‎Let $p(z)$ be a polynomial of degree $n$ and for a complex number $alpha$‎, ‎let $D_{alpha}p(z)=np(z)+(alpha-z)p'(z)$ denote the polar derivative of the polynomial p(z) with respect to $alpha$‎. ‎Dewan et al proved‎ ‎that if $p(z)$ has all its zeros in $|z| leq k, (kleq‎ ‎1),$ with $s$-fold zeros at the origin then for every‎ ‎$alphainmathbb{C}$ with $|alpha|geq k$‎, ‎begin{align*}‎ ‎max_{|z|=...

dog rose (rosa canina l.) is one of the most important ornamental and medicinal plants which are used as a rootstock for ornamental roses such as rosa hybrid and rosa floribunda. in vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and in production of healthy and disease-free plants. micropropagation of rosa canina l. was revised, usin...

Introduction: High levels of homocysteine (Hcy) might accelerate dopaminergic cell death through oxidative stress and excitotoxicity. Folate plays an important role in the control of plasma levels of Hcy. In this study, effect of supplementation with folic acid on the 6-hydroxydopamine (6-OHDA)-induced Parkinsonism in rat and also serum level of Hcy was investigated. Methods: Rats were fed ...

Sir, We report here a study that was undertaken to investigate whether ciprofloxacin resistance in Gram-negative noso-comial pathogens is a surrogate marker for cross-resistance to non-fluoroquinolones. The organisms, Escherichia coli (n = 3315), Pseudomonas aeruginosa (n = 1370), Entero-bacter aerogenes (n = 252), Enterobacter cloacae (n = 495), Proteus mirabilis (n = 379), Serratia marcescens...

Objective Antinuclear antibodies (ANA) serve as screening tests for connective tissue diseases but have low specificity. In this pilot study, we aimed to identify patients with first-time positive ANA and musculoskeletal complaints and correlate serum soluble vascular adhesion molecules as biomarkers. Methods Prospective, observational study with 100 ANA-positive patients, comparing them to a...

Abstract: Patient’s symptoms could be used as features in Covid-19 classification. Using multi layer perceptron, the classification uses data set that contains patient’s diagnosis which has dan processes to see if patient is positive or not. This paper compare four activation function such identity, logistic, ReLu and tanh combined them with optimizer L-BFGS-B, SGD Adam. 5-fold 10-fold cross va...
