Ultrafiltration membranes offer a progressive and efficient means to filter out various process fluids. The prime factor influencing ultrafiltration to a great extent is the porosity of the membranes employed. Regarding membrane development, alumina membranes are extensively studied due to their uniform porosity and mechanical strength. The present research work is specifically aimed towards the investigation of nanoporous alumina membranes, as a function of sintering parameters, on ultrafiltration performance. Alumina membranes are fabricated by sintering at various temperatures ranging from 1200–1300 °C for different holding times between 5–15 h. The morphological analysis, conducted using Scanning electron microscopy (SEM), revealed a homogeneous distribution of pores throughout the surface and cross-section of the membranes developed. It was observed that an increase in the sintering temperature and time resulted in a gradual decrease in the average pore size. A sample with an optimal pore size of 73.65 nm achieved after sintering at 1250 °C for 15 h, was used for the evaluation of ultrafiltration performance. However, the best mechanical strength and highest stress-bearing ability were exhibited by the sample sintered at 1300 °C for 5 h, whereas the sample sintered at 1250 °C for 5 h displayed the highest strain in terms of compression. The selected alumina membrane sample demonstrated excellent performance in the ultrafiltration of sugarcane juice, compared to the other process liquids.

This paper discusses the attitudes and opinions of research scientists and engineers to taking part in public understanding of science activities. A survey was carried out at an event in set95 (the UK's 1995 National Week of Science, Engineering and Technology), which involved 168 scientists from the University of Bristol, UK, taking their research work into a shopping mall in Bristol for two days. All participating scientists and engineers were asked to complete a written questionnaire shortly after the event and then at least one participant from each display was contacted seven months later for telephone interview. The results show that while most of the scientists took part because they were told to by senior colleagues, after the event almost all (94 per cent) wanted to take part again mainly because they had found the experience enjoyable. Despite the demands of time and organization, individuals benefited from taking part; participants felt it improved their presentation skills and enhanced morale. They regarded the exhibition as good for communication skills training and did not want formal training for the event. The exhibition was also valued as a team-building exercise both within individual departments and across the University.

Introduction. Ukraine in the Russian Empire and in Soviet times, as you know, occupied a leading position in the production of beets and sugar. But until 1997, Ukrainian beet growers did not have their own professional Ukrainian-language print publication, although there was an urgent need for it. The industry journal Sugar Beet, which, in fact, became the first communication platform in Ukraine for the implementation of production-scientific and educational-explanatory functions related to the development of beet-growing and bioenergy, was founded in 1997. Sugar Beet was one of the first journals in independent Ukraine in 1998 to be included in the List of Professional Scientific Publications of Ukraine Recommended for the Publication of the Main Results of Doctoral and Candidate's Dissertations in the Department of Agricultural Sciences. The key place in the columns of the publication was occupied not only by sugar beets (Beta vulgaris), but also by the coverage of research work related to the launch of the process of moving some dual-application crops in the research fields and research laboratories of the institute located on Batyi Hill, and some new and until recently little-known for Ukraine so-called ‘energy’ crops (sugar sorghum, miscanthus, switchgrass, Sudan grass, salix, etc.), in special bioenergy plantations to obtain biomass and process it into various types of energy, which later stimulated and, in fact, symbolized a breakthrough in terms of forming a new independent bioenergy (phytoenergy) industry in Ukraine. 1076 original research and production articles were published in the columns, the authors of which are not only scientists and practitioners of the crop industry, but creators of high-yielding varieties in Ukraine and abroad – in Russia, Kazakhstan, Germany, Switzerland, Belarus and others. countries; At the same time, each 5–6 articles published under the headings such as Non-traitional Crops, Biotechnology, Breeding and Genetics, Agrotechnology or Bioenergy directly or indirectly covers the problems of development of so-called special ‘energy’ plants. A section on world and domestic trends in the development of renewable and non-traditional energy sources has found a permanent residence on the pages of the journal. Conclusion. The study shows that one of the oldest scientific and production editions – Sugar Beet – has played an important and timeless role not only in the development of the beet and sugar industry, but also in the history of bioenergy. Its issues are still available online on the official website of the IBCSB (see journal.sugarbeet.gov.ua.).

And Behavior

The development of new technologies in recent years has highlighted interdisciplinarity as a tool to solve complex problems faced by scientists and engineers in research work. Worldwide, the area of space science, specifically astrobiology, has had more than 25 missions with high technological development and economic returns. However, the success of interdisciplinary teams requires collaboration, responsibility, and leadership on the part of all members to prioritize the main objectives of the research. Likewise, the formation of interdisciplinary teams can be affected because there is little information about the strategies and tools that recognize the opportunity for constant interaction between subjects from engineering and science. Using a known methodology based on other recent proposals, we include a description of the conformation and behavior of a research team and an analysis of interdisciplinarity through the interrelation and level of dependence of the existing subject categories in the “Killalab” team. In this research, we present the ensemble interdisciplinary group “Killalab” and its implications for the realization of astrobiological investigations.

Abstract The waste water generated from sugar industry contains a high degree of organic pollutant. Treating the sugar industry wastewater is thus crucial important for the environmental concern. The treated water can be reprocessed in different unit operation due to lack of fresh water. The purpose of this research work is to treat the sugarcane processing industry wastewater by electrochemical technology. The experiment was carried out with the copper electrode in batch mode. The input process parameters were optimized by using response surface methodology. At optimum condition at pH 6.79, current 4.97, electrode distance 1.41 and treatment ∼30 min, maximum 87.07% of chemical oxygen demand and 99.18% color removals was attained. A fairly high predicted value of regression coefficient for chemical oxygen demand (Pre-R 2) 0.81 and color (Pre-R 2) 0.851 and adjacent value for chemical oxygen demand (Adj-R 2) 0.46 and color (Adj-R 2) 0.589 was obtained between the experimental values and the calculate values by using a second-order regression model. The physicochemical characterizations of scum reveal less percentage of inorganic and it cane used as a micronutrient.

Some notes on the history of psychology in Brazil, in terms of undergraduate and postgraduate training, provide a background for the understanding of present trends in research, teaching and practice in the field of behavioural development. Research work on any aspect of psychology in Brazil is closely intertwined with postgraduate programs. Most of them began in the seventies and are concentrated in the south-eastern regions of the country. The two basic theoretical influences on research are behaviourism and cognitivism, although an ethological orientation is evident in several recent studies. A review of the work of various research groups indicates great progress in behavioural studies during the last few years. An action-oriented approach clearly prevails, involving work with underpriviledged and mentally retarded children. The rate of scientific production measured in terms of published papers and books, however, remains extremely low. Efforts are being made to improve the scientific communication system, although serious limitations are imposed by the difficult economical situation of the country.

Tourism Resources

Tourism is often considered as a vehicle for community development and poverty alleviation and it is recognized as an off-farm activity that is key in generating revenue and providing employment for poor rural and urban residents and promoting economic growth in those communities. Community-based tourism has been advanced as a bottom-up strategy that encourages more just and equitable benefits for local communities to meet their household needs. Despite tourism's potentials in community development, this is a contested topic and needs both theoretical and applied research. This article provides an overview of tourism and community development research and offers future directions. With articles from across the globe, this special issue brings to the fore achievements as well as challenges experienced in different settings as different stakeholders engage in tourism with a view to develop host communities. Eleven articles published in the special issue highlight theoretical, practical, and policy implications and therefore have the potential to advance knowledge in the field. This volume contributes to the tourism and community development discourse by providing diverse theoretical and empirical pieces of research work that will provide knowledge, inform practitioners, community development planners, and policy makers in their efforts to assist destination communities, in both the Global North and the Global South, to use tourism resources and attractions in a sustainable manner to improve their livelihoods.
