Geochemistry from DSDP Holes 67-497 and 67-496
No full textMineralogical identification, glass chemistry, and instrumental neutron activation analyses of Quaternary volcanic ash layers from Leg 67 Holes 496, 497, and 499 are used to correlate the drill holes and on-land sources. We have identified two units at Hole 496 that correspond to the 23,000-yr.-old Pinos Altos ash (Samples 496-3-4, 55-57 cm and 496-3-5, 74-76 cm); the 84,000-yr.-old Los Chocoyos ash corresponds with Sample 496-5-4, 134-146 cm, but this latter correlation is less certain

Participant 496 Community Conversations Interview
No full textIn this interview, Participant 496 describes their experience being an essential worker during the COVID-19 pandemic. They share that it has been more difficult to spend time with family because they must work more hours. The participant explains how this has impacted their time to help their children navigate remote learning. The participant shares about the fear they felt when finding out family members contracted COVID-19. They express their wish that politicians had reacted more quickly to the pandemic.New Jersey Department of Healt
IR nr. 496, LETTE FYLLINGER AV SKUMPLAST
No full textIntern rapport nr. 496, LETTE FYLLINGER AV SKUMPLASTSkumplast er for første gang benyttet som lette masser i en vegfylling på rv. 159, Strømsvegen ved V. Flom bru. Vegen ligger her på svært dårlig grunn vegteknisk sett. Man har hatt store problemer med setninger på dette stedet, og det er derfor benyttet skumplast i oppbygning av vegprofilet for å få en tilfredsstillende avlastning av grunnen. Anlegget ble gjort 1 tiden 18/9 - 15/10-1972, og det ble benyttet to typer skumplast; ekspandert polystyren og in- situ skummet polyuretan. Over skumplasten ligger en overbygning på 50 cm tykkelse. - Vegrn er instrumentert med nivellementsbolter, teleskopmåle e og jordtrykkceller og målinger som har pågått siden anlegget var ferdig, vil fortsette så lenge det ansees nødvendig. Prøver av skum plasten-er blitt testet i anleggsperioden og senere, og det vil også i fremtiden bli tatt ut prøver for under søkelse. Erfaringene med bruk av skumplast 8om lette masser i vegbygging må betegnes som positive. Setningene på det aktuelle stedet er redusert, og vegen må sies å ha en til fredsstillende standard, selv om det er målt relativt store nedbøyninger. - Man kan ved fremtidig bruk av skumplast i vegfyllinger, tenke seg alternative løsninger til bruken av polyuretan sett ut fra et både teknisk og Økonomisk synspunkt
Acute Ethanol Administration Rapidly Increases Phosphorylation of Conventional Protein Kinase C in Specific Mammalian Brain Regions in Vivo
Get PDFBackground
Protein kinase C (PKC) is a family of isoenzymes that regulate a variety of functions in the central nervous system including neurotransmitter release, ion channel activity, and cell differentiation. Growing evidence suggests that specific isoforms of PKC influence a variety of behavioral, biochemical, and physiological effects of ethanol in mammals. The purpose of this study was to determine whether acute ethanol exposure alters phosphorylation of conventional PKC isoforms at a threonine 674 (p-cPKC) site in the hydrophobic domain of the kinase, which is required for its catalytic activity.
Methods
Male rats were administered a dose range of ethanol (0, 0.5, 1, or 2 g/kg, intragastric) and brain tissue was removed 10 minutes later for evaluation of changes in p-cPKC expression using immunohistochemistry and Western blot methods.
Results
Immunohistochemical data show that the highest dose of ethanol (2 g/kg) rapidly increases p-cPKC immunoreactivity specifically in the nucleus accumbens (core and shell), lateral septum, and hippocampus (CA3 and dentate gyrus). Western blot analysis further showed that ethanol (2 g/kg) increased p-cPKC expression in the P2 membrane fraction of tissue from the nucleus accumbens and hippocampus. Although p-cPKC was expressed in numerous other brain regions, including the caudate nucleus, amygdala, and cortex, no changes were observed in response to acute ethanol. Total PKC? immunoreactivity was surveyed throughout the brain and showed no change following acute ethanol injection
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
