Introduction. According to their textural and geochemical similarity it was suggested previously that the lunar meteorite NWA 4734 could be launch paired with Antarctic Mare basalts (LAP 02205/224/226/436-03632-04841) themselves possibly paired with NWA 032/470 lunar meteorites despite their different textures (1-5). A possible clue about the pairing issue is evidently their age. Method : After...

The cancer prevalence in the Malwa region of Punjab (1089/million/year) is much higher than the national average cancer prevalence in India (800/million/year). The participants in the present study were 50 healthy individuals and 49 cancer patients all living in the Malwa region of Punjab, with the healthy people being selected from the same household as the cancer patients. High concentrations...

Radionuclides existing in the environment, both natural and artificial, are accumulated in plants and animals and transferred through the trophic chain. That is the way which more and more wakes up to the interest of longterm impact on living organisms and the possibility of their transfer through feed way to human body. Basing on their high radiotoxicity to living organisms the alpha emitting ...

Let Δ = ABC be a reference triangle and Δ′ = A′B′C′ an inscribed triangle of Δ. We define the cevian projection of Δ′ as the cevian triangle ΔP of a certain point P . Given a point P not on a sideline, all inscribed triangles with common cevian projection ΔP form a family DP = {Δ(t) = AtBtCt, t ∈ R}. The parallels of the lines AAt, BBt, CCt through any point of a certain circumconic CP intersec...

We study the triangle bounded by the antiparallels to the sidelines of a given triangle ABC through the intercepts of the trilinear polar of a point P other than the centroid G. We show that this triangle is perspective with the reference triangle, and also study the condition of concurrency of the antiparallels. Finally, we also study the configuration of induced GP -lines and obtain an intere...

A single megacryst of Neoproterozoic monazite (“TS-Mnz”) was investigated by electron probe microanalysis (EPMA), Raman microspectroscopy, U-Pb dating isotope dilution-thermal ionization mass spectrometry (ID-TIMS), and U-Th-Pb trace element analysis laser ablation inductively coupled plasma (LA-ICPMS). The contains both distinct unaltered domains that are either homogeneous or zoned, altered w...
