in order to investigate the characteristics of in vitro microtuberization of potato cv. agria in response to the two triazole anti-gibberellin, paclobutrazole and uniconazol, two independent experiment in five concentrations (0, 0.08, 0.16, 0.32, 0.64 mg/l) of each compound were carried out with four replications for each treatment in a completely randomized design. in this experiment percent o...

In this study, the force-length characteristics of the in vivo medial (GM) and lateral (GL) heads of the human gastrocnemius muscle were estimated from measurements in eight healthy male subjects. This involved: 1) dynamometry-based measurements of the moment generated during maximal isometric plantar flexion; 2) ultrasound-based measurements of fascicular length and pennation angle; and 3) ult...

abstract considering to importance and high genetic diversity of pear (pyrus communis l.) in iran, a study was conducted on the effect of genotype on fruit physicochemical properties and qualitative characteristics of six mature european pear genotypes in teheran, iran environmental conditions. in this study some physicochemical fruit properties and qualitative characteristics such as: fruit le...

In the present study, the in vivo force-length relations of the human soleus (SOL) and tibialis anterior (TA) muscles were estimated. Measurements were taken in six men at ankle angles from 30 degrees of dorsiflexion to 45 degrees of plantarflexion in steps of 15 degrees, and involved dynamometry, electrical stimulation, ultrasonography and magnetic resonance imaging (MRI). For each muscle and ...

length distribution is a statistical property of datasets and indexes in random-permutations-based DNA strings analysis. This property also affects other algorithms used for the same purposes. We report on results of preliminary analysis of basic resolution-length distribution properties of human DNA, with implications for random-permutations-based algorithms. We also discuss some of the implic...

Effects of decreasing stimulation frequency on length-force characteristics were determined for rat medial gastrocnemius muscle. The peripheral nerve was stimulated supramaximally with a succession of twitch and frequencies of 100, 50, 40, 30, and 15 Hz. Active peak tetanic and twitch forces and active muscle geometry were analyzed. Optimal muscle length and active slack length shifted signific...

endozoochory is one of the seed dispersal modes through animal’s digestive systems transmission and the increases rate germination and plant establishment. the aim of this study, investigated the relationship between seed characteristics and the passage through the digestive tract of livestock and domestic animals (cattle, sheep and goats) in the 7 species perennial grass 8 species perennial fo...

in order to investigate the effects of plant growth promoting bacteria on growth characteristic of wheat, an experiment was conducted at the research greenhouse, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a completely randomized design based on factorial arrangement (3×6) with three replications was used. the first factor consisted of three cultivars of wheat (c...
