Full Text Available  Celem artykułu było ustalenie, czy informacje o wolontariuszach ujawniane przez organizacje non-profit prowadzące działalność pożytku publicznego w Polsce są porównywalne oraz czy pozwalają ocenić wpływ wolontariatu na wyniki finansowe tych organizacji. Na podstawie badań literaturowych wskazano możliwości wyceny wartości wolontariatu w sprawozdaniach organizacji pożytku publicznego w Polsce i na świecie. Postawiony cel był realizowany poprzez studia literaturowe oraz badania empiryczne z wykorzystaniem metod analizy statystycznej na próbie 315 fundacji w Polsce. Studia literaturowe wykazały wiele barier związanych z pomiarem pracy wolontariuszy i jej raportowaniem, co uniemożli-wia przy obecnym stanie wiedzy oraz nastawieniu menedżerów organizacji non-profit uwzględnienie tej informacji w sprawozdaniach finansowych. Badania empiryczne wykazały natomiast niedostateczność informacji o pracy wolontariuszy w sprawozdaniach merytorycznych fundacji w Polsce. Prezentowana informacja nie pozwala na ocenę wpływu wolontariatu na wyniki osiągane przez fundacje, ani na porów-nywanie tych informacji pomiędzy organizacjami.

Janusz KONKOL

Full Text Available W artykule przedstawiono wyniki optymalizacji składu betonu modyfikowanego dodatkiem prażonego kaolinitu (metakaolinitu, użytego jako częściowy substytut cementu. Optymalizację przeprowadzono przy użyciu programu STATISTICA w oparciu o wyniki badań betonów o zróżnicowanym składzie, zdeterminowanym udziałem dodatku metakaolinitu do 15% masy spoiwa oraz stosunkiem woda/spoiwo od 0,35 do 0,54. Badania wykonano według centralnego kompozycyjnego planu doświadczenia, przewidującego wykonanie badań dziewięciu mieszanek betonowych o zróżnicowanym składzie. Jako kryteria optymalizacji przyjęto: maksimum wytrzymałości na ściskanie fc po 28, 90 i 180 dniach dojrzewania betonu, maksimum krytycznego współczynnika intensywności naprężeń KIcS i maksimum współczynnika sprężystości podłużnej E po 28 i 180 dniach dojrzewania betonu, minimum objętości porów powietrznych w betonie A oraz minimalny wymiar fraktalny określony metodą cięciwy DC i metodą pudełkową DBC. Objętość porów powietrznych określono na podstawie analizy płaskich przekrojów betonu metodami stereologicznymi. Analizie fraktalnej poddano uzyskane w badaniu odporności na pękanie powierzchnie przełomów betonów. Optymalizację przeprowadzono dla trzech wariantów I, II i III. Uzyskane wyniki potwierdziły występowanie ścisłej zależności między właściwościami a strukturą betonów, w tym betonów z dodatkiem metakaolinitu. Wykazano także, że ze względu na przyjęte kryteria optymalizacji celowe jest projektowanie betonów przy założeniu względnie niskiego stosunku woda/spoiwo oraz względnie dużego udziału dodatku metakaolinitu.

2015-12-01

Full Text Available Artykuł stanowi zarazem historyczne, jak i systematyczne oraz problemowe wprowadzenie do teorii kapitalizmu kognitywnego. Rekonstruuje najważniejsze stanowiska i debaty w danym polu, od pierwszych publikacji na temat prac niematerialnych oraz postfordyzmu przez analizy kryzysu finansowego 2001 roku po najnowsze publikacje teoretyków i teoretyczek kapitalizmu kognitywnego. Systematyzuje rozproszone w debacie nad kapitalizmem kognitywnym analizy, od wzrastającej roli efektów zewnętrznych i renty we współczesnym kapitalizmie, przez przekształcenia intelektu powszechnego po wykształcenie się nowych form wartości i nowych mechanizmów jej akumulacji. To właśnie to ostatnie zagadnienie, nowe mechanizmy akumulacji wartości, stanowi główny problem, na którym skupia się artykuł. Ukazując funkcje kapitału finansowego w ukształtowaniu się kapitalizmu kognitywnego jako pewnego reżimu akumulacji, artykuł nie tylko analizuje kapitalizm kognitywny jako niestabilny reżim akumulacji, ale stara się w systematyczny sposób przedstawić sprzeczności tegoż reżimu akumulacji.

Celem artykułu jest weryfikacja tej hipotezy. Wykorzystano (a oceny osiągnięć uczniów wystawione przez nauczycieli poza procesem nauczania (dla celów badawczych i (b wyniki standaryzowanych testów osiągnięć z języka polskiego. Analizy uwzględniające potencjalną stronniczość pozycji testowych ze względu na płeć ucznia przeprowadzono metodą modelowania wielu wskaźników i wielu przyczyn (MIMIC. Wykorzystano dane pochodzące z ogólnopolskiego badania 4144 uczniów trzeciej klasy szkoły podstawowej. Zgodnie z przewidywaniami, nauczyciele wyżej oceniali osiągnięcia dziewczynek niż chłopców, ale ta różnica zanikła, gdy do modelu analizy włączono wyniki standaryzowanych testów. Okazuje się więc, że nauczyciele potrafią bezstronnie ocenić osiągnięcia szkolne z języka polskiego dziewczynek i chłopców.

Full Text Available Znajomość przepływu brzegowego jest istotna dla przeprowadziania prac inżynierskich na wybranych odcinkach rzek. Celem niniejszego artykułu jest wyznaczenie przepływu brzegowego na rzece Powie przy wykorzystaniu wzorów empirycznych. Wybrana rzeka ma charakter nizinny. W badaniach porównywano wartości przepływu brzegowego uzyskiwane dla warunków przed odmuleniem i po odmuleniu rzeki. Wykorzystano w tym celu pomiary przekrojów poprzecznych wykonane w latach 2007 oraz 2014 na odcinku powyżej zbiornika Stare Miasto. Wybrany odcinek rzeki jest niekontrolowany, ponieważ najbliższy wodowskaz zlokalizowano poniżej zbiornika. Obliczenia wykonano w trzech etapach. W pierwszym kroku obliczenia przeprowadzono dla wybranych przekroi za pomocą dwóch wzorów empirycznych – Wolmana oraz Williamsa. W drugim wykonano obliczenia za pomocą programu HEC-RAS i zweryfikowano wcześniej uzyskane wartości poprzez porównanie z wynikami symulacji. Trzeci etap obejmował połączenie modelowania z wynikami uzyskanymi na podstawie wzorów empirycznych. Wyniki porównano ze sobą w pięciu wybranych przekrojach. Na podstawie wykonanych obliczeń stwierdzono dość znaczne rozbieżności pomiędzy zastosowanymi metodami. Wyniki przedstawione w artykule nie dają jednoznacznej odpowiedzi na pytanie, która z tych metod jest właściwa.

Full Text Available Artykuł prezentuje wyniki badania dotyczącego związku funkcji wykonawczych i powodzenia szkolnego. W badaniu udział wzięło 46 dzieci w wieku 7 i 8 lat, uczniów pierwszej klasy szkoły podstawowej. W zakresie funkcji wykonawczych dokonano pomiaru dwóch ich przejawów: elastyczności poznawczej i zdolności tworzenia pojęć. Do ich pomiaru użyto dwóch narzędzi, z których jedno zostało stworzone na podstawie testu sortowania kart Wisconsin. Dla drugiego pierwowzorem był dwuwymiarowy test sortowania kart. W celu zbadania powodzenia szkolnego dokonano jego pomiaru z trzech różnych perspektyw: uczniów, nauczycieli i rodziców. Powodzenie szkolne z perspektywy uczniów i rodziców badano narzędziami stworzonymi na podstawie ankiety powodzenia szkolnego autorstwa Anny Żurawskiej (wywiad z uczniami, kwestionariusz dla rodziców;, trzecim wskaźnikiem powodzenia były oceny szkolne. Wyniki wskazują na istotne znaczenie funkcji wykonawczych w zakresie elastyczności poznawczej dla powodzenia szkolnego (część z uzyskanych wyników osiąga poziom istotności statystycznej. Natomiast w zakresie drugiego z przejawów funkcji wykonawczych, czyli zdolności tworzenia pojęć, związek z powodzeniem szkolnym zaobserwowano jedynie w przypadku pomiaru dokonywanego wśród uczniów.

Full Text Available Celem opracowania jest identyfikacja wysokości i zróżnicowania opodatkowania pracy, wyrażanego poprzez tzw. klin podatkowy, w Polsce na tle krajów OECD. Identyfikacji tej dokonano na podstawie analizy danych statystycznych zgromadzonych w bazie OECD obejmujących lata 2000-2012. W opracowaniu dokonano interpretacji pojęć kluczowych, takich jak opodatkowanie pracy, klin podatkowy i pozapłacowe koszty pracy. W dalszej części syntetycznie omówiono ustalenia teoretyczne i wyniki badań empirycznych dotyczących skutków opodatkowania pracy dla funkcjonowania rynku pracy, a zwłaszcza jego wpływ na zatrudnienie i bezrobocie. Badania własne objęły analizę porównawczą wielkości klina podatkowego w różnych typach gospodarstw domowych w Polsce i pozostałych krajach OECD w latach 2000-2012. Najważniejszą konstatacją wynikającą z analiz jest, iż w Polsce opodatkowanie pracy w zbyt małym stopniu uwzględnia sytuację materialną osób nisko zarabiających oraz mających nautrzymaniu dzieci. Wyniki przeprowadzonych badań stały się podstawą sformułowania wniosków syntetycznych i rekomendacji dla Polski. Zasugerowano w nich przede wszystkim, by rozważono selektywne obniżenie pozapłacowych kosztów pracy osób nisko zarabiających oraz obciążonych obowiązkami rodzinnymi.

  Streszczenie   Wstęp Menopauza to naturalny etap życia każdej kobiety. Zmiany hormonalne zachodzące w organizmie w tym okresie powodują często wiele dolegliwości. Jedną z metod łagodzenia objawów menopauzy jest stosowanie hormonalnej terapii zastępczej, jak również przestrzeganie zachowań sprzyjających zdrowiu. Hormonalna terapia zastępcza łagodzi objawy menopauzy, ale także niesie za sobą pewne zagrożenia, które można minimalizować poprzez zachowania prozdrowotne. Cel badań  Celem badań była ocena zachowań zdrowotnych kobiet w okresie około menopauzalnym. Materiał i Metody W niniejszej pracy przebadano 50 kobiet w przedziale wiekowym 45-63 lata (średnia wieku 52,8 lat, które podzielono na 3 grupy w zależności od występowania objawów menopauzalnych i stosowania hormonalnej terapii zastępczej. Wyniki W badanej grupie kobiet w okresie menopauzalnym wykazano przeciętny poziom zachowań zdrowotnych. W całej badanej grupie najwyższe wyniki uzyskano w kategorii „zachowania profilaktyczne”, najniższe w kategoriach „prawidłowe nawyki żywieniowe” i „praktyki zdrowotne”. Porównując wyniki między grupami nie wykazano różnic istotnych statystycznie.   Summary   Introduction Menopause is a natural stage of life of every woman. The hormonal changes that occur the body often cause a lot of discomfort. One method of alleviating the symptoms of menopause is hormone replacement therapy, as well as the observance of behavior conducive to health. Hormone replacement therapy eases the symptoms of menopause, but also entails certain risks, which can be minimized by health behaviors. The aim of the study The aim of this reaserch was to present health behaviours of women in perimenopausal age. Material and Methods In this reaserch, 50 women in the age range 45-63 years old (average age 52,8 were examined and divided into 3 groups according to their menopausal symptoms and the use of hormonal replacement therapy.

Full Text Available W niniejszym artykule autorzy badają relacje między dwoma podejściami do planowania – partycypa-cyjnym i odgórnym – a przepływami informacji zarządczych w przedsiębiorstwach w ramach controllin-gu. W uzupełnieniu dotychczasowych rozważań teoretycznych i badań empirycznych prezentowanych w literaturze zwracają oni uwagę na partycypacyjność planowania nie tylko w ujęciu operacyjnym, ale też strategicznym. Wyniki prezentowane w artykule odnoszą się do dwóch badań prowadzonych w okre-sach od listopada 2010 r. do stycznia 2012 r. oraz od listopada 2013 r. do stycznia 2014 r. Badania prze-prowadzono w Polsce odpowiednio w 397 i 179 przedsiębiorstwach. Autorzy sformułowali dwie hipote-zy łączące planowanie partycypacyjne z przepływami informacyjnymi inicjowanymi odgórnie i oddolnie. Wartykule zastosowano podejście ilościowe, w tym analizę korelacji rang oraz aglomerację metodą Warda, które pozwoliły na analizy porównawcze nie tylko w odniesieniu do różnych podgrup organizacjiujętych w obu próbkach badawczych, ale także na porównania w czasie. Uzyskane wyniki potwierdziły pozytywny wpływ planowania partycypacyjnego na przepływy informacji zarządczych, zarówno te inicjowane odgórnie, jak i oddolnie. W szczególności planowanie partycypacyjne pozwala ograniczyć asymetrię informacyjną między kierownictwem naczelnym a pracownikami poszczególnych komórek funkcjonalnych.

Full Text Available W artykule przedstawiono wyniki badań z wykorzystaniem wysokorozdzielczej mikrotomografii komputerowej (μCT zastosowanej w celu uzyskania obrazu struktury wewnętrznej gruntu. Wyniki prześwietlań μCT zostały wykorzystane do selekcji miarodajnych próbek do badań, a także do oceny zmian struktury w analizie pełzania gruntu podczas badań trójosiowych. Badania przeprowadzono na pastach gruntowych wykonanych z iłów mio-polioceńskich pobranych z Warszawy oraz próbkach NNS mioceńskiego iłołupka pochodzącego z zapadliska przedkarpackiego. Pierwszą serię badań przeprowadzono na iłowych pastach gruntowych, a następnie na iłołupkach, prowadząc standardowe badania typu CU z określeniem maksymalnych parametrów wytrzymałościowych oraz naprężeń niszczących wykorzystywanych w późniejszych badaniach pełzania. W kolejnym etapie badań, z wykorzystaniem próbek wstępnie przebadanych w mikrotomografie, przeprowadzono badania pełzania gruntu w aparacie trójosiowego ściskania przy naprężeniach osiowych nieprzekraczających maksymalnej wartości dewiatora naprężenia. Na podstawie uzyskanych obrazów struktury wewnętrznej gruntu określono typy zniszczeń w poszczególnych próbkach oraz obliczono zawartość szczelin naturalnych i pozniszczeniowych. Dodatkowo uzyskano trójwymiarowe modele próbek, które można wykorzystać do dalszych symulacji badań laboratoryjnych. Obrazy 2D i 3D wewnętrznej struktury gruntów spoistych stwarzają nowe możliwości w poznawaniu procesów zmian właściwości gruntów.

Niezależne obliczenia przepływów potencjalnych i zredukowanych przeprowadzono za pomocą modelu SWMM, który jest modelem dynamicznym o parametrach rozłożonych. Obliczone za pomocą modeli HEC-RAS i SWMM przepływy zredukowane o prawdopodobieństwach przekroczenia 1, 2 i 10% są do siebie podobne w przekrojach obliczeniowych II, III i IV – w 7. na 9 przypadków różnice w przepływach nie przekraczają 25%. Największe wartości przepływów zredukowanych o określonym prawdopodobieństwie przekroczenia obliczono w przekroju II, przy zastosowaniu obydwu modeli. Przepływy zredukowane są mniejsze od przepływów potencjalnych obliczonych za pomocą modeli OTTHYMO i SWMM. Wyniki obliczeń wskazują na możliwość stosowania w zlewniach miejskich zarówno modelu HEC-RAS, jak i modelu SWMM.

Na stężenie substancji toksycznych w dymie papierosowym w sposób oczywisty wpływać muszą warunki tlenowo-temperaturowe generowania dymu. Warunki te zależne są od sposobu palenia papierosa (topografii palenia). Topografię palenia charakteryzują następujące parametry: głębokość i szybkość zaciągania, czas przerw między zaciągnięciami i liczba zaciągnięć. W zdecydowanej większości dotychczasowych badań dotyczących składu dymu papierosowego, dym generowano w standardowych warunkach zalecanych przez Międzynarodową Organizację Normalizacyjną ISO i Federalną Komisję Handlu FTC. Obecnie coraz częściej kwestionuje się wykorzystanie standardowych metod laboratoryjnych, jako narzędzi do oceny dawek substancji toksycznych pobieranych przez palaczy w wyniku palenia Określenie rzeczywistych dawek substancji odtytoniowych na jakie narażeni są palacze określonej populacji wymaga zatem w pierwszej kolejności określenia topografii palenia palaczy należących do tej populacji. Celem pracy była kompleksowa charakterystyka parametrów topografii palenia papierosów populacji palaczy w Polsce i jej rozkładu statystycznego. Do badań zakwalifikowano reprezentatywną grupę 129 palaczy. Aby spełnić założenia reprezentatywności badanej grupy palących dokonano analizy struktury demograficznej palaczy papierosów w Polsce posługując się danymi GUS dotyczącymi ogólnej struktury ludności (płeć, profil wiekowy) oraz szczegółowej struktury populacji palaczy papierosów przeprowadzonych według kryteriów profilu wiekowego i liczby wypalanych papierosów. Pomiar indywidualnych parametrów topografii palenia przeprowadzono przy pomocy profesjonalnego przenośnego urządzenia CreSSmicro. Średnia objętość zaciągania się dymem zmierzona w badanej grupie wynosiła 60 ml, była, więc 78% wyższa od wartości normatywnej zalecanej do badań przez ISO (35 ml). Średnia szybkość zaciągania mierzona w badanej populacji wynosząca 48 ml/s jest aż o 120% wyższa od wartości zalecanej przez ISO (17,5 ml/s). Także wyznaczony średni czas trwania zaciągnięcia wynoszący 1,7 s różnił się od wartości zalecanej przez ISO równej 2s, choć w mniejszym stopniu niż inne parametry (13,2%). Mierzony czas przerw pomiędzy poszczególnymi zaciągnięciami wynoszący średnio 20 s jest aż 3-krotnie niższy od czasu standardowego (ISO), wynoszącego 60 s. Badając zmienność objętości kolejnych zaciągnięć podczas wypalania papierosa stwierdzono, że w miarę występowania kolejnych zaciągnięć następuje spłycenie ich objętości. Wszystkie mierzone parametry topografii palenia charakteryzowały się dużym rozrzutem w obrębie badanej populacji. PMID:19189573

The Experiment Factory: standardizing behavioral experiments

Directory of Open Access Journals (Sweden)

Vanessa V Sochat

2016-04-01

Full Text Available The administration of behavioral and experimental paradigms for psychology research is hindered by lack of a coordinated effort to develop and deploy standardized paradigms. While several frameworks (de Leeuw (2015; McDonnell et al. (2012; Mason and Suri (2011; Lange et al. (2015 have provided infrastructure and methods for individual research groups to develop paradigms, missing is a coordinated effort to develop paradigms linked with a system to easily deploy them. This disorganization leads to redundancy in development, divergent implementations of conceptually identical tasks, disorganized and error-prone code lacking documentation, and difficulty in replication. The ongoing reproducibility crisis in psychology and neuroscience research (Baker (2015; Open Science Collaboration (2015 highlights the urgency of this challenge: reproducible research in behavioral psychology is conditional on deployment of equivalent experiments. A large, accessible repository of experiments for researchers to develop collaboratively is most efficiently accomplished through an open source framework. Here we present the Experiment Factory, an open source framework for the development and deployment of web-based experiments. The modular infrastructure includes experiments, virtual machines for local or cloud deployment, and an application to drive these components and provide developers with functions and tools for further extension. We release this infrastructure with a deployment (http://www.expfactory.org that researchers are currently using to run a set of over 80 standardized web-based experiments on Amazon Mechanical Turk. By providing open source tools for both deployment and development, this novel infrastructure holds promise to bring reproducibility to the administration of experiments, and accelerate scientific progress by providing a shared community resource of psychological paradigms.

Beare, A.N.; Gray, L.H.

1984-01-01

During the FY83 research, a simulator experiment was conducted at the control room simulator for a GE Boiling Water Reactor (BWR) NPP. The research subjects were licensed operators undergoing requalification training and shift technical advisors (STAs). This experiment was designed to investigate the effects of senior reactor operator (SRO) experience, operating crew augmentation with an STA and practice, as a crew, upon crew and individual operator performance, in response to anticipated plant transients. Sixteen two-man crews of licensed operators were employed in a 2 x 2 factorial design. The SROs leading the crews were split into high and low experience groups on the basis of their years of experience as an SRO. One half of the high- and low-SRO experience groups were assisted by an STA. The crews responded to four simulated plant casualties. A five-variable set of content-referenced performance measures was derived from task analyses of the procedurally correct responses to the four casualties. System parameters and control manipulations were recorded by the computer controlling the simulator. Data on communications and procedure use were obtained from analysis of videotapes of the exercises. Questionnaires were used to collect subject biographical information and data on subjective workload during each simulated casualty. For four of the five performance measures, no significant differences were found between groups led by high (25 to 114 months) and low (1 to 17 months as an SRO) experience SROs. However, crews led by low experience SROs tended to have significantly shorter task performance times than crews led by high experience SROs. The presence of the STA had no significant effect on overall team performance in responding to the four simulated casualties. The FY84 experiments are a partial replication and extension of the FY83 experiment, but with PWR operators and simulator

Patrycja PRAŻMO

Full Text Available Charakterystyka prądowo-napięciowa to podstawowa forma prezentacji parametrów elektrycznych ogniwa fotowoltaicznego. Wykres krzywej I-V modułu PV zmienia się w ciągu dnia w zależności od natężenia promieniowania słonecznego oraz temperatury modułu. Artykuł przedstawia pomiary krzywych I-V w warunkach oświetlenia sztucznego wykonanych autorskim urządzeniem. W skład układu pomiarowego oprócz urządzenia wchodził również komputer sterujący wraz z oprogramowaniem Arduino w celu kontroli procesu pomiaru oraz zapisu odczytu danych do pliku. Spośród różnych dostępnych metod pomiarowych do realizacji urządzenia wybrano metodę pojemnościową wykorzystującą proces ładowania kondensatora do zmiany rezystancji układu od zera do nieskończoności. Taka metoda pomiaru nie umożliwia odtworzenia krzywej od punktu zwarcia i wymaga ekstrapolacji wyników, natomiast wykorzystuje ona stosunkowo łatwy w konstrukcji układ elektroniczny a także nie jest ona kosztowna. Urządzenie mierzy napięcie poprzez wbudowany konwerter ADC porównując badane napięcie z napięciem referencyjnym oraz natężenie prądu w obwodzie wykorzystując czujnik natężenia oparty o efekt Halla. W pracy porównano rezultaty pomiarów dla dwóch różnych typów ogniw fotowoltaicznych: polikrystalicznego i monokrystalicznego ogniwa krzemowego. Otrzymane wyniki zaprezentowano w formie wykresów. Porównano na nich wyniki dla kilku pomiarów oraz wartości uśrednionych. Porównano obliczone wartości współczynnika wypełnienia, który określa stosunek mocy maksymalnej ogniwa rzeczywistego do mocy maksymalnej ogniwa idealnego z danymi podanymi przez producenta.

Słowianek Marta

2016-03-01

Full Text Available Wstęp: Przyprawy dodawane do żywności wzbogacają jej walory smakowe i zapachowe, niektóre z nich mogą także wydłużać jej czas przechowywania dzięki obecności związków o aktywności przeciwutleniającej. Cel: Celem pracy było zbadanie 28 przypraw dostępnych na rynku pod kątem całkowitej zawartości polifenoli i aktywności przeciwutleniającej. Metody: Do oceny całkowitej zawartości związków fenolowych zastosowano metodę Folina- Ciocalteau. Aktywność antyoksydacyjną ekstraktów oznaczono metodą z użyciem rodnika DPPH. Wyniki: Otrzymane wyniki wykazują, że większość analizowanych przypraw jest bogata w związki fenolowe i posiada wysoką aktywność antyoksydacyjną. Całkowita zawartość polifenoli w przyprawach oscylowała od 0,9 do 155,1 mg GAE/g z najniższą wartością odnotowaną dla sezamu i najwyższą dla cynamonu. Zdolność do wygaszania rodnika DPPH wyrażona w procentach była zróżnicowana i wahała się w zakresie od 4,1% dla sezamu do 94,9% dla goździków. Odnotowano umiarkowaną korelację (r=0,63, p<0,05 pomiędzy aktywnością antyoksydacyjną i zawartością polifenoli ogółem, co dowodzi, że związki fenolowe są ważnymi, antyoksydacyjnymi składnikami w badanych przyprawach. Wnioski: Prowadzone badania wykazują, że wiele przypraw może służyć jako naturalne konserwanty żywności i jednocześnie ma korzystny wpływ na nasze zdrowie.

Zmiany sprawności funkcji poznawczych w trakcie suplementacji wielonienasyconymi kwasami tłuszczowymi omega-3 w grupie chorych na schizofrenię – przegląd systematyczny

Full Text Available Deficyt w obszarze funkcjonowania poznawczego jest stałym fenomenem opisywanym w populacji osób z rozpoznaniem schizofrenii – w okresie przedchorobowym, w trakcie pogorszeń, jak również między kolejnymi epizodami. Zaburzenie funkcjonowania poznawczego stanowi niezależny czynnik rokowniczy w schizofrenii. Badania wskazują, że właśnie od tego wymiaru patologii zależą takie wykładniki funkcjonowania pacjentów, jak: wyniki leczenia i rehabilitacji, współpraca w leczeniu, funkcjonowanie zawodowe, rodzinne i społeczne, zdolność do samodzielnej egzystencji oraz jakość życia. Dotychczasowe metody leczenia schizofrenii nie zapewniają wystarczającej poprawy w zakresie tego wymiaru choroby. W okresie ostatnich 25 lat testowano użyteczność wielonienasyconych kwasów tłuszczowych omega-3 jako monoterapii oraz jako augmentacji leczenia przeciwpsychotycznego w schizofrenii. Uzyskane wyniki są niejednoznaczne, choć podkreśla się tzw. pozytywny trend uzyskiwanych wyników w zakresie poprawy objawowej. Stosunkowo rzadko oceniano wpływ suplementacji preparatami wielonienasyconych kwasów tłuszczowych omega-3 na funkcjonowanie poznawcze osób z rozpoznaniem schizofrenii. Korzystny wpływ suplementacji wielonienasyconymi kwasami tłuszczowymi na funkcjonowanie poznawcze ma uzasadnienie teoretyczne. Wśród znanych działań tych substancji mogących wpływać na usprawnienie funkcji poznawczych należy wymienić: działanie immunomodulacyjne w obrębie ośrodkowego układu nerwowego, poprawę parametrów stresu oksydacyjnego, zmiany w zakresie neurotransmisji oraz wpływ na procesy plastyczności neuronalnej. Celem niniejszej pracy jest przedstawienie systematycznego przeglądu wyników badań dotyczących zmian sprawności funkcjonowania poznawczego u osób z rozpoznaniem schizofrenii będących w trakcie suplementacji wielonienasyconymi kwasami tłuszczowymi omega-3.

Full Text Available Wstęp: W Diagnostic and Statistical Manual of Mental Disorders (DSM-5 zespół jedzenia nocnego zaklasyfikowany został do innych specyficznych zaburzeń odżywiania. Szacuje się, że zespół ten dotyczy około 1,5% populacji; częstość występowania postaci rodzinnej nie jest znana. Materiał i metody: Wykorzystano Kwestionariusz Jakości Snu Pittsburgh, Mini-Addenbrooke’s Cognitive Examination, Test Figury Złożonej Reya–Osterrietha, Test Łączenia Punktów A i B, Test 15 słów Reya, Inwentarz Depresji Becka, Inwentarz Stanu i Cechy Lęku oraz swobodne techniki diagnostyczne. Opis przypadku: W artykule zaprezentowano przypadek 35-letniej pacjentki hospitalizowanej z powodu zaburzeń snu i epizodów objadania się w nocy występujących od około 15 lat. Nie stwierdzono objawów depresyjnych, lękowych, wytwórczych ani objawów świadczących o anoreksji czy bulimii. W badaniu neurologicznym nie odnotowano odchyleń od staniu prawidłowego, co potwierdziły badanie obrazowe głowy z kontrastem, badanie elektroencefalograficzne i badania biochemiczne. Wywiad rodzinny wskazywał na występowanie podobnych objawów u dwóch członków rodziny. Wyniki: Wyniki badania psychologicznego potwierdziły obniżenie jakości snu, a także pogorszenie funkcjonowania poznawczego w aspekcie krótkotrwałej pamięci werbalnej i zdolności koncentracji uwagi oraz obniżenie poziomu fluencji semantycznej w wąskim zakresie. Wnioski: Po przeprowadzeniu diagnostyki różnicowej ustalono rozpoznanie rodzinnej postaci zespołu jedzenia nocnego. Zważywszy na rzadkość omawianego schorzenia w populacji, potrzebne jest pogłębienie badań dotyczących tej postaci zespołu.

Full Text Available Wprowadzenie: Najważniejszą obiektywną metodą oceny zaburzeń układu równowagi jest badanie oczopląsu. Badanie kaloryczne jako jedyny test obrazuje pobudliwość poszczególnych błędników, umożliwiając ocenę każdego z nich osobno. Cel pracy: Celem pracy jest analiza porównawcza wyników badania oczopląsu kalorycznego uzyskanych przy użyciu metody ENG i VNG u osób zdrowych. Materiał i metody: Badaniami objęto grupę 20 osób zdrowych, w tym 10 kobiet i 10 mężczyzn w wieku 22-26 lat. U wszystkich chorych przeprowadzono badanie podmiotowe oraz badanie przedmiotowe otoneurologiczne, badanie ENG i w odstępie 7-dniowym badanie VNG z kalibracją, oceną oczopląsu samoistnego oraz próbami kalorycznymi wg Hallpike’a. Test kaloryczny wykonano kalorymetrem powietrznym firmy HOMOTH, używając temperatury powietrza 30°C oraz 44°C, podawanych przez 40 s do ucha. Wyniki: W teście kalorycznym u żadnej osoby nie stwierdzono deficytu kanałowego wykraczającego poza granice przyjętych norm. Zaobserwowano niższe wartości średnie maksymalnej prędkości wolnej fazy oczopląsów w badaniu ENG niż VNG. Ponadto badanie VNG dodatkowo umożliwiło wyznaczenie wartości przewagi kierunkowej bezwzględnej oraz średniej pobudliwości błędników. Wnioski: Uzyskane wyniki wskazują, iż badanie VNG w stosunku do badania ENG jest bardziej precyzyjne i umożliwia dokładniejsze opisanie próby kalorycznej wg Hallpike’a. W badaniu VNG analiza parametru przewagi kierunkowej bezwzględnej znacznie podnosi wartość próby kalorycznej wg Hallpike’a.

Full Text Available W pracy przedstawiono wyniki badań nad wpływem rozpuszczalnika na właściwości ieologiczne i sposób przygotowania zawiesin ceramicznych. Pokazano, że w przypadku zastosowanej żywicy poliestrowej woda nie może być użyta do przygoto- wania światłoutwardzalnej zawiesiny ceramicznej. Jednakże stężona zawiesina ceramiczna może być otrzymana jeżeli woda zostanie zastąpiona glikolem polietylenowym. W ten sposób możliwe jest przygotowanie zawiesiny o stężeniu fazy stałym dochodzącym do 45-50%obj. i dobrej jednorodności oraz lepkości, pozwalającej na jej formowanie metodą odlewania cienkiej folii ceramicznej i utwardzenie promieniowaniem UV.

Kulinowski, Piotr

2014-03-01

This article deals with a methodology developed to design and select tensioning systems with using simulation studies on a belt conveyor model. It describes the structure of a dynamic model of a belt conveyor with distributed parameters and details of physical models of the applied belt tensioning systems. For proper display and comparison of work described tensioning systems are shown examples of the results of simulations carried out on a discrete model of the mining belt conveyor. Presented methodology has been verified through industrial research and realization of a number of complex projects requiring simulation tests of take-up systems of belt conveyors. W artykule przedstawiono symulacyjną metodę projektowania i doboru układów napinania taśmy, wykorzystującą wyniki badań modelowych, będącą często wymaganym rozszerzeniem stosowanych analitycznych metod obliczeniowych (Kulinowski, 2013b). Z uwagi na zjawiska falowe występujące w taśmie podczas nieustalonych stanów pracy przenośników taśmowych, rozruchu, hamowania i pracy przy zmiennej ilości nadawy, wyniki obliczeń uzyskane z wykorzystaniem standardowych metod obliczeniowych można uznać jedynie za szacunkowe lub wstępne do przeprowadzenia badań symulacyjnych. Charakter rozruchu przenośnika taśmowego zależy od typu zastosowanego urządzenia rozruchowego i napinającego, mas wprowadzanych w ruch oraz od własności sprężystych taśmy. Problemy związane z analizą pracy układów napędowych i urządzeń napinających podczas rozruchu przenośników cięgnowych rozwiązano z wykorzystaniem modelu dyskretnego o parametrach rozłożonych (Dolipski et al., 2012; Kulinowski, 2012) opisanego w pierwszej części publikacji. Badania symulacyjne przeprowadzone na takim modelu umożliwiają ocenę pracy przenośnika taśmowego wykorzystującego taśmę z rdzeniem tkaninowym lub stalowym, dlatego też kolejny rozdział artykułu poświęcono modelom reologicznym taśm przeno

1985-01-01

Experiments are being conducted on nuclear power plant (NPP) control room training simulators by the Oak Ridge National Laboratory, its subcontractor, General Physics Corporation, and participating utilities. The experiments are sponsored by the Nuclear Regulatory Commission's (NRC) Human Factors and Safeguards Branch, Division of Risk Analysis and Operations, and are a continuation of prior research using simulators, supported by field data collection, to provide a technical basis for NRC human factors regulatory issues concerned with the operational safety of nuclear power plants. During the FY83 research, a simulator experiment was conducted at the control room simulator for a GE boiling water reactor (BWR) NPP. The research subjects were licensed operators undergoing requalification training and shift technical advisors (STAs). This experiment was designed to investigate the effects of (a) senior reactor operator (SRO) experience, (b) operating crew augmentation with an STA and (c) practice, as a crew, upon crew and individual operator performance, in response to anticipated plant transients. The FY84 experiments are a partial replication and extension of the FY83 experiment, but with PWR operators and simulator. Methodology and results to date are reported

The TRIO experiment is a test of in-situ tritium recovery and heat transfer performance of a miniaturized solid breeder blanket assembly. The assembly (capsule) was monitored for temperature and neutron flux profiles during irradiation and a sweep gas flowed through the capsule to an anaytical train wherein the amounts of tritium in its various chemical forms were determined. The capsule was designed to operate at different temperatures and sweep gas conditions. At the end of the experiment the amount of tritium retained in the solid was at a concentration of less than 0.1 wppM. More than 99.9% of tritium generated during the experiment was successfully recovered. The results of the experiment showed that the tritium inventories at the beginning and at the end of the experiment follow a relationship which appears to be characteristic of intragranular diffusion

2002-03-01

This is a databook of TRACY ''ramp withdrawal'' experiments. TRACY is a reactor to perform supercritical experiments using low-enriched uranyl nitrate aqueous solution. The excess reactivity of TRACY is 3$ at maximum, and it is inserted by feeding the solution to a core tank or by withdrawing a control rod, which is called as the transient rod, from the core. In the ramp withdrawal experiment, the supercritical experiment is initiated by withdrawing the transient rod from the core in a constant speed using a motor drive system. The data in the present databook consist of datasheets and graphs. Experimental conditions and typical values of measured parameters are tabulated in the datasheet. In the graph, power and temperature profiles are plotted. Those data are useful for the investigation of criticality accidents with fissile solutions, and for validation of criticality accident analysis codes. (author)

1977-04-01

A computer analysis, using the WHAM and RELAP4 computer codes, was performed to predict the LOFT system thermal-hydraulic response for Experiment L1-4 of the nonnuclear (isothermal) test series. Experiment L1-4 will simulate a 200 percent double-ended offset shear in the cold leg of a four-loop large pressurized water reactor. A core simulator will be used to provide a reactor vessel pressure drop representative of the LOFT nuclear core. Experiment L1-4 will be initiated with a nominal isothermal primary coolant temperature of 282.2 0 C, a pressurizer pressure of 15.51 MPa, and a primary coolant flow of 270.9 kg/s. In general, the predictions of saturated blowdown for Experiment Ll-4 are consistent with the expected system behavior, and predicted trends agree with results from Semiscale Test S-01-4A, which simulated the Ll-4 experiment conditions

Abstract: This chapter introduces a psycho-societal approach to theorizing learning, combining a materialist theory of socialization with a hermeneutic interpretation methodology. The term "approach" indicates the intrinsic connection between theory, empirical research process and epistemic subject....... Learning is theorized as dynamic subjective experience of (socially situated) realities, counting on individual subjectivity as well as subjective aspects of social interaction. This psycho-societal theory of subjective experiences conceptualizes individual psychic development as interactional experience...... of societal relations, producing an inner psycho-dynamic as a conscious and unconscious individual resource in future life. The symbolization of immediate sensual experiences form an individual life experience of social integration, language use being the medium of collective, social experience (knowledge...

In the graph, power and temperature profiles are plotted. Those data are useful for the investigation of criticality accidents with fissile solutions, and for validation of criticality accident analysis codes. (author)

The difference between traditional experiments and CFD validation benchmark experiments

Computation Fluid Dynamics provides attractive features for design, and perhaps licensing, of nuclear power plants. The most important of these features is low cost compared to experiments. However, uncertainty of CFD calculations must accompany these calculations in order for the results to be useful for important decision making. In order to properly assess the uncertainty of a CFD calculation, it must be “validated” against experimental data. Unfortunately, traditional “discovery” experiments are normally ill-suited to provide all of the information necessary for the validation exercise. Traditionally, experiments are performed to discover new physics, determine model parameters, or to test designs. This article will describe a new type of experiment; one that is designed and carried out with the specific purpose of providing Computational Fluid Dynamics (CFD) validation benchmark data. We will demonstrate that the goals of traditional experiments and validation experiments are often in conflict, making use of traditional experimental results problematic and leading directly to larger predictive uncertainty of the CFD model.

Acute adverse psychological reactions to classic hallucinogens ("bad trips" or "challenging experiences"), while usually benign with proper screening, preparation, and support in controlled settings, remain a safety concern in uncontrolled settings (such as illicit use contexts). Anecdotal and case reports suggest potential adverse acute symptoms including affective (panic, depressed mood), cognitive (confusion, feelings of losing sanity), and somatic (nausea, heart palpitation) symptoms. Responses to items from several hallucinogen-sensitive questionnaires (Hallucinogen Rating Scale, the States of Consciousness Questionnaire, and the Five-Dimensional Altered States of Consciousness questionnaire) in an Internet survey of challenging experiences with the classic hallucinogen psilocybin were used to construct and validate a Challenging Experience Questionnaire. The stand-alone Challenging Experience Questionnaire was then validated in a separate sample. Seven Challenging Experience Questionnaire factors (grief, fear, death, insanity, isolation, physical distress, and paranoia) provide a phenomenological profile of challenging aspects of experiences with psilocybin. Factor scores were associated with difficulty, meaningfulness, spiritual significance, and change in well-being attributed to the challenging experiences. The factor structure did not differ based on gender or prior struggle with anxiety or depression. The Challenging Experience Questionnaire provides a basis for future investigation of predictors and outcomes of challenging experiences with classic hallucinogens. © The Author(s) 2016.

Experiment Databases

Science.gov (United States)

Vanschoren, Joaquin; Blockeel, Hendrik

Next to running machine learning algorithms based on inductive queries, much can be learned by immediately querying the combined results of many prior studies. Indeed, all around the globe, thousands of machine learning experiments are being executed on a daily basis, generating a constant stream of empirical information on machine learning techniques. While the information contained in these experiments might have many uses beyond their original intent, results are typically described very concisely in papers and discarded afterwards. If we properly store and organize these results in central databases, they can be immediately reused for further analysis, thus boosting future research. In this chapter, we propose the use of experiment databases: databases designed to collect all the necessary details of these experiments, and to intelligently organize them in online repositories to enable fast and thorough analysis of a myriad of collected results. They constitute an additional, queriable source of empirical meta-data based on principled descriptions of algorithm executions, without reimplementing the algorithms in an inductive database. As such, they engender a very dynamic, collaborative approach to experimentation, in which experiments can be freely shared, linked together, and immediately reused by researchers all over the world. They can be set up for personal use, to share results within a lab or to create open, community-wide repositories. Here, we provide a high-level overview of their design, and use an existing experiment database to answer various interesting research questions about machine learning algorithms and to verify a number of recent studies.

My name is Nicoara Floarea and I am teacher at Secondary School Calatele and I teach students from preparatory class and the second grade . They are six-eight years old. In my activity, for introducing scientific concepts to my students, I use various and active methods or traditional methods including experiments. The experiment stimulates students' curiosity, their creativity, the understanding and knowledge taught accessibility. I propose you two such experiments: The life cycle of the plants (long-term experiment, with rigorous observation time):We use beans, wheat or other; They are grown in pots and on the cotton soaked with water,keeping under students' observation protecting them ( just soak them regularly) and we waiting the plants rise. For discussions and comments of plant embryo development we use the plants which rose on the cotton soaked with water plants at the end of the first week. Last school year we had in the pot climbing beans which in May made pods. They were not too great but our experiment was a success. The students could deduce that there will develop those big beans which after drying will be planted again. The influence of light on plants (average duration experiment with the necessary observation time): We use two pots in which plants are of the same type (two geraniums), one of them is situated so as to get direct sunlight and other plant we put in a closed box. Although we wet both plants after a week we see that the plant that benefited from sunlight has turned strain in direct sunlight, developing normally in return the plant out of the box I have yellowed leaves, photosynthesis does not She has occurred . Students will understand the vital role of the Sun in plants' life, both in the classroom and in nature. The experiment is a method of teaching students extremely pleasant, with a remarkable percentage of acquiring more knowledge.

Experiments in computing: a survey.

Experiments play a central role in science. The role of experiments in computing is, however, unclear. Questions about the relevance of experiments in computing attracted little attention until the 1980s. As the discipline then saw a push towards experimental computer science, a variety of technically, theoretically, and empirically oriented views on experiments emerged. As a consequence of those debates, today's computing fields use experiments and experiment terminology in a variety of ways. This paper analyzes experimentation debates in computing. It presents five ways in which debaters have conceptualized experiments in computing: feasibility experiment, trial experiment, field experiment, comparison experiment, and controlled experiment. This paper has three aims: to clarify experiment terminology in computing; to contribute to disciplinary self-understanding of computing; and, due to computing's centrality in other fields, to promote understanding of experiments in modern science in general.

Experience in Design and Learning Approaches – Enhancing the Framework for Experience

Directory of Open Access Journals (Sweden)

Merja L.M. Bauters

2017-06-01

Full Text Available In design and learning studies, an increasing amount of attention has been paid to experience. Many design approaches relate experience to embodiment and phenomenology. The growth in the number of applications that use the Internet of Things (IoT has shifted human interactions from mobile devices and computers to tangible, material things. In education, the pressure to learn and update skills and knowledge, especially in work environments, has underlined the challenge of understanding how workers learn from reflection while working. These directions have been fuelled by research findings in the neurosciences, embodied cognition, the extended phenomenological–cognitive system and the role of emotions in decision-making and meaning making. The perspective on experience in different disciplines varies, and the aim is often to categorise experience. These approaches provide a worthwhile view of the importance of experience in learning and design, such as the recent emphasis on conceptual and epistemological knowledge creation. In pragmatism, experience plays a considerable role in research, art, communication and reflection. Therefore, I rely on Peirce’s communicative theory of signs and Dewey’s philosophy of experience to examine how experience is connected to reflection and therefore how it is necessarily tangible.

Popper's Thought Experiment Reinvestigated

Richardson, Chris; Dowling, Jonathan

2012-02-01

Karl Popper posed an interesting thought experiment in 1934. With it, he meant to question the completeness of quantum mechanics. He claimed that the notion of quantum entanglement leads to absurd scenarios that cannot be true in real life and that an implementation of his thought experiment would not give the results that QM predicts. Unfortunately for Popper, it has taken until recently to perform experiments that test his claims. The results of the experiments do not refute QM as Popper predicted, but neither do they confirm what Popper claimed QM predicted. Kim and Shih implemented Popper's thought experiment in the lab. The results of the experiment are not clear and have instigated many interpretations of the results. The results show some correlation between entangled photons, but not in the way that Popper thought, nor in the way a simple application of QM might predict. A ghost-imaging experiment by Strekalov, et al. sheds light on the physics behind Popper's thought experiment, but does not try to directly test it. I will build the physics of Popper's thought experiment from the ground up and show how the results of both of these experiments agree with each other and the theory of QM, but disprove Popper.

Every 21st century student is expected to develop science literacy skills. As this is not part of Serbian national curriculum yet, we decided to introduce it with this project. Experiment-o-mania provides students to experience science in different and exciting way. It makes opportunity for personalized learning offering space and time to ask (why, where, how, what if) and to try. Therefore, we empower young people with skills of experimenting, and they love science back. They ask questions, make hypothesis, make problems and solve them, make mistakes, discuss about the results. Subsequently this raises the students' interest for school curriculum. This vision of science teaching is associated with inquiry-based learning. Experiment-o-mania is the unique and recognizable teaching methodology for the elementary school Drinka Pavlović, Belgrade, Serbia. Experiment-o-mania implies activities throughout the school year. They are held on extra class sessions, through science experiments, science projects or preparations for School's Days of science. Students learn to ask questions, make observations, classify data, communicate ideas, conduct experiments, analyse results and make conclusions. All science teachers participate in designing activities and experiments for students in Experiment-o-mania teaching method. But they are not alone. Teacher of fine arts, English teachers and others also take part. Students have their representatives in this team, too. This is a good way to blend knowledge among different school subject and popularize science in general. All the experiments are age appropriate and related to real life situations, local community, society and the world. We explore Fibonacci's arrays, saving energy, solar power, climate change, environmental problems, pollution, daily life situations in the country or worldwide. We introduce great scientists as Nikola Tesla, Milutin Milanković and sir Isaac Newton. We celebrate all relevant international days, weeks

Channeling of water flow and tracer transport in real fractures in a granite body at Stripa have been investigated experimentally. The experimental site was located 360 m below the ground level. Two kinds of experiments were performed. In the single hole experiments, 20 cm diameter holes were drilled about 2.5 m into the rock in the plane of the fracture. Specially designed packers were used to inject water into the fracture in 5 cm intervals all along the fracture trace in the hole. The variation of the injection flowrates along the fracture were used to determine the transmissivity variations in the fracture plane. Detailed photographs were taken from inside the hole and the visual fracture aperture was compared with the injection flowrates in the same locations. Geostatistical methods were used to evaluate the results. Five holes were measured in great detail. In addition 7 holes were drilled and scanned by simpler packer systems. A double hole experiment was performed where two parallel holes were drilled in the same fracture plane at nearly 2 m distance. Pressure pulse tests were made between the holes in both directions. Tracers were injected in 5 locations in one hole and monitored for in many locations in the other hole. The single hole experiment and the double hole experiment show that most of the fracture planes are tight but that there are open sections which form connected channels over distances of at least 2 meters. It was also found in the double hole experiment that the investigated fracture was intersected by at least one fracture between the two holes which diverted a large amount of the injected tracers to several distant locations at the tunnel wall.

Review of experiments

A study was made to examine the effects which raising the ISA from 200 x 200 GeV to 400 x 400 GeV would have on the ''canonical'' experiments. These were ''canonical'' in the sense that they span the full range of foreseeable physics and have served as topics in previous Summer Studies and Workshops which resulted in quite explicit hardware designs and experimental goals. The study results indicate that all of the ''canonical'' experiments survive. Some are actually improved, some are unaffected, and some require changes which are suggested. In general, the 90 0 experiments are relatively unaffected. The single arm small angle spectrometer, the wide aperture (FATS-WASP) spectrometer and the Coulomb interference experiment have the largest number of modifications suggested. No uniqueness to these solutions are claimed, and there may be more desirable radical approaches. It is, however, felt that the 400 x 400 GeV ISA not only permits the work on conceptual experiments from previous Summer Studies to be taken over entirely, but indicates areas of improvement in many of them. Specifics of the individual experiments are discussed

Diagnostics for pellet experiments

The target diagnostics which are being used and planned in current laser driven ICF Experiments are described. Most of these diagnostics can be easily applied to future ion-beam fusion experiments. The status of laser fusion diagnostics has been much improved in the last 5 years and further improvements can be expected and should be available when the first ICF experiments using ion beams are performed. As an example, x-ray temporal and spatial resolutions are now approximately 5 psec and 3 μm, which is approximately a factor of 4 better than the resolution reported in the first implosion experiments. As one plans ahead for ion-beam fusion experiments it should be emphasized that high yield experiments are easier to diagnose provided adequate shielding is employed. However, in the event that the first high yield experiments fail it will be necessary to have diagnostics available to determine where the problems lie. In laser fusion it is interesting to note that higher laser powers are required now for breakeven experiments than first anticipated, mainly because some aspects of the laser-interaction physics were not recognized until the experiments were carefully diagnosed. Thus as has been pointed out, it may be necessary to increase the energy of the ion-beam driver to enable us to do breakeven experiments with high confidence

The increasing use of computational simulation experiments to inform modern biological research creates new challenges to annotate, archive, share and reproduce such experiments. The recently published Minimum Information About a Simulation Experiment (MIASE) proposes a minimal set of information that should be provided to allow the reproduction of simulation experiments among users and software tools. In this article, we present the Simulation Experiment Description Markup Language (SED-ML). SED-ML encodes in a computer-readable exchange format the information required by MIASE to enable reproduction of simulation experiments. It has been developed as a community project and it is defined in a detailed technical specification and additionally provides an XML schema. The version of SED-ML described in this publication is Level 1 Version 1. It covers the description of the most frequent type of simulation experiments in the area, namely time course simulations. SED-ML documents specify which models to use in an experiment, modifications to apply on the models before using them, which simulation procedures to run on each model, what analysis results to output, and how the results should be presented. These descriptions are independent of the underlying model implementation. SED-ML is a software-independent format for encoding the description of simulation experiments; it is not specific to particular simulation tools. Here, we demonstrate that with the growing software support for SED-ML we can effectively exchange executable simulation descriptions. With SED-ML, software can exchange simulation experiment descriptions, enabling the validation and reuse of simulation experiments in different tools. Authors of papers reporting simulation experiments can make their simulation protocols available for other scientists to reproduce the results.

Kahn, J

2017-01-01

Set to begin data taking at the end of 2018, the Belle II experiment is the next-generation B-factory experiment hosted at KEK in Tsukuba, Japan. The experiment represents the cumulative effort from the collaboration of experimental and detector physics, computing, and software development. Taking everything learned from the previous Belle experiment, which ran from 1998 to 2010, Belle II aims to probe deeper than ever before into the field of heavy quark physics. By achieving an integrated luminosity of 50 ab−1 and accumulating 50 times more data than the previous experiment across its lifetime, along with a rewritten analysis framework, the Belle II experiment will push the high precision frontier of high energy physics. This paper will give an overview of the key components and development activities that make the Belle II experiment possible.

Virtual neutron scattering experiments

2016-01-01

We describe how virtual experiments can be utilized in a learning design that prepares students for hands-on experiments at large-scale facilities. We illustrate the design by showing how virtual experiments are used at the Niels Bohr Institute in a master level course on neutron scattering....... In the last week of the course, students travel to a large-scale neutron scattering facility to perform real neutron scattering experiments. Through student interviews and survey answers, we argue, that the virtual training prepares the students to engage more fruitfully with experiments by letting them focus...... on physics and data rather than the overwhelming instrumentation. We argue that this is because they can transfer their virtual experimental experience to the real-life situation. However, we also find that learning is still situated in the sense that only knowledge of particular experiments is transferred...

Wpływ prenatalnej ekspozycji na leki z grupy inhibitorów wychwytu zwrotnego serotoniny na rozwój zaburzeń ze spektrum autyzmu

Full Text Available Zaburzenia ze spektrum autyzmu są grupą zaburzeń neurorozwojowych charakteryzującą się deficytami w interakcjach społecznych, nieprawidłowościami w komunikacji i powtarzającym się, ograniczonym repertuarem zainteresowań i aktywności. Etiologia autyzmu jest niejasna, choć wyniki badań sugerują interakcję czynników genetycznych i środowiskowych, która prowadzi do nieprawidłowości w neuroprzekaźnictwie i anatomicznej budowie mózgu. Serotonina, neuroprzekaźnik obecny w ośrodkowym układzie nerwowym, obwodowo wykazujący działanie hormonu tkankowego, od dawna budzi zainteresowanie badaczy zajmujących się etiologią zaburzeń ze spektrum autyzmu. Nieprawidłowe przekaźnictwo serotoninergiczne może odgrywać zasadniczą rolę w patofizjologii zaburzeń rozwoju, co sugeruje obserwowane w wielu niezależnych badaniach zwiększone stężenie serotoniny płytkowej u średnio jednej z trzech badanych osób obciążonych zaburzeniami ze spektrum autyzmu. W związku z kluczowym znaczeniem serotoniny dla rozwoju i funkcjonowania mózgu płodu zaczęto uważniej przyglądać się prenatalnej ekspozycji na substancje zmieniające stężenie tego neurohormonu, m.in. inhibitory zwrotnego wychwytu serotoniny. Stanowią one najczęściej stosowaną grupę leków przeciwdepresyjnych na całym świecie, a badania wskazują, że  2–13% ciężarnych w krajach rozwiniętych przyjmuje leki przeciwdepresyjne. Sugerowany (lecz nadal kontrowersyjny związek między prenatalną ekspozycją na  selektywne inhibitory zwrotnego wychwytu serotoniny a wystąpieniem zaburzeń ze spektrum autyzmu może wynikać również ze wskazań do stosowania leku, takich jak depresja ciążowa. W artykule przedstawiono wyniki dotychczasowych badań nad związkiem przyjmowania przez kobiety w ciąży selektywnych inhibitorów wychwytu zwrotnego serotoniny z powstawaniem zaburzeń ze spektrum autyzmu.

Full Text Available Witamina D jest powszechnie znana ze swojej roli w gospodarce wapniowo-fosforanowej, ale wzrastająca ilość danych wskazuje na jej działania plejotropowe. Zaobserwowano pozytywną korelację między niedoborem witaminy D a występowaniem chorób autoimmunologicznych, w tym stwardnienia rozsianego, reumatoidalnego zapalenia stawów, tocznia rumieniowatego układowego itp. Receptory witaminy D są obecne w szeregu tkanek i narządów, w tym w kościach, mięśniach, narządach rozrodczych, sercu, mózgu oraz w obrębie układu odporno- ściowego. Coraz lepiej poznawane działanie immunomodulujące witaminy D obejmuje wpływ zarówno na mechanizmy odporności wrodzonej, jak i adaptacyjnej, poprzez hamowanie proliferacji i cytotoksyczności limfocytów T, promowanie różnicowania limfocytów T regulatorowych oraz modulowanie działania makrofagów i komórek dendrytycznych. Stwardnienie rozsiane (łac. sclerosis multiplex, SM jest chorobą autoimmunologiczną ośrodkowego układu nerwowego spowodowaną przez skomplikowane i w dużej mierze nieznane interakcje między predyspozycjami genetycznymi i czynnikami środowiskowymi. Badania epidemiologiczne wskazują, że ekspozycja na promieniowanie słoneczne i związany z nią poziom witaminy D są ważnymi czynnikami mogącymi wyjaśniać zróżnicowanie geograficzne częstości zachorowań na SM. Wyniki niektórych wstępnych obserwacji sugerują, że suplementacja witaminy D może zmniejszać ryzyko zachorowania na SM oraz modulować przebieg choroby i zmniejszać częstość jej nawrotów u pacjentów z rzutowo-remisyjną postacią SM. Wyniki te skłoniły do podjęcia prób włączenia witaminy D jako składnika wspomagającego terapię SM. Obserwacje te wymagają dalszego potwierdzenia i badań klinicznych.

2017-02-01

Full Text Available Transient response such as ringing in a control system can be reduced or removed by velocity feedback. It is a useful control technique that should be covered in the relevant engineering laboratory courses. We developed velocity feedback experiments using two different low cost technologies, viz., operational amplifiers and microcontrollers. These experiments can be easily integrated into laboratory courses on feedback control systems or microcontroller applications. The intent of developing these experiments was to illustrate the ringing problem and to offer effective, low cost solutions for removing such problem. In this paper the pedagogical approach for these velocity feedback experiments was described. The advantages and disadvantages of the two different implementation of velocity feedback were discussed also.

Explicating Experience: Development of a Valid Scale of Past Hazard Experience for Tornadoes.

Science.gov (United States)

Demuth, Julie L

2018-03-23

People's past experiences with a hazard theoretically influence how they approach future risks. Yet, past hazard experience has been conceptualized and measured in wide-ranging, often simplistic, ways, resulting in mixed findings about its relationship with risk perception. This study develops a scale of past hazard experiences, in the context of tornadoes, that is content and construct valid. A conceptual definition was developed, a set of items were created to measure one's most memorable and multiple tornado experiences, and the measures were evaluated through two surveys of the public who reside in tornado-prone areas. Four dimensions emerged of people's most memorable experience, reflecting their awareness of the tornado risk that day, their personalization of the risk, the intrusive impacts on them personally, and impacts experienced vicariously through others. Two dimensions emerged of people's multiple experiences, reflecting common types of communication received and negative emotional responses. These six dimensions are novel in that they capture people's experience across the timeline of a hazard as well as intangible experiences that are both direct and indirect. The six tornado experience dimensions were correlated with tornado risk perceptions measured as cognitive-affective and as perceived probability of consequences. The varied experience-risk perception results suggest that it is important to understand the nuances of these concepts and their relationships. This study provides a foundation for future work to continue explicating past hazard experience, across different risk contexts, and for understanding its effect on risk assessment and responses. © 2018 Society for Risk Analysis.

Understanding customer experience.

Meyer, Christopher; Schwager, Andre

2007-02-01

Anyone who has signed up for cell phone service, attempted to claim a rebate, or navigated a call center has probably suffered from a company's apparent indifference to what should be its first concern: the customer experiences that culminate in either satisfaction or disappointment and defection. Customer experience is the subjective response customers have to direct or indirect contact with a company. It encompasses every aspect of an offering: customer care, advertising, packaging, features, ease of use, reliability. Customer experience is shaped by customers' expectations, which largely reflect previous experiences. Few CEOs would argue against the significance of customer experience or against measuring and analyzing it. But many don't appreciate how those activities differ from CRM or just how illuminating the data can be. For instance, the majority of the companies in a recent survey believed they have been providing "superior" experiences to customers, but most customers disagreed. The authors describe a customer experience management (CEM) process that involves three kinds of monitoring: past patterns (evaluating completed transactions), present patterns (tracking current relationships), and potential patterns (conducting inquiries in the hope of unveiling future opportunities). Data are collected at or about touch points through such methods as surveys, interviews, focus groups, and online forums. Companies need to involve every function in the effort, not just a single customer-facing group. The authors go on to illustrate how a cross-functional CEM system is created. With such a system, companies can discover which customers are prospects for growth and which require immediate intervention.

Selected pertinent and uninterpreted data from the sixth anticipated transient experiment (Experiment L6-6) conducted in the Loss-of-Fluid Test (LOFT) facility are presented. Experiment L6-6 simulated a boron dilution accident by injecting demineralized water into the primary coolant system (PCS) at a rate of 0.47 L/s while the reactor was in a cold shutdown condition with the control rods withdrawn. System pressure was maintained at approximately 285 kPa throughout the experiment. The experiment was divided into two parts. In the first part, L6-6A, a recirculation flow of 4.7 L/s was maintained through the PCS and criticality was achieved 7416 +- 10 s after the initiation of the dilution flow. The second part, L6-6B, was identical to L6-6A except that a recirculation flow of 9.5 L/s was maintained and criticality occurred at 8058 +- 10 s

A system study to develop the definition of a structural flight experiment for a large precision segmented reflector on the Space Station was accomplished by the Boeing Aerospace Company for NASA's Langley Research Center. The objective of the study was to use a Large Deployable Reflector (LDR) baseline configuration as the basis for focusing an experiment definition, so that the resulting accommodation requirements and interface constraints could be used as part of the mission requirements data base for Space Station. The primary objectives of the first experiment are to construct the primary mirror support truss and to determine its structural and thermal characteristics. Addition of an optical bench, thermal shield and primary mirror segments, and alignment of the optical components, would occur on a second experiment. The structure would then be moved to the payload point system for pointing, optical control, and scientific optical measurement for a third experiment. Experiment 1 will deploy the primary support truss while it is attached to the instrument module structure. The ability to adjust the mirror attachment points and to attach several dummy primary mirror segments with a robotic system will also be demonstrated. Experiment 2 will be achieved by adding new components and equipment to experiment one. Experiment 3 will demonstrate advanced control strategies, active adjustment of the primary mirror alignment, and technologies associated with optical sensing.

Abstract The main aim of this article is to assess the financial condition and results of Polish football clubs who have the status of public benefit organizations (OPP. The analysis was conducted for clubs that were played matches in the 2013/2014 season in the men's football tournament at all levels except the highest such competitions. Ekstraklasa (no clubs having the status OPP for levels I, II, III, IV league and class district, A , B and C. All the clubs analyzed as a function of the association. The analysis shows that clubs are in a bad financial situation. Most clubs, regardless of the grade level in which the matches were played were characterized by a low value of wealth. Average debt was close to 100%. As a result, nearly one-third of the clubs showed a negative equity value. About half of the clubs observed a negative value total return on assets and return on sales. In the structure of revenues are the primary source of public funds. Other sources of income included clubs, private funds, other and income from the 1% tax on individuals.   Key words: club sports, financial analysis, income football clubs [1] e-mail artur.wyszynski@uwm.edu.pl

This report describes two experiments in which SBS would be expected to play an important role. In the first experiment, we find a clear signature of the Brillouin backscatter of a short (100 psec) pulse from a long (approx. 50 μm) gradient length gas target plasma. The second experiment used much longer (approx. 1 nsec) pulses on spherical glass shell targets. These experiments were done with both narrow ( 30A) bandwidth laser light. Using one-dimensional, spherically symmetric fluid simulations, we have attempted to model many of the laser-plasma interaction processes which combine to determine the amount of absorbed energy in the long-pulse experiments. These simulations indicate that modest laser bandwidths are successful in reducing the level of SBS at the irradiances ( 15 W/cm 2 ) used in these experiments

Memorable Experiences with Sad Music—Reasons, Reactions and Mechanisms of Three Types of Experiences

Peltola, Henna-Riikka

2016-01-01

Reactions to memorable experiences of sad music were studied by means of a survey administered to a convenience (N = 1577), representative (N = 445), and quota sample (N = 414). The survey explored the reasons, mechanisms, and emotions of such experiences. Memorable experiences linked with sad music typically occurred in relation to extremely familiar music, caused intense and pleasurable experiences, which were accompanied by physiological reactions and positive mood changes in about a third of the participants. A consistent structure of reasons and emotions for these experiences was identified through exploratory and confirmatory factor analyses across the samples. Three types of sadness experiences were established, one that was genuinely negative (Grief-Stricken Sorrow) and two that were positive (Comforting Sorrow and Sweet Sorrow). Each type of emotion exhibited certain individual differences and had distinct profiles in terms of the underlying reasons, mechanisms, and elicited reactions. The prevalence of these broad types of emotional experiences suggested that positive experiences are the most frequent, but negative experiences were not uncommon in any of the samples. The findings have implications for measuring emotions induced by music and fiction in general, and call attention to the non-pleasurable aspects of these experiences. PMID:27300268

For the development of a set of guidelines for the facilitation of citizens’ initiatives by local governments, we are experimenting with this method. It offers good opportunities for modeling interventions by testing their instrumental validity –the usefulness for the intended practical purposes. At the same time design experiments are also useful for evaluating the empirical validity of theoretical arguments and the further development of these arguments in the light of empirical evidence (by using e.g. the technique of pattern matching. We describe how we have applied this methodology in two cases and discuss our research approach. We encountered some unexpected difficulties, especially in the cooperation with professionals and citizens. These difficulties complicate the valid attribution of causal effects to the use of the new instrument. However, our preliminary conclusion is that design experiments are useful in our field of study

Online labor markets provide new opportunities for behavioral research, but conducting economic experiments online raises important methodological challenges. This particularly holds for interactive designs. In this paper, we provide a methodological discussion of the similarities and differences between interactive experiments conducted in the laboratory and online. To this end, we conduct a repeated public goods experiment with and without punishment using samples from the laboratory and the online platform Amazon Mechanical Turk. We chose to replicate this experiment because it is long and logistically complex. It therefore provides a good case study for discussing the methodological and practical challenges of online interactive experimentation. We find that basic behavioral patterns of cooperation and punishment in the laboratory are replicable online. The most important challenge of online interactive experiments is participant dropout. We discuss measures for reducing dropout and show that, for our case study, dropouts are exogenous to the experiment. We conclude that data quality for interactive experiments via the Internet is adequate and reliable, making online interactive experimentation a potentially valuable complement to laboratory studies.

A study was performed to develop the definition of a structural flight experiment for a large precision segmented reflector that would utilize the Space Station. The objective of the study was to use the Large Deployable Reflector (LDR) baseline configuration for focusing on experiment definition activity which would identify the Space Station accommodation requirements and interface constraints. Results of the study defined three Space Station based experiments to demonstrate the technologies needed for an LDR type structure. The basic experiment configurations are the same as the JPL baseline except that the primary mirror truss is 10 meters in diameter instead of 20. The primary objectives of the first experiment are to construct the primary mirror support truss and to determine its structural and thermal characteristics. Addition of the optical bench, thermal shield and primary mirror segments and alignment of the optical components occur on the second experiment. The structure will then be moved to the payload pointing system for pointing, optical control and scientific optical measurement for the third experiment.

Vukadinović Maja

2012-01-01

Full Text Available In this study the aesthetic experience of dance performances is investigated. The study includes construction of an instrument for measuring the aesthetic experience of dance performances and an investigation of the structure of both dancers’ and spectators’ aesthetic experience. The experiments are carried out during eight different performances of various dance forms, including classical ballet, contemporary dance, flamenco and folklore. Three factors of aesthetic experience of dance performances are identified: Dynamism, Exceptionality and Affective Evaluation. The results show that dancers’ aesthetic experience has a somewhat different factorial structure from that of the spectators’. Unlike spectators’ aesthetic experience, dancers’ aesthetic experience singles out the Excitement factor. The results are discussed within the context of dancers’ proprioception and spectators’ exteroception since these findings confirm the idea of a significant role of proprioception in dancers’ aesthetic experience.

Acute adverse psychological reactions to classic hallucinogens (“bad trips”, or “challenging experiences”), while usually benign with proper screening, preparation, and support in controlled settings, remain a safety concern in uncontrolled settings (such as illicit use contexts). Anecdotal and case reports suggest potential adverse acute symptoms including affective (panic, depressed mood), cognitive (confusion, feelings of losing sanity), and somatic (nausea, heart palpitation) symptoms. Responses to items from several hallucinogen-sensitive questionnaires (Hallucinogen Rating Scale, the States of Consciousness Questionnaire, and the 5-Dimensional Altered States of Consciousness questionnaire) in an internet survey of challenging experiences with the classic hallucinogen psilocybin were used to construct and validate a Challenging Experience Questionnaire (CEQ). The stand-alone CEQ was then validated in a separate sample. Seven CEQ factors (grief, fear, death, insanity, isolation, physical distress, and paranoia) provide a phenomenological profile of challenging aspects of experiences with psilocybin. Factor scores were associated with the difficulty, meaningfulness, spiritual significance, and change in well-being attributed to the challenging experiences. The factor structure did not differ based on gender or prior struggle with anxiety or depression. The CEQ provides a basis for future investigation of predictors and outcomes of challenging experiences with psilocybin, and should be explored as a measure of challenging experiences with the broad class of classic hallucinogens.

W artykule przedstawiono wyniki przeprowadzonych analiz mikroskopowych, analizy obrazów zdjęć skaningowych oraz procedury wykorzystania otrzymanych informacji do identyfikacji typów rud (zastosowanie sieci neuronowych do rozpoznawania składów litologicznych). W badaniach wykorzystano rudę miedzi, pochodzącą z jednego z zakładów górniczych KGHM Polska Miedź S.A. Pobrane próbki rudy reprezentowały każdy z trzech typów litologicznych występujących w krajowych złożach: węglanową, łupkową oraz piaskowcową. Przeprowadzono ilościową analizę mineralogiczno-petrograficzną przy pomocy mikroskopu optycznego w świetle odbitym, a wyniki przedstawiono w tabelach 1 i 2. Wyniki te określają ilościowo stopień uwolnienia i zrosty dla jednego rodzaju minerału. Pokazano także przykładowe zdjęcia mikroskopowe zgładów poszczególnych typów litologicznych rud oraz próbek proszkowych tych typów (rys. 1 i 2). W kolejnym etapie badań wykorzystano skaningowy mikroskop elektronowy. Zdjęcia morfologii próbek uzyskane z mikroskopu elektronowego (obrazy SEM) były przedmiotem komputerowej analizy obrazu, umożliwiającej mikrostrukturalną klasyfikację ilościową typów rud. Analizowano wszystkie próbki poszczególnych typów litologicznych rudy miedzi: węglanowej, łupkowej i piaskowcowej oraz mieszanki tych typów w trzech klasach ziarnowych: 0÷45 μm, 45÷71 μm i 71÷100 μm.

The LOFT Experiments L5-1 and L8-2 simulated intermediate break loss-of-coolant accidents with core uncovery. This paper compares the predictions with the measured data for these experiments. The RELAP5 code was used to perform best estimate double-blind and single-blind predictions. The double-blind calculations are performed prior to the experiment and use specified nominal initial and boundary conditions. The single-blind calculations are performed after the experiment and use measured initial and boundary conditions while maintaining all other parameters constant, including the code version. Comparisons of calculated results with experimental results are discussed; the possible causes of discrepancies are explored and explained. RELAP5 calculated system pressure, mass inventory, and fuel cladding temperature agree reasonably well with the experiment results, and only slight changes are noted between the double-blind and single-blind predictions

The Space Experiment Module (SEM) Program is an education initiative sponsored by the National Aeronautics and Space Administration (NASA) Shuttle Small Payloads Project. The program provides nationwide educational access to space for Kindergarten through University level students. The SEM program focuses on the science of zero-gravity and microgravity. Within the program, NASA provides small containers or "modules" for students to fly experiments on the Space Shuttle. The experiments are created, designed, built, and implemented by students with teacher and/or mentor guidance. Student experiment modules are flown in a "carrier" which resides in the cargo bay of the Space Shuttle. The carrier supplies power to, and the means to control and collect data from each experiment.

Radiochemical solar neutrino experiments

Rich, R.; Spiro, M.

1993-01-01

This review covers the three presently running radiochemical solar neutrino experiments, namely the Chlorine, SAGE, and GALLEX experiments. The focus of the review is on a discussion of statistical consistency checks of the available data. The chlorine radiochemical experiment is conceptually simple and shows no strong indication of any statistical anomalies. It still forms the basis of the solar neutrino problem. Each of the two gallium experiments show internal statistical consistency. SAGE's recent preliminary results are consistent with the published GALLEX results. If this convergence is confirmed by a more definitive analysis, this would suggest that the combined result of the two gallium experiments, SAGE and GALLEX, be used for comparisons with theoretical expectations. 5 refs., 15 figs

Inverse Cerenkov experiment

Kimura, W.D.

1993-01-01

The final report describes work performed to investigate inverse Cherenkov acceleration (ICA) as a promising method for laser particle acceleration. In particular, an improved configuration of ICA is being tested in a experiment presently underway on the Accelerator Test Facility (ATF). In the experiment, the high peak power (∼ 10 GW) linearly polarized ATF CO 2 laser beam is converted to a radially polarized beam. This is beam is focused with an axicon at the Cherenkov angle onto the ATF 50-MeV e-beam inside a hydrogen gas cell, where the gas acts as the phase matching medium of the interaction. An energy gain of ∼12 MeV is predicted assuming a delivered laser peak power of 5 GW. The experiment is divided into two phases. The Phase I experiments, which were completed in the spring of 1992, were conducted before the ATF e-beam was available and involved several successful tests of the optical systems. Phase II experiments are with the e-beam and laser beam, and are still in progress. The ATF demonstrated delivery of the e-beam to the experiment in Dec. 1992. A preliminary ''debugging'' run with the e-beam and laser beam occurred in May 1993. This revealed the need for some experimental modifications, which have been implemented. The second run is tentatively scheduled for October or November 1993. In parallel to the experimental efforts has been ongoing theoretical work to support the experiment and investigate improvement and/or offshoots. One exciting offshoot has been theoretical work showing that free-space laser acceleration of electrons is possible using a radially-polarized, axicon-focused laser beam, but without any phase-matching gas. The Monte Carlo code used to model the ICA process has been upgraded and expanded to handle different types of laser beam input profiles

Do entheogen-induced mystical experiences boost the immune system? Psychedelics, peak experiences, and wellness.

Science.gov (United States)

Roberts, T B

1999-01-01

Daily events that boost the immune system (as indicated by levels of salivary immunoglobulin A), some instances of spontaneous remission, and mystical experiences seem to share a similar cluster of thoughts, feelings, moods, perceptions, and behaviors. Entheogens--psychedelic drugs used in a religious context--can also produce mystical experiences (peak experiences, states of unitive consciousness, intense primary religious experiences) with the same cluster of effects. When this happens, is it also possible that such entheogen-induced mystical experiences strengthen the immune system? Might spontaneous remissions occur more frequently under such conditions? This article advances the so called "Emxis hypothesis"--that entheogen-induced mystical experiences influence the immune system.

2008-01-01

In Experiment, Right or Wrong, Allan Franklin continues his investigation of the history and philosophy of experiment presented in his previous book, The Neglect of Experiment. In this new study, Franklin considers the fallibility and corrigibility of experimental results and presents detailed histories of two such episodes: 1) the experiment and the development of the theory of weak interactions from Fermi's theory in 1934 to the V-A theory of 1957 and 2) atomic parity violation experiments and the Weinberg-Salam unified theory of electroweak interactions of the 1970s and 1980s. In these episodes Franklin demonstrates not only that experimental results can be wrong, but also that theoretical calculations and the comparison between experiment and theory can also be incorrect. In the second episode, Franklin contrasts his view of an "evidence model" of science in which questions of theory choice, confirmation, and refutation are decided on the basis of reliable experimental evidence, with that proposed by the ...

What Public Experience May Be – On Publicity, Communication and the Expression of Lived Experiences

Directory of Open Access Journals (Sweden)

Samuel Mateus

2016-09-01

Full Text Available The idea of public experience is often invoked in different social and academic contexts. However, it seldom deserved a reflection that specifically sought to deepen its meaning from the point of view of social life. In this article we contribute to the understanding of the uniqueness of the public form of experience. We believe that one of the best ways through which we can observe the public experience is by the objectification, performance and dramatization of the culture, i.e., the “expression of lived experiences”. There is, in publicity, the possibility of simultaneous allocation of individual and collective experiences, and it is in this sense that we can see how culture influences the shaping of experience itself. Public experience is characterized by the weaving and intertwining of singular experiences that are pluralized and plural lived experiences that are singularized, in a process where individual and society interpenetrate. The relationship between experience and publicity arises from this symbolic communion contained in the systems of thought and action of societies. The decisive role of the principle of publicity to experience consists, according with the hypothesis we wish to put forward, in making available and communicating the social world of symbolic (cultural activity. Public experience is, then, envisaged as the experience of a common world where both singular and plural definitions of the individual (taken as society converge through lived experiences and, particularly, through their expression, which can take different symbolic forms.

In fusion reactors, charge exchange neutral atoms of tritium coming from the plasma will be implanted into the first wall and other interior structures. EG and G Idaho is conducting two experiments to determine the magnitude of permeation into the coolant streams and the retention of tritium in those structures. One experiment uses an ion gun to implant deuterium. The ion gun will permit measurements to be made for a variety of implantation energies and fluxes. The second experiment utilizes a fission reactor to generate a tritium implantation flux by the 3 He(n,p) 3 H reaction. This experiment will simulate the fusion reactor radiation environment. We also plan to verify a supporting analytical code development program, in progress, by these experiments

Experience Supporting the Integration of LHC Experiments Software Framework with the LCG Middleware

CERN Document Server

Santinelli, Roberto

2006-01-01

The LHC experiments are currently preparing for data acquisition in 2007 and because of the large amount of required computing and storage resources, they decided to embrace the grid paradigm. The LHC Computing Project (LCG) provides and operates a computing infrastructure suitable for data handling, Monte Carlo production and analysis. While LCG offers a set of high level services, intended to be generic enough to accommodate the needs of different Virtual Organizations, the LHC experiments software framework and applications are very specific and focused on the computing and data models. The LCG Experiment Integration Support team works in close contact with the experiments, the middleware developers and the LCG certification and operations teams to integrate the underlying grid middleware with the experiment specific components. The strategical position between the experiments and the middleware suppliers allows EIS team to play a key role at communications level between the customers and the service provi...

The criteria for the selection of the experimental areas and individual experiments were that the experiment or area must make a meaningful contribution to the field of material science and that the space environment was either an absolute requirement for the successful execution of the experiment or that the experiment can be more economically or more conveniently performed in space. A number of experimental areas and individual experiments were recommended for further consideration as space experiments. Areas not considered to be fruitful and others needing additional analysis in order to determine their suitability for conduct in space are also listed. Recommendations were made concerning the manner in which these materials science experiments are carried out and the related studies that should be pursued.

Experiments on ferrimagnetism

International Nuclear Information System (INIS)

Kraftmakher, Yaakov

2013-01-01

Ferrimagnetism undoubtedly deserves a proper place in the undergraduate laboratory on electricity and magnetism. Four student experiments on ferrimagnetism are considered: (i) the hysteresis loops and permeability of a ‘soft’ ferrite; (ii) the differential permeability versus a dc bias; (iii) the frequency dependence of the complex permeability and (iv) the electromagnetic interference suppression by ferrite chokes and beads. Two ferrite cores taken off a low-frequency choke and a power cord are used. The measurements are simple and straightforward and show the important properties of ferrites and their applications. The values of the permeability of the ferrite core determined in experiments (i)–(iii) are in reasonable agreement. The frequency dependence of the complex permeability of the ferrites is similar to that given by the manufacturers. The capability of absorbing electromagnetic waves in a definite frequency range shown in experiment (iv) demonstrates one of the principles of Stealth technology. The equipment necessary for the experiments can be found in many student laboratories. (paper)

[The AMY experiment

International Nuclear Information System (INIS)

1989-01-01

The AMY experiment is one of three major experiments at TRISTAN which is studying the states the matter produced in electron positron annihilations in the center of mass energy range of 50--65GeV. It provides information between the lower energy facilities such as PEP and PETRA and the new facilities SLC and LEP which are designed to operate in the region of the Z 0 mass near 90GeV. In the region of the AMY experiment, interaction cross sections are near their minimum of about 100pb, making it difficult to acquire large data samples during typical running cycles. This last year has seen an accumulation of about 10---12pb -1 of integrated luminosity in the energy range from 58 to 61.7GeV. Despite this limited data sample, the AMY experiment has been extremely active in attempting to extract the minimum amount of information from the data. Some of the most significant results are discussed in this paper. 9 refs

Olkiluoto 3 Experience

International Nuclear Information System (INIS)

Tiippana, Petteri

2011-01-01

This paper discusses the experience from the Olkiluoto 3 nuclear power plant project from regulator's point of view. There are certain factors that have affected greatly the project progress. First, Olkiluoto 3 nuclear power plant is the first European Pressurised Reactor (EPR) being constructed. Secondly, construction of the unit started after a fairly long break in nuclear power plant construction in Europe, which had resulted in loss of experienced and qualified engineering and manufacturing resources. These factors have to be kept in mind when evaluating the experience from Olkiluoto 3. Experience discussed in this paper have to do with the licensing and regulatory oversight process, completion of the design prior to construction, experience and know-how of the participating organisations, quality management in a nuclear construction project, advanced manufacturing and construction technologies, turnkey contract with regard to licensee's responsibility, safety culture aspects in a nuclear construction project, and the role and importance of regulator's oversight.

The G0 experiment measures the parity-violating asymmetries in elastic electron-proton and quasi-elastic electron-deuteron scattering over the momentum transfers 0.12 ≤ Q2 ≤ 1.0 GeV2. These asymmetries are sensitive to the strange-quark contribution to the charge and magnetization distributions of the proton. The experiment is conducted at Jefferson Laboratory using a toroidal spectrometer designed to detect forward scattered recoil protons and backward scattered elastic and quasi-elastic electrons. The forward angle experiment was completed in 2004, and the backward angle phase of the experiment is currently taking place

Welcome to the experience economy.

Science.gov (United States)

Pine, B J; Gilmore, J H

1998-01-01

First there was agriculture, then manufactured goods, and eventually services. Each change represented a step up in economic value--a way for producers to distinguish their products from increasingly undifferentiated competitive offerings. Now, as services are in their turn becoming commoditized, companies are looking for the next higher value in an economic offering. Leading-edge companies are finding that it lies in staging experiences. To reach this higher level of competition, companies will have to learn how to design, sell, and deliver experiences that customers will readily pay for. An experience occurs when a company uses services as the stage--and goods as props--for engaging individuals in a way that creates a memorable event. And while experiences have always been at the heart of the entertainment business, any company stages an experience when it engages customers in a personal, memorable way. The lessons of pioneering experience providers, including the Walt Disney Company, can help companies learn how to compete in the experience economy. The authors offer five design principles that drive the creation of memorable experiences. First, create a consistent theme, one that resonates throughout the entire experience. Second, layer the theme with positive cues--for example, easy-to-follow signs. Third, eliminate negative cues, those visual or aural messages that distract or contradict the theme. Fourth, offer memorabilia that commemorate the experience for the user. Finally, engage all five senses--through sights, sounds, and so on--to heighten the experience and thus make it more memorable.

Nitrogen-detected CAN and CON experiments as alternative experiments for main chain NMR resonance assignments

International Nuclear Information System (INIS)

Takeuchi, Koh; Heffron, Gregory; Sun, Zhen-Yu J.; Frueh, Dominique P.; Wagner, Gerhard

2010-01-01

Heteronuclear direct-detection experiments, which utilize the slower relaxation properties of low γ nuclei, such as 13 C have recently been proposed for sequence-specific assignment and structural analyses of large, unstructured, and/or paramagnetic proteins. Here we present two novel 15 N direct-detection experiments. The CAN experiment sequentially connects amide 15 N resonances using 13 C α chemical shift matching, and the CON experiment connects the preceding 13 C' nuclei. When starting from the same carbon polarization, the intensities of nitrogen signals detected in the CAN or CON experiments would be expected four times lower than those of carbon resonances observed in the corresponding 13 C-detecting experiment, NCA-DIPAP or NCO-IPAP (Bermel et al. 2006b; Takeuchi et al. 2008). However, the disadvantage due to the lower γ is counteracted by the slower 15 N transverse relaxation during detection, the possibility for more efficient decoupling in both dimensions, and relaxation optimized properties of the pulse sequences. As a result, the median S/N in the 15 N observe CAN experiment is 16% higher than in the 13 C observe NCA-DIPAP experiment. In addition, significantly higher sensitivity was observed for those residues that are hard to detect in the NCA-DIPAP experiment, such as Gly, Ser and residues with high-field C α resonances. Both CAN and CON experiments are able to detect Pro resonances that would not be observed in conventional proton-detected experiments. In addition, those experiments are free from problems of incomplete deuterium-to-proton back exchange in amide positions of perdeuterated proteins expressed in D 2 O. Thus, these features and the superior resolution of 15 N-detected experiments provide an attractive alternative for main chain assignments. The experiments are demonstrated with the small model protein GB1 at conditions simulating a 150 kDa protein, and the 52 kDa glutathione S-transferase dimer, GST.

This paper presents an overview of the Cryogenic Test Bed (CTB) experiments including experiment results, integration techniques used, and lessons learned during integration, test and flight phases of the Cryogenic Heat Pipe Flight Experiment (STS-53) and the Cryogenic Two Phase Flight Experiment (OAST-2, STS-62). We will also discuss the Cryogenic Flexible Diode Heat Pipe (CRYOFD) experiment which will fly in the 1996/97 time frame and the fourth flight of the CTB which will fly in the 1997/98 time frame. The two missions tested two oxygen axially grooved heat pipes, a nitrogen fibrous wick heat pipe and a 2-methylpentane phase change material thermal storage unit. Techniques were found for solving problems with vibration from the cryo-collers transmitted through the compressors and the cold heads, and mounting the heat pipe without introducing parasitic heat leaks. A thermally conductive interface material was selected that would meet the requirements and perform over the temperature range of 55 to 300 K. Problems are discussed with the bi-metallic thermostats used for heater circuit protection and the S-Glass suspension straps originally used to secure the BETSU PCM in the CRYOTP mission. Flight results will be compared to 1-g test results and differences will be discussed.

Chen, T.H.; Modro, S.M.

1983-01-01

The LOFT Experiments L5-1 and L8-2 simulated intermediate break loss-of-coolant accidents with core uncovery. This paper compares the predictions with the measured data for these experiments. The RELAP5 code was used to perform best estimate double-blind and single-blind predictions. The double-blind calculations are performed prior to the experiment and use specified nominal initial and boundary conditions. The single-blind calculations are performed after the experiment and use measured initial and boundary conditions while maintaining all other parameters constant, including the code version. Comparisons of calculated results with experimental results are discussed; the possible causes of discrepancies are explored and explained. RELAP5 calculated system pressure, mass inventory, and fuel cladding temperature agree reasonably well with the experiment results, and only slight changes are noted between the double-blind and single-blind predictions

In this paper we present the Experiment Dashboard monitoring system, which is currently in use by four Large Hadron Collider (LHC) experiments. The goal of the Experiment Dashboard is to monitor the activities of the LHC experiments on the distributed infrastructure, providing monitoring data from the virtual organization (VO) and user perspectives. The LHC experiments are using various Grid infrastructures (LCG/EGEE, OSG, NDGF) with correspondingly various middleware flavors and job submission methods. Providing a uniform and complete view of various activities like job processing, data movement and publishing, access to distributed databases regardless of the underlying Grid flavor is the challenging task. In this paper we will describe the Experiment Dashboard concept, its framework and main monitoring applications

Sampling Participants' Experience in Laboratory Experiments: Complementary challenges for more complete data collection

Directory of Open Access Journals (Sweden)

Alan eMcAuliffe

2016-05-01

Full Text Available Speelman and McGann's (2013 examination of the uncritical way in which the mean is often used in psychological research raises questions both about the average's reliability and its validity. In the present paper, we argue that interrogating the validity of the mean involves, amongst other things, a better understanding of the person's experiences, the meaning of their actions, at the time that the behaviour of interest is carried out. Recently emerging approaches within Psychology and Cognitive Science have argued strongly that experience should play a more central role in our examination of behavioural data, but the relationship between experience and behaviour remains very poorly understood. We outline some of the history of the science on this fraught relationship, as well as arguing that contemporary methods for studying experience fall into one of two categories. Wide approaches tend to incorporate naturalistic behaviour settings, but sacrifice accuracy and reliability in behavioural measurement. Narrow approaches maintain controlled measurement of behaviour, but involve too specific a sampling of experience, which obscures crucial temporal characteristics. We therefore argue for a novel, mid-range sampling technique, that extends Hurlburt's Descriptive Experience Sampling, and adapts it for the controlled setting of the laboratory. This Controlled Descriptive Experience Sampling may be an appropriate tool to help calibrate both the mean and the meaning of an experimental situation with one another.

The OLYMPUS experiment was designed to measure the ratio between the positron-proton and electron-proton elastic scattering cross sections, with the goal of determining the contribution of two-photon exchange to the elastic cross section. Two-photon exchange might resolve the discrepancy between measurements of the proton form factor ratio, {mu}{sub p}G{sup p}{sub E}/G{sup p}{sub M}, made using polarization techniques and those made in unpolarized experiments. OLYMPUS operated on the DORIS storage ring at DESY, alternating between 2.01 GeV electron and positron beams incident on an internal hydrogen gas target. The experiment used a toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight detectors to measure rates for elastic scattering over the polar angular range of approximately 25 -75 . Symmetric Moeller/Bhabha calorimeters at 1.29 and telescopes of GEM and MWPC detectors at 12 served as luminosity monitors. A total luminosity of approximately 4.5 fb{sup -1} was collected over two running periods in 2012. This paper provides details on the accelerator, target, detectors, and operation of the experiment.

In the Los Alamos Magnetized Gun Experiment we are attempting to produce a compact torus in a manner similar to an earlier experiment of Alfven. In our experiment a solenoidal coil is placed inside the inner electrode of a coaxial plasma gun. This coil produces an axial magnetic field inside the inner electrode which diverges and becomes a largely radial field in front of the gun muzzle. The idea is that when the gun is fired, the plasma escaping from the gun stretches these radial fields along the axial direction away from the gun, and these field lines can reconnect behind the plasma forming the poloidal field of the compact torus. The magnetic field generated by the gun current becomes the toroidal field and the major axis of the compact torus will be the same as the axis of the coaxial gun. Recent interest in this possible method of compact torus generation was stimulated by C. Hartman, and the approach is also being pursued in the field-reversed plasma gun experiment at LLL

Molybdenum solar neutrino experiment

Wolfsberg, K.; Cowan, G.A.; Bryant, E.A.

1984-01-01

The goal of the molybdenum solar neutrino experiment is to deduce the 8 B solar neutrino flux, averaged over the past several million years, from the concentration of 98 Tc in a deeply buried molybdenum deposit. The experiment is important to an understanding of stellar processes because it will shed light on the reason for the discrepancy between theory and observation of the chlorine solar neutrino experiment. Possible reasons for the discrepancy may lie in the properties of neutrinos (neutrino oscillations or massive neutrinos) or in deficiencies of the standard solar model. The chlorine experiment only measures the 8 B neutrino flux in current times and does not address possible temporal variations in the interior of the sun, which are also not considered in the standard model. In the molybdenum experiment, we plan to measure 98 Tc (4.2 Myr), also produced by 8 B neutrinos, and possibly 97 Tc (2.6 Myr), produced by lower energy neutrinos

Undergraduate reactor control experiment

1992-01-01

A sequence of reactor and related experiments has been a central element of a senior-level laboratory course at Pennsylvania State University (Penn State) for more than 20 yr. A new experiment has been developed where the students program and operate a computer controller that manipulates the speed of a secondary control rod to regulate TRIGA reactor power. Elementary feedback control theory is introduced to explain the experiment, which emphasizes the nonlinear aspect of reactor control where power level changes are equivalent to a change in control loop gain. Digital control of nuclear reactors has become more visible at Penn State with the replacement of the original analog-based TRIGA reactor control console with a modern computer-based digital control console. Several TRIGA reactor dynamics experiments, which comprise half of the three-credit laboratory course, lead to the control experiment finale: (a) digital simulation, (b) control rod calibration, (c) reactor pulsing, (d) reactivity oscillator, and (e) reactor noise

Cryogenics for LHC experiments

Cryogenic systems will be used by LHC experiments to maximize their performance. Institutes around the world are collaborating with CERN in the construction of these very low temperature systems. The cryogenic test facility in hall 180 for ATLAS magnets. High Energy Physics experiments have frequently adopted cryogenic versions of their apparatus to achieve optimal performance, and those for the LHC will be no exception. The two largest experiments for CERN's new flagship accelerator, ATLAS and CMS, will both use large superconducting magnets operated at 4.5 Kelvin - almost 270 degrees below the freezing point of water. ATLAS also includes calorimeters filled with liquid argon at 87 Kelvin. For the magnets, the choice of a cryogenic version was dictated by a combination economy and transparency to emerging particles. For the calorimeters, liquid argon was selected as the fluid best suited to the experiment's physics requirements. High Energy Physics experiments are the result of worldwide collaborations and...

Physical experience enhances science learning.

Kontra, Carly; Lyons, Daniel J; Fischer, Susan M; Beilock, Sian L

2015-06-01

Three laboratory experiments involving students' behavior and brain imaging and one randomized field experiment in a college physics class explored the importance of physical experience in science learning. We reasoned that students' understanding of science concepts such as torque and angular momentum is aided by activation of sensorimotor brain systems that add kinetic detail and meaning to students' thinking. We tested whether physical experience with angular momentum increases involvement of sensorimotor brain systems during students' subsequent reasoning and whether this involvement aids their understanding. The physical experience, a brief exposure to forces associated with angular momentum, significantly improved quiz scores. Moreover, improved performance was explained by activation of sensorimotor brain regions when students later reasoned about angular momentum. This finding specifies a mechanism underlying the value of physical experience in science education and leads the way for classroom practices in which experience with the physical world is an integral part of learning. © The Author(s) 2015.

Selected pertinent and uninterpreted data from the fourth anticipated transient with multiple failures experiment (Experiment L9-4) conducted on September 24, 1982, in the Loss-of-Fluid Test (LOFT) facility are presented. The LOFT facility is a 50-MW(t) pressurized water reactor (PWR) system with instruments that measure and provide data on the system's thermal-hydraulic and nuclear conditions. The operation of the LOFT system is typical of large [approx. 1000 MW(e)], commercial PWR operations. Experiment L9-4 simulated a loss-of-offsite-power anticipated transient without reactor scram. The loss-of-offsite-power accident led to an increase in the primary coolant system temperature and pressure. The experiment safety relief valve opened and was able to limit and control the pressure transient. In addition, subsequent heat generation was dissipated by the auxiliary feedwater flow in the secondary coolant system until the reactor was scrammed at experiment termination

I den sidste uge af kurset, rejser studerende til et storskala neutronspredningsfacilitet for at udføre neutronspredningseksperimenter. Vi bruger studerendes udsagn om deres oplevelser til at argumentere for, at arbejdet med virtuelle experimenter forbereder de studerende til at engagere sig mere frugtbart med eksperimenter ved at lade dem fokusere på fysikken og relevante data i stedet for instrumenternes funktion. Vi hævder, at det er, fordi de kan overføre deres erfaringer med virtuelle eksperimenter til rigtige eksperimenter. Vi finder dog, at læring stadig er situeret i den forstand, at kun kendskab til bestemte eksperimenter overføres. Vi afslutter med at diskutere de muligheder, som virtuelle eksperimenter giver. English We describe how virtual experiments can be utilized in a learning design that prepares students for hands-on experiments at large-scale facilities. We illustrate the design by showing how virtual experiments are used at the Niels Bohr Institute in a master level course on neutron scattering. In the last week of the course, students travel to a large-scale neutron scattering facility to perform real neutron scattering experiments. Through student interviews and survey answers, we argue, that the virtual training prepares the students to engage more fruitfully with experiments by letting them focus on physics and data rather than the overwhelming instrumentation. We argue that this is because they can transfer their virtual experimental experience to the real-life situation. However, we also find that learning is still situated in the sense that only knowledge of particular experiments is transferred. We proceed to

Transcendental experiences during meditation practice.

Science.gov (United States)

Travis, Frederick

2014-01-01

This article explores transcendental experiences during meditation practice and the integration of transcendental experiences and the unfolding of higher states of consciousness with waking, dreaming, and sleeping. The subject/object relationship during transcendental experiences is characterized by the absence of time, space, and body sense--the framework that gives meaning to waking experiences. Physiologically, transcendental experiences during Transcendental Meditation practice are marked by slow inhalation, along with autonomic orientation at the onset of breath changes and heightened α1 (8-10 Hz) frontal coherence. The integration of transcendental experiences with waking, dreaming, and sleeping is also marked by distinct subjective and objective markers. This integrated state, called Cosmic Consciousness in the Vedic tradition, is subjectively marked by inner self-awareness coexisting with waking, sleeping, and dreaming. Physiologically, Cosmic Consciousness is marked by the coexistence of α1 electroencephalography (EEG) with delta EEG during deep sleep, and higher brain integration, greater emotional stability, and decreased anxiety during challenging tasks. Transcendental experiences may be the engine that fosters higher human development. © 2013 New York Academy of Sciences.

The OLYMPUS experiment was designed to measure the ratio between the positron–proton and electron–proton elastic scattering cross-sections, with the goal of determining the contribution of two-photon exchange to the elastic cross-section. Two-photon exchange might resolve the discrepancy between measurements of the proton form factor ratio, μ{sub p}G{sub E}{sup p}/G{sub M}{sup p}, made using polarization techniques and those made in unpolarized experiments. OLYMPUS operated on the DORIS storage ring at DESY, alternating between 2.01 GeV electron and positron beams incident on an internal hydrogen gas target. The experiment used a toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight detectors to measure rates for elastic scattering over the polar angular range of approximately 25°–75°. Symmetric Møller/Bhabha calorimeters at 1.29° and telescopes of GEM and MWPC detectors at 12° served as luminosity monitors. A total luminosity of approximately 4.5 fb{sup −1} was collected over two running periods in 2012. This paper provides details on the accelerator, target, detectors, and operation of the experiment.

Recent (first or/and the best) results from the neutrino experiments are reviewed and their implications for the theory are discussed. The sense of the experiments is the searching for neutrino masses, mixing and interactions beyond the standard model. Present laboratory experiments give upper bounds on the masses and the mixing which are at the level of predictions of the ''electroweak see-saw''. Positive indications of nonzero lepton mixing follow from studies of the solar and atmospheric neutrinos. (author). 95 refs, 11 figs

Tourist product in experience economy

OpenAIRE

Stasiak Andrzej

2014-01-01

The turn of the 20th and 21st c. was marked by the development of experience economy, in which the basic commodities are not specific products, but the customers’ emotions, impressions and experiences. Tourism has always been a particular “holiday experience industry”. In recent years, however, the importance of the conscious creation of emotional tourism products has become even greater; we may observe continuous efforts to multiply and intensify tourism experience. The key activities to ach...

experience in school

Full Text Available An experiment investigated the effect of a make-believe fantasy mode of problem presentation on reasoning about valid conditional syllogisms in three groups of 5-year-old children: a school children from middle-class families in England; b school children from middle-class families in Brazil; and, c children from low SES families in Brazil who had never gone to school. Previous investigations had reported that the use of a fantasy context elicited significantly more logically appropriate responses from school children than did other contexts, and that children with school experiences made significantly more logically appropriate responses than did children without school experience. The present investigation extended these findings to show that the beneficial effects of a fantasy context extended to lower-class illiterate children who never had been exposed to schooling

"Experience Isn't Everything": How Emotion Affects the Relationship Between Experience and Cue Utilization.

This research examined whether negative and positive arousal emotions modify the relationship between experience level and cue utilization among anesthetists. The capacity of a practitioner to form precise associations between clusters of features (e.g., symptoms) and events (e.g., diagnosis) and then act on them is known as cue utilization. A common assumption is that practice experience allows opportunities for cue acquisition and cue utilization. However, this relationship is often not borne out in research findings. This study investigates the role of emotional state in this relationship. An online tool (EXPERTise 2.0) was used to assess practitioner cue utilization for tasks relevant to anesthesia. The experience of positive and negative arousal emotions in the previous three days was measured, and emotion clusters were generated. Experience was measured as the composite of practice years and hours of practice experience. The moderating role of emotion on the relationship between experience and cue utilization was examined. Data on 125 anesthetists (36% female) were included in the analysis. The predicted interaction between arousal emotions and the experience level emerged. In particular, post hoc analyses revealed that anxiety-related emotions facilitated the likelihood of high cue utilization in less experienced practitioners. The findings suggest a role for emotions in cue use and suggest a functional role for normal range anxiety emotions in a simulated work-relevant task. This research illustrates the importance of understanding the potentially functional effects common negative arousal emotions may have on clinical performance, particularly for those with less experience.

Results of the Los Alamos theta-pinch program in three areas of investigation are summarized: 1) In the Staged Theta Pinch, results are reported on the effects of magnetic field amplitude and time history of plasma formation. 2) In the Implosion Heating Experiment, density, internal-magnetic field and neutron measurements yield a consistent picture of the implosion which agrees with kinetic computations and with a simple dynamic model of the ions and magnetic piston. 3) In the Scyllac Feedback-Sector Experiment, the l=1, 0 equilibrium plasma parameters have been adjusted to accommodate the feedback stabilization system. With a uniform toroidal discharge tube the m=1 instability is feedback-stabilized in the vertical direction, and confinement in the toroidal direction is extended by feedback control. Results with a helical discharge tube are also reported. (author)

Aura, Self, and Aesthetic Experience

Directory of Open Access Journals (Sweden)

Marshall Battani

2011-01-01

Full Text Available Aesthetic experiences are generated in encounters with cultural objects and such experiences are marked by the free play of cognitive and numinous experience unstructured by concepts. Kant’s famous three types of pleasure, made infamous in social theory by Pierre Bourdieu, are examined in relation to the critical theoretical concept of aura, the social psychology of “flow,” and cognitive explanations of perception to explain experience in aesthetic fields. Theories of aesthetic experience developed at the crossroad of critical social thought and cognitive science hold promise for a social analysis able to avoid the usual sociological pitfalls of either ignoring aesthetics or reducing it to structurally determined differences of taste.

Operational experience with Dragon reactor experiment of relevance to commercial reactors

International Nuclear Information System (INIS)

Capp, P.D.; Simon, R.A.

1976-01-01

An important part of the experience gained during the first ten years of successful power operation of the Dragon Reactor is relevant to the design and operation of future High Temperature Reactors (HTRs). The aspects presented in this paper have been chosen as being particularly applicable to larger HTR systems. Core performance under a variety of conditions is surveyed with particular emphasis on a technique developed for the identification and location of unpurged releasing fuel and the presence of activation and fission products in the core area. The lessons learned during the reflector block replacement are presented. Operating experience with the primary circuit identifies the lack of mixing of gas streams within the hot plenum and the problems of gas streaming in ducts. Helium leakage from the circuit is often greater than the optimum 0.1%/d. Virtually all the leakage problems are associated with the small bore instrument pipework essential for the many experiments associated with the Dragon Reactor Experiment (DRE). Primary circuit maintenance work confirms the generally clean state of the DRE circuit but identifies 137 Cs and 110 Agsup(m) as possible hazards if fuel emitting these isotopes is irradiated.

Experience Learning and Community Development

Full Text Available Research in the field of education, carried out in living and working environment, which has undergone so profound changes recently, is of extreme importance. In schools, courses and seminars, one cannot prepare him/herself for the changes as these are often so rapid that it is impossible to foresee them. Therefore, one can only learn by experience. In defining the term 'experience learning', the teoreticians vary greatly. In this paper, experience learning is understood as a process of learning taking part mainly outside the planned educational process and including an active and participative attitude towards environment and people. Original and direct experience can thus serve as a basis for gaining new comprehensions, for planning future activities as well as for a reinterpretation of the past experiences. Let us first mention the basic factors of successful experience learning, such as an individual's character features, possibilities for learning, learning atmosphere and positive stimulations. It has been estimated that local community can increase or decrease the possibilities for experience learning. However, the relation is active in other direction too: the more experience learning bas been asserted in a community, the greater its influence on social and cultural development of the community. On has to bear in mind that well-planned education for local community and stimulating sociocultural animation can facilitate the development of local community.

Full Text Available The experience of being a university student (University Experiences had been poorly studied so far. However, research in this field can provide valuable information about the quality of academic life, wellbeing or stress in this population. There is a lack of psychological tests that explore this theoretical construct. The aim of this study was to develop and validate a scale for measuring Univeristy Experiences, for that reason 314 college students were invited to participate for the validation. This students coursed different careers and reported 20 years old as average age. The University Experiences Scale (EExU has adequate psychometric properties. It has a structure of four factors: experience satisfaction, support perception, experience perception and life style adjustment. This factors explain 43.1% of the variance. The grouping of the factors of the College Experience Scale concurs with data reported in the literature about such concept, however this is the first questionnaire designed for measuring it. We anticipate that future studies will seek to verify the performance of the scale in different populations of students and analyze its psychometric properties and its possible association with other psychological variables that affect college students and their health.

Critical experiments at Sandia National Laboratories

International Nuclear Information System (INIS)

Harms, Gary A.; Ford, John T.; Barber, Allison Delo

2010-01-01

Sandia National Laboratories (SNL) has conducted radiation effects testing for the Department of Energy (DOE) and other contractors supporting the DOE since the 1960's. Over this period, the research reactor facilities at Sandia have had a primary mission to provide appropriate nuclear radiation environments for radiation testing and qualification of electronic components and other devices. The current generation of reactors includes the Annular Core Research Reactor (ACRR), a water-moderated pool-type reactor, fueled by elements constructed from UO2-BeO ceramic fuel pellets, and the Sandia Pulse Reactor III (SPR-III), a bare metal fast burst reactor utilizing a uranium-molybdenum alloy fuel. The SPR-III is currently defueled. The SPR Facility (SPRF) has hosted a series of critical experiments. A purpose-built critical experiment was first operated at the SPRF in the late 1980's. This experiment, called the Space Nuclear Thermal Propulsion Critical Experiment (CX), was designed to explore the reactor physics of a nuclear thermal rocket motor. This experiment was fueled with highly-enriched uranium carbide fuel in annular water-moderated fuel elements. The experiment program was completed and the fuel for the experiment was moved off-site. A second critical experiment, the Burnup Credit Critical Experiment (BUCCX) was operated at Sandia in 2002. The critical assembly for this experiment was based on the assembly used in the CX modified to accommodate low-enriched pin-type fuel in water moderator. This experiment was designed as a platform in which the reactivity effects of specific fission product poisons could be measured. Experiments were carried out on rhodium, an important fission product poison. The fuel and assembly hardware for the BUCCX remains at Sandia and is available for future experimentation. The critical experiment currently in operation at the SPRF is the Seven Percent Critical Experiment (7uPCX). This experiment is designed to provide benchmark

Experiments at CERN in 1988

International Nuclear Information System (INIS)

1988-11-01

This book is a compilation of the current experimental programme at CERN. The experiments listed are being performed at one of the following machines: The Super Proton Synchrotron (SPS), the Proton Synchrotron (PS) and the Synchro Cyclotron (SC). The four experiments planned for the Large Electron Positron machine (LEP) are also listed. The schematic layouts of beams and experimental areas at the different machines appear at the beginning of the report. The experiments are briefly described and a schematic layout of each apparatus is included together with lists of participants and institutions. The status of the experiments (preparation/data-taking/completed) corresponds to the situation at the end of 1988. The 'completed' status means that data-taking is finished, not necessarily the analysis of the results; this status is kept for two years and then the experiment is removed from the catalogue. A complete list of all the experiments published in these books since 1974 is given at the end. (orig./HSI)

Data analysis for electronic experiments

International Nuclear Information System (INIS)

Grote, H.

1981-01-01

In this lecture I schell attempt to cover the principal off-line software aspects in electronic experiments. Of course, this is too ambitious an undertaking for two reasons: Firstly the field is vast, and some important aspect will certainly have escaped my attention. Secondly, the choice of methods, features, algorithms, and packages presented will be biased through my personal opinion and experience, although to some extent it is influenced as well by the opinion and experience of my colleagues, who, like myself, are working in this field at CERN. Therefore, beware. Whenever I shall claim something to be evident, a matter of experience -- a fact --it ain't necessarily so. On the other hand, it will not be entirely wrong, since our experience is based on something like 30 experiments in high-energy physics using electronic for other people, and although these people are of course misled, one has to admit their existence.

Fusion neutronics experiments and analysis

International Nuclear Information System (INIS)

1992-01-01

UCLA has led the neutronics R ampersand D effort in the US for the past several years through the well-established USDOE/JAERI Collaborative Program on Fusion Neutronics. Significant contributions have been made in providing solid bases for advancing the neutronics testing capabilities in fusion reactors. This resulted from the hands-on experience gained from conducting several fusion integral experiments to quantify the prediction uncertainties of key blanket design parameters such as tritium production rate, activation, and nuclear heating, and when possible, to narrow the gap between calculational results and measurements through improving nuclear data base and codes capabilities. The current focus is to conduct the experiments in an annular configuration where the test assembly totally surrounds a simulated line source. The simulated line source is the first-of-a-kind in the scope of fusion integral experiments and presents a significant contribution to the world of fusion neutronics. The experiments proceeded through Phase IIIA to Phase IIIC in these line source simulation experiments started in 1989

Authoring Immersive Mixed Reality Experiences

Science.gov (United States)

Misker, Jan M. V.; van der Ster, Jelle

Creating a mixed reality experience is a complicated endeavour. From our practice as a media lab in the artistic domain we found that engineering is “only” a first step in creating a mixed reality experience. Designing the appearance and directing the user experience are equally important for creating an engaging, immersive experience. We found that mixed reality artworks provide a very good test bed for studying these topics. This chapter details three steps required for authoring mixed reality experiences: engineering, designing and directing. We will describe a platform (VGE) for creating mixed reality environments that incorporates these steps. A case study (EI4) is presented in which this platform was used to not only engineer the system, but in which an artist was given the freedom to explore the artistic merits of mixed reality as an artistic medium, which involved areas such as the look and feel, multimodal experience and interaction, immersion as a subjective emotion and game play scenarios.

Staged theta pinch experiments

Linford, R.K.; Downing, J.N.; Gribble, R.F.; Jacobson, A.R.; Platts, D.A.; Thomas, K.S.

1976-01-01

Two implosion heating circuits are being experimentally tested. The principal experiment in the program is the 4.5-m-long Staged Theta Pinch (STP). It uses two relatively low energy (50kJ and 100 kJ), high voltage (125 kV) capacitor banks to produce the theta pinch plasma inside the 20 cm i.d. quartz discharge tube. A lower voltage (50 kV), higher energy (750 kJ) capacitor bank is used to contain the plasma and provide a variable amount of adiabatic compression. Because the experiment produces a higher ratio of implosion heating to compressional heating than conventional theta pinches, it should be capable of producing high temperature plasmas with a much larger ratio of plasma radius to discharge tube radius than has been possible in the past. The Resonant Heating Experiment (RHX) in its initial configuration is the same as a 0.9-m-long section of the high voltage part of the STP experiment and all the plasma results here were obtained with the experiment in that configuration. Part of the implosion bank will be removed and a low inductance crowbar added to convert it to the resonant heating configuration. (U.K.)

The Mobilisatsia experience

International Nuclear Information System (INIS)

De Boever, P.

2005-01-01

The hazards of long-duration manned space flight are real. In order to participate effectively in long duration orbital missions or to continue the exploration of space, the health of the astronaut must be secured. There is mounting evidence that changes in the immune response of an astronaut in short-term flights, resemble those occurring after acute stress, while the changes during long-term flights resemble those caused by chronic stress. This blunting of the immune system occurs concomitant with a relative increase in microbial contamination in the space cabin environment. Such a combination of events results in an increased probability of in-flight infectious events. Micro-organisms are subject to a genetic evolution, which may lead to the capacity to colonize new environments and to cause infections. Central players in this evolutionary process are mobile genetic elements. They help to mobilize and reorganize genes, be it within a given genome (intragenomic mobility) or between bacterial cells (intercellular mobility). Hence, the processes of genetic exchange can mobilize genetic elements between bacterial strains, and therefore play a role in determining the infectious potential. The specific confined environment and space-flight related factors (such as microgravity and cosmic radiation) may increase the frequency in which mobile genetic elements are exchanged between micro organisms. The aim of the Mobilisatsia experiment was to promote microbial gene transfer under space flight conditions during a short-term experiment conducted aboard the International Space Station (ISS). The efficiency of the gene exchange process was compared with a synchronously performed ground control experiment. An experiment was carried out with well-characterized Gram-negative reference strains and one experiment was done with Gram-positive reference strains

The KOSI experiments

International Nuclear Information System (INIS)

Huebner, W.F.

1991-01-01

Whipply's icy conglomerate model of the comet nucleus has enjoyed progressively increasing acceptance and success in explaining Earth-based observations of comets since its very inception (Whipple, 1950, 1951). According to this model, the nucleus is a solid body composed of frozen gases and dust. The missions to Comet Halley in 1986, in particular the Vega and the Giotto missions, have confirmed that there is a single solid nucleus that is the root of all the observed phenomena that can be associated with an active comet. Two new comet mission (CRAF and Rosetta) are planned by NASA and ESA to extract further details about the structure and composition of the nucleus. Laboratory experiments play an important role in defining and identifying the objectives of these missions. Although such experiments have been carried out in many laboratories in Europe, the Soviet Union, the USA, Israel, and Japan, the KOSI experiments are the first large-scale investigations (in spatial dimensions and duration). (KOSI is an acronym for Kometensimulation, German for comet simulation). Starting with a summary and explanation of the KOSI experiments by Grun et al. (1991) and some of the experimental limitations by Keller and Markiewicz (1991), the author reports in this special issue the progress achieved about halfway through the planned series of investigations

The experimental results will be compared to theoretical models under development at Karlsruhe. Commencement of the experiments is expected for the beginning of 1975

Pictures, images, and recollective experience.

Science.gov (United States)

Dewhurst, S A; Conway, M A

1994-09-01

Five experiments investigated the influence of picture processing on recollective experience in recognition memory. Subjects studied items that differed in visual or imaginal detail, such as pictures versus words and high-imageability versus low-imageability words, and performed orienting tasks that directed processing either toward a stimulus as a word or toward a stimulus as a picture or image. Standard effects of imageability (e.g., the picture superiority effect and memory advantages following imagery) were obtained only in recognition judgments that featured recollective experience and were eliminated or reversed when recognition was not accompanied by recollective experience. It is proposed that conscious recollective experience in recognition memory is cued by attributes of retrieved memories such as sensory-perceptual attributes and records of cognitive operations performed at encoding.

Cimesa, S.

2007-01-01

Slovenian Nuclear Safety Administration (SNSA) has developed its own system for tracking, screening and evaluating the operating experiences of the nuclear installations. The SNSA staff regularly tracks the operating experiences throughout the world and screens them on the bases of applicability for the Slovenian nuclear facilities. The operating experiences, which pass the screening, are thoroughly evaluated and also recent operational events in these facilities are taken into account. If needed, more information is gathered to evaluate the conditions of the Slovenian facilities and appropriate corrective actions are considered. The result might be the identification of the need for modification at the licensee, the need for modification of internal procedures in the SNSA or even the proposal for the modification of regulations. Information system helps everybody to track the process of evaluation and proper logging of activities. (author)

Sandia National Laboratories (SNL) has conducted radiation effects testing for the Department of Energy (DOE) and other contractors supporting the DOE since the 1960's. Over this period, the research reactor facilities at Sandia have had a primary mission to provide appropriate nuclear radiation environments for radiation testing and qualification of electronic components and other devices. The current generation of reactors includes the Annular Core Research Reactor (ACRR), a water-moderated pool-type reactor, fueled by elements constructed from UO2-BeO ceramic fuel pellets, and the Sandia Pulse Reactor III (SPR-III), a bare metal fast burst reactor utilizing a uranium-molybdenum alloy fuel. The SPR-III is currently defueled. The SPR Facility (SPRF) has hosted a series of critical experiments. A purpose-built critical experiment was first operated at the SPRF in the late 1980's. This experiment, called the Space Nuclear Thermal Propulsion Critical Experiment (CX), was designed to explore the reactor physics of a nuclear thermal rocket motor. This experiment was fueled with highly-enriched uranium carbide fuel in annular water-moderated fuel elements. The experiment program was completed and the fuel for the experiment was moved off-site. A second critical experiment, the Burnup Credit Critical Experiment (BUCCX) was operated at Sandia in 2002. The critical assembly for this experiment was based on the assembly used in the CX modified to accommodate low-enriched pin-type fuel in water moderator. This experiment was designed as a platform in which the reactivity effects of specific fission product poisons could be measured. Experiments were carried out on rhodium, an important fission product poison. The fuel and assembly hardware for the BUCCX remains at Sandia and is available for future experimentation. The critical experiment currently in operation at the SPRF is the Seven Percent Critical Experiment (7uPCX). This experiment is designed to provide benchmark

Thermal-barrier experiments have been carried out in the Tandem Mirror Experiment-Upgrade (TMX-U). Measurements of nonambipolar and ambipolar radial transport show that these transport processes, as well as end losses, can be controlled at modest densities and durations. Central-cell heating methods using ion-cyclotron heating (ICH) and neutral-beam injection have been demonstrated. Potential mesurements with recently developed methods indicate that deep thermal barriers can be established

Quantitative nature of overexpression experiments

2015-01-01

Overexpression experiments are sometimes considered as qualitative experiments designed to identify novel proteins and study their function. However, in order to draw conclusions regarding protein overexpression through association analyses using large-scale biological data sets, we need to recognize the quantitative nature of overexpression experiments. Here I discuss the quantitative features of two different types of overexpression experiment: absolute and relative. I also introduce the four primary mechanisms involved in growth defects caused by protein overexpression: resource overload, stoichiometric imbalance, promiscuous interactions, and pathway modulation associated with the degree of overexpression.

1999-01-01

This paper describes the microgravity materials experiments carried out on the Shuttle/Mir program. There were six experiments, all of which investigated some aspect of diffusivity in liquid melts. The Liquid Metal Diffusion (LMD) experiment investigated the diffusivity of molten Indium samples at 185 C using a radioactive tracer, In-114m. By monitoring two different gamma ray energies (190 keV and 24 keV) emitted by the samples it was possible to measure independently the diffusion rates in the bulk and at the surface of the samples. The Queens University Experiment in Liquid Diffusion (QUELD) was the furnace facility used to process 213 samples for the five other experiments. These experiments investigated the diffusion, ripening, crystal growth, and glass formation in metal, semiconductor, and glass samples. This facility had the capability to process samples in an isothermal or gradient configuration for varying periods of time at temperatures up to 900 C. Both the LMD and the QUELD furnaces were mounted on the Microgravity Isolation Mount (MIM) which provided isolation from g-jitter. All the microgravity experiments were supported by the Space Acceleration Measurement System (SAMS); a three head three axes acceleration monitoring system which measured and recorded the acceleration environment.

Setting-out of objects on the exploitation field of the mine, both in surface mining and in the underground mines, is determined by the specified setting-out accuracy of reference points, which are best to define spatial position of the object projected. For the purpose of achieving of the specified accuracy, it is necessary to perform a priori accuracy assessment of parameters, which are to be used when performing setting-out. Based on the a priori accuracy assessment, verification of the quality of geometrical setting- -out elements specified in the layout; definition of the accuracy for setting-out of geometrical elements; selection of setting-out method; selection at the type and class of instruments and tools that need to be applied in order to achieve predefined accuracy. The paper displays the accuracy assessment of geometrical elements for setting-out of the main haul gallery, haul downcast and helical conveying downcasts in shape of an inclined helix in horizontal plane, using the example of the underground bauxite mine »Kosturi«, Srebrenica. Wytyczanie obiektów na polu wydobywczym w kopalniach, zarówno podziemnych jak i odkrywkowych, zależy w dużej mierze od określonej dokładności wytyczania punktów referencyjnych, przy pomocy których określane jest następnie położenie przestrzenne pozostałych obiektów. W celu uzyskania założonej dokładności, należy przeprowadzić wstępną analizę dokładności oszacowania parametrów które następnie wykorzystane będą w procesie wytyczania. W oparciu o wyniki wstępnej analizy dokładności dokonuje się weryfikacji jakości geometrycznego wytyczenia elementów zaznaczonych na szkicu, uwzględniając te wyniki dobrać należy odpowiednią metodę wytyczania i rodzaj oraz klasę wykorzystywanych narzędzi i instrumentów, tak by osiągnąć założony poziom dokładności.

RACE (Ring ACceleration Experiment) is a proof-of-principle experiment aimed at demonstrating acceleration of magnetically confined compact torus plasma rings to directed kinetic energies well in excess of their magnetic and thermal energies. In the course of the first year of operation the following have been observed: successful formation of rings in the RACE geometry; acceleration of rings with large forces, F/sub accelerate/ ∼F/sub equilibrium/ without apparent degradation of the ring structure; peak velocities of ≅2.5 x 10 8 cm/sec; acceleration efficiency of >30% at speeds of 1.5 x 10 8 cm/sec inferred from trajectory and capacitor bank data; kinetic to magnetic energy ratios ∼10 were observed. Experiments in the near future will be aimed at confirmation of the mass/energy measurements by calorimetry and direct density measurements

Neutrinoless Double Beta Decay Experiments

International Nuclear Information System (INIS)

Garfagnini, A.

2014-08-01

Neutrinoless double beta decay is the only process known so far able to test the neutrino intrinsic nature: its experimental observation would imply that the lepton number is violated by two units and prove that neutrinos have a Majorana mass components, being their own anti-particle. While several experiments searching for such a rare decay have been per- formed in the past, a new generation of experiments using different isotopes and techniques have recently released their results or are taking data and will provide new limits, should no signal be observed, in the next few years to come. The present contribution reviews the latest public results on double beta decay searches and gives an overview on the expected sensitivities of the experiments in construction which will be able to set stronger limits in the near future. EXO and KamLAND-Zen experiments are based on the decay of Xe 136 , GERDA and MAJORANA experiments are based on the decay of Ge 76 , and the CUORE experiment is based on the decay of Te 130

The Cosmics Leaving Outdoor Droplets (CLOUD) experiment as shown by Jasper Kirkby (spokesperson). Kirkby shows a sketch to illustrate the possible link between galactic cosmic rays and cloud formations. The CLOUD experiment uses beams from the PS accelerator at CERN to simulate the effect of cosmic rays on cloud formations in the Earth's atmosphere. It is thought that cosmic ray intensity is linked to the amount of low cloud cover due to the formation of aerosols, which induce condensation.

In the process of preparing for pyrophoricity experiments involving uranium, we conducted hydriding and air-exposure experiments on titanium. In these experiments the hydriding reactions and response to air-exposure was generally within the range expected based on work reported by others. One aberrant behavior was a sudden weight gain followed by a significant weight loss. We speculate that loss may be due to hydrogen evolution from the TiH 2 resulting from local heating by oxidation reactions. We verified that titanium is not pyrophoric at temperatures less than 750 degree C. 18 refs. 1 fig

Perceptual Experience and Seeing-as

Directory of Open Access Journals (Sweden)

Daniel Enrique Kalpokas

2015-07-01

Full Text Available According to Rorty, Davidson and Brandom, to have an experience is to be caused by our senses to hold a perceptual belief. This article argues that the phenomenon of seeing-as cannot be explained by such a conception of perceptual experience. First, the notion of experience defended by the aforementioned authors is reconstructed. Second, the main features of what Wittgenstein called “seeing aspects” are briefly presented. Finally, several arguments are developed in order to support the main thesis of the article: seeing-as cannot be explained by the conception of experience defended by Rorty, Davidson and Brandom.

Prospects in coincidence experiments

International Nuclear Information System (INIS)

Laget, J.M.

1984-01-01

The sensitivity of virtual photons to the local variations of the charge and magnetization densities is exploited to study the short-range part of the nucleon-nucleon interaction inside the nucleus. The possibility of varying energy, squared mass and longitudinal polarization of the photons independently enables us to disentangle the mechanisms related to the internal structure of the nucleon (e.g. quark interchange) and the contribution due to meson exchange. Coincidence experiments of the type (e,e'N) and (e,e'NN) are performed to suppress the meson contribution to the longitudinal part of the quasi-elastic peak. Four typical examples of coincidence experiments induced by virtual photons are discussed: experiments (1) on the spectroscopic structure of the quasi-elastic peak and the problem of deep lying hole states; (2) on the structure of the continuum; (3) on the low energy side of the quasi-elastic peak; and finally a three-arm coincidence experiment.

Muon ionization cooling experiment

CERN Multimedia

CERN. Geneva

2003-01-01

A neutrino factory based on a muon storage ring is the ultimate tool for studies of neutrino oscillations, including possibly leptonic CP violation. It is also the first step towards muon colliders. The performance of this new and promising line of accelerators relies heavily on the concept of ionisation cooling of minimum ionising muons, for which much R&D is required. The concept of a muon ionisation cooling experiment has been extensively studied and first steps are now being taken towards its realisation by a joint international team of accelerator and particle physicists. The aim of the workshop is to to explore at least two versions of an experiment based on existing cooling channel designs. If such an experiment is feasible, one shall then select, on the basis of effectiveness, simplicity, availability of components and overall cost, a design for the proposed experiment, and assemble the elements necessary to the presentation of a proposal.

The AEGIS experiment (Antihydrogen Experiment: Gravity, Interferometry, Spectroscopy) has the aim of carrying out the first measurement of the gravitational interaction of antimatter to a precision of 1%, by applying techniques from atomic physics, laser spectroscopy and interferometry to a beam of antihydrogen atoms. A further goal of the experiment is to carry out spectroscopy of the antihydrogen atoms in flight.

Experiments on hot-electron ECRH in the Tandem Mirror Experiment-Upgrade

International Nuclear Information System (INIS)

Stallard, B.W.

1983-01-01

Experiments have begun on the Tandem Mirror Experiment Upgrade (TMX-U) using electron-cyclotron resonant heating (ECRH) to generate the hot electron populations required for thermal barrier operation (Energy E/sub eh/ approx. 50 keV, density n/sub eh/ 12 , and hot-to-cold fraction n/sub eh/n approx. 0.9). For this operation, rf power produced by 28-GHz gyrotrons is injected with extraordinary mode polarization at both fundamental and second harmonic locations. Our initial experiments, which concentrated on startup of the hot electrons, were carried out at low density ( 12 cm - 3 ) where Fokker-Planck calculations predict high heating efficiency when the electron temperature (T/sub e/) is low. Under these conditions, we produced substantial hot electron populations (diamagnetic energy > 400 J, E/sub eh/ in the range of 15 to 50 keV, and n/sub eh//n > 0.5)

Operating Experience at NPP Krsko

International Nuclear Information System (INIS)

Kavsek, D.; Bach, B.

1998-01-01

Systematic analysis of operational experience by assessment of internal and industry events and the feedback of lessons learned is one of the essential activities in the improvement of the operational safety and reliability of the nuclear power plant. At NPP Krsko we have developed a document called ''Operating Experience Assessment Program''. Its purpose is to establish administrative guidance for the processing of operating events including on-site and industry events. Assessment of internal events is based on the following methods: Event and Causal Factor Charting, Change Analysis, Barrier Analysis, MORT (Management Oversight and Risk Tree Analysis) and Human Performance Evaluation. The operating experience group has developed a sophisticated program entitled ''Operating experience tracking system'' (OETS) in response to the need for a more efficient way of processing internal and industry operating experience information. The Operating Experience Tracking System is used to initiate and track operational events including recommended actions follow up. Six screens of the system contain diverse essential information which allows tracking of operational events and enables different kinds of browsing. OETS is a part of the NPP Krsko nuclear network system and can be easily accessed by all plant personnel. (author)

[Turnover Experience of Male Nurses].

Science.gov (United States)

Kim, Hyunsu; Lee, Jeongseop

2017-02-01

The aim of this study was to identify turnover experiences of men in nursing and to derive a substantive theory on the turnover experience of men who are nurses. Data were collected through in-depth interviews with 13 men who had worked as a nurse for 1 year or more, and had a turnover experience during that period. Collected data were analyzed on the basis of Strauss and Corbin's grounded theory. The core category in the turnover experiences of the respondents was 'seeking a stable place for me'. In the analysis of the core category, types of 'contentment', 'seeking', 'survival' and 'confusion' were identified. The sequential stages of these nurses' turnover experience were 'confrontation', 'incertitude', 'retrying' and 'realization'. However, when a problem arose in the process, they returned to the stage of confusion. Thus, these stages could occur in a circular fashion. These findings provide a deep understanding of the turnover experience of men in nursing and offers new information about how they adapt to nursing practice. The findings should be useful as foundational data for men who hope to become nurses and also for managers responsible for nurses who are men. © 2017 Korean Society of Nursing Science

In order to investigate dynamics of the reactor plant of the nuclear ship Mutsu, the second reactor noise experiment using pseudo random binary sequences (PRBS) was performed on August 30, 1991 in the third experimental navigation. The experiments using both reactivity and load disturbances were performed at 50% of reactor power and under a quiet sea condition. Each PRBS was applied by manual operation of the control rod or the main steam valve. Various signals of the plant responses and of the acceleration of ship motion were measured. Furthermore, natural reactor noise signals were measured after each PRBS experiment in order to evaluate the effects of the PRBS disturbances. This paper summarizes the planning of the experiment, the instruction for the experiment and logs, the data recording conditions, recorded signal wave forms and the results of power spectral analysis.

Design and analysis of experiments

CERN Document Server

Dean, Angela; Draguljić, Danel

2017-01-01

This textbook takes a strategic approach to the broad-reaching subject of experimental design by identifying the objectives behind an experiment and teaching practical considerations that govern design and implementation, concepts that serve as the basis for the analytical techniques covered. Rather than a collection of miscellaneous approaches, chapters build on the planning, running, and analyzing of simple experiments in an approach that results from decades of teaching the subject. In most experiments, the procedures can be reproduced by readers, thus giving them a broad exposure to experiments that are simple enough to be followed through their entire course. Outlines of student and published experiments appear throughout the text and as exercises at the end of the chapters. The authors develop the theory of estimable functions and analysis of variance with detail, but at a mathematical level that is simultaneously approachable. Throughout the book, statistical aspects of analysis complement practical as...

A pobreza de experiência

Adolfo Junior Pereira

2016-12-01

Full Text Available Esse artigo pretende uma interpretação do texto Experiência e pobreza de Walter Benjamin. A experiência, para ele, é necessariamente devedora do modo como opera a transmissão. E a transmissão, devedora de um trabalho de velamento sobre um furo de sentido arcaico na linguagem e na cultura que determina o modo como experimentamos o tempo historicamente vivido. A transmissão se apresenta, assim, como o nexo temporal da experiência. Esse nexo não se funda em relações de causa e efeito, é um nexo de culpa. É nesse sentido que Benjamin pode ver com um bom olhar político a pobreza de experiência da vida moderna. Dentro daquilo que chamou de nova barbárie demonstra uma experiência que pode redimir nossa dívida com o passado.

How training and experience affect the benefits of autonomy in a dirty-bomb experiment

Energy Technology Data Exchange (ETDEWEB)

David J. Bruemmer; Curtis W. Nielsen; David I. Gertman

2008-03-01

A dirty-bomb experiment conducted at the INL is used to evaluate the effectiveness and suitability of three different modes of robot control. The experiment uses three distinct user groups to understand how participants’ background and training affect the way in which they use and benefit from autonomy. The results show that the target mode, which involves automated mapping and plume tracing together with a point and click tasking tool, provides the best performance for each group. This is true for objective performance such as source detection and localization accuracy as well as subjective measures such as perceived workload, frustration and preference. The best overall performance is achieved by the Explosive Ordinance Disposal group which has experience in both robot teleoperation and dirty bomb response. The user group that benefits least from autonomy is the Nuclear Engineers that have no experience with either robot operation or dirty bomb response. The group that benefits most from autonomy is the Weapons of Mass Destruction Civil Response Team that has extensive experience related to the task, but no robot training.

The Red Sage campaign is a series of subcritical dynamic plutonium experiments designed to measure ejecta. Nightshade, the first experiments in Red Sage scheduled for fiscal year 2019, will measure the amount of ejecta emission into vacuum from a double-­shocked plutonium surface. To address the major technical risks in Nightshade, a Level 2 milestone was developed for fiscal year 2016. Silverleaf, a series of four experiments, was executed at the Los Alamos National Laboratory in July and August 2016 to demonstrate a prototype of the Nightshade package and to satisfy this Level 2 milestone. This report is documentation that Red Sage Level 2 milestone requirements were successfully met.

Popper's Experiment: A Modern Perspective

Directory of Open Access Journals (Sweden)

Tabish Qureshi

2012-11-01

Full Text Available Karl Popper had proposed an experiment to test the standard interpretation of quantum mechanics. The proposal survived for many year in the midst of no clear consensus on what results it would yield. The experiment was realized by Kim and Shih in 1999, and the apparently surprising result led to lot of debate. We review Popper's proposal and its realization in the light of current era when entanglement has been well studied, both theoretically and experimentally. We show that the "ghost-diffraction" experiment, carried out in a different context, conclusively resolves the controversy surrounding Popper's experiment. Quanta 2012; 1: 19–32.

Experiment data report for LOFT anticipated transient-without-scram Experiment L9-3

Bayless, P.D.; Divine, J.M.

1982-05-01

Selected pertinent and uninterpreted data from the third anticipated transient with multiple failures experiment (Experiment L9-3) conducted in the Loss-of-Fluid Test (LOFT) facility are presented. The LOFT facility is a 50-MW(t) pressurized water reactor (PWR) system with instruments that measure and provide data on the system thermal-hydraulic and nuclear conditions. The operation of the LOFT system is typical of large [approx. 1000 MW(e)], commercial PWR operations. Experiment L9-3 simulated a loss-of-feedwater anticipated transient without scram. The loss-of-feedwater accident led to an increase in the primary coolant system temperature and pressure. Both the experiment power-operated relief valve (PORV) and safety relief valve opened and were able to limit and control the pressure transient. The plant was then recovered with the control rods still withdrawn by injecting 7200-ppM borated water, manually cycling the PORV and feeding and bleeding the steam generator

2004-01-01

A set of experiments has been performed on the High-Current Experiment (HCX) facility at LBNL, in which the ion beam is allowed to collide with an end plate and thereby induce a copious supply of desorbed electrons. Through the use of combinations of biased and grounded electrodes positioned in between and downstream of the quadrupole magnets, the flow of electrons upstream into the magnets can be turned on or off. Properties of the resultant ion beam are measured under each condition. The experiment is modeled via a full three-dimensional, two species (electron and ion) particle simulation, as well as via reduced simulations (ions with appropriately chosen model electron cloud distributions, and a high-resolution simulation of the region adjacent to the end plate). The three-dimensional simulations are the first of their kind and the first to make use of a timestep-acceleration scheme that allows the electrons to be advanced with a timestep that is not small compared to the highest electron cyclotron period. The simulations reproduce qualitative aspects of the experiments, illustrate some unanticipated physical effects, and serve as an important demonstration of a developing simulation capability

Laboratory experiments to test relativistic gravity

Braginsky, V.B.; Caves, C.M.; Thorne, K.S.

1977-01-01

Advancing technology will soon make possible a new class of gravitation experiments: pure laboratory experiments with laboratory sources of non-Newtonian gravity and laboratory detectors. This paper proposes seven such experiments; and for each one it describes, briefly, the dominant sources of noise and the technology required. Three experiments would utilize a high-Q torque balance as the detector. They include (i) an ''Ampere-type'' experiment to measure the gravitational spin-spin coupling of two rotating bodies, (ii) a search for time changes of the gravitation constant, and (iii) a measurement of the gravity produced by magnetic stresses and energy. Three experiments would utilize a high-Q dielectric crystal as the detector. They include (i) a ''Faraday-type'' experiment to measure the ''electric-type'' gravity produced by a time-changing flux of ''magnetic-type'' gravity, (ii) a search for ''preferred-frame'' and ''preferred-orientation'' effects in gravitational coupling, and (iii) a measurement of the gravitational field produced by protons moving in a storage ring at nearly the speed of light. One experiment would use a high-Q toroidal microwave cavity as detector to search for the dragging of inertial frames by a rotating body

Cognitive Processes Underlying the Artistic Experience

Directory of Open Access Journals (Sweden)

Alejandra Wah

2017-08-01

Full Text Available Based on the field of aesthetics, for centuries philosophers and more recently scientists have been concerned with understanding the artistic experience focusing on emotional responses to the perception of artworks. By contrast, in the last decades, evolutionary biology has been concerned with explaining the artistic experience by focusing on the cognitive processes underlying this experience. Up until now, the cognitive mechanisms that allow humans to experience objects and events as art remain largely unexplored and there is still no conventional use of terms for referring to the processes which may explain why the artistic experience is characteristically human and universal to human beings (Dissanayake, 1992, p. 24; Donald, 2006, p. 4. In this paper, I will first question whether it is productive to understand the artistic experience in terms of perception and emotion, and I will subsequently propose a possible alternative explanation to understand this experience. Drawing upon the work of Ellen Dissanayake (1992, 2000, 2015, Merlin Donald (2001, 2006, 2013, Antonio Damasio (1994, 2000, 2003, 2010, Barend van Heusden (2004, 2009, 2010, and Alejandra Wah (2014, I will argue that this experience is characterized by particular degrees of imagination and consciousness.

Ignition experiment - alternatives

International Nuclear Information System (INIS)

Knobloch, A.F.

1979-10-01

This report comprises three short papers on cost estimates, integral burn time and alternative versions of Tokamak ignition experiments. These papers were discussed at the ZEPHYR workshop with participants from IPP Garching, MIT Cambridge and PPPL Princeton (Garching July 30 - August 2 1979) (Chapters A, B, C). It is shown, that starting from a practical parameter independent minimum integral burn time of Tokamak ignition experiments (some 10 3 s) by adding a shield for protection of the magnet insulation (permitted neutron dose 10 9 rad) an integral burn time of some 10 4 s can be achieved for only about 30% more outlay. For a substantially longer integral burn time the outlay approaches rather quickly that for a Tokamak reactor. Some examples for alternatives to ZEPHYR are being given, including some with low or no compression. In a further chapter D some early results of evaluating an ignition experiment on the basis of the energy confinement scaling put forward by Coppi and Mazzucato are presented. As opposed to the case of the Alcator scaling used in chapters A through C the minimum integral burn time of Tokamak ignition experiments here depends on the plasma current. Provided neutral injectors up to about 160 keV are available compression boosting is not required with this scaling. The results presented have been obtained neglecting the effects of the toroidal field ripple. (orig.) 891 HT/orig. 892 RKD [de

This report presents uninterpreted experimental data from the second, third, and fourth anticipated transient experiments (Experiments L6-2, L6-1, and L6-3), conducted in the Loss-of-Fluid Test (LOFT) facility. Experiment L6-2 simulated a loss of forced primary coolant flow in a large PWR by tripping power to primary coolant pump motor generator sets, allowing the pumps to coast down under the influence of the flywheel system. Reactor scram initiated on indication of low flow in the primary coolant system (PCS). Experiment L6-1 simulated a loss of steam load in a large PWR by closing the steam flow control valve which reduced heat removal from the secondary coolant system and caused the PCS temperature and pressure to increase until reactor scram initiated on indication on high PCS pressure. Experiment L6-3 simulated an excessive load increase in a large PWR by opening the steam flow control valve at its maximum rate. PCS temperature and pressure decreased, causing the reactor to scram on indication of low PCS pressure. All experiments were complete when the plant was returned to a hot-standby condition

Critical experiments AT Pacific Northwest Laboratory

International Nuclear Information System (INIS)

Clayton, E.D.; Bierman, S.R.

1984-01-01

After a short description of the facility, a brief listing of the principal types of fuel forms and assembly geometries is provided. A number of experiments have recently been performed on plain fissionable units, or isolated assemblies of single units, that include measurements on solutions composed of Pu-U mixtures and critical experiment data on lattices of low enriched uranium in water. Experiments have been performed on planar arrays of containers with Pu solutions because of the lack of data in this field concerning the safe storage of nuclear fuel; others have been conducted on arrays of low enriched U lattice assemblies. Neutronic measurements to date have shown they can be used to provide additional benchmark data for improvement and validation of criticality codes. Studies have previously been made to ascertain the need for critical experiments in support of fuel recycle operations. The result of an effort to update the list of needed critical experiments is summarized in this section. Experiments are listed in support of uranium based fuels and fast breeder reactor fuels. An effort is made to identify those areas within the fuel cycle wherein the critical experiment data would be applied and to identify the experiments (and data) required to fulfill the needs in each of these areas. The type and form of fuel on which the data would be obtained also are identified. In presenting this information, no attempt is made to describe the experiments in detail, or to define the actual number of critical experiments that might be needed to provide the required data

Human spaceflight hardware and operations must comply with NSTS 1700.7. This paper discusses how a glovebox can help.A short layout is given on the process according NSTS/ISS 13830, explaining the responsibility of the payload organization, the approval authority of the PSRP and the defined review phases (0 till III).Amongst others, the following requirement has to be met:"200.1 Design to Tolerate Failures. Failure tolerance is the basic safety requirement that shall be used to control most payload hazards. The payload must tolerate a minimum number of credible failures and/or operator errors determined by the hazard level. This criterion applies when the loss of a function or the inadvertent occurrence of a function results in a hazardous event.200.1a Critical Hazards. Critical hazards shall be controlled such that no single failure or operator error can result in damage to STS/ISS equipment, a nondisabling personnel injury, or the use of unscheduled safing procedures that affect operations of the Orbiter/ISS or another payload.200.1b Catastrophic Hazards. Catastrophic hazards shall be controlled such that no combination of two failures or operator errors can result in the potential for a disabling or fatal personnel injury or loss of the Orbiter/ISS, ground facilities or STS/ISS equipment."For experiments in material science, biological science and life science that require real time operator manipulation, the above requirement may be hard or impossible to meet. Especially if the experiment contains substances that are considered hazardous when released into the habitable environment. In this case operation of the experiment in a glovebox can help to comply.A glovebox provides containment of the experiment and at the same time allows manipulation and visibility to the experiment.The containment inside the glovebox provides failure tolerance because the glovebox uses a negative pressure inside the working volume (WV). The level of failure tolerance is dependent of

A Coulomb null experiment is described that enables physics students to obtain rigorous upper bounds on photon mass. The experimenter searches for subnanovolt signals that would escape a closed shell were photon mass to be positive. The approach can be adapted for several college levels. At the simplest level, a ''miniature'' low-cost experiment allows a student to verify the exponent ''-2'' in Coulomb's law to eight or more decimal places. An advanced student given a full-size apparatus (at greater cost) can obtain mass bounds very close to the established laboratory limit

The Florida Footprint experiments were a series of field programs in which perfluorocarbon tracers were released in different configurations centered on a flux tower to generate a data set that can be used to test transport and dispersion models. These models are used to determine the sources of the CO{sub 2} that cause the fluxes measured at eddy covariance towers. Experiments were conducted in a managed slash pine forest, 10 km northeast of Gainesville, Florida, in 2002, 2004, and 2006 and in atmospheric conditions that ranged from well mixed, to very stable, including the transition period between convective conditions at midday to stable conditions after sun set. There were a total of 15 experiments. The characteristics of the PFTs, details of sampling and analysis methods, quality control measures, and analytical statistics including confidence limits are presented. Details of the field programs including tracer release rates, tracer source configurations, and configuration of the samplers are discussed. The result of this experiment is a high quality, well documented tracer and meteorological data set that can be used to improve and validate canopy dispersion models.

The Undergraduate Teaching Assistant Experience Offers Opportunities Similar to the Undergraduate Research Experience

Full Text Available There has been a growing concern in higher education about our failure to produce scientifically trained workers and scientifically literate citizens. Active-learning and research-oriented activities are posited as ways to give students a deeper understanding of science. We report on an undergraduate teaching assistant (UTA experience and suggest that students who participate as a UTA obtain benefits analogous to those who participate as an undergraduate research assistant (URA. We examined the experiences of 24 undergraduates acting as UTAs in a general microbiology course. Self-reported gains by the UTAs were supported by observational data from undergraduates in the course who were mentored by the UTAs and by the graduate teaching assistants (GTAs with whom the UTAs worked. Specifically, data from the UTAs’ journals and self-reported Likert scales and rubrics indicated that our teaching assistants developed professional characteristics such as self-confidence and communication and leadership skills, while they acquired knowledge of microbiology content and laboratory skills. Data from the undergraduate Likert scale as well as the pre- and post-GTA rubrics further confirmed our UTA’s data interpretations. These findings are significant because they offer empirical data to support the suggestion that the UTA experience is an effective option for developing skills and knowledge in undergraduates that are essential for careers in science. The UTA experience provides a valuable alternative to the URA experience.

A MHD experiment is being constructed which will have the possibility of showing dynamo action: the self--generation of currents from fluid motion. The design allows sufficient experimental flexibility and diagnostic access to study a variety of issues central to dynamo theory, including mean--field electrodynamics and saturation (backreaction physics). Initially, helical flows required for dynamo action will be driven by propellers embedded in liquid sodium. The flow fields will first be measured using laser doppler velocimetry in a water experiment with an identical fluid Reynolds number. The magnetic field evolution will then be predicted using a MHD code, replacing the water with sodium; if growing magnetic fields are found, the experiment will be repeated with sodium.

Stratospheric Controlled Perturbation Experiment (SCoPEx), is a scientific experiment to advance understanding of stratospheric aerosols. It aims to make quantitative measurements of aerosol microphysics and atmospheric chemistry to improve large-scale models used to assess the risks and benefits of solar geoengineering. A perturbative experiment requires: (a) means to create a well-mixed, small perturbed volume, and (b) observation of time evolution of chemistry and aerosols in the volume. SCoPEx will used a propelled balloon gondola containing all instruments and drive system. The propeller wake forms a well-mixed volume (roughly 1 km long and 100 meters in diameter) that serves as an experimental `beaker' into which aerosols (e.g., budget, etc; (d) results from CFD simulation of propeller wake and simulation of chemistry and aerosol microphysics; and finally (e) proposed concept of operations and schedule. We will also provide an overview of the plans for governance including management of health safety and environmental risks, transparency, public engagement, and larger questions about governance of solar geoengineering experiments. Finally, we will briefly present results of laboratory experiments of the interaction of chemical such as ClONO2 and HCl on particle surfaces relevant for stratospheric solar geoengineering.

DIRAC in Large Particle Physics Experiments

2017-10-01

The DIRAC project is developing interware to build and operate distributed computing systems. It provides a development framework and a rich set of services for both Workload and Data Management tasks of large scientific communities. A number of High Energy Physics and Astrophysics collaborations have adopted DIRAC as the base for their computing models. DIRAC was initially developed for the LHCb experiment at LHC, CERN. Later, the Belle II, BES III and CTA experiments as well as the linear collider detector collaborations started using DIRAC for their computing systems. Some of the experiments built their DIRAC-based systems from scratch, others migrated from previous solutions, ad-hoc or based on different middlewares. Adaptation of DIRAC for a particular experiment was enabled through the creation of extensions to meet their specific requirements. Each experiment has a heterogeneous set of computing and storage resources at their disposal that were aggregated through DIRAC into a coherent pool. Users from different experiments can interact with the system in different ways depending on their specific tasks, expertise level and previous experience using command line tools, python APIs or Web Portals. In this contribution we will summarize the experience of using DIRAC in particle physics collaborations. The problems of migration to DIRAC from previous systems and their solutions will be presented. An overview of specific DIRAC extensions will be given. We hope that this review will be useful for experiments considering an update, or for those designing their computing models.

2018-05-08

Digital interventions offer an innovative way to make the experiences of people living with mental illness available to others. As part of the Self-Management And Recovery Technology (SMART) research program on the use of digital resources in mental health services, an interactive website was developed including videos of people with lived experience of mental illness discussing their recovery. These peer videos were designed to be watched on a tablet device with a mental health worker, or independently. Our aim was to explore how service users experienced viewing the lived experience videos on this interactive website, as well as its influence on their recovery journey. In total, 36 service users with experience of using the website participated in individual semistructured qualitative interviews. All participants had experience of psychosis. Data analysis occurred alongside data collection, following principles of constructivist grounded theory methodology. According to participants, engaging with lived experience videos was a pivotal experience of using the website. Participants engaged with peers through choosing and watching the videos and reflecting on their own experience in discussions that opened up with a mental health worker. Benefits of seeing others talking about their experience included "being inspired," "knowing I'm not alone," and "believing recovery is possible." Experiences of watching the videos were influenced by the participants' intrapersonal context, particularly their ways of coping with life and use of technology. The interpersonal context of watching the videos with a worker, who guided website use and facilitated reflection, enriched the experience. Engaging with lived experience videos was powerful for participants, contributing to their feeling connected and hopeful. Making websites with lived experience video content available to service users and mental health workers demonstrates strong potential to support service users' recovery

Organizational citizenship behavior and work experience.

Kegans, Loyd; McCamey, Randy B; Hammond, Honor

2012-01-01

The authors compared the relationship of elements of the Organizational Citizenship Behavior (OCB) and years of work experience of registered nurses in the state of Texas. Work experience research has shown a relationship between OCB and work experience through mediating roles of various work related characteristics does exist. Work experience is described as the overall length of time in an occupation or workforce. Civic virtue was the only element of organizational citizenship behavior to have a statistically significant correlation with years of work experience in this study. Other elements were found to have no statistically significant correlation with years of work experience. Further research should be undertaken to determine if correlations between these two constructs holds up when the population under study is further refined by job classification, such as management and staff, or industry segment.

Verification of methods for analysis of radiation-transport (shielding) problems in Liquid-Metal Fast Breeder Reactors has required a series of experiments that can be classified as benchmark, parametric, or design-confirmation experiments. These experiments, performed at the Oak Ridge Tower Shielding Facility, have included measurements of neutron transport in bulk shields of sodium, steel, and inconel and in configurations that simulate lower axial shields, pipe chases, and top-head shields. They have also included measurements of the effects of fuel stored within the reactor vessel and of gamma-ray energy deposition (heating). The paper consists of brief comments on these experiments, and also on a recent experiment in which neutron streaming problems in a Gas-Cooled Fast Breeder Reactor were studied. The need for additional experiments for a few areas of LMFBR shielding is also cited

The main objective of DIRAC experiment is the measurement of the lifetime τ of the exotic hadronic atom consisting of π + and π - mesons. The lifetime of this atom is determined by the decay mode π + π - → π 0 π 0 due to the strong interaction. Through the precise relationship between the lifetime and the S-wave pion-pion scattering length difference |a 0 - a 2 | for isospin 0 and 2 (respectively), a measurement of τ with an accuracy of 10% will allow a determination of |a 0 - a 2 | at a 5% precision level. Pion-pion scattering lengths have been calculated in the framework of chiral perturbation theory with an accuracy below 5%. In this way DIRAC experiment will provide a crucial test of the chiral symmetry breaking scheme in QCD effective theories at low energies

Heaney, Mike

2016-09-13

Statistically designed experiments can save researchers time and money by reducing the number of necessary experimental trials, while resulting in more conclusive experimental results. Surprisingly, many researchers are still not aware of this efficient and effective experimental methodology. As reported in a 2013 article from Chemical & Engineering News, there has been a resurgence of this methodology in recent years (http://cen.acs.org/articles/91/i13/Design-Experiments-Makes-Comeback.html?h=2027056365). This presentation will provide a brief introduction to statistically designed experiments. The main advantages will be reviewed along with the some basic concepts such as factorial and fractional factorial designs. The recommended sequential approach to experiments will be introduced and finally a case study will be presented to demonstrate this methodology.

The Opalinus Clay (OPA) formation in the Zurcher Weiland (Switzerland) is a potential host rock for a repository for high-level radioactive waste. Samples collected in the Mont Terri Underground Rock Laboratory (URL), where the OPA formation is located at a depth between -200 and -300 m below the surface, were used to study the radionuclide diffusion in clay materials. Classical laboratory essays and a novel experimental set-up for large-scale diffusion experiments were performed together to a novel application of the nuclear ion beam technique Rutherford Backscattering Spectrometry (RBS), to understand the transport properties of the OPA and to enhance the methodologies used for in situ diffusion experiments. Through-Diffusion and In-Diffusion conventional laboratory diffusion experiments were carried out with HTO, 36{sup C}l-, I-, 22{sup N}a, 75{sup S}e, 85{sup S}r, 233{sup U}, 137{sup C}s, 60{sup C}o and 152{sup E}u. Large-scale diffusion experiments were performed with HTO, 36{sup C}l, and 85{sup S}r, and new experiments with 60{sup C}o, 137{sup C}s and 152{sup E}u are ongoing.

The global need for lived experience leadership.

Science.gov (United States)

Byrne, Louise; Stratford, Anthony; Davidson, Larry

2018-03-01

Common challenges and experiences of the lived experience/peer workforce globally are considered, with an emphasis on ensuring that future developments both protect and promote the unique lived experience perspective. In the Western world, rapid growth in lived experience roles has led to an urgent need for training and workforce development. However, research indicates the roles risk being coopted without clear lived experience leadership, which is often not occurring. In developing countries and in many Western contexts, the lived experience role has not yet been accepted within the mental health workforce. The need for lived experience leadership to guide these issues is highlighted. Peer-reviewed research, relevant gray literature, and professional experience in countries where little published material currently exists. A window of opportunity currently exists to maximize lived experience leadership, and that window may be closing fast if broad-based actions are not initiated now.

This addendum report documents the results of two additional efforts for the Rocket Based Combined Cycle (RBCC) rocket-ejector mode research work carried out at the Penn State Propulsion Engineering Research Center in support of NASA s technology development efforts for enabling 3 d generation Reusable Launch Vehicles (RLV). The tasks reported here build on an earlier NASA MSFC funded research program on rocket ejector investigations. The first task investigated the improvements of a gaseous hydrogen/oxygen twin thruster RBCC rocket ejector system over a single rocket system. The second task investigated the performance of a hydrocarbon (liquid JP-7)/gaseous oxygen single thruster rocket-ejector system. To gain a systematic understanding of the rocket-ejector s internal fluid mechanic/combustion phenomena, experiments were conducted with both direct-connect and sea-level static diffusion and afterburning (DAB) configurations for a range of rocket operating conditions. For all experimental conditions, overall system performance was obtained through global measurements of wall static pressure profiles, heat flux profiles and engine thrust. Detailed mixing and combustion information was obtained through Raman spectroscopy measurements of major species (gaseous oxygen, hydrogen, nitrogen and water vapor) for the gaseous hydrogen/oxygen rocket ejector experiments.

After the first production of cold antihydrogen by the ATHENA and ATRAP experiments ten years ago, new second-generation experiments are aimed at measuring the fundamental properties of this anti-atom. The goal of AEGIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is to test the weak equivalence principle by studying the gravitational interaction between matter and antimatter with a pulsed, cold antihydrogen beam. The experiment is currently being assembled at CERN's Antiproton Decelerator. In AEGIS, antihydrogen will be produced by charge exchange of cold antiprotons with positronium excited to a high Rydberg state (n > 20). An antihydrogen beam will be produced by controlled acceleration in an electric-field gradient (Stark acceleration). The deflection of the horizontal beam due to its free fall in the gravitational field of the earth will be measured with a moire deflectometer. Initially, the gravitational acceleration will be determined to a precision of 1%, requiring the detection of about 10{sup 5} antihydrogen atoms. In this paper, after a general description, the present status of the experiment will be reviewed.

Thought experiment with tritium

Anderson, H.F.; Everhart, J.L.; Hobrock, D.L.; Seabaugh, P.W.

1995-01-01

An experiment is proposed in which a minimum of thirty (30) grams of tritium is packaged as lithium tritide in a steel container weighing several kilograms. After decontamination of the outside surface, calorimetry measurements would be made, and the unit would be weighed very accurately. After several decades, the calorimeter and weight measurements would be repeated. If the weight measurements could be made with the required accuracy, it would be possible to correlate the observed change in mass with the total energy emitted (calculated from the mean energy measured by calorimetry) over the time interval. If successful, this experiment would, in the opinion of the authors, be the first laboratory experiment to directly verify the equivalency of mass and energy. 4 refs., 2 figs., 3 tabs

PURPOSE: While there has been systematic research on the experiences of immigrant patients in mental health services within certain European countries, little research has explored the experiences of mental health professionals in the delivery of services to immigrants across Europe. This study...... sought to explore professionals' experiences of delivering care to immigrants in districts densely populated with immigrants across Europe. METHODS: Forty-eight semi-structured interviews were conducted with mental health care professionals working in 16 European countries. Professionals in each country...... were recruited from three areas with the highest proportion of immigrants. For the purpose of this study, immigrants were defined as first-generation immigrants born outside the country of current residence, including regular immigrants, irregular immigrants, asylum seekers, refugees and victims...

Angelini, A.; Coppi, B.; Nassi, M.

1992-01-01

This paper reports on high magnetic field experiments which can be designed to investigate D-T ignition conditions based on present-day experimental results and theoretical understanding of plasma phenomena. The key machine elements are: large plasma currents, compact dimensions, tight aspect ratios, moderate elongations and significant triangularities of the plasma column. High plasma densities, strong ohmic heating, the needed degree of energy confinement, good plasma purity and robust stability against ideal and resistive instabilities can be achieved simultaneously. The Ignitor design incorporates all these characteristics and involves magnet technology developments, started with the Alcator experiment, that use cryogenically cooled normal conductors

To accomplish a large-scale experiment, such as large helical device (LHD) experiment, effective cooperation among institutes is necessary. In order to establish such cooperation, the NIFS provides the following remote participation facilities for the LHD experiments. (1) Remote access: The user can use a virtual private network (VPN) to connect to the LAN. This is the most flexible technique to participate in the experiments. The users who are not familiar with the experiments can log into the remote server running MetaFrame and Linux. In these computers, the required software is already installed. Therefore, the user need not be concerned with installing software. (2) Remote data reference: A mirror server exists to provide physical data to remote users. Moreover, the users can retrieve summarized data via a web server, which provides summarized information of each discharge experiment and graphs of the principal physical data. These graphs are useful for finding the required data quickly. (3) Remote communication and monitoring: For effective remote cooperation, communication between researchers is very important. For this purpose, a video conferencing system and a video streaming service are available. In addition to these facilities, the NIFS introduced Super SINET in 2002. This is an optical-fiber-based network. The backbone speed of this network is 10 Gbps, and the speed is 1 Gbps for direct connections

Heating experiments of JT-60

International Nuclear Information System (INIS)

1987-01-01

In JT-60, after the finish of the first stage Joule experiment, the heating facilities were installed, and the heating experiment was started in August, 1986. As to neutral beam injection, the beam injection experiment at the maximum rating 20 MW carried out, and also as to RF, the injection experiment up to 1.4 MW was carried out in both ion cyclotron and low band hybrid waves. The results worthy of special mention in the heating experiment were the success in the current drive up to 1.7 MA at maximum using low band hybrid waves and the improvement of plasma confinement characteristics obtained by the compound heating of NBI and RF. In this paper, the main results of these heating experiments and their significance are explained. The JT-60 is the testing facilities for attaining the critical plasma condition by additionally heating the plasma which is generated by Joule electric discharge with NBI and RF heatings. The experimental operation cycle of the JT-60 consists of the unit cycle of two weeks, and the number of days in operation is nine days. The temperature of heated plasma rose to 70 million deg C in the 20 MW NBI heating. Hereafter, the improvement of confinement time by increasing the stored energy of plasma is attempted. (Kako, I.)

Out-of-body experiences associated with seizures

Full Text Available Alterations of consciousness are critical factors in the diagnosis of epileptic seizures. With these alterations in consciousness, some persons report sensations of separating from the physical body, experiences that may in rare cases resemble spontaneous out-of-body experiences. This study was designed to identify and characterize these out-of-body-like subjective experiences associated with seizure activity. 55% of the patients in this study recalled some subjective experience in association with their seizures. Among our sample of 100 patients, 7 reported out-of-body experiences associated with their seizures. We found no differentiating traits that were associated with patients’ reports of out-of-body experiences, in terms of either demographics; medical history, including age of onset and duration of seizure disorder, and seizure frequency; seizure characteristics, including localization, lateralization, etiology, and type of seizure, and epilepsy syndrome; or ability to recall any subjective experiences associated with their seizures. Reporting out-of-body experiences in association with seizures did not affect epilepsy-related quality of life. It should be noted that even in those patients who report out-of-body experiences, such sensations are extremely rare events that do not occur routinely with their seizures. Most patients who reported out-of-body experiences described one or two experiences that occurred an indeterminate number of years ago, which precludes the possibility of associating the experience with the particular characteristics of that one seizure or with medications taken or other conditions at the time.

Intuitive Experiences from Sohrevardi’s Viewpoint

Directory of Open Access Journals (Sweden)

Reza Heydarinoori

2012-05-01

Full Text Available The truth of intuitive experiences and how to fulfill them are among the issues that all people, cultures and rituals have faced with and expressed views about. There are two major approaches the essence-oriented notion which has emphasized on the cohesion and commonality of these experiences between individuals and people, and construction-oriented perspective which has considered more important roles for the discovery ideas and thoughts in the development and shaping of these experiences, so there are essential differences of them between people and cultures. Intellectual system of Illumination, which has been developed according to Sohrevardi’s discussions, has unique and valuable view in this regard. It asserts that :::::union::::: with light underlies mystical revelation and the specific self-centeredness is involved in the realization of these experiences along with illumination, observation, :::::union:::::, and inexistence. Although characteristics of illumination and talent are essential in this system of thought, the collection of features regarding spiritual experiences, according to Sohrevardi, represents a kind of essence-orientation in mystical revelation. The personal unity of experiences based on the thinking of each individual does not mean to separate experiences. Rather, they all have common grounds. The present study first, refers to the views expressed in this regard, and then explains what and how of spiritual experiences from the viewpoint of Sohrevardi. It finally, provides answers to some unknown issues.

This paper describes the key findings of a two year project focused on children's experiences of domestic violence. It draws on 107 interviews with children in Greece, Italy, Spain and the UK. The paper explores children's capacity to articulate their experiences, and highlights that they are not 'witnesses' to intimate partner violence, but experience it directly and make meaning of it, as members of a family affected by violence. I argue that children need to be recognised as direct victims...

We have conducted an extensive series of experiments on the Nova laser to measure hydrodynamic instabilities in planar foils accelerated by x-ray ablation. Single mode experiments allow a measurement of the fundamental growth rates from the linear well into the nonlinear regime; multimode foils allow an assessment of the degree of mode coupling; and surface-finish experiments allow a measurement of the evolution of a broad spectrum of random initial modes. Experimental results and comparisons with theory and simulations are presented

The REXUS/BEXUS is a programme realized under a bilateral agency agreement between the German Aerospace Centre (DLR) and the Swedish National Space Board (SNSB) (Source: www.rexusbexus.net) . Within this programme, the experiment proposed by LOW Gravity was given the opportunity to fly on board of REXUS 16 from Kiruna, Sweden, in May 2014. Since space settlements are within our reach and material processing in reduced gravity is a key requirement, we aim to improve this field by investigating the melting and welding processes taking place in milligravity on board of a sounding rocket. Our main objective is to analyze the surface deformation and physical properties of titanium and acid core solder alloys welded/melted under miligravity conditions with a 25W LASER diode. The main components of our experiment are the metal samples, the LASER diode and the control electronics. The metal samples are placed in front of an optical system and are shifted during approximately 120 seconds of milligravity. The optical system is connected via an optic fiber to the LASER diode. The electronics consists of two custom-made boards: the mainboard which is connected to the REXUS interface and controls the LASER diode and the sample shifting and the logboard which has an SD card to log all experiment data (sample position, experiment acceleration and rotation rate, pressure and temperature, battery voltage and LASER diode status). During the flight, due to unexpected vibration levels, the fiber optics was damaged at T+70 and the experiment could not fulfill its main objective. A GoPro camera mounted inside the experiment box recorded the experiment operation. Valuable information regarding temperature and battery voltage was also sent remotely to our Ground Station. This data enabled us to perform a thorough failure analysis. Parallel readings of these parameters taken by other experiments and by the REXUS Service Module corroborate our data and increase the accuracy of our analysis

A pre-flight test experiment of a microwave-ionosphere nonlinear interaction rocket experiment (MINIX) has been carried out in a space plasma simulation chamber. Though the first rocket experiment ended up in failure because of a high voltage trouble, interesting results are observed in the pre-flight experiment. A significant microwave heating of plasma up to 300% temperature increase is observed. Strong excitations of plasma waves by the transmitted microwaves in the VLF and HF range are observed as well. These microwave effects may have to be taken into account in solar power satellite projects in the future.

This report on solar neutrino experiments will include a summary of the results of the chlorine detector, and an account of our plans to build a gallium solar neutrino experiment. In addition to discussing the experimental side of the solar neutrino problem I would like to relate our experiences during the last 15 years in working in the Homestake Gold Mine. In the course of our work at Homestake a number of independent groups have asked to use our facilities and, because of the cooperative and helpful attitude of the Mine management, these experimentalists could be easily accommodated. A brief account of these experiences may be useful for the main business of this workshop, building large particle detectors for observing nucleon decay, and the related question of the need for a national underground physics facility

The Swedish astrophysicist and Nobel Prize winner Hannes Alfven said: Theories come and go - the experiment is here forever. Often a theory, which we set up to describe an observed physical phenomenon, suffers from the lack of knowledge of decisive parameters, and therefore at best the theory...... becomes insufficient. Contrary, the experiment always reveals nature itself, though at prevailing experimental conditions. With essential parameters being out of control and even maybe unidentified, apparently similar experiments may deviate way beyond our expectations. However, these discrepancies offer...... us a chance to reflect on the character of the unknown parameters. In this way non-concordant experimental results may hold the key to the development of better theories - and to new experiments for the testing of their validity. Cavitation and cavitation nuclei are phenomena of that character....

Integrating the philosophy and psychology of aesthetic experience: development of the aesthetic experience scale.

Science.gov (United States)

Stamatopoulou, Despina

2004-10-01

This study assessed the dynamic relationship between person and object in aesthetic experience. Patterns of the structure of aesthetic experience were derived from a conceptual model based on philosophical and psychological ideas. These patterns were further informed by interviewing individuals with extensive involvement in aesthetic activities and 25 secondary students. Accordingly, patterns were tested by developing a large pool of items attempting to identify measurable structural components of aesthetic experience. Refined first in a pilot study, the 36-item questionnaire was administered to 652 Greek students, aged from 13 to 15 years. Correlation matrices and exploratory factor analyses on principal components were used to examine internal structural relationships. The obliquely rotated five-factor solution of the refined instrument accounted for the 44.1% of the total variance and was combatible with the conceptual model of aesthetic experience, indicating the plausibility of both. The internal consistency of the items was adequate and external correlational analysis offered preliminary support for subsequent development of a self-report measure that serves to operationalize the major constructs of aesthetic experience in the general adolescent population. The results also raise theoretical issues for those interested in empirical aesthetics, suggesting that in experiential functioning, expressive perception and affect may play a more constructive role in cognitive processes than is generally acknowledged.

Effects of Emotional Experience in Lexical Decision

Full Text Available Previous research has examined the effects of emotional experience (i.e., the ease with which words evoke emotion information in semantic categorization, word naming, and Stroop tasks (Moffat, Siakaluk, Sidhu, & Pexman, 2015; Newcombe, Campbell, Siakaluk, & Pexman, 2012; Siakaluk, Knol, & Pexman, 2014. However, to date there are no published reports on whether emotional experience influences performance in the lexical decision task (LDT. In the present study, we examined the influence of emotional experience in LDT using three different stimulus sets. In Experiment 1 we used a stimulus set used by both Kousta, Vinson, and Vigliocco (2009; Experiment 1 and Yap and Seow (2014 that is comprised of 40 negative, 40 positive, and 40 neutral words; in Experiment 2 we used a stimulus set comprised of 150 abstract nouns; and in Experiment 3 we used a stimulus set comprised of 373 verbs. We observed facilitatory effects of emotional experience in each of the three experiments, such that words with higher emotional experience ratings were associated with faster response latencies. These results are important because the influence of emotional experience: (a is observed in stimulus sets comprised of different types of words, demonstrating the generalizability of the effect in LDT; (b accounts for LDT response latency variability above and beyond the influences of valence and arousal, and is thus a robust dimension of conceptual knowledge; (c suggests that a richer representation of emotional experience provides more reliable evidence that a stimulus is a word, which facilitates responding in LDT; and (d is consistent with grounded cognition frameworks that propose that emotion information may be grounded in bodily experience with the world (Barsalou, 2003, 2009; Vigliocco, Meteyard, Andrews, & Kousta, 2009.

Volatile Removal Assembly Flight Experiment and KC-135 Packed Bed Experiment: Results and Lessons Learned

Holder, Donald W.; Parker, David

2000-01-01

The Volatile Removal Assembly (VRA) is a high temperature catalytic oxidation process that will be used as the final treatment for recycled water aboard the International Space Station (ISS). The multiphase nature of the process had raised concerns as to the performance of the VRA in a microgravity environment. To address these concerns, two experiments were designed. The VRA Flight Experiment (VRAFE) was designed to test a full size VRA under controlled conditions in microgravity aboard the SPACEHAB module and in a 1 -g environment and compare the performance results. The second experiment relied on visualization of two-phase flow through small column packed beds and was designed to fly aboard NASA's microgravity test bed plane (KC-135). The objective of the KC-135 experiment was to understand the two-phase fluid flow distribution in a packed bed in microgravity. On Space Transportation System (STS) flight 96 (May 1999), the VRA FE was successfully operated and in June 1999 the KC-135 packed bed testing was completed. This paper provides an overview of the experiments and a summary of the results and findings.

The main objective of DIRAC experiment is the measurement of the lifetime {tau} of the exotic hadronic atom consisting of {pi}{sup +} and {pi}{sup -} mesons. The lifetime of this atom is determined by the decay mode {pi}{sup +} {pi}{sup -} {yields} {pi}{sup 0} {pi}{sup 0} due to the strong interaction. Through the precise relationship between the lifetime and the S-wave pion-pion scattering length difference |a{sub 0} - a{sub 2}| for isospin 0 and 2 (respectively), a measurement of {tau} with an accuracy of 10% will allow a determination of |a{sub 0} - a{sub 2}| at a 5% precision level. Pion-pion scattering lengths have been calculated in the framework of chiral perturbation theory with an accuracy below 5%. In this way DIRAC experiment will provide a crucial test of the chiral symmetry breaking scheme in QCD effective theories at low energies.

We performed experiments at the Omega Laser Facility to characterize the initial, laser-driven state of a radiative shock experiment. These experiments aimed to measure the shock breakout time from a thin, laser-irradiated Be disk. The data are then used to inform a range of valid model parameters, such as electron flux limiter and polytropic γ, used when simulating radiative shock experiments using radiation hydrodynamics codes. The characterization experiment and the radiative shock experiment use a laser irradiance of ∼7 × 10 14 W cm −2 to launch a shock in the Be disk. A velocity interferometer and a streaked optical pyrometer were used to infer the amount of time for the shock to move through the Be disk. The experimental results were compared with simulation results from the Hyades code, which can be used to model the initial conditions of a radiative shock system using the CRASH code

SIMULATED ANIMAL EXPERIMENTS IN TEACHING AND RESEARCH

Full Text Available Animal experiments are of paramount importance in the pre-clinical screening of new chemical entity. On the other hand, various regulatory guidelines for animal experiments are becoming more stringent in the face of worldwide protests by animal rights activists. Moreover, simulated animal experiments’ softwares are being developed and they can be implemented in the postgraduate and graduate students’ curriculum for demonstration of standard physiological and pharmacological principles compared to real time animal experiments. In fact, implementation of virtual experiment will decrease hand on experience of animal experiments among medical students, but after medical graduation, animal experiment is lest utilized during their day to day clinical practice. Similarly, in case of postgraduate pharmacology curriculum, computer based virtual animal experiments can facilitate teaching and learning in a short span of time with various protocols, without sacrificing any animal for already established experimental outcomes.

The AEGIS experiment 1 (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is planned to perform the first measurement of the gravitational acceleration on antimatter by observing the free fall of antihydrogen atoms. By combining techniques based on recent developments in the production of positronium and its laser excitation to Rydberg states, such a study seems indeed to be feasible for neutral antimatter. We present here some of the experimental techniques involved in the experiment as well as the status of the detector test envisioned for the gravity measurement.

Sexual experiences in childhood: young adults' recollections.

Science.gov (United States)

Larsson, IngBeth; Svedin, Carl-Göran

2002-06-01

Childhood sexuality and children's sexual experiences have become increasingly important to study because our knowledge on the impact of sexually abusive experiences on children's developing sexuality has increased. The main aim of this paper was to study aspects of young adults' recollections of their sexual experiences before the age of 13, solitary and shared, mutual as well as coercive. Anonymous questionnaires were answered by 269 final year, senior high-school students, mean age 18.6 years; 82.9% of the students reported solitary sexual experiences and 82.5% had mutual experiences together with another child. Most of the children had their experiences together with a same-age friend. Girls had more same-sex experiences than boys did. Thirteen percent reported coercive experiences where they had been tricked, bribed, threatened, or physically forced into participation. Some children, 8.2%, had coerced another child into participation in sexual activities. The majority thought of their childhood experiences as normal. There were also 6.3% of the respondents who had had inappropriate sexual experiences with someone at least 5 years older, the majority being girls. Gender differences were evident in several respects: girls were more often coerced, they felt more guilt, and they had far less experience of masturbation, whereas boys were somewhat more active in explorative activities on their own as well as with peers. Some kind of coercive sexual experiences appears to be part of growing up for quite a few children, although in general the years before puberty seem to be years of frequent mutual sexual exploration and experimentation.

Qualitative experiments in psychology

DEFF Research Database (Denmark)

Wagoner, Brady

2015-01-01

In this article, I explore the meaning of experiments in early twentieth century psychology, focusing on the qualitative experimental methodology of psychologist Frederic BARTLETT. I begin by contextualizing BARTLETT's experiments within the continental research tradition of his time, which...... was in a state of transition from a focus on elements (the concern of psychophysics) to a focus on wholes (the concern of Gestalt psychology). The defining feature of BARTLETT's early experiments is his holistic treatment of human responses, in which the basic unit of analysis is the active person relating...... to some material within the constraints of a social and material context. This manifests itself in a number of methodological principles that contrast with contemporary understandings of experimentation in psychology. The contrast is further explored by reviewing the history of "replications...

This paper discusses how front-line employees can play an important role in innovation processes that lead tourism companies from service production to experience creation. The increasing focus on experiential value by customers in general (Sundbo and Sørensen, 2013) puts pressure on service...... companies to move from functional service production to creating experiences (Pine and Gilmore, 2013). This is also the case in tourism companies. In tourism, most encounters between employees and tourists operate on a service logic (Sørensen and Jensen, 2015). Thus, we suggest there is a value potential...... in developing such encounters into experience encounters focusing on the co-creation of experiential value. While frontline employees are central for service quality they are mostly not included in systematised innovation processes in tourism companies.

Paranormal experiences in the general population.

Science.gov (United States)

Ross, C A; Joshi, S

1992-06-01

The Dissociative Disorders Interview Schedule was administered to a random sample of 502 adults in the general population of Winnipeg, a midwestern Canadian city. Results showed that paranormal/extrasensory experiences were common in the general population. They were linked to a history of childhood trauma and to other dissociative symptom clusters. A factor analysis of the paranormal experiences identified three factors which together accounted for 44.0% of the combined variance of the scores. A model is proposed in which paranormal experiences are conceptualized as an aspect of normal dissociation. Like dissociation in general, paranormal experiences can be triggered by trauma, especially childhood physical or sexual abuse. Such experiences discriminate individuals with childhood trauma histories from those without at high levels of significance.

Transformations of emotional experience.

Science.gov (United States)

de Cortiñas, Lia Pistiner

2013-06-01

In this paper the author approaches mental pain and the problems in a psychoanalytic treatment of patients with difficulties in the psychic transformation of their emotional experiences. The author is interested in the symbolic failure related to the obstruction of development of phantasies, dreams, dream-thoughts, etc. She differentiates symbolization disturbances related to hypertrophic projective identification from a detention of these primitive communications and emotional isolation. She puts forward the conjecture that one factor in the arrest of this development is the detention of projective identifications and that, when this primitive means of communication is re-established in a container-contained relationship of mutual benefit, this initiates the development of a symbolization process that can replace the pathological 'protection'. Another hypothesis she develops is that of inaccessible caesuras that, associated with the detention of projective identification, obstruct any integrative or interactive movement. This caesura and the detention of projective identifications affect mental functions needed for dealing with mental pain. The personality is left with precarious mental equipment for transforming emotional experiences. How can a psychoanalytical process stimulate the development of creative symbolization, transforming the emotional experiences and leading towards mental growth? The author approaches the clinical problem with the metaphor of the psychic birth of emotional experience. The modulation of mental pain in a container-contained relationship is a central problem for the development of the human mind. For discovering and giving a meaning to emotional experience, the infant depends on reverie, a function necessary in order to develop an evolved consciousness capable of being aware, which is different from the rudimentary consciousness that perceives but does not understand. The development of mature mental equipment is associated with the

Experience and lessons learned in the assessment of safety justifications for experiments mounted in research reactors

International Nuclear Information System (INIS)

Cox, R.F.

1990-01-01

Some experiments in research reactors are arguably a risky undertaking due to their uncertain outcome. The justifications for such experiments require careful assessment to validate their undertaking. The public, the operators and the installation itself must be safeguarded. Assessment of the potential risk is an acquired skill but in doing so the route can be eased by learning from the lessons experience can teach. This paper, essentially for the usage of safety managers, sets out some of the issues relating to the assessment process gained from our experience over a few tens of years in the assessment of experiments. Many of the conclusions reached may appear all too obvious viewed in retrospect, but they were not necessarily clear at the time. Those organizations setting up assessment teams may find some of the conclusions of value such that their proposed management system can embrace methodologies for assessment that can avoid or lessen the impact of some of the pitfalls we have tried to identify. Failure to recognise some of these points may run the risk of delayed clearances, dilated timescales and cost overruns. It is in the hope of reducing all these penalties that we offer our experiences

Sustained Spheromak Physics Experiment, SSPX

International Nuclear Information System (INIS)

Hooper, E.B.

1997-01-01

The Sustained Spheromak Physics Experiment is proposed for experimental studies of spheromak confinement issues in a controlled way: in steady state relative to the confinement timescale and at low collisionality. Experiments in a flux - conserver will provide data on transport in the presence of resistive modes in shear-stabilized systems and establish operating regimes which pave the way for true steady-state experiments with the equilibrium field supplied by external coils. The proposal is based on analysis of past experiments, including the achievement of T e = 400 eV in a decaying spheromak in CTX. Electrostatic helicity injection from a coaxial ''''gun'''' into a shaped flux conserver will form and sustain the plasma for several milliseconds. The flux conserver minimizes fluxline intersection with the walls and provides MHD stability. Improvements from previous experiments include modem wall conditioning (especially boronization), a divertor for density and impurity control, and a bias magnetic flux for configurational flexibility. The bias flux will provide innovative experimental opportunities, including testing helicity drive on the large-radius plasma boundary. Diagnostics include Thomson scattering for T e measurements and ultra-short pulse reflectrometry to measure density and magnetic field profiles and turbulence. We expect to operate at T e of several hundred eV, allowing improved understanding of energy and current transport due to resistive MHD turbulence during sustained operation. This will provide an exciting advance in spheromak physics and a firm basis for future experiments in the fusion regime

Adoption of Mobile Apps: The Role of Experience

Directory of Open Access Journals (Sweden)

Harryadin Mahardika

2012-12-01

Full Text Available The form of initial experience with mobile application determines consumers’ likelihood to adopt it. This paper examines the effects of two forms of experience (direct versus indirect toward the formation of consumers behavioral intentions (versus behavioral expectations to adopt mobile applications. A direct experience induces concrete mental process that underlies the formation of behavioral expectations, whereas an indirect experience induces abstract mental process that underlies the formation of behavioral intentions. Results from Experiment 1 show significant increase in behavioral expectations’ predictive ability when subjects engaged in a direct experience than an indirect experience. Meanwhile, the effects of a direct experience were subtle toward behavioral intentions’ predictive ability. In Experiment 2, the intensity of direct experience revealed additional caveats on the predictive ability of behavioral intentions and behavioral expectations. It is found that higher intensity of a direct experience has a stronger effect toward behavioral expectations than behavioral intentions. Findings of these experiments could be used as a ground to design an intervention strategy for mobile applications pre-adoption experience.

Fuel reliability experience in Finland

International Nuclear Information System (INIS)

Kekkonen, L.

2015-01-01

Four nuclear reactors have operated in Finland now for 35-38 years. The two VVER-440 units at Loviisa Nuclear Power Plant are operated by Fortum and two BWR’s in Olkiluoto are operated by Teollisuuden Voima Oyj (TVO). The fuel reliability experience of the four reactors operating currently in Finland has been very good and the fuel failure rates have been very low. Systematic inspection of spent fuel assemblies, and especially all failed assemblies, is a good practice that is employed in Finland in order to improve fuel reliability and operational safety. Investigation of the root cause of fuel failures is important in developing ways to prevent similar failures in the future. The operational and fuel reliability experience at the Loviisa Nuclear Power Plant has been reported also earlier in the international seminars on WWER Fuel Performance, Modelling and Experimental Support. In this paper the information on fuel reliability experience at Loviisa NPP is updated and also a short summary of the fuel reliability experience at Olkiluoto NPP is given. Keywords: VVER-440, fuel reliability, operational experience, poolside inspections, fuel failure identification. (author)

Millisecond-period meltdown experiments on prompt-burst effects and molten-tin-water dropping experiments

1976-01-01

The U.S. Nuclear Regulatory Commission has initiated a program of confirmatory research for the safety assessment of LMFBR plants. In the sodium-fuel interactions area, this research includes a series of real-time in-pile experiments on the pressure and work potential of prompt-burst excursions as well as laboratory dropping experiments with molten tin and water. The in-pile experiments are performed by Sandia Laboratories in the Annular Core Pulse Reactor (ACPR), which has a minimum period of 1.3 milliseconds. These single-pin experiments are performed in a piston-loaded, stagnent-sodium autoclave, that is conceptually similar to the one used in the S-11 TREAT test. Unlike the S-11 test, however, realistic radial temperature profiles are obtained in the fuel, the cladding, and the sodium by pre-pulsing the reactor about 1/2 second before the main pulse. A series of preparatory runs have been made with helium-filled capsules and at low energy with sodium-filled capsules. The first significant fuel-coolant interaction run is scheduled for late March 1976. This will be a double-pulsed run at 2700 j/gm UO 2 . A continuing series of experiments is planned with oxide and advanced fuels in both fresh and irradiated form. In molten-tin-water dropping experiments at UCLA, microsecond duration multi-flash photography has been used for event diagnostics. Transition or nucleate boiling was found to trigger energetic interactions or vapor explosions. Temperature stratification in the water was found to reduce the threshold tin temperature necessary to produce vapor explosions below that the predicted by the coolant homogeneous nucleation hypothesis. Interaction zone growth times of a few msec. were measured. (auth.)

1990-12-01

This report presents the results of engineering scale dust-control experiments relating to contamination control during handling of transuranic waste. These experiments focused on controlling dust during retrieval operations of buried waste where waste and soil are intimately mixed. Sources of dust generation during retrieval operations include digging, dumping, and vehicle traffic. Because contaminants are expected to attach to soil particles and move with the generated dust, control of the dust spread may be the key to contamination control. Dust control techniques examined in these experiments include the use of misting systems, soil fixatives, and dust suppression agents. The Dryfog Ultrasonic Misting Head, manufactured by Sonics, Incorporated, and ENTAC, an organic resin derived from tree sap manufactured by ENTAC Corporation, were tested. The results of the experiments include product performance and recommended application methods. 19 figs., 7 refs., 6 tabs

Scaling criteria for rock dynamic experiments

Energy Technology Data Exchange (ETDEWEB)

Crowley, Barbara K [Lawrence Radiation Laboratory, University of California, Livermore, CA (United States)

1970-05-01

A set of necessary conditions for performing scaled rock dynamics experiments is derived from the conservation equations of continuum mechanics. Performing scaled experiments in two different materials is virtually impossible because of the scaling restrictions imposed by two equations of state. However, performing dynamically scaled experiments in the same material is possible if time and distance use the same scaling factor and if the effects of gravity are insignificant. When gravity becomes significant, dynamic scaling is no longer possible. To illustrate these results, example calculations of megaton and kiloton experiments are considered. (author00.

Transmutation, the procedure of transforming long-lived radioactive isotopes into stable or short-lived, was proposed for reducing the amount of radioactive waste resulting from technological applications of nuclear fission. The Accelerator Driven Systems (ADS) provide the possibility to generate intense neutron spectrum yielding in an effective transmutation of unwanted isotopes. Such experiments are being carried out for the last 10 years in Synchrophasotron / Nuclotron accelerators at the Veksler-Baldin Laboratory of High Energies of the Joint Institute for Nuclear Research in Dubna, Russia. Thick Pb and Pb-U targets, surrounded by moderators, have been irradiated by protons in the energy range of 0.5-7.4 GeV. Neutron fluence measurements have been performed by different techniques of passive detectors (neutron activation detectors, solid state nuclear track detectors). Transmutation of 129I, 237Np, 239Pu was studied. The results of these experiments are presented and discussed.

Russell, Richard A.; Buchan, Robert W.; Gates, Richard M.

1988-01-01

A study was conducted to identify on-orbit integrated facility needs to support in-space technology experiments on the Space Station and associated free flyers. In particular, the first task was to examine the proposed technology development missions (TDMX's) from the model mission set and other proposed experimental facilities, both individually and by theme, to determine how and if the experiments might be combined, what equipment might be shared, what equipment might be used as generic equipment for continued experimentation, and what experiments will conflict with the conduct of other experiments or Space Station operations. Then using these results, to determine on-orbit facility needs to optimize the implementation of technology payloads. Finally, to develop one or more scenarios, design concepts, and outfitting requirements for implementation of onboard technology experiments.

An experiment simulating the behavior of the very large steam bubbles generated at the time of an accident of core collapse was carried out with a warm water tank, and the applicability of the theory of very small bubble disappearance known at present was examined. The bubbles generated in HCDA (hypothetical core disruptive accident) are expected to be very large, containing sodium, fuel, FP gas and so on, and play important role in the mechanism of emitting radioactive substances in the safety analysis of LMFBRs. In this experiment, the degree of subcool of the warm water pool, the initial radii of steam bubbles and the blowoff pressure of steam were taken as the parameters. The radius of the steam bubbles generated in the experiment was about 6.5 cm, and the state of disappearance was different above and below the degree of unsaturation of 10 deg C. Comparing the disappearance curve obtained by the experiment with the theory of disappearance of small bubbles, the experimental values were between inertia-controlled disappearance and heat transfer-controlled disappearance, and this result was able to be explained generally with the model taking the pressure change within steam bubbles into account. The rise of bubbles was also observed. (Kako, I.)

Experiments in mixed reality

Krum, David M.; Sadek, Ramy; Kohli, Luv; Olson, Logan; Bolas, Mark

2010-01-01

As part of the Institute for Creative Technologies and the School of Cinematic Arts at the University of Southern California, the Mixed Reality lab develops technologies and techniques for presenting realistic immersive training experiences. Such experiences typically place users within a complex ecology of social actors, physical objects, and collections of intents, motivations, relationships, and other psychological constructs. Currently, it remains infeasible to completely synthesize the interactivity and sensory signatures of such ecologies. For this reason, the lab advocates mixed reality methods for training and conducts experiments exploring such methods. Currently, the lab focuses on understanding and exploiting the elasticity of human perception with respect to representational differences between real and virtual environments. This paper presents an overview of three projects: techniques for redirected walking, displays for the representation of virtual humans, and audio processing to increase stress.

Based on the present situation and the development of experiment tests in universities, we introduced a reform in tests of genetics experiments. According to the teaching goals and course contents of genetics experiment, the tests of genetics experiments contain four aspects on the performance of students: the adherence to the experimental procedures, the depth of participation in experiment, the quality of experiment report, and the mastery of experiment principles and skills, which account for 10 %, 20 %, 40 % and 30 % in the total scores, respectively. All four aspects were graded quantitatively. This evaluation system has been tested in our experiment teaching. The results suggest that it has an effect on the promotion of teaching in genetics experiments.

Immersion and Gameplay Experience: A Contingency Framework

Directory of Open Access Journals (Sweden)

Daniel Örtqvist

2010-01-01

Full Text Available The nature of the relationship between immersion and gameplay experience is investigated, focusing primarily on the literature related to flow. In particular, this paper proposes that immersion and gameplay experience are conceptually different, but empirically positively related through mechanisms related to flow. Furthermore, this study examines gamers' characteristics to determine the influence between immersion and gameplay experiences. The study involves 48 observations in one game setting. Regression analyses including tests for moderation and simple slope analysis are used to reveal gamers' age, experience, and understanding of the game, which moderate the relationship between immersion and gameplay experience. The results suggest that immersion is more positive for gameplay experience when the gamer lacks experience and understanding of the game as well as when the gamer is relatively older. Implications and recommendations for future research are discussed at length in the paper.

1993-11-01

Ss who reported UFO experiences were divided into those whose experiences were nonintense (e.g., seeing lights and shapes in the sky) and those whose experiences were intense (e.g., seeing and communicating with aliens or missing time). On a battery of objective tests Ss in these 2 groups did not score as more psychopathological, less intelligent, or more fantasy prone and hypnotizable than a community comparison group or a student comparison group. However, Ss in the UFO groups believed more strongly in space alien visitation than did comparison Ss. The UFO experiences of Ss in the intense group were more frequently sleep-related than the experiences of Ss in the nonintense group. Among the combined UFO Ss, intensity of UFO experiences correlated significantly with inventories that assessed proneness toward fantasy and unusual sensory experiences. Implications are discussed.

These heavy metals such as lead and indium in the groundwater are a serious concern for the environment (Environmental Protection Agency from the mining process. The field experiences at the mining process assist in building our students interest in developing sensors to detect heavy metals of concern such as lead and indium simultaneously by a unique electrochemistry technique called Square Wave Anodic Stripping Voltammetry (SWASV. The field experience assists building the students interest in real –world application and what qualities do they want the electrochemical sensor to possess to be successful for real world usage. During the field trip the students are engaged into learning novel instrumentation such as an SEM (Scanning Electron Microscope to study the working electrode sensor developed to understand the sensor surface morphology properties better as well. The integration of industry setting with academia has been a positive experience for our students that has allowed their understanding of real-world science research needs to succeed in an industrial setting of research.

Harmms, G.A.; Davis, F.J.; Ford, J.T.

1995-01-01

The Department of Energy is conducting an ongoing investigation of the consequences of taking fuel burnup into account in the design of spent fuel transportation packages. A series of experiments, collectively called the Spent Fuel Safety Experiment (SFSX), has been devised to provide integral benchmarks for testing computer-generated predictions of spent fuel behavior. A set of experiments is planned in which sections of unirradiated fuel rods are interchanged with similar sections of spent PWR fuel rods in a critical assembly. By determining the critical size of the arrays, one can obtain benchmark data for comparison with criticality safety calculations. The integral reactivity worth of the spent fuel can be assessed by comparing the measured delayed critical fuel loading with and without spent fuel. An analytical effort to model the experiments and anticipate the core loadings required to yield the delayed critical conditions runs in parallel with the experimental effort

LHCb: Self managing experiment resources

CERN Multimedia

Stagni, F

2013-01-01

Within this paper we present an autonomic Computing resources management system used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware addressed such issues. With a renewed Central Information Schema hosting all resources metadata and a Status System ( Resource Status System ) delivering real time informatio...

Plasmon holographic experiments: theoretical framework

International Nuclear Information System (INIS)

Verbeeck, J.; Dyck, D. van; Lichte, H.; Potapov, P.; Schattschneider, P.

2005-01-01

A theoretical framework is described to understand the results of plasmon holography experiments leading to insight in the meaning of the experimental results and pointing out directions for future experiments. The framework is based on the formalism of mutual intensity to describe how coherence is transferred through an optical system. For the inelastic interaction with the object, an expression for the volume plasmon excitations in a free electron gas is used as a model for the behaviour of aluminium. The formalism leads to a clear graphical intuitive tool for understanding the experiments. It becomes evident that the measured coherence is solely related to the angular distribution of the plasmon scattering in the case of bulk plasmons. After describing the framework, the special case of coherence outside a spherical particle is treated and the seemingly controversial idea of a plasmon with a limited coherence length obtained from experiments is clarified

Nakai, Kozi

1989-08-01

The elementary particle experiment using the 12 GeV proton synchrotron in the National Laboratory for High Energy Physics (KEK) develops centering around the large scale experiment on K-meson decay. In this case, the ideal precision physics is pursued, and efforts have been exerted to improve the experimental techniques. At present the experiment on searching for rare K-decay is advancing. Next, the experiment on searching for CP nonconservation process will be begun. However, these experiments are in severe competition with those in BNL and Fermilab which have powerful accelerators, therefore it is desirable to grasp well the development of the international research plans. Therefore, in order to obtain the quideline for the experimental plan using the KEK proton synchrotron hereafter, the workshop on K-decay was held on July 11∼12, 1989. In this workshop, Arisaka (UCLA), Numao (TRIUMF) and Yamanaka (Fermilab) returned from USA and lectured on the present status of the experiment and the future perspective. The impression of the planner of the proton synchrotron experiment plan on the experiments are recorded. (K.I.)

The Functional Measurement Experiment Builder suite: two Java-based programs to generate and run functional measurement experiments.

Science.gov (United States)

Mairesse, Olivier; Hofmans, Joeri; Theuns, Peter

2008-05-01

We propose a free, easy-to-use computer program that does not requires prior knowledge of computer programming to generate and run experiments using textual or pictorial stimuli. Although the FM Experiment Builder suite was initially programmed for building and conducting FM experiments, it can also be applied for non-FM experiments that necessitate randomized, single, or multifactorial designs. The program is highly configurable, allowing multilingual use and a wide range of different response formats. The outputs of the experiments are Microsoft Excel compatible .xls files that allow easy copy-paste of the results into Weiss's FM CalSTAT program (2006) or any other statistical package. Its Java-based structure is compatible with both Windows and Macintosh operating systems, and its compactness (< 1 MB) makes it easily distributable over the Internet.

Quantum entanglement and neutron scattering experiments

International Nuclear Information System (INIS)

Cowley, R A

2003-01-01

It is shown that quantum entanglement in condensed matter can be observed with scattering experiments if the energy resolution of the experiments enables a clear separation between the elastic scattering and the scattering from the excitations in the system. These conditions are not satisfied in recent deep inelastic neutron scattering experiments from hydrogen-containing systems that have been interpreted as showing the existence of quantum entanglement for short times in, for example, water at room temperature. It is shown that the theory put forward to explain these experiments is inconsistent with the first-moment sum rule for the Van Hove scattering function and we suggest that the theory is incorrect. The experiments were performed using the unique EVS spectrometer at ISIS and suggestions are made about how the data and their interpretation should be re-examined
