In natural gas treatment, the removal of CO2 and H2S in acid gases is a critical concern. There are various purification technologies that can be used for the removal of acid gas impurities. Absorption of acid gas into amines is one preferred method in gas industries. In the past, single amines was used, but recently in order to improve absorption performance, mixed amines with different solubi...

Eight different zirconium phenoxyimine complexes were synthesized, characterized and tested as catalysts for ethylene polymerization. The phenoxyimine compounds were prepared by condensation of substituted salicylaldehydes with aliphatic and aromatic amines, the substituted salicylaldehydes from ortho substituted phenols and paraformaldehyde. The introduction of iodo substituents was achieved e...

Zaman M.Z., Bakar F.A., Selamat J., Bakar J.. (2010): Occurrence of biogenic amines and amines degrading bacteria in fish sauce. Czech J. Food Sci., 28: 440–449. The contents of biogenic amines histamine, putrescine, and cadaverine in fish sauce were determined and the bacteria isolated from the samples were evaluated for their amines degradation activity. Five fish sauce samples contained 62.5...

One school in Bali that also apply information technology in the learning process, namely SMK TI Udayana. Application forms of informa...

The first one-pot selective synthesis of unsymmetric tertiary amines is reported by the amination of two types of alcohols with primary amines via the development of a simple CuAlOx-HT catalyst and enables the synthesis of unsymmetric amines in a wide variety of primary amines and alcohols.

This paper describes how a traditional face-to-face course on enterprise systems is transformed into a blended learning course. Therefore the relevant theoretical background on blended learning and on a multi-perspective approach to enterprise systems is given. Furthermore the case study of an ERP e-learning project called “ERPeL” at the Saarland University is depicted. The components of the ER...

This study investigates engineering student preferences for blended learning adoption in higher education. No major study to date, however, has taken into consideration the influence of interaction, digital technology, social presence, and internet self-efficacy on student preferences for blended learning approach. This study is based on a sample of 126 students who can use Moodle platform at U...

The purpose of this article is to develop a design theory of blended learning curriculum in ways of establishing a model for designing such a curriculum and a model for designing an activity in a blended learning curriculum as well as demonstrating how these models can be utilized in a curriculum design. It first attempts to define what the essence of blended learning is by drawing on definitio...
