Archaeology This is an informative and engaging site from the BBC. There are special sections on excavating human remains and the story of carbon dating as well as archaeology news stories from the BBC. Visit the Stonehenge Dig section for video of the historic Timewatch dig. The Riddle of Human Origins This offering from Yale University is based on a exhibition and explores the history of fossil hunting and fossils themselves. The history section is essentially an essay, but the rest of the site is highly visual and features great up-close photos of bronze age and neanderthal skulls. It also features a helpful thought somewhat-outdated Timeline of Evolution, a video tour of the exhibition and related links and books. The Stone Age section has a quiz to test your survival skills, a description of tools and animals, a discussion of culture and creativity, and more.

Abstract Deep stratigraphic constrains below the Indonesian Lusi mud eruption are currently lacking due to the absence of deep wells and good quality seismic data. A collection of carbonate clasts has been sampled from the Lusi site, active since its birth in These specimens are part of a large variety of lithotypes erupted from the main crater.
The carbonates analysed comprise scleractinian coral and bivalve shell fragments, probably shallow-water in origin, and clasts consisting of planktonic foraminifera-bearing mudstone, from pelagic deposits. Based on biostratigraphy using planktonic foraminifera, one group of samples reveal to belong to the Planktonic Foraminifera Zone M5b, with an age comprised between The discrepancy suggests that this and the other unduly young samples have possibly been contaminated by geological materials with radiogenic Sr isotope composition.
It is common to make at least 2 and often 4 or 5 measurements to estimate gestational age. In most cases, BPD [Biparietal diameter], HC [Head circumference], AC [Abdominal circumference] and FL [Femur length] are used. Since all of these measurements are strongly related to gestational age, it is not usually important how they are combined.

ABCs of Behavior An easy method for remembering the order of behavioral components: An injury that may include a scrape, a scratch, a scuff, a graze or a cut to the individual’s skin. Abscess A collection of pus around an infection. Absorb, absorption When liquids soak into a tissue they are absorbed.
Some medications are delivered into the body by allowing them to soak into the skin or other body tissues.
How to determine age of a Canon lens
Schizo affective disorder is NOT bipolar disorder plus full symptom schizophrenia. Delusions are the big Kahuna. These are false beliefs. Paranoia is a delusion. Thinking there is a camera in the corner of a room recording your every movement is a delusion.
We present a model to predict gestational age from 3D fetal brain ultrasound images. Abstract We propose an automated framework for predicting gestational age GA and neurodevelopmental maturation of a fetus based on 3D ultrasound US brain image appearance. Our method capitalizes on age-related sonographic image patterns in conjunction with clinical measurements to develop, for the first time, a predictive age model which improves on the GA-prediction potential of US images.
The framework benefits from a manifold surface representation of the fetal head which delineates the inner skull boundary and serves as a common coordinate system based on cranial position. This allows for fast and efficient sampling of anatomically-corresponding brain regions to achieve like-for-like structural comparison of different developmental stages. We develop bespoke features which capture neurosonographic patterns in 3D images, and using a regression forest classifier, we characterize structural brain development both spatially and temporally to capture the natural variation existing in a healthy population.

How to determine age of a Canon lens Posted on Feb 10, Have you ever wondered how old is your Canon lens? If you buy a new lens from an authorized dealer, the chances are, the lens was manufactured fairly recently. So if you bought your lens new, you have a good idea how old your lens is. In this quick tutorial I will show you exactly how to decode these date codes on older lenses as well as the new serial numbers.
As I have mentioned above, Canon has been placing date codes on their lenses for a long time and previously many lenses had the date code placed separate from the actual serial number. In , Canon started placing date codes on select lenses only.
Bipolar disorder is strictly a mood disorder, while schizoaffective disorder is a mood disorder combined with separate psychotic symptoms that are not attached to mania or depression.
Attention Deficit Hyperactivity Disorder Medication Prescribing Practice Unlike most other medications, stimulant dosages usually are not weight dependent. Clinicians should begin with a low dose of medication and titrate upward because of the marked individual variability in the dose-response relationship. Clinicians should continue to use higher doses to achieve better responses. This strategy may require reducing the dose when a higher dose produces side effects or no further improvement.
The best dose of medication for a given child is the one that leads to optimal effects with minimal side effects. The dosing schedules vary depending on target outcomes, although no consistent controlled studies compare different dosing schedules. For example, if there is a need for relief of symptoms only during school, a 5-day schedule may be sufficient. By contrast, a need for relief of symptoms at home and school suggests a 7-day schedule.
Children who fail to show positive effects or who experience intolerable side effects on one stimulant medication should be tried on another of the recommended stimulant medications. Children who fail 2 stimulant medications can be tried on a third type or formulation of stimulant medication for the same reason.
The next step would be to review the history and symptoms to confirm the diagnosis. Primary care physicians most likely will consider referral to a child and adolescent psychiatrist at this point. Although there is at least one double blind, randomized controlled trial for bupropion , and TCAs , the evidence base for these medications is far weaker than for the FDA-approved agents. Although the mechanism of action is not known, guanfacine, the active ingredient in INTUNIV, is thought to selectively stimulate alpha-2A adrenoreceptors in the prefrontal cortex.
Prehistory (Origins & Stone Age)
Outside hinge with 3 barrels: Many of the early hinges were replaced, as have been some later ones, so the hinge barrel count is not always absolutely accurate as it is possible a repair replacement has been made. The appearance wasn’t so great and there was a tendency to rust, so a black crackle paint was used on these lighters. Black crackle Zippos were apparently produced only for shipment to armed forces overseas and none were produced for domestic sales.
The difference between a and Zippo can be determined by the insert as the ones had markings on them. The information presented here came from researching a number of Internet sites with bits and pieces from each.
Clear physical evidence of the existence of the Little Ice Age and theMedieval Warm Period. Claims to the contrary are false.
Ultrasonic Fetal Measurement Standards If we assume a fetus is growing normally, biometric measurements are determined by gestational age, and we can estimate the gestational age and thus the due date. Conditions which alter fetal growth will make the estimates less reliable. Although many embryonic and fetal structures can be measured, only a few measurements are easy and repeatable enough for widespread use.
The most common are: The first element to be measurable is the gestation sac of the early pregnancy. The gestational sac is measured in three dimensions, and the average, the Mean Sac Diameter MSD used for estimating gestational age. The length of the embryo on the longest axis excluding the yolk sac constitutes the crown-rump length.
The transverse width of the head at it’s widest. We measure from the the leading edge to leading edge of the bones, because this leading interface is most distinct. Since the head is oval, the error induced by small errors in positioning is small, making for a repeatable, robust measure. The BPD best used after 12 weeks. The femur length is a repeatable measurement with accuracy similar to the BPD. It is effected by skeletal dysplasias, but since these are rare, it is a reliable measurement which confirms measurements of the head.

Daly “Whan that Aprille with his shoures soote – The droughte of March hath perced to the roote, And bathed every veyne in swich licour Of which vertu ungendred is the flour;” – from The Canterbury Tales, by Geoffrey Chaucer, “Our years are turned upside down; our summers are no summers; our harvests are no harvests! In their previous report , the IPCC illustrated their, then, understanding of how global climate had changed, not just during the previous 95 years, but also the past 1, years.
In so doing they presented this graph Fig 1. Historical records from all over Europe, and Greenland attest to the reality of both events, and their profound impact on human society. For example, the colonisation of Greenland by the Vikings early in the millennium was only possible because of the medieval warmth. This is because we have direct observations of sunspot counts going back to AD, which allows us to compare variations in the sun with variations to global climate.
But even before when the Maunder Minimum started, the cycle was clearly fragmented and irregular in contrast with the solid rhythmic cycles of subsequent years after When we compare this extraordinary solar event with the climate record from Fig. The inference is clear. This account of climatic history contains two serious difficulties for the present global warming theory. Both propositions posed a serious threat to continued public acceptance of the climate modeller’s catastrophic view of future climate.
This is because new findings in solar science suggested that the sun, not greenhouse gases, were the primary driver of 20th century climate trends. The power of the sun to modulate our climate has been reinforced by a large body of recent research that shows it is not only the cyclic warming and cooling of the sun manifested by the year sunspot cycle causing our climate to change, but also changes in the solar spectrum towards greater ultra-violet radiation compared with visible or infra-red light see Fig.
