The Lake Kinneret Ecosystem has undergone significant modification since mid-1980`s which particularly were: The previous trophic status of Phosphorus limitation was modified to Nitrogen limitation; the long-term domination of Peridinium gatunenze (PRG) was declined and replaced by Cyanobacteria, Chlorophytes and Diatoms. The distribution enhancement of Harmful Cyanobacteria (HFCB) in Lake Kinneret initiated in summer 1994 when a bloom of Aphanizomenon ovalisporum was documented followed by several studies about the outbreak of HFCB were carried out [1,2]......

The world’s total primary energy consumption (TPEC) has recorded a steep rise within the last decades reaching 150,000,000 GW.h in 2015 [1]. About 57% growth of this value is expected by 2050 owing to the rapid industrial development and urbanisation that has occurred globally. Presently, fossil fuels including petroleum and natural gas are the main sources of energy [2]. According to the statistical review of the world’s energy, which is annually published by British Petroleum (BP), consumption of energy has extensively increased during the last decade [3]. The reasons for increases in energy consumption include industrial development, population growth and the inauguration of new technologies. Industrial developments in different applications require excessive energy for operations using either electricity or heating energies. Elect..... ReadMore

Generally, phytoplankton exhibits high species diversity and wide range of variation which makes them most successful primary producer in contemporary global oceanographic regimes. When compared to its counterpart of terrestrial ecosystem, phytoplankton species diversity is twelve-fold lower, however, taxonomic divisions are eight times higher than terrestrial plants. Therefore, it is important to investigate the detailed composition of phytoplankton and study their spatiotemporal distribution in the marine environment. In the present review, we have assessed the detailed community composition of cormophytic phytoplankton with their variability in the world oceans...... ReadMore

Decipher what the Earth’s ancient environment was like thousands, may be millions of years ago became one of the most objectives of paleontology and Archaeology. Nevertheless, the significant fluctuations of the microfauna contents and the dominance phases of alternation between benthic and planktonic foraminifera reveal changes as well in the depositional environment. The results of this study indicate that the supposed depositional environment is a calm and relatively deep environment which can be located around the middle to the external platform, where the depth of waters exceeds 200 m. These waters are characterized by a poor percentage in oxygen (Figure 1a)...... ReadMore

In this paper, a probe on the impact of Hall effects on the flow of an oscillatory convective MHD viscous, incompressible, radiating and electrically conducting second-grade fluid in a vertical porous rotating channel in a slip flow regime is carried out. The fluid is assumed to be gray, absorbing and emitting radiation in a non-scattering medium. It is presupposed that MHD flow is laminar and fully developed. In order to use the regular perturbation technique, the solutions of velocity and temperature distributions for the governing flow are obtained. The profiles of velocity and temperature are presented graphically. On the other hand, the skin friction coefficient and the Nusselt number are evaluated numerically and presented in the form of tables, examined and discussed for various values of the flow parameters that govern it......

In recent years, the intensive study of deep-sea ecosystems (continental slopes, seamounts, depressions and troughs) of the world ocean has received increased attention due to the high level of endemism of their biota and extreme vulnerability to any impacts, especially from humans [1,2]. While in the past, researchers aimed to obtain knowledge, mainly on the qualitative and quantitative composition of the population of deep-sea ecosystems, at the present stage it is becoming increasingly important to assess the human impact on them, to ensure the conservation of biological and genetic diversity, the safe and sustainable use of biological resources and their protection from destruction in the course of human economic activities (fishing, mining, shipping, etc.)......

In both Côte d’Ivoire and Africa, unlike men, women suffer from low levels of education. She is thus confronted with problems of integration into the social fabric due to her lack of education. Fish farming and related activities that do not necessarily require a high level of intellectual knowledge are an opportunity for them. This study aims at showing how fish farming contributes to the integration of women into the Ivorian social fabric, particularly in the municipality of Bingerville. The work method used is documentary research and field surveys conducted on fish farms and fish farm marketing sites identified in the study area. The results of our analyses reveal that fish farms initiated in lagoons and lowlands are a source of job creation for women...... ReadMore

The estuary of Bahía Blanca (39° 03′44 ″ S 62° 04′00 ″ W) occupies a large coastal area south of the province of Buenos Aires, Argentina. This area includes urban centers, several industrial parks and deep-water ports. The parasites sensitivity to pollutant and environmental disturbances makes many taxa useful indicators of environmental health and anthropogenic impact. In the present study, the variation in helminth communities of Sympterygia bonapartii was analyzed retrospectively after a period of 18 years. Infra-communities harbored an average of four times more parasites and became less equitable. A gradual increase in organic matter added to the parameters synergy caused by untreated sewage discharges, seems to have been the most important impact on helminth communities, altering the abundance, dominance and eveness. The ..... ReadMore

The question of deep and shallow decompression stops is interesting and fraught with controversy in diving circles and operations, training, exploration and scientific endeavors. Plus, fraught with some misunderstanding which is understandable as the issues are complex. We accordingly detail a short history of deep and shallow stops, physical aspects, staging differences, diving tests, models, data correlations, data banks, diver statistics and DCS outcomes for diving amplification. Pros and cons of deep stop and shallow stop staging are presented. Misinformation is corrected. Training Agency Standards regarding deep and shallow stops are included. A tabulation of well-known and popular dive computers and software algorithms is given. From diving data, tests, DCS outcomes, data banks and field usage, we conclude that both deep stops and s.....

It is known that in traditional power engineering hydrogen may be one of the first primary source of equipment damage [1]. This problem has high actuality for both nuclear and thermonuclear power engineering [2]. Particularly reactor pressure vessels (RPV) of the WWER-440/230 project was manufactured without stainless cladding that were in contact with primary circuit water and accessible for hydrogen as a product of RPV wall corrosion. Analysis of the combined radiation-hydrogenation embrittlement of the 48TS type vessel steel was performed in [3] where at the mention of the American [4] and own data question concerning unknown source of hydrogen in metal that was irradiated in nuclear reactor in hermetic ampoules (was named as “irradiation-produced hydrogen” (IPH) was raised......

The earth and atmosphere for millions of years created the animal and plant worlds. Together with them, water quality also developed. In constant motion, water formed a continuous chain of transformation in the bodies of living things and leaves of plants. The harmonious interaction of water, atmosphere and biota has led to the existing balance - the circulation of water through the atmosphere, where the properties of water acquire their initial starting quality for new transformations. Man, in the process of industrialization, turned water into a working tool. He made the water perform unnatural functions for her. Pressure, transportation, spraying, storage, boiling, burning, poisoning of ever increasing volumes of water have led to a change in the quality of water in the atmosphere. Changes in the quality, volume and rate of evaporati..... ReadMore

Investigation of foraminifera assemblage through thirtyt-wo surface samples along the transect in Itapitangui river mangrove was done in july / 89. Foraminiferal fauna composed mainly of Ammotium salsum, Arenoparrella Mexicana, Haplophragmoides wilberti, Miliammina fusca and Trochammina inflata occur on mangrove area of Cananeia-Iguape estuary-lagoon system at bottom salinity range from 6 to 30, bottom temperature range from18 -9°C and organic carbon percentage values range from 0.47 to 5.7. The low diversity pattern of foraminiferal population inhabiting the mangrove area of Itapitangui River and the lack of foraminiferal zonation is similar to that encountered in mangroves from all over the world. In July 1989, a survey of foraminifera zoning was carried out by means of thirty-two surface samples along ..... ReadMore

This investigation is the novel study, which is contacted along the Malaysian coastal water to implement the potential of TanDEM-X satellite data for retrieving sea surface current. In this view, the main objective of this investigation is to exam the multichannel MAP height estimator for retrieving sea surface current pattern as a function of the tidal elevation. In-deed, TanDEM-X satellite data have an inordinate prospective for modeling the sea surface parameters, for instance, sea surface current flows and the physical parameters of ocean wave spectra i.e. wavelength and significant wave height. Consequently, TanDEM-X satellite data are the expression of the satellite operation flying with the two satellites in an exactingly measured substance with a consistent baseline between 250 and 500m.

Sidedness of divergence helps resolve a present discordance in our understanding of upwelling in the Southern Ocean, and thus it contributes to the evolving recognition of the oceans� overturning circulation. Divergence can be two-sided (one water mass rises and moves apart in two flows, as is commonly envisioned) or one-sided (one water mass rises and moves away from another that does not move in the opposite direction). Upwelling in the Southern Ocean can be envisioned as a one-sided divergence north of a two-sided divergence. In the more northern one-sided divergence, deep to intermediate waters above or from North Atlantic Deep Water (NADW) upwell into the Antarctica Circumpolar Current (ACC) and move north. In the more southern and two-sided divergence, North Atlantic Deep Water (NADW) upwells and diverges southward into the Antarcti..... ReadMore
