Surfaces

work have attracted a fair amount of attention from scientist and practitioners over the past decades. One of the topics is emotional labour which was introduced by Hochschild (1983). The concept of emotional labour has many aspects to it such as surface acting, deep acting, intensity of emotional display, the duration of emotional display, range of emotional display, automatic emotion regulation and many more. Their effects on an employee’s work satisfaction, their self-esteem and psychological…

Solution growth deposition This technique consists essentially of inserting the substrate into a solution containing hydrolysable metal compounds and pulling it out at a constant speed into an atmosphere containing water vapour. In this atmosphere, hydrolysis and condensation takes place. Finally the films are hardened by a high temperature cycle to form transparent metal oxides. Any hydrolysable compound including halides or nitrates but preferably metallo-organics are suitable…

the main objectives of this study is to discuss the surface tension effect, according to thermosolutal Marangoni convection effect, on the motion. The increase of the temperature surface tension parameter and the concentration surface tension parameter means a decrease in the surface tension according to the negative values of the coefficients and . So, the reduction of the surface tension, at the free surface, reduces the free surface rigidity…

The lung wall is delicate which makes it susceptible to surface tension injury. The wall is made of epithelium, which is tissue that lines the cavities and surfaces of organs in the body. When complications with infections occur regions of the lung can fill with fluid, also babies born premature can have underdeveloped lungs causing increased surface tension. These cause the lungs to remain closed, a disease called respiratory distress syndrome. The deformation of biological cells when…

impervious surfaces. “Impervious surfaces are mainly constructed surfaces--rooftops, sidewalks, roads, and parking lots--covered by impenetrable materials such as asphalt, concrete, and stone” (Barnes, Morgan, and Roberge 3). Every new roofed structure, every new sidewalk, and every new road adds a new water blockade. This seal of man made material slowly covering the earth prevents water from infiltrating into the soil and replenishing supplies of ground water. Impervious surfaces also…

process. The conclusion to objective four states that the farmer’s capacity to adapt is very limited due to the various daily obstacles faced including lack of resources, information, financial capacity and lack of support from the government. Lack of surface water for crop production remains the most serious limitation to adaptive capacity, followed by inability to access farm credit services and improved…

Discussion: Mudboils cause structural failures since they are suspensions of gravel, clay, silt and fine sand creating an unstable surface. Since the beginning of persistent mudboil activity in the 1970’s, natural landscapes and engineered features have become subject to land-subsidence as mudoils continually deteriorate the areas in their path (Tresohlavy 2003, pp. 27). Petroleum pipeline rerouting, telephone cable burials, and the collapse of bridges have demonstrated the true capabilities of…

Surfactant Agents I. Definitions a. Surfactant: A surface-active agent that lowers surface tension i. Examples 1. soap 2. detergent b. Surface Tension: Force caused by attraction between like molecules that occurs at liquid-gas interfaces and that holds the liquid surface intact i. Units of Measure: dynes/centimeter (dyn/cm) 1. the force required to cause a 1 cm rupture in the surface film ii. a droplet forms because a liquid’s molecules are more attracted to each other than the surrounding…

Freshwater management has been of major concern in New Zealand, particularly during the last two decades. There has been consistent decline in water quality and quantity in Canterbury during this time. Consequently, work has been made to improving the way water resources are managed. This report will discuss the consent conditions for the Lincoln University Dairy and Research Farms, consent number CRC143396, and how the consent is monitored. The Resource Management Act (1991), the Dairying Clean…

A mudflow is a flowing mixture of debris and water, usually moving down a channel. Flow is divided into categories, depending on the amounts of water involved. Slump occurs when a mass of regolith slides over or creates a concave surface (one shaped like the inside of a bowl). The result is the formation of a small, crescent shaped cliff, known as a scarp, at the upper end. Soil flow takes place at the bottom end of the slump. One is likely to see slumps in any place where forces…
