Embryos of different species of vertebrate share a common organisation and often look similar. Adult differences among species become more apparent through divergence at later stages. Some authors have suggested that members of most or all vertebrate clades pass through a virtually identical, conserved stage. This idea was promoted by Haeckel, and has recently been revived in the context of cla...

The main purpose of the present meta-analysis was to examine the criterion-related validity of the 20-m shuttle run test for estimating cardiorespiratory fitness. Relevant studies were searched from twelve electronic databases up to December 2014, as well as from several alternative modes of searching. The Hunter-Schmidt’s psychometric meta-analysis approach was conducted to estimate the popula...

Climate change and the decreasing availability of fossil fuels require society to move towards sustainable and renewable resources. As a result, we are observing an increase in renewable energy production from sun and wind, as well as the development of electric vehicles or hybrid electric vehicles with low CO2 emissions. Because the sun does not shine during the night, wind does not blow on de...

Objective To explore the etiology, incidence and methods to prevent and treat severe retinopathy of prematurity (ROP), which is rapidly becoming a threat to the vision of babies in areas of the world where increasing numbers of premature babies are surviving. Data sources The data used in this review were mainly from Medline and PubMed published in English. The search term was “retinopathy of p...

Most sounds of interest consist of complex, time-dependent admixtures of tones of diverse frequencies and variable amplitudes. To detect and process these signals, the ear employs a highly nonlinear, adaptive, real-time spectral analyzer: the cochlea. Sound excites vibration of the eardrum and the three miniscule bones of the middle ear, the last of which acts as a piston to initiate oscillator...

The increase in the incidence of ischaemic heart disease and acute myocardial infarction (AMI) in both high- and low-income countries necessitates the development of myocardial salvaging/protection interventions, to be applied alongside standard reperfusion therapies. Although the phenomenon of ischaemic preconditioning (IPC) is associated with the desired protective capacity, the necessity of ...

Received 25 October 1991 . Abstract. Solid state lasers have undergone a renaissance since the development of reliable and cheap laser diodes which can be used as pump sources. The result is compact, eflicient laser sources which are attractive for a wide range of applications. This review summarizes the properties of laser diodes which are advantageous for pumping solid state lasers and descri...

This article review has focused on the article: “A guide to taking a patient’s history”. This article was authored by Hilary Lloyd and Stephen Craig and published in the Journal of Nursing Standard in 2007 . The article describes the procedures used in recording the account of the patient’s problem. The article recognizes the importance of having well defined procedures for recording patient hi...

Compartment syndrome has been deŽ ned as “a condition in which increased pressure within a limited space compromises the circulation and function of the tissues within that space”.1 It is most commonly seen after injuries to the leg2-5 and forearm6-8 but may also occur in the arm,9 thigh,10 foot,11-13 buttock,14 hand15 and abdomen.16 It typically follows traumatic injury, but may also occur aft...
