in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
Policosanol is a drug substance consisting of a mixture of very long chain alcohols (C24-C34) extracted and purified from sugar cane wax. A Gas Chromatographic method using a wide-bore capillary column, and 1-eicosanol as internal standard was developed and validated for determining policosanol in 5 and 10 mg film-coated tablets. The alcohols were analyzed as trimethylsilyl derivatives. The met...
In the I = 0 sector there are more scalar mesons than can fit in one qq nonet. Consequently, many have claimed that there is in fact more than one multiplet, perhaps both qq and qqqq. Such proposals require the existence of at least two strange isodoublets (and their antiparticles). The current PDG Tables list just one state, the K∗ 0 (1430), while fits to data with Breit-Wigner forms and varia...
OBJECTIVES We sought to assess the occurrence and clinical significance of stroke and peripheral arterial embolizations at non-central nervous system sites in a large, community-based cohort with hypertrophic cardiomyopathy (HCM). BACKGROUND Such vascular events are insufficiently appreciated complications of HCM for which there is limited information on occurrence, clinical profile and deter...
