Research has shown that children with developmental coordination disorder rely more heavily on vision to perform movements skills than their typically developing (TD) peers. Yet, it is unclear that to what extent performance of motor skills depends on vision. The purpose of the current study was to investigate the contribution of visual information during walking between TD children and children with the risk of having developmental coordination disorder (DCDR). According to the psychological screen and total test score of the Movement Assessment Battery for Children-second version, thirty-two children (21 boys and 11 girls, mean age: 8.9, SD: 0.9 years) were divided equally into two motor competence groups. They were asked to walk along a 10-metre walkway and gait characteristics were recorded. They walked at a self-selected speed under four visual conditions: full vision, receiving vision for 150-ms and 100-ms within each 2 sec, and non-vision. The results showed that TD children walked faster and with longer steps and strides than DCDR children, regardless of the visual condition. Also, time variables including stance phase (s), single support (s), load response (s) and pre-swing (s) were significantly different between TD and DCDR children regardless of the visual condition. Besides, the speed of walking and the step and stride length decreased significantly while the occlusion time increased, regardless of the level of motor competence. The present findings suggest that withdrawing and limiting the visual information could affect differently in some of the parameters of the gait cycle in DCDR and TD children.

Five reaction schemes are suggested for the initiated nonbranched-chain addition of free radicals to the multiple bonds of the unsaturated compounds. The proposed schemes include the reaction competing with chain propagation reactions through a reactive free radical. The chain evolution stage in these schemes involves three or four types of free radicals. One of them is relatively low-reactive and inhibits the chain process by shortening of the kinetic chain length. Based on the suggested schemes, nine rate equations (containing one to three parameters to be determined directly) are deduced using quasi-steady-state treatment. These equations provide good fits for the nonmonotonic (peaking) dependences of the formation rates of the molecular products (1:1 adducts) on the concentration of the unsaturated component in binary systems consisting of a saturated component (hydrocarbon, alcohol, etc.) and an unsaturated component (alkene, allyl alcohol, formaldehyde, or dioxygen). The unsaturated compound in these systems is both a reactant and an autoinhibitory generating low-reactive free radicals. A similar kinetic description is applicable to the nonbranched-chain process of the free-radical hydrogen oxidation, in which the oxygen with the increase of its concentration begins to act as an oxidation autoinhibitory (or an antioxidant). The energetics of the key radical-molecule reactions is considered.

Quorum sensing is cell to cell communication process through chemical signals formally known as autoinducers. When the concentration of quorum sensing molecules reached threshold concentration bacteria are in active state or quorum state. In this article, we propose a mathematical model of quorum sensing systems and study this biological system numerically. Moreover, we compare the different numerical scheme with the batch culture of P.aeruginosa. We observed a negative diffusion coefficient which plays an important role in the quorum sensing mechanism.

At this study, it has been aimed to investigate the relations between the life goals and personality traits of teachers and it has been questioned whether their life goals differentiate according to a set of variables. Life Goals Scale (LGS) and Quick Big Five Personality Test (QBFPT) were used as data collection tools. When relations between personality traits and life goals of teachers were examined, statistically significant positive correlations were obtained. According to two-way ANOVA tests, it has been concluded that variables like gender and marital status together caused a significant effect on inner goals of teachers, F (1, 186) = 5.04, p = .026, η2 = .026. In terms of scores of extrinsic goals, perception of income and dissatisfaction of occupation variables composed a significant interaction effect as well and these two variables together composed a higher effect F (3, 181) = 3.053, p = .030, η2 = .048.

Wireless Multimedia Sensor Network(WMSN) is an extension of Wireless Sensor Network(WSN), where in addition to scalar sensors camera sensors are present. In wireless multimedia sensor networks (WMSNs), a high cost of processing and communicating the multimedia data is required. So it is important to reduce possible data redundancy. Data redundancy occurs due to overlapping of Field of view (FOV) of camera sensors. Data redundancy affects on the communication cost in terms of bandwidth used, CPU processing etc. increases. Therefore, camera sensors should only be actuated when an event is detected within their vicinity. Whenever an event takes place in a monitored region, it is first of all detected by the scalar sensors. The scalar sensors inform their corresponding camera sensors regarding the occurrence of event. In this paper, we propose a low-cost distributed actuation scheme which strives to turn on the least number of cameras to avoid possible redundancy in the multimedia data while still providing the necessary event coverage. Even though the camera sensors have heard from scalar sensors about an occurring event, they may not cover the event. These nodes unnecessarily undergo distributed camera actuation scheme and some or all of them are activated. So our objective is to keep such cameras in turned off condition and to activate optimum number of camera sensors. The basic idea of this scheme is the collaboration of camera sensors that have heard from scalar sensors about an occurring event to minimize the possible coverage overlaps and also their FoVs intersect with the event region. This paper also proposes a low-cost distributed actuation schemes for monitoring the event boundary. Simulation are presented to show the performance of our and other work in terms of coverage ratio, and the number of activated camera sensors under several random deployment schemes.

This study aims to evaluate the work of assessment methods of soil preparation tools to characterize their actions on the soil structure. The experiment was conducted during the 2015/2016 crop year at the Central Farm of National High School Of Agronomy. The objective of this study is essentially the analysis of the effect of three chains of agricultural tools (chain 1: deep plowing, chain 2: agronomic plowing, chain 3: Working without plowing), for the establishment of a durum wheat, on soil physical properties and the impact on root development and yield wheat. The results clearly show that the technique used has an effect on the evolution of moisture, porosity and cone index. The technique with agricultural labor has the best positive effect on moisture, porosity and soil penetration resistance. Root density is better in plots plowed in depth, root diameter meanwhile is best in the art without plowing, while root elongation is more important in agronomic plowing. it was concluded that the length of roots is strongly affected by soil parameters.

The study investigated the relationships between Hispanic students’ perceptions of instructors’ homophily and nonverbal immediacy behaviours and their perceptions of affective learning and content relevance. Utilizing convenience sampling, 141 Hispanic students completed a series of self-report scales. Multiple regression analysis found a significant relationship among these measures. Results further indicate that as students’ perceptions of immediacy and attitude homophily increased, perceptions of affective learning and content relevance were enhanced.

Nasopharynx is quite a concealed part of our body. Symptoms of early nasopharyngeal cancer usually are not obvious. They often appear as stuffy nose, nose bleeding, neck mass ,mild ear deafness ,headache and tinnitus, which are easy to be neglected. Therefore, many patients fail to have early diagnosis and are found in advanced stage when discovered. This brings great difficulty to treatment. In the present study we evaluated the early and most common presenting symptoms in order to be aware of it and hence early detection of the tumour with the hope of early treatment with good outcome and cure rate.

This paper is about wheat supply response in Kurdistan region of Irak. Simple OLS models, Nerlovian partial adjustment approach, is used to yield estimates on wheat production, acreage, and productivity, short run, long run elasticities, and growth rates in this region for the period 1990-2013. Production estimates depended on wheat prices, acreage, rainfall level, seed prices, fertilizer, pesticides, and fuel prices, labor costs, and a binary variable to take into account the effects of war and economic blockade (imposed by the UN). Whilst acreage supply includes lag variables, and other remaining variables included in the production estimates. Finally, productivity of supply contains one lag variable, wheat productivity and the other remainders of variables are identical to the previous models. Statistical analysis indicate that all variables were found significant at alpha = 0.10. Short run and long run elasticities of supply were 0.68% and 0.79% respectively. Acreage elasticities in the short run were 0.46% in the short run and 0.84% in the long run. Elasticities for short-run and long run of productivity were 0.24% and 037% respectively. The coefficient of adjustment for production, acreage and productivity were 0.009%, - 0.02 and 0.03 % respectively. This means that the annual growth rate in production is less than 1%, which is extremely low. The acreage growth rate (minus sign) means that the annual growth indicated a decline (a plausible reasons might be linked to a combination of factor, more use of fertilizer and pesticides in the ploughed acreage, rural migration to cities because of the war and its aftermath. Finally annual productivity growth rate indicated a modest again.

Methods for 3D-imagination of cells and sub-cellular components (chromosomes), with and without additional laser irradiation, were developed and tested. The main goal of the current study was directed to evaluation of technologies for precise identification of changes in the cellular components and compartments, composed of bio-molecules and intra-molecular structures, based on differences in their electron density. In this aspect, unlike the 2D-images, in the 3D-pictures, changes not only in the volume rates due to absorption, but also in the values of phase of light, passing through the observed objects, are available. Despite the destroy effect of the laser irradiation, this procedure, could allow the determination of presence and localization of respective intra-cellular structures, according to the exact place of the ray. On the other hand, in this way initial information about the nature of bio-macromolecules in the composition of complex structures, important about basic cell functions and processes, is possible. These features could give additional information, which could not be always noted by observation as 2D-objects.
