Description:
While Olivella beads are a common component of archaeological sites in California, and were widely traded in prehistory, no method has been developed to trace individual beads to a point of origin. This study examines the potential of stable carbon and oxygen isotopes to source Olivella beads from the Pacific coast. The study shows that 1) the oxygen isotopic composition of modern Olivella biplicata shells faithfully varies with ambient sea surface temperature and local upwelling, lending themselves to sourcing studies; 2) oxygen isotope ratios in modern shells can be used to identify shells that grow north versus south of Point Conception, California; and 3) shell carbon isotope ratios may further subdivide these two regions into more spatially restricted source zones. Analyses on a small sample of 10 beads found at various archaeological sites within the interior of California suggest that all were made in southern California. ... Read more

Description:
The new theory of democratic phase coherent data-scatter (DPCD-S) is introduced. Basics of UV-visible spectrometry theory and error propagation have been presented. The qualitative spectral analysis provided is point-by-point over the complete data set and not just limited to Lambda-maxima. Equal weightings of the 'voting' data scattering algorithm are employed in the analysis of both the calibration and food colour data and this is consequently the democratic algorithm. The paper shows how the technique can be used with UV-visible standards to analyse the wavelength and photometric calibration of a spectrophotometer. The main results relate to the analysis of a series of spectra taken on complex mixtures of three important food dyes and their quantitative analysis using the phase coherent data-scatter technique. This method is shown to offer new possibilities for identifying and archiving UV-visible spectra from a single point in a transform space. Complex spectra can therefore be represented by a single point in this transform space, which is weighted by the 'votes' of all the data points in the complex data set. The software allows the user to interrogate the scatter results and locate the scatter point to the specific spectral positions. A new mathematical operator has been introduced to resolve any possible coincidence of two spectral projection points. Analysis of two close spectra from very-different admixtures of food colours shows powerfully the utility of this operator. Error propagation severely limits the accuracy of the usual UV-method of simultaneous equation secondary mixtures analysis. ... Read more

From the supplier: Biocode has developed a special rapid immunoassay technology for fingerprinting food products. The process involves introduction of an inert chemical substance or marker to the product and observing antibody reaction to determine product quality. The technique detects possible product counterfeiting and subsidy fraud. In addition, the marking system is also projected for potential use in process control and contaminated food containment.

Product Description
Brain Fingerprinting is a controversial forensic science technique that determines whether specific information is stored in a subject´s brain by measuring electrical brainwave responses to words, phrases, or pictures that are presented on a computer screen. Brain fingerprinting was invented by Lawrence Farwell. The theory is that the brain processes known, relevant information differently from the way it processes unknown or irrelevant information. The brain´s processing of known information, such as the details of a crime stored in the brain, is revealed by a specific pattern in the EEG. Farwell´s brain fingerprinting originally used the well known P300 brain response to detect the brain´s recognition of the known information. Later Farwell discovered the MERMER, which includes the P300 and additional features and is reported to provide a higher level of accuracy than the P300 alone. ... Read more

Product Description
High Quality Content by WIKIPEDIA articles! Radio fingerprinting is a process that identifies a cellular phone or any other radio transmitter by the unique "fingerprint" that characterizes its signal transmission. An electronic fingerprint makes it possible to identify a wireless device by its unique radio transmission characteristics. Radio fingerprinting is commonly used by cellular operators to prevent cloning of cell phones. A cloned cell phone will have a same numeric equipment identity but a different radio fingerprint. Essentially, each transmitter (cell phones are just one type of radio transmitter) has unique rise time signature when first keyed caused by the slight variations of component values during manufacture. Once the rise time signature is captured and assigned to a callsign, the use of a different transmitter using the same callsign is easily detected. Such systems are used in military signals intelligence and by radio regulatory agencies such as the U.S. Federal Communications Commission (FCC) for identifying illegal transmitters. They are also used for assessing usage for billing purposes in Subscriber Mobile Radio (SMR) systems. ... Read more

Description:
Bacterial communities associated with the plant-parasitic nematode Meloidogyne fallax egg masses were compared with those present in the rhizoplane. Two agricultural soils with different nematode population dynamics were used in a glasshouse study, with either potato or tomato as host plant for the nematode. DNA fingerprints and bacterial community level physiological profiles (CLPP) were studied using PCR-DGGE of 16S rRNA genes and Biolog Eco MicroPlates. CLPP and DNA fingerprinting both showed differences between egg mass and rhizoplane bacterial communities. PCR-DGGE showed some bands specific to the egg mass samples. These bands were present in egg masses from both soils. This study shows that egg masses of M. fallax have a distinct bacterial community from that of the adjacent rhizoplane. Soil and host plant factors interactively influence the bacterial egg mass community. Differences in nematode population dynamics between the sample sites cannot be clearly related to the observed differences in the egg mass microbial communities. ... Read more

Description:
In order to elucidate the cause for the leaching of iodine in a flooded paddy field, we investigated the transformation of an iodine species affected by the water management of the paddy field. The increased concentration of iodide (I^-) in soil solution of a flooded paddy field suggested that I^- was leached from the soil under anaerobic conditions. The post-edge feature of X-ray absorption near-edge structure (XANES) for iodate (IO"3^-) spiked to soil totally disappeared after anaerobic incubation of the soils, and I^- was dissolved in the solution. On the other hand, I^- in contact with the soil was not likely to be oxidized to IO"3^- under aerobic incubation. Iodine was leached out in soil solution as I^- under anaerobic conditions, whereas part of the iodine species was retained by soil as I"2 or organoiodine both under anaerobic and aerobic conditions. ...

Description:
The early history of 'DNA fingerprinting' in the UK might have been different were it not for the accounts of two dramatic courtroom trials, made by the participants and the media, in the mid-1980s. But these reports, which misrepresented the importance DNA evidence had in the trials, left a strong impression on the British public and on judges on both sides of the Atlantic. These trials, widely considered to be the first 'victories' for DNA fingerprinting, have been frequently cited as proof of the utility and reliability of the technique, in both the UK and beyond. But in reality, it was the threat of DNA evidence being used rather than the integrity or validity of it that resolved these cases. At that time, DNA fingerprinting was still in its infancy, an untried and untested technology. ... Read more
