Microsaccade research has recently reached a critical mass of studies that allows, for the first time, a comprehensive review of how microsaccadic dynamics change in neurological and ophthalmic disease. We discuss the various pathological conditions that affect microsaccades, their impact on microsaccadic and other fixational eye movement dynamics, and the incipient studies that point to micros...
The protagonist of my second novel, The Busker, is a singer-songwriter who seeks to use the Occupy LSX movement as a way of promoting his protest songs. In this paper, I will examine the ways in which folk music allows singers to “say whatever needs to be said... at the time when it needs to be said” (Guthrie in Jackson, 2007:40) and how this character provided the frame to investigate the Occu...
The objective of this study was to evaluate the anticipation time and kinematic factors in the movement of goalkeepers' center of mass when making a long-distance throw in handball. The sample group was composed of 14 goalkeepers and field players. A force platform was used to measure the force of the goalkeepers' reaction movements, while the throwers' movements were recorded with high-speed c...
Here in this article, the focus is drawn toward spread of #MeToo Movement and how social media played a crucial role its expansion. With movement, dreadful wave fright came to people all positions whether personals were actors, government officers, politicians, singers, minors, whatnot which discussed quite detail here major point coverage that needs be paid attention mass media. Focusing clear...
Transport of the earth surface material associated with diffusion brings a landform change, and the resulted sediment or debris thickness is approximated by a normal distribution. The essential feature of this geomorphic process is described in terms of the transport distance and the spatial spreading of the masses. A unit mass on a slope may move at a rate b downward and spread at a diffusivit...
چکیده: سنتز ایلیدهای پایدار فسفراز واکنش بین تری اتیل فسفیت و استرهای استیلنی در حضور فتالیمید ارائه گردیده است. محصولات از طریق طیف های ir ، mass و ( , 31p , 13c h 1) nmr شناسایی شدند. سنتز استرهای فسفونات از واکنش بین تری اتیل فسفیت و استرهای استیلنی در حضور p-کروزول و 2و 6 دی متیل فنل و دایمدون ارایه گردیده است. محصولات از طریق طیف های ir ، mass و ( , 31p , 13c h 1) nmr شناسایی...
The relationships between damage-induced electropotential waves (EPWs), sieve tube occlusion, and stop of mass flow were investigated in intact Cucurbita maxima plants. After burning leaf tips, EPWs propagating along the phloem of the main vein were recorded by extra- and intracellular microelectrodes. The respective EPW profiles (a steep hyperpolarization/depolarization peak followed by a prol...
Maximum power production during multi-joint tasks increases as children grow older. Previous research suggests that in adults, maximum power production in jumping is related to lower limb stiffness. In a developmental context, the question arises as to whether the relationship between maximum power production and lower limb stiffness is age-dependent. The purpose of this study was to investigat...
Information on the effects of obesity on the biomechanics of whole body movement control in children is limited. The purpose of the current study is to test the hypothesis that during a simple pick up task, overweight and obese children will organize their whole body movements differently than those in normal weight children. Twelve children who were overweight or obese (5-13 years old) and twe...
Many goals of human motor behavior, such as reaching out to hold a child’s hand, specify the end point of movement but do not constrain the movement made between initial posture and final target. In this issue, Dingwell et al., pp. 1158–1170, write about a newly discovered normal human behavior that challenges a classic hypothesis that people plan such movements to optimize hand-trajectory smoo...
