Vitamin C (ascorbic acid) is a water-soluble vitamin and essential for collagen, carnitine and neurotransmitter biosynthesis. Naproxen sodium is propionic acid derivative and anti-inflammatory non-steroid agent. The aim of the study was to assess genotoxicity of selected medicaments and their possible effects on genetic material using Allium bioassay. The treatment of onion bulbs with fresh solutions of Naproxen Sodium (Nalgesin S ®) and Vitamin C was performed using selected concentrations (550, 825 μg/ml and 250, 500, 1000 μg/ml respectively) in 72 hours time period. Control group was also set up.The microscopic parameters (mitotic index and chromosomal aberrations) of Allium root tips as well as the frequency of aberrant mitotic phases were analyzed. Both medicaments (vitamin C and Naproxen Sodium) caused increased frequency of abnormal mitosis when compared to control group.
Ground Moving Target Indicator (GMTI) and High Resolution Radar (HRR) can track position and velocity of ground moving target. Pose, angle between position and velocity, can be derived from kinematics estimates of position and velocity and it is often used to reduce the search space of a target identification (ID) and Automatic Target Recognition (ATR) algorithms. Due to low resolution in some radar systems, the GMTI estimated pose may exhibit large errors contributing to a faulty identification of potential targets. Our goal is to define new methodology to improve pose estimate. Besides applications in target tracking, there are numerous commercial applications in machine learning, augmented reality and body tracking.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
