The High Court of Bangladesh has halted the breaking of the floating oil production and storage tanker, North Sea Producer, following discovery of radioactive substances aboard the vessel. The radioactive substances accumulated over the years of processing crude oil were found in inside pipes, with radioactive level above permissible, Danish TV2 reported. “Following a petition filed by our member Bangladesh Environmental Lawyers Association (BELA), the courts have maintained the halt in breaking the ship,” NGO Shipbreaking Platform confirmed to World Maritime News. As explained, a division bench of the Bangladesh High Court has directed the Bangladesh Atomic Energy Commission (BAEC), the Bangladesh Atomic Energy Regulatory Authority (BAERA), and the Marine Port Initiative (MPI) of the Customs to produce their reports on radioactive contamination of the FPSO before the court within 10 weeks. At the same time, UK environmental authorities DEFRA are said to be investigating the circumstances surrounding the export of the hazardous waste laden North Sea Producer from the Tees river in the UK to Bangladesh. North Sea Producer, previously owned by Maersk, left the UK in May 2016 and was towed to Bangladesh, where it arrived on 14 August 2016, only to be beached two days later at the Janata Steel shipbreaking yard in Chittagong. The NGO Shipbreaking Platform said back in October 2016 that the vessel likely contained large amounts of highly contaminated residues including natural occurring radioactive material (NORM). Bangladeshi shipbreaking yards are not equipped with any infrastructure that could safely remove and dispose of such toxic wastes. As disclosed by Maersk at the time, the ship was sold for further operational use, without revealing the identity of the buyer. “The Producer was sold by Maersk to cash buyers GMS. It is obvious that Maersk knew that the ship would end up being scrapped on a South Asian beach putting both workers and the environment at risk. We have called upon the UK to hold both Maersk and GMS accountable for the illegal export of this toxic laden ship. The case is very indicative of the dodgy practice of selling ships for scrap via middle men known as cash buyers,” Ingvild Jenssen, Director of the NGO Shipbreaking said. According to the platform, the North Sea Producer was allowed into Bangladesh based on a fake certificate stating that the tanker did not contain any hazardous materials. “A false declaration dated 3 August, 2016 was submitted to the Bangladesh authorities by the St Kitts and Nevis based post box company called Conquistador Shipping Corporation set up by cash buyers Global Marketing Systems (GMS). The Bangladesh Department of Environment however never issued environmental clearance in favor of breaking of the vessel,” the platform added. The vessel was owned and operated by UK-based North Sea Production Company, a joint venture between Danish Maersk and Brazilian oil & gas company Odebrecht, with 50% ownership each, and operated in the North Sea as an FPSO. Maersk is yet to reply to World Maritime News on the matter.

The first CERN South Asian High Energy Physics Instrumentation workshop demonstrated the vibrancy of research in the region and the opportunities for closer international collaboration. Le premier atelier CERN-Asie du Sud sur l’instrumentation pour la physique des particules, qui s’est déroulé en juin au Népal, a montré le dynamisme de la recherche dans la région et révélé des perspectives pour une collaboration internationale plus étroite avec le CERN et d’autres organisations. Particle physics is evolving as a result of greater co-ordination and collaboration on a global scale. This goes hand in hand with CERN’s policy of increased networking with organisations and institutions worldwide. In 2010, the CERN Council approved a radical shift in CERN’s membership policy that opened full membership to non-European states, irrespective of their geographical location. At the same time, the Council introduced the status of associate membership to facilitate the accession of new members, including emerging countries outside of Europe, which might not command sufficient resources to sustain full membership (CERN Courier December 2014 p58). Interest in membership and associate membership of CERN continues to grow (CERN Courier January/February 2017 p5). CERN’s geographical enlargement policy offers clear opportunities to reinforce the long-term aspirations of the high-energy physics community. Enlargement is not an aim in itself. Rather, the focus is on strengthening relations with countries that can bring scientific and technological expertise to CERN and, in return, allow countries with developing particle-physics communities to build capacity. Presently, CERN has 22 Member States, seven associate Member States, and six states and organisations with observer status. From the South Asia region, Pakistan and India have recently become associate members. International Co-operation Agreements (ICAs) have been signed with Bangladesh, Nepal and Sri Lanka. The first CERN South Asian High Energy Physics Instrumentation (SAHEPI) workshop on detector technology and applications, held on 20–21 June at Nepal’s Kathmandu University, Dhulikhel, brought together physicists and policy makers from the South Asia region and Mauritius. Representatives from Afghanistan, Bangladesh, Bhutan, India, the Maldives, Mauritius, Nepal, Pakistan and Sri Lanka were invited to attend. At least one senior scientist and one student from each country participated, making a total of about 70 participants, more than half of whom were students (representatives from the Maldives and Bhutan were not able to attend due to other commitments). The aim of the workshop was to bring together representatives from CERN and South Asia countries to strengthen the scientific co-operation between the Organization and the South Asia region. The workshop also provided the opportunity for countries to establish new contacts within the region, with the objective of initiating new intra-regional co-operation in high-energy physics and related technologies. The workshop was initiated as part of CERN’s broader efforts to establish relations with regions, complementing relations with individual countries, and follows similar regional approaches in Latin America and South-east Asia. Progress in particle physics relies on close collaboration between physicists, technicians, hardware and software engineers and industry, and both Member States and associate Member States enjoy opportunities to apply for staff and fellowship positions and bid for CERN contracts. Collaborating with CERN also trains young scientists and engineers in cutting-edge projects, giving them expertise that can be brought to their home nations, and offers great opportunities for educating the next generation through CERN’s teacher programmes and others. Participation in CERN programmes has already fostered successful scientific collaborations in South Asia, where researchers have participated in many of CERN’s pioneering activities and made a significant contribution to the construction of the LHC. Indeed, CERN’s relations with South Asia feature strong partnerships dating back decades, particularly with India and Pakistan. In 1994, CERN and the government of Pakistan signed an ICA concerning the development of scientific and technical co-operation in CERN’s research. This agreement was followed by the signing of  several protocols, and today Pakistan contributes to the ALICE and CMS experiments as well as to accelerator projects such as CLIC/CTF3 and Linac 4, making Pakistan a significant partner for CERN. Pakistan has also built various mechanical components for ATLAS and for the LHC, and made an important contribution to the LHC consolidation programme in 2013–2014. In July 2015 Pakistan  became an associate Member State of CERN. Given its long tradition and broad spectrum of co-operation with CERN since the 1970s, combined with the country’s substantial scientific and technological potential, India applied for associate membership in 2015. In particular, in 1996 the Indian Atomic Energy Commission (AEC) agreed to take part in the construction of the LHC, and to contribute to the CMS and ALICE experiments and to the LHC Computing Grid with Tier-2 centres in Mumbai and Kolkata. In recognition of its contribution to the construction of the LHC, India was awarded observer status in 2002. The success of the partnership between CERN and the Indian Department of Atomic Energy (DAE) regarding the LHC has also led to co-operation on novel accelerator technologies through DAE’s participation in CERN’s Linac 4, Superconducting Proton Linac (SPL) and CTF3 projects, and CERN’s contribution to DAE’s programmes. India is also participating in the COMPASS, ISOLDE and n_TOF experiments. India became an associate Member State in January 2017. In the recent past, contacts have also been established with several other countries in the South Asia region. Collaboration between Sri Lanka and CERN has been ongoing for a number of years, following an expression of interest signed between the CMS collaboration and the University of Ruhuna in 2006. This saw the first CERN summer students from Sri Lanka and the first PhD student graduating in 2013. The conclusion of the ICA with the government of Sri Lanka in 2017, and the expected entry of a consortium of universities from Sri Lanka into the CMS collaboration, are important steps for growing the country’s national high-energy physics capacity. Sri Lanka is moving towards membership of the CMS collaboration with an interest in contributing to the experiment’s upgrade programme, driven initially by the University of Colombo and the University of Ruhuna. Official contacts between CERN and Bangladesh were established in 2012 with the signing of an expression of interest. This provided an interim framework to enable scientists, engineers and students from universities and research institutes of Bangladesh to further develop their professional training, in particular through participation in CERN’s scientific and training programmes. In 2014 CERN and Bangladesh signed an ICA, and the first Bangladesh–CERN school on particle physics was held at the University of Dhaka that year. Bangladesh is currently participating in the ALICE experiment as an associate member and working on physics analysis. There is a high potential for future development of the collaboration with CERN, through 39 public universities and 93 recognised universities and the high number of multidisciplinary research facilities of the Bangladesh Atomic Energy Commission. Nepal has seven universities: Tribhuvan University (the largest and, until around 1990, the only university in the country); Kathmandu University; Pokhara University; Purbanchal University; Mahendra Sanskrit University; Far-western University; and the Agriculture and Forestry University. Tribhuvan and Kathmandu universities are considered to be best placed to develop scientific and technical co-operation with CERN, and collaborative activities are already under way between CERN and Nepal. Students from Nepal have been participating in the CERN summer-student programme for non-Member State nationals, and teachers from Nepal have taken part in the CERN high-school teachers programme. Several workshops on particle physics and related areas have been held at Tribhuven University and Kathmandu University, and an ICA between Nepal and CERN has recently been concluded. Contacts with the physics communities of Afghanistan, Bhutan, the Maldives and Mauritius were established through the June workshop and will be pursued to explore ways and means to develop capacity in physics and related areas in these countries. The department of physics at the University of Kabul was established in 1942 and includes programmes for undergraduate and graduate studies in physics as well as student laboratories. The department of physics at the University of Mauritius includes research programmes in radioastronomy and applied radio frequency and it also operates the Mauritius Radio Telescope, while its undergraduate teaching programme includes courses in nuclear and elementary particle physics. The nature of the national programmes in high-energy physics and related areas in these South Asian countries was the focus of discussions at the Kathmandu workshop. The aim was to identify synergies to establish stronger scientific collaboration across the region, such as promoting the exchange of researchers and students within the region. These efforts will help to build capacity, particularly in the countries with emerging high-energy physics programmes that face challenges in research infrastructure and university curricula. The motivation and enthusiasm of the participants was palpable, and it was clear to see the efforts they put in for research and education. The proceedings of the workshop together with the identified strengths, weaknesses, opportunities and threats of the national programmes in high-energy physics and possibilities to strengthen the intra-regional co-operation will be presented to representatives of the governments from the participating countries with the objective to raise awareness at the highest political level. CERN will continue to engage with the region in an effort to build capacity in high-energy physics research and education and to facilitate collaboration with CERN. It was decided that due to the success of this workshop, discussions will continue in Sri Lanka in 2019.

This study examines the use of intact samples as an alternative to powder in conventional batch sorption studies to determine the distribution coefficient (Kd). Stable cesium (133Cs) and strontium (87Sr) were used under specified geochemical conditions to compare the Kd values of powder and block pumice tuff samples. The aim of the study was to infer any Kd difference under laboratory and field conditions. Kd values for block samples were found to be less than one order of magnitude lower than powder materials for both Cs and Sr on fresh tuff, and more than one order of magnitude lower in oxidized tuff. Destruction of micropores in oxidized tuff was estimated to be mainly responsible for reducing Kd values in oxidized tuff. However, approximately one order of magnitude difference in Kd values indicates that homogenously prepared intact samples can be used for sorption coefficient measurement at closer to in situ conditions. Pore size distribution analysis using mercury intrusion porosimetry revealed that lower Kd values on block samples result from lower surface area available as sorption sites due to inaccessible closed pores in the intact solid. © 2017 Science Press, Institute of Geochemistry, CAS and Springer-Verlag Berlin Heidelberg

This paper presents an evaluation of future energy-supply strategies for the United Arab Emirates (UAE) power sector. This paper also identifies the prospects for the further economic development of the country while addressing energy security issues and mitigating environmental impacts. It explores technology choices to meet the future demand in the most cost efficient way based on existing and innovated technologies. The analyses are done for UAE energy system applying MARKAL model. Different policies such as a CO2 emission reduction constraint, renewable energy production targets, and subsidy minimization through international benchmarking for domestic gas prices are applied for this analysis. The results show that the alternative policy scenarios directly allocate clean advanced and renewable technologies to generate electricity. The alternative policy scenarios reduce CO2 emissions in power sector. The simulation results from model show that alternative sustainable energy development policies expected total system cost is not significantly higher. The cumulative system cost increases, relative to the base scenario by 9% and 11% for CO2 emission reduction and renewable target production scenarios, respectively. Use of primary resources to meet the demand is reduced and the supply of primary energy resources is diversified. © 2013 Elsevier Ltd.

In this study, composite scaffolds were prepared with polyethylene oxide (PEO)-linked gelatin and tricalcium phosphate (TCP). Chitosan, a positively charged polysaccharide, was introduced into the scaffolds to improve the properties of the artificial bone matrix. The chemical and thermal properties of composite scaffolds were investigated by Fourier transform infrared spectroscopy, thermogravimetric analyzer, differential thermal analyzer. In vitro cytotoxicity of the composite scaffold was also evaluated and the sample showed no cytotoxic effect. The morphology was studied by SEM and light microscopy. It was observed that the prepared scaffold had an open interconnected porous structure with pore size of 230-354 μm, which is suitable for osteoblast cell proliferation. The mechanical properties were assessed and it was found that the composite had compressive modulus of 1200 MPa with a strength of 5.2 MPa and bending modulus of 250 MPa having strength of 12.3 MPa. The porosity and apparent density were calculated and it was found that the incorporation of TCP can reduce the porosity and water absorption. It was revealed from the study that the composite had a 3D porous microstructure and TCP particles were dispersed evenly among the crosslinked gelatin/chitosan scaffold. © 2012 Wiley Periodicals, Inc.

Renewable and Sustainable Energy Reviews | Year: 2014

Energy is an important input for national socio-economic development. The current trends of energy supply and demand are not sustainable because of the expected huge gap between demand and supply in the future. The fossil fuels resources are limited and use of these fuels has a negative impact in the environment. Holding energy at a secure level and global climate at a safe level require integration of renewable energy technologies (RETs) in the energy supply-mix. Development of RETs in a country depends on its renewable energy readiness (RE-Readiness) that indicates the gaps and strengths of their development. In light of the various initiatives proposed to turn North Africa into a renewable energy producer and extend its electricity supply to its neighboring European counties, it demands to assess the RE-Readiness. The main object of this paper is to develop and disseminate an assessment framework to find North African countries RE-Readiness for deployment of RETs. This framework is adopted in which the paper applies a consistent methodology across all the North African countries× © 2014 Elsevier Ltd. All rights reserved.

Silk is a strong natural proteinous fiber and E-glass is a very strong synthetic fiber. Compression molding method was used to fabricate B. mori silk fiber reinforced polypropylene (PP) matrix composites. The tensile strength (TS), tensile modulus (TM), bending strength (BS), bending modulus (BM) and impact strength (IS) of prepared composites were 55.1MPa, 780MPa, 56.3MPa, 3450MPa and 17kJ/m2, respectively. Synthetic E-glass fiber reinforced PP based composites were fabricated in the same way and TS, TM, BS, BM, IS of E-glass fiber reinforced polypropylene composites were found to be 128.7MPa, 4350MPa, 141.6MPa, 6300MPa and 19kJ/m2, respectively. Gamma radiation is high energy ionizing radiation and was applied to increase the mechanical properties of the composites. Application of gamma ray increases the mechanical properties of silk/PP composites to a greater extent than that of E-glass/PP composites. © 2011 Elsevier Ltd.

This paper examines the impacts of CO 2 emission reduction targets and carbon tax on future technologies selection especially solar PV and energy use in Bangladesh power sector during 2005-2035. It also examines the co-benefits of energy security of the country. The analyses are based on a long-term energy system optimization model of Bangladesh using the MARKAL framework. The results of the study show that on a simple cost base, power generated from solar PV is not yet competitive with that of fossil fuel-based power plants. Alternative policies on CO 2 emission constraints reduce the burden of imported fuel, improve energy security and reduce environmental impacts. The results show that the introduction of the CO 2 emission reduction targets and carbon tax directly affect the shift of technologies from high carbon content fossil-based to low carbon content fossil-based and clean solar PV technologies compared to the base scenario. The cumulative net energy imports during 2005-2035 would be reduced in the range of 33-61% compared to the base scenario. The total primary energy requirement would be reduced in the range of 4.5-22.37% and the primary energy supply system would be diversified. Solar PV plays an important role in achieving reasonable energy security. © 2012 Elsevier Ltd.

About 48 % cotton fiber is consumed as clothing materials all over the globe. It is popular for softness, versatility, absorbance and breathability. Cotton is hydrophilic in nature and therefore, it can absorb sweat from the human body and can release in the surface that makes it comfortable. But it has some inherent limitations such as wrinkle, shrinkage, low dye uptake and microbial degradation. Various approaches have been made to overcome the above limitations. Surface modification of textiles to impart antimicrobial activity, shrinkage, wrinkle resistance, decreased skin irritation, increase dye exhaustion and even enhancing fragrance is the most recent trends in textile chemistry. Various monomers, polymers and biopolymers are applied in different ways to improve different properties of cotton. Chitosan is the mostly used biopolymer in this regard for its biocompatibility, biodegradability, nontoxicity and antimicrobial activity. This paper is a short overview of the most recent development in surface modification of cotton using biopolymers such as chitosan, starch and its derivatives and some other synthetic monomers and polymers. © 2012 Springer Science+Business Media, LLC.

Concentrations of eight heavy metals (Pb, Cd, Ni, Cr, Cu, Zn, Mn, and As) in the muscles of ten species of fish collected from Bangshi River at Savar in Bangladesh were measured in two different seasons. The concentrations of the studied heavy metals, except Pb in Corica soborna, were found to be below the safe limits suggested by various authorities and thus gave no indication of pollution. The present study also showed that, Zn was the most and Cd was the least accumulated metal in the studied fish muscles. ANOVA analysis clearly revealed that there was a significant variation (CI = 95%) of the heavy metal concentrations in different fish species in the Bangshi River. Significant positive correlations between the heavy metal concentrations in fish muscles were also observed in both seasons. From the human health point of view, this study showed that there was no possible health risk to consumers due to intake of studied fishes under the current consumption rate. © 2012 Elsevier Ltd.
