It is important to understand the band offsets between semiconductors, which are crucial to determine the direction of electron transfer at the interfaces. Two methods are normally used to determine the direction from the first principles: alternating slabs put in contact (without empty spaces between them) and separate calculations for each material surface in the presence of vacuum spaces. The first method may introduce distortions due to insufficient epitaxial match, which may lead to bandgap changes, and the se [...]

Background:Fluorescence in situ hybridization (FISH) can be performed on metaphase- and/or interphase cells. Metaphase cells can exclusively be obtained and studied after time-consuming cell culture. Therefore, this technique is suitable only for cells derived from peripheral blood, bone marrow or fibroblasts, the latter including skin, tumour or "prenatal tissues", such as the amnion or chorion. On the other hand, interphase cells can be gained from many different cells and even without cell culture. Methods:Here, [...]

After the emergence of Mindfulness in the Western world, many studies proved its mental and physical benefits. However, implementing Mindfulness in psychotherapy has several challenges: therapists are not formal Mindfulness instructors; the Mindfulness course is a continuous eight-week course, which many patients do not attend during therapy, while others attend and drop out. Thus, Hypnosis was applied to shorten and strengthen the desired changes. The article describes the logic behind this integration, demonstrat [...]

Mindfulness practices have exploded in popularity in public awareness and in therapeutic applications. While mindfulness in a therapeutic context is presented as a secular practice, its primarily Buddhist heritage may make some Christian clients wary of engaging. Research indicates that both reflection (co-creation) on poetry and creation of poetry can be therapeutic, and that both Buddhist and secular/therapeutic mindfulness texts use poetry to convey meaning through key themes of nature, change/impermanence, stag [...]

Lipase-catalyzed hydrolysis of olive oil has been studied in the absence of emulsifier. A simple mathematical model to predict the hydrolysis rate is derived from a proposed kinetic mechanism of the reaction. The hydrolytic reaction obeys Michaelis-Menten kinetics with a simultaneous second-order enzyme deactivation. The model predictions closely agree with the experimental results.

High-quality care is an important aim of palliative care services. However, the quality of care is a complex phenomenon and is subjectively perceived by those who are closest to the services and are often evaluated poorly. Prior research has highlighted the difficulties in evaluating the quality of care because of different perspectives, and still, only a little is understood about the perception of the quality of care in palliative care services. Investigating the perspectives of key individuals involved in pallia [...]
