An important part of the systems development process is building models of real-world phenomena. These phenomena are described by many different kinds of information, and this diversity has resulted in a wide variety of modelling representations. Different types of information are better expressed by some representations than others, so it is sensible to use multiple representations to describe...

With the advent of social applications, the question arises of how organizations can utilize such technology for improving task performance. While social applications certainly bear the potential to trigger the development of radically new business models and business processes, we seek to study how the enrichment of IT-based routine work (simple tasks) by complementing social features (audienc...

New neurons are incorporated throughout life into the brains of many vertebrate and nonvertebrate species. This process of adult neurogenesis is regulated by a variety of external and endogenous factors, including environmental enrichment, which increases the production of neurons in juvenile mice and crayfish. The primary goal of this study was to exploit the spatial separation of the neuronal...

Nowadays, cross-lingual Information Retrieval (IR) is one of the greatest challenges to deal with. Besides, one of the most important issues in IR consists in the corpus vocabulary reduction in order to make possible to use in real situations some methods of IR such as the well-known vector space model. In this work, we have considered a vocabulary reduction process based on the selection of mi...

In this study, the effects of hydrogen and hydroxygen additions and oxygen enrichment on the emission characteristics of a gasoline engine (EF7) were investigated and compared with each other. The simulation was launched by GT-Power at different engine speeds with 5 % to 15 % volume fractions for both of oxygen and hydrogen enrichment and 4.5 % to 9 % volume fractions of hydroxygen addition in ...

A decline in learning and memory is a feature of the normal aging process and associated with neurodegenerative diseases such as dementia and Alzheimer's disease. Moreover, certain forms of dementia and memory loss are inevitable due to the normal aging process. The unavoidable effect of age on memory is an ongoing study, as the findings assist in identifying cortical functions of the brain. Hi...

Background: Developing and promoting empathy between couples can assist them in dealing with destructive communication patterns, increasing their satisfaction through effective dialogue and conversation, and, as a result, creating a safe place to meet emotional needs. The present study aimed to determine the effectiveness of Olson’s enrichment training program and Johnson’s relationship enrichm...

as igm and iga-enriched preparations are needed to complete the immunotherapeutic spectrum, a simple procedure is described for the preparation of igm and iga enriched immunoglobulins. fraction iii which was prepared by cold ethanol fractionation was treated by octanoic acid followed by ethanol precipitation and ion-exchange chromatography using sephadex deae a-50 and 0.1 m tris-d.35m naci buff...

in this study the optimal amount of enriching artemia franciscana with a synbiotic combination of pediococcus acidilactici and fructooligosaccharide (fos( was investigated. the experiment was conducted in a completely randomized design in ten treatments: multi-level probiotics p. acidilactici (1×109, 1×108 and 1× 107 cfu per l) and multi-level enriched prebiotic fos (1, 2 and 5) g per l of solu...

background: platelet preparations have been used for a wide variety of clinical applications such as hemorrhage, tissue engineering and cellular therapy. platelet concentrates can be prepared by the apheresis method or from the whole blood using the buffy-coat or platelet-rich plasma methods. the purpose of this study was to compare four variations of platelet-rich plasma method based on double...
