Glocalisation of global market forces and the repositioning of a peripheral Russian mining community
No full textIncreasing globalisation and global market forces shape the development of resource peripheries in the Barents region. Foreign direct investments are concrete example of global market forces. Their glocalisation forces the locals to evaluate their consequences for the local development and reposition their communities in global context. This article studies glocalisation of global market forces and preferred directions of repositioning of a peripheral single-industry mining community in the Russian Barents region. The study is based on a case study of local opinions about actual and potential external actors in the economic development of Kovdor, located in the Murmansk region. The paper analyses the preferred owner of the town-constituting enterprise and the local opinions about the EU, USA and China as potential investors to the case study community. The study reveals how local opinions about external forces in the local development are related to local life-worlds. Moreover, the paper shows the impact that economic, political, cultural, historical and technological factors have in forming these opinions about potential foreign investors. The study shows generally positive local opinions about FDI. However, significant differences were found in opinions about different investing countries.publishedVersio
The evaluation of efficacy of three different ultrasonography methods for verification of gastric tube placement in intensive care unit patients
No full textGastric tube (GT) placement is a routine procedure in critically ill patients. Improper placement of GT could lead to severe complications. Radiography remains as the gold standard test to confirm tube position. The study aim is to estimate diagnostic accuracy of three different ultrasonography (USG) methods to verify GT placement in intensive care units (ICU).
Twenty-five mechanically ventilated patients were included in this prospective and observational study. All real time US examinations were performed by an intensivist in three steps: sonography ofneck for visualizing esophagus and upper abdominal quadrant for visualizing stomach,and visualisation of dynamic fogging during water and air insufflations in gastric area. Finally, gastric placement of GT was confirmed with abdominal radiography.
USG visualized GT in esophagus in 24 (96 %) patients. GT was directly visualized in stomach in 16 (64%) patients and dynamic fogging occurred in 20 (80 %) in the first attempt and in 23 (92 %) patients after tube removal. Because gastric tube was not seen in stomach in nine cases, dynamic fogging allowed to confirm intragastric position in seven cases. In two cases, no dynamic fogging was observed, and radiography confirmedtube malposition in esophagus. Entire sonographic procedure took 7.24±2.58 minutes.
Visualization of the esophagus and dynamic fogging improves the diagnostic accuracy of USG in verifying GT position. Confirming correct GT placement by USG has the potential to reduce X-ray usage and save time. However, X-ray remains the gold standard in cases in which USG cannot verify placement of the GT.

Preparation of ca-alginate biopolymer beads and investigation of their decorporation characteristics for 85Sr, 238U and 234Th by in vitro experiments
No full textThe aim of this work was to investigate whether Ca-alginate biopolymer beads (CaABBs) can be used to reduce the bioavailability of radionuclides in the gastrointestinal tract of humans. The uptake of strontium, uranium and thorium from a simulated gastrointestinal system was studied by invitro techniques using CaABBs. This agent was prepared from Na-alginate through cross-linking with divalent calcium ions according to the egg-box model. The effects of process variables such as pH of the gastrointestinal juice, incubation time and solid-to-solution ratio for the removal of radionuclides from the gastrointestinal juice were investigated. The results suggest that CaABBs are a potent material for reducing the bioavailability of radionuclides with a high uptake efficiency in the gastrointestinal tract.Copy; Author 2012.

Management of a patient with Opalski's syndrome in intensive care unit
No full textKey Clinical Message Opalski syndrome is a rare vascular brainstem syndrome which is accepted as a variant of Wallenberg syndrome. Opalski syndrome should be considered in acute conditions in which typical symptoms of lateral medullary infarct are accompanied by ipsilateral hemiparesis. Other brain stem syndromes are distinguished from Opalski syndrome by the presence of contralateral hemiparesis

Survey of aflatoxin B-1 in helva, a traditional Turkish food, by TLC
No full textWOS: 000240869200011A total of 102 helva samples consisting of 34 plain helva, 34 helva containing cacao, and 34 helva containing pistachio nuts purchased from helva-factories and supermarkets in Adana of Turkey were analysed for aflatoxin B-1 (AFB(1)) by thin-layer chromatography. The detection limit of AFB(1) was 1 mu g kg(-1). Recovery experiments were carried out with spiked samples in the range 2-10 mu g kg(-1) of AFB(1). No AFB(1) was found in any plain helva and helva containing cacao samples. On the other hand, of 34 helva containing pistachio nuts AFB(1) was determined in eight samples. AFB(1) was found in excess of Turkish legal limit of 5 mu g kg(-1) in 4 of 102 helva samples. This paper reports the data of the first survey for the presence of AFB(1) in helva in Turkey.

The Effect of Different Harvest Times on Phenolic Content and Antioxidant Activity in Some Microgreens
No full textMicrogreens, which have only become popular during the last decades, are rich in phytochemicals, including phenolic compounds, which act as antioxidants. The study aimed to examine the effects of two different harvest times (cotyledon [embryonic leaves] and 1.5 -true leaf stage) of five microgreens on the bioactive compounds in terms of antioxidant capacity and total phenolics. The total phenolic components ranged from 60.9 to 2153.2 mg GAE g-1 in cotyledon leaves, whereas the value varied from 96.2 to 2113.9 mg GAE g-1 in the true leaves of microgreens. Increases in the phenolic content of the first true leaves in dill and chia were detected as 57.8% and 29.6% compared to the cotyledon leaf. Among the cotyledon microgreens, the maximum phenolic content was detected in the garden cress. The antioxidant capacity of the cotyledon and true leaf stages ranged between 485.4 +/- 2.3-1985.67 +/- 24.9 mu g g-1 and 508.87 +/- 5.3-2393.56 +/- 12.6 mu g g-1, respectively. The maximum antioxidant capacity was detected in radish, followed by garden cress. The biggest variation between the cotyledon and first true leaves in the study was observed for red beetroot. This study revealed the alteration in the phenolic content and antioxidant activity of five cultivars based on growth stages of cotyledonary and true leaves in microgreen form

Determinants for Use of Certified Maize Seed and the Relative Importance of Transaction Costs
No full textThe rising world prices for major tradable staples such as maize have been a concern for sub- Saharan countries such as Kenya which are maize deficit countries. Maize is a major staple food for over 80 percent of Kenya’s population. Kenya relies on maize for up to 40 percent of its dietary energy supply and is accordingly searching for ways to increase maize productivity. Maize productivity has been rising in the last decade manly as a result of the use of improved germplasm and fertilizer. However, the proportion of farmers using these technologies is low and the aggregate productivity in maize is low compared to other countries and its potential. Previous studies on input adoption have often assumed the existence of perfect supply and product markets, tending to ignore the important but significant role played by institutions as well as the role of transaction costs associated with market exchange. This study makes use of qualitative information from institutions and actors in seed input value chains as well as quantitative information collected from a sample of 150 farmers, in the Moist Transitional Maize Zones of Kenya. A two stage regression model was applied to analyze determinants of adoption and factors affecting degree of adoption of certified improved maize seed. The results show that as farmers adopt certified seeds, they incur higher transaction costs than non adopters, rural infrastructure, social capital such as membership in groups and trust play an important role in the decision of whether or not to use certified seed.Crop Production/Industries,
