Planning Curricular Proposals on Sound and Music with Prospective Secondary-School Teachers
Sound is a preferred context to build foundations on wave phenomena, one of
the most important disciplinary referents in physics. It is also one of the
best-set frameworks to achieve transversality, overcoming scholastic level and
activating emotional aspects which are naturally connected with every day life,
as well as with music and perception. Looking at sound and music by a
transversal perspective - a border-line approach between science and art, is
the adopted statement for a teaching proposal using meta-cognition as a
strategy in scientific education. This work analyzes curricular proposals on
musical acoustics, planned by prospective secondary-school teachers in the
framework of a Formative Intervention Module answering the expectation of
making more effective teaching scientific subjects by improving creative
capabilities, as well as leading to build logical and scientific
categorizations able to consciously discipline artistic activity in music
students. With this aim, a particular emphasis is given to those concepts -
like sound parameters and structural elements of a musical piece, which are
best fitted to be addressed on a transversal perspective, involving
simultaneously physics, psychophysics and music.Comment: 12 pages with 5 figures. Submitted for publication in Physics

Modelling and simulation framework for reactive transport of organic contaminants in bed-sediments using a pure java object - oriented paradigm
Numerical modelling and simulation of organic contaminant reactive transport in the environment is being increasingly
relied upon for a wide range of tasks associated with risk-based decision-making, such as prediction of contaminant
profiles, optimisation of remediation methods, and monitoring of changes resulting from an implemented remediation
scheme. The lack of integration of multiple mechanistic models to a single modelling framework, however, has
prevented the field of reactive transport modelling in bed-sediments from developing a cohesive understanding of
contaminant fate and behaviour in the aquatic sediment environment. This paper will investigate the problems involved
in the model integration process, discuss modelling and software development approaches, and present preliminary
results from use of CORETRANS, a predictive modelling framework that simulates 1-dimensional organic contaminant
reaction and transport in bed-sediments
Research and Development Workstation Environment: the new class of Current Research Information Systems
Against the backdrop of the development of modern technologies in the field
of scientific research the new class of Current Research Information Systems
(CRIS) and related intelligent information technologies has arisen. It was
called - Research and Development Workstation Environment (RDWE) - the
comprehensive problem-oriented information systems for scientific research and
development lifecycle support. The given paper describes design and development
fundamentals of the RDWE class systems. The RDWE class system's generalized
information model is represented in the article as a three-tuple composite web
service that include: a set of atomic web services, each of them can be
designed and developed as a microservice or a desktop application, that allows
them to be used as an independent software separately; a set of functions, the
functional filling-up of the Research and Development Workstation Environment;
a subset of atomic web services that are required to implement function of
composite web service. In accordance with the fundamental information model of
the RDWE class the system for supporting research in the field of ontology
engineering - the automated building of applied ontology in an arbitrary domain
area, scientific and technical creativity - the automated preparation of
application documents for patenting inventions in Ukraine was developed. It was
called - Personal Research Information System. A distinctive feature of such
systems is the possibility of their problematic orientation to various types of
scientific activities by combining on a variety of functional services and
adding new ones within the cloud integrated environment. The main results of
our work are focused on enhancing the effectiveness of the scientist's research
and development lifecycle in the arbitrary domain area.Comment: In English, 13 pages, 1 figure, 1 table, added references in Russian.

Implementation of labcreator and the integration of cyberlab
With the development of the World Wide Web, online courses are becoming more and more popular in modern science education. CyberLab aims to solve an important issue in distance science education -- laboratory experiments in online courses. It is a toolkit that handles creation, exportation, and execution of virtual experiments (within web browsers). It consists of LabCreator and LabExecutor. With LabCreator, instructors can create virtual experiments and export them into intermediate files. Students can download those files from online course websites and execute them in LabExecutor on their own computers.
The paper reports on the completion of two important tasks in the development of CyberLab: (1) the implementation of LabCreator and (2) a system allowing exportation of the experiment to intermediate web accessible format and the loading of the experiment into LabExecutor.
The feasibility of the design and structure of CyberLab is proved by integrating the LabCreator and LabExecutor for the first time. The advantage of CyberLab is shown through a demonstration of the deployment of a virtual experiment
