The rod-like, contractile stalk of the single-celled peritrich Vorticella Convalleria can collapse into a tightly coiled helix in less than 1/60 second, a rate ~1000 times its cell body size per second. The contractile stalk (25um-300um in length, ~ 4um diameter) consists of several membranes stiffened by extracellular fibers and helical assembly of larger protein bundles, known as batonets, su...
Sugarcane (Saccharum spp.) is harvested during a 5-month period (October to March) in the Everglades Agricultural Area (EAA) of south Florida. The genetic and temporal variability of sugarcane sucrose concentration is well established, but sucrose accumulation curves have not been reported for the Canal Point (CP) clones used in Florida since 1977. The objective of this study was to compare suc...
Adaptive Intelligent Tutoring Systems (ITS) aim at helping students going through the resolution of a given problem in a principled way according to the desired outcomes, the intrinsic capabilities of the student, and the particular context in which the exercise takes place. These systems should be capable of acting according to mistakes, boredness, distractions, etc. Several works propose diff...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
abstract following innovations in the field of elt, a new topic which has recently attracted a lot of attention is metaphor analysis. although this area of research is still in its infancy in elt, it seems that the idea can shed more light on the puzzle of english language learning and teaching. therefore, the major aim of this study is to analyze language learning and teaching in formal a...
the main object of this study was to evaluate the effect of tillage and crop residues management of barley (hordeum vulgare l.) on quantification and qualification yield of corn (zea mays l.). treatments were laid out in complete randomized block design with seven treatments and three replications and include (1) fire of straw and stubble, plow, disc and furrower (2) gathering and transfer of s...
rots in maize. High yielding cultivars, increased plant densities, and improvements in soil fertility are generally Stalk lodging in maize (Zea mays L.) causes yield losses estimated accepted to have also contributed to increased stalk to range from 5 to 20% annually worldwide. Selection for rind penetrometer resistance (RPR) has proven useful in enhancing germplasm lodging. for stalk strength,...
Abstract Maize stalk lodging is the structural failure of prior to harvest and a major problem for maize (corn) producers plant breeders. To address this problem, it critical understand precisely how geometric material parameters influence strength. Computational models could be powerful tool in such investigations, but current methods creating computational are costly, time-consuming and, most...
