The Beaker phenomenon in Britain is typically represented by a particular form of pottery and its inclusion graves with flexed or crouched inhumations referred to as burials. Analysis the full range burial evidence, however, reveals high degree variability funerary rites including cremation skeletal disarticulation. Summed probability distribution analysis radiocarbon dates provides evidence fo...

Moulting behaviors in trilobites are a crucial strategy during development. Previous studies have demonstrated inter-and intraspecific variability of moulting behavior trilobites. Currently, ecdysial motifs for considered not stable even within species and fewer detailed dealt with single trilobite Here large sample meraspid to holaspid exuviae Arthricocephalites xinzhaiheensis (131 specimens) ...

Palatopharyngeal dysfunction may take place when palatopharyngeal valve is unable to perform its own closing due to a lack of tissue (palatopharyngeal insufficiency) or lack of proper movement (palatopharyngeal incompetence). Palatopharyngeal insufficiency induces nasal regurgitation of liquids, hypernasal speech, nasal escape, disarticulations and impaired speech intelligibility. Prosthetic ma...

Synovial chondromatosis of the elbow is an uncommon condition. However, a chondrosarcoma arising from the former is remarkably rare. The authors report a case of an elbow chondrosarcoma secondary to synovial chondromatosis in a 38-year-old woman. Before the development of chondrosarcoma, the patient underwent 3 operations and 3 sessions of radiosynovectomy because of continuous recurrence of sy...

Ecological interactions, including symbiotic associations such as mutualism, parasitism and commensalism are crucial factors in generating evolutionary novelties and strategies. Direct examples of species interactions in the fossil record generally involve organisms attached to sessile organisms in an epibiont or macroboring relationship. Here we provide support for an intimate ecological assoc...

This paper investigated the gender implications of involuntary resettlement at Karimenu II Dam. The study employed Impoverishment, Risks, and Reconstruction (IRR) model developed in late 1990s by World Bank coined Michael Cernea (2002). It provides a conceptual tool for identifying inherent risks that may cause impoverishment through displacement resettlement. He identified 8 Involuntary Resett...

Two hundred and forty-eight high-grade central osteosarcomata were treated by amputation or disarticulation; in 5.2 per cent the tumour recurred at the amputation site. The following causes may be responsible for local recurrence: the level of the amputation is too close to the tumour; there is an unrecognised intramedullary extension of the tumour; during a previous block resection tumour cell...

AN THE course of routine practice, the orthopedic surgeon is frequently confronted with the task of dealing with hands that are damaged by trauma or disease or that are otherwise nonfunctional owing to any of a variety of causes. In all such cases, he is called upon to decide whether or not to undertake amputation of parts of the hand or amputation through the wrist, with the expectation of lat...

OBJECTIVE To compare energy cost and stride characteristics during walking with 3 different types of prostheses in a person with bilateral knee disarticulations. DESIGN Single-case study. Setting Pathokinesiology laboratory. PARTICIPANT A subject with bilateral knee disarticulations and bilateral transradial amputations secondary to meningococcemia with purpura fulminans. INTERVENTIONS No...

The dung beetle subfamily Scarabaeinae is a cosmopolitan group of insects that feed primarily on dung. We describe the first case of an obligate predatory dung beetle and contrast its behaviour and morphology with those of its coprophagous sympatric congeners. Deltochilum valgum Burmeister killed and consumed millipedes in lowland rainforest in Peru. Ancestral ball-rolling behaviour shared by o...
