Marine Invertebrates as Bioindicators of Heavy Metal Pollution
(Scientific Research, 2014-12)Atmosphere, earth and water compose the environment. The presence of heavy metals in the environment has grown because of their large employment in some industrial and agricultural activities. Although these metals are ... -
Market Making, Liquidity Provision, and Attention Constraints: An Experimental Study
(Scientific Research, 2017-06)This paper uses an experimental electronic market to investigate the effect of limited attention on the market maker’s ability to provide liquidity and, thus, on aggregate market liquidity. I find that higher demands on ... -
A Mass Spectrometric Study of Kratom Compounds by Direct Infusion Electrospray Ionization Triple Quadrupole Mass Spectrometry
(Scientific Research Publishing, 2016-06)Mitragynine (MG) and its major metabolites 7-hydroxymitragynine (7-OH-MG) are two of the major components of the plant extract Kratom, which is a tree planted in Southeast Asia. Kratom has long been used by opioid-dependent ... -
A Mathematical Model for Magnetohydrodynamic Convection Flow in a Rotating Horizontal Channel with Inclined Magnetic Field, Magnetic Induction and Hall Current Effects
(2011-06)Closed-form and asymptotic solutions are derived for the steady, fully-developed hydromagnetic free and forced convection flow in a rotating horizontal parallel-plate channel under the action of an inclined magnetic field ... -
Mathematical Modelling of Mass Transfer and Free Convection Current Effects on Unsteady Viscous Flow with Ramped Wall Temperature
(2011-08)An exact analysis of the flow of an incompressible viscous fluid past an infinite vertical plate is conducted taking into account the presence of foreign mass or constant mass flux and ramped wall temperature. The dimensionless ... -

Maxillary Distraction Osteogenesis
(Scientific Research, 2015-02)Background: Distraction Osteogenesis is popular for long bones. And nowadays it has found its role in facial bone deficiency treatments. Purpose: We used our special designed Distractor for advancement of Maxillary ... -
Mazumder Effect of Liquid and Gas Velocities on Magnitude and Location of Maximum Erosion in U-Bend
(Scientific Research, 2012-06)Solid particle erosion is a micromechanical process that is influenced by flow geometry, material of the impacting surface, impact angle, particle size and shape, particle velocity, flow condition and fluid properties. ... -
Measurement of Fiscal Absorbing Capacity in Megacities and Analysis on Their Influence Factors—Empirical Research Based on Factor Analysis Combined with Panel Data
(Scientific Research, 2017-04)Fiscal absorbing capacity is an essential part of national capacity, whose shortcoming would drive local governments to raise capital through nonstandardized channels. Thus causing a negative effect on national ... -
Measurement of Rain Attenuation in Terahertz Wave Range
(Scientific Research Publishing, 2011-07)ain attenuation at 355.2 GHz in the terahertz wave range was measured with our new 355.2 GHz measuring system under rainfall intensities up to 25 mm/hr. Rain attenuation coefficients were also calculated using four ... -
Measurement of the Potassium Content of Different Food Samples with High Purity Germanium Detectors
(Scientific Research Publishing, 2016-07)Measurements of the potassium content of samples of food, performed with High Purity Germanium detectors, are presented in this paper. The potassium content was measured by identifying the 1460 keV photons produced in the ... -
Measuring the Technical Efficiency for the Shipping Banks—An Approach Using Data Envelopment Analysis
(Scientific Research, 2017-04)The international transportation industry involves various sectors, shipping being one with particular characteristics which differentiates it from others especially as relevant capital risk is concerned. Within this ... -
Mechanical and Thermal Properties of Chemically Modified Epoxy Resin
(Scientific Research, 2012-10)Diglycidyl ether of bisphenol-A (DGEBA), having number average molecular weight (Mn) 375, was modified by incorporating the hydroxyl terminated polybutadiene (HTPB) based prepolymer using isophorone diisocyanate as a ... -
