The Hirsch index (h-index) quantifies research publication productivity for an individual, and has widely been considered a valuable measure of academic influence. In 2010, the Physician Payments Sunshine Act (PPSA) was introduced as a way to increase transparency regarding U.S. physician-industry relationships. The purpose of this study was to investigate the relationship between industry payments and academic influence as measured by the h-index and number of publications among orthopaedic surgeons. We also examined the relationship of the h-index to National Institutes of Health (NIH) funding. The h-indices of faculty members at academic orthopaedic surgery residency programs were obtained using the Scopus database. The PPSA web site was used to abstract their 2014 industry payments. NIH funding data were obtained from the NIH web site. Mann-Whitney U testing and Spearman correlations were used to explore the relationships. Of 3,501 surgeons, 78.3% received nonresearch payments, 9.2% received research payments, and 0.9% received NIH support. Nonresearch payments ranged from $6 to $4,538,501, whereas research payments ranged from $16 to $517,007. Surgeons receiving NIH or industry research funding had a significantly higher mean h-index and number of publications than those not receiving such funding. Surgeons receiving nonresearch industry payments had a slightly higher mean h-index and number of publications than those not receiving these kinds of payments. Both the h-index and the number of publications had weak positive correlations with industry nonresearch payment amount, industry research payment amount, and total number of industry payments. There are large differences in industry payment size and distribution among academic surgeons. The small percentage of academic surgeons who receive industry research support or NIH funding tend to have higher h-indices. For the overall population of orthopaedic surgery faculty, the h-index correlates poorly with the dollar amount and the total number of industry research payments. Regarding nonresearch industry payments, the h-index also appears to correlate poorly with the number and the dollar amount of payments. These results are encouraging because they suggest that industry bias may play a smaller role in the orthopaedic literature than previously thought.

Influence of social norms and palatability on amount consumed and food choice.

PubMed

Pliner, Patricia; Mann, Nikki

2004-04-01

In two parallel studies, we examined the effect of social influence and palatability on amount consumed and on food choice. In Experiment 1, which looked at amount consumed, participants were provided with either palatable or unpalatable food; they were also given information about how much previous participants had eaten (large or small amounts) or were given no information. In the case of palatable food, participants ate more when led to believe that prior participants had eaten a great deal than when led to believe that prior participants had eaten small amounts or when provided with no information. This social-influence effect was not present when participants received unpalatable food. In Experiment 2, which looked at food choice, some participants learned that prior participants had chosen the palatable food, others learned that prior participants had chosen the unpalatable food, while still others received no information about prior participants' choices. The social-influence manipulation had no effect on participants' food choices; nearly all of them chose the palatable food. The results were discussed in the context of Churchfield's (1995) distinction between judgments about matters of fact and judgments about preferences. The results were also used to illustrate the importance of palatability as a determinant of eating behavior.

2016-01-01

Emergent rock outcrops are common in terrestrial ecosystems. However, little research has been conducted regarding their surface function in redistributing organic carbon and nutrient fluxes to soils nearby. Water that fell on and ran off 10 individual rock outcrops was collected in three 100 × 100 m plots within a rock desertification ecosystem, an anthropogenic forest ecosystem, and a secondary forest ecosystem between June 2013 and June 2014 in Shilin, SW China. The concentrations of total organic carbon (TOC), total nitrogen (N), total phosphorus (P), and potassium (K) in the water samples were determined during three seasons, and the total amounts received by and flowing out from the outcrops were calculated. In all three ecosystems, TOC and N, P, and K were found throughout the year in both the water received by and delivered to nearby soil patches. Their concentrations and amounts were generally greater in forested ecosystems than in the rock desertification ecosystem. When rock outcrops constituted a high percentage (≥ 30%) of the ground surface, the annual export of rock outcrop runoff contributed a large amount of organic carbon and N, P, and K nutrients to soil patches nearby by comparison to the amount soil patches received via atmospheric deposition. These contributions may increase the spatial heterogeneity of soil fertility within patches, as rock outcrops of different sizes, morphologies, and emergence ratios may surround each soil patch.

Advanced heat receiver conceptual design study

Kesseli, James; Saunders, Roger; Batchelder, Gary

1988-01-01

Solar Dynamic space power systems are candidate electrical power generating systems for future NASA missions. One of the key components of the solar dynamic power system is the solar receiver/thermal energy storage (TES) subsystem. Receiver development was conducted by NASA in the late 1960's and since then a very limited amount of work has been done in this area. Consequently the state of the art (SOA) receivers designed for the IOC space station are large and massive. The objective of the Advanced Heat Receiver Conceptual Design Study is to conceive and analyze advanced high temperature solar dynamic Brayton and Stirling receivers. The goal is to generate innovative receiver concepts that are half of the mass, smaller, and more efficient than the SOA. It is also necessary that these innovative receivers offer ease of manufacturing, less structural complexity and fewer thermal stress problems. Advanced Brayton and Stirling receiver storage units are proposed and analyzed in this study which can potentially meet these goals.

Epstein, Marina; Ward, L. Monique

2011-01-01

Although parents are assumed to be children’s primary models of socialization when it comes to gender, little is known about direct communication of gendered values in the family. Accordingly, this study assessed the amount and content of recalled parental gender socialization messages using data from 291 U.S. college undergraduates attending a large Midwestern university and 259 U.S. adolescents enrolled in public high schools in the Midwest. The study examined the amount and content of parental communications of five gendered discourses and then tested for connections to current gender beliefs. Findings indicate that gender socialization may be quite similar for sons and daughters, with some evidence of gender typing in patterns of communication. No significant age differences emerged in the patterns of socialization, although high school students reported receiving greater amounts of communication than college students on two of the five discourses. In general, receiving messages promoting traditional gender roles was associated with more traditional gender beliefs (and vice versa), although interpretation of some messages appeared to vary by gender.

1991-01-01

Future space missions, such as those associated with the Space Exploration Initiative (SEI), will require large amounts of power for operation of bases, rovers, and orbit transfer vehicles. One method for supplying this power is to beam power from a spaced based or Earth based laser power station to a receiver where laser photons can be converted to electricity. Previous research has described such laser power stations orbiting the Moon and beaming power to a receiver on the surface of the Moon by using arrays of diode lasers. Photovoltaic converters that can be efficiently used with these diode lasers are described.

Forest amount affects soybean productivity in Brazilian agricultural frontier

Over the past three decades, large tracts of tropical forests have been converted to crop and pasturelands across southern Amazonia, largely to meet the increasing worldwide demand for protein. As the world's population continue to grow and consume more protein per capita, forest conversion to grow more crops could be a potential solution to meet such demand. However, widespread deforestation is expected to negatively affect crop productivity via multiple pathways (e.g., thermal regulation, rainfall, local moisture, pest control, among others). To quantify how deforestation affects crop productivity, we modeled the relationship between forest amount and enhanced vegetation index (EVI—a proxy for crop productivity) during the soybean planting season across southern Amazonia. Our hypothesis that forest amount causes increased crop productivity received strong support. We found that the maximum MODIS-based EVI in soybean fields increased as a function of forest amount across three spatial-scales, 0.5 km, 1 km, 2 km, 5 km, 10 km, 15 km and 20 km. However, the strength of this relationship varied across years and with precipitation, but only at the local scale (e.g., 500 meters and 1 km radius). Our results highlight the importance of considering forests to design sustainable landscapes.

Surfactant and pulmonary blood flow distributions following treatment of premature lambs with natural surfactant.

1984-01-01

Prematurely delivered lambs were treated with radiolabeled natural surfactant by either tracheal instillation at birth and before the onset of mechanical ventilation, or after 23 +/- 1 (+/- SE) min of mechanical ventilation. Right ventricular blood flow distributions, left ventricular outputs, and left-to-right ductal shunts were measured with radiolabeled microspheres. After sacrifice, the lungs of lambs receiving surfactant at birth inflated uniformly with constant distending pressure while the lungs of lambs treated after a period of ventilation had aerated, partially aerated, and atelectatic areas. All lungs were divided into pieces which were weighed and catalogued as to location. The amount of radiolabeled surfactant and microsphere-associated radioactivity in each piece of lung was quantified. Surfactant was relatively homogenously distributed to pieces of lung from lambs that were treated with surfactant at birth; 48% of lung pieces received amounts of surfactant within +/- 25% of the mean value. Surfactant was preferentially recovered from the aerated pieces of lungs of lambs treated after a period of mechanical ventilation, and the distribution of surfactant to these lungs was very nonhomogeneous. Right ventricular blood flow distributions to the lungs were quite homogeneous in both groups of lambs. However, in 8 of 12 lambs, pulmonary blood flow was preferentially directed away from those pieces of lung that received relatively large amounts of surfactant and toward pieces of lung that received less surfactant. This acute redirection of pulmonary blood flow distribution may result from the local changes in compliances within the lung following surfactant instillation. PMID:6546766

2009-01-01

Objectives Unlike information provided for research, information disclosed to patients for treatment or procedures is largely unregulated and, as such, there is likely considerable variability in the type and amount of disclosure. This study was designed to examine the nature of information provided to parents regarding options for postoperative pain control and their understanding thereof. Methods 187 parents of children scheduled to undergo a surgical procedure requiring inpatient postoperative pain control completed questionnaires that elicited information regarding their perceptions and understanding of, and satisfaction with, information regarding postoperative pain management. Results Results showed that there was considerable variability in the content and amount of information provided to parents based on the method of postoperative pain control provided. Parents whose child received Patient Controlled Analgesia (PCA) were given significantly (P< 0.025) more information on the risks and benefits compared to those receiving Nurse Controlled or intravenous-prn (NCA or IV) analgesia. Approximately one third of parents had no understanding of the risks associated with postoperative pain management. Parents who received pain information preoperatively and who were given information regarding the risks and benefits had improved understanding compared to parents who received no or minimal information (P< 0.001). Furthermore, information that was deemed unclear or insufficient resulted in decreased parental understanding. Discussion These results demonstrate the variability in the type and amount of information provided to parents regarding their child’s postoperative pain control and reinforce the importance of clear and full disclosure of pain information, particularly with respect to the risks and benefits.

Verma, Vivek

2017-10-01

To quantitate financial conflicts of interest (FCOIs) among radiation oncology peer-reviewers, specifically editorial board members of the 3 American Society for Radiation Oncology journals. The public Centers for Medicare and Medicaid Services Open Payments database delineates payments in 3 categories (general payments, research funding, and company ownership). After excluding non-US and non-MDs, names of board members were searched. Values of each FCOI were extracted for 2013 to 2015 and compiled. Of 85 board members, 65 (76%) received any form of payment during the overall period. The majority of delivered payments were general payments: 59 (69%) received at least 1 general payment during these 3 years. In each year, 9 board members (11%) received research funding, and 3 board members (4%) reported company ownership. Over the studied period, all board members received a sum total of $5,387,985; this was composed of $665,801 (12%) in general payments, $3,758,968 (70%) in research funding, and $963,216 (18%) in company ownership. The mean general payment and research funding amounts (all members) were $2,621 and $14,741, respectively. Median (interquartile range) general payments and research funding only in board members receiving payments were $419 ($91-$5072) and $56,250 ($13,345-$200,000), respectively. When assessing general payments according to amount, the vast majority of editorial board members received lower-quantity or no such payments, along with a smaller proportion that received higher-volume payments. The most frequent sources of general payments were Varian, Elekta, and Bristol-Myers Squibb. Merck and Varian were the most frequent funding sources for research payments. In this population, the majority of FCOIs were general payments, but research funding comprised the highest monetary sums. Large-volume FCOIs do not apply to the vast majority of editorial board members, implying that the maintained integrity of academic peer-review is likely not influenced to a large extent by FCOIs.

Conically scanned lidar telescope using holographic optical elements

NASA Technical Reports Server (NTRS)

Schwemmer, Geary K.; Wilkerson, Thomas D.

1992-01-01

Holographic optical elements (HOE) using volume phase holograms make possible a new class of lightweight scanning telescopes having advantages for lidar remote sensing instruments. So far, the only application of HOE's to lidar has been a non-scanning receiver for a laser range finder. We introduce a large aperture, narrow field of view (FOV) telescope used in a conical scanning configuration, having a much smaller rotating mass than in conventional designs. Typically, lidars employ a large aperture collector and require a narrow FOV to limit the amount of skylight background. Focal plane techniques are not good approaches to scanning because they require a large FOV within which to scan a smaller FOV mirror or detector array. Thus, scanning lidar systems have either used a large flat scanning mirror at which the receiver telescope is pointed, or the entire telescope is steered. We present a concept for a conically scanned lidar telescope in which the only moving part is the HOE which serves as the primary collecting optic. We also describe methods by which a multiplexed HOE can be used simultaneously as a dichroic beamsplitter.

The dust cloud of the century

Robock, A.

1983-02-01

The structure and composition of the dust cloud from the 4 April 1982 eruption of the El Chichon volcano in Chiapas state, Mexico, is examined and the possible effects of the dust cloud on the world's weather patterns are discussed. Observations of the cloud using a variety of methods are evaluated, including data from the GOES and NOAA-7 weather satellites, vertically pointing lidar measurements, the SME satellite, and the Nimbus-7 satellite. Studies of the gaseous and particulate composition of the cloud reveal the presence of large amounts of sulfuric acid particles, which have a long mean residence time in the atmosphere and have a large effect on the amount of solar radiation received at the earth's surface by scattering several percent of the radiation back to space. Estimates of the effect of this cloud on surface air temperature changes are presented based on findings from climate models.

Factors associated with the amount of public home care received by elderly and intellectually disabled individuals in a large Norwegian municipality.

2016-05-01

This study reports an analysis of factors associated with home care use in a setting in which long-term care services are provided within a publicly financed welfare system. We considered two groups of home care recipients: elderly individuals and intellectually disabled individuals. Routinely collected data on users of public home care in the municipality of Trondheim in October 2012, including 2493 people aged 67 years or older and 270 intellectually disabled people, were used. Multivariate regression analysis was used to analyse the relationship between the time spent in direct contact with recipients by public healthcare personnel and perceived individual determinants of home care use (i.e. physical disability, cognitive impairment, diagnoses, age and gender, as well as socioeconomic characteristics). Physical disability and cognitive impairment are routinely registered for long-term care users through a standardised instrument that is used in all Norwegian municipalities. Factor analysis was used to aggregate the individual items into composite variables that were included as need variables. Both physical disability and cognitive impairment were strong predictors of the amount of received care for both elderly and intellectually disabled individuals. Furthermore, we found a negative interaction effect between physical disability and cognitive impairment for elderly home care users. For elderly individuals, we also found significant positive associations between weekly hours of home care and having comorbidity, living alone, living in a service flat and having a safety alarm. The reduction in the amount of care for elderly individuals living with a cohabitant was substantially greater for males than for females. For intellectually disabled individuals, receiving services involuntarily due to severe behavioural problems was a strong predictor of the amount of care received. Our analysis showed that routinely collected data capture important predictors of home care use and thus facilitate both short-term budgeting and long-term planning of home care services. © 2015 John Wiley & Sons Ltd.

Large repayments of premium subsidies may be owed to the IRS if family income changes are not promptly reported.

PubMed

Jacobs, Ken; Graham-Squire, Dave; Gould, Elise; Roby, Dylan

2013-09-01

Subsidies for health insurance premiums under the Affordable Care Act are refundable tax credits. They can be taken when taxes are filed or in advance, as reductions in monthly premiums that must be reconciled at tax filing. Recipients who take subsidies in advance will receive tax refunds if their subsidies were too small but will have to make repayments if their subsidies were too high. We analyzed predicted repayments and refunds for people receiving subsidies, using California as a case study. We found that many families could owe large repayments to the Internal Revenue Service at their next tax filing. If income changes were reported and credits adjusted in a timely manner throughout the tax year, the number of filers owing repayments would be reduced by 7-41 percent and the median size of repayments reduced by as much as 61 percent (depending on the level of changes reported and the method used to adjust the subsidy amounts). We recommend that the health insurance exchanges mandated by the Affordable Care Act educate consumers about how the subsidies work and the need to promptly report income changes. We also recommend that they provide tools and assistance to determine the amount of subsidies that enrollees should take in advance.

Chemical Characterization of an Envelope B/D Sample from Hanford Tank 241-AZ-102

A sample from Hanford waste tank 241-AZ-102 was received at the Savannah River Technology Center (SRTC) and chemically characterized. The sample containing supernate and a small amount of sludge solids was analyzed as-received. The filtered supernatant liquid, the total dried solids of the sample, and the washed insoluble solids obtained from filtration of the sample were analyzed. A mass balance calculation of the three fractions of the sample analyzed indicate the analytical results appear relatively self-consistent for major components of the sample. However, some inconsistency was observed between results were more than one method of determination was employed and formore » species present in low concentrations. The actinides isotopes, plutonium, americium, and curium, present analytical challenges due to the low concentration of these species and the potential for introduction of small amounts of contamination during sampling handling resulting in large uncertainties. A direct comparison to previous analyses of material from tank 241-AZ-102 showed good agreement with the filtered supernatant liquid. However, the comparison of solids data showed poor agreement. The poor agreement shown between the current results for the solids samples and previous analyses most likely results from the uncertainties associated with obtaining small solids samples from a large non-homogenized waste tank.« less

Changes in Church-Based Social Support Relationships During Older Adulthood

Objectives. To track the course of age-related changes in emotional and tangible support given and received by older adults in the context of their religious congregations. Method. Hierarchical linear modeling was applied to data from a national sample of 1,192 White and African American older adults who attended church regularly, and they were interviewed up to four times over a period of seven years. Results. Changes were found in six measures of support. Participants increased in terms of the amount of emotional support that they both gave and received, whereas decreased in the amount of tangible support they gave and received. Satisfaction increased with age for both emotional and tangible support. There were large race-related differences, with African Americans being more engaged in support relationships of all types. Religious factors, including frequency of attendance, commitment, and the congregational cohesiveness were strong predictors of between-person differences. Discussion. This study is the first to demonstrate within-person change in church-based support relationships during the course of older adulthood. Patterns of increasing quantity and quality of emotional ties, but decreasing tangible support, partially contrast with previous findings regarding secular support networks but are consistent with the socioemotional selectivity perspective.

Big Science vs. Little Science: How Scientific Impact Scales with Funding.

PubMed

Fortin, Jean-Michel; Currie, David J

2013-01-01

is it more effective to give large grants to a few elite researchers, or small grants to many researchers? Large grants would be more effective only if scientific impact increases as an accelerating function of grant size. Here, we examine the scientific impact of individual university-based researchers in three disciplines funded by the Natural Sciences and Engineering Research Council of Canada (NSERC). We considered four indices of scientific impact: numbers of articles published, numbers of citations to those articles, the most cited article, and the number of highly cited articles, each measured over a four-year period. We related these to the amount of NSERC funding received. Impact is positively, but only weakly, related to funding. Researchers who received additional funds from a second federal granting council, the Canadian Institutes for Health Research, were not more productive than those who received only NSERC funding. Impact was generally a decelerating function of funding. Impact per dollar was therefore lower for large grant-holders. This is inconsistent with the hypothesis that larger grants lead to larger discoveries. Further, the impact of researchers who received increases in funding did not predictably increase. We conclude that scientific impact (as reflected by publications) is only weakly limited by funding. We suggest that funding strategies that target diversity, rather than "excellence", are likely to prove to be more productive.

Successful integration of ergonomics into continuous improvement initiatives.

PubMed

Monroe, Kimberly; Fick, Faye; Joshi, Madina

2012-01-01

Process improvement initiatives are receiving renewed attention by large corporations as they attempt to reduce manufacturing costs and stay competitive in the global marketplace. These initiatives include 5S, Six Sigma, and Lean. These programs often take up a large amount of available time and budget resources. More often than not, existing ergonomics processes are considered separate initiatives by upper management and struggle to gain a seat at the table. To effectively maintain their programs, ergonomics program managers need to overcome those obstacles and demonstrate how ergonomics initiatives are a natural fit with continuous improvement philosophies.

Characterization of Moving Dust Particles

Bos, Brent J.; Antonille, Scott R.; Memarsadeghi, Nargess

2010-01-01

A large depth-of-field Particle Image Velocimeter (PIV) has been developed at NASA GSFC to characterize dynamic dust environments on planetary surfaces. This instrument detects and senses lofted dust particles. We have been developing an autonomous image analysis algorithm architecture for the PIV instrument to greatly reduce the amount of data that it has to store and downlink. The algorithm analyzes PIV images and reduces the image information down to only the particle measurement data we are interested in receiving on the ground - typically reducing the amount of data to be handled by more than two orders of magnitude. We give a general description of PIV algorithms and describe only the algorithm for estimating the velocity of the traveling particles.

Transfer of interferon alfa into human breast milk.

2000-08-01

Originally assumed to be antiviral substances, the efficacy of interferons in a number of pathologies, including malignancies, multiple sclerosis, and other immune syndromes, is increasingly recognized. This study provides data on the transfer of interferon alfa (2B) into human milk of a patient receiving massive intravenous doses for the treatment of malignant melanoma. Following an intravenous dose of 30 million IU, the amount of interferon transferred into human milk was only slightly elevated (1551 IU/mL) when compared to control milk (1249 IU/mL). These data suggest that even following enormous doses, interferon is probably too large in molecular weight to transfer into human milk in clinically relevant amounts.

A New Culture of Transparency: Industry Payments to Orthopedic Surgeons.

Under the Physician Payments Sunshine Act, "payments or transfers of value" by biomedical companies to physicians must be disclosed through the Open Payments Program. Designed to provide transparency of financial transactions between medication and device manufacturers and health care providers, the Open Payments Program shows financial relationships between industry and health care providers. Awareness of this program is crucial because its interpretation or misinterpretation by patients, physicians, and the general public can affect patient care, clinical practice, and research. This study evaluated nonresearch payments by industry to orthopedic surgeons. A retrospective cross-sectional review of the first wave of Physician Payments Sunshine Act data (August through December 2013) was performed to characterize industry payments to orthopedic surgeons by subspecialty, amount, type, origin, and geographic distribution. During this 5-month period, orthopedic surgeons (n=14,828) received $107,666,826, which included 3% of those listed in the Open Payments Program and 23% of the total amount paid. Of orthopedic surgeons who received payment, 45% received less than $100 and 1% received $100,000 or more. Median payment (interquartile range) was $119 ($34-$636), and mean payment was $7261±95,887. The largest payment to an individual orthopedic surgeon was $7,849,711. The 2 largest payment categories were royalty or license fees (68%) and consulting fees (13%). During the study period, orthopedic surgeons had substantial financial ties to industry. Of orthopedic surgeons who received payments, the largest proportion (45%) received less than $100 and only 1% received large payments (≥$100,000). The Open Payments Program offers insight into industry payments to orthopedic surgeons. [Orthopedics. 2016; 39(6):e1058-e1062.]. Copyright 2016, SLACK Incorporated.

Silva, Melanie Lopes da; Castro, Rebeca Oliveira; Sales, Alessandro Souza; Araújo, Fábio Vieira de

2018-05-01

Arraial do Cabo, RJ, Brazil, is known as the diving capital due to its clear waters and great biodiversity, a consequence of the upwelling phenomenon. This feature attracts tourists tripling their population during holidays, causing increase in the amount of debris on beaches and waters endangering marine biodiversity. To evaluate the amount of solid waste found on beaches in two different holiday period, eight people in each beach collected macrodebris (≥2 cm) in a transect covering an 20 m wide area, during 20 min, in winter/2015 and summer/2017. The materials were weighed, quantified and characterized. In the summer, when the number of tourists is greater, a larger total amount of waste in units were found. Plastic and cigarette butts were the most abundant. The results show that the city does not have adequate planning to receive a large amount of tourists, being vulnerable to socioeconomic and environmental damages. Copyright © 2018 Elsevier Ltd.

POM Pulses: Characterizing the Physical and Chemical Properties of Particulate Organic Matter (POM) Mobilized by Large Storm Events and its Influence on Receiving Fluvial Systems

NASA Astrophysics Data System (ADS)

Johnson, E. R.; Rowland, R. D.; Protokowicz, J.; Inamdar, S. P.; Kan, J.; Vargas, R.

2016-12-01

Extreme storm events have tremendous erosive energy which is capable of mobilizing vast amounts of material from watershed sources into fluvial systems. This complex mixture of sediment and particulate organic matter (POM) is a nutrient source, and has the potential to impact downstream water quality. The impact of POM on receiving aquatic systems can vary not only by the total amount exported but also by the various sources involved and the particle sizes of POM. This study examines the composition of POM in potential sources and within-event POM by: (1) determining the amount and quality of dissolved organic matter (DOM) that can be leached from coarse, medium and fine particle classes; (2) assessing the C and N content and isotopic character of within-event POM; and (3) coupling physical and chemical properties to evaluate storm event POM influence on stream water. Storm event POM samples and source sediments were collected from a forested headwater catchment (second order stream) in the Piedmont region of Maryland. Samples were sieved into three particle classes - coarse (2mm-1mm), medium (1mm-250µm) and fine (<250µm). Extractions were performed for three particle class sizes and the resulting fluorescent organic matter was analyzed. Carbon (C) and Nitrogen (N) amount, C:N ratio, and isotopic analysis of 13C and 15N were performed on solid state event and source material. Future work will include examination of microbial communities associated with POM particle size classes. Physical size class separation of within-event POM exhibited differences in C:N ratios, δ15N composition, and extracted DOM lability. Smaller size classes exhibited lower C:N ratios, more enriched δ15N and more recalcitrant properties in leached DOM. Source material had varying C:N ratios and contributions to leached DOM. These results indicate that both source and size class strongly influence the POM contribution to fluvial systems during large storm events.

Impact of Swarm GPS receiver updates on POD performance

NASA Astrophysics Data System (ADS)

van den IJssel, Jose; Forte, Biagio; Montenbruck, Oliver

2016-05-01

The Swarm satellites are equipped with state-of-the-art Global Positioning System (GPS) receivers, which are used for the precise geolocation of the magnetic and electric field instruments, as well as for the determination of the Earth's gravity field, the total electron content and low-frequency thermospheric neutral densities. The onboard GPS receivers deliver high-quality data with an almost continuous data rate. However, the receivers show a slightly degraded performance when flying over the geomagnetic poles and the geomagnetic equator, due to ionospheric scintillation. Furthermore, with only eight channels available for dual-frequency tracking, the amount of collected GPS tracking data is relatively low compared with various other missions. Therefore, several modifications have been implemented to the Swarm GPS receivers. To optimise the amount of collected GPS data, the GPS antenna elevation mask has slowly been reduced from 10° to 2°. To improve the robustness against ionospheric scintillation, the bandwidths of the GPS receiver tracking loops have been widened. Because these modifications were first implemented on Swarm-C, their impact can be assessed by a comparison with the close flying Swarm-A satellite. This shows that both modifications have a positive impact on the GPS receiver performance. The reduced elevation mask increases the amount of GPS tracking data by more than 3 %, while the updated tracking loops lead to around 1.3 % more observations and a significant reduction in tracking losses due to severe equatorial scintillation. The additional observations at low elevation angles increase the average noise of the carrier phase observations, but nonetheless slightly improve the resulting reduced-dynamic and kinematic orbit accuracy as shown by independent satellite laser ranging (SLR) validation. The more robust tracking loops significantly reduce the large carrier phase observation errors at the geomagnetic poles and along the geomagnetic equator and do not degrade the observations at midlatitudes. SLR validation indicates that the updated tracking loops also improve the reduced-dynamic and kinematic orbit accuracy. It is expected that the Swarm gravity field recovery will benefit from the improved kinematic orbit quality and potentially also from the expected improvement of the kinematic baseline determination and the anticipated reduction in the systematic gravity field errors along the geomagnetic equator. Finally, other satellites that carry GPS receivers that encounter similar disturbances might also benefit from this analysis.

The human motor neuron pools receive a dominant slow‐varying common synaptic input

PubMed Central

Negro, Francesco; Yavuz, Utku Şükrü

2016-01-01

Key points Motor neurons in a pool receive both common and independent synaptic inputs, although the proportion and role of their common synaptic input is debated.Classic correlation techniques between motor unit spike trains do not measure the absolute proportion of common input and have limitations as a result of the non‐linearity of motor neurons.We propose a method that for the first time allows an accurate quantification of the absolute proportion of low frequency common synaptic input (<5 Hz) to motor neurons in humans.We applied the proposed method to three human muscles and determined experimentally that they receive a similar large amount (>60%) of common input, irrespective of their different functional and control properties.These results increase our knowledge about the role of common and independent input to motor neurons in force control. Abstract Motor neurons receive both common and independent synaptic inputs. This observation is classically based on the presence of a significant correlation between pairs of motor unit spike trains. The functional significance of different relative proportions of common input across muscles, individuals and conditions is still debated. One of the limitations in our understanding of correlated input to motor neurons is that it has not been possible so far to quantify the absolute proportion of common input with respect to the total synaptic input received by the motor neurons. Indeed, correlation measures of pairs of output spike trains only allow for relative comparisons. In the present study, we report for the first time an approach for measuring the proportion of common input in the low frequency bandwidth (<5 Hz) to a motor neuron pool in humans. This estimate is based on a phenomenological model and the theoretical fitting of the experimental values of coherence between the permutations of groups of motor unit spike trains. We demonstrate the validity of this theoretical estimate with several simulations. Moreover, we applied this method to three human muscles: the abductor digiti minimi, tibialis anterior and vastus medialis. Despite these muscles having different functional roles and control properties, as confirmed by the results of the present study, we estimate that their motor pools receive a similar and large (>60%) proportion of common low frequency oscillations with respect to their total synaptic input. These results suggest that the central nervous system provides a large amount of common input to motor neuron pools, in a similar way to that for muscles with different functional and control properties.

Volunteer Work in the Church Among Older Mexican Americans

Krause, Neal; Hayward, R. David

2012-01-01

The purpose of this study is to identify the factors that influence the amount of volunteer work that older Mexican Americans perform in the place where they worship. The relationship between religion and volunteering is viewed from a social identity perspective. Data from a nationally representative sample of older Mexican Americans suggest that Evangelical/Pentecostal church members spend more time performing volunteer work at church than older Mexican Americans who affiliate with other denominations. Moreover, the findings indicate that the difference in the amount of volunteering between the two groups can largely be explained by differences in the nature of the spiritual support that Evangelical/Pentecostal receive from their fellow church members as well as depth of their commitment to their faith.

Effects of Acute and Chronic Flunitrazepam on Delay Discounting in Pigeons

PubMed Central

Eppolito, Amy K; France, Charles P; Gerak, Lisa R

2011-01-01

Delay to delivery of a reinforcer can decrease responding for that reinforcer and increase responding for smaller reinforcers that are available concurrently and delivered without delay; acute administration of drugs can alter responding for large, delayed reinforcers, although the impact of chronic treatment on delay discounting is not well understood. In this experiment, the effects of repeated administration of the benzodiazepine flunitrazepam were studied in 6 pigeons responding on one key to receive food that was delivered immediately and on a second key to receive a larger amount of food that was delivered following delays which increased across a single session. Pigeons responded predominantly for the large reinforcer when there were no delays and when delays were short; however, as delays increased, responding for the large reinforcer decreased. Acutely, flunitrazepam (0.32, 1.0 and 3.2 mg/kg) dose-dependently increased responding for the large reinforcer, shifting the discounting curve rightward and upward. Repeated administration of flunitrazepam (0.32, 1.0 and 3.2 mg/kg, each for six sessions, separated by one session during which vehicle was administered) did not markedly alter its effects on responding for the large reinforcer, indicating that the development of tolerance to this effect of flunitrazepam is modest under these conditions.

1987-01-01

An iridium versus iridium-40% rhodium thermocouple was studied. Problems associated with the use of this thermocouple for high temperature applications (up to 2000 C) were investigated. The metallurgical studies included X-ray, macroscopic, resistance, and metallographic studies. The thermocouples in the as-received condition from the manufacturer revealed large amounts of internal stress caused by cold working during manufacturing. The thermocouples also contained a large amount of inhomogeneities and segregations. No phase transformations were observed in the alloy up to 1100 C. It was found that annealing the thermocouple at 1800 C for two hours, and then at 1400 C for 2 to 3 hours yielded a fine grain structure, relieving some of the strains, and making the wire more ductile. It was also found that the above annealing procedure stabilized the thermal emf behavior of the thermocouple for application below 1800 C (an improvement from + or - 1% to + or - 0.02% within the range of the test parameters used).

The National Offshore Wind Energy Grid Interconnection Study (NOWEGIS) considers the availability and potential impacts of interconnecting large amounts of offshore wind energy into the transmission system of the lower 48 contiguous United States. A total of 54GW of offshore wind was assumed to be the target for the analyses conducted. A variety of issues are considered including: the anticipated staging of offshore wind; the offshore wind resource availability; offshore wind energy power production profiles; offshore wind variability; present and potential technologies for collection and delivery of offshore wind energy to the onshore grid; potential impacts to existing utility systemsmore » most likely to receive large amounts of offshore wind; and regulatory influences on offshore wind development. The technologies considered the reliability of various high-voltage ac (HVAC) and high-voltage dc (HVDC) technology options and configurations. The utility system impacts of GW-scale integration of offshore wind are considered from an operational steady-state perspective and from a regional and national production cost perspective.« less

Long-term Effects of Organic Waste Fertilizers on Soil Structure, Tracer Transport, and Leaching of Colloids.

PubMed

Lekfeldt, Jonas Duus Stevens; Kjaergaard, Charlotte; Magid, Jakob

2017-07-01

Organic waste fertilizers have previously been observed to significantly affect soil organic carbon (SOC) content and soil structure. However, the effect of organic waste fertilizers on colloid dispersibility and leaching of colloids from topsoil has not yet been studied extensively. We investigated how the repeated application of different types of agricultural (liquid cattle slurry and solid cattle manure) and urban waste fertilizers (sewage sludge and composted organic household waste) affected soil physical properties, colloid dispersion from aggregates, tracer transport, and colloid leaching from intact soil cores. Total porosity was positively correlated with SOC content. Yearly applications of sewage sludge increased absolute microporosity (pores <30 μm) and decreased relative macroporosity (pores >30 μm) compared with the unfertilized control, whereas organic household waste compost fertilization increased both total porosity and the absolute porosity in all pore size classes (though not significant for 100-600 μm). Treatments receiving large amounts of organic fertilizers exhibited significantly lower levels of dispersible colloids compared with an unfertilized control and a treatment that had received moderate applications of cattle slurry. The content of water-dispersible colloids could not be explained by a single factor, but differences in SOC content, electrical conductivity, and sodium adsorption ratio were important factors. Moreover, we found that the fertilizer treatments did not significantly affect the solute transport properties of the topsoil. Finally, we found that the leaching of soil colloids was significantly decreased in treatments that had received large amounts of organic waste fertilizers, and we ascribe this primarily to treatment-induced differences in effluent electrical conductivity during leaching.

Algorithm for Aligning an Array of Receiving Radio Antennas

NASA Technical Reports Server (NTRS)

Rogstad, David

2006-01-01

A digital-signal-processing algorithm (somewhat arbitrarily) called SUMPLE has been devised as a means of aligning the outputs of multiple receiving radio antennas in a large array for the purpose of receiving a weak signal transmitted by a single distant source. As used here, aligning signifies adjusting the delays and phases of the outputs from the various antennas so that their relatively weak replicas of the desired signal can be added coherently to increase the signal-to-noise ratio (SNR) for improved reception, as though one had a single larger antenna. The method was devised to enhance spacecraft-tracking and telemetry operations in NASA's Deep Space Network (DSN); the method could also be useful in such other applications as both satellite and terrestrial radio communications and radio astronomy. Heretofore, most commonly, alignment has been effected by a process that involves correlation of signals in pairs. This approach necessitates the use of a large amount of hardware most notably, the N(N - 1)/2 correlators needed to process signals from all possible pairs of N antennas. Moreover, because the incoming signals typically have low SNRs, the delay and phase adjustments are poorly determined from the pairwise correlations. SUMPLE also involves correlations, but the correlations are not performed in pairs. Instead, in a partly iterative process, each signal is appropriately weighted and then correlated with a composite signal equal to the sum of the other signals (see Figure 1). One benefit of this approach is that only N correlators are needed; in an array of N much greater than 1 antennas, this results in a significant reduction of the amount of hardware. Another benefit is that once the array achieves coherence, the correlation SNR is N - 1 times that of a pair of antennas.

Willingness to use mobile application for smartphone for improving road safety.

Cardamone, Angelo Stephen; Eboli, Laura; Forciniti, Carmen; Mazzulla, Gabriella

2016-01-01

In the last few years mobile devices have reached a large amount of consumers in both developed and high-growth world economies. In 2013, 97% of the Italian population owns a mobile phone, and 62% owns a smartphone. Application software for mobile devices is largely proposed to consumers, and several mobile applications were oriented toward the improvement of road safety and road accident risk reduction. In this paper, we describe the results of a survey oriented to preventively investigate on the willingness to receive and/or to give information about road condition by means of mobile devices. Road users were informed about the characteristics of a mobile application, and then they were invited to complete a questionnaire. Experimental data were used for capturing road user attitudes toward the use of the smartphone to improve road safety, and to establish the preferences for the different features of the proposed mobile application. To this end, we choose to use the ordered probit model methodology. We demonstrate that the adopted methodology accounts for the differential impacts of the willingness to receive and/or to give information about road conditions on the overall willingness to receive and/or to give information through an application software for mobile devices.

Telemetry location error in a forested habitat

1989-01-01

The error associated with locations estimated by radio-telemetry triangulation can be large and variable in a hardwood forest. We assessed the magnitude and cause of telemetry location errors in a mature hardwood forest by using a 4-element Yagi antenna and compass bearings toward four transmitters, from 21 receiving sites. The distance error from the azimuth intersection to known transmitter locations ranged from 0 to 9251 meters. Ninety-five percent of the estimated locations were within 16 to 1963 meters, and 50% were within 99 to 416 meters of actual locations. Angles with 20o of parallel had larger distance errors than other angles. While angle appeared most important, greater distances and the amount of vegetation between receivers and transmitters also contributed to distance error.

Decision-making in state lotteries: half now or all of it later?

PubMed

Baker, Forest; Johnson, Matthew W; Bickel, Warren K

2003-12-01

Many state lotteries offer players a choice between receiving roughly half of the jackpot immediately and receiving the entire jackpot over 25 annual payments. This requires players to make a decision that involves uncertainty, delay, and large amounts of real money. Archival data on lottery players' jackpot payment decisions were collected from seven state and three multistate lotteries. Players' jackpot payment preferences were assessed at the time of ticket purchase and after winning a jackpot. Preference for the annuity payment option significantly decreased as jackpot size increased, both at the time of ticket purchase and after winning. Furthermore, a significant proportion of winners who selected the annuity payment option at ticket purchase switched to the cash payment option after winning, whereas no winners switched from the cash to the annuity option after winning. These findings suggest that real-world choices involving large sums of money may be subject to diminishing marginal utility and probability and delay discounting.

2010-05-01

To determine fluid retention, glomerular filtration rate, and urine output in dogs anesthetized for a surgical orthopedic procedure. 23 dogs treated with a tibial plateau leveling osteotomy. 12 dogs were used as a control group. Cardiac output was measured in 5 dogs, and 6 dogs received carprofen for at least 14 days. Dogs received oxymorphone, atropine, propofol, and isoflurane for anesthesia (duration, 4 hours). Urine and blood samples were obtained for analysis every 30 minutes. Lactated Ringer's solution was administered at 10 mL/kg/h. Urine output was measured and glomerular filtration rate was estimated. Fluid retention was measured by use of body weight, fluid balance, and bioimpedance spectroscopy. No difference was found among control, cardiac output, or carprofen groups, so data were combined. Median urine output and glomerular filtration rate were 0.46 mL/kg/h and 1.84 mL/kg/min. Dogs retained a large amount of fluids during anesthesia, as indicated by increased body weight, positive fluid balance, increased total body water volume, and increased extracellular fluid volume. The PCV, total protein concentration, and esophageal temperature decreased in a linear manner. Dogs anesthetized for a tibial plateau leveling osteotomy retained a large amount of fluids, had low urinary output, and had decreased PCV, total protein concentration, and esophageal temperature. Evaluation of urine output alone in anesthetized dogs may not be an adequate indicator of fluid balance.

2004-01-15

Porous compacts with both biological and biomechanical compatibilities and high strength were developed. Spherical powders of Ti-6Al-4V alloy, which were either as received or surface modified with the use of calcium ions by hydrothermal treatment (HTT), were fabricated by a spark plasma sintering process. The porous compacts of pure Ti were used as reference materials. Porosity was approximately 30%, and compressive strengths were 113 and 125 MPa for the as-received Ti alloy powders and those modified by the HTT process, respectively. The bending strength and elastic modulus of as-received Ti alloy powders were 128-178 MPa and 16-18 GPa, respectively. Each of the compacts was immersed in simulated body fluid (SBF). The amount of adsorption/precipitation of calcium phosphate through the compacts was measured by weight change and was observed by SEM. The compacts were covered with calcium phosphate after 2 weeks of immersion in SBF. The compacts of Ti alloy had plenty of precipitated apatite crystals, and modification by HTT accumulated more precipitation. Because calcium phosphate is a mineral component of bone, apatite, which is precipitated on the surface of the compacts, could adsorb proteins and/or drugs such as antibiotics. It is expected that a large amount of proteins and/or drugs could be impregnated when the porous compacts developed are used. Copyright 2003 Wiley Periodicals, Inc.

Creatine is essential for normal neural development; children with inborn errors of creatine synthesis or transport exhibit neurological symptoms such as mental retardation, speech delay and epilepsy. Creatine accretion may occur through dietary intake or de novo creatine synthesis. The objective of the present study was to determine how much creatine an infant must synthesise de novo. We have calculated how much creatine an infant needs to account for urinary creatinine excretion (creatine's breakdown product) and new muscle lay-down. To measure an infant's dietary creatine intake, we measured creatine in mother's milk and in various commercially available infant formulas. Knowing the amount of milk/formula ingested, we calculated the amount of creatine ingested. We have found that a breast-fed infant receives about 9 % of the creatine needed in the diet and that infants fed cows' milk-based formula receive up to 36 % of the creatine needed. However, infants fed a soya-based infant formula receive negligible dietary creatine and must rely solely on de novo creatine synthesis. This is the first time that it has been shown that neonatal creatine accretion is largely due to de novo synthesis and not through dietary intake of creatine. This has important implications both for infants suffering from creatine deficiency syndromes and for neonatal amino acid metabolism.

Plants receive volatile compounds emitted by neighboring plants that are infested by herbivores, and consequently the receiver plants begin to defend against forthcoming herbivory. However, to date, how plants receive volatiles and, consequently, how they fortify their defenses, is largely unknown. In this study, we found that undamaged tomato plants exposed to volatiles emitted by conspecifics infested with common cutworms (exposed plants) became more defensive against the larvae than those exposed to volatiles from uninfested conspecifics (control plants) in a constant airflow system under laboratory conditions. Comprehensive metabolite analyses showed that only the amount of (Z)-3-hexenylvicianoside (HexVic) was higher in exposed than control plants. This compound negatively affected the performance of common cutworms when added to an artificial diet. The aglycon of HexVic, (Z)-3-hexenol, was obtained from neighboring infested plants via the air. The amount of jasmonates (JAs) was not higher in exposed plants, and HexVic biosynthesis was independent of JA signaling. The use of (Z)-3-hexenol from neighboring damaged conspecifics for HexVic biosynthesis in exposed plants was also observed in an experimental field, indicating that (Z)-3-hexenol intake occurred even under fluctuating environmental conditions. Specific use of airborne (Z)-3-hexenol to form HexVic in undamaged tomato plants reveals a previously unidentified mechanism of plant defense. PMID:24778218

Multilevel UQ strategies for large-scale multiphysics applications: PSAAP II solar receiver

NASA Astrophysics Data System (ADS)

Jofre, Lluis; Geraci, Gianluca; Iaccarino, Gianluca

2017-06-01

Uncertainty quantification (UQ) plays a fundamental part in building confidence in predictive science. Of particular interest is the case of modeling and simulating engineering applications where, due to the inherent complexity, many uncertainties naturally arise, e.g. domain geometry, operating conditions, errors induced by modeling assumptions, etc. In this regard, one of the pacing items, especially in high-fidelity computational fluid dynamics (CFD) simulations, is the large amount of computing resources typically required to propagate incertitude through the models. Upcoming exascale supercomputers will significantly increase the available computational power. However, UQ approaches cannot entrust their applicability only on brute force Monte Carlo (MC) sampling; the large number of uncertainty sources and the presence of nonlinearities in the solution will make straightforward MC analysis unaffordable. Therefore, this work explores the multilevel MC strategy, and its extension to multi-fidelity and time convergence, to accelerate the estimation of the effect of uncertainties. The approach is described in detail, and its performance demonstrated on a radiated turbulent particle-laden flow case relevant to solar energy receivers (PSAAP II: Particle-laden turbulence in a radiation environment).

Financing for global health is a critical element of research and development. Innovations in new vaccines are critically dependent on research funding given the large sums required, however estimates of global research investments are lacking. We evaluate infectious disease research investments, focusing on immunology and vaccine research by UK research funding organisations. In 1997-2010, £2.6 billion were spent by public and philanthropic organisations, with £590 million allocated to immunology and vaccine research. Preclinical studies received the largest funding amount £505 million accounting for 85.6% of total investment. In terms of specific infection, "the big three" infections dominated funding: HIV received £127 million (21.5% of total), malaria received £59 million (10.0% of total) and tuberculosis received £36 million (6.0% of total). We excluded industry funding from our analysis, as open-access data were unavailable. A global investment surveillance system is needed to map and monitor funding and guide allocation of scarce resources. Copyright © 2013 The Authors. Published by Elsevier Ltd.. All rights reserved.

We aimed to identify projects and categorise them by pathogen, disease and position along the research and development value chain. Setting The UK. Participants Institutions that host and carry out infectious disease research. Primary and secondary outcome measures The total amount spent and number of studies with a focus on several different respiratory pathogens or diseases, and to correlate these against the global burden of disease; also the total amount spent and number of studies relating to the type of science, the predominant funder in each category and the mean and median award size. Results We identified 6165 infectious disease studies with a total investment of £2·6 billion. Respiratory research received £419 million (16.1%) across 1192 (19.3%) studies. The Wellcome Trust provided greatest investment (£135.2 million; 32.3%). Tuberculosis received £155 million (37.1%), influenza £80 million (19.1%) and pneumonia £27.8 million (6.6%). Despite high burden, there was relatively little investment in vaccine-preventable diseases including diphtheria (£0.1 million, 0.03%), measles (£5.0 million, 1.2%) and drug-resistant tuberculosis. There were 802 preclinical studies (67.3%) receiving £273 million (65.2%), while implementation research received £81 million (19.3%) across 274 studies (23%). There were comparatively few phase I–IV trials or product development studies. Global health research received £68.3 million (16.3%). Relative investment was strongly correlated with 2010 disease burden. Conclusions The UK predominantly funds preclinical science. Tuberculosis is the most studied respiratory disease. The high global burden of pneumonia-related disease warrants greater investment than it has historically received.

2011-02-01

We conducted comprehensive receiver function analyses for a large amount of high-quality broadband teleseismic waveforms data recorded at 19 China National Digital Seismic Network (CNDSN) stations deployed in Northeast China. An advanced H- κ domain search method was adopted to accurately estimate the crustal thickness and ν P/ ν S ratio. The crust has an average thickness of about 34.4 km. The thinnest crust occurs in the central region of Northeast China, while the thickest crust is beneath the Yanshan belt. The ν P/ ν S ratio is relatively uniform with an average of about 1.733. The highest ν P/ ν S ratio is found beneath the Changbaishan, likely associated with its volcanic activities. We found significant lateral heterogeneity beneath three stations CN2, MDJ, and MIH located along the Suolon suture from the back-zimuthal dependence of Moho depth. The velocity modeling from receiver functions indicated complicated Earth structure beneath these stations with large crust-mantle transition zone, noticeable velocity jump in upper mantle, and low velocity zone in middle crust. Dipping velocity interface in the crust with strike approximately parallel to the Suolon suture and down-dip to the south or southeast might explain the observed lateral heterogeneity.

Intercontinental ballistic missiles based in silos have become relatively vulnerable, at least in theory, to counter-force attacks. This theoretical vulnerability may not, in fact, be a serious practical concern; it is nonetheless troubling both to policy-makers and to the public. Furthermore, the present generation of ICBMs is aging (the Minuteman II single warhead missile will exceed its operational life-span early in the next decade) and significant restructuring of the ballistic missile force may well be necessary if a Strategic Arms Reduction Treaty (START) is signed. This paper compares several proposed schemes for modernizing the ICBM force. Because the rail-garrison MIRVdmore » mobile system is the least costly alternative to secure a large number of strategic warheads, it receives a comparatively large amount of attention.« less

Toward freedom from cancer pain in Japan.

PubMed

Otsuka, Kuniko; Yasuhara, Hajime

2007-01-01

Life expectancy in Japan is highest in the world. Cancer is the leading cause of mortality in Japan, accounting for about 30 percent of all deaths. Many Japanese cancer patients experience severe pain although they and their families hope to be pain free at the end of their lives. Toward that end, the consumption of morphine in Japan has increased markedly since 1989. The amount of morphine hydrochloride and morphine sulfate consumed in 2001 was 6.1 times that used in Japan in 1989. However, the amount of morphine consumed in Japan is still less than in other developed nations, and was only one-sixth of the amount used in Australia in 2001. As a result, many Japanese cancer patients experience potentially manageable cancer pain, largely because the amount of the drug used by doctors is insufficient for pain control. An increasing number of Japanese doctors now understand that their patients' quality of life is most important in end-of-life care and how to use the three step analgesic ladder of the World Health Organization (WHO). However, other doctors do not understand these issues sufficiently causing some patients to die without good pain control. Both the general population and some medical professionals misunderstand and have prejudice against the use of morphine. Patients often do not participate in decision making about medical treatment because of remaining paternalism in the relationship between Japanese doctors and patients. Thus, cancer pain management in Japan is not as effective as it can be and not all Japanese cancer patients receive appropriate management for their cancer pain. To improve outcomes for Japanese patients, it is necessary for health professional and social work students and practicing professionals to receive contemporary education including an introduction to palliative care and ethics.

Colloid Mobilization in a Fractured Soil during Dry-Wet Cycles: Role of Drying Duration and Flow Path Permeability.

PubMed

Mohanty, Sanjay K; Saiers, James E; Ryan, Joseph N

2015-08-04

In subsurface soils, colloids are mobilized by infiltrating rainwater, but the source of colloids and the process by which colloids are generated between rainfalls are not clear. We examined the effect of drying duration and the spatial variation of soil permeability on the mobilization of in situ colloids in intact soil cores (fractured and heavily weathered saprolite) during dry-wet cycles. Measuring water flux at multiple sampling ports at the core base, we found that water drained through flow paths of different permeability. The duration of antecedent drying cycles affected the amount of mobilized colloids, particularly in high-flux ports that received water from soil regions with a large number of macro- and mesopores. In these ports, the amount of mobilized colloids increased with increased drying duration up to 2.5 days. For drying durations greater than 2.5 days, the amount of mobilized colloids decreased. In contrast, increasing drying duration had a limited effect on colloid mobilization in low-flux ports, which presumably received water from soil regions with fewer macro- and mesopores. On the basis of these results, we attribute this dependence of colloid mobilization upon drying duration to colloid generation from dry pore walls and distribution of colloids in flow paths, which appear to be sensitive to the moisture content of soil after drying and flow path permeability. The results are useful for improving the understanding of colloid mobilization during fluctuating weather conditions.

Acute thyrotoxicosis secondary to destructive thyroiditis associated with cardiac catheterization contrast dye.

PubMed

Calvi, Laura; Daniels, Gilbert H

2011-04-01

Thyrotoxicosis caused by destructive thyroiditis is self-limited and results from the subacute release of preformed thyroid hormone. Common etiologies include painful subacute thyroiditis and silent (painless) subacute thyroiditis (including postpartum thyroiditis, amiodarone-associated destructive thyroiditis, and lithium-associated thyroiditis). Thyrotoxicosis commonly evolves slowly over a matter of weeks. We report a unique case of severe thyrotoxicosis caused by acute- onset painful destructive thyroiditis in a patient who received large amounts of nonionic contrast dye Hexabrix® for cardiac catheterization. The results of thyroid function and physical examination were normal before the catheterization. The acute onset of severe thyroid pain, rapid increase in serum Free Thyroxine Index, and thyroglobulin concentrations with a triiodothyronine to free thyroxine index ratio of < 20 to 1 were compatible with an acute onset destructive thyroiditis, likely related to direct toxicity from the iodinated contrast material. In light of the large number of patients who receive these contrast agents during cardiac catheterization, clinicians should be advised of this potentially serious complication, particularly in the setting of unstable cardiac disease.

High-Degree Neurons Feed Cortical Computations

Timme, Nicholas M.; Ito, Shinya; Shimono, Masanori; Yeh, Fang-Chin; Litke, Alan M.; Beggs, John M.

2016-01-01

Recent work has shown that functional connectivity among cortical neurons is highly varied, with a small percentage of neurons having many more connections than others. Also, recent theoretical developments now make it possible to quantify how neurons modify information from the connections they receive. Therefore, it is now possible to investigate how information modification, or computation, depends on the number of connections a neuron receives (in-degree) or sends out (out-degree). To do this, we recorded the simultaneous spiking activity of hundreds of neurons in cortico-hippocampal slice cultures using a high-density 512-electrode array. This preparation and recording method combination produced large numbers of neurons recorded at temporal and spatial resolutions that are not currently available in any in vivo recording system. We utilized transfer entropy (a well-established method for detecting linear and nonlinear interactions in time series) and the partial information decomposition (a powerful, recently developed tool for dissecting multivariate information processing into distinct parts) to quantify computation between neurons where information flows converged. We found that computations did not occur equally in all neurons throughout the networks. Surprisingly, neurons that computed large amounts of information tended to receive connections from high out-degree neurons. However, the in-degree of a neuron was not related to the amount of information it computed. To gain insight into these findings, we developed a simple feedforward network model. We found that a degree-modified Hebbian wiring rule best reproduced the pattern of computation and degree correlation results seen in the real data. Interestingly, this rule also maximized signal propagation in the presence of network-wide correlations, suggesting a mechanism by which cortex could deal with common random background input. These are the first results to show that the extent to which a neuron modifies incoming information streams depends on its topological location in the surrounding functional network. PMID:27159884

An integral sunshade for optical reception antennas

NASA Technical Reports Server (NTRS)

Kerr, E. L.

1988-01-01

Optical reception antennas (telescopes) must be capable of receiving communications even when the deep-space laser source is located within a small angle of the Sun. Direst sunlight must not be allowed to shine on the primary reflector of an optical reception antenna, because too much light would be scattered into the signal detectors. A conventional sunshade that does not obstruct the antenna aperture would have to be about five times longer than its diameter in order to receive optical communications at a solar elongation of 12 degrees without interference. Such a long sunshade could not be accommodated within the dome of any existing large-aperture astronomical facility, and providing a new dome large enough would be prohibitively expensive. It is also desirable to reduce the amount of energy a space-based large-aperture optical reception facility would expend orienting a structure with such a sizable moment of inertia. Since a large aperture optical reception antenna will probably have a hexagonally segmented primary reflector, a sunshade consisting of hexagonal tubes can be mounted in alignment with the segmentation without producing any additional geometric obstruction. An analysis of the duration and recurrence of solar-conjunction communications outages (caused when a deep-space probe near an outer planet appears to be closer to the Sun than a given minimum solar elongation), and the design equations for the integral sunshade are appended.

Impact of Medicare on the Use of Medical Services by Disabled Beneficiaries, 1972-1974

PubMed Central

Deacon, Ronald W.

1979-01-01

The extension of Medicare coverage in 1973 to disabled persons receiving cash benefits under the Social Security Act provided an opportunity to examine the impact of health insurance coverage on utilization and expenses for Part B services. Data on medical services used both before and after coverage, collected through the Current Medicare Survey, were analyzed. Results indicate that access to care (as measured by the number of persons using services) increased slightly, while the rate of use did not. The large increase in the number of persons eligible for Medicare reflected the large increase in the number of cash beneficiaries. Significant increases also were found in the amount charged for medical services. The absence of large increases in access and service use may be attributed, in part, to the already existing source of third party payment available to disabled cash beneficiaries in 1972, before Medicare coverage.

2014-12-01

To explore the influence of pocket money on Dental Caries and Body Mass Index. A cross-sectional study was conducted wherein urban adolescent schoolchildren of age 13-18(n=916) were selected by two stage random sampling technique. Dental caries was measured using the DMFT Index. The children's nutritional status was assessed by means of anthropometric measurements. Body Mass Index using weight and height of children was evaluated using the reference standard of the WHO 2007. RESULTS showed that 50% of children receive pocket money from parents. The average amount received was Rs. 360/month. There was a significant correlation between age and amount of money received (r=0.160, p=.001). The average amount received by male children was significantly higher (Rs. 400) when compared to female children (Rs. 303). It was observed that income of the family (>30,000 Rs./month) and socioeconomic status (Upper class) was significantly dependent on the amount of money received by children (p<0.05). There was no significant difference in the occurrence of caries among children receiving pocket money or not. When BMI categories and pocket money were considered, statistically significant difference was seen among overweight and obese and normal weight children (p<.05). Higher proportion (40.1%) of overweight and obese adolescent children frequented the fast food restaurants every week when compared to the underweight (31.7%) and normal weight children (29.9%). Adolescent children receiving pocket money from parents could influence their eating habits in turn affect general health. Parents and teachers should motivate children on healthy spending of their pocket money.

Ego depletion decreases trust in economic decision making

Ainsworth, Sarah E.; Baumeister, Roy F.; Vohs, Kathleen D.; Ariely, Dan

2014-01-01

Three experiments tested the effects of ego depletion on economic decision making. Participants completed a task either requiring self-control or not. Then participants learned about the trust game, in which senders are given an initial allocation of $10 to split between themselves and another person, the receiver. The receiver receives triple the amount given and can send any, all, or none of the tripled money back to the sender. Participants were assigned the role of the sender and decided how to split the initial allocation. Giving less money, and therefore not trusting the receiver, is the safe, less risky response. Participants who had exerted self-control and were depleted gave the receiver less money than those in the non-depletion condition (Experiment 1). This effect was replicated and moderated in two additional experiments. Depletion again led to lower amounts given (less trust), but primarily among participants who were told they would never meet the receiver (Experiment 2) or who were given no information about how similar they were to the receiver (Experiment 3). Amounts given did not differ for depleted and non-depleted participants who either expected to meet the receiver (Experiment 2) or were led to believe that they were very similar to the receiver (Experiment 3). Decreased trust among depleted participants was strongest among neurotics. These results imply that self-control facilitates behavioral trust, especially when no other cues signal decreased social risk in trusting, such as if an actual or possible relationship with the receiver were suggested.

Eating like you are overweight: the effect of overweight models on food intake in a remote confederate study.

PubMed

Robinson, Eric; Sharps, Maxine; Price, Nicola; Dallas, Rebecca

2014-11-01

There is consistent evidence that people model the eating behaviour of others. The extent to which people model the amount of food consumed by other people of different weight statuses has received less attention. Here we tested the effect on food consumption of exposing female participants to information about the food consumption of either normal/healthy weight or overweight individuals. Eighty female participants took part in a between-subjects experiment, in which we used a remote-confederate design and manipulated whether participants saw intake information about normal/healthy weight or overweight previous participants (remote confederates). Regardless of the weight-status of the remote confederates, participants ate more food when they believed that previous participants had eaten a large amount of food, in comparison with when they believed previous participants had eaten a smaller amount of food. These findings indicate that women may model the food intake of other women, even when they believe they are of a different weight status to themselves. Copyright © 2014 Elsevier Ltd.

Altered trait variability in response to size-selective mortality.

PubMed

Uusi-Heikkilä, Silva; Lindström, Kai; Parre, Noora; Arlinghaus, Robert; Alós, Josep; Kuparinen, Anna

2016-09-01

Changes in trait variability owing to size-selective harvesting have received little attention in comparison with changes in mean trait values, perhaps because of the expectation that phenotypic variability should generally be eroded by directional selection typical for fishing and hunting. We show, however, that directional selection, in particular for large body size, leads to increased body-size variation in experimentally harvested zebrafish (Danio rerio) populations exposed to two alternative feeding environments: ad libitum and temporarily restricted food availability. Trait variation may influence population adaptivity, stability and resilience. Therefore, rather than exerting selection pressures that favour small individuals, our results stress the importance of protecting large ones, as they can harbour a great amount of variation within a population, to manage fish stocks sustainably. © 2016 The Author(s).

Adherence to oral rehydration therapy among in-patient children aged 1-59 months with some or no dehydration.

2010-04-01

To determine adherence to oral rehydration solution (ORS) among in-patients aged 1-59 months suffering from gastroenteritis and having some dehydration (SD) or no dehydration (ND) in two rural hospitals in Kenya. Children aged 1-59 months suffering from acute gastroenteritis with (SD) or (ND) were enrolled into the study, examined and medical records reviewed. On the second and third day of follow up, children were re-examined to ascertain hydration status and care-takers interviewed. Ninety-nine children were enrolled. Forty-five (75%) of the 60 children with SD received a correct prescription for ORS but only 12 (20%) received the correct amount. Among the 39 children with ND, 23 (59%) received a correct prescription for ORS, however only 16 (41%) received the correct amount. On the 3rd day, 9 (15%) of the 60 children with SD at baseline and 2 (5%) of the 39 with ND were classified as having SD. Four in five children with SD and 6 in 10 children with ND fail to receive the correct amounts of ORS.

Detection of Seasonal Changes in the Cryosphere Using Reflected GNSS Signals

NASA Astrophysics Data System (ADS)

Chew, C. C.; Zuffada, C.; Mannucci, A. J.; Lowe, S.; Oveisgharan, S.; Esterhuizen, S. X.

2016-12-01

Using ground-reflected GPS or GNSS signals in a bistatic radar approach is a new way of observing changes in the Earth's surface. Numerous studies using GNSS receivers flown on aircraft or mounted on towers have shown that these forward-scattered signals are sensitive to changes in sea state, soil moisture, vegetation cover, and sea ice. However, until last year, there was a paucity of observations from which to understand potential science applications from the vantage point of space. Two recent advancements have provided the largest amount of spaceborne reflection data ever recorded. The first, TechDemoSat-1 (TDS-1), is an experimental platform launched in July 2014 that houses a GPS receiver and antenna capable of recording reflections. Although designed to record reflections over the ocean surface, TDS-1 has also recorded a large amount of reflection data over land, which show sensitivity to both soil moisture and sea ice. The second major advancement is GNSS reflections data recorded by the SMAP radar receiver. JPL retuned the receiver to the GPS frequency soon after July 2015 and began passively recording reflections data. As of August 2016, the receiver is still recording daily reflections. Together, these two new sources of data allow the investigation of seasonal changes in the Earth's surface at moderately high resolution ( 1 km). Here, we present seasonal changes in the cryosphere as observed by TDS-1 and in the SMAP reflections data. Although the sensitivity to sea ice has been previously shown, here we show for the first time a strong change in the reflected signal over land between winter and the spring thaw of up to 15 dB. This could be an indication that reflected GNSS signals are sensitive to freeze/thaw state of the soil. The confounding influence of the snowpack on the signal must be understood before definitive conclusions can be made, and we show the current status of this analysis.

Gas ultrasonic flow rate measurement through genetic-ant colony optimization based on the ultrasonic pulse received signal model

NASA Astrophysics Data System (ADS)

Hou, Huirang; Zheng, Dandan; Nie, Laixiao

2015-04-01

For gas ultrasonic flowmeters, the signals received by ultrasonic sensors are susceptible to noise interference. If signals are mingled with noise, a large error in flow measurement can be caused by triggering mistakenly using the traditional double-threshold method. To solve this problem, genetic-ant colony optimization (GACO) based on the ultrasonic pulse received signal model is proposed. Furthermore, in consideration of the real-time performance of the flow measurement system, the improvement of processing only the first three cycles of the received signals rather than the whole signal is proposed. Simulation results show that the GACO algorithm has the best estimation accuracy and ant-noise ability compared with the genetic algorithm, ant colony optimization, double-threshold and enveloped zero-crossing. Local convergence doesn’t appear with the GACO algorithm until -10 dB. For the GACO algorithm, the converging accuracy and converging speed and the amount of computation are further improved when using the first three cycles (called GACO-3cycles). Experimental results involving actual received signals show that the accuracy of single-gas ultrasonic flow rate measurement can reach 0.5% with GACO-3 cycles, which is better than with the double-threshold method.

Responses to Oxidative and Heavy Metal Stresses in Cyanobacteria: Recent Advances

PubMed Central

Cassier-Chauvat, Corinne; Chauvat, Franck

2014-01-01

Cyanobacteria, the only known prokaryotes that perform oxygen-evolving photosynthesis, are receiving strong attention in basic and applied research. In using solar energy, water, CO2 and mineral salts to produce a large amount of biomass for the food chain, cyanobacteria constitute the first biological barrier against the entry of toxics into the food chain. In addition, cyanobacteria have the potential for the solar-driven carbon-neutral production of biofuels. However, cyanobacteria are often challenged by toxic reactive oxygen species generated under intense illumination, i.e., when their production of photosynthetic electrons exceeds what they need for the assimilation of inorganic nutrients. Furthermore, in requiring high amounts of various metals for growth, cyanobacteria are also frequently affected by drastic changes in metal availabilities. They are often challenged by heavy metals, which are increasingly spread out in the environment through human activities, and constitute persistent pollutants because they cannot be degraded. Consequently, it is important to analyze the protection against oxidative and metal stresses in cyanobacteria because these ancient organisms have developed most of these processes, a large number of which have been conserved during evolution. This review summarizes what is known regarding these mechanisms, emphasizing on their crosstalk. PMID:25561236

Central Neuraxial Blockade-Assisted External Cephalic Version in Reducing Caesarean Section Rate: Systematic Review and Meta-Analysis

PubMed Central

Bolaji, Ibrahim; Alabi-Isama, Lillian

2009-01-01

We review the medical literature on the success, safety and economic value of central neuraxial blockade-assisted (CNB) external cephalic version from randomized controlled studies identified from 1951 to 2009. The result showed that more women had successful ECV with regional anaesthesia with corresponding reduction in caesarean section rate. They were 1.5 times more likely than women not receiving anaesthesia to have a successful ECV. The number to treat is six women needed to receive anaesthesia for 1 baby to be turned from breech to cephalic presentation. Feto-maternal morbidity was not increased in the CNB-aided group consisting of only transient bradycardia. Although the appropriate amount of force for safe version has not been quantified, there was no report of uterine rupture despite removal of these patients from “excessive force-pain biofeedback loop” induced through motor nerve blockade. We can attribute 30% of cost savings amounting to £42,150.00 directly to CNB using the most up to date Health Resource Group Code (HRG4). The initial results are encouraging but until the benefits and safety of CNB-aided ECV are substantiated by large randomized, blinded controlled trials, this practice cannot be universally recommended.

No systematic study has focused on the characteristics and outcome of acute clozapine intoxication, although clozapine is the most widely used antipsychotic agent in China. The study reported herein examined the features of clozapine intoxication and the therapeutic effect of hemoperfusion (HP). In a retrospective chart review, the notes of 47 patients who attempted suicide by ingesting large amounts of clozapine and were treated at the only psychiatric emergency service in Beijing were analyzed. Of the 20 unconscious patients with plasma clozapine concentrations of more than 2000 ng/mL, 14 received a combination of HP and symptomatic treatment, whereas the other 6 and the remaining 27 patients received only symptomatic treatment. Patients' psychiatric conditions and both plasma clozapine and norclozapine concentrations were closely monitored and registered. One patient died of pulmonary edema and subsequent heart failure, but the rest of the patients recovered without any sequelae. Patients who received HP regained consciousness significantly faster than their counterparts with the same level of clozapine plasma concentration (>2000 ng/mL) who did not receive HP. A combination of HP and symptomatic treatment is the best therapeutic option when plasma clozapine concentration is high.

The performance of Geiger mode avalanche photo-diodes in free space laser communication links

NASA Astrophysics Data System (ADS)

Farrell, Thomas C.

2018-05-01

Geiger mode avalanche photo-diode (APD) arrays, when used as detectors in laser communication (lasercom) receivers, promise better performance at lower signal levels than APDs operated in the linear mode. In this paper, we describe the basic operation of the Geiger mode APD array as a lasercom detector, concentrating on aspects relevant to the link design engineer (rather than, for example, describing the details of the physics of the basic device operation itself). Equations are developed that describe the effects of defocus and hold-off time on the relation between the number of photons detected by the array and the output of photo-electron counts. We show how to incorporate these equations into a link budget. The resulting predictions are validated by comparison against simulation results. Finally, we compare the performance of linear mode APD based receivers and Geiger mode APD array based receivers. Results show the Geiger mode receivers yield better performance, in terms of probability of bit error, at lower signal levels, except on links where there is an exceptionally large amount of background noise. Under those conditions, not surprisingly, the hold-off time degrades performance.

Distribution and biokinetic analysis of 210Pb and 210Po in poultry due to ingestion of dicalcium phosphate.

Dicalcium phosphate (DCP) is used as a calcium supplement for food producing animals (i.e., cattle, poultry and pig). When DCP is produced via wet acid digestion of the phosphate rock and depending on the acid used in the industrial process, the final product can result in enhanced (210)Pb and (210)Po specific activities (approximately 2000 Bq.kg(-1)). Both (210)Pb and (210)Po are of great interest because their contribution to the dose received by ingestion is potentially large. The aims of this work are to examine the accumulation of (210)Pb and (210)Po in chicken tissues during the first 42 days of life and to build a suitable single-compartment biokinetic model to understand the behavior of both radionuclides within the entire animal using the experimental results. Three commercial corn-soybean-based diets containing different amounts and sources of DCP were fed to broilers during a period of 42 days. The results show that diets containing enhanced concentrations of (210)Pb and (210)Po lead to larger specific accumulation in broiler tissues compared to the blank diet. Radionuclides do not accumulate homogeneously within the animal body: (210)Pb follows the calcium pathways to some extent and accumulates largely in bones, while (210)Po accumulates to a large extent in liver and kidneys. However, the total amount of radionuclide accumulation in tissues is small compared to the amounts excreted in feces. The single-compartment non-linear biokinetic model proposed here for (210)Pb and (210)Po in the whole animal takes into account the size evolution and is self-consistent in that no fitting parameterization of intake and excretions rates is required.

Breastfeeding Problems Following Anesthetic Administration

PubMed Central

Howie, William O.; McMullen, Patricia C.

2006-01-01

Research literature supports the notion that maternal comfort should be considered a priority and that mothers should receive adequate information regarding any drug prior to receiving that drug. Some studies indicate that difficulties with breastfeeding may be related to the amount of the anesthetic or analgesic that is administered to the mother. Thus, it seems wise to administer the lowest possible dose to the mother in order to minimize the amount of drug (or metabolite) exposure to the nursing infant. Infant exposure can be further reduced if breastfeeding is avoided during the times when the mother receives high doses of anesthetics and analgesics. However, because relatively small amounts of the drug are excreted into the breast milk, some mothers may opt to continue nursing after weighing the benefits of breastfeeding against the potential risk to the infant. Others may choose to “pump and dump” breast milk while they receive anesthetic or analgesic agents. Any concerns in this regard should be discussed with the anesthesia provider, preferably prior to labor or to any surgeries while breastfeeding. PMID:17541461

Xu, Ning; Gruber, Margaret; Westcott, Neil; Soroka, Julie; Parkin, Isobel; Hegedus, Dwayne

2005-01-01

A new method has been developed for the extraction of volatiles from plant materials and tested on seedling tissue and mature leaves of Arabidopsis thaliana, pine needles and commercial mixtures of plant volatiles. Volatiles were extracted with n-pentane and then subjected to quick distillation at a moderate temperature. Under these conditions, compounds such as pigments, waxes and non-volatile compounds remained undistilled, while short-chain volatile compounds were distilled into a receiving flask using a high-efficiency condenser. Removal of the n-pentane and concentration of the volatiles in the receiving flask was carried out using a Vigreux column condenser prior to GC-MS. The method is ideal for the rapid extraction of low-boiling-point volatiles from small amounts of plant material, such as is required when conducting metabolic profiling or defining biological properties of volatile components from large numbers of mutant lines.

The experimental production of combination forms of virus. II. A study of serial passage in the allantoic sac of agents that combine the antigens of two distinct influenza A strains.

PubMed

HIRST, G K; GOTLIEB, T

1953-07-01

Double infection of the allantoic sac with Melbourne and WSN viruses induced the formation of a combination virus, which had some of the antigenic properties of both parents and which maintained itself through serial passage in the chorioallantoic sac. In the course of prolonged passage in the egg, three varieties of combination virus were found. The first (X(1)) occurred in ten passages and was characterized as follows: X(1) was produced in and could be successfully passed from those chick embryos that had received very large inocula of virus. The X(1) hemagglutinin was efficiently inhibited by both M and W antisera. Each passage fluid, containing X(1) as the predominant strain, also contained large amounts of the parent forms M and W. It is very likely that X(1) reverted to parent types of virus at a high rate. The second variety (X(2)) arose from the passage series of X(1) and was carried for approximately 20 passages without definite alteration in its character. It differed from X(1) in that it had the ability to appear as the predominant form occasionally in embryos that had received a limiting infective dilution of virus. Because of this, it seems probable that X(2) reverted to parent types at a slower rate than X(1). Like X(1), this virus was never obtained in pure form and suspensions in which it predominated contained large amounts of M and W, especially the former. Good evidence was obtained that X(2) reverted to M and W virus while multiplying in the chorioallantoic sac. X(3) was derived from passage of X(2) virus after 32 transfers and can be characterized in several ways: (a) X(3) yielded the only X(3) fluids on passage in eggs. This was in striking contrast to X(2) which could not be passed without giving rise to some fluids in which M and W predominated, (b) The X(3) hemagglutinin was weakly inhibited by all but the highest concentrations of M serum, but was strongly inhibited by W serum. X(2) was readily inhibited by relatively small amounts of both sera. (c) X(3) virus, after several passages at limiting dilutions, was neutralized to a highly significant degree by specific M and W sera. This is not necessarily an essential difference from the behavior of X(2) since technical difficulties (large amounts of M and W in X(2) fluids) may have prevented the demonstration of equally striking double neutralization of this virus, (d) After five limiting dilution passages, the X(3) virus retained the characteristics listed under (a) to (c). It is felt that the foregoing facts justify the conclusion that X(3) is a stable virus which combines some of the specific antigens of two parent types.

The aim of the present study was to assess the nutritional status and growth of medically fragile children receiving long-term enteral nutritional support (ENS). A retrospective cross-sectional survey was conducted at a tertiary-level pediatric hospital. Growth features and nutritional intake of children (n = 287) receiving ENS were evaluated. During a period of 5 years (2009-2013), study patients in the age group of 1 to 36 months had been referred for the explicit reason of tube weaning. Data were documented with the help of ARCHIMED (version 46.2) and analyzed using SPSS for Windows version 21. Nutritional/growth status was determined by using World Health Organization growth standard tables. Anthropometric parameters of children were compared with World Health Organization standards, and the prevalence of underweight, wasting, and stunting was very high despite being exclusively or predominantly on ENS. Results revealed that the age of a child, inadequate amount of caloric supply/day, the diagnosis of small-for-gestational age, and the type of tube (nasogastric tube) were significantly associated with growth/nutritional status (P < 0.05). Duration of ENS in the percentage of the cohort's lifetime and the main diagnosis were not associated with nutritional/growth outcomes. In medically fragile children, ENS does not ensure adequate growth per se. ENS requires highly specialized and individually tailored management and in many cases regular adjustments. Long-term tube feeding plans often seem unable to ensure the required amount of nutritional support, which surely compromise the individual efficacy of ENS.

A Diagnostic System for Studying Energy Partitioning and Assessing the Response of the Ionosphere during HAARP Modification Experiments

This research program focused on the construction of several key radio wave diagnostics in support of the HF Active Auroral Ionospheric Research Program (HAARP). Project activities led to the design, development, and fabrication of a variety of hardware units and to the development of several menu-driven software packages for data acquisition and analysis. The principal instrumentation includes an HF (28 MHz) radar system, a VHF (50 MHz) radar system, and a high-speed radar processor consisting of three separable processing units. The processor system supports the HF and VHF radars and is capable of acquiring very detailed data with large incoherent scatter radars. In addition, a tunable HF receiver system having high dynamic range was developed primarily for measurements of stimulated electromagnetic emissions (SEE). A separate processor unit was constructed for the SEE receiver. Finally, a large amount of support instrumentation was developed to accommodate complex field experiments. Overall, the HAARP diagnostics are powerful tools for studying diverse ionospheric modification phenomena. They are also flexible enough to support a host of other missions beyond the scope of HAARP. Many new research programs have been initiated by applying the HAARP diagnostics to studies of natural atmospheric processes.

2002-06-01

In a conflict test based on the rat's choice between an immediate punished reinforcer or a delayed nonpunished reinforcer, anxiolytic drugs increase the number of immediate punished reinforcers. In this study, two hypotheses were tested: first, during late proestrus or during midpregnancy, female rats will display an elevated amount of immediate punished reinforcers; second, ovariectomized rats will display an elevated amount of immediate punished reinforcers when they receive anxiolytic doses of neurosteroids. Thus, female rats (n = 15) were tested repeatedly during late proestrus, diestrus, and pregnancy in the aforementioned conflict task. They displayed an elevated amount of immediate punished reinforcers during late proestrus (P < .05) and during the 14th (P < .05) and 17th (P < .05) days of pregnancy compared to diestrus or 3rd, 7th, or 20th days of pregnancy. Likewise, ovariectomized rats (n = 90) displayed an elevated amount of immediate punished reinforcers compared to control rats only when they received anxiolytic doses of progesterone (1.0-2.0 mg/kg, P < .05) or allopregnanolone (1.0-2.0 mg/kg, P < .05). In conclusion, female rats displayed reduced conflict behavior during late proestrus and pregnancy, or after received anxiolytic doses of neurosteroids.

Middle-Aged Couples' Exchanges of Support with Aging Parents: Patterns and Association with Marital Satisfaction

We examined the context of intergenerational support exchanges with aging parents and its association with middle-aged couples' marital satisfaction. A sample of 197 middle-aged couples reported support they gave to and received from their parents (n = 440). Results indicated that couples provided more total support to and received more from their parents as a function of number of living parents, but the amount of support each parent received (‘parent-adjusted support’) was lower when there were more living parents. The amount of support given to and received from parents had no association with the couple's marital satisfaction, but discrepancies in support given to and received from parents did have a significant association with marital satisfaction. Husbands who gave more support to their living parent(s) than their wives reported lower marital satisfaction. A similar effect on marital satisfaction was found for wives who gave more support to their living parents than their husbands. These findings contrast with caregiving studies where amount of support affected marital satisfaction and suggest that inequalities in involvement with parents may be a critical dimension in marriages of midlife adults.

A capillary electrophoresis system comprises capillaries positioned in parallel to each other forming a plane. The capillaries are configured to allow samples to migrate. A light source is configured to illuminate the capillaries and the samples therein. This causes the samples to emit light. A lens is configured to receive the light emitted by the samples and positioned directly over a first group of the capillaries and obliquely over a second group of the capillaries. The light source is further configured to illuminate the second group of capillaries more than the first group of the capillaries such that amount of light received by the lens from the first group of capillaries is substantially identical to amount of light received from the second group of capillaries when an identical amount of the samples is migrating through the first and second group capillaries.

Complete physico-chemical treatment for coke plant effluents.

2002-03-01

Naturally found coal is converted to coke which is suitable for metallurgical industries. Large quantities of liquid effluents produced contain a large amount of suspended solids, high COD, BOD, phenols, ammonia and other toxic substances which are causing serious pollution problem in the receiving water to which they are discharged. There are a large number of coke plants in the vicinity of Jharia Coal Field (JCF). Characteristics of the effluents have been evaluated. The present effluent treatment systems were found to be inadequate. Physico-chemical treatment has been considered as a suitable option for the treatment of coke plant effluents. Ammonia removal by synthetic zeolite, activated carbon for the removal of bacteria, viruses, refractory organics, etc. were utilized and the results are discussed. A scheme has been proposed for the complete physico-chemical treatment, which can be suitably adopted for the recycling, reuse and safe disposal of the treated effluent. Various unit process and unit operations involved in the treatment system have been discussed. The process may be useful on industrial scale at various sites.

Influence of dietary fiber on luminal environment and morphology in the small and large intestine of sows.

2008-09-01

In this study, the effect of feeding different types and amounts of dietary fiber (DF) on luminal environment and morphology in the small and large intestine of sows was studied. Three diets, a low-fiber diet (LF) and 2 high-fiber diets (high fiber 1, HF1, and high fiber 2, HF2) were used. Diet LF (DF, 17%; soluble DF 4.6%) was based on wheat and barley, whereas the 2 high-fiber diets (HF1: DF, 43%; soluble DF, 11.0%; and HF2: DF, 45%; soluble DF, 7.6%) were based on wheat and barley supplemented with different coproducts from the vegetable food and agroindustry (HF1 and HF2: sugar beet pulp, potato pulp, and pectin residue; HF2: brewers spent grain, seed residue, and pea hull). The diets were fed for a 4-wk period to 12 sows (4 receiving each diet). Thereafter, the sows were killed 4 h postfeeding, and digesta and tissue samples were collected from various parts of the small and large intestine. The carbohydrates in the LF diet were well digested in the small intestine, resulting in less digesta in all segments of the intestinal tract. The fermentation of nonstarch polysaccharides in the large intestine was affected by the chemical composition and physicochemical properties. The digesta from pigs fed the LF diet provided low levels of fermentable carbohydrates that were depleted in proximal colon, whereas for pigs fed the 2 high-DF diets, the digesta was depleted of fermentable carbohydrates at more distal locations of the colon. The consequence was an increased retention time, greater DM percentage, decreased amount of material, and a decreased tissue weight after feeding the LF diet compared with the HF diets. The concentration of short-chain fatty acids was consistent with the fermentability of carbohydrates in the large intestine, but there was no effect of the dietary composition on the molar short-chain fatty acid proportions. It was further shown that feeding the diet providing the greatest amount of fermentable carbohydrates (diet HF1, which was high in soluble DF) resulted in significant morphological changes in the colon compared with the LF diet.

Kazakhstan In situ BioTransformation of Mercury ...

EPA Pesticide Factsheets

Our final international work on the biological decontamination of the mercury contamination of soils in the Northern outskirts of Pavlodar as a result of activity at the former PO “Khimprom” chemical plant is reported here. The plant produced chlorine and alkali from the 1970s into the 1990s using the electrolytic amalgam method entailing the use of massive amounts of mercury. Ground water became contaminated with Hg resulting in a plume 470 m wide, 1.9 km long, estimated to contain 2 million cubic meters of water. This plume could reach the River Irtysh, a source of drinking water for large cities in Kazakhstan and Russia. Significant amounts of mercuric compounds are deposited in the sediments of Lake Balkyldak, 1.5 km north of the factory. This lake occasionally received wastewater from the factory. Phase I of the PO “Kimprom” clean-up that isolated the major sources of mercury at the site was completed in 2004. However, significant amounts of mercury remain underground including groundwater contaminated with Hg in the form of HgCl2 with little to no elemental or methyl mercury (MeHg).

Leihong, Zhang; Zilan, Pan; Luying, Wu; Xiuhua, Ma

2016-11-01

To solve the problem that large images can hardly be retrieved for stringent hardware restrictions and the security level is low, a method based on compressive ghost imaging (CGI) with Fast Fourier Transform (FFT) is proposed, named FFT-CGI. Initially, the information is encrypted by the sender with FFT, and the FFT-coded image is encrypted by the system of CGI with a secret key. Then the receiver decrypts the image with the aid of compressive sensing (CS) and FFT. Simulation results are given to verify the feasibility, security, and compression of the proposed encryption scheme. The experiment suggests the method can improve the quality of large images compared with conventional ghost imaging and achieve the imaging for large-sized images, further the amount of data transmitted largely reduced because of the combination of compressive sensing and FFT, and improve the security level of ghost images through ciphertext-only attack (COA), chosen-plaintext attack (CPA), and noise attack. This technique can be immediately applied to encryption and data storage with the advantages of high security, fast transmission, and high quality of reconstructed information.

To evaluate the possible protective effect of breast milk against retinopathy of prematurity by comparing the amount of breast milk received by patients who developed retinopathy of prematurity and those who did not and to determine both the required minimum amount of breast milk and the time of life during which neonates need to receive breast milk for this effect to be significant. Cohort study of newborns with a birth weight of <1500 g or gestational age of <32 weeks, or both, born between January 2011 and October 2014 and hospitalized within the first 24 h of life in the Hospital Criança Conceição Neonatal Intensive Care Unit in Porto Alegre, RS, Brazil. The prevalence of retinopathy of prematurity of any degree was 31% (100 of 323 patients) and that of severe retinopathy of prematurity was of 9% (29 of 323 patients). The median amounts of breast milk received daily by patients with and without retinopathy of prematurity were 4.9 mL/kg (interquartile range, 0.3-15.4) and 10.2 mL/kg (1.5-25.5), respectively. The amount of breast milk received in the first 6 weeks of life was inversely associated with the incidence of both retinopathy of prematurity of any degree and severe retinopathy of prematurity in the univariate analyses. However, the statistical significance was maintained only during the sixth week of life in a per-period multivariate analysis controlling for confounding factors. Small amounts of breast milk are inadequate to prevent retinopathy of prematurity in premature newborns at risk for the disease.

To determine the relationship of increasing body mass index (BMI) and abdominal fat on the effective dose acquired from computed tomography (CT) abdomen and pelvis scans. Over 6 months, dose-length product and total milliamp-seconds (mAs) from routine CT abdomen and pelvis scans of 100 patients were recorded. The scans were performed on a 64-slice CT scanner by using an automatic exposure control system. Effective dose (mSv) based on dose-length product, BMI, periumbilical fat thickness, and intra-abdominal fat were documented for each patient. BMI, periumbilical fat thickness, and intra-abdominal fat were compared with effective dose. Thirty-nine men and 61 women were included in the study (mean age, 56.3 years). The mean BMI was 26.2 kg/m(2). The mean effective dose was 10.3 mSv. The mean periumbilical fat thickness was 2.4 cm. Sixty-five patients had a small amount of intra-abdominal fat, and 35 had a large amount of intra-abdominal fat. The effective dose increased with increasing BMI (P < .001) and increasing amounts of intra-abdominal fat (P < .001). For every kilogram of weight, there is a 0.13 mSv increase in effective dose, which is equal to 6.5 chest radiographs per CT examination. For an increase in BMI by 5 kg/m(2), there is a 1.95 mSv increase in effective dose, which is equal to 97.5 chest radiographs per CT examination. Increasing BMI and abdominal fat significantly increases the effective dose received from CT abdomen and pelvis scans. Copyright © 2012 Canadian Association of Radiologists.

Precise Point Positioning (PPP) has become a very hot topic in GNSS research and applications. However, it usually takes about several tens of minutes in order to obtain positions with better than 10 cm accuracy. This prevents PPP from being widely used in real-time kinematic positioning services, therefore, a large effort has been made to tackle the convergence problem. One of the recent approaches is the ionospheric delay constrained precise point positioning (IC-PPP) that uses the spatial and temporal characteristics of ionospheric delays and also delays from an a priori model. In this paper, the impact of the quality of ionospheric models on the convergence of IC-PPP is evaluated using the IGS global ionospheric map (GIM) updated every two hours and a regional satellite-specific correction model. Furthermore, the effect of the receiver differential code bias (DCB) is investigated by comparing the convergence time for IC-PPP with and without estimation of the DCB parameter. From the result of processing a large amount of data, on the one hand, the quality of the a priori ionosphere delays plays a very important role in IC-PPP convergence. Generally, regional dense GNSS networks can provide more precise ionosphere delays than GIM and can consequently reduce the convergence time. On the other hand, ignoring the receiver DCB may considerably extend its convergence, and the larger the DCB, the longer the convergence time. Estimating receiver DCB in IC-PPP is a proper way to overcome this problem. Therefore, current IC-PPP should be enhanced by estimating receiver DCB and employing regional satellite-specific ionospheric correction models in order to speed up its convergence for more practical applications.

2013-07-01

To estimate the proportion of smokers that could potentially have been prevented from smoking by limiting the amount of pocket money received by Chinese adolescents. Cross-sectional study. Current smoking, ever smoking and the amount of pocket money were determined through self-administered questionnaires among 12,708 adolescents (aged 12-18 years) from 21 schools in Shanghai, China. Adjusted odds ratios for current smoking ranged from 2.0 [95% confidence interval (CI) 1.5-2.7] for adolescents receiving 200-399 Reminbin (RMB)/month as pocket money to 6.5 (95% CI 3.3-12.7) for those receiving ≥1000 RMB/month, compared with those receiving <200 RMB/month. The crude population-attributable risk percentage (PAR%) due to higher pocket money (≥200 RMB/month) for current smoking was 50.4% (95% CI 42.2-57.4), and adjusted PAR% was 43.3% (95% CI 30.7-53.1). Approximately half of current smokers may have been prevented from smoking if pocket money was limited to <200 RMB/month among Chinese adolescents. An even larger proportion could have been prevented from smoking if pocket money was reduced further. It is recommended that future intervention programmes should target parents to reduce the amount of pocket money in China. Copyright © 2013 The Royal Society for Public Health.

Metagenomics of rumen bacteriophage from thirteen lactating dairy cattle

PubMed Central

2013-01-01

Background The bovine rumen hosts a diverse and complex community of Eukarya, Bacteria, Archea and viruses (including bacteriophage). The rumen viral population (the rumen virome) has received little attention compared to the rumen microbial population (the rumen microbiome). We used massively parallel sequencing of virus like particles to investigate the diversity of the rumen virome in thirteen lactating Australian Holstein dairy cattle all housed in the same location, 12 of which were sampled on the same day. Results Fourteen putative viral sequence fragments over 30 Kbp in length were assembled and annotated. Many of the putative genes in the assembled contigs showed no homology to previously annotated genes, highlighting the large amount of work still required to fully annotate the functions encoded in viral genomes. The abundance of the contig sequences varied widely between animals, even though the cattle were of the same age, stage of lactation and fed the same diets. Additionally the twelve animals which were co-habited shared a number of their dominant viral contigs. We compared the functional characteristics of our bovine viromes with that of other viromes, as well as rumen microbiomes. At the functional level, we found strong similarities between all of the viral samples, which were highly distinct from the rumen microbiome samples. Conclusions Our findings suggest a large amount of between animal variation in the bovine rumen virome and that co-habiting animals may have more similar viromes than non co-habited animals. We report the deepest sequencing to date of the rumen virome. This work highlights the enormous amount of novelty and variation present in the rumen virome. PMID:24180266

Sediment and water discharge rates of Turkish Black Sea rivers before and after hydropower dam construction

Presently, the water discharge rate to the Black Sea by Turkish rivers is approximately 41 km[sup 3]/yr. The sediment discharge rate of Turkish rivers to the Black Sea is 28 x 10[sup 6] t/yr. Before construction of the hydroelectric dams, the sediment discharge rate was approximately 70 x 10[sup 6] t/yr. The sharp reduction in sediment load is largely a result of the dams near the mouths of the Yesil Irmak and Kizil Irmak rivers. Before the construction of dams, Turkish rivers contributed approximately one third of the total amount of sediment received by the Black Sea from all surroundingmore » rivers. The life-span of the major reservoirs varies from approximately only one century (Yesil Irmak river reservoirs) to several thousand years (Sakarya river reservoirs).

A Scheme for Targeting Optical SETI Observations

NASA Astrophysics Data System (ADS)

Shostak, Seth

2004-06-01

In optical SETI (OSETI) experiments, it is generally assumed that signals will be deliberate, narrowly targeted beacons sent by extraterrestrial societies to large numbers of candidate star systems. If this is so, then it may be unrealistic to expect a high duty cycle for the received signal. Ergo, an advantage accrues to any OSETI scheme that realistically suggests where and when to search. In this paper, we elaborate a proposal (Castellano, Doyle, &McIntosh 2000) for selecting regions of sky for intensive optical SETI monitoring based on characteristics of our solar system that would be visible at great distance. This can enormously lessen the amount of sky that needs to be searched. In addition, this is an attractive approach for the transmitting society because it both increases the chances of reception and provides a large reduction in energy required. With good astrometric information, the transmitter need be no more powerful than an automobile tail light.

Information asymmetry and deception.

Situations such as an entrepreneur overstating a project's value, or a superior choosing to under or overstate the gains from a project to a subordinate are common and may result in acts of deception. In this paper we modify the standard investment game in the economics literature to study the nature of deception. In this game a trustor (investor) can send a given amount of money to a trustee (or investee). The amount received is multiplied by a certain amount, k, and the investee then decides on how to divide the total amount received. In our modified game the information on the multiplier, k, is known only to the investee and she can send a non-binding message to the investor regarding its value. We find that 66% of the investees send false messages with both under and over, statement being observed. Investors are naive and almost half of them believe the message received. We find greater lying when the distribution of the multiplier is unknown by the investors than when they know the distribution. Further, messages make beliefs about the multiplier more pessimistic when the investors know the distribution of the multiplier, while the opposite is true when they do not know the distribution.

Influence of ECG measurement accuracy on ECG diagnostic statements.

PubMed

Zywietz, C; Celikag, D; Joseph, G

1996-01-01

Computer analysis of electrocardiograms (ECGs) provides a large amount of ECG measurement data, which may be used for diagnostic classification and storage in ECG databases. Until now, neither error limits for ECG measurements have been specified nor has their influence on diagnostic statements been systematically investigated. An analytical method is presented to estimate the influence of measurement errors on the accuracy of diagnostic ECG statements. Systematic (offset) errors will usually result in an increase of false positive or false negative statements since they cause a shift of the working point on the receiver operating characteristics curve. Measurement error dispersion broadens the distribution function of discriminative measurement parameters and, therefore, usually increases the overlap between discriminative parameters. This results in a flattening of the receiver operating characteristics curve and an increase of false positive and false negative classifications. The method developed has been applied to ECG conduction defect diagnoses by using the proposed International Electrotechnical Commission's interval measurement tolerance limits. These limits appear too large because more than 30% of false positive atrial conduction defect statements and 10-18% of false intraventricular conduction defect statements could be expected due to tolerated measurement errors. To assure long-term usability of ECG measurement databases, it is recommended that systems provide its error tolerance limits obtained on a defined test set.

Search filters or hedges are search strategies developed to assist information specialists and librarians to retrieve different types of evidence from bibliographic databases. The objectives of this project were to learn about searchers' filter use, how searchers choose search filters and what information they would like to receive to inform their choices. Interviews with information specialists working in, or for, the National Institute for Health and Care Excellence (NICE) were conducted. An online questionnaire survey was also conducted and advertised via a range of email lists. Sixteen interviews were undertaken and 90 completed questionnaires were received. The use of search filters tends to be linked to reducing a large amount of literature, introducing focus and assisting with searches that are based on a single study type. Respondents use numerous ways to identify search filters and can find choosing between different filters problematic because of knowledge gaps and lack of time. Search filters are used mainly for reducing large result sets (introducing focus) and assisting with searches focused on a single study type. Features that would help with choosing filters include making information about filters less technical, offering ratings and providing more detail about filter validation strategies and filter provenance. © 2014 The authors.

Radiation Doses from the Norwegian Diet.

PubMed

Komperød, Mari; Skuterud, Lavrans

2018-06-13

Ingestion doses between and within countries are expected to vary significantly due to differences in dietary habits and geographical variations in radionuclide concentrations. This paper presents the most comprehensive assessment to date of the effective radiation dose from the Norwegian diet, from natural as well as anthropogenic radionuclides. Ingestion doses to the Norwegian public are calculated using national dietary statistics and the most relevant radionuclide concentration data for the various food products. The age-weighted average effective dose received by the Norwegian population from the diet is estimated at 0.41 mSv y from naturally occurring radionuclides and 0.010 mSv y from anthropogenic radionuclides. This is approximately 50% higher than the estimated world average. Fish and shellfish is the food group that provides the largest dose contribution from the average Norwegian diet. Although the average dose from anthropogenic radionuclides today is low, the exposure may still be significant for certain critical groups-especially persons who consume large amounts of reindeer meat from the regions that received significant radioactive fallout after the Chernobyl accident. Furthermore, persons with high Rn concentrations in their drinking water are among those receiving the highest ingestion doses in Norway.

Spatial Patterns of Snow Cover in North Carolina: Surface and Satellite Perspectives

Fuhrmann, Christopher M.; Hall, Dorothy K.; Perry, L. Baker; Riggs, George A.

2010-01-01

Snow mapping is a common practice in regions that receive large amounts of snowfall annually, have seasonally-continuous snow cover, and where snowmelt contributes significantly to the hydrologic cycle. Although higher elevations in the southern Appalachian Mountains average upwards of 100 inches of snow annually, much of the remainder of the Southeast U.S. receives comparatively little snowfall (< 10 inches). Recent snowy winters in the region have provided an opportunity to assess the fine-grained spatial distribution of snow cover and the physical processes that act to limit or improve its detection across the Southeast. In the present work, both in situ and remote sensing data are utilized to assess the spatial distribution of snow cover for a sample of recent snowfall events in North Carolina. Specifically, this work seeks to determine how well ground measurements characterize the fine-grained patterns of snow cover in relation to Moderate- Resolution Imaging Spectroradiometer (MODIS) snow cover products (in this case, the MODIS Fractional Snow Cover product).

PEPFAR Funding Associated With An Increase In Employment Among Males in Ten Sub-Saharan African Countries

Wagner, Zachary; Barofsky, Jeremy; Sood, Neeraj

2016-01-01

The President's Emergency Plan for AIDS Relief (PEPFAR) has provided billions of US tax dollars to expand HIV treatment in sub-Saharan Africa. This investment has generated significant health gains, but much less is known about PEPFAR's population-level economic effects. We use a difference-in-differences approach to compare employment trends between 10 countries that received a large amount of PEPFAR funding against 11 countries that received little or no funding. We find that PEPFAR was associated with a 13% increase in employment among males (95% CI; 3.7%-22.1%), but observe no change in employment among females. In addition, we show that increasing PEPFAR per capita funding by $100 was associated with a 9.1 percentage point increase in employment among males. This rise in employment generates economic benefits equal to half of PEPFAR's cost. These findings suggest that PEPFAR's economic impact must also be taken into account when making aid allocation decisions. PMID:26056199

Childhood Familial Victimization: An Exploration of Gender and Sexual Identity Using the Scale of Negative Family Interactions.

PubMed

Martinez, Katherine; McDonald, Courtney

2017-11-01

Familial violence poses a serious public health concern and has therefore received a considerable amount of attention from academics and practitioners alike. Research within this field has found that parent-to-parent and parent-to-child violence often occur simultaneously and are especially prevalent within households that suffer from social and environmental stressors. Sibling violence and its relationship to these other forms of familial violence has received considerably less attention, largely related to the widely held belief that sibling violence is natural, especially for boys. Using the Scale of Negative Family Interactions (SNFI), parent-to-child and sibling-to-sibling violence is investigated. Specifically, the relationship between participants' gender and sexual identities and their reports of familial violence are explored to better understand participants' gendered and sexed experiences. Data suggest that gender and sexual minorities may have a unique experience of familial violence, although further research is needed in this area.

Design of a Protection Thermal Energy Storage Using Phase Change Material Coupled to a Solar Receiver

NASA Astrophysics Data System (ADS)

Verdier, D.; Falcoz, Q.; Ferrière, A.

2014-12-01

Thermal Energy Storage (TES) is the key for a stable electricity production in future Concentrated Solar Power (CSP) plants. This work presents a study on the thermal protection of the central receiver of CSP plant using a tower which is subject to considerable thermal stresses in case of cloudy events. The very high temperatures, 800 °C at design point, impose the use of special materials which are able to resist at high temperature and high mechanical constraints and high level of concentrated solar flux. In this paper we investigate a TES coupling a metallic matrix drilled with tubes of Phase Change Material (PCM) in order to store a large amount of thermal energy and release it in a short time. A numerical model is developed to optimize the arrangement of tubes into the TES. Then a methodology is given, based from the need in terms of thermal capacity, in order to help the choice of the geometry.

These traverses were made during cleaning operations to assist in the location of any contaminated material in these channels and again after completion of the cleaning operations to determine if all of the contaminated material was removed. Upon completion of the cleaning of the VSR channels and process channels activity traverses were made in all of the channels. The results of these traverses show that no detectable amounts of contaminated materialmore » were present in any of these channels. The traverses made in the VSR channels all show a large peak in the lower part of the pile indicating that the metal in the lower part of the pile received as much as five times the integrated exposure received by the metal in the upper half of the pile. 15 figs.« less

The Pediatric Home Care/Expenditure Classification Model (P/ECM): A Home Care Case-Mix Model for Children Facing Special Health Care Challenges.

Phillips, Charles D

2015-01-01

Case-mix classification and payment systems help assure that persons with similar needs receive similar amounts of care resources, which is a major equity concern for consumers, providers, and programs. Although health service programs for adults regularly use case-mix payment systems, programs providing health services to children and youth rarely use such models. This research utilized Medicaid home care expenditures and assessment data on 2,578 children receiving home care in one large state in the USA. Using classification and regression tree analyses, a case-mix model for long-term pediatric home care was developed. The Pediatric Home Care/Expenditure Classification Model (P/ECM) grouped children and youth in the study sample into 24 groups, explaining 41% of the variance in annual home care expenditures. The P/ECM creates the possibility of a more equitable, and potentially more effective, allocation of home care resources among children and youth facing serious health care challenges.

Digital Transfer Growth of Patterned 2D Metal Chalcogenides by Confined Nanoparticle Evaporation

Developing methods for the facile synthesis of two-dimensional (2D) metal chalcogenides and other layered materials is crucial for emerging applications in functional devices. Controlling the stoichiometry, number of the layers, crystallite size, growth location, and areal uniformity is challenging in conventional vapor phase synthesis. Here, we demonstrate a new route to control these parameters in the growth of metal chalcogenide (GaSe) and dichalcogenide (MoSe 2) 2D crystals by precisely defining the mass and location of the source materials in a confined transfer growth system. A uniform and precise amount of stoichiometric nanoparticles are first synthesized and deposited onto a substratemore » by pulsed laser deposition (PLD) at room temperature. This source substrate is then covered with a receiver substrate to form a confined vapor transport growth (VTG) system. By simply heating the source substrate in an inert background gas, a natural temperature gradient is formed that evaporates the confined nanoparticles to grow large, crystalline 2D nanosheets on the cooler receiver substrate, the temperature of which is controlled by the background gas pressure. Large monolayer crystalline domains (~ 100 m lateral sizes) of GaSe and MoSe 2 are demonstrated, as well as continuous monolayer films through the deposition of additional precursor materials. This novel PLD-VTG synthesis and processing method offers a unique approach for the controlled growth of large-area, metal chalcogenides with a controlled number of layers in patterned growth locations for optoelectronics and energy related applications.« less

Analyzing the security of an existing computer system

Bishop, M.

1986-01-01

Most work concerning secure computer systems has dealt with the design, verification, and implementation of provably secure computer systems, or has explored ways of making existing computer systems more secure. The problem of locating security holes in existing systems has received considerably less attention; methods generally rely on thought experiments as a critical step in the procedure. The difficulty is that such experiments require that a large amount of information be available in a format that makes correlating the details of various programs straightforward. This paper describes a method of providing such a basis for the thought experiment by writing a special manual for parts of the operating system, system programs, and library subroutines.

Empirical relationships between tree fall and landscape-level amounts of logging and fire

Large old trees are critically important keystone structures in forest ecosystems globally. Populations of these trees are also in rapid decline in many forest ecosystems, making it important to quantify the factors that influence their dynamics at different spatial scales. Large old trees often occur in forest landscapes also subject to fire and logging. However, the effects on the risk of collapse of large old trees of the amount of logging and fire in the surrounding landscape are not well understood. Using an 18-year study in the Mountain Ash (Eucalyptus regnans) forests of the Central Highlands of Victoria, we quantify relationships between the probability of collapse of large old hollow-bearing trees at a site and the amount of logging and the amount of fire in the surrounding landscape. We found the probability of collapse increased with an increasing amount of logged forest in the surrounding landscape. It also increased with a greater amount of burned area in the surrounding landscape, particularly for trees in highly advanced stages of decay. The most likely explanation for elevated tree fall with an increasing amount of logged or burned areas in the surrounding landscape is change in wind movement patterns associated with cutblocks or burned areas. Previous studies show that large old hollow-bearing trees are already at high risk of collapse in our study area. New analyses presented here indicate that additional logging operations in the surrounding landscape will further elevate that risk. Current logging prescriptions require the protection of large old hollow-bearing trees on cutblocks. We suggest that efforts to reduce the probability of collapse of large old hollow-bearing trees on unlogged sites will demand careful landscape planning to limit the amount of timber harvesting in the surrounding landscape.

The effect of the 2011 flood on agricultural chemical and sediment movement in the lower Mississippi River Basin

NASA Astrophysics Data System (ADS)

Welch, H.; Coupe, R.; Aulenbach, B.

2012-04-01

Extreme hydrologic events, such as floods, can overwhelm a surface water system's ability to process chemicals and can move large amounts of material downstream to larger surface water bodies. The Mississippi River is the 3rd largest River in the world behind the Amazon in South America and the Congo in Africa. The Mississippi-Atchafalaya River basin grows much of the country's corn, soybean, rice, cotton, pigs, and chickens. This is large-scale modern day agriculture with large inputs of nutrients to increase yields and large applied amounts of crop protection chemicals, such as pesticides. The basin drains approximately 41% of the conterminous United States and is the largest contributor of nutrients to the Gulf of Mexico each spring. The amount of water and nutrients discharged from the Mississippi River has been related to the size of the low dissolved oxygen area that forms off of the coast of Louisiana and Texas each summer. From March through April 2011, the upper Mississippi River basin received more than five times more precipitation than normal, which combined with snow melt from the Missouri River basin, created a historic flood event that lasted from April through July. The U.S. Geological Survey, as part of the National Stream Quality Accounting Network (NASQAN), collected samples from six sites located in the lower Mississippi-Atchafalaya River basin, as well as, samples from the three flow-diversion structures or floodways: the Birds Point-New Madrid in Missouri and the Morganza and Bonnet Carré in Louisiana, from April through July. Samples were analyzed for nutrients, pesticides, suspended sediments, and particle size; results were used to determine the water quality of the river during the 2011 flood. Monthly loads for nitrate, phosphorus, pesticides (atrazine, glyphosate, fluometuron, and metolachlor), and sediment were calculated to quantify the movement of agricultural chemicals and sediment into the Gulf of Mexico. Nutrient loads were compared to historic loads to assess the effect of the flood on the zone of hypoxia that formed in the Gulf of Mexico during the spring of 2011.

A simple biosynthetic pathway for large product generation from small substrate amounts

NASA Astrophysics Data System (ADS)

Djordjevic, Marko; Djordjevic, Magdalena

2012-10-01

A recently emerging discipline of synthetic biology has the aim of constructing new biosynthetic pathways with useful biological functions. A major application of these pathways is generating a large amount of the desired product. However, toxicity due to the possible presence of toxic precursors is one of the main problems for such production. We consider here the problem of generating a large amount of product from a potentially toxic substrate. To address this, we propose a simple biosynthetic pathway, which can be induced in order to produce a large number of the product molecules, by keeping the substrate amount at low levels. Surprisingly, we show that the large product generation crucially depends on fast non-specific degradation of the substrate molecules. We derive an optimal induction strategy, which allows as much as three orders of magnitude increase in the product amount through biologically realistic parameter values. We point to a recently discovered bacterial immune system (CRISPR/Cas in E. coli) as a putative example of the pathway analysed here. We also argue that the scheme proposed here can be used not only as a stand-alone pathway, but also as a strategy to produce a large amount of the desired molecules with small perturbations of endogenous biosynthetic pathways.

The ultimate ambient-intelligent care room contains numerous sensors and devices to monitor the patient, sense and adjust the environment and support the staff. This sensor-based approach results in a large amount of data, which can be processed by current and future applications, e.g., task management and alerting systems. Today, nurses are responsible for coordinating all these applications and supplied information, which reduces the added value and slows down the adoption rate.The aim of the presented research is the design of a pervasive and scalable framework that is able to optimize continuous care processes by intelligently reasoning on the large amount of heterogeneous care data. The developed Ontology-based Care Platform (OCarePlatform) consists of modular components that perform a specific reasoning task. Consequently, they can easily be replicated and distributed. Complex reasoning is achieved by combining the results of different components. To ensure that the components only receive information, which is of interest to them at that time, they are able to dynamically generate and register filter rules with a Semantic Communication Bus (SCB). This SCB semantically filters all the heterogeneous care data according to the registered rules by using a continuous care ontology. The SCB can be distributed and a cache can be employed to ensure scalability. A prototype implementation is presented consisting of a new-generation nurse call system supported by a localization and a home automation component. The amount of data that is filtered and the performance of the SCB are evaluated by testing the prototype in a living lab. The delay introduced by processing the filter rules is negligible when 10 or fewer rules are registered. The OCarePlatform allows disseminating relevant care data for the different applications and additionally supports composing complex applications from a set of smaller independent components. This way, the platform significantly reduces the amount of information that needs to be processed by the nurses. The delay resulting from processing the filter rules is linear in the amount of rules. Distributed deployment of the SCB and using a cache allows further improvement of these performance results.

Organic matter in a subtropical mangrove-estuary subjected to wastewater discharge: Origin and utilisation by two macrozoobenthic species

NASA Astrophysics Data System (ADS)

Meziane, Tarik; Tsuchiya, Makoto

2002-02-01

Total lipid amounts, fatty acid signature analysis, and C:N measurements were used to investigate the sources of organic matter in an Okinawan estuary (Okukubi, Japan) during the 1999 rainy season. This estuary has a mangrove forest and receives agricultural wastewater. Highest concentrations of total lipids and lowest C:N values were simultaneously found near the pipe where the agricultural water is discharged. Fatty acid profiles in the sediments varied among the stations, indicating differences in the contributing organic sources. Small amounts of lipids and low relative contributions of long-chain fatty acids, markers of vascular plants, were found at stations within and adjacent to the mangrove. These results indicate that the export of organic matter from the mangrove litter to the intertidal flat was limited and spatially restricted. The wastewater seems to induce high amounts of bacteria, macroalgae and benthic diatoms, as indicated by their respective fatty acid markers. The fatty acid profiles of the tissues of two dominant intertidal invertebrates, the crab Uca vocans and the gastropod Terebralia sulcata, indicated that their diet was largely comprised of bacteria. Green macroalgae were important food sources for the gastropods; diatoms and mangrove biomass contributed to the nutrition of the crabs, although their contributions were smaller.

Solar power satellite life-cycle energy recovery consideration

NASA Astrophysics Data System (ADS)

Weingartner, S.; Blumenberg, J.

The construction, in-orbit installation and maintenance of a solar power satellite (SPS) will demand large amounts of energy. As a minimum requirement for an energy effective power satellite it is asked that this amount of energy be recovered. The energy effectiveness in this sense resulting in a positive net energy balance is a prerequisite for cost-effective power satellite. This paper concentrates on life-cycle energy recovery instead on monetary aspects. The trade-offs between various power generation systems (different types of solar cells, solar dynamic), various construction and installation strategies (using terrestrial or extra-terrestrial resources) and the expected/required lifetime of the SPS are reviewed. The presented work is based on a 2-year study performed at the Technical University of Munich. The study showed that the main energy which is needed to make a solar power satellite a reality is required for the production of the solar power components (up to 65%), especially for the solar cell production. Whereas transport into orbit accounts in the order of 20% and the receiving station on earth (rectenna) requires about 15% of the total energy investment. The energetic amortization time, i.e. the time the SPS has to be operational to give back the amount of energy which was needed for its production installation and operation, is about two years.

Aim of this study is to compare the clinical and radiographic success of non-surgical endodontic therapy in patients receiving intravenous zolendronate less than 1 year and more than 1 year. The clinical and radiographic follow-up data of 24 patients who were receiving IV zolendronate with 37 teeth were retrieved from the archives to evaluate clinical and radiographic healing at the end of 12 months after non-surgical endodontic therapy. The clinical and radiographic scores of teeth treated with non-surgical endodontic therapy were analyzed. The amount of non-healed and incomplete healed teeth in patients receiving zolendronate more than 1 year were more than the amount of teeth of non-healed and incomplete healed in patients receiving bisphosphonates less than 1 year (p <0.05). There was a strong relationship between the duration of the bisphosphonate medication and endodontic success.

Control design challenges of large space systems and spacecraft control laboratory experiment (SCOLE)

NASA Technical Reports Server (NTRS)

Lin, Jiguan Gene

1987-01-01

The quick suppression of the structural vibrations excited by bang-bang (BB) type time-optional slew maneuvers via modal-dashpot design of velocity output feedback control was investigated. Simulation studies were conducted, and modal dashpots were designed for the SCOLE flexible body dynamics. A two-stage approach was proposed for rapid slewing and precision pointing/retargeting of large, flexible space systems: (1) slew the whole system like a rigid body in a minimum time under specified limits on the control moments and forces, and (2) damp out the excited structural vibrations afterwards. This approach was found promising. High-power modal/dashpots can suppress very large vibrations, and can add a desirable amount of active damping to modeled modes. Unmodeled modes can also receive some concomitant active damping, as a benefit of spillover. Results also show that not all BB type rapid pointing maneuvers will excite large structural vibrations. When properly selected small forces (e.g., vernier thrusters) are used to complete the specified slew maneuver in the shortest time, even BB-type maneuvers will excite only small vibrations (e.g., 0.3 ft peak deflection for a 130 ft beam).

In this proof-of-concept trial, we examined the feasibility and preliminary efficacy of Understanding Social Situations (USS), a new social-cognitive intervention that targets higher level social-cognitive skills using methods common to neurocognitive remediation, including drill and practice and hierarchically structured training, which may compensate for the negative effects of cognitive impairment on learning. Thirty-eight individuals with schizophrenia spectrum disorders completed the same baseline assessment of cognitive and social-cognitive functioning twice over a 1-month period to minimize later practice effects, then received 7-10 sessions of USS training, and then completed the same assessment again at posttreatment. USS training was well tolerated and received high treatment satisfaction ratings. Large improvements on the USS Skills Test, which contained items similar to but not identical to training stimuli, suggest that we were effective in teaching specific training content. Content gains generalized to improvements on some of the social-cognitive tasks, including select measures of attributional bias and theory of mind. Importantly, baseline neurocognition did not impact the amount of learning during USS (as indexed by the USS Skills Test) or the amount of improvement on social-cognitive measures. USS shows promise as a treatment for higher level social-cognitive skills. Given the lack of relationship between baseline cognition and treatment effects, it may be particularly appropriate for individuals with lower range cognitive function.

Effects of Land Use and Lithology on the Origin and Cycling of Dissolved Inorganic Carbon in the Brazos River, Texas

NASA Astrophysics Data System (ADS)

Zeng, F.; Masiello, C. A.

2009-12-01

Global rivers annually receive significant amounts of both inorganic and organic carbon from land. The fate of this terrestrial carbon depends largely on factors such as climate, lithology, land use and topography. In this study, we focused on dissolved inorganic carbon (DIC). We directly measured the partial pressure of CO2 (pCO2), and stable and radiocarbon isotopes of riverine DIC to understand how land use and lithology control the origin and cycling of DIC in the Brazos River. We observed a significant difference in the sources and fate of DIC between the middle and lower Brazos. In the middle Brazos, a combination of damming and waste water discharge from urban areas appears to have promoted algal growth, resulting in low pCO2 (646 ± 216 μatm) and young DIC (Δ14C = +85 ± 63‰) in the river water. In the lower Brazos, higher pCO2 (1174 ± 418 μatm) and much older riverine DIC (Δ14C = -151 ± 52‰) are due to a combination of the presence of easily erodible carbonate bedrock (marl) and oyster shells used as construction aggregates, and old organic matter lost from soils caused by agricultural activities. Overall, of the terrestrial inorganic carbon the Brazos received, a larger amount is delivered to the ocean while a smaller fraction is returned to the atmosphere through CO2 outgassing, which is different from the observation in the Amazon River.

Radiation doses to local populations near nuclear weapons test sites worldwide.

Simon, Steven L; Bouville, André

2002-05-01

Nuclear weapons testing was conducted in the atmosphere at numerous sites worldwide between 1946 and 1980, which resulted in exposures to local populations as a consequence of fallout of radioactive debris. The nuclear tests were conducted by five nations (United States, Soviet Union, United Kingdom, France, and China) primarily at 16 sites. The 16 testing sites, located in nine different countries on five continents (plus Oceania) contributed nearly all of the radioactive materials released to the environment by atmospheric testing; only small amounts were released at a fewother minor testing sites. The 16 sites discussed here are Nevada Test Site, USA (North American continent), Bikini and Enewetak, Marshall Islands (Oceania); Johnston Island, USA (Oceania), Christmas and Malden Island, Kiribati (Oceania); Emu Field, Maralinga, and Monte Bello Islands, Australia (Australian continent); Mururoa and Fangataufa, French Polynesia (Oceania), Reggane, Algeria (Africa), Novaya Zemlya and Kapustin Yar, Russia (Europe), Semipalatinsk, Kazakhstan (Asia), and Lop Nor, China (Asia). There were large differences in the numbers of tests conducted at each location and in the total explosive yields. Those factors, as well as differences in population density, lifestyle, environment, and climate at each site, led to large differences in the doses received by local populations. In general, the tests conducted earliest led to the highest individual and population exposures, although the amount of information available for a few of these sites is insufficient to provide any detailed evaluation of radiation exposures. The most comprehensive information for any site is for the Nevada Test Site. The disparities in available information add difficulty to determining the radiation exposures of local populations at each site. It is the goal of this paper to summarize the available information on external and internal doses received by the public living in the regions near each of the mentioned nuclear test sites as a consequence of local fallout deposition.

How Does Cash and Counseling Affect Costs?

2007-01-01

Objective To test the effect of a consumer-directed model (Cash and Counseling) of Medicaid personal care services (PCS) or home-and community-based waiver services (HCBS) on the cost of Medicaid services. Data Sources/Study Setting Medicaid claims data were collected for all enrollees in the Cash and Counseling demonstration. Demonstration enrollees included those eligible for PCS (in Arkansas), those assessed to receive such services (in New Jersey), and recipients of Medicaid HCBS (in Florida). Enrollment occurred from December 1998 through April 2001. The follow-up period covered up to 24 months after enrollment. Study Design Demonstration volunteers were randomly assigned to have the option to participate in Cash and Counseling (the treatment group), or to receive Medicaid services as usual from an agency (the control group). Ordinary least squares regressions were used to estimate the effect of the program on costs for Medicaid PCS/waiver services and other Medicaid services, while controlling for consumers' preenrollment characteristics and preenrollment Medicaid spending. Models were estimated separately for nonelderly and elderly adults in each state and for children in Florida. Data Extraction Methods Each state supplied claims data for demonstration enrollees. Principal Findings Largely because the program increased consumers' ability to get the authorized amount of paid care, expenditures for personal care/waiver services were higher for the treatment group than for the control group in each state and age group, except among the elderly in Florida. Higher costs for personal care/waiver services were partially offset by savings in other Medicaid services, particularly those related to long-term care. During year 1, total Medicaid costs were generally higher for the treatment group than for the control group, with treatment–control cost differences ranging from 1 percent (and statistically insignificant) for the elderly in Florida to 17 percent for the elderly in Arkansas. In year 2, these cost differences were generally greater than in year 1. Only in Arkansas did the treatment–control difference in total cost shrink over time—to less than 5 percent (and statistically insignificant) in year 2. Conclusions Medicaid costs were generally higher under Cash and Counseling because those in the traditional system did not get the services they were entitled to. Compared with the treatment group, (1) control group members were less likely to receive any services at all (despite being authorized for them), and (2) service recipients received a lower proportion of the amount of care that was authorized. In addition, a flaw in Florida's reassessment procedures led to treatment group members receiving more generous benefit amounts than control group members. To keep total Medicaid costs per recipient at the level incurred under the traditional system, consumer-directed programs need to be carefully designed and closely monitored. PMID:17244294

Previous studies have addressed post-operative pain management after ACL reconstruction by examining the use of intra-articular analgesia and/or modification of anesthesia techniques. To our knowledge, however, no previous studies have evaluated the effect of zolpidem on post-operative narcotic requirements, pain, and fatigue in patients undergoing outpatient arthroscopic ACL reconstruction. The purpose of this prospective, blinded, randomized, controlled clinical study was to evaluate the effect of zolpidem on post-operative narcotic requirements, pain, and fatigue in patients undergoing outpatient arthroscopic ACL reconstruction. Twenty-nine patients undergoing arthroscopic ACL reconstruction were randomized to a treatment group or placebo group. Both groups received post-operative hydrocodone/acetaminophen bitartrate (Vicodin ES). Patients in the treatment group received a single dose of zolpidem for the first seven post-operative nights. Patients in the placebo group received a gelatin capsule similar in appearance to zolpidem. The amount of Vicodin used in each group, the amount of post-operative pain, and the amount of post-operative fatigue were analyzed. Following ACL reconstruction, a 28% reduction was seen in the total amount of narcotic consumed with zolpidem (P = 0.047) when compared to placebo. There were no significant differences in post-operative pain or fatigue levels between zolpidem and placebo. Adding zolpidem to the post-operative medication regimen after arthroscopic ACL reconstruction helps to lower the amount of narcotic pain medication required for adequate analgesia.

1999-12-01

To undertake a survey of the advertising of new drugs in the general practice literature as part of a larger study investigating the factors which influence the introduction of new drugs into clinical practice. The advertisements for nine new drugs from a range of therapeutic groups were monitored for 30 months in 12 journals, which are received by most GPs. The amount of prescribing, in defined daily doses, of each new drug by 50 GPs, selected as regular users of a teaching hospital, was also recorded during this period. Of the journals, 798 issues were surveyed (93% of the total published). The total number of advertisements was almost 33 000, of which 2163 (6.6%) were for the study drugs. The pattern of advertising of each study drug was very complex and varied from month to month and between journals. There was no consistent pattern in the way the drugs were advertised, with large variations in the amount and timing of advertisements. The prescribing data showed wide variations in the number of GPs prescribing each drug and in the amount prescribed. There was no clear relationship between the extent of the advertising of a drug and the amount of prescribing by the GPs. This suggests that advertising in journals is only one of many factors which are important in influencing GPs to prescribe new drugs. However, the study may have been insufficiently comprehensive to capture complex relationships between advertising and prescribing.

Renewing membership in three community-based health insurance schemes in rural India.

PubMed

Panda, Pradeep; Chakraborty, Arpita; Raza, Wameq; Bedi, Arjun S

2016-12-01

Low renewal rate is a key challenge facing the sustainability of community-based health insurance (CBHI) schemes. While there is a large literature on initial enrolment into such schemes, there is limited evidence on the factors that impede renewal. This article uses longitudinal data to analyse what determines renewal, both 1 year and 2 years after the introduction of three CBHI schemes, which have been operating in rural Bihar and Uttar Pradesh since 2011. We find that initial scheme uptake is ∼23-24% and that 2 years after scheme operation, only ∼20% of the initial enrolees maintain their membership. A household's socio-economic status does not seem to play a large role in impeding renewal. In some instances, a greater understanding of the scheme boosts renewal. The link between health status and use of health care in maintaining renewal is mixed. The clearest effect is that individuals living in households that have received benefits from the scheme are substantially more likely to renew their contracts. We conclude that the low retention rates may be attributed to limited benefit packages, slow claims processing times and the gap between the amounts claimed and amounts paid out by insurance. © The Author 2016.

Coaching positively influences the effects of working memory training on visual working memory as well as mathematical ability.

PubMed

Nelwan, Michel; Vissers, Constance; Kroesbergen, Evelyn H

2018-05-01

The goal of the present study was to test whether the amount of coaching influenced the results of working memory training on both visual and verbal working memory. Additionally, the effects of the working memory training on the amount of progress after specific training in mathematics were evaluated. In this study, 23 children between 9 and 12 years of age with both attentional and mathematical difficulties participated in a working memory training program with a high amount of coaching, while another 25 children received no working memory training. Results of these groups were compared to 21 children who completed the training with a lower amount of coaching. The quality of working memory, as well as mathematic skills, were measured three times using untrained transfer tasks. Bayesian statistics were used to test informative hypotheses. After receiving working memory training, the highly coached group performed better than the group that received less coaching on visual working memory and mathematics, but not on verbal working memory. The highly coached group retained their advantage in mathematics, even though the effect on visual working memory decreased. However, no added effect of working memory training was found on the learning curve during mathematical training. Moreover, the less-coached group was outperformed by the group that did not receive working memory training, both in visual working memory and mathematics. These results suggest that motivation and proper coaching might be crucial for ensuring compliance and effects of working memory training, and that far transfer might be possible.

A total of 7006 first admissions in 1994-6 (pre-PPS) and 61,569 first admissions in 2000-1 (post-PPS). A logistic model predicting likelihood of rehabilitation was developed and validated in pre-PPS admissions and applied to the post-PPS patients. Rehabilitation services were compared in the pre-PPS and post-PPS cohorts overall, stratified by quintile of predicted score, diagnosis group, and by nursing home profit status. Post-PPS patients had less cognitive impairment, more depression, and more family support. The amount of rehabilitation services declined the most in the higher quintiles of predicted likelihood of rehabilitation and among patients with stroke. The percent of patients receiving rehabilitation services increased the most in the lowest quintile and among patients with medical conditions. These changes were greater in for-profit nursing homes. The implementation of the PPS in nursing homes has been associated with a decrease in the amount of rehabilitation services, targeted at those predicted to receive higher amounts and an increased frequency of providing services targeted at those predicted to be less likely to receive them. The outcomes of the changes deserve further study.

Bourque, Alda L; Sullivan, Mary E; Winter, Michael R

The purpose of this study was to determine whether the use of Reiki decreases the amount of meperidine administered to patients undergoing screening colonoscopy. The literature review reveals limited studies to show whether Reiki has been able to decrease the amount of opioid the patient receives during screening colonoscopy. A chart review of 300 patients was conducted to obtain baseline average doses of meperidine patients received as the control. Following the chart review, 30 patients were recruited to the Reiki study. Twenty-five of the study arm patients received Reiki in conjunction with meperidine. Five randomly chosen study arm patients received placebo Reiki in conjunction with meperidine in an attempt to blind the clinicians to the treatment received by the patients. Results showed that there were no significant differences in meperidine administration between the patients in the chart review group (control) and the Reiki group. The study revealed that 16% who received Reiki, together with intravenous administration of conscious sedation, received less than 50 mg of meperidine. All the patients in the chart review group received more than 50 mg of meperidine. Results from this pilot study suggest that there may be a decrease in meperidine needed during screening colonoscopy when patients receive Reiki treatments before the procedure. A larger study powered to detect smaller medication differences is the next step in more accurately determining the effect of Reiki on pain management.

EFFECTS OF PROTEINURIA ON THE KIDNEY

Baxter, James H.; Cotzias, George C.

1949-01-01

Repeated intraperitoneal injections twice daily of various proteins into young rats were regularly accompanied by an increase in the protein content of the urine, significant renal enlargement, and often some degree of renal pallor. The most marked changes were induced by gelatin, followed in order by human albumin and bovine globulin. Rat serum produced similar but less conclusive changes. Similar changes were not produced by equivalent amounts of urea or casein hydrolysate. In sections from the kidneys of animals receiving gelatin, the cells of the convoluted tubules appeared enlarged, and they contained clear "spaces" throughout the cytoplasm. The tubular cells of the animals receiving the other solutions were not obviously altered in size or shape, and the cytoplasmic changes were slight or absent. There was little evidence of increased multiplication of cells or of tubular dilatation in the kidneys of any of the groups. Changes in concentrations of plasma proteins and hemoglobin, and the results of preliminary studies of the injected proteins in urine and renal tissue following the injections, are described and their possible significance discussed. It appears that the renal enlargement, as well as the increase in proteinuria and the tubular alterations which followed the protein injections, might have been caused in part by effects on the kidney of protein molecules per se, perhaps most likely by the effects on the tubular cells of an increased amount of protein filtered through the glomerular membranes, rather than entirely by effects of products of protein digestion and metabolism reaching the kidney through the blood stream. In the majority of animals there was no evidence from the morphological or functional studies, that the prolonged and continuous proteinuria induced by the protein injections resulted in renal damage, unless the renal enlargement, and the cytoplasmic changes which occurred regularly with gelatin, are considered evidence of damage. Renal enlargement and proteinuria promptly regressed after injections were discontinued. Lesions characterized by severe degrees of tubular damage, possibly as a result of tubular plugging, were observed in some of the animals of one group receiving gelatin solution of the usual concentration, and dilatation of renal tubules and glomerular capsules was present in some other gelatin-treated animals autopsied after relatively brief injection periods. A description is also presented of lesions of remarkable character which developed in the kidneys of all the animals of one small group receiving homologous serum obtained from severely anoxic donors. The possible relationship between the renal changes in the protein-injected animals and certain alterations of the kidneys observed in diseases characterized by large amounts of protein in the urine, is considered.

The coagulopathy of acute liver failure and implications for intracranial pressure monitoring.

PubMed

Munoz, Santiago J; Rajender Reddy, K; Lee, William

2008-01-01

The development of coagulopathy in acute liver failure (ALF) is universal. The severity of the coagulopathy is often assessed by determination of the prothrombin time and International Normalized Ratio (INR). In more than 1,000 ALF cases, the severity of the coagulopathy was moderate in 81% (INR 1.5-5.0), severe in 14% (INR 5.0-10.0), and very severe in 5% (INR > 10.0). Certain etiologies were associated with more severe coagulopathy, whereas ALF caused by fatty liver of pregnancy had the least severe coagulopathy. Management consisted of transfusions of FFP in 92%. Overall, FFP administered during the first week of admission amounted to 13.7 +/- 15 units. Patients who received an ICP monitor had significantly more FFP transfused than those managed without ICP monitor (22.7 +/- 2.4 vs. 12.3 +/- 0.8 units FFP; P < 0.001). Only a minority of patients developed gastrointestinal bleeding or had an intracranial pressure monitor installed. Further research is necessary to explore the reasons clinicians transfuse ALF patients with large amounts of FFP in the absence of active bleeding or invasive procedures.

Food stamps and meal vouchers can determine workers' dietary choices. The study aimed to assess the coverage of these benefits in Brazil and their distribution according to the beneficiaries' socio-demographic and regional characteristics, using data from the Brazilian Household Budgets Survey, 2008-2009. Eligibility criteria were having an occupation and a private or government job, including domestic or temporary work in rural areas. Only 3.2% of eligible individuals reported receiving such benefits. Highest coverage rates were verified with the Southeast region, urban areas, male gender, employment in the private sector, and monthly earnings > five times the minimum wage. The mean monthly amount of such benefits was R$ 177.20 (US$ 100 at the 2009 exchange rate). After adjusting for other variables, the highest amounts were associated with male gender, higher salaries, the Northeast and Central regions, and employment in the public sector. This first analysis of the national coverage of food stamps and meal vouchers showed that a large share of Brazilian workers lack access or have unequal access to such benefits.

Nanoparticle-Based Manipulation of Antigen-Presenting Cells for Cancer Immunotherapy.

PubMed

Fang, Ronnie H; Kroll, Ashley V; Zhang, Liangfang

2015-11-04

Immunotherapeutic approaches for treating cancer overall have been receiving a considerable amount of interest due to the recent approval of several clinical formulations. Among the different modalities, anticancer vaccination acts by training the body to endogenously generate a response against tumor cells. However, despite the large amount of work that has gone into the development of such vaccines, the near absence of clinically approved formulations highlights the many challenges facing those working in the field. The generation of potent endogenous anticancer responses poses unique challenges due to the similarity between cancer cells and normal, healthy cells. As researchers continue to tackle the limited efficacy of vaccine formulations, fresh and novel approaches are being sought after to address many of the underlying problems. Here the application of nanoparticle technology towards the development of anticancer vaccines is discussed. Specifically, there is a focus on the benefits of using such strategies to manipulate antigen presenting cells (APCs), which are essential to the vaccination process, and how nanoparticle-based platforms can be rationally engineered to elicit appropriate downstream immune responses. © 2015 WILEY-VCH Verlag GmbH & Co.

2004-01-01

The direct impact of the Mississippi River on the open Gulf of Mexico is typically considered to be limited due to the predominantly along-shore current pattern. Using satellite imagery, we analyzed chl a distributions in the northern Gulf of Mexico before and after the passage of two storms: Hurricane Lili and Tropical Storm Barry. Our analyses indicate that storm-induced eddies can rapidly inject large volumes of nutrient-rich Mississippi River water to the open gulf, and lead to phytoplankton blooms. Although these events last only a few weeks, they transport significant amounts of fluvial substances to the ocean. These river-ocean interactions are especially significant in tropical and subtropical regions because receiving waters are typically permanently stratified and oligotrophic.

Experimental and theoretical studies on solar energy for energy conversion

This paper presents the results of investigations made experimentally and theoretically to evaluate the various parameters that affect the amount of solar energy received on a collector surface. Measurements were made over a long period of time using both pyranometer and pyrheliometer. Computation of spectral and total irradiance at ground level have been made for a large variety of combinations of atmospheric parameters for ozone density, precipitable water vapor, turbidity-coefficients and air mass. A study of the air mass as a function of irradiance measured at GSFC, and comparison of the data with the computed values of total direct solar irradiance for various parameters indicate that turbidity changes with time of the day; atmospheric opacity is less in the afternoon than in the morning.

Microstructure and mechanical properties of bulk and plasma-sprayed y2O3-partially stabilized zirconia

NASA Technical Reports Server (NTRS)

Valentine, P. G.; Maier, R. D.

1980-01-01

Bulk 8.0 weight percent yttria partially stabilied zirconia (PSZ) was studied by light microscopy, transmission electron microscopy, X-ray analysis, microhardness testing, and fracture toughness testing. The as received PSZ contained spheroidal and grain boundary precipitates up to 4 micrometers in size. Spheroids up to 1.26 micrometers were metastable tetragonal; large spheroids were monoclinic. Grinding the PSZ into powder did not cause a significant amount of tetragonal to transform to monoclinic. This indicates that transformation toughness is not a significant mechanism in PSZ. Aging the PSZ at 1500 C caused the fine tetragonal precipitates to grow from 0.06 to 0.12 micrometers, in 250 minutes. A peak hardness of 1400 kg/sq mm was attained after 50 minutes. Solution annealing and quenching the as received PSZ eliminated the large precipitates, but fine tetragonal precipitates reformed on quenching. Aging at 1500 C caused the fine 0.02 micrometers tetragonal precipitates to grow into plates about 0.10 by 0.50 micrometers. A peak hardness of 1517 kg/sq mm was obtained after 250 minutes. On further aging, monoclinic percipitates formed along grain boundaries. The fracture toughness of the aged and unaged solution annealed and quenched PSZ was found to be between 2 and 3 MN /square root of m cubed. This range of fracture toughness is consistent with PSZ's that do not undergo transformation toughening.

Red blood cell (RBC) transfusions are associated with increased morbidity. Children receiving heart transplants constitute a unique group of patients due to their risk factors. Although previous studies in nontransplant patients have focused primarily on the effects of postoperative blood transfusions, a significant exposure to blood occurs during the intraoperative period, and a larger percentage of heart transplant patients require intraoperative blood transfusions when compared with general cardiac surgery patients. We investigated the relationship between clinical outcomes and the amount of blood transfused both during and after heart transplantation. We hypothesized that larger amounts of RBC transfusions are associated with worsening clinical outcomes in pediatric heart transplant patients. A database comprising 108 pediatric patients undergoing heart transplantation from 2004 to 2010 was queried. Preoperative and postoperative clinical risk factors, including the amount of blood transfused intraoperatively and 48 hours postoperatively, were analyzed. The outcome measures were length of hospital stay, duration of tracheal intubation, inotrope score, and major adverse events. Bivariate and multivariate analyses were performed to control for simultaneous risk factors and determine outcomes in which the amount of blood transfused was an independent risk factor. Ninety-four patients with complete datasets were included in the final analysis. Eighty-eight percent received RBC transfusions, with a median transfusion amount of 38.7 mL/kg. A multivariate analysis correcting for 8 covariate risk factors, including the Index for Mortality Prediction After Cardiac Transplantation, age, weight, United Network for Organ Sharing status, warm and cold ischemia time, repeat sternotomy, and pretransplant hematocrit, showed RBC transfusions were independently associated with increased length of intensive care unit stay (means ratio = 1.34; 95% confidence interval, 1.03-1.76; P = 0.03), and increased inotrope score in the first postoperative 24 hour (mean ratio = 1.26; 95% confidence interval, 1.04-1.52; P = 0.04). Patients suffering major adverse events received significantly larger median amounts of blood RBC transfusions (P = 0.002). Transfusions >60 mL/kg were also associated with increased risk of major adverse events (accuracy 76%) including postoperative sepsis, extracorporeal membrane oxygenation, open chest, dialysis, and graft failure. The majority of pediatric patients undergoing orthotropic heart transplantation receive RBC transfusions, with the largest amount transfused in the operating room. Escalating amounts of RBC transfusions are independently associated with increased length of intensive care unit stay, inotrope scores, and major adverse events. Since heart allografts are a limited resource, improvement in the blood transfusion and conservation practices can enhance clinical outcomes in pediatric heart transplant patients.

Screening procedure to assess the impact of urban stormwater temperature to populations of brown trout in receiving water.

PubMed

Rossi, Luca; Hari, Renata E

2007-07-01

The discharge of urban stormwater may cause a sudden temperature increase in receiving waters that may be harmful to fish and other aquatic organisms. A screening procedure is proposed with temperature thresholds for the runoff from roofs and roads as well as for the receiving water system to protect brown trout from thermal damage. The stormwater temperature is calculated on the basis of a simple thermodynamic estimate for different latitudes. Only receiving waters with maximum daily mean temperatures of 22 degrees C (T1) are considered potential habitats for brown trout. The maximum temperature for a 1-h exposure time with a safety margin for 100% survival is 25 degrees C (T2), the sudden temperature change at the beginning of a rain event must not exceed 7 degrees C (T3), and fish-egg development requires the daily maximum temperature in winter to be below 12 degrees C (T4). Examples of stormwater runoff from roof or road surfaces from Switzerland validate our approach within +/-0.5 degrees C. Effects of runoff into receiving waters without detailed data can be predicted within +/-0.8 degrees C. With the restriction by T1, T2 seems not to be an acute problem at Swiss latitudes. T3 could play a role, especially if a large amount of runoff is discharged in small and rather cool rivers and streams. Finally, T4 deserves more attention than hitherto given. The proposed procedure may be a useful tool for assessing the influence of urban stormwater on the temperature of the receiving waters, particularly with regard to predicting the thermal impacts of urban or suburban runoff to populations of brown trout.

Understanding the information needs of people with haematological cancers. A meta-ethnography of quantitative and qualitative research.

PubMed

Atherton, K; Young, B; Salmon, P

2017-11-01

Clinical practice in haematological oncology often involves difficult diagnostic and treatment decisions. In this context, understanding patients' information needs and the functions that information serves for them is particularly important. We systematically reviewed qualitative and quantitative evidence on haematological oncology patients' information needs to inform how these needs can best be addressed in clinical practice. PsycINFO, Medline and CINAHL Plus electronic databases were searched for relevant empirical papers published from January 2003 to July 2016. Synthesis of the findings drew on meta-ethnography and meta-study. Most quantitative studies used a survey design and indicated that patients are largely content with the information they receive from physicians, however much or little they actually receive, although a minority of patients are not content with information. Qualitative studies suggest that a sense of being in a caring relationship with a physician allows patients to feel content with the information they have been given, whereas patients who lack such a relationship want more information. The qualitative evidence can help explain the lack of association between the amount of information received and contentment with it in the quantitative research. Trusting relationships are integral to helping patients feel that their information needs have been met. © 2017 John Wiley & Sons Ltd.

Under the proposed plan, DOE would allocate ration rights (rights to purchase gasoline) to owners of registered vehicles. All vehicles in a given class would receive the same entitlement. Essential services would receive supplemental allotments of ration rights as pririty firms. Once every 3 months, ration checks would be mailed out to all vehicle registrants, allotting them a certain amount of ration rights. These checks would then be cashed at Coupon Issuance Points, where the bearer would receive ration coupons to be used at gasoline stations. Large users of gasoline could deposit their allotment checks in accounts at ration banks.more » Coupons or checks would be freely exchangeable in a white market. A certain percentage of the gasoline supply would be set aside in reserve for use in national emergencies. When the plan was published in the Federal Register, public comments were requested. DOE also solicited comments from private citizens, public interest groups, business and industry, state and local governments. A total of 1126 responses were reveived and these are analyzed in this paper. The second part of the report describes how the comments were classified, and gives a statistical breakdown of the major responses. The last section is a discussion and analysis of theissue raised by commenting agencies, firms, associations, and individuals. (MCW)« less

A Tier-2 regional center is running at the University of Tokyo in Japan. This center receives a large amount of data of the ATLAS experiment from the Tier-1 center in France. Although the link between the two centers has 10Gbps bandwidth, it is not a dedicated link but is shared with other traffic, and the round trip time is 290ms. It is not easy to exploit the available bandwidth for such a link, so-called long fat network. We performed data transfer tests by using GridFTP in various combinations of the parameters, such as the number of parallel streams and the TCP window size. In addition, we have gained experience of the actual data transfer in our production system where the Disk Pool Manager (DPM) is used as the Storage Element and the data transfer is controlled by the File Transfer Service (FTS). We report results of the tests and the daily activity, and discuss the improvement of the data transfer throughput.

Recent findings demonstrate that the most effective reading instruction may vary with children’s language and literacy skills. These child X instruction interactions imply that individualizing instruction would be a potent strategy for improving students’ literacy. A cluster-randomized control field trial, conducted in 10 high-moderate poverty schools, examined effects of individualizing literacy instruction. The instruction each first grader received (n=461 in 47 classrooms, mean age = 6.7 years), fall, winter and spring, was recorded. Comparing intervention-recommended amounts of instruction with observed amounts revealed that intervention teachers individualized instruction more precisely than did comparison teachers. Importantly, the more precisely children received recommended amounts of instruction, the stronger was their literacy skill growth. Results provide strong evidence of child X instruction interaction effects on literacy outcomes. PMID:19236394

To describe the progression and distribution of federal funds for programs and activities that fall within the scope of the guidelines of the Brazilian National Policy on Food and Nutrition Security (PNSAN) in the period from 2004 to 2010. This descriptive study used data from the Transparency Website maintained by the Brazilian Public Sector Internal Control Office. Search results were exported to Excel spreadsheets. To determine the resources allocated to food security initiatives, a database was set up containing all actions developed by the federal government between 2004 and 2010. This database was reviewed and the actions that were not related to PNSAN were discarded. The annual amounts obtained were corrected by the Consumer Price Index and updated for the year 2010. Since actions are part of specific programs, the sum of the resources allocated for all the actions of a program amounted to the resources invested in the program as a whole. The programs were then prioritized according to the amount of resources received in 2010. Of the 5 014 actions receiving federal funds in the study period, 814 were related to PNSAN (229 programs). There was growth in resources allocated for PNSAN programs, reaching US$ 15 billion in 2010 (an 82% increase over the previous year). The largest amount was invested in Bolsa Família, a cash transfer program. Ten programs received 90% of the funds, of which five were linked to food production processes. The amount of resources invested in the PNSAN and in actions and programs that promote food and nutrition security is increasing in Brazil.

Variations in levels of care between nursing home patients in a public health care system

PubMed Central

2014-01-01

Background Within the setting of a public health service we analyse the distribution of resources between individuals in nursing homes funded by global budgets. Three questions are pursued. Firstly, whether there are systematic variations between nursing homes in the level of care given to patients. Secondly, whether such variations can be explained by nursing home characteristics. And thirdly, how individual need-related variables are associated with differences in the level of care given. Methods The study included 1204 residents in 35 nursing homes and extra care sheltered housing facilities. Direct time spent with patients was recorded. In average each patient received 14.8 hours direct care each week. Multilevel regression analysis is used to analyse the relationship between individual characteristics, nursing home characteristics and time spent with patients in nursing homes. The study setting is the city of Trondheim, with a population of approximately 180 000. Results There are large variations between nursing homes in the total amount of individual care given to patients. As much as 24 percent of the variation of individual care between patients could be explained by variation between nursing homes. Adjusting for structural nursing home characteristics did not substantially reduce the variation between nursing homes. As expected a negative association was found between individual care and case-mix, implying that at nursing home level a more resource demanding case-mix is compensated by lowering the average amount of care. At individual level ADL-disability is the strongest predictor for use of resources in nursing homes. For the average user one point increase in ADL-disability increases the use of resources with 27 percent. Conclusion In a financial reimbursement model for nursing homes with no adjustment for case-mix, the amount of care patients receive does not solely depend on the patients’ own needs, but also on the needs of all the other residents.

We examined the effectiveness of tranexamic acid in preventing intraoperative blood loss during major cardiac surgery. Out of initial 81 patients undergoing major cardiac surgery (both coronary artery bypass and valve repair procedures) at our teaching hospital, sixty-seven patients were selected for this study. We compared estimated blood loss, decrease in percent hemoglobin and hematocrit following surgery between two groups of patients (none of them received any blood product during surgery), one group receiving no tranexamic acid (n=17) and another group receiving tranexamic acid (n=25). In the second study, we combined these patients with patients receiving modest amounts of blood products (1-2 unit) and compared these parameters between two groups of patients (25 patients received no tranexamic acid, 42 patients received tranexamic acid). In patients who received no blood product during surgery, those who received no tranexamic acid showed statistically significant (independent t-test two tailed at p <0.05) reduced estimated blood loss (mean: 713.5 mL, SD: 351.6, n=17) compared to those who received tranexamic acid (mean: 987.2 mL, SD: 459.9, n=25). We observed similar results when the patients receiving no blood products and patients receiving modest amount of blood products were combined based on the use of tranexamic acid or not. No statistically significant difference was observed in percent reduced hemoglobin or hematocrit following surgery in any group of patients. We conclude that intraoperative antifibrinolytic therapy with tranexamic acid does not reduce intraoperative blood loss during major cardiac surgery which contradicts popular belief. © 2017 by the Association of Clinical Scientists, Inc.

Economic Returns to Investment in AIDS Treatment in Low and Middle Income Countries

Since the early 2000s, aid organizations and developing country governments have invested heavily in AIDS treatment. By 2010, more than five million people began receiving antiretroviral therapy (ART) – yet each year, 2.7 million people are becoming newly infected and another two million are dying without ever having received treatment. As the need for treatment grows without commensurate increase in the amount of available resources, it is critical to assess the health and economic gains being realized from increasingly large investments in ART. This study estimates total program costs and compares them with selected economic benefits of ART, for the current cohort of patients whose treatment is cofinanced by the Global Fund to Fight AIDS, Tuberculosis and Malaria. At end 2011, 3.5 million patients in low and middle income countries will be receiving ART through treatment programs cofinanced by the Global Fund. Using 2009 ART prices and program costs, we estimate that the discounted resource needs required for maintaining this cohort are $14.2 billion for the period 2011–2020. This investment is expected to save 18.5 million life-years and return $12 to $34 billion through increased labor productivity, averted orphan care, and deferred medical treatment for opportunistic infections and end-of-life care. Under alternative assumptions regarding the labor productivity effects of HIV infection, AIDS disease, and ART, the monetary benefits range from 81 percent to 287 percent of program costs over the same period. These results suggest that, in addition to the large health gains generated, the economic benefits of treatment will substantially offset, and likely exceed, program costs within 10 years of investment.

[Income reduction due to sickness benefits--when does sickness make you poor?].

PubMed

Mielck, A; Huber, C A

2005-01-01

When absent from work due to sickness, most employees in Germany receive continued pay from their employer for six weeks. After this period, sick employees receive sickness benefits from their Statutory Sickness Fund. These sickness benefits are calculated in a rather complicated way as a percentage of gross and net salary. The paper focuses on two questions that have rarely been studied: which income groups show a particularly large difference between net salary and net sickness benefits? Which income groups move below the poverty line after receiving sickness benefits? We calculated how much sickness benefit is actually paid to the insured, for different income and tax groups. The definition for the poverty line is outlined as well. Due to methodological difficulties, the comparison between sickness benefits and poverty must be confined to single-person households. In the income groups chosen here (gross salary up to 4000 Euro per month), net sickness benefits amount to about 77 % of net salary, for all insured. Financial problems can mainly be expected for the lower and the upper income groups. Expressed in absolute terms, the upper income groups experience a large reduction in net income. The lower income groups come close to the poverty line or fall below it. Sickness benefits provide income in case of sickness; this is an important achievement of social policy. However, we should study the financial burden which sickness benefits could have for the insured. More in-depth analyses would require data that are not yet available (e. g. on the number of insured per income group and the income of other household members). The analyses presented here already show that sickness benefits could lead to severe financial problems for at least some insured. They point to the need for more studies in this neglected field.

2015-12-21

Between September 10 and 17, 2013, New Mexico and Colorado received a historically large amount of precipitation (Figure 1). This report assesses the damage caused by flooding along with estimated costs to repair the damage at Los Alamos National Laboratory (the Laboratory) on the Pajarito Plateau. Los Alamos County, New Mexico, received between 200% and 600% of the normal precipitation for this time period (Figure 2), and the Laboratory received approximately 450% percent of its average precipitation for September (Figure 3). As a result, the Laboratory was inundated with rain, including the extremely large, greater-than-1000-yr return period event that occurredmore » between September 12 and 13 (Table 1). With saturated antecedent soil conditions from the September 10 storm, when the September 12 to September 13 storm hit, the flooding was disastrous to the Laboratory’s environmental infrastructure, including access roads, gage stations, watershed controls, control measures installed under the National Pollutant Discharge Elimination System Permit (hereafter, the Individual Permit), and groundwater monitoring wells (Figures 4 through 21). From September 16 to October 1, 2013, the Laboratory completed field assessments of environmental infrastructure and generated descriptions and estimates of the damage, which are presented in spreadsheets in Attachments 1 to 4 of this report. Section 2 of this report contains damage assessments by watershed, including access roads, gage stations, watershed controls, and control measures installed under the Individual Permit. Section 3 contains damage assessments of monitoring wells by the groundwater monitoring groups as established in the Interim Facility-Wide Groundwater Monitoring Plan for Monitoring Year 2014. Section 4 addresses damage and loss of automated samplers. Section 5 addresses sediment sampling needs, and Section 6 is the summary of estimated recovery costs from the significant rain and flooding during September 2013.« less

Silicon CMOS optical receiver circuits with integrated thin-film compound semiconductor detectors

While many circuit designers have tackled the problem of CMOS digital communications receiver design, few have considered the problem of circuitry suitable for an all CMOS digital IC fabrication process. Faced with a high speed receiver design the circuit designer will soon conclude that a high speed analog-oriented fabrication process provides superior performance advantages to a digital CMOS process. However, for applications where there are overwhelming reasons to integrate the receivers on the same IC as large amounts of conventional digital circuitry, the low yield and high cost of the exotic analog-oriented fabrication is no longer an option. The issues that result from a requirement to use a digital CMOS IC process cut across all aspects of receiver design, and result in significant differences in circuit design philosophy and topology. Digital ICs are primarily designed to yield small, fast CMOS devices for digital logic gates, thus no effort is put into providing accurate or high speed resistances, or capacitors. This lack of any reliable resistance or capacitance has a significant impact on receiver design. Since resistance optimization is not a prerogative of the digital IC process engineer, the wisest option is thus to not use these elements, opting instead for active circuitry to replace the functions normally ascribed to resistance and capacitance. Depending on the application receiver noise may be a dominant design constraint. The noise performance of CMOS amplifiers is different than bipolar or GaAs MESFET circuits, shot noise is generally insignificant when compared to channel thermal noise. As a result the optimal input stage topology is significantly different for the different technologies. It is found that, at speeds of operation approaching the limits of the digital CMOS process, open loop designs have noise-power-gain-bandwidth tradeoff performance superior to feedback designs. Furthermore, the lack of good resisters and capacitors complicates the use of feedback circuits. Thus feedback is generally not used in the front-end of our digital process CMOS receivers.

Bioaccumulation of decamethylcyclopentasiloxane in perch in Swedish lakes.

Decamethylcyclopentasiloxane (D5), a high production volume chemical used in personal care products, enters the environment both via air and sewage treatment plant (STP) recipients. It has been found in fish, and there is concern that it may be a bioaccumulative substance. In this work D5 was analyzed in perch from six Swedish lakes that did not receive STP effluent, and in perch and sediment from six lakes that received STP effluent. In the lakes receiving the STP effluent, the D5 concentrations in sediment varied over three orders of magnitude and were correlated with the number of persons connected to the STP normalized to the surface area of the receiving body. In the lakes not receiving effluent, the D5 levels in perch were all below the LOQ, while D5 was above the LOQ in almost all perch from lakes that received effluent. The D5 concentrations in perch and sediment from the lakes receiving STP effluent were correlated. This shows that STP effluent is a much more important source of D5 to aquatic ecosystems than atmospheric deposition, and that the risk of adverse effects of D5 on aquatic life will be greatest in small recipients receiving large amounts of STP effluent. The bioaccumulation of D5 was compared to that of PCB 180 on the basis of multimedia bioaccumulation factors (mmBAFs), which describe the fraction of the contaminant present in the whole aquatic environment (i.e. water and surface sediment) that is transferred to the fish. In four of the six lakes the mmBAF of D5 was >0.3 of the mmBAF of PCB 180. Given that PCB 180 is a known highly bioaccumulative chemical, this indicates that the bioaccumulation of D5 in perch is considerable. Copyright © 2012 Elsevier Ltd. All rights reserved.

Music therapy is a common discretionary service offered within hospice; however, there are critical gaps in understanding the effects of music therapy on hospice quality indicators, such as family satisfaction with care. The purpose of this study was to examine whether music therapy affected family perception of patients' symptoms and family satisfaction with hospice care. This was a retrospective, cross-sectional analysis of electronic medical records from 10,534 cancer patients cared for between 2006 and 2010 by a large national hospice. Logistic regression was used to estimate the effect of music therapy using propensity scores to adjust for non-random assignment. Overall, those receiving music therapy had higher odds of being female, having longer lengths of stay, and receiving more services other than music therapy, and lower odds of being married/partnered or receiving home care. Family satisfaction data were available for 1495 (14%) and were more likely available if the patient received music therapy (16% vs. 12%, P < 0.01). There were no differences in patient pain, anxiety, or overall satisfaction with care between those receiving music therapy vs. those not. Patients who received music therapy were more likely to report discussions about spirituality (odds ratio [OR] = 1.59, P = 0.01), had marginally less trouble breathing (OR = 0.77, P = 0.06), and were marginally more likely to receive the right amount of spiritual support (OR = 1.59, P = 0.06). Music therapy was associated with perceptions of meaningful spiritual support and less trouble breathing. The results provide preliminary data for a prospective trial to optimize music therapy interventions for integration into clinical practice.

PEPFAR Funding Associated With An Increase In Employment Among Males in Ten Sub-Saharan African Countries.

2015-06-01

The President's Emergency Plan for AIDS Relief (PEPFAR) has provided billions of US tax dollars to expand HIV treatment, care, and prevention programs in sub-Saharan Africa. This investment has generated significant health gains, but much less is known about PEPFAR's population-level economic effects. We used a difference-in-differences approach to compare employment trends between ten countries that received a large amount of PEPFAR funding (focus countries) and eleven countries that received little or no funding (control countries). We found that PEPFAR was associated with a 13 percent differential increase in employment among males in focus countries, compared to control countries. However, we observed no change in employment among females. In addition, we found that increasing PEPFAR per capita funding by $100 was associated with a 9.1-percentage-point increase in employment among males. This rise in employment generates economic benefits equal to half of PEPFAR's cost. These findings suggest that PEPFAR's economic impact should be taken into account when making aid allocation decisions. Project HOPE—The People-to-People Health Foundation, Inc.

In the past three years, we followed the work plan as we suggested in the proposal and made every efforts to fulfill the project objectives. Based on our large amount of creative and productive work, including both of experimental and theoretic aspects, we received important technical breakthrough on naphthenic acid removal process and obtained deep insight on catalytic decarboxylation chemistry. In detail, we established an integrated methodology to serve for all of the experimental and theoretical work. Our experimental investigation results in discovery of four type effective catalysts to the reaction of decarboxylation of model carboxylic acid compounds. The adsorptionmore » experiment revealed the effectiveness of several solid materials to naphthenic acid adsorption and acidity reduction of crude oil, which can be either natural minerals or synthesized materials. The test with crude oil also received promising results, which can be potentially developed into a practical process for oil industry. The theoretical work predicted several possible catalytic decarboxylation mechanisms that would govern the decarboxylation pathways depending on the type of catalysts being used. The calculation for reaction activation energy was in good agreement with our experimental measurements.« less

To estimate the association of 1 activity of the Prevention and Public Health Fund with hospital bloodstream infections and calculate the return on investment (ROI). The activity was funded for 1 year (2013). A difference-in-differences specification evaluated hospital standardized infection ratios (SIRs) before funding allocation (years 2011 and 2012) and after funding allocation (years 2013 and 2014) in the 15 US states that received the funding compared with hospital SIRs in states that did not receive the funding. We estimated the association of the funded public health activity with SIRs for bloodstream infections. We calculated the ROI by dividing cost offsets from infections averted by the amount invested. The funding was associated with a 33% (P < .05) reduction in SIRs and an ROI of $1.10 to $11.20 per $1 invested in the year of funding allocation (2013). In 2014, after the funding stopped, significant reductions were no longer evident. This activity was associated with a reduction in bloodstream infections large enough to recoup the investment. Public health funding of carefully targeted areas may improve health and reduce health care costs.

Better quality of life in patients offered financial incentives for taking anti-psychotic medication: Linked to improved adherence or more money?

2016-08-01

In a randomised controlled trial, patients were offered financial incentives to improve their adherence to anti-psychotic maintenance medication. Compared to a control group without the incentives, they had an improved adherence and also better subjective quality of life (SQOL) after 1 year. This paper explores the question as to whether this improvement in SQOL was associated with the amount of money received or with the improved adherence itself. A secondary analysis was performed using data of the experimental group in the trial. Adherence was assessed as the percentage of all prescribed long-acting anti-psychotic injections that were taken by the patient. In regression models, we tested whether changes in medication adherence and/or the amount of incentives received over the 12-month period was associated with SQOL, as rated on the DIALOG scale. Adherence changed from 68.49 % at baseline to 88.23 % (mean difference in adherence = 19.59 %, SD = 17.52 %). The total amount of incentives received within the 1-year study period varied between £75 and £735, depending on the treatment cycle and the number of long-acting injections taken. Improvement in adherence was found to be a significant predictor of better subjective quality of life (β = 0.014, 95 % CI 0.003-0.025, p = 0.014), whilst the amount of incentives received was not (β = 0.0002, 95 % CI -0.002 to 0.002, p = 0.818). Improved medication adherence is associated with a more favourable SQOL. This underlines the clinical relevance of improved adherence in response to financial incentives in this patient group.

The Influence of Different Kinds of Incentives on Decision-Making and Cognitive Control in Adolescent Development: A Review of Behavioral and Neuroscientific Studies

PubMed Central

Kray, Jutta; Schmitt, Hannah; Lorenz, Corinna; Ferdinand, Nicola K.

2018-01-01

A number of recent hypothetical models on adolescent development take a dual-systems perspective and propose an imbalance in the maturation of neural systems underlying reward-driven and control-related behavior. In particular, such models suggest that the relative dominance of the early emerging subcortical reward system over the later emerging prefrontal-guided control system leads to higher risk-taking and sensation-seeking behavior in mid-adolescents. Here, we will review recent empirical evidence from behavioral and neuroscientific studies examining interactions between these systems and showing that empirical evidence in support for the view of a higher sensitivity to rewards in mid-adolescents is rather mixed. One possible explanation for this may be the use of different kinds and amounts of incentives across studies. We will therefore include developmental studies comparing the differential influence of primary and secondary incentives, as well as those investigating within the class of secondary incentives the effects of monetary, cognitive, or social incentives. We hypothesized that the value of receiving sweets or sours, winning or losing small or large amounts of money, and being accepted or rejected from a peer group may also changes across development, and thereby might modulate age differences in decision-making and cognitive control. Our review revealed that although developmental studies directly comparing different kinds of incentives are rather scarce, results of various studies rather consistently showed only minor age differences in the impact of incentives on the behavioral level. In tendency, adolescents were more sensitive to higher amounts of incentives and larger uncertainty of receiving them, as well as to social incentives such as the presence of peers observing them. Electrophysiological studies showed that processing efficiency was enhanced during anticipation of incentives and receiving them, irrespective of incentive type. Again, we found no strong evidence for interactions with age across studies. Finally, functional brain imaging studies revealed evidence for overlapping brain regions activated during processing of primary and secondary incentives, as well as social and non-social incentives. Adolescents recruited similar reward-related and control-related brain regions as adults did, but to a different degree. Implications for future research will be discussed. PMID:29875720

Medicaid and family wealth transfer.

Lee, Jinkook; Kim, Hyungsoo; Tanenbaum, Sandra

2006-02-01

This study examines whether the relationship between making familial wealth transfers and becoming a Medicaid recipient sheds light on the current debate about Medicaid estate planning, whereby some elders transfer their assets to their families to qualify for Medicaid. Using the Health and Retirement Study, we tracked a national sample of community-based elders who did not receive Medicaid at the 1993 baseline interview but became Medicaid recipients during a 10-year time period and examined wealth transfers for these new Medicaid beneficiaries. Among elders aged 70 or older who did not receive Medicaid in 1993, 16.4% became Medicaid recipients over 10 years. Among these new Medicaid recipients, 17.9% transferred their wealth to family members before receiving Medicaid benefits, with an average transfer amount of $8,507 during the 2 years prior to receiving Medicaid benefits. In addition, 15.2% of community-residing elders entered a nursing home during the 10-year period, and 26.3% of these were covered by Medicaid. Of these new Medicaid recipients living in nursing homes, 12.6% transferred wealth to their families in the mean amount of $4,112. Familial wealth transfers do occur before changes in Medicaid eligibility in a small, but nontrivial, number of cases, but the amount transferred is modest, especially among nursing home residents. This finding implies that policies to reduce Medicaid long-term-care expenditures by limiting such transfers may not be very effective.

Mono-static GPR without transmitting anything for pavement damage inspection: interferometry by auto-correlation applied to mobile phone signals

NASA Astrophysics Data System (ADS)

Feld, R.; Slob, E. C.; Thorbecke, J.

2015-12-01

Creating virtual sources at locations where physical receivers have measured a response is known as seismic interferometry. A much appreciated benefit of interferometry is its independence of the actual source locations. The use of ambient noise as actual source is therefore not uncommon in this field. Ambient noise can be commercial noise, like for example mobile phone signals. For GPR this can be useful in cases where it is not possible to place a source, for instance when it is prohibited by laws and regulations. A mono-static GPR antenna can measure ambient noise. Interferometry by auto-correlation (AC) places a virtual source on this antenna's position, without actually transmitting anything. This can be used for pavement damage inspection. Earlier work showed very promising results with 2D numerical models of damaged pavement. 1D and 2D heterogeneities were compared, both modelled in a 2D pavement world. In a 1D heterogeneous model energy leaks away to the sides, whereas in a 2D heterogeneous model rays can reflect and therefore still add to the signal reconstruction (see illustration). In the first case the amount of stationary points is strictly limited, while in the other case the amount of stationary points is very large. We extend these models to a 3D world and optimise an experimental configuration. The illustration originates from the journal article under submission 'Non-destructive pavement damage inspection by mono-static GPR without transmitting anything' by R. Feld, E.C. Slob, and J.W. Thorbecke. (a) 2D heterogeneous pavement model with three irregular-shaped misalignments between the base and subbase layer (marked by arrows). Mono-antenna B-scan positions are shown schematically. (b) Ideal output: a real source at the receiver's position. The difference w.r.t. the trace found in the middle is shown. (c) AC output: a virtual source at the receiver's position. There is a clear overlap with the ideal output.

Conflicts of interest of editors of medical journals

Minhajuddin, Abu

2018-01-01

Background Almost all medical journals now require authors to publicly disclose conflicts of interests (COI). The same standard and scrutiny is rarely employed for the editors of the journals although COI may affect editorial decisions. Methods We conducted a retrospective observational study to determine the prevalence and magnitude of financial relationships among editors of 60 influential US medical journals (10 each for internal medicine and five subspecialties: cardiology, gastroenterology, neurology, dermatology and allergy & immunology). Open Payments database was reviewed to determine the percentage of physician editors receiving payments and the nature and amount of these payments. Findings 703 unique physician editors were included in our analysis. 320/703 (46%) received 8659 general payments totaling $8,120,562. The median number of payments per editor was 9 (IQR 3–26) and the median amount per payment was $91 (IQR $21–441). The median total payment received by each editor in one year was $4,364 (IQR $319–23,143). 152 (48%) editors received payments more than $5,000 in a year, a threshold considered significant by the National Institutes of Health. COI policies for editors were available for 34/60 (57%) journals but only 7/34 (21%) publicly reported the disclosures and only 2 (3.%) reported the dollar amount received. Interpretation A significant number of editors of internal medicine and subspecialty medical journals have financial COI and very few are publicly disclosed. Specialty journal editors have more COI compared to general medicine journal editors. Current policies for disclosing COI for editors are inconsistent and do not comply with the recommended standards. PMID:29775468

Falls among old people is a well-documented phenomenon; however, falls among people living in the community and receiving home help services have been under-researched. The aim of this study was to investigate the incidence, including possible seasonal variation, circumstances and injuries related to falls among community living home help receivers, and to investigate whether fall incidence is associated with the type and amount of home help services received. Prospective cohort study. All 614 persons aged 65 and over who were living in a particular northern Swedish community and receiving municipality home help were included. Data on age, sex and home help service use were collected from home help service records, and falls were reported by staff on report forms specifically designed for the study. Results. A total number of 264 falls were recorded among 122 participants. The overall fall incidence was 626 per 1,000 PY, and incidence rate ratios were significantly correlated to the total amount of services used (p<0.001), as well as to the degree of help for I-ADL needs (p<0.001), P-ADL needs (p<0.001) and escort service (p=0.007). The proportion of falls reported as resulting in injury was 33%. The monthly fall incidence was significantly associated to daylight photoperiod, however it was not associated to temperature. Fall incidence among home help receivers aged 65 and over seems correlated to the amount of services they receive. This is probably explained by the fact that impairments connected to ADL limitations and home help needs also are connected to an increased risk of falls. This implies that fall prevention should be considered when planning home help care for old people with ADL limitations. Further research on the connection between daylight photoperiod and fall incidence in populations at different latitudes is needed.

Solar power satellite—Life-cycle energy recovery considerations

NASA Astrophysics Data System (ADS)

Weingartner, S.; Blumenberg, J.

1995-05-01

The construction, in-orbit installation and maintenance of a solar power satellite (SPS) will demand large amounts of energy. As a minimum requirement for an energy effective power satellite it is asked that this amount of energy be recovered. The energy effectiveness in this sense resulting in a positive net energy balance is a prerequisite for a cost-effective power satellite. This paper concentrates on life-cycle energy recovery instead of monetary aspects. The trade-offs between various power generation systems (different types of solar cells, solar dynamic), various construction and installation strategies (using terrestrial or extra-terrestrial resources) and the expected/required lifetime of the SPS are reviewed. The presented work is based on a 2-year study performed at the Technical University of Munich. The study showed that the main energy which is needed to make a solar power satellite a reality is required for the production of the solar power plant components (up to 65%), especially for the solar cell production. Whereas transport into orbit accounts in the order of 20% and the receiving station on Earth (rectenna) requires in the order of 15% of the total energy investment. The energetic amortization time, i.e. the time the SPS has to be operational to give back the amount of energy which was needed for its production, installation and operation, is in the order of two years.

Aims Vanadium is currently undergoing clinical trials as an oral drug in patients with noninsulin-dependent diabetes mellitus. Furthermore, vanadium occurs in elevated concentrations in the blood of patients receiving intravenous albumin solutions containing large amounts of the metal ion as an impurity. The present study was performed to examine the pharmacokinetics of vanadium in humans following a single intravenous (i.v.) dose of a commercial albumin solution containing a high amount of vanadium. Methods The study was conducted in five healthy volunteer subjects who received intravenously 90 ml of a commercial 20% albumin infusion solution containing 47.6 µg vanadium as an impurity. Vanadium concentrations in serum and urine were determined by electrothermal atomic absorption spectrometry. Results Vanadium serum concentrations after i.v. administration were measured for 31 days. The data could be fitted by a triexponential function corresponding formally to a three-compartment model. There was an initial rapid decrease in serum concentrations with half-lives of 1.2 and 26 h. This was followed by a long-terminal half-life time of 10 days. The terminal phase accounted for about 80% of the total area under the serum concentration-time curve (AUC). The mean apparent volume of distribution of the central compartment was found to be 10 l. The volume of distribution at steady state was 54 l, and total clearance was 0.15 l h−1. Vanadium was mainly excreted by the kidneys. About 52% of the dose was recovered in the urine after 12 days. Conclusions This study provides data on vanadium pharmacokinetics in healthy humans.

Can nutritional supplements help mentally retarded children? an exploratory study.

1981-01-01

To explore the hypothesis that mental retardations are in part genetotrophic diseases (diseases in which the genetic pattern of the afflicted individual requires an augmented supply of one or more nutrients such that when these nutrients are adequately supplied the disease is ameliorated), we carried out a partially double-blind experiment with 16 retarded children (initial IQs, approximately 17-70) of school age who wee given nutritional supplements or placebos during a period of 8 months. The supplement contained 8 minerals in moderate amounts and 11 vitamins, mostly in relatively large amounts. During the first 4- month period (double-blind) the 5 children who received supplements increased their average IQ by 5.0-9.6, depending on the investigator, whereas the 11 subjects given placebos showed negligible change. The difference between these two groups is statistically significant (P less than 0.05). During the second period, the subjects who had been given placebos in the first study received supplements; they showed an average IQ increase of at least 10.2, a highly significant gain (P less than 0.001). Three of the five subjects who were given supplements for both periods showed additional IQ gains during the second 4 months. Three of four children with Down syndrome gained between 10 and 25 units in IQ and also showed physical changes toward normal. Other evidence suggests that the supplement improved visual acuity in two children and increased growth rates. These results support the hypothesis that mental retardations are in part genetotrophic in origin. PMID:6454137

Demonstrate Scale-up Procedure for Glass Composite Material (GCM) for Incorporation of Iodine Loaded AgZ.

Nenoff, Tina M.; Garino, Terry J.; Croes, Kenneth James

2015-07-01

Two large size Glass Composite Material (GCM) waste forms containing AgI-MOR were fabricated. One contained methyl iodide-loaded AgI-MOR that was received from Idaho National Laboratory (INL, Test 5, Beds 1 – 3) and the other contained iodine vapor loaded AgIMOR that was received from Oak Ridge National Laboratory (ORNL, SHB 2/9/15 ). The composition for each GCM was 20 wt% AgI-MOR and 80 wt% Ferro EG2922 low sintering temperature glass along with enough added silver flake to prevent any I2 loss during the firing process. The silver flake amounts were 1.2 wt% for the GCM with the INL AgI-MOR andmore » 3 wt% for the GCM contained the ORNL AgI-MOR. The GCMs, nominally 100 g, were first uniaxially pressed to 6.35 cm (2.5 inch) diameter disks then cold isostatically pressed, before firing in air to 550°C for 1hr. They were cooled slowly (1°C/min) from the firing temperature to avoid any cracking due to temperature gradients. The final GCMs were ~5 cm in diameter (~2 inches) and non-porous with densities of ~4.2 g/cm³. X-ray diffraction indicated that they consisted of the amorphous glass phase with small amounts of mordenite and AgI. Furthermore, the presence of the AgI was confirmed by X-ray fluorescence. Methodology for the scaled up production of GCMs to 6 inch diameter or larger is also presented.« less

A prospective survey of nutritional support practices in intensive care unit patients: what is prescribed? What is delivered?

To assess the amount of nutrients delivered, prescribed, and required for critically ill patients and to identify the reasons for discrepancies between prescriptions and requirements and between prescriptions and actual delivery of nutrition. Prospective cohort study. Twelve-bed medical intensive care unit in a university-affiliated general hospital. Fifty-one consecutive patients, receiving nutritional support either enterally or intravenously for > or = 2 days. We followed patients for the first 14 days of nutritional delivery. The amount of calories prescribed and the amount actually delivered were recorded daily and compared with the theoretical energy requirements. A combined regimen of enteral and parenteral nutrition was administered on 58% of the 484 nutrition days analyzed, and 63.5% of total caloric intake was delivered enterally. Seventy-eight percent of the mean caloric amount required was prescribed, and 71% was effectively delivered. The amount of calories actually delivered compared with the amount prescribed was significantly lower in enteral than in parenteral administration (86.8% vs. 112.4%, p < .001). Discrepancies between prescription and delivery of enterally administered nutrients were attributable to interruptions caused by digestive intolerance (27.7%, mean daily wasted volume 641 mL), airway management (30.8%, wasted volume 745 mL), and diagnostic procedures (26.6%, wasted volume 567 mL). Factors significantly associated with a low prescription rate of nutritional support were the administration of vasoactive drugs, central venous catheterization, and the need for extrarenal replacement. An inadequate delivery of enteral nutrition and a low rate of nutrition prescription resulted in low caloric intake in our intensive care unit patients. A large volume of enterally administered nutrients was wasted because of inadequate timing in stopping and restarting enteral feeding. The inverse correlation between the prescription rate of nutrition and the intensity of care required suggests that physicians need to pay more attention to providing appropriate nutritional support for the most severely ill patients.

Using a communication audit to improve communication on clinical placement in pre-registration nursing.

2005-02-01

This article describes a novel communication audit conducted with those concerned with the practice placements of pre-registration Nursing students. The study, uniquely, addressed all who were involved in communication concerning placement in what is described as an organisational analysis. The aim of the audit was to identify levels of satisfaction and dissatisfaction with present communication processes and to identify points for improvement. The audit used the Hogard-Barker Communication Audit of Practice a customized version of a well established tool, devised to cover issues relevant to practice placements. A key feature of the tool is the opportunity for participants to identify the amount of communication they are receiving on particular topics and issues against the amount they would like to receive. Participants in the audit included students, assessor mentors, ward managers, clinical facilitators and link tutors. Overall there was considerable dissatisfaction with what was perceived to be the insufficient amount of communication received on a number of topics including allocations, the curriculum, students' learning outcomes and commitments in terms of college work. In addition to identifying points for improvement the audit provides a baseline against which progress can be assessed through a future audit.

High-resolution Hydrodynamic Simulation of Tidal Detonation of a Helium White Dwarf by an Intermediate Mass Black Hole

NASA Astrophysics Data System (ADS)

Tanikawa, Ataru

2018-05-01

We demonstrate tidal detonation during a tidal disruption event (TDE) of a helium (He) white dwarf (WD) with 0.45 M ⊙ by an intermediate mass black hole using extremely high-resolution simulations. Tanikawa et al. have shown tidal detonation in results of previous studies from unphysical heating due to low-resolution simulations, and such unphysical heating occurs in three-dimensional (3D) smoothed particle hydrodynamics (SPH) simulations even with 10 million SPH particles. In order to avoid such unphysical heating, we perform 3D SPH simulations up to 300 million SPH particles, and 1D mesh simulations using flow structure in the 3D SPH simulations for 1D initial conditions. The 1D mesh simulations have higher resolutions than the 3D SPH simulations. We show that tidal detonation occurs and confirm that this result is perfectly converged with different space resolution in both 3D SPH and 1D mesh simulations. We find that detonation waves independently arise in leading parts of the WD, and yield large amounts of 56Ni. Although detonation waves are not generated in trailing parts of the WD, the trailing parts would receive detonation waves generated in the leading parts and would leave large amounts of Si group elements. Eventually, this He WD TDE would synthesize 56Ni of 0.30 M ⊙ and Si group elements of 0.08 M ⊙, and could be observed as a luminous thermonuclear transient comparable to SNe Ia.

Comparison of TID Effects in Space-Like Variable Dose Rates and Constant Dose Rates

NASA Technical Reports Server (NTRS)

Harris, Richard D.; McClure, Steven S.; Rax, Bernard G.; Evans, Robin W.; Jun, Insoo

2008-01-01

The degradation of the LM193 dual voltage comparator has been studied at different TID dose rate profiles, including several different constant dose rates and a variable dose rate that simulates the behavior of a solar flare. A comparison of results following constant dose rate vs. variable dose rates is made to explore how well the constant dose rates used for typical part testing predict the performance during a simulated space-like mission. Testing at a constant dose rate equal to the lowest dose rate seen during the simulated flare provides an extremely conservative estimate of the overall amount of degradation. A constant dose rate equal to the average dose rate is also more conservative than the variable rate. It appears that, for this part, weighting the dose rates by the amount of total dose received at each rate (rather than the amount of time at each dose rate) results in an average rate that produces an amount of degradation that is a reasonable approximation to that received by the variable rate.

The response of East Asian monsoon to the precessional cycle

NASA Astrophysics Data System (ADS)

Lee, J. E.

2017-12-01

The oxygen isotopic composition of cave speleothems exhibits a large amplitude change following the insolation, particularly the precessional cycle. Whether speleothem d18O reflects local precipitation amount, however, has been questioned by alternative hypotheses: (1) d18O reflects upstream Indian monsoon precipitation, which influences the isotopic composition of the input vapor to East Asia, and (2) the isotopic composition of pre-monsoon and monsoon exhibits a large difference, and the seasonality of precipitation may have shifted in response to insolation. Motivated the fact that the magnitude of Asian monsoon d18O was not reproduced by most climate models, here I show new results, using the fully coupled GFDL model, that precipitation increases when the northern hemisphere receives more summer insolation, similar to the original claim. I argue that previous models do not produce enough rainfall during the monsoon season, possibly because the westerly jet is located too north in relation to the Tibetan Plateau during the monsoon season. I conclude that Asian monsoon intensity probably increases with increasing insolation there, given a large change in speleothem d18O. My next step will be testing this hypothesis after incorporating isotopes into the GFDL model.

Synthesis of Monolayer MoS2 by Chemical Vapor Deposition

Withanage, Sajeevi; Lopez, Mike; Dumas, Kenneth; Jung, Yeonwoong; Khondaker, Saiful

Finite and layer-tunable band gap of transition metal dichalcogenides (TMDs) including molybdenum disulfide (MoS2) are highlighted over the zero band gap graphene in various semiconductor applications. Weak interlayer Van der Waal bonding of bulk MoS2 allows to cleave few to single layer MoS2 using top-down methods such as mechanical and chemical exfoliation, however few micron size of these flakes limit MoS2 applications to fundamental research. Bottom-up approaches including the sulfurization of molybdenum (Mo) thin films and co-evaporation of Mo and sulfur precursors received the attention due to their potential to synthesize large area. We synthesized monolayer MoS2 on Si/SiO2 substrates by atmospheric pressure Chemical Vapor Deposition (CVD) methods using sulfur and molybdenum trioxide (MoO3) as precursors. Several growth conditions were tested including precursor amounts, growth temperature, growth time and flow rate. Raman, photoluminescence (PL) and atomic force microscopy (AFM) confirmed monolayer islands merging to create large area were observed with grain sizes up to 70 μm without using any seeds or seeding promoters. These studies provide in-depth knowledge to synthesize high quality large area MoS2 for prospective electronics applications.

A sharp and flat section of the core-mantle boundary

USGS Publications Warehouse

Vidale, J.E.; Benz, H.M.

1992-01-01

THE transition zone between the Earth's core and mantle plays an important role as a boundary layer for mantle and core convection1. This zone conducts a large amount of heat from the core to the mantle, and contains at least one thermal boundary layer2,3; the proximity of reactive silicates and molten iron leads to the possibility of zones of intermediate composition4. Here we investigate one region of the core-mantle boundary using seismic waves that are converted from shear to compressional waves by reflection at the boundary. The use of this phase (known as ScP), the large number of receiving stations, and the large aperture of our array all provide higher resolution than has previously been possible5-7. For the 350-km-long section of the core-mantle boundary under the northeast Pacific sampled by the reflections, the local boundary topography has an amplitude of less than 500 m, no sharp radial gradients exist in the 400 km above the boundary, and the mantle-lo-core transition occurs over less than 1 km. The simplicity of the structure near and above the core-mantle boundary argues against chemical heterogeneity at the base of the mantle in this location.

ARGOS is the Laser Guide Star and Wavefront sensing facility for the Large Binocular Telescope. With first laser light on sky in 2013, the system is currently undergoing commissioning at the telescope. We present the overall status and design, as well as first results on sky. Aiming for a wide field ground layer correction, ARGOS is designed as a multi- Rayleigh beacon adaptive optics system. A total of six powerful pulsed lasers are creating the laser guide stars in constellations above each of the LBTs primary mirrors. With a range gated detection in the wavefront sensors, and the adaptive correction by the deformable secondary's, we expect ARGOS to enhance the image quality over a large range of seeing conditions. With the two wide field imaging and spectroscopic instruments LUCI1 and LUCI2 as receivers, a wide range of scientific programs will benefit from ARGOS. With an increased resolution, higher encircled energy, both imaging and MOS spectroscopy will be boosted in signal to noise by a large amount. Apart from the wide field correction ARGOS delivers in its ground layer mode, we already foresee the implementation of a hybrid Sodium with Rayleigh beacon combination for a diffraction limited AO performance.

Factors influencing quality of patient interaction at community pharmacy drive-through and walk-in counselling areas.

2014-08-01

To examine factors influencing the amount of time and information pharmacy personnel provide to patients at drive-through and walk-in counselling areas. On-site observational data collection in 22 community pharmacies by pharmacy students. Information included observable patient characteristics such as gender, age range, English proficiency and mobility impairment; encounter characteristics included type of prescription and whether the patient was acknowledged; and counselling characteristics included types of counselling information conveyed and length of time for each encounter. Patient-pharmacist encounters were documented at the drive-through and walk-in counselling areas 961 and 1098 times respectively. Pharmacists spent less time, and technicians more time, with patients at the drive-through counselling area. The amount of information provided to patients was significantly affected by whether the patient was receiving new versus refill prescriptions. Patients with a new prescription were twice as likely to receive more information from pharmacy personnel. There was a significant difference between the amount of counselling provided to patients at the drive-through and walk-in counselling area (rate ratio (RR) 0.92, 95% confidence interval (CI): 0.86-1.00). Patients at the drive-through received a lower amount of information relative to patients using the walk-in. Amount of information provided to patients was affected by the level of pharmacy busyness (RR 0.96, 95% CI: 0.95-0.99). Providing patient care at the drive-through counselling area may negatively influence quality of patient care. To improve quality of pharmacy drive-through services, standardization of drive-through services in pharmacies may be needed. © 2013 Royal Pharmaceutical Society.

A recent cluster-randomized controlled trial found that offering financial incentives improves adherence to long-acting injectable antipsychotics (LAIs). The present study investigates whether the impact of incentives diminishes over time and whether the improvement in adherence is linked to the amount of incentives offered. Seventy-three teams with 141 patients with psychotic disorders (using ICD-10) were randomized to the intervention or control group. Over 1 year, patients in the intervention group received £15 (US $23) for each LAI, while control patients received treatment as usual. Adherence levels, ie, the percentage of prescribed LAIs that were received, were calculated for quarterly intervals. The amount of incentives offered was calculated from the treatment cycle at baseline. Multilevel models were used to examine the time course of the effect of incentives and the effect of the amount of incentives offered on adherence. Adherence increased in both the intervention and the control group over time by an average of 4.2% per quarterly interval (95% CI, 2.8%-5.6%; P < .001). Despite this general increase, adherence in the intervention group remained improved compared to the control group by between 11% and 14% per quarterly interval. There was no interaction effect between time and treatment group. Further, a higher total amount of incentives was associated with poorer adherence (βbootstrapped = -0.11; 95% CIbootstrapped, -0.20 to -0.01; P = .023). A substantial effect of financial incentives on adherence to LAIs occurs within the first 3 months of the intervention and is sustained over 1 year. A higher total amount of incentives does not increase the effect. ISRCTN.com identifier: ISRCTN77769281 and UKCRN.org identifier: 7033. © Copyright 2015 Physicians Postgraduate Press, Inc.

High-speed switching of biphoton delays through electro-optic pump frequency modulation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Odele, Ogaga D.; Lukens, Joseph M.; Jaramillo-Villegas, Jose A.

The realization of high-speed tunable delay control has received significant attention in the scene of classical photonics. In quantum optics, however, such rapid delay control systems for entangled photons have remained undeveloped. Here for the first time, we demonstrate rapid (2.5 MHz) modulation of signal-idler arrival times through electro-optic pump frequency modulation. Our technique applies the quantum phenomenon of nonlocal dispersion cancellation along with pump frequency tuning to control the relative delay between photon pairs. Chirped fiber Bragg gratings are employed to provide large amounts of dispersion which result in biphoton delays exceeding 30 ns. This rapid delay modulation schememore » could be useful for on-demand single-photon distribution in addition to quantum versions of pulse position modulation.« less

Anticholinergic toxicity in a one-year-old male following ingestion of Lupinus mutabilis seeds: case report.

PubMed

Flores-Pamo, Adrian Ernesto; Pisano, Elinor; Carreazo, Nilton Yhuri

2017-11-06

The seeds from Lupinus mutabilis Sweet, also called "chocho", are an important part of the diet in several countries in South America. Prior to consumption, processing is required to remove toxic alkaloids. These alkaloids are known to have pharmacological properties as antiarrhythmics, antimuscarinics and hypoglycemics. We report a case in which a one-year-old male initially presented with altered mental status and respiratory distress and subsequently developed symptoms of anticholinergic toxicity, after ingesting a large amount of chocho seeds. In spite of going through a difficult clinical condition, the subject evolved favorably through receiving supportive treatment. The seeds from Lupinus mutabilis provide nutritional benefits when consumed, but people need to know their risks when these seeds are consumed without proper preparation.

Design of an interventional magnetic resonance imaging coil for cerebral surgery

NASA Astrophysics Data System (ADS)

Xu, Yue; Wang, Wen-Tao; Wang, Wei-Min

2012-11-01

In clinical magnetic resonance imaging (MRI), the design of the radiofrequency (RF) coil is very important. For certain applications, the appropriate coil can produce an improved image quality. However, it is difficult to achieve a uniform B1 field and a high signal-to-noise ratio (SNR) simultaneously. In this article, we design an interventional transmitter-and-receiver RF coil for cerebral surgery. This coil adopts a disassembly structure that can be assembled and disassembled repeatedly on the cerebral surgery gantry to reduce the amount of interference from the MRI during surgery. The simulation results and the imaging experiments demonstrate that this coil can produce a uniform RF field, a high SNR, and a large imaging range to meet the requirements of the cerebral surgery.

2015-01-01

To analyze the effect of delayed hemorrhage after endoscopic sphincterotomy (EST) and compare the efficacy in improving complication between medicine treatment alone and medicine combined with endoscopic treatment. 1741 patients with EST admitted in Yijishan hospital of Wannan medical college from September 2009 to May 2014 were enrolled in this study. 32 cases suffered from delayed hemorrhage. The patients with delayed hemorrhage were evaluated through incision length of duodenal papilla, clinical manifestation, stool occult blood test and the difference of hemoglobin concentration between pre and post operation. 32 patients were divided into mild bleeding group, mild serious group and serious group through the speed and amount of bleeding. All cases in mild group accepted medicine treatment. Mild serious group were divided into medicine therapy group and medicine combined with endoscopic therapy group randomly. Serious group accepted vascular intervention therapy even traditional operation. The different treatments for delayed hemorrhage were judged by efficiency. The dates were analyzed by t-test or chi-square test. Nobody endured delayed hemorrhage who accepted small incision. Delayed hemorrhage was found in 7 patients out of 627 cases who accepted medium-large incision, 25 patients of 920 cases who accepted large incision. The patients who accepted lager EST were more dangerous than small EST (χ2=4.718, P=0.030) concerning delayed hemorrhage. 32 cases in 1741 patients suffered from delayed hemorrhage. 14 patients only have passed black stool after EST. Among 14 cases, 13 patients stop bleeding after medical therapy, and 1 case received endoscopic hemostasis. 15 cases with hematemesis or melena after EST, 7 patients who received combination therapy stop bleeding. 3 patients from 8 cases stop bleeding after single chemical treatment, 5 cases had to receive endoscopic hemostasis after ineffectual medical therapy. There are significant difference for concerning effect between combination therapy group and medical therapy group (P=0.026). 3 patients repeatedly vomited blood and develop to peripheral circulatory failure. Those patients all received vascular intervention therapy, 2 patients stop bleeding, 1 patient failed in vascular intervention therapy and given up emergency rescue and died. Large EST has more risks than small EST in concerning delayed hemorrhage. Delayed bleeding after EST should be treated by different levels. Adapted therapy should be recommend for patients with different levels bleeding. PMID:26131161

Beef customer satisfaction: USDA quality grade and marination effects on consumer evaluations of top round steaks.

2005-03-01

An in-home beef study evaluated consumer ratings of top round steaks (semimembranosus) as influenced by USDA quality grade (top Choice or high Select), city (Chicago or Philadelphia), consumer segment (beef loyalists = heavy consumers of beef; budget rotators = cost-driven and split meat consumption between beef and chicken; and variety rotators = higher incomes and education and split meat consumption among beef, poultry, and other foods), degree of doneness, cooking method, and marination. Consumers evaluated each steak for overall like, tenderness, juiciness, flavor like, and flavor amount using 10-point scales (1 = dislike extremely, not at all tender, not at all juicy, dislike extremely, and none at all to 10 = like extremely, extremely tender, extremely juicy, like extremely, and an extreme amount of flavor, respectively). Quality grade affected several consumer sensory traits, with top Choice receiving higher (P < or = 0.004) tenderness, juiciness, and flavor like scores than high Select. Consumers in Chicago rated steaks cooked "medium and less" higher for overall like, tenderness, juiciness, flavor like, and flavor amount than those in Philadelphia (city x degree of doneness; P < or = 0.020). Steaks braised by customers in Philadelphia received among the highest scores for overall like, tenderness, juiciness, flavor like, and flavor amount compared with any cooking method used by customers in Chicago (cooking method x city; P < or = 0.026). Overall like and flavor amount ratings were least (P < 0.05) for steaks that were marinated and cooked to "medium and less" degree of doneness (marination x degree of doneness; P < or = 0.014). Braised steaks received among the highest values for overall like, tenderness, juiciness, flavor like, and flavor amount when cooked to "medium and less" or "medium well and more" (cooking method x degree of doneness; P < or = 0.008). Correlation and stepwise regression analysis indicated that flavor like was pivotal in customers' satisfaction with top round steaks, and was the sensory trait most highly correlated to overall like, followed by tenderness, flavor amount, and juiciness. Preparation of top round steaks was crucial in consumers' likes and dislikes, and by improving flavor, higher consumer satisfaction may be achieved.

Occurrence and sources of Escherichia coli in metropolitan St. Louis streams, October 2004 through September 2007

USGS Publications Warehouse

Wilkison, Donald H.; Davis, Jerri V.

2010-01-01

The occurrence and sources of Escherichia coli (E. coli), one of several fecal indicator bacteria, in metropolitan St. Louis streams known to receive nonpoint source runoff, occasional discharges from combined and sanitary sewers, and treated wastewater effluent were investigated from October 2004 through September 2007. Three Missouri River sites, five Mississippi River sites, and six small basin tributary stream sites were sampled during base flow and storm events for the presence of E. coli and their sources. E. coli host-source determinations were conducted using local library based genotypic methods. Human fecal contamination in stream samples was additionally confirmed by the presence of Bacteroides thetaiotaomicron, an anaerobic, enteric bacterium with a high occurrence in, and specificity to, humans. Missouri River E. coli densities and loads during base flow were approximately 10 times greater than those in the Mississippi River above its confluence with the Missouri River. Although substantial amounts of E. coli originated from within the study area during base flow and storm events, considerable amounts of E. coli in the Missouri River, as well as in the middle Mississippi River sections downstream from its confluence with the Missouri River, originated in Missouri River reaches upstream from the study area. In lower Mississippi River reaches, bacteria contributions from the numerous combined and sanitary sewer overflows within the study area, as well as contributions from nonpoint source runoff, greatly increased instream E. coli densities. Although other urban factors cannot be discounted, average E. coli densities in streams were strongly correlated with the number of upstream combined and sanitary sewer overflow points, and the percentage of upstream impervious cover. Small basin sites with the greatest number of combined and sanitary sewer overflows (Maline Creek and the River des Peres) had larger E. coli densities, larger loads, and a greater percentage of E. coli attributable to humans than other small basin sites; however, even though small basin E. coli densities typically were much larger than in large river receiving streams, small basins contributed, on average, only a small part (a maximum of 16 percent) of the total E. coli load to larger rivers. On average, approximately one-third of E. coli in metropolitan St. Louis streams was identified as originating from humans. Another one-third of the E. coli was determined to have originated from unidentified sources; dogs and geese contributed lesser amounts, 10 and 20 percent, of the total instream bacteria. Sources of E. coli were largely independent of hydrologic conditions-an indication that sources remained relatively consistent with time.

Breaking the circle: challenging Western sociocultural norms for appearance influences young women's attention to appearance-related media.

2013-06-01

Paying attention to thin media models may negatively affect women's self-evaluation. This study aimed to reduce the amount of attention that young women give to appearance-related information by challenging the sociocultural norms for appearance, and studied the moderating role of self-esteem. Seventy-one college women either received norm-confirming, norm-challenging, or no information regarding the sociocultural norms for appearance. Subsequently, participants' visual attention to appearance-related and neutral advertisements was measured using an eye-tracker. The results demonstrate that when no information or norm-confirming information was received, women with lower self-esteem paid more attention to the appearance-related advertisements than women with higher self-esteem. Importantly however, when norm-challenging information was received, women with lower self-esteem paid significantly less attention to the appearance-related ads than women with lower self-esteem who did not receive this manipulation. These findings indicate that challenging the sociocultural norms for appearance can attenuate the amount of attention women give to appearance-related media. Copyright © 2013 Elsevier Ltd.

Predator size and the suitability of a common prey.

PubMed

Erickson, Kristin S; Morse, D H

1997-02-01

 Although a predator's mass should influence the suitability of its prey, this subject has received little direct attention. We studied the capture and processing of an abundant syrphid fly Toxomerus marginatus (c. 4 mg) by 0.6- to 40-mg juvenile crab spiders Misumena vatia (Thomisidae) to determine how profitability, relative profitability (profitability/predator mass), overall gain in mass, and relative gain in mass differed with predator mass, and whether foraging changed concurrently. In multi-prey experiments, the smallest successful spiders (0.6-3.0 mg) extracted less mass from flies, and did so more slowly, than large spiders. This gain was proportionately similar to that of 10- to 40-mg spiders with access to many Toxomerus. However, many small spiders failed to capture flies. When we gave spiders only a single Toxomerus, the smallest ones again extracted mass more slowly than the large ones and increased in mass less than the large ones, but increased in mass proportionately more than large ones. Relative gain in mass from a single prey decreased with increasing spider mass. Spiders larger than 10 mg all extracted similar amounts of mass from a single Toxomerus at similar rates, but varied in time spent between captures. Thus, Toxomerus changes with spider mass from a large, hard-to-capture bonanza to a small, easy-to-capture item of low per capita value. However, Toxomerus is common enough that large spiders can capture it en masse, thereby compensating for its decline in per capita value.

Review of medical findings in a Marshallese population twenty-six years after accidental exposure to radioactive fallout

DOE Office of Scientific and Technical Information (OSTI.GOV)

Conard, R.A.; Paglia, D.E.; Larsen, P.R.

1980-01-01

In March 1954, radioactive debris from a thermonuclear weapon test at Bikini Atoll deviated from predicted trajectories and contaminated several atolls in the northern Marshall Islands. As a result, 239 native inhabitants of these islands along with 28 American servicemen and 23 Japanese fishermen received variably severe exposures to diverse ionizing radiations. Fallout material consisted largely of mixed fission products with small amounts of neutron-induced radionuclides and minimal amounts of fissionable elements, producing a complex spectrum of electromagnetic and particulate radiation. Individuals were exposed to deeply penetrating, whole-body gamma irradiation, to internal radiation emitters assimilated either by inhalation or bymore » ingestion of contaminated water and food, and to direct radiation from material accumulating on body surfaces. That accident initiated a cascade of events, medical, social and political, which continue in varying forms to this day. Most of these have been discussed in the open medical literature and in periodic reports issued by the medical team headquartered at Brookhaven National Laboratory. This report attempts to summarize some of the principal findings of medical significnce that have been observed during the subsequent 26 years with particular emphasis on the last six years.« less

Preparing for the Next Generation of Direct Broadcast

With the anticipated launch of NPP, JPSS-1 and GOES-R in the next five years, the flow of weather data to users will rise ten times (Berchoff, 2009). This volume of data will put a strain on the government infrastructure tasked for data distribution, which could limit real-time data distribution to government users only, forcing others to retrieve their data days to weeks later. In order to receive real-time data, direct reception will become a necessity. SeaSpace Corporation has created a complete solution in anticipation of the forthcoming needs of data users. This solution is made up of four parts: 1) ground reception stations, 2) software to process the data into products, 3) data storage hardware, and 4) data cataloging software and server. The ground station component consists of two systems, an X/L/S-band tracking system and an L-band geostationary system. The combined X-, L-, and S-band reception capabilities are included to ensure the user can receive the maximum amount of data. The X-band receiver in this system can receive data from Terra, Aqua, NPP, JPSS, Oceansat-2, and FY-3. The L-band receiver can currently receive NOAA and MetOp. The follow-on to MetOp will be assigned the mid-morning orbit in the next generation constellation, ensuring L-band reception will continue to be a necessity. The S-band is used for DMSP reception, which may, in the near-future, become more widely available to non-defense clients. The L-band stationary antenna in the proposed solution is used for reception of geostationary satellites, such as GOES, COMS, and MTSAT. Upon launch, GOES-R data can be received with hardware/software upgrade. Once the data is received by the ground stations, TeraScan’s Rapid Environmental Processing System (REPS) automatically processes the data through level 3 products using the official NOAA and NASA algorithms. REPS can process large amounts of satellite data incredibly quickly: for instance, all MODIS products are produced in less than fifteen minutes. After processing, the raw data and products are moved to TeraVault™, SeaSpace’s data storage solution. TeraVault™ comes standard with 84 TB of storage, can be easily expanded, and allows online and readily accessible storage for data. In order to easily manage data of this volume, SeaSpace recommends the TeraCat™ data catalog and retrieval system, which gives users and their customers a web-based interface to search for and order their data. A full direct-reception solution is the only way to guarantee real-time access to the next generation of environmental satellite data. The currently over-tasked system of data distribution via the internet is ill-equipped to service local and foreign customers on a real-time basis now, and this will only get worse as more data comes online.

We use Moho depth variations extracted from receiver function analyses to predict synthetic Bouguer anomalies that are then compared to observed Bouguer anomaly. We find that Moho depth variations due to isostatic compensation of topographic and/or intracrustal loads do not match Moho depth estimates obtained from receiver function analyses. The isostatic misfit map evidences excess crustal root as large as 10 km in the western part of the study area, whereas a `missing' crustal root of ˜5 km appears east of 4.3°E. This excess root/missing topography correlates with the presence of a dense mantle lid, the noticeable southwestward drift of the Western Rif area, and with a current surface uplift. We propose that a delaminated mantle lid progressively detaching westward or southwestward from the overlying crust is responsible for viscous flow of the ductile lower crust beneath the Rif area. This gives rise to isostatic uplift and westward drift due to viscous coupling at the upper/lower crust boundary. At the same time, the presence of this dense sinking mantle lid causes a negative dynamic topography, which explains why the observed topography is too low compared to the crustal thickness.

Synchronized SETI-The Case for "Opposition"

NASA Astrophysics Data System (ADS)

Corbet, Robin H. D.

2003-06-01

If the signals being sought in search for extraterrestrial intelligence (SETI) programs exist but are brief (for example, they are produced intermittently to conserve energy), then it is essential to know when these signals will arrive at the Earth. Different types of transmitter/receiver synchronization schemes are possible, which vary in the relative amount of effort required by the transmitter and the receiver. The case is made for a scheme that is extremely simple for the receiver: Make observations of a target when it is at maximum angular distance from the Sun (i.e., "opposition"). This strategy requires that the transmitter has accurate knowledge of the distance and proper motion of the Sun and the orbit of the Earth. It is anticipated that within the next 10-20 years it will be possible to detect directly nearby extrasolar planets of approximately terrestrial mass. Since extraterrestrial transmitters are expected to have significantly more advanced technology, it is not unreasonable to expect that they would be able to detect the presence of the Earth and measure its orbit at even greater distances. This strategy is simple to implement, and opposition is also typically the time when observations are easiest to make. Limited opposition surveys contained in a number of all-sky surveys have already been performed. However, full-sky opposition surveys are best suited to detectors with very large fields of view.

In biosand filters (BSF), treatment is largely driven by the development of a biolayer (schmutzdecke) which establishes itself during the startup phase. In the present study, the effect of changing influent total organic carbon (TOC) loading on the removal efficiency of Vibrio cholerae in laboratory-operated BSFs was quantified. BSFs were charged with high, medium or low TOC influents and removal efficacy and schmutzdecke composition was monitored over two months. The highest V. cholerae removal efficiencies were observed in the BSF receiving the lowest TOC. Schmutzdecke composition was found to be influenced by influent TOC, in terms of microbial community structure and amount of extracellular polymeric substance (EPS). Physical/chemical attachment was shown to be important during startup. The BSF receiving influent water with lower TOC had a higher attachment coefficient than the BSF receiving high TOC water, suggesting more physical/chemical treatment in the lower TOC BSF. The high TOC BSF had more EPS than did the biofilm from the low TOC BSF, suggesting that schmutzdecke effects may be more significant at high TOC. Overall, this study confirms that influent water characteristics will affect BSF treatment efficacy of V. cholerae especially during the startup phase. This article is protected by copyright.

University of TX Bureau of Economic Geology's Core Research Centers: The Time is Right for Registering Physical Samples and Assigning IGSN's - Workflows, Stumbling Blocks, and Successes.

2016-12-01

The University Of Texas Bureau Of Economic Geology (BEG) serves as the geological survey for Texas and operates three geological sample repositories that house well over 2 million boxes of geological samples (cores and cuttings) and an abundant amount of geoscience data (geophysical logs, thin sections, geochemical analyses, etc.). Material is accessible and searchable online, and it is publically available to the geological community for research and education. Patrons access information about our collection by using our online core and log database (SQL format). BEG is currently undertaking a large project to: 1) improve the internal accuracy of metadata associated with the collection; 2) enhance the capabilities of the database for both BEG curators and researchers as well as our external patrons; and 3) ensure easy and efficient navigation for patrons through our online portal. As BEG undertakes this project, BEG is in the early stages of planning to export the metadata for its collection into SESAR (System for Earth Sample Registration) and have IGSN's (International GeoSample Numbers) assigned to its samples. Education regarding the value of IGSN's and an external registry (SESAR) has been crucial to receiving management support for the project because the concept and potential benefits of registering samples in a registry outside of the institution were not well-known prior to this project. Potential benefits such as increases in discoverability, repository recognition in publications, and interoperability were presented. The project was well-received by management, and BEG fully supports the effort to register our physical samples with SESAR. Since BEG is only in the initial phase of this project, any stumbling blocks, workflow issues, successes/failures, etc. can only be predicted at this point, but by mid-December, BEG expects to have several concrete issues to present in the session. Currently, our most pressing issue involves establishing the most efficient workflow for exporting of large amounts of metadata in a format that SESAR can easily ingest, and how this can be best accomplished with very few BEG staff assigned to the project.

Child support and alimony: 1981.

This report presents information (including 13 tables) as of spring 1982 on payments made to mothers for child support by fathers not living in the same household, and information on support payments and property settlement awards for women involved in marital dissolution. As of spring 1982, 8.4 million mothers were living with a child under 21 years of age whose father was not living with them; 59% of these women were or would be awarded child support payments than black women (34%) or those of Spanish origin (44%). College educated women were more likely to be awarded and to receive child support payments than women with only a high school education. The average amount of child support received in 1981 was $2,110, a decrease of about 16% from the 1978 level of $2,510. Of the 2.6 million women below the poverty level with children present from an absent father, about 40% received child support. Among the poor, 806,000 women were due child support in 1981 but only 61% received some amount of payment. As of spring 1982, only about 15% of the 17 million divorced or separated women received alimony. In 1981 alimony averaged $3,000, a 25% decrease from the 1978 level of $3,980. In spring 1982, about 42% of the 14.2 million divorced women reported receiving some form of property settlement.

The Hanford Environmental Dose Reconstruction (HEDR) Project was established to estimate radiation doses that people could have received from nuclear operations at the Hanford Site since 1944. For this period iodine-131 is the most important offsite contributor to radiation doses from Hanford operations. Consumption of milk from cows that ate vegetation contaminated by iodine-131 is the dominant radiation pathway for individuals who drank milk. Information has been developed on commercial milk cow locations and commercial milk distribution during 1945 and 1951. The year 1945 was selected because during 1945 the largest amount of iodine-131 was released from Hanford facilities inmore » a calendar year; therefore, 1945 was the year in which an individual was likely to have received the highest dose. The year 1951 was selected to provide data for comparing the changes that occurred in commercial milk flows (i.e., sources, processing locations, and market areas) between World War II and the post-war period. To estimate the doses people could have received from this milk flow, it is necessary to estimate the amount of milk people consumed, the source of the milk, the specific feeding regime used for milk cows, and the amount of iodine-131 contamination deposited on feed.« less

2015-10-01

The effects of race-ethnicity on the use of paid and unpaid caregivers for those with spinal cord injury (SCI) have received little attention in the literature. Compare the amount of paid and unpaid caregiver hours received and sources of caregiving between non-Hispanic White and non-Hispanic Black participants with SCI, controlling for demographic, injury-related, and economic variables. Participants were identified from a large specialty hospital. Self-report data were collected by mail. Five aspects of caregiving were assessed: (a) paid assistance hours, (b) satisfaction with care, (c) unpaid assistance hours, (d) sources of informal care, and (e) evaluation of whether needs were met. Whites were more satisfied with paid care. Approximately 43.4% of Whites received informal care from their spouse every day, 14.7% higher than Blacks. Blacks were more likely to receive informal care from other family members, friends, church, and others. When controlling for gender, injury severity, chronological age, and years post injury, Blacks reported 1.50 more paid assistance hours (95% CI, 0.31-2.68 hours) and 1.83 less unpaid assistance hours than Whites (95% CI, 0.25-3.41 hours). Differences diminished and were not statistically significant after adding marital status and income into regression models. The results did not provide strong evidence of racial disparities regarding caregiver assistance for those with SCI. Level of income appears to be directly related to satisfaction of quality caregiving and the use of paid versus unpaid care for those living with SCI. Copyright © 2015 Elsevier Inc.

Assessment of Heavy Metal Pollution in Sediments of Inflow Rivers to Lake Taihu, China.

PubMed

Niu, Yong; Niu, Yuan; Pang, Yong; Yu, Hui

2015-11-01

Lake Taihu, the third-largest freshwater body in China, has many functions, including drinking water supply, flood control, cultivation, navigation, and tourism. In this study, sediment samples were collected at 31 sites from 11 inflow rivers in 2012, to investigate the distribution and concentration of heavy metals copper (Cu), zinc (Zn), lead (Pb), nickel (Ni), and chromium (Cr), and to assess their potential ecological risk. The highest mean concentration was found for Zn, followed by Cu, Cr, Pb, and Ni. Generally, heavy metal pollution was more serious in Wu Jingang River and Caoqiao River, probably because they receive large amounts of wastewater from various local industrial enterprises. The potential ecological risk values of the heavy metals were larger than 120 in more than 25.8% of the sediment samples, indicating a very high risk. The largest ecological risk was due to copper. Furthermore, the results of a principal component analysis and subsequent analysis of variance showed that heavy metal concentrations in the sediment of inflow rivers were higher than those of the lake, which created a large hazard for the aquatic ecosystems of Lake Taihu.

Optimizing support vector machine learning for semi-arid vegetation mapping by using clustering analysis

NASA Astrophysics Data System (ADS)

Su, Lihong

In remote sensing communities, support vector machine (SVM) learning has recently received increasing attention. SVM learning usually requires large memory and enormous amounts of computation time on large training sets. According to SVM algorithms, the SVM classification decision function is fully determined by support vectors, which compose a subset of the training sets. In this regard, a solution to optimize SVM learning is to efficiently reduce training sets. In this paper, a data reduction method based on agglomerative hierarchical clustering is proposed to obtain smaller training sets for SVM learning. Using a multiple angle remote sensing dataset of a semi-arid region, the effectiveness of the proposed method is evaluated by classification experiments with a series of reduced training sets. The experiments show that there is no loss of SVM accuracy when the original training set is reduced to 34% using the proposed approach. Maximum likelihood classification (MLC) also is applied on the reduced training sets. The results show that MLC can also maintain the classification accuracy. This implies that the most informative data instances can be retained by this approach.

Ultrafast entanglement of trapped ions

NASA Astrophysics Data System (ADS)

Neyenhuis, Brian; Mizrahi, Jonathan; Johnson, Kale; Monroe, Christopher

2013-05-01

We have demonstrated ultrafast spin-motion entanglement of a single atomic ion using a short train of intense laser pulses. This pulse train gives the ion a spin-dependent kick where each spin state receives a discrete momentum kick in opposite directions. Using a series of these spin-dependent kicks we can realize a two qubit gate. In contrast to gates using spectroscopically resolved motional sidebands, these gates may be performed faster than the trap oscillation period, making them potentially less sensitive to noise, independent of temperature, and more easily scalable to large crystals of ions. We show that multiple kicks can be strung together to create a ``Schrodinger cat'' like state, where the large separation between the two parts of the wavepacket allow us to accumulate the phase shift necessary for a gate in a shorter amount of time. We will present a realistic pulse scheme for a two ion gate, and our progress towards its realization. This work is supported by grants from the U.S. Army Research Office with funding from the DARPA OLE program, IARPA, and the MURI program; and the NSF Physics Frontier Center at JQI.

Water Ecosystem Services in Northern Australia—How Much Are They Worth and Who Should Pay for Their Provision?

PubMed Central

Zander, Kerstin K.; Parkes, Rowena; Straton, Anna; Garnett, Stephen T.

2013-01-01

There is ongoing pressure to develop the largely unaltered Daly River catchment in northern Australia for agriculture. However, a choice experiment among people in the region and in Australia’s largest city, Sydney, shows that people are prepared to pay substantial amounts to maintain the quality of its ecosystem services. The total stated willingness-to-pay (WTP) for a Daly River conservation programme was about $300, of which people would be willing to pay over half ($161) if the programme retained waterholes for Aboriginal people in good condition. The WTP for high quality recreational fishing and biodiversity values was $120 and $91 respectively. Using the average cost of a recreational fishing license in Australia ($35) as a basis for grounding the stated preferences in empirical values, as well as the cost of park entry fees and the amount of support society provides to agriculture in Australia, the total amount that the 110,000 people in the region are likely to be willing to pay for the retention of the values in the Daly River catchment is about $6 million, while the 4.5 million people in Sydney would be willing to pay about $81 million. A significant finding in this research is that, while fishing, biodiversity and agricultural values all have equivalents in the market economy, the value for which people were willing to pay most, the cultural value, has no equivalent at all and is thus receives almost no investment.

Residual Effects of Fertilization History Increase Nitrous Oxide Emissions from Zero-N Controls: Implications for Estimating Fertilizer-Induced Emission Factors.

PubMed

LaHue, Gabriel T; van Kessel, Chris; Linquist, Bruce A; Adviento-Borbe, Maria Arlene; Fonte, Steven J

2016-09-01

Agricultural N fertilization is the dominant driver of increasing atmospheric nitrous oxide (NO) concentrations over the past half-century, yet there is considerable uncertainty in estimates of NO emissions from agriculture. Such estimates are typically based on the amount of N applied and a fertilizer-induced emission factor (EF), which is calculated as the difference in emissions between a fertilized plot and a zero-N control plot divided by the amount of N applied. A fertilizer-induced EF of 1% is currently recognized by the Intergovernmental Panel on Climate Change (IPCC) based on several studies analyzing published field measurements of NO emissions. Although many zero-N control plots used in these measurements received historical N applications, the potential for a residual impact of these inputs on NO emissions has been largely ignored and remains poorly understood. To address this issue, we compared NO emissions under laboratory conditions from soils sampled within zero-N control plots that had historically received N inputs versus soils from plots that had no N inputs for 20 yr. Historical N fertilization of zero-N control plots increased initial NO emissions by roughly one order of magnitude on average relative to historically unfertilized control plots. Higher NO emissions were positively correlated with extractable N and potentially mineralizable N. This finding suggests that accounting for fertilization history may help reduce the uncertainty associated with the IPCC fertilizer-induced EF and more accurately estimate the contribution of fertilizer N to agricultural NO emissions, although further research to demonstrate this relationship in the field is needed.

Potassium Inhibits Dietary Salt-Induced Transforming Growth Factor-β Production

PubMed Central

Ying, Wei-Zhong; Aaron, Kristal; Wang, Pei-Xuan; Sanders, Paul W.

2009-01-01

Human and animal studies demonstrate an untoward effect of excess dietary NaCl (salt) intake on cardiovascular function and life span. The endothelium in particular augments the production of transforming growth factor (TGF)-β, a fibrogenic growth factor, in response to excess dietary salt intake. This study explored the initiating mechanism that regulates salt-induced endothelial cell production of TGF-β. Male Sprague-Dawley rats were given diets containing different amounts of NaCl and potassium for 4 days. A bioassay for TGF-β demonstrated increased (35.2%) amounts of active TGF-β in the medium of aortic ring segments from rats on the high-salt diet compared with rats maintained on a 0.3% NaCl diet. Inhibition of the large-conductance, calcium-activated potassium channel inhibited dietary salt-induced vascular production of TGF-β but did not affect production of TGF-β by ring segments from rats on the low-salt diet. Immunohistochemical and Western analyses demonstrated the α subunit of the calcium-activated potassium channel in endothelial cells. Increasing medium [K+] inhibited production of dietary salt-induced vascular production levels of total and active TGF-β but did not alter TGF-β production by aortic rings from rats on the 0.3% NaCl diet. Increasing dietary potassium content decreased urinary active TGF-β in animals receiving the high-salt diet but did not change urinary active TGF-β in animals receiving the low-salt diet. The findings demonstrated an interesting interaction between the dietary intake of potassium and excess NaCl and further showed the fundamental role of the endothelial calcium-activated potassium channel in the vascular response to excess salt intake.

Urban heat island effect commonly refers to temperature differences between urban areas and their countrysides due to urbanization. These temperature differences are evident at surface, and within the canopy and the boundary layer. This effect is heterogeneous within the city, and responds to urban morphology, prevailing materials, amount of vegetation, among others, which are also important in the urban balance of energy. In order to study the relationship between land surface temperature (LST) and urban coverage over Aburrá Valley, which is a narrow valley locate at tropical Andes in northern South America, Landsat 8 mission products of LST, density of vegetation (normalized difference vegetation index, NDVI), and a proxy of soil humidity are derived and used. The results are analyzed from the point of view of dominant urban form and settlement density at scale of neighborhoods, and also from potential downward solar radiation received at the surface. Besides, specific sites were chosen to obtain LST from thermal imaging using an unmanned aerial vehicle to characterize micro-scale patterns and to validate Landast retrievals. Direct relationships between LST, NDVI, soil humidity, and duration of insolation are found, showing the impact of the current spatial distribution of land uses on surface temperature over Aburrá Valley. In general, the highest temperatures correspond to neighborhoods with large, flat-topped buildings in commercial and industrial areas, and low-rise building in residential areas with scarce vegetation, all on the valley bottom. Landsat images are in the morning for the Aburrá Valley, for that reason the coldest temperatures are prevalent at certain orientation of the hillslope, according with the amount of radiation received from sunrise to time of data.

Nonhuman primate species spend a conspicuous amount of time grooming during social interactions, a behavior that probably serves both social and health-related functions. While the social implications of grooming have been relatively well studied, less attention has been paid to the health benefits, especially the removal of ectoparasites, which may act as vectors in disease transmission. In this study, we examined the relationship between grooming behavior, tick load (number of ticks), and haemoprotozoan infection status in a population of wild free-ranging baboons (Papio cynocephalus). We found that the amount of grooming received was influenced by an individual’s age, sex and dominance rank. The amount of grooming received, in turn, affected the tick load of an individual. Baboons with higher tick loads had lower packed red cell volume (PCV or haematocrit), one general measure of health status. We detected a tick-borne haemoprotozoan, Babesia microti, but its low prevalence in the population precluded identifying sources of variance in infection. PMID:24659824

Background A number of studies have shown that bite and sip sizes influence the amount of food intake. Consuming with small sips instead of large sips means relatively more sips for the same amount of food to be consumed; people may believe that intake is higher which leads to faster satiation. This effect may be disturbed when people are distracted. Objective The objective of the study is to assess the effects of sip size in a focused state and a distracted state on ad libitum intake and on the estimated amount consumed. Design In this 3×2 cross-over design, 53 healthy subjects consumed ad libitum soup with small sips (5 g, 60 g/min), large sips (15 g, 60 g/min), and free sips (where sip size was determined by subjects themselves), in both a distracted and focused state. Sips were administered via a pump. There were no visual cues toward consumption. Subjects then estimated how much they had consumed by filling soup in soup bowls. Results Intake in the small-sip condition was ∼30% lower than in both the large-sip and free-sip conditions (P<0.001). In addition, subjects underestimated how much they had consumed in the large-sip and free-sip conditions (P<0.03). Distraction led to a general increase in food intake (P = 0.003), independent of sip size. Distraction did not influence sip size or estimations. Conclusions Consumption with large sips led to higher food intake, as expected. Large sips, that were either fixed or chosen by subjects themselves led to underestimations of the amount consumed. This may be a risk factor for over-consumption. Reducing sip or bite sizes may successfully lower food intake, even in a distracted state. PMID:23372657

Low-temperature (77 K) steady-state fluorescence emission spectroscopy and dynamic light scattering were applied to the main chlorophyll a/b protein light harvesting complex of photosystem II (LHC II) in different aggregation states to elucidate the mechanism of fluorescence quenching within LHC II oligomers. Evidences presented that LHC II oligomers are heterogeneous and consist of large and small particles with different fluorescence yield. At intermediate detergent concentrations the mean size of the small particles is similar to that of trimers, while the size of large particles is comparable to that of aggregated trimers without added detergent. It is suggested that in small particles and trimers the emitter is monomeric chlorophyll, whereas in large aggregates there is also another emitter, which is a poorly fluorescing chlorophyll associate. A model, describing populations of antenna chlorophyll molecules in small and large aggregates in their ground and first singlet excited states, is considered. The model enables us to obtain the ratio of the singlet excited-state lifetimes in small and large particles, the relative amount of chlorophyll molecules in large particles, and the amount of quenchers as a function of the degree of aggregation. These dependencies reveal that the quenching of the chl a fluorescence upon aggregation is due to the formation of large aggregates and the increasing of the amount of chlorophyll molecules forming these aggregates. As a consequence, the amount of quenchers, located in large aggregates, is increased, and their singlet excited-state lifetimes steeply decrease.

Objective: To explore the safety and feasibility of associating diaphragm resection and liver-diaphragmatic metastasis lesions resection for patients with advanced ovarian cancer. Methods: Retrospectively analysis 83 cases(98 times) of advanced ovarian cancer with liver-diaphragmatic metastasis between January 2012 and December 2016 at Department of Liver Surgery, Peking Union Medical College Hospital.The patients were aged from 19 to 75 years.Surgical procedure included metastatic lesions resection(43 times) and stripping(55 times). Operation status, post-operative complications, pathology results and follow-up of the patients were analyzed. Results: Fifteen patients received twice surgical treatment and 68 patients received one time surgical treatment. Postoperative hemorrhage in chest and between liver and diaphragm was not occurred in all cases.Dyspnea and low oxygen saturation were occurred in two cases of stripping patients and 1 case of metastatic lesions resection patients.Results of CT examination indicated that there was medium to large amount of ascites in right chests.The symptoms were relieved after placing thoracic closed drainage.Other patients were recovered smoothly.All patients were diagnosed as ovarian cancer by pathological examination. Conclusion: Associating diaphragm resection is safe and feasible for liver-diaphragmatic metastasis lesions from ovarian cancer.

Excessive coffee drinking can have deleterious effects because of the large amounts of caffeine that are ingested. Caffeine is thought to be addicting, and prolonged and excessive use can lead to caffeinism, a condition that has serious behavioral and physiological side effects. The present study developed and evaluated a treatment program to reduce excessive daily coffee drinking to moderate and presumably safer levels. Three habitual coffee drinkers received individualized changing criterion programs that systematically and gradually reduced their daily caffeine intake. The coffee drinkers were required to self-monitor and plot their daily intake of caffeine. They received monetary prizes for not exceeding the treatment phase criteria and forfeited a portion of their pretreatment deposit when they did. Their coffee drinking decreased from almost nine cups per day (over 1100 mg of caffeine) during baseline to less than three cups per day (less than 343 mg) at the end of treatment or a reduction of 69%. The treatment effect was maintained during a 10-month follow-up, averaging a 67% reduction from baseline. The program appears to be a reasonable method of reducing and then maintaining daily caffeine intake at less harmful levels. PMID:511802

Since the eighties of the last century hormone content was justified in immune cells (lymphocytes, granulocytes, monocytes, macrophages and mast cells), which produce, store and secrete these hormones. Although the amount of these materials in immune cells is relatively small, the mass of the producers (immune cells) is so large, that the phenomenon must be considered from endocrinological point of view, underlying the important differences between the "classical" and immuno-endocrine systems. Cells of the classic (built-in) endocrine system are mono-producers, while immune cells can synthesize many types of hormones (polyproducers). In addition, these cells can transport the whole hormone-producing machinery to the site of need, producing a local effect. This can be observed, for example, in the case of endorphin producing immune cells during inflammation and during early pregnancy around the chorionic villi. Hormone producing immune cells also have receptors for many hormones, so that they are poly-receivers. Via hormone producing and receiving capacity there is a bidirectional connection between the neuro-endocrine and immuno-endocrine systems. In addition, there is a network inside the immuno-endocrine system. The packed transport theory attempts to explain the mechanism and importance of the immuno-endocrine system.

In the production of building materials produces a large amount of harmful substances, poisoning atmosphere and adjacent to the building materials site. One of the biggest polluting the ecology of cities adjacent to industry, is metallurgical industry. One of the most important technological processes is the enrichment, in which the rocks are extracted empty components. In the enrichment of iron ore in the production an increasing proportion consist the anthropogenic waste industries, which pollute the air basin and the huge territory around the factories that dumped these same wastes. This reduces as a space for human life and for the functioning and development of cities. These materials can be applied as construction materials, for example, in the preparation of fine-grained concrete as a mineral powder, and these materials can be applied in the construction of roads, housing, for receiving paint etc.

Effect of insecticides and phenolics on nitrogen fixation by Nostoc linckia

Megharaj, M.; Venkateswarlu, K.; Rao, A.S.

1988-08-01

The nitrogen-fixing blue-green algae (cyanobacteria) significantly influence the nitrogen economy of temperate and tropical soils. Although the genera Nostoc and Tolypothrix have been particularly implicated in the fixation of significantly large amounts of atmospheric nitrogen, these diazotrophs received little attention in relation to insecticide treatment and the available few reports do not indicate a permanent deleterious effect of insecticides on their nitrogenase activity. As it has been well established that the effect of insecticides on nitrogen fixation by cyanobacteria is independent of that on growth, an attempt was, therefore, made to determine the influence of four insecticides (monocrotophos, quinalphos, cypermethrinmore » and fenvalerate) and four phenolics (p-nitrophenol (PNP), m-nitrophenol (MNP), 2,4-dinitrophenol (DNP) and catechol) on nitrogen-fixing capacity of N.linckia, isolated from a black soil.« less

The issues of cheating and plagiarism in educational settings have received a large amount of attention in recent years. The purpose of this study was to assess the degree to which academic integrity issues currently exist in the dental schools throughout the United States and Canada. An online survey was developed to gather data pertaining to this topic from two key groups in dental education: faculty and students. Responses were obtained from 1,153 students and 423 faculty members. The results of the survey clearly reveal that cheating is a significant problem in dental schools and that significant differences exist between students' and faculty members' perceptions of academic integrity. The challenge for dental schools is to identify effective strategies to prevent cheating opportunities and to implement and enforce effective means of dealing with specific examples of cheating.

An increasing number of patients and families are utilizing online crowdfunding to support their medical expenses related to organ transplantation. The factors influencing the success of crowdfunding campaigns are poorly understood. Crowdfunding campaigns were abstracted from a popular crowdfunding web site. Campaigns were included if they were actively accepting donations to fund medical expenses related to transplantation of selected organs. The primary outcome measure was total amount raised among successful campaigns receiving at least one donation. Bivariate and multivariate analyses were performed on various campaign characteristics. A total of 850 campaigns were analyzed. Kidney transplant campaigns were most common (40.5%), followed by liver (33.3%), lung (12.2%), heart (11.3%), and multiorgan (2.7%). 69.1% of campaigns received any donation, and among these, the mean amount raised was $3664 (median $1175). The following factors were significantly associated with amount raised: more positive emotional sentiment in the campaign description (+2.6% per AFINN unit, P < .001), longer campaign description length (+2.4% per 100 characters, P = .001), higher goal amount (+0.6% per $1000 of goal amount, P = .004), and third-person description perspective (+131% vs first person, P < .001). Physicians will likely encounter medical crowdfunding with increasing frequency as it continues to grow in popularity among their patients. © 2018 John Wiley & Sons A/S.

A study of the amount of drug advertisements received by general practitioners and the amount of the drugs practitioners prescribed showed a strong correlation of 0·80. Analysis suggests that a straight line graphic relationship provides the best fit for the results obtained. Further analysis of the quantity of advertising in relation to the amount of prescribing revealed two groups of drugs: those which were relatively more and those which were relatively less often advertised in proportion to the number of prescriptions issued for them.

Although physiotherapy (PT) plays an important role in improving activities of daily living (ADL functioning) and discharge rates, it is unclear how many nursing home residents receive treatment. Furthermore, there is a lack of insight into the determinants that influence the decision for treatment. In this study, we investigated how many nursing home residents receive PT. In addition, we analysed the factors that contribute to the variation in the provision of PT both between nursing homes and between residents. A random sample of 600 elderly residents was taken from a random sample of 15 nursing homes. Residents had to be admitted for rehabilitation or for long-term care. Data were collected through interviews with the nursing home physician and the physiotherapist. Multilevel analysis was used to define the variation in the provision of PT and the factors that are associated with the question whether a resident receives PT or not. Furthermore the amount of PT provided was analysed and the factors that are associated with this. On average 69% of the residents received PT. The percentage of patients receiving treatment differed significantly across nursing homes, and especially the number of physiotherapists available, explained this difference between nursing homes. Residents admitted to a somatic ward for rehabilitation, and male residents in general, were most likely to receive PT. Residents who were treated by a physiotherapist received on average 55 minutes (sd 41) treatment a week. Residents admitted for rehabilitation received more PT a week, as were residents with a status after a total hip replacement. PT is most likely to be provided to residents on a somatic ward, recently admitted for rehabilitation to a nursing home, which has a relatively large number of physiotherapists. This suggests a potential under-use of PT for long-term residents with cognitive problems. It is recommended that physiotherapists reconsider which residents may benefit from treatment. This may require a shift in the focus of physiotherapists from 'recovery and discharge' to 'quality of life and well-being'.

Background and objectives Prior living donors (PLDs) receive very high priority on the Organ Procurement and Transplantation Network (OPTN) kidney waiting list. Program delays in adding PLDs to the waiting list, setting their status to active, and submitting requests for PLD priority can affect timely access to transplantation. Design, setting, participants, & measurements We used the OPTN and the Centers for Medicare and Medicaid Services data to examine timing of (1) listing relative to start of dialysis, (2) activation on the waiting list, and (3) requests for PLD priority relative to listing date. There were 210 PLDs (221 registrations) added to the OPTN kidney waiting list between January 1, 2010 and July 31, 2015. Results As of September 4, 2015, 167 of the 210 PLDs received deceased donor transplants, six received living donor transplants, two died, five were too sick to transplant, and 29 were still waiting. Median waiting time to deceased donor transplant for PLDs was 98 days. Only 40.7% of 221 PLD registrations (n=90) were listed before they began dialysis; 68.3% were in inactive status for <90 days, 17.6% were in inactive status for 90–365 days, 8.6% were in inactive status for 1–2 years, and 5.4% were in inactive status for >2 years. Median time of PLDs waiting in active status before receiving PLD priority was 2 days (range =0–1450); 67.4% of PLDs received PLD priority within 7 days after activation, but 15.4% waited 8–30 days, 8.1% waited 1–3 months, 4.1% waited 3–12 months, and 5.0% waited >1 year in active status for PLD priority. After receiving priority, most were transplanted quickly. Median time in active status with PLD priority before deceased donor transplant was 23 days. Conclusions Fewer than one half of listed PLDs were listed before starting dialysis. Most listed PLDs are immediately set to active status and receive PLD priority quickly, but a substantial number spends time in active status without PLD priority or a large amount of time in inactive status, which affects access to timely transplants.

The offshore export of sand during exceptional discharge from California rivers

USGS Publications Warehouse

Warrick, Jonathan A.; Barnard, Patrick L.

2012-01-01

Littoral cells along active tectonic margins receive large inputs of sand and gravel from coastal watersheds and commonly lose this sediment to submarine canyons. One hypothesis is that the majority of coarse (sand and gravel) river sediment discharge will be emplaced within and immediately “resupply” local littoral cells. A competing hypothesis is that the infrequent, large floods that supply the majority of littoral sediment may discharge water-sediment mixtures within negatively buoyant hyperpycnal plumes that transport sediment offshore of the littoral cell. Here we summarize pre- and post-flood surveys of two wave-dominated California (United States) river deltas during record to near-record floods to help evaluate these hypotheses: the 1982–1983 delta at the San Lorenzo River mouth and the 2005 delta at the Santa Clara River mouth. Flood sedimentation at both deltas resulted in several meters of aggradation and hundreds of meters of offshore displacement of isobaths. One substantial difference between these deltas was the thick (>2 m) aggradation of sand on the inner shelf of the Santa Clara River delta that contained substantial amounts (∼50%) of littoral-grade sediment. Once deposited on the inner shelf, only a fraction (∼20%) of this river sand was observed to migrate toward the beach over the following 5 yr. Furthermore, simple hypopycnal plume behavior could not explain deposition of this sand on the inner shelf. Thus, during an exceptional flood a substantial amount of littoral-grade sand was exported offshore of the littoral system at the Santa Clara River mouth—likely from hyperpycnal plume processes—and was deposited on the inner shelf.

To explore the clinical diagnostic features and treatment of desmoplastic small round cell tumor (DSRCT), and to improve the understanding and management of this tumor. The clinicopathological data of nine patients treated in our hospital from October 2004 to June 2014 were retrospectively analyzed and a review of the literature was made. The clinical manifestations, pathological characteristics, diagnosis and differential diagnosis, treatment and prognosis of this tumor were summarized and analyzed. Nine patients with DSRCT, 5 males and 4 females, with an average age of 21 years (range 8-56 years) were included in this study. Ultrasound examination revealed irregular low-density mass shadow in the abdominal cavity. CT examination found that 6 cases had abdominal and retroperitoneal multiple solid tumor nodules, uneven density, and visible low density fluid area. Postoperative pathological examination revealed that the tumor cells were small, mostly elliptic, gathered to form clear structure of nests with clear irregular boundaries. The central portion of large tumor nests often showed necrosis. Scattered fibroblasts and large amount of hyalinization of collagen fibers were seen in the interstitial tissue around the nests. Six patients received laparotomy surgery, however, all failed to resect the tumor completely. Three patients received postoperative chemotherapy, i. e. two cases had carboplatin and paclitaxel chemotherapy, and one case of chemotherapy regimen not specified. Two patients had radiation and chemotherapy (no concrete plan was available). Another case was lost to follow-up. Two of the three patients without surgery received chemotherapy with CAP (cyclophosphamide+adriamycin+carboplatin) and total rectal lesions, pelvic and inguinal lymph nodes, ilium metastases radiation therapy. Another one patient received EP regimen (DDP+VP16) which was then changed into a TP chemotherapy alone. Eight of the nine cases died shortly after surgery, and only one patient treated with chemotherapy alone was still alive after 11 months of follow-up. Desmoplastic small round cell tumor is a very rare, special type of soft tissue tumor, with very poor prognosis. This tumor may be preliminarily diagnosed according to the imaging characteristics and detection of tumor markers, however, final diagnosis is made by pathology. Surgery is the priority of treatment, combined with complementary radiation and chemotherapy.

Leaching characteristics of selected South African fly ashes: Effect of pH on the release of major and trace species

2009-07-01

Fly ash samples from two South African coal-fired power stations were subjected to different leaching tests under alkaline and acidic conditions in an attempt to assess the effect of pH on the leachability of species from the fly ashes and also assess the potential impact of the fly ashes disposal on groundwater and the receiving environment. To achieve this, German Standard leaching (DIN-S4) and Acid Neutralization Capacity (ANC) tests were employed. Ca, Mg, Na, K and SO{sub 4} were significantly leached into solution under the two leaching conditions with the total amounts in ANC leachates higher than that of DIN-S4.more » This indicates that a large fraction of the soluble salts in unweathered fly ash are easily leached. These species represents the fraction that can be flushed off initially from the surface of ash particles on contacting the ash with water. The amounts of toxic trace elements such as As, Se, Cd, Cr and Pb leached out of the fly ashes when in contact with de-mineralized water (DIN-S4 test) were low and below the Target Water Quality Range (TWQR) of South Africa. This is explained by their low concentrations in the fly ashes and their solubility dependence on the pH of the leaching solution. However the amounts of some minor elements such as B, Mn, Fe, As and Se leached out at lower pH ranging between 10 to 4 (ANC test) were slightly higher than the TWQR, an indication that the pH of the leaching solution plays a significant role on the leaching of species in fly ash. The high concentrations of the toxic elements released from the fly ashes at lower pH gives an indication that the disposal of the fly ash could have adverse effects on the receiving environment if the pH of the solution contacting the ashes is not properly monitored.« less

Visual exploration and analysis of ionospheric scintillation monitoring data: The ISMR Query Tool

Vani, Bruno César; Shimabukuro, Milton Hirokazu; Galera Monico, João Francisco

2017-07-01

Ionospheric Scintillations are rapid variations on the phase and/or amplitude of a radio signal as it passes through ionospheric plasma irregularities. The ionosphere is a specific layer of the Earth's atmosphere located approximately between 50 km and 1000 km above the Earth's surface. As Global Navigation Satellite Systems (GNSS) - such as GPS, Galileo, BDS and GLONASS - use radio signals, these variations degrade their positioning service quality. Due to its location, Brazil is one of the places most affected by scintillation in the world. For that reason, ionosphere monitoring stations have been deployed over Brazilian territory since 2011 through cooperative projects between several institutions in Europe and Brazil. Such monitoring stations compose a network that generates a large amount of monitoring data everyday. GNSS receivers deployed at these stations - named Ionospheric Scintillation Monitor Receivers (ISMR) - provide scintillation indices and related signal metrics for available satellites dedicated to satellite-based navigation and positioning services. With this monitoring infrastructure, more than ten million observation values are generated and stored every day. Extracting the relevant information from this huge amount of data was a hard process and required the expertise of computer and geoscience scientists. This paper describes the concepts, design and aspects related to the implementation of the software that has been supporting research on ISMR data - the so-called ISMR Query Tool. Usability and other aspects are also presented via examples of application. This web based software has been designed and developed aiming to ensure insights over the huge amount of ISMR data that is fetched every day on an integrated platform. The software applies and adapts time series mining and information visualization techniques to extend the possibilities of exploring and analyzing ISMR data. The software is available to the scientific community through the World Wide Web, therefore constituting an analysis infrastructure that complements the monitoring one, providing support for researching ionospheric scintillation in the GNSS context. Interested researchers can access the functionalities without cost at http://is-cigala-calibra.fct.unesp.br/, under online request to the Space Geodesy Study Group from UNESP - Univ Estadual Paulista at Presidente Prudente.

Artificial maturation of an immature sulfur- and organic matter-rich limestone from the Ghareb Formation, Jordan

An immature (Ro=0.39%), S-rich (S(org)/C = 0.07), organic matter-rich (19.6 wt. % TOC) limestone from the Ghareb Formation (Upper Cretaceous) in Jordan was artificially matured by hydrous pyrolysis (200, 220 ..., 300??C; 72 h) to study the effect of progressive diagenesis and early catagenesis on the amounts and distributions of hydrocarbons, organic sulfur compounds and S-rich geomacromolecules. The use of internal standards allowed the determination of absolute amounts. With increasing thermal maturation, large amounts of alkanes and alkylthiophenes with predominantly linear carbon skeletons are generated from the kerogen. The alkylthiophene isomer distributions do not change significantly with increasing thermal maturation, indicating the applicability of alkylthiophenes as biomarkers at relatively high levels of thermal maturity. For a given carbon skeleton, the saturated hydrocarbon, alkylthiophenes and alkylbenzo[b]thiophenes are stable forms at relatively high temperatures, whereas the alkylsulfides are not stable. The large amount of alkylthiophenes produced relative to the alkanes may be explained by the large number of monosulfide links per carbon skeleton. These results are in good agreement with those obtained previously for an artificial maturation series of an immature S-rich sample from the Gessoso-solfifera Formation.An immature (Ro = 0.39%), S-rich (Sorg/C = 0.07), organic matter-rich (19.6 wt.% TOC) limestone from the Ghareb Formation (Upper Cretaceous) in Jordan was artificially matured by hydrous pyrolysis (200, 220, ..., 300??C; 72 h) to study the effect of progressive diagenesis and early catagenesis on the amounts and distributions of hydrocarbons, organic sulfur compounds and S-rich geomacromolecules. The use of internal standards allowed the determination of absolute amounts. With increasing thermal maturation, large amounts of alkanes and alkylthiophenes with predominantly linear carbon skeletons are generated from the kerogen. The alkylthiophene isomer distributions do not change significantly with increasing thermal maturation, indicating the applicability of alkylthiophenes as biomarkers at relatively high levels of thermal maturity. For a given carbon skeleton, the saturated hydrocarbon, alkylthiophene and alkylbenzo[b]thiophenes are stable forms at relatively high temperatures, whereas the alkylsulfides are not stable. The large amount of alkylthiophenes produced relative to the alkanes may be explained by the large number of monosulfide links per carbon skeleton. These results are in good agreement with those obtained previously for an artificial maturation series of an immature S-rich sample from the Gessoso-solfifera Formation.

Nolan, Heather R.; Ramaiah, Chandrashekhar

2011-01-01

An increasing obese population in the United States focuses attention on the effect of obesity on surgical outcomes. Our objective was to see if obesity, determined by body mass index (BMI), contributed to bleeding in coronary artery bypass graft (CABG) surgery as measured by intraoperative and postoperative packed red blood cell transfusion frequency and amount and 24-hour chest-tube output. A retrospective chart review examined 150 subjects undergoing single-surgeon off-pump or on-pump CABG surgery between September 2006 and April 2009. BMI groups included normal-weight (BMI <25), overweight (BMI 25 to 29), and obese (BMI ≥30). Analyses used a chi-square test to determine variances in number of transfusions, and ANOVA for transfusion amount and 24-hour chest-tube amount. The percentage of subjects receiving intraoperative transfusions varied significantly by BMI group (p = 0.022). The percentage of subjects receiving transfusions in the 72-hour postoperative period showed a decreasing linear trend based on BMI group (p = 0.054). The percentage of subjects receiving transfusions in the combined intraoperative or 72-hour postoperative period showed a decreasing linear trend based on BMI group (p = 0.054). The transfusion amount during the 72-hour postoperative period varied significantly between BMI groups (p = 0.021), and the test for a linear decrease across groups was significant (p = 0.020). Twenty-four hour chest-tube output showed variation across all three BMI categories (p = 0.018) with chest-tube output decreasing with increasing obesity in a linear fashion (p = 0.006). Transfusion rate and amount indicate total blood loss is decreased in the obese, and chest-tube output findings give a direct measurable indicator of blood loss from the surgical site indicating increasing BMI is linearly correlated with decreasing postoperative bleeding.

To assess the short-term effects of instilling Y-27632, an inhibitor of Rho/Rho-associated protein kinases, on the chromatin supraorganization and DNA amount of corneal and limbal epithelial cells of healthy rats. Longitudinal sections (7 μm) of enucleated eyes of healthy rats that received, by instillation, balanced salt solution with or without 10 mM of Y-27632 daily for 7 or 15 days, were subjected to the Feulgen reaction. Feulgen-stained nuclei of corneal and limbal epithelial cells were studied by microscopy and video image analysis to establish the nuclear size (area and perimeter), supraorganization of chromatin (texture and degrees of condensation), and the Feulgen-DNA amount. Instillation of Y-27632 for up to 15 days did not change the size of the nucleus or the chromatin texture of corneal and limbal epithelial cells. Samples treated with Y-27632 for 7 days showed condensed chromatin and a high Feulgen-DNA amount. Both corneal and limbal epithelium showed the presence of near-tetraploid nuclei corresponding to cells in the S and G2 phases of the cell cycle. The degrees of condensation and Feulgen-DNA amount of the nuclei of epithelial cells of the cornea and limbus of eyes from rats receiving Y-27632 for 15 days did not differ from control (no drug). Changes in chromatin supraorganization and DNA amount, such as seen in this study, are indicative of cell proliferation and do not seem to be associated with disturbances in gene activity and transcription of DNA.

Crust and lithosphere structure in the eastern segment of the Xing-Meng orogenic belt from S-receiver function

Zhang, R.; Wu, Q.

2013-12-01

From 2009 to 2011, a 60 station broadband seismic array extending over 1200km was deployed in northeast China (NEC) by the Institute of geophysics, China Earthquake Administration (CEA). The recently linear deployment of seismic array in Northeast China (NEC) facilitated collection of more high-quality broadband data, thus provide us an opportunity to use S-wave receiver functions to investigate its crustal and mantle lithosphere structure with high resolution. Two distinct signals with large amplitude can be identified in our imaged S receiver functions. The strong positive one from the Moho can be observed continuously at depths from 40 km beneath Great Xing'an Range to less than 30 km beneath the Songliao Basin. The imaged Moho agrees with previous estimate of crustal thickness, and the lateral variations correlate to its surface tomography. The deep negative Sp phase interpreted as from the lithosphere-asthenosphere boundary (LAB) is as shallow as ~100km in the Songliao basin, down to 140-160km in the westward of Xingmeng block. The boundary is less prominent east of the Songliao Basin. The imaged Moho and LAB structure indicate the crust and lithosphere thinning in the Songliao Basin, and the vertical thinning of LAB is more obvious, evidence in a depth variation up to 50 km. The Songliao Basin is a continental rifting where a large amount of extension occurs, and the coupling of thinning between in the crust and underlying lithosphere indicated that the lithosphere stretching may be involved to the crustal rifting. The stretching can be more explained by the pure shear regime proposed in extensional tectonics. Acknowledgments.

Background/objective Length of stay (LOS) for rehabilitation treatment after spinal cord injury (SCI) has been documented extensively. However, there is almost no published research on the nature, extent, or intensity of the various treatments patients receive during their stay. This study aims at providing such information on a large sample of patients treated by specialty rehabilitation inpatient programs. Methods Six hundred patients with traumatic SCI admitted to six rehabilitation centers were enrolled. Time spent on various therapeutic activities was documented by each rehabilitation clinician after each patient encounter. Patients were grouped by neurologic level and completeness of injury. Total time spent by each rehabilitation discipline over a patient's stay and total minutes of treatment per week were calculated. Ordinary least squares stepwise regression models were used to identify patient and injury characteristics associated with time spent in rehabilitation treatment overall and within each discipline. Results Average LOS was 55 days (standard deviation 37), during which 180 (106) hours of treatment were received, or 24 (5) hours per week. Extensive variation was found in the amount of treatment received, between and within neurologic groups. Total hours of treatment provided throughout a patient's stay were primarily determined by LOS, which in turn was primarily predicted by medical acuity. Variation in minutes per week of treatment delivered by individual disciplines was predicted poorly by patient and injury characteristics. Conclusions Variations between and within SCI rehabilitation patient groups in LOS, minutes of treatment per week overall, and for each rehabilitation discipline are large. Variation in treatment intensity was not well explained by patient and injury characteristics. In accordance with practice-based evidence methodology, the next step in the SCIRehab study will be to determine which treatment interventions are related with positive outcomes (at 1 year post injury), after controlling for patient and injury differences.

Per capita allocation of overall development assistance has been shown to be biased towards countries with lower population size, meaning funders tend to provide proportionally less development assistance to countries with large populations. Individuals that happen to be part of large populations therefore tend to receive less assistance. However, no study has investigated whether this is also true regarding development assistance for health. We examined whether this so-called 'small-country bias' exists in the health aid sector. We analysed the effect of a country's population size on the receipt of development assistance for health per capita (in 2015 US$) among 143 countries over the period 1990-2014. Explanatory variables shown to be associated with receipt of development assistance for health were included: gross domestic product per capita, burden of disease, under-5 mortality rate, maternal mortality ratio, vaccination coverage (diphtheria, tetanus and pertussis) and fertility rate. We used the within-between regression analysis, popularised by Mundluck, as well as a number of robustness tests, including ordinary least squares, random-effects and fixed-effects regressions. Our results suggest there exists significant negative effect of population size on the amount of development assistance for health per capita countries received. According to the within-between estimator, a 1% larger population size is associated with a 0.4% lower per capita development assistance for health between countries (-0.37, 95% CI -0.45 to -0.28), and 2.3% lower per capita development assistance for health within countries (-2.29, 95% CI -3.86 to -0.72). Our findings support the hypothesis that small-country bias exists within international health aid, as has been previously documented for aid in general. In a rapidly changing landscape of global health and development, the inclusion of population size in allocation decisions should be challenged on the basis of equitable access to healthcare and health aid effectiveness.

Examining the implementation of NICE guidance: cross-sectional survey of the use of NICE interventional procedures guidance by NHS Trusts.

In the UK, NHS hospitals receive large amounts of evidence-based recommendations for care delivery from the National Institute for Health and Care Excellence (NICE) and other organisations. Little is known about how NHS organisations implement such guidance and best practice for doing so. This study was therefore designed to examine the dissemination, decision-making, and monitoring processes for NICE interventional procedures (IP) guidance and to investigate the barriers and enablers to the implementation of such guidance. A cross-sectional survey questionnaire was developed and distributed to individuals responsible for managing the processes around NICE guidance in all 181 acute NHS hospitals in England, Scotland, Wales and Northern Ireland. A review of acute NHS hospital policies for implementing NICE guidance was also undertaken using information available in the public domain and from organisations' websites. The response rate to the survey was 75 % with 135 completed surveys received. Additionally, policies from 25 % of acute NHS hospitals were identified and analysed. NHS acute hospitals typically had detailed processes in place to implement NICE guidance, although organisations recognised barriers to implementation including organisational process barriers, clinical engagement and poor targeting with a large number of guidance issued. Examples of enablers to, and good practice for, implementation of guidance were found, most notably the value of shared learning experiences between NHS hospitals. Implications for NICE were also identified. These included making improvements to the layout of guidance, signposting on the website and making better use of their shared learning platform. Most organisations have robust processes in place to deal with implementing guidance. However, resource limitations and the scope of guidance received by organisations create barriers relating to organisational processes, clinician engagement and financing of new procedures. Guidance implementation can be facilitated through encouragement of shared learning by organisations such as NICE and open knowledge transfer between organisations.

Distributed Processing of Projections of Large Datasets: A Preliminary Study

USGS Publications Warehouse

Maddox, Brian G.

2004-01-01

Modern information needs have resulted in very large amounts of data being used in geographic information systems. Problems arise when trying to project these data in a reasonable amount of time and accuracy, however. Current single-threaded methods can suffer from two problems: fast projection with poor accuracy, or accurate projection with long processing time. A possible solution may be to combine accurate interpolation methods and distributed processing algorithms to quickly and accurately convert digital geospatial data between coordinate systems. Modern technology has made it possible to construct systems, such as Beowulf clusters, for a low cost and provide access to supercomputer-class technology. Combining these techniques may result in the ability to use large amounts of geographic data in time-critical situations.

The unicellular red alga Galdieria sulphuraria grows efficiently and produces a large amount of biomass in acidic conditions at high temperatures. It has great potential to produce biofuels and other beneficial compounds without becoming contaminated with other organisms. In G. sulphuraria, biomass measurements and glycogen and lipid analyses demonstrated that the amounts and compositions of glycogen and lipids differed when cells were grown under autotrophic, mixotrophic, and heterotrophic conditions. Maximum biomass production was obtained in the mixotrophic culture. High amounts of glycogen were obtained in the mixotrophic cultures, while the amounts of neutral lipids were similar between mixotrophic and heterotrophic cultures. The amounts of neutral lipids were highest in red algae, including thermophiles. Glycogen structure and fatty acids compositions largely depended on the growth conditions. Copyright © 2015.

Impact of Aerosols on Atmospheric Attenuation Loss in Central Receiver Systems: Preprint

Sengupta, M.; Wagner, M. J.

2011-08-01

Atmospheric attenuation loss between the heliostat field and receiver has been recognized as a significant source of loss in Central Receiver Systems. In clear sky situations, extinction of Direct Normal Irradiance (DNI) is primarily by aerosols in the atmosphere. When aerosol loading is high close to the surface the attenuation loss between heliostat and receivers is significantly influenced by the amount of aerosols present on a particular day. This study relates measured DNI to aerosol optical depths close to the surface of the earth. The model developed in the paper uses only measured DNI to estimate the attenuation between heliostatmore » and receiver in a central receiver system. The requirement that only a DNI measurement is available potentially makes the model a candidate for widespread use.« less

Openwebglobe 2: Visualization of Complex 3D-GEODATA in the (mobile) Webbrowser

2016-06-01

Providing worldwide high resolution data for virtual globes consists of compute and storage intense tasks for processing data. Furthermore, rendering complex 3D-Geodata, such as 3D-City models with an extremely high polygon count and a vast amount of textures at interactive framerates is still a very challenging task, especially on mobile devices. This paper presents an approach for processing, caching and serving massive geospatial data in a cloud-based environment for large scale, out-of-core, highly scalable 3D scene rendering on a web based virtual globe. Cloud computing is used for processing large amounts of geospatial data and also for providing 2D and 3D map data to a large amount of (mobile) web clients. In this paper the approach for processing, rendering and caching very large datasets in the currently developed virtual globe "OpenWebGlobe 2" is shown, which displays 3D-Geodata on nearly every device.

Does motivational interviewing counseling time influence HIV-positive persons' self-efficacy to practice safer sex?

This study examined the impact of motivational interviewing (MI) counseling time on self-efficacy to practice safer sex for people living with HIV/AIDS (PLWHA). In 4 month intervals we followed a cohort of 490 PLWHA for 12 months. We conducted hierarchical linear regression models to examine changes in safer sex self-efficacy when participants received zero, low to moderate (5-131 min) and high (132-320 min) doses of MI time. We conducted a similar analysis using number of counseling sessions as the predictor variable. Participants with low to moderate doses of MI counseling had 0.26 higher self-efficacy scores than participants with zero MI time (p=0.01). Also, they had 0.26 lower self-efficacy scores than participants with high amounts of MI time (p=0.04). Participants with high doses of MI had a 0.5 higher self-efficacy score than participants with zero amount of MI time (p<0.0001). Participants who received 3-4 counseling sessions had 0.41 greater self-efficacy scores than participants who did not receive any sessions (p<0.0001) but did not differ from participants receiving 1-2 sessions. MI time is a key to enhancing safer sex self-efficacy among PLWHA. Safer sex self-efficacy improves the more MI counseling time and sessions PLWHA receive. Copyright © 2011 Elsevier Ireland Ltd.

Patients' willingness to pay for pharmaceutical care.

Larson, R A

2000-01-01

To determine the level at which patients receive pharmaceutical care services and their willingness to pay for comprehensive pharmaceutical care services. A mail survey was sent to 2,500 adults in the United States. Surveys were mailed to subjects' homes. Subjects were randomly selected from a marketing database that included representation from each of the 50 states of the United States. The survey provided a description of comprehensive pharmaceutical care, and survey items asked about the level of care subjects were receiving and their willingness to pay for these services. Level of various pharmacy services subjects reported receiving, and the dollar amount subjects were willing to pay for comprehensive pharmaceutical care. The majority of the subjects were not receiving pharmaceutical care services. The average amount all respondents were willing to pay for these services was $13 for a one-time consultation and $28 for this plus 1 year of monitoring. Looking only at those respondents willing to pay (56%), the means rise to $23 and $50, respectively. A majority of patients are willing to pay for pharmaceutical care services, even if they are not now receiving this level of care. Direct payment from patients who recognize the therapeutic benefits of pharmaceutical care may be a more viable option than is generally believed, at least until the profession can prove pharmaceutical care's utility and cost-effectiveness to third party payers.

Gratitude depends on the relational model of communal sharing.

PubMed

Simão, Cláudia; Seibt, Beate

2014-01-01

We studied the relation between benefits, perception of social relationships and gratitude. Across three studies, we provide evidence that benefits increase gratitude to the extent to which one applies a mental model of a communal relationship. In Study 1, the communal sharing relational model, and no other relational models, predicted the amount of gratitude participants felt after imagining receiving a benefit from a new acquaintance. In Study 2, participants recalled a large benefit they had received. Applying a communal sharing relational model increased feelings of gratitude for the benefit. In Study 3, we manipulated whether the participant or another person received a benefit from an unknown other. Again, we found that the extent of communal sharing perceived in the relationship with the stranger predicted gratitude. An additional finding of Study 2 was that communal sharing predicted future gratitude regarding the relational partner in a longitudinal design. To conclude, applying a communal sharing model predicts gratitude regarding concrete benefits and regarding the relational partner, presumably because one perceives the communal partner as motivated to meet one's needs. Finally, in Study 3, we found in addition that being the recipient of a benefit without opportunity to repay directly increased communal sharing, and indirectly increased gratitude. These circumstances thus seem to favor the attribution of communal norms, leading to a communal sharing representation and in turn to gratitude. We discuss the importance of relational models as mental representations of relationships for feelings of gratitude.

Again, we found that the extent of communal sharing perceived in the relationship with the stranger predicted gratitude. An additional finding of Study 2 was that communal sharing predicted future gratitude regarding the relational partner in a longitudinal design. To conclude, applying a communal sharing model predicts gratitude regarding concrete benefits and regarding the relational partner, presumably because one perceives the communal partner as motivated to meet one's needs. Finally, in Study 3, we found in addition that being the recipient of a benefit without opportunity to repay directly increased communal sharing, and indirectly increased gratitude. These circumstances thus seem to favor the attribution of communal norms, leading to a communal sharing representation and in turn to gratitude. We discuss the importance of relational models as mental representations of relationships for feelings of gratitude. PMID:24465933

Whole exome sequencing (WES) uses next generation sequencing technology to provide information on nearly all functional, protein-coding regions in an individual's genome. Due to the vast amount of information and incidental findings that can be generated from this technology, patient preferences must be investigated to help clinicians consent and return results to patients. Patients (n=19) who were previously clinically diagnosed with Lynch syndrome, but received uninformative negative Lynch syndrome genetic results through traditional molecular testing methods participated in semi-structured interviews after WES testing but before return of results to explore their views of WES and preferences for return of results. Analyses of interview results found that nearly all participants believed that the benefits of receiving all possible results generated from WES outweighed the undesirable effects. The majority of participants conveyed that relative to coping with a cancer diagnosis, information generated from WES would be manageable. Importantly, participants' experience with Lynch syndrome influenced their notions of genetic determinism, tolerance for uncertain results, and family communication plans. Participants would prefer to receive WES results in person from a genetic counselor or medical geneticist so that an expert could help explain the meaning and implications of the potentially large quantity and range of complicated results. These results underscore the need to study various populations with regard to the clinical use of WES in order to effectively and empathetically communicate the possible implications of this new technology and return results.

Aerosols attenuating the solar radiation collected by solar tower plants: The horizontal pathway at surface level

Aerosols attenuate the solar radiation collected by solar tower plants (STP), along two pathways: 1) the atmospheric column pathway, between the top of the atmosphere and the heliostats, resulting in Direct Normal Irradiance (DNI) changes; 2) the grazing pathway close to surface level, between the heliostats and the optical receiver. The attenuation along the surface-level grazing pathway has been less studied than the aerosol impact on changes of DNI, while it becomes significant in STP of 100 MW or more. Indeed aerosols mostly lay within the surface atmospheric layer, called the boundary layer, and the attenuation increases with the distance covered by the solar radiation in the boundary layer. In STP of 100 MW or more, the distance between the heliostats and the optical receiver becomes large enough to produce a significant attenuation by aerosols. We used measured aerosol optical thickness and computed boundary layer height to estimate the attenuation of the solar radiation at surface level at Ouarzazate (Morocco). High variabilities in aerosol amount and in vertical layering generated a significant magnitude in the annual cycle and significant inter-annual changes. Indeed the annual mean of the attenuation caused by aerosols over a 1-km heliostat-receiver distance was 3.7% in 2013, and 5.4% in 2014 because of a longest desert dust season. The monthly minimum attenuation of less than 3% was observed in winter and the maximum of more than 7% was observed in summer.

Sources of material for 'loess' deposits at 15°N in North Africa

NASA Astrophysics Data System (ADS)

McLaren, Sue; Smalley, Ian; O'Hara-Dhand, Ken

2014-05-01

Africa is not a loess-rich continent. Lacking are the large expanses of glacial terrain and the high cold mountain regions, which would have provided the material and processes for loess deposits. African geomorphology and climatic history did not favour the formation of major loess deposits. However, within the African setting there are situations which could lead to particle formation and loess deposition. Loess deposits are made from 'large' dust (i.e. particles around 30µm). Small dust (around 3µm) is generated in large amounts in Africa, and distributed over large distances. Large dust is not generated in significant amounts in Africa, and this accounts for the relative lack of loess deposits. It is a relative lack; examination of the map of loess distribution in the World by Scheidig 1934 (still the best world loess map) shows some possible loess in Africa. In particular there is a band across the continent at around 15°N. We propose some possible sources for this material, and fit these sources into a recently revised deterministic model of loess deposit formation. And look at some exotic but possible indicators of the loessic nature of the 15°N band. Three possible material sources are: (1). The Fonta-Djalon highlands to the west of the loess band, (2). The Bodélé Depression, towards the centre of the loess band, and (3). The Ethiopian highlands to the east. There is a convenient river associated with the loess band; the Niger rises in the Fonta-Djalon region and carries material through the loess zone. The catchment of the Niger is well placed to receive large dust material from the Bodélé depression. Most Bodélé material is small dust carried away in high suspension but small amounts of large dust could be transported to the Niger catchment. Material from the Ethiopian highlands makes up the Nile silt but again some could be transported to the west to contribute to the loess band- which is a modest loess deposit. The deposit can be examined with respect to the deterministic model of loess deposit formation which sets out four event aspects which must be accommodated. PTDC: provenance (of material), transportation, deposition and change- all need to be considered when loess deposit genesis is examined. In the case of the 15°N loess the P actions are speculative, and probably not very effective. In fact the deposits they deliver, as mapped by Scheidig, still have to be established as genuine loess. There are indicators of loessic nature; one is that they are favoured by tunnel nesting birds, in particular bee-eaters. Merops apiaster (the European bee-eater) travels large distances to nest in the European loess. The bee-eater nesting zones map nicely on to European loess distribution. In the 15°N zone there is a concentration of nesting activity by the Northern Carmine bee-eater (Merops nubicus) and we take this as an indicator of ground nature.

Tribological properties of sintered polycrystalline and single crystal silicon carbide

Miyoshi, K.; Buckley, D. H.; Srinivasan, M.

1982-01-01

Tribological studies and X-ray photoelectron spectroscopy analyses were conducted with sintered polycrystalline and single crystal silicon carbide surfaces in sliding contact with iron at various temperatures to 1500 C in a vacuum of 30 nPa. The results indicate that there is a significant temperature influence on both the friction properties and the surface chemistry of silicon carbide. The main contaminants on the as received sintered polycrystalline silicon carbide surfaces are adsorbed carbon, oxygen, graphite, and silicon dioxide. The surface revealed a low coefficient of friction. This is due to the presence of the graphite on the surface. At temperatures of 400 to 600 C graphite and copious amount of silicon dioxide were observed on the polycrystalline silicon carbide surface in addition to silicon carbide. At 800 C, the amount of the silicon dioxide decreased rapidly and the silicon carbide type silicon and carbon peaks were at a maximum intensity in the XPS spectra. The coefficients of friction were high in the temperature range 400 to 800 C. Small amounts of carbon and oxygen contaminants were observed on the as received single crystal silicon carbide surface below 250 C. Silicon carbide type silicon and carbon peaks were seen on the silicon carbide in addition to very small amount of graphite and silicon dioxide at temperatures of 450 to 800 C.

The Geomorphic Role of Large Woody Debris in River Avulsions

NASA Astrophysics Data System (ADS)

Stout, J. C.; Grove, J. R.; Rutherfurd, I.; Marren, P.

2014-12-01

The avulsion or abandonment of a river channel in favor of a new course on the floodplain is integral to the development and maintenance of anabranching planforms. Avulsions tend to occur on rivers where the rate of vertical aggradation outpaces lateral migration. In fine cohesive floodplain sediments, avulsions evolve through five stages dependent on the amount of flow and sediment being captured by the new channel. There is limited data available to allow the prediction of autogenic and allogenic controls on: the time over which an avulsion is active; its likely location; the frequency of occurrence; and the length of the interavulsion period. The delivery of wood to the river channel is an autogenic process which has received much attention over the last three decades. Surprisingly it has not previously been considered in anabranch avulsions, apart from where log-jams entirely block channels. The presence of large woody debris in the channel acts as a roughness element, trapping, and impeding the movement of sediments and deflecting flow onto the floodplain. We hypothesize that the delivery rates of wood to the channel, and its subsequent configuration (i.e. dimension, amount, volume, spatial arrangement and blockage ratio), alters flow and sediment routing through the channel. These changes directly influence the stages of avulsion development. To test this conceptual model we have used eleven floodplain cores to reconstruct the timing of a Holocene avulsion. The morphology of the channel in each evolutionary stage was used to estimate the relative role of wood as a roughness element. This was done by coupling a mass balance wood delivery model, run in a Monte Carlo simulation, to the geomorphic processes of each evolutionary stage of the avulsion. Our results allow us to quantify the importance of in-channel wood during each stage of the avulsion. These data highlight that there are critical points in the evolution of anabranching channels when large wood influences the avulsion rate and location.

Diffractometer data collecting method and apparatus

Diffractometer data is collected without the use of a movable receiver. A scanning device, positioned in the diffractometer between a sample and detector, varies the amount of the beam diffracted from the sample that is received by the detector in such a manner that the beam is detected in an integrated form. In one embodiment, a variable diameter beam stop is used which comprises a drop of mercury captured between a pair of spaced sheets and disposed in the path of the diffracted beam. By varying the spacing between the sheets, the diameter of the mercury drop is varied. In another embodiment, an adjustable iris diaphragm is positioned in the path of the diffracted beam and the iris opening is adjusted to control the amount of the beam reaching the detector. 5 figures.

Dartmouth College provided a single-channel high-frequency wave receiver to the Sounding of the Ion Energization Region: Resolving Ambiguities (SIERRA) rocket experiment launched from Poker Flat, Alaska, in January 2002. The receiver used signals from booms, probes, preamplifiers, and differential amplifiers provided by Cornell University coinvestigators. Output was to a dedicated 5 MHz telemetry link provided by WFF, with a small amount of additional Pulse Code Modulation (PCM) telemetry required for the receiver gain information. We also performed preliminary analysis of the data. The work completed is outlined below, in chronological order.

Parecoxib provides analgesia following a variety of surgeries, including minor gastrointestinal procedures. To our knowledge, there is no data on parecoxib following major gastrointestinal surgery. This study assessed the efficacy and opioid-sparing effects of parecoxib following major gastrointestinal surgeries. Patients in this analysis were a subset from a large, randomized, double-blind, placebo-controlled trial of parecoxib following noncardiac surgeries and consisted of those undergoing a variety of major gastrointestinal surgeries via laparotomy. Pain, pain interference with function, supplemental opioid utilization, opioid-related symptoms, and Patient/Physician Global Evaluation of Study Medication were compared between placebo and parecoxib groups in the 2-3 days following surgery. Significantly ( p <0.001) lower pain scores were observed in the parecoxib group (n=111), relative to placebo (n=126), on Day 2 (-33%) and Day 3 (-35%). Pain interference with function scores was also significantly ( p <0.001) lower among patients receiving parecoxib compared with placebo on Day 2 (-29%) and Day 3 (-36%). At 24, 48, and 72 hours, the cumulative amount of supplemental morphine consumed was 45%, 41%, and 40% less in patients receiving parecoxib compared with placebo (all p <0.001). The risk of experiencing ≥1 opioid-related symptoms was also significantly lower with parecoxib than with placebo on Day 2 (relative risk=0.75; p <0.001). Specifically, the risks of fatigue and drowsiness were significantly (both p <0.05) lower in patients receiving parecoxib compared to those receiving placebo. Patient and Physician Global Evaluation of Study Medication scores were significantly better in the parecoxib group than in the placebo group ( p <0.001). This study is the first to demonstrate that multiple-dose parecoxib, initiated upon recovery from anesthesia, provides analgesia and opioid-sparing effects following a variety of major gastrointestinal surgeries employing laparotomy.

Observational Analysis of Two Contrasting Monsoon Years

The Indian summer monsoon rainfall contributes about 75 % of the total annual rainfall and exhibits considerable interannual variations. The agricultural economy of the country depends mainly on the monsoon rainfall. The long-range forecast of the monsoon rainfall is, therefore of significant importance in agricultural planning and other economic activities of the country. There are various parameters which influence the amount of rainfall received during the monsoon. Some of the important parameters considered by the Indian Meteorological Department (IMD) for the study of monsoon are Outgoing Longwave Radiation (OLR), moisture content of the atmosphere, zonal wind speed, low level vorticity, pressure gradient etc. Compared to the Long Period Average (LPA) value of rain fall, the country as a whole received higher amount of rainfall in June, 2013 (34 % more than LPA). The same month showed considerable decrease next year as the amount of rainfall received was around 43 % less compared to LPA. This drastic difference of monsoon prompted to study the behaviour of some of the monsoon relevant parameters. In this study we have considered five atmospheric parameters as the indicators of monsoon behaviour namely vertical relative humidity, OLR, aerosol optical depth (AOD), wind at 850 hPa and mean sea level pressure (MSLP). In the initial analysis of weekly OLR difference for year 2013 and 2014 shows positive values in the month of May over north-western parts of India (region of heat low). This should result in a weaker monsoon in 2014. This is substantiated by the rainfall data received for various stations over India. Inference made based on the analysis of RH profiles coupled with AOD values is in agreement with the rainfall over the corresponding stations.

Exploring the Industry-Dermatologist Financial Relationship: Insight From the Open Payment Data.

Significant ties exist between clinicians and industry. Little is known about the characteristics of industry payments to dermatologists. To analyze the nature and extent of industry payments to dermatologists. This was a retrospective review using the publicly available Centers for Medicare and Medicaid Services (CMS) Sunshine Act Open Payment database. Data were downloaded from the publically available CMS website under General Payment and Research Payment data sets. All payments to dermatologists from companies making products reimbursed by a government-run health program were reviewed. Mean, median, and range of payments made, including quantity and total sum of payments, per clinician. Total payments and number of transactions per category of payment, geographic region, and payment source were also assessed. A total of 8333 dermatologists received 208 613 payments totaling more than $34 million. The median total payment per dermatologist was $298 with an interquartile range of $99 to $844. The top 10% of dermatologists (n = 833) received more than $31.2 million, 90% of the total payments. The top 1% each (n = 83) received at least $93 622 and accounted for 44% of total payments. While 83% of payment entries were for food and beverage, they accounted for only 13% of total amount of payments. Speaker fees (31.7%), consulting fees (21.6%), and research payments (16.5%) comprised 69.8% of total payment amount. The top 15 companies were all pharmaceutical manufacturers and paid dermatologists $28.7 million, representing 81% of total disbursement. Dermatologists received substantial payments from the pharmaceutical industry. The nature and amount of payments varied widely. The impact of the data on patient care, physicians practice patterns, and patient perception of physicians is unclear.

To analyze research and nonresearch payments from the pharmaceutical and device industry to neurologists in 2015 using the Centers for Medicare and Medicaid Services (CMS) Open Payments database. In this retrospective database analysis, we computed the percentage of neurologists in the United States receiving payments, the median/mean payments per neurologist, payment categories, regional trends, and sponsors. We computed the number of practicing neurologists from the Association of American Medical Colleges State Physician Workforce data book, 2015. In 2015, approximately 51% of US neurologists received nonresearch payments totaling $6,210,414. The median payment per physician was $81. Payments to the top 10% of compensated neurologists amounted to $5,278,852 (84.5%). Food and beverage was the most frequent category (86.5% of the total number of payments). The highest amount was paid for serving as faculty/speaker for non-continuing medical education activities (58%). The top sponsor of nonresearch payments was Teva Pharmaceuticals ($1,162,900; 18.5%). A total of 412 neurologists received $2,921,611 in research payments (median $1,132). Multiple sclerosis specialists received the largest proportion ($285,537; 9.7%). Daiichi Sankyo paid the largest amount in research payments ($826,029; 28%). The Open Payments program was established to foster transparent disclosure of physician compensation from industry, in response to legislative and public concerns over the effect of conflicts of interest on practice, education, and research. The effects of this program remain unclear and studies of changes in prescribing practices, costs, and other outcomes are necessary. CMS should ensure that incorrect information can be rectified quickly and easily. © 2018 American Academy of Neurology.

Adrenal steroid inhibition of the vasopressin-neurophysin neurosecretory system to the median eminence of the rat. Differential effects of corticosterone and deoxycorticosterone administration after adrenalectomy.

Neurophysin and vasopressin-containing terminals in the zona externa of the median eminence (ZE) show a large increase in immunoreactive peptide following adrenalectomy which can be prevented by dexamethazone replacement therapy. The present study was undertaken to determine the effectiveness of a glucocorticoid (corticosterone; CS) and a mineralocorticoid (deoxycorticosterone: DOC) in exerting negative feedback on this system. Animals were adrenalectomized and implanted with various sized pellets of either steroid or cholesterol. The amount of neurophysin-immunoreactivity in the ZE 2 weeks after adrenalectomy was estimated on a zero to four rank scale independently by three observers. The data were analyzed by the X2 statistic. Low doses of CS (50 mg) reduced the amount of staining in comparison to cholesterol-replaced animals by approximately 50%. The ZE of animals receiving higher doses (100--200 mg) were identical to those of intact animals. DOC, however, at the 50 or 100 mg level produced only a slight inhibition of the response to adrenalectomy. Larger pellets (150--200 mg) did not result in a level of ZE staining as low as for intact animals. These findings suggest that the vasopressin neurosecretory system to the ZE is regulated by glucocorticoids.

ASCORBIC ACID RETENTION AND COLOR OF STRAWBERRIES AS RELATED TO LOW-LEVEL IRRADIATION AND STORAGE TIME

Freshly picked strawberries were irradiated in a gamma source and ascorbic acid (ASA) and its oxidative breakdown products were measured at intervals during 3 to 6 months' storage. Reduced ASA, dehydroascorbic acid (DHA), diketogulonic acid (DKA), and total ASA were determined in unirradiated strawberries and in strawberries receiving 0.3 and 0.8 Mrad. Irradiation caused a significant loss of total ASA. Storage at 35 un. Concent 85% F for 180 days resulted in further losses, most of which occurred during the first 95 days. Addition of a glucose oxidase packet to atmospheric packs did not affect retention of total ASA. Amore » significant amount of reduced ASA was destroyed by irradiation, the loss being greater at the higher level used. Relatively large amounts er irradiation in the presence of almost complete retention of total ASA indicated that the degradation followed the usual pattern: reduced ASA to DHA to DKA. After 180 days storage, practically all of the reduced ASA was destroyed in air-packed irradiated samples, but comparable glucose-oxidase-packed samples retained 33 to 47% of their original reduced ASA. Measurement of the Gardner a color value revealed a significant able color variability among samples. Color losses were higher at higher doses. (H.R.D.)« less

Speech intelligibility in complex acoustic environments in young children

2003-04-01

While the auditory system undergoes tremendous maturation during the first few years of life, it has become clear that in complex scenarios when multiple sounds occur and when echoes are present, children's performance is significantly worse than their adult counterparts. The ability of children (3-7 years of age) to understand speech in a simulated multi-talker environment and to benefit from spatial separation of the target and competing sounds was investigated. In these studies, competing sources vary in number, location, and content (speech, modulated or unmodulated speech-shaped noise and time-reversed speech). The acoustic spaces were also varied in size and amount of reverberation. Finally, children with chronic otitis media who received binaural training were tested pre- and post-training on a subset of conditions. Results indicated the following. (1) Children experienced significantly more masking than adults, even in the simplest conditions tested. (2) When the target and competing sounds were spatially separated speech intelligibility improved, but the amount varied with age, type of competing sound, and number of competitors. (3) In a large reverberant classroom there was no benefit of spatial separation. (4) Binaural training improved speech intelligibility performance in children with otitis media. Future work includes similar studies in children with unilateral and bilateral cochlear implants. [Work supported by NIDCD, DRF, and NOHR.

Aerosols in Alaska

We are measuring the latitudinal gradient and time variation of aerosol chemical composition across Alaska looking for drifts that might be attributable to alteration in sources and chemical signatures that might allow the identification of sources. Alaska is a very clean region in the sense that the state has a low population density with little polluting emission sources. However it "receives" anthropogenic chemical signals from areas upstream in the westerly's, such as from China, and impacts of Arctic Haze. The region also generates sometime copious amounts of aerosol from wildfire in its boreal forests and condensed compounds from gases emitted by its surrounding oceans. The time series of aerosol composition from this small network goes back about a decade and shows clearly the spring peaking of anthropogenic signal known as Arctic Haze. This signal peaks year after year in spring months at all stations, but is most concentrated at north most stations. On the other hand, a signal indicative of products from the ocean, mainly sulfate with large fractional amounts of MSA peaks, year after year, in the summer and is strongest at the lower latitudes. We have identified not only chemical signatures associated with wildfire smoke from wildfires in Alaska, but the changed signatures from wildfires in far away regions, from Mongolia for example.

Denitrifying capability of glycogen accumulating organisms (GAOs) has received great attention in environmental science and microbial ecology. Combining this ability with granule processes would be an interesting attempt. Here, a laboratory-scale sequencing batch reactor (SBR) was operated to enrich GAOs and enable sludge granulation. The results showed that the GAO granules were cultivated successfully and the granules had denitrifying capability. The batch experiments demonstrated that all NO3−-N could be removed or reduced, some amount of NO2−-N were accumulated in the reactor, and N2 was the main gaseous product. SEM analysis suggested that the granules were tightly packed with a large amount of tetrad-forming organisms (TFOs); filamentous bacteria served as the supporting structures for the granules. The microbial community structure of GAO granules was differed substantially from the inoculant conventional activated sludge. Most of the bacteria in the seed sludge grouped with members of Proteobacterium. FISH analysis confirmed that GAOs were the predominant members in the granules and were distributed evenly throughout the granular space. In contrast, PAOs were severely inhibited. Overall, cultivation of the GAO granules and utilizing their denitrifying capability can provide us with a new approach of nitrogen removal and saving more energy. PMID:26257096

Denitrifying capability of glycogen accumulating organisms (GAOs) has received great attention in environmental science and microbial ecology. Combining this ability with granule processes would be an interesting attempt. Here, a laboratory-scale sequencing batch reactor (SBR) was operated to enrich GAOs and enable sludge granulation. The results showed that the GAO granules were cultivated successfully and the granules had denitrifying capability. The batch experiments demonstrated that all NO3--N could be removed or reduced, some amount of NO2--N were accumulated in the reactor, and N2 was the main gaseous product. SEM analysis suggested that the granules were tightly packed with a large amount of tetrad-forming organisms (TFOs); filamentous bacteria served as the supporting structures for the granules. The microbial community structure of GAO granules was differed substantially from the inoculant conventional activated sludge. Most of the bacteria in the seed sludge grouped with members of Proteobacterium. FISH analysis confirmed that GAOs were the predominant members in the granules and were distributed evenly throughout the granular space. In contrast, PAOs were severely inhibited. Overall, cultivation of the GAO granules and utilizing their denitrifying capability can provide us with a new approach of nitrogen removal and saving more energy.

Student performance on conceptual questions: Does instruction matter?

As part of the tutorial component of introductory calculus-based physics at the University of Washington, students take weekly pretests that consist of conceptual questions. Pretests are so named because they precede each tutorial, but they are frequently administered after lecture instruction. Many variables associated with class composition and prior instruction (if any) could, in principle, affect student performance on these questions. Nonetheless, the results are often found to be "essentially the same" in all classes. With data available from a large number of classes, it is possible to characterize the typical variation quantitatively. In this paper three questions for which we have accumulated thousands of responses, from dozens of classes representing different conditions with respect to the textbook in use, the amount of prior instruction, etc., serve as examples. For each question, we examine the variation in student performance across all classes. We also compare subsets categorized according to the amount of relevant prior instruction each class had received. A preliminary analysis suggests that the variation in performance is essentially random. No statistically significant difference is observed between results obtained before relevant instruction begins and after it has been completed. The results provide evidence that exposure to concepts in lecture and textbook is not sufficient to ensure an improvement in performance on questions that require qualitative reasoning.

Fatty acid esters extractable from the surface of honey bee, Apis mellifera L. (Hymenoptera: Apidae), larvae, called brood pheromone, significantly increase rate of colony growth in the spring and summer when flowering plant pollen is available in the foraging environment. Increased colony growth rate occurs as a consequence of increased pollen intake through mechanisms such as increasing number of pollen foragers and pollen load weights returned. Here, we tested the hypothesis that addition of brood pheromone during the winter pollen dearth period of a humid subtropical climate increases rate of colony growth in colonies provisioned with a protein supplement. Experiments were conducted in late winter (9 February-9 March 2004) and mid-winter (19 January-8 February 2005). In both years, increased brood area, number of bees, and amount of protein supplement consumption were significantly greater in colonies receiving daily treatments of brood pheromone versus control colonies. Amount of extractable protein from hypopharyngeal glands measured in 2005 was significantly greater in bees from pheromone-treated colonies. These results suggest that brood pheromone may be used as a tool to stimulate colony growth in the southern subtropical areas of the United States where the package bee industry is centered and a large proportion of migratory colonies are overwintered.
