    This paper discusses the problems of application and choice of cryptographic standards taking into account user requirements and preferences. User profiles are created by means of the ontology apparatus. On the basis of user profiles and document features an appropriate set of documents is formed, the elements of which are then arranged according to the degree of compliance to user requirements. Various filtration methods, such as collaborative filtering, content analysis and filtering, as well as hybrid methods combining both approaches, are used. Thus, a recommender system for choosing cryptographic standards and algorithms is built. If there are several user selection criteria, it is reasonable to apply an integral index of object’s relevance to user preferences. This index is defined as the weighed sum of the particular indices.Π’ Π΄Π°Π½Π½ΠΎΠΉ ΡΡ‚Π°Ρ‚ΡŒΠ΅ ΠΈΡΡΠ»Π΅Π΄ΡƒΡŽΡ‚ΡΡ ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΡ‹ примСнимости ΠΈ Π²Ρ‹Π±ΠΎΡ€Π° криптографичСских стандартов с ΡƒΡ‡Π΅Ρ‚ΠΎΠΌ ΠΏΡ€Π΅Π΄ΠΏΠΎΡ‡Ρ‚Π΅Π½ΠΈΠΉ ΠΈ Ρ‚Ρ€Π΅Π±ΠΎΠ²Π°Π½ΠΈΠΉ ΠΏΠΎΡ‚Π΅Π½Ρ†ΠΈΠ°Π»ΡŒΠ½ΠΎΠ³ΠΎ ΠΏΠΎΠ»ΡŒΠ·ΠΎΠ²Π°Ρ‚Π΅Π»Ρ.

    Evaluation of the region-specific risks of accidental radioactive releases from the European Spallation Source

    Get PDF
    The European Spallation Source (ESS) is a neutron research facility under construction in southern Sweden. The facility will produce a wide range ofradionuclides that could be released into the environment. Some radionuclides are of particular concern such as the rare earth gadolinium-148. In this article, the local environment was investigated in terms of food production and rare earth element concentration in soil. The collected data will later be used to model thetransfer of radioactive contaminations from the ESS

    Agricultural Development in Asia and Africa

    Get PDF
    This Open Access book explores the multifaceted nature of agricultural and rural development in Asia and examines the extent to which the Asian experience is being replicated in contemporary Africa. This volume compiles the works of top scholars who provided analyses and evidences from household-level surveys collected for many years in several parts of Asia and Africa. The most important finding presented in this book is that African agricultural development has evolved following the pathways of Asian agricultural development. The common pathways are borrowed technology from abroad and adaptive research in rice farming; secured property rights on natural resources; adoption of ICTs; investments in human capital, including training; and launching of the high-value agriculture. In both continents, agricultural development started in the crop sector, which had a strong tendency to induce the dynamic development of other sectors in rural areas

    Guidelines for the identification and management of lead exposure in pregnant and lactating women

    Get PDF
    "Lead exposure during pregnancy and breastfeeding can result in lasting adverse health effects independent of lead exposure during other life stages. However, to date there has been limited guidance available for clinicians and the public health community regarding the screening and management of pregnant and lactating women exposed to high levels of lead. Recognizing the need for national recommendations, the Centers for Disease Control and Prevention and the Advisory Committee on Childhood Lead Poisoning Prevention convened a workgroup of recognized experts to review the existing evidence for adverse effects of past and current maternal lead exposure on maternal health and fertility and on the developing fetus, infant, and child in prenatal and postnatal states and to propose evidence-based strategies for intervention. These Guidelines for the Identification and Management of Lead Exposure in Pregnant and Lactating Women are based on scientific data and practical considerations regarding preventing lead exposure during pregnancy, assessment and blood lead testing during pregnancy, medical and environmental management to reduce fetal exposure, breastfeeding, and follow up of infants and children exposed to lead in utero. The guidelines also outline a research agenda that will provide crucial information for future efforts to prevent and treat lead exposure during pregnancy and lactation. Further research is needed for a better understanding of lead's effect on pregnancy outcomes and infant development; lead kinetics across the placenta and in breast milk and their relationship to long-term health effects; genetic susceptibility to damage from lead; as well as the pharmacokinetics, effectiveness, and safety of chelating agents in the pregnant woman. Research is also needed to address important clinical and public health needs including validation of risk questionnaires for pregnant women, optimal timing of blood lead testing, and effective strategies for identification and treatment of pica in pregnant women." - p. iPreface -- Executive summary -- Summary of public health actions based on maternal and infant blood lead levels -- Members of the Work Group on Lead and Pregnancy -- Acknowledgments -- Members of the Advisory Committee on Childhood Lead Poisoning Prevention -- Glossary . -- 1.

    Automation of pulp wood measuring

    Get PDF
    The pulp industry in Sweden has played an important role in the country’s economy and still does. It is an energy and raw material-consuming industry with a high degree of industrialization and automation. Much work has been done to reduce labor costs by replacing manual work with technology. In this context, it is remarkable that no precise instrument has been created to help the measurement personnel in their time-consuming work on determining the volume and value of pulpwood delivered to the mills. The delivery to and measuring of raw material at the mills plays an important role in the logistics from the forests to the industry. Measurements have to be performed accurately in order to work as a basis of payment. The way the measurement procedure works today is that one truck has to stand still blocking other trucks when its load is being measured. In the future, it might be possible to speed up this procedure and reduce the manual work with automated measurement. However, transforming an acknowledged method is no easy task, it costs money and patients. For this reason it would be of interest to see whether it would be worth making the effort and whether it would be in the interest of the industry to adopt the new technique. The aim of this thesis is to determine what benefits that exist when it comes to automation of pulp wood measurement and to determine the possibility of gaining these benefits when installing the equipment. Investigations were made at seven mills. The collection of data for the calculations was made by means of interviews with a standardized questionnaire mailed in advance to the respondents. The respondents were personnel at the pulp mills and in the wood measurement organizations. These data were then processed in order to make net present value calculations and sensitivity analysis possible. The calculations show that the investment is beneficial even with hard constraints in investment horizon and cost of capital. According to most respondents the benefits discussed are possible to realize. The laser measurement can be installed and adapted to Swedish conditions with benefit for most plants. The risks that can have an impact on the outcome of an investment are much due to the new and in Sweden almost untested technology. Because of this there is a risk in the start up phase and how easy the technology fits in to the measurement regulations that exists today. The forecast for the implementation of this new technology however looks good. To get leverage to the investment it is of importance not only to try to adapt the new technology to the circumstances today but also be willing to adapt parts of the measuring to gain extra effect of the new technique
