Additionally, it shows a brief history of cooperative development on Polish lands and statistical data on agriculture and cooperatives. Most attention is given to dairy cooperatives, cooperative groups of agricultural producers and agricultural production cooperatives. These types of cooperatives are the most popular in Polish agriculture. The fundamental law regulating the issue of cooperatives in Poland is the Cooperative Law Act of September 16, 1982. Other laws, however, also have a big influence on the business activity of agricultural cooperatives, especially the EU legal regulations. Poland membership in the European Union has created new possibilities of development for the cooperative movement.展开更多

A host country's societal and cultural factors, combined with local economic conditions and business practices, play major roles in determining the preferred business ethics and social responsibility in each foreign subsidiary. An MNC's global HQ should partner with all foreign subsidiaries to determine the global corporate business ethics, social responsibility core, general values, and objectives. Further, each foreign subsidiary should develop in partnership with the HQ, the customized details of its business ethics, social responsibility objectives, goals, strategies, and specific programs for its host country's environment.展开更多

In particular, the existence and the uniqueness of Nash Equilibrium(NE) strategies for noncooperative mode are proved. In addition, a distributed iterative algorithm is proposed to obtain the optimal solutions of the scheme. Simulation studies are carried out to show the performance comparison between two modes as well as the system revenue improvement of the proposed scheme compared with a conventional scheme without a virtual price control factor.展开更多

HINT is a two-year project part funded Geoparks researching the uses and benefits of new technologies in by the European Leader Programme. The partners are Geopark Shetland (Scotland), Chablais Geopark (France), North Pennines Area of Outstanding Natural Beauty (England) and Geopark de Hondsrug (The Netherlands). Each partner has developed a pilot project to investigate the practicalities of interpreting and communicating heritage, especially geological heritage, using a particular technology. An overview of each of the four pilot projects is given. The overall aim of the pilot projects is to develop best practice in using new technologies for heritage interpretation and to share information and ideas within the project partnership and with geoparks and heritage organizations around the world. This paper, developed by the HINT partners, aims to give an insight into the practical process of developing interpretive tools using new technologies. Some common problems are highlighted and some ways in which these can be addressed are shown.展开更多

These structures are extensively employed in building construction industry due to their light mass, ductility by economic cold forming operations, favorable strength-to-mass ratio and other factors. The utilization of cold formed steel sections with concrete as composite can hugely reduce the construction cost. However, the use of cold formed steel members in composite concrete beams has been very limited. A comprehensive review of developments in composite beam with cold formed steel sections was introduced. It was revealed that employing cold-formed steel channel section to replace reinforcement bars in conventional reinforced concrete beam results in a significant cost reduction without reducing strength capacity. The use of composite beam consisting of cold-formed steel open or close box and filled concrete could also reduce construction cost. Lighter composite girder for bridges with cold-formed steel of U section was introduced. Moreover, types of shear connectors to provide composite action between cold-formed steel beam and concrete slab were presented. However, further studies to investigate the effects of metal decking on the behavior of composite beam with cold-formed steel section and introduction of ductile shear connectors were recommended.展开更多

In this paper, based on the fluid-solid coupling theory, we built the stress-seepage coupling model for rock, then we combined with an example of water-inrush caused by fault, studied the water-inrush mechanism by using the numerical software COMSOL Mutiphysics, analyzed the change rule of shear stress, vertical stress, plastic area and water pressure for stope with a fault, and estimated the water-inrush risk at the different distances between working faces and the fault. The numerical simula- tion results indicate that: (1) the water-inrush risk will grow as the decrease of the distance between working face and the fault; (2) the failure mode of the rock in floor with fault is shear failure; (3) the rock between water-containing fault and working face failure is the reason for water-inrush.展开更多

AM can be considered as one of the latest innovative processes, as a state-of-the-art development, in manufacturing industries. AM is expressed as the future of the products and localization of the manufacturing processes in some studies. Innovation is a key factor both for firms and consumer products or service output. And, in today's competitive environment, it compels all the partners for R & D activities to provide technological development. But, all the partners come to a parting of the ways of disruptive or sustainable innovation. It can be said that furniture manufacturing by AM method is relatively new. Non-industrial use of the AM in furniture production can be stated as one of the latest innovative development. Thereby, this study reviews how AM is used to produce furniture within applied projects, which materials and methods are used for production and suggests its future impact.展开更多

This paper analysed the production process of the agro industrial cooperative producers of macadamia nut (Coopmac), located in the town of Sao Mateus-ES/Brazil, and responsible for the production and marketing benefits for the states of Espirito Santo and Bahia. This analysis was performed in order to identify new opportunities for developing new products. The following steps were explored: analysis of the current procedure, ideas generation, analysis of potential ideas, development of a product concept and development of a prototype product. In cooperative, macadamia oil was only extracted. It was decided to develop a potential product from this oil. Initially, chemical analyzes were performed with this oil and opted for the production of soaps, liquid and bar. During this step, the methodology of design of experiments was used to develop the prototype. Sensory analysis, based on the LAM type hedonic scale, was used in the tests. The data were analyzed and could be distinguished the best formulation and the main effects for each assessed parameter. In this step, the statistical analysis software was used. From the value of the overall quality of the sample, greater acceptance for liquid soaps was obtained for a formulation with lower oil volume and higher volume of amphoteric. When concerning the sample bar soaps, the best formulation had the lower ratio of oil volume, the higher volume of amphoteric and lower mass of clay. The authors expect to contribute to generation of scientific and technological knowledge in order to effectively meet the practical needs of efforts directed to the production of macadamia nuts in the state of Espirito Santo.展开更多

Genetic screens have identified in the last decade many far-red light signaling mutants and several red and blue light signaling mutants, suggesting the existence of distinct red, far-red, or blue light signaling pathways downstream of phytochromes and cryptochromes. However, genetic screens have also identified mutants with defective de-etiolation responses under multiple wavelengths. Thus, the opti- mal de-etiolation responses of a plant depend on coordination among the different light signaling pathways. This review intends to discuss several recently identified signaling components that have a potential role to integrate red, far-red, and blue light signalings. This review also highlights the recent discoveries on proteolytic degradation in the desensitization of light signal transmission, and the tight connection of light signaling with photoperiodic flowering and circadian rhythm. Studies on the controlling mechanisms of de-etiolation, photoperiodic flowering, and circadian rhythm have been the fascinating topics in Arabidopsis research. The knowledge obtained from Arabidopsis can be readily applied to food crops and ornamental species, and can be contributed to our general understanding of signal perception and transduction in all organisms.展开更多
