    Synthesis of Ferrocene Tertiary Amine Cyclopalladium Compounds and Its Application in Suzuki and Sonogashira Reactions

    Qi Yuan
    Ynones, also known as α, β-acetylenic ketones, have been widespread used in modern synthetic organic chemistry. They exist in biologically active compounds, and are used as vital building blocks in complex molecule synthesis. Consequently, a number of methodologies involving ynones have been developed to access a wide range scaffold using this simple building block. In this paper, the synthesis of a ferrocene tertiary amine cyclop

    On the Nature of Photon

    Alexander I. Korolev
    The article considers physical properties of photon as a quantum of electromagnetic wave in luminiferous medium. An experimental evaluation method for its energy and mass based on radiation pressure effect was presented. The of “photon amplitude” concept was introduced, through which energy is represented similarly to quantum (phonon) energy of elastic mechanical wave. A model of photon as a wave packet in the medium was considere

    Powerful Efficacy of GCSB-5 Treatment for Improving Fatigue and Motor Function in Multiple Sclerosis (MS): A Randomized Double Blind, Place-bo-Controlled Study

    Ji Yun Shin
    Multiple Sclerosis (MS) is the most common disability in young adults that requires early symptomatic treatment to prevent long-term disability. Among young adults, MS is the most common central nerv-ous system (CNS) chronic inflammatory illness that is characterized by demyelination in the CNS. However, current disease-modifying treatments are not sufficiently effective for preventing the variety of symptoms during the co

    A Method of Luminiferous Ether Registration

    Alexander I. Korolev
    The paper draws attention to the importance of the notion “luminiferous ether” in physics. There is a proposed method to register its flows generated by natural cosmic movements or created artificially. The work presents the results of ether wind searching with a prototype of the proposed installation located at the altitude of <30 m above sea level. Ether flows with speeds > 20 km/s are not found, which is consistent with the results of previous experiments.

    Dynamics and Green’s Functions of Uniaxial Nematic Liquid Crystals

    M.Y. Kovalevsky, V.T. Matskevych
    Dynamics of uniaxial nematic liquid crystals with rod-shaped and disc-shaped molecules in an external field is considered. For the systems under study thermodynamics is constructed and nonlinear dynamic equations accounting for the internal spatial anisotropy and molecules shape are derived. Densities of additive integrals of motion and corresponding flow densities are introduced in terms of thermodynamic potential. Analytical structure of low-frequency asymptotics of two-time Green’s functions ...

    Effect of Variable Sulfur Supply on Thiol Compounds and Arsenic Accumulation in Kandelia Obovata (S., L.) Yong Seedlings

    Dou Yangyang, Wu Guirong
    In the present study, Kandelia obovata (S., L.) Yong seedlings were exposed to As V(0, 30, 60 and 150 mg kg-1) under different levels of sulfur (0, 0.1, 0.2 and 0.4% (w: w)) supply. A highly significant negative correlation between arsenic concentration in leaves with sulfur treatment (r=-0.554, P...

    Validation of Analytical Method for Chromatographic Determination of Chlorimuron Ethyl Herbicide in Sediments

    Ramom Rachide Nunes, Bruno Henrique Froes Santos, Maria Olímpia Oliveira Rezende
    The present work describes the validation of an analytical method for chromatographic determination of chlorimuron ethyl herbicide (compound of sulphonylurea group) in sediments, in according with Brazilian legislation, following the guidance and normative documents of INMETRO (DOQ-CGCRE-008) and ANVISA (Resolution RE no 899 - 2003). The results show that the chromatographic method demonstrated to be selective, accurate, precision and linear over the concentration range of 5.0-1000.0 ug L-1...

    Forage Yield and Quality of Mungbean as Influnced by Harvesting Stage and Seed Rate

    Yousif Mohamed Zainelabdeen Hamed, Mozzamil A.M. Eltalib
    This study was conducted in gedarif research station farm for two seasons in 2013 and 2014. The objective was to determine optimum seed rate and time of harvesting mungbean for green forage and hay under rain fed conditions. The results showed different significant in three stage of cutting and three seed rate at different parameter as indicated by plant height, plant number, branch number, leave number and dry weight. The result showed highly significant between vegetative and boding stage. In ...
