Physic learning usually requires more observation to form certain knowledge and concepts. Physic does not only consist of a collection of various knowledge or facts that can be memorized, but also consists of an active process of using the mind in studying natural phenomena that cannot be explained. Physics subject is one of the keys to success in increasing the ability to adapt to change and enter the world of technology. Therefore, certain ways are needed to convey the material in science lessons, especially physics. This study aims to produce Motion Graphic-based Work and Energy Learning Media on feasible work and energy materials in terms of materials, media, and students' responses. The research method used is research and development (R&D), using the 4D model (Define, Design, Develop, and Disseminate). The subjects were conducted in class X IPA 1, which consisted of 15 students. The instrument used is a questionnaire. The results showed that media could be used as a teaching media in the physics subject of work and energy based on expert judgment with very good categories for media, materials, and students' responses. So it can be concluded that Work and Energy motion graphic media can be employed as a ground-breaking teaching tool for engaging Work and Energy physic material.

This research aims to find out the pedagogical content knowledge (PCK) of prospective teacher related to material at the junior high school level in terms of their academic abilities. To achieve the research target, 2 instruments were used, namely 1) a core instrument to measure emotional intelligence in the form of a questionnaire, 2) an interview guide related to the core instrument that had been filled in. This research was conducted at the Faculty of Mathematics and Natural Sciences, UNM Makassar in the Mathematics Department. Subjects were categorized into 2 categories, namely categories I and II based on their academic abilities as seen from the GPA of students while studying in the Mathematics Education Study Program. Prospective teacher students are given the core instrument to fill in, then 2 subjects in each category are selected for analysis of the results of filling in the core instrument and conducting interviews. The results of this study are that student teacher candidates 1) still lack orientation towards science teaching, 2) their knowledge of the curriculum still needs to be improved, 3) knowledge about understanding students' abilities still needs to be improved, 4) about science learning strategies still needs to be improved again and 5) still need to improve more knowledge in evaluating the learning process to identify misconceptions.

Purpose: The aim of this paper is to capture the changes taking place in terms of capturing innovations, as well as the types of innovations emerging from them, characteristic of two research streams: classical and contemporary. Design/methodology/approach: The methodology applied in the article refers to the methodological canon of management sciences, including, among others, conceptual- theoretical research methodology. On their basis, a critical analysis of foreign and Polish literature on the subject in the field of management science, partly marketing and economics, was carried out. At the same time, a descriptive method and a comparative method were used to interpret and analyze the collected material. Findings: Significant changes taking place in the definition and classification of innovations by selected representatives of the studied currents were recognized. Significant factors causing these changes were identified, as well as the new values that appear in them. On this basis, it was shown that the understanding of innovation is significantly expanded over the years, because of which it should be considered incomplete. This justifies the continuing need to analyze emerging approaches and types of innovation. Research limitations/implications: The analysis of the subject matter in the proposed methodological approach makes it possible to systematize the knowledge of innovation in terms of defining the category "innovation" and its typology. Thus, it increases the recognition of the changes that accompany them. The important role of the factor of time, environment, information technology, values, and new needs of the recipients of innovations in the studied process is recognized. Originality/value: Deepening and updating the knowledge of defining categories of innovation and their classification. Evaluation of progressive changes in the scope of the concepts studied. Keywords: innovation, change, development, classifications of innovation. Category of the paper: A literature review.

Purpose This study aims to propose a visualized model of hot technology evolution to describe its development. Design/methodology/approach The basic concept is to divide a technological field into a timeline consisting of several patent clusters. Hot technology trajectories are then explored using their continuity, as well as the point in time at which they occur. Findings Patents in orthopaedics between 1999 and 2014 have been chosen as the research subjects and the field is divided into several hot technology trajectories. A further step is taken by interpreting high-frequency key terms. Three categories – spine-related materials, bone repairing materials and bone plates – have been identified. Practical implications The trajectories presented by evolving diagrams allow readers to understand the evolution of hot technology and help analysts to plan layout and strategies to remain competitive. Originality/value Patent clusters reflect the knowledge context of technology development. Previous studies have focused on only new technology evolution and have rarely explored the knowledge context of hot patents that have been frequently cited in recent years. Such patents often guide the development of technology.

Al fine di ottenere informazioni sulla suscettibilita' dei nanocompositi polimero-argilla alla fotodegradazione sono stati preparati, mediante polimerizzazione radicalica in situ, dei nanocompositi polistirene/montmorillonite (PS/MMTYx). Per facilitare la formazione di strutture esfoliate la montmorillonite e' stata modificata sostituendo i cationi inorganici con cationi dell'imidazolo. A tal proposito, oltre ai surfactanti dell'imidazolo (C12, C16, C18) gia' noti in letteratura, sono stati preparati dei nuovi cationi con una struttura di base vinilimidazolica nei quali sull'azoto in posizione 3 sono legate catene alchiliche a 20 e 22 atomi di carbonio. Altri nuovi cationi sono stati sintetizzati a partire da 1-metilimidazolo e da 1-decil-2-metil-imidazolo introducendo in posizione 3 catene alchiliche rispettivamente a 12, 16, 18, 20 e 22 atomi di carbonio.
Per alcuni nanocompositi PS/MMTCx e' stato valutato il grado di esfoliazione mediante diffrazione ai raggi X, microscopia a trasmissione elettronica (TEM) e microscopia a scansione elettronica (SEM). I risultati indicano che il grado di dispersione delle lamelle di argilla nella matrice polimerica aumenta in funzione della lunghezza della catena alchilica.
Il grado di esfoliazione e' stato anche valutato attraverso studi di degradazione termica condotti in ambiente sia inerte che ossidativo. Per questa via sono state determinate le temperature iniziali di decomposizione e le energie di attivazione apparenti di degradazione. I risultati indicano che i nanocompositi sono termicamente piu' stabili del polistirene e confermano un incremento del grado d'esfoliazione in funzione della lunghezza della catena alchilica del surfactante, associata con l'aumento della stabilita' termica. Sono state inoltre trovate relazioni con le proprieta' reologiche (frequenza di crossover) collegate al grado di esfoliazione dei campioni.
I campioni sono stati sottoposti ad un invecchiamento accelerato e l'evoluzione del processo fotoossidativo e' stato seguito mediante spettroscopia infrarossa (FT-IR). La velocita' di fotoossidazione dei campioni PS/o-MMT e del microcomposito e' stata piu' alta rispetto a quella del polimero vergine.
I risultati suggeriscono che la maggiore fotodegradazione dei nanocompositi e' da mettere in relazione al grado d'esfoliazione ed alla stabilita' dei surfactanti. Aumentando il grado di esfoliazione, aumentano le interazioni polimero/siti catalitici sulla superficie delle lamelle di argilla, ma contemporaneamente si registra un aumento di interazioni tra le catene polimeriche e le molecole del surfactante. Per questo motivo sono stati preparati e studiati copolimeri PS/Cx, miscele PS/Nx, PS/N10Nx e miscele di polistirene con ODTA e nanosilice. I risultati hanno confermato che i surfactanti, indipendentemente dalla lunghezza della catena alchilica, e la nanosilice, a causa dei gruppi silanolici presenti sulla sua superificie, determinano una diminuzione della stabilita' fotoossidativa della matrice polistirenica. Tra le miscele preparate, quelle contenenti derivati dell'1-metilimidazolo sono le piu' stabili. Questi campioni si fotoossidano piu' rapidamente del PS ma con una cinetica piu' lenta rispetto ai PS/Cx ed ai PS/N10Nx. Il confronto tra le cinetiche di fotodegradazione dei nanocompositi PS/MMTCx, PS/MMT/N10Nx e PS/MMT/Nx ha mostrato che i nanocompositi PS/MMT/Cx e PS/MMT/N10Nx sono molto suscettibili all'irraggiamento ultravioletto. I campioni PS/MMT/Nx hanno le cinetiche piu' lente tra tutti i nanocompositi studiati.In order to draw information on the polymer-clay nanocomposite enhanced susceptibility to photodegradation, polystyrene/montmorillonite nanocomposites were prepared via in situ bulk polymerization (PSMMTYx). To make easier to obtain exfoliated structures, montmorillonite has been treated with imidazolium salts to substitute the inorganic cations present among clay layers with imidazolium cations. The treatment has been carried out using, besides imidazolium surfactans (C12, C16, C18) already known in literature, some new cations based on the structure of 1-vinylimidazole in which, bonded to nitrogen in position 3, alkyl chain with 20 and 22 carbon atoms are present. Other new cations have been synthesized from 1-methylimidazole and from 1-decyl-2- methylimidazole bonding to nitrogen in position 3 alkyl chains carrying 12, 16, 18, 20 and 22 carbond atoms, respectively. The nanodispersion of the clay in the polystyrene matrix has been evaluated for some nanocomposites by X-ray diffraction (XRD), transmission electronic microscopy (TEM) and scanning electronic microscopy (SEM). The results show that the exfoliation degree of the clay platelets in the polymer matrix grows as a function of the alkyl chain length. The exfoliation degree has been also evaluated through thermal degradation studies carried out in inert and oxidative atmosphere. Through these studies initial decomposition temperatures and apparent activation energy of degradation have been determined. The results indicate that nanocomposites are more thermally stable than polystyrene and confirm an increase of exfoliation degree and thermal stability proportional to the surfactant alkyl chain length. Moreover correlations among exfoliation degree and rheological properties (crossover frequency) have been found. The samples have been subjected to accelerated UV aging and the evolution of the photooxidation process has been followed by Infrared Spectroscopy. The photooxidation rate of PS/o-MMT and microcomposite samples was higher than pristine polystyrene. The results suggest that the higher photodegradation rate of nanocomposite is correlated to the exfoliation degree and to the surfactant stability. Increasing the exfoliation degree, the interactions among the polymer and the catalytic sites on the clay platelet surface increase, but simultaneously the interactions among the polymer and the surfactant molecules increase too. For this reason PS/Cx copolymers, and PS/Nx, PS/N10Nx, PS/ODTA e PS/nanosilica blends have been prepared and studied. The results confirmed that surfactants, independently from the alkyl chain length, and nanosilica, through silanol groups on the surface, produce a decrease of the polystyrene matrix photooxidation stability. Among the prepared blends, the ones having cations deriving from 1-methylimidazole show the higher stability. These blends photodegrate faster than polystyrene, but with a rate slower than PS/Cx and PS/N10Nx. The comparison of photodegradation rates of PS/MMT/Cx, PS/MMT/N10Nx and PS/MMT/Nx nanocomposites showed that PS/MMT/Cx, PS/MMT/N10Nx were very susceptible to UV irradiation, while samples PS/MMT/Nx showed degradation rates slower than the ones of all the nanocomposites studied.

La tesi di Dottorato descrive l'applicazione web denominata miRo', sviluppata nell'ambito delle attivita' di dottorato svolte. miRo' e' una base di conoscenza per l'annotazione funzionale di microRNA e molecole di RNA non codificante coinvolte nella regolazione genica post-trascrizionale. Nella sua prima edizione, miRo' permetteva l'associazione di microRNA con processi e funzioni biologiche nonche' patologie che li coinvolgono attraverso le annotazioni funzionali dei geni da essi regolati. Questo tipo di tool si e' dimostrato utilissimo per la ricerca biologica di base e, soprattutto, biomedica di diversi gruppi internazionali operanti sia negli USA che in Europa ed in Israele.
La base di conoscenza permette inoltre di effettuare Data Mining avanzato e di poter valutare le associazioni miRNA - processo/funzione/patologia attraverso una funzione di specificita' che si e' rivelata significativa per le applicazioni. Nella seconda edizione di miRo', sono state introdotte una serie di informazioni su pathway, profili di espressione ed annotazioni genomiche inerenti i microRNA ed i loro target (siti fragili, CpG island, translocation breakpoints), indispensabili per cercare di capire la natura delle associazioni. Contestualmente e' stato progettato un sistema di annotazione con ontologie mediante text mining dei dati di letteratura biologica su Pubmed, con l'obiettivo di sviluppare una funzione di scoring per le associazioni miRNA - fenotipo.

Currently, teachers of reading and language arts are being asked to look closely at what materials are being used in their classrooms. As of today, 45 states have become proponents of the Common Core State Standards (CCSS). These standards have been created to “ensure that students are equipped with the necessary knowledge and skills to be globally competitive” (NGA, et al., 2008, p. 24). These standards mandate a higher percentage of what has come to be termed informational text. The first question that needs to be answered is what exactly is the definition of informational text and why is it important? The largest change noted in the shift to informational text is the percentage of text required. Informational text covers a very broad spectrum of reading material including biographies and autobiographies: “books about history, social studies, science, and the arts”; “technical texts, including directions, forms, and information displayed in graphs, charts, or maps”; and “digital sources on a range of topics” (Maloch & Bomer, 2013, p. 209). In the upper grades, the different subject areas are generally taught by a variety of teachers. These content area teachers are experts in their fields and much of their information is strictly informational in nature to begin with. The problem is that “Most teachers are not taught how to teach reading” (Gewertz, 2012, p. 1). This leads to the question of how teachers are utilizing informational texts in their classrooms. This chapter explores informational texts and the Common Core State Standards (CCSS).

With the increasing pressure of population, the energy demand is growing explosively. By 2050, it is expected that the world population may reach to about 9 billion which may result in the increase of energy requirement to about 12.5 trillion watts. Due to increasing pressures of population, industries and technology, concerns to find possibilities to cope with increasing demand of energy resources, arise. Although the renewable energy resources including fossil fuels, wind, water and solar energy have been used for a long time to fulfill the energy requirements, but they need efficient conversions and storage techniques and are responsible for causing environmental pollution due to greenhouse gases as well. It is thus noteworthy to develop methods for the generation and storage of renewable energy devices that can replace the conventional energy resources to meet the requirement of energy consumption. Due to high energy demands, the sustainable energy storage devices have remained the subject of interest for scientists in the history, however, the traditional methods are not efficient enough to fulfill the energy requirements. In the present era, among other variety of advanced treatments, nano-sciences have attracted the attention of the scientists. While talking about nano-science, one cannot move on without admiring the extraordinary features of carbon nanotubes (CNTs) and other carbon based materials. CNTs are on the cutting edge of nano science research and finding enormous applications in energy storage devices. Excellent adsorption capabilities, high surface area, better electrical conductivity, high mechanical strength, corrosion resistance, high aspect ratio and good chemical and physical properties of CNTs have grabbed tremendous attention worldwide. Their charge transfer properties make them favorable for energy conversion applications. The limitation to the laboratory research on CNTs for energy storage techniques due to low specific capacitance and limited electrochemical performance can be overcome by surface functionalization using surface functional groups that can enhance their electrical and dispersion properties. In this chapter, ways CNTs employed to boost the abilities of the existing material used to store and transfer of energy have been discussed critically. Moreover, how anisotropic properties of CNTs play important role in increasing the energy storage capabilities of functional materials. It will also be discussed how various kinds of materials can be combined along CNTs to get better results.

The indissoluble relationship, society-information sustained through the information exchange, is an essential facet in the existence of society, a reality that defines primarily the society in relation to all components of its development. With the increasing role of science in society’s development, area of scientific information was expanded, representing a wide range of communication fields. Scientific information has led to a multifaceted development of infodocumentary structures, activities and services. In the growing competition that takes place today in the university environment, a university can create its own significant advantages, relating to optimal access to the new information of its domain, based on a strong information technology infrastructure. Today, electronic materials for documentation are a bibliographic source of reference for the research process, elaboration of scientific work and teaching / learning processes. Involvement of digital libraries in e-learning process uses the Web to retrieve and access study materials. These libraries should not be treated as mere collections of digitized documents, but as an accumulation of collections, services and specialists supporting activities of creation, preservation, dissemination, and utilization of data, information and knowledge of that. The main goals of the digital library in supporting e-learning process using Web refers to improving students performance, increasing the quantity and quality of educational resources via the Internet, facilitating retrieval and access to these resources in order to optimally capitalize them and not least to ensure that these resources will be available over time. Web 2.0 Library enables users to retrieve needed information by the desired subject search, access to scientific resources and interact with experts in various fields of interest. Web 2.0 Library provides direct access to library catalogs, to scientific databases, collections of electronic books, reserved electronic courses, allowing communication through forums. It is recommended fruitful communication between the library and educational institution that it serves, the purposes of encouraging the learning process via the Internet, also involving students in this working relationship, expecting permanent feedback from them. The librarians sustain processes of selection, processing and indexing of information resources from the Web, allowing access to articles from databases, both in full-text version and the reviewed ones. The collaboration of the library with academic field that comprise it, with the researchers, the editors, will benefit in developing collections of online publications. Library involvement in electronic learning process needs library professionals that have good knowledge in IT, web, information and communication science, skills for optimal material selection, for classification of information resources into logical categories, to create indexes and search engines, for constant improvement of the classification categories. Development of web 2.0 technologies is a catalyst for libraries, in supporting e-learning processes developed in academic area. The concept created by web 2.0 determined the infodocumentary structures unit to pursue the goal: Library 2.0, as a pillar for the development of e-learning phenomenon.

Since the late 1970’s, computer-aided process planning (CAPP) has attracted a large amount of research interest, which has led to a huge volume of literature published on this subject. The literature encompasses both reviews and research articles. The review articles are mostly technologically oriented. This paper takes a different angle to look back the CAPP research, that is, a statistic approach. The paper analyses the journals that have been publishing CAPP research works. The concept of “Subject Strength” of a journal is introduced and used to gauge the level of focus of a journal on a particular research subject/domain, i.e. CAPP. Discussions about the recent CAPP research works are presented in different categories as they fall in. The term “Technology Impact Factor (TIF)” is introduced to assess the level of impact of a particular technology, in terms of citation counts. All discussions and analyses are carried out based on the data gathered from the Elsevier’s Scopus abstract and citation database. Finally, a discussion on the future development is presented. The literature suggests that this is the only review article of the similar nature in the first decade of the century.

One major problem in Natural Language Processing is the automatic analysis and representation of human language. Human language is ambiguous and deeper understanding of semantics and creating human-to-machine interaction have required an effort in creating the schemes for act of communication and building common-sense knowledge bases for the ‘meaning’ in texts. This paper introduces computational methods for semantic analysis and the quantifying the meaning of short scientific texts. Computational methods extracting semantic feature are used to analyse the relations between texts of messages and ‘representations of situations’ for a newly created large collection of scientific texts, Leicester Scientific Corpus. The representation of scientific-specific meaning is standardised by replacing the situation representations, rather than psychological properties, with the vectors of some attributes: a list of scientific subject categories that the text belongs to. First, this paper introduces ‘Meaning Space’ in which the informational representation of the meaning is extracted from the occurrence of the word in texts across the scientific categories, i.e., the meaning of a word is represented by a vector of Relative Information Gain about the subject categories. Then, the meaning space is statistically analysed for Leicester Scientific Dictionary-Core and we investigate ‘Principal Components of the Meaning’ to describe the adequate dimensions of the meaning. The research in this paper conducts the base for the geometric representation of the meaning of texts.

Institutional performance assessment is one of the major challenges for various stakeholders including national and institutional policymakers. Existing popular approaches to performance measurement rely on various factors besides research output, which have been criticized on various grounds. In this work, we present a sciento-text framework to assess the core competency/expertise of an institution at two levels: a broad thematic level, based on WoS subject categories, and a finer thematic level based on indexed keywords. The performance measures namely x_d- index and x-index are used for assessment at broad and fine thematic levels, respectively. While national policymakers can make use of x_d- index for the enhancement of national scholarly ecosystem, institutional policymakers and other stakeholders of the institution can make benefit from the wholistic usage of the framework to work for improving its broader expertise diversity as well as enhancing its fine level expertise within suitable disciplines.

The paper describes a research conducted on the Faculty of Education of the University of West Bohemia in Pilsen in 2011. The research aims to map the influence of project-based learning on the subjective perception of the academic achievement of students in the subject Information and communication technology (ICT). Target group was composed of high school students. Described research is a part of a broader research conception that focuses on a potential of project-based learning in educational area Information and communication technology. This conception of a project-based learning application in an educational area of ICT was determined problematic by an initial survey. Within the scope of this broader conception we already focused on adolescent student experience during project-based learning in ICT that included possibilities of emotional disorder reduction, published in (Mainz, Lovasov?, Magdin, 2012). This time, we focused on a potential of project-based learning in an area of perception of the academic achievement. Student?s performance in a subject is not determined only by his skills, but also by a manner in which he is aware of his skills. Self-perception is a major factor that influences learning, work motivation and determines a level of anxiety experienced by student in a task situations (Balcar, 1983). The research design consists of a preparatory part and a research and implementation part. In the preparatory phase, projects have been implemented in high school lessons of ICT. The projects were drawn according to the methodology of the Buck Institute for Education that allows very clear definition of boundaries among project-based learning, theme-based learning and problem-based learning. In the research and implementation part, the self-concept of student?s academic achievement was observed in these categories: evaluation of common intellectual skills, evaluation of specific skills for informatics and self-confidence in a performance in a context of a social group. For the purposes of the observation, a modified standardized psychometric tool - SPAS "Self-concept of the Academic Achievement of Children" (Matějček, V?gnerov?, 1992) was used. This tool was successfully used many times for evaluation of newly implemented educational methods. The results were processed according to the manual for the standardized psychometric tool and were compared to the results of control groups, in which project-based method was not implemented. The research was conducted in cooperation with the Department of Computer Science and Educational Technology and the Department of Psychology at the Faculty of Education of the University of West Bohemia in Pilsen.

The importance of nanotechnology standardization is to reach the main topic in developing standards, which is “uniformity in manufacturing and facilitating the commercialization of nano-products.” According to this goal, activities on standardization in nanotechnology have been started in Iran, where development of nanotechnology is assigned to National Nanotechnology Committee of Iran. This committee is working under direct supervision of presidency office. As written in the committee’s official website [http://www.nano.ir], one of the long term goals of this movement, according to the “fourth development program of Iran” is to reach appropriate share of world trade based on nanotechnology. For this purpose standard developing and quality management system is needed for facilitating industrial and technological cooperation and decreasing costs raised from quality unawareness. So our workgroup has selected nanotechnology standardization as one of its research topics. We have studied current state of different active countries in this field and find out that one can categorize these activities into two major groups, General and Specific. The general activities refer to those looking from the regulatory and nomenclature point of view. In the other side specific activities have done according to local contracts signed between manufacturers, organizations and business start-ups. As examples of the activities started in Iran we can mention: 1. Establishing National Laboratory Network for Nanotechnology by National Nanotechnology Committee of Iran. 2. Collaboration of the Institute of Standards and Industrial Research of Iran (ISIRI) with, International Standard Organization (ISO) for starting the new Nanotechnology TC (technical committee). Today, Iran is one of the 23 active members of ISO TC 229 on Nanotechnologies. 3. Academic research on standardization of measurement procedures used for nano-scale materials. We have gathered or proposed in our research some opportunities specifically for Iran, which may also be helpful for other developing countries to enhance their market position in the upcoming era of nanotechnology. These proposals can be listed as below: 1. Establishing a national committee for managing and regulating of nanotechnology standards; 2. Starting nanotechnology technical committee in Iranian Standard and Industrial Research Organization; 3. Actively collaborating with other countries and international standard institutes, insisting on the country’s core competencies; 4. Introducing Iran’s specific needs to international standard institutes; 5. Equipping national laboratories; 6. Collaborating with international laboratory networks; 7. Developing specific standards based on casual contracts; 8. Activation of researchers to focus on measurement procedures and methods; 9. Participation in regional seminars and workshops and initiation of such activities. With paying attention to these activities, we can find the opportunity of holding a highly referenced database and information center for nanotechnology related commerce. To organize the “nanotechnology technical committee” inside the ISIRI [http://www.isiri.org/], which is responsible for all standardization activities in Iran, we decided to follow the common inter organizational disciplines of this institute, but we suggested assigning 2 or 3 members of this committee, despite others, as full time members. These members would track international standardization activities, and would be the administrators of such activities within Iran. Actively collaboration with other countries and international standard institutes, insisting on the country’s core competencies, would have lots of benefits for country. Taking into consideration that, there is no comprehensive and global accepted nano-standard in the world, through these efforts we can introduce our main interested topics of standardization to international standard institutes (e.g. during our correspondences with Dr. Hatto from UK committee for standardization in Nanotechnologies, we received an offer to notice them our priorities in Nano-standards). To do so, ISIRI has announced his full support of new ISO TC on Nanostandards. To be able to play an appropriate role in this field, having laboratories with advanced equipments is something essential. Because of the reason that these facilities are costly, we decided to take the advantages of National Laboratory Network for Nanotechnology. The laboratories within this network can support nanostandardization process through measurement at nano scale, identifying characterization of nano structures and materials, and their physical and chemical properties (for more information about this network you can visit the following website http://nanolab.nano.ir). Having a well-known and advanced national laboratory network, Iran can provide services to other countries too, and also can become a member of international laboratory networks to develop it activities. The other activity that Iran is interested in is to take part in joint works with international standard making organizations to develop specific standards (e.g. characterization of nanoparticles in ceramics industry). After developing such standards they could be certified through authority standard making organization. Universities also can play an active role in nanotechnology standardization from different aspects. For instance they can do surveys to study priorities of country in this field, and also can study on measurement at nanoscale, characterization of nanomaterilas, test method subjects and etc. Also, some activities in this field have been done in some first rated universities in the country. Participating in regional seminars and making good connections between scientists who are working at this task is another way to have a good background about nano standardization and developing special standards in nano technology. Scientists can co-work in regional universities and laboratories and they can present their research results in such kind of seminars. The goal of such program is making a new task in science and a good relationship between researchers who are working at laboratories on nano standardization and governments. Developing specific standards based on casual contracts makes our universities, laboratories and industries strong for developing standards for special cases. Being strong in such contracts give our industries and universities a powerful goal for developing standards in special cases. Equipping national laboratories and Collaborating with international laboratory networks gives our industries and universities a wide range of abilities for making precision measurements and being in touch with other institutes. The researchers and engineers can use the results of each laboratory for their researches and measurements. In this way the special contracts can be stronger and appearance of Iran in seminars, workshops and commercial relations will be more effective. One of the most important decisions can be finding a proper industry in Iran which can compete in world trade. For this kind of industry using nano materials as the primary materials or in other steps of process and developing standards will be very helpful. This kind of researches will helpful for developing a long range policy for nanotechnology in Iran.

Abstract Binder jetting, also known as 3D printing, is an additive manufacturing (AM) technology utilizing a liquid-based binding agent to selectively join the material in a powder bed. It is capable of manufacturing complex-shaped parts with a variety of materials. This paper provides an overview of binder jetting of metals with a discussion about the knowledge gaps and research opportunities. The review deals with two parameter categories in terms of the material and process and their impacts. The achieved density, dimensional accuracy, and mechanical strength are summarized and analyzed. Further in-depth consideration of densification is discussed corresponding to various attributes of the packing, printing, and sintering behaviors. Though binder jetting has attracted increasing attention in the past several years, this fabrication process is not well studied. The understanding of powder spreading process and binder-powder interaction is crucial to the development of binder jetting but insufficient. In addition, the lack of investigation on the mechanical behavior of binder jetting metal part restricts the actualization of its wide-range applications.

Deep-drawing is one of the most important processes for the economic production of sheet metal parts, especially for high quantities. The forming forces during the process are a limiting factor for the producible shapes. A particular importance is associated with the tribology, because the percentage of friction forces on the total forces is relatively high. The friction between sheet metal and tool is influenced by several factors, such as surface characteristics of the work piece and the tool, lubrication conditions and process parameters, like the contact pressure and the sliding speed. Controlling these parameters will expand the process window for deep-drawing. Lately, servo presses provide the possibility of controlling the process speed in dependency of the process progress. The subject of this paper is the tribological investigation of deep-drawing processes. The friction coefficient decreases with an increasing sliding speed. Investigating this correlation and utilizing it for the application with modern servo technology for industrial use is the main objective of the presented research works. First of all the dependency of the friction coefficient on the sliding speed is investigated by the use of the strip drawing tests, which allows the control of every parameter independently. The dependencies are implemented in a FEM-simulation, evaluating the potential for real deep-drawing processes. Deep-drawing experiments are then used to validate the results of the simulation with a speed-dependent friction coefficient as well as for the verification of the force reduction due to the influencing of process speed. In the end, the numerical simulated results in comparisons to the experimental measured results are discussed.

In the educational sector, where scientific publications and articles are concerned, plagiarism detection systems are critical. Plagiarism occurs when someone copies a piece of content without the author's permission or citation. You'll need a lot of knowledge about plagiarism types and classes to detect such conduct. Thanks to recently developed tools and procedures, many types of plagiarism may now be recognized. Plagiarism detection has become a crucial concern as a result of advancements in information and communication technology tools (ICT Tools), as well as the availability of online scientific materials. Plagiarism detection has become a crucial issue with the availability of several software text editors. Plagiarism detection and the various types of plagiarism detection datasets used in identification systems has already been the subject of numerous research investigations. This paper discusses various types of plagiarism and various source code plagiarism detection tools developed. Despite the fact that there has been extensive study into systems for detecting source code plagiarism for many years, there is still a need to investigate a robust method.

The main recommendations of the panel report can be summarised under five key headings: Building the Scottish Bronze Age: Narratives should be developed to account for the regional and chronological trends and diversity within Scotland at this time. A chronology Bronze Age Scotland: ScARF Panel Report iv based upon Scottish as well as external evidence, combining absolute dating (and the statistical modelling thereof) with re-examined typologies based on a variety of sources – material cultural, funerary, settlement, and environmental evidence – is required to construct a robust and up to date framework for advancing research. Bronze Age people: How society was structured and demographic questions need to be imaginatively addressed including the degree of mobility (both short and long-distance communication), hierarchy, and the nature of the ‘family’ and the ‘individual’. A range of data and methodologies need to be employed in answering these questions, including harnessing experimental archaeology systematically to inform archaeologists of the practicalities of daily life, work and craft practices. Environmental evidence and climate impact: The opportunity to study the effects of climatic and environmental change on past society is an important feature of this period, as both palaeoenvironmental and archaeological data can be of suitable chronological and spatial resolution to be compared. Palaeoenvironmental work should be more effectively integrated within Bronze Age research, and inter-disciplinary approaches promoted at all stages of research and project design. This should be a two-way process, with environmental science contributing to interpretation of prehistoric societies, and in turn, the value of archaeological data to broader palaeoenvironmental debates emphasised. Through effective collaboration questions such as the nature of settlement and land-use and how people coped with environmental and climate change can be addressed. Artefacts in Context: The Scottish Chalcolithic and Bronze Age provide good evidence for resource exploitation and the use, manufacture and development of technology, with particularly rich evidence for manufacture. Research into these topics requires the application of innovative approaches in combination. This could include biographical approaches to artefacts or places, ethnographic perspectives, and scientific analysis of artefact composition. In order to achieve this there is a need for data collation, robust and sustainable databases and a review of the categories of data. Wider Worlds: Research into the Scottish Bronze Age has a considerable amount to offer other European pasts, with a rich archaeological data set that includes intact settlement deposits, burials and metalwork of every stage of development that has been the subject of a long history of study. Research should operate over different scales of analysis, tracing connections and developments from the local and regional, to the international context. In this way, Scottish Bronze Age studies can contribute to broader questions relating both to the Bronze Age and to human society in general.
