    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. Introduction to Image Algebra Ada

    Wilson, Joseph N.

    1991-07-01

    Image Algebra Ada (IAA) is a superset of the Ada programming language designed to support use of the Air Force Armament Laboratory's image algebra in the development of computer vision application programs. The IAA language differs from other computer vision languages is several respects. It is machine independent, and an IAA translator has been implemented in the military standard Ada language. Its image operands and operations can be used to program a range of both low- and high-level vision algorithms. This paper provides an overview of the image algebra constructs supported in IAA and describes the embodiment of these constructs in the IAA extension of Ada. Examples showing the use of IAA for a range of computer vision tasks are given. The design of IAA as a superset of Ada and the implementation of the initial translator in Ada represent critical choices. The authors discuss the reasoning behind these choices as well as the benefits and drawbacks associated with them. Implementation strategies associated with the use of Ada as an implementation language for IAA are also discussed. While one can look on IAA as a program design language (PDL) for specifying Ada programs, it is useful to consider IAA as a separate language superset of Ada. This admits the possibility of directly translating IAA for implementation on special purpose architectures. This paper explores strategies for porting IAA to various architectures and notes the critical language and implementation features for porting to different architectures.

  5. Using Ada: The deeper challenges

    Science.gov (United States)

    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. The AdaBoost Flow

    CERN Document Server

    Lykov, A; Vaninsky, K

    2011-01-01

    We introduce a dynamical system which we call the AdaBoost flow. The flow is defined by a system of ODEs with control. We show how by a suitable choice of control AdaBoost algorithm of Schapire and Freund and arc-gv algorithm of Breiman can be embedded in the AdaBoost flow. We also show how previously studied by Schapire and Singer confidence rated prediction can be obtained from our continuous time approach. We introduce a new continuous time algorithm which we call superBoost and describe its properties. The AdaBoost flow equations coincide with the equations of dynamics of the nonperiodic Toda system written in terms of spectral variables. This establishes a connection between two seemingly unrelated fields of boosting algorithms and classical integrable models. Finally we explain similarity of the AdaBoost flow with Perelman's ideas to control Ricci flow.

  7. 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.

  8. 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

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

    Science.gov (United States)

    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

    Lee, S. Daniel; Allen, Bradley P.

    1990-01-01

    Interest in deploying expert systems in Ada has increased. An Ada based expert system tool is described called ART-Ada, which was built to support research into the language and methodological issues of expert systems in Ada. ART-Ada allows applications of an existing expert system tool called ART-IM (Automated Reasoning Tool for Information Management) to be deployed in various Ada environments. ART-IM, a C-based expert system tool, is used to generate Ada source code which is compiled and linked with an Ada based inference engine to produce an Ada executable image. ART-Ada is being used to implement several expert systems for NASA's Space Station Freedom Program and the U.S. Air Force.

  13. ART/Ada design project, phase 1

    Science.gov (United States)

    1989-01-01

    An Ada-Based Expert System Building Tool Design Research Project was conducted. The goal was to investigate various issues in the context of the design of an Ada-based expert system building tool. An attempt was made to achieve a comprehensive understanding of the potential for embedding expert systems in Ada systems for eventual application in future projects. The current status of the project is described by introducing an operational prototype, ART/Ada. How the project was conducted is explained. The performance of the prototype is analyzed and compared with other related works. Future research directions are suggested.

    Science.gov (United States)

    Hjermstad, Chris

    1986-01-01

    Many essential software functions in the mission critical computer resource application domain depend on floating point arithmetic. Numerically intensive functions associated with the Space Station project, such as emphemeris generation or the implementation of Kalman filters, are likely to employ the floating point facilities of Ada. Paranoia.Ada appears to be a valuabe program to insure that Ada environments and their underlying hardware exhibit the precision and correctness required to satisfy mission computational requirements. As a diagnostic tool, Paranoia.Ada reveals many essential characteristics of an Ada floating point implementation. Equipped with such knowledge, programmers need not tremble before the complex task of floating point computation.

  15. A small evaluation suite for Ada compilers

    Wilke, Randy; Roy, Daniel M.

    1986-01-01

    After completing a small Ada pilot project (OCC simulator) for the Multi Satellite Operations Control Center (MSOCC) at Goddard last year, the use of Ada to develop OCCs was recommended. To help MSOCC transition toward Ada, a suite of about 100 evaluation programs was developed which can be used to assess Ada compilers. These programs compare the overall quality of the compilation system, compare the relative efficiencies of the compilers and the environments in which they work, and compare the size and execution speed of generated machine code. Another goal of the benchmark software was to provide MSOCC system developers with rough timing estimates for the purpose of predicting performance of future systems written in Ada.

    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.

  18. Software engineering and Ada in design

    Science.gov (United States)

    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.

  19. 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.

    Clough, Anne J.

    1986-01-01

    Some of the experience gained from a comprehensive educational program undertaken at The Charles Stark Draper Lab. to introduce the Ada language and to transition modern software engineering technology into the development of Ada and non-Ada applications is described. Initially, a core group, which included manager, engineers and programmers, received training in Ada. An Ada Office was established to assume the major responsibility for training, evaluation, acquisition and benchmarking of tools, and consultation on Ada projects. As a first step in this process, and in-house educational program was undertaken to introduce Ada to the Laboratory. Later, a software engineering course was added to the educational program as the need to address issues spanning the entire software life cycle became evident. Educational efforts to date are summarized, with an emphasis on the educational approach adopted. Finally, lessons learned in administering this program are addressed.

  6. 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.

  7. The OPEN-ADAS Approach to Atomic Data Provision

    International Nuclear Information System (INIS)

    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.

    Adenosine deaminase-1 (ADA1) regulates the concentration of adenosine as the main modulator of oocyte maturation. There is compelling evidence for the association of ADA1 gene polymorphisms with many diseases but the importance of ADA1 polymorphisms in polycystic ovary syndrome (PCOS) has not been studied before. This study investigates serum total ADA activity (tADA), ADA1 and ADA2 isoenzyme activities, and genotype and allele frequencies of G22A and A4223C polymorphisms in healthy and PCOS women. In this case-control study 200 PCOS patients and 200 healthy women were enrolled. Genomic DNA was extracted from whole blood and the PCR-RFLP technique was used to determine the G22A and A4223C variants. The genotype frequencies were calculated and the association between polymorphic genotypes and enzyme activities were determined. tADA activity was significantly lower in the PCOS group compared with the control group (27.76±6.0 vs. 39.63±7.48, respectively). PCOS patients also showed reduced activity of ADA1 and ADA2. PCOS was not associated with G22A polymorphism whereas AA, AC, and CC genotypes of A4223C polymorphism were found distributed differently between the control and the PCOS women where the C allele showed a strong protective role for PCOS (odds ratio=1.876, p=0.033). The present study for the first time showed that lower ADA activity may be involved in pathogenesis of PCOS by maintaining a higher concentration of adenosine affecting follicular growth. As a novel finding, we also showed great differences in genotype distribution and allele frequencies of A4223C polymorphism between groups indicating a protective role for C allele against PCOS. AbbreviationsADA: adenosine deaminase PCOS: polycystic ovary syndrome PCR-RFLP: polymerase chain reaction-restriction fragment length polymorphism tADA: total adenosine deaminase.

  11. Ada and its impact on the scientific user

    International Nuclear Information System (INIS)

    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.)

  12. Accommodating Uncertainty in ADAS Models and Data

    International Nuclear Information System (INIS)

    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

    为解决AdaBoost算法在二分类问题及多分类问题上缺乏共同的理论基础,算法系列的系统性难以得到理论诠释这一问题,首先,从算法思想的层面对AdaBoost算法与最优贝叶斯推理的关系进行了探讨;然后对AdaBoost算法的训练流程及相关参量进行了定量分析;最后从基本不等式定理入手,重点推导了AdaBoost算法由二分类问题向多分类问题延展的理论依据,探讨了AdaBoost算法的本质.总结并证明了AdaBoost算法的2条理论基础:当非负数之和是一个定值时,其差值越大则其乘积越小;非负数的算术平均数大于等于它们的几何平均数.并且分别就二分类问题和多分类问题对AdaBoost算法的应用提出了优化策略.%AdaBoost two-classification and AdaBoost multi-classification lack mutual theory principals, so the unity of AdaBoost algorithm could not be represented theorically. To solve this problem , firstly, the connection of AdaBoost algorithm and Bayes Inference is probed; secondly, the training process and relative parameters of AdaBoost algorithm are analyzed quantitatively; thirdly, with fundamental inequality principals, the extension process of AdaBoost algorithm from two-classification application to multi-classification application is reasoned. Two intrinsic theories are summarized and proved: if the sum of some non-negative numbers is fixed, their product will become smaller when their values difference become greater; arithmetic average of some non-negative numbers is greater than their geometric average. In addition, some improvements to two-classification and multi-classification applications are suggested.

    Vidale, R. F.; Szulewski, P. A.; Weiss, J. B.

    1986-01-01

    The use of timing diagrams is recommended in the design and testing of multi-task Ada programs. By displaying the task states vs. time, timing diagrams can portray the simultaneous threads of data flow and control which characterize tasking programs. This description of the system's dynamic behavior from conception to testing is a necessary adjunct to other graphical techniques, such as structure charts, which essentially give a static view of the system. A series of steps is recommended which incorporates timing diagrams into the design process. Finally, a description is provided of a prototype Ada Execution Analyzer (AEA) which automates the production of timing diagrams from VAX/Ada debugger output.

    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.

    Histone acetylation is an example of covalent modification of chromatin structure that has the potential to regulate gene expression. Gcn5 is a prototypical histone acetyltransferase that associates with the transcriptional coactivator Ada2. In Arabidopsis, two genes encode proteins that resemble yeast ADA2 and share approximately 45% amino acid sequence identity. We previously reported that plants harboring a T-DNA insertion in the ADA2b gene display a dwarf phenotype with developmental defects in several organs. Here we describe T-DNA insertion alleles in the ADA2a gene, which result in no dramatic growth or developmental phenotype. Both ADA2a and ADA2b are expressed in a variety of plant tissues; moreover, expression of ADA2a from a constitutive promoter fails to complement the ada2b-1 mutant phenotype, consistent with the hypothesis that the two proteins have distinct biochemical roles. To further probe the cellular roles of ADA2a and ADA2b, we studied the response of the transcriptional coactivator mutants to abiotic stress. Although ada2b seedlings display hypersensitivity to salt and abscisic acid and altered responses to low temperature stress, the responses of ada2a seedlings to abiotic stress generally parallel those of wildtype plants. Intriguingly, ada2a;ada2b double mutant plants display an intermediate, gcn5-like phenotype, suggesting that ADA2a and ADA2b each work independently with GCN5 to affect genome function in Arabidopsis.

    2015-04-01

    Full Text Available BACKGROUND: Tuberculosis is an important cause of morbidity and mortality in both adults and children, especially in developing countries. For prevention of childhood tuberculosis, BCG vaccination is advocated. Protection is attained 4 - 6 weeks after BCG vaccination a nd is mainly due to cell mediated immunity. After BCG vaccination almost 12 to 15% of neonates do not develop scar but have positive cell mediated immune response. ADA estimation is simple and inexpensive method to assess the cell mediated immunity. OBJECT IVE: To estimate serum ADA levels in children with and without BCG scar, after receiving BCG vaccination. MATERIAL AND METHODS: This prospective observational study was conducted at a tertiary care hospital for a period of 2 years. Babies in post natal ward and infants up to the age of 12 weeks attending well baby clinic for BCG vaccination were included in the study. Serum ADA lev els were estimated before BCG vaccination and 12 - 14 weeks after the vaccination. ADA levels were estimated by colorimetric method. Presence or absence of BCG scar was noted at 12 - 14 weeks of age. RESULTS: A total of 75 babies followed up, of which only 60 babies noted to have scar and in rest 15 babies there was no scar noticed. Twenty unvaccinated babies at 12 weeks of age were included as controls. The Mean ADA levels are significantly elevated after BCG vaccination (34 . 12 ± 3 . 28 U/L in comparison to le vels before vaccination (12 . 55± 2 . 64 U/L with p value 0. 06. CONCLUSION: After BCG vaccination, there is increase in serum ADA levels indicating adequ ate immunity. Increase in ADA levels in children without scar after BCG vaccination may indicate the probability of adequate immunity.

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

    Science.gov (United States)

    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.

    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.

    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.

    Full Text Available Meningitis is inflammation of the meninges (pia, arachnoid and dura mater covering the brain and the spinal cord. ADA is an enzyme in the purine salvage pathway which is found in abundance in active T-lymphocytes. Hence, an attempt was made to estimate the CSF ADA level in patients with suspected meningitis and throw light on its use in differentiating the various types of meningitis. AIMS AND OBJECTIVES To estimate the level of CSF adenosine deaminase level in different types of meningitis. To assess its usefulness in differentiating the various types (bacterial, viral and tuberculous of meningitis. MATERIALS AND METHODS The study was conducted at the medical wards of Govt. Rajaji Hospital, Madurai, a prospective analytical study from a period of April 2012 to September 2012. OBSERVATION AND RESULTS Tuberculous meningitis occurred more in the age group of 21–40 years. Bacterial meningitis was seen mainly in patients < 20 years of age. Viral meningitis was seen in all age groups. CSF ADA level was highest in tuberculous meningitis, the mean value being 24.5 U/L. The mean value of ADA in bacterial meningitis was 4.54 U/L and viral meningitis patients had lowest mean ADA value of 2.65 U/L. CONCLUSION In our study, 50 patients with meningitis admitted in Government Rajaji Hospital from April 2012 to September 2012 were evaluated. Meningitis predominantly affected people in the age group of 20-40 years in our study with a male: female ratio of 1.9:1. Cases of tuberculous meningitis constituted 48% of the study group and bacterial and viral meningitis were 26% each. CSF protein values were higher and sugar values lower in patients with tuberculous and bacterial meningitis. CSF cell counts were higher in patients with bacterial meningitis.

    1989-01-01

    The first phase of a three-phase effort to develop a new graphically oriented specification language which will facilitate the reverse engineering of Ada source code into graphical representations (GRs) as well as the automatic generation of Ada source code is described. A simplified view of the three phases of Graphical Representations for Algorithms, Structure, and Processes for Ada (GRASP/Ada) with respect to three basic classes of GRs is presented. Phase 1 concentrated on the derivation of an algorithmic diagram, the control structure diagram (CSD) (CRO88a) from Ada source code or Ada PDL. Phase 2 includes the generation of architectural and system level diagrams such as structure charts and data flow diagrams and should result in a requirements specification for a graphically oriented language able to support automatic code generation. Phase 3 will concentrate on the development of a prototype to demonstrate the feasibility of this new specification language.

    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.

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.

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

    Science.gov (United States)

    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.

  8. 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.

    Nowadays more and more attraction is drawn by the event-basedimplicit invocation - one of useful architectural patterns, because of its loose couplin g between components in the architecture and reactive integration in software sys tems. Analyzing object-oriented interaction with objects, this paper, based upo n the principle of software architecture, presents an approach on event-based ob j ect model with Ada exception handler. Consequently it is possible for us to impr ove, with adding specific architectural patterns, traditional programming langua ges into architectural description languages.

  10. Monogenic polyarteritis: the lesson of ADA2 deficiency.

    Science.gov (United States)

    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.

    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.

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

  19. Carrier frequency of a nonsense mutation in the adenosine deaminase (ADA) gene implies a high incidence of ADA-deficient severe combined immunodeficiency (SCID) in Somalia and a single, common haplotype indicates common ancestry.

    2007-05-01

    Inherited adenosine deaminase (ADA) deficiency is a rare metabolic disorder that causes immunodeficiency, varying from severe combined immunodeficiency (SCID) in the majority of cases to a less severe form in a small minority of patients. Five patients of Somali origin from four unrelated families, with severe ADA-SCID, were registered in the Greater London area. Patients and their parents were investigated for the nonsense mutation Q3X (ADA c7C>T), two missense mutations K80R (ADA c239A>G) and R142Q (ADA c425G>A), and a TAAA repeat located at the 3' end of an Alu element (AluVpA) positioned 1.1 kb upstream of the ADA transcription start site. All patients were homozygous for the haplotype ADA-7T/ADA-239G/ADA-425G/AluVpA7. Among 207 Somali immigrants to Denmark, the frequency of ADA c7C>T and the maximum likelihood estimate of the frequency of the haplotype ADA-7T/ADA-239G/ADA-425G/AluVpA7 were both 0.012 (carrier frequency 2.4%). Based on the analysis of AluVpA alleles, the ADA c7C/T mutation was estimated to be approximately 7,100 years old. Approximately 1 out of 5 - 10000 Somali children will be born with ADA deficiency due to an ADA c7C/T mutation, although within certain clans the frequency may be significantly higher. ADA-SCID may be a frequent immunodeficiency disorder in Somalia, but will be underdiagnosed due to the prevailing socioeconomic and nutritional deprivation.

    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.

    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.

    Full Text Available Face detection is basic research in computer visual field, it has important application value in the fields of cameras and surveillance and Automatic face recognition. Because traditional algorithm of AdaBoost has the problem that it needs more features and the detection speed is slow when it is used to detect face, so a improved algorithm of AdaBoost is presented. The experiment results shows that compared with traditional algorithm of AdaBoost, lower features are used in the improved algorithm and higher accuracy rate can be get and the speed of detection is improved Significantly.

  14. AdaBoost-based algorithm for network intrusion detection.

    Hu, Weiming; Hu, Wei; Maybank, Steve

    2008-04-01

    Network intrusion detection aims at distinguishing the attacks on the Internet from normal use of the Internet. It is an indispensable part of the information security system. Due to the variety of network behaviors and the rapid development of attack fashions, it is necessary to develop fast machine-learning-based intrusion detection algorithms with high detection rates and low false-alarm rates. In this correspondence, we propose an intrusion detection algorithm based on the AdaBoost algorithm. In the algorithm, decision stumps are used as weak classifiers. The decision rules are provided for both categorical and continuous features. By combining the weak classifiers for continuous features and the weak classifiers for categorical features into a strong classifier, the relations between these two different types of features are handled naturally, without any forced conversions between continuous and categorical features. Adaptable initial weights and a simple strategy for avoiding overfitting are adopted to improve the performance of the algorithm. Experimental results show that our algorithm has low computational complexity and error rates, as compared with algorithms of higher computational complexity, as tested on the benchmark sample data.

    2016-01-01

    Tuberculous and Cryptococcal meningitis are common in HIV patients. A highly specific and sensitive rapid test for diagnosis of Tuberculous meningitis especially in setting of HIV is not available in developing countries where the burden of disease is high. We measured ADA (adenosine deaminase) levels using spectrophotometric method in the CSF of HIV patients with meningitis to differentiate Tuberculous meningitis from meningitis due to other causes. Kruskal-Wallis test was used to compare ADA values between tuberculous meningitis (TBM) and nontuberculous (non-TB) meningitis patients and a receiver-operating characteristic (ROC) analysis curve was drawn from these values. Levels of ADA in the CSF of patients with TBM were significantly higher than those in patients with meningitis due to other causes. CSF ADA level determination with a cut-off value of 6 IU/L was found to be highly specific and fairly sensitive test for the diagnosis of TBM in HIV positive patients. PMID:27144055

    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.

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.

    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.

    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.

    Adult human subcutaneous adipose tissue contains cells with intriguing multilineage developmental plasticity, much like marrow-derived mesenchymal stem cells. Putative stem or progenitor cells from fat have been given many different names in the literature, reflecting an early and evolving consensus regarding their phenotypic characterization. The study reported here used microarrays to evaluate over 170 genes relating to angiogenesis and extracellular matrix in undifferentiated, early-passage human adipose-derived adherent stromal (hADAS) cells isolated from three separate donors. The hADAS populations unanimously transcribed 66% of the screened genes, and 83% were transcribed by at least two of the three populations. The most highly transcribed genes relate to functional groupings such as cell adhesion, matrix proteins, growth factors and receptors, and proteases. The transcriptome of hADAS cells demonstrated by this work reveals many similarities to published profiles of bone marrow mesenchymal stem cells (MSCs). In addition, flow analysis of over 24 hADAS cell surface proteins (n = 7 donors) both confirms and expands on the existing literature and reveals strong intergroup correlation, despite an inconsistent nomenclature and the lack of standardized protocols for cell isolation and culture. Finally, based on flow analysis and reverse transcription polymerase chain reaction studies, our results suggest that hADAS cells do not express several proteins that are implicated as markers of "stemness" in other stem cell populations, including telomerase, CD133, and the membrane transporter ABCG2.

    Severe combined immunodeficiency due to adenosine-deaminase defect (ADA-SCID) is usually deadly in childhood because of severe recurrent infections. When clinical diagnosis is done, permanent damages due to infections or metabolite accumulation are often present. Gene therapy, bone marrow transplantation or enzyme replacement therapy may be effective if started early. The aim of this study was to set-up a robust method suitable for screening with a minimized preparation process and with inexpensive running costs, for diagnosing ADA-SCID by tandem mass spectrometry. ADA-SCID satisfies all the criteria for inclusion in a newborn screening program. We describe a protocol revised to incorporate adenosine and 2-deoxyadenosine testing into an expanded newborn screening program. We assessed the effectiveness of this approach testing dried blood spots from 4 genetically confirmed early-onset and 5 delayed-onset ADA-SCID patients. Reference values were established on 50,000 healthy newborns (deoxyadenosine <0.09μmol/L, adenosine <1.61μmol/L). We also developed a second tier test to distinguish true positives from false positives and improve the positive predictive value of an initial abnormal result. In the first 18 months, the pilot project has identified a newborn with a genetically confirmed defect in adenosine deaminase (ADA) gene. The results show that the method having great simplicity, low cost and low process preparations can be fully applicable to a mass screening program.

    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.

    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.

    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...

    Plant growth and crop production can be greatly affected by common environmental stresses such as drought, high salinity and low temperatures. Gene expression is affected by several abiotic stresses. Stress-inducible genes are regulated by transcription factors and epigenetic mechanisms such as histone modifications. In this Mini-Review, we have explored the role of transcriptional adaptor ADA2b in Arabidopsis responses to abiotic stress. ADA2b is required for the expression of genes involved in abiotic stress either by controlling H3 and H4 acetylation in the case of salt stress or affecting nucleosome occupancy in low temperatures response.

  13. An Ada implementation of the network manager for the advanced information processing system

    1986-01-01

    From an implementation standpoint, the Ada language provided many features which facilitated the data and procedure abstraction process. The language supported a design which was dynamically flexible (despite strong typing), modular, and self-documenting. Adequate training of programmers requires access to an efficient compiler which supports full Ada. When the performance issues for real time processing are finally addressed by more stringent requirements for tasking features and the development of efficient run-time environments for embedded systems, the full power of the language will be realized.

  14. 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).

  15. Implementation of Ada protocols on Mil-STD-1553 B data bus

    Ruhman, Smil; Rosemberg, Flavia

    1986-01-01

    Standardization activity of data communication in avionic systems started in 1968 for the purpose of total system integration and the elimination of heavy wire bundles carrying signals between various subassemblies. The growing complexity of avionic systems is straining the capabilities of MIL-STD-1553 B (first issued in 1973), but a much greater challenge to it is posed by Ada, the standard language adopted for real-time, computer embedded-systems. Hardware implementation of Ada communication protocols in a contention/token bus or token ring network is proposed. However, during the transition period when the current command/response multiplex data bus is still flourishing and the development environment for distributed multi-computer Ada systems is as yet lacking, a temporary accomodation of the standard language with the standard bus could be very useful and even highly desirable. By concentrating all status informtion and decisions at the bus controller, it was found to be possible to construct an elegant and efficient harware impelementation of the Ada protocols at the bus interface. This solution is discussed.

    2016-04-01

    The paper presents the design of a real-time and low-cost embedded system for image acquisition and processing in Advanced Driver Assisted Systems (ADAS). The system adopts a multi-camera architecture to provide a panoramic view of the objects surrounding the vehicle. Fish-eye lenses are used to achieve a large Field of View (FOV). Since they introduce radial distortion of the images projected on the sensors, a real-time algorithm for their correction is also implemented in a pre-processor. An FPGA-based hardware implementation, re-using IP macrocells for several ADAS algorithms, allows for real-time processing of input streams from VGA automotive CMOS cameras.

    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

  6. AdaFF: Adaptive Failure-Handling Framework for Composite Web Services

    Science.gov (United States)

    Kim, Yuna; Lee, Wan Yeon; Kim, Kyong Hoon; Kim, Jong

    In this paper, we propose a novel Web service composition framework which dynamically accommodates various failure recovery requirements. In the proposed framework called Adaptive Failure-handling Framework (AdaFF), failure-handling submodules are prepared during the design of a composite service, and some of them are systematically selected and automatically combined with the composite Web service at service instantiation in accordance with the requirement of individual users. In contrast, existing frameworks cannot adapt the failure-handling behaviors to user's requirements. AdaFF rapidly delivers a composite service supporting the requirement-matched failure handling without manual development, and contributes to a flexible composite Web service design in that service architects never care about failure handling or variable requirements of users. For proof of concept, we implement a prototype system of the AdaFF, which automatically generates a composite service instance with Web Services Business Process Execution Language (WS-BPEL) according to the users' requirement specified in XML format and executes the generated instance on the ActiveBPEL engine.

    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.

    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.

    2016-01-01

    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...

    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.

    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.

    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. The effects of net1 and ada1 mutations on the maintenance of yeast mt genome, chromosomes and plasmids as well as on ce...

  1. 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.

  2. The neuro-glial properties of adipose-derived adult stromal (ADAS cells are not regulated by Notch 1 and are not derived from neural crest lineage.

    Directory of Open Access Journals (Sweden)

    Philip C Wrage

    Full Text Available We investigated whether adipose-derived adult stromal (ADAS are of neural crest origin and the extent to which Notch 1 regulates their growth and differentiation. Mouse ADAS cells cultured in media formulated for neural stem cells (NSC displayed limited capacity for self-renewal, clonogenicity, and neurosphere formation compared to NSC from the subventricular zone in the hippocampus. Although ADAS cells expressed Nestin, GFAP, NSE and Tuj1 in vitro, exposure to NSC differentiation supplements did not induce mature neuronal marker expression. In contrast, in mesenchymal stem cell (MSC media, ADAS cells retained their ability to proliferate and differentiate beyond 20 passages and expressed high levels of Nestin. In neuritizing cocktails, ADAS cells extended processes, downregulated Nestin expression, and displayed depolarization-induced Ca(2+ transients but no spontaneous or evoked neural network activity on Multi-Electrode Arrays. Deletion of Notch 1 in ADAS cell cultures grown in NSC proliferation medium did not significantly alter their proliferative potential in vitro or the differentiation-induced downregulation of Nestin. Co-culture of ADAS cells with fibroblasts that stably expressed the Notch ligand Jagged 1 or overexpression of the Notch intracellular domain (NICD did not alter ADAS cell growth, morphology, or cellular marker expression. ADAS cells did not display robust expression of neural crest transcription factors or genes (Sox, CRABP2, and TH; and lineage tracing analyses using Wnt1-Cre;Rosa26R-lacZ or -EYFP reporter mice confirmed that fewer than 2% of the ADAS cell population derived from a Wnt1-positive population during development. In summary, although media formulations optimized for MSCs or NSCs enable expansion of mouse ADAS cells in vitro, we find no evidence that these cells are of neural crest origin, that they can undergo robust terminal differentiation into functionally mature neurons, and that Notch 1 is likely to be

The line of researchis associated with the developmentof mobile advanced driver assistance system (ADAS. Method.The proposedapproach isbased on the use of driver'sand vehicle behavior ontologies. Current ADAS systems can be divided into two main categories according to the method of implementation: mobile applications, manually installed by the driver from the application stores, and safetyhardware and softwaresystems,integrated into vehicles by manufacturesor in the automotive service centers.Mobile application installed on the smartphone uses the built-in rear and front-facing cameras and sensors to monitor both the road and vehicles ahead, and at the same time the driver in order to prevent traffic collisions. The service consists of components for objects recognition in the images obtained with cameras, and components for traffic situation analysis. Main Results. The driver safety mobile application has been developedfor the use on mobile phones.The mobile phone is mounted on the windshield of a car.In case of dangerous event occurrence, the application engine will make an audible or vibration signal to inform the driver to be concentratedand more vigilant. For example, road obstacles, rear-end and stationary vehicle accidents are the most common accident types.The mobile application detects whether a crash is imminent by computing the ‘Time To Contact’ (TTC taking into account host vehicle speed, relative speed and relative acceleration.If the driver doesn’t maintain safe minimum distance with the car immediately ahead, the mobile application will alert the driver by displaying an attention icon with an audible alert. The dual-camera sensing application is designed to help the drivers increase the trip safety

    The volcano-stratigraphic and geochronologic data presented in this work show that the Tenerife central zone has been occupied during the last 3 Ma by shield or central composite volcanoes which reached more than 3000 m in height. The last volcanic system, the presently active Teide-Pico Viejo Complex began to form approximately 150 ka ago. The first Cañadas Edifice (CE) volcanic activity took place between about 3.5 Ma and 2.7 Ma. The CE-I is formed mainly by basalts, trachybasalts and trachytes. The remains of this phase outcrop in the Cañadas Wall (CW) sectors of La Angostura (3.5-3.0 Ma and 3.0-2.7 Ma), Boca de Tauce (3.0 Ma), and in the bottom of some external radial ravines (3.5 Ma). The position of its main emission center was located in the central part of the CC. The volcano could have reached 3000 m in height. This edifice underwent a partial destruction by failure and flank collapse, forming debris-avalanches during the 2.6-2.3 Ma period. The debris-avalanche deposits can be seen in the most distal zones in the N flank of the CE-I (Tigaiga Breccia). A new volcanic phase, whose deposits overlie the remains of CE-I and the former debris-avalanche deposits, constituted a new volcanic edifice, the CE-II. The dyke directions analysis and the morphological reconstruction suggest that the CE-II center was situated somewhat westward of the CE-I, reaching some 3200 m in height. The CE-II formations are well exposed on the CW, especially at the El Cedro (2.3-2.00 Ma) sector. They are also frequent in the S flank of the edifice (2.25-1.89 Ma) in Tejina (2.5-1.87 Ma) as well as in the Tigaiga massif to the N (2.23 Ma). During the last periods of activity of CE-II, important explosive eruptions took place forming ignimbrites, pyroclastic flows, and fall deposits of trachytic composition. Their ages vary between 1.5 and 1.6 Ma (Adeje ignimbrites, to the W). In the CW, the Upper Ucanca phonolitic Unit (1.4 Ma) could be the last main episode of the CE-II. Afterwards

    Full Text Available Si bien la tradición ha considerado que los poemas homéricos son una fuente determinante en la creación y el desarrollo de la estética griega clásica fundamentada en los ideales de belleza y armonía, también es posible identificar allí una estética de la fealdad y de lo monstruoso, basada en la desmesura y la deformidad. A través de una revisión de la descripción de criaturas como Gorgona, Quimera, Escila, los Cíclopes o el Can Cerbero, es posible elaborar una poética de lo monstruoso que opera en la Ilíada y la Odisea como recurso patémico, pero también como instrumento narrativo.

    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.

    Residents of northern Ada County, Idaho, depend on groundwater for domestic and agricultural uses. The population of this area is growing rapidly and groundwater resources must be understood for future water-resource management. The U.S. Geological Survey, in cooperation with the Idaho Department of Water Resources, used a suite of isotopic and environmental tracers to gain a better understanding of groundwater ages, recharge sources, and flowpaths in northern Ada County. Thirteen wells were sampled between September and October 2009 for field parameters, major anions and cations, nutrients, oxygen and hydrogen isotopes, tritium, radiocarbon, chlorofluorocarbons, and dissolved gasses. Well depths ranged from 30 to 580 feet below land surface. Wells were grouped together based on their depth and geographic location into the following four categories: shallow aquifer, intermediate/deep aquifer, Willow Creek aquifer, and Dry Creek aquifer. Major cations and anions indicated calcium-bicarbonate and sodium-bicarbonate water types in the study area. Oxygen and hydrogen isotopes carried an oxygen-18 excess signature, possibly indicating recharge from evaporated sources or water-rock interactions in the subsurface. Chlorofluorocarbons detected modern (post-1940s) recharge in every well sampled; tritium data indicated modern water (post-1951) in seven, predominantly shallow wells. Nutrient concentrations tended to be greater in wells signaling recent recharge based on groundwater age dating, thus confirming the presence of recent recharge in these wells. Corrected radiocarbon results generated estimated residence times from modern to 5,100 years before present. Residence time tended to increase with depth, as confirmed by all three age-tracers. The disagreement among residence times indicates that samples were well-mixed and that the sampled aquifers contain a mixture of young and old recharge. Due to a lack of data, no conclusions about sources of recharge could be drawn

    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.

    To determine whether there exists an additional pathway of E6 that is independent of direct P53 degradation and whether hADA3, a transcriptional coactivator, is involved in this process. We investigated the association between E6 and hADA3, as well as E6-associated protein (E6AP) and hADA3, in SiHa cells via RNA interference technique. Our results showed that the expression of hADA3 protein was significantly increased, cellular proliferation was decreased and apoptotic rate was increased in SiHa cells treated by E6 siRNA and E6AP siRNA respectively. Our results suggested that oncoprotein E6 inhibits hADA3 in cervical cancer cells and this process is E6AP-dependent.

    Directory of Open Access Journals (Sweden)

    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.

    This paper presents a non-intrusive approach for monitoring driver drowsiness using the fusion of several optimized indicators based on driver physical and driving performance measures, obtained from ADAS (Advanced Driver Assistant Systems) in simulated conditions. The paper is focused on real-time drowsiness detection technology rather than on long-term sleep/awake regulation prediction technology. We have developed our own vision system in order to obtain robust and optimized driver indicators able to be used in simulators and future real environments. These indicators are principally based on driver physical and driving performance skills. The fusion of several indicators, proposed in the literature, is evaluated using a neural network and a stochastic optimization method to obtain the best combination. We propose a new method for ground-truth generation based on a supervised Karolinska Sleepiness Scale (KSS). An extensive evaluation of indicators, derived from trials over a third generation simulator with several test subjects during different driving sessions, was performed. The main conclusions about the performance of single indicators and the best combinations of them are included, as well as the future works derived from this study.

    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.

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

    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.

    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.

    1989-03-01

    The success of the Strategic Defense Initiative depends directly on significant advances in both computer hardware and software development technologies. Parallel architectures and the Ada programming language have advantages that make them candidates for use in SDI command and control computer systems. This thesis examines those advantages in the context of an SDI-type application: implementation of a Kalman-filter tracking system. This research consists of three parts. The first is a set of software engineering guidelines developed for use in creating parallel designs suitable for implementation in Ada. These guidelines cover the design process from initial problem analysis to final detailed design. Methods of problem decomposition are discussed, as are language partitioning strategies. Justification is provided for using the Ada task construct for process boundaries, and Ada multitasking design issues are reviewed. A parallel software design methodology is also described.

    Syzygium cumini (S. cumini) is a plant known for its antidiabetic properties. The aim of this study was to evaluate the effect of Sc aqueous leaf extract (ASc) on adenosine deaminase (ADA) activity in erythrocytes (RBCs) exposed to high glucose concentrations (30 mM) in vitro. We also investigated the effects of the main phenolic compounds found in ASc (gallic acid, rutin, and chlorogenic acid) and the effects of insulin, caffeine, and dipyridamole, which are substances involved in the adenosine metabolism, on ADA activity in vitro. Blood samples were obtained from healthy volunteers and a suspension of RBCs was used for the determination of ADA activity. The results showed that: (1) the effect of ASc on ADA activity was more significant than the combination of phenolic compounds; (2) insulin, caffeine, or dipyridamole prevented high glucose increase of ADA activity at doses as low as 50 μU/mL, 25 μM, and 1 μM, respectively; (3) the inhibitory effect caused by ASc on erythrocyte ADA activity remained practically the same after the combination of the extract with insulin or caffeine; (4) when RBCs were exposed to ASc plus dipyridamole, this chemical attenuated the effect of ASc on ADA activity, suggesting an antagonism or a competition with ASc by the same site of action. Therefore, ASc was more effective in preventing the increase in ADA activity than phenolic compounds, suggesting that ASc may collaborate to improve endothelial dysfunction, antioxidant, anti-inflammatory, and antithrombotic properties of adenosine by affecting its metabolism. The results of this study help to provide evidence of the empirically supported benefits of the use of S. cumini in diabetes. PMID:24407852

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

    Directory of Open Access Journals (Sweden)

    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.

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

    International Nuclear Information System (INIS)

    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

    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.

    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.

    2007-01-01

    Spoken dialogue systems have been increasingly employed to provide ubiquitous automated access via telephone to information and services for the non-Internet-connected public. In the health care context, dialogue systems have been successfully applied. Nevertheless, speech-based technology is not easy to implement because it requires a considerable development investment. The advent of VoiceXML for voice applications contributed to reduce the proliferation of incompatible dialogue interpreters, but introduced new complexity. As a response to these issues, we designed an architecture for dialogue representation and interpretation, AdaRTE, which allows developers to layout dialogue interactions through a high level formalism that offers both declarative and procedural features. AdaRTE aim is to provide a ground for deploying complex and adaptable dialogues whilst allows the experimentation and incremental adoption of innovative speech technologies. It provides the dynamic behavior of Augmented Transition Networks and enables the generation of different backends formats such as VoiceXML. It is especially targeted to the health care context, where a framework for easy dialogue deployment could reduce the barrier for a more widespread adoption of dialogue systems. PMID:17911878

    2005-01-01

    Locating multi-view faces in images with a complex background remains a challenging problem. In this paper, an integrated method for real-time multi-view face detection and pose estimation is presented. A simple-to-complex and coarse-to-fine view-based detector architecture has been designed to detect multi-view faces and estimate their poses efficiently. Both the pose estimators and the view-based face/nonface detectors are trained by a cost-sensitive AdaBoost algorithm to improve the generalization ability. Experimental results show that the proposed multi-view face detector, which can be constructed easily, gives more robust face detection and pose estimation and has a faster real-time detection speed compared with other conventional methods.

    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

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

    Directory of Open Access Journals (Sweden)

    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.

    Mackin, Michael A.

    1995-01-01

    This document describes the software designed to provide communication between control computers in the NASA Lewis Research Center Electrical Power System Testbed using MIL-STD-1553B. The software drivers are coded in the Ada programming language and were developed on a MSDOS-based computer workstation. The Electrical Power System (EPS) Testbed is a reduced-scale prototype space station electrical power system. The power system manages and distributes electrical power from the sources (batteries or photovoltaic arrays) to the end-user loads. The electrical system primary operates at 120 volts DC, and the secondary system operates at 28 volts DC. The devices which direct the flow of electrical power are controlled by a network of six control computers. Data and control messages are passed between the computers using the MIL-STD-1553B network. One of the computers, the Power Management Controller (PMC), controls the primary power distribution and another, the Load Management Controller (LMC), controls the secondary power distribution. Each of these computers communicates with two other computers which act as subsidiary controllers. These subsidiary controllers are, in turn, connected to the devices which directly control the flow of electrical power.

  6. Early breast cancer detection with digital mammograms using Haar-like features and AdaBoost algorithm

    The current computer-aided detection (CAD) methods are not sufficiently accurate in detecting masses, especially in dense breasts and/or small masses (typically at their early stages). A small mass may not be perceived when it is small and/or homogeneous with surrounding tissues. Possible reasons for the limited performance of existing CAD methods are lack of multiscale analysis and unification of variant masses. The speed of CAD analysis is important for field applications. We propose a new CAD model for mass detection, which extracts simple Haar-like features for fast detection, uses AdaBoost approach for feature selection and classifier training, applies cascading classifiers for reduction of false positives, and utilizes multiscale detection for variant sizes of masses. In addition to Haar features, local binary pattern (LBP) and histograms of oriented gradient (HOG) are extracted and applied to mass detection. The performance of a CAD system can be measured with true positive rate (TPR) and false positives per image (FPI). We are collecting our own digital mammograms for the proposed research. The proposed CAD model will be initially demonstrated with mass detection including architecture distortion.

    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.

    The ADA and the EASD recently published a consensus statement for the medical management of hyperglycaemia in patients with type 2 diabetes. The authors advocate initial treatment with metformin monotherapy and lifestyle modification, followed by addition of basal insulin or a sulfonylurea if glycaemic goals are not met (tier 1 recommendations). All other glucose-lowering therapies are relegated to a secondary (tier 2) status and only recommended for selected clinical settings. In our view, this algorithm does not offer physicians and patients the appropriate selection of options to individualise and optimise care with a view to sustained control of blood glucose and reduction both of diabetes complications and cardiovascular risk. This paper critically assesses the basis of the ADA/EASD algorithm and the resulting tiers of treatment options. PMID:20352408

    Full Text Available A new section including nine stratigraphically superposed microvertebrate fossil localities from the Calatayud-Montalbán basin (Spain is presented. The Cañada localities and the small mammal assemblages are described, allowing a biostratigraphical correlation with the lower Vallesian from the nearby section of Nombrevilla. The results of this work are important because they help to improve the time resolution of the lower Vallesian faunal record from the Daroca area and to precise their relative biostratigraphical position. In addition, the upper part of the Cañada section includes two Turolian faunas, increasing the poor record from this age in the Calatayud-Montalbán basin.

    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.

    2009-06-01

    This study reviews and analyzes the content of dental school oaths taken by students in the United States, Canada, and Puerto Rico in 2006. Each oath was qualitatively reviewed to determine its consistency with each of the five principles set forth in the American Dental Association (ADA)'s Principles of Ethics and Code of Professional Conduct. Fifty-eight oaths were received from sixty-one of sixty-six schools in response to information requests regarding use of oaths and manner of administration. Of these, thirty-nine employ one oath, administered at either graduation or ceremonies marking transition to clinical training; twelve employ an oath at both occasions, with five repeating the same oath; and ten have no formal oaths. Eighteen oaths follow the wording of "The Dentist's Pledge," nine follow the "Oath to the Profession/Professional Pledge," three follow the Modern Hippocratic Oath, and twenty-eight are idiosyncratic. All five of the ADA principles (autonomy, nonmaleficence, beneficence, justice, and veracity) are addressed in thirteen oaths, four principles in nine oaths, and three or fewer principles in thirty-six oaths. Eleven make reference to care for the underserved. As oath-taking is an opportunity to instill and reinforce to students dentistry's most important ethical obligations, recommendations are offered to make the content more meaningful and comprehensive.

    Expression of the adenovirus E1A protein in the simple eukaryote Saccharomyces cerevisiae inhibits growth. We tested four regions of E1A that alter growth and transcription in mammalian cells for their effects in yeast when expressed as fusions to the Gal4p DNA binding domain. Expression of the N-terminal/conserved region (CR) 1 or CR3, but not of the CR2 or the C-terminal portion of E1A, inhibited yeast growth. Growth inhibition was relieved by deletion of the genes encoding the yGcn5p, Ngg1p, or Spt7p components of the SAGA transcriptional regulatory complex, but not the Ahc1p component of the related ADA complex, indicating that the N-terminal/CR1 and CR3 regions of E1A target the SAGA complex independently. Expression of the pCAF acetyltransferase, a mammalian homologue of yGcn5p, also suppressed growth inhibition by either portion of E1A. Furthermore, the N-terminal 29 residues and the CR3 portion of E1A interacted independently with yGcn5p and pCAF in vitro. Thus, two separate regions of E1A target the yGcn5p component of the SAGA transcriptional activation complex. A subregion of the N-terminal/CR1 fragment spanning residues 30-69 within CR1 also inhibited yeast growth in a SAGA-dependent fashion. However, this region did not interact with yGcn5p or pCAF, suggesting that it makes a third contact with another SAGA component. Our results provide a new model system to elucidate mechanisms by which E1A and the SAGA complex regulate transcription and growth. PMID:12070146

    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.

    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.

    2008-07-01

    Full Text Available Abstract Background Recent clinical trials reported conflicting results on the reduction of new-onset diabetes using RAS blocking agents. Therefore the role of these agents in preventing diabetes is still not well defined. Ramipril is an ACE inhibitor (ACEi, that has been shown to reduce cardiovascular events in high risk patients and post-hoc analyses of the HOPE trial have provided evidence for its beneficial action in the prevention of diabetes. Methods The ADaPT investigation ("ACE inhibitor-based versus diuretic-based antihypertensive primary treatment in patients with pre-diabetes" is a 4-year open, prospective, parallel group phase IV study. It compares an antihypertensive treatment regimen based on ramipril versus a treatment based on diuretics or betablockers. The primary evaluation criterion is the first manifestation of type 2 diabetes. The study is conducted in primary care to allow the broadest possible application of its results. The present article provides an outline of the rationale, the design and baseline characteristics of AdaPT and compares these to previous studies including ASCOT-BLPA, VALUE and DREAM. Results Until March 2006 a total of 2,015 patients in 150 general practices (general physicians and internists throughout Germany were enrolled. The average age of patients enrolled was 67.1 ± 10.3 years, with 47% being male and a BMI of 29.9 ± 5.0 kg/m2. Dyslipidemia was present in 56.5%. 37.8% reported a family history of diabetes, 57.8% were previously diagnosed with hypertension (usually long standing. The HbA1c value at baseline was 5.6 %. Compared to the DREAM study patients were older, had more frequently hypertension and patients with cardiovascular disease were not excluded. Conclusion Comparing the ADaPT design and baseline data to previous randomized controlled trial it can be acknowledged that AdaPT included patients with a high risk for diabetes development. Results are expected to be available in 2010. Data

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.

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.

    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.

    Full Text Available Neste trabalho, apresenta-se e se discute um estudo experimental sobre o comportamento estrutural de vigas de concreto reforçadas com bambu. Ensaiaram-se dez vigas de concreto armado, sendo oito vigas armadas longitudinalmente com varas de bambu Dendrocalamus giganteus e duas vigas de referência, armadas com barras de aço. Duas variáveis foram estudadas: a taxa de armadura longitudinal (1,6 e 3,2% e a relação área/perímetro das varas de bambu (0,25 e 0,33 cm. Para cada combinação de variáveis foram confeccionadas duas vigas. Curvas força vs. deslocamento e força vs. deformação dos materiais são apresentadas e discutidas. Constatou-se que o comportamento estrutural das vigas de concreto reforçadas com bambu segue a teoria de flexão de Bernoulli-Kirchoff, sendo possível a aplicação dos procedimentos usuais de dimensionamento do concreto armado no projeto desses elementos. Observou-se, também, que a capacidade de carga dessas vigas se assemelha à das vigas de aço; contudo, estas são mais rígidas que aquelas.In this paper, an experimental study about bamboo reinforced concrete beams is presented and discussed. Ten reinforced concrete beams were tested, where eight of them were reinforced with Dendrocalamus giganteus bamboo-splint and two reference beams were reinforced with steel bars. Two factors were studied: the longitudinal reinforcement ratio (1.6 and 3.2% and the area/perimeter ratio of the bamboo-splint (0.25 and 0.33 cm. For each factor combination, two beams were cast. Force vs. displacement and force vs. strain curves are presented and discussed. It was found out that the structural behaviour of bamboo-concrete beams follow the Bernoulli-Kirchoff bending theory. Therefore, the usual design procedures of reinforced concrete can be used to design the bamboo-concrete beams. The load capacity of the bamboo-concrete beams is almost the same as that of reinforced with steel; nevertheless, are more stiffer than those

    Full Text Available Uma das deficiências do bambu reforçando vigas de concreto armado está relacionada com deslocamentos relativos entre os dois materiais. A investigação aqui reportada teve como objetivo avaliar experimentalmente a possibilidade de se melhorar o trabalho conjunto bambu-concreto, através do cravejamento de pinos nas ripas de bambu usadas como reforço. Para tanto, oito vigas de concreto foram ensaiadas, das quais seis foram reforçadas com ripas de bambu Dendrocalamus giganteus Munro cravejadas de pinos e duas armadas com ripas de bambu sem a presença dos pinos, como referência. Usaram-se dois tipos de pino: de aço ou de bambu, em número de dois, três ou quatro pinos entre nós. Curvas força-deslocamento e força-deformação dos materiais são apresentadas e discutidas, em que os resultados mostraram que a cravação dos pinos produziu um aumento de rigidez das vigas; contudo, o furo feito para colocação do pino reduziu localmente a seção transversal da ripa de bambu e, consequentemente, a resistência última das vigas. Finalmente, resultados similares foram obtidos em vigas reforçadas com pino de aço ou de bambu.One drawback of bamboo as concrete reinforcement beams is the relative displacement between the two materials. The research reported in this paper aimed to experimentally investigate the improvement of bamboo-concrete-bond by means of nailing. Eight concrete beams were tested, six of them reinforced with Dendrocalamus giganteus Munro nailed bamboo-splints and two reference beams, reinforced with bamboo-splints without pins. Steel pins or bamboo pins were used. Two, three and four pins were nailed between bamboo nodes. Load-displacement and load-strain curves are presented and discussed. The results showed that the pins improved the beam stiffness; nevertheless, they reduced locally the transversal section of the bamboo splint and, consequently, the ultimate load. Finally, similar results were showed by beams reinforced

    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

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.

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.

    现有的Web主题分类算法一般基于单一模型构建或者仅仅把多个单一模型简单叠加进行决策。针对该问题,提出一种基于多分类器集成的改进AdaBoost算法的Web主题分类方法。算法先采用VIPS算法获取页面分块并获取其视觉特征和文本特征,根据每一类特征的维度分别训练弱分类器,然后计算其对应的错误率,修改错误判别的拒绝策略,从而针对不同特征产生相应的最优分类器,最后对两类最优分类器级联决策。实验结果表明,该方法能提高AdaBoost算法对复杂Web主题信息的分类准确率,同时也为Web主题分类领域的研究提供一种新的方案。%Current Web topic classification algorithms are generally constructed based on single model or merely superimpose the multiple single model for decision-making.In light of the problem, we propose a new Web topic classification method which is based on the modified multi-classifier integration AdaBoost algorithm .Firstly, the method uses VIPS algorithm to acquire page blocks as well as their visual and text features, and trains weak classifier on the basis of the dimension of each feature; then, the algorithm calculates its corresponding error rate and modifies the refusal strategies of error discrimination , so that generates the corresponding optimal classifier for different features ;finally it performs cascading decision-making on two kind of optimal classifiers .Experimental results demonstrate that the method can improve the classification precision of AdaBoost on complex Web topic information , and at the same time it also provides a kind of new scheme for research on Web topic classification field .

    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

Appropriate thermal properties of roofing materials tend to improve the thermal comfort in the inner ambient. Nonasbestos fiber-cement roofing components reinforced with cellulose pulp from sisal (Agave sisalana were produced by slurry and dewatering techniques, with an optional addition of polypropylene fibers. Nonasbestos tiles were evaluated and compared with commercially available asbestos-cement sheets and ceramic tiles (frequently chosen as roofing materials for animal housing. Thermal conductivity and thermal diffusivity of tiles were determined by the parallel hot-wire method, along with the evaluation of the downside surface temperature. Cement-based components reinforced with sisal pulp presented better thermal performance at room temperature (25ºC, while those reinforced with sisal pulp added by polypropylene fibers presented better thermal performance at 60ºC. Non-asbestos cement tiles provided more efficient protection against radiation than asbestos corrugated sheets.O telhado fornece a principal proteção contra a radiação solar direta em galpões para animais. Propriedades térmicas apropriadas dos materiais contribuem para o melhor conforto térmico no interior das construções.

    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).

    Full Text Available A deficiência transversa da maxila é um fator agravante e complicador do tratamento ortodôntico em adultos. Sua correção ainda gera dúvidas e controvérsias entre clínicos e pesquisadores. O objetivo deste trabalho foi analisar e discutir fatores determinantes para o planejamento da expansão maxilar em adultos e adolescentes com maturação esquelética avançada. Ausências dentárias múltiplas, grandes inclinações dentoalveolares para vestibular, recessão gengival, perda óssea alveolar e mobilidade dos dentes posterossuperiores contraindicam a realização de expansão rápida da maxila em indivíduos adultos ou com maturação esquelética avançada. No entanto, esses fatores não devem ser considerados isoladamente para a escolha do método de expansão palatal nesses pacientes. Nessas situações, a Expansão Rápida da Maxila Assistida Cirurgicamente (ERMAC pode ser uma opção, entretanto, a escolha por essa técnica deve basear-se principalmente na idade do paciente, no grau de maturação esquelética, na localização da deficiência transversa da maxila e nas estruturas anatômicas que oferecem maior resistência à expansão maxilar. O Hyrax é o aparelho mais indicado para indivíduos que vão se submeter à ERMAC.The transverse maxillary deficiency is a complication factor in adults' orthodontic treatment. Its correction still generates doubts and controversies between clinicians and researchers. The aim of this paper is to discuss the determinative factors in planning maxillary expansion in adults and adolescents with advanced skeletal maturation. Multiple dental absences, several dentoalveolar buccal inclination, gingival recession, alveolar bone loss and mobility of posterosuperior teeth contraindicate the rapid maxillary expansion in adults or patients with advanced skeletal maturation. However, these factors should not be considered separately when choosing the method for palatal expansion in adults. In these

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.

MÉTODOS: Equações e limites de referência foram derivados em 270 homens e 373 mulheres, habitantes de oito cidades brasileiras, por espirômetro. A idade variou de 20 a 85 anos nas mulheres e 26 a 86 anos nos homens. Os exames seguiram as normas recomendadas pela Sociedade Brasileira de Pneumologia e Tisiologia. Os limites inferiores foram derivados pela análise do 5º percentil dos resíduos. RESULTADOS: Os valores previstos para capacidade vital forçada (CVF, volume expiratório forçado no primeiro segundo (VEF1 e para as relações VEF1/CVF e VEF1/volume expiratório forçado nos primeiros seis segundos (VEF6 se ajustaram melhor em regressões lineares. Os fluxos ajustaram-se melhor em equações logarítmicas. Em ambos os sexos, maiores estaturas resultaram em menores valores para as relações VEF1/CVF, VEF1/VEF6 e fluxos/CVF. Os valores de referência do VEF1 e da CVF, no presente estudo, foram maiores do que aqueles derivados para adultos brasileiros em 1992. CONCLUSÃO: Novos valores previstos para a espirometria forçada foram obtidos em uma amostra da população brasileira de raça branca. Os valores são maiores do que os obtidos em 1992, provavelmente em decorrência de fatores técnicos.OBJECTIVE: To describe spirometric reference equations for healthy Brazilian adults who have never smoked and to compare the predicted values with those derived in 1992.

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.

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.

    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.

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 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.

Neste trabalho, inicialmente é apresentada uma revisão dos princípios da técnica juntamente com uma discussão sobre suas vantagens e atuais limitações. A performance da técnica é comparada com a dos métodos clássicos na detecção de afecções respiratórias. As principais aplicações clínicas reportadas anteriormente na literatura, incluindo a avaliação da mecânica ventilatória infantil, estudos em neonatos, monitorização de pacientes sob ventilação mecânica, medicina ocupacional e avaliação de distúrbios no sono, são revisadas e discutidas. Com base na revisão efetuada e nos resultados obtidos em estudos efetuados em laboratório, os autores concluem que a TOF pode contribuir para um exame mais detalhado, assim como para facilitar a realização de testes de função pulmonar em condições nas quais as técnicas tradicionais não são adequadas.Requesting passive cooperation from the patient and supplying new parameters for the analysis of the ventilatory mechanics, the forced oscillations technique (FOT has complementary characteristics to the classical methods of lung evaluation.

    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

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.

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

    Science.gov (United States)

    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.

    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.

I was left with a very strong impression this morning about the large degree of integration that has been achieved in the science-based stockpile stewardship program in the last year. When Vic Reis convened this program last February, many of you same people from Energy Research, Defense Programs, and the external community were there. We talked about areas of investments: in credible capability and industrial interaction, the impact on the research community, and so on. The product was the published quality function deployment chart. The activities on the chart were important, but they did not have coherence. In listening to the presentations this morning, particularly the last four, I hear a high degree of coherence and integration, which is very pleasing.

  9. Desahuciando inmigrantes: una etnografía en una comunidad dañada

    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.

    Full Text Available INTRODUCCIÓN: debido a los resultados clínicos no satisfactorios con instrumentaciones posteriores en los casos de tumor vertebral y a las carencias económicas de nuestros pacientes para adquirir los sistemas disponibles en el mercado, fue diseñada una prótesis de cuerpo vertebral para estabilizar la columna después de una corpectomía. OBJETIVO: describir las características estructurales y funcionales de la prótesis JR, las pruebas biomecánicas en cadáver y la técnica quirúrgica en el paciente. MÉTODOS: primeramente fue realizado un estudio anatómico detallado de los cuerpos vertebrales. Se obtuvo el diseño de un dispositivo modular, anatómico y expandible. Sus componentes una vez ensamblados hacen un implante con función dual de jaula y placa lateral expandibles. Posteriormente se efectuó un ensayo de propiedades biomecánicas en cadáver y se implantó un dispositivo en un paciente con metástasis en cuerpo vertebral. RESULTADOS: las radiografías que le fueron tomadas al cadáver, posterior a la colocación del implante, no mostraron pérdida de la fijación. Al levantar el cadáver se generaron momentos de flexión en sentido lateral con brazos de palanca de 80 cm de largo, por lo que la prótesis fue demandada en su punto más vulnerable con una fuerza de aproximadamente 588 N. Con la rotación, flexión y extensión forzadas, la estabilidad se conservó y no se visualizó movimiento del implante. Se colocó el dispositivo en una mujer de 50 años con cáncer metastásico de tiroides que afectaba L3. El dolor mejoró en el postoperatorio inmediato, así como su función motora que le permitió caminar con una columna estable e indolora por siete años. No se observó fracaso del implante. CONCLUSIÓN: la función dual de jaula y placa integrada en la prótesis de cuerpo vertebral establece una ventaja mecánica comparada con la función de la jaula y de la placa separadamente, ya que el diseño de la prótesis permite

However, the impact of the circadian timing system as well as contributions of specific sleep properties to this beneficial effect remains largely unexplored.

    Full Text Available Traditional Çanakkale ceramics is a kind of folk art which originated from the turkification of Anatolia and the cultural synthesis between the Aegean islands. It is well-known that it had its genesis in the influential Seljukian art. It has similarities to the Byzantine ceramics as clear from the usage of the materials, shaping, the decorative features and the like. Although art historians adopt a sceptic approach to this situation, similarities are eminent for a ceramist. The beginning of Çanakkale ceramics can be traced back to Akköy ceramics. Lesbos’s and Akköy’s white slip decoration share similarities, which forms a natural bond between Lesvos and Akköy for Çanakkale. Wars and war-induced migrations caused cultural exchanges, which also affected coastal settlements in Western Anatolia and the Greek islands. Till the productions and widespread use of the plastic materials, the bond between agricultural and commercial activities and ceramic products is important. This bond is an integral part of the ongoing interaction between the two shores. The ceramics of this interaction have survived as witnesses of the similarities till now.

    Full Text Available Abstract Background Previous randomized controlled trials demonstrated a protective effect of renin angiotensin system blocking agents for the development of type-2 diabetes in patients with pre-diabetes. However, there are no real-world data available to illustrate the relevance for clinical practice. Methods Open, prospective, parallel group study comparing patients with an ACE inhibitor versus a diuretic based treatment. The principal aim was to document the first manifestation of type-2 diabetes in either group. Results A total of 2,011 patients were enrolled (mean age 69.1 ± 10.3 years; 51.6% female. 1,507 patients were available for the per-protocol analysis (1,029 ramipril, 478 diuretic group. New-onset diabetes was less frequent in the ramipril than in the diuretic group over 4 years. Differences were statistically different at a median duration of 3 years (24.4% vs 29.5%; p Conclusions Ramipril treatment is preferable over diuretic based treatment regimens for the treatment of hypertension in pre-diabetic patients, because new-onset diabetes is delayed.

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

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.

  1. Assessment of soil and water contaminants from selected locations in and near the Idaho Army National Guard Orchard Training Area, Ada County, Idaho, 2001-2003

    Parliman, D.J.

    2004-01-01

    In 2001, the National Guard Bureau and the U.S. Geological Survey began a project to compile hydrogeologic data and determine presence or absence of soil, surface-water, and ground-water contamination at the Idaho Army National Guard Orchard Training Area in southwestern Idaho. Between June 2002 and April 2003, a total of 114 soil, surface-water, ground-water, precipitation, or dust samples were collected from 68 sample sites (65 different locations) in the Orchard Training Area (OTA) or along the vehicle corridor to the OTA. Soil and water samples were analyzed for concentrations of selected total trace metals, major ions, nutrients, explosive compounds, semivolatile organics, and petroleum hydrocarbons. Water samples also were analyzed for concentrations of selected dissolved trace metals and major ions. Distinguishing naturally occurring large concentrations of trace metals, major ions, and nutrients from contamination related to land and water uses at the OTA was difficult. There were no historical analyses for this area to compare with modern data, and although samples were collected from 65 locations in and near the OTA, sampled areas represented only a small part of the complex OTA land-use areas and soil types. For naturally occurring compounds, several assumptions were made?anomalously large concentrations, when tied to known land uses, may indicate presence of contamination; naturally occurring concentrations cannot be separated from contamination concentrations in mid- and lower ranges of data; and smallest concentrations may represent the lowest naturally occurring range of concentrations and (or) the absence of contaminants related to land and water uses. Presence of explosive, semivolatile organic (SVOC), and petroleum hydrocarbon compounds in samples indicates contamination from land and water uses. In areas along the vehicle corridor and major access roads within the OTA, most trace metal, major ion, and nutrient concentrations in soil samples were not in the upper 10th percentile of data, but concentrations of 25 metals, ions, or nutrients were in the upper 10th percentile in a puddle sample near the heavy equipment maneuvering area, MPRC-H. The largest concentrations of tin, ammonia, and nitrite plus nitrate (as nitrogen) in water from the OTA were detected in a sample from this puddle. Petroleum hydrocarbons were the most common contaminant, detected in all soil and surface-water samples. An SVOC, bis (2-ethylhexyl) phthalate, a plasticizer, was detected at a site along the vehicle corridor. In Maneuver Areas within the OTA, many soil samples contained at least one trace metal, major ion, or nutrient in the upper 10th percentile of data, and the largest concentrations of cobalt, iron, mercury, titanium, sodium, ammonia, or total phosphorus were detected in 6 of 13 soil samples outside the Tadpole Lake area. The largest concentrations of aluminum, arsenic, beryllium, nickel, selenium, silver, strontium, thallium, vanadium, chloride, potassium, sulfate, and nitrite plus nitrate were detected in soil samples from the Tadpole Lake area. Water from Tadpole Lake contained the largest total concentrations of 19 trace metals, 4 major ions, and 1 nutrient. Petroleum hydrocarbons were detected in 5 soil samples and water from Tadpole Lake. SVOCs related to combustion of fuel or plasticizers were detected in 1 soil sample. Explosive compounds were detected in 1 precipitation sample.In the Impact Area within the OTA, most soil samples contained at least one trace metal, major ion, or nutrient in the upper 10th percentile of data, and the largest concentrations of barium, chromium, copper, manganese, lead, or orthophosphate were detected in 6 of the 18 soil samples. Petroleum hydrocarbons were detected in 4 soil samples, SVOCs in 6 samples, and explosive compounds in 4 samples. In the mobilization and training equipment site (MATES) compound adjacent to the OTA, all soil and water samples contained at lea

    Full Text Available A cardiomiopatia dilatada caracteriza-se por disfunção miocárdica grave, progressiva e, quase sempre, irreversível. Essa síndrome cursa com remodelamento cardíaco e, em especial, por aumento do volume e da esfericidade do ventrículo esquerdo com dilatação do anel mitral. Como consequência ocorre deslocamento lateral dos músculos papilares, estiramento das cordas tendíneas e consequente restrição da excursão sistólica dos folhetos mitrais. Esse conjunto de alterações biomecânicas causa insuficiência mitral funcional, um indicador de mau prognóstico. A plastia ou a troca da valva mitral foram introduzidas como alternativas cirúrgicas coadjuvantes ao tratamento clínico convencional e têm se mostrado eficazes em combater os sintomas de insuficiência cardíaca. Resta, todavia, demonstrar, seu benefício sobre o aumento da sobrevida em longo prazo.Dilated cardiomyopathy is characterized by severe, progressive myocardial dysfunction that is, irreversible. That syndrome leads to cardiac remodeling with augmentation of left ventricle volume and sphericity, dilation of the mitral annulus and dislocation of papillary muscles that pulls up the mitral cords thereby restraining leaflet excursion. These biomechanical modifications generate functional mitral valve regurgitation, a dismal prognostic sign. Mitral valve plasty or replacement was introduced as surgical coadjuvants to conventional medical treatment, with good symptomatic improvement. The long term survival benefit is yet to be demonstrated.

    Full Text Available Micotoxinas representam um vasto grupo de contaminantes químicos naturais originados a partir do metabolismo secundário de fungos filamentosos patogênicos. Elas são produzidas, principalmente, pelos gêneros Fusarium, Alternaria, Aspergillus e Penicillium, os quais podem contaminar grãos e cereais, como trigo, milho e soja. Conforme sua natureza e níveis de concentração, micotoxinas podem induzir efeitos tóxicos em animais de produção e humanos. Um estudo in vitro foi realizado para avaliar a susceptibilidade das células linfocitárias de frangos de corte a diferentes concentrações de ocratoxina A, deoxinivalenol e zearalenona. Cada micotoxina foi adicionada ao meio celular em diferentes concentrações (0,001; 0,01; 0,1 e 1μg/mL. A viabilidade celular e atividade de ecto-adenosina desaminase foram analisadas em 24, 48 e 72 horas através de ensaios colorimétricos. Para isso, foram utilizados 0,7x10(5 linfócitos/mL em meio RPMI 1640, suplementado com 10% de soro fetal bovino e 2,5 UI de penicilina/estreptomicina por mL, incubados em atmosfera de 5% de CO2 a 37 °C. Todos os experimentos foram realizados em triplicata e os resultados foram expressos como média e erro padrão da média. Os resultados obtidos demonstraram que tanto ocratoxina A como deoxinivalenol induziram proliferação linfocitária e baixa atividade enzimática in vitro (P0,05. Foi possível correlacionar os dados referentes à viabilidade celular e atividade de ecto-adenosina desaminase, sugerindo que, em concentrações mínimas, as micotoxinas testadas não estimularam a atividade da enzima, que possui ação pró-inflamatória e contribui para o processo de imunossupressão e, portanto, evitando um decréscimo na viabilidade celular. Este é o primeiro estudo feito com OCRA, DON e ZEA sobre linfócitos de frangos de corte em cultivos in vitro na avaliação desses parâmetros.

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

    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.

    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.

    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.

    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.

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%.

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%. The findings of the present manuscript confirm the importance of the cytological analyzes as a useful tool in selecting of lines meiotically stable and potentially fertile enabling a better planning of seed production of promising cultivars.

    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.

    Full Text Available Glioxal pode ser obtido a partir de biomassa (como da oxidação de lipídeos e não é tóxico ou volátil, tendo sido por isso utilizado no presente trabalho como substituto de formaldeído na preparação de resina fenólica do tipo novolaca, sendo usado como catalisador o ácido oxálico, que também pode ser obtido de fontes renováveis. A resina glioxal-fenol foi utilizada na preparação de compósitos reforçados com celulose microcristalina (CM, 30, 50 e 70% em massa, uma celulose com elevada área superficial. 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 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.

  11. 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

    Science.gov (United States)

    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 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.

    2007-01-01

    Full Text Available Diferentes tipos de fatores podem provocar a deterioração da habilidade individual em construir um self autônomo, afetando sua capacidade de interação social. Com o apoio de novas mídias algumas experiências procuram rearticular os selves deteriorados ou em processo de deterioração. Entre as características mais relevantes das novas mídias, a representação numérica parece ser a mais importante. As condições de possibilidade da cidadania são fortemente influenciadas pelo controle de recursos simbólicos, fundamentais no estabelecimento de relações interativas, consideradas aqui como uma pré-condição para o reconhecimento social. Nesse sentido, relevantes parecem ser não apenas os recursos materiais, dados pelas condições econômicas, mas especialmente os recursos simbólicos controlados pelos indivíduos. Este artigo aborda essas questões através de uma discussão teórica

    Full Text Available Com o objetivo de reduzir o consumo de água e o descarte do efluente tratado de uma indústria metal-mecânica foi proposta a avaliação técnica e econômica de cinco tecnologias de tratamento que pudessem proporcionar a reutilização do efluente. Foram levantados quatro locais para reúso e sugeridos critérios para cada um deles. Foi constatado que na adsor-ção com carvão ativado e na osmose reversa o efluente tratado por estes processos poderia ser reutilizado nos locais propostos e, com vazão de reúso de 2,5m³/h, os custos ficaram em US$ 1,14/m³ e US$ 1,70/m³ respectivamente. Para o ozônio e o dióxido de cloro, mesmo desinfetando o efluente, obteve-se apenas resultados satisfatórios, com custo de US$ 0,54/m³ e US$ 0,71/m³ respectivamente. Na coagulação/floculação todos os parâmetros analisados atenderam a dois locais de reúso, com exceção dos SDT e se obteve custo de US$ 1,57/m³With the objective to reduce the water consumption and the discharge of effluents in a metal industry, a technical and economical evaluation of five treatment technologies was proposed in order to reuse the effluents. Four sites for water reuse were chosen and for each of them criteria were suggested. It was evidenced that in the adsorption with activated carbon and reverse osmosis the effluent treated by these processes could be reused and, with the flowrate projected of 2.5m³/h, the cost attained US$ 1.14/m³ and US$ 1.70/m³ respectively. For the ozone and chlorine dioxide, even so the effluent was disinfected, gave only satisfactory results and the cost attained US$ 0.54/m³ and US$ 0.71/m³ respectively. For the treatment with coagulation/flocculation, all the analyzed parameters were successful in two reuse places, with exception of the TDS. The cost for this technology attained US$ 1.57/m³

    Full Text Available Sports in general, and traditional sports in particular, make a key contribution to the processes linked to the configuration of any identity. These activities can be studied as a reality «in its own right» (with a certain relative autonomy, as a part of a specific social subject, or as a diacritical social matter that enables us to characterize structures and social processes which, over time, could favour the changes, meanings and visions, whether considered legitimate or maligned, that are contained in these practices. This article deals with the traditional sport of lucha canaria [Canary-island wrestling], which has proved a revealing historical construct, to the extent that this popular game turned sports discipline underwent intense transformation during the 19th and early- 20th centuries. Its analysis provides an insight into the different social meanings, supports and principles associated with this activity, revealing a complex space of relations where the indigenous Guanche, historical tradition and an ongoing link with modernity are particularly relevant. All of this endorses the debate in recent decades in social anthropology and the social sciences regarding ethnicity, identity and sports.El deporte, y especialmente los deportes tradicionales, son una contribución de primer orden a los procesos de construcción identitaria.

    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.

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...

    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 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.

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

    International Nuclear Information System (INIS)

    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.

    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.

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

    International Nuclear Information System (INIS)

    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

    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 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.

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.

    Full Text Available Resumen: Asentados los conquistadores en la ciudad de los Reyes, una de sus primeras preocupaciones fue el acceso al agua, que consiguieron utilizando los canales de regadío del poblado precolombino sobre el que se había establecido la ciudad colonial. El 18 de enero de 1535, los regidores en pleno pidieron que el agua circulase por las calles y solares a través de las acequias. Entonces, el cabildo determinó que cada vecino se hiciese cargo de que la acequia pasara por su solar, es decir, que entrase a su propiedad y le diese salida para que se aprovecharan de ella los otros vecinos. El río Rímac ni las acequias proporcionaban agua en la cantidad ni en la calidad necesaria. De esta manera, se construyó un sistema de distribución de agua desde 1562 hasta 1578, que la llevara desde un manantial hasta la fuente dela Plaza Mayor. Los jesuitas y otras órdenes religiosas contribuyeron en la ampliación del sistema de agua potable, en la mejora de la tecnología y en el préstamo de dinero para acelerar los resultados.Palabras clave: Lima – Virreinato del Perú – Agua – Jesuitas. Abstract: When conquerors settled inLima, the City of the Kings as it was named, one of the first concerns was to have access to drinking water, which they captured from irrigation ditches opened up in pre-Columbian villages, where they established their colonial towns. The system was regulated by the city council in such a way that each resident had to take care of the section of the ditch crossing along his home in a collective endeavour of the neighbourhood. Since this water was insufficient either in quantity or in quality because the Rímac river did not provide it in adequate amount, the city was compelled to build between 1562 and1578 a water distribution system taken from a spring to conduct it to the Plaza Mayor. The Jesuits and other religious orders contributed to the expansion of the water system through loans of money and to the improvement of technology.Keywords: Lima – Peruvian viceroyalty – Water –  Jesuits.

    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 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.

  10. 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.

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.

    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.

    Full Text Available O objetivo deste estudo foi verificar se a prática do exercício físico (natação, iniciada em diferentes momentos da prenhez de ratas diabéticas, promove alterações no metabolismo materno. Após confirmação do diabete, induzido por Streptozotocin, ratas Wistar foram acasaladas e randomizadas em três grupos (n = 13 ratas/grupo: não-praticante (G1 ou praticante de exercício desde o dia zero (G2 ou sétimo dia (G3 de prenhez. O exercício consistiu de um programa de natação com intensidade moderada. Durante a prenhez, glicemia e peso corpóreo foram avaliados semanalmente. No final da prenhez, as ratas foram anestesiadas e dessangradas para obtenção de amostras de sangue para determinação de proteínas totais, triglicérides, colesterol total e VLDL-colesterol. Fígado e músculo foram coletados para dosagem de glicogênio hepático e muscular, respectivamente. Independente do momento em que foi iniciado, o exercício não alterou os níveis glicêmicos, a evolução do peso corpóreo e as concentrações de proteínas totais e glicogênio hepático e muscular. Porém, a natação iniciada no sétimo dia de prenhez diminuiu as taxas de triglicérides (G1 = 369,10 ± 31,91mg/dL; G2 = 343,32 ± 162,12mg/dL; G3 = 212,35 ± 70,32mg/dL, colesterol total (G1 = 176,48 ± 28,25mg/dL; G2 = 141,33 ± 19,77mg/dL; G3 = 129,86 ± 33,16mg/dL e VLDL (G1 = 64,92 ± 24,41mg/dL; G2 = 63,54 ± 28,31mg/dL; G3 = 42,53 ± 14,12mg/dL comparando com o grupo G1. Apesar de não se comprovar a influência do exercício físico sobre os níveis glicêmicos maternos, a prática diária de natação a partir do sétimo dia de prenhez mostrou-se benéfica para o perfil lipídico de ratas diabéticas. Esse resultado reforça a validade da associação da atividade física regular à dieta e insulina na gestação complicada pelo diabete.El objetivo de este estudio ha sido el de verificar si la práctica de ejercicio físico (natación, iniciada en diferentes momentos de preñez de ratas diabéticas, promueve alteraciones en el metabolismo materno.

Independiente del momento en que fue iniciado, el ejercicio no alteró los niveles glicéricos, la evolución del peso corpóreo y las concentraciones de proteínas totales y glicógeno hepático y muscular. Sin embargo, la natación iniciada en el séptimo día de preñez disminuyó las tasas de triglicéridos (G1 = 369,10 ± 31,91 mg/dL; G2 = 343,32 ± 162,12 mg/dL; G3 = 212,35 ± 70,32 mg/dL, colesterol total (G1 = 176,48 ± 28,25 mg/dL; G2 = 141,33 ± 19,77 mg/dL; G3 = 129,86 ± 33,16 mg/dL y VLDL (G1 = 64,92 ± 24,41 mg/dL; G2 = 63,54 ± 28,31 mg/dL; G3 = 42,53 ± 14,12 mg/dL comparado al grupo G1. A pesar de no comprobarse la influencia del ejercicio físico sobre los niveles glicéricos maternos, la práctica diaria de natación a partir del séptimo día de preñez se mostró benéfica para el perfil lipídico de ratonas diabéticas. Este resultado refuerza la validez de la asociación de la actividad física regular a la dieta e insulina en los embarazos complicados por diabetes.The aim of the present study was to evaluate if physical exercise (swimming program, begun in different periods of pregnancy of diabetic rats, promotes changes in the maternal metabolism. Severe diabetes was induced in female rats using Streptozotocin. The rats were mated and randomly assigned to three groups (n = 13 rats/group: sedentary (G1 or exercised from day zero (G2 or day seven (G3 to day 21 of pregnancy. The exercise consisted of a moderate swimming program. During pregnancy, the body weight and glycemic level were weekly evaluated. All the female rats were killed on day 21 of pregnancy to carry out laparotomy. The blood samples were collected to determine total protein, triglycerides, total cholesterol and VLDL-cholesterol. Liver and muscle samples were collected to determine hepatic and muscular glycogen, respectively. Regardless the initial moment, the exercise did not alter glycemic level, body weight evolution and total protein, hepatic and muscular glycogen concentrations. However, the swimming program begun on the 7th day of the pregnancy decreased the triglyceride rate (G1 = 369.10 ± 31.91 mg/dL; G2 = 343.32 ± 162.12 mg/dL; G3 = 212.35 ± 70.32 mg/dL, total (G1 = 176.48 ± 28.25 mg/dL; G2 = 141.33 ± 19.77 mg/dL; G3 = 129.86 ± 33.16 mg/dL, and VLDL (G1 = 64.92 ± 24.41 mg/dL; G2 = 63.54 ± 28.31 mg/dL; G3 = 42.53 ± 14.12 mg/dL cholesterol concentrations compared to G1 group. Physical exercise did not interfere on the maternal glycemic levels. Thus, the swimming program began on the day seven of the pregnancy was a beneficial treatment for the lipidic profile of the diabetic rats. This result validates an association of regular physical activity to diet and insulin treatment in pregnancy complicated by diabetes.

    Sporotrichosis is a fungal infection of subcutaneous or chronic evolution, inflammatory lesions characterized by their pyogranulomatous aspect, caused by the dimorphic fungus Sporothrix schenckii. Adenosine deaminase (ADA) is a "key" enzyme in the purine metabolism, promoting the deamination of adenosine, an important anti-inflammatory molecule. The increase in ADA activity has been demonstrated in several inflammatory conditions; however, there are no data in the literature associated with this fungal infection. The objective of this study was to evaluate the activity of serum ADA (S-ADA) and lymphocytes (L-ADA) of rats infected with S. schenckii. We used seventy-eight rats divided into two groups. In the first experiment, rats were infected subcutaneously and in the second experiment, infected intraperitoneally. Blood samples for hematologic evaluation and activities of S-ADA and L-ADA were performed at days 15, 30, and 40 post-infection (PI) to assess disease progression. In the second experiment, it was observed an acute decrease in activity of S-ADA and L-ADA (P schenckii alters the activities of S-ADA in experimentally infected rats, demonstrating the involvement of this enzyme in the pathogenesis of sporotrichosis.

    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.

The Distributable Reusable Ada Generated from an Object-Oriented Notation (DRAGOON) language is one such Ada extension. The DRAGOON syntax is described for classes, objects, and inheritance, and the syntax is evaluated against the following five criteria: readability, writeability, lack of ambiguity, ease of translation, and consistency with existing Ada syntax. The evaluation reveals several deficiencies in the notation. A revised syntax that corrects these deficiencies is proposed.

    Full Text Available Aim: Mycosis fungoides (MF is a cutaneous T cell lymphoma. The clinical and histophological diagnosis of early mycosis fungoides is usually diffucult. There is no special laboratory method for the diagnosis of MF disease and this is the most important problem in diagnosis and also follow up the effectiveness of treatment. Adenosine deaminase (ADA activity is a non-specific marker of T cell activation. In the present study, we aimed to investigate the levels of plasma and tissue ADA in patients with mycosis fungoides and to determine if ADA is an activation criteria for this disease. Materials and Medhods: The levels of ADA activities in both plasma and tissues were spectrophotometrically measured in 40 patients with MF and compared to those of 33 healthy subjects. Moreover, a subgroup analysis regarding ADA activities was performed in 17 patients who achieved complete remission after different kinds of treatments. Results: Patients with MF had more significantly elevated plasma and tissue ADA activity levels than those of control groups (respectively p0.05; MF patients in remission were found to have higher plasma levels of ADA activities than those of controls (p<0.001. Conclusion: These findings of the current study may provide an important clinical support for showing the roles of plasma and tissue ADA activity levels to predict disease activity in MF patients. In addition, levels of ADA activity measurements might be a marker to follow up in MF patients.

    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.

    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

    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.

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

    International Nuclear Information System (INIS)

    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

    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

    Paraplegia is known as an extremely serious and important complication of surgical repair in patients with a thoraco-abdominal aortic aneurysm. It is important to evaluate the artery of Adamkiewicz (AdA) before surgical repair to prevent paraplegia. But the AdA is difficult to visualize by the invasive and hazardous, conventional selective angiography. The aim of this study was to visualize AdA by MR angiography (MRA) and CT angiography (CTA). Twenty-one consecutive patients with a thoracic aortic aneurysm underwent both gadolinium-enhanced, three-dimensional MRA and CTA using multislice helical CT. The AdA was successfully visualized in 15 of the 21 patients (71.4%) by MRA, and in 17 of those 21 patients (80.9%) by CTA. Its continuity was depicted in 12 of 15 patients (80%) by MRA, and in 9 of 17 patients (47%) by CTA. AdA was visualized at 85.7% by MRA or CTA, respectively. This study shows that CTA is a much more sensitive method to detect AdA than MRA. On the other hand, MRA is better to evaluate the continuity of AdA from the descending aorta to the anterior spinal artery, than CTA. Therefore, MRA and CTA are both useful for a preoperative evaluation of AdA and its detailed vascular anatomy from the aorta to the anterior spinal artery. (author)

    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

    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

    Stent-graft implantation is an important means of clinical treatment for aortic dissecting aneurysm (ADA). However, researches on fluid dynamics effects of stent were rare. Computer simulation was used to investigate the interactions between bloodstream and vascular structure in a stented ADA, which endures the periodic pulse velocity and pressure. We obtained and analyzed the flow velocity distribution, the wall displacement and wall stress in the ADA. By comparing the different results between a non-stented and a stented ADA, we found that the insertion of a vascular graft can make the location of maximum stress and displacement move from the aneurysm lumen wall to the artery wall, accompanied with a greatly decrease in value. These results imply that the placement of a stent-graft of any kind to occlude ADA will result in a decreased chance of rupture.

    Full Text Available Objective: in midtrimester fetuses the principal site of hematopoiesis is the liver. In hematopoietic organs, stromal cells such as fibroblasts, epithelial cells, and macrophage-like cells develop networks to maintain hematopoiesis, i.e. hematopoietic stem cell self-renewal, proliferation, and growth, by interaction with hematopoietic progenitor cells. ECM glycoproteins produced by the stromal cells are known to play a critical role in the regulation of cell growth and differentiation. Numerous soluble and membrane-bound factors directly regulating haematopoiesis have been documented, but little is known about fetal hepatic stromal cell activity and stromal extracellular matrix protein-fibronectin, on fetal hepatic haematopoiesis. The binding of late stage erythroid cells to fibronectin has been well characterized and is believed to be critical for the terminal stages of erythroid differentiation. The intention of this article is to determine the role of fibronectin in fetal hepatic hematopoietic proliferation and differentiation in different stages of development. Material and method: we examined and compared the immunohistochemical expression of fibronectin in the hepatic stromal portal fields in the 1st, 2nd, and 3rd trimester of gestation respectively, in relation to the appearance of CD34 progenitor hematopoietic, stromal progenitor and vascular endothelial positive cells. Results: our results demonstrated a quantitative difference in the second trimester of gestation concerning the expression of fibronectin in the connective tissue stroma of the hepatic portal fields over the equivalent expression of the protein in the first (p Objetivo: en el segundo trimestre de la gestación, el principal foco de hematopoyesis del feto es el hígado.

Se sabe que las glucoproteínas de la MEC producidas por las células del estroma desempeñan un papel crítico en la regulación del crecimiento y la diferenciación celulares. Se han documentado numerosos factores solubles y de membrana que regulan directamente la hematopoyesis, pero se sabe poco de la actividad de las células del estroma hepático y de la proteína (fibronectina de la matriz extracelular en el feto en relación con la hematopoyesis hepática. La unión de las células eritroides tardías a la fibronectina está bien tipificada y se cree que es crítica para las etapas terminales de la diferenciación eritroide. La intención de este artículo es determinar el papel de la fibronectina en la proliferación y diferenciación hematopoyética del hígado fetal en las distintas etapas del desarrollo. Material y método: examinamos y comparamos la expresión inmunohistoquímica de fibronectina en los campos portales del estroma hepático durante los trimestres primero, segundo y tercero del embarazo en relación con la aparición de células progenitoras hematopoyéticas CD34, progenitoras del estroma y endoteliales vasculares, respectivamente.

Os mestiços apresentaram carne mais macia que a média dos puros, tanto pela avaliação por painel como pelo aparelho ";Warner-Bratzler Shear";, sendo a heterose retida de 9,39 e -11,36%, respectivamente. A heterose para suculência da carne, embora positiva em todas gerações de cruzamento, foi significativa apenas na G3. Comparando as carcaças de mestiços vs puros Charolês ou Nelore, verificou-se que os mestiços apresentaram maior quantidade absoluta de músculo, mas menor relação músculo/osso que os Charolês, maior quantidade absoluta de músculo, osso, gordura e maior relação músculo/osso e porção comestível/osso que os Nelore. A carcaça dos mestiços mostrou maior porcentagem de músculo e menor de osso que os Nelore e maior porcentagem de gordura e menor de músculo que os Charolês. A carne dos mestiços apresentou menor grau de marmoreio e maciez similar à dos Charolês, porém apresentou maior grau de marmoreio e maciez que a dos Nelore.The objective of this work was to evaluate the carcass physical composition and meat quality of steers, straightbreds (Charolais - C and Nellore - N, and 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 generation of rotational crossbreeding, feedlot finished with 52% corn silage plus 48% of concentrate in the diet. Crossbred steers were superior to the straightbreds mean for absolute weight of muscle, bone and fat of the carcass in all crossbreeding generations. 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.

    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.

    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

    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.

    To investigate the biological character of human adipose-derived adult stem cells (hADAS cells) when cultured in vitro and the relationship between hADAS cell's replication activity and the donor's age factor, and to assess the stem cells as a new source for tissue engineering. hADAS cells are isolated from human adipose tissue of different age groups (from adolescents to olds: 61 years old groups). The protein markers (CD29, CD34, CD44, CD45, CD49d, HLA-DR, CD106) of hADAS cells were detected by flow cytometry (FCM) to identify the stem cell, and the cell cycle was examined for P20 hADAS cells to evaluate the safety of the subculture in vitro. The generative activity of hADAS cells in different age groups was also examined by MTT method. The formula "TD = t x log2/logNt - logN0" was used to get the time doubling (TD) of the cells. The results showed that the cells kept heredity stabilization by chromosome analysis for at least 20 passages. The TD of these cells increased progressively by ageing, and the TD of the 61 years old group (statistical analysis of variance (ANOVA), P=0.002, PhADAS cells replication activity was found in the younger donators, and they represent novel and valuable seed cells for studies of tissue engineering.

    Background B cell chronic lymphocytic leukemia is one of the most frequent hematologic malignancies in the world. Cellular surface CD markers and serum Beta-2-microglobulin may be used as a prognostic tool in CLL patients. Objectives In the present study we introduce serum adenosine deaminase as a diagnostic marker in CLL. Materials and Methods Blood samples were collected from B-CLL and healthy subjects. White blood cell, red blood cell and platelet count and blood Erythrocyte sedimentation rate was recorded and serum Beta-2-microglobulin, Lactate dehydrogenase and total ADA enzyme activity were determined. Results Serum ADA activity was significantly higher in patients group than that of controls. ADA had a significant and direct correlation with B2M, WBC, LDH and ESR. However, there was not any relation between ADA and the stages of disease. Diagnostic cut-off, sensitivity and specificity of the serum ADA test were 27.97 U/L, 91% and 94%, respectively. Conclusions A higher ADA activity in patients group and its correlation with CLL markers were seen in our study. High diagnostic value of serum ADA in our study suggests that it might be considered as a useful screening tool among the other markers in CLL.

    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

    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.
