Moving and Fixed Biological Biofilm Systems in Wastewater Treatmentwhen dose an Application Makes Sense

This study demonstrates the optimization of different Biofilm applications in wastewater treatment for a cost-effective solution. The increase of wastewater treatment cost because of high treatment efficiency requested and energy consumption makes such applications very interested in this field. Therefore, aerated reactors for wastewater treatment units were designed to work as Submerged Fixed Biofilm Bed, on the basis of biofilm-microorganisms attached to monolithic plastic supports to increase the treatment efficiency. This application depends on the aerobic process and achieved by the aeration in BOD reduction and Nitrifications reactors (Oxidation of organic compounds and nitrification). This was implemented by mixing and transport treatment processes within the biofilm attached to the plastic fixed media. The anaerobic reactor in this study was designed also to be simultaneous the de-nitrification stage by the application of a moving bed de-nitrification reactor which was considered as a part of the wastewater treatment process to achieve high treatment efficiency for the study pilot plant. The one-year-scientific evaluation was conducted onsite for the municipal wastewater pilot plant includes a test series with well-defined treatment parameters (soft mixing of the suspending the moving bed carriers; intermediate solids removal unit prior to the nitrification reactors; the mechanism for preventing the carriers to move with the flow into the subsequent reactor) such as waste-water-flow, quality, temperature, salinity, organic and hydraulic load and extensive sampling). The above application of the compact-container-system is considered as a typical field of application, for the following reasons: Need of quality improvements discharged into water body, which is often in the vicinity of bathing beaches; Need for Nutrient-Removal-Systems to avoid algae growth going into water bodies and; Space limitations in a resort and saving the implementation capital cost). The comparison between the application of the biofilm concept and the activated sludge system saved more than 40% tank size; 85% space/area; and up to 30% construction cost.

Digital Shakespeare

Digital publishing, from early ventures in fixed media (diskette and CD-ROM) through to editions designed for the Web, tablets, and phones, radically transforms the creation, remediation, and dissemination of Shakespearean texts. Likewise, digital technologies reshape the performance of William Shakespeare’s plays through the introduction of new modes of capture and delivery, as well as the adaptation of social media, virtual reality, video gaming, and motion capture in stage and screen productions. With the aid of the computer, Shakespearean texts, places, and spaces can be “modeled” in new and sophisticated ways, including algorithmic approaches to questions of Shakespearean authorship and chronology, the virtual 3D reconstruction of now-lost playhouses, and historical geospatial mapping of Shakespeare’s London.

TRaNsMOG-RiFiER: Fictional Narratives as Catalyst for Experimental Instrument Building and Musical/Artistic Collaboration

The authors report on their artistic research project TRaNsMOGRiFiER and highlight musician-specific approaches to creating with technology that privilege the sharing of tools and practical knowledge. The use of fictional narratives as a catalyst for instrument building and art making is at the foreground of the discussion. By rethinking DIY/Maker culture with an emphasis on collaboration and collective creativity, the authors highlight the tension between the production of fixed media output and practices that resist encapsulation. TRaNsMOGRiFiER underscores the benefits of hands-on learning and presents a collaborative artistic platform with a focus on open-ended processes and ongoing change.

Wastewater Treatment by Using Biofilm Technologies as a Low-Cost Solution for Rural Areas

The increase of demands on treatment efficiency and cost effective solution for municipal and Industrial wastewater treatment technologies leads to new interest in the biofilm technology. Different fixed growth biofilm reactors are commercially used to increase wastewater treatment efficacy, saving space and energy. Aerated Submerged Fixed Biofilm Bed (SFBB) reactors work based on biofilms attached to plastic supports. Mixing and transport processes within the fixed media are achieved by the aeration in aerobic systems (oxidation of organic compounds and nitrification), and denitrification can be realized in anoxic conditions. The concept of application the moving bed in this study for denitrification reactor (MBDR) has been considered as a viable extension of the capabilities of a SFBB plant in the anaerobic-denitrification stage. Therefore, this novel study was implemented as pilot hybrid-reactor-container-plant to treat municipal wastewater of 200 PE, based on a combination of an aerated submerged fixed bed biofilm (SFBB) and an anoxic moving bed denitrification (MBDR) reactor. The one-year evaluation of this concept shows high nitrification, denitrification rates and, BOD reduction; by controlling the effluent (BOD5≤10 mg/l, COD ≤100 mg/l, TSS: ≤25 mg/l, NH4-: ≤2 mgN/l, NO3≤10 mgN/l)). However, Implementing of certain novel elements leads to improve operation process: (Mixing, intermediate solids removal unit, applicability of Moving bed for denitrification and submerged fixed film in aerobic reactor..etc).

LAJU PERTUMBUHAN KARANG Acropora formosa YANG DITRANPLANTASI PADA MEDIA TEMPEL DAN MEDIA GANTUNG

Corals are associations of millions polyps that live in symbiotic way with zooxanthellae algae. Most of the polyps live in colonies and form a reef. Coral reefs are rich ecosystems that contain diverse organisms living in it. However, the threat of damage increases with the pressure that enters the waters. Coral transplantation is one way of restorations that can be done to restore damaged corals by cutting live corals and then planting them in places where the corals have been damaged. This study aims to determine the growth rate of Acropora formosa corals that were transplanted on fixed and hanging media. Data was collected in Malalayang Coast Waters, Manado City, North Sulawesi. The research took place for seven months. Beginning with the coral transplant activity of Acropora formosa on fixed and hanging media, then continued with monitoring every month for six months. Transplanted corals were measured using a ruler to determine the length of the coral from the beginning to the end of the study and then the data was analyzed using Microsoft Excel. The results obtained for the average growth rate of Acropora formosa corals transplanted on fixed media were 0.8 cm and on hanging media 1.8 cm. Overall growth rate averaged 1.3 cm.Keywords: Coral, Coral Reef, Transplant, Acropora formosa.

alarm/will/sound: Sound design, modelling, perception and composition cross-currents

An ongoing international arts-research-industry collaborative project focusing on the design and implementation of innovative car alarm systems, alarm/will/sound has a firm theoretical basis in theories of sound perception and classification of Pierre Schaeffer and the acousmatic tradition. In turn, the timbre perception, modelling and design components of this project have had a significant influence on a range of fixed media, electroacoustic and media installation works realised in parallel to the experimental research. An examination of the multiple points of contact and cross-influence between auditory warning research and artistic practice forms the backbone of this article, with an eye towards continued development in both the research and the artistic domains of the project.

The Audience Reception of Algorithmic Music

Contemporary music research and practice have leveraged advances in computing power by integrating computing devices into many aspects of music—from generative music to live coding. This efflorescence of musical practice, process, and product raises complex issues in audience reception. This chapter employs a comparative analysis in a longitudinal study designed to understand the psychological aspects of the audience reception of algorithmic music. It studies four compositions from the latter part of the twentieth century late, presented on fixed media to avoid variability in musical performance. Using a modified think-aloud protocol to collect data, this study shows that reception theory may be applied to the audience reception of algorithmic music using a cognitive-affective model to further understand the process of decoding of meaning. This study puts forth a robust methodology for future longitudinal and comparative research in the audience reception of music and makes recommendations for further research.
