Chemical Dynamics of Monodispersed Iron Oxide Nanoparticles
This study is comprised of the synthesis and characterization of uniform fine particles of iron oxide in different shapes and sizes. Varying amounts of iron (III) chloride and sodium dihydrogen phosphate was heated at 98 oC for various periods, following the forced hydrolysis method. Scanning electron microscopic analysis showed that the shape and size of the precipitated particl...
متن کاملA least-constraint principle for population dynamics and reaction kinetics: Modeling entropy-controlled chemical hypercycles.
In this paper, we investigate the treatment of constraints in rate equations describing the temporal evolution of biological populations or chemical reactions. We present a formulation for arbitrary holonomic and linear nonholonomic constraints which ensures the positivity of the dynamical variables and which is an analog of Gauss' principle of least constraint in classical mechanics. The appro...
متن کاملChemical Statics and Dynamics
This is one of the text-books of Physical Chemistry edited by Sir Willam Ramsay. It views chemistry from the standpoint of the explanation of its phenomena by the physical laws which govern appreciable weights of substances, and it is shown that they operate equally in the changes which take place between individual mollecules during chemical reaction. It is pleasant to find that sharp distinct...
متن کاملSpectroscopy and chemical dynamics.
Chemical physics and molecular spectroscopy are topics with a traditionally strong emphasis in the department. Current research focuses on the spectroscopic characterization of transient molecules present in interstellar space and the preparation, control and chemistry of ultracold molecules and ions in the gas phase.

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
