[en] Lean Manufacturing is always important for process improvement in manufacturing industries especially in deem of adoption but the implementation of simple lean is not enough to attain required results. A recent trend has been observed regarding the implementation of strategies like Lean, Agile, Resilient and Green (LARG) in combination to attain fruitful results. However, this combination carries a complication regarding its understanding and implementation and a gap observed regarding the availability of literature study that can cope all these strategies on one platform for understanding and can suggest a proper implementation method. It has been observed that there are some new models that are utilizing electronic configurations to provide powerful platform for process improvements. Utilization of LARG as tool or technique in combination of technologies can be very effective for process improvements. Therefore, this current work emphasis on the combining of LARG along with wireless technologies for obtaining a sustainable improvement in manufacturing sector, which seems unavailable. Based on this ideology, the aim of this research is to conduct a systematic literature study that reviews the previously available LARG research with the objectives to first study the LARG combination for understanding and to develop the interrelation between LARG and previous available technologies for its successful implementation. The literature study results that the LARG combination has many benefits like helpful to attain elimination of non-value activities (lean), responsive to the changing demands of customers as per increasing volatile market (agile), responsive to the unexpected disruptions (resilient) and to adopt environmental protection (green) but typically lacks its utilization with modern technologies (Like RFID) that will be helpful to attain successful implementation. The contribution of this study is the next generation in LARG implementation to emphasis more on the combining of LARG implemetation with utilization of modern technologies. (author)
[en] The carbon-neutral policy implies to produce equal amount of greenhouse gases or less than the environment absorb naturally in the forests, meadows... The carbon-neutral policy is based on 2 tools: the low-carbon national strategy (SNBC) and the long-term plan for energy (PPE). SNBC's purpose is to implement a low-carbon economy in all industrial sectors by 2050. The PPE shows that the demand for electricity is expected to grow significantly in France by 2050 and it warns that the preponderance of any energy in the energy mix can be problematic in case of unavailability for whatever reason, so the PPE advocates for a diversified and balanced energy mix. The aim of such an energy mix by 2050 implies 2 strong actions to be taken: first implementing an efficient strategy for the development of renewable energies and secondly considering the construction of new reactors. The construction of new reactors would be a strong signal for the revitalization of the French industry as a whole, for about 3000 small and mid-sized businesses work in or for the nuclear sector.

[en] Climate change is one of the factors affecting and will continue to affect the attainment of most of the Sustainable Development Goals such as Goal 1, 2, 3, 5, 6, 7, 13 and 14 in developing countries such as Malawi and the Sub-Saharan Africa Region (SSA). Most of the SSA countries depend on agriculture and natural resources depended sectors for economic and social well being. The advent of climate change and its related impacts such as increased frequency of floods, droughts and dry spells present huge challenges for the economies and livelihoods of most SSA countries including Malawi. These climate change impacts on national development have been exacerbated by poverty, energy poverty and lack of different economic livelihood alternatives and options.
[en] Energy sector as a lever for Sustainable Development - Goals: Create competition in generation and commercialization through the creation of the Wholesale Electricity Market. Promote private investment in transmission and distribution through contracts with the Government. Speed up the energy transition towards a low carbon economy: improving the use of clean energies and more energy efficiency. Democratize access to energy.
[en] In 2018 the IPCC noted that nuclear power should be considered among the low-carbon generation technologies that could be used to limit carbon emissions, signaling a change in acceptance of this technology by the climate community. This was echoed when the Clean Energy Ministerial included nuclear energy as part of the ongoing energy future conversation (“NICE Initiative”) in 2018. Combined with the Sustainable Development Goals, global initiatives such as the Sustainable Energy for All partnership and the World Bank’s Energy Sector Management Assistance Program (ESMAP), there is a clear mandate to expand electricity access using clean technologies. Increasingly, nuclear power is being considered in this category. ESMAP’s Tiers of Electricity Supply set targets for household and community electrification. The top tier (Tier 5) threshold sets a minimum household provision of 8.2kWh daily use with availability of 23 hours per day. However, the lowest tier (Tier 1) of access is set at a minimum of 12Wh (which can power, for example, an LED light or phone charger) for 4 hours per day, of which only one of which is specific to after sunset hours. Much of this lower tier access could be provided by a variety of small-scale technology options, including rooftop solar panels. However, as the goal is to move towards reliable, productive, and community uses (the Technical Documentation includes targets for ancillary services such as streetlights) the Tier 5 access also includes grid connection and payment structures. As a result, the technology and management structures will need to evolve alongside technological investments. To facilitate this transition at the rapid pace of expanding access to all persons globally within a decade, innovative solutions are needed.
[en] In the Northeast of Brazil, more specifically, the Sub-São Francisco Valley is a very affected region during periods of drought, where the energy deficit generated by hydroelectric dams is frequent. Thus, this work had the objective of evaluating the role of the wind power source as a complementary energy resource to the conventional hydroelectric source in the region. Through the complementarity indexes, it was estimated the relation between these resources in a certain space and period of time for the case under study. The period analyzed presented significant complementarity indexes, suggesting a considerable energy relation between the resources, verified the potentiality of water-wind complementarity as an alternative that contributes positively to the generation of electric energy for the region.

[en] Recently, two research papers in Scientific Reports, have been published detailing various aspects of radon calibration facility established at Centre for Advanced Research in Environmental Radioactivity (CARER), Mangalore under a DAE-BRNS collaborative project between Radiological Physics and Advisory Division, BARC and CARER. This walk-in-type 222Rn calibration chamber (volume of 22.7 m3), with traceability to international standards, is the largest calibration chamber in the Asia-Pacific region. It adopts an innovative method for the generation of a wide range of 222Rn concentrations (Bq m-3 to kBq m-3) using natural soil gas as a continuous and steady radon source. It has a human-machine interface communication system, a programmable logic controller and sensor feedback circuit for control of environmental and radon parameters and data acquisition. This calibration facility will be useful for harmonising various radon measurement techniques and periodical calibration of several radon detectors being used across India for multiple applications that include - natural background radiation mapping; radon monitoring as earthquake precursor; radon emanometry for Uranium exploration; epidemiological investigations between residential radon and risk of lung cancer in public domain. A brief synopsis of the two published works is presented in this article
[en] We are entering an era in which our planet and our society face major crises. We live simultaneously with three important emergencies: 1) the health crisis, intensified by the Covid-19 pandemic; 2) the biodiversity loss crisis; and 3) the climatic emergency. It should be noted that these crises have profound links between them, and also important differences, but they all have strong social and economic impacts and affect the planet globally. They are the result of an economic model that favors development at any cost and very quick profits even at the expense of sustainability. The Covid-19 crisis posed important questions from the viewpoint of a lack of global governance. In turn, the climate crisis has the potential for very serious socio-economic damage, and its effects are already clearly visible. The loss of biodiversity puts our food security at risk, and the balance of the terrestrial system as well. The Amazon, for example, harbors thousands of viruses in its fauna and flora, and if the unrestrained process of occupation continues, new viruses similar to Sars-CoV-2 will possibly come into contact with our society. Overcoming these three crises requires drastic changes in our economic system, unsustainable in its current format. Continued economic growth on a planet with finite natural resources is not possible. Inequality in developing countries and even between nations is explosive and unfair. We will need a new system of global governance that is able to harmonize measures from different countries, states and municipalities. Sustainability on our planet is possible and necessary. We – the scientific community, society, governments and other stakeholders –will have a lot of work ahead of us in the coming years. We have no alternative but to build a new, more just and sustainable society. (author)
[en] Most of the currently available scenarios for the IPCC 1.5°C and 2°C pathways show a large decrease of energy consumption and an extensive use of intermittent sources with storage capabilities while a few others entail an increase or a stagnation of consumption associated with condensed adaptable energy sources. These considerations are extremely important as they govern the type of strategy to put forward within the two IPCC pathways. Trying to sort out and analyse all the possible human made contributions to energy generation would be beyond the scope of our paper. Therefore, we will address the issues from a more global perspective, using input from the most recent of the numerous studies already done on the subject. First, we have to stick to our goal which is to help politicians, decision makers and other people in charge avoid some of the potential traps associated with various strategies while ensuring that several related Sustainable Development Goals (SDGs) are achieved, at least up to the end of the century and possibly beyond. Our strategy is to first determine envelopes, i.e. to establish limits beyond which the likelihood of not achieving the required SDGs is high. The related SDGs retained in this paper are 1 “No poverty”, 2 “Zero hunger”, 6 “Clean water and sanitation”, 7 “Affordable and clean energy”, 8 “Decent work and economic growth”, 9 “Industrial innovation and infrastructures”, 12 “Responsible consumption and production”, and 13 “Climate action”.
