based on a mixture of evidence-informed data and individualized concepts, some of the latter only partly supported by strong evidence. For example, different perceptions and personal experiences exist about boosted protease inhibitors compared to non-nucleoside reverse transcriptase inhibitors or integrase inhibitors and vice versa which may influence the initial choice. This lecture will discuss choices of initial cART in view of international guidelines and the evidence for individualization of initial HIV therapy.

    Schoolbag use by children is a global common concern.. Children carry school books and other amenities in their school bags. Global evidence indicates that daily load carried by school children may have negative health implications. Backpack as a school bag model, is the healthiest way of load carriage for school children. Several initiatives have been launched world over to minimize unhealthy consequences resulting from schoolbags. Based on a situation analysis, Sri Lanka implemented a national healthy schoolbag campaign by joint efforts of Ministries of Health and Education. Actions were contemplated on; strategies for bag weight reduction, introduction of an ergonomically modeled schoolbag and bag behaviour change. New strategies were introduced with awareness campaigns to policy makers, bag manufacturers, parents, teachers and children. Four million schoolchildren benefitted. In 2000, the backpack strategy of "Pack it Light, Wear it Right" was started as a public health initiative in the United States by the American Occupational Therapy Association (AOTA). Over the last eleven years, thousands of occupational therapy practitioners and students participated in educational programs and outreach activities. In 2004, modeled after the success AOTA initiative, the Icelandic Occupational Therapy Association launched a national backpack awareness initiative. This article shares examples of practices that could be implemented in any context to the promote health of children.

  12. Iterative initial condition reconstruction

    Science.gov (United States)

    Schmittfull, Marcel; Baldauf, Tobias; Zaldarriaga, Matias

    2017-07-01

    Motivated by recent developments in perturbative calculations of the nonlinear evolution of large-scale structure, we present an iterative algorithm to reconstruct the initial conditions in a given volume starting from the dark matter distribution in real space. In our algorithm, objects are first moved back iteratively along estimated potential gradients, with a progressively reduced smoothing scale, until a nearly uniform catalog is obtained. The linear initial density is then estimated as the divergence of the cumulative displacement, with an optional second-order correction. This algorithm should undo nonlinear effects up to one-loop order, including the higher-order infrared resummation piece. We test the method using dark matter simulations in real space. At redshift z =0 , we find that after eight iterations the reconstructed density is more than 95% correlated with the initial density at k ≤0.35 h Mpc-1 . The reconstruction also reduces the power in the difference between reconstructed and initial fields by more than 2 orders of magnitude at k ≤0.2 h Mpc-1 , and it extends the range of scales where the full broadband shape of the power spectrum matches linear theory by a factor of 2-3. As a specific application, we consider measurements of the baryonic acoustic oscillation (BAO) scale that can be improved by reducing the degradation effects of large-scale flows. In our idealized dark matter simulations, the method improves the BAO signal-to-noise ratio by a factor of 2.7 at z =0 and by a factor of 2.5 at z =0.6 , improving standard BAO reconstruction by 70% at z =0 and 30% at z =0.6 , and matching the optimal BAO signal and signal-to-noise ratio of the linear density in the same volume. For BAO, the iterative nature of the reconstruction is the most important aspect.

    Dimopoulos, Konstantinos; Artymowski, Michał

    2017-09-01

    Within the α-attractors framework we investigate scalar potentials with the same pole as the one featured in the kinetic term. We show that, in field space, this leads to directions without a plateau. Using this, we present a proposal, which manages to overcome the initial conditions problem of inflation with a plateau. An earlier period of proto-inflation, beginning at Planck scale, accounts for the Universe expansion and arranges the required initial conditions for inflation on the plateau to commence. We show that, if proto-inflation is power-law, it does not suffer from a sub-Planckian eternal inflationary stage, which would otherwise be a problem. A simple model realisation is constructed in the context of α-attractors, which can both generate the inflationary plateau and the exponential slopes around it, necessary for the two inflation stages. Our mechanism allows to assume chaotic initial conditions at the Planck scale for proto-inflation, it is generic and it is shown to work without fine-tuning.

  16. Initiation of dialysis.

    Science.gov (United States)

    Hakim, R M; Lazarus, J M

    1995-11-01

    The decision to initiate dialysis in a patient with progressive renal disease often depends on the physician's assessment of the patient's subjective symptoms of uremia. There is an increasing need to identify objective criteria for such a decision. Recent evidence suggests that malnutrition at the initiation of dialysis is a strong predictor of subsequent increased relative risk of death on dialysis. In this context, the role of prescribed protein restriction as well as the influence of the progression of renal disease on spontaneous dietary protein intake is examined. It is proposed that the indices of malnutrition such as progressive weight loss, serum albumin levels below 4.0 g/dL, serum transferrin levels below 200 mg/dL, and spontaneous dietary protein intake (using 24-hr urinary nitrogen measurement) below 0.8 to 0.7 g/kg per day be considered as objective criteria for the initiation of dialysis. Studies that have examined the role of "early" versus "late" dialysis have consistently shown a better outcome in the patients starting dialysis early. Other studies also suggest that early referral to nephrologists results in improved morbidity and mortality as well as hospitalization costs. An adequate vascular access, as well as social and psychological preparation of the patient, is an important early step in the process.

  17. An Idea of 20% test of the Initial Core Reactor Physics

    Many tests have been performed on the OPR1000 and APR1400 before commercial operation. Some of these tests were performed at reactor power levels of 20% and 50%. The CPC (Core Protection Calculator) power distribution test is one of these tests. It is performed to assure the reliability of the Core Protection Calculator System (CPCS). Through this test, SAM1 is calculated using the snapshots2. The test takes about nine hours at a reactor power level of 20% and about thirty hours at a reactor power level of 50%. SAM used at each reactor power level is as follows: 1. Reactor power of 0% {approx} 20%: Designed SAM (DSAM) 2. Reactor power of 20% {approx} 50%: SAM calculated (C-SAM) at a reactor power of 20% 3. Reactor power 50% {approx} End of Cycle : SAM calculated at a reactor power of 50% As mentioned earlier, SAM is calculated and punched into CPC to assure the reliability of CPCS. Therefore, CPC is operated having penalties with D-SAM until3 reaching a reactor power of 20%. That is, the penalty of CPC will be removed when SAM is calculated and punched into the CPC at a reactor power of 20%. But these penalties are considered to be removed after a reactor power of 50% test in order to maintain the conservatism of the CPC. This is done because the final values calculated using C-SAM, in contrast to those calculated using SAM, a reactor power of 50%, are not correct. This paper began from an idea, 'If so, what would happen if we removed the CPC power distribution test at a reactor power of 20%?'

    The initiation of slug flow in a horizontal pipe can be predicted either by considering the stability of a slug or by considering the stability of a stratified flow. Measurements of the shedding rate of slugs are used to define necessary conditions for the existence of a slug. Recent results show that slugs develop from an unstable stratified flow through the evolution of small wavelength waves into large wavelength waves that have the possibility of growing to form a slug. The mechanism appears to be quite different for fluids with viscosities close to water than for fluids with large viscosities (20 centipoise).

    Much progress has been made in attaining high confinement regimes in magnetic confinement devices. These operating modes tend to be transient, however, due to the onset of MHD instabilities, and their stabilization is critical for improved performance at steady state. This report describes the Feedback Stabilization Initiative (FSI), a broad-based, multi-institutional effort to develop and implement methods for raising the achievable plasma betas through active MHD feedback stabilization. A key element in this proposed effort is the Feedback Stabilization Experiment (FSX), a medium-sized, national facility that would be specifically dedicated to demonstrating beta improvement in reactor relevant plasmas by using a variety of MHD feedback stabilization schemes.

    The Combat Wound Initiative (CWI) program is a collaborative, multidisciplinary, and interservice public-private partnership that provides personalized, state-of-the-art, and complex wound care via targeted clinical and translational research. The CWI uses a bench-to-bedside approach to translational research, including the rapid development of a human extracorporeal shock wave therapy (ESWT) study in complex wounds after establishing the potential efficacy, biologic mechanisms, and safety of this treatment modality in a murine model. Additional clinical trials include the prospective use of clinical data, serum and wound biomarkers, and wound gene expression profiles to predict wound healing/failure and additional clinical patient outcomes following combat-related trauma. These clinical research data are analyzed using machine-based learning algorithms to develop predictive treatment models to guide clinical decision-making. Future CWI directions include additional clinical trials and study centers and the refinement and deployment of our genetically driven, personalized medicine initiative to provide patient-specific care across multiple medical disciplines, with an emphasis on combat casualty care.

    The vast majority of high-energy physicists use and produce software every day. Software skills are usually acquired on the go and dedicated training courses are rare. The LHCb Starterkit is a new training format for getting LHCb collaborators started in effectively using software to perform their research. The initiative, combining courses and online tutorials, focuses on teaching basic skills for research computing, as well as LHCb software specifics. Unlike traditional tutorials we focus on starting with basics, performing all the material live, with a high degree of interactivity, giving priority to understanding the tools as opposed to handing out recipes that work “as if by magic”. The LHCb Starterkit was started by young members of the collaboration inspired by the principles of Software Carpentry, and the material is created in a collaborative fashion using the tools we teach. Three successful entry-level workshops, as well as two advanced ones, have taken place since the start of the initiative i...

Using hippocampus and frontal cortex of a segmental progeroid mouse model lacking Cockayne syndrome protein B (CSBm/m) and C57Bl/6 (WT) controls...... and comparing young (2–5 months) to middle-aged mice (13–14 months), we found that complex I-linked state 3 respiration (CI) was reduced at middle age in CSBm/m hippocampus, but not in CSBm/m cortex or WT brain. In hippocampus of both genotypes, mitochondrial size heterogeneity increased with age. Notably...... content was lower, and hypoxia-induced factor 1α mRNA was greater at both ages in CSBm/m compared to WT brain. Our findings show that decreased CI and increased mitochondrial size heterogeneity are highly associated and point to declining mitochondrial quality control as an initial event in brain aging....

This has since evolved into the Ombudsperson Initiative Group (OIG) currently composed of the following members: Barbro Asman, Stockholm University; Pierre Charrue, CERN AB; Anna Cook, CERN IT; Catherine Delamare, CERN and IT Ombudsperson; Paula Eerola, Lund University; Pauline Gagnon, Indiana University; Eugenia Hatziangeli, CERN AB; Doreen Klem, CERN IT; Bertrand Nicquevert, CERN TS and Laura Stewart, CERN AT. On June 12, members of the OIG met with representatives of Human Resources (HR) and the Equal Opportunity Advisory Panel (EOAP) to discuss the proposal drafted by the OIG. The meeting was very positive. Everybody agreed that the current procedures at CERN applicable in the event of conflict required a thorough review, and that a professionnally trai...

  14. Green Power Initiative

    2013-01-28

    National energy policy supports the gathering of more detailed and authoritative data on the introduction of renewable bio-based fuels into new and existing district energy systems via the application of biomass gasification. The University of Iowa developed a biomass-fueled, university-scale steam generation system based on biomass gasification technologies. The system serves as a state-of-the-art research and educational facility in the emerging application of gasification in steam generation. The facility, which includes a smaller down-draft gasifier and a larger multi-stage biomass boiler, was designed to operate primarily on wood-based fuels, but has provisions for testing other biomass fuel sources produced within a 100-mile radius, providing enough flexibility to meet the fluctuating local supply of biomass from industry and Midwest agriculture. The equipment was installed in an existing, staffed facility. The down-draft gasifier unit is operated by College of Engineering staff and students, under the direct technical supervision of qualified Utilities plant staff. The Green Power Initiative also includes a substantial, innovative educational component. In addition to an onsite, graduate-level research program in biomass fuels, the investigators have integrated undergraduate and graduate level teaching – through classroom studies and experiential learning – and applied research into a biomass-based, university-scale, functioning power plant. University of Iowa is unique in that it currently has multiple renewable energy technologies deployed, including significant biomass combustion (oat hulls) at its Main Power Plant and a new reciprocating engine based renewable district energy system. This project complements and supports the national energy policy and State of Iowa initiatives in ethanol and biodiesel. Byproducts of ethanol and biodiesel processes (distiller grains) as well as industry residues (oat hulls, wood chips, construction and demolition

    2012-05-09

    Project Objective: The overarching objective of the Montana Palladium Research Initiative is to perform scientific research on the properties and uses of palladium in the context of the U.S. Department of Energy's Hydrogen, Fuel Cells and Infrastructure Technologies Program. The purpose of the research will be to explore possible palladium as an alternative to platinum in hydrogen-economy applications. To achieve this objective, the Initiatives activities will focus on several cutting-edge research approaches across a range of disciplines, including metallurgy, biomimetics, instrumentation development, and systems analysis. Background: Platinum-group elements (PGEs) play significant roles in processing hydrogen, an element that shows high potential to address this need in the U.S. and the world for inexpensive, reliable, clean energy. Platinum, however, is a very expensive component of current and planned systems, so less-expensive alternatives that have similar physical properties are being sought. To this end, several tasks have been defined under the rubric of the Montana Palladium Research Iniative. This broad swath of activities will allow progress on several fronts. The membrane-related activities of Task 1 employs state-of-the-art and leading-edge technologies to develop new, ceramic-substrate metallic membranes for the production of high-purity hydrogen, and develop techniques for the production of thin, defect-free platinum group element catalytic membranes for energy production and pollution control. The biomimetic work in Task 2 explores the use of substrate-attached hydrogen-producing enzymes and the encapsulation of palladium in virion-based protein coats to determine their utility for distributed hydrogen production. Task 3 work involves developing laser-induced breakdown spectroscopy (LIBS) as a real-time, in situ diagnostic technique to characterize PGEs nanoparticles for process monitoring and control. The systems engineering work in task 4

    The NIDCR-supported Practice-based Research Network initiative presents dentistry with an unprecedented opportunity by providing a pathway for modifying and advancing the profession. It encourages practitioner participation in the transfer of science into practice for the improvement of patient care. PBRNs vary in infrastructure and design, and sustaining themselves in the long term may involve clinical trial validation by regulatory agencies. This paper discusses the PBRN concept in general and uses the New York University College of Dentistry’s Practitioners Engaged in Applied Research and Learning (PEARL) Network as a model to improve patient outcomes. The PEARL Network is structured to ensure generalizability of results, data integrity, and to provide an infrastructure in which scientists can address clinical practitioner research interests. PEARL evaluates new technologies, conducts comparative effectiveness research, participates in multidisciplinary clinical studies, helps evaluate alternative models of healthcare, educates and trains future clinical faculty for academic positions, expands continuing education to include “benchmarking” as a form of continuous feedback to practitioners, adds value to dental schools’ educational programs, and collaborates with the oral health care and pharmaceutical industries and medical PBRNs to advance the dental profession and further the integration of dental research and practice into contemporary healthcare (NCT00867997, NCT01268605).

    2003-02-07

    The laboratory has invested a significant amount of resources towards the development of high-performance scientific simulation software, including numerical libraries, visualization, steering, software frameworks, and physics packages. Unfortunately, because this software was not designed for interoperability and re-use, it is often difficult to share these sophisticated software packages among applications due to differences in implementation language, programming style, or calling interfaces. This LDRD Strategic Initiative investigated and developed software component technology for high-performance parallel scientific computing to address problems of complexity, re-use, and interoperability for laboratory software. Component technology is an extension of scripting and object-oriented software development techniques that specifically focuses on the needs of software interoperability. Component approaches based on CORBA, COM, and Java technologies are widely used in industry; however, they do not support massively parallel applications in science and engineering. Our research focused on the unique requirements of scientific computing on ASCI-class machines, such as fast in-process connections among components, language interoperability for scientific languages, and data distribution support for massively parallel SPMD components.

    2015-12-01

    Full Text Available Preservation of environment is one of the global problems for the mankind. The concept of sustainable development presented at the governmental level in 1987 urged to fix at the interstate level the basic principles of development of humanity in harmony with the nature. The Charter signed in 1991 “Business and sustainable development” proclaimed a new stage of development of world entrepreneurship – business had to become ecologicallyoriented and to form the ecologically-oriented demand. In recent years it is possible to state the huge growth of technologies of effective environmental management, energy saving and energy efficiency. The leading world corporations include reduction of the ecological aspects in priority strategic objectives, as much as possible promoting transition to the use of green technologies. “Green” experience of the Western companies showed that reduction of influence on environment is not only the task of the state, but also the effective instrument to increase competitiveness of the organization. Besides the growth of favorable perception of the company by consumers, it receives considerable decrease in prime cost of the made production or the rendered services due to effective and economical use of natural resources. Russia is among the first countries who accepted the concept of sustainable development at the legislative level, nevertheless, only recently we can note that technologies of rational environmental management, energy saving and energy efficiency became one of priority problems of its development. In the present article the advanced methods of the state and private initiatives in the field of ecological responsibility are considered, and the methods of overcoming the new challenges are offered.

    This report presents an overview of the Breckinridge Project and summarizes the results achieved during the development phase of the project performed under a Cooperative Agreement with the United States Department of Energy. The Breckinridge Project provides for the design, construction and operation of a 50,000 barrel per day coal liquefaction facility in Breckinridge County, Kentucky. The development of the basic technology used in the Breckinridge Project dates back to the late 1950's and the invention by Hydrocarbon Research, Inc., (HRI) of the ebullated-bed reactor and the H-OIL process. The H-COAL process is based on the H-OIL technology. This coal liquefaction process produces clean low-sulfur petroleum substitutes suitable for most types of hydrocarbon-based fuel and chemical uses regardless of the sulfur content of the coal. A large H-COAL Pilot Plant in operation at Catlettsburg, Kentucky, is converting 220 tons of coal per day into 600 barrels of distillate products by catalytic hydrogenation. The estimated capital cost of the commercial facility is $3.17 billion, and the associated out-of-pocket operating cost is $18 per barrel, both in January 1981 dollars. Financial analysis shows the project to be an attractive investment under certain leveraged conditions which are possible through the assistance of the Synthetic Fuels Corporation. Ashland Synthetic Fuels, Inc. is currently working with the Synthetic Fuels Corporation and potential partners to develop financing for the commercial venture. Critical permits are being obtained and an Environmental Impact Statement is being prepared pursuant to initiating site preparation in early 1983. Commercial operations are expected to start up in early 1988.

    Science.gov (United States)

    1993-01-01

    The Earth's magnetic field, through its variability over a spectrum of spatial and temporal scales, contains fundamental information on the solid Earth and geospace environment (the latter comprising the atmosphere, ionosphere, and magnetosphere). Integrated studies of the geomagnetic field have the potential to address a wide range of important processes in the deep mantle and core, asthenosphere, lithosphere, oceans, and the solar-terrestrial environment. These studies have direct applications to important societal problems, including resource assessment and exploration, natural hazard mitigation, safe navigation, and the maintenance and survivability of communications and power systems on the ground and in space. Studies of the Earth's magnetic field are supported by a variety of federal and state agencies as well as by private industry. Both basic and applied research is presently supported by several federal agencies, including the National Science Foundation (NSF), U.S. Geological Survey (USGS), U.S. Department of Energy (DOE), National Oceanic and Atmospheric Administration (NOAA), National Aeronautics and Space Administration (NASA), and U.S. Department of Defense (DOD) (through the Navy, Air Force, and Defense Mapping Agency). Although each agency has a unique, well-defined mission in geomagnetic studies, many areas of interest overlap. For example, NASA, the Navy, and USGS collaborate closely in the development of main field reference models. NASA, NSF, and the Air Force collaborate in space physics. These interagency linkages need to be strengthened. Over the past decade, new opportunities for fundamental advances in geomagnetic research have emerged as a result of three factors: well-posed, first-order scientific questions; increased interrelation of research activities dealing with geomagnetic phenomena; and recent developments in technology. These new opportunities can be exploited through a national geomagnetic initiative to define objectives and

    2014-01-01

    Full Text Available In the description and scientific consideration of the attitude of children and youth towards their education and development, the concept of student initiative has been gaining ground lately, and it is hence the subject of analysis in this paper. The analysis is important because of the discrepancy between the increased efforts of the key educational policy holders to promote the idea about the importance of the development of student initiative and rare acceptance of this idea among theoreticians, researchers and practitioners dealing with the education and development of children and youth. By concretising the features of initiative student behaviour, our aim was, on the one hand, to observe the structural determinants and scientific status of the very concept of an initiative student, and, on the other, to contribute to the understanding of the initiative behaviour in practice. In the first part of the paper we deal with different notions and concretisations of the features of initiative behaviour of children and youth, which includes the consideration of: basic student initiative, academic student initiative, individual student initiative, the capacity for initiative and personal development initiative. In the second part of the paper, we discuss the relations of the concept of student initiative with the similar general concepts (activity/passivity, proactivity, agency and the concepts immediately related to school environment (student involvement, student participation. The results of our analysis indicate that the concept of student initiative has: particular features that differentiate it from similar concepts; the potential to reach the status of a scientific concept, bearing in mind the initial empirical specifications and general empirical verifiability of the yet unverified determinants of the concept. In the concluding part of the paper, we discuss the implications of the conceptual analysis for further research, as well as for

    2009-01-01

    We present a Monte Carlo generator for a variety of Glauber-like models (the wounded-nucleon model, binary collisions model, mixed model, model with hot spots). These models describe the early stages of relativistic heavy-ion collisions, in particular the spatial distribution of the transverse energy deposition which ultimately leads to production of particles from the interaction region. The original geometric distribution of sources in the transverse plane can be superimposed with a statistical distribution simulating the dispersion in the generated transverse energy in each individual collision. The program generates inter alia the fixed-axes (standard) and variable-axes (participant) two-dimensional profiles of the density of sources in the transverse plane and their azimuthal Fourier components. These profiles can be used in further analysis of physical phenomena, such as the jet quenching, event-by-event hydrodynamics, or analysis of the elliptic flow and its fluctuations. Characteristics of the event (multiplicities, eccentricities, Fourier coefficients, etc.) are stored in a ROOT file and can be analyzed off-line. In particular, event-by-event studies can be carried out in a simple way. A number of ROOT scripts is provided for that purpose. Supplied variants of the code can also be used for the proton-nucleus and deuteron-nucleus collisions.

    In this chapter we examine self-initiated expatriate academics. Universities are to an increasing extent looking for talent beyond national boundaries. Accordingly, self-initiated expatriate academics represent a fast growing group of highly educated professionals who gain employment abroad....... Nonetheless, little research has focused on this group. We investigate if personal characteristics such as age, gender, marital status and seniority affect work outcomes such as work adjustment, work performance, work effectiveness, job satisfaction and time to proficiency. This is done by using data which...... were collected from 428 self-initiated expatriate academics from 60 countries employed in 35 universities in five northern European countries. Results confirm that there are differences in terms of work outcomes among the different types of self-initiated expatriate academics, especially regarding...

    This report details the progress of an effort to determine the quantitative aspects of the initiation of PBX 9502 (95% TATB, 5% Kel-F 800) by copper jets. The particular jet used was that produced by the LAW warhead (66-mm diameter, 42/sup 0/ angle cone, copper-lined, conical shaped charge). Fifteen experiments, in various configurations, have been fired to define the essential parameters for quantitatively measuring the jet performance and initiation of bare PBX 9502. 7 refs., 8 figs.

  7. Initiation of lymphocyte DNA synthesis.

    The initiation of DNA replication in T lymphocytes appears to be regulated by two distinct activities: one associated with proliferation which mediates initiation, and another associated with quiescence which blocks initiation. Activated lymphocytes and proliferating lymphoid cell lines produce an activity, termed ADR, which can initiate DNA replication in isolated, quiescent nuclei. ADR is heat-labile, has protease activity or interacts closely with a protease, and is distinct from the DNA polymerases. ADR activity is absent in quiescent lymphocytes and appears in mitogen-stimulated lymphocytes after IL-2 binding. The generation of active ADR appears to be mediated by phosphorylation of a precursor which is present in resting cells. Nuclei from mitogen-unresponsive lymphocytes fail to initiate DNA replication in response to ADR, of potential importance in the age-related decline of immunity. Quiescent lymphocytes lack ADR and synthesize an ADR-inhibitory activity. The ADR inhibitor is a heat-stable protein which suppresses the initiation of DNA synthesis, but is ineffective at suppressing elongation once DNA strand replication has begun. Nuclei from several neoplastic cell lines fail to respond to the ADR inhibitor, which may play a role in the continuous proliferation of these cells. At least one of these neoplastic cell lines produces both ADR and an inhibitory factor. These findings suggest that the regulation of proliferation is dependent on the balance between activating and inhibitory pathways.

    Although the effect of niacin on the glucose levels in subjects with diabetes mellitus has been investigated, niacin's effects on the glucose levels and atherosclerosis in subjects with normal glucose levels have not been well established. We examined the effect of niacin on the glucose levels, coronary stenosis progression using quantitative coronary angiography, and clinical events in 407 subjects who had a baseline glucose level <100 mg/dl and were enrolled in the Familial Atherosclerosis Treatment Study (FATS), HDL-Atherosclerosis Treatment Study (HATS), Armed Forces Regression Study (AFREGS), or Carotid Plaque Composition by MRI during lipid-lowering (CPC) study testing active niacin therapy. Although the fasting glucose levels increased significantly within 3 years in both subjects treated with niacin (from 85.6 ± 9.5 to 95.5 ± 19.7 mg/dl, p <0.001) and without niacin (from 85.2 ± 9.6 to 90 ± 17.9 mg/dl, p = 0.009), those treated with niacin had a significantly larger increase in glucose levels than those not taking niacin (9.88 vs 4.05 mg/dl, p = 0.002). Overall, 29% of subjects developed impaired fasting glucose within 3 years. Incident impaired fasting glucose was significantly more likely to be observed in subjects treated with niacin than in those who were not. However, the frequency of new-onset diabetes mellitus did not differ significantly between the 2 groups (5.6% vs 4.8%, p = 0.5). Niacin-treated subjects compared to untreated subjects had significantly less change in mean coronary stenosis (0.1 ± 0.3% vs 2 ± 12%, p <0.0001) and less major cardiovascular events (8% vs 21%, p = 0.001). In conclusion, the use of niacin for 3 years in subjects with normal baseline glucose levels was associated with an increase in blood glucose levels and the risk of developing impaired fasting glucose, but not diabetes mellitus, and was associated with a significantly reduced incidence of coronary stenosis progression and major cardiovascular events.

    Full Text Available Abstract Background Both raloxifene and bisphosphonates are indicated for the prevention and treatment of postmenopausal osteoporosis, however these medications have different efficacy and safety profiles. It is plausible that physicians would prescribe these agents to optimize the benefit/risk profile for individual patients. The objective of this study was to compare demographic and clinical characteristics of patients initiating raloxifene with those of patients initiating bisphosphonates for the prevention and treatment of osteoporosis. Methods This study was conducted using a retrospective cohort design. Female beneficiaries (45 years and older with at least one claim for raloxifene or a bisphosphonate in 2003 through 2005 and continuous enrollment in the previous 12 months and subsequent 6 months were identified using a collection of large national commercial, Medicare supplemental, and Medicaid administrative claims databases (MarketScan®. Patients were divided into two cohorts, a combined commercial/Medicare cohort and a Medicaid cohort. Within each cohort, characteristics (demographic, clinical, and resource utilization of patients initiating raloxifene were compared to those of patients initiating bisphosphonate therapy. Group comparisons were made using chi-square tests for proportions of categorical measures and Wilcoxon rank-sum tests for continuous variables. Logistic regression was used to simultaneously examine factors independently associated with initiation of raloxifene versus a bisphosphonate. Results Within both the commercial/Medicare and Medicaid cohorts, raloxifene patients were younger, had fewer comorbid conditions, and fewer pre-existing fractures than bisphosphonate patients. Raloxifene patients in both cohorts were less likely to have had a bone mineral density (BMD screening in the previous year than were bisphosphonate patients, and were also more likely to have used estrogen or estrogen/progestin therapy in the

  11. Initiation of HIV Reverse Transcription

    Directory of Open Access Journals (Sweden)

    Roland Marquet

    2010-01-01

    Full Text Available Reverse transcription of retroviral genomes into double stranded DNA is a key event for viral replication. The very first stage of HIV reverse transcription, the initiation step, involves viral and cellular partners that are selectively packaged into the viral particle, leading to an RNA/protein complex with very specific structural and functional features, some of which being, in the case of HIV-1, linked to particular isolates. Recent understanding of the tight spatio-temporal regulation of reverse transcription and its importance for viral infectivity further points toward reverse transcription and potentially its initiation step as an important drug target.

  12. Light-initiated detonation systems

    Cooper, Stafford S.; Malone, Philip G.; Bartholomew, Stephen W.; Necker, William J.

    1986-09-01

    Numerous light sources could be employed in detonation systems, but lasers have the most efficient coupling to optical fibers and can generate energetic light pulses required for detonation. Flash lamp-pumped, solid state lasers are presently the most useful light source for explosive initiation. Laser diodes in current production cannot generate enough energy for practical applications. The most useful optical fiber for blast line application is a step index fiber with a large core-to-cladding ratio. The large core minimizes energy losses due to misalignment core of fibers in connectors. Couplers that involve mechanically crimped connectors and cleaved fibers, rather than the epoxy-cemented connectors with polished fibers, provide superior energy transmission due to the reduced carbonization at the fiber end. Detonators for optical initiation systems are similar in basic construction to those employed in electrical initiation systems. Explosive and pyrotechnic charges can also be similar. Either primary or secondary explosives can be initiated in present laser-based systems. Two laser detonation systems are presently accessible; a multiple-shot laser with a single-shot, single fiber system designed for use with detonators containing primary explosives. Additional research related to development of low-energy, photoreactive detonators, continuity checking techniques and improved connectors and fibers can produce significant improvements in presently fielded systems.

    2014-02-01

    Opinion is divided on what the exact function of the cerebellum is. Experiments are summarized that support the following views: (1) the cerebellum is a combiner of multiple movement factors; (2) it contains anatomically fixed permanent focal representation of individual body parts (muscles and segments) and movement modes (e.g., vestibular driven vs. cognitive driven); (3) it contains flexible changing representations/memory of physical properties of the body parts including muscle strength, segment inertia, joint viscosity, and segmental interaction torques (dynamics); (4) it contains mechanisms for learning and storage of the properties in item no. 3 through trial-and-error practice; (5) it provides for linkage of body parts, motor modes, and motordynamics via the parallel fiber system; (6) it combines and integrates the many factors so as to initiate coordinated movements of the many body parts; (7) it is thus enabled to play the unique role of initiating coordinated movements; and (8) this unique causative role is evidenced by the fact that: (a) electrical stimulation of the cerebellum can initiate compound coordinated movements; (b) in naturally initiated compound movements, cerebellar discharge precedes that in downstream target structures such as motor cerebral cortex; and (c) cerebellar ablation abolishes the natural production of compound movements in the awake alert individuals.

    The Fayette County Better Buildings Initiative represented a comprehensive and collaborative approach to promoting and implementing energy efficiency improvements. The initiative was designed to focus on implementing energy efficiency improvements in residential units, while simultaneously supporting general marketing of the benefits of implementing energy efficiency measures. The ultimate goal of Fayette County’s Better Buildings Initiative was to implement a total of 1,067 residential energy efficiency retrofits with a minimum 15% estimated energy efficiency savings per unit. Program partners included: United States Department of Energy, Allegheny Power, and Private Industry Council of Westmoreland-Fayette, Fayette County Redevelopment Authority, and various local partners. The program was open to any Fayette County residents who own their home and meet the prequalifying conditions. The level of assistance offered depended upon household income and commitment to undergo a BPI – Certified Audit and implement energy efficiency measures, which aimed to result in at least a 15% reduction in energy usage. The initiative was designed to focus on implementing energy efficiency improvements in residential units, while simultaneously supporting general marketing of the benefits of implementing energy efficiency measures. Additionally, the program had components that involved recruitment and training for employment of persons in the energy sector (green jobs), as well as marketing and implementation of a commercial or community facilities component. The residential component of Fayette County’s Better Buildings Initiative involved a comprehensive approach, providing assistance to low- moderate- and market-rate homeowners. The initiative will also coordinate activities with local utility providers to further incentivize energy efficiency improvements among qualifying homeowners. The commercial component of Fayette County’s Better Building Initiative involved grants

  1. Climatic triggers for peatland initiation

    Peatlands are carbon-dense wetlands characterised by waterlogged, organic-rich soils. Modern-day peatlands have formed mainly since the Last Glacial Maximum (LGM), and despite covering only 3 % of the Earth's land surface are thought to store more than a third of all global soil carbon in the form of poorly decomposed plant detritus. Concern exists that this globally important carbon store may be vulnerable to near-future warming and changes in precipitation patterns, although the links between peatland development and climate are contested. The climatic and other environmental conditions that facilitate the initiation of peat are particularly poorly understood. We present the results of a novel, global study into the climate space of peat initiation since the LGM. We compiled a catalogue of radiocarbon dates of peat initiation from 942 sites that span a range of latitudes and biomes. We used the locations and ages of these peatlands to interrogate downscaled climate hindcasts at 500-yr intervals from a coupled atmosphere-ocean-vegetation general circulation model, HadCM3. This powerful combination of modelling and observational data provides a globally-consistent, temporally-extensive estimate of the climate spaces of peat initiation. In particular, it allows us to identify local and regional climatic changes that may have acted as triggers for peat formation. Peatlands in mid- and high-latitudes of both hemispheres, particularly in maritime locations, developed shortly after local increases in the time integral of growing season temperatures, and were seemingly not influenced by rainfall regime. Peat initiation at such sites appears to have been stimulated by temperature-driven increases in plant productivity in cold, postglacial landscapes, and was not water limited. The exception is the large peatland complex of the Western Siberian Lowlands, which was not glaciated during the last glacial period, and which appears to have been prompted instead by a strong

    2017-02-01

    Penrose proposed that the big bang singularity should be constrained by requiring that the Weyl curvature vanishes there. The idea behind this past hypothesis is attractive because it constrains the initial conditions for the universe in geometric terms and is not confined to a specific early universe paradigm. However, the precise statement of Penrose’s hypothesis is tied to classical space-times and furthermore restricts only the gravitational degrees of freedom. These are encapsulated only in the tensor modes of the commonly used cosmological perturbation theory. Drawing inspiration from the underlying idea, we propose a quantum generalization of Penrose’s hypothesis using the Planck regime in place of the big bang, and simultaneously incorporating tensor as well as scalar modes. Initial conditions selected by this generalization constrain the universe to be as homogeneous and isotropic in the Planck regime as permitted by the Heisenberg uncertainty relations.

    Although blasting differs between and within each industry, as a whole, the mines and quarries are making a shift from a purely ammonium nitrate/fuel oil (ANFO) mixture to a blend of emulsion and ANFO on a straight emulsion. Non-electric (shock tube) initiation systems have provided a viable alternative to the electric detonator (blasting cap). Explosives manufacturers are seeing their roles changes to being blasting contractors or consultants rather than just suppliers. The article discusses these trends and gives examples of typical blasting techniques and amounts of blasting agent used at large USA surface coal mines. Electric caps are still used in blasting underground coal. The Ensign Bickford Co. (EBCo) is developing electronic detonators and has been field testing an electronic initiator, the DIGIDET detonator, for the last four years. When commercially available, electronic detonators will be accurate but will come with a hefty price tag. 2 photos.

    A mobile version of the NASA/DARPA Robonaut humanoid recently completed initial autonomy trials working directly with humans in cluttered environments. This compact robot combines the upper body of the Robonaut system with a Segway Robotic Mobility Platform yielding a dexterous, maneuverable humanoid ideal for interacting with human co-workers in a range of environments. This system uses stereovision to locate human teammates and tools and a navigation system that uses laser range and vision data to follow humans while avoiding obstacles. Tactile sensors provide information to grasping algorithms for efficient tool exchanges. The autonomous architecture utilizes these pre-programmed skills to form complex behaviors. The initial behavior demonstrates a robust capability to assist a human by acquiring a tool from a remotely located individual and then following the human in a cluttered environment with the tool for future use.

    Full Text Available We give a new general definition of arity, yielding the companion notions of signature and associated syntax. This setting is modular in the sense requested by Ghani and Uustalu: merging two extensions of syntax corresponds to building an amalgamated sum. These signatures are too general in the sense that we are not able to prove the existence of an associated syntax in this general context. So we have to select arities and signatures for which there exists the desired initial monad. For this, we follow a track opened by Matthes and Uustalu: we introduce a notion of strengthened arity and prove that the corresponding signatures have initial semantics (i.e. associated syntax. Our strengthened arities admit colimits, which allows the treatment of the λ-calculus with explicit substitution.

    We investigate ideal hydrodynamic evolution, with Landau initial conditions, both in a semi-analytical 1+1D approach and in a numerical code incorporating event-by-event variation with many events and transverse density inhomogeneities. The object of the calculation is to test how fast would a Landau initial condition transition to a commonly used boost-invariant expansion. We show that the transition to boost-invariant flow occurs too late for realistic setups, with corrections of O (20 - 30%) expected at freezeout for most scenarios. Moreover, the deviation from boost-invariance is correlated with both transverse flow and elliptic flow, with the more highly transversely flowing regions also showing the most violation of boost invariance. Therefore, if longitudinal flow is not fully developed at the early stages of heavy ion collisions, 2+1 dimensional hydrodynamics is inadequate to extract transport coefficients of the quark-gluon plasma.

    Atmospheric transformation of monoterpenes gives products that may cause environmental consequences. In this work the NO{sub 3} radical-initiated oxidation of the monoterpenes {alpha}-pinene, {beta}-pinene, {Delta}{sup 3}-carene, and limonene has been investigated. All experiments were conducted in EUPHORE, the EUropean PHOto REactor facility in Valencia, Spain. The aerosol and product yields were measured in experiments with a conversion of the terpenes in the interval from 7 to 400 ppb. The lower end of the concentrations used are close to those measured in ambient pine forest air. Products were measured using long path in situ FTIR. Aerosol yields were obtained using a DMA-CPC system. The aerosol mass yields measured at low concentrations were <1, 10, 15, and 17% for {alpha}-pinene, {beta}-pinene, {Delta}{sup 3}-carene, and limonene, respectively. The total molar alkylnitrate yields were calculated to be 19, 61, 66, and 48%, and molar carbonyl compound yields were estimated to be 71, 14, 29, and 69% for {alpha}-pinene, {beta}-pinene, {Delta}{sup 3}-carene, and limonene, respectively. The aerosol yields were strongly dependent on the amounts of terpene reacted, whereas the nitrate and carbonyl yields do not depend on the amount of terpene converted. The principal carbonyl compound from {alpha}pinene oxidation was pinonaldehyde. In the case of limonene, endolim was tentatively identified and appears to be a major product. The reactions with {beta}-pinene and {Delta}{sup 3}-carene yielded 1--2% of nopinone and 2--3% caronaldehyde, respectively. The results show that it is not possible to use generalized descriptions of terpene chemistry, e.g., in mathematical models.

    Full Text Available This paper discusses the importance of starting point in the simplex algorithm. Three different methods for finding a basic feasible solution are compared throughout performed numerical test examples. We show that our two methods on the Netlib test problems have better performances than the classical algorithm for finding initial solution. The comparison of the introduced optimization softwares is based on the number of iterative steps and on the required CPU time. It is pointed out that on average it takes more iterations to determine the starting point than the number of iterations required by the simplex algorithm to find the optimal solution.

    Initial stages of corrosion of mild steel induced by Klebsiela rhinoscleromatis BO2 were studied in various media. The effect of the microorganism was detected 8-10 h after inoculation. The number of viable cells were virtually unchanged within one month in all media, but the corrosive activity of the strain decreased. The corrosive activity of microorganisms can be determined by spectrophotometry even only after incubation for 24 h. At a low level of organic substrate, even strong colonization with microorganisms does not inevitably result in a significant damage to metals.

    2009-01-01

    Full Text Available The Saudi Initiative for Asthma (SINA provides up-to-date guidelines for healthcare workers managing patients with asthma. SINA was developed by a panel of Saudi experts with respectable academic backgrounds and long-standing experience in the field. SINA is founded on the latest available evidence, local literature, and knowledge of the current setting in Saudi Arabia. Emphasis is placed on understanding the epidemiology, pathophysiology, medications, and clinical presentation. SINA elaborates on the development of patient-doctor partnership, self-management, and control of precipitating factors. Approaches to asthma treatment in SINA are based on disease control by the utilization of Asthma Control Test for the initiation and adjustment of asthma treatment. This guideline is established for the treatment of asthma in both children and adults, with special attention to children 5 years and younger. It is expected that the implementation of these guidelines for treating asthma will lead to better asthma control and decrease patient utilization of the health care system.

    1982-06-11

    Construction of the new flash x-ray induction LINAC (FXR) at Lawrence Livermore National Laboratory has been completed. Initial tuning of the machine has produced stable current pulses in excess of 2 kA at the design energy of 20 MeV, with an 80 ns FWHM pulse width, producing single-pulse radiation doses near 500 Roentgen at one meter from the target. The electronic spot size on the bremsstrahlung target is estimated at 3 to 5 mm. In this paper we will discuss the basic FXR design; running-in and tuning of the machine; emittance measurements; beam stability; switch gap synchronization; and measurements of the radiation dose and angular distribution.

    2013-09-27

    Our main project objective was to implement Plug-in Electric Vehicles (PEV) and charging infrastructure into our electric distribution service territory and help reduce barriers in the process. Our research demonstrated the desire for some to be early adopters of electric vehicles and the effects lack of education plays on others. The response of early adopters was tremendous: with the initial launch of our program we had nearly 60 residential customers interested in taking part in our program. However, our program only allowed for 15 residential participants. Our program provided assistance towards purchasing a PEV and installation of Electric Vehicle Supply Equipment (EVSE). The residential participants have all come to love their PEVs and are more than enthusiastic about promoting the many benefits of driving electric.

    1996-04-01

    The common occurrence of failed medical treatment in microbial keratitis led us to investigate this phenomenon. We retrospectively reviewed all ulcers that presented to our department for 24 consecutive months. We classified each ulcer as either a therapeutic success or failure based on a precise definition of the response to initial antibiotic selection. We then analyzed multiple factors including: antibiotic selection, ophthalmic disease, ulcer characteristics, and management, to determine their significance in the success or failure in treating microbial keratitis. Complications were also examined. Important factors in failure were non-fortified antibiotics (P ulcers (P = 0.051) were of borderline significance. Sensitivity results reflect high sensitivity among successfully treated patients when appropriate antibiotics are chosen. This report provides insight into current practice patterns and potential means to improve success in managing microbial keratitis.

    The County of Somerset, New Jersey, through the Somerset County Improvement Authority (SCIA), applied Federal funding through the U.S. Department of Energy to will apply project funds to buy-down the capital costs of equipment associated with the installation of solar photovoltaic (PV) systems at two sites owned by the County. This Renewable Energy Initiative allows the County to take advantage of clean renewable energy, without any adverse debt impacts, and at a price that results in operating budget savings beyond what is presently available in the marketplace. This project addressed the objectives of the Office of Energy Efficiency and Renewable Energy by making the acquisition of renewable energy more affordable for the County, thereby, encouraging other counties and local units to develop similar programs and increase the deployment of solar energy technologies. The two sites that were funded by the DOE grant are part of a much larger, ambitious, and unique renewable energy project, described in the next section.

  4. On the initiation of subduction

    Science.gov (United States)

    Mueller, Steve; Phillips, Roger J.

    1991-01-01

    Estimates of shear resistance associated with lithospheric thrusting and convergence represent lower bounds on the force necessary to promote trench formation. Three environments proposed as preferential sites of incipient subduction are investigated: passive continental margins, transform faults/fracture zones, and extinct ridges. None of these are predicted to convert into subduction zones simply by the accumulation of local gravitational stresses. Subduction cannot initiate through the foundering of dense oceanic lithosphere immediately adjacent to passive continental margins. The attempted subduction of buoyant material at a mature trench can result in large compressional forces in both subducting and overriding plates. This is the only tectonic force sufficient to trigger the nucleation of a new subduction zone. The ubiquitous distribution of transform faults and fracture zones, combined with the common proximity of these features to mature subduction complexes, suggests that they may represent the most likely sites of trench formation if they are even marginally weaker than normal oceanic lithosphere.

  5. Teaching Evaluation: Waiting for Initiatives

    Directory of Open Access Journals (Sweden)

    Alejandro Canales Sánchez

    2008-08-01

    Full Text Available In this text, it is sustained that, despite the fact that the teaching activity is one of the main functions of higher education institutions or even the only one in most of them, it hasn’t been reflected in the leading initiatives that have been set in motion in this area for the last two decades. In particular, it points out that the wide evaluation politics established in the education system during the late eighties, didn’t consider the teaching activity as a concern issue for the mechanisms or rewards in the evaluation system. Even though the implementation of new actions tried to repair the situation, mainly by improving the quality of working time and the qualifications of the personnel performing these activities; teaching, in strict sense, and the design or application of a new evaluation scheme to strengthen it, didn’t get better.

  6. Montana BioDiesel Initiative

    Energy Technology Data Exchange (ETDEWEB)

    Peyton, Brent [Montana State Univ., Bozeman, MT (United States)

    2017-01-29

    This initiative funding helped put Montana State University (MSU) in a position to help lead in the development of biodiesel production strategies. Recent shortages in electrical power and rising gasoline prices have focused much attention on the development of alternative energy sources that will end our dependence on fossil fuels. In addition, as the concern for environmental impact of utilizing fossil fuels increases, effective strategies must be implemented to reduce emissions or the increased regulations imposed on fossil fuel production will cause economic barriers for their use to continue to increase. Biodiesel has been repeatedly promoted as a more environmentally sound and renewable source of fuel and may prove to be a highly viable solution to provide, at the least, a proportion of our energy needs. Currently there are both practical and economic barriers to the implementation of alternative energy however the advent of these technologies is inevitable. Since many of the same strategies for the storage, transport, and utilization of biodiesel are common with that of fossil fuels, the practical barriers for biodiesel are comparatively minimal. Strategies were developed to harness the CO2 as feedstock to support the growth of biodiesel producing algae. The initiative funding led to the successful funding of highly rated projects in competitive national grant programs in the National Science Foundation and the Department of Energy. This funding put MSU in a key position to develop technologies to utilize the CO2 rich emissions produced in fossil fuel utilization and assembled world experts concerning the growth characteristics of photosynthetic microorganisms capable of producing biodiesel.

    A better understanding of the natural history of osteogenesis imperfecta (OI) in adulthood should improve health care for patients with this rare condition. The Osteogenesis Imperfecta Foundation established the Adult Natural History Initiative (ANHI) in 2010 to give voice to the health concerns of the adult OI community and to begin to address existing knowledge gaps for this condition. Using a web-based platform, 959 adults with self-reported OI, representing a wide range of self-reported disease severity, reported symptoms and health conditions, estimated the impact of these concerns on present and future health-related quality of life (QoL) and completed a Patient-Reported Outcomes Measurement Information System (PROMIS®) survey of health issues. Adults with OI report lower general physical health status (p report generally similar mental health status. Musculoskeletal, auditory, pulmonary, endocrine, and gastrointestinal issues are particular future health-related QoL concerns for these adults. Numerous other statistically significant differences exist among adults with OI as well as between adults with OI and the referent PROMIS® population, but the clinical significance of these differences is uncertain. Adults with OI report lower general health status but are otherwise more similar to the general population than might have been expected. While reassuring, further analysis of the extensive OI-ANHI databank should help identify areas of unique clinical concern and for future research. The OI-ANHI survey experience supports an internet-based strategy for successful patient-centered outcomes research in rare disease populations.

    Purpose - Indiana is listed among the top ten coal states in the USA and annually mines about 35 million short tons (million tons) of coal from the vast reserves of the US Midwest Illinois Coal Basin. The implementation and commercialization of clean coal technologies is important to the economy of the state and has a significant role in the state's energy plan for increasing the use of the state's natural resources. Coal is a substantial Indiana energy resource and also has stable and relatively low costs, compared with the increasing costs of other major fuels. This indigenous energy source enables the promotion of energy independence. The purpose of this paper is to outline the significance of clean coal projects for achieving this objective. Design/methodology/approach - The paper outlines the clean coal initiatives being taken in Indiana and the research carried out at the Indiana Center for Coal Technology Research. Findings - Clean coal power generation and coal for transportation fuels (coal-to-liquids - CTL) are two major topics being investigated in Indiana. Coking coal, data compilation of the bituminous coal qualities within the Indiana coal beds, reducing dependence on coal imports, and provision of an emissions free environment are important topics to state legislators. Originality/value - Lessons learnt from these projects will be of value to other states and countries.

  9. Delamination initiated by a defect

    Biel, A.; Toftegaard, H.

    2016-07-01

    Composite materials in wind turbines are mainly joined with adhesives. Adhesive joining is preferable since it distributes the stresses over a larger area. This study shows how a defect can influence the fracture behaviour of adhesively joined composite. Repeated experiments are performed using double cantilever beam specimens loaded with bending moments. The specimens consist of two 8 mm thick GFRP-laminates which are joined by a 3 mm thick epoxy adhesive. A thin foil close to one of the laminates is used to start the crack. For some of the specimens a defect is created by an initial load-unload operation. During this operation, a clamp is used in order to prevent crack propagation in the main direction. For the specimens without defect, the crack propagates in the middle of the adhesive layer. For the specimens with defect, the crack directly deviates into the laminate. After about 25 mm propagation in the laminate, the crack returns to the adhesive. Compared to the adhesive the fracture energy for the laminate is significantly higher.

  10. German innovation initiative for nanotechnology

    Rieke, Volker; Bachmann, Gerd

    2004-10-01

    In many areas of nanotechnology, Germany can count on a good knowledge basis due to its diverse activities in nanosciences. This knowledge basis, when paired with the production and sales structures needed for implementation and the internationally renowned German talent for system integration, should consequently lead to success in the marketplace. And this is exactly the field of application for the innovation initiative "Nanotechnologie erobert Märkte" (nanotechnology conquers markets) and for the new BMBF strategy in support of nanotechnology. Until now, aspects of nanotechnology have been advanced within the confines of their respective technical subject areas. However, the primary aim of incorporating them into an overall national strategy is to build on Germany's well-developed and internationally competitive research in science and technology to tap the potential of Germany's important industrial sectors for the application of nanotechnology through joint research projects (leading-edge innovations) that strategically target the value-added chain. This development is to be supported by government education policy to remedy a threatening shortage of skilled professionals. To realize that goal, forward-looking political policymaking must become oriented to a uniform concept of innovation, one that takes into consideration all facets of new technological advances that can contribute to a new culture of innovation in Germany. And that includes education and research policy as well as a climate that encourages and supports innovation in science, business and society.

    Geophysical research will be most effective in the fight against terrorism if it is done in cooperation with the expectations of local, state and federal policy makers. New tools to prevent, prepare for, and respond to acts of terrorism are coming from all fields, including geoscience. Globally, monitoring the land, oceans, atmosphere, and space for unusual and suspicious activities can help prevent terrorist acts. Closer to home, geoscience research is used to plan emergency transportation routes and identify infrastructure vulnerabilities. As important as it is for Congress and other policy makers to appreciate the promises and limitations of geophysical research, scientists need to be aware of legislative priorities and expectations. What does Congress expect from the geoscience community in the fight against terrorism and how well does reality meet these expectations? What tools do the 44 different federal agencies with stated Homeland Security missions need from geoscientists? I will address these questions with an overview of current legislative antiterrorism initiatives and policies that relate to the geoscience community.

    We present an antenna shower formalism including contributions from initial-state partons and corresponding backwards evolution. We give a set of phase-space maps and antenna functions for massless partons which define a complete shower formalism suitable for computing observables with hadronic initial states. We focus on the initial-state components: initial-initial and initial-final antenna configurations. The formalism includes comprehensive possibilities for uncertainty estimates. We report on some preliminary results obtained with an implementation in the Vincia antenna-shower framework.

    The Medicare program has transitioned to paying healthcare providers based on the quality of care delivered, not on the quantity. In May 2015, SAGES held its first ever Quality Summit. The goal of this meeting was to provide us with the information necessary to put together a strategic plan for our Society over the next 3-5 years, and to participate actively on a national level to help develop valid measures of quality of surgery. The transition to value-based medicine requires that providers are now measured and reimbursed based on the quality of services they provide rather than the quantity of patients in their care. As of 2014, quality measures must cover 3 of the 6 available National Quality domains. Physician quality reporting system measures are created via a vigorous process which is initiated by the proposal of the quality measure and subsequent validation. Commercial, non-profit, and governmental agencies have now been engaged in the measurement of hospital performance through structural measures, process measures, and increasingly with outcomes measures. This more recent focus on outcomes measures have been linked to hospital payments through the Value-Based Purchasing program. Outcomes measures of quality drive CMS' new program, MACRA, using two formats: Merit-based incentive programs and alternative payment models. But, the quality of information now available is highly variable and difficult for the average consumer to use. Quality metrics serve to guide efforts to improve performance and for consumer education. Professional organizations such as SAGES play a central role in defining the agenda for improving quality, outcomes, and safety. The mission of SAGES is to improve the quality of patient care through education, research, innovation, and leadership, principally in gastrointestinal and endoscopic surgery.

    Benagiano, G; Thomas, B

    2003-09-01

    Over the last twenty years the international community-realizing that the tragedy of women dying during pregnancy and in childbirth could no longer be tolerated-launched a series of initiatives aimed at making safe motherhood a cornerstone of health services in all countries. Making pregnancy and delivery safe events is particularly complex, as it involves infrastructural and logistic, as well as technical, issues. Women die because they have no access to skilled personnel during pregnancy and at the time of delivery and because--if an emergency situation arises--they cannot reach a facility where emergency obstetric services are available. FIGO, the International Federation of Obstetrics and Gynecology-as the only global organization representing the Obstetricians of the world-decided some time ago that it could not limit its activities to proposing technical guidelines and debating scientific issues. It had to move into the field and, through its affiliated societies, help change the ability of the multitude of women in the developing world to obtain skilled attendance at birth. In 1997, plans were made to launch activities in five areas where maternal mortality was particularly high: Central America (Guatemala, Honduras, Nicaragua and El Salvador), Ethiopia, Mozambique, Pakistan, and Uganda. Five member societies from the developed world (the American College of Obstetricians and Gynecologists, the Society of Obstetricians and Gynecologists of Canada, the Italian Society of Obstetrics and Gynecology, the Royal College of Obstetricians and Gynecologists of the United Kingdom; and the Swedish Society of Obstetrics and Gynecology) agreed to provide support to their counterparts in these five selected areas. The project is now in its final stage. Results are, by and large, positive, demonstrating that, by motivating health professionals in the field and for a relatively modest financial outlay, more efficient use of existing services could be made in a sustainable

  16. Shock Initiation of Damaged Explosives

    Energy Technology Data Exchange (ETDEWEB)

    Chidester, S K; Vandersall, K S; Tarver, C M

    2009-10-22

    Explosive and propellant charges are subjected to various mechanical and thermal insults that can increase their sensitivity over the course of their lifetimes. To quantify this effect, shock initiation experiments were performed on mechanically and thermally damaged LX-04 (85% HMX, 15% Viton by weight) and PBX 9502 (95% TATB, 5% Kel-F by weight) to obtain in-situ manganin pressure gauge data and run distances to detonation at various shock pressures. We report the behavior of the HMX-based explosive LX-04 that was damaged mechanically by applying a compressive load of 600 psi for 20,000 cycles, thus creating many small narrow cracks, or by cutting wedge shaped parts that were then loosely reassembled, thus creating a few large cracks. The thermally damaged LX-04 charges were heated to 190 C for long enough for the beta to delta solid - solid phase transition to occur, and then cooled to ambient temperature. Mechanically damaged LX-04 exhibited only slightly increased shock sensitivity, while thermally damaged LX-04 was much more shock sensitive. Similarly, the insensitive explosive PBX 9502 was mechanically damaged using the same two techniques. Since PBX 9502 does not undergo a solid - solid phase transition but does undergo irreversible or 'rachet' growth when thermally cycled, thermal damage to PBX 9502 was induced by this procedure. As for LX-04, the thermally damaged PBX 9502 demonstrated a greater shock sensitivity than mechanically damaged PBX 9502. The Ignition and Growth reactive flow model calculated the increased sensitivities by igniting more damaged LX-04 and PBX 9502 near the shock front based on the measured densities (porosities) of the damaged charges.

    The concept of open data access is a very important topic nowadays. The concept assumes that all data collected or generated by public sector bodies (excepting personal data and data protected under existing privacy protection or accessibility rules) is made publicly accessible in commonly-used, machine-readable formats and can be re-used for any purpose, commercial or non-commercial. Governmental agencies are considered to be the most significant data owners and providers in modern societies. The sheer volume and wealth of this data makes apparent the potential benefits of reusing, combining, and processing governmental data. Even though metadata (information about the data) is sometimes published, administrations typically express reluctance to making their data available, for various reasons, cultural, political, legal, institutional and technical. The governmental spatial information (also called geospatial data, georeferenced data or geodata) producers in Romania are no exception -with the additional situation that even metadata is not usually available. Starting from 2013 a joint program between a Swiss partner (The Swiss Federal Institute of Technology ETH- Zurich - Institute of Cartography and Geoinformation) and a Romanian partner (Technical University of Civil Engineering - UTCB) is developed in order to establish a new approach on the open geodata topic. The main objective of the project GEOIDEA.RO (GEodata Openness Initiative for Development and Economic Advancement in ROmania) is to improve the scientific basis for open geodata model adoption in Romania. Is our believe that publishing government geodata in Romania over the Internet,under an open license and in a reusable format can strengthen citizen engagement and yield new innovative businesses, bringing substantial social and economic gains.

    The Clean Energy Infrastructure Educational Initiative represents a collaborative effort by the University of Dayton, Wright State University and Sinclair Community College. This effort above all aimed to establish energy related programs at each of the universities while also providing outreach to the local, state-wide, and national communities. At the University of Dayton, the grant has aimed at: solidfying a newly created Master's program in Renewable and Clean Energy; helping to establish and staff a regional sustainability organization for SW Ohio. As well, as the prime grantee, the University of Dayton was responsible for insuring curricular sharing between WSU and the University of Dayton. Finally, the grant, through its support of graduate students, and through cooperation with the largest utilities in SW Ohio enabled a region-wide evaluation of over 10,000 commercial building buildings in order to identify the priority buildings in the region for energy reduction. In each, the grant has achieved success. The main focus of Wright State was to continue the development of graduate education in renewable and clean energy. Wright State has done this in a number of ways. First and foremost this was done by continuing the development of the new Renewable and Clean Energy Master's Degree program at Wright State . Development tasks included: continuing development of courses for the Renewable and Clean Energy Master's Degree, increasing the student enrollment, and increasing renewable and clean energy research work. The grant has enabled development and/or improvement of 7 courses. Collectively, the University of Dayton and WSU offer perhaps the most comprehensive list of courses in the renewable and clean energy area in the country. Because of this development, enrollment at WSU has increased from 4 students to 23. Secondly, the grant has helped to support student research aimed in the renewable and clean energy program. The grant helped to solidify

    The radical telomerization of tetrafluoroethylene initiated by benzoyl peroxide (BP) photolysis at λ ≥ 365 nm is studied in acetone, dichloromethane, carbon tetrachloride, and Freon 114B2 at 25°C. The products of synthesis are a mixture of telomers of different molar masses, segregated into soluble and insoluble fractions. To characterize the radicals initiating telomerization, crystalline BP and its solution in ethanol are subjected to low-temperature (77 K) photolysis, with the liquid system serving as a model for BP behavior in solutions of telogens. It is established that radicals are not only initiators but also participate in chain termination reactions, lowering the telomers' molar mass and thus raising the proportion of the soluble fraction. Telomerization initiated by an initiator compound versus initiation by gamma radiation are compared and discussed.

    Seki, K.; Balakrishnan, V.; Nicolis, G.

    1993-01-01

    The time evolution of the mean deviation of initially close trajectories in a stochastic dynamical system is investigated. It is shown both for additive and linearly coupled multiplicative noise that the mean deviation loses its dependence on initial conditions for long times. For shorter times a power law is found for certain types of additive noise processes, in sharp contrast to the exponential separation of initially nearby trajectories in deterministic chaotic systems. Exponential time evolution is obtained for linearly coupled multiplicative noise after an initial transient during which more complex regimes, including a superexponential stage, can take place.

  15. A discussion of numerical subduction initiation

    Science.gov (United States)

    Buiter, Susanne; Ellis, Susan

    2016-04-01

    In nature, subduction can initiate in various ways: Shortening can localise at oceanic transform faults, extinct spreading centres, or inherited passive margin faults; or, alternatively, subduction can be triggered from existing subduction systems by along-strike trench propagation, polarity reversals, or trench jumps. Numerical studies that specifically address subduction initiation have highlighted the roles of sediment loading, rheological strength contrasts, strain softening, and continental topographic gradients, among others. Usually, however, numerical models that aim to investigate subduction dynamics prefer to bypass the subduction initiation phase and its complexities, and focus instead on the stages during which the slab is descending into the mantle. However, even in these models, subduction still needs to begin. It is disturbingly easy to define initial model geometries that do not result in subduction. The specific combination of initial model geometries and values for rheological parameters that successfully initiates subduction has even been referred to as 'the sweet spot' in model space. One cause of subduction initiation failure is when the subducting and overriding plates lock, resulting in either indentation or severe dragging downwards of the overriding plate. This may point to a difficulty in maintaining a weak subduction interface during model evolution. A second factor that may cause difficulties is that initial model geometry and stresses need to balance, as otherwise the first model stages may show spurious deformation associated with reaching equilibrium. A third requirement that may cause problems is that the surface needs to have sufficient displacement freedom to allow the overriding plate to overthrust the subducting plate. That also implies an exclusion of sharp corners in the subduction interface near the surface. It is the interplay of subduction interface geometry, interface strength and subducting plate rheology that determines

    The use of smokeless tobacco (SLT) among women is increasing in India, especially among those with limited education and resources. Preventing the initiation of SLT among women is critical since it has known negative consequences for oral and reproductive health. Most research on tobacco initiation in India focuses on adolescents. This paper addresses the unrecognized issues of post marital initiation among women of reproductive age, highlighting the importance of reproductive stages in women's tobacco initiation. The objective is to examine the correlates of SLT initiation among low income women in Mumbai from pre-marriage through early marriage, first pregnancy and beyond, using case examples to illustrate initiation during each of these stages. In 2011-2012, cross-sectional community level survey data were collected from a representative sample of 409 daily SLT-using married women aged 18-40 years in a low income community in Mumbai. Information on socio-demographics, initiation by reproductive stage, types of tobacco use, childhood exposure to tobacco, learning to use, and initiation influences and reasons were collected through a researcher-administered survey. Univariate and bivariate analysis assessed factors influencing initiation of SLT use by reproductive stage. In addition 42 narratives of tobacco use were collected from a purposive sample of pregnant and non-pregnant married women addressing the same questions in detail. Narratives were transcribed, translated, and coded for key concepts including initiation of tobacco use. Thirty-two percent of women initiated SLT use before marriage, 44% initiated after marriage but before pregnancy, 18.1% initiated during their first pregnancy and the remainder started after their first pregnancy. Mean age of marriage among women in this study was 16 years. Younger women (i.e. age at time of the interview of less than 30 years) were 0.47 [95% CI (0.32, 0.87)] percent less likely to initiate after marriage than women

    2009-01-01

    Direct optical initiation (DOI) of energetic materials using coherent control of localized energy deposition requires depositing energy into the material to produce a critical size hot spot, which allows propagation of the reaction and thereby initiation, The hot spot characteristics needed for growth to initiation can be studied using quantum controlled initiation (QCI). Achieving direct quantum controlled initiation (QCI) in condensed phase systems requires optimally shaped ultrafast laser pulses to coherently guide the energy flow along the desired paths. As a test of our quantum control capabilities we have successfully demonstrated our ability to control the reaction pathway of the chemical system stilbene. An acousto-optical modulator based pulse shaper was used at 266 nm, in a shaped pump/supercontinuum probe technique, to enhance and suppress th relative yields of the cis- to trans-stilbene isomerization. The quantum control techniques tested in the stilbene experiments are currently being used to investigate QCI of the explosive hexanitroazobenzene (HNAB).

    IMPORTANCE There is often considerable uncertainty about the optimal time to initiate maintenance dialysis in individual patients and little medical evidence to guide this decision. OBJECTIVE To gain a better understanding of the factors influencing the timing of initiation of dialysis in clinical practice. DESIGN, SETTING, AND PARTICIPANTS A qualitative analysis was conducted using the electronic medical records from the Department of Veterans Affairs (VA) of a national random sample of 1691 patients for whom the decision to initiate maintenance dialysis occurred in the VA between January 1, 2000, and December 31, 2009. Data analysis took place from June 1 to November 30, 2014. MAIN OUTCOMES AND MEASURES Central themes related to the timing of initiation of dialysis as documented in patients’ electronic medical records. RESULTS Of the 1691 patients, 1264 (74.7%) initiated dialysis as inpatients and 1228 (72.6%) initiated dialysis with a hemodialysis catheter. Cohort members met with a nephrologist during an outpatient clinic visit a median of 3 times (interquartile range, 0–6) in the year prior to initiation of dialysis. The mean (SD) estimated glomerular filtration rate at the time of initiation for cohort members was 10.4 (5.7) mL/min/1.73m2. The timing of initiation of dialysis reflected the complex interplay of at least 3 interrelated and dynamic processes. The first was physician practices, which ranged from practices intended to prepare patients for dialysis to those intended to forestall the need for dialysis by managing the signs and symptoms of uremia with medical interventions. The second process was sources of momentum. Initiation of dialysis was often precipitated by clinical events involving acute illness or medical procedures. In these settings, the imperative to treat often seemed to override patient choice. The third process was patient-physician dynamics. Interactions between patients and physicians were sometimes adversarial, and physician

    For upcoming large-scale HE experiments, an initiation system is needed to ensure uniform and simultaneous burn. To that end, we developed an initiation system based on nitromethane. Initial, small-scale tests characterized the response of the nitromethane in the proposed cylindrical initiator geometry, indicating robust detonation under a variety of conditions such as a plane wave lenses & cylinders of PBX 9501 into a flyer plate or direct-drive. Detonation velocity, as measured by piezoelectric pin time-of-arrival measurements along the length and at bottom of vessel, shows an overdriven response. All cases show a detonation velocity faster than the literature value of 7.3 km s-1 for nitromethane, with the fastest velocity occurring for the 8-detonator, 8'' cylinder case with a velocity = 7.7 km s-1. Streak camera imaging characterized the curvature of the shock front as it arrived at the bottom of the vessel via spark gap. A final test of the initiator system looked at the expansion of the initiator vessel walls via PDV, showing velocities up to 3.5 km s-1. Finally, our initiator was placed inside a secondary vessel containing 1000 lbs of nitromethane. High-speed photography & pin data indicate complete symmetrical burn of the secondary nitromethane.

  14. Mechanisms for initiation of cardiac discordant alternans

    Science.gov (United States)

    Echebarria, B.; Karma, A.

    2007-07-01

    Electrical alternans, defined as a beat-to-beat change in the duration of the excited phase of cardiac cells, is among the known precursors of sudden cardiac death. It may appear as concordant (all the tissue presenting the same phase of oscillation) or discordant (with out-of-phase regions distributed among tissue). Spatially discordant alternans can lead to unidirectional block that initiates reentry and ventricular fibrillation. The role played by tissue heterogeneities and heart rate changes in their initiation remains, however, unclear. We study the mechanisms for initiation of spatially discordant alternans by numerical simulations of an ionic model spatially distributed in a one-dimensional cable and in an anatomical model of the rabbit heart. The effects of CV-restitution, ectopic beats, and the role of spatial gradients of electrical restitution properties are investigated. In homogeneous tissue, the origin of discordant alternans may be dynamical, through CV-restitution, or due to a localized change in the pacing period. We also find that a sudden change of stimulation rate can initiate discordant alternans in the presence of a spatial gradient of APD-restitution without necessitating CV-restitution. The mechanism of, and the conditions for, initiation are determined based on an iterated map analysis of beat to beat changes of APD. This analysis leads to the definition of a vulnerable window for initiation of discordant alternans. Moreover, the pattern of spatially discordant alternans is found to change slowly over several beats following initiation, as reflected in ECG recordings.

    To test the specificity of the association between cigarette advertising and adolescent smoking initiation. A longitudinal survey of 2102 adolescents, aged 10 to 17 years at baseline, who never smoked was conducted by using masked images of 6 cigarette advertisements and 8 other commercial products with all brand information digitally removed. The exposure variable was a combination of contact frequency and cued recall of brands for cigarette and other advertisements. Multilevel mixed-effects Poisson regressions were used to assess smoking initiation 9 months after the baseline assessment as a function of cigarette-advertisement exposure, other advertisement exposure, and baseline covariates. Thirteen percent (n = 277) of students initiated smoking during the observation period. Although the incidence of trying smoking was associated with increased exposure to cigarette advertisements (10% in the low, 12% in the medium, and 19% in the high cigarette-advertisement exposure tertile initiated smoking), exposure to other advertisements did not predict smoking initiation. Compared with low exposure to cigarette advertisements, high exposure remained a significant predictor of adolescent smoking initiation after controlling for baseline covariates (adjusted relative risk: 1.46 [95% confidence interval: 1.08-1.97]; P advertisements and underlines the specificity of the relationship between tobacco marketing and teen smoking; exposure to cigarette advertisements, but not other advertisements, is associated with smoking initiation.

  16. A mechanical energy analysis of gait initiation

    The analysis of gait initiation (the transient state between standing and walking) is an important diagnostic tool to study pathologic gait and to evaluate prosthetic devices. While past studies have quantified mechanical energy of the body during steady-state gait, to date no one has computed the mechanical energy of the body during gait initiation. In this study, gait initiation in seven normal male subjects was studied using a mechanical energy analysis to compute total body energy. The data showed three separate states: quiet standing, gait initiation, and steady-state gait. During gait initiation, the trends in the energy data for the individual segments were similar to those seen during steady-state gait (and in Winter DA, Quanbury AO, Reimer GD. Analysis of instantaneous energy of normal gait. J Biochem 1976;9:253-257), but diminished in amplitude. However, these amplitudes increased to those seen in steady-state during the gait initiation event (GIE), with the greatest increase occurring in the second step due to the push-off of the foundation leg. The baseline level of mechanical energy was due to the potential energy of the individual segments, while the cyclic nature of the data was indicative of the kinetic energy of the particular leg in swing phase during that step. The data presented showed differences in energy trends during gait initiation from those of steady state, thereby demonstrating the importance of this event in the study of locomotion.

    AIM To investigate the impact of coronary artery disease in a cohort of patients resuscitated from cardiac arrest with non-diagnostic electrocardiogram. METHODS From March 2004 to February 2016, 203 consecutive patients resuscitated from in or out-of-hospital sudden cardiac arrest and non-diagnostic post-resuscitation electrocardiogram (defined as ST segment elevation or pre-sumably new left bundle branch block) who underwent invasive coronary angiogram during hospitalization were included. For purpose of analysis and comparison, patients were classified in two groups: Initial shockable rhythm (ventricular tachycardia or ventricular fibrillation; n = 148, 72.9%) and initial non-shockable rhythm (n = 55, 27.1%). Baseline characteristics, coronary angiogram findings including Syntax Score and long-term survival rates were compared. RESULTS Sudden cardiac arrest was witnessed in 95.2% of cases, 66.7% were out-of-hospital patients and 72.4% were male. There were no significant differences in baseline characteristics between groups except for higher mean age (68.1 years vs 61 years, P = 0.001) in the non-shockable rhythm group. Overall 5-year mortality of the resuscitated patients was 37.4%. Patients with non-shockable rhythms had higher mortality (60% vs 29.1%, P < 0.001) and a worst neurological status at hospital discharge based on cerebral performance category score (CPC 1-2: 32.7% vs 53.4%, P = 0.02). Although there were no significant differences in global burden of coronary artery disease defined by Syntax Score (mean Syntax Score: 10.2 vs 10.3, P = 0.96) there was a trend towards a higher incidence of acute coronary lesions in patients with shockable rhythm (29.7% vs 16.4%, P = 0.054). There was also a higher need for ad-hoc percutaneous coronary intervention in this group (21.9% vs 9.1%, P = 0.03). CONCLUSION Initial shockable group of patients had a trend towards higher incidence of acute coronary lesions and higher need of ad-hoc percutaneous intervention vs

    Mundim, Bruno C.; Kelly, Bernard J.; Nakano, Hiroyuki; Zlochower, Yosef; Campanelli, Manuela

    2010-01-01

    "Traditional black-hole binary puncture initial data is conformally flat. This unphysical assumption is coupled with a lack of radiation signature from the binary's past life. As a result, waveforms extracted from evolutions of this data display an abrupt jump. In Kelly et al. [Class. Quantum Grav. 27:114005 (2010)], a new binary black-hole initial data with radiation contents derived in the post-Newtonian (PN) calculations was adapted to puncture evolutions in numerical relativity. This data satisfies the constraint equations to the 2.5PN order, and contains a transverse-traceless "wavy" metric contribution, violating the standard assumption of conformal flatness. Although the evolution contained less spurious radiation, there were undesired features; the unphysical horizon mass loss and the large initial orbital eccentricity. Introducing a hybrid approach to the initial data evaluation, we significantly reduce these undesired features."

    To identify mobile computing initiatives within pharmacy education, including how devices are obtained, supported, and utilized within the curriculum. An 18-item questionnaire was developed and delivered to academic affairs deans (or closest equivalent) of 98 colleges and schools of pharmacy. Fifty-four colleges and schools completed the questionnaire for a 55% completion rate. Thirteen of those schools have implemented mobile computing requirements for students. Twenty schools reported they were likely to formally consider implementing a mobile computing initiative within 5 years. Numerous models of mobile computing initiatives exist in terms of device obtainment, technical support, infrastructure, and utilization within the curriculum. Responders identified flexibility in teaching and learning as the most positive aspect of the initiatives and computer-aided distraction as the most negative, Numerous factors should be taken into consideration when deciding if and how a mobile computing requirement should be implemented.

    The highly streamlined mitochondrial genome encodes almost exclusively a handful of transmembrane components of the respiratory chain complex. In order to ensure the correct assembly of the respiratory chain, the products of these genes must be produced in the correct stoichiometry and inserted into the membrane, posing a unique challenge to the mitochondrial translational system. In this review we describe the proteins orchestrating mitochondrial translation initiation: bacterial-like general initiation factors mIF2 and mIF3, as well as mitochondria-specific components - mRNA-specific translational activators and mRNA-nonspecific accessory initiation factors. We consider how the fast rate of evolution in these organelles has not only created a system that is divergent from that of its bacterial ancestors, but has led to a huge diversity in lineage specific mechanistic features of mitochondrial translation initiation among eukaryotes.

  1. Initiation of Meiotic Recombination in Mammals

    Directory of Open Access Journals (Sweden)

    Rajeev Kumar

    2010-12-01

    Full Text Available Meiotic recombination is initiated by the induction of programmed DNA double strand breaks (DSBs. DSB repair promotes homologous interactions and pairing and leads to the formation of crossovers (COs, which are required for the proper reductional segregation at the first meiotic division. In mammals, several hundred DSBs are generated at the beginning of meiotic prophase by the catalytic activity of SPO11. Currently it is not well understood how the frequency and timing of DSB formation and their localization are regulated. Several approaches in humans and mice have provided an extensive description of the localization of initiation events based on CO mapping, leading to the identification and characterization of preferred sites (hotspots of initiation. This review presents the current knowledge about the proteins known to be involved in this process, the sites where initiation takes place, and the factors that control hotspot localization.

    This study investigates the potential association between montelukast use and psychiatric adverse events by monitoring changes in antidepressant medication dispensing rates before and after initiating montelukast. The primary study group of montelukast initiators was identified using the Wolters Kluwer's SOURCE Lx® pharmacy claims database (WK). This group included 232,159 patients ≤45 years old who had at least two montelukast prescriptions from 2003 to 2007. Comparison groups comprised of 264,704 fluticasone initiators and 89,635 long-acting β-agonist corticosteroid (LABA/ICS) initiators were also identified. Antidepressant medication dispensing rates in these three groups were determined using WK, and changes in rates before and after the first asthma controller medication prescription date were evaluated using interrupted time-series analysis (ITS). ITS was performed separately for four age categories, with a focus on youth (12-17 years) and young adult (18-24 years). For patients 18-24 years old, antidepressant medication dispensing rates increased significantly after initiating montelukast [1.93% (1.55-2.32%, p montelukast. However, similar increases were observed in the fluticasone and LABA/ICS comparison groups. The results of this study cannot support a specific association between initiation of montelukast treatment and an increase in psychiatric adverse effects.

  20. Initialization strategies and diversity in evolutionary timetabling.

    Science.gov (United States)

    Burke, E K; Newall, J P; Weare, R F

    1998-01-01

    This document seeks to provide a scientific basis by which different initialization algorithms for evolutionary timetabling may be compared. Seeding the initial population may be used to improve initial quality and provide a better starting point for the evolutionary algorithm. This must be tempered against the consideration that if the seeding algorithm produces very similar solutions, then the loss of genetic diversity may well lead to a worse final solution. Diversity, we hope, provides a good indication of how good the final solution will be, although only by running the evolutionary algorithm will the exact result be found. We will investigate the effects of heuristic seeding by taking quality and diversity measures of populations generated by heuristic initialization methods on both random and real-life data, as well as assessing the long-term performance of an evolutionary algorithm (found to work well on the timetabling problem) when using heuristic initialization. This will show how the use of heuristic initialization strategies can substantially improve the performance of evolutionary algorithms for the timetabling problem.

    2013-12-01

    Full Text Available General administrative procedure act contains legal norms that are valid for all identical cases. In addition to the general, there are special administrative procedures, customized to the specific administrative areas. Procedure initiation is regulated. Administrative procedure can be initiated at the request of the proponent and ex officio. When the official determines that the conditions for the conduct of administrative procedure are met, before making a decision, all the facts and circumstances relevant to the resolution of administrative matter have to be identified. When there are no legal requirements for the initiation of procedures, the official shall make a decision to reject the application of the party. The procedure is initiated ex officio when stipulated by law or when protection of public interest requires it. When initiating procedure ex officio, the public authority shall take into consideration the petition or other information that indicate the need to protect the public interest. In such cases the applicant is not a party, and the official is obliged to notify the applicant, if initiation of procedures is not accepted ex officio. Based on the notification, the applicant has a right to complain, including the situation when there is no response within the prescribed period of 30 days. Public authority may, therefore it is not obliged to, initiate administrative procedure by public announcement only in a situation where the parties are unknown, while it is obliged to initiate procedure by public announcement when this method of initiating the procedure is prescribed by law. Initiation of procedure with public announcement occurs in rare cases. Due to the application of efficiency and cost-effectiveness principle, two or more administrative procedures can be merged into one procedure by a conclusion. The condition for this is that the rights or obligations of the parties are based on the same legal basis and on the same or

  2. Protein Synthesis Initiation Factors: Phosphorylation and Regulation

    Energy Technology Data Exchange (ETDEWEB)

    Karen S. Browning

    2009-06-15

    The initiation of the synthesis of proteins is a fundamental process shared by all living organisms. Each organism has both shared and unique mechanisms for regulation of this vital process. Higher plants provide for a major amount of fixation of carbon from the environment and turn this carbon into food and fuel sources for our use. However, we have very little understanding of how plants regulate the synthesis of the proteins necessary for these metabolic processes. The research carried out during the grant period sought to address some of these unknowns in the regulation of protein synthesis initiation. Our first goal was to determine if phosphorylation plays a significant role in plant initiation of protein synthesis. The role of phosphorylation, although well documented in mammalian protein synthesis regulation, is not well studied in plants. We showed that several of the factors necessary for the initiation of protein synthesis were targets of plant casein kinase and showed differential phosphorylation by the plant specific isoforms of this kinase. In addition, we identified and confirmed the phosphorylation sites in five of the plant initiation factors. Further, we showed that phosphorylation of one of these factors, eIF5, affected the ability of the factor to participate in the initiation process. Our second goal was to develop a method to make initiation factor 3 (eIF3) using recombinant methods. To date, we successfully cloned and expressed 13/13 subunits of wheat eIF3 in E. coli using de novo gene construction methods. The final step in this process is to place the subunits into three different plasmid operons for co-expression. Successful completion of expression of eIF3 will be an invaluable tool to the plant translation community.

  3. Patterns of tumor initiation in choroidal melanoma.

    2000-07-15

    This study attempts to document the occurrence of tumors with respect to clock hour location and distance from the macula and to evaluate tumor location in relation to retinal topography and light dose distribution on the retinal sphere. Analysis of patterns of tumor initiation may provide new evidence to clarify the controversy regarding the possible light-related etiology of choroidal melanoma. Incident cases of choroidal and ciliary body melanoma in Massachusetts residents diagnosed between 1984 and 1993 were the basis for analysis. Conventional fundus drawings and photos were used to assess the initiation site of each tumor. The initiation site was defined as the intersect between the largest tumor diameter and the largest perpendicular diameter of the tumor. Initiation sites were recorded using spherical coordinates. The retinal sphere was divided into 61 mutually exclusive sectors defined according to clock hour and anteroposterior distance from the macula. Rates of initiation were computed for each sector, overall, and according to gender and other clinical factors. Results were similar in left and right eyes; therefore, these were combined in analysis. Tumor initiation had a predilection for the macula (P preference was observed (P = 0.63). However, the parafoveal zone showed a strong circular trend (P eyes, respectively. Concentric zone location did not vary by gender (P = 0.93) or laterality (P = 0.78). However, posterior location was associated with light iris color (P = 0.01). Tumor diameters were largest in the peripheral region of the fundus and smallest in the macular and ciliary body zone (P color (P = 0.84), or tumor diameter (P = 0.73). Results suggest that tumor initiation is not uniformly distributed, with rates of occurrence concentrated in the macular area and decreasing monotonically with distance from the macula to the ciliary body. This pattern is consistent with the retinal topography and correlates positively with the dose distribution of

  4. Study on planar blast waves initiated by gaseous detonations. I. Estimation of initiation energy

    Energy Technology Data Exchange (ETDEWEB)

    Ohyagi, S.; Yoshihashi, T.; Harigaya, Y.

    1985-01-01

    An experimental study has been made of the initiation of planar blast waves by gaseous detonations. A gaseous detonation initiated by a DDT process is submitted into a long tube filled with air at various initial pressures. The measurement of the decay process of a produced shock wave indicates that it can be treated as a plane source blast wave, although there exists a secondary shock wave, which may be a detonation wave reflected on an end wall of a driver tube, behind the blast wave front. As a result, the decay of a propagation Mach number and a peak overpressure of the wave front as a function of a distance from the initiation source and the initial pressure of the medium are described by the quasi-similar theory of the idealized plane source blast wave. Comparing the experimental results with the theory leads to the estimation of an initiation energy of the blast wave. The initiation energies of oxyhydrogen detonations for three different mixture strengths, three different initial pressures, and two different sizes of the driver tube are estimated to show that about 30-40 percent of the chemical energy contained initially in the driver tube is used to initiate the blast wave. 9 references.

  5. Semiclassical initial value approximation for Green's function.

    Science.gov (United States)

    Kay, Kenneth G

    2010-06-28

    A semiclassical initial value approximation is obtained for the energy-dependent Green's function. For a system with f degrees of freedom the Green's function expression has the form of a (2f-1)-dimensional integral over points on the energy surface and an integral over time along classical trajectories initiated from these points. This approximation is derived by requiring an integral ansatz for Green's function to reduce to Gutzwiller's semiclassical formula when the integrations are performed by the stationary phase method. A simpler approximation is also derived involving only an (f-1)-dimensional integral over momentum variables on a Poincare surface and an integral over time. The relationship between the present expressions and an earlier initial value approximation for energy eigenfunctions is explored. Numerical tests for two-dimensional systems indicate that good accuracy can be obtained from the initial value Green's function for calculations of autocorrelation spectra and time-independent wave functions. The relative advantages of initial value approximations for the energy-dependent Green's function and the time-dependent propagator are discussed.

    To evaluate a clinical leadership initiative in mental health and care of older people settings. Clinical leaders (n=15), clinical nurse managers (n=6), and mentors (n=4) involved in the initiative received three questionnaires assessing perceived change, occupational stress and burnout. A nurse, a support worker and a doctor or therapist with whom the clinical leaders worked, each received the perceived change questionnaire (n=45). A comparative group of senior nurses (n=6) who were not part of the initiative received all three questionnaires. A comparative group of clinical nurse managers (n=3) not involved in the initiative received the perceived change questionnaire. Major improvements in direct care management, communication processes, decision-making, clinical nursing care, reporting and evaluation practices, and support strategies and processes at ward level were indicated. The evaluation also identified evidence of stress, potential burnout and job dissatisfaction. A customised design was negotiated between the evaluators and the NHS trust, and recommendations were made for wider introduction of the initiative, with enhanced planning, an integrated evaluation process and a systematic approach to job redesign.

    Cerebral Performance Category (CPC score I-II. RESULTS: From January to October 2008, a total of 593 patients in nontraumatic CRA were treated and 260 cardiopulmonary resuscitation (CPR attempts were made. There was an initial successful outcome in 52 (20.0% cases, with 16 patients (6.0% alive on the 30th day and 10 being discharged from the hospital (3.9%, of which 6 (2.3% presented CPC I-II score. The CPR at home was inversely associated with 30-day survival (p = 0.001 and hospital discharge survival (p = 0.02. An initial "shockable" rhythm (p = 0.008 was associated with 30-day survival. The response-time and collapse-time intervals until CPR start were significantly shorter in 30-day survivors. At multivariate analysis, independent 30-day mortality predictors were an initial shockable rhythm (odds ratio [OR] = 0.28 and 95% confidence interval [95%CI] = 0.10 - 0.81; p = 0.02 and CPR at home (OR = 3.0 and 95CI% = 1.04 - 8.7; p = 0.04. CONCLUSION: The pre-hospital care of CRA in the city of Porto Alegre has limited results; however, they are comparable to the results from other international locations. It is necessary to reinforce each link of the survival chain to improve pre-hospital care, aiming at improving clinically relevant outcomes.

    Adrenal insufficiency is a rare disease caused by either primary adrenal failure (Addison disease) or by impairment of the hypothalamic-pituitary-adrenal axis. Steroid replacement therapy normalises quality of life, however, adherence can be problematic. This article provides information on adrenal insufficiency focusing on awareness of initial symptoms and on risk scenarios, emergency management and baseline investigations, complete investigations and long term management. Early recognition of adrenal insufficiency is essential to avoid associated morbidity and mortality. Initial diagnosis and decision to treat are based on history and physical examination. Appropriate management includes emergency resuscitation and steroid administration. Initial investigations can include sodium, potassium and blood glucose levels. However, complete investigations can be deferred. Specialist advice should be obtained and long term management includes a Team Care Arrangement. For patients, an emergency plan and emergency identification are essential.

    The MADS-domain transcription factor APETALA1 (AP1) is a key regulator of Arabidopsis flower development. To understand the molecular mechanisms underlying AP1 function, we identified its target genes during floral initiation using a combination of gene expression profiling and genome-wide binding studies. Many of its targets encode transcriptional regulators, including known floral repressors. The latter genes are down-regulated by AP1, suggesting that it initiates floral development by abrogating the inhibitory effects of these genes. Although AP1 acts predominantly as a transcriptional repressor during the earliest stages of flower development, at more advanced stages it also activates regulatory genes required for floral organ formation, indicating a dynamic mode of action. Our results further imply that AP1 orchestrates floral initiation by integrating growth, patterning, and hormonal pathways.

    Impact sensitivity and subsequent impact initiation is one of the key characteristics of explosive materials. Various standardised tests exist, such as the Rotter or BAM impact tests, which allow the relative sensitivity of different materials to be characterised. However, these provide little insight into the underlying behaviour of the material. The use of a periscopic glass-anvil drop-weight apparatus has proven to provide valuable information about the hotspot initiation of many materials. In this paper we describe experiments which apply the technique, in conjunction with high speed video and additional diagnostic instrumentation, to study the mechanism of initiation of modern explosive materials including TATB, LLM-105, Fox-7, HMX, RDX and PETN.

    What were the initial conditions of the star clusters we observe today? Answering this question not only requires accurate observations of their current conditions, but also proper modeling of star cluster evolution over a large amount of time (for a globular cluster typically 12 Gyr). We constrain the initial conditions of observed star clusters in mass and half-mass radius, which provides a starting point for future N-body calculations. To this end we have coupled the fast, parametrized star cluster evolution code EMACSS to the Markov Chain Monte Carlo code emcee within the Astrophysical Multipurpose Software Environment AMUSE, providing a method to determine distributions of probable initial conditions of observed star clusters. In this talk we show how we validated our method and we apply it to observed star clusters in the Galaxy.

    . We find that initial representations have important consequences for the success of the coupled learning process, particularly when communication is constrained and individual rates of learning are high. Under these conditions, initial representations that generate incorrect beliefs can outperform......Coupled learning processes, in which specialists from different domains learn how to make interdependent choices among alternatives, are common in organizations. We explore the role played by initial representations held by the learners in coupled learning processes using a formal agent-based model...... one that does not discriminate among alternatives, or even a mix of correct and incorrect representations among the learners. We draw implications for the design of coupled learning processes in organizations. © 2016 INFORMS....

    Aquarius was launched on June 10, 2011 aboard the Aquarius/SAC-D observatory and the instrument has been operating continuously since the initial turned-on was completed on August 25. The initial observed antenna temperatures were close to predicted and the first salinity map was released in September. In order to map the ocean salinity field, Aquarius includes several special features such as the inclusion of a scatterometer to provide a roughness correction, measurement of the third Stokes parameter to correct for Faraday rotation, and fast sampling to mitigate the effects of RFI. This paper provides an overview of the instrument and an example of initial results. Details are covered in subsequent papers in the session on Aquarius

    The mechanisms involved in the initiation and development of the Greater Everglades peatland ecosystems in South Florida (USA) remain a topic of discussion. In this study, we present an overview of basal ages of peat deposits in South Florida, which shows two major episodes of peatland initiation between 7.0-4.5 kyr and 3.5-2.0 kyr. Our analysis of regional climate proxy datasets led to three alternative hypotheses that may explain the timing and duration of these two peatland initiation episodes: (1) decreased drainage due to relative sea level (RSL) rise during the Holocene (2) gradual increase in precipitation throughout the Holocene, and (3) a combination of increasing precipitation, rising RSL and oscillations in the climate system. We test whether these three hypotheses can explain the pattern of initiation and development of the Greater Everglades peatlands using models that simulate the non-linear processes involved in peat production and decomposition in combination with the local drainage conditions of Southern Florida. The model results suggest that RSL-rise alone cannot predict the onset of peat initiation in the Greater Everglades using our model setup. The model also implies that the climate was wet enough for peat development also during the early Holocene. The first two hypothesized mechanisms in combination with climate oscillations may explain the onset of peat accumulation at 8.2 kyr BP. The two-phased character of peat land initiation may be explained by the spatial distribution of local drainage conditions. As peatland development is highly non-linear, our model uncovers a mechanistic way how peats can suddenly shift from a dry high equilibrium to a wet low equilibrium resulting in lake formation as observed in paleo-ecological studies in the Greater Everglades.

    We look in detail at the process of mapping an astrophysical initial model from a stellar evolution code onto the computational grid of an explicit, Godunov-type code while maintaining hydrostatic equilibrium. This mapping process is common in astrophysical simulations, when it is necessary to follow short-timescale dynamics after a period of long-timescale buildup. We look at the effects of spatial resolution, boundary conditions, the treatment of the gravitational source terms in the hydrodynamics solver, and the initialization process itself. We conclude with a summary detailing the mapping process that yields the lowest ambient velocities in the mapped model.

    1994-01-01

    The behaviour of small corner cracks, inclined or perpendicular to loading direction, is presented. There are two aspects to this investigation: initiation of small cracks and monitoring their subsequent growth. An initial pre-cracking procedure under cyclic compression is adopted to minimize the residual damage at the tip of the growing and self-arresting crack under cyclic compression. A final fatigue specimen, cut from the larger pre-cracked specimen, has two corner flaws. The opening load of corner flaw is monitored using a novel strain gauge approach. The behaviour of small corner cracks is described in terms of growth rate relative to the size of the crack and its shape.

  18. Does turbulence determine the initial mass function?

    Science.gov (United States)

    Liptai, David; Price, Daniel J.; Wurster, James; Bate, Matthew R.

    2017-02-01

    We test the hypothesis that the initial mass function (IMF) is determined by the density probability distribution function (PDF) produced by supersonic turbulence. We compare 14 simulations of star cluster formation in 50 M⊙ molecular cloud cores where the initial turbulence contains either purely solenoidal or purely compressive modes, in each case resolving fragmentation to the opacity limit to determine the resultant IMF. We find statistically indistinguishable IMFs between the two sets of calculations, despite a factor of 2 difference in the star formation rate and in the standard deviation of log (ρ). This suggests that the density PDF, while determining the star formation rate, is not the primary driver of the IMF.

  9. Arc initiation in cathodic arc plasma sources

    Science.gov (United States)

    Anders, Andre

    2002-01-01

    A "triggerless" arc initiation method and apparatus is based on simply switching the arc supply voltage to the electrodes (anode and cathode). Neither a mechanical trigger electrode nor a high voltage flashover from a trigger electrode is required. A conducting path between the anode and cathode is provided, which allows a hot spot to form at a location where the path connects to the cathode. While the conductive path is eroded by the cathode spot action, plasma deposition ensures the ongoing repair of the conducting path. Arc initiation is achieved by simply applying the relatively low voltage of the arc power supply, e.g. 500 V-1 kV, with the insulator between the anode and cathode coated with a conducting layer and the current at the layer-cathode interface concentrated at one or a few contact points. The local power density at these contact points is sufficient for plasma production and thus arc initiation. A conductive surface layer, such as graphite or the material being deposited, is formed on the surface of the insulator which separates the cathode from the anode. The mechanism of plasma production (and arc initiation) is based on explosive destruction of the layer-cathode interface caused by joule heating. The current flow between the thin insulator coating and cathode occurs at only a few contact points so the current density is high.

    Hartly, Tom T.; Lorenzo, Carl F.

    2002-01-01

    Due to the importance of historical effects in fractional-order systems, this paper presents a general fractional-order control theory that includes the time-varying initialization response. Previous studies have not properly accounted for these historical effects. The initialization response, along with the forced response, for fractional-order systems is determined. Stability properties of fractional-order systems are presented in the complex Airplane, which is a transformation of the s-plane. Time responses are discussed with respect to pole positions in the complex Airplane and frequency response behavior is included. A fractional-order vector space representation, which is a generalization of the state space concept, is presented including the initialization response. Control methods for vector representations of initialized fractional-order systems are shown. Nyquist, root-locus, and other input-output control methods are adapted to the control of fractional-order systems. Finally, the fractional-order differintegral is generalized to continuous order-distributions that have the possibility of including a continuum of fractional orders in a system element.

    Clough, Katy; Lim, Eugene A.; DiNunno, Brandon S.; Fischler, Willy; Flauger, Raphael; Paban, Sonia

    2017-09-01

    We consider the effects of inhomogeneous initial conditions in both the scalar field profile and the extrinsic curvature on different inflationary models. In particular, we compare the robustness of small field inflation to that of large field inflation, using numerical simulations with Einstein gravity in 3+1 dimensions. We find that small field inflation can fail in the presence of subdominant gradient energies, suggesting that it is much less robust to inhomogeneities than large field inflation, which withstands dominant gradient energies. However, we also show that small field inflation can be successful even if some regions of spacetime start out in the region of the potential that does not support inflation. In the large field case, we confirm previous results that inflation is robust if the inflaton occupies the inflationary part of the potential. Furthermore, we show that increasing initial scalar gradients will not form sufficiently massive inflation-ending black holes if the initial hypersurface is approximately flat. Finally, we consider the large field case with a varying extrinsic curvature K, such that some regions are initially collapsing. We find that this may again lead to local black holes, but overall the spacetime remains inflationary if the spacetime is open, which confirms previous theoretical studies.

  20. Beam shaping for laser initiated optical primers

    Science.gov (United States)

    Lizotte, Todd E.

    2008-08-01

    Remington was one of the first firearm manufacturing companies to file a patent for laser initiated firearms, in 1969. Nearly 40 years later, the development of laser initiated firearms has not become a mainstream technology in the civilian market. Requiring a battery is definitely a short coming, so it is easy to see how such a concept would be problematic. Having a firearm operate reliably and the delivery of laser energy in an efficient manner to ignite the shock-sensitive explosive primer mixtures is a tall task indeed. There has been considerable research on optical element based methods of transferring or compressing laser energy to ignite primer charges, including windows, laser chip primers and various lens shaped windows to focus the laser energy. The focusing of laser light needs to achieve igniting temperatures upwards of >400°C. Many of the patent filings covering this type of technology discuss simple approaches where a single point of light might be sufficient to perform this task. Alternatively a multi-point method might provide better performance, especially for mission critical applications, such as precision military firearms. This paper covers initial design and performance test of the laser beam shaping optics to create simultaneous multiple point ignition locations and a circumferential intense ring for igniting primer charge compounds. A simple initial test of the ring beam shaping technique was evaluated on a standard large caliber primer to determine its effectiveness on igniting the primer material. Several tests were conducted to gauge the feasibility of laser beam shaping, including optic fabrication and mounting on a cartridge, optic durability and functional ignition performance. Initial data will be presented, including testing of optically elements and empirical primer ignition / burn analysis.

  1. Fast Positive Breakdown, NBEs, and Lightning Initiation

    High power narrrow bipolar events (NBEs) have been found to be produced by arelatively unknown type of discharge, called fast positive breakdown (Rison etal., 2016). The breakdown occurs with a wide range of strengths, both in terms of its broadband sferic and its VHF radiation, and is found to be theinitiating event of many and likely all lightning discharges inside storms. Itdoes not produce a conducting channel but instead appears to be produced by avolumetric system of repeated, cascading positive streamers in virgin air.That positive corona and streamers would be responsible for initiatinglightning was proposed in the 1960s by Loeb, Dawson and Winn. In the 1970sPhelps and Griffiths showed that the streamers would be self-intensifying,leading to negative breakdown being initiated back at their starting points.Petersen et al. (2008) described experimental results showing that thestreamers could be initiated by ice crystals at cold temperatures, and thephysical processes leading to the breakdown being fast has been reported inrecent modeling studies by Shi et al. (2016). In this paper we summarize the observational data in support of the abovefindings, and report on additional observations of NBEs and lightninginitiation currently being obtained at Kennedy Space Center, Florida.

    A novel full-field initialization strategy based on the dimension-reduced projection four-dimensional variational data assimilation (DRP-4DVar) is proposed to alleviate the well-known initial shock occurring in the early years of decadal predictions. It generates consistent initial conditions, which best fit the monthly mean oceanic analysis data along the coupled model trajectory in 1 month windows. Three indices to measure the initial shock intensity are also proposed. Results indicate that this method does reduce the initial shock in decadal predictions by Flexible Global Ocean-Atmosphere-Land System model, Grid-point version 2 (FGOALS-g2) compared with the three-dimensional variational data assimilation-based nudging full-field initialization for the same model and is comparable to or even better than the different initialization strategies for other fifth phase of the Coupled Model Intercomparison Project (CMIP5) models. Better hindcasts of global mean surface air temperature anomalies can be obtained than in other FGOALS-g2 experiments. Due to the good model response to external forcing and the reduction of initial shock, higher decadal prediction skill is achieved than in other CMIP5 models.

  3. Initiation of Gaseous Detonation by Conical Projectiles

    Science.gov (United States)

    Verreault, Jimmy

    Initiation and stabilization of detonation by hypersonic conical projectiles launched into combustible gas mixtures is investigated. This phenomenon must be understood for the design and optimization of specific hypersonic propulsion devices, such as the oblique detonation wave engine and the ram accelerator. The criteria for detonation initiation by a projectile is also related to fundamental aspects of detonation research, such as the requirement for direct initiation of a detonation by a blast wave. Experimental results of this problem also offer useful references for validation of numerical and theoretical modeling. Projectiles with cone half angles varying from 15° to 60° were launched into stoichiometric mixtures of hydrogen/oxygen with 70% argon dilution at initial pressures between 10 and 200 kPa. The projectiles were launched from a combustion-driven gas gun at velocities up to 2.2 km/s (corresponding to 133% of the Chapman Jouguet velocity). Pictures of the flowfields generated by the projectiles were taken via Schlieren photography. Five combustion regimes were observed about the projectile ranging from prompt and delayed oblique detonation wave formation, combustion instabilities, a wave splitting, and an inert shock wave. Two types of transition from the prompt oblique detonation wave regime to the inert shock regime were observed. The first (the delayed oblique detonation wave regime) showed an inert shock attached to the tip of the projectile followed by a sharp kink at the onset of an oblique detonation wave; this regime occurred by decreasing the cone angle at high mixture pressures. The second (the combustion instabilities regime) exhibited large density gradients due to combustion ignition and quenching phenomena; this regime occurred by decreasing the mixture pressure at large cone angles. A number of theoretical models were considered to predict critical conditions for the initiation of oblique detonations. The Lee-Vasiljev model agreed

    2017-12-01

    Trauma care in Spain is not provided in specific centres, which means that health professionals have limited contact to trauma patients. After the setting up of a training program in paediatric trauma, the aim of this study was to evaluate the quality of the initial care provided to these patients before they were admitted to the paediatric intensive care unit (PICU) of a third level hospital (trauma centre), as an indirect measurement of the increase in the number of health professionals trained in trauma. Two cohorts of PICU admissions were reviewed, the first one during the four years immediately before the training courses started (Group 1, period 2001-2004), and the second one during the 4 years (Group 2, period 2012-2015) after nearly 500 professionals were trained. A record was made of the injury mechanism, attending professional, Glasgow coma score (GCS), and paediatric trauma score (PTS). Initial care quality was assessed using five indicators: use of cervical collar, vascular access, orotracheal intubation if GCS ≤ 8, gastric decompression if PTS≤8, and number of actions carried out from the initial four recommended (neck control, provide oxygen, get vascular access, provide IV fluids). Compliance was compared between the 2 periods. A P<.05 was considered statistically significant. A total of 218 patient records were analysed, 105 in Group 1, and 113 in Group 2. The groups showed differences both in injury mechanism and in initial care team. A shift in injury mechanism pattern was observed, with a decrease in car accidents (28% vs 6%; P<.0001). Patients attended to in low complexity hospitals increased from 29.4% to 51.9% (P=.008), and their severity decreased when assessed using the GCS ≤ 8 (29.8% vs 13.5%; P=.004), or PTS≤8 (48.5% vs 29.7%; P=.005). As regards quality indicators, only the use of neck collar improved its compliance (17.3% to 32.7%; P=.01). Patients who received no action in the initial care remained unchanged (19% vs 11%%; P=.15

    Despite the widely documented risks of not breastfeeding, initiation rates remain relatively low in many high-income countries, particularly among women in lower-income groups. In low- and middle-income countries, many women do not follow World Health Organization (WHO) recommendations to initiate breastfeeding within the first hour after birth. This is an update of a Cochrane Review, first published in 2005. To identify and describe health promotion activities intended to increase the initiation rate of breastfeeding.To evaluate the effectiveness of different types of breastfeeding promotion activities, in terms of changing the number of women who initiate breastfeeding.To evaluate the effectiveness of different types of breastfeeding promotion activities, in terms of changing the number of women who initiate breastfeeding early (within one hour after birth). We searched Cochrane Pregnancy and Childbirth's Trials Register (29 February 2016) and scanned reference lists of all articles obtained. Randomised controlled trials (RCTs), with or without blinding, of any breastfeeding promotion intervention in any population group, except women and infants with a specific health problem. Two review authors independently assessed trial reports for inclusion, extracted data and assessed trial quality. Discrepancies were resolved through discussion and a third review author was involved when necessary. We contacted investigators to obtain missing information. Twenty-eight trials involving 107,362 women in seven countries are included in this updated review. Five studies involving 3,124 women did not contribute outcome data and we excluded them from the analyses. The methodological quality of the included trials was mixed, with significant numbers of studies at high or unclear risk of bias due to: inadequate allocation concealment (N = 20); lack of blinding of outcome assessment (N = 20); incomplete outcome data (N = 19); selective reporting (N = 22) and bias from other

    The phycobiliprotein C-phycocyanin (C-PC) is used in cosmetics, diagnostics and foods and also as a nutraceutical or biopharmaceutical. It is produced in the cyanobacterium Arthrospira platensis grown phototrophically in open cultures. C-PC may alternatively be produced heterotrophically in the unicellular rhodophyte Galdieria sulphuraria at higher productivities and under improved hygienic standards if it can be purified as efficiently as C-PC from A. platensis. Ammonium sulfate fractionation, aqueous two-phase extraction, tangential flow ultrafiltration and anion exchange chromatography were evaluated with respect to the purification of C-PC from G. sulphuraria extracts. Galdieria sulphuraria C-PC showed similar properties to those described for cyanobacterial C-PC with respect to separation by all methodologies. The presence of micelles in G. sulphuraria extracts influenced the different procedures. Only chromatography was able to separate C-PC from a second phycobiliprotein, allophycocyanin. C-PC from heterotrophic G. sulphuraria shows similar properties to cyanobacterial C-PC and can be purified to the same standards, despite initial C-PC concentrations being low and impurity concentrations high in G. sulphuraria extracts. © 2013 Society of Chemical Industry.

    2009-11-01

    Global Greenhouse Gas Information System Workshop; Albuquerque, New Mexico, 20-22 May 2009; The second Greenhouse Gas Information System (GHGIS) workshop brought together 74 representatives from 28 organizations including U.S. government agencies, national laboratories, and members of the academic community to address issues related to the understanding, operational monitoring, and tracking of greenhouse gas emissions and carbon offsets. The workshop was held at Sandia National Laboratories and organized by an interagency collaboration among NASA centers, Department of Energy laboratories, and the U.S. National Oceanic and Atmospheric Administration. It was motivated by the perceived need for an integrated interagency, community-wide initiative to provide information about greenhouse gas sources and sinks at policy-relevant temporal and spatial scales. Such an initiative could significantly enhance the ability of national and regional governments, industry, and private citizens to implement and evaluate effective climate change mitigation policies.

    1993-05-01

    The initiation and propagation of deflagration and detonation in mercury fulminate, lead azide, mercuric-5-nitrotetrazole and silver-5-nitrotetrazole have been studied using various techniques. Streak and framing high-speed photography were used to observe these events directly. The main aim has been to investigate the factors which affect deflagration-to-detonation transition (DDT) and the related phenomenon of dead-pressing, which may be regarded as a failure of the DDT process at high pressed densities. These factors include the variable properties of pressed density, void structure, confinement and charge dimension and geometry, and also fixed properties (for a given explosive) such as shock and thermal sensitivities, heat of explosion and the quantity and state of the reaction products. The nature and strength of the initiating stimulus also have a major effect on the subsequent reaction.

    2010-01-01

    Within the Supersonics (SUP) Project of the Fundamental Aeronautics Program (FAP), an initial multidisciplinary design & analysis framework has been developed. A set of low- and intermediate-fidelity discipline design and analysis codes were integrated within a multidisciplinary design and analysis framework and demonstrated on two challenging test cases. The first test case demonstrates an initial capability to design for low boom and performance. The second test case demonstrates rapid assessment of a well-characterized design. The current system has been shown to greatly increase the design and analysis speed and capability, and many future areas for development were identified. This work has established a state-of-the-art capability for immediate use by supersonic concept designers and systems analysts at NASA, while also providing a strong base to build upon for future releases as more multifidelity capabilities are developed and integrated.

    We performed experiments at the Omega Laser Facility to characterize the initial, laser-driven state of a radiative shock experiment. These experiments aimed to measure the shock breakout time from a thin, laser-irradiated Be disk. The data are then used to inform a range of valid model parameters, such as electron flux limiter and polytropic γ, used when simulating radiative shock experiments using radiation hydrodynamics codes. The characterization experiment and the radiative shock experiment use a laser irradiance of ˜7 × 1014 W cm-2 to launch a shock in the Be disk. A velocity interferometer and a streaked optical pyrometer were used to infer the amount of time for the shock to move through the Be disk. The experimental results were compared with simulation results from the Hyades code, which can be used to model the initial conditions of a radiative shock system using the CRASH code.

    This paper presents an account of the initial nuclear space propulsion activities at the Institute for Advanced Studies. At this point two laboratories have been assembled: one for heat pipe construction and testing and another one for thermal cycle analysis. It has also started the design of a thermal loop to study heat extraction and electricity generation in a NEP, the development of a dynamic mathematical model to represent this thermal loop, the selection of gas mixtures as working fluids to the thermal cycle, the production of two heat pipes for properties measurements and to establish design criteria to assemble heat pipes to be used as a heat rejection system. For the reactor core area a review of the core concepts proposed in other countries for space applications was initiated. This review will enable the choice of a core concept suitable to Brazilian needs in space. (author)

    Three tests were conducted to evaluate the effects of firing an isolator in proximity to a barrier or explosive charge. The tests with explosive were conducted without a barrier, on the basis that since any barrier will reduce the shock transmitted to the explosive, bare explosive represents the worst-case from an inadvertent initiation perspective. No reaction was observed. The shock caused by the impact of a representative plastic material on both bare and cased PBX 9501 is calculated in the worst-case, 1-D limit, and the known shock response of the HE is used to estimate minimum run-to-detonation lengths. The estimates demonstrate that even 1-D impacts would not be of concern and that, accordingly, the divergent shocks due to isolator fragment impact are of no concern as initiating stimuli.

    Space exploration has demonstrated that it stimulates the national economy by creating new and improved products, increased employment, and provides a stimulus to education. The exploration of the Moon and Mars under the Space Exploration Initiative has the potential of accelerating this stimulates to the economy. It is difficult to identify all of the concrete ways this will be accomplished. However, many areas can be identified. The space exploration building blocks of power, propulsion, spacecraft, robotics, rovers, mining and manufacturing, communications, navigation, habitats, life support and infrastructures are reviewed to identify possible technology areas. For example, better means for working in hazardous areas and handling hazardous waste are potential outcomes of this initiative. Methods to produce higher quality goods and improve America`s competitiveness in manufacturing will undoubtedly evolve from the need to produce products that must last many years in the harsh environments of space and planetary surfaces. Some ideas for technology transfer are covered in this paper.

Cardiac and vascular symptoms are also commonly present at disease onset. In TA with thoracic or abdominal involvement, although murmur can be present as a physical examination finding, the pulse difference may be absent. Here, we mention a case of TA who initially looked like infective endocarditis and had widespread thoracic murmur.

  11. Topography of photochemical initiation in molecular materials.

    We propose a fluctuation model of the photochemical initiation of an explosive chain reaction in energetic materials. In accordance with the developed model, density fluctuations of photo-excited molecules serve as reaction nucleation sites due to the stochastic character of interactions between photons and energetic molecules. A further development of the reaction is determined by a competition of two processes. The first process is growth in size of the isolated reaction cell, leading to a micro-explosion and release of the material from the cell towards the sample surface. The second process is the overlap of reaction cells due to an increase in their size, leading to the formation of a continuous reaction zone and culminating in a macro-explosion, i.e., explosion of the entire area, covering a large part of the volume of the sample. Within the proposed analytical model, we derived expressions of the explosion probability and the duration of the induction period as a function of the initiation energy (exposure). An experimental verification of the model was performed by exploring the initiation of pentaerythritol tetranitrate (PETN) with the first harmonic of YAG: Nd laser excitation (1,064 nm, 10 ns), which has confirmed the adequacy of the model. This validation allowed us to make a few quantitative assessments and predictions. For example, there must be a few dozen optically excited molecules produced by the initial fluctuations for the explosive decomposition reaction to occur and the life-time of an isolated cell before the micro-explosion must be of the order of microseconds.

    Laser flash photolysis of ONOOH at 355 nm and a pH of 4.0-5.5 causes homolysis of ONOOH nearly exclusively at the N-O bond rather than at the O-O bond (HO(2)(*)/HO(*) > 25:1). All of the NO(*) and HO(2)(*) radicals formed by photolysis subsequently recombine with a rate constant of (1.2 +/- 0.2) x 10(10) M(-1) s(-1) via second-order kinetics, as demonstrated by the return of the UV/vis absorbance to initial levels. Excitation at 266 nm also yields HO(2)(*) and NO(*), but after recombination, the absorbance levels are lower than initial values, possibly because HO(*) produced by the photolysis of water reacts with ONOOH. When NO(3)(-), the product of the ONOOH isomerization, is photolyzed, the ONOO(-) formed is rapidly protonated with a second-order rate constant of (1.7 +/- 0.8) x 10(10) M(-1) s(-1). The ONOOH decays to the starting material, NO(3)(-), with a first-order rate constant of 1.2 s(-1). The quantum yield for the photon-initiated homolysis is 15% for both ONOOH and ONOO(-). We conclude that the ON-OOH and ON-OO(-) bond dissociation energies are similar.

  17. Initiation of diapirism by regional extension

    Initiation of diapirism is one of the least understood aspects of salt tectonics. Sedimentary differential loading is a favorite explanation, but special conditions such as focused sedimentation are needed to trigger diapirism by differential loading. Compilation of published data from 18 of the world's salt-diapir provinces shows that salt upwelling is consistently linked in time with regional extension, whether thin-skinned or thick-skinned. Extended salt basins typically develop salt structures, whereas nonextended basins typically do not. In some basins containing thick salt (SW Iran), diapirism was delayed as long as 400 Ma until the basin was regionally extended. In other salt provinces (Maritime Alps), episodic growth of salt diapirs correlates with episodic regional extension during opening of the Neo-Tethys and Atlantic Oceans. Once initiated, salt diapirism can continue after regional extension is succeeded by contraction or quiescence. Thus even in salt basins overprinted by inversion or orogenic contraction (Morocco, Lusitania, Basque-Cantabrian, North Sea), the diapirs were initiated during extension on divergent continental margins or in intracontinental rifts. This observed temporal link between extension and diapirism is consistent with physical and numerical modeling, which demonstrates that extensional faulting of the overburden directly causes diapirism whether the salt was deposited before, during, or after rifting. Where the overburden is thinned by extension, pressurized salt wells up in response to the shifting positions of fault blocks.

  18. Fighting 'personhood' initiatives in the United States.

    Science.gov (United States)

    Collins, Lee Rubin; Crockin, Susan L

    2012-06-01

    'Personhood' initiatives filed in many states within the United States threaten to impose potentially significant restrictions on infertility treatment, embryo disposition, pre-natal care, abortion, contraception, and stem-cell research, all through attempts to redefine a 'person' or 'human being' as existing from the moment of fertilization or conception, and endowed with the full legal and Constitutional rights of personhood. Virginia's recent, unsuccessful attempt to pass such legislation provides both a dramatic example of these efforts and valuable lessons in the fight against them by infertility advocates and others. Arguments over loss of infertility treatment seemed more persuasive to legislatures than did restrictions on abortion or stem cell research. Indeed, persuading legislators or voters that they could be 'pro-life' and still anti-personhood initiatives was a key strategy, and consumer efforts and media attention were instrumental. The most central lessons, however, may be the degree of intensity and coordinated strategy to shift public perception that lie behind these numerous state efforts, regardless of whether the actual initiatives are won or lost.

  19. Modeling and assessment of electricity market initiatives

    Science.gov (United States)

    Mokrian, Pedram

    This body of work is dedicated to the modeling and assessment of initiatives within electricity markets using the underlying hourly market dynamics. The dissertation presents two separate frameworks that take a bottom-up approach for assessing benefits associated with various demand-side initiatives and other emerging interventions in power markets. Models in support of each framework are presented, and numerical results are used to highlight some impacts based on hourly dynamics. The first framework uses stochastic optimization models to explore the economic feasibility of grid-scale energy storage from the perspective of a price taking, profit maximizing firm facing uncertain market dynamics. This model is then extended to incorporate intermittent wind generation, demonstrating how storage can be used as a potential substitute for transmission capacity. The second framework uses a new dynamic market equilibrium simulation model to address broader economic and environmental impacts of various demand-side initiatives including: energy efficiency, distributed generation, and plug-in hybrid electric vehicles. The general model is calibrated for the California electricity market. The model is used to estimate impacts of the various interventions, taking into account varying market adoption levels and natural gas prices.

    India is the world`s second most populous country, quickly approaching one billion persons. Although it has a well-developed electricity grid, many of the people have little or no access to electricity and all of the benefits associated with it. There are areas that are isolated from the grid and will not be connected for many years, if ever. One such area is the Sundarbans located in the delta region of the two great rivers, the Ganges and Brahmaputra, partially in India and partially in Bangladesh. It is estimated that 1.5 million people live in this area, crisscrossed by many islands and rivers, who have only marginal supplies of electricity generated primarily from diesel generators and batteries. Working with the regional non-governmental organization (NGO), the Ramakrishna Mission, and the West Bengal Renewable Energy Development Agency, the governments of India and the US initiated a rural electrification initiative to demonstrate the economic and technical feasibility of photovoltaics to provide limited supplies of electricity for such applications as solar home lighting systems (SHS), water pumping, vaccine refrigeration, communications, and economic development activities. This paper details initial results from approximately 30 kilowatts of PV systems installed in the area, including socio-economic impacts and technical performance.
