This paper presents a knowledge based platform which has been developed to underpin sustainableleather manufacturing. The platform comprises three independent databases that share roughly thesame architecture. These databases are: Environmental Legislation Database for The Leather andFootwear Industry, Database for Clean Technologies in The Leather Industry and Analysis andTests for Leather, Research Centres and Laboratories. These databases contain informationregarding clean technologies such as ecological chemicals, leather processing machines and alsoabout restricted chemicals for leather, environmental legislation and research centres. The platformis intended to be an useful tool for companies, students, technicians, engineers and researcherswhose activity is related to the leather and footwear industry. It's aim is to promote technologicalprogress, economic efficiency and research through the valuable information gathered fromexperts and accredited sources. Moreover due to legal measure of reducing pollution in form oftreaties, conventions, directives, regulations, laws, players in the leather industry will find thisplatform useful in controlling the impact of the activities that they perform on the environment bytaking into account environmental legislation stored in the platform. Aspects of the platform suchas: the architecture, access, records, search, administration are investigated. Issued relating toenvironmental pollution generated by leather and footwear industry, Romanian and Europeanlegislation on environmental regulation, clean technologies in the leather industry are considered.

The purpose of the paper is to present the synthesis and characterization of hydrogels prepared by free-radical copolymerization of acrylamide and acrylic acid in aqueous solutions using potassium persulfate as initiator and trimethylolpropane trimethacrylate as cross-linker, via the radiation technique. The samples were subjected to electron beam treatment in the dose range of 2 to 4 kGy and the influence of the absorbed dose and amount of cross-linker on the swelling properties, diffusion coefficient, and network parameters of hydrogels was investigated. A possible reaction mechanism for acrylamide/acrylic acid/trimethylolpropane trimethacrylate hydrogels was also suggested. The structure and morphology of hydrogels were characterized by Fourier Transform Infrared Spectroscopy and Scanning Electron Microscopy. © 2016 Gabriela Craciun et al.

Leather industry has to cope nowadays with major environmental problems because of thepolluting processes (a World Bank report has placed the leather industry in the ninth place whenconsidering the environmental impact).Therefore, increasing the environmental efficiency in theleather sector is the major aim of leather, auxiliary materials and equipment manufacturers. Thedevelopment of new tanning agents and new technologies is required to cope with the increasinglyhigher environmental pressure on the current tanning materials and processes such as tanning withchromium salts. The original contribution of this work in solving the above problems has involvedthe use of solid titanium wastes (cuttings) resulting from the process of obtaining highly puretitanium (ingots) in the preparation of new tanning compounds intended to increase theenvironmental efficiency of the leather sector.

Even the optimization of common chromium tannage, and combined tannage with chromium andother tanning materials have led to outstanding results related to the lowered pollution level ineffluents and sludge, the problem has not been solved wholly. The single solution for this problemis finding out an environmentally friendly alternative to chromium tannage. This work also iswithin the above line, aiming to obtain wet-white leather by an organic tanning process in order toreduce chromium in tannery effluent.

The purpose of this paper is to examine relevant aspects of quality of ecological leather used infootwear manufacture in Romania, from the clients' perspective. The main method used in thestudy is the survey employing questionnaire application to a non-probabilistic sample of Romanianfootwear clients. The paper examines conceptual models proposed in relevant quality literatureand advances a conceptual and applied framework for quality and ecological aspects for leathermadefootwear, from a customer's perspective. This framework can provide a valuable basis forthe development of new ecological products in the leather and footwear sector, and also guide theirintroduction to the market based on assessed consumer preferences in Romania. In the future, alarger empirical study can be employed to investigate the validity of the framework.

Ground reaction force occupies an important place in the overall context of human motion analysis. The body's reaction to changes in footwear-whether they are shoe modifications and inserts or orthopedic corrections-depends on the time period within which a particular type of footwear is used. In fact, the biomechanical effects of changes in footwear must be differentiated according to the time needed for the body to adapt to these changes. The purpose of this study was to determine the ground reaction force depending on the characteristics of the materials used for the sole in normal gait on different types of ground surfaces.

Experts share their views on the emergence of the smart tannery enterprise. They present a multi-agent architecture for leather processing control, along with a case study that simulates the behavior of the multi-agent TANMAS@ architecture in dealing with the control of leather processing to justify their views on the smart tannery enterprise. They state that the existing current automation systems must operate in complex, unpredictable environments which consists of a wide range of manufacturing resources distributed across a large geographic area.

The foray into structures of artistic image in environmental decorative arts aims, on the one hand, at the comparative analysis of artistic discourse in three different registers of expression: the decorative and the plastic register, and on the other hand, it aims to identify the icono-plastic sign as carrier of the archetypal message, in two distinctive types of logos: poetic and narrative. The third register of expression is the material one, defined by artistic technologies. Aesthetic interpretation stays in the area of deciphering the artistic message, mostly symbolic, while semiotic analysis aims to decipher the inner mechanisms of the image, and the artistic imagination, defining icono-plastic signs. Undertaking the materialization of the work, throughout the whole trajectory of achieving the decorative cultural product, is called artistic technology. It is a creative technology at the conceptual level, but framed within technical steps to achieving the environmental decorative product, which are very clearly defined as technological operations. Coming out of the major area of aesthetics and subjected to semiotic analysis, the artistic image transgresses, in theory, from a harmonic matrix of analysis, specific to aesthetics, into an expressive matrix, specific to discourse analysis, visual rhetoric. The whole approach, as well as the result of semiotic analysis of a decorative art project idea, will lead, step by step, to outlining an artistic technology, which becomes itself part of the cultural product symbolics, a technological style thus emerging. Artistic technology analyzed in terms of semiotics, which is the subject of the case study for the "Red apple" project is leather embroidery, industrially manufactured. The purpose of the whole scientific endeavor is to shape the guidelines of a framework artistic technology to further develop a number of artistic products with cultural identity, for modern domestic environmental spaces: private homes with determined environmental design or public spaces: institutions, libraries, airports etc.

Current clinical strategies for adipose tissue engineering (ATE), including autologous fat implants or the use of synthetic surrogates, not only are failing in the long term, but also can't face the latest requirements regarding the aesthetic restoration of the resulted imperfections. In this context, modern strategies in current ATE applications are based on the implantation of 3D cell-scaffold bioconstructs, designed for prospective achievement of in situ functional de novo tissue. Thus, in this paper, we reported for the first time the evaluation of a spongious 60% collagen and 40% sericin scaffold preseeded with human adipose-derived stem cells (hADSCs) in terms of biocompatibility and adipogenic potential in vitro. We showed that the addition of the sticky protein sericin in the composition of a classical collagen sponge enhanced the adhesion and also the proliferation rate of the seeded cells, thus improving the biocompatibility of the novel scaffold. In addition, sericin stimulated PPARγ2 overexpression, triggering a subsequent upregulated expression profile of FAS, aP2 and perilipin adipogenic markers. These features, together with the already known sericin stimulatory potential on cellular collagen production, promote collagen-sericin biomatrix as a good candidate for soft tissue reconstruction and wound healing applications. © 2013 by the authors; licensee MDPI, Basel, Switzerland.

A layer-by layer technique was successfully used to obtain collagen/hydroxyapatite-magnetite-cisplatin (COLL/HAn-Fe3O4-CisPt, n=1-7) composite materials with a variable content of hydroxyapatite intended for use in the treatment of bone cancer. The main advantages of this system are the possibility of controlling the rate of delivery of cytostatic agents, the presence of collagen and hydroxyapatite to ensure more rapid healing of the injured bone tissue, and the potential for magnetite to be a passive antitumoral component that can be activated when an appropriate external electromagnetic field is applied. In vitro cytotoxicity assays performed on the COLL/HAn-Fe3O4-CisPt materials obtained using a layer-by layer method confirmed their antitumoral activity. Samples with a higher content of hydroxyapatite had more antitumoral activity because of their better absorption of cisplatin and consequently a higher amount of cisplatin being present in the matrices.
