The present study investigated the relationship between the reading comprehension and information processing strategies of relatively fluent oral readers of Oriya orthography. The study was necessary, because Oriya orthography has some significant differences from English orthography and these differences could bear implications for the reading strategies and processes. Hence, it was envisaged that findings in the field of reading research using English orthography may not hold good for the readers of Oriya orthography. One hundred students of grade V were taken as subjects in the present study. Reading comprehension tasks simultaneous and successive information processing tasks and a nonverbal measure of intelligence were administered to all the subjects. Results show that good comprehenders were relatively more intelligent than the poor comprehenders. So far as their performance on simultaneous and successive information processing strategies were concerned good cornprehenders were better off on both types of coding tasks and these differences were found to be statistically significant even after the effect of intelligence was partialled out. However, no differential proficiency on either of these coding strategies was observed neither for the good nor for the poor comprehender group.  相似文献

Cross-lingual semantic interoperability has drawn significant attention in recent digital library and World Wide Web research as the information in languages other than English has grown exponentially. Cross-lingual information retrieval (CLIR) across different European languages, such as English, Spanish, and French, has been widely explored; however, CLIR across European languages and Oriental languages is still in the initial stage. To cross language boundary, corpus-based approach is promising to overcome the limitation of the knowledge-based and controlled vocabulary approaches but collecting parallel corpora between European language and Oriental language is not an easy task. Length-based and text-based approaches are two major approaches to align parallel documents. In this paper, we investigate several techniques using these approaches and compare their performances in aligning English and Chinese titles of parallel documents available on the Web.  相似文献

The vital task of the libraries attached to the educational institutions of higher learning is the collection development of information resources as per the requirements of the users. The Central Library of IITs have long been recognized their responsibility to support the study and research of their parent institutions with the rich collection development of information resources both in print as well as electronic format to cater the needs of the academic communities as per the multi-disciplinary and diverse academic program of the respective institutions where greater emphasis on collection of serials, the essential and integral component of updated scholarly communication. The study provides a vivid picture about the current status of serials collection in the libraries attached to the Premier Institutions of India in the field of science and technology to boost up the academic performances.  相似文献

The rate of glucose consumption and pyruvate and lactate production in red blood cells of normal, sickle cell trait and SS disease subjects were measured. Glucose consumption was found to be increased significantly (p<0.05) in red cells of sickle cell patients than the sickle cell trait and normal persons. There was also an increased rate (p<0.05) of pyruvate formation and a significant (p<0.05) increase in lactate formation in sickle red cells.  相似文献

The world of mobile communications is poised for yet another disruptive transformation – the introduction of 5G. It will change the way mobile phones communicate. New technologies at the device level and novel network architectures to manage them will be soon seen everywhere. This article explores what 5G is all about. It also talks briefly about the preparations underway across the globe to deploy 5G by 2020.  相似文献

With the fast development of acoustic systems in clinical and therapeutic applications, acoustically driven microbubbles have gained a prominent role as powerful tools to carry, transfer, direct, and target drug molecules in cells, tissues, and tumors in the expanding fields of targeted drug delivery and gene therapy. The aim of the present study is to establish a biocompatible acoustic microfluidic system and to demonstrate the generation of an acoustic field and its effects on microbubbles and biological cells in the microfluidic system. The acoustic field creates non-linear oscillations of the microbubble-clusters, which results in generation of shear stress on cells in such microsystems. This effectively helps in delivering extracellular probes in living cells by sonoporation. The sonoporation is investigated under the combined effects of acoustic stress and hydrodynamic stress during targeted drug and gene delivery.  相似文献

This study aims to elucidate the antiproliferative mechanism of hydroxychavicol(HC).Its effects on cell cycle,apoptosis,and the expression of c-Jun N-terminal kinase(JNK)and P38 mitogen-activated protein kinase(MAPK)in HT-29 colon cancer cells were investigated.HC was isolated from Piper betle leaf(PBL)and verified by high-performance liquid chromatography(HPLC),nuclear magnetic resonance(NMR),and gas chromatography-mass spectrometry(GC-MS).The cytotoxic effects of the standard drug 5-fluorouracil(5-FU),PBL water extract,and HC on HT-29 cells were measured after 24,48,and 72 h of treatment.Cell cycle and apoptosis modulation by 5-FU and HC treatments were investigated up to 30 h.Changes in phosphorylated JNK(pJNK)and P38(pP38)MAPK expression were observed up to 18 h.The half maximal inhibitory concentration(IC50)values of HC(30μg/mL)and PBL water extract(380μg/mL)were achieved at 24 h,whereas the IC50of 5-FU(50μmol/L)was obtained at 72 h.Cell cycle arrest at the G0/G1 phase in HC-treated cells was observed from12 h onwards.Higher apoptotic cell death in HC-treated cells compared to 5-FU-treated cells(P<0.05)was observed.High expression of pJNK and pP38 MAPK was observed at 12 h in HC-treated cells,but not in 5-FU-treated HT-29 cells(P<0.05).It is concluded that HC induces cell cycle arrest and apoptosis of HT-29 cells,with these actions possibly mediated by JNK and P38 MAPK.  相似文献

We discuss the aspects of non-locality and nonseparability of states of composite quantum systems. The probabilistic nature of quantum mechanical predictions, and the impossibility of cloning, are shown to safeguard causality in the quantum world. An example of a game which can be won exploiting quantum entanglement, but which can never be won classically, is described.  相似文献

We discuss the significance of Einstein’s second postulate of the special theory of relativity (STR) stipulating the constancy of the speed of light in vacuum. The causality that follows from the STR may be a more general principle to organize our knowledge of all phenomena. In particular, quantum dynamics can be derived using the causality principle. Causality does not prohibit quantum mechanics to be non-local, and this has implications in the real world.  相似文献
