    Opis:
    At room temperature, the normal oxide spinel NiCr₂O₄ is tetragonally distorted and crystallizes in the I4₁/amd space group due to cooperative Jahn-Teller ordering driven by the orbital degeneracy of tetrahedral Ni²⁺. The ferrimagnetic Curie temperature (T_{C}) for NiCr₂O₄ is 74 K. The magnetic moments of NiCr₂O₄ are composed of a ferrimagnetic (longitudinal) and an antiferromagnetic (transverse) component. Exchange interaction between the magnetic cations influences the overall magnetic properties of the compound. Present work focuses on the modification of structural and magnetic properties upon substituting Fe at Cr site in NiCr₂O₄ with the motivation of changing the magnetic exchange interaction. In order to do so, single phase Ni(Cr_{0.5}Fe_{0.5})₂O₄ samples were prepared by co-precipitation techniques, while controlling the pH of precipitation. Upon Fe substitution, crystal structure was not affected much contrary to the earlier reports. In order to determine the oxidation state of each elements X-ray photoelectron spectroscopy (XPS) was performed. T_{C} was found to increase dramatically above 300 K, confirmed both from temperature and field dependent dc-magnetization studies.

    Opis:
    The electron transfer reaction of L-cysteine (RSH) with pyridinium chlorochromate (PCC) has been studied spectrophotometrically over the range 2.0 ≤ 10^3 [RSH] ≤ 6.0; 0.01 ≤ [H+] ≤ 0.2; 298 ≤ T ≤ 318 K and I = 0.3 mol dm-3 (NaClO4). The electron transfer reaction has also been carried out in the presence of anionic, cationic and neutral micelle. The reaction in acid medium is strongly catalyzed by changing [SDS]T (sodium dodecyl sulfate) up to 3 × 10-2 mol dm-3, beyond this concentration of SDS, the rate is retarded. The cationic and neutral micelle has a small effect on the rate. ΔH≠ (kJ mol-1) and ΔS≠ (JK-1 mol-1) values for the k1 and k2 paths are 30.20 ± 0.25, -159.65 ± 0.83 and 29.60 ± 0.62, -127.09 ± 2.17, respectively. The negative activation entropy is indicative of the ordered transition state for the electron transfer reaction. Formation of 2-amino-3-(2-amino-2-carboxy-ethyl) disulfanyl-propanoic acid as product is strongly supported by IR spectra.

    Opis:
    Background. Poor oral health among children is common finding in the rural regions of India. But if the existent structure of primary health care is used, favourable oral health habits and importance of oral health can be instilled in the children and their parents at a very early stage. Objective. To evaluate the effectiveness of Anganwadi workers (AWWs) in improving the oral hygiene of the preschool children through oral health education. Material and methods. 250 children in the age group of 2.5-6 years, were included in the study. The study was conducted in three phases over a period of 8 months which included a follow up of six months. Baseline oral health was determined using a questionnaire assessing the oral hygiene practices and DMFT Index, Plaque Index and Gingival Index. This was re-assessed after 6 months using the same questionnaire and indices. Statistical significance was fixed at p value Ł 0.05. Chi square and paired ‘t’ test were used to assess the difference in the variables after providing oral health education. Results. Out of 250 children, with mean age of 4.24 years, majority were girls (142, 56.8%). The use of fluoridated toothpaste among the study population significantly increased from 34.4% to 41.5% (p=0.001) with the intervention of oral health education (OHE). Decrease in consumption of sticky sugar, addition of sugar in the night-feeds and cleaning of teeth after night-feeds were also found to change significantly. Gingival index showed significant reduction after OHE (p=0.001). Conclusion. The study revealed that training of Anganwadi workers (AWWs) could be used to improve the oral health of the Anganwadi children. They represent an untapped source for delivering oral care to rural communities that otherwise have limited access.
