[en] Current study was designed to investigate and compare the effects of a locally isolated strain of Lactobacillus brevis MF179529 (LB) with commercial probiotic (CP), and yeast (Y) on growth performance and meat quality of chicken. One-day old Cobb broiler chicken (n=270) were randomly allocated into six groups (A-F) having 45 birds in each group. Groups, A-E were continuously given 1g of different probiotics (LB, CP, Y, LB+CP, LB+CP+Y, respectively) in 10 L of drinking water for 42 days except group F (Negative Control) which was given plain drinking water. Feed consumption and weight gain were recorded on weekly basis. Subsequently, at day 42, birds were slaughtered and breast meat samples were processed for meat quality parameters. FCR of groups A, D and E was significantly lower than group F. Similarly, group A displayed high body weight compared to B, C and F groups (p<0.05). Among color attributes, L* (groups A-E) and b* (Group A, C-E) were significantly higher than group F, while a* of group A was higher (p<0.05) than groups C and F. The results indicate that supplementation of LB alone and in combination with, commercial probiotics lead to significant improvement (p<0.05) in growth rate, total proteins, mineral and fat contents as well as color attributes and tenderness of meat.

[en] As nuclear technology plays a significant role in energy generation, efforts to ensure the long-term sustainability of nuclear safety are crucial. Recently, young people in many countries have been turning away from careers in nuclear. With nuclear safety relying on a robust transfer of knowledge to new generations, how can the international nuclear community attract young people to careers in nuclear in general and nuclear safety in particular? Across the world, young people have driven the protests for action against climate change, the biggest global challenge faced today. These young people are educated about climate-related issues and are eager to participate in the global discussion about the future of the planet. Climate change mitigation remains a key driver for maintaining and expanding the use of nuclear power, and the latest IAEA annual projections show that global nuclear electrical capacity could double by 2050. This is an opportunity for the nuclear industry and the international community to present nuclear and nuclear safety as an exciting and relevant career choice in a growing and innovative field. With a comprehensive education in nuclear, an understanding of its benefits for people and the environment, career progression opportunities and the comprehensive diversification of its workforce, nuclear can become a coveted career.
[en] Since the outbreak of the Covid-19 health crisis, Orano has implemented a set of measures to ensure both the health of its employees and the continuity of its customers' businesses, in compliance with the directives of national and international health authorities. At the reporting date of the financial statements, the only significant disruptions related to Covid-19 concern the group's mining activities. The Cigar Lake mine operated by Cameco and the McClean Lake mineral processing plant in Canada, which were stopped for the first time at the end of March with a resumption of production in September, were again phased out at the end of December in view of the development of the local health situation. No contract termination with customers or suppliers was noted due to the pandemic. One-off agreements have been negotiated with certain customers in order to reorganize deliveries beyond 2020 without prejudice to the parties. While the Covid-19 crisis does not affect the value of the group's industrial assets, it has severely disrupted activities, particularly in the Mining and Back End sectors. Despite these uncertainties and thanks in particular to the measures implemented, the group achieved an EBITDA rate of 25.3%, an improvement of +1.5 point compared to 2019. Activity preserved and operational performance improved despite Covid: - Order intake of Euros 1.9 billion and no impact of the crisis on the backlog; - Revenue down by -2.5% (bps) compared to 2019 due to production stoppages and postponements of activities, in connection with the pandemic; - EBITDA of Euros 931 million compared to Euros 900 million in 2019 (rate up to 25.3% compared to 23.8% in 2019). Positive net cash flow and improved liquidity: - Net cash flow of +Euros 144 million (compared to +Euros 219 million in 2019) and maintenance of a coverage rate of 100% of end-of-life cycle liabilities; - Net debt down to Euros 2.15 billion. Net income attributable to owners of the parent impacted by the health crisis: - Adjusted net income attributable to owners of the parent improved at -Euros 91 million (compared with -Euros 145 million in 2019) but impacted by the Covid and an additional end-of-life cycle provision; - Net income attributable to owners of the parent down to -Euros 70 million (compared to +Euros 408 million in 2019) reflecting the same effects and a lower performance of the financial markets in 2020. Financial outlook for 2021: - A recovery in revenue growth; - Consolidation of EBITDA rate between 23% and 26%; - Continuing positive net cash flow.
[en] With the Covid-19 crisis and its health, social and economic consequences, 2020 has demonstrated the urgent need to act to support the development of more just, united and sustainable societies. Unfortunately, the long-awaited leap has yet to come. As the world will need to decrease fossil fuel production by roughly 6% per year between 2020 and 2030 to follow a 1.5 deg. C consistent pathway, it is crucial that financial players put an end to their support to fossil fuel companies. They should both stop any support to coal and act with zero tolerance towards the companies expanding the most climate-damaging sectors, such as shale oil and gas. One year ago, on January 14, Larry Fink announced BlackRock was finally on its way to investing sustainably. The largest investor in the world, with $7.8 tn in assets under management, also published a coal policy, aiming at 'exiting thermal coal producers' but only excluding mining companies with more than 25% of revenues from coal production. To this day, BlackRock still has no policy regarding its investments in other fossil fuels. Reclaim Finance has conducted research on BlackRock's holdings (as of October 2020) to verify the real-world consequences of these announcements and assess the investor's exposure to the coal sector. Unfortunately, results show that even with this new policy, BlackRock remains a massive investor in coal companies and even in companies planning new coal projects, despite research showing that such projects are incompatible with any serious climate commitment. BlackRock has a major problem with its passively managed investments, which make it widely exposed to coal assets likely to become stranded. They also massively expose it to other fossil fuels, as even the most polluting companies are not excluded from BlackRock's investments. BlackRock's half-hearted steps in 2020 to invest more sustainably have proven to be superficial. Our analysis shows that the action taken is utterly insufficient to truly curb investments in the sector most problematic when it comes to climate change: fossil fuels. 2021 is a critical year for climate action, with new commitments to reduce greenhouse gas emissions expected by private and state actors ahead of COP 26 in Glasgow. As a first step towards the necessary phase-out of fossil fuels investments, BlackRock must immediately step up the ambition of its global coal exclusion policy, by extending its scope to the entire coal value chain and to all its assets.
[fr]Avec la crise du covid-19 et ses consequences sanitaires, sociales et economiques, 2020 a demontre l'urgence d'agir pour soutenir le developpement de societes plus justes et plus durables. Malheureusement, le sursaut tant attendu n'est pas la. Nous savons desormais qu'une baisse annuelle de 6% de la production mondiale d'energies fossiles est necessaire entre 2020 et 2030 pour rester sur une trajectoire 1,5 deg. C. Il est donc crucial que les acteurs financiers mettent fin a leur soutien aux entreprises des energies fossiles. Ils doivent a la fois cesser tout soutien au charbon et acter une tolerance zero envers les entreprises qui developpent les secteurs les plus nefastes pour le climat, tels que le petrole et le gaz de schiste. Larry Fink annoncait il y a un an, le 14 janvier 2020, que BlackRock allait se transformer pour investir plus durablement. Le plus gros investisseur au monde, avec 7 800 milliards de dollars d'actifs sous gestion, publiait egalement une politique charbon, visant a 'desinvestir des producteurs de charbon thermique' mais n'excluant que les societes minieres tirant plus de 25% de leurs revenus de la production de charbon. A ce jour, BlackRock n'a toujours pas de politique concernant ses investissements dans les autres energies fossiles. Reclaim Finance a passe au crible les investissements de BlackRock (a octobre 2020) pour verifier les consequences reelles de ces annonces et evaluer l'exposition de l'investisseur au secteur du charbon. Malheureusement, les resultats montrent que malgre sa nouvelle politique, BlackRock reste un investisseur massif dans les entreprises du secteur du charbon. Ses investissements dans les entreprises qui continuent de developper de nouveaux projets lies au charbon sont egalement eleves, alors que ces projets sont incompatibles avec tout engagement serieux en faveur du climat. BlackRock a un gros probleme avec sa gestion passive, qui l'expose fortement a des actifs charbon susceptibles de devenir bloques - des 'stranded assets'. Ses fonds geres passivement l'exposent aussi massivement a d'autres energies fossiles, les entreprises les plus polluantes de ces secteurs n'etant pas exclues des investissements de BlackRock. Les mesures timides prises par BlackRock en 2020 pour investir plus durablement se sont revelees superficielles. Ces mesures sont insuffisantes pour freiner de facon efficace les investissements dans le secteur le plus problematique en matiere de changement climatique: les energies fossiles. 2021 est une annee cruciale pour l'action climatique, avec de nouveaux engagements de reduction des emissions de GES d'acteurs prives et publics attendus pour la COP 26 a Glasgow. Comme premiere etape vers la fin necessaire des investissements dans les energies fossiles, BlackRock doit immediatement renforcer l'ambition de sa politique globale d'exclusion du charbon, en etendant son champ d'application a l'ensemble du secteur du charbon et a tous ses actifs sous gestion.
[en] The fishing industry of the China is the largest in world which is usually believed to be facing overexploitation risk. In this condition, it becomes necessary to estimate stock status of fishery resources particularly having commercial importance. Thus, this study is the first time attempt to know whether Spanish mackerel, a major landed fishery resource in Shandong, China, is experiencing overexploitation or not by estimating its stock status. For this purpose, long data series, 2006-2016, comprised of catch and effort figures was statistically analyzed to know maximum sustainable yield (MSY) of this resource and its ongoing regime. In total, three surplus production models (SPMs) were used in this study, viz., Fox (FM), Schaefer (SM) and Pella-Tomlinson (PTM) with the help of two famous fishery statistical routines, viz., catch and effort data analysis (CEDA) and a stock production model incorporating covariates (ASPIC). For initial proportion (IP) 1, CEDA estimated MSY in a range between 41000-50000 t, whereas, ASPIC calculations remained between 44000-52000 t. Furthermore, results also showed that fishing mortality (F) is increasing while biomass (B) is swiftly decreasing. Based on the results it can be concluded that Spanish mackerel is facing the risk of overexploitation. Thus, it is recommended to make such policies which can conserve this fishery resource for future. (author)
[en] While nuclear and radiological accidents are few and far between, in-depth analyses show that weaknesses in safety culture are root causes in most cases. Since the Fukushima Daiichi nuclear accident in 2011, the safety culture concept that puts layers of safety first has been and is being implemented rapidly. To better understand how attitudes are shifting towards strengthening safety in the nuclear industry, we spoke to Tom Mitchell, Chairman of the World Association of Nuclear Operators (WANO). At the helm of WANO for two years, and with over 40 years of experience in the nuclear industry, Mitchell is leading the nuclear operator community’s focus towards a strengthened safety culture. WANO is a non-profit organization that helps its global membership of commercial nuclear power plant operators achieve operational safety and reliability by providing peer reviews, and access to technical support and a global library of operating experience.
[en] Why is leadership vital in nuclear safety? Leadership is needed to initiate appropriate safety actions, motivate staff to ensure safety procedures are followed 24/7, and provide guidance on implementing safety measures. Learning about the importance of leaders in safety is part of the IAEA International School of Nuclear and Radiological Leadership for Safety, launched in 2016. Cultivating a safety culture among staff, so that they can understand the importance of safety and the measures required to sustain it, is key in the nuclear industry. Establishing a strong safety culture is one the most fundamental management principles when using nuclear technology. It aims to strengthen the implementation of a systemic approach to safety, that is, the interaction between humans, technology and organizations within the national nuclear infrastructure. The importance of safety culture is one of the key lessons learned from the Fukushima Daiichi nuclear accident.
