Mayu Island (formerly known as Oyster Island) is a very small island of 7,284 squared-meter located off the north-western coast of Myanmar, Bay of Bengal. In mid-April 2006, Cyclone Mala had caused partial damages to the stone revetment. Over the years, the raft foundation of the lighthouse was badly affected and starting to give way. In addition, the safety of the Navy personnel stationed on the island is a major concern as well. Therefore, rectification works has to be carried out to protect the island from total destruction. This paper presents the proven viability of integrating geotextiles tubes into a rock revetment facing harsh weather conditions from the open sea, and the fastest method of filling up geotextile tubes.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/fsTsdqbVAc4

In the 13 years which have elapsed since Mr. Blanford published his paper on the Winds of Northern India, very great additions have been made to our knowledge of the meteorology of the country. The carefully organised system of observations, commenced in Bengal and the North-Western Provinces, has been extended to include the whole of India, and placed under the direction of Mr. Blanford himself, aided by local officers in all the larger provinces. Verified instruments have been supplied to all the stations, and the elevations of these above sea-level have been determined by connecting them with the lines of spirit-levelling, carried inland from the coast, in various directions, by the officers of the Great Trigonometrical Survey; or, where this was impracticable, by spirit-levelling to some of the trigonometrical stations of the Survey. In this way, trust worthy and intercomparable series of barometric observations, extending over ten years or more, have been obtained for all the more important stations. At the same time, the diurnal variations of the barometer at certain selected stations have been determined by long-continued series of hourly observations, with the object of enabling us to reduce the readings made in the ordinary way (usually at 10 a. m. and 4 p. m.) to time daily means. Simultaneously with the collection of this immense quantity of accurate and reliable barometric data, observations have been made of temperature, humidity, cloud, wind, and rain. Latterly also barometric and wind charts of the Bay of Bengal have been prepared from observations made on board ships navigating those waters. During these 13 years, the winds prevailing over the Indian continent and the Bay of Bengal, and their relations to the distribution of pressure at sea-level, have been discussed from time to time, both in their normal aspects for each month or season and in their abnormal or disturbed conditions during the passage of storms. The latter conditions in particular have been very fully described by Mr. Eliot in his numerous reports on cyclones in the Bay of Bengal, while the former have been noticed in the annual reports on the meteorology of India, in occasional papers appearing in the ‘Indian Meteorological Memoirs,' and latterly in a broad and general review in Mr. Blanford’s great monograph on the Rainfall of India.

Цель исследований: изучение коллекционного питомника лука репчатого по основным хозяйственно ценным признакам в условиях Астраханской области. Исследования проводились в условиях вегетации 20172018 годов в Черноярском районе, на опытном участке Прикаспийского НИИ аридного земледелия, расположенном в северо-западной части Астраханской области. Почвы на участках изучаемой зоны светло-каштановые, разной степени солонцеватости, занимают доминирующее положение в почвенном покрове рассматриваемой территории. В целом, погодные условия были неблагоприятными для выращивания лука репчатого. Опыты были заложены в соответствии с общепринятыми методиками согласно агротехнике лука репчатого в условиях Астраханской области. Для проведения исследований в 20172018 годах были использованы образцы из генетической коллекции ВНИИГР имени Н.И. Вавилова, а также образцы, отобранные в предыдущие годы. Коллекционный питомник лука репчатого был представлен 50 образцами, 26 из них выделились в годы исследований. Посев семян коллекционного питомника лука репчатого проводили в один срок: 3 мая (во все годы исследований). Получены результаты по выделившимся образцам коллекционного питомника лука репчатого по фенологическим фазам. Массовые всходы были отмечены на 1222 сутки от посева. Фенологическая фаза начало формирования луковиц была отмечена на 6168 сутки от посева. К раннеспелым образцам лука репчатого в коллекционном питомнике можно отнести: Сорокозубку, Suttons improved, Red mom, Nothern. Среднеспелыми образцами за годы изучения себя показали: Red Extra, Марковский, Vertus, Selfed, Jetset, Sillani Sargo. По основным хозяйственно ценным признакам выделились 15 коллекционных образцов. По выделившимся образцам лука репчатого средняя урожайность отмечена у пяти образцов: Maravanka, Алмадон, Southport, Selfed, Местный (Грузия), средняя масса товарной луковицы составила 151,6 г. По товарной урожайности выделилось три коллекционных образца: Zillani, Suttons improved, Encore. У сортообразца Марковский было отмечено 70 товарных вызревших луковиц. Максимальная масса товарной луковицы 206,0 г была отмечена у коллекционного образца Cebola.The purpose of the present research was: to study the collection nursery of bulb onions on the main economic valuable features in the conditions of the Astrakhan region. The research was carried out in the conditions of the 20172018 vegetation in the Chernoyar district, on the experimental section of the Caspian research Institute of Arid agriculture, located in the north-western part of the Astrakhan region. Soils on the areas of the studied zone light chestnut, different degree of salt content, occupy a dominant position in the soil cover of the considered territory. On the whole, weather conditions were unfavourable for the cultivation of bulb onions. The experiments were laid down in accordance with the generally accepted methodologies according to bulb onions agricultural machinery in the Astrakhan region. For research in 20172018 samples from the genetic collection VIR named after N.I. Vavilov were used, as well as samples taken in previous years. The collection nursery of bulb onions was represented by 50 samples, 26 of them stood out during the years of research. Sowing of seeds of collector nursery of bulb onions was carried out in one term: on May 3 (in all years of research). Results were obtained for selected samples of the collection nursery of onion by phenological phases. Mass shoots were observed on 1222 days from sowing. The phenological phase the beginning of the formation of the follicles was noted in 61 to 68 days from sowing. Early-maturing examples of onions in the collection nursery include: Sorokozubka, Suttons improved, Red mom, Northern. During the years of study, red Extra, Markovsky, Vertus, Selfed, Jetset, and Sillani Sargo showed themselves to be the middle-aged samples. According to the main economically valuable features, 15 collection samples were distinguished. According to the selected samples of onion, the average yield was noted in five samples: Maravanka, Almadon, Southport, Selfed, Local (Georgia), the average weight of the commodity bulb was 151.6 g. Аccording to the commodity yield, three collection samples were distinguished: Zillani, Suttons improved, Encore. In the Markovsky variety, 70 of commercially Mature bulbs were observed. The maximum mass of a commodity bulb of 206.0 g was noted in the collection sample of Cebola.
