Structural and magnetic properties of Co-N thin films deposited using magnetron sputtering at 523 K

In this work, we studied cobalt nitride (Co-N) thin films deposited using a dc magnetron sputtering method at a substrate temperature (Ts) of 523 K. We find that independent of the reactive gas flow (RN2 ) used during sputtering, the phases of Co-N formed at this temperature seems to be identical having N at.% ∼ 5. This is contrary to Co-N phases formed at lower Ts. For example at Ts∼ 300 K, an ev

Vitamin D action and regulation of bone remodeling : suppression of osteoclastogenesis by the mature osteoblast

UNLABELLED: Vitamin D acts through the immature osteoblast to stimulate osteoclastogenesis. Transgenic elevation of VDR in mature osteoblasts was found to inhibit osteoclastogenesis associated with an altered OPG response. This inhibition was confined to cancellous bone. This study indicates that vitamin D-mediated osteoclastogenesis is regulated locally by OPG production in the mature osteoblast.

Changing RANKL/OPG mRNA expression in differentiating murine primary osteoblasts

Osteoblast-osteoclast coordination is critical in the maintenance of skeletal integrity. The modulation of osteoclastogenesis by immature cells of the osteoblastic lineage is mediated through receptor activator of NF kappa B (RANK), its ligand RANKL, and osteoprotegerin (OPG), a natural decoy receptor for RANKL. Here, the expression of OPG and RANKL in primary mouse osteoblastic cultures was inves

City identities and cultural memories : A digital ethnography of the poetics and politics of participatory cultures in Southeast Asian cities

This paper is based on the preliminary stage of a PhD research that aims to explore meaning of cultural memories and its relation to the notion of city identities from participatory cultures that occur in Southeast Asian cities. The paper discusses the development of its conceptual framework, from cultural memory studies, participatory cultures in urban context, to digital ethnography as the resea

Indonesia has been officially joining "the global family" of Spotify since late of March 2016. How is the impact of this new media phenomenon on the landscape of auditory media in Indonesia? Also, how are the challenges being faced on media studies in the Indonesian contexts?

Surrounded by Images and Meanings : Essays on Media and Cultural Studies

This book consists of seventeen essays which are categorised into four sections: (1) the theoretical standpoint: semiotic and discursive approach, (2) news photography, television, and Internet in particular context, (3) cinema in contexts, and (4) documentary studies. The topics being discussed in all essays are varied, ranging from media in Asia, film and documentary studies, media and social ac

Participatory as everyday life : From creativity-based initiative to the production of networked space in Southeast Asian cities

The notion of creative city has been extensively discussed both in academic debate as well as public discourse, including on Asian context. However, a tendency to study only on strategic government policies in relation to this matter has led many multi-dimensional aspects being left behind. One of these important aspects is the creativity-based activities initiated and conducted by local groups, c

Modeling and Estimation Topics in Robotics

The field of robotics offers a wide array of estimation problems, ranging from kinematic and dynamic calibration to pose estimation and computer vision. This thesis presents a set of methods to solve estimation problems encountered in robotics, with an emphasis on industrial robotics. The researched topics are all practically motivated and have found immediate use in applications.Industrial roboti

Fear of falling, falls and near falls in Parkinson’s disease

ABSTRACTAIM: The overall aim of this longitudinal PhD project was to gain increased knowledge about factors associated with fear of falling (FOF) falls and near falls, as well as to contribute to improved clinical fall prediction for peoplewith mild Parkinson’s disease (PD).METHODS: People diagnosed with PD and receiving care at the university hospital outpatient neurology clinic were assessed dur

Crystal structure of β-glucosidase 1A from Thermotoga neapolitana and comparison of active site mutants for hydrolysis of flavonoid glucosides

The β-glucosidase TnBgl1A catalyses hydrolysis of O-linked terminal β-glycosidic bonds at the nonreducing end of glycosides/oligosaccharides. Enzymes with this specificity have potential in lignocellulose conversion (degrading cellobiose to glucose) and conversion of bioactive flavonoids (modification of glycosylation results in modulation of bioavailability). Previous work has shown TnBgl1A to hy
