Non-newtonian Rabinowitsch Fluid Effects on the Lubrication Performances of Sine Film Thrust Bearings

Thrust bearings are generally developed to sustain axial load generated from rotating machinery. Predicting lubrication performances of thrust bearings plays an important role in engineering applications. Taking into account the effects of non-Newtonian rheology, the lubrication performances for a sine film thrust bearing are investigated in the present paper. By employing a small perturbation technique to the nonlinear non-Newtonian Reynolds equation, analytical solutions of the film pressure, the load-carrying capacity, the friction parameter and the required volume flow rate are derived. Comparing with the case lubricated with a Newtonian lubricant, the non-Newtonian Rabinowitsch fluids (including the pseudo-plastic fluids and the dilatant fluids) show significant influences on the lubrication performances of a sine film thrust bearing, especially for a larger value of the non-Newtonian parameter.
IS CANADA'S AGGREGATE PRODUCTION FUNCTION COBB-DOUGLAS? ESTIMATION OF THE ELASTICITY OF SUBSTITUTION BETWEEN CAPITAL AND LABOR

Based on U.S. data, Antris (2004) illustrates that the assumption of Hicks-neutral technological change necessarily biases estimates of the elasticity of substitution between capital and labor towards one, given Berndt's (1976) specification. Modifying the specification to allow for biased technological change, he obtains significantly lower estimates of the elasticity. Using Canadian data, I obtain similar results. This suggests that a Cobb-Douglas specification of Canada's aggregate production function may be misleading.

Training as the Principal Focus of Adjustment Policy: A Critical View from Northern Ontario

This is a regional case study of the effects of training on labour market adjustment following mass layoffs in a single-industry mining community, Elliot Lake in Northern Ontario. Based on longitudinal survey data we find that training programs as a whole had limited benefits to the laid-off workers, particularly in terms of re-employment, although longer-duration programs at the college level appeared more effective. This is not a call to cut funding for training, which can have important social and psychological benefits for laid-off workers and their families; but it is a criticism of the current approach that makes training the principal focus of adjustment policy, at least as it plays out in single-industry communities like Elliot Lake.
Heritability, variance components and genetic advance of some yield and yield related traits in Ethiopian collections of finger millet (Eleusine coracana (L.) Gaertn.) genotypes

Eighty-eight (88) finger millet ( Eleusine coracana (L.) Gaertn. ) germplasm collections were tested using augmented randomized complete block design at Adet Agricultural Research Station in 2008 cropping season. The objective of this study was to find out heritability, variance components, variability and genetic advance for some yield and yield related agronomic characters. Statistically significant (p<0.01) difference was observed among the genotypes tested for important characters indicating the presence of variability. A considerable amount of variability among germplasms for the traits studied also indicated the usefulness of selection for these traits in the genetic material used for future improvement in finger millet. In addition, high genotypic coefficient of variation (GCV) was recorded for number tillers per plant (71.93), number of ears per plant (96.55), number of fingers per ear (85.48), finger length (94.48), biomass yield (87.67), and grain yield (78.17) and high phenotypic coefficient of variation (PCV) was similarly recorded for number tillers per plant (30.42), number of ears per plant(45.55), number of fingers per ear (24.88), finger length (26.18), biomass yield (85.56), and grain yield (29.87). High heritability coupled with high expected genetic advance as percent of mean was obtained for number of ears per plant (96.55, 90.59%), number of finger per ear (85.48, 43.81%), finger length (94.48, 50.95%), and days to heading (96.01, 14.13%), biomass yield (87.67, 154.52%), 1000 kernel weight (93.69, 37.70%), lodging susceptibility (98.92, 384.24%) and blast severity (87.60, 89.47%) indicating that the presence of more additive gene effects for potential crop improvement and so these characters could be improved through selection. This study reveals that greater yield response could be obtained through direct selection scheme in finger millet landraces. Keywords : Eleusine coracana, finger millet, genotypic coefficient, phenotypic coefficient, variance, heritability, genetic advance, Ethiopia.

Mechanistic Study of the Wettability Modification in Carbonate and Sandstone Reservoirs during Water/Low Salinity Water Flooding

The paper pertains to the analysis of the chemical interaction between sea water ions, asphaltene colloids and silicate /calcite mineral as a substrate during water/low salinity water flooding. The work tackles modeling of salinity dependent relative permeability and capillary pressure functions from contact angle to estimate oil recovery during water/low salinity water. The paper has two main parts. In the first part, static contact angle is calculated based on disjoining pressure and compared to the experimental values, reported in the literature. In the second part, the model is used to demonstrate that water film is more stable in presence of low salinity water compared to distilled water and sea water, for carbonate and silicate minerals. Increasing temperature enhances the stability of the water film around the substrate for both types of minerals. This could be future interpreted as an indication for extra oil recovery applying low salinity water injection at elevated temperature. It is interesting to observe from the model that, increasing the Mg2+ ion concentration enhances the hydrophilicity characteristics for calcite mineral modified by asphaltene while for silicate surface modified by asphaltene, SO42- ion enhances the hydrophobicity behaviour.
Calculation of Steel Pipeline Corrosion Depth at the Galvanic Corrosive Element Operation

The work is devoted to the issue of calculating the safe life of steel pipelines, which is in accordance with the definition of the residual thickness of the pipe wall.The purpose of this work is to develop a dependence, permitting to calculate the corrosion depth of the steel pipeline in the crack of the insulation coating under the action of an electrolytic medium aggressive to the pipeline metal. To achieve this goal, the following tasks were solved: to develop a dependence based on the mathematical model of a local corrosion element, that would allow to calculate the steel pipeline corrosion depth in the crack of the insulating coating, which would be based on real parameters obtained during the structures examination; to conduct an experimental verification of the steel pipeline’s corrosion damage depth during the galvanic corrosion element’s operation.Based on the mathematical model of the pipeline’s electrochemical corrosion in the crack of the insulating coating under the action of an the electrolytic medium aggressive to the pipeline metal, a dependence was obtained permitting to calculate the depth of the pipeline’s wall corrosion during the work of the macro-galvanic corrosion couples and the stable presence of an aggressive solution in the damaged zone. The experimental studies have proved that direct corrosion tests are consistent with the design values of the macro-galvanic couple’s current. The advantage of this model is the ability to predict the development of corrosion in time, regardless of the aggressive electrolyte’s chemical composition, the possibility of obtaining the required calculation parameters using the structures operated.
Empathy Versus Price: The Influence of Emotional Appeals Across Cultures

This research examines the persuasive effect of emotional appeals on members of collectivist versus individualist cultures. The results of two experiments demonstrate that ego-focused (e.g., pride, happiness) versus other-focused (e.g., empathy, peacefulness) emotional appeals lead to more favorable attitudes for members of a collectivist culture, while other-focused versus ego-focused emotional appeals lead to more favorable attitudes for members of an individualist culture. Experiment 2 was conducted to examine the psychological mechanism underlying these effects. The results indicated that the generation of and elaboration on a relatively novel type of thought (individual thoughts for members of a collectivist culture, collective thoughts for members of an individualist culture) account for the persuasive effects found in this research. These results are interpreted within an ability-motivation framework, and theoretical implications involving cross-cultural persuasion effects are discussed.

Life Style Related Risk Factors of Type 2 Diabetes Mellitus and Its Increased Prevalence in Saudi Arabia: A Brief Review

Aims: Role of life style related risk factors is very important in the pathogenesis and progression of Type 2 Diabetes Mellitus. The aim of this article is to review the disease burden of Type 2 diabetes mellitus (T2DM) among the population of Saudi Arabia due to unhealthy life style. Methods: In this review, the information was collected from published literatures related to risk factors like unhealthy dietary pattern and sedentary life style leading to T2DM. Additionally, some epidemiological information for the prevalence of T2DM in Saudi Arabia was also collected. Results: Earlier studies have depicted that unhealthy life style and dietary patterns are risk factors involved in the development of insulin resistance in the body cells. In Saudi Arabia, rapid economic growth has provided a luxurious life style to the masses eventually leading to decrease in the physical activities and adoption of unhealthy dietary patterns. The increased prevalence of T2DM in Saudi Arabia is very much implicated to the life style related risk factors which needs to be improvise for the prevention of this disease. Conclusion: Since the increased prevalence of T2DM is associated with the sedentary life style and unhealthy dietary pattern, so it is recommended that creating awareness about the life style related risk factors for T2DM among general population and patients, will effectively contribute in lowering its incidence rate.
Noise Power Ratio testing of multichannel single sideband communication equipment

It is shown, that Noise Power Ratio (NPR) testing of mul tichannel Single Sideband (SSB) transmitters should be perform ed loading all channels with identical white, gaussian, zeromean noise signals in order to obtain the worst case result. A theoretical analysis of bichannel equipment under the two different input conditions* (a) statistically independent noise signals, and (b) statistically dependent noise signals? shows that the intermodulation distortion on the output of the transmitter is the same for either case. This result is extended for an arbitrary number of chan nels to the point of showing that the test results obtained for statistically dependent noise inputs will be either equal to or worse than those obtained for statistically independent noise inputs. The theoretical conclusions made for a bichannel transmit ter are verified by means of practical measurements performed on such a transmitter. 4 . ) '. \ f, ,', p; J. J.
Scanpath visualization and comparison using visual aggregation techniques

We demonstrate the use of different visual aggregation techniques to obtain non-cluttered visual representations of scanpaths. First, fixation points are clustered using the mean-shift algorithm. Second, saccades are aggregated using the Attribute-Driven Edge Bundling (ADEB) algorithm that handles a saccades direction, onset timestamp, magnitude or their combination for the edge compatibility criterion. Flow direction maps, computed during bundling, can be visualized separately (vertical or horizontal components) or as a single image using the Oriented Line Integral Convolution (OLIC) algorithm. Furthermore, cosine similarity between two flow direction maps provides a similarity map to compare two scanpaths. Last, we provide examples of basic patterns, visual search task, and art perception. Used together, these techniques provide valuable insights about scanpath exploration and informative illustrations of the eye movement data.
ScienceDirect The 2014 conference of the International Sports Engineering Association Impact-absorbing materials in reducing brain vibration caused by ball-to-head impact in soccer

There has been a long debate among researchers on whether soccer heading is capable of causing brain trauma. A recent study suggests that headings exceeding a threshold level of 855 to 1,550 per year, results in microstructural abnormalities in the brain’s white matter. This shows that brain trauma is caused by cumulative effect of repetitive headings. The use of protective headgear is one of the suggested preventive measures to protect the brain especially for younger players. Researchers have tested several commercial headgears and found that they are only effective in head-to-head impact, but ineffective in attenuating impact caused by heading. This is due to the fact that soccer ball is compliant in nature relative to the head. The aim of this study is to investigate materials that can be utilised to minimise the acceleration of the brain caused by soccer heading. A vertical drop ball test was conducted on an instrumented dummy skull. The inner cavity of the skull is filled with ultrasound gel that represents the brain. Six impact-absorbing materials were tested to determine the most effective material that reduces the acceleration of the brain substitute. The speed of the ball before and after impact as well as impact duration were measured using high-speed camera. Coefficient of restitution was calculated to ensure the material is not only capable of reducing the brain acceleration, but also maintains heading performance. It was found that polymer kneepad foam is the most effective material that minimises the acceleration of brain substitute whilst maintaining the speed of the ball after impact. © 2014 The Authors.

Water on graphene: review of recent progress

The sensitivity of graphene to the surrounding environment is given by its π electrons, which are directly exposed to molecules in the ambient air. The high sensitivity of graphene to the local environment has shown to be both advantageous and problematic for graphene-based devices, such as transistors and sensors, where the graphene carrier concentration and mobility changes due to ambient humidity variations. In this review, recent progress is presented in understanding the effects of water on different types of graphene: epitaxially grown and quasi-free standing on SiC(0 0 0 1), grown by chemical vapour deposition and transfered on SiO2, and exfoliated flakes. It is demonstrated that water withdraws electrons from graphene, but the graphene–water interaction highly depends on the thickness, layer stacking, underlying substrate and substrate-induced doping. Moreover, we highlight the importance of clear and unambiguous description of the environmental conditions (i.e. relative humidity) whenever a routine characterisation for carrier concentration and mobility is reported (often presented as a simple figure-of-merit), as these electrical characteristics are highly dependent on the adsorbed molecules and the surrounding environment.
Competitive Proposals to Special Interests

We consider electoral competition between two political candidates. Each can target private benefits to some groups. A candidate has an incentive to offer high benefits in the initial period, to deter the other candidate from offering yet higher benefits to the same group in a later period. We describe the equilibrium strategies of the candidates, showing that candidates will intend to target different groups, that groups targeted in the initial period gain larger benefits than groups targeted later, and that the benefits to special interests vary with their number and size.
APPAREL RETAILERS USE OF STORE ATMOSPHERICS: A STRATEGIC MOVE OR A WASTED APPROACH?

The retail industry has been a central part of everybody’s livesand apparel retailers are no different than other retailers. The basic practices of retailing have changed over the past years due to a number of reasons, least of all due to the changing technological environment, the changing market needs and demands, as well as the increasingly globally competitive market retailers have to deal with. The fact that the time duration between these changes are continuously becoming shorter and shorter has negated the benefits that the standard four p’s used to offer retailers. Retailers need to make use of other ways and means to differentiate themselves and to stay ahead of their competitors. This phenomenon has led to this study which focuses on the influence that store atmospherics has on consumers’ buying behaviour. Store atmospherics and its influence on consumers’ buying behaviour is an area that has received very little attention in the literature to date. The primary research aim of this study was to explore the influence of store atmospherics on consumers’ buying behaviour in apparel retail stores in the Tshwane region. The type of research design used in this study was exploratory in nature, making use of a qualitative approach and a communicative technique, including focus group interviews and naïve sketches. The data gathered was analysed by means of Tesch’s inductive descriptive coding technique, better known as thematic analysis. It was found that atmospheric elements have the ability to influence consumers either in a subconscious or a conscious way. This has a direct influence on the amount of time the consumers will spend in-store and ultimately the amount of money spend in the store. The study also pointed out that consumers’ buying behaviour and the decision to buy or not will be influenced, indicating that the consumers will display either an approachor avoidance behaviour.
Activity-based costing of canned and processed foods businesses in Thailand: effects on organizational development, business competitiveness and corporate success

This study aims at investigating the relationships among activity-based costing, organizational development, business competitiveness, and corporate success of canned and processed foods businesses in Thailand. In this study, 142 canned and processed foods businesses in Thailand are the samples of the study. Structural equation model (SEM) was employed to test the research relationships. The research results indicate that activity-based costing positively leads to organizational development and business competitiveness. Also, organizational development positively relates to business competitiveness and corporate success while business competitiveness positively affects corporate success. In summary, activity-based costing plays a significant role in determining, driving and explaining firm outcomes. Accordingly, firms need to pay attention to the development and utilization of activity-based costing through the provision of competencies, capabilities, resources, and assets to its implementation. To verify the current study, future research may need to search for activity-based costing’s dimensions and components, collect data from different populations and countries and apply regression analysis, partial least squared and path analysis to prove the relationships.
Interlocking directorships and patenting coordination

ABSTRACT The aim of this paper is to investigate the role interlocking directorships play in the patenting activities of UK companies and provide further insights into the channels through which this relationship emerges. We develop a theoretical model that identifies interlocking directorships as a mechanism for resolving property rights conflicts. Our empirical analysis suggests a strong relationship between interlocking and patenting behaviour and finds that interlocking leads to a higher number of successful patent applications, particularly for those firms located in technology-intensive industries.
