The Archaeology Of Gua Tupak From 1,190 B.P. To 170 B.P. In Bau, Sarawak
No full textIn November and December 2007, an archaeological survey was conducted
by the author and a research team from the Centre for Global Archaeological
Research, Universiti Sains Malaysia, Penang with the cooperation of the Sarawak
Museum Department, Kuching in the limestone caves of the Bau area, southwest
Sarawak in order to search for a site for the author’s Master of Arts (MA) study. The
result of the survey determined Gua Tupak to be a highly potential site and
consequently, excavations were carried out at the site in February and March 2008.
The excavations at Gua Tupak yielded valuable archaeological data that could aid in
providing information on the prehistory of the site and the Bau area. The
archaeological data include various types of artefacts such as shell remains, animal
bones, ceramic sherds and stone artefacts. In addition, charcoal and shell samples
were collected for radiocarbon dating, soil samples were collected for palynological
analysis and soil profiles of the excavated trenches were recorded. Results of the
analyses of artefacts and interpretations of the archaeological data recovered from
Gua Tupak suggest that the site was used as a temporary habitation site or shelter
with two main phases of occupation; the Early Phase with a radiocarbon date of
around 1,190 ± 40 B.P., and the Late Phase with radiocarbon dates ranging from 270
± 50 B.P. to 170 ± 40 B.P
Variation in complement component C1 inhibitor in age-related macular degeneration
No full textThis study assessed variation in plasma levels of the complement regulatorC1 inhibitor (C1inh) in patients with age related macular degeneration (AMD) and controls. Plasma from391 AMD cases and 370 controls was assayed by rate nephelometry to determine C1inh protein levels. Protein levels were analysed for relationships with age, gender, smoking, AMD disease status and genetic variation in the SERPING1 gene, which encodes C1inh, using a multivariate analysis. t-Tests show a significant difference in C1inh levels in AMD cases compared with controls (p = 2.340E-6), smokers compared to non-smokers (p = 1.022E-4) and females compared to males (p = 1.661E-7). Multivariate analysis shows that after accounting for gender and smoking AMD status remained significant. Age was included in the model but was not significant. Including genetic variation in the model shows that one significant SNP (rs2649663) 5? of the SERPING1 gene is associated with C1inh levels though this SNP is not associated with AMD. This suggests that genetic variation in the promoter region of the SERPING1 gene may influence expression of the gene.<br/
Agriculture facilitated permanent human occupation of the Tibetan Plateau after 3600 B.P.
No full textOur understanding of when and how humans adapted to living on the Tibetan Plateau at altitudes above 2000 to 3000 meters has been constrained by a paucity of archaeological data. Here we report data sets from the northeastern Tibetan Plateau indicating that the first villages were established only by 5200 calendar years before the present (cal yr B.P.). Using these data, we tested the hypothesis that a novel agropastoral economy facilitated year-round living at higher altitudes since 3600 cal yr B.P. This successful subsistence strategy facilitated the adaptation of farmers-herders to the challenges of global temperature decline during the late Holocene
A Social Insurance Model for Pharmacare: Ontario's Options for a More Sustainable, Cost-Effective Drug Program
No full textWith annual spending of about $4.5 billion dollars in 2010, Canada’s largest drug plan – the Ontario Drug Program (ODB) – will become harder to afford as the babyboomers age and workforce growth slows. A business-as-usual approach to funding the plan, which provides publicly funded drug benefits to every Ontario resident aged 65 an older, presents a bleak prospect and amounts to wilfully passing on an exorbitant bill to future generations. Ontario, like all jurisdictions, faces tough challenges at the intersection of fiscal and health policy. Partial prefunding and benefit-payment reform of the ODB would put a key health program on a stronger and more sustainable footing.The Health Papers, Ontario Drug Program (ODB), Province of Ontario

Stable isotope, fossil coleoptera and pollen stratigraphy in late quaternary sediments from Ontario and New York State
No full textStable oxygen isotope contents of marl deposits and molluscs from lakes and ponds in northern New York State (U.S.A.) and southwestern Ontario (Canada) are remarkably uniform for carbonates formed between about 12,600 yr B.P. and 2000 yr B.P.. This suggests relatively stable climatic conditions with slowly increasing temperatures throughout this time span, an observation already indicated by fossil beetle data; and re-confirmed by additional data presented in this paper. The variations seen in pollen diagrams probably are related to plant colonization, and climatic parameters such as changing humidities.
This contrasts sharply with observations made in Europe where variations in pollen diagrams are paralleled by changing 18O contents in lacustrine marls and molluscs which clearly reflect climatic/temperature changes during late glacial and early postglacial times (13,500–9000 yr B.P.).
13C contents in marls and molluscs are not directly dependent on climatic change but reflect changing environments with varying aquatic and terrestrial carbon contributions

Location Changes of the Pit-Dwellings and Estimation of the Degree of the Tsunami Disaster Rate on Southern Sanriku Coast, Northeast Japan during the Jomon Period(ca 4700-2900 cal B.P.) : Cases of the Akahama-Ⅱ Site of Ootsuchi Bay and the Hamakawamesawada- I Site of Yamada Bay
No full textThe purpose of this study is to reconstruct the changing process of the altitudes over the sea of the pit-dwellings at Akahama-II site of Ootsuchi bay and Hamakawamesawada-I site of Yamada bay on the southern Sanriku coast, northeast Japan during the Jomon period(ca 4700-2900 cal B.P.) , and to estimate the degree of the tsunami disaster rate by using the inundation depth of the tsunami in the case of the 2011 Tohoku-oki earthquake.
The average altitudes of the pit-dwellings were 5.8m in around 4700 cal B.P., 3.7m in around 4600 cal B.P., and 2.5m in around 4200 cal B.P. in Akahama-II site, and were 6.9m in around 4700 cal B.P., 7.4m in around 4600 cal B.P., 6.5m in around 4500 cal B.P., and 1.6m in around 4000 cal B.P. in Hamakawame-sawada-I site.
There is a tendency to believe the inhabited period was older, the altitudes of the pit-dwellings were higher. There is also a possibility that there was not only the relative uplift of the coast in response to the sinking of the sea-level based on the Glacio-hydro Isostatic Adjustment theory, but also the actual elevation of the coast during 4700 cal B.P. and 4000 cal B.P..
On the other hand, the altitudes over the theoretical sea-level of the pit-dwellings around 4000 cal B.P.-4200 cal B.P. were too low for people to live there at both sites. It is necessary for people to live in the pit-dwellings over altitudes of at least 1 m because of the water level at high tide around the studied areas. It is estimated that the coast sank after around 4200 cal B.P..
The author puts forward that pit-dwellings during the Jomon period were hit by a tsunami that was the same level as the 2011 Tohoku-oki earthquake case, it is estimated that almost all of the pit-dwelings would have been affected by the tsunami at Akahama-II site and a few pit-dwellings would have been safe at Hamakawamesawada-I site.departmental bulletin pape
Evaluatie veldmetingen. Open taludbekledingen; bundeling huidige kennis
No full textIn het kader van het onderzoek aan open taludbekledingen zijn een drietal veldmeetmethoden ontwikkeld en toegepast. Daarnaast is het mogelijk het gedrag van een taludbekleding te voorspellen aan de hand van analytische relaties. Het gaat hierbij met name om de belasting op de toplaag ten gevolge van golfbelasting, en om overdrukken onder de toplaag die ontstaan indien de waterstand in de filterlaag een wisselende buitenwaterstand niet kan volgen. De drie meetmethoden zijn gebundeld in drie aparte verslagen, waarin ook de separate meetverslagen zijn te vinden. Dit verslag beoogt een overzicht te geven van de beschikbare methoden om doorlatendheden, lektijd en leklengte te bepalen. De ervaringen en resultaten worden met elkaar vergeleken. Hierdoor kan het toepassingsgebied van de diverse methodes worden aangegeven. Ten slotte volgen praktische aanwijzingen voor het bepalen van de eigenschappen van bestaande taludbekledingen.Steenzettingen - TAW/EN
