Democracy in South Africa Today : A Feminist Perspective

Kusum Datta Research Institute of Asian Women Sookmyung Women' 2005 Asian Women Vol.20 No.-

The new democratic constitution and the three general elections in South Africa since 1994 have redrawn the political map of the country. South Africa has one of the most women friendly governments led by the African National Congress. Nearly thirty three percent of the members of its Parliament are woman, and a large number of its power cabinet ministries are headed by black women. Yet, women remain the most deprived and the poorest section of its population with minimal recourse to resources and employment despite many legal reforms and gendered policies. This paper argues that South Africa's elaborate national machinery for gender equity has failed to improve women's situation primarily for two reasons. The first is the weakening political will of the government partly because of the growing influence of international financial institutions that prioritize fiscal balance at the expense of social justice. Secondly, there is a growing disjuncture between the feminists within the government and the bureaucracy on the one hand and the fractured women's movement in civil society on the other. The paper underscores the imperative need for strengthening the new type of civil society organisations and their pressure group capacity to support women within the government and to hold them accountable to the feminist project.

Datta, R.K.,Basavaraja, H.K.,Reddy, N.Mal,Kumar, S.Nirmal,Kumar, N.Suresh,Babu, M.Ramesh,Ahsan, M.M.,Jayaswal, K.P. Korean Society of Sericultural Science 2001 International Journal of Industrial Entomology Vol.3 No.2

With an objective of evolving quantitatively and qualitatively superior bivoltine breeds/hybrids of silkworm Bombyx mori L. for tropical conditions, breeding work was initiated in Central Sericultural Research and Training Institute, Mysore during 1992 by utilizing two Japanese hybrids namely BNl8$\times$BCS25 and Shunrei$\times$Shogetsu along with Indian evolved breed, KA. The breed CSR12 which is characterized with sex-limited larval marking and white oval cocoons was evolved from the Japanese hybrid BNl8 ${\times}$ BCS25 by crossing with KA, while the breed CSR6 which is characterized with normal marking (marked larvae) and white dumbbell cocoons was extracted from the Japanese commercial hybrid Shunrei${\times}$Shogetsu through continuous inbreeding coupled with selection. After fixation, these breeds along with other newly evolved breeds were subjected to hybrid study under optimum environmental conditions in the laboratory for expression of full potential of the genotypes. These hybrids were evaluated by Multiple Trait Evaluation Index (Mano et al., 1993). The hybrid CSR12${\times}$CSR6 was selected based multiple trait evaluation index value. The hybrid CSR12$\times$CSR6 recorded survival of 96.0%, shell weight of 50.0 cg, shell ratio of 24.3%, raw silk percentage of 19.6, filament length of 1,216 m, boil off loss of 22.4% and renditta of 5.1. On the other hand, the control hybrid (KA ${\times}$ NB4D2) has recorded survival of 90.6%, shell weight of 42.1 cg, shell ratio of 20.4%, raw silk percentage of 15.9, filament length of 999 m, boil off loss of 24.8% and renditta of 6.3. The hybrid CSR12$\times$CSR6 was authorized during 1997 by Central Silk Board, Government of India for commercial exploitation during favourable months based on national level race authorization test.

<P><B>Grabbing CO<SUB>2</SUB> from wet gas streams</B></P><P>It is a challenge to extract CO<SUB>2</SUB> from typical gas streams, such as the flue gas from a power plant. This is because any water in the stream tends to prevent CO<SUB>2</SUB> absorption and may also degrade the absorbing material. Datte <I>et al.</I> developed a microporous copper silicate that avoids these problems. Most other materials have sites that absorb both water and CO<SUB>2</SUB> at the same sites, and in that fight, the water tends to win. Although their material still absorbs water, it has separate sites for the CO<SUB>2</SUB> absorption.

Therefore, it readily adsorbs both H<SUB>2</SUB>O and CO<SUB>2</SUB> from the humid flue gases and atmosphere, but the adsorbing H<SUB>2</SUB>O does not interfere with the adsorption of CO<SUB>2</SUB>.

Recent Breakthroughs in Sericultural Technology in India to Match the Requirement of Silk Industry in Tropics

Datta, R.K. Korean Society of Sericultural Science 2000 International Journal of Industrial Entomology Vol.1 No.2

Strengthening of R & D components of sericulture in India since the sixties has led to a quantum jump in silk production and presently India is the second largest producer in the world. This achievement is primarily due to a number of breakthroughs in R & D to match the requirements of tropics, by way of introduction of improved mulberry varieties and silkworm breeds, better mulberry cultivation and rearing management practices suited to tropical conditions. Of late, new approaches in molecular biology and biotechnology have also been vigorously pursued to strengthen the current conventional strategies. The present paper attempts to provide an overview of the present status of silk production in both mulberry and non-mulberry sectors, breakthroughs achieved through new approaches of biotechnology and the future prospects for maximizing silk productivity in India.

Synthesis of large monodisperse ETS-10 crystals and observation of quantum confinement effects from very long titanate quantum wires

Datta, S.J.,Yoon, K.B. Elsevier Science Publishers 2013 CATALYSIS TODAY - Vol.204 No.-

Synthetic conditions to produce highly crystalline monodisperse ETS-10 crystals with the length along the [110] direction (L<SUB>[110]</SUB>) between 17 and 55μm and the length along the [001] direction between 15 and 80μm were developed. This was achieved by varying the amounts of KF in the gel consisting of Na<SUB>2</SUB>SiO<SUB>3</SUB>, titanium isopropoxide, HCl, NaCl, KF, and H<SUB>2</SUB>O. The UV-vis spectra of the ETS-10 crystals revealed that the absorption band red-shifts with increasing L<SUB>[110]</SUB>. The plot of band gap energies (E<SUB>g</SUB> values) with respect to L<SUB>[110]</SUB> values revealed a progressively decaying relationship. The mixing of the newly observed data set with that reported previously from the ETS-10 crystals with L<SUB>[110]</SUB> between 0.3 and 20μm gave a smooth exponential decay relationship, E<SUB>g</SUB>=0.2578 exp(-L<SUB>[110]</SUB>/13.751)+3.7667, as if they came from a single data set. Analysis shows that the quantum confinement effect still operates in TiO<SUB>3</SUB><SUP>2-</SUP> quantum wires with the estimated length of 368nm. The μ<SUB>xy</SUB> and μ<SUB>z</SUB> values are 15.2 and 0.0006m<SUB>e</SUB>, respectively. A monotonous quadratic relationship exists between L<SUB>[110]</SUB> and l. Thus the length of the titanate quantum wire increases more than the degree the crystal size increases, indicating that the degree of defect per unit volume decreases as the crystal size increases.

Potential Benefit of Genetic Engineering in Plant Breeding: Rice, a Case Study

Datta, Swapan K. The Korean Society for Applied Biological Chemistr 2000 Journal of Applied Biological Chemistry (J. Appl. Vol.43 No.4

This paper summarizes recent developments in the field of molecular biology and its application to plant breeding, particularly in rice. Plant breeding in the past mostly depended on the time-consuming crossing of known genomes limited to certain traits. Plant breeding has now benefited from marker-assisted selection and genetic engineering to widen the gene pool, improve plant protection, and increase yield. Future plant breeding will expand based on functional and nutritional genomics, in which gene discovery and high-throughput transformation will accelerate crop design and benefits will accrue to human health, in the form of nutritional food for poor people to reduce malnutrition, or food enriched with antioxidants and with high food value for rich people. Agricultural biotechnology for food is no longer a dream but a reality that will dominate the 21st century for agriculture and human welfare.

The Bacteriophage λ DNA Replication Protein P Inhibits the oriC DNA- and ATP-binding Functions of the DNA Replication Initiator Protein DnaA of Escherichia coli

Datta, Indrani,Sau, Subrata,Sil, Alok Kumar,Mandal, Mitai C. Korean Society for Biochemistry and Molecular Biol 2005 Journal of biochemistry and molecular biology Vol.38 No.1

Under the condition of expression of $\lambda$ P protein at lethal level, the oriC DNA-binding activity is significantly affected in wild-type E. coli but not in the rpl mutant. In purified system, the $\lambda$ P protein inhibits the binding of both oriC DNA and ATP to the wild-type DnaA protein but not to the rpl DnaA protein. We conclude that the $\lambda$ P protein inhibits the binding of oriC DNA and ATP to the wild-type DnaA protein, which causes the inhibition of host DNA synthesis initiation that ultimately leads to bacterial death. A possible beneficial effect of this interaction of $\lambda$ P protein with E. coli DNA initiator protein DnaA for phage DNA replication has been proposed.

Research Advances on Tension Buckling Behaviour of Aerospace Structures: A Review

Datta, Prosun Kumar,Biswas, Sauvik The Korean Society for Aeronautical and Space Scie 2011 International Journal of Aeronautical and Space Sc Vol.12 No.1

This paper reviews most of the research done in the field of tensile buckling characteristics pertaining to aerospace structural elements with special attention to local buckling and parametric excitation due to periodic loading on plate and shell elements. The concepts of buckling in aerospace structures appear as the result of the application of a global compressive applied load or shear load. A less usual situation is the case, in which a global tensile stress creates buckling instability and the formation of complex spatial buckling pattern. In contrast to the case of a pure compression or shear load, here the applied macroscopic load has no compressive component and is thus globally stabilizing. The instability stems from a local compressive stress induced by the presence of a defect, such as a crack or a hole, due to partial or non-uniform applied load at the far end. This is referred to as tensile buckling. This paper discusses all aspects of tensile buckling, theoretical and experimental. Its far reaching applications causing local instability in aerospace structural components are discussed. The important effects on dynamic stability behaviour under locally induced periodic compression have been identified and influences of various parameters are discussed. Experimental results on simple and combination resonance characteristics on plate structures due to tensile buckling effects are elaborated.
