Способ бескоксовой переработки ванадийсодержащего рудного сырья с получением легированной ванадием стали, горячих металлизованных окатышей и ванадиевого шлака

Изобретение относится к области металлургии, в частности к процессам металлизации и электросталеплавильному производству. В шахтной печи осуществляют металлизацию ванадийсодержащего рудного сырья с использованием в качестве восстановителя горячих восстановительных газов, поступающих из газификатора с жидкой ванной, где с одновременным получением газа производятся ванадийсодержащий полупродукт и ванадийсодержащий шлак. Металлизованное сырье, ванадийсодержащий полупродукт, металлургический скрап подают в дуговую электропечь для выплавки стали. Перед подачей в электропечь ванадийсодержащий полупродукт поступает в агрегат деванадации для окисления ванадия с получением рафинированного полупродукта и ванадийсодержащего шлака. После чего рафинированный полупродукт, металлизованное сырье и металлургический скрап подают в электропечь. В электропечи вначале проплавляют рафинированный полупродукт и металлургический скрап, сливают шлак и на полученный расплав подают и проплавляют металлизованное сырье до получения стали. Ванадийсодержащий шлак, полученный при деванадации ванадийсодержащего полупродукта, а также не использованное для выплавки стали металлизованное сырье, полученное в шахтной печи, используют как товарную продукцию. Преимуществом предлагаемого изобретения является удешевление процесса получения легированной ванадием стали, снижение энергоемкости процесса и увеличение степени извлечения ванадия на всех стадиях технологической цепочки

Promoting sustainability through connection

On 25 September, 2015, world leaders met at the United Nations in New York, where they adopted the Sustainable Development Goals. These 17 goals and 169 targets set out an agenda for sustainable development for all nations that embraces economic growth, social inclusion, and environmental protection. Now, the agenda moves from agreeing the goals to implementing and ultimately achieving them. Across the goals, 42 targets focus on means of implementation, and the final goal, Goal 17, is entirely devoted to means of implementation. However, these implementation targets are largely silent about interlinkages and interdependencies among goals. This leaves open the possibility of perverse outcomes and unrealised synergies. We demonstrate that there must be greater attention on interlinkages in three areas: across sectors (e.g., finance, agriculture, energy, and transport), across societal actors (local authorities, government agencies, private sector, and civil society), and between and among low, medium and high income countries. Drawing on a global sustainability science and practice perspective, we provide seven recommendations to improve these interlinkages at both global and national levels, in relation to the UN’s categories of means of implementation: finance, technology, capacity building, trade, policy coherence, partnerships, and, finally, data, monitoring and accountability

Health, wellbeing and nutritional status of older people living in UK care homes: an exploratory evaluation of changes in food and drink provision

Background Food and drink are important determinants of physical and social health in care home residents. This study explored whether a pragmatic methodology including routinely collected data was feasible in UK care homes, to describe the health, wellbeing and nutritional status of care home residents and assess effects of changed provision of food and drink at three care homes on residents' falls (primary outcome), anaemia, weight, dehydration, cognitive status, depression, lipids and satisfaction with food and drink provision. Methods We measured health, wellbeing and nutritional status of 120 of 213 residents of six care homes in Norfolk, UK. An intervention comprising improved dining atmosphere, greater food choice, extended restaurant hours, and readily available snacks and drinks machines was implemented in three care homes. Three control homes maintained their previous system. Outcomes were assessed in the year before and the year after the changes. Results Use of routinely collected data was partially successful, but loss to follow up and levels of missing data were high, limiting power to identify trends in the data. This was a frail older population (mean age 87, 71% female) with multiple varied health problems. During the first year 60% of residents had one or more falls, 40% a wound care visit, and 40% a urinary tract infection. 45% were on diuretics, 24% antidepressants, and 43% on psychotropic medication. There was a slight increase in falls from year 1 to year 2 in the intervention homes, and a much bigger increase in control homes, leading to a statistically non-significant 24% relative reduction in residents' rate of falls in intervention homes compared with control homes (adjusted rate ratio 0.76, 95% CI 0.57 to 1.02, p = 0.06). Conclusions Care home residents are frail and experience multiple health risks. This intervention to improve food and drink provision was well received by residents, but effects on health indicators (despite the relative reduction in falls rate) were inconclusive, partly due to problems with routine data collection and loss to follow up. Further research with more homes is needed to understand which, if any, components of the intervention may be successful

The Sustainability Perspective: A New Governance Model

Whatever criticisms, there is little doubt that the involvement of enterprises with issues of social concern take greater prominence. This book examines the questions and challenges surrounding the concept and application of the social responsibilities of the enterprise
