Report - Usability and Anthropometrics for ROWENTA Intensium Bagless Assignment

Report - Usability and Anthropometrics for ROWENTA Intensium Bagless Vacuum Cleaner - Assignment Example By the end of the report a clear evaluation of the appliance achieved by experimenting it with users will be covered. The report also offers an analysis of performance in regard to ergonomic principles. Although, it is widely thought that bag-less vacuums were developed just the recently, the features have been in use since time immemorial.  The previous vacuums, for example used bag-less qualities until about three decades ago, when the feature was discarded.   The manufacturers abandoned making bag-less vacuums on hygienic grounds.   The usability of such appliances was low.  One had to remove the bag part off and empty the dirt in the garbage. This was a daunting task, especially when a dustbin or refuse disposal was not near.  Additionally, the appliance’s use over time would result in the clogging of the filtration in the bag, following more dust accumulation (Gavriel, 2012). Most users were prompted to wash the cloth bag in order to achieve adequate efficiency when the cloth had become dirty.  The current world has, however, seen the comeback of the bag-less vacuum. Rowenta Intensium Bag-less Vacuum Cleaner is arguably one such equipment that is as well-lik ed as before due to its effective usability qualities. According to Gavriel (2012), the primary reason behind the widespread use of the appliance is that one does not need to purchase vacuum bags to operate it. This implies more savings on the part of the user.  Additionally, as the chamber in which dirt collects becomes increasingly filled with dirt, it should just be removed and emptied in the refuse bin.  Another advantage of using the Rowenta appliance is that any more accumulation of dirt in the chamber does not impact its continued functionality, and that one can practically read the amount of dirt being absorbed by the vacuum cleaner, hence the ease to tell whether the appliance is functioning well, and the level of dirt

Genetically Modified animal-to-human xenograft Term Paper

Genetically Modified animal-to-human xenograft - Term Paper Example The present article discusses the perception about xenotransplantation as an opening for a better future and the fact that for others, it signifies a move towards one more AIDS-like epidemic. The article discusses research, debate and also the decisions in this area of science. Xenotransplantation, as the name suggests, is a kind of transplantation that is performed between two different species; it encompasses transplantation of living cells, tissues or organs, usually as transplantation from non-human animal species into humans. This could be from mouse to humans or from pig to humans. The transformed tissue or organs are known as xenografts/ xenoplants. On the other hand, if the transplantation is performed between two similar species, then the process can be referred as allotransplantation. With the increasing population, there is an increase in demand for health care and facilities that performs these procedures. It is not currently possible to perform allotransplantations. Moreover, a great number of patients in anticipation of getting organ replacement die on before they get the alternative organ or tissue. There is an augmented demand for allotransplants of heart, kidney and liver, and the most feasible method sought to fulfill the enhanced demand is xenografts. This is of critical interest to those whose ailing lives are on the verge of death and who are still waiting for any donated organ or tissue. A survey was performed to take an assessment from patients regarding their understanding of types and techniques of transplant. The results display that around 75% of respondents knew about xenografting; of these 50% were ready to accept a xenograft for self and 43% for relative; 10% found a xenograft to be intolerable. On the other hand 40% were uncertain and wanted to know about the technology (Arundeii,, 1996). Only 27%
