Massive stellar content of stellar complexes and associations in M 33 is studied combining deep UBV photometry from the Local Group Survey (Massey et al. 2006) and JHK photometry from the 2MASS. Two b...
The standard model of particle physics contains N_gen=3 generations of quarks and leptons, i.e., two sets of three particles in each sector, with the two sets differing by 1 unit of charge in each. A...

Using existing experimental information from K, B and D decays as well as electroweak precision tests and oblique parameters, we provide constraints and correlations on the pa- rameters of the 4X4 mi...
The starting point in this note is the charged-lepton mass formula successfully predicting the figure m_\tau = 1776.80 MeV for \tau-lepton mass versus its recent experimental value m_\tau = 1776.82 \...
Political and social activists are rightfully concerned about future generations: whenever a country borrows money, or an environmental situation worsens, this means, in effect, that we impose an addi...
Laser Compton scattering(LCS) can generate Xrays or γrays with high brightness and easy controlled polarization by applying highpeakpower laser pulses to relativistic electron bunches. One of the ...
The Kızıldağ (Hatay) ophiolite is one of the best preserved Neotethyan oceanic lithospheric remnants in southern Turkey. It is represented by, from bottom to top, mantle tectonites, ult...
Wiley is a leading publisher for the scientific, technical, and medical (STM) communities worldwide. Our STM programs encompass journals, encyclopedias, and electronic products in subjects such as the...
In this study, effects of two hericides on pupa formation period, pupa period and number of adults in F1, F2 and F3 generations of Drosophila melnogaster were investigated. 300 ppm concentraiton of 2-...
