An intensive abrasion of the coast of the most popular Lithuanian Palanga health‐resort necessitates consideration of the most effective ways of its stabilization. Based on the data of field investigations and literary sources, the possibilities of Palanga coastal zone regeneration using the sand dredged from the entrance channel of Klaipeda port are considered. Based on the current geodynamic trends of Palanga coastal zone and results obtained by comparative analysis of granulometric composition of sediments dredged from the entrance channel of Klaipeda Port, the optimal possibilities of using the dredged sand for coast regeneration were determined. It was established that formation of underwater sandbar (analogue of natural bar) in the surf zone of coastal sector between the Palanga Pier and Birute Mount at a depth of 3 m would be the best solution for coast regeneration under the current conditions. Santrauka Intensyvi populiariausio Lietuvoje Palangos kurorto jūros kranto arda verčia ieškoti efektyviu kranto stabilizavimo metodu. Pastaruoju metu (2003–2008 m.) atlikti apsauginio paplūdimio kopagūbrio tvirtinimo bei paplūdimio sanašu atsargu papildymo Palangos rekreacineje zonoje darbai leme tik trumpalaiki kranto apsaugos efekta. Straipsnyje, remiantis natūriniu tyrimu bei literatūros duomenimis, ivertintos smelio, iškasamo iš Klaipedos iplaukos kanalo, naudojimo Palangos kranto zonai regeneruoti galimybes. Atsižvelgus i dabartines Palangos kranto zonos geodinamines tendencijas bei atlikus šio ruožo ir iškasamo iš Klaipedos uosto iplaukos kanalo biriu sanašu sudeties lyginamaja analize, nustatytos optimalios iškasamo smelio panaudojimo kranto zonai regeneruoti galimybes. Esant dabartinei situacijai efektyviausias kranto zonos regeneravimo būdas ‐ povandeninio volo (gamtinio sekliaus analogo) 3 m gylyje kranto ruožo tarp Palangos tilto ir Birutes kalno gožos zonoje formavimas. Резюме Интенсивный размыв морского берега в рекреационной зоне самого популярного курорта Литвы – Палангe вынуждает искать эффективные способы его стабилизации. Выполненные за последнее время (2003–2008 гг.) работы по укреплению дюнного вала и попытка пополнить пляж наносами в береговой зоне г. Паланги дали лишь кратковременный берегозащитный эффект. На основе натурных данных в статье оценены возможности использования для регенерации береговой зоны Паланги песка, выкапываемого из подвходного канала порта Клайпеды. Учитывая полученные результаты исследований современных геодинамических тенденций береговой зоны г. Паланги, состав наносов подвходного канала порта г. Клайпеды и изучаемого участка, установлены оптимальные возможности использования добываемого песка для стабилизации береговой зоны г. Паланги. Установлено, что при нынешней ситуации самым эффективным способом регенерации береговой зоны является формирование подводного вала (аналог природного) в прибойной зоне на глубине 3 метров на участке между Палангским мостом и мысом горы Бируте.

The assessment of the suitability of the granulometric composition of the crushed stone aggregates (CSA) for an unbound base and subbase layers of pavement, in the Republic of Serbia is done based on the defined gradation bands, uniformity degree (Cu), coefficient of curvature (Cz), percentage of fines and percentage of particles passing a 0.02 mm sieve. On the other hand, standards which define the quality requirements of aggregates and unbound mixtures for road construction SRPS EN 13242 and SRPS EN 13285 introduce a significantly different approach to the assessment of the granulometric composition suitability. Categories are defined. Each category includes a particular boundary band, tolerances on sieves, differences in values passing each sieve. The categories are defined depending on the field of the application. For seven CSA 0/31.5 mm used for the construction of Corridor XI, a comparative analysis of the granulometric composition suitability was performed according to the requirements of the existing Technical Specifications (TS) of PE "Roads of Serbia" (PERS) and the specified SRPS EN standards. The analysed curves satisfy those technical requirements, but vary in categories from the most severe mixtures of the normal granulometric composition of the GA category, to the open mixtures of the GP category. It was concluded that the principle based on the defining allowed tolerances on the sieves and between the sieves, is more suitable for field control of of the granulometric composition and the good granularity of the aggregates. Technical Specifications should be modified to this approach.

AbstractSocieties are challenged worldwide to maintain or improve the life of an ageing population. In the meantime, it is an opportunity for businesses to develop products and services for the elderly. Participatory design - or co-design - promotes not only to design for, but also with and by older adults. Current studies tend to emphasize more field investigations and co-ideation than evaluation of co- designed outcomes with seniors. We are interested in two 24 hours-innovation contests in 2017 and 2018, yearly involving 10 teams of 3 students, elderly persons as potential beneficiaries and innovation experts. The aim of this paper is to analyse the variability of evaluation of generated projects between the elderly people and the innovation experts. The comparative analysis relies on the grades and ranking of projects against five criteria. Results show that elderly people provide consistent evaluations, but with a positioning slightly shifted compared to the experts. We conclude on recommendations for the evaluation process with a jury including seniors.

Рассмотрен опыт применения разновременных спутниковых фото- и спектрозональных снимков для картографирования изменений природно-антропогенных комплексов ключевых районов береговых (прибрежных) зон за последние 30-40 лет. Показана необходимость анализа природных состояний и антропогенных изменений береговой зоны Тихоокеанской России как условий жизнедеятельности и показателя рациональности природопользования. Показано, что наиболее актуальным является проведение таких оценок в существующих и потенциальных точках роста узловых приморских районах развития. Перечислены пригодные для решения поставленной задачи и доступные в сети Интернет данные дистанционного зондирования, их особенности и характеристики, обусловлены критерии отбора. Рассмотрена методика дешифрирования данных дистанционного зондирования и сложности при использовании разновременных и разнотипных космических данных. Получены геоинформационные слои, отображающие структуру природно-антропогенных комплексов. Проведен сравнительный анализ изменений природных и антропогенных комплексов потенциального узлового района развития Ольга бухта Владимира и южного участка биосферного Сихотэ-Алинского заповедника, условно принятого за эталонный, не затронутый антропогенным воздействием. Установлено, что изменения природных ландшафтов прибрежной зоны Сихотэ-Алинского заповедника происходят в естественном ключе без антропогенного вмешательства, качественных изменений структуры ландшафтов не наблюдается, расчеты изменений значений вегетационного индекса за соответствующие периоды времени демонстрируют положительную динамику, что подтверждает увеличение фитомассы при естественных сукцессиях. Результаты дешифрирования, геоинформационное картографирование и проведенный сравнительный анализ показывают, что критических и даже существенных изменений в ландшафтной структуре рассматриваемого узлового района и территорий, находящихся в зоне его влияния, не произошло. Утверждается, что доминирующее положение лесных и редколесных ландшафтов создаст эффект буфера при дальнейшем потенциальном развитии этих территорий как узловых районов развития в береговых зонах и обеспечит устойчивость этих территорий в отношении сохранения качества окружающей среды при возможном увеличении антропогенной нагрузки.In the article the experience of application of spectrum-zonal remote sensing images occurring at different times for mapping the changes of nature-anthropogenic complexes of the key areas of coastal zones is considered for last 3040 years. Necessity of the analysis of natural conditions and anthropogenic changes of the coastal zone of Pacific Russia as the conditions of ability to live and the indicator of rationality of nature use at a new level is considered. It is shown that carrying out such estimations in the existing and potential growth points- core seaside areas of development is the most actual. The obtainable Internet data on remote sensing, their features, and characteristics suitable for decision of a set task are listed the criteria of selection are conditioned. The technique of interpretation of remote sensing data and complexity, while using the space data of the different type and occurring at different time, is considered. As a result of implementation of the work, the GIS-layers displaying the structure of nature-anthropogenic complexes have been obtained. The comparative analysis of the changes of natural and anthropogenic complexes of potential core area of development Olga-Vladimir Bay and the southern site of the biosphere Sikhote-Alin reserve, conditionally accepted as a natural standard not touched by the anthropogenic influence, has been carried out. It is established that the changes of natural landscapes of the coastal zone of the Sikhote-Alin reserve occur naturally without anthropogenic intervention the qualitative changes of the structure of landscapes has not been observed the calculations of the changes of the values of a vegetative index for the corresponding periods of time show positive dynamics that confirms an increase in phytomass in case of natural successions. The results of interpretation of geoinformation mapping and the carried out comparative analysis show that any critical and essential changes occurred in the landscape structure of the considered key area and on the territories located in the zone of its influence. It is approved that the dominating position of the forest and open woodland landscapes will create buffer effect and will provide stability of these territories relatively to preservation of quality of the environment in case of the possible increase in anthropogenic load if further potential development of these territories happens as the key areas of development in coastal zones.

Field campaigns were conducted in 1981 and 1982/83 on the Dutch coast near Egmond. Measurements were made of surface elevations, water velocities and sediment concentrations in 3 to 8 surf zone locations and 2 to 5 offshore locations simultaneously. A total of 50 measurement series was obtained under a variety of weather conditions, resulting in offshore wave heights of 0.2 to 4.6 m. A description is given of the field set-up, the instruments and measurements, and the collected data. The quality of the various measurement systems and the data produced has been investigated extensively by intercomparison of instruments and devices in the field. The results are reported here.

The Mean

During storm surges considerable wave energies are dissipated in surf zones; the energy transfer rates are in the order of one up to two powers of ten higher than outside the surf zone. A breaker parameter s introduced by FOHRBOTER (1974) with regard to a quantitative breaker classification, especially of the intermediate types between surging and spilling, was found to be convenient for practical application. The breaker parameter e is in close relation with the horizontal asymmetry parameter a of the breaking wave. With decreasing breaker parameter the asymmetry is increased and reverse. Within the longshore currents macro-turbulences were discovered. The periodical fluctuation parameter y was found to increase nearly linearily with decreasing breaker parameter; the narrower the area is, where the main energy is dissipated the smaller becomes the mean periodical fluctuation which seems to be independent of the wave period but reaches up to 7 and more fluctuations within the wave period. The mean longshore currents velocities reached up to 1.5 m/s above the seabottom; th£ coefficient of variation was scattering considerably between 400 per cent at low velocities (v,= 0.1 m/s) and 20 per cent at the highest velocities (v.= 1.5 m/s). The instantaneous longshore current velocities were nearly symmetrically distributed around the mean velocity, the mean amplitudes were nearly constant and reached approx 0.35 m/s whereas the periodical fluctuation decreased from 2.6 s at low mean velocities up to 1.7 s at high velocities.
