Camouflage of Fragmentation and Alienation in Nathanael West's A Cool Million
No full textThis paper examines West's satire and parody of the various schools of philosophic and artistic concepts that precede and underpin the Modem movement. By revealing the absurdity of Western thought in the early twentieth century, West was able to show the fragmentation and alienate he perceived in both society and the self. The revelation of this detritus becomes a deconstructive device that simultaneously demonstrates ways of creating meaning in the twentieth century, and that condemns any philosophy based on escape from suffering. The novel A Cool Million, variously attack artistic or political formulae that privilege escape from culture's degradation, or that offer erroneous promises of subjective or cultural wholeness. West's life and art, then, exhibits the usefulness of the camouflage in the grim battle for the formation of artistic and political subjectivity. Nathanael West's novel stands as significant reminders of the worry that plagued America and the reality almost a century back. There may be undoubtedly a greater amount that can, and should, a chance to be said around West as much worth of effort. Routes for considering regarding culture, politics, history, art, and the puzzling state of constantly human need aid all miserably joined Previously, as much dream. Such worries talk potently and straightforwardly to those birthplaces of the exhibit. Fragmentation and alienation are themes that carry over into West's novel, A Cool Million. West's novel, A Cool Million, would attack, exposing the grinding greed underlying the capitalist cliches of the American Dream. Because of this satire, the novel is important not only in what it exposes but also because it marks the turn in West's work to a much more specifically American literature. Fragmentation and alienation are of the modern world having deeply affected not only the realms of politics and rhetoric, but also the everyday landscape of common objects. There would be nothing but the blank suffering of alienated and fragmented beings in a shattered world. P. Ranjithkumar | Dr. R.

Preference shifts in Bemisia tabaci (Aleyrodidae: Hemiptera) after the acquisition of Mungbean Yellow Mosaic Virus from Vigna radiata
No full textThe silver leaf whitefly, Bemisia tabaci (Aleyrodidae: Hemiptera), is a polyphagous pest and a major vector of plant viruses, causing significant economic losses globally. It exhibits a complex of cryptic species and is known to transmit various plant viruses affecting numerous crops globally. A study was conducted in Tamil Nadu, India, to identify the dominant cryptic species of B. tabaci on legume crops, leading to the establishment of laboratory colonies of the most common types. The research focused on the feeding preferences of these whiteflies on healthy green gram plants (Vigna radiata (L.) R. Wilczek) versus those infected with the Mungbean Yellow Mosaic Virus (MYMV). Biochemical changes in MYMV-infected green gram plants, compared to healthy ones, were analysed to understand their influence on whitefly feeding preference. The cryptic species Asia II 8 was found to be the most common in legume crops. The study assessed whether these whiteflies favoured healthy green gram plants or those infected with MYMV. Our findings revealed that when healthy whiteflies acquired the virus from the host, their preference shifted toward healthy plants. This shift is linked to the biochemical changes associated with the infection status of the host. Following viral infection, there was a decrease in total sugars and chlorophyll, while levels of protein, phenol, peroxidase, and polyphenol peroxidase increased. These results suggest that the virus modifies the vectors’ behaviour through a shared host, enhancing the pathogens’ ability to disseminate within the ecosystem
Development of a 100 mm-Diameter Split-Hopkinson Pressure Bar for High Strain Rate Characterization of Concrete
No full textThe Split-Hopkinson Pressure Bar (SHPB) is an experimental technique used to examine the behavior of materials at high strain rates. The aim of this paper is to present the development of a SHPB for the testing of concrete at high strain rates. The construction of the SHPB is detailed, including the important decisions made during its development. The basic calibration of the setup has been performed. The ordinary and fiber reinforced concrete (FRC) specimens (M30) with a diameter of 100 mm and L/D ratio of 0.5 are tested at a strain rate of about 50 to 65 s−1. The comparison of the results from the SHPB test and the quasi-static test is also presented. From the results, it is concluded that the developed SHPB is giving consistent results for the ordinary concrete, whereas for FRC specimens, there is a difference in the peak stress, which could be the variabilities in the dispersion of fibers in the concrete. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd

Crystal structures of 6a,6b,7,11a-tetrahydro-6H,9H-spiro[chromeno[3′,4′:3,4]pyrrolo[1,2-c]thiazole-11,3′-indoline]-2′,6-dione and 5′-methyl-6a,6b,7,11a-tetrahydro-6H,9H-spiro[chromeno[3′,4′:3,4]pyrrolo[1,2-c]thiazole-11,3′-indoline]-2′,6-dione
No full textThe title compounds, C20H16N2O3S, (I), and C21H18N2O3S, (II), differ by the presence of a methyl group in position 5 on the 1H-indole-2-one ring of compound (II). The two compounds have a structural overlap r.m.s. deviation of 0.48 Å. There is a significant difference in the conformation of the thiazolidine ring: it has a twisted conformation on the fused N—C bond in (I), but an envelope conformation in compound (II) with the S atom as the flap. The planar pyrrolidine ring of the indole ring system is normal to the mean plane of the five-membered pyrrolidine ring of the pyrrolothiazole unit in both compounds, with dihedral angles of 88.71 (9) and 84.59 (8)°. The pyran rings in both structures have envelope conformations with the methylene C atom adjacent to the C=O group as the flap. In both compounds, there is a short intramolecular C—H...O contact present. In the crystal of (I), molecules are linked by C—H...O hydrogen bonds forming chains propagating along the b-axis direction. The chains are linked by N—H...π interactions, forming layers parallel to (10\overline{1}). In the crystal of (II), molecules are linked by pairs of N—H...O hydrogen bonds, forming inversion dimers which are linked by C—H...O hydrogen bonds to form a three-dimensional structure

Structure and Reactivity of Halogenated GC PNA Base Pairs – A DFT Approach
No full textThe present study explored the structural and reactivity relationship of halogenated G-C PNA base pairs using density functional theory (DFT) calculations. The halogens such as F, Cl, and Br are substituted by replacing H atoms involved in H-bonds of the base pairs. All structures were optimized using the B3LYP/6-311++G** theory level, and positive frequencies confirmed their equilibrium states. To understand the structural variations of the considered halogenated systems, the bond distances of R─X, R─H, and X/H•••Y and the bond angles of R─X•••Y were analyzed. The obtained structural parameters and interaction energies are comparable with the previous theoretical reports. In addition, the interaction energies (Eint) and quantum molecular descriptors (QMD) are also calculated to understand the difference between halogenated PNA systems and their non-halogenated counterparts. In this study, the enhancement in the reactivity properties of halogenated PNA systems has been demonstrated, which indicates their improved responsive characteristics in various chemical reactions. Based on the available results, the halogenated PNA systems, carefully considering their substitutional position, facilitate better accommodation for the triplex formation of dsDNA/dsRNA. Therefore, it is concluded that the improved reactivity properties of halogenated PNA base pairs would make them potential candidates for various biological applications
