    Full Text Available This paper develops a version of Robust Stochastic Maximum Principle (RSMP applied to the Minimax Mayer Problem formulated for stochastic differential equations with the control-dependent diffusion term. The parametric families of first and second order adjoint stochastic processes are introduced to construct the corresponding Hamiltonian formalism. The Hamiltonian function used for the construction of the robust optimal control is shown to be equal to the Lebesque integral over a parametric set of the standard stochastic Hamiltonians corresponding to a fixed value of the uncertain parameter. The paper deals with a cost function given at finite horizon and containing the mathematical expectation of a terminal term. A terminal condition, covered by a vector function, is also considered. The optimal control strategies, adapted for available information, for the wide class of uncertain systems given by an stochastic differential equation with unknown parameters from a given compact set, are constructed. This problem belongs to the class of minimax stochastic optimization problems. The proof is based on the recent results obtained for Minimax Mayer Problem with a finite uncertainty set [14,43-45] as well as on the variation results of [53] derived for Stochastic Maximum Principle for nonlinear stochastic systems under complete information. The corresponding discussion of the obtain results concludes this study.

  6. Democratic discussion in newspaper reporting of the Australia-United States Free Trade Agreement. (United States)

    Sykes, Robbie


    This article presents a Habermasian analysis of newspaper reporting of the debate surrounding the effect of the Australia-United States Free Trade Agreement (the FTA) on access to medicines through Australian patent law. Habermas's concept of the public sphere is utilised in determining whether discussion within the print media adequately conveyed complex legal issues to the public and facilitated democratic discussion. It was found that newspaper reporting generally failed to meet this standard.

    Lou, Ben-Yong; Yuan, Da-Qiang; Wang, Rui-Hu; Xu, Ying; Wu, Ben-Lai; Han, Lei; Hong, Mao-Chun


    Two supramolecular architectures, [Zn 2( D, L-sala) 2(4-H 2Npy) 2·2H 2O] n ( 1) (4-H 2Npy=4-aminopyridine) and [Zn 2( D, L-sala) 2(4,4'-bpy)·0.5H 2O] n ( 2) (4,4'-bpy=4,4'-bipyridine), have been constructed from dinuclear zinc(II) unit [Zn 2( D, L-sala) 2] (sala= N-(2-hydroxybenzyl)-alanine anion). For 1, four dimmers link together through N-H⋯O hydrogen bonds to give rise to a square ring that is extended into two-dimensional supramolecular network. For 2, dinuclear units are connected by 4,4'-bipyridine to generate a one-dimensional chain with ladder structure, which is connected through hydrogen bonds into three-dimensional supramolecular framework. Complex 1 exhibits intense photoluminescence at 402 nm upon photo-excitation at 348 nm, while complex 2 gives two intense photoluminescent peaks at 464 and 613 nm upon photo-excitation at 350 nm.

    林一; 胡安康; 熊飞; 蒋玮


    The anti-overturning ability and structure safety of jack-up unit in in-place condition are often affected by environment loads, especially wind load. According to the MODU rule, the projected area method is used for calculating the wind load. However, the calculated results are conservative and not good for structure optimization design. In this paper, a 400 ft jack-up is studied as an example. Based on the wind tunnel test and numerical simulation method, some key points of wind load calculation, such as shielding effect, lift effect and shape coefficient of component, are discussed. The study shows that the points mentioned above, which are ignored in the MODU rule calculation, result in the conservative result.

    Full Text Available Objective. The aim is to determine SAPS II and APACHE II scores in medical intensive care unit (MICU patients, to compare them for prediction of patient outcome, and to compare with actual hospital mortality rates for different subgroups of patients. Methods. One hundred and seventy-four patients were included in this analysis over a oneyear period in the MICU, Clinical Center, University of Sarajevo. The following patient data were obtained: demographics, admission diagnosis, SAPS II, APACHE II scores and final outcome. Results. Out of 174 patients, 70 patients (40.2% died. Mean SAPS II and APACHE II scores in all patients were 48.4±17.0 and 21.6±10.3 respectively, and they were significantly different between survivors and non-survivors. SAPS II >50.5 and APACHE II >27.5 can predict the risk of mortality in these patients. There was no statistically significant difference in the clinical values of SAPS II vs APACHE II (p=0.501. A statistically significant positive correlation was established between the values of SAPS II and APACHE II (r=0.708; p=0.001. Patients with an admission diagnosis of sepsis/septic shock had the highest values of both SAPS II and APACHE II scores, and also the highest hospital mortality rate of 55.1%. Conclusion. Both APACHE II and SAPS II had an excellent ability to discriminate between survivors and non-survivors. There was no significant difference in the clinical values of SAPS II and APACHE II. A positive correlation was established between them. Sepsis/septic shock patients had the highest predicted and observed hospital mortality rate.

  13. Performance assessment of the SOFA, APACHE II scoring system, and SAPS II in intensive care unit organophosphate poisoned patients. (United States)

    Kim, Yong Hwan; Yeo, Jung Hoon; Kang, Mun Ju; Lee, Jun Ho; Cho, Kwang Won; Hwang, SeongYoun; Hong, Chong Kun; Lee, Young Hwan; Kim, Yang Weon


    This study assessed the ability of the Sequential Organ Failure Assessment (SOFA) and Acute Physiology, Chronic Health Evaluation (APACHE) II scoring systems, as well as the Simplified Acute Physiology Score (SAPS) II method to predict group mortality in intensive care unit (ICU) patients who were poisoned with organophosphate. The medical records of 149 organophosphate poisoned patients admitted to the ICU from September 2006 to December 2012 were retrospectively examined. The SOFA, APACHE II, and SAPS II were calculated based on initial laboratory data in the Emergency Department, and during the first 24 hr of ICU admission. The probability of death was calculated for each patient based on the SOFA score, APACHE II score, and SAPS II equations. The ability to predict group mortality by the SOFA score, APACHE II score, and SAPS II method was assessed using two by two decision matrices and receiver operating characteristic (ROC) curve analysis. A total of 131 patients (mean age, 61 yr) were enrolled. The sensitivities, specificities, and accuracies were 86.2%, 82.4%, and 83.2% for the SOFA score, respectively; 65.5%, 68.6%, and 67.9% for the APACHE II scoring system, respectively; and 86.2%, 77.5%, and 79.4% for the SAPS II, respectively. The areas under the curve in the ROC curve analysis for the SOFA score, APACHE II scoring system, and SAPS II were 0.896, 0.716, and 0.852, respectively. In conclusion, the SOFA, APACHE II, and SAPS II have different capability to discriminate and estimate early in-hospital mortality of organophosphate poisoned patients. The SOFA score is more useful in predicting mortality, and easier and simpler than the APACHE II and SAPS II.

  19. A summary and discussion of hydrologic data from the Calico Hills nonwelded hydrogeologic unit at Yucca Mountain, Nevada

    Energy Technology Data Exchange (ETDEWEB)

    Loeven, C.


    This report is a summary of available hydrologic data from in situ and laboratory testing of the Calico Hills nonwelded hydrogeologic unit, including hydraulic conductivity, porosity, saturation, pore-size distribution and parameters from curve-fits to pressure-saturation data. Sample statistics of hydraulic conductivity, porosity and saturation data for vitric, devitrified and zeolitic tuffs are presented and discussed. While a high degree of variability is observed in both laboratory and in situ hydraulic conductivity measurements, uncertainties arising from differences in size of laboratory test samples, sample handling, test procedures and insufficient number of samples point to the need for additional data of specific types to adequately characterize the unit. Hydrologic issues related to transport analysis in the Calico Hills nonwelded hydrogeologic unit at Yucca Mountain are discussed together with recommendations for future work. The compiled data are included as an appendix.

  2. Water proton configurations in structures I, II, and H clathrate hydrate unit cells. (United States)

    Takeuchi, Fumihito; Hiratsuka, Masaki; Ohmura, Ryo; Alavi, Saman; Sum, Amadeu K; Yasuoka, Kenji


    Position and orientation of water protons need to be specified when the molecular simulation studies are performed for clathrate hydrates. Positions of oxygen atoms in water are experimentally determined by X-ray diffraction analysis of clathrate hydrate structures, but positions of water hydrogen atoms in the lattice are disordered. This study reports a determination of the water proton coordinates in unit cell of structure I (sI), II (sII), and H (sH) clathrate hydrates that satisfy the ice rules, have the lowest potential energy configuration for the protons, and give a net zero dipole moment. Possible proton coordinates in the unit cell were chosen by analyzing the symmetry of protons on the hexagonal or pentagonal faces in the hydrate cages and generating all possible proton distributions which satisfy the ice rules. We found that in the sI and sII unit cells, proton distributions with small net dipole moments have fairly narrow potential energy spreads of about 1 kJ∕mol. The total Coulomb potential on a test unit charge placed in the cage center for the minimum energy∕minimum dipole unit cell configurations was calculated. In the sI small cages, the Coulomb potential energy spread in each class of cage is less than 0.1 kJ∕mol, while the potential energy spread increases to values up to 6 kJ∕mol in sH and 15 kJ∕mol in the sII cages. The guest environments inside the cages can therefore be substantially different in the sII case. Cartesian coordinates for oxygen and hydrogen atoms in the sI, sII, and sH unit cells are reported for reference.

  3. Advanced Direct Liquefaction Concepts for PETC Generic Units - Phase II

    Energy Technology Data Exchange (ETDEWEB)



    Reported here are the results of Laboratory and Bench- Scale experiments and supporting technical and economic assessments conducted under DOE Contract No. DE- AC22- 91PC91040 during the period April 1, 1997 to June 30, 1997. This contract is with the University of Kentucky Research Foundation which supports work with the University of Kentucky Center for Applied Energy Research, CONSOL, Inc., LDP Associates, and Hydrocarbon Technologies, Inc. This work involves the introduction into the basic two stage liquefaction process several novel concepts which includes dispersed lower- cost catalysts, coal cleaning by oil agglomeration, and distillate hydrotreating and dewaxing. This report includes a data analysis of the ALC- 2 run which was the second continuous run in which Wyodak Black Thunder coal was fed to a two kg/ h bench- scale unit. One of the objectives of that run was to determine the relative activity of several Mo- based coal impregnated catalyst precursors. The precursors included ammonium heptamolybdate (100 mg Mo/ kg dry coal), which was used alone as well as in combination with ferrous sulfate (1% Fe/ dry coal) and nickel sulfate (50 mg Ni/ kg dry coal). The fourth precursor that was tested was phosphomolybdic acid which was used at a level of 100 mg Mo/ kg dry coal. Because of difficulties in effectively separating solids from the product stream, considerable variation in the feed stream occurred. Although the coal feed rate was nearly constant, the amount of recycle solvent varied which resulted in wide variations of resid, unconverted coal and mineral matter in the feed stream. Unfortunately, steady state was not achieved in any of the four conditions that were run. Earlier it was reported that Ni- Mo catalyst appeared to give the best results based upon speculative steady- state yields that were developed.

    Moak, D.J.; Wendling, M.A.


    May 15--21, 1994, the first technical conference was held at Hanford between Ukraine-Chornobyl, Westinghouse Hanford, and SAIC, to exchange technical information and experience gained in cleanup and stabilization of radioactive contamination at Hanford and Chornobyl. Protocol was signed for a second exchange and technology demonstration program in Kiev and near Chornobyl power plants. Technical Exchange No. 2 was held from August 28--September 9, 1994, with 3 focus areas: field demonstration of DOE-Hanford technologies and application to cleanup of contaminated lands resulting from 1986 Chornobyl accident; application of other US DOE-technologies; and observation/evaluation of Ukraine-developed technologies for potential application in USA. Three radiological mapping systems were demonstrated near Chornobyl: man-carried Ultrasonic Ranging and Data System, a mobile radiological data system, and NOMAD field gamma spectroscopy system. The Ukraine-Chornobyl team hosted technical presentations, discussions and field trips for 4.5 days, providing insight on the Chornobyl problem and allowing the US team to present overviews on DOE technologies that may be applicable to the Chornobyl situation. It is concluded that Ukrainian scientists have tremendous talent and expended considerable energy in attempting to tackle such a problem, but economic and cultural conditions with Ukraine have prevented them from acquiring the resources to implement basic aspects of characterization and remediation activities. Most of their publications are in Russian only. Their translation, plus resources to carry out proposals for bench scale and field demonstration projects, could benefit the DOE complex and other nuclear programs. The considerable cultural and economic change occurring in Ukraine, is providing opportunities for private industries to assist in the changes and for DOE, others to apply cleanup technologies, and it is essential that close institutional relations be established.

  5. The performance of customised APACHE II and SAPS II in predicting mortality of mixed critically ill patients in a Thai medical intensive care unit. (United States)

    Khwannimit, B; Bhurayanontachai, R


    The aim of this study was to evaluate and compare the performance of customised Acute Physiology and Chronic Health Evaluation HII (APACHE II) and Simplified Acute Physiology Score HII (SAPS II) in predicting hospital mortality of mixed critically ill Thai patients in a medical intensive care unit. A prospective cohort study was conducted over a four-year period. The subjects were randomly divided into calibration and validation groups. Logistic regression analysis was used for customisation. The performance of the scores was evaluated by the discrimination, calibration and overall fit in the overall group and across subgroups in the validation group. Two thousand and forty consecutive intensive care unit admissions during the study period were split into two groups. Both customised models showed excellent discrimination. The area under the receiver operating characteristic curve of the customised APACHE II was greater than the customised SAPS II (0.925 and 0.892, P APACHE II in overall populations and various subgroups but insufficient calibration for the customised SAPS II. The customised SAPS II showed good calibration in only the younger, postoperative and sepsis patients subgroups. The overall performance of the customised APACHE II was better than the customised SAPS II (Brier score 0.089 and 0.109, respectively). Our results indicate that the customised APACHE II shows better performance than the customised SAPS II in predicting hospital mortality and could be used to predict mortality and quality assessment in our unit or other intensive care units with a similar case mix.

    In the paper the use of binary power plant cycle units for low enthalpy geothermal source exploitation is discussed. Binary power cycles operating in accord with the Organic Rankine Cycle (ORC) concept allow to produce electricity from heat sources like hot water or low pressure steam with high gas content. Geothermal fluids having temperatures as low as 100 degree celsius and less can be utilized with thermodynamic conversion efficiencies and economic cost effectiveness not obtainable with other traditional systems. In these units the conversion of geothermal heat to electricity is obtained by vaporizing a suitable high molecular mass organic fluid and expanding the vapour in a turbine, which remains clean and efficient all through the machine life while the scaling is confined to the easy-to-clean heat exchanger tubes. The chief advantages of this technology are described together with the main fields of application. A 1.3 MW ORC turbogenerator recently installed and tested at Castelnuovo V.C. near Larderello, is described and the performance obtained are discussed as well as the economic effectiveness of both the Castelnuovo machine and a smeller size (all mounted on a 40 feet standard skid) modular unit.

  8. A discussion about public health, lead and Legionella pneumophila in drinking water supplies in the United States. (United States)

    Rosen, Michael B; Pokhrel, Lok R; Weir, Mark H


    Lead (Pb) in public drinking water supplies has garnered much attention since the outset of the Flint water crisis. Pb is a known hazard in multiple environmental matrices, exposure from which results in long-term deleterious health effects in humans. This discussion paper aims to provide a succinct account of environmental Pb exposures with a focus on water Pb levels (WLLs) in the United States. It is understood that there is a strong correlation between WLLs and blood Pb levels (BLLs), and the associated health effects. However, within the Flint water crisis, more than water chemistry and Pb exposure occurred. A cascade of regulatory and bureaucratic failures culminated in the Flint water crisis. This paper will discuss pertinent regulations and responses including their limitations after an overview of the public health effects from Pb exposure as well as discussion on our limitations on monitoring and mitigating Pb in tap water. As the Flint water crisis also included increased Legionnares' disease, caused by Legionella pneumophila, this paper will discuss factors influencing L. pneumophila growth. This will highlight the systemic nature of changes to water chemistry and public health impacts. As we critically analyze these important aspects of water research, we offer discussions to stimulate future water quality research from a new and systemic perspective to inform and guide public health decision-making.

    van Venrooij Janine


    Full Text Available Abstract Background The number of patients in whom mental illness progresses to stages in which acute, and often forced treatment is warranted, is on the increase across Europe. As a consequence, more patients are involuntarily admitted to Psychiatric Intensive Care Units (PICU. From several studies and reports it has become evident that important dissimilarities exist between PICU's. The current study seeks to describe organisational as well as clinical and patient related factors across ten PICU's in and outside the Amsterdam region, adjusted for or stratified by level of urbanization. Method/Design This paper describes the design of the Amsterdam Studies of Acute Psychiatry II (ASAP-II. This study is a prospective observational cohort study comparing PICU's in and outside the Amsterdam region on various patient characteristics, treatment aspects and recovery related variables. Dissimilarities were measured by means of collecting standardized forms which were filled out in the framework of care as usual, by means of questionnaires filled out by mental health care professionals and by means of extracting data from patient files for every consecutive patient admitted at participating PICU's during a specific time period. Urbanization levels for every PICU were calculated conform procedures as proposed by the Dutch Central Bureau for Statistics (CBS. Discussion The current study may provide a deeper understanding of the differences between psychiatric intensive care units that can be used to promote best practice and benchmarking procedures, and thus improve the standard of care.

    Li, Hai-Ying; Li, Shu-Juan; Yang, Nan; Hu, Wen-Li


    To evaluate the feasibility and accuracy of using the Acute Physiology, Age and Chronic Health Evaluation II (APACHE II) scoring system for predicting the risk of nosocomial infection in the neurological intensive care unit (NICU), 216 patients transferred to NICU within 24hours of admission were retrospectively evaluated. Based on admission APACHE II scores, they were classified into three groups, with higher APACHE II scores representing higher infectious risk. The device utilization ratios and device-associated infection ratios of NICU patients were analyzed and compared with published reports on patient outcome. Statistical analysis of nosocomial infection ratios showed obvious differences between the high-risk, middle-risk and low-risk groups (pAPACHE II model in predicting the risk of nosocomial infection was 0.81, which proved to be reliable and consistent with the expectation. In addition, we found statistical differences in the duration of hospital stay (patient-days) and device utilization (device-days) between different risk groups (pAPACHE II scoring system was validated in predicting the risk of nosocomial infection, duration of patient-days and device-days, and providing accurate assessment of patients' condition, so that appropriate prevention strategies can be implemented based on admission APACHE II scores.

  13. Public Reporting of Nursing Home Quality of Care: Lessons from the United States Experience for Canadian Policy Discussion (United States)

    Hutchinson, Alison M.; Draper, Kellie; Sales, Anne E.


    While the demand for continuing care services in Canada grows, the quality of such services has come under increasing scrutiny. Consideration has been given to the use of public reporting of quality data as a mechanism to stimulate quality improvement and promote public accountability for and transparency in service quality. The recent adoption of the Resident Assessment Instrument (RAI) throughout a number of Canadian jurisdictions means that standardized quality data are available for comparisons among facilities across regions, provinces and nationally. In this paper, we explore current knowledge on public reporting in nursing homes in the United States to identify what lessons may inform policy discussion regarding potential use of public reporting in Canada. Based on these findings, we make recommendations regarding how public reporting should be progressed and managed if Canadian jurisdictions were to implement this strategy. PMID:21037828

    A mathematical model was developed to describe the Cu(II) ion inhibition on chemical oxygen demand (COD) removal from synthetic wastewater containing 15 mg l(-1) Cu(II) in an activated sludge unit. Experimental data obtained at different sludge ages (5-30 days) and hydraulic residence times (HRT) (5-25 h) were used to determine the kinetic, stoichiometric and inhibition constants for the COD removal rate in the presence and absence of Cu(II) ions. The inhibition pattern was identified as non-competitive, since Cu(II) ion inhibitions were observed both on maximum specific substrate removal rate (k) and on the saturation constant (Ks) with the inhibition constants of 97 and 18 mg l(-1), respectively, indicating more pronounced inhibition on Ks. The growth yield coefficient (Y) decreased and the death rate constant (b) increased in the presence of Cu(II) ions due to copper ion toxicity on microbial growth with inhibition constants of 29 and 200 mg l(-1), respectively indicating more effective inhibition on the growth yield coefficient or higher maintenance requirements. The mathematical model with the predetermined kinetic constants was able to predict the system performance reasonably well especially at high HRT operations.

  15. Response to Discussion of "Investigation of Oxide Bifilms in Investment Cast Superalloy IN100 Part I and II" (United States)

    Kaplan, M. A.; Fuchs, G. E.


    In his most recent letter (Campbell in Met Trans A, 2017), Professor Campbell provides additional comments on Kaplan and Fuchs papers "Oxides Bifilms in Superalloy: IN100, Parts I and II (Met Trans A 47A:2346-2361, 2016; Met Trans A 47A:2362-2375, 2016) and on their response to his initial comments (Met Trans A 47A:3806-3809, 2016). In this recent submission, Campbell provides some very interesting thoughts on why bifilms were not observed by Kaplan and Fuchs and creates a new theory for the formation of defects referred to as bifilms. However, Campbell again provides no evidence to substantiate the presence of bifilms in Ni-base superalloys or his newly theorized mechanism. The vast majority of Campbell's comments are based solely on the re-interpretation of the photomicrographs and the data reported in the literature, including those presented by Kaplan and Fuchs (Met Trans A 47A:2346-2361, 2016; Met Trans A 47A:2362-2375, 2016). Campbell claims that bifilms are present throughout Ni-base superalloys, even though no one else has reported the presence of bifilms in Ni-base superalloys. In re-interpreting the data and images, Campbell ignores the extensive surface characterization results reported by Kaplan and Fuchs (Met Trans A 47A:2346-2361, 2016; Met Trans A 47A:2362-2375, 2016) that clearly indicate that there are no oxide films or bifilms on the fracture surfaces examined. Please note that this discussion of Campbell's most recent letter will be limited to Ni-base superalloys, since that is the subject of the research reported by Kaplan and Fuchs.

  16. Phase I and II feasibility study report for the 300-FF-5 operable unit

    Energy Technology Data Exchange (ETDEWEB)



    The purpose of this Phase I/II feasibility study is to assemble and screen a list of alternatives for remediation of the 300-FF-5 operable site on the Hanford Reservation. This screening is based on information gathered in the Phase I Remedial Investigation (RI) and on currently available information on remediation technologies. The alternatives remaining after screening provide a range of response actions for remediation. In addition, key data needs are identified for collection during a Phase II RI (if necessary). This Phase I/II FS represents a primary document as defined by the Tri-Party Agreement, but will be followed by a Phase III FS that will further develop the alternatives and provide a detailed evaluation of them. The following remedial action objectives were identified for the 300-FF-5 operable unit: Limit current human exposure to contaminated groundwater in the unit; Limit discharge of contaminated groundwater to the Columbia River; Reduce contaminant concentrations in groundwater below acceptable levels by the year 2018.

  17. Endogenous angiotensin II in the paraventricular nucleus regulates arterial pressure during hypotension in rat, a single-unit study. (United States)

    Khanmoradi, Mehrangiz; Nasimi, Ali


    The hypothalamic paraventricular nucleus (PVN) controls cardiovascular regulation through vasopressin and sympathetic system. The PVN contains angiotensin II (AngII) and AngII receptors. We have already shown that microinjection of AngII into PVN produced a pressor response concomitant with an increase in firing rate of some PVN neurons. This study was performed to find if PVN AngII plays a regulatory function during hypotension. Hypovolemic-hypotension was induced and the possible role of the PVN AngII in returning arterial pressure toward normal was assessed by monitoring cardiovascular response and single-unit activity of the PVN neurons. Hemorrhage augmented the pressor, tachycardic and single-unit responses to AngII. After-hemorrhage injection of PD123319, an AT2 antagonist, into PVN resulted in a significant decrease in firing rate of some neurons, indicating that AngII was released into the PVN due to hemorrhage. Using single-unit recording, we found that PVN receives electrical signals from baroreceptors and from circulating AngII through circumventricular organs. In addition, by producing hemorrhagic-hypotension and bilateral blockade of AT2 receptors of the PVN, we found that AngII regulates arterial pressure toward normal during hypotension. So for the first time, it was verified that brain renin-angiotensin system is also a major regulatory system of the cardiovascular system.

  18. Auxiliary units for refining of high nitrogen content oils: Premium II refinery case

    Energy Technology Data Exchange (ETDEWEB)

    Nicolato, Paolo Contim; Pinotti, Rafael [Petroleo Brasileiro S.A. (PETROBRAS), Rio de Janeiro, RJ (Brazil)


    PETROBRAS is constantly investing on its refining park in order to increase the production of clean and stable fuels and to be capable to process heavier oils with high contaminants content. Sulfur and nitrogen are the main heteroatoms present in petroleum. They are responsible for some undesirable fuels properties like corrosivity and instability, and also emit pollutants when burnt. Hydrotreating and hydrocracking processes are designed to remove these contaminants and adjust other fuel properties, generating, as byproduct, sour gases and sour water streams rich in H{sub 2}S and NH{sub 3}, which are usually sent to Sour Water Treatment Units and Sulfur Recovery Units. The regeneration of the amine used for the light streams treatment, as fuel gas and LPG, also generates sour gas streams that must be also sent to Sulfur Recovery Units. As the ammonia content in the sour streams increases, some design parameters must be adjusted to avoid increasing the Refinery emissions. Sulfur Recovery Units must provide proper NH3 destruction. Sour Water Treatment must have a proper segregation between H{sub 2}S and ammonia streams, whenever desirable. Amine Regeneration Systems must have an efficient procedure to avoid the ammonia concentration in the amine solution. This paper presents some solutions usually applied to the Petroleum Industry and analyses some aspects related to Premium II Refinery Project and how its design will help the Brazilian refining park to meet future environmental regulation and market demands.

    Zhang, Liyan; Rong, Lulu; Hu, Guoli; Jin, Suo; Jia, Wei-Guo; Liu, Ji; Yuan, Guozan


    Six Zn(ii) and Cd(ii) coordination polymers were constructed by treating a 2-substituted 8-hydroxyquinolinate ligand containing a pyridyl group with zinc or cadmium salts, and characterized by a variety of techniques. Interestingly, based on a similar binuclear Zn(ii) or Cd(ii) building unit, the supramolecular structures of the six coordination polymers () exhibit an unprecedented structural diversification due to the different choices of metal salts. and represent a novel 2D framework containing 1D infinite right- and left-handed helical chains. and are 2D coordination frameworks based on binuclear Cd(ii) building units. For and , the L ligands can bridge binuclear building units forming a 1D infinite chain. Interestingly, the adjacent Cd2O2 planes of the 1D chain in are in parallel with each other, while the dihedral angle between the two Zn2O2 planes in is 83.43°. Photoluminescence properties revealed that the six coordination polymers exhibit redshifted emission maximum compared with the free ligand HL, which can be ascribed to an increased conformational rigidity and the fabrication of coplanar binuclear building units M2L2 in . Coordination polymers also display distinct fluorescence lifetimes and quantum yields because of their different metal centers and supramolecular structures.

    Márquez-Godínez, S A; Zonana-Nacach, A; Anzaldo-Campos, M C; Muñoz-Martínez, J A


    To determine the risk of diabetic foot in patients with type II diabetes mellitus (DM) seen in a Family Medicine Unit. The study included type II DM patients with a disease duration ≥ 5 years seen in a Family Medicine Unit, Tijuana, Mexico, during September-December 2011. Neuropathy was assessed with the Diabetic Neuropathy Symptom questionnaire, and pressure sensation using a 10-g Semmes-Weinstein monofilament. A patient had a high risk of diabetic foot if there was sensitivity loss, foot deformities, and non-palpable pedal pulses. We studied 205 patients with an average (± SD) age and DM duration of 59 ± 10 years and 10.7 ± 6.7 years, respectively. Ninety one patients (44%) had a high risk of developing diabetic foot, and it was associated with; an education of less than 6 years (OR 2.3; 95%CI: 1-1-4.1), DM disease duration ≥ 10 years (OR 5.1; 95%CI: 2.8-9.4), female gender (OR 2.0; 95%CI: 1.1-3.6), monthly familiar income diabetic neuropathy, since they have a high risk of diabetic foot.

  5. Meteorologists from the University of Tokyo: Their Exodus to the United States Following World War II. (United States)

    Lewis, John M.


    The emigration of 11 young Japanese meteorologists to the United States following World War II is investigated. Their move is examined with the benefit of a historical backdrop that includes a study of the socioeconomic conditions in Japan and the education that they received at the University of Tokyo. Oral histories and letters of reminiscence from these scientists are used with standard source material to reconstruct the conditions of postwar Japan. The principal results of the study are that 1) these scientists were among the intellectual elite, because of the rigorous screening process in the Japanese educational system; 2) their scientific education was fundamentally grounded in traditional physics and a wide range of geophysical sciences; 3) they all experienced austere living conditions and poor job prospects in the war-torn Japanese economy; and 4) they made a strong scientific connection with U.S. researchers in the areas of numerical experimentation and numerical weather prediction, which facilitated their move to the United States.

  9. [Health and nutritional status of 'alternatively' fed infants and young children, facts and uncertainties. II. Specific nutritional deficiencies; discussion]. (United States)

    Dagnelie, P C; Van Staveren, W A; Hautvast, J G


    This article, which is the second in a series of two articles, discusses available scientific information on the nutritional status of infants and preschool children on alternative diets with regard to calcium, iron, vitamin B12 and D. Some favourable aspects of alternative food habits in such children are also mentioned. Most studies report low intakes of vitamin D and in vegan and macrobiotic children also of calcium and vitamin B12, but it cannot be excluded that some alternative sources of these nutrient may have been missed. Deficiencies have been described for vitamin D and B12 but the evidence is often unconvincing. For example, exposure to sunlight has not been measured in most of the studies on rickets. From the literature available, it would appear that there is a need for longitudinal research on the growth and development of alternatively fed infants and preschool children and for information on the nutrient composition of alternative foods.

  10. Higher-order phylogeny of modern birds (Theropoda, Aves: Neornithes) based on comparative anatomy. II. Analysis and discussion. (United States)

    Livezey, Bradley C; Zusi, Richard L


    . Bootstrapping (based on 10 000 replicates) percentages and ratchet-minimized support (Bremer) indices indicated most nodes to be robust. Several fossil Neornithes (e.g. Dinornithiformes, Aepyornithiformes) were placed within the ingroup a posteriori either through unconstrained, heursitic searches based on the complete matrix augmented by these taxa separately or using backbone-constraints. Analysis confirmed the topology among outgroup Theropoda and achieved robust resolution at virtually all levels of the Neornithes. Findings included monophyly of the palaeognathous birds, comprising the sister taxa Tinamiformes and ratites, respectively, and the Anseriformes and Galliformes as monophyletic sister-groups, together forming the sister-group to other Neornithes exclusive of the Palaeognathae (Neoaves). Noteworthy inferences include: (i) the sister-group to remaining Neoaves comprises a diversity of marine and wading birds; (ii) Podicipedidae are the sister-group of Gaviidae, and not closely related to the Phoenicopteridae, as recently suggested; (iii) the traditional Pelecaniformes, including the shoebill (Balaeniceps rex) as sister-taxon to other members, are monophyletic; (iv) traditional Ciconiiformes are monophyletic; (v) Strigiformes and Falconiformes are sister-groups; (vi) Cathartidae is the sister-group of the remaining Falconiformes; (vii) Ralliformes (Rallidae and Heliornithidae) are the sister-group to the monophyletic Charadriiformes, with the traditionally composed Gruiformes and Turniciformes (Turnicidae and Mesitornithidae) sequentially paraphyletic to the entire foregoing clade; (viii) Opisthocomus hoazin is the sister-taxon to the Cuculiformes (including the Musophagidae); (ix) traditional Caprimulgiformes are monophyletic and the sister-group of the Apodiformes; (x) Trogoniformes are the sister-group of Coliiformes; (xi) Coraciiformes, Piciformes and Passeriformes are mutually monophyletic and closely related; and (xii) the Galbulae are retained within the

  14. Correlation of APACHE II and SOFA scores with length of stay in various surgical intensive care units. (United States)

    Milić, Morena; Goranović, Tatjana; Holjevac, Jadranka Katancić


    The aim of this study was to evaluate the usefulness of using Acute Physiology and Chronic Health Evaluation (APACHE) II score and Sequential Organ Failure Assessment (SOFA) score as the predictors of length of stay (LOS) in various surgical intensive care units (ICUs) and to test the hypothesis that the significance of scoring for predicting LOS is greater in specialized surgical ICUs. We scored patients in a non-specialized general surgical ICU (n = 328) and in a specialized cardiosurgical ICU (n = 158) consecutively on admission (APACHE II-1st day; SOFA-1st day) and on third day of stay (APACHE II-3rd day; SOFA-3rd day) in a 4-month period. LOS and APACHE II/SOFA scores were significantly correlated both on admission and on third day of stay in the general surgical ICU (APACHE II-1st day r = 0.289; SOFA-1st day r = 0.306; APACHE II-3rd day r = 0.728; SOFA-3rd day r = 0.725). LOS and APACHE II on admission were not significantly correlated in the cardiosurgical ICU (APACHE II-1st day r = 0.092), while SOFA on admission and APACHE II and SOFA on third day were significantly correlated (SOFA-1st day r = 0.258; APACHE II-3rd day r = 0.716; SOFA-3rd day r = 0.719). Usefulness of scoring for predicting LOS in ICU varied between different surgical ICUs. Contrary to our hypothesis, scoring had greater value for predicting LOS in the non-specialized general surgical ICU. APACHE II score on admission had no value for predicting LOS in the cardiosurgical ICU.

  15. The chicken vitellogenin II gene is flanked by a GATA factor-dependent estrogen response unit. (United States)

    Davis, D L; Burch, J B


    The chicken vitellogenin II (VTGII) gene is flanked by an imperfect estrogen response element (ERE) at -350 and a perfect ERE at -620. In the present study we show that this imperfect ERE lies within an estrogen response unit (ERU) that requires a GATA factor and the estrogen receptor to function as an estrogen-dependent enhancer. We infer that GATA-6 contributes to the estrogen-dependent and liver-specific regulation of the endogenous VTGII gene since this is the predominant GATA factor expressed in adult liver. Our analysis of the VTGII ERU revealed four salient points. First, this ERU is comprised of an ERE and a bank of functionally redundant GATA-binding sites. Second, the GATA-6 transactivation domain is necessary (and sufficient, when tethered near the ERE) to render this ERU functional. Third, ERU enhancer activity is dependent on GATA 6, regardless of whether the resident ERE is imperfect or perfect. Fourth, in contrast to a report that the estrogen receptor antagonizes the activity of another GATA factor (GATA-1), we show that these two factors can function in a synergistic manner within the context of the VTGII ERU.

  17. China, Japan, and the United States in World War II: The Relinquishment of Unequal Treaties in 1943

    Directory of Open Access Journals (Sweden)

    Xiaohua Ma


    Full Text Available This paper aims to examine how the United States transformed its foreign policy to promote China as an “equal state” in international politics during World War II, with focus on the process of the American relinquishment of its unequal treaties with China in 1943. In particular, it concentrates on analyzing the conflicts between the United States and Japan in the process of relinquishment. By examining the rivalry between the United States and Japan in the social warfare – propaganda – we can see that the relinquishment of the unequal treaties in 1943 not only marked a historical turning point in America’s China policy, but also had a great impact on the transformation of East Asian politics in World War II and its influence in the world politics.

  18. Profile and severity of the patients of intensive care units: prospective application of the APACHE II index. (United States)

    De Freitas, Eliane Regina Ferreira Sernache


    This study aimed to understand the profile and severity of patients in physiotherapy treatment after their admission to the intensive care unit (ICU) by applying the APACHE II index. One hundred and forty six subjects, with a mean age of 60.5 +/- 19.2 years, were evaluated. The APACHE II index was applied in the first 24 hours to evaluate the severity and mortality risk score. Patients were monitored until hospital discharge or death. The mean APACHE II score was 20+/-7.3 with an estimated risk of death of 32.4% and observed mortality of 58.2%. The mean hospital stay was 27.8+/-25.2 days. The patients in physiotherapy at the institution studied were predominantly male, elderly, from the emergency service for treatment (non-surgical), and had clear severity, suggested by the APACHE II score and the observed mortality.

  19. Excitonic connectivity between photosystem II units: what is it, and how to measure it? (United States)

    Stirbet, Alexandrina


    In photosynthetic organisms, light energy is absorbed by a complex network of chromophores embedded in light-harvesting antenna complexes. In photosystem II (PSII), the excitation energy from the antenna is transferred very efficiently to an active reaction center (RC) (i.e., with oxidized primary quinone acceptor Q(A)), where the photochemistry begins, leading to O2 evolution, and reduction of plastoquinones. A very small part of the excitation energy is dissipated as fluorescence and heat. Measurements on chlorophyll (Chl) fluorescence and oxygen have shown that a nonlinear (hyperbolic) relationship exists between the fluorescence yield (Φ(F)) (or the oxygen emission yield, (Φ(O2)) and the fraction of closed PSII RCs (i.e., with reduced Q(A)). This nonlinearity is assumed to be related to the transfer of the excitation energy from a closed PSII RC to an open (active) PSII RC, a process called PSII excitonic connectivity by Joliot and Joliot (CR Acad Sci Paris 258: 4622-4625, 1964). Different theoretical approaches of the PSII excitonic connectivity, and experimental methods used to measure it, are discussed in this review. In addition, we present alternative explanations of the observed sigmoidicity of the fluorescence induction and oxygen evolution curves.

  20. An unprecedented Co(II) cuboctahedron as the secondary building unit in a Co-based metal-organic framework. (United States)

    Holmberg, Rebecca J; Kay, Marika; Korobkov, Ilia; Kadantsev, Eugene; Boyd, Peter G; Aharen, Tomoko; Desgreniers, Serge; Woo, Tom K; Murugesu, Muralee


    A cubic metal-organic framework with an unprecedented octanuclear secondary building unit (SBU) was isolated. The obtained SBU is composed of 8 Co(II) ions at each vertex, 6 μ4-OH groups at each face, and 12 cpt(-) ligands framing the metal core. The cuboctahedra arrange in a ubt framework topology, eliciting a highly symmetrical MOF structure. Magnetic measurements as well as DFT calculations on this crystalline MOF reveal intramolecular antiferromagnetic coupling between Co(II) ions in the octanuclear SBU.

  4. Malpositioned implants in the anterior maxilla: a novel restorative approach to reestablish peri-implant tissue health and acceptable esthetics. Part II: Case report and discussion. (United States)

    Moráguez, Osvaldo D; Vailati, Francesca; Belser, Urs C


    This two-part case presentation describes the prosthetic challenge of managing complications in a 50-year-old female patient after inadequate esthetic risk assessment, treatment planning, and implant placement in the anterior maxilla. In Part I, the clinical situation was described, and different restorative solutions were proposed to correct the extreme facial inclination of the implants, excluding major surgical procedures, namely implant removal. In Part II, different prosthetic options are discussed, and the final treatment is revealed. A noninvasive treatment protocol was applied to transform a severely compromised postsurgical situation into an esthetically acceptable result. An unconventional prosthesis design was implemented, including the use of ceramic veneers bonded to the CAD/CAM-generated screw-retained zirconia- based fixed dental prosthesis (FDP), to correct major axis-related problems and spatial discrepancies.

  6. Visible Light Absorption of Binuclear TiOCoII Charge-Transfer UnitAssembled in Mesoporous Silica

    Energy Technology Data Exchange (ETDEWEB)

    Han, Hongxian; Frei, Heinz


    Grafting of CoII(NCCH3)2Cl2 onto mesoporous Ti-MCM-41 silicain acetonitrile solution affords binuclear Ti-O-CoII sites on the poresurface under complete replacement of the precursor ligands byinteractions with anchored Ti centers and the silica surface. The CoIIligand field spectrum signals that the Co centers are anchored on thepore surface in tetrahedral coordination. FT-infrared action spectroscopyusing ammonia gas adsorption reveals Co-O-Si bond modes at 831 and 762cm-1. No Co oxide clusters are observed in the as-synthesized material.The bimetallic moieties feature an absorption extending from the UV intothe visible to about 600 nm which is attributed to the TiIV-O-CoII?3TiIII-O-CoIII metal-to-metal charge-transfer (MMCT) transition. Thechromophore is absent in MCM-41 containing Ti and Co centers isolatedfrom each other; this material was synthesized by grafting CoII onto aTi-MCM-41 sample with the Ti centers protected by a cyclopentadienylligand. The result indicates that the appearance of the charge-transferabsorption requires that the metal centers are linked by an oxo bridge,which is additionally supported by XANES spectroscopy. The MMCTchromophore of Ti-O-CoII units has sufficient oxidation power to serve asvisible light electron pump for driving multi-electron transfer catalystsof demanding uphill reactions such as water oxidation.

  7. Two new hexacoordinated coordination polymers of cadmium(II) containing bridging units only: Syntheses, structures and molecular properties

    Indian Academy of Sciences (India)



    The syntheses, characterizations and structures of a neutral 2D coordination polymer [Cd(bnzd)(NCS)₂]n (1) and a polycationic 3D coordination polymer isolated as perchlorate salt [Cd(bnzd)₃]n(ClO₄)₂n (2) (bnzd = benzidine) are described. X-ray structural analyses reveal that each hexacoordinated cadmium(II) center in 1 adopts a distorted octahedral geometry with a CdN₄S₂ chromophore bound by two N atoms of two different bnzd units and two N and two S atoms of symmetric doubly bridged end-toend NCS− units extended in a 2D sheet. Six N atoms of six different bridged bnzd units are bonded to each cadmium(II) in 2 in a non-ended fashion affording a 3D network structure. In the crystalline state, each 2D sheet structure in 1 is further stabilized by π· · ·π interaction which in turn affords a 3D network structure through multiple intermolecular N-H· · · S hydrogen bonds. On the other hand, the 3D network structure in 2 is stabilized by weak intermolecular N-H· · ·O hydrogen bonds and C-H· · ·π interactions. Bnzd, 1 and 2 display intraligand 1(π-π*) fluorescence in DMF solution at room temperature.

    Diana J. Arya


    Full Text Available Global efforts to prepare young developing minds for solving current and future challenges of climate change have advocated interdisciplinary, issues-based instructional approaches in order to transform traditional models of science education as delivering conceptual facts (UNESCO, 2014. This study is an exploration of the online interactions in an international social network of high school students residing in Norway, China, New Zealand and the United States (N=141. Students participated in classroom-based and asynchronous online discussions about adapted versions of seminal scientific studies with facilitative support from seven scientists across various fields. Grounded in a language-in-use frame for investigating facilitation and demonstrations of problem-based and evidence-based reasoning (Kelly & Chen, 1999, we traced the varied questions, assertions, and evidentiary sources within student-led online discussions. We found that questions from scientific experts in the form of unconstrained, open-ended invitations for exploration were followed by students’ acknowledgement and consideration of complex and, at times, conflicting sociopolitical and economic positions about climate change issues. These findings suggest that broadening science classroom discussions to include socially relevant, unsolved issues like climate change could open potential entry points for a dialogic approach that fosters a scientific community in the classroom.

  10. Is nickel allergy an occupational disease? Discussion of the occupational relevance of a type IV allergy to nickel (II) sulfate using case reports. (United States)

    Tanko, Zita; Diepgen, Thomas L; Weisshaar, Elke


    Type IV sensitization to nickel (II) sulfate is common in the general population. Nickel can be found in different metals leading to occupational exposition in industrial professions. The individual clinical relevance of nickel allergy can easily be identified but it can be difficult to assess if nickel allergy was acquired privately or occupationally. The problem if nickel allergy fulfills the criteria of an occupational skin disease is presented in three case reports. The occupational relevance of a type IV sensitization to nickel in a chemical laboratory assistant, a flight attendant and a cashier are discussed. Important conditions for acquiring nickel allergy are contact with nickel-plated and nickel-releasing materials, the kind of skin contact, the status of the epidermal barrier, and the individual working conditions with an increased bioavailability of nickel. In cases of type IV sensitization to nickel, the affected person cannot continue to work in metal plating or with contact to nickel-plated metals. The causal relationship between the type IV sensitization to nickel and the occupation needs to be clarified in each individual case. In general, occupationally caused nickel allergy is rare and the occupational relevance of nickel allergy is often overestimated.

  14. [APACHE II and ATN-ISS in acute renal failure (ARF) in intensive care unit (ICU) and non-ICU]. (United States)

    Fernandes, Natáia Maria da Silva; Pinto, Patrícia dos Santos; Lacet, Thiago Bento de Paiva; Rodrigues, Dominique Fonseca; Bastos, Marcus Gomes; Stella, Sérgio Reinaldo; Cendoroglo Neto, Miguel


    Acute renal failure (ARF) remains highly prevalent with a high rate of morbidity and mortality. of this study was to compare use of the APACHE II scoring prognosis with that of the ATN-ISS to determine whether the APACHE II could be used for patients with ARF outside the ICU. For this purpose, 205 patients with ARF were accompanied in a prospective cohort. Demographic data, preexisting conditions, organ failure and characteristics of ARF were analyzed. The prognostic scores were performed with the assessment of a nephrologist. The mean age was 52 +/- 18 years, 50% were male, 69% were white, 45% were treated in ICU and 55% in other units. Mortality in the ICU group was 85% and in the non-ICU group 18%. Factors that correlated with higher mortality were more prevalent in the ICU group: age, male, hospitalization with ARF, organ failure, sepsis, septic IRA, oliguria and need of dialysis. Overall, the prognostic markers were the same for both the ICU and non-ICU groups. The discrimination with the APACHE II was similar in both, ICU and non-ICU groups and calibration was better in the non-ICU group. The ATN-ISS achieved good discrimination in both the ICU and non-ICU groups, but, regarding calibration, there was a discreet over estimating of mortality in the non-ICU group. The ATN-ISS showed a greater capacity for discrimination than the APACHE II in both the ICU and non-ICU groups. It was concluded that the APACHE II and ATN-ISS scores could be used for stratification of risk in patients with ARF treated outside of the ICU in Brazil.

  15. Joseph S. Weiner and the foundation of post-WW II human biology in the United Kingdom. (United States)

    Little, Michael A; Collins, Kenneth J


    Both the United States and the United Kingdom experienced a transformation in the science of physical anthropology from the period before World War II until the post-war period. In the United States, Sherwood L. Washburn is credited with being a leading figure in this transformation. In the United Kingdom, two individuals were instrumental in bringing about a similar change in the profession. These were Joseph S. Weiner at the University of Oxford and Nigel Barnicot at the University of London, with Weiner playing the principal role as leader in what Washburn called the "New Physical Anthropology," that is, the application of evolutionary theory, the de-emphasis on race classification, and the application of the scientific method and experimental approaches to problem solving. Weiner's contributions to physical anthropology were broad-based--climatic and work physiology, paleoanthropology, and human variation--in what became known as human biology in the U.K. and human adaptability internationally. This biographical essay provides evidence for the significant influence of J.S. Weiner on the post-war development of human biology (biological or physical anthropology) inthe U.K.

  16. Gene expression of herpes simplex virus. II. Uv radiological analysis of viral transcription units

    Energy Technology Data Exchange (ETDEWEB)

    Millette, R. L.; Klaiber, R.


    The transcriptional organization of the genome of herpes simplex virus type 1 was analyzed by measuring the sensitivity of viral polypeptide synthesis to uv irradiation of the infecting virus. Herpes simplex virus type 1 was irradiated with various doses of uv light and used to infect xeroderma pigmentosum fibroblasts. Immediate early transcription units were analyzed by having cycloheximide present throughout the period of infection, removing the drug at 8 h postinfection, and pulse-labeling proteins with (355)methionine. Delayed early transcription units were analyzed in similar studies by having 9-beta-D-arabinofuranosyladenine present during the experiment to block replication of the input irradiated genome. The results indicate that none of the immediate early genes analyzed can be cotranscribed, whereas some of the delayed early genes might be cotranscribed. No evidence was found for the existence of large, multigene transcription units.

  7. Free-Piston Stirling Power Conversion Unit for Fission Power System, Phase II Final Report (United States)

    Wood, J. Gary; Stanley, John


    In Phase II, the manufacture and testing of two 6-kW(sub e)Stirling engines was completed. The engines were delivered in an opposed 12-kW(sub e) arrangement with a common expansion space heater head. As described in the Phase I report, the engines were designed to be sealed both hermetically and with a bolted O-ring seal. The completed Phase II convertor is in the bolted configuration to allow future disassembly. By the end of Phase II, the convertor had passed all of the final testing requirements in preparation for delivery to the NASA Glenn Research Center. The electronic controller also was fabricated and tested during Phase II. The controller sets both piston amplitudes and maintains the phasing between them. It also sets the operating frequency of the machine. Details of the controller are described in the Phase I final report. Fabrication of the direct-current to direct-current (DC-DC) output stage, which would have stepped down the main controller output voltage from 700 to 120 V(sub DC), was omitted from this phase of the project for budgetary reasons. However, the main controller was successfully built, tested with the engines, and delivered. We experienced very few development issues with this high-power controller. The project extended significantly longer than originally planned because of yearly funding delays. The team also experienced several hardware difficulties along the development path. Most of these were related to the different thermal expansions of adjacent parts constructed of different materials. This issue was made worse by the large size of the machine. Thermal expansion problems also caused difficulties in the brazing of the opposed stainless steel sodium-potassium (NaK) heater head. Despite repeated attempts Sunpower was not able to successfully braze the opposed head under this project. Near the end of the project, Glenn fabricated an opposed Inconel NaK head, which was installed prior to delivery for testing at Glenn. Engine

  8. Removal of Cu(II) ions by biosorption onto powdered waste sludge (PWS) prior to biological treatment in an activated sludge unit: a statistical design approach. (United States)

    Pamukoglu, M Yunus; Kargi, Fikret


    Biological treatment of synthetic wastewater containing Cu(II) ions was realized in an activated sludge unit with pre-adsorption of Cu(II) onto powdered waste sludge (PWS). Box-Behnken experimental design method was used to investigate Cu(II), chemical oxygen demand (COD) and toxicity removal performance of the activated sludge unit under different operating conditions. The independent variables were the solids retention time (SRT, 5-30 d), hydraulic residence time (HRT, 5-25 h), feed Cu(II) concentration (0-50 mg L(-1)) and PWS loading rate (0-4 g h(-1)) while percent Cu(II), COD, toxicity (TOX) removals and the sludge volume index (SVI) were the objective functions. The data were correlated with a quadratic response function (R2=0.99). Cu(II), COD and toxicity removals increased with increasing PWS loading rate and SRT while decreasing with the increasing feed Cu(II) concentration and HRT. Optimum conditions resulting in maximum Cu(II), COD, toxicity removals and SVI values were found to be SRT of 30 d, HRT 15 h, PWS loading rate 3 g h(-1) and feed Cu(II) concentration of less than 30 mg L(-1).

  9. Aiming to be a breastfeeding mother in a neonatal intensive care unit and at home: a thematic analysis of peer-support group discussion in social media. (United States)

    Niela-Vilén, Hannakaisa; Axelin, Anna; Melender, Hanna-Leena; Salanterä, Sanna


    Preterm infants are usually breastfed less than full-term infants, and successful breastfeeding requires a supportive environment and special efforts from their mothers. A breastfeeding peer-support group, utilising social media, was developed for these mothers in order to support them in this challenge. Mothers were able to discuss breastfeeding and share experiences. The purpose of this study was to describe the perceptions of breastfeeding mothers of preterm infants based on the postings in peer-support group discussions in social media. The actively participating mothers (n = 22) had given birth <35 gestational weeks. They were recruited from one university hospital in Finland. The social media postings (n = 305) were analysed using thematic analysis. A description of the process of breastfeeding a preterm infant from the point of view of a mother was created. The process consisted of three main themes: the breastfeeding paradox in hospital, the 'reality check' of breastfeeding at home and the breastfeeding experience as part of being a mother. The mothers encountered paradoxical elements in the support received in hospital; discharge was promoted at the expense of breastfeeding and pumping breast milk was emphasised over breastfeeding. After the infant's discharge, the over-optimistic expectations of mothers often met with reality - mothers did not have the knowledge or skills to manage breastfeeding at home. Successful breastfeeding was an empowering experience for the mothers, whereas unsuccessful breastfeeding induced feelings of disappointment. Therefore, the mothers of preterm infants need evidence-based breastfeeding counselling and systematic support in a neonatal intensive care unit (NICU) and at home. © 2014 John Wiley & Sons Ltd.

    Let K be a field of characteristic 2 and G a non-abelian locally finite 2-group. Let V(KG) be the group of units with augmentation 1 in the group algebra KG. An explicit list of groups is given, and it is proved that all involutions in V(KG) commute with each other if and only if G is isomorphic to one of the groups on this list. In particular, this property depends only on G and does not depend on K.

  11. Cardiovascular and single-unit responses to microinjection of angiotensin II into the bed nucleus of the stria terminalis in rat. (United States)

    Kafami, M; Nasimi, A


    The bed nucleus of the stria terminalis (BST) is part of the limbic system located in the rostral forebrain. BST is involved in behavioral, neuroendocrine and autonomic functions, including cardiovascular regulation. The angiotensin II (Ang II) receptor, AT1, was found in the BST, however its effects on the cardiovascular system and on single-unit responses have not been studied yet. In the present study, Ang II was microinjected into the BST of anesthetized rats and cardiovascular and single-unit responses were recorded simultaneously. Furthermore the responses were re-tested after the microinjection of a blocker of the AT1 receptor, losartan, into the BST. We found that microinjection of Ang II into the BST produced a pressor response of 11±1mmHg for a duration of 2-8min. Ang II had no consistent effect on heart rate. It also produced two types of single-unit responses in the BST, short excitatory and long inhibitory. Blockade of AT1 receptors abolished both the cardiovascular and single-unit responses, indicating that the responses were mediated through AT1 receptors. These findings imply that Ang II may be utilized as a neurotransmitter and may play a role in returning blood pressure toward normal during hypotension. Copyright © 2015 IBRO.

  12. Explicit isospectral flows associated to the AKNS operator on the unit interval. II (United States)

    Amour, Laurent


    Explicit flows associated to any tangent vector fields on any isospectral manifold for the AKNS operator acting in L2 × L2 on the unit interval are written down. The manifolds are of infinite dimension (and infinite codimension). The flows are called isospectral and also are Hamiltonian flows. It is proven that they may be explicitly expressed in terms of regularized determinants of infinite matrix-valued functions with entries depending only on the spectral data at the starting point of the flow. The tangent vector fields are decomposed as ∑ξkTk where ξ ∈ ℓ2 and the Tk ∈ L2 × L2 form a particular basis of the tangent vector spaces of the infinite dimensional manifold. The paper here is a continuation of Amour ["Explicit isospectral flows for the AKNS operator on the unit interval," Inverse Probl. 25, 095008 (2009)], 10.1088/0266-5611/25/9/095008 where, except for a finite number, all the components of the sequence ξ are zero in order to obtain an explicit expression for the isospectral flows. The regularized determinants induce counter-terms allowing for the consideration of finite quantities when the sequences ξ run all over ℓ2.

Weather variables summarized include dry bulb and wet bulb temperature, percent relative humidity, humidity ratio, wind speed, percent possible sunshine, percent diffuse solar radiation, total solar radiation on horizontal and vertical surfaces, and solar heat gain through standard DSA glass. Monthly and annual summaries, in some cases by time of day, are available. These summaries are produced in a series of nine computer generated tables.

  14. New macrocyclic schiff base complexes incorporating a homopiperazine unit: Synthesis of some Co(II), Ni(II),Cu(II) and Zn(II) complexes and crystal structure and theoretical studies (United States)

    Keypour, Hassan; Rezaeivala, Majid; Ramezani-Aktij, Ameneh; Bayat, Mehdi; Dilek, Nefise; Ünver, Hüseyin


    A new macrocyclic Schiff base ligand, L, was synthesized by condensation reaction of 1,4-bis(2-formylphenyl)homopiperazine and 1,4-diaminobutane in acetonitrile. The Schiff base ligand was characterized by using elemental analyses, FT-IR, 1H, 13C NMR and mass spectroscopic techniques. The metal (II) complexes [ML], were synthesized from the reaction of MCl2.nH2O (M: Co, Ni, Cu and Zn) with Schiff base ligand, L and characterized by elemental analyses and FT-IR. X-ray crystal structure of [CoLCl]+ distorted square pyramidal geometry with an N4Cl core, arising from coordination by the four donor nitrogen atoms from the macrocyclic framework and one Cl atom. It crystallizes triclinic space group, P-1 with a = 7.1777(1) Å, b = 11.0357 (2) Å, c = 15.1520(2) Å, V = 1183.14(3), Z = 2, Dc = 1.556 g cm-3, μ (MoKα) = 0.156 mm-1. Also, the bonding situation between the [MCl]+ and Ligand (L) fragments in [MLCl]ClO4 (M = Co(II), Ni(II), Cu(II), Zn(II)) complexes were carried out by energy-decomposition analysis (EDA). The results showed that there is an increasing trend in the case of ΔEelstat of the complexes by changing the M from Co(II) to Zn(II).

    To analyse the evolution of care provided by the internal medicine units (IMU) of the Spanish National Health System from 2007 to 2014. We analysed all discharges from the IMU of the Spanish National Health System in 2007 and 2014, using the Minimum Basic Data Set. We compared the risk factors by episode, mortality and readmissions between the two periods. We prepared specific fits for the risk for mortality and readmissions in heart failure, pneumonia and chronic obstructive pulmonary disease, as well as the Charlson index for all activity. Discharges from the IMU between the two periods increased 14%. The average patient age increased by 2.8 years (71.2±17.1 vs. 74±16.2; pMedicina Interna (SEMI). All rights reserved.

  16. On the Edge of Life, II: House Officer Struggles Recorded in an Intensive Care Unit Journal. (United States)

    Sekeres, Mikkael A.; Stern, Theodore A.


    BACKGROUND: In a general hospital, few clinical settings match the intensity of the intensive care unit (ICU) experience. Clinical rotations in ICUs elicit and emphasize the struggles house officers face on a daily basis throughout their training. METHOD: These struggles were recorded by hundreds of residents in a journal maintained in one Medical ICU for the past 20 years. We systematically reviewed these unsolicited entries to develop categories that define and illustrate common stressors. RESULTS: Stressors for house officers include isolation, insecurity, care for the terminally ill, sleep deprivation, and long work weeks. CONCLUSION: By placing the struggles of house staff in context, trainees and their residency training programs can be prepared for the intensity of the experience and for work in clinical practice settings that follows completion of training.

    Ebani, Patrícia Regina; Fontana, Liniquer Andre; Campos, Patrick Teixeira; Rosso, Eduardo F.; Piquini, Paulo C.; Iglesias, Bernardo Almeida; Back, Davi Fernando


    We have reported the synthesis involving the condensation of pyridoxal with tris(2-aminoethyl)amine obtained a tripodal ligand, as well as its subsequent complexation with the manganese(II) and nickel(II) ions. The structural analysis revealed, in the case of complex 1, the formation of a monomeric complex with Mn(II) species. In the complex 2, with Ni(II) metal ion, we describe the probable mechanism for the formation of hemiacetal in these complexes. Only the complex 1 catalyze the dismutation of superoxide efficiently with IC50 equal to 3.38 μM, evaluated through the nitro blue tetrazolium photoreduction inhibition superoxide dismutase assay, in aqueous solution of pH 7.8. Density functional theory calculations are done to characterize and compare the molecular frontier orbitals of the Mn(II) and Ni(II) complexes.

    Kinhikar Rajesh


    Full Text Available Purpose : To characterize metal oxide semiconductor field-effect transistors (MOSFETs for a 6-MV photon beam with a first helical tomotherapy Hi-Art II unit in India. Materials and Methods : Standard sensitivity MOSFETs were first calibrated and then characterized for reproducibility, field size dependence, angular dependence, fade effects, and temperature dependence. The detector sensitivity was estimated for static as well as rotational modes for three jaw settings (1.0 cm × 40 cm, 2.5 cm × 40 cm, and 5 cm × 40 cm at 1.5-cm depth with a source-to-axis distance (SAD of 85 cm in virtual water slabs. The A1SL ion chamber and thermoluminescence dosimeters (TLDs were used to compare the results. Results : No significant difference was found in the detector sensitivity for static and rotational procedures. The average detector sensitivity for static procedures was 1.10 mV/cGy (SD 0.02 while it was 1.12 mV/cGy (SD 0.02 for rotational procedures. The average detector sensitivity found was the same within the experimental uncertainty for static and rotational dose deliveries. The MOSFET reading was consistent and its reproducibility was excellent (+0.5% while there was no significant dependence of field size. The angular dependence of less than 1.0% was observed. There was negligible fading effect of the MOSFET. The MOSFET response was found independent of temperature in the range 18°-30°. The ion chamber readings were assumed to be a reference for the estimation of the MOSFET calibration factor. The ion chamber and the TLD were in good agreement (+2% with each other. Conclusion : This study deals only with the measurements and calibration performed on the surface of the phantom. MOSFET was calibrated and validated for phantom surface measurements for a 6-MV photon beam generated by a tomotherapy machine. The sensitivity of the detector was the same for both modes of treatment delivery with tomotherapy. The performance of the MOSFET was validated

  8. Development of a novel walkability index for London, United Kingdom: cross-sectional application to the Whitehall II Study. (United States)

    Stockton, Jemima C; Duke-Williams, Oliver; Stamatakis, Emmanuel; Mindell, Jennifer S; Brunner, Eric J; Shelton, Nicola J


    Physical activity is essential for health; walking is the easiest way to incorporate activity into everyday life. Previous studies report positive associations between neighbourhood walkability and walking but most focused on cities in North America and Australasia. Urban form with respect to street connectivity, residential density and land use mix-common components of walkability indices-differs in European cities. The objective of this study was to develop a walkability index for London and test the index using walking data from the Whitehall II Study.  A neighbourhood walkability index for London was constructed, comprising factors associated with walking behaviours: residential dwelling density, street connectivity and land use mix. Three models were produced that differed in the land uses included. Neighbourhoods were operationalised at three levels of administrative geography: (i) 21,140 output areas, (ii) 633 wards and (iii) 33 local authorities. A neighbourhood walkability score was assigned to each London-dwelling Whitehall II Study participant (2003-04, N = 3020, mean ± SD age = 61.0 years ± 6.0) based on residential postcode. The effect of changing the model specification and the units of enumeration on spatial variation in walkability was examined. There was a radial decay in walkability from the centre to the periphery of London. There was high inter-model correlation in walkability scores for any given neighbourhood operationalisation (0.92-0.98), and moderate-high correlation between neighbourhood operationalisations for any given model (0.39-0.70). After adjustment for individual level factors and area deprivation, individuals in the most walkable neighbourhoods operationalised as wards were more likely to walk >6 h/week (OR = 1.4; 95 % CI: 1.1-1.9) than those in the least walkable. Walkability was associated with walking time in adults. This walkability index could help urban planners identify and design neighbourhoods in

    Gregg Ruskuaff


    This document, the Phase II Frenchman Flat transport report, presents the results of radionuclide transport simulations that incorporate groundwater radionuclide transport model statistical and structural uncertainty, and lead to forecasts of the contaminant boundary (CB) for a set of representative models from an ensemble of possible models. This work, as described in the Federal Facility Agreement and Consent Order (FFACO) Underground Test Area (UGTA) strategy (FFACO, 1996; amended 2010), forms an essential part of the technical basis for subsequent negotiation of the compliance boundary of the Frenchman Flat corrective action unit (CAU) by Nevada Division of Environmental Protection (NDEP) and National Nuclear Security Administration Nevada Site Office (NNSA/NSO). Underground nuclear testing via deep vertical shafts was conducted at the Nevada Test Site (NTS) from 1951 until 1992. The Frenchman Flat area, the subject of this report, was used for seven years, with 10 underground nuclear tests being conducted. The U.S. Department of Energy (DOE), NNSA/NSO initiated the UGTA Project to assess and evaluate the effects of underground nuclear tests on groundwater at the NTS and vicinity through the FFACO (1996, amended 2010). The processes that will be used to complete UGTA corrective actions are described in the “Corrective Action Strategy” in the FFACO Appendix VI, Revision No. 2 (February 20, 2008).

    Full Text Available Introduction. In developing countries, a lack of decentralization of perinatal care leads to many high-risk births occurring in facilities that do not have NICU, leading to admission to a PICU. Objective. To assess SNAP II and SNAPPE II as predictors of neonatal death in the PICU. Methodology. A prospective study of newborns divided into 3 groups according to postnatal age: Group 1 (G1, of 0 to 6 days; Group 2 (G2 of 7 to 14 days; and Group 3 (G3, of 15 to 28 days. Variables analyzed were SNAP II, SNAPPE II, perinatal data, and known risk factors for death. The Hosmer-Lemeshow test and the receiver operating characteristics (ROC curve were used with SPSS 17.0 for statistical analysis. An Alpha error <5% was considered significant. Results. We analyzed 290 newborns, including 192 from G1, 41 from G2, and 57 from G3. Mortality was similar in all 3 groups. Median SNAP II was higher in newborns that died in all 3 groups (P<0.05. The area under the ROC curve for SNAP II for G1 was 0.78 (CI 95% 0.70–0.86, for G2 0.66 (CI 95% 0.37–0.94, and for G3 0.74 (CI 95% 0.53–0.93. The area under the ROC curve for SNAPPE II for G1 was 0.76 (CI 95% 0.67–0.85, for G2 0.60 (CI 95% 0.30–0.90, and for G3 0.74 (CI 95% 0.52–0.95. Conclusions. SNAP II and SNAPPE II showed moderate discrimination in predicting mortality. The results are not strong enough to establish the correlation between the score and the risk of mortality.

    Full Text Available As estreitas relações militares entre o Brasil e os Estados Unidos deterioraram-se no período imediatamente após à II Guerra Mundial. As divisões associadas à Guerra Fria criaram pressões nacionais e internacionais que levaram a um relacionamento menos preciso e sempre reativo entre os dois gigantes do hemisfério. Quando havia uma convergência de metas, as relações militares refletiam a cooperação amistosa anterior. Quando divergências políticas e institucionais sobre questões bilaterais emergiam, o Brasil recusava-se a seguir a liderança norte-americana. Em larga medida, a política externa no pós-guerra obrigou o Brasil a desenvolver confiança e habilidade para acabar com a prática tradicional de agir como subordinado de um poderoso protetor. O processo começou com a assistência norte-americana para a criação da Escola Superior de Guerra e culminou em 1977 com o fim das relações militares com os EUA (com a denúncia do acordo militar com os EUA. Dessa forma, o Brasil conquistou parte do seu antigo desejo de grandeza.The close military relations between the Brazil and the United States underwent strains in the early post-war era. Cold War divisions created national and international pressures that led to a less precise and often reactive relationship between the hemisphere giants. When there was a convergence of goals, military relations reflected the previous smooth cooperation. When political and institutional divisiveness emerged in the officer corps over bilateral issues, Brazil refused to follow the U.S. lead. To a large degree, the post-war foreign policy forced Brazil and its military establishment to develop the confidence and ability to end the traditional practice of acting as a surrogate for a more powerful patron. The process began with U.S. assistance in creating the Escola Superior de Guerra and culminated in 1977 with the end of formal military relations with the United States. In so doing, Brazil

  19. Prediction of outcome from intensive care: a prospective cohort study comparing Acute Physiology and Chronic Health Evaluation II and III prognostic systems in a United Kingdom intensive care unit. (United States)

    Beck, D H; Taylor, B L; Millar, B; Smith, G B


    To evaluate the ability of two prognostic systems to predict hospital mortality in adult intensive care patients. Prospective cohort study. A mixed medical and surgical intensive care unit (ICU) in the United Kingdom. A total of 1,144 patients consecutively admitted to the study. None. Acute Physiology and Chronic Health Evaluation (APACHE) II and III prognostic systems were applied to assess probabilities of hospital mortality, which were compared with the actual outcome. The overall goodness-of-fit of both models was assessed. Hospital death rates were higher than those predicted by each system. Risk estimates showed a strong positive correlation between both systems (nonsurvivors r2 = 0.756, p best overall total correct classification rate was 80.6% for APACHE III and 77.9% for APACHE II (both for a decision criterion of 40%). The areas under the receiver operating characteristic curves were 0.806 and 0.847 for APACHE II and III, respectively, confirming the better discrimination of APACHE III. When patients were classified by diagnostic categories, risk predictions did not fit uniformly across the spectrum of disease groups. For both models, mortality ratios were highest for trauma patients and lowest for the group with respiratory disease. APACHE II predictions for patients with gastrointestinal disease were significantly better. Risk estimates for surgical admissions were superior with APACHE II (MR = 1.27) compared with APACHE III (MR = 1.56), but were similar for medical patients (1.22 vs. 1.28 for APACHE II and III, respectively). Bias induced by factors reflecting the clinical practice in an individual ICU (e.g., admission criteria, treatment before admission) may have considerable impact on risk estimates. The identification of such factors appears to be a prerequisite for the meaningful interpretation of observed and predicted death rates on the individual ICU level. Both predictive models demonstrated a similar degree of overall goodness-of-fit. APACHE

  4. Management strategies to effect change in intensive care units: lessons from the world of business. Part II. Quality-improvement strategies. (United States)

    Gershengorn, Hayley B; Kocher, Robert; Factor, Phillip


    The success of quality-improvement projects relies heavily on both project design and the metrics chosen to assess change. In Part II of this three-part American Thoracic Society Seminars series, we begin by describing methods for determining which data to collect, tools for data presentation, and strategies for data dissemination. As Avedis Donabedian detailed a half century ago, defining metrics in healthcare can be challenging; algorithmic determination of the best type of metric (outcome, process, or structure) can help intensive care unit (ICU) managers begin this process. Choosing appropriate graphical data displays (e.g., run charts) can prompt discussions about and promote quality improvement. Similarly, dashboards/scorecards are useful in presenting performance improvement data either publicly or privately in a visually appealing manner. To have compelling data to show, ICU managers must plan quality-improvement projects well. The second portion of this review details four quality-improvement tools-checklists, Six Sigma methodology, lean thinking, and Kaizen. Checklists have become commonplace in many ICUs to improve care quality; thinking about how to maximize their effectiveness is now of prime importance. Six Sigma methodology, lean thinking, and Kaizen are techniques that use multidisciplinary teams to organize thinking about process improvement, formalize change strategies, actualize initiatives, and measure progress. None originated within healthcare, but each has been used in the hospital environment with success. To conclude this part of the series, we demonstrate how to use these tools through an example of improving the timely administration of antibiotics to patients with sepsis.

    The reaction of bis(1,2,4-triazolyl-4-yl) (btr) and MnClO4-6H20 gave rise to a Mn(II) complex comprised of unprecedented dinuclear Mn(II) units, {[Mn2(btr)s(H20)5]- (ClO4)4(H20)2]n (1). Single-crystal X-ray diffraction analysis revealed that 1 crystallizes in the monoclinic space group C2/c. btr adopts two types of bridging modes. One serves as μ-N1 :N2 bridge through one triazolyl ring of btr forming a dinuclear Mn(II) unit, and the other adopts an exo-bidentate mode using two nitrogen atoms from each triazolyl ring and links the dinuclear units into a 2D cationic layer. ClO4 acts as a counter anion and does not take part in coordination. Interestingly, 2D layers are packed in an ABCABC mode. ClO4- and uncoordinated water molecules locate between the adjacent layers, and extensive hydrogen bonds further stabilize the whole framework.

  10. Discussion on Evaluation Methods for Corrosion Inhibitors Used in Delayed Coking Unit%延迟焦化装置缓蚀剂评价方法探讨

    张贵英; 宫红; 姜恒


    Delayed coking process is the primary means for deep processing of residue. However, large amounts of hydrogen sulfide gas produced in this process will dissolved in coking wastewater. H2S ionizes in a humid environment to form a galvanic cell with elemental iron, which can cause serious corrosion of equipments. Corrosion inhibitor is often used to slow down the corrosion of the unit. Currently, the content of Fe2+ in coking wastewater is the major evaluation index of inhibitor. Usually, the content of Fe2+ should be less than 3.0 mg/L. In this paper, content of Fe2+ dissolved in wastewater under different conditions was calculated by the solubility product of FeS. The results show that the content of Fe2+in wastewater even without inhibitor is less than 3.0 mg/L which was provided in existing regulations. More reliable methods to evaluate the corrosion are the corrosion coupon or corrosion probe suspended in the pipeline or equipment and its monitoring data can embody the real corrosion condition.%延迟焦化工艺是目前渣油深度加工的主要手段,但在加工过程中会产生大量硫化氢气体并溶解于焦化酸性水中。在湿硫化氢环境中,硫化氢会电离,并与单质铁发生原电池反应,从而对设备造成严重腐蚀,常采用添加缓蚀剂的方法来减缓其对装置的腐蚀。目前评价缓蚀剂性能的指标是检测焦化酸性水中的铁离子含量,通常规定焦化酸性水中铁含量应小于3.0 mg/L。通过FeS的溶度积,计算了不同pH值、不同H2S含量的水溶液中 Fe2+的含量。结果显示:即使不添加缓蚀剂,焦化酸性水中 Fe2+的理论最大浓度也不会高于现行标准中所规定的3.0 mg/L。比较可靠的缓蚀评价方法是将腐蚀挂片或腐蚀探针悬挂于管道设备内部,其监测数据能够比较真实体现腐蚀状况。

  11. Magnetic ordering in two molecule-based (10,3)-a nets prepared from a copper(II) trinuclear secondary building unit. (United States)

    Gil-Hernández, Beatriz; Gili, Pedro; Vieth, Jana K; Janiak, Christoph; Sanchiz, Joaquín


    Two new molecule-based materials of formulas 3D-{[K(H(2)O)(6)](0.5)[K(18-crown-6)](0.5)[MnCu(3)(Hmesox)(3)].5.25H(2)O} (1) and 3D-{(Ph(4)P)(2)[MnCu(3)(Hmesox)(3)Cl].3.5H(2)O} (2) have been prepared from a tricopper(II) secondary building unit (SBU), [Cu(3)(Hmesox)(3)](3-) (H(4)mesox = mesoxalic acid, 2-dihydroxymalonic acid). Compound 1 is obtained by means of the reaction of the SBU with manganese(II) acetate in the presence of potassium cations and the 18-crown-6 ether, whereas compound 2 is obtained by means of the reaction of the SBU with manganese(II) acetate in the presence of Ph(4)PCl. The [MnCu(3)(Hmesox)(3)](-) and [MnCu(3)(Hmesox)(3)Cl](2-) moieties in compounds 1 and 2, respectively, yield chiral 3-connected three-dimensional (3D) anionic (10,3)-a (srs, SrSi(2)) nets. In the cubic and centrosymmetric structures (Pa3) of 1, two inversion-symmetry-related anion nets interpenetrate to a racemic structure. The Ph(4)P(+) cations in 2 are organized in a supramolecular (10,3)-a net through the 6-fold phenyl embrace. In 2, both the cationic and anionic nets are homochiral and enantiopure with opposite handedness and form interpenetrating supramolecular and covalent (10,3)-a nets in the noncentrosymmetric Sohncke space group P 2(1)2(1)2(1). Both compounds display ferrimagnetic interaction with long-range magnetic ordering below 2.5 and 15.2 K for 1 and 2, respectively. A dehydrated phase of 2 exhibits a T(c) of 21.8 K. The saturation of magnetization, M(S), indicates two different ground states, S = (1)/(2) and (3)/(2), for the tricopper(II) units in 1 and 2, respectively. The different spin states of the tricopper(II) unit in 1 and 2 has been explained by means of a density functional theory (DFT) study performed in the [Cu(3)(Hmesox)(3)](3-) and [Cu(3)(Hmesox)(3)Cl](4-) fragments, for 1 and 2, respectively. A further DFT study has allowed one to analyze the structural parameters that lead to the different spin ground states for the trinuclear units in both

    The object of this study is the validation of WIMS-AECL lattice code which has been proposed for the substitution of POWDERPUFS-V(PPV) code. For the validation of this code, WIMS-AECL/(MULTICELL)/RFSP (lattice calculation/(incremental cross section calculation)/core calculation) code system has been used for the Post-Simulation of Phase-B physics Test at Wolsung-II unit. This code system had been used for the Wolsong-I and Point Lepraeu reactors, but after a few modifications of WIMS-AECL input values for Wolsong-II, the results of WIMS-AECL/RFSP code calculations are much improved to those of the old ones. Most of the results show good estimation except moderator temperature coefficient test. And the verification of this result must be done, which is one of the further work. 6 figs., 15 tabs. (Author)

Documentary research that addressed quantitatively the nursing diagnosis proposed using the Taxonomy II of NANDA-I (2009-2011. It was documented 82 different diagnosis, and covered all the 13 domains. The involvement of all the domains and the large variability of diagnoses identified suggested a possible holistic view of patient care and emphasized the individuality of the care plan. However, it may indicate an immaturity of these students, because often different diagnosis are related, and interventions set to one of these can solve the other, so opting for one avoids large health plans. Researchers and professors should conduct investigations and discussions to be identified teaching methods best suited to the teaching of the diagnostic process.

  6. Multi-unit inertial fusion plants based on HYLIFE-II, with shared heavy-ion RIA driver and target factory, producing electricity and hydrogen fuel

    Energy Technology Data Exchange (ETDEWEB)

    Logan, G.; Moir, R. [Lawrence Livermore National Lab., CA (United States); Hoffman, M. [Univ. of California, Davis, CA (United States)


    Following is a modification of the IFEFUEL systems code, called IFEFUEL2, to treat specifically the HYLIFE-II target chamber concept. The same improved Recirculating Induction Accelerator (RIA) energy scaling model developed recently by Bieri is used in this survey of the economics of multi-unit IFE plants producing both electricity and hydrogen fuel. Reference cases will assume conventional HI-indirect target gains for a 2 mm spot, and improved HYLIFE-II BoP models as per Hoffman. Credits for improved plant availability and lower operating costs due to HYLIFE-II`s 30-yr target chamber lifetime are included, as well as unit cost reductions suggested by Delene to credit greater {open_quotes}learning curve{close_quotes} benefits for the duplicated portions of a multi-unit plant. To illustrate the potential impact of more advanced assumptions, additional {open_quotes}advanced{close_quotes} cases will consider the possible benefits of an MHD + Steam BoP, where direct MHD conversion of plasma from baseball-size LiH target blanket shells is assumed to be possible in a new (as yet undesigned) liquid Flibe-walled target chamber, together and separately, with advanced, higher-gain heavy-ion targets with Fast Ignitors. These runs may help decide the course of a possible future {open_quotes}HYLIFE-III{close_quotes} IFE study. Beam switchyard and final focusing system costs per target chamber are assumed to be consistent with single-sided illumination, for either {open_quotes}conventional{close_quotes} or {open_quotes}advanced{close_quotes} indirect target gain assumptions. Target costs are scaled according to the model by Woodworth. In all cases, the driver energy and rep rate for each chosen number of target chambers and total plant output will be optimized to minimize the cost of electricity (CoE) and the associated cost of hydrogen (CoH), using a relationship between CoE and CoH to be presented in the next section.

  9. Spin crossover behaviour in one-dimensional Fe(II) compounds based on the [M(CN)4](2-) (M = Pd, Pt) units. (United States)

    Zhang, Shao-Liang; Zhao, Xin-Hua; Wang, Yuan-Min; Shao, Dong; Wang, Xin-Yi


    Four one-dimensional heterobimetallic coordination polymers {Fe(pic)2[M(CN)4]}n (M = Pd(II) () and Pt(II) (), pic = 2-picolylamine), and {Fe(pypz)2[M(CN)4]}n (M = Pd(II) () and Pt(II) (), pypz = 2-(1H-pyrazol-3-yl)pyridine) have been synthesized and characterized by infrared spectroscopy, X-ray diffraction, magnetic measurements and differential scanning calorimetry (DSC). Single-crystal X-ray analyses show that all the compounds are 1D neutral zigzag chain structures in which the planar [M(CN)4](2-) anion acts as a μ2-bridging ligand, and the two pic/pypz molecules as chelating coligands. Examination of the intermolecular contacts in compounds reveals the existence of the hydrogen bonding interactions involving the hydrogen donor groups of the pic and pypz ligands and the nitrogen atoms of the non-bridging cyanide groups of the [M(CN)4](2-) anions. Weak π-π interactions were also found to be important for the formation of the 3D structures of compounds and . The SCO properties of all compounds were confirmed by the detailed structural analyses of the coordination environments of the Fe(II) centres, DSC analyses, and magnetic susceptibility measurements. Compounds and exhibit complete SCO behaviour with very narrow thermal hysteresis loops centred near the room temperature (T1/2↓ = 270 K and T1/2↑ = 272 K for and T1/2↓ = 272 K and T1/2↑ = 274 K for ), whereas and exhibit abrupt SCO at 186 and 180 K, respectively. Compared to the mononuclear species of the pic and pypz ligands, the SCO temperatures are adjusted by the different ligand field strength of the [M(CN)4)](2-) units. The cooperativity from both the coordination bonds and supramolecular interaction leads to the observation of the hysteresis loops in the Fe-pic systems and the abrupt SCO transition in the Fe-pypz systems. Furthermore, the light-induced excited-spin-state trapping (LIESST) effect was observed for .

  10. United States Responses to Japanese Wartime Inhuman Experimentation after World War II: National Security and Wartime Exigency (United States)

    Brody, Howard; Leonard, Sarah E.; Nie, Jing-Bao; Weindling, Paul


    In 1945-46, representatives of the United States government made similar discoveries in both Germany and Japan, unearthing evidence of unethical experiments on human beings that could be viewed as war crimes. The outcomes in the two defeated nations, however, were strikingly different. In Germany, the U.S., influenced by the Canadian physician John Thompson, played a key role in bringing Nazi physicians to trial and publicizing their misdeeds. In Japan, the U.S. played an equally key role in concealing information about the biological warfare experiments and securing immunity from prosecution for the perpetrators. The greater force of appeals to national security and wartime exigency help to explain these different outcomes. PMID:24534743

  11. Phase II Groundwater Flow Model of Corrective Action Unit 98: Frenchman Flat, Nevada Test Site, Nye County, Nevada, Rev. No.: 0

    Energy Technology Data Exchange (ETDEWEB)

    John McCord


    The Phase II Frenchman Flat groundwater flow model is a key element in the ''Federal Facility Agreement and Consent Order'' (FFACO) (1996) corrective action strategy for the Underground Test Area (UGTA) Frenchman Flat corrective action unit (CAU). The objective of this integrated process is to provide an estimate of the vertical and horizontal extent of contaminant migration for each CAU to predict contaminant boundaries. A contaminant boundary is the model-predicted perimeter that defines the extent of radionuclide-contaminated groundwater from underground testing above background conditions exceeding the ''Safe Drinking Water Act'' (SDWA) standards. The contaminant boundary will be composed of both a perimeter boundary and a lower hydrostratigraphic unit (HSU) boundary. The computer model will predict the location of this boundary within 1,000 years and must do so at a 95 percent level of confidence. Additional results showing contaminant concentrations and the location of the contaminant boundary at selected times will also be presented. These times may include the verification period, the end of the five-year proof-of-concept period, as well as other times that are of specific interest. This report documents the development and implementation of the groundwater flow model for the Frenchman Flat CAU. Specific objectives of the Phase II Frenchman Flat flow model are to: (1) Incorporate pertinent information and lessons learned from the Phase I Frenchman Flat CAU models. (2) Develop a three-dimensional (3-D), mathematical flow model that incorporates the important physical features of the flow system and honors CAU-specific data and information. (3) Simulate the steady-state groundwater flow system to determine the direction and magnitude of groundwater fluxes based on calibration to Frenchman Flat hydrogeologic data. (4) Quantify the uncertainty in the direction and magnitude of groundwater flow due to uncertainty in

    Full Text Available En este artículo se propone, a la luz de novedosos planteamientos teórico e historiográficos,This paper proposes a novel view of theoretical and historiographical approaches, as a first attempt, discussing the multicausal nature of contemporary international migration Mexico- United States. The intention is not going deeper into the different causal mechanisms, but only list them and ponder their interaction to better understand this phenomenon that goes beyond the macro-level considerations (economic and political. Migration, understood as a social process, manifests various causes and consequences in their past and present. And, in the case of the mass migration of Mexicans to the United States in recent decades, it is givable to think that this is a product of historical trends, economic asymmetries, of deep social inequalities and poverty in Mexico, of push and the pull factors, tradition and socialization migrant, social networks, transnational communities, symbolisms and collective imaginaries, modernization in transport and communication, migration industry, cultural values and psychological components, among others. It proposal is to analyze briefly this binational contemporary phenomenon under the epistemological consideration that migration is a social process. For this, macro, meso and microstructures will be essential in the explanation.

    None, None


    The C1ean Coal Technology (CCT) Program has been recognized in the National Energy Strategy as a major initiative whereby coal will be able to reach its full potential as a source of energy for the nation and the international marketplace. Attainment of this goal depends upon the development of highly efficient, environmentally sound, competitive coal utilization technologies responsive to diverse energy markets and varied consumer needs. The CCT Program is an effort jointly funded by government and industry whereby the most promising of the advanced coal-based technologies are being moved into the marketplace through demonstration. The CCT Program is being implemented through a total of five competitive solicitations. LIFAC North America, a joint venture partnership of ICF Kaiser Engineers, Inc., and Tampella Power Corporation, is currently demonstrating the LIFAC flue gas desulfurization technology developed by Tampella Power. This technology provides sulfur dioxide emission control for power plants, especially existing facilities with tight space limitations. Sulfur dioxide emissions are expected to be reduced by up to 85% by using limestone as a sorbent. The LIFAC technology is being demonstrated at Whitewater Valley Unit No. 2, a 60-MW coal-fired power plant owned and operated by Richmond Power and Light (RP&L) and located in Richmond, Indiana. The Whitewater plant consumes high-sulfur coals, with sulfur contents ranging from 2.0-2.9 $ZO. The project, co-funded by LIFAC North America and DOE, is being conducted with the participation of Richmond Power and Light, the State of Indiana, the Electric Power Research Institute (EPRI), and the Black Beauty Coal Company. The project has a total cost of $21.4 million and a duration of 48 months from the preliminary design phase through the testing program.

  19. Solvent-mediated secondary building units (SBUs) diversification in a series of MnII-based metal-organic frameworks (MOFs) (United States)

    Niu, Yan-Fei; Cui, Li-Ting; Han, Jie; Zhao, Xiao-Li


    The role of auxiliary solvents in the formation of MOFs has been investigated for a series of MnII-based framework systems. Reactions of 4,4‧,4″-nitrilotribenzoic acid (H3L) with MnII through varying auxiliary solvents of the medium resulted in the formation of diversified multinuclear MnII subunits in four new coordination polymers: [Mn3(L)(HCOO)3(DEF)3] (1), [Mn3(L)2(EtOH)2]·DMF (2), [Mn5(L)4(H2O)2]·2(H2NMe2)+·4DMF·2H2O (3), and [Mn3(L)2(py)4(H2O)]·H2O (4) (H3L=4,4‧,4‧-nitrilotribenzoic acid, DMF=dimethylformamide, DEF=N,N-diethylformamide, py=pyridine). These four compounds were fully characterized by single-crystal X-ray diffraction, showing interesting SBUs variations. For compound 1, it displays a (3,6)-connected kgd net with wheel [Mn6] cluster serving as SBU, whereas in 2, the sequence of Mn3(COO)9(EtOH)2 is repeated by inversion centers located between Mn1 and Mn3 to form an infinite Mn-carboxylate chain, which are further interlinked by L3- ligands to form a 3D architecture. In 3, the pentanuclear Mn5(CO2)12 clusters are interlinked to form a layer, which are further pillared by L3- to generate a 3D network. Compound 4 has a (3,6)-connected network in which the SBU is a linear trimeric Mn3(COO)6(py)4(H2O) cluster. In addition, the thermal stabilities, X-ray powder diffraction of all the compounds were studied, photoluminescence behaviors of compounds 1, 3 and 4 are discussed.

    Energy Technology Data Exchange (ETDEWEB)

    Greg Ruskauff


    The U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Site Office (NNSA/NSO) initiated the Underground Test Area (UGTA) Subproject to assess and evaluate radiologic groundwater contamination resulting from underground nuclear testing at the NTS. These activities are overseen by the Federal Facility Agreement and Consent Order (FFACO) (1996, as amended March 2010). For Frenchman Flat, the UGTA Subproject addresses media contaminated by the underground nuclear tests, which is limited to geologic formations within the saturated zone or 100 meters (m) or less above the water table. Transport in groundwater is judged to be the primary mechanism of migration for the subsurface contamination away from the Frenchman Flat underground nuclear tests. The intent of the UGTA Subproject is to assess the risk to the public from the groundwater contamination produced as a result of nuclear testing. The primary method used to assess this risk is the development of models of flow and contaminant transport to forecast the extent of potentially contaminated groundwater for the next 1,000 years, establish restrictions to groundwater usage, and implement a monitoring program to verify protectiveness. For the UGTA Subproject, contaminated groundwater is that which exceeds the radiological standards of the Safe Drinking Water Act (CFR, 2009) the State of Nevada’s groundwater quality standard to protect human health and the environment. Contaminant forecasts are expected to be uncertain, and groundwater monitoring will be used in combination with land-use control to build confidence in model results and reduce risk to the public. Modeling forecasts of contaminant transport will provide the basis for negotiating a compliance boundary for the Frenchman Flat Corrective Action Unit (CAU). This compliance boundary represents a regulatory-based distinction between groundwater contaminated or not contaminated by underground testing. Transport modeling simulations

  1. Mode of correction is related to treatment timing in Class II patients treated with the mandibular advancement locking unit (MALU) appliance. (United States)

    Candir, Muhsin; Kerosuo, Heidi


    To investigate the proportion of skeletal/dentoalveolar components for correction of Class II malocclusion in relation to the pubertal growth peak (PGP) among patients treated with the mandibular advancement locking unit (MALU) appliance. We conducted a retrospective study of 27 orthodontic patients (age range: 12-18 years; mean age 14.9 years) with skeletal Class II Division 1 malocclusion who were treated with the MALU appliance until they reached Class I occlusion with overjet and overbite within normal range. Pretreatment (T1) and posttreatment (T2) lateral cephalograms were analyzed using standard cephalometrics and sagittal occlusion analysis to assess changes in the dentoalveolar and skeletal complex. The cervical vertebral maturation (CVM) method was used to determine participants' skeletal maturation in T1 cephalograms. Based on this maturation, participants were divided into two groups: the peak group (treatment initiation before or during PGP [peak group, n=15]) or the postpeak group (treatment initiation after the PGP [n = 12]). No significant differences between groups were found at T1 for most of the skeletal and dental parameters investigated. At T2, the mean ANB angle and proclination of the mandibular incisors were significantly smaller in the peak group than in the postpeak group. In the peak group, skeletal correction comprised 54% and dental correction 46% of the total change at T2, while in the postpeak group the corresponding figures were 24% and 76%, respectively. Treatment initiated before or during PGP seems to result in a more favorable SNA/SNB relationship and less tipping of the mandibular incisors than when treatment is initiated after PGP.

  2. Evidence for single-chain magnet behavior in a Mn(III)-Ni(II) chain designed with high spin magnetic units: a route to high temperature metastable magnets. (United States)

    Clérac, Rodolphe; Miyasaka, Hitoshi; Yamashita, Masahiro; Coulon, Claude


    We herein present the synthesis, crystal structure, and magnetic properties of a new heterometallic chain of MnIII and NiII ions, [Mn2(saltmen)2Ni(pao)2(py)2](ClO4)2 (1) (saltmen2- = N,N'-(1,1,2,2-tetramethylethylene) bis(salicylideneiminate) and pao- = pyridine-2-aldoximate). The crystal structure of 1 was investigated by X-ray crystallographic analysis: compound 1 crystallized in monoclinic, space group C2/c (No. 15) with a = 21.140(3) A, b = 15.975(1) A, c = 18.6212(4) A, beta = 98.0586(4) degrees , V = 6226.5(7) A3, and Z = 4. This compound consists of two fragments, the out-of-plane dimer [Mn2(saltmen)2]2+ as a coordination acceptor building block and the neutral mononuclear unit [Ni(pao)2(py)2] as a coordination donor building block, forming an alternating chain having the repeating unit [-Mn-(O)2-Mn-ON-Ni-NO-]n. In the crystal structure, each chain is well separated with a minimum intermetallic distance between Mn and Ni ions of 10.39 A and with the absence of interchain pi overlaps between organic ligands. These features ensure a good magnetic isolation of the chains. The dc and ac magnetic measurements were performed on both the polycrystalline sample and the aligned single crystals of 1. Above 30 K, the magnetic susceptibility of this one-dimensional compound was successfully described in a mean field approximation as an assembly of trimers (Mn...Ni...Mn) with a NiII...MnIII antiferromagnetic interaction (J = -21 K) connected through a ferromagnetic MnIII...MnIII interaction (J'). However, the mean field theory fails to describe the magnetic behavior below 30 K emphasizing the one-dimensional magnetic character of the title compound. Between 5 and 15 K, the susceptibility in the chain direction was fitted to a one-dimensional Ising model leading to the same value of J'. Hysteresis loops are observed below 3.5 K, indicating a magnet-type behavior. In the same range of temperature, combined ac and dc measurements show a slow relaxation of the magnetization

    Electrooxidation of magnesium(II) porphine, a totally unsubstituted porphyrin, in acetonitrile solution under potentiostatic or potentiodynamic regime leads to a polymer film at the electrode surface. Polymer deposition takes place at extremely low potential, several hundred mV less positive even compared to the deposition potential for pyrrole or EDOT (at identical monomer concentrations) in the same solvent. Film thickness can be controlled by the passed deposition charge. This material and its THF-soluble fraction have been characterized by various electrochemical methods as well as by UV-visible and IR spectroscopies, XPS, XRD and MALDI-TOF techniques. This analysis has allowed us to conclude that the polymer film is composed by chains of Mg porphine building blocks, with single bonds between the neighboring units. In the course of the potential sweep, this polymer film demonstrates a redox response resembling that of polythiophene-coated electrodes. Namely, the film is electroactive and electronically conducting in two potential ranges (p- and n-doping), which are separated by a broad interval where the film possesses a much higher resistance. The polymer may be switched between all these redox states repeatedly by the change of the potential. The film capacitance in the electroactive potential intervals is proportional to the deposition charge.

  8. Corrective Action Decision Document/Corrective Action Plan for Corrective Action Unit 413: Clean Slate II Plutonium Dispersion (TTR) Tonopah Test Range, Nevada. Revision 0

    Energy Technology Data Exchange (ETDEWEB)

    Matthews, Patrick [Navarro, Las Vegas, NV (United States)


    This Corrective Action Decision Document/Corrective Action Plan provides the rationale and supporting information for the selection and implementation of corrective actions at Corrective Action Unit (CAU) 413, Clean Slate II Plutonium Dispersion (TTR). CAU 413 is located on the Tonopah Test Range and includes one corrective action site, TA-23-02CS. CAU 413 consists of the release of radionuclides to the surface and shallow subsurface from the Clean Slate II (CSII) storage–transportation test conducted on May 31, 1963. The CSII test was a non-nuclear detonation of a nuclear device located inside a concrete bunker covered with 2 feet of soil. To facilitate site investigation and the evaluation of data quality objectives decisions, the releases at CAU 413 were divided into seven study groups: 1 Undisturbed Areas 2 Disturbed Areas 3 Sedimentation Areas 4 Former Staging Area 5 Buried Debris 6 Potential Source Material 7 Soil Mounds Corrective action investigation (CAI) activities, as set forth in the CAU 413 Corrective Action Investigation Plan, were performed from June 2015 through May 2016. Radionuclides detected in samples collected during the CAI were used to estimate total effective dose using the Construction Worker exposure scenario. Corrective action was required for areas where total effective dose exceeded, or was assumed to exceed, the radiological final action level (FAL) of 25 millirem per year. The results of the CAI and the assumptions made in the data quality objectives resulted in the following conclusions: The FAL is exceeded in surface soil in SG1, Undisturbed Areas; The FAL is assumed to be exceeded in SG5, Buried Debris, where contaminated debris and soil were buried after the CSII test; The FAL is not exceeded at SG2, SG3, SG4, SG6, or SG7. Because the FAL is exceeded at CAU 413, corrective action is required and corrective action alternatives (CAAs) must be evaluated. For CAU 413, three CAAs were evaluated: no further action, clean closure, and

  9. Trypanosoma cruzi TcI and TcII transmission among wild carnivores, small mammals and dogs in a conservation unit and surrounding areas, Brazil. (United States)

    Aiming to better understand the ecological aspects of Trypanosoma cruzi transmission cycles, wild carnivores, small mammals and dogs were examined for T. cruzi infection in the Serra da Canastra National Park region, Brazil. Isolates were genotyped using mini-exon gene and PCR-RFLP (1f8 and H3) genomic targets. Trypanosoma cruzi transmission was well established in the area and occurred in both wild and peridomestic environments. Dog seroprevalence was 29·4% (63/214) and TcI and TcII genotypes, besides mixed infections were observed. Only TcI was detected in wild mammals. Marsupials displayed lower relative abundance, but a high prevalence of positive haemocultures (4/22), whereas rodents displayed positive haemocultures (9/113) mainly in the abundant Akodon montensis and Cerradomys subflavus species. The felid Leopardus pardalis was the only carnivore to display positive haemoculture and was captured in the same region where the small mammal prevalence of T. cruzi infection was high. Two canid species, Chrysocyon brachyurus and Cerdocyon thous, were serologically positive for T. cruzi infection (4/8 and 8/39, respectively), probably related to their capacity to exploit different ecological niches. Herein, dog infection not only signals T. cruzi transmission but also the genotypes present. Distinct transmission strategies of the T. cruzi genotypes are discussed.

  11. Air pollution and early deaths in the United States. Part II: Attribution of PM2.5 exposure to emissions species, time, location and sector (United States)

    Dedoussi, Irene C.; Barrett, Steven R. H.


    Combustion emissions constitute the largest source of anthropogenic emissions in the US, and lead to the degradation of air quality and human health. In Part I we computed the population fine particulate matter (PM2.5) exposure and number of early deaths caused by emissions from six major sectors: electric power generation, industry, commercial and residential activities, road transportation, marine transportation and rail transportation. In Part II we attribute exposure and early deaths to sectors, emissions species, time of emission, and location of emission. We apply a long-term adjoint sensitivity analysis and calculate the four dimensional sensitivities (time and space) of PM2.5 exposure with respect to each emissions species. Epidemiological evidence is used to relate increased population exposure to premature mortalities. This is the first regional application of the adjoint sensitivity analysis method to characterize long-term air pollution exposure. (A global scale application has been undertaken related to intercontinental pollution.) We find that for the electric power generation sector 75% of the attributable PM2.5 exposure is due to SO2 emissions, and 80% of the annual impacts are attributed to emissions from April to September. In the road transportation sector, 29% of PM2.5 exposure is due to NOx emissions and 33% is from ammonia (NH3), which is a result of emissions after-treatment technologies. We estimate that the benefit of reducing NH3 emissions from road transportation is ∼20 times that of NOx per unit mass. 75% of the road transportation ammonia impacts occur during the months October to March. We publicly release the sensitivity matrices computed, noting their potential use as a rapid air quality policy assessment tool.

    Zn(II)-phthalocyanines with tetra-substitution of D-galactose group on non-peripheral (nGalPc) and peripheral (pGalPc) positions have been studied as photodynamic sensitizers. The both complexes are water-soluble and highly aggregated in water and cell culture medium. The non-peripheral galactose units attached to the phthalocyanine macrocycle (nGalPc) lead to far red shift of absorbance maximum at 703 nm as compared to peripherally substituted pGalPc with maximum at 683 nm. The fluorescence maxima of the studied GalPcs were red shifted (8-14 nm) depending on the used solvent as compared to the absorption maxima. The relatively low fluorescence quantum yields in dimethylsulfoxide (0.06 for nGalPc and 0.21 for pGalPc) were determined. The singlet oxygen generation was determined with lower quantum yield for pGalPc (0.21) as compared to nGalPc (0.38). The lack of dark toxicity towards breast cancer cell line (MCF-7) in wide concentration range (0.125 - 10 μM) was observed. The uptake into the tumor cells and the subcellular localization in MCF-7 cells were determined with higher accumulation for pGalPc, compared to nGalPc. The in vitro photodynamic activity of GalPcs towards breast cancer cells was investigated for different dye concentrations and soft light parameters of 635 nm irradiation. The antitumor activity of nGalPc was superior to the pGalPc-induced cytotoxicity, due to higher generation of singlet oxygen and other reactive oxygen species.

  14. Corrective Action Investigation Plan for Corrective Action Unit 413: Clean Slate II Plutonium Dispersion (TTR) Tonopah Test Range, Nevada, Revision 1

    Energy Technology Data Exchange (ETDEWEB)

    Matthews, Patrick; Burmeister, Mark; Gallo, Patricia


    Corrective Action Unit (CAU) 413 is located on the Tonopah Test Range, which is approximately 130 miles northwest of Las Vegas, Nevada, and approximately 40 miles southeast of Tonopah, Nevada. The CAU 413 site consists of the release of radionuclides to the surface and shallow subsurface from the conduct of the Clean Slate II (CSII) storage–transportation test conducted on May 31, 1963. CAU 413 includes one corrective action site (CAS), TA-23-02CS (Pu Contaminated Soil). The known releases at CAU 413 are the result of the atmospheric deposition of contamination from the 1963 CSII test. The CSII test was a non-nuclear detonation of a nuclear device located inside a reinforced concrete bunker covered with 2 feet of soil. This test dispersed radionuclides, primarily plutonium, on the ground surface. The presence and nature of contamination at CAU 413 will be evaluated based on information collected from a corrective action investigation (CAI). The investigation is based on the data quality objectives (DQOs) developed on June 17, 2015, by representatives of the Nevada Division of Environmental Protection; the U.S. Air Force; and the U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Field Office. The DQO process was used to identify and define the type, amount, and quality of data needed to develop and evaluate appropriate corrective actions for CAU 413. The CAI will include radiological surveys, geophysical surveys, collection and analyses of soil samples, and assessment of investigation results. The collection of soil samples will be accomplished using both probabilistic and judgmental sampling approaches. To facilitate site investigation and the evaluation of DQO decisions, the releases at CAU 413 have been divided into seven study groups.

    Under new normal economy, the ten-year’s golden development in geological exploration industry has been ended, and the proifts have been decreased in a short time. However, in a midterm or long term, new normal economy will provide an opportunity for geological exploration industry to reform and build modern enterprise system. At the same time, downturn in the international mining market will offer good opportunities for Chinese enterprises abroad. Furthermore, traditional resource-based geology is changing its pattern; and green mining industry has become the new growth point. On this basis, this paper discusses that in order to grow and development stronger, geological exploration units should have a keen awareness of new normal and further enhance risk awareness, enhance efforts to top-level design and overall planning to promote the modernization of geological work. They should carry out cross-sectoral operation, put emphasis on the ifnancial world;accelerate scientiifc and technological innovation, and upgrade technical qualiifcations of workers and staff. Through hedging, they can enjoy the proift when the prices of mineral fall. In addition, they should set up a development fund, which can provide protection for major investment project for the fate of the units’ development;set up helping and rescue funds to solve the worries behind the unit staff.%经济新常态下,我国地勘行业结束了十年黄金发展期,短期效益下滑。从中长期来看,经济新常态为地勘行业改革、建立现代企业制度提供契机,国际矿业市场低迷为中国企业走出国门提供良机,传统资源型地质实施转型,绿色矿业成为新的增长点。地勘单位发展壮大,要认识新常态,进一步强化风险意识;加强顶层设计和总体规划,推进地质工作现代化;实行跨行业经营,重点突破金融领域;加快科技创新,提高职工技术素质;套期保值,在矿产品价格下跌

Successive alternation of the sheets and [Pd{CH(2)(PO(3))(2)}](3) units parallel to [001] produces the three-dimensional packing, which is also supported by a dense network of hydrogen bonds involving the solvent water molecules.

  19. Discussion in Postsecondary Classrooms

    Directory of Open Access Journals (Sweden)

    Curt Dudley-Marling


    Full Text Available Spoken language is, arguably, the primary means by which teachers teach and students learn. Much of the literature on language in classrooms has focused on discussion that is seen as both a method of instruction and a curricular outcome. While much of the research on discussion has focused on K-12 classrooms, there is also a body of research examining the efficacy of discussion in postsecondary settings. This article provides a review of this literature in order to consider the effect of discussion on student learning in college and university classrooms, the prevalence of discussion in postsecondary settings, and the quality of discussion in these settings. In general, the results of research on the efficacy of discussion in postsecondary settings are mixed. More seriously, researchers have not been explicit about the meaning of discussion and much of what is called discussion in this body of research is merely recitation with minimal levels of student participation. Although the research on discussion in college and university classrooms is inconclusive, some implications can be drawn from this review of the research including the need for future researchers to clearly define what they mean by “discussion.”

    Reactions of 2-(hydroxymethyl)pyridine (Hhmp) with PbCl2 and Pb(NO3)2 at room temperature led to the formation of two novel compounds, namely tetrakis[μ3-(pyridin-2-yl)methanolato]-tetrahedro-tetrakis[chloridolead(II)], [Pb4(C6H6NO)4Cl4], (I), and poly[(μ2-nitrato)[μ2-(pyridin-2-yl)methanolato]lead(II)], [Pb(C6H6NO)(NO3)]n, (II). Compound (I) exhibits a tetranuclear Pb4O4 cubane structure, which is connected through π-π stacking interactions between the pyridine groups of the (pyridin-2-yl)methanolate (hmp(-)) ligands and through C-H···Cl interactions to form an interesting threefold diamondoid network. Compound (II) possesses two-dimensional (4,4)-sql topology based on a Pb2O2 unit, which is further extended into a three-dimensional supramolecular network through π-π stacking interactions between adjacent pyridine rings and through C-H···O interactions between the pyridine C atoms of the hmp(-) ligands and the nitrate anions.

    Trypanosoma cruzi is classified into six discrete taxonomic units (DTUs). For this classification, different biological markers and classification criteria have been used. The objective was to identify the genetic profile of T. cruzi samples isolated from patients of two municipalities of Jequitinhonha Valley, MG, Brazil. Molecular characterization was performed using two different criteria for T. cruzi typing to characterize 63 T. cruzi samples isolated from chronic Chagas disease patients. The characterizations followed two distinct methodologies. Additionally, the RAPD technique was used to evaluate the existence of genetic intragroup variability. The first methodology identified 89% of the samples as TcII, but it was not possible to define the genetic identity of seven isolates. The results obtained with the second methodology corroborated the classification as TcII of the same samples and defined the classification of the other seven as TcVI. RAPD analysis showed lower intra-group variability in TcII. The results confirmed the preliminary data obtained in other municipalities of the Jequitinhonha Valley, showing a predominance of TcII, similar to that verified in northeast/south axis of Brazil and the first detection of TcVI in the study region. The second protocol was more simple and reliable to identify samples of hybrid character.

  16. Measuring energy expenditure in the intensive care unit: a comparison of indirect calorimetry by E-sCOVX and Quark RMR with Deltatrac II in mechanically ventilated critically ill patients. (United States)

    Rehal, Martin Sundström; Fiskaare, Erik; Tjäder, Inga; Norberg, Åke; Rooyackers, Olav; Wernerman, Jan


    Indirect calorimetry allows the determination of energy expenditure in critically ill patients by measuring oxygen consumption (VO2) and carbon dioxide production (VCO2). Recent studies have demonstrated variable performance of "breath-by-breath" instruments compared to mixing chamber technology. The aim of this study was to validate two modern devices (E-sCOVX and Quark RMR) against a reference method (Deltatrac II). Measurements of VO2/VCO2 with the test and reference devices were performed simultaneously over a 20-min period in mechanically ventilated adult intensive care unit patients. Accuracy and precision of instruments were analyzed using Bland-Altman plots. Forty-eight measurements in 22 patients were included for analysis. Both E-sCOVX and Quark RMR overestimated VO2 and VCO2 compared to Deltatrac II, corresponding to a 10% higher mean resting energy expenditure. Limits of agreement of resting energy expenditure within ± 2 standard deviations were ± 461 kcal/24 h (± 21% expressed as percentage error) for ΔE-sCOVX-Deltatrac II and ± 465 kcal/24 h (± 22%) for ΔQuark RMR-Deltatrac II. Both test devices overestimate VO2 and VCO2 compared to Deltatrac II. The observed limits of agreement are comparable to those commonly accepted in evaluations of circulatory monitoring, and significantly less than results from predictive equations. We hypothesize that the discrepancy between methods is due to patient/ventilator-related factors that affect the synchronization of gas and spirometry waveforms.

    Institute of Scientific and Technical Information of China (English)



    Internet banking has provide new ideas and ways for ensuring safe and efficient centralized management of funds in geological prospecting units. This means that through internet banking we have achieved bank-enterprise interconnection. By using internet technical operation, we have changed the traditional way of banking ifnancial services. By adopting the pattern of “tree group accounts”we have realized the centralized management. This paper goes on to look at that through internet banking the fund supervision that geological prospecting units performed to their branches has been enhanced. As a result, the efifciency of accounting work and the ifnancial management level have been increased, thus reducing the ifnancial costs. On this basis, this paper points out that in order to reduce the external risk of online banking, we must choose safe and reliable correspondent banks with mature technology. We must choose secure network and authentication medium so as to ensure a secured login. At the same time, a standard operational process and reasonable operation permission should be established so as to ensure the safe usage of online banking. In addition, strict internal accounting control system should be formulated so as to guard against online banking risk.%网上银行为确保地勘单位资金集中管理的安全高效提供了新思路和途径。通过网上银行实现了“银企互联”;利用Internet技术操作,改变了传统的银行金融服务方式;采用“树状集团开户”的模式,实现资金的集中管理。网上银行加强了地勘单位对各分支机构的资金监管、提高了会计工作效率和财务管理水平、降低了财务费用。选择安全可靠、技术成熟的代理银行,降低网上银行外部风险;选择安全的网络及认证介质,保证网上银行安全登录;建立规范的操作流程和合理的操作权限,保证网上银行安全使用;制定严密的内部会计控制制度

    Mullen, Lewis; Stamp, Robin C; Fox, Peter; Jones, Eric; Ngo, Chau; Sutcliffe, Christopher J


    In this study, the unit cell approach, which has previously been demonstrated as a method of manufacturing porous components suitable for use as orthopedic implants, has been further developed to include randomized structures. These random structures may aid the bone in-growth process because of their similarity in appearance to trabecular bone and are shown to carry legacy properties that can be related back to the original unit cell on which they are ultimately based. In addition to this, it has been shown that randomization improves the mechanical properties of regular unit cell structures, resulting in anticipated improvements to both implant functionality and longevity. The study also evaluates the effect that a post process sinter cycle has on the components, outlines the improved mechanical properties that are attainable, and also the changes in both the macro and microstructure that occur.

    Basel II replaces Basel I’s implicit capital charge on operational risk with an explicit charge. Certain U.S. banks concentrated in processing-related business lines – which have significant operational risk – could thus face an increase in overall minimum regulatory capital requirements. Some have argued that, as a result, these so-called “processing banks” would be disadvantaged vis-à-vis competitors not subject to regulatory capital requirements for operational risk.

The discussion was facilitated by the OAD and the conversation revolved mainly around two questions: (i) What should the OAD be doing to enhance the work of the Divisions? (ii) What could the Divisions (both members and respective scientific discipline in general) contribute towards the implementation of the IAU strategic plan?

  10. Buying time II: an economic evaluation of a joint NHS/Social Services residential rehabilitation unit for older people on discharge from hospital. (United States)

    Ellis, Annie; Trappes-Lomax, Tessa; Fox, Mary; Taylor, Rod; Power, Michael; Stead, Jonathan; Bainbridge, Ian


    The study's aim was to investigate the cost-effectiveness of an NHS/Social Services short-term residential rehabilitation unit (a form of intermediate care) for older people on discharge from community hospital compared with 'usual' community services. An economic evaluation was conducted alongside a prospective controlled trial, which explored the effectiveness of a rehabilitation unit in a practice setting. The aim of the unit was to help individuals regain independence. A matched control group went home from hospital with the health/social care services they would ordinarily receive. The research was conducted in two matched geographical areas in Devon: one with a rehabilitation unit, one without. Participants were recruited from January 1999 to October 2000 in 10 community hospitals and their eligibility determined using the unit's strict inclusion/exclusion criteria, including 55 years or older and likely to benefit from a short-term rehabilitation programme: potential to improve, realistic, achievable goals, motivation to participate. Ninety-four people were recruited to the intervention and 112 to the control group. Details were collated of the NHS and Social Services resources participants used over a 12-month follow-up. The cost of the resource use was compared between those who went to the unit and those who went straight home. Overall, costs were very similar between the two groups. Aggregated mean NHS/Social Services costs for the 12 months of follow-up were pound 8542.28 for the intervention group and pound 8510.68 for the control. However, there was a clear 'seesaw' effect between the NHS and Social Services: the cost of the unit option fell more heavily on Social Services (pound 5011.56, whereas pound 3530.72 to the NHS), the community option more so on the NHS (pound 5146.74, whereas pound 3363.94 to Social Services). This suggests that residential rehabilitation for older people is no more cost-effective over a year after discharge from community

    Data from National Health and Nutrition Examination Survey (NHANES) II (1976 to 1980), NHANES III (1988 to 1994), and NHANES 1999 to 2006 were examined to assess trends in total cholesterol (TC), low-density lipoprotein (LDL) cholesterol, high-density lipoprotein cholesterol, triglycerides (TGs), lipid-lowering medication use, and obesity. Age-adjusted decreases in TC (210 to 200 mg/dl) and LDL cholesterol (134 to 119 mg/dl) were observed. Those with high TC showed a decrease of 9% from NHANES II to NHANES 1999 to 2006, whereas those with LDL cholesterol ≥160 mg/dl showed a decrease of 8%. A significant increase in mean high-density lipoprotein cholesterol was observed (50 to 53 mg/dl, p lipid medication use by those with high cholesterol increased from 16% to 38%. Mean body mass index increased from 26 to 29 kg/m(2), and prevalence of obesity doubled and was significantly associated with increased TG. In conclusion, recent favorable trends in TC and LDL cholesterol are likely due to increased awareness of high cholesterol and the greater use of lipid-lowering drugs. However, countertrends in obesity and TG levels, if continued, will likely have a negative impact on cardiovascular disease in the future.

    Nazaryan, T A; Hakobyan, A A; McLean, B J; Kunth, D


    According to the database from the first paper, we select 180 pairs with dV < 800 km/s and Dp < 60 kpc containing Markarian (MRK) galaxies. We study the dependence of galaxies integral parameters, star-formation (SF) and active galactic nuclei (AGN) properties on kinematics of pairs, their structure and large-scale environments. Following main results were obtained: projected radial separation Dp between galaxies correlates with the perturbation level P of the pairs. Both parameters do not correlate with line-of-sight velocity difference dV of galaxies. Dp and P are better measures of interaction strength than dV. The latter correlates with the density of large-scale environment and with the morphologies of galaxies. Both galaxies in a pair are of the same nature, the only difference is that MRK galaxies are usually brighter than their neighbors in average by 0.9 mag. Specific star formation rates (SSFR) of galaxies in pairs with smaller Dp or dV is in average 0.5 dex higher than that of galaxies in pai...

  1. Empowerment: a conceptual discussion. (United States)

    Tengland, Per-Anders


    The concept of 'empowerment' is used frequently in a number of professional areas, from psychotherapy to social work. But even if the same term is used, it is not always clear if the concept denotes the same goals or the same practice in these various fields. The purpose of this paper is to clarify the discussion and to find a plausible and useful definition of the concept that is suitable for work in various professions. Several suggestions are discussed in the paper, for example control over life or health, autonomy, ability, self-efficacy, self-esteem, and freedom, and it is concluded that there are two plausible complementary uses, one as a goal and one as a process or approach. Empowerment as a goal is to have control over the determinants of one's quality of life, and empowerment as a process is to create a professional relation where the client or community takes control over the change process, determining both the goals of this process and the means to use.

    Provost, Hervé Le; Flouzat, Christophe; Kestener, Pierre; Chaminade, Thomas; Donati, Modeste; Château, Frédéric; Daly, François; Fontignie, Jean


    The Scientific Trigger Unit (UTS) is a satellite equipment designed to detect Gamma Ray Bursts (GRBs) observed by the onboard 6400 pixels camera ECLAIRs. It is foreseen to equip the low-Earth orbit French-Chinese satellite SVOM and acts as the GRB trigger unit for the mission. The UTS analyses in real-time and in great details the onboard camera data in order to select the GRBs, to trigger a spacecraft slew re-centering each GRB for the narrow field-of-view instruments, and to alert the ground telescope network for GRB follow-up observations. A few GRBs per week are expected to be observed by the camera; the UTS targets a close to 100% trigger efficiency, while being selective enough to avoid fake alerts. This is achieved by running the complex scientific algorithms on a radiation tolerant hardware, based on a FPGA data pre-processor and a CPU with a Real-Time Operating System. The UTS is a scientific software, firmware and hardware co-development. A Data Processing Model (DPM) has been developed to fully val...

  8. Contaminants in stream sediments from seven United States metropolitan areas: part II--sediment toxicity to the amphipod Hyalella azteca and the midge Chironomus dilutus. (United States)

    Kemble, Nile E; Hardesty, Douglas K; Ingersoll, Christopher G; Kunz, James L; Sibley, Paul K; Calhoun, Daniel L; Gilliom, Robert J; Kuivila, Kathryn M; Nowell, Lisa H; Moran, Patrick W


    Relationships between sediment toxicity and sediment chemistry were evaluated for 98 samples collected from seven metropolitan study areas across the United States. Sediment-toxicity tests were conducted with the amphipod Hyalella azteca (28 day exposures) and with the midge Chironomus dilutus (10 day exposures). Overall, 33 % of the samples were toxic to amphipods and 12 % of the samples were toxic to midge based on comparisons with reference conditions within each study area. Significant correlations were observed between toxicity end points and sediment concentrations of trace elements, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), or organochlorine (OC) pesticides; however, these correlations were typically weak, and contaminant concentrations were usually below sediment-toxicity thresholds. Concentrations of the pyrethroid bifenthrin exceeded an estimated threshold of 0.49 ng/g (at 1 % total organic carbon) in 14 % of the samples. Of the samples that exceeded this bifenthrin toxicity threshold, 79 % were toxic to amphipods compared with 25 % toxicity for the samples below this threshold. Application of mean probable effect concentration quotients (PECQs) based on measures of groups of contaminants (trace elements, total PAHs, total PCBs, OC pesticides, and pyrethroid pesticides [bifenthrin in particular]) improved the correct classification of samples as toxic or not toxic to amphipods compared with measures of individual groups of contaminants.

    Fineman, C.P.


    In the past, safety and relief valves installed in the primary coolant system of light water reactors have performed improperly. As a result, the authors of NUREG-0578 (TMI-2 Lessons Learned Task Force Status Report and Short-Term Recommendations) and, subsequently, NUREG-0737 (Clarification of TMI Action Plan Requirements) recommended development and completion of programs to do two things. First, the programs should reevaluate the functional performance capabilities of pressurized water reactor safety, relief, and block valves. Second, they should verify the integrity of the pressurizer safety and relief valve piping systems for normal, transient, and accident conditions. This report documents the review of those programs by EG&G Idaho, Inc. Specifically, this report documents the review of the Comanche Peak, Unit 2, Applicant response to the requirements of NUREG-0578 and NUREG-0737. This review found the Applicant provided an acceptable response reconfirming they met General Design Criteria 14, 15, and 30 of Appendix A to 10 CFR 50 for the subject equipment.

  10. Solvent-induced secondary building unit (SBU) variations in a series of Cu(II) metal-organic frameworks derived from a bifunctional ligand. (United States)

    Chen, Di-Ming; Ma, Jian-Gong; Cheng, Peng


    The role of auxiliary solvents in the formation of metal-organic frameworks (MOFs) has been studied for a series of copper-based framework systems. Herein we show the formation of three different 3D ordered frameworks with the formulae {[Cu4(cpt)4Cl4]·2DMF·dioxane·3H2O}n (1), {[Cu8(cpt)4(Hcpt)2Cl7(μ3-OH)2(H2O)4]Cl3·4CH3CN}n (2), and {[Cu8(cpt)4Cl4(μ3-OH)2(μ4-O)2]Cl2·4H2O·2CH3CN·3MeOH}n (3) [Hcpt = 4-(4-carboxyphenyl)-1,2,4-triazole], respectively, from the same reaction mixture through varying auxiliary solvents of the medium. These MOFs were fully characterized by single-crystal X-ray diffraction, showing interesting secondary building unit (SBU) variations. The varied SBUs not only bring different framework architectures to these MOFs, but also affect their framework stability. Gas sorption studies of MOF 3 reveal high CO2-N2 selectivity at 298 K and 0.16 bar (a typical partial pressure of CO2 in an industrial flue gas). A high isosteric heat of adsorption (Qst) at zero loading (53 kJ mol(-1)) was also observed in MOF 3.

  11. The issue of penal and legal protection of the intensive care unit physician within the context of patient's consent to treatment. Part II: unconscious patient. (United States)

    Siewiera, Jacek; Kübler, Andrzej; Filipowska, Monika; Trnka, Jakub; Zamaro-Michalska, Aleksandra


    Cultural changes in Western societies, as well as the rapid development of medical technology during the last quarter of a century, have led to many changes in the relationship between a physician and a patient. During this period, the patient's consent to treatment has proven to be an essential component of any decision relating to the patient's health. The patient's will component, as an essential element of the legality of the treatment process, is also reflected in the Polish legislation. The correct interpretation of the legal regulations and the role the patient's will plays in the therapeutic decision-making process within the Intensive Care Unit (ICU) requires the consideration of both the good of the patient and the physician's safety in terms of his criminal responsibility. Clinical experience indicates that the physicians' decisions result in the choice of the best treatment strategy for a patient only if they are based on current medical knowledge and an assessment of therapeutic opportunities. The good of the patient must be the sole objective of the physician's actions, and as a result of the current state of medical knowledge and the medical prognosis, all the conditions of the legal safety of a physician taking decisions must be met. In this paper, the authors have set out how to obtain consent (substantive consent) to treat an unconscious patient in the ICU in light of the current Polish law, as well as a physician's daily practice. The solutions proposed in the text of the publication are aimed at increasing the legal safety of the ICU physicians when making key decisions relating to the strategy of the treatment of ICU patients.

    The synthesis, magnetic characterization and X-ray crystal structures are reported for five new manganese compounds, [Mn(III)(teaH(2))(sal)]·(1/2)H(2)O (1), [Na(I)(2)Mn(II)(4)Mn(III)(4)(teaH)(6)(sal)(4)(N(3))(2)(MeOH)(4)]·6MeOH (2), [Na(I)(2)Mn(II)(4)Mn(III)(4)(teaH)(6)(sal)(4)(N(3))(2)(MeOH)(2)](n)·7MeOH (3), [Na(I)(2)Mn(II)(4)Mn(III)(4)(teaH)(6)(sal)(4)(N(3))(2)(MeOH)(2)](n)·2MeOH·Et(2)O (4) and [K(I)(2)Mn(II)(4)Mn(III)(4)(teaH)(6)(sal)(4)(N(3))(2)(H(2)O)(2)](n)·5MeOH (5). Complex 1 is a mononuclear compound, formed via the reaction of Mn(NO(3))(2)·4H(2)O, triethanolamine (teaH(3)) and salicylic acid (salH(2)) in a basic methanolic solution. Compound 2 is a mixed-valent hetero-metallic cluster made up of a Mn(8)Na(2) decanuclear core and is formed via the reaction of sodium azide (NaN(3)) with 1. Compounds 3-5 are isolated as 1- or 2-D coordination polymers, each containing the decanuclear Mn(8)M(2) (M = Na(+) or K(+)) core building block as the repeating unit. Compound 3 is isolated when 1 is reacted with NaN(3) over a very short reaction time and forms a 1-D coordination polymer. Each unit displays inter-cluster bridges via the O-atoms of teaH(2-) ligands bonding to the sodium ions of an adjacent cluster. Increasing the reaction time appears to drive the formation of 4 which forms 2-D polymeric sheets and is a packing polymorph of 3. The addition of KMnO(4) and NaN(3) to 1 resulted in compound 5, which also forms a 1-D coordination polymer of the decanuclear core unit. The 1-D chains are now linked via inter-cluster potassium and salicylate bridges. Solid state DC susceptibility measurements were performed on compounds 1-5. The data for 1 are as expected for an S = 2 Mn(III) ion, with the isothermal M vs. H data being fitted by matrix diagonalization methods to give values of g and the axial (D) and rhombic (E) zero field splitting parameters of 2.02, -2.70 cm(-1) and 0.36 cm(-1) respectively.

    To Japan who was stopped exercising a state sovereignty after being defeated, realizing peace-making, ending the occupation as soon as possible, resuming the exercise of sovereignty and rejoining the international community were the most important diplomatic topics in the early days of postwar. In this process, how to minimize the cost, use the most advantageous way to make peace had become the concern of all sectors of the Japanese society. However, when to make peace and what were put in the peace treaty depended on countries winning the war. After World War II, US-Soviet Union contradiction became inten-sified, and the dark clouds of the Cold War spread in East Asia; the USA who had the dominant right over the occupation of Japan, in order to make Japan an”East Asia breakwater against the Communist”, singed a ”lenient peacemaking” over Japan, increasing the opportunities that Japan could join the discussion of peacemaking abruptly. Under the situation of a rapid spreading of the Cold War, security issues associated with the disposal problems of surrounding islands of Japan became the key to making peace with the allies. Finally, Shigeru Yoshida government accepted the continuation of deployment of U.S army and agreed U.S to trust Okinawa in the name of the United Nations by sacrificing the interests of the people in Okinawa, and in the way of retaining the potential sovereignty (or ’residual sovereignty’), and limited restoration of sovereignty to realize the peacemaking with the majority of western camp, that is, a de facto”one-sided peacemaking”.%  对战败以后被停止行使国家主权的日本来说,尽快实现媾和结束占领,恢复行使国家主权,重返国际社会是战后初期最重要的外交课题。在这一过程中,如何以最小的代价,以对己最有利的方式实现媾和成为日本各界关注的焦点。然而,一般来说何时媾和,把何种问题纳入媾和议题等均由掌握媾和主

  14. A comparative analysis of predictive models of morbidity in intensive care unit after cardiac surgery – Part II: an illustrative example

    Directory of Open Access Journals (Sweden)

    Giomarelli Pierpaolo


    Full Text Available Abstract Background Popular predictive models for estimating morbidity probability after heart surgery are compared critically in a unitary framework. The study is divided into two parts. In the first part modelling techniques and intrinsic strengths and weaknesses of different approaches were discussed from a theoretical point of view. In this second part the performances of the same models are evaluated in an illustrative example. Methods Eight models were developed: Bayes linear and quadratic models, k-nearest neighbour model, logistic regression model, Higgins and direct scoring systems and two feed-forward artificial neural networks with one and two layers. Cardiovascular, respiratory, neurological, renal, infectious and hemorrhagic complications were defined as morbidity. Training and testing sets each of 545 cases were used. The optimal set of predictors was chosen among a collection of 78 preoperative, intraoperative and postoperative variables by a stepwise procedure. Discrimination and calibration were evaluated by the area under the receiver operating characteristic curve and Hosmer-Lemeshow goodness-of-fit test, respectively. Results Scoring systems and the logistic regression model required the largest set of predictors, while Bayesian and k-nearest neighbour models were much more parsimonious. In testing data, all models showed acceptable discrimination capacities, however the Bayes quadratic model, using only three predictors, provided the best performance. All models showed satisfactory generalization ability: again the Bayes quadratic model exhibited the best generalization, while artificial neural networks and scoring systems gave the worst results. Finally, poor calibration was obtained when using scoring systems, k-nearest neighbour model and artificial neural networks, while Bayes (after recalibration and logistic regression models gave adequate results. Conclusion Although all the predictive models showed acceptable

    Gross, Franz; Epelbaum, Evgeny; Machleidt, Ruprecht


    Discussion of the nuclear force, lead by a round table consisting of T. Cohen, E. Epelbaum, R. Machleidt, and F. Gross (chair). After an invited talk by Machleidt, published elsewhere in these proceedings, brief remarks are made by Epelbaum, Cohen, and Gross, followed by discussion from the floor moderated by the chair. The chair asked the round table and the participants to focus on the following issues: (i) What does each approach (chiral effective field theory, large Nc, and relativistic phenomenology) contribute to our knowledge of the nuclear force? Do we need them all? Is any one transcendent? (ii) How important for applications (few body, nuclear structure, EMC effect, for example) are precise fits to the NN data below 350 MeV? How precise do these fits have to be? (iii) Can we learn anything about nonperturbative QCD from these studies of the nuclear force? The discussion presented here is based on a video recording made at the conference and transcribed afterward.

  20. PIP-II Transfer Line Design

    Energy Technology Data Exchange (ETDEWEB)

    Vivoli, A. [Fermilab


    The U.S. Particle Physics Project Prioritization Panel (P5) report encouraged the realization of Fermilab's Proton Improvement Plan II (PIP-II) to support future neutrino programs in the United States. PIP-II aims at enhancing the capabilities of the Fermilab existing accelerator complex while simultaneously providing a flexible platform for its future upgrades. The central part of PIP-II project is the construction of a new 800 MeV H- Superconducting (SC) Linac together with upgrades of the Booster and Main Injector synchrotrons. New transfer lines will also be needed to deliver beam to the down-stream accelerators and facilities. In this paper we present the recent development of the design of the transfer lines discussing the principles that guided their design, the constraints and requirements imposed by the existing accelerator complex and the following modifications implemented to comply with a better understanding of the limitations and further requirements that emerged during the development of the project.

  1. Dietary intake estimates as a means to the harmonization of maximum residue levels for veterinary drugs. II. Proposed application to the Free Trade Agreement between the United States and Canada. (United States)

    Fitzpatrick, S C; Vilim, A; Lambert, G; Yong, M S; Brynes, S D


    The Free Trade Agreement between the United States and Canada (FTA) went into effect January 1, 1989. To implement certain provisions of the agreement on technical regulations and standards, the United States Food and Drug Administration's Center for Veterinary Medicine, Health and Welfare Canada's Bureau of Veterinary Drugs, and Agriculture Canada established the Working Group on Veterinary Drug Tolerances. The progress of the working group and its continuing efforts to harmonize tolerances for approximately 15 veterinary drugs are discussed. This paper proposes use of the toxicologically determined acceptable daily intake (ADI) for the drug as the safety standard for reaching conclusions on the acceptability of residues in meat for human consumption. Specifically, the "equivalence" of different MRLs for the same veterinary drug would be determined by considering whether they are likely to result in dietary residues that exceed the other country's ADI for the drug. Estimates are made for the veterinary drugs lasalocid, fenbendazole, morantel tartrate, halofuginone, and tilmicosin. Based on these estimates, the U.S. and Canadian MRLs for each drug would be considered equivalent for trade purposes.

  3. Dimensionless Units in the SI

    CERN Document Server

    Mohr, Peter J


    The International System of Units (SI) is supposed to be coherent. That is, when a combination of units is replaced by an equivalent unit, there is no additional numerical factor. Here we consider dimensionless units as defined in the SI, {\\it e.g.} angular units like radians or steradians and counting units like radioactive decays or molecules. We show that an incoherence may arise when different units of this type are replaced by a single dimensionless unit, the unit "one", and suggest how to properly include such units into the SI in order to remove the incoherence. In particular, we argue that the radian is the appropriate coherent unit for angles and that hertz is not a coherent unit in the SI. We also discuss how including angular and counting units affects the fundamental constants.

    Stephen Bernow


    Full Text Available This paper presents and discusses an integrated set of policies designed to reduce U.S. carbon emissions over the next four decades. This innovation path also aims to promote environmental quality, particularly by reducing emissions of criteria air pollutants, to reduce U.S. dependence on imported oil, and to induce technological innovation and diffusion in energy production and consumption. The innovation path would reduce economy-wide carbon emissions by 26% below baseline projections for 2010 and by 62% below baseline projections for 2030; this translates into 10% below 1990 levels in 2010 and 45% below 1990 levels in 2030. Emissions of criteria pollutants also would be significantly reduced, as would petroleum imports by the United States. Moreover, the innovation path would yield cumulative net savings for the United States of $218 billion (1993 dollars through 2010, or $19 billion on a leveled annual basis, and would result in 800,000 additional jobs nationwide by 2010. Although the overall findings from the innovation path analysis are robust, the results should be taken as indicative, rather than precisely predictive, owing to uncertainties in future costs, prices, technology performance, and consumer behavior.

  8. Conversational Markers of Constructive Discussions

    CERN Document Server

    Niculae, Vlad


    Group discussions are essential for organizing every aspect of modern life, from faculty meetings to senate debates, from grant review panels to papal conclaves. While costly in terms of time and organization effort, group discussions are commonly seen as a way of reaching better decisions compared to solutions that do not require coordination between the individuals (e.g. voting)---through discussion, the sum becomes greater than the parts. However, this assumption is not irrefutable: anecdotal evidence of wasteful discussions abounds, and in our own experiments we find that over 30% of discussions are unproductive. We propose a framework for analyzing conversational dynamics in order to determine whether a given task-oriented discussion is worth having or not. We exploit conversational patterns reflecting the flow of ideas and the balance between the participants, as well as their linguistic choices. We apply this framework to conversations naturally occurring in an online collaborative world exploration ga...

  9. Fractional distillation as a strategy for reducing the genotoxic potential of SRC-II coal liquids: a status report

    Energy Technology Data Exchange (ETDEWEB)

    Pelroy, R.A.; Wilson, B.W.


    This report presents results of studies on the effects of fractional distillation on the genotoxic potential of Solvent Refined Coal (SRC-II) liquids. SRC-II source materials and distilled liquids were provided by Pittsburg and Midway Coal Mining Co. Fractional distillations were conducted on products from the P-99 process development unit operating under conditions approximating those anticipated at the SRC-II demonstration facility. Distillation cuts were subjected to chemical fractionation, in vitro bioassay and initial chemical analysis. Findings are discussed as they relate to the temperature at which various distillate cuts were produced. This document is the first of two status reports scheduled for 1981 describing these studies.

  13. Small group discussion: Students perspectives. (United States)

    Annamalai, Nachal; Manivel, Rajajeyakumar; Palanisamy, Rajendran


    Various alternative methods are being used in many medical colleges to reinforce didactic lectures in physiology. Small group teaching can take on a variety of different tasks such as problem-solving, role play, discussions, brainstorming, and debate. Research has demonstrated that group discussion promotes greater synthesis and retention of materials. The aims of this study were to adopt a problem-solving approach by relating basic sciences with the clinical scenario through self-learning. To develop soft skills, to understand principles of group dynamics, and adopt a new teaching learning methodology. Experimental study design was conducted in Phase I 1(st) year medical students of 2014-2015 batch (n = 120). On the day of the session, the students were grouped into small groups (15 each). The session started with the facilitator starting off the discussion. Feedback forms from five students in each group was taken (n = 40). A five point Likert scale was used ranging from strongly agree to strongly disagree. Data were analyzed using IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp. Our results show that 70% of the students opined that small group discussion were interactive, friendly, innovative, built interaction between teacher and student. Small group discussion increased their thought process and helped them in better communication. The small group discussion was interactive, friendly, and bridged the gap between the teacher and student. The student's communication skills are also improved. In conclusion, small group discussion is more effective than the traditional teaching methods.

  16. Socrates, discussion and moral education (United States)

    Rembert, Ron B.


    For Socrates, as he appears in Plato's dialogues, the process of discussion is essential for preparing human beings to lead a moral life. Only through discussion, Socrates maintains, can we be led to an understanding of such concepts as wisdom, courage and justice. The author of this article believes that the Socratic notion of the moral value of discussion is still valid. In support of this view, he examines two recent works: Dialogues on Moral Education by John Wilson and Barbara Cowell, and Moral Education, Secular and Religious by John L. Elias. Finally, the author suggests how the Socratic concept of dialogue might be used in moral education today.

  1. Mod II engine performance (United States)

    Richey, Albert E.; Huang, Shyan-Cherng


    The testing of a prototype of an automotive Stirling engine, the Mod II, is discussed. The Mod II is a one-piece cast block with a V-4 single-crankshaft configuration and an annular regenerator/cooler design. The initial testing of Mod II concentrated on the basic engine, with auxiliaries driven by power sources external to the engine. The performance of the engine was tested at 720 C set temperature and 820 C tube temperature. At 720 C, it is observed that the power deficiency is speed dependent and linear, with a weak pressure dependency, and at 820 C, the power deficiency is speed and pressure dependent. The effects of buoyancy and nozzle spray pattern on the heater temperature spread are investigated. The characterization of the oil pump and the operating cycle and temperature spread tests are proposed for further evaluation of the engine.

  3. Interaction in online interprofessional education case discussions. (United States)

    Waterston, Rosemary


    This study investigated online interaction within a curriculum unit at the University of Toronto, Canada that included an interprofessional case study discussion in a mixed-mode (face-to-face and online) format. Nine of the 81 teams that completed the four-day curriculum were selected for detailed review based on the attitudes students expressed on a survey about the value of collaborating online for enhancing their appreciation of other health care professions. Five of the teams selected were 'positive' and four were 'negative'. The responses to other survey items by members of these teams were then compared, as well as their message posting patterns and the content of their online discussions. Differences between the two sets were situated within a theoretical framework drawn from the contact theory, social interdependence theory, and the Community of Inquiry model. Institutional support in the form of facilitator involvement, individual predispositions to online and group learning, the group composition, the learning materials, task and assignment, and technical factors all affected the levels of participation online. Discourse and organizational techniques were identified that related to interactivity within the online discussions. These findings can help curriculum planners design interprofessional case studies that encourage the interactivity required for successful online discussions.

  7. National Academy of Neuropsychology/Division 40 of the American Psychological Association Practice Survey of Clinical Neuropsychology in the United States. Part II: Reimbursement experiences, practice economics, billing practices, and incomes. (United States)

    Sweet, Jerry J; Peck, Edward A; Abramowitz, Carolyn; Etzweiler, Sharon


    Leaders of the National Academy of Neuropsychology and Division 40 (Clinical Neuropsychology) of the American Psychological Association determined that current information on the professional practice of clinical neuropsychology within the United States was needed. These two organizations co-sponsored a national survey of U.S. clinical neuropsychologists that was conducted in September 2000. The primary goal of the survey was to gather information on such topics as: practitioner and practice characteristics, economic variables (e.g., experience with major third party payors, such as Medicare and managed care), practice expenses, billing methods, experiences with Current Procedural Terminology (CPT) codes, time spent on various clinical tasks, use of assistants, and income. In this second of two articles describing the survey results, reimbursement experiences, practice economics, billing practices, and incomes are highlighted. Survey results indicate that neuropsychologists frequently have difficulty gaining access to membership on managed care panels. For those who gain access, managed care companies often limit provision of services; this is quite often perceived as negatively affecting quality of patient care. It is very common for neuropsychologists to feel obligated to provide more services to managed care and Medicare patients than are allowed to be billed to the insurance carrier; these hours are typically "written off." Numerous CPT codes are used to bill the same clinical service. Awareness of Medicare practice and billing expectations is variable among practitioners, as is awareness of public aid/Medicaid billing status. Professional income is influenced by years of licensed practice, practice setting, gender, types and amounts of non-clinical professional activities, and types and amounts of reimbursement sources within one's clinical practice. Income of neuropsychologists has only a minimal relationship to percentage of clinical practice per week

    Juodkazyte, Jurga; Sebeka, Benjaminas; Savickaja, Irena; Malinauskas, Tadas; Badokas, Kazimieras; Juodkazis, Kestutis; Juodkazis, Saulius


    The current state of the art in direct water splitting in photo-electrochemical cells (PECs) is presented together with: (i) a case study of water splitting using a simple solar cell with the most efficient water splitting electrodes and (ii) a detailed mechanism analysis. Detailed analysis of the energy balance and efficiency of solar hydrogen production are presented. The role of hydrogen peroxide formation as an intermediate in oxygen evolution reaction is newly revealed and explains why an oxygen evolution is not taking place at the thermodynamically expected 1.23 V potential. Solar hydrogen production with electrical-to-hydrogen conversion efficiency of 52% is demonstrated using a simple ~0.7%-efficient n-Si/Ni Schottky solar cell connected to a water electrolysis cell. This case study shows that separation of the processes of solar harvesting and electrolysis avoids photo-electrode corrosion and utilizes optimal electrodes for hydrogen and oxygen evolution reactions and achieves ~10% efficiency in light...

  18. RADTRAN II user guide

    Energy Technology Data Exchange (ETDEWEB)

    Madsen, M M; Wilmot, E L; Taylor, J M


    RADTRAN II is a flexible analytical tool for calculating both the incident-free and accident impacts of transporting radioactive materials. The consequences from incident-free shipments are apportioned among eight population subgroups and can be calculated for several transport modes. The radiological accident risk (probability times consequence summed over all postulated accidents) is calculated in terms of early fatalities, early morbidities, latent cancer fatalities, genetic effects, and economic impacts. Groundshine, inhalation, direct exposure, resuspension, and cloudshine dose pathways are modeled to calculate the radiological health risks from accidents. Economic impacts are evaluated based on costs for emergency response, cleanup, evacuation, income loss, and land use. RADTRAN II can be applied to specific scenario evaluations (individual transport modes or specified combinations), to compare alternative modes or to evaluate generic radioactive material shipments. Unit-risk factors can easily be evaluated to aid in performing generic analyses when several options must be compared with the amount of travel as the only variable.

We tested whether this group advantage extends to lie detection, an exceptionally challenging judgment with accuracy rates rarely exceeding chance. In four experiments, we find that groups are consistently more accurate than individuals in distinguishing truths from lies, an effect that comes primarily from an increased ability to correctly identify when a person is lying. These experiments demonstrate that the group advantage in lie detection comes through the process of group discussion, and is not a product of aggregating individual opinions (a "wisdom-of-crowds" effect) or of altering response biases (such as reducing the "truth bias"). Interventions to improve lie detection typically focus on improving individual judgment, a costly and generally ineffective endeavor. Our findings suggest a cheap and simple synergistic approach of enabling group discussion before rendering a judgment.

  1. Discussion boards: boring no more! (United States)

    Adelman, Deborah S; Nogueras, Debra J


    Creating discussion boards (DBs) that capture student imaginations and contain meaningful interactions can be a difficult process. Traditional DBs use a question-and-answer format that often is boring for both the student and instructor. The authors present creative approaches to DBs that result in lively debates and student-to-student and student-to-faculty interactions, including role playing, blogging, wikis, and the use of voice.

  3. Discussions on Hypnosis and Schizophrenia. (United States)

    Haley, Jay


    A classic paper in intellect and argument, this article contains a transcript of a conversation between Jay Haley, John Weakland, and Milton Erickson as they discuss the role of communication in hypnosis and schizophrenia. In 1955, schizophrenia was considered primarily a psychological disorder. Whereas today schizophrenia is mostly considered a biological disorder, this very early, unpublished paper still gives much food for thought and a further glimpse into Haley and Erickson's thinking and intellect at a fervent time in schizophrenia research.

  4. Predicting outcome in the intensive care unit using scoring systems: is new better? A comparison of SAPS and SAPS II in a cohort of 1,393 patients. GiViTi Investigators (Gruppo Italiano per la Valutazione degli interventi in Terapia Intensiva). Simplified Acute Physiology Score. (United States)

    Bertolini, G; D'Amico, R; Apolone, G; Cattaneo, A; Ravizza, A; Iapichino, G; Brazzi, L; Melotti, R M


    This study sought to compare the performance of the old and new versions of the Simplified Acute Physiology Score, SAPS and SAPS II, in classifying patients according to the risk of hospital mortality. To compare the performance of the two systems, measures of association between the scores and observed mortality were adopted, together with discrimination (area under the Receiver Operating Characteristics curve) and calibration (goodness-of-fit statistics) estimates. Subjects were 1,393 eligible patients recruited during 1 month in 1994. The outcome measure was vital status at hospital discharge. SAPS II was associated more strongly with hospital mortality than the earlier version. SAPS II also had better discrimination ability than SAPS (area under Receiver Operating Characteristics curve 0.80 versus 0.74) and predicted an overall number of deaths (416.5) closer to the observed figure (475) than SAPS (267.7). Conversely, neither SAPS nor SAPS II fitted our data. Both P values derived from goodness-of-fit statistics were lower than 0.05. SAPS II offers a real improvement compared with SAPS in its ability to explain hospital mortality, but its standard parameters do not fit our data from Italy. The role and impact of potential determinants of this lack of fit, such as random errors and confounders related to casemix and/or quality of care should be clarified before this scoring system be used outside formal research projects. Special caution is suggested when SAPS II is adopted to predict mortality to compare intensive care unit performance across different countries and systems of care.

  7. Some discussions on Arctic vortex

    Institute of Scientific and Technical Information of China (English)

    Li Hai; Sun Lantao; Wu Huiding; Li Xiang


    The Arctic vortex is a persistent large-scale cyclonic circulation in the middle and upper troposphere and the stratosphere. Its activity and variation control the semi-permanent active centers of Pan-Arctic and the short-time cyclone activity in the subarctic areas. Its strength variation, which directly relates to the atmosphere, ocean, sea ice and ecosystem of the Arctic, can affect the lower atmospheric circulation, the weather of subarctic area and even the weather of middle latitude areas. The 2003 Chinese Second Arctic Research Expedition experienced the transition of the stratosphereic circulation from a warm anticyclone to a cold cyclone during the ending period of Arctic summertime, a typical establishing process of the polar vortex circulation. The impact of the polar vortex variation on the low-level circulation has been investigated by some scientists through studying the coupling mechanisms of the stratosphere and troposphere. The impact of the Stratospheric Sudden Warming (SFW) events on the polar vortex variation was drawing people's great attention in the fifties of the last century. The Arctic Oscillation (AO) , relating to the variation of the Arctic vortex, has been used to study the impact of the Arctic vortex on climate change. The recent Arctic vortex studies are simply reviewed and some discussions on the Arctic vertex are given in the paper. Some different views and questions are also discussed.

  8. Homoeopathy: Discussion on scientific validation

    Directory of Open Access Journals (Sweden)

    Lex Rutten


    Full Text Available Background: There are diverging opinions about scientific evidence for Homoeopathy, but evidence for conventional medicine is not perfect either. In fact, proof for Homoeopathy is not inferior to conventional. However, the evidence for Homoeopathy has been downplayed by selection of trials (cherry-picking. The effect of Homoeopathy in randomized controlled trials (RCTs, however, is small due to many ineffective prescriptions. This is caused by shortcomings of our Materia Medica and Repertories. Discussion: The hegemony of the RCT is increasingly questioned; it does not provide all answers, especially not for the individual patient. The individual patient wants to know his individual prognosis: Will this medicine work for him? This is even more important than his individual diagnosis. It is possible to assess prognosis scientifically the same way as diagnosis. Prognostic research is based on daily practice; practitioners should have knowledge about statistics to fulfill their role in this process. Conclusion: The discussion in this paper elucidates that RCT has its limitations, especially for the patient whose main concern is recovery/prognosis. Drug validation is a key to improve the outcome of clinical practice in Homoeopathy.

  14. Dispersion in unit disks

    CERN Document Server

    Dumitrescu, Adrian


    We present two new approximation algorithms with (improved) constant ratios for selecting $n$ points in $n$ unit disks such that the minimum pairwise distance among the points is maximized. (I) A very simple $O(n \\log{n})$-time algorithm with ratio 0.5110 for disjoint unit disks. In combination with an algorithm of Cabello \\cite{Ca07}, it yields a $O(n^2)$-time algorithm with ratio of 0.4487 for dispersion in $n$ not necessarily disjoint unit disks. (II) A more sophisticated LP-based algorithm with ratio 0.6495 for disjoint unit disks that uses a linear number of variables and constraints, and runs in polynomial time. The algorithm introduces a novel technique which combines linear programming and projections for approximating distances. The previous best approximation ratio for disjoint unit disks was 1/2. Our results give a partial answer to an open question raised by Cabello \\cite{Ca07}, who asked whether 1/2 could be improved.

    The manganese(II) carbonate, MnCO3.H2O, cobalt(II) carbonate, CoCO3.4H2O, zinc(II) carbonate, ZnCO3 and cadmium(II) carbonate, CdCO3, respectively, were synthesis by a new simple unusual route during the reaction of aqueous solutions of MnX2, CoX2, ZnX2 and CdX2, where (X = Br- and ClO$^{-}_{4}$) with urea at high temperature within ∼ 90°C for 6 h. The infrared spectra of the reaction products clearly indicate the absence of the bands of urea, but show the characteristic bands of ionic carbonate, CO$^{2-}_{3}$. A general mechanism describing the preparation of manganese(II), cobalt(II), zinc(II) and cadmium(II) carbonate compounds are discussed.

  16. To discuss illicit nuclear trafficking

    Energy Technology Data Exchange (ETDEWEB)

    Balatsky, Galya I [Los Alamos National Laboratory; Severe, William R [Los Alamos National Laboratory; Wallace, Richard K [Los Alamos National Laboratory


    The Illicit nuclear trafficking panel was conducted at the 4th Annual INMM workshop on Reducing the Risk from Radioactive and Nuclear Materials on February 2-3, 2010 in Washington DC. While the workshop occurred prior to the Nuclear Security Summit, April 12-13 2010 in Washington DC, some of the summit issues were raised during the workshop. The Communique of the Washington Nuclear Security Summit stated that 'Nuclear terrorism is one of the most challenging threats to international security, and strong nuclear security measures are the most effective means to prevent terrorists, criminals, or other unauthorized actors from acquiring nuclear materials.' The Illicit Trafficking panel is one means to strengthen nuclear security and cooperation at bilateral, regional and multilateral levels. Such a panel promotes nuclear security culture through technology development, human resources development, education and training. It is a tool which stresses the importance of international cooperation and coordination of assistance to improve efforts to prevent and respond to incidents of illicit nuclear trafficking. Illicit trafficking panel included representatives from US government, an international organization (IAEA), private industry and a non-governmental organization to discuss illicit nuclear trafficking issues. The focus of discussions was on best practices and challenges for addressing illicit nuclear trafficking. Terrorism connection. Workshop discussions pointed out the identification of terrorist connections with several trafficking incidents. Several trafficking cases involved real buyers (as opposed to undercover law enforcement agents) and there have been reports identifying individuals associated with terrorist organizations as prospective plutonium buyers. Some specific groups have been identified that consistently search for materials to buy on the black market, but no criminal groups were identified that specialize in nuclear materials or isotope

  18. Selective chelation of Cd(II) and Pb(II) versus Ca(II) and Zn(II) by using octadentate ligands containing pyridinecarboxylate and pyridyl pendants. (United States)

    Ferreirós-Martínez, Raquel; Esteban-Gómez, David; Platas-Iglesias, Carlos; de Blas, Andrés; Rodríguez-Blas, Teresa


    Herein we report the coordination properties toward Cd(II), Pb(II), Ca(II), and Zn(II) of a new octadentate ligand (py-H(2)bcpe) based on a ethane-1,2-diamine unit containing two picolinate and two pyridyl pendants, which is structurally derived from the previous reported ligand bcpe. Potentiometric studies have been carried out to determine the protonation constants of the ligand and the stability constants of the complexes with these cations. The introduction of the pyridyl pendants in bcpe provokes a very important increase of the logK(ML) values obtained for the Pb(II) and Cd(II) complexes, while this effect is less important in the case of the Zn(II) analogue. As a result, py-bcpe shows a certain selectivity for Cd(II) and Pb(II) over Zn(II) while keeping good Pb(II)/Ca(II) and Cd(II)/Ca(II) selectivities, and the new receptor py-bcpe can be considered as a new structural framework for the design of novel Cd(II) and Pb(II) extracting agents. Likewise, the stabilities of the Cd(II) and Pb(II) complexes are higher than those of the corresponding EDTA analogues. The X-ray crystal structure of [Zn(py-bcpe)] shows hexadentate binding of the ligand to the metal ion, the coordination polyhedron being best described as a severely distorted octahedron. However, the X-ray crystal structure of the Pb(II) analogue shows octadentate binding of the ligand to the metal ion. A detailed investigation of the structure in aqueous solution of the complexes by using nuclear magnetic resonance (NMR) techniques and density functional theory (DFT) calculations (B3LYP) shows that while in the Zn(II) complex the metal ion is six-coordinated, in the Pb(II) and Ca(II) analogues the metal ions are eight-coordinated. For the Cd(II) complex, our results suggest that in solution the complex exists as a mixture of seven- and eight-coordinated species. DFT calculations performed both in the gas phase and in aqueous solution have been also used to investigate the role of the Pb(II) lone pair in

    Energy Technology Data Exchange (ETDEWEB)

    Fineman, C.P.


    In the past, safety and relief valves installed in the primary coolant system of light water reactors have performed improperly. As a result, the authors of NUREG-0578 (TMI-2 Lessons Learned Task Force Status Report and Short-Term Recommendations) and, subsequently, NUREG-0737 (Clarification of TMI Action Plan Requirements) recommended development and completion of programs to do two things. First, they should reevaluate the functional performance capabilities of pressurized water reactor safety, relief, and block valves. Second, they should verify the integrity of the pressurizer safety and relief valve piping systems for normal, transient, and accident conditions. This report documents the review of those programs by Lockheed Idaho Technologies Company. Specifically, this report documents the review of the Watts Bar Nuclear Plant, Units 1 and 2, Applicant response to the requirements of NUREG-0578 and NUREG-0737. This review found the Applicant provided an acceptable response reconfirming they met General Design Criteria 14, 15, and 30 of Appendix A to 10 CFR 50 for the subject equipment. It should also be noted Lockheed Idaho performed this review for both Units 1 and 2. However, the applicability of this review to Unit 2 depends on verifying that the Unit 2 as-built system conforms to the Unit 1 design reviewed in this report.

  20. The APGAR rubric for scoring online discussion boards. (United States)

    Phillippi, Julia C; Schorn, Mavis N; Moore-Davis, Tonia


    The World Health Organization has called for a dramatic increase in the number of midwives and supports the use of innovative programs to assist students in achieving midwifery competencies. Online discussion boards are excellent educational tools for stimulating in-depth student engagement. However, complex discussions can be difficult to grade without a well-constructed rubric. The 'discussion-board APGAR' provides clear scoring criteria for discussions of midwifery care. The discussion-board APGAR has 5 components: Application, Professionalism, Group work, Analysis, and Rationale and provides scoring criteria for unacceptable, marginal, and proficient performance. The discussion-board APGAR is based on the Core Competencies for Basic Midwifery Practice in the United States (US), consistent with the International Confederation of Midwives Essential Competencies for Basic Midwifery Practice, and can be adjusted to be congruent with other midwifery standards.

    CERN Multimedia


    Original detector unit of the Instituut voor Kernfysisch Onderzoek (IKO) BOL project. This detector unit shows that silicon detectors for nuclear physics particle detection were already developed and in use in the 1960's in Amsterdam. Also the idea of putting 'strips' onto the silicon for high spatial resolution of a particle's impact on the detector were implemented in the BOL project which used 64 of these detector units. The IKO BOL project with its silicon particle detectors was designed, built and operated from 1965 to roughly 1977. Detector Unit of the BOL project: These detectors, notably the ‘checkerboard detector’, were developed during the years 1964-1968 in Amsterdam, The Netherlands, by the Natuurkundig Laboratorium of the N.V. Philips Gloeilampen Fabrieken. This was done in close collaboration with the Instituut voor Kernfysisch Onderzoek (IKO) where the read-out electronics for their use in the BOL Project was developed and produced.

    showing the increase, considering latency and the length of the observation period. Of further interest are results relating to diseases of the urinary tract such as kidney failure in the NPCSs of Basso bacino del fiume Chienti, Taranto, Milazzo and Priolo. Overall, the results discussed above are consistent with the previous findings pertaining to mortality for 1995-2002. The present analysis also introduces a new element - the study of cancer incidence and hospital discharges - which can tell us a great deal about diseases with high survival rates or non lethal ones. The first is the case of thyroid cancer, which presents increases in both databases and for both genders in a number of NPCSs (Brescia-Caffaro, Laghi di Mantova, Milazzo, Sassuolo- Scandiano and Taranto). The study of cancer incidence and hospital discharges also revealed cancer excesses for melanoma, breast cancer and non Hodgkin lymphoma in Brescia-Caffaro NPCS where PCBs (Polychlorinated biphenyl) are the site's main pollutant. PCBs, according to the 2013 evaluation of the International Agency for Research on Cancer, are ascertained human carcinogens for melanoma and probable carcinogens for breast cancer and non-Hodgkin lymphoma. The results pertaining to cancer incidence in the 17 NPCSs can also be presented using rankings by area or disease analyzed by a multivariate hierarchical Bayesian model. These rankings reveal an overlapping of credibility intervals, such that it is not possible to speak of a limited number of cancer sites or of certain NPCSs as being particularly affected. Every NPCS, therefore, must be considered individually and ordering them by ranking of cancer incidence wouldn't be appropriate. Data collected concerning some of the NPCSs in the context of the SENTIERI Project is so conclusive that remediation measures can immediately be put in place. This is the case in the Biancavilla and Brescia-Caffaro NPCSs. A similar conclusion can be drawn for complex locations such as Taranto

  16. Indigenous healing practice: ayahuasca. Opening a discussion. (United States)

    Prue, Robert; Voss, Richard W


    This essay frames an invitation to pastoral counselors and pastoral theologians to examine connections and perhaps interactions between themselves and traditional shamanic healers who use ayahuasca in their healing ceremonies. Indigenous people in South America have used ayahuasca for centuries, and the ritual has become common among the mestizo populations in urban areas of the Amazon, particularly as a curing ritual for drug addiction (Dobkin de Rios, 1970; Moir, 1998). Like peyote in the United States (Calabrese, 1997) ayahuasca use amongst the indigenous people of the Amazon is a form of cultural psychiatry. A review of the literature reveals very little commentary or discussion of shamanic practice in Pastoral Counseling (Pastoral Theology). The scant literature identifies an antithetical relationship at best. The current authors wonder about the possibility of to including shamanic practices in the context of pastoral counseling? This essay seeks to provide some basic information about the ritual use of ayahuasca and to offer a rationale for pastoral counselors to engage in a dialogue about its utility.

Who is the desirable student and who is constructed as ill-fitting? This article explores discourses that structure the Vision II science classroom, and how different students construct their identities inside these discourses. In the article we consider school science as an order of discourses which restricts and enables what is possible to think and say and what subject-positions those are available and non-available. The results show that students' talk about a SSI about body and health is constituted by several discourses. We have analyzed how school science discourse, body discourse and general school discourse are structuring the discussions. But these discourses are used in different ways depending on how the students construct their identities in relation to available subject positions, which are dependent on how students at the same time are "doing" gender and social class. As an example, middle class girls show resistance against SSI-work since the practice is threatening their identity as "successful students". This article uses a sociopolitical perspective in its discussions on inclusion and exclusion in the practice of Vision II. It raises critical issues about the inherited complexity of SSI with meetings and/or collisions between discourses. Even if the empirical results from this qualitative study are situated in specific cultural contexts, they contribute with new questions to ask concerning SSI and Vision II school science.

The geological exploration units of Shaanxi province have established an economic responsibility appraisal system for the geological exploration units at the grass-roots level, which fits business characteristics. After enterprise-oriented reforms, the geological prospecting units in Shaanxi have consulted the examination system of State-owned Assets Supervision and Administration Commission of the State Council (SASAC), the examination system of Provincial Geological Mining Corporation required for the geological exploration units at the grass-roots level based on the characteristics of reform and industry practices. At the same time, they have properly used the management by objectives, and relevant knowledge of key performance indictor theory. In addition, they have adopted the design idea that ifnancial targets must be the focus, and non-ifnancial indicators should be regarded as supplement. As a result, they have established economic responsibility appraisal system for the geological exploration units at the grass-roots level; and carried out the examination by setting up the basic index and auxiliary index.

    Tao, Terence


    This is part two of a two-volume book on real analysis and is intended for senior undergraduate students of mathematics who have already been exposed to calculus. The emphasis is on rigour and foundations of analysis. Beginning with the construction of the number systems and set theory, the book discusses the basics of analysis (limits, series, continuity, differentiation, Riemann integration), through to power series, several variable calculus and Fourier analysis, and then finally the Lebesgue integral. These are almost entirely set in the concrete setting of the real line and Euclidean spaces, although there is some material on abstract metric and topological spaces. The book also has appendices on mathematical logic and the decimal system. The entire text (omitting some less central topics) can be taught in two quarters of 25–30 lectures each. The course material is deeply intertwined with the exercises, as it is intended that the student actively learn the material (and practice thinking and writing ri...

  8. Helium II level measurement techniques (United States)

    Celik, D.; Hilton, D. K.; Zhang, T.; Van Sciver, S. W.


    In this paper, a survey of cryogenic liquid level measurement techniques applicable to superfluid helium (He II) is given. The survey includes both continuous and discrete measurement techniques. A number of different probes and controlling circuits for this purpose have been described in the literature. They fall into one of the following categories: capacitive liquid level gauges, superconducting wire liquid level gauges, thermodynamic (heat transfer-based) liquid level gauges, resistive gauges, ultrasound and transmission line-based level detectors. The present paper reviews these techniques and their suitability for He II service. In addition to these methods, techniques for measuring the total liquid volume and mass gauging are also discussed.

    Education is particularly important for enlightening wisdom and heritage of national culture of a nation, but as a "second-class citizens", the African-American’ right to receive education was denied when they came to the American continent. The African Americans not only struggle for freedom, but also for the right to receive education at all times. The blacks’right to receive education after World War II has been continuously improved and achieved great progress. The progress in educational advancement is due to the post-war turbulent black civil rights movement and more importantly, the main reason is due to the enhancement of the political and economic status of African Americans;In addition, Postwar America needs high-quality labor of African Americans; Postwar U.S. domestic and international situation have also played a significant role in promoting the educational progress of African Americans;certainly the progress also benefits from the support of liberal American politicians.%教育对于启迪一个民族的智慧和传承民族文化尤为重要,而作为“二等公民”的美国黑人接受教育的权力在其来到美洲大陆,就被剥夺。美国黑人在争取自由的同时,也在无时不刻的争取接受教育的权利。二战后黑人受教育权利不断得到改善,进步明显。这些进步不仅是战后风起云涌的黑人民权运动所致,更主要的是美国黑人自身政治经济地位的提升;战后对于高素质黑人劳动力的需要;同时战后美国国内和国际形势对于黑人教育进步也起到了很大的促进作用;当然也得益于开明美国政治人物的支持。

  14. Differential expression of the L- and S-isoforms of myelin associated glycoprotein (MAG) in oligodendrocyte unit phenotypes in the adult rat anterior medullary velum. (United States)

    Butt, A M; Ibrahim, M; Gregson, N; Berry, M


    We have previously demonstrated differences in the expression of carbonic anhydrase II (CAII) in oligodendrocyte units myelinating small and large diameter fibres in the anterior medullary velum (AMV) of the adult rat (each unit comprises the cell body, processes and myelin sheaths). Others have indicated that myelin composition may also vary with respect to myelin basic protein (MBP) and proteolipid protein (PLP), and the small (S)- and large (L)-isoforms of myelin associated glycoprotein (MAG). In this study, we have determined the expression of myelin proteins in oligodendrocyte unit phenotypes I-IV, which myelinate fibres ranging in diameter from 0.3-12 microns diameter in the AMV, by using double immunolabelling for Rip, which labels entire units, and MBP, PLP, myelin oligodendrocyte glycoprotein (MOG), L-MAG and S-MAG. We show differences in the expression of L- and S-MAG in units which myelinate different diameter fibres: (1) type I/II units myelinating small diameter fibres had a L-MAG+/S-MAG-/CAII+ phenotype; (2) type II/III units myelinating different diameter fibres had a L-MAG+/S-MAG+/CAII+ phenotype; (3) type III/IV units myelinated large diameter fibres had a L-MAG+/S-MAG+/CAII- phenotype. All units, irrespective of fibre diameter, expressed Rip, MBP, PLP and MOG. The results indicate that type I-IV units may be variants of a single oligodendrocyte population and that phenotypic differences are determined by the diameter of fibres within the unit. The possible significance of metabolic and biochemical differences between oligodendrocytes myelinating small and large diameter axons are discussed with reference to the pathology of demyelination.

  19. Synthesis and processing of intelligent cost-effective structures phase II (SPICES II): smart materials aircraft applications evaluation (United States)

    Dunne, James P.; Jacobs, Steven W.; Baumann, Erwin W.


    The second phase of the synthesis and processing of intelligent cost effective structures (SPICES II) program sought to identify high payoff areas for both naval and aerospace military systems and to evaluate military systems and to evaluate the benefits of smart materials incorporation based on their ability to redefine the mission scenario of the candidate platforms in their respective theaters of operation. The SPICES II consortium, consisting of The Boeing Company, Electric Boat Corporation, United Technologies Research Center, and Pennsylvania State University, surveyed the state-of-the-art in smart structures and evaluated potential applications to military aircraft, marine and propulsion systems components and missions. Eleven baseline platforms comprising a wide variety of missions were chosen for evaluation. Each platform was examined in its field of operation for areas which can be improved using smart materials insertion. Over 250 smart materials applications were proposed to enhance the platforms. The applications were examined and, when possible, quantitatively analyzed for their effect on mission performance. The applications were then ranked for payoff, risk, and time frame for development and demonstration. Details of the efforts made in the SPICES II program pertaining to smart structure applications on military and transport aircraft will be presented. A brief discussion of the core technologies will be followed by presentation of the criteria used in ranking each application. Thereafter, a selection of the higher ranking proposed concepts are presented in detail.

  20. Synthesis, structure and properties of {M4O4} cubanes containing nickel(II) and cobalt(II). (United States)

    Isele, Katharina; Gigon, Fabienne; Williams, Alan F; Bernardinelli, Gérald; Franz, Patrick; Decurtins, Silvio


    A survey of the crystal structures containing simple {M4O4} cubane units is reported. It shows that the average M-M distance in these complexes is relatively constant for a given metal ion M. The structures are all distorted from the idealised cube to a T(d) structure, and most show a further distortion which, however, usually maintains some elements of symmetry. A system for classifying the different types of ligand in these complexes is proposed. Two new cubanes of cobalt(II) and nickel(II) with the ligand (R,R)-bis-1,2-(1-methylbenzimidazol-2-yl)ethane-1,2-diol, (R,R)- or its enantiomer have been isolated and the crystal structure of the cobalt(II) complex confirms the cubane structure. Electronic, CD and (1)H NMR spectra and magnetic susceptibility data are reported. The magnetic data for these and other compounds in the literature are discussed in terms of the structural parameters.

    Full Text Available Background: Multi-drug resistant strains of Acinetobacter spp. have created therapeutic problems worldwide. The objective of this study was to detect integrons  in Acinetobacter  spp. isolates  from Ventilator-Associated  Pneu- monia patients using PCR method.Methods: A total 51 Bronchoalveolar lavage samples were obtained from pa-tients in ICU and examined for Acinetobacter spp. infection by biochemical and PCR methods using blaOXA51-like primers. Antimicrobial susceptibility testing was performed using disk diffusion and MIC methods.Results: Among 51 patients with VAP (62.7% males, 35.2% females, mean age 53 year, 50 (98% were positive, with a high prevalence of gram-nega- tive bacteria, mainly Acinetobacter spp. (70%, from which A. baumani was detected in 34 (68% and A. lwoffii in 1 (2% of isolates. More than 90% of isolates were resistant to imipenem,  piperacillin+tazobactam,  third genera- tion cephalosporins and gentamicin, while the most effective antibiotic was colistin (100%. The correlation coefficient between disk diffusion and MIC was 0.808 (p = 0.001. Three Acinetobacter isolates (8% harbored integrase I gene but none of isolates contained Class II or III integrons.Conclusion: The results showed that colistin was an effective antibiotic andcan be used for treatment  of patients in ICU. Due to the high number of MDR isolates lacking Integrons it can be concluded that although class I in- tegrons are important among clinical isolates of A. baumannii, they have no significant  role  in  dissemination  of  antibiotic  resistance  genes  in  Rasoul Akram  Hospital in Tehran, Iran. The presence of IntI in A. lwoffii may be related to transfer of integron to A. baumannii which can be considered as an important threat for hospitalized patients.

  4. Calibration campaign against the international prototype of the kilogram in anticipation of the redefinition of the kilogram, part II: evolution of the BIPM as-maintained mass unit from the 3rd periodic verification to 2014 (United States)

    de Mirandés, Estefanía; Barat, Pauline; Stock, Michael; Milton, Martin J. T.


    In 2014 the Bureau International des Poids et Mesures (BIPM) carried out a calibration campaign using the international prototype of the kilogram (IPK). This is the second part in a series of publications describing the results of that campaign. As reported in [Metrologia 52 310–6] following the comparisons between the IPK and its official copies, it was found that the BIPM ‘as-maintained mass unit’ was offset by 35 mg from the mass of the IPK in 2014. We report here the results of an investigation into this offset that has considered all data available from internal BIPM mass comparisons carried out between 1992 and 2014. This has enabled us to model the evolution of the offset in the as-maintained mass unit and to identify some possible reasons why it has developed. We also report how the model has been used to estimate corrections to all 1 kg mass calibration certificates issued by the BIPM during this period.

    Bakemeier, R F; Kupchella, C E; Chamberlain, R M; Gallagher, R E; O'Donnell, J F; Parker, J A; Hill, G J; Brooks, C M


    A survey has been conducted of cancer education programs for medical students in United States medical schools by the American Association for Cancer Education with grant support from the Department of Detection and Treatment of the American Cancer Society (formerly the Professional Education Department). Two questionnaires were used, an Educational Resources Questionnaire (ERQ), which 126 of the 128 medical schools completed and returned, and a Faculty and Curriculum Questionnaire (FCQ), which was completed and returned by 1,035 faculty members who had been named as active in undergraduate medical student cancer education by respondents in each school who had been designated by the Dean's Office to complete the ERQ. Overall conclusions included: (1) increased coordination of cancer education activities is a major need in many schools; (2) there is widespread interest in the further development of cancer education objectives; (3) development of a national cancer education curriculum is needed; (4) there is interest in the development of improved instructional materials and methods; (5) development of evaluation methods is needed for cancer education programs; and (6) an ongoing funding process is needed to provide support for interdepartmental coordination of cancer education activities. Cancer prevention and detection topics were ranked above cancer treatment in plans for future curriculum emphasis. More detailed conclusions and recommendations are provided in this publication and three subsequent articles in this issue of the Journal of Cancer Education.

    Sanders, Mark Callis [Sanders Engineering, Las Vegas, NV (United States); Sanders, Charlotta E. [Nevada Univ., Las Vegas (United States). Dept. of Mechanical Engineering


    The management of spent nuclear fuel (SNF) and nuclear wastes demands a strategy to provide for the safe, secure, and permanent disposal of radioactive material from power generation, defense uses, and other activities. Nation states have taken different paths to nuclear waste management and are at various stages of the development of a nuclear waste management strategy. A strategy may include developing a geological repository, nuclear fuel reprocessing, interim storage, as well as discussions of the creation of a multinational storage facility. The paper provides an overview of the strategy used (or being developed) and its place within the legal framework. The paper concludes that though each nation state must look outward to its shared international obligations, there must also be an inward reflection of a nation state to its own traditions, customs, and legal/law making regimes.

  7. Photoinduced energy- and electron-transfer processes in dinuclear Ru(II)-Os(II), Ru(II)-Os(III), and Ru(III)-Os(II) trisbipyridine complexes containing a shape-persistent macrocyclic spacer. (United States)

    Venturi, Margherita; Marchioni, Filippo; Ferrer Ribera, Belén; Balzani, Vincenzo; Opris, Dorina M; Schlüter, A Dieter


    The PF6- salt of the dinuclear [(bpy)2Ru(1)Os(bpy)2]4+ complex, where 1 is a phenylacetylene macrocycle which incorporates two 2,2'-bipyridine (bpy) chelating units in opposite sites of its shape-persistent structure, was prepared. In acetonitrile solution, the Ru- and Os-based units display their characteristic absorption spectra and electrochemical properties as in the parent homodinuclear compounds. The luminescence spectrum, however, shows that the emission band of the Ru(II) unit is almost completely quenched with concomitant sensitization of the emission of the Os(II) unit. Electronic energy transfer from the Ru(II) to the Os(II) unit takes place by two distinct processes (k(en) = 2.0x10(8) and 2.2x10(7) s(-1) at 298 K). Oxidation of the Os(II) unit of [(bpy)2Ru(1)Os(bpy)2]4+ by Ce(IV) or nitric acid leads quantitatively to the [(bpy)2Ru(II)(1)Os(III)(bpy)2]5+ complex which exhibits a bpy-to-Os(III) charge-transfer band at 720 nm (epsilon(max) = 250 M(-1) cm(-1)). Light excitation of the Ru(II) unit of [(bpy)2Ru(II)(1)Os(III)(bpy)2]5+ is followed by electron transfer from the Ru(II) to the Os(III) unit (k(el,f) = 1.6x10(8) and 2.7x10(7) s(-1)), resulting in the transient formation of the [(bpy)2Ru(III)(1)Os(II)(bpy)2]5+ complex. The latter species relaxes to the [(bpy)2Ru(II)(1)Os(III)(bpy)2]5+ one by back electron transfer (k(el,b) = 9.1x10(7) and 1.2x10(7) s(-1)). The biexponential decays of the [(bpy)2*Ru(II)(1)Os(II)(bpy)2]4+, [(bpy)2*Ru(II)(1)Os(III)(bpy)2]5+, and [(bpy)2Ru(III)(1)Os(II)(bpy)2]5+ species are related to the presence of two conformers, as expected because of the steric hindrance between hydrogen atoms of the pyridine and phenyl rings. Comparison of the results obtained with those previously reported for other Ru-Os polypyridine complexes shows that the macrocyclic ligand 1 is a relatively poor conducting bridge.

  15. Use of APACHE II and SAPS II to predict mortality for hemorrhagic and ischemic stroke patients. (United States)

    Moon, Byeong Hoo; Park, Sang Kyu; Jang, Dong Kyu; Jang, Kyoung Sool; Kim, Jong Tae; Han, Yong Min


    We studied the applicability of the Acute Physiology and Chronic Health Evaluation II (APACHE II) and Simplified Acute Physiology Score II (SAPS II) in patients admitted to the intensive care unit (ICU) with acute stroke and compared the results with the Glasgow Coma Scale (GCS) and National Institutes of Health Stroke Scale (NIHSS). We also conducted a comparative study of accuracy for predicting hemorrhagic and ischemic stroke mortality. Between January 2011 and December 2012, ischemic or hemorrhagic stroke patients admitted to the ICU were included in the study. APACHE II and SAPS II-predicted mortalities were compared using a calibration curve, the Hosmer-Lemeshow goodness-of-fit test, and the receiver operating characteristic (ROC) curve, and the results were compared with the GCS and NIHSS. Overall 498 patients were included in this study. The observed mortality was 26.3%, whereas APACHE II and SAPS II-predicted mortalities were 35.12% and 35.34%, respectively. The mean GCS and NIHSS scores were 9.43 and 21.63, respectively. The calibration curve was close to the line of perfect prediction. The ROC curve showed a slightly better prediction of mortality for APACHE II in hemorrhagic stroke patients and SAPS II in ischemic stroke patients. The GCS and NIHSS were inferior in predicting mortality in both patient groups. Although both the APACHE II and SAPS II systems can be used to measure performance in the neurosurgical ICU setting, the accuracy of APACHE II in hemorrhagic stroke patients and SAPS II in ischemic stroke patients was superior.

  18. Food packaging regulation in the United States and the European Union. (United States)

    Heckman, Jerome H


    The regulation of food packaging has, indeed, become a global subject as the world's commercial channels have broadened since World War II. The first comprehensive regulatory statute governing the area was the Food Additives Amendment of 1958 in the United States, a modification of the 1938 Federal Food, Drug, and Cosmetic Act. Germany, Italy, The Netherlands, and Belgium began regulatory activity in the early 1960s and the European Community set in motion its own work in this direction beginning in 1976. Companies in the United States and the Europe have been struggling with each of the laws since then. The regulatory systems employed on the two continents are superficially similar but this is far from the truth in actual practice. Each has its own special history and set of exemptions; they vary tremendously. Each has its cadre of supporters as well but a considerable lack of understanding afflicts regulators and the regulated on both sides of the Atlantic. This three part report first discusses the history of the United States system and its characteristics; Book II covers the history of European Union regulations and their salient features; and Book III highlights the commonalities and differences in the systems, discusses their scientific basing points, and makes some recommendations as to how they can be brought closer together in the interests of harmonization and the removal of unnecessary trade barriers.

The special parts houses an inlet and/or outlet for cooling fluid. The space between an inner wall of the envelope and a central opening of the cable is filled with cooling fluid. The special part at the end connecting to the cryostat houses an inlet or outlet, splitting cooling flow into cable annular flow and termination annular flow.

  2. Psychometric properties of the Beck Depression Inventory II (BDI-II) among community-dwelling older adults. (United States)

    Segal, Daniel L; Coolidge, Frederick L; Cahill, Brian S; O'Riley, Alisa A


    The psychometric properties of the Beck Depression Inventory-II (BDI-II) as a self-administered screening tool for depressive symptoms were examined in a sample of community-dwelling older and younger adults. Participants completed the BDI-II, the Center for Epidemiologic Studies Depression Scale, the Coolidge Axis II Inventory, the Perceived Stress Scale, and the Short Psychological Well-Being Scale. Internal reliability of the BDI-II was found to be good among older and younger adults. The average BDI-II depression score did not differ between younger and older adults. Solid evidence for convergent and discriminant validity was demonstrated by correlations between the BDI-II with the other measures. The BDI-II appears to have strong psychometric support as a screening measure for depression among older adults in the general population. Implications for using the BDI-II as an assessment instrument in behaviorally based psychotherapy are discussed.

  5. Efficiency of energy funneling in the photosystem II supercomplex of higher plants

    CERN Document Server

    Kreisbeck, Christoph


    The investigation of energy transfer properties in photosynthetic multi-protein networks gives insight into their underlying design principles.Here, we discuss excitonic energy transfer mechanisms of the photosystem II (PS-II) C$_2$S$_2$M$_2$ supercomplex, which is the largest isolated functional unit of the photosynthetic apparatus of higher plants.Despite the lack of a decisive energy gradient in C$_2$S$_2$M$_2$, we show that the energy transfer is directed by relaxation to low energy states. C$_2$S$_2$M$_2$ is not organized to form pathways with strict energetic downhill transfer, which has direct consequences on the transfer efficiency, transfer pathways and transfer limiting steps. The exciton dynamics is sensitive to small structural changes, which, for instance, are induced by the reorganization of vibrational coordinates. In order to incorporate the reorganization process in our numerical simulations, we go beyond rate equations and use the hierarchically coupled equation of motion approach (HEOM). Wh...

    Rainmaking, hail busting, fog lifting, snowpack enhancing, lightning suppressing, hurricane control. At the lunatic fringe of scientific discussion in the early twentieth century--and the subject of newspaper articles with tones ranging from skeptical titters to awestruck wonder--weather modification research became more serious after World War II. In the United States, the 'seeds' of silver iodide and dry ice purported to enhance rainfall and bust hailstorms soon became seeds of controversy from which sprouted attempts by federal, state and local government to control the controllers and exploit 'designer weather' for their own purposes.

  9. Giromill wind tunnel test and analysis. Volume II. Technical discussion. Final report, June 1976--October 1977

    Energy Technology Data Exchange (ETDEWEB)

    Moran, W.A.


    A wind tunnel test of a Giromill rotor was conducted. The objective of this test was to substantiate the performance computed by the Larsen cyclogiro vortex theory. Additional objectives were to obtain performance comparison data between the Giromill, a sinusoidal blade modulation Giromill, a Darrieus rotor, and a modified Darrieus rotor that flips the blades a few degrees. A three bladed Giromill rotor having a diameter of 2.13 m (7 ft) and a span of 1.52 m (5 ft) was tested in the McDonnell Aircraft Company 15 x 20 ft Mini Speed Wind Tunnel. The blade modulations were accomplished through use of a cam and push rod arrangement. Replaceable cams provided the desired blade modulation at the various operating points. Various operating conditions were achieved by adjusting the rotor RPM and tunnel speed. The results show that the Giromill has good performance, equal to or much better than that predicted by theory, and outperforms the other types of vertical axis wind turbines tested.

  5. Chinese women's participation in fertility discussions. (United States)

    Li, L


    In an attempt to better understand the process through which the family planning (FP) programs and socioeconomic developments in China affect fertility, women's participation in fertility discussions with their husbands are examined as an intermediate factor in a study based on results of a random survey of 6654 ever-married women of reproductive age from 7 cities and 30 counties of Guangdong. First, it must be noted that Chinese couples do have individual choices (albeit quite limited ones) about their fertility; they can choose to follow or ignore government policy or they can choose to remain childless. The present study has 3 major hypotheses: 1) the more a woman is involved in fertility discussions with her husband, the fewer children she will have; 2) urban women with a higher educational status will be more likely to have such discussions; and 3) women who are contacted individually by FP personnel are more likely to be involved in fertility discussions. After a discussion of data collection and variables (number of living children, education of wife and husband, age at marriage, residence, living with parents, contacted by FP personnel, and discussion with husband), the results are presented in terms of zero-order correlation coefficients indicating their relationships. The bivariate analysis supported the hypotheses. Multiple regression analysis showed that age at marriage, education of wives and husbands, FP contacts, and participation in discussions remain significant fertility determinants (but the correlation between fertility and residence becomes trivial). A further regression model indicated that a woman's educational attainment is the most significant positive indication of their participation in fertility discussions. These results imply that as women's status continues to improve in China and the deeply-rooted patriarchal tradition loses hold, increased gender equity and education will influence a fertility decline. FP personnel could also

  9. Fundamental units: physics and metrology

    CERN Document Server

    Okun, Lev Borisovich


    The problem of fundamental units is discussed in the context of achievements of both theoretical physics and modern metrology. On one hand, due to fascinating accuracy of atomic clocks, the traditional macroscopic standards of metrology (second, metre, kilogram) are giving way to standards based on fundamental units of nature: velocity of light $c$ and quantum of action $h$. On the other hand, the poor precision of gravitational constant $G$, which is widely believed to define the ``cube of theories'' and the units of the future ``theory of everything'', does not allow to use $G$ as a fundamental dimensional constant in metrology. The electromagnetic units in SI are actually based on concepts of prerelativistic classical electrodynamics such as ether, electric permitivity and magnetic permeability of vacuum. Concluding remarks are devoted to terminological confusion which accompanies the progress in basic physics and metrology.

    Bieniosek, F. M.; Honig, J.; Theby, E. A.


    This article discusses improvements in the efficiency, output power, and operational flexibility of MEDEA II, a double-pulse electron beam accelerator at McDonnell Douglas Research Laboratories. A modified charging circuit, based on the triple-resonance pulse transformer concept, was implemented on both of MEDEA II's two stages. The output switches were modified to increase maximum output voltages, and a new, second output switch with asymmetric breakdown characteristics was developed. To avoid degradation of the second-pulse output waveform at the diode, a keep-alive circuit was installed. The effects of diode closure on double-pulse operation are also discussed.

    رضا پیشقدم


    Full Text Available The major aim of this study was to investigate the effect of literary discussion on critical thinking. To this end, two classes (experimental and control groups were selected from College of Ferdowsi University. In both groups literature was used as supplementary homework. Students were supposed to read short stories and poems at home and present them in class. The students in the experimental group were discussing the materials in class and the students in the control group only memorized the texts and retold them. At the end of the term, the students were asked to take a questionnaire on critical thinking. The results demonstrated that there was a significant difference between means of two groups, implying that literary discussion can enhance critical thinking. Finally, results were discussed in the context of education in Iran and some suggestions were made.

  14. Learning Styles and Online Discussion Posts

    Directory of Open Access Journals (Sweden)

    Herbert Rau


    Full Text Available Scholars have suggested models proposing a variety of learning styles for humans. Human Dynamics is one such model, and it has been suggested within its model that one style of learning is enhanced by discussion among learners. While this style of learning may be accomplished relatively easily in an on-campus person-to-person situation, it is not clear how a discussion mode (online posts of learning might be accomplished in an online format. A study of more than 9,000 posts from 240 students in 11 different online classes was conducted to determine whether differences in online discussion posts by individuals with different learning styles were evident. Results of the study suggest that discussion post activity, if managed with suitable rubrics and guiding principles, and augmented by appropriate modeling behavior, is an effective teaching mode for all dynamics, but seem to be a more successful learning mode for individuals of Physically Centered dynamics.

  16. Application of mesoporous SBA-15 silica functionalized with 4-amino-2-mercaptopyrimidine for the adsorption of Cu(II), Zn(II), Cd(II), Ni(II), and Pb(II) from water. (United States)

    Jorgetto, Alexandre de Oliveira; Pereira, Silvana Pontes; Silva, Rafael Innocenti Vieira da; Saeki, Margarida Juri; Martines, Marco Antonio Utrera; Pedrosa, Valber de Albuquerque; Castro, Gustavo Rocha de


    This work reports the sol-gel synthesis of a SBA-15 silica, and its functionalization with 4-amino-2-mercaptopyrimidine to perform adsorption of metal species from aqueous media. The functionalization of the material was confirmed by FTIR and superficial area measurements. The final material was tested through batch experiments to uncover its adsorptive properties towards the adsorption of Cu(II), Cd(II), Zn(II), Pb(II) and Ni(II). Contact time and pH conditions were investigated, and the material presented slow adsorption kinetics, which was best described by the pseudo-second order model. In addition, at pH 5 - 6, the adsorption of the metal ions was favored. Under optimized conditions, the material had its maximum adsorption capacities determined for all metal species studied, and the obtained values were 13.0 µmol g(-1) for Zn(II), 12.3 µmol g(-1) for Cu(II), 3.45 µmol g(-1) for Ni(II), 2.45 µmol g(-1) for Pb(II) and 0.60 µmol g(-1) for Cd(II). The capacity differences between each metal ion were discussed in terms of their ionic radii and Person's soft/hard acids/bases concept.

    The Options Study has been conducted for the purpose of evaluating the potential of alternative integrated nuclear fuel cycle options to favorably address the issues associated with a continuing or expanding use of nuclear power in the United States. The study produced information that can be used to inform decisions identifying potential directions for research and development on such fuel cycle options. An integrated nuclear fuel cycle option is defined in this study as including all aspects of the entire nuclear fuel cycle, from obtaining natural resources for fuel to the ultimate disposal of used nuclear fuel (UNF) or radioactive wastes. Issues such as nuclear waste management, especially the increasing inventory of used nuclear fuel, the current uncertainty about used fuel disposal, and the risk of nuclear weapons proliferation have contributed to the reluctance to expand the use of nuclear power, even though it is recognized that nuclear power is a safe and reliable method of producing electricity. In this Options Study, current, evolutionary, and revolutionary nuclear energy options were all considered, including the use of uranium and thorium, and both once-through and recycle approaches. Available information has been collected and reviewed in order to evaluate the ability of an option to clearly address the challenges associated with the current implementation and potential expansion of commercial nuclear power in the United States. This Options Study is a comprehensive consideration and review of fuel cycle and technology options, including those for disposal, and is not constrained by any limitations that may be imposed by economics, technical maturity, past policy, or speculated future conditions. This Phase II report is intended to be used in conjunction with the Phase I report, and much information in that report is not repeated here, although some information has been updated to reflect recent developments. The focus in this Options Study was to

  7. Advanced Direct Liquefaction Concepts for PETC Generic Units - Phase II

    Energy Technology Data Exchange (ETDEWEB)



    The results of Laboratory and Bench-Scale experiments and supporting technical and economic assessments conducted under DOE Contract No. DE-AC22-91PC91040 are reported for the period July 1, 1997 to September 30, 1997. This contract is with the University of Kentucky Research Foundation which supports work with the University of Kentucky Center for Applied Energy Research, CONSOL, Inc., LDP Associates, and Hydrocarbon Technologies, Inc. This work involves the introduction into the basic two stage liquefaction process several novel concepts which include dispersed lower-cost catalysts, coal cleaning by oil agglomeration, and distillate hydrotreating and dewaxing. Results are reported from experiments in which various methods were tested to activate dispersed Mo precursors. Several oxothiomolybdates precursors having S/Mo ratios from two to six were prepared. Another having a S/Mo ratio of eleven was also prepared that contained an excess of sulfur. In the catalyst screening test, none of these precursors exhibited an activity enhancement that might suggest that adding sulfur into the structure of the Mo precursors would be beneficial to the process. In another series of experiments, AHM impregnated coal slurried in the reaction mixture was pretreated withH S/H under pressure and successively heated for 30 min at 120, 250 2 2 and 360 C. THF conversions in the catalyst screening test were not affected while resid conversions o increased such that pretreated coals impregnated with 100 ppm Mo gave conversions equivalent to untreated coals impregnated with 300 ppm fresh Mo. Cobalt, nickel and potassium phosphomolybdates were prepared and tested as bimetallic precursors. The thermal stability of these compounds was evaluated in TG/MS to determine whether the presence of the added metal would stabilize the Keggin structure at reaction temperature. Coals impregnated with these salts showed the Ni and Co salts gave the same THF conversion as PMA while the Ni salt gave higher resid conversion than the other salts and untreated PMA. To activate PMA, a series of sulfided PMA materials was prepared by subjecting the crystalline acid to H S/H at 125-450 C. The chemistries 2 2 o of these partially sulfided materials are reported as well as the reactivity of several impregnated coals. None of the coals impregnated with these sulfided PMA materials gave conversions that exceeded PMA. Reports covering work by the subcontractors for this reporting period have not been received. A report from CONSOL covering a previous reporting period is included.

  17. Thermal decomposition of solid solutions in systems of Fe(II), Co(II), and Ni(II) hydrogen maleates with the formation of bimetallic nanoparticles (United States)

    Yudanova, L. I.; Logvinenko, V. A.; Sheludyakova, L. A.; Ishchenko, A. V.; Rudina, N. A.


    XRD phase analysis and thermal analysis are used to confirm the formation of a continuous series of solid solutions in which one cation is substituted for another in the systems Co(II) hydrogen maleate-Ni(II) hydrogen maleate; Fe(II) hydrogen maleate-Co(II) hydrogen maleate; and Fe(II) hydrogen maleate-Ni(II) hydrogen maleate. The unit cell volume of these solid solutions is shown to depend linearly on their composition. The linear character of changes in the initial temperatures of dehydration and thermal decomposition is established. Using the example of the first of these systems, it is shown that when heated, bimetallic nanoparticles embedded in the polymeric matrix of composites obtained via the thermal decomposition of solid solutions of hydrogen maleates undergo a second-order phase transition, resulting in decomposition of the solid solutions of metals at the Curie temperature.

  1. High Tc ferrimagnetic organic-inorganic hybrid materials with MnII-L-MnII and MnII-NC-NbIV linkages (L=pyrazine, pyrazine-N,N'-dioxide, bipyrimidine). (United States)

    Podgajny, Robert; Pinkowicz, Dawid; Korzeniak, Tomasz; Nitek, Wojciech; Rams, Michał; Sieklucka, Barbara


    A series of heterobimetallic, cyano-bridged 3D inorganic-organic hybrid networks with MnII-L-MnII and MnII-NC-NbIV linkages are reported. Reaction of [Mn(H2O)6]2+ with [Nb(CN)8]4- in the presence of organic linker L (pyrazine (pyz), pyrazine-N,N'-dioxide (pzdo), and 2,2'-bipyrimidine (bpym)) in H2O affords {MnII2(pz)2(H2O)4[NbIV(CN)8]}.pz.3H2O (1), {MnII2(pzdo)(H2O)4[NbIV(CN)8]}.5H2O (2), and {MnII2(bpym)(H2O)2[NbIV(CN)8]} (3), respectively. 1-3 were examined by X-ray crystallography and vibrational and magnetochemical studies. 1 is characterized by the coexistence of 3D inorganic cyano-bridged and 1D organic [Mn-(micro-pyz)]n2n+ sublattices along with the presence of monocoordinated and crystallization molecules of pyrazine. Assemblies 2 and 3 exhibit dimeric {MnII2-(micro-L)}4+ coordination motifs. The magnetic behavior of heterobimetallic 1-3 complexes is dominated by antiferromagnetic coupling between MnII and NbIV centers mediated by cyano bridges, resulting in long-range ferrimagnetic ordering with a high TC of 27 (1), 37 (2), and 50 K (3). The magneto-structural correlation leads to the conclusion that the magnitude of TC is related to the type of coordination polyhedra of [Nb(CN)8] moieties (SAPR (1), intermediate between SAPR and DD (2), and DD (3)), the relative number of cyano bridges per Mn2Nb unit, and coexistence of inorganic and organic connectivity. FC/ZFC responses appear to be sensitive to the degree of organic connectivity. The discussion of magneto-structural correlation is based on the spin-density properties of adequate heterobimetallic systems containing octacyanometalates.

    Learning unit: Thin lenses "Why objects seen through lenses are sometimes upright and sometimes reversed" Nita Laura Simona National College of Arts and Crafts "Constantin Brancusi", Craiova, Romania 1. GEOMETRIC OPTICS. 13 hours Introduction (models, axioms, principles, conventions) 1. Thin lenses (Types of lenses. Defining elements. Path of light rays through lenses. Image formation. Required physical quantities. Lens formulas). 2. Lens systems (Non-collated lenses. Focalless systems). 3. Human eye (Functioning as an optical system. Sight defects and their corrections). 4. Optical instruments (Characteristics exemplified by a magnifying glass. Paths of light rays through a simplified photo camera. Path of light rays through a classical microscope) (Physics curriculum for the IXth grade/ 2011). This scenario exposes a learning unit based on experimental sequences (defining specific competencies), as a succession of lessons started by noticing a problem whose solution assumes the setup of an experiment under laboratory conditions. Progressive learning of theme objectives are realised with sequential experimental steps. The central cognitive process is the induction or the generalization (development of new knowledge based on observation of examples or counterexamples of the concept to be learnt). Pupil interest in theme objectives is triggered by problem-situations, for example: "In order to better see small objects I need a magnifying glass. But when using a magnifier, small object images are sometimes seen upright and sometimes seen reversed!" Along the way, pupils' reasoning will converge to the idea: "The image of an object through a lens depends on the relative distances among object, lens, and observer". Associated learning model: EXPERIMENT Specific competencies: derived from the experiment model, in agreement with the following learning unit steps I.

    Energy Technology Data Exchange (ETDEWEB)

    Lopez Martinez, A.


    At present energy production is based on the combustion of fossil fuels and is the main cause of greenhouse gas emissions, which is to say it is the main cause of the climate change that is affecting the planet. On a worldwide scale, the use of solar concentration systems with systems capable of dissociating water is considered, from both an energy and an economic standpoint, as the most important long-term goal in the production of solar fuels to reduce the costs of hydrogen and to ensure practically zero carbon dioxide emissions. The Hydrosol II project has the largest pilot plant of its kind, and the Hydrosol II reactors will be capable of breaking up the water molecule on the basis of thermochemical cycles at moderate temperatures. The Hydrosol II project pilot plant is now a reality, located in the SSPS heliostats field of the Almeria Solar Platform. (Author)

    We use seeing-free high spatial resolution Ca ii H data obtained by the Sunrise observatory to determine properties of slender fibrils in the lower solar chromosphere. In this work we use intensity images taken with the SuFI instrument in the Ca ii H line during the second scientific flight of the Sunrise observatory to identify and track elongated bright structures. After identification, we analyze theses structures to extract their morphological properties. We identify 598 slender Ca ii H fibrils (SCFs) with an average width of around 180 km, length between 500 and 4000 km, average lifetime of ≈400 s, and average curvature of 0.002 arcsec‑1. The maximum lifetime of the SCFs within our time series of 57 minutes is ≈2000 s. We discuss similarities and differences of the SCFs with other small-scale, chromospheric structures such as spicules of type I and II, or Ca ii K fibrils.

  14. Conflicting perspectives compromising discussions on cardiopulmonary resuscitation.

    LENUS (Irish Health Repository)

    Groarke, J


    Healthcare professionals, patients and their relatives are expected to discuss resuscitation together. This study aims to identify the differences in the knowledge base and understanding of these parties. Questionnaires examining knowledge and opinion on resuscitation matters were completed during interviews of randomly selected doctors, nurses and the general public. 70% doctors, 24% nurses and 0% of a public group correctly estimated survival to discharge following in-hospital resuscitation attempts. Deficiencies were identified in doctor and nurse knowledge of ethics governing resuscitation decisions. Public opinion often conflicts with ethical guidelines. Public understanding of the nature of cardiopulmonary arrests and resuscitation attempts; and of the implications of a \\'Do Not Attempt Resuscitation (DNAR)\\' order is poor. Television medical dramas are the primary source of resuscitation knowledge. Deficiencies in healthcare professionals\\' knowledge of resuscitation ethics and outcomes may compromise resuscitation decisions. Educational initiatives to address deficiencies are necessary. Parties involved in discussion on resuscitation do not share the same knowledge base reducing the likelihood of meaningful discussion. Public misapprehensions surrounding resuscitation must be identified and corrected during discussion.

    Heller, Jan C


    Discussing the theological beliefs that ground Catholic moral principles can make some people uncomfortable, even while others will appreciate it. But these reactions will sometimes be revealed not as the emotions they are, but as objections to the relative independence or dependence of morality on foundational beliefs. In the end, context should dictate whether one displays the theological beliefs that ground Catholic moral principles.

  16. Dinuclear cadmium(II), zinc(II), and manganese(II), trinuclear nickel(II), and pentanuclear copper(II) complexes with novel macrocyclic and acyclic Schiff-base ligands having enantiopure or racemic camphoric diamine components. (United States)

    Jiang, Jue-Chao; Chu, Zhao-Lian; Huang, Wei; Wang, Gang; You, Xiao-Zeng


    Four novel [3 + 3] Schiff-base macrocyclic ligands I-IV condensed from 2,6-diformyl-4-substituted phenols (R = CH(3) or Cl) and enantiopure or racemic camphoric diamines have been synthesized and characterized. Metal-ion complexations of these enantiopure and racemic [3 + 3] macrocyclic ligands with different cadmium(II), zinc(II), manganese(II), nickel(II), and copper(II) salts lead to the cleavage of Schiff-base C horizontal lineN double bonds and subsequent ring contraction of the macrocyclic ligands due to the size effects and the spatial restrictions of the coordination geometry of the central metals, the steric hindrance of ligands, and the counterions used. As a result, five [2 + 2] and one [1 + 2] dinuclear cadmium(II) complexes (1-6), two [2 + 2] dinuclear zinc(II) (7 and 8), and two [2 + 2] dinuclear manganese(II) (9 and 10) complexes together with one [1 + 1] trinuclear nickel(II) complex (11) and one [1 + 2] pentanuclear copper(II) complex (12), bearing enantiopure or racemic ligands, different substituent groups in the phenyl rings, and different anionic ligands (Cl(-), Br(-), OAc(-), and SCN(-)), have been obtained in which the chiral carbon atoms in the camphoric backbones are arranged in different ways (RRSS for the enantiopure ligands in 1, 2, 4, 5, and 7-10 and RSRS for the racemic ligands in 3, 6, 11, and 12). The steric hindrance effects of the methyl group bonded to one of the chiral carbon atoms of camphoric diamine units are believed to play important roles in the formation of the acyclic [1 + 1] trinuclear complex 11 and [1 + 2] dinuclear and pentanuclear complexes 6 and 12. In dinuclear cadmium(II), zinc(II), and manganese(II) complexes 1-10, the sequence of separations between the metal centers is consistent with that of the ionic radii shortened from cadmium(II) to manganese(II) to zinc(II) ions. Furthermore, UV-vis, circular dichroism, (1)H NMR, and fluorescence spectra have been used to characterize and compare the structural

  17. Swine Leukocyte Antigen (SLA) Class II is a Xenoantigen. (United States)

    Ladowski, Joseph M; Reyes, Luz M; Martens, Gregory R; Butler, James R; Wang, Zheng-Yu; Eckhoff, Devin E; Tector, Matt; Tector, A Joseph


    Over 130 000 patients in the United States alone need a life-saving organ transplant. Genetically modified porcine organs could resolve the donor organ shortage, but human xenoreactive antibodies destroy pig cells and are the major barrier to clinical application of xenotransplantation. The objective of this study was to determine whether waitlisted patients possess preformed antibodies to swine leukocyte antigen (SLA) class II, homologs of the class II human leukocyte antigens (HLA). Sera from people currently awaiting solid organ transplant were tested for IgG binding to class II SLA proteins when expressed on mammalian cells. Pig fibroblasts were made positive by transfection with the class II transactivator (CIITA). As a second expression system, transgenes encoding the alpha and beta chains of class II SLA were transfected into Human embryonic kidney (HEK293) cells. Human sera containing IgG specific for class II HLA molecules exhibited greater binding to class II SLA positive cells than to SLA negative cells. Sera lacking antibodies against class II HLA showed no change in binding regardless of the presence of class II SLA. These antibodies could recognize either SLA-DR or SLA-DQ complexes. Class II SLA proteins may behave as xenoantigens for people with humoral immunity towards class II HLA molecules.

  4. Analysis of the Characteristics of Discussion Materials that Promote Group Discussion in the Medical Humanities. (United States)

    Ahn, Jae Hee; Jeon, Woo Taek


    This study aims to analyze the characteristics of discussion materials that promote student participation in discussions, satisfaction with student instruction, and tutor intervention in the medical humanities. We surveyed 117 premedical students and 7 tutors who attended 4-week group discussions in the medical humanities in 2010. We described the discussion materials using the following 4 characteristics as independent variables: material type, level of understanding, interest, and quantity. Dependent variables were: student participation in the discussion, student instruction satisfaction, and tutor intervention. Correlation analysis, multiple regression analysis, and crosstab were performed using SPSS 15.0. The correlation between the characteristics of the discussion materials differed by grade. When the books were chosen as the discussion material in the instruction of first-year premedical students, the correlation between level of understanding, interest, and quantity was negative. Higher levels of understanding of the material and interest in the material led to an increase in discussion participation among both first- and second-year premedical students. Higher levels of understanding and interest of the discussion material also increased student satisfaction with the instruction, regardless of grade. Finally, levels of understanding of the material affected the degree of tutor intervention. Tutors intervened more often in discussions with first-year premedical students than with second-year premedical students. Differences in grades and the understanding of the discussion material should be considered when choosing discussion materials. Further study is required to continue the development of the discussion model and improve methods of facilitate discussion among students in the medical humanities.

  6. Spectroscopic and thermal degradation behavior of Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) complexes with thiopental sodium anesthesia drug (United States)

    Refat, Moamen S.


    A new series of Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) complexes have been synthesized with thiopental sodium anesthesia drug. The elemental analyses of the complexes are confined to stoichiometry of the formulas [M(TPL)3]ṡnH2O (M = Cr(III) or Fe(III); n = 6 or 5), [M(TPL)2(H2O)2]ṡnH2O (M = Mn(II), Co(II) or Ni(II); n = 0 or 4), and [M(TPL)2] (M = Cu(II) or Zn(II); n = 2 or 0) respectively, where TPL is thiopental chelating agent. Structures have been discussed and suggested upon elemental analyses, infrared, Raman, electronic, electron spin resonance, 1H NMR spectral data and magnetic studies. The X-ray powder diffraction (XRD) was performed of metal complexes. The XRD patterns indicate crystalline nature for the complexes. The measured low molar conductance values in dimethylsulfoxide indicate that the complexes are non-electrolyte nature. Spectroscopic discussion refer that coordination take place through three types: Cdbnd N (pyrimidine moiety) nitrogen and C2sbnd S (2-thiolate group) for Cr(III), Mn(II) and Fe(III), C6dbnd O (amido group) oxygen and C2sbnd S (2-thiolate group) for Co(II) and Ni(II), and Cu(II) and Zn(II) ions coordinated via Cdbnd N (pyrimidine moiety) nitrogen, C2dbnd S (2-thiolate group) and C6dbnd O (amido group) oxygen, respectively. The thermal behavior (TG/DTG/DTA) of the complexes was studied and kinetic parameters were determined by Horowitz-Metzger and Coats-Redfern methods. The thiopental and its complexes have been screened for their antimicrobial (G+ and G-) bacteria (Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Pseudomonas aeruginosa) and fungi (Aspergillus flavus and Candida albicans) activities by minimum inhibitory concentration (MIC) method.

  7. Infrared [Fe II] Emission Lines from Radiative Atomic Shocks

    CERN Document Server

    Koo, Bon-Chul; Kim, Hyun-Jeong


    [Fe II] emission lines are prominent in the infrared (IR), and they are important diagnostic tools for radiative atomic shocks. We investigate the emission characteristics of [Fe II] lines using a shock code developed by Raymond (1979) with updated atomic parameters. We first review general characteristics of IR [Fe II] emission lines from shocked gas, and derive [Fe II] line fluxes as a function of shock speed and ambient density. We have compiled the available IR [Fe II] line observations of interstellar shocks and compare them to the ratios predicted from our model. The sample includes both young and old supernova remnants in the Galaxy and the Large Magellanic Cloud and several Herbig-Haro objects. We find that the observed ratios of IR [Fe II] lines generally fall on our grid of shock models, but the ratios of some mid-infrared lines, e.g., [Fe II] 35.35 um/[Fe II] 25.99 um, [Fe II] 5.340 um/[Fe II] 25.99 um, and [Fe II] 5.340 um/[Fe II] 17.94 um, are significantly offset from our model grid.

  8. Exploring the institutional logics of health professions education scholarship units. (United States)

    Varpio, Lara; O'Brien, Bridget; Hu, Wendy; Ten Cate, Olle; Durning, Steven J; van der Vleuten, Cees; Gruppen, Larry; Irby, David; Humphrey-Murto, Susan; Hamstra, Stanley J


    Although health professions education scholarship units (HPESUs) share a commitment to the production and dissemination of rigorous educational practices and research, they are situated in many different contexts and have a wide range of structures and functions. In this study, the authors explore the institutional logics common across HPESUs, and how these logics influence the organisation and activities of HPESUs. The authors analysed interviews with HPESU leaders in Canada (n = 12), Australia (n = 21), New Zealand (n = 3) and the USA (n = 11). Using an iterative process, they engaged in inductive and deductive analyses to identify institutional logics across all participating HPESUs. They explored the contextual factors that influence how these institutional logics impact each HPESU's structure and function. Participants identified three institutional logics influencing the organisational structure and functions of an HPESU: (i) the logic of financial accountability; (ii) the logic of a cohesive education continuum, and (iii) the logic of academic research, service and teaching. Although most HPESUs embodied all three logics, the power of the logics varied among units. The relative power of each logic influenced leaders' decisions about how members of the unit allocate their time, and what kinds of scholarly contribution and product are valued by the HPESU. Identifying the configuration of these three logics within and across HPESUs provides insights into the reasons why individual units are structured and function in particular ways. Having a common language in which to discuss these logics can enhance transparency, facilitate evaluation, and help leaders select appropriate indicators of HPESU success. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

  9. How to write a discussion section? (United States)

    Şanlı, Öner; Erdem, Selçuk; Tefik, Tzevat


    Writing manuscripts to describe study outcomes, although not easy, is the main task of an academician. The aim of the present review is to outline the main aspects of writing the discussion section of a manuscript. Additionally, we address various issues regarding manuscripts in general. It is advisable to work on a manuscript regularly to avoid losing familiarity with the article. On principle, simple, clear and effective language should be used throughout the text. In addition, a pre-peer review process is recommended to obtain feedback on the manuscript. The discussion section can be written in 3 parts: an introductory paragraph, intermediate paragraphs and a conclusion paragraph. For intermediate paragraphs, a "divide and conquer" approach, meaning a full paragraph describing each of the study endpoints, can be used. In conclusion, academic writing is similar to other skills, and practice makes perfect.

  12. Quantum clock: A critical discussion on spacetime

    CERN Document Server

    Burderi, Luciano; Iaria, Rosario


    We critically discuss the measure of very short time intervals. By means of a Gedankenexperiment, we describe an ideal clock based on the occurrence of completely random events. Many previous thought experiments have suggested fundamental Planck-scale limits on measurements of distance and time. Here we present a new type of thought experiment, based on a different type of clock, that provide further support for the existence of such limits. We show that the minimum time interval $\\Delta t$ that this clock can measure scales as the inverse of its size $\\Delta r$. This implies an uncertainty relation between space and time: $\\Delta r$ $\\Delta t$ $> G \\hbar / c^4$; where G, $\\hbar$ and c are the gravitational constant, the reduced Planck constant, and the speed of light, respectively. We outline and briefly discuss the implications of this uncertainty conjecture.

  13. Restorative culture in school. Continuation of discussion

    Directory of Open Access Journals (Sweden)

    A.A. Pentin


    Full Text Available The article deals with the lack of effective ways of building relationships, parenting responsibility and conflict solving in the school community. It is addressed to the whole school community – to the administration, psychologists and social workers, to the faculty, parents and students. We discuss the key concepts and principles of “restorative culture” and the reasons for its introduction in educational institutions. The restorative culture refers to activities on formation and spread of interpersonal relations value in the aspect of its understanding, trust, acceptance of active responsibility, separation of problems and subjects, and focus on the successful experience. We briefly discuss the theory of restorative justice and narrative practice. Particular attention is paid to the typical methods of school response to conflicts, and to zero-tolerance policy. We propose that the school community needs a number of specific technologies that would optimally suit for different types of situations and would constitute a part of the system

  20. Islamophobia? The German Discussion about Islamophobia

    Directory of Open Access Journals (Sweden)

    Astrid Bötticher


    Full Text Available Islamophobia is a term which is relatively new in the world of social science; it is a neologism. Kofi Annan has warned about it but there is not a clear, undoubted concept to it yet – and it is questionable if there ever will be, especially if one looks into the German controversy about the term. The German discussion is not unique though, and must fall into the pattern of wider, European discussion about the Islamic minority. Prominent figures of Islamic hatred in Europe are for instance Oriana Fallaci and Brigitte Bardot. Against them, there stands a more liberal community that does not want to follow the language of violence and hatred. Two different standpoints are the main poles of discussion. One group wants to use Islamophobia as a concept, the other group opposes the term. In between, there is the scientific concept of Islamophobia that is threatened to be pulverized before it is even fully conceptualized. In the middle position there are also intellectuals known as Islamic reformers who argue that Islamophobia should be replaced by the term Islam-critique.

  5. Neurosurgical notes: World War II. (United States)

    Pool, J L


    This concerns my activities as a neurosurgeon in the European Theater of Operations and the North African, Tunisian campaign, during World War II. Action during the Battle of the Bulge came later. Our mobile tent hospital, the 9th Evacuation Hospital, was similar to that depicted in the television show M*A*S*H. To lend flavor to these comments, I have referred to medical and surgical matters in other units as well as our own, mentioned global aspects of the war, and included vignettes of life off-duty. The story begins after induction into the Army Medical Corps as a volunteer in July 1942 and ends with honorable discharge in April 1946.

    Full Text Available The structure of the title compound, [CoII(C2H8N23]SO4, the cobalt example of [M(C2H8N23]SO4, is reported. The Co and S atoms are located at the 2d and 2c Wyckoff sites (point symmetry 32, respectively. The Co atom is coordinated by six N atoms of three chelating ethylenediamine molecules generated from half of the ethylenediamine molecule in the asymmetric unit. The O atoms of the sulfate anion are disordered mostly over two crystallographic sites. The third disorder site of O (site symmetry 3 has a site occupancy approaching zero. The H atoms of the ethylenediamine molecules interact with the sulfate anions via intermolecular N—H...O hydrogen-bonding interactions.

  7. Biologically active new Fe(II, Co(II, Ni(II, Cu(II, Zn(II and Cd(II complexes of N-(2-thienylmethylenemethanamine

    Directory of Open Access Journals (Sweden)

    C. SPÎNU


    Full Text Available Iron(II, cobalt(II, nickel (II, copper (II, zinc(II and cadmium(II complexes of the type ML2Cl2, where M is a metal and L is the Schiff base N-(2-thienylmethylenemethanamine (TNAM formed by the condensation of 2-thiophenecarboxaldehyde and methylamine, were prepared and characterized by elemental analysis as well as magnetic and spectroscopic measurements. The elemental analyses suggest the stoichiometry to be 1:2 (metal:ligand. Magnetic susceptibility data coupled with electronic, ESR and Mössbauer spectra suggest a distorted octahedral structure for the Fe(II, Co(II and Ni(II complexes, a square-planar geometry for the Cu(II compound and a tetrahedral geometry for the Zn(II and Cd(II complexes. The infrared and NMR spectra of the complexes agree with co-ordination to the central metal atom through nitrogen and sulphur atoms. Conductance measurements suggest the non-electrolytic nature of the complexes, except for the Cu(II, Zn(II and Cd(II complexes, which are 1:2 electrolytes. The Schiff base and its metal chelates were screened for their biological activity against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa and the metal chelates were found to possess better antibacterial activity than that of the uncomplexed Schiff base.

    CERN Document Server

    Carminati, Federico; Riemann, Tord


    Round table discussions are in the tradition of ACAT. This year's plenary round table discussion was devoted to questions related to the use of scientific software in High Energy Physics and beyond. The 90 minutes of discussion were lively, and quite a lot of diverse opinions were spelled out. Although the discussion was, in part, controversial, the participants agreed unanimously on several basic issues in software sharing: (i) The importance of having various licensing models in academic research; (ii) The basic value of proper recognition and attribution of intellectual property, including scientific software; (iii) The user respect for the conditions of use, including licence statements, as formulated by the author. The need of a similar discussion on the issues of data sharing was emphasized and it was recommended to cover this subject at the conference round table discussion of next ACAT. In this contribution, we summarise selected topics that were covered in the introductory talks and in the following ...

  9. Using Technology to Support Discussions on Sensitive Topics in the Study of Business Ethics

    Directory of Open Access Journals (Sweden)

    Michelle WL Fong


    Full Text Available There is a dearth of research into teaching strategies and learning approaches for units involving sensitive topics that can provoke an emotional response in students. In a business ethics unit, attempts to strike a balance between conceptual knowledge and theory and skills training can be challenging because the unit can involve personal, sensitive or controversial topics. When engaging in deep and meaningful face-to-face discussion, students may unknowingly divulge personal opinions that they later regret or become identified with by other students over time. Value-laden topics may also lead to clashes between students if face-to-face discussions are not managed properly. This paper considers the use of technology in blended learning to provide an optimal learning environment for student discussion on sensitive topics via role-play and simulation in a first-year business ethics unit. The Audience Response System (ARS, online discussion boards and blogs, and wikis are assessed for their suitability in supporting online role-play and simulation. Among these online tools, asynchronous online discussion boards and blogs are the ideal tools for supporting student discussion on sensitive topics in online role-play and simulation.

  10. Regulation of MHC Class II-Peptide Complex Expression by Ubiquitination

    Directory of Open Access Journals (Sweden)

    Kyung Jin eCho


    Full Text Available MHC class II (MHC-II molecules are present on antigen presenting cells (APCs and these molecules function by binding antigenic peptides and presenting these peptides to antigen-specific CD4+ T cells. APCs continuously generate and degrade MHC-II molecules, and ubiquitination of MHC-II has recently been shown to be a key regulator of MHC-II expression in dendritic cells (DCs. In this mini-review we will examine the mechanism by which the E3 ubiquitin ligase March-I regulates MHC-II expression on APCs and will discuss the functional consequences of altering MHC-II ubiquitination.

  11. Making Theory I. Producing Physics And Physicists In Postwar America. Ii. Post-inflation Reheating In An Expanding Universe

    CERN Document Server

    Kaiser, D I


    This dissertation examines the reinvention of theoretical physics in the United States through pedagogical means after World War II. Physics graduate student enrollments ballooned immediately after the war. The unprecedented enrollments forced questions of procedures and standards for graduate training as never before. At the same time, the crush of numbers spurred an increased bureaucratization and, at least some American physicists feared, a different system of values than what had prevailed during the quieter interwar period. Out of these new bureaucratic and pedagogical developments, theoretical physics became a recognized specialty within American physics, surrounded by new ideas about what theory was for and how students should be trained to do it. Two case studies focus on developments within theoretical physics after the war, using pedagogy as a lens through which to understand the links between practices and practitioners. Within nuclear and particle physics, as Part II discusses, young graduate stud...

  17. Nanotherapeutics--product development along the "nanomaterial" discussion. (United States)

    Wacker, Matthias G


    Nanomaterials have become part of formulation development in the pharmaceutical industry and offer exciting opportunities in the area of targeted drug delivery. But they may also exert unexpected toxicities and potentially pose a threat to human health and the environment. Since the Scientific Committee on Emerging and Newly Identified Health Risks recommended a definition of "nanomaterials" for implementation into the existing and upcoming regulatory framework in the European Union, a discussion about safety requirements of new nanoscale products has emerged. At the same time, the Food and Drug Administration of the United States still observes recent developments in this area. Although the impact on the pharmaceutical product chain is still uncertain, guidelines on risk assessment in food products and cosmetics are available and offer a preview of future developments in the regimens of pharmaceuticals.

Constructive comments and suggestions by readers of the Minerals Yearbook are welcomed.

  19. Diversity: How to Begin the Discussion

    Directory of Open Access Journals (Sweden)

    Brenda Alston-Mills


    Full Text Available The perception of diversity and inclusion, as it relates to social justice, often evokes destructive responses, either spoken or unspoken. It is one of the ‘malicious problems’ found in the classroom, the workplace, and amongst other parts of our society. In challenging these problems with diversity and inclusion, conversations regarding the substantive aspects of oppression and inequitable distribution of power of one group over another must be initiated to educate or expand the thinking of our modern day society. Formulating solutions from these conversations, willing individuals must be able to name the issue, analyze its impact, and enact a positive change, while acknowledging the difficulties in creating conversations of an issue that is in dire need of revelation. This report provides a non-controversial presentation, beginning with reasons for resistance, followed by survival strategies, and ending with pro-active strategies to establish dialogue and to allow for personal stories. Further discussion will analyze aggressive behavior, examine critical core values for an individual and organization, discuss positive and effective methods for combating mistreatment, and empowerment strategies to respond positively to oppression. Strategies for engaging an organization are included, such as how to use these tools to co-create a vision for a welcoming environment in organizations, while acknowledging the uncomfortable atmosphere that surrounds the topic of cultural change. Accepting that this uncomfortable environment stems from fear itself, fear is a viable part of the process towards trust and resolution.

  20. Disgust discussed: introduction to the special section. (United States)

    Pole, Nnamdi


    The author introduces a special section of Psychological Bulletin devoted to the study of disgust. After discussing conflicts between its supposed role as a basic emotion and its more recently understood involvement in responding to moral transgressions, the author summarizes 3 articles contained in the special section. Widen and Russell (2013) present a developmental account of disgust highlighting the ages at which children experience, express, understand, verbalize, and recognize disgust. The article shows that disgust is present early but that recognition of disgust in others is considerably delayed. Chapman and Anderson (2013) review evidence pertaining to the question of whether genuine disgust is elicited by moral transgressions. Their review covers data from self-report, brain imaging, facial behavior, and implicit measures gathered from both experimental and correlational studies. They conclude that moral transgressions elicit genuine disgust. Russell and Giner-Sorolla (2013) ask what types of moral transgressions are most likely to elicit pure disgust. They find that moral transgressions involving body violations are more likely than others to elicit such disgust. Moreover, they suggest that disgust elicited by body violations is likely to be more resistant to modification by context, situation, and efforts at rationalization. Taken together, the reviews support the view that rudiments of disgust to physical objects are present early in life but later become adapted to social influence and new moral purposes. Social implications are discussed. © 2013 American Psychological Association
