—we present in this work a numerical study of pollutant dispersion resulting from a bent chimney around twin obstacles placed in the lee side of the source. A three-dimensional numerical model with the turbulent Reynolds Stress Model (RSM) and a non-uniform grid system was used to examine the effects of a double tandem obstacle cubic on the development of the incoming flow. The results obtained...

strip tearing during cold rolling process has always been considered among the main concerns for steel companies. several works have been done so far regarding the examination of the issue. in this paper, experimental data from cold rolling tandem mill is used for detecting strip tearing. sensors are placed across the cold rolling tandem mill. they receive information on parameters (such as ang...

Layered periodic foundations (LPFs) with identical unit cells have been proposed as a type of seismic metamaterials due to the unique dynamic characteristic attenuation zones. However, it is difficult design zones both comparatively low starting frequencies and large bandwidths for traditional LPFs cells. In this paper, combined layered (CLPFs) are by combining two different in tandem. Combined...

chemical hardness (), absolute electronegativity (), and electrophilicity () have importantapplications in inorganic chemistry. these concepts are defined quantitatively as � � �� � ����,� � �� � ����, � � ������where i is the ionization energy and a is the electron affinity. in thisstudy, graphical method was used to see the relation of electron configuration with chemicalhardness, absolute...

in 2005, a. abdollahi and a. rejali, studied the relations betweenparadoxical decomposition and configuration for semigroups. in thepresent paper, we introduce one other concept of amenability typeon semigroups and groups which includes amenability of semigroupsand inner-amenability of groups. we have extend the previous knownresults to semigroups and groups satisfying this concept.

We examine the electrical and thermal characteristics of a photovoltaic module with three-terminal cell interconnection when partially shading solar by experimentally verified modeling. For multi junction tandem cells two- (2T), three- (3T), four-terminal (4T) architecture is conceivable. The 3T featuring combination parallel series combines advantageous 2T 4T without their drawbacks. build (PV...

background :according to numerous studies, fms-like tyrosine kinase 3, internal tandem duplication, and the d835 mutation are associated with a poor prognostic clinical outcome in acute myeloid leukemia patients. detection of the fms-like tyrosine kinase 3 mutation in patients who present with normal karyotype acute myeloid leukemia helps in both the understanding of the disease and the treatme...
