We, the Editors and Publisher of The International Journal of the History of Sport, have retracted the following article:Amitava Chatterjee (2015), The Man Arrives: Breaking Off the Notion of Effeminacy in Colonial Bengal. The International Journal of the History of Sport, 32:3, pages 409–421.The reason for retraction is significant overlap with the following previously published sources, which include the author’s own work, without appropriate acknowledgement:Amitava Chatterjee (2015), From courtyard sport to competitive sport: evolution of wrestling in colonial Bengal. Sport in Society; 18:1; pages 1–16.Boria Majumdar (2003), The Vernacular in Sport History. The International Journal of the History of Sport, 20:1; pages 107–125.We have been informed in our decision-making by our policy on publishing ethics and integrity and the Committee on Publishing Ethics (COPE) guidelines on retractions. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’. 相似文献

In this two part article I try to convey some of the variety and excitement involved in the application of mathematics to
engineering problems; to provide a taste of some actual mathematical calculations that engineers do; and finally, to make
clear the distinctions between the applied subject of engineering and its purer parents, which include mathematics and the
physical sciences. Two main points of this article are that in engineering it is approximation, and not truth, that reigns;
and that an engineer carries a burden of responsibility that mathematicians and scientists are spared. In this first part,
I present my views on how engineering differs from mathematics and the physical sciences, and describe what I consider the
workhorses of engineering calculations. 相似文献

Present study aimed to evaluate the protective role of the aqueous extract of Phyllanthus niruri (P. niruri) against nimesulide-induced
hepatic disoder in mice by determining levels of glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase
(GPT) and alkaline phosphatase (ALP) in serum and also by measuring the hepatic content of the antioxidant enzymes, superoxide
dismitase (SOD) and catalase (CAT); the free radical scavenger, reduced glutathione (GSH) and thiobarbituric acid reacting
substances (TBARS). Aqueous extract of P. niruri was administered either orally or intraperitoneally in different doses and
times as needed for the experiments. Intraperitoneal of the extract (100 mg/kg body weight for seven days) reduced nimesulide
(750 mg/kg body weight for 3 days) induced increased levels of GOT (37.0±1.8 units/ml in control group vs. 91.8±2.0 units/ml
in nimesulide treated group vs. 35.0±1.0 units/ml in extract treated group), GPT (30.0±2.1 units/ml in control group vs. 88.4±2.9
units/ml in nimesulide treated group vs. 34.1±1.8 units/ml in extract treated group), and ALP (7.86±0.47 KA units/ml in control
group vs. 23.80±0.60 KA units/ml in nimesulide treated group vs. 7.30±0.40 KA units/ml, in extract treated group) to almost
nomal. In addition, P. niruri restored the nimesulide induced alterations of hepatic SOD (550±20 units/mg total protein in
control group vs. 310±13 units/mg total protein in nimesulide treated group vs. 515±10 units/mg total protein in extract treated
group), CAT (99.5±2 units/mg total protein in control group vs. 25.0±1.5 units/mg total protein in nimesulide treated group
vs. 81.0±0.8 units/mg total protein in extract treated group), GSH (90±3 nmoles/mg total protein in control group vs. 17±4.2
nmoles/mg total protein in nimesulide treated group vs. 81±1 nmoles/mg total protein in extract treated group) and TBARS (measured
as MDA, 36.6±3.0 nmoles/g liver tissue in control group vs. 96.3±5.2 nmoles/g liver tissue in nimesulide treated group vs.
41.2±1.7 nmoles/g liver tissue in extract treated group) contents. Dose-dependent studies showed that the herb could protect
liver even if the nimesulide-induced injury is severe. Intraperitoneal administration of the extract showed better protective
effect than oral administration. Combining all, the data suggest that P. niruri possesses hepatoprotective activity against
nimesulide-induced liver toxicity and probably acts via an antioxidant defense mechanism. To the best of our knowledge, this
is the first report of the hepatoprotective action of P. niruri against nimesulide induced liver damage. 相似文献

ABSTRACT
Purpose
This paper is concerned with the impact of the University of California Cooperative Extension (UCCE) on regional productivity in California agriculture. UCCE is responsible for agricultural research and development (R&D), and dissemination of agricultural know-how in the state. 相似文献16.
This article focuses on one of the promising and emerging nanolevel imaging techniques: Atomic Force Microscopy (AFM). In
recent studies, AFM has been extensively used to understand intricate biological phenomena like prokaryotic and eukaryotic
genome organization, different DNA transaction activities, protein chaperoning and also protein-nucleic acid organization
in viruses. 相似文献

ABSTRACTFeelings of community increase information flow, cooperation, support, and a sense of commitment toward group goals. Many studies have explored the significance of sense of community and collaborative learning activities in online learning environments. Using a correlational study, the relationship between students’ sense of community and their attitude toward online collaborative learning was examined in this study. Results indicate that collaboration and sense of community were moderately correlated. A positive correlation between collaboration and students’ sense of community was determined. It was also noticed that the degree of correlation between sense of community and collaborative learning was higher among graduate students than among undergraduate students. Furthermore, a higher degree of correlation existed between a positive attitude toward collaborative learning and the dimensions of sense of community when compared to the correlation between a negative attitude toward collaborative learning and sense of community. 相似文献

Evidence of increased oxidative stress in patients of osteoarthritis in comparison with healthy control subjects was investigated
by measuring the thiobarbituric acid reactive substances (TBARS), vitamin C, reduced glutathione (GSH) and the activities
of superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx) in erythrocytes. It was observed that osteoarthritis
patients were more susceptible to oxidative damage than controls as evident from increased TBARS and decreased ascorbic acid,
GSH, catalase and GPx in erythrocytes. Significant increase in SOD activity found in patients might be an adaptive response.
With the understanding of the role of antioxidants in arthritis, it is becoming increasingly clear that these agents seem
to be beneficial in osteoarthritis. 相似文献

A method has been developed to separate and identify thyroglobulin autoantibody (TgAb) and thyroid peroxidase autoantibody
(TPOAb) in serum obtained from normal and autoimmune thyroid diseases using phenyl Sepharose CL-4B hydrophobic column. The
protein peaks obtained from hydrophobic column were identified as TgAb and TPOAb by comparing the elution profile of commercially
purified standard thyroid autoantibodies. The similarity of the inhibitory effects of eluted proteins and of standard thyroid
autoantibodies on lectin concanavalin A-RBC interaction confirmed the separation of TPO-Ab and TgAb by the hydrophobic, column.
The eluted fractions from the hydrophobic column were estimated by the radio immunoassay (RIA) to confirm the presence of
both auto-antibodies. This hydrophobic column method offers an advantage of visual inspection of this autoantibodies by graphic
representation of peak height along with their estimation in autoimmune thyroid disorders. 相似文献
