Investigating topics and style in Vuta N`Kuvute by Shafi Adam Shafi
Get PDFIn the last decades many literary critics have appraised the works of Zanzibarian writers; referring to the prose of Mohamed Suleiman Mohamed, Said Ahmed Mohamed and Shafi Adam Shafi, M M. Mulokozi wrote in 1985: \"The most significant, and certainly most spectacular, development in the Swahili fiction of the Seventies and Eighties has been the emergence of Zanzibar as the producer of the best Swahili fiction to date, and the apparent torch bearer for the Kiswahili novel of the near future\" (Arnold 1985: 174). The same enthusiasm was shared by R. Ohly who, confronting the novels written by Zanzibarian writers and those by Tanzanian and Kenyan writers in a time span going from 1975 to 1981, has defined the Zanzibarian prose a challenge to the artistic competence of other Swahili writers (cf. Ohly 1990).
Although I found the comparative pattern used by Ohly debatable, having concentrated for the up-country literary production only on popular short novels - to be better evaluated not following negative, contrastive cliches but within the context of that particular trend -, obscuring moreover other talented writers like Euphrase Kezilahabi or Claude Mung`ong`o, his criticism has nevertheless the merit of having highlighted the main qualities of Zanzibarian novels, namely a deep interest for historical and social matters, along with an extremely rich and colourful language and a serious concern for stylistic features. These attributes of Zanzibarian literary style fit very well to the last novel by Shafi Adam Shafi, Vuta n`kuvute, published in 1999; in the following pages my aim is to explore the way the author of this work artistically manipulates themes, literary suggestions and stylistic devices, re-elaborating thus the experience of Kiswahili and Zanzibarian prose in a creative way

A comparative study of the CAPM and extended models in the Indian stock market
No full textTo explain the cross section of asset returns, there are numerous asset pricing models being used which require ideal conditions in the markets around the world. An attempt has been made in the present study to estimate and compare the different versions of capital asset princing model (CAPM) using the data of sectoral indices listed in S&P BSE in the Indian stock market. The two widely used approaches i.e. Fama-MacBeth (1973) and Pettengil et al. (1995) for conditional versions have been adopted in the study. The models were compared on the basis of Akaike Information Criterion (AIC) and it was obtained that the AIC value of the Unconditional higher moment CAPM was obtained minimum among other models. Hence it can be said as the better model than other models estimated
Identification of Plasmodium falciparum var1CSA and var2CSA domains that bind IgM natural antibodies
No full textMalaria in pregnancy is responsible for maternal anaemia, low-birth-weight babies and infant deaths. Plasmodium falciparum infected erythrocytes are thought to cause placental pathology by adhering to host receptors such as chondroitin sulphate A (CSA). CSA binding infected erythrocytes also bind IgM natural antibodies from normal human serum, a process that may facilitate placental adhesion or promote immune evasion. The parasite ligands that mediate placental adhesion are thought to be members of the variant erythrocyte surface antigen family P. falciparum erythrocyte membrane protein 1 (PfEMP1), encoded by the var genes. Two var gene sub-families, var1CSA and var2CSA, have been identified as parasite CSA binding ligands and are leading candidates for a vaccine to prevent pregnancy-associated malaria. We investigated whether these two var gene subfamilies implicated in CSA binding are also the molecules responsible for IgM natural antibody binding. By heterologous expression of domains in COS-7 cells, we found that both var1CSA and var2CSA PfEMP1 variants bound IgM, and in both cases the binding region was a DBL epsilon domain occurring proximal to the membrane. None of the domains from a control non-IgM-binding parasite (R29) bound IgM when expressed in COS-7 cells. These results show that PfEMP1 is a parasite ligand for non-immune IgM and are the first demonstration of a specific adhesive function for PfEMP1 epsilon type domains
An efficient one-pot multicomponent synthesis of 3,4-dihydropyrimidine-2-(1H)-ones/thiones/imines via a Lewis base catalyzed Biginelli-type reaction under solvent-free conditions
No full textAbstract3,4-Dihydropyrimidin-2(1H)-one, 3,4-dihydropyrimidin-2(1H)-thione, and 3,4-dihydropyrimidin-2(1H)-imine derivatives were synthesized by modified Biginelli cyclocondensation reaction catalyzed by triphenylphosphine as Lewis base. The structures of the synthesized compounds have been elucidated by IR, 1H NMR and elemental analysis
Correlation analysis of reactivity in the oxidation of methionine by benzimidazolium fluorochromate in different mole fractions of acetic acid–water mixture
No full textAbstractThe kinetics of oxidation of methionine (Met) by benzimidazolium fluorochromate (BIFC) has been studied in the presence of chloroacetic acid. The reaction is first order with respect to methionine, BIFC and acid. The reaction rate has been determined at different temperatures and activation parameters calculated. With an increase in the mole fraction of acetic acid in its aqueous mixture, the rate increases. The solvent effect has been analyzed using the Kamlet’s multi parametric equation. A correlation of data with the Kamlet–Taft solvatochromic parameters (α, β, π∗) suggests that the specific solute–solvent interactions play a major role in governing the reactivity. The reaction does not induce polymerization of acrylonitrile. A suitable mechanism has been proposed
