Biotic interactions can shape phylogenetic community structure (PCS). However, we do not know how the asymmetric effects of foundation species on communities extend to effects on PCS. We assessed PCS of alpine plant communities around the world, both within cushion plant foundation species and adjacent open ground, and compared the effects of foundation species and climate on alpha (within-micr...
Adverse antenatal maternal environments during pregnancy influence fetal development that consequently increases risks of mental health problems including psychiatric disorders in offspring. Therefore, behavioral and brain alterations caused by adverse prenatal environmental conditions are generally considered as deficits. In this article, we propose a novel hypothesis, along with summarizing a...
In this paper, we propose an audio-visual speech recognition system for a person with an articulation disorder resulting from severe hearing loss. In the case of a person with this type of articulation disorder, the speech style is quite different from with the result that of people without hearing loss that a speaker-independent model for unimpaired persons is hardly useful for recognizing it....
Water deficit stress is the main limiting factor of crop growth and yield in arid and semi-arid environments. Hyssop (Hyssopus officinalis L.) is one of the most important medicinal plants that have numerous medical uses. In order to study the effect of drought stress on physiological and morphological traits of Hyssop, an experiment based on randomized completely design was conducted with four...
Being brittle and having low thermal conductivity, refractories suffer damage and sometimes fail in service as a result of thermal shock. While the approach of those making fine-grained technical ceramics is to make their products sufficiently strong to withstand thermal stresses the refractory technologist is more cunning. He uses, often little known, devices to provide resistance to thermal s...
main goal in the management of patients with severe traumatic brain injury (tbi) is control of intracranial pressure (icp). decompressive craniectomy is an accepted technique for control of refractory intracranial hypertension in patients with severe tbi. because of high complication rate after decompressive craniectomy, new techniques such as basal cisternostomy have developed. we herein repor...
Water deficiency is an important factor for plant growth in arid environments. Foliar application of methanol in C3 plants is believed to be more important in water stress tolerance. In order to evaluate the effects of foliar application of methanol on photosynthetic features, chlorophyll fluorescence and chlorophyll content of lentil under water deficit stress, a factorial experiment in comple...
Virtual Geographic Environment Cognition is the attempt to understand the human cognition of surface features, geographic processes, and human behaviour, as well as their relationships in the real world. From the perspective of human cognition behaviour analysis and simulation, previous work in Virtual Geographic Environments (VGEs) has focused mostly on representing and simulating the real wor...
Explorative learning plays a major role when users face new functionality. Nevertheless, the multi-user character of groupware makes explorative learning more difficult. Users are often unable to understand the way certain functions work because they cannot perceive the effects of the functions’ execution. This problem gets more severe with tailorable groupware. Therefore, we propose exploratio...
