An Experimental Study on the Pressure Range of Fire Cupping Method

Background: Standardized procedures for the clinical application of fire cupping methods have not been established. In particular, the pressure parameters have not been fully characterized and described. Therefore, using various materials, this study investigated the pressure range exerted during fire cupping therapy. Methods: In this study, 3 differently sized (small, medium, large) glass and bamboo cups were used in the cotton ball fire cupping procedure to measure the pressure inside the cup applied to a human skin model. The pressure in each cup was measured 15 times for a total of 90 measurements. Results: A small bamboo cup had the minimum overall pressure (-305.4 mmHg), whereas the large glass cup exerted the maximum pressure (-401.3 mmHg), followed by the medium glass cup, large bamboo cup, small glass cup, and medium bamboo cup. The average pressure exerted by the cotton ball method for all cups ranged from -348.715 mmHg to -358.694 mmHg (95% confidence interval). Overall, the glass cups had a greater pressure than the bamboo cups in all groups (p < 0.001). Among the glass cups used, the larger the size of the cup, the higher the average pressure detected (-381.947 mmHg to -391.973 mmHg; p < 0.05). Conclusion: Large glass cups which are widely used in clinical practice, when used in the fire cupping method exerted pressure ranging from -381.947 mmHg to -391.973 mmHg (95% CI).

Design And Development Of An External Glass Wall Cleaning System

The increasing number of skyscrapers calls for an increasing demand for regular maintenance and cleaning of the large glass panes or windows of these buildings. Cleaning these windows, is not only tough and a risky job but also time consuming. Thus, an effort has been made to introduce a new system which not only reduces the human effort but also aims in cleaning the windows effectively as well as efficiently. This project aims to produce a clean view through the windows which helps in maintaining the aesthetic view of the building. This device can be used periodically for efficient cleaning of the external glass walls, as there is no involvement of a human being suspended from the top of the building. The Current device can be used as a replacement for an existing method in order to ensure safety of the workers.

Keratoconic and (de)formed vision: Re-thinking the limits of perspectival drawing

In this project the limitations of perspectival drawing are revised and reconsidered through a particular visual (dis)ability: keratoconus. Perspectival representation is based not only on a single and immobile eye, but also on an ‘able’ eye. The de-formation of keratoconic vision offers a new means to consider the perspectival drawing by extending beyond the limitations of its structure. The degenerative keratoconic eye thus calls attention to the intricate mechanism of sight and to the eye’s machinic functioning. By referring to Creative Evolution by Henri Bergson and The Large Glass by Marcel Duchamp it becomes possible to articulate the nuanced relations between the complexity of the eye as a complex structure and the simplicity of its unitary function. Through keratoconic vision, one experiences the formations and (de)formations of the visual image due to the eyes’ functioning and dysfunctioning. This then leads to the search for an alternative medium that is similar to such a nuanced embodied visual experience. The interval between the machinations of vision and the simplicity of its function is more closely resembled through the visual experience of the stereoscope. The digitization of the stereoscope further unfolds this notion of the durational interval that lies between the machinations of vision and their unitary function, increasingly veering towards the former. Emerging digital stereoscopic imaging begin to utilize feedback and interaction and thus produce new ways to imagine the complexity of the eye(s) and visuality more broadly.

Early medieval large glass beads from Poland: utilitarian and social functions

The study focuses on the early medieval large glass beads from the area of Poland, i.e. specimens whose diameter equals at least 1.5 cm but usually ca. 2 cm or more. The main aim of this study is to define their function, considering precise context of discovery of particular specimens, metric data and microscopic analyses. Another important task of the study is to determine whether large beads were local products or imports, and from which region and in what social circumstances they reached the studied area. Alongside macroscopic and stylistic features, chemical composition of glass that was used for production of the beads can be conclusive in this situation. In our opinion, it is a special category of finds that appeared in this part of Europe during the time of cultural and political transformation in the 11th–13th centuries.

Evaluation of Thermal Comfort and Energy Consumption of Water Flow Glazing as a Radiant Heating and Cooling System: A Case Study of an Office Space

Large glass areas, even high-performance glazing with Low-E coating, could lead to discomfort if exposed to solar radiation due to radiant asymmetry. In addition, air-to-air cooling systems affect the thermal environment indoors. Water-Flow Glazing (WFG) is a disruptive technology that enables architects and engineers to design transparent and translucent facades with new features, such as energy management. Water modifies the thermal behavior of glass envelopes, the spectral distribution of solar radiation, the non-uniform nature of radiation absorption, and the diffusion of heat by conduction across the glass pane. The main goal of this article was to assess energy consumption and comfort conditions in office spaces with a large glass area by using WFG as a radiant heating and cooling system. This article evaluates the design and operation of an energy management system coupled with WFG throughout a year in an actual office space. Temperature, relative humidity, and solar radiation sensors were connected to a control unit that actuated the different devices to keep comfortable conditions with minimum energy consumption. The results in summer conditions revealed that if the mean radiant temperature ranged from 19.3 to 23 °C, it helped reduce the operative temperature to comfortable levels when the indoor air temperature was between 25 and 27.5 °C. The Predicted Mean Vote in summer conditions was between 0 and −0.5 in working hours, within the recommended values of ASHRAE-55 standard.
