This paper presents a short overview of blended learning, showing arguments for and against these concepts. Potential blended learning scenarios are described that vary depending on the degree of instructor involvement, learner self-organisation and on-line moderation or coaching. The paper ends with an example of successful application of a blended learning concept in industry. Definition of B...

As Computer-Assisted Language Learning (CALL) has taken an important role in foreign language teaching and learning, not only is concrete data about the usefulness of technologymediated environments for these purposes necessary, but also how the learning process is improved in such environments when learner training for CALL. The objective of this paper is to present an investigation which soug...

Utilization of hemicelluloses from biomass energy is an important approach to explore renewable resources. A convenient, quick, and inexpensive method for the preparation of blended films from quaternized hemicelluloses (QH) and carboxymethyl cellulose (CMC) was introduced into this study. QH and CMC solution were first mixed to form homogeneous suspension, and then were dried under vacuum to f...

Effects of chemical compositions changes of blended-cement pastes (BCPCCC) on some strength gains of blended cement mortars (BCMSG) were monitored in order to gain a better understanding for developments of hydration and strength of blended cements. Blended cements (BC) were prepared by blending of 5% gypsum and 6%, 20%, 21%, and 35% marble powder (MP) or 6%, 20%, 21%, and 35% brick powder (BP)...

The effect of processing (homogenization, lyophilization, acid-extraction) meat products on iron uptake from meat combined with uncooked iron-fortified cereal was evaluated using an in vitro digestion/Caco-2 cell model. Beef was cooked, blended to create smaller meat particles, and combined with electrolytic iron-fortified infant rice cereal. Chicken liver was cooked and blended, lyophilized, o...

The combustion and emission characteristics of ethyl levulinate (EL)– diesel blended fuels were investigated using engine bench tests. Blended fuels properties, including the kinematic viscosity (KV), density, EL proportions, oxygen content, cetane number (CN), and lower heating value (LHV) were considered. The combustion and emission characteristics of brake-specific fuel consumption (BSFC), a...

This study attempts to explore the teaching process and effect in curriculum ‘Management of Nonprofit 
 Organizations’ through a hybrid mode based on SPOC (small private online courses, SPOC). In this study, 32 undergraduate students who majored administrative management were randomly divided into two groups; control group adopted traditional mode, experimental blended mode. After end each...

the benefits of using mineral admixtures as a partial replacement of portland cement (pc) are well established in the literature. economic and environmental advantages by reducing co2 emissions are well known. this paper examines the influence of intergrinding and separate grinding on the amount of energy consumption, blaine fineness and particle size distribution (psd) of blended cements, name...
