Biological age (BA) and mental efficiency (ME) were studied in truck drivers. The study demonstrated the features of the systemic organization of the functions that determine ME depending on the age and length of service. Premature age-related changes in psychophysiological indices were just “risk indicators” in truck drivers.

Efficient and rapid solubilization of biological material
Analytical Biochemistry, 1970Abstract Solid animal tissue can be rapidly solubilized with BBS-2 and counted by liquid scintillation spectrometry with excellent efficiencies reported for weak beta emitters. A more prolonged, tedious, and costly process is involved with the solubilization of solid tissue with NCS reagent, although large samples may be accommodated by this reagent ...

An efficient compressor for biological sequences
2013 3rd IEEE International Advance Computing Conference (IACC), 2013This paper introduces a state of art compressor for DNA sequences that makes use of a replacement method. The replacement method introduces words and a word based compression scheme is used for encoding. The encoder uses frequency distribution for assigning the code of words. The designed statistical compression algorithm is efficient and effective for

Biologically inspired highly efficient buoyancy engine
SPIE Proceedings, 2012Undersea distributed networked sensor systems require a miniaturization of platforms and a means of both spatial and temporal persistence. One aspect of this system is the necessity to modulate sensor depth for optimal positioning and station-keeping.

Efficient Updating of Biological Sequence Analyses
IEEE Journal of Selected Topics in Signal Processing, 2008We present a novel approach for reducing the computational complexity of updating homologies produced by a wide class of popular state-of-the-art algorithms in comparative computational biology. The algorithms that we consider use hidden Markov models (HMMs) and a Viterbi recursion to evaluate matches between sequences, or between a sequence and models.

Biological decomposition efficiency in different woodland soils
Oecologia, 1983The decomposition (meaning disappearance) of different leaf types and artificial leaves made from cellulose hydrate foil was studied in three forests - an alluvial forest (Ulmetum), a beech forest on limestone soil (Melico-Fagetum), and a spruce forest in soil overlying limestone bedrock.Fine, medium, and coarse mesh litter bags of special design were ...

Some Physical Aspects of Relative Biological Efficiency
The British Journal of Radiology, 1957After surveying the broad nature of the problem of relative biological efficiency, an account is given of methods which have been used to characterise the quality of ionizing radiations. These former methods have ignored the phenomenon of secondary or δ-track formation and reference is made to treatments which take this factor into account. The concept

Biological applications of efficient luminogenic aggregates
2021Fluorescence have found wide scope of application in biological science and biomedical field since its discovery, due to the real time, in situ and non-invasive characteristics. Molecules that emit fluorescence is called fluorophores or luminogens. Organic fluorophores have been widely used in biological applications. However, most organic fluorophores

Efficiency of Biological and Artificial Gills
2004An artificial gill is a device for the uptake of oxygen from water to air through a gas permeable membrane, driven by an oxygen partial pressure difference between the water and air. It enables humans to breathe under water, thereby extending the time that can be spent underwater, whether in scuba diving, sea rescue, sea exploration, or in a sea-bed ...
