Non-Fermi-liquid behavior at anti-ferromagnetic quantum critical point in heavy fermion system Ce(Cu1−x_{1-x}Cox_x)2_2Ge2_2

Polycrystalline samples of Ce(Cu$_{1-x}$Co$_x$)$_2$Ge$_2$ were investigated by means of electrical resistivity $\rho$($T$), magnetic susceptibility $\chi$($T$), specific heat $C$$_p$($T$) and thermo electric power $S$($T$) measurements. The long-range antiferromagnetic (AFM) order, which set in at $T$$_N$ = 4.1 K in CeCu$_2$Ge$_2$, is suppressed by non-iso-electronic cobalt (Co) doping at a critical value of the concentration $x$$_c$ = 0.6, accompanied by non-Fermi liquid (NFL) behavior inferred from the power law dependence of heat capacity and susceptibility i.e. $C$($T$)/$T$ and $\chi$($T$) $\propto$ $T$$^{-1+\lambda}$ down to 0.4 K, along with a clear deviation from $T$$^2$ behavior of the electrical resistivity. However, we have not seen any superconducting phase in the quantum critical regime down to 0.4 K.Comment: 8 pages, 11 figure

Investigation of ion induced bending mechanism for nanostructures

Ion induced bending is a promising controlled technique for manipulating nanoscale structures. However, the underlying mechanism of the process is not well understood. In this letter, we report a detailed study of the bending mechanism of Si nanowires (NWs) under Ga+ irradiation. The microstructural changes in the NW due to ion beam irradiation are studied and molecular dynamics simulations are used to explore the ion–NW interaction processes. The simulation results are compared with the microstructural studies of the NW. The investigations inform a generic understanding of the bending process in crystalline materials, which we suggest to be feasible as a versatile manipulation and integration technique in nanotechnology

On the Laminar Flow of Viscous Incompressible Fluid Through a Pipe Bounded by a Hyperbola and a Line

The present paper deals with laminar flow of a viscous incompressible fluid through a pipe bounded by a hyperbola and a line. The expressions, for the discharge of flux, maximum velocity and the coefficients k, k' as introduced by Boussinosqu (Bateman et al 1932) have been obtained. Graphs representing variations of velocity within the pipe give the final result

A brief report on older people's experience of cybercrime victimization in Mumbai, India

As internet penetration increases in Lower and Middle Income Countries (LMIC), more older people are now conducting financial transactions online and using social media to stay in touch with family and friends. We discuss concerns that existing financial regulations and controls in India may afford older people insufficient protection from cybercrime, using qualitative interviews from our recent study exploring older people’s experiences of cybercrime in Mumbai

Some new Black Mildew, Asterina, collected from North -Western U.P.

During the morphotaxonomic studies of Black Mildews from Himalayan foothills of North-Western Uttar Pradesh, 20 species of Asterina were collected. Out of these, Asterina syzygicola collected on Syzygium jambolanum and Asterina heniana collected on Syzygium henianum are described and illustrated as new to scienc

Entrance channel dependence in compound nuclear reactions with loosely bound nuclei

The measurement of light charged particles evaporated from the reaction 6,7Li+6Li has been carried out at extreme backward angle in the energy range 14 - 20 MeV. Calculations from the code ALICE91 show that the symmetry of the target-projectile combination and the choice of level density parameter play important roles in explaining the evaporation spectra for these light particle systems. In above barrier energy region the fusion cross-section is not suppressed for these loosely bound nuclei.Comment: 2 pages, 1 figur
