We have studied measurements of the cross section for e+e− → hadrons for centerof-mass energies in the range 20–209 GeV. We find an apparent excess over the predictions of the Standard Model across the whole range amounting to more than 4σ. As an example, we compare the data to predictions for a light scalar down-type quark which fit the excess well.
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...

This study chose 60 cases of cesarean section for patients with epidural anesthesia (EA) combined spinal epidural anesthesia (CSEA) surgery for clinical application research. Compared with EA, the CSEA could work well in subarachnoid anesthesia and epidural anesthesia. Although it was with less dosage, it had a faster and better effect, good muscle relaxant condition. It not only improved the q...
The effect of Gibberellic Acid (GA3) and Benzyladenine (BA) on Aloe vera was evaluated at pot cultivation conditions. This study was performed in two factorial test based on complete random plan and 4 repeats with 12 treatments. The main factor was included spraying, drip and spraying + drip. Secondary factor was included concentrations of GA3 and BA at 0, 100...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
The porosity distribution law of overlying strata in the goaf has an important guiding role distinguishing hidden disaster-causing factors goaf, such as gas enrichment area and spontaneous combustion area. Existing research is concentrated on a single working face (GSWF), adjacent (GAWF) must be different from that GSWF. By selecting Longshan Coal Mine engineering background applying theoretica...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
