Vijayaraghavan and Chowla [2] have proved the following result. If n = 2 or has no primitive root, then there exist suitable reduced residue systems ft, r», • • • , f » and Si, s2, ■ ■ ■ , Sh, where h=in), such that riSi, r2s2, • • • , r^Sh is also a complete residue system (mod n). Since the numbers of a reduced residue system (mod n) form an abelian group with respect to multiplication, it...

It has been shown that phase variation of Sh. sonnei is accompanied by changes in morphology and antigenic structure. Two mutants of the Phase I organism (II(S) and II(R)), which were studied, elaborate somatic antigens which are immunologically identical. The purified lipocarbohydrate-protein antigens of the Phase I and II(S) microorganisms are chemically similar yet immunologically distinct a...

Abstract The electromagnetic (EM) field variations capable of probing the electrical conductivity upper mantle and transition zone have a period range between few hours 1 day. At these periods, dominant source EM signals is ionospheric current system, which has complex spatial temporal structure. A concept global-to-local (G2L) transfer functions can handle spatially by relating global expansio...

The feasibility of unconventional feed for ruminants must be analyzed appropriate use as sources energy or protein that contribute to a sustainable production system addressing concerns about climate change, greenhouse gas emissions, and food security. objective this study was evaluate the nutritive value by-products including bean residue (BR), straw (BS), cassava bagasse (CB), corn (CS), oran...

A collection of 24 hexacoordinate Co(II) complexes was investigated by ab initio CASSCF + NEVPT2 SOC calculations. In addition to the energies spin–orbit multiplets (Kramers doublets, KD) their composition spins is also analyzed, along with projection norm effective Hamiltonian. The latter served as evaluation axial and rhombic zero-field splitting parameters g-tensor components. fulfilment spi...

In most cases authors are permitted to post their version of the article (e.g. in Word or Tex form) to their personal website or institutional repository. Authors requiring further information regarding Elsevier's archiving and manuscript policies are encouraged to visit: The paper by Sousa, Holbrook and Piazza (SH&P) appears to have two distinct aims. First, it advances a number of criticisms ...

Context. Empirical verification of the geometrical concept of homogeneity of the standard relativistic cosmology considering its various definitions of distance and emphasizing that astronomical observations occur along the past light cone. Aims. To present an analysis about the physical consequences of the distinction between the usual concept of spatial homogeneity (SH), as defined by the Cos...

Abstract. A major strong sudden stratospheric warming (SSW) occurred in the Southern Hemisphere (SH) stratosphere 2002 (hereafter referred to as SSW2002), which is one of most unusual winters SH. Following several warmings, polar vortex broke down midwinter. Eastward-traveling waves and their interaction with quasi-stationary planetary played an important role during this event. This study anal...

Abstract Hadley circulation (HC) is a planetary-scale overturning in the tropics that transports momentum, heat, and moisture poleward. In this study, we evaluate strength extent of HC historical future climate simulations Korean Meteorological Administration (KMA) Advanced Community Earth system model (K-ACE), which was recently developed by National Institute Sciences Korea. Compared with rea...
