Cup plant (<em>Silphium perfoliatum</em> L.) is a tall, reaching up to 2.5 m, perennial plant that represents the Asteraceae family. <em>Silphium perfoliatum</em> L. can be applied in medicine, animal feeding, and as a decorative, honey-producing and energy production plant which proves its multi-functional features. Sowing material currently available in Poland is insufficient, which justifies the present attempts at propagating these plants in <em>in vitro</em> cultures. Therefore, <em>Silphium perfoliatum</em> L. seed sterilization and micropropagation processes were studied under controlled conditions <em>in in vitro</em> cultures. Among the tested methods, ACE proved to be the most effective for sterilization. The apical parts of seedlings were used as explants; they were placed onto MS media with growth regulators added. 4 growth regulator concentration variants were applied. The highest percentage of explants with lateral shoots (41.7%) and callus (90.3%) was obtained on MS medium with 5 mg x dm<sup>-3</sup> BAP + 1 mg × dm<sup>-3</sup> NAA added. Shoots were isolated and transferred onto MS rooting medium without growth regulators. The rooted plants were transferred to the greenhouse and acclimatised to <em>ex vitro</em> conditions.

Renewable energy sources can help the countries to achieve some of the Sustainable Development Goals (SDGs) provided from the recent 2030 Agenda, allowing for clean, secure, reliable and affordable energy. Biomass technology is a relevant renewable energy to contribute to reach a clean and affordable energy production system with important emissions reduction of greenhouse gases (GHG). An innovative technological application of biomass energy consisting of a burner coupled with an external fired gas turbine (EFGT) has been developed for the production of electricity. This paper shows the results of the plant modelling by Aspen Plus environment and preliminary experimental tests; the validation of the proposed model allows for the main parameters to be defined that regulate the energy production plant supplied by woodchips.

This work includes results of studies and experiments conducted on heat exchanger (heater) tubes of an energy production unit to determine the causes of their fractures. Experiments indicated that the main mechanism of such tube fractures is the simultaneous presence of relatively high vibrational bending stresses and corrosive agents. It was shown that the role of a vibrational bending stress due to high velocity of input steam is very impressive. The important point in this study was the branching of corrosion fatigue cracks during their growth in presence of NaOH and chloride ions. The use of impingement plates and water chemistry control were the most appropriate methods to prevent such failures.

The biomass industry is growing due to the current search for greener and more sustainable alternatives to fossil energy sources. However, this industry, due to its singularity, presents several challenges and disadvantages related to the transportation of raw materials, with the large volumes that are usually involved. This project aimed to address this internal logistics situation in torrefied biomass pellets production with two different biomass storage parks, located in Portugal. The main park receives raw material coming directly from the source and stores it in large amounts as a backup and strategic storage park. The second park, with smaller dimensions, precedes the production unit and must be stocked daily. Therefore, a fleet of transport units with self-unloading cranes is required to help to unload the biomass at the main park and transport the raw material from this park to the one preceding the production unit. Thus, the main goal was to determine the dimensions of the fleet used in internal transportation operations to minimize the idle time of the transport units using a methodology already in use in the mining and quarrying industry. This methodology was analyzed and adapted to the situation presented here. The implementation of this study allows the elimination of unnecessary costs in an industry where the profit margins are low.

In this study the methodology for probabilistic modeling of wind speed using computer oriented techniques is presented. This approach makes it possible to simulate the wind speed on a computer thereby allowing for proper planning and reliably designing matters involving wind. The computer program developed is used to simulate power production and to determine probability density function of wind power produced for reliability purposes and idle times of a wind power production plant for determining the back-up storage system needed. An example is given on wind energy production and standby storage requirements for Kuwait during the month of January.

Brazil Campos Basin is under large offshore oil production activity. Many new giant oil fields are under development. In many oil fields Brazil has been using ship tankers converted as FPSO platform vessel. At this moment four FPSO are in final construction phase to be installed in Campos Basin (P-43, P-48, P-50 and P-54). Many oil cargo tankers are transformed to work as FPSO. Although they are showing good characteristics, some problems are rising. The turret design approach was used in the primary FPSO’s design phase but recently the spread mooring system is also under installation in Campos Basin. Two converted FPSO’s (P-43 and P-48) were installed recently using spreading mooring system. The P-43 was installed at 800 m of water depth in Barracuda field at Campos basin. It is brother P-48 is installed at Caratinga field. Both platforms are designed to produce 300.000 barril/day. New ideas about Floating Production Storage and Offloading (FPSO) system have been in focus since some projects started working in an appropriately FPSO design direction. The Naval Architecture and Marine Engineering Department at COPPE/UFRJ has been investigating a new FPSO design and many ideas are under evaluation. One of these ideas is implement a ballast tank system to improve the floating platform behavior in waves with less structure stress. This paper presents the FPSO-H preliminary design. The aim of this project is investigate a new conception where deck are is used to separate accommodation and production plant. Also, the design applied the idea that the number of tanks should be increased to allow better weight distribution and improve the tanks inspection plain. In addition the design includes ballast tanks to increase the operator ability to control stability and vessel motion. The paper presents a case study of FPSO-H design for a Campos basin field. Graphics and tables shown the main results and recommendations are highlights for future work.

Abstract Due to the increasing integration of different disciplines, the complexity in the development of mechatronic production systems is growing. To address this issue, a multi-disciplinary design approach has been proposed, which follows the model-based systems engineering (MBSE) architecture and integrates the interdisciplinary modeling approach SysML4Mechatronics. In this article, the applicability of this approach in the machine and plant manufacturing domain is demonstrated using five use cases. These use cases are derived from industry and are demonstrated in a lab-sized production plant. The results of the application show that the approach can completely fulfil the proposed industrial requirements, namely interdisciplinary modeling, comprehensibility of system modeling, reusability of the modeling components, coupling different engineering models and checking data consistency.
