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

Now a days measurement of molecular forms of PSA has gained importance in clinical practice. Several studies have demonstrated
the production of PSA in female tissues, such as breast. The present piece of work has been undertaken with an objective to
estimate the relative proportion of the molecular forms of PSA in serum along with serum testosterone in benign and malignant
breast tumor cases and to analyze their association with the severity of the disease process 34 malignant and 26 benign breast
disease cases along with 33 healthy controls of same age group were enrolled in this study for evaluation. Serum testosterone
was measured by ELISA, whereas serum total PSA (TPSA) and free PSA (FPSA) were estimated by electrochemiluminescence immunoassay.
A significant rise of fasting plasma glucose along with prominent dyslipidemia was observed in breast tumor cases. Marked
rise in serum testosterone as well as TPSA and FPSA was documented in both benign and malignant breast tumor cases. Serum
testosterone revealed a significant positive association with both TPSA and FPSA pointing towards an etiological association
between them. However, surgical removal of tumor mass resulted in a marked decline of presurgical value of both TPSA and FPSA
with a non-significant fall in serum testosterone revealing tumor tissue as the source of FPSA and TPSA. Thus, estimation
of PSA provides prognostic information that may assist in future treatment. 相似文献

This paper presents the design and performance analysis of Proportional Integral Derivate (PID) controller for an Automatic Voltage Regulator (AVR) system using recently proposed simplified Particle Swarm Optimization (PSO) also called Many Optimizing Liaisons (MOL) algorithm. MOL simplifies the original PSO by randomly choosing the particle to update, instead of iterating over the entire swarm thus eliminating the particles best known position and making it easier to tune the behavioral parameters. The design problem of the proposed PID controller is formulated as an optimization problem and MOL algorithm is employed to search for the optimal controller parameters. For the performance analysis, different analysis methods such as transient response analysis, root locus analysis and bode analysis are performed. The superiority of the proposed approach is shown by comparing the results with some recently published modern heuristic optimization algorithms such as Artificial Bee Colony (ABC) algorithm, Particle Swarm Optimization (PSO) algorithm and Differential Evolution (DE) algorithm. Further, robustness analysis of the AVR system tuned by MOL algorithm is performed by varying the time constants of amplifier, exciter, generator and sensor in the range of ?50% to +50% in steps of 25%. The analysis results reveal that the proposed MOL based PID controller for the AVR system performs better than the other similar recently reported population based optimization algorithms. 相似文献

Solitons emerge as non-perturbative solutions of non-linear wave equations in classical and quantum theories. These are non-dispersive
and localised packets of energy — remarkable properties for solutions of non-linear differential equations. In the presence
of such objects, the solutions of Dirac equation lead to the curious phenomenon of ‘fractional fermion number’. Under normal
conditions the fermion number takes strictly integral values. In this article, we describe this accidental discovery and its
manifestation in polyacetylene chains, which has led to the development of organic conductors.

Practitioner notes
What is already known about this topic- University transitions to online learning during the Covid-19 pandemic were undertaken by faculty and students who had little online learning experience.
- The transition to online learning was often described as having a negative influence on students' learning experience and mental health.
- Varieties of cognitive load are known predictors of effective online learning experiences and satisfaction.
- Information overload and perceptions of technical abilities are demonstrated to predict students' difficulty and satisfaction with online learning.
- Students express negative attitudes towards factors that influence information overload, technical factors, and asynchronous course formats.
- Communication quantity was not found to be a significant factor in predicting either perceived difficulty or negative attitudes.
- We identify ways that educators in higher education can improve their online offerings and implementations during future disruptions.
- We offer insights into student experience concerning online learning environments during an abrupt transition.
- We identify design factors that contribute to effective online delivery, educators in higher education can improve students' learning experiences during difficult periods and abrupt transitions to online learning.

The study explores the publication trends of scholarly journal articles in two core Library and Information Science (LIS) journals indexed under ScienceDirect Database during the period for the period 2000–2010, and for the “Top 25 Hottest Papers” for 2006–2010. It examines and presents an analysis of 1000 research papers in the area of LIS published in two journals: The International Information & Library Review (IILR) and Library & Information Science Research (LISR). The study examines the content of the journals, including growth of the literature, authorship patterns, geographical distributions of authors, distribution of papers by journal, citation pattern, ranking pattern, length of articles, and most cited authors. Collaboration was calculated using Subramanyam's formula, and Lotka's law was used to identify authors' productivity. The results indicated that authors' distributions did not follow Lotka's law. The study identified the eight most productive authors with a high of 19 publications in this field. The findings indicate that these publications experienced rapid and exponential growth in literature production. The contributions by scientists from India are examined. 相似文献

The levels of norepinephrine (NE), dopamine (DA) serotonin (5-HT) and its metabolite 5-hydroxyindole acetic acid (5-HIAA)
have been determined in the cerebrospinal fluid (CSF) of normal (n=25) and suicidal attempt cases (n=30). A significant decrease
in the level of NE (p<0.01), 5-HT(p<0.001) and 5-HIAA (p<0.001) in the CSF of suicide attempt cases were observed as compared
to normal controls. It is concluded that CSF 5-HIAA level which is drastically depleted may be used as an early biochemical
indicator of suicidal attempt so that it may be treated by the drugs which can enhance the suppressed neurotransmitter activity. 相似文献

Current recommendations of the Adult Treatment Panel and Adolescents Treatment Panel of National Cholesterol Education Program
make the low-density lipoprotein cholesterol (LDL-C) levels in serum the basis of classification and management of hypercholesterolemia.
A number of direct homogenous assays based on surfactant/solubility principles have evolved in the recent past. This has made
LDL-C estimation less cumbersome than the earlier used methods. Here we compared one of the direct homogenous assays with
the widely used Friedewald’s method of estimation of LDL-C to see the differences and correlation. We used direct homogenous
assay kit to estimate serum LDL-C and high-density lipoprotein cholesterol (HDL-C). Serum Triglyceride (TG) and Total Cholesterol
(TC) was estimated and using Friedewald’s formula LDL-C was calculated. The LDL-C level obtained by both methods in 893 fasting
serum samples were compared. The statistical methods used were paired t-test and Pearson’s correlation.
There was significant difference in the mean LDL-C levels obtained by the two methods at the TG levels <200 mg/dl (p<0.02)
and TC levels >150 mg% (p<0.001). The correlation coefficient (r) between Friedewald’s and direct assay estimation was 0.88.
Friedewald’s method classified 23.5 % of patients as high cardiac risk whereas there were 17.58% by direct assay.
Both had good correlation even though the serum triglyceride and total cholesterol levels affect the difference in LDL-C estimated
by both methods. Taking into account the cost and performance, Friedewald’s method is as good or even better for classifying
and managing patients. 相似文献

Hooker (1882) has reported three varieties in Bidens pilosa species i. e., pilosa
Proper, Linn. bipinnata Linn. and decomposita Wall. Clarke (1876) has included
var. decomposita into B. pilosa proper. Taxonomic position of varieties pilosa proper
and bipinnata is much confusing in literature. Babu (1977)has raised varieties pilosa
proper and bipinnata as distinct species level into B. pilosa and B. bipinnata
respectively. The present taximetric study also justified the distinction of these varieties
as specific level.
Hooker has reported three varieties of species B. pilosa i.e., pilosa proper Linn.,
bipinnata Linn., and decomposita Wall. from the Himalayan region of India. Clarke
(1876) has included var. decomposita into B. pilosa proper. During taxonomic work on
the family Compositae author has found that taxonomic position of var. pilosa proper
and bipinnata is much confusing in literature. Babu (1977) has raised varieties pilosa
proper and bipinnata as distinct species level. Looking to this discretion, it was de-eided to use taximetrics in interpreting taxonomic status of these taxa. 相似文献

Ocimum sanctum Linn. (also known as Tulsi) is a sacred Indian plant, the beneficial role of which, in obesity and diabetes is described traditionally. This is a randomized, parallel group, open label pilot study to investigate the effect of O. sanctum on metabolic and biochemical parameters in thirty overweight/obese subjects, divided into two groups A and B. Group A (n = 16) received one 250 mg capsule of Tulsi (O. sanctum) extract twice daily in empty stomach for 8 weeks and group B (n = 14) received no intervention. Statistically significant improvements in the values of serum triglycerides (p = 0.019); low density lipoprotein (p = 0.001); high density lipoprotein (p = 0.001); very low density lipoprotein (p = 0.019); Body Mass Index, BMI (p = 0.005); plasma insulin (p = 0.021) and insulin resistance (p = 0.049) were observed after 8 weeks in the O. sanctum intervention group. The improvement in HDL-C in the intervention group when compared to the control group was also statistically significant (p = 0.037). There was no significant alteration of the liver enzymes SGOT and SGPT in both the intervention (p = 0.141; p = 0.074) and control arms (p = 0.102; p = 0.055) respectively. These observations clearly indicate the beneficial effects of O. sanctum on various biochemical parameters in young overweight/obese subjects. 相似文献
