Abstract:

Effective workshop management skills are vital for the occupational safety of the students, lecturers, instructors, support staff, or technicians who use mechanical production or manufacturing workshops at universities. The main purpose of the paper is to examine the status of the undergraduate university students’ skills practice in safety management in the engineering educational workshops assess the common occupational hazards and risks in the workshops, and explain the prospects of promoting occupational safety standards. The paper was informed by a recent study that was done in Kyambogo University, Uganda with a focus on employable skills outputs. The paper objectives were to identify the safety measures to be used in skills practice, design precautionary signs for skills practice, implement safety measures for skills practice in the department of mechanical production Engineering. In the study, a descriptive research design was used, where both qualitative and quantitative research methods were used. The total number of respondents who participated in the study was 30. The respondents included the head of the department, lecturers, students, technicians from the Mechanical Production Engineering Department of Kyambogo University. Data were collected from respondents through the use of questionnaires and interview guides. Data were analyzed and presented using tables and then descriptions were done using percentages. The findings revealed the following occupational hazards and risks, physical hazard, ergonomic hazards, chemical hazards, psychological hazards, and biological hazards. The study also revealed that accidents always occurred in the department of mechanical and production workshops. The major causes of the accidents were due to lack of knowledge or skills, safety policy gears, carelessness, safety protective wears, proper storage of materials, and instructions’ manuals or guidelines. In addition, there are problems of lack of modern tools, digital technology, good supervision, adequate space, and awareness of the ICT led safety systems. The cost-cutting strategies for workshop safety management were warning signs, alerts, and clear labels, use of protective gear, providing first aid kits, vocationalised training, and awareness campaigns on occupation safety. There is a need for routine monitoring, renovations, replacing obsolete machines, safety tags, fire drills, industry-university benchmarking, or industrial placements

Abstract:

Results of investigations concerning membrane bioreactor aeration are presented which were carried out at the Institute of Environmental Engineering of RWTH Aachen University (ISA) in cooperation with the Department of Chemical Engineering of the Technische Universität Berlin. In the field of industrial and municipal wastewater treatment the use of membrane bioreactors (MBR) is of increasing interest especially due to the high requirements on effluent quality nowadays. The design of aeration systems is a very important aspect of MBR development because it influences both cost of operation and filtration flux. The ISA has carried out tests concerning the velocity flow pattern in flat sheet membrane modules (developed by the A3 Water Solutions GmbH) to identify the effects of different aeration systems, aeration intensities and module constructions. The Department of Chemical Engineering is currently using the results obtained from the ADV to calibrate a numerical model which simulates two phase water and gas flow within an aerated membrane module. Optical investigations concerning the bubble distribution give a better understanding of the flow conditions in MBR. Developing a numerical tool for membrane module optimization concerning the hydrodynamics is the aim of the investigation of membrane bioreactor aeration.

Abstract:

Abstract The article presents results of pitting corrosion studies of selected silicon cast irons. The range of studies included low, medium and high silicon cast iron. The amount of alloying addition (Si) in examined cast irons was between 5 to 25 %. Experimental melts of silicon cast irons [1-3] were conducted in Department of Foundry of Silesian University of Technology in Gliwice and pitting corrosion resistance tests were performed in Faculty of Biomedical Engineering in Department of Biomaterials and Medical Devices Engineering of Silesian University of Technology in Zabrze. In tests of corrosion resistance the potentiostat VoltaLab PGP201 was used. Results obtained in those research complement the knowledge about the corrosion resistance of iron alloys with carbon containing Si alloying addition above 17 % [4-6]. Obtained results were supplemented with metallographic examinations using scanning electron microscopy. The analysis of chemical composition for cast irons using Leco spectrometer was done and the content of alloying element (silicon) was also determined using the gravimetric method in the laboratory of the Institute of Welding in Gliwice. The compounds of microstructure were identify by X-ray diffraction.

Abstract:

The 12th International Conference on High Temperature Materials Chemistry (HTMC-XII) took place at the Vienna University of Technology, Austria, 17-22 September 2006. Previous conferences were held in 2000 in Juelich (Germany), and in 2003 in Tokyo (Japan).The conference was sponsored by IUPAC and organized by the Department of Inorganic Chemistry/Materials Chemistry of the University of Vienna together with the Austrian Chemical Society (GÖCH) and the Department of Materials Chemistry of the Vienna University of Technology. The local organizing committee was chaired by Profs. Adolf Mikula and Herbert Ipser of the University of Vienna. Special patronage was granted by the Austrian Federal Minister for Education, Science and Culture and by the mayor of Vienna.More than 150 participants from 25 countries worldwide came to Vienna to present their research in the field of high temperature materials chemistry and to interact with each other in a lively scientific discussion. A considerable number of scientists, especially from Russia and some Eastern European countries, had the chance to come to this conference for the very first time, partly due to partial financial support by the local organizers, for example, by reduced or waived registration fees. It was also a pleasure to see many young scientists who made new contacts with each other and with their senior colleagues from all over the world.The program contained nine plenary lectures, corresponding to the main topics, but also included two special lectures on topics of more general interest, such as "Do universities prepare for industrial careers" (by Knuth Consemüller, chairman of the Austrian Council for Science and Technology Development), and "The arts: What use to materials science" (by Mark Miodownik). The plenary lectures, with the exception of the lecture by Dr. Consemüller, are published in this issue.In addition, there were 51 oral presentations and 100 posters that were on display for the entire week.For this conference, IUPAC sponsored three poster awards, and the winners received a two-year subscription of Chemistry International, a copy of the IUPAC "Gold Book" as well as a certificate signed by the IUPAC president. The winners, as selected by an international jury, were Dario Manara of Italy ("The uranium-oxygen phase diagram at high temperature: Recent advances"), Yuriy Plevachuk of Ukraine ("Density and electrical conductivity of liquid Al-Fe and Al-Ni binary alloys"), and Jiři Popovic of the Czech Republic ("Thermodynamic optimization of the Ni-Al-W system").The social program included a reception in the City Hall of Vienna, sponsored by the mayor of Vienna, as well as a conference excursion to the easternmost Austrian province, Burgenland, with visits to the small town of Rust on the shore of Lake Neusiedl and a guided tour through the Esterhazy Palace in Eisenstadt, the capital of Burgenland. This was followed by a string quartet concert with music by the Austrian composers Joseph Haydn (who had lived and worked in this particular palace for many years) and Wolfgang Amadeus Mozart (whose 250th birthday was celebrated in 2006). The excursion ended with a conference banquet in the state rooms of the palace.Judging from the comments of the participants, HTMC-XII was a big success, and many of the scientists promised to come back to the next meeting, HTMC-XIII. Most probably this will be held in 2009 in California, USA, organized by Prof. Alexandra Navrotsky of the University of California at Davis.Adolf Mikula and Herbert IpserConference Editors

Abstract:

Materials technology is a matter of great applicative and crosscutting interest, as evidenced by their presence in most curriculums of the current industrial engineering degrees. During the development of this matter, it is crucial that the student assimilates not only the relationship among composition, processing and mechanical properties, but also, how all these technological features interact facing the in-service behavior of the material. That is why, within a Doctoral dissertation developed at the Department of Construction and Manufacturing Engineering at the National Distance Education University (UNED), it has designed a computer tool to quantify the stringency level of technological requirements of materials (especially suitable for high demanding applications), characterized by its suitability as interactive teaching material used in the teaching of materials engineering. As a case study, we have chosen a selection of materials for nuclear reactor pressure vessels, because it is a very representative example of the relationship between chemical composition, mechanical properties and in-service behavior.

Abstract:

Features of training specialists, bachelors, and masters in the field of atomic emission spectral analysis at the Department of Physical and Chemical Methods of Analysis [Ural Federal University (UrFU)] are considered. When training bachelors, coverage of the specialty course «Methods of atomic spectral analysis» is reduced almost by half compared to the same course for specialist. Length of practicals and research trainings is also significantly reduced. Therefore, students graduated with a bachelor degree can be incorporated into the actual practical activities of the laboratories at the enterprises and research companies only in laboratory positions. Master’s program is deeper in theoretical knowledge and research training and practicals become of particular importance. Thus, only a full cycle of two-level education can be comparable with the previous engineering training of specialists. The structure of the curriculum and features of setting up advanced training courses (additional professional education) for specialists in analytical laboratories focused in particular on a detailed study of the features of recording atomic emission spectra by the MAÉS analyzer using the ATOM program is presented. The experience of advanced training of the personnel of industrial laboratories conducted at the training centers of UrFU is described. This form of additional professional education is recommended for advanced and refresher’s training of the laboratory personnel at large enterprises.

Abstract:

The POLYCHAR 16: World Forum on Advanced Materials, organized by the University of Lucknow, was held from 17 to 21 February 2008 in the capital of the state of Uttar Pradesh, India. The annual POLYCHAR conferences have been sponsored by IUPAC for several years and are known for combining the broad field of materials sciences with a clear focus on polymeric materials (the name "POLYCHAR" is derived from the term "polymer characterization"). POLYCHAR 16 was supported by many scientific associations and industries such as IUPAC, Abdus Salam International Center for Theoretical Physics (ICTP) (Trieste, Italy), Indian Space Research Organization (ISRO), Department of Biotechnology (DBT) (India), Council of Scientific and Industrial Research (CSIR) (India), Reliance Industries Ltd. (India), Department of Science and Technology (India), Indian Council for Medical Research (ICMR), Indian National Science Academy (INSA), Uttar Pradesh Council of Science and Technology (UPCST) (India), Lucknow Chapter, Materials Research Society of India (MRSI), and University of Lucknow.As in past years, POLYCHAR puts emphasis on the quality of research presented - in contrast to maximizing the number of participants. The areas covered include nanomaterials and smart materials; natural and biodegradable materials and recycling; materials synthesis; polymers for energy; rheology, solutions, and processing; mechanical properties and performance; characterization and structure-property relationships; biomaterials and tissue engineering; dielectric and electrical properties; surfaces, interfaces, and tribology; and predictive methods. Symptomatically, the number of papers on "green" science was higher than at POLYCHAR 15 last year in Búzios, Rio de Janeiro.There were a total of 292 registered participants from 35 countries (Austria, Bangladesh, Belgium, Brazil, China, Colombia, Croatia, Czech Republic, Egypt, Fiji, UK, France, Germany, India, Iran, Israel, Japan, Korea, Kuwait, Mauritius, Malaysia, Mexico, Nepal, Netherlands, New Zealand, Poland, Portugal, Russia, Sri Lanka, Slovakia, South Africa, Ukraine, USA, Uzbekistan, and Venezuela). This reflects the philosophy of POLYCHAR to provide an international forum to encourage young scientists and advanced students to present their scientific work and give them the opportunity to meet with colleagues and well-known scientists to discuss their results, exchange experiences, and make new contacts, in particular, international ones. Many industrial contacts and much international cooperation with exchange of students and scientists have resulted from this and earlier POLYCHAR meetings.This conference volume represents only a small fraction of the multitude of contributions from different parts of materials science - 48 oral contributions and 170 posters. Many of the contributions have review character, some represent excellent original contributions. Only a small number could be selected for this volume because of the limited space that is available. All this was possible with the sponsorship of IUPAC. Highlights of the conference were the Paul J. Flory Research Award (ex aequo) to Prof. Jiasong He, Institute of Chemistry, Chinese Academy of Sciences, Beijing, China; the International Materials Research Award to Dr. Rameshvar Adhikari, Tribhuvan University, Katmandu, Nepal; and numerous awards for young scientists and students, including the IUPAC Poster Award. Special Prof. Brar's 60th Birthday Celebration Awards were given to IUPAC poster prize winners.The next POLYCHAR will be hosted by Jean-Marc Saiter, University of Rouen, Rouen, France in April 2009.Poonam TandonConference Executive Secretary and Co-editor

Abstract:

High rate algal ponds are an important process of biological treatment used either for domestic sewage or food industries effluents and to produce single cell proteins. The results refer to the efficiency of treatment of wastewaters from the tomato concentrate industry and determination of the chemical composition of “Albazod” (microbial biomass) harvested in a pilot system of high rate algal ponds installed in the Department of Environmental Engineering, Faculty of Sciences and Technology, New University of Lisbon, at Monte da Caparica. Depending on the detention time and period of the year, the following removal efficiencies were obtained: COD 68.1 – 94.6%; TOD 57.6 – 85.0%; N-NH4+ 89.4 – 96.2%; colour 29.6 – 91.7% and turbidity 37.2 – 92.7%. Albazod separated from the effluent has a high nutritive value for low detention times (crude protein values of 31.50% and 30.75% dry matter for 4 days and 5 days of detention time, respectively). The highest productivity value was 30.82 g of dry matter/m2/day and was obtained for a detention time of 4 days.

Abstract:

Abstract In most European countries, Hot Mix Asphalt (HMA) technology is still being used as the standard for the production and processing of bituminous mixtures. However, from the perspective of environmental acceptability, global warming and greenhouse gas production, Slovakia is making an effort to put into practice modern technology, which is characterized by lower energy consumption and reducing negative impacts on the environment. Warm mix asphalt technologies (WMA), which have been verified at the Department of Transportation Engineering laboratory, Faculty of Civil Engineering, Slovak University of Technology (FCE, SUT) can provide the required mixture properties and can be used not only for the construction of new roads, but also for their renovation and reconstruction. The paper was created in cooperation with the Technical University of Ostrava, Czech Republic, which also deals with the addition of additives to asphalt mixtures and binders. It describes a comparison of the impact of some organic and chemical additives on the properties of commonly used bitumen binders in accordance with valid standards and technical regulations.

Abstract:

Abstract In the Faculty of Science (University of Hradec Králové) the innovative program in chemistry for the study specialization Physico-technical Measurements and Computer Technology was developed. The innovation of chemistry filed study has been focused especially on increase in competitiveness and in graduates employment. Design of innovation enables graduates applying for the position of experts in physical measurements and informatics and at the same time they expand their competence in the service of the physico-chemical instrumentation in industrial ecology. Because Faculty of Science is not equipped yet in expensive instrumentation for nuclear spectrometry, cross-border cooperation with the Faculty of Natural and Technical Sciences (University of Opole) has been started. In the area of teaching about non-traditional energy sources the cross-border cooperation with the Department of Automation and Renewable Energy Sources, Faculty of Electrical Engineering (Czestochowa University of Technology) has been initiated. Well-developed system of cooperation with companies, which are equipped with the latest technology of environmental protection, was created. In the exchange system Polish students attended for practicing in these companies. The aim of the contribution is to describe one of the means of innovation of chemistry field study in the frame of bachelor study specialization oriented in physics and computer technology. We believe that the new approach will lead to increase in graduate competitiveness as well as to development of their motivation to study and better understanding of regulation principles of chemical processes and patterns.

Full text

Abstract:

An innovative system for stabilizing the organic fraction of municipal solid waste (OFMSW) has been documented on a pilot scale at the Civil Engineering Department of the University of California at Davis. The system involves the combined methods of high-solids anaerobic digestion and aerobic composting for the recovery of energy and the production of compost from the OFMSW. The performance of the high-solids anaerobic reactor was monitored for three mass retention times. The anaerobic digester was operated under extreme as well as normal conditions. The performance of the aerobic compost unit was monitored based on the physical and chemical characteristics of the final humus by-product. In general, the combined process was very stable at a 30 d retention time and is capable of removing essentially all of the biodegradable fraction of the organic fraction of MSW. A biogas production level of up to 6 liters per liter of active volume of reactor was achieved. The process stability and gas production decreased slightly when the retention time was reduced to 15 d. The output from the second stage is a fine humus-like material with a thermal content of about 14.80 MJ/kg.

Abstract:

Natural background levels (NBLs) for targeted chemical elements characterize a specific groundwater body, the knowledge of which represents a fundamental information for environmental agencies responsible for the protection, management, and remediation of territory. The large number of areas subject to strong anthropogenic pressures of a different nature and magnitude makes the job of control authorities particularly difficult. The process to distinguish effective anthropogenic contamination from natural conditions and to define realistic environmental clean-up goals goes through the computation of several mutually dependent statistical methods, some of which have non-trivial resolution and interpretation. In this study, we presented a new tool designed to drive those working in the sector into an articulated path towards NBL assessment. The application software was developed in order to read environmental input data provided by a user-friendly web-based geographic information system (GIS) and to return the NBL estimate of a given chemical element following a wizard that allows for the implementation of two methodologies, i.e., component separation or pre-selection. The project was born from a collaboration between the Department of Environmental Engineering of the University of Calabria and the Department of Environmental Policies of the Calabria Region. The software was used to estimate NBLs in selected chemical species at potentially contaminated industrial sites located in Lamezia Terme, Italy. In the future, the developed calculation program will be the official evaluation tool of the Calabria Region for identifying groundwater thresholds.

Abstract. In January 2020, a scientific borehole planning workshop sponsored by the International Continental Scientific Drilling Program was convened at Cornell University in the northeastern United States. Cornell is planning to drill test wells to evaluate the potential to use geothermal heat from depths in the range of 2700–4500 m and rock temperatures of about 60 to 120 ∘C to heat its campus buildings. Cornell encourages the Earth sciences community to envision how these boreholes can also be used to advance high-priority subsurface research questions. Because nearly all scientific boreholes on the continents are targeted to examine iconic situations, there are large gaps in understanding of the “average” intraplate continental crust. Hence, there is uncommon and widely applicable value to boring and investigating a “boring” location. The workshop focused on designing projects to investigate the coupled thermal–chemical–hydrological–mechanical workings of continental crust. Connecting the practical and scientific goals of the boreholes are a set of currently unanswered questions that have a common root: the complex relationships among pore pressure, stress, and strain in a heterogeneous and discontinuous rock mass across conditions spanning from natural to human perturbations and short to long timescales. The need for data and subsurface characterization vital for decision-making around the prospective Cornell geothermal system provides opportunities for experimentation, measurement, and sampling that might lead to major advances in the understanding of hydrogeology, intraplate seismicity, and fluid/chemical cycling. Subsurface samples could also enable regional geological studies and geobiology research. Following the workshop, the U.S. Department of Energy awarded funds for a first exploratory borehole, whose proposed design and research plan rely extensively on the ICDP workshop recommendations.

Abstract The students frequenting the program Chemical Engineering at the Department of Chemical and Environmental Engineering, Faculty of Chemical and Food Technology of the Slovak University of Technology in Bratislava are taught to be able to combine and develop their knowledge acquired in the area of chemical, energetic, environmental, and safety engineering. Prior to completing their study, they are obliged to develop a report regarding engineering, economic, and safety analysis of important chemical technology. This paper presents the most valuable outputs of the student’s Technology project aimed on simulation and optimization of the fuel additives production technology. 2-Ethoxy-2-methylpropane (ethyl-t-butyl ether, ETBE) production based on liquid-phase etherification of 2-methylpropene with ethanol in the presence of heterogeneous catalyst was studied. Different patented technologies were investigated in terms of their profitability and safeness. The first technology was an isothermal reactor with the product separation via distillation (Kochar & Marcell, 1981). The next ETBE production design assumed was a modification of the previous one; the product separation was carried out using liquid-phase extraction (Pucci et al., 1992). The last design considered in this study was a reactive distillation column with a pre-reactor (Bakshi et al., 1992). In all three technologies, etherification reaction was carried out using Amberlyst ion-exchange resin in its H+ form as the catalyst. Selected ETBE production designs were simulated using Aspen+ program. Their profitability was compared on basis of the investment and operation costs assessment taking into account both the produced ETBE yield and purity. Further, basic safety analysis of all chosen technologies was performed in order to identify possible hazards. Finally, individual and social risk connected with the plant operation was computed. Taking into account these economic and safety criteria, the best alternative for ETBE production was the reactive distillation.

Abstract:

As a physicist, it is a great honor for me to write the preface to this issue of Pure and Applied Chemistry (PAC), which focuses on the synthesis, characterization, and applications of nanostructured advanced materials. Nanoscale science and nanotechnology are rapidly advancing examples of the interdisciplinary nature of science and technology in the 21st century, requiring the mastery of a combination of chemical and physical techniques and a broad vision. In the study of material properties, the nanoscale is truly the interface between the two fundamental natural sciences, where size, geometry, and chemical species all play a significant role in determining the electronic and mechanical properties of nanostructured materials, and their subsequent biological and chemical activity. All these aspects are covered in the selection of papers presented here, written by both established and upcoming chemists, physicists, materials scientists, and technologists.The 13 papers in this issue are selected from the invited presentations at the 3rd IUPAC Workshop on Advanced Materials (WAM III). This event is the third in a series devoted to the general theme of New Directions in Chemistry under the sponsorship of the International Union of Pure and Applied Chemistry (IUPAC). The Workshop was held on 5-8 September 2005 at the University of Stellenbosch in South Africa, and addressed the topic of Nanostructured Advanced Materials. Previous Workshops in this series were held in Hong Kong, 14-18 July 1999, and Bangalore, 13-16 February 2002. It is an indication of the importance of the science of nanomaterials that IUPAC continues to promote the advancement of interdisciplinary research and international collaboration in this area through these flagship workshops. In South Africa, this has been mirrored by the growth of the South African Nanotechnology Initiative (SANi), whose members, particularly at the student level, were lively participants of WAM III, and the recent launch, by the SA Department of Science and Technology, of a National Nanotechnology Strategy with a very strong focus on the characterization and basic properties of nanostructured materials.The atmosphere of the workshop was fully in keeping with the interdisciplinary and international nature of the field, with invited speakers and participants representing a range of disciplines, including inorganic and organic chemistry, physics, materials science, process engineering, and electrical engineering, representing both academia and industry, and 25 countries from all five continents. The formal program consisted of 16 contributed posters, 34 invited talks, and 7 plenary lectures. Although the majority of presentations concerned the synthesis, characterization, and properties of nanoparticles (3 plenary and 8 invited talks), other themes of the workshop focused on nano-electronics (6 invited talks); nanotubes and fibers (1 plenary and 3 invited talks); bottom-up design and self-assembly (1 plenary and 5 invited talks); biorelated and general nanomaterials (5 invited talks); and device application and characterization (2 plenary and 7 invited talks). All of these talks have been made available for download from the University of Stellenbosch website at http://academic.sun.ac.za/unesco/Conferences/Conference2005/programme.htm. The WAM III program also incorporated a German-South African student symposium, with oral presentations from four German students and one South African student, and the annual general meeting of SANi.Acknowledgments are due firstly to IUPAC for their continued support for the WAM series, and to the immediate past president Prof. P. S. Steyn for bringing the workshop to South Africa. In this regard, the support of the international organizing committee, and, in particular, Profs. C. N. R. Rao, P. O'Brien, and J. Wendorff, who gave plenary lectures. Another international organizing committee member, Dr. S. Mathur, organized the student symposium. The local organizing committee, comprising members from various local institutions, was chaired by Prof. R. D. Sanderson of Stellenbosch University, with all the organizational aspects ably handled by Ms. Aneli Fourie.David T. BrittonConference Editor

Abstract:

The aim of this study is to assess the impact of samplers change on the uncertainty associated with the process of the geothermal water sampling. The study was carried out on geothermal water exploited in Podhale region, southern Poland (Małopolska province). To estimate the uncertainty associated with sampling the results of determinations of metasilicic acid (H2SiO3) in normal and duplicate samples collected in two series were used (in each series the samples were collected by qualified sampler). Chemical analyses were performed using ICP-OES method in the certified Hydrogeochemical Laboratory of the Hydrogeology and Engineering Geology Department at the AGH University of Science and Technology in Krakow (Certificate of Polish Centre for Accreditation No. AB 1050). To evaluate the uncertainty arising from sampling the empirical approach was implemented, based on double analysis of normal and duplicate samples taken from the same well in the series of testing. The analyses of the results were done using ROBAN software based on technique of robust statistics analysis of variance (rANOVA). Conducted research proved that in the case of qualified and experienced samplers uncertainty connected with the sampling can be reduced what results in small measurement uncertainty.

Abstract:

Moringa Oleifera is considered to be a natural bio-adsorbent. Unlike chemical coagulants, Moringa Oleifera seeds are environment friendly with various other advantages. The present study investigated the fluoride removal efficiency of Moringa Oleifera from water. Influence of adsorbent dose (1, 2, 4 g/L), contact time (20, 40 and 60 min) and initial fluoride concentration (2 and 5 mg/L) over removal efficiency were determined and optimized. It was found that increased adsorbent dose and contact time enhanced the removal efficiency which is in agreement with the previous studies. The highest removal of 88.1% was achieved when the adsorbent dose and contact time were optimized to 4 g/L and 60 minutes with an initial fluoride concentration of 2 mg/L. The results showed that Moringa Oleifera can be used as an environment friendly, cheap and effective bio-adsorbent for fluoride removal from aqueous solution. All the experimental facilities were provided by Bio-Fuel Lab, Energy & Environment Department, Quaid-e-Awam University of Engineering, Science and Technology, Nawabshah, Pakistan. The samples were analyzed at the Pakistan Council of Research in Water Resources (PCRWR), Tando Jam, Pakistan.

Abstract:

This technical note summarizes a technical comparison of common testing procedures, as well as reviewed of the UN Test N` 5, for the assessment of the self-heating properties of cargoes and materials that has shown a clear trend on maritime fire and explosions events, as well as considering of external factors that can combine self-heating and emit flammable gases to conclude in an unlikely event affecting the security of crews and ships. A high understanding of the external factors effect on the cargo materials certainly will help the application of spontaneous reactions management actions (SRMA) on board of ships during the cargo sea passage. The intended comparison is based on laboratory, industry and field observations and data, whereas the among the external factors considered are, moisture content, stockpile procedure and aging, air velocities and moderate pressures internal and externally to the cargo material. The comparison results have shown that the self-heating and the flammable gas emissions has a common pattern when reacting with any oxygen available source, regardless the reactive material chemical composition. Keywords: reactive materials, self-heating, self-ignition, direct reduced iron fines, materials handling, UN test N` 5, maritime safety, spontaneous reactions, risk management.

Abstract:

This issue of Pure Appl. Chem. is devoted to papers based upon invited lectures delivered at the first IUPAC-sponsored Workshop on Advanced Material, "WAM1: Nanostructured Systems", held at the Hong Kong University for Science and Technology (HKUST) on July 14-18, 1999.The Topic Why nanostructured material? Chemists contribute to the well-being of society by exploiting the properties of the elements of the periodic table, or various forms of combination of elements, to make materials that are useful for "better living through chemistry." What happens if we use all the possible combinations that can be made? There remain great demands for developing new materials to improve our lives in fields such as medicine, energy, improving the environment, communication and transportation. Thus, we have to think of new ways to make materials that can be expected to display properties appropriate to the technologies of the new Millennium! The difference in properties of different elements and their derived compounds is a result of differences in the type of motion that their electrons can execute. This, in turn, depends on the space available for the electronic motion and the degree of its confinement. Thus, the difference between a metal, a semiconductor and an insulator is attributable to the electrons being delocalized in the first, more confined in the second and highly confined in the last. Can we physically cut material size sufficiently to change its electronic degree of confinement and thus its properties? We do know that while copper metal is a conductor, the copper atom and small molecular clusters of copper atoms are insulators. What is the size of an elemental assembly of a metal (i.e. the number of atoms in it) at which the metal-semiconductor or the metal-insulator transition occurs? Of course it depends on the length scale of the property measured. For semiconductors and metals, a large change in properties, e.g. absorption, emission, and conductivity, occurs on the nanometer length scale. Equally important, the property becomes very sensitive to the size of the nanoparticle. It can thus be expected that many variations in these properties should be observed for the same material by simply changing its size. The potential for harnessing these changes of properties in new technological applications is largely responsible for the current appeal of this exciting field. These considerations, along with our personal research interests, convinced me and Professor Joshua Jortner that it would be opportune to adopt this theme for the first IUPAC Workshop on Advanced Material. The publication of the talks given at the Workshop is timely, given the extraordinary rapidity with which new developments are taking place in the field. This collection of papers complements other recent publications of reviews on the topic of nanostructures, since it is more in the nature of a symposium-in-print and offers an assembly of short overviews and research papers which capture the dynamic associated with research at interdisciplinary interfaces, and with the development of attendant synthetic and analytical techniques. The promise of unimagined properties of nanostructured materials and of new-generation applications is an ongoing stimulus for further research, and it is hoped that this publication will contribute to the process, and furnish practitioners with new insights and inspiration. This is truly a multidisciplinary and future-targeted area of scientific research, and one which fully meets the IUPAC vision of 'new directions in chemistry', with its promise of hitherto undefined vistas of opportunity for discovery and exploitation. The WorkshopThe quality of the scientific presentations at this meeting was very high indeed. The strong international representation is in keeping with the spirit of IUPAC as well as the global nature of scientific research. The idea of the meeting was to get scientists active in advanced material from the West to interact strongly with those from the Orient. In this regard, we have succeeded as we achieved representation from seven countries from each side [China (Mainland and Hong Kong), Japan, Korea, Philippines, Singapore, and Taiwan from the Orient, and Canada, France, Germany, Israel, Spain, United Kingdom, and USA from the West]. This great accomplishment of getting us all together in such a delightful atmosphere was the result of the wise sponsorship of IUPAC and the great efforts of many people, whom I would like to acknowledge below.Acknowledgements IUPAC: for its wisdom to sponsor workshops in frontier areas of chemical research. We thank the then-IUPAC President, Prof. Joshua Jortner for cochairing the Workshop. We also thank the IUPAC Secretariat, in particular its Executive Director, Dr. John Jost, for his continuous and prompt support and Dr. Fabienne Meyers for creating and editing our web page for the Workshop and for her essential assistance in the production of this special volume. HKUST: for hosting us. We thank Dr. Nai-Teng Yu of the Chemistry Department, whose willingness to help us by accommodating the Workshop in his Department was essential; Dr. Shihe Yang whose continuous hard work and efforts made it possible to follow up the registration process; the local organizers, in particular, Prof. Leroy Chang and Ping Sheng, who supplied us with the list of participants, the names of some invited speakers and the program of a similar meeting held there recently and the Departmental staff, for their help in getting the arrangements of this workshop finalized. Georgia Tech: Dr. Clemens Burda helped in getting the workshop abstracts and putting the workshop material together, Ms. Michele Papsidero, my own secretary, spent many hours of hard work in following the process, from completing the registration list, to reminding contributors to meet different deadlines including sending the abstracts, and finally in typing and collating the whole program for the Workshop. The assistance of the USA Organizing Committee and in particular, Profs. John Zhang and Rob Whetten at Georgia Tech, was extremely useful in finalizing the scientific program. The speakers: I thank both the plenary and invited speakers who accepted our invitation, most without asking for financial support. Without them, we would not have had such an excellent scientific meeting or this valuable volume of Pure Appl. Chem.I wish to thank Professor James Bull, the editor of this special issue, for his hard work in making sure he received the manuscripts in time, for the review process of these manuscripts and for putting the whole volume together.

Abstract:

The paper outlines achievements obtained in developing a pilot bio-ethanol plant at the Department of Chemical and Mining Engineering (CME), University of Dar es Salaam. The pilot plant consists of: 30 L inoculums tank; 1,700 L fermenter; 1,500 L/day distillation column; and ancillary equipment. The prototype is a platform intended to be used for technology demonstration and research by graduate and undergraduate students studying the production of bio-ethanol using traditional and non-traditional raw materials like coffee mash, cashew fruit, and sisal inulin. The equipment has been developed using locally available engineering resources and the distillation column with 18 sieve tray measures 0.5m diameter 7 m high operates at atmospheric pressure. The condenser is cooled by 15 o C chilled water from utility lines and the reboiler is powered by 63 kW boiler installed at CME. Although the system includes biological, chemical and mechanical engineering details, only the important design issues are presented. A MATLAB code was developed forestimating the number of theoretical plates using the Mc Cabe-Thiele method. The water- ethanol vapour liquid equilibrium VLE data was obtained using relative volatilities estimated by Antoine equations for vapour pressure. The process design was done using various simulation packages and custom programs like Microsoft Excel for mass balance,Microsoft Visio for process and instrumentation (P&I) diagram AutoCAD software for mechanical engineering drawings. After performing hydraulic leak tests, the prototype was tested using blackstrap molasses 80 o brix which was prepared for fermentation using ilution and inoculums formulations developed in Microsoft Excel for water dilution, yeastand nutrients like (NH 4 ) 2 SO 4, KH 2 PO 4, MgCl 2. A batch mash boiling test conducted on the column showed that the response of tray temperatures exhibited first-order delay behavior with an average lag of 17 minutes and a delay of 50 -65 minutes depending on tray distance from the reboiler. Due to lack of feedback control equipment specifically on-linecomposition analyzers and suitable actuators, continuous control of ethanol composition could not be undertaken. It is planned to procure pertinent control hardware during the next phase of the project. However the batch test gave initial ethanol purity of 80% which decreased as the ethanol content in the still was continuously depleted.

E-mail: heliograssi@fca.unesp.br 1 RESUMO O experimento foi conduzido em ambiente protegido, na área experimental do Departamento de Engenharia Rural da Faculdade de Ciências Agronômicas, Universidade Estadual Paulista, Campus de Botucatu, localizado no município de Botucatu, Estado de São Paulo, com latitude sul 22º51’, longitude oeste 48º26’ e altitude de 786 metros. Foram utilizadas mudas do meloeiro híbrido Bônus II. Utilizou-se o sistema de irrigação por gotejamento, “Queen gil”, com vazão de 1,5 litros por hora por gotejador, com 0,30 m de espaçamento entre gotejadores. O manejo da irrigação foi realizado pela reposição integral da evapotranspiração determinada pelo tanque “Classe A”, através de lâminas de irrigação a cada 2 dias. Adotou-se o delineamento inteiramente casualizado no esquema fatorial com duas doses de nitrogênio (60 e 90 kg de N por ha na forma de nitrato de cálcio (120g kg-1 de N) e quatro de potássio (40, 70, 100 e 130 kg de K2O por ha, na forma de cloreto de potássio (600g kg-1 de K2O) em cobertura, via água de irrigação, com 3 repetições, totalizando 24 parcelas. As doses de cada tratamento foram subdivididas em 06 sub-doses, variando em porcentagem de acordo com o desenvolvimento vegetativo da cultura e suas respectivas necessidades de nutrientes: aos 15, 22, 30, 37, 45 e 52 dias do transplantio, respectivamente, com 15, 20, 30, 20, 10 e 5% da dose. Foram avaliados, o diâmetro do caule; o teor de clorofila das folhas; análise química das folhas e nos frutos; as determinações de peso do fruto com e sem casca, comprimento, diâmetro, pH, textura, teor de sólidos solúveis, acidez total titulável e ratio. Os tratamentos nitrogenados não influenciaram nos teores de clorofila das folhas, diâmetro do caule, pesos frescos dos frutos e no formato dos frutos. Doses nitrogenadas e potássicas não alteraram características químicas dos frutos: pH, sólidos solúveis, acidez titulável e ratio. A elevação das doses nitrogenadas e potássicas, respectivamente, reduziram e aumentaram a textura dos frutos; Maiores doses potássicas reduziram os pesos frescos dos frutos e aumentaram o diâmetro do caule do meloeiro. UNITERMOS: fertirrigação, potássio, nitrogênio, melão rendilhado FERNANDES, A. L.; GRASSI FILHO, H. NITROGEN AND POTASSIUM FERTILIZER AND TRICKLE IRRIGATION IN MUSKMELON PLANT(Cucumis melo reticulatus, Naud) 2 ABSTRACT This experiment was held in a plastic green house at the Rural Engineering Department, Agricultural Science College from Paulista State University – UNESP/ Botucatu, São Paulo State, at 22º51’ S latitude, 48º26’ W longitude, and 786m altitude. Hybrid muskmelon seedlings, Bônus II, of 99% purity and 96% germination potential seeds were used. A trickle irrigation system called “Queen gil”, 15-liter flow/hour per trickle, and 0.30 m space between trickles were used. Irrigation was performed by evapotranspiration total replacement determined by a “Class A” pan, using an irrigation schedule every two days. Complete randomized block in a factorial design with 3 repetitions and 24 plots were applied. Two nitrogen doses (60 and 90 kg/N/ha) as calcium nitrate (120g kg-1 N) and four potassium doses (40, 70, 100, and 130 kg/K2O/ha) as potassium chloride (600g Kg-1 K2O) with complementary fertilization by irrigation water have been used. Doses of each treatment were subdivided into 6 sub-doses, with varying percentages depending on plant vegetative development and nutrient requirements at 15, 22, 30, 37, 45, and 52 transplanting days at 15, 20, 30, 20, 10 and 5% dose, respectively. The following parameters were evaluated: stem diameter, chlorophyll content of leaves, and chemical analysis of leaves. Determinations in fruits were carried out as follows: fruit weight with and without peel, length, diameter, pH, texture, soluble solid content, acidity and ratio. The nitrogen treatments did not influence leaf chlorophyll content, stem diameter, fresh fruit weights, and fruit shape. Nitrogen and potassium doses did not alter fruit chemical characteristics: pH, soluble solids, titulable acidity, and ratio. Nitrogen and potassium increasing doses decreased and increased fruit texture respectively. Higher potassium doses reduced fresh fruit weights and increased muskmelon stem diameter. KEYWORDS: muskmelon, nitrogen, potassium, trickle irrigation.

Abstract:

Abstract Synthetic biology aims to redesign and reconstruct living systems for understanding life or for useful real-world applications. In the past two decades, scientists have been able to use engineered living systems to produce many kinds of products from bioplastics to drugs, to construct a minimal bacterium with a fully synthetic genome and to store huge amount of information within a cell. And in 2020, when the COVID-19 pandemic swept across the world, the synthetic biology community became one of the major forces to develop effective diagnostic approaches as well as the drugs and vaccines, to rapidly cope with this great challenge with the state-of-the-art technologies in their hands. In this panel discussion held on 3rd August 2020, eleven pioneering synthetic biologists from six countries across four continents gathered to discuss the development trend, challenges and biosafety issues concerning synthetic biology.

Abstract:

AbstractThe National Science Foundation's National Science Digital Library (NSDL) Program is a premier collective portal of authoritative scientific resources supporting education and research. With funding from NSF, the Materials Digital Library (MatDL) is a collaborative project being developed by the National Institute of Standards and Technology's Materials Science and Engineering Laboratory (NIST/MSEL), the Department of Materials Science and Engineering at the Massachusetts Institute of Technology (MIT), the Department of Chemical Engineering and the Department of Materials Science and Engineering at the University of Michigan (U-M), with Kent State University and University of Colorado at Boulder providing the materials science informatics and workflow technology backbone. As part of the NSDL program, MatDL aims to supports the interface of materials science information and its cognate disciplines, with an emphasis on soft matter. Initial content of MatDL begins with resources selected from NIST/MSEL. Students and faculty in three types of materials science and engineering (MSE) courses at MIT and U-M are taking part in a pilot to use and contribute to MatDL utilizing domain-specific authoring tools. Given the central and interdisciplinary role of materials science in science and engineering, two goals of MatDL are to: 1.) expand its founding partnership with additional participants from the MSE community; and 2.) facilitate the flow of digital materials related knowledge from laboratories where the most recent research discoveries are taking place to the classrooms where new scientists are being trained.

Abstract:

Denis Desty was both a distinguished scientist and preeminently a great creative inventor. He was a man of vision who knew how to turn his visions into reality for he had an outstanding facility for solving real problems. He devised practical techniques for analytical hydrocarbon separations, combustion, gas-flares, the treatment of oil spills, and in a variety of other areas, many of which have had widespread application. There are nearly 500 patents associated with his name. For some he would be the most unforgettable character that they ever met. Denis Henry Desty was born in Southampton in 1923. He came, so he believed, from Huguenot stock and retained throughout his life a certain native Hampshire burr (which would remind some listeners of John Arlott). He was educated at Taunton’s School and later at Southampton University, under Professor N.K. Adam (one of the leading international authorities on surface chemistry). His studies for the honours degree in chemistry were interrupted by volunteer service in the RAF. Here he succeeded in persuading higher authorities to allow him to exchange routine for an opportunity to confuse the enemy with a series of phoney radio signals, and in Ambala he later had some success in teaching others to fly Spitfires. He joined British Petroleum in 1948 (after roaring up to Sunbury on his Ariel Square Four motorbike), and moved through a series of positions first as a Technologist, then Group Leader, Senior Chemist, and finally Senior Research Associate until his retirement through ill health in 1981. His own Special Projects Group was not, however, disbanded for another six years when many past and current members attended a suitable ‘wake’. In 1978 he was appointed Visiting Professor in the Engineering Department of Surrey University, where there is now a Desty laboratory which sets out to introduce undergraduates to some of the innovative combustion technology of the future. Between 1984 and 1986 he was also Visiting Professor in the Chemical Engineering and Chemical Technology Department of Imperial College. He died in January 1994 after a long battle with cancer.

Abstract:

A Review of: Becker, D. A., & Chiware, E. R. T. (2015). Citation analysis of masters' theses and doctoral dissertations: Balancing library collections with students' research information needs. Journal of Academic Librarianship, 41(5), 613-620. http://dx.doi.org/10.1016/j.acalib.2015.06.022  Objective – To determine the citation pattern of graduate students’ theses and dissertations.  Design – Citation analysis.  Setting – An institutional repository at a South African university of technology.  Subjects – 201 Engineering Master’s theses and Doctoral dissertations.  Methods – A random sample of Master’s theses and Doctoral dissertations from the Faculty of Engineering were analyzed. The theses and dissertations were drawn from the institutional repository covering the period 2005-2014. References were checked for format of the cited items including journal, book, conference proceeding, online item (resource with a URL other than a journal, book or proceeding), and other (anything not in the first four categories). The date of all journal articles was recorded. Journal titles were analyzed in terms of country of origin, language, availability in the library, and online access. Data were categorized by department to determine if there were any differences in the use of materials by department. Data were also analyzed by degree level.  Main Results – 101 theses and dissertations were analyzed out of a total of 201 available in the institutional repository. Journals were the most used resource (42%), followed by books (30%), other (12%), online (10%), and proceedings (6%). Doctoral students used a higher percentage of journals than Master’s students. Departmental usage differed. Mechanical (54%) and Chemical (48%) Engineering students mainly used journals. Civil Engineering students mostly used resources from the “other” category (31%). Students in Industrial (41%) and Construction (40%) Engineering mostly cited books. Analysis of the “other” category showed a wide variety of resources used (emails, personal interviews, course notes, conference papers, government publications, national and international standards, manuals and guides, technical reports, and technical notes).  The technology university provides access to 79% of the journal titles used by engineering students in their theses and dissertations. 84% of titles are available online. Students mainly used current articles (i.e., from 2000-present). Students heavily favoured journals from the United States of America and Europe, although South African journals were the fifth most cited by country. English language titles dominated, however Portuguese and French titles were the next most commonly cited. Seventy-four titles were referenced more than 10 times.  Conclusion – The authors state that more electronic resources are being used by graduate students, including “online” information. Journals are the most cited information resource held by the library and the majority of journal titles that were cited can be found in the library. The authors conclude that librarians should work with graduate students to encourage the continued use of library resources. They also state that this information can be useful for identifying journals that could be canceled in times of budgetary cutbacks. The authors note that this study provides the university libraries with insight into the use of library holdings, but being limited to engineering, a more comprehensive study of subjects would provide a broader picture of the collection’s use and provide valuable information for collection development.

Abstract:

Aims: The aim of this study is to determine the effect of applying ethephon on postharvest tomato. Study Design: Completely Randomized Design (CRD). Place and Duration of Study: The study was conducted in the laboratory of the Department of Applied Food Science and Nutrition, Department of Food Processing and Engineering, Department of Applied Chemistry and Chemical Technology of Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh. It was conducted for a period of six months from 1st January, 2018 to 30th June, 2018. Methodology: TSS (Total Soluble Solid) was determined by using hand refractometer, proximate composition by standard AOAC method, vitamin C and β-carotene by UV-spectrophotometric method, sodium and potassium by flame photometric method, titratable acidity, calcium and magnesium by titremetric method. To compare differences in control and treated group, significant difference was considered at the level of P<0.05.  Results: Ethephon treated tomatoes ripen quickly with attractive surface color and had shorter shelf life than non-treated tomatoes (control). Physico-chemical properties including total soluble solid and titratable acidity increased significantly (P<0.05) in treated group (4.66±0.57°B; 0.32±0.01% respectively) than control (3.33±0.57°B; 0.28±0.01% respectively). Moisture content also significantly (P<0.05) increased in ethephon treated tomato (94.15±0.27g/100g) than non-treated (85.54±0.23g/100g). But significantly lower amount of carbohydrate, ash, crude fiber were observed in artificially ripened tomato by ethephon (2.5±0.45g/100g; 0.51±0.02g/100g; 0.82±0.03g/100g respectively) than naturally ripened (3.7±0.26g/100g; 0.59±0.01g/100g; 0.90±0.01g/100g respectively). Apparently protein and fat content were found insignificantly less amount in artificially ripened tomato by ethephon. The significant lowest concentration of vitamin C and β-carotene were observed in ethephon ripened tomato (16.65±0.01mg/100g; 413.33±1.15μg/100g respectively). Mineral contents of ethephon treated tomato (Na 3.65±0.47mg/100g; K 199±1.00mg/100g; Ca 4.75±0.07mg/100g; Mg 8.57±0.19mg/100g) found significantly (P<0.05) fewer amounts than control tomato (Na 3.96±0.01mg/100g; K 213.67±0.57 mg/100g; Ca 5.57±0.15mg/100g; Mg 9.96±0.04mg/100g). Conclusion: Application of ethephon on postharvest tomato hastens ripening time and physico-chemical properties but reduces shelf life and nutritive value of tomato.
