Introduction This study is part the project “Nursing in Borderland – Finnmark 1939–1950” within nursing history that sheds light on nursing and health care during World War II in Finnmark County, Northern Norway. The study focuses on challenges in nursing care that arose during the war because of war ...
The number of submarine pipelines in the North Sea continues to grow and with it comes the need to monitor and service such systems. In most areas of the North Sea, pipeline inspections are required annually by government inspectorates. These twelve-monthly inspections must be capable of determining, ...
Results from two advanced complementary research echosounding systems are examined and discussed The more complex system is a Hydrographic Wide Swath Sweeping Survey Echosounder for shallow and deep water applications (Hydrosweep) for accurate bathymetric surveys and terrain-following navigation The ...
The paper reviews current knowledge of intensity and directionality of bat echolocation signals. Recent studies have revealed that echolocating bats can be much louder than previously believed. Bats previously dubbed “whispering” can emit calls with source levels up to 110 dB SPL at 10 cm and the louder ...
INTRODUCTION Dangerous cargoes lost in the North Sea must e salvaged before they can cause accidents. Lost cargoes must be found using sonar, and then identified with still and video cameras mounted on a remotely operated vehicle (ROV). Finally, the cargoes must be salvaged or neutralized. The practice ...
INTRODUCTION Since the arrival of seamen in the Bight of Benin, continuous survey and sounding of the bars rivers and ports of Nigeria have been carried pt by master mariners, shipping agents, the Royal Navy, oil companies, dredging companies and the Nigerian Ports Authority. The Ports Authority is ...
ABSTRACT This paper discusses some of the problems associated with the design of subsea pipelines for the hydrocarbon industry Concentrating primarily on subsea tiebacks In the North Sea, it looks at those aspects of design which reflect the tensions between operational requirements, installation requirements ...
ABSTRACT The Unmanned, Untethered, Underwater Vehicle MARTIN was launched by Maridan, Denmark in 1995. MARTIN is being instrumented for bathymetry and inspection of offshore installations (pipelines, sea cable). Sea trials are continuing. UUV are expected to become a feasible supplement to ROVs for ...
ABSTRACT The Ross Worm (Sabellaria spinulosa) can, when found in sufficiently high densities, form a biogenic reef attracts other fauna to the same vicinity. Such reef are now protected as an Annex 1 habitat under the European Union Habitats Directive. As a result, companies proposing to lay infrastructure ...
The recent invasion of the red alga Heterosiphonia japonica in the western North Atlantic Ocean has provided a unique opportunity to study invasion dynamics across a biogeographical barrier. Native to the western North Pacific Ocean, initial collections in 2007 and 2009 restricted the western North ...
In systems with several effectors, the results of dose-response (DR) experiments are usually assessed by checking them against two hypotheses: independent action (IA) and concentration addition (CA). Both are useful simplifications, but do not represent the only possible responses, and avoid to a large ...
In response to endoplasmic reticulum (ER) stress, the signaling pathway termed unfolded protein response (UPR) is activated. To investigate the role of UPR in Litopenaeus vannamei immunity, the activating transcription factor 4 (designated as LvATF4) which belonged to a branch of the UPR, the [protein ...
The present study was carried out on the seasonal abundance and diversity of zooplankton in a semi- intensive prawn farm of Bagerhat district from July to December, 2008. Plankton samples were collected by conical shaped monofilament nylon net (Plankton net) and Lugol’s solution was used for preservation. ...
Background There is evidence to support the use of supplementation with long-chain omega-3 polyunsaturated fatty acids (LCn-3PUFA) from oily fish or fish oil for the treatment of various inflammatory diseases such as rheumatoid arthritis. Chronic obstructive pulmonary disease (COPD) is a progressive, ...
Successful adaptation/acclimatization to low temperatures in micro-algae is usually connected with production of specific biotechnologically important compounds. In this study, we evaluated the growth characteristics in a micro-scale mass cultivation of the Antarctic soil green alga Chlorella mirabilis ...
Many pathogenic bacteria use quorum sensing (QS) systems to regulate the expression of virulence genes in a density-dependent manner. In one widespread QS paradigm the enzyme LuxI generates a small diffusible molecule of the acyl-homoserine lactone (AHL) family; high cell densities lead to high AHL ...
For the rapid production of influenza vaccine antigens in unlimited quantities, a transition from conventional egg-based production to cell-based and recombinant systems is required. The need for higher-yield, lower-cost, and faster production processes is critical to provide adequate supplies of influenza ...
Bivalves play vital roles in marine, brackish, freshwater and terrestrial habitats. In recent years, these ecosystems have become affected through anthropogenic activities. The ecological success of marine bivalves is based on the ability to modify their physiological functions in response to environmental ...
Background Strongylocentrotid sea urchins have a long tradition as model organisms for studying many fundamental processes in biology including fertilization, embryology, development and genome regulation but the phylogenetic relationships of the group remain largely unresolved. Although the differing ...
The predatory marine gastropod Dicathais orbita has been the subject of a significant amount of biological and chemical research over the past five decades. Natural products research on D. orbita includes the isolation and identification of brominated indoles and choline esters as precursors of Tyrian ...
