Abstract
  Inhibition of acetylcholinesterase and butyrylcholinesterase (AChE and BuChE) as two major forms of cholinesterases (ChEs) is considered as the common approach for the treatment of Alzheimer's disease (AD). The present study was done to explore the anticholinesterase inhibition property of coumarin Mannich ...  Read More

2. Effect of Calcination Rate on Performance of Co-precipitated Cu-MgO Catalyst in Hydrogenation of Furfural

Mohammad Ghashghaee; Samira Shirvani; Vahid Farzaneh; Samahe Sadjadi

Volume 30, Issue 1 , Winter 2019, Pages 13-21

http://dx.doi.org/10.22059/jsciences.2019.69628

Abstract
  Co-precipitated Cu-MgO catalysts were prepared and evaluated for the gas-phase hydrogenation of furfural. The effect of heating rate at the calcination step was studied by comparing the performance of three catalysts prepared via the same procedure but calcined at different heating rates. The results ...  Read More

3. A Crystallization-Induced Asymmetric Transformation using Racemic Phenyl Alanine Methyl Ester Derivatives as Versatile Precursors to Prepare Amino Acids

Samira Rahmani-Nezhad; Shima Dianat; Abbas Hadjiakhoondi

Volume 30, Issue 1 , Winter 2019, Pages 23-31

http://dx.doi.org/10.22059/jsciences.2019.69629

Abstract
  L-Tyrosine and L-Dopa are the precursors in the biological synthesis of amine neurotransmitters. On the other hand, phenylalanine as an aromatic amino acid (AAA) is a precursor in the synthesis of L-Tyrosine and L-Dopa. For some substrates such as amino acids, resolution by the formation of diastereomers ...  Read More

5. Fault Strike Detection Using Satellite Gravity Data Decomposition by Discrete Wavelets: A Case Study from Iran

ata eshaghzadeh; A. Dehghanpour; Roghayeh Alsadat kalantari

Volume 30, Issue 1 , Winter 2019, Pages 41-50

http://dx.doi.org/10.22059/jsciences.2019.69631

Abstract
  Estimating the gravity anomaly causative bodies boundary can facilitate the gravity field interpretation. In this paper, 2D discrete wavelet transform (DWT) is employed as a method to delineate the boundary of the gravity anomaly sources. Hence, the GRACE’ satellite gravity data is decomposed using ...  Read More
