Technology-centred learning processes as digital artistic development: On the reciprocal effects of conceptual models, metaphors and presets

This case study looks at a self-directed learning process of a professional classical-trained musician adopting a previously unknown digital-material musical device. In order to achieve the desired artistic result, the musician has to modify his music-related action in favour of the device’s calls for action, which are shown to him by a preset session. For this purpose, a specific interface relation must be established in the connection between the user and the device. The case study is contrasted with data from its framing research project. Findings include aspects as affirmation or degrees of unfamiliarity and their respective impacts on the subject’s action repertoires. A model of learning in the context of digital media or interfaces is introduced and discussed. It offers a specific potential for identifying particularities of how meaning and functionality of digital-material musical devices are embedded into everyday artistic contexts.

Prediction of Biome-Specific Potential Evapotranspiration in Mongolia under a Scarcity of Weather Data

We propose practical guidelines to predict biome-specific potential evapotranspiration (ETp) from the knowledge of grass-reference evapotranspiration (ET0) and a crop coefficient (Kc) in Mongolia. A paucity of land-based weather data hampers use of the Penman–Monteith equation (FAO-56 PM) based on the Food and Agriculture Organization (FAO) guidelines to predict daily ET0. We found that the application of the Hargreaves equation provides ET0 estimates very similar to those from the FAO-56 PM approach. The Kc value is tabulated only for crops in the FAO-56 guidelines but is unavailable for steppe grasslands. Therefore, we proposed a new crop coefficient, Kc adj defined by (a) net solar radiation in the Gobi Desert (Kc adjD) or (b) leaf area index in the steppe region (Kc adjS) in Mongolia. The mean annual ETp obtained using our approach was compared to that obtained by FAO-56 guidelines for forages (not steppe) based on tabulated Kc values in 41 locations in Mongolia. We found the differences are acceptable (RMSE of 0.40 mm d−1) in northern Mongolia under high vegetation cover but rather high (RMSE of 1.69 and 2.65 mm d−1) in central and southern Mongolia. The FAO aridity index (AI) is empirically related to the ETp/ET0 ratio. Approximately 80% and 54% reduction of ET0 was reported in the Gobi Desert and in the steppe locations, respectively. Our proposed Kc adj can be further improved by considering local weather data and plant phenological characteristics.

Embryo Transfer

Assisted reproductive technologies (ART) have made tremendous advances, in last years. Artificial insemination is a method for achieving slow genetic progress in populations of animals. Many large and small ruminants are bred by AI, and more than a half million embryos are transferred every year around the world. Most of the ruminants sires used for artificial insemination were derived from embryo transfer. Improvements of reproductive biotechnologies of controlling the estrous cycle and ovulation have resulted in more effective programs for AI, superovulation of donor, and the management of ET. In the ruminants, ET procedure is a timely alternative that can allow good conception rates to be obtained constant in a year. There have been great advances of this biotechnique with on aimed to intensify the genetic progress between generations of farm. The gains is possible with the development of advanced reproductive biotechnique. The best current strategy in applying biotechnology to farmers is to use AI with sexed semen, so farmers will enjoy and benefit. The use of ET together with cryopreserved sexed embryos has a very specific potential for donor replacement and genetic improvement of the herd. In this chapter, procedures of the MOET protocol were described step by step.

Research / Design and Academia

Editorial Summary In her contribution »Research / Design and Academia« Susanne Hauser discusses institutional developments and changes in academia since the 1990s, alongside which disciplinary frontiers and thematic as well as methodological approaches have been re-examined and reorganized. She highlights systemic differences in funding as well as uneven particularity in methodological attempts as fundamental reasons for the different recognition of e.g. practice- based and traditional types of academic research in architecture. Against the background of her personal academic foundation in cultural studies, she traces the genesis of the architect’s education as a generalist, responsible for design and conception, creation and making. Considering the specific potential of design, she argues for the recognition of designing as a specific approach to the generation of knowledge. [Katharina Voigt]

Deprescribing Antidepressants in Older People – Breaking Up Can Be Hard to Do

Every drug review for older people should consider which medicines to continue, but equally important, which medicines can be discontinued. As we age, the balance between potential benefits and potential risks of medications often shifts towards more harm. For example, antidepressants are commonly prescribed in general, but in the older person, they carry specific potential harms. Further, there is data indicating that a substantial proportion of users have no evidence-based indications to continue antidepressants and could be candidates to try stopping treatment. We outline first the imperatives and evidence for deprescribing antidepressants and then finally the practical approaches to deprescribing.

Teknologi Pengolahan Kandungan Kromium dalam Limbah Penyamakan Kulit Menggunakan Proses Adsorpsi: Review

Permasalahan yang sering terjadi pada industri-industri saat ini adalah pengolahan limbah yang tidak sempurna. Salah satu jenis industri yang memerlukan perhatian serta pengolahannya adalah limbah yang mengandung kromium seperti pada industri penyamakan kulit. Limbah penyamakan kulit masih menyisihkan logam-logam berbahaya dalam limbahnya seperti logam berat kromium (Cr). Kromium yang digunakan untuk menghasilkan olahan kulit yang lebih halus. Sekitar 30-40% kromium akan terbawa dalam limbah cair penyamakan. Tingginya kadar kromium yang tersisa dan terbawa dalam limbah dapat menyebabkan toksisitas akut dan kronis terhadap lingkungan bahkan juga sangat berbahaya terhadap mahluk hidup. Salah satu penanganannya adalah dengan menggunakan metode adsorpsi yang dimana merupakan salah satu metode alternatif dengan berbagai keuntungan yang ada. Biaya penanganan yang relatif murah, proses yang sederhana, dan kemungkinan dapat didaur ulang merupakan beberapa keuntungan dari proses adsorbsi. Selain itu, proses adsorbsi dapat dimaksimalkan dengan menggunakan adsorben yang memiliki spesifikasi potensi tertentu terhadap penyerapan kromium. Artikel ini me-review perbandingan metode adsorbsi batch dan kontinyu pada proses pengolahan kandungan kromium dalam limbah penyamakan kulit.The waste management issue is one of the biggest problems in the industries recently. Every industry has a high probability of releasing toxic by-product to the environment in the form of waste. One example is in the leather tanning industry. Leather tanning waste still removes harmful metals in its waste, such as heavy metal chromium (Cr). Chromium is used to produce finer skin products. About 30-40% chromium will be carried in the tanning liquid waste. The high chromium levels remaining and carried away in the waste can cause acute and chronic toxicity to the environment and even very harmful to living things. Adsorption is one of the highly recommended methods available to overcome this problem. Relatively low handling costs, simple processes, and the possibility of being recycled are some of the adsorption process's advantages. In addition, the adsorption process can be maximized by using adsorbents that have specific potential specifications for chromium absorption. This article reviews batch and continuous adsorption methods in the processing of chromium content in tannery waste.

MATHEMATICAL MODEL OF VIBRATION PROCESSING OF METAL DURING WELDING OF BILLETS

This article discusses methods for numerical measurement of the effect of vibration frequency on the physical properties of the metal. A literature review of known studies on the effect of vibration on the physical properties of metal. According to the wave theory of vibration, by determining the natural frequency of oscillations of the plastic flow, it is possible to intensify the process of metal processing by pressure and to achieve a reduction in the magnitude of the deformation force. The mathematical model of pipe welded connection in the conditions of vibration influence taking into account the assumptions necessary for approximation of calculations is offered. Particular attention was paid to the specific potential energy of a single layer, which consists of the potential energies of interaction of individual particles. The dependences presented in the work allow to make positive conclusions about the application of mathematical modeling in order to predict the level of residual stresses in welds.

The Role of Information in Managing Interactions from a Multifractal Perspective

In the framework of the multifractal hydrodynamic model, the correlations informational entropy–cross-entropy manages attractive and repulsive interactions through a multifractal specific potential. The classical dynamics associated with them imply Hubble-type effects, Galilei-type effects, and dependences of interaction constants with multifractal degrees at various scale resolutions, while the insertion of the relativistic amendments in the same dynamics imply multifractal transformations of a generalized Lorentz-type, multifractal metrics invariant to these transformations, and an estimation of the dimension of the multifractal Universe. In such a context, some correspondences with standard cosmologies are analyzed. Since the same types of interactions can also be obtained as harmonics mapping between the usual space and the hyperbolic plane, two measures with uniform and non-uniform temporal flows become functional, temporal measures analogous with Milne’s temporal measures in a more general manner. This work furthers the analysis published recently by our group in “Towards Interactions through Information in a Multifractal Paradigm”.
