The aim of present study was to determine the LC50/96 h value of copper sulfate and determine the growth performance of Caspian Sea kutum) Rutilus frisii kutum (fingerlings during 60-days sub-lethal copper (Cu). After acclimation period to two weeks, for determine the LC50/96 h value, total of 27 aquarium ...
Teleost fish genomes are known to be evolving faster than those of other vertebrate taxa. Thus, fish are suited to address the extent to which the same vs. different genes are responsible for similar phenotypic changes in rapidly evolving genomes of evolutionary independent lineages. To gain insights ...
Differences in the chemical composition of calcified skeletal structures (e.g. shells, otoliths) have proven useful for reconstructing the environmental history of many marine species. However, the extent to which ambient environmental conditions can be inferred from the elemental signatures within ...
Aquaculture can significantly lower the environmental impacts compared to producing the same amount of protein on land and also has the potential to meet growth in protein demand. Aquaculture is the farming of any saltwater or freshwater aquatic organism from aquatic plant and crustacean to mollusc ...
In this work, a mathematical approach to the problem of modelling the underwater-to-air optical wireless channel is presented. The seawater interface has been considered as a plain monochromatic seawave where wind stress generates random variations on the surface. Furthermore, a quality of service (QoS) ...
A GIS-based Decision Support System has been developed within the OCEANLIDER project to find optimal placement for green energy generation from oceanic energy. The DSS performs Multi-Criteria Evaluation, MCE, to help in the decision making. The scenario is defined as a combination of the device (power ...
Three different oxygen sensitive nano-materials namely Pt (II) meso-tetra(pentafluorophenyl) porphine (PtTFPP), Tris (4,7-diphenyl-1,10-phenanthroline) ruthenium (II) and Pd (II) meso-tetra (pentafluorophenyl) porphine (PdTFPP) has been coated on one end tip of an optical fiber to form optical fiber ...
Fluorescence based optical sensors has become an attraction in many areas, including industrial, biomedical and environmental applications. Optical sensor developed for water quality monitoring such as dissolved oxygen sensor becomes important such as monitoring the health of aquaculture environment. ...
Presents information and current topics from the Global Communications Newsletter from this publication.
In Italy, the Central Institute for Cataloguing and Documentation (ICCD) rules the cataloguing of the rich and articulated Italian Cultural Heritage through a complex system of shared methodology and formats. ICCD established different catalogue datasheets for each typology of Cultural Good, providing ...
Liposarcoma (LPS) is the most common soft tissue neoplasm in adults and is characterized by neoplastic adipocyte proliferation. Some subtypes of LPSs show aberrations involving the chromosome 12. The most frequent are t(12;16) (q13;p11) present in more than 90% of myxoid LPSs and 12q13-15 amplification ...
This special issues presents some of the work brought to a conference on underwater communication held in 2012 with the aim to present a snapshot of the state of the art in UW communication technologies, both acoustic and optical, and to set the stage for agreeing on some benchmark problems and models ...
The CoMAS project aims to develop new methodologies and tools for the restoration and conservation of submerged archaeological artefacts. One of the project goals is to study the cleaning operations that are intended to remove the living organisms (algae, sponges, molluscs, etc.). These organisms cause ...
Abstract Procedures, photographs, diagrams, results and recommendations are shared from an operation to remove sand plugs from a high pressure deepwater well with a failed lower completion. Specific recommendations minimize risk and provide for the safe handling of sand on the surface as the oil passes ...
Topographic complexity is a key component of habitats that influences communities by modulating the interactions among individuals that drive population processes such as recruitment, competition, and predation. A broad range of disturbance agents affect biological communities indirectly through their ...
The illness of three people due to diarrhetic shellfish poisoning (DSP) following their ingestion of recreationally harvested mussels from Sequim Bay State Park in the summer of 2011, resulted in intensified monitoring for diarrhetic shellfish toxins (DSTs) in Washington State. Rapid testing at remote ...
Background The permanent dominance of Planktothrix-like сyanobacteria has been often reported for shallow eutrophic\hypertrophic lakes in central Europe in summer\autumn. However studies on phytoplankton growth under ice cover in nutrient-rich lakes are very scarce. Lake Nero provides a good example ...
Coastal waters of the Great Barrier Reef (GBR) are contaminated with agricultural pesticides, including the photosystem II (PSII) herbicides which are the most frequently detected at the highest concentrations. Designed to control weeds, these herbicides are equally potent towards non-target marine ...
Abstract Failures provide an opportunity to revisit the existing practices and make necessary improvements in the way operations are designed and executed. Hydrate plug formation in certain operating conditions pose a well-recognized operational hazard. Water can form solid crystalline structure around ...
