Sediment Characteristics of Tidal Deposits at Mandvi, Gulf of Kuchchh, Gujarat, India: Geophysical, Textural and Mineralogical Attributes

Nair Department of Earth and Environmental Science Temple University 1901 N. 13th Street Philadelphia PA 19122 USA Department of Geology and Geophysics Indian Institute of Technology Kharagpur-721302 Department of Ocean Engineering Indian Institute of Technology Madras-600036 National Geophysical Research Institute Hyderabad 500606 India Structural Engineering Research Centre Chennai-600113 Variable Energy Cyclotron Centre Kolkatta 700064

The textural and mineralogical characteristics of subsurface sediments along with Ground Penetrating Radar (GPR) data collected along the Western margin of India were used to understand the depositional environments and the provenance of sediments. Textural attributes such as mean, standard deviation, skewness and Kurtosis show fluctuations due to fluvio-marine interaction and it is well understood that the bottom sediments are enriched with muddy sand, which may be deposited by mean of tidal invasion. The abundance of very coarse silt to very fine sand indicates the prevalence of low energy environment. The Linear Discriminate Function analysis indicates the fluvio marine deposition of sediments under low energy condition. GPR data upto a depth of 5 m shows the stratigraphic sequences of very fine sands and coarse silt. Optically Stimulated Luminescence (OSL) dating of sediments implies that the tidal sediments had deposited between ~30 ± 1 and ~90 ± 4 years before Present. XRD studies results the dominance of K-feldspar and deficiency of clay minerals, indicating that most of the sediments are derived from hinterland. Studies indicate that the Provenance of sediments in the Mandvi area is not related to Indus delta even though a considerable part of Gulf sediments are deposited by the Indus River.

Pelvic arterial embolization in obstetric hemorrhage

World Journal of Obstetrics and Gynecology 2013年第4期2卷 185-191页

作者： Vidhi Chaudhary Poonam Sachdeva Raksha Arora devender kumar Priya Karanth Department of Obstetrics and Gynecology Maulana Azad Medical College and associated Lok Nayak Hospital and GB Pant Hospital New Delhi 110002 India

AIM: To analyze safety and efficacy of pelvic arterial embolization(PAE) in preventing and treating obstetrical ***: A consecutive study of eight cases undergoing pelvic artery embolization from January 2010 to October 2012 in Department of Obstetric and Gynecology of Maulana Azad Medical College for intractable obstetric hemorrhage was done. All embolization were carried out in cath lab of cardiology Department at associated GB Pant ***: Clinical success was defined as arrest of bleeding after PAE without need for repeat PAE or additional surgery which was 75% in our series. PAE was successful in controlling obstetrical hemorrhage in all except one who had mortality. Other had hysterectomy due to secondary hemorrhage. Five resumed menstruation. None of the women intended to conceive, hence are practicing contraception. CONCLUSION: PAE is minimally invasive procedure which should be offered early for hemostasis in intractable obstetrical haemorrhage unresponsive to uterotonic. It is a fertility sparing option with minor complications.

Oxide ancillary ligand-based europium β-diketonate complexes and their enhanced luminosity

Rare Metals 2021年第10期40卷 2873-2881页

Ternary materials of europium complex with2,2,6,6-tetramethyl-3,5-heptanedione(tmhd) ligand and aqua ligand as ancillary ligands have been prepared and characterized for various optoelectronic *** of hydrated complex [Eu(tmhd)_(3)(H_(2)O)_(2)] proceeded with triphenylphosphine oxide(TPPO) and pyridine-N-oxide(PNO) ancillary ligands were studied to develop novel complexes. The prepared complexes show good thermal stability. A comparative investigation of preparedmaterials[Eu(tmhd)_(3)(H_(2)O)_(2)],[Eu(tmhd)_(3)(TPPO)_(2)] and [Eu(tmhd)_(3)(PNO)_(2)] was conducted for their luminescent behaviors in order to obtain the role of ancillary ligand in the enhancement of illumination amount generated from europium(Eu^(3+)) ion. Color coordinates of prepared ternary complexes such as[Eu(tmhd)_(3)(H_(2)O)_(2)]with(x = 0.54,y = 0.32),[Eu(tmhd)_(3)(TPPO)_(2)] with(x = 0.56, y = 0.32) and[Eu(tmhd)_(3)(PNO)_(2)] with(x = 0.57, y = 0.33) indicated that these materials exhibited bright red emission in visible region spectrum. The complexes show a proficient energy transport pathway from the ligands to the innermost Eu^(3+)by means of an ancillary ligand-sensitized luminescence process. Interaction between the metal and ligand results in a distinguished effect on quantum efficiency(η) as well as on Judd–Ofelt intensity factor(Ω_(2)) of the prepared materials.

＜正＞The potential for oxidative stress to contribute to benzene toxicity is closely tied to specific benzene metabolites like hydroquinone （HQ）. HQ may be oxidized to p-benzoquinone, which is highly reactive and can covalently bind to cellular macromolecules or to glutathione. Alternatively, benzene metabolites may engage in redox cycling,
