Caries correction factors applied to a Punic (6th - 2nd BC) population from Ibiza (Spain)

Caries correction factors were applied to a Punic (6th-2nd century BC) rural sample from the island of Ibiza (Spain). Data obtained on dental caries and ante-mortem tooth loss provided a corrected rate of 12.8% of teeth with caries. This result, in conjunction with other sources of information such as stable isotope analysis and documentary evidence, indicated a diet based on terrestrial protein (mainly carbohydrates) and a low component of marine protein. The paper suggests further research avenues and promotes the use of caries correction factors in archaeological populations

Physical anthropology in Europe and beyond

Methodologies and legislative frameworks regarding the excavation, retrieval, analysis, curation and potential reburial of human skeletal remains different throughout Europe. As work forces within Europe and beyond have become increasingly mobile and international research collaborations are steadily increasing, the need for a more comprehensive understanding of different national research traditions, methodologies and legislative structures within the academic and commercial sector of physical anthropology has arisen. Establishing how human osteoarchaeology is practiced and dealt with throughout Europe and beyond will promote sharing knowledge between countries and form the basis for pan-European exchanges and discussions on the best practice. The current paper focuses on an ongoing project entitled ‘Physical Anthropology and Legislation: European Perspectives and Beyond’ and provides insight into some of the results obtained so far

A CMOS self-contained quadrature signal generator for soc impedance spectroscopy

This paper presents a low-power fully integrated quadrature signal generator for system-on-chip (SoC) impedance spectroscopy applications. It has been designed in a 0.18 µm-1.8 V CMOS technology as a self-contained oscillator, without the need for an external reference clock. The frequency can be digitally tuned from 10 to 345 kHz with 12-bit accuracy and a relative mean error below 1.7%, thus supporting a wide range of impedance sensing applications. The proposal is experimentally validated in two impedance spectrometry examples, achieving good magnitude and phase recovery results compared to the results obtained using a commercial LCR-meter. Besides the wide frequency tuning range, the proposed programmable oscillator features a total power consumption lower than 0.77 mW and an active area of 0.129 mm2, thus constituting a highly suitable choice as stimulation module for instrument-on-a-chip devices

An Investigation of Red Fox (Vulpes vulpes) and Eurasian Badger (Meles meles) Scavenging, Scattering, and Removal of Deer Remains: Forensic Implications and Applications

Within northwest Europe, especially the United Kingdom, the red fox (Vulpes vulpes) and the Eurasian Badger (Meles meles) are the largest wild scavengers capable of modifying a set of remains through scavenging. Knowledge of region-specific and species-typical scavenging behaviors of scavengers within the crime scene area and surroundings can aid in more efficient and accurate interpretations. The scavenging behaviors of captive and wild foxes and badgers were recorded and compared through actualistic methods and direct observation. The scavenging by wild foxes and badgers of surface-deposited baits and whole deer (Cervus nippon; Capreolus capreolus) in a woodland was observed and analyzed. Wild foxes were found to scavenge deer more frequently than badgers. The scavenging of deer remains by foxes was also compared with forensic cases. The scavenging pattern and recovery distances of deer and human remains scavenged by foxes were similar but were potentially affected by the condition and deposition of a body, and the presence of clothing

Dengue Serotype Differences in Urban and Semi-rural Communities in Ecuador

Dengue is a major vector-borne infection causing large outbreaks in urban communities in tropical regions. During the period 2010- 2014; 434 serum samples from febrile patients were collected from a  semi-rural community hospital located in the norwestern region of Ecuador. Dengue virus (DENV) was investigated by reverse transcriptase PCR; a total of 48 samples were positive for dengue. During our study we detected  DENV-2 and DENV-3 from 2010 to 2013 and the four  DENV  serotypes during the period 2013-2014.  Surprisingly, our results contrasted with surveys carried out in urban centers throughout the  Ecuadorian Coast in which  DENV-1, DENV-2 and DENV-4 were prevalent during years 2010-2013 and only 2 serotypes  (DENV-1 and DENV-2) in 2014.These results suggest  that dengue viruses in semi-rural communities didn’t  originate in the Ecuadorian cities.  &nbsp

Quantum mechanical spectral engineering by scaling intertwining

Using the concept of spectral engineering we explore the possibilities of building potentials with prescribed spectra offered by a modified intertwining technique involving operators which are the product of a standard first-order intertwiner and a unitary scaling. In the same context we study the iterations of such transformations finding that the scaling intertwining provides a different and richer mechanism in designing quantum spectra with respect to that given by the standard intertwiningComment: 8 twocolumn pages, 5 figure

Población vacuna en la sabana de Bogotá y el valle de Ubaté.

En este trabajo se presentan algunos datos relacionados con el censo ganadero realizado por la Regional 1 del ICA, en la sabana de Bogotá y el valle de Ubaté, durante el año de 1974. En él se consideró: el medio geográfico y ecológico, los municipios en la zona, el número y tamaño de las explotaciones, la superficie en pastos, la cantidad de animales, los bovinos registrados en las Asociaciones Holstein y Normando, los terneros recién nacidos y sacrificados, así como el ganado mayor en el mercado de Bogot

Redefining forensic anthropology in the 21st century and its role in mass fatality investigations

Forensic anthropology is a dynamic field, with its definition having to reshape itself and expand continuously. The challenges faced as well as its potential have grown in synergy with other areas in forensic science. In academia, as well as in practice, the discipline has seen much specialisation in different areas. In particular in recent years, the importance of the forensic anthropologist has led to an increase volume of casework for these scientists, and an important role in disaster victim identification worldwide. This paper sees the need for a revised definition which reflects the nature of the work, both with the living as well as with the dead, in individual domestic cases or international human rights’ investigations. A review of the work undertaken by forensic anthropologists is provided with special emphasis on mass fatality incidents. This paper also explores the discipline’s contribution to DNA analysis and positive identification. It is important to highlight the forensic anthropologists’ role and their potential in any deployment of a National or International Disaster Victim Identification team
