Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of 14 C it contains begins to decrease as the 14 C undergoes radioactive decay. Measuring the amount of 14 C in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calculate when the animal or plant died. The older a sample is, the less 14 C there is to be detected, and because the half-life of 14 C the period of time after which half of a given sample will have decayed is about 5, years, the oldest dates that can be reliably measured by this process date to approximately 50, years ago, although special preparation methods occasionally permit accurate analysis of older samples. Research has been ongoing since the s to determine what the proportion of 14 C in the atmosphere has been over the past fifty thousand years. The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample’s calendar age. Other corrections must be made to account for the proportion of 14 C in different types of organisms fractionation , and the varying levels of 14 C throughout the biosphere reservoir effects.

When you have a minor emergency or just need medical care fast and easy, ConvenientMD is here to serve you quickly, professionally, and affordably. No appointment needed – just walk in or check-in online to our urgent care clinic in Bangor today!
I have been to the Bangor clinic twice and both times they have been very fast getting me in to see the doctor. That is the most important thing to me because I hate waiting. They were also friendly and professional. I went to the clinic in Bangor, Maine with symptoms of food poisoning and I could barely stand. I was able to check-in online so that by the time I got to the clinic, I could be seen right away.
Everyone was super caring and efficiently gave me the care that I needed. Thank you for being one of the few great urgent cares out there! A nasty cut is not a good way to end the week, but your staff made quick work of what would have been a very long night somewhere else. Courteous, pleasant, and efficient are only a few of the ways we would describe your staff in Bangor.

By Tim Collins For Mailonline. The teaching chart dating from around was discovered in the chemistry department at University of St Andrews in Scotland. Work has been undertaken to authenticate and preserve the large, fragile chart after it was found among old equipment in A periodic table pictured uncovered during a laboratory clear-out is believed to be the oldest in the world.
The teaching chart dating from around was discovered in the chemistry department at St Andrews University. Professor Eric Scerri from the University of California has dated the table to between and Gallium and scandium, discovered in and respectively, are present but germanium, discovered in , is not. Dmitri Mendeleev pictured made his famous disclosure on periodicity in , and the University of St Andrews chart bears an inscription identifying a scientific printer who operated in Vienna between and Professor Eric Scerri from the University of California has dated the St Andrews version of the table pictured to between and Professor David O’Hagan, former head of chemistry at St Andrews, said: ‘The discovery of the world’s oldest classroom periodic table at the University of St Andrews is remarkable.

We describe eleven core elements that constitute the GCLP standards with the objective of filling a gap for laboratory guidance, based on IND sponsor requirements, for conducting laboratory testing using specimens from human clinical trials. These GCLP standards provide guidance on implementing GLP requirements that are critical for laboratory operations, such as performance of protocol-mandated safety assays, peripheral blood mononuclear cell processing and immunological or endpoint assays from biological interventions on IND-registered clinical trials.
The expectation is that compliance with the GCLP standards, monitored annually by external audits, will allow research and development laboratories to maintain data integrity and to provide immunogenicity, safety, and product efficacy data that is repeatable, reliable, auditable and that can be easily reconstructed in a research setting. The GCLP standards were developed with the objective of providing a single, unified document that encompasses IND sponsor requirements to guide the conduct of laboratory testing for human clinical trials.
Examples of these types of tests include protocol-mandated safety assays such as diagnosis of HIV-1 infection, blood processing to obtain high quality specimens routinely [ 5 ], and cellular and serological immunogenicity assays e. The intent of GCLP guidance is that when laboratories adhere to this process, it ensures the quality and integrity of data, allows accurate reconstruction of experiments, monitors data quality and allows comparison of test results regardless of performance location.
To illustrate the need for a single unified GCLP standards document, Table 1 compares major elements of US, UK and other international guidance documents, showing current gaps. The GCLP core elements described in this paper include: organization and personnel; laboratory equipment; testing facility operations; quality control program; verification of performance specifications; records and reports; physical facilities; specimen transport and management; personnel safety; laboratory information systems and quality management.

Disease symptoms, which may appear 2 to 14 days after exposure, include fever, cough, shortness of breath or difficulty breathing, chills, muscle pain, headache, sore throat and new loss of taste or smell. Older residents and people with certain health conditions have a higher risk of developing more serious illness. People without symptoms may spread the virus.

Funding is allocated to projects using short research cycles targeting the most promising ideas. Each of the selected projects pursue their own objectives, while the NGI RIAs provide the programme logic and vision, technical support, coaching and mentoring, to ensure that projects contribute towards a significant advancement of research and innovation in the NGI initiative. The focus is on advanced concepts and technologies that link to relevant use cases and that can have an impact on the market and society over all.
Applications and services that innovate without a research component are not covered by this model. The goal of the Continuous Call is to make the federated infrastructure directly available for the execution of innovative projects from SMEs. The submission for stage 1 requires a very limited-sized proposal for a short-duration experiment.
Luminescence dating is based on quantifying both the radiation dose received by a sample since its zeroing event, and the dose rate which it has experienced.
