Main Effects

Short Cycle Stretch Forming (SCS) is an innovative stretch forming technology developed at the Institute for Metal Forming Technology (IFU) at the University of Stuttgart. The SCS technology combines plane pre-stretching of blank and subsequent deep drawing operations within the same stroke of press ram. The sheet metal thickness is reduced while denting resistance and yield stress increases due to hardening effects.Current research work focuses on applying SCS-technology to rotational-symmetrical bodies. A process simulation for SCS-Cupping process was performed for food cans. Based on these results a tool was manufactured and commissioned. The results showed that the thickness of cup bottoms of two-piece drawn and ironed (D&I) steel cans can be reduced. Therefore, it is possible to save material costs in serial production based on a reduced blank diameter.In this paper the different effects leading to the thinning of steel can bottom and failure types, such as, wrinkling and cracking are observed in a number of experimental series. Based on these results, the tool geometry was optimized and an advanced tool was manufactured. The results of this paper show that SCS-Cupping offers promising potential to save material, as well as outlining the main effects for this technology.

Main Effects

Short cycle stretch forming (SCS) is an innovative stretch forming technology, developed by the Institute for Metal Forming Technology (IFU) at the University of Stuttgart. The SCS technology combines plane pre-stretching and deep drawing operations within the same stroke of the press ram. The sheet metal thickness is reduced, and the denting resistance as well as the yield stress are increased due to hardening effects.In this study, the SCS technology is applied to rotational-symmetric bodies. A process simulation of an SCS cupping process was carried out for producing tinplate cans. Based on these results, a tool was produced. First results showed that the metal thickness of cups for two-piece drawn and ironed (D&I) steel can bottoms can be reduced. With this technological goal, it is possible to save the material cost in series production.This paper analyses how batch fluctuations affect the thinning of cup bottoms in SCS cupping. Therefore, preliminary experiments have been conducted, using their results to improve the previously used FE process model. With the aid of this model, an FEA-based parametric study on the variation of material properties is conducted. To examine batch fluctuations, tensile tests have been taken into account, and initial material parameters for simulation, such as friction coefficient, initial blank thickness, Lankford parameter and hardening behaviour, have been varied.The results of this paper show that SCS cupping offers a promising potential for material savings and demonstrate the main effects of batch fluctuations.

The burgeoning area of plant genetics may hold the key to overcoming some of the most pressing environmental challenges. For example, crops can be genetically improved to make them better able to adapt to climate change, while genetic engineering of crops could help to address food security challenges. As such, a comprehensive understanding of plant genetics may enable humankind to make headway in addressing climate change and resulting challenges. Research in this area is therefore paramount. Research work undertaken in the Plant Transgenic Design Initiative (PTraD) in the Gene Research Center (GRC) within Tsukuba Plant Innovation Research Center (T-PIRC), located at the University of Tsukuba in Japan, is focused on plant sciences and biotechnologies. The PTraD is the centre of excellence in plant biotechnology research in Japan, shedding light on plant genetics and how this can be harnessed to solve environmental challenges such as climate change.

Source Of Information

In October 1968, the University of Ghana commenced an extensive program in African archaeology. Graduate students from overseas are eligible to enroll for courses at the University, though no scholarships are presently available for non-Ghanaians. The Department of Archaeology of the University of Ghana was established in 1951 under the professorship of A. W. Lawrence. It presently has a senior teaching establishment of four together with a curator and two senior research fellows under the chairmanship of Professor Merrick Posnansky. The Department has a small specialist library, a museum, laboratory, dark room, workshops, and a team of trained technical staff. Most of the Department's research work is normally conducted in the dry season from November to May each year. In the past Professor Oliver Davies, author of the Quaternary of the Guinea Coast (1964) and West Africa before the Europeans (1967), conducted extensive fieldwork relating to the Stone Age and neolithic periods of Ghana's past and made large surface collections from all parts of Ghana which provide a rich topographical source of information on archaeology in Ghana. The Department has conducted extensive excavations in Ghana and its research fellows are presently engaged in writing up the results of the Volta Basin Research Project, in which more than thirty sites have been excavated since 1963 in advance of the formation of a large lake consequent upon the construction of the Volta Dam. The majority of the excavated sites have been of Iron Age date. In September 1968, Mr. C. Flight commenced a new season of excavations at “Neolithic” rock shelter sites at Kintampo, where occupations and burials dated to the middle of the second millennium B.C. were uncovered in 1967. Other excavations conducted during 1968 included work by Mr. D. Calvocoressi at the funerary terracotta site of Ahinsan and by Mr. Duncan Mathewson at the seventeenth-century A.D. Gonja site of Jakpasere. In 1969 a training excavation will be conducted at Elmina on the sixteenth- to eighteenth-century A.D. town in the vicinity of the Portuguese castle.

The contents of Education for Sustainable Development should be included in teachers’ initial and advanced training programs. A sustainable consciousness is one of the main foundations for determining the key competences for sustainability. However, there are not many empirical studies that deal with consciousness from education. In this context, the e-portfolio appears as a tool that promotes reflection and critical thinking, which are key competences for consciousness development. This work intends to propose a categorization system to extract types of consciousness and identify the levels of consciousness of teachers in training. For this research work, which is of an eminently qualitative nature, we have selected 25 e-portfolios of students (teachers in pre-service training) in the last year of the School of Education at the University of Macerata (Italy). The qualitative methodological procedure that was followed enabled deducing three bases that shape the consciousness of teachers in training: thinking, representation of reality, and type of consciousness. We concluded that the attainment of a sustainable consciousness in teachers requires activating and developing higher levels of thinking, as well as a projective and macrostructural representation of reality.
