The Potentials of Feicui : Indeterminacy and Determination in Human-Jade Interactions in South-West China

Based on fieldwork among jade traders and carvers in Ruili, this chapter discusses the realization of economic and spiritual potentials of a type of jade called feicui翡翠 as determination of a partially indeterminate material. Some traders posit feicui as an empty container for economic value, while the material constitutes spiritual fullness especially for carvers. An opaque layer of surface skin

A rotating-slit-collimator-based gamma radiation mapper

For situations with radioactive material out of control where it may be physically difficult or prohibited to access areas close to the source, measurements from distance may be the only way to assess the radiation environment. Using collimated detectors will provide means to locate the direction of the radiation from the source. To investigate the possibilities of mapping gamma emitting radioacti

Biopython Project Update 2017

The Biopython Project is a long-running distributed collaborative effort, supported by the Open Bioinformatics Foundation, which develops a freely available Python library for biological computation [1]. We present here details of the Biopython releases since BOSC 2016, namely Biopython 1.68, 1.69 and 1.70. Together these had 82 named contributors including 51 newcomers which reflects our policy o

Trade Liberalization and the Geography of Production : Agglomeration, Concentration and Dispersal in Indonesia’s Manufacturing Industry

The effect of the liberalization of trade on the spatial concentration of economic activities is not straightforward. It has been widely argued that protectionism increases spatial concentration as firms locate close to the main domestic markets. However, it has also been argued that an expansion of international trade primarily favors existing industrial centers and therefore leads to increased r

The Macroeconomic Effects of Banking Crises : Evidence from the United Kingdom, 1750-1938

This paper investigates the macroeconomic effects of UK banking crises over the period 1750 to 1938. We construct a new annual banking crisis series using bank failure rate data, which suggests that the incidence of banking crises was every 32 years. Using our new series and a narrative approach to identify exogenous banking crises, we find that industrial production contracts by 8.2 per cent in t

Circular Business Models : Defining a Concept and Framing an Emerging Research Field

To aid companies in transitioning towards a circular economy and adopting strategies such as reuse, repair, and remanufacturing, the concept of circular business models has been developed. Although the concept draws on contributions from various academic disciplines, and despite its increasingly frequent use, few scholars clearly define what a circular business model is. Understanding about what m

Serous retinal detachment after panretinal photocoagulation for proliferative diabetic retinopathy : A case report

Background: Proliferative diabetic retinopathy is a major cause of visual impairment in working-age adults worldwide. Panretinal photocoagulation is a cornerstone in its management; however, it may include a range of side effects and complications, one of these being serous retinal detachment. To the best of our knowledge, this is the first report of the use of intravitreal injection of bevacizuma

Technology Transfer and Spillovers : Does Local Participation with Multinationals Matter?

This paper examines the effects on technology transfer and spillovers deriving from ownership sharing of foreign multinational affiliates. More specifically, we try to answer two questions, using unpublished Indonesian micro data. Firstly, do establishments with minority and majority ownership differ in terms of productivity levels? Secondly, does the degree of spillover differ with the degree of

Hydroxyapatite granule/carrier composites promote new bone formation in cortical defects

BACKGROUND: A great deal of interest has been focused on finding substitutes for autogenous bone grafts. Among the most interesting materials are different calcium phosphate compositions (e.g., hydroxyapatite [HA]), due to their biocompatible properties in hard and soft tissue.PURPOSE: The bone response to porous ceramic HA granules in combination with two lipid and one polysaccharide carrier was

Immunohistochemical studies on the distribution of albumin, fibrinogen, fibronectin, IgG and collagen around PTFE and titanium implants

Time-dependent distribution of extracellular proteins (albumin, fibrinogen, fibronectin, collagen-I and IgG) in the interface zone between implant and soft tissue has been investigated utilizing a recently developed method. Commercially pure (c.p.) titanium and polytetrafluoroethylene (PTFE) implants were inserted in the abdominal wall of rats for 1, 6 and 12 weeks followed by a mild fixation, cry

Peripheral nerve regeneration in Gore-tex chambers

Gore-tex chambers were used to bridge a 6 mm gap between the proximal and distal nerve stumps of a rat sciatic nerve. The wall structure of these chambers is characterized by "nodes" interconnected by smaller fibrils. Chambers with internodal distances of 5, 10 and 30 microns were used. Some 30 microns chambers were coated from the outside with Gore-tex (0.2 micron internodal distance) and others

Nerve regeneration across an extended gap : a neurobiological view of nerve repair and the possible involvement of neuronotrophic factors

We have compared the anatomic and functional regeneration of a transected sciatic nerve following regrowth from its proximal stump through either preformed empty mesothelial chambers or autologous nerve grafts bridging a 10 mm gap. Within the mesothelial chambers an organized multifascicular nerve trunk forms between the proximal and distal stumps. After 3 months, distal segment cross sections fro

Sympatho-adrenergic inhibition of basal and acid-induced changes in duodenal motility, mucosal net fluid and alkaline secretion in the anaesthetized cat

Experiments were performed on chloralose anaesthetized cats. A 2-cm segment of the proximal duodenum was isolated between two luminally situated balloons and perfused with isotonic saline containing [14C]-PEG 4000 as a non-absorbable marker. The perfusate was analysed with regard to alkalinity (back titration) and concentration of marker (liquid scintillation). Net alkalinization and net fluid tra
