Opis:
The operation of thermal devices and installations, in particular heat exchangers, is associated with the formation of various deposits of sediments, forming the boiler scale. The amount of precipitate depends on the quality of the flowing liquids treatment, as well as the intensity of the use of devices. There are both mechanical and chemical treatment methods to remove these deposits. The chemical methods of boiler scale treatment include the cleaning method consisting in dissolving boiler scale inside heat devices. Worked out descaling concentrate contains phosphoric acid (V) and the components that inhibit corrosion, anti-foam substances, as well as anti-microbial substances as formalin, ammonium chloride, copper sulphate and zinc sulfate. Dissolution of the boiler scale results in the formation of wastewater which can be totally utilized as raw materials in phosphoric fertilizer production. As a result, both the preparation produced and its use are entirely free from waste.

Opis:
This paper examines the application of life cycle assessment (LCA) as an approach to foster the product and process oriented eco- innovation of enterprises, using the fruit and vegetable processing plant as an example. LCA, which is traditionally used to assess the impacts of a single product system on the environment, was applied in the enterprise context. This was made possible by forming an indicator describing the environmental profile of an enterprise, which is calculated by the sum of the multiplication of the environmental impact assessment (LCIA) results for individual unit processes within a particular impact category and their weights reflecting the structure of production in an enterprise. In order to distinguish and indicate the direction in which an enterprise should undertake its eco-innovative actions (implementing eco-innovations within the product or production process) the LCIA results are presented individually for products and production processes. The research was conducted in full compliance with the LCA methodology. LCA proved that the analysed enterprise has the largest negative impacts on the environment in the following impact categories: marine eco-toxicity, freshwater eco-toxicity, freshwater eutrophication, human toxicity and natural land transformation. They result primarily from the consumption of thermal and electric energy in the production processes. Therefore, to improve energy efficiency, the enterprise should take eco-innovative actions in the processes applied.

Opis:
We examine new mechanisms that introduce environmentally friendly eco- changes involving the elimination of noxious commodities and take into account the structure of demand without a detrimental effect to agents’ position. In the era of the fourth industrial revolution, these mechanisms allow eliminating unnecessary services or goods that are being replaced by modern technologies. We define optimal mechanisms under the criterion of distance minimization, when a small number of detrimental commodities is excluded from production processes as well as when producers are change-averse. The results have the form of theorems with rigorous proofs.

Opis:
In recent years, due to the growing importance of eco-design and tightening EU regulations entrepreneurs are required to implement activities related to environmental protection. It influences the development of methods and tools enabling the implementation of eco-design into practice, which are increasingly used by modern information technologies. They are based on intelligent solutions that allows them to better match the requirements of designers and allows for the automation of processes, and in some cases they are able to do the work themselves, replacing designers. Details are useful in areas that require calculations, comparisons and making choices, which is the process of eco-design. The paper describes methodology of pro-ecological product design oriented towards recycling, based on agent technology, enables the design of environmentally friendly products including recycling. The description of the methodology was preceded by a literature analysis on the characteristics of tools supporting eco-design and the process of its development was presented. The proposed methodology can be used at the design stage of devices to select the best product in terms of ecology. It is based on the original set of recycling indicators, used to evaluate the recycling of the product, ensure the ability to operate in a distributed design environment, and the use of data from various CAD systems, allows full automation of calculations and updates (without user participation).

Opis:
It is well known that sound absorption and sound transmission properties of open porous materials are highly dependent on their airflow resistance values. Low values of airflow resistance indicate little resistance for air streaming through the porous material and high values are a sign that most of the pores inside the material are closed. The laboratory procedures for measuring airflow resistance have been stan- dardized by several organizations, including ISO and ASTM for both alternate flow and continuous flow. However, practical implementation of these standardized methods could be both complex and expensive. In this work, two indirect alternative measurement procedures were compared against the alternate flow standardized technique. The techniques were tested using three families of eco-friendly sound absorbent materials: recycled polyurethane foams, coconut natural fibres, and recycled polyester fibres. It is found that the values of airflow resistance measured using both alternative methods are very similar. There is also a good correlation between the values obtained through alternative and standardized methods.

Opis:
The paper presents simulation research results of electric car motion processes with special functionality and construction facilitating its use by the disabled. The model of the structure: motor car – human being – environment has been used in the research. Special attention has been paid to the issue of the, so called, driveability of the car driven by a driver with a lower limb disability who is performing this activity from the wheelchair and not the driver seat. The driveability of the car has been assessed based on the technical stability analyses for the conditions of the ”moose test” manoeuvre. The research results have been used in the process of virtual pre-prototyping finalized with the construction of a non-commercial pre-prototype of a car created within the framework of ECO Mobility project. Simulation model of a motor car mechanical systems has been constructed in MBS technology. For description of the tyred wheel, TNO Delft Tyre model has been used. In the model of a control system, the description of programmable systems of the rear wheel drive electronic differential has been included. The model of a driver and the conditions for conducting the “moose test” manoeuvre have been presented.
Przedstawiono wyniki badań symulacyjnych procesów ruchu samochodów elektrycznych, ze szczególnym uwzględnieniem funkcjonalności i konstrukcji ułatwiającej jego wykorzystanie przez osoby niepełnosprawne. Model struktury: samochód - człowiek - środowisko został wykorzystane w badaniu. Szczególną uwagę zwrócono na kwestię tzw. właściwości jezdnych samochodu kierowanego przez kierowcę o niepełnosprawności kończyn dolnych wykonującego tę czynność z wózka, a nie siedzenia kierowcy. Właściwości jezdne samochodu zostały ocenione na podstawie analiz stabilności technicznej dla warunków manewru "testu łosia". Wyniki badań były zastosowane w procesie wirtualnego wstępnego prototypowania zakończonego budową niekomercyjnego przed-prototypu samochodu w ramach projektu ECO Mobility. Symulacyjny model układów mechanicznych samochodu został wykonany w technologii MBS. Do opisu koła z oponami został wykorzystany model opony TNO Delft. W modelu systemu kontroli został wykorzystany opis programowalnych systemów dla elektronicznego mechanizmu różnicowego napędu tylnych kół. Został przedstawiony model kierowcy i warunków przeprowadzenia manewru „testu łosia".

Within classic German manufacturing structures, costs of resources exceed all other cost factors by 46% [1]. Solitary focus on energy or labor costs as sources to raise companies profit no longer seems adequate. Nowadays material costs of the manufacturing industry are about 500 billion euro per year, connected with a saving potential of 100 billion euro per year. Also the belonging for sustainably produced products is raising and becoming a factor for guaranteed purchases [2]. A small and medium-sized enterprise fitted approach, which ensures to increase the transparency of internal process structures and allows a resource driven, ecological and economical assessment, is the main subject of this article.

Opis:
The problem of the optimal driving technique during the fuel economy competition is reconsidered. The vehicle is regarded as a particle moving on a trace with a variable slope angle. The fuel consumption is minimized as the vehicle covers the given distance in a given time. It is assumed that the run consists of two recurrent phases: acceleration with a full available engine power and coasting down with the engine turned off. The most fuel-efficient technique for shifting gears during acceleration is found. The decision variables are: the vehicle velocities at which the gears should be shifted, on the one hand, and the vehicle velocities when the engine should be turned on and off, on the other hand. For the data of students’ vehicle representing the Faculty of Power and Aeronautical Engineering it has been found that such driving strategy is more effective in comparison with a constant speed strategy with the engine partly throttled, as well as a strategy resulting from optimal control theory when the engine is still active.
Rozważono zagadnienie wyznaczenia optymalnej strategii sterowania pojazdem w czasie zawodów pojazdów rekordowych. Pojazd jest modelowany jak punkt materialny poruszający się po trasie o zmiennym kącie pochylenia. Minimalizowana jest ilość zużytego paliwa potrzebna do pokonania zadanego dystansu w zadanym czasie. Opracowano najbardziej efektywną technikę zmiany biegów w czasie przyspieszania. Założono, że pojazd jest napędzany w dwóch trybach: przyspieszania przy pełnej dostępnej mocy silnika i wybiegu, kiedy to silnik jest wyłączony. Zmiennymi decyzyjnymi są: numer biegu oraz prędkość pojazdu, przy której powinno nastąpić jego przełączenie z jednej strony, oraz prędkości pojazdu, przy których silnik powinien być włączony lub wyłączony, z drugiej. Wykorzystując dane pojazdu studentów reprezentujących Wydział Mechaniczny Energetyki i Lotnictwa Politechniki Warszawskiej wykazano, że taka strategia jest bardziej efektywna niż strategia jazdy ze stałą prędkością z częściowym dławieniem silnika oraz pewna strategia wynikająca z teorii sterowania optymalnego, gdzie silnik jest stale włączony.

Opis:
The decapod fauna from the Badenian (middle Miocene) deposits of western Ukraine comprises in total 31 taxa: 20 species, 9 taxa left in open nomenclature, and 2 determined at family level. Thirteen of these taxa are reported for the first time from the territory of Ukraine. Among them are the first records of Trapezia glaessneri Müller, 1976 in the Fore-Carpathian Basin and Pachycheles sp. in Paratethys. One taxon (Petrolisthes sp. A) probably represents a new species. The occurrence of this significant decapod fauna is restricted almost exclusively to the Upper Badenian (i.e., early Serravallian) coralgal reefs of the Ternopil Beds. The taxonomic composition of the decapods indicates that the Late Badenian depositional environment was a shallow marine basin dominated by reefs that developed in warm-to-tropical waters of oceanic salinity. The decapod assemblage from the Ternopil Beds is similar in its taxonomic composition to numerous decapod faunules from fossil reefs of Eocene to Miocene age from the Mediterranean realm and of Miocene age from Paratethys. In contrast, decapod remains are very scarce in Badenian siliciclastic deposits (Mikolaiv Beds) and are represented by the most resistant skeletal elements, i.e., dactyli and fixed fingers. This scarcity was caused by the high-energy environment, with frequent episodes of redeposition, which disintegrated and abraded the decapod remains.

Performance assessment of ejector-expansion vapor compression refrigeration system with eco-friendly R134a alternative refrigerants (R152a, R1234yf, R600a, R600, R290, R161, R32, and propylene) is presented for air-conditioning application. Ejector has been modeled by considering experimental data based correlations of component efficiencies to take care of all irreversibilities. Ejector area ratio has been optimized based on maximum coefficient of performance (COP) for typical air-conditioner operating temperatures. Selected refrigerants have been compared based on area ratio, pressure lift ratio, entrainment ratio, COP, COP improvement and volumetric cooling capacity. Effects of normal boiling point and critical point on the performances have been studied as well. Using ejector as an expansion device, maximum improvement in COP is noted in R1234yf (10.1%), which reduces the COP deviation with R134a (4.5% less in basic cycle and 2.5% less in ejector cycle). Hence, R1234yf seems to be best alternative for ejector expansion system due to its mild flammability and comparable volumetric capacity and cooling COP. refrigerant R161 is superior to R134a in terms of both COP and volumetric cooling capacity, although may be restricted for low capacity application due to its flammability.

Opis:
Echinoderms from the Badenian (Middle Miocene) of the Fore-Carpathian Basin of western Ukraine are facies restricted. The Mykolaiv Beds, stratigraphically older, yielded the starfish Astropecten forbesi (complete skeletons), two genera of sand dollars (Parascutella, Parmulechinus), and numerous other echinoids of the genera Psammechinus , Echinocyamus, Spatangus, Hemipatagus, Echinocardium, Clypeaster, Echinolampas, and Conolampas. The stratigraphically younger, calcareous Ternopil Beds yielded Eucidaris (complete coronae, isolated spines), Arbacina , Brissus, and Rhabdobrissus. Sixteen species of echinoids are distinguished and/or commented. A new brissid, Rhabdobrissus tarnopolensis sp. nov., is established. A mass occurrence of some species (Psammechinus dubius and Hemipatagus ocellatus) contrasts with that of mass aggregations (sand dollars and Echinocardium leopolitanum) by dynamic events in selected layers of proximal tempestites. Of special note is the occurrence of very small specimens, interpreted as juveniles (‘babies’) having been swept out of their restricted biotopes (‘nurseries’). Some species hitherto regarded as of Early Miocene age, and the problem of their persistence beyond the Fore-Carpathian Basin and/or migration into that basin during the Middle Miocene transgression are discussed.
