B-52G crew noise exposure study  

NASA Astrophysics Data System (ADS)

The B-52G aircraft produces acoustic environments that are potentially hazardous, interfere with voice communications and may degrade task performance. Numerous reports from aircrew of high noise levels at crew location have been documented for those B-52G aircraft that have been modified with the Offensive Avionics System. To alleviate and minimize the excessive noise exposures of aircrews, a study of the noise problem in the b-52G was deemed necessary. First, in-flight noise measurements were obtained at key personnel locations on a B-52G during a typical training mission. Then, extensive laboratory analyses were conducted on these in-flight noise data. The resulting noise exposure data were evaluated in terms of the various segments of and the total flight profile relative to allowable noise exposures. Finally, recommendations were developed for short term and long term approaches toward potential improvement in the B-52G noise exposure problem.

The effects of aircraft (B-52) overflights on ancient structures  

NASA Astrophysics Data System (ADS)

To simulate combat missions for the American bomber force, the Air Combat Command conducts low altitude training flights along routes throughout the U.S.A. This paper presents the results of an effort to evaluate the effect of these overflights on the many archaeologically significant structures located beneath the training routes. This study has shown that: (1) low overflights can induce measurable vibrations in these ancient structures; (2) the overflight induced motions do not constitute an appreciable threat to the sites; and (3) the observed levels of motion are no greater than those induced by sources in the natural environment. Although these findings are specific to overflights by B-52s, comparison of the low frequency acoustic signature of the B-52 and that of the B-1B overflights should not pose a significantly greater threat to the structures than B-52 overflights.

Specific role of the SR protein splicing factor B52 in cell cycle control in Drosophila.  

PubMed

E2F and retinoblastoma tumor suppressor protein pRB are important regulators of cell proliferation; however, the regulation of these proteins in vivo is not well understood. In Drosophila there are two E2F genes, an activator, de2f1, and a repressor, de2f2. The loss of de2f1 gives rise to the G(1)/S block accompanied by the repression of E2F-dependent transcription. These defects can be suppressed by mutation of de2f2. In this work, we show that the de2f1 mutant phenotype is rescued by the loss of the pre-mRNA splicing factor SR protein B52. Mutations in B52 restore S phase in clones of de2f1 mutant cells and phenocopy the loss of the de2f2 function. B52 acts upstream of de2f2 and plays a specific role in regulation of de2f2 pre-mRNA splicing. In B52-deficient cells, the level of dE2F2 protein is severely reduced and the expression of dE2F2-dependent genes is deregulated. Reexpression of the intronless copy of dE2F2 in B52-deficient cells restores the dE2F2-mediated repression. These results uncover a previously unrecognized role of the splicing factor in maintaining the G(1)/S block in vivo by specific regulation of the dE2F2 repressor function. PMID:16611989

Eye development under the control of SRp55/B52-mediated alternative splicing of eyeless.  

PubMed

The genetic programs specifying eye development are highly conserved during evolution and involve the vertebrate Pax-6 gene and its Drosophila melanogaster homolog eyeless (ey). Here we report that the SR protein B52/SRp55 controls a novel developmentally regulated splicing event of eyeless that is crucial for eye growth and specification in Drosophila. B52/SRp55 generates two isoforms of eyeless differing by an alternative exon encoding a 60-amino-acid insert at the beginning of the paired domain. The long isoform has impaired ability to trigger formation of ectopic eyes and to bind efficiently Eyeless target DNA sequences in vitro. When over-produced in the eye imaginal disc, this isoform induces a small eye phenotype, whereas the isoform lacking the alternative exon triggers eye over-growth and strong disorganization. Our results suggest that B52/SRp55 splicing activity is used during normal eye development to control eye organogenesis and size through regulation of eyeless alternative splicing. PMID:17327915

Role of HLA-B51 and HLA-B52 in susceptibility to pulmonary tuberculosis.  

PubMed

MHC class I-restricted CD8+ T cells are important for the generation of protective immune responses in MTB infection. CD8+ CTL (cytotoxic T-lymphocyte)-derived IFN-g may be especially important both for cells lacking MHC class II molecules, e.g. in the lung and for macrophages where mycobacteria can evade recognition during chronic infection by sequestering their antigens away from sensitized CD4+ T cells. This study was designed to detect any association of MHC class I (HLA-B) molecules with pulmonary tuberculosis. A total of 75 individuals, comprising of 33 patients with pulmonary tuberculosis; 12 HIV patients who developed tuberculosis and 30 healthy controls, were included in the study. They were typed for HLA-B by the PCR-SSP method. The results of only HLA-B alleles, which are highly significant, are presented here. The number of healthy individuals with HLA-B52 was significantly high when compared to the patient groups (healthy versus TB: 21.2% versus 0.0%, OR=0.0, P<0.0001, P(c)=0.003; healthy versus HIV-TB: 21.2% versus 16.7%; OR=0.74; P<0.001; P(c)=0.003). In contrast, the number of patients, both TB- and HIV-TB-positive, with HLA-B51 was significantly high when compared to the healthy group of individuals (TB versus healthy: 36.7% versus 3%; OR=18.53; P<0.0001; P(c)=0.001; HIV-TB versus healthy: 41.7% versus 3%; OR=22.86; P<0.0001; P(c)=0.001). Only one healthy control was positive to HLA-B51; however this individual also had HLA-B52. The results of this study suggest that HLA-B52(5) has a negative, i.e. a protective association and HLA-B51(5) has a positive (susceptible) association, for pulmonary tuberculosis. Studies on HLA-B51 and HLA-B52 in a larger population to assess their role in tuberculosis may be useful for TB-vaccination strategies, since HLA profiles are likely to be related to vaccine efficacy.

The yield of analyzable material after digestion reached 90% for the material associated to the biofilms, though only 20-30% for that bound to planktonic cells. The polysaccharide(s) in the biofilm had glucuronic and guluronic acids as main components, besides rhamnose, glucose and glucosamine. The proportion of glucuronic to guluronic acid was higher in the polysaccharide(s) found in biofilms formed on stainless steel than in those on glass. PMID:16757156

Takayasu's arteritis is associated with HLA-B*52, but not with HLA-B*51, in Turkey  

PubMed Central

Introduction HLA-B*51 and HLA-B*52 are two close human leukocyte antigen (HLA) allele groups with minor amino acid differences. However, they are associated with two different vasculitides (HLA-B*51 in Behçet's disease and HLA-B*52 in Takayasu's arteritis (TAK)) and with major clinical and immunological differences. In this study, we aimed to screen a large cohort of TAK patients from Turkey for the presence of HLA-B*51 and HLA-B*52 as susceptibility and severity factors. Methods TAK patients (n = 330) followed at a total of 15 centers were included in the study. The mean age of the patients was 37.8 years, and 86% were women. DNA samples from the patients and healthy controls (HC; n = 210) were isolated, and the presence of HLA-B*51 or HLA-B*52 was screened for by using PCR with sequence-specific primers. Results We found a significant association of HLA-B*52 with TAK (20.9% vs HC = 6.7%, P = 0.000, OR = 3.7, 95% CI = 2.02 to 6.77). The distribution of HLA-B*51 did not differ between TAK patients and HCs (22.7% vs 24.8%, OR = 0.9, 95% CI = 0.60 to 1.34). The presence of HLA-B*52 decreased in late-onset patients (> 40 years of age; 12.0%, P = 0.024, OR = 0.43, 95% CI = 0.20 to 0.91). Patients with angiographic type I disease with limited aortic involvement also had a lower presence of HLA-B*52 compared to those with all other disease subtypes (13.1% vs 26%, P = 0.005, OR = 0.43, 95% CI = 0.23 to 0.78). Conclusions In this study, the previously reported association of TAK with HLA-B*52 in other populations was confirmed in patients from Turkey. The functional relevance of HLA-B*52 in TAK pathogenesis needs to be explored further.

Premotor neurons B51 and B52 in the buccal ganglia of Aplysia californica: synaptic connections, effects on ongoing motor rhythms, and peptide modulation.  

PubMed

1. Two buccal ganglia interneurons, labeled here as B51 and B52, have been identified on the basis of morphological and physiological criteria. 2. These neurons have multipolar cell bodies. B51 extends a major neurite, which arborizes in the neuropil ipsilateral to the soma; extends into the buccal commissure, where it branches profusely; and projects an axon out the radular nerve (n1); other processes emanating from the soma arborize in the adjacent cell body layer. B52 arborizes ipsilateral to its cell body and sends a major process out of the ipsilateral hemiganglion into the sheath that attaches the buccal ganglia to the buccal mass proper. Here the B52 axon projects through a previously undescribed structure, which forms an arch over the buccal commissure that we designate the commissural arch. The extraganglionic B52 axon sends several branches into the connective tissue and then returns to the contralateral hemiganglion, where it again branches. 3. Each neuron exhibits a unique set of physiological properties. B51 frequently produces plateau potentials, which persist and are even enhanced in solutions where Ca2+ is replaced with Co2+. On the other hand, B52 shows a powerful posthyperpolarization rebound that contributes to its burst formation during spontaneous and nerve-elicited cyclic motor output. 4. B51 and B52 display distinctive rhythmic bursting on stimulation of the radular nerve or esophageal nerve. Their burst-firing tended to occur at certain phase relationships with respect to firing in other buccal premotor and motor neurons. 5. When firing frequency is measured as a function of intracellularly injected current, B51 shows a steplike increase in firing with increasing current, whereas B52 firing frequency is continuously graded. 6. B51 and B52 were found to make extensive synaptic connections within the buccal ganglia. B51 exhibited primarily excitatory electrical connections with known premotor and motor neurons, including an electrotonic synapse with its contralateral homologue. 7. In contrast, B52 made bilateral inhibitory synapses with nearly all of the premotor and motor neurons of the ventral motor cluster. Most of these connections appeared to be monosynaptic, producing synaptic potentials with short and fixed latencies that persisted when the ganglia were bathed in solutions containing elevated concentrations of Ca2+ and Mg2+. 8. Other synaptic potentials produced by B52 were more variable in size and latency; these included slow inhibition of the B4 and B5 neurons and excitation of an identifiable neuron that projected out the radular nerve.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:2329360

Routine HLA-B genotyping with PCR-sequence-specific oligonucleotides detects a B*52 variant (B*5206).  

PubMed

A new human leukocyte antigen (HLA)-B allele was found during routine typing of samples for a German unrelated bone marrow donor registry, the "Aktion Knochenmarkspende Bayern". After first interpretation of data of two independent low-resolution sequence-specific oligonucleotide typing tests, a B*51 variant was suggested. Further analysis via sequence-based typing identified the sequence as new B*52 allele. This new allele officially assigned as B*5206 differs from HLA-B*520102 by one nucleotide exchange in exon 2. The mutation is located at nucleotide position 274, at which a cytosine is substituted by a thymine leading to an amino acid change at protein position 67 from serine (TCC) to phenylalanine (TTC).

The SR protein B52/SRp55 is required for DNA topoisomerase I recruitment to chromatin, mRNA release and transcription shutdown.  

PubMed

DNA- and RNA-processing pathways are integrated and interconnected in the eukaryotic nucleus to allow efficient gene expression and to maintain genomic stability. The recruitment of DNA Topoisomerase I (Topo I), an enzyme controlling DNA supercoiling and acting as a specific kinase for the SR-protein family of splicing factors, to highly transcribed loci represents a mechanism by which transcription and processing can be coordinated and genomic instability avoided. Here we show that Drosophila Topo I associates with and phosphorylates the SR protein B52. Surprisingly, expression of a high-affinity binding site for B52 in transgenic flies restricted localization, not only of B52, but also of Topo I to this single transcription site, whereas B52 RNAi knockdown induced mis-localization of Topo I in the nucleolus. Impaired delivery of Topo I to a heat shock gene caused retention of the mRNA at its site of transcription and delayed gene deactivation after heat shock. Our data show that B52 delivers Topo I to RNA polymerase II-active chromatin loci and provide the first evidence that DNA topology and mRNA release can be coordinated to control gene expression.

The SR family proteins B52 and dASF/SF2 modulate development of the Drosophila visual system by regulating specific RNA targets.  

PubMed

Deciphering the role of alternative splicing in developmental processes relies on the identification of key genes whose expression is controlled by splicing regulators throughout the growth of a whole organism. Modulating the expression levels of five SR proteins in the developing eye of Drosophila melanogaster revealed that these splicing factors induce various phenotypic alterations in eye organogenesis and also affect viability. Although the SR proteins dASF/SF2 and B52 caused defects in ommatidia structure, only B52 impaired normal axonal projections of photoreceptors and neurogenesis in visual ganglia. Microarray analyses revealed that many transcripts involved in brain organogenesis have altered splicing profiles upon both loss and gain of B52 function. Conversely, a large proportion of transcripts regulated by dASF/SF2 are involved in eye development. These differential and specific effects of SR proteins indicate that they function to confer accuracy to developmental gene expression programs by facilitating the cell lineage decisions that underline the generation of tissue identities.

[Psychopathology service on ships].  

PubMed

The aim of this study was to describe the specific engineering services and suitability of candidates for the psychophysical performance. Navy ships are equipped with equipment and weapons are controlled by electronic devices ship and crew. Advanced technology puts high demands on operator. For the ship's staff are recruited soldiers of the psychophysical characteristics predisposing to this kind of action. The paper uses personal experience to work in military units of the Navy, and data from the literature. Terms of sailing ships off the summer season are defined as difficult. The crew during a combat mission felt the risks associated with movements of the ship in difficult meteorological conditions, and associated with the implementation of the task. The development of ship's technical equipment, working in isolated groups, functioning within a limited space, noise, vibration, electromagnetic waves heighten the emotional burden on crew members. Military service on Navy ships require high psycho-physical predisposition, resistance to stress. The crucial factor is proper selection among the candidates based on psychiatric and psychological counseling for military and medical jurisprudence. Also plays a significant role for training doctors and specialists in psychoprophylaxy of military units in the field of mental hygiene. PMID:20642117

Metacenter and ship stability

We address the location of the metacenter M of a floating body such as a ship. Previous studies of M in relation to the stability of a ship have mainly used geometrical approaches and were limited to near equilibrium. We develop a quantitative approach to the location of M for a general shape of the cross-section of a floating body in a rolling/pitching motion and for an arbitrary heel angle. We show that different definitions of M refer to one and the same special point of the floating body. We discuss the relation between the height of M with respect to the line of flotation and the contribution of the buoyancy force to ship stability. We provide expressions and graphs of the buoyancy, flotation, and metacentric curves for some simple shapes of floating bodies.

Ship propulsion system  

SciTech Connect

This patent describes an improved efficiency propulsion system for a ship operated at both deep and shallow water depths, and at variable loaded and ballast waterlines. This propulsion system consists of a number of elements interactive in their operation. The first component of the system detailed is a variable diameter propeller means equipped with a mechanism for varying the diameter of the propeller between a maximum extended diameter and a minimum diameter. The next component of the system depicted in the patent is a propeller shaft mounting which enables the propeller to rotate in the stern portion of the ship. The propeller shaft is characterized as extending parallel to the bottom keel of the ship and having an axis of rotation displaced from the bottom keel a distance less than one-half the maximum diameter of the propeller means but more than one-half of the minimum diameter of the propeller means. As a consequence of the systems design characteristics the ship may obtain maximum propeller efficiency by means of the extension in diameter of the propeller means when it is operated in a fully loaded condition in deep water.

Can bubbles sink ships?  

NASA Astrophysics Data System (ADS)

I investigate the interplay between the buoyancy force and the upwelling (or drag) force which act on a floating object when bubbles are rising through a body of water. Bubbles reduce the buoyant force by reducing the density of the water, but if they entrain an upwelling flow of water as they rise, they can produce a large upward drag force on the floating object. In an upwelling flow, our model ship (density=0.94 g/cm3) floats in a foam whose density is only 0.75 g/cm3. Comparing results with and without upwelling currents is an interesting demonstration and has real-world applications to ships in the ocean.

Analysis of a ship-to-ship collision  

SciTech Connect

Sandia National Laboratories is involved in a safety assessment for the shipment of radioactive material by sea. One part of this study is investigation of the consequences of ship-to-ship collisions. This paper describes two sets of finite element analyses performed to assess the structural response of a small freighter and the loading imparted to radioactive material (RAM) packages during several postulated collision scenarios with another ship. The first series of analyses was performed to evaluate the amount of penetration of the freighter hull by a striking ship of various masses and initial velocities. Although these analyses included a representation of a single RAM package, the package was not impacted during the collision so forces on the package could not be computed. Therefore, a second series of analyses incorporating a representation of a row of seven packages was performed to ensure direct package impact by the striking ship. Average forces on a package were evaluated for several initial velocities and masses of the striking ship. In addition to. providing insight to ship and package response during a few postulated ship collisions scenarios, these analyses will be used to benchmark simpler ship collision models used in probabilistic risk assessment analyses.

Remote sensing measurements showed a coupling of ship plume dynamics and entrainment into overlaying clouds. Morphological and dynamic effects were observed on clouds unique to the ship tracks. These morphological changes included lower cloud bases early in the ship-track formation, evidence of raised cloud bases in more mature tracks, sometimes higher cloud tops, thin cloud-free regions paralleling the tracks, and often stronger radar returns. The ship-based lidar aerosol measurements revealed that ship plumes often interacted with the overlying clouds in an intermittent rather than continuous manner. These observations imply that more must be learned about ship-track dynamics before simple relations between cloud condensation nuclei and cloud brightness can be developed.

Operational options for green ships  

NASA Astrophysics Data System (ADS)

Environmental issues and rising fuel prices necessitate better energy-efficiency in all sectors. The shipping industry is one of the major stakeholders, responsible for 3% of global CO2 emissions, 14%-15% of global NO X emissions, and 16% of global SO X emissions. In addition, continuously rising fuel prices are also an incentive to focus on new ways for better energy-effectiveness. The green ship concept requires exploring and implementing technology on ships to increase energy-efficiency and reduce emissions. Ship operation is an important topic with large potential to increase cost-and-energy-effectiveness. This paper provided a comprehensive review of basic concepts, principles, and potential of operational options for green ships. The key challenges pertaining to ship crew i.e. academic qualifications prior to induction, in-service training and motivation were discussed. The author also deliberated on remedies to these challenges.

Suicidal mothers  

PubMed Central

Abstract: Background: Epidemiological research has demonstrated that suicidal ideation is a relatively frequent complication of pregnancy in both developed and developing countries. Hence, the aims of this study are: to assess whether or not pregnancy may be considered a period highly susceptible to suicidal acts; to recognize potential contributing factors to suicidal behaviors; to describe the repercussions of suicide attempts on maternal, fetal, and neonatal outcome; to identify a typical profile of women at high risk of suicide during pregnancy. Methods: Medical literature information published in any language since 1950 was identified using MEDLINE/PubMed, Scopus, and Google Scholar databases. Search terms were: "pregnancy", (antenatal) "depression", "suicide". Searches were last updated on 28 September 2010. Forty-six articles assessing the suicidal risk during pregnancy and obstetrical outcome of pregnancies complicated by suicide attempts were analyzed, without methodological limitations. Results: Worldwide, frequency of suicidal attempts and the rate of death by suicidal acts are low. Although this clinical event is rare, the consequences of a suicidal attempt are medically and psychologically devastating for the mother-infant pair. We also found that common behaviors exist in women at high risk for suicide during pregnancy. Review data indeed suggest that a characteristic profile can prenatally identify those at highest risk for gestational suicide attempts. Conclusions: Social and health organizations should make all possible efforts to identify women at high suicidal risk, in order to establish specific programs to prevent this tragic event. The available data informs health policy makers with a typical profile to screen women at high risk of suicide during pregnancy. Those women who have a current or past history of psychiatric disorders, are young, unmarried, unemployed, have incurred an unplanned pregnancy (eventually terminated with an induced abortion), are addicted to illicit drugs and/or alcohol, lack effective psychosocial support, have suffered from episodes of sexual or physical violence are particularly vulnerable.

Genetic relationships between resistance to stalk-tunneling by the European corn borer and cell-wall components in maize population B73xB52.  

PubMed

The objective of this study was to assess the relationships among quantitative trait loci (QTL) detected for European corn borer (ECB) tunneling and cell-wall components (CWC) neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL) content in leaf-sheath and stalk tissues in a maize recombinant inbred line population derived from inbred lines B73 and B52. Most of the QTL for ECB resistance (10/13) were at QTL positions for one or more CWC. Of the 12 QTL for NDF and ADF in leaf-sheaths, five for each trait were at or near QTL for ECB tunneling. Four of these five QTL for NDF and ADF mapped to common locations. Four of the eight leaf-sheath ADL QTL were detected in the same genomic regions as ECB QTL. For stalk tissue, four regions contained common/overlapping QTL for ECB tunneling, NDF, and ADF. Six such regions were observed for stalk ADL and ECB tunneling. Seven of the ten QTL associated with both CWC and ECB tunneling contributed to the negative correlations observed between these traits, while relatively few QTL effects were positively correlated. This suggests that while CWC contribute to ECB resistance in this population, other mechanisms and other genes also are involved. Several QTL contributing to the negative correlations between ECB tunneling and CWC in the leaf-sheaths mapped to similar positions as QTL detected in tropical maize populations for resistance to leaf-feeding by Diatraea grandiosella Dyar and Diatraea saccharalis Fabricus. These regions may contain genes involved in the synthesis of cellulose, hemicellulose, and lignin in the leaf-blades and leaf-sheaths of maize. PMID:15887040

Ship Creek bioassessment investigations  

SciTech Connect

Pacific Northwest Laboratory (PNL) was asked by Elmendorf Air Force Base (EAFB) personnel to conduct a series of collections of macroinvertebrates and sediments from Ship Creek to (1) establish baseline data on these populations for reference in evaluating possible impacts from Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) activities at two operable units, (2) compare current population indices with those found by previous investigations in Ship Creek, and (3) determine baseline levels of concentrations of any contaminants in the sediments associated with the macroinvertebrates. A specific suite of indices established by the US Environmental Protection Agency (EPA) was requested for the macroinvertebrate analyses; these follow the Rapid Bioassessment Protocol developed by Plafkin et al. (1989) and will be described. Sediment sample analyses included a Microtox bioassay and chemical analysis for contaminants of concern. These analyses included, volatile organic compounds, total gasoline and diesel hydrocarbons (EPA method 8015, CA modified), total organic carbon, and an inductive-coupled plasma/mass spectrometry (ICP/MS) metals scan. Appendix A reports on the sediment analyses. The Work Plan is attached as Appendix B.

Ship hull bottom slamming  

SciTech Connect

A method is presented to evaluate the hull bending moment due to bottom slamming. Theoretical explanations and updates are given to the commonly used empirical results, and some observations are made on slamming. An energy approach combined with a strip theory is used to get the hydrodynamic load, and to analyze the effects of the forward velocity. Impacts of simple bodies are simulated numerically to describe these loads. The ship hull is represented as a nonuniform free-free beam, and its response is decomposed into normal modes; only the contribution of the first one is kept. In a numerical example, the bending moment during the impact is determined. It is shown that its value when the impact is over is much harder to predict. The maximum value of the bending moment, however, occurs during the impact, and is an increasing function of the vertical velocity, as expected. A simple expression is given for it.

Contemporary impingements on mothering.  

PubMed

Mothering in contemporary Western society needs to be understood in the context of a rapidly changing social context. Increased geographic mobility, improved access to child-related information through the media, and scientific and technological progress have contributed to significant shifts in cultural views on mothering. Several contextual impingements on mothering, including changing family structure, economic pressures, decreased social support, cultural ideals of the perfect mother, and increased awareness of interpersonal and global trauma impact mothers' internal worlds. These societal changes often reinforce mothers' fear of losing their children and an idealization of intensive mothering, and evoke challenges in reorganizing their sense of personal identity. Implications for psychoanalytic theory and practice, and specifically the need to integrate individual and contextual forces related to experiences of mothers will be explored. PMID:19295618

Regulation of the aprX-lipA operon of Pseudomonas fluorescens B52: differential regulation of the proximal and distal genes, encoding protease and lipase, by ompR-envZ.  

PubMed

The production of lipase and protease from psychrotrophic strains of Pseudomonas fluorescens may result in spoilage of dairy products. The lipase (lipA) and alkaline metalloprotease (aprX) genes of P. fluorescens B52 are regulated by temperature and are located at opposite ends of an operon which contains eight genes and spans 14 kb. In this report, we show that lipase activity in the supernatant of cultures of P. fluorescens strain B52 is also regulated by the homologue of the Escherichia coli EnvZ-OmpR two-component regulatory system. Differences in the regulation of lipase and protease may be related to the proximal and distal locations of aprX and lipA within the operon. PMID:15598539

Understanding the capabilities of satellite sensors with spatial and spectral characteristics similar to those of MODIS for Maritime Domain Awareness (MDA) is of importance because of the upcoming NPOES with 100 minutes revisit time carrying the MODIS-like VIIRS multispectral imaging sensor. This paper presents an experimental study of ship detection using MODIS imagery. We study the use of ship signatures such as contaminant plumes in clouds and the spectral contrast between the ship and the sea background for detection. Results show the potential and challenges for such approach in MDA.

Identification of a CTL-directed epitope encoded by an intron of the putative tumor suppressor gene Testin of the common fragile site 7G region: a peptide vaccine candidate for HLA-B52+ and HLA-62+ cancer patients.  

PubMed

Although cytotoxic T lymphocyte (CTL)-directed epitopes binding to human histocompatibility leukocyte antigen (HLA)-A molecules have been well characterized, those binding to HLA-B molecules have not, largely due to their large diversity. In this study we report a unique cancer antigen gene, tentatively named Testin-related gene (TRG), which encodes CTL-directed epitopes on the HLA-B52 molecules most frequently expressed in Asians. TRG is located in an intron of the putative tumor suppressor gene Testin in the common fragile site 7G region at 7q31.2. TRG mRNA was expressed in the majority of cancer cells and cancer tissue tested, whereas it was scarcely expressed in the majority of normal tissues, and only low-level expression of TRG was detected in the heart, liver, and pancreas. One TRG peptide had the ability to induce HLA-B52-restricted CTL cytotoxic to TRG+ tumor cells in peripheral blood mononuclear cells (PBMC) of epithelial cancer patients. This peptide also induced HLA-B62-restricted and tumor-reactive CTL in PBMC of cancer patients. Therefore, this TRG-derived peptide might be appropriate for use in peptide-based immunotherapy for relatively large numbers of cancer patients throughout the world, given that 34% of Japanese, 27% of Chinese, and 13% of Caucasians express either HLA-B52 or HLA-B62 molecules PMID:14579264

Black Ships & Samurai  

NSDL National Science Digital Library

In the early days of July 1853, the residents of Uraga on the outskirts of the feudal capital of Japan at Edo were privy to a rather unusual sight: Four hulking foreign warships had entered their harbor under the power of coal, and under the command of Commodore Matthew Perry of the United States. So began one of the pivotal cultural interactions between East and West. Commodore Perry came as an emissary of the United States in order to create a formal relationship with the empire of Japan. Developed by Professors John W. Dower and Shigeru Miyagawa from MIT, this site brings together a wealth of rarely seen graphics from both sides of this historic encounter, and original textual commentaries by Professor Dower. The Core Exhibit area contains the bulk of these amazing visual materials, including those renderings of the initial encounters of the two cultures in the years 1853 and 1854 and some revealing portraits of both Japanese officials and Commodore Perry himself. Visitors should not leave the site without viewing at least part of the interactive recreation of the 30-foot-long Japanese Black Ship Scroll, which was painted in 1854. The scroll features a number of scenes documenting these encounters, and also includes explanatory text as well.

Ship infrared detection/vulnerability  

NASA Astrophysics Data System (ADS)

The IR contrast of ships at sea is of importance for those who want to detect or identify the ship and for those who worry about this. This IR contrast is determined by a large number of parameters. Of course temperatures of the ship's structure and those of the ambient sea and air are important, but also important are the reflection properties of the sea background and the radiance distribution of the surrounding sky. Modeling of these phenomena appears to be very complicated and the accuracy of the results is rather course in many cases. Therefore, at FEL- TNO an approach has been followed, using a package of sensors on board the ship, giving radiometric or real temperature data of specific surface elements and background radiometric data. These data are taken into a PC system, providing radiant contrast data in any IR-spectral band. Taking into account atmospheric propagation effects and sensor performance, a simplified detection model provides range data in the form of polar diagrams with elevation as parameter. The commander of the ship uses the system as an IR Tactical Decision Aid (TDA), as he may decide upon countermeasures, if the vulnerability of his ship exceeds certain limits.

Cloud Condensation Nuclei and Ship Tracks.  

NASA Astrophysics Data System (ADS)

Enhancements of droplet concentrations in clouds affected by four ships were fairly accurately predicted from ship emission factors and plume and background cloud condensation nucleus (CCN) spectra. Ship exhausts thus accounted for the increased droplet concentrations in these `ship tracks.' Derived supersaturations were typical of marine stratus clouds, although there was evidence of some lowering of supersaturations in some ship tracks closer to the ships where CCN and droplet concentrations were very high.Systematic differences were measured in the emission rates of CCN for different engines and fuels. Diesel engines burning low-grade marine fuel oil produced order of magnitude higher CCN emissions than turbine engines burning higher-grade fuel. Consequently, diesel ships burning low-grade fuel were responsible for nearly all of the observed ship track clouds. There is some evidence that fuel type is a better predictor of ship track potential than engine type.

SEA modelling of ship structures  

NASA Astrophysics Data System (ADS)

Statistical Energy Analysis (SEA) has been used to get analytical estimates, as an alternative method to the empirical one, of the the transmission losses of structure-borne noise along the ship hull, which is one of the most important procedures in predicting cabin noise. Major members such as decks, shell plates, and bulkheads were modeled as subsystems representing flexural and/or in-plane wave groups. The modeling process was relatively simple because only structural members of a cross section were considered. However, when one wishes to obtain more theroetical predictions by using SEA, modeling must include a much larger number of subsystems including air spaces, which is no longer simple, even for the aft-part of a ship. The ship structures are so complicated that it is a difficult job to define subsystems themselves. And the number of subsystems in general is so large that preparing the input data will require enormous efforts. More importantly, numerous empirical factors accumulated in past experience and on-board measurements should be appropriately considered in the SEA modeling. Moreover, taking every detail of the multi-connected structures as subsystems does not necessarily yield more accurate results. In this paper, we discuss various aspects of the SEA modeling of the ship. In particular, we are concerned with the simplifying of complex structures and inclusion of the empirical factors. We suggest some practical techniques, which might be useful in noise analysis of commercial ships.

These findings have important consequences for ocean chemistry, since the sulfuric and nitric acids formed are strong acids in contrast to the weak carbonic acid formed by dissolution of CO2. Our results also provide background for discussion of expanded controls to mitigate acidification due to these shipping emissions.

Wellbeing of new mothers.  

PubMed

This paper reports indicators of wellbeing and early parenting stress in a representative sample of first-time mothers in north-east England. A total of 185 mothers were recruited in the antenatal period to a controlled trial of an early parenting intervention. They were interviewed at home when the baby was aged around one month, and completed the General Health Questionnaire (GHQ12) and the Parenting Daily Hassles Scale. Almost half of mothers reported psychological distress above the accepted GHQ12 cut-off point. However, distress was not related to variables such as low socio-economic status, as had been predicted. Early parenting stress was greater in relatively more educated and older mothers. New motherhood is likely to be stressful, even where mothers do not have postpartum depression, and so a range of supports is required. PMID:18416404

Underwater radiated noise from modern commercial ships.  

PubMed

Underwater radiated noise measurements for seven types of modern commercial ships during normal operating conditions are presented. Calibrated acoustic data (<1000 Hz) from an autonomous seafloor-mounted acoustic recorder were combined with ship passage information from the Automatic Identification System. This approach allowed for detailed measurements (i.e., source level, sound exposure level, and transmission range) on ships of opportunity. A key result was different acoustic levels and spectral shapes observed from different ship-types. A 54 kGT container ship had the highest broadband source level at 188 dB re 1 ?Pa@1m; a 26 kGT chemical tanker had the lowest at 177 dB re 1 ?Pa@1m. Bulk carriers had higher source levels near 100 Hz, while container ship and tanker noise was predominantly below 40 Hz. Simple models to predict source levels of modern merchant ships as a group from particular ship characteristics (e.g., length, gross tonnage, and speed) were not possible given individual ship-type differences. Furthermore, ship noise was observed to radiate asymmetrically. Stern aspect noise levels are 5 to 10 dB higher than bow aspect noise levels. Collectively, these results emphasize the importance of including modern ship-types in quantifying shipping noise for predictive models of global, regional, and local marine environments.

Predicting ship fuel consumption: Update. Technical report  

SciTech Connect

This report is concerned with the prediction of ship propulsion fuel consumption as a function of ship speed for U.S. Navy combatant and auxiliary ships. Prediction is based on fitting an analytic function to published ship class speed-fuel use data using nonlinear regression. The form of the analytic function fitted is motivated by the literature on ship powering and resistance. The report discusses data sources and data issues, and the impact of ship propulsion plant configuration on fuel use. The regression coefficients of the exponential function fitted, tabular numerical comparison of predicted and actual fuel use data, the standard error of the estimate, and plots of actual and fitted data are given for 22 classes of Navy ships.

Primitive Analysis of the Ship Tracking Problem.  

NASA Astrophysics Data System (ADS)

Satellite images reveal tracks of enhanced solar reflectivity in low-level stratus clouds over the ocean that are known to be produced by the aerosols emitted from diesel-powered ships. The question arises: Can we track a ship from such images? A primitive model of convection-diffusion of particles from the moving ship to the condensation level, and of formation of the detectable ship track, is developed. The analysis takes account of various influences, such as ship and wind velocity vectors. It yields, inter alia, the dimensions of the ship track and its disposition relative to the ship. Plausible parameter values give results in the observed range. Tracking is achieved for the simplified problem, but a paucity of meteorological and other data causes practical difficulties.

Relationship between container ship underwater noise levels and ship design, operational and oceanographic conditions  

PubMed Central

Low-frequency ocean ambient noise is dominated by noise from commercial ships, yet understanding how individual ships contribute deserves further investigation. This study develops and evaluates statistical models of container ship noise in relation to design characteristics, operational conditions, and oceanographic settings. Five-hundred ship passages and nineteen covariates were used to build generalized additive models. Opportunistic acoustic measurements of ships transiting offshore California were collected using seafloor acoustic recorders. A 5–10?dB range in broadband source level was found for ships depending on the transit conditions. For a ship recorded multiple times traveling at different speeds, cumulative noise was lowest at 8?knots, 65% reduction in operational speed. Models with highest predictive power, in order of selection, included ship speed, size, and time of year. Uncertainty in source depth and propagation affected model fit. These results provide insight on the conditions that produce higher levels of underwater noise from container ships.

Optical Influence of Ship Wakes  

NASA Astrophysics Data System (ADS)

The optical variations observed within ship wakes are largely due to the generation of copious amounts of air bubbles in the upper ocean, a fraction of which accumulate as foam at the surface, where they release scavenged surfactants. Field experiments were conducted to test previous theoretical predictions of the variations in optical properties that result from bubble injection in the surface ocean. Variations in remote-sensing reflectance and size distribution of bubbles within the ship-wake zone were determined in three different optical water types: the clear equatorial Pacific Ocean, moderately turbid coastal waters, and very turbid coastal waters, the latter two of which were offshore of New Jersey. Bubbles introduced by moving vessels increased the backscattering in all cases, which in turn enhanced the reflectance over the entire visible and infrared wave bands. The elevated reflectance had different spectral characteristics in the three locations. The color of ship wakes appears greener in the open ocean, whereas little change in color was observed in near-coastal turbid waters, consistent with predictions. Colorless themselves, bubbles increase the reflected radiance and change the color of the ocean in a way that depends on the spectral backscattering and absorption of the undisturbed background waters. For remote observation from aircraft or satellite, the foam and added surfactants further enhance the reflectance to a degree dependent on the illumination and the viewing geometry.

First Results from SHIP Experiment  

SciTech Connect

At present, the GDT facility is being upgraded. The first stage of the upgrade is the Synthesised Hot Ion Plasmoid (SHIP) experiment. It aims, on the one hand, at the investigation of plasmas which are expected to appear in the region of high neutron production in a GDT based fusion neutron source proposed by the Budker Institute and, on the other hand, at the investigation of plasmas the parameters of which have never been achieved before in axisymmetric magnetic mirrors.The experiment is performed in a small mirror section which is installed at the end of one side of GDT. The magnetic field on axis is in the range of 0.5-2.0 Tesla and the mirror ratio is 1.2-1.4. The mirror is filled with background plasma streaming in from the central cell. This plasma component is maxwellised and has an electron temperature of about 100 eV. Two neutral beam injectors perpendicularly inject a total current of about 50 Atom Amperes of deuterium neutrals with an energy of 20 keV as a pulse with a duration of about 1 ms. Ionisation of the beams generates the high-energy ion component. The device has been equipped with several diagnostic methods which are successfully used in GDT experiments.The paper presents first results of plasma parameter measurements in SHIP experiment.

Couples Relationships of AFDC Mothers  

Microsoft Academic Search

Virtually nothing is known about AFDC mothers and their relationships with their male friends. Yet such men are clearly an influence in their lives. Findings from a sample of 275 Baltimore AFDC mothers provide important exploratory data about the characteristics of these relationships and about how women who have a long-term male friend differ from AFDC mothers who do not.

Ship detection based on spatial partial features  

NASA Astrophysics Data System (ADS)

This paper mainly studies how to detect a wide variety of ships from the ship-borne infrared images in order to implement sea monitoring. Different types of ships have significant differences in their appearance. The traditional detection method which uses the global texture features of the object is not suitable to detect varied ships. This paper presents a novel detection algorithm which extracts spatial partial texture features trained by Adaboost to establish the ship model for detection. We first extract all the partial regions of the object through random traversal, and then extract the texture features by using the "Uniform LBP" operator. Compared to the traditional way, we save each partial feature individually as one feature vector, which not only reduces the vector dimension but also highlights the key regions when the partial regions with strong generality are selected by Adaboost at the second step. Finally, the selected partial features are boosted with weights to establish ship model for the ship detection. The proposed approach is efficient and robust in the infrared ship detection.

Mice Acquire Flavor Preferences During Shipping  

PubMed Central

Vigorous motion can cause rodents to develop flavor aversions and show other signs of malaise. We tested whether a flavor aversion could be induced by shipping mice from an animal breeder to a test site. Boxes of 12 male C57BL/6J mice were shipped ~950 km from Bar Harbor, ME to Philadelphia, PA by truck. For some boxes, the gel provided for hydration was flavored with almond and for others it was flavored with banana. After the journey, the mice were individually housed and allowed to recover for 5 days. They then received a choice between the two flavors of gel. Contrary to expectations, mice preferred the flavor they had previously ingested during shipping. Controls given flavored gel under similar conditions but while stationary did not show a preference. These results suggest that mice find shipping or its sequelae pleasurable. If mice are travel sick this must be inconsequential relative to other components of the shipping experience.

Ship candidates extraction for optical color imagery  

NASA Astrophysics Data System (ADS)

Ship detection is of great significance lowing to its wide applications. In most existing approaches, some predetection methods are often used to extract ship candidates since applying an accurate algorithm throughout the whole image will be time-consuming and could even cause a lot of false alarms. In addition, most related work focuses on panchromatic imagery but only a little attention has been paid to color imagery. Color images contain more discriminative information of ships than panchromatic images, so it will be easier to extract ships in color images. Further, more information also means more potential to implement image enhancement techniques to solve the problem caused by poor illumination, which is very common in optical images. In this paper, with respect to optical color imagery, we propose a new predetection approach to extract ship candidates preliminarily and rapidly using color information. Firstly, an image enhancement algorithm is employed to improve the quality of input images. Then, we regard the color image as a hyperspectral image and extract ship candidates using a hyperspectral algorithm based on spectral signature model. This hyperspectral algorithm, in essence, utilizes the color information of ships, but the color information is processed in a hyperspectral manner. Unlike the commonly used color segment algorithms which focus on the thresholds in color space, this hyperspectral algorithm concerns more on the patterns of color vectors. Experimental results on real dataset indicate that this image enhancement algorithm is quite suitable for remote sensing images and its performance is better than histogram equalization based techniques. In addition, the hyperspectral algorithm also shows good performance in extracting ship candidates in color images, especially for small ships.

The two activities at this site allow students to conduct hands-on experiments exploring the basic principles of why ships float, and to build simple models which show how special tools on deck, using levers and pulleys, allow researchers and crew to handle heavy equipment and sample water layers deep in the ocean. In the first activity students will conduct experiments demonstrating the effects of varying rates of salinity on how high out of the water a simple "ship" will float. In the second part students will investigate how simple machines help move large loads on a ship.

SHIP: the Seafarers Health Improvement Program.  

PubMed

The Seafarers Health Improvement Program (SHIP) was initiated in 1978 by the United States Public Health Service to improve the health status of seafarers, their health environment, medical care and safety aboard ship, and communication between parties responsible for the health and safety of American seafarers. The program is a collaborative effort of representatives of the maritime industry, physicians, and concerned governmental agencies. Principal achievements of SHIP include establishment of Entry Level Standards and Retention Guidelines for seafarers, development of the Seafarer Emergency Medical Training Program, and initiation of a program making medical records available on board.

Study of SHE at SHIP  

SciTech Connect

The nuclear shell model predicts that the next doubly magic shell-closure beyond {sup 208}Pb is at a proton number Z = 114, 120, or 126 and at a neutron number N = 184. The outstanding aim of experimental investigations is the exploration of this region of spherical 'SuperHeavy Elements'(SHEs). Experimental methods are described, which allowed for the identification of elements produced on a cross-section level of about 1 pb. Reactions used at SHIP are based on targets of lead and uranium. The decay data reveal that for the heaviest elements, the dominant decay mode is alpha emission, not fission. Decay properties as well as reaction cross-sections are compared with results obtained at other laboratories and with results of theoretical investigations. Finally, plans are presented for the further development of the experimental set-up and the application of new techniques, as for instance the precise mass measurement of the produced nuclei using ion traps. At increased sensitivity, detailed exploration of the region of spherical SHEs will start, after first steps on the island of SHEs were made in recent years.

Papers of Ship Research Institute  

NASA Astrophysics Data System (ADS)

This issue contains a report that summarizes the work to date on the removal of the boundary layer on a flat plate for use with Wing In Surface Effect Ship (WISES) model testing. A simple practical method is described which involves the use of a contraction and slot in order to suck the boundary layer from the plate. Theoretical aspects of the design are discussed with relation to the level of suction and the slot width. The boundary layer height was obtained through measurement of the mean velocity profile and a reduction of 50 percent was generally observed when suction was used. The effects on the forces on a low aspect-ratio wing were used to verify the technique for wing heights above 2.5 percent of the mean chord. Below this height separation of the boundary layer on the ground plate is thought to have altered the pressure distribution on the wing. The report is followed by technical memorandum on a new pulsating wind tunnel with a water tank.

Shipping Anomaly from NMIS Imaging  

SciTech Connect

In 2007, a shipping container that arrived at ORNL was imaged using the neutron and gamma ray imaging capability of Nuclear Materials Identification System (NMIS). NMIS with imaging uses a time-tagged radiation source, which can be either a DT neutron generator or a 252Cf spontaneous fission source. The initial imaging measurements used the DT generator s 14.1 MeV neutrons. Because of the low attenuation of the container and its contents, subsequent measurements were performed with the fission energy spectrum neutrons and gamma rays of the 252Cf source. The 252Cf source provides a simultaneous measurement of both a neutron (more sensitive to organics) and a gamma ray (more sensitive to steels) image to be obtained. The images showed that the container contents were partially inverted instead of their expected arrangement. This information was useful in assessing the shipment packaging before the container was opened and indicates how NMIS with imaging can be used to image receipts.

Ship dynamics for maritime ISAR imaging.  

SciTech Connect

Demand is increasing for imaging ships at sea. Conventional SAR fails because the ships are usually in motion, both with a forward velocity, and other linear and angular motions that accompany sea travel. Because the target itself is moving, this becomes an Inverse- SAR, or ISAR problem. Developing useful ISAR techniques and algorithms is considerably aided by first understanding the nature and characteristics of ship motion. Consequently, a brief study of some principles of naval architecture sheds useful light on this problem. We attempt to do so here. Ship motions are analyzed for their impact on range-Doppler imaging using Inverse Synthetic Aperture Radar (ISAR). A framework for analysis is developed, and limitations of simple ISAR systems are discussed.

Reversing mother's curse revisited.  

PubMed

Because of maternal mtDNA inheritance, mtDNA mutations detrimental only in males are not expected to be selected against, an effect termed the "mother's curse." However, if there is positive-assortative mating, equivalent to what was called "inbreeding" by Wade and Brandvain (2009), then selection can act to reduce the frequency of these male-specific detrimental mtDNA mutants. On the other hand, as shown here negative-assortative mating, or "outbreeding, " paradoxically can result in an increase in the frequency of male-specific detrimental mtDNA mutants. The implications of these findings are briefly discussed. PMID:22276553

Estimation Of The Average Velocity Of Ship(s) Using Multi Sensor Data  

NASA Astrophysics Data System (ADS)

IRS_P4 (OCM) and NOAA-AVHRR are ocean sensors. These sensors have variety of applications besides being used for retrieval of ocean parameters like chlorophyll, suspended matter, dissolved organic matter Sea surface temperature (SST) and Identification of Potential Fishing Zones (PFZ). Apart from this an attempt has been made to track the ship(s) and estimated its velocity. It is important to keep the track of the ship movement and velocity for surveillance of oil tankers and large vessels, ply in the shipping routes for possible assessment of oil spill and defense applications. The ships while moving uses fossil fuel and release their exhaust in the form of Sulfur dioxide (SO2) gas. This Sulfur dioxide when comes in contact with water vapour, leads to the formation of Sulfate Aerosol's. These aerosol's act as the nuclei or 'seeds', these nuclei are called as cloud condensation nuclei (CCN), around which cloud droplets take shape and together these droplets form clouds. Narrow lines of perturbed regions in marine stratiform clouds, caused by moving ships, appear brighter in satellite imagery. They can also appear as narrow lines of clouds in an otherwise cloud-free sky. Ship tracks are the long lived cloud lines that are formed from ship exhaust. The track of large ships is sometimes visualized as a trail, known as ship track. These are typically very long even 500km sometimes, i.e. long enough to be seen in Satellite imagery. These tracks formed in marine boundary layers that were between 300 to 750m height, high relative humidity, small Air-Sea temperature difference (0.5°C), moderate winds (average of 7 m/s) (Durkee et.al 2000).These tracks directly scattering solar radiation back to space and increasing cloud reflectivity through increased droplet concentrations, these clouds reflect much more solar energy than the ocean surface. In Infra red (IR) region the reflectance of the cloud is more compared with visual Bands, and thus we get ship track information from IR of OCM (865 nm) and 3.7 ?m of AVHRR Bands. Different sensors covering the regional seas at different time on a given day provide the relative displacement of ship with in a known time interval. By recording the time lag between the relative positions of a ship by mapping its tracks; its possible estimates the velocity of the ship which is in motion. There fore the satellite data is found to be most ideal tracking system of ships. Using above principle an attempt is made to identify different ships during the observations on 16 Mar 2002 in Arabian Sea.

Structural health monitoring for ship structures  

SciTech Connect

Currently the Office of Naval Research is supporting the development of structural health monitoring (SHM) technology for U.S. Navy ship structures. This application is particularly challenging because of the physical size of these structures, the widely varying and often extreme operational and environmental conditions associated with these ships missions, lack of data from known damage conditions, limited sensing that was not designed specifically for SHM, and the management of the vast amounts of data that can be collected during a mission. This paper will first define a statistical pattern recognition paradigm for SHM by describing the four steps of (1) Operational Evaluation, (2) Data Acquisition, (3) Feature Extraction, and (4) Statistical Classification of Features as they apply to ship structures. Note that inherent in the last three steps of this process are additional tasks of data cleansing, compression, normalization and fusion. The presentation will discuss ship structure SHM challenges in the context of applying various SHM approaches to sea trials data measured on an aluminum multi-hull high-speed ship, the HSV-2 Swift. To conclude, the paper will discuss several outstanding issues that need to be addressed before SHM can make the transition from a research topic to actual field applications on ship structures and suggest approaches for addressing these issues.

Speckle noise reduction in SAR images ship detection  

NASA Astrophysics Data System (ADS)

At present, there are two types of method to detect ships in SAR images. One is a direct detection type, detecting ships directly. The other is an indirect detection type. That is, it firstly detects ship wakes, and then seeks ships around wakes. The two types all effect by speckle noise. In order to improve the accuracy of ship detection and get accurate ship and ship wakes parameters, such as ship length, ship width, ship area, the angle of ship wakes and ship outline from SAR images, it is extremely necessary to remove speckle noise in SAR images before data used in various SAR images ship detection. The use of speckle noise reduction filter depends on the specification for a particular application. Some common filters are widely used in speckle noise reduction, such as the mean filter, the median filter, the lee filter, the enhanced lee filter, the Kuan filter, the frost filter, the enhanced frost filter and gamma filter, but these filters represent some disadvantages in SAR image ship detection because of the various types of ship. Therefore, a mathematical function known as the wavelet transform and multi-resolution analysis were used to localize an SAR ocean image into different frequency components or useful subbands, and effectively reduce the speckle in the subbands according to the local statistics within the bands. Finally, the analysis of the statistical results are presented, which demonstrates the advantages and disadvantages of using wavelet shrinkage techniques over standard speckle filters.

Exposed: younger mothers and breastfeeding.  

PubMed

This qualitative study, conducted by volunteers from the Australian Capital Territory/Southern New South Wales (ACT/SNSW) Branch of the Australian Breastfeeding Association (ABA), explored the breastfeeding experiences of younger mothers (under the age of 26 years) in the ACT by conducting three focus groups. The study aimed to gain an understanding of how, when and where younger mothers want and need to receive breastfeeding information and support. Younger mothers provided important insights into their breastfeeding experiences, which were often characterised by judgement from health professionals and the wider public. A number of key issues were identified including: breastfeeding is far from a cultural norm in our society and as such the risks of artificial baby milk are not clearly understood by many younger mothers; younger mothers are strongly influenced by their partners, mothers and peers and they rely upon them for breastfeeding information and support. Younger mothers indicated that a number of improvements could be made to the way that breastfeeding information and support is currently provided within the ACT. The findings indicated that younger mothers (and their significant others) would benefit from receiving clear, concise and consistent breastfeeding information early on in their pregnancy, that is positive in tone, not necessarily 'young mum' specific and consistent with a 'less is more' approach. Younger mothers indicated that after the birth of their baby this breastfeeding information needs to be complemented by readily accessible, seamless, respectful support for as long as they need to establish breastfeeding and overcome any breastfeeding challenges. The focus group findings were largely consistent with the existing literature available on younger mothers and breastfeeding and provide valuable insights to all stakeholders responsible for providing breastfeeding information and support to younger mothers.

Analysis of ship maneuvering data from simulators  

NASA Astrophysics Data System (ADS)

We analyze complex manuevering histories of ships obtained from training sessions on bridge simulators. Advanced ships are used in fields like offshore oil exploration: dive support vessels, supply vessels, anchor handling vessels, tugs, cable layers, and multi-purpose vessels. Due to high demands from the operations carried out, these ships need to have very high maneuverability. This is achieved through a propulsion system with several thrusters, water jets, and rudders in addition to standard propellers. For some operations, like subsea maintenance, it is crucial that the ship accurately keeps a fixed position. Therefore, bridge systems usually incorporate equipment for Dynamic Positioning (DP). DP is a method to keep ships and semi submersible rigs in a fixed position using the propulsion systems instead of anchors. It may also be used for sailing a vessel from one position to another along a predefined route. Like an autopilot on an airplane, DP may operate without human involvement. The method relies on accurate determination of position from external reference systems like GPS, as well as a continuously adjusted mathematical model of the ship and external forces from wind, waves and currents. In a specific simulator exercise for offshore crews, a ship is to be taken up to an installation consisting of three nearby oil platforms connected by bridges (Frigg field, North Sea), where a subsea inspection is to be carried out. Due to the many degrees of freedom during maneuvering, including partly or full use of DP, the chosen routes vary significantly. In this poster we report preliminary results on representations of the complex maneuvering histories; representations that allow comparison between crew groups, and, possibly, sorting of the different strategic choices behind.

An assessment of simplified methods to determine damage from ship-to-ship collisions  

SciTech Connect

Sandia National Laboratories (SNL) is studying the safety of shipping, radioactive materials (RAM) by sea, the SeaRAM project (McConnell, et al. 1995), which is sponsored by the US Department of Energy (DOE). The project is concerned with the potential effects of ship collisions and fires on onboard RAM packages. Existing methodologies are being assessed to determine their adequacy to predict the effect of ship collisions and fires on RAM packages and to estimate whether or not a given accident might lead to a release of radioactivity. The eventual goal is to develop a set of validated methods, which have been checked by comparison with test data and/or detailed finite element analyses, for predicting the consequences of ship collisions and fires. These methods could then be used to provide input for overall risk assessments of RAM sea transport. The emphasis of this paper is on methods for predicting- effects of ship collisions.

Radiative forcing over ocean by Ship Wakes  

NASA Astrophysics Data System (ADS)

Changes in surface albedo represent one of the main forcing agents that can counteract, to some extent, the positive forcing from increasing greenhouse gas concentrations. Here, we report on enhanced ocean reflectance from ship wakes over the Pacific Ocean near the California coast, where we determined, based on airborne radiation measurements that ship wakes can increase reflected sunlight by more than 100%. We assessed the importance of this increase to climate forcing, where we estimated the global radiative forcing of ship wakes to be -0.00014 ± 53% Wm^-2 assuming a global distribution of 32331 ships of size ?100000 gross tonnage. The forcing is smaller than the forcing of aircraft contrails (-0.007 to +0.02 Wm^-2), but considering that the global shipping fleet has rapidly grown in the last five decades and this trend is likely to continue because of the need of more inter-continental transportation as a result of economic globalization, we argue that the radiative forcing of wakes is expected to be increasingly important especially in harbors and coastal regions.

Sydem - the projet of an antipollution ship  

SciTech Connect

The plans for an antipollution ship were presented by Chantiers France-Dunkerque. Such ships, with or without additional barriers, are under development with the purpose of extending their speed and their range of utilization at sea toward higher waves and worse sea conditions. The Sydem project uses a shape of the hull which converges the pollutant layer toward the collection equipment near the stern. This convergence must be maintained even under less than ideal conditions. The collector system consists of a special trap which retains the pollutant oil; this system has already been model tested. The ship is self-supporting, limited only by its storage capacity for the recovered oil. The next step is the construction of a model prototype.

Standardized analyses of nuclear shipping containers  

SciTech Connect

This paper describes improved capabilities for analyses of nuclear fuel shipping containers within SCALE -- a modular code system for Standardized Computer Analyses for Licensing Evaluation. Criticality analysis improvements include the new KENO V, a code which contains an enhanced geometry package and a new control module which uses KENO V and allows a criticality search on optimum pitch (maximum k-effective) to be performed. The SAS2 sequence is a new shielding analysis module which couples fuel burnup, source term generation, and radial cask shielding. The SAS5 shielding sequence allows a multidimensional Monte Carlo analysis of a shipping cask with code generated biasing of the particle histories. The thermal analysis sequence (HTAS1) provides an easy-to-use tool for evaluating a shipping cask response to the accident capability of the SCALE system to provide the cask designer or evaluator with a computational system that provides the automated procedures and easy-to-understand input that leads to standarization.

Effects of uncertain geoacoustic parameters and coastal shipping densities on shipping noise directionality  

NASA Astrophysics Data System (ADS)

The bearing-elevation directionality of low-frequency shipping noise is influenced both by the sediment geoacoustic parameters and by the coastal shipping density. This study examines the effects of geoacoustic parameter and shipping density uncertainties on noise directionality through simulations for a North Pacific site. The simulations are based in part on stochastic models of the spatial variations of geoacoustic parameters that incorporate: (1) conditional probability densities of the geoacoustic parameters given mean sediment grain size, derived from measurement compilations reported by Hamilton et al. [J. Acoust. Soc. Am. 72,1891], and (2) location-dependent probability densities of the mean grain size, derived from field measurements. [Carlson et al., U.S. Geological Survey Map MF 876]. The simulations also incorporate coastal shipping noise source uncertainties based on models of commercial fishing vessel locations and ship-radiated noise. [Wales and Heitmeyer, J. Acoust. Soc. Am. 111, 1211] The results quantify the effects of the geoacoustic and coastal shipping uncertainties on received low-frequency bearing-elevation noise directionality. Variances in the noise power at horizontal arrival due to geoacoustic uncertainties substantially exceed those associated with uncertainties in the shipping noise source distributions and levels. These results are interpreted in terms of down-slope propagation effects. [Work supported by ONR.

Transport impacts on atmosphere and climate: Shipping  

NASA Astrophysics Data System (ADS)

Emissions of exhaust gases and particles from oceangoing ships are a significant and growing contributor to the total emissions from the transportation sector. We present an assessment of the contribution of gaseous and particulate emissions from oceangoing shipping to anthropogenic emissions and air quality. We also assess the degradation in human health and climate change created by these emissions. Regulating ship emissions requires comprehensive knowledge of current fuel consumption and emissions, understanding of their impact on atmospheric composition and climate, and projections of potential future evolutions and mitigation options. Nearly 70% of ship emissions occur within 400 km of coastlines, causing air quality problems through the formation of ground-level ozone, sulphur emissions and particulate matter in coastal areas and harbours with heavy traffic. Furthermore, ozone and aerosol precursor emissions as well as their derivative species from ships may be transported in the atmosphere over several hundreds of kilometres, and thus contribute to air quality problems further inland, even though they are emitted at sea. In addition, ship emissions impact climate. Recent studies indicate that the cooling due to altered clouds far outweighs the warming effects from greenhouse gases such as carbon dioxide (CO 2) or ozone from shipping, overall causing a negative present-day radiative forcing (RF). Current efforts to reduce sulphur and other pollutants from shipping may modify this. However, given the short residence time of sulphate compared to CO 2, the climate response from sulphate is of the order decades while that of CO 2 is centuries. The climatic trade-off between positive and negative radiative forcing is still a topic of scientific research, but from what is currently known, a simple cancellation of global mean forcing components is potentially inappropriate and a more comprehensive assessment metric is required. The CO 2 equivalent emissions using the global temperature change potential (GTP) metric indicate that after 50 years the net global mean effect of current emissions is close to zero through cancellation of warming by CO 2 and cooling by sulphate and nitrogen oxides.

Archaeology and the Social History of Ships  

NASA Astrophysics Data System (ADS)

Maritime archaeology deals with shipwrecks and is carried out by divers rather than diggers. But this is by no means a marginal branch of archaeology. It embraces maritime history, analyzing changes in ship-building, navigation, reconstructing the infrastructure of waterborne commerce, and offers fresh perspectives on the cultures and societies that produced the ships and sailors. Drawing on detailed and recent case studies, Richard Gould provides an up-to-date review of the field and a clear exposition of new developments in undersea technologies. He also argues for the careful management of underwater cultural resources.

Women as mothers and grandmothers.  

PubMed

This chapter analyzes the literature on women as mothers; research reports published between January 1985 and December 1999 were reviewed. As in the past, almost all of the extant studies analyzed the experience of mothers in their children's first year of life. Although therapeutic suggestions were made in many studies, relatively few interventions have been implemented and evaluated. More studies are needed that go beyond traditional family forms and that explore mothers' role development over the full course of their children's growth and development. Additional longitudinal research that views maternal role development as a process is indicated. PMID:11439789

The SH2-domain of SHIP1 interacts with the SHIP1 C-terminus: impact on SHIP1/Ig-? interaction.  

PubMed

The SH2-containing inositol 5'-phosphatase, SHIP1, negatively regulates signal transduction from the B cell antigen receptor (BCR). The mode of coupling between SHIP1 and the BCR has not been elucidated so far. In comparison to wild-type cells, B cells expressing a mutant IgD- or IgM-BCR containing a C-terminally truncated Ig-? respond to pervanadate stimulation with markedly reduced tyrosine phosphorylation of SHIP1 and augmented activation of protein kinase B. This indicates that SHIP1 is capable of interacting with the C-terminus of Ig-?. Employing a system of fluorescence resonance energy transfer in S2 cells, we can clearly demonstrate interaction between the SH2-domain of SHIP1 and Ig-?. Furthermore, a fluorescently labeled SH2-domain of SHIP1 translocates to the plasma membrane in an Ig-?-dependent manner. Interestingly, whereas the SHIP1 SH2-domain can be pulled-down with phospho-peptides corresponding to the immunoreceptor tyrosine-based activation motif (ITAM) of Ig-? from detergent lysates, no interaction between full-length SHIP1 and the phosphorylated Ig-? ITAM can be observed. Further studies show that the SH2-domain of SHIP1 can bind to the C-terminus of the SHIP1 molecule, most probably by inter- as well as intra-molecular means, and that this interaction regulates the association between different forms of SHIP1 and Ig-?.

Array element localization using ship noise.  

PubMed

This paper describes a method of estimating hydrophone positions in a receiver array using the noise from a passing ship. Relative arrival times of the ship-noise signal between pairs of hydrophones are obtained from several time windows of data (corresponding to different ship locations) by cross-correlating the band-pass filtered time series. The relative arrival times are used as data in an array element localization inversion to estimate both the hydrophone and ship locations based on iterated linearization of the acoustic ray equations. The inversion applies the method of regularization to include prior information such as approximate location estimates and uncertainties for the source and receivers and the expectation that the array shape and or source tracks are smooth functions of position. Linearized and nonlinear (Monte Carlo) estimates of the position errors are in good agreement and indicate a high degree of confidence in the receiver positions (relative uncertainties of approximately 0.2 m in the horizontal and 0.05-0.1 m in the vertical). The ability to improve upon the initial source position estimates depends on the geometry of the problem, as investigated with simulations. PMID:19275297

Automated intelligent video surveillance system for ships  

NASA Astrophysics Data System (ADS)

To protect naval and commercial ships from attack by terrorists and pirates, it is important to have automatic surveillance systems able to detect, identify, track and alert the crew on small watercrafts that might pursue malicious intentions, while ruling out non-threat entities. Radar systems have limitations on the minimum detectable range and lack high-level classification power. In this paper, we present an innovative Automated Intelligent Video Surveillance System for Ships (AIVS3) as a vision-based solution for ship security. Capitalizing on advanced computer vision algorithms and practical machine learning methodologies, the developed AIVS3 is not only capable of efficiently and robustly detecting, classifying, and tracking various maritime targets, but also able to fuse heterogeneous target information to interpret scene activities, associate targets with levels of threat, and issue the corresponding alerts/recommendations to the man-in- the-loop (MITL). AIVS3 has been tested in various maritime scenarios and shown accurate and effective threat detection performance. By reducing the reliance on human eyes to monitor cluttered scenes, AIVS3 will save the manpower while increasing the accuracy in detection and identification of asymmetric attacks for ship protection.

When mothers leave their children behind.  

PubMed

Psychiatry has studied the effect on children of separation from their mothers or primary caregivers, but has not given equal attention to the effect on mothers of separation from their children. This article examines the current literature on separation from the mother's perspective. Following a review of the literature on mothers' attachment behaviors, as evidenced by separation from their very young children due to ordinary circumstances, attention will turn to specific populations of mothers enduring separation from their children in situations of hardship: mothers with mental illness, homeless mothers, mothers in prison, and two groups of working mothers-immigrant mothers and deployed navy mothers. Separation can be experienced as temporary, bringing on anxiety, or may involve a mother's choice between her child's safety and her own wish to keep the child near her, causing a conflict in the mother's feelings. In other situations, separation may be involuntary and long-lasting, inducing symptoms of depression, despair, and grief, all of which are characteristic of loss. The particular conditions of the separation-such as choice, control, and ongoing communication between mother and child-can mitigate the impact of the separation and transform it from a total to a partial loss. Three clinical cases of mothers forced to separate from their children in extreme circumstances are examined, with recommendations for treatment. PMID:16126609

Finding Community Structure in Spatial Maritime Shipping Networks  

NASA Astrophysics Data System (ADS)

This study explores the community structure in spatial maritime shipping networks. As compared with air transportation networks and urban road networks, ports in spatial maritime shipping networks have smaller connections due to the physical confinement. A new divisive algorithm is proposed for detecting community structure in spatial maritime shipping networks. At each iteration for modularity optimization, the length of each edge is successively updated, instead of edge removal used in the conventional divisive method. Finally, numerical experiments based on the global maritime shipping network are carried out to account for the properties of community structure in spatial maritime shipping networks.

GOME-2 satellite observations of NOx emissions from ships  

NASA Astrophysics Data System (ADS)

The volume of international shipping has been rapidly increasing over the last decades, and further increases are expected for the coming years. A large fraction of the shipping is close to coastal areas but for intercontinental transport, shipping routes also pass through the remote oceans. As the volume of transported goods is increasing, so is the amount of shipping related pollutant emissions into the marine boundary layer. As result of the lack of legislation on shipping emissions, in particular in international waters, in combination with substantial emission reductions for many land based sources, the relative importance of pollution from ships is increasing. Satellite observations of NO2 and HCHO by GOME and SCIAMACHY have been used to identify shipping emissions mainly in the Indian Ocean, where high vessel densities and low background pollution levels facilitate the detection of small signals. With the better spatial coverage of recent satellite instruments such as GOME-2 and OMI, the statistics improved and better detection limits can now be achieved. In this study, three years of GOME-2 data of NO2 have been systematically examined for shipping signals. Compared to previous studies, additional shipping tracks could be identified in the NO2 maps. Comparison with SCIAMACHY measurements shows interesting changes in the paths taken by the ships in the Gulf of Aden and the Indian Ocean. The observed patterns in ship emissions will be discussed with respect to reported vessel densities and GOME-2 measurement uncertainties.

H1616 Shipping Container Radiographic Inspection Report  

SciTech Connect

The HI616 shipping container is a certified type B(U) packaging used by the Department of Energy (DOE) to ship tritium in support of defense programs. During the 1997 recertification of the container, DOE became concerned about the possible cracking of the polyurethane foam in the overpacks of the 2300 containers currently in service. In response, Sandia National Laboratories (SNL) initiated a radiographic inspection program to determine if cracking of the foam was occurring in the H1616 overpacks. SNL developed the radiographic technique for inspecting the foam and contracted the Savannah River Site's Tritium Engineering division to inspect a representative sample of overpacks in service. This report details the development process and the results of all of the radiography performed both at SNL and Savannah River.

Technique for ship/wake detection  

DOEpatents

An automated ship detection technique includes accessing data associated with an image of a portion of Earth. The data includes reflectance values. A first portion of pixels within the image are masked with a cloud and land mask based on spectral flatness of the reflectance values associated with the pixels. A given pixel selected from the first portion of pixels is unmasked when a threshold number of localized pixels surrounding the given pixel are not masked by the cloud and land mask. A spatial variability image is generated based on spatial derivatives of the reflectance values of the pixels which remain unmasked by the cloud and land mask. The spatial variability image is thresholded to identify one or more regions within the image as possible ship detection regions.

Asbestos and ship-building: fatal consequences.  

PubMed

The severe bombing of Belfast in 1941 had far-reaching consequences. Harland and Wolff was crippled. The British Merchant Ship Building Mission to the U.S.A. was being constrained by the U.K. treasury. On being told of the Belfast destruction, the British Mission and the United States Maritime Commission were emboldened. The result was 2,710 Liberty Ships launched to a British design. The necessary asbestos use associated with this and other shipbuilding, after a quarter century or more latency, is a genesis of malignancy killing thousands. Reversal of studies on asbestos limitation of fire propagation was crucial to Allied strategic planning of mass-fires which resulted in the slaughter of one to two million civilians. Boston and Belfast institutions made seminal discoveries about asbestos use and its sequelae. PMID:18956802

Medieval orality, mothers, and bonding.  

PubMed

The role of women in the Middle Ages was vilification, veneration, and exclusion. Due to the high rates of maternal and infant mortality bonding shifted from the mother-child dyad to one in which the Church, Holy Family, and king acted as pseudo-parents. In art this is suggested by the virtual absence of eye contact between the Virgin and Christ-child. Frustration of early oral needs consequent to lack of adequate mother-child bonding prompted a reactive emphasis on orality in art and legend. A decrease in infant mortality and a reciprocal improvement in mother child bonding contributed to cultural shifts in how self-realization would be accomplished during the Renaissance and in the later emergence of secular humanism.

WORLD SURFACE CURRENTS FROM SHIP'S DRIFT OBSERVATIONS  

SciTech Connect

Over 4 million observations of ship's drift are on file at the U.S. National Oceanographic Data Centre, in Washington, D. C., representing a vast amount of information on ocean surface currents. The observed drift speeds are dependent on the frequency of occurence of the particular current speeds and the frequency of observation. By comparing frequency of observation with the drift speeds observed it is possible to confirm known current patterns and detect singularities in surface currents.

Light absorbing carbon emissions from commercial shipping  

NASA Astrophysics Data System (ADS)

Extensive measurements of the emission of light absorbing carbon aerosol (LAC) from commercial shipping are presented. Vessel emissions were sampled using a photoacoustic spectrometer in the Gulf of Mexico region. The highest emitters (per unit fuel burnt) are tug boats, thus making significant contributions to local air quality in ports. Emission of LAC from cargo and non cargo vessels in this study appears to be independent of engine load. Shipping fuel consumption data (2001) was used to calculate a global LAC contribution of 133(+/-27) Ggyr-1, or ~1.7% of global LAC. This small fraction could have disproportionate effects on both air quality near port areas and climate in the Arctic if direct emissions of LAC occur in that region due to opening Arctic sea routes. The global contribution of this LAC burden was investigated using the MOZART model. Increases of 20-50 ng m-3 LAC (relative increases up to 40%) due to shipping occur in the tropical Atlantic, Indonesia, central America and the southern regions of South America and Africa.

Hospitalisations among seafarers on merchant ships  

PubMed Central

Aims: To study morbidity among active seafarers in the merchant navy in order to clarify possible work related morbidity and the morbidity related to work and lifestyle where possible preventive measures may be initiated. Methods: From a register in the Danish Maritime Authority a cohort of Danish merchant seafarers who had been actively employed at sea in 1995 was identified. For each seafarer, information on all employment periods at sea, charge aboard, and ship was available. The cohort was linked with the National In-patient Register in Denmark. Standardised hospitalisation ratios (SHRs) were calculated for all major diagnostic groups using all gainfully employed as reference. Results: Seafarers were shown to be inhomogeneous, with significant differences in SHRs for the same disease groups between different groups of seafarers depending on charge and ship type. SHRs for lifestyle related diseases were high, although rates for acute conditions, such as acute myocardial infarction, were low, probably due to referral bias, as acute conditions are likely to cause hospitalisation abroad, and thus are not included in the study. SHRs for injury and poisoning were high, especially for ratings and officers aboard small ships. Conclusion: Despite pre-employment selection, a large proportion of the seafarers constitute a group of workers with evidence of poor health probably caused by lifestyle. The subgroups with high risk of hospitalisation due to lifestyle related diseases also had an increased risk of hospitalisation due to injury and poisoning.

DEVELOPMENT OF THE BULK TRITIUM SHIPPING PACKAGING  

SciTech Connect

A new radioactive shipping packaging for transporting bulk quantities of tritium, the Bulk Tritium Shipping Package (BTSP), has been designed for the Department of Energy (DOE) as a replacement for a package designed in the early 1970s. This paper summarizes significant design features and describes how the design satisfies the regulatory safety requirements of the Code of Federal Regulations and the International Atomic Energy Agency. The BTSP design incorporates many improvements over its predecessor by implementing improved testing, handling, and maintenance capabilities, while improving manufacturability and incorporating new engineered materials. This paper also discusses the results from testing of the BTSP to 10 CFR 71 Normal Conditions of Transport and Hypothetical Accident Condition events. The programmatic need of the Department of Energy (DOE) to ship bulk quantities of tritium has been satisfied since the late 1970s by the UC-609 shipping package. The current Certificate of Conformance for the UC-609, USA/9932/B(U) (DOE), will expire in late 2011. Since the UC-609 was not designed to meet current regulatory requirements, it will not be recertified and thereby necessitates a replacement Type B shipping package for continued DOE tritium shipments in the future. A replacement tritium packaging called the Bulk Tritium Shipping Package (BTSP) is currently being designed and tested by Savannah River National Laboratory (SRNL). The BTSP consists of two primary assemblies, an outer Drum Assembly and an inner Containment Vessel Assembly (CV), both designed to mitigate damage and to protect the tritium contents from leaking during the regulatory Hypothetical Accident Condition (HAC) events and during Normal Conditions of Transport (NCT). During transport, the CV rests on a silicone pad within the Drum Liner and is covered with a thermal insulating disk within the insulated Drum Assembly. The BTSP packaging weighs approximately 500 lbs without contents and is 50-1/2 inches high by 24-1/2 inches in outside diameter. With contents the gross weight of the BTSP is 650 lbs. The BTSP is designed for the safe shipment of 150 grams of tritium in a solid or gaseous state. To comply with the federal regulations that govern Type B shipping packages, the BTSP is designed so that it will not lose tritium at a rate greater than the limits stated in 10CFR 71.51 of 10{sup -6} A2 per hour for the 'Normal Conditions of Transport' (NCT) and an A2 in 1 week under 'Hypothetical Accident Conditions' (HAC). Additionally, since the BTSP design incorporates a valve as part of the tritium containment boundary, secondary containment features are incorporated in the CV Lid to protect against gas leakage past the valve as required by 10CFR71.43(e). This secondary containment boundary is designed to provide the same level of containment as the primary containment boundary when subjected to the HAC and NCT criteria.

Emissions from Ships with respect to Their Effects on Clouds.  

NASA Astrophysics Data System (ADS)

Emissions of particles, gases, heat, and water vapor from ships are discussed with respect to their potential for changing the microstructure of marine stratiform clouds and producing the phenomenon known as `ship tracks.' Airborne measurements are used to derive emission factors of SO2 and NO from diesel-powered and steam turbine-powered ships, burning low-grade marine fuel oil (MFO); they were 15-89 and 2-25 g kg1 of fuel burned, respectively. By contrast a steam turbine-powered ship burning high-grade navy distillate fuel had an SO2 emission factor of 6 g kg1.Various types of ships, burning both MFO and navy distillate fuel, emitted from 4 × 1015 to 2 × 1016 total particles per kilogram of fuel burned (4 × 1015-1.5 × 1016 particles per second). However, diesel-powered ships burning MFO emitted particles with a larger mode radius (0.03-0.05 m) and larger maximum sizes than those powered by steam turbines burning navy distillate fuel (mode radius 0.02 m). Consequently, if the particles have similar chemical compositions, those emitted by diesel ships burning MFO will serve as cloud condensation nuclei (CCN) at lower supersaturations (and will therefore be more likely to produce ship tracks) than the particles emitted by steam turbine ships burning distillate fuel. Since steam turbine-powered ships fueled by MFO emit particles with a mode radius similar to that of diesel-powered ships fueled by MFO, it appears that, for given ambient conditions, the type of fuel burned by a ship is more important than the type of ship engine in determining whether or not a ship will produce a ship track. However, more measurements are needed to test this hypothesis.The particles emitted from ships appear to be primarily organics, possibly combined with sulfuric acid produced by gas-to-particle conversion of SO2. Comparison of model results with measurements in ship tracks suggests that the particles from ships contain only about 10% water-soluble materials. Measurements of the total particles entering marine stratiform clouds from diesel-powered ships fueled by MFO, and increases in droplet concentrations produced by these particles, show that only about 12% of the particles serve as CCN.The fluxes of heat and water vapor from ships are estimated to be 2-22 MW and 0.5-1.5 kg s1, respectively. These emissions rarely produced measurable temperature perturbations, and never produced detectable perturbations in water vapor, in the plumes from ships. Nuclear-powered ships, which emit heat but negligible particles, do not produce ship tracks. Therefore, it is concluded that heat and water vapor emissions do not play a significant role in ship track formation and that particle emissions, particularly from those burning low-grade fuel oil, are responsible for ship track formation. Subsequent papers in this special issue discuss and test these hypotheses.

MotherJones.com: The Mother Jones 400  

NSDL National Science Digital Library

Using data from the Federal Election Commission which was compiled by the Center for Responsive Politics (CRP) (see the July 10, 1999 Scout Report), Mother Jones has put together an eye-opening Website which reveals the nation's top 400 financial political contributors and what they may be expecting for their contributions. Users may browse the list of contributors by industry or individual donor rank or search by donor, state, industry, party, or recipient. The rankings include donor name, amount given and to whom, their rank in 1998, and their industry. This information is interesting and useful, but it is also available elsewhere. The real value of the Mother Jones 400 lies in its profiles of the donors and the industry summaries, which are an excellent resource for learning about the various individuals, not always well known, who influence government policy and legislation with their donations and personal relationships with our representatives.

Health promotion in the Finnish shipping industry.  

PubMed

In autumn 1997 a pilot project was started in Finland to develop methods for promoting the health of sailors. Four Finnish shipping companies, (4 cargo ships and 2 passenger-cruise ferries), with altogether 730 sailors participated in the project. Special attention was paid to individuals with health problems and those who generally did not take care of their own health or fitness. Three-quarters of the respondents saw their health as good and one fifth as fair. Thirty-four persons responded that their working capacity was poor. 154 sailors were selected into further physical fitness evaluations. The main task of the project team was to activate sailors to take care of their own health and well-being. The health-promoting activities were directed especially at those persons who needed it. Information lectures concerning healthier eating habits and meals were given. Anti-smoking and anti-alcohol drinking information was given. On board one cruise ferry a project was started on how to react as early as possible to alcohol abuse among seafarers. Courses on shore for sailors were arranged to improve their physical fitness and to increase their resting benefit between working periods at sea. The intervention time was one year. Information about smoking and alcohol led to reduced alcohol consumption. The sailors had started to exercise more often both on board ship and on shore. Those who had increased their physical exercise during free time more often found their own health and working ability to have improved than those who had not changed their exercise habits. It appeared that health intervention projects are really needed especially by older sailors. The results also showed that positive effects could be achieved in the fitness of sailors. Better fitness was good for their health and also increased the work safety. PMID:11817841

Amphibious assault ship local area network  

NASA Astrophysics Data System (ADS)

The Amphibious Assault Ship, USS Makin Island (LHD 8) encompasses multiple systems to support the Navy's missions. The USS Makin Island systems include ballast, steering, propulsion, fresh water, power distribution as well as many damage control systems. The systems utilize various signal types to operate the systems while receiving signals to monitor the system components via the Machinery Control System (MCS). Many input/output (I/O) signals exchange information between the MCS and the various systems' equipment. The MCS monitors and controls the system components using a Human Machine Interface (HMI). The user-friendly HMI permits authorized operators to perform many daily operations remotely allowing operators to address system issues from multiple MCS units located throughout the ship. The MCS utilizes a fiber optic network that serves as the backbone connecting the Local Area Network (LAN) switches via blown optical fiber. Each MCS unit is intricately connected to the LAN switches for maximum redundancy via fiber optic connections to non-adjacent LAN switches to ensure system communications continuity. The LAN switches are connected in a star configuration for added system survivability. The backbone's blown fiber is designed and installed with a sufficient percentage of spare blowing tubes to ensure the potential of future growth. Conventional optical fiber is used to interconnect the MCS consoles, workstations, and Data Acquisition Units (DAU) to each other and the LAN switches. The conventional fiber also contains sufficient spare conductors in a combination of eight and four conductor optical fiber. The network backbone is redundantly connected allowing for continuous transmission of information throughout the ship.

Alternative Sources of Energy in Shipping  

NASA Astrophysics Data System (ADS)

In recent years, there have been strategy changes in international and European policies and procedures about the environment and sustainable development. The focus has been on the agents and activities that exhaust natural resources and harm the environment. The International Maritime Organization (IMO) and shipping companies' international organisations are trying to reduce the polluting emissions and greenhouse gases generated by vessels. This article looks at various alternative energy sources that can be used to power vessels and their auxiliary equipment, as well as at their economic and environmental repercussions on the transport of goods by sea.

Precise Positioning of Ships for Maritime Disasters Prevention Using GPS  

NASA Astrophysics Data System (ADS)

Most ships use the marine DGPS (Differential Global Positioning System) service to know position information in the sea. In Korea, the Ministry of Land Transport and Maritime Affairs (MLTM) provides the nationwide DGPS (NDGPS) service to users trying to secure the safety of traffic of ships. The precision of ship position information obtained by the MLTM NDGPS system is about 1-2m. When ships pass through courses under bridges, ship collisions can occur with the bridges because of the few meter-level precision of position information. In this study, as a feasibility test, we estimated positions of ships at sea to predict the collisions between ships and bridges using DGPS, carrier phase DGPS (CDGPS), and precise point positioning (PPP) techniques were used. We conducted ship borne GPS observations in the south sea of Korea. To process the GPS data, GIPSY-OASIS (GPS Inferred Positioning System-Orbit Analysis and Simulation Software) developed by the Jet Propulsion Laboratory and CDGPS MATLAB program developed by Korea Space Research Institute were used. Antenna phase center variations, ocean tidal loading displacements, and azimuthal gradients of the atmosphere were corrected or estimated as standard procedures of high-precision GIPSY-OASIS data processing. As a result, the position precision decreased to decimeter-level with increasing the quantity of motion such as velocity, pitch and roll of the ship and buoys.

The complex network of global cargo ship movements  

PubMed Central

Transportation networks play a crucial role in human mobility, the exchange of goods and the spread of invasive species. With 90 per cent of world trade carried by sea, the global network of merchant ships provides one of the most important modes of transportation. Here, we use information about the itineraries of 16 363 cargo ships during the year 2007 to construct a network of links between ports. We show that the network has several features that set it apart from other transportation networks. In particular, most ships can be classified into three categories: bulk dry carriers, container ships and oil tankers. These three categories do not only differ in the ships' physical characteristics, but also in their mobility patterns and networks. Container ships follow regularly repeating paths whereas bulk dry carriers and oil tankers move less predictably between ports. The network of all ship movements possesses a heavy-tailed distribution for the connectivity of ports and for the loads transported on the links with systematic differences between ship types. The data analysed in this paper improve current assumptions based on gravity models of ship movements, an important step towards understanding patterns of global trade and bioinvasion.

Effect of stern hull shape on turning circle of ships  

NASA Astrophysics Data System (ADS)

Many factors such as: stern hull shape, length, draught, trim, propulsion system and external forces affecting the drift angle influence rate of turn and size of turning circle of ships. This paper discusses turning circle characteristics of U and V stern hull shape of Very Large Crude Oil Carrier (VLCC) ships. The ships have same principal dimension such as length, beam, and draught. The turning circle characteristics of the VLCC ships are simulated at 35 degree of rudder angle. In the analysis, firstly, turning circle performance of U-type VLCC ship is simulated. In the simulation, initial ship speed is determined using given power and rpm. Hydrodynamic derivatives coefficients are determined by including effect of fullness of aft run. Using the obtained, speed and hydrodynamic coefficients, force and moment acting on hull, force and moment induced by propeller, force and moment induced by rudder are determined. Finally, ship trajectory, ratio of speed, yaw angle and drift angle are determined. Results of simulation results of the VLCC ship are compared with the experimental one as validation. Using the same method, V-type VLCC is simulated and the simulation results are compared with U-type VLCC ship. Results shows the turning circle of U-type is larger than V-type due to effect stern hul results of simulation are.

[Medicine aboard cruise ships--law insurance specifics].  

PubMed

The booming cruise industry, associated with ships with more passengers and crew on board, results in growing medical needs for the ship doctor. The ship's doctor insurance policy includes different jurisdictions, namely national law, international law, tort law, insurance law and labor law. In addition, international agreements must be taken into account, which complicates the design of an adequate insurance policy. Equally high are the costs and defense costs for the ship's doctor in case of liability. In order to limit the liability for all parties is to ask for appropriately qualified medical staff, hired on board. PMID:23589048

Contraceptive practices of teenage mothers.  

PubMed

This study explores the contraceptive attitudes and practices of a sample of adolescent mothers who participated in a teen parents project at Howard University. Members of the sample were interviewed 3 times; twice prior to their entry into the intervention program and once afterwards. Concern over the side effects of contraceptives was the primary reason that mothers in this sample gave for not using contraception at the time they became pregnant. Motivational factors were secondary, and lack of information about contraception and fertility ranked 3rd. Recommendations are made for the dissemination of more complete information about contraceptive methods to inner city adolescents and for closer follow-up of teenage clients from family planning facilities.

Shipping emissions associated with increased cardiovascular hospitalizations  

NASA Astrophysics Data System (ADS)

Previous studies have suggested nickel (Ni) and vanadium (V) as the likely constituents that are partially responsible for health effects associated with particulate matter pollution. The authors aimed to examine the effects of Ni and V in PM10, the indices of shipping emissions, on emergency hospitalizations for cardiovascular diseases (CVD) in Hong Kong. Daily PM10 speciation data across six monitoring stations in Hong Kong during 1998–2007 were collected. Generalized additive Poisson models with single-day lags were used to estimate the excess risks of emergency hospital admissions for CVD associated with Ni and V, after adjusted for major PM10 chemical species and criteria gaseous pollutants. The excess risks for inter-quartile range (IQR) increases of Ni and V on the same day and previous six days (lag0 ˜ lag6) were estimated. Ni in PM10 was associated with a 1.25% (95%CI: 0.81–1.68%) increase of total emergency CVD admissions on the same day, while lag0 V was associated with a 0.95% (95%CI: 0.55–1.35%) elevated CVD admissions. The associations were not sensitive to the further adjustment for co-pollutants. Ni appeared to correspond better than V to cardiovascular health. Controlling shipping emissions from residual oil combustion in the port cities like Hong Kong is particularly important.
