Tree rings are used to calibrate radiocarbon measurements. Calibration is necessary to account for changes in the global radiocarbon concentration over time. Results of calibration are reported as age ranges calculated by the intercept method or the probability method, which use calibration curves. The internationally agreed calibration curves for the period reaching as far back as BC are those produced by PJ Reimer et al. Calibration curves have a dendro timescale on the x-axis and radiocarbon years on the y-axis. Calibration is not only done before an analysis but also on analytical results as in the case of radiocarbon dating —an analytical method that identifies the age of a material that once formed part of the biosphere by determining its carbon content and tracing its age by its radioactive decay. Carbon is a naturally occurring isotope of the element carbon. Results of carbon dating are reported in radiocarbon years, and calibration is needed to convert radiocarbon years into calendar years. It should be noted that a BP notation is also used in other dating techniques but is defined differently, as in the case of thermoluminescence dating wherein BP is defined as AD It is also worth noting that the half-life used in carbon dating calculations is years, the value worked out by chemist Willard Libby, and not the more accurate value of years, which is known as the Cambridge half-life.

She drives a white one and He drives a silver one. Hers is newer and in good repair. His is battered on both ends, and has bits held onto the body by wire and that special handyman stickum.

Hedge laying If hedges are not maintained and trimmed regularly, gaps tend to form at the base over many years. In essence, hedgelaying consists of cutting most of the way through the stem of each plant near the base, bending it over and interweaving or pleaching it between wooden stakes. This also encourages new growth from the base of each plant.
Originally, the main purpose of hedgelaying was to ensure the hedge remained stock-proof. Some side branches were also removed and used as firewood.

See Article History Tree fern, any of a group of relatively primitive ferns in the order Cyatheales, most of them characterized by ascending trunklike stems and an arborescent treelike habit. Tree ferns are conspicuous plants of humid tropical forests around the world. Species found at lower elevations are often widespread colonizers of disturbed or successional habitats.
A large number of species are restricted to very small ranges on islands or at higher elevations, often in more-mature forests on isolated tropical mountaintops. Tree ferns are primarily members of the families Cyatheaceae five genera and Dicksoniaceae three genera in the division Polypodiophyta. Hypotheses on the classification of tree ferns have evolved as new species and new information on the relationships between genera have been discovered.
In addition to the two main families given above, the tree ferns include a few small peripheral relatives:

Missionary Sex Positions Ahhh, Missionary. Traditionally considered the “default sex position,” Missionary offers lots of advantages to first-timers and people looking for sex that’s more on the vanilla side. However, there are lots of slight variations on it that can amp things up in terms of the pleasure, the intensity and the kink factor — for both partners. Check out these Missionary-inspired versions: Missionary Carlee Ranger The Missionary position man on top, couple facing each other is the most famous and classic of all positions.
The eye contact, the mild male dominance and the angle of penetration make this a popular one, and odds are, the first time you had sex was in Missionary. Start in regular Missionary, and then flatten your torso as much possible, while your partner should arch her legs and put her legs on your butt. What you’re doing here is targeting the clitoris for more direct rubbing and friction. The pressure you put on her clitoris could help her get to orgasm quicker. You should also be staying nice and deep within her in the C.
In other words, this one is more for her pleasure than yours.

Abstract Urban trees experience site-induced stress and this leads to reduced growth and health. A site assessment tool would be useful for urban forest managers to better match species tolerances and site qualities, and to assess the efficacy of soil management actions. Toward this goal, a rapid urban site index RUSI model was created and tested for its ability to predict urban tree performance. The RUSI model is field-based assessment tool that scores 15 parameters in approximately five minutes.
While the RUSI model did not accurately predict mean diameter growth, it was significantly correlated with recent diameter growth. Certain parameters in the RUSI model, such as estimated rooting area, soil structure and aggregate stability appeared to be more important than other parameters, such as growing degree days. Minimal improvements in the RUSI model were achieved by adding soil laboratory analyses. Field assessments in the RUSI model were significantly correlated with similar laboratory analyses.
Future work on the RUSI model will include developing training modules and testing across a wider geographic area with more urban tree species and urban sites. Previous article in issue.

Some schools conclude that karma continued to exist and adhere to the person until it had worked out its consequences. Nirvana is the state that marks the end of this consciousness continuum and the associated karmic cycle of suffering through rebirths and redeaths. These are called the Gati in cycles of re-becoming, Bhavachakra. Hayes , Dharmakirti denied that mental events were a mere byproduct of the body, instead holding that “both mental events and physical events can be seen as effects of the same set of causal conditions.
This means that all mental events must have a previous mental event as part of its causal nexus presumably stretching back before one’s birth. According to Hayes, Dharmakirti holds therefore that “both physical factors and nonphysical factors play a role in the formation of mental events”, if not there would be no difference between sentient beings and inanimate matter. That is, if the mind is not being conditioned by a previous cognitive event, then it cannot arise from inert matter.
Willson notes that this relies on two further assumptions, the first is that any mental continuum must have previous causes, the second is that materialism is false and that mind cannot emerge solely from matter emergentism. Theravada Abhidhamma makes a similar argument. According to the Abhidhamma teacher Nina van Gorkom, physical and mental events dhammas both depend on each other and on previous events of the same category i. In Abhidhamma, the mental event citta which arises at the first moment of life is called the rebirth consciousness or patisandhi-citta.
The patisandhi-citta is the first citta of a new life and thus its cause can only be in the past. Some modern Buddhists have taken this position.
Dawlish news It added that proposals to install Average Speed Cameras on the A South Devon Highway were supported by Devon and Cornwall Police and the Devon and Cornwall Safety Camera Partnership, saying that enforcement would be beneficial in reducing the traffic speeds on the dual carriageway. The locations for the four sites Site 1 – at the start of the 50mph enforcement zone, near Edginswell, to the south of Kingskerswell.
