conclusions the result of this study did not find an independent association between adhd and helmet use. results univariable analysis showed the mean of the age variable was significantly higher in the helmeted group, 26.94 ± 7.72 vs. 23.08 ± 7.7.32, (p < 0.001). the majority of the non-helmeted group was single (p < 0.001). subjects with secondary educational level were more often in the helm...

in this study, stability control of a three-wheeled vehicle with two wheels on the front axle, a three-wheeled vehicle with two wheels on the rear axle, and a standard four-wheeled vehicle are compared. for vehicle dynamics control systems, the direct yaw moment control is considered as a suitable way of controlling the lateral motion of a vehicle during a severe driving maneuver. in accordance...

permanent magnet synchronous motors are efficient motors, which have widespread applications in electric industry due to their noticeable features. one of the interesting applications of such motors is in underwater vehicles. in these cases, reaching to minimum volume and high torque of the motor are the major concern. design optimization can enhance their merits considerably, thus reduce volum...

ZIP (Zinc-regulated transporter, Iron-regulated transporter-like Protein, ZIP) plays an important role in uptake or transport Zn Fe plants. So studying ZIPs plant can help to elucidate the molecular mechanism for and transportation. Herein, we have cloned a novel transporter gene NoZIP3 from Nasturtium officinale root using rapid-amplification of cDNA ends (RACE) method, evaluated its function ...

Orally administered small molecules may have important therapeutic potential in treating COVID-19 disease. The recently developed antiviral agents, Molnupiravir and Nirmatrelvir, been reported to be efficient treatments, with only moderate side effects, especially when applied the early phases of this However, drug–drug drug–transporter interactions already noted by drug development companies a...

The Na+/H+ exchangers (NHE) are a family of proteins that regulate intracellular pH, sodium levels and cell volume, contribute to the control cycle, proliferation, migration vesicle trafficking. However, despite their physiological importance, detailed molecular-level structural information for NHE has been lacking. Although number prokaryotic structures sodium/proton antiporters known, it is n...

This study characterizes different MTP1 (metal tolerance protein)/ZAT (zinc transporter) homologs involved in zinc (Zn) homeostasis plants. BLAST analysis of AtMTP1 protein against 15 plant species showed 21 homologs. These generally contain ~400 residues, six transmembrane helices and cation transporter activity (GO:0008324), which can be utilized predicting Zn uptake mechanisms. genes having ...

In this study on-road gaseous emissions of vehicles are investigated using remote sensing measurements collected over three different periods. The results show that a high percentage of gaseous pollutants were emitted from a small percentage of vehicles. Liquified Petroleum Gas (LPG) vehicles generally have higher gaseous emissions compared to other vehicles, particularly among higher-emitting ...
