Sharp lower and upper bounds for quasiconvex moments of generalized order statistics are proven by the use of the rearranged Moriguti’s inequality. Even in the second moment case, the method yields improvements of known quantile and moment bounds for the expectation of order and record statistics based on independent identically distributed random variables. The bounds are attainable providing ...

We modified a time-lapse recording to make a ‘flipbook’ of zebrafish embryogenesis. By flipping through the pages of this issue and watching the pictures in the upper corner of each even-numbered page, the dynamic cellular movements that form the zebrafish embryo can be visualized. The time-lapse record starts at the 2-cell stage (page 2 and Fig. 1B) and ends at the 16-somite stage (Fig. 1I), a...

Cladocera communities were studied in lotic and lentic environments of the Upper Paraná River floodplain, State of Mato Grosso do Sul, Brazil. A total of 63 species of Cladocera were identified in 108 samples. Of these, 24 species are considered new records for that floodplain, and one is a new record for Brazil. Chydoridae was the most representative family with 19 genera and 39 species.

Abstract We report about the Early Miocene Tagay fauna of Olkhon Island, largest island Baikal Lake. The is high scientific importance because diversity fishes, amphibians, lizards, snakes, turtles, manifold birds and mammals. lithology, geochemistry fossil record along Tagay-1 section allow reconstruction various palaeoenvironments, i.e. open water, shallow lakes with adjacent wetlands, riveri...

The archaeological record shows that from ca. 4000 BC onwards, Neolithic farming communities in Upper Egypt underwent a process of increasing social complexity. This included a rise in wealth inequality and hierarchy, settlement agglomeration, and the development of complex cultural ideology, all leading eventually to the emergence of a unified territorial state encompassing the whole Nile Vall...

The first crane fly (Diptera: Tipuloidea) fossil discovered in the Upper Jurassic Talbragar Fish Bed in Australia is described and illustrated. Eotipula grangeri sp. nov., described from a single specimen, is assigned to the family Limoniidae based primarily on the conformation of wing veins. It is the second and oldest record of Limoniidae from Australia, and the first of Jurassic age from the...

A new assemblage of arthropod cuticles from Upper Silurian rocks in Shropshire, England, includes at least two centipedes and a trigonotarbid arachnid. This unequivocal terrestrial fauna from the Silurian constitutes the earliest direct record of land animals. The presence of predatory arthropods suggests that complex terrestrial ecosystems were in place by the late Silurian (414 x 10(6) years ...

A chest roentgenogram demonstrates lumen collapse as the cause of ventilatory obstruction in an intubated patient. This problem is not restricted to defective tubes but may be caused by overinflation of the cuff in normal tubes. D espite the impressive record of endotracheal tubes as guardians of an unobstructed airway, human and mechanical failure causing these devices to become dangerous site...

Purpose Chronic Fatigue Syndrome (CFS) has an elusive diagnosis and etiology. Treatment focuses on alleviation of symptoms and improving a patient’s quality of life. The primary objective was to observe and record changes in a subject’s health related quality of life (HRQoL), using the SF 36Item Health Survey (SF-36), before and six months after a National Upper Cervical Chiropractic Associatio...

conclusions ultrasonography seems to be a safe and cost effective method to evaluate foreign bodies, especially radiolucent objects, in patients with penetrating trauma and suspicious of foreign bodies that may remain undiagnosed in radiography. availability of bedside ultrasound for emergency physicians is an important issue, since it is not possible to access the radiologist at any time of th...
