Eosinophil Degranulation

Eosinophils are specialized white blood cells, which are involved in the pathology of diverse allergic and nonallergic inflammatory diseases. Eosinophils are traditionally known as cytotoxic effector cells but have been suggested to additionally play a role in immunomodulation and maintenance of homeostasis. The exact role of these granule-containing leukocytes in health and diseases is still a matter of debate. Degranulation is one of the key effector functions of eosinophils in response to diverse stimuli. The different degranulation patterns occurring in eosinophils (piecemeal degranulation, exocytosis and cytolysis) have been extensively studied in the last few years. However, the exact mechanism of the diverse degranulation types remains unknown and is still under investigation. In this review, we focus on recent findings and highlight the diversity of stimulation and methods used to evaluate eosinophil degranulation.

Boson Model

Single-particle level energies form a significant input in nuclear physics calculations where single-particle degrees of freedom are taken into account, including microscopic interacting boson model investigations. The single-particle energies may be treated as input parameters that are fitted to reach an optimal fit to the data. Alternatively, they can be calculated using a mean field potential, or they can be extracted from available experimental data, as is done in the current study. The role of single-particle level energies in the microscopic interacting boson model calculations is discussed with special emphasis on recent double beta decay calculations.

Despite its prominent place in the Occupational Therapy Guidelines for client-centred practice, the exact role of spirituality in clinical practice has been difficult to delineate. In this paper current concepts of spirituality are outlined and ways in which these concepts have been applied in health care are described. To illustrate these spiritual concepts, the experiences of individuals whom the authors have met in their clinical practice are outlined in a series of vignettes. Finally, a revision of the model of occupational performance which enhances consideration of spirituality in occupational therapy practice is proposed, and some guidelines for occupational therapists wishing to incorporate spiritual concerns in therapy are suggested.

Natural Philosophers

The paper aims to show how sixteenth century hydraulic and pneumatic engineers appropriated ancient science and technology – codified in the text of Hero of Alexandria’s Pneumatics – to enter into scientific discourse, for instance, with natural philosophers. They drew on the logical structure, content and narrative style passed down from antiquity to generate and codify their own theoretical approach and to document their new technological achievements. They did so by using the form of commented and enlarged editions, just as Aristotelian natural philosophers had been doing for centuries. The argument aims to detail the exact role of ancient science and the process of transformation it underwent during the early modern period. In particular, it aims to show how pneumatic engineers first tested the ancient technology codified by Hero while carrying out their own practical activities. Once these tests were successfully concluded, in the spirit of early modern humanism they finally presented these activities as being associated with the work of their discipline’s most authoritative author, Hero of Alexandria, whose technology was tested during the construction of the hydraulic and pneumatic system of the garden of Pratolino.

The Impact

The impact of phonon and their surrounding environment on exciton and its complexes were investigated in monolayer WSe2 semiconductor. Phonon up-conversion has been studied in past for conventional III–V semiconductors, but its role in two-dimensional layered transition metal dichalcogenides has rarely been explored. We investigated the photoluminescence up-conversion mechanism in WSe2 monolayer and found that a lower energy photon gain energy upto 64[Formula: see text]meV to be up-converted to emission photon at room temperature. Moreover, the phonon-exciton coupling mechanism has also been investigated and the role of dielectric screening has been explored to get complete insight of coulomb’s interaction in these electron-hole pairs. Investigations of charge carrier’s lifetime reveal that boron nitride encapsulated monolayer has shorter recombination time as low as 41 ps as compared to a bare monolayer on SiO2 substrate. These results are very promising for realizing spintronics-based application from two-dimensional layered semiconductors.
