Hybrid processes have received more attention in pollutant removal due to the combination of advantages each process. A membrane combined with absorption was developed and studied for volatile organic compounds (VOCs) from lab industrial scale. The ionic liquid containing 1-butyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide ([Bmim][NTf2]) showed competitive on toluene. An industrial-l...

Let V be Euclidean space. Let W ⊂ GL(V ) be a finite irreducible reflection group. Let A be the corresponding Coxeter arrangement. Let S be the algebra of polynomial functions on V. For H ∈ A choose αH ∈ V ∗ such that H = ker(αH). The arrangement A is known to be free: the derivation module D(A) = {θ ∈ DerS | θ(αH ) ∈ SαH} is a free S-module with generators of degrees equal to the exponents of ...

Motivated by a scheduling problem encountered in multicast environments, we study a vertex labelling problem, called Directed Circular Arrangement (DCA), that requires one to find an embedding of a given weighted directed graph into a discrete circle which would minimize the total weighted arc length. Its decision version is already known to be NP-complete when restricted to sparse weighted dir...

Since but little work has been done on the innervation of the esophagus, it seemed to me that it might be both interesting and profitable to determine, by means of the inlru-&am methylene blue method, the arrangement and terminations of the nerves in this part of the digestive tract, to verify the results already gained by other methods and, so far as practicable, to compare the innervation of ...

Hyperplane arrangements are very interesting combinatorial objects and many results can be found in the literature. For instance, several papers [1, 2, 6, 7] are concerned with the characteristic polynomials and the number of regions of a hyperplane arrangement. In his paper [9], Stanley reviewed various hyperplane arrangements raising interesting questions, one of which is related to the follo...

This study examined the impact of monetary policy on unemployment in Pakistan. The time-series data for 1977 to 2019 was taken and ARDL technique is used estimation. Unemployment as a dependent variable along with other control variables while money supply core independent research. It concluded that related arrangement not just contributes observing past patterns additionally future projection...

usually both ends of a transformer winding are at the same side of the magnetic core. with this arrangement there are automaticaly the same number of the turns for each winding in both core windows next to the middle leg of a three phase three leg core type transformer. contrary to this arrangement it is possible to put the two ends of a winding at the different sides of the core. in this case ...
