Thermal conductivity

The thermal conductivity constant of the material (k) is glass, which found in the physics textbook is .80 J/smC° (Cutnell, 2012). Using a meter ruler, I measured the length of my window as 1.70 m and the width as 1.10 m. When multiplying these two values to find the…

2.1 Preparation of inoculum The hydrogen producing anaerobic sludge containing mixed microflora was collected from the bottom of the anaerobic pond located at Felda Palm Oil Industry, Lepar Hilir, Gambang, Malaysia. To enrich the sludge with hydrogen producing bacteria and inhibit the bioactivity of methanogens, the sludge was heat treated at 90°C for 60 minutes [21]. The treated anaerobic sludge was used as inoculum for the hydrogen production. The acclimated inoculum has a 4.6 g-SS/L…

COMPARATIVE STUDY ON FRICTION WELDED AND ELECTRON BEAM WELDED JOINTS MADE BY 20VNiMoCr120 STEEL Gabriela IANCULESCU*, Lucia Violeta MELNIC, Marian Andrei GURĂU Ovidius University of Constanta Abstract: In the paper there are presented experimental results concerning mechanical characteristics of friction-welded joints in comparison with electron beam welded joints, made by 20VNiMoCr120 heat-resistant steel, which are part of some elements working at high pressure and temperature. The paper…

The aim of the Stress Concentration Experiment was to observe the stress concentration factor/feature for a set of mild steel specimens with various irregularities in each sample. These irregularities or “stress-raisers” include any notches and holes which vary in size (radius) and placement on the specimen (edge notches or holes) that may have an effect on the flow of stress. With the use of a Hounsfield 50 kN electrically operated tensile testing machine and 12 1-mm thick mild steel test…

While the increase in pollution levels leads to more incidences of respiratory illnesses, another impact of the urban heat island on public health. 2.3.2 Thermal comfort These raised temperatures in city centre derive from the altered thermal balances in urban spaces, mainly due to the materials and activities taking place in cities, by far different to those in rural areas. The increasing numbers of buildings and construction in Ipoh caused that…

Abstract—This paper aims at briefly discussing the various techniques used in tactile sensing and then compares them. Next, different types of commercial tactile sensors, along with suitable performance criteria for their comparison are discussed. Finally, currently existing commercial sensors are talked about in detail, including the leading manufacturers, their products and the description of their data sheet. Keywords— Artificial skin; Commercial; Sensors; Tactile. I. INTRODUCTION The word…

CHAPTER II. REVIEW OF THE RELATED LITERATURE A. Temporary Magnet Temporary magnets are those that essentially demonstration like permanent magnets when they are inside a strong magnetic field (Jezek, 2015). They are not like permanent magnets when it's not around in a magnetic field because it loses its own magnetism. Temporary magnets cannot remain magnetized on their own (Boyer 2017). Paperclips, press nails, and other comparative things are cases of temporary magnets. Temporary magnets are…

Earth is composed of many different components such as minerals, and rocks. These components have several different properties and characteristics which are unique to each. In this paper, I will discuss some of the different properties, characteristics, and uses of three different factors, those being gypsum, coal, and nickel. Gypsum Gypsum is derived from the Greek word gypsos which means plaster (Gypsum Meanings, Powers, and History). Gypsum is composed of oxygen, calcium, sulfur, and water…
