The number of consumers with green awareness have grown these days and as a result they have turned to purchase eco-friendly products. For this reason, this study aims to propose a method for eco-design based on the anticipatory failure determination method to develop eco-design products. By using eco-design concepts adopted from the World Business Council for Sustainable Development, the process will limit the failures and issues related to environmental impact in product design. The proposed method for eco-design product in this study follows the following procedure. First, we analyze product failure. Second, we propose the determination of the non-green phenomenon of the failure. Thirdly, we integrate the intensified non-green phenomenon to generate non-green hypotheses and fourthly, we eliminate each non-green phenomenon hypothesis by introducing the contradiction matrix of TRIZ for obtaining solutions. Finally, we assess alternative eco-design solutions by evaluation. To verify the practicality of the new procedure, a washing machine is used as an example for illustration.

Copper slag is a massive metallurgist waste. Annual production rises up to 24.6 million tons, approximately, and the main environmental impact derived from slag disposal is the usage of great soil extensions and the resulting visual contamination of the landscape. Along time, copper slag has been used in the manufacture of concrete and cement mortars. Thus, with the aim of verifying binder-type influence in the final hardness of mortars, two types of cement were used: regular cement and high initial resistance cement. Copper slag was characterized from the chemical, mineralogical and grading viewpoints. Official Chilean regulations were used in the applied methodology for the determination of some important slag parameters. Compression and flexural strength trials were carried out on cement mortars in specialized laboratories. The obtained results showed that mortars manufactured with copper slag presented a better resistance to compression and flexural strength than mortars manufactured with normal sand, and those made with high initial resistance cement were even better. It can be concluded from this work that copper slag offers optimal mechanical characteristics to be used in the manufacturing of cement mortars, becoming a sustainable and adequate alternative material for usage in the construction industry.

Introduction. Erectile dysfunction (ED) combines many conditions leading to erectile dysfunction and disability to perform sexual intercourse. It was confirmed that the most common cause of ED is vascular disorders, primarily associated with atherosclerosis that leads to cardiovascular diseases. Objective. To analyze the available literature data about the methods for diagnosis vascular ED, including according to cardiovascular system status. Materials and methods. The results of the search in scientific databases Medline, EMBASE, Cochrane, Chinese BioMedical Literature Database, China National Knowledge Infrastructure, Elibrary.ru were analyzed. After a detailed verification of the reliability of sources, impact factors of journals and the sequence of presentation of the material, 63 most relevant scientific publications were selected directly for citation. Results. The first step of the vascular ED diagnosis is the monitoring of nocturnal penile tumescences. Next, the risk factors for cardiovascular diseases and ED are evaluated: anamnesis of elevated blood pressure, physical activity, smoking, body weight, measurement of blood pressure, blood analysis with the lipid and glycemic profiles. For the diagnosis of endothelial dysfunction (END), the determination of flow-dependent vasodilation of the brachial artery is used, with the possible determination of the rate of blood filling after decompression. After the END is confirmed in patients with ED, it is useful to determine the vascular age using the SCORE scale. For further management of the patient with ED and END, stratification of the associated with sexual activity cardiovascular complications risk is recommended. Conclusion. The proposed diagnostic algorithm will allow not only identify the vascular component of ED at an early stage, but also to avoid fatal cardiovascular complications by prescribing and recommending therapeutic and preventive measures to patients with asymptomatic cardiovascular diseases.
