Extraction and separation of U(VI) and Th(IV) from hydrobromic acid media using Cyanex-923 extractant
Ghag Snehal M.,Pawar Suresh D.
Journal of the Serbian Chemical Society , 2010, DOI: 10.2298/jsc090617118g
Abstract: A systematic study of the solvent extraction of uranium(VI) and thorium(IV) from hydrobromic acid media was performed using the neutral phosphine oxide extractant Cyanex-923 in toluene. These metal ions were found to be quantitatively extracted with Cyanex-923 in toluene in the acidity range 5x10-5-1x10-4 M and 5x10-5-5x10-3 M, respectively, and they are stripped from the organic phase with 7.0 M HClO4 and 2.0- 4.0 M HCl, respectively. The effect of the equilibrium period, diluents, diverse ions and stripping agent on the extraction of U(VI) and Th(IV) was studied. The stoichiometry of the extracted species of these metal ions was determined based on the slope analysis method. The extraction reactions proceed by solvation and their probable extracted species found in the organic phase were UO2Br2 2Cyanex-923 and ThBr4 2Cyanex-923. Based on these results, a sequential procedure for their separation from each other was developed.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.106039
Abstract: Non-linear optical materials find wide range of applications in the fields of opto-electronics, fiber optic communication, computer memory devices etc. Tris-Glycine Zinc Chloride (TGZC) is one of the NLO materials exhibiting more efficiency. In the present study Tris-Glycine Zinc Chloride were grown is single crystal form using slow evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to orthorhombic system with the space group Pbn21. The optical absorption studies show that the crystal is transparent in the entire visible region with a cut off wavelength of 250 nm. The optical band gap is found to be 4.60 eV. The dependence of extinction coefficient (K) and refractive index (n) on the wavelength has also been reported. Force constants (k) were calculated using FTIR spectral analysis which shows higher values of k for COO and C=O stretching vibrations. The dielectric studies show that the dielectric constant and dielectric loss decrease exponentially with frequency at different temperatures (35℃, 55℃, 75℃ and 95℃).

Abstract: Single crystals of Glycine Zinc Chloride (GZC) were grown from aqueous solution by slow evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to orthorhombic system with the space group Pna21.The optical transmission study reveals the transparency of the crystal in the entire visible region and the cut off wavelength has been found to be 230 nm. The optical band gap is found to be 3.40eV. The transmittance of GZC crystal has been used to calculate the refractive index (n), the extinction coefficient (K) and the real er and imaginary ei components of the dielectric constant. Mechanical studies were carried out on the as grown crystal. Dielectric constant and dielectric loss measurements were carried out at different temperatures and frequencies. Photoconductivity measurements carried out on the grown crystal reveal the negative photoconducting nature.

Abstract: Acharya Javadekar maintained that the Bhagwad Geeta laid down a code of conduct for the guidance of the kings to the followed in the wars. Lord Krishna and Arjun both were Kshatriyas (warrior Castes) and they had Kshatriya ideals to follow. The Geeta told us about the concept of the ideal warrior kng and Kshatriya's place and function in the society. Taking Arjun's Kshatriya characteristics and his duties as a warrior prince into account the Geeta espoused its teaching Mamnusara Yuddhschha. Mahatma Gandhi interpreted this axiom of the Geeta to mean “fight non-violently for truth” – and Mahatma Gandhi maintained that this interpretation was in keeping with the teaching of th Geeta. For, though all the wars were ended, the message of the Geeta was that “The war for the truth would always continue and always guide the warriors of 1truth”. Mahatma Gandhi thought this to be the chief message of the Geeta.

Abstract: It was the opinion of the Socialist Party that India had found a non-violent way of fighting against Britain (the U.K.) and American imperialism and capitalism. The Socialist Party had decided to take the people on this line. The Socialist Party was led by Jayprakash Narayan and other farsighted revolutionary leaders. India had found a new way of fighting an unarmed revolution which was going on for last 30 years under the leadership of Mahatma Gandhi. The socialists and Jayprakash Narayan thought that the socialists should continue to tread the path of Mahatma Gandhi. The socialist revolution would take place if they followed democratic way. The people of our country would not have to suffer the dictatorship like Russia.1

Abstract: The present work in relation to occurrence of Deuteromycotinous fungal flora over the groundnut fields (Arachis hypogaea L.) was carried out in winter and summer seasons of the years 2009-10 and 2010-11 using continuous Volumetric Tilak air sampler. Results revealed that the spores of Aspergillus and Cercospora occurred predominantly. Aspergillus spores contributed 8.24% and 4.31% in I and II winter seasons and 3.67% and 4.08% during I and II summer seasons respectively. Cercospora spores contributed 7.85% and 7.02% in I and II winter seasons and 2.85% and 3.97% during I and II summer seasons respectively. Curvularia spores contributed 0.62% and 1.22% during I and II winter seasons and 0.32% and 0.98% during I and II summer seasons respectively. Cladosporium spores contributed 1.54% and 1.56% in I and II winter seasons and 1.35% and 1.73% in I and II summer seasons respectively.

Abstract: Acharya Jawadekar examined Mahatma Gandhi's philosophy in the light of the vedant philosophy and analysed his concept of Analsakti Yoga (selfless pursuit of life activity). The Acharya thought that the Geeta thought the principle of non-violent Satyagraha and therefore, non violent Satyagraha was a major contribution of Mahatma Gandhi that enriched world thought.

Socialist Movements in India – A Critical Study
Review of Research , 2012,
Abstract: Acharya Jawadekar held that although Indian socialism had imbibed principles of western socialism, this imbibing was not done blindly. India had produced the India made socialism which the Indian culture had evolved through Indian freedom struggle. Hence, it was important to see how the socialists and Congress had come into contact with Indian freedom struggle.

Abstract: BACKGROUND AND OBJECTIVES: Mycobacterial infections are known to induce the development of autoantibodies and a few of these antibodies are also known to be diagnostic markers for some other diseases and it is uncertain whether these autoantibodies play a role in the pathogenesis of autoimmune disorders. This study was undertaken to determine the prevalence of autoantibodies like anti-neutrophil cytoplasmic antibodies (ANCA), anti-nuclear antibodies (ANA), anti-double stranded antibodies (anti-dsDNA) and anti-histone antibodies (AHA)in pulmonary Tuberculosis. MATERIALS & METHODS: Seventy consecutive pulmonary TB patients, 30 patients of interstitial lung disease and 100 normal individuals were studied. ANCA and ANA were detected by indirect immunofluorescence test (IIF). Anti-dsDNA and AHA were tested by ELISA. RESULTS: ANCA was detected in 30% cases, and of these 52.4% showed perinuclear pattern (p-ANCA), 38.1% cytoplasmic (c-ANCA) and 9.5% showed an ′atypical′ pattern. ANCA specificities by ELISA revealed that, 47.6% had anti-Myeloperoxidase (anti-MPO), 28.6% had anti-Proteinase3 (anti-PR3) and 19.1% had anti-Lactoferrin (anti-LF) antibodies. ANA and AHA were present in 24.3% and 21.4% cases respectively whereas anti-ds DNA antibodies were absent. Normal controls showed 4% and 2% positivity for ANA and ANCA whereas disease control group of ILD showed 7% of ANA and ANCA posititivy. CONCLUSION: The presence of autoantibodies in TB patients could have a multifactorial etiology. Clinically relevant is the presence of anti-PR3 antibodies. This finding along with pulmonary and renal manifestations could lead to a false diagnosis of Wegener′s granulomatosis or vice versa because these autoantibodies may be present in both diseases.
