The Intelligibility of English in Global Contexts: Concepts, Methods, Findings and Implications
Jagdish Kaur 서울대학교 외국어교육연구소 2018 외국어교육연구 Vol.22 No.-
Intelligibility is considered key to successful and effective human communication. The intelligibility of the English used by its non-native speakers is the subject of much research enquiry, and as English continues to strengthen its foothold in international settings as the global lingua franca, the issue of mutual intelligibility has never been of greater importance. The paper begins by examining “intelligibility” as conceptualized by scholars in the fields of World Englishes (WE) and English as a lingua franca (ELF). While WE scholars approach the subject by investigating the international intelligibility of the new varieties of English, particularly to other non-native speakers of the language, ELF researchers seek to uncover how speakers negotiate and co-construct intelligibility in interaction, and the kinds of accommodation strategies employed in the process. Although the underlying assumptions and the methodologies associated with the 2 fields are not always congruent, the findings contribute towards developing a clearer picture of the subject of intelligibility in global communication. The paper ends by considering the pedagogical implications of the findings of intelligibility studies in WE and ELF.
Experimental Investigation of Block Shear Failure in a Single Angle Tension Member
Jagdish R. Dhanuskar,Laxmikant M. Gupta 한국강구조학회 2020 International Journal of Steel Structures Vol.20 No.5
A limited test data are available for double-bolt line connection in a single angle tension member, which failed in block shear. To address this, twelve single angle tension members with a double bolt-line connection was reported in this paper, considering the block aspect ratio and connection length as the test parameters. All the tested specimens were failed in block shear. For the tested specimens, numerical analysis was performed, which shows good agreement with experimental results. Experimental outcomes were then compared with the current design provisions present in the IS 800, AISC, CSA, AIJ, EC 3, SBC, and with other existing proposed models. These standards and models show some discrepancies with regard to the experimental results. This discrepancy was due to the shear failure plane position as assumed in the design standards. Those shear planes were specifi ed in the standards as net and gross shear planes. However, the experimental and numerical investigation shows that between the gross shear plane and the net shear plane lies the actual shear failure plane. Based on this, the block shear mechanism was modifi ed and proposed a rational equation that provides a more exact prediction of block shear capacity than the current design standards and the other existing models. The proposed block shear equation shows the precise forecast for both single and double-bolt line connections used in a single angle tension member.

Horizontal Pullout Resistance of a Group of Two Vertical Anchors in Sand
Jagdish Prasad Sahoo,Jyant Kumar 대한토목학회 2013 KSCE Journal of Civil Engineering Vol.17 No.7
The horizontal pullout capacity of a group of two vertical strip anchors placed along the same vertical plane in sand has been determined by using the upper bound finite elements limit analysis. The variation of the efficiency factor (ξγ) with changes in clear spacing (S) between the anchors has been established to evaluate the total group failure load for different values of (i) embedment ratio (H/B), (ii) soil internal friction angle (φ), and (iii) anchor-soil interface friction angle (δ). The total group failure load, for a given H/B, becomes always maximum corresponding to a certain optimal spacing (Sopt). The value of Sopt/B was found to lie in a range of 0.5-1.4. The maximum magnitude of ξγ increases generally with increases in H/B, φ and δ.
Shear Lag Effect in Welded Single Angle Tension Member
Jagdish R. Dhanuskar,Laxmikant M. Gupta 한국강구조학회 2021 International Journal of Steel Structures Vol.21 No.3
The typical failure of a welded single angle tension member is a gross section failure. The rupture strength of the single angle tension member is aff ected by the eff ect of shear lag. Full-scale tests on twenty-seven single angle specimens reported in this paper. Four diff erent angle sections with four diff erent section types were used in the test. The test parameter includes the steel’s grade, length of the connection, the eccentricity of the connection, and balanced and unbalanced weld arrangement. Twenty-three specimens failed by fracture of the gross section area, one failed in mixed mode (angle tear and the weld failure), and the remaining three failed in the weld. To interpret the experimental results, fi nite element analysis was performed on the specimen’s model. The fi nite element model well represents the welded single-angle tension member’s behaviour, and fi nite element results show exemplary test results. The ultimate strengths of the test specimens were also evaluated by using the current design standards (IS 800, AISC, CSA, AS 4100, and EC-3), the (1− x̅/L) rule, and Kulak and Wu’s equation. In general, IS 800 provides a good prediction of test results, AISC and AS 4100 provide a slightly conservative forecast; however, CSA and EC-3 provide a slightly un-conservative prediction. For a balanced weld arrangement, the specimen’s ultimate strength increased with an increase in connection length; however, an increase in connection length does not increase the specimen’s ultimate strength for an unbalanced weld arrangement. The angle specimen’s effi ciency decreased signifi cantly with an increase in eccentricity. The rupture strength predicted by assuming the ultimate strength of the connected leg and the strength contributed by the outstanding leg at the critical section shows a good prediction of the strength over the (1− x̅/L) rule.

Background: Ashwagandharishtha is a liquid polyherbal formulation traditionally prepared by fermentation process using the flowers of Woodfordia fruticosa. It contains roots of Withania somnifera as a major crude drug. Alcohol generated during the fermentation causes the extraction of water insoluble phytoconstituents. Yeasts present on the flowers are responsible for this fermentation. Methods: Total nine formulations of ashwagandharishtha were prepared by fermentation process using traditional Woodfordia fruticosa flowers (ASG-WFS) and using yeasts isolated from the same flowers. During fermentation, kinetic of alcohol generation, sugar consumption, changes in pH and withanolides extraction were studied. All the formulations were tested for in vitro antioxidant potential by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) free radical scavenging, hydrogen peroxide scavenging and total reducing power assay. The results were compared with standard ascorbic acid. Results: Traditional formulation (ASG-WFS) showed the highest activity (p < 0.001) relative to other formulations and standard ascorbic acid. ASG-WFS showed significant (DPPH) free radical scavenging (78.75%) and hydrogen peroxide scavenging (69.62%) at the concentration of 1000 μg/mL and 100 μg/mL, respectively. Conclusion: Traditional process is the best process for preparing ashwagandharishtha to obtain significant antioxidant activity.
