Texte intégralRésumé :
The World Wide Web (WWW) has much to offer clinicians, nurses, scientists and all those concerned with gerontology, including our patients and their relatives. This article reviews the history and structure of the WWW, outlines the basics of how to use it and what is available for the gerontologist. This is not a comprehensive list of all known webpages in gerontology, since this would not be possible, given the ever-changing nature of the WWW. Instead, this article offers a background knowledge and introduction to the types of resources that are available, enabling more productive use of the WWW for finding information in gerontology.

Morgan, S. « WWW Archive of Fourier Coefficients ». International Astronomical Union Colloquium 185 (2002) : 168–69. http://dx.doi.org/10.1017/s0252921100015918.
Texte intégralRésumé :
AbstractFourier coefficients are a valuable tool in the study of a wide variety of pulsating stars. They can be used to derive various physical parameters, including mass, luminosity, metallicity and effective temperature and are frequently used to discriminate between different pulsation modes. With the increase in large-scale surveys and the availability of data on the Internet, the number of Fourier coefficients available for study has expanded greatly and it is difficult to find all current data for individual stars or a subset of stars. To assist others in obtaining and making use of Fourier coefficients, an archive of published values of Fourier coefficients has been set up. Users can search for data on individual stars or for a range of parameters. Several Java programs are used to display the data in a variety of ways. The archive is located at the Web site http://www.earth.uni.edu/fourier/.

Texte intégralRésumé :
We are creating a World-Wide Web (WWW) introductory chemistry site that will incorporate many key features of an electronic chemistry curriculum, including flexibility, interactivity, extensibility, diversity, and self-assessment. The site will be accessible from browsers such as Mosaic and Netscape. Advantages of serving introductory chemistry from a WWW site include expanding access to chemistry instruction, platform independence, easing transitions between university units, and creating a curriculum responsive to diverse needs. Contributions and suggestions from the chemistry community can be incorporated easily and rapidly into the electronic curriculum. Since the WWW site could be used by any campus in the world having Internet access, we expect that our electronic curriculum will have a far-ranging impact on the way introductory chemistry is taught.

Johnson, Melody Blythe, et Mehrab Mehrvar. « Treatment of Actual Winery Wastewater by Fenton-like Process : Optimization to Improve Organic Removal, Reduce Inorganic Sludge Production and Enhance Co-Treatment at Municipal Wastewater Treatment Facilities ». Water 14, no 1 (24 décembre 2021) : 39. http://dx.doi.org/10.3390/w14010039.
Texte intégralRésumé :
Despite many wineries being equipped with onsite wastewater treatment, winery wastewater (WWW) co-treatment at municipal wastewater treatment plants (WWTPs) remains a common practice in wine-making regions. The complex and highly variable nature of WWW can result in negative impacts on WWTP operations, highlighting a need for improved co-treatment methods. In this paper, the feasibility of using the Fenton-like process to pre-treat WWW to enhance co-treatment at municipal WWTPs is assessed. First-stage pre-treatment of the WWW, in the form of dilution and settling or aerobic biological treatment, is used prior to the Fenton-like process. A three-factor BBD experimental design is used to identify optimal reaction time and initial H2O2 and Fe3+ concentrations. Chemical oxygen demand (COD) and total organic carbon (TOC) removal rates are not able to accurately reflect the extent of reaction. Additional trials identified solubilization of particulate COD and TOC, as well as samples handling requirements prior to analysis, as factors affecting the apparent COD and TOC removal rates. Inert suspended solids (ISS) generated during the sample handling process are found to be the response variable best suited to quantifying the extent of the Fenton-like reaction. Maximum ISS generation is observed at initial H2O2 and Fe3+ concentrations of 4000 mg/L and 325 mg/L, however, results suggest that optimal concentrations exceed these values. The impact of adding pre-treated WWW, with and without Fenton-like treatment, to municipal WWTPs’ primary clarifiers and aerobic bioreactors is also assessed via bench-scale trials. Challenges associated with co-treating WWW are found to remain despite the pre-treatment alternatives investigated, including negative impacts on simulated primary and secondary effluent quality. The Fenton-like AOP provides limited opportunity to optimize or enhance co-treatment at municipal WWTPs.

At the University of Strathclyde, second-year students reading for the BA in International Business and Modern Languages are being supported in developing personal transferable skills in communication via the World Wide Web (WWW). The ‘Webskills Initiative’ immerses them in major aspects of Website creation, including writing, design, preparation of graphics and Web page authoring. The aim of this paper is to present the Webskills Initiative as a case study and to examine the reactions of students to the course. There is also an analysis of student attitudes to using the WWW as a medium for communication.

Texte intégralRésumé :
Control of electron microscopes by a remote networked computer system has been implemented successfully in a variety of ways including via the World Wide Web (WWW). This approach works well with users who are familiar with the operation of the instrument and are experienced microscopists. However, many of our collaborations involve other scientists or engineers looking to us for analytical expertise. In order to accommodate collaborators with a broad range of skills and to allow them to interact remotely, in near-real time with a scientist operating an instrument, we have implemented a Virtual Collaborative Environment (VCE) based on a WWW server and the use of the server-push protocol.The system developed at NIST is a frames-based WWW page that is presented to the user with an index of instruments on the left side (FIG.l), live video pages to the right side, and a download area (via ftp) toward the bottom for data and high resolution images.

Texte intégralRésumé :
This paper presents N-Site, a distributed consensus building and negotiation support system, which is used to provide geographically dispersed teams with agile access to a Web-based group decision support system. Four teams located in France, Mexico, the Ukraine, and the United States participated in the N-Site project. Each team was required to research the problem using the World Wide Web (WWW). With this background, each team identified opportunities, threats and alternatives as a basis for developing a response to the Cuban Missile Crisis that confronted President Kennedy in October 1962. The strategic assessment model (SAM) (M. Tavana, J. Multi-Criteria Decision Anal.11 (2002) 75–96; M. Tavana and S. Banerjee, Decision Sci.26 (1995) 119–143.) was used by each team to choose a strategy that best fit the team's perspective. SAM and WWW enabled the teams to evaluate strategic alternatives and build consensus based on a series of intuitive and analytical methods including environmental scanning, the analytic hierarchy process (AHP) and subjective probabilities. The WWW was used to achieve interaction among the international teams as they attempted to negotiate a decision framework and select a diplomatic response. The project was assessed with a Web-distributed survey instrument. This use of the WWW has implications for international diplomacy as well as global business.

Texte intégralRésumé :
The slogan that "information is power" has undergone a slight change. Today, "information updating" is in the focus of interest. The largest source of information today is the World Wide Web. Fast search methods are needed to utilize this enormous source of information. In this paper our novel crawler using support vector classification and on-line reinforcement learning is described. We launched crawler searches from different sites, including sites that offer, at best, very limited information about the search subject. This case may correspond to typical searches of non-experts. Results indicate that the considerable performance improvement of our crawler over other known crawlers is due to its on-line adaptation property. We used our crawler to characterize basic topic-specific properties of WWW environments. It was found that topic-specific regions have a broad distribution of valuable documents. Expert sites are excellent starting points, whereas mailing lists can form trape for the crawler. These properties of the WWW and the emergence of intelligent "high-performance" crawlers that monitor and search for novel information together predict a significant increase of communication load on the WWW in the near future.

Texte intégralRésumé :
It is clear that the presence of an Islamic factor in WWW has become an objective reality, including in the post-Soviet Muslim countries. It could be determined as a Cyber-Islamic Environment (CIE). In the post-Soviet space the CIE is represented mostly by official Islamic structures, while the presence of unofficial religious organizations and individual preachers is more limited. Nevertheless the influence of the non-official CIE is significant and is capable to be converted into one of the mechanisms of social protests and revolutionary activities in post-Soviet Muslim countries in case of emergence of critical situations. It is clear that state authorities will accelerate control over the CIE in the coming years using various instruments against religious radicalism and extremism in WWW.

Texte intégralRésumé :
A large horticultural database and an electronic retrieval system for extension education programs were developed using compact disk-read only memory (CD-ROM) and World Wide Web (WWW) as the medium for information delivery. Object-oriented database techniques were used to organize the information. Conventional retrieval techniques including hypertext, full text searching, and expert systems were integrated into a complete package for accessing information stored in the database. A multimedia user interface was developed to provide a variety of capabilities including computer graphics and high resolution digitized images. Information for the CD-ROM was gathered from extension publications that were tagged using the standard generalized markup language (SGML)-based document markup language (International Standards Organization, 1986). Combining funds from the state legislator with grants from the USDA and other institutions, the CD-ROM system has been implemented in all 67 county extension offices in Florida and is available to the public as a for-sale CD-ROM. Public access is also available to most of the database through the WWW.

Texte intégralRésumé :
The information space of the Semantic Web has different characteristics from that of the World Wide Web (WWW). One main difference is that in the Semantic Web, the direction of Resource Description Framework (RDF) links does not have the same meaning as the direction of hyperlinks in the WWW, because the link direction is determined not by a voting process but by a specific schema in the Semantic Web. Considering this fundamental difference, the authors propose a method for ranking Semantic Web resources independent of link directions and show the convergence of the algorithm and experimental results. This method focuses on the classes rather than the properties. The property weights are assigned depending on the relative significance of the property to the resource importance of each class. It solves some problems reported in prior studies, including the Tightly Knit Community (TKC) effect, as well as having higher accuracy and validity compared to existing methods.

American Journal of Physiology-Renal Physiology 311, no 2 (1 août 2016) : F320—F329. http://dx.doi.org/10.1152/ajprenal.00153.2016.
Texte intégralRésumé :
Human organic anion transporter 1 (hOAT1), expressed at the basolateral membrane of kidney proximal tubule cells, mediates the active renal secretion of a diverse array of clinically important drugs, including anti-human immunodeficiency virus therapeutics, antitumor drugs, antibiotics, antihypertensives, and anti-inflammatories. We have previously demonstrated that posttranslational modification of hOAT1 by ubiquitination is an important mechanism for the regulation of this transporter. The present study aimed at identifying the ubiquitin ligase for hOAT1 and its mechanism of action. We showed that overexpression of neural precursor cell expressed, developmentally downregulated (Nedd)4-1, an E3 ubiquitin ligase, enhanced hOAT1 ubiquitination, decreased hOAT1 expression at the cell surface, and inhibited hOAT1 transport activity. In contrast, overexpression of the ubiquitin ligase-dead mutant Nedd4-1/C867S was without effects on hOAT1. Furthermore, knockdown of endogenously expressed Nedd4-1 by Nedd4-1-specific small interfering RNA reduced hOAT1 ubiquitination. Immunoprecipitation experiments in cultured cells and rat kidney slices and immunofluorescence experiments in rat kidney slices showed that there was a physical interaction between OAT1 and Nedd4-1. Nedd4-1 contains four protein-protein interacting WW domains. When these WW domains were inactivated by mutating two amino acid residues in each of the four WW domains (Mut-WW1: V210W/H212G, Mut-WW2: V367W/H369G, Mut-WW3: I440W/H442G, and Mut-WW4: I492W/H494G, respectively), only Mut-WW2 and Mut-WW3 significantly lost their ability to bind and to ubiquitinate hOAT1. As a result, Mut-WW2 and Mut-WW3 were unable to suppress hOAT1-mediated transport as effectively as wild-type Nedd4-1. In conclusion, this is the first demonstration that Nedd4-1 regulates hOAT1 ubiquitination, expression, and transport activity through its WW2 and WW3 domains.

Texte intégralRésumé :
The article attempts at studying language culture of a city on the material of the two leading websites, www.74.ru of Chelyabinsk and www.66.ru of Yekaterinburg. The choice of websites of the two main Ural cities is conditioned by their geographical position, similar role in the country as leading industrial centres. Language and cultural approach to website study has resulted in revealing general and special characteristics of the local city space and city image. Cognitive and discourse approach to city cyberspace research has shown the tendencies to choose both local and global issues for discussion widening the boarders of the local city culture by including actual issues for Russia and the whole world. Place names, local place names and city space verbal markers are frequently used in both websites creating true to life language and cultural message for the websites users, making city image recognizable and language culture of a city specific by using a few folk place names. City space markers have been outlined and grouped. The sites are characterized by similar content representation but differ in its realization. Diagrams and tables help verify the results of the city space analysis and website dynamics.

Journal of Nanomaterials 2017 (2017) : 1–11. http://dx.doi.org/10.1155/2017/4238697.
Texte intégralRésumé :
Anionic polymers with membrane permeation functionalities are highly desirable for secure cytoplasmic drug delivery. We have developed tritryptophan containing copolymer (P/WWW) of polymalic acid (PMLA) that permeates membranes by a mechanism different from previously described PMLA copolymers of trileucine (P/LLL) and leucine ethyl ester (P/LOEt) that use the “barrel stave” and “carpet” mechanism, respectively. The novel mechanism leads to solubilization of membranes by forming copolymer “belts” around planar membrane “packages.” The formation of such packages is supported by results obtained from studies including size-exclusion chromatography, confocal microscopy, and fluorescence energy transfer. According to this “belt” mechanism, it is hypothesized that P/WWW first attaches to the membrane surface. Subsequently the hydrophobic tryptophan side chains translocate into the periphery and insert into the lipid bilayer thereby cutting the membrane into packages. The reaction is driven by the high affinity between the tryptophan residues and lipid side chains resulting in a stable configuration. The formation of the membrane packages requires physical agitation suggesting that the success of the translocation depends on the fluidity of the membrane. It is emphasized that the “belt” mechanism could specifically function in the recognition of abnormal cells with high membrane fluidity and in response to hyperthermia.

A number of genomes of parasitic organisms are presently being sequenced in the public domain, including Plasmodium falciparum, Leishmania major and Trypanosoma brucei with the likelihood of at least expressed sequence tag (EST) projects for several filarial and apicomplexan species. The early and timely release of sequence data to the community via the World Wide Web (www), and the public databases, (EMBL and GENBANK), forms an invaluable resource. Data mining, or ‘haystack searching’ this resource is becoming more fruitful to all members of the scientific community as the volume of data, diversity of genomes sampled, and accessibility increase.

Texte intégralRésumé :
As more and more teacher preparation programs realize the need to include courses that deal with computer-assisted language learning, a crucial decision as to what is taught needs to be made, taking into consideration the various post-graduation goals ranging from teacher or teacher-trainer to researcher. Thus, the question of whether to go beyond teaching the potential uses of the computer and the Internet and to delve into how to create relevant computer-based tasks using the WWW and to train teachers in the use of advanced web page development techniques, including Flash, web-enabled databases, and the interactive possibilities of the WWW needs to be addressed. This paper tackles these issues and illustrates a sample approach in dealing with the grooming of the new generation of CALL researchers and practitioners. What can be accomplished during the first year of an MATESL program that highlights the importance of technology is explored through a reflective questionnaire, a computer capabilities matrix, and an analysis of web-based course projects. Nine first-year M.A. students participated in the study, which revealed that despite widely differing initial computer and Internet expertise among these future teachers and researchers, their knowledge of creating and using web-based materials increased significantly, culminating in a project in which the skills acquired throughout the semester were successfully integrated.

Texte intégralRésumé :
Logical frameworks and meta-languages are intended as a common substrate for representing and implementing a wide variety of logics and formal systems. Their definition and implementation have been the focus of considerable work over the last decade. At the heart of this work is a quest for generality: A logical framework provides a basis for capturing uniformities across deductive systems and support for implementing particular systems. Similarly a meta-language supports reasoning about and using languages.Logical frameworks have been based on a variety of different languages including higher-order logics, type theories with dependent types, linear logic, and modal logic. Techniques of representation of logics include higher-order abstract syntax, inductive definitions or some form of equational or rewriting logic in which substitution is explicitly encoded.Examples of systems that implement logical frameworks include Alf, Coq, NuPrl, HOL, Isabelle, Maude, lambda-Prolog and Twelf. An active area of research in such systems is the study of automated reasoning techniques. Current work includes the development of various automated procedures as well as the investigation of rewriting tools that use reflection or make use of links with systems that already have sophisticated rewriting systems. Program extraction and optimization are additional topics of ongoing work.

Texte intégralRésumé :
Topic Maps (TM) are standardized by ISO 13250 for the pur¬pose of semantic annotation of WWW resources. This paper presents the knowledge navigation system for E-Government information portal based on Topic Maps technology, including four layers: information resources layer, knowledge layer, information navigation server layer and application layer. The method of constructing topic maps from domain ontology is discussed. The knowledge layer is abstracted from large quantities of distributing heterogeneous municipal information resources by using TM. Navigation scope is built on the knowledge level which enlarges the navigation unit granularity and quantity of receiving information, shortens the navigation routing, improves the efficiency of navigation, and achieves the intelligent information retrieval. The research is valuable in E-Government and knowledge navigation.

Texte intégralRésumé :
With the integration of health information available on the World Wide Web (WWW) in clinical practice, information management becomes more important than ever before. Although an on-line system could provide nurses with timely and convenient access to health information for discharge teaching, most nurses still rely on traditional practices such as written discharge notes and brochures. Nurses find the volume of information on the WWW overwhelming, the task of sorting out irrelevant and inaccurate information too difficult, and the time to search for information too long. Professional use of these resources requires an alternative organization, such as data repositories (i.e. electronic databases.) These are organized collections of information resources with indexes that support precise and sensitive retrieval. The paper reflects on consideration that organizing and indexing of on-line health information resources for professional use has a pragmatic facet: meet actual and future needs and requests for information. Hence, an information resource should not only be analyzed in and of itself, but should also be analyzed from the point of view of what questions it may or may not answer in the future. To search effectively, both indexers and searchers must understand the language used to represent the documents. The concepts that nurses most likely will use to seek information are domain-specific and reflect their practice. Several nursing knowledge representation systems or terminology models sexist but the question arises as to whether their understanding and use makes them adequate representations for consistently effective searches. The paper also reports on the results of indexing Web Pages using a medical (including nursing) controlled vocabulary (MeSH).

E-learning is a model of learning carried out through the utilization of information and communication technology services such as internet, video/audio conferencing, or CD-ROM. It is a technology-based learning design of computer networks known as the world wide web (www). The design was developed through designing learning materials under a multimedia package and was integrated in a full online interactivity. Any form of learning components such as teaching or evaluation materials were distributed to learners through a computer network (online), so that learners who attended the program must be an IT literate person. In its implementation, e-learning could be applied to various fields of science including library science. Librarians who do such work require the ability and expertise to cataloging, indexing and classification. Web-based learning material helped students understand those materials easily.

GÜNEŞ, Yiğit. « Is it possible to change milk secretion of drugs with soy enriched diets in lactating ruminants ? » Journal of Istanbul Veterinary Sciences 6, no 3 (31 décembre 2022) : 145–51. http://dx.doi.org/10.30704/http-www-jivs-net.1142811.
Texte intégralRésumé :
Soy is the most commonly used protein supplement in beef and dairy diets. Soy, which is also used as a common protein source in animal feed, is palatable and has a good amino acid balance and high bioavailability. In vivo and in vitro interaction of flavonoids, including isoflavones such as genistein and daidzein, with several ABC transporters, including breast cancer resistance protein (BCRP/ABCG2), has been demonstrated. BCRP presence in ruminants could affect the efflux of hydrophobic toxins and drugs, including their active secretion to milk and a reduction in the withdrawal time of the drug milk residues. As a result of inhibition of efflux transporters such as BCRP, changes in drug pharmacokinetics and drug transfer into milk have been observed. In this respect, the use of forage supplemented with BCRP inhibitors may be beneficial to control drug accumulation in milk and prevent undesirable contamination of milk. It is aimed to reduce the drug withdrawal periods for dairy animals with the procedure in question. In this review, it is aimed to give information about the importance of soy-enriched diets in the nutrition of ruminants during the lactation period and the effect of transport proteins on the transfer of drugs into milk.

Texte intégralRésumé :
A new database containing all available experimental and evaluated β-delayed neutron data is presented in this paper. The database is the product of an international effort coordinated by the International Atomic Energy Agency. It comprises a microscopic section including all available experimental data on beta-decay half-lives, β-delayed neutron emission probabilities and spectra, as well as new systematics and global theoretical calculations for comparison. The beta-delayed neutron data for individual precursors have been benchmarked against available data on macroscopic properties such as total delayed-neutron yields and spectra, delayed-neutron decay curves and time-dependent group parameters using the summation method. All available measured macroscopic data have also been compiled in the macroscopic section of the database. The dedicated database is available online on the IAEA server (URL:http://www-nds.iaea.org/beta-delayed-neutron/database.html).

Texte intégralRésumé :
Algorithmic versions of stand density management diagrams (SDMDs) were developed for natural and managed black spruce (Picea mariana (Mill.) B.S.P.) stands. Specifically, the IBM-compatible PC-based algorithms (1) graphically illustrate site-specific size-density trajectories for eight user-specified initial density regimes, (2) given (1), calculate and subsequent tabulate periodic yield estimates (mean dominant height, density, mean volume, total volume, total merchantable volume, quadratic mean diameter, and basal area), and (3) given (2), graphically illustrate empirically-derived yield production curves for total merchantable volume ha−1 and stems m−3 with user-specified operability criteria superimposed. Instructions on acquiring the executable algorithmic versions including the required graphical subroutines via the Internet are described. Currently, the algorithms are restricted in applicability to central insular Newfoundland. Key words: stand density management diagrams, black spruce, algorithms, microcomputer, World-Wide Web (WWW), hypertext browser, file transfer protocol (FTP).

Texte intégralRésumé :
The Internet offers many new and unique opportunities to disseminate information. The development of the World Wide Web (WWW) and information browsers like Netscap, Mosaic, and simple-to-use server software like MacHTTP provides means to allow low-cost access to information, including pictures and graphics previously unavailable to most people. The Pennsylvania State Univ. variety trial garden annually tests >1000 plants. Information is gathered on garden and pack performance, and photos of superior plants and varieties are taken. To provide wider access to this information, we have begun development of a Cyberspace trial garden on the internet. This server contains a wide variety of garden trial information developed from trials conducted in State College and Dauphin, Pa.. This server and a similar effort at Univ. of Minnesota are being constructed cooperatively. Hot links are provided between the server in Pennsylvania and the one in Minnesota, providing users with seamless access to information from both servers.

Texte intégralRésumé :
This study employs a content analysis approach to analyze the Websites of four major science centers in Taiwan. The aim is to determine if their Websites meet the criteria of ‘Evaluating Science WWW Resources’ established by North Carolina State University. The criteria consist of five categories and 29 items. The five categories are: Science Content Issues, Navigation, Website Design, Performance, and Multimedia Issues. The results of this study indicate that the Websites of the four science centers mostly conformed to the criteria, and their e-resources are sufficient for the general public. However, several recommendations are proposed based from the results. In Science Content Issues, a description about the responsible authors including their credentials, emails, and biographical information should be added so that the content can be validated by scientists or professional educators. In Multimedia Issues, Web 2.0 social networks may be added to allow users to share information in real time.

Texte intégralRésumé :
AbstractThis article aims to give a broad outline of what the JISC Legal Information Service is and why it was set up. In particular it deals with the challenges of the Internet and the new legislation that attempts to regulate it or stimulate its use. The Internet is fast becoming embedded in the FE/HE sector, in teaching and learning, research and administration–ignore it at your peril some might say. Yet there are risks to this, in some cases, enthusiastic rush to embrace all things that utilise the WWW. The relative ease of access, extraction and dissemination on ‘the net’ has tempted some to overlook the legalities. This article summarises briefly the main areas of law under consideration and the potential costs of infringement. It explains that FE/HE is subject to this legislation sometimes in specific ways. It concludes by stressing the need for feedback from the sector including BIALL members in order that the service can improve.

Texte intégralRésumé :
A new simulator for Cellular Neural Networks (CNNs) is presented. In contrast to other simulators, the CNN cells are visualized in a grid structure, the values of input and states being represented by colors. Input and initial images can easily be generated and changed even while the integration of the system is in progress, and an oscilloscope function allows the quantitative study of CNN transients, thus providing insight into the dynamics of the network. For those who are new to the world of CNNs, a series of predefined templates set and demonstrations are available, which makes the simulator a valuable educational tool. Advanced users and CNN expert can examine manually-entered and parametrized templates and carry out experiments in a very broad spectrum of CNN theory and applications, including quantitative behavior, robustness aspects, settling time, state limitations, different output functions and numerical integration methods. The simulator is written in Java and publicly available on WWW and will run on any Web browser of the newer generations.

Texte intégralRésumé :
Resnu Mauliyana Mukti Wilutomo, Teguh Yuwono, 3 phase induction motor must work well and safely. Many types of interference have the potential to interfere with motor performance or even damage the motor itself, including due to power instability which includes imbalance between phase voltages and more phase currents. Monitoring an industrial activity especially monitoring the protection system is very important, it is intended that the disturbance that occurs in the 3 phase induction motor can be analyzed for the value and type of interference. Rapid technological development requires a monitoring system that is practical, fast and accurate. Sensors installed on this device are current sensors, voltage sensors, and speed sensors. The read, current, voltage and speed will be used as input signals to Arduino using the ADC (Analog to Digital Converter) process, Arduino programming uses C ++ language. ESP8266 wifi module) will upload the data from the ADC (Analog to Digital Converter) process to the database which is then displayed on the web using the available internet network. The web programming language used is PHP. This tool makes it easy to monitor a 3 phase induction motor because it can be done anytime and anywhere. There was a difference of ± 0.24A between the Tang Ampere measuring instrument and reading on the web. A ± 4V difference occurs between the Multimeter measuring instrument with readings on the Web. The maximum speed of the 3-phase induction motor with no load is 22Rpm between the tachometer gauge and the web display.

Texte intégralRésumé :
As the World Wide Web (WWW) expands, information is rapidly becoming more accessible. Using satellite data previously required high-end computers running complex imaging software, sophisticated downloading equipment, and high monetary support. Satellite data is now available on the internet for little or no cost and can be handled on standard desktop computers using common software programs. The purpose of our project was to determine the availability and cost of different types of data and how this data may benefit horticultural instruction. Satellite data currently is archived at NASA, NOAA, the Department of Defense, the US Geological Survey, and various meteorological departments throughout the world. Satellite data such as large-scale thermal imagery can be used to determine microclimate effects within urban areas, including the cooling effects of urban plants. Natural Density Vegetation Index (NDVI) imagery can indicate changes in vegetational cover or give general indications of plant health in large areas. NASA photographic imagery can show the effects of erosion on a large scale. Higher resolution imagery can give indications of plant stresses in large plantings such as orchards or vegetable plots.

Texte intégralRésumé :
E-Commerce has been going on since Netscape.com introduced the idea in 1995 when www was invented. Businesses / consumers that have been immersed in e-commerce transaction have reaped the benefits associated with such technological break-through, as consumers sit at comfort of their homes to transact business. However, the impediment that has hindered other businesses / consumers to transform to this technological business approach has been the trust associated with carrying out business; consumer trust across global cultures has been contentious. Authors, including Hofstede, Gefen et al. and Greenberg et al. have done research on culture differences across the globe and how these differences could affect behaviours towards accepting e-commerce for transacting business. There is therefore, the need for a global digital guideline / policy to protect all consumers and businesses that trade on the internet. Such a policy would hopefully allay the fears amongst nations’ cultures having difficulty in imbibing this wholesome technological advancement for enhanced business transaction. Conducting business transaction through brick-and-mortar approach is archaic and cumbersome and should be faded out completely.

Texte intégralRésumé :
DNA sequence chromatograms (traces) are the primary data source for all large-scale genomic and expressed sequence tags (ESTs) sequencing projects. Access to the sequencing trace assists many later analyses, for example contig assembly and polymorphism detection, but obtaining and using traces is problematic. Traces are not collected and published centrally, they are much larger than the base calls derived from them, and viewing them requires the interactivity of a local graphical client with local data. To provide efficient global access to DNA traces, we developed a client/server system based on flexible Java components integrated into other applications including an applet for use in a WWW browser and a stand-alone trace viewer. Client/server interaction is facilitated by CORBA middleware which provides a well-defined interface, a naming service, and location independence.[The software is packaged as a Jar file available from the following URL: http://www.ebi.ac.uk/∼jparsons. Links to working examples of the trace viewers can be found athttp://corba.ebi.ac.uk/EST. All the Washington University mouse EST traces are available for browsing at the same URL.]

Texte intégralRésumé :
Abstract As a contribution to the more general discussion on causes of language endangerment and death, we describe the language ecologies of four related languages (Bà Mambila [mzk]/[mcu], Sombә (Somyev or Kila) [kgt], Oumyari Wawa [www], Njanga (Kwanja) [knp]) of the Cameroon-Nigeria borderland to reach an understanding of the factors and circumstances that have brought two of these languages, Sombә and Njanga, to the brink of extinction; a third, Oumyari, is unstable/eroded, while Bà Mambila is stable. Other related languages of the area, also endangered and in one case extinct, fit into our discussion, though with less focus. We argue that an understanding of the language ecology of a region (or of a given language) leads to an understanding of the vitality of a language. Language ecology seen as a multilayered phenomenon can help explain why the four languages of our case studies have different degrees of vitality. This has implications for how language change is conceptualised: we see multilingualism and change (sometimes including extinction) as normative.

Texte intégralRésumé :
ABSTRACT Anabaena sp. strain PCC 7120, widely studied, has 145 annotated transposase genes that are part of transposable elements called insertion sequences (ISs). To determine the entirety of the ISs, we aligned transposase genes and their flanking regions; identified the ISs' possible terminal inverted repeats, usually flanked by direct repeats; and compared IS-interrupted sequences with homologous sequences. We thereby determined both ends of 87 ISs bearing 110 transposase genes in eight IS families (http://www-is.biotoul.fr/ ) and in a cluster of unclassified ISs, and of hitherto unknown miniature inverted-repeat transposable elements. Open reading frames were then identified to which ISs contributed and others—some encoding proteins of predictable function, including protein kinases, and restriction endonucleases—that were interrupted by ISs. Anabaena sp. ISs were often more closely related to exogenous than to other endogenous ISs, suggesting that numerous variant ISs were not degraded within PCC 7120 but transferred from without. This observation leads to the expectation that further sequencing projects will extend this and similar analyses. We also propose an adaptive role for poly(A) sequences in ISs.

Texte intégralRésumé :
AbstractA reference system is a relation connecting observables and their mathematical represententions. The principle of general relativity assures that any sort of coordinate system can be used to describe physical phenomena. Thus, any reference system is only a convention. There is no absolutely true reference system. Instead, people seek for abestreference system, whose meaning may differ thus need to clarify. Taking an example from Earth rotation, we discuss how to find such a best reference system. The definition of the best system will change as scientific understandings deepen and computational environments develop. Therefore, we can not stop improving reference systems. However, when replacing an existing widely-spread system, one must take great care to minimize the inconvenience caused by its transition, especially the inconvenience which users might endure. The Standards Of Fundamental Astronomy (SOFA) project being conducted by the IAU WG on Astronomical Standards has the opportunity to ease this troublesome task. The World Wide Web (WWW) will be a main device to realize the project, namely to provide working standards including reference systems to the world.

International Journal of Technology in Education 4, no 4 (1 octobre 2021) : 589–604. http://dx.doi.org/10.46328/ijte.126.
Texte intégralRésumé :
The current study uses a correlation design and multiple linear regression to determine whether generation, gender, and subject area predict teachers’ technology efficacy as measured by the Technology Proficiency Self-Assessment for 21st Century Leaning (TPSA C-21). An online survey was provided to all participants. The survey consisted of demographic questions and a technology self-efficacy instrument. Results demonstrate that gender and generation are statistically significant predictors of technology efficacy, namely on the Total, WWW, Integrated Applications, and Emerging Technologies Skills subscales of the TPSA C-21. The subject area variable, however, did not demonstrate a statistically significant ability to predict teacher technology efficacy scores on any subscale of the TPSA C-21. The findings of the current study add to the existing body of literature by enhancing understanding of the teachers’ perceptions of technology efficacy in one geographic location in the US. These findings are timely, especially given the largely technology dependent nature of education—whether in physical classrooms or in virtual settings and the increasing necessity of using technological tools in education settings. Implications are discussed, including suggestions for future research.

Texte intégralRésumé :
Context-aware advertising is one of the most critical components in the Internet ecosystem today because most WWW publisher revenue highly depends on the relevance of the displayed advertisement to the context of the user interaction. Existing research work focuses on analyzing either the content of the web page or the keywords of the user search. However, there are limitations of these works when being extended into mobile computing domain, where mobile devices can provide versatile contexts, such as locations, weather, device capability, and user activities. These contexts should be well categorized and utilized for online advertising to gain better user experience and reaction. This paper examines the aforementioned limitations of the existing works in context-aware advertising when being applied for mobile platforms. A mobile advertising system is proposed, using location tracking and context awareness to provide targeted and meaningful advertisement to the customers on mobile devices. The three main modules of this comprehensive mobile advertising system are discussed, including advisement selection, advertisement presentation, and user context databases. A software prototype that is developed to conduct the case studies and validate this approach is presented.

Texte intégralRésumé :
AbstractThis paper aims at presenting a new dataset including the melt events derived from microwave remote sensing occurring in Antarctica from summer 1979/80 to 2005/06. The method for detecting melt events and sources of error is presented, and then trends in melt duration for every pixel are extracted from the dataset, mapped and analyzed. The analysis focuses on two particular cases, and the main results show that: (1) the trends over the period 1980–2006 in the Antarctic Peninsula match with lengthening of the melt season on the ice shelves and, surprisingly, shortening of the melt season in the mountainous area of the peninsula; and (2) the trends over the period 1996–2006 on the entire continent show a dipolar pattern, with the western regions experiencing decreasing melt duration, whereas East Antarctica and the Ross Ice Shelf experience increasing melt duration. This pattern closely mirrors the temperature pattern expected when the Southern Annular Mode is in a decreasing trend, as it is over the period 1996–2006. For further analysis and validation, the dataset has been made available at http://www-lgge.obs.ujf-grenoble.fr/~picard/melting/.

Texte intégralRésumé :
As a result of the COVID-19 pandemic caused by the SARS-CoV-2 virus, which emerged from Wuhan, China in 2020, economic, social, and psychological problems occurred all over the world, mandating implementation of strict curfew, quarantine, travel restriction measures, and vaccinations against the virus. Though the source of the virus was not clearly revealed, initial case reports from a market in Huanan selling animal products, coupled with sequence analyses of the isolates, revealed close similarity to coronavirus isolated from bats (RatG13) and pangolins, questioning the suspect source of SARS-CoV-2 as zoonotic. Additionally, epidemiological and experimental studies indicated the presence of SARS-CoV-2, and its specific antibodies in many animals such as cats, dogs, ferrets, calves, and deer. Besides, determination detecting the virus in water samples including treated waters from wastewater treatment plants, fecal shedding, and possible fecal-oral transmission of the virus gained importance. Accordingly, vegetables and fruits irrigated with contaminated water, and foods such as shellfish grown in contaminated waters had the risk of carrying the virus. Although one of the most effective ways for protection against SARS-CoV-2 is mass and booster vaccinations, the emergence of new variants raises concerns on vaccines’ effectiveness against these variants. Thus, urgent implementation of one health concept addressing human, animal, and environmental health as a whole is mandatory to overcome this and other possible future pandemics. In this article, emergence, spread, zoonotic potential, fecal-oral transmission risk, and the possible role of food and water in the transmission of the SARS-CoV-2 virus were reviewed based on up-to-date published data.

Texte intégralRésumé :
Inflammation plays critical role in the onset and progression of osteoarthritis (OA), a joint disease affecting more than 10 % of the world's population. Exporing immunological mechanisms of osteoarthritis is essential. The present paper is a literature review of immunogenetic aspects of the pathogenesis of the disease. The study is aimed at analysis and summary of information concerning the immunogenetics and molecular mechanisms of osteoarthritis. Material and methods The original literature search was conducted on key resources including Scientific Electronic Library (www. elibrary.ru) and the National Library of Medicine (www.pubmed.org) with subsequent selection of articles, analysis and synthesis of information. Results and discussion Mutations in proinflammatory cytokine and receptor genes, metalloprotease genes, HLA genes and in the anti-inflammatory cytokine (IL-4) gene, polymorphisms in phospholipase and IL-2 genes are more common for OA patients than for healthy subjects. Epigenetic regulation in OA include a decreased methylation of the promoters of proinflammatory cytokine and metalloprotease genes and a decreased methylation of NF‑κB‑sensitive iNOS enhancer sites. OA patients show an increased activity of histone acetylases in the IL-6 promoter area. In contrast, the expression of anti-inflammatory cytokines is decreased due to the reduced activity of the SIRT1 deacetylase.

Texte intégralRésumé :
Metacognitive skills refers to individual abilities for regulating and controlling learning behavior. Orientation, goal setting, planning, monitoring, and evaluation are manifestations of those skills. Given that metacognitive skills directly affect learning behavior, they are a strong predictor of learning performance. Students display a huge variation in metacognitive skillfulness, dependent on age and experience. In this article, metacognitive skills are considered to be an acquired program of self-instructions, that is, an orderly series of condition-action rules that contain conditional knowledge about when to apply which skill, and operational instructions for how to implement a particular skill. This notion has implications for effective metacognitive instruction in deficient students. Prior to instruction, on-line assessments of metacognitive skillfulness during actual task performance are indispensable for the identification of deficient students and for tailoring metacognitive instruction to the individual needs of students. Instruction should subsequently address what skill to perform when, why, and how (WWW&H), embedded within the context of a given task. Moreover, instruction should explicitly inform students about the benefits of applying metacognitive skills to make them exert the required effort. Finally, teachers may act as role model to students by including explicit metacognitive instruction in their lessons.

Texte intégralRésumé :
When personal photo collections get large retrieval of specific photos or sets of photos becomes difficult mainly due to the fairly primitive means by which they are organised. Commercial photo handling systems help but often have only elementary searching features. In this paper, we describe an interactive web-based photo retrieval system that enables personal digital photo users to accomplish photo browsing by using multimodal interaction. This system not only enables users to use mouse click input modalities but also speech input modality to browse their personal digital photos in the World Wide Web (WWW) environment. The prototype system and it architecture utilise web technology which was built using web programming scripting (JavaScript, XHTML, ASP, XML based mark-up language) and image database in order to achieve its objective. All prototype programs and data files including the user’s photo repository, profiles, dialogues, grammars, prompt, and retrieval engine are stored and located in the web server. Our approach also consists of human-computer speech dialogue based on photo browsing of image content by four main categories (Who? What? When? and Where?). Our user study with 20 digital photo users showed that the participants reacted positively to their experience with the system interactions.

Texte intégralRésumé :
The Internet and World Wide Web (WWW) are evolving as an important communication technology. This paper aims to develop methodology for enabling better concurrent stamping part and die development, in the evolving Web technology. The characteristics of concurrent stamping part and die design are presented, and the necessity and feasibility of building Web-based concurrent stamping part and die development system is then discussed. Next, the overall architecture of Web-based concurrent stamping part and die design and development is established. The design services, which are the components of the Web server and play key roles in implementing the Web-based concurrent stamping part and die development, are then investigated in depth. Among the Web-based design services, the part shape analysis and feature-based cost evaluation are further illustrated in detail. While the system development approach including knowledge-based stamping part design and evaluation over Web is discussed, the cooperation and coordination between product designer and die designer are also presented with the illustration of a case study. The findings of this research allow the stamping part designer and the die designer to share product data, communicate with each other, and maintain operations consistency in the distributed cooperative sites on different product design and development platforms.

Proceedings of the Institution of Mechanical Engineers, Part C : Journal of Mechanical Engineering Science 220, no 11 (1 novembre 2006) : 1665–76. http://dx.doi.org/10.1243/09544062jmes220.
Texte intégralRésumé :
This paper is based on the information gathered within the Multi-Material Micro-Manufacture (4M) Network activities in the Processing of Metals Division (Task 7.2 ‘Tooling’) ( www.4m-net.org ). The aim of the task involves a systematic analysis of the partners' expertise in different microtechnologies for processing tooling inserts made of metal. The following technologies have been analysed: micromilling, micro-electrodischarge machining (EDM, including wire-EDM, sinking-EDM, and EDM-milling), laser micromachining, electroforming, and electrochemical milling (ECF) (an electrochemical machining innovative process proposed by HSG-IMAT). Considered tool-insert materials are nickel for electroforming, stainless steel for ECF, and tool steel (AISI H13) for all other processes. Typical features (ribs, channels, pins, and holes) required by micro-optics, microfluidics, and sensor and actuator applications have been selected to form the benchmark part and to carry out this analysis. The results provide a global comparison between the micromanufacturing processes mentioned earlier in terms of technical capabilities and cost effectiveness of different feature machinings. As a second result, the current limitations of these technologies concerning feature sizes, surface finish, aspect ratios, etc. have been identified. The main conclusion drawn is the absence of a consolidated technology to produce three-dimensional free-form shapes smaller than 100–200 μm to date.
