The goal of this study was to determine the stability of Total Prostrate Specific antigen (PSA-T) and Free Prostrate Specific
Antigen (PSA-F) in archival serum stored at 4°C and −20°C and subjected to temperature shift due to interruption in power
supply. Our study showed that PSA-T was stable up to 285 days and PSA-F was stable for 158 days under these conditions. Since
power supply interruption is an unavoidable problem in developing nations, our study has implication on the validity of measurement
of PSA-T and PSA-F in serum that was not properly stored due to emergency situations and for certain types of retrospective
studies. 相似文献

Starting in the 1990s, the Caribbean two-island nation of Trinidad and Tobago witnessed the establishment of several Indian-music format radio stations, most of which now stream their content on the World Wide Web or otherwise make their content available beyond the range of their terrestrial radio transmitters. The convergence of traditional terrestrial radio with audio streaming technology combined with the spread of high speed broadband connections has expanded the audience of a typical radio station from a few kilometers to a globally dispersed set of listeners who often include those physically displaced from their native cultural programming. The present investigation examines the Facebook comments of domestic and foreign listeners to Indian-music format radio stations from the Republic of Trinidad and Tobago. 相似文献

In order to obtain maximum benefits from the educational system, it is imperative that the system should work as a unified coherent unit. Gaad, Arif and Scott (2006) conducted the systems analysis of the United Arab Emirates' (UAE) general education system. They analysed three components of the system in order to assess the development, delivery and evaluation. This paper utilises the same framework to analyse the special needs education (SEN) system in the UAE. Data for the research were collected through observations and semi-structured interviews. Analysis of the data identifies some possibilities for improvement. In the area of development, more teaching and supplemental material specific to special needs education needs to be developed. Currently, teachers are working with what is known as the 'para curriculum'. It is based on the regular textbook; with chapters that are difficult being simplified or removed. In the area of delivery, more training would be beneficial to teachers. The monitoring and evaluation component's analysis points out that the evaluation instrument used currently needs to be modified for special needs education monitoring and additional resources in the area of special needs education would required. 相似文献

ABSTRACT Athlete Biological Passport (ABP) is an indirect approach, implemented by WADA, aimed at detecting blood manipulation based on abnormal changes in haematological markers. Cases report the use of hyperhydration as masking method during anti-doping urine sample collection which could potentially mask suspicious fluctuations on ABP profiles. This study investigated the hyperhydration effect on haemoglobin concentration, reticulocyte percentage and OFF-hr score (an algorithm based on haemoglobin concentration and reticulocyte percentage), with and without recombinant human erythropoietin (rHuEPO) administration. A five-week clinical study performed; Baseline and rHuEPO Phase. Water and a sports drink were used as hyperhydration agents. To examine the hyperhydration effect on the normal ABP profile per volunteer, hyperhydration was implemented at 0, 24 and 48 hours during the baseline. During the rHuEPO phase, volunteers received Epoetin beta (3000 IU) with hyperhydration to be implemented at 0, 24 and 48 hours after drug administration. Blood and urine samples were collected and analysed according to WADA guidelines. No significant effect on ABP markers was observed due to hyperhydration at any time during the study. Pre- and post-hyperhydration data were not statistically different compared to individual baseline data. In conclusion, hyperhydration does not affect the ABP haematological markers under the examined conditions. 相似文献

This paper explores the higher education financing policy in Morocco in light of the central issue of equity. First, it surveys
the current situation, using a critical approach to the present financing policy, and looking at the three dimensions of adequacy,
efficiency, and equity. Second, it describes the principal policy challenges in financing higher education. Third, it presents
several public policy proposals likely to bring changes to the financing policy in order to meet these challenges. The analysis
shows that the sustainability and the equity of the current financing system are undermined by the dysfunctions introduced
by the private/public split in the higher education system and the lack of a clear political strategy pertaining to the medium
of instruction. 相似文献

The pun is a tricky use of a word or phrase which has very different meanings that are closely interrelated, or of words with the same sound but different meanings. The Pun is a term with a dual meaning: “close” using obvious reference, and “far” using obscure reference. The hidden is usually meant. The close meaning is the sooner that comes to the listener’s mind. However, the speaker targets at the far one yet use the close to hide it. Translating the Quran text always raises several serious challenges in translation; these challenges are due to the different translations of puns and the misinterpretations between the intended meanings of a pun with their basic concepts, which could result in a certain amount of ambiguity. The study examines the Quranic corpus and its three versions of English translations. The study utilizes the typology of Delabastita?s for horizontal puns, Nida’s techniques of dynamic and formal equivalent and Newmark’s translation methods. This research attempts to investigate the semantic meaning of puns in the Quran translation and to define the translation techniques applied in translating the Quranic puns from Arabic into English. 相似文献

Text Categorization (TC) is the automated assignment of text documents to predefined categories based on document contents. TC has been an application for many learning approaches, which prove effective. Nevertheless, TC provides many challenges to machine learning. In this paper, we suggest, for text categorization, the integration of external WordNet lexical information to supplement training data for a semi-supervised clustering algorithm which can learn from both training and test documents to classify new unseen documents. This algorithm is the Semi-Supervised Fuzzy c-Means (ssFCM). Our experiments use Reuters 21578 database and consist of binary classifications for categories selected from the 115 TOPICS classes of the Reuters collection. Using the Vector Space Model, each document is represented by its original feature vector augmented with external feature vector generated using WordNet. We verify experimentally that the integration of WordNet helps ssFCM improve its performance, effectively addresses the classification of documents into categories with few training documents and does not interfere with the use of training data. 相似文献
