K-pop, Indonesian fandom, and social media

Directory of Open Access Journals (Sweden)

Sun Jung

2011-11-01

Full Text Available Around the world, pop consumers are increasingly accessing popular products through social media. Online fan groups of Korean popular music (K-pop in Asia have dynamically and transculturally circulated their product through social media such as Facebook and Twitter. In October 2010, Super Junior, a K-pop idol boy band, was ranked as the number one worldwide trending topic on Twitter—ranking even higher than a sensational news story about trapped Chilean miners. Regional fans in Indonesia in particular have been identified as the source of a spike in tweets on this topic. Such a phenomenon illustrates how social media–empowered online fandom enhances cultural flow and affects transcultural pop circulation dynamics. I examine these dynamics by means of the specific case study of K-pop fandom in Indonesia. By focusing on three specific aspects of new media circulation of K-pop in Indonesia—performing immediate transculturations, embodying K-pop, and building intimacies—I contextualize transnationally focused, newly emerging, and social media–deployed cultural circulation driven by online fan practices.

In the Great Lakes, introduced Pacific salmon (Oncorhynchus spp.) can transport persistent organic pollutants (POPs), such as polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), to new environments during their spawning migrations. To explore the nature and extent of POP biotransport by salmon, we compared 58 PCB and 6 PBDE congeners found in spawning salmon directly to those in resident stream fish. We hypothesized that stream fish exposed to salmon spawners would have congener patterns similar to those of salmon, the presumed contaminant source. Using permutational multivariate analysis of variance (PERMANOVA) and nonmetric multidimensional scaling (NMDS), we found that POP congener patterns of Pacific salmon varied among regions in the Great Lakes basin (i.e., Lake Huron, Lake Michigan, or Lake Superior), tissue type (whole fish or eggs), and contaminant type (PCB or PBDE). For stream-resident fish, POP congener pattern was influenced by the presence of salmon, location (i.e., Great Lakes Basin), and species identity (i.e., brook trout [Salvelinus fontinalis] or mottled sculpin [Cottus bairdii]). Similarity in congener patterns indicated that salmon are a source of POPs to brook trout in stream reaches receiving salmon spawners from Lake Michigan and Lake Huron but not from Lake Superior. Congener patterns of mottled sculpin differed from those of brook trout and salmon, suggesting that brook trout and mottled sculpin either use salmon tissue to differing degrees, acquire POPs from different dietary sources, or bioaccumulate or metabolize POPs differently. Overall, our analyses identified the important role of salmon in contaminant biotransport but also demonstrated that the extent of salmon-mediated POP transfer and uptake in Great Lakes tributaries is location- and species-specific.

Through the Microscope: Understanding "The Tempest" in the Context of the Introduction to Pico della Mirandola’s "Oration on the Dignity of Man"

Directory of Open Access Journals (Sweden)

Michaela Krämer

2016-12-01

Full Text Available In the format of interpretation the creative laboratory of Shakespeare’s “The Tempest” is being revealed. By all accounts “The Tempest” has no specific sources. This study, however, supposes, that Shakespeare could refer to the basic concept and, from this perspective, even very closely rely on the details. Hence, it is proved, that the philosophical impulse of Shakespeare’s tragedy can be considered the introduction to the “Oration on the Dignity of Man” by Giovanni Pico della Mirandola, created for the forbidden later theological discussions on relevant topics in Rome (1486, which dealt with the possibility of moral self-determination and individual responsibility. Imposing the lines of the treatise by Pico on the images and plot of the drama by Shakespeare, we immediately notice a twisted three-dimensional image, the transition from abstract relationship to the visible processes of existence and consciousness, at the same time fantastic and real. This analysis is based on the statement, that “The Tempest” can be interpreted as the staging of memorable images of Pico. This statement is relevant to point of view, according to which Shakespeare could choose the idea of the Oration, or directly from the passage of the text. Shakespeare consciously goes beyond the ideas of Pico. If the quotations from the text of Pico are considered as a subtext, it immediately becomes evident that scene, characters and action of the play are based in some way on a complex conceptual scheme. With the underlying meaning of the Oration by Pico, “The Tempest” is a powerful creative experiment and a reasonable appeal to the uniqueness of human life and spiritual freedom of a man. Thus, this study, without resorting to discuss specific aspects of the play, aspires to promote scientific debate about its hidden meaning.

UniPOPS, a suite of programs and utilities developed at the National Radio Astronomy Observatory (NRAO), reduced data from the observatory's single-dish telescopes: the Tucson 12-m, the Green Bank 140-ft, and archived data from the Green Bank 300-ft. The primary reduction programs, 'line' (for spectral-line reduction) and 'condar' (for continuum reduction), used the People-Oriented Parsing Service (POPS) as the command line interpreter. UniPOPS unified previous analysis packages and provided new capabilities; development of UniPOPS continued within the NRAO until 2004 when the 12-m was turned over to the Arizona Radio Observatory (ARO). The submitted code is version 3.5 from 2004, the last supported by the NRAO.

[Death and the pop musician].

Science.gov (United States)

de Leeuw, Peter W

2011-01-01

Many people are inclined to believe that popular music artists are prone to die prematurely. Scientific research into this matter is scarce. There is only one epidemiological study on this subject, showing that mortality among pop stars during the first 25 years after they became famous is increased. This mortality is higher in Northern America than it is in Europe, but European pop stars die on average at an earlier age. A fairly common belief states that many pop stars die at the age of 27 years. This age has even been proclaimed as the most critical for modern musicians. However, data of several hundred deceased pop stars shows no evidence for increased mortality at the age of 27. Moreover, the data suggests that the age of death has increased over the past forty years. As far as the cause of death is concerned, overdose of drugs or alcohol rank highly next to cardiovascular disease and malignancy.

For legacy and emerging persistent organic pollutants (POPs), surprisingly little is still known in quantitative terms about their global sources and emissions. Atmospheric transport has been identified as the key global dispersal mechanism for most legacy POPs. In contrast, transport by ocean currents may prove to be the main transport route for many polar, emerging POPs. This is linked to the POPs' intrinsic physico-chemical properties, as exemplified by the different fate of hexachlorocyclohexanes in the Arctic. Similarly, our current understanding of POPs' global transport and fate remains sketchy. The importance of organic carbon and global temperature differences have been accepted as key drivers of POPs' global distribution. However, future research will need to understand the various biogeochemical and geophysical cycles under anthropogenic pressures to be able to understand and predict the global fate of POPs accurately. - Future studies into the global fate of POPs will need to pay more attention to the various biogeochemical and anthropogenic cycles to better understand emissions, transport and sinks

K-pop Reception and Participatory Fan Culture in Austria

Directory of Open Access Journals (Sweden)

Sang-Yeon Sung

2013-12-01

Full Text Available K-pop’s popularity and its participatory fan culture have expanded beyond Asia and become significant in Europe in the past few years. After South Korean pop singer Psy’s “Gangnam Style” music video topped the Austrian chart in October 2012, the number and size of K-pop events in Austria sharply increased, with fans organizing various participatory events, including K-pop auditions, dance festivals, club meetings, quiz competitions, dance workshops, and smaller fan-culture gatherings. In the private sector, longtime fans have transitioned from participants to providers, and in the public sector, from observers to sponsors. Through in-depth interviews with event organizers, sponsors, and fans, this article offers an ethnographic study of the reception of K-pop in Europe that takes into consideration local interactions between fans and Korean sponsors, perspectives on the genre, patterns of social integration, and histories. As a case study, this research stresses the local situatedness of K-pop fan culture by arguing that local private and public sponsors and fans make the reception of K-pop different in each locality. By exploring local scenes of K-pop reception and fan culture, the article demonstrates the rapidly growing consumption of K-pop among Europeans and stresses multidirectional understandings of globalization.

Temporary threshold shift after exposure to pop music.

Science.gov (United States)

Axelsson, A; Lindgren, F

1978-01-01

Temporary threshold shift (TTS) was studied in pop musicians as well as in listeners. It appears that TTS is less pronounced in pop musicians than in listeners. This can only in part be explained by slightly inferior hearing threshold levels than in the audience before exposure. Further, male listeners showed more TTS than female listeners. After 2 hours of exposure to live pop music a TTS2 appears in pop musicians after an exposure to 98 dB(A) as opposed to listeners where TTS2 appears at 92 dB(A). When the present results are related to the CHABA risk criteria it seems that exposure to live pop music at 100 dB(A) for 2 hours is a limit which should not be exceeded if the risk of permanent hearing loss is to be avoided.

Specific binding of a Pop6/Pop7 heterodimer to the P3 stem of the yeast RNase MRP and RNase P RNAs.

Science.gov (United States)

Perederina, Anna; Esakova, Olga; Koc, Hasan; Schmitt, Mark E; Krasilnikov, Andrey S

2007-10-01

Pop6 and Pop7 are protein subunits of Saccharomyces cerevisiae RNase MRP and RNase P. Here we show that bacterially expressed Pop6 and Pop7 form a soluble heterodimer that binds the RNA components of both RNase MRP and RNase P. Footprint analysis of the interaction between the Pop6/7 heterodimer and the RNase MRP RNA, combined with gel mobility assays, demonstrates that the Pop6/7 complex binds to a conserved region of the P3 domain. Binding of these proteins to the MRP RNA leads to local rearrangement in the structure of the P3 loop and suggests that direct interaction of the Pop6/7 complex with the P3 domain of the RNA components of RNases MRP and P may mediate binding of other protein components. These results suggest a role for a key element in the RNase MRP and RNase P RNAs in protein binding, and demonstrate the feasibility of directly studying RNA-protein interactions in the eukaryotic RNases MRP and P complexes.

Climate change and environmental concentrations of POPs: A review

Nadal, Martí; Marquès, Montse; Mari, Montse; Domingo, José L.

2015-01-01

In recent years, the climate change impact on the concentrations of persistent organic pollutants (POPs) has become a topic of notable concern. Changes in environmental conditions such as the increase of the average temperature, or the UV-B radiation, are likely to influence the fate and behavior of POPs, ultimately affecting human exposure. The state of the art of the impact of climate change on environmental concentrations of POPs, as well as on human health risks, is here reviewed. Research gaps are also identified, while future studies are suggested. Climate change and POPs are a hot issue, for which wide attention should be paid not only by scientists, but also and mainly by policy makers. Most studies reported in the scientific literature are focused on legacy POPs, mainly polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs) and pesticides. However, the number of investigations aimed at estimating the impact of climate change on the environmental levels of polycyclic aromatic hydrocarbons (PAHs) is scarce, despite of the fact that exposure to PAHs and photodegradation byproducts may result in adverse health effects. Furthermore, no data on emerging POPs are currently available in the scientific literature. In consequence, an intensification of studies to identify and mitigate the indirect effects of the climate change on POP fate is needed to minimize the human health impact. Furthermore, being this a global problem, interactions between climate change and POPs must be addressed from an international perspective.

PERSISTENT ORGANIC POLLUTANS (POPS DAN KONVENSI STOCKHOLM

Directory of Open Access Journals (Sweden)

Lina Warlina

2010-07-01

Full Text Available Persistent organic pollutants (POPs are toxic chemicals that adversely affect human health and the environment around the world. Because they can be transported by wind and water, most POPs generated in one country can affect people and wildlife far from where they are used and released. They persist for long periods of time in the environment and can accumulate and pass from one species to the next through the food chain. To address this global concern, many countries in the world joined forces with 90 other countries and the European Community to sign a groundbreaking United Nations treaty in Stockholm, Sweden, in May 2001, known as the Stockholm Convention. One of important agreement is all countries agreed to reduce or eliminate the production, use, and/or release of 12 key POPs. The Convention specifies a scientific review process that could lead to the addition of other POPs chemicals of global concern. POPs include a range of substances that include intentionally produced chemicals currently or once used in agriculture, disease control, manufacturing, or industrial processes. Also it can be produced by unintentionally produced chemicals, such as dioxins, that result from some industrial processes and from combustion (for example, municipal and medical waste incineration and backyard burning of trash.

Despite the importance of beans as food, few studies are conducted to control their contamination by persistent organic pollutants (POPs), compounds of great importance because of their toxicity and tendency to accumulate in food chains. In order to evaluate the human exposure to POPs by the consumption of beans a monitoring programme was conducted on polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) residues in samples coming from Italy, Mexico, India, Japan, Ghana and Ivory Coast. All beans were extracted with an accelerated solvents extractor in triplicate; the clean-up step was done with a Florisil column; identification and quantification was carried out using a TSQ Quantum XLS Ultra GC-MS/MS in selected reaction monitoring mode. Results revealed concentrations of ∑PAHs ranged from 7.31 µg kg -1 to 686 µg kg -1 , ∑PCBs between 1.85 µg kg -1 and 43.1 µg kg -1 and ∑OCPs ranged from 1.37 µg kg -1 to 71.8 µg kg -1 . Our results showed that beans coming from Ivory Coast are the most exposed to the risk of contamination by all the pollutants investigated. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Although various computer tools have been elaborately developed to calculate a series of statistics in molecular population genetics for both small- and large-scale DNA data, there is no efficient and easy-to-use toolkit available yet for exclusively focusing on the steps of mathematical calculation. Here, we present PopSc, a bioinformatic toolkit for calculating 45 basic statistics in molecular population genetics, which could be categorized into three classes, including (i) genetic diversity of DNA sequences, (ii) statistical tests for neutral evolution, and (iii) measures of genetic differentiation among populations. In contrast to the existing computer tools, PopSc was designed to directly accept the intermediate metadata, such as allele frequencies, rather than the raw DNA sequences or genotyping results. PopSc is first implemented as the web-based calculator with user-friendly interface, which greatly facilitates the teaching of population genetics in class and also promotes the convenient and straightforward calculation of statistics in research. Additionally, we also provide the Python library and R package of PopSc, which can be flexibly integrated into other advanced bioinformatic packages of population genetics analysis.

Terrestrial mosses as biomonitors of atmospheric POPs pollution: A review

International Nuclear Information System (INIS)

Harmens, H.; Foan, L.; Simon, V.; Mills, G.

2013-01-01

Worldwide there is concern about the continuing release of persistent organic pollutants (POPs) into the environment. In this study we review the application of mosses as biomonitors of atmospheric deposition of POPs. Examples in the literature show that mosses are suitable organisms to monitor spatial patterns and temporal trends of atmospheric concentrations or deposition of POPs. These examples include polycyclic aromatic hydrocarbons (PAHs), polychlorobiphenyls (PCBs), dioxins and furans (PCDD/Fs), and polybrominated diphenyl ethers (PBDEs). The majority of studies report on PAHs concentrations in mosses and relative few studies have been conducted on other POPs. So far, many studies have focused on spatial patterns around pollution sources or the concentration in mosses in remote areas such as the polar regions, as an indication of long-range transport of POPs. Very few studies have determined temporal trends or have directly related the concentrations in mosses with measured atmospheric concentrations and/or deposition fluxes. - Highlights: ► Terrestrial mosses are suitable organisms to monitor deposition of POPs. ► They provide a good indication of spatial patterns and temporal trends. ► Mosses have been used as biomonitors of PAHs, PCBs, PBDEs dioxins and furans. ► Few studies have assessed the relationship between concentrations in air and mosses. - Mosses are suitable biomonitors of persistent organic pollutants (POPs).

Full Text Available Television, music videos, films, and pop bands are all part of global popular culture and thought to be the product of “the west”. These media are therefore often seen as a threat to the identities of nationalities, local cultures, and religious groups. In contrast, in the context of Indonesian Muslims, the Indonesian Ulama Council’s (Majelis Ulama Indonesia, MUI showed support for Fatin Shidqia Lubis to the singing contest of Indonesian X Factor, 2013. This paper intends to study the presence of Fatin Sidqiah as the winner of Indonesian X Factor and the response of Indonesian muslims regarding Islamic popular culture in Indonesia. This paper argues that the presence of Islamic popular culture in Indonesia through books, novels, films, as well as fashion, show that Indonesian Islam and muslims are compatible not only with democracy but also with global popular culture. In addition, the presence of Fatin is a symbol of young Indonesian muslims who already connect globally. Whatever they consume in terms of popular culture is intrinsic to the creation of their hybrid identities, as both Indonesian muslims and global citizens.[Televisi, musik, film, dan bands merupakan bagian dari budaya popular dunia dan selalu dipandang sebagai produk “barat”. Karenanya, media ini sering dianggap sebagai ancaman bagi identitas nasional, budaya lokal, dan kelompok agama. Namun, dalam konteks keindonesiaan, Majelis Ulama Indonesia (MUI memberikan dukungan kepada Fatin Sidqia Lubis dalam kompetisi menyanyi “Indonesian X Factor” Tahun 2013. Tulisan ini mencoba menelisik kemunculan Fatin sebagai pemenang “Indonesian X Factor” dan tanggapan masyarakat mengenai budaya pop Islam di Indonesia. Melalui artikel ini penulis berpendapat bahwa kehadiran budaya pop di Indonesia dalam berbagai buku, novel, film, serta pakaian menunjukkan bahwa Islam dan masyarakat Islam di Indonesia tidak hanya sejalan dengan demokrasi, tetapi juga dengan budaya pop dunia

The aim of this study was to present the development, structure and results of a database on planned and ongoing health technology assessment (HTA) projects (POP Database) in Europe. The POP Database (POP DB) was set up in an iterative process from a basic Excel sheet to a multifunctional electronic online database. The functionalities, such as the search terminology, the procedures to fill and update the database, the access rules to enter the database, as well as the maintenance roles, were defined in a multistep participatory feedback loop with EUnetHTA Partners. The POP Database has become an online database that hosts not only the titles and MeSH categorizations, but also some basic information on status and contact details about the listed projects of EUnetHTA Partners. Currently, it stores more than 1,200 planned, ongoing or recently published projects of forty-three EUnetHTA Partners from twenty-four countries. Because the POP Database aims to facilitate collaboration, it also provides a matching system to assist in identifying similar projects. Overall, more than 10 percent of the projects in the database are identical both in terms of pathology (indication or disease) and technology (drug, medical device, intervention). In addition, approximately 30 percent of the projects are similar, meaning that they have at least some overlap in content. Although the POP DB is successful concerning regular updates of most national HTA agencies within EUnetHTA, little is known about its actual effects on collaborations in Europe. Moreover, many non-nationally nominated HTA producing agencies neither have access to the POP DB nor can share their projects.

Fan activism, cybervigilantism, and Othering mechanisms in K-pop fandom

Directory of Open Access Journals (Sweden)

Sun Jung

2012-06-01

Full Text Available Korean popular music (K-pop fandom may serve as a case study to identify both cynical and utopian views of fans' participatory Net activism by addressing three key aspects: fan activism, cybervigilantism, and Othering mechanisms. Fancom (fan company in the K-pop scene refers to the way fans systematically manage their own stars. These notions of assertive fancom practices address how fans actively participate in sociocultural events such as fund raising, donating to charity, and volunteering in emergency situations. This management may take another turn, however: antifandom surrounds K-pop star Tablo, signifying cybervigilantism of sinsang teolgi (personal information theft, a term referring to the online activities of a group of netizens who seek to expose the personal details of perceived wrongdoers by publishing them online as a form of punishment. The Tablo case revitalized public concern over privacy and the security of personal information in the digital era. Finally, Othering mechanisms in participatory online K-pop fandom display a strong sense of nationalism and even racism, as demonstrated by responses to anti-Korean rhetoric posted on the MySpace page of K-pop idol Jae-Beom. This highlights the relationship between participatory Net activism and nationalistic sentiment active within K-pop fandom. Some K-pop fan practices may have negative connotations, but by engaging with specific civic issues and social events, participatory fan practices encourage people to interact, discuss, and challenge conventional discourses, which may lead to new forms of social action.

Berejnoi C.

2000-01-01

Full Text Available The pop-in phenomenon, quite common in fracture mechanics tests of welded joints, corresponds to a brittle crack initiation grown from a local brittle zone (LBZ that is arrested in reaching the higher toughness material that surrounds this LBZ. A methodology to obtain a high percentage of pop-in occurrence in laboratory testing is necessary to study the pop-in significance. Such a method is introduced in this work and includes the consumable combination and welding procedures for the SMAW welding process to generate artificial LBZ. In order to find out the influence of the loading state upon the pop-in phenomenon, laboratory CTOD tests were performed using two specimen configurations: some single edge-notched specimens were loaded on a three-point bending (SE(B fixture while others were tested in tensile load (SE(T. A higher frequency of pop-in occurrence was observed in the SE(B geometry.

Full Text Available Writing, one of the four skills which has to be taught by educators in language learning. Starting from classroom observation implied that students confronted the difficulties in writing involving generating ideas, organizing words, and making compositions. This study supposes to explore some effects of pop culture as authentic materials for English language teaching in improving students‘ writing skill. Due to pop culture relates to students‘ life and experience, it is considered to be a stimulus for gaining students‘ ideas, information, motivation, and interest in teaching writing. The students of secondary school were involved in this study and descriptive case study was employed to observe the importance of pop culture in writing class. Also, questionnaires and students‘ works are the instruments to measure its effects. Both students‘ works and result of the questionnaires pointed out that significantly improvement obtained after applying pop culture. In line with findings, it can be said that pop cultures have significant effects toward students‘ writing skill. So, educators need to apply pop culture as their choices in future planning lesson.

Popping Rocks Revealed: Investigations from 14°N on the Mid-Atlantic Ridge

The popping rock, recovered in dredge 2πD43 in 1985, is commonly considered to be one of the most representative samples of undegassed upper mantle, based on high volatile and noble gas abundances. While this basalt is used to reconstruct mantle volatile contents and CO2 fluxes from mid-ocean ridges (MOR), the origin of the popping rock has remained ambiguous due to a lack of geologic context. Here, we present results from the first combined geochemical, geophysical, and geologic investigation of popping rocks from 14N on the Mid-Atlantic Ridge. By combining lava compositions with high-resolution bathymetric maps, we show that the popping rocks are confined to a single geographic area, at the transition between magmatic and tectonic segments. Fifteen popping rocks were collected in situ using the Alvin submersible in 2016. X-ray microtomography indicates that these lavas have variable vesicle abundances; including the highest vesicularities (>19%) recorded for any MOR basalt. Dissolved CO2 contents (163-175 ppm) are similar to proximal non-popping rocks and are in equilibrium at their eruption depths (>3600 m); however, total CO2 contents (based on vesicularity, dissolved CO2, and vesicle gas contents) are higher than non-popping rocks, ranging from 2800-14150 ppm. The popping rocks have average 3He/4He ratios of 8.17 ± 0.1 Ra and 4He concentrations of 1.84e-5 to 7.67e-5 cc/g STP. Compared to non-popping lavas, the popping rocks have a narrow range of major and trace element concentrations, suggesting little to no crystallization occurred during ascent or eruption. REE patterns and trace element ratios are indistinguishable in the popping rocks (La/Sm = 2.89 ± 0.05), indicating similar mantle sources and extents of melting. Based on lava compositions and spatial distribution, we suggest that the popping rocks at 14N were produced under similar magmatic conditions and erupted over short timescales, perhaps during a series of closely timed eruptions.

In Article 16 of Stockholm Convention for the global elimination of Persistent Organic Pollutants (POPs), it is written that ''comparable monitoring data'' reported by the Parties will be used for the ''effectiveness evaluation of the Convention''. A detailed evaluation scheme will be decided by the Conference of the Parties, but various technical aspects of this POPs monitoring were discussed by the international experts at UNEP Chemical's workshop on the development of Global POPs Monitoring held in Geneva in March 2003, and the guidance documents for the monitoring are now being prepared based on the results of the workshop. The Ministry of the Environment (MoE), Japan, has been conducting environmental monitoring of various pollutants including major POPs in Japan for more than two decades, and reported the results every year in a report ''Chemicals in the Environment'' (or KUROHON, meaning ''black book'' in Japanese). Originally a conventional GC/ECD method had been employed for the analysis of organochlorine chemicals (OCs) in biological samples. Then a GC/MS (low resolution) was introduced for OCs analysis in sediments and water, and GC/high resolution(HR)-MS method was introduced for dioxins analysis from around 1990. Due to general decline of POPs levels in the environment, the number of ND (not detected = less than detection limits) data had been increasing in recent years, and consequently it became difficult to extract temporal trends from the monitoring data. In 2002, MoE decided to reorganize the environmental monitoring framework in order to respond to the request of POPs convention, and re-started POPs monitoring by using more sensitive GC/HR-MS method for the analysis of nine POPs chemicals (dioxins and furans have already been monitored by the method; toxaphene is analyzed by GC/negative ionization-MS). The primary purpose of this reorganization is to reveal

2016-01-01

The expanded availability of electronic health information has led to increased interest in distributed health data research networks. The distributed research network model leaves data with and under the control of the data holder. Data holders, network coordinating centers, and researchers have distinct needs and challenges within this model. The concerns of network stakeholders are addressed in the design and governance models of the PopMedNet software platform. PopMedNet features include distributed querying, customizable workflows, and auditing and search capabilities. Its flexible role-based access control system enables the enforcement of varying governance policies. Four case studies describe how PopMedNet is used to enforce network governance models. Trust is an essential component of a distributed research network and must be built before data partners may be willing to participate further. The complexity of the PopMedNet system must be managed as networks grow and new data, analytic methods, and querying approaches are developed. The PopMedNet software platform supports a variety of network structures, governance models, and research activities through customizable features designed to meet the needs of network stakeholders.

Spectral distribution of solo voice and accompaniment in pop music.

Science.gov (United States)

Borch, Daniel Zangger; Sundberg, Johan

2002-01-01

Singers performing in popular styles of music mostly rely on feedback provided by monitor loudspeakers on the stage. The highest sound level that these loudspeakers can provide without feedback noise is often too low to be heard over the ambient sound level on the stage. Long-term-average spectra of some orchestral accompaniments typically used in pop music are compared with those of classical symphonic orchestras. In loud pop accompaniment the sound level difference between 0.5 and 2.5 kHz is similar to that of a Wagner orchestra. Long-term-average spectra of pop singers' voices showed no signs of a singer's formant but a peak near 3.5 kHz. It is suggested that pop singers' difficulties to hear their own voices may be reduced if the frequency range 3-4 kHz is boosted in the monitor sound.

From Antagonism to Cooperation: Pop-Culture as Reflected in Protestant Theology

Directory of Open Access Journals (Sweden)

Olga Mikhelson

2014-02-01

Full Text Available The author examines how theologians, especially Protestants, have changed their attitude to pop-culture. A veritable evolution has taken place. At one time, Protestant theologians refused to even acknowledge the existence of the phenomenon, while today some of these theologians employ examples drawn from pop-culture even in their lessons of theology. The author studies this contemporary development and offers some reasons for why it has come about. One ofthese theologians, a certain Gordon Lynch, has become a convinced apologist for pop-culture and analyses it on the basis of his threefold theory of the levels of the functionality of religion: sociological, existential (hermeneutic, and transcendental. In Lynch’s opinion, pop-culture has taken over the role of religion in many cases. He cites the popular cartoon The Simpsons as one prominent example. Religion plays an important part in this cartoon series and Protestant theologians have begun to take notice an opposite change of attitude towards religion in pop-culture, viewing the development in a positive way. Though pop-cultural products may be used in pastoral ministry and are also being evaluated by theologians, this analysis cannot be called scientific in the strictest sense, since generally it remains within the scope of only theological approach.

2010-05-01

The aim to prepare and present this paper is to highlight the source, management and quantification of the unintentional POPs in an unindustrialized least developing landlocked small country Nepal. The methodology adopted for this is the review of the relevant research documents and national initiative towards addressing this issues complemented with sharing of the first hand experience from the implementation of the POPs management activities undertaken by our organization. Nepal is a small country of size 147181 sq.km but having large sources of POPs including unintentional POPs (PCDD/Fs) mainly because of weak enforcement of the existing environment related laws, standards and international commitment including POPs Convention. Country became homes to about 75 tons of Obsolete Pesticide since last 30 years including about 44 percent (33 tons out of 75) are of known POPs. These obsolete pesticides including identified POPs have been poorly stored in some about 25 locations throughout the country. The major warehouse accommodating about 50 tons at Amlekhgunj has been located just in front of a high school where about 1000 children are being studying and found to have some health related problem due to the gasses emission from the warehouse as well as school playground field contaminated with these POPs pesticides. The playground soil contamination has been found from routine examination of the soil samples. In addition to pesticides including POPs were used in the agriculture and public health field in the past, there are several other practices as well as anthropogenic activities producing PCDD/Fs. The annual inventory of countrywide emission of unintentional POPs was estimated to be 312.55 g TEQ for Nepal (MOE 2004). This is very high for a country like Nepal least developing in terms of industrial and economy. This estimation was based on the UNEP Toolkit which has included the broad categories of waste such as waste incineration, ferrous and non ferrous metal

Recent evolution of the NF-κB and inflammasome regulating protein POP2 in primates

Directory of Open Access Journals (Sweden)

Harton Jonathan A

2011-03-01

Full Text Available Abstract Background Pyrin-only protein 2 (POP2 is a small human protein comprised solely of a pyrin domain that inhibits NF-κB p65/RelA and blocks the formation of functional IL-1β processing inflammasomes. Pyrin proteins are abundant in mammals and several, like POP2, have been linked to activation or regulation of inflammatory processes. Because POP2 knockout mice would help probe the biological role of inflammatory regulation, we thus considered whether POP2 is common in the mammalian lineage. Results BLAST searches revealed that POP2 is absent from the available genomes of not only mice and rats, but those of other domestic mammals and New World monkeys as well. POP2 is however present in the genome of the primate species most closely related to humans including Pan troglodytes (chimpanzees, Macaca mulatta (rhesus macaques and others. Interestingly, chimpanzee POP2 is identical to human POP2 (huPOP2 at both the DNA and protein level. Macaque POP2 (mqPOP2, although highly conserved is not identical to the human sequence; however, both functions of the human protein are retained. Further, POP2 appears to have arisen in the mammalian genome relatively recently (~25 mya and likely derived from retrogene insertion of NLRP2. Conclusion Our findings support the hypothesis that the NLR loci of mammals, encoding proteins involved in innate and adaptive immunity as well as mammalian development, have been subject to recent and strong selective pressures. Since POP2 is capable of regulating signaling events and processes linked to innate immunity and inflammation, its presence in the genomes of hominids and Old World primates further suggests that additional regulation of these signals is important in these species.

The proximate chemical composition of the three tested sorghum varieties during the stages of processing to pop the poly phenols (phytic acid and tannins) beside starch and some minerals (the macro elements potassium, calcium and the microelements, iron and zinc) were determined. The range of chemical composition of raw sorghum varieties were as follows: moisture 8.57-9.13%; ash 1.51-2.16%; crude fat 3.39-3.62%; protein 9.06-18.58%; carbohydrates 67.41-76.58; starch 65.23-74.66; tannins 0.3.3-0.28 mg/100 g; phytic acid 2.90-4.93 mg/100 g; iron 3.43-4.58 mg/100 g; calcium 5.17-11.26 mg/100 g; zinc 1.48-2.78 mg/100 g; potassium 198.80-387.78 mg/100 g. The results showed significant difference between the three sorghum varieties. The chemical composition of the boiled stage were: moisture 11.80-13.06%; ash 1.49-2.12 %; crude fat 3.63-3.79%; crude protein 10.32-18.50%; carbohydrate 62.86-71.68; starch 64.14-74.10; tannin 0.12-0.18 mg/100 g; phytic acid 2.39-3.69 mg/100 g; iron 4.44-5.45 mg/100g; calcium 9.26-20.19 mg/100g; zinc 1.33-2.43 mg/100g; potassium 184.62-266.08 mg/100g. The chemical composition of pop sorghum products gave: moisture 3.66-4.93%; ash 1.49-2.35%, crude fat 3.61-3.91%; crude protein 9.13-15.82%; carbohydrates 74.56-81.06%; starch 70.14-77.58%; tannins 0.29-0.34 mg/100g; phytic acid 0.93-2.23 mg/100g; iron 3.65-79 mg/100g; calcium 18.72-23.09 mg/100g; zinc 1.45-2.48 mg/100g; potassium 190.53-322.44 mg/100g.

2013-12-01

Full Text Available This study examines the role that fan communities in Israel and Palestine play in the transcultural dissemination of Korean popular music, or “K-pop.” Based on in-depth interviews with fans, a survey of K-pop online communities, discourse analysis of online discussions, and participation in K-pop gatherings, this article examines the practice of K-pop, its localization and institutionalization, and its influence on the identities of fans. Special attention is given to the role of K-pop fans as cultural mediators who create necessary bridges between the music industry and local consumers and thus play a decisive role in globalizing cultures. Typically, literature on the globalization of popular culture either utilizes a top-down approach, depicting powerful media industries as making people across the world consume their products, or emphasizes a bottom-up resistance to the imposition of foreign cultures and values. This article suggests that popular culture consumption not only changes the lives of a few individuals but that these individuals may themselves play a decisive role in connecting globalized culture with local fandom.

Resistance to Western Popular and Pop-Culture in India

Algis Mickūnas

2017-03-01

Full Text Available The essay is designed to present the phenomena of popular culture, its difference from pop culture, both products of modern West, and their impact on film and advertisement media in India. First, the discussion focuses on the Critical School which proposed the initial thesis of commodification of culture with a resultant “lowering” of standards to appeal to “the masses”, and an appeal to the “average” tastes. In the essay an argument is presented that pop culture is a “critique” of popular culture and is an elitist position attempting to shock popular mores and media content. Given this setting, it is argued that while India has followed both the globalizing popular and pop cultures, neither are adequate to encompass Indian media, specifically their film content.

Lifetime achievement awards are awarded to recognize contributions during the career of an individual, rather than for a single or multiple contributions of a person in his/her field of specialty. I am highly honored being the recipient of the Dr. K. C. Chaudhuri Lifetime Achiement Award Oration. The award for me is significant for several reasons: First being associated with legendary figure such as Dr. Chaudhuri, secondly being recognized by my fellow Indian colleagues. Finally, it also marks half a century of my experience in development of subspecialty of neonatology in US. Some fifty and odd years ago, as an young novice from India I joined the mainstream of this evolution, thanks to my professors and mentors in US and thanks to America, the land of opportunity. During this odyssey, I met many great men and women of science and intellect, saw great scientific discoveries, many innovations, combined with social changes that led to significant reduction of neonatal mortality rates in the industrialized Western countries. I also saw the "Globalization" of "Modern Neonatology" in which I participated with vigor; thus, improving the newborn care in four corners of the world. I am proud that I had the opportunity to contribute a little to growth of neonatology in US and outside the US. This is the story of my professional life. The message of my life story for the younger generation is : Dream big, never give up your dreams. Hardwork, maintaining your integrity, and honesty are the three precepts that will define your character and you will be rewarded in the long run.

OBJECTIVES: Progestogen-only pills (POPs) are safer with respect to cardiovascular risks than contraceptives containing estrogens. Despite the increased contraceptive efficacy of a desogestrel-only pill compared with a traditional POP, POPs are still not widely used due to an unpredictable bleeding...... pattern. A new POP containing 4 mg drospirenone has been developed with a 24/4 intake regimen which may improve the bleeding pattern. The objectives of this study were to investigate ovulation inhibition with the new drospirenone-only pill in comparison with the desogestrel-only pill and, in addition......, to assess the effects on cervical mucus permeability and bleeding. METHODS: Sixty-four healthy volunteers with proven ovulatory cycles were randomised and treated with either the drospirenone-only or the desogestrel-only pill during two 28-day cycles.

Full Text Available Article discusses the domination of Malay pop music through textual analysis of songs, observation of musical programs, and interviews with important figures. The research data were obtained by library research and analyzed through a critical theory approach to gain an understanding of the text and its effects. The article concludes that Malay pop contains a strong uniformity which may be termed a phenomenon in the context of the culture industry, while also being dominant because of its legitimacy created by the media. The nature of Malay pop is also very profitable for those participating in it, therefore the spirit of capitalism was also quite dominant in this context. There is also resistance from the indie music movement, and its attempts to fight regressive qualities of music that are legitimized in the mainstream mass media.  

Ways to suppress click and pop for class D amplifiers

Undesirable audio click and pop may be generated in a speaker or headphone. Compared to linear (class A/B/AB) amplifiers, class D amplifiers that comprise of an input stage and a modulation stage are more prone to producing click and pop. This article analyzes sources that generate click and pop in class D amplifiers, and corresponding ways to suppress them. For a class D amplifier with a single-ended input, click and pop is likely to be due to two factors. One is from a voltage difference (V DIF ) between the voltage of an input capacitance (V CIN ) and a reference voltage (V REF ) of the input stage, and the other one is from the non-linear switching during the setting up of the bias and feedback voltages/currents (BFVC) of the modulation stage. In this article, a fast charging loop is introduced into the input stage to charge V CIN to roughly near V REF . Then a correction loop further charges or discharges V CIN , substantially equalizing it with V REF . Dummy switches are introduced into the modulation stage to provide switching signals for setting up BFVC, and the power switches are disabled until the BFVC are set up successfully. A two channel single-ended class D amplifier with the above features is fabricated with 0.5 μm Bi-CMOS process. Road test and fast Fourier transform analysis indicate that there is no noticeable click and pop. (semiconductor integrated circuits)

Full Text Available A study on the utilization of black  tiger shrimp (Penaeus monodon flesh waste in the processing of pop shrimp has been carried out.  So far, shrimp flesh waste is used for the production of shrimp paste, and shrimp cracker.   The objective of this study was to develop a fomula for pop shrimp production using shrimp flesh waste. Experimental design applied in this study was three-variables mixture design, in which variables observed were shrimp flesh waste, surimi and tapioca flour. Pop shrimp obtained was evaluated for sensory properties. The best product processed using a selected formula was analysed chemically and microbiologically, particularly for proxymate composition and total plate count respectively. Selected formula of pop shrimp consisted of 50.91% shrimp flesh waste, 18.18% surimi, 3.64% tapioca flour, 10.91% onion, 2.18% garlic, 0.73% pepper powder, 1.45% sugar, 0.36% monosodium glutamate, 0.73% ginger, 1.45% salt, 4.44% butter mix, 1.38% corn flour (maizena and 3.64% bread crumb. Proxymate composition of the best pop shrimp was 70.52% moisture, 0.73% ash, 0.39% fat, and 7.44% protein, while microbiological load in terms of total plate count was 3.3x103 colonies/g.

Failure to pop out: Feature singletons do not capture attention under low signal-to-noise ratio conditions.

Pop-out search implies that the target is always the first item selected, no matter how many distractors are presented. However, increasing evidence indicates that search is not entirely independent of display density even for pop-out targets: search is slower with sparse (few distractors) than with dense displays (many distractors). Despite its significance, the cause of this anomaly remains unclear. We investigated several mechanisms that could slow down search for pop-out targets. Consistent with the assumption that pop-out targets frequently fail to pop out in sparse displays, we observed greater variability of search duration for sparse displays relative to dense. Computational modeling of the response time distributions also supported the view that pop-out targets fail to pop out in sparse displays. Our findings strongly question the classical assumption that early processing of pop-out targets is independent of the distractors. Rather, the density of distractors critically influences whether or not a stimulus pops out. These results call for new, more reliable measures of pop-out search and potentially a reinterpretation of studies that used relatively sparse displays.

Beluga populations in the St. Lawrence Estuary (SLE) are now threatened. The decline of the beluga population has been attributed to the presence of high concentrations of persistent organic pollutants (POPs). This study assessed the temporal trends of POPs in beluga, including polychlorinated biphenyls (PCBs), DDT, chlordanes, halogenated cyclic hydrocarbon (HCH) isomers, halogenated cyclic hydrocarbons (HCB), and mirex in SLE populations between 1987 and 2002. Blubber concentrations of individual POP or POP groups in both male and female belugas were fitted to simple natural algorithms using linear regression analyses. Only animals older than 10 years were examined. POPs, PCBs, and organochlorine pesticides (OCPs) were determined in blubber samples. Temporal trends of biological parameters such as age, lipid content, and length of the animals were assessed separately for both female and male belugas. POP concentrations were expressed on a lipid weight basis for the statistical analyses. Temporal trends of biological parameters, individual POP or POP group concentrations in both females and males were assessed using simple in-linear regression analysis from which half-life time was calculated for each statistically significant time trend. Results showed that approximately half of the POPs showed significant decreasing levels in female beluga between 1987 and 2002 and in males between 1988 and 2002. Temporal trends of PCBs, DDTs, and HCH were significant in both males and females, while chlordanes, and mirex levels were not significant in either sex. HCB exhibited a significant time trend in males. Time trends were in agreement with expected declines for regulated POPs. It was concluded that bioaccumulative POPs must be rapidly regulated before they reach high levels, as POP compounds are very slowly eliminated by belugas. 9 refs., 1 tab.

WHAT POPS OUT IN POSITIONAL PRIMING OF POP-OUT: INSIGHTS FROM EVENT-RELATED EEG LATERALIZATIONS

Directory of Open Access Journals (Sweden)

Ahu eGokce

2014-07-01

Full Text Available It is well established that, in visual pop-out search, reaction time (RT performance is influenced by cross-trial repetitions versus changes of target-defining attributes. One instance of this is referred to as ‘positional priming of pop-out (pPoP’ (Maljkovic & Nakayama, 1996. In positional PoP paradigms, the processing of the current target is examined depending on whether it occurs at the previous target or a previous distractor location, relative to a previously empty location (‘neutral’ baseline, permitting target facilitation and distractor inhibition to be dissociated. The present study combined RT measures with specific sensory- and motor-driven event-related lateralizations to track the time course of four distinct processing levels as a function of the target’s position across consecutive trials. The results showed that, relative to targets at previous target and ‘neutral’ locations, the appearance of a target at a previous distractor location was associated with a delayed build-up of the PCN wave, indicating that distractor positions are suppressed at early stages of visual processing. By contrast, presentation of a target at a previous target, relative to ‘neutral’ and distractor locations, modulated the elicitation of the subsequent sLRP wave, indicating that post-selective response selection is facilitated if the target occurred at the same position as on the previous trial. Overall, the results of present study provides electrophysiological evidence for the idea that target location priming (RT benefits does not originate from an enhanced coding of target saliency at repeated (target locations; instead, they arise (near- exclusively from processing levels subsequent to focal-attentional target selection.

Application of wMelPop Wolbachia Strain to Crash Local Populations of Aedes aegypti.

Directory of Open Access Journals (Sweden)

Scott A Ritchie

Full Text Available The endosymbiotic bacteria Wolbachia pipientis (wMel strain has been successfully established in several populations of Aedes aegypti, the primary dengue vector. The virulent Wolbachia strain wMelPop is known to cause several pathological impacts (increased egg mortality, life shortening, etc. reducing overall fitness in the mosquito Ae. aegypti. Increased egg mortality could substantially reduce egg banks in areas with a lengthy monsoonal dry season, and be employed to eliminate local populations. We tested this application under semi-field cage conditions. First, we determined that wMelPop infection significantly reduced the survival of desiccation-resistant eggs of the dengue vector Ae. aegypti, with shade and temperature having a significant impact; nearly all wMelPop-infected eggs failed to hatch after 6 and 10 weeks in summer and winter conditions, respectively. In laboratory selection experiments we found that egg desiccation resistance can be increased by selection, and that this effect of wMelPop infection is due to the nuclear background of the host rather than Wolbachia. We then conducted an invasion of wMelPop within a semi-field cage using sustained weekly releases of wMelPop infected mosquitoes, with fixation achieved after 9 weeks. The egg populations wMelPop infected and an uninfected control were then subjected to a simulated prolonged monsoonal dry season (2.5 months before flooding to induce hatching. The wMelPop infected eggs suffered significantly greater mortality than the controls, with only 0.67% and 4.35% of respective infected and uninfected eggs held in 99% shade hatching after 80 days. These studies suggest that wMelPop could be used to locally eliminate populations of Ae. aegypti that are exposed to prolonged dry conditions, particularly if combined with vector control.

2016-12-01

In New Zealand a simple pop-up message feature that provides gambling session information and forces a break in play is mandatory on all electronic gaming machines in all venues (EGMs). Previous research has demonstrated small effects of more sophisticated pop-up messages tested predominantly in laboratory environments. The present research examined gambler engagement with and views on the New Zealand pop-up messages and on the relationship between pop-up messages and EGM expenditure. A sample of gamblers was recruited at casino and non-casino (pub) EGM venues. Most participants were aware of pop-up messages (57 %) and many saw them often (38 %). Among gamblers who reported seeing pop-up messages, half read the message content, and a quarter believed that pop-up messages helped them control the amount of money they spend on gambling. Participants who reported being likely to stop gambling in response to pop-up messages spent significantly less money on gambling when variables that were independently associated with EGM expenditure were controlled for. A modest harm minimisation effect of the pop-up message feature that has been operating in New Zealand for 5 years was evident. Suggestions for improvement of the harm minimisation potential of the current pop-up message feature are discussed.

Increased frequency of involuntary semantic memories or mind-pops in schizophrenia: a diary study.

Elua, Ia; Laws, Keith R; Kvavilashvili, Lia

2015-01-01

Hallucinations constitute a prominent symptom of schizophrenia and may take a variety of forms (verbal, visual, musical, or environmental noises). Interesting similarities exist between hallucinations and so-called mind-pops which refer to isolated fragments of one's semantic knowledge (e.g., a word/sentence, visual image, or a song/melody) that come to mind unexpectedly, often without any obvious triggers, and are difficult to control. The aim of the present study was to evaluate whether mind-pops may constitute the raw cognitive material from which hallucinations are constructed by studying the nature and frequency of mind-pops in the everyday life of people with schizophrenia and non-clinical controls. Eleven participants with schizophrenia and 14 non-clinical controls kept a diary of their mind-pops for seven days and completed a brief questionnaire every time they had a mind-pop. Schizophrenia participants reported significantly more verbal and image mind-pops than controls and their content was negative more often than in controls. No group differences were obtained in terms of reported triggers or ongoing activities. Data from both groups also supported the priming hypothesis by showing that stimuli encountered in one's environment or thoughts could later re-appear in the form of a mind-pop. The findings have implications for models of schizophrenia that emphasise the role of intrusive thoughts and memories in the aetiology and development of key psychotic symptoms.

Narrated Political Theory: Theorizing Pop Culture in Dietmar Dath’s Novel Für immer in Honig

Directory of Open Access Journals (Sweden)

Georg Spitaler

2013-12-01

Full Text Available In recent decades, debates on the relationship between pop culture and the political have transgressed academia and have even been prominent in pop (media discourses and texts, including pop literature. Amongst the contributions at the inter-section of art, theory and entertainment are the novels and essays by the German author Dietmar Dath. Taking the example of his novel Für immer in Honig (Berlin 2005/2008, it will be discussed how the book reloads and theorizes pop culture, and how a common cultural-theoretical narrative of de-politicized pop is challenged by the imaginative narratives of the novel. It will be argued that Dath’s references to affective ‘mattering maps’ of pop culture, that on the one hand tend to fall into the pitfalls of exclusive ‘pop sophis-tication’, nevertheless play a key role for his aesthetical/theoretical project of political emancipation, and that these references can be viewed as examples of why popular passions matter for the formation of political identities/subjectivities as well as for the production and reading of political theory.

Full Text Available Persistent organic pollutants (POPs, such as polychlorinated dibenzo-p-dioxins (PCDDs and dibenzofurans (PCDFs, polychlorinated biphenyls (PCBs, and polybrominated ethers (PBDEs, chloronaftalens (PCNs, and bisphenol A (BPA, are stable, lipophilic pollutants that affect fertility and cause serious reproductive problems, including ovotoxic action, lack of ovulation, premature ovarian failure (POF, or polycystic ovarian syndrome (PCOS. Most of the representatives of POPs influence the activation of transcription factors, not only activation of aromatic hydrocarbon receptor (AhR, but also the steroid hormone receptors. This minireview will focus on a variety of PAH activities in oocyte, ovary, placenta, and mammary gland. The complexity and diversity of factors belonging to POPs and disorders of the reproductive function of women indicate that the impact of environmental pollution as an important determinant factor in fertility should not be minimize.

The key issues remaining for the non-pesticide POPs are in part determined by their general source classification. For industrial chemicals, such as the polychlorinated biphenyls (PCBs), there is considerable uncertainty with respect to the relative importance of atmospheric emissions from various source categories. For PCBs, temperature is discussed as a potential key factor influencing atmospheric emission levels and patterns. When it comes to the unintentional by-products of combustion and industrial processes (PCDD/Fs), there is still a large uncertainty with respect to the relative contribution of emissions from unregulated sources such as backyard barrel burning that requires further consideration and characterisation. For hexachlorobenzene (HCB), the relative importance of primary and secondary atmospheric emissions in controlling current atmospheric concentrations remains one of the key uncertainties.

Lamon, L.; Dalla Valle, M.; Critto, A.; Marcomini, A.

2009-01-01

This paper presents a review on the implications of climate change on the monitoring, modelling and regulation of persistent organic pollutants (POPs). Current research gaps are also identified and discussed. Long-term data sets are essential to identify relationships between climate fluctuations and changes in chemical species distribution. Reconstructing the influence of climatic changes on POPs environmental behaviour is very challenging in some local studies, and some insights can be obtained by the few available dated sediment cores or by studying POPs response to inter-annual climate fluctuations. Knowledge gaps and future projections can be studied by developing and applying various modelling tools, identifying compounds susceptibility to climate change, local and global effects, orienting international policies. Long-term monitoring strategies and modelling exercises taking into account climate change should be considered when devising new regulatory plans in chemicals management. - Climate change implications on POPs are addressed here with special attention to monitoring, modelling and regulation issues.

The successful operation of a pop-up Langmuir probe system, which was installed in the JET MkIIa divertor, is described. The system utilises the ambient magnetic field in tokamak plasmas to act on a current carrying coil and pop up a rail containing Langmuir probes. Measurements were made using pin-plate probes which, owing to their relatively large exposed area, are ideally suited for use with such a system. Details of the design, testing, measurements and potential applications of JET's pop-up system are given. (orig.)

Full Text Available While attentional effects in visual selection tasks have traditionally been assigned "top-down" or "bottom-up" origins, more recently it has been proposed that there are three major factors affecting visual selection: (1 physical salience, (2 current goals and (3 selection history. Here, we look further into selection history by investigating Priming of Pop-out (POP and the Distractor Preview Effect (DPE, two inter-trial effects that demonstrate the influence of recent history on visual search performance. Using the Ratcliff diffusion model, we model observed saccadic selections from an oddball search experiment that included a mix of both POP and DPE conditions. We find that the Ratcliff diffusion model can effectively model the manner in which selection history affects current attentional control in visual inter-trial effects. The model evidence shows that bias regarding the current trial's most likely target color is the most critical parameter underlying the effect of selection history. Our results are consistent with the view that the 3-item color-oddball task used for POP and DPE experiments is best understood as an attentional decision making task.

Guidelines for biomonitoring persistent organic pollutants (POPs), using lichens and aquatic mosses – A review

International Nuclear Information System (INIS)

Augusto, Sofia; Máguas, Cristina; Branquinho, Cristina

2013-01-01

During the last decades, awareness regarding persistent organic pollutants (POPs), such dioxins and furans (PCDD/Fs) and polycyclic aromatic hydrocarbons (PAHs), has become a cutting-edge topic, due to their toxicity, bioaccumulation and persistency in the environment. Monitoring of PCDD/Fs and PAHs in air and water has proven to be insufficient to capture deposition and effects of these compounds in the biota. To overcome this limitation, environmental biomonitoring using lichens and aquatic mosses, have aroused as promising tools. The main aim of this work is to provide a review of: i) factors that influence the interception and accumulation of POPs by lichens; ii) how lichens and aquatic bryophytes can be used to track different pollution sources and; iii) how can these biomonitors contribute to environmental health studies. This review will allow designing a set of guidelines to be followed when using biomonitors to assess environmental POP pollution. -- Highlights: •We've reviewed the use of lichens and mosses as POP biomonitors. •We've discussed the factors that influence accumulation of POPs in lichens. •We've shown how biomonitors have been used to track pollution sources. •We've designed guidelines for the use of biomonitors to assess POP pollution. -- This review fulfils the lack of knowledge regarding the use of lichens and aquatic mosses as biomonitors of POPs, providing a set of guidelines to be followed

Full Text Available Over the last few years, there have been an increasing number of gaming operators that have incorporated on-screen pop-up messages while gamblers play on slot machines and/or online as one of a range of tools to help encourage responsible gambling. Coupled with this, there has also been an increase in empirical research into whether such pop-up messages are effective, particularly in laboratory settings. However, very few studies have been conducted on the utility of pop-up messages in real-world gambling settings. The present study investigated the effects of normative and self-appraisal feedback in a slot machine pop-up message compared to a simple (non-enhanced pop-up message. The study was conducted in a real-world gambling environment by comparing the behavioural tracking data of two representative random samples of 800,000 gambling sessions (i.e., 1.6 million sessions in total across two conditions (i.e., simple pop-up message versus an enhanced pop-up message. The results indicated that the additional normative and self-appraisal content doubled the number of gamblers who stopped playing after they received the enhanced pop-up message (1.39% compared to the simple pop-up message (0.67%. The data suggest that pop-up messages influence only a small number of gamblers to cease long playing sessions and that enhanced messages are slightly more effective in helping gamblers to stop playing in-session.

A Systems Biology Approach Reveals Converging Molecular Mechanisms that Link Different POPs to Common Metabolic Diseases.

Ruiz, Patricia; Perlina, Ally; Mumtaz, Moiz; Fowler, Bruce A

2016-07-01

A number of epidemiological studies have identified statistical associations between persistent organic pollutants (POPs) and metabolic diseases, but testable hypotheses regarding underlying molecular mechanisms to explain these linkages have not been published. We assessed the underlying mechanisms of POPs that have been associated with metabolic diseases; three well-known POPs [2,3,7,8-tetrachlorodibenzodioxin (TCDD), 2,2´,4,4´,5,5´-hexachlorobiphenyl (PCB 153), and 4,4´-dichlorodiphenyldichloroethylene (p,p´-DDE)] were studied. We used advanced database search tools to delineate testable hypotheses and to guide laboratory-based research studies into underlying mechanisms by which this POP mixture could produce or exacerbate metabolic diseases. For our searches, we used proprietary systems biology software (MetaCore™/MetaDrug™) to conduct advanced search queries for the underlying interactions database, followed by directional network construction to identify common mechanisms for these POPs within two or fewer interaction steps downstream of their primary targets. These common downstream pathways belong to various cytokine and chemokine families with experimentally well-documented causal associations with type 2 diabetes. Our systems biology approach allowed identification of converging pathways leading to activation of common downstream targets. To our knowledge, this is the first study to propose an integrated global set of step-by-step molecular mechanisms for a combination of three common POPs using a systems biology approach, which may link POP exposure to diseases. Experimental evaluation of the proposed pathways may lead to development of predictive biomarkers of the effects of POPs, which could translate into disease prevention and effective clinical treatment strategies.

Elevance of PCDD/PCDF formation for the evaluation of POPs destruction technologies - Necessity and current status

Energy Technology Data Exchange (ETDEWEB)

Weber, R. [Tuebingen Univ. (Germany)

2004-09-15

The Stockholm Convention on Persistent Organic Pollutants (POPs) states in Article 6 that POPs waste should be destroyed or disposed of in a way that the POPs content is destroyed or irreversibly transformed. In this context it is critical that the destruction methods used do not create by-products that are themselves POPs. Therefore one important criterion for assessment of a POPs destruction technology is the potential formation of POPs and other toxic by-products, in particular if higher toxic PCDDs/PCDFs are formed and under which operation conditions their formation is relevant (for the respective POPs destruction technology). A detailed evaluation of non-combustion technologies with respect to PCDD/PCDF formation is lacking to date. Most information with respect to PCDD/PCDF formation in non-combustion technologies in the present stage of evaluation is provided by the companies developing or selling the facility. In a laboratory study it was discovered that super critical water oxidation (SCWO), a technology listed from United Nations Environmental Programme UNEP as ''Commercialised Technology with Considerable Experience'' and from United Nations Industrial Development Organization (UNIDO) as ''Emerging and Innovative Technologies'', has the potential to form high concentrations of PCDFs (in the % range) during PCB destruction. Such elevated PCDF formations might occur even at temperatures of potential application. This highlights the necessity of a more rigorous assessment of non-combustion technologies with respect to their PCDD/PCDF formation potential and their actual applicability for PCB/POPs destruction. The present paper provides a critical impulse in this respect, discusses the relevant formation pathways with respect to POPs destruction technologies and proposes a basic framework on how evaluations may be performed.

A Management State of POPs (Persistent Organic Pollutants) and the Measuring Direction - Centered By-Products

Energy Technology Data Exchange (ETDEWEB)

Park, Jeong Gyu; Lee, Hee Seon [Korea Environment Institute, Seoul (Korea)

2000-12-01

The chemical materials, DDT and Dioxin, threaten the human health and take the high toxicity on ecosystem and a living thing. Because the chemical materials remain in environment for a long time due to a slow natural decomposition, they are biologically concentrated through the food cycle in ecosystem and have a characteristic to move a long distance. Owing to such toxicity and the characteristics of chemical materials, the world organization named them as Persistent Organic Pollutants (POPs) and has been actively progressing the international movement to strictly restrict them since the middle of 1990s. POPs regulation agreement, which is on progress centered in UNEP, is facing to the conclusion of the agreement of 2001 year. An agricultural chemical of organic chlorine among 12 POPs indicated by UNEP has been already prohibited in the domestic use and manufacturing or not registered, so the basic research, including search and monitoring if POPs remain or not, is required afterward. Because Dioxin, Puran, Hexachlorobenzene (HCB) among POPs, which are produced as by-products from all kinds of industrial processes, are not raw materials dislike other POPs, their use and manufacturing cannot be only prohibited by the related law but also they have few substitutes. Therefore, they should be applied by the different regulation from the existing toxic chemicals in order to manage the toxicity of the materials. However, the regulation on by-products among POPs is just in the beginning stage, and even the producing source has not been yet confirmed. This study suggests the necessity of the management on Dioxin, Puran, HCB, by-products among POPs, and presents the measuring direction with grasping the domestic and foreign trend of the regulation on the materials. 70 refs., 2 figs., 56 tabs.

Phytosterol oxidation products (POP) in foods with added phytosterols and estimation of their daily intake: A literature review.

Science.gov (United States)

Lin, Yuguang; Knol, Diny; Trautwein, Elke A

2016-10-01

1To evaluate the content of phytosterol oxidation products (POP) of foods with added phytosterols, in total 14 studies measuring POP contents of foods with added phytosterols were systematically reviewed. In non-heated or stored foods, POP contents were low, ranging from (medians) 0.03-3.6 mg/100 g with corresponding oxidation rates of phytosterols (ORP) of 0.03-0.06%. In fat-based foods with 8% of added free plant sterols (FPS), plant sterol esters (PSE) or plant stanol esters (PAE) pan-fried at 160-200°C for 5-10 min, median POP contents were 72.0, 38.1, and 4.9 mg/100 g, respectively, with a median ORP of 0.90, 0.48, and 0.06%. Hence resistance to thermal oxidation was in the order of PAE > PSE > FPS. POP formation was highest in enriched butter followed by margarine and rapeseed oil. In margarines with 7.5-10.5% added PSE oven-heated at 140-200°C for 5-30 min, median POP content was 0.3 mg/100 g. Further heating under same temperature conditions but for 60-120 min markedly increased POP formation to 384.3 mg/100 g. Estimated daily upper POP intake was 47.7 mg/d (equivalent to 0.69 mg/kg BW/d) for foods with added PSE and 78.3 mg/d (equivalent to 1.12 mg/kg BW/d) for foods with added FPS as calculated by multiplying the advised upper daily phytosterol intake of 3 g/d with the 90% quantile values of ORP. In conclusion, heating temperature and time, chemical form of phytosterols added and the food matrix are determinants of POP formation in foods with added phytosterols, leading to an increase in POP contents. Practical applications: Phytosterol oxidation products (POP) are formed in foods containing phytosterols especially when exposed to heat treatment. This review summarising POP contents in foods with added phytosterols in their free and esterified forms reveals that heating temperature and time, the chemical form of phytosterols added and the food matrix itself are determinants of POP formation with heating

Metal-poor star formation triggered by the feedback effects from Pop III stars

Chiaki, Gen; Susa, Hajime; Hirano, Shingo

2018-04-01

Metal enrichment by first-generation (Pop III) stars is the very first step of the matter cycle in structure formation and it is followed by the formation of extremely metal-poor (EMP) stars. To investigate the enrichment process by Pop III stars, we carry out a series of numerical simulations including the feedback effects of photoionization and supernovae (SNe) of Pop III stars with a range of masses of minihaloes (MHs), Mhalo, and Pop III stars, MPopIII. We find that the metal-rich ejecta reach neighbouring haloes and external enrichment (EE) occurs when the H II region expands before the SN explosion. The neighbouring haloes are only superficially enriched, and the metallicity of the clouds is [Fe/H] < -5. Otherwise, the SN ejecta fall back and recollapse to form an enriched cloud, i.e. an internal-enrichment (IE) process takes place. In the case where a Pop III star explodes as a core-collapse SN (CCSN), the MH undergoes IE, and the metallicity in the recollapsing region is -5 ≲ [Fe/H] ≲ -3 in most cases. We conclude that IE from a single CCSN can explain the formation of EMP stars. For pair-instability SNe (PISNe), EE takes place for all relevant mass ranges of MHs, consistent with the lack of observational signs of PISNe among EMP stars.

Cultural Studies Methodologies and Narrative Family Therapy: Therapeutic Conversations About Pop Culture.

Tilsen, Julie; Nylund, David

Therapists recognize that popular media culture is an influential force that shapes identities and relationships in contemporary society. Indeed, people have serious relationships with the commodities and practices that emerge from pop culture. However, they often lack the conceptual and conversational resources to engage meaningfully with clients about pop culture's influence in their lives. Cultural studies is introduced as an interdisciplinary approach that provides frameworks for both theory and practice that position therapists and clients to critically examine the role of pop culture in their lives. Cultural studies and narrative therapy are discussed as praxis allies that share a populist political intention and counter-hegemonic discursive practices. The integration of cultural studies methodologies into narrative therapy practice with a parent and her teenage daughter is illustrated through a case vignette. © 2016 Family Process Institute.

Structure of Pfu Pop5, an archaeal RNase P protein.

Science.gov (United States)

Wilson, Ross C; Bohlen, Christopher J; Foster, Mark P; Bell, Charles E

2006-01-24

We have used NMR spectroscopy and x-ray crystallography to determine the three-dimensional structure of PF1378 (Pfu Pop5), one of four protein subunits of archaeal RNase P that shares a homolog in the eukaryotic enzyme. RNase P is an essential and ubiquitous ribonucleoprotein enzyme required for maturation of tRNA. In bacteria, the enzyme's RNA subunit is responsible for cleaving the single-stranded 5' leader sequence of precursor tRNA molecules (pre-tRNA), whereas the protein subunit assists in substrate binding. Although in bacteria the RNase P holoenzyme consists of one large catalytic RNA and one small protein subunit, in archaea and eukarya the enzyme contains several (> or =4) protein subunits, each of which lacks sequence similarity to the bacterial protein. The functional role of the proteins is poorly understood, as is the increased complexity in comparison to the bacterial enzyme. Pfu Pop5 has been directly implicated in catalysis by the observation that it pairs with PF1914 (Pfu Rpp30) to functionally reconstitute the catalytic domain of the RNA subunit. The protein adopts an alpha-beta sandwich fold highly homologous to the single-stranded RNA binding RRM domain. Furthermore, the three-dimensional arrangement of Pfu Pop5's structural elements is remarkably similar to that of the bacterial protein subunit. NMR spectra have been used to map the interaction of Pop5 with Pfu Rpp30. The data presented permit tantalizing hypotheses regarding the role of this protein subunit shared by archaeal and eukaryotic RNase P.

Origamic architecture (OA) is a form of papercraft that involves cutting and folding a single sheet of paper to produce a 3D pop-up, and is commonly used to depict architectural structures. Because of the strict geometric and physical constraints, OA design requires considerable skill and effort. In this paper, we present a method to automatically generate an OA design that closely depicts an input 3D model. Our algorithm is guided by a novel set of geometric conditions to guarantee the foldability and stability of the generated pop-ups. The generality of the conditions allows our algorithm to generate valid pop-up structures that are previously not accounted for by other algorithms. Our method takes a novel image-domain approach to convert the input model to an OA design. It performs surface segmentation of the input model in the image domain, and carefully represents each surface with a set of parallel patches. Patches are then modified to make the entire structure foldable and stable. Visual and quantitative comparisons of results have shown our algorithm to be significantly better than the existing methods in the preservation of contours, surfaces, and volume. The designs have also been shown to more closely resemble those created by real artists.

Our algorithm is guided by a novel set of geometric conditions to guarantee the foldability and stability of the generated pop-ups. The generality of the conditions allows our algorithm to generate valid pop-up structures that are previously not accounted for by other algorithms. Our method takes a novel image-domain approach to convert the input model to an OA design. It performs surface segmentation of the input model in the image domain, and carefully represents each surface with a set of parallel patches. Patches are then modified to make the entire structure foldable and stable. Visual and quantitative comparisons of results have shown our algorithm to be significantly better than the existing methods in the preservation of contours, surfaces and volume. The designs have also been shown to more closely resemble those created by real artists.

Ambient air is a core medium for monitoring of persistent organic pollutants (POPs) under the Stockholm Convention and is used in studies of global transports of POPs and their atmospheric sources and source regions. Still, data based on active air sampling remain scarce in many regions. The primary objectives of this study were to (i) monitor concentrations of selected POPs in air outside West Africa, and (ii) to evaluate potential atmospheric processes and source regions affecting measured concentrations. For this purpose, an active high-volume air sampler was installed on the Cape Verde Atmospheric Observatory at Cape Verde outside the coast of West Africa. Sampling commenced in May 2012 and 43 samples (24h sampling) were collected until June 2013. The samples were analyzed for selected polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), hexachlorobenzene (HCB) and chlordanes. The concentrations of these POPs at Cape Verde were generally low and comparable to remote sites in the Arctic for several compounds. Seasonal trends varied between compounds and concentrations exhibited strong temperature dependence for chlordanes. Our results indicate net volatilization from the Atlantic Ocean north of Cape Verde as sources of these POPs. Air mass back trajectories demonstrated that air masses measured at Cape Verde were generally transported from the Atlantic Ocean or the North African continent. Overall, the low concentrations in air at Cape Verde were likely explained by absence of major emissions in areas from which the air masses originated combined with depletion during long-range atmospheric transport due to enhanced degradation under tropical conditions (high temperatures and concentrations of hydroxyl radicals).

The High Frequency Active Auroral Research Program (HAARP) facility was operated in conjunction with overpasses of the enhanced Polar Outflow Probe (ePOP) instruments on the Canadian CASSIOPE satellite. During these overpasses HAARP was operated in several different heating modes and regimes as diagnosed by the characteristics of Stimulated Electromagnetic Emissions (SEE) using ground-based receivers while simultaneously ePOP monitored in-situ HF and VLF signals, looked for ion and electron heating, and provided VHF and UHF signals for propagation effects studies. The e-POP suite of instruments and particularly the ePOP Radio Receiver Instrument (RRI) offer a unique combination diagnostics appropriate for studying the non-linear plasma effects generated high-power HF waves in the ionosphere. In this presentation, the initial results from ePOP observations from two separate 2014 measurement campaigns at HAARP (April 16 to April 29 and May 25 to June 9) will be discussed. Several innovative experiments were performed during the campaign. Experiments explored a wide range of ionospheric effects. These include: 1) Penetration of HF pump waves into the ionosphere via large and small scale irregularities, 2) effects of gyro-harmonic heating and artificial ionization layers, 3) effects of HAARP beam shape with O- and X-mode transmissions, 4) coupling of Lower Hybrid modes into Whistler waves, 5) D/E-region VLF generation in the ionosphere using VLF modulation of the HF pump 6) scattering of VHF and UHF signals and 7) scattering and non-linear modulation of a 9.5 MHz probe wave propagating through the region of the ionosphere modified by HAARP.

There are strong indications that a moderate intake of fatty fish decreases the risk of cardiovascular diseases due to its content of omega-3 fatty acids. Other studies indicate that fatty fish consumption increase the body burden of Persistent Organic Pollutants (POPs) and may thereby increase the risk of negative health effects. Many of the latter studies are based on POP analysis of fatty fish, from which a recommended daily intake for humans has been calculated based on the no-observed adverse effect level (NOAEL) obtained from animal studies. Studies investigating associations between human plasma concentrations of POPs and intake of marine food show deviating results. In this study we investigated associations between self-reported intake of marine food (fatty fish, fish liver, fish liver oil, seagull eggs and halibut) and plasma concentrations of POPs. The study group consisted of 44 women and 16 men from northern Norway with a marine based diet. In addition to donate blood samples, the participants answered a detailed food frequency questionnaire with special emphasis on marine food consumption. Concentrations of 25 different POPs were measured in plasma. PCB 153 and p'p-DDE were the most ubiquitous PCB and chlorinated pesticide and the geometric mean concentrations were 73 ng/g lipids and 116 ng/g lipids respectively. The main findings in this study were that age, gender and intake of fresh fish liver oil were significant predictors of three of the most common PCBs and trans-Nonachlor in this study group. In addition, intake of seagull eggs influenced the concentration of PCB 180. However, even though the participants had a high intake of marine food they did not have elevated levels of POPs compared to other study groups. Intake of fatty fish did not significantly affect the body burden of POPs in this study group.

Persistent organic pollutants (POPs) are toxic substances and so harmful for human health. Mitigation of these emissions are internationally addressed by the Convention on Long-range Transboundary Air Pollution and by the Stockholm Convention. A global insight on POPs emissions evolution is essential since they can be transported long distances, they bio-accumulate and damage the environment. The Emission Database for Global Atmospheric Research (EDGARv4) is currently updated with POPs. We have estimated the global emissions of Polychlorinated biphenyls (PCBs), Polychlorinated dibenzo-p-dioxins (PCDDs), Polychlorinated dibenzofurans (PCDFs), Polycyclic aromatic hydrocarbons (PAHs) (benzo[a]pyrene (BaP), benzo[b]fluoranthene (BbF), benzo[k]fluoranthene (BkF), Indeno[1,2,3-cd]pyrene (IcdP)) and Hexachlorobenzene (HCB) from fuel combustion in the power generation, residential and transport sectors. This emissions inventory has been developed by using as input to the EDGAR technology-based emissions calculation algorithm the fossil fuel consumption data from International Energy Agency (2014) and the emission factors from EMEP/EEA (2013). We provide a complete emission time series for the period 1970-2010 and discuss the trends. A comprehensive analysis of the contribution of East Asia region to the total global will be provided for each substance of the POPs group. An example is presented in Figure 1 for BaP emissions from residential sector; with emissions mainly from China, the East Asia region has a great share (32%) in the total global. We distributed the POPs emissions on gridmaps of 0.1°x0.1° resolution. Areas with high emissions in East Asia will be presented and discussed; Figure 2 shows the hot-spots in East Asia for BaP emissions from the residential sector. These emission gridmaps, used as input for the chemical transport models, contribute to the improvement of impact evaluation, which is a key element in measuring the effectiveness of mitigation

Steam pop is an explosive rupture of cardiac tissue caused by tissue overheating above 100 °C, resulting in steam formation, predisposing to serious complications associated with radiofrequency (RF) ablations. However, there are currently no reliable techniques to predict the occurrence of steam pops. We propose the utility of acoustic signals emitted during RF ablation as a novel method to predict steam pop formation and potentially prevent serious complications. Radiofrequency generator parameters (power, impedance, and temperature) were temporally recorded during ablations performed in an in vitro bovine myocardial model. The acoustic system consisted of HTI-96-min hydrophone, microphone preamplifier, and sound card connected to a laptop computer. The hydrophone has the frequency range of 2 Hz to 30 kHz and nominal sensitivity in the range -240 to -165 dB. The sound was sampled at 96 kHz with 24-bit resolution. Output signal from the hydrophone was fed into the camera audio input to synchronize the video stream. An automated system was developed for the detection and analysis of acoustic events. Nine steam pops were observed. Three distinct sounds were identified as warning signals, each indicating rapid steam formation and its release from tissue. These sounds had a broad frequency range up to 6 kHz with several spectral peaks around 2-3 kHz. Subjectively, these warning signals were perceived as separate loud clicks, a quick succession of clicks, or continuous squeaking noise. Characteristic acoustic signals were identified preceding 80% of pops occurrence. Six cardiologists were able to identify 65% of acoustic signals accurately preceding the pop. An automated system identified the characteristic warning signals in 85% of cases. The mean time from the first acoustic signal to pop occurrence was 46 ± 20 seconds. The automated system had 72.7% sensitivity and 88.9% specificity for predicting pops. Easily identifiable characteristic acoustic emissions

2014-01-01

To investigate the functional field of view (FFOV) of younger and older individuals using the attended field of view (AFOV), a method which allows for eye and head movement. The impact of a pop out distracter and a dual task on the FFOV measure was also investigated. Nine young adult (25±6 years) and 9 older participants (72±4 years) took part in the experiment. The AFOV test involved the binocular detection and localization of a white target (Landolt-C) in a field of 24 white rings (distracters). The further AFOV tests were modified to include the presence of a pop out distracter, a dual task condition, and a combination of the two. Older observers had lower viewing efficiency (log [1/presentation time]) in all conditions (pooled mean across conditions: older: 0.05±0.02; younger: 0.48±0.04) than the younger group. The addition of dual or a pop out distracter did not affect the older group (mean difference ∼104±150ms and ∼124±122ms respectively) but the additional pop out distracter reduced the efficiency of the younger group for targets near fixation (mean difference ∼68±35ms). Better viewing efficiency was observed in younger individuals compared to older individuals. Difficulty in disregarding irrelevant stimuli and thereby resorting to inefficient search strategy is proposed as the reason for the differences. The finding that both older and younger individuals are not affected significantly by the presence of the irrelevant pop out distracter has implications in situations such as driving or hazard avoidance. In such scenarios, search performance is likely not impaired beyond what is found with distracters (visual clutter) in the environment. Copyright © 2013 Spanish General Council of Optometry.

Biological transport of persistent organic pollutants (POPs) to Lake Ellasjoeen, Bjoernoeya (Bear Island), Norway

During recent years, multidisciplinary studies have been carried out on Bjoernoeya (Bear Island, Norway), elucidating the fate and the presence of persistent organic pollutants (POPs) in this pristine Arctic environment. High concentrations of POPs, like polychlorinated biphenyls (PCBs), dichloro-diphenyl-dichlorethane (DDE) and polybrominated diphenyl ethers (PBDEs) have been measured in sediment and biota from Ellasjoeen, a lake located in the southern, mountainous part of Bjoernoeya. In Lake Oeyangen, located only 6 km north of Ellasjoeen on the central plains of the island, levels of POPs are several times lower than in Ellasjoeen. One reason for the different POP contamination levels in Ellasjoeen and Oeyangen is probably differences in precipitation regime between the southern mountainous part of the island and the central plains further north, leading to differences in the deposition of air transported contaminants. Another possible source for contaminants to Ellasjoeen is the large colonies of seabirds (mainly kittiwake (Rissa tridactyla), little auk (Alle alle) and glaucous gull (Larus hyperboreus)), which are situated close to the lake during the ice-free period (early June - October). These seabirds feed in the marine environment, and deposit large amounts of guano (excrements) directly into the lake or in the catchment area of the lake. Oeyangen is not influenced by seabirds. There are two ways in which input from seabirds can lead to higher levels of POPs in Ellasjoeen: direct input of POPs through allochthonous material (guano, bird remains) a change in trophic state of the lake as a result of nutrient loadings from the seabirds. The aim of the present study was to investigate the role of guano as a transport medium for POPs to Ellasjoeen. Two main approaches were followed: an investigation of the trophic status of Ellasjoeen, as well as the reference lake, Oeyangen, through analyses of stable isotopes of carbon and nitrogen, analyses of selected

Risk assessment of infant using a realistic persistent organic pollutant (POP) exposure through breast milk is essential to devise future regulation of POPs. However, recent investigations have demonstrated that POP levels in breast milk collected from the same mother showed a wide range of variation daily and monthly. To estimate the appropriate sample size of breast milk from the same mother to obtain reliable POP concentrations, breast milk samples were collected from five mothers living in Japan from 2006 to 2012. Milk samples from each mother were collected 3 to 6 times a day through 3 to 7 days consecutively. Food samples as the duplicated method were collected from two mothers during the period of breast milk sample collection. Those were employed for POP (PCBs, DDTs, chlordanes, and HCB) analysis. PCB concentrations detected in breast milk samples showed a wide range of variation which was maximum 63 and 60% of relative standard deviation (RSD) in lipid and wet weight basis, respectively. The time course trend of those variations among the mothers did not show any typical pattern. A larger amount of PCB intake through food seemed to affect 10 h after those concentrations in breast milk in lipid weight basis. Intraclass correlation coefficient (ICC) analyses indicated that the appropriate sample size for good reproducibility of POP concentrations in breast milk required at least two samples for lipid and wet weight basis.

POP bioaccumulation in macroinvertebrates of alpine freshwater systems

International Nuclear Information System (INIS)

Bizzotto, E.C.; Villa, S.; Vighi, M.

2009-01-01

This study serves to investigate the uptake of POPs in the different trophic levels (scrapers, collectors, predators, shredders) of macroinvertebrate communities sampled from a glacial and a non-glacial stream in the Italian Alps. The presented results show that the contaminant concentrations in glacial communities are generally higher compared to those from non-glacial catchments, highlighting the importance of glaciers as temporary sinks of atmospherically transported pollutants. Moreover, the data also suggests that in mountain systems snow plays an important role in influencing macroinvertebrate contamination. The main chemical uptake process to the macroinvertebrates is considered to be bioconcentration from water, as similar contaminant profiles were observed between the different trophic levels. The role of biomagnification/bioaccumulation is thought to be absent or negligible. The enrichment of chemicals observed in the predators is likely to be related to their greater lipid content compared to that of other feeding groups. - Influence of POP release in glacial-fed streams, enhanced by global warming, on pristine aquatic ecosystems.

2018-03-01

Obsessive-compulsive personality disorder (OCPD) has been subject to numerous definition and classification changes, which has contributed to difficulties in reliable measurement of the disorder. Consequently, OCPD measures have yielded poor validity and inconsistent prevalence estimates. Reliable and valid measures of OCPD are needed. The aim of the current study was to examine the factor structure and psychometric properties of the Pathological Obsessive Compulsive Personality Scale (POPS). Participants (N = 571 undergraduates) completed a series of self-report measures online, including the POPS. Confirmatory factor analysis was used to compare the fit of unidimensional, five factor, and bifactor models of the POPS. Convergent and divergent validity were assessed in relation to other personality dimensions. A bifactor model provided the best fit to the data, indicating that the total POPS scale and four subscales can be scored to obtain reliable indicators of OCPD. The POPS was most strongly associated with a disorder-specific measure of OCPD, however there were also positive associations with theoretically disparate constructs, thus further research is needed to clarify validity of the scale.

Pop hole passages and welfare in furnished cages for laying hens.

Science.gov (United States)

Wall, H; Tauson, R; Elwinger, K

2004-02-01

1. This study included two designs of furnished cages for 16 hens; H-cages divided into two apartments by a partition with pop holes in the middle of the cage, and fully open O-cages, without a partition. The hypothesis was that in this rather large group of birds the pop hole partition would benefit the birds by allowing them to avoid or escape from potential cannibals, feather-peckers or aggressive hens. All cages had two nests, two perches and one litter box. 2. A total of 10 cages (5 H and 5 O) were stocked with Lohmann Selected Leghorn (LSL) and 8 cages (4 H and 4 O) with Hy-Line W36. No birds were beak-trimmed. 3. Heterophil/lymphocyte (H/L) ratios, duration of tonic immobility (TI) and exterior appearance (scoring of plumage condition and wounds at comb or around cloaca) were used as indicators of well-being. Total mortality and deaths due to cannibalism were also recorded. 4. Visits to nests and passages through partition pop holes were studied in samples of 35 and 21 birds, respectively, using a technique based on passive integrated transponder (PIT) tags. 5. Cage design (H- vs O-cage) had no effect on the welfare traits chosen. 6. Hy-Line birds showed higher H/L ratios, longer duration of TI and better plumage condition than LSL birds. These differences are discussed in terms of stress thresholds and copying strategies. 7. On days when a hen made visits to nests, the visiting frequency was 1.4 and the total time in the nest was 41 min on average. Hens made use of the pop hole passages between 1 and 8 times per hen and day. 8. Overall low levels of aggression, lack of injuries or deaths due to cannibalism, and plumage condition indicating moderate feather pecking, together imply a low need to escape. The pop holes were used frequently and birds distributed well between compartments showing that the system worked well. However, at this group size there was no evidence in the measured traits that H-cages provided a better housing environment.

Pop-rock musicians are at risk of developing hearing loss and other symptoms related to amplified music. The aim of the present study was to assess the satisfaction provided by the use of hearing protection in pop-rock musicians. Contemporary cohort study. A study of 23 male pop-rock musicians, aged between 25 to 45 years. After audiological evaluation (pure tone audiometry, middle ear analysis, TEOAE and DPOAE) hearing protective devices were provided to be used for three months. After that musicians answered a satisfaction assessment questionnaire. The prevalence of hearing loss was of 21.7%. The most common complaints about the hearing protectors were: autophonia, pressure in the ears, interference in high frequencies perception and full time use of the hearing protector during concerts. There was a positive correlation between a reduction in tinnitus after the use of the HPD with the following complaints: tinnitus after beginning the career (p= 0.044), discomfort with the sound intensity in the work place (p= 0.009) and intolerance to loud sound (p= 0.029). There was a high prevalence of hearing loss and a positive tendency towards the use of the ear protector device among the sample population.

The fate and the mass balance of persistent organic pollutants (POPs) during the conventional activated sludge treatment process were investigated in the wastewater treatment plant of the city of Thessaloniki, northern Greece. The POPs of interest were 7 polychlorinated biphenyls and 19 organochlorine pesticides. Target compounds were determined at six different points across the treatment system: the influent, the effluent of the primary sedimentation tank, the effluent of the secondary sedimentation tank, the primary sludge, the activated sludge from the recirculation stream, and the digested/dewatered sludge. The distribution of POPs between the dissolved and the adsorbed phases of wastewater and sludge was investigated. A good linear relationship between the distribution coefficients, K d , and the octanol-water partition coefficients, K ow , of the solutes was observed only in raw wastewater, suggesting that other factors affect the phase distribution of organic compounds in treated wastewater. For all POPs, a significant increase in partitioning with a decreasing solids concentration was observed, revealing an effect from non-settling microparticles remaining in the 'dissolved' phase during the separation procedure. A good linear relationship was also revealed between logK d and the dissolved organic carbon (DOC) content of wastewater, suggesting that DOC favors the advective transport of POPs in the dissolved phase. Almost all POPs showed good mass balance agreements at both the primary and the secondary treatment. The losses observed for some species could be attributed to biodegradation/biotransformation rather than volatilization. The relative distribution between the treated effluent and the waste sludge streams varied largely among different compounds, with p-p'-DDE being highly accumulated in the waste sludge (98%) but almost 60% of α-HCH remaining in the treated effluent

Long-range transport and global fractionation of POPs: insights from multimedia modeling studies

Scheringer, M.; Salzmann, M.; Stroebe, M.; Wegmann, F.; Fenner, K.; Hungerbuehler, K.

The long-range transport of persistent organic pollutants (POPs) is investigated with two multimedia box models of the global system. ChemRange is a purely evaluative, one-dimensional steady-state (level III) model; CliMoChem is a two-dimensional model with different temperatures, land/water ratios and vegetation types in different latitudinal zones. Model results are presented for three case studies: (i) the effect of atmospheric aerosol particles on the long-range transport of POPs, (ii) the effect of oceanic deposition on the long-range transport of different PCB congeners, (iii) the global fractionation of different PCB congeners. The model results for these case studies show: (i) the low atmospheric half-lives estimated for several organochlorine pesticides are likely to be inconsistent with the observed long-range transport of these compounds; (ii) export to the deep sea reduces the potential for long-range transport of highly hydrophobic compounds (but does not remove these chemicals from the biosphere); (iii) there are different meanings of the term global fractionation that refer to different aspects of the fractionation process and need to be distinguished. The case-study results further indicate that the influences of varying environmental conditions on the physicochemical properties and the degradation rate constants of POPs need to be determined. - Multimedia box models are applied to case studies of the behavior of POPs

Microplastics are not important for the cycling and bioaccumulation of organic pollutants in the oceans-but should microplastics be considered POPs themselves?

Science.gov (United States)

Lohmann, Rainer

2017-05-01

The role of microplastic particles in the cycling and bioaccumulation of persistent organic pollutants (POPs) is discussed. Five common concepts, sometimes misconceptions, about the role of microplastics are reviewed. While there is ample evidence that microplastics accumulate high concentrations of POPs, this does not result in microplastics being important for the global dispersion of POPs. Similarly, there is scant evidence that microplastics are an important transfer vector of POPs into animals, but possibly for plastic additives (flame retardants). Last, listing microplastics as POPs could help reduce their environmental impact. Integr Environ Assess Manag 2017;13:460-465. © 2017 SETAC. © 2017 SETAC.

2010-01-01

Full text: A 30 kW DC plasma-arc reactor has been used to destruct hazardous Persistent Organic Pollutants (POPs) and the destruction and removal efficiency (DRE) of POPs is investigated. Due to similar to several POPs at chemical structure such as DDT, PCBs, pure chlorobenzene (C 6 H 5 Cl) is selected as the experimental material. Because the arc temperature attains 5000 K and the average temperature exceeds 1600 K in reaction area, the chlorinated organics, which are difficult to be destructed in conventional incinerators, can be rapidly pyrolyzed into simple molecules. Detected by Gas Chromatography (CP-3800 Varian), the off-gas is a mixture of H 2 , HCl and some hydrocarbons such as CH 4 , C 2 H 2 , C 2 H 4 , and C 6 H 5 Cl is not detected in the off-gas. Furthermore, the treatment of POPs in a steam-plasma system has been simulated. The process acts as energy transformation - electrical energy is restored in the syngas. Based on the principle of Gibbs free energy minimum, the equilibrium product distribution versus steam content and temperature is calculated. At the ideal temperature of POPs treatment, the energy recovered (Qre) minus the energy input (Qin) gets to maximum while the molar ration of oxygen to carbon (O/C) is near 1. The results show that the plasma-arc technology is environmentally friendly and economically feasible for disposal of POPs. (author)

A Conserved EAR Motif Is Required for Avirulence and Stability of the Ralstonia solanacearum Effector PopP2 In Planta

Directory of Open Access Journals (Sweden)

Cécile Segonzac

2017-08-01

Full Text Available Ralstonia solanacearum is the causal agent of the devastating bacterial wilt disease in many high value Solanaceae crops. R. solanacearum secretes around 70 effectors into host cells in order to promote infection. Plants have, however, evolved specialized immune receptors that recognize corresponding effectors and confer qualitative disease resistance. In the model species Arabidopsis thaliana, the paired immune receptors RRS1 (resistance to Ralstonia solanacearum 1 and RPS4 (resistance to Pseudomonas syringae 4 cooperatively recognize the R. solanacearum effector PopP2 in the nuclei of infected cells. PopP2 is an acetyltransferase that binds to and acetylates the RRS1 WRKY DNA-binding domain resulting in reduced RRS1-DNA association thereby activating plant immunity. Here, we surveyed the naturally occurring variation in PopP2 sequence among the R. solanacearum strains isolated from diseased tomato and pepper fields across the Republic of Korea. Our analysis revealed high conservation of popP2 sequence with only three polymorphic alleles present amongst 17 strains. Only one variation (a premature stop codon caused the loss of RPS4/RRS1-dependent recognition in Arabidopsis. We also found that PopP2 harbors a putative eukaryotic transcriptional repressor motif (ethylene-responsive element binding factor-associated amphiphilic repression or EAR, which is known to be involved in the recruitment of transcriptional co-repressors. Remarkably, mutation of the EAR motif disabled PopP2 avirulence function as measured by the development of hypersensitive response, electrolyte leakage, defense marker gene expression and bacterial growth in Arabidopsis. This lack of recognition was partially but significantly reverted by the C-terminal addition of a synthetic EAR motif. We show that the EAR motif-dependent gain of avirulence correlated with the stability of the PopP2 protein. Furthermore, we demonstrated the requirement of the PopP2 EAR motif for PTI

At high trophic levels, environmental contaminants have been found to affect endocrinological processes. Less attention has been paid to species at lower trophic levels. The house sparrow (Passer domesticus) may be a useful model for investigating effects of POPs in mid-range trophic level species. In male house sparrows, ornamental traits involved in male quality signalling are important for female selection. These traits are governed by endocrinological systems, and POPs may therefore interfere with male quality signalling. The aim of the present study was to use the house sparrow as a mid-range trophic level model species to study the effects of environmental contaminants on endocrinology and male quality signalling. We analysed the levels of selected PCBs, PBDEs and OCPs and investigated the possible effects of these contaminants on circulating levels of steroid hormones (4 progestagens, 4 androgens and 3 estrogens) in male and female adult house sparrows from a population on the island Leka, Norway. Plasma samples were analysed for steroid hormones by GC-MS and liver samples were analysed for environmental contaminants by GC-ECD and GC-MS. In males, we also quantified ornament traits. It was hypothesised that POPs may have endocrine disrupting effects on the local house sparrow population and can thus interfere with the steroid hormone homeostasis. Among female house sparrows, bivariate correlations revealed negative relationships between POPs and estrogens. Among male sparrows, positive relationships between dihydrotestosterone levels and PCBs were observed. In males, positive relationships were also found between steroids and beak length, and between steroids and ornamental traits such as total badge size. This was confirmed by a significant OPLS model between beak length and steroids. Although sparrows are in the mid-range trophic levels, the present study indicates that POPs may affect steroid homeostasis in house sparrows, in particular for females. For

Small 'l' leadership.

Recently I attended the RACGP Leadership Masterclass in Sydney. When I enrolled, I thought, 'Yes... sounds interesting...good speakers... I need to learn something about leadership...'As the time drew closer I started to get a bit anxious about the whole thing. I realised that the title, 'Masterclass', probably implied that the attendees were expected to already know something about leadership and its theories, if not have considerable expertise and experience in leadership. I also wondered how the workshop sessions were going to go and I started to feel a bit sorry for the facilitators. Imagine trying to facilitate a group of 10 aspiring leaders... a bit like trying to herd cats. A few days later I received a call from the organisers,saying they were a bit short of facilitators and could I help out if necessary. Great... better do a crash course in cat herding! Then there was the first 'predisposing activity'. Step 1: think of leaders you admire. Easy enough. Leaders of social justice and social change on a world stage, people who have shown great courage of their convictions and great orators popped into my head... Ghandi, Martin Luther King, Mandela, JFK. Step 2:describe the ways in which you are like these leaders. Whoa!Never going to measure up here. I wondered if there was going to be sessions on 'leadership for introverts', or 'leadership of small things', or 'leaders without grand vision or fabulous oratory skills', or perhaps 'leadership for people who are deeply suspicious of the corrupting influence of power'.

Full Text Available Noise-induced hearing loss (NIHL has been extensively studied in industrial work environments. With the advent of new technologies, loud music has been increasingly affecting listeners outside of the industrial setting. Most research on the effects of music and hearing loss has focused on classical musicians. The purpose of the current study was to examine the relationship between the amount of experience a professional pop/rock/jazz musician has and objective and subjective variables of the musician′s hearing loss. This study also examined professional pop/rock/jazz musicians′ use of hearing protection devices in relation to the extent of their exposure to amplified music. Forty-four pop/rock/jazz musicians were interviewed using the Pop/Rock/Jazz Musician′s Questionnaire (PRJMQ in order to obtain self-reported symptoms of tinnitus and hyperacusis. Forty-two of the subjects were also tested for air-conduction hearing thresholds in the frequency range of 1-8 kHz. Results show that the extent of professional pop/rock/jazz musicians′ exposure to amplified music was related to both objective and subjective variables of hearing loss: Greater musical experience was positively linked to higher hearing thresholds in the frequency range of 3-6 kHz and to the subjective symptom of tinnitus. Weekly hours playing were found to have a greater effect on hearing loss in comparison to years playing. Use of hearing protection was not linked to the extent of exposure to amplified music. It is recommended that further research be conducted with a larger sample, in order to gain a greater understanding of the detrimental effects of hours playing versus years playing.

The language of poetic texts in contemporary Tuvan pop songs

Oyumaa M. Saaya

2017-06-01

Full Text Available The article presents a linguistic analysis of lyrics of modern Tuvan pop songs. While studying them is important for understanding contemporary songwriting in Tuva, it is also necessary to discover what linguistic means, functional styles and vocabulary are used by modern authors of popular lyrics. The study can also help identify how contemporary global trends influence songwriting in means of linguistics. Three groups of songs can be defined in Tuvan pop music. The first of them comprises songs written by both professional poets and amateurs with good writing skills. Their texts have homogenous literary style and are intended for general audience (rather than specific groups of listeners. They do not feature any jargon or youth slang. The second group consists of “songs of the people” which are still popular and relevant, but not classified as folklore. This group also contains songs previously banned by censorship, and those written by ex-convicts. Their lyrics differ in style, and the vocabulary is also heterogenous: they can include slang and contain vernacular language. The third group includes songs following popular global and Russian trends, which  triggered rapid evolution in Tuvan songwriting. There is significant number of authors or even creative unions, who write both lyric and music. They are stylistically uneven, contain a lot of neologisms, borrowed vocabulary, slang and jargon words and sometimes even macaronic (mixed language. The author provides a more in-depth analysis of lyrics belonging to the third group of songs. They can be divided into 6 thematic subgroups which greatly vary in lexical content and the use of tropes. The lyrics of contemporary Tuvan songs are quite close to the everyday language young people use. Active employment of jargon in the language of young and middle-aged people, especially in lyrics of modern songs, steadily decreases the literary norms of Tuvan language. The author emphasizes that

The detection of gravitational waves (GWs) generated by merging black holes has recently opened up a new observational window into the Universe. The mass of the black holes in the first and third Laser Interferometer Gravitational Wave Observatory (LIGO) detections (36-29 M⊙ and 32-19 M⊙) suggests low-metallicity stars as their most likely progenitors. Based on high-resolution N-body simulations, coupled with state-of-the-art metal enrichment models, we find that the remnants of Pop III stars are preferentially located within the cores of galaxies. The probability of a GW signal to be generated by Pop III stars reaches ∼90 per cent at ∼0.5 kpc from the galaxy centre, compared to a benchmark value of ∼5 per cent outside the core. The predicted merger rates inside bulges is ∼60 × βIII Gpc-3 yr-1 (βIII is the Pop III binarity fraction). To match the 90 per cent credible range of LIGO merger rates, we obtain: 0.03 proof for the existence of Pop III stars.

2017-01-01

Dental erosion is a common disease in children. Food diets, due to high amounts of juice, soft drinks, chewing gum, and acidic chocolate, are one of the most important risk factors in erosive processes among children. The aim of this study was to evaluate the effect of candy and chocolate on the microhardness of tooth enamel. Two types of popping candy and one type of popping chocolate were used in this study. Thirty-three healthy permanent premolar teeth and 33 primary incisor teeth (A or B) were selected. Five grams of each popping chocolate or candy was dissolved with 2 ml of artificial saliva. Subsequently, their pH and titrable acidity (TA) as well as microhardness and surface roughness of enamel were examined in the laboratory. Data were analyzed and evaluated Released 2011. IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY through independent t -test, paired t -test, Tukey test, and ANOVA. The results of this study showed that only the pH of the candies was below the critical pH of the enamel (5.5) and their TA was B = 0.20 and C = 0.21. The most significant effect on the enamel microhardness of the permanent and primary teeth was by the following types of candy: orange flavor (C), strawberry flavor (B), and chocolate (A), respectively. This difference was significant ( P < 0.001) and the surface roughness increased after exposure. This study showed that popping chocolate and candy reduces microhardness of enamel.

Myth about immortality in the contemporary pop culture: A case study about Toše Proeski

His sudden, untimely death in his twenties had exploded as huge news, preoccupying all sorts of media. What I am interested in this paper is what has happened afterwards. In which way his popularity and his afterlife continue? Can we identify some kind of pop hero cult here, and is it possible to recognize common elements, or even a pattern according to which (newborn stars develop an afterlife destiny? Can we use this opportunity to discuss immortality myths? Do pop stars get monuments or are these reserved just for national heroes?

Interactions of a Pop5/Rpp1 heterodimer with the catalytic domain of RNase MRP.

2011-10-01

Ribonuclease (RNase) MRP is a multicomponent ribonucleoprotein complex closely related to RNase P. RNase MRP and eukaryotic RNase P share most of their protein components, as well as multiple features of their catalytic RNA moieties, but have distinct substrate specificities. While RNase P is practically universally found in all three domains of life, RNase MRP is essential in eukaryotes. The structural organizations of eukaryotic RNase P and RNase MRP are poorly understood. Here, we show that Pop5 and Rpp1, protein components found in both RNase P and RNase MRP, form a heterodimer that binds directly to the conserved area of the putative catalytic domain of RNase MRP RNA. The Pop5/Rpp1 binding site corresponds to the protein binding site in bacterial RNase P RNA. Structural and evolutionary roles of the Pop5/Rpp1 heterodimer in RNases P and MRP are discussed.

Status of POPs accumulation in the Yellow River Delta: From distribution to risk assessment

Li, Jing; Chen, Chunli; Li, Fadong

2016-01-01

The Yellow River Delta (YRD) is a large region of China with complex pollution sources and a long history of environmental deterioration. Despite this, relatively little data exists on the status of important contaminants of concern in this region. Here, we review the literature on the status of key persistent organic pollutants (POPs) of concern including organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs) in the YRD. Sources, source identification methods, and spatial distribution patterns are presented. Additionally, POPs contamination levels reported in the literature were evaluated against popular regulatory limits worldwide to form a basis for overall environmental health. Our review determined that OCPs in the YRD originated mainly from current pesticide use and past agricultural pesticide application. Sources of PAHs included petrochemical inputs, coal fired plants, and wood combustion. PCB levels were impacted by the petrochemical industry as well as waste disposal of PCB containing equipment. OCPs exhibited a spatial distribution pattern that increased along the urban–rural gradient, while the opposite was seen for PAHs and PCBs. Comparisons of POPs contamination levels in the YRD with popular regulatory limits suggest that the extent of PCB contamination all mediums (sediment, soil, water, and biota) exceeded that of PAHs and OCPs. Overall pollution levels in the YRD seem to be in control; however, levels from heavily polluted point sources raise numerous concerns about the ecological health of the region and require more attention from regulatory authorities. - Highlights: •Previous usage of POPs, regulatory limits and source identification methods used in China and abroad were summarized. •Environment occurrence, source and risk of OCPs, PCBs and PAHs are reviewed. •Both OCPs and PAHs residue are relatively low, but PCBs residue is at a higher degree. •Spatial pattern of OCPs showed

Pop-ins on nanoindentation load-displacement curves of a ferritic steel were correlated with yield drops on its tensile stress-strain curves. To investigate the relationship between these two phenomena, nanoindentation and tensile tests were performed on annealed specimens, prestrained specimens, and specimens aged for various times after prestraining. Clear nanoindentation pop-ins were observed on annealed specimens, which disappeared when specimens were indented right after the prestrain, but reappeared to varying degrees after strain aging. Yield drops in tensile tests showed similar disappearance and appearance, indicating that the two phenomena, at the nano- and macro-scale, respectively, are closely related and influenced by dislocation locking by solutes (Cottrell atmospheres).

Accumulation of PCBs and other POPs in Canada's Arctic

High concentrations of polychlorinated biphenyls (PCBs) and other persistent organic pollutants (POPs) have been found in sea-food traditionally eaten by First Nations' people of the Arctic. Since PCBs have never been manufactured in the Arctic these high concentrations cannot be attributed to local sources; they must have been transported from other regions. Due to its cold climate, the Arctic acts a sink for contaminants such as PCBs, originating from around the world and carried by Arctic air masses. Semi-volatile compounds are carried to the Arctic by cycles of evaporation, transport and condensation. Rain, snow, ice and dry deposition capture the airborne contaminants and pollute the surface on which they settle. The contaminants are processed in rivers by sedimentation and resuspension of particles, and lakes, estuaries and deltas act as sinks. The effects of these contaminants is not fully understood, although it is clear that they accumulate in fatty tissues, thus posing special danger to First Nations people who are known to consume fatty sea mammals. Inuit adults from Arctic Quebec and Greenland have PCB concentrations in their blood seven times higher than found in North American adults; 35 times higher than Health Canada's 'level of concern' for women of reproductive age. The cleanup of all PCB and other POP sources is believed to be the only preventative solution, but agreement among countries about how to deal with the existing POPs in the environment to date has proven to be difficult.

Persistent Organic Pollutants (POPs) are toxic organic compounds resistant to environmental degradation. Besides, POPs bioaccumulation with potential significant impacts on human health and the environment. The Global Monitoring Plan (GMP) under the Stockholm Convention on POPs is a program that enables collection of comparable monitoring data from all regions of the world to assess the effectiveness in minimizing human and environmental exposure to POPs. The scope of this work is to develop and validate a method for the extraction and determination of POPs in sediments collected at Billings dam locate in São Paulo Metropolitan City. The compounds studied in this work are: Aldrin (C 12 H 8 C l6 ), DDD (C 14 H 10 C l4 ), DDE (C 14 H 8 Cl l4) , DDT (C 14 H 9 C l5 ), Dieldrin (C 12 H 8 C l6 O), Endrin (C 12 H 8 Cl 6 O) and Heptachlor (C 10 H 5 C l7 ). This work use the QuEChERS extraction method (Quick, Easy, Cheap, Effective, Rugged, and Safe) for sediment samples and the analysis of the compounds were carried out by gas chromatography with the electron capture detector (GC/ECD). The ECD detector ionizes the analytes by the beta particles from the nuclide sources 63 Ni within carrier gas N 2 . The electrons produced in this process are collected, create an amplified current, and generating the chromatographic peak. The recovery of this method obtained values between 57% and 65% and the Relative Standard Deviation (RSD) values are between 1 and 4%. Details of the analytical method beside quantitative analyses data are presented in this work. (author)

Persistent organic pollutants (POPs) are widespread throughout the environment and some are suspected to induce reproductive toxicity. As animals and humans are exposed to complex mixtures of POPs, it is reasonable to assess how such mixtures could interact with the reproductive system. Our aim is to investigate how maternal exposure to a mixture of 29 different persistent organic pollutants, formulated to mimic the relative POP levels in the food basket of the Scandinavian population, could alter reproductive endpoints. Female mice were exposed via feed from weaning, during pregnancy and lactation in 3 exposure groups (control (C), low (L) and high (H)). Testicular morphometric endpoints, epididymal sperm concentration and sperm DNA integrity were assessed in adult male offspring. We found that the number of tubules, proportion of tubule compartments and epididymal sperm concentration significantly decreased in both POP exposed groups. Epididymal sperm from both POP exposed groups showed increased DNA fragmentation. It is concluded that maternal exposure to a defined POP mixture relevant to human exposure can affect testicular development, sperm production and sperm chromatin integrity.

Full Text Available The purpose of this study is to examine jilbab as a pop culture and Indonesian moslem identity. The use of jilbab (a headscarf or a head covering for moslem women has gained its popularity since the last twenty year. This phenomenon is interesting to be investigated particularly from diverse jilbab or veiling practices in many different ways. Indonesian moslem women, for instance, used styles of jilbab and fashion which are different from those worn by moslem women in other countries. Hence, this shows characteristics of Indonesian moslem women in wearing or using jilbab which becomes an identity. Many scholars see identity as a product of social construction, and a fluid concept. This is due to the emergence of various identities resulted from different contexts. For the theoretical framework, this study uses Barthes semiotic analysis to interpret and decode the signs attached to jilbab and Indonesian moslem fashion as a part of pop culture and a new identity. The result of the study indicates that jilbab as a headscarf changes from time to time in terms of its use and styles. Jilbab styles worn by Indonesian moslem women adopted both local and global styles. This demonstrates the hybrid identity of Indonesian moslem women in wearing or using jilbab.

Mutants of GABA transaminase (POP2 suppress the severe phenotype of succinic semialdehyde dehydrogenase (ssadh mutants in Arabidopsis.

Directory of Open Access Journals (Sweden)

Frank Ludewig

Full Text Available BACKGROUND: The gamma-aminubutyrate (GABA shunt bypasses two steps of the tricarboxylic acid cycle, and is present in both prokaryotes and eukaryotes. In plants, the pathway is composed of the calcium/calmodulin-regulated cytosolic enzyme glutamate decarboxylase (GAD, the mitochondrial enzymes GABA transaminase (GABA-T; POP2 and succinic semialdehyde dehydrogenase (SSADH. We have previously shown that compromising the function of the GABA-shunt, by disrupting the SSADH gene of Arabidopsis, causes enhanced accumulation of reactive oxygen intermediates (ROIs and cell death in response to light and heat stress. However, to date, genetic investigations of the relationships between enzymes of the GABA shunt have not been reported. PRINCIPAL FINDINGS: To elucidate the role of succinic semialdehyde (SSA, gamma-hydroxybutyrate (GHB and GABA in the accumulation of ROIs, we combined two genetic approaches to suppress the severe phenotype of ssadh mutants. Analysis of double pop2 ssadh mutants revealed that pop2 is epistatic to ssadh. Moreover, we isolated EMS-generated mutants suppressing the phenotype of ssadh revealing two new pop2 alleles. By measuring thermoluminescence at high temperature, the peroxide contents of ssadh and pop2 mutants were evaluated, showing that only ssadh plants accumulate peroxides. In addition, pop2 ssadh seedlings are more sensitive to exogenous SSA or GHB relative to wild type, because GHB and/or SSA accumulate in these plants. SIGNIFICANCE: We conclude that the lack of supply of succinate and NADH to the TCA cycle is not responsible for the oxidative stress and growth retardations of ssadh mutants. Rather, we suggest that the accumulation of SSA, GHB, or both, produced downstream of the GABA-T transamination step, is toxic to the plants, resulting in high ROI levels and impaired development.

A comparison of POPs bioaccumulation in Eisenia fetida in natural and artificial soils and the effects of aging

International Nuclear Information System (INIS)

Vlčková, Klára; Hofman, Jakub

2012-01-01

The close relationship between soil organic matter and the bioavailability of POPs in soils suggests the possibility of using it for the extrapolation between different soils. The aim of this study was to prove that TOC content is not a single factor affecting the bioavailability of POPs and that TOC based extrapolation might be incorrect, especially when comparing natural and artificial soils. Three natural soils with increasing TOC and three artificial soils with TOC comparable to these natural soils were spiked with phenanthrene, pyrene, lindane, p,p′-DDT, and PCB 153 and studied after 0, 14, 28, and 56 days. At each sampling point, total soil concentration and bioaccumulation in earthworms Eisenia fetida were measured. The results showed different behavior and bioavailability of POPs in natural and artificial soils and apparent effects of aging on these differences. Hence, direct TOC based extrapolation between various soils seems to be limited. - Highlights: ► Artificial and natural soils with the same TOC content were used in this study. ► BAF and total concentration of five POPs were measured during 56 days after spiking. ► Bioaccumulation was significantly lower in NS than in AS with the same TOC. ► Direct extrapolation according to TOC was possible for soils with levels >10%. ► Microbial degradation probably influences PAHs bioavailability. - Organic matter is an important factor in the bioavailability of POPs in soils, but direct extrapolation based on TOC content might lead to incorrect results in risk assessment.

The aim of this study was to determine the effects of persistent organic pollutants (POPs) and biometric variables on circulating levels of steroid hormones (androgens, estrogens and progestagens) in male polar bears (Ursus maritimus) from Svalbard, Norway (n = 23). Levels of pregnenolone (PRE), progesterone (PRO), androstenedione (AN), dehydroepiandrosterone (DHEA), testosterone (TS), dihydrotestosterone (DHT), estrone (E1), 17α-estradiol (αE2) and 17β-estradiol (βE2) were quantified in polar bear serum by gas chromatography tandem mass spectrometry (GC-MS/MS), while POPs were measured in plasma. Subsequently, associations between hormone concentrations (9 steroids), POPs (21 polychlorinated biphenyls (PCBs), 8 OH-PCBs, 8 organochlorine pesticides (OCPs) and OCP metabolites, and 2 polybrominated diphenyl ethers (PBDEs)) and biological variables (age, head length, body mass, girth, body condition index), capture date, location (latitude and longitude), lipid content and cholesterol levels were examined using principal component analysis (PCA) and orthogonal projections to latent structures (OPLS) modelling. Average concentrations of androgens, estrogens and progestagens were in the range of 0.57-83.7 (0.57-12.4 for subadults, 1.02-83.7 for adults), 0.09-2.69 and 0.57-2.44 nmol/L, respectively. The steroid profiles suggest that sex steroids were mainly synthesized through the Δ-4 pathway in male polar bears. The ratio between androgens and estrogens significantly depended on sexual maturity with androgen/estrogen ratios being approximately 60 times higher in adult males than in subadult males. PCA plots and OPLS models indicated that TS was positively related to biometrics, such as body condition index in male polar bears. A negative relationship was also observed between POPs and DHT. Consequently, POPs and body condition may potentially affect the endocrinological function of steroids, including development of reproductive tissues and sex organs and the

Elvis to Eminem: quantifying the price of fame through early mortality of European and North American rock and pop stars.

Rock and pop stars are frequently characterised as indulging in high-risk behaviours, with high-profile deaths amongst such musicians creating an impression of premature mortality. However, studies to date have not quantified differences between mortality experienced by such stars and general populations. This study measures survival rates of famous musicians (n = 1064) from their point of fame and compares them to matched general populations in North America and Europe. We describe and utilise a novel actuarial survival methodology which allows quantification of excess post-fame mortality in pop stars. Individuals from North America and Europe performing on any album in the All-Time Top 1000 albums from the music genres rock, punk, rap, R&B, electronica and new age. From 3 to 25 years post fame, both North American and European pop stars experience significantly higher mortality (more than 1.7 times) than demographically matched populations in the USA and UK, respectively. After 25 years of fame, relative mortality in European (but not North American) pop stars begins to return to population levels. Five-year post-fame survival rates suggest differential mortality between stars and general populations was greater in those reaching fame before 1980. Pop stars can suffer high levels of stress in environments where alcohol and drugs are widely available, leading to health-damaging risk behaviour. However, their behaviour can also influence would-be stars and devoted fans. Collaborations between health and music industries should focus on improving both pop star health and their image as role models to wider populations.

OntoPop: An Ontology Population System for the Semantic Web

Science.gov (United States)

Thongkrau, Theerayut; Lalitrojwong, Pattarachai

The development of ontology at the instance level requires the extraction of the terms defining the instances from various data sources. These instances then are linked to the concepts of the ontology, and relationships are created between these instances for the next step. However, before establishing links among data, ontology engineers must classify terms or instances from a web document into an ontology concept. The tool for help ontology engineer in this task is called ontology population. The present research is not suitable for ontology development applications, such as long time processing or analyzing large or noisy data sets. OntoPop system introduces a methodology to solve these problems, which comprises two parts. First, we select meaningful features from syntactic relations, which can produce more significant features than any other method. Second, we differentiate feature meaning and reduce noise based on latent semantic analysis. Experimental evaluation demonstrates that the OntoPop works well, significantly out-performing the accuracy of 49.64%, a learning accuracy of 76.93%, and executes time of 5.46 second/instance.

2006-08-01

The purpose of this study was to evaluate the hearing and subjective auditory symptoms in a group of nonprofessional pop/rock musicians who had experienced repeated exposures to intense sound levels during at least 5 yr of musical activity. An evaluation of both ears in 42 nonprofessional pop/rock musicians included pure-tone audiometry in the conventional and extended high-frequency range, the measurement of uncomfortable loudness levels, and an assessment of tinnitus and hypersensitivity to sound. Exclusion criteria were (a) the occurrence of acoustic trauma, (b) excessive noise exposure during occupational activities, (c) a history of recurrent otitis media, (d) previous ear surgery, (e) a fracture of the cranium, (f) ingestion of potentially ototoxic drugs, and (g) reported hearing difficulties within the immediate family. These audiometric results were then compared with a control group of 20 otologically normal young adults with no history of long-term noise exposure. After adjusting for age and gender, relative to ISO 7029, the mean hearing threshold in the frequency range of 3 to 8 kHz was 6 dB in the musicians and 1.5 dB in the control group. This difference was statistically significant (Mann-Whitney rank sum test, p rock musicians who had experienced repeated exposure to intense sound levels over at least 5 yr but with minimal impact on their lives. Moreover, hearing loss was minimal in the subjects who always used ear protection, being only 0.9 dB higher than the control group. In contrast, hearing loss was significantly more pronounced, at 6.7 dB higher than the control group, in those musicians who never used ear protection. Continued education about the risk to hearing and the benefits of the persistent use of ear protection is warranted for musicians who are exposed frequently to intense sound levels.

Modelling atmospheric transport of α-hexachlorocyclohexane in the Northern Hemispherewith a 3-D dynamical model: DEHM-POP

Full Text Available The Danish Eulerian Hemispheric Model (DEHM is a 3-D dynamical atmospheric transport model originally developed to describe the atmospheric transport of sulphur into the Arctic. A new version of the model, DEHM-POP, developed to study the atmospheric transport and environmental fate of persistent organic pollutants (POPs is presented. During environmental cycling, POPs can be deposited and re-emitted several times before reaching a final destination. A description of the exchange processes between the land/ocean surfaces and the atmosphere is included in the model to account for this multi-hop transport. The α-isomer of the pesticide hexachlorocyclohexane (α-HCH is used as tracer in the model development. The structure of the model and processes included are described in detail. The results from a model simulation showing the atmospheric transport for the years 1991 to 1998 are presented and evaluated against measurements. The annual averaged atmospheric concentration of α-HCH for the 1990s is well described by the model; however, the shorter-term average concentration for most of the stations is not well captured. This indicates that the present simple surface description needs to be refined to get a better description of the air-surface exchange processes of POPs.

The main power supply of Proton-Synchrotron (PS) accelerator is one of the biggest at CERN. The old rotating machine system has been replaced with a new NPC based DC/DC power supply named POPS (Power system for PS main magnets) with capacitor banks as energy storage mean. POPS is in operation since February 2011. The operation of the PS accelerator requires a specific design of the control system with very high performance requirements in term of accuracy and precision. This paper describes the main lines of the control strategies analyzing the problems encountered and the solutions adopted. The performances of the converter are presented throughout the paper.

'Pop-Up' Governance: developing internal governance frameworks for consortia: the example of UK10K.

2015-01-01

Innovations in information technologies have facilitated the development of new styles of research networks and forms of governance. This is evident in genomics where increasingly, research is carried out by large, interdisciplinary consortia focussing on a specific research endeavour. The UK10K project is an example of a human genomics consortium funded to provide insights into the genomics of rare conditions, and establish a community resource from generated sequence data. To achieve its objectives according to the agreed timetable, the UK10K project established an internal governance system to expedite the research and to deal with the complex issues that arose. The project's governance structure exemplifies a new form of network governance called 'pop-up' governance. 'Pop-up' because: it was put together quickly, existed for a specific period, was designed for a specific purpose, and was dismantled easily on project completion. In this paper, we use UK10K to describe how 'pop-up' governance works on the ground and how relational, hierarchical and contractual governance mechanisms are used in this new form of network governance.

Alfvénic Dynamics and Fine Structuring of Discrete Auroral Arcs: Swarm and e-POP Observations

The electrodynamics associated with dual discrete arc aurora with anti-parallel flow along the arcs were observed nearly simultaneously by the enhanced Polar Outflow Probe (e-POP) and the Swarm A and C spacecraft. Auroral imaging from e-POP reveal 1-10 km structuring of the arcs, which move and evolve on second timescales and confound the traditional single-spacecraft field-aligned current algorithms. High-cadence magnetic data from e-POP shows 1-10 Hz, presumably Alfvénic perturbations co-incident with and at the same scale size as the observed dynamic auroral fine structures. High-cadence electric and magnetic field data from Swarm A reveals non-stationary electrodynamics involving reflected and interfering Alfvén waves and signatures of modulation consistent with trapping in the Ionospheric Alfvén Resonator (IAR). Together, these observations suggest a role for Alfven waves, perhaps also the IAR, in discrete arc dynamics on 0.2 - 10s timescales and 1-10 km spatial scales.

Current status and regulatory aspects of pesticides considered to be persistent organic pollutants (POPs) in Taiwan.

Tsai, Wen-Tien

2010-10-01

Organochlorine pesticides (OCPs) are capable of persisting in the environment, transporting between phase media and accumulating to high levels, implying that they could pose a risk of causing adverse effects to human health and the environment. Consequently, most OCPs are designated as persistent organic pollutants (POPs) and even as endocrine disrupting chemicals (EDCs). The objective of this paper was to review the current status of pesticide POPs in Taiwan, including aldrin, chlordane, chlordecone, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene, α/β-hexachlorocyclohexanes, lindane, mirex, pentachloro-benzene, and toxaphene. The information about their environmental properties, banned use, carcinogenic toxicity and environmental levels, can be connected with the regulatory infrastructure, which has been established by the joint-venture of the central competent authorities (i.e., Environmental Protection Administration, Department of Health, Council of Agriculture, and Council of Labor Affairs). The significant progress to be reported is that the residual levels of these pesticide-POPs, ranging from trace amounts to a few ppb, have declined notably in recent years.

Full Text Available This paper tries to resolve the puzzle firstly: how can Korean pop (K-Pop become transbordering since Korean is not the main language in the world? It can be attributed to the policy input and capital integration, the textual circulation through emerging audio-video platform on-line, as well as the specific textual form with intensive visuality and embodiment. This paper applies not only traditionally visual-textual analysis but also the new methodology called “following the object” by the British sociologists Scott Lash and Celia Lury. The researcher regards K-Pop as an object of cross-cultural consumption and tracks its circulation from local production to “glocal” consumption. Through the interview to the K-Pop professionals, review of the relevant articles, textual analysis of the music videos and the ethnographic fieldwork of local fans community, this paper tries to answer the two questions: (1 how does K-Pop produce itself by the strategies of visualization and embodiment, as well as gendered performance; (2 how do the fans appropriate the K-Pop texts to re-perform and re-shape their gender identities in their everyday life.

Persistent Organic Pollutants (POPs) are toxic organic compounds resistant to environmental degradation. Besides, POPs bioaccumulation with potential significant impacts on human health and the environment. The Global Monitoring Plan (GMP) under the Stockholm Convention on POPs is a program that enables collection of comparable monitoring data from all regions of the world to assess the effectiveness in minimizing human and environmental exposure to POPs. The scope of this work is to develop and validate a method for the extraction and determination of POPs in sediments collected at Billings dam locate in São Paulo Metropolitan City. The compounds studied in this work are: Aldrin (C{sub 12}H{sub 8}C{sub l6}), DDD (C{sub 14}H{sub 10}C{sub l4}), DDE (C{sub 14}H{sub 8}Cl{sub l4)}, DDT (C{sub 14}H{sub 9}C{sub l5}), Dieldrin (C{sub 12}H{sub 8}C{sub l6}O), Endrin (C{sub 12}H{sub 8}Cl{sub 6}O) and Heptachlor (C{sub 10}H{sub 5}C{sub l7}). This work use the QuEChERS extraction method (Quick, Easy, Cheap, Effective, Rugged, and Safe) for sediment samples and the analysis of the compounds were carried out by gas chromatography with the electron capture detector (GC/ECD). The ECD detector ionizes the analytes by the beta particles from the nuclide sources {sup 63}Ni within carrier gas N{sub 2}. The electrons produced in this process are collected, create an amplified current, and generating the chromatographic peak. The recovery of this method obtained values between 57% and 65% and the Relative Standard Deviation (RSD) values are between 1 and 4%. Details of the analytical method beside quantitative analyses data are presented in this work. (author)

The impacts of emission trends of POPs on human concentration dynamics: Lessons learned from a longitudinal study in Norway (1979-2007).

In this short communication, our focus is on the relationship between human concentrations of select persistent organic pollutants (POPs) and environmental emissions. It is based on a longitudinal study (1979-2007) conducted in Norway. Our aim was to extract general insights from observed and predicted temporal trends in human concentrations of 49 POPs to assist in the design and interpretation of future monitoring studies. Despite considerable decline for polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) since 1986, the sum of the targeted POPs increased from 1979 until 2001, with per- and polyfluorinated alkyl substances (PFASs) dominating recent blood burden measurements. Specifically, the time trends in serum concentrations of POPs, exemplified by PCB-153, 1,1'-(2,2,2-Trichloroethane-1,1-diyl)bis(4-chlorobenzene) (DDT) and perfluorooctane sulfonic acid (PFOS), resembled the trends in available data on their emissions, production or use. These observations suggest that interpretations of human biomonitoring data on persistent compounds must consider historic emissions, which likely vary spatially across the globe. Based on the different temporal trends observed across POP groups, it is evident that generalizations regarding temporal aspects have limitations. The discussion herein underscores the importance of understanding temporal variations in environmental emissions when designing and interpreting human biomonitoring studies.

Full Text Available A first long-term monitoring of selected persistent organic pollutants (POPs in Antarctic air has been conducted at the Norwegian research station Troll (Dronning Maud Land. As target contaminants 32 PCB congeners, α- and γ-hexachlorocyclohexane (HCH, trans- and cis-chlordane, trans- and cis-nonachlor, p,p'- and o,p-DDT, DDD, DDE as well as hexachlorobenzene (HCB were selected. The monitoring program with weekly samples taken during the period 2007–2010 was coordinated with the parallel program at the Norwegian Arctic monitoring site (Zeppelin mountain, Ny-Ålesund, Svalbard in terms of priority compounds, sampling schedule as well as analytical methods. The POP concentration levels found in Antarctica were considerably lower than Arctic atmospheric background concentrations. Similar to observations for Arctic samples, HCB is the predominant POP compound, with levels of around 22 pg m−3 throughout the entire monitoring period. In general, the following concentration distribution was found for the Troll samples analyzed: HCB > Sum HCH > Sum PCB > Sum DDT > Sum chlordanes. Atmospheric long-range transport was identified as a major contamination source for POPs in Antarctic environments. Several long-range transport events with elevated levels of pesticides and/or compounds with industrial sources were identified based on retroplume calculations with a Lagrangian particle dispersion model (FLEXPART.

2014-04-01

Full Text Available Persistent Organic Pollutants (POPs have been restricted and prohibited at national level for several decades now and since the 21st century at international level under the Stockholm Convention and the Convention of Long-Range Transboundary Air Pollution (LRTAP. A high mountain lake sediment core was sampled in the Alps (Gossenköllesee in summer 2010 and analyzed on POPs to examine whether the expected decreasing trends due to the implementation of the international Conventions could be observed. Higher POPs concentrations were observed in the sections corresponding to the period of large scale production and usage. p,p’-DDE and p,p’-DDD showed maximum concentrations in the core sections corresponding to the 1970s. These concentrations decreased to more or less constant levels in the top sediments, which is in agreement with the timing of past usage and banning of this pesticide. On the other hand, PCBs and HCB peaked in 1980s and the concentrations fluctuated afterwards. These observed profiles suggest that the studied site is still under influence of primary or secondary emissions and that the regulations of the international Conventions have still not been noticed in this site.

Current Status and Regulatory Aspects of Pesticides Considered to be Persistent Organic Pollutants (POPs in Taiwan

Directory of Open Access Journals (Sweden)

Wen-Tien Tsai

2010-10-01

Full Text Available Organochlorine pesticides (OCPs are capable of persisting in the environment, transporting between phase media and accumulating to high levels, implying that they could pose a risk of causing adverse effects to human health and the environment. Consequently, most OCPs are designated as persistent organic pollutants (POPs and even as endocrine disrupting chemicals (EDCs. The objective of this paper was to review the current status of pesticide POPs in Taiwan, including aldrin, chlordane, chlordecone, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene, α/β-hexachlorocyclohexanes, lindane, mirex, pentachloro-benzene, and toxaphene. The information about their environmental properties, banned use, carcinogenic toxicity and environmental levels, can be connected with the regulatory infrastructure, which has been established by the joint-venture of the central competent authorities (i.e., Environmental Protection Administration, Department of Health, Council of Agriculture, and Council of Labor Affairs. The significant progress to be reported is that the residual levels of these pesticide-POPs, ranging from trace amounts to a few ppb, have declined notably in recent years.

Current issues and uncertainties in the measurement and modelling of air-vegetation exchange and within-plant processing of POPs

International Nuclear Information System (INIS)

Barber, Jonathan L.; Thomas, Gareth O.; Kerstiens, Gerhard; Jones, Kevin

2004-01-01

Air-vegetation exchange of POPs is an important process controlling the entry of POPs into terrestrial food chains, and may also have a significant effect on the global movement of these compounds. Many factors affect the air-vegetation transfer including: the physicochemical properties of the compounds of interest; environmental factors such as temperature, wind speed, humidity and light conditions; and plant characteristics such as functional type, leaf surface area, cuticular structure, and leaf longevity. The purpose of this review is to quantify the effects these differences might have on air/plant exchange of POPs, and to point out the major gaps in the knowledge of this subject that require further research. Uptake mechanisms are complicated, with the role of each factor in controlling partitioning, fate and behaviour process still not fully understood. Consequently, current models of air-vegetation exchange do not incorporate variability in these factors, with the exception of temperature. These models instead rely on using average values for a number of environmental factors (e.g. plant lipid content, surface area), ignoring the large variations in these values. The available models suggest that boundary layer conductance is of key importance in the uptake of POPs, although large uncertainties in the cuticular pathway prevents confirmation of this with any degree of certainty, and experimental data seems to show plant-side resistance to be important. Models are usually based on the assumption that POP uptake occurs through the lipophilic cuticle which covers aerial surfaces of plants. However, some authors have recently attached greater importance to the stomatal route of entry into the leaf for gas phase compounds. There is a need for greater mechanistic understanding of air-plant exchange and the 'scaling' of factors affecting it. The review also suggests a number of key variables that researchers should measure in their experiments to allow comparisons

2007-02-01

Full Text Available The enhanced Polar Outflow Probe (ePOP is scheduled to be launched as part of the Cascade Demonstrator Small-Sat and Ionospheric Polar Explorer (CASSIOPE satellite in early 2008. A Radio Receiver Instrument (RRI on ePOP will receive HF transmissions from various ground-based transmitters. In preparation for the ePOP mission, data from a similar transionospheric experiment performed by the International Satellites for Ionospheric Studies (ISIS II satellite has been studied. Prominent features in the received 9.303-MHz signal were periodic Faraday fading of signal intensity at rates up to 13 Hz and a time of arrival delay between the O- and X-modes of up to 0.8 ms. Both features occurred when the satellite was above or south of the Ottawa transmitter. Ionospheric models for ray tracing were constructed using both International Reference Ionosphere (IRI profiles and local peak electron density values from ISIS ionograms. Values for fade rate and differential mode delay were computed and compared to the values observed in the ISIS II data. The computed values showed very good agreement to the observed values of both received signal parameters when the topside sounding foF2 values were used to scale IRI profiles, but not when strictly modelled IRI profiles were used. It was determined that the primary modifier of the received signal parameters was the foF2 density and not the shape of the profile. This dependence was due to refraction, at the 9.303-MHz signal frequency, causing the rays to travel larger distances near the peak density where essentially all the mode splitting occurred. This study should assist in interpretation of ePOP RRI data when they are available.

Full Text Available We describe bayesPop, an R package for producing probabilistic population projections for all countries. This uses probabilistic projections of total fertility and life expectancy generated by Bayesian hierarchical models. It produces a sample from the joint posterior predictive distribution of future age- and sex-specific population counts, fertility rates and mortality rates, as well as future numbers of births and deaths. It provides graphical ways of summarizing this information, including trajectory plots and various kinds of probabilistic population pyramids. An expression language is introduced which allows the user to produce the predictive distribution of a wide variety of derived population quantities, such as the median age or the old age dependency ratio. The package produces aggregated projections for sets of countries, such as UN regions or trading blocs. The methodology has been used by the United Nations to produce their most recent official population projections for all countries, published in the World Population Prospects.

Modelling atmospheric transport of persistent organic pollutants in the Northern Hemisphere with a 3-D dynamical model: DEHM-POP

Science.gov (United States)

Hansen, K. M.; Christensen, J. H.; Brandt, J.; Frohn, L. M.; Geels, C.

2004-03-01

The Danish Eulerian Hemispheric Model (DEHM) is a 3-D dynamical atmospheric transport model originally developed to describe the atmospheric transport of sulphur into the Arctic. A new version of the model, DEHM-POP, developed to study the atmospheric transport and environmental fate of persistent organic pollutants (POPs) is presented. During environmental cycling, POPs can be deposited and re-emitted several times before reaching a final destination. A description of the exchange processes between the land/ocean surfaces and the atmosphere is included in the model to account for this multi-hop transport. The α-isomer of the pesticide hexachlorocyclohexane (α-HCH) is used as tracer in the model development. The structure of the model and processes included are described in detail. The results from a model simulation showing the atmospheric transport for the years 1991 to 1998 are presented and evaluated against measurements. The annual averaged atmospheric concentration of α-HCH for the 1990s is well described by the model; however, the shorter-term average concentration for most of the stations is not well captured. This indicates that the present simple surface description needs to be refined to get a better description of the air-surface exchange proceses of POPs.

CO2 Conversion: The Potential of Porous–Organic Polymers (POPs) for the cycloaddition of CO2 and epoxides

Novel porous organic polymers (POPs) have been synthesized using functionalized Cr and Co-salen complexes as molecular building blocks. The integration of metalosalen catalysts into the porous polymers backbone permits the successful utilization of the materials as solid-state catalysts for CO2-epoxide cycloadditions reactions with excellent catalytic performance under mild conditions of temperature and pressure. The catalyst proved to be fully recyclable and robust thus showing the potential of POPs as smart functional materials for the heterogenization of key catalytic elements.

Ecotoxicology of organochlorine chemicals in birds of the Great Lakes

2013-01-01

Silent Spring was fulfilled in the United States with passage of environmental legislation such as the Clean Water Act, the Federal Insecticide, Fungicide, and Rodenticide Act, and the Toxic Substance Control Act in the 1970s. Carson's writings, television interviews, and testimony before Congress alerted a nation and the world to the unintended effects of persistent, bioaccumulative chemicals on populations of fish, wildlife, and possibly humans. Her writings in the popular press brought attention to scientific findings that declines in populations of a variety of birds were directly linked to the widespread use of dichlorodiphenyltrichloroethane (DDT) in agriculture, public health, and horticulture. By the 1970s, DDT and other persistent organic pollutants (POPs) were being banned or phased out, and the intent of these regulatory acts became apparent in a number of locations across the United States, including the Great Lakes. Concentrations of DDT and its major product of transformation, dichlorodiphenylchloroethane (DDE), were decreasing in top predators, such as bald eagles (Haliaeetus leucocephalus), osprey (Pandion haliaetus), colonial waterbirds, and other fish-eating wildlife. Eggshell thinning and the associated mortality of bird embryos caused by DDE had decreased in the Great Lakes and elsewhere by the early 1980s.

A comparison of POPs bioaccumulation in Eisenia fetida in natural and artificial soils and the effects of aging.

Vlčková, Klára; Hofman, Jakub

2012-01-01

The close relationship between soil organic matter and the bioavailability of POPs in soils suggests the possibility of using it for the extrapolation between different soils. The aim of this study was to prove that TOC content is not a single factor affecting the bioavailability of POPs and that TOC based extrapolation might be incorrect, especially when comparing natural and artificial soils. Three natural soils with increasing TOC and three artificial soils with TOC comparable to these natural soils were spiked with phenanthrene, pyrene, lindane, p,p'-DDT, and PCB 153 and studied after 0, 14, 28, and 56 days. At each sampling point, total soil concentration and bioaccumulation in earthworms Eisenia fetida were measured. The results showed different behavior and bioavailability of POPs in natural and artificial soils and apparent effects of aging on these differences. Hence, direct TOC based extrapolation between various soils seems to be limited. Copyright © 2011 Elsevier Ltd. All rights reserved.

Unveiling CO2 heterogeneous freezing plumes during champagne cork popping.

Liger-Belair, Gérard; Cordier, Daniel; Honvault, Jacques; Cilindre, Clara

2017-09-14

Cork popping from clear transparent bottles of champagne stored at different temperatures (namely, 6, 12, and 20 °C) was filmed through high-speed video imaging in the visible light spectrum. During the cork popping process, a plume mainly composed of gaseous CO 2 with traces of water vapour freely expands out of the bottleneck through ambient air. Most interestingly, for the bottles stored at 20 °C, the characteristic grey-white cloud of fog classically observed above the bottlenecks of champagne stored at lower temperatures simply disappeared. It is replaced by a more evanescent plume, surprisingly blue, starting from the bottleneck. We suggest that heterogeneous freezing of CO 2 occurs on ice water clusters homogeneously nucleated in the bottlenecks, depending on the saturation ratio experienced by gas-phase CO 2 after adiabatic expansion (indeed highly bottle temperature dependent). Moreover, and as observed for the bottles stored at 20 °C, we show that the freezing of only a small portion of all the available CO 2 is able to pump the energy released through adiabatic expansion, thus completely inhibiting the condensation of water vapour found in air packages adjacent to the gas volume gushing out of the bottleneck.

Possible emissions of POPs in plain and hilly areas of Nepal: Implications for source apportionment and health risk assessment.

Ambient air is a core media chosen for monitoring under the Stockholm Convention on POPs. While extensive monitoring of POPs in ambient air has been carried out in some parts of the globe, there are still regions with very limited information available, such as some developing countries as Nepal. This study therefore aims to target the occurrence of selected POPs in Nepal in suspected source areas/more densely populated regions. Four potential source regions in Nepal were furthermore targeted as it was hypothesized that urban areas at lower altitudes (Birgunj and Biratnagar located at approximately 86 and 80 m.a.s.l.) would be potentially more affected by OCPs because of more intensive agricultural activities in comparison to urban areas at higher altitudes (Kathmandu, Pokhara located 1400 and 1135 m.a.s.l). As some of these areas could also be impacted by LRAT, air mass back trajectories during the sampling period were additionally evaluated using HYSPLIT. The concentrations of overall POPs were twice as high in plain areas in comparison to hilly areas. DDTs and HCHs were most frequently detected in the air samples. The high p,p'-DDT/(pp'-DDE + pp'-DDD) ratio as well as the low o,p'-DDT/p,p'-DDT ratio observed in this study was inferred as continuing use of technical DDT. High levels of ∑ 26 PCBs were linked to proximity to highly urbanized and industrial areas, indicating the potential source of PCBs. The measured concentrations of legacy POPs in air from this study is assumed to represent a negligible health risk through inhalation of ambient air, however, other modes of human exposure could still be relevant in Nepal. The air mass backward trajectory analysis revealed that most of the air masses sampled originated from India and the Bay of Bengal. Copyright © 2016 Elsevier Ltd. All rights reserved.

Persistent organic pollutants (POPs) are toxic substances, highly resistant to environmental degradation, which can bio-accumulate and have long-range atmospheric transport potential. Most studies focus on single compound effects, however as humans are exposed to several POPs simultaneously, investigating exposure effects of real life POP mixtures on human health is necessary. A defined mixture of POPs was used, where the compound concentration reflected its contribution to the levels seen in Scandinavian human serum (total mix). Several sub mixtures representing different classes of POPs were also constructed.

Persistent organic pollutants (POPs) are toxic substances, highly resistant to environmental degradation, which can bio-accumulate and have long-range atmospheric transport potential. Most studies focus on single compound effects, however as humans are exposed to several POPs simultaneously, investigating exposure effects of real life POP mixtures on human health is necessary. A defined mixture of POPs was used, where the compound concentration reflected its contribution to the levels seen in Scandinavian human serum (total mix). Several sub mixtures representing different classes of POPs were also constructed. The perfluorinated (PFC) mixture contained six perfluorinated compounds, brominated (Br) mixture contained seven brominated compounds, chlorinated (Cl) mixture contained polychlorinated biphenyls and also p,p’-dichlorodiphenyldichloroethylene, hexachlorobenzene, three chlordanes, three hexachlorocyclohexanes and dieldrin.

Full Text Available Refletir fãs no cenário atual traz à tona uma visão antropológica de uma experiência estética que parece destacar a nostalgia dos consumidores da narrativa do ídolo. Neste trabalho, partimos da hipótese de que é a nostalgia um dos principais elos que mantém um fandom de música pop através da narrativa de seu ídolo no palco e fora dele. Propomos uma análise do show-fixo, que aqui chamamos de “monumento”, o “Piece of Me”, no qual a performer Britney Spears rememora momentos de sua carreira no teatro do Planet Hollywood em Las Vegas fazendo uso de dublagem em todo o show e artefatos corporais para simular sua aparência e voz de outrora numa cidade quase fantasma. Questionamos, então, como se dá a construção narrativa do espaço de pertencimento na música pop capaz de gerar nostalgia através dos conceitos de utopia e heterotopia (Foucault, a noção de “lar” (Boym.

Innovation technique of radiation for the treatment of 4-chlorphenol as a model of POPs in waste water

The pollution becomes more serious with the development of economy in China especially for waste water, among which 80% comes from industries. The absence of fresh water has large limitation to the development of China now. Because it will bring the most harmful results to environment and health of people, the degradation of POPs is very important. Radiation is one of the effective methods for mineralization of POPs as most of their compounds are derivatives of phenyl ring. However, the costs of equipment and operation are too high to use for irradiation. It should be supposed that breakage of benzene ring of POPs at lower irradiated dosage (below 20 kGy) in developed radiation processing turns into organic acids and other compounds, which could be removed by micro-organisms easily. It means that after irradiation organic materials can be treated by the use of biological method. It is obvious that integration of different processing could both use the advantage of breaking phenyl ring under lower dosage and overcome the disadvantage of reducing the TOC at very high dosage by use of irradiation. In this paper, the radiolytical mechanism of 4-chlorphenol as a model of POPs has been studied by the use of pulse radiolysis and analysis of stable products irradiated in different conditions. It has been shown that 4-chlorphenol can be turned into organic acids effectively in basic aqueous solution saturated with oxygen under lower irradiated dosages

Retrogressive harmonic motion as structural and stylistic characteristic of pop-rock music

Science.gov (United States)

Carter, Paul S.

The central issue addressed in this dissertation is that of progressive and retrogressive harmonic motion as it is utilized in the repertoire of pop-rock music. I believe that analysis in these terms may prove to be a valuable tool for the understanding of the structure, style and perception of this music. Throughout my study of this music, various patterns of progressive and retrogressive harmonic motions within a piece reveal a kind of musical character about it, a character on which much of a work's style, organization and extramusical nature often depends. Several influential theorists, especially Jean-Phillipe Rameau, Hugo Riemann, and Arnold Schoenberg, have addressed the issues of functional harmony and the nature of the motion between chords of a tonal harmonic space. After assessing these views, I have found that it is possible to differentiate between two fundamental types of harmonic motions. This difference, one that I believe is instrumental in characterizing pop-rock music, is the basis for the analytical perspective I wish to embrace. After establishing a method of evaluating tonal harmonic root motions in these terms, I wish to examine a corpus of this music in order to discover what a characterization of its harmonic motion may reveal about each piece. Determining this harmonic character may help to establish structural and stylistic traits for that piece, its genre, composer, period, or even its sociological purpose. Conclusions may then be drawn regarding the role these patterns play in defining musical style traits of pop-rock. Partly as a tool for serving the study mentioned above I develop a graphical method of accounting for root motion I name the tonal "Space-Plot"; This apparatus allows the analyst to measure several facets about the harmonic motion of the music, and to see a wide scope of relations in and around a diatonic key.

Full Text Available Pop songs are, in fact, an ideal source for incidental vocabulary learning because teenagers often spend large amounts of their free time listening to music and in particular to pop songs. Employing an experimental approach, this study attempted to investigate the role of pop songs on vocabulary recall, attitude and retention of Iranian advanced adult EFL learners based on their gender. In so doing a language placement test (Quick Oxford Placement Test was administered to 100 male and female language learners studying English at different language institutes in Esfahan, Iran. Ultimately, 60 advanced learners (30 males - 30 females were selected by leaving out the students of other levels of proficiency and randomly divided into two relatively homogenous groups as musical and non-musical groups. While the students of musical group (=30 were taught the new vocabulary in the syllabus through 60 different pop songs chosen by themselves through a questionnaire, the students of the non-musical group (n=30 were taught new vocabulary without using the songs. The participants were examined based on an English vocabulary test developed by the researchers, which probed into the learners’ vocabulary recall. A questionnaire was also used to investigate the attitude of the learners towards the instruction. A month later the vocabulary test was re-administered as a delayed retention test and obtained data were statistically analyzed. The results of t-tests demonstrated that the musical group outscored the non-musical group on vocabulary recall and retention. The results also showed the male learners perform better than the females. Keywords: incidental vocabulary, pop songs, vocabulary recall, attitude, retention

GENRE IN RELATION TO SACRUM. CRISIS OF FAITH, HORROR AND POP CULTURE

2010-01-01

Full Text Available In the text “Genre in relation to sacrum. Crisis of faith, horror and pop culture” Samuel Nowak and Anna Taszycka ponder over the phenomenon of modern horror raising the subject of sacrum, especially in relation to the motive of possession and exorcism. The authors attempt to prove that the phenomenon is symptomatic for the transition from religiousness, understood in institutional and collective terms, to individual and contemplative spirituality. After analysing selected films from the perspective of “spirituality” (in the meaning given to it by Zbigniew Pasek the authors conclude that today the pop cultural narrations which depict the new function of sacrum and shift the load from institution to an individual may become successful and accepted by viewers.According to the authors the traditional narration – which associates sacrum with a religious experience – is supplanted today by stories which treat sacrum rather in terms of a spiritual experience. This transformation leads to many possible alternative interpretations of selected films which in this text were described in categories of pensiveness or meta-interpretation.

Full Text Available The development and the transformations of the Popular Culture - at first expression of the rise of the capitalist middle class, then of the markets and customs’ globalization and of the technological and virtual progress – have been phenomena that have caused anthropologic revolutions in the social contexts. The increasing individualism, the commodification of the human relationships, the virtualization of everyday life, the alienation, the homologation, the breakdown of the community and institutional ties, the pervasive role of television and Internet, the empty hedonism which takes the place of the existential and ideal engagement: there are many issues that the humanities have to face. As it is already the case of the philosophy, the debate on the urgency of a pedagogy that, alongside the traditional one, can connote itself as “pop”, has been recently entered into the scene of the pedagogical discussion. The “pop pedagogy” reflects on popular culture and doesn’t skimp to use pop tools, languages and sources.

The subject of this study is the bonus system adopted in New York City to create privately owned spaces for public use, known as POPS (Privately Owned Public Spaces. Based on Jan Gehl’s theoretical principles, a quantitative and qualitative survey on Park Avenue was carried out. The analysis of the collected data showed that buildings’ corporate plazas not only contribute to public use of free spaces but also ennoble the urban landscape of the area. Yet, people’s effective use of these open public spaces still depend on the degree of accessibility and visual permeability between the POPS and the public circulation areas, the sidewalks.

Erasmus of Rotterdam (1466-1536): renaissance advocate of the public role of medicine.

Albury, W R; Weisz, G M

2003-08-01

The great Renaissance scholar Erasmus of Rotterdam was a pioneering advocate of the importance of medicine for social as well as individual welfare. Erasmus' "Oration in praise of the art of medicine" (1518) illustrates his literary approach to this topic. Although the original version of his text did not address the state's role in promoting the health of the populace, Erasmus inserted new material on this topic into the "Oration" for a 1529 edition. This new material and references in some of his other writings from the same period indicate that it was in the 1520s that Erasmus first became a strong advocate of government intervention in public health matters. It is suggested that medical events in Erasmus' own life-his experiences both as a patient and as an observer of diseases-may explain why his interest in public health legislation increased significantly around this time.

To investigate the correlation between pelvic organ prolapse quantitation (POP-Q) indication points and the incidence of occult stress urinary incontinence (OSUI) and its impact on prognosis. Retrospective study medical records of 93 patients with pelvic organ prolapse (POP) staged at III-IV, of which underwent pelvic reconstruction operations with Prolift system from Jan. 2007 to Sept. 2012. None of these patients had clinical manifestations of stress urinary incontinence (SUI) before surgery, and in which 44 patients were included in study group (POP complicated with OSUI) because they were identified with OSUI, another 49 patients as control group (simple POP). Follow-up and collecting datas including POP-Q, stress test, urodynamic recordings, incidence of de novo SUI, statistic analyzing by logistic regression and receiver operating characteristic curve (ROC). (1) The study group had a much higher incidence of 30% (13/44) on de novo SUI than that of control group (4%, 2/49; P < 0.01). (2) Vaginal delivery (OR = 5.327, 95% CI: 1.120-25.347), constipation (OR = 5.789, 95% CI: 1.492-22.459), preoperative OSUI (OR = 13.695, 95% CI: 2.980-62.944), anterior vaginal wall prolapse (OR = 6.115, 95% CI: 1.231-30.379) were identified as dependent risk factors for de novo SUI by logistic regression analysis. (3) For POP patients that complicated with OSUI, we chose a cutoff value of +1.5 cm for Aa point as the threshold to predicting incidence of de novo SUI according to ROC curve, area under the curve (AUC) was 0.889 (P < 0.05), the sensitivity reached 88.9% and specificity was 73.9%. According to ROC curve of Ba point, a cutoff value of +2.5 cm was chosen as the threshold to predicting incidence of de novo SUI post-operation, it had a sensitivity of 66.7% and specificity of 82.6%, AUC was 0.766 (P < 0.05). Pre-operative OSUI is a dependent risk factor of de novo SUI for advanced POP patients. Aa and Ba points are correlated with preoperative OSUI, and it is worthy to be

Population health decision makers must consider complex relationships between multiple concepts measured with differential accuracy from heterogeneous data sources. Population health information systems are currently limited in their ability to integrate data and present a coherent portrait of population health. Consequentially, these systems can provide only basic support for decision makers. The Population Health Record (PopHR) is a semantic web application that automates the integration and extraction of massive amounts of heterogeneous data from multiple distributed sources (e.g., administrative data, clinical records, and survey responses) to support the measurement and monitoring of population health and health system performance for a defined population. The design of the PopHR draws on the theories of the determinants of health and evidence-based public health to harmonize and explicitly link information about a population with evidence about the epidemiology and control of chronic diseases. Organizing information in this manner and linking it explicitly to evidence is expected to improve decision making related to the planning, implementation, and evaluation of population health and health system interventions. In this paper, we describe the PopHR platform and discuss the architecture, design, key modules, and its implementation and use. © 2016 New York Academy of Sciences.

We report in situ polarimetry measurements of HF scattering obtained by the Enhanced Polar Outflow Probe (e-POP) Radio Receiver Instrument (RRI) during a coherent backscatter scattering event detected by the Saskatoon Super Dual Auroral Radar Network (SuperDARN). On April 1, 2015, e-POP conducted a 4 minute coordinated experiment with SuperDARN Saskatoon, starting at 3:38:44 UT (21:38:44 LT). Throughout the experiment, SuperDARN was transmitting at 17.5 MHz and e-POP's ground track moved in a northeastward direction, along SuperDARN's field-of-view, increasing in altitude from 331 to 352 km. RRI was tuned to 17.505 MHz, and recorded nearly 12,000 SuperDARN radar pulses during the experiment. In the first half of the experiment, radar pulses recorded by RRI were "well behaved": they retained their transmitted amplitude envelope, and their pulse-to-pulse polarization characteristics were coherent - Faraday rotation was easily measured. During the second half of the experiment the pulses showed clear signs of scattering: their amplitude envelopes became degraded and dispersed, and their pulse-to-pulse polarization characteristics became incoherent - Faraday rotation was difficult to quantify. While these pulses were being received by RRI, SuperDARN Saskatoon detected a latitudinal band of coherent backscatter at e-POP's location, indicating that the scattered pulses measured by RRI may be a signature of HF backscatter. In this presentation, we will outline the polarimetric details of the scattered pulses, and provide an analytic interpretation of RRI's measurements to give new insight into the nature of HF coherent backscatter mechanism taking place in the terrestrial ionosphere.

The occurrence of persistent organic pollutants (POPs) in the environment can affect organisms inhabiting aquatic systems, in particular shallow lakes that are vulnerable to environmental stressors. This study aimed to assess POPs accumulation and changes at histological and physiological levels in tissues of three fish species with different trophic habits. Gills, brain, muscle, liver and gonads of Odontesthes bonariensis, Oligosarcus jenynsii and Cyphocharax voga were collected from the shallow lake La Peregrina, located in an agricultural area from Argentina. In addition, contaminant levels in surface water (SW), suspended particulate matter (SPM) and bottom sediments (BS) were assessed. Histological lesions were evaluated in fish tissues and levels of vitellogenin (VTG) were assessed in plasma of male fish in order to correlate these alterations with the presence of POPs in the environment. Organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) were determined by GC-ECD. Biotic and abiotic samples showed the same POPs distribution pattern: OCPs>PCBs>PBDEs. Although tissue distribution of OCPs was species-specific, muscle showed the lowest levels in all species. The most abundant contaminants were endosulfans, suggesting their widespread use in the area. O. bonariensis showed the highest endosulfans levels in liver (184.2-219ngg(-1)wet w), which was associated with the high SPM levels considering this species is a filter feeder. The occurrence of PCBs and PBDEs shows the ubiquity of these pollutants in the area. Histological lesions in gills and liver of O. bonariensis and O. jenynsii, might be related with the high levels of endosulfans in these organs. The detection of VTG in males warns about a possible exposure to estrogenic compounds in the environment. In conclusion, the simultaneous exposure of fish to multiple environmental pollutants leads to different alterations, so measures should be taken in

Positional priming of pop-out is nested in visuospatial context.

2013-11-26

The present study investigated facilitatory and inhibitory positional priming using a variant of Maljkovic and Nakayama's (1996) priming of pop-out task. Here, the singleton target and the distractors could be presented in different visuospatial contexts-but identical screen locations-across trials, permitting positional priming based on individual locations to be disentangled from priming based on interitem configural relations. The results revealed both significant facilitatory priming, i.e., faster reaction times (RTs) to target presented at previous target relative to previously empty locations, and inhibitory priming, i.e., slower RTs to target at previous distractor relative to previously empty locations. However, both effects were contingent on repetitions versus changes of stimulus arrangement: While facilitation of target locations was dependent on the repetition of the exact item configuration (e.g., T-type followed by T-type stimulus arrangement), the inhibitory effect was more "tolerant," being influenced by repetitions versus changes of the item's visuospatial category (T-type followed by Z-type pattern; cf. Garner & Clement, 1963). The results suggest that facilitatory and inhibitory priming are distinct phenomena (Finke et al., 2009) and that both effects are sensitive to subtle information about the arrangement of the display items (Geyer, Zehetleitner, & Müller, 2010). The results are discussed with respect to the stage(s) of visual pop-out search that are influenced by positional priming.

Full Text Available Objective. The purpose of this pilot study was to determine whether Super Pop VR, a low-cost virtual reality (VR system, was a feasible system for documenting improvement in children with cerebral palsy (CP and whether a home-based VR intervention was effective. Methods. Three children with CP participated in this study and received an 8-week VR intervention (30 minutes × 5 sessions/week using the commercial EyeToy Play VR system. Reaching kinematics measured by Super Pop VR and two fine motor tools (Bruininks-Oseretsky Test of Motor Proficiency second edition, BOT-2, and Pediatric Motor Activity Log, PMAL were tested before, mid, and after intervention. Results. All children successfully completed the evaluations using the Super Pop VR system at home where 85% of the reaches collected were used to compute reaching kinematics, which is compatible with literature using expensive motion analysis systems. Only the child with hemiplegic CP and more impaired arm function improved the reaching kinematics and functional use of the affected hand after intervention. Conclusion. Super Pop VR proved to be a feasible evaluation tool in children with CP.

Full Text Available Passive air samplers (PAS were deployed at 86 European background sites during summer 2006 in order (i to gain further insight into spatial patterns of persistent organic pollutants (POPs in European background air and, (ii to evaluate PAS as an alternative sampling technique under EMEP (Co-operative programme for monitoring and evaluation of the long-range transmissions of air pollutants in Europe. The samples were analyzed for selected PCBs, HCHs, DDTs, HCB, PAHs and chlordanes, and air concentrations were calculated on the basis of losses of performance reference compounds. Air concentrations of PCBs were generally lowest in more remote areas of northern Europe with elevated levels in more densely populated areas. γ-HCH was found at elevated levels in more central parts of Europe, whereas α-HCH, β-HCH and DDTs showed higher concentrations in the south-eastern part. There was no clear spatial pattern in the concentrations for PAHs, indicative of influence by local sources, rather than long range atmospheric transport (LRAT. HCB was evenly distributed across Europe, while the concentrations of chlordanes were typically low or non-detectable. A comparison of results obtained on the basis of PAS and active air sampling (AAS illustrated that coordinated PAS campaigns have the potential serve as useful inter-comparison exercises within and across existing monitoring networks. The results also highlighted limitations of the current EMEP measurement network with respect to spatial coverage. We finally adopted an existing Lagrangian transport model (FLEXPART as recently modified to incorporate key processes relevant for POPs to evaluate potential source regions affecting observed concentrations at selected sites. Using PCB-28 as an example, the model predicted concentrations which agreed within a factor of 3 with PAS measurements for all except 1 out of the 17 sites selected for this analysis.

Alinhados com a revolução comportamental, com as ideias do feminismo e com a postura iconoclasta da juventude da época, os ambientes pop propunham novas formas de mediação entre as pessoas e os artefatos que contribuíram na transformação dos esquemas corporais associados às representações de feminilidades.In this article, we bring to the fore some changes of women corporal practices that we have identified through the analysis of models of domesticity we found on issues of the popular magazine Casa & Jardim, printed from the end of the 1960s to the mid 1970s. We want to emphasize the appropriation of Pop language in the decoration of Brazilian domestic interiors as one of the facets of youth culture, which diffused internationally during the 1960s. Aligned with feminist ideas, revolutions of behaviors, and iconoclast attitudes of the youth of the time, Pop spaces have embodied new forms of mediation among people and artifacts and also have contributed to the transformation of corporal schemata, indeed associated with the representations of femininity.

The Balloon Popping Problem Revisited: Lower and Upper Bounds

Science.gov (United States)

Jung, Hyunwoo; Chwa, Kyung-Yong

We consider the balloon popping problem introduced by Immorlica et al. in 2007 [13]. This problem is directly related to the problem of profit maximization in online auctions, where an auctioneer is selling a collection of identical items to anonymous unit-demand bidders. The auctioneer has the full knowledge of bidders’ private valuations for the items and tries to maximize his profit. Compared with the profit of fixed price schemes, the competitive ratio of Immorlica et al.’s algorithm was in the range [1.64, 4.33]. In this paper, we narrow the gap to [1.659, 2].

Jennings, Aaron A; Li, Zijian

2015-09-01

Surface soil contamination is a worldwide problem. Many regulatory jurisdictions attempt to control human exposures with regulatory guidance values (RGVs) that specify a soil's maximum allowable concentration. Pesticides are important soil contaminants because of their intentional toxicity and widespread surface soil application. Worldwide, at least 174 regulatory jurisdictions from 54 United Nations member states have published more than 19,400 pesticide RGVs for at least 739 chemically unique pesticides. This manuscript examines the variability of the guidance values that are applied worldwide to the original 2001 Stockholm Convention persistent organic pollutants (POP) pesticides (Aldrin, Chlordane, DDT, Dieldrin, Endrin, Heptachlor, Mirex, and Toxaphene) for which at least 1667 RGVs have been promulgated. Results indicate that the spans of the RGVs applied to each of these pesticides vary from 6.1 orders of magnitude for Toxaphene to 10.0 orders of magnitude for Mirex. The distribution of values across these value spans resembles the distribution of lognormal random variables, but also contain non-random value clusters. Approximately 40% of all the POP RGVs fall within uncertainty bounds computed from the U.S. Environmental Protection Agency (USEPA) RGV cancer risk model. Another 22% of the values fall within uncertainty bounds computed from the USEPA's non-cancer risk model, but the cancer risk calculations yield the binding (lowest) value for all POP pesticides except Endrin. The results presented emphasize the continued need to rationalize the RGVs applied worldwide to important soil contaminants. Copyright © 2015 Elsevier Ltd. All rights reserved.

diminished its meaning to that “of an average or poor culture”, whereas it most probably indicates quite the contrary, as it reflects the widespread but prosaic synonym imbutus litteris. In addition, the word tinctus seems to allude to Lucretius – a poet (well known by Cicero that often uses tingo – and constitutes a positive and refined colour metaphor. In summary, the orator tinctus litteris, little appreciated by Antonius but still welcomed at his school, seems to be the portrait of the young Cicero, who really had been his student, a literate scholar committed for life to the ennoblement of the oratory style to a greater extent than his masters.

Physical inactivity is a known risk factor for obesity and a number of chronic diseases. Modifying the physical features of neighborhoods to provide residents with equitable and convenient access to spaces for physical activity (PA) is a promising strategy for promoting PA. Public urban recreation spaces (e.g., parks) play an important role in promoting PA and are potentially an important neighborhood element for optimizing social capital and liveability in cities. Most studies examining the effects of park availability and use on PA have focused on traditional, permanent parks. The aims of this study were to (1) document patterns of park use and park-based PA at a temporary urban pop-up park implemented in the downtown business district of Los Altos, California during July-August 2013 and May-June 2014, (2) identify factors associated with park-based PA in 2014, and (3) examine the effects of the 2014 pop-up park on additional outcomes of potential benefit for park users and the Los Altos community at large. Park use remained high during most hours of the day in 2013 and 2014. Although the park attracted a multigenerational group of users, children and adolescents were most likely to engage in walking or more vigorous PA at the park. Park presence was significantly associated with potentially beneficial changes in time-allocation patterns among users, including a reduction in screen-time and an increase in overall park-time and time spent outdoors. Park implementation resulted in notable use among people who would otherwise not be spending time at a park (85% of surveyed users would not be spending time at any other park if the pop-up park was not there-2014 data analysis). Our results (significantly higher odds of spending time in downtown Los Altos due to park presence) suggest that urban pop-up parks may also have broader community benefits, such as attracting people to visit downtown business districts. Pending larger, confirmatory studies, our results suggest

On Populist Pop Culture: Ethno as the Contemporary Political Ideology in Serbia

2016-12-01

Full Text Available This study attempts to shift the debate of the contemporary facets of populist ideologies from the realm of institutional politics to the realm of everyday life, popular culture, media and “invented traditions”. My intention is to demonstrate how these realms generate new sources and voices of populism, often downplayed in the academic debates on the subject. The paper stems from comprehensive research on discourses of identity (reconstruction in post-Yugoslav Serbia as communicated in pop-cultural media forms (specifically, music videos of all genres, in which I used a sample of 4733 music videos produced between 1980 and 2010 (and later. In this paper, I have chosen to focus on the case of the charity campaign Podignimo Stupove and its music video output. The campaign was launched as a pop-cultural initiative to help the restoration of the 12th century monastery Đurđevi Stupovi in Stari Ras, a site of utmost historical significance and value for the national culture. Against the background of institutional changes that markedly redefined the place of religion in Serbian post-socialist society, the music videos discussed in this paper provide a valuable insight into the combined musical, textual and visual language of communication of some longstanding notions associated with “Serbian populism”.

RNase MRP RNA and RNase P activity in plants are associated with a Pop1p containing complex.

Krehan, Mario; Heubeck, Christian; Menzel, Nicolas; Seibel, Peter; Schön, Astrid

2012-09-01

RNase P processes the 5'-end of tRNAs. An essential catalytic RNA has been demonstrated in Bacteria, Archaea and the nuclei of most eukaryotes; an organism-specific number of proteins complement the holoenzyme. Nuclear RNase P from yeast and humans is well understood and contains an RNA, similar to the sister enzyme RNase MRP. In contrast, no protein subunits have yet been identified in the plant enzymes, and the presence of a nucleic acid in RNase P is still enigmatic. We have thus set out to identify and characterize the subunits of these enzymes in two plant model systems. Expression of the two known Arabidopsis MRP RNA genes in vivo was verified. The first wheat MRP RNA sequences are presented, leading to improved structure models for plant MRP RNAs. A novel mRNA encoding the central RNase P/MRP protein Pop1p was identified in Arabidopsis, suggesting the expression of distinct protein variants from this gene in vivo. Pop1p-specific antibodies precipitate RNase P activity and MRP RNAs from wheat extracts. Our results provide evidence that in plants, Pop1p is associated with MRP RNAs and with the catalytic subunit of RNase P, either separately or in a single large complex.

Screening-level exposure-based prioritization to identify potential POPs, vPvBs and planetary boundary threats among Arctic contaminants

2017-06-01

Full Text Available A report that reviews Arctic contaminants that are not currently regulated as persistent organic pollutants (POPs under international treaties was recently published by the Arctic Monitoring and Assessment Programme (AMAP. We evaluated 464 individual chemicals mentioned in the AMAP report according to hazard profiles for POPs, very persistent and very bioaccumulative (vPvB chemicals, and two novel and distinct hazard profiles we derived from the planetary boundary threat framework. The two planetary boundary threat profiles assign high priority to chemicals that will be mobile and poorly reversible environmental contaminants. Utilizing persistence as a proxy for poor reversibility, we defined two exposure-based hazard profiles; airborne persistent contaminants (APCs and waterborne persistent contaminants (WPCs that are potential planetary boundary threats. We used in silico estimates of physicochemical properties and multimedia models to calculate hazard metrics for persistence, bioaccumulation and long-range transport potential, then we synthesized this information into four exposure-based hazard scores of the potential of each AMAP chemical to fit each of the POP, vPvB, APC and WPC exposure-based hazard profiles. As an alternative to adopting a “bright line” score that represented cause for concern, we scored the AMAP chemicals by benchmarking against a reference set of 148 known and relatively well-studied contaminants and expressed their exposure-based hazard scores as percentile ranks against the scores of the reference set chemicals. Our results show that scores in the four exposure-based hazard profiles provide complementary information about the potential environmental exposure-based hazards of the AMAP chemicals. Our POP, vPvB, APC and WPC exposure-based hazard scores identify high priority chemicals for further study from among the AMAP contaminants.

ULTRA-LOW AMPLITUDE VARIABLES IN THE LARGE MAGELLANIC CLOUD-CLASSICAL CEPHEIDS, POP. II CEPHEIDS, RV TAU STARS, AND BINARY VARIABLES

International Nuclear Information System (INIS)

Robert Buchler, J.; Wood, Peter R.; Soszynski, Igor

2009-01-01

A search for variable stars with ultra-low amplitudes (ULAs), in the millimagnitude range, has been made in the combined MACHO and OGLE databases in the broad vicinity of the Cepheid instability strip in the HR diagram. A total of 25 singly periodic and 4 multiply periodic ULA objects have been uncovered. Our analysis does not allow us to distinguish between pulsational and ellipsoidal (binary) variabilities, nor between Large Magellanic Cloud (LMC) and foreground objects. However, the objects are strongly clustered and appear to be associated with the pulsational instability strips of LMC Pop. I and II variables. When combined with the ULA variables of Buchler et al., a total of 20 objects fall close to the classical Cepheid instability strip. However, they appear to fall on parallel period-magnitude (PM) relations that are shifted to slightly higher magnitude which would confer them a different evolutionary status. Low-amplitude RV Tauri and Pop. II Cepheids have been uncovered that do not appear in the MACHO or OGLE catalogs. Interestingly, a set of binaries seem to lie on a PM relation that is essentially parallel to that of the RV Tauri/Pop. II Cepheids.

2015-01-01

Infertility remains a significant problem for many couples. Approximately one in seven couples who attempt to conceive will fail to do so within 1 year. In about 65% of these cases, there is a male component of infertility.1 Despite normal semen parameters, the etiology of infertility remains uncertain in more than 50% of couples.2 Defects in sperm proteins and/ or structures may underlie certain cases of male infertility. Although many men would like to be called "Pop", "Dad", or "Papa", those who are classified with idiopathic male infertility have few options for becoming fathers. Recent studies by Aarabi et al.3 may open the door to new therapies.

POP load and vitamins as potential biomarkers in the Baltic seals

Exceptionally high levels of polychlorinated biphenyls (PCB) and 1,1,1.trichloro- 2,2-bis[p-chlorophenyl]ethane (DDT) and its metabolites were reported in the Baltic seals in the late 1960s and early 1970s. PCB levels in ringed seals, in particular, are still high enough to threaten the well being of the animals. The observed difference in contaminant pattern between ringed and grey seals in the Baltic has not been explained, but could be partly due to species-specific food sources. Several pathological and biochemical changes observed in the Baltic seals correlate with the individual POP loads. Of the observed biochemical changes, elevated cytochrome P4501A (CYP1A) levels, decreased liver vitamin A stores and increased vitamin E levels in blubber or plasma, have been proposed as possible biomarkers of contaminant load in Baltic seals. However, as the vitamin A and E status of marine mammals also reflects the nutritional vitamin level, the lower vitamin A and elevated vitamin E levels observed in the Baltic seals could be a reflection of the levels of these vitamins in their food sources. The aim of this study was to investigate the contaminant load in the Baltic seals and to evaluate the utility level of potential exposure and effect biomarkers. Seals from less contaminated areas were used as reference material (Svalbard and Sable Island, Canada). In the present study, POP and vitamin levels were also studied in seal prey species in order to study the transfer of these compounds to grey and ringed seals from their main food sources.

Conclusion: Better viewing efficiency was observed in younger individuals compared to older individuals. Difficulty in disregarding irrelevant stimuli and thereby resorting to inefficient search strategy is proposed as the reason for the differences. The finding that both older and younger individuals are not affected significantly by the presence of the irrelevant pop out distracter has implications in situations such as driving or hazard avoidance. In such scenarios, search performance is likely not impaired beyond what is found with distracters (visual clutter in the environment.

The role of Hallyu as pop culture in the creation and dissemination of the contemporary korean woman's image

Directory of Open Access Journals (Sweden)

Nayelli López Rocha

2016-02-01

Full Text Available Categorized as a cultural phenomenon by its international scope and for being a diffuser and disseminator element of Korean culture during the last decade, this movement without precedents called "Hallyu" or "Korean wave" has been instrumental in the promotion and dissemination of Korea’s image in many countries around the world. Due to the importance that this cultural flow has achieved in the past ten years, its definition has been taking and integrating, during its development process, different characteristics. Nowadays, K-pop or pop music has become the most popular element contained within the called Korean pop culture that, in turn, becomes the country’s image to other latitudes. In this work the Hallyu is defined as a socio-cultural phenomenon of hybrid characteristics which contains elements of Korean traditional and modern culture, as elements of the socalled global culture, mixing it in a peculiar way in the local context redefining it as authentically Korean. This project specifically explores how, through Hallyu, the image of modern Korean woman has been modeled by certain characteristics, reaffirming an idea of women which do not necessarily represent the majority of them in this country. In this way, it is analyzed; the construction of the image of Korean women in its current society to understand in which circumstances this image of contemporary woman is created and recreated, establishing an image of being woman to recipients of Hallyu.

Elevance of PCDD/PCDF formation for the evaluation of POPs destruction technologies. PCB destruction over a TiO2-based V2O5-WO3 catalyst

Energy Technology Data Exchange (ETDEWEB)

Weber, R. [Tuebingen Univ. (Germany)

2004-09-15

PCDDs/PCDFs and PCBs in off-gas from municipal waste incinerators. At higher temperatures, the catalyst can also be used for POPs (and VOC) destruction. In this respect Hagenmaier investigated different oxidation catalysts for PCB destruction efficiency and found superior destruction properties for the TiO2-based V{sub 2}O{sub 5}-WO{sub 3} catalyst. PCB destruction exhibits a special challenge because they are PCDF precursors and n easily be oxidised into the more toxic PCDFs. Therefore, the formation of PCDDs/PCDFs during destruction of PCBs (POPs) is one important criterion for the evaluation of a PCB (POPs) destruction technology. The relevance of PCDF formation during destruction of PCBs was demonstrated e.g. for the supercritical water oxidation technology (SCWO), a technology listed in the highest rank of non-combustion technologies from the United Nations Environmental Programme (UNEP) and the United Nations Industrial Development Organization (UNIDO), where PCDFs were formed in the %-range. Therefore the present study evaluates the relevance of PCDF formation during catalytic destruction of PCBs on a TiO{sub 2}-based V{sub 2}O{sub 5}-WO{sub 3} catalyst. The study aims to give an example of how an assessment of PCDF formation as a function of operation conditions for PCB (POPs) destruction might be performed for the evaluation of a PCB (POPs) destruction technology. Further, the results demonstrate that for the catalytic oxidation over TiO{sub 2}-based V{sub 2}O{sub 5}-WO{sub 3} catalyst, the problem of PCDF formation can be overcome.

The project MONARPOP analysed the concentrations of semivolatile organic compounds (SVOCs) in two important sink compartments, needles of Norway spruce (Picea abies [L.] Karst.) and forest soil from 40 remote Alpine forest sites in Austria, Germany, Italy, Slovenia and Switzerland. In the present study the load of PCDD/F, PCB, PBDE, PAH, HCB, HCH and DDT in the Alps calculated on the basis of measured data are compared with their estimated emissions in the Alpine region. It comes out that the masses of the studied pollutants stored in the forests are higher than the corresponding emissions in the Alpine area indicating that the Alps are a sink for POPs advected from surrounding areas. It is assumed that local emissions of PCDD/F and PAH deriving from biomass burning are probably underestimated and that the pool of these pollutants in the forests represents the accumulation over some decades. - The loads of POPs in the Alps are higher than their emissions in the Alpine region.

Exploring the benefit of synaesthetic colours: testing for "pop-out" in individuals with grapheme-colour synaesthesia.

Science.gov (United States)

Rich, Anina N; Karstoft, Karen-Inge

2013-01-01

In grapheme-colour synaesthesia, letters, numbers, and words elicit involuntary colour experiences. Recently, there has been much emphasis on individual differences and possible subcategories of synaesthetes with different underlying mechanisms. In particular, there are claims that for some, synaesthesia occurs prior to attention and awareness of the inducing stimulus. We first characterized our sample using two versions of the "Synaesthetic Congruency Task" to distinguish "projector" and "associator" synaesthetes who may differ in the extent to which their synaesthesia depends on attention and awareness. We then used a novel modification of the "Embedded Figures Task" that included a set-size manipulation to look for evidence of preattentive "pop-out" from synaesthetic colours, at both a group and an individual level. We replicate an advantage for synaesthetes over nonsynaesthetic controls on the Embedded Figures Task in accuracy, but find no support for pop-out of synaesthetic colours. We conclude that grapheme-colour synaesthetes are fundamentally similar in their visual processing to the general population, with the source of their unusual conscious colour experiences occurring late in the cognitive hierarchy.

Sequencing of microbial genomes is important because of microbial-carrying antibiotic and pathogenetic activities. However, even with the help of new assembling software, finishing a whole genome is a time-consuming task. In most bacteria, pathogenetic or antibiotic genes are carried in genomic islands. Therefore, a quick genomic island (GI) prediction method is useful for ongoing sequencing genomes. In this work, we built a Web server called GI-POP (http://gipop.life.nthu.edu.tw) which integrates a sequence assembling tool, a functional annotation pipeline, and a high-performance GI predicting module, in a support vector machine (SVM)-based method called genomic island genomic profile scanning (GI-GPS). The draft genomes of the ongoing genome projects in contigs or scaffolds can be submitted to our Web server, and it provides the functional annotation and highly probable GI-predicting results. GI-POP is a comprehensive annotation Web server designed for ongoing genome project analysis. Researchers can perform annotation and obtain pre-analytic information include possible GIs, coding/non-coding sequences and functional analysis from their draft genomes. This pre-analytic system can provide useful information for finishing a genome sequencing project. Copyright © 2012 Elsevier B.V. All rights reserved.

Effects of irradiation on fungi and fumonisin B(1) in corn, and of microwave-popping on fumonisins in popcorn.

Science.gov (United States)

D'Ovidio, K L; Trucksess, M W; Devries, J W; Bean, G

2007-07-01

Fumonisins are metabolites produced in corn primarily by the fungus Fusarium verticillioides (F. moniliforme) and are toxic to humans and animals. Fumonisin B(1) (FB(1)) is the primary fumonisin produced and is found frequently in corn kernels, some of which may be used as food or food ingredients. A three-part study was conducted to determine the effects of gamma- and electron beam irradiation on the levels of fumonisins in naturally contaminated field corn, and the effects of microwave-popping on fumonisins in selected, naturally contaminated popcorn. To date, no effective means have been found to reduce consistently mycotoxin levels once foods are contaminated. Aqueous solutions of FB(1) at various concentrations, samples of whole corn, and samples of ground corn containing known levels of FB(1) were irradiated with various levels of cobalt and electron beam irradiation. Popcorn samples, taken from the reject streams of popcorn processing, were popped using normal microwave-popping conditions. FB(1) in aqueous solutions was reduced by 99.7% using a minimal level of irradiation (0.5 kGray). Gamma- and electron beam irradiation did not significantly reduce levels of FB(1) in whole and ground corn. Aspergillus sp., Penicillium sp. and Fusarium sp. fungi were totally eliminated at 30 kGray in ground corn and at 100 kGray in whole corn. The normal commercial cleaning processes for microwave popcorn before packaging reduced fumonisins to fumonisins resulted in significant reduction of the mould toxin.

The voice is apparently used in quite different manners in different styles of singing. Some of these differences concern the voice source, which varies considerably with loudness, pitch, and mode of phonation. We attempt to describe voice source differences between Classical, Pop, Jazz and Blues styles of singing as produced in a triad melody pattern by a professional female singer in soft, middle and loud phonation. An expert panel was asked to identify these triads as examples of either Classical, Pop, Jazz or Blues. The voice source was analysed by inverse filtering. Subglottal pressure Ps, closed quotient QClosed, glottal compliance (ratio between the air volume contained in a voice pulse and Ps), and the level difference between the two lowest source spectrum partials were analysed in the styles and in four modes of phonation: breathy, flow, neutral, and pressed. The same expert panel rated the degree of pressedness in the entire material. Averages across pitch were calculated for each mode and style and related to their total range of variation in the subject. The glottogram data showed a high correlation with the ratings of pressedness. Based on these correlations a pressedness factor was computed from the glottogram data. A phonation map was constructed with the axes representing mean adduction factor and mean Ps, respectively. In this map Classical was similar to flow phonation, Pop and Jazz to neutral and flow phonation, and Blues to pressed phonation.

Persistent environmental pollutants, including heavy metals and persistent organic pollutants (POPs), have a ubiquitous presence. Many of these pollutants affect neurobiological processes, either accidentally or by design. The aim of this study was to explore the associations between assayed measures of POPs and heavy metals and depressive symptoms. We hypothesised that higher levels of pollutants and metals would be associated with depressive symptoms. National Health and Nutrition Examination Survey (NHANES). A total of 15 140 eligible people were included across the three examined waves of NHANES. Depressive symptoms were assessed using the nine-item version of the Patient Health Questionnaire (PHQ-9), using a cut-off point of 9/10 as likely depression cases. Organic pollutants and heavy metals, including cadmium, lead and mercury, as well as polyfluorinated compounds (PFCs), pesticides, phenols and phthalates, were measured in blood or urine. Higher cadmium was positively associated with depression (adjusted Prevalence Ratios (PR)=1.48, 95% CI 1.16 to 1.90). Higher levels of mercury were negatively associated with depression (adjusted PR=0.62, 95% CI 0.50 to 0.78), and mercury was associated with increased fish consumption (n=5500, r=0.366, p<0.001). In addition, several PFCs (perfluorooctanoic acid, perfluorohexane sulfonic acid, perfluorodecanoic acid and perfluorononanoic acid) were negatively associated with the prevalence of depression. Cadmium was associated with an increased likelihood of depression. Contrary to hypotheses, many of persistent environmental pollutants were not associated or negatively associated with depression. While the inverse association between mercury and depressive symptoms may be explained by a protective role for fish consumption, the negative associations with other pollutants remains unclear. This exploratory study suggests the need for further investigation of the role of various agents and classes of agents in the

especially in music and video clips? To address this archetype, we start from the Brazilian figure pombagira, symbol of a free, wild, sensual and sexual female strength. According to the theory of Warburg (2012, strong symbols reappear in the art due to the recurring nature of pathos, which he calls Pathosformel. We will show, with the study of three female figures of the star system media how a free female, although it has been ravaged by centuries of phallocentrism, is resurfacing and manifesting in pop culture.

Determination of toxicity of complex mixtures has been proposed to be one of the most important challenges for modern toxicology. In this study we performed genome wide transcriptome profiling to assess potential toxicant induced changes in gene regulation in zebrafish embryos following parental exposure to two natural mixtures of persistent organic pollutants (POPs). The mixtures used were extracted from burbot (Lota lota) liver originating from two lakes (Lake Mjøsa and Lake Losna) belonging to the same freshwater system in Norway. The dominating groups of contaminants were polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs) and dichlorodiphenyltrichloroethane metabolites (DDTs). Because both mixtures used in the present study induced similar effects, it is likely that the same toxicants are involved. The Mjøsa mixture contains high levels of PBDEs while this group of pollutants is low in the Losna mixture. However, both mixtures contain substantial concentrations of PCB and DDT suggesting these contaminants as the predominant contributors to the toxicity observed. The observed effects included phenotypic traits, like embryo production and survival, and gene transcription changes corresponding with disease and biological functions such as cancer, reproductive system disease, cardiovascular disease, lipid and protein metabolism, small molecule biochemistry and cell cycle. The changes in gene transcription included genes regulated by HNF4A, insulin, LH, FSH and NF-κB which are known to be central regulators of endocrine signaling, metabolism, metabolic homeostasis, immune functions, cancer development and reproduction. The results suggest that relative low concentrations of the natural mixtures of POPs used in the present study might pose a threat to wild freshwater fish living in the lakes from which the POPs mixtures originated.

Kazakhstan is included in the list of environmentally vulnerable countries and Kyzylorda oblast in particular. This is due to its geographical, spatial and temporal and socioeconomic features. As part of the program "Integrated approaches in the management of public health in the Aral region", we have carried out an expertise on many samples of natural environments and products. Samples were selected in accordance with sampling procedures according to regulatory documents by specialists of the Pesticide Toxicology Laboratory. It is accredited by the State Standard of the Republic of Kazakhstan, for compliance with ST RK ISO/IEC 17025-2007 "General requirements for the competence of test and calibration laboratories". Gas chromatograph was used for the determination of residues of organochlorine pesticides. For the determination of dioxins, polychlorinated biphenyl was conducted on the gas chromatomass spectrometer with quadruple detector produce by Agilent Company, USA. To assess the risk, we carried out the mathematical calculations according to the risk of chemicals polluting (No P 2.1.10.1920-04, Russia). Calculation of the carcinogenic risk was carried out with the use of data on the size of the exposure and meanings of carcinogenic potential factors (slope factor and unit risk). The evaluation of persistent organic pollutants (POPs), based on the previous results of the research concerning water, soil and food products, was held in five population settlements in Kyzylorda oblast villages: Ayteke bi, Zhalagash, Zhosaly, Shieli and Aralsk town. Pollution with the POPs in the environmental objects by means of exposition and evaluation of the carcinogenic risk to human health is confirmed by the data of the statistical reporting about some morbidity in Kyzylorda oblast, such as skin diseases and subcutaneous tissue, endocrine system diseases, pregnancy complications etc. The received levels of carcinogenic risks, which were first carried out in the Republic of

Creativity, alcohol and drug abuse: the pop icon Jim Morrison.

2014-01-01

Alcohol and drug abuse is frequent among performers and pop musicians. Many of them hope that alcohol and drugs will enhance their creativity. Scientific studies are scarce and conclusions limited for methodological reasons. Furthermore, extraordinary creativity can hardly be grasped by empirical-statistical methods. Thus, ideographic studies are necessary to learn from extraordinarily creative persons about the relationship of creativity with alcohol and drugs. The pop icon Jim Morrison can serve as an exemplary case to investigate the interrelation between alcohol and drug abuse and creativity. Morrison's self-assessments in his works and letters as well as the descriptions by others are analyzed under the perspective of creativity research. In the lyrics of Jim Morrison and in biographical descriptions, we can see how Jim Morrison tried to cope with traumatic events, depressive moods and uncontrolled impulses through creative activities. His talent, skill and motivation to write creatively were independent from taking alcohol and drugs. He used alcohol and drugs to transgress restrictive social norms, to broaden his perceptions and to reinforce his struggle for self-actualization. In short, his motivation to create something new and authentic was reinforced by alcohol and drugs. More important was the influence of a supportive group that enabled Morrison's talents to flourish. However, soon the frequent use of high doses of alcohol and drugs weakened his capacity to realize creative motivation. Jim Morrison is an exemplary case showing that heavy drinking and the abuse of LSD, mescaline and amphetamines damages the capacity to realize creative motivation. Jim Morrison is typical of creative personalities like Amy Winehouse, Janis Joplin, Brian Jones and Jimmy Hendrix who burn their creativity in early adulthood through alcohol and drugs. We suppose that the sacrificial ritual of their decay offers some benefits for the excited spectators. One of these is the

Listening to loud music may be connected to addictive behavior possibly leading to damaging effects on the cochlea. We hypothesized that members of non-professional pop/rock bands with regular exposure to loud music are more likely to show an addictive-like behavior for loud music than matched control subjects. Fifty non-professional musicians and 50 matched control subjects were asked to complete the Northeastern Music Listening Survey (NEMLS) with two basic components. The first comprises an adaptation of the validated Michigan Alcohol Screening Test (MAST) to study the addictive-like behavior towards loud music. The second comprises the criteria outlined by the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) of the American Psychiatric Society for the diagnosis of substance dependence. The NEMLS was scored using the same point system as used in the MAST. The DSM-IV criteria for substance dependence were met by nine of the musician group and by one control subject. Seven of these nine musicians also had a positive NEMLS score. Traits of addictive-like behavior to loud music were detected more often in members of nonprofessional pop/rock bands than in control subjects.

Full Text Available For modelling the spatial distribution of malaria incidence, accurate and detailed information on population size and distribution are of significant importance. Different, global, spatial, standard datasets of population distribution have been developed and are widely used. However, most of them are not up-to-date and the low spatial resolution of the input census data has limitations for contemporary, national- scale analyses. The AfriPop project, launched in July 2009, was initiated with the aim of producing detailed, contemporary and easily updatable population distribution datasets for the whole of Africa. High-resolution satellite sensors can help to further improve this dataset through the generation of high-resolution settlement layers at greater spatial details. In the present study, the settlement extents included in the MALAREO land use classification were used to generate an enhanced and updated version of the AfriPop dataset for the study area covering southern Mozambique, eastern Swaziland and the malarious part of KwaZulu-Natal in South Africa. Results show that it is possible to easily produce a detailed and updated population distribution dataset applying the AfriPop modelling approach with the use of high-resolution settlement layers and population growth rates. The 2007 and 2011 population datasets are freely available as a product of the MALAREO project and can be downloaded from the project website.

Association of Dioxin and Other Persistent Organic Pollutants (POPs) with Diabetes: Epidemiological Evidence and New Mechanisms of Beta Cell Dysfunction

Science.gov (United States)

De Tata, Vincenzo

2014-01-01

The worldwide explosion of the rates of diabetes and other metabolic diseases in the last few decades cannot be fully explained only by changes in the prevalence of classical lifestyle-related risk factors, such as physical inactivity and poor diet. For this reason, it has been recently proposed that other “nontraditional” risk factors could contribute to the diabetes epidemics. In particular, an increasing number of reports indicate that chronic exposure to and accumulation of a low concentration of environmental pollutants (especially the so-called persistent organic pollutants (POPs)) within the body might be associated with diabetogenesis. In this review, the epidemiological evidence suggesting a relationship between dioxin and other POPs exposure and diabetes incidence will be summarized, and some recent developments on the possible underlying mechanisms, with particular reference to dioxin, will be presented and discussed.

It helps to accelerate the predominance of cultural production as a construct agent both of meaning and of entertainment. A visual sequencing that allows an intense perception of a message in a very short period of time. From the phenomena related to the audiovisual production of women artists I will reflect on the performative force of the musical videos of pop divas and the drifts that can become in the social and political demands that occur in them. First, the role of subjectivation in the production and consumption of them. Second, the processes of socialization and performativity that articulate other social imaginaries for women and men and establish a different order in gender discourses. So how they contribute to changes in the production of culture, being also aware of mixed interests in a cultural mainstream environment.

Suitable reverberation time for halls for rock and pop music

The existing body of literature regarding the acoustic design of concert halls has focused almost exclusively on classical music, although there are many more performances of popular music, including rock and pop. Objective measurements were made of the acoustics of 20 rock music venues in Denmark....... The best-rated halls in the study have reverberation times that are approximately frequency independent from 0.6 to 1.2 s for hall volumes from 1000 to 6000 m3. The worst rated halls in the study had significantly higher reverberation times in the 63 and 125 Hz bands. Since most audiences at rock concerts...... are standing, absorption coefficients were measured with a standing audience from 63 Hz to 4 kHz. These measurements showed that a standing audience absorbs about five times as much energy in mid-/high-frequency bands as in low-frequency bands....

Exploring the benefit of synaesthetic colours: Testing for “pop-out” in individuals with grapheme–colour synaesthesia

Science.gov (United States)

Rich, Anina N.; Karstoft, Karen-Inge

2013-01-01

In grapheme–colour synaesthesia, letters, numbers, and words elicit involuntary colour experiences. Recently, there has been much emphasis on individual differences and possible subcategories of synaesthetes with different underlying mechanisms. In particular, there are claims that for some, synaesthesia occurs prior to attention and awareness of the inducing stimulus. We first characterized our sample using two versions of the “Synaesthetic Congruency Task” to distinguish “projector” and “associator” synaesthetes who may differ in the extent to which their synaesthesia depends on attention and awareness. We then used a novel modification of the “Embedded Figures Task” that included a set-size manipulation to look for evidence of preattentive “pop-out” from synaesthetic colours, at both a group and an individual level. We replicate an advantage for synaesthetes over nonsynaesthetic controls on the Embedded Figures Task in accuracy, but find no support for pop-out of synaesthetic colours. We conclude that grapheme–colour synaesthetes are fundamentally similar in their visual processing to the general population, with the source of their unusual conscious colour experiences occurring late in the cognitive hierarchy.

A review of current knowledge and future prospects regarding persistent organic pollutants over the Tibetan Plateau.

Wang, Xiaoping; Gong, Ping; Wang, Chuanfei; Ren, Jiao; Yao, Tandong

2016-12-15

Since the turn of the century, our understanding of the quantities, transport pathways, and fate of persistent organic pollutants (POPs) over the Tibetan Plateau (TP), the largest and highest plateau on Earth, has greatly enhanced. We begin in this article by reviewing the available literature on the levels of POPs over the TP. In general, the levels of most POPs are similar or lower than values reported for other background regions. However, dichlorodiphenyltrichloroethane (DDT) and hexachlorocyclohexane (HCH) levels in air and soil far exceed those measured in other mountainous areas. The East Asian monsoon, Indian Monsoon and westerly winds are responsible for the long-range atmospheric transport (LRAT) and arrival of POPs over the TP. Surface soil and vegetation act as "final sinks" for DDTs and other high molecular weight POPs. Linked to the continuous use of POPs in surrounding counties, LRAT and "cold trapping" by the TP can happen following emission-transport-deposition events, leading to the enrichment of POPs in the TP environment. Bioaccumulation of DDTs and high chlorinated PCBs have been found in Tibetan terrestrial and aquatic food chains, and newly emerging compounds such as polyfluoroalkyl substances and hexabromocyclododecanes have been widely detected in wild fish species. The corresponding ecological risks should be of great concern. Climate change, such as increased temperatures and changing coverage of snow and glaciers, has the potential to affect the behavior and distribution of POPs. Therefore, long-term monitoring data are required. Ineffective regulation regarding POPs has been reported for countries in South Asia, emissions patterns, the outflow of POPs, and their seasonal and inter-annual variability should therefore be clarified. Estimating the loading of POPs, as well as how they move, within the TP, especially under the impact of glacial melt and global warming, should be a priority. Copyright © 2016.

In 1926-1927, a graduate student, B. C. Graves, working with Stanford University psychologist Walter Miles and legendary football coach Pop Warner, conducted an investigation of variations in signal calling as they affected the charging times of football players. The study was one of two that involved Miles and the ingenious multiple chronograph that he had invented to time the reactions of seven players simultaneously. These studies represented a brief digression in the career of Miles, who certainly was no sport psychologist. They tell of an interesting collaboration between scientist and coaches that produced one of the richest studies in sport psychology in the first half of the twentieth century.

PopPlanner: Visually constructing demographic models for simulation

Directory of Open Access Journals (Sweden)

Gregory Bruce Ewing

2015-04-01

Full Text Available Currently there are a number of coalescent simulation programs that support a wide range of features, such as arbitrary demographic models, migration, and sub structure. Defining the model is done typically with either text files or command line switches. Although this has proven to be a powerful method of defining models of high complexity, it is often error prone and difficult to read without familiarity both with command lines and the program in question. A intuitive GUI based population structure program that can both read and write applicable command lines would dramatically simplify the construction, modification, and error checking of such models by a wider user base.Results: PopPlanner is a tool to both construct and inspect complicated demographic models visually with a GUI where the user’s primary interaction is through mouse gestures. Because of their popularity, we focus on ms and by extension msms, command line coalescent simulation programs. Our program can be used to find errors with existing command lines, or to build original command lines. Furthermore the graphical output supports a number of editing and output features including export of publication quality figures.

Facilitating responsible gambling: the relative effectiveness of education-based animation and monetary limit setting pop-up messages among electronic gaming machine players.

Wohl, Michael J A; Gainsbury, Sally; Stewart, Melissa J; Sztainert, Travis

2013-12-01

Although most gamblers set a monetary limit on their play, many exceed this limit--an antecedent of problematic gambling. Responsible gambling tools may assist players to gamble within their means. Historically, however, the impact of such tools has been assessed in isolation. In the current research, two responsible gambling tools that target adherence to a monetary limit were assessed among 72 electronic gaming machine (EGM) players. Participants watched an educational animation explaining how EGMs work (or a neutral video) and then played an EGM in a virtual reality environment. All participants were asked to set a monetary limit on their play, but only half were reminded when that limit was reached. Results showed that both the animation and pop-up limit reminder helped gamblers stay within their preset monetary limit; however, an interaction qualified these main effects. Among participants who did not experience the pop-up reminder, those who watched the animation stayed within their preset monetary limits more than those who did not watch the animation. For those who were reminded of their limit, however, there was no difference in limit adherence between those who watched the animation and those who did not watch the animation. From a responsible gambling perspective, the current study suggests that there is no additive effect of exposure to both responsible gambling tools. Therefore, for minimal disruption in play, a pop-up message reminding gamblers of their preset monetary limit might be preferred over the lengthier educational animation.

Investigating the occurrence of persistent organic pollutants (POPs) in the arctic: their atmospheric behaviour and interaction with the seasonal snow pack

International Nuclear Information System (INIS)

Halsall, Crispin J.

2004-01-01

POPs in the Arctic are the focus of international concern due to their occurrence and accumulation in Arctic food webs. This paper presents an overview of the major pathways into the Arctic and details contemporary studies that have focused on the occurrence and transfer of POPs between the major Arctic compartments, highlighting areas where there is a lack of quantitative information. The behaviour of these chemicals in the Arctic atmosphere is scrutinised with respect to long-term trends and seasonal behaviour. Subtle differences between the PCBs and OC pesticides are demonstrated and related to sources outside of the Arctic as well as environmental processes within the Arctic. Unlike temperate regions, contaminant fate is strongly affected by the presence of snow and ice. A description of the high Arctic snow pack is given and the physical characteristics that determine chemical fate, namely the specific surface area of snow and wind driven ventilation, are discussed. Using a well-characterised fresh snow event observed at Alert (Canadian high Arctic) [Atmos. Environ. 36(2002) 2767] the flux of γ-HCH out of the snow is predicted following snow ageing. Under conditions of wind (10 m/s) it is estimated that ∼75% of the chemical may be re-emitted to the atmosphere within 24 h following snowfall, compared with just ∼5% under conditions of no wind. The implications of this are raised and areas of further research suggested. - The fluxes and fate of POPs in snowpacks are key to their behaviour in polar systems

Temporal trends of persistent organic pollutants (POPs) in arctic foxes (Vulpes lagopus) from Svalbard, Norway, were investigated in relation to feeding habits and seasonal food availability. Arctic foxes from Svalbard forage in both marine and terrestrial ecosystems and the availability of their food items are impacted by climatic variability. Concentrations of polychlorinated biphenyls (PCBs), organochlorinated pesticides (OCPs) and brominated flame retardants (polybrominated diphenyl ethers [PBDEs] and hexabromocyclododecane [HBCDD]) were analyzed in the liver of 141 arctic foxes collected between 1997 and 2013. Stable carbon isotope values (δ{sup 13}C) were used as a proxy for feeding on marine versus terrestrial prey. The annual number of recovered reindeer carcasses and sea ice cover were used as proxies for climate influenced food availability (reindeers, seals). Linear models revealed that concentrations of PCBs, chlordanes, p,p′-DDE, mirex and PBDEs decreased 4–11% per year, while no trends were observed for hexachlorobenzene (HCB) or β-hexachlorocyclohexane (β-HCH). Positive relationships between POP concentrations and δ{sup 13}C indicate that concentrations of all compounds increase with increasing marine dietary input. Increasing reindeer mortality was related to lower HCB concentrations in the foxes based on the linear models. This suggests that concentrations of HCB in arctic foxes may be influenced by high mortality levels of Svalbard reindeer. Further, β-HCH concentrations showed a positive association with sea ice cover. These results in addition to the strong effect of δ{sup 13}C on all POP concentrations suggest that climate-related changes in arctic fox diet are likely to influence contaminant concentrations in arctic foxes from Svalbard. - Highlights: • POPs were analyzed in the arctic foxes' liver (n = 141) from Svalbard collected in 1997–2013. • PCBs, chlordanes, p,p′-DDE, mirex and PBDEs decreased 4–11% per year. �

Full Text Available Recent advances in DNA sequencing have enabled mapping of genes for monogenic traits in families with small pedigrees and even in unrelated cases. We report the identification of disease-causing mutations in a rare, severe, skeletal dysplasia, studying a family of two healthy unrelated parents and two affected children using whole-exome sequencing. The two affected daughters have clinical and radiographic features suggestive of anauxetic dysplasia (OMIM 607095, a rare form of dwarfism caused by mutations of RMRP. However, mutations of RMRP were excluded in this family by direct sequencing. Our studies identified two novel compound heterozygous loss-of-function mutations in POP1, which encodes a core component of the RNase mitochondrial RNA processing (RNase MRP complex that directly interacts with the RMRP RNA domains that are affected in anauxetic dysplasia. We demonstrate that these mutations impair the integrity and activity of this complex and that they impair cell proliferation, providing likely molecular and cellular mechanisms by which POP1 mutations cause this severe skeletal dysplasia.

Scouting the Desert of the Real: Avant-Gardism of the Avant-Pop

2010-05-01

Full Text Available The paper examines the legacy of the European historical Avant-Gardes from the perspective of the shift of paradigms immanent in the formation of the Postmodern epoch. The existing theories generally regard the Avant-Gardes as an unsuccessful attempt to redefine the function of art in the social, cultural and economic environment of the early 20th century. Examining the productivity and relevance of the historical Avant-Gardes from the perspective of the Avant-Pop, the first thoroughly Postmodern literary movement, I intend to show how the strategies of fragmentation and the breaking of organicity not only quintessentially defined the manner in which Modernity and its art came to an end, but how they also provided the basis forthe formation of culture and art that no longer functions according to Cartesian principles.

2011-01-01

The power supply system for the magnets of the CERN PS has been recently upgraded to a new system called POPS (POwer for PS). The old mechanical machine has been replaced by a system based on capacitors. The equipments as well as the low level controls have been provided by an external company (CONVERTEAM). The supervision application has been developed at CERN reusing the technologies and tools used for the LHC Accelerator and Experiments (UNICOS and JCOP frameworks, SIMATIC WinCC Open Architecture SCADA tool). The paper describes the full architecture of the control application, and the challenges faced for the integration with an outsourced system. The benefits of reusing the CERN industrial control frameworks and the required adaptations will be discussed. Finally, the initial operational experience will be presented.

Dictator Perpetuus: Julius Caesar--did he have seizures? If so, what was the etiology?

Science.gov (United States)

Hughes, John R

2004-10-01

The "Dictator Perpetuus" of the Roman Empire, the great Julius Caesar, was not the one for whom the well-known cesarean operation was named; instead, this term is derived from a Latin word meaning "to cut." Caesar likely had epilepsy on the basis of four attacks that were probably complex partial seizures: (1) while listening to an oration by Cicero, (2) in the Senate while being offered the Emperor's Crown, and in military campaigns, (3) near Thapsus (North Africa) and (4) Corduba (Spain). Also, it is possible that he had absence attacks as a child and as a teenager. His son, Caesarion, by Queen Cleopatra, likely had seizures as a child, but the evidence is only suggestive. His great-great-great grandnephews Caligula and Britannicus also had seizures. The etiology of these seizures in this Julio-Claudian family was most likely through inheritance, with the possibility of sudden unexpected death in epilepsy (SUDEP) in his great grandfather and also his father. Our best evidence comes from the ancient sources of Suetonius, Plutarch, Pliny, and Appianus.

Measurement of Persistent Organic Pollutants (POPs) in plastic resin pellets from remote islands : Toward establishment of baseline level for International Pellet Watch

Plastic resin pellets collected from remote islands in open oceans (Canary, St. Helena, Cocos, Hawaii, Maui Islands and Barbados) were sorted and yellowing polyethylene (PE) pellets were measured for polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane and the degradation products (DDTs), and hexachlorocyclohexanes (HCHs) by gas chromatograph equipped with mass spectrometer (GC-MS) and with electron capture detector (GC-ECD). PCBs were detected from all the pellet samples, confirming the global dispersion of PCBs. Median concentrations of PCBs (sum of 13 congeners : CB-66, CB-101, CB-110, CB-118, CB-105, CB-149, CB-153, CB-138, CB-128, CB-187, CB-180, CB-170, CB-206) in the remote island pellets ranged from 0.1 to 10 ng/g-pellet. These were one to three orders of magnitude lower than those observed for pellets from industrialized coastal zones (hundreds ng/g in Los Angeles, Boston, Tokyo; Ogata et al., 2009). Because these remote islands are far (>100 km) from industrialized zones, these concentrations (i.e., 0.1 to 10 ng/g-pellet) can be regarded as global "baseline" level of PCB pollution. Concentrations of DDTs in the remote island pellets ranged from 0.2 to 5.5 ng/g-pellet. At some locations, DDT was dominant over the degradation products (DDE and DDD), suggesting current usage of the pesticides in the islands. HCHs concentrations were 0.4 - 1.8 ng/g-pellet and lower than PCBs and DDTs, except for St. Helena Island at 18.8 ng/g-pellet where the current usage of the pesticides are of concern. The analyses of pellets from the remote islands provided "baseline" level of POPs (PCBs effects of global distillation, pellet samples from remote islands in higher latitude regions are necessary. From the eco-toxicological point of view, the fact that sporadic high concentrations of POPs were detected in some pellet samples from the remote islands is underscored. Some plastic debris which were contaminated in industrialized coastal zones may have rapidly

The Frontier Scientists National Science Foundation project titled Science in Alaska: Using Multimedia to Support Science Education produced research products in several formats: videos short and long, blogs, social media, a computer game, and a pop-up book. These formats reached distinctly different audiences. Internet users, public TV viewers, gamers, schools, and parents & young children were drawn to Frontier Scientists' research in direct and indirect ways. The analytics (our big data) derived from this media broadcast has given us insight into what works, what doesn't, next steps. We have evidence for what is needed to present science as an interesting, vital, and a necessary component for the general public's daily information diet and as an important tool for scientists to publicize research and to thrive in their careers. Collaborations with scientists at several Universities, USGS, Native organizations, tourism organizations, and Alaska Museums promoted accuracy of videos and increased viewing. For example, Erin Marbarger, at Anchorage Museum, edited, and provided Spark!Lab to test parents & child's interest in the pop-up book titled: The Adventures of Apun the Arctic Fox. Without a marketing budget Frontier Scientist's minimum publicity, during the three year project, still drew an audience. Frontier Scientists was awarded Best Website 2016 by the Alaska Press Club, and won a number of awards for short videos and TV programs.

Tacrolimus Updated Guidelines through popPK Modeling: How to Benefit More from CYP3A Pre-emptive Genotyping Prior to Kidney Transplantation

Directory of Open Access Journals (Sweden)

Jean-Baptiste Woillard

2017-06-01

Full Text Available Tacrolimus (Tac is a profoundly effective immunosuppressant that reduces the risk of rejection after solid organ transplantation. However, its use is hampered by its narrow therapeutic window along with its highly variable pharmacological (pharmacokinetic [PK] and pharmacodynamic [PD] profile. Part of this variability is explained by genetic polymorphisms affecting the metabolic pathway. The integration of CYP3A4 and CY3A5 genotype in tacrolimus population-based PK (PopPK modeling approaches has been proven to accurately predict the dose requirement to reach the therapeutic window. The objective of the present study was to develop an accurate PopPK model in a cohort of 59 kidney transplant patients to deliver this information to clinicians in a clear and actionable manner. We conducted a non-parametric non-linear effects PopPK modeling analysis in Pmetrics®. Patients were genotyped for the CYP3A4∗22 and CYP3A5∗3 alleles and were classified into 3 different categories [poor-metabolizers (PM, Intermediate-metabolizers (IM or extensive-metabolizers (EM]. A one-compartment model with double gamma absorption route described very accurately the tacrolimus PK. In covariate analysis, only CYP3A genotype was retained in the final model (Δ-2LL = -73. Our model estimated that tacrolimus concentrations were 33% IC95%[20–26%], 41% IC95%[36–45%] lower in CYP3A IM and EM when compared to PM, respectively. Virtually, we proved that defining different starting doses for PM, IM and EM would be beneficial by ensuring better probability of target concentrations attainment allowing us to define new dosage recommendations according to patient CYP3A genetic profile.

As a signatory of the Stockholm Convention and the largest developing country, China plays a very important role in implementation of the convention to reduce and finally eliminate persistent organic pollutants (POPs) in the world. In the past ten years after the enforcement in 2004, Chinese Government and scientists have made great progress on the study of POPs. The present work aims to provide an overview on recent studies on POPs in China, with particular focus on usage/emission inventory, residue inventory, and pollution status of POPs on national scale. Several legend (old) and new target POPs were comprehensively summarized with progress on inventory. Furthermore, several national scale monitoring programs have been selected for the occurrence, spatial and temporal trends of POPs in China, which are compared with Asian data and Global data. Based on the observed results, some important scientific issues, such as the primary and secondary distribution patterns, the primary and secondary fractionations, and air-soil exchange of POPs, are also discussed. It is proposed that more studies should be carried out for the new targeted POPs in future for both the national and global interests. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Conversazione con Angelo Liberati è un intervista rilasciata a chi scrive presso lo studio dell'artista, nel quartiere di Castello a Cagliari. In questo luogo evocativo, che tanto ha in comune con le sue opere per la ricchezza che lo contraddistingue, Liberati si è consegnato ad una chiacchierata a cuore aperto, quasi un flusso di coscienza, la 'confessione' di un 'realista' emerso dalla generazione pop. Una lettura consapevole e sincera della sua vita e delle sue opere, che si è rivelata una testimonianza viva, vibrante e partecipe degli anni della sua infanzia e della sua giovinezza, della scoperta dell’arte e dell’incontro con i suoi maestri, delle sue riflessioni e dei suoi ricordi sul mondo artistico a lui contemporaneo, della sua fascinazione per il mondo del cinema, ma anche di una lucida analisi della sua carriera artistica e di quelle difficoltà materiali e pratiche della vita del pittore nel mondo contemporaneo. Come per le sue opere in cui allestisce tutte le sue memorie, dalle ruminazioni colte ai ricordi personali e quotidiani, anche in questa 'confessione' occorre provare a ristabilire i nessi, ricongiungere passi lontani, che tuttavia si integrano, e catturare, pur nel frammento, qualcosa di profondo e di imprescindibile per leggere e comprendere la ricca produzione dell'artista.

Contextual cueing of pop-out visual search: when context guides the deployment of attention.

Science.gov (United States)

Geyer, Thomas; Zehetleitner, Michael; Müller, Hermann J

2010-05-01

Visual context information can guide attention in demanding (i.e., inefficient) search tasks. When participants are repeatedly presented with identically arranged ('repeated') displays, reaction times are faster relative to newly composed ('non-repeated') displays. The present article examines whether this 'contextual cueing' effect operates also in simple (i.e., efficient) search tasks and if so, whether there it influences target, rather than response, selection. The results were that singleton-feature targets were detected faster when the search items were presented in repeated, rather than non-repeated, arrangements. Importantly, repeated, relative to novel, displays also led to an increase in signal detection accuracy. Thus, contextual cueing can expedite the selection of pop-out targets, most likely by enhancing feature contrast signals at the overall-salience computation stage.

Footprinting analysis of interactions between the largest eukaryotic RNase P/MRP protein Pop1 and RNase P/MRP RNA components.

Science.gov (United States)

Fagerlund, Robert D; Perederina, Anna; Berezin, Igor; Krasilnikov, Andrey S

2015-09-01

Ribonuclease (RNase) P and RNase MRP are closely related catalytic ribonucleoproteins involved in the metabolism of a wide range of RNA molecules, including tRNA, rRNA, and some mRNAs. The catalytic RNA component of eukaryotic RNase P retains the core elements of the bacterial RNase P ribozyme; however, the peripheral RNA elements responsible for the stabilization of the global architecture are largely absent in the eukaryotic enzyme. At the same time, the protein makeup of eukaryotic RNase P is considerably more complex than that of the bacterial RNase P. RNase MRP, an essential and ubiquitous eukaryotic enzyme, has a structural organization resembling that of eukaryotic RNase P, and the two enzymes share most of their protein components. Here, we present the results of the analysis of interactions between the largest protein component of yeast RNases P/MRP, Pop1, and the RNA moieties of the enzymes, discuss structural implications of the results, and suggest that Pop1 plays the role of a scaffold for the stabilization of the global architecture of eukaryotic RNase P RNA, substituting for the network of RNA-RNA tertiary interactions that maintain the global RNA structure in bacterial RNase P. © 2015 Fagerlund et al.; Published by Cold Spring Harbor Laboratory Press for the RNA Society.

This is the second report of musicogenic epilepsy in Japan. A 23-year-old woman was admitted to our hospital due to the musicogenic epilepsy. She had four generalized tonic clonic seizures at 18 and 19 years old. Since 19, she had had complex partial seizures lasting for about 20 seconds which was easily evoked by listening to an American pops particularly "Dreamlover" song by Mariah Carey. Brian MRI and interictal 99mTc HMPAO-SPECT showed no abnormalities. In the ictal EEG recording, three minutes after listening to the song, seizure activities were recorded from the right temporal region with 11Hz rhythmic epileptiform activities over the right temporal region and subsequent delta activities over the right hemisphere. The song that induced the seizure had a specific meaning that might evoke her emotion as had been pointed out in the previous reports.

POPs and other persistent organic compounds in fish from remote alpine lakes in the Grisons, Switzerland

Schmid, P.; Gujer, E.; Zennegg, M. [Swiss Federal Laboratories for Materials Testing and Research (EMPA), Duebendorf (Switzerland); Lanfranchi, M. [Agency for Nature and Environment of the Canton Grisons, Chur (Switzerland)

Global transfer of persistent semivolatile organic compounds, such as persistent organic pollutants (POPs), is effected by long-range atmospheric transport in combination with condensation and volatilization processes. Within the global atmosphere, evaporation in warm latitudes and deposition in cold latitudes leads to a transfer of contaminants towards the poles. The phenomenon of atmospheric migration of semivolatile chemicals, such as PCB and DDT, has been predicted and associated with the term ''global distillation'' by Goldberg, and the model has been extensively reviewed by Mackay and Wania. For comparatively less volatile components such as PCDD/F and PBDE, particle-bound deposition is the dominating transfer mechanism. Therefore, the input of these compounds in remote alpine regions without point sources is controlled by atmospheric deposition (dry and wet) and condensation. For organochlorine compounds, such as pesticides and polychlorinated biphenyls (PCB), it has been shown that accumulation is enhanced by temperaturecontrolled condensation also in alpine regions with low average temperatures. The hydrology of remote alpine lakes is determined by direct atmospheric deposition feeding and feeding with water from the surrounding catchment area, without significant inputs from tributaries or from nearby anthropogenic activities. Fish dwelling in these ecosystems represents an excellent indicator for the long-term input of bioaccumulating contaminants, such as POPs and other persistent organic compounds. In the present study, fish from 7 alpine lakes from the Grisons (Switzerland) situated between 2062 and 2637 m above sea level were investigated. With the exception of Laghetto Moesola which is situated adjacent to a mountain pass road, input from local anthropogenic emissions can be excluded for these lakes.

Persistent organic pollutants (i.e. PCBs, DDTs, and HCHs) were analyzed along Australia and New Zealand North Island coastlines. PCB concentrations were high in urban areas (107-294 ng/g-pellet), with Sydney Harbour the most polluted. Hepta-chlorinated PCB was abundant, with ~30% in urban areas suggesting legacy pollution. DDT concentrations showed similar pattern except in rural agricultural sites, Taupo Bay and Ahipara, New Zealand (23 and 47 ng/g-pellet). p,p'-DDE predominance at these 2 sites suggested historical input; they also had high HCH concentrations (17 and 29 ng/g-pellet). The role of International Pellet Watch (IPW) in science communication was studied through feedbacks from IPW volunteers, case studies and examples. IPW data were categorized into understandable terms and tailored reports based on volunteers' backgrounds complemented with pollution maps. The effectiveness of IPW science communication has led to its use in awareness and education activities focusing on both POPs and plastic debris issues. Copyright © 2015 Elsevier Ltd.

Full Text Available The aim of this article is, firstly, to determine the Young people’s preference reasons of popular novels. What meanings the popular novels preferred by the young have added to their lives and the underlying reasons why this genre is read more than the aesthetic novels, have been put forth. In the introduction part, the general characteristics of the popular novel have been presented. In this part, the widespread perception that popular novel is not a genre which is so noteworthy has been stated. Popular novels are the type of novels which are written without any aesthetic purpose in terms of their writers; in the writing and the publication process of which there are some reasons out of art; primarily, commercial concern; which aim to stimulate the reader’s excitement rather than ideas; which reach a great number of readers; which are understood and resolved easily; which don’t search for a specific level in their readers and present a stereotyped structure; most of which have been filmed and reached many viewers in cinemas and on the television apart from the readers. On the other hand, aesthetic novels are the novels which are written for aesthetic purposes by their writers; which are considered as a serious effort; the publication of which are not only based on commercial reasons; which take the readers from ready emotion and idea patterns and bring them to a position where they question everything; again, which search for an aesthetic background in the readers to some extent; thus; reaching less number of readers; which have an originality in terms of setting and narration technique. In this study, it has been found that the young do not perceive the popular novels as in the definition above. As it has been pointed out in the introduction part, even if popular novel is subjected to negative evaluations compared to aesthetic novel this situation does not change the fact that it is a most read genre. Starting from this fact, in this

Full Text Available As Spice Girls são um dos mais bem-sucedidos grupos musicais da década de 1990, tendo se tornado especialmente famosas por sua exaltação do 'poder jovem feminino'. Relacionado a um estudo que se baseia em entrevistas com fãs e ex-fãs desse grupo feminino, o presente artigo discute até que ponto fenômenos do 'feminismo pop' como as Spice Girls podem ser considerados uma fonte de empoderamento para meninas e jovens. O método documentário é utilizado por permitir a análise da recepção midiática como parte de uma cultura popular. Uma abordagem mimética em relação às Spice Girls no interior dessa cultura popular possibilita que suas fãs ocupem identificações diferenciadas na busca de seu próprio posicionamento diante das exigências contraditórias que a sociedade faz às adolescentes. Demonstra-se que suas complicadas negociações se referem a um empoderamento que não pode ser adequadamente categorizado como resistência ou incorporação ideológica.The Spice Girls as one of the most successful bands of the nineteen-nineties have become particularly famous for their proclamation of 'girl power'. With reference to an interview-based study with fans and ex-fans of the girl group the article discusses to what extent 'pop feminist' phenomena like the Spice Girls can be considered a source of empowerment for young women and girls. The 'documentary method' is introduced as a method which allows the analysis of media reception as part of a popular culture. A mimetic approach towards the Spice Girls within this popular culture allows their fans to experiment in finding their own position between the contradictory demands society makes on them as adolescents. It will be shown that their complicated negotiations refer to an empowerment which cannot be adequately grasped within categories of resistance and incorporation of ideology.

Guzzella, Licia; Salerno, Franco; Freppaz, Michele; Roscioli, Claudio; Pisanello, Francesca; Poma, Giulia

2016-02-15

Due to their physico-chemical properties, POPs and PAHs are subjected to long-range atmospheric transport (LRAT) and may be deposited in remote areas. In this study, the contamination with DDx, PCBs, PBDEs, and PAHs was investigated in sediments and soils collected on the southern slopes of Mt. Everest (Himalaya, Nepal) in two different sampling campaigns (2008 and 2012). The results showed a limited contamination with POPs and PAHs in both soil and sediment samples. Therefore, the southern slopes of Mt. Everest can be considered a remote area in almost pristine condition. The LRAT mechanism confirmed its primary role in the transfer of contaminants to remote regions, while the gradual melting of glaciers, due to global warming, and the subsequent release of contaminants was suggested to be a secondary source of pollution of the lake sediments. In addition, the increase of tourism in this area during the last decades might have influenced the present concentrations of PAHs in the sediments and soils. Copyright © 2015 Elsevier B.V.

Great Apes

Sleeman, Jonathan M.; Cerveny, Shannon

2014-01-01

Anesthesia of great apes is often necessary to conduct diagnostic analysis, provide therapeutics, facilitate surgical procedures, and enable transport and translocation for conservation purposes. Due to the stress of remote delivery injection of anesthetic agents, recent studies have focused on oral delivery and/or transmucosal absorption of preanesthetic and anesthetic agents. Maintenance of the airway and provision of oxygen is an important aspect of anesthesia in great ape species. The provision of analgesia is an important aspect of the anesthesia protocol for any procedure involving painful stimuli. Opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) are often administered alone, or in combination to provide multi-modal analgesia. There is increasing conservation management of in situ great ape populations, which has resulted in the development of field anesthesia techniques for free-living great apes for the purposes of translocation, reintroduction into the wild, and clinical interventions.

The rapid deterioration of the world's major ecosystems has intensified the need for effective monitoring and development of operational indicators of ecosystem health, and the extension of health to describe regional ecosystems is a response to accumulating evidence that humandominated ecosystems have become highly dysfunctional. The Lagoon of Venice is probably one of the world's best-known examples of an ecosystem that has been historically influenced by human intervention since the XVth century. The area has a long history of industrial activity (even recent, mainly after World War II), with oil refining and several chemical production plants around the Lagoon. Only recently has Venice also been recognised because of its environmental problems, mainly due to POPs accumulating in sediments and seafood which has aroused local concern. It is well-known that one important effect of ecosystem degradation is an increased risk to the health of human populations. In the case of POPs, the simplest way for humans to be exposed is through the consumption of food contaminated by dioxins and PCBs. Due to bio-accumulation and long-term exposure (additives) to these pollutants, even minimal doses of dioxins and PCBs can result in negative effects on health. Human health should thus be understood within an ecological framework as an expression of the life-supporting capacity of the environment. Consequently, human health becomes an important criterion of sustainability - one which, over time, signals whether we are satisfactorily sustaining the social and ecological realms. This paper gathers together recent data on dioxins and PCBs, related both to the environment and to human health, in order to emphasize the need for intervention.

Full Text Available The Heroism of women in the African Epic: A critical analysis of Sundiata or the mandingo Epic, Emperor Shaka The Great: A Zulu Epic and Nsongo’a Lianja: The national Epic of the Nkundo. In African epics, female figures perform salient heroic roles that are, unfortunately, not widely recognised and celebrated, as notions of bravery and heroism are understood from a male perspective. Against this backdrop, this study adopts new critical and conceptual approaches to interrogate existing narratives, discourse and ideas on/or about female heroism. By focusing on selected epics, this work incorporates perceptions about women in folktales whose themes comment and reflect on the presentation of female characters and the roles they execute in society. The present contribution critically examines the role of supernatural forces in female characters’ commitment and heroism; not only protecting Soundiata, Shaka, and Lianja in accomplishing their destinies but also showcasing the activities, traditions, belief systems and culture of the Mandingo, Zulu, and Mongo in their respective societies.

Full Text Available Most of the electricity used in Brazil comes from hydroelectric plants, mainly due to the great availability of its water resources. However, the construction of these plants denotes serious problems related to migration of native fish and the genetic conservation of stocks. Current study evaluates two wild population of Leporinus elongatus (piapara located downstream (Population A - PopA and upstream (Population B - PopB of the Cachoeira Branca before the construction of the São Domingos hydroelectric plant (HPP in the Mato Grosso do Sul State, Brazil. Thirty samples from caudal fins were collected and analyzed for each population. Eighty-nine fragments, including 72 polymorphic ones (80.9%, were analyzed. Low fragments (less than 0.100 in both populations (PopA = 2 and PopB = 3 were identified. Nine fixed fragments (frequency 1.000 (PopA = 3 and PopB = 6, and four exclusive fragments (PopA = 3 and PopB = 1 were also reported. The genetic variability within populations, calculated by Shannon Index and by percentage of polymorphic fragments, indicated high rates of intrapopulation variability (PopA = 0.309 and 61.80% and PopB = 0.392 and 71.90%, respectively. Genetic distance and identity rates (0.089 and 0.915, respectively were different between populations, whilst AMOVA showed that most variations lie within the populations and not between them. Fst and Nm rates showed moderate genetic differentiation with low numbers of migrants. Results reveal populations with high intra-population genetic variability and genetic differentiation, with low gene flow. The passage ladders of São Domingos HPP should control fish transposition to preserve genetic variability.

Discriminability and dimensionality effects in visual search for featural conjunctions: a functional pop-out.

Science.gov (United States)

Dehaene, S

1989-07-01

Treisman and Gelade's (1980) feature-integration theory of attention states that a scene must be serially scanned before the objects in it can be accurately perceived. Is serial scanning compatible with the speed observed in the perception of real-world scenes? Most real scenes consist of many more dimensions (color, size, shape, depth, etc.) than those generally found in search paradigms. Furthermore, real objects differ from each other along many of these dimensions. The present experiment assessed the influence of the total number of dimensions and target/distractor discriminability (the number of dimensions that suffice to separate a target from distractors) on search times for a conjunction of features. Search was always found to be serial. However, for the most discriminable targets, search rate was so fast that search times were in the same range as pop-out detection times. Apparently, greater discriminability enables subjects to direct attention at a faster rate and at only a fraction of the items in a scene.

Biomagnification of hexachlorobenzene: influence of uptake routes in a laboratory test; Aufnahmepfade von POPs in Biota. Biomagnifikation von Hexachlorobenzol im Labortest

In order to evaluate such a potential biomagnification, a laboratory test was developed. It consisted of a two-step food chain including the sediment dwelling freshwater oligochaete Tubifex tubifex (Mueller) and the three-spined stickleback (Gasterosteus aculeatus, Linne), a small teleost fish which often feeds primarily on benthic invertebrates. Artificial sediment and reconstituted water were used. To examine the influence of benthic prey on the bioaccumulation of a POP in the predator, fish were exposed to {sup 14}C-labelled hexachlorobenzene via spiked water, spiked sediment, pre-contaminated prey organisms, and to combinations of these exposure routes. Summarising the results of these experiments, it could be shown that the exposure to HCB via different routes resulted in a significantly higher accumulation in fish than an exposure to single pathways. It was concluded that the major uptake routes for fish were the overlying water and the food, whereas the contribution of spiked sediment itself was relatively small. HCB was biomagnified in the tested laboratory food chain. Therefore, concerning secondary poisoning, the environmental risk assessment of POPs like HCB should not be based on existing bioaccumulation tests alone, since they focus only on exposure via the water pathway. Instead, the influence of food and sediment as exposure routes should be considered as well, using comprehensive food chain modelling and/or laboratory studies. (orig.)

Identification of four families of yCCR4- and Mg2+-dependent endonuclease-related proteins in higher eukaryotes, and characterization of orthologs of yCCR4 with a conserved leucine-rich repeat essential for hCAF1/hPOP2 binding

Directory of Open Access Journals (Sweden)

2001-11-01

Full Text Available Abstract Background The yeast yCCR4 factor belongs to the CCR4-NOT transcriptional regulatory complex, in which it interacts, through its leucine-rich repeat (LRR motif with yPOP2. Recently, yCCR4 was shown to be a component of the major cytoplasmic mRNA deadenylase complex, and to contain a fold related to the Mg2+-dependent endonuclease core. Results Here, we report the identification of nineteen yCCR4-related proteins in eukaryotes (including yeast, plants and animals, which all contain the yCCR4 endonuclease-like fold, with highly conserved CCR4-specific residues. Phylogenetic and genomic analyses show that they form four distinct families, one of which contains the yCCR4 orthologs. The orthologs in animals possess a leucine-rich repeat domain. We show, using two-hybrid and far-Western assays, that the human member binds to the human yPOP2 homologs, i.e. hCAF1 and hPOP2, in a LRR-dependent manner. Conclusions We have identified the mammalian orthologs of yCCR4 and have shown that the human member binds to the human yPOP2 homologs, thus strongly suggesting conservation of the CCR4-NOT complex from yeast to human. All members of the four identified yCCR4-related protein families show stricking conservation of the endonuclease-like catalytic motifs of the yCCR4 C-terminal domain and therefore constitute a new family of potential deadenylases in mammals.

Pop up satellite tags impair swimming performance and energetics of the European eel (Anguilla anguilla)

Pop-up satellite archival tags (PSATs) have recently been applied in attempts to follow the oceanic spawning migration of the European eel. PSATs are quite large, and in all likelihood their hydraulic drag constitutes an additional cost during swimming, which remains to be quantified, as does...... the potential implication for successful migration. Silver eels (L(T)=598.6 +/- 29 mm SD, N = 9) were subjected to swimming trials in a Steffensen-type swim tunnel at increasing speeds of 0.3-0.9 body lengths s(-1), first without and subsequently with, a scaled down PSAT dummy attached. The tag significantly...... increased oxygen consumption (MO(2)) during swimming and elevated minimum cost of transport (COT(min)) by 26 Standard (SMR) and active metabolic rate (AMR) as well as metabolic scope remained unaffected, suggesting that the observed effects were caused by increased drag.

Great Lakes Literacy Principles

Fortner, Rosanne W.; Manzo, Lyndsey

2011-03-01

Lakes Superior, Huron, Michigan, Ontario, and Erie together form North America's Great Lakes, a region that contains 20% of the world's fresh surface water and is home to roughly one quarter of the U.S. population (Figure 1). Supporting a $4 billion sport fishing industry, plus $16 billion annually in boating, 1.5 million U.S. jobs, and $62 billion in annual wages directly, the Great Lakes form the backbone of a regional economy that is vital to the United States as a whole (see http://www.miseagrant.umich.edu/downloads/economy/11-708-Great-Lakes-Jobs.pdf). Yet the grandeur and importance of this freshwater resource are little understood, not only by people in the rest of the country but also by many in the region itself. To help address this lack of knowledge, the Centers for Ocean Sciences Education Excellence (COSEE) Great Lakes, supported by the U.S. National Science Foundation and the National Oceanic and Atmospheric Administration, developed literacy principles for the Great Lakes to serve as a guide for education of students and the public. These “Great Lakes Literacy Principles” represent an understanding of the Great Lakes' influences on society and society's influences on the Great Lakes.

Autonomy, Submission or Sound Hybridization? The Construction of the Aesthetic Canon of the Spanish Pop-Rock

JAVIER NOYA

2014-01-01

Full Text Available This paper provides an approach to the aesthetic canon of Spanish pop-rock, which is understood as being the musicians, bands and works which have had the most infl uence on this musical genre in Spain. Using Bourdieu?s sociology of art and its application to popular music studies, surveys have been analysed that were carried out by both Spanish music critics and musicians. The hypothesis posed is whether an autochthonous aesthetic canon exists, and whether this is determined by an Anglo- American influence. From lists or rankings published whether in books or in general or specialist magazines, these data were combined to obtain a meta-ranking, which was tested by using certain statistical tests. From this, some characteristics particular to the Spanish aesthetic canon have been obtained, as well as some which are shared with the Englishspeaking canon.

DynaPop-X: A population dynamics model applied to spatio-temporal exposure assessment - Implementation aspects from the CRISMA project

Science.gov (United States)

Aubrecht, Christoph; Steinnocher, Klaus; Humer, Heinrich; Huber, Hermann

2014-05-01

In the context of proactive disaster risk as well as immediate situational crisis management knowledge of locational social aspects in terms of spatio-temporal population distribution dynamics is considered among the most important factors for disaster impact minimization (Aubrecht et al., 2013a). This applies to both the pre-event stage for designing appropriate preparedness measures and to acute crisis situations when an event chain actually unfolds for efficient situation-aware response. The presented DynaPop population dynamics model is developed at the interface of those interlinked crisis stages and aims at providing basic input for social impact evaluation and decision support in crisis management. The model provides the starting point for assessing population exposure dynamics - thus here labeled as DynaPop-X - which can either be applied in a sense of illustrating the changing locations and numbers of affected people at different stages during an event or as ex-ante estimations of probable and maximum expected clusters of affected population (Aubrecht et al., 2013b; Freire & Aubrecht, 2012). DynaPop is implemented via a gridded spatial disaggregation approach and integrates previous efforts on spatio-temporal modeling that account for various aspects of population dynamics such as human mobility and activity patterns that are particularly relevant in picturing the highly dynamic daytime situation (Ahola et al., 2007; Bhaduri, 2008; Cockings et al., 2010). We will present ongoing developments particularly focusing on the implementation logic of the model using the emikat software tool, a data management system initially designed for inventorying and analysis of spatially resolved regional air pollutant emission scenarios. This study was performed in the framework of the EU CRISMA project. CRISMA is funded from the European Community's Seventh Framework Programme FP7/2007-2013 under grant agreement no. 284552.

Grace Wang

2012-06-01

Full Text Available How did singer Wang Leehom, a Chinese American raised in the suburbs of New York, end up becoming one of the industry heavyweights of Mandopop (Mandarin-language pop music? This essay uses Wang as a case study to investigate how discourses of race, market, and belonging are reworked in global contexts. Drawing on Sau-ling Wong’s theoretical insights on transnational processes of race, citizenship, and belonging, it argues that Wang capitalizes on a fluid dynamic of sameness and difference to appeal to a heterogeneous Chinese-speaking audience that stretches across China to Taiwan, Hong Kong, Southeast Asia, and the greater Chinese diaspora. Through an examination of the racial and national contexts that frame Wang’s participation in Mandopop, this essay analyzes the particular calibrations of Chineseness that emerge from the singer’s music and public image and the imperfect translation of identities such as Chinese American, Chinese diasporic, and Chinese across diverse linguistic and national communities.

„Lenin’s Ghost!” History of Soviet Comics Characters in American Pop Culture

Przemysław Dudziński

2014-01-01

Full Text Available The tension between Soviet Union and United States thatdefined the global political landscape of the second half of the twentiethcentury, had its clear impact on perceptions and creation of Soviet heroes in the context of American culture. The first and primary goal of our article is to investigate and describe the functioning of a particular theme – Russian characters, especially Russian meta-humans in the area of American popular culture, especially mainstream comics. This inquiry is intended to demonstrate the basic historical dimension, i.e. the periods of growth and decline in popularity, and even the complete disappearance of that theme. The purpose of the second goal is an attempt to analyze the structures of comics characters associated with the Soviet Union and place them in a broader historical and cultural context. These treatments allow to signal changes in time-sensitive structure, which consists of values, stereotypes and pop culture clichés appropriate for the American culture. Thus, we hope that this article will be an important contribution to the further study of these issues.

Faint Lyα emitters become increasingly rarer toward the reionization epoch (z ∼ 6–7). However, observations from a very large (∼5 deg{sup 2}) Lyα narrow-band survey at z = 6.6 show that this is not the case for the most luminous emitters, capable of ionizing their own local bubbles. Here we present follow-up observations of the two most luminous Lyα candidates in the COSMOS field: “MASOSA” and “CR7.” We used X-SHOOTER, SINFONI, and FORS2 on the Very Large Telescope, and DEIMOS on Keck, to confirm both candidates beyond any doubt. We find redshifts of z = 6.541 and z = 6.604 for “MASOSA” and “CR7,” respectively. MASOSA has a strong detection in Lyα with a line width of 386 ± 30 km s{sup −1} (FWHM) and with very high EW{sub 0} (>200 Å), but undetected in the continuum, implying very low stellar mass and a likely young, metal-poor stellar population. “CR7,” with an observed Lyα luminosity of 10{sup 43.92±0.05} erg s{sup −1} is the most luminous Lyα emitter ever found at z > 6 and is spatially extended (∼16 kpc). “CR7” reveals a narrow Lyα line with 266 ± 15 km s{sup −1} FWHM, being detected in the near-infrared (NIR) (rest-frame UV; β = −2.3 ± 0.1) and in IRAC/Spitzer. We detect a narrow He ii 1640 Å emission line (6σ, FWHM = 130 ± 30 km s{sup −1}) in CR7 which can explain the clear excess seen in the J-band photometry (EW{sub 0} ∼ 80 Å). We find no other emission lines from the UV to the NIR in our X-SHOOTER spectra (He ii/O iii] 1663 Å > 3 and He ii/C iii] 1908 Å > 2.5). We conclude that CR7 is best explained by a combination of a PopIII-like population, which dominates the rest-frame UV and the nebular emission, and a more normal stellar population, which presumably dominates the mass. Hubble Space Telescope/WFC3 observations show that the light is indeed spatially separated between a very blue component, coincident with Lyα and He ii emission, and two red components (∼5 kpc away), which

The effects of establishing a gray wolf (Canis lupus) population in Yellowstone National Park were predicted for three ungulate species—elk (Cervus elaphus), mule deer (Odocoileus hemionus), and moose (Alces alces)—using previously developed POP-II population models. We developed models for 78 and 100 wolves. For each wolf population, we ran scenarios using wolf predation rates of 9, 12, and 15 ungulates/wolf/year. With 78 wolves and the antlerless elk harvest reduced 27%, our modeled elk population estimated were 5-18% smaller than the model estimate without wolves. With 100 wolves and the antlerless elk harvest reduced 27%, our elk population estimated were 11-30% smaller than the population estimates without wolves. Wolf predation effects were greater on the modeled mule deer population than on elk. With 78 wolves and no antlerless deer harvest, we predicted the mule deer population could be 13-44% larger than without wolves. With 100 wolves and no antlerless deer harvest, the mule deer population was 0-36% larger than without wolves. After wolf recovery, our POP-II models suggested moose harvests would have to be reduced at least 50% to maintain moose numbers at the levels predicted when wolves were not present. Mule deer and moose population data are limited, and these wolf predation effects may be overestimated if population sizes or male-female ratios were underestimated in our population models. We recommend additional mule deer and moose population data be obtained.

Purely organic biluminescent materials are of great interest due to the involvement of both singlet and long-lived triplet emissions, which have been used in bio-imaging and organic light-emitting diodes. We show two molecules 3,4,5,6-tetraphenyloxy-phthlonitrile (POP) and 3,4,5,6-tetrakis-p-tolyloxy-phthalonitrile (TOP), in which POP was found to exhibit fluorescence and persistent room-temperature green phosphorescence (pRTGP) in the amorphous and crystal states. Both POP and TOP show aggregation induced emission in tetrahydrofuran-water mixture. We found in single crystal X-ray analysis that intra-and inter molecular lp(O)•••π interactions along with (π(C=C)•••π(C≡N), hydrogen bond (H-B), and C-H•••π interactions induce head-to-tail slipped-stacked arrangement in POP. In addition, X-ray structure of TOP with slipped-stack arrangement induced by only (π(C=C)•••π(C≡N) and H-B interactions, shows dim afterglow only in crystals. These indicate that more number of non-covalent interactions may reinforce relatively efficient inter system crossing that leads to pRTGP even in the amorphous state of POP. Given the unique green afterglow feature in amorphous state of POP, document security protection application is achievable.

A ‘Social Form Of Knowledge’ in Practice: Unofficial Compiling of 1960s Pop Music on CD-R

Paul Martin

2012-01-01

Full Text Available In this article I explore the ‘unofficial’ (and technically illegal compiling of marginally known 1960s pop records on Compact Disc Recordable (CD-R. I do so by situating it within the proposition by the late Raphael Samuel, that history is ‘social knowledge’ and a practice rather than a profession. I propose that this compiling activity exemplifies this proposition. The core of the paper is centred on a 2007 survey which I conducted via three on-line 1960s music enthusiast discussion forums. I draw on the sixteen responses to demonstrate how the motivations, values and intentions of those respondents engaging in the practice of CD-R compiling are historically and socially centred. In doing so, I seek to problematise the music industry’s undifferentiated condemnation of all copying as theft. I do so by showing how, far from stealing, these CD-R compilers are adding to the musical social knowledge of 1960s pop and rock music. I further situate them within a longer lineage of ‘unofficial listening’ dating back to at least the 1930s. In using the term ‘unofficial’ in both a legal and public historical sense (eg to take issue with a received narrative, I point to wider definitions of what historically has or has not been musically ‘official’ to listen to. I seek also to point to the practice of CD-R compiling as a historical ‘moment’ in technological change, which might otherwise go unremarked upon as the CD-R itself heads towards utilitarian obsolescence. Although, the issues and concepts raised in the paper can be little more than pointed to, it is hoped it might act as one platform for the historical engagement with a subject more commonly discussed in sociological terms. As public historians we should be reflexive and inter-disciplinary and it is with this mind set that this article is written.

Full Text Available This article explores the life of Nicolae Pop Balomiri, a Greek-Catholic Protopope and Orthodox Archimandrite. Appointed General Vicar by the exiled Bishop Inochentie Micu-Klein in 1747, Balomiri fled Transylvania shortly afterwards when the Court in Vienna refused to acknowledge his appointment, instead supporting his predecessor, Petru Pavel Aaron. Early on in his exile, Balomiri converted to Orthodoxy, and was later made Archimandrite of the Monastery of Curtea de Argeş. From exile in Wallachia, he continued to campaign for the rights of Romanian Orthodox Christians in Transylvania, lobbying Russian Empress Elisabeta Petrovna to intervene with the Viennese to request a non-United bishop for Transylvania. Many historians have glossed over Balomiri’s importance, possibly because of his controversial role as an apostate priest.

Scientists observe the world around them in an attempt to understand it. Artists observe the world around them in an attempt to create a reflection or response to the environment. It is critical for the two fields to work together in order to engage and inform the general population. The Consortium for Ocean Leadership, the International Ocean Discovery Program and a series of collaborators are designing a traveling exhibit that will inspire underserved communities in the excitement of exploration, the process of science, and the people and tools required to get there. The project aims to learn more about how to increase access to and awareness of ocean/earth science by bringing a pop-up style museum exhibit to local libraries and public events. As an artist with a science and education background and the graphic designer for this exhibit, this author will highlight the ways this project utilizes art and design to educate underserved populations in ocean and geosciences.

Polyurethane foam (PUF) disk passive air samplers were deployed concurrently at five sites across Kolkata megacity and the rural mangrove wetland of Sundarban (UNESCO World Heritage Site) between January-March in 2014. Samples were analyzed for hexachlorocyclohexanes (HCHs), dichlorodiphenyltricholoroethanes (DDTs), polychlorinated biphenyls (PCBs) and, polybrominated diphenyl ethers (PBDEs) using gas chromatography and mass spectrometry (GC-MS). Derived air concentrations (pg/m 3 ) for Kolkata ranged: for ∑α- and γ-HCH between 70 and 207 (114 ± 62), ∑ 6 DDTs: 127-216 (161 ± 36), ∑ 7 PCBs: 53-213 (141 ± 64), and ∑ 10 PBDEs: 0.30-23 (11 ± 9). Low values for all the studied POPs were recorded in the remote area of the Sundarban site (with the exception of DDTs: o,p'-DDT and p,p'-DDT), where ∑ 4 DDTs was 161 ± 36. In particular, the site of Ballygunge, located in the southern part of Kolkata, showed the highest level of all the metabolites/congeners of POPs, suggesting a potential hot spot of usage and emissions. From HCHs, α-/γ-HCH isomers ratio was low (0.67-1.96) indicating a possible sporadic source of lindane. γ-HCH dominated the HCH signal (at 3 sites) reflecting wide spread use of lindane both in Kolkata and the Sundarban region; however, isomeric composition in Kolkata also suggests potential technical HCHs use. Among DDT metabolites, both o,p'-DDT and p,p'-DDT shared the dominant percentages accounting for ∼26-46% of total DDTs followed by p,p'-DDE (∼12-19%). The PCB congener profile was dominated by tri- and tetra-Cl at the southern and eastern part of Kolkata. These results are one of the few contributions that reports air concentrations of POPs, concurrently, at urban and remote villages in India. These data are useful to assess atmospheric pollution levels and to motivate local and regional authorities to better understand the potential human exposure risk associated to urban areas in India.

To compare radiological and functional outcome of external fixation and distraction with conservative Plaster of Paris (POP) cast for unstable intra-articular fractures of the distal radius. The study was conducted on 60 patients with unstable intra-articular fracture of distal radius who reported to emergency or outpatient Orthopaedic Surgery department of Benazir Bhutto Hospital, Rawalpindi, between March and August 2007. They were divided into two equal groups: Group A and Group B, treated by Plaster of Paris cast, and external fixation with distraction respectively. The functional outcome in terms of freedom from pain, range of movement, grip power and deformity, and the radiological outcome of radial length, incongruity and radio-ulnar joint position were analysed at three months follow-up using a 3-point scoring scale. In Group A, 1 (3%) patient showed excellent result, 8 (27%) patients good results, 19 (63%) patients fair results and 2 (7%) patients poor result. In Group B, 14 (47%) patients showed excellent results, 11 (37%) patients good results, 4 (13%) patients fair results and 1 (3%) patient poor result. The outcome score of the Group B patients was significantly better compared to the Group A patients (p value advantages over conventional Plaster of Paris cast in the treatment of unstable intra-articular fractures of distal radius.

Persistent organic pollutants including organochlorine pesticides, PCBs, and PCDDs/DFs were determined in the blubber of Caspian seals, which died during an outbreak of canine distemper virus in 2000 and 2001. DDTs were the predominant contaminants that ranged from 3.1 to 560 μg/g lipid. A negative correlation was observed between concentration of contaminants and blubber thickness. During spring, as the blubber layer becomes thin after breeding and moulting, seals may face higher risk due to the increased concentration of organochlorines in their bodies. TEQs in the blubber of Caspian seals (10-340 pg TEQ/g) were lower than those in seals from other locations, suggesting that toxic effects of these contaminants are a deal less in the present population and they are unlikely to be linked to mass mortality. The levels of PCBs and pesticides in Caspian seals, however, comparable to those in other aquatic mammals that have suffered from epizootics, might pose a risk of immunosuppression. - POPs in seals are high enough to induce immunosuppression

The Great Lakes region, as defined here, includes the Great Lakes and their drainage basins in Minnesota, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, and New York. The region also includes the portions of Minnesota, Wisconsin, and the 21 northernmost counties of Illinois that lie in the Mississippi River drainage basin, outside the floodplain of the river. The region spans about 9º of latitude and 20º of longitude and lies roughly halfway between the equator and the North Pole in a lowland corridor that extends from the Gulf of Mexico to the Arctic Ocean.The Great Lakes are the most prominent natural feature of the region (Fig. 1). They have a combined surface area of about 245,000 square kilometers and are among the largest, deepest lakes in the world. They are the largest single aggregation of fresh water on the planet (excluding the polar ice caps) and are the only glacial feature on Earth visible from the surface of the moon (The Nature Conservancy 1994a).The Great Lakes moderate the region’s climate, which presently ranges from subarctic in the north to humid continental warm in the south (Fig. 2), reflecting the movement of major weather masses from the north and south (U.S. Department of the Interior 1970; Eichenlaub 1979). The lakes act as heat sinks in summer and heat sources in winter and are major reservoirs that help humidify much of the region. They also create local precipitation belts in areas where air masses are pushed across the lakes by prevailing winds, pick up moisture from the lake surface, and then drop that moisture over land on the other side of the lake. The mean annual frost-free period—a general measure of the growing-season length for plants and some cold-blooded animals—varies from 60 days at higher elevations in the north to 160 days in lakeshore areas in the south. The climate influences the general distribution of wild plants and animals in the region and also influences the activities and distribution of the human

Population of goats related to climate in western India: an ecological assessment

Western India experiences arid to dry subhumid ecoclimate. Aridity increases from east to west to the Great Indian Desert or Thar Desert. The desert economy is animal based and goats are the most common livestock; density of goats increases with increase in aridity. There are large morphological variations in goats warranting the recognition of population differences throughout the region. The present investigations were therefore undertaken to see whether there are population differences and, if so, to establish the populations on a sound ecological basis. Eleven physical measurements of the animals were made in the fields of western India in a total of 518 animals (255 adults). Five populations were initially segregated by means of a scatter diagram. Population differences were confirmed by mathematical treatments using analysis of variance (one-way and two-way) and Students-Newman-Keuls test, which yields a critical comparison among means. Discriminant analysis was used to determine whether the goat populations differed significantly between the five climo-edaphic-vegetational zones. Each population was designated according to the locality having the greatest density as: POP1Ku, POP2Sa, POP3Jh, POP4Ga, POP5Pa. The five populations occurring in distinct climo-edaphic-vegetational zones or ecological niches in western India may be referred to as ecotypes.

Full Text Available Introduction : Pelvic organ prolapse (POP is treated with a great variety of procedures and none is fully satisfactory. The aim of the study was to introduce and evaluate the effectives of laparoscopic trans teres vault suspension (LTTVS technique as a new method for POP treatment. Material and methods: In the years 2013-2014, eight symptomatic women with grades II-IV POP underwent LTTVS procedure. The mean age of patients was 65.25 years (range from 52 to 76 years. The surgery encompassed total hysterectomy, suturing the vagina and fixation of uterosacral ligaments to the vaginal stump, fixation of stumps of round ligaments to the vaginal stump, and fixation of the vaginal stump to the anterior rectus fascia. Mean follow-up was 17.75 months (range from 6 to 27 months. Results : Eight patients were successfully operated. The symptoms of POP resolved after surgery and subjective quality of life increased. In one case a complication such as common fibular nerve injury appeared; however, it resolved after one month of physiotherapy. The other patient reported radiating pain down the leg after three months. No recurrence of vaginal stump prolapse was observed during the follow-up. Conclusions : LTTVS is a promising method for POP treatment. Due to repair with the use of native tissues, physiological placement of vaginal stump, and high efficacy it can be considered as an alternative to other POP surgeries. The method requires additional research on larger groups of patients.

The Possibility of Social Change and Pop Music in Serbia: Šobaja’s Three Kisses – A Case Study

Full Text Available Can social change be brought about only in a radical manner? Is a radical manner of bringing about change possible at all? When we say social change, do we mean "revolution"? Is there a different way of looking at social change, and what is the role of elite culture and that of popular culture in these processes? Has the temporally and contextually limited effect of change and guerilla subversion through popular culture proved more effective? This small-scale study aims to raise the question of whether pop music can contribute to positive changes in society, and examines the conditions for this possibility through the case study of Nebojša "Šobaja" Anđelković’s song Three Kisses, declared the biggest music hit of 2009 in Serbia.

BEYOND THE MYTH OF THE POP SINGER. ARTICULATION AND RECEPTION OF NEW RHETORICAL BODIES: THE CASE OF LOS PUNSETES

Full Text Available There is a relationship between musical performance and body movement (Palmer, 1997. Visual perception of musicians can influence the reception of the work by the audience, even more decisive than through hearing (Juchniewicz, 2008. In the case of women singers in live events, the spectacle of one's body through nonverbal language and music is not particularly plausible, and often refers to sexuality (Davidson, 2005, Koskoff, 1989. In this exploratory study we have considered the implications and the visual impact of the proposal of a pop singer contrary to the norm. Through content analysis and interviews with the public in a concert of The Punsetes Madrid group, it follows the subversive nature of their singer and performer. This subversion works on an immediate level, through the frustration of the expectations of the audience.

Full Text Available The article deals with the iconography of the illustration of the Second Paschal Homily of St. Gregory of Nazianzus on fol. 285r of the Paris manuscript. It questions the identity of the woman saint represented on the right of St. Paraskeve in the lower register of the scene. Unlike that above St. Paraskeve, the inscription identifying this second woman saint is fragmentary and difficult to read, but it has been widely accepted that she is Saint Helena, mother of the Emperor Constantine the Great. On the basis of two other representations of Helena in the same manuscript and of the style of the inscription accompanying them, as well as taking into account the importance of the theological meaning expounded by St. Gregory in his oration, it is suggested that the second woman saint may be St. Kyriake.

An instrument to measure differential pore pressures in deep ocean sediments: Pop-Up-Pore-Pressure-Instrument (PUPPI)

International Nuclear Information System (INIS)

Schultheiss, P.J.; McPhail, S.D.; Packwood, A.R.; Hart, B.

1985-01-01

A Pop-Up-Pore-Pressure-Instrument (PUPPI) has been developed to measure differential pore pressures in sediments. The differential pressure is the pressure above or below normal hydrostatic pressure at the depth of the measurement. It is designed to operate in water depths up to 6000 metres for periods of weeks or months, if required, and measures differential pore pressures at depths of up to 3 metres into the sediments with a resolution of 0.05 kPa. It is a free-fall device with a lance which penetrates the sediments. This lance and the ballast weight is disposed when the PUPPI is acoustically released from the sea floor. When combined with permeability and porosity values of deep-sea sediments the pore pressure measurements made using the PUPPI suggest advection velocities as low as 8.8 mm/yr. The mechanical, electrical and acoustic systems are described together with data obtained from both shallow and deep water trials. (author)

Atmospheric levels of 43 PCBs, 22 OCPs, and 14 PBDEs were determined in 16 cities at urban and rural sites by passive sampling to generate the first large-scale nationwide dataset of POP residues in Turkey's atmosphere. Sampling campaign was performed from May 2014 to April 2015 with three-month sampling periods at locations on east-west and north-south transects through the country to investigate seasonal and spatial variations, including long range atmospheric transport (LRAT). Factor analysis was conducted to infer on the potential sources. Overall average Σ43PCBs concentration was 108 ± 132 pg/m3. PCB-118 (26.3 ± 44.6 pg/m3) was the top congener, and penta-CBs had the highest contribution with 54.3%. ΣDDTs had the highest annual mean concentration with 134 ± 296 pg/m3 among the OCP groups among which the highest concentration compound was p'p-DDE (97.6 ± 236 pg/m3). Overall average concentration of Σ14PBDEs was 191 ± 329 pg/m3 with the highest contribution from BDE-190 (42%). Comparison of OCPs and PCBs concentrations detected at temperatures which were above and below annual average temperature indicated higher concentrations in the warmer periods, hence significance of secondary emissions for several OCPs and Σ43PCBs, as well as inference as LRAT from secondary emissions. The first nationwide POPs database constructed in this study, point to current use, local secondary emissions, and LRAT for different individual compounds, and indicate the need for regular monitoring.

2006-01-01

Polychlorinated biphenyls (PCBs) and organic pesticides (i.e., DDTs) were measured in long finned eels (Anguilla dieffenbachii) in 17 streams on the west coast of South Island, New Zealand. Very low levels of PCBs and low levels of ppDDE were found. The concentrations of PCBs and ppDDE were not correlated within sites indicating that different processes determined the levels of the two pollutants in New Zealand eels. The PCBs probably originate from atmospheric transport, ppDDE levels are determined by land use and are higher in agriculture areas. The low contamination level of these aquatic systems seems to be a function of a low input from both long and short-range transport as well as few local point sources. No correlation could be found between lipid content and persistent organic pollutants (POPs) concentration (as shown in previous studies) in the eels which could be explained by low and irregular intake of the pollutants. - Low levels of PCBs found in New Zealand eels reflect isolation from atmospheric sources while DDTs levels are determined by land use

A novel experimental approach for the determination of the photooxidative decay of semivolatile pesticides and POPs adsorbed on single levitated particles; Aufbau eines Messverfahrens zum photo-oxidativen Abbau von semivolatilen Pflanzenschutzmitteln und POPs an levitierten Einzelpartikeln

2002-08-01

A novel experimental approach has been developed that permits to measure in the laboratory the atmospheric decay of low volatile, particle-bound compounds (pesticides, persistent organic pollutants (POP)) which react efficiently with OH-radicals in the atmosphere. The experimental approach makes use of trapped micro- and nanoparticles which are coated by monolayers of the low volatile compounds. Trapping is accomplished by storing the particles in an electrodynamic trap, which is surrounded by a controlled atmosphere. The temperature, pressure, humidity, and the chemical composition of the atmosphere can be adjusted to the atmospheric environment of interest. The particles can be exposed to reactive trace gases, such as OH radicals or ozone. The chemically induced changes of the adsorbates are time-resolved monitored by Raman spectroscopy. As a result, chemical processes, reaction products, as well as evaporation from the particle surface can be investigated. Alternatively, Fourier-transform infrared spectroscopy can be used for the detection of such time resolved processes. The experiments allow us to derive kinetic data of particle-bound low volatile compounds. We have constructed and characterized all devices and components that are required for this novel experimental approach. This included a suitable particle trap, sources of OH radicals, and the efficient detection of time-resolved Raman spectra of stored particles. The components were commissioned by using simple, but realistic test systems. Raman spectra of particle-bound pesticides were measured and first kinetic experiments were performed. The setup is now ready to use for systems of environmental interest. (orig.)

Impact of multi-layer soil model on the simulation of persistent organic pollutant fate at european scale

International Nuclear Information System (INIS)

Loizeau, Vincent

2014-01-01

Persistent Organic Pollutants (POPs) are toxic substances that bio-accumulate in the food chain. Once emitted in the atmosphere, they are transported by the wind and deposited on soil. Since they are persistent, they can be re-emitted from soil to atmosphere by volatilization and travel over very long distances. This process is called grasshopper effect. Thus, POPs may be found at significant levels far from their emission source. It is necessary to understand the transport and fate of these pollutants in order to support the decision making process and reduce human exposure to POPs. Regulations over the last decades lead to a decrease of anthropogenic emissions and subsequent decrease of atmospheric concentration. In this context, the soil is no longer a sink of POPs but can be a source to the atmosphere. Many numeric models aim to study the behavior of POPs in the environment. Most of them consider soil compartment as a homogeneous box, leading to an underestimation of re-emissions. Then, it appears of great importance to develop more realistic soil models. The objective of my thesis was to develop such a model, with vertical transport within the soil. This model was evaluated against measured concentration soil profile. We also conducted a sensitivity analysis to identify the key parameters involved in the process of re-emissions. Then, the soil model was coupled with an atmospheric transport model. A case study was finally undertaken to estimate the impacts of re-emissions on global-mass balance of POPs at European scale. (author) [fr

Multiple Stressors in a Top Predator Seabird: Potential Ecological Consequences of Environmental Contaminants, Population Health and Breeding Conditions.

Full Text Available Environmental contaminants may have impacts on reproduction and survival in wildlife populations suffering from multiple stressors. This study examined whether adverse effects of persistent organic pollutants (POPs increased with poor population health and breeding conditions in three colonies (60-74°N of great skua (Stercorarius skua in the north-eastern Atlantic (Shetland, Iceland and Bjørnøya [Bear Island]. POPs (organochlorines [OCs] and polybrominated diphenyl ethers [BDEs] were measured in plasma of incubating birds (n = 222, concentrations differing nearly tenfold among colonies: Bjørnøya (2009 > Bjørnøya (2010 > Iceland (2009 > Shetland (2009. Reproductive success (hatching success and chick survival showed that breeding conditions were favourable in Shetland and at Bjørnøya (2010, but were very poor in Iceland and at Bjørnøya (2009. Biomarkers indicated that health was poor in the Shetland population compared to the other populations. Females whose chicks hatched late had high POP concentrations in all colonies except at Bjørnøya (2010, and females losing their eggs at Bjørnøya (2009 tended to have higher concentrations than those hatching. Moreover, there was a negative relationship between female POP concentrations and chick body condition at hatching in Iceland and at Bjørnøya (2010. Supplementary feeding experiments were conducted, and in Iceland where feeding conditions were poor, significant negative relationships were found between female POP concentrations and daily growth-rate in first-hatched chicks of control nests, but not in food supplemented nests. This suggests that negative impacts of POPs were mitigated by improved feeding conditions. For second-chicks, there was a strong negative relationship between the female POP concentrations and growth-rate, but no effects of supplementary feeding. Lowered adult return-rate between breeding seasons with increasing POP loads were found both at Bjørnøya (2009 and

Ciceronas apie vertimą. Ką mums atskleidžia žodžių reikšmės | Cicero about Translation: Exploring the Meaning of Words

Full Text Available The author of the article reveals Cicero’s attitude towards translation, exploring some passages from his rhetorical and philosophical treatises which deal with translation from Greek to Latin, and paying most attention to the usage of words with the mean­ing “translate, translator”.To conclude, the regular Latin verb for “to trans­late” (convertere in Cicero’s usage implies neither the accuracy or literalism of translation. For a close literal translation he uses interpretari or such ex­pressions as ad verbum (verbum de verbo verbum e verbo, ad verbum exprimere, verbum pro verbo reddere. The verbs exprimere, explicare, reddere are used more or less metaphorically to express various aspects of translation from Greek, which includes also a free interpretation of the original and borrow­ing some elements from the original. According to our observations, Fin. I. 7 is the only case in Cicero’s extant scripts, as well as the first in Latin literature, when the verb transferre, while meaning “to trans­fer, to borrow, to use in context” comes closest to vertere. By contrast, the authors of I–II AD, such as Seneca, Pliny the Elder and the Younger, Quintilian use the word transferre with the meaning of transla­tion quite regularly.We argue that when Cicero calls himself not in­terpres, sed orator, he tries to indicate first of all not the closeness or freedom of translation, but rather the rhetorical power of his text. He is not afraid to use a word in not a very common sense, or two words for one in the original, or to create a new one if necessary, which may seem too bold for the interpretes indiserti not so skilled and well-trained in rhetorics. Cicero approached his work of translation without any pre­conceived rules, and the main standard referred to is his own taste based on the ruling principle of rhetor­ics – decorum, aptum, prepon – i.e. appropriateness. Cicero, as a translator as well as an orator, matches every

Grapheme-colour synaesthesia improves detection of embedded shapes, but without pre-attentive 'pop-out' of synaesthetic colour.

Science.gov (United States)

Ward, Jamie; Jonas, Clare; Dienes, Zoltan; Seth, Anil

2010-04-07

For people with synaesthesia letters and numbers may evoke experiences of colour. It has been previously demonstrated that these synaesthetes may be better at detecting a triangle made of 2s among a background of 5s if they perceive 5 and 2 as having different synaesthetic colours. However, other studies using this task (or tasks based on the same principle) have failed to replicate the effect or have suggested alternative explanations of the effect. In this study, we repeat the original study on a larger group of synaesthetes (n = 36) and include, for the first time, an assessment of their self-reported colour experiences. We show that synaesthetes do have a general advantage over controls on this task. However, many synaesthetes report no colour experiences at all during the task. Synaesthetes who do report colour typically experience around one third of the graphemes in the display as coloured. This is more consistent with theories of synaesthesia in which spatial attention needs to be deployed to graphemes for conscious colour experiences to emerge than the interpretation based on 'pop-out'.

Long-range transport of persistent organic pollutant (POPs) is a global concern. Remote regions such as the Southern Ocean are greatly under-sampled though critical components in understanding POPs cycling. Over 20 high-volume air samples were collected in the Southern Ocean aboard the RV Brown during the GASEX III experiment between Mar 05 to April 9 2008. The relatively stationary platform (51S,38W) enabled the collection of a unique atmospheric time series at this open ocean station. Air sampling was also conducted across transects from Punto Arenas, Chile and to Montevideo, Uruguay. Samples were collected using glass sleeves packed with poly-urethane foam plugs and C-18 resin in order to collect target organic pollutants (per-fluorinated compounds, currently and historically used pesticides) in this under-sampled region. Here we present POPs concentrations and trends over the sampled period and compare variations with air parcel back trajectories to establish potential origins of their long-range transport.

The great intimidators.

Kramer, Roderick M

2006-02-01

After Disney's Michael Eisner, Miramax's Harvey Weinstein, and Hewlett-Packard's Carly Fiorina fell from their heights of power, the business media quickly proclaimed thatthe reign of abrasive, intimidating leaders was over. However, it's premature to proclaim their extinction. Many great intimidators have done fine for a long time and continue to thrive. Their modus operandi runs counter to a lot of preconceptions about what it takes to be a good leader. They're rough, loud, and in your face. Their tactics include invading others' personal space, staging tantrums, keeping people guessing, and possessing an indisputable command of facts. But make no mistake--great intimidators are not your typical bullies. They're driven by vision, not by sheer ego or malice. Beneath their tough exteriors and sharp edges are some genuine, deep insights into human motivation and organizational behavior. Indeed, these leaders possess political intelligence, which can make the difference between paralysis and successful--if sometimes wrenching--organizational change. Like socially intelligent leaders, politically intelligent leaders are adept at sizing up others, but they notice different things. Those with social intelligence assess people's strengths and figure out how to leverage them; those with political intelligence exploit people's weaknesses and insecurities. Despite all the obvious drawbacks of working under them, great intimidators often attract the best and brightest. And their appeal goes beyond their ability to inspire high performance. Many accomplished professionals who gravitate toward these leaders want to cultivate a little "inner intimidator" of their own. In the author's research, quite a few individuals reported having positive relationships with intimidating leaders. In fact, some described these relationships as profoundly educational and even transformational. So before we throw out all the great intimidators, the author argues, we should stop to consider what

In recent years reporting requirements regarding emissions and releases of unintentionally formed persistent organic pollutants (POPs) have been laid on parties to international agreements and members of the EU. Such obligations include those under the Stockholm Convention on Persistent Organic Pollutants, the UNECE POP and PRTR protocols and the EU PRTR regulation. The aim of this project has been to assess, whether existing knowledge and data are adequate for the Nordic countries to be able to estimate the emissions eventually to be reported. The project reveals that there is a substantial lack of knowledge related to potential sources in the Nordic countries. It also suggests that even though many of the main potential sources are the same, the relative importance of them differs between countries. (au)

What great managers do.

Science.gov (United States)

Buckingham, Marcus

2005-03-01

Much has been written about the qualities that make a great manager, but most of the literature overlooks a fundamental question: What does a great manager actually do? While there are countless management styles, one thing underpins the behavior of all great managers. Above all, an exceptional manager comes to know and value the particular quirks and abilities of her employees. She figures out how to capitalize on her staffers' strengths and tweaks her environment to meet her larger goals. Such a specialized approach may seem like a lot of work. But in fact, capitalizing on each person's uniqueness can save time. Rather than encourage employees to conform to strict job descriptions that may include tasks they don't enjoy and aren't good at, a manager who develops positions for his staff members based on their unique abilities will be rewarded with behaviors that are far more efficient and effective than they would be otherwise. This focus on individuals also makes employees more accountable. Because staffers are evaluated on their particular strengths and weaknesses, they are challenged to take responsibility for their abilities and to hone them. Capitalizing on a person's uniqueness also builds a stronger sense of team. By taking the time to understand what makes each employee tick, a great manager shows that he sees his people for who they are. This personal investment not only motivates individuals but also galvanizes the entire team. Finally, this approach shakes up existing hierarchies, which leads to more creative thinking. To take great managing from theory to practice, the author says, you must know three things about a person: her strengths, the triggers that activate those strengths, and how she learns. By asking the right questions, squeezing the right triggers, and becoming aware of your employees' learning styles, you will discover what motivates each person to excel.

By using space vector algebra method, the vertex of great ellipse is solved directly, and description of great ellipse based on major-axis vector and minor-axis vector is presented. Then calculation formulas of great ellipse azimuth and distance are deduced using two basic vectors. Finally, algorithms of great ellipse route planning are studied, especially equal distance route planning algorithm based on Newton-Raphson(N-R method. Comparative examples show that the difference of route planning between great circle and great ellipse is significant, using algorithms of great ellipse route planning can eliminate the navigation error caused by the great circle route planning, and effectively improve the accuracy of navigation calculation.

Full Text Available Maize is primarily grown as an energy crop, but the use of different specific versions, such as high-oil maize, high-lysine maize, waxy maize, white-seeded maize, popping maize and sweet maize, is quite extensive. Speciality maize, due to its traits and genetic control of these traits, requires a particular attention in handling breeding material during the processes of breeding. It is especially related to prevention of uncontrolled pollination. In order to provide successful selection for a certain trait, the following specific procedures in evaluation of the trait are necessary: the estimation of a popping volume and flake quality in popping maize; the determination of sugars and harvest maturity in sweet maize; the determination of oil in selected samples of high-oil maize types, and so forth. Breeding programmes for speciality maize, except high-amylose maize, have been implemented at the Maize Research Institute, Zemun Polje, Belgrade, for the last 45 years. A great number of high-yielding sweet maize hybrids, popping maize, high-oil and high-lysine, flint and white-seeded maize hybrids were developed during this 45-year period. Auspicious selection and breeding for these traits is facilitated by the abundant genetic variability and technical and technological possibilities necessary for successful selection.

Climate variability and Great Plains agriculture

International Nuclear Information System (INIS)

Rosenberg, N.J.; Katz, L.A.

1991-01-01

The ways in which inhabitants of the Great Plains, including Indians, early settlers, and 20th century farmers, have adapted to climate changes on the Great Plains are explored. The climate of the Great Plains, because of its variability and extremes, can be very stressful to plants, animals and people. It is suggested that agriculture and society on the Great Plains have, during the last century, become less vulnerable to the stresses imposed by climate. Opinions as to the sustainability of agriculture on the Great Plains vary substantially. Lockeretz (1981) suggests that large scale, high cost technologies have stressed farmers by creating surpluses and by requiring large investments. Opie (1989) sees irrigation as a climate substitute, however he stresses that the Ogallala aquifer must inevitably become depleted. Deborah and Frank Popper (1987) believe that farming on the Plains is unsustainable, and destruction of shelterbelts, out-migration of the rural population and environmental problems will lead to total collapse. With global warming, water in the Great Plains is expected to become scarcer, and although improvements in irrigation efficiency may slow depletion of the Ogallala aquifer, ultimately the acreage under irrigation must decrease to levels that can be sustained by natural recharge and reliable surface flows. 23 refs., 2 figs

Equilibrium Passive Sampling of POP in Lipid-Rich and Lean Fish Tissue: Quality Control Using Performance Reference Compounds.

Science.gov (United States)

Rusina, Tatsiana P; Carlsson, Pernilla; Vrana, Branislav; Smedes, Foppe

2017-10-03

Passive sampling is widely used to measure levels of contaminants in various environmental matrices, including fish tissue. Equilibrium passive sampling (EPS) of persistent organic pollutants (POP) in fish tissue has been hitherto limited to application in lipid-rich tissue. We tested several exposure methods to extend EPS applicability to lean tissue. Thin-film polydimethylsiloxane (PDMS) passive samplers were exposed statically to intact fillet and fish homogenate and dynamically by rolling with cut fillet cubes. The release of performance reference compounds (PRC) dosed to passive samplers prior to exposure was used to monitor the exchange process. The sampler-tissue exchange was isotropic, and PRC were shown to be good indicators of sampler-tissue equilibration status. The dynamic exposures demonstrated equilibrium attainment in less than 2 days for all three tested fish species, including lean fish containing 1% lipid. Lipid-based concentrations derived from EPS were in good agreement with lipid-normalized concentrations obtained using conventional solvent extraction. The developed in-tissue EPS method is robust and has potential for application in chemical monitoring of biota and bioaccumulation studies.

The present work deals-for environmental importance with the estimation of radioelement contents 238 U, 226 Ra, 232 Th and 40 K in non fertilized soil, fertilized soil (crops), fertilized soil (vegetables) and samples from the bottoms of the local drainage systems collected from four sites (Govern orates) of egyptian delta. This work therefore aims at assessing eventual concentration and build up of the natural-radioactivity in the Egyptian soil treated by the locally produced single superphosphate fertilizer and phosphogypsum. A total number (42) of samples were collected from the following sites (Govern orates); 1) El-Qalyobia (Shebin El-Qanater and Abu-Zaabal); 2) El-Sharqia (Inshas and Minia El-kamh); 3) El-Dakahlia (El-Mansoura); and 4) El-Menoufia (Tala). From each locality two samples of non-fertilized soil, two samples of non-fertilized soil, two samples of fertilized soil (crops), two samples of fertilized soil (vegetables), and sample the drainage system were obtained.

1995-05-01

This article works from the premise that these poems form part o f a tradition that can he traced back to the funerary poetry of the Dutch Renaissance and from there to the funeral orations of Classical times. After referring to the current revival of interest in rhetoric, attention is given to the role which rhetoric played in Renaissance poetics and the influence it had on the practice of writing funerary poetry. The funerary poems in Cloete's Allotroop are then analysed, making use of the Renaissance descriptions of and prescriptions for funerary poetry researched by S.F. Witstein in Funeraire poëzie in de Nederlandse Renaissance. These analyses prove that Cloete’s poems make use of the elements basic to the Renaissance funerary poem and the classical funeral oration namely praise (laus, mourning (luctus and consolation (consolatio and that the rhetorical terminology devised centuries ago can still be useful in the reading of these poems.

La retórica aristotélica y la oratoria de su tiempo (sobre el ejemplo de Lisias III

Full Text Available Aristotle's Rhetoric is a descriptive text to a greater extent than normally recognised and so our understanding of Aristotle can be improved with the analysis of speeches previous to him; as a case study, the third speech of Lysias has been chosen. The argumentation of judicial speeches previous to Aristotle was built with enthymemes whose first premises are based on emotions and characters explaining human behaviour; therefore the first purpose of Rhetoric 11.2-11 (about emotions and 11.2-17 (about characters was to supply the orators with first premises. In those speeches the emotions of the audience were stirred up by enthymemes; therefore Aristotle accepted that the orator could use emotions in this rational and logic way. Nevertheless he condemned the arousing of emotions by direct and irrational requests, a procedure found in the judicial speeches. This way the apparent contradictory treatment of emotions in Aristotle's Rhetoric can be solved.

The pilot whale Globicephala melas, the sperm whale Physeter macrocephalus, and the fin whale Balaenoptera physalus are large cetaceans permanently inhabiting the Mediterranean Sea. These species are subjected to numerous anthropogenic threats such as exposure to high levels of contaminants. Therefore, selected persistent organic pollutants POPs (29 PCBs, 15 organochlorine compounds, 9 PBDEs and 17 PCDD/Fs) were analysed in blubber biopsies of 49 long-finned pilot whales, 61 sperm whales and 70 fin whales sampled in the North Western Mediterranean Sea (NWMS) from 2006 to 2013. Contamination profile and species feeding ecology were then combined through the use of stable isotopes. δ{sup 13}C, δ{sup 15}N values and POPs levels were assessed through IR-MS and GC–MS respectively. To assess the toxic potency of the dioxin-like compounds, the TEQ approach was applied. δ{sup 15}N values were 12.2±1.3‰ for sperm whales, 10.5±0.7‰ for pilot whales and 7.7±0.8‰ in fin whales, positioning sperm whales at higher trophic levels. δ{sup 13}C of the two odontocetes was similar and amounted to −17.3±0.4‰ for sperm whales and −17.8±0.3‰ for pilot whales; whilst fin whales were more depleted (−18.7±0.4‰). This indicates a partial overlap in toothed-whales feeding habitats, while confirms the differences in feeding behaviour of the mysticete. Pilot whales presented higher concentrations than sperm whales for ΣPCBs (38,666±25,731 ng g{sup −1} lw and 22,849±15,566 ng g{sup −1} lw respectively), ΣPBDEs (712±412 ng g{sup −1} lw and 347±173 ng g{sup −1} lw respectively) and ΣDDTs (46,081±37,506 ng g{sup −1} lw and 37,647±38,518 ng g{sup −1} lw respectively).

This is called irrelevant sound effect, which means that the presence of irrelevant sound significantly impairs people's performance on main visual task. Some researchers believe that the reason of this phenomenon is because the lyrics of the background pop music add extra workload to the working memory, which interferes with the visual task. Moreover, it was shown that the first language lyrics impaired participants' performance more seriously than a strange language. To participants, the second language is less familiar than the first language but more than a strange language. So how about the irrelevant sound effect when lyrics are participants' second language? And how about it when the visual task contains the second language? This study aimed to investigate the influence of different language lyrics to the visual memory task, the familiarity of whose materials was different in two experiments. It was hypothesized that there

Great magnetic storms

Tsurutani, B.T.; Yen Te Lee; Tang, F.; Gonzalez, W.D.

1992-01-01

The five largest magnetic storms that occurred between 1971 and 1986 are studied to determine their solar and interplanetary causes. All of the events are found to be associated with high speed solar wind streams led by collisionless shocks. The high speed streams are clearly related to identifiable solar flares. It is found that (1) it is the extreme values of the southward interplanetary magnetic fields rather than solar wind speeds that are the primary causes of great magnetic storms, (2) shocked and draped sheath fields preceding the driver gas (magnetic cloud) are at least as effective in causing the onset of great magnetic storms (3 of 5 events ) as the strong fields within the driver gas itself, and (3) precursor southward fields ahead of the high speed streams allow the shock compression mechanism (item 2) to be particularly geoeffective

The accounting model was used as a utility model for assessing the cumulative health effects to the general population residing in the downstream regional water basin as a result of the disposal of LLW when a unit response analysis method is used. The utility model is specifically designed to assess the cumulative population health effects in conjunction with the PRESTO-EPA-POP, PRESTO-EPA-BRC, or PRESTO-EPA-DEEP model simply for the purpose of reducing the cost of analysis. Therefore, the assessment of the cumulative population health effects may also be conducted with one of the above appropriate models without the aid of this accounting model

Thirty years of great ape gestures.

Science.gov (United States)

Tomasello, Michael; Call, Josep

2018-02-21

We and our colleagues have been doing studies of great ape gestural communication for more than 30 years. Here we attempt to spell out what we have learned. Some aspects of the process have been reliably established by multiple researchers, for example, its intentional structure and its sensitivity to the attentional state of the recipient. Other aspects are more controversial. We argue here that it is a mistake to assimilate great ape gestures to the species-typical displays of other mammals by claiming that they are fixed action patterns, as there are many differences, including the use of attention-getters. It is also a mistake, we argue, to assimilate great ape gestures to human gestures by claiming that they are used referentially and declaratively in a human-like manner, as apes' "pointing" gesture has many limitations and they do not gesture iconically. Great ape gestures constitute a unique form of primate communication with their own unique qualities.

["Great jobs"-also in psychiatry?].

Science.gov (United States)

Spiessl, H; Hübner-Liebermann, B

2003-09-01

Against the background of a beginning shortage of psychiatrists, results from interviews with 112 employees of an automotive company with the topic "Great Job" are presented to discuss their relevance to psychiatry. The interviews were analysed by means of a qualitative content analysis. Most employees assigned importance to great pay, constructive collaboration with colleagues, and work appealing to personal interests. Further statements particularly relevant to psychiatry were: successful career, flexible working hours, manageable job, work-life balance, well-founded training, no bureaucracy within the company, and personal status in society. The well-known economic restrictions in health care and the still negative attitude towards psychiatry currently reduce the attraction of psychiatry as a profession. From the viewpoint of personnel management, the attractors of a great job revealed in this study are proposed as important clues for the recruitment of medical students for psychiatry and the development of psychiatric staff.

Pacific salmonines in the Great Lakes Basin

2012-01-01

Pacific salmon (genus Oncorhynchus) are a valuable resource, both within their native range in the North Pacific rim and in the Great Lakes basin. Understanding their value from a biological and economic perspective in the Great Lakes, however, requires an understanding of changes in the ecosystem and of management actions that have been taken to promote system stability, integrity, and sustainable fisheries. Pacific salmonine introductions to the Great Lakes are comprised mainly of Chinook salmon, coho salmon, and steelhead and have accounted for 421, 177, and 247 million fish, respectively, stocked during 1966-2007. Stocking of Pacific salmonines has been effective in substantially reducing exotic prey fish abundances in several of the Great Lakes (e.g., lakes Michigan, Huron, and Ontario). The goal of our evaluation was to highlight differences in management strategies and perspectives across the basin, and to evaluate policies for Pacific salmonine management in the Great Lakes. Currently, a potential conflict exists between Pacific salmonine management and native fish rehabilitation goals because of the desire to sustain recreational fisheries and to develop self-sustaining populations of stocked Pacific salmonines in the Great Lakes. We provide evidence that suggests Pacific salmonines have not only become naturalized to the food webs of the Great Lakes, but that their populations (specifically Chinook salmon) may be fluctuating in concert with specific prey (i.e., alewives) whose populations are changing relative to environmental conditions and ecosystem disturbances. Remaining questions, however, are whether or not “natural” fluctuations in predator and prey provide enough “stability” in the Great Lakes food webs, and even more importantly, would a choice by managers to attempt to reduce the severity of predator-prey oscillations be antagonistic to native fish restoration efforts. We argue that, on each of the Great Lakes, managers are pursuing

The present study compares concentrations and chemical profiles of an extended range of persistent organic pollutants (dioxins, polychlorobiphenyls, brominated flame retardants and organochlorine pesticides) in breast milk samples from French (n = 96), Danish (n = 438) and Finnish (n = 22) women....... Median exposure levels observed in French women (WHO-TEQ2005 PCDD/F = 6.1 pg/g l.w., WHO-TEQ2005 dl-PCB = 4.3 pg/g l.w., sum of 6 ndl-PCB = 85.2 ng/g l.w., sum of 7 i-PBDE = 1.5 ng/g l.w.) appeared overall lower than in Danish and Finnish women for all examined POPs, except for α-HBCD (2-fold higher...... level at 0.6 ng/g l.w.). Furthermore, the observed exposure levels of dioxins and PCBs were higher in Danish women (WHO-TEQ2005 PCDD/F = 13.2 pg/g l.w., WHO-TEQ2005 dl-PCB = 6.6 pg/g l.w., sum of 6 ndl-PCB = 162.8 ng/g l.w.) compared to Finnish women (WHO-TEQ2005 PCDD/F = 9.0 pg/g l.w., WHO-TEQ2005 dl...

Toxaphene and mirex are the members of persistent organic pollutants (POPs) included in the International Treaty, the Stockholm Convention. POPs are characteristically transferred across borders and are accumulated in wildlife. Consequently, their global distribution and biological impacts are of great concern. However, there is very little information on contamination by toxaphene and mirex in the Asia-Pacific region. In Japan, scientific research focused on these two pesticides has not been conducted so far since they have never been registered there. In this study, toxaphene and mirex were determined in the blubber of cetaceans collected from various regions with a focus on Asian countries to evaluate the effects of their long-range atmospheric transport from regions where they were extensively used.

Great Lakes rivermouths: a primer for managers

Between the North American Great Lakes and their tributaries are the places where the confluence of river and lake waters creates a distinct ecosystem: the rivermouth ecosystem. Human development has often centered around these rivermouths, in part, because they provide a rich array of ecosystem services. Not surprisingly, centuries of intense human activity have led to substantial pressures on, and alterations to, these ecosystems, often diminishing or degrading their ecological functions and associated ecological services. Many Great Lakes rivermouths are the focus of intense restoration efforts. For example, 36 of the active Great Lakes Areas of Concern (AOCs) are rivermouths or areas that include one or more rivermouths. Historically, research of rivermouth ecosystems has been piecemeal, focused on the Great Lakes proper or on the upper reaches of tributaries, with little direct study of the rivermouth itself. Researchers have been divided among disciplines, agencies and institutions; and they often work independently and use disparate venues to communicate their work. Management has also been fragmented with a focus on smaller, localized, sub-habitat units and socio-political or economic elements, rather than system-level consideration. This Primer presents the case for a more holistic approach to rivermouth science and management that can enable restoration of ecosystem services with multiple benefits to humans and the Great Lakes ecosystem. A conceptual model is presented with supporting text that describes the structures and processes common to all rivermouths, substantiating the case for treating these ecosystems as an identifiable class.1 Ecological services provided by rivermouths and changes in how humans value those services over time are illustrated through case studies of two Great Lakes rivermouths—the St. Louis River and the Maumee River. Specific ecosystem services are identified in italics throughout this Primer and follow definitions described

The concentrations and bioaccumulation of persistent organic pollutants (POPs) were determined in four fish species from Lake Koka, Ethiopia, representing 2–3 levels in the food chain of the lake. Dichlorodiphenyltrichloroethanes (DDTs), endosulfans, polychlorinated biphenyls (PCBs) and chlorpyrifos were identified, with DDTs as the most predominant pesticide, with concentration ranging from 0.05 to 72.53 ng g −1 wet weight (ww). All fish tissue samples collected from different species of the lake contained residues of DDTs. The maximum level of DDTs was found in the fattiest, African sharptooth catfish (Clarias gariepinus) sampled from the lake, with a mean concentration of 15.15 ng g −1 ww. The significant (P 15 N indicates that DDTs biomagnified in the food web of the lake. The 4,4′-DDE to 4,4′-DDT ratio in Oreochromis niloticus (0.6) and Cyprinus carpio (0.5) were below 1, indicating ongoing use of DDTs in the study area and recent exposure of these fish species.
