Full Text Available For the public institutions, social networks represent a communication channel completing what represents the professional public communication, so the role of the professional communicator does not end or diminish and neither does the role of traditional mass-media. It is about an evolution, a modification, an adaptation of public communication and not a replacement of the way of achieving such communication. By this study, I proposed myself to identify the way in which the public institutions in Romania have adapted to the new trends imposed to public communication. To this end, I conducted an analysis of the structure, content, presentation and visibility in the online media of the Facebook pages of the 21 ministries composing the Romanian Government. I chose ministries as a subject of this study because, as institutions representing the central public administration of Romania, they exercise their competence at the level of the entire national territory and, generating public policies, have a major impact on the socio-economic environment, addressing a large number of beneficiaries. I noticed that all the ministries have an official Facebook page, these pages are updated and, by the published information, they are constituted as key elements in all representation media for these institutions.

Full Text Available The marketing strategy, as core of the marketing policy, in the contemporary society and in the public institution, becomes a necessity not just a fashion. We undertake to reinforce this statement by arguments and to outline the specificity of the marketing strategy in the public institution of the modern society. Although public institutions are created and supported only if there is a large amount of social needs to be met during a certain period of time, the adoption of adequate marketing strategies and tactics is a must in order to achieve their efficiency.

Antigens in the SC blood group system are expressed by the human erythrocyte membrane-associated protein (ERMAP).Two molecular bases have been reported for the Sc,un phenotype:SC*307del2 and SC*994C>T. We report our investigation of the molecular background of five Sc,n1 individuals from the Pacific Islands and describe the successful transfusion of Sc3+ blood to a patient with anti-Sc3 in her plasma. SC (ERMAP) exons 2,3, and 12 and their flanking intronic regions were analyzed. TheSC*994C>T change introduces a restriction enzyme cleavage site for Tsp45I, and polymerase chain reaction (PCR) products from exon 12 were subjected to this PCR-restriction fragment length polymorphism (RFLP) assay. The five samples had the variant SC*994T/T. One sample, from a first cousin of one Marshallese proband, was heterozygous for SC*1514C/T (in the 3' untranslated region); the other four samples were SC*1514C/C(consensus sequence). Samples from white donors (n = 100) and African American donors (n = 99) were tested using the Tsp45IPCR-RFLP assay; all gave a banding pattern that was consistent with the SC*994C/C consensus sequence. In all five samples,our analyses showed homozygosity for the nonsense nucleotide change SC*994C>Tin an allele carrying the nucleotide associated with SLd. Further investigation determined that one of the probands reported previously with the SC*994C>T change was from the Marshall Islands (which form part of the Micronesian Pacific Islands) and the other was from an unspecified location within the large collection of Pacific Islands. Taken together, the five known probands with the SC*994C>T silencing nucleotide change were from the Pacific Islands.

Full Text Available Public preschool educational institutions in Slovenia are mostly financed by public money, it means bay state and municipalities. They are also financed by parents. So, it is important that preschool institutions are using public money transparent and responsible, for this reason public preschool institution should have internal controls in financing. The internal auditor as independent professional should verify if internal controls works. The purpose of this paper is to investigate how internal controls in financing public educational institution works it means which internal controls are important in financing the preschool institution - on the selected institution to show and check how internal controls work. For this reason we divide internal controls in the financing in two phases: (1 internal controls in the preparation of the annual financial plan and financial planning of financial resources for institution’s programs and activities, (2 internal controls in obtaining financial resources. We used methods of internal auditing and research approaches as sampling, unstructured interviews and analysis of documents. The results showed that selected preschool institution should work on rules of recovery and monitoring of claims. The findings provide useful academic insight to setting internal controls as well as practical guidance for preschool institutions.

Hural, Anastasiya

2011-05-01

Full Text Available BACKGROUND. The main source of state public health institutions financing in Ukraine is budgetary funding. In order to overcome the underfunding, the idea of multichannel health financing was proposed in the late 1990s. The main forms of extrabudgetary financial support of public health institutions in Ukraine are voluntary health insurance, non-profit self-financing, charity and sponsorship. The study aims to deeper understand the nature of alternative financing mechanisms of state public health institutions in Ukraine and peculiarities of their use in practice.METHODS. The proposed study is exploratory. Case-study was selected as research method. Nine unstructured interviews were conducted in six health care facilities that have agreed to participate in the study. All studied facilities were in-patient.RESULTS. The sources of financial revenues of the studied institutions were as follows: reimbursement for treatment of insured patients, reimbursement for treatment of sickness funds members, payments for services (medical examinations, counseling, transportation to the hospital, rental of premises, payment for internship from the students of paid forms of medical education, charitable contributions, contracts with companies, contracts with private clinics based in public institutions’ premises (limited liability companies, private entrepreneurs, sponsorship, grants, gifts, payments for services for foreigners, and in-kind revenues. Major health facilities expenditures were the following: salaries (not covered from extrabudgetary revenues; ranged from 70% to 92% of the funds provided to the institutions from state (municipal, regional budget, energy carriers (partially covered from extrabudgetary funds, patients nutrition, medicines, materials, household expenditures, reparation of premises, and purchase of equipment (mostly covered from extrabudgetary revenues.

Public Participation and Institutional Fit: A Social-Psychological Perspective

Directory of Open Access Journals (Sweden)

Daniel A. DeCaro

2013-12-01

Full Text Available Public participation plays a role in the development and long-term maintenance of environmental institutions that are well-matched to local social-ecological conditions. However, the means by which public participation impacts such institutional fit remains unclear. We argue that one major reason for this lack of clarity is that analysts have not clearly outlined how humankind's sense of agency, or self-determination, influences institutional outcomes. Moreover, the concept of institutional fit is ambiguous as to what constitutes a good fit and how such fit could be diagnosed or improved. This is especially true for "social fit," or how well institutions match human expectations and local behavioral patterns. We develop an interdisciplinary framework based on principles of human agency and institutional analysis from social psychology to address these problems. Using the concept of "institutional acceptance" as an indicator of social fit, we show how analysts can define, diagnose, and improve social fit of participatory programs. We also show how such fit emerges and is sustained over time. This interdisciplinary perspective on fit and participation has important implications for participatory approaches to environmental management and the scientific study of institutional evolution.

Graphical abstract: The experimentally unknown systems ScCN and ScNC have been studied through single reference CISD and CCSD(T) methods. A total of 20 = 10 (ScCN) + 10 (ScNC) states were examined. All states are quite ionic whereas ScNC(X ∼3 Δ) is stabler than ScCN(X ∼3 Δ) by ∼5 kcal/mol. Display Omitted Highlights: ► We have studied through ab initio methods the polytopic system Sc[CN]. ► A series of low lying states for both isomeric forms have been examined. ► Around equilibrium the system displays a pronounced Sc + [CN] − ionic character. - Abstract: We have studied the experimentally unknown Sc[CN] molecular system in both its isomeric forms, scandium cyanide (ScCN) and isocyanide (ScNC), through ab initio computations. We report energetics, geometries, harmonic frequencies, and dipole moments for the first 20 Sc[CN] states correlating diabatically to Sc + ( 3 D, 1 D, 3 F) + CN − (X 1 Σ + ). Both isomers have a pronounced ionic character around equilibrium due to the high electron affinity of the CN group and the low ionization energy of the Sc atom. According to our calculations the ScNC isomer (X ∼3 Δ) is stabler than the ScCN(X ∼3 Δ) by ∼5 kcal/mol.

Full Text Available The authors proceed from the thesis that the interaction between business and government is essential for the development of each state. This paper investigates the institutional framework of public-private partnership (PPP in the Russian Federation. Based on the assessment of regulations functioning in Russia, it is concluded that, despite a number of legislative acts designed to regulate the scope of partnerships between the public and the private sector, due to the limited range of the issues and the lack of essential problems range studied, the question of legislative support to the PPP is not resolved. The role of public institutions in the development of interaction between government and business is shown. Based on the analysis of a large factual material, the institutions of PPP development are evaluated: the Investment Fund of the Russian Federation, state corporations, venture innovation funds and special economic zones. This paper states that for each country and region it is essential to identify the priority sectors of public-private partnership.

to address parts of this void. This study examines the agency exerted by top-level public servants through their everyday strategy and policy work in face of co-existing logics of public administration. The findings illustrate how their action strategies span from more passive strategies of coping...... with coexisting logics of administration to more skilled agency of combining logics aimed at enhancing their opportunity and action space. The study suggests that the interplay between co-existing institutional logics, action strategies and the practical skills of top-level public servants provides the basis...... for both coping and more proactive strategies in pluralistic public administrations. Findings illustrate the role of public servants' practical sense of realizable opportunities that inform such strategies of handling co-existing institutional logics.

2017-12-01

Public schools and youth voices are largely absent from climate resilience planning and projects in New York City. Additionally, research shows that U.S. science teachers' understanding of climate science is lacking, hence there is not only an urgent need to train and support teachers on both the science and pedagogy of climate change, but to link climate literacy, resilience thinking and service learning in K-12 education. However, research on participation of students and teachers in authentic, civic-oriented experiences points to increased engagement and learning outcomes in science. The Resilient Schools Consortium (RiSC) Project will address all these needs through an afterschool program in six coastal Brooklyn schools that engages teachers and urban youth (grades 6-12), in school and community climate resilience assessment and project design. The RiSC climate curriculum, co-designed by New York City school teachers with Brooklyn College, the National Wildlife Federation, New York Sea Grant and the Science and Resilience Institute at Jamaica Bay, will begin by helping students to understand the difference between climate and weather. The curriculum makes extensive use of existing resources such as NOAA's Digital Coast and the Coastal Resilience Mapping Portal. Through a series of four modules over two school years, the six RiSC teams will; 1. explore and understand the human-induced drivers of climate change and, particularly, the significant climate and extreme weather related risks to their schools and surrounding communities; 2. complete a climate vulnerability assessment within the school and the community that is aligned to OneNYC - the city's resilience planning document; 3. design and execute a school-based resilience project; and 4. propose resilience guidelines for NYC Department of Education schools. At the end of each school year, the six RiSC teams will convene a RiSC summit with city officials and resilience practitioners to share ideas and

Highlights: • Two lattice structures of equiatomic Al–Sc compounds are confirmed. • Al–Sc phase at Sc 50 at.% has a space group of Pbam. • Al–Sc phase at Sc 55 at.% has a space group of B2. • B2 AlSc is a metastable phase with Sc 50 at.%. • Lattice transition between two compounds is proposed under local thermal stress. - Abstract: Intermetallic compound AlSc is found in the equiatomic Al–Sc binary alloy. The present work indicates that the orthorhombic AlSc with the Au{sub 2}CuZn-type structure can be formed at 50 at.% Sc, while the CsCl-type (B2) AlSc will be formed at 55 at.% Sc. After annealing at 1100 °C, some orthorhombic AlSc grains transit to the B2 structure, and the annealing at lower temperatures leads to the disappearance of B2 phase, indicating that the B2 AlSc is also a metastable phase in the alloy at lower Sc content (<50 at.%). First-principle calculations at 0 K reveal that the orthorhombic AlSc is more stable than the B2 AlSc with the energy difference between them being 5.4 meV/atom. The fast transition between these two phases, which cannot be interpreted by the mechanism of atomic diffusion, was tentatively analyzed by the volume change based on the calculated atomic positions of these two phases.

Full Text Available The paper presents an approach to evaluation the impact of the level of development of institutional environment on the success of the reforms of public administration. The indicators that characterize the degree of development of the institutional environment, in particular, the level of protection of property rights, the development of political competition, civil society, corruption, and trust in society are shown. Depending on the elements of the political-administrative system, socio-economic features, that determine the trajectories of reforms, showing alternative purposes and characterized some indicators, that characterizing the results of reforms for the OECD-counties. Showing institutional problems is implementing reforms in the transition countries, depending on the elements of the political and administrative systems, and socio-cultural factors that determine the path of reform, showing alternative purposes and characterized by individual indicators characterizing the results of the OECD reform. From the point of view of the classification results, the emphasis is made on quantitative results of the operational type, in particular, the dynamics of the general government expenditure and the level of employment of civil servants in relation to employment in the economy as a whole. Showing institutional problems in the implementation of reforms in the transition countries, in particular the gap of development of the bureaucratic ethos, the weakness of the market environment and the insufficient level of external pressure on the quality of public services. The significance for the success of reform and systemic cultural change within the state apparatus, which affects the quality of citizens' satisfaction with public services is observed. It is noted that the preliminary formalization of the public sector, the formation of Weberian bureaucracy type is essential for successful implementation of the New Public Management.

Snyder, Sandra F.

2011-12-21

This Dose Assessment Guidance (DAG) describes methods to use to determine the Maximally-Exposed Individual (MEI) location and to estimate dose impact to that individual under the U.S. Department of Energy Office of Science (DOE-SC) Pacific Northwest National Laboratory (PNNL) Site Environmental Monitoring Plan (EMP). This guidance applies to public dose from radioactive material releases to the air from PNNL Site operations. This document is an attachment to the Pacific Northwest National Laboratory (PNNL) Environmental Monitoring Plan (EMP) and describes dose assessment guidance for radiological air emissions. The impact of radiological air emissions from the U.S. Department of Energy Office of Science (DOE-SC) PNNL Site is indicated by dose estimates to a maximally exposed member of the public, referred to as the maximally exposed individual (MEI). Reporting requirements associated with dose to members of the public from radiological air emissions are in 40 CFR Part 61.94, WAC 246-247-080, and DOE Order 458.1. The DOE Order and state standards for dose from radioactive air emissions are consistent with U.S. Environmental Protection Agency (EPA) dose standards in 40 CFR 61.92 (i.e., 10 mrem/yr to a MEI). Despite the fact that the current Contract Requirements Document (CRD) for the DOE-SC PNNL Site operations does not include the requirement to meet DOE CRD 458.1, paragraph 2.b, public dose limits, the DOE dose limits would be met when EPA limits are met.

Activities of the center for public information in the ''Kurchatov Institute''

International Nuclear Information System (INIS)

Sukhoruchkin, V.

1993-01-01

The problem of the relations between the nuclear community and the public in the former USSR and Russia arose quite recently, exactly after the Chernobyl accident and after the transition to the democratic social order in the country. Recently the Kurchatov Institute was one of the most classified scientific organization in the country. There was no question of discussing its problems in mass media as well as of visiting its facilities by the public. The Center for Public Information was established in the Institute in 1989, in the time when the tide of the public protests against the development of nuclear power in the USSR was at its zenith. The establishing of our public information service had its two objects: to bring back public confidence to nuclear scientists and to restore the high authority of the Kurchatov Institute in the public opinion; the second one was to favour the creation of the objective attitude in the society concerning the necessity of the development of nuclear power. Our first concern was the journalists. The main concern of our contacts with the public and mass media was to demonstrate and to make them understand that nuclear scientists care the public safety not less than the others do. The specific role of our center and the Kurchatov Institute itself is that we represent the only organization in Russia with the competent stuff experienced in nuclear energy and its safety problems at the same time not submitted to any state bodies responsible for Nuclear Power Plants construction and operation. It gives us the possibility to act as an objective arbiter for the public when discussing the problems of nuclear power development

Italian public health care organizations: specialization, institutional deintegration, and public networks relationships.

Del Vecchio, Mario; De Pietro, Carlo

2011-01-01

The Italian National Health Service (INHS) has undergone profound changes over the past three decades. With establishment of the INHS in 1978--a tax-based public health care system with universal coverage--one of the underlying principles was integration. The recognition of health and health care as requiring integrated answers led to the creation of a single public organization, the Local Health Unit, responsible for the health status of the population of its catchment area. At the beginning of the 1990s, the scenario radically changed. The creation of hospital trusts, the development of quasi-market mechanisms and management control tools, the adoption of a prospective payment system for reimbursing health care providers--all were signs of deintegration and institutional unbundling. Two structural changes have deeply sustained this deintegration: patients' empowerment and the increased possibilities for outsourcing practices. In more recent years, a new reintegration effort has occurred, often led by regional governments and based on institutional cooperation and network relationships. However, the earlier structural changes require innovative approaches and solutions if public health care organizations want to retain their leading role.

The Oregon Public Health Policy Institute (PHPI) was designed to enhance public health policy competencies among state and local health department staff. The Oregon Health Authority funded the College of Public Health and Human Sciences at Oregon State University to develop the PHPI curriculum in 2012 and offer it to participants from 4 state public health programs and 5 local health departments in 2013. The curriculum interspersed short instructional sessions on policy development, implementation, and evaluation with longer hands-on team exercises in which participants applied these skills to policy topics their teams had selected. Panel discussions provided insights from legislators and senior Oregon health experts. Participants reported statistically significant increases in public health policy competencies and high satisfaction with PHPI overall. PMID:26066925

Although hemoglobin SC (HbSC) disease is usually considered less severe than sickle cell anemia (SCA), which includes HbSS and HbS/β(0) -thalassemia genotypes, many patients with HbSC experience severe disease complications, including vaso-occlusive pain, acute chest syndrome, avascular necrosis, retinopathy, and poor quality of life. Fully 20 years after the clinical and laboratory efficacy of hydroxyurea was proven in adult SCA patients, the safety and utility of hydroxyurea treatment for HbSC patients remain unclear. Recent NHLBI evidence-based guidelines highlight this as a critical knowledge gap, noting HbSC accounts for ∼30% of sickle cell patients within the United States. To date, only 5 publications have reported short-term, incomplete, or conflicting laboratory and clinical outcomes of hydroxyurea treatment in a total of 71 adults and children with HbSC. We now report on a cohort of 133 adult and pediatric HbSC patients who received hydroxyurea, typically for recurrent vaso-occlusive pain. Hydroxyurea treatment was associated with a stable hemoglobin concentration; increased fetal hemoglobin (HbF) and mean corpuscular volume (MCV); and reduced white blood cell count (WBC), absolute neutrophil count (ANC), and absolute reticulocyte count (ARC). Reversible cytopenias occurred in 22% of patients, primarily neutropenia and thrombocytopenia. Painful events were reduced with hydroxyurea, more in patients >15 years old. These multicenter data support the safety and potentially salutary effects of hydroxyurea treatment for HbSC disease; however, a multicenter, placebo-controlled, Phase 3 clinical trial is needed to determine if hydroxyurea therapy has efficacy for patients with HbSC disease. © 2015 Wiley Periodicals, Inc.

Full Text Available This study approaches the public organizations and their organizational culture by taking into account the gender factor. More specifically, it will approach women’s presence in the leadership of public organizations, the influence of the public organizational culture in the promotion of women in middle and top management positions, and it will finally identify the defining characteristics of the organizational culture of the institutions led by women in comparison to those led by men. Our study is based on a research conducted in Bistriţa-Năsăud County, Romania, by applying a survey in 12 public organizations. The survey comprises 16 questions, seven of which are open questions; 25 women with different positions in the medium and the top management of public institutions were surveyed. The conclusions of the research confirm the existence of some clear differences in the organizational culture of womenled and respectively, men-led public institutions. At the same time, the study identifies possible causes for the low presence of women in the public top management in contrast to their high presence in the execution positions.

A team led by EngenuitySC has performed education and outreach on development of advanced energy markets that will enable wider use of clean energy technologies. This report details the efforts that have made significant advances to improve the market place through education, outreach, and increased communications between industry members. The project resulted in two self-funded industry clusters known as the Fuel Cell Collaborative and NuHub. This project has focused on building and strengthening the leading clean energy clusters in South Carolina: nuclear energy and fuel cell technologies. For the nuclear industry, a new cluster was developed that is now known as NuHub. This cluster has already engaged over 25 nuclear industry leaders or suppliers, four public sector partners, six community economic development foundations, and nearly ten academic partners in a 175 mile radius between Augusta, Georgia and Charlotte, North Carolina. Our outreach has touched over 2,000 stakeholders through the website alone, not including the public audiences and members of the business community reached through news stories and releases that were distributed to over 620 print and online publications. NuHub has established a formal leadership structure, developed subcommittees to focus on industry issues, instituted educational programs for the workforce, and created an industry funding structure that will sustain the industry cluster and mission. NuHub has participated in a wide-variety of community building and outreach activities since its formation under this grant. In the two years since its creation in 2010, we have initiated efforts focused in four main areas that correlate with the four NuHub subcommittees including: innovation, workforce development, industry engagement, and marketing and communications. NuHub successfully raised over $160,000 in both public and private funding, which has supported work to grow the cluster and engage partners including NuScale, Fluor, and

Differences in the use of outsourcing in public and private institutions providing medical services.

The costs of health care in Poland are continuously increasing. Thus, almost every institution providing medical services aims at their limitation. One of the costs rationalisation methods in the health care sector is outsourcing. The study was conducted in 153 randomly selected institutions providing medical activities. The tool was a questionnaire, available via a web browser. Over 30% of public institutions identified the need for financial savings, as the main reason for outsourcing the cleaning function. Among private institutions, the dominant reason for this is too high maintenance cost of the cleaning staff (less than 40% of responses). The huge number of medical institutions use the services of an external company for laundering. Over 30% of public institutions identified as the most common reason for separation of functions laundering lack of resources to upgrade and modernize facilities. Less than 27% of public institutions indicate too high costs of kitchen staff as the main reason for ordering function of feeding. Another reason is the need for financial savings (22% response rate). Some institutions indicate a desire to focus on key areas (20% of responses) and lack of financial resources to upgrade and modernize the kitchen (20% response rate). Public and private institutions exercise control over the quality and method performed by an external service (71% of public institutions and 59% of private institutions). Private institutions often informally exercise external control (difference confirmed - Fisher's exact test). Less than 90% of public institutions indicated satisfaction with the services provided by external companies. The adaptation of outsourcing in medical facilities leads to financial efficiency improvement. Through the separation of some medical functions and entrusting their realisation to external companies, medical institutions can focus on their basic activity that is the provision of health services.

1976-01-01

The acute toxicity, differential distribution in tissue, and elimination of ScCl 3 , 46 ScCl 3 , Sc-EDTA and 46 Sc-EDTA, in mice, has been investigated. The LD 50 sup(24hr) doses for ScCl 3 were 440 and 24 mg kg -1 respectively after intraperitioneal and intravenous injection, and 720 and 108 mg kg -1 respectively for Sc-EDTA. 46 ScCl 3 was extensively deposited in the liver and the spleen. 46 Sc-EDTA was rapidly taken up by the kidney with subsequent elimation via the urine. While-body desaturation kinetics for 46 Sc-EDTA were found to fit a three compartmental model. The fast elimination phase (T1/2 = 12.75 min; K = 0.05540 min -1 ) accounted for 74.6% of the dose; the intermediate phase (T1/2 = 40.2 min; K = 0.01722 min -1 ) for 21.8%, and the slow (T1/2 = 5351 min; K = 0.00013 min -1 ) for 3.6% of the dose.

Nuclear magnetic resonances were measured for {sup 48}Sc and {sup 44m}Sc oriented at 8 mK in an Fe host metal. The magnetic hyperfine splitting frequencies at an external magnetic field of 0.2 T were determined to be 63.22(11) MHz and 64.81(1) MHz for {sup 48}Sc and {sup 44m}Sc, respectively. With the known magnetic moment of {mu}({sup 44m}Sc)=+3.88 (1) {mu}{sub N}, the magnetic moment of {sup 48}Sc is deduced as {mu}({sup 44}Sc)=+3.785(12) {mu}{sub N}. The measured magnetic moment of {sup 48}Sc is discussed in terms of the shell model using the effective interactions.

PUBLIC AND PRIVATE HIGHER EDUCATION INSTITUTIONS IN MALAYSIA: COMPETING, COMPLEMENTARY OR CROSSBREEDS AS EDUCATION PROVIDERS

Directory of Open Access Journals (Sweden)

Wan Chang Da

2007-01-01

Full Text Available Delivery of higher education used to be exclusive to the public sector in Malaysia. However, legislative changes made in 1996 led to the coexistence of public and private higher education institutions. In 2007, there were 20 public universities compared to more than 500 private institutions, of which 30 are currently categorised as universities or university colleges. Looking at their respective roles as higher education providers, public and private institutions display characteristics of being substitutes while at the same time serving complementary roles to one another. This dichotomy between public and private higher education institutions can, in fact, be seen as inclining towards a hybrid model that allows both to operate within a single system of higher education provision in the country. Such a hybrid model is evident in how the clientele is being divided between public and private higher institutions. It is also evident in the different roles played by the respective faculty members as well as in the programmes being made available in either type of institutions.

The novel oxide defect fluorite phase ScTiO(3.5) is formed during the topotactic oxidation of ScTiO(3) bixbyite. We report the oxidation pathway of ScTiO(3) and structure evolution of ScTiO(3.5), Sc(4)Ti(3)O(12), and related scandium-deficient phases as well as high-temperature phase transitions between room temperature and 1300 °Cusing in-situ X-ray diffraction. We provide the first detailed powder neutron diffraction study for ScTiO(3). ScTiO(3) crystallizes in the cubic bixbyite structure in space group Ia3 (206) with a = 9.7099(4) Å. The topotactic oxidation product ScTiO(3.5) crystallizes in an oxide defect fluorite structure in space group Fm3m (225) with a = 4.89199(5) Å. Thermogravimetric and differential thermal analysis experiments combined with in-situ X-ray powder diffraction studies illustrate a complex sequence of a topotactic oxidation pathway, phase segregation, and ion ordering at high temperatures. The optimized bulk synthesis for phase pure ScTiO(3.5) is presented. In contrast to the vanadium-based defect fluorite phases AVO(3.5+x) (A = Sc, In) the novel titanium analogue ScTiO(3.5) is stable over a wide temperature range. Above 950 °C ScTiO(3.5) undergoes decomposition with the final products being Sc(4)Ti(3)O(12) and TiO(2). Simultaneous Rietveld refinements against powder X-ray and neutron diffraction data showed that Sc(4)Ti(3)O(12) also exists in the defect fluorite structure in space group Fm3m (225) with a = 4.90077(4) Å. Sc(4)Ti(3)O(12) undergoes partial reduction in CO/Ar atmosphere to form Sc(4)Ti(3)O(11.69(2)).

Systematic reviews and meta-analyses of test accuracy studies are increasingly being recognised as central in guiding clinical practice. However, there is currently no dedicated and comprehensive software for meta-analysis of diagnostic data. In this article, we present Meta-DiSc, a Windows-based, user-friendly, freely available (for academic use) software that we have developed, piloted, and validated to perform diagnostic meta-analysis. Meta-DiSc a) allows exploration of heterogeneity, with a variety of statistics including chi-square, I-squared and Spearman correlation tests, b) implements meta-regression techniques to explore the relationships between study characteristics and accuracy estimates, c) performs statistical pooling of sensitivities, specificities, likelihood ratios and diagnostic odds ratios using fixed and random effects models, both overall and in subgroups and d) produces high quality figures, including forest plots and summary receiver operating characteristic curves that can be exported for use in manuscripts for publication. All computational algorithms have been validated through comparison with different statistical tools and published meta-analyses. Meta-DiSc has a Graphical User Interface with roll-down menus, dialog boxes, and online help facilities. Meta-DiSc is a comprehensive and dedicated test accuracy meta-analysis software. It has already been used and cited in several meta-analyses published in high-ranking journals. The software is publicly available at http://www.hrc.es/investigacion/metadisc_en.htm.

International financial institutions and human rights: implications for public health.

Science.gov (United States)

Stubbs, Thomas; Kentikelenis, Alexander

2017-01-01

Serving as lender of last resort to countries experiencing unsustainable levels of public debt, international financial institutions have attracted intense controversy over the past decades, exemplified most recently by the popular discontent expressed in Eurozone countries following several rounds of austerity measures. In exchange for access to financial assistance, borrowing countries must settle on a list of often painful policy reforms that are aimed at balancing the budget. This practice has afforded international financial institutions substantial policy influence on governments throughout the world and in a wide array of policy areas of direct bearing on human rights. This article reviews the consequences of policy reforms mandated by international financial institutions on the enjoyment of human rights, focusing on the International Monetary Fund and World Bank. It finds that these reforms undermine the enjoyment of health rights, labour rights, and civil and political rights, all of which have deleterious implications for public health. The evidence suggests that for human rights commitments to be met, a fundamental reorientation of international financial institutions' activities will be necessary.

Elena S. Averkieva

2017-03-01

Full Text Available The interaction system of national public and private sectors institutions is becoming increasingly important in the conditions that characterize the current stage of economic development (such as globalization and post-industrialization trends, geopolitical threats, transformation of production and financial processes. Instability and the dependence of national economies from external environment factors, exposure to systemic crises increase the vulnerability of national business and require the state institutions’ activation in order to support and promote national business initiatives. In these circumstances, one of the most adequate to modern realities forms of entrepreneurial activity stimulation is the public-private partnership model, which proved to be highly effective, both in foreign countries and in Russia. The author reveals potential of public-private partnership as an institution to stimulate entrepreneurial activity by analyzing features of its organizational and management mechanism in the Russian Federation. The practical aspects of the introduction of the public-private partnership model are studied on the example of the Rostov region. The author shows that the implemented programs to encourage entrepreneurship through PPP projects have a positive effect, but at the same time remain a number of problems in the development of the business sector in Russia. The improving ways of the interaction mechanism between government and business at the regional level are identified based on the assessing results of the PPP level in Russia as a whole and in separate regions, implemented by the Association "Center for PPP development".

The effect of Sc additions on the microstructure and age hardening behaviour of as cast Al–Sc alloys

International Nuclear Information System (INIS)

Costa, S.; Puga, H.; Barbosa, J.; Pinto, A.M.P.

2012-01-01

Highlights: ► The Sc effect on the microstructure and ageing behaviour of Al–Sc alloys is studied. ► Cast into copper mould allows the elimination of solution heat treatment. ► Directly aged as cast alloys exhibits higher hardness and precipitation kinetics. ► Sc addition and optimised ageing result in an increase in Al–Sc mechanical properties. -- Abstract: The grain refinement effect and the ageing behaviour of Al–0.5 wt.% Sc, Al–0.7 wt.% Sc, and Al–1 wt.% Sc alloys are studied on the basis of optic microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD) observations and hardness measurements. In Al–Sc alloys the higher grain refinement is observed for Sc contents greater than 0.5 wt.% accompanied by a notorious morphology modification, from coarse columnar grains to a fine perfect equiaxed structure. The as cast structures are characterised by a rich supersaturated solid solution in Sc, that promotes a great age hardening response at 250 °C and 300 °C. The age hardening curves also demonstrate a low overageing kinetics for all the alloys. Although the higher Sc content in solid solution for the alloys with 0.7 and 1 wt.% Sc, the age hardening response of all the Al–Sc alloys remains similar. The direct age hardening response of the as cast Al–0.5 wt.% Sc is shown to be greater than the solutionised and age hardened alloy.

Full Text Available Abstract Background Public-private partnerships (PPPs are potential instruments to enable private collaboration in the health sector. Despite theoretical debate, empirical analyses have thus far tended to focus on the contractual or project dimension, overlooking institutional PPPs, i.e., formal legal entities run by proper corporate-governance mechanisms and jointly owned by public and private parties for the provision of public-health goods. This work aims to fill this gap by carrying out a comparative analysis of the reasons for the adoption of institutional PPPs and the governance and managerial features necessary to establish them as appropriate arrangements for public-health services provisions. Methods A qualitative analysis is carried out on experiences of institutional PPPs within the Italian National Health Service (Sistema Sanitario Nazionale, SSN. The research question is addressed through a contextual and comparative embedded case study design, assuming the entire population of PPPs (4 currently in force in one Italian region as the unit of analysis: (i a rehabilitation hospital, (ii, an orthopaedic-centre, (iii a primary care and ambulatory services facility, and (iv a health- and social-care facility.

Ermishina Anna, V.

2015-06-01

Full Text Available Since early 2000s a policy of attracting private operators to public utilities, which should help to increase productivity, reduce costs, and as a result, reduce utility prices takes place in Russia. The aim of the study is to identify the relationship between institutional arrangements and pricing for water and wastewater services. Applying statistical and cluster analysis to empirical data on water utilities in 13 largest cities has revealed the differences in the level and dynamics of prices for water and wastewater services in the group of public utilities and public private water utilities. In 2011-2014 the level and growth price rates in the group of public private partnerships were higher than in group of municipal water utilities. Thus, the involvement of private operators has not yet lead to the expected reduction in prices.

Overcoming Barriers to Public Engagement through a Multi-Institution Consortium

Science.gov (United States)

Lambert, K. F.; Weiss, M.; Garlick, S.

2016-12-01

A growing body of evidence suggests that public engagement with science (PES) can enhance the relevance and impact of science on society. At the same time, advances in our understanding of public engagement suggest that greater skills, resources, and time horizons are often required to create effective programs. Consequently, despite a proliferation of training programs, many scientists still face the challenge of balancing the demands of public engagement with the requirements of their disciplinary research. Novel institutions are emerging that bring together interdisciplinary networks of principle investigators with PES practitioners to overcome barriers to effective and sustained public engagement in the environmental sciences. We will use the Science Policy Exchange (SPE), a consortium housed at the Harvard Forest, Harvard University, to illustrate how PIs and PES practitioners can collaborate to design public engagement processes, conduct policy-relevant scientific syntheses, and implement science communication strategies. Results from two SPE case studies demonstrate how multi-institutional consortia can help scientists overcome barriers such as lack of knowledge of evidence-based PES approaches, limits on time and funding to implement PES projects, and the need to integrate PES activities with research. The case studies also show how SPE strives to achieve credibility, saliency, and legitimacy in different public policy contexts: (1) engagement between scientists and local stakeholders to develop scenarios of landscape change; and (2) engagement between scientists and policy makers to understand the relationship between power plant emission standards, and air quality, human health and ecosystem function. The presentation will conclude with examples of how SPE programs have led to institutional change (staffing and budget), cultural change (attitudes and expectations of senior leaders), and research change (development of research questions, funding proposals

[Social capital as a determinant of public health].

Bravo Vallejos, N D

The concept of Social Capital (SC), originally described by Durkheim (1893), is composed of dimensions related to cohesion and trust between members of a social group, and considered by the Word Health Organization (WHO) as part of the social determinants of public health for the decrease of inequities and inequalities in health provision. To contribute to the dissemination of the concept of SC related to the social determinants of Public Health, in order to offer the reader in-depth content to observe the potential applications and practices in this field. Literature search (Google Academics™, PubMed, Science direct™, Ebsco Host™). A total of 294 full-text publications were obtained, and those selected were the most influential sources on the evolution and application of the concept of Social Capital, socioeconomic development and health in the last decade. Although the current evidence shows that Social Capital is a determinant related to health, standards are still needed for its measurement. This could allow the concept to be measured, and facilitate its integration into the form of actions that exert positive influence and contribute to the implementation of institutional interventions planned for development and public health.

Advanced solid-state NMR methods and first-principles calculations demonstrate for the first time the formation of penta-coordinated scandium sites. These coordinatively unsaturated sites were shown during the thermal activation of scandium-based metal-organic frameworks (MOFs). A 45 Sc NMR experiment allows their specific observation in activated Sc 3 BTB 2 (H 3 BTB=1,3,5-tris(4-carboxyphenyl)benzene) and MIL-100(Sc) MOFs. The assignment of the ScO 5 groups is supported by the DFT calculations of NMR parameters. The presence of ScO 5 Lewis acid sites in MIL-100(Sc) explains furthermore its catalytic activity. The first NMR experiment to probe 13 C- 45 Sc distances is also introduced. This advanced solid-state NMR pulse sequence allows the demonstration of the shrinkage of the MIL-100(Sc) network when the activation temperature is raised. © 2017 Wiley-VCH Verlag GmbH & Co.

2016-12-01

Full Text Available The aim of this research paper is to compare the quality of education delivered at the undergraduate level in the public and private institutions of the Twin Cities (Islamabad and Rawalpindi in Pakistan. Data is collected with the help of questionnaires from 246 students. The data was collected from three public and three private educational institutions of the Twin Cities, and the age of students ranged from 18 to 27 years. The research instrument used in this paper is the independent sample t-test to find the difference between the three private and three public educational institutions selected in Rawalpindi and Islamabad in terms of different variables that are very important in measuring the quality of education. For analysis, Levene’s test was adopted, which reflects the variations in educational quality with respect to academic staff availability in the twin cities. The differences in close supervision of students by academic staff between public and private sector educational institutions were also analysed, and the results reflected a difference between private and public educational institutions with respect to close supervision of students. The results also highlighted the factors that are involved in higher performance of students in private institutes as compared to that of students in public institutes. These factors can be implemented in the public sector to increase student performance.

Institutional policy learning and public consultation: the Canadian xenotransplantation experience.

Science.gov (United States)

Jones, Mavis; Einsiedel, Edna

2011-09-01

Attempts to evaluate public consultations, participatory technology assessment, and deliberative democracy have typically considered impacts on either policy or participants. The determination of impacts on policy institutions has been limited due to the challenges of tracing effects through the policy process, or penetrating bureaucratic walls. This paper presents findings from a retrospective study exploring the institutional lessons learned from a 2001 Canadian national public consultation on xenotransplantation. The consultation was conducted through an arm's-length process and involved the use of citizen juries in six regional sites. We conducted in-depth interviews of regulatory and policy actors who were engaged in early policy discussions and the consultation process. We reviewed evaluations of this process, both internal and external, which gave us richer insights into what institutional actors saw as the impacts of this consultative experience on their policy environment. Participants in our research identified a broader shift toward openness in policy culture which they linked specifically to the innovative consultation process employed for xenotransplantation. We argue that beyond input into policy decisions, a consultation may have an impact in terms of its contribution to overall shifts in institutional culture (related to institutional learning), such as an "opening" of technological decision processes to a broader range of actors, knowledge, and values.

Disease-related prion protein (PrP(Sc)), which is a structural isoform of the host-encoded cellular prion protein, is thought to be a causative agent of transmissible spongiform encephalopathies. However, the specific role of PrP(Sc) in prion pathogenesis and its relationship to infectivity remain controversial. A time-course study of prion-affected mice was conducted, which showed that the prion infectivity was not simply proportional to the amount of PrP(Sc) in the brain. Centrifugation (20,000 ×g) of the brain homogenate showed that most of the PrP(Sc) was precipitated into the pellet, and the supernatant contained only a slight amount of PrP(Sc). Interestingly, mice inoculated with the obtained supernatant showed incubation periods that were approximately 15 d longer than those of mice inoculated with the crude homogenate even though both inocula contained almost the same infectivity. Our results suggest that a small population of fine PrP(Sc) may be responsible for prion infectivity and that large, aggregated PrP(Sc) may contribute to determining prion disease duration.

SC tuning fork

CERN Document Server

The tuning fork used to modulate the radiofrequency system of the synchro cyclotron (SC) from 1957 to 1973. This piece is an unused spare part. The SC was the 1st accelerator built at CERN. It operated from August 1957 until it was closed down at the end of 1990. In the SC the magnetic field did not change with time, and the particles were accelerated in successive pulses by a radiofrequency voltage of some 20kV which varied in frequency as they spiraled outwards towards the extraction radius. The frequency varied from 30MHz to about 17Mz in each pulse. The tuning fork vibrated at 55MHz in vacuum in an enclosure which formed a variable capacitor in the tuning circuit of the RF system, allowing the RF to vary over the appropriate range to accelerate protons from the centre of the macine up to 600Mev at extraction radius. In operation the tips of the tuning fork blade had an amplitude of movement of over 1 cm. The SC accelerator underwent extensive improvements from 1973 to 1975, including the installation of a...

The sealed cell differential scanning calorimetry (SC-DSC) was sintroduced of commercial blasting explosives. As a series of testing the commercial blasting explosives in performance, an SC-DSC test was made to compare the critical detonability line with that resulting therefrom. From the result of SC-DSC measurement, the critical dilution rate was estimated of commercial blasting explosives to become without detonating propagation. As a result, all the explosives with exception of ANFO one were assumed to have a possibility of detonating propagation so that the ANFO explosive was known to be material, unable to exactly evaluate the detonability by the SC-DSC test. The explosion heat, then calculated by the REITP2 in order to assume how the reaction proceeded in the DSC cell, was compared with the reaction heat measured by the SC-DSC test. As a result, the calculated value was known to be almost equal to or slightly larger than the measured one. 15 refs., 4 figs., 2 tabs.

Three new quaternary scandium vanadium selenium/tellurium oxides, α-ScVSe2O8, β-ScVSe2O8, and ScVTe2O8 have been synthesized through hydrothermal and standard solid-state reactions. Although all three reported materials are stoichiometrically similar, they exhibit different crystal structures: α-ScVSe2O8 has a three-dimensional framework structure consisting of ScO6, VO6, and SeO3 groups. β-ScVSe2O8 reveals another three-dimensional framework composed of ScO7, VO5, and SeO3 polyhedra. ScVTe2O8 shows a layered structure with ScO6, VO4, and TeO4 polyhedra. Interestingly, the constituent cations, that is, Sc(3+), V(5+), Se(4+), and Te(4+) are all in a distorted coordination environment attributable to second-order Jahn-Teller (SOJT) effects. Complete characterizations including infrared spectroscopy, elemental analyses, thermal analyses, dipole moment calculation, and the magnitudes of out-of-center distortions for the compounds are reported. Transformation reactions suggest that α-ScVSe2O8 may change to β-ScVSe2O8, and then to Sc2(SeO3)3·H2O under hydrothermal conditions.

Perceptions on the Effectiveness of Communication between Public Institutions and Journalists through Social Media

Directory of Open Access Journals (Sweden)

Mihaela Păun

2009-11-01

Full Text Available This article presents the challenges and opportunities of social media for public institutions and argues that the designing and implementing government public relations using social media involves more than merely having another communication channel for publics. I will explain the “social media”, the differences between social media and electronic-Public Relations - E-PR, and the communication between public institutions and journalists. The interviews with journalists or with PR specialists in public institutions were focused on the use, the extent of this use, and the perceived value of various social media as sources contributing to agenda building (Cobb, Elder 1983. If journalists are regularly monitoring sites and forums for story ideas and information, it is necessary for PR professionals within each industry to carefully monitor the information placed there and perhaps engage content producers. In this paper, I conclude that social media is an alternative instrument to encourage a two-way communication channel between government and publics. In public relations, the emergence of social media challenges the traditional instruments of government public relations. Responding to the development of information and communication technology (ICT, social media is considered as an alternative communication channel of government public relations efforts.

Single cell transcriptome sequencing (scRNA-Seq) has become a revolutionary tool to study cellular and molecular processes at single cell resolution. Among existing technologies, the recently developed droplet-based platform enables efficient parallel processing of thousands of single cells with direct counting of transcript copies using Unique Molecular Identifier (UMI). Despite the technology advances, statistical methods and computational tools are still lacking for analyzing droplet-based scRNA-Seq data. Particularly, model-based approaches for clustering large-scale single cell transcriptomic data are still under-explored. We developed DIMM-SC, a Dirichlet Mixture Model for clustering droplet-based Single Cell transcriptomic data. This approach explicitly models UMI count data from scRNA-Seq experiments and characterizes variations across different cell clusters via a Dirichlet mixture prior. We performed comprehensive simulations to evaluate DIMM-SC and compared it with existing clustering methods such as K-means, CellTree and Seurat. In addition, we analyzed public scRNA-Seq datasets with known cluster labels and in-house scRNA-Seq datasets from a study of systemic sclerosis with prior biological knowledge to benchmark and validate DIMM-SC. Both simulation studies and real data applications demonstrated that overall, DIMM-SC achieves substantially improved clustering accuracy and much lower clustering variability compared to other existing clustering methods. More importantly, as a model-based approach, DIMM-SC is able to quantify the clustering uncertainty for each single cell, facilitating rigorous statistical inference and biological interpretations, which are typically unavailable from existing clustering methods. DIMM-SC has been implemented in a user-friendly R package with a detailed tutorial available on www.pitt.edu/∼wec47/singlecell.html. wei.chen@chp.edu or hum@ccf.org.

BACKGROUND AND OBJECTIVE. Lithuanian and international public health experts emphasize the importance of leadership in public health. The aim of this study was to explore the self-assessed level of leadership competencies of executives in Lithuanian public health institutions. MATERIAL AND METHODS. Data were collected in a cross-sectional survey of executives of Lithuanian public health institutions in 2010. The total number of returned questionnaires was 55 (response rate, 58.5%). Respondents were asked about their competencies in leadership, teamwork, communication, and conflict management. The evaluation was carried out by analyzing the answers provided in the survey, which used a 5-point rating scale. In addition, the Belbin Team-Role Self-Perception Inventory and the Thomas-Kilmann Conflict Mode Instrument were used. RESULTS. The results showed that respondents were reserved or limited in their individual capacities through this evaluation of their leadership competencies. The mean score was 3.47 (SD, 0.71). Skills in competency areas of communication, teamwork, and conflict management were scored higher (3.73 [SD, 0.67], 3.73 [SD, 0.62], and 3.53 [SD, 0.63], respectively). Most of executives preferred to choose action-oriented roles (76.2%). The most common role was "implementer" (69.1%). "Avoiding" (52.7%) was the most common conflict solving strategy. The results showed that 89.1% of executives wanted to improve teamwork; 83.6%, leadership competencies; 81.8%, communication; and 80.0%, conflict management. CONCLUSIONS. The study results suggest that the executives of Lithuanian public health institutions evaluate their leadership competencies moderately. These results indicate the value of leadership training for public health executives.

THEORETICAL APPROACH ON THE ROLE OF MANAGERIAL COMMUNICATION IN PUBLIC INSTITUTIONS

Directory of Open Access Journals (Sweden)

Sorin PAUN

2014-06-01

Full Text Available The Romanian Government has faced extensive changes in the last period regarding its operating plan, in what was meant to accomplish and the actions of the political representatives and citizens, their tasks and responsibilities. In this paper we have attempted to identify the main factors with direct influence on management of public institutions starting from the communication management. The result of the research showed that leaving aside and not taking into account the strategic perspectives, preparation in terms of poor management of administrative factors are elements that detract from public institutions and from here the lack of initiative and flexibility needed for their operation.

We report on the activities of our NSF PAARE program during Year 3 of the project. Our partnership under this award includes South Carolina State University (a Historically Black College/University), Clemson University (a Ph.D. granting institution) and individual investigators at NASA Ames and elsewhere. Our partnership with the Citizen CATE Experiment and involvement in the total solar eclipse which passed through our campus on August 21, 2017, will be discussed. The PAARE project continues to strengthen our partnership with Clemson. We are close to completing a memorandum of agreement between the two institutions that will allow for the seamless transfer of an undergraduate from SC State to Clemson’s graduate program in physics and astronomy. Additionally, we have worked together under the Citizen CATE project and through other research activities. SC State is a member of the National Astronomy Consortium (NAC) and participates through its faculty and undergraduates, one of whom (Wesley Red) is reporting on his summer internship at this conference. We also served as the state coordinator for South Carolina for the Citizen CATE Experiment. The August 21st path of totality crossed through our campus and the campus of our partner Clemson University. Additional colleges, universities and citizen scientist groups partnered with us to provide 7 sites of coverage across South Carolina from the foothills of the Appalachian mountains to the Atlantic Ocean near the site of departure of the shadow from the continental U.S. Support for this work includes our NSF PAARE award AST-1358913 as well as resources and support provided by Clemson University and the National Optical Astronomy Observatory. CATE work has been supported by NASA SMD award NNX16AB92A to the National Solar Observatory. Additional details can be found at: http://physics.scsu.edu

Scandium fluoride oxoselenate(IV) ScF[SeO3] and scandium oxide oxoselenate(IV) Sc2O2[SeO3] could be synthesized through solid-state reactions. ScF[SeO3] was obtained phase-pure, by reacting mixtures of Sc2O3, ScF3 and SeO2 (molar ratio: 1:1:3) together with CsBr as fluxing agent in corundum crucibles embedded into evacuated glassy silica ampoules after firing at 700 °C for seven days. Sc2O2[SeO3] first emerged as by-product during the attempts to synthesize ScCl[SeO3] following aforementioned synthesis route and could later be reproduced from appropriate Sc2O3/SeO3 mixtures. ScF[SeO3] crystallizes monoclinically in space group P21/m with a=406.43(2), b =661.09(4), c=632.35(4) pm, β=93.298(3)° and Z=2. Sc2O2[SeO3] also crystallizes in the monoclinic system, but in space group P21/n with a=786.02(6), b=527.98(4), c=1086.11(8) pm, β=108.672(3)° for Z=4. The crystal structures of both compounds are strongly influenced by the stereochemically active lone pairs of the ψ1-tetrahedral [SeO3]2- anions. They also show partial structures, where the derivatizing F- or O2- anions play an important role. For ScF[SeO3] chains of the composition 2+∞ 1[FS c 2 / 2 ] form from connected [FSc2]5+ dumbbells, while [OSc3]7+ pyramids and [OSc4]10+ tetrahedra units are condensed to layers according to 2+ ∞ 2[O2Sc2 ] in Sc2O2[SeO3].

Institutional innovation to generate the public acceptance of radioactive waste disposal

International Nuclear Information System (INIS)

Kemp, R.

1991-01-01

Contrasting experiences of public acceptance of radioactive waste disposal are compared for the United Kingdom, France, Sweden and Canada. The disparity between scientifically assessed and publicly perceived levels of risk is noted. The author argues that the form of decision-making process is more important to public acceptance of radioactive waste disposal than the technology of disposal. Public risk perception can be altered by procedures employed in planning, negotiation and consultation. Precisely what constitutes acceptable risk does vary from country to country, and differences in institutional responses and innovation are particularly highlighted. (UK)

Towards a Comprehensive and Up-To-Date Institutional Repository: Development of a Publications Tracking Process

KAUST Repository

Baessa, Mohamed

2016-06-15

As our repository matured we found that a concerted effort was needed to establish it as a resource that institutional stakeholders knew they could turn to for reliable information about the research outputs produced by researchers affiliated with or funded by our institution. The initial impetus for this project was the adoption of an institutional open access policy, which necessitated a process to track the publications of institutional authors, deposit items with applicable open access licenses, and notify authors when an accepted manuscript was needed. To support this process we developed a local publications tracking system independent of our hosted DSpace repository that regularly queries publisher and indexer APIs for new publications, checks for relevant permissions policies, identifies institutional authors and helps us send manuscript request emails. We also harvested records for past items and modified our repository to accommodate metadata-only records. The success of these tracking and harvesting services in making our repository comprehensive and up-to-date has allowed us to rely on our repository as the key source of publications information for additional integrations that update ORCID records with publication information, populate a PlumX metrics dashboard and, most recently, support the implementation of a current research information system (CRIS).

Scandium nitride (ScN) is an emerging indirect bandgap rocksalt semiconductor that has attracted significant attention in recent years for its potential applications in thermoelectric energy conversion devices, as a semiconducting component in epitaxial metal/semiconductor superlattices and as a substrate material for high quality GaN growth. Due to the presence of oxygen impurities and native defects such as nitrogen vacancies, sputter-deposited ScN thin-films are highly degenerate n-type semiconductors with carrier concentrations in the (1-6) × 1020 cm-3 range. In this letter, we show that magnesium nitride (MgxNy) acts as an efficient hole dopant in ScN and reduces the n-type carrier concentration, turning ScN into a p-type semiconductor at high doping levels. Employing a combination of high-resolution X-ray diffraction, transmission electron microscopy, and room temperature optical and temperature dependent electrical measurements, we demonstrate that p-type Sc1-xMgxN thin-film alloys (a) are substitutional solid solutions without MgxNy precipitation, phase segregation, or secondary phase formation within the studied compositional region, (b) exhibit a maximum hole-concentration of 2.2 × 1020 cm-3 and a hole mobility of 21 cm2/Vs, (c) do not show any defect states inside the direct gap of ScN, thus retaining their basic electronic structure, and (d) exhibit alloy scattering dominating hole conduction at high temperatures. These results demonstrate MgxNy doped p-type ScN and compare well with our previous reports on p-type ScN with manganese nitride (MnxNy) doping.

This report summarizes the responses to a mail survey sent to superintendents and other administrators of public school districts. The survey was part of an evaluation project for the USDOE Institutional Conservation Program (ICP). The goal of the project is to identify the most successful energy conservation measures (equipment and activities) available to the institutional buildings sector. To accomplish this goal, four specific research objectives were defined: To determine the impact of the ICP grants program on fostering energy efficiency and saving energy; to determine key characteristics of institutional conservation efforts outside the federal program; To determine the technical, organizational, and Institutional conditions that create the opportunity for energy conservation measures (ECMS) to be most effective; and to identify key technology transfer opportunities. This report focuses on those characteristics of school districts (and the schools within those districts) that might influence the identification, implementation, operation, and impacts of institutional energy conservation efforts. Information about institutional characteristics was gathered through a mail survey of public school districts and private schools. The first mailing resulted in responses from 90 of the 823 public school districts selected through a combination cluster-and-stratification sampling technique and 64 of the 1,700 private schools selected as a stratified random sample. Remaining project resources were used to collect data to achieve a statistically sound sample of a total of 250 public school districts by telephone interviews. In doing so, some questions had to be dropped. Responses from both the mall surveys and the telephone interviews of public school districts were combined into one data set. This report describes results for all 250 districts.

The ScCl 3 + CH 3 CN and ScCl 3 + KNCS + CH 3 CN solutions have been studied by a high-resolution NMR 45 Sc method. It has been estimated that in acetonitrile solutions, with competing ligands of Cl - and NCS - being available, hexacoordination Sc(3) complexes of various compositions are formed, and solvent molecules also take part in formation of the coordination sphere of scandium. Chemical shifts in NMR 45 Sc signals depend linearly on the number of chlor- or NCS - ions bound to scandium(3). This made it possible to determine the value of chemical shifts in signals of all 28 potential complexes formed in a system with three competing ligands

Knowledge insufficient: the management of haemoglobin SC disease.

Pecker, Lydia H; Schaefer, Beverly A; Luchtman-Jones, Lori

2017-02-01

Although haemoglobin SC (HbSC) accounts for 30% of sickle cell disease (SCD) in the United States and United Kingdom, evidence-based guidelines for genotype specific management are lacking. The unique pathology of HbSC disease is complex, characterized by erythrocyte dehydration, intracellular sickling and increased blood viscosity. The evaluation and treatment of patients with HbSC is largely inferred from studies of SCD consisting mostly of haemoglobin SS (HbSS) patients. These studies are underpowered to allow definitive conclusions about HbSC. We review the pathophysiology of HbSC disease, including known and potential differences between HbSS and HbSC, and highlight knowledge gaps in HbSC disease management. Clinical and translational research is needed to develop targeted treatments and to validate management recommendations for efficacy, safety and impact on quality of life for people with HbSC. © 2016 John Wiley & Sons Ltd.

Picking the best publications to showcase graduate courses: Do institutional mechanisms reinforce gender differences?

Previous studies performed by our research group have brought to light the concept “scientific capital” developed by Bourdieu to characterize the vertical segregation framework in Brazilian science, specifically Brazilian graduate programs, which is the main piece of the country’s S&T system. The present study still focuses on gender differences in Brazilian graduate programs but it turns attention to their institutional assignments. Among all information sent annaually to Capes evaluation process, heads of graduate programs have to send the top five publications of the year. Considering the institutional relevance of this set of publications, the present study aims to identify whether an institutional mechanism, as the choice of the best publications of the graduate program by the heads, promotes gender equality or reinforces discrepancies in Brazilian academia. Preliminary results, performed upon official data of teacher-researchers performance affiliated to Federal University of Rio de Janeiro, suggest that males rather than females more are more represented in this selective set of publications.

To achieve faster and equitable improvements in maternal and child health outcomes, the government of India launched the National Rural Health Mission in 2005. This paper describes the equity-enhancing role of the public sector in increasing use of institutional delivery care services in India between 2004 and 2014. Information on 24 661 births from nationally representative survey data for 2004 and 2014 is analysed. Concentration index is computed to describe socioeconomic-rank-related relative inequalities in institutional delivery and decomposition is used to assess the contributions of public and private sectors in overall socioeconomic inequality. Multilevel logistic regression is applied to examine the changes in socioeconomic gradient between 2004 and 2014. The analysis finds that utilization of institutional delivery care in India increased from 43% in 2004 to 83% in 2014. The bulk of the increase was in public sector use (21% in 2004 to 53% in 2014) with a modest increase in private sector use (22% in 2004 to 30% in 2014). The shift from a pro-rich to pro-poor distribution of public sector use is confirmed. Decomposition analysis indicates that 51% of these reductions in socioeconomic inequality are associated with improved pro-poor distribution of public sector births. Multilevel logistic regressions confirm the disappearance of a wealth-based gradient in public sector births between 2004 and 2014. We conclude that public health investments in India have significantly contributed towards an equitable increase in the coverage of institutional delivery care. Sustained policy efforts are necessary, however, with an emphasis on education, sociocultural and geographical factors to ensure universal coverage of institutional delivery care services in India.

Precipitation in cold-rolled Al-Sc-Zr and Al-Mn-Sc-Zr alloys prepared by powder metallurgy

KAUST Repository

Vlach, Martin

2013-12-01

The effects of cold-rolling on thermal, mechanical and electrical properties, microstructure and recrystallization behaviour of the AlScZr and AlMnScZr alloys prepared by powder metallurgy were studied. The powder was produced by atomising in argon with 1% oxygen and then consolidated by hot extrusion at 350 C. The electrical resistometry and microhardness together with differential scanning calorimetry measurements were compared with microstructure development observed by transmission and scanning electron microscopy, X-ray diffraction and electron backscatter diffraction. Fine (sub)grain structure developed and fine coherent Al3Sc and/or Al3(Sc,Zr) particles precipitated during extrusion at 350 C in the alloys studied. Additional precipitation of the Al3Sc and/or Al3(Sc,Zr) particles and/or their coarsening was slightly facilitated by the previous cold rolling. The presence of Sc,Zr-containing particles has a significant antirecrystallization effect that prevents recrystallization at temperatures minimally up to 420 C. The precipitation of the Al6Mn- and/or Al 6(Mn,Fe) particles of a size ~ 1.0 μm at subgrain boundaries has also an essential antirecrystallization effect and totally suppresses recrystallization during 32 h long annealing at 550 C. The texture development of the alloys seems to be affected by high solid solution strengthening by Mn. The precipitation of the Mn-containing alloy is highly enhanced by a cold rolling. The apparent activation energy of the Al3Sc particles formation and/or coarsening and that of the Al6Mn and/or Al 6(Mn,Fe) particle precipitation in the powder and in the compacted alloys were determined. The cold deformation has no effect on the apparent activation energy values of the Al3Sc-phase and the Al 6Mn-phase precipitation. © 2013 Elsevier Inc.

In our quest for materials with specific applications, a theoretical study plays an important role in predicting the properties of compounds. Heusler alloys or compounds are the most studied in this context. More recently, a lot of quaternary Heusler compounds are investigated for potential applications in fields like Spintronics. We report here our preliminary study of the alloys ScMnFeSn and ScFeCoAl, using the ab-initio linear muffin-tin orbital method within the atomic sphere approximation (LMTO-ASA). The alloy ScMnFeSn shows perfect half-metallicity, namely, one of the spins shows a metallic behaviour and the other spin shows semi-conducting behaviour. Such materials find application in devices such as the spin-transfer torque random access memory (STT-MRAM). In addition, the alloy ScMnFeSn is found to have an integral magnetic moment of 4 µB, as predicted by the Slater-Pauling rule. The alloy ScFeCoAl does not show half-metallicity.

Public and Institutional Markets for ESCO Services: ComparingPrograms, Practices and Prformance

2005-03-01

Throughout the U.S. energy services company (ESCO) industry's history, public and institutional sector customers have provided the greatest opportunities for ESCOs to develop projects. Generally speaking, these facilities are large, possess aging infrastructure, and have limited capital budgets for improvements. The convergence of these factors with strong enabling policy support makes performance contracting an attractive and viable option for these customers. Yet despite these shared characteristics and drivers, there is surprising variety of experience among public/institutional customers and projects. This collaborative study examines the public/institutional markets in detail by comparing the overarching models and project performance in the federal government and the ''MUSH'' markets municipal agencies (state/local government), universities/colleges, K-12 schools,and hospitals that have traditionally played host to much of the ESCO industry's activity. Results are drawn from a database of 1634 completed projects held in partnership by the National Association of Energy Services Companies and Lawrence Berkeley National Laboratory (the NAESCO/LBNL database), including 129 federal Super Energy Savings Performance Contracts (ESPC) provided by the Federal Energy Management Program (FEMP) (Strajnic and Nealon 2003). Project data results are supplemented by interviews with ESCOs.

to identify associations between the Burnout domains and the characteristics of the work environment. cross-sectional study with 745 nurses from 40 public health institutions in São Paulo. Nursing Work Index-Revised (NWI-R) and Maslach Burnout Inventory were used. Similar institutions according to NWI-R were grouped by clustering and the Anova and Bonferroni tests were used in the comparative analyzes. there was significant and moderate correlation between emotional exhaustion and autonomy, control over the environment and organizational support; between reduced personal accomplishment, autonomy and organizational support; and between depersonalization and autonomy. The group that presented the worst conditions in the work environment differed on emotional exhaustion from the group with most favorable traits. emotional exhaustion was the trait of Burnout that was more consistently related to the group of institutions with more unfavorable working conditions regarding autonomy, organizational support and control over the environment.

44 Sc is a promising positron emission tomography (PET) radionuclide (T 1/2  = 4.04 hours, E β+average  = 632 keV) and can be made available, using a cyclotron production route, in substantial quantities as a highly pure product. Herein, the authors report on a first-in-human PET/CT study using 44 Sc-DOTATOC prepared with cyclotron-produced 44 Sc. The production of 44 Sc was carried out through the 44 Ca(p,n) 44 Sc nuclear reaction at Paul Scherrer Institut, Switzerland. After separation, 44 Sc was shipped to Zentralklinik Bad Berka, Germany, where radiolabeling was performed, yielding radiochemically pure 44 Sc-DOTATOC. Two patients, currently followed up after peptide receptor radionuclide therapy of metastatic neuroendocrine neoplasms, participated in this proof-of-concept study. Blood sampling was performed before and after application of 44 Sc-DOTATOC. PET/CT acquisitions, performed at different time points after injection of 44 Sc-DOTATOC, allowed detection of even very small lesions on delayed scans. No clinical adverse effects were observed and the laboratory hematological, renal, and hepatic profiles remained unchanged. In this study, cyclotron-produced 44 Sc was used in the clinic for the first time. It is attractive for theranostic application with 177 Lu, 90 Y, or 47 Sc as therapeutic counterparts. 44 Sc-based radiopharmaceuticals will be of particular value for PET facilities without radiopharmacy, to which they can be shipped from a centralized production site.

Full Text Available In Romania, public sector performance is a concept on which it has been written very little and rarely applied in practice. The situation is not the same in developed countries economically to where we focus our attention, regarded as models for our country. Internationally, since the early 70s of the last century there were initiated processes of modernization and reorganization of public institutions in different countries. The society required a higher efficiency of the services provided by it, a better use of public services and also an effective bureaucratic model. It can be said that only in this context, government institutions can gain strength, consistency and can become more reliable. Flexibility, decentralization, creativity, self-management and management contract, all used as measurement tools are the basic features of a managerial reforms that focus on results. Determining the results in the public sector and implementing a system of financial and nonfinancial performance measurement requires a clear definition of the objectives and goals of each organization and component institution.

The colours of Hubble Sc galaxy nuclei

Iskudaryan, S.G.

1975-01-01

The colorimetric data on the nuclei of the Sc galaxies are given. Comparison of the following parameters: color of a nucleus, integral color of a galaxy, Byurakan class, and spectral type of normal spirals gives the possibility to conclude: (1) The colors of the nuclei of the Sc galaxies have a high dispersion in its values. In all Byurakan classes the galaxies with intensely red and blue nuclei occur; (2) Some Sc galaxies exhibit a discrepancy between the spectral and morphological types. The results of colorimetry of nuclei indicate that almost all such Sc galaxies have intensely red nuclei which, naturally, provide for these late spectral types. It can be assumed that the intensely red color of the nuclei of such Sc galaxies is a result of a new type of activity of these nuclei; and (3) some Sc galaxies show the characteristics of the Markarian objects

Full Text Available Under a computerized society, technological resources become a source of identification for any community, institution or country. Globalization of information becomes a reality, all the resources having entered into a relationship of subordination with the World Wide Web, the information highways and the Internet. "Information technology - with its most important branch, data management computer science - enters a new era, in which the computer leads to the benefit of a navigable and transparent communication space, focusing on information". Therefore, in an information-based economy, information systems have been established which, based on management systems through the methods of algebra, with applications in economic engineering, have come to manage and process large volumes of data, especially in public institutions. Consequently, the Ministry of Public Affairs has implemented the “Increasing the public administration’s responsibility by modernising the information systems for generating the reports of the financial situations of public institutions” project (FOREXEBUG”, cod SMIS 34952, for which it received in 2012 non-refundable financing from the European Social Fund through the Operational Program for Developing the Administrative Capacity 2007-2013, based on which this paper will analyse the usefulness of implementing such a program in public institutions. Such a system aims to achieve a new form of reporting of budget execution and financial statements (including information related to legal commitments submitted monthly by each public institution in electronic, standardized, secure form, with increasing the reliability of data collected by cross-checking data from the treasury and providing reliable information for use by the Ministry of Finance, public institutions, other relevant institutions and the public, both at the level of detail and the consolidation possibilities at various levels, in parallel with their use for

This article presents an analysis of the health situation of a group of teenagersattending a public institution of higher education and intervention by nursing students, focused on creatingconditions for health promotion and disease prevention. This research was conducted from a quantitative,descriptive and was performed in an institution of secondary education in the period from September toNovember 2012. We worked with students and students of eighth and ninth year with a convenience sample. Themain results indicated needs in sexuality, healthy lifestyles and conflict resolution. To address these issuesevolved different strategies planned, organized, directed and controlled by the individual. We conclude that healtheducation in adolescents is a public health problem and that nurses must meet.

Framing the Problem of Radioactive Waste: Public and Institutional Perspectives

International Nuclear Information System (INIS)

Hunt, Jane

2001-01-01

Public acceptability has been the rock on which radioactive waste management plans have foundered in many countries. As a response to this, public consultation, information provision, and transparency have been recognised as necessary elements for successful development and implementation of management plans. However, the actual practice of public consultation, in many cases, fails to adequately incorporate the significance of questioning the ways in which the problem is defined, the issues that are important, and the overall 'framing' of the problem. Public framing generally differs substantially from the way in which the problem is understood by those institutions responsible for its management; further, there are differences in the ways in which different publics frame issues. These public differences may or may not be attributable to demographic factors, but are closely related to the problem context - that is, the history of relationships, structural conditions, and the cultural resources available to make sense of the issues. The author argues that it is crucial that public framing(s) are adequately taken into account in developing management initiatives, so that policies reflect these different understandings, and thus have more social purchase, in line with Grove-White and Wynne's argument that in order for radioactive waste management to become a solvable problem, it is necessary to generate social ownership of the problem. However, traditional, and even many novel, consultation processes do not comprehensively address the issue of framing, but reproduce assumptions about the nature of the problem and how it should be addressed. These assumptions are present in, for example, the institutional arrangements and scientific and technical agendas. The author reports on a project undertaken this year with Nirex entitled 'The Front of the Front End' which used repeat focus groups to directly elicit the ways in which different publics frame the issue of

Online Communication And PR in Romanian Public Administration. The Case Study of Public Institutions From Transylvania

Delia Cristina BALABAN

2016-02-01

Full Text Available New technologies such as Internet and new media introduce new challenges for public communication. Private companies from Romania use in a very creative way the new tools of Web 2.0, such as social media. In the Romanian public sector, especially in the public administration there are important steps taken towards a modern communication. Based on the example of over 40 city halls, city councils, prefectures and county councils from Transylvania, the present paper analyzes the use of new media tools in public communication by applying content analysis and in-depth interviews with the PR representatives in those institutions in two stages, 2011 and 2015. The most important advantages of online communication in public administration are high speed, cost reduction, reaching young audiences, etc. Nevertheless, there are also critical voices that express possible risks such as exclusion of audience groups that have no online media literacy.

European practices of providing of efficiency of self-organizations institutions of population in the context of public services

2017-06-01

Full Text Available The research revealed that European countries devote sufficient attention to ensuring the effectiveness of the institutions of self-organization in the context of their public services. The most common areas where they operate are a system of health, education and assistance during emergencies. The study showed that in the development of public services, there were significant transformations in terms of subject-provider. Historically it was confessional organizations working on a voluntary basis, and linked their activity with the realization of Christian mission. Subsequently, when there had been formation of a «welfare state», the state took over responsibility for the area of public services. In favor of institutions of self-organization has been a change in the system when it became clear that they are best in the provide public services, especially in the social sphere, because they are the demonstrating of social needs. The main mechanisms of cooperation between institutions of self-organization and the public sector are, first, subsidies for statutory activities of the organization. Another mechanism is delegating services or outsourcing and in this case contracts mostly are for one year with possibility of further extension. In addition there is auxiliary element of providing of effectiveness institutions of self-organization, it consists in deprivation of their donors from taxes. Although institutions of self-organization are financed mainly by public authorities, they remain independent, because they have opportunity of funding from other sources. German experience showed that the starting point in the system of public services is the understanding of the necessity of paying taxes as acknowledgment of the rights of all members of society. That is why every taxpayer expects to receive public services at the appropriate level. This unwritten rule contributes to a very high level of provision of public services through an adequate

The analytical approach takes into account a number of indicators: from the institutional identity to the scientific features, from the interactive services to the internationalisation level, in order to evaluate whether the web provides an added value in the adopted communication model and in building a relation with the users. Lights and shades emerge from this study in which good practices side examples of a much weaker science communication approach, outlining a general context where a public research institution website has been still used as a presentation tool and its interactive opportunities have not been capitalised.

Saccharomyces cerevisiae Differential Functionalization of Presumed ScALT1 and ScALT2 Alanine Transaminases Has Been Driven by Diversification of Pyridoxal Phosphate Interactions

2018-05-01

Full Text Available Saccharomyces cerevisiae arose from an interspecies hybridization (allopolyploidiza-tion, followed by Whole Genome Duplication. Diversification analysis of ScAlt1/ScAlt2 indicated that while ScAlt1 is an alanine transaminase, ScAlt2 lost this activity, constituting an example in which one of the members of the gene pair lacks the apparent ancestral physiological role. This paper analyzes structural organization and pyridoxal phosphate (PLP binding properties of ScAlt1 and ScAlt2 indicating functional diversification could have determined loss of ScAlt2 alanine transaminase activity and thus its role in alanine metabolism. It was found that ScAlt1 and ScAlt2 are dimeric enzymes harboring 67% identity and intact conservation of the catalytic residues, with very similar structures. However, tertiary structure analysis indicated that ScAlt2 has a more open conformation than that of ScAlt1 so that under physiological conditions, while PLP interaction with ScAlt1 allows the formation of two tautomeric PLP isomers (enolimine and ketoenamine ScAlt2 preferentially forms the ketoenamine PLP tautomer, indicating a modified polarity of the active sites which affect the interaction of PLP with these proteins, that could result in lack of alanine transaminase activity in ScAlt2. The fact that ScAlt2 forms a catalytically active Schiff base with PLP and its position in an independent clade in “sensu strictu” yeasts suggests this protein has a yet undiscovered physiological function.

Innovation and knowledge management are central questions of the modern world economy where the incorporation of new knowledge is determining for competition. In this context, there is a movement of pression under public research institutions for a more dynamic participation on the local innovation system. The institutions of C and T should prepare to help the companies to insert in the context of open economies and also to compete in the global market. The modernity requires flexibility and organizational changes in the research institutions. Redefinitions of their practices in relation to other aspects such as: financing sources; partnership with other organizations; definition and planning of the objectives; evaluation, diffusion and valorization of the results and the establishing of a measuring system and performance indicators. Aiming at having an effective institutional insertion on the national and regional systems of innovation, the Nuclear Technology Development Center - CDTN reformulated its strategical planning, incorporating the view of the researchers of the Center and external experts. As part of the evaluation process, CDTN organizes an annual seminar for evaluating its projects, focused on presenting the results and also on the analysis of the performance indicators. The result of this pairs review are widely informed to the Institution and is an important tool for the critical analysis of the institutional performance and for corrections to be made by the high direction. This paper presents the methodology for evaluating the results, as well as the difficulties and improvements incorporated to the process, which has been applied for three years. (author)

Theorizing the Concept of Urban Public Transportation Institutional Framework in Malaysia

Directory of Open Access Journals (Sweden)

Abd Rahman Noor Ashikin

2016-01-01

Full Text Available The trends in transportation have been changing and will continue to change over the years. Urban dwellers in developing countries require and demand for mobility and accessibility at the same growth rate of these urban areas. Often, this demand is accommodated by the increased number of private vehicles. Development of a country is closely linked with the transportation system facilities thus will have a positive impact on the economic growth and social fabric of a country. The traffic issues are always associated with private vehicles especially in any developing cities such as the Federal Territory of Kuala Lumpur. A practical, efficient and effective transport system includes traffic management, public transport, road network and infrastructure. However, sadly, at present, the traffic problems in Malaysia are resulted from ineffective public transport system which is not methodically integrated from one place to another, therefore, forcing the people to use private vehicles for daily exercise. An integrated and comprehensive approach is required as it enhances the regulatory framework, planning structure and level of services delivered. For that reason, this paper reviews the magnitude of urban public transportation institutional framework in order to improve the people’s mobility, also to respond to the major problem of urban public transportation in the major city of Malaysia. This study therefore applies a case study design and relies very much on qualitative data encompassing policies and guidelines. The findings were drawn from an early investigation of the Malaysian institutional public transport framework through literature review which looks closely into the management structure, as well as the implementation of public transportation system and its enforcement.

Ultimate internal pressure capacity assessment of SC structure

International Nuclear Information System (INIS)

Park, Hyungkui; Choi, Inkil

2013-01-01

An SC structure applied to a containment building can be quite effective. However, an SC structure cannot be applied to a containment building, because its internal pressure resistance performance has not been verified. The containment building, which undergoes ultimate internal pressure, resists the internal pressure through a pre-stress tendon. It is hard to apply a tendon to an SC structure because of its structural characteristics. Therefore, the internal pressure resistance performance of the SC structure itself should be ensured to apply it to a structure with internal pressure resistance. In this study, the suitability of an SC structure as a substitution for the tendon of a pressure resistant structure was evaluated. A containment structure model was used in this study, because it was representative structures that resistance of ultimate internal pressure be required. In this study, a nonlinear analysis was performed to evaluate and compare the behaviors of tendon model and SC structure model. By comparing the internal pressure-displacement according to the structure type, the stability of SC structure model was assessed

The Problems of Accounting in a Public Institution: The Case of Slovenia

Meta Duhovnik

2007-12-01

Full Text Available In the article the author determines that, due to changes during the privatisation process, the Slovenian framework for public institution accounting is unable to assure the relevant presentation of costs, benefits and effects. She therefore proposes certain changes based on solutions applied in the private sector accounting practices. Her conclusions and recommendations, however, are based on a need for a true and fair measurement of a public institution’s results. The recommended way to achieve this goal is the proper application of solutions included in the International Public Sector Accounting Standards issued by the International Public Sector Accounting Standards Board of the International Federation of Accountants.

Ab-initio studies of the Sc adsorption and the ScN thin film formation on the GaN(000-1)-(2 × 2) surface

International Nuclear Information System (INIS)

Guerrero-Sánchez, J.; Sánchez-Ochoa, F.; Cocoletzi, Gregorio H.; Rivas-Silva, J.F.; Takeuchi, Noboru

2013-01-01

First principles total energy calculations have been performed to investigate the initial stages of the Sc adsorption and ScN thin film formation on the GaN(000-1)-(2 × 2) surface. Studies are done within the periodic density functional theory as implemented in the PWscf code of the Quantum ESPRESSO package. The Sc adsorption at high symmetry sites results in the bridge site as the most stable structure. When a Sc monolayer is deposited above the surface the T4 site results as the most stable geometry. The Sc migration into the first Ga monolayer induces the Ga displaced ad-atom to be adsorbed at the T4-2 site. A ScN bilayer may be obtained under the Ga monolayer. Finally a ScN bilayer may be formed in the wurtzite phase above the surface. The formation energy plots show that in the moderate Ga-rich conditions we obtain the formation of a ScN bilayer under the gallium monolayer. However at N-rich conditions the formation of ScN bilayer above the surface is the most favorable structure. We report the density of states to explain the electronic structure of the most favorable geometries. - Highlights: • Studies of the initial stages in the formation of Sc and ScN structures on GaN • In the adsorption of Sc on the GaN the Br site is the most favorable geometry. • When a Sc replaces a Ga of the first monolayer the displaced Ga occupies a T4-2 site. • For Ga-rich conditions there is formation of ScN under the Ga monolayer. • In N-rich conditions there is formation of ScN in the wurtzite phase

Kramer, Beverley; Libhaber, Elena

2016-04-18

Due to the excessive service delivery loads in public hospitals supported by academic institutions in developing environments, researchers at these institutions have little time to develop scientific writing skills or to write up their research. It is imperative to expand the writing skills of researchers and train the next generation of health sciences academics in order to disseminate research findings. This study reports on the implementation of approaches for writing and publication and the extent of support to staff suffering from the overload of service delivery and of heavy teaching duties. Workshops in scientific writing and writing retreats were initiated and were offered to all staff. Feedback from participants of the writing skills workshops indicated that the workshops provided an injection of confidence and proficiency. Protected writing time resulted in 132 papers submitted to journals and 95 in preparation from 230 participants of the writing retreats over a two year period. Staff commended the off-site, collegial environment, which also supported future collaboration with new-found colleagues. This enabling environment facilitates not only the development of writing skills per se, but also the dissemination of the generated scientific knowledge. In addition, the training in writing skills of this generation will be of value in the training of future cohorts in countries with similar health care deliverables.

{sup 44} is a promising {beta}{sup +}-emitter for molecular imaging with intermediate half-life of 4 h. Due to the chemical similarity of Sc{sup 3+} to the Lu{sup 3+} and Y{sup 3+} cations, {sup 44}Sc-DOTA bioconjugates are expected to demonstrate similar properties in vivo as the {sup 177}Lu- and {sup 90}Y-bioconjugates, what is important in planning the radionuclide therapy. {sup 44}Sc can be obtained from the {sup 44}Ti/{sup 44}Sc generator. An alternative method for {sup 44}Sc production can be the irradiation of {sup 44}Ca target at small cyclotrons. The aim of our work was to optimize the parameters of {sup 44}CaCO{sub 3} irradiation and to develop a simple procedure for {sup 44}Sc separation from the calcium target. For optimization study, {sup 44}CaCO{sub 3} targets were irradiated by protons in the energy range of 5.6-17.5 MeV with 9 MeV being found to be the best energy for {sup 44}Ca irradiations. A simple and fast separation procedure of {sup 44}Sc from calcium target was developed using chelating resin Chelex 100. DOTATATE conjugate was successfully radiolabelled with high yield at elevated temperature using the produced {sup 44}Sc. While {sup 44}CaCO{sub 3} is relatively expensive, the cost of {sup 44}Sc-DOTATATE production can be reduced by target recovery. Due to low proton energy required to produce GBq activity level of {sup 44}Sc, the availability of {sup 44}Sc radioisotope could be enhanced to open new opportunities for applications in medical imaging.

Recently, significant interest in {sup 44}Sc as a tracer for positron emission tomography (PET) imaging has been observed. Unfortunately, the co-emission by {sup 44}Sc of high-energy γ rays (E{sub γ} = 1157, 1499 keV) causes a dangerous increase of the radiation dose to the patients and clinical staff. However, it is possible to produce another radionuclide of scandium—{sup 43}Sc—having properties similar to {sup 44}Sc but is characterized by much lower energy of the concurrent gamma emissions. This work presents the production route of {sup 43}Sc by α irradiation of natural calcium, its separation and purification processes, and the labeling of [DOTA,Tyr3] octreotate (DOTATATE) bioconjugate. Natural CaCO{sub 3} and enriched [{sup 40}Ca]CaCO{sub 3} were irradiated with alpha particles for 1 h in an energy range of 14.8–30 MeV at a beam current of 0.5 or 0.25 μA. In order to find the optimum method for the separation of {sup 43}Sc from irradiated calcium targets, three processes previously developed for {sup 44}Sc were tested. Radiolabeling experiments were performed with DOTATATE radiobioconjugate, and the stability of the obtained {sup 43}Sc-DOTATATE was tested in human serum. Studies of {sup nat}CaCO{sub 3} target irradiation by alpha particles show that the optimum alpha particle energies are in the range of 24–27 MeV, giving 102 MBq/μA/h of {sup 43}Sc radioactivity which creates the opportunity to produce several GBq of {sup 43}Sc. The separation experiments performed indicate that, as with {sup 44}Sc, due to the simplicity of the operations and because of the chemical purity of the {sup 43}Sc obtained, the best separation process is when UTEVA resin is used. The DOTATATE conjugate was labeled by the obtained {sup 43}Sc with a yield >98 % at elevated temperature. Tens of GBq activities of {sup 43}Sc of high radionuclidic purity can be obtainable for clinical applications by irradiation of natural calcium with an alpha beam.

Spinning cylinder experiments SC-I and SC-II: A review of results and analyses provided to the FALSIRE project

International Nuclear Information System (INIS)

Morland, E.; Sherry, A.H.

1993-01-01

A series of six large-scale experiments have been carried out at AEA Technology using the Spinning Cylinder test facility. Results from two of those experiments (SC-I and SC-II) have been provided to Project FALSIRE and are reviewed in this paper. The Spinning Cylinder tests were carried out using hollow cylinders of 1.4m outer diameter, 0.2m wall thickness and 1.3m length, containing full-length axial defects and fabricated from a modified A508 Class 3 steel. The first Spinning Cylinder test (SC-I) was an investigation of stable ductile growth induced via mechanical (primary) loading and under conditions of contained yielding. Mechanical loading was provided in the hoop direction by rotating the cylinder about its major axis within an enclosed oven. The second test (SC-II) investigated stable ductile growth under severe thermal shock (secondary) loading again under conditions of contained yielding. In this case thermal shock was produced by spraying cold water on the inside surface of the heated cylinder whilst it was rotating. For each experiment, results are presented in terms of a number of variables, eg. crack growth, temperature, stress, strain and applied K and J. In addition, an overview of the analyses of the FALSIRE Phase-1 report is also presented with respect to test SC-I and SC-II. 4 refs., 14 figs., 13 tabs

Florina Bente

2013-08-01

Full Text Available Objective - This study aims to explore the communication process within local public administration as a determinant of citizens` satisfaction. Prior work - Several authors had examined if having contact with certain service providers will affect people’s attitudes toward the service quality, but the researchers have not focused yet on the effect of citizens` contact to local authorities on satisfaction. Approach - This research seeks to address this field using an exploratory approach. Following a quantitative methodological approach, a survey was applied to a sample of 380 citizens within Western Romanian. Findings - By analyzing data it was possible to determine citizen satisfaction and to assess its relationship with costumer contact. In addition it was revealed that in Crisana Region city hall is the most frequented local public institution. Implications – The results showed a negative effect of frequency of access to local authorities on overall customer satisfaction. The effect of citizens` contact to local authorities received less attention from the academic researchers, as a need in the literature is to expand this field. Value - This research is the first to specifically examine the contact to local authorities and the effect of frequency of addressing on citizen satisfaction within Crisana Region.

INSTITUTIONAL AND CONJUNCTURAL FACTORS ACTION ON AUTONOMY IN LOCAL PUBLIC ADMINISTRATION MANAGEMENT

Directory of Open Access Journals (Sweden)

SCUTARIU PETRONELA

2016-02-01

Full Text Available Component without which the function of local public administration management would be compromised, administrative autonomy manifests under the action of various factors. From such an angle, the space of this article is dedicated to identifying the factors affecting the autonomy in management of local public administration in order to show their actions on its manifestation. By developing the present approach, beyond the incompleteness of the existing explanations relative to this sphere of interest, we have identified and highlighted the action of two sets of factors - institutional and conjunctural. Ensign turned out to be the action that institutional factors exert on autonomy, the latter being the greater, as the local administrative structure is higher, as the number of local public services is higher, when there are legal regulations that warrant it, and vice versa. Then analyzing conjunctural factors, we found that the influence of the economic crisis is, as expected, adverse to autonomy manifestation. Regarding the local development factor, we showed that a local community with a high degree of development functions without the intervention of center, a situation that favors autonomy, as opposed to a less developed community that requires the support of the center, intervention which mitigates the autonomy. By examining the action of political factor, we noticed that, although politicians define public strategies and policies that will be implemented, which gives it a positive connotation, most often autonomy suffers under the politics influence. Finally, the social organization in local collectivities provides favorable ground to the manifestation and functioning of autonomy in the management of local public administration.

Development of atomic spectroscopy methods in geological institutes of Faculty of Natural Sciences Comenius University and Slovak Academy of Science

Medved, E.

1998-01-01

Development of atomic spectrochemistry methods in Geological Institute of Faculty of Natural Sciences, Comenius University (GI FNS CU) is connected with its establishment in 1957. Its instrumental equipment and location resulted from the already existing Laboratory in the Chair for Mineralogy and Crystallography of FNS CU. In Geological Institute of Slovak Academy of Science (GI SAS) the development of atomic spectroscopy methods started later, only since 1963, when the Member of Academy, Prof. RNDr. B. Cambel, DrSc. became its director. In both institutes the methods of atomic emission spectrography were used as first. A new quality in the development started since 1969 when the Institutes moved to common buildings in Petrzalka (Bratislava), the first atomic absorption spectrometers were acquired and the Institutes were 'strengthened' by coming of Prof. Ing. E. Plsko, DrSc. In the following years the Institutes started to collaborate with some other organisations which were equipped with new facilities, e.g. in 1975 with X-ray fluorescence spectrometer, electron microprobe and in 1985 with inductively coupled plasma atomic emission spectrometer. This enabled to improve essentially the quality of research activities of both institutes in the chemical characterisation of geological materials, as well as in pedagogical work (students practice, diploma works and dissertations). In the present time characterized by new economic conditions a reduction of GI SAS laboratory activities has been realised. The laboratories of the GI FNS CU have, thanks to their director Ing. V. Stresko, PhD. shown also hence-forward a rich research, pedagogical and society activities what can be documented by numerous publications, citations, obtained awards, representations in professional societies and commissions, local and foreign advisory boards, accreditation boards etc. (author)

Limited research has examined the ways in which public health training programs equip students to address health disparities affecting the lesbian, gay, bisexual, and transgender (LGBT) community and other sexual and gender minority (SGM) populations. This study outlines the availability of public health curricula on SGM health topics, and the prevalence of LGBT and SGM-inclusive institutional support services across CEPH-accredited U.S. schools of public health. Content analysis of all course offerings related to gender and sexuality revealed a limited focus on sexual and gender minority health: just 4.7% of courses contained keywords indicating that LGBT or SGM health topics were covered. Similar analysis of institutional support services available at U.S. schools of public health found that only 25% of schools had LGBT student organizations, and just 19% had an office of diversity that specifically advertised LGBT or SGM-inclusive programming or services on the institution's Web site. Finally, only two of 52 schools offered an educational certificate centered on LGBT health. These findings illustrate a significant need for enhanced curricular content and institutional support services that equip public health students to address SGM health disparities. Improvement in this area may encourage future health care professionals to work to reduce these disparities, to improve SGM persons' experiences in health care settings, and to generate further research in this area.

The role of the State Audit Institution in prevention of white-collar crime in the public sector

Directory of Open Access Journals (Sweden)

Šuput Jelena

2014-01-01

Full Text Available In this paper, the author points out to the important role of the Serbian State Audit Institution in prevention of corruptive practices, felonies and white-collar crime in the public sector in the Republic of Serbia. Although the activity of supreme state auditors is not primarily aimed at detecting criminal offences in the public sector, their efforts and results in this area are by no means insignificant. This is due to the fact that state auditors are well-trained to interpret and apply the legal provisions from the area of public finance, public procurements and accountancy, regulating the budget system of revenues and expenditures whose violation may constitute a criminal offence within the scope of white-collar crime. Considering the fact that it is an independent and autonomous state authority, the Serbian Supreme Audit Institution should play a very important role in reducing 'the dark figures of white-collar crime'. In many cases, the fear of crime detection as well as the fear of being punished are sufficient to exert the preventive effect on the potential perpetrators of white-collar crimes. However, we have to bear in mind that the prevention of corruption and other felonies which are qualified as white-collar crime calls for a joint effort of all state institutions and citizens alike. Another fact which is very important for improving the operative quality of the Supreme Audit Institution is its membership in the International Organisation of Supreme Audit Institutions and cooperation with the Supreme Audit Institutions in other countries.

Full Text Available Obtaining single-chain variable fragments (scFv of recombinant antibodies in E. coli cells is often associated with numerous problems causing low yields or inactive conformation of the product. The aim of this work was to study the influence of staphylococcal protein A fragment fused with scFv antibodies (SpA-tag on the efficiency of expression of final product. Examination of scFv antibodies of different origin and specificity has shown that in similar expression systems fused scFv is synthesized in much higher quantities than free scFv. Furthermore, the scFv antibodies in fused form retained their antigen-binding properties and the SpA fragment the ability to bind other immunoglobulins. Thus, the proposed strategy can be considered effective in improving the efficiency of scFv-antibodies production in E. coli cells.

Real estate capitalization of Public Administration Institutions - a chance to stimulate investment and increase economic competitiveness

Directory of Open Access Journals (Sweden)

Ionut Constantin

2012-12-01

Full Text Available The divide in the development of the different European space regions, is exemplified by the different ability to attract investments between rural and urban areas. Urban areas usually assure to investors a broad availability of structures and services that rural areas cannot offer. Another limiting factor for rural areas is the difficulty the enterprises which want to localize their structures outside the urban area meet when they try to find information about the quantity and the quality of the available structures. This penalization affects also the unused real estates of the public administration institutions; these real estates could represent for the investors an important opportunity to improve area’s resources, meeting some forms of converging collaboration with the public administration institutions. POLYINVEST project aims at improving conditions for investment in the rural areas, directly tackling the development gap between the regions of the South East Europe and to develop an information system useful for those public administration institutions.

Full Text Available This paper is about the presentation of the social network of partnerships in 2010 around a Federal Institution of Higher Education – IFES, located at Minas Gerais State. The aim of this paper is to show how the practices of formal partnerships can contribute to the formation of democratic governance. The approach was quantitative, using as tool of the collecting data, a documental research. We analyzed the database of a body responsible for the management of the instruments of partnerships agreements and we classified the partner institutions in public, private, third sector, individuals and foreign institutions. The results were the construction of sociograms as a graphic representation showing the main elements of democratic governance. The survey revealed that partnerships as institutional practices can contribute for the establishment of a network of democratic governance, guided by a leading organization. Thereby, it can form partnerships of following types: public-public and public-private, permeated by the dimensions of governance (rules of governance defined, management (the practice of technology management, autonomy (respect to institutional abilities, mutuality (mutual responsibility, confidence and reciprocity (strengthening of teaching, research and extension activities. In this sense, the social network formed by partnerships can be categorized as a “network of democratic governance”.

Publication fees as a revenue source for open access publishing hold a prominent place on the agendas of researchers, policy makers, and academic publishers. This study contributes to the evolving empirical basis for funding these charges and examines how much German universities and research organisations spent on open access publication fees. Using self-reported cost data from the Open APC initiative, the analysis focused on the amount that was being spent on publication fees, and compared these expenditure with data from related Austrian (FWF) and UK (Wellcome Trust, Jisc) initiatives, in terms of both size and the proportion of articles being published in fully and hybrid open access journals. We also investigated how thoroughly self-reported articles were indexed in Crossref, a DOI minting agency for scholarly literature, and analysed how the institutional spending was distributed across publishers and journal titles. According to self-reported data from 30 German universities and research organisations between 2005 and 2015, expenditures on open access publication fees increased over the years in Germany and amounted to € 9,627,537 for 7,417 open access journal articles. The average payment was € 1,298, and the median was € 1,231. A total of 94% of the total article volume included in the study was supported in accordance with the price cap of € 2,000, a limit imposed by the Deutsche Forschungsgemeinschaft (DFG) as part of its funding activities for open access funding at German universities. Expenditures varied considerably at the institutional level. There were also differences in how much the institutions spent per journal and publisher. These differences reflect, at least in part, the varying pricing schemes in place including discounted publication fees.

Introduction: Single chain (scFv) antibodies are ideal targeting ligands due to their modular structure, high antigen specificity and affinity. These monovalent ligands display rapid tumor targeting but have limitations due to their fast urinary clearance. Methods: An anti-prostate membrane antigen (PSMA) scFv with a site-specific cysteine was expressed and evaluated in a prostate cancer xenograft model by Cu-64 PET imaging. To enhance tumor accumulation, the scFv-cys was conjugated to the co-polymer DSPE-PEG-maleimide that spontaneously assembled into a homogeneous multivalent lipid nanoparticle (LNP). Results: The targeted LNP exhibited a 2-fold increase in tumor uptake compared to the scFv alone using two different thiol ester chemistries. The anti-PSMA scFv-LNP exhibited a 1.6 fold increase in tumor targeting over the untargeted LNP. Conclusions: The targeted anti-PSMA scFv-LNP showed enhanced tumor accumulation over the scFv alone or the untargeted DOTA-micelle providing evidence for the development of this system for drug delivery. Advances in knowledge and implications for patient care: Anti-tumor scFv antibody fragments have not achieved their therapeutic potential due to their fast blood clearance. Conjugation to an LNP enables multivalency to the tumor antigen as well as increased molecular size for chemotherapy drug delivery.

The products of the reaction of Sc and dioxygen have been reinvestigated. By adding the electron-trapping molecule CC14, additional information about the IR spectra has been obtained, as well as the observation of new bands. New ab initio calculations are also performed on possible products of the Sc plus O2 reaction. The previously observed band at 722.5 per cm is assigned as the b2 mode of ScO2(-). Bands arising from ScO(+), Sc(O2)(+), and(O2)ScO are also assigned. We are still unable to assign any bands to OScO. The problems associated with the computational study of ScO2 are discussed.

The formation of endohedral metallofullerenes (EMFs) in an electric arc is reported for the mixed-metal Sc-Ti system utilizing methane as a reactive gas. Comparison of these results with those from the Sc/CH4 and Ti/CH4 systems as well as syntheses without methane revealed a strong mutual influence of all key components on the product distribution. Whereas a methane atmosphere alone suppresses the formation of empty cage fullerenes, the Ti/CH4 system forms mainly empty cage fullerenes. In contrast, the main fullerene products in the Sc/CH4 system are Sc4 C2 @C80 (the most abundant EMF from this synthesis), Sc3 C2 @C80 , isomers of Sc2 C2 @C82 , and the family Sc2 C2 n (2 n=74, 76, 82, 86, 90, etc.), as well as Sc3 CH@C80 . The Sc-Ti/CH4 system produces the mixed-metal Sc2 TiC@C2 n (2 n=68, 78, 80) and Sc2 TiC2 @C2 n (2 n=80) clusterfullerene families. The molecular structures of the new, transition-metal-containing endohedral fullerenes, Sc2 TiC@Ih -C80 , Sc2 TiC@D5h -C80 , and Sc2 TiC2 @Ih -C80 , were characterized by NMR spectroscopy. The structure of Sc2 TiC@Ih -C80 was also determined by single-crystal X-ray diffraction, which demonstrated the presence of a short Ti=C double bond. Both Sc2 TiC- and Sc2 TiC2 -containing clusterfullerenes have Ti-localized LUMOs. Encapsulation of the redox-active Ti ion inside the fullerene cage enables analysis of the cluster-cage strain in the endohedral fullerenes through electrochemical measurements. © 2016 The Authors.

Superconducting (sc) structures have to fulfill strict mechanical requirements to assure a stable operation of a cavity. Even small mechanical disturbances caused by effects like microphonic noise, pressure fluctuations of the liquid helium bath or Lorentz force detuning can change the resonance frequency of the cavity in the range of several hundred kHz. To control the slow and fast frequency variations during operation a compact frequency tuner prototype equipped with a stepper motor and a piezo actuator has been developed at the Institute for Applied Physics (IAP) of Frankfurt University. The tuner design and the results of first mechanical tests at room temperature of the first prototype are presented.

Lines of singly ionized Scandium (Sc II) along with other Iron group elements have been observed [1] in the region surrounding the massive star Eta Carinae [2,3] called the strontium filament (SrF). The last extensive analysis of Sc II was the four-decade old work of Johansson & Litzen [4], using low-resolution grating spectroscopy. To update and extend the Sc II spectra, we have made observation of Sc/Ar, Sc/Ne and Sc/Ge/Ar hollow cathode emission spectrum on the NIST high resolution FT700 UV/Vis and 2 m UV/Vis/IR Fourier transform spectrometers (FTS). More than 850 Sc II lines have been measured in the wavelength range of 187 nm to 3.2 μm. connecting a total of 152 energy levels. The present work also focuses to resolve hyperfine structure (HFS) in Sc II lines. We aim to obtain accurate transition wavelengths, improved energy levels and HFS constants of Sc II. The latest results from work in progress will be presented.Reference[1] Hartman H, Gull T, Johansson S and Smith N 2004 Astron. Astrophys. 419 215[2] Smith N, Morse J A and Gull T R 2004 Astrophys.

2016-01-01

The hydrogen storage behavior of Sc-decorated WS_2 monolayer and WS_2 nanoribbons is systematically studied by using first principles calculations based on the density functional theory. The present results indicate that an Sc-decorated WS_2 monolayer is not suitable for storing hydrogen due to the weak interaction between the monolayer WS_2 sheet and the Sc atoms. It is found that both the hybridization mechanism and the Coulomb attraction make the Sc atoms stably adsorb on the edges of WS_2 nanoribbons without clustering. The 2Sc/WS_2 NRs system can adsorb at most eight H_2 molecules with average adsorption energy of 0.20 eV/H_2. The results show that the desorption of H_2 is possible by lowering the pressure or by increasing the temperature. (paper)

Serine/arginine-rich (SR) proteins are important splicing factors which play significant roles in spliceosome assembly and splicing regulation. However, little is known regarding their biological functions in plants. Here, we analyzed the phenotypes of mutants upon depleting different subfamilies of Arabidopsis SR proteins. We found that loss of the functions of SC35 and SC35-like (SCL) proteins cause pleiotropic changes in plant morphology and development, including serrated leaves, late flowering, shorter roots and abnormal silique phyllotaxy. Using RNA-seq, we found that SC35 and SCL proteins play roles in the pre-mRNA splicing. Motif analysis revealed that SC35 and SCL proteins preferentially bind to a specific RNA sequence containing the AGAAGA motif. In addition, the transcriptions of a subset of genes are affected by the deletion of SC35 and SCL proteins which interact with NRPB4, a specific subunit of RNA polymerase II. The splicing of FLOWERING LOCUS C (FLC) intron1 and transcription of FLC were significantly regulated by SC35 and SCL proteins to control Arabidopsis flowering. Therefore, our findings provide mechanistic insight into the functions of plant SC35 and SCL proteins in the regulation of splicing and transcription in a direct or indirect manner to maintain the proper expression of genes and development.

The popularization of the nuclear sciences and its impact in the public opinion. Strategies of institutional communication

A continuous concern that is presented among those responsible for the exercise of the science and the technology in the Westerner entire world is to give to know the chore of their institutions and individuals. As in the case of several Mexican institutions, and particularly of the National Institute of Nuclear Research (ININ), one of their rector axes are to diffuse their achievements among the different social actors. A suitable vehicle to impact positively to the public opinion on the advances and tendencies of the nuclear energy it is the popularization of the science. The purpose of the popularization is to place accessible information in hands of the public and, by this, it requires of the use of talkative techniques derived of the journalism and of the public relationships, mainly, besides a basic knowledge of the scientific activity. In simple terms, it is not possible to achieve a positive image of the incomprehensible thing. By this cause, the correct understanding of the current administration of the nuclear energy represents the success or the failure of a strategy of institutional communication. Additionally, it is necessary a deep knowledge of the public opinion, in order to classify it and to have the option of to diversify the messages, of agreement with the characteristics of each segment of the public. Nevertheless their competition, the scientific popularization is centered in the construction of texts and other talkative tools, for that its acting frequently doesn't reach the effective dissemination of the messages. In this context, the use of a strategy of institutional communication represents the multi-functional option: on one hand and derived of the strategic planning, it will establish objectives, the periods of realization of the actions and the form of evaluating their efficiency; and on the other hand, it will allow the incorporation of creative solutions according with the nature of the origin institution, the space-time conditions

The thee indides were investigated via X-ray powder and single crystal diffraction: Ho{sub 6}Co{sub 2}Ga type, Immm, a = 886.7(3), b = 878.0(2), c = 932.1(3) pm, wR2 = 0.0517, 711 F{sup 2} values, 35 variables for Sc{sub 6}Co{sub 2.18}In{sub 0.82}, Ho{sub 10}Ni{sub 9}In{sub 20} type, P4/nmm, a = 1287.5(2), c = 884.7(1) pm, wR2 = 0.0642, 1221 F{sup 2} values, 63 variables for Sc{sub 10}Ni{sub 9}In{sub 19.44}, and MgCu{sub 4}Sn type, anti F 43m, a = 704.03(7) pm, wR2 = 0.0267, 101 F{sup 2} values, and 7 variables for ScCu{sub 4}In. The scandium rich indide Sc{sub 6}Co{sub 2.18}In{sub 0.82} contains two Co{sub 2} dumb-bells at Co-Co distances of 221 and 230 pm. Each cobalt atom within these dumb-bells has a tricapped trigonal prismatic coordination. The In1 site has a distorted cube-like coordination by scandium and shows a mixed occupancy (36%) with cobalt. The In2 atoms have distorted icosahedral scandium coordination. As a consequence of the small size of the scandium atoms, the In4 site in Sc{sub 10}Ni{sub 9}In{sub 19.44} shows defects and was furthermore refined with a split model leading to a new distorted variant within the family of Ho{sub 10}Ni{sub 9}In{sub 20} compounds. ScCu{sub 4}In is an ordered version of the cubic Laves phase with scandium and indium atoms in the CN16 voids of the copper substructure. The Cu-Cu distances within the three-dimensional network of corner-sharing tetrahedra are 248.6 and 249.2 pm. The crystal chemical peculiarities of these three indide structures are briefly discussed. (orig.)

Introduction Single chain (scFv) antibodies are ideal targeting ligands due to their modular structure, high antigen specificity and affinity. These monovalent ligands display rapid tumor targeting but have limitations due to their fast urinary clearance. Methods An anti-prostate membrane antigen (PSMA) scFv with a site-specific cysteine was expressed and evaluated in a prostate cancer xenograft model by Cu-64 PET imaging. To enhance tumor accumulation, the scFv-cys was conjugated to the co-polymer DSPE-PEG-maleimide that spontaneously assembled into a homogeneous multivalent lipid nanoparticle (LNP). Results The targeted LNP exhibited a 2-fold increase in tumor uptake compared to the scFv alone using two different thiol ester chemistries. The anti-PSMA scFv-LNP exhibited a 1.6 fold increase in tumor targeting over the untargeted LNP. Conclusions The targeted anti-PSMA scFv-LNP showed enhanced tumor accumulation over the scFv alone or the untargeted DOTA-micelle providing evidence for the development of this system for drug delivery. Advances in Knowledge and implications for patient care Anti-tumor scFv antibody fragments have not achieved their therapeutic potential due to their fast blood clearance. Conjugation to a LNP enables multivalency to the tumor antigen as well as increased molecular size for chemotherapy drug delivery. PMID:28126683

Full Text Available Objective. Evaluate the capacity of the federal legal framework to govern financing of health institutions in the public sector through innovative schemes –otherwise known as functional integration–, enabling them to purchase and sell health services to and from other public providers as a strategy to improve their performance. Materials and methods. Based on indicators of normative alignment with respect to functional integration across public health provider and governance institutions, content analysis was undertaken of national health programs and relevant laws and guidelines for financial coordination. Results. Significant progress was identified in the implementation of agreements for the coordination of public institutions. While the legal framework provides for a National Health System and a health sector, gaps and contradictions limit their scope. The General Register of Health is also moving forward, yet it lacks the necessary legal foundation to become a comprehensive tool for integration. The medical service exchange agreements are also moving forward based on tariffs and shared guidelines. However, there is a lack of incentives to promote the expansion of these agreements. Conclusions. It is recommended to update the legal framework for the coordination of the National Health System, ensuring a more harmonious and general focus to provide functional integration with the needed impulse.

PGRP-SC2, the member of PGRP family, plays an important role in regulation of innate immune response. In this paper, a PGRP-SC2 gene of Nile tilapia, Oreochromis niloticus (designated as On-PGRP-SC2) was cloned and its expression pattern under the infection of Streptococcus agalactiae was investigated. Sequence analysis showed main structural features required for amidase activity were detected in the deduced amino acid sequence of On-PGRP-SC2. In healthy tilapia, the On-PGRP-SC2 transcripts could be detected in all the examined tissues, with the most abundant expression in the muscle. When infected with S. agalactiae, there was a clear time-dependent expression pattern of On-PGRP-SC2 in the spleen, head kidney and brain. The assays for the amidase activity suggested that recombinant On-PGRP-SC2 protein had a Zn(2+)-dependent PGN-degrading activity. Moreover, our works showed that recombinant On-PGRP-SC2 protein could significantly reduce bacterial load in target organs attacked by S. agalactiae. These findings indicated that On-PGRP-SC2 may play important roles in the immune response to S. agalactiae in Nile tilapia. Copyright © 2016 Elsevier Ltd. All rights reserved.

The 2009 H1N1 pandemic left a legacy of mistrust in the public relative to how outbreaks of emerging infectious diseases are managed. To prepare for future outbreaks, it is crucial to explore the phenomenon of public trust in the institutions responsible for managing disease outbreaks. We investigated the evolution of public trust in institutions during and after the 2009 pandemic in Switzerland. We also explored respondents' perceptions of the prevention campaign and the roles of the government and media. A two-wave longitudinal survey was mailed to 2,400 members of the Swiss public. Wave 1 was in Spring 2009. Wave 2 was in Spring 2010. Six hundred and two participants responded in both waves. Participants indicated moderate to high levels of trust in medical organizations, the WHO, the Swiss government, the pharmaceutical industry, and the EU. On the other hand, trust in the media was low. Moreover, trust in almost all institutions decreased over time. Participants were satisfied with the amount of information received and indicated having followed official recommendations, but widespread concerns about the vaccine were evident. A large majority of participants agreed the vaccine might have unknown or undesirable side effects. Perceptions of the government's and the media's role in handling the outbreak were characterized by a substantial degree of skepticism and mistrust. Results show clear patterns of skepticism and mistrust on the part of the public relative to various institutions and their actions. Results underscore the importance of systematically investigating trust of the public relative to epidemics. Moreover, studies investigating the evolution of the public's memories of the pandemic over the coming years may be important to understand reactions to future pandemics. A systematic research program on trust can inform public health communication campaigns, enabling tailored communication initiatives.

PUBLIC ADMINISTRATION OF ECONOMIC DEVELOPMENT IN THE CONTEXT OF THE INSTITUTIONAL THEORY

Directory of Open Access Journals (Sweden)

Valentina Dudchenko

2018-01-01

Full Text Available One of the priorities of socio-economic reform in Ukraine is the modernization of the structure of the national economy and its growth. An effective structure of the economy, which will correspond to a socially oriented model of economic growth and will be based on the use of both the country’s competitive advantages in the global division of labour and the economic benefits of cooperation, will guarantee the independence of any country and will be the key to its dynamic development. The development of economic theory is due to the emergence of fundamentally new ideas, sustainable accumulation of knowledge, intellectual and meaningful updating of established concepts and theories, the formation of new scientific schools. A new paradigm of economic theory should explain the real processes in real economies, which operate on the principles of complex systems of synergistic nature and the theory of nonlinear dynamics. There is a process of theoretical polystructuredness both of mainstream and heterodoxy. An important task is to form an interdisciplinary dialogue between economists and scientists, which stipulates the relevance of the research topic.

The lifetimes of the 235 keV, 2 - state and 350 keV, 4 + state in 44 Sc have been measured via the 44 Ca(p, n) 44 Sc reaction with a pulsed proton beam. The time integral perturbed angular distribution technique with an external field was used to measure the precession angles of the 2 - and 4 + states populated by the 30 Si( 16 O, pnγ) 44 Sc reaction. The following values for the mean-lives and g-factors were obtained: π(2 - ) = 8.83(33) ns, g(2 - ) = 0.30(13) and π(4 + ) = 4.52(27)ns, g(4 + ) = 0.90(12). The results for the 2 - state support a rotational description of the negative parity states in 44 Sc. The magnetic moment of the 4 + state is compared to shell model predictions. (orig.) [de

2014-01-01

High energy resolution fluorescence-detected x-ray absorption spectroscopy and density functional theory calculations were used to investigate the local bonding and electronic structure of Sc in epitaxial wurtzite-structure Sc x Ga 1−x N films with x ≤ 0.059. Sc atoms are found to substitute for Ga atoms, accompanied by a local distortion involving an increase in the internal lattice parameter u around the Sc atoms. The local bonding and electronic structure at Sc are not affected strongly by the strain state or the defect microstructure of the films. These data are consistent with theoretical predictions regarding the electronic structure of dilute Sc x Ga 1−x N alloys. (paper)

Came, H; Doole, C; McKenna, B; McCreanor, T

Public institutions within New Zealand have long been accused of mono-culturalism and institutional racism. This study sought to identify inconsistencies and bias by comparing government funded contracting processes for Māori public health providers (n = 60) with those of generic providers (n = 90). Qualitative and quantitative data were collected (November 2014-May 2015), through a nationwide telephone survey of public health providers, achieving a 75% response rate. Descriptive statistical analyses were applied to quantitative responses and an inductive approach was taken to analyse data from open-ended responses in the survey domains of relationships with portfolio contract managers, contracting and funding. The quantitative data showed four sites of statistically significant variation: length of contracts, intensity of monitoring, compliance costs and frequency of auditing. Non-significant data involved access to discretionary funding and cost of living adjustments, the frequency of monitoring, access to Crown (government) funders and representation on advisory groups. The qualitative material showed disparate provider experiences, dependent on individual portfolio managers, with nuanced differences between generic and Māori providers' experiences. This study showed that monitoring government performance through a nationwide survey was an innovative way to identify sites of institutional racism. In a policy context where health equity is a key directive to the health sector, this study suggests there is scope for New Zealand health funders to improve their contracting practices.

2016-01-01

Twitter is a free social networking and microblogging service on the Internet. Medical professionals and patients have started to use Twitter in medicine. Twitter use by medical institutions can interactively and efficiently provide public health information and education for laypeople. This study examined Twitter usage by medical institutions. We reviewed all Japanese user accounts in which the names of medical institutions were described in the user's Twitter profile. We then classified medical institutions' tweets by content. We extracted 168 accounts for medical institutions with ≥500 followers. The medical specialties of those accounts were dentistry and oral surgery (n=73), dermatology (n=12), cosmetic surgery (n=10), internal medicine (n=10), ophthalmology (n=6), obstetrics and gynecology (n=5), plastic surgery (n=2), and others (n=50). Of these, 21 accounts tweeted medical knowledge and 45 accounts tweeted guidance about medical practice and consultation hours, including advertisements. In the dentistry and oral surgery accounts, individual behavior or thinking was the most frequent (22/71, 31%) content. On the other hand, consultation including advertisements was the most frequent (14/23, 61%) in cosmetic surgery, plastic surgery, and dermatology. Some medical specialties used Twitter for disseminating medical knowledge or guidance including advertisements. This indicates that Twitter potentially can be used for various purposes by different medical specialties.

Design of SC walls and slabs for impulsive loading

Energy Technology Data Exchange (ETDEWEB)

Varma, Amit H. [Purdue Univ., West Lafayette, IN (United States)

2015-11-11

Reinforced concrete (RC) structures have historically been the preferred choice for blast resistant structures because of their mass and the ductility provided by steel reinforcement. Steel-plate composite (SC) walls are a viable alternative to RC for protecting the infrastructure against explosive threats. SC structures consist of two steel faceplates with a plain concrete core between them. The steel faceplates are anchored to the concrete using stud anchors and connected to each other using tie bars. SC structures provide mass from the concrete infill and ductility from the continuous external steel faceplates. This dissertation presents findings and recommendations from experimental and analytical investigations of the performance of SC walls subjected to far-field blast loads.

Bangerter, Adrian; Krings, Franciska; Mouton, Audrey; Gilles, Ingrid; Green, Eva G. T.; Clémence, Alain

2012-01-01

Background The 2009 H1N1 pandemic left a legacy of mistrust in the public relative to how outbreaks of emerging infectious diseases are managed. To prepare for future outbreaks, it is crucial to explore the phenomenon of public trust in the institutions responsible for managing disease outbreaks. We investigated the evolution of public trust in institutions during and after the 2009 pandemic in Switzerland. We also explored respondents’ perceptions of the prevention campaign and the roles of the government and media. Methodology/Principal Findings A two-wave longitudinal survey was mailed to 2,400 members of the Swiss public. Wave 1 was in Spring 2009. Wave 2 was in Spring 2010. Six hundred and two participants responded in both waves. Participants indicated moderate to high levels of trust in medical organizations, the WHO, the Swiss government, the pharmaceutical industry, and the EU. On the other hand, trust in the media was low. Moreover, trust in almost all institutions decreased over time. Participants were satisfied with the amount of information received and indicated having followed official recommendations, but widespread concerns about the vaccine were evident. A large majority of participants agreed the vaccine might have unknown or undesirable side effects. Perceptions of the government’s and the media’s role in handling the outbreak were characterized by a substantial degree of skepticism and mistrust. Conclusions/Significance Results show clear patterns of skepticism and mistrust on the part of the public relative to various institutions and their actions. Results underscore the importance of systematically investigating trust of the public relative to epidemics. Moreover, studies investigating the evolution of the public’s memories of the pandemic over the coming years may be important to understand reactions to future pandemics. A systematic research program on trust can inform public health communication campaigns, enabling tailored

The role of communication in the transformation process of public institutions in Romania

2007-12-01

Full Text Available As a result of changes that take place in the Romanian economical-political-social environment before and after the integration in the European Union, the public administration must be able to rise up to the challenges that it has to confront. On the other hand, the civil society and the private sector, in order to develop, must find in the administration a partner that can facilitate communication and can offer the levers and instruments for them to express themselves and develop. A rigid administration, constrained by its own resources, norms and regulations cannot offer the most prompt answer to the needs of society, forming a barrier, often hard to surpass. That is why change should be a priority for the public administration in order to adapt to the same rhythm through a strategy that can promote communication, transparency, efficiency and effectiveness.Despite all this, it is required that the reform initiatives of the public administration to involve all factors that can contribute to the reform process: institutional, governmental factors, the European Union regulations, the requirements of the private and civil society. In order to answer to and involve all this factors, a communication strategy made and, precisely, adapted in the frame of the implementation process of the management of change is needed. In this process, the communication is answering the following wishes: the need of transparency of the decisional system; the need of communicating everything, immediately; the internal and external credibility of the institution management; the need of changing the people perception in regard to the institution, and, in this case facilitator and instrument in the change process.

Full Text Available This study evaluates the local damage of a turbine in an auxiliary building of a nuclear power plant due to an external impact by using the LS-DYNA finite element program. The wall of the auxiliary building is SC structure and the material of the SC wall plate is high manganese steel, which has superior ductility and energy absorbance compared to the ordinary steel used for other SC wall plates. The effects of the material of the wall, collision speed, and angle on the magnitude of the local damage were evaluated by local collision analysis. The analysis revealed that the SC wall made of manganese steel had significantly less damage than the SC wall made of ordinary steel. In conclusion, an SC wall made of manganese steel can have higher effective resistance than an SC wall made of ordinary steel against the local collision of an airplane engine or against a turbine impact.

高英俊; 班冬梅; 韩永剑; 钟夏平; 刘慧

2004-01-01

The valence electron structures of Al-Mg alloy with minor Sc and Zr were calculated according to the empirical electron theory(EET) in solid. The results show that because of the strong interaction of Al atom with Zr and Sc atom in melting during solidification, the Al3 Sc and Al3 (Sc1-xZrx) particles which act as heterogeneous nuclear are firstly crystallized in alloy to make grains refine. In progress of solidification, the Al-Sc, Al-Zr-Sc segregation regions are formed in solid solution matrix of Al-Mg alloy owing to the strong interaction of Al atom with Zr, Scatoms in bulk of alloy, so in the following homogenization treatment, the finer dispersed Al3 Sc and Al3 (Sc1-x Zrx) second-particles which are coherence with the matrix are precipitated in the segregation region. These finer second particles with the strong Al-Zr, Al-Sc covalent bonds can strengthen the covalent bonds in matrix of the alloy, and also enhance the hardness and strength of Al-Mg alloy. Those finer second-particles precipitated in interface of sub-grains can also strengthen the covalence bonds there, and effectively hinder the interface of sub-grains from migrating and restrain the sub-grains from growing, and cause better thermal stability of Al-Mg alloy.

In northeastern Italy, according to Italian legislation, authorized public facilities can accept the donation and preservation of cord blood stem cells (CB-SC). Attitudes and knowledge in pregnant women differs between the local and immigrant (non-European Union [EU]) population. In this study we assessed the choices that pregnant women have with respect to the public and private harvesting system and the main reasons driving their decisions. We examined the ethnic origin of the families and compared tests for syphilis screening and leukocyte (WBC) counts in the CB-SC bags that are required for validation of the collection. Out of a population of 3450 pregnant patients at the Institute for Maternal and Child Health of Trieste, northeast Italy, 772 women agreed to cord blood harvesting and the associated lab tests. Of these, 221 women (28.6%) were from immigrant families of non-EU countries. Their ethnic affiliation was recorded, and tests were performed for syphilis screening and for nucleated red blood cell (NRBC) interference with the WBC count in CB-SC bags to assess cellularity and to determine if storage was appropriate. Of the 772 pregnant women, 648 (84.0%) accessed the public collection system, which is free of charge, and 124 (15.0%) accessed the private fee-based system. One woman from the non-EU group opted for the private fee-based system. Of the 3450 pregnant women screened for syphilis at the Institute for Maternal and Child Health, the Treponema pallidum hemagglutination (TPHA) and Venereal Disease Research Laboratory (VDRL) tests were the main tests performed (66.0% of total cases) because many gynecologists in the public harvesting system apply the Italian regulations of the 1988 Decree, while the private system requires tests on syphilis and leaves the option to the lab physicians to select the best determination method. We found that the chemiluminescence method was more specific (97.0%) than the TPHA (83.0%) and nontreponemal rapid plasma reagin

Highlights: • The formation of the W phase (AlCuSc) was found in the 1469 Al-Cu–Li–Sc alloy. • The W phase formed during the homogenization process. • We model the formation process of the W phase. • The formation of the W phase consumes lots of Cu and Sc atoms. - Abstract: The present work aims to clarify the formation of the W phase (AlCuSc) and its formation time in the high Cu content alloy with Sc addition. The microstructure evolution during the two-step homogenization annealing process was investigated in the 1469 Al–Cu–Li–Sc alloy. No evidences of the Al{sub 3}Sc phase and the W phase were found in the solidification structure. The arrays of the W phases were found to form after homogenization. The AlCu phases with traces of Sc that formed during solidification suppose to be the precursor of the W phases, and then transform into the W phases by consuming the Sc atoms that fixed in the supersaturate solid solution. The formation of the W phase inhibits the precipitation of the Al{sub 3}Sc phase. A corresponding model of the W phase formation mechanism is proposed.

Full Text Available Balanced Scorecard (BSC is used to achieve an operational strategic vision at all levels of the organization regarding issues related to performance, strategy, communication, resource allocation, decision-making and competitiveness. BSC was created to restrict the limits of traditional financial and management tools and ensure unity of vision and long-term action in an organization. The main advantage of the method consists in guiding managers and departments, human resources, technological and financial resources towards the strategy of the organization. Unfortunately BSC is mainly used in private companies, because high costs and lack of specialists pose a real obstacle in implementing this instrument in public institutions. Our arguments attempts to show that the Balanced Scorecard can be the most appropriate among all the management tools for the public sector.

The Lunar and Planetary Institute's (LPI) public engagement programs target audiences of all ages and backgrounds; in 2016 LPI has expanded its programs to reach wider, more diverse audiences. The status, resources, and findings of these programs, including evaluation results, will be discussed in this poster. LPI's Cosmic Explorations Speaker Series (CESS) is an annual public speaker series to engage the public in space science and exploration. Each thematic series includes four to five presentations held between September and May. Past series' titles have included "Science" on the Silver Screen, The Universe is Out to Get Us and What We Can (or Can't) Do About It, and A User's Guide to the Universe: You Live Here. Here's What You Need to Know. While the presentations are available online after the event, they are now being livestreamed to be accessible to a broader national, and international, audience. Sky Fest events, held four to five times a year, have science content themes and include several activities for children and their parents, night sky viewing through telescopes, and scientist presentations. Themes include both planetary and astronomy topics as well as planetary exploration topics (e.g., celebrating the launch or landing of a spacecraft). Elements of the Sky Fest program are being conducted in public libraries serving audiences underrepresented in STEM near LPI. These programs take place as part of existing hour-long programs in the library. During this hour, young people, typically 6-12 years old, move through three stations where they participate in hands-on activities. Like Sky Fest, these programs are thematic, centered on one over-arching topic such as the Moon or Mars. Beginning in Fall 2016, LPI will present programs at a revitalized park in downtown Houston. Facilities at this park will enable LPI to bring both the Sky Fest and CESS programs into the heart of Houston, which is one of the most diverse cities in the US and the world.

Role of cell death in the propagation of PrP(Sc) in immune cells.

Takahashi, Kenichi; Inoshima, Yasuo; Ishiguro, Naotaka

2015-03-01

A number of studies have suggested that macrophages, dendritic cells, and follicular dendritic cells play an important role in the propagation of PrP(Sc). Both accumulation and proteolysis of PrP(Sc) have been demonstrated in peripheral macrophages. Macrophages may act as reservoirs for PrP(Sc) particles if the cells die during transient PrP(Sc) propagation. However, whether cell death plays a role in PrP(Sc) propagation in macrophages remains unclear. In this study, we investigated the possibility of propagation and transmission of PrP(Sc) between dead immune cells and living neural cells. We found that under specific conditions, transient PrP(Sc) propagation occurs in dead cells, indicating that interaction between PrP(C) and PrP(Sc) on plasma membrane lipid rafts might be important for PrP(Sc) propagation. Co-culturing of killed donor PrP(Sc)-infected macrophages with recipient N2a-3 neuroblastoma cells accelerated PrP(Sc) transmission. Our results suggest that cell death may play an important role in PrP(Sc) propagation, whereas transient PrP(Sc) propagation in macrophages has little effect on PrP(Sc) transmission.

Institutional research on public opinion and participative devices. From polls to public debate

Directory of Open Access Journals (Sweden)

Mañas, Beatriz

2012-12-01

Full Text Available Considering that the methods and techniques implemented in social research entail a certain definition of the concepts studied, it seems relevant to reflect on the possibilities of devices other than polls when studying “public opinion” as a sociological concept. Two arguments for such approach can be highlighted: the qualitative and discursive nature of public opinion, and polls’ difficulties for being collectively perceived as a reliable and interesting way to express points of view about public matters. The French CNDP (Commission Nationale du Débat Public is conceived for encouraging national, regional or local debates about political decisions which involve an important governmental investment. Taking into account that deliberative polling has probably been the most systematized among numerous research devices which have tried to implement the premises of deliberative/participative democracy, we will explore the possibilities of a different and wider representation of “public opinion” from the analysis of the dynamics generated by the institutional device of Public Debate.

Sosteniendo la hipótesis de que los métodos y técnicas utilizadas para el estudio de los conceptos de interés sociológico tienen cierta influencia en la definición de los mismos, este artículo plantea una reflexión sobre las posibilidades e implicaciones de dispositivos diferentes a las encuestas para la investigación de la opinión pública. La aproximación a este enfoque se realizará desde dos argumentaciones: por un lado, sosteniendo la naturaleza cualitativa y discursiva de la opinión pública y, por otro, mostrando la dificultad de los sondeos para ser percibidos colectivamente como un medio confiable e interesante para expresar y registrar puntos de vista sobre los asuntos públicos. La CNDP (Comisión Nacional de Debate Público es una institución pública francesa creada para animar debates nacionales, regionales o locales

The aims of this research were to: (i optimize the fermentation parameters via solid state fermentation (SSF; and (ii study the performance in hydrolysis and esterification processes of the one-step partially purified Schizophyllum commune UTARA1 lipases. Lipase was produced by cultivating S. commune UTARA1 on sugarcane bagasse (SB with used cooking oil (UCO via SSF and its production was optimized using Design-Expert® 7.0.0. Fractions 30% (ScLipA and 70% (ScLipB which contained high lipase activity were obtained by stepwise (NH42SO4 precipitation. Crude fish oil, coconut oil and butter were used to investigate the lipase hydrolysis capabilities by a free glycerol assay. Results showed that ScLipA has affinities for long, medium and short chain triglycerides, as all the oils investigated were degraded, whereas ScLipB has affinities for long chain triglycerides as it only degrades crude fish oil. During esterification, ScLipA was able to synthesize trilaurin and triacetin. Conversely, ScLipB was specific towards the formation of 2-mono-olein and triacetin. From the results obtained, it was determined that ScLipA and ScLipB are sn-2 regioselective lipases. Hence, the one-step partial purification strategy proved to be feasible for partial purification of S. commune UTARA1 lipases that has potential use in industrial applications.

Full Text Available Abstract Background Cells permissive to virus can become refractory to viral replication upon intracellular expression of single chain fragment variable (scFv antibodies directed towards viral structural or regulatory proteins, or virus-coded enzymes. For example, an intrabody derived from MH-SVM33, a monoclonal antibody against a conserved C-terminal epitope of the HIV-1 matrix protein (MAp17, was found to exert an inhibitory effect on HIV-1 replication. Results Two versions of MH-SVM33-derived scFv were constructed in recombinant baculoviruses (BVs and expressed in BV-infected Sf9 cells, N-myristoylation-competent scFvG2/p17 and N-myristoylation-incompetent scFvE2/p17 protein, both carrying a C-terminal HA tag. ScFvG2/p17 expression resulted in an insoluble, membrane-associated protein, whereas scFvE2/p17 was recovered in both soluble and membrane-incorporated forms. When coexpressed with the HIV-1 Pr55Gag precursor, scFvG2/p17 and scFvE2/p17 did not show any detectable negative effect on virus-like particle (VLP assembly and egress, and both failed to be encapsidated in VLP. However, soluble scFvE2/p17 isolated from Sf9 cell lysates was capable of binding to its specific antigen, in the form of a synthetic p17 peptide or as Gag polyprotein-embedded epitope. Significant amounts of scFvE2/p17 were released in the extracellular medium of BV-infected cells in high-molecular weight, pelletable form. This particulate form corresponded to BV particles displaying scFvE2/p17 molecules, inserted into the BV envelope via the scFv N-terminal region. The BV-displayed scFvE2/p17 molecules were found to be immunologically functional, as they reacted with the C-terminal epitope of MAp17. Fusion of the N-terminal 18 amino acid residues from the scFvE2/p17 sequence (N18E2 to another scFv recognizing CD147 (scFv-M6-1B9 conferred the property of BV-display to the resulting chimeric scFv-N18E2/M6.

Rosenthal, A. H. (Editor)

1973-01-01

Science, the overwhelming concern of our time, is no longer a matter of private research and development but one of public policy and administration, in which government, industry, foundations, and educational institutions must all work together as never before. Few other single tasks are of such decisive importance to the collective and individual welfare of American citizens as the formulation of public science policy and the administration of scientific programs. Eleven national authorities of varied background in science, education, and government administration contribute their experience and their judgment in an effort to deal with the major aspects of the subject. Their focus is on the meeting of actual problems; they consider the decision making process in both public and public-private organizations. Topics are grouped in three general categories: personnel needs and resources, organizational problems and techniques, and the administrative role in policy leadership.

The photoelectron spectra of Sc - and Y - have been obtained in a crossed ion- and laser-beam experiment. Analysis of the Sc - spectrum yields two bound terms of 3d4s 2 4p configuration ( 1 D 0 and 3 D 0 ), with EA(Sc) = 0.189 +- 0.020 eV and an excited-state binding energy of 0.042 +- 0.020 eV. Similarly, the (4d5s 2 5p) 1 D 0 ground state of Y - is bound by 0.308 +- 0.012 eV and a (4d5s 2 5p) 3 D 0 excited term is bound by 0.165 +- 0.025 eV. With the determination of the bound electronic configuration of Sc - as 3d4s 2 4p, the order of filling of electron shells of the first transition series negative ions is found to be 4s 2 ep, 3d4s 2 4p, the order of filling of electron shells of the first transition series negative ions is found to be 4s 2 4p, 3d4s 2 4p, followed by 3dsup(k) 4s 2 (k = 3, 4, ..., 10).

Although the concept that cancers originate from stem cells (SC) is becoming scientifically accepted, mechanisms by which SC contribute to tumor initiation and progression are largely unknown. For colorectal cancer (CRC), investigation of this problem has been hindered by a paucity of specific markers for identification and isolation of SC from normal and malignant colon. Accordingly, aldehyde dehydrogenase 1 (ALDH1) was investigated as a possible marker for identifying colonic SC and for tracking them during cancer progression. Immunostaining showed that ALDH1(+) cells are sparse and limited to the normal crypt bottom, where SCs reside. During progression from normal epithelium to mutant (APC) epithelium to adenoma, ALDH1(+) cells increased in number and became distributed farther up the crypt. CD133(+) and CD44(+) cells, which are more numerous and broadly distributed in normal crypts, showed similar changes during tumorigenesis. Flow cytometric isolation of cancer cells based on enzymatic activity of ALDH (Aldefluor assay) and implantation of these cells in nonobese diabetic-severe combined immunodeficient mice (a) generated xenograft tumors (Aldefluor(-) cells did not), (b) generated them after implanting as few as 25 cells, and (c) generated them dose dependently. Further isolation of cancer cells using a second marker (CD44(+) or CD133(+) serially) only modestly increased enrichment based on tumor-initiating ability. Thus, ALDH1 seems to be a specific marker for identifying, isolating, and tracking human colonic SC during CRC development. These findings also support our original hypothesis, derived previously from mathematical modeling of crypt dynamics, that progressive colonic SC overpopulation occurs during colon tumorigenesis and drives CRC development.

Full Text Available Total Quality Management (TQM is a management philosophy and approach, whose importance is growing evermore after the 90s. Kosovo's public institutions for a short time now organise activities as part of an independent state and as such they are facing ahead management challenges which are becoming more acute and in the framework of the EU integration processes. Total Quality Management in public institutions, is preceded by establishment and implementation phase ISO 9001 systems. In this paper we tried that through an empirical study in three public institutions of Kosovo, evidence the factors that facilitate or impede timely and successful implementation of quality systems and therefore of TQM. Moreover, we will concentrate on organizational culture. Analysis on the norms, beliefs, principles that characterize the organizational culture of Kosovo institutions and furthermore intertwined with the Law on Public Administration and the political context, will serve to shape the changes that need to be designed to proceed to successful implementation of TQM. In function of the analysis of impeding factors, elements of organizational culture as well as modeling the changes there will be used a number of interviews and questionnaires.

Full Text Available The aim of this paper is to analyze the par-ticularities of human resources management in the public institutions from Bihor County (Ro-mania and Hajdu-Bihar County (Hungary. The comparative dimension of our study is framed in Hofstede’s categories of cultural differences in organizational culture. The data presented is derived from a broader study conducted on the implementation of New Public Management at local public administration institutions in Ro-mania and Hungary. The project entitled ‘Es-tablishment of R&D programmes in the f eld of new public management between economic faculties of higher education in Hajdu-Bihar and Bihor Counties’ (HURO/0901/277/2.2.2 was developed in partnership between Faculties of Economics from the Universities of Oradea and Debrecen. Our results on public human resour-ces provide relevant insight in the processes re-garding personnel in the public institutions in this region and propose solutions for improvement of the observed weaknesses. The employees of the 60 public institutions included in this research consider themselves participants in the decision-al process, yet the evaluation process needs to be reshaped in order to provide a better balance between performances and the rewards system.

Polymorphous GdScO3 as high permittivity dielectric

International Nuclear Information System (INIS)

Schäfer, A.; Rahmanizadeh, K.; Bihlmayer, G.; Luysberg, M.; Wendt, F.; Besmehn, A.; Fox, A.

2015-01-01

Four different polymorphs of GdScO 3 are assessed theoretically and experimentally with respect to their suitability as a dielectric. The calculations carried out by density functional theory reveal lattice constants, band gaps and the energies of formation of three crystal phases. Experimentally all three crystal phases and the amorphous phase can be realized as thin films by pulsed laser deposition using various growth templates. Their respective crystal structures are confirmed by X-ray diffraction and transmission electron microscopy reflecting the calculated lattice constants. X-ray photoelectron spectroscopy unveils the band gaps of the different polymorphs of GdScO 3 which are above 5 eV for all films demonstrating good insulating properties. From capacitance voltage measurements, high permittivities of up to 27 for hexagonal GdScO 3 are deduced. - Highlights: • Different epitaxial polymorph phases of GdScO 3 were grown by pulsed laser deposition. • The cubic phase of GdScO 3 is reported for the first time. • All phases are proven to be useful for the use in silicon based and III–V based microelectronic devices.

We present a computational study of spontaneous polarization and piezoelectricity in Sc x Al 1−x N alloys in the compositional range from x = 0 to x = 0.5, obtained in the context of density functional theory and the Berry-phase theory of electric polarization using large periodic supercells. We report composition-dependent values of piezoelectric coefficients e ij , piezoelectric moduli d ij and elastic constants C ij . The theoretical findings are complemented with experimental measurement of e 33 for a series of sputtered ScAlN films carried out with a piezoelectric resonator. The rapid increase with Sc content of the piezoelectric response reported in previous studies is confirmed for the available data. A detailed description of the full methodology required to calculate the piezoelectric properties of ScAlN, with application to other complex alloys, is presented. In particular, we find that the large amount of internal strain present in ScAlN and its intricate relation with electric polarization make configurational sampling and the use of large supercells at different compositions necessary in order to accurately derive the piezoelectric response of the material.

Full Text Available The evaluation of texture as a function of recrystallization has been characterized for directly cold rolled Al-6Mg, Al-6Mg-0.4Sc and Al-6Mg-0.4Sc-0.2Zr alloys. Samples were annealed isothermally at 400 °C for 1 to 240 minutes to allow recrystallization. Recrystallization kinetics of the alloys is analyzed from the micro-hardness variation. Isothermally annealed samples of aluminum alloys were also studied using JMAK type analysis to see if there exists any correlation between the methods. Recrystallization fraction behavior between two methods the scandium added alloys show the higher variation due to precipitation hardening and higher recrystallization behavior. The scandium and zirconium as a combined shows the more variation due to formation of Al3(Sc, Zr precipitate. From the microstructure it is also observed that the base Al-Mg alloy attained almost fully re-crystallized state after annealing at 400 °C for 60 minutes

Jaguar Curatorship, the Poetics of the Multiple. A decolonial approach in the production of the new public institutionalism

Full Text Available The collective and the common are categories that describe and affect art practice, the new forms of creation, and the culture of curatorship. This conversation approaches them from a shared experience, the setting in motion of a Factory of Authorless Cinema in Intermediæ, a public institution of art and culture, located in Madrid's Matadero. From an auto-ethnographic and performative standpoint, we analyse the opportunities this opens up for the production of a new cultural institution. This situated understanding of curatorship and mediation allows us to discuss the role of the political epistemology of the commons in the current redefinition of the public sphere and to propose a decolonial affecting of this notion from the standpoint of multiplicity. Public, commons, rotation and temporality become the keywords that guide this text. In the construction of the problem we see how art and culture can become a space to play out new forms of governance where, on the basis of poetic models of thought, new futures for this public space we share can be created. The question is posed by a situated curatorship and mediation, in the context of the public institution, for the composition of a temporary, variable community, in constant movement and transformation, from a decolonial vantage point, which we call jaguar.

As in many other cities, urbanization coupled with population growth worsens the water supply problem of Addis Ababa, Ethiopia, with a water supply deficit of 41% in 2016. To investigate the potential contribution of rooftop rainwater harvesting (RWH) from large public institutions, 320 such institutions were selected and grouped into 11 categories, from which 25-30% representative 588 rooftops were digitalized and the potential RWH volume computed based on a ten-year rainfall dataset. When comparing the resulting RWH potential with the water consumption, up to 2.3% of the annual, potable water supply can be provided. If reused only within one's own institution, the self-sufficiency varies from 0.9 to 649%. Non-uniform rainfall patterns add uncertainty to these numbers, since the size of the storage tank becomes critical for coverage in the dry season from October to May. Despite the low replacement potential at the city level, RWH from large institutions will enable a significant volume of potable water to be transferred to localities critically suffering from water shortage. Further, large institutions may demonstrate how RWH can be practiced, thus acting as a frontrunner for the dissemination of RWH to other types of rooftops. To narrow the water supply gap, considering rooftop RWH as an alternative water supply source is recommended. However, the present study assumed that financial constraints to install large sized storage tanks are considered as a possible challenge. Thus, future research is needed to investigate the cost-benefit balance along with the invention of a cheap storage tank as they may affect the potential contribution of RWH from rooftops.

Full Text Available The professional with a bachelor in Secretarial Science is increasingly placed on the labor market, both in the private and the public sector. However, recent public service entrance examination, on several occasions, offer positions for executive secretary – in which, neither the undergraduate degree in Secretarial Science nor the professional registry is mandatory, allowing undergraduates in different areas enter the public sector as executive secretaries. On the above, this article aims at identifying and introduce the public service entrance examinations for executive secretary, specifically in the Federal Institutions of Higher Education (IFES, from 2009 to 2015. It was identified 110 public service entrance examination rules which provided 531 positions. Of these, only 308 positions (from 57 public service entrance examination rules were exclusively intended for applicants professionally qualified according to the Law No 7.377 of September 30th, 1985. It was noted that some IFES did not demand, in their public service entrance examination rules, the professional qualification required by the Circular Letter No 015/2005 from MEC, causing a loss to the professionals with the professional qualification.

Highlights: Black-Right-Pointing-Pointer We examine the creep behavior of Al-alloys with Li and rare earth element additions. Black-Right-Pointing-Pointer These alloys exhibit threshold stresses below which no measurable creep occurs. Black-Right-Pointing-Pointer Larger precipitate size and lattice parameter mismatch increase creep resistance. Black-Right-Pointing-Pointer A simple parameter describes the threshold stress behavior in ternary Al-Sc-X alloys. Black-Right-Pointing-Pointer The findings are explained by a recent model of dislocation-precipitate interactions. - Abstract: A dilute Al-Sc alloy (Al-0.12 Sc, at.%, Al-Sc), its counterpart with a Li addition (Al-2.9 Li-0.11 Sc, at.%, Al-Li-Sc), as well as a quaternary alloy (Al-5.53 Li-0.048 Sc-0.009 Yb, at.%, Al-Li-Sc-Yb) were isothermally aged at 325 Degree-Sign C, and in some cases isochronally aged to 450 Degree-Sign C. As the {alpha} Prime -Al{sub 3}(Li,Sc) and Al{sub 3}(Li,Sc,Yb) precipitates, with L1{sub 2} structure, coarsen in the two Li-containing alloys, their Li and Yb concentrations decrease and their Sc concentration increases. A significant interfacial excess of Li also segregates at the {alpha}-Al matrix/{alpha} Prime -Al{sub 3}Sc(Li,Sc,Yb) precipitate interface: 5.99 {+-} 0.05 atoms nm{sup -2} in Al-Li-Sc and 13.2 {+-} 0.4 atoms nm{sup -2} in Al-Li-Sc-Yb after aging isochronally to 450 Degree-Sign C. During compression creep at 300 Degree-Sign C, the aged alloys exhibit threshold stresses between 8 and 22 MPa. A recent threshold stress model based on elastic interactions between dislocations and precipitates predicts correctly that Li additions in the Al-Li-Sc alloy reduce the threshold stress, while Yb in the Al-Li-Sc-Yb alloy increases it. The model is also in agreement with the threshold stresses of all Al-Sc-X alloys published to date.

Local Impact Simulation of SC Wall Structures using Aircraft Engine Projectile

Chung, Chulhun; Lee, Jungwhee; Lee, Hanjoo; Jung, Raeyoung; Hyun, Changhun

2013-01-01

SC wall structure developed for nuclear power plant buildings consists of plain concrete and two steel plates on both surface of the concrete, while RC structure consists of re bar and concrete. SC structure has higher scabbing resistance than RC structure due to the action of steel plate on the rear side of impact. Therefore SC structure is known as more effective structure from the viewpoint of aircraft crash than RC structure. However, most of the recent researches and experiments about local impact damage deal with RC structures, and the effect of re bar and steel plate is not considered reasonably. Although Walter et al. and Make-work et al. suggested a formula for evaluating perforation depth of steel plate covered RC walls, most of the previous researches about SC structure are focused on perforation and scabbing due to the impact of hard projectile, rather than soft projectile such as an aircraft. In this research a soft projectile, i. e. aircraft engine, is utilized for impact simulation of RC and SC walls. To evaluate local damage of SC wall structures, parametric study with the variables of wall thickness and steel ratio of the cover plate is performed, and the results are compared with those of RC structures. Since scabbing was prevented by the steel plates, penetration mode of damage was observed in SC walls while scabbing damage was occurred in RC walls. It is confirmed that the rear steel plate not only contains concrete debris, but also reduces the internal damage of the concrete walls. Penetration depth of SC walls did not largely vary due to the increasing steel ratio, and similar results to RC walls were observed when the wall thickness is larger than a certain value since the impact resistance of SC wall is mainly governed by the thickness of concrete part. Therefore, it is expected that similar level of impact resistance to RC structure can be produced with the minimum thickness of steel plates of SC structure. According to these results, SC

Institutions and journals both have important duties relating to research and publication misconduct. Institutions are responsible for the conduct of their researchers and for encouraging a healthy research environment. Journals are responsible for the conduct of their editors, for safeguarding the research record, and for ensuring the reliability of everything they publish. It is therefore important for institutions and journals to communicate and collaborate effectively on cases relating to research integrity. To achieve this, we make the following recommendations. Institutions should: • have a research integrity officer (or office) and publish their contact details prominently; • inform journals about cases of proven misconduct that affect the reliability or attribution of work that they have published; • respond to journals if they request information about issues, such as disputed authorship, misleading reporting, competing interests, or other factors, including honest errors, that could affect the reliability of published work; • initiate inquiries into allegations of research misconduct or unacceptable publication practice raised by journals; • have policies supporting responsible research conduct and systems in place for investigating suspected research misconduct. Journals should: • publish the contact details of their editor-in-chief who should act as the point of contact for questions relating to research and publication integrity; • inform institutions if they suspect misconduct by their researchers, and provide evidence to support these concerns; • cooperate with investigations and respond to institutions' questions about misconduct allegations; • be prepared to issue retractions or corrections (according to the COPE guidelines on retractions) when provided with findings of misconduct arising from investigations; • have policies for responding to institutions and other organizations that investigate cases of research misconduct

The positron-emitting radionuclide {sup 44}Sc with a half-life of 3.97 h and a {beta}{sup +} branching of 94.3% is of potential interest for clinical PET. As so far it is available from a {sup 44}Ti/{sup 44}Sc generator in Mainz, where long-lived {sup 44}Ti decays to no-carrier-added (nca) {sup 44}Sc. The {sup 44}Sc is a trivalent metal cation and should be suitable for complexation with many well established bifunctional chelators conjugated to peptides or other molecular targeting vectors. Thus, the aim of this work was to investigate the potential of {sup 44}Sc for labeling of DOTA-conjugated peptides. DOTA-D-Phe{sup 1}-Tyr{sup 3}-octreotide (DOTATOC) was used as a model molecule to study and optimize labeling procedure. Reaction parameters such as buffer conditions, concentration of peptide, pH range, reaction temperature and time were optimized. Addition of 21 nmol of DOTATOC to {sup 44}Sc in ammonium acetate buffer pH 4.0 provided labeling yields >98% within 25 min of heating in an oil-bath at 95 Degree-Sign C. This time can be reduced to 3 min only by applying microwave supported heating. {sup 44}Sc-DOTATOC was found to be stable in 0.9% NaCl, PBS pH 7.4, fetal calf and human serums, and also in the presence of competing metal cations (Fe{sup 3+}, Ca{sup 2+}, Cu{sup 2+}, Mg{sup 2+}), as well as other ligand competitors, like EDTA and DTPA, even after almost 25 h incubation at 37 Degree-Sign C. Present study shows that nca {sup 44}Sc forms stable complexes with the macrocyclic ligand DOTA and that {sup 44}Sc-DOTATOC and analog targeting vectors may be synthesized for further preclinical and clinical investigations. - Highlights: Black-Right-Pointing-Pointer Labeling of somatostatin analouges with positron emitter {sup 44}Sc was tested. Black-Right-Pointing-Pointer DOTATOC was labeled with {sup 44}Sc isotope. Black-Right-Pointing-Pointer Optimal conditions for {sup 44}Sc-DOTATOC synthesis were found.

Institutions, public debt and growth in Europe

Directory of Open Access Journals (Sweden)

Klaus Masuch

2017-06-01

Full Text Available This paper provides empirical evidence that supports the view that the quality of institutions is an important determinant of long-term growth in European countries. It shows that an initial high government debt level coupled with institutional quality below the EU average tends to be associated with particularly poor longterm real growth performance. Interestingly, the detrimental effect of high debt levels on long-term growth seems cushioned by the presence of very sound institutions. The paper offers some evidence that sound institutions may be particularly important for long-term growth in countries in which the exchange rate tool is no longer available and less so in countries with flexible exchange rate regimes. The empirical findings on the importance of institutions are robust to various measures of output growth, different measures of institutional indicators, different sample sizes, different country groupings and to the inclusions of additional control variables.

FINANCING PUBLIC INSTITUTIONS OF ACADEMIC EDUCATION IN SPAIN

Directory of Open Access Journals (Sweden)

DRĂGUŞIN CRISTINA-PETRINA

2015-04-01

Full Text Available Currently, Spanish universities meet the educational needs of the students with a wide offer of courses and the opportunity to study at all levels. They appear as an attractive option in the context of the relatively low cost of living compared to other countries in the EU area and under conditions of a tax system controlled by the Government. Starting from the assumption that the financing model of the academic education public institutions represents the foundation of their modernization in the current society based on changes and evolution, in this paper we propose to bring into the light of the concerns of those who are interested, through a persuasive exhibit, the Spanish model and its specific features. To this end, our debate will begin with a description of the Spanish system of academic education under the decentralized model of financing imprint, continuing with the presentation of specific skills in terms of funding on the triptych template: state - autonomous communities - universities. Subsequently, our investigative approach will focus on detailing the tertiary education financing sources: public resources, private and patrimonial revenues. The end of our presentation will be intended for conclusions, through which we aim to advance our vision regarding the investigated problems. In fact, the paper is intended to be a precursor step in carrying out a comparative study between the academic education funding mechanism in Romania and the Spanish one.

2016-09-23

Publication in peer-reviewed journals is widely regarded as the preferred vehicle for research dissemination. In New Zealand, the fate and publication rates of theses produced by medical students is unknown. The aim of this study was to examine the frequency and characteristics of publications derived from research conducted by Bachelor of Medical Sciences (BMedSc(Hons)) students at the three campuses of the University of Otago Medical School, New Zealand. A total of 153 BMedSc(Hons) theses accepted at the Otago Medical School during the period of January 1995 to December 2014 were analysed. Using standardised search criteria, PubMed and Google Scholar databases were searched in October 2015 to examine the number and characteristics of publications. Overall, 50 (32.7%) out of 153 included theses resulted in 81 scientific publications. Ten (12.3%) publications featured in Australasian journals. The majority of publications were original articles (84%), with pathology and molecular biology (19%) being the most common research area. Although they did not reach statistical significance, publications in higher impact factor journals trended towards having a senior first author as opposed to a student first author (p=0.06). Although higher than reported figures from previous studies, publication rates of BMedSc(Hons) theses remain lower than expected. To improve our understanding of medical student publishing in New Zealand, formal examination of the factors hindering medical students from publishing their theses is imperative.

The gallium-containing Heusler phases ScRh{sub 2}Ga, ScPd{sub 2}Ga, TmRh{sub 2}Ga and LuRh{sub 2}Ga have been synthesized by arc-melting of the elements followed by different annealing sequences to improve phase purity. The samples have been studied by powder X-ray diffraction. The structures of Lu{sub 0.97}Rh{sub 2}Ga{sub 1.03} (Fm3m, a=632.94(5) pm, wR2=0.0590, 46 F{sup 2} values, seven variables) and Sc{sub 0.88}Rh{sub 2}Ga{sub 1.12} (a=618.91(4) pm, wR2=0.0284, 44 F{sup 2} values, six variables) have been refined from single crystal X-ray diffractometer data. Both gallides show structural disorder through Lu/Ga and Sc/Ga mixing. Temperature dependent magnetic susceptibility measurements showed Pauli paramagnetism for ScRh{sub 2}Ga, ScPd{sub 2}Ga, and LuRh{sub 2}Ga and Curie-Weiss paramagnetism for TmRh{sub 2}Ga. {sup 45}Sc and {sup 71}Ga solid state MAS NMR spectroscopic investigations of the Sc containing compounds confirmed the site mixing effects typically observed for Heusler phases. The data indicate that the effect of mixed Sc/Ga occupancy is significantly stronger in ScRh{sub 2}Ga than in ScPd{sub 2}Ga.

Ion Li+ dalam struktur Li2Sc3(PO4 dapat mengalami migrasi dari posisi terisi ke posisi kosong. Penelitian ini telah memodelkan migrasi ion Li+ dalam struktur Li2Sc3(PO4 dengan menggunakan metode bond valence sum (BVS. Metode ini dapat memprediksi bilangan oksidasi suatu atom berdasarkan jarak dengan atom-atom tetangga. Source code berbasis BVS yang digunakan adalah JUMPITER yang mensimulasi efek gaya listrik eksternal yang bertindak pada ion litium sehingga nilai BVS litium dapat dipetakan terhadap jarak. Hasil simulasi menunjukkan bahwa konduksi ion Li+ dapat terjadi pada arah [010], [101], dan [120]. Namun, lintasan konduksi ion Li+ lebih mudah terjadi pada arah [120] atau bidang ab dengan nilai maksimum BVS adalah 0,982. ABSTRACT g-phase of Li2Sc3(PO43 is a lithium super ionic conductor which can be applied as a rechargeable lithium battery. Lithium ions of g-Li2Sc3(PO43 can migrate from occupied site to vacant site. In this research, simulation of Li+ ions migration in the structure of g-Li2Sc3(PO43 carried out using bond valence sum (BVS to predict the oxidation state of Li+ion based on the distance of the ion to neighboring atoms. BVS-based code used JUMPITER to simulate the effect of external electrical force acting on the lithium ions to produce the lithium BVS value which can be mapped to the distance. The simulation results shows that Li+ ion conduction can be occurred on [010], [101], and [120] directions. However, the Li ion conduction pathway occur more easily in the direction of [120] or ab plane with the BVS maximum value is 0.982.

2016-01-01

Background Twitter is a free social networking and microblogging service on the Internet. Medical professionals and patients have started to use Twitter in medicine. Twitter use by medical institutions can interactively and efficiently provide public health information and education for laypeople. Objective This study examined Twitter usage by medical institutions. Methods We reviewed all Japanese user accounts in which the names of medical institutions were described in the user’s Twitter profile. We then classified medical institutions’ tweets by content. Results We extracted 168 accounts for medical institutions with ≥500 followers. The medical specialties of those accounts were dentistry and oral surgery (n=73), dermatology (n=12), cosmetic surgery (n=10), internal medicine (n=10), ophthalmology (n=6), obstetrics and gynecology (n=5), plastic surgery (n=2), and others (n=50). Of these, 21 accounts tweeted medical knowledge and 45 accounts tweeted guidance about medical practice and consultation hours, including advertisements. In the dentistry and oral surgery accounts, individual behavior or thinking was the most frequent (22/71, 31%) content. On the other hand, consultation including advertisements was the most frequent (14/23, 61%) in cosmetic surgery, plastic surgery, and dermatology. Conclusions Some medical specialties used Twitter for disseminating medical knowledge or guidance including advertisements. This indicates that Twitter potentially can be used for various purposes by different medical specialties. PMID:27227154

Full Text Available The effect of minor addition of Sc on microstructure, age hardening behavior, tensile properties and fracture morphology of 1460 alloy have been studied. It is found that Sc content increase from 0.11 wt% to 0.22 wt% is favorable for grain refinement in as-cast alloy but results in a coarsening of Cu-rich particles. The alloy with 0.11 wt% Sc exhibits enhanced mechanical properties and age hardening effect. Transmission electron microscopy (TEM investigations on the alloy with 0.11 wt% Sc have suggested that a large amount of Al3(Sc, Zr particles precipitated at the earlier aging may inhibit recrystallization effectively.

Sites of institutional racism in public health policy making in New Zealand.

Science.gov (United States)

Came, Heather

2014-04-01

Although New Zealanders have historically prided ourselves on being a country where everyone has a 'fair go', the systemic and longstanding existence of health inequities between Māori and non-Māori suggests something isn't working. This paper informed by critical race theory, asks the reader to consider the counter narrative viewpoints of Māori health leaders; that suggest institutional racism has permeated public health policy making in New Zealand and is a contributor to health inequities alongside colonisation and uneven access to the determinants of health. Using a mixed methods approach and critical anti-racism scholarship this paper identifies five specific sites of institutional racism. These sites are: majoritarian decision making, the misuse of evidence, deficiencies in both cultural competencies and consultation processes and the impact of Crown filters. These findings suggest the failure of quality assurance systems, existing anti-racism initiatives and health sector leadership to detect and eliminate racism. The author calls for institutional racism to be urgently addressed within New Zealand and this paper serves as a reminder to policy makers operating within other colonial contexts to be vigilant for such racism.

Public Order: Challenges of Inter-Institutional and Regional Cooperation in the Context of the Knowledge Society. A Question of Economic and Social Efficiency

Directory of Open Access Journals (Sweden)

Mariana Balan

2011-05-01

Full Text Available The context of public policies undergoes a process of rapid change due to the emergence of the dynamic knowledge-based economy and society. Public administration institutions need to adapt their material and human resources to the dynamic developments of the knowledge and information society in order to maintain efficiency and effectiveness of their scopes. One of the most fragile fields is public order and the need for improved inter-institutional cooperation at national, regional, and EU-level for achieving the objectives of ensuring citizens’ safety while safeguarding rights and liberties. The social and economic efficiency of public order policies and measures need to be reassessed and improved based on overhauled and updated inter-institutional and organisational concepts, on diversified methods of cooperation at national, regional, EU- and international level. A recent project developed in the field of public order with respect to juvenile delinquency has shown that major questions still need to be approached with respect to efficiency and effectiveness of inter-institutional cooperation with both public and private bodies, and with representatives of the non-governmental organizations. The outcomes of the project have shown that juvenile delinquency must be approached as phenomenon in the wider framework of public order, of urban and rural safety, of crime prevention and combating. One major conclusion of the project is that a new integrated model is required with respect to the intra-, and inter-institutional cooperation and dialogue, but also with respect to the skills required to work efficiently considering the challenges posed by the overall developments of a society changing towards increased knowledge and information awareness. This would allow also for improved quality assessment and effectiveness measurements based on composite process and outcome indicators for public order, and public administration, in general, as well.

2017-09-01

The synthesis of hydrogen sulfides, with the potential of high-temperature superconductivity, was recently proposed at high Tc = 203 K. It motivated us to employ an ab initio approach for the predictions of crystal structures to find the stable scandium hydrides. In addition to the earlier predicted three stoichiometries of ScH, ScH2, and ScH3, we identify three other metallic stoichiometries of ScH4, ScH6, and ScH8, which show superconductivity at significantly higher temperatures. The phases of ScH4 and ScH6, whose stability does not require extremely high pressures (ZPE), are primarily ionic compounds containing exotic quasimolecular H2 arrangements. The present electron-phonon calculations revealed the superconductive potential of ScH4 and ScH6 with estimated Tc of 98 K and 129 K at 200 GPa and 130 GPa, respectively. The superconductivity of ScHn stems from the large electron-phonon coupling associated with the wagging, bending, and intermediate-frequency modes attributed mainly to the hydrogen atoms.

1992-01-01

The hyperfine magnetic fields acting on 181 Ta nuclei at the Sc and Hf sites have been measured in Heusler alloys Co 2 Sc Sn and Co 2 Sc Ga and Co 2 Hf Sn using the Time Differential Perturbed γ-γ Angular Correlation (TDPAC) technique. The measurements were carried out using an automatic spectrometer consisting of two Ba F 2 detectors and the conventional electronics. The magnitude of hyperfine magnetic field at 181 Ta was measured for all the alloys. The signs of the were determined in the cases of Co 2 Sc Sn and Co 2 Hf Sn alloys by performing the Perturbed Angular Correlation measurements with an external polarizing magnetic field of ≅ 5 k Gauss. The hyperfine magnetic fields obtained are -187,6± 3,3 and 90,0 ± 2,1 kOe measured at 77 K for Co 2 Sc Sn and Co 2 Sc Ga alloys respectively, and -342,4 ± 10,1 kOe measured at the room temperature for Co 2 Hf Sn alloy. These results are discussed and compared with the hyperfine magnetic field systematics in Co-based Heusler alloy. (author)

A digital data acquisition system (DAS) based on a minicomputer is described which registers the failure sequences in various equipment areas of the CERN synchrocyclotron (henceforward referred to as the SC). The avalanches of failure signals which occur from time to time are tapped from the alarm/security systems, time-resolved to 10 msec and recorded on a printer in order to aid SC failure diagnosis. The mechanisms of the DAS and its relation to the SC equipment are explained in some detail. All programs were constructed at assembler language level for speed and for ease of on-line program maintenance. The alarm sequences recorded have been of considerable help during the running in of the new radiofrequency system. Now that the new SC is operational, the DAS furnishes useful data from several equipment areas to the operators and engineers.

Full Text Available The article is aimed at researching the world experience of efficient interaction between the public and private sectors, defining the main advantages of the implementation of public-private partnership (PPP relations, identifying problems in the legislative base on regulation of the PPP process in Ukraine. Introduction and formation of public-private partnership as an instrument of attraction of investment resources and interaction of public and private sectors are considered. It has been found that lack of financing and negative experience of privatization of the State property caused the introduction of the PPP institute in the world practice. However, there is no single unified approach to the regulation of relations in the sphere of PPP presently, which would meet the needs of all countries. In Ukraine, this mechanism is being implemented, but it is not a widespread practice because of terminological discrepancies and lack of a uniform procedure for providing the State support to the implementation of PPP. The advantages of the PPP implementation for the public and private sectors have been determined.

Li and Sc metals functionalized on the delocalized π -electrons of benzene rings in [2,2]paracyclophane structure are studied for hydrogen storage efficiency by using the M06 DFT functional with 6-311G(d,p) basis set. It is found that Sc and Li functionalized [2,2]paracyclophane complexes can hold up to 10 H2 molecules and 8 H2 molecules by Kubas-Niu-Jena interaction and charge polarization mechanism with hydrogen weight percentage of 11.4 and 13.5, respectively. Molecular dynamics simulation at various temperatures showed appreciable thermal stability while the chemical potential calculation at room temperature reveals that Sc functionalized [2,2]paracyclophane system will be a promising hydrogen storage material.

Toward low-cost affinity reagents: lyophilized yeast-scFv probes specific for pathogen antigens.

Directory of Open Access Journals (Sweden)

Sean A Gray

Full Text Available The generation of affinity reagents, usually monoclonal antibodies, remains a critical bottleneck in biomedical research and diagnostic test development. Recombinant antibody-like proteins such as scFv have yet to replace traditional monoclonal antibodies in antigen detection applications, in large part because of poor performance of scFv in solution. To address this limitation, we have developed assays that use whole yeast cells expressing scFv on their surfaces (yeast-scFv in place of soluble purified scFv or traditional monoclonal antibodies. In this study, a nonimmune library of human scFv displayed on the surfaces of yeast cells was screened for clones that bind to recombinant cyst proteins of Entamoeba histolytica, an enteric pathogen of humans. Selected yeast-scFv clones were stabilized by lyophilization and used in detection assay formats in which the yeast-scFv served as solid support-bound monoclonal antibodies. Specific binding of antigen to the yeast-scFv was detected by staining with rabbit polyclonal antibodies. In flow cytometry-based assays, lyophilized yeast-scFv reagents retained full binding activity and specificity for their cognate antigens after 4 weeks of storage at room temperature in the absence of desiccants or stabilizers. Because flow cytometry is not available to all potential assay users, an immunofluorescence assay was also developed that detects antigen with similar sensitivity and specificity. Antigen-specific whole-cell yeast-scFv reagents can be selected from nonimmune libraries in 2-3 weeks, produced in vast quantities, and packaged in lyophilized form for extended shelf life. Lyophilized yeast-scFv show promise as low cost, renewable alternatives to monoclonal antibodies for diagnosis and research.

Primary particles with faceted cubic morphology were produced in as-cast Al-Mg alloy due to the addition of Sc. The cross-section of the particles revealed some eutectic structure composed of multilayer of 'Al{sub 3}Sc + α-Al + Al{sub 3}Sc..'. At the cooling rate of 200 - 300 K/s, Al{sub 3}Sc primary phase nucleated initially on oxides within the melt and developed to a cubic structure with a 'cellular-dendritic' mode of growth. The formation of α-Al structural shells was attributed as a reason for the segregation of Mg-rich lamellar dendrites at later stages. A growth mechanism for multilayer structure was proposed using the results presented.

This paper presents a novel narrowband interference (NBI) mitigation scheme for SC-FDMA systems. The proposed scheme exploits the frequency domain sparsity of the unknown NBI signal and adopts a low complexity Bayesian sparse recovery procedure. In practice, however, the sparsity of the NBI is destroyed by a grid mismatch between NBI sources and SC-FDMA system. Towards this end, an accurate grid mismatch model is presented and a sparsifying transform is utilized to restore the sparsity of the unknown signal. Numerical results are presented that depict the suitability of the proposed scheme for NBI mitigation.

They crystallize with a new cubic structure type, space group F m anti 3, a = 1772.5(6) pm, wR2 = 0.032, 1111 F{sup 2} values, 34 variables for Sc{sub 50}Rh{sub 13.3}In{sub 2.7}, a = 1766.5(6) pm, wR2 = 0.041, 745 F{sup 2} values, 34 variables for Sc{sub 50}Ir{sub 13.6}In{sub 2.4}, a = 1764.4(2) pm, wR2 = 0.044, 640 F{sup 2} values, 41 variables for Sc{sub 49.2}Rh{sub 13}In{sub 3.8}O{sub 8.8}, and a = 1761.5(6) pm, wR2 = 0.054, 740 F{sup 2} values, 42 variables for Sc{sub 49.2}Rh{sub 13.7}In{sub 2.8}O{sub 8.0}. The main structural motifs are rhodium-centered indium cubes in an fcc like arrangement in which the octahedral and tetrahedral voids are filled by In2Sc{sub 12} and In1Sc{sub 12} icosahedra, respectively, resembling a Li{sub 3}Bi-like structure. The Rh1 (Ir1) and Sc4 atoms lie between these polyhedral units. The oxygen atoms partially fill Sc{sub 6} octahedra in Sc{sub 49.2}Rh{sub 13}In{sub 3.8}O{sub 8.8} and Sc{sub 49.2}Rh{sub 13.7}In{sub 2.8}O{sub 8.0} with Sc-O distances of 214 - 230 pm. These octahedra are condensed via common edges and faces, encapsulating the In2Sc{sub 12} icosahedra. Due to the high scandium content one observes strong Sc-Sc bonding with Sc-Sc distances ranging from 303 to 362 pm in Sc{sub 49.2}Rh{sub 13}In{sub 3.8}O{sub 8.8}. The shortest distances occur for Sc-Rh (267 - 295 pm). The crystal chemical relationship with the Li{sub 3}Bi-related suboxide Ti{sub 12}Sn{sub 3}O{sub 10} is discussed. (orig.)

Highlights: • An idealized static resistance function for SC walls is proposed. • The influence of design parameters on static resistance is explained. • SDOF models can accurately estimate global response of SC walls to missile impact. - Abstract: Steel-plate composite (SC) walls consist of a plain concrete core reinforced with two steel faceplates on the surfaces. Modules (consisting of steel faceplates, shear connectors and tie-bars) can be shop-fabricated and shipped to the site for erection and concrete casting, which expedites construction schedule and thus economy. SC structures have recently been used in nuclear power plant designs and are being considered for the next generation of small modular reactors. Design for impactive and impulsive loading is an important consideration for SC walls in safety-related nuclear facilities. The authors have previously developed design methods to prevent local failure (perforation) of SC walls due to missile impact. This paper presents the development of static resistance functions for use in single-degree-of-freedom (SDOF) analyses to predict the maximum displacement response of SC walls subjected to missile impact and designed to resist local failure (perforation). The static resistance function for SC walls is developed using results of numerical analyses and parametric studies conducted using benchmarked 3D finite element (FE) models. The influence of various design parameters are discussed and used to develop idealized bilinear resistance functions for SC walls with fixed edges and simply supported edges. Results from dynamic non-linear FE analysis of SC panels subjected to rigid missile impact are compared with the maximum displacements predicted by SDOF analyses using the bilinear resistance function.

2017-08-02

The generalized gradient approximation (GGA) function based on density functional theory is adopted to investigate the optimized geometrical structure, electron structure and hydrogen storage performance of Sc modified porous graphene (PG). It is found that the carbon ring center is the most stable adsorbed position for a single Sc atom on PG, and the maximum number of adsorbed H₂ molecules is four with the average adsorption energy of -0.429 eV/H₂. By adding a second Sc atom on the other side of the system, the hydrogen storage capacity of the system can be improved effectively. Two Sc atoms located on opposite sides of the PG carbon ring center hole is the most suitable hydrogen storage structure, and the hydrogen storage capacity reach a maximum 9.09 wt % at the average adsorption energy of -0.296 eV/H₂. The adsorption of H₂ molecules in the PG system is mainly attributed to orbital hybridization among H, Sc, and C atoms, and Coulomb attraction between negatively charged H₂ molecules and positively charged Sc atoms.

Roberts syndrome and SC phocomelia (RBS/SC) are genetic autosomal recessive syndromes caused by establishment of cohesion 1 homolog 2 ( ESCO 2) mutation. RBS/SC appear to have a variety of clinical features, even with the same mutation of the ESCO2 gene. Here, we established and genetically characterized a medaka model of RBS/SC by reverse genetics. The RBS/SC model was screened from a mutant medaka library produced by the Targeting Induced Local Lesions in Genomes method. The medaka mutant carrying the homozygous mutation at R80S in the conserved region of ESCO2 exhibited clinical variety (i.e. developmental arrest with craniofacial and chromosomal abnormalities and embryonic lethality) as characterized in RBS/SC. Moreover, widespread apoptosis and downregulation of some gene expression, including notch1a, were detected in the R80S mutant. The R80S mutant is the animal model for RBS/SC and a valuable resource that provides the opportunity to extend knowledge of ESCO2. Downregulation of some gene expression in the R80S mutant is an important clue explaining non-correlation between genotype and phenotype in RBS/SC. © 2012 The Authors Development, Growth & Differentiation © 2012 Japanese Society of Developmental Biologists.

Regulation of axonal fasciculation plays an important role in the precise patterning of neural circuits. Selective fasciculation contributes to the sorting of different types of axons and prevents the misrouting of axons. However, axons must defasciculate once they reach the target area. To study the regulation of fasciculation, we focused on the primary vestibulo-cerebellar afferents (PVAs), which show a dramatic change from fasciculated axon bundles to defasciculated individual axons at their target region, the cerebellar primordium. To understand how fasciculation and defasciculation are regulated in this system, we investigated the roles of murine SC1-related protein (MuSC), a molecule belonging to the immunoglobulin superfamily. We show: (i) by comparing 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (Dil) labelling and anti-MuSC immunohistochemistry, that downregulation of MuSC in PVAs during development is concomitant with the defasciculation of PVA axons; (ii) in a binding assay with cells expressing MuSC, that MuSC has cell-adhesive activity via a homophilic binding mechanism, and this activity is increased by multimerization; and (iii) that MuSC also displays neurite outgrowth-promoting activity in vestibular ganglion cultures. These findings suggest that MuSC is involved in axonal fasciculation and its downregulation may help to initiate the defasciculation of PVAs.

Improved Soluble ScFv ELISA Screening Approach for Antibody Discovery Using Phage Display Technology.

Phage display technology (PDT) is a powerful tool for the isolation of recombinant antibody (Ab) fragments. Using PDT, target molecule-specific phage-Ab clones are enriched through the "biopanning" process. The individual specific binders are screened by the monoclonal scFv enzyme-linked immunosorbent assay (ELISA) that may associate with inevitable false-negative results. Thus, in this study, three strategies were investigated for optimization of the scFvs screening using Tomlinson I and J libraries, including (1) optimizing the expression of functional scFvs, (2) improving the sensitivity of ELISA, and (3) preparing different samples containing scFvs. The expression of all scFv Abs was significantly enhanced when scFv clones were cultivated in the terrific broth (TB) medium at the optimum temperature of 30 °C. The protein A-conjugated with horseradish peroxidase (HRP) was found to be a well-suited reagent for the detection of Ag-bound scFvs in comparison with either anti-c-myc Ab or the mixing procedure. Based on our findings, it seems there is no universal media supplement for an improved expression of all scFvs derived from both Tomlinson I and J libraries. We thus propose that expression of scFv fragments in a microplate scale is largely dependent on a variety of parameters, in particular the scFv clones and relevant sequences.

They have shown promise in preclinical/clinical development but feature stoichiometrically undefined chemical linkages, and those based on full-size antibodies achieve only limited tumor penetration. SNAP-tag technology can overcome these challenges by conjugating benzylguanine-modified toxins to single-chain fragment variables (scFvs with 1:1 stoichio­metry while preserving antigen binding. Two (human and mouse scFv-SNAP fusion proteins recognizing the epidermal growth factor receptor (EGFR were expressed in HEK 293T cells. The purified fusion proteins were conjugated to auristatin F (AURIF. Binding activity was confirmed by flow cytometry/immunohistochemistry, and cytotoxic activity was confirmed by cell viability/apoptosis and cell cycle arrest assays, and a novel microtubule dynamics disassembly assay was performed. Both ADCs bound specifically to their target cells in vitro and ex vivo, indicating that the binding activity of the scFv-SNAP fusions was unaffected by conjugation to AURIF. Cytotoxic assays confirmed that the ADCs induced apoptosis and cell cycle arrest at nanomolar concentrations and microtubule disassembly. The SNAP-tag technology provides a platform for the development of novel ADCs with defined conjugation sites and stoichiometry. We achieved the stable and efficient linkage of AURIF to human or murine scFvs using the SNAP-tag technology, offering a strategy to

To evaluate the quality assurance of mammography results at a reference institution for the diagnosis and treatment of breast cancer in southern Brazil, based on the BIRADS (Breast Imaging Reporting and Data System) 5th edition recommendations for auditing purposes. Retrospective cohort and cross-sectional study with 4502 patients (9668 mammographies)) who underwent at least one or both breast mammographies throughout 2013 at a regional public hospital, linked to a federal public university. The results were followed until 31 December 2014, including true positives (TPs), true negatives (TNs), false positives (FPs), false negatives (FNs), positive predictive values (PPVs), negative predictive value (NPV), sensitivity and specificity, with a confidence interval of 95%. The study showed high quality assurance, particularly regarding sensitivity (90.22%) and specificity (92.31%). The overall positive predictive value (PPV) was 65.35%, and the negative predictive value (NPV) was 98.32%. The abnormal interpretation rate (recall rate) was 12.26%. The results are appropriate when compared to the values proposed by the BIRADS 5th edition. Additionally, the study provided self-reflection considering our radiological practice, which is essential for improvements and collaboration regarding breast cancer detection. It may stimulate better radiological practice performance and continuing education, despite possible infrastructure and facility limitations. • Accurate quality performance rates are possible despite financial and governmental limitations. • Low-income institutions should develop standardised teamwork to improve radiological practice. • Regular mammography audits may help to increase the quality of public health systems.

Essays on the Impacts of Geography and Institutions on Access to Energy and Public Infrastructure Services

Science.gov (United States)

Archibong, Belinda

While previous literature has emphasized the importance of energy and public infrastructure services for economic development, questions surrounding the implications of unequal spatial distribution in access to these resources remain, particularly in the developing country context. This dissertation provides evidence on the nature, origins and implications of this distribution uniting three strands of research from the development and political economy, regional science and energy economics fields. The dissertation unites three papers on the nature of spatial inequality of access to energy and infrastructure with further implications for conflict risk , the historical institutional and biogeographical determinants of current distribution of access to energy and public infrastructure services and the response of households to fuel price changes over time. Chapter 2 uses a novel survey dataset to provide evidence for spatial clustering of public infrastructure non-functionality at schools by geopolitical zone in Nigeria with further implications for armed conflict risk in the region. Chapter 3 investigates the drivers of the results in chapter 2, exploiting variation in the spatial distribution of precolonial institutions and geography in the region, to provide evidence for the long-term impacts of these factors on current heterogeneity of access to public services. Chapter 4 addresses the policy implications of energy access, providing the first multi-year evidence on firewood demand elasticities in India, using the spatial variation in prices for estimation.

However, the empirical evidence concerning Frey's proposition is limited, and our article aims to fill part of this gap....... We investigate how the introduction of financial incentives to publish affects the number of publications at 162 Danish research institutions (17 government research institutions and subunits of 10 universities) when the perception of the incentives is taken into account. The results show...

Valentin Ioan UŞURELU

2010-12-01

Full Text Available The studied field has suffered continuous transformation, both in interaction with other scientific fields and in constituent sub-classes, for discovering and understanding more deeply the contemporary economic realities under the impact of major trends of world development. This paper aims to analyze the location and the effects of information and communication technologies within the public accounting in order to evaluate the effects of this element on accounting research, teaching and professional practice. In a comprehensive approach of public institutions accounting, new information and communication technologies represent a tool that facilitates the accounting function and realizes the connection between the transmitter and the receiver, both within and outside the organization, not just at the micro and macro economic level but also at the micro and macro social one. The advantages of recent progress of information and communication technologies are obvious for the organizations management. It highlights the developments and challenges represented by these new technologies for researchers and professionals in the idea of performing a broad and flexible view of public accounting enabling them to provide useful services for all categories of users of accounting information.

SC-HTGR Performance Impact for Arid Sites

International Nuclear Information System (INIS)

Lommers, L.; Geschwindt, J.; Southworth, F.; Shahrokhi, F.

2014-01-01

The SC-HTGR provides high temperature steam which can support industrial process heat applications as well as high efficiency electricity generation. The increased generating efficiency resulting from using high steam temperature provides greater plant output than lower temperature concepts, and it also reduces the fraction of waste heat which must be rejected. This capability is particularly attractive for sites with little or no water for heat rejection. This high temperature capability provides greater flexibility for these sites, and it results in a smaller performance penalty than for lower temperature systems when dry cooling must be used. The performance of the SC-HTGR for a conventional site with wet cooling is discussed first. Then the performance for arid sites is evaluated. Dry cooling performance is evaluated for both moderately arid sites and very hot sites. Offdesign performance of the dry cooling system under extreme conditions is also considered. Finally, operating strategies are explored for sites where some cooling water may be available but only in very limited quantities. Results of these assessments confirm that the higher operating temperatures of the SC-HTGR are very beneficial for arid sites, providing significant advantages for both gross and net power generation.

Sc-Decorated Porous Graphene for High-Capacity Hydrogen Storage: First-Principles Calculations

Directory of Open Access Journals (Sweden)

Yuhong Chen

2017-08-01

Full Text Available The generalized gradient approximation (GGA function based on density functional theory is adopted to investigate the optimized geometrical structure, electron structure and hydrogen storage performance of Sc modified porous graphene (PG. It is found that the carbon ring center is the most stable adsorbed position for a single Sc atom on PG, and the maximum number of adsorbed H2 molecules is four with the average adsorption energy of −0.429 eV/H2. By adding a second Sc atom on the other side of the system, the hydrogen storage capacity of the system can be improved effectively. Two Sc atoms located on opposite sides of the PG carbon ring center hole is the most suitable hydrogen storage structure, and the hydrogen storage capacity reach a maximum 9.09 wt % at the average adsorption energy of −0.296 eV/H2. The adsorption of H2 molecules in the PG system is mainly attributed to orbital hybridization among H, Sc, and C atoms, and Coulomb attraction between negatively charged H2 molecules and positively charged Sc atoms.

2004-01-01

In this paper La-Sc-Mo cathode has been prepared and its electron emission ability was measured. This type of cathode shows good electron emission performance that the saturated current density is 6.74 A cm -1 and the work function is about 2.59 eV at 1300 deg. C, which is much lower than thoriated tungsten cathode (Th-W). So it is a potential cathode to replace the Th-W cathode with radioactive pollution. Surface analysis shows that good emission ability due to the 20 nm surplus La layer and the element Sc may do good to the La diffusion to the surface

4SC-202 activates ASK1-dependent mitochondrial apoptosis pathway to inhibit hepatocellular carcinoma cells

International Nuclear Information System (INIS)

Fu, Meili; Wan, Fuqiang; Li, Zhengling; Zhang, Fenghua

2016-01-01

The aim of the present study is to investigate the potential anti-hepatocellular carcinoma (HCC) cell activity by 4SC-202, a novel class I HDAC inhibitor (HDACi). The associated signaling mechanisms were also analyzed. We showed that 4SC-202 treatment induced potent cytotoxic and proliferation–inhibitory activities against established HCC cell lines (HepG2, HepB3, SMMC-7721) and patient-derived primary HCC cells. Further, adding 4SC-202 in HCC cells activated mitochondrial apoptosis pathway, which was evidenced by mitochondrial permeability transition pore (mPTP) opening, cytochrome C cytosol release and caspase-3/-9 activation. Inhibition of this apoptosis pathway, by caspase-3/-9 inhibitors, mPTP blockers, or by shRNA-mediated knockdown of cyclophilin-D (Cyp-D, a key component of mPTP), significantly attenuated 4SC-202-induced HCC cell death and apoptosis. Reversely, over-expression of Cyp-D enhanced 4SC-202's sensitivity in HCC cells. Further studies showed that 4SC-202 induced apoptosis signal-regulating kinase 1 (ASK1) activation, causing it translocation to mitochondria and physical association with Cyp-D. This mitochondrial ASK1-Cyp-D complexation appeared required for mediating 4SC-202-induced apoptosis activation. ASK1 stable knockdown by targeted-shRNAs largely inhibited 4SC-202-induced mPTP opening, cytochrome C release, and following HCC cell apoptotic death. Together, we suggest that 4SC-202 activates ASK1-dependent mitochondrial apoptosis pathway to potently inhibit human HCC cells. - Highlights: • 4SC-202 exerts potent anti-proliferative and cytotoxic activity against established/primary HCC cells. • SC-202-induced anti-HCC cell activity relies on caspase-dependent apoptosis activation. • 4SC-202 activates Cyp-D-dependent mitochondrial apoptosis pathway in HCC cells. • 4SC-202 activates ASK1 in HCC cells, causing it translocation to mitochondria. • Mitochondrial ASK1-Cyp-D complexation mediates 4SC-202's activity in HCC cells.

Thermoelectric performance of functionalized Sc2C MXenes

KAUST Repository

Kumar, S.; Schwingenschlö gl, Udo

2016-01-01

Functionalization of the MXene Sc2C, which has the rare property to realize semiconducting states for various functionalizations including O, F, and OH, is studied with respect to the electronic and thermal behavior. The lowest lattice thermal conductivity is obtained for OH functionalization and an additional 30% decrease can be achieved by confining the phonon mean free path to 100 nm. Despite a relatively low Seebeck coefficient, Sc2C(OH)2 is a candidate for intermediate-temperature thermoelectric applications due to compensation by a high electrical conductivity and very low lattice thermal conductivity.

ZnO-based scintillators are particularly well suited for use as ultrafast pulsed radiation detectors which have shown broad application prospects in various fields such as the inertial confinement fusion (ICF) diagnosis, the nuclear reaction mechanism, etc. Using the hydro-thermal method, a ZnO single-crystal doped with Scandium (ZnO:Sc) sample was prepared. As a new ZnO-based scintillator, the scintillation characteristics of ZnO:Sc have not been reported previously. In this paper, optical and scintillation characteristics of ZnO:Sc single-crystal were studied. Also a scintillation detector based on ZnO:Sc was designed. Excited by the alpha-particle, the rise time of ZnO:Sc detectors was from 162.5 to 170.7 ps, and the fall time was from 300.4 to 328.8 ps.

Nichols, Nicole L; Wilkinson, Katherine A; Powell, Frank L; Dean, Jay B; Putnam, Robert W

2009-09-30

We studied the effect of chronic hypobaric hypoxia (CHx; 10-11% O(2)) on the response to hypercapnia (15% CO(2)) of individual solitary complex (SC) neurons from adult rats. We simultaneously measured the intracellular pH and firing rate responses to hypercapnia of SC neurons in superfused medullary slices from control and CHx-adapted adult rats using the blind whole cell patch clamp technique and fluorescence imaging microscopy. We found that CHx caused the percentage of SC neurons inhibited by hypercapnia to significantly increase from about 10% up to about 30%, but did not significantly alter the percentage of SC neurons activated by hypercapnia (50% in control vs. 35% in CHx). Further, the magnitudes of the responses of SC neurons from control rats (chemosensitivity index for activated neurons of 166+/-11% and for inhibited neurons of 45+/-15%) were the same in SC neurons from CHx-adapted rats. This plasticity induced in chemosensitive SC neurons by CHx appears to involve intrinsic changes in neuronal properties since they were the same in synaptic blockade medium.

DEVELOPMENT OF A REFERENCE MODEL TO INTEGRATED DESIGN MANAGEMENT ON PUBLIC INSTITUTIONS

Directory of Open Access Journals (Sweden)

Paulo Roberto Andery

2012-06-01

Full Text Available The present paper aims discussing the design process carried out in public institutions. Since there are different players in the design process, including designers, coordinators, bureaucratic managers, the design development brings some problems that come from the lack of a contracting and design development model, as well as in the information flow between its stakeholders. Rework, delays in contracts deadlines and low quality of the final product are not unusual. Due to the complexity of the design process, it has been searched in the process modeling a valid option to fulfill that blank. A Referential Term was developed by creating a work flow to the institution’s design process through the systematization of solutions developed by other researchers. The mentioned Term makes possible a clear understanding of the design process, leads to the definition of each player responsibilities, defines design phases, providing a general plan and establishing a detailed and integrated vision of the job made by every agent involved. The research was conducted by the implementation of this Term of reference in two Projects of the institution. It is briefly presented an analysis of main aspects of the implementation, highlighting the improvement of contractual relations between designers and the institution, reduction of design duration, improvement in the information flow, as well as a better collaborative environment.

Full Text Available The problem of dishonesty and distrust is often unclear phenomena in Eastern Europe. These are common issues discussed not only in print media and television, but also social environments as well. Corruption, so unfair advantage, lies, deceit and abuse of trust are mentioned frequently during the last decades a" er the change of system in the region, especially in Balkan Peninsula. Although dishonesty and distrust (+ corruption have existed in the previous system, however, they have been hidden phenomena or issues for which there is talk in this system. Research in terms of honesty and trust include a more areas in different sectors. International literature on the subject focuses on two fundamental topics. One of which is his faith and relationship with social capital. What do some of these concepts mean in our perception? What are the benefits and harmful effects of faith and are those connected with social equity and democratic consolidation? The search for this topic is interdisciplinary because it includes political sciences, social sciences, political, legal or sociologic-and those of anthropology. As a result this thesis will provide comparative scale impasse that creates two realities of different social complexity, from the countries that have experienced the post-socialist transition, belief in family and society that retains a holding in the operations of public institutions and may create difficulties to succeed the efforts to implement the law impartially. In conclusion: Corruption is an unreliable source, which comprises behavior and violates the trust placed on official- and public officials. It includes the use of public positions for personal benefit and it creates an ill infrastructure for fragile democracies.

Full Text Available In this bibliometric study we discuss the institutional complexity in eleven journals in business administration and organization studies. We try to identify the main features of the present Institutional Theory discussion in organization theory. The main research techniques we used were citation, co-citation, factorial bibliometric analysis and multidimensional scaling to identify the most influential studies and the main themes that are interwoven in institutional complexity (institutional logics, conflicts, changes and identity. The sample consisted of 43 articles and more than 3000 references cited. The most cited works were grouped into three factors that represent the emergent topics in institutional complexity. The results show the emergence of a new set of important concepts in the context of the institutional theory, such as institutional logics, conflict, change, identity, strategy. That set of concepts is diverse from that one typical of the institutionalism in organizations, in the 90´s. Complementarily, we identify authors and papers that can be considered central in organizational institutionalism, according to the journals that we take as part of our sample.

Shortell, Stephen M.; Weist, Elizabeth M.; Sow, Mah-Sere Keita; Foster, Allison; Tahir, Ramika

2004-01-01

In September 2003, the Association of Schools of Public Health administered an online survey to representatives of all 33 accredited US schools of public health. The survey assessed the extent to which the schools were offering curriculum content in the 8 areas recommended by the Institute of Medicine: communication, community-based participatory research, cultural competence, ethics, genomics, global health, informatics, and law/policy. Findings indicated that, for the most part, schools of public health are offering content in these areas through many approaches and have incorporated various aspects of a broad-based ecological approach to public health education and training. The findings also suggested the possible need for greater content in genomics, informatics, community-based participatory research, and cultural competence. PMID:15451728

The role of the bimodal distribution of ultra-fine silicon phase and nano-scale V-phase (AlSi2Sc2) on spark plasma sintered hypereutectic Al–Si–Sc alloys

International Nuclear Information System (INIS)

Raghukiran, Nadimpalli; Kumar, Ravi

2016-01-01

Hypereutectic Al–Si and Al–Si–Sc alloys were spark plasma sintered from corresponding gas-atomized powders. The microstructures of the Al–Si and Al–Si–Sc alloys possessed remarkably refined silicon particles in the size range of 0.38–3.5 µm and 0.35–1.16 µm respectively in contrast to the silicon particles of size greater than 100 µm typically found in conventionally cast alloys. All the sintered alloys exhibited significant ductility of as high as 85% compressive strain without failure even with the presence of relatively higher weight fraction of the brittle silicon phase. Moreover, the Al–Si–Sc alloys have shown appreciable improvement in the compressive strength over their binary counterparts due to the presence of intermetallic compound AlSi 2 Sc 2 of size 10–20 nm distributed uniformly in the matrix of those alloys. The dry sliding pin-on-disc wear tests showed improvement in the wear performance of the sintered alloys with increase in silicon content in the alloys. Further, the Al–Si–Sc ternary alloys with relatively lesser silicon content exhibited appreciable improvement in the wear resistance over their binary counterparts. The Al–Si–Sc alloys with bimodal distribution of the strengthening phases consisting of ultra-fine (sub-micron size) silicon particles and the nano-scale AlSi 2 Sc 2 improved the strength and wear properties of the alloys while retaining significant amount of ductility.

LHCb's participation in LCG's Service Challenge 3 involves testing the bulk data transfer infrastructure developed to allow high bandwidth distribution of data across the grid in accordance with the computing model. To enable reliable bulk replication of data, LHCb's DIRAC system has been integrated with gLite's File Transfer Service middleware component to make use of dedicated network links between LHCb computing centres. DIRAC's Data Management tools previously allowed the replication, registration and deletion of files on the grid. For SC3 supplementary functionality has been added to allow bulk replication of data (using FTS) and efficient mass registration to the LFC replica catalog.Provisional performance results have shown that the system developed can meet the expected data replication rate required by the computing model in 2007. This paper details the experience and results of integration and utilisation of DIRAC with the SC3 transfer machinery.

The Analysis of the National Legal and Regulatory Grounds for the Institutional Autonomy of Higher Education Institutions

2017-11-01

Full Text Available The article identifies and systematizes the existing legal obstacles to the autonomy of higher education institution and develops recommendations to overcome them. The approaches to establishing the legal status of institutions of higher education in the current legislation of Ukraine are characterized. The impact of the legal status of higher education institution on its legal personality and the institutional autonomy has been determined. Views of scholars together with foreign experience of property titles in the imposition of property on higher education institution, were analyzed. Directions for the development of legal regulation of the system of public law legal entities in Ukraine have been defined. In order to ensure the development of the model of public administration in the sphere of higher education, it has been proposed that most of the higher education institutions should change the legal status of public legal entity – budgetary institution to the status of private legal entity – profitable or non-profitable higher education institution of the public / communal form of ownership, for which the founder would regularize property on the right of ownership. This will eliminate the conservatism, strict regulation on the part of the State, that is linked to the status of publicity, and, in order to develop the autonomy of higher education institution, will allow to take advantage of dispositivity inherent in private law entities in determining their legal personality.

A detailed systematic theoretical investigation of phonon and thermodynamical behavior of CuSc intermetallic compound has been carried out by uing first-principles density functional theory in B2-type (CsCl) crystal structure. Phonon dispersion curve and phonon density of states (PhDOS) are studied which confirm the stability of CuSc intermetallic compound in B2 phase. It is found that PhDOS at high frequencies mostly composed of Sc states. We have also presented some temperature dependent properties such as entropy, free energy, heat capacity, internal energy and thermal displacement, which are computed under PHONON code. The various features of these quantities are discussed in detail. From these results we demonstrate that the particular intermetallic have better ductility and larger thermal expansion.

Original Research: Use of hydroxyurea and phlebotomy in pediatric patients with hemoglobin SC disease

OpenAIRE

Summarell, Carly C Ginter; Sheehan, Vivien A

2016-01-01

Hydroxyurea is an excellent therapeutic agent for the pharmacological induction of HbF in patients with sickle cell disease (SCD). However, all completed clinical trials of hydroxyurea have excluded patients with hemoglobin SC (HbSC) disease. HbSC differs significantly in pathophysiology from HbSS, as HbC does not sickle, but instead causes cellular dehydration which potentiates sickling of HbS. Many severely affected HbSC patients have been placed on hydroxyurea on a case by case basis, but ...

First-principles study of the nucleation and stability of ordered precipitates in ternary Al-Sc-Li alloys

International Nuclear Information System (INIS)

Mao, Z.; Chen, W.; Seidman, D.N.; Wolverton, C.

2011-01-01

First-principles density functional calculations are used to study the nucleation and stability of L1 2 -ordered precipitates in Al-Sc-Li alloys. For dilute Al alloys, there are three possible ordered L1 2 precipitates: Al 3 Sc, Al 3 Li and an Al 3 Sc/Al 3 Li core/shell structure. To calculate the nucleation behavior, information about bulk thermodynamics (both static total energies and vibrational free energies), interfacial energetics and coherency strain is required. The study finds the following: (1) the coherency strain energies for forming coherent interfaces between Al/Al 3 Sc, Al/Al 3 Li and Al 3 Sc/Al 3 Li are relatively small, owing to the small atomic size mismatches in these systems; (2) the sublattice site preferences of Sc and Li are calculated, and it is demonstrated that Sc and Li share the same sublattice sites in both Al 3 Sc(L1 2 ) and Al 3 Li(L1 2 ), in agreement with recent experimental results; (3) the calculated solubilities of Sc and Li in α-Al alloys are in good agreement with experimental values and, for Sc, agree well with prior first-principles results; (4) the interfacial energies for Al/Al 3 Sc, Al/Al 3 Li and Al 3 Sc/Al 3 Li for (1 0 0), (1 1 0) and (1 1 1) interfaces are calculated: the values of the Al/Al 3 Sc interfacial energies are significantly larger than those of the Al/Al 3 Li and Al 3 Sc/Al 3 Li interfaces; (5) combining the bulk and interfacial energies yields the nucleation barriers and critical radii for Al 3 Sc and Al 3 Li precipitates; and (6) the energetic stability of the Al 3 Sc/Al 3 Li core/shell structure is compared with individual Al 3 Sc and Al 3 Li nuclei, and the range of precipitate sizes for which the core/shell structure is energetically favored is determined quantitatively.

Full Text Available Nowadays in Romania, projects financed from nonrefundable external funds post-accession are an important additional source of funding for public institutions of academic education in the somber context of the budgetary underfunding and under the significant decrease in the number of the students that are paying tuition fees. In these circumstances, this paper focuses on the accounting codification and instrumentation of the operations afferent to the projects financed from structural funds, materializing into a pragmatic approach in which we aim to present the accounting reflection of the specific accounting operations in the case of the University of Craiova, as public beneficiary of post-accession external grants, based on the principle of expenses reimbursement. In order to achieve our desideration, we shall consider issues related to the interpretation of the applicable referential in full correlation with the practice size in the context of the accounting capitalization of the financial allocations facilitated by the contracts signed between the public institutions of higher education and the pan-European financier.

A novel kind of SC (superconducting) solenoid coil is designed to satisfy the homogeneity requirement of the magnetic field. In this paper, we first calculate the current density distribution of the solenoid coil section through the linear programming method. Then a traditional solenoid and a nonrectangular section solenoid are designed to produce a central field up to 7 T with a homogeneity to the greatest extent. After comparison of the two solenoid coils designed in magnet field quality, fabrication cost and other aspects, the new design of the nonrectangular section of a solenoid coil can be realized through improving the techniques of framework fabrication and winding. Finally, the outlook and error analysis of this kind of SC magnet coil are also discussed briefly. (authors)

Are political institutions resistant to changes?

Directory of Open Access Journals (Sweden)

Vranić Bojan

2012-01-01

Full Text Available To what extent is the New institutionalism capable of explaining why implementations of public policies in political institutions may engender resistance? The author believes that political institutions are endogenous and not exogenous entities. The author first tries to demonstrate what constitutes the autonomy of a political institution by recognizing the elements of a specific political culture which becomes source of formation of political identities to political actors. Subsequently, the author examines the assumption that a political institution and actors are not tolerant to public policies authoritatively imposed from the exterior. The result of this collision is the resistance of a political institution. In the end, the author analyzes certain possible forms of resistance and their effect on preventing the implementation of public policy.

Yamamoto, S.; Taguchi, S.; Watanabe, I.; Kawase, S.

1987-01-01

An impregnated cathode of a novel structure is proposed, fabricated, and evaluated. A thin tungsten film 100--400 nm in thickness containing various amounts of Sc 2 O 3 is coated on a standard impregnated cathode composed of a porous tungsten body in which electron emissive materials are impregnated. The electron emission property measured with a diode configuration is found to be dependent on Sc 2 O 3 content and surface atom distribution. Surface atom distribution is depicted by means of Auger electron spectroscopy. For high electron emission enhancement it is necessary for Sc 2 O 3 content to be 2.5--6.5 wt. % and for a layer of the order of a monolayer in thickness composed of Ba, Sc, and O to develop on the cathode surface

BOOK REVIEW: Assessing Sc1 for GCSE

Science.gov (United States)

Reynolds, H.

2000-01-01

It is well known that investigations that `fit' the National Curriculum or examination board criteria are few in number. The fair testing emphasis means that pupils all over the country are finding out what affects the rate of a chemical reaction, the rate of photosynthesis or, in the case of Physics, the resistance of a wire. This book focuses on nine of the most common Sc1 investigations and how to prepare for them, manage and assess them. The author, a GCSE examiner, has turned his expertise into a handbook for improving Sc1 performance in the classroom. He has produced a book that would be extremely useful to both newly qualified teachers and experienced teachers. The first aim of the book, however, is to explain the requirements of Sc1. This is done comprehensively with examples of what the jargon means in practice. By breaking down the elements of planning, obtaining evidence, analysing evidence and evaluating, it is easy to see the subtleties of the mark descriptors. At first glance there seems to be little difference between the type of scientific knowledge needed for planning at level 6 and level 8. However, the level 8 statement specifies `detailed' scientific knowledge and understanding, which would mean a student should use equations from physics or symbolic chemical equations to support their arguments. One of the most useful sections in the book details the marking problems that can arise with some investigations. For example, in an investigation into electromagnets it is difficult for students to provide sufficient relevant scientific theory to satisfy the requirements of planning at level 6. One of the problems with Sc1 is that certain requirements, such as graph plotting, are difficult for many students. This book provides exercises that can be given to students to improve those skills. Each of the nine investigations is covered in great detail. Each investigation begins with an introduction detailing the rationale for choosing it, whether students

2012-01-01

Aim: In the present study we demonstrate the in vitro and in vivo comparison of the 44 Sc and 68 Ga labeled DOTA-BN[2-14]NH 2 . 44 Sc is a positron emitter with a half life of 3.92 h. Hence it could be used for PET imaging with ligands requiring longer observation time than in the case of 68 Ga. Methods: The binding affinity of nat Sc-DOTA-BN[2-14]NH 2 and nat Ga-DOTA-BN[2-14]NH 2 to GRP receptors was studied in competition to [ 125 I-Tyr 4 ]-Bombesin in the human prostate cancer cell line PC-3. A preliminary biodistribution in normal rats was performed, while first microPET images were assessed in male Copenhagen rats bearing the androgen-independent Dunning R-3327-AT-1 prostate cancer tumor. Results: The affinity to GRP receptors in the PC-3 cell line was higher for nat Ga-DOTA-BN[2-14]NH 2 (IC 50 (nM)=0.85±0.06) than that of nat Sc-DOTA-BN[2-14]NH 2 (IC 50 (nM)=6.49±0.13). The internalization rate of 68 Ga labeled DOTA-BN[2-14]NH 2 was slower than that of 44 Sc, but their final internalization percents were comparable. 68 Ga-DOTA-BN[2-14]NH 2 was externalized faster than 44 Sc-DOTA-BN[2-14]NH 2 . The biodistribution of 44 Sc-DOTA-BN[2-14]NH 2 and 68 Ga-DOTA-BN[2-14]NH 2 in normal rats revealed a higher uptake in target organs and tissues of the first one while both excreted mainly through urinary tract. In microPET images both tracers were accumulated in the tumor with similar uptake patterns. Conclusions: Despite the differences in the receptor affinity both the 68 Ga- and the 44 Sc-labeled DOTA-BN[2-14]NH 2 tracers showed comparable distribution and similar time constants of uptake and elimination. Moreover no differences in tumor accumulation (neither in the overall uptake nor in the dynamics) were observed from the microPet imaging. From that perspective the use of either 44 Sc or 68 Ga for detecting tumors with GRP receptors is equivalent. - Highlights: ► In vitro and in vivo evaluation of 44 Sc- and 68 Ga-DOTA-BN[2-14]NH 2 in reference to published

Radionuclides with medium energy beta emission and a several day half-life are attractive candidates for radioimmunotherapy. Among the most promising in this category is {sup 47}Sc produced by fast neutron irradiation (E{sub n} > 1 MeV) of titanium target with high energy neutrons in {sup 47}Ti(n,p){sup 47}Sc nuclear reaction. In the previously reported production scheme the dissolution of the TiO{sub 2} target in hot concentrated H{sub 2}SO{sub 4} and evaporation of the resulting solution were the most time-consuming steps. The present paper describes new, simple and efficient production method of {sup 47}Sc, where the slow dissolution of the target is avoided. After irradiation in fast neutron flux {sup 47}TiO{sub 2} and Li{sub 2}{sup 47}TiF{sub 6} targets were dissolved in HF solutions. Next {sup 47}Sc was separated from the target using anion exchange resin Dowex 1 with 0.4 M HF + 0.06 M HNO{sub 3} solution as eluent. The eluted {sup 47}Sc was adsorbed on cation exchange resin and eluted with 0.5 M of ammonium acetate. The 47Sc separation yield in the proposed procedure is about 90% with the separation time less than 2 h. The obtained no-carrier-added {sup 47}Sc was used to label DOTATATE conjugate with 96% labeling yield. (orig.)

High hardness TiAlN alloys for wear-resistant coatings exhibit limited lifetimes at elevated temperatures due to a cubic-AlN to hexagonal-AlN phase transformation that leads to decreasing hardness. We enhance the hardness (up to 46 GPa) and maximum operating temperature (up to 1050 °C) of TiAlN-based coatings by alloying with scandium nitride to form both an epitaxial TiAlScN alloy film and epitaxial rocksalt TiN/(Al,Sc)N superlattices on MgO substrates. The superlattice hardness increases with decreasing period thickness, which is understood by the Orowan bowing mechanism of the confined layer slip model. These results make them worthy of additional research for industrial coating applications.

Recently, we found that a Mg-Sc alloy with a bcc (β) phase exhibits superelasticity and a shape memory effect at low temperature. In this work, we examined the stress-induced and thermally induced martensitic transformation of the β-type Mg-Sc alloy and investigated the crystal structure of the thermally induced martensite phase based on in situ X-ray diffraction (XRD) measurements. The lattice constants of the martensite phase were calculated to be a = 0.3285 nm, b = 0.5544 nm, and c = 0.5223 nm when we assumed that the martensite phase has an orthorhombic structure (Cmcm). Based on the lattice correspondence between a bcc and an orthorhombic structures such as that in the case of β-Ti shape memory alloys, we estimated the transformation strain of the β Mg-Sc alloy. As a result, the transformation strains along the 001, 011, and 111 directions in the β phase were calculated to be + 5.7, + 8.8, and + 3.3%, respectively.

SC(Steel plate Concrete) module method uses steel plate instead of reinforcing bar and mold in existing RC structure. Steel plate modules are fabricated in advance, installed and poured with concrete in construction field, so construction period is remarkably shortened by SC module technique. In case of existence of temperature gap between internal and external structure surface such as spent fuel storage pool, thermal stress is taken place and as a result of it, structural strength is deteriorated. In this study, we designed three test specimens and several tests with or without temperature heating were conducted to evaluate temperature behavior of SC structures under pure bending loading condition

Transport of one SC coil through the village of Meyrin

CERN Multimedia

1956-01-01

In 1952, before CERN was officially founded, two accelerator projects were launched: one for an innovative accelerator to operate at an energy level unequalled at the time, the other for a more standard machine, a Synchro-Cyclotron (SC) to operate at 600 MeV. Design work on the SC was started in 1952 and carried out by teams scattered throughout Europe. Once construction began in 1954, CERN had to arrange road transport for the first of what has since been a long series of spectacular component deliveries, such as those of the machine's two magnetic coils each weighing 60 tonnes and measuring 7.2 metres in diameter. Above, one of them is seen passing through the village of Meyrin. The SC was commissioned in 1957 and was operational for 34 years!

Monthly grids of the self-calibrating Palmer Drought Severity Index (Sc-PDSI) have been calculated for the period 1961-2010 for the Carpathian Region (17˚-27˚E, 44˚-50˚N) with a spatial resolution of 0.1˚x 0.1˚. Using the Sc-PDSI and the assumptions of the Palmer Drought Model (PDM), the approximated precipitation required for drought termination (achieved when the Sc-PDSI turns back above -0.5) and amelioration (achieved when the Sc-PDSI value turns back above -2.0) are computed for periods of 1, 3, 6, and 9 months. The Sc-PDSI is based on a modified version of the Palmer Drought Severity Index (PDSI), first introduced by Palmer (1965) with the intent to measure the cumulative departure (related to local normal conditions) of moisture supply and demand. Due to its empirically derived climatic characteristic (K) and duration factors - limited to U.S. climatic conditions - Wells et al. (2004) improved it and transformed the PDSI into the Sc-PDSI, which is more appropriate for spatial comparisons in different climatic regions. The Sc-PDSI is based on the supply-and-demand concept of a complex water budget system based on precipitation and temperature records and also on the soil characteristics at any location. The inputs used in this study are the Available Water Capacity of the soil (AWC) derived from the soil texture (European Soil Database of JRC) with a spatial resolution of 0.1˚x0.1˚, Potential Evapo-Transpiration (PET), and 6 hydrological parameters of the soil water balance: recharge, runoff, loss, and their potential values (used in the calculation of Palmer's constants to define the normal climate for the specific location, i.e. the so called CAFEC). PET has been computed using the 0.1˚x 0.1˚ gridded monthly precipitation and mean temperature for 1961-2010 provided by the CARPATCLIM project in the framework of the construction of a Climate Atlas for the Carpathian Region. The Sc-PDSI focuses on the monthly anomalies of the soil moisture, thus it

L-Arginine ethylester enhances in vitro amplification of PrP(Sc) in macaques with atypical L-type bovine spongiform encephalopathy and enables presymptomatic detection of PrP(Sc) in the bodily fluids.

Protease-resistant, misfolded isoforms (PrP(Sc)) of a normal cellular prion protein (PrP(C)) in the bodily fluids, including blood, urine, and saliva, are expected to be useful diagnostic markers of prion diseases, and nonhuman primate models are suited for performing valid diagnostic tests for human Creutzfeldt-Jakob disease (CJD). We developed an effective amplification method for PrP(Sc) derived from macaques infected with the atypical L-type bovine spongiform encephalopathy (L-BSE) prion by using mouse brain homogenate as a substrate in the presence of polyanions and L-arginine ethylester. This method was highly sensitive and detected PrP(Sc) in infected brain homogenate diluted up to 10(10) by sequential amplification. This method in combination with PrP(Sc) precipitation by sodium phosphotungstic acid is capable of amplifying very small amounts of PrP(Sc) contained in the cerebrospinal fluid (CSF), saliva, urine, and plasma of macaques that have been intracerebrally inoculated with the L-BSE prion. Furthermore, PrP(Sc) was detectable in the saliva or urine samples as well as CSF samples obtained at the preclinical phases of the disease. Thus, our novel method may be useful for furthering the understanding of bodily fluid leakage of PrP(Sc) in nonhuman primate models. Copyright © 2016 Elsevier Inc. All rights reserved.

Three-dimensional electron backscatter diffraction, focused ion beam, transmission electron microscopy and energy filtered transmission electron microscopy were employed to investigate the structural information of primary Al{sub 3}(Sc,Zr) phase, i.e. size, shape, element distribution and orientation relationship with the α-Al matrix. It was found that (i) most primary Al{sub 3}(Sc,Zr) phases have a cubic three-dimensional morphology, with a size of about 6–10 μm, (ii) most primary Al{sub 3}(Sc,Zr) phases are located within the α-Al matrix, and exhibit a cube to cube orientation relationship with the α-Al matrix, and (iii) a layer by layer growth was observed within primary Al{sub 3}(Sc,Zr) phases. Al, Cu, Si and Fe are enriched in the α-Al matrix between the layers of cellular eutectic Al{sub 3}(Sc,Zr) phase, while Sc, Ti and Zr are enriched in small Al{sub 3}(Sc,Zr) phases. A peritectic reaction and subsequent eutectic reaction between Al{sub 3}Sc and Al was proposed to interpret the observed layer by layer growth. This paper demonstrates that the presence of impurities (Fe, Si, Cu, Ti) in the diffusion field surrounding the growing Al{sub 3}(Sc,Zr) particle enhances the heterogeneous nucleation of Al{sub 3}(Sc,Zr) phases. - Highlights: • Most fine cubic primary Al{sub 3}(Sc,Zr) phases were observed within the α-Al matrix. • A layer by layer growth within primary Al{sub 3}(Sc,Zr) phase was observed. • A peritectic and subsequent eutectic reaction between Al{sub 3}Sc and Al was proposed. • Impurities in diffusion fields enhance heterogeneous nucleation of Al{sub 3}(Sc,Zr)

Trivalent lanthanide ions (Ln(3+))-doped inorganic nanoparticles (NPs) as potential luminescent bioprobes have been attracting tremendous interest because of their unique upconversion (UC) and downconversion (DC) luminescence properties. NaScF4, as an important host material, has been rarely reported and its crystal structure remains unclear. Herein, based on the single crystal X-ray diffraction, the space group of NaScF4 crystals was determined to be P31 containing multiple sites of Sc(3+) with crystallographic site symmetry of C1, which was verified by high-resolution photoluminescence spectroscopy of Eu(3+) at low temperature (10 K). Furthermore, monodisperse and size-controllable NaScF4:Ln(3+) NPs were synthesized via a facile thermal decomposition method. The biotinylated NaScF4:Er(3+)/Yb(3+) NPs were demonstrated for their applications as a heterogeneous UC luminescence bioprobe to detect avidin with a detection limit of 180 pM. After bioconjugation with amino-terminal fragment (ATF) of urokinase plasminogen activator (uPA), NaScF4:Ln(3+) NPs also exhibited specific recognition of cancer cells overexpressed with uPA receptor (uPAR, an important marker of tumor biology and metastasis), showing great potentials in tumor-targeted bioimaging.

) orientation. The crystal structure, morphology, thermal conductivity, and thermoelectric and electrical properties were investigated. The ScN reference film exhibited a Seebeck coefficient of −45 μV/K and a power factor of 6 × 10−4 W/m K2 at 750 K. Estimated from room temperature Hall measurements, all...... samples exhibit a high carrier density of the order of 1021 cm−3. Inclusion of heavy transition metals into ScN enables the reduction in thermal conductivity by an increase in phonon scattering. The Nb inserted ScN thin films exhibited a thermal conductivity lower than the value of the ScN reference (10.......5 W m−1 K−1) down to a minimum value of 2.2 Wm−1 K−1. Insertion of Nb into ScN thus resulted in a reduction in thermal conductivity by a factor of ∼5 due to the mass contrast in ScN, which increases the phonon scattering in the material....

Highlights: • Ability of CFD to predict the performance of a sc-CO_2 test compressor is shown. • Risk of vapor pockets occurrence inside a scale 1:1 compressor is highlighted. • Limitation of previous performance maps approaches to model the real gas behavior is shown. • A performance maps approach for the sc-CO_2 compressor is proposed and validated. - Abstract: One of the challenges in the performance prediction of the supercritical CO_2 (sc-CO_2) compressor is the real gas behavior of the working fluid near the critical point. This study deals with the establishment of an approach that allows coping with this particularity by dressing compressor performance maps in adequate reduced coordinates (i.e., suitable dimensionless speed and flow parameters inputs and pressure ratio and enthalpy rise outputs), while using CFD for its validation. Two centrifugal compressor designs have been considered in this work. The first one corresponds to a 6 kW small scale component implemented in a test loop at Tokyo Institute of Technology. The second one corresponds to a 38 MW scale 1:1 design considered at an early stage of a project that investigates sc-CO_2 cycle for a Small Modular Reactor application. Numerical results on the former have been successfully confronted with the experimental data to qualify the ability of CFD to provide a performance database. Results on the latter have revealed a significant decrease in the static temperature and pressure during flow acceleration along the leading edge of the impeller blades. In this line, the increased risk of vapor pockets appearance inside a sc-CO_2 compressor has been highlighted and recommendations regarding the choice of the on-design inlet conditions and the compressor design have been given to overcome this concern. CFD results on the scale 1:1 compressor have then been used to evaluate the relevancy of some previous performance maps approaches for a sc-CO_2 compressor application. These include the conventional

Coumarin, coumarin derivatives and coumarin complex compounds known to possess biological activities such as anticancer and antiviral. The reaction between the active compound coumarin derivatives with radioisotopes Sc-46 is expected to give a complex that will be marked for further investigation of its biological activity in purpose of drug development based on coumarin. This study aims to determine the optimum conditions in the synthesis of its complex compounds as well as the physico chemical characteristics including physical properties and radiochemical purity of the complex. 3.3 benzilidene bis [4-hydroxycoumarin] ligand has successfully synthesized by reacting 4-hydroxycoumarin with benzaldehyde. Complex solids formed instantly when the solution ScCl 3 labeled by Sc-46 with a pH of 5 is reacted with a ligand solution with a pH of 11 with the optimum ratio of Sc: ligand were 1:2 with optimum labeling percentage of 99,75 ± 0,02%. FTIR analysis of complex compounds and ligands show some shift in absorption due to the formation of complex. Melting point of ligand was 234°C whilst complex compound was not yet melted in maximum range of Fischer-Jons instrument at 300°C. The complex was white reddish coloured and well soluble in DMSO. Radiochemical purity of the complex Sc-(3,3 benzilidene bis [4-hydroxycoumarin]) 2 .2H 2 O was 91.22%. Complex compound of coumarin labeled by Sc-46 has been successfully synthesized and characterized with proposed molecular formula of Sc-(3,3 benzilidene bis [4-hydroxycoumarin]) 2 .2H 2 O. (author)

V/Sc multilayer is experimentally demonstrated for the first time as a high reflectance mirror for the soft X-ray water window region. It primarily works at above the Sc-L edge (λ = 3.11 nm) under near normal incidence while a second peak appears at above the V-L edge (λ = 2.42 nm) under grazing incidence. The V/Sc multilayer fabricated with a d-spacing of 1.59 nm and 30 bilayers has a smaller interface width (σ = 0.27 and 0.32 nm) than the conventional used Cr/Sc (σ = 0.28 and 0.47 nm). For V/Sc multilayer with 30 bilayers, the introduction of B 4 C barrier layers has little improvement on the interface structure. As the number of bilayers increasing to 400, the growth morphology and microstructure of the V/Sc layers evolves with slightly increased crystallization. Nevertheless, the surface roughness remains to be 0.25 nm. A maximum soft X-ray reflectance of 18.4% is measured at λ = 3.129 nm at 9° off-normal incidence using the 400-bilayers V/Sc multilayer. According to the fitted model, an s-polarization reflectance of 5.2% can also be expected at λ = 2.425 nm under 40° incidence. Based on the promising experimental results, further improvement of the reflectance can be achieved by using a more stable deposition system, exploring different interface engineering methods and so on.

Full Text Available In this article a new Transformer and Switched Capacitor-based Boost Converter (T & SC-BC is proposed for high-voltage/low-current renewable energy applications. The proposed T & SC-BC is an original extension for DC-DC boost converter which is designed by utilizing a transformer and switched capacitor (T & SC. Photovoltaic (PV energy is a fast emergent segment among the renewable energy systems. The proposed T & SC-BC combines the features of the conventional boost converter and T & SC to achieve a high voltage conversion ratio. A Maximum Power Point Tracking (MPPT controller is compulsory and necessary in a PV system to extract maximum power. Thus, a photovoltaic MPPT control mechanism also articulated for the proposed T & SC-BC. The voltage conversion ratio (Vo/Vin of proposed converter is (1 + k/(1 − D where, k is the turns ratio of the transformer and D is the duty cycle (thus, the converter provides 9.26, 13.88, 50/3 voltage conversion ratios at 78.4 duty cycle with k = 1, 2, 2.6, respectively. The conspicuous features of proposed T & SC-BC are: (i a high voltage conversion ratio (Vo/Vin; (ii continuous input current (Iin; (iii single switch topology; (iv single input source; (v low drain to source voltage (VDS rating of control switch; (vi a single inductor and a single untapped transformer are used. Moreover, the proposed T & SC-BC topology was compared with recently addressed DC-DC converters in terms of number of components, cost, voltage conversion ratio, ripples, efficiency and power range. Simulation and experimental results are provided which validate the functionality, design and concept of the proposed approach.

Ferromagnetism carried by highly delocalized hybrid states in Sc-doped ZnO thin films

KAUST Repository

Benali Kanoun, Mohammed

2012-05-29

We present first-principles results for Sc-doped ZnOthin films. Neighboring Sc atoms in the surface and/or subsurface layers are found to be coupled ferromagnetically, where only two of the possible configurations induce spin polarization. In the first configuration, the polarization is carried by the Sc d states as expected for transition metaldoping. However, there is a second configuration which is energetically favorable. It is governed by polarized hybrid states of the Zns, O p, and Sc d orbitals. Such highly delocalized states can be an important ingredient for understanding the magnetism of dopedZnOthin films.

The logical underpinnings and benefits of pooled pharmaceutical procurement: a pragmatic role for our public institutions?

Science.gov (United States)

Multi-national pharmaceutical companies have long operated across national boundaries, and exercised significant leverage because of the breadth and depth of their market control. The goals of public health can be better served by redressing the imbalance in market leverage between supply and demand. Consolidation of purchasing power across borders, as well as within countries across organizational entities, is one means to addressing this imbalance. In those existing pooled procurement models that consolidate purchasing across national boundaries, benefits have included: 1) reductions in unit purchase prices; 2) improved quality assurance; 3) reduction or elimination of procurement corruption; 4) rationalized choice through better-informed selection and standardization; 5) reduction of operating costs and administrative burden; 6) increased equity between members; 7) augmented practical utility in the role of the host institutions (regional or international) administering the system; and finally, 8) increased access to essential medical products within each participating country. Many barriers to implementation of a multi-country pooled procurement system are eliminated when the mechanism is established within a regional or international institution, especially where participating countries are viewed (and view themselves) as clients/members of the institution, so that they have some sense of ownership over the procurement mechanism. This review article is based on two literature reviews, conducted between 2007 and 2009 (including publications from 1996 through 2009), and interviews with key informants.

To obtain information of (p,n) reaction of heavy nucleus in 100 MeV or less, 42,44,48 Ca(p,n) 42,44,48 Sc was observed on the Cyclotron Radio Isotope Center in Tohoku University. The experimental results showed that 7, 8 and 10 spin parities were determined for 42 Sc, 44 Sc and 48 SC, respectively. It was the first determination of one and two negative parity transition of 42 Sc and 48 Sc,respectively, by (p,n) reaction. The full space wave function made by 0f1p shell effective interaction by Richter,et al is good accuracy and reliability. On the (p,n) reaction at E p =35 MeV, the transition matrix elements of 42 Ca, 44 Ca and 48 Ca were derived. On the experiment of 42 Ca(p,n) 42 Sc at E p 2 on energy was agreed with the calculation results by Franey and Love. The nuclear structure of 42 Ca was thought to show more stronger U(4) symmetry, because strong GT transition at T=1 was not observed, which was expected by j-j bonding shell model calculation.

Experimental investigations of crystal structure, magnetism and heat capacity of compounds in the pseudoternary GdScGe-GdScSb system combined with density functional theory projections have been employed to clarify the interplay between the crystal structure and magnetism in this series of RTX materials (R  =  rare-earth, T   =  transition metal and X  =  p-block element). We demonstrate that the CeScSi-type structure adopted by GdScGe and CeFeSi-type structure adopted by GdScSb coexist over a limited range of compositions 0.65 ≤slant x ≤slant 0.9 . Antimony for Ge substitutions in GdScGe result in an anisotropic expansion of the unit cell of the parent that is most pronounced along the c axis. We believe that such expansion acts as the driving force for the instability of the double layer CeScSi-type structure of the parent germanide. Extensive, yet limited Sb substitutions 0 ≤slant x disappearance of the induced magnetic moments on Sc. For the parent antimonide, heat capacity measurements indicate an additional transition below the main antiferromagnetic transition.

Single chain variable fragment (scFv) antibody libraries are widely used for developing novel bioaffinity reagents, although Fab or IgG molecules are the preferred antibody formats in many final applications. Therefore, rapid conversion methods for combining multiple DNA fragments are needed to attach constant domains to the scFv derived variable domains. In this study we describe a fast and easy cloning method for the conversion of single framework scFv fragments to Fab fragments using type IIS restriction enzymes. All cloning steps excluding plating of the Fab transformants can be done in 96 well plates and the procedure can be completed in one working day. The concept was tested by converting 69 scFv clones into Fab format on 96 well plates, which resulted in 93% success rate. The method is particularly useful as a high-throughput tool for the conversion of the chosen scFv clones into Fab molecules in order to analyze them as early as possible, as the conversion can significantly affect the binding properties of the chosen clones.

The isomeric and β-decay properties of neutron-rich 53-57 Sc and 53,54 Ca nuclei near neutron number N=32 are reported, and the low-energy level schemes of 53,54,56 Sc and 53-57 Ti are presented. The low-energy level structures of the 21 Sc isotopes are discussed in terms of the coupling of the valence 1f 7/2 proton to states in the corresponding 20 Ca cores. Implications with respect to the robustness of the N=32 subshell closure are discussed, as well as the repercussions for a possible N=34 subshell closure.

Investigating the local structure of B-site cations in (1-x)BaTiO3-xBiScO3 and (1-x)PbTiO3-xBiScO3 using X-ray absorption spectroscopy

The structural properties of (1-x)BaTiO3-xBiScO3 and (1-x)PbTiO3-xBiScO3 were investigated using powder X-ray diffraction and X-ray absorption spectroscopy. Diffraction measurements confirmed that substituting small amounts of BiScO3 into BaTiO3 initially stabilizes a cubic phase at x = 0.2 before impurity phases begin to form at x = 0.5. BiScO3 substitution also resulted in noticeable changes in the local coordination environment of Ti4+. X-ray absorption near-edge spectroscopy (XANES) analysis showed that replacing Ti4+ with Sc3+ results in an increase in the off-centre displacement of Ti4+ cations. Surprisingly, BiScO3 substitution has no effect on the displacement of the Ti4+ cation in the (1-x)PbTiO3-xBiScO3 solid solution.

A severely growth retarded baby was born at 38 weeks gestation. He had multiple craniofacial anomalies, microbrachycephaly, phocomelia in the upper limbs and renal cysts visible on ultrasound. He died of recurrent apneas. The autopsy showed left sided multicystic dysplastic kidney and absence of one testis. Cytogenetic studies did not reveal any abnormality. The phenotypic features match those described in the Roberts-SC phocomelia syndrome. A literature review revealed that 50% of these patients have chromosomal defects and antenatal detection is possible on ultrasound and by chromosome analysis of the amniocytes.

Original Research: Use of hydroxyurea and phlebotomy in pediatric patients with hemoglobin SC disease.

Hydroxyurea is an excellent therapeutic agent for the pharmacological induction of HbF in patients with sickle cell disease (SCD). However, all completed clinical trials of hydroxyurea have excluded patients with hemoglobin SC (HbSC) disease. HbSC differs significantly in pathophysiology from HbSS, as HbC does not sickle, but instead causes cellular dehydration which potentiates sickling of HbS. Many severely affected HbSC patients have been placed on hydroxyurea on a case by case basis, but there are no large scale prospective data on safety or efficacy of hydroxyurea in this subset of patients with SCD. Here, we report a case series of 14 pediatric patients with HbSC treated to maximum tolerated dose (MTD) with hydroxyurea. Those who failed to show clinical improvement after at least six months at MTD were offered phlebotomy in addition to hydroxyurea. Five out of 11 patients with HbSC who achieved MTD failed to demonstrate clinical improvement on hydroxyurea. Of the four placed on dual hydroxyurea and phlebotomy therapy, all showed at least partial clinical improvement. Percent dense red blood cells (%DRBC) were measured via an ADVIA hematology analyzer. A marked rise in percent dense cells preceded clinical complications in three patients. Dual therapy with hydroxyurea and phlebotomy may be an effective approach to patients with HbSC that do not experience improvement with hydroxyurea alone. Monitoring of %DRBC may predict adverse events and aid in assessing hydroxyurea compliance. Large scale clinical trials are needed to evaluate the safety and efficacy of hydroxyurea and hydroxyurea with phlebotomy in patients with HbSC disease. © 2016 by the Society for Experimental Biology and Medicine.

This paper reflects the partial results of a Master degree research, performed in IPEN and CTMSP in Brazil. The focus of this research is to establish the best practices for an Institutional Performance Indicators System in Public Research, Development and Innovation (R and D and I) Organizations, particularly, the military ones. In public sector, especially military Institutes that are strongly committed to R and D and I, there have been changes in order to modernize the organization management. The focus, in our days, is on the Performance Indicator System, financial or not, strategic, tactic and operational, as a tool for the organizational control over the accomplishment of settled plans, the completion of the mission, everything according to a continuous improvement process. Among the many approaches underlying the development of a Performance Indicator System, since the 90s, the Balanced Scorecard - BSC stands out. It is based on the studies developed by Kaplan and Norton in 1986. By using the BSC approach, it is possible to construct a Performance Indicator System that makes available the information, financial or non-financial data, in logical format. This paper presents the results of the international and national experiences review of Institutional Performance Indicator Systems, applicable to the public organizations of R and D and I, preferably military organizations, and identify the best practices of these Systems.
