Eating healthy is the key to a healthy life. But nowadays, it is getting increasingly difficult to decide which food is healthy and which is not. Our foods are so frequently adulterated by harmful preservatives like formalin that they have become potential dangers to our health. Formalin, which is a ...
With the increasing needs for long-term fossil fuels, the Arctic regions of the world have opened up to opportunities in oil/gas development, Northern transportation, and sea routes to reduce travel times between Europe and Asia are also increasing interest in commerce along those routes. The increased ...
The cooperative marine autonomous system (MAS), a combination of an autonomous surface vehicle (ASV) with an autonomous underwater vehicle (AUV), would provide researchers, governments, and conservationists unprecedented reach to study the marine environment and prepare for the effects of climate change. ...
Cryptocurrency mining can be said to be the modern alchemy, involving as it does the transmutation of electricity into digital gold. The goal of mining is to guess the solution to a cryptographic puzzle, the difficulty of which is determined by the network, and thence to win the block reward and transaction ...
The article presents the ecological problems of utilization of spent activated sludge, which is a waste after biological treatment of wastewater and ways of their solution. A literature review devoted to modern methods of recycling and recycling of spent activated sludge is presented. The methods of ...
Reproduction is one of the most persistently generative themes in the history of science and cinema. Cabbage fairies, clones and monstrous creations have fascinated filmmakers and audiences for more than a century. Today we have grown accustomed not only to the once controversial portrayals of sperm, ...
Taxonomically, Argentine mackerels were first considered as Scomber japonicus marplatensis and later as Scomber japonicus Houttuyn 1782, although, in the last years, different studies have suggested that South Atlantic mackerel species belongs to Scomber colias Gmelin 1789. These latter results, incorporated ...
The National Oceanic and Atmospheric Administration's Ecosystems and Fisheries Oceanography Coordinated Investigations biophysical mooring site 2 (M2, 56.9°N, 164°W) time series, one of the longest running time series of its kind, has provided near-continuous biophysical measurements of the southeastern ...
Billions of contributions are made every day across multiple online communities and social media websites in the form of social messages, social blogs and online discussion. The aim of this paper is to identify such comments and posts which are racist and malicious in nature so that they could be effetely ...
This article reviews and analyzes the needs of Earth observation (EO) services' users, stakeholders, and beneficiaries. It identifies the key elements of the value chain of the European EO infrastructure and builds a comprehensive knowledgebase of those elements, represented as a relational database. ...
This research aims to develop a concrete-like material for underwater construction applications by using fluorogypsum (FG, an industrial by-product of hydrofluoric acid production), class C fly ash, and type II Portland cement. Two Response Surface Models (RSMs) were derived based on compressive strength ...
In this paper we present a method for generating healthy diets for elderly people. The method proposed is based on the Crab Mating Optimization Algorithm, which is inspired from the breeding behavior of crabs in nature. In our case the generated diet is composed of several meals per day and it can be ...
This paper proposes a method for detecting moving objects on an underwater video. Video obtained using an underwater camera to capture the environmental conditions of the area. This research is the initial stage of the underwater surveillance system. Underwater surveillance system enables objects passing ...
Moorings with a subsurface float or a benthic lander with onboard positive buoyancy are often coupled to a heavier expendable iron anchor to hold position on the seafloor. Releasing the weight is the critical first step of a mooring or benthic lander recovery. This paper describes a hierarchal selection ...
In 2015, the Hanna Shoal region of the Chukchi Sea shallower than the 40 m isobath was withdrawn from outer continental shelf oil and gas exploration, a move the White House noted was designed to protect areas of “critical importance ... for marine mammals, other wildlife, and wildlife habitat”. Arctic ...
Increased maritime shipping activity by larger ships is elevating the risk for maritime accidents and environmental impacts. Starting in 2004, these risks are being ameliorated by Automatic Identification System (AIS) technology. Similar to airplane transponders, AIS transmits a vessel's name, type, ...
Arctic and subarctic conditions represent some of the most challenging environments to make long-term in situ oceanographic measurements. These areas bring the normal challenges of deep water, turbidity, uncertain bottom types and, in areas such as Cook Inlet, some of the world's largest tidal height ...
Monitoring the vast expanse of oceans presents a daunting challenge: how to take sufficient high-quality measurements with a relatively small group of specialized scientists and limited resources. Despite advances in remote sensing and autonomous technology, the oceans remain under-explored and under-sampled. ...
Alaska's Kenai fisheries are managed for maximum efficiency while ensuring fair allocation across multiple stakeholder groups and long term sustainability of the fishery. Managers must work to meet the fishery's goals while adapting their commercial and subsistence eco-service management practices to ...
This paper discusses the use of echosounders with forward-looking capabilities (navigation sonar) as scientific instruments for the acquisition of sensor data useful both for short term and long term measurement of Arctic system parameters and variables for the scientific investigation of environmental ...
