Oil Tanker

Unmanned surface vehicles (USVs) as unmanned intelligent devices can replace humans to perform missions more efficiently and safely in dangerous areas. However, due to the complex navigation environment and special mission requirements, USVs face many challenges in emergency response missions for marine oil spill accidents. To solve these challenges in the emergency response mission of the ‘Sanchi’ oil tanker collision and explosion accident, we designed and deployed an USV to perform the missions of real-time scanning and water sampling in the shipwreck waters. Compared with the previous USVs, our USV owned the following characteristics: Firstly, the improved navigation control algorithms (path following and collision avoidance) can provide high navigation accuracy while ensuring navigation safety; Secondly, an improved launch and recovery system (LARS) enabled the USV to be quickly deployed and recovered in the mission area; Thirdly, a new sampling system was specially designed for the USV. Our USV completed the missions successfully, not only providing a lot of information for rescuers but also offering a scientific basis for follow-up work.

Background: The FDA has been requiring that information about using remdesivir to treat COVID-19 be made available to healthcare providers and patients, including dosing instructions, potential side effects, and drug interactions. It is important to observe the initial indicators of anxiety, fear, and euphoria for families during emergencies, including information on the possible side effects. This situational context is very important in all the world, because it opens doors for providing the use of updated information about treatment follow-up and for offering improved mental health services. Method: The studies were identified in well-known international journals found in two electronic databases: Scopus and Embase. The data were cross-checked with information from the main international newspapers. Results: The high expectations supported by an immediate discourse culminate in frustration and displeasure, while more consistent empirical results are not generated. These two are predictors of psychic suffering, especially due to the scarcity of information and uncertainties. In parallel, recent studies indicate that spreading information without scientific basis intensifies damage to the routine and health of people, which are already impacted by the pandemic situation. This misrepresented spread may be a factor for unleashing fear and, as a consequence, social despair. Conclusions: Based on the impulsive scenarios stimulated in the context of hydroxychloroquine and on the high spread of fake or distorted news, the psychiatric impacts of COVID-19 pandemic associated with the use of remdesivir may be worsened and reflected directly on the population’s self-esteem.

How to ensure a smooth, fast and efficient emergency response procedure becomes a highly concerned issue. However, a procedure of emergency plan may be confusing and inefficient in reality due to delay caused by waiting for decision-making, responding to conflicts and limited resource during the process of dealing with emergency. In this paper, we propose a colored stochastic Petri net to evaluate the security and complexity of emergency response procedure and the reasonableness of resource flow, so as to effectively analyze the potential deficiencies of emergency response procedure. We firstly establish a colored stochastic Petri net, and then convert the colored stochastic Petri net to an isomorphic Markov chain. Studying the structural properties of the colored stochastic Petri net and steady-state nature of the Markov chainprovides a scientific basis for the perfection of emergency plan. Meanwhile, it also ensures an ordered and efficient implementation of emergency response procedure in an emergency.

Abstract The Arctic Contaminants Action Programme (ACAP), originally intended to follow up the work of AMAP (the Arctic Monitoring and Assessment Programme) on identifying the sources of pollution, became an official working group under the Arctic Council in 2006. ACAP has focussed on pollution from Russian sources, the main objective being to accelerate the reduction of national emissions of various environmental pollutants and climate forcers. Basically, ACAP initiates projects with a scientific basis in AMAP assessments of the health of the Arctic. The idea behind the creation of ACAP was to channel the work of the Arctic Council in a more practical direction and to improve the use of the knowledge produced by AMAP. ACAP is one of only two Council working groups not to have been specifically evaluated and analysed by external bodies and academics. This article undertakes a critical analysis of ACAP and argues that there are great potentials for improving its work. ACAP has established a forum where it has been possible to facilitate pilot projects aimed at limiting harmful emissions; this work should be strengthened.

Cereal-based fermented beverages are an opportunity to include probiotics and fiber in human nutrition. Nowadays, increasing the interest for rediscovering the benefits, on scientific basis, of traditional fermented beverages based on cereals. Fermented mashes based on different cereal grist, namely Braga in Romanian, is a healthy and nutritious beverage, a source for new functional products with beneficial effects on human health. Physical-chemical and sensorial characteristics of these beverages depend on the ingredients and method of preparation. In this article was analyzed the influence of the five varieties of wheat on the main physical-chemical and sensorial characteristics of the fermented mashes obtained from grounded debranned millet (Panicum miliaceum), different species of wheat (Triticum aestivum - two variety, Triticum durum - one varieties, Triticum spelta - one variety and Triticum turgidum - one variety) and well modified Pilsner barley malt. There have been two series of determinations: first series with ground millet with the disc mill set to 0.1 mm and a second series with ground millet with the disc mill set to 0.4 mm disc gap. For both series, the other grains used were milled to 0.4 mm disc gap. The mashes content is 1:12 = grounded mix (millet : wheat : barley malt = 1.33:1:1): water. After boiling, reconstruction of the initially content with water, filtering and adding of 7% w/w white crystalline sugar those two series of five sweet mashes was inoculated with a mixed culture (0,01% w/w - dry wheat beer yeast and 0,04% w/w - dry cheese lactic acid bacteria), incubated at 30 ºC for 15 h in the thermostat and then stored at 6ºC for 63 h. At beginning and follow-up of fermentation the mashes were analyzed (pH, volatile and total acidity, total and soluble dry substances, alcohol concentration and dynamic viscosity). At the end of fermentation, it was done the sensory evaluation (colour, sweet, sour, taste, texture and stability). All determinations have made in triplicate and data are shown as mean ± SD. The best results have obtained for mashes containing T. Spelta wheat, followed by mashes with T. durum variety. Highest dynamic viscosity and total acidity was recorded for mashes obtained with Triticum turgidum variety of wheat.

<p>In 2020 as an emergency response to the COVID-19 outbreak, we at EGU pivoted to an online-only conference in a very short period of time. Although this meant that lots of things that we normally enjoy about our General Assembly were lost, some things were also gained, as we were able to experiment with digital solutions to the challenges of digitally presenting science. One of these solutions, the online pre-uploads of display materials and longer-term commenting on them, was very popular, so we are bringing it back again for vEGU21…. with a few adjustments. So how do you upload your displays and comment on materials this year? It’s as easy as 1, 2, 3!</p> <p><strong>1: Add display materials!</strong></p> <p>From 31 March to 31 May, all accepted abstracts will have a space provided to upload display materials. These materials can be whatever you want – a quick slide show, a poster-style image, or a long-form version of your presentation slides – much like you can have in a regular PICO session. You can also, in addition to your data materials, upload a video that can even be a full-length recording of your talk! Your only limit is in the file size: you have 50 MB per abstract for *.pdf, *.ppt/pptx, *.pps/ppsx, *.png, and *.jpg files, and 200 MB for *.mp4 video files.</p> <p><strong>2: Create a vPICO summary slide!</strong></p> <p>During the first part of each vPICO session, each author has a scheduled time slot to give a 2-minute summary of their research. This 2 minute summary will help your audience to decide what ideas they want to follow up with speakers when discussing the work in more detail during the subsequent chat session. To facilitate your live 2-minute presentation, you need to upload a single summary slide as a *.png or *.jpg with a resolution of 150 dpi and 16:9 dimensions (in addition to your longer display materials).</p> <p><strong>3: Commenting is cool!</strong></p> <p>Like last year, commenting will be open on all uploaded display materials between 31 March and 31 May. The main difference for 2021 is that during this time, only registered conference attendees will be able to comment, unless the abstract authors have opted out of the commenting feature (in which case comments will be turned off). Authors will be notified of any new comments by email.</p> <p>We are very excited to see all your wonderful and diverse display materials uploaded before 19 April 2021, though you’ll be able to make adjustments at any time during the two-month commenting period. The 2-minute summary slide has to be uploaded at least 24 hours ahead of your scheduled presentation time, so we are ready to help you present your work for 2021.</p>
