    2016-01-01

    The Advanced Stirling Convertor (ASC) development effort was initiated by NASA Glenn Research Center with contractor Sunpower, Inc., to develop high-efficiency thermal-to-electric power conversion technology for NASA Radioisotope Power Systems (RPSs). Early successful performance demonstrations led to the expansion of the project as well as adoption of the technology by the Department of Energy (DOE) and system integration contractor Lockheed Martin Space Systems Company as part of the Advanced Stirling Radioisotope Generator (ASRG) flight project. The ASRG integrates a pair of ASCs to convert the heat from a pair of General Purpose Heat Source (GPHS) modules into electrical power. The expanded NASA ASC effort included development of several generations of ASC prototypes or engineering units to help prepare the ASC technology and Sunpower for flight implementation. Sunpower later had two parallel contracts allowing the last of the NASA engineering units called ASC-E3 to serve as pathfinders for the ASC-F flight convertors being built for DOE. The ASC-E3 convertors utilized the ASC-F flight specifications and were built using the ASC-F design and process documentation. Shortly after the first ASC-F pair achieved initial operation, due to budget constraints, the DOE ASRG flight development contract was terminated. NASA continues to invest in the development of Stirling RPS technology including continued production of the ASC-E3 convertors, seven of which have been delivered with one additional unit in production. Starting in fiscal year 2015, Stirling Convertor Technology Maturation has been reorganized as an element of the RPS Stirling Cycle Technology Development (SCTD) Project and long-term plans for continued Stirling technology advancement are in reformulation. This paper provides a status on the ASC project, an overview of advancements made in the design and production of the ASC at Sunpower, and a summary of acceptance tests, reliability tests, and tactical

    The Advanced Stirling Convertor (ASC) is being developed by an integrated team of Sunpower and National Aeronautics and Space Administration s (NASA s) Glenn Research Center (GRC). The ASC development, funded by NASA s Science Mission Directorate, started as a technology development effort in 2003 and has since evolved through progressive convertor builds and successful testing to demonstrate high conversion efficiency, low mass, and capability to meet long-life Radioisotope Power System (RPS) requirements. The technology has been adopted by the Department of Energy and Lockheed Martin Space Systems Company s Advanced Stirling Radioisotope Generator (ASRG), which has been selected for potential flight demonstration on Discovery 12. This paper provides an overview of the status of ASC development including the most recent ASC-E2 convertors that have been delivered to GRC and an introduction to the ASC-E3 and ASC flight convertors that Sunpower will build next. The paper also describes the technology maturation and support tasks being conducted at GRC to support ASC and ASRG development in the areas of convertor and generator extended operation, high-temperature materials, heater head life assessment, organics, nondestructive inspection, spring fatigue testing, and other reliability verification tasks.

    The cover of the July 16, 1998 issue of Nature features a remarkable new "smart material" that can be used to print electronically on a variety of surfaces, including paper, plastic, and metal. The electrophoretic ink developed in J. Jacobson's lab at the Massachusetts Institute of Technology consists of liquid with dispersed, oppositely charged black and white microparticles that are contained in microcapsules. Application of a potential results in migration of the microparticles to opposite sides of the microcapsule, thereby generating either a white or black image that depends on the direction of the potential. Unlike liquid crystal displays, the image generated with electrophoretic ink is stable even after the power has been turned off. Cost and resolution of this new technology compare favorably with most other electronic image display systems currently in use or under development. Promising applications for electrophoretic ink in the future may range from street signs to electronic books (Comiskey et al., Vol. 394, pp 253-255; "News and Views" commentary by R. Wisnieff on pp 225-227).

    2012-01-01

    The Advanced Stirling Convertor (ASC) was initially developed by Sunpower, Inc. under contract to NASA Glenn Research Center (GRC) as a technology development project. The ASC technology fulfills NASA's need for high efficiency power convertors for future Radioisotope Power Systems (RPS). Early successful technology demonstrations between 2003 to 2005 eventually led to the expansion of the project including the decision in 2006 to use the ASC technology on the Advanced Stirling Radioisotope Generator (ASRG). Sunpower has delivered 22 ASC convertors of progressively mature designs to date to GRC. Currently, Sunpower with support from GRC, Lockheed Martin Space System Company (LMSSC), and the Department of Energy (DOE) is developing the flight ASC-F in parallel with the ASC-E3 pathfinders. Sunpower will deliver four pairs of ASC-E3 convertors to GRC which will be used for extended operation reliability assessment, independent validation and verification testing, system interaction tests, and to support LMSSC controller verification. The ASC-E3 and -F convertors are being built to the same design and processing documentation and the same product specification. The initial two pairs of ASC-E3 are built before the flight units and will validate design and processing changes prior to implementation on the ASC-F flight convertors. This paper provides a summary on development of the ASC technology and the status of the ASC-E3 build and how they serve the vital pathfinder role ahead of the flight build for ASRG. The ASRG is part of two of the three candidate missions being considered for selection for the Discovery 12 mission.

  7. Authenticated Secure Container System (ASCS)

    1991-01-01

    Sandia National Laboratories developed an Authenticated Secure Container System (ASCS) for the International Atomic Energy Agency (IAEA). Agency standard weights and safeguards samples can be stored in the ASCS to provide continuity of knowledge. The ASCS consists of an optically clear cover, a base containing the Authenticated Item Monitoring System (AIMS) transmitter, and the AIMS receiver unit for data collection. The ASCS will provide the Inspector with information concerning the status of the system, during a surveillance period, such as state of health, tampering attempts, and movement of the container system. The secure container is located inside a Glove Box with the receiver located remotely from the Glove Box. AIMS technology uses rf transmission from the secure container to the receiver to provide a record of state of health and tampering. The data is stored in the receiver for analysis by the Inspector during a future inspection visit. 2 refs

    2014-01-01

    Sunpower's Advanced Stirling Convertor (ASC) initiated development under contract to the NASA Glenn Research Center (GRC) and after a series of successful demonstrations, the ASC began transitioning from a technology development project to flight development project. The ASC has very high power conversion efficiency making it attractive for future Radioisotope Power Systems (RPS) in order to make best use of the low plutonium-238 fuel inventory in the U.S. In recent years, the ASC became part of the NASA-Department of Energy Advanced Stirling Radioisotope Generator (ASRG) Integrated Project. Sunpower held two parallel contracts to produce ASC convertors, one with the Department of Energy/Lockheed Martin to produce the ASC-F flight convertors, and one with NASA GRC for the production of ASC-E3 engineering units, the initial units of which served as production pathfinders. The integrated ASC technical team successfully overcame various technical challenges that led to the completion and delivery of the first two pairs of flight-like ASC-E3 by 2013. However, in late Fall 2013, the DOE initiated termination of the Lockheed Martin ASRG flight development contract driven primarily by budget constraints. NASA continues to recognize the importance of high efficiency ASC power conversion for RPS and continues investment in the technology including the continuation of ASC-E3 production at Sunpower and the assembly of the ASRG Engineering Unit #2. This paper provides a summary of ASC technical accomplishments, overview of tests at GRC, plans for continued ASC production at Sunpower, and status of Stirling technology development.

    1995-01-01

    The original version of ASCE Standard 4, ''Seismic Analysis of Safety-Related Nuclear Structures'' was published in September 1986. It is ASCE policy to update its standards on a five year interval and the Working Group on Seismic Analysis of Safety Related Nuclear Structures was reconvened to formulate the revisions. The goal in updating the standard is to make sure that it is still relevant and that it incorporates the state of the practice in seismic engineering or, in some cases, where it has been demonstrated that state-of-the-art improvements need to be made to standard practice; new improvements are included. The contents of the new standard cover the same areas as the original version, with some additions. The contents are as follows: Input - response spectra and time histories; modeling of structures; analysis of structures; soil-structure interaction; input for subsystem analysis; special structures - buried pipes and conduits, earth-retaining walls, above-ground vertical tanks, raceways, and base-isolated structures; and an appendix providing seismic probabilistic risk assessment and margin assessment

  10. Structure of AscE and Induced Burial Regions in AscE and AscG upon Formation of the Chaperone Needle-subunit Complex of Type III Secretion System in Aeromonas Hydrophila

    2008-01-01

    In the type III secretion system (T3SS) of Aeromonas hydrophila, the putative needle complex subunit AscF requires both putative chaperones AscE and AscG for formation of a ternary complex to avoid premature assembly. Here we report the crystal structure of AscE at 2.7 A resolution and the mapping of buried regions of AscE, AscG, and AscF in the AscEG and AscEFG complexes using limited protease digestion. The dimeric AscE is comprised of two helix-turn-helix monomers packed in an antiparallel fashion. The N-terminal 13 residues of AscE are buried only upon binding with AscG, but this region is found to be nonessential for the interaction. AscE functions as a monomer and can be coexpressed with AscG or with both AscG and AscF to form soluble complexes. The AscE binding region of AscG in the AscEG complex is identified to be within the N-terminal 61 residues of AscG. The exposed C-terminal substrate-binding region of AscG in the AscEG complex is induced to be buried only upon binding to AscF. However, the N-terminal 52 residues of AscF remain exposed even in the ternary AscEFG complex. On the other hand, the 35-residue C-terminal region of AscF in the complex is resistant to protease digestion in the AscEFG complex. Site-directed mutagenesis showed that two C-terminal hydrophobic residues, Ile83 and Leu84, of AscF are essential for chaperone binding.

    NASA Glenn Research Center (GRC) has been supporting development of the Advanced Stirling Radioisotope Generator (ASRG) since 2006. A key element of the ASRG project is providing life, reliability, and performance testing data of the Advanced Stirling Convertor (ASC). The latest version of the ASC (ASC-E3, to represent the third cycle of engineering model test hardware) is of a design identical to the forthcoming flight convertors. For this generation of hardware, a joint Sunpower and GRC effort was initiated to improve and standardize the test support hardware. After this effort was completed, the first pair of ASC-E3 units was produced by Sunpower and then delivered to GRC in December 2012. GRC has begun operation of these units. This process included performance verification, which examined the data from various tests to validate the convertor performance to the product specification. Other tests included detailed performance mapping that encompassed the wide range of operating conditions that will exist during a mission. These convertors were then transferred to Lockheed Martin for controller checkout testing. The results of this latest convertor performance verification activity are summarized here.

    Academic writing is a vital, yet complex skill that must be developed within a doctoral training process. In addition, becoming an academic researcher is a journey of changing sense of self and identity. Through analysis of a group session, we show how the feedback of peers addresses questions...... of structure and writing style along with wider issues of researcher identity. Thus, peer learning is demonstrated as a process of simultaneously building a text and an identity as scholarly researcher. The paper advocates ‘borrowing brainpower’ from peers in order to write better texts and, at the same time......, ‘share insecurities’ during the development of the researcher identity. Based on a distributed notion of peer learning and identity, we point to the need for further research into the everyday activities of doctoral writing groups in order to understand the dynamic relationship between production of text...

  1. The ASC Sequoia Programming Model

    Energy Technology Data Exchange (ETDEWEB)

    Seager, M

    2008-08-06

    developed with multiple 'cores' in them and called Symmetric Multi-Processor or Shared Memory Processor (SMP) systems. The parallel revolution had begun. The Laboratory started a small 'parallel processing project' in 1983 to study the new technology and its application to scientific computing with four people: Tim Axelrod, Pete Eltgroth, Paul Dubois and Mark Seager. Two years later, Eugene Brooks joined the team. This team focused on Unix and 'killer micro' SMPs. Indeed, Eugene Brooks was credited with coming up with the 'Killer Micro' term. After several generations of SMP platforms (e.g., Sequent Balance 8000 with 8 33MHz MC32032s, Allian FX8 with 8 MC68020 and FPGA based Vector Units and finally the BB&N Butterfly with 128 cores), it became apparent to us that the killer micro revolution would indeed take over Crays and that we definitely needed a new programming and systems model. The model developed by Mark Seager and Dale Nielsen focused on both the system aspects (Slide 3) and the code development aspects (Slide 4). Although now succinctly captured in two attached slides, at the time there was tremendous ferment in the research community as to what parallel programming model would emerge, dominate and survive. In addition, we wanted a model that would provide portability between platforms of a single generation but also longevity over multiple--and hopefully--many generations. Only after we developed the 'Livermore Model' and worked it out in considerable detail did it become obvious that what we came up with was the right approach. In a nutshell, the applications programming model of the Livermore Model posited that SMP parallelism would ultimately not scale indefinitely and one would have to bite the bullet and implement MPI parallelism within the Integrated Design Code (IDC). We also had a major emphasis on doing everything in a completely standards based, portable methodology with POSIX/Unix as the target

    Apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) is silenced by promoter methylation in many types of tumors, yet ASC's role in most cancers remains unknown. Here, we show that ASC is highly expressed in a model of medulloblastoma, the most common malignant pediatric brain cancer; ASC is also expressed in human medulloblastomas. Importantly, while ASC deficiency did not affect normal cerebellar development, ASC knockout mice on the Smoothened (ND2:SmoA1) transgenic model of medulloblastoma exhibited a profound reduction in medulloblastoma incidence and a delayed tumor onset. A similar decrease in tumorigenesis with ASC deficiency was also seen in the hGFAP-Cre:SmoM2 mouse model of medulloblastoma. Interestingly, hyperproliferation of the external granule layer (EGL) was comparable at P20 in both wild-type and ASC-deficient SmoA1 mice. However, while the apoptosis and differentiation markers remained unchanged at this age, proliferation makers were decreased, and the EGL was reduced in thickness and area by P60. This reduction in proliferation with ASC deficiency was also seen in isolated SmoA1 cerebellar granule precursor cells in vitro, indicating that the effect of ASC deletion on proliferation was cell autonomous. Interestingly, ASC-deficient SmoA1 cerebella exhibited disrupted expression of genes in the transforming growth factor-β pathway and increased level of nuclear Smad3. Taken together, these results demonstrate an unexpected role for ASC in Sonic hedgehog-driven medulloblastoma tumorigenesis, thus identifying ASC as a promising novel target for antitumor therapy.

    For the FY15 ASC L2 Trilab Codesign milestone Sandia National Laboratories performed two main studies. The first study investigated three topics (performance, cross-platform portability and programmer productivity) when using OpenMP directives and the RAJA and Kokkos programming models available from LLNL and SNL respectively. The focus of this first study was the LULESH mini-application developed and maintained by LLNL. In the coming sections of the report the reader will find performance comparisons (and a demonstration of portability) for a variety of mini-application implementations produced during this study with varying levels of optimization. Of note is that the implementations utilized including optimizations across a number of programming models to help ensure claims that Kokkos can provide native-class application performance are valid. The second study performed during FY15 is a performance assessment of the MiniAero mini-application developed by Sandia. This mini-application was developed by the SIERRA Thermal-Fluid team at Sandia for the purposes of learning the Kokkos programming model and so is available in only a single implementation. For this report we studied its performance and scaling on a number of machines with the intent of providing insight into potential performance issues that may be experienced when similar algorithms are deployed on the forthcoming Trinity ASC ATS platform.

    The Stockpile Stewardship Program (SSP) is an integrated technical program for maintaining the safety, surety, and reliability of the U.S. nuclear stockpile. The SSP uses nuclear test data, computational modeling and simulation, and experimental facilities to advance understanding of nuclear weapons. It includes stockpile surveillance, experimental research, development and engineering programs, and an appropriately scaled production capability to support stockpile requirements. This integrated national program requires the continued use of experimental facilities and programs, and the computational capabilities to support these programs. The Advanced Simulation and Computing Program (ASC) is a cornerstone of the SSP, providing simulation capabilities and computational resources that support annual stockpile assessment and certification, study advanced nuclear weapons design and manufacturing processes, analyze accident scenarios and weapons aging, and provide the tools to enable stockpile Life Extension Programs (LEPs) and the resolution of Significant Finding Investigations (SFIs). This requires a balance of resources, including technical staff, hardware, simulation software, and computer science solutions.

  8. Test Hardware Design for Flightlike Operation of Advanced Stirling Convertors (ASC-E3)

    Science.gov (United States)

    Oriti, Salvatore M.

    2012-01-01

    NASA Glenn Research Center (GRC) has been supporting development of the Advanced Stirling Radioisotope Generator (ASRG) since 2006. A key element of the ASRG project is providing life, reliability, and performance testing of the Advanced Stirling Convertor (ASC). For this purpose, the Thermal Energy Conversion branch at GRC has been conducting extended operation of a multitude of free-piston Stirling convertors. The goal of this effort is to generate long-term performance data (tens of thousands of hours) simultaneously on multiple units to build a life and reliability database. The test hardware for operation of these convertors was designed to permit in-air investigative testing, such as performance mapping over a range of environmental conditions. With this, there was no requirement to accurately emulate the flight hardware. For the upcoming ASC-E3 units, the decision has been made to assemble the convertors into a flight-like configuration. This means the convertors will be arranged in the dual-opposed configuration in a housing that represents the fit, form, and thermal function of the ASRG. The goal of this effort is to enable system level tests that could not be performed with the traditional test hardware at GRC. This offers the opportunity to perform these system-level tests much earlier in the ASRG flight development, as they would normally not be performed until fabrication of the qualification unit. This paper discusses the requirements, process, and results of this flight-like hardware design activity.

    Arino de la Rubia, Leigh S

    2012-09-01

    The Minority Institution Astrobiology Collaborative (MIAC) began working with the NASA Goddard Center for Astrobiology in 2003 to develop curriculum materials for high school chemistry and Earth science classes based on astrobiology concepts. The Astrobiology in Secondary Classrooms (ASC) modules emphasize interdisciplinary connections in astronomy, biology, chemistry, geoscience, physics, mathematics, and ethics through hands-on activities that address national educational standards. Field-testing of the Astrobiology in Secondary Classrooms materials occurred over three years in eight U.S. locations, each with populations that are underrepresented in the career fields of science, technology, engineering, and mathematics. Analysis of the educational research upon the high school students participating in the ASC project showed statistically significant increases in students' perceived knowledge and science reasoning. The curriculum is in its final stages, preparing for review to become a NASA educational product.

  20. External and Internal Conditionality of Language Borrowing

    Directory of Open Access Journals (Sweden)

    Лилия Михайловна Букина

    2016-12-01

    Full Text Available This article looks at the factors that condition borrowings in language. The exposure of borrowings in the language system is based on precise differentiation of intralinguistic and extralinguistic factors. The theoretical basis for this study were the works of Russian and foreign scientists (Bagana Zh., Breiter M.A., Crystal D., Kryisin L.P., et al who were interested in such diversified phenomena as borrowings, in general, and in particular the reasons for them. Research is being conducted on the basis of the French language, certain illustrative units derived empirically in the process of researching these French websites: http://www.linternaute.com, http://www.elle.fr, http://www.wuzz.fr, http://www.eurosport.fr, etc. Borrowing can occur on all levels of language, but we considered the factors that facilitate borrowing and assimilation in the recipient language of lexical borrowings. The research is aimed at considering points of view of different linguists on the problem of borrowing into the recipient language and revealing similarities and differences in the views of scientists. Notwithstanding the fact that external reasons are acting as stimuli for borrowing, there are many linguistic research works that highlight their importance in the appearance and customization of foreign words in the recipient language. Intralinguistic factors dominate in the process of adopting a foreign word into the vocabulary of another language. Psychological factors play one of the key roles in the appearance of borrowings, as language contact is performed when bilingual speakers who have separate linguistic identities communicate. During the research the following methods were used: continuous sampling method, descriptive and analytical method, method of semantic analysis, method of comparison and contrasting.

    This paper lays out a theory of taxation and public investment in an intertemporal setting under conditions of revenue shocks. Without borrowing restrictions, the optimal policy is characterized by smooth time paths of taxes and public investment. While the introduction of formal borrowing restrictions leads to some precautionary savings, it gives rise to fluctuations in public investment in response to adverse but also favorable revenue shocks. This theoretical result is tested empirically u...

    Directory of Open Access Journals (Sweden)

    Full Text Available The study of morphological assimilation is an important and mandatory problem as far as the native speaker media will be comfortable using the term of the borrowing language in the flow of speech, without considering the specific grammatical forms, largely determines its subsequent semantic assimilation, its incorporation into a particular terminology system. The analysis clearly shows the place of French borrowings in the morphological system of the Russian language, helps to identify the most significant differences between the structures of the two languages. At the same time it suggests that many French terminology borrowings morphologically assimilated fairly well, there were some groups in the Russian language, which transformed morphologically French elements falling into Russian. This makes borrowings more smooth, and loan word, provided that it actually meets the needs of the language - receptor in the host language adapts quickly and easily absorbed by native speakers

  18. The semantics of English Borrowings in Arabic Media Language: The case of Arab Gulf States Newspapers

    Directory of Open Access Journals (Sweden)

    Anwar A. H. Al-Athwary

    2016-07-01

    Full Text Available The present paper investigates the semantics of English loanwords in Arabic media language (AML. The loanword data are collected from a number of Arab Gulf states newspapers (AGSNs. They  are analyzed semantically from the points of view of semantic change, semantic domains, and the phenomenon of synonymy resulting from lexical borrowing. The semantic analysis has revealed that AML borrowings from English occur in fifteen distinctive semantic domains. Domains that are related to terms of technical and scientific nature are found ranking much higher (9% - 18% than those domains containing nontechnical elements (1% - 8% with the computer and technology category (18% is the most dominant domain. Almost all common mechanisms of semantic change (extension, restriction, amelioration, pejoration, and metaphorical extension are found at work in the context of AML borrowings. The tendency of semantic change in the overwhelming majority of AML borrowings is towards restriction.  Factors like need, semantic similarity, and factors of social and psychological considerations (e.g. prestige, taboo seem to be the potent factors at interplay in semantic change. The first two, i.e. need and semantic similarity, are the most common reasons in most types of semantic change. The problem of synonymy lies in those loanwords that have “Arabic equivalents” in the language. The study claims that this phenomenon could be attributed to the two simultaneous processes of lexical borrowing and?ištiqa:q (the modern efforts of deriving equivalent neologisms.

  19. THE BORROWER CHARACTERISTICS IN HOT EQUITY MARKETS

    Directory of Open Access Journals (Sweden)

    HALIL DINCER KAYA

    2017-06-01

    Full Text Available In this study, I examine the characteristics of U.S. corporate borrowers (public debt, private placement, and syndicated loan firms in HOT versus COLD equity markets. My main objective is to see the characteristics of firms that choose debt financing even when the equity market is HOT. HOT equity markets are defined as the top twenty percent of the months in terms of the de-trended number of equity offerings. I find that the HOT equity market borrowers generally have higher market-to-book ratios compared to the COLD market borrowers. Also, in HOT equity markets, the public debt firms (i.e. the corporate bond issuers tend to have fewer tangible assets, the private placement firms tend to be smaller and highly levered, and the syndicated loan firms tend to be smaller, more profitable, and less levered compared to the COLD market firms. When I look at the number of transactions in each market, I find that when the equity market is active (i.e. HOT, the syndicated loan market is even more active. During these periods, the public debt market is also active (although not as much as the equity or the syndicated loan markets. When I look at the sizes of the transactions in each market, I find that the private placements tend to be significantly larger in HOT markets compared to COLD markets. I conclude that while the equity, the public debt, and the syndicated loan markets move together in terms of market activity, the equity market and the private placement markets move together in terms of the size of the transaction.

  20. Studying borrower level risk characteristics of education loan in India

    Directory of Open Access Journals (Sweden)

    Arindam Bandyopadhyay

    2016-09-01

    Full Text Available This paper empirically investigates the granular level risk of education loan using a cross section of data from 5000 borrowers obtained from four major public sector banks in India. The findings suggest that education loan defaults are mainly influenced by security, borrower margin, and repayment periods. The presence of guarantor or co-borrower and collateral significantly reduce default loss rates. The socioeconomic characteristics of borrowers and their regional locations also act as important factors associated with education loan defaults. The results suggest that by segmenting borrowers by probability of default and loss given default in a multidimensional scale, banks can adopt better risk mitigation and pricing strategies to resolve borrower problems.

    Geveci, Berk (Kitware, Inc., Clifton Park, NY); Fabian, Nathan; Marion, Patrick (Kitware, Inc., Clifton Park, NY); Moreland, Kenneth D.

    2010-09-01

    This report provides documentation for the completion of the Sandia portion of the ASC Level II Visualization on the platform milestone. This ASC Level II milestone is a joint milestone between Sandia National Laboratories and Los Alamos National Laboratories. This milestone contains functionality required for performing visualization directly on a supercomputing platform, which is necessary for peta-scale visualization. Sandia's contribution concerns in-situ visualization, running a visualization in tandem with a solver. Visualization and analysis of petascale data is limited by several factors which must be addressed as ACES delivers the Cielo platform. Two primary difficulties are: (1) Performance of interactive rendering, which is most computationally intensive portion of the visualization process. For terascale platforms, commodity clusters with graphics processors(GPUs) have been used for interactive rendering. For petascale platforms, visualization and rendering may be able to run efficiently on the supercomputer platform itself. (2) I/O bandwidth, which limits how much information can be written to disk. If we simply analyze the sparse information that is saved to disk we miss the opportunity to analyze the rich information produced every timestep by the simulation. For the first issue, we are pursuing in-situ analysis, in which simulations are coupled directly with analysis libraries at runtime. This milestone will evaluate the visualization and rendering performance of current and next generation supercomputers in contrast to GPU-based visualization clusters, and evaluate the performance of common analysis libraries coupled with the simulation that analyze and write data to disk during a running simulation. This milestone will explore, evaluate and advance the maturity level of these technologies and their applicability to problems of interest to the ASC program. Scientific simulation on parallel supercomputers is traditionally performed in four

  1. A note on migration with borrowing constraints.

    Science.gov (United States)

    Ghatak, S; Levine, P

    1994-12-01

    "This note examines an important conflict between the theory and evidence on migration in LDCs. While the Harris-Todaro class of models explain the phenomenon of migration mainly by expected income differential between the economically advanced and the backward regions, the actual evidence in some cases suggests that migration could actually rise following a rise in income in backward areas. We resolve this puzzle by analysing migration in the context of the existence of imperfect credit markets in LDCs. We show that under certain plausible conditions, the rate of migration from the rural to the urban areas may actually rise when rural wages rise, as they ease the constraints on borrowing by potential migrants." excerpt

  2. Differential splicing of the apoptosis-associated speck like protein containing a caspase recruitment domain (ASC regulates inflammasomes

    2010-05-01

    Full Text Available Abstract Background The apoptotic speck-like protein containing a caspase recruitment domain (ASC is the essential adaptor protein for caspase 1 mediated interleukin (IL-1β and IL-18 processing in inflammasomes. It bridges activated Nod like receptors (NLRs, which are a family of cytosolic pattern recognition receptors of the innate immune system, with caspase 1, resulting in caspase 1 activation and subsequent processing of caspase 1 substrates. Hence, macrophages from ASC deficient mice are impaired in their ability to produce bioactive IL-1β. Furthermore, we recently showed that ASC translocates from the nucleus to the cytosol in response to inflammatory stimulation in order to promote an inflammasome response, which triggers IL-1β processing and secretion. However, the precise regulation of inflammasomes at the level of ASC is still not completely understood. In this study we identified and characterized three novel ASC isoforms for their ability to function as an inflammasome adaptor. Methods To establish the ability of ASC and ASC isoforms as functional inflammasome adaptors, IL-1β processing and secretion was investigated by ELISA in inflammasome reconstitution assays, stable expression in THP-1 and J774A1 cells, and by restoring the lack of endogenous ASC in mouse RAW264.7 macrophages. In addition, the localization of ASC and ASC isoforms was determined by immunofluorescence staining. Results The three novel ASC isoforms, ASC-b, ASC-c and ASC-d display unique and distinct capabilities to each other and to full length ASC in respect to their function as an inflammasome adaptor, with one of the isoforms even showing an inhibitory effect. Consistently, only the activating isoforms of ASC, ASC and ASC-b, co-localized with NLRP3 and caspase 1, while the inhibitory isoform ASC-c, co-localized only with caspase 1, but not with NLRP3. ASC-d did not co-localize with NLRP3 or with caspase 1 and consistently lacked the ability to function as an

    Pulmonary hypertension is a serious condition that can lead to premature death. The mechanisms involved are incompletely understood although a role for the immune system has been suggested. Inflammasomes are part of the innate immune system and consist of the effector caspase-1 and a receptor, where nucleotide-binding oligomerization domain-like receptor pyrin domain-containing 3 (NLRP3) is the best characterized and interacts with the adaptor protein apoptosis-associated speck-like protein containing a caspase-recruitment domain (ASC). To investigate whether ASC and NLRP3 inflammasome components are involved in hypoxia-induced pulmonary hypertension, we utilized mice deficient in ASC and NLRP3. Active caspase-1, IL-18, and IL-1β, which are regulated by inflammasomes, were measured in lung homogenates in wild-type (WT), ASC(-/-), and NLRP3(-/-) mice, and phenotypical changes related to pulmonary hypertension and right ventricular remodeling were characterized after hypoxic exposure. Right ventricular systolic pressure (RVSP) of ASC(-/-) mice was significantly lower than in WT exposed to hypoxia (40.8 ± 1.5 mmHg vs. 55.8 ± 2.4 mmHg, P right ventricular remodeling. RVSP of NLRP3(-/-) mice exposed to hypoxia was not significantly altered compared with WT hypoxia. Whereas hypoxia increased protein levels of caspase-1, IL-18, and IL-1β in WT and NLRP3(-/-) mice, this response was absent in ASC(-/-) mice. Moreover, ASC(-/-) mice displayed reduced muscularization and collagen deposition around arteries. In conclusion, hypoxia-induced elevated right ventricular pressure and remodeling were attenuated in mice lacking the inflammasome adaptor protein ASC, suggesting that inflammasomes play an important role in the pathogenesis of pulmonary hypertension.

    Full Text Available Aims: We aimed to investigate the immunocytoexpression profiles of a novel assay ProEx C for topoisomerase II alpha (TOP2A and minichromosome maintenance protein 2 (MCM2 in abnormal interpreted smears. Settings and Design: Screening programs with Papanicolaou smear and high risk group human papilloma virus testing have yielded a dramatic reduction of cervical cancer incidence. However, both of these tests have limited specificity for the detection of clinically significant cervical high grade lesions. ProEx C for topoisomerase II alpha (TOP2A and minichromosome maintenance protein 2 (MCM2 has been considered to have tight association with high grade intraepithelial lesions. Materials and Methods: A total number of 54 SurePath cervical cytology specimens of patients previously interpreted as atypical squamous cells-undetermined significance (ASC-US, atypical squamous cells-cannot exclude high grade squamous intraepithelial lesion (ASC-H, low grade squamous intraepithelial lesion (LSIL, and high grade squamous intraepithelial lesion (HSIL were included in our study. Results and Conclusions: ProEx C was positive in 14 of HSILs (100%, 3 of 19 LSILs (16%, 2 of 4 ASC-Hs, and none of ASC-USs (0%. The ProEx C test showed very intense nuclear staining in all cytologically abnormal cells. Further studies are indicated to evaluate the diagnostic role of ProEx C.

    Rape is considered a stressful trauma and often with durable consequences. How the aftermath of rape is for young adolescents' girls considering acute stress is an overlooked field and remains to be studied. In this study, we wanted to investigate acute stress among adolescent victims of rape and the psychometric properties of the Acute Stress Checklist for Children (ASC-Kids). A clinical sample (n = 79) of raped girls, 13-17 years old who had turned to a special rape victim unit for treatment, answered the ASC-Kids. ASC-Kids was also given to a group of minor stressed, non-raped adolescents in the same age range (n = 154) together with the University of California at Los Angeles Post-traumatic Stress Disorder Reaction Index (UCLA PTSD RI), and the Sense of Coherence Scale 13 (SOC-13). The scores from the groups were compared and showed significant differences in mean values on all the diagnostic criteria of acute stress disorder. In the clinical group, 36.7% obtained full ASD criteria. ASC-Kids could discriminate well between groups. Cronbach's alpha was found to be excellent, and the correlation between the UCLA PTSD RI and ASC-Kids found to be good; both ASC-Kids and UCLA PTSD RI had a good and moderate negative correlation with SOC-13. Adolescent female rape victims were shown to have a very high level of acute stress, and the ASC-Kids was found to have sound psychometrics and can be a valuable screening instrument to support clinicians in their assessments of an indication of adolescents after potentially stressful events such as rape.

  18. Single-Molecule Fluorescence Reveals the Oligomerization and Folding Steps Driving the Prion-like Behavior of ASC.

    Single-molecule fluorescence has the unique ability to quantify small oligomers and track conformational changes at a single-protein level. Here we tackled one of the most extreme protein behaviors, found recently in an inflammation pathway. Upon danger recognition in the cytosol, NLRP3 recruits its signaling adaptor, ASC. ASC start polymerizing in a prion-like manner and the system goes in "overdrive" by producing a single micron-sized "speck." By precisely controlling protein expression levels in an in vitro translation system, we could trigger the polymerization of ASC and mimic formation of specks in the absence of inflammasome nucleators. We utilized single-molecule spectroscopy to fully characterize prion-like behaviors and self-propagation of ASC fibrils. We next used our controlled system to monitor the conformational changes of ASC upon fibrillation. Indeed, ASC consists of a PYD and CARD domains, separated by a flexible linker. Individually, both domains have been found to form fibrils, but the structure of the polymers formed by the full-length ASC proteins remains elusive. For the first time, using single-molecule Förster resonance energy transfer, we studied the relative positions of the CARD and PYD domains of full-length ASC. An unexpectedly large conformational change occurred upon ASC fibrillation, suggesting that the CARD domain folds back onto the PYD domain. However, contradicting current models, the "prion-like" conformer was not initiated by binding of ASC to the NLRP3 platform. Rather, using a new method, hybrid between Photon Counting Histogram and Number and Brightness analysis, we showed that NLRP3 forms hexamers with self-binding affinities around 300nM. Overall our data suggest a new mechanism, where NLRP3 can initiate ASC polymerization simply by increasing the local concentration of ASC above a supercritical level. Copyright © 2017.

The conventional probabilistic mean variance model can be transformed to a linear programming problem under possibility distributions. Finally, a numerical example is given to illustrate the modeling idea and the impact of borrowing and lending on optimal decision making.

    Cartilage tissue engineering is a growing field due to the lack of regenerative capacity of native tissue. The use of bioreactors for cartilage tissue engineering is common, but the results are controversial. Some studies suggest that microgravity bioreactors are ideal for chondrogenesis, while others show that mimicking hydrostatic pressure is crucial for cartilage formation. A parallel study comparing the effects of loading and unloading on chondrogenesis has not been performed. The goal of this study was to evaluate chondrogenesis of human adipose-derived stem cells (hASC) under two different mechanical stimuli relative to static culture: microgravity and cyclic hydrostatic pressure (CHP). Pellets of hASC were cultured for 14 d under simulated microgravity using a rotating wall vessel bioreactor or under CHP (7.5 MPa, 1 Hz, 4 h · d-1) using a hydrostatic pressure vessel. We found that CHP increased mRNA expression of Aggrecan, Sox9, and Collagen II, caused a threefold increase in sulfated glycosaminoglycan production, and resulted in stronger vimentin staining intensity and organization relative to microgravity. In addition, Wnt-signaling patterns were altered in a manner that suggests that simulated microgravity decreases chondrogenic differentiation when compared to CHP. Our goal was to compare chondrogenic differentiation of hASC using a microgravity bioreactor and a hydrostatic pressure vessel, two commonly used bioreactors in cartilage tissue engineering. Our results indicate that CHP promotes hASC chondrogenesis and that microgravity may inhibit hASC chondrogenesis. Our findings further suggest that cartilage formation and regeneration might be compromised in space due to the lack of mechanical loading.Mellor LF, Steward AJ, Nordberg RC, Taylor MA, Loboa EG.

    2011-01-01

    The procedures and criteria in 2006 IBC (International Council of Building Officials, 2006) and 2007 CBC (International Council of Building Officials, 2007) for the selection and scaling ground-motions for use in nonlinear response history analysis (RHA) of structures are based on ASCE/SEI 7 provisions (ASCE, 2005, 2010). According to ASCE/SEI 7, earthquake records should be selected from events of magnitudes, fault distance, and source mechanisms that comply with the maximum considered earthquake, and then scaled so that the average value of the 5-percent-damped response spectra for the set of scaled records is not less than the design response spectrum over the period range from 0.2Tn to 1.5Tn sec (where Tn is the fundamental vibration period of the structure). If at least seven ground-motions are analyzed, the design values of engineering demand parameters (EDPs) are taken as the average of the EDPs determined from the analyses. If fewer than seven ground-motions are analyzed, the design values of EDPs are taken as the maximum values of the EDPs. ASCE/SEI 7 requires a minimum of three ground-motions. These limits on the number of records in the ASCE/SEI 7 procedure are based on engineering experience, rather than on a comprehensive evaluation. This study statistically examines the required number of records for the ASCE/SEI 7 procedure, such that the scaled records provide accurate, efficient, and consistent estimates of" true" structural responses. Based on elastic-perfectly-plastic and bilinear single-degree-of-freedom systems, the ASCE/SEI 7 scaling procedure is applied to 480 sets of ground-motions. The number of records in these sets varies from three to ten. The records in each set were selected either (i) randomly, (ii) considering their spectral shapes, or (iii) considering their spectral shapes and design spectral-acceleration value, A(Tn). As compared to benchmark (that is, "true") responses from unscaled records using a larger catalog of ground

  17. Cultural borrowing - Serbian jogurt between the east and the west

    Directory of Open Access Journals (Sweden)

    Petrović Snežana M.

    2015-01-01

    Full Text Available The paper offers an analysis of the cultural borrowing process of the Turkish word yoğurt ‘yogurt’ in Serbian. The study begins with the analysis of the Serbian lexical material from the 19th century, when the word jogurt was marked as an exclusively foreign word. The comparison with the present status of the meaning and usage of the word jogurt in contemporary Serbian, in which the word is part of the standard language, shows two different layers of the borrowing process: the Ottoman Turkish period and the Non-Turkish one. The most recent, Post-Ottoman borrowing layer is illustrated by the usage of jogurt as an element of a proverb that is a calque from the Turk. Sutten ağzı yanan yoğurdu (veya ayranı ufleyerek yer (veya icer “who gets burned by milk, blows into yogurt as well”. Aiming to present a complex process of this cultural borrowing, the data from Serbian is compared to the relevant data from other Balkan and European languages.

    Inflammasomes are multiprotein complexes that control the innate immune response by activating caspase-1, thus promoting the secretion of cytokines in response to invading pathogens and endogenous triggers. Assembly of inflammasomes is induced by activation of a receptor protein. Many inflammasome receptors require the adapter protein ASC [apoptosis-associated speck-like protein containing a caspase-recruitment domain (CARD)], which consists of two domains, the N-terminal pyrin domain (PYD) and the C-terminal CARD. Upon activation, ASC forms large oligomeric filaments, which facilitate procaspase-1 recruitment. Here, we characterize the structure and filament formation of mouse ASC in vitro at atomic resolution. Information from cryo-electron microscopy and solid-state NMR spectroscopy is combined in a single structure calculation to obtain the atomic-resolution structure of the ASC filament. Perturbations of NMR resonances upon filament formation monitor the specific binding interfaces of ASC-PYD association. Importantly, NMR experiments show the rigidity of the PYD forming the core of the filament as well as the high mobility of the CARD relative to this core. The findings are validated by structure-based mutagenesis experiments in cultured macrophages. The 3D structure of the mouse ASC-PYD filament is highly similar to the recently determined human ASC-PYD filament, suggesting evolutionary conservation of ASC-dependent inflammasome mechanisms.

  2. How many records should be used in ASCE/SEI-7 ground motion scaling procedure?

    Science.gov (United States)

    Reyes, Juan C.; Kalkan, Erol

    2012-01-01

    U.S. national building codes refer to the ASCE/SEI-7 provisions for selecting and scaling ground motions for use in nonlinear response history analysis of structures. Because the limiting values for the number of records in the ASCE/SEI-7 are based on engineering experience, this study examines the required number of records statistically, such that the scaled records provide accurate, efficient, and consistent estimates of “true” structural responses. Based on elastic–perfectly plastic and bilinear single-degree-of-freedom systems, the ASCE/SEI-7 scaling procedure is applied to 480 sets of ground motions; the number of records in these sets varies from three to ten. As compared to benchmark responses, it is demonstrated that the ASCE/SEI-7 scaling procedure is conservative if fewer than seven ground motions are employed. Utilizing seven or more randomly selected records provides more accurate estimate of the responses. Selecting records based on their spectral shape and design spectral acceleration increases the accuracy and efficiency of the procedure.

  5. Probability-Based Design Criteria of the ASCE 7 Tsunami Loads and Effects Provisions (Invited)

    Science.gov (United States)

    Chock, G.

    2013-12-01

    Mitigation of tsunami risk requires a combination of emergency preparedness for evacuation in addition to providing structural resilience of critical facilities, infrastructure, and key resources necessary for immediate response and economic and social recovery. Critical facilities would include emergency response, medical, tsunami refuges and shelters, ports and harbors, lifelines, transportation, telecommunications, power, financial institutions, and major industrial/commercial facilities. The Tsunami Loads and Effects Subcommittee of the ASCE/SEI 7 Standards Committee is developing a proposed new Chapter 6 - Tsunami Loads and Effects for the 2016 edition of the ASCE 7 Standard. ASCE 7 provides the minimum design loads and requirements for structures subject to building codes such as the International Building Code utilized in the USA. In this paper we will provide a review emphasizing the intent of these new code provisions and explain the design methodology. The ASCE 7 provisions for Tsunami Loads and Effects enables a set of analysis and design methodologies that are consistent with performance-based engineering based on probabilistic criteria. . The ASCE 7 Tsunami Loads and Effects chapter will be initially applicable only to the states of Alaska, Washington, Oregon, California, and Hawaii. Ground shaking effects and subsidence from a preceding local offshore Maximum Considered Earthquake will also be considered prior to tsunami arrival for Alaska and states in the Pacific Northwest regions governed by nearby offshore subduction earthquakes. For national tsunami design provisions to achieve a consistent reliability standard of structural performance for community resilience, a new generation of tsunami inundation hazard maps for design is required. The lesson of recent tsunami is that historical records alone do not provide a sufficient measure of the potential heights of future tsunamis. Engineering design must consider the occurrence of events greater than

    Background: Regarding strategies improving the efficacy of stem cell transplantation in adipose tissue engineering, cell tracking might be useful. Here we report the in vivo tracking of adipose tissue derived stem cells (ASC) by means of nanoparticle labeling and magnetic resonance imaging (MRI). Here we report the in vivo tracking of adipose tissue derived stromal cells (ASC) by means of nanoparticle labeling and magnetic resonance imaging (MRI). Materials and methods: Human ASC were amplified and labeled with two types of magnetic nanoparticles (MNP), BNF starch and nanomag®-D-spio. Adipose tissue constructs were fabricated by seeding collagen scaffolds with labeled and unlabeled ASCs. Constructs were implanted subcutaneously in the back of severe combined immunodeficient (SCID) mice (n =69, group 1: control with cells w/o label, group 2: BNF starch labeled cells, group 3: nanomag®-D-spio labeled cells). MRI scans were performed at 24 hours, four, twelve and 28 days and four months in a 7.1 T animal device. Explanted constructs were analyzed histomorphometrically. Results: MRI scans showed high contrast of the labeled cells in t2-tse-sequence compared to unlabeled controls. Loss of volume of the implants was observed over time due to partial loss for transplanted cells without significant difference (level of significance p<0.017). Compared to histomorphometry, there was found a positiv correlations in measurement of implant size with a significant at day four (correlation coefficient =0.643; p=0.024) and day twelve (correlation coefficient =0.687; p=0.010). Additional Prussian blue stain showed iron in all implants. Significant differences between the three groups (significance level p<0.017) were found after twelve days between control group and group 3 (p=0.008) and after 28 days between control group and group 2 and 3 (p=0.011). Conclusion: Both MNPs might be suitable for tracking of ASC in vivo and show long term stability over 4 months. - Highlights:

  11. Antidepressant-Like Effects of Central BDNF Administration in Mice of Antidepressant Sensitive Catalepsy (ASC) Strain.

    2012-08-31

    Although numerous data evidence the implication of brain-derived neurotrophic factor (BDNF) in the pathophysiology of depression, the potential for BDNF to correct genetically defined depressive-like states is poorly studied. This study was aimed to reveal antidepressant-like effects of BDNF (300 ng, 2×, i.c.v.) on behavior and mRNA expression of genes associated with depression-like state in the brain in mice of antidepressant sensitive catalepsy (ASC) strain characterized by high hereditary predisposition to catalepsy and depressive-like features. Behavioral tests were held on the 7th-16th days after the first (4th-13th after the second) BDNF injection. Results showed that BDNF normalized impaired sexual motivation in the ASC males, and this BDNF effect differed, with advantageous effects, from that of widely used antidepressants. The anticataleptic effect of two BDNF injections was enhanced compared with a single administration. A tendency to decrease the immobility duration in tail-suspension test was observed in BDNF-treated ASC mice. The effects on catalepsy and sexual motivation were specific since BDNF did not alter locomotor and exploratory activity or social interest in the ASC mice. Along with behavioral antidepressant-like effects on the ASC mice, BDNF increased hippocampal mRNA levels of Bdnf and Creb1 (cAMP response element-binding protein gene). BDNF also augmented mRNA levels of Arc gene encoding Arc (Activity-regulated cytoskeleton-associated) protein involved in BDNF-induced processes of neuronal and synaptic plasticity in hippocampus and prefrontal cortex. The data suggest that: [1] BDNF is effective in the treatment of some genetically defined behavioral disturbances; [2] BDNF influences sexually-motivated behavior; [3] Arc mRNA levels may serve as a molecular marker of BDNF physiological activity associated with its long-lasting behavioral effects; [4] ASC mouse strain can be used as a suitable model to study mechanisms of BDNF effects on

    Sexual dysfunctions are the typical symptoms accompanying depressive disorders. However antidepressants which improve general state of the patients have no effect on sexual disorders. Mice of ASC (Antidepressant Sensitive Catalepsy) line with high hereditary predisposition to catalepsy were proposed as a model of genetically associated depressive-like condition. The work was aimed at comparison of behavioral indices of sexual motivation and social interest of ASC mice with those of mice of parental inbred AKR and CBA strains, and at the study of the effects of chronic fluoxetine treatment in doses of 10 and 20 mg/kg on these parameters in ASC mice. ASC males demonstrated reduced sexual motivation which was not corrected by fluoxetine. ASC mice did not differ in the expression of social interest and aggression towards juvenile intruder from mice of parental strains. Fluoxetine failed to alter social behavior of ASC mice in social interaction test but its higher dose decreased percentage of aggressors. ASC mouse line seems to be a perspective model to study genetic mechanisms of sexual dysfunctions associated with depressive conditions.

    Full Text Available The contemporary world witnesses growing popularity of foreign languages learning and their role in the modern society. The article is devoted to the problem of mutual borrowings from English and Spanish languages. The aim of the article is to investigate new tendencies in the English words borrowings, their establishment in the Spanish language and the other way round. The Spanish language is one of the most widespread languages in the world and it is a native language for different nationalities. On the other hand, English has borrowed quite a lot of Spanish words as well. The mutual enrichment of the languages makes the process of language teaching specific and it is important in the modern process of globalization where languages are the main resource of international cooperation. The article contains both theoretical and practical materials dedicated to the investigation of this problem. This article may be useful for a wide range of readers, students, scientists, linguists in the study of modern Spanish and English languages.

  20. Intracellular invasion of Orientia tsutsugamushi activates inflammasome in asc-dependent manner.

    Directory of Open Access Journals (Sweden)

    Jung-Eun Koo

    Full Text Available Orientia tsutsugamushi, a causative agent of scrub typhus, is an obligate intracellular bacterium, which escapes from the endo/phagosome and replicates in the host cytoplasm. O. tsutsugamushi infection induces production of pro-inflammatory mediators including interleukin-1β (IL-1β, which is secreted mainly from macrophages upon cytosolic stimuli by activating cysteine protease caspase-1 within a complex called the inflammasome, and is a key player in initiating and maintaining the inflammatory response. However, the mechanism for IL-1β maturation upon O. tsutsugamushi infection has not been identified. In this study, we show that IL-1 receptor signaling is required for efficient host protection from O. tsutsugamushi infection. Live Orientia, but not heat- or UV-inactivated Orientia, activates the inflammasome through active bacterial uptake and endo/phagosomal maturation. Furthermore, Orientia-stimulated secretion of IL-1β and activation of caspase-1 are ASC- and caspase-1- dependent since IL-1β production was impaired in Asc- and caspase-1-deficient macrophages but not in Nlrp3-, Nlrc4- and Aim2-deficient macrophages. Therefore, live O. tsutsugamushi triggers ASC inflammasome activation leading to IL-1β production, which is a critical innate immune response for effective host defense.

    2018-01-01

    Full Text Available The article is aimed at researching the efficiency of the use of assembly technologies to solve the task of classifying borrowers – natural entities in relation to the level of credit risk. Features of information support of the process of solving the task of classifying borrowers – natural entities were analyzed. The necessity of application of model assemblies as one of contemporary directions of processing of big data has been substantiated. The author’s own variant of algorithm of creation of an assembly on the basis of specialization of separate models-experts has been provided. The proposed approach is implemented in two versions according to the types of models used as experts. In the first variant the assembly consists of logit-regressions, in the second variant – of neural networks. An analysis of the obtained results has proved that the described assembly structure gives an opportunity to increase the accuracy of assessment of the credit risks of borrowers, and it is expedient to use neural networks as separate models-experts.

    Adipose derived stem cells (ASCs) are an important cell source for tissue regeneration and have been demonstrated the potential of tenogenic differentiation in vitro. This study explored the feasibility of using ASCs for engineered tendon repair in vivo in a rabbit Achilles tendon model. Total 30 rabbits were involved in this study. A composite tendon scaffold composed of an inner part of polyglycolic acid (PGA) unwoven fibers and an outer part of a net knitted with PGA/PLA (polylactic acid) fibers was used to provide mechanical strength. Autologous ASCs were harvested from nuchal subcutaneous adipose tissues and in vitro expanded. The expanded ASCs were harvested and resuspended in culture medium and evenly seeded onto the scaffold in the experimental group, whereas cell-free scaffolds served as the control group. The constructs of both groups were cultured inside a bioreactor under dynamic stretch for 5 weeks. In each of 30 rabbits, a 2 cm defect was created on right side of Achilles tendon followed by the transplantation of a 3 cm cell-seeded scaffold in the experimental group of 15 rabbits, or by the transplantation of a 3 cm cell-free scaffold in the control group of 15 rabbits. Animals were sacrificed at 12, 21 and 45 weeks post-surgery for gross view, histology, and mechanical analysis. The results showed that short term in vitro culture enabled ASCs to produce matrix on the PGA fibers and the constructs showed tensile strength around 50 MPa in both groups (p > 0.05). With the increase of implantation time, cell-seeded constructs gradually form neo-tendon and became more mature at 45 weeks with histological structure similar to that of native tendon and with the presence of bipolar pattern and D-periodic structure of formed collagen fibrils. Additionally, both collagen fibril diameters and tensile strength increased continuously with significant difference among different time points (p tendon tissue with fibril structure observable only at 45 weeks

The ability to regenerate new bone tissues that faithfully replicate the anatomy would revolutionize treatment options. Advances in the field of bone tissue engineering over the past few decades offer promising new treatment alternatives using biocompatible scaffold materials and autologous cells. This approach combined with recent advances in three-dimensional (3D) printing technologies may soon allow the generation of large, bioartificial bone grafts with custom, patient-specific architecture. In this study, we use a custom-built 3D printer to develop anatomically shaped polycaprolactone (PCL) scaffolds with varying internal porosities. These scaffolds are assessed for their ability to support induction of human adipose-derived stem cells (hASCs) to form vasculature and bone, two essential components of functional bone tissue. The development of functional tissues is assessed in vitro and in vivo. Finally, we demonstrate the ability to print large mandibular and maxillary bone scaffolds that replicate fine details extracted from patient's computed tomography scans. The findings of this study illustrate the capabilities and potential of 3D printed scaffolds to be used for engineering autologous, anatomically shaped, vascularized bone grafts. © 2014 Wiley Periodicals, Inc.

  7. "Subnational Borrowing in Japan : from 'Implicit Guarantee' to Market Discipline and Fiscal Rule"

    OpenAIRE

    2008-01-01

    In many countries, local borrowing is an important source for long-term development projects such as roads, bridges, and waterworks. Local borrowing for such projects is justified on the ground that benefit of these projects often last decades and the cost of these projects should be borne by future tax payers. However, there are serious concerns with issuance of local bonds by decentralized local governments. Local governments in Japan would not default on their borrowing because of such "im...

  8. Lexical borrowing by Khoekhoegowab from Cape Dutch and Afrikaans

    Full Text Available The present article instantiates types of lexical borrowing from Afrikaans and Dutch in Namibian Khoekhoegowab (also known as “Nama”/“Damara”, but occasionally also refers to borrowings in the opposite direction. Where evidence allows, loans are traced back beyond Afrikaans to the era of Cape Dutch and contemporary interethnic contacts. Various categories ranging from adoptions to phonologically integrated loans, hybrids and calques are presented and, where possible, historical inferences are offered. The high degree of translational equivalence between Khoekhoe serial verbs and Afrikaans compound verbs leads to the consideration of some grammatical aspects including replication and relexification. Finally, reference is made to a parallel between Afrikaans and “Khoekhoe Afrikaans” syntax pointed out by den Besten (2013: Afrikaans circumlocutions like ek / sy wat Anna is (Khoekhoe: Anna.ta / Anna.s are literal equivalents of the underlying phrasal structures of Khoekhoe surface nouns #stem.pgn# in first, second or third person, as accounted for by the “desentential hypothesis” (Haacke 2006.

    The Jing people are a recognized ethnic group in Guangxi, southwest China, who are the immigrants from Vietnam during the 16th century. They speak Vietnamese but with lots of language borrowings from Cantonese, Zhuang, and Mandarin. However, it's unclear if there is large-scale gene flow from surrounding populations into Jing people during their language change due to the very limited genetic information of this population. We collected blood samples from 37 Jing and 3 Han Chinese individuals from Wanwei, Shanxin, and Wutou islands in Guangxi and genotyped about 600,000 genome-wide single nucleotide polymorphisms (SNPs). We used Principal Component Analysis (PCA), ADMIXTURE analysis, f statistics, qpWave and qpAdm to infer the population genetic structure and admixture. Our data revealed that the Jing people are genetically similar to the populations in southwest China and mainland Southeast Asia. But compared with Vietnamese, they show significant evidence of gene flow from surrounding East Asians. The admixture proportion is estimated to be around 35-42% in different Jing groups using southern Han Chinese as a proxy. The majority of the paternal lineages of Jing people are most likely from surrounding East Asians. We conclude that the formation and language change of present-day Jing people have involved genetic assimilation of surrounding East Asian populations. The language borrowing, in this case, is not only a cultural phenomenon but has involved demic diffusion. © 2018 Wiley Periodicals, Inc.

    Among polymeric nanoparticles designed for cancer therapy, PLGA nanoparticles have become one of the most popular polymeric devices for chemotherapeutic-based nanoformulations against several kinds of malignant diseases. Promising properties, including long-circulation time, enhanced tumor localization, interference with "multidrug" resistance effects, and environmental biodegradability, often result in an improvement of the drug bioavailability and effectiveness. In the present work, we have synthesized 1,7-bis(3,4-dimethoxyphenyl)-5-hydroxyhepta-1,4,6-trien-3-one (ASC-J9) and developed uniform ASC-J9-loaded PLGA nanoparticles of about 120 nm, which have been prepared by a single-emulsion process. Structural and morphological features of the nanoformulation were analyzed, followed by an accurate evaluation of the in vitro drug release kinetics, which exhibited Fickian law diffusion over 10 days. The intracellular degradation of ASC-J9-bearing nanoparticles within estrogen-dependent MCF-7 breast cancer cells was correlated to a time- and dose-dependent activity of the released drug. A cellular growth inhibition associated with a specific cell cycle G2/M blocking effect caused by ASC-J9 release inside the cytosol allowed us to put forward a hypothesis on the action mechanism of this nanosystem, which led to the final cell apoptosis. Our study was accomplished using Annexin V-based cell death analysis, MTT assessment of proliferation, radical scavenging activity, and intracellular ROS evaluation. Moreover, the intracellular localization of nanoformulated ASC-J9 was confirmed by a Raman optical imaging experiment designed ad hoc. PLGA nanoparticles and ASC-J9 proved also to be safe for a healthy embryo fibroblast cell line (3T3-L1), suggesting a possible clinical translation of this potential nanochemotherapeutic to expand the inherently poor bioavailability of hydrophobic ASC-J9 that could be proposed for the treatment of malignant breast cancer.

  11. Function of microRNAs in the Osteogenic Differentiation and Therapeutic Application of Adipose-Derived Stem Cells (ASCs

    Full Text Available Traumatic wounds with segmental bone defects represent substantial reconstructive challenges. Autologous bone grafting is considered the gold standard for surgical treatment in many cases, but donor site morbidity and associated post-operative complications remain a concern. Advances in regenerative techniques utilizing mesenchymal stem cell populations from bone and adipose tissue have opened the door to improving bone repair in the limbs, spine, and craniofacial skeleton. The widespread availability, ease of extraction, and lack of immunogenicity have made adipose-derived stem cells (ASCs particularly attractive as a stem cell source for regenerative strategies. Recently it has been shown that small, non-coding miRNAs are involved in the osteogenic differentiation of ASCs. Specifically, microRNAs such as miR-17, miR-23a, and miR-31 are expressed during the osteogenic differentiation of ASCs, and appear to play a role in inhibiting various steps in bone morphogenetic protein-2 (BMP2 mediated osteogenesis. Importantly, a number of microRNAs including miR-17 and miR-31 that act to attenuate the osteogenic differentiation of ASCs are themselves stimulated by transforming growth factor β-1 (TGFβ-1. In addition, transforming growth factor β-1 is also known to suppress the expression of microRNAs involved in myogenic differentiation. These data suggest that preconditioning strategies to reduce TGFβ-1 activity in ASCs may improve the therapeutic potential of ASCs for musculoskeletal application. Moreover, these findings support the isolation of ASCs from subcutaneous fat depots that tend to have low endogenous levels of TGFβ-1 expression.

  12. NLRP3 and ASC suppress lupus-like autoimmunity by driving the immunosuppressive effects of TGF-β receptor signalling.

    The NLRP3/ASC inflammasome drives host defence and autoinflammatory disorders by activating caspase-1 to trigger the secretion of mature interleukin (IL)-1β/IL-18, but its potential role in autoimmunity is speculative. We generated and phenotyped Nlrp3-deficient, Asc-deficient, Il-1r-deficient and Il-18-deficient C57BL/6-lpr/lpr mice, the latter being a mild model of spontaneous lupus-like autoimmunity. While lack of IL-1R or IL-18 did not affect the C57BL/6-lpr/lpr phenotype, lack of NLRP3 or ASC triggered massive lymphoproliferation, lung T cell infiltrates and severe proliferative lupus nephritis within 6 months, which were all absent in age-matched C57BL/6-lpr/lpr controls. Lack of NLRP3 or ASC increased dendritic cell and macrophage activation, the expression of numerous proinflammatory mediators, lymphocyte necrosis and the expansion of most T cell and B cell subsets. In contrast, plasma cells and autoantibody production were hardly affected. This unexpected immunosuppressive effect of NLRP3 and ASC may relate to their known role in SMAD2/3 phosphorylation during tumour growth factor (TGF)-β receptor signalling, for example, Nlrp3-deficiency and Asc-deficiency significantly suppressed the expression of numerous TGF-β target genes in C57BL/6-lpr/lpr mice and partially recapitulated the known autoimmune phenotype of Tgf-β1-deficient mice. These data identify a novel non-canonical immunoregulatory function of NLRP3 and ASC in autoimmunity. Published by the BMJ Publishing Group Limited.

  13. Optimizing the ASC WAN: evaluating network performance tools for comparing transport protocols.

    Energy Technology Data Exchange (ETDEWEB)

    Lydick, Christopher L.

    2007-07-01

    The Advanced Simulation & Computing Wide Area Network (ASC WAN), which is a high delay-bandwidth network connection between US Department of Energy National Laboratories, is constantly being examined and evaluated for efficiency. One of the current transport-layer protocols which is used, TCP, was developed for traffic demands which are different from that on the ASC WAN. The Stream Control Transport Protocol (SCTP), on the other hand, has shown characteristics which make it more appealing to networks such as these. Most important, before considering a replacement for TCP on any network, a testing tool that performs well against certain criteria needs to be found. In order to try to find such a tool, two popular networking tools (Netperf v.2.4.3 & v.2.4.6 (OpenSS7 STREAMS), and Iperf v.2.0.6) were tested. These tools implement both TCP and SCTP and were evaluated using four metrics: (1) How effectively can the tool reach a throughput near the bandwidth? (2) How much of the CPU does the tool utilize during operation? (3) Is the tool freely and widely available? And, (4) Is the tool actively developed? Following the analysis of those tools, this paper goes further into explaining some recommendations and ideas for future work.

    The purpose of this study was to evaluate the clinical significance of Human papillomavirus (HPV) DNA cotesting in Korean women with abnormal Papanicolaou (Pap) smear results based on colposcopic pathology. A total of 1012 women underwent liquid-based Pap smears and hybrid capture II HPV DNA tests followed by colposcopy at the Korea University Hospital from January 2007 to May 2012. Of these women, 832 women were included in this retrospective study. The mean patient age was 45.4 ± 13.7 years (range:15-80). The distribution of Pap smear results was normal (4.7%), atypical squamous cells of uncertain significance (ASCUS) (42.1%), low-grade squamous intraepithelial lesion (26.8%), ASC-H (7.0%), and high-grade squamous intraepithelial lesion (HSIL) (19.5%). In women with ASCUS, none of the 87 HPV-negative had ≥cervical intraepithelial neoplasia (CIN2) (P age groups: ASCUS and ASC-H furnish healthcare providers with informative data. There is a lower proportion of ≥CIN2 in HPV-negative women and a higher proportion of ≥CIN2 in HPV-positive. When HPV data were further evaluated by age group, the risk of ≥CIN2 was lower in HPV-negative women, especially in women ≥30. © 2014 Wiley Periodicals, Inc.

    The standardized form of the well-known FAO Penman-Monteith equation, published by the Environmental and Water Resources Institute of the American Society of Civil Engineers (ASCE-EWRI), is recommended as a standard procedure for calculating reference evapotranspiration (ET ref) and subsequently plant water requirements. Applied and validated under different climatic conditions it generally achieved good results compared to other methods. However, several studies documented deviations between measured and calculated reference evapotranspiration depending on environmental and weather conditions. Therefore, it seems generally advisable to evaluate the model under local environmental conditions. In this study, reference evapotranspiration was determined at a subhumid site in northeastern Austria from 2005 to 2010 using a large weighing lysimeter (ET lys). The measured data were compared with ET ref calculations. Daily values differed slightly during a year, at which ET ref was generally overestimated at small values, whereas it was rather underestimated when ET was large, which is supported also by other studies. In our case, advection of sensible heat proved to have an impact, but it could not explain the differences exclusively. Obviously, there were also other influences, such as seasonal varying surface resistance or albedo. Generally, the ASCE-EWRI equation for daily time steps performed best at average weather conditions. The outcomes should help to correctly interpret ET ref data in the region and in similar environments and improve knowledge on the dynamics of influencing factors causing deviations.

    As the knowledge about the interferences of nanomaterials on human staminal cells are scarce and contradictory, we undertook a comparative multidisciplinary study based on the size effect of zero-valent iron, cobalt, and nickel microparticles (MPs) and nanoparticles (NPs) using human adipose stem cells (hASCs) as a model, and evaluating cytotoxicity, morphology, cellular uptake, and gene expression. Our results suggested that the medium did not influence the cell sensitivity but, surprisingly, the iron microparticles (FeMPs) resulted in being toxic. These data were supported by modifications in mRNA expression of some genes implicated in the inflammatory response. Microscopic analysis confirmed that NPs, mainly internalized by endocytosis, persist in the vesicles without any apparent cell damage. Conversely, MPs are not internalized, and the effects on hASCs have to be ascribed to the release of ions in the culture medium, or to the reduced oxygen and nutrient exchange efficiency due to the presence of MP agglomerating around the cells. Notwithstanding the results depicting a heterogeneous scene that does not allow drawing a general conclusion, this work reiterates the importance of comparative investigations on MPs, NPs, and corresponding ions, and the need to continue the thorough verification of NP and MP innocuousness to ensure unaffected stem cell physiology and differentiation.

    2011-10-01

    Full Text Available Abstract: This article focuses on the lemmatisation of vowel-commencing borrowed nouns and the allo-cation of borrowed nouns to noun class prefixes in Isichazamazwi SesiNdebele, the first monolingual general-purpose Ndebele dictionary, and Isichazamazwi SezoMculo, the first specialised Ndebele dictionary of musical terms. It adopts a comparative approach, also highlighting the controversies surrounding the status of the initial vowel of the prefix or the pre-prefix in Ndebele and other Nguni languages. It further looks at the challenges and limitations of lemmatising the noun using either the initial vowel of the prefix or the initial letter of the noun stem. It is found that there are some inconsistencies in the lemmatisation of vowel-com-mencing borrowed nouns and the allocation of borrowed nouns to noun class prefixes in the two dictionar-ies. These inconsistencies impact negatively on the standardisation and treatment of borrowed nouns.

  18. Understanding Indonesian People Borrowing Money from Banks and Non-Banking Institutions

    2016-12-01

    Full Text Available People’s borrowing behaviours are influenced by the need to fulfil their basic needs which always change in maintaining their lifestyles. This thesis analyzes the tendency of Indonesians to borrowing money, either from banks or non-banking institutions. This research was carried out using quantitative data analysis with secondary data from the Indonesian Family Life Survey panel data versions 3 and 4. The data was analyzed using STATA 12.0 software. The results of the study show that the significant factors that affect people’s behaviour in borrowing from either banks or non-banking institutions are amount of debt, assets, income, and location; while the insignificant factors are age, religion, and number of householders.   Keywords: money borrowing, borrowing behaviour, debt, IFLS, STATA

    Full Text Available Background/Aim. Bethesda system of classification of cytological findings was introduced in 2001 two subcategories in the category of atypical squamous cells (ASC findings: ASC of undetermined significance (ASC-US and ASC which cannot exclude high-grade intraepithelial lesions (ASC-H. The aim of our study was to assess a possible association of these two subcategories with pathologic biopsy finding and to find out the best further diagnostic proceedings. Methods. At the Clinic of Gynecology and Obstetrics, Niš 130 patients with ASC findings were analyzed. Colposcopy was performed in all study participants. Patients with pathological colposcopic findings underwent cervical biopsy. In 10 patients with pathologic histologic and 15 with benign findings human papilloma virus (HPV typization was done using the Hybrid Capture method. Results. Patients with ASC-H finding had significantly more pathologic biopsies compared with patients with ASC-US finding (57.84: 20.72. Conclusion. Colposcopy was exhibited somewhat higher sensitivity compared to HPV typization (94.7 : 90, but lower sensitivity (79.27 : 86.6. The usage of HPV typization in the triage of patients with ASC cytologic smear induces statistically significant reduction of unnecessary percentage of cervical biopsies.

  20. Fish assemblages in borrow-pit lakes of the Lower Mississippi River

    Miranda, Leandro E.; Killgore, K. J.; Hoover, J.J.

    2013-01-01

    Borrow-pit lakes encompass about a third of the lentic water habitats (by area) in the active floodplain of the Lower Mississippi River, yet little is known about their fish assemblages. We investigated whether fish assemblages supported by borrow-pit lakes resembled those in oxbow lakes to help place the ecological relevance of borrow-pit lakes in context with that of natural floodplain lakes. In all, we collected 75 fish species, including 65 species in eight borrow-pit lakes, 52 species in four riverside oxbow lakes, and 44 species in eight landside oxbow lakes. Significant differences in several species richness metrics were evident between borrow-pit lakes and landside oxbow lakes but not between borrow-pit lakes and riverside oxbow lakes. All three lake types differed in fish assemblage composition. Borrow-pit lakes and riverside oxbow lakes tended to include a greater representation of fish species that require access to diverse environments, including lentic, lotic, and palustrine habitats; fish assemblages in landside oxbow lakes included a higher representation of lacustrine species. None of the fish species collected in borrow-pit lakes was federally listed as threatened or endangered, but several were listed as species of special concern by state governments in the region, suggesting that borrow-pit lakes provide habitat for sensitive riverine and wetland fish species. Differences in fish assemblages among borrow-pit lakes were linked to engineered morphologic features, suggesting that diversity in engineering can contribute to diversity in fish assemblages; however, more research is needed to match engineering designs with fish assemblage structures that best meet conservation needs.

  1. Atypical squamous cells, cannot exclude high grade squamous intraepithelial (ASC-H in HIV-positive women

    Full Text Available Objective: South Africa has very high rates of both HIV infection and cervical pathology. The management of ASC-H is colposcopy and directed biopsy, but with so many women diagnosed with HSIL and a dearth of colposcopy centres in South Africa, women with cytologic diagnosis of ASC-H may not be prioritized for colposcopy. The aim of this study was to determine if HIV-positive women with a cytologic diagnosis of ASC-H should undergo immediate colposcopy or whether colposcopy can be delayed, within the context of an underfunded health care setting with so many competing health needs. Materials and Methods: A computer database search was performed from the archives of an NGO-administered clinic that offers comprehensive HIV care. All women with a cytologic diagnosis of ASC-H on cervical smears from September 2005 until August 2009 were identified. Histologic follow up was sought in all patients. Results: A total of 2111 cervical smears were performed and 41 diagnosed as ASC-H (1.94%. No histologic follow up data was available in 15 cases. Follow up histologic results were as follows: three negative (11.5%, five koilocytosis and/ or CIN1 (19.2%, ten CIN2 (38.5% and eight CIN3 (30.8%. There were no cases of invasive carcinoma on follow up. Conclusion: The current appropriate management of HIV-positive women in low-resource settings with a diagnosis of ASC-H on cervical smear is colposcopy, despite the costs involved. In the future and if cost-effective in developing nations, use of novel markers may help select which HIV-positive women can be managed conservatively and which ones referred for more active treatment. More research in this regard is warranted.

    2015-01-01

    Various organic materials are used as essential parts in Stirling Convertors for their unique properties and functionalities such as bonding, potting, sealing, thread locking, insulation, and lubrication. More efficient Advanced Stirling Convertors (ASC) are being developed for future space applications especially with a long mission cycle, sometimes up to 17 years, such as deep space exploration or lunar surface power or Mars rovers, and others. Thus, performance, durability, and reliability of those organics should be critically evaluated in every possible material-process-fabrication-service environment relations based on their mission specifications. In general, thermal stability, radiation hardness, outgassing, and material compatibility of the selected organics have been systematically evaluated while their process and fabrication conditions and procedures were being optimized. Service environment-simulated long term aging tests up to 4 years were performed as a function of temperature for durability assessment of the most critical organic material systems.

  3. Sliding and Rocking of Unanchored Components and Structures: Chapter 7.6 ASCE 4 Revision 2

    2011-04-01

    Chapter 7.6 of ASCE 4-Rev 2, Seismic Analysis of Safety-Related Nuclear Structures: Standard and Commentary, provides updated guidance for analysis of rocking and sliding of unanchored structures and components subjected to seismic load. This guidance includes provisions both for simplified approximate energy-based approaches, and for detailed probabilistic time history analysis using nonlinear methods. Factors to be applied to the analytical results are also provided with the intent of ensuring achievement of the 80% non-exceedence probability target of the standard. The present paper surveys the published literature supporting these provisions. The results of available testing and analysis are compared to results produced by both simplified and probabilistic approaches. In addition, adequacy of the standard's provisions for analysis methods and factors is assessed. A comparison is made between the achieved level of conservatism and the standard's non-exceedence probability target.

    This report presents findings from a survey of U.S. dental school deans designed to capture their perceptions regarding the rising cost of dental education and its impact on borrowing by dental students to finance their education. The survey included questions about factors influencing the cost of dental education, concerns about dental student borrowing, and financial awareness resources for students. The survey was distributed to the deans of all 63 U.S. dental schools in January 2013; 42 deans responded, for a 67% response rate. The results indicate that, according to the responding deans, new clinical technologies, technology costs, and central university taxes are the main factors that contribute to the increasing cost of dental education. Coupled with reduced state appropriations at public dental schools and declines in private giving at all dental schools, dental school deans face a perplexing set of financial management challenges. Tuition and fees are a primary source of revenue for all dental schools; however, many deans do not have total control over the cost of attending their schools since tuition and fees are often tied to mandates and policies from the parent university and the state legislature. The findings of this study indicate that U.S. dental school deans are aware of and concerned about the impact of increases in tuition and fees on dental student debt and that they are using a variety of strategies to address the growth in dental student borrowing.

  8. Characterization of a novel variant of amino acid transport system asc in erythrocytes from Przewalski's horse (Equus przewalskii).

    Fincham, D A; Ellory, J C; Young, J D

    1992-08-01

    In thoroughbred horses, red blood cell amino acid transport activity is Na(+)-independent and controlled by three codominant genetic alleles (h, l, s), coding for high-affinity system asc1 (L-alanine apparent Km for influx at 37 degrees C congruent to 0.35 mM), low-affinity system asc2 (L-alanine Km congruent to 14 mM), and transport deficiency, respectively. The present study investigated amino acid transport mechanisms in red cells from four wild species: Przewalski's horse (Equus przewalskii), Hartmann's zebra (Zebra hartmannae), Grevy's zebra (Zebra grevyi), and onager (Equus hemonius). Red blood cell samples from different Przewalski's horses exhibited uniformly high rates of L-alanine uptake, mediated by a high-affinity asc1-type transport system. Mean apparent Km and Vmax values (+/- SE) for L-alanine influx at 37 degrees C in red cells from 10 individual animals were 0.373 +/- 0.068 mM and 2.27 +/- 0.11 mmol (L cells.h), respectively. As in thoroughbreds, the Przewalski's horse transporter interacted with dibasic as well as neutral amino acids. However, the Przewalski asc1 isoform transported L-lysine with a substantially (6.4-fold) higher apparent affinity than its thoroughbred counterpart (Km for influx 1.4 mM at 37 degrees C) and was also less prone to trans-stimulation effects. The novel high apparent affinity of the Przewalski's horse transporter for L-lysine provides additional key evidence of functional and possible structural similarities between asc and the classical Na(+)-dependent system ASC and between these systems and the Na(+)-independent dibasic amino acid transport system y+. Unlike Przewalski's horse, zebra red cells were polymorphic with respect to L-alanine transport activity, showing high-affinity or low-affinity saturable mechanisms of L-alanine uptake. Onager red cells transported this amino acid with intermediate affinity (apparent Km for influx 3.0 mM at 37 degrees C). Radiation inactivation analysis was used to estimate the target

    Since the Nuclear Material Control Center (NMCC) was designed the safeguards inspection organization by Ministry of Education, Culture, Sports, Science and Technology (MEXT) in December 1999, the NMCC has been performing safeguards inspection for the Nuclear Facilities in Japan. The NMCC has carried out the safeguards inspections to LEU Fuel Fabrication Plants (FFPs) and the NMCC has improved the method of safeguards inspection as it has changed over to the integrated safeguards from the year of 2005. Concerning the Borrowing inspection between LEU FFPs, which is the precondition to change over to the integrated safeguards, it is needed to estimate the entire inventory in the facility within the limited time. Therefore, the NMCC has developed the system called IWES (In-process inventory Walk-through Examination System) to examine the inventory in process smoothly, quickly and correctly at borrowing inspection, check the entire inventory quantity and evaluate them. This report describes how IWES aiming at effective/efficient confirmation of in-process inventory has been developed and how it is applied to the borrowing inspection activities. (author)

    Full Text Available An agreement from Norwalk was issued in September 2002 on the basis of negotiations of Financial Accounting Standards Board (FASB a International Accounting Standards Board (IASB for the elimination of restrictions in the form of two different systems of financial reporting. The aim is to ensure absolute compatibility of existing U.S. GAAP and IFRS and the coordination of work programs in the future. Document Memorandum of Understanding was issued in 2006 in the frame of ongoing process of convergence, in which the FASB and IASB confirm their intention to create high-quality and global financial reporting standards. In this document there are specified areas, which would lead to convergence of procedures.Borrowing costs have been one from the fields, which was the subject of convergence works. U.S. GAAP dictated capitalization of borrowing costs incurred in connection with the acquisition of qualifying assets, while the IAS/IFRS leaved the decision on accounting entities, how it recognize and record borrowing costs incurred in connection with the acquisition of the assets.In the beginning, the method of analysis and description is used to identify and describe the basic difference of both systems, which had existed before the initiation of convergence within the frame of “Borrowing Costs” project. The above mentioned primary analysis has served as the basis for the further comparative analysis and synthesis.The paper further presents comparative analysis of two basic methodical approaches towards the borrowing costs reporting incurred in relation to the acquisition of the qualifying assets, which was possible to apply until 31st Dec 2008 under IFRS system.The comparative analysis is based on empirical company data. The subjects are mainly the differences in the indicators, which are used for the evaluation of the company financial situation.

    Full Text Available In the last 10 years sport psychology expanded its applicability in a variety of fields which have helped to address some of the challenges related to high level performance and sport competition. When we talk about performance in its wider sense, sport psychology is able to help develop a better understanding on how strategies can be adopted in improving general human performance levels. This includes increasing the knowledge of key concepts such as motivation, self-confidence and resilience. Furthermore performance in its wider sense helps in the understanding of the impact of stress and arousal and how these can affect both positively and negatively performance levels including appreciating individual differences as well as dynamics between groups of individuals. In this paper performance rather than solely be related to the field of competitive or professional sport has been discussed in people with ASCs and aims to explore how by adopting a positive psychological model in the formulation of individual assessments and subsequent interventions have led to improvement in individual skills, participation, engagement and ultimately quality of life. Positive psychological principles, such as the role of wellbeing and wellness, the PERMA Model has increased our understanding of human potentials, performance and wellbeing. The aim of this paper is to present and reflect on the applicability and benefits of adopting sport psychology models, the PERMA model and positive psychological principles in special education and care settings with the presentation and discussion of their theoretical and some practical implementation in two case studies.

  2. Differential regulation of caspase-1 activation, pyroptosis, and autophagy via Ipaf and ASC in Shigella-infected macrophages.

    Directory of Open Access Journals (Sweden)

    Toshihiko Suzuki

    2007-08-01

    Full Text Available Shigella infection, the cause of bacillary dysentery, induces caspase-1 activation and cell death in macrophages, but the precise mechanisms of this activation remain poorly understood. We demonstrate here that caspase-1 activation and IL-1beta processing induced by Shigella are mediated through Ipaf, a cytosolic pattern-recognition receptor of the nucleotide-binding oligomerization domain (NOD-like receptor (NLR family, and the adaptor protein apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain (ASC. We also show that Ipaf was critical for pyroptosis, a specialized form of caspase-1-dependent cell death induced in macrophages by bacterial infection, whereas ASC was dispensable. Unlike that observed in Salmonella and Legionella, caspase-1 activation induced by Shigella infection was independent of flagellin. Notably, infection of macrophages with Shigella induced autophagy, which was dramatically increased by the absence of caspase-1 or Ipaf, but not ASC. Autophagy induced by Shigella required an intact bacterial type III secretion system but not VirG protein, a bacterial factor required for autophagy in epithelial-infected cells. Treatment of macrophages with 3-methyladenine, an inhibitor of autophagy, enhanced pyroptosis induced by Shigella infection, suggesting that autophagy protects infected macrophages from pyroptosis. Thus, Ipaf plays a critical role in caspase-1 activation induced by Shigella independently of flagellin. Furthermore, the absence of Ipaf or caspase-1, but not ASC, regulates pyroptosis and the induction of autophagy in Shigella-infected macrophages, providing a novel function for NLR proteins in bacterial-host interactions.

  3. Brazilian Credit Union Member Groups: Borrower-dominated, Saver-dominated or Neutral Behavior?

    2013-01-01

    Full Text Available Theoretical models concerning Credit Unions (CUs suggest that the type of CU domination determines the way it allocates the monetary value it generates. A borrower- (saver- dominated CU benefits borrower (saver members at the expenses of saver (borrower members, and a neutral CU equally benefits its member groups.This paper applies direct measure of monetary benefits to each member group (Patin & McNiel, 1991a to testfor the existence of dominated behavior in Brazilian CUs, and is the first to apply panel data regressions to identify the determinants of CUs behavior. We use a unique panel data with 40,664 observations taken from 533 CUs affiliated with the largest Brazilian cooperative network. Results indicate Brazilian CUs are dominated by borrowers, but behave close to neutrality. Panel regression estimates show that common or multiple bond type,size and overdue loans of a CU have no effect on its behavior, the greater the total amount of loans over social capital and adjusted equity over total assets are the more likely a CU is borrower dominated, and the greater the age and current operational expenses over total asset of a CU are the more likely a CU is saver dominated.

  4. ASCS online fault detection and isolation based on an improved MPCA

    2014-09-01

    Multi-way principal component analysis (MPCA) has received considerable attention and been widely used in process monitoring. A traditional MPCA algorithm unfolds multiple batches of historical data into a two-dimensional matrix and cut the matrix along the time axis to form subspaces. However, low efficiency of subspaces and difficult fault isolation are the common disadvantages for the principal component model. This paper presents a new subspace construction method based on kernel density estimation function that can effectively reduce the storage amount of the subspace information. The MPCA model and the knowledge base are built based on the new subspace. Then, fault detection and isolation with the squared prediction error (SPE) statistic and the Hotelling ( T 2) statistic are also realized in process monitoring. When a fault occurs, fault isolation based on the SPE statistic is achieved by residual contribution analysis of different variables. For fault isolation of subspace based on the T 2 statistic, the relationship between the statistic indicator and state variables is constructed, and the constraint conditions are presented to check the validity of fault isolation. Then, to improve the robustness of fault isolation to unexpected disturbances, the statistic method is adopted to set the relation between single subspace and multiple subspaces to increase the corrective rate of fault isolation. Finally fault detection and isolation based on the improved MPCA is used to monitor the automatic shift control system (ASCS) to prove the correctness and effectiveness of the algorithm. The research proposes a new subspace construction method to reduce the required storage capacity and to prove the robustness of the principal component model, and sets the relationship between the state variables and fault detection indicators for fault isolation.

    In US cervical screening, immediate colposcopy is recommended for women with HPV-positive ASC-US (equivocal) cytology. We evaluated whether partial typing by Onclarity™ (BD) might identify HPV-positive women with low enough CIN3+ risk to permit 1-year follow-up instead. The NCI-Kaiser Permanente Northern California Persistence and Progression cohort includes a subset of 13,890 women aged 21+ with HC2 (Qiagen)-positive ASC-US at enrollment; current median follow-up is 3.0years. Using stratified random sampling, we typed 2079 archived enrollment specimens including 329 women subsequently diagnosed with CIN3+, 563 with CIN2, and 1187 with ASC-US was 5.2%; this establishes the "benchmark" risk for colposcopic referral. Hierarchically, 3-year cumulative risks for each typing channel were 16.0% for HPV16, 7.4% for HPV18, 7.0% for HPV31, 7.1% for grouped HPV33/58, 4.3% for HPV52, 3.9% for HPV45, 2.7% for HPV51, 1.6% for HPV39/68/35, and 1.3% for HPV59/56/66. ASC-US linked to HPV16, HPV18, HPV31, or HPV33/58 warrants immediate colposcopy. Optimal management of women with HPV52 or HPV45 is uncertain. Risk of women with only HPV51, HPV39/68/35, or HPV59/56/66 might be low enough to recommend 1-year retesting permitting viral clearance. This strategy would defer colposcopy for 40% of women with HPV-positive ASC-US, half of whom would be cotest-negative at 1-year return. Approximately 10% of those with CIN3 diagnosable at enrollment would be delayed 1year instead. Cost-effectiveness analyses are needed. Published by Elsevier Inc.

  7. How culture matters in educational borrowing? Chinese teachers’ dilemmas in a global era

    2015-12-01

    Full Text Available Educational borrowing may cause numerous dilemmas that emerge from cross-cultural differences among teachers in the globalization. Through the case study on the flipped classroom introduced from the United States into Chinese middle schools, this article presents an examination of dilemmas that teachers encountered during educational borrowing in the global era. Based on the theoretical literature on cultural-historical activity theory, the study used interviews, field observations, and documents from six secondary schools in mainland China for one and a half years to understand comprehensively the dilemmas that teachers encountered when implementing the flipped classroom. The findings indicate that understandings of knowledge production, transmission, and the goal of education in mainland China differ from those in the west, which is the main reason for the teacher dilemmas. Because of the diversity in social culture, we suggest that teachers should be more culturally sensitive and improve compatibility in the process of educational borrowing.

  8. The Third Pillar of the Basel Accord: Evidence of borrower discipline in the Kyrgyz banking system

    2016-07-01

    Full Text Available We empirically study the asset side of market discipline in the banking system of the Kyrgyz Republic, examining whether borrowers are willing to pay higher interest rates to high-quality banks. Based on dynamic panel models and a dataset with bank information from 23 banks over the period 2010–2012, our findings suggest the presence of market discipline induced by borrowers. In other words, banks with higher capital ratios and liquidity charge higher interest rates on loans. This result has several implications for the banking policy in Kyrgyzstan, where we can recommend to policymakers a disclosure policy following the Third Pillar of Basel III, because not only can the bank's creditors use bank information to penalize the excessive bank risk, but borrowers can also use this information to discipline their banks.

The questions of interest are first, whether indexes of consumer confidence have any predictive power on their own for future household saving and borrowing rates, and second, whether they contain information about future household saving and borrowing rates aside from the information contained in other available indicators. In addition to aggregate confidence indicators, their components are used to provide more precise information. Overall, the multiple linear regression analysis (OLS technique) of Polish time-series data gives positive answers to both questions. This finding supports the recommendation of combining the strengths of objective indicators (such as economic fundamentals) and subjective indicators (such as consumer confidence) to improve household financial behavior forecasts.

  10. Borrowing and Dictionary Compilation: The Case of the Indigenous South African Languages

    ABSTRACT: Borrowing occurs when a language adds a word from another language to its own lexicon. Languages in neighbouring regions often borrow from each other. In South Africa, there are over nine indigenous languages, in addition to Afrikaans and English, all of which coexist. In their coexistence they borrow from one another. African language dictionaries reveal that these languages have borrowed a great deal from Afrikaans and English. However, one would expect these dictionaries to reflect some borrowing from other indigenous languages; on the contrary, they include very few such words. Although, one encounters many words from indigenous languages being used by other African languages in their spoken language and literary works, these are not included in dictionaries. This article seeks to highlight factors contributing to the failure to include words borrowed from other indigenous languages in African language dictionaries.

    OPSOMMING: Ontlening en woordeboeksamestelling: Die geval van inheemse Suid-Afrikaanse tale. Ontlening vind plaas wanneer 'n taal 'n woord uit 'n ander taal by sy eie leksikon voeg. Tale in aangrensende streke leen dikwels van mekaar. Daar is meer as nege inheemse tale in Suid-Afrika, bo en behalwe Afrikaans en Engels, wat saam bestaan. In hulle naasbestaan leen hulle van mekaar. Afrikataal-woordeboeke getuig daarvan dat hierdie tale heelwat uit Afrikaans en Engels geleen het. Daar sou egter verwag kon word dat hierdie woordeboeke sal getuig van ontlening uit ander inheemse tale; in teendeel, hulle sluit baie min van sulke woorde in. Alhoewel baie woorde van inheemse tale in ander Afrikatale gebruik word in die gesproke taal en letterkundige werke, is hierdie woorde nie in die woordeboeke opgeneem nie. Die doel van hierdie artikel is om die faktore uit te lig wat bydra tot die versuim om leenwoorde van ander inheemse tale in die Afrikataal-woordeboeke op te neem.

    Full Text Available CONTEXT AND OBJECTIVE: The latest update of the Bethesda System divided the category of atypical squamous cells of undetermined significance (ASCUS into ASC-US (undetermined significance and ASC-H (high-grade intraepithelial lesion cannot be ruled out. The aims here were to measure the prevalence of pre-invasive lesions (cervical intraepithelial neoplasia, CIN II/III and cervical cancer among patients referred to Instituto Fernandes Figueira (IFF with ASC-H cytology, and compare them with ASC-US cases. DESIGN AND SETTING: Cross-sectional study with retrospective data collection, at the IFF Cervical Pathology outpatient clinic. METHODS: ASCUS cases referred to IFF from November 1997 to September 2007 were reviewed according to the 2001 Bethesda System to reach cytological consensus. The resulting ASC-H and ASC-US cases, along with new cases, were analyzed relative to the outcome of interest. The histological diagnosis (or cytocolposcopic follow-up in cases without such diagnosis was taken as the gold standard. RESULTS: The prevalence of CIN II/III in cases with ASC-H cytology was 19.29% (95% confidence interval, CI, 9.05-29.55% and the risk of these lesions was greater among patients with ASC-H than with ASC-US cytology (prevalence ratio, PR, 10.42; 95% CI, 2.39-45.47; P = 0.0000764.

    ASC-J9 ® is a recently-developed androgen receptor (AR)-degradation enhancer that effectively suppresses castration resistant prostate cancer (PCa) cell proliferation and invasion. The optimal half maximum inhibitory concentrations (IC 50 ) of ASC-J9 ® at various PCa cell confluences (20%, 50%, and 100%) were assessed via both short-term MTT growth assays and long-term clonogenic proliferation assays. Our results indicate that the IC 50 values for ASC-J9 ® increased with increasing cell confluency. The IC 50 values were significantly decreased in PCa AR-positive cells compared to PCa AR-negative cells or in normal prostate cells. This suggests that ASC-J9 ® may function mainly via targeting the AR-positive PCa cells with limited unwanted side-effects to suppress the surrounding normal prostate cells. Mechanism dissection indicated that ASC-J9 ® might function via altering the apoptosis signals to suppress the PCa AR-negative PC-3 cells. Preclinical studies using multiple in vitro PCa cell lines and an in vivo mouse model with xenografted castration-resistant PCa CWR22Rv1 cells demonstrated that ASC-J9 ® has similar AR degradation effects when dissolved in FDA-approved solvents, including DMSO, PEG-400:Tween-80 (95:5), DMA:Labrasol:Tween-80 (10:45:45), and DMA:Labrasol:Tween-20 (10:45:45). Together, results from preclinical studies suggest a potential new therapy with AR-degradation enhancer ASC-J9 ® may potentially be ready to be used in human clinical trials in order to better suppress PCa at later castration resistant stages.

Burns School of Medicine, University of Hawaii at Mānoa, 3Tissue Genesis, Inc., Honolulu, HI, USA Background: Adipose tissue is an abundant and potent source of adult stem cells for transplant therapy. In this study, we present our findings on the potential application of adipose-derived stem cells (ASCs as well as induced cardiac-like progenitors (iCPs derived from ASCs for the treatment of myocardial infarction. Methods and results: Human bone marrow (BM-derived stem cells, ASCs, and iCPs generated from ASCs using three defined cardiac lineage transcription factors were assessed in an immune-compromised mouse myocardial infarction model. Analysis of iCP prior to transplant confirmed changes in gene and protein expression consistent with a cardiac phenotype. Endpoint analysis was performed 1 month posttransplant. Significantly increased endpoint fractional shortening, as well as reduction in the infarct area at risk, was observed in recipients of iCPs as compared to the other recipient cohorts. Both recipients of iCPs and ASCs presented higher myocardial capillary densities than either recipients of BM-derived stem cells or the control cohort. Furthermore, mice receiving iCPs had a significantly higher cardiac retention of transplanted cells than all other groups. Conclusion: Overall, iCPs generated from ASCs outperform BM-derived stem cells and ASCs in facilitating recovery from induced myocardial infarction in mice. Keywords: adipose stem cells, myocardial infarction, cellular reprogramming, cellular therapy, piggyBac, induced cardiac-like progenitors

  9. Using social impact borrowing to expand preschool through third grade programs in urban public schools.

    Science.gov (United States)

    Temple, Judy A; Reynolds, Arthur J

    Budget constraints and difficulty raising taxes limit school districts from expanding education programming even when research shows that additional expenditures would generate economic benefits that are greater than costs. Recently, coalitions of private investors, philanthropists, education practitioners, and government finance analysts have emerged to create opportunities to expand education services that promise high rates of social net benefits without raising taxes or reducing other expenditures. These collaborators have a strong interest in obtaining careful estimates of educational program effectiveness. We describe the use of social-impact borrowing to increase access to the Child-Parent Center preschool-through-third-grade intervention for at-risk students in the Chicago Public School District. The partners include the city, school district, investors, nonprofit organizations, and a university. The key to the feasibility of social-impact borrowing is the ability to document that early intervention can reduce the need for later special-education services. With the help of private investors and nonprofit organizations, it is possible for public school districts to finance services with funds from private sources and use future cost savings to repay this debt. We discuss how social-impact borrowing is being used in Chicago and in Salt Lake County as the nation's first two instances of using pay-for-performance social-impact borrowing to support early education.

    2016-09-01

    Full Text Available This article reports findings of a sociolinguistic project which investigated language contact phenomena in the speech of first-generation Hungarian Australians living in Sydney. The research aimed to identify and analyze English lexical items borrowed into the spoken Hungarian of first-generation Hungarian–English bilinguals. This research had a mixed methods approach including a quantitative element (count of lexical manifestations by categories such as part of speech and a qualitative element in which the various lexical manifestations have been subjected to a linguistic analysis. The Hungarian National Corpus was used as a reference guide to determine the status of these phenomena in the lexicon of Standard Hungarian. The data were collected through semi-structured sociolinguistic interviews with 22 Hungarian Australians living in Sydney. The findings demonstrate that (a first-generation Hungarians are highly creative language users and integrate a large number of English lexical items into their speech. Most lexical borrowings belong to the derivational blends with the highest proportion of the nominal group. Lexical borrowings from English are morphologically integrated with Hungarian-derivational suffixes and inflectional case markings. This research provides original empirical data to better understand the various inter-language lexical manifestations in Hungarian–English bilingual contexts. The study adds to the relatively small body of research on Hungarian–English bilingualism in diasporic context and contributes to understanding lexical borrowing from a contact linguistic perspective.

They embrace technology to give in-house debt collectors optimal opportunity to connect with customers to work out terms for resolving debt. They strategically leverage outside collections agencies based on the makeup of their debt portfolio.

    2016-02-01

    Full Text Available The aim of this study was to evaluate if low-frequency, low-magnitude vibrations (LFLM could enhance chondrogenic differentiation potential of human adipose derived mesenchymal stem cells (hASCs with simultaneous inhibition of their adipogenic properties for biomedical purposes. We developed a prototype device that induces low-magnitude (0.3 g low-frequency vibrations with the following frequencies: 25, 35 and 45 Hz. Afterwards, we used human adipose derived mesenchymal stem cell (hASCS, to investigate their cellular response to the mechanical signals. We have also evaluated hASCs morphological and proliferative activity changes in response to each frequency. Induction of chondrogenesis in hASCs, under the influence of a 35 Hz signal leads to most effective and stable cartilaginous tissue formation through highest secretion of Bone Morphogenetic Protein 2 (BMP-2, and Collagen type II, with low concentration of Collagen type I. These results correlated well with appropriate gene expression level. Simultaneously, we observed significant up-regulation of α3, α4, β1 and β3 integrins in chondroblast progenitor cells treated with 35 Hz vibrations, as well as Sox-9. Interestingly, we noticed that application of 35 Hz frequencies significantly inhibited adipogenesis of hASCs. The obtained results suggest that application of LFLM vibrations together with stem cell therapy might be a promising tool in cartilage regeneration.

Panel data model was used to observe the research. The sample of this study was 247 companies listed in Indonesia Stock Exchange for the years 2008-2010. The results show that modified audit opinion, except unqualified opinion with explanatory paragraph about going concern, did not affect borrowing cash flow because audit opinion was not the only consideration for granting credit by creditors. Companies receiving modified audit opinion were proven using more operating cash flow for investing shown in investment cash flow, especially companies receiving unqualified opinion with explanatory paragraph about going concern.

Moreover, the adverse economic effects of the bank tax were larger for smaller and more financially distressed firms, suggesting that bank levies are likely t...

    2016-06-01

    Full Text Available The article investigates the state of the credit portfolio of banks in the conditions of instability of the environment and the development of the credit rating of the borrower as a mechanism to prevent the direction of growth of bad debts. The research of the state and dynamics loan portfolio has revealed its sharp deterioration in recent years due to the instability of the external macro environment. The need to reduce the volume of bad debts requires the formation of an adequate mechanism for the borrower's credit rating. Under the mechanism defined in the article the subject-object interaction and providing subsystems have aimed at making management decisions about credit and credit determination capabilities of the enterprise. The authors propose the composition of such a mechanism from the position of a system approach with the subject-object allocation and providing subsystems. As a part of providing credit subsystems the article has allocated a methodological, methodical, information, personnel and organizational support. The article has formed the basic methodological principles of credit rating, namely a comprehensive assessment; the accuracy of the assessment; the progressiveness of the assessment; an objective assessment; professionalism; reality evaluation. Using the proposed credit assessment the mechanism in practice will enhance the effectiveness of the credit relationship between the bank and the borrower. Keywords: credit portfolio; mechanism; creditworthiness assessment; economic instability.

    Detailing the inflammatory mechanisms of biomaterial-implant induced foreign body responses (FBR) has implications for revealing targetable pathways that may reduce leukocyte activation and fibrotic encapsulation of the implant. We have adapted a model of poly(methylmethacrylate) (PMMA) bead injection to perform an assessment of the mechanistic role of the ASC-dependent inflammasome in this process. We first demonstrate that ASC−/− mice subjected to PMMA bead injections had reduced cell infiltration and altered collagen deposition, suggesting a role for the inflammasome in the FBR. We next investigated the NLRP3 and AIM2 sensors because of their known contributions in recognising damaged and apoptotic cells. We found that NLRP3 was dispensable for the fibrotic encapsulation; however AIM2 expression influenced leukocyte infiltration and controlled collagen deposition, suggesting a previously unexplored link between AIM2 and biomaterial-induced FBR.

    The use of magnetic nanoparticles (MNPs) towards the musculoskeletal tissues has been the focus of many studies, regarding MNPs ability to promote and direct cellular stimulation and orient tissue responses. This is thought to be mainly achieved by mechano-responsive pathways, which can induce changes in cell behavior, including the processes of proliferation and differentiation, in response to external mechanical stimuli. Thus, the application of MNP-based strategies in tissue engineering may hold potential to propose novel solutions for cell therapy on bone and cartilage strategies to accomplish tissue regeneration. The present work aims at studying the influence of MNPs on the osteogenic and chondrogenic differentiation of human adipose derived stem cells (hASCs). MNPs were incorporated in hASCs and cultured in medium supplemented for osteogenic and chondrogenic differentiation. Cultures were maintained up to 28 days with/without an external magnetic stimulus provided by a magnetic bioreactor, to determine if the MNPs alone could affect the osteogenic or chondrogenic phenotype of the hASCs. Results indicate that the incorporation of MNPs does not negatively affect the viability nor the proliferation of hASCs. Furthermore, Alizarin Red staining evidences an enhancement in extracellular (ECM) mineralization under the influence of an external magnetic field. Although not as evident as for osteogenic differentiation, Toluidine blue and Safranin-O stainings also suggest the presence of a cartilage-like ECM with glycosaminoglycans and proteoglycans under the magnetic stimulus provided. Thus, MNPs incorporated in hASCs under the influence of an external magnetic field have the potential to induce differentiation towards the osteogenic and chondrogenic lineages. - Highlights: • Cellular viability was not negatively influenced by the nanoparticles. • Chondrogenic medium influences more the synthesis of cartilage-like ECM than MNPs. • Synergetic effect among

    The ability to survive and proliferate in acidic environments is a prerequisite for the infection of Listeria monocytogenes. The glutamate decarboxylase (GAD) system is responsible for acid resistance, and three GAD homologs have been identified in L. monocytogenes: gadD1, gadD2, and gadD3. To examine whether GAD genes are specific to lineage, serovar, or certain subpopulation, we performed a systematic investigation on the prevalence of GAD genes in 164 L. monocytogenes. In contrast to gadD2 and gadD3 conserved in all L. monocytogenes strains, gadD1 was identified in 36.6% (60/164) of L. monocytogenes strains, including all serovar 1/2c and 68.5% (37/54) of serovar 1/2a strains, as well as a small fraction of serovar 1/2b (3.4%, 1/29) and lineage III (13.8%, 4/29) strains. All serovar 4b and lineage IV strains lacked this gene. According to the ascB-dapE structure, L. monocytogenes strains were classified into four subpopulations, carrying inlC2DE, inlGC2DE, inlGHE, or no internalin cluster, respectively. All L. monocytogenes strains with inlGC2DE or inlGHE pattern harbored gadD1, whereas those bearing inlC2DE or no internalin cluster between ascB and dapE lacked gadD1. In addition, other five non-monocytogenes Listeria species lacking ascB-dapE internalin cluster were gadD1-negative. Overall, the presence of gadD1 is not fully dependent on lineages or serovars but correlates with ascB-dapE internalin profiles, suggesting gadD1 might have co-evolved with the ascB-dapE internalin cluster in the primitive L. monocytogenes before divergence of serovars.

    Barrier islands provide protection to interior wetlands and maintain estuarine gradients. Mississippi River delta plain barrier islands are undergoing rapid disintegration due to high rates of subsidence and a deficit in the coastal sand supply. To mitigate for barrier island land loss, Louisiana has implemented a restoration program that intends to supplement coastal sand deficits by introducing sand from outside of the active coastal system. Inner-shelf shoals offshore Louisiana are one of the only sand resource options containing large volumes of restoration quality sand. Ship Shoal is one of these inner-shelf shoals that was produced by marine reworking of former Mississippi River Delta barrier island sediments during late Holocene time. Though indirect effects to protected areas or infrastructure adjacent to excavations have been considered, there is a paucity of observational data on their evolution. Caminada borrow area, dredged in 2013-2016 for the Caminada Headland Restoration Project, provides a valuable opportunity to validate and improve predictive models for how borrow areas evolve. In July 2017, a subbottom and bathymetric geophysical survey was conducted and sediment cores were collected to test the hypothesis that sedimentation within the excavation is affected by lateral bedload transport after initial rapid infill as slopes equilibrate. Preliminary results show the sediment within the excavation is predominantly very fine sand with isolated mud drapes. These sediments overlay older delta complex muddy strata. This contrasts strongly with other dredge pits outside of shoal areas and closer to shore, which have been infilled largely by advection of fine suspended sediments of fluvial origin. Laboratory work on cores will include laser grain size, x-ray analyses of sedimentary structures, and radiochemistry analyses for rates and age of deposition. With the knowledge of stratigraphy and sediment dynamics surrounding the dredge pit, we can quantify

    To understand the long-term economic implications of key pathways for financing a medical school education. The authors calculated the net present value (NPV) of cash flow over a 30-year career for a 2013 matriculant associated with (1) self-financing, (2) federally guaranteed loans, (3) the Public Service Loan Forgiveness program, (4) the National Health Service Corps, (5) the Armed Forces Health Professions Scholarship Program, and (6) matriculation at the Uniformed Services University of the Health Sciences. They calculated the NPV for students pursuing one of four specialties in two cities with divergent tax policies. Borrowers were assumed to have a median level of debt ($180,000), and conservative projections of inflation, discount rates, and income growth were employed. Sensitivity analyses examined different discount and income growth rates, alternative repayment strategies, and various lengths of public-sector service by scholarship recipients. For those wealthy enough to pay cash or fortunate enough to secure a no-strings scholarship, self-financing produced the highest NPV in almost every scenario. Borrowers start practice $300,000 to $400,000 behind their peers who secure a national service scholarship, but those who enter a highly paid specialty, such as orthopedic surgery, overtake their national service counterparts 4 to 11 years after residency. Those in lower-paid specialties take much longer. Borrowers who enter primary care never close the gap. Over time, the value of a medical degree offsets the high up-front cost. Debt avoidance confers substantial economic benefits, particularly for students interested in primary care.

    This article uses data from the Health and Retirement Study for 1998-2010 to investigate whether households respond to the financial stress caused by health problems by increasing their unsecured debt. Results show both the probability of having unsecured debt and the amount of debt increase after an adverse health event among households with low financial assets, who are uninsured, or who have less generous health insurance. The effect of health problems on borrowing is caused by both medical expenditures and disruptions to the income stream. Unsecured debt seems to remain on some households' balance sheets for an extended period. Copyright © 2012 John Wiley & Sons, Ltd.

  3. The deoxyhypusine synthase mutant dys1-1 reveals the association of eIF5A and Asc1 with cell wall integrity.

    Directory of Open Access Journals (Sweden)

    Fabio Carrilho Galvão

    Full Text Available The putative eukaryotic translation initiation factor 5A (eIF5A is a highly conserved protein among archaea and eukaryotes that has recently been implicated in the elongation step of translation. eIF5A undergoes an essential and conserved posttranslational modification at a specific lysine to generate the residue hypusine. The enzymes deoxyhypusine synthase (Dys1 and deoxyhypusine hydroxylase (Lia1 catalyze this two-step modification process. Although several Saccharomyces cerevisiae eIF5A mutants have importantly contributed to the study of eIF5A function, no conditional mutant of Dys1 has been described so far. In this study, we generated and characterized the dys1-1 mutant, which showed a strong depletion of mutated Dys1 protein, resulting in more than 2-fold decrease in hypusine levels relative to the wild type. The dys1-1 mutant demonstrated a defect in total protein synthesis, a defect in polysome profile indicative of a translation elongation defect and a reduced association of eIF5A with polysomes. The growth phenotype of dys1-1 mutant is severe, growing only in the presence of 1 M sorbitol, an osmotic stabilizer. Although this phenotype is characteristic of Pkc1 cell wall integrity mutants, the sorbitol requirement from dys1-1 is not associated with cell lysis. We observed that the dys1-1 genetically interacts with the sole yeast protein kinase C (Pkc1 and Asc1, a component of the 40S ribosomal subunit. The dys1-1 mutant was synthetically lethal in combination with asc1Δ and overexpression of TIF51A (eIF5A or DYS1 is toxic for an asc1Δ strain. Moreover, eIF5A is more associated with translating ribosomes in the absence of Asc1 in the cell. Finally, analysis of the sensitivity to cell wall-perturbing compounds revealed a more similar behavior of the dys1-1 and asc1Δ mutants in comparison with the pkc1Δ mutant. These data suggest a correlated role for eIF5A and Asc1 in coordinating the translational control of a subset of m

    2002-07-01

    The participants to the American Society of Civil Engineers (ASCE) prepared an application guide to provide guidelines to utilities and manufacturers on topics ranging from design to manufacture, testing and installation of fiber-reinforced polymer (FRP) products. The intent was also to help utilities with a possible replacement material for wood, steel and pre-stressed concrete. FRP products are constructed from fiber and resin and offer several advantages such as light weight and high strength-to-weight ratio, low maintenance, dimensional stability, resistance to rot, corrosion, chemicals and pest damage. FRP products can be used for lighting poles, ladders and grating, transformer pads, pole line hardware and crossarms, and other applications. There are five structural configurations: (1) cantilevered structures (single pole), (2) guyed structures, framed structures (H-Frame), (4) a combination of (1), (2), and (3), and (5) lattice structures (transmission class). The author listed some of the initial considerations: physical characteristics, guying and grounding, deflection and load testing, attached items, and durability to name only a few. The materials and manufacturing processes were briefly explained, namely the pultrusion method, the filament winding method, and the centrifugal casting method. Design loads considerations are discussed, as are performance-based criteria such as mechanical, coating durability and electrical. Quality control, assembly erection and storage, and in-service considerations are also discussed. The author concluded the presentation with a section dealing with field inspections. figs.

    Hypoxia is an important factor involved in the control of stem cells. To obtain a better insight into the phenotypical changes brought about by hypoxic preconditioning prior to chondrogenic differentiation; we have investigated growth, colony-forming and chondrogenic capacity, and global transcriptional responses of six adipose tissue-derived stem cell lines expanded at oxygen concentrations ranging from ambient to 1%. The assessment of cell proliferation and colony-forming potential revealed that the hypoxic conditions corresponding to 1% oxygen played a major role. The chondrogenic inducibility, examined by high-density pellet model, however, did not improve on hypoxic preconditioning. While the microarray analysis revealed a distinctive inter-donor variability, the exposure to 1% hypoxia superseded the biological variability and produced a specific expression profile with 2581 significantly regulated genes and substantial functional enrichment in the pathways of cell proliferation and apoptosis. Additionally, exposure to 1% oxygen resulted in upregulation of factors related to angiogenesis and cell growth. In particular, leptin (LEP), the key regulator of body weight and food intake was found to be highly upregulated. In conclusion, the results of this investigation demonstrate the significance of donor demographics and the importance of further studies into the use of regulated oxygen tension as a tool for preparation of ASCs in order to exploit their full potential.

    Sandy barrier islands along Louisiana coast are degrading rapidly due to both natural and anthropogenic factors. Ship Shoal is one of the largest offshore sand resources, and has been used as a borrow area for Caminada Headland Restoration Project. Our knowledge of sediment transport and infilling processes in this new sandy and dynamic borrow area is rather limited. High resolution sub-bottom seismic data, side scan sonar images, multi-beam bathymetry and laser sediment grain size data were used to study seafloor morphological evolution and pit wall stability in response to both physical and geological processes. The multi-beam bathymetry and seismic profiling inside the pit showed that disequilibrium conditions led to rapid infilling in the pits at the beginning, but this process slowed down after the pit slope became stable and topography became smooth. We hypothesize that the erosion of the adjacent seabed sediment by energetic waves and longshore currents, the supply of suspended sediment from the rivers, and the erodible materials produced by local mass wasting on pit walls are three main types of infilling sediments. Compared with mud-capped dredge pits, this sandy dredge pit seems to have more gentle slopes on pit walls, which might be controlled by the angle of repose. Infilling sediment seems to be dominantly sandy, with some mud patches on bathymetric depressions. This study helps us better understand the impacts of mining sediment for coastal restoration and improves sand resource management efforts.

  9. CAN THE MUSLIM WORLD BORROW FROM INDONESIAN CONSTITUTIONAL REFORM? A Comparative Constitutional Approach

    2007-06-01

    Full Text Available This paper attempts to analytically examine the possibility of constitutional borrowing for the Muslim world regardless the differences in history, system, culture, language, and cha­racteristics. It discusses this issue by looking at the arguments put forth by the oppo­nents of comparative cons­titutional interpre­tation and their counter arguments. It will consider materials from Canada, USA, South Africa, Singapore, Malaysia, and Hungary, taking the position that constitutional borrowing can be justified. The paper argues that the 1999-2002 Indonesian constitutional reform should be taken into account by other Muslim countries in undertaking their constitutional reform. The substantive approach of the Shari‘ah that has been used in Indonesia has shown that Muslim world can reform its constitutions without the “assistance” of Western foreign policy. Indo­nesian constitutional reform has demonstrated that Islamic constitutionalism comes from within Islamic teaching and the Islamic community itself; it is a home grown product.

    Listeria monocytogenes is an important foodborne pathogen encompassing four phylogenetic lineages. Lineages III and IV are rare, but have been reported to show considerable biodiversity, providing important clues for the evolutionary history in Listeria. In this study, analysis of the ascB-dapE locus reveals genetic diversity in lineages III and IV, and is consistent with the classification of sublineages. Four of the six genetic patterns (two of sublineage IIIC and two of lineage IV) are specific to these two lineages.

  13. Network protocol changes can improve DisCom WAN performance : evaluating TCP modifications and SCTP in the ASC tri-lab environment.

    Energy Technology Data Exchange (ETDEWEB)

    Tolendino, Lawrence F.; Hu, Tan Chang

    2005-06-01

    The Advanced Simulation and Computing (ASC) Distance Computing (DisCom) Wide Area Network (WAN) is a high performance, long distance network environment that is based on the ubiquitous TCP/IP protocol set. However, the Transmission Control Protocol (TCP) and the algorithms that govern its operation were defined almost two decades ago for a network environment vastly different from the DisCom WAN. In this paper we explore and evaluate possible modifications to TCP that purport to improve TCP performance in environments like the DisCom WAN. We also examine a much newer protocol, SCTP (Stream Control Transmission Protocol) that claims to provide reliable network transport while also implementing multi-streaming, multi-homing capabilities that are appealing in the DisCom high performance network environment. We provide performance comparisons and recommendations for continued development that will lead to network communications protocol implementations capable of supporting the coming ASC Petaflop computing environments.

  14. ASC-J9 Suppresses Castration-Resistant Prostate Cancer Growth through Degradation of Full-length and Splice Variant Androgen Receptors

    2012-01-01

    Full Text Available Early studies suggested androgen receptor (AR splice variants might contribute to the progression of prostate cancer (PCa into castration resistance. However, the therapeutic strategy to target these AR splice variants still remains unresolved. Through tissue survey of tumors from the same patients before and after castration resistance, we found that the expression of AR3, a major AR splice variant that lacks the AR ligand-binding domain, was substantially increased after castration resistance development. The currently used antiandrogen, Casodex, showed little growth suppression in CWR22Rv1 cells. Importantly, we found that AR degradation enhancer ASC-J9 could degrade both full-length (fAR and AR3 in CWR22Rv1 cells as well as in C4-2 and C81 cells with addition of AR3. The consequences of such degradation of both fAR and AR3 might then result in the inhibition of AR transcriptional activity and cell growth in vitro. More importantly, suppression of AR3 specifically by short-hairpin AR3 or degradation of AR3 by ASC-J9 resulted in suppression of AR transcriptional activity and cell growth in CWR22Rv1-fARKD (fAR knockdown cells in which DHT failed to induce, suggesting the importance of targeting AR3. Finally, we demonstrated the in vivo therapeutic effects of ASC-J9 by showing the inhibition of PCa growth using the xenografted model of CWR22Rv1 cells orthotopically implanted into castrated nude mice with undetectable serum testosterone. These results suggested that targeting both fAR- and AR3-mediated PCa growth by ASC-J9 may represent the novel therapeutic approach to suppress castration-resistant PCa. Successful clinical trials targeting both fAR and AR3 may help us to battle castration-resistant PCa in the future.

    This report provides in-depth information and analysis to help create a technical road map for developing next- generation Orogramming mocleN and runtime systemsl that support Advanced Simulation and Computing (ASC) work- load requirements. The focus herein is on 4synchronous many-task (AMT) model and runtime systems, which are of great interest in the context of "Oriascale7 computing, as they hold the promise to address key issues associated with future extreme-scale computer architectures. This report includes a thorough qualitative and quantitative examination of three best-of-class AIM] runtime systemsHCharm-HE, Legion, and Uintah, all of which are in use as part of the Centers. The studies focus on each of the runtimes' programmability, performance, and mutability. Through the experiments and analysis presented, several overarching Predictive Science Academic Alliance Program II (PSAAP-II) Ascl findings emerge. From a performance perspective, AIVT11runtimes show tremendous potential for addressing extreme- scale challenges. Empirical studies show an AM11 runtime can mitigate performance heterogeneity inherent to the machine itself and that Message Passing Interface (MP1) and AM11runtimes perform comparably under balanced con- ditions. From a programmability and mutability perspective however, none of the runtimes in this study are currently ready for use in developing production-ready Sandia ASCIapplications. The report concludes by recommending a co- design path forward, wherein application, programming model, and runtime system developers work together to define requirements and solutions. Such a requirements-driven co-design approach benefits the community as a whole, with widespread community engagement mitigating risk for both application developers developers. and high-performance computing inntime systein

    This report documents thirteen of Sandia's contributions to the Computational Systems and Software Environment (CSSE) within the Advanced Simulation and Computing (ASC) program between fiscal years 2009 and 2012. It describes their impact on ASC applications. Most contributions are implemented in lower software levels allowing for application improvement without source code changes. Improvements are identified in such areas as reduced run time, characterizing power usage, and Input/Output (I/O). Other experiments are more forward looking, demonstrating potential bottlenecks using mini-application versions of the legacy codes and simulating their network activity on Exascale-class hardware. The purpose of this report is to prove that the team has completed milestone 4467-Demonstration of a Legacy Application's Path to Exascale. Cielo is expected to be the last capability system on which existing ASC codes can run without significant modifications. This assertion will be tested to determine where the breaking point is for an existing highly scalable application. The goal is to stretch the performance boundaries of the application by applying recent CSSE RD in areas such as resilience, power, I/O, visualization services, SMARTMAP, lightweight LWKs, virtualization, simulation, and feedback loops. Dedicated system time reservations and/or CCC allocations will be used to quantify the impact of system-level changes to extend the life and performance of the ASC code base. Finally, a simulation of anticipated exascale-class hardware will be performed using SST to supplement the calculations. Determine where the breaking point is for an existing highly scalable application: Chapter 15 presented the CSSE work that sought to identify the breaking point in two ASC legacy applications-Charon and CTH. Their mini-app versions were also employed to complete the task. There is no single breaking point as more than one issue was found with the two codes. The results were

  18. Borrowed knowledge chaos theory and the challenge of learning across disciplines

    Kellert, Stephen H

    2009-01-01

    What happens to scientific knowledge when researchers outside the natural sciences bring elements of the latest trend across disciplinary boundaries for their own purposes? Researchers in fields from anthropology to family therapy and traffic planning employ the concepts, methods, and results of chaos theory to harness the disciplinary prestige of the natural sciences, to motivate methodological change or conceptual reorganization within their home discipline, and to justify public policies and aesthetic judgments.Using the recent explosion in the use (and abuse) of chaos theory, Borrowed Knowledge and the Challenge of Learning across Disciplines examines the relationship between science and other disciplines as well as the place of scientific knowledge within our broader culture. Stephen H. Kellert's detailed investigation of the myriad uses of chaos theory reveals serious problems that can arise in the interchange between science and other knowledge-making pursuits, as well as opportunities for constructive...

  19. Reflections on Asia: Borrowing Lessons from the Humanities in Social Science Coursework

    Howard Sanborn

    2017-07-01

    Full Text Available What lessons can political science classes borrow from the humanities? This paper presents the results of a multi-year study on teaching about Asia as part of a general education program. Given the challenges of meeting common learning outcomes while also teaching discipline-specific lessons, political science courses often underperformed in assessments when compared to benchmark expectations. While our initial conclusion—that a greater focus on multimodal assignments would promote deeper learning and reflection—proved unfounded, explicitly emphasizing students’ reflection on their own process of democratic engagement, in comparison to that of their counterparts in Asia, did seem to address the shortcomings of the previous approaches by giving students context and guidance in their understanding of how democracy works at home and abroad. Data from reflective essays, collected over two years, provide evidence for this finding.

  20. A revision of the subtract-with-borrow random number generators

    Science.gov (United States)

    Sibidanov, Alexei

    2017-12-01

    The most popular and widely used subtract-with-borrow generator, also known as RANLUX, is reimplemented as a linear congruential generator using large integer arithmetic with the modulus size of 576 bits. Modern computers, as well as the specific structure of the modulus inferred from RANLUX, allow for the development of a fast modular multiplication - the core of the procedure. This was previously believed to be slow and have too high cost in terms of computing resources. Our tests show a significant gain in generation speed which is comparable with other fast, high quality random number generators. An additional feature is the fast skipping of generator states leading to a seeding scheme which guarantees the uniqueness of random number sequences.

  1. A Public Choice Approach to the Unequal Treatment of Securities Market Participants and Home Borrowers

    Directory of Open Access Journals (Sweden)

    Jonathan Macey

    2017-01-01

    Full Text Available This article contrasts the protections provided to participants in U.S. securities markets with the protections provided to participants in the U.S. mortgage markets. Participants in securities markets purchase and sell equity and debt securities. Participants in the mortgage markets borrow money to buy homes, using those homes as collateral for the mortgage loans they receive. Even after Dodd-Frank, participants in securities markets are afforded significantly higher levels of protection than participants in mortgage markets. The doctrine of suitability is a prime example of this inequity. Exploring possible explanations for this odd asymmetry of treatment, I conclude that interest group politics is to blame for the anomaly.

    α-Chiral amines are key intermediates for the synthesis of a plethora of chemical compounds at industrial scale. We present a biocatalytic hydrogen-borrowing amination of primary and secondary alcohols that allows for the efficient and environmentally benign production of enantiopure amines. The method relies on a combination of two enzymes: an alcohol dehydrogenase (from Aromatoleum sp., Lactobacillus sp., or Bacillus sp.) operating in tandem with an amine dehydrogenase (engineered from Bacillus sp.) to aminate a structurally diverse range of aromatic and aliphatic alcohols, yielding up to 96% conversion and 99% enantiomeric excess. Primary alcohols were aminated with high conversion (up to 99%). This redox self-sufficient cascade possesses high atom efficiency, sourcing nitrogen from ammonium and generating water as the sole by-product.

    The 218-E-8 Demolition Site was the site of a single demolition event in November of 1984. This demolition event was a form of thermal treatment for discarded explosive chemical products. Because the 218-E-8 Demolition Site will no longer be used for this thermal activity, the site will be closed. Closure will be conducted pursuant to the requirements of the Washington State Department of Ecology (Ecology) ''Dangerous Waste Regulations,'' Washington Administrative Code (WAC) 173-303-610 and 40 Code of Federal Regulations (CFR) 270.1. The 218-E-8 Borrow Pit Demolition Site Closure Plan consists of a Hanford Facility Dangerous Waste Part A Permit Application, Form 3, Revision 4, and a closure plan. An explanation of the Part A Form 3, submitted with this closure plan is provided at the beginning of the Part A Section. The closure plan consists of nine chapters and five appendices. This closure plan presents a description of the 218-E-8 Demolition Site, the history of the waste treated, and the approach that will be followed to close the 218-E-8 Demolition Site. Because there were no radioactively contaminated chemicals involved in t he demolitions at the 218-E-8 Borrow Pit site, the information on radionuclides is provided for ''information only.'' Remediation of any radioactive contamination is not within the scope of this closure plan. Only dangerous constituents derived from 218-E-8 Demolition Site operations will be addressed in this closure plan in accordance with WAC 173-303-610(2)(b)(i)

    Unified collision operator demonstrated for both radiation transport and PIC-DSMC. A side-by-side comparison between the DSMC method and the radiation transport method was conducted for photon attenuation in the atmosphere over 2 kilometers in physical distance with a reduction of photon density of six orders of magnitude. Both DSMC and traditional radiation transport agreed with theory to two digits. This indicates that PIC-DSMC operators can be unified with the radiation transport collision operators into a single code base and that physics kernels can remain unique to the actual collision pairs. This simulation example provides an initial validation of the unified collision theory approach that will later be implemented into EMPIRE.

  15. Problems and prospects of modern methods of business analysis in the process of assessment of solvency of borrowers

    Directory of Open Access Journals (Sweden)

    Aptekar Saveliy S.

    2013-03-01

    Full Text Available The goal of the article is a comparative analysis of modern methods of business analysis in the process of assessment of solvency of borrowers of Ukrainian commercial banks, study of prospects and problems of the use of methods in the credit process. In the result of the study the article systemises and considers the conduct of the credit process of Ukrainian commercial banks. It becomes clear from result of the study that it is impossible to obtain a single assessment of solvency of a borrower with generalisation of numerical and non-numerical data. Assessment of qualified analysts is required for a justified assessment of solvency apart from information represented in numbers. Improvement of approaches to assessment of solvency of borrowers and adaptation of the existing foreign experience in this field to specific features of formation of solvency of Ukrainian borrowers are important tasks for the Ukrainian banking system. Prospects of further studies in this direction are establishment of importance of the conduct of business analysis and its key role in assessment of solvency of borrowers as a main instrument of minimisation of the credit risk. Improvement of this sphere of analytical work in Ukrainian banks should be carried out in the following main directions: study and analysis of qualitative indicators of business activity; analysis of main sections of the business plan; expansion of the composition of indicators of the financial analysis for obtaining information; conduct of analysis of possible sources of repayment of loan liabilities; and active use of analysis of cash flows of an enterprise.

    Full Text Available OBJETIVO: O objetivo do estudo foi verificar os efeitos da oferta de vitamina C através de um suplemento alimentar e dieta rica em ácido ascórbico (AA no estresse oxidativo induzido pelo exercício. MÉTODOS: A amostra foi composta por 13 nadadores de elite (seis homens e sete mulheres com idades entre 18 e 26 anos. Os mesmos atletas foram submetidos a sessão de exercício agudo em três fases, com diferentes tratamentos: controle (C, dieta rica em AA (D e suplemento de AA (S, nas quais amostras de sangue foram colhidas antes, imediatamente após e 24 horas depois do exercício. Para comparação entre as fases e etapas foi utilizado o modelo de regressão linear com efeitos mistos. RESULTADOS: O consumo alimentar habitual de antioxidantes não foi diferente entre as fases, apenas a ingestão de AA foi maior na fase D e S em relação à fase C. O uso de dieta rica em AA favoreceu uma menor peroxidação lipídica, devido aos menores valores de hidroperóxidos lipídicos (FOX, diminuição da peroxidação após exercício, pela diminuição de substâncias reativas ao ácido tiobarbitúrico (TBARS e aumento dos níveis de vitamina C logo após o exercício. O uso de suplemento de AA também conteve a peroxidação lipídica após exercício e aumentou o poder antioxidante, devido aos maiores níveis de glutationa reduzida (GSH. Sem adição de AA os nadadores tiveram um maior dano hepático, pois apresentaram maiores níveis de transaminase-glutâmico-oxalacética (TGO, menores níveis de antioxidantes (vitamina C e GSH e aumento do ácido úrico. CONCLUSÃO: Assim, as mudanças observadas com a adição de AA à dieta de nadadores sugerem um importante papel deste micronutriente na defesa contra o estresse oxidativo induzido pelo exercício.

    Full Text Available Abstract Background Cervical smears exhibiting unequivocal features of 'low grade squamous intraepithelial lesion' (LSIL are occasionally also admixed with some cells suspicious for, but not diagnostic of, 'high grade squamous intraepithelial lesion' (HSIL. Only a few studies, mostly reported as abstracts, have evaluated this concurrence. In this study, we evaluate the current evidence that favors a distinct category for "LSIL, cannot exclude HSIL" (LSIL-H, and suggest a management algorithm based on combinations of current ASCCP guidelines for related interpretations. Methods We studied SurePath™ preparations of cervical specimens from various institutions during one year period.

    The ratio of males to females in a population is an important factor in determining behavior in animals. We propose that sex ratio also has pervasive effects in humans, such as by influencing economic decisions. Using both historical data and experiments, we examined how sex ratio influences saving, borrowing, and spending in the United States. Findings show that male-biased sex ratios (an abundance of men) lead men to discount the future and desire immediate rewards. Male-biased sex ratios decreased men's desire to save for the future and increased their willingness to incur debt for immediate expenditures. Sex ratio appears to influence behavior by increasing the intensity of same-sex competition for mates. Accordingly, a scarcity of women led people to expect men to spend more money during courtship, such as by paying more for engagement rings. These findings demonstrate experimentally that sex ratio influences human decision making in ways consistent with evolutionary biological theory. Implications for sex ratio effects across cultures are discussed.

  20. Fiscal determinants of government borrowing costs: do we have only ourselves to blame?

    Directory of Open Access Journals (Sweden)

    Josip Funda

    2013-06-01

    Full Text Available The global financial crisis and the problems in peripheral EU countries resulted in increased attention to fiscal developments and their impact on borrowing costs for both public and private sector. Existing theoretical literature suggests that worsening of current and expected budget balances as well as an increase of public debt lead to a rise in short and long term interest rates for sovereign debtors. However, empirical results are inconclusive, especially for emerging market countries. This paper analyzes the factors that determine the dynamics of government bond spreads, with special emphasis on fiscal indicators. The survey covered 17 European countries, of which 9 are developed and 8 are emerging market economies, all of them members of the EU except Croatia. The empirical part of the paper employs dynamic panel data method and uses the Arellano and Bond estimator to get consistent estimates of parameters of interest. The results show that in the period 2004-2011 fiscal balance and public debt projections had a significant impact on the differences in government bond yields for emerging market countries, with the effect being much stronger during the period after the onset of financial crises. On the other hand, it seems that sovereign spread dynamics in developed countries is driven mostly by the global market sentiment.

    Multinational companies in Romania have imposed the use of the predominant language, in most cases - English, in professional communication. In contexts related to workplace communication, the main motivation for foreign borrowings is the need to denote concepts and activities. The article focuses on the English language as a wide source for a great number of innovations both at the lexical and the morphological level in the Romanian vocabulary related to business and technology. The aim of the paper is to demonstrate that Romanian language displays a natural disposition towards adopting and adapting foreign words, especially borrowed English terms, in the field of computer science and business without endangering its identity.

    Listeria monocytogenes is an important foodborne pathogen that comprises four genetic lineages: I, II, III, and IV. Of these, lineage II is frequently recovered from foods and environments and responsible for the increasing incidence of human listeriosis. In this study, the phylogenetic structure of lineage II was determined through sequencing analysis of the ascB-dapE internalin cluster. Fifteen sequence types proposed by multilocus sequence typing based on nine housekeeping genes were grouped into three distinct sublineages, IIA, IIB, and IIC. Organization of the ascBdapE internalin cluster could serve as a molecular marker for these sublineages, with inlGHE, inlGC2DE, and inlC2DE for IIA, IIB, and IIC, respectively. These sublineages displayed specific genetic and phenotypic characteristics. IIA and IIC showed a higher frequency of recombination (rho/theta). However, recombination events had greater effect (r/m) on IIB, leading to its high nucleotide diversity. Moreover, IIA and IIB harbored a wider range of internalin and stress-response genes, and possessed higher nisin tolerance, whereas IIC contained the largest portion of low-virulent strains owing to premature stop codons in inlA. The results of this study indicate that IIA, IIB, and IIC might occupy different ecological niches, and IIB might have a better adaptation to a broad range of environmental niches.

    To explore the HPVgenotype profile in Norwegian women with ASC-US/LSIL cytology and the subsequent risk of high-grade cervical neoplasia (CIN 3+). In this observational study delayed triage of ASC-US/LSIL of 6058 women were included from 2005 to 2010. High-risk HPV detection with Hybrid Capture 2 (HC2) was used and the HC2+ cases were genotyped with in-house nmPCR. Women were followed-up for histologically confirmed CIN3+ within three years of index HPV test by linkage to the screening databases at the Cancer Registry of Norway. HC2 was positive in 45% (2756/6058) of the women. Within 3years CIN3+ was diagnosed in 26% of womenrisk for CIN3+. Among older women, all 13 high-risk genotypes as single infection were associated with >20% risk of CIN3+. Further studies are necessary to risk stratify the individual genotypes to reduce the number of colposcopies in Norway. Copyright © 2017 Elsevier Inc. All rights reserved.

  4. Modification of Displacement Coefficient Method in Estimation of Target Displacement for Regular Concrete Bridges Based on ASCE 41-06 Standard

    Full Text Available Displacement Coefficient Method (DCM stipulated in the ASCE 41-06 standard is becoming the preferred method for seismic rehabilitation of buildings in many high-seismic-hazard countries. Applications of the method for non-building constructions such as bridges are beyond the scope of this standard. Thus its application to this kind of structure should be approached with care. Target displacement has reasonable accuracy for buildings with strong columns and weak beams, where there is the development of plastic hinges. Due to high stiffness and strength of the deck relative to the piers in most bridges, this mechanism does not occur, and it is necessary to evaluate the accuracy of DCM for such structures. In this research, an attempt is made to evaluate the credibility of DCM in the ASCE/SEI 41-06 standard for estimating target drifts in concrete regular bridges under strong ground motions. To apply the extension of the method to bridge structures, the definition of new correction factor CB, which should be multiplied to previous coefficients, is required. This novel coefficient can improve the accuracy of the mentioned method in accessing seismic displacement demands. The coefficient is presented for soil types A to D based on NEHRP soil classification. The validity of the modified DCM is examined for several bridges with use of nonlinear dynamic analysis. Good correlation is found between both procedures.

    1997-03-01

    The Department of Energy (DOE) prepared this Environmental Assessment (EA) to assess the potential environmental impacts of the proposed expansion and operation of an existing borrow pit at the Savannah River Site (SRS), located near Aiken, South Carolina. A borrow pit is defined as an excavated area where material has been dug for use as fill at another location. The proposed action would entail the areal enlargement, continued operation, and eventual close-out of the established facility known as the Central Shops Borrow Pit. Operations at SRS supporting waste site closure and the construction and maintenance of site facilities and infrastructure require readily available suitable soil for use as fill material. With the recent depletion of the other existing on-site sources for such material, DOE proposes to expand the existing facility. The National Environmental Policy Act requires the assessment of environmental consequences of Federal actions that may affect the quality of the human environment. Based on the potential for impacts described herein, DOE will either publish a Finding of No Significant Impact or prepare an Environmental Impact Statement (EIS)

    Full Text Available Nowadays advertising is of significant importance. Radio and television programmes, newspapers and magazines, various texts, even streets and shops are hardly imaginable without advertising. Advertising forms individuals’ as well as public attitude to many things in life. Besides it influences the person’s behavior and way of thinking. Advertising is inseparable part of the market; it helps create new working places, increases income and discloses positive qualities of manufactured products.However to create the correct, attractive and emotional body of the advert is not easy at all. Every person involved in advertising should be aware of that. In advertising texts vocabulary rules change, loanwords pushed, their standardisation and codification are noticed. In the period of integrating into the European Union, more new technological terms are used in the Lithuanian language. The language is being operated in virtual environment. New varieties of the language are being discovered - advertisement language and -communicative language. The problems of the usage of borrowed words also appear in the language.

    ABSTRACT: The influence of foreign languages in Sesotho sa Leboa, or Northern Sotho, results in borrowing, which ultimately leads to an increase in the vocabulary of Sesotho sa Leboa. The languages influencing developments in the vocabulary of Sesotho sa Leboa include, inter alia, English, Afrikaans, Xitsonga, Tshivend√a and the Nguni languages. This article aims to give a critical analysis of the advantages and disadvantages of the adoption of foreign lexical items in the lemmatization of vocabulary in Sesotho sa Leboa dictionaries. Most puristic inclined academics and intellectuals are reluctant to adopt loan words as a means of developing the Sesotho sa Leboa vocabulary. When confronted with borrowing, the purists usually prefer coinage, using indigenous lexical items to name foreign concepts. This is disadvantageous to the development of the vocabulary of the language because (1 there is no increase in the number of the lexical items in the language since only the meanings of the foreign lexical item are added to existing indigenous lexical items, and (2 in most cases, previously adopted loan words are mistaken for indigenous lexical items and given preference to newly acquired lexical items which have direct and accurate bearing on the meaning of the newly discovered or designed concepts or objects.

    Network meta-analysis (NMA) enables simultaneous comparison of multiple treatments while preserving randomisation. When summarising evidence to inform an economic evaluation, it is important that the analysis accurately reflects the dependency structure within the data, as correlations between outcomes may have implication for estimating the net benefit associated with treatment. A multivariate NMA offers a framework for evaluating multiple treatments across multiple outcome measures while accounting for the correlation structure between outcomes. The standard NMA model is extended to multiple outcome settings in two stages. In the first stage, information is borrowed across outcomes as well across studies through modelling the within-study and between-study correlation structure. In the second stage, we make use of the additional assumption that intervention effects are exchangeable between outcomes to predict effect estimates for all outcomes, including effect estimates on outcomes where evidence is either sparse or the treatment had not been considered by any one of the studies included in the analysis. We apply the methods to binary outcome data from a systematic review evaluating the effectiveness of nine home safety interventions on uptake of three poisoning prevention practices (safe storage of medicines, safe storage of other household products, and possession of poison centre control telephone number) in households with children. Analyses are conducted in WinBUGS using Markov Chain Monte Carlo (MCMC) simulations. Univariate and the first stage multivariate models produced broadly similar point estimates of intervention effects but the uncertainty around the multivariate estimates varied depending on the prior distribution specified for the between-study covariance structure. The second stage multivariate analyses produced more precise effect estimates while enabling intervention effects to be predicted for all outcomes, including intervention effects on

  19. Fibroblast growth factor 21 improves insulin sensitivity and synergizes with insulin in human adipose stem cell-derived (hASC adipocytes.

    Directory of Open Access Journals (Sweden)

    Darwin V Lee

    Full Text Available Fibroblast growth factor 21 (FGF21 has evolved as a major metabolic regulator, the pharmacological administration of which causes weight loss, insulin sensitivity and glucose control in rodents and humans. To understand the molecular mechanisms by which FGF21 exerts its metabolic effects, we developed a human in vitro model of adipocytes to examine crosstalk between FGF21 and insulin signaling. Human adipose stem cell-derived (hASC adipocytes were acutely treated with FGF21 alone, insulin alone, or in combination. Insulin signaling under these conditions was assessed by measuring tyrosine phosphorylation of insulin receptor (InsR, insulin receptor substrate-1 (IRS-1, and serine 473 phosphorylation of Akt, followed by a functional assay using 14C-2-deoxyglucose [14C]-2DG to measure glucose uptake in these cells. FGF21 alone caused a modest increase of glucose uptake, but treatment with FGF21 in combination with insulin had a synergistic effect on glucose uptake in these cells. The presence of FGF21 also effectively lowered the insulin concentration required to achieve the same level of glucose uptake compared to the absence of FGF21 by 10-fold. This acute effect of FGF21 on insulin signaling was not due to IR, IGF-1R, or IRS-1 activation. Moreover, we observed a substantial increase in basal S473-Akt phosphorylation by FGF21 alone, in contrast to the minimal shift in basal glucose uptake. Taken together, our data demonstrate that acute co-treatment of hASC-adipocytes with FGF21 and insulin can result in a synergistic improvement in glucose uptake. These effects were shown to occur at or downstream of Akt, or separate from the canonical insulin signaling pathway.

    Escherichia coli is a major environmental pathogen causing bovine mastitis, which leads to mammary tissue damage and cell death. We explored the effects of the probiotic Lactobacillus rhamnosus GR-1 on ameliorating E. coli-induced inflammation and cell damage in primary bovine mammary epithelial cells (BMECs). Increased Toll-like receptor 4 (TLR4), NOD1, and NOD2 mRNA expression was observed following E. coli challenge, but this increase was attenuated by L. rhamnosus GR-1 pretreatment. Immunofluorescence and Western blot analyses revealed that L. rhamnosus GR-1 pretreatment decreased the E. coli-induced increases in the expression of the NOD-like receptor family member pyrin domain-containing protein 3 (NLRP3) and the serine protease caspase 1. However, expression of the adaptor protein apoptosis-associated speck-like protein (ASC, encoded by the Pycard gene) was decreased during E. coli infection, even with L. rhamnosus GR-1 pretreatment. Pretreatment with L. rhamnosus GR-1 counteracted the E. coli-induced increases in interleukin-1β (IL-1β), -6, -8, and -18 and tumor necrosis factor alpha mRNA expression but upregulated IL-10 mRNA expression. Our data indicate that L. rhamnosus GR-1 reduces the adhesion of E. coli to BMECs, subsequently ameliorating E. coli-induced disruption of cellular morphology and ultrastructure and limiting detrimental inflammatory responses, partly via promoting TLR2 and NOD1 synergism and attenuating ASC-independent NLRP3 inflammasome activation. Although the residual pathogenic activity of L. rhamnosus, the dosage regimen, and the means of probiotic supplementation in cattle remain undefined, our data enhance our understanding of the mechanism of action of this candidate probiotic, allowing for development of specific probiotic-based therapies and strategies for preventing pathogenic infection of the bovine mammary gland.

    Full Text Available This paper concentrates on information disclosure regarding IAS 23, being included in accounting research field. It comprises an empirical study on the correlation between information published by companies in consolidated financial statements with respect to borrowing cost policies and a series of variables that characterize a firm. The objectives of this paper involve estimating and establishing an econometric model in which is assumed that disclosure index for information required by IAS 23 depends on certain elements in the form of country of origin, sales, total assets, debt ratio, ROA and ROE. International accounting literature presents a series of studies on the subject of compliance with IAS disclosure requirements. Similar with this paper, various authors considered annual reports as starting point for data gathering in their reasearch on disclosure phenomena. The criteria used for data gathering, processing and analysing have been previously used in a successful manner by important scientists who published in accounting field. The methodology used involves Disclosure Index computation, as well as SPSS data processing, analysis and interpretation of results. Results show that the model is valid, meaning that there is correlation between information disclosure with respect to IAS 23 and the analyzed variables. According to our estimated econometric model, most of the variables maintain a certain influence on disclosure as we can observe a significant correlation level between the studied elements. This research contributes to the development of both accounting field and international accounting literature, by studying borrowing costs disclosed information in relation to certain elements that best characterize the activity of a company. Although an empirical paper, it concentrates also on accounting practices, as it uses real data extracted from annual reports and consolidated financial statements.

    A lack of financial capability—financial opportunities and abilities—and poverty are highly interlinked. Over 65 percent of people in India are excluded from any financial services. This article explores income-poor Indians’ experiences with financial capability through a qualitative study. Purposive sampling was used to collect data from 658 individuals, through focus groups (n = 566) and face-to-face interviews (n = 92). Findings show that 97 percent of respondents had the opportunity to earn an income, and 55 percent earned through financial inclusion programs, but 87 percent of respondents earned less than U.S. $2 a day. Although almost all saved and needed to borrow, 46 percent were eligible for formal savings and only 23 percent for formal loans. Financial abilities or knowledge and skills related to income, savings, and loans were higher among the few who had a stable income or had medium and high income in relation to those who had unstable and low income. Respondents experienced many challenges with their financial capabilities, including borrowing to save, fearing formal loans, and lacking clarity about loan and interest rate; banks miscalculating interest rates; and political parties influencing access to loans. Implications for social policy and social work practice are discussed.

    The objective of the study is to provide global grids (0.5°) of revised annual coefficients for the Priestley-Taylor (P-T) and Hargreaves-Samani (H-S) evapotranspiration methods after calibration based on the ASCE (American Society of Civil Engineers)-standardized Penman-Monteith method (the ASCE method includes two reference crops: short-clipped grass and tall alfalfa). The analysis also includes the development of a global grid of revised annual coefficients for solar radiation (Rs) estimations using the respective Rs formula of H-S. The analysis was based on global gridded climatic data of the period 1950-2000. The method for deriving annual coefficients of the P-T and H-S methods was based on partial weighted averages (PWAs) of their mean monthly values. This method estimates the annual values considering the amplitude of the parameter under investigation (ETo and Rs) giving more weight to the monthly coefficients of the months with higher ETo values (or Rs values for the case of the H-S radiation formula). The method also eliminates the effect of unreasonably high or low monthly coefficients that may occur during periods where ETo and Rs fall below a specific threshold. The new coefficients were validated based on data from 140 stations located in various climatic zones of the USA and Australia with expanded observations up to 2016. The validation procedure for ETo estimations of the short reference crop showed that the P-T and H-S methods with the new revised coefficients outperformed the standard methods reducing the estimated root mean square error (RMSE) in ETo values by 40 and 25 %, respectively. The estimations of Rs using the H-S formula with revised coefficients reduced the RMSE by 28 % in comparison to the standard H-S formula. Finally, a raster database was built consisting of (a) global maps for the mean monthly ETo values estimated by ASCE-standardized method for both reference crops, (b) global maps for the revised annual coefficients of the P

    Full Text Available Multilateral development banks (MDBs play an important role in world economic processes and global economic governance. Since the establishment of the first multilateral development bank – the International Bank for Reconstruction and Development (IBRD – MDBs have emerged in three waves, each time as a response to the major changes in the world arena. The creation of the New Development Bank (NDB and the Asian Infrastructure Investment Bank (AIIB represents the third and latest wave of MDBs. These new development banks have arisen as a consequence of an historic shift in global economic power from developed countries to emerging economies and more specifically the increase in China’s economic might. This article traces the evolution of China’s participation in MDBs, characterizes various forms of China’s engagement with MDBs in specific periods of history, and explains Beijing’s motivation in establishing new MDBs. During almost 40 years of interaction with the multilateral development banks, China has made a great leap forward from large-borrower to creditor status, from ordinary member to the initiator and creator of new MDBs under its auspices. This article identifies the scale, composition and dynamic of MDBs’ assistance to China. It points out that despite its eye-catching economic achievements, China remains one of the largest borrowers from MDBs. Yet, in the process of China’s participation in MDBs there have been two turning points: in 2004–2005 when China became a creditor, and during the 2008 global financial crisis when China set a course to promote the reform of global governance system and the creation of new China-dominated financial bodies. The creation of new financial institutions is evaluated in the article as indicating Beijing’s foreign policy ambitions to assume a leadership role in the global economic architecture, while the fact that China is acting both as a creditor and a borrower in MDBs reflects the

    Full Text Available Neisseria gonorrhoeae (Ngo has developed multiple immune evasion mechanisms involving the innate and adaptive immune responses. Recent findings have reported that Ngo reduces the IL-1β secretion of infected human monocyte-derived macrophages (MDM. Here, we investigate the role of adenosine triphosphate (ATP in production and release of IL-1β in Ngo-infected MDM. We found that the exposure of Ngo-infected MDM to ATP increases IL-1β levels about ten times compared with unexposed Ngo-infected MDM (P0.05 and caspase-1 (CASP1, P>0.05. In addition, ATP was not able to modify caspase-1 activity in Ngo-infected MDM but was able to increase pyroptosis (P>0.01. Notably ATP treatment defined an increase of positive staining for IL-1β with a distinctive intracellular pattern of distribution. Collectively, these data demonstrate that ATP induces IL-1β secretion by a mechanism not related to the NLRP3/ASC/caspase-1 axis and likely is acting at the level of vesicle trafficking or pore formation.

    2013-01-01

    Full Text Available Traditional inventory models focus on operational decisions and inventory control. Quite few models consider the financial constraint and decision bias such as loss aversion, which are the reality in today's business environment, especially for the fashion and textiles industry. In this paper we study the inventory control problem for a loss-averse retailer with financial constraint for operations in a periodic review setting in a finite horizon. We characterize the optimal inventory control policies with self-financing or with borrowing as capital-dependent base-stock policies. We demonstrate with numerical examples that the optimal base-stock level is nonincreasing in the accumulated wealth and the loss-aversion indicator.

  13. The coherence lifetime-borrowing effect in vibronically coupled molecular aggregates under non-perturbative system-environment interactions.

    Science.gov (United States)

    Yeh, Shu-Hao; Engel, Gregory S.; Kais, Sabre

    Recently it has been suggested that the long-lived coherences in some photosynthetic pigment-protein systems, such as the Fenna-Matthews-Olson complex, could be attributed to the mixing of the pigments' electronic and vibrational degrees of freedom. In order to verify whether this is the case and to understand its underlying mechanism, a theoretical model capable of including both the electronic excitations and intramolecular vibrational modes of the pigments is necessary. Our model simultaneously considers the electronic and vibrational degrees of freedom, treating the system-environment interactions non-perturbatively by implementing the hierarchical equations of motion approach. Here we report the simulated two-dimensional electronic spectra of vibronically coupled molecular dimers to demonstrate how the electronic coherence lifetimes can be extended by borrowing the lifetime from the vibrational coherences.

  14. Government borrowing and the long-term interest rate: Application of an extended loanable funds model to the Slovak Republic

    Directory of Open Access Journals (Sweden)

    Hsing Yu

    2010-01-01

    Full Text Available Extending the open-economy loanable funds model, this paper finds that more government borrowing as a percent of GDP leads to a higher government bond yield, that a higher real money market rate, a higher expected inflation rate, a higher EU government bond yield, or a decrease in the Slovak nominal effective exchange rate would increase the Slovak government bond yield, and that the positive coefficient of the percent change in real GDP is insignificant at the 10% level. When the standard closedeconomy or open-economy loanable funds model is considered, except that the positive coefficient of the ratio of the net capital inflow to GDP is insignificant at the 10% level, other results are similar.

    Student loans are increasingly important and commonplace, especially among recent cohorts of young adults in the United States. These loans facilitate the acquisition of human capital in the form of education, but may also lead to stress and worries related to repayment. This study investigated two questions: 1) what is the association between the cumulative amount of student loans borrowed over the course of schooling and psychological functioning when individuals are 25-31 years old; and 2) what is the association between annual student loan borrowing and psychological functioning among currently enrolled college students? We also examined whether these relationships varied by parental wealth, college enrollment history (e.g. 2-year versus 4-year college), and educational attainment (for cumulative student loans only). We analyzed data from the National Longitudinal Survey of Youth 1997 (NLSY97), a nationally representative sample of young adults in the United States. Analyses employed multivariate linear regression and within-person fixed-effects models. Student loans were associated with poorer psychological functioning, adjusting for covariates, in both the multivariate linear regression and the within-person fixed effects models. This association varied by level of parental wealth in the multivariate linear regression models only, and did not vary by college enrollment history or educational attainment. The present findings raise novel questions for further research regarding student loan debt and the possible spillover effects on other life circumstances, such as occupational trajectories and health inequities. The study of student loans is even more timely and significant given the ongoing rise in the costs of higher education. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Bottom-mounted instrumentation was deployed at two sites on an ebb tidal delta to measure hydrodynamics, sediment transport, and seabed elevation. One site ('borrow site') was 2 km offshore and used as a dredging site for beach nourishment of nearby Hilton Head Island in South Carolina, and the other site ('reference site') was 10 km offshore and not directly impacted by the dredging. In-situ time-series data were collected during two periods after the dredging: March 15 - June 12, 2012('spring') and August 18 - November 18, 2012 ('fall'). At the reference site directional wave spectra and upper water column current velocities were measured, as well as high-resolution current velocity profiles and suspended sediment concentration profiles in the Bottom Boundary Layer (BBL). Seabed elevation and small-scale seabed changes were also measured. At the borrow site seabed elevation and near-bed wave and current velocities were collected using an Acoustic Doppler Velocimeter. Throughout both deployments bottom wave orbital velocities ranged from 0 - 110 m/s at the reference site. Wave orbital velocities were much lower at the borrow site ranging from 10-20 cm/s, as wave energy was dissipated on the extensive and rough sand banks before reaching the borrow site. Suspended sediment concentrations increased throughout the BBL when orbital velocities increased to approximately 20 cm/s. Sediment grain size and critical shear stresses were similar at both sites, therefore, re-suspension due to waves was less frequent at the borrow site. However, sediment concentrations were highly correlated with the tidal cycle at both sites. Semidiurnal tidal currents were similar at the two sites, typically ranging from 0 - 50 cm/s in the BBL. Maximum currents exceeded the critical shear stress and measured suspended sediment concentrations increased during the first hours of the tidal cycle when the tide switched to flood tide. Results indicate waves contributed more to sediment mobility at

    Full Text Available This study investigated in vitro effects of freshwater alga Cladophora glomerata water extract enriched during a biosorption process in Cr(III trivalent chromium and chromium picolinate on adipose-derived mesenchymal stromal stem cells (ASCs and extracellular microvesicles (MVs in equine metabolic syndrome-affected horses. Chemical characterisation of natural Cladophora glomerata was performed with special emphasis on: vitamin C, vitamin E, total phenols, fatty acids, free and protein-bound amino acids as well as measured Cr in algal biomass. To examine the influence of Cladophora glomerata water extracts, in vitro viability, oxidative stress factor accumulation, apoptosis, inflammatory response, biogenesis of mitochondria, autophagy in ASCs of EMS and secretory activity manifested by MV release were investigated. For this purpose, various methods of molecular biology and microscopic observations (i.e., immunofluorescence staining, SEM, TEM, FIB observations, mRNA and microRNA expression by RT-qPCR were applied. The extract of Cladophora glomerata enriched with Cr(III ions reduced apoptosis and inflammation in ASCs of EMS horses through improvement of mitochondrial dynamics, decreasing of PDK4 expression and reduction of endoplastic reticulum stress. Moreover, it was found, that Cladophora glomerata and Cr(III induce antioxidative protection coming from enhanced SOD activity Therefore, Cladophora glomerata enriched with Cr(III ions might become an interesting future therapeutic agent in the pharmacological treatment of EMS horses.

    Equine Metabolic Syndrome (EMS) is a steadily growing life-threatening endocrine disorder linked to insulin resistance, oxidative stress, and systemic inflammation. Inflammatory microenvironment of adipose tissue constitutes the direct tissue milieu for various cell populations, including adipose-derived mesenchymal stromal cells (ASCs), widely considered as a potential therapeutic cell source in the course of the treatment of metabolic disorders. Moreover, elevated oxidative stress induces inflammation in intestinal epithelial cells (IECs)-the first-line cells exposed to dietary compounds. In the conducted research, we showed that in vitro application of Spirulina platensis contributes to the restoration of ASCs' and IECs' morphology and function through the reduction of cellular oxidative stress and inflammation. Enhanced viability, suppressed senescence, and improved proliferation of ASCs and IECs isolated from metabolic syndrome-affected individuals were evident following exposition to Spirulina. A protective effect of the investigated extract against mitochondrial dysfunction and degeneration was also observed. Moreover, our data demonstrate that Spirulina extract effectively suppressed LPS-induced inflammatory responses in macrophages. In vivo studies showed that horses fed with a diet based on Spirulina platensis supplementation lost weight and their insulin sensitivity improved. Thus, our results indicate the engagement of Spirulina platensis nourishing as an interesting alternative approach for supporting the conventional treatment of equine metabolic syndrome.

    Full Text Available Polymeric biomaterials based on polyurethane and polylactide blends are promising candidates for regenerative medicine applications as biocompatible, bioresorbable carriers. In current research we showed that 80/20 polyurethane/polylactide blends (PU/PLDL with confirmed biological properties in vitro may be further improved by the addition of ZnO nanoparticles for the delivery of bioactive zinc oxide for cells. The PU/PLDL blends were doped with different concentrations of ZnO (0.001%, 0.01%, 0.05% and undertaken for in vitro biological evaluation using human adipose stromal stem cells (ASCs and olfactory ensheathing cells (OECs. The addition of 0.001% of ZnO to the biomaterials positively influenced the morphology, proliferation, and phenotype of cells cultured on the scaffolds. Moreover, the analysis of oxidative stress markers revealed that 0.001% of ZnO added to the material decreased the stress level in both cell lines. In addition, the levels of neural-specific genes were upregulated in OECs when cultured on sample 0.001 ZnO, while the apoptosis-related genes were downregulated in OECs and ASCs in the same group. Therefore, we showed that PU/PLDL blends doped with 0.001% of ZnO exert beneficial influence on ASCs and OECs in vitro and they may be considered for future applications in the field of regenerative medicine.

    The US Department of Energy is conducting cleanup operations at the Weldon Spring site, St. Charles, Missouri, that will include development of a 77-ha (191-acre) soil borrow area. Eight wetlands, including riverine and palustrine emergent wetland types and totaling 0.9 ha (2.2 acres), will be eliminated during excavation of the borrow area. A 23-ha (57-acre) wetland/shorebird complex will be created at the Busch Conservation Area. The complex will include 2 ha (5 acres) of palustrine emergent wetland as mitigation for wetland losses in the borrow area.

  12. Is Russia Too Unique to Learn From Abroad? Elite Views on Foreign Borrowing and the West, 1993-2012

    2016-01-01

    Full Text Available For more than two centuries, Russia has struggled to defi ne its historical-cultural relationship with the West, as its intellectual and political elites vigorously debated whether their country should emulate Europe or follow a distinct path of development. This article uses original elite survey data to examine these two propositions. The article reaches two conclusions. First, despite Russia’s long tradition of underscoring its uniqueness, close to three-quarters of Russian bureaucrats and Duma deputies in the mid-1990s were nonetheless willing to borrow from foreign experience, particularly from the models of European welfare capitalism. Second, despite the sharp rise in anti-Western sentiments emanating from the Kremlin over the past decade, as well as Vladimir Putin’s ever-growing emphasis on Russia’s distinctiveness, Russian elites are still surprisingly willing to adopt political and economic models from the West.

  13. A Calibrated Power Prior Approach to Borrow Information from Historical Data with Application to Biosimilar Clinical Trials.

    A biosimilar refers to a follow-on biologic intended to be approved for marketing based on biosimilarity to an existing patented biological product (i.e., the reference product). To develop a biosimilar product, it is essential to demonstrate biosimilarity between the follow-on biologic and the reference product, typically through two-arm randomization trials. We propose a Bayesian adaptive design for trials to evaluate biosimilar products. To take advantage of the abundant historical data on the efficacy of the reference product that is typically available at the time a biosimilar product is developed, we propose the calibrated power prior, which allows our design to adaptively borrow information from the historical data according to the congruence between the historical data and the new data collected from the current trial. We propose a new measure, the Bayesian biosimilarity index, to measure the similarity between the biosimilar and the reference product. During the trial, we evaluate the Bayesian biosimilarity index in a group sequential fashion based on the accumulating interim data, and stop the trial early once there is enough information to conclude or reject the similarity. Extensive simulation studies show that the proposed design has higher power than traditional designs. We applied the proposed design to a biosimilar trial for treating rheumatoid arthritis.

    Full Text Available A type III secretion system (T3SS in pathogenic Yersinia species functions to translocate Yop effectors, which modulate cytokine production and regulate cell death in macrophages. Distinct pathways of T3SS-dependent cell death and caspase-1 activation occur in Yersinia-infected macrophages. One pathway of cell death and caspase-1 activation in macrophages requires the effector YopJ. YopJ is an acetyltransferase that inactivates MAPK kinases and IKKβ to cause TLR4-dependent apoptosis in naïve macrophages. A YopJ isoform in Y. pestis KIM (YopJ(KIM has two amino acid substitutions, F177L and K206E, not present in YopJ proteins of Y. pseudotuberculosis and Y. pestis CO92. As compared to other YopJ isoforms, YopJ(KIM causes increased apoptosis, caspase-1 activation, and secretion of IL-1β in Yersinia-infected macrophages. The molecular basis for increased apoptosis and activation of caspase-1 by YopJ(KIM in Yersinia-infected macrophages was studied. Site directed mutagenesis showed that the F177L and K206E substitutions in YopJ(KIM were important for enhanced apoptosis, caspase-1 activation, and IL-1β secretion. As compared to YopJ(CO92, YopJ(KIM displayed an enhanced capacity to inhibit phosphorylation of IκB-α in macrophages and to bind IKKβ in vitro. YopJ(KIM also showed a moderately increased ability to inhibit phosphorylation of MAPKs. Increased caspase-1 cleavage and IL-1β secretion occurred in IKKβ-deficient macrophages infected with Y. pestis expressing YopJ(CO92, confirming that the NF-κB pathway can negatively regulate inflammasome activation. K+ efflux, NLRP3 and ASC were important for secretion of IL-1β in response to Y. pestis KIM infection as shown using macrophages lacking inflammasome components or by the addition of exogenous KCl. These data show that caspase-1 is activated in naïve macrophages in response to infection with a pathogen that inhibits IKKβ and MAPK kinases and induces TLR4-dependent apoptosis. This pro

    1980-10-01

    Private transfers of capital from the Organization of Petroleum Exporting Countries (OPEC) to developing countries are intended to complement private transfers from the Organization of Economic Cooperation and Development (OECD) by tapping the emerging capital markets in the Middle East. Developing countries will be able to diversify their borrowing and gain additional financing. The long-term investment of oil-producing countries will benefit and the pressures on the banking institutions to recycle funds will lessen. Middle East capital markets include international loans and international bonds. The history of the Kuwaiti dinar (KD) bond market, with its advantages for both investors and borrowers, illustrates the successful development of a capital market. Financial intermediation needs to be improved, however, if the Middle East is to become efficient enough to compete with the Euromarkets. Efficiency will require different measures and should reflect strengthening relationships among Middle East nations. (DCK)

  19. Budget-impact model for colonoscopy cost calculation and comparison between 2 litre PEG+ASC and sodium picosulphate with magnesium citrate or sodium phosphate oral bowel cleansing agents.

    2012-01-01

    With the availability of several bowel cleansing agents, physicians and hospitals performing colonoscopies will often base their choice of cleansing agent purely on acquisition cost. Therefore, an easy to use budget impact model has been developed and established as a tool to compare total colon preparation costs between different established bowel cleansing agents. The model was programmed in Excel and designed as a questionnaire evaluating information on treatment costs for a range of established bowel cleansing products. The sum of costs is based on National Health Service reference costs for bowel cleansing products. Estimations are made for savings achievable when using a 2-litre polyethylene glycol with ascorbate components solution (PEG+ASC) in place of other bowel cleansing solutions. Test data were entered into the model to confirm validity and sensitivity. The model was then applied to a set of audit cost data from a major hospital colonoscopy unit in the UK. Descriptive analysis of the test data showed that the main cost drivers in the colonoscopy process are the procedure costs and costs for bed days rather than drug acquisition costs, irrespective of the cleansing agent. Audit data from a colonoscopy unit in the UK confirmed the finding with a saving of £107,000 per year in favour of PEG+ASC when compared to sodium picosulphate with magnesium citrate solution (NaPic+MgCit). For every patient group the model calculated overall cost savings. This was irrespective of the higher drug expenditure associated with the use of PEG+ASC for bowel preparation. Savings were mainly realized through reduced costs for repeat colonoscopy procedures and associated costs, such as inpatient length of stay. The budget impact model demonstrated that the primary cost driver was the procedure cost for colonoscopy. Savings can be realized through the use of PEG+ASC despite higher drug acquisition costs relative to the comparator products. From a global hospital funding

The main stop-factors in a landing were formed in the article according to the procedure of the European Bank for Reconstruction and Development by the means of questioning the leading Russian banks that finance small-scale business. It is given the description of this method, also it is identified the main weaknesses of the EBRD methodology. There is a description of the main methods of the borrowing company’s analytical balance and thereupon it is made the conclusion about the necessity of the analysis of the balance’s principal factors across time. The analysis of indicators and factors in the dynamics enables us to see trends in the development of the company, and to identify deviations in the coefficients. Either materiality or difference from normal values of these coefficients may indicate the factors of the borrowers’ misconduct, and in particular it gives evidence concerning falsification of reports provided to a bank. There are stages of information processing for falsification’s detection, excluding the interest from decision-makers about the possibility of lending in the results of a transaction. The formula that determinates the value of net profit falsification has been made on basis of dynamic parameters of the analytical balance and the connection with the administrative profit-and-loss report. Further, the article provides the second method of a determination of the net profit falsification already based on data of the parameters in dynamics namely business profitability rate.

    To describe the dimensions of organisational culture within a selection of community pharmacies. Community pharmacy in the New Zealand primary care sector which is partially government funded and currently undergoing major reform. Community pharmacy is under pressure to take on new roles, integrate within the wider primary care team and deliver the expectations of contemporary health policy. The mixed methods approach of concept mapping was undertaken with 10 representatives from six community pharmacies selected as case sites. The process was split into three parts (a) face to face brainstorming to generate statements describing culture, followed by (b) statement reduction, piloting and approval of statement list by participants, followed by (c) sorting the statements into 'like' groups. Multidimensional scaling analysis of participant sorting allows the development of discrete clusters of statements that describe aspects of organizational culture. A set of 105 statements were generated at the brainstorming meeting. Eight clusters of organisational culture resulted from participant sorting: leadership and staff management; valuing each other and the team; free thinking, fun and open to challenge; trusted behaviour; customer relations; focus on external integration; providing systematic advice; embracing innovation. Community pharmacy is under pressure to take on new roles and deliver and there is some evidence organisational culture of pharmacy may be a barrier. Our paper outlines the development of a survey instrument for describing organisational culture through Concept mapping, a tool borrowed from social sciences. This tool can be used for exploration of aspects of culture that may be important in the change management process for improving the effectiveness of community pharmacy as expected by contemporary primary health care policy.

    Enterprises applying modeling and technological process management approaches represent a sector of a new innovative economic system. First of all, they are innovators using innovative proposals and various resources to solve practical problems. Their work leads to balanced positive technological changes. In other words, they constitute industrial entrepreneurship with innovative goals and vice versa - innovative entrepreneurship with industrial objectives. It should be noted that the mechanism of holistic management of technological processes at the enterprise combines a traditional industrial organization of production, an innovative and technological enterprise. The enterprise borrows industrial targets from the latter one, an innovative component - from innovative activity and entrepreneurial approaches to holistic management - from a commercial firm.

    Full Text Available After placing the general analytic framework associated with widely used quantitative macro indicators, this paper aims to analyse the fluctuating variables which can be influenced by the current accounts balance in the optimum external borrowing. The capacity of a country to service external debt depends on the growth of output and of exports and imports. Exports, minimum tolerable level of imports and foreign exchange rates (or reserves provide a useful framework for the examination of optimum external borrowing. So, the most widely used quantitative indicator here is the optimum external debt ratios, which is the ratios of debt service to the level of exports of goods and services. As a suggested, indicator of the optimum external debt burden in the medium-term or in the long run, the ratio of external debt to GNP (Gross National Product or of debt service to GNP may be superior to the ratio of debt service to exports because over time sizeable changes in the level of exports and imports in GNP can occur.

Para cada concentração de glicose foram criadas cinco alíquotas, adicionando-se uma solução de ácido ascórbico 200 mg/dl, suficiente para obter uma concentração final de ácido ascórbico de 20 mg/dl no primeiro tubo, de 50 mg/dl no segundo tubo, de 270 mg/dl no terceiro tubo, de 1.000 mg/dl no quarto tubo e de 2.000 mg/dl no quinto tubo. Após essa adição, as amostras foram novamente avaliadas no analisador Clinitek Atlas. RESULTADOS: Nas amostras com concentração de 20 mg/dl de ácido, não se evidenciou interferência. Nas concentrações iguais e acima de 50 mg/dl, a interferência do ácido ascórbico se fez presente, sendo que o fato foi caracterizado pelos resultados falso negativos para detecção da glicose urinária. CONCLUSÃO: Os resultados demonstraram a interferência do ácido ascórbico no método da química seca (tiras reagentes, subestimando o nível de glicose urinária.INTRODUCTION: Ascorbic acid (vitamin C is commonly used as a vitamin supplement. It is a water soluble vitamin, which is excreted through urine and may interfere in laboratory tests as well as redox reactions for urinary glucose detection. OBJECTIVE: This study aims to assess ascorbic acid interference in glycosuria detection by dry chemistry

  17. Formal Variability of Terms in the Sphere of Network Technologies

    Full Text Available The article addresses the problem of formal variability of terms in the sphere of network terminology in the Russian language. The research is based on data from the Internet communication in the sphere of network technologies. Such formal variability types as graphical, phonemic, word building and complex (graphic and phonetic, morphologic and accentual are discussed in this article. The authors reveal the reasons for graphic variability of foreign origin terms making up the international terminological fund. These reasons cover such aspects as the use of graphics of source language and recipient language; the presence or absence of hyphenation, etc. It is determined that the phonemic variants of terms appear as a result of oral or written borrowings. The existence of such variants is also connected with the stage of their adaptation in the Russian language after borrowing. In this case the variants are related with soft or hard pronunciation of consonants. There are also some cases of phonemic variability on the graphic level. The complex variability is regarded as a part of active processes taking place in the modern Russian language, and these processes involve both native and foreign origin terms. The particular attention is paid to the word-building variants – word-building affixes the variability of which is peculiar of network technologies. The results of the research show that the variability of professional units belonging to the network technologies sublanguage is caused by the active process of borrowing of specialpurpose vocabulary into the Russian language. The process is due to the intensification of intercultural communication in the professional spheres.

    Full Text Available Os objetivos neste estudo foram verificar se a própolis e o ácido ascórbico têm efeito sobre a integridade da membrana plasmática dos espermatozoides de caprinos e investigar o potencial desses antioxidantes no uso de meios diluidores de criopreservação de sêmen caprino. Foram utilizados cinco bodes adultos das raças Alpina (n = 2 e Saanen (n = 3. Após a coleta de sêmen, realizaram-se o exame físico do sêmen e morfológico dos espermatozoides, o teste supravital e o teste hiposmótico. Em seguida, o sêmen fresco foi diluído com o diluidor Bioxcell® (controle; Bioxcell® + 0,25% de extrato liofilizado de própolis; Bioxcell® + 0,5% de extrato liofilizado de própolis; Bioxcell® + 0,05% de ácido ascórbico; ou Bioxcell® + 0,25% de ácido ascórbico. Após as diluições finais, foram avaliados a motilidade e o vigor espermático obtidos com cada diluidor e posteriormente o sêmen foi submetido a envase, resfriamento e congelamento. No sêmen fresco, os aspectos físicos e morfológicos e os resultados dos testes supravital e hiposmótico não diferiram entre os animais nem entre raças. As médias gerais de motilidade e vigor espermático e dos testes supravital e hiposmótico obtidos logo após o descongelamento e após 3 horas de teste de termorresistência diferiram entre si, de modo que o diluidor contendo ácido ascórbico e o controle foram similares e superiores àqueles contendo própolis. O ácido ascórbico mantém a integridade estrutural da membrana dos espermatozoides durante o processo de criopreservação, bem como sua viabilidade após o teste de termorresistência, e pode ser uma alternativa na composição de diluentes para criopreservação de sêmen caprino; a própolis não é eficaz na manutenção da integridade e da viabilidade espermática pós-descongelamento e é tóxica aos espermatozoides nas concentrações de 0,25 e 0,5%.The objectives of this study were to verify whether propolis and ascorbic

    Weng, Weifeng

    This thesis presents papers on three areas of study within resource and environmental economics. "Demand Systems For Energy Forecasting" provides some practical considerations for estimating a Generalized Logit model. The main reason for using this demand system for energy and other factors is that the derived price elasticities are robust when expenditure shares are small. The primary objective of the paper is to determine the best form of the cross-price weights, and a simple inverse function of the expenditure share is selected. A second objective is to demonstrate that the estimated elasticities are sensitive to the units specified for the prices, and to show how price scales can be estimated as part of the model. "To Borrow or Not to Borrow: A Variation on the MacDougal-Kemp Theme" studies the impact of international capital movements on the conditional convergence of economies differing from each other only in initial wealth. We found that in assets, income, consumption and utility, convergence obtains, with and only with, the absence of international capital movement. When a rich country invests in a poor country, the balance of debt increases forever. Asset ownership is increased in all periods for the lender, and asset ownership of the borrower is deceased. Also, capital investment decreases the lender's utility for early periods, but increases it forever after a cross-over point. In contrast, the borrower's utility increases for early periods, but then decreases forever. "Valuing Reduced Risk for Households with Children or the Retired" presents a theoretical model of how families value risk and then exams family automobile purchases to impute the average Value of a Statistical Life (VSL) for each type of family. Data for fatal accidents are used to estimate survival rates for individuals in different types of accidents, and the probabilities of having accidents for different types of vehicle. These models are used to determine standardized risks for

    Full Text Available Throughout history, the Kyrgyz people borrowed many words and concepts especially on religion and ethics as a result of their relations with the Arabs and the Arabic language. They also borrowed many words of Persian origin on commerce, husbandry and agriculture from the Uzbek and Tajik peoples due to their relations with them in those fields. As a result of their close relations with the Russians which started in the tsar period, they not only made Russian as their official language and first language in their daily life due to the high pressure, but also borrowed many political, administrative, scientific and philosophical concepts from Russian, without phonetically changing many of them. Still geographically close to the Mongol and Chinese peoples, the Kyrgyz people got close to them, and even fought them in history. And as a result of such relations, they borrowed some words related to nomadic societies.This study aims to reveal changes in phonetics in the words borrowed by the Kyrgyz language from Arabic, Persian, Mongolian, Chinese and Russian in order to show the power of purification of the Kyrgyz language by means of examining its rules that it applies on borrowed words.

    Full Text Available Currently, equine metabolic syndrome (EMS, an endocrine disease linked to insulin resistance, affects an increasing number of horses. However, little is known about the effect of EMS on mesenchymal stem cells that reside in adipose tissue (ASC. Thus it is crucial to evaluate the viability and growth kinetics of these cells, particularly in terms of their application in regenerative medicine. In this study, we investigated the proliferative capacity, morphological features, and accumulation of oxidative stress factors in mesenchymal stem cells isolated from healthy animals (ASCN and horses suffering from EMS (ASCEMS. ASCEMS displayed senescent phenotype associated with β-galactosidase accumulation, enlarged cell bodies and nuclei, increased apoptosis, and reduced heterochromatin architecture. Moreover, we observed increased amounts of nitric oxide (NO and reactive oxygen species (ROS in these cells, accompanied by reduced superoxide dismutase (SOD activity. We also found in ASCEMS an elevated number of impaired mitochondria, characterized by membrane raptures, disarrayed cristae, and vacuole formation. Our results suggest that the toxic compounds, accumulating in the mitochondria under oxidative stress, lead to alternations in their morphology and may be partially responsible for the senescent phenotype and decreased proliferation potential of ASCEMS.

    Full Text Available O presente artigo busca analisar, a partir da obra clássica “A Ética Protestante e o Espírito do Capitalismo”, de Max Weber, como modalidades de conduta de vida e concepção de profissão foram adaptadas à peculiaridade do capitalismo ocidental moderno, erigindo as bases para a constituição de um novo ethos profissional. Trata-se, portanto, de investigar de que forma a doutrina calvinista da predestinação produziu elementos de estímulos psicológicos que fizeram com que indivíduos apresentassem ímpetos empreendedores voltados à acumulação racional de capital. Para tanto, foi feita uma revisão bibliográfica em torno de duas dimensões de análise da obra em questão: profissão como vocação e regimento ascético da conduta de vida. Ao fim e ao cabo, o estudo constatou que a educação religiosa para a ascese, reprovando o consumo e incentivando sua aplicação na produção, bem como legitimando o lucro econômico privado, implicou em efeitos significativos para o desencadeamento do capitalismo de tipo racional.

  4. THE USE OF ENGLISH-LOAN WORDS IN THE INFORMATION TECHNOLOGY DOMAIN

    Full Text Available This paper examines the phenomenon of linguistic borrowings in general and the use of anglicisms in particular, in the contexts of globalization and the progress made in different domains, especially in the Information Technology domain. Borrowing is the phenomenon which undertakes the word transmission process from one language into another among the connected communities. The language that lends is the donor or the borrower language, and the language that borrows is known as the receptor or the borrowing language. Anglicisms are the English-loan words that are present in many European languages. The phenomenon of globalisation is the main topic of several contradictory and polarization discussions and undoubtedly globalisation is necessary and it is a fact in today’s world but the question is: what will be the long-term language consequences? There might be two situations: the consequences may be positive, such as ease of communication and perception, language economics and also negative: not understanding anglicisms resulting in disturbed communication, rejection of anglicisms, loss of semantic diversity of your own language, less and less possibilities of expressing yourself in your own language. We can mention that responsible for the impact of English is the prestige associated with this language. This language is generally held in highest regard by the younger generation of Romanians, who are easily influenced by the television, radio, movies, and other media that are supplied by British and American entertainment, which are considered to be trendy and cool. Each of those resources has influenced the Romanian population on numerous levels, creating new words and phrases in the Romanian language. In order to illustrate and discuss the pertinent or, on the contrary, the unjustified use of English-loan words in the field of Information Technology, the study will focus on a selection of articles published in the electronic Romanian issues

O trabalho foi articulado a partir da participação de professores da ASCES em Grupo de Pesquisa da UFPE-CNPq e da percepção de como a integração das atividades institucionais poderiam melhorar os resultados e incluir um número maior de docentes, discentes e beneficiados, os reclusos e educadores do Sistema Penitenciário. As ações são realizadas quinzenalmente na unidade prisional, envolvendo ampla participação da sociedade civil; os trabalhos são apresentados em forma de encontros de formação com os professores, palestras e debates com os detentos e atividades mediadas por elementos lúdicos: imagens, fotografias, filmes, documentários, músicas, poesias. Os estudantes das duas instituições se integram sem competição, os professores recebem formação continuada e as atividades lúdicas com os detentos quebram a rotina da prisão e estimulam os detentos a se manter nas salas de aula, reduzindo a evasão. A atividade é utilizada como carga horária de estágio para os alunos da ASCES e como atividades complementares para os estudantes de Pedagogia, e permitem às duas instituições contribuir para a melhoria da qualidade de ensino na prisão. Essa atividade também estimula o convívio de estudantes de instituições distintas, incluindo estudantes de instituições que, inclusive, não são parceiras dos projetos, atraindo a participação de muitos voluntários e ex-alunos da ASCES e da Faculdade de Filosofia, Ciências e Letras de Caruaru (FAFICA.

Posteriormente, foram embaladas individualmente em dois tipos de embalagem de atmosfera modificada (CryovacÒ PD-900 e CryovacÒ PD-961. Goiabas sem embalagem e não tratadas com cálcio, mantidas à mesma temperatura de 8°C serviram como controle. Foram realizadas análises de perda de massa, acidez titulável, teores de sólidos solúveis totais e ácido ascórbico. Os frutos embalados apresentaram taxas de perda de massa menores que os sem embalagem (p<0,05. Os frutos tratados com cálcio não apresentaram diferença na taxa de degradação de ácido ascórbico em relação aos não tratados e os frutos embalados com PD-900 apresentaram retenção de ácido ascórbico maior. Após 4 semanas, as goiabas sem embalagem apresentaram-se impróprias para consumo, devido ao murchamento e ataque de fungos, enquanto que as embaladas estavam em bom estado. Após a sexta semana, apenas os frutos embalados com PD-900 sem tratamento com cálcio estavam próprios para consumo. A embalagem de atmosfera modificada reduziu a perda de massa e ácido ascórbico e prolongou a vida-de-prateleira do produto. O emprego de cálcio não afetou as características analisadas.

    Full Text Available O ácido ascórbico, vitamina C, é usado extensivamente na indústria de alimentos, não só devido ao seu valor nutricional, mas devido a suas contribuições funcionais na qualidade do produto. Existem muitos estudos sobre a estabilidade cinética do ácido ascórbico em bebidas, mas nenhum estudo foi encontrado sobre as constantes cinéticas de degradação do ácido ascórbico adicionado em purê de pêssego. Neste trabalho, estudou-se a cinética de degradação do ácido ascórbico em purê de pêssego da cultivar Jade, em condições anaeróbicas e na faixa de 70 a 90 °C. As concentrações de purês testadas foram 12, 22 e 32 °Brix. A análise cinética dos dados sugere que a degradação foi significativamente representada pelos modelos cinéticos de zero e primeira ordem. A velocidade de degradação do ácido ascórbico foi dependente da temperatura. A energia de ativação média foi de 45 kJ.mol-1 e independente da concentração de sólidos solúveis.Ascorbic acid (vitamin C is extensively used in the food industry, not only for its nutritional value, but also for its many functional contributions to product quality. There have been many studies on the stability of ascorbic acid in different beverages, but no study was found on the reaction rate constants for ascorbic acid degradation in peach purée. In this work, the degradation of ascorbic acid in Jade peach purée was studied in anaerobic conditions and from 70-90 °C. The peach purée concentrations tested were 12, 22 and 32 °Brix. The kinetic analysis of the data suggests that the degradation was significantly represented by zero and first-order kinetic models. The rate of ascorbic acid degradation in peach purée was temperature dependent. The average activation energy was 45 kJ.mol-1 and independent of the concentration of soluble solids.

    Pollutant emissions from aircraft in the vicinity of airports and at altitude are of great public concern due to their impact on environment and human health. The legislations aimed at limiting aircraft emissions have become more stringent over the past few decades. This has resulted in an urgent need to develop low emissions combustors in order to meet legislative requirements and reduce the impact of civil aviation on the environment. This article provides a comprehensive review of low emissions combustion technologies for modern aero gas turbines. The review considers current high Technologies Readiness Level (TRL) technologies including Rich-Burn Quick-quench Lean-burn (RQL), Double Annular Combustor (DAC), Twin Annular Premixing Swirler combustors (TAPS), Lean Direct Injection (LDI). It further reviews some of the advanced technologies at lower TRL. These include NASA multi-point LDI, Lean Premixed Prevaporised (LPP), Axially Staged Combustors (ASC) and Variable Geometry Combustors (VGC). The focus of the review is placed on working principles, a review of the key technologies (includes the key technology features, methods of realising the technology, associated technology advantages and design challenges, progress in development), technology application and emissions mitigation potential. The article concludes the technology review by providing a technology evaluation matrix based on a number of combustion performance criteria including altitude relight auto-ignition flashback, combustion stability, combustion efficiency, pressure loss, size and weight, liner life and exit temperature distribution.

One of the potential threats to patient safety is the sharing of medication among patients, which is a form of self-medication. This study analyzed experiences and attitudes of pain management physicians (PMPs about sharing prescription analgesics among patients.Methods: This qualitative study was conducted by semi-structured interviews among PMPs employed in Croatian pain clinics. The study involved two researchers and 15 PMPs.Results: Among PMPs, 80% have seen patients who share their prescription analgesics with other patients for whom prescription is not intended. Most PMPs consider prescription analgesics sharing a risky and negative behavior. Some of them, however, found certain positive aspects associated to it, such as being a benevolent behavior, helping patients to get medications when they need them, and helping them cope with pain.Conclusion: The majority of physicians specialized in pain management encountered patients sharing prescription analgesics. Most of them considered this as risky behavior with a number of potential consequences. It has been noted that this problem is neglected and that physicians should inquire about medication sharing. Direct-to-consumers advertising was perceived as a factor contributing to such behavior. Patient education and more involvement of physicians in identifying this behavior were cited as potential remedies for preventing sharing of prescription analgesics.

    Full Text Available Os programas de melhoramento genético de frangos de corte que buscam máxima velocidade de ganho de peso, alta eficiência alimentar, alta viabilidade, maior rendimento de carcaça e menor deposição de gordura podem desencadear algumas síndromes fisiológicas, dentre as quais destacam-se o estresse calórico, a morte súbita e a ascite. A ascite se enquadra no conceito das síndromes multifatoriais, uma vez que sua manifestação ocorre quando certos fatores genéticos e ambientais atuam em conjunto determinando o processo. As limitações anatômica e fisiológica da circulação sanguínea nos pulmões provocam a síndrome de hipertensão pulmonar (PHS; esta pode provocar grande acúmulo de fluido na cavidade abdominal, quadro este denominado de ascite. Ocorre redução da eficiência da circulação sangüínea, levando as aves à morte por hipóxia, predominantemente no período entre 30 e 40 dias de idade. Uma vez desencadeado o processo ascítico, a ave dificilmente é aproveitada no abate já que a mesma restringe o consumo de alimento, ganhando menos peso. Adicionalmente, a carcaça apresenta aumento do volume da cavidade abdominal e conseqüente congestão dos órgãos internos. A descrição da fisiologia, medidas de avaliação e perspectivas são apresentadas neste trabalho.Poultry genetic breeding programs which look for maximum weight gain, improved feed conversion, high viability, high carcass yield and low fat deposition may cause some physiologic syndromes, for example caloric stress, sudden death and ascites. Ascites is framed in concept of the multifactorial syndromes, once its manifestation happens when certain genetic and environment factors act together, determining the process. Anatomical and physiological limitations in blood circulation in the lungs give rise to pulmonary hypertension syndrome (PHS, producing great fluid accumulation in abdominal cavity, which is denominated ascites.

    Full Text Available Realizou-se a modelagem da degradação de vitamina C em ameixas desidratadas e submetidas a diferentes condições de temperatura e umidade relativa, com o auxílio da equação de Bigelow. As ameixas in natura foram liofilizadas e acondicionadas em dessecadores contendo diferentes soluções salinas saturadas na temperatura de 4ºC. Após atingir o equilíbrio, os dessecadores foram submetidos a temperaturas na faixa que variou entre 40 e 80ºC. A degradação de vitamina C foi analisada ao longo de 5 dias, aplicando-se o método de titulação com solução padronizada de 2,6-diclorofenolindofenol 0,01%. As amostras apresentaram os seguintes conteúdos de umidade: 0,05; 0,11; 0,18; 0,38 e 1,40g água/g sólido seco. A partir dos parâmetros da equação de Bigelow, tempo de redução decimal (D T e valor z, os resultados indicaram que as amostras submetidas à faixa de temperatura entre 40 - 60ºC apresentaram uma perda mais lenta de vitamina C (D T no conteúdo de umidade de 0,05 apresentou valores na faixa de 1672 - 275h. Por outro lado, em altas temperaturas a degradação do ácido ascórbico ocorreu mais rapidamente (D T para X = 0,05 forneceu valores entre 110 e 47h. Os parâmetros z e D T apresentaram uma dependência linear e quadrática com o conteúdo de umidade das amostras, respectivamente. De modo geral, em altos teores de umidade, houve uma maior perda de vitamina C, devido a sua alta solubilidade.The degradation of vitamin C in prunes submitted to different conditions of temperature and moisture content was modeling by using the Bigelow equation.

    Full Text Available Commercial cashew apple juice is widely accepted in the Brazilian market. Cashew apple has high content of ascorbic acid, an important nutrient to human beings. Ascorbic acid content in food can be affected by processing and storage conditions. Commercial cashew apple juice samples, ready-to-drink and concentrated, were analyzed. The ascorbic acid content, total titratable acidity, total soluble solids, and pH of the juices were determined during storage at 4 °C after the containers were opened. The ascorbic acid content presented a great variability among the samples analyzed ranging from 37.3 to 46.3 mg.100 mL-1 in ready-to-drink juices and from 75.7 to 152 mg.100 mL-1 in concentrated juices. The storage of commercial cashew apple juices for 48 hours at 4 °C resulted in ascorbic acid losses of up to 8.8% for concentrated and 6.4% for ready-to-drink juices. The other parameters remained stable during storage. The results of this study point to the importance of considering ascorbic acid losses in commercial cashew apple juices which occurs after opening but before the expiration date expires.Sucos de caju industrializados são amplamente aceitos no mercado brasileiro.

Sendo assim, objetivou-se avaliar a estabilidade do ácido ascórbico e pigmentos presentes no néctar de camu-camu, armazenados sob diferentes condições de luminosidade e temperatura. Os frutos foram despolpados e avaliados quanto às características físico-químicas. O néctar, obtido a partir da polpa, foi acondicionado em garrafas PET e armazenado em temperatura ambiente e sob refrigeração na presença e ausência de luz, sendo avaliado por 120 dias quanto à estabilidade de ácido ascórbico e antocianinas. O teor de ácido ascórbico nos néctares armazenados sob luz não diferiu estatisticamente dos armazenados protegidos da luz (343,25 e 340,48 mg.100 g -1, respectivamente, nos armazenados sob refrigeração, e (330,48 e 333,56 mg.100 g -1 nos armazenados em temperatura ambiente. Constatou-se que esta vitamina em néctares armazenados por 120 dias em temperatura de refrigeração apresentou boa estabilidade, com perda de apenas 12 a 14%. Quanto às antocianinas, a temperatura ambiente contribuiu negativamente, ocasionando uma degradação mais acelerada, no entanto, a exposição à luz não teve efeito. Nestas condições experimentais, conclui-se que o fator luminosidade tem pouca influência sobre o ácido ascórbico e antocianinas no néctar de camu-camu, e que a temperatura ambiente de armazenamento é fator negativo na estabilidade destes pigmentos.Camu-camu is a fruit with a remarkable nutritional potential due to its high ascorbic acid content.

    Full Text Available Temporal lobe epilepsy is the most common form of epilepsy in humans. Oxidative stress is a mechanism of cell death induced by seizures. Antioxidant compounds have neuroprotective effects due to their ability to inhibit free radical production. The objectives of this work were to comparatively study the inhibitory action of antioxidants (ascorbic acid or α-tocopherol on behavioral changes and brain damage induced by high doses of pilocarpine, aiming to further clarify the mechanism of action of these antioxidant compounds. In order to determinate neuroprotective effects, we studied the effects of ascorbic acid (250 or 500 mg/kg, i.p. and α-tocopherol (200 or 400 mg/kg, i.p. on the behavior and brain lesions observed after seizures induced by pilocarpine (400 mg/kg, i.p., P400 model in rats. Ascorbic acid or α-tocopherol injections prior to pilocarpine suppressed behavioral seizure episodes. These findings suggested that free radicals can be produced during brain damage induced by seizures. In the P400 model, ascorbic acid and α-tocopherol significantly decreased cerebral damage percentage. Antioxidant compounds can exert neuroprotective effects associated with inhibition of free radical production. These results highlighted the promising therapeutic potential of ascorbic acid and α-tocopherol in treatments for neurodegenerative diseases.A epilepsia de lobo temporal é a mais comum forma de epilepsia em humanos.

    Full Text Available Buriti do Brejo (Mauritia flexuosa L. é um típico fruto da Amazônia, Nordeste e Centro-Oeste brasileiro, muito utilizado na culinária para produção de sucos, doces e vinhos. É considerado uma excelente fonte de carotenóides precursores da vitamina A, apresentando maior concentração de β-caroteno. Além dos carotenóides também encontramos ácido ascórbico e açúcares. O ácido ascórbico administrado em quantidades suficientes pode prevenir os sinais clínicos de deficiência conhecida como escorbuto. O emprego da radiação ionizante gama tem mostrado um potencial efeito na redução de perdas pós-colheita, mantendo a qualidade nutricional dos alimentos. O presente trabalho teve como objetivo avaliar os efeitos da radiação gama, nas doses de 0,5 kGy e 1,0 kGy, na concentração de carotenóides totais, ácido ascórbico e açúcares do buriti. A determinação dos carotenos (α, β e luteína, ácido ascórbico e açúcares foi realizada por cromatografia líquida de alta eficiência (CLAE e os carotenóides totais por espectrofotometria. Os resultados demonstraram que o Buriti é uma excelente fonte de carotenóides totais (44600μg/100g, podendo ser utilizado no combate à hipovitaminose A. A irradiação dos frutos de buriti na dose de 0,5 kGy não alterou significativamente os teores de carotenóides e açúcares. Entretanto, houve uma redução na concentração do ácido ascórbico com o aumento da dose, que pode ter sido causada pela irradiação ou por fatores intrínsecos e extrínsecos que alteram a estabilidade do ácido ascórbico nos alimentos, podendo converter o ácido ascórbico a dehidroascórbico, mantendo ainda a forma ativa da vitamina C.Buriti (Mauritia flexuosa L., a typical fruit from the Northeast and Center-West Amazon of Brazil, is used in many regional dishes.

    The objective of this summer's work was to attempt to enhance Technology Application Group (TAG) ability to measure the outcomes of its efforts to transfer NASA technology. By reviewing existing literature, by explaining the economic principles involved in evaluating the economic impact of technology transfer, and by investigating the LaRC processes our William & Mary team has been able to lead this important discussion. In reviewing the existing literature, we identified many of the metrics that are currently being used in the area of technology transfer. Learning about the LaRC technology transfer processes and the metrics currently used to track the transfer process enabled us to compare other R&D facilities to LaRC. We discuss and diagram impacts of technology transfer in the short run and the long run. Significantly, it serves as the basis for analysis and provides guidance in thinking about what the measurement objectives ought to be. By focusing on the SBIR Program, valuable information regarding the strengths and weaknesses of this LaRC program are to be gained. A survey was developed to ask probing questions regarding SBIR contractors' experience with the program. Specifically we are interested in finding out whether the SBIR Program is accomplishing its mission, if the SBIR companies are providing the needed innovations specified by NASA and to what extent those innovations have led to commercial success. We also developed a survey to ask COTR's, who are NASA employees acting as technical advisors to the SBIR contractors, the same type of questions, evaluating the successes and problems with the SBIR Program as they see it. This survey was developed to be implemented interactively on computer. It is our hope that the statistical and econometric studies that can be done on the data collected from all of these sources will provide insight regarding the direction to take in developing systematic evaluations of programs like the SBIR Program so that they can

    The globalization of the economy and the end of the Cold War have triggered many changes in the traditional practices of U.S. industry. To effectively apply the resources available to the United States, the federal government has firmly advocated a policy of technology transfer between private industry and government labs, in this case the National Aeronautics and Space Administration (NASA). NASA Administrator Daniel Goldin is a strong proponent of this policy and has organized technology transfer or commercialization programs at each of the NASA field centers. Here at Langley Research Center, the Technology Applications Group (TAG) is responsible for facilitating the transfer of Langley developed research and technology to U.S. industry. Entering the program, I had many objectives for my summer research with TAG. Certainly, I wanted to gain a more thorough understanding of the concept of technology transfer and Langley's implementation of a system to promote it to both the Langley community and the community at large. Also, I hoped to become more familiar with Langley's research capabilities and technology inventory available to the public. More specifically, I wanted to learn about the technology transfer process at Langley. Because my mentor is a member of Materials and Manufacturing marketing sector of the Technology Transfer Team, another overriding objective for my research was to take advantage of his work and experience in materials research to learn about the Advanced Materials Research agency wide and help market these developments to private industry. Through the various projects I have been assigned to work on in TAG, I have successfully satisfied the majority of these objectives. Work on the Problem Statement Process for TAG as well as the development of the Advanced Materials Research Brochure have provided me with the opportunity to learn about the technology transfer process from the outside looking in and the inside looking out.

    The CEA is an organization with a primarily technological focus, and one of the key areas in which it carries out research is Health Technology. This field of research was recognized and approved by the French Atomic Energy Committee on July 20, 2004. The expectations of both the public and health care professionals relate to demands for the highest standards of health care, at minimum risk. This implies a need to diagnose illness and disease as accurately and as at early a stage as possible, to target surgery precisely to deal only with damaged organs or tissues, to minimize the risk of side effects, allergies and hospital-acquired infections, to follow-up and, as far as possible, tailor the health delivery system to each individual's needs and his or her lifestyle. The health care sector is subject to rapid changes and embraces a vast range of scientific fields. It now requires technological developments that will serve to gather increasing quantities of useful information, analyze and integrate it to obtain a full understanding of highly complex processes and to be able to treat the human body as un-invasively as possible. All the technologies developed require assessment, especially in the hospital environment. (authors)

It is experiencing rapid growth as concerns over fuel supplies and carbon emissions mean that governments and individuals are increasingly prepared to ignore its current high costs. It will become truly mainstream when its costs are comparable to other energy sources. At the moment, it is around four times too expensive for competitive commercial production. Three generations of photovoltaics have been envisaged that will take solar power into the mainstream. Currently, photovoltaic production is 90% first-generation and is based on silicon wafers. These devices are reliable and durable, but half of the cost is the silicon wafer and efficiencies are limited to around 20%. A second generation of solar cells would use cheap semiconductor thin films deposited on low-cost substrates to produce devices of slightly lower efficiency. A number of thin-film device technologies account for around 5-6% of the current market. As second-generation technology reduces the cost of active material, the substrate will eventually be the cost limit and higher efficiency will be needed to maintain the cost-reduction trend. Third-generation devices will use new technologies to produce high-efficiency devices. Advances in nanotechnology, photonics, optical metamaterials, plasmonics and semiconducting polymer sciences offer the prospect of cost-competitive photovoltaics. It is reasonable to expect that cost reductions, a move to second-generation technologies and the implementation of new technologies and third-generation concepts can lead to fully cost-competitive solar energy in 10-15 years.

  5. Vacuum Technology

    The environmental condition called vacuum is created any time the pressure of a gas is reduced compared to atmospheric pressure. On earth we typically create a vacuum by connecting a pump capable of moving gas to a relatively leak free vessel. Through operation of the gas pump the number of gas molecules per unit volume is decreased within the vessel. As soon as one creates a vacuum natural forces (in this case entropy) work to restore equilibrium pressure; the practical effect of this is that gas molecules attempt to enter the evacuated space by any means possible. It is useful to think of vacuum in terms of a gas at a pressure below atmospheric pressure. In even the best vacuum vessels ever created there are approximately 3,500,000 molecules of gas per cubic meter of volume remaining inside the vessel. The lowest pressure environment known is in interstellar space where there are approximately four molecules of gas per cubic meter. Researchers are currently developing vacuum technology components (pumps, gauges, valves, etc.) using micro electro mechanical systems (MEMS) technology. Miniature vacuum components and systems will open the possibility for significant savings in energy cost and will open the doors to advances in electronics, manufacturing and semiconductor fabrication. In conclusion, an understanding of the basic principles of vacuum technology as presented in this summary is essential for the successful execution of all projects that involve vacuum technology. Using the principles described above, a practitioner of vacuum technology can design a vacuum system that will achieve the project requirements.

    Full Text Available OBJETIVO: Testar se a suplementação com ácido ascórbico tem algum afeito citoprotetor em um modelo de cirrose biliar secundária em ratos jovens. MÉTODOS: Foram estudados 40 ratos Wistar desmamados no 21º dia pós-natal. Cada grupo de 10 foi submetido a um dos seguintes quatro tratamentos, até o 49º dia pós-natal, quando foram submetidos a eutanásia: 1 LC - ligadura dupla e ressecção do ducto biliar comum e administração diária de ácido ascórbico [100 mg/g de peso corporal (pc]; 2 LA - ligadura dupla e ressecção do ducto biliar comum e administração diária de veículo aquoso (1 mL/g pc; 3 SC - operação simulada e administração diária de ácido ascórbico (100 mg/g pc; 4 SA - ligadura dupla e ressecção do ducto biliar comum e administração diária de veículo aquoso (1 mL/g pc. Os ratos eram pesados diariamente. No 27º dia pós-operatório, eles receberam injeção intraperitoneal de 1,5 mg/g pc de pentobarbital sódico, e o tempo de sono induzido pelo pentobarbital foi medido. Coletou-se sangue para determinação de atividade sérica de alanina aminotransferase e de aspartato aminotransferase, níveis de albumina e globulina séricas, e o fígado foi analisado quanto à conteúdo de água e gordura. Os dados foram submetidos à ANOVA two-way, e comparações pareadas entre grupos foram testadas com o método de SNK. O nível de significância foi estabelecido em 0,05. RESULTADOS: A suplementação com ácido ascórbico atenuou os efeitos da colestase: reduziu o tempo de anestesia pelo pentobarbital, globulina sérica e o conteúdo de gordura no fígado. CONCLUSÕES: Nossos resultados corroboram a hipótese de que a suplementação com ácido ascórbico tem um efeito citoprotetor na cirrose biliar secundária.OBJECTIVE: To test whether ascorbic acid supplementation has any cytoprotective effect on a model of secondary biliary cirrhosis in young rats.

After the treatments all groups were observed for 24 h. Pilocarpine group presented seizures which progressed to status epilepticus in 75% of the animals. Pretreatment with AA led to a reduction of 50% of this rate. Results showed that pretreatment with AA did not alter reference memory when compared to a control group. In the working memory task, we observed a significant day's effect with important differences between control, pilocarpine and AA plus pilocarpine groups. Pilocarpine and AA plus pilocarpine groups had 81 and 16% of animals with brain injury, respectively. In the hippocampus of pilocarpine animals, it was detected an injury of 60%. As for the animals tested with AA plus pilocarpine, the hippocampal region of the group had a reduction of 43% in hippocampal lesion. Our findings suggest that seizures caused cognitive dysfunction and neuronal damage that might be related, at least in part, to the neurological problems presented by epileptic patients. AA can reverse cognitive dysfunction observed in rats with seizures as well as decrease neuronal injury in rat hippocampus.O objetivo do presente estudo foi avaliar o efeito neuroprotetor do ácido ascórbico (AA, contra o dano neuronal e o déficit de memória em ratos causados pelas convulsões.

The Underlying Technology Programme was set up to complement the fusion activities as well to develop technologies with a wider range of interest. The Technology Programme mainly involves staff from the Frascati laboratories of the Fusion Technical and Scientific Unit and from the Brasimone laboratories of the Advanced Physics Technologies Unit. Other ENEA units also provide valuable contributions to the programme. ENEA is heavily engaged in component development/testing and in design and safety activities for the European Fusion Technology Programme. Although the work documented in the following covers a large range of topics that differ considerably because they concern the development of extremely complex systems, the high level of integration and coordination ensures the capability to cover the fusion system as a whole. In 2004 the most significant testing activities concerned the ITER primary beryllium-coated first wall. In the field of high-heat-flux components, an important achievement was the qualification of the process for depositing a copper liner on carbon fibre composite (CFC) hollow tiles. This new process, pre-brazed casting (PBC), allows the hot radial pressing (HRP) joining procedure to be used also for CFC-based armour monoblock divertor components. The PBC and HRP processes are candidates for the construction of the ITER divertor. In the materials field an important milestone was the commissioning of a new facility for chemical vapour infiltration/deposition, used for optimising silicon carbide composite (SiCf/SiC) components. Eight patents were deposited during 2004

    The theme of the International Biohydrometallurgy Symposium held in Jackson Hole, Wyoming, August 22-25, 1993, is ''Biohydrometallurgy: An Industry Matures.'' This is a developing technology which made important contributions to the minerals industry. Biohydrometallurgical technology was first introduced into the copper industry and subsequently to the uranium industry for the production of metal values from low-grade mineral resources. Currently, biotechnology has advanced a step further. It is now commercially applied for the treatment of high-grade refractory gold ores in aerated stirred reactors to liberate precious metals for cyanidation. In addition, the industrial applications of biotechnology involve bioenhanced tertiary oil recovery processes, which contribute to an increase in oil production from previously exhausted wells. Furthermore, many bioremediation technologies are being developed for the removal of toxic heavy metals and radionuclides from contaminated soils and aqueous mining and industrial effluents. This volume contains papers selected for publication which are predominantly dealing with subjects related to laboratory and industrial scale bioleaching of base and precious metals, biocorrosion phenomena, diverse bioreduction processes and electrochemical reactions. Individual papers have been processed separately for inclusion in the appropriate data bases

  3. Structural modelling of economic growth: Technological changes

    Directory of Open Access Journals (Sweden)

    Sukharev Oleg

    2016-01-01

    Full Text Available Neoclassical and Keynesian theories of economic growth assume the use of Cobb-Douglas modified functions and other aggregate econometric approaches to growth dynamics modelling. In that case explanations of economic growth are based on the logic of the used mathematical ratios often including the ideas about aggregated values change and factors change a priori. The idea of assessment of factor productivity is the fundamental one among modern theories of economic growth. Nevertheless, structural parameters of economic system, institutions and technological changes are practically not considered within known approaches, though the latter is reflected in the changing parameters of production function. At the same time, on the one hand, the ratio of structural elements determines the future value of the total productivity of the factors and, on the other hand, strongly influences the rate of economic growth and its mode of innovative dynamics. To put structural parameters of economic system into growth models with the possibility of assessment of such modes under conditions of interaction of new and old combinations is an essential step in the development of the theory of economic growth/development. It allows forming stimulation policy of economic growth proceeding from the structural ratios and relations recognized for this economic system. It is most convenient in such models to use logistic functions demonstrating the resource change for old and new combination within the economic system. The result of economy development depends on starting conditions, and on institutional parameters of velocity change of resource borrowing in favour of a new combination and creation of its own resource. Model registration of the resource is carried out through the idea of investments into new and old combinations.

The Flight Deck of the Future is one element of the Integrated Power, Avionics, and Software (IPAS) facility, which, to a large extent, manages the F.F network and data systems. To date, integration with the Flight Deck of the Future has been limited by a lack of tools and understanding of the Flight Deck of the Future data handling systems. To remedy this problem it will be necessary to learn how data is managed in the Flight Deck of the Future and to develop tools or interfaces that enable easy integration of WEAR Lab and EV3 products into the Flight Deck of the Future mockups. This capability is critical to future prototype integration, evaluation, and demonstration. This will provide the ability for WEAR Lab products, EV3 human interface prototypes, and technologies from other JSC organizations to be evaluated and tested while in the Flight Deck of the Future. All WEAR Lab products must be integrated with the interface that will connect them to the Flight Deck of the Future. The WEAR Lab products will primarily be programmed in Arduino. Arduino will be used for the development of wearable controls and a tactile communication garment. Arduino will also be used in creating wearable methane detection and warning system.

    Full Text Available We are facing radical changes in our ways of living in the nearest future. Not necessarily of our own choice, but because tchnological development is moving so fast, that it will have still greater impact on many aspects of our lives. We have seen the beginnings of that change within the latest 35 years or so, but according to newest research that change will speed up immensely in the nearest years to come. The impact of that change or these changes will affect our working life immensely as a consequence of automation. How these changes are brought about and which are their consequences in a broad sense is being attempted to be understood and guessed by researchers. No one knows for sure, but specific patterns are visible. This paper will not try to guess, what will come, but will rather try to understand the deepest ”nature” of technology in order to understand the driving factors in this development: the genesis of technology in a broad sense in order to contibute to the understanding of the basis for the expected development.

    In recent days, energy security is becoming a major global concern and it has been recognized that a major reduction in greenhouse-gas emissions is required to combat climate change. Considerable expansion and new introduction of nuclear power generation are currently being planned and considered for the further in various parts of the world. Nuclear technologies of the latest 10 years in Japan were reviewed with their characteristics, advancement and future perspective. Steady efforts have been made to construct new nuclear power stations with computer-aided engineering system and modular and prefabricated structures, extend the interval of periodic inspections under the new inspection system that should improve both safety and reliability, implement advanced measures against aging and develop the next-generation light water reactors including a medium small reactor. Export of nuclear power plants has been promoted with international business alliance or cooperation. Activities to close nuclear fuel cycle to ensure sustainable nuclear energy utilization have been promoted. Decommissioning technologies for Tokai power station have been developed and accumulated know-how will be utilized in light water reactors. (T. Tanaka)

    Full Text Available Neste estudo, avaliou-se o efeito do tratamento térmico do suco de tangerina murcote em relação ao teor de carotenóides totais, ao perfil de carotenóides (luteína, zeaxantina, β-criptoxantina e β-caroteno, aos compostos fenólicos totais, ao ácido ascórbico e à capacidade antioxidante. No processo, utilizou-se um trocador de calor tubular, sendo avaliados 11 tratamentos seguindo um ensaio fatorial completo 2² com três repetições no ponto central, com quatro pontos axiais e uma região de observação de 88 a 100 ºC e 16 a 44 s. O teor de caratenóides totais decresceu de forma significativa em quase todos os tratamentos aplicados, se comparado ao valor encontrado para o suco in natura. A maioria dos tratamentos não reduziu de forma significativa os teores dos caratenóides luteína, zeaxantina e β-criptoxantina. Além disso, o teor de β-caroteno não sofreu alterações significativas em todos os tratamentos avaliados. A análise de variância mostrou que, para os caratenóides, não ocorreram interações significativas entre as variáveis temperatura e tempo. Os teores de ácido ascórbico e compostos fenólicos totais apresentaram reduções em seis condições avaliadas, ao passo que, em quatro, observou-se um aumento dos teores de compostos fenólicos totais, causado provavelmente pela evaporação da água presente no suco. A maior redução do teor de ácido ascórbico e o maior aumento para compostos fenólicos totais foi observado para o binômio 100 ºC/30 s. O teor de ácido ascórbico sofreu de forma significativa a influência da temperatura e esse processo de degradação pode ser descrito por meio de um modelo quadrático. Todos os tratamentos utilizados reduziram a capacidade antioxidante do suco, sendo mais intensa para o binômio 100 ºC/30 s. As variações observadas não alteraram de maneira considerável as características nutricionais do suco e os tratamentos térmicos realizados a 94 ºC por 16 a 44 s

    Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

    A question of the 1980s is how will contraceptive technology contribute to improving family planning services to meet the goal of making available a simple, safe, effective, and widely acceptable contraceptive method. Significant changes in existing technology in the 1970s resulted in safer and more effective contraceptive methods. Voluntary sterilization emerged as the primary method in developed and developing countries, as important modifications simplified the procedure for women. The tolerance and effectiveness of the IUD were improved by reducing its size, adding copper to its surface, or encapsulating progesterone within it. The steroid content of the birth control pill was reduced 10-fold, leading to fewer side effects, and the pill was found to be an effective postcoital contraceptive when taken at specific intervals. Vacuum aspiration for the termination of 1st trimester pregnancy proved to be 1 of the safest surgical techniques practiced. Belated attention is now being focused on adapting existing contraceptive methods for use during the postpartum period and breast feeding. The insertion of an IUD immediately following childbirth is a particularly useful option in the developing world as an increasing number of women have their babies in urban hospitals. A method of enhancing the contraceptive effect of breast feeding should neither change milk production nor transfer the drug to the nursing infant. Fortunately, progestin-only pills have been found to have no effect on breast milk and an attempt is being made to expand the use of this approved method. More simplification of female sterilization is needed. Current techniques require back-up facilities in case of complications and are unlikely to meet the developing world's enormous demand. 2 methods not widely used -- spermicides and periodic abstinence -- are coming under new scrutiny. In mid-1983 the US Food and Drug Administration approved a spermicide-impregnanated disposable sponge for over

    This paper addressed the issue of how the petroleum industry can prepare itself with regards to the imminent changes in communication mechanisms as the Internet and World-Wide-Web are being accepted as the norm for all technical and scientific information services. In particular, the paper focused on new technologies for data acquisition, well site monitoring and data analysis where information is gathered from a remote site to the office. The paper also reviewed modeling concepts which show that secure and dependable data communications can disseminate information to personnel within an organization to make informed decisions and reduce response time. The topic is particularly relevant to the petroleum industry as fluctuations in oil and gas pricing, global competition, environmental policy, and government monetary and fiscal policy have forced companies to change the way they conduct business. Security issues associated with data communication were also addressed. 3 refs., 6 figs.

    Waste incineration is the art of completely combusting waste, while maintaining or reducing emission levels below current emission standards. Where possible, objectives include the recovering of energy as well as the  combustion residues.  Successful waste incineration makes it possible to achieve a deep reduction in waste volume, obtain a compact and sterile residue, and eliminate a wide array of pollutants. This book places waste incineration within the wider context of waste management, and demonstrates that, in contrast to landfills and composting, waste incineration can eliminate objectionable and hazardous properties such as flammability and toxicity, result in a significant reduction in volume, and destroy gaseous and liquid waste streams leaving little or no residues beyond those linked to flue gas neutralization and treatment. Moreover, waste incineration sterilizes and destroys putrescible matter, and produces usable heat.  Incineration Technologies first appeared as a peer-reviewed contribution ...

    Powder technology is experiencing nowadays a great development and has broad application in different fields: nuclear energy, medicine, new energy sources, industrial and home artifacts, etc. Ceramic materials are of daily use as tableware and also in the building industry (bricks, tiles, etc.). However, in machine construction its utilization is not so common. The same happens with metals: powder metallurgy is employed less than traditional metal forming techniques. Both cases deal with powder technology and the forming techniques as far as the final consolidation through sintering processes are very similar. There are many different methods and techniques in the forming stage: cold-pressing, slip casting, injection molding, extrusion molding, isostatic pressing, hot-pressing (which involves also the final consolidation step), etc. This variety allows to obtain almost any desired form no matter how complex it could be. Some applications are very specific as in the case of UO 2 pellets (used as nuclear fuels) but with the same technique and other materials, it is possible to manufacture a great number of different products. This work shows the characteristics and behaviour of two magnetic ceramic materials (ferrites) fabricated in the laboratory of the Applied Research Division of the Bariloche Atomic Center for different purposes. Other materials and products made with the same method are also mentioned. Likewise, densities and shrinkage obtained by different methods of forming (cold-pressing, injection molding, slip casting and extrusion molding) using high-purity alumina (99.5% Al 2 O 3 ). Finally, different applications of such methods are given. (Author) [es

    Since 2006 NASA has been formulating robotic missions to the lunar surface through programs and projects like the Robotic Lunar Exploration Program, Lunar Precursor Robotic Program, and International Lunar Network. All of these were led by NASA Marshall Space Flight Center (MSFC). Due to funding shortfalls, the lunar missions associated with these efforts, the designs, were not completed. From 2010 to 2013, the Robotic Lunar Lander Development Activity was funded by the Science Mission Directorate (SMD) to develop technologies that would enable and enhance robotic lunar surface missions at lower costs. In 2013, a requirements-driven, low-cost robotic lunar lander concept was developed for the Resource Prospector Mission. Beginning in 2014, The Advanced Exploration Systems funded the lander team and established the MSFC, Johnson Space Center, Applied Physics Laboratory, and the Jet Propulsion Laboratory team with MSFC leading the project. The lander concept to place a 300-kg rover on the lunar surface has been described in the New Technology Report Case Number MFS-33238-1. A low-cost lander concept for placing a robotic payload on the lunar surface is shown in figures 1 and 2. The NASA lander team has developed several lander concepts using common hardware and software to allow the lander to be configured for a specific mission need. In addition, the team began to transition lander expertise to United States (U.S.) industry to encourage the commercialization of space, specifically the lunar surface. The Lunar Cargo Transportation and Landing by Soft Touchdown (CATALYST) initiative was started and the NASA lander team listed above is partnering with three competitively selected U.S. companies (Astrobotic, Masten Space Systems, and Moon Express) to develop, test, and operate their lunar landers.

    The Kilopower project aims to develop and demonstrate scalable fission-based power technology for systems capable of delivering 110 kW of electric power with a specific power ranging from 2.5 - 6.5 Wkg. This technology could enable high power science missions or could be used to provide surface power for manned missions to the Moon or Mars. NASA has partnered with the Department of Energys National Nuclear Security Administration, Los Alamos National Labs, and Y-12 National Security Complex to develop and test a prototypic reactor and power system using existing facilities and infrastructure. This technology demonstration, referred to as the Kilowatt Reactor Using Stirling TechnologY (KRUSTY), will undergo nuclear ground testing in the summer of 2017 at the Nevada Test Site. The 1 kWe variation of the Kilopower system was chosen for the KRUSTY demonstration. The concept for the 1 kWe flight system consist of a 4 kWt highly enriched Uranium-Molybdenum reactor operating at 800 degrees Celsius coupled to sodium heat pipes. The heat pipes deliver heat to the hot ends of eight 125 W Stirling convertors producing a net electrical output of 1 kW. Waste heat is rejected using titanium-water heat pipes coupled to carbon composite radiator panels. The KRUSTY test, based on this design, uses a prototypic highly enriched uranium-molybdenum core coupled to prototypic sodium heat pipes. The heat pipes transfer heat to two Advanced Stirling Convertors (ASC-E2s) and six thermal simulators, which simulate the thermal draw of full scale power conversion units. Thermal simulators and Stirling engines are gas cooled. The most recent project milestone was the completion of non-nuclear system level testing using an electrically heated depleted uranium (non-fissioning) reactor core simulator. System level testing at the Glenn Research Center (GRC) has validated performance predictions and has demonstrated system level operation and control in a test configuration that replicates the one

    The technology activities carried out by the EURATOM-ENEA Association concern the continuation of the European Fusion Development Agreement (EFDA) as well as the ITER activities coordinated by the ITER International Office and Fusion for Energy. Also included in the activities are design and RD under the Broader Approach Agreement between the EU and Japan. In order to better contribute to the programme a number of consortium agreements among the Associations are being signed. Collaboration with industries in view of their participation in the construction of ITER was further strengthened, mainly in the field of magnet and divertor components. The new European Test Blanket Facility at ENEA Brasimone was completed; the design of the ITER radial neutron camera was optimised and the performance achievable with the in-vessel viewing system was further assessed by experimental trials. Design activities for the JT-60SA magnet and power supply system as well as the design and experimental activities related to the target of the International Fusion Materials Irradiation Facility were continued. Significant work was done to define quality assurance for neutronics analyses. Mockups of the ITER pre-compression ring made in glass fibre epoxy were tested. The activities and results documented in the following illustrate ENEA's efforts to support fusion development
