В статье приводятся результаты экспериментальных исследований распространения низкочастотных акустических сигналов (33 Гц) на побережье залива Петра Великого Японского моря. Источник акустических сигналов опускался с борта маломерного судна в воду, а приемные системы были у береговой черты в воде и на суше. За счет использования трехкомпонентных виброметров стало возможно разделить принятые сигналы на различные типы волн (продольные, поперечные и поверхностные). Получены предварительные результаты расчета скоростных характеристик приходов различного типа волн на виброметры. The article presents the results of experimental studies on the propagation of low-frequency acoustic signals (33 Hz) on the coast of Peter the Great Bay of the Sea of Japan. The source of acoustic signals descended from the board of a small boat into the water, and the receiving systems were at the coastline in water and on land. Through the use of three component vibrometers, it has become possible to divide the received signals into various types of waves (longitudinal, transverse and surface waves). The preliminary results of calculating the speed characteristics of the arrival of various types of waves on vibrometers are obtained.

One of the goals of the Vrokastro Survey Project, based in west-central Mirabello, eastern Crete, was to identify a site within the boundaries of the survey study area worthy of further investigation, including excavation. The settlement selected, based on its complexity and long lifespan, was Priniatikos Pyrgos, a harbour community and ‘gateway’ of the Vrokastro region. As a preliminary to excavation, the Istron Geoarchaeological Project was initiated in order to document the nature, condition, and resources of this site and its coastal environment. This multidisciplinary program was implemented through fieldwork, laboratory analyses, and geophysical prospection. Results include new data concerning the industrial aspects of Priniatikos Pyrgos, the changing topographical situation of the site and coastal zone, the overall size of this diachronic harbor settlement, and the regional resources involved in ceramic and metallurgical production.

Hawaii's beaches are of great economical and. social value; they serve a variety of purposes and are valuable both to residents and tourists alike. Like in many other parts of the world, many of Hawaii's beaches are in a state of erosion and measures of improvement must be designed to cope with this problem. Although in the past several studies have been undertaken to evaluate Hawaii's beach systems and to analyze possible measures of improvement, this study aims at an in-depth analysis of the physical factors at work in the coastal zone. A thorough understanding of these processes, it is felt, is indispensable for the application of sound and economic measures in stabilizing and maintaining Hawaii's beaches. This paper describes some preliminary results of field studies conducted in Waikiki Beach. The latter beach was chosen because of the pressing need for improvements and because of its convenient location. In order to project this study against the proper background, a short review of the general characteristics of Hawaiian beaches precedes the results of the Waikiki Beach study.

The results of field observation for recreation load on Sevastopol beach “Vasileva balka” from May till October 2016 was presented. Maximal attendance of the be3ch was registered during July – mid-August. Median of guest number from 9 till 19 was 380, minimum – 130, maximum – 625 persons. Maximal and average actual recreation loads on the beach did not exceed values estimated by SanPiN norms.

Maricullure in coastal zone, such as the bays, inlets, or lagoons in coral reef is becoming more important in the world fishery activities. In Indonesia, some culture experiments are being conducted, such as for oyster (Crassostrea tuculata BORN) in Banten Bay, and seaweed (Eucheuma spinosum) in Samaringa Islands (Central Sulawesi) and Talang islands (Riau Archipelago), while culture of cockle (Anadara granose LIN.) based on a simple method have been conducted by local fishermen from Ketapang (West Jawa) since several years ago. Some preliminary results of culture experiments are given.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

AbstractThe records of sunspot number, sunspot areas and sunspot locations gathered over the centuries by various observatories are reanalysed with the aim of finding as yet undiscovered connections between the different parameters of the sunspot cycle and the butterfly diagram. Preliminary results of such interrelationships are presented.

Several outstanding problems affecting the existing parallaxes should be resolved to form a coherent system for the new General Catalogue proposed by van Altena, as well as to improve luminosity calibrations and other parallax applications. Lutz has reviewed several of these problems, such as: (A) systematic differences between observatories, (B) external error estimates, (C) the absolute zero point, and (D) systematic observational effects (in right ascension, declination, apparent magnitude, etc.). Here we explore the use of cluster and spectroscopic parallaxes, and the distributions of observed parallaxes, to bring new evidence to bear on these classic problems. Several preliminary results have been obtained.

Preliminary results reported last year on the ion etching of tobacco mosaic virus indicated that the diameter of the virus decreased more rapidly at 10KV than at 5KV, perhaps reaching a constant value before disappearing completely.In order to follow the effects of ion etching on TMV more quantitatively we have designed and built a second apparatus (Fig. 1), which incorporates monitoring devices for measuring ion current and vacuum as well as accelerating voltage. In addition, the beam diameter has been increased to approximately 1 cm., so that ten electron microscope grids can be exposed to the beam simultaneously.
