Liverwort Blasia pusilla L. recruits soil nitrogen-fixing cyanobacteria of genus Nostoc as symbiotic partners. In this work we compared Nostoc community composition inside the plants and in the soil around them from two distant locations in Northern Norway. STRR fingerprinting and 16S rDNA phylogeny ...
Sonars on navy, research and fishing vessels are often "blinded" by the presence of air bubbles in the sonar beam. To improve the sonar's performance, several authors propose adjusting the filter settings on the signal returned by the sonar, to filter out the disturbances originating from the presence ...
With the advent of new naval ship types, interest in reducing the structural weight and lowering vertical center of gravity (VCG) while meeting military safety requirements has increased dramatically in recent years. Ship structural optimization is usually a mixed discrete continuous design problem ...
The introduction of the Energy Efficiency Design Index (EEDI), which is applicable for various types of new-built ships after January 1, 2013 raised concerns regarding the sufficiency of propulsion power and steering devices to maintain maneuverability in adverse conditions. This was the motivation ...
This paper, which is in part an update to Beck and Reed (2001), discusses current developments in seakeeping computations for ships maneuvering in a seaway. First a brief historical background is given in order to put present computations in context. Then a detailed discussion of the necessary components ...
Inaccessible voids are commonly found within a ship's hull. By nature of a ship's construction, these typically cannot be coated traditionally, potentially leaving the steel subject to corrosion. Specifically, inaccessible voids with one or more boundaries exposed to seawater, standing water, or a water-filled ...
In the present work, we developed a computerized methodology to optimize the design of an off-grid hybrid solar community electrification. It is based on a 3-phase process: (1) Determining the load profile of the village by making a power balance, the average daily consumption and establishing the load; ...
Multiagent patrolling in adversarial domains has been widely studied in recent years. However, little attention has been paid to cooperation issues between patrolling agents. Moreover, most existing works focus on one-shot attacks and assume full rationality of the adversaries. Nonetheless, when patrolling ...
We discovered the problems in ship hull inspection operation and build our autonomous underwater vehicle (AUV). The Autonomous Underwater Vehicles will be developed at Universiti Teknologi Malaysia, Kuala Lumpur, Malaysia with the aim of making a research platform in the field of autonomous underwater ...
Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank ...
ABSTRACT The study of aplacophoran mollusks (i.e., Solenogastres or Neomeniomorpha and Caudofoveata or Chaetodermomorpha) has traditionally been regarded as crucial for reconstructing the morphology of the last common ancestor of the Mollusca. Since their proposed close relatives, the Polyplacophora, ...
Eel is a high economic value commodity. International market demand for this fish is high enough, so a lot of farmers cultivated it with main objective of export. The problem in eel fish farming is the seeds that have to be taken directly from nature. This impacts to the more rapidly declining of eel ...
This paper presents energy and power evaluations on propulsion and generation systems related to a research vessel, named G. DALLAPORTA. This vessel is used by the National Research Council of Italy for oceanographic campaigns, which are generally carried out in the Mediterranean Sea. The analysis is ...
Gastrointestinal anisakidosis is an under-reported and often misdiagnosed parasitic infection caused by the larvae of a nematode anisakis. The majority of cases are seen in Japan due to the consumption of raw and undercooked seafood; however, the incidence is likely to rise in the United States given ...
Background Spontaneous abortion is the most common adverse pregnancy outcome. We aimed to investigate a possible link between nutrient deficiencies and the risk of spontaneous abortion. Materials and Methods This case-control study included the case group (n=331) experiencing a spontaneous abortion ...
The pollution level of Lake Bafa was investigated by collecting fish samples {Dicentrarchus labrax (sea bass), Liza ramada (mullet) and Anguilla anguilla (eel)}, surface sediment, and core samples. In all these samples, 210Po and 210Pb concentrations were estimated, and total annual dose rates were ...
Aluminum is a neurotoxic metal with known health effects in animals and humans. Glutathione-S-transferase (GST) genes and enzymes play a major role in detoxification of several heavy metals. Besides a direct relationship with oxidative stress; aluminum decreases GST enzyme activities. Using data from ...
This study was to evaluate the association of urine arsenic with predicted 10-year atherosclerotic cardiovascular disease (ASCVD) risk in U.S. adults with hypertension. Cross-sectional analysis was conducted in 1570 hypertensive adults aged 40–79 years in the 2003–2012 National Health and Nutrition ...
Fish is a major source of nutrients critical for brain development during early life. The importance of childhood fish consumption is supported by several studies reporting associations of n-3 polyunsaturated fatty acid (n-3 PUFA) supplementation with better behavior and school performance. However, ...
Human pharmaceuticals present in the environment have the potential to cause adverse effects on non-target organisms. The “read-across hypothesis” stipulates that pharmaceuticals will exhibit similar biological effects across species (e.g. human and fish) if the molecular target has been conserved and ...
