Typical performance behavior of a Diesel cycle agricultural tractor engine with electronic injection management and turbocharger

ABSTRACT: Over the past few years, changes have been observed in the behavior of typical performance curves, after higher technology has been incorporated into the agricultural tractor engines, either to satisfy the ceiling of the new pollutant gas emission limits or to achieve better efficiency. The aim of this study was to assess the typical performance behavior of an agricultural tractor engine, possessing electronic injection management, turbocharger, aftercooler and EGR (Exhaust Gas Recirculation) treatment system. An analysis was done of the information the manufacturers provided, in terms of nominal power, maximum power and maximum power with Booster, maximum torque and maximum torque with Booster. From the results, the percentage difference between the nominal power and maximum power were found to hover anywhere from 1.49 to 11.97%, for the same manufacturer, 0% in another manufacturer and 9% in a third manufacturer, for all the models. Similar results were noted for the data reported on the maximum torque and maximum torque with Booster, giving 0.62% as the minimum value, 7.44% as the average value and 12.65% as the maximum value for the entire series.

Understanding and Assessing Cultural Intelligence: Maximum-Performance and Typical-Performance Approaches

Cultural intelligence is one’s ability to adapt when confronted with problems arising in interactions with people or artifacts of diverse cultures. In this study, we conduct an initial construct-validation and assessment of a maximum-performance test of cultural intelligence. We assess the psychometric properties of the test and also correlate the test with other measures with which it might be expected there would be some connection. We found that our test was internally consistent and correlated significantly with maximum-performance tests of abilities but generally less or not at all with typical-performance tests, including cultural intelligence and openness to experience. However, our test appears to be distinct in what it measures from the other tests of cognitive abilities. The results lead us to suggest that cultural intelligence may have both maximum-performance and typical-performance aspects.

Operable partitions - a life of experiences, observations, and testing plus comments on standards

Experiences testing operable partitions since 1986 will be reviewed including typical performance and various problems observed with both the partitions and surrounding structures. ASTM standards E557 on proper building preparation for an operable partition and E336 for the measurement of field performance will be discussed, including the 2005 revision of E336 as it affects evaluation of operable partitions.

Physiotherapy Students’ Performance in Clinical Education: An Analysis of 1 Year of Canadian Cross-Sectional Data

Purpose: This research examines 1 year of cross-sectional, Canada-wide ratings from clinical instructors using the Canadian Physiotherapy Assessment of Clinical Performance (ACP) and analyzes the performance profiles of physiotherapy students’ performance ratings over the course of their entry-to-practice clinical placements. Method: Canadian physiotherapy programmes that use the ACP were invited to submit anonymized, cross-sectional data for placements completed during 2018. Descriptive analyses and summary statistics were completed. Mixed-effects modelling was used to create typical performance profiles for each evaluation criterion in the ACP. Stepwise ordered logistic regression was also completed. Results: Ten programmes contributed data on 3,290 placements. Profiles were generated for each ACP evaluative item by means of mixed-effects modelling; three profiles are presented. In all cases, the predicted typical performance by the end of 24 months of study was approximately the rating corresponding to entry level. Subtle differences among profiles were identified, including the rate at which a student may be predicted to receive a rating of “entry level.” Conclusions: This analysis identified that, in 2018, the majority of Canadian physiotherapy students were successful on clinical placements and typically achieved a rating of “entry level” on ACP items at the end of 24 months.

Effects of Natural Weathering on the Performance of High Solar Reflective Index Paint Surfaces Exposed in Harsh Climatic Conditions of United Arab Emirates

Solar reflective index (SRI) is one of the important parameters in the analysis of a building&rsquo;s energetic and thermal performance, especially for &ldquo;cool&rdquo; reflective paints or coatings. However, there exists less information on the typical performance of the cool materials exposed for long term in the Middle East and more specifically in the United Arab Emirates (UAE). In this study, we determined values of reflectance, emittance, solar reflective index (SRI), and color difference, for three different high SRI white paints exposed naturally on low and high sloped racks for three years. After 3 years, reflectance values of exposed paint panels significantly decreased with an increased color difference in comparison with original unexposed paint surfaces. Emissivity of the paint changed very little for all of the exposed samples, but SRI, determined from both the reflectance and emittance, was reduced from between 95 and 110 to between 60 and 90 after three years. This appeared to be related to exposure to high temperatures, UV radiation, and adhesion of airborne contaminants in conjunction with low precipitation. Macroscopically, panels exposed on a low slope were the most discolored with the greatest presence of dust infusion and reduction in increase in surface temperatures which was demonstrated through thermal imaging. Such natural weathering research study is necessary for the development of standard exposure tests and determination of various control elements to increase the durability of cool materials in hot and arid climatic conditions of UAE.

Institutional repositories in Africa: Regaining direction

Institutional repositories are powerful tools to facilitate global access to intellectual output by members of the institution, particularly in assisting them to preserve and maximize access to their research output globally. This exploratory study of the status of institutional repositories implementation in African countries using the global Directory of Open Access Repositories (OpenDOAR) and Transparent Ranking: All Repositories by Google Scholar, reports on the operational status and the performance of repositories. Factor analysis and cluster analysis are used to analyze the operational level of institutional repositories in African countries. The analysis showed that the typical performance of institutional repositories remains below average. The possibility of global open access to research results through institutional repositories in South Africa, Kenya, Nigeria, Algeria, Sudan, and Egypt appeared to be relatively more feasible than other African countries. This study concludes that many organizations, institutions, and societies spend great efforts in support of open access implementation in Africa, however, the widespread implementation of institutional repositories is still very slow paced, and the performance of the implemented repositories was below expectation. Suggestions for regaining the intended direction of African institutional repositories are given based on the current status.

Recent Development: Enantioselective Extraction in Chiral Separation

This paper discusses the recent development of enantioselective extraction methods. There are several methods in this field. The principles of all of enantioselective extraction methods are presented a focus on twophase extractions, in these methods used a chiral compound that named chiral selector, this compound distinguishes between two chiral isomers in complexation process, then one isomer more captured by chiral selector, and separation processes happen. The chiral selector should dissolve in on phase. In these methods, typical performance data are reported major emphasis on distribution ratio and enantioselectivity value or selectivity factor. In this paper, we introduce types of enantioselective extraction method, and discuss about them with several examples.
