The Hill

The present paper aims to throw light on the environmental sensitivity illustrated through art on a hill signifying interface of nature and culture .Ayodhya Hill in Purulia district, displays an aspect of aesthetic attachment of humans with nature in the form of in-situ rock cut sculpture ‘Pakhi Pahar’which has transformed the bare hill into a piece of art. For the past three decades the hill has been sculpted by a group of local artists, creating around 65 birds.Even the boulders lying on the foot of the hill are sculpted, to save these fragile components of nature from stone quarrying and crushing machines which are demolishing and fragmenting the rocks and hills of the chotanagpur terrain to gather stone chips for commercial use. It may also be argued by a few ,that the natural environment of Matha range of Ayodhya Hill is infringed upon for the sake of art. The present researcher seeks to explain through empirical observation, narrative analysis and perception study of local people whether Pakhi Pahar is an “Aesthetic Regard” or “Aesthetic Affront” for nature . This paper also tries to bring in to focus the future potential of this cultural landscape in developing as a tourism site and giving employment to the local youth.

Indigenous Heritage

<p>This thesis aims to understand how indigenous heritage values might be represented in post-colonial urban environments. Using an urban design and landscape architecture lens, this paper builds on an emerging body of heritage knowledge in an attempt to recognize the contrasts between western and indigenous heritage values.  Through the study of a selection of indigenous landscape precedents from America, Canada, South Africa and New Zealand, common representational trends of heritage design are identified. These examples illustrate some of the issues that arise when landscapes of indigenous significance are presented within a western heritage framework.  The documents, Tapuwae and Te Aranga: Māori Cultural Landscape Strategy are introduced as guides to Māori intangible heritage. These guides are discussed in relation to the New Zealand urban design and heritage discourse. Contemporary outcomes of this current heritage climate include Waitangi Park and Pipitea pa. These are discussed and found to possess a number of values contributing to a positive approach to indigenous heritage design within Wellington’s challenging urban environment.  To continue this discussion, 39 Taranaki Street becomes the site of a design exploration. In 2005, three ponga (silver tree fern) whare (houses) of Te Aro pa, were unearthed on this site. The whare are the only known physical trace of the Taranaki whānui’s pa (village), which stood from 1835 to 1902. The whare are currently preserved in-situ as part of an apartment complex. The design concept is to link the past layers to the current and future development of the site and its precinct in order to celebrate the close connection between the past and the present that intangible heritage practices facilitate.</p>

Studies of the nature of a surface, either metallic or nonmetallic, in the past, have been limited to the instrumentation available for these measurements. In the past, optical microscopy, replica transmission electron microscopy, electron or X-ray diffraction and optical or X-ray spectroscopy have provided the means of surface characterization. Actually, some of these techniques are not purely surface; the depth of penetration may be a few thousands of an inch. Within the last five years, instrumentation has been made available which now makes it practical for use to study the outer few 100A of layers and characterize it completely from a chemical, physical, and crystallographic standpoint. The scanning electron microscope (SEM) provides a means of viewing the surface of a material in situ to magnifications as high as 250,000X.

Data Result

Inorganic particulate material of diverse types is present in the ambient and occupational environment, and exposure to such materials is a well recognized cause of some lung disease. To investigate the interaction of inhaled inorganic particulates with the lung it is necessary to obtain quantitative information on the particulate burden of lung tissue in a wide variety of situations. The vast majority of diagnostic and experimental tissue samples (biopsies and autopsies) are fixed with formaldehyde solutions, dehydrated with organic solvents and embedded in paraffin wax. Over the past 16 years, I have attempted to obtain maximal analytical use of such tissue with minimal preparative steps. Unique diagnostic and research data result from both qualitative and quantitative analyses of sections. Most of the data has been related to inhaled inorganic particulates in lungs, but the basic methods are applicable to any tissues. The preparations are primarily designed for SEM use, but they are stable for storage and transport to other laboratories and several other instruments (e.g., for SIMS techniques).

Potential Use

The properties of metal/semiconductor interfaces have received considerable attention over the past few years, and the Al/GaAs system is of special interest because of its potential use in high-speed logic integrated optics, and microwave applications. For such materials a detailed knowledge of the geometric and electronic structure of the interface is fundamental to an understanding of the electrical properties of the contact. It is well known that the properties of Schottky contacts are established within a few atomic layers of the deposited metal. Therefore surface contamination can play a significant role. A method for fabricating contamination-free interfaces is absolutely necessary for reproducible properties, and molecularbeam epitaxy (MBE) offers such advantages for in-situ metal deposition under UHV conditions

Future Potential

In 2016, the United Nations (UN) launched the Digital Blue Helmets (DBH) program under its Office of Information and Communications Technologies (OICT). The launching of DBH was a continuation of a series of steps that the UN and its related agencies and departments have undertaken over the past decade to incorporate cyberspace within their working methodologies. At the time of inception, DBH was envisioned as a team capacitated to act as a replica of a physical peacekeeping force but for the sole purpose of overseeing cyberspace(s). Several research studies have been published in the past few years, which have conceptualized cyber peacekeeping in various ways. Some scholars have mentioned DBH as a starting point of cyber peacekeeping while some have proposed models for integration of cyber peacekeeping within the current UN peacekeeping architecture. However, no significant study has attempted to look at how DBH has evolved since its inception. This research article aims to examine the progress of DBH since its formation. It argues that despite four years since its formation, DBH is still far away from materializing its declared objectives. The article also discusses the future potential roles of DBH, including its collaboration with UN Global Pulse for cyber threat detection and prevention, and embedding the team along with physical peacekeepers.

If Hedley Bull came back today and revised his most famous book, he would likely devote a chapter to the economic forces that transformed our world during the past four decades. Among other systemic changes, the radical unleashing of finance and the partial return of a pre-1914 economic ideology justifying open and integrating capital markets might surprise an advocate of the virtues of the states system. But by following Bull’s reasoning, his model of empirical observation, and his underlying moral sensibilities—as well as suggestions from his constructive critics—this essay traces the emergence since the late 1970s of a variegated global capacity to assess systemic financial risks, design collaborative policies to prevent systemic crises, and manage them when they nevertheless occur. The challenge of deeply legitimating that nuanced and complex capacity remains, which, as Bull anticipated, means that considerations of justice must soon be addressed.

Over the past decades, a number of bone tissue engineering (BTE) approaches have been developed to address substantial challenges in the management of critical size bone defects. Although the majority of BTE strategies developed in the laboratory have been limited due to lack of clinical relevance in translation, primary prerequisites for the construction of vascularized functional bone grafts have gained confidence owing to the accumulated knowledge of the osteogenic, osteoinductive, and osteoconductive properties of mesenchymal stem cells and bone-relevant biomaterials that reflect bone-healing mechanisms. In this review, we summarize the current knowledge of bone-healing mechanisms focusing on the details that should be embodied in the development of vascularized BTE, and discuss promising strategies based on 3D-bioprinting technologies that efficiently coalesce the abovementioned main features in bone-healing systems, which comprehensively interact during the bone regeneration processes.
