Opis:
Today consumers are becoming more aware of the need to protect the environment, and companies use these terms to promote their goods or services with eco-labels. Environmentally friendly (also eco-friendly, nature friendly, and green) are terms used to refer to goods and services, laws, guidelines and policies claiming to inflict minimal or no harm on the environment. Clothing is an integral part of our lives and green or environmental concerns have started to draw more and more attention in the textile and clothing sector . This paper analysed how green the textile and clothing industry is with respect to the product lifecycle, from raw material through the design, production and logistics up to disposal in order to point out important points and parameters for greening the industry.
W dzisiejszych czasach konsumenci stają sie coraz bardziej świadomi potrzeby ochrony środowiska, firmy natomiast korzystają z tego w celu promowania swoich towarów i usług za pośrednictwem znaków certyfikacyjnych. "Przyjazny środowisku" to termin odnoszący się do produktów, usług i procesów, które w minimalnym stopniu zagrażają środowisku. Odzież jest integralną częścią naszego życia, dlatego coraz więcej uwagi poświęcane jest sprawom ochrony środowiska w sektorze tekstylno-odzieżowym. W artykule przeanalizowano wpływ ochrony środowiska w przemyśle tekstylno-odzieżowym w odniesieniu do cyklu życia produktu, od surowca poprzez projektowanie, produkcję i logistykę, aż do gospodarki odpadami w celu wskazania czynności ważnych dla przemysłu z punktu widzenia ochrony środowiska.

Opis:
A cold roll-bonding process was applied to fabricate an AA1050/AA6061/AA1050 multi-layer sheet. Three Al sheets in which an AA6061 sheet is inserted inside two AA1050 sheets of 2 mm thickness, 40 mm width and 300 mm length were stacked up after surface treatment, and the material was then reduced to a thickness of 1.0 mm by multi-pass cold rolling. The AA1050/AA6061/AA1050 laminate complex sheet fabricated by roll bonding was then hardened by a natural aging (T4) and an artificial aging (T6) treatments. The microstructures of the as-roll bonded and the age-hardened Al complex sheets were revealed by optical microscope and electron back scatter diffraction analysis, and the mechanical properties were investigated by tensile and hardness testing. The strength of the as-roll bonded complex sheet was found to increase by 2.6 times, compared to that value of the starting material. Both AA1050 and AA6061 showed a typical recrystallization structure in which the grains were equiaxed after heat treatment. However, the grain size was smaller in AA6061 than in AA1050.

Opis:
Recently lack of sustainable management for the reservoir watershed becomes a predicament for the water issues in Taiwan. The study tried to recognize the framework of the sustainable management of the Taiwan reservoir watershed and its key factors by using the analytic hierarchy process and the Delphi method. Through the identification questionnaires and the CVM (contingent valuation method), it also discussed the gap of expert and public for the identification of satisfaction, environmental protection and the potential value for the recent reservoir watershed. However, the results showed that the “natural stability” is the significant factor in the first level and the “Nature resources conservation” and “Water storage amount” are the most important factors for the detailed level. In addition, the expert opinions were not proved by public identification, and the present governance budgets are too low to respond to the potential values of public expectancy.
W pracy przedstawiono wyniki badań przeprowadzonych dla określenia hierarchii ważności czynników ekologicznych, ekonomicznych i socjalnych związanych ze zrównoważonym zagospodarowaniem zlewni zbiorników wodnych na Tajwanie. W badaniach zastosowano metodę ankietową, w której respondenci stosując pięciostopniową skalę mieli wskazać ważność 22 określonych przez ekspertów czynników związanych z ochroną i zrównoważonym korzystaniem z zasobów środowiska, wpływających na standard życia mieszkańców oraz możliwości rozwoju gospodarczego na obszarze zlewni zbiorników wodnych. Stwierdzono, że najważniejsze znaczenie dla ludności mają czynniki ekologiczne, w szczególności zapewnienie stabilności przyrodniczej poprzez zachowanie bioróżnorodności oraz ochrony zasobów naturalnych, w tym ilości retencjonowanej wody.

Opis:
Many countries are formulating organic agriculture or organic farming policies aimed at sustainable agricultural development. Therefore, the objectives of this study were: to understand the present situation of organic agriculture policies in Sri Lanka and also in other countries where successful organic agriculture is operating; identify problems in the organic agriculture sector; and suggest potential policy measures to be implemented in Sri Lanka in future. The research was conducted in two stages. In the first stage, a thorough literature review was conducted to study the suitable policies available in other countries and also in Sri Lanka at present. In the second stage, two field surveys were carried out using pre-tested questionnaires, from December 2019 to May 2020, in order to gather farmers’ and extension officers’ information related to organic farming policy suggestions. According to the findings of the literature review, organic systems in some countries are more integrated with national strategic plans and visions. Those governments are more involved in new initiatives and farmers are encouraged to go organic through reliable and feasible policies. Although Sri Lanka has a high potential for organic agriculture, at present it is at an initial stage. While most organic products in Sri Lanka go to the export market, a small portion is kept at local markets. Demand for organic products in export as well as domestic markets is increasing. Even though there are seven international food certification agencies operating in the country as external inspection and certification bodies, a limited number of accredited certifications exist for products on the domestic market. Results of the farmers’ survey showed that even if farmers have a significant level of knowledge, few of them practice organic farming due to several existing problems. Moreover, extension officers have also identified similar types of problems that are faced by the farmers related to organic farming. Evaluation of Strengths, Weaknesses, Opportunities and Threats (SWOT) related to organic agriculture in the country helped to identify key problems facing policy-makers when balancing the supply and demand sides of organic products. Also, in developing organic agriculture, an effective linkage and coordination among government and private participants is crucial. Therefore, in Sri Lanka in this context, strategic focus on policy support for organic agriculture is needed. Current organic farming programs need to be revised in order to formulate policies covering all areas related to production, handling, processing, certification, labeling and marketing, in order to bring the benefits of organic agriculture to farmers, marketers and consumers in a fair manner.

Opis:
The Upper Ordovician sedimentary succession of southeast Ireland is riddled with almost synsedimentary igneous intrusions. A study was required to determine any effects of these intrusions on Kübler Index (KI) so that further sampling for a regional study could be undertaken and the results would be unbiased. Sampling was carried out on the low-grade metapelites (Southeast Ireland) around the rhyolitic and doleritic intrusions, which were intruded into the still soft sediment. Clay mineralogy was determined using X-ray diffractometry and KI values were measured; SEM and whole rock elemental analyses were applied to complement the results of the XRD work. KIs immediately around rhyolitic intrusions were observed in all cases to be lower than the regional KI, however this was not seen around doleritic intrusions. SEM work shows illite grain sizes following the KI trend and K2O were noted to be highest where KI was lowest. Rare earth elements (REEs) show some mobilization which also follows the KI trend. This is considered to be a residual effect of hydrothermal fluids / volatiles hosted by the rhyolites but not encountered in the dolerites. Chlorite crystallinity is not affected as it most likely crystallized after the hydrothermal event. The KI is often used as a proxy for illite crystallinity in studies of low grade metamorphism but is influenced by many parameters and care should be taken when applying this technique to studies of regional metamorphism.

Opis:
A technique for pattern classification using the Fourier transform combined with the nearest neighbor classifier is proposed. The multidimensional fast Fourier transform (FFT) is applied to the patterns in the data base. Then the magnitudes of the Fourier coefficients are sorted in descending order and the first P coefficients with largest magnitudes are selected, where P is a design parameter. These coefficients are then used in further processing rather than the original patterns. When a noisy pattern is presented for classification, the pattern’s P Fourier coefficients with largest magnitude are extracted. The coefficients are arranged in a vector in the descending order of their magnitudes. The obtained vector is referred to as the signature vector of the corresponding pattern. Then the distance between the signature vector of the pattern to be classified and the signature vectors of the patterns in the data base are computed and the pattern to be classified is matched with a pattern in the data base whose signature vector is closest to the signature vector of the pattern being classified.
