The infusion of new technology into the offshore industry has resulted in the introduction of many types and variations of new diving systems. In addition to conventional hyperbaric manned diving and manned submarines, these include atmospheric diving suits, tethered remotely controlled submersibles, one atmosphere diving bells with manipulators and a variety of remotely controlled subsea tools.This paper reviews the current status of such systems, describes operating experiences with typical systems, and suggests criteria for selection of preferred systems. Areas of usage include exploratory drilling, field construction and development, survey, and inspection and maintenance.

The recombinant protein technology considerably promoted the development of rapid and accurate treponema-specific laboratory diagnostics of syphilis infection. For the last ten years, the immunodominant recombinant inner membrane lipoproteins are proved to be sensitive and specific antigens for syphilis screening. However, the development of an enlargedT. pallidumantigen panel for diagnostics of early and late syphilis and differentiation of syphilis stages or cured syphilis remains as actual goal of multidisciplinary expertise. Current review revealed novel recombinant antigens: surface-exposed proteins, adhesins, and periplasmic and flagellar proteins, which are promising candidates for the improved syphilis serological diagnostics. The opportunities and limitations of diagnostic usage of these antigens are discussed and the criteria for selection of optimal antigens panel summarized.

Redundant Systems

Optimal exploration of engineering systems can be guided by the principle of Value of Information (VoI), which accounts for the topological important of components, their reliability and the management costs. For series systems, in most cases higher inspection priority should be given to unreliable components. For redundant systems such as parallel systems, analysis of one-shot decision problems shows that higher inspection priority should be given to more reliable components. This paper investigates the optimal exploration of redundant systems in long-term decision making with sequential inspection and repairing. When the expected, cumulated, discounted cost is considered, it may become more efficient to give higher inspection priority to less reliable components, in order to preserve system redundancy. To investigate this problem, we develop a Partially Observable Markov Decision Process (POMDP) framework for sequential inspection and maintenance of redundant systems, where the VoI analysis is embedded in the optimal selection of exploratory actions. We investigate the use of alternative approximate POMDP solvers for parallel and more general systems, compare their computation complexities and performance, and show how the inspection priorities depend on the economic discount factor, the degradation rate, the inspection precision, and the repair cost.

Selection Of

A procedure that provides information on the suitability of barley for malting and, brewing purposes is described. Three parameters are measured: mash filtration rate, wort viscosity and wort-reducing sugar content, as maltose. Maltose is determined by an auto-analyzer method and this is a satisfactory alternative to the specific gravity procedure for the estimation of percent extract. The addition of these criteria to those already in use enables more discriminatory selection at early generations of barley-breeding programs. The technique requires only one sample extraction and 18 g of laboratory malt.

Negative impact on the environment as a result of economic activity of man increasingly becomes the character of combined pollution of ecotoxicants, including xenobiotics of radiation and chemical nature. In animal husbandry in ecologically unfavorable regions, sorbtion-detoxication technologies based on the complex application of bioprotective substances of different origin are used to reduce the intake and accumulation of xenobiotics, to normalize the physiological state of animals and to obtain safe products. It is necessary to observe certain principles ensuring compatibility of components, a wide range of bioprotective action, efficiency and safety at their use in developing the compositions of such sorption-detoxifying complexes. The article substantiates the criteria that should be followed in creating sorption-detoxifying complexes and presents groups of drugs with different mechanisms of action (sorbents, antioxidants, immunomodulators, adaptogens and other biologically active substances) for inclusion in the formulations of combined compositions.

High-quality food composition data should be representative of national food habits and consumption patterns. They should be generated according to established standard international guidelines so that they are comparable and reliable. Well-designed tables and databases should include a good selection of food components and majority of commonly consumed foods. However, this is often not the case as many tables only include raw foods and a small number of nutrients while processed and fortified foods are lacking. The aim of this review is to focus on the importance of national food composition databases; to show the current status of the problem in Bulgaria; and priorities in the development of a new modern database; in order to attract the attention of stakeholders (government institutions, universities, research institutes, manufacturers and independent specialized laboratories).

Розкривається питання обґрунтування раціональ-ної схеми збирання льону-довгунця із застосуван-ням сільськогосподарських машин загального при-значення. Проведено вибір необхідних та достат-ніх технологічних операцій для збирання льону-довгунця за новою технологією з аналізом кожного окремого елемента. При виборі технічних засобів для збирання льону акцент зроблено не на спеціа-льні льонозбиральні машини, а на техніку, що за-стосовується для збирання інших культур; це ро-бить технологію більш доступною для широкого кола сільгоспвиробників. На основі обґрунтування обраного комплексу технічних засобів складено первинну модель технологічної схеми збирання посіву льону-довгунця. The article reveals the issues of a rational scheme of harvesting flax with the use of agricultural machines for general use. The adequate selection of the necessary and sufficient technical operations for flax harvesting on new technology has been done. When choosing machines for the harvesting of flax a great attention is paid not to special flax pullers but to equipment that is used to harvest other crops, making the technology more accessible to a wide range of manufacturers.
