This paper aims to analyze the sustainability of E-learning of the university education system in Vietnam, specifically FPT University, during the Covid 19 epidemic. In the case of FPT University in this research, the students and teachers and managers from the Business Administration department, who are already familiar with online learning methods, gave information about their perspectives about the sustainability of E-learning based on Environmental, Economic and Social aspects. Furthermore, the lecturers, students, and managers concluded the best sustainable learning method among Synchronous Asynchronous, and Blended Learning. Moreover, some recommendations to sustain E-learning are proposed to strengthen the E-learning system in Vietnam. Qualitative research is applied in this study to find out the sustainability of E-learning in Vietnam.

Abstract. By combining AVHRR data from the NOAA satellites with information from a database of in situ measurements, large-scale maps can be generated of the microphysical parameters most immediately significant for the modelling of global circulation and climate. From the satellite data, the clouds can be classified into cumuliform, stratiform and cirrus classes and then into further sub-classes by cloud top temperature. At the same time a database of in situ measurements made by research aircraft is classified into the same sub-classes and a statistical analysis is used to derive relationships between the sub-classes and the cloud microphysical properties. These two analyses are then linked to give estimates of the microphysical properties of the satellite observed clouds. Examples are given of the application of this technique to derive maps of the probability of occurrence of precipitating clouds and of precipitating water content derived from a case study within the International Cirrus Experiment (ICE) held in 1989 over the North Sea.

Assessment Approach

Not every Business Excellence model has an integral approach considering the environmental, economic, and social aspects of sustainability. The aim of the paper is to review the selected Business Excellence Models and to introduce a proposal to improve this type of models as being applicable for the sustainability assessment. The models that were chosen are used as a basis for organisational improvement. The paper is based on information gathered through extensive literature review (research publications, research studies, documents about The Business Excellence Models) using Internet and research databases and the author’s own experience. Methods of analysis, comparison, selection and statistics are to be used. Although the models are based on similar principles, the differences are in the number and structure of the criteria, respectively, sub-criteria and in the sustainability assessment approach. Therefore, as key criteria in the area of self-assessment, we propose seven non-results criteria and criterion results. The proposed Model is discussed with the analysed models, based on the calculation of their mutual distances. The model, which is closest to the proposed model, is The Singapore Business Excellence Framework.

Insight Into

AbstractMonitoring ice motion provides insight into the relative contributions of atmospheric and oceanic forcing to polynya dynamics In this study ice kinematics in the North Water (NOW) region, northern Baffin Bay Canadian Arctic are determined using time-sequential RADARSAT-1 ScanSARWide imagery (from the period January-December 1998), processed by the automated ice-tracking algorithm (Tracker) currently used at the Canadian Ice Service (CIS). A case-study is then carried out on the Smith Sound region from January till the end of june 1998 to monitor polynya formation, maintenance and disintegration. This has two objectives: (1) to evaluate satellite ice-motion products as a means of better understanding the relative contributions of latent- and sensible-heat mechanisms responsible for the formation and behaviour of the NOW polynya, and (2) to study the influence of winds on regional sea-ice motion. Derived ice-motion maps were validated using in situ ice beacons deployed onto floes in the NOW region during the 1998 ship-based science experiment. Tracker-derived displacement and directional regressions were 0.93 and 0.79, respectively, with a total standard error of 3.6 km in magnitude and 38.8° in direction. Analysis of monthly mean ice-motion maps shows that a significant export of ice occurs from the polynya. A comparison of weekly-averaged ice motion with the mean wind-field data suggests that ice export in Smith Sound is influenced by synoptic-scale atmospheric pressure systems.

The Impact

AbstractCompanies awareness of the impact generated by its products increases and motivates them to develop initiatives to improve their sustainability. In this work, a methodology consisting of three main phases: sustainability assessment, redesign process and comparison of designs, is proposed to obtain more sustainable product designs. Methodology is based on the Life Cycle Sustainability Assessment (LCSA) approach, which is applied to simultaneously evaluate environmental, economic and social aspects. In the case study the sustainability improvement of the furniture of a clothing retail store is addressed. A set of indicators are considered to evaluate the sustainability performance of both initial design and redesign. The study concludes that the application of different sustainability strategies allows a significant enhancement of the environmental and economic indicators.

Abstract Background The technique of symbiotic germination—using mycorrhizal fungi to propagate orchids from seed in vitro—has been used as one method to cultivate orchids in North America and abroad for > 30 years. A long-held assumption is that mycorrhizal fungi used for this purpose lose their effectiveness at germinating seeds over time with repeated subculturing. Results We provide evidence for the lingering efficacy of one particular strain of Tulasnella calospora (266; UAMH 9824) to stimulate seed germination exemplified by the North American terrestrial orchid, Spiranthes cernua, as a case study. This fungus was originally acquired from roots from Spiranthes brevilabris in 1999 and sub-cultured during the two decades since. Seeds inoculated with the fungus in vitro developed to an advanced protocorm stage after 16 days, and leaf elongation was pronounced after 42 days. In a pilot study, seedlings co-cultured with Tulasnella calospora 266 were deflasked after 331 days and later transferred to soil under greenhouse conditions where they eventually initiated anthesis. During the course of two decades, seeds of 39 orchid species, cultivars and hybrids spanning 21 genera, germinated in vitro co-cultured with Tulasnella calospora 266. These orchids included temperate terrestrials and tropical epiphytes alike. Conclusions The sustained effectiveness of this fungus is noteworthy because it argues against the concept of mycorrhizal fungi losing their symbiotic capability through prolonged subculturing. This study serves as an example of why in situ habitat preservation is essential for the conservation of orchids as a source of potentially useful mycorrhizal fungi.
