Background The etiology of Juvenile Idiopathic Arthritis (JIA) is poorly understood. The purpose of this study was to examine the possible influence of early nutrition on later development of JIA. Methods In a population-based prospective birth cohort of 15,740 children we collected nutritional data, ...
At present, cluster analysis and recognition of big data has caused widespread concern. This paper focuses on the classification and identification of moving targets at sea. we use a large amount of raw data of moving targets and big data analysis, data visualization, cluster analysis and prediction ...
During a deep sea diving, divers need a reliable network for dealing with emergencies and packet loss when communicating, so the ad-hoc infrastructure was proposed and could be implemented for a strong connection between diver's devices, however each diver in the underwater network is free to move independently ...
Affordable communication radios for fishermen do not usually have data communication feature which is able to send important informations in text format with the updated coordinate locations. The lack of standard radio for fishermen communication could cause a big risk for fishermen's safety. In this ...
The group divers tracking problem with a 2D high-resolution active sonar is studied in this paper. Probability Hypothesis Density (PHD) filter is famous for its good ability in multiple targets tracking. Instead of travelling in a constant velocity motion model, the activity of divers may be, however, ...
Abstract: Background: One of the major shortcomings in light and semi-heavy ships, such as fishing vessels, is the lack of first aid packages appropriate to the ship's mission and the type of injuries that may be caused by the crew. Therefore, a special bag should be designed to fit the folding stretcher ...
Abstract Anthropogenic noise is a recognized global pollutant, affecting a wide range of nonhuman animals. However, most research considers only whether noise pollution has an impact, ignoring that individuals within a species or population exhibit substantial variation in responses to stress. Here, ...
Background: Pica, the craving and purposeful consumption of nonfoods, is poorly understood. We described the prevalence of pica among women on Mfangano Island, Kenya, and examined sociodemographic and health correlates. Methods: Our cross-sectional study included 299 pregnant or postpartum women in ...
Climate change impacts on the Canadian food system pose risks to human health. Little attention has been paid to the climate change, food security, and human health nexus, resulting in a number of knowledge gaps regarding food system components that are most vulnerable to climate change. The lack of ...
In spite of their perceived value, the widespread implementation of ecosystem services assessments has been limited because of perceptions of being too technical, too expensive, or requiring special expertise. For example, federal estuary management programs have widely used ecosystem services concepts ...
Observations of ocean pollutants are usually spatiotemporally dispersive, while it is of great importance to obtain continuous distribution of ocean pollutants in a certain area. In this paper, a dynamically constrained interpolated methodology (DCIM) is proposed to interpolate surface nitrogen concentration ...
ABSTRACT An organism's ability to respond effectively to environmental change is critical to its survival. Yet, life stage and overall condition can dictate tolerance thresholds to heightened environmental stressors, such that stress may not be equally felt across individuals and at all times. Also, ...
We demonstrated that oral intake of water by two calanoid copepods, Pseudodiaptomus annandalei and Eurytemora affinis takes place and has implications for their ecotoxicology. In the first experiment, copepods were exposed to a dyed medium, which allowed us to visually examine the possibility of water ...
Halving per capita food waste and reducing food losses along production and supply chains is one of the objectives fixed by the United Nations among the Sustainable Development Goals (SDGs). This study employs a system-wide modelling approach, to simulate economic impacts of households' food waste reduction ...
The importance of the maritime vehicles makes necessary the implementation of systems capable of ensure the safety and security. This paper presents an analysis on Automatic Identification System (AIS) data processed with Interacting Multiple Model (IMM) filter in order to help trajectory data analysis ...
Global Navigation Satellite Systems (GNSS) play a fundamental part on the maritime navigation. Beyond positioning, GNSS is key for the operation of multiple interfaces on the bridge of a ship, compromising the skipper skills to perform traditional navigation. Jamming attacks have been recognized as ...
The growth in minor port projects along India's coastline due to burgeoning investor interest and the complete freedom given by the governments to private entrepreneurs to develop and operate these ports have led to several environmental and social costs. Activities around ports such as dredging, cargo ...
Radio communication in Indonesia has developed quite well. However there are still many problems in the use of radio frequency channels although actually it has been regulated by the government. Radio channels for meritime and aviation for example, they both have their own dedicated frequencies so that ...
Japan Aerospace Exploration Agency (JAXA) has some instruments aboard satellites for understanding of marine context. Two satellite-based automatic identification system (AIS) receivers, named SPace-based AIS Experiment 1 (SPAISE1) on the Small Demonstration Satellite-4 (SDS-4) and SPAISE2 on the Advanced ...
Biofouling is an extensively studied problem that results in significant economic and environmental loss. Underwater structures such as ships and pipelines will be subjected to the settlement of marine fouling organisms and then suffer from ship fouling after immersed in seawater. Some marine lives ...
