  2. Software engineering capability for Ada (GRASP/Ada Tool)

    Cross, James H., II

    1995-01-01

    The GRASP/Ada project (Graphical Representations of Algorithms, Structures, and Processes for Ada) has successfully created and prototyped a new algorithmic level graphical representation for Ada software, the Control Structure Diagram (CSD). The primary impetus for creation of the CSD was to improve the comprehension efficiency of Ada software and, as a result, improve reliability and reduce costs. The emphasis has been on the automatic generation of the CSD from Ada PDL or source code to support reverse engineering and maintenance. The CSD has the potential to replace traditional prettyprinted Ada Source code. A new Motif compliant graphical user interface has been developed for the GRASP/Ada prototype.

  3. ADAS Update and Maintainability

    Watson, Leela R.

    2010-01-01

    Since 2000, both the National Weather Service Melbourne (NWS MLB) and the Spaceflight Meteorology Group (SMG) have used a local data integration system (LOIS) as part of their forecast and warning operations. The original LOIS was developed by the Applied Meteorology Unit (AMU) in 1998 (Manobianco and Case 1998) and has undergone subsequent improvements. Each has benefited from three-dimensional (3-D) analyses that are delivered to forecasters every 15 minutes across the peninsula of Florida. The intent is to generate products that enhance short-range weather forecasts issued in support of NWS MLB and SMG operational requirements within East Central Florida. The current LDIS uses the Advanced Regional Prediction System (ARPS) Data Analysis System (AD AS) package as its core, which integrates a wide variety of national, regional, and local observational data sets. It assimilates all available real-time data within its domain and is run at a finer spatial and temporal resolution than current national or regional-scale analysis packages. As such, it provides local forecasters with a more comprehensive understanding of evolving fine-scale weather features. Over the years, the LDIS has become problematic to maintain since it depends on AMU-developed shell scripts that were written for an earlier version of the ADAS software. The goals of this task were to update the NWS MLB/SMG LDIS with the latest version of ADAS, incorporate new sources of observational data, and upgrade and modify the AMU-developed shell scripts written to govern the system. In addition, the previously developed ADAS graphical user interface (GUI) was updated. Operationally, these upgrades will result in more accurate depictions of the current local environment to help with short-range weather forecasting applications, while also offering an improved initialization for local versions of the Weather Research and Forecasting (WRF) model used by both groups.

  5. Using Ada: The deeper challenges

    Feinberg, David A.

    1986-01-01

    The Ada programming language and the associated Ada Programming Support Environment (APSE) and Ada Run Time Environment (ARTE) provide the potential for significant life-cycle cost reductions in computer software development and maintenance activities. The Ada programming language itself is standardized, trademarked, and controlled via formal validation procedures. Though compilers are not yet production-ready as most would desire, the technology for constructing them is sufficiently well known and understood that time and money should suffice to correct current deficiencies. The APSE and ARTE are, on the other hand, significantly newer issues within most software development and maintenance efforts. Currently, APSE and ARTE are highly dependent on differing implementer concepts, strategies, and market objectives. Complex and sophisticated mission-critical computing systems require the use of a complete Ada-based capability, not just the programming language itself; yet the range of APSE and ARTE features which must actually be utilized can vary significantly from one system to another. As a consequence, the need to understand, objectively evaluate, and select differing APSE and ARTE capabilities and features is critical to the effective use of Ada and the life-cycle efficiencies it is intended to promote. It is the selection, collection, and understanding of APSE and ARTE which provide the deeper challenges of using Ada for real-life mission-critical computing systems. Some of the current issues which must be clarified, often on a case-by-case basis, in order to successfully realize the full capabilities of Ada are discussed.

  6. Ada Structure Design Language (ASDL)

    Chedrawi, Lutfi

    1986-01-01

    An artist acquires all the necessary tools before painting a scene. In the same analogy, a software engineer needs the necessary tools to provide their design with the proper means for implementation. Ada provide these tools. Yet, as an artist's painting needs a brochure to accompany it for further explanation of the scene, an Ada design also needs a document along with it to show the design in its detailed structure and hierarchical order. Ada could be self-explanatory in small programs not exceeding fifty lines of code in length. But, in a large environment, ranging from thousands of lines and above, Ada programs need to be well documented to be preserved and maintained. The language used to specify an Ada document is called Ada Structure Design Language (ASDL). This language sets some rules to help derive a well formatted Ada detailed design document. The rules are defined to meet the needs of a project manager, a maintenance team, a programmer and a systems designer. The design document templates, the document extractor, and the rules set forth by the ASDL are explained in detail.

  7. Update of GRASP/Ada reverse engineering tools for Ada

    Cross, James H., II

    1993-01-01

    The GRASP/Ada project (Graphical Representations of Algorithms, Structures, and Processes for Ada) successfully created and prototyped a new algorithmic level graphical representation for Ada software, the Control Structure Diagram (CSD). The primary impetus for creation of the CSD was to improve the comprehension efficiency of Ada software and, as a result, improve reliability and reduce costs. The emphasis was on the automatic generation of the CSD from Ada PDL or source code to support reverse engineering and maintenance. The CSD has the potential to replace traditional pretty printed Ada source code. In Phase 1 of the GRASP/Ada project, the CSD graphical constructs were created and applied manually to several small Ada programs. A prototype CSD generator (Version 1) was designed and implemented using FLEX and BISON running under VMS on a VAX 11-780. In Phase 2, the prototype was improved and ported to the Sun 4 platform under UNIX. A user interface was designed and partially implemented using the HP widget toolkit and the X Windows System. In Phase 3, the user interface was extensively reworked using the Athena widget toolkit and X Windows. The prototype was applied successfully to numerous Ada programs ranging in size from several hundred to several thousand lines of source code. Following Phase 3,e two update phases were completed. Update'92 focused on the initial analysis of evaluation data collected from software engineering students at Auburn University and the addition of significant enhancements to the user interface. Update'93 (the current update) focused on the statistical analysis of the data collected in the previous update and preparation of Version 3.4 of the prototype for limited distribution to facilitate further evaluation. The current prototype provides the capability for the user to generate CSD's from Ada PDL or source code in a reverse engineering as well as forward engineering mode with a level of flexibility suitable for practical

  8. Ada Linear-Algebra Program

    Klumpp, A. R.; Lawson, C. L.

    1988-01-01

  9. GRASP/Ada 95: Reverse Engineering Tools for Ada

    Cross, James H., II

    1996-01-01

    The GRASP/Ada project (Graphical Representations of Algorithms, Structures, and Processes for Ada) has successfully created and prototyped an algorithmic level graphical representation for Ada software, the Control Structure Diagram (CSD), and a new visualization for a fine-grained complexity metric called the Complexity Profile Graph (CPG). By synchronizing the CSD and the CPG, the CSD view of control structure, nesting, and source code is directly linked to the corresponding visualization of statement level complexity in the CPG. GRASP has been integrated with GNAT, the GNU Ada 95 Translator to provide a comprehensive graphical user interface and development environment for Ada 95. The user may view, edit, print, and compile source code as a CSD with no discernible addition to storage or computational overhead. The primary impetus for creation of the CSD was to improve the comprehension efficiency of Ada software and, as a result, improve reliability and reduce costs. The emphasis has been on the automatic generation of the CSD from Ada 95 source code to support reverse engineering and maintenance. The CSD has the potential to replace traditional prettyprinted Ada source code. The current update has focused on the design and implementation of a new Motif compliant user interface, and a new CSD generator consisting of a tagger and renderer. The Complexity Profile Graph (CPG) is based on a set of functions that describes the context, content, and the scaling for complexity on a statement by statement basis. When combined graphicafly, the result is a composite profile of complexity for the program unit. Ongoing research includes the development and refinement of the associated functions, and the development of the CPG generator prototype. The current Version 5.0 prototype provides the capability for the user to generate CSDs and CPGs from Ada 95 source code in a reverse engineering as well as forward engineering mode with a level of flexibility suitable for

  10. Multiprocessor performance modeling with ADAS

    Hayes, Paul J.; Andrews, Asa M.

    1989-01-01

    A graph managing strategy referred to as the Algorithm to Architecture Mapping Model (ATAMM) appears useful for the time-optimized execution of application algorithm graphs in embedded multiprocessors and for the performance prediction of graph designs. This paper reports the modeling of ATAMM in the Architecture Design and Assessment System (ADAS) to make an independent verification of ATAMM's performance prediction capability and to provide a user framework for the evaluation of arbitrary algorithm graphs. Following an overview of ATAMM and its major functional rules are descriptions of the ADAS model of ATAMM, methods to enter an arbitrary graph into the model, and techniques to analyze the simulation results. The performance of a 7-node graph example is evaluated using the ADAS model and verifies the ATAMM concept by substantiating previously published performance results.

  11. Parallel Programming with Declarative Ada

    Thornley, John

    1993-01-01

    Declarative programming languages (e.g., functional and logic programming languages) are semantically elegant and implicitly express parallelism at a high level. We show how a parallel declarative language can be based on a modern structured imperative language with single-assignment variables. Such a language combines the advantages of parallel declarative programming with the strengths and familiarity of the underlying imperative language. We introduce Declarative Ada, a parallel declarativ...

  14. Experiences with Ada in an embedded system

    Labaugh, Robert J.

    1988-01-01

    Recent experiences with using Ada in a real time environment are described. The application was the control system for an experimental robotic arm. The objectives of the effort were to experiment with developing embedded applications in Ada, evaluating the suitability of the language for the application, and determining the performance of the system. Additional objectives were to develop a control system based on the NASA/NBS Standard Reference Model for Telerobot Control System Architecture (NASREM) in Ada, and to experiment with the control laws and how to incorporate them into the NASREM architecture.

    2013-01-01

    Ada has an important role in the real-time/embedded/safety-critical areas. It is the only ISO-standard, object-oriented, concurrent, real-time programming language. Ada is used as a usual language for application areas such as defense embedded systems that reliability and efficiency are very essential. One of the main Ada’s characteristics in compare with other programming languages is that, Ada was developed from the ground up with capabilities that provide real-time requirements. In this st...

  16. Software engineering and Ada in design

    Oneill, Don

    1986-01-01

    Modern software engineering promises significant reductions in software costs and improvements in software quality. The Ada language is the focus for these software methodology and tool improvements. The IBM FSD approach, including the software engineering practices that guide the systematic design and development of software products and the management of the software process are examined. The revised Ada design language adaptation is revealed. This four level design methodology is detailed including the purpose of each level, the management strategy that integrates the software design activity with the program milestones, and the technical strategy that maps the Ada constructs to each level of design. A complete description of each design level is provided along with specific design language recording guidelines for each level. Finally, some testimony is offered on education, tools, architecture, and metrics resulting from project use of the four level Ada design language adaptation.

  17. An Embedded Rule-Based Diagnostic Expert System in Ada

    Jones, Robert E.; Liberman, Eugene M.

    1992-01-01

    Ada is becoming an increasingly popular programming language for large Government-funded software projects. Ada with it portability, transportability, and maintainability lends itself well to today's complex programming environment. In addition, expert systems have also assumed a growing role in providing human-like reasoning capability expertise for computer systems. The integration is discussed of expert system technology with Ada programming language, especially a rule-based expert system using an ART-Ada (Automated Reasoning Tool for Ada) system shell. NASA Lewis was chosen as a beta test site for ART-Ada. The test was conducted by implementing the existing Autonomous Power EXpert System (APEX), a Lisp-based power expert system, in ART-Ada. Three components, the rule-based expert systems, a graphics user interface, and communications software make up SMART-Ada (Systems fault Management with ART-Ada). The rules were written in the ART-Ada development environment and converted to Ada source code. The graphics interface was developed with the Transportable Application Environment (TAE) Plus, which generates Ada source code to control graphics images. SMART-Ada communicates with a remote host to obtain either simulated or real data. The Ada source code generated with ART-Ada, TAE Plus, and communications code was incorporated into an Ada expert system that reads the data from a power distribution test bed, applies the rule to determine a fault, if one exists, and graphically displays it on the screen. The main objective, to conduct a beta test on the ART-Ada rule-based expert system shell, was achieved. The system is operational. New Ada tools will assist in future successful projects. ART-Ada is one such tool and is a viable alternative to the straight Ada code when an application requires a rule-based or knowledge-based approach.

  18. An Ada inference engine for expert systems

    Lavallee, David B.

    1986-01-01

    The purpose is to investigate the feasibility of using Ada for rule-based expert systems with real-time performance requirements. This includes exploring the Ada features which give improved performance to expert systems as well as optimizing the tradeoffs or workarounds that the use of Ada may require. A prototype inference engine was built using Ada, and rule firing rates in excess of 500 per second were demonstrated on a single MC68000 processor. The knowledge base uses a directed acyclic graph to represent production lines. The graph allows the use of AND, OR, and NOT logical operators. The inference engine uses a combination of both forward and backward chaining in order to reach goals as quickly as possible. Future efforts will include additional investigation of multiprocessing to improve performance and creating a user interface allowing rule input in an Ada-like syntax. Investigation of multitasking and alternate knowledge base representations will help to analyze some of the performance issues as they relate to larger problems.

  19. ADASAGE, ADA Application Development System

    1 - Description of program or function: ADASAGE is an application development system designed to facilitate rapid and professional construction of applications written in Ada on microcomputers. ADASAGE applications may vary in size from small to large multi-program systems. ADASAGE consists of a collection of re-usable libraries for database management and form and report processing utilities having the following capabilities: basic universal type and function definitions; sequential file input/output; terminal and file input/output; DOS system command execution; data movement and fill; string manipulation; math libraries; bit manipulation; a relational database utility; data validation; menu form and window procedures; report generation; sort/merge, time, and date functions; sound production; editing; and index rebuilding. Each of the capabilities is integrated to allow the development of an efficient system. As an application is designed and developed, the desired ADASAGE capabilities are chosen and included along with any requirements unique to that application. 2 - Method of solution: All ADASAGE applications which use the database, forms (windows, menus, etc.), or reporting functions require a file with a suffix of .DFL. This file contains the database schema, the various forms and windows, and report definitions. The THOR editor is used to create and maintain the .DFL file. This editor operates on a file with the suffix .SRC and creates and edits schemes, forms, and report formats and compile the .SRC file into the .DFL file used by the application. The application will have unique requirements not satisfied by the selected utilities of ADASAGE. The code for these along with the code necessary to import and use the selected ADASAGE utilities constitutes the programmed application. The completed application system will contain the .DFL file produced by the THOR editor, the required ADASAGE utilities, and the programmed application. During the course of normal

  2. AdaNET prototype library administration manual

    Hanley, Lionel

    1989-01-01

    The functions of the AdaNET Prototype Library of Reusable Software Parts is described. Adopted from the Navy Research Laboratory's Reusability Guidebook (V.5.0), this is a working document, customized for use the the AdaNET Project. Within this document, the term part is used to denote the smallest unit controlled by a library and retrievable from it. A part may have several constituents, which may not be individually tracked. Presented are the types of parts which may be stored in the library and the relationships among those parts; a concept of trust indicators which provide measures of confidence that a user of a previously developed part may reasonably apply to a part for a new application; search and retrieval, configuration management, and communications among those who interact with the AdaNET Prototype Library; and the AdaNET Prototype, described from the perspective of its three major users: the part reuser and retriever, the part submitter, and the librarian and/or administrator.

  3. Knowledge, programming, and programming cultures: LISP, C, and Ada

    Rochowiak, Daniel

    1990-01-01

    The results of research 'Ada as an implementation language for knowledge based systems' are presented. The purpose of the research was to compare Ada to other programming languages. The report focuses on the programming languages Ada, C, and Lisp, the programming cultures that surround them, and the programming paradigms they support.

  4. Comparing host and target environments for distributed Ada programs

    Paulk, Mark C.

    1986-01-01

    The Ada programming language provides a means of specifying logical concurrency by using multitasking. Extending the Ada multitasking concurrency mechanism into a physically concurrent distributed environment which imposes its own requirements can lead to incompatibilities. These problems are discussed. Using distributed Ada for a target system may be appropriate, but when using the Ada language in a host environment, a multiprocessing model may be more suitable than retargeting an Ada compiler for the distributed environment. The tradeoffs between multitasking on distributed targets and multiprocessing on distributed hosts are discussed. Comparisons of the multitasking and multiprocessing models indicate different areas of application.

  5. Ada (trademark) projects at NASA. Runtime environment issues and recommendations

    Roy, Daniel M.; Wilke, Randall W.

    1988-01-01

    Ada practitioners should use this document to discuss and establish common short term requirements for Ada runtime environments. The major current Ada runtime environment issues are identified through the analysis of some of the Ada efforts at NASA and other research centers. The runtime environment characteristics of major compilers are compared while alternate runtime implementations are reviewed. Modifications and extensions to the Ada Language Reference Manual to address some of these runtime issues are proposed. Three classes of projects focusing on the most critical runtime features of Ada are recommended, including a range of immediately feasible full scale Ada development projects. Also, a list of runtime features and procurement issues is proposed for consideration by the vendors, contractors and the government.

  6. The OPEN-ADAS Approach to Atomic Data Provision

    Dr O'Mullane of University of Strathclyde presented an overview of the ADAS project (Atomic Data and Analysis Structure, http://www.adas.ac.uk/) and of OPEN-ADAS (http://open.adas.ac.uk/). ADAS is maintained as a self-funding consortium of fusion laboratories. The project provides an interconnected set of computer codes and data collections for modeling the radiating properties of ions and atoms in plasmas. The ADAS data fall into 3 broad classes: 1) Fundamental data such as A- values, cross-sections and effective collision strengths obtained from ADAS collaborators, the literature or data centres. 2) Derived data processed for modeling such as electron temperature and density dependent effective emission coefficients, effective ionization/recombination rates, radiated power and spectral emissivities. 3) Driver data which allow complete regeneration of all ADAS derived data in conjunction with the various ADAS codes. ADAS data uses high quality data as well as baseline data for fall-back when high quality data is not available. The data is mostly embedded in codes and the update without expert help is problematic. The ADAS data formats (adf) are precisely defined and Fortran codes are supplied to read the data sets for easy access. IDL can be used for interactive manipulation. The OPEN-ADAS project is a joint development between the ADAS Project and the IAEA to make the extensive fundamental and derived atomic data for fusion more widely available. It is designed to appeal to both plasma modelers and those interested in the detailed atomic physics. It has been searchable through the Google Scholar and appears in citations, which gives greater visibility and credits to the data producers. The OPEN-ADAS server was replaced due to a series of attacks since June 2011 and was off-line for 8 weeks. The new service removed the registration requirement and hence the user statistics is limited.

  7. Object-oriented programming with mixins in Ada

    Seidewitz, ED

    1992-01-01

    Recently, I wrote a paper discussing the lack of 'true' object-oriented programming language features in Ada 83, why one might desire them in Ada, and how they might be added in Ada 9X. The approach I took in this paper was to build the new object-oriented features of Ada 9X as much as possible on the basic constructs and philosophy of Ada 83. The object-oriented features proposed for Ada 9X, while different in detail, are based on the same kind of approach. Further consideration of this approach led me on a long reflection on the nature of object-oriented programming and its application to Ada. The results of this reflection, presented in this paper, show how a fairly natural object-oriented style can indeed be developed even in Ada 83. The exercise of developing this style is useful for at least three reasons: (1) it provides a useful style for programming object-oriented applications in Ada 83 until new features become available with Ada 9X; (2) it demystifies many of the mechanisms that seem to be 'magic' in most object-oriented programming languages by making them explicit; and (3) it points out areas that are and are not in need of change in Ada 83 to make object-oriented programming more natural in Ada 9X. In the next four sections I will address in turn the issues of object-oriented classes, mixins, self-reference and supertyping. The presentation is through a sequence of examples. This results in some overlap with that paper, but all the examples in the present paper are written entirely in Ada 83. I will return to considerations for Ada 9X in the last section of the paper.

The BNF grammar of an Ada package specification is used as a basis for organization. By organizing the the...

  9. Accommodating Uncertainty in ADAS Models and Data

    The Atomic Data and Analysis Structure (ADAS) is an interconnected set of computer codes and data collections for modelling the radiating properties of ions and atoms in plasmas and for assisting in the analysis and interpretation of spectral measurements. Fundamental atomic data is mediated via collisional-radiative population models to produce the effective coefficients for practical use in impurity transport modelling, influx estimation, beam stopping efficiency and active charge exchange quantification. Away from the coronal picture, the simple connection between fundamental processes and the derived population or emissivity is lost. Instead these coefficients become dependent on many fundamental processes with unknown weightings. The challenge is threefold: to develop methods for assigning an uncertainty to the fundamental data, to propagate these through the population models and to enable techniques to utilize within plasmas models atomic data that comes with an accompanying error surface. Pure atomic properties, such as energy levels and some transition probabilities, are measurable and are known to high precision. However most of the fundamental data required for fusion work, such as excitation and state selective charge transfer cross sections, ionisation and recombination rates (for both electron and ion drivers) remain the result of theoretical calculations and this is not likely to change. The envelope of variation between different methods and calculations is the simplest approach to ascribing an error and is useful in identifying both the principal contributors to the final quantity of interest and to assess its domain of influence. A more refined approach, based on variation of the control parameters of the fundamental ab initio codes, is adopted for this smaller set of significant cross sections. The error for the derived quantities is computed via a statistical sampling methodology assuming an error distribution within the ascribed uncertainty

  10. Ada and its impact on the scientific user

    The Ada programming language is the result of a collective effort to design a common language for programming real-time systems. The design of Ada was initiated by the United States Department of Defense (DoD) in 1975. Ada combines facilities found in most classical languages like Fortran, PL/I, Pascal, and Basic together with many features formerly found only in experimental languages. It is argued that these features make Ada a very decent tool not only for writing real-time programs but also for the development of software in the scientific sector. (orig.)

  13. ADAS: Atomic data, modelling and analysis for fusion

    The Atomic Data and Analysis Structure, ADAS, comprises extensive fundamental and derived atomic data collections, interactive codes for the manipulation and generation of collisional-radiative data and models, off-line codes for large scale fundamental atomic data production and codes for diagnostic analysis in the fusion and astrophysical environments. ADAS data are organized according to precise specifications, tuned to application and are assigned to numbered ADAS data formats. Some of these formats contain very large quantities of data and some have achieved wide-scale adoption in the fusion community.The paper focuses on recent extensions of ADAS designed to orient ADAS to the needs of ITER. The issue of heavy atomic species, expected to be present as ITER wall and divertor materials, dopants or control species, will be addressed with a view to the economized handling of the emission and ionisation state data needed for diagnostic spectral analysis. Charge exchange and beam emission spectroscopic capabilities and developments in ADAS will be reviewed from an ITER perspective and in the context of a shared analysis between fusion laboratories. Finally an overview and summary of current large scale fundamental data production in the framework of the ADAS project will be given and its intended availability in both fusion and astrophysics noted

    Full Text Available Bleaching of teeth for cosmetic reasons is a popular aspect of cosmetic dentistry because patients realize the aesthetical benefits of these products. The dentist as a clinician's practitioner must be knowledgeable of the products and their application techniques. Bleaching materials which are safe and effective are the ADA accepted or manufactured by those which have already haved ISO certificate. Dentist must have enough knowledge about in-office bleaching prescribed for home-use bleaching including their contra indication and side effects, to advise the patients and provide effective bleaching services.

  16. A report on NASA software engineering and Ada training requirements

    Legrand, Sue; Freedman, Glenn B.; Svabek, L.

    1987-01-01

    NASA's software engineering and Ada skill base are assessed and information that may result in new models for software engineering, Ada training plans, and curricula are provided. A quantitative assessment which reflects the requirements for software engineering and Ada training across NASA is provided. A recommended implementation plan including a suggested curriculum with associated duration per course and suggested means of delivery is also provided. The distinction between education and training is made. Although it was directed to focus on NASA's need for the latter, the key relationships to software engineering education are also identified. A rationale and strategy for implementing a life cycle education and training program are detailed in support of improved software engineering practices and the transition to Ada.

    Full Text Available Cada vez cobra más fuerza la clasificación de las drogas que las divide en psictrópicos y estupefacientes y en Costa Rica se ha añadido la sustancia inhalable. Se hace una ligera definición sobre lo que es una droga y la diferencia con las sustancias indispensables para el organismo como son el agua, el oxígeno y los alimentos las cuales son necesarias para el mismo. En el mundo cada vez es mayor el número de estas sustancias fiscalizadas, y que es considerada una acción delictiva en determinadas ocasiones. Convenios internacionales que deben ser ratificados por las naciones exige que se especifique previamente el objeto material del Delito. Las Drogas Diseñadas son aquellas que por algún cambio realizado en un laboratorio sobre su molécula, tienen los efectos muchas veces superiores a la droga madre, pero que por no estar en la lista de drogas fiscalizadas en el momento de aparición de la misma, va permitiendo que, mientras se agrega a la lista de las mencionadas drogas fiscalizadas, estos actos queden impunes con gran daño por la Salud Pública y del individuo durante mucho tiempo. Costa Rica no escapa de esta realidad por lo que el "narcotraficante" siempre irá adelante con nuevas drogas diseñadas causando grandes estragos, mientras las mismas poco a poco se van incluyendo en la lista de sustancias fiscalizadas.

  18. GRASP/Ada: Graphical Representations of Algorithms, Structures, and Processes for Ada. The development of a program analysis environment for Ada: Reverse engineering tools for Ada, task 2, phase 3

    Cross, James H., II

    1991-01-01

    The main objective is the investigation, formulation, and generation of graphical representations of algorithms, structures, and processes for Ada (GRASP/Ada). The presented task, in which various graphical representations that can be extracted or generated from source code are described and categorized, is focused on reverse engineering. The following subject areas are covered: the system model; control structure diagram generator; object oriented design diagram generator; user interface; and the GRASP library.

  19. Hydraulic Capacity of an ADA Compliant Street Drain Grate

    Lottes, Steven A. [Argonne National Lab. (ANL), Argonne, IL (United States); Bojanowski, Cezary [Argonne National Lab. (ANL), Argonne, IL (United States)

    2015-09-01

    Resurfacing of urban roads with concurrent repairs and replacement of sections of curb and sidewalk may require pedestrian ramps that are compliant with the American Disabilities Act (ADA), and when street drains are in close proximity to the walkway, ADA compliant street grates may also be required. The Minnesota Department of Transportation ADA Operations Unit identified a foundry with an available grate that meets ADA requirements. Argonne National Laboratory’s Transportation Research and Analysis Computing Center used full scale three dimensional computational fluid dynamics to determine the performance of the ADA compliant grate and compared it to that of a standard vane grate. Analysis of a parametric set of cases was carried out, including variation in longitudinal, gutter, and cross street slopes and the water spread from the curb. The performance of the grates was characterized by the fraction of the total volume flow approaching the grate from the upstream that was captured by the grate and diverted into the catch basin. The fraction of the total flow entering over the grate from the side and the fraction of flow directly over a grate diverted into the catch basin were also quantities of interest that aid in understanding the differences in performance of the grates. The ADA compliant grate performance lagged that of the vane grate, increasingly so as upstream Reynolds number increased. The major factor leading to the performance difference between the two grates was the fraction of flow directly over the grates that is captured by the grates.

  20. Examining the reliability of ADAS-Cog change scores.

    Grochowalski, Joseph H; Liu, Ying; Siedlecki, Karen L

    2016-09-01

    The purpose of this study was to estimate and examine ways to improve the reliability of change scores on the Alzheimer's Disease Assessment Scale, Cognitive Subtest (ADAS-Cog). The sample, provided by the Alzheimer's Disease Neuroimaging Initiative, included individuals with Alzheimer's disease (AD) (n = 153) and individuals with mild cognitive impairment (MCI) (n = 352). All participants were administered the ADAS-Cog at baseline and 1 year, and change scores were calculated as the difference in scores over the 1-year period. Three types of change score reliabilities were estimated using multivariate generalizability. Two methods to increase change score reliability were evaluated: reweighting the subtests of the scale and adding more subtests. Reliability of ADAS-Cog change scores over 1 year was low for both the AD sample (ranging from .53 to .64) and the MCI sample (.39 to .61). Reweighting the change scores from the AD sample improved reliability (.68 to .76), but lengthening provided no useful improvement for either sample. The MCI change scores had low reliability, even with reweighting and adding additional subtests. The ADAS-Cog scores had low reliability for measuring change. Researchers using the ADAS-Cog should estimate and report reliability for their use of the change scores. The ADAS-Cog change scores are not recommended for assessment of meaningful clinical change.

  1. Remolding Diversified Objects in Ada95: Toward A-Object Pattern

    2001-01-01

    Ada provides full capacities of supporting object-orientation,but the diversified objects patterned in Ada are so intricate that Ada95's aim would be demolished. In order to complement the disfigurement that Ada does lack for a pr istine notion of class, this paper presents a remolded object pattern known as A -object, an Ada-based class description language A-ObjAda aiming at support f or A-object pattern and the related approach for key algorithms and implementation . In consequent, A-ObjAda hereby promotes Ada with highlighted object-orientati on , which not only effectively exploits the capacities in Ada95, but also rational ly hides befuddling concepts from Ada95.

    Cordycepin, which is an analogue of a nucleoside adenosine, exhibits a wide variety of pharmacological activities including anticancer effects. In this study, ADA1- and ADA2-expressing HEK293 cells were established to determine the major ADA isoform responsible for the deamination of cordycepin. While the metabolic rate of cordycepin deamination was similar between ADA2-expressing and Mock cells, extensive metabolism of cordycepin was observed in the ADA1-expressing cells with K m and V max v...

  3. ADA plaintiff must show AIDS limits major life activities.

    1998-05-15

    In a rare case, a Federal court ruled that AIDS does not automatically qualify a plaintiff for legal protection under the Americans with Disabilities Act (ADA). [Name removed], an Illinois Wal-Mart stock clerk, was fired weeks after telling the store's general manager of his HIV status. [Name removed] alleges that the firing was due solely to his disease. Wal-Mart contends that [name removed] was fired for sexually harassing a co-worker, and says that since [name removed] was asymptomatic and asked for no accommodations, he does not qualify for ADA protection. Magistrate Morton Denlow agreed, saying that [name removed] raised no genuine issues about whether the ADA should protect him. A trial is scheduled for May. PMID:11365337

  4. An automated quality assessor for Ada object-oriented designs

    Bailin, Sidney C.

    1988-01-01

    A tool for evaluating object-oriented designs (OODs) for Ada software is described. The tool assumes a design expressed as a hierarchy of object diagrams. A design of this type identifies the objects of a system, an interface to each object, and the usage relationships between objects. When such a design is implemented in Ada, objects become packages, interfaces become package specifications, and usage relationships become Ada `with' clauses and package references. An automated quality assessor has been developed that is based on flagging undesirable design constructs. For convenience, distinctions are made among three levels of severity: questionable, undesirable, and hazardous. A questionable construct is one that may well be appropriate. An undesirable construct is one that should be changed because it is potentially harmful to the reliability, maintainability, or reusability of the software. A hazardous construct is one that is undesirable and that introduces a high level of risk.

    1990-01-01

    The study, formulation, and generation of structures for Ada (GRASP/Ada) are discussed in this second phase report of a three phase effort. Various graphical representations that can be extracted or generated from source code are described and categorized with focus on reverse engineering. The overall goal is to provide the foundation for a CASE (computer-aided software design) environment in which reverse engineering and forward engineering (development) are tightly coupled. Emphasis is on a subset of architectural diagrams that can be generated automatically from source code with the control structure diagram (CSD) included for completeness.

  7. Techniques and implementation of the embedded rule-based expert system using Ada

    Liberman, Eugene M.; Jones, Robert E.

    1991-01-01

    Ada is becoming an increasingly popular programming language for large Government-funded software projects. Ada with its portability, transportability, and maintainability lends itself well to today's complex programming environment. In addition, expert systems have also assured a growing role in providing human-like reasoning capability and expertise for computer systems. The integration of expert system technology with Ada programming language, specifically a rule-based expert system using an ART-Ada (Automated Reasoning Tool for Ada) system shell is discussed. The NASA Lewis Research Center was chosen as a beta test site for ART-Ada. The test was conducted by implementing the existing Autonomous Power EXpert System (APEX), a Lisp-base power expert system, in ART-Ada. Three components, the rule-based expert system, a graphics user interface, and communications software make up SMART-Ada (Systems fault Management with ART-Ada). The main objective, to conduct a beta test on the ART-Ada rule-based expert system shell, was achieved. The system is operational. New Ada tools will assist in future successful projects. ART-Ada is one such tool and is a viable alternative to the straight Ada code when an application requires a rule-based or knowledge-based approach.

  8. Supreme Court to hear ADA suit involving arbitration clause.

    1998-03-20

    The U.S. Supreme Court agreed to review a third case under the Americans with Disabilities Act (ADA) this year. The Supreme Court previously agreed to hear [name removed] v. [Name removed], involving a dentist who refused to treat an HIV-positive patient in his office. The second case is Pennsylvania Department of Corrections v. [Name removed], in which the State asserts that the ADA does not apply to prisons. The third involves whether an arbitration clause in a labor union's collective bargaining agreement prevents a court from hearing a union member's discrimination claim. [Name removed] longshoreman [name removed] alleges that the [name removed] and several employers violated the ADA when they refused to help him for employment referral. [Name removed] previously settled a workers' compensation disability claim with [name removed] and Terminal Co., his employer. Three years later he applied for work at the International Longshoreman's Association hiring hall and was referred to four different employers. The employers discovered he had received a worker's compensation settlement and would no longer accept [name removed] for employment referral. The case is important because union members can continue to file ADA charges with the EEOC and the outcomes will vary depending on the circuit where the union member happens to file the claim.

  12. Plaintiff cannot sue under ADA if he seeks disability benefits.

    1996-08-23

    [Name removed] sued a New Jersey Disney store for AIDS discrimination under the Americans with Disabilities Act (ADA). At the same time, [name removed] applied for disability benefits. A U.S. Circuit Court of Appeals ruled that a plaintiff who applies for disability benefits is no longer a qualified individual with a disability and therefore cannot sue for employment discrimination under the Americans with Disabilities Act (ADA). Disney fired [name removed] on November 18, 1993, after he took $2 from the cash register to buy cigarettes. Confronted with the accusation, [name removed] told his supervisor he had AIDS. He was fired immediately. Although [name removed] alleged Disney used the $2 cash transaction as a pretext to fire him, a Federal judge said [name removed] was barred from suing because of the inconsistency between his statements on the disability applications and on the lawsuit.

  13. AdaBoost for Improved Voice-Band Signal Classification

    2007-01-01

    A good voice-band signal classification can not only enable the safe application of speech coding techniques,the implementation of a Digital Signal Interpolation (DSI)system, but also facilitate network administration and planning by providing accurate voice-band traffic analysis.A new method is proposed to detect and classify the presence of various voice-band signals on the General Switched Telephone Network ( GSTN ). The method uses a combination of simple base classifiers through the AdaBoost algorithm. The conventional classification features for voiceband data classification are combined and optimized by the AdaBoost algorithm and spectral subtraction method.Experiments show the simpleness, effectiveness, efficiency and flexibility of the method.

  15. Bernoulli Numbers: from Ada Lovelace to the Debye Functions

    Sparavigna, Amelia Carolina

    2016-01-01

    Jacob Bernoulli owes his fame for the numerous contributions to calculus and for his discoveries in the field of probability. Here we will discuss one of his contributions to the theory of numbers, the Bernoulli numbers. They were proposed as a case study by Ada Lovelace in her analysis of Menabrea's report on Babbage Analytical Engine. It is probable that it was this Lovelace's work, that inspired Hans Thirring in using the Bernoulli numbers in the calculus of the Debye functions.

  16. AN ADA LINEAR ALGEBRA PACKAGE MODELED AFTER HAL/S

    Klumpp, A. R.

    1994-01-01

    This package extends the Ada programming language to include linear algebra capabilities similar to those of the HAL/S programming language. The package is designed for avionics applications such as Space Station flight software. In addition to the HAL/S built-in functions, the package incorporates the quaternion functions used in the Shuttle and Galileo projects, and routines from LINPAK that solve systems of equations involving general square matrices. Language conventions in this package follow those of HAL/S to the maximum extent practical and minimize the effort required for writing new avionics software and translating existent software into Ada. Valid numeric types in this package include scalar, vector, matrix, and quaternion declarations. (Quaternions are fourcomponent vectors used in representing motion between two coordinate frames). Single precision and double precision floating point arithmetic is available in addition to the standard double precision integer manipulation. Infix operators are used instead of function calls to define dot products, cross products, quaternion products, and mixed scalar-vector, scalar-matrix, and vector-matrix products. The package contains two generic programs: one for floating point, and one for integer. The actual component type is passed as a formal parameter to the generic linear algebra package. The procedures for solving systems of linear equations defined by general matrices include GEFA, GECO, GESL, and GIDI. The HAL/S functions include ABVAL, UNIT, TRACE, DET, INVERSE, TRANSPOSE, GET, PUT, FETCH, PLACE, and IDENTITY. This package is written in Ada (Version 1.2) for batch execution and is machine independent. The linear algebra software depends on nothing outside the Ada language except for a call to a square root function for floating point scalars (such as SQRT in the DEC VAX MATHLIB library). This program was developed in 1989, and is a copyrighted work with all copyright vested in NASA.

  17. Software tools to aid Pascal and Ada program design

    Jankowitz, H.T.

    1987-01-01

    This thesis describes a software tool which analyses the style and structure of Pascal and Ada programs by ensuring that some minimum design requirements are fulfilled. The tool is used in much the same way as a compiler is used to teach students the syntax of a language, only in this case issues related to the design and structure of the program are of paramount importance. The tool operates by analyzing the design and structure of a syntactically correct program, automatically generating a report detailing changes that need to be made in order to ensure that the program is structurally sound. The author discusses how the model gradually evolved from a plagiarism detection system which extracted several measurable characteristics in a program to a model that analyzed the style of Pascal programs. In order to incorporate more-sophistical concepts like data abstraction, information hiding and data protection, this model was then extended to analyze the composition of Ada programs. The Ada model takes full advantage of facilities offered in the language and by using this tool the standard and quality of written programs is raised whilst the fundamental principles of program design are grasped through a process of self-tuition.

  18. Monogenic polyarteritis: the lesson of ADA2 deficiency.

    Caorsi, Roberta; Penco, Federica; Schena, Francesca; Gattorno, Marco

    2016-01-01

    The deficiency of Adenosine Deaminase 2 (DADA2) is a new autoinflammatory disease characterised by an early onset vasculopathy with livedoid skin rash associated with systemic manifestations, CNS involvement and mild immunodeficiency.This condition is secondary to autosomal recessive mutations of CECR1 (Cat Eye Syndrome Chromosome Region 1) gene, mapped to chromosome 22q11.1, that encodes for the enzymatic protein adenosine deaminase 2 (ADA2). By now 19 different mutations in CECR1 gene have been detected.The pathogenetic mechanism of DADA2 is still unclear. ADA2 in a secreted protein mainly expressed by cells of the myeloid lineage; its enzymatic activity is higher in conditions of hypoxia, inflammation and oncogenesis. Moreover ADA2 is able to induce macrophages proliferation and differentiation; it's deficiency is in fact associated with a reduction of anti-inflammatory macrophages (M2). The deficiency of ADA2 is also associated with an up-regulation of neutrophils-expressed genes and an increased secretion of pro-inflammatory cytokines. The mild immunodeficiency detected in many DADA2 patients suggests a role of this protein in the adaptive immune response; an increased mortality of B cells and a reduction in the number of memory B cells, terminally differentiated B cells and plasmacells has been described in many patients. The lack of the protein is associated with endothelium damage; however the function of this protein in the endothelial homeostasis is still unknown.From the clinical point of view, this disease is characterized by a wide spectrum of severity. Chronic or recurrent systemic inflammation with fever, elevation of acute phase reactants and skin manifestations (mainly represented by livedo reticularis) is the typical clinical picture. While in some patients the disease is mild and skin-limited, others present a severe, even lethal, disease with multi-organ involvement; the CNS involvement is rather common with ischemic or hemorrhagic strokes.

  4. Efficient Ada multitasking on a RISC register window architecture

    Kearns, J. P.; Quammen, D.

    1987-01-01

    This work addresses the problem of reducing context switch overhead on a processor which supports a large register file - a register file much like that which is part of the Berkeley RISC processors and several other emerging architectures (which are not necessarily reduced instruction set machines in the purest sense). Such a reduction in overhead is particularly desirable in a real-time embedded application, in which task-to-task context switch overhead may result in failure to meet crucial deadlines. A storage management technique by which a context switch may be implemented as cheaply as a procedure call is presented. The essence of this technique is the avoidance of the save/restore of registers on the context switch. This is achieved through analysis of the static source text of an Ada tasking program. Information gained during that analysis directs the optimized storage management strategy for that program at run time. A formal verification of the technique in terms of an operational control model and an evaluation of the technique's performance via simulations driven by synthetic Ada program traces are presented.

  5. Rationale for the proposed standard for a generic package of primitive functions for Ada

    Dritz, K.W.

    1990-12-01

    This paper supplements the Proposed Standard for a Generic Package of Primitive Functions for Ada,'' written by the ISO- IEC/JTC1/SC22/WG9 (Ada) Numerics Rapporteur Group. Based on recommendations made jointly by the ACM SIGAda Numerics Working Group and the Ada-Europe Numerics Working Group, the proposed primitive functions standard is the second of several anticipated secondary standards to address the interrelated issues of portability, efficiency, and robustness of numerical software written in Ada. Its purpose, features, and developmental history are outlined in this commentary. 16 refs.

  6. The Impact of Ada and Object-Oriented Design in NASA Goddard's Flight Dynamics Division

    Waligora, Sharon; Bailey, John; Stark, Mike

    1996-01-01

    This paper presents the highlights and key findings of 10 years of use and study of Ada and object-oriented design in NASA Goddard's Flight Dynamics Division (FDD). In 1985, the Software Engineering Laboratory (SEL) began investigating how the Ada language might apply to FDD software development projects. Although they began cautiously using Ada on only a few pilot projects, they expected that, if the Ada pilots showed promising results, the FDD would fully transition its entire development organization from FORTRAN to Ada within 10 years. However, 10 years later, the FDD still produced 80 percent of its software in FORTRAN and had begun using C and C++, despite positive results on Ada projects. This paper presents the final results of a SEL study to quantify the impact of Ada in the FDD, to determine why Ada has not flourished, and to recommend future directions regarding Ada. Project trends in both languages are examined as are external factors and cultural issues that affected the infusion of this technology. The detailed results of this study were published in a formal study report in March of 1995. This paper supersedes the preliminary results of this study that were presented at the Eighteenth Annual Software Engineering Workshop in 1993.

  7. Autoimmune dysregulation and purine metabolism in adenosine deaminase (ADA-deficiency

    Aisha Vanessa Sauer

    2012-08-01

    Full Text Available Genetic defects in the adenosine deaminase (ADA gene are among the most common causes for severe combined immunodeficiency (SCID. ADA-SCID patients suffer from lymphopenia, severely impaired cellular and humoral immunity, failure to thrive and recurrent infections. Currently available therapeutic options for this otherwise fatal disorder include bone marrow transplantation (BMT, enzyme replacement therapy with bovine ADA (PEG-ADA or hematopoietic stem cell gene therapy (HSC-GT. Although varying degrees of immune reconstitution can be achieved by these treatments, breakdown of tolerance is a major concern in ADA-SCID. Immune dysregulation such as autoimmune hypothyroidism, diabetes mellitus, hemolytic anemia, and immune thrombocytopenia are frequently observed in milder forms of the disease. However, several reports document similar complications also in patients on long-term PEG-ADA and after BMT or GT treatment.A skewed repertoire and decreased immune functions have been implicated in autoimmunity observed in certain B-cell and/or T-cell immunodeficiencies, but it remains unclear to what extent specific mechanisms of tolerance are affected in ADA deficiency. Herein we provide an overview about ADA-SCID and the autoimmune manifestations reported in these patients before and after treatment. We also assess the value of the ADA-deficient mouse model as a useful tool to study both immune and metabolic disease mechanisms. With focus on regulatory T and B cells we discuss the lymphocyte subpopulations particularly prone to contribute to the loss of self-tolerance and onset of autoimmunity in ADA deficiency. Moreover we address which aspects of immune dysregulation are specifically related to alterations in purine metabolism caused by the lack of ADA and the subsequent accumulation of metabolites with immunomodulatory properties.

  8. Inclusion of geriatric nutrition in ADA-approved undergraduate programs.

    Shoaf, L R; Jensen, H M

    1989-09-01

    All ADA Plan IV programs were surveyed to determine whether geriatric nutrition was included in their curriculums. Of the 268 Plan IV programs, 66% responded. Less than one-fifth of the programs offered or planned to offer a specific geriatric nutrition course. An overview of geriatric nutrition occurred most frequently in a human nutrition course. A practicum/clinical experience or a course other than nutrition most frequently provided in-depth study, if such was available. Nursing homes and congregate meal sites were the primary locations for experiences with the geriatric population. Major activities with that age group included (a) taking diet histories, (b) making nutrition assessments, and (c) providing diet instruction. In some programs, didactic and experiential training with the geriatric population may not be adequate to prepare dietetic undergraduate students to meet the health care needs of that growing segment of society.

  9. Large distributed control system using Ada in fusion research

    Van Arsdall, P J; Woodruff, J P

    1998-08-11

    Construction of the National Ignition Facility laser at Lawrence Livermore National Laboratory features a distributed control system that uses object-oriented software engineering techniques. Control of 60,000 devices is effected using a network of some 500 computers. The software is being written in Ada and communicates through CORBA. Software controls are implemented in two layers: individual device controllers and a supervisory layer. The software architecture provides services in the form of frameworks that address issues common to event-driven control systems. Those services are allocated to levels that strictly prescribe their interdependency so the levels are separately reusable. The project has completed its final design review. The delivery of the first increment takes place in October 1998. Keywords Distributed control system, object-oriented development, CORBA, application frameworks, levels of abstraction

  13. The implementation and use of Ada on distributed systems with reliability requirements

    Reynolds, P. F.; Knight, J. C.; Urquhart, J. I. A.

    1983-01-01

    The issues involved in the use of the programming language Ada on distributed systems are discussed. The effects of Ada programs on hardware failures such as loss of a processor are emphasized. It is shown that many Ada language elements are not well suited to this environment. Processor failure can easily lead to difficulties on those processors which remain. As an example, the calling task in a rendezvous may be suspended forever if the processor executing the serving task fails. A mechanism for detecting failure is proposed and changes to the Ada run time support system are suggested which avoid most of the difficulties. Ada program structures are defined which allow programs to reconfigure and continue to provide service following processor failure.

  14. Storage management in Ada. Three reports. Volume 1: Storage management in Ada as a risk to the development of reliable software. Volume 2: Relevant aspects of language. Volume 3: Requirements of the language versus manifestations of current implementations

    Auty, David

    1988-01-01

    The risk to the development of program reliability is derived from the use of a new language and from the potential use of new storage management techniques. With Ada and associated support software, there is a lack of established guidelines and procedures, drawn from experience and common usage, which assume reliable behavior. The risk is identified and clarified. In order to provide a framework for future consideration of dynamic storage management on Ada, a description of the relevant aspects of the language is presented in two sections: Program data sources, and declaration and allocation in Ada. Storage-management characteristics of the Ada language and storage-management characteristics of Ada implementations are differentiated. Terms that are used are defined in a narrow and precise sense. The storage-management implications of the Ada language are described. The storage-management options available to the Ada implementor and the implications of the implementor's choice for the Ada programmer are also described.

    This paper describes the work in progress to select the Ada compilers for the Space Station Freedom Program (SSFP) Software Support Environment (SSE) project. The purpose of the SSE Ada compiler evaluation team is to establish the criteria, test suites, and benchmarks to be used for evaluating Ada compilers for the mainframes, workstations, and the realtime target for flight- and ground-based computers. The combined efforts and cooperation of the customer, subcontractors, vendors, academia and SIGAda groups made it possible to acquire the necessary background information, benchmarks, test suites, and criteria used.

  1. The implementation and use of Ada on distributed systems with high reliability requirements

    Knight, J. C.

    1987-01-01

    Performance analysis was begin on the Ada implementations. The goal is to supply the system designer with tools that will allow a rational decision to be made about whether a particular implementation can support a given application early in the design cycle. Primary activities were: analysis of the original approach to recovery in distributed Ada programs using the Advanced Transport Operating System (ATOPS) example; review and assessment of the original approach which was found to be capable of improvement; preparation and presentation of a paper at the 1987 Washington DC Ada Symposium; development of a refined approach to recovery that is presently being applied to the ATOPS example; and design and development of a performance assessment scheme for Ada programs based on a flexible user-driven benchmarking system.

  3. The implications of the ADA Amendments Act of 2008 for residency training program administration.

    Regenbogen, Alexandra; Recupero, Patricia R

    2012-01-01

    The Americans with Disabilities Act (ADA) is rarely invoked by medical residents in training. Dr. Martin Jakubowski, a family medicine resident with Asperger's disorder, was dismissed for communicating poorly with patients, peers, and supervisors and for issuing dangerous medical orders. In an attempt to become reinstated, he sued under the ADA (Jakubowski v. The Christ Hospital), arguing that the program had failed to make reasonable accommodation for his disability. The Sixth Circuit Court of Appeals ruled in favor of the hospital, finding that although the doctor was disabled under the ADA, he had failed to demonstrate that he was otherwise qualified for the position. This article comments on the ADA Amendments Act of 2008, the Equal Employment Opportunity Commission (EEOC) guidelines from 2011 and their application to medical residency training, and the Accreditation Council for Graduate Medical Education (ACGME) core competencies as essential job functions.

  8. Constructing a working taxonomy of functional Ada software components for real-time embedded system applications

    Wallace, Robert

    1986-01-01

    A major impediment to a systematic attack on Ada software reusability is the lack of an effective taxonomy for software component functions. The scope of all possible applications of Ada software is considered too great to allow the practical development of a working taxonomy. Instead, for the purposes herein, the scope of Ada software application is limited to device and subsystem control in real-time embedded systems. A functional approach is taken in constructing the taxonomy tree for identified Ada domain. The use of modular software functions as a starting point fits well with the object oriented programming philosophy of Ada. Examples of the types of functions represented within the working taxonomy are real time kernels, interrupt service routines, synchronization and message passing, data conversion, digital filtering and signal conditioning, and device control. The constructed taxonomy is proposed as a framework from which a need analysis can be performed to reveal voids in current Ada real-time embedded programming efforts for Space Station.

  9. An Ada-based preprocessor language for concurrent object oriented programming

    In this paper, implementation issues of concurrent-objected programming using Ada 95 are addressed. Ada is not a pure object-oriented language; in order to make it so, a uniform template for structuring object classes is proposed. The template constitutes a basis for an Ada-based preprocessor language that handles concurrent object-oriented programming. The preprocessor accepts Ada-like object-oriented programs (object classes, subclasses and main program) as input and produces Ada 95 concurrent object-oriented program units as output. The preprocessor language has the advantage of adding a new component to the class specification called the protocol, which specifies the order for requesting methods f an object. The preprocessor also touches on the extensibility of object classes issue. It supports defining class hierarchies by inheritance and aggregation. In addition, the preprocessor language supports the re-use of Ada packages, which are not necessarily written according to the object-oriented approach. The paper also investigates the definition of circular dependent object classes and proposes a solution for introducing a collection of classes. (author)

  10. Vector-matrix-quaternion, array and arithmetic packages: All HAL/S functions implemented in Ada

    Klumpp, Allan R.; Kwong, David D.

    1986-01-01

    The HAL/S avionics programmers have enjoyed a variety of tools built into a language tailored to their special requirements. Ada is designed for a broader group of applications. Rather than providing built-in tools, Ada provides the elements with which users can build their own. Standard avionic packages remain to be developed. These must enable programmers to code in Ada as they have coded in HAL/S. The packages under development at JPL will provide all of the vector-matrix, array, and arithmetic functions described in the HAL/S manuals. In addition, the linear algebra package will provide all of the quaternion functions used in Shuttle steering and Galileo attitude control. Furthermore, using Ada's extensibility, many quaternion functions are being implemented as infix operations; equivalent capabilities were never implemented in HAL/S because doing so would entail modifying the compiler and expanding the language. With these packages, many HAL/S expressions will compile and execute in Ada, unchanged. Others can be converted simply by replacing the implicit HAL/S multiply operator with the Ada *. Errors will be trapped and identified. Input/output will be convenient and readable.

  11. 基于Online AdaBoost的偏振图像目标跟踪%Polarization image object tracking based on Online AdaBoost

    2011-01-01

    根据偏振图像的特点,文章提出一种基于在线AdaBoost的目标跟踪方法.该方法以最小二乘回归作为弱分类器,以强度、偏振度和边缘方向特征组成的向量为其输入;通过AdaBoost算法将多个弱分类器集成为强分类器,并在跟踪过程中利用AdaBoost算法对强分类器进行在线更新,以适应目标与背景的变化;利用强分类器生成当前置信图,在置信图上利用粒子滤波估计目标的状态.实验结果表明,该方法能够在复杂背景下稳定地跟踪目标.%A polarization image object tracking method is proposed based on Online Adaboost. The least square regression is used as the weak classifier, with feature vectors of intensity, polarization degree and margin direction chosen for the input. The ensemble of weak classifiers is integrated into a strong classifier by AdaBoost algorithm, and this strong classifier is updated online by AdaBoost algorithm during tracking in order to adapt to the change of the object or the background. Current confidence map is given by using the strong classifier, and based on this map the new state of the object is estimated by using particle filter. Experimental results show that the proposed method is robust and efficient in polarization image object tracking on complex background.

  12. Platelet aggregation and serum adenosine deaminase (ADA) activity in pregnancy associated with diabetes, hypertension and HIV.

    Leal, Claudio A M; Leal, Daniela B R; Adefegha, Stephen A; Morsch, Vera M; da Silva, José E P; Rezer, João F P; Schrekker, Clarissa M L; Abdalla, Faida H; Schetinger, Maria R C

    2016-07-01

    Platelet aggregation and adenosine deaminase (ADA) activity were evaluated in pregnant women living with some disease conditions including hypertension, diabetes mellitus and human immunodeficiency virus infection. The subject population is consisted of 15 non-pregnant healthy women [control group (CG)], 15 women with normal pregnancy (NP), 7 women with hypertensive pregnancy (HP), 10 women with gestational diabetes mellitus (GDM) and 12 women with human immunodeficiency virus-infected pregnancy (HIP) groups. The aggregation of platelets was checked using an optical aggregometer, and serum ADA activity was determined using the colorimetric method. After the addition of 5 µM of agonist adenosine diphosphate, the percentage of platelet aggregation was significantly (p pregnancy and pregnancy-associated diseases suggest that platelet aggregation and ADA activity could serve as peripheral markers for the development of effective therapy in the maintenance of homeostasis and some inflammatory process in these pathophysiological conditions.

  13. A New Method of Cloud Detection Based on Cascaded AdaBoost

    Cloud detection of remote sensing image is a critical step in the processing of the remote sensing images. How to quickly, accurately and effectively detect cloud on remote sensing images, is still a challenging issue in this area. In order to avoid disadvantages of the current algorithms, the cascaded AdaBoost classifier algorithm is successfully applied to the cloud detection. A new algorithm combined cascaded AdaBoost classifier and multi-features, is proposed in this paper. First, multi-features based on the color, texture and spectral features are extracted from the remote sensing image. Second, the automatic cloud detection model is obtained based on the cascaded AdaBoost algorithm. In this paper, the results show that the new algorithm can determine cloud detection model and threshold values adaptively for different resolution remote sensing training data. The accuracy of cloud detection is improved. So it is a new effective algorithm for the cloud detection of remote sensing images

  14. An enhanced Ada run-time system for real-time embedded processors

    Sims, J. T.

    1991-01-01

    An enhanced Ada run-time system has been developed to support real-time embedded processor applications. The primary focus of this development effort has been on the tasking system and the memory management facilities of the run-time system. The tasking system has been extended to support efficient and precise periodic task execution as required for control applications. Event-driven task execution providing a means of task-asynchronous control and communication among Ada tasks is supported in this system. Inter-task control is even provided among tasks distributed on separate physical processors. The memory management system has been enhanced to provide object allocation and protected access support for memory shared between disjoint processors, each of which is executing a distinct Ada program.

    1985-01-01

    The E. coli ada+ gene product that controls the adaptive response to alkylating agents has been purified to apparent homogeneity using an overproducing expression vector system. This 39 kDa protein repairs 0(6)-methylguanine and 0(4)-methylthymine residues in alkylated DNA by transfer of the methyl group from the base to a cysteine residue in the protein itself. The Ada protein also corrects one of the stereoisomers of methyl phosphotriesters in DNA by the same mechanism, while the other isom...

  18. ADA, the Programming Language of Choice for the UPMSat-2 Satellite

    Garrido, Jorge; Zamorano, Juan; de la Puente, Juan A.; Alonso, Alejandro; Salazar, Emilio

    2015-09-01

    The proper selection of development mechanisms and tools is essential for the final success of any engineering project. This is also true when it comes to software development. Furthermore, when the system shows very specific and hard to meet requirements, as it happens for high-integrity real-time systems, the appropriate selection is crucial. For this kind of systems, Ada has proven to be a successful companion, and satellites are not an exception. The paper presents the reasons behind the selection of Ada for the UPMSat-2 development, along with the experience and examples on its usage.

  19. The Spectrum Sensing Algorithm Based AdaBoost in Cognitive Radio

    Tian, Deyong; Wang, Xin

    To solve the low detection rate of the primary user in the cognitive radio environment, we propose a spectrum sensing method based on AdaBoost in the case of low SNR. In this paper, a set of received signal spectrum features are first calculated and extracted the discriminant feature vector as training samples and testing samples for classification. Finally, we utilize the trained AdaBoost to detect the primary user. Test result shows that the proposed algorithm is not affected by uncertainty factors of noise and has high performance to classification detection compared with ANN, SVM and maximum-minimum eigenvalue (MME).

  7. Introducing New AdaBoost Features for Real-Time Vehicle Detection

    Stanciulescu, Bogdan; Moutarde, Fabien

    2009-01-01

    This paper shows how to improve the real-time object detection in complex robotics applications, by exploring new visual features as AdaBoost weak classifiers. These new features are symmetric Haar filters (enforcing global horizontal and vertical symmetry) and N-connexity control points. Experimental evaluation on a car database show that the latter appear to provide the best results for the vehicle-detection problem.

    The objective of this paper is to: describe the phenotype compound heterozygote for mutations in CECR1 in two children. We describe the clinical and immunological phenotype, including the assessment of ADA2 activity, cytokine expression, interferon-stimulated and neutrophil-stimulated gene signatures, and the results of CECR1 sequencing. The first patient presented with intermittent fever, cutaneous vasculitis, myalgia and muscle inflammation on MRI leading to a provisional diagnosis of periarteritis nodosa. Subsequently, two cerebral lacunar lesions were identified following a brain stroke. Clinical features improved on anti-tumour necrosis factor therapy. The first patient's sister demonstrated early-onset, long-lasting anaemia with mild biological inflammation; at the ages of 3 and 5 years, she had presented 2 acute, transient neurological events with lacunar lesions on MRI. CECR1 sequencing identified both sisters to be compound heterozygous for a p.Tyr453Cys mutation and a previously undescribed deletion of exon 7. ADA2 activity was reduced by 50%. Neutrophil-stimulated genes were not overexpressed, but interferon-stimulated genes were. The expression of a panel of other cytokine transcripts was not significantly altered. In conclusion, searching for CECR1 mutation or assessing ADA2 activity should be considered in patients with an atypical presentation of inflammatory disease. PMID:27252897

  9. Ada (R) assessment: An important issue within European Columbus Support Technology Programme

    Vielcanet, P.

    1986-01-01

    Software will be more important and more critical for Columbus than for any ESA previous project. As a simple comparison, overall software size has been in the range of 100 K source statements for EXOSAT, 500 K for Spacelab, and will probably reach several million lines of code for Columbus (all element together). Based on past experience, the total development cost of software can account for about 10 pct to 15 pct of the total space project development cost. The Ada technology may support the strong software engineering principles needed for Columbus, provided that technology is sufficiently mature and industry plans are meeting the Columbus project schedule. Over the past 3 years, Informatique Internationale has conducted a coherent program based on Ada technology assessment studies and experiments, for ESA and CNES. This specific research and development program benefits from 15 years experience in the field of space software development and is supported by the overall software engineering expertise of the company. The assessment and experiments of Ada software engineering by Informatique Internationale are detailed.

  10. An object-oriented classification method of high resolution imagery based on improved AdaTree

    With the popularity of the application using high spatial resolution remote sensing image, more and more studies paid attention to object-oriented classification on image segmentation as well as automatic classification after image segmentation. This paper proposed a fast method of object-oriented automatic classification. First, edge-based or FNEA-based segmentation was used to identify image objects and the values of most suitable attributes of image objects for classification were calculated. Then a certain number of samples from the image objects were selected as training data for improved AdaTree algorithm to get classification rules. Finally, the image objects could be classified easily using these rules. In the AdaTree, we mainly modified the final hypothesis to get classification rules. In the experiment with WorldView2 image, the result of the method based on AdaTree showed obvious accuracy and efficient improvement compared with the method based on SVM with the kappa coefficient achieving 0.9242

  12. Using Ada to implement the operations management system in a community of experts

    Frank, M. S.

    1986-01-01

    An architecture is described for the Space Station Operations Management System (OMS), consisting of a distributed expert system framework implemented in Ada. The motivation for such a scheme is based on the desire to integrate the very diverse elements of the OMS while taking maximum advantage of knowledge based systems technology. Part of the foundation of an Ada based distributed expert system was accomplished in the form of a proof of concept prototype for the KNOMES project (Knowledge-based Maintenance Expert System). This prototype successfully used concurrently active experts to accomplish monitoring and diagnosis for the Remote Manipulator System. The basic concept of this software architecture is named ACTORS for Ada Cognitive Task ORganization Scheme. It is when one considers the overall problem of integrating all of the OMS elements into a cooperative system that the AI solution stands out. By utilizing a distributed knowledge based system as the framework for OMS, it is possible to integrate those components which need to share information in an intelligent manner.

    The regression test selection problem--selecting a subset of a test-suite given a change--has been studied widely over the past two decades. However, the problem has seen little attention when constrained to high-criticality developments and where a "safe" selection of tests need to be chosen. Further, no practical approaches have been presented for the programming language Ada. In this paper, we introduce an approach to solving the selection problem given a combination of both static and dyn...

    2009-09-01

    Full Text Available Abstract Background The Ada-dependent adaptive response system in Escherichia coli is important for increasing resistance to alkylation damage. However, the global transcriptional and translational changes during this response have not been reported. Here we present time-dependent global gene and protein expression profiles following treatment with methyl methanesulfonate (MMS in E. coli W3110 and its ada mutant strains. Results Transcriptome profiling showed that 1138 and 2177 genes were differentially expressed in response to MMS treatment in the wild-type and mutant strains, respectively. A total of 81 protein spots representing 76 nonredundant proteins differentially expressed were identified using 2-DE and LC-MS/MS. In the wild-type strain, many genes were differentially expressed upon long-exposure to MMS, due to both adaptive responses and stationary phase responses. In the ada mutant strain, the genes involved in DNA replication, recombination, modification and repair were up-regulated 0.5 h after MMS treatment, indicating its connection to the SOS and other DNA repair systems. Interestingly, expression of the genes involved in flagellar biosynthesis, chemotaxis, and two-component regulatory systems related to drug or antibiotic resistance, was found to be controlled by Ada. Conclusion These results show in detail the regulatory components and pathways controlling adaptive response and how the related genes including the Ada regulon are expressed with this response.

  5. Generic Ada code in the NASA space station command, control and communications environment

    Mcdougall, D. P.; Vollman, T. E.

    1986-01-01

    The results of efforts to apply powerful Ada constructs to the formatted message handling process are described. The goal of these efforts was to extend the state-of-technology in message handling while at the same time producing production-quality, reusable code. The first effort was initiated in September, 1984 and delivered in April, 1985. That product, the Generic Message Handling Facility, met initial goals, was reused, and is available in the Ada Repository on ARPANET. However, it became apparent during its development that the initial approach to building a message handler template was not optimal. As a result of this initial effort, several alternate approaches were identified, and research is now on-going to identify an improved product. The ultimate goal is to be able to instantly build a message handling system for any message format given a specification of that message format. The problem lies in how to specify the message format, and one that is done, how to use that information to build the message handler. Message handling systems and message types are described. The initial efforts, its results and its shortcomings are detailed. The approach now being taken to build a system which will be significantly easier to implement, and once implemented, easier to use, is described. Finally, conclusions are offered.

  6. ADA1 and NET1 Genes of Yeast Mediate Both Chromosome Maintenance and Mitochondrial $\\rho^{-}$ Mutagenesis

    Koltovaya, N A; Tchekhouta, I A; Devin, A B

    2002-01-01

    An increase in the mitochondrial (mt) rho^- mutagenesis is a well-known respose of yeast cells to mutations in the numerous nuclear genes as well as to various kinds of stress. Notwithstanding the extensive studies during several decades the biological significance of this response is not yet fully understood. The genetic approach to solution of this subject includes the study of genes that are required for the high incidence of spontaneous rho^- mutants. Previously we found that mutations in certain nuclear genes including CDC28, the central cell-cycle regulation gene, may decrease the spontaneous rho^- mutability and simultaneously affect maintenance of the yeast chromosomes and plasmids. The present work provides data on identification of two more genes, resembling CDC28 in this respect. These genes NET1 and ADA1 mediate important regulatory protein-protein interactions in the yeast cell.

  8. Integrating automated structured analysis and design with Ada programming support environments

    Hecht, Alan; Simmons, Andy

    1986-01-01

    Ada Programming Support Environments (APSE) include many powerful tools that address the implementation of Ada code. These tools do not address the entire software development process. Structured analysis is a methodology that addresses the creation of complete and accurate system specifications. Structured design takes a specification and derives a plan to decompose the system subcomponents, and provides heuristics to optimize the software design to minimize errors and maintenance. It can also produce the creation of useable modules. Studies have shown that most software errors result from poor system specifications, and that these errors also become more expensive to fix as the development process continues. Structured analysis and design help to uncover error in the early stages of development. The APSE tools help to insure that the code produced is correct, and aid in finding obscure coding errors. However, they do not have the capability to detect errors in specifications or to detect poor designs. An automated system for structured analysis and design TEAMWORK, which can be integrated with an APSE to support software systems development from specification through implementation is described. These tools completement each other to help developers improve quality and productivity, as well as to reduce development and maintenance costs. Complete system documentation and reusable code also resultss from the use of these tools. Integrating an APSE with automated tools for structured analysis and design provide capabilities and advantages beyond those realized with any of these systems used by themselves.

  10. Determination of Gender and Age Based on Pattern of Human Motion Using AdaBoost Algorithms

    Handri, Santoso; Nomura, Shusaku; Nakamura, Kazuo

    Automated human identification by their walking behavior is a challenge attracting much interest among machine vision researchers. However, practical systems for such identification remain to be developed. In this study, a machine learning approach to understand human behavior based on motion imagery was proposed as the basis for developing pedestrian safety information systems. At the front end, image and video processing was performed to separate foreground from background images. Shape-width was then analyzed using 2D discrete wavelet transformation to extract human motion features. Finally, an adaptive boosting (AdaBoost) algorithm was performed to classify human gender and age into its class. The results demonstrated capability of the proposed systems to classify gender and age highly accurately.

  12. Face detection at a distance with AdaBoost filtering and color-shape information

    Yeom, Seokwon; Lee, Dong-Su

    2013-05-01

    Face detection at a distance is very challenging because the image quality becomes low. This paper discusses a face detection method in the long distance with AdaBoost filtering and a false alarm reduction scheme. The false alarm reduction scheme is based on skin-color testing and variable edge mask filtering. The skin-color test involves the average RGB components of the window, followed by the binary cluster image generation. The binary cluster is composed of the alternative and null pixels according to color. The size of the edge mask is determined by the ellipse covering the binary cluster. The edge mask filters out false alarms by evaluating the contour shape of the object in the window. In the experiments, the false alarm reduction scheme is shown to be effective for face detection in images captured at a distance.

  15. Reliability prediction for the vehicles equipped with advanced driver assistance systems (ADAS and passive safety systems (PSS

    Balbir S. Dhillon

    2012-10-01

    Full Text Available The human error has been reported as a major root cause in road accidents in today’s world. The human as a driver in road vehicles composed of human, mechanical and electrical components is constantly exposed to changing surroundings (e.g., road conditions, environmentwhich deteriorate the driver’s capacities leading to a potential accident. The auto industries and transportation authorities have realized that similar to other complex and safety sensitive transportation systems, the road vehicles need to rely on both advanced technologies (i.e., Advanced Driver Assistance Systems (ADAS and Passive Safety Systems (PSS (e.g.,, seatbelts, airbags in order to mitigate the risk of accidents and casualties. In this study, the advantages and disadvantages of ADAS as active safety systems as well as passive safety systems in road vehicles have been discussed. Also, this study proposes models that analyze the interactions between human as a driver and ADAS Warning and Crash Avoidance Systems and PSS in the design of vehicles. Thereafter, the mathematical models have been developed to make reliability prediction at any given time on the road transportation for vehicles equipped with ADAS and PSS. Finally, the implications of this study in the improvement of vehicle designs and prevention of casualties are discussed.

  18. Microevolution of the chromosomal region of acute disease antigen A (adaA in the query (Q fever agent Coxiella burnetii.

    Dimitrios Frangoulidis

    Full Text Available The acute disease antigen A (adaA gene is believed to be associated with Coxiella burnetii strains causing acute Q fever. The detailed analysis of the adaA genomic region of 23 human- and 86 animal-derived C. burnetii isolates presented in this study reveals a much more polymorphic appearance and distribution of the adaA gene, resulting in a classification of C. burnetii strains of better differentiation than previously anticipated. Three different genomic variants of the adaA gene were identified which could be detected in isolates from acute and chronic patients, rendering the association of adaA positive strains with acute Q fever disease disputable. In addition, all adaA positive strains in humans and animals showed the occurrence of the QpH1 plasmid. All adaA positive isolates of acute human patients except one showed a distinct SNP variation at position 431, also predominant in sheep strains, which correlates well with the observation that sheep are a major source of human infection. Furthermore, the phylogenetic analysis of the adaA gene revealed three deletion events and supported the hypothesis that strain Dugway 5J108-111 might be the ancestor of all known C. burnetii strains. Based on our findings, we could confirm the QpDV group and we were able to define a new genotypic cluster. The adaA gene polymorphisms shown here improve molecular typing of Q fever, and give new insights into microevolutionary adaption processes in C. burnetii.

  19. Software architecture for a distributed real-time system in Ada, with application to telerobotics

    Olsen, Douglas R.; Messiora, Steve; Leake, Stephen

    1992-01-01

    The architecture structure and software design methodology presented is described in the context of telerobotic application in Ada, specifically the Engineering Test Bed (ETB), which was developed to support the Flight Telerobotic Servicer (FTS) Program at GSFC. However, the nature of the architecture is such that it has applications to any multiprocessor distributed real-time system. The ETB architecture, which is a derivation of the NASA/NBS Standard Reference Model (NASREM), defines a hierarchy for representing a telerobot system. Within this hierarchy, a module is a logical entity consisting of the software associated with a set of related hardware components in the robot system. A module is comprised of submodules, which are cyclically executing processes that each perform a specific set of functions. The submodules in a module can run on separate processors. The submodules in the system communicate via command/status (C/S) interface channels, which are used to send commands down and relay status back up the system hierarchy. Submodules also communicate via setpoint data links, which are used to transfer control data from one submodule to another. A submodule invokes submodule algorithms (SMA's) to perform algorithmic operations. Data that describe or models a physical component of the system are stored as objects in the World Model (WM). The WM is a system-wide distributed database that is accessible to submodules in all modules of the system for creating, reading, and writing objects.

  20. BASIC CRITERIA OF IRANIAN COMMERCIAL TOOTHPASTES AND AN ADA APPROVED BRAND (CREST

    2003-03-01

    Full Text Available Introduction: The effectiveness of fluorided toothpastes in reducing dental caries is well-documented, However not all fluorided toothpastes are equally effective. The objective of this study was to compare some essential criteria of six different toothpastes manufactured in Iran with one brand of ADA approved toothpaste (Crest. Methods. Six commercial toothpastes produced in Iran named as Paveh, Puneh, Nasim, Darugar, golpasand and saviz were compared with Crest in three subjects as follows: 1. Amount of fluoride concentration 2. Amount of releasing fluoride 3. Cleaning efficiency. Two first criteria were tested using the potentiometric method with F- Ion specific electrode, and Cleaning efficiency was done by O'Leary index on 60 volunteers (10 for each toothpaste. Results: Fluoride Concentration in Paveh, Puneh, Nasim toothpastes were nearly700PPM,while in three others were much lower. The highest amount of fluoride was seen in Crest (1450 PPM. Cleaning efficiency of Darugar was better than Crest, Paveh, Puneh. Cleaning efficiency of Nasim was the same as Crest and Golpasand and Saviz were weaker than Crest. Discussion: Since at the present time, the most effective, Cost-benefit method for preventive aspects of fluoride, especially in developing countries is obtained by fluoride toothpastes. Manufactures should improve quality of fluoride toothpastes, ensure that all pates maximize Fluoride bioavailability, develop active agents to help better cleaning efficiency and label products clearly with containig fluoride in PPM.

The wet hydrological year 2005–2006 was selected to compare yearly atmospheric chloride bulk deposition and average chloride content in recharge water just above the water table, both deduced from periodical...

  2. Using vertical electrical soundings for characterizing hydrogeological and tectonic settings in Deir El-Adas area, Yarmouk Basin, Syria

    Al-Fares, Walid

    2016-06-01

    The present study is aimed at characterizing the subsurface geological and tectonic structure in Deir El-Adas area, by using Vertical Electrical Sounding survey (VES) and hydrogeological investigations, in order to determine the causes of the failure for the majority of the wells drilled in the area. The survey data was treated in three different approaches including direct VES inversion, pseudo-2D method and horizontal profiling, in order to maximize the reliability of the data interpretation. The results revealed the presence of a local faulted anticline structure at the top of the Paleogene formation, underneath the basaltic outcrops where Deir El-Adas village is situated. The appearance of this subsurface anticline structure has complicated the local hydrogeological situation, and most likely led to limitation of the groundwater recharge in the area. Moreover, the performed piezometric and discharge maps indicated the presence of a notable groundwater watershed, in addition to feeble water productivity of the wells drilled adjacent to Deir El-Adas, mostly related to the subsurface geological and tectonic settings in the area.

  3. Adding delayed recall to the ADAS-cog improves measurement precision in mild Alzheimer's disease: Implications for predicting instrumental activities of daily living.

    Lowe, Deborah A; Balsis, Steve; Benge, Jared F; Doody, Rachelle S

    2015-12-01

    As research increasingly focuses on preclinical stages of Alzheimer's disease (AD), instruments must be retooled to identify early cognitive markers of AD. A supplemental delayed recall subtest for the Alzheimer's Disease Assessment Scale-cognitive (ADAS-cog; Mohs, Rosen, & Davis, 1983; Rosen, Mohs, & Davis, 1984) is commonly implemented, but it is not known precisely where along the spectrum of cognitive dysfunction this subtest yields incremental information beyond what is gained from the standard ADAS-cog, or whether it can improve prediction of functional outcomes. An item response theory approach can analyze this in a psychometrically rigorous way. Seven hundred eighty-eight patients with AD or amnestic complaints or impairment completed a battery including the ADAS-cog and 2 activities of daily living measures. The delayed recall subtest slightly improved the ADAS-cog's measurement precision in the mild range of cognitive dysfunction and increased prediction of instrumental activities of daily living for individuals with subjective memory impairment.

  4. The Spt-Ada-Gcn5 Acetyltransferase (SAGA complex in Aspergillus nidulans.

    Paraskevi Georgakopoulos

    Full Text Available A mutation screen in Aspergillus nidulans uncovered mutations in the acdX gene that led to altered repression by acetate, but not by glucose. AcdX of A. nidulans is highly conserved with Spt8p of Saccharomyces cerevisiae, and since Spt8p is a component of the Spt-Ada-Gcn5 Acetyltransferase (SAGA complex, the SAGA complex may have a role in acetate repression in A. nidulans. We used a bioinformatic approach to identify genes encoding most members of the SAGA complex in A. nidulans, and a proteomic analysis to confirm that most protein components identified indeed exist as a complex in A. nidulans. No apparent compositional differences were detected in mycelia cultured in acetate compared to glucose medium. The methods used revealed apparent differences between Yeast and A. nidulans in the deubiquitination (DUB module of the complex, which in S. cerevisiae consists of Sgf11p, Sus1p, and Ubp8p. Although a convincing homologue of S. cerevisiae Ubp8p was identified in the A. nidulans genome, there were no apparent homologues for Sus1p and Sgf11p. In addition, when the SAGA complex was purified from A. nidulans, members of the DUB module were not co-purified with the complex, indicating that functional homologues of Sus1p and Sgf11p were not part of the complex. Thus, deubiquitination of H2B-Ub in stress conditions is likely to be regulated differently in A. nidulans compared to S. cerevisiae.

    We constructed an ada deletion by gene replacement in a recD1014 strain of Escherichia coli. Characterization of a delta ada-25 recD+ strain revealed the presence of a second DNA methyltransferase activity in E. coli K-12 which transfers a methyl group from methylated DNA to a protein with a molecular weight of 18,000 to 20,000.

  6. Potential for wind energy generation and conversion for rural application: a case study for Ada

    One major indicator of achieving the goals of Vision 2020 is an increased energy use per head, which had a 1993 value of 93 koe (kilograms of oil equivalent) as compared to 299 koe for the least developed middle income nation, and 5,563 koe for Singapore. To satisfy this energy requirement, all potential sources of energy must be harnessed and most importantly, the private sector's involvement in off-grid electric power generation must be encouraged. A cost-benefit analysis, energy payback time and energy ratios have been determined to assess the potential of wind energy generation and conversation at Ada; which has a mean monthly wind speed of 6.23 m/s at a height of 30 m and considered to be adequate to run a small to medium sized wind turbine to generate about 28 kW. The proposal is to install a prototype aero generation system for a small community isolated from the national grid line, and is aimed at demonstrating how a renewable, non-pollutant and independent power source, transformed by means of advanced technology can achieve energy self sufficiency for the community, while avoiding negative impacts on the environment and ensuring cost-effectiveness. The system will consist of an aero-generation unit, storage system and demand electric consumption. The generator will supply the power to batteries through a load rectifier/governor for storage. The demand in electric consumption can be supplied in DC by accumulators or AC by current inverter. The technical features proposed for the aero generation system is a 20 - 30 kW maximum power turbine, a 24 V capacity battery delivery 1625 Ah in 100 h, two charger inverter units connected in parallel with AC synchronized outlet for consumption. The outlet power of each inverter will be 2400 W DC and the estimated time to complete battery load power unit will be 12 h. The projected cost of electricity generated by an optimized scheme is estimated to be 9 cents/kWh, as compared with photovoltaic generation at 5 - 14

  8. An AdaBoost Using a Weak-Learner Generating Several Weak-Hypotheses for Large Training Data of Natural Language Processing

    Iwakura, Tomoya; Okamoto, Seishi; Asakawa, Kazuo

    AdaBoost is a method to create a final hypothesis by repeatedly generating a weak hypothesis in each training iteration with a given weak learner. AdaBoost-based algorithms are successfully applied to several tasks such as Natural Language Processing (NLP), OCR, and so on. However, learning on the training data consisting of large number of samples and features requires long training time. We propose a fast AdaBoost-based algorithm for learning rules represented by combination of features. Our algorithm constructs a final hypothesis by learning several weak-hypotheses at each iteration. We assign a confidence-rated value to each weak-hypothesis while ensuring a reduction in the theoretical upper bound of the training error of AdaBoost. We evaluate our methods with English POS tagging and text chunking. The experimental results show that the training speed of our algorithm are about 25 times faster than an AdaBoost-based learner, and about 50 times faster than Support Vector Machines with polynomial kernel on the average while maintaining state-of-the-art accuracy.

  9. Synthesis of an A-D-A type of molecule used as electron acceptor for improving charge transfer in organic solar cells

    Zhang, Chao-Zhi; Gu, Shu-Duo; Shen, Dan; Yuan, Yang; Zhang, Mingdao

    2016-08-01

    Electron-accepting molecules play an important role in developing organic solar cells. A new type of A-D-A molecule, 3,6-di([7-(5-bromothiophen-2-yl)-1,5,2,4,6,8-dithiotetrazocin-3-yl]thiophen-2-yl)-9-(2-ethylhexyl)carbazole, was synthesized. The lowest unoccupied molecular orbital (LUMO) and highest occupied molecular orbital (HOMO) energy levels are -3.55 and -5.85 eV, respectively. Therefore, the A-D-A type of compound could be used as electron acceptor for fabricating organic solar cell with a high open circuit voltage. Gibbs free energy (-49.2 kJ/mol) reveals that the process of A-D-A acceptor accepting an electron from poly(3-hexylthiophene) at excited state is spontaneous. The value of entropy (118 J/mol) in the process of an electron transferring from P3HT to the A-D-A acceptor at organic interface suggests that electrons generated from separation of electron-hole pairs at donor/acceptor interface would be delocalized efficiently. Therefore, the A-D-A molecule would be a potential acceptor for efficient organic BHJ solar cells.

    2016-04-01

    Sickle cell anemia (SCA) is a hemoglobinopathy characterized by hemolysis and vaso-occlusions caused by rigidly distorted red blood cells. Sickle cell crisis is associated with extracellular release of nucleotides and platelets, which are critical mediators of hemostasis participating actively in purinergic thromboregulatory enzymes system.This study aimed to investigate the activities of purinergic system ecto-enzymes present on the platelet surface as well as CD39 and CD73 expressions on platelets of SCA treated patients. Fifteen SCA treated patients and 30 health subjects (control group) were selected. Ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase), ecto-5'-nucleotidase (E-5'-NT) and ecto-adenosine deaminase (E-ADA) activities were measured in platelets isolated from these individuals. Results demonstrated an increase of 41 % in the E-NTPDase for ATP hydrolysis, 52% for ADP hydrolysis and 60 % in the E-ADA activity in SCA patients (P<0.05); however, a two folds decrease in the CD39 expression in platelets was observed in the same group (P<0.01). The increased E-NTPDase activity could be a compensatory mechanism associated with the low expression of CD39 in platelets. Besides, alteration of these enzymes activities suggests that the purinergic system could be involved in the thromboregulatory process in SCA patients. PMID:27044834

    2014-01-01

    Full Text Available License plate (LP detection is the most imperative part of the automatic LP recognition system. In previous years, different methods, techniques, and algorithms have been developed for LP detection (LPD systems. This paper proposes to automatical detection of car LPs via image processing techniques based on classifier or machine learning algorithms. In this paper, we propose a real-time and robust method for LPD systems using the two-stage adaptive boosting (AdaBoost algorithm combined with different image preprocessing techniques. Haar-like features are used to compute and select features from LP images. The AdaBoost algorithm is used to classify parts of an image within a search window by a trained strong classifier as either LP or non-LP. Adaptive thresholding is used for the image preprocessing method applied to those images that are of insufficient quality for LPD. This method is of a faster speed and higher accuracy than most of the existing methods used in LPD. Experimental results demonstrate that the average LPD rate is 98.38% and the computational time is approximately 49 ms.

    Vukadinovic, D.; van Walsum, T.; Manniesing, R.; van der Lugt, A.; de Weert, T. T.; Niessen, W. J.

    2008-03-01

    A novel 2D slice based fully automatic method for model based segmentation of the outer vessel wall of the common carotid artery in CTA data set is introduced. The method utilizes a lumen segmentation and AdaBoost, a fast and robust machine learning algorithm, to initially classify (mark) regions outside and inside the vessel wall using the distance from the lumen and intensity profiles sampled radially from the gravity center of the lumen. A similar method using the distance from the lumen and the image intensity as features is used to classify calcium regions. Subsequently, an ellipse shaped deformable model is fitted to the classification result. The method achieves smaller detection error than the inter observer variability, and the method is robust against variation of the training data sets.

    Full Text Available Emplazada en la zona de transición sur del segmento de flat-slab pampeano y directamente vinculada a la horizontalización de la placa de Nazca, la faja volcánica terciaria de San Luis delata la migración que experimentó el arco magmático andino a la latitud de los 33º S en tiempos mio-pliocenos. Esta faja volcánica comprende una serie de distritos metalogenéticos de gran importancia en las Sierras Pampeanas de San Luis. Las rocas volcánicas y mineralizaciones de la faja volcánica terciaria se encuentran representadas en los campos volcánicos La Carolina, Cañada Honda - Cerros Largos, Cerros del Rosario y El Morro, dispuestos saltuariamente según una dirección ONO-NO. Las edades K-Ar disponibles indican que el volcanismo se habría iniciado más tempranamente en el sector occidental de esta faja, y que habría finalizado ~ 10 Ma más tarde en la región oriental. El distrito Cañada Honda, el más antiguo y longevo de esta faja volcánica, registra eventos volcánicos e hidrotermales cuyas edades varían entre 12-13 Ma y 7,3 Ma, abarcando facies lávico-hipabisales y volcaniclásticas. Los resultados del análisis estructural demuestran el importante control que, directa o indirectamente, habrían ejercido las estructuras previas en el emplazamiento de las rocas volcánicas y mineralizaciones. Análisis de fábrica deformacional y cinemático han permitido reconocer dos asociaciones volcano-tectónicas diferentes. una de estas asociaciones se vincularía a la reactivación dextral de estructuras paralelas a la foliación del basamento.

  20. The N-terminus region of the putative C2H2 transcription factor Ada1 harbors a species-specific activation motif that regulates asexual reproduction in Fusarium verticillioides.

    Malapi-Wight, Martha; Kim, Jung-Eun; Shim, Won-Bo

    2014-01-01

    Fusarium verticillioides is an important plant pathogenic fungus causing maize ear and stalk rots. In addition, the fungus is directly associated with fumonisin contamination of food and feeds. Here, we report the functional characterization of Ada1, a putative Cys2-His2 zinc finger transcription factor with a high level of similarity to Aspergillus nidulans FlbC, which is required for the activation of the key regulator of conidiation brlA. ADA1 is predicted to encode a protein with two DNA binding motifs at the C terminus and a putative activator domain at the N terminus region. Deletion of the flbC gene in A. nidulans results in "fluffy" cotton-like colonies, with a defect in transition from vegetative growth to asexual development. In this study we show that Ada1 plays a key role in asexual development in F. verticillioides. Conidia production was significantly reduced in the knockout mutant (Δada1), in which aberrant conidia and conidiophores were also observed. We identified genes that are predicted to be downstream of ADA1, based on A. nidulans conidiation signaling pathway. Among them, the deletion of stuA homologue, FvSTUA, resulted in near absence of conidia production. To further investigate the functional conservation of this transcription factor, we complemented the Δada1 strain with A. nidulans flbC, F. verticillioides ADA1, and chimeric constructs. A. nidulans flbC failed to restore conidia production similar to the wild-type level. However, the Ada1N-terminal domain, which contains a putative activator, fused to A. nidulans FlbC C-terminal motif successfully complemented the Δada1 mutant. Taken together, Ada1 is an important transcriptional regulator of asexual development in F. verticillioides and that the N-terminus domain is critical for proper function of this transcription factor.

    2016-04-01

    Climate change (CC) scenarios for the Mediterranean region include an increase in the frequency and intensity of extreme weather events such as drought periods. higher average temperatures and evapotranspiration, combined with the decrease of annual precipitation may strongly affect the sustainability of water resources. In face of these risks, improving water management actions? by anticipating necessary operational measures is required to insure water quantity and quality according to the needs of the populations and irrigation in agriculture. This is clearly the case of the Alentejo region, southern Portugal, where present climatic conditions already pose significant challenges to water resources stakeholders, mainly from the agricultural and the urban supply sectors. With this in mind, the GestAqua.AdaPT project is underway during 2015 and 2016, aiming at analyzing CC impacts until 2100 and develop operational procedures to ensure water needs are adequately satisfied in the Monte Novo and Vigia reservoirs, which supply water for the city of Évora and nearby irrigation systems. Specific project objectives include: a) defining management and operational adaptation strategies aiming to ensure resource sustainability, both quantitatively and qualitatively; b) evaluate future potential costs and available alternatives to the regional water transfer infrastructure linked with the large Alqueva reservoir implemented in 2011; c) defining CC adaptation strategies to reduce irrigation water needs and d) identification of CC adaptation strategies which can be suitable also to other similar water supply systems. The methodology is centered on the implementation of a cascade of modeling tools, allowing the integrated simulation of the multiple variables under analysis. The project is based on CC scenarios resulting from the CORDEX project for 10 combinations of Global and regional climate models (GCMs and RCMs). The study follows by using two of these combinations

  2. Aquifer Recharge Estimation through Atmospheric Chloride Mass Balance at Las Cañadas Caldera, Tenerife, Canary Islands, Spain

    Rayco Marrero-Diaz

    2015-05-01

    Full Text Available The atmospheric chloride mass balance (CMB method was used to estimate net aquifer recharge in Las Cañadas Caldera, an endorheic summit aquifer area about 2000 m a.s.l. with negligible surface runoff, which hosts the largest freshwater reserve in Tenerife Island, Canary Islands, Spain. The wet hydrological year 2005–2006 was selected to compare yearly atmospheric chloride bulk deposition and average chloride content in recharge water just above the water table, both deduced from periodical sampling. The potential contribution of chloride to groundwater from endogenous HCl gas may invalidate the CMB method. The chloride-to-bromide molar ratio was an efficient tracer used to select recharge water samples having atmospheric origin of chloride. Yearly net aquifer recharge was 631 mm year−1, i.e., 69% of yearly precipitation. This result is in agreement with potential aquifer recharge estimated through an independent lumped-parameter rainfall-runoff model operated by the Insular Water Council of Tenerife. This paper illustrates basic procedures and routines to use the CMB method for aquifer recharge in active volcanic oceanic islands having sparse-data coverage and groundwater receiving contribution of endogenous halides.

  4. The covariant description of electric and magnetic field lines of null fields: application to Hopf-Rañada solutions

    van Enk, S. J.

    2013-05-01

    The concept of electric and magnetic field lines is intrinsically non-relativistic. Nonetheless, for certain types of fields satisfying certain geometric properties, field lines can be defined covariantly. More precisely, two Lorentz-invariant 2D surfaces in spacetime can be defined such that magnetic and electric field lines are determined, for any observer, by the intersection of those surfaces with spacelike hyperplanes. An instance of this type of field is constituted by the so-called Hopf-Rañada solutions of the source-free Maxwell equations, which have been studied because of their interesting topological properties, namely, linkage of their field lines. In order to describe both geometric and topological properties in a succinct manner, we employ the tools of geometric algebra (aka Clifford algebra) and use the Clebsch representation for the vector potential as well as the Euler representation for both magnetic and electric fields. This description is easily made covariant, thus allowing us to define electric and magnetic field lines covariantly in a compact geometric language. The definitions of field lines can be phrased in terms of 2D surfaces in space. We display those surfaces in different reference frames, showing how those surfaces change under Lorentz transformations while keeping their topological properties. As a byproduct we also obtain relations between optical helicity, optical chirality and generalizations thereof, and their conservation laws.

    Full Text Available In this paper, the objective is to investigate what contributions depth and intensity information make to the solution of face recognition problem when expression and pose variations are taken into account, and a novel system is proposed for combining depth and intensity information in order to improve face recognition performance. In the proposed approach, local features based on Gabor wavelets are extracted from depth and intensity images, which are obtained from 3D data after fine alignment. Then a novel hierarchical selecting scheme embedded in symbolic linear discriminant analysis (Symbolic LDA with AdaBoost learning is proposed to select the most effective and robust features and to construct a strong classifier. Experiments are performed on the three datasets, namely, Texas 3D face database, Bhosphorus 3D face database and CASIA 3D face database, which contain face images with complex variations, including expressions, poses and longtime lapses between two scans. The experimental results demonstrate the enhanced effectiveness in the performance of the proposed method. Since most of the design processes are performed automatically, the proposed approach leads to a potential prototype design of an automatic face recognition system based on the combination of the depth and intensity information in face images.

    Full Text Available La depresión es uno de los trastornos mentales que más preocupan a nivel mundial. Una de las teorías que más investigación ha suscitado es la teoría cognitiva de la depresión de Beck. El Inventario de Tríada Cognitiva (CTI se ha elaborado para evaluar los diferentes componentes de la tríada cognitiva, si bien la mayoría de sus estudios se han desarrollado en población adulta y adolescente. El objetivo de este trabajo es mostrar evidencias de validez factorial de la versión reducida del CTI, así como el estudio de las propiedades psicométricas del cuestionario en población infantil. En una muestra de 3292 niños de edades entre los 8 y los 13 años (M=9.8;DT=1.24, los resultados mostraron que el mejor ajuste factorial se obtiene con una estructura bifactorial (tríada positiva y tríada negativa. La fiabilidad de las diferentes dimensiones es buena (α=.88 y .92, respectivamente y las evidencias de validez convergente adecuadas. El cuestionario fue evaluado también desde la perspectiva de la Teoría de la Respuesta a los ítems mostrando unas propiedades correctas.

  9. A novel Multi-Agent Ada-Boost algorithm for predicting protein structural class with the information of protein secondary structure.

    Fan, Ming; Zheng, Bin; Li, Lihua

    2015-10-01

    Knowledge of the structural class of a given protein is important for understanding its folding patterns. Although a lot of efforts have been made, it still remains a challenging problem for prediction of protein structural class solely from protein sequences. The feature extraction and classification of proteins are the main problems in prediction. In this research, we extended our earlier work regarding these two aspects. In protein feature extraction, we proposed a scheme by calculating the word frequency and word position from sequences of amino acid, reduced amino acid, and secondary structure. For an accurate classification of the structural class of protein, we developed a novel Multi-Agent Ada-Boost (MA-Ada) method by integrating the features of Multi-Agent system into Ada-Boost algorithm. Extensive experiments were taken to test and compare the proposed method using four benchmark datasets in low homology. The results showed classification accuracies of 88.5%, 96.0%, 88.4%, and 85.5%, respectively, which are much better compared with the existing methods. The source code and dataset are available on request. PMID:26350693

  10. Geometric Feature-Based Facial Expression Recognition in Image Sequences Using Multi-Class AdaBoost and Support Vector Machines

    2013-06-01

    Full Text Available Facial expressions are widely used in the behavioral interpretation of emotions, cognitive science, and social interactions. In this paper, we present a novel method for fully automatic facial expression recognition in facial image sequences. As the facial expression evolves over time facial landmarks are automatically tracked in consecutive video frames, using displacements based on elastic bunch graph matching displacement estimation. Feature vectors from individual landmarks, as well as pairs of landmarks tracking results are extracted, and normalized, with respect to the first frame in the sequence. The prototypical expression sequence for each class of facial expression is formed, by taking the median of the landmark tracking results from the training facial expression sequences. Multi-class AdaBoost with dynamic time warping similarity distance between the feature vector of input facial expression and prototypical facial expression, is used as a weak classifier to select the subset of discriminative feature vectors. Finally, two methods for facial expression recognition are presented, either by using multi-class AdaBoost with dynamic time warping, or by using support vector machine on the boosted feature vectors. The results on the Cohn-Kanade (CK+ facial expression database show a recognition accuracy of 95.17% and 97.35% using multi-class AdaBoost and support vector machines, respectively.

    2014-01-01

    We describe a new genus of grylline cricket, Zebragryllus Desutter-Grandcolas & Cadena-Casteñada n. gen., from the Neotropical Region, using characters of morphology and male genitalia; genitalic characters clearly show that Zebragryllus n. gen. is closely related to Anurogryllus Saussure, 1878. Six species are described as new to science, originating from western (Peru, Colombia) and eastern (French Guiana) Amazonia: Zebragryllus fuscus Desutter-Grandcolas, n. sp., Z. guianensis Desutter-Grandcolas, n. sp., Z. intermedius Desutter-Grandcolas, n. sp., Zebragryllus nauta Desutter-Grandcolas, n. sp., Zebragryllus nouragui Desutter-Grandcolas, n. sp., and Zebragryllus wittoto Desutter-Grandcolas and Cadena-Casteñada, n. sp., type species of the genus. They are characterized by their size, coloration (shining black, most often with white patterns of coloration, hence the genus name), and male and female genitalia. The calling songs of Z. guianensis Desutter-Grandcolas, n. sp., Z. intermedius Desutter-Grandcolas, n. sp., Z. nouragui Desutter-Grandcolas, n. sp., and Z. wittoto Desutter-Grandcolas and Cadena-Casteñada, n. sp. are described. An identification key is proposed for both males and females. PMID:24871163

  12. Spt-Ada-Gcn5-Acetyltransferase (SAGA Complex in Plants: Genome Wide Identification, Evolutionary Conservation and Functional Determination.

    Rakesh Srivastava

    Full Text Available The recruitment of RNA polymerase II on a promoter is assisted by the assembly of basal transcriptional machinery in eukaryotes. The Spt-Ada-Gcn5-Acetyltransferase (SAGA complex plays an important role in transcription regulation in eukaryotes. However, even in the advent of genome sequencing of various plants, SAGA complex has been poorly defined for their components and roles in plant development and physiological functions. Computational analysis of Arabidopsis thaliana and Oryza sativa genomes for SAGA complex resulted in the identification of 17 to 18 potential candidates for SAGA subunits. We have further classified the SAGA complex based on the conserved domains. Phylogenetic analysis revealed that the SAGA complex proteins are evolutionary conserved between plants, yeast and mammals. Functional annotation showed that they participate not only in chromatin remodeling and gene regulation, but also in different biological processes, which could be indirect and possibly mediated via the regulation of gene expression. The in silico expression analysis of the SAGA components in Arabidopsis and O. sativa clearly indicates that its components have a distinct expression profile at different developmental stages. The co-expression analysis of the SAGA components suggests that many of these subunits co-express at different developmental stages, during hormonal interaction and in response to stress conditions. Quantitative real-time PCR analysis of SAGA component genes further confirmed their expression in different plant tissues and stresses. The expression of representative salt, heat and light inducible genes were affected in mutant lines of SAGA subunits in Arabidopsis. Altogether, the present study reveals expedient evidences of involvement of the SAGA complex in plant gene regulation and stress responses.

  13. ADaCGH: A parallelized web-based application and R package for the analysis of aCGH data.

    Ramón Díaz-Uriarte

    Full Text Available BACKGROUND: Copy number alterations (CNAs in genomic DNA have been associated with complex human diseases, including cancer. One of the most common techniques to detect CNAs is array-based comparative genomic hybridization (aCGH. The availability of aCGH platforms and the need for identification of CNAs has resulted in a wealth of methodological studies. METHODOLOGY/PRINCIPAL FINDINGS: ADaCGH is an R package and a web-based application for the analysis of aCGH data. It implements eight methods for detection of CNAs, gains and losses of genomic DNA, including all of the best performing ones from two recent reviews (CBS, GLAD, CGHseg, HMM. For improved speed, we use parallel computing (via MPI. Additional information (GO terms, PubMed citations, KEGG and Reactome pathways is available for individual genes, and for sets of genes with altered copy numbers. CONCLUSIONS/SIGNIFICANCE: ADACGH represents a qualitative increase in the standards of these types of applications: a all of the best performing algorithms are included, not just one or two; b we do not limit ourselves to providing a thin layer of CGI on top of existing BioConductor packages, but instead carefully use parallelization, examining different schemes, and are able to achieve significant decreases in user waiting time (factors up to 45x; c we have added functionality not currently available in some methods, to adapt to recent recommendations (e.g., merging of segmentation results in wavelet-based and CGHseg algorithms; d we incorporate redundancy, fault-tolerance and checkpointing, which are unique among web-based, parallelized applications; e all of the code is available under open source licenses, allowing to build upon, copy, and adapt our code for other software projects.

    José G. Cecatti

    1998-08-01

    Full Text Available Objetivo: identificar o efeito da idade sobre os resultados maternos e perinatais das gestações ocorridas em mulheres com 40 anos ou mais. Métodos: comparamos 494 gestantes com mais de 40 anos, com 988 gestantes com idade entre 20 e 29 anos, pareando-as por paridade. Após controlar possíveis variáveis confundidoras pela análise multivariada, a idade materna avançada manteve associação com a maior prevalência de hipertensão arterial, apresentação anômala, parto por cesária, hemorragia puerperal, índice de Apgar baixo, morte perinatal, natimortalidade e sofrimento fetal intraparto. Resultados: a idade materna avançada esteve isoladamente associada à hipertensão arterial, apresentação anômala, diagnóstico de sofrimento fetal intraparto, parto por cesária e hemorragia puerperal. Com relação aos resultados neonatais, a idade materna avançada estava associada independentemente apenas ao baixo índice de Apgar, morte perinatal e óbito fetal. Conclusões: esses achados mostram a necessidade de assistência obstétrica adequada com atenção especial a esses fatores para procurar melhorar os resultados maternos e perinatais das gestantes com idade avançada.Most authors agree on the negative impact of pregnancy in women with advanced maternal age on maternal and perinatal outcome. However, it is not usual to evaluate if some considered risk factors are only confounders because they are present in women over forty years. In order to identify the isolated effect of age on maternal and perinatal outcome of pregnancies in women over forty, 494 pregnancies from this age group were compared to 988 pregnancies among women aged 20 to 29 years, matched by parity. After controlling possible confounding variables through multivariate analysis, advanced maternal age maintained its association with a higher prevalence of hypertension, malpresentation, cesarean section, postpartum hemorrhage, low Apgar score, perinatal death, late fetal

    Full Text Available OBJECTIVE: Adenosine may play a role in the pathophysiology of schizophrenia, since it modulates the release of several neurotransmitters such as glutamate, dopamine, serotonin and acetylcholine, decreases neuronal activity by pos-synaptic hyperpolarization and inhibits dopaminergic activity. Adenosine deaminase participates in purine metabolism by converting adenosine into inosine. The most frequent functional polymorphism of adenosine deaminase (22G→A (ADA1*2 exhibits 20-30% lower enzymatic activity in individuals with the G/A genotype than individuals with the G/G genotype. The aim of this study was to evaluate the ADA polymorphism 22G→A (ADA1*2 in schizophrenic patients and healthy controls. METHOD: The genotypes of the ADA 22G→A were identified with allele-specific PCR strategy in 152 schizophrenic patients and 111 healthy individuals. RESULTS: A significant decrease in the frequency of the G/A genotype was seen in schizophrenic patients (7/152 - 4.6% relative to controls (13/111 - 11.7%, p = 0.032, OR = 2.6. CONCLUSION: These results suggest that the G/A genotype associated with low adenosine deaminase activity and, supposingly, with higher adenosine levels is less frequent among schizophrenic patients.OBJETIVO: A adenosina pode ter um papel importante na fisiopatologia da esquizofrenia, uma vez que modula a liberação de vários neurotransmissores, tais como glutamato, dopamina, serotonina e acetilcolina, diminui a atividade neuronal por hiperpolarização pós-sináptica e inibe a atividade dopaminérgica. A adenosina desaminase participa do metabolismo das purinas pela conversão de adenosina em inosina. O mais frequente polimorfismo funcional da adenosina desaminase (22G →A (ADA1*2 exibe uma diminuição de 20-30% da atividade funcional em indivíduos com genótipo G/A quando comparados com indivíduos com o genótipo G/G.

    2010-12-01

    Full Text Available Emplazada en la zona de transición sur del segmento de flat-slab pampeano y directamente vinculada a la horizontalización de la placa de Nazca, la faja volcánica terciaria de San Luis delata la migración que experimentó el arco magmático andino a la latitud de los 33º S en tiempos mio-pliocenos. Esta faja volcánica comprende una serie de distritos metalogenéticos de gran importancia en las Sierras Pampeanas de San Luis. Las rocas volcánicas y mineralizaciones de la faja volcánica terciaria se encuentran representadas en los campos volcánicos La Carolina, Cañada Honda - Cerros Largos, Cerros del Rosario y El Morro, dispuestos saltuariamente según una dirección ONO-NO. Las edades K-Ar disponibles indican que el volcanismo se habría iniciado más tempranamente en el sector occidental de esta faja, y que habría finalizado ~ 10 Ma más tarde en la región oriental. El distrito Cañada Honda, el más antiguo y longevo de esta faja volcánica, registra eventos volcánicos e hidrotermales cuyas edades varían entre 12-13 Ma y 7,3 Ma, abarcando facies lávico-hipabisales y volcaniclásticas. Los resultados del análisis estructural demuestran el importante control que, directa o indirectamente, habrían ejercido las estructuras previas en el emplazamiento de las rocas volcánicas y mineralizaciones. Análisis de fábrica deformacional y cinemático han permitido reconocer dos asociaciones volcano-tectónicas diferentes. una de estas asociaciones se vincularía a la reactivación dextral de estructuras paralelas a la foliación del basamento. La asociación principal estaría vinculada con el desarrollo de dos depresiones volcano-tectónicas alineadas en dirección ONO-NO. Sus estructuras principales, de orientación ONO-NO, revelan componentes de desplazamiento senestral y normal tanto a escala del distrito Cañada Honda como de la faja volcánica terciaria.

    Antônio Carlos Pereira-Barretto

    2013-03-01

    Full Text Available FUNDAMENTO: A insuficiência cardíaca (IC é doença que cursa com má evolução, especialmente naqueles com IC avançada. A dosagem de peptídeo natriurético tipo B(BNP, ao lado da utilidade no diagnóstico da descompensação cardíaca, vem se mostrando útil na avaliação prognóstica. OBJETIVOS: Verificar se os níveis de BNP identificam quais pacientes evoluiriam pior e se o BNP seria fator independente de mortalidade considerando-se idade, sexo, funções cardíaca e renal e etiologia da cardiopatia. MÉTODOS: 189 pacientes com IC avançada em classe funcional III/IV foram estudados. Todos tinham disfunção sistólica e dosaram-se os níveis de BNP na hospitalização. Analisaram-se as variáveis relacionadas com a mortalidade através de análises univariada e multivariada. RESULTADOS: Os níveis de BNP foram mais elevados nos pacientes que morreram no primeiro ano de seguimento (1.861,9 versus 1.408,1 pg/dL; p = 0,044 e nos chagásicos (1.985 versus 1.452 pg/mL; p = 0,001, e esses pacientes chagásicos tiveram maior mortalidade no primeiro ano de seguimento (56% versus 35%; p = 0,010. Pela curva ROC, o valor de BNP de 1.400 pg/mL foi o melhor preditor de eventos, estando os valores elevados associados a FEVE mais baixa (0,23 versus 0,28; p = 0,002 e maior grau de disfunção renal (ureia média 92 versus 74,5 mg/dL; p = 0,002. CONCLUSÃO: Na IC avançada, os níveis elevados de BNP identificam pacientes com maior potencial de pior evolução. Os pacientes chagásicos apresentam níveis mais elevados de BNP do que as outras etiologias e têm pior evolução.

  7. Estudo exaustivo e sistemático de erros nas provas da olimpíada brasileira de astronomia - resultados preliminares

    2003-08-01

    A Olimpíada Brasileira de Astronomia (OBA) contou, em sua quinta edição, com a participação de mais de 60 mil alunos dos ensinos fundamental e médio de praticamente todo o território nacional. Uma das formas de controle que a sua coordenação nacional possui sobre a correção, levada a cabo pelos professores que as aplicaram, é a do envio, por parte destes professores, das 10 melhores provas de cada um dos três níveis nos quais a Olimpíada é realizada. Assim, e dado ao caráter discursivo das provas da Olimpíada, a sua coordenação nacional dispõe de um vasto acervo sobre as concepções, certas ou erradas, dos alunos que dela participaram. Este conjunto de dados jamais fora explorado até o presente trabalho que pretende ser, neste sentido, inaugural. Nas provas dos níveis I e II da V OBA, que abrangem todo o conjunto do ensino fundamental, uma das questões versava sobre a noção que os alunos tinham sobre como os habitantes da Terra situam-se sobre sua superfície. Fizemos um estudo sistemático das respostas a esta questão. Primeiramente, todas as modalidades de erros foram levantadas; em seguida, realizamos uma distribuição por idade tanto do índice de acerto como da ocorrência e da distribuição de cada erro. Como resultado, obtivemos que, em ambos os níveis: 1) as concepções errôneas não se apresentam distribuídas aleatoriamente; 2) há uma concentração no tipo de erro apresentado; 3) há uma tendência de progressivo acerto com relação à idade quando os dados são considerados em termos nacionais; 4) esta tendência nacional é fraca ou mesmo não é verificada em alguns dos estados com maior patamar de acerto.

    The purpose of this study is to assess the reproducibility of hippocampal atrophy rate measurements of commonly used fully-automated algorithms in Alzheimer disease (AD). The reproducibility of hippocampal atrophy rate for FSL/FIRST, AdaBoost, FreeSurfer, MAPS independently and MAPS combined with the boundary shift integral (MAPS-HBSI) were calculated. Back-to-back (BTB) 3D T1-weighted MPRAGE MRI from the Alzheimer's Disease Neuroimaging Initiative (ADNI1) study at baseline and year one were used. Analysis on 3 groups of subjects was performed - 562 subjects at 1.5T, a 75 subject group that also had manual segmentation and 111 subjects at 3T. A simple and novel statistical test based on the binomial distribution was used that handled outlying data points robustly. Median hippocampal atrophy rates were -1.1%/year for healthy controls, -3.0%/year for mildly cognitively impaired and -5.1%/year for AD subjects. The best reproducibility was observed for MAPS-HBSI (1.3%), while the other methods tested had reproducibilities at least 50% higher at 1.5T and 3T which was statistically significant. For a clinical trial, MAPS-HBSI should require less than half the subjects of the other methods tested. All methods had good accuracy versus manual segmentation. The MAPS-HBSI method has substantially better reproducibility than the other methods considered. PMID:27179313

  20. Penalized linear discriminant analysis and Discrete AdaBoost to distinguish human hair metal profiles: The case of adolescents residing near Mt. Etna.

    Abbruzzo, A; Tamburo, E; Varrica, D; Dongarrà, G; Mineo, A

    2016-06-01

    The research focus of the present paper was twofold. First, we tried to document that human intake of trace elements is influenced by geological factors of the place of residence. Second, we showed that the elemental composition of human hair is a useful screening tool for assessing people's exposure to potentially toxic substances. For this purpose, we used samples of human hair from adolescents and applied two robust statistical approaches. Samples from two distinct geological and environmental sites were collected: the first one was characterized by the presence of the active volcano Mt. Etna (ETNA group) and the second one lithologically made up of sedimentary rocks (SIC group). Chemical data were statistically processed by Penalized Linear Discriminant Analysis (pLDA) and Discrete AdaBoost (DAB). The separation between the two groups turned out well, with few overlaps accounting for less than 5%. The chemical variables that better distinguished ETNA group from SIC group were As, Cd, Co, Li, Mo, Rb, Sr, U and V. Both pLDA and DAB allowed us to characterize the elements most closely related to the volcanic contribution (As, U and V) and those (Cd, Co, Li, Mo, Rb and Sr) prevalently influenced by the geology of the area where SIC samples were collected. We conclude that the geological characteristics of the area of residence constitute a key factor in influencing the potential exposure to trace elements. Hair analysis coupled with robust statistical methods can be effectively used as a screening procedure to identify areas at great environmental risk. PMID:27015569

    Full Text Available Para que a adoção de Tecnologia Avançada da Manufatura (AMT possa, de fato, proporcionar vantagens competitivas às empresas, faz-se necessário que essas tecnologias sejam selecionadas segundo critérios que considerem aspectos estratégicos. As características organizacionais de uma empresa influenciam sobremaneira o processo de adoção de AMT, de tal forma que se faz necessário desenvolver recomendações para a revisão do projeto organizacional. O presente trabalho propõe um processo para a geração de tais recomendações, através de uma metodologia denominada de "refinamentos sucessivos". Como resultado deste processo de "refinamentos sucessivos" obtém-se um conjunto de recomendações para a revisão do projeto organizacional, baseados em requisitos estabelecidos pelo processo de adoção de AMT. Essas recomendações constituem um conjunto de decisões a serem tomadas acerca do projeto organizacional para adequá-lo às demandas de uma nova tecnologia a ser introduzida, ou seja, a implementação de AMT.In order for the adoption of Advanced Manufacturing Technology (AMT to provide competitive advantages to the companies, it is necessary to select these technologies according to criteria that consider strategic aspects.

    为了从微观的角度了解改良ADA脱硫机理,采用循环伏安法研究了改良ADA脱硫工艺中含硫物质与ADA的反应机理。结果表明,溶液中ADA可以直接和仿H2S吸收液中的含硫物质发生反应,该反应过程分为初始快速反应阶段(前5s内)和慢速稳定反应阶段(5s之后)。通过对慢速稳定反应阶段中含硫物质和ADA的反应动力学研究表明,仿H2S吸收液中含硫物质和ADA反应为一级反应,速率常数为0.00175s-1。%In order to understand the desulfurization mechanism at microcosmic level, the reaction mechanism of sulfur-containing substances with ADA in the modified stretford process was investigated by using the cyclic voltammetry. The results showed that the ADA could directly react with sulfur-containing substances in the simulated H2S-absorbing liquid. The reaction process had a initial rapid reaction period of 5 seconds and a slow reaction period after 5 seconds. The kinetic study on the slow reaction period indicated that the reaction of sulfur-containing substances with ADA is a first-order reaction with the rate constant of 0.00175s-1.

    Full Text Available RACIONAL: A neoplasia de esôfago está entre as 10 mais incidentes no Brasil. O diagnóstico é geralmente tardio e a sobrevida média é de 4 a 6 meses, independente da terapêutica. O alívio da disfagia e a melhora da qualidade de vida são os objetivos principais da terapêutica paliativa. OBJETIVO: Avaliar a qualidade de vida e a paliação da disfagia obtida com diferentes tipos de tratamento oferecidos aos pacientes com neoplasia avançada de esôfago. PACIENTES E MÉTODO: Avaliação prospectiva de 38 pacientes com neoplasia avançada de esôfago, com disfagia, sem possibilidade de tratamento curativo, entre setembro de 2001 a junho de 2005. Os pacientes foram alocados aleatoriamente, de acordo com a disponibilidade da terapia ou preferência do paciente ou do médico responsável, sendo 14 tratados com colocação de prótese (9 metálicas auto-expansíveis, 4 plásticas e 1 plástica auto-expansível, 4 com cirurgia paliativa, 8 com gastrostomia (7 cirúrgicas e 1 endoscópica e 12 com sonda nasoenteral. RESULTADOS: Houve melhora do índice médio de disfagia em 30 dias em todos os grupos, exceto no da gastrostomia. A colocação da prótese de esôfago melhorou a disfagia de forma estatisticamente significante em relação às outras terapias paliativas. A qualidade de vida avaliada pela mediana do índice de Karnofsky não apresentou melhora em nenhum grupo de pacientes. O número de internações necessárias não foi diferente entre os grupos. A duração média das internações foi maior no grupo de tratamento cirúrgico (42 dias, embora sem diferença significativa. Não houve diferença na sobrevida média dos pacientes, independente do tipo de tratamento. CONCLUSÃO: A paliação ideal para todos os casos não existe. O método deve ser individualizado para cada paciente. O tratamento cirúrgico paliativo é o mais oneroso, devido ao prolongado tempo médio de internação desses pacientes.

    Júnia Helena Porto Barbosa

    2009-02-01

    Full Text Available A geração dos produtos de glicação avançada é um dos principais mecanismos desencadeadores das doenças associadas ao diabetes mellitus, que incluem cardiopatia, retinopatia, neuropatia e nefropatia. Esta revisão tem como objetivo analisar o papel dos produtos de glicação avançada presentes na alimentação como mediadores das complicações diabéticas e apresentar estratégias de redução de sua ingestão. Para tanto, foram realizados levantamentos em bancos de dados de publicações da área, dos últimos 15 anos, considerando-se artigos de revisão, estudos clínicos e experimentais. Os produtos de glicação avançada são um grupo heterogêneo de moléculas formadas a partir de reações não enzimáticas entre grupamentos amino e carbonilo, sendo a carboximetilisina e a pentosidina exemplos de produtos de glicação avançada identificados em alimentos e in vivo. Os produtos de glicação avançada ingeridos são absorvidos, somando-se aos endógenos no surgimento e na progressão das diversas complicações do diabetes, existindo uma correlação direta entre o consumo e a concentração sanguínea. Sua restrição na alimentação se correlaciona à supressão dos níveis séricos de marcadores de doença vascular e de mediadores inflamatórios diretamente envolvidos no desenvolvimento das degenerações diabéticas. As atuais orientações dietéticas centram-se na proporção em nutrientes e na restrição energética, sem considerar o risco da ingestão de produtos de glicação avançada formados durante o processamento dos alimentos. Recomendações simples, como a utilização de temperaturas baixas por períodos mais curtos, em presença de água, no preparo de alimentos, exercem efeitos importantes na prevenção das complicações do diabetes. O estudo dos mecanismos envolvidos na geração de produtos de glicação avançada e das propriedades anti-glicação de compostos presentes nos alimentos podem contribuir com

    A path to new synthons for application in crystal engineering is the replacement of a strong hydrogen-bond acceptor, like a C=O group, with a weaker acceptor, like a C=S group, in doubly or triply hydrogen-bonded synthons. For instance, if the C=O group at the 2-position of barbituric acid is changed into a C=S group, 2-thiobarbituric acid is obtained. Each of the compounds comprises two ADA hydrogen-bonding sites (D = donor and A = acceptor). We report the results of cocrystallization experiments of barbituric acid and 2-thiobarbituric acid, respectively, with 2,4-diaminopyrimidine, which contains a complementary DAD hydrogen-bonding site and is therefore capable of forming an ADA/DAD synthon with barbituric acid and 2-thiobarbituric acid. In addition, pure 2,4-diaminopyrimidine was crystallized in order to study its preferred hydrogen-bonding motifs. The experiments yielded one ansolvate of 2,4-diaminopyrimidine (pyrimidine-2,4-diamine, DAPY), C4H6N4, (I), three solvates of DAPY, namely 2,4-diaminopyrimidine-1,4-dioxane (2/1), 2C4H6N4·C4H8O2, (II), 2,4-diaminopyrimidine-N,N-dimethylacetamide (1/1), C4H6N4·C4H9NO, (III), and 2,4-diaminopyrimidine-1-methylpyrrolidin-2-one (1/1), C4H6N4·C5H9NO, (IV), one salt of barbituric acid, viz. 2,4-diaminopyrimidinium barbiturate (barbiturate is 2,4,6-trioxopyrimidin-5-ide), C4H7N4(+)·C4H3N2O3(-), (V), and two solvated salts of 2-thiobarbituric acid, viz. 2,4-diaminopyrimidinium 2-thiobarbiturate-N,N-dimethylformamide (1/2) (2-thiobarbiturate is 4,6-dioxo-2-sulfanylidenepyrimidin-5-ide), C4H7N4(+)·C4H3N2O2S(-)·2C3H7NO, (VI), and 2,4-diaminopyrimidinium 2-thiobarbiturate-N,N-dimethylacetamide (1/2), C4H7N4(+)·C4H3N2O2S(-)·2C4H9NO, (VII). The ADA/DAD synthon was succesfully formed in the salt of barbituric acid, i.e. (V), as well as in the salts of 2-thiobarbituric acid, i.e. (VI) and (VII). In the crystal structures of 2,4-diaminopyrimidine, i.e. (I)-(IV), R2(2)(8) N-H...N hydrogen-bond motifs are preferred and, in two

    Full Text Available A reflexão sobre desafios transnacionais de segurança enquadra-se num contexto de esbatimento do tradicional conceito de Estado, centrado num território delimitado por fronteiras e com o monopólio da violência física legítima. No contexto africano o debate assume duas dimensões importantes: vontade política e capacidade de o Estado proteger os seus cidadãos. Este artigo sugere que pelo menos a parte da vontade política está em grande medida condicionada pelo entendimento do Estado sobre a cidadania, num contexto em que a etnicidade constitui um elemento estruturante de relações e pertenças muito mais forte e de natureza transnacional. Daí que os movimentos de migrações forçadas devam ser entendidos num contexto societal, ou seja, tendo como enfoque o papel das populações e dos contextos locais de violência e paz e dinâmicas regionais no acolhimento ou rejeição dos que fogem. Em todo este processo importa perceber a forma como as migrações forçadas são construídas enquanto factor ou consequência da insegurança.The debate on transnational challenges to security is framed within the context of the blurring of the traditional concept of state, centred on a territory delimited by borders and with a monopoly of legitimate physical violence. In the African context the debate is guided by two important dimensions: political will and the capacity of the state to protect its citizens. This article suggests that at least the political will dimension is largely constrained by the interpretation of the state on issues of citizenship, in a context where ethnicity is a structuring element of relations and belongings much more powerful than that of citizenship and encompasses the transnational dimension of such relations. Therefore, it is argued that forced migrations should be framed within a societal context, focusing on the role of local populations and local contexts of violence and peace as well as the regional dynamics of

    Full Text Available The aim of this study was to evaluate the clinical performance (retention rate of fiber-reinforced composite fixed partial dentures (FPDs. Polyethylene fiber (Ribbond® was used combined with restorative composite during FPDs fabrication. FPDs were placed in thirteen patients in a private clinic. Nineteen FPDs were evaluated. The prosthetic space was filled with only one pontic using extracted teeth (2 cases, acrylic resin teeth (11 cases, or with composite resin (6 cases, combined with Polyethylene fiber. The clinical criterion used was based on retention rate of FPDs. If FPDs were in function in the mouth at the time of examination without previous repair they were classified as Complete Survival (CS restorations. A classification of Survival with Rebonding (SR was assigned in the event of an adhesive failure, but after rebonding the FPD still remained under evaluation. Treatment was classified as a Failure (F if the FPD restoration was lost. The time of evaluation was 41.15 months (±15.13. The FPDs evaluated were retained (CS=94.75%, and no failure was found except for in one situation which required rebonding (SR=5.25%.

Apresentar comparações entre as formulações analíticas dos mais importantes códigos e recomendações disponíveis na literatura e avaliar os coeficientes de segurança propostos utilizando dados obtidos de resultados provenientes de investigações experimentais é o objetivo deste trabalho. Desenvolveu-se uma série de comparações entre as normas e recomendações NBR 6118 (2014, EUROCODE 2 (1992, ACI 318M (2011, ACI 440.2R (2008, fib BULLETIN 14 - TG 9.3 (2001 e CNR-DT 200 (2004. A base de dados foi feita pelos resultados experimentais de 30 vigas de concreto armado reforçadas. Observou-se que algumas normas são mais restritivas em relação às outras, oferecendo uma menor contribuição ao reforço, sendo, portanto, mais seguras. As informações permitiram demonstrar através de gráficos que o comportamento esperado, possível devido ao uso dos coeficientes de segurança, mantiveram os valores de cálculo muito abaixo dos valores de ruptura. Este trabalho pretende contribuir para a melhor utilização da combinação das principais normas utilizadas.

Como gerador de tudo o que existe, Urano (Céu abrigava em seu bojo as forças naturais que indicavam a presença dos deuses e dos titãs. Nessa direção, a observação de seus objetos - os metéoroi - era de inestimável valor para a cultura homérica. Homero iluminou as ações dos heróis da Ilíada por meio de analogias com os objetos celestes, os quais mais tarde no século IV a.C. mobilizariam os olhares de Platão e de Aristóteles. Os meteóroi, "objetos naturais suspensos no ar", foram descritos pelo poeta através de certas funções narrativas da epopeia, estruturando assim uma protometeorologia homérica. O presente trabalho procura então levantar certos padrões expressivos encontrados durante a leitura da Ilíada e algumas considerações que os problematizam de modo a iluminar o entendimento sobre tema.Palavras-chave: Mundo homérico – Meteorologia e astronomia – Crença – Mecanismos de linguagem. Résumé: Dans la Grèce antique, le ciel était personnifié comme l'un des dieux primordiaux du panthéon hellénique.

    2013-03-01

    Full Text Available FUNDAMENTO: A insuficiência cardíaca (IC é doença que cursa com má evolução, especialmente naqueles com IC avançada. A dosagem de peptídeo natriurético tipo B(BNP, ao lado da utilidade no diagnóstico da descompensação cardíaca, vem se mostrando útil na avaliação prognóstica. OBJETIVOS: Verificar se os níveis de BNP identificam quais pacientes evoluiriam pior e se o BNP seria fator independente de mortalidade considerando-se idade, sexo, funções cardíaca e renal e etiologia da cardiopatia. MÉTODOS: 189 pacientes com IC avançada em classe funcional III/IV foram estudados. Todos tinham disfunção sistólica e dosaram-se os níveis de BNP na hospitalização. Analisaram-se as variáveis relacionadas com a mortalidade através de análises univariada e multivariada. RESULTADOS: Os níveis de BNP foram mais elevados nos pacientes que morreram no primeiro ano de seguimento (1.861,9 versus 1.408,1 pg/dL; p = 0,044 e nos chagásicos (1.985 versus 1.452 pg/mL; p = 0,001, e esses pacientes chagásicos tiveram maior mortalidade no primeiro ano de seguimento (56% versus 35%; p = 0,010. Pela curva ROC, o valor de BNP de 1.400 pg/mL foi o melhor preditor de eventos, estando os valores elevados associados a FEVE mais baixa (0,23 versus 0,28; p = 0,002 e maior grau de disfunção renal (ureia média 92 versus 74,5 mg/dL; p = 0,002. CONCLUSÃO: Na IC avançada, os níveis elevados de BNP identificam pacientes com maior potencial de pior evolução. Os pacientes chagásicos apresentam níveis mais elevados de BNP do que as outras etiologias e têm pior evolução.BACKGROUND: Heart failure (HF is a condition with poor outcome, especially in advanced cases.

While the original design of a language has the distinct advantage of filling a blank page, the revision of a language needs to abide by a number of constraints that limit the degree of design freedom. These constraints are both of a technical and a nontechnical nature. In a language revision, each desired change has both a benefit and a cost. Deciding which changes to incorporate into the language becomes a cost/benefit analysis within the framework ...

    Full Text Available Research deals with aspects in conductive/convective drying of long fiber cellulose sheets over heated surfaces under forced air conditions provided by an adjustable blower. Its aim is to analyze the influence of drying (heated surface temperature and air velocity in the behavior of the drying curves, drying rate curves and samples temperature profiles. Influence was analyzed through the classic proposal of two drying rate periods. The constant drying rate dependence upon surface temperature and air condition was studied from a heat transfer point of view. Heat transferred by the heated surface is used partly to evaporate water from solid and partly it is lost into ambient air. For the falling rate period, a linear (proportional reduction of the constant rate was verifiedEste trabalho teve como objetivo analisar a secagem condutiva/convectiva de folhas de celulose de fibra longa, na operação com ar ambiente em convecção forçada para diferentes condições operacionais da temperatura de secagem (superfície metálica aquecida e da velocidade do ar na superfície das amostras. Foram estudados aspectos da cinética de secagem, a partir do levantamento das curvas de secagem, taxa de secagem e perfis de temperatura, sendo seu comportamento avaliado através da abordagem clássica de dois períodos de secagem. Os valores encontrados para as taxas de secagem do período constante foram ajustados através de um balanço térmico para esta fase, ou seja, pela equivalência entre o calor transferido entre a superfície aquecida, as amostras de celulose e o ar, e o calor envolvido no processo de evaporação. Já para o período de taxa decrescente, foi verificada a possibilidade de aplicação de uma redução linear da taxa constante

    Full Text Available Se presenta una el caso de paciente joven, con tríada de Carney incompleta que cursa hipertensión arterial de dos años de evolución y anemia ferropénica grave por pérdida crónica de sangre por tubo digestivo, con tumores gástricos múltiples y paraganglioma pararrenal. No presenta aún desarrollo de condromas pulmonares visibles por tomografía axial computada. En nuestra paciente el paraganglioma no resultó funcionante. Resaltamos que la presencia de tumores gástricos múltiples en un adulto joven debe sugerir la posibilidad de tumores estromales (GIST, cuyo diagnóstico por biopsia endoscópica es difícil debido a su localización profunda, situada en las capas musculares de la pared gástrica. Asimismo queremos remarcar la importancia de las técnicas de marcación descriptas para el diagnóstico preciso. El seguimiento debe ser constante dado el pronóstico incierto de estos tumores. Los condromas pulmonares pueden aparecer años después de la resección del GIST y ser confundidos con metástasis del GIST.The case of young woman with arterial hypertension diagnosed two years before, is here presented; she had a ferropenic anemia caused by digestive loss of blood. Multiple gastric tumors and pararenal non functioning paraganglioma were found. No chondromas were detected. An incomplete Carney’s Triad was diagnosed. We remark that multiple gastric tumors in a young adult suggest the possibility of gastrointestinal stromal tumors (GIST Endoscopic biopsy frequently is not effective because these tumors are deep placed in the muscular gastric layers. The importance of specific techniques for a positive diagnosis are emphasized. Continuous follow up is needed because these tumors have uncertain prognosis. Lung chondromas may appear years later after the GIST was removed and might be confused with GIST metastases.

    Full Text Available OBJETIVO: Avaliar o fluxo, a pressão de ruptura, a necessidade de pontos de reforço, em artérias suturadas, reforçadas ou não com selante de fibrina após uma secção transversal. MÉTODO: Utilizou-se como selante o Tissucol®. Dezessete suínos, Landrace ligth, pesando entre 15 e 20 kg, tiveram suas artérias femorais e carótidas seccionadas após heparinização, anastomosadas em plano único contínuo de prolene 7-0. Usamos 68 amostras arteriais, 34 no grupo tratamento e 34 no grupo controle. Uma artéria carótida e uma femoral receberam, selante de fibrina, aleatoriamente; o lado contralateral foi o controle. Anotava-se a necessidade e o número de pontos de reforço. Após 10 minutos da infusão de protamina, sacrificavam-se os animais, cateterizavam-se as artérias. Estas artérias foram mensuradas, colocadas num fluxômetro, onde se avaliava a velocidade do fluxo. As artérias foram submetidas à infusão de ar, com pressões sucessivamente mais elevadas, mergulhadas em solução de NaCl a 0,9%, observando-se o primeiro vazamento aéreo. Analisaram-se os dados estatisticamente. RESULTADOS: Os diâmetros externos e a espessura das artérias, além da pressão de ruptura e número de amostra com ruptura superior a 200mmHg, foram semelhantes. Contudo, o selante diminuiu o número de pontos de reforço. CONCLUSÃO: O selante de fibrina reduz a necessidade de pontos adicionais.OBJECTIVES: To evaluate the flow, tear pressure, the need of reinforcement stitches in sutured arteries reinforced or not using fibrin sealant after a cross-section. METHOD: Tissucol® fibrin sealant was used.

    Full Text Available Foram avaliados métodos alternativos de restrição alimentar qualitativa em comparação à técnica convencional de muda forçada. Utilizaram-se 480 galinhas Babcock de 78 semanas distribuídas em três níveis de restrição alimentar (100, 75 e 50% e três percentuais de redução de peso corporal (15, 20 e 25%, cada um com cinco repetições de 32 aves. Quando as aves atingiram o percentual de redução de peso corporal, determinaram-se o volume globular, os percentuais de ovário, oviduto, moela, intestino e gordura abdominal e o comprimento de oviduto. A partir do 28º dia e durante cinco períodos de 28 dias, observaram-se as características quantitativas e qualitativas de produção pós-muda. O maior período de restrição foi observado no nível de 50% e proporcionou menores percentuais de gordura abdominal (0,66%, ovário (0,60%, oviduto (0,77% e comprimento de oviduto (32 cm. O percentual de produção de ovos foi maior no primeiro período para as aves submetidas aos métodos de 75 e 100% de restrição com 15 e 20% de redução de peso, respectivamente. Entretanto, para as aves com 50% de restrição e 25% de redução de peso, as maiores produções (86,80 e 83,20% ocorreram no quarto e quinto períodos. A restrição alimentar qualitativa, em 50% da dieta com ração e casca de arroz, por ser menos agressiva, proporciona melhores condições de bem-estar e facilita o manejo da granja.Alternative methods were assessed of qualitative feed restriction compared to the conventional forced molt technique. Four hundred and eighty Babcock hens were used distributed in three levels of feed restriction (100, 75 and 50% and three body weight reduction percentages (15, 20 and 25%, with five replications of 32 hens.

    Full Text Available O objetivo deste estudo foi investigar os efeitos de diferentes padrões respiratórios no desempenho e na organização temporal das braçadas do nado "Crawl" de atletas de elite. Vinte e um jovens atletas do gênero masculino participaram de forma voluntária do estudo. Eles foram filmados nadando 25 m do nado "Crawl", em velocidade máxima, em quatro condições de respiração: inspiração para o lado preferido (LP; para o lado não preferido (LNP; bilateral (B; e, sem respiração (S. Duas filmadoras digitais (60 fps captaram as imagens que foram analisadas através do "software" Kinovea 0.8.7 nos 10 metros centrais do percurso. Para análise foram consideradas medidas de desempenho e de organização temporal das braçadas. Os resultados permitiram concluir que o padrão respiratório afeta o desempenho de atletas jovens de elite. Mostraram que, em termos de velocidade, tempo, frequência e comprimento de braçada, é mais vantajosa a condição de nadar "Crawl" em apneia (S que em qualquer das condições com inspiração (B, LP e LNP. Portanto, o padrão preferido de respiração, não necessariamente, corresponde ao mais eficiente em termos do desempenho. Assim, professores e técnicos de Natação deveriam incentivar a prática e o emprego do padrão em apneia como estratégia tática para nadadores velocistas. Em relação à braçada, os resultados mostraram que diante da modificação do padrão respiratório, nadadores peritos jovens mantêm a estrutura temporal das braçadas direita e esquerda (aspectos invariantes da braçada bem como a coordenação entre os braços inalterada enquanto efetuam ajustes na fase aérea da braçada (aspectos variantes. Assim sendo, atletas jovens de elite apresentam braçada com relativa autonomia frente ao componente respiração e nadam efetuando ajustes considerando a economia de recursos.The aim of this study was to investigate the effects of different breathing patterns on the performance and

    Full Text Available Em solos com elevado grau de intemperismo, a imobilização temporária de fósforo pela biomassa microbiana do solo (BMS pode ser um mecanismo de retardamento das reações de adsorção. O objetivo do presente trabalho foi avaliar a amplitude no fósforo microbiano (Pmem um Argissolo em pastagem nativa submetida à roçada, introdução de forrageiras exóticas e adubadas com fertilizantes fosfatados. O estudo foi desenvolvido a partir de um experimento instalado em 1997 que constava de cinco tratamentos de fosfato e calagem (testemunha semfósforo; hiperfosfato de gafsa; superfosfato triplo; superfosfato triplo + calcário e superfosfato simples + calcário, distribuídos em quatro blocos ao acaso. Em junho de 2002, a pastagem nativaremanescente foi roçada, semeada a pastagem de inverno e as parcelas originais foram divididas em três subparcelas. A reposição dos fertilizantes fosfatados foi feita em três épocas, uma em cadasubparcela: sem reaplicação; reaplicação após a roçada da pastagem nativa remanescente (outonojunho; e reaplicação após a roçada da forrageira hibernal (primavera-novembro.

    2008-03-01

    Full Text Available A busca por materiais alternativos que possam substituir as fibras de amianto, compondo o fibrocimento, tem-se tornado objeto de estudos recorrentes. As fibras vegetais surgem como opção econômica, salubre e ecologicamente adequada. O objetivo desse trabalho foi estudar o comportamento da adição da fibra de curauá em compósitos cimentícios, visando a substituir o amianto. Essa fibra mineral é bastante conhecida pelos danos que provoca à saúde humana, já tendo sido banida em muitos países industrializados. Desde 1979, o Grupo de Pesquisas em Materiais não Convencionais da PUC-Rio tem desenvolvido trabalhos sobre a aplicação das fibras vegetais, disponíveis em abundância no Brasil, na fabricação de componentes para a construção civil, visando, principalmente, à produção de habitação popular. A fibra de curauá é de uso popular, na região conhecida como Baixo-Amazonas, oeste do Estado do Pará, na manufatura de cordas, cestas e tapetes, já existindo os primeiros plantios em escala comercial. Pouco conhecida nas demais regiões do país, a fibra de curauá ainda carece de estudos específicos sobre suas propriedades físicas, químicas e mecânicas, que possibilitem sua aplicação segura em compósitos para a construção civil. Nesse artigo, foi estudado o comportamento em compressão de argamassas reforçadas com fibras de curauá. Buscou-se comparar o desempenho das fibras de curauá e de seus compósitos, com as fibras e compósitos de amianto e de outras fibras vegetais, tais como sisal e juta. Para os compósitos cimentícios com reforços de juta e de sisal, foram obtidos dados através de ensaios realizados no escopo desse trabalho. Os resultados mostraram que a fibra de curauá possui características físicas e mecânicas que a habilitam à aplicação como reforço de matrizes cimentícias, principalmente quando for almejada uma maior ductilidade e uma maior capacidade de resistência após a fissuração da

    , considerando la realidad político económica actual y el sistema de servicios de salud en Portugal.OBJETIVO: este artigo foca o contexto político da implementação de competências avançadas em enfermagem, com ênfase no caso português. O setor da saúde em Portugal, assim como em outros países, usa mão de obra intensa, e a prática de enfermeiros com competências avançadas está atualmente em debate. MÉTODOS: abordagem de métodos mistos com análise de dados internacionais sobre a mão de obra em enfermagem, documentos e notícias na mídia, entrevistas com informantes-chave, questionário online e um workshop técnico com informantes-chave. CONCLUSÕES: existe base de evidência limitada sobre enfermeiros com funções avançadas em Portugal, o que é um entrave ao progresso, mas não uma desculpa para a inércia. Mais estudos conduzidos em Portugal, abordando funções inovadoras para profissionais da saúde, ajudariam a informar e direcionar políticas na área. É necessário avançar para informar, de forma plena, o diálogo político, levando em consideração a realidade atual em termos políticos, econômicos e do sistema de saúde em Portugal.

    Full Text Available Neste relato de caso a radiografia panorâmica é um elemento de importância como auxiliar no diagnóstico terapêutico inicial e depois como suporte no seguimento do caso até o final do tratamento. O caso aqui apresentado é uma abordagem interdisciplinar entre ortodontia e periodontia, em que uma paciente com doença periodontal avançada foi tratada pela técnica de erupção ortodôntica forçada e teve, ao final do tratamento, sua reabilitação conseguida com crescimento ósseo e gengival num primeiro instante e colocação de implantes e próteses dentárias numa abordagem também inovadora de carregamento protético imediato, ou seja, implantes e dentes colocados com 48 horas de diferença. O resultado alcançado aponta que nossos estudos devem prosseguir, visto que o crescimento ósseo foi conseguido sem a necessidade de enxerto, o tempo do tratamento não superou os 120 dias e que no futuro devemos obter resultados que colaborem para a superação de doenças periodontais graves sem varias etapas cirúrgicas, diminuindo o tempo de tratamento, morbidade e custos para o paciente.In this case report we discuss the importance of panoramic x-ray as an auxiliary tool for the diagnosis, initial treatment and follow-up of patients with periodontal disease. The case presented involved an interdisciplinary approach between orthodontics and periodontics. A female patient with advanced periodontal disease was treated with the forced orthodontical eruption technique that resulted in bone and gingival growth at the end of the treatment. Placement of the implants and dental prostheses was also performed in an innovative approach of immediate prosthetic loading, i.e. implants and teeth placed within a 48 hours interval. These results indicate that our studies should continue since bone growth was obtained without a bone graft, the time of the treatment did not exceed 120 days, and that we may in future obtain further results that will contribute to

Essas festas são protagonizadas há várias gerações pela população que habita a baía de Suape, cujo território é disputado pelo Complexo Industrial do Porto de Suape, o que tem provocado graves impactos ambientais sobre a biodiversidade da área com prejuízo das atividades pesqueiras. Como metodologia optou-se pelo estudo etnográfico com uso da observação participante e entrevistas com ênfase na história de vida, combinado com pesquisa bibliográfica e documental. Ainda considerou-se a memória narrativa como composta por “símbolos que demarcam a identidade de um grupo social” (TEDESCO, 2002, explicitando elementos como “relações sociais, seus vínculos de pertencimento, o significado da natureza biofísica nas suas vidas e o conflito socioambiental vivenciado” (SOUZA, 2009.

    Full Text Available OBJETIVO: Desenvolver método de avaliação do estado nutricional do paciente através de escore que expresse o estado nutricional de maneira universal e verificar se esse escore seria eficaz na estratificação prognóstica de pacientes com insuficiência cardíaca (IC avançada. MÉTODOS: Para compor o escore foram selecionados métodos de avaliação que procurassem quantificar forma de medida do estado nutricional: a porcentagem ideal do peso, a espessura da prega tricipital, os percentis da circunferência da massa muscular do braço, os níveis séricos de albumina, a contagem global de linfócitos. Para validá-lo, aplicou-se o escore num grupo de 95 pacientes com idade inferior a 65 anos, sem evidências de doenças consumptivas e analisou-se se esse escore manteria correlação com os dados clínicos da IC e permitiria estratificar o prognóstico. RESULTADOS: A situação nutricional esteve alterada nos pacientes e escore elevado sugerindo desnutrição moderada ou intensa foi observado em 31/95 (32,6% dos casos. Não houve correlação entre os valores do escore nutricional, duração dos sintomas e grau de disfunção ventricular. Os pacientes com escore nutricional elevado apresentaram tendência de maior mortalidade (p=0,0606. CONCLUSÕES: Os dados sugerem que a desnutrição atinge cerca de 1/3 dos pacientes com IC avançada. Um escore que englobou cinco parâmetros de avaliação nutricional teve boa correlação com a avaliação clínica e permitiu avaliar globalmente a desnutrição de portadores de IC. Escore superior a 8 identificou pacientes com maior probabilidade de morrer, confirmando que pacientes mais desnutridos têm pior evolução.OBJECTIVE: Develop a method for the evaluation of patient’s nutritional status through a score that expresses universal nutritional status, as well as investigate if that score would be efficient for the prognostic stratification of advanced heart failure (HF pts.

    Full Text Available Dental amalgam is one of the oldest restorative materials, used in dentistry, which has undergone a lot of quality changes since its advent. Copper is one of the major elements in dental amalgam. Dental amalgam is classified as low and high cooper group based on the percentage of this element. Cinaluy is an Iranian product, a product of Shahid Faghihi's factory and its particles are spherical with high copper and it does not contain any zinc and gama II phase. The goal of this study was to identify the type and percentage of its ingredients and to analyze this dental amalgam by muclear reactor. The products of the factory, at two different times, were compared with each other and also with the percentages presented by the factory, regarding their ingredients. They were also compared with two standardized amalgams called: Sybralloy and Tytin. Three typical Cinalux amalgam capsules, produced on different dates, were selected. The contents of capsules were enveloped in plastic bags and then sealed and placed in a miniature reactor to undergo nuclear radiation for 10 days. After this period, the elements in amalgam became activated and converted into radioisotopes of the same elements, and began to radiate. Then gama spectrometer system accumulated these radiations and transferred them to Span software. This software, aided by reference standards, shows the intensity and the wave length of the received radiation, and consequently identifies the type and percentage of the elements in amalgam. The results demonstrated that the Cinalux amalgam samples, regarding the type and percentage of their elements, were identical and also met the factory standards. The differences were not significant. There was also no significant difference between Cinalux amalgam and the standardized amalgam Sybralloy, regarding the percentage of their elements, but comparing this amalgam with the standardized amalgam Tytin, a significant difference was not observed.

    Kuschill, Jim

    1986-01-01

    In its most basic sense software development involves describing the tasks to be solved, including the given objects and the operations to be performed on those objects. Unfortunately, the way people describe objects and operations usually bears little resemblance to source code in most contemporary computer languages. There are two ways around this problem. One is to allow users to describe what they want the computer to do in everyday, typically imprecise English. The PRODOC methodology and software development environment is based on a second more flexible and possibly even easier to use approach. Rather than hiding program structure, PRODOC represents such structure graphically using visual programming techniques. In addition, the program terminology used in PRODOC may be customized so as to match the way human experts in any given application area naturally describe the relevant data and operations. The PRODOC methodology is described in detail.

MATERIAIS E MÉTODOS: A amostra utilizada foi constituída pelo dueto (24 ± 0 anos representante do Brasil em Atenas 2004. A coleta de dados foi realizada durante uma sessão de treinamento com duração de 198 minutos. O treino se iniciou com a parte física, seguida da parte técnica. Para a determinação da glicemia e da concentração de beta-hidroxibutirato foi utilizado o monitor Optium® com suas respectivas tiras. As concentrações de cortisol e das enzimas lactato desidrogenase (LDH e creatina quinase (CK foram determinadas por radioimunoensaio (DPC© e kits comerciais (CELM®, respectivamente. O acompanhamento da freqüência cardíaca (FC foi realizado com o freqüêncimetro Advantage Polar®. RESULTADOS: Foi observada redução (~2% do peso corporal. A glicemia também apresentou queda (~30% em comparação ao valor obtido no início do treino. Em contrapartida, foi observada elevação na concentração de cortisol (salivar 22% e plasmática 29% e de beta-hidroxibutirato (~340%. Não foi observada alteração significativa na concentração plasmática de CK e de LDH. O acompanhamento da FC demonstrou que dos 198 minutos que constituíram a sessão de treino, 36,5 ± 0,7 minutos foram realizados em intensidade leve; 103,5 ± 0,7 minutos em intensidade moderada, 54,0 ± 2,1 minutos em intensidade alta e 4,0 ± 0,0 minutos em intensidade muito alta. CONCLUSÕES: A perda de peso indica que a reposição hídrica não foi adequada. A redução na glicemia e o aumento na concentração de corpos cetônicos e de cortisol reforçam a importância da suplementação de carboidrato durante o treino de longa duração. O comportamento da FC demonstra que a sessão de treinamento foi realizada em uma intensidade moderada, porém com

    Full Text Available The virulence pattern of the isolates of Pyricularia grisea from commercial fields of the upland rice (Oryza sativa cultivars 'Primavera' and 'BRS Bonança' was analyzed. A hundred and seventy monoconidial isolates of the pathogen virulent to 'Primavera' and 139 to 'BRS Bonança' collected from eight fields, during two years (2001-2003 were tested, under greenhouse conditions, on six newly released rice cultivars. Differences in virulence pattern were observed in pathogenic populations of 'Primavera' and 'BRS Bonança'. Isolates with virulence to improved cultivars were common in samples from farmers' fields in the absence of aloinfection. The virulence frequency of P. grisea isolates collected from 'Primavera'' to cultivars 'BRS Vencedora', 'BRS Colosso', 'BRS Liderança', 'BRS Soberana', 'BRS Curinga' and 'BRS Talento', was high in descending order. On the other hand, in the fungus population of 'BRS BRS Bonança' virulence frequency was high in 'BRS Talento', followed by 'BRS Curinga', 'BRS Vencedora', 'BRS Liderança', 'BRS Colosso' and 'BRS Soberana'. While virulence to 'BRS Talento' was rare among isolates from 'Primavera', it was most frequent in isolates of 'BRS Bonança'. The six improved rice cultivars permitted to differentiating agriculturally important virulences in the pathogen population which can be utilized in selecting breeding lines for specific resistance, in rice blast improvement program.Foi analisado o padrão de virulência de isolados de Pyricularia grisea provenientes de lavouras de arroz (Oryza sativa de terras altas das cultivares 'Primavera' e 'BRS Bonança'.

    Full Text Available Para garantir a qualidade das informações disponibilizadas pelas empresas brasileiras, o legislador e os órgãos de regulamentação têm empreendido esforços no sentido de definir as informações que devem ser apresentadas nas demonstrações contábeis. Entretanto, nem todas as orientações têm caráter de obrigatoriedade, tornando-se mais uma questão de ética e responsabilidade corporativa. O presente estudo procura responder à seguinte questão de pesquisa: Qual o grau de observância às orientações sobre evidenciação contábil praticado pelas sociedades anônimas brasileiras no tocante à prestação de informações não contempladas nas demonstrações contábeis tradicionais, consideradas de natureza avançada e não obrigatória? O estudo analisou as demonstrações contábeis de 95 empresas, relativas ao exercício social encerrado em 31/12/2002, com a utilização do método de "análise de conteúdo". Utilizou-se o software Statistical Package for Social Sciences - SPSS para apoio na tabulação e análise dos dados. De um total de 21 itens de evidenciação investigados, apenas seis apresentaram um índice de observância superior a 50%, o que demonstra que as organizações ainda têm um longo caminho a percorrer na busca da transparência e qualidade na divulgação das informações contábeis.In order to ensure the quality of information issued by Brazilian enterprises, legislators and regulatory agencies are making efforts to determine the set of information that should appear in the financial statements.

    The motivation and causes of economic growth in China are analyzed in detail by applying AD-AS model, which finds that there are two kinds of motivations and causes of aggregate demand and aggregate supply that maintain long-term rapid economic growth in China. From aspect of demand, the growth of investment, government procurement expenditure, net export and money supply improve the level of aggregate demand, which pulls economic growth. From aspect of supply, the increase of population and the improvement of population quality are necessary basic conditions of increasing aggregate supply; the transfer of labour force from the primary industry to the secondary and the tertiary industries does not reduce the output of the primary industry, however, it improves the production capacity of the secondary and the tertiary industries greatly; the development of technological level improves the marginal output capacity of factors and perfects the production function; and the continuous deepening economic reform releases huge economic vitality and arouses infinite potential of production. These factors compose the resultant force of increasing effective supply together, which promotes economic growth. Supply factor is the characteristic factor of maintaining long-term rapid economic growth in China, and it is the special factor distinguished from many developed countries. Conclusion is drawn at last that it is completely possible for China to maintain rapid economic growth for a longer period of time in the future.%运用AD-AS模型对中国经济增长的动因进行详细分析,发现中国经济长期保持快速增长有来自总需求和总供给两方面的动因。在需求方面,投资增长、政府购买支出增长、净出口增长和货币供应量的不断增加提高了总需求水平,从而拉动了经济增长。在供给方面,人口数量的增加和人口质量的提高是增加总供给的必要基础条件;劳动力从一次产业向二次、三次

MÉTODOS: Realizou-se espirometria forçada, de acordo com as normas da Sociedade Brasileira de Pneumologia e Tisiologia, em 643 adultos brancos não-fumantes. Os valores previstos obtidos por pesquisadores brasileiros em 1992 e os obtidos por quatro grupos de pesquisadores estrangeiros foram comparados com os novos valores previstos brasileiros obtidos em 2006. Em uma segunda fase, os valores médios obtidos em 65 mulheres e 79 homens adultos foram comparados aos valores previstos obtidos pelas diversas equações de referência. RESULTADOS: O teste t para amostras pareadas revelou diferenças significativas entre os valores previstos obtidos pelas seis equações e os obtidos pela equação brasileira de 2006. Na segunda fase, observou-se que os valores previstos obtidos por Crapo et al. e os obtidos por Hankinson et al. para os méxico-americanos mostraram valores médios semelhantes aos observados na nova amostra. Porém, quando os valores previstos obtidos na nova amostra foram comparados com os obtidos por esses autores, discrepâncias foram observadas, com valores previstos altos e baixos. Os valores obtidos pela equação brasileira de 2006 mostraram as menores diferenças em comparação com os valores médios obtidos na nova amostra. CONCLUSÕES: Estes resultados sublinham a importância de se usar equações de predição para espirometria que sejam apropriadas para nossa população.OBJECTIVE: To compare the most recent (2006 predicted values of forced vital capacity and forced expiratory volume in one second for spirometry in Brazilians with those obtained using other reference equations and to validate the findings

    Full Text Available Os materiais cerâmicos têm muitas vantagens em relação a outros materiais, entre elas, três principais: capacidade de operação em altas temperaturas, alta dureza e alta resistência ao desgaste. Por essa razão, são aptos a serem usados em situações que exigem pouco desgaste, tanto em temperatura ambiente quanto em temperaturas elevadas. Estas propriedades fizeram as cerâmicas avançadas terem uma importante parte na utilização em aplicações na indústria nas últimas décadas. Porém, o custo agregado ao acabamento da peça ainda é muito alto. Esse acabamento geralmente é feito pelo processo de retificação, único processo economicamente viável que produz superfícies de elevada qualidade e precisão geométrica. As empresas desse modo vêm buscando a otimização no processo de retificação de cerâmicas, explorando outras técnicas de lubrificação. Assim, este projeto pretendeu explorar a otimização do método de lubrificação na retificação cilíndrica externa de mergulho com o método da mínima quantidade de lubrificação (MQL e refrigeração otimizada. Foram utilizadas três métodos de refrigeração, o convencional o MQL e a refrigeração otimizada, com três avanços de corte para cada caso. Foram analisadas como variáveis de saída a relação G, rugosidade e circularidade. Dos resultados obtidos, pode-se concluir que a refrigeração otimizada é a que apresenta os melhores resultados, sendo esta uma alternativa viável de melhora do processo. O MQL apresentou resultados insatisfatórios em comparação aos outros dois métodos, porém, ainda aceitáveis em alguns processos de retificação. Considerando a dificuldade e altos custos de descarte do fluido de corte devido às rígidas leis ambientais, o MQL vem como uma forte tendência neste tipo de processo.Ceramic materials have many advantages over other materials, including three main: capability of operating at high temperatures, high hardness and

    Full Text Available Diversas metodologias têm sido desenvolvidas para investigar a qualidade e as principais queixas e distúrbios relacionados ao sono. Uma forma conhecida de investigar as características temporais dos organismos é a cronobiologia, ciência divide a população em três cronotipos básicos para avaliar as diferenças individuais na prevalência pelos horários de vigília e de sono: os matutinos, os vespertinos e os indiferentes. Outro ponto importante, é que existem poucos estudos relacionando o padrão do sono em indivíduos com necessidades especiais e a atividade física. O sono é considerado como restaurador e o exercício está associado diversas alterações no padrão de sono. A maioria dos estudos referente ao feito do exercício sobre o sono podem ser abordados ou correlacionados com a teoria de restauração das funções do sono. O objetivo deste estudo foi o de avaliar o padrão, queixas relativas ao sono, cronotipo e adaptação ao fuso horário de Sidney dos atletas brasileiros que disputaram a paraolimpíada em 2000. Participaram da avaliação 64 atletas paraolímpicos, com idades de 26,3 (± 5,9. Todos os atletas responderam aos questionários de padrão e queixas relativas ao sono e cronotipo, passando também por uma adaptação ao fuso horário de Sidney. Oprocesso de sincronização ao fuso horário foi realizado de forma abrupta, na tentativa de romper com o ciclo claro-escuro que estava relacionado ao horário brasileiro. Os resultados demonstram que 34,4% dos atletas apresentavam uma insatisfação com o seu próprio sono, sendo que os distúrbios de sono mais relatados foram: apnéia (14%, refluxo gástrico (15,6%, dor de cabeça (14,1%, ansiedade pós-pesadelo (39,1%, caimbras (20,3%, sonilóquio (26,6%, pânico noturno (9,4%, PLM (9,4% e bruxismo (9,4%.

    Full Text Available El derrumbe financiero y económico que se inició en 2007 en Estados Unidos después de la conocida como crisis de las hipotecas subprime se tornó global un año después. En España, uno de los países más afectados por la larga crisis, la prosperidad anterior enseguida pareció ser un espejismo. Pero la crisis no ha afectado a todo el mundo en la misma medida. De hecho, hay gente que se ha enriquecido durante el período 2008-2012, en cambio, la crisis está teniendo un impacto mayor sobre los que ya se encontraba en una situación más precaria. En este artículo discutiré una de las múltiples caras de la crisis española que está afectando a los más desaventajados: los desahucios y su resistencia por parte de la población migrante. Para hacer esto, primero examinaré un municipio que ha sido paradigmático de enclave migrante en España: Salt. Salt es un municipio conocido en Girona, Catalunya, por haber sido descrito en los medios de comunicación como un gueto como resultado de los problemas que surgen con el exceso de inmigración (el 42% de su población es de origen extranjero. Salt se hizo famoso cuando en marzo de 2010 un grupo de vecinos entró en el ayuntamiento exigiendo más seguridad y denunciando la pasividad de la policía ante una ola de robos en el pueblo. Desde entonces, distinto conflictos aparecen en los medios de comunicación. De todos modos, una etnografía desde una perspectiva criminológica muestra que el problema que aparece en los medios de comunicación (el delito callejero es solo uno entre los varios que afectan a la población. Peor aún, toda la atención puesta sobre el municipio por medios, políticos y policías no ha servido para la detección de un problema que está generando mucho más daño social: los desahucios. La crisis ha servido para observar el modus operandi de bancos y agencias inmobiliarias, los principales victimarios en el conflicto de los desahucios. Vendían pisos, nunca los alquilaban, usando todo tipo de estrategias y trucos, con la intención de maximizar los beneficios, aun sabiendo que cometían ilegalidades. No obstante, quedó claro que eran prácticas que violaban sistemáticamente el derecho a la vivienda y a la ciudad. Entonces, en Salt podemos ver, la reproducción de un problema anterior: una fuerte presión de la policía en la ciudad, por un lado, mientras se produce una fuerte estigmatización de los más desaventajados por otro. Al mismo tiempo, los crímenes de los poderosos son absolutamente ignorados aunque produzcan más daño social.

  16. Americans with Disabilities Act: physician-shareholder practice groups and ADA compliance.

    Odem, Nathan; Blanck, Peter

    2003-02-01

    This article examines the application of Americans with Disabilities Act requirements to professional associations like physician practice groups. In general, employers with 15 or more full-time employees must comply with the Act. However, the definition of an employee is sometimes unclear, especially as applied to business entities commonly used by physician practice groups. A recent case decided by the United States Court of Appeals for the Ninth Circuit held that physician-shareholders of a professional corporation are employees for Americans with Disabilities Act coverage purposes. Analogous cases in other federal circuits have held differently, likening the "owners" of professional corporations to partners in a partnership, who are not considered employees. Similar questions arise for popular business entities, such as Limited Liability Companies and Limited Liability Partnerships. This article discusses the nature of the business forms commonly used by physician practice groups and how their characteristics impact employee status for Americans with Disabilities Act coverage. It then suggests that examination is useful beyond business formation characteristics to the purpose of the Americans with Disabilities Act and other employment antidiscrimination statutes.

    There are several reasons that made us develop a work upon two chosen epic poems, one from a Latin poet of the 1st century B.C., the other one from a poet of the New World in the 19th century. On one hand, we noticed the exceptional influence of Virgil on the epic structure of the Timbiras, even if Gonçalves Dias himself called to his poem, at the beginning, the Brazilian Iliad; hence why the title of this research reminds us of Homer’s poem. Both poems appeared in the same way and with the s...

  18. The circadian regulation of sleep: impact of a functional ADA-polymorphism and its association to working memory improvements.

    Carolin F Reichert

    Full Text Available Sleep is regulated in a time-of-day dependent manner and profits working memory. However, the impact of the circadian timing system as well as contributions of specific sleep properties to this beneficial effect remains largely unexplored. Moreover, it is unclear to which extent inter-individual differences in sleep-wake regulation depend on circadian phase and modulate the association between sleep and working memory. Here, sleep electroencephalography (EEG was recorded during a 40-h multiple nap protocol, and working memory performance was assessed by the n-back task 10 times before and after each scheduled nap sleep episode. Twenty-four participants were genotyped regarding a functional polymorphism in adenosine deaminase (rs73598374, 12 G/A-, 12 G/G-allele carriers, previously associated with differences in sleep-wake regulation. Our results indicate that genotype-driven differences in sleep depend on circadian phase: heterozygous participants were awake longer and slept less at the end of the biological day, while they exhibited longer non rapid eye movement (NREM sleep and slow wave sleep concomitant with reduced power between 8-16 Hz at the end of the biological night. Slow wave sleep and NREM sleep delta EEG activity covaried positively with overall working memory performance, independent of circadian phase and genotype. Moreover, REM sleep duration benefitted working memory particularly when occurring in the early morning hours and specifically in heterozygous individuals. Even though based on a small sample size and thus requiring replication, our results suggest genotype-dependent differences in circadian sleep regulation. They further indicate that REM sleep, being under strong circadian control, boosts working memory performance according to genotype in a time-of-day dependent manner. Finally, our data provide first evidence that slow wave sleep and NREM sleep delta activity, majorly regulated by sleep homeostatic mechanisms, is linked to working memory independent of the timing of the sleep episode within the 24-h cycle.

    Full Text Available We present a curious heavy specimen whose novelty resides, besides the piece itself, in the two noticeable pellets behind the galley prow on obverse. These pellets, conceived as a mark of value, could belong to the original obverse die or, in this case, to an earlier coin struck over; but, admittedly, there is still another possibility that we rule out in this paper: a new value to add, like an “As” or “Unit” for the then Gaditan mint of Carissa.

  4. Mercury contamination - Amalgamate (contract with NFS and ADA). Stabilize Elemental Mercury Wastes. Mixed Waste Focus Area. OST Reference Number 1675

    None, None

    1999-09-01

    Through efforts led by the Mixed Waste Focus Area (MWFA) and its Mercury Working Group (HgWG), the inventory of bulk elemental mercury contaminated with radionuclides stored at various U. S. Department of Energy (DOE) sites is thought to be approximately 16 m3 (Conley et al. 1998). At least 19 different DOE sites have this type of mixed low-level waste in their storage facilities. The U. S. Environmental Protection Agency (EPA) specifies amalgamation as the treatment method for radioactively contaminated elemental mercury. Although the chemistry of amalgamation is well known, the practical engineering of a sizable amalgamation process has not been tested (Tyson 1993). To eliminate the existing DOE inventory in a reasonable timeframe, scaleable equipment is needed that can: produce waste forms that meet the EPA definition of amalgamation, produce waste forms that pass the EPA Toxicity Characteristic Leaching Procedure (TCLP) limit of 0.20 mg/L, limit mercury vapor concentrations during processing to below the Occupational Safety and Health Administration’s (OSHA) 8-hour worker exposure limit (50 mg/m3) for mercury, and perform the above economically.

  16. Poliolefinas reforçadas com fibras vegetais curtas: sisal × curauá Polyolefins reinforced with short vegetal fibers: sisal vs. curauá

    Márcia A. S. Spinacé

    2011-01-01

    Full Text Available É crescente o interesse nos compósitos poliméricos reforçados com fibras vegetais curtas em substituição às fibras de vidro, pois as fibras naturais provêm de fontes renováveis, não são abrasivas aos equipamentos de processamento, são biodegradáveis, e possuem baixa densidade comparada às fibras de vidro. Elas apresentam início de degradação em torno de 200 °C, sendo adequadas para reforçar poliolefinas que são processadas até essa temperatura ou termofíxos. Várias fibras vegetais vêm sendo usadas como reforço, dentre elas o curauá e o sisal; no entanto, há grande controvérsia na literatura sobre as propriedades finais dos compósitos. Neste trabalho comparamos as propriedades de compósitos de polietileno de alta densidade ou polipropileno com 20% em massa de fibras curtas de sisal ou de curauá com ou sem agentes de acoplagem. Todos foram processados por extrusão e moldados por injeção, exatamente nas mesmas condições, e os resultados foram comparados em termos das propriedades mecânicas. As fibras de curauá apresentam resistência à tração superior às fibras de sisal e os compósitos com fibras de curauá apresentaram resistência à tração e flexão ligeiramente superior aos compósitos com fibra de sisal. No caso da resistência ao impacto a situação se inverte. Como o sisal é mais frágil que o curauá, durante o processamento ocorre maior quebra da fibra provocando essa diferenciação nas propriedades mecânicas dos compósitos.There is growing interest in reinforced polymer composites using short vegetal fibers to replace glass fibers for several reasons. The composite fibers are produced from renewable resources, being biodegradable and less abrasive to the processing equipment, in addition to possessing a lower density than the glass fibers. Since their thermal degradation onset is at 200 °C, they can be used to reinforce thermoplastics processed below this temperature and thermosets. Several vegetal fibers have been used as reinforcing agent, including sisal and cuaruá. However, there is controversy in the literature about the composites final properties. In this work we compare the properties of composites of high density polyethylene or polypropylene with 20 wt. (% of short sisal or curauá fibers, with or without a coupling agent. All composites were processed by extrusion and molded by injection, under exactly the same conditions, and the mechanical properties were compared. The curauá fibers presented a higher tensile resistance than the sisal fibers, and the composites with curauá fibers had slightly higher tensile and flexural resistance compared to the sisal fiber composites. The situation is opposite in the impact resistance results, with sisal composites displaying higher impact resistance. Since sisal fibers are more fragile than curauá fibers, during processing there is a higher fracture of sisal in comparison to curauá, inducing these differences in composites mechanical properties.

  18. Una aproximación analítica a las mallas recíprocas diseñadas por Leonardo

    Sánchez, J.

    2010-06-01

    Full Text Available It is a topic to refer Leonardo when we introduce any branch of the art, science o technique because his manuscripts ever contain news that before him never where explored, nor profited even later. This can be understood because these manuscripts never where published till five centuries later. Observations referred to design of structures are the less known and otherwise the less studied. Really the most important problems about this subject are contained in the Codex I of Madrid, some in the Codex Atlantic, and less in the Codex II of Madrid. Other books do not refer these questions. Leonardo, in his drawings, manifested an obsessive search for solutions to the problem of how to span great distances with short pieces. In his notebooks, we find reiterative diagrams which seem to be searching for variants of frames capable of constituting structures, mainly roofs, floors and bridges, which could cover large distances by using manageable pieces that could easily be supplied. In this paper we analyze with actual computer programs how his proposals could be achieved and we establish some conclusions about it.

    Ya resulta tópico referirse a Leonardo cada vez que tocamos algún tema de arte, ciencia o técnica puesto que en sus escritos siempre podemos encontrar aspectos que nadie estudió antes ni, en muchos casos, nadie explotó después. Esto se explica porque sus manuscritos no fueron publicados hasta cinco siglos después. Sus observaciones respecto al diseño de estructuras son menos conocidas y son también las menos estudiadas. Realmente sus principales aportaciones se contienen en el Códice I de Madrid, y menos en el Códice II de Madrid, algunas otras, más generales, en el Códice Atlántico. Sus otros cuadernos de notas no tratan de estas cuestiones. En sus dibujos, Leonardo manifestó una obsesiva búsqueda de soluciones para cubrir grandes luces con piezas cortas. En sus Cuadernos encontramos diagramas de muchas variantes para construir cubiertas, forjados y puentes que pudieran salvar grandes luces con piezas manejables y disponibles. En este artículo se analizan con los actuales programas de cálculo cómo funcionan sus propuestas y establecemos algunas conclusiones.

    2010-12-01

    Full Text Available O programa de melhoramento genético da Embrapa Clima Temperado enfatiza a criação de cultivares de maturação precoce, produtoras de frutas de polpa não fundente. Isto é devido ao interesse dos produtores e da indústria conserveira, uma vez que tais cultivares têm mais baixo custo de produção e muito boa oportunidade de mercado. A cv. BRS Libra atende a esta demanda e já foi testada por produtores da área próxima a Pelotas, por vários ciclos, contando com a cooperação do serviço de Extensão do Rio Grande do Sul. Mais recentemente, os testes foram estendidos a outras regiões com a parceria de instituições de pesquisa públicas e privadas. A cv. BRS Libra tem baixa necessidade em frio, com floração precoce e maturação iniciando geralmente, no início de outubro e ocasionalmente, ao final de setembro, no município de Pelotas. A sua exigência em frio não foi determinada precisamente, mas por comparação com outras cultivares estima-se que seja entre 100 e 200 horas.The Embrapa peach breeding program emphasizes the development of early ripening cultivars which produce non-melting flesh peaches. This is due to the interest of growers and canning industry on these cultivars because of the lower production costs plus the market oportunities. The BRS Libra cv. meet this objective and has been tested by growers around Pelotas'area, for several years with the collaboration of the extension service of Rio Grande do Sul State, and more recently in other areas, thanks to the cooperation of other public and private research institutions. It has low chilling requirement, early blooming and the harvest generally starts by beginning of October and exceptionally end of September, in Pelotas, RS. The chilling requirement was mot precisely determined but by comparison with other cultivars, it is estimated between 100 and 200 hours.

Para tanto, é desenvolvido um apanhado histórico dos economistas clássicos que incorporaram essa noção, avaliando criticamente o seu uso. A partir do materialismo histórico, observamos uma aplicação mais consistente da noção de mobilidade, a idéia de “mobilidade forçada”, que foi desenvolvida a mais de vinte anos por Jean Paul de Gaudemar e que centra sua análise no conceito de valor/trabalho, desenvolvido por Marx. Essa abordagem traz uma importante contribuição teórica para os estudos em geografia da população.The aim of this article is to investigate the work-centered mobility notion. Therefore a historical survey of the classic economists who incorporated this concept was carried out and its use critically evaluated. Starting from the historical materialism, a more consistent application of the notion of mobility. The idea of forced mobility established twenty years ago by Jean Paul de Gaudemar and centered on Marx’s value/work concept, has been observed, which has trough an important theoretical contribution to the studies of population geography.

    The Mercosul (Southern Common Market) has always faced difficulties, arising from two main factors, the absence of solidarity among its Member States and the political/economic volatility of those States. The path to European integration hasn't also been exempt from obstacles; and it was recently sought to solve fundamental problems of European integration by means of the juridical instrument called enhanced cooperation. Hence, a natural question: could enhanced cooperation be an adequate exp...

    Full Text Available La nueva globalización comercial modificó el mapa de la industria mundial. El mundo de hoy es diferente del de ayer. El Norte ya no domina al Sur de la misma manera. En el Sur hay grandes heterogeneidades entre los países más atrasados, los emergentes asiáticos y latinoamericanos, etc. Algunos países del Sur han llegado a imponer sus propias reglas de juego. Pero no todas las economías emergentes del Sur tienen la misma capacidad para imponerse, como las de América Latina. Estas se benefician temporalmente del alto crecimiento de Asia, pero experimentan un proceso de desindustrialización que las debilita. Algunas teorías y herramientas analíticas se han vuelto obsoletas o erróneas, como el enfoque centro-periferia. Países que ayer pertenecían a la periferia, han adquirido características del antiguo centro e incluso ejercen control sobre países desarrollados.

  9. Roma y los sistemas monetarios provinciales. Monedas romanas acuñadas en Hispania en la segunda guerra púnica

    2009-12-01

    Full Text Available RESUMEN: Se señala la libertad económica que la Roma republicana concedió a las provincias para la acuñación de moneda local y para la utilización de los sistema ponderales propios. En el caso de Hispania todos los valores acuñados bajo Roma proceden de patrones indígenas, incluido el mal llamado "denario ibérico". Por su parte, los generales romanos gozan de la misma libertad de acuñación respecto a su sistema monetario y se aprovechan de los factores económicos más rentables en las provincias; de ello son testimonio todos los valores anómalos de plata acuñados por Roma en Hispania que ya conocíamos y las nuevas monedas que publicamos aquí: una dracma del Juramento y los ases y semises de plata, las libellae y simbellae citadas por Varrón.ABSTRACT. We point out the economic freedom that Rome allowed the provinces in regard to the monetary sistems. In Hispania all the values minted in the Republican times are inscribed in the indigenous metrological standards, included the wrongly called "denario ibérico". On their side the Roman generals enjoyed the same freedom for minting any value in any metal in the provinces in regard to profit the special economic characteristic of the land. That is proved by all the anomalous silver denominations minted by the Romans in Spain, some of them newly discovered: a drachme of the Oath-taking scene and the silver ases and semises, the libellae and simbellae quoted by Varron.

  11. Esclerosis lateral amiotrófica: ¿es el astrocito la célula primariamente dañada?

    Roberto E. Sica

    2013-12-01

    Full Text Available La esclerosis lateral amiotrófica (ELA es considerada una enfermedad primaria de las motoneuronas. Ninguno de los procesos que conforman su patogenia ha probado ser su causa. Tampoco pudo demostrarse que factores ambientales la originen. Las neuronas mueren por apoptosis, hecho que abre la posibilidad de que ello sea debido a cambios en su ambiente, sin que constituyan el blanco directo de la noxa que ocasiona la enfermedad. El examen del medio que circunda a las motoneuronas encuentra a los astrocitos como responsables de su bienestar. Éstos son células plásticas, adaptan su función al tipo de neurona con la que se relacionan, cada población astrocitaria es única; si fuera afectada, las neuronas que le son dependientes padecerían. En el caso de las motoneuronas, esta circunstancia llevaría a la alteración de la producción astrocitaria de neurotransmisores y transportadores y a la carencia de nutrientes y factores tróficos que le suministran. Para explicar por qué en la ELA los síntomas se trasladan de un grupo muscular al vecino, observación correlacionada con lo que ocurre en las neuronas motoras corticales y espinales, la hipótesis aquí sostenida sugiere que el factor causante migra de un astrocito a otro, lesionándolos y privando a las motoneuronas del cuidado que le prodigan. También propone que una proteína del astrocito se pliega defectuosamente, transformándose en infecciosa e induciendo el plegamiento errado de sus similares normales, trasladándose entre los astrocitos protoplásmicos y a los astrocitos fibrosos que rodean la vía piramidal, utilizando para ello las sinapsis de hendidura.

  14. Mercury Contamination - Amalgamate (contract with NFS and ADA). Demonstration of DeHgSM Process. Mixed Waste Focus Area. OST Reference Number 1675

    None, None

    1999-09-01

    Through efforts led by the Mixed Waste Focus Area (MWFA) and its Mercury Working Group (HgWG), the inventory of bulk elemental mercury contaminated with radionuclides stored at various U.S. Department of Energy (DOE) sites is thought to be approximately 16 m3 (Conley et al. 1998). At least 19 different DOE sites have this type of mixed low-level waste in their storage facilities. The U.S. Environmental Protection Agency (EPA) specifies amalgamation as the treatment method for radioactively contaminated elemental mercury. Although the chemistry of amalgamation is well known, the practical engineering of a sizable amalgamation process has not been tested (Tyson 1993). To eliminate the existing DOE inventory in a reasonable timeframe, scalable equipment is needed that can produce waste forms that meet the EPA definition of amalgamation, produce waste forms that pass the EPA Toxicity Characteristic Leaching Procedure (TCLP) limit of 0.20 mg/L, limit mercury vapor concentrations during processing to below the Occupational Safety and Health Administration’s (OSHA) 8-h worker exposure limit (50 mg/m3) for mercury, and perform the above economically.

No obstante, aun persisten muchos mitos, temores y opiniones que imposibilitan desarrollar mejor esta triada para la generación de nuevos ambienteseducativos capaces de preparar realmente para ser sujetos actores en un mundo globalizado.Para mejorar estas relaciones, uno de los caminos posibles de reflexión puede ser pensar la tecnología, la comunicación y la educación, no como conceptos por fuera de lo humano, sino por el contrario, como aquello que lo constituye. Pensar así es poder hacerle preguntas al presente en torno a esta relación, y desplazarse por el pasado para encontrar en sus insurgencias, continuidades, rupturas ydiscontinuidades. En fin, poder ir al pasado para recordar o, más importante aun, para olvidar, para saber que somos distintos, que pese a conservar esos elementos inmanentes a lo humano, nuestra contemporaneidad funda relaciones inéditas con la tecnología, la comunicación y la educación./Nowadays the increasing of communication and information Technologies produce, help to produce or validate substantial changes in world wide culture, they must be thinking systematically to not to simply negate them or to point them as harmful or validate them as needed, without an understanding of its real nature.Three elements of the contemporary world are distinguished as potencies to face the challenges of the XXI century: technology, communication and education, the three, inextricable related, are part of the worries of the power - know this days. Although, there are, still, too much myths, fears and opinions that makes difficult to develop this triad to generate new educative environments that are able to prepare subjects to be really actors in a globalize world.To get better this relation, one of the possible reflection paths could be to think the technology, the communication and the education, no as concepts outside the human being, but in the contrary, like something that constitute him. Thinking in that way, makes possible to ask questions to the present about their relations, and go on a flashback to find in their insurgencies, continuities, breaking-off and discontinuities. Anyway, to be able to go to the past to remember, or still more important, to forget, in order to know that we are different, that even though we still get those elements inherent to the human being, our contemporary funds unknown relations with technology, communication and education.

A análise convencional, por coloração, revelou um comportamento relativamente normal, durante a microsporogênese, para a maioria das linhagens, com índice meiótico (IM e percentual médio de viabilidade polínica acima de 90%. As principais anormalidades observadas foram aderências cromossômicas, cromossomos não orientados, retardatários, pontes, micronúcleos, micrócitos e citomixia. Três linhagens, CNPH 0283, CNPH 3000 e CNPH 3773 mostraram menor percentual de pólens viáveis, respectivamente 77, 66 e 58%. Somente para CNPH 0283 a baixa fertilidade do pólen esteve associada à maior frequência de irregularidades e, consequentemente, ao baixo IM (77%. Os resultados do presente trabalho confirmam a importância da análise citológica como ferramenta auxiliar na seleção de linhagens meioticamente estáveis e potencialmente férteis o que possibilita o planejamento de programas de produção de sementes das cultivares em vias de lançamento.Twelve lines of pepper, from different groups {Jalapeño (CNPH 2862, CNPH 2864, Dedo-de-Moça (CNPH 1397, CNPH 0039, CNPH 0053, Cambuci (CNPH 0283, Peixe-Boi (CNPH 0434, Falsa Cumari (CNPH 3761, Bode Vermelha (CNPH 3773, Biquinho Doce (CNPH 3870, Tabasco (CNPH 3000 and Malagueta (CNPH 2869 had their meiotic behavior and the estimation of pollen viability analyzed with the aim of indicating potentially fertile material for the Capsicum breeding program. Conventional analysis by staining revealed a slightly irregular behavior during microsporogenesis for the majority of lines: the meiotic index (MI and pollen viability were over 90%, therefore considered meiotically stable. The main abnormalities observed were chromosome stickiness, unoriented chromosomes, laggards, bridges, micronuclei, microcytes and cytomixis. Three lines (CNPH 0283, CNPH 3000 and CNPH 3773 showed lower pollen viability, 77, 66 and 58% respectively. The lower pollen viability in CNPH 0283 was associated with higher frequency of irregularities and consequently the low MI (77%.

    Full Text Available Political and current events effect society causing changes and transformations in social awareness. To this end, all kinds of changes and transformations reflect on art which is the mirror of society. Cinema which is the seventh form of art is also effected in time either as development or regression. Therefore, the effects of globalization that commenced after the 2nd World War has also reflected on cinema. The reflections of anxiety in mankind that occurred after the atom bomb was dropped on Japan have first materialized with the increase of doomsday related movies. This type of horror cinema defined by movie critic Charles Derry as doomsday movies generally involves mutated creatures such as fish, birds or humans. The appearance of doomsday related movies depends on social anxieties. Zombie movies which have appeared due to social anxieties and spread in the context of globalization can be seen in almost all countries. Even though the Haiti based zombie concept was present prior to the 2nd World War, it transformed into a different concept after the atom bomb was dropped due to the nuclear and radiactive threats and its cinematic representation has thus evolved. Today, when all concepts and movements roam freely from country to country in the context of globalization, the zombie concept has entered our cinema with the movie “The Zombie Wedding” (2010, Directed by: Murat Emir Eren, Talip Ertürk. In this study, first the concept of zombies will be defined and the cliches of zombie horror movies will be mentioned. Afterwords the first Turkish zombie movie “The Zombie Wedding” will be analyzed by making use of critical and semiotic theories and its indicators spesicif to the Turkish society will be emphasized.

As imagens de microscopia eletrônica de varredura (MEV das superfícies fraturadas demonstraram que os compósitos apresentaram boa interface reforço/matriz, consequência da elevada área superficial da CM e presença de grupos polares (hidroxilas tanto na matriz como na celulose, o que permitiu a formação de ligações hidrogênio, favorecendo a compatibilidade entre ambas. A análise térmica dinâmico-mecânica (DMTA demonstrou que todos os compósitos apresentaram elevado módulo de armazenamento à temperatura ambiente. Além disso, o compósito reforçado com 30% de CM apresentou baixa absorção de água, comparável à do termorrígido fenólico, que é utilizado em escala industrial. Os resultados demonstraram que compósitos com boas propriedades podem ser preparados usando elevada proporção de materiais obtidos de biomassa.Glyoxal, which can be obtained from biomass (as by lipids oxidation, is non-toxic and non-volatile. It was used as a substitute of formaldehyde, which does not have these properties, in the synthesis of a novolac-type phenolic resin, using oxalic acid as a catalyst, which can also be obtained from renewable sources. The glyoxal-phenol resin was used in the preparation of composites reinforced with microcrystalline cellulose (MCC 30, 50, and 70% w/w. Scanning electron microscopy (SEM images of the fractured surfaces showed that the composites presented a good reinforcement/matrix interface. This can be attributed to the high surface area of the MCC and also to the presence of polar groups (hydroxyl in both cellulose and matrix, which allowed the formation of hydrogen bonds, leading to a good adhesion between the components present at the interface. Dynamic mechanical thermoanalysis (DMTA showed that all of the obtained composites have high storage modulus at room temperature. Moreover, the composite reinforced with 30% of MCC showed the lowest water absorption, almost the same as that of the phenolic thermoset, which is used in industrial applications. The results showed that composites with good properties can be prepared using high proportions of materials obtained from biomass.

    Full Text Available Osman Turan entered politics as the parliamentarian of Trabzonfrom Democrat Party after the elections held on 2nd of May 1954. Hecontinued his service until 1960 coup d’etat. During his service, heexpressed that he did not approve some of the enforcements ofDemocrat Party, to which he was a member, such as making Kırşehir adistrict, arrangements at universities and cautions against theopposition during the speeches he gave in Grand National Assembly ofTurkey and party group. In the post-1960 coup d’etat period (27th ofMay, a Grand Jury was constituted which led the accusations madetowards DP members after the coup d’etat and some laws grantingextraordinary authorities were enacted. Osman Turan was not presentin the Assembly due to health problems which prevented him fromrating either favorably or unfavorably. His name was mentioned withthose of oppositions since he sometimes contradicted Menderes. Therewere even rumors that he would be expelled. However, Osman Turanpreferred to keep his battle within DP. He was arrested after coup d’etatand he gave his testimony on 30th of June in 1960 for the first time. Hewas put on trial within the scope of articles no. 141 and 146 fromTurkish Penal Code in the bylaw prepared by prosecution. The onlyaccusation made in the name of Osman Turan in the bylaw was theclaim that he received a certain amount of foreign currency. As a resultof evidence he provided in addition to his defense and investigation, itwas proven that the claims against him were unreal. He experiencedsome health problems during his arrest which lasted for 16.5 months.He could not attend all of the trials for he was being treated in thehospital located in garrison. Osman Turan was one of the 45 defendantswho were arrested due to violation of constitutional law on 15th ofSeptember 1961 and acquitted later on. 2 Mayıs 1954 seçimleri ile Demokrat Parti Trabzon Milletvekili olarak aktif siyasete atılan Osman Turan, 27 Mayıs 1960 Darbesi'ne kadar bu görevini sürdürmüştür. Milletvekilliği süresince mensubu bulunduğu Demokrat Partinin Kırşehir'in ilçe haline getirilmesi, üniversitelerde yapılan düzenlemeler, muhalefete karşı alınan tedbirler vb. uygulamalarını tasvip etmediğini TBMM ve parti grubunda yaptığı konuşmalarda dile getirmiştir. 27 Mayıs Darbesi sonrası DP mensuplarına yönelik suçlamaların başını çeken Tahkikat Encümeni oluşturulması ve bu encümene olağanüstü yetkiler veren kanunların çıkartılması sırasında da Osman Turan, sağlık problemleri nedeniyle mecliste bulunamamış dolayısı ile bu kanunlara lehte veya aleyhte oy vermemiştir. Menderes'le zaman zaman ters düştüğü için parti içerisinde adı, muhaliflerle birlikte anılmış hatta ihraç edileceği yönünde söylentiler ortaya atılmıştı. Fakat mücadelesini DP içerisinde sürdürme yolunu seçen Osman Turan, darbe ile birlikte tutuklanmış, ilk ifadesini de 30 Haziran 1960 tarihinde vermiştir. İddia makamı tarafından hazırlanan kararnamede, Türk Ceza Kanununun 141 ve 146ncı maddeleri kapsamında yargılanmıştır. Kararnamede Osman Turan'ın adının geçtiği tek suçlama ise bir miktar döviz aldığı iddiası olmuştur. Savunmasına ek olarak sunduğu deliller ve yapılan soruşturmalar sonucunda aleyhinde yapılan suçlamaların gerçek dışı olduğu kanıtlanmıştır. Toplam 16,5 ay tutukluluk döneminde sağlık problemleri yaşamış ve garnizondaki hastanede tedavi altına alındığı için duruşmaların tümüne iştirak edememiştir. Osman Turan, 15 Eylül 1961 tarihinde anayasayı ihlal suçundan tutuklu bulunup beraatına karar verilen 45 sanık arasında yer almıştır.

    Full Text Available The Brazilian fish fauna is still poorly known with respect to its diversity and conservation status, particularly of freshwater species. Human activities and population growth are rapidly impacting this fauna to an unchecked extent, so that many fish species are presently threatened. Also, some areas have been so critically altered that their fish fauna can no longer be properly inventoried. There is an urgent need to evaluate the conservation status of Brazilian fish species, since none are presently listed as endangered by federal legislation. Based on a literature search and a survey directed to the Neotropical ichthyologists, we present an unofficial list including a total of 78 threatened fish species (12 elasmobranchs and 66 actinopterygians. Of these, sixteen actinopterygian species are listed as endangered, three elasmobranchs and nine actinopterygians as vulnerable, and seven actinopterygians as rare; 40 species either have indeterminate status or are data deficient to yield an adequate assessment, and three species are listed as extinct or possibly extinct.

    Full Text Available OBJETIVO: Este estudio se ideó para describir el efecto de las intervenciones dirigidas a disminuir las muertes de los motociclistas. MATERIAL Y MÉTODOS: Se analizaron las variaciones en la mortalidad de motociclistas en Cali, al momento de aplicarse las intervenciones, y el significado estadístico de dichos cambios, entre 1993 y 2001. RESULTADOS: La tasa de muerte de motociclistas por cada 100 000 habitantes se redujo de 9.7 en 1995 a 3.6 en 2001. La mayor reducción se observó después de la introducción del uso del casco protector en 1996 (12.3%. Otras medidas como la obligatoriedad del casco para los pasajeros, el uso del chaleco reflectivo, la prohibición de usar motocicletas en días de diciembre y la exigencia de cursos para infractores redujeron en su conjunto aún más la mortalidad, mientras que el debilitamiento de la vigilancia la incrementó. CONCLUSIONES: La implantación y ejecución de medidas combinadas de prevención resultan más efectivas que las medidas individuales o desarticuladas.OBJECTIVE: Describe the impact of interventions focused on decreasing deaths by motorcycle crash. MATERIAL AND METHODS: We analyzed variations in deaths by motorcycle crash in Cali when the interventions were implemented and the statistical significance of changes between 1993 and 2001. RESULTS: The rate of motorcyclist deaths per 100 000 inhabitants decreased from 9.7 in 1995 to 3.6 in 2001. The greatest reduction was observed after the introduction of the helmet law for motorcycle drivers in 1996 (12.3%. Other interventions-such as a helmet law for passengers, a reflective safety vest, a circulation ban for motorcyclists in December, and compulsory courses for all motorcyclists-produced a greater decrease in mortality; meanwhile, a lack of law enforcement increased it. CONCLUSIONS: The establishment and implementation of a combination of prevention strategies was more effective than a single or non-articulated strategy.

    Full Text Available La noción de rendimiento escolar da cuenta de los resultados alcanzados por los/as estudiantes en su paso por la escuela. En su interior, encontramos dos tipos de fenómenos contrapuestos, el éxito y el fracaso escolar. La sociología de la educación ha permitido poner en cuestión ambas nociones, develando su carácter social y estrechamente vinculado con los marcos institucionales y socio-culturales en los que la escolarización se desenvuelve. El presente artículo, resultado de un trabajo de investigación desarrollado en el marco de nuestra tesis doctoral, se propone contribuir a iluminar los alcances de esa crítica, realizando un análisis de las trayectorias escolares de un grupo de mujeres mendocinas de sectores populares. Nos interesó contemplar, en primer término, las causas por las que abandonaron la escuela, aún niñas o adolescentes. Seguidamente, hemos abordado la cuestión de las oportunidades que les permitieron reingresar al sistema en la adultez, los obstáculos que debieron enfrentar y los recursos puestos en juego para poder completar el nivel medio.The notion of academic performance renders account of the results achieved by the students during their school education.  Internally, there are two opposed phenomena:  school success and school failure.  Sociology of education has contributed to the discussion of both notions revealing their social nature closely related to the institutional and socio-cultural contexts in which education is developed.  This paper is the result of a research project conducted for our doctoral thesis.  Its purpose is to contribute to enlighten the scopes of this discussion, by analyzing the school development of a group of working class women from Mendoza. We were interested, in the first place, in knowing the reasons why they quit school when they were young girls or adolescents.  Subsequently, we have approached the opportunities they had to access the system again during their adulthood, the obstacles they had to face and the resources to be able to complete the medium level.Recibido 30 de enero de 2012 • Corregido 17 de mayo de 2012 • Aceptado 28 de junio de 2012

    Full Text Available Los huracanes son disturbios comunes en el Caribe, pero se desconocen sus efectos sobre los carnívoros. El objetivo de este estudio fue evaluar la presencia y la abundancia relativa de los carnívoros respecto al daño en la vegetación debido al paso del huracán Dean (2007 en la península de Yucatán, 18 meses después del evento. Mediante fototrampeo, se muestrearon 4 sitios afectados en diferentes intensidades por el huracán. Se exploraron las respuestas de los carnívoros a 4 escalas espaciales. Los daños a la vegetación se estimaron mediante imágenes de satélite MODIS como la diferencia en el índice de Vegetación Mejorado (dEVI antes y después de que el huracán tocara tierra. En la mayoría de las escalas, la relación entre presencia y abundancia relativa de los carnívoros y el daño a la vegetación fue poco o nada significativa, probablemente debido a su poca especificidad de hábitat. Sin embargo, la aparente resistencia de estas especies al paso de un huracán debe confirmarse con un mayor esfuerzo de muestreo y un enfoque temporal.Hurricanes are common disturbances in the Caribbean, but their effect on carnivores is unknown. The objective of this study was to evaluate the occurrence and relative abundance of carnivores in relation with vegetation damage 18 months after Hurricane Dean (2007 hit the Yucatan Peninsula. Using camera-trapping, 4 sites showing different intensities of hurricane damage were sampled. The response of carnivores was explored at 4 spatial scales. Vegetation damage was estimated as the difference in the Enhanced Vegetation Index (dEVI before and after the hurricane using MODIS satellite images. At most resolutions, carnivores' occurrence and relative abundance were weakly or not related with vegetation damage, probably due to their little habitat specificity. Nevertheless, the apparent resistance of the studied species should be confirmed using a larger sampling effort and temporal framework.

  19. The role for saxagliptin within the management of type 2 diabetes mellitus: an update from the 2010 European Association for the Study of Diabetes (EASD 46th annual meeting and the American Diabetes Association (ADA 70th scientific session

    Aschner Pablo J

    2010-12-01

    Full Text Available Abstract Saxagliptin is a potent, selective DPP4 inhibitor. Highlights from abstracts presented at the 2010 meetings of the European Association for the Study of Diabetes and the American Diabetes Association include studies and analyses that shed light on the promising role for saxagliptin within the management of type 2 diabetes mellitus. Data show that saxagliptin combination therapy improves HbA1c levels compared with placebo, particularly in patients with high HbA1c at baseline, long duration of disease, low baseline creatinine clearance, and low homeostasis model assessment 2 β-cell function at baseline. These efficacy benefits are achieved without any increase in hypoglycemia or other adverse events. The study results also show that the saxagliptin plus metformin combination is a good candidate for initial therapy in drug-naïve patients treated for as long as 72 weeks. Survey data presented confirm that hypoglycemia (and fear of hypoglycemia is a barrier to patients' acceptance of diabetes treatment, limiting its efficacy. Therefore, therapies such as saxagliptin that have a low risk of hypoglycemia may be more acceptable to patients in helping them to achieve glycemic control and to optimize their quality of life. In patients with renal impairment, for whom metformin is contraindicated, saxagliptin monotherapy is a promising option for antidiabetic management as, when given at a reduced dose, it is well-tolerated with a safety profile similar to that of placebo.

  20. Choosing a software design method for real-time Ada applications: JSD process inversion as a means to tailor a design specification to the performance requirements and target machine

    Withey, James V.

    1986-01-01

    The validity of real-time software is determined by its ability to execute on a computer within the time constraints of the physical system it is modeling. In many applications the time constraints are so critical that the details of process scheduling are elevated to the requirements analysis phase of the software development cycle. It is not uncommon to find specifications for a real-time cyclic executive program included to assumed in such requirements. It was found that prelininary designs structured around this implementation abscure the data flow of the real world system that is modeled and that it is consequently difficult and costly to maintain, update and reuse the resulting software. A cyclic executive is a software component that schedules and implicitly synchronizes the real-time software through periodic and repetitive subroutine calls. Therefore a design method is sought that allows the deferral of process scheduling to the later stages of design. The appropriate scheduling paradigm must be chosen given the performance constraints, the largest environment and the software's lifecycle. The concept of process inversion is explored with respect to the cyclic executive.

    Full Text Available Los grupos prehispánicos tardíos que ocuparon las Sierras de Córdoba entre ca. 1200- 300 AP se caracterizaron por poseer una estrategia predominantemente agrícola, que se complementaba con el pastoreo y la caza- recolección (Berberián y Roldán 2001; Pastor y Medina 2003, 2004. Sin embargo, no se realizaron hasta el presente estudios específicos sobre restos arquebotánicos que hayan aportado un panorama acerca del aprove- chamiento de vegetales silvestres y/o cultivados. Por el contrario, el conocimiento sobre el empleo de estos recursos provino de evidencias indirectas, como la ubicación de las bases residenciales en terrenos potencialmente cultivables, la presencia de sitios pequeños al aire libre interpretados como campos de cultivo (Berberián y Roldán 2001; Medina y Pastor 2004 y el hallazgo de instrumentos relacio- nados con el laboreo agrícola (azuelas y con la molienda de granos (conanas y morteros.

    Full Text Available Inbreeding reduces the vigor in plants as a result of a decrease in the proportion of heterozygous loci. However, the influence of inbreeding is different among the species. The objective of this work was to evaluate the inbreeding depression in a cucumber Japanese population. An F2 population was obtained from a commercial hybrid (Natsu suzumi, which was considered as S0 population. S1, S2, S3, S4 and S5 progenies were obtained by the 'Single Seed Descent' methodology. A complete blocks design with seven treatments (different generations of self pollination - S0 to S5 and the hybrid Natsu suzumi, and six replications of five plants per plot was used in protected cultivation from Aug. 21 to Nov. 29, 2002. Number of leaves, length of the main stem, number and weight of fruits (total and commercial number of nodes and vines percentage were evaluated. For most of the traits appraised differences were not observed among populations showing that there was no loss of vigor due to inbreeding in this population.A endogamia reduz o vigor em plantas pela diminuição da proporção de loci heterozigotos. Entretanto, a influência da endogamia é diferente entre as espécies. O objetivo deste trabalho foi avaliar a depressão causada por endogamia em uma população de pepino do tipo japonês. A partir do intercruzamento entre plantas do híbrido Natsu suzumi foi obtida a geração F2, considerada como população S0. Obtiveram-se progênies S1, S2, S3, S4 e S5, através de autofecundações sucessivas pelo método do SSD ('Single Seed Descent'. Foram sete tratamentos (híbrido Natsu suzumi, populações S0 a S5 e o delineamento experimental foi em blocos ao acaso, com seis repetições e cinco plantas por parcela cultivadas em ambiente protegido de 21/08/2002 à 29/11/2002. Foram avaliados o número de folhas, semanalmente, o número e a massa de frutos, total e comercial, número de nós e porcentagem de nós com brotações laterais. Na comparação entre as populações S0 a S5 não foram observadas diferenças para todas as características avaliadas demonstrando não haver perda de vigor por endogamia nesta população.

    Full Text Available Objective: ADA is widely distributed in human tissues, which may contribute to the maturation of the immunological system, especially the proliferation and differentiation of lymphoid cells, and seems to be critical at different stages of the maturation process. The activity of ADA changes in diseases characterized by the alteration of cell-mediated immunity. In this study we examined changes in serum total ADA activity and the patterns of two ADA isoenzymes, ADA-1 and ADA-2, in healthy pregnant women, and evaluated the possible role of the alteration of cell-mediated immunity during pregnancy as causes of changes in ADA activity. Materials and Methods: We measured serum activities of total ADA, ADA-1 and ADA-2 in healthy pregnant women (n=129 and age-matched healthy nonpregnant women (n=42. We divided the study group into three different subgroups: first trimester, second trimester and third trimester. Results: Serum ADA, ADA-1 and ADA-2 activities in healthy pregnant women were significantly lower than in nonpregnant women (p<0.001, p<0.001 and p<0.01 respectively. ADA (p<0.001 and ADA-2 (p<0.001 activities in the first trimester were significantly lower than in the control group. However, there were no significant differences between the first trimester and control group according to their ADA-1 activities (p=0.016. ADA (p<0.001, ADA-1 (p<0.001 and ADA-2 (p<0.008 activities in the second trimester were significantly lower than in the control group. Combined trisomy 21 risk, biochemical trisomy 21 risk, age risk and trisomy 18 + Nuchal translucency (NT risk were calculated using a first trimester screening test in 63 pregnant women. Furthermore, trisomy 21 risk, age risk and trisomy 18 risk were calculated by triple test in 52 pregnant women. ADA, ADA-1 and ADA-2 activities were not significantly correlated with risks in the first trimester screening test. ADA-1 activity was slightly significantly negative correlated with age risk (r= -0

  15. Serum adenosine deaminase activity and its isoenzyme in patients treated for tuberculosis

    Objective: Increased serum adenosine deaminase (ADA) activity, mainly associated with tuberculosis can also occur in a number of other diseases thus negatively affecting the diagnostic utility of ADA measurements in tuberculosis. The aim of the study was to determine whether or not the combined use of the activity of ADA, its isoenzymes and differential cell counts would provide a more efficient means of diagnosing tuberculosis than the use of ADA levels alone. Results: Data suggested significant (p0.75) of ADA/sub 2/ADA was found to be better indicator of tuberculosis. Lymphocyte neutrophil ratio (L/N)> 0.69 gave additional benefit to increase the sensitivity and specificity for the use of ADA as marker in diagnosing tuberculosis. Conclusion: The combined use of activity of ADA, its isoenzymes and total and differential cell counts is a better indicator and gives better understanding to diagnose and evaluate tuberculosis and response to therapy.

  1. Evaluation of fibroblasts adhesion and proliferation on alginate-gelatin crosslinked hydrogel.

    Bapi Sarker

    Full Text Available Due to the relatively poor cell-material interaction of alginate hydrogel, alginate-gelatin crosslinked (ADA-GEL hydrogel was synthesized through covalent crosslinking of alginate di-aldehyde (ADA with gelatin that supported cell attachment, spreading and proliferation. This study highlights the evaluation of the physico-chemical properties of synthesized ADA-GEL hydrogels of different compositions compared to alginate in the form of films. Moreover, in vitro cell-material interaction on ADA-GEL hydrogels of different compositions compared to alginate was investigated by using normal human dermal fibroblasts. Viability, attachment, spreading and proliferation of fibroblasts were significantly increased on ADA-GEL hydrogels compared to alginate. Moreover, in vitro cytocompatibility of ADA-GEL hydrogels was found to be increased with increasing gelatin content. These findings indicate that ADA-GEL hydrogel is a promising material for the biomedical applications in tissue-engineering and regeneration.

  2. Dosimetric comparison of IMRT rectal and anal canal plans generated using an anterior dose avoidance structure

    To describe a dosimetric method using an anterior dose avoidance structure (ADAS) during the treatment planning process for intensity-modulated radiation therapy (IMRT) for patients with anal canal and rectal carcinomas. A total of 20 patients were planned on the Elekta/CMS XiO treatment planning system, version 4.5.1 (Maryland Heights MO) with a superposition algorithm. For each patient, 2 plans were created: one employing an ADAS (ADAS plan) and the other replanned without an ADAS (non-ADAS plan). The ADAS was defined to occupy the volume between the inguinal nodes and primary target providing a single organ at risk that is completely outside of the target volume. Each plan used the same beam parameters and was analyzed by comparing target coverage, overall plan dose conformity using a conformity number (CN) equation, bowel dose-volume histograms, and the number of segments, daily treatment duration, and global maximum dose. The ADAS and non-ADAS plans were equivalent in target coverage, mean global maximum dose, and sparing of small bowel in low-dose regions (5, 10, 15, and 20 Gy). The mean difference between the CN value for the non-ADAS plans and ADAS plans was 0.04 ± 0.03 (p < 0.001). The mean difference in the number of segments was 15.7 ± 12.7 (p < 0.001) in favor of ADAS plans. The ADAS plan delivery time was shorter by 2.0 ± 1.5 minutes (p < 0.001) than the non-ADAS one. The ADAS has proven to be a powerful tool when planning rectal and anal canal IMRT cases with critical structures partially contained inside the target volume

Os animais cruzados da G2, G3 e G4 foram, respectivamente, 14,95; 17,25 e 18,46% superiores aos puros quanto ao peso de corpo vazio (PCVZ. A heterose para o rendimento de carcaça fria em relação ao PCVZ (RCFCVZ foi positiva em todas as gerações. Os mestiços apresentaram menor peso relativo (ao PCVZ de coração, pulmões e rins, de modo que a heterose foi significativa para peso de coração (-18,29% e rins (-14,29% na G3 e para pulmões (-13,45% na G4. Novilhos mestiços apresentaram valores inferiores à média dos puros para todos os componentes do trato gastrintestinal quando o peso destes componentes foi expresso em relação a 100 kg de PCVZ ou de peso vivo ao abate (PVA, com exceção do rúmen na G2. A heterose retida foi positiva e significativa para PCVZ, RCFCVZ e para peso absoluto do fígado. Entretanto, foi negativa para a quantidade de sangue para os pesos de coração, intestino delgado + grosso e trato gastrintestinal quando expressos em relação a 100 kg de PCVZ e de PVA. Entre os animais puros, os novilhos Nelore tiveram maior RCFCVZ (57,09 vs 61,64%. O peso absoluto de rúmen, abomaso, intestino delgado + grosso e o trato gastrintestinal foram maiores nos novilhos Charolês em relação aos Nelore, o que também foi observado quando estes componentes foram expressos em relação ao PCVZ e PVA, com exceção para o intestino grosso + delgado. Estas diferenças explicam, em parte, o maior rendimento de carcaça dos novilhos Nelore.The objective of this trial was to investigate the effect of heterosis and genetic group on the yield and weight of internal organs and gastrointestinal tract (GIT of feedlot purebred (Charolais C and Nellore N and crossbred steers from second (G2 (¾C ¼N and ¾N ¼C, third (G3 (5/8C 3/8N and 5/8N 3/8C and fourth (G4 (11/16C 5/16N and 11/16N 5/16C generations of rotational crossbreeding slaughtered at 23 month of age. Crossbred steers from G2, G3 and G4 had, respectively, 14.95, 17.25 and 18.46% higher empty body weight (EBW than that from purebred animals. A positive heterosis for cold carcass yield expressed as a proportion of EBW (CCYEBW was observed in G2, G3, and G4. Weights of heart, lungs, and kidneys adjusted for EBW were lower on crossbred compared to purebred steers; the heterosis was significant for the weights of heart (-18.29% and kidneys (-14.29% in G3 and for that of lungs (-13.45% in G4. Weights of all organs of the GIT either expressed as 100 kg of EBW or as proportion of slaughter body weight (SBW were lower on crossbred than on purebred steers with the exception of rumen weight in G2. Retained heterosis was positive and significant for EBW, CCYEBW and liver weight. However, it was negative for amount of blood and weights of heart and small plus large intestines when expressed as 100 kg of EBW and SBW. Within purebred animals, N showed greater CCYEBW (61.64% than C (57.09. Conversely, weights of rumen, abomasum, small plus large intestine, and GIT were all higher on C than N steers; excepting for small plus large intestine, the same was observed when weights of the remaining GIT components were expressed as proportion of EBW and SB. These differences partially explain the increased carcass yield on N steers.

The paper analyses three of the most important vector processes involved in the profound anthropological mutation of the urban experience: the glocal , dromocrac y and transpolitics processes, along with their derivatives, the glocalization and dromocratisation of individual and collective existence and the transpoliticisation of contemporary social trends. Heterodox modulators of the urban experience that have as yet been little explored by theoretical reflection, these matrix processes, by the fact of taking communication networks and technologies (mass and interactive as their central premise, can explain three of the most important (and impressive phenomena related to the city (as a social-historical invention and as bequeathed urbanistic and architectural equipment and the present experience of the city environment: [1] the reinvention of space in the context of access to communication networks (the fractalised glocalisation of territory , [2] the conversion of the city into passage flows (inasmuch as the traffic of information along networks is mirrored ( urban dromocratisation , and [3] the depopulation of the city's public areas – the prime location of political action and of the collective subject – in favour of new bastions of sociability that are created and decorated by a strong commercial and advertising concentration ( transpolitisation of the disinvestment in the inherited social sphere .

  7. Capacidade resistente e modos de ruptura de vigas de concreto armado reforçadas à flexão com fibras de carbono Resistant capacity and failure modes of reinforced concrete beams strengthened in flexure with externally bonded carbon fiber reinforced plastic

    Full Text Available Para se projetar um reforço à flexão com material polimérico reforçado com fibras, em uma viga de concreto armado, é necessário que o engenheiro responsável opte por trabalhar sem a utilização de mecanismos de incremento de ancoragem, obviamente dentro de níveis seguros, ou utilize artifícios que lhe garantam alcançar a deformação última de projeto da fibra fornecida pelo fabricante da manta. Nesse artigo, é apresentada a base para o cálculo das duas metodologias, segundo os critérios mais expressivos existentes, e são feitas comparações com resultados experimentais. Para o reforço sem ancoragem, verificou-se que, para se evitarem as indesejadas rupturas prematuras e bruscas, as metodologias propostas pelos ACI e FIB mostraram-se adequadas. Para se garantir a deformação última da fibra, foi estudado um mecanismo com ancoragem lateral a 45° feito com o próprio material da fibra. Nesse caso, utilizou-se o processo de seções balanceadas, para a previsão do modo de ruptura, e, em seguida, foram feitas as devidas comparações entre os valores esperados com os resultados obtidos nos ensaios em laboratório.To design an externally bonded fiber reinforced plastic reinforcement for a reinforced concrete beam, it is necessary that the engineer responsible chooses to work without the use of mechanisms to increase the anchoring within safe levels, or make use of artifacts to ensure that the deformation in the fiber reaches ultimate state value supplied by the manufacturer. This article shows the basis for the calculation of the two methodologies under the existing criteria more expressively and also makes comparisons with laboratory tests. For enhancement without anchoring, it was found that to prevent unwanted premature and abrupt ruptures, the methods proposed by ACI and FIB showed to be adequate. To ensure the ultimate deformation of the fiber, a mechanism for anchoring in the form of a bow 45º made by the material of the fiber was studied. In this case, the process of balanced sections to foresee the mode of collapse were verified and then the appropriate comparisons were made between the expected values with the tests results found in the laboratory.

    Full Text Available Este trabalho propôs a montagem experimental de um túnel portátil de congelamento por ar forçado composto por um ventilador que produz uma região de alta ou baixa pressão em um palete com produto, onde se pode avaliar o processo com a utilização de insuflação, exaustão de ar e uma combinação mista destes dois processos. O equipamento foi alocado no interior de uma câmara de estocagem de produtos congelados, buscando-se melhorar a distribuição do ar, potencializando-se a troca térmica entre o ar e o produto. Durante o congelamento, foram comparados os processos e analisada a transferência de calor entre o ar de resfriamento e o produto em diferentes posições e camadas do palete, bem como a distribuição do ar de resfriamento em circulação ao redor do produto. O processo de exaustão apresentou uma redução de 14% do tempo para o congelamento em relação à insuflação e 10% em relação ao misto.The objective of this work is to build an experimental portable forced-air freezing tunnel which creates a low or high pressure region surrounding the product. Comparative studies with air exhausting and blowing were conducted. The tunnel was built and placed inside a freezing product storage chamber, and the objective was to improve the air circulation and the thermal distribution between the product and cold air for a sample batch left inside the chamber. A heat transfer analysis comparing the process and the air distribution around the product was performed. The air evacuation process reduced up to 14% of the freezing time in relation to the blowing system and 10% in relation to the mixed system.

    2011-06-01

    Full Text Available Bactérias produtoras de auxinas habitam raízes de orquídeas e podem trazer benefícios para a planta hospedeira. Plantas dessa família são multiplicadas em condições assimbióticas in vitro e pouco se conhece sobre a função desses microrganismos para a aclimatização ex vitro. Quatro rizobactérias isoladas da espécie Cattleya walkeriana foram avaliadas por sua capacidade de promoção do crescimento e sobrevivência de plântulas germinadas in vitro durante a aclimatização. Essas rizobactérias foram identificadas como Bacillus, Burkholderia, Enterobacter e Curtobacterium, com base no sequenciamento do gene 16S rRNA. A presença de compostos indólicos no sobrenadante filtrado de culturas líquidas foi quantificada por ensaios colorimétricos e cromatografia líquida de alta eficiência (CLAE. Ácidos 3-indol lático (AIL e indol-3-acetaldeído (AIAld foram encontrados em grande quantidade, exceto na cultura de Enterobacter sp., em que ácido 3-indol acético (AIA e ácido 3-indol pirúvico (AIP prevaleceram. As rizobactérias foram inoculadas em plântulas germinadas in vitro, aclimatizadas em casa de vegetação durante 90 dias e avaliadas quanto à sua capacidade de promover o crescimento. Burkholderia sp. e Curtobacterium sp. proporcionaram a menor eficiência para o crescimento, enquanto Bacillus sp. e Enterobacter sp. favoreceram incrementos em todas as características avaliadas e ampliaram a percentagem de sobrevivência. Este trabalho elucida a função de rizobactérias produtoras de auxinas e seus benefícios para a promoção de crescimento de uma orquídea brasileira germinada em condições assimbióticas durante a aclimatização - condição que confere alta letalidade e limitante para a propagação de orquídeas.

  14. Influence of secondary packing on the freezing time of chiken meat in air blast freezing tunnels Influência da embalagem secundária sobre o tempo de congelamento de carne de frango em túneis de circulação de ar forçada

    Clarice de Ávila Santos

    2008-12-01

    Full Text Available Freezing of poultry cuts in continuous convective air blast tunnels is normally performed with the products protected by Low Density Polyethylene (LDPE as a primary packaging and using Corrugated Cardboard Boxes (CCB as secondary packaging. The objective of this work was to investigate the influence of these secondary packaging on the freezing of poultry cuts in continuous convective air blast tunnels. The study was performed by replacing CCB with Perforated Metal Boxes (PMB in order to remove the packaging thermal resistance. The assays, performed in a industrial plant, demonstrated that CCB used commercially for meat freezing have a high heat transfer resistance. Their replacement with PMB can lead to shorter freezing times and spatially homogeneous freezing. Reductions of up to 45% in the freezing times were observed using PMB. The plateau of the temperature curve, related to the freezing time of free water, was significantly reduced using PMB, which is accepted to lead to better product quality after thawing. As the products were protected by the LDPE films as primary packaging, their appearance were not affected. The results presented in this work indicate that replacing CBB with PMB can be an excellent alternative to reduce freezing time and improve freezing homogeneity in industrial air blast tunnels, which could also be applied to other products.O congelamento de cortes de frango em túneis convectivos é normalmente realizado com o produto envolto por filmes de polietileno de baixa densidade (PEBD, embalagem primária e acondicionado em caixas de papelão (CP, embalagem secundária. O objetivo deste trabalho foi avaliar o efeito da embalagem secundária no congelamento dos cortes de frango. Para isso, compararam-se as curvas de congelamento do produto processado acondicionado em caixas metálicas perfuradas (CMP, que praticamente eliminam a resistência térmica da embalagem secundária, com as curvas de congelamento do produto nas CP. Os ensaios, realizados em uma planta industrial de processamento de aves, indicaram que as CP possuem uma grande resistência térmica e que a substituição delas por PMB pode resultar em maior homogeneidade espacial do processo de congelamento e em tempos de processo 45% inferiores. A duração do patamar de temperaturas que caracteriza a etapa de solidificação foi sensivelmente reduzida, o que favorece a obtenção de produtos congelados de melhor qualidade. A aparência dos produtos congelados em CMP não foi afetada, devido à proteção oferecida pelo PEBD. Assim, a substituição das caixas de papelão por caixas metálicas perfuradas pode ser uma excelente alternativa para reduzir o tempo de congelamento e melhorar sua homogeneidade espacial em túneis industriais.

    Full Text Available RESUMO: Neste trabalho foi estudada a influência da adição de compatibilizantes, da composição e dos parâmetros de processamento nas propriedades reológicas, morfológicas e mecânicas de blendas de polipropileno com poliamidas aromáticas, adicionadas de fibras de vidro, obtidas por moldagem por injeção. Os resultados obtidos mostram que a adição de um compatibilizante melhora a adesão entre as fases da blenda, apresentando um papel emulsificante e estabilizador da morfologia da blenda. Utilizando-se um reômetro "in line" na máquina de injeção, e através de observações morfológicas, foi mostrado que ocorre uma evolução significativa da morfologia em função dos parâmetros de processamento e da composição da blenda. A orientação das fibras de vidro em função da posição dentro do molde foi também estudada neste trabalho, demonstrando a existência de três camadas distintas no molde.ABSTRACT: In this work, the influence of compatibilization, blend composition and processing parameters on the rheological, morphological and mechanical properties were studied for blends of polypropylene with aromatic polyamide with glass fibers obtained by injection molding. It was shown that the compatibilizer improves the adhesion at the interface, emulsifies and stabilizes the morphology. Using rheological data obtained with an in-line rheometer, localized in the injection molding machine and morphological observations, it was shown that significant evolution of phase structure occurred depending on processing or compounding parameters. Also, the orientation of the glass fibers was studied as a function of the position in the mold cavity, showing the presence of three layers of different morphology in the molding.

Os novilhos foram alimentados com a mesma dieta, contendo 12,32% de proteína bruta e 2,96 Mcal de energia digestível/kg de matéria seca, com relação volumoso:concentrado de 52:48. Os consumos médios diários de matéria seca, energia digestível e de fibra em detergentes neutro e ácido, expressos em kg/animal, foram maiores nos animais mestiços em todas as gerações de cruzamento. No entanto, quando estes consumos foram expressos por 100 kg de peso vivo, as diferenças deixaram de ser significativas. A heterose retida (5,46% foi significativa para ganho de peso médio diário. As heteroses para eficiências alimentar (ganho de peso/kg de matéria seca e energética (ganho de peso/Mcal de energia digestível foram negativas em todas gerações, indicando que novilhos mestiços foram menos eficientes que a média dos puros. As porcentagens de heterose para estado corporal e pesos corporais inicial e final foram expressivas e significativas em todas as gerações. O comportamento do grau de heterose nestas características acompanhou a oscilação da heterozigose individual. O cruzamento rotativo gerou mestiços superiores quanto ao consumo de matéria seca e ao peso e estado corporal, em relação aos animais puros. Os animais mestiços apresentaram mesma eficiência alimentar que os Nelore, mas foram inferiores aos Charolês quanto à eficiência alimentar e ao ganho de peso médio diário.The objective of this study was to evaluate body condition, weight, weight gain, food intake and efficiency of feedlot finished steers, purebreds (Charolais - C and Nellore - N, crossbreds from second (G2 (¾C ¼N and ¾N ¼C, third (G3 (5/8C 3/8N and 5/8N 3/8C and fourth (G4 (11/16C 5/16N and 11/16N 5/16C generations of rotational crossbreeding. The steers were fed the same diet containing 12.32% crude protein, 2.96 Mcal digestible energy/kg of dry matter and roughage:concentrate ratio of 52: 48. Average daily intakes of dry matter, digestible energy, neutral and acid detergent fiber expressed by kg/animal were higher for crossbreds in all generations. However, when these intakes were expressed per 100 kg of body weight differences were not significant. Retained heterosis (5.46% was significant for average daily weight gain. Heterosis for efficiency of feed (kg of weight gain/kg of dry matter and energy (kg of weight gain/Mcal of digestible energy were negative in all generations, indicating that crossbred steers were less efficient than purebreds. Heterosis (% for initial and final body weights and condition were expressive and significant in all generations and the level of heterosis for these traits followed the fluctuation of individual heterozygosis. Rotational crossbreeding animals were superior to purebreds for dry matter intake, body weight and condition, similar to Nellore for feed efficiency and inferior to Charolais for feed efficiency and average daily weight gain.

    Full Text Available Visando o aproveitamento de resíduos de laminados de poliéster insaturado com fibra de vidro, foi realizado o estudo da incorporação do resíduo moído em placas confeccionadas à base de resina poliéster insaturado pelo processo de moldagem por compressão de preformas (BMC. Foram testadas cinco formulações com diferentes quantidades de resina poliéster, resíduo moído, aditivos e cargas. As placas foram confeccionadas em prensa hidráulica com molde plano e pressões da ordem de 18,1 MPa à temperatura de 115 ºC. Os corpos de prova, preparados segundo normas ASTM, foram submetidos a ensaios de tração, impacto Charpy e dureza do material. Os resultados dos ensaios mecânicos indicam que a substituição de fibra de vidro pelo resíduo moído no compósito polimérico promove perda de resistência à flexão, ao impacto Charpy e a dureza do compósito; a resistência à tração mostra que a incorporação do resíduo pode ter um aumento de 23% quando a quantidade de resíduo adicionada é de 20% p/p.In this work we studied the incorporation of fiberglass residues in plates made of insatured polyester resin by bulk molding compound process (BMC. Five different mixtures were made and their mechanical properties were determined. The results showed that using residues instead of fiberglas produces a decrease of the flexural strength, Charpy impact strength and hardness; however depending on the percentage of residue, the tensile strength may have a significant increase.

  2. : The glocal bunker and its paradox: operational dialetic between "reclosure" and "openness" in advanced mediatic civilization. O bunker glocal e seu paradoxo: dialética operacional entre "refechamento" e "abertura" na civilização mediática avançada.

    Eugênio Trivinho

    2009-06-01

    Full Text Available in advanced mediatic civilization — In this article, the author reflects upon the sociohistorical signification of the glocal bunker today — the mediatic bunker of cyberculture (cyberspace, which, extending beyond the global and the local, within the very fabric of planetary glocaliza- tion, culturally rearticulates and reinforces the process of obliterated militarization of social life. His discussion dissects an autopoietic sociophenomenological and fundamental filigrain of the material and subjective experience of this bunker: a paradoxical intra-operational movement which simultaneously encompasses "reclosure" and "openness" in relation to the world, and particularly to alterity. This peculiar paradox conceals the way in which the collective and indi- vidual appropriation by the majority of digital networks is expressed in the sociohistorical and in quotidian life. In effect, internationally established cyber-overoptimistic discourse promotes the "openness" brought about by interactivity as the only fact worthy of attention in the current stage of the productive forces. The material and subjective "reclosure" it also represents is discarded as a mere historical exception, accident or minor inconvenience. The present study examines the naiveté of this epochal fallacy. "Openness" can only be understood if in inter-remission with the tendency for "reclosure". If, in cyberculture, there is no confinement or total atomization of the subject, neither is there an unquestionable horizon absolutely free to him. O artigo desdobra a reflexão do autor sobre a significação social-histórica do bunker glocal na atualidade — bunker mediático da cibercultura (o cyberspace que, vigorando para além do global e do local, já no tecido próprio da glocalização planetária, rearticula e reforça, cul- turalmente, o processo de militarização obliterada da vida social. A argumentação disseca uma filigrana sociofenomenológica autopoiética e fundamental da experiência material e subjetiva desse bunker: um movimento intra-operacional paradoxal no qual se encerram, simultanea- mente, "refechamento" e "abertura" em relação ao mundo e, em particular, à alteridade. Tal paradoxo peculiar recobre o modo pelo qual a apropriação coletiva e individual majoritária das redes digitais se expressa no social-histórico e na vida cotidiana. Com efeito, discursos ciberufanistas internacionalmente vigentes promovem a "abertura" trazida pela interatividade como o único fato digno de atenção no estágio atual das forças produtivas. O "refechamento" material e subjetivo que ele também representa fica descartado como mera excepcionalidade histórica, acidente ou mal menor. O artigo tensiona a ingenuidade política dessa falácia epocal. A "abertura" só pode ser compreendida se em interremissão com a tendência de "refechamen- to". Se, na cibercultura, inexiste confinamento ou atomização total do sujeito, tampouco se verifica aprumo inquestionável de horizonte absolutamente livre para ele.

  4. Responsabilização ameaçada: sobre falar “bobagem” em educação = Threatened accountability: about talking “Bullshit” in education = Responsabilización amenazada: sobre hablar de “bobadas” en la educación

    Kesselring, Thomas

    2014-01-01

    Full Text Available Em seu livro On Bullshit, Harry Frankfurt constata uma trivialização crescente tanto na comunicação humana quanto na produção de textos. À primeira vista, Bullshit (falar bobagem parece ser uma expressão semelhante à mentira. No entanto, o mentiroso mantém a distinção entre o verdadeiro e o falso, enquanto o Bullshiter faz pouco caso desta distinção. Desse modo, o Bullshit se aproxima do blefe. Qual é a causa do aumento da produção de Bullshit? Frankfurt sugere que isso se deve ao achatamento do discurso político. Mas como podemos explicar esse fenômeno? Mesmo com o elevado nível de sua análise, Frankfurt esquece de mencionar uma característica da atual sociedade de mercado, ou seja, o papel cada vez mais importante do marketing. Quando a cultura da concorrência e do marketing começou a fazer parte da educação superior, práticas que originariamente nada têm a ver com a educação, como a jactância, o engano, ranking e benchmarking passaram a pervadir e perverter também o ensino superior. Este artigo descreve e analisa as excrescências esquisitas desse processo.

  5. Perspectives for using light quality knowledge as an advanced ecophysiological weed management tool Perspectivas da utilização da qualidade da luz como uma avançada ferramenta ecofisiológica para o manejo de plantas daninhas

    Full Text Available The current knowledge of light quality effects on plant morphogenesis and development represents a new era of understanding on how plant communities perceive and adjust to available resources. The most important consequences of light quality cues, often mediated by decreasing in red far-red ratios with respect to the spectral composition of incident sunlight radiation, affecting weed-crop interaction are the increased plant height and shoot to root ratio in anticipation of competition by light quantity, water or nutrients. Although the concepts related to light quality have been extensively studied and several basic process of this phenomenon are well known, little applications of photomorphogenic signaling currently are related to agricultural problems or weed management. The objectives of this review are to describe how light quality change can be a triggering factor of interspecific interference responses, to analyze how this phenomenon can be used to predict weed interference, to reevaluate the critical periods of interference concept, and to discuss its potential contribution towards developing more weed competitive crop varieties. Knowledge on light quality responses involved in plant sensing of interspecific competition could be used to identify red/far-red threshold values, indicating when weed control should be started. Light quality alterations by weeds can affect grain crop development mainly in high yielding fields. Unlike the traditional concept or the critical period of competition, light quality mediated interference implies that the critical period for weed control could start before the effects of direct resource (water, nutrients and available light limitation actually occur. The variability in light quality responses among crop genotypes and the identification of mutants insensitive to light quality effects indicate that this characteristic can be selected or modified to develop cultivars with enhanced interspecific interference ability. Knowledge on light quality-elicited responses represents a new possibility to understand the underlying biology of interspecific interference, and could be used in the development of new weed management technologies.O atual conhecimento sobre os efeitos da qualidade da luz representa uma nova era da compreensão dos processos envolvidos na percepção e ajuste das plantas em função dos recursos disponíveis no ambiente. As consequências mais importantes da diminuição da qualidade de luz, que se relaciona principalmente com a diminuição da relação vermelho/vermelho-extremo, que ocorrem nas interações entre culturas e plantas daninhas são o aumento da estatura e da relação parte aérea/raiz. Essas alterações são tentativas de antecipar os efeitos da concorrência futura por quantidade de luz, água ou nutrientes. Embora vários conhecimentos básicos relacionados com a qualidade da luz tenham sido desenvolvidos há muito tempo, poucas aplicações da sinalização fotomorfogênica têm sido implementadas em processos relacionados com a agricultura e, principalmente, com o manejo de plantas daninhas. Os objetivos deste trabalho foram: descrever a diminuição da qualidade da luz como um fator desencadeante da competição interespecífica; analisar como a qualidade da luz pode ser usada para predizer o início da interferência das plantas daninhas; reavaliar os períodos críticos de interferência; e discutir o potencial de desenvolvimento de cultivares mais competitivas com as plantas daninhas. O conhecimento dos fatores envolvidos na qualidade da luz pode ser utilizado para identificação de uma relação da radiação vermelho/vermelho-distante que indique o início da competição interespecífica e possa ser usada com um nível de dano referencial, indicando quando o controle das plantas daninhas deve ser iniciado. Os efeitos da baixa qualidade de luz podem limitar o desenvolvimento das culturas, sobretudo em situações de lavouras com elevados níveis potenciais de rendimento de grãos. Nessas situações, o período crítico para controle de plantas daninhas deve ser considerado antes de se iniciarem os efeitos da limitação dos recursos de água, nutrientes e quantidade de luz, que representa o tradicional período crítico de competição. A existência de variabilidade de genótipos das culturas à qualidade da luz e a identificação de mutantes insensíveis aos efeitos da baixa qualidade da luz indicam que essa característica pode ser selecionada ou transformada para o desenvolvimento de cultivares com maior capacidade de competição com as plantas daninhas. Os conhecimentos relacionados com a qualidade da luz representam uma nova possibilidade de compreender a biologia da competição interespecífica e poderão ser utilizados no desenvolvimento de novas tecnologias para o manejo de plantas daninhas.

    Full Text Available Pré-polímeros fenólicos e lignofenólicos (substituição de 40% em massa de fenol por lignina, extraída do bagaço de cana foram sintetizados para preparar compósitos com matrizes termofixas, usando bagaço de cana-de-açúcar como agente de reforço. Este material lignocelulósico foi modificado por métodos químicos e/ou físicos (tratamento com álcali, esterificação, ar ionizado. O bagaço de cana promoveu pequeno aumento na resistência ao impacto das matrizes fenólica e lignofenólica. Os métodos de tratamento de superfície melhoraram a dispersão das fibras na matriz assim como a adesão entre ambas as resinas, fenólica e lignofenólica, e as fibras lignocelulósicas. Apenas os compósitos tratados com ar ionizado mostraram melhores resultados de resistência ao impacto. Em relação à absorção de água, foi observado que os compósitos fenólicos reforçados com fibras tratadas com 8 % NaOH apresentaram uma menor absorção de água. Quanto aos compósitos lignocelulósicos, os reforçados com fibras esterificadas apresentaram uma menor absorção de água.

  7. Increased level of soluble adenosine deaminase in bone marrow of visceral leishmaniasis patients: an inverse relation with parasite load.

    Rai, Ambak K; Kumar, Prabin; Saini, Sheetal; Thakur, Chandreshwar P; Seth, Tulika; Mitra, Dipendra K

    2016-09-01

    Adenosine deaminase (ADA) which degrades adenosine to inosine, is known to be pro-inflammatory molecule in many diseases. Adenosine suppresses the functioning of the immune system and thus promotes dissemination of the parasite. In our previous finding, the level of soluble ADA in serum of visceral leishmaniasis (VL) was found to be increased as compared to healthy controls. However, it cannot be fairly interpreted unless their level is demonstrated at the disease site, where the parasite resides. We designed this study to correlate the level of soluble ADA (sADA) with parasitic load at the disease site i.e. bone marrow (BM). We found increased levels of sADA in BM as compared to the unaffected BM. Furthermore, a significant inverse correlation is observed between the parasite load and level of sADA at the disease site.

    McBean, Sam

    2014-01-01

    This paper will consider the relationship between the body, reproduction, and feminist history in Lynn Hershman Leeson's 1997 film Conceiving Ada. The film focuses on contemporary computer scientist Emmy's attempt to save Ada, Countess of Lovelace, from being forgotten from history. The main threat to both Ada and Emmy's work is their respective pregnancies and thus the film at first seems to represent the female body's biological reproduction as antagonistic to the (desired) reproduction of ...

  17. ADENOSINE DEAMINASE ACTIVITY AND SERUM C-REACTIVE PROTEIN AS PROGNOSTIC MARKERS OF CHAGAS DISEASE SEVERITY

    Iván Darío BRAVO-TOBAR

    2015-10-01

    Full Text Available SUMMARY Chagas disease is a public health problem worldwide. The availability of diagnostic tools to predict the development of chronic Chagas cardiomyopathy is crucial to reduce morbidity and mortality. Here we analyze the prognostic value of adenosine deaminase serum activity (ADA and C-reactive protein serum levels (CRP in chagasic individuals. One hundred and ten individuals, 28 healthy and 82 chagasic patients were divided according to disease severity in phase I (n = 35, II (n = 29, and III (n = 18. A complete medical history, 12-lead electrocardiogram, chest X-ray, and M-mode echocardiogram were performed on each individual. Diagnosis of Chagas disease was confirmed by ELISA and MABA using recombinant antigens; ADA was determined spectrophotometrically and CRP by ELISA. The results have shown that CRP and ADA increased linearly in relation to disease phase, CRP being significantly higher in phase III and ADA at all phases. Also, CRP and ADA were positively correlated with echocardiographic parameters of cardiac remodeling and with electrocardiographic abnormalities, and negatively with ejection fraction. CRP and ADA were higher in patients with cardiothoracic index ≥ 50%, while ADA was higher in patients with ventricular repolarization disturbances. Finally, CRP was positively correlated with ADA. In conclusion, ADA and CRP are prognostic markers of cardiac dysfunction and remodeling in Chagas disease.

  18. Recombinant adeno-associated virus-mediated gene transfer for the potential therapy of adenosine deaminase-deficient severe combined immune deficiency.

    Silver, Jared N; Elder, Melissa; Conlon, Thomas; Cruz, Pedro; Wright, Amy J; Srivastava, Arun; Flotte, Terence R

    2011-08-01

    Severe combined immune deficiency due to adenosine deaminase (ADA) deficiency is a rare, potentially fatal pediatric disease, which results from mutations within the ADA gene, leading to metabolic abnormalities and ultimately profound immunologic and nonimmunologic defects. In this study, recombinant adeno-associated virus (rAAV) vectors based on serotypes 1 and 9 were used to deliver a secretory version of the human ADA (hADA) gene to various tissues to promote immune reconstitution following enzyme expression in a mouse model of ADA deficiency. Here, we report that a single-stranded rAAV vector, pTR2-CB-Igκ-hADA, (1) facilitated successful gene delivery to multiple tissues, including heart, skeletal muscle, and kidney, (2) promoted ectopic expression of hADA, and (3) allowed enhanced serum-based enzyme activity over time. Moreover, the rAAV-hADA vector packaged in serotype 9 capsid drove partial, prolonged, and progressive immune reconstitution in ADA-deficient mice. Overview Summary Gene therapies for severe combined immune deficiency due to adenosine deaminase (ADA) deficiency (ADA-SCID) over two decades have exclusively involved retroviral vectors targeted to lymphocytes and hematopoietic progenitor cells. These groundbreaking gene therapies represented an unprecedented revolution in clinical medicine but in most cases did not fully correct the immune deficiency and came with the potential risk of insertional mutagenesis. Alternatively, recombinant adeno-associated virus (rAAV) vectors have gained attention as valuable tools for gene transfer, having demonstrated no pathogenicity in humans, minimal immunogenicity, long-term efficacy, ease of administration, and broad tissue tropism (Muzyczka, 1992 ; Flotte et al., 1993 ; Kessler et al., 1996 ; McCown et al., 1996 ; Lipkowitz et al., 1999 ; Marshall, 2001 ; Chen et al., 2003 ; Conlon and Flotte, 2004 ; Griffey et al., 2005 ; Pacak et al., 2006 ; Stone et al., 2008 ; Liu et al., 2009 ; Choi et al., 2010

  19. Mutations in the human adenosine deaminase gene that affect protein structure and RNA splicing

    Adenosine deaminase deficiency is one cause of the genetic disease severe combined immunodeficiency. To identify mutations responsible for ADA deficiency, the authors synthesized cDNAs to ADA mRNAs from two cell lines, GM2756 and GM2825A, derived from ADA-deficient immunodeficient patients. Sequence analysis of GM2756 cDNA clones revealed a different point mutation in each allele that causes amino acid changes of alanine to valine and arginine to histidine. One allele of GM2825A also has a point mutation that causes an alanine to valine substitution. The other allele of GM2825A was found to produce an mRNA in which exon 4 had been spliced out but had no other detrimental mutations. S1 nuclease mapping of GM2825A mRNA showed equal abundance of the full-length ADA mRNA and the ADA mRNA that was missing exon 4. Several of the ADA cDNA clones extended 5' of the major initiation start site, indicating multiple start sites for ADA transcription. The point mutations in GM2756 and GM2825A and the absence of exon 4 in GM2825A appear to be directly responsible for the ADA deficiency. Comparison of a number of normal and mutant ADA cDNA sequences showed a number of changes in the third base of codons. These change do not affect the amino acid sequence. Analyses of ADA cDNAs from different cell lines detected aberrant RNA species that either included intron 7 or excluded exon 7. Their presence is a result of aberrant splicing of pre-mRNAs and is not related to mutations that cause ADA deficiency

  20. MicroRNA-146b-3p Regulates Retinal Inflammation by Suppressing Adenosine Deaminase-2 in Diabetes

    Sadanand Fulzele

    2015-01-01

    Full Text Available Hyperglycemia- (HG- Amadori-glycated albumin- (AGA- induced activation of microglia and monocytes and their adherence to retinal vascular endothelial cells contribute to retinal inflammation leading to diabetic retinopathy (DR. There is a great need for early detection of DR before demonstrable tissue damages become irreversible. Extracellular adenosine, required for endogenous anti-inflammation, is regulated by the interplay of equilibrative nucleoside transporter with adenosine deaminase (ADA and adenosine kinase. ADA, including ADA1 and ADA2, exists in all organisms. However, because ADA2 gene has not been identified in mouse genome, how diabetes alters adenosine-dependent anti-inflammation remains unclear. Studies of pig retinal microglia and human macrophages revealed a causal role of ADA2 in inflammation. Database search suggested miR-146b-3p recognition sites in the 3′-UTR of ADA2 mRNA. Coexpression of miR-146b-3p, but not miR-146-5p or nontargeting miRNA, with 3′-UTR of the ADA2 gene was necessary to suppress a linked reporter gene. In the vitreous of diabetic patients, decreased miR-146b-3p is associated with increased ADA2 activity. Ectopic expression of miR-146b-3p suppressed ADA2 expression, activity, and TNF-α release in the AGA-treated human macrophages. These results suggest a regulatory role of miR-146b-3p in diabetes related retinal inflammation by suppressing ADA2.

  11. Hereditary overexpression of adenosine deaminase in erythrocytes: Evidence for a cis-acting mutation

    Chen, E.H. (Univ. of Michigan, Ann Arbor, MI (United States)); Tartaglia, A.P. (Albany Medical College, Albany, MI (United States)); Mitchell, B.S. (Univ. of North Carolina, Chapel Hill, NC (United States))

    1993-10-01

    Overexpression of adenosine deaminase (ADA) in red blood cells is inherited as an autosomal dominant trait and causes hemolytic anemia. The increased ADA activity in erythrocytes is due to an increase in steady-state levels of ADA mRNA of normal sequence. Increased ADA mRNA may be due to a cis-acting mutation which results in increased transcription or a loss of down-regulation during erythroid differentiation. Alternatively, it is possible that the mutation is in a trans-acting factor which interacts with normal ADA transcriptional elements to cause overexpression in red blood cells. To discriminate between a cis-acting and a trans-acting mutation, the authors took advantage of a highly polymorphic TAAA repeat located at the tail end of an Alu repeat approximately 1.1 kb upstream of the ADA gene. Using PCR to amplify this region, the authors identified five different alleles in 19 members of the family. All 11 affected individuals had an ADA allele with 12 TAAA repeats, whereas none of the 8 normal individuals did. The authors conclude that this disorder results from a cis-acting mutation in the vicinity of the ADA gene. 24 refs., 3 figs.

  12. A 24-Year Enzyme Replacement Therapy in an Adenosine-deaminase-Deficient Patient.

    Tartibi, Hana M; Hershfield, Michael S; Bahna, Sami L

    2016-01-01

    Severe combined immunodeficiency (SCID) is a fatal childhood disease unless immune reconstitution is performed early in life, with either hematopoietic stem cell transplantation or gene therapy. One of its subtypes is caused by adenosine deaminase (ADA) enzyme deficiency, which leads to the accumulation of toxic metabolites that impair lymphocyte development and function. With the development of polyethylene glycol-conjugated adenosine deaminase (PEG-ADA) enzyme replacement therapy, many ADA-deficient children with SCID who could not receive a hematopoietic stem cell transplantation or gene therapy survived and had longer and healthier lives. We report a 24-year course of treatment in a patient who was diagnosed with ADA deficiency at 4 months of age. The patient was treated with PEG-ADA, which was the only therapy available for him. The patient's plasma ADA level was regularly monitored and the PEG-ADA dose adjusted accordingly. This treatment has resulted in near-normalization of lymphocyte counts, and his clinical course has been associated with only minor to moderate infections. Thus far, he has had no manifestations of autoimmune or lymphoproliferative disorders. This patient is among the longest to be maintained on PEG-ADA enzyme replacement therapy. PMID:26684479

Crossbreds showed lower bone percentage in the carcass than the straightbreds mean, being the difference more evident in G2 and G3. Heterosis for muscle/bone and edible portion/bone ratio was positive in all crossbreeding generations, reaching significance only in G3. Meat of crossbreds was more tender than straightbreds mean when evaluated by panel test or by the Warner-Bratzler Shear, being the retained heterosis 9.39 and -11.36%, respectively. Heterosis for meat juiciness although positive in all crossbreeding generations, was significant only in G3. Comparing the crossbreds versus the straightbreds Charolais or Nellore carcasses, it was observed that the crossbreds showed higher absolute quantity of muscle, but lower muscle/bone ratio than the Charolais and, higher absolute quantity of muscle, bone and fat and higher muscle/bone and edible portion/bone than the Nellore. The carcasses of the crossbreds showed higher muscle and lower bone percentage than the Nellore and, higher fat and lower muscle percentage than the Charolais. Meat of the crossbreds showed lower amount of marbling and similar tenderness to the Charolais, but had more marbling and was more tender than the Nellore meat.

  17. Using the Courts to Shape Medicaid Policy: Olmstead v. L.C. by Zimring and Its Community Integration Legacy.

    Rosenbaum, Sara

    2016-08-01

    In Olmstead v. L.C. by Zimring, the United States Supreme Court addressed the relationship between the Americans with Disabilities Act (ADA), a landmark in US civil rights law, and the Medicaid program. Olmstead holds that qualified individuals with disabilities who are protected by the ADA have the right to receive publicly funded services in community-integrated treatment settings and that medically unnecessary institutionalization violates the ADA. But the Court had to wrestle with the extent to which the ADA requires state Medicaid programs to make deep and structural reforms in how long-term care services are organized, financed, and delivered. From a strictly legal perspective, Olmstead's impact has been limited by the fact that the ADA does not require fundamental alterations in public programs. Despite this fact, Olmstead remains a watershed decision in US disability law that has helped spur transformational changes in how Medicaid addresses community-based long-term care. PMID:27127257

  18. Environmental Services from Agricultural Stormwater Detention Systems in Florida

    Shukla, A.; Shukla, S.; Knowles, J. M.

    2011-12-01

    Agricultural Stormwater Detention Areas (ADAs) commonly exist for the purpose of downstream flood protection in high water table regions of Florida. In addition to flood protection, they are also considered an important Best Management Practice due to their presumed effectiveness in reducing nitrogen (N) and phosphorus (P) loads to the Kissimmee-Lake Okeechobee-Everglades (KLE) ecosystem. The KLE ecosystem has been adversely impacted due to excessive P loads. Despite their presumed water quality effectiveness, limited data exist on actual N and P treatment efficiencies. A study was conducted at two ADAs (ADA 1 and ADA 2) located in two row crop farms to quantify the total N and P treatment efficiencies. Water, N, and P inflow and outflows at both ADAs were monitored for a year. Results from ADA 1 suggested that P treatment efficiency was below zero indicating that the ADA was a source of P rather than a sink. On the other hand, N treatment efficiency was found to be 20%. Mean inflow and outflow N concentrations for ADA 1 were 1.6 and 1.4 mg/l respectively, indicating a 9% reduction. Mean inflow and outflow P concentrations were 0.04 and 0.06 mg/l respectively, showing an increase of 67%. Although ADA 1 was effective in retaining N it was not for P. In contrast to ADA 1, the P treatment efficiency of ADA 2 was positive (20%). Nitrogen treatment efficiency of ADA 2 was 22%. Mean inflow and outflow N concentrations for ADA 2 were 4.0 and 2.0 mg/l respectively, indicating 50% reduction. A reduction of 32% was observed for P concentrations with mean inflow and outflow P concentrations of 0.5 and 0.3 mg/l respectively. No P retention at ADA 1 was mainly due to low P adsorption capacity of the soil. Analysis of surface (0-10 cm) and subsurface (10-20 cm) soil P retention characteristics suggested that ADA 1 had no remaining P storage capacity which resulted in it being a source of P. At ADA 2, a large fraction of the area still had P storage capacity which resulted in

  20. Detection of low-affinity anti-drug antibodies and improved drug tolerance in immunogenicity testing by Octet(®) biolayer interferometry.

    2011-01-25

    We assessed the utility of the FortéBio Octet(®) system for detection of anti-drug antibodies (ADAs) against an investigational therapeutic human IgG1 monoclonal antibody (mAb), CNTO X. To understand the relative merits of this technology, key performance requirements were compared with two popularly accepted ADA detection methods, a step-wise bridging ELISA and a Meso Scale Discovery (MSD) homogeneous (single step binding) bridging ECLIA. When used to detect 13 monoclonal ADAs of varying affinities and one polyclonal ADA, all three methods demonstrated their greatest apparent sensitivity to the polyclonal sample (1, 6, and 130 ng/mL, respectively for ECLIA, ELISA, and Octet). Sensitivity to monoclonal ADAs tended to vary in accordance with their affinities, however, the sensitivity of the Octet method varied much less between ADAs. As a result, the above ranking became reversed such that Octet was the most and ELISA least sensitive for detection of low-affinity ADAs. With regard to drug tolerance, the presence of CNTO X could lead to false-negative assay results, although each method was affected to a different degree, with the Octet method tolerating up to 10 times more drug than the ECLIA method, which in turn tolerated up to 10 times more than the ELISA. Finally, the ECLIA and Octet methods were applied to the bioanalysis of cynomolgus monkey sera from a pre-clinical multiple dose study of CNTO X. Octet indicated 3 positive animals developed ADA as early as day 15 of the dosing phase while drug was present at nearly 1mg/mL. ECLIA detected only one of these, and only in a day 57 recovery sample after drug had cleared from circulation. We conclude that the Octet is a promising platform for detection of lower affinity ADAs and is particularly suitable for ADA detection when drug persists at levels that negatively impact bridging immunoassays.

    2016-07-01

    National, epidemiological data that provide lifetime rates of psychological, physical, and sexual adolescent data abuse (ADA) perpetration and victimization within the same sample of youth are lacking. To address this gap, data from 1058 randomly selected U.S. youth, 14-21 years old, surveyed online in 2011 and/or 2012, were weighted to be nationally representative and analyzed. In addition to reporting prevalence rates, we also examined the overlap of the six types of ADA queried. Results suggested that ADA was commonly reported by both male and female youth. Half (51 %) of female youth and 43 % of male youth reported victimization of at least one of the three types of ADA. Half (50 %) of female youth and 35 % of male youth reported at least one type of ADA perpetration. More male youth reported sexual ADA perpetration than female youth. More female youth reported perpetration of psychological and physical ADA and more reported psychological victimization than male youth. Rates were similar across race and ethnicity, but increased with age. This increase may have been because older youth spent longer time in relationships than younger youth, or perhaps because older youth were developmentally more likely than younger youth to be in abusive relationships. Many youth reported being both perpetrators and victims and/or involved in multiple forms of ADA across their dating history. Together, these findings suggested that interventions should acknowledge that youth may play multiple roles in abusive dyads. Understanding the overlap among ADA within the same as well as across multiple relationships will be invaluable to future interventions aiming to disrupt and prevent ADA. PMID:27098763

  4. Intelligent sensing sensory quality of Chinese rice wine using near infrared spectroscopy and nonlinear tools

    Ouyang, Qin; Chen, Quansheng; Zhao, Jiewen

    2016-02-01

    The approach presented herein reports the application of near infrared (NIR) spectroscopy, in contrast with human sensory panel, as a tool for estimating Chinese rice wine quality; concretely, to achieve the prediction of the overall sensory scores assigned by the trained sensory panel. Back propagation artificial neural network (BPANN) combined with adaptive boosting (AdaBoost) algorithm, namely BP-AdaBoost, as a novel nonlinear algorithm, was proposed in modeling. First, the optimal spectra intervals were selected by synergy interval partial least square (Si-PLS). Then, BP-AdaBoost model based on the optimal spectra intervals was established, called Si-BP-AdaBoost model. These models were optimized by cross validation, and the performance of each final model was evaluated according to correlation coefficient (Rp) and root mean square error of prediction (RMSEP) in prediction set. Si-BP-AdaBoost showed excellent performance in comparison with other models. The best Si-BP-AdaBoost model was achieved with Rp = 0.9180 and RMSEP = 2.23 in the prediction set. It was concluded that NIR spectroscopy combined with Si-BP-AdaBoost was an appropriate method for the prediction of the sensory quality in Chinese rice wine.

  5. Long-term expression of human adenosine deaminase in mice transplanted with retrovirus-infected hematopoietic stem cells

    Long-term stable expression of foreign genetic sequences transferred into hematopoietic stem cells by using retroviral vectors constitutes a relevant model for somatic gene therapy. Such stability of expression may depend on vector design, including the presence or absence of specific sequences within the vector, in combination with the nature and efficiency of infection of the hematopoietic target cells. The authors have previously reported successful transfer of human DNA encoding adenosine deaminase (ADA) into CFU-S (colony-forming unit-spleen) stem cells using simplified recombinant retroviral vectors. Human ADA was expressed in CFU-S-derived spleen colonies at levels near to endogenous enzyme. However, because of the lack of an efficient dominant selectable marker and low recombinant viral titers, stability of long-term expression of human ADA was not examined. They report here the development of an efficient method of infection of hematopoietic stem cells (HSC) without reliance on in vitro selection. Peripheral blood samples of 100% of mice transplanted with HSC infected by this protocol exhibit expression of human ADA 30 days after transplantation. Some mice (6 of 13) continue to express human ADA in all lineages after complete hematopoietic reconstitution (4 months). The use of recombinant retroviral vectors that efficiently transfer human ADA cDNA into HSC leading to stable expression of functional ADA in reconstituted mice, provides an experimental framework for future development of approaches to somatic gene therapy

  6. Regulation of Adenosine Deaminase on Induced Mouse Experimental Autoimmune Uveitis.

    Liang, Dongchun; Zuo, Aijun; Zhao, Ronglan; Shao, Hui; Kaplan, Henry J; Sun, Deming

    2016-03-15

    Adenosine is an important regulator of the immune response, and adenosine deaminase (ADA) inhibits this regulatory effect by converting adenosine into functionally inactive molecules. Studies showed that adenosine receptor agonists can be anti- or proinflammatory. Clarification of the mechanisms that cause these opposing effects should provide a better guide for therapeutic intervention. In this study, we investigated the effect of ADA on the development of experimental autoimmune uveitis (EAU) induced by immunizing EAU-prone mice with a known uveitogenic peptide, IRBP1-20. Our results showed that the effective time to administer a single dose of ADA to suppress induction of EAU was 8-14 d postimmunization, shortly before EAU expression; however, ADA treatment at other time points exacerbated disease. ADA preferentially inhibited Th17 responses, and this effect was γδ T cell dependent. Our results demonstrated that the existing immune status strongly influences the anti- or proinflammatory effects of ADA. Our observations should help to improve the design of ADA- and adenosine receptor-targeted therapies. PMID:26856700

  7. Multiclass Boosting with Adaptive Group-Based kNN and Its Application in Text Categorization

    Lei La

    2012-01-01

    Full Text Available AdaBoost is an excellent committee-based tool for classification. However, its effectiveness and efficiency in multiclass categorization face the challenges from methods based on support vector machine (SVM, neural networks (NN, naïve Bayes, and k-nearest neighbor (kNN. This paper uses a novel multi-class AdaBoost algorithm to avoid reducing the multi-class classification problem to multiple two-class classification problems. This novel method is more effective. In addition, it keeps the accuracy advantage of existing AdaBoost. An adaptive group-based kNN method is proposed in this paper to build more accurate weak classifiers and in this way control the number of basis classifiers in an acceptable range. To further enhance the performance, weak classifiers are combined into a strong classifier through a double iterative weighted way and construct an adaptive group-based kNN boosting algorithm (AGkNN-AdaBoost. We implement AGkNN-AdaBoost in a Chinese text categorization system. Experimental results showed that the classification algorithm proposed in this paper has better performance both in precision and recall than many other text categorization methods including traditional AdaBoost. In addition, the processing speed is significantly enhanced than original AdaBoost and many other classic categorization algorithms.

  8. Development of a capillary electrophoresis method for analyzing adenosine deaminase and purine nucleoside phosphorylase and its application in inhibitor screening.

    Qi, Yanfei; Li, Youxin; Bao, James J

    2016-08-01

    A novel capillary electrophoresis (CE) method was developed for simultaneous analysis of adenosine deaminase (ADA) and purine nucleoside phosphorylase (PNP) in red blood cells (RBCs). The developed method considered and took advantage of the natural conversion from the ADA product, inosine to hypoxanthine. The transformation ratio was introduced for ADA and PNP analysis to obtain more reliable results. After optimizing the enzymatic incubation and electrophoresis separation conditions, the determined activities of ADA and PNP in 12 human RBCs were 0.237-0.833 U/ml and 9.013-10.453 U/ml packed cells, respectively. The analysis of ADA in mice RBCs indicated that there was an apparent activity difference between healthy and hepatoma mice. In addition, the proposed method was also successfully applied in the inhibitor screening from nine traditional Chinese medicines, and data showed that ADA activities were strongly inhibited by Rhizoma Chuanxiong and Angelica sinensis. The inhibition effect of Angelica sinensis on ADA is first reported here and could also inhibit PNP activity. PMID:27173606

  9. The Americans With Disabilities Act: Equal Opportunity for Individuals With Disabilities, in Some Large Businesses, in Some Major Cities, Sometimes . . .

    Eric Allen Harris

    2008-04-01

    Full Text Available On July 26, 1990, the Americans with Disabilities Act (ADA was signed into law by President George H.W. Bush. Congress stated that the purpose of the ADA was “to provide a clear and comprehensive national mandate for the elimination of discrimination against individuals with disabilities.” The first subchapter (Title I of the ADA addresses accommodations for the disabled in the field of employment. President Bush attempted to quash “fears that the ADA is too vague or too costly” by stating that the Act struck a careful balance between the rights of individuals with disabilities and the legitimate interests of businesses. In particular, he noted that Title I of the ADA would become effective for employers with twenty-five or more employees on July 26, 1992, with an extension to employers with fifteen or more employees on July 26, 1994, thus permitting employers adequate time to become acquainted with the ADA. But in fact, the exclusion of employers with fewer than fifteen employees requires only a small percentage of the nation’s employers to ever become acquainted with the ADA at all.

  10. ASYMBOOST-BASED FISHER LINEAR CLASSIFIER FOR FACE RECOGNITION

    Wang Xianji; Ye Xueyi; Li Bin; Li Xin; Zhuang Zhenquan

    2008-01-01

    When using AdaBoost to select discriminant features from some feature space (e.g. Gabor feature space) for face recognition, cascade structure is usually adopted to leverage the asymmetry in the distribution of positive and negative samples. Each node in the cascade structure is a classifier trained by AdaBoost with an asymmetric learning goal of high recognition rate but only moderate low false positive rate. One limitation of AdaBoost arises in the context of skewed example distribution and cascade classifiers: AdaBoost minimizes the classification error, which is not guaranteed to achieve the asymmetric node learning goal. In this paper, we propose to use the asymmetric AdaBoost (Asym-Boost) as a mechanism to address the asymmetric node learning goal. Moreover, the two parts of the selecting features and forming ensemble classifiers are decoupled, both of which occur simultaneously in AsymBoost and AdaBoost. Fisher Linear Discriminant Analysis (FLDA) is used on the selected features to learn a linear discriminant function that maximizes the separability of data among the different classes, which we think can improve the recognition performance. The proposed algorithm is dem onstrated with face recognition using a Gabor based representation on the FERET database. Experimental results show that the proposed algorithm yields better recognition performance than AdaBoost itself.

  11. Reactive electrospinning of composite nanofibers of carboxymethyl chitosan cross-linked by alginate dialdehyde with the aid of polyethylene oxide.

    Zhao, Xiujuan; Chen, Si; Lin, Zifeng; Du, Chang

    2016-09-01

    We have prepared carboxymethyl chitosan-alginate dialdehyde (CMCS-ADA) nanofibers via a reactive electrospinning process with the aid of polyethylene oxide (PEO). The presence of PEO delayed the gelation of CMCS and ADA, thus providing ease of use to adjust the mixing of CMCS-PEO and ADA-PEO blended solution. The mixed solution can be adjusted to come out from the needle before the gel formation or when the gel was just about to form. Defect-free CMCS-ADA-PEO nanofibers with average diameters ranging from 100nm to 900nm were obtained using water as a solvent. The in situ cross-linked CMCS-ADA nanofibers were then obtained following the extraction of water-soluble PEO. After immersion in phosphate-buffered saline (PBS) at a pH of 7.4 for up to 15days, the as-spun CMCS-ADA-PEO composite nanofibers maintained structural integrity, confirming the success of the crosslinking. The PEO-extracted CMCS-ADA nanofibers promoted the adhesion, proliferation and alkaline phosphatase activity of bone marrow stromal cells. PMID:27185120

    Full Text Available Objective: To investigate possible effects of aqueous taxus baccata extract on adenosine deaminase (ADA activity in cancerous and noncancerous human tissues and to clarify mechanism(s of its anticancer potential. Materials and Methods: Cancerous and noncancerous human gastric and colon tissues were used in the study. The extracts were prepared in distilled water. Before and after treatment with the extracts, ADA activities in the tissue homogenates were measured. Results: ADA activity was found to be higher in gastric tissue compared with colon tissue, but no differences were found between ADA activities of cancerous and noncancerous tissues for both as well. In the plant extract studies, it was found that taxus extract significantly inhibited ADA activity both in cancerous and noncancerous gastric and colon tissues. Conclusion: Our results suggest that aqueous extract from taxus baccata inhibits ADA activities in both gastric and colon tissues significantly. It is suggested that in addition to other proposed mechanisms, accumulated adenosine due to the inhibition of ADA enzyme might also play part in the anticancer properties of taxus species.

    Aim: To investigate the effect and mechanism of morphine on purine nucleotide catabolism. Methods: The rat model of morphine dependence and withdrawal and rat C6 glioma cells in culture were used. Concentrations of uric acid in the plasma were measured by the uricase-rap method, adenosine deaminase (ADA) and xan- thine oxidase (XO) in the plasma and tissues were measured by the ADA and XO test kit. RT-PCR and RT-PCR-Southern blotting were used to examine the relative amount of ADA and XO gene transcripts in tissues and C6 cells. Results: (i) the concentration of plasma uric acid in the morphine-administered group was signifi-cantly higher (P<0.05) than the control group; (ii) during morphine administration and withdrawal periods, the ADA and XO concentrations in the plasma increased significantly (P<0.05); (iii) the amount of ADA and XO in the parietal lobe, liver, small intestine, and skeletal muscles of the morphine-administered groups increased, while the level of ADA and XO in those tissues of the withdrawal groups decreased; (iv) the transcripts of the ADA and XO genes in the parietal lobe, liver, small intestine, and skeletal muscles were higher in the morphine-administered group. The expression of the ADA and XO genes in those tissues returned to the control level during morphine withdrawal, with the exception of the skeletal muscles; and (v) the upregulation of the expression of the ADA and XO genes induced by morphine treatment could be reversed by naloxone. Conclusion: The effects of morphine on purine nucleotide metabolism might be an important, new biochemical pharmacological mechanism of morphine action.

  14. 一种组合型的深度学习模型学习率策略%A Combinatory Form Learning Rate Scheduling for Deep Learning Model

    贺昱曜; 李宝奇

    2016-01-01

    A good learning rate scheduling can significantly improve the convergence rate of the deep learning model and reduce the training time. The AdaGrad and AdaDec learning strategies only provide a single form learning rate for all the pa-rameters of the deep learning model. In this paper, AdaMix is proposed. According to the characteristics of the model parame-ters, and a learning rate form which is only based on the current epoch gradient is designed for the connection weights, a power exponential learning rate form is used for the bias. The test re-construction error in the fine-turning phase of the deep learning model is used as the evaluation index. In order to verify the convergence of the deep learning based on different learning rate strategies, Autoencoder, a deep learning model, is trained to re-structure the MNIST database. The experimental results show that Adamix has the lowest reconstruction error and minimum calculation compared with AdaGrad and AdaDec, so the deep learning model can quickly converge by using AdaMix.%一个设计良好的学习率策略可以显著提高深度学习模型的收敛速度,减少模型的训练时间.本文针对AdaGrad 和AdaDec 学习策略只对模型所有参数提供单一学习率方式的问题,根据模型参数的特点,提出了一种组合型学习策略: AdaMix.该策略为连接权重设计了一个仅与当前梯度有关的学习率,为偏置设计使用了幂指数型学习率.利用深度学习模型Autoencoder 对图像数据库MNIST 进行重构,以模型反向微调过程中测试阶段的重构误差作为评价指标,验证几种学习策略对模型收敛性的影响.实验结果表明, AdaMix 比AdaGrad 和AdaDec 的重构误差小并且计算量也低,具有更快的收敛速度.
