Merger of Bank of Karad Ltd. (BOK) with Bank of India (BOI): A Case Study

In an increasingly globalized and competitive world, it is imperative that all institutions not only follow global practices, but also that they are globally competitive, efficient and sound. In the corporate world it is said if you can’t beat your competitor then go with them i.e. merge your company with your rival or take them over. So all it boils down to is the survival of the fittest. This process helps in attaining greater market share, acquiring additional brands, cannibalizing competing brands, realizing improved infrastructure, creating new synergies, and capitalizing on efficiencies and economies of scale or to globalize in the shortest span of time. A banking merger is just the same as the merger of two companies except that it involves banks. Mergers and Acquisitions (M&A) in the banking sector may be in the form of amalgamation, absorption, consolidation, acquisition or takeover. The important point in the bank merger is that banking activities of the participants will always be regulated.  The present research paper delineates the effects of M&A on the Financials of the Merger of Bank of Karad Ltd. (BOK) with Bank of India (BOI) before and after merger. For this purpose various variables namely, capital, deposits, investments, advances, interest earned, interest paid, total income, total expenditure and net profit have been identified. In the analysis of variables figures for four year prior to merger and figures of variables for four years after the merger have been taken. Figures prior to merger are the total of value of variables of both amalgamating bank (the bank which loses its identity) and amalgamated bank (the bank which continues its existence). The result of regression equation has been found effective after merger of BOI and BOK from the point of view of capital, deposits, investments, advances,  fixed assets, interest earned, total income, net profit and total assets. In the case of interest expenditure and total expenditure result of regression equation has been found ineffective. The Null Hypothesis is rejected in all variables except interest expenditure. Key Words: Merger, Acquisition, Capital, Deposits, Investments, Advances, Fixed Assets, Interest Earned, Interest Paid, Total Income, Total Expenditure, Net Profit and Total Asset

Impact of hydrostatic pressure on superconductivity of Sr0.5La0.5FBiS2

We report the impact of hydrostatic pressure (0-1.97GPa) on superconductivity of recently discovered 2K superconductor Sr0.5La0.5FBiS2. Resistivity under pressure measurements are performed by using HPC-33 Piston type pressure cell with Quantum design DC resistivity Option. The superconducting transition temperature (Tc) is increased by 5 fold to around 10K with just above 1GPa pressure, which remains nearly unaltered for studied higher pressures of up to 1.97GPa. The fivefold increase in Tc of Sr0.5La0.5FBiS2 with just above 1GPa pressure suggests very strong electron correlations in these systems and the same calls for the attention of solid state physics community.Comment: 11 pages text + Figs: Five fold increase in Tc with Just above 1GP

Magnetotransport studies of FeSe under hydrostatic pressure

The discoveries of iron-based superconductors with relatively high transition temperature are under intense experimental and theoretical investigation. Here we present magnetotransport measurements on FeSe superconductor under hydrostatic pressure. We show that in Fe-deficient tetragonal FeSe binary compound, the onset of superconducting transition is almost doubled under 1.98GPa pressure and the estimated upper critical field of 26.7Tesla is increased to 47.5Tesla.Comment: Short MS: 8 pages Text + Figs.

Appearance of bulk Superconductivity under Hydrostatic Pressure in Sr0.5RE0.5FBiS2 (RE = Ce, Nd, Pr and Sm) compounds

We report the appearance of superconductivity under hydrostatic pressure (0.35 to 2.5GPa) in Sr0.5RE0.5FBiS2 with RE = Ce, Nd, Pr and Sm. The studied compounds, synthesized by solid state reaction route, are crystallized in tetragonal P4/nmm space group. At ambient pressure though the RE = Ce exhibit the onset of superconductivity below 2.5K, the Nd, Pr and Sm samples are not superconducting down to 2K. With application of hydrostatic pressure (up to 2.5GPa), superconducting transition temperature is increased to around 10K for all the studied samples. The magneto-transport measurements are carried out on all the samples with maximum Tc i.e., at under 2.5GPa pressure and their upper critical fields are determined. The new superconducting compounds appear to be quite robust against magnetic field but within Pauli paramagnetic limit. The new superconducting compounds with various RE (Ce, Nd, Pr and Sm) belonging to Sr0.5La0.5FBiS2 family are successfully synthesized for the first time and superconductivity is induced in them under hydrostatic pressure.Comment: 17 pages text + Figs: First report on Sr0.5(Ce/Nd/Pr/Sm)0.5FBiS2 new compounds superconducting under pressur

Hydrostatic Pressure Studies on Parent Phase SrFBiS2 of BiS2-based Superconducting Family

In the present work, we measure the temperature dependent electrical resistivity from 300K down to 2K under applied hydrostatic pressure of upto 2.5GPa for SrFBiS2, which is the parent compound for the BiS2 based superconductors. Though the normal state resistivity of the compound decreases with pressure, the same is not superconducting down to 2K under applied pressure of up to 2.5Gpa.Comment: 4 pages text + Figs. First report related to pressure effect on SrFBiS

Specific heat of robust Nb2PdS5 superconductor

We report specific heat under different magnetic fields for recently discovered quasi-one dimensional Nb2PdS5 superconductor. The studied compound is superconducting below 6 K. Nb2PdS5 is quite robust against magnetic field with dHc/dT of -42 kOe/K. The estimated upper critical field [Hc2(0)] is 190 kOe, clearly surpassing the Pauli-paramagnetic limit of 1.84Tc. Low temperature heat capacity in superconducting state of Nb2PdS5 under different magnetic fields showed s-wave superconductivity with two different gaps. Two quasi-linear slopes in Somerfield-coefficient as a function of applied magnetic field and two band behavior of the electronic heat capacity demonstrate that Nb2PdS5 is a multiband su-perconductor in weak coupling limit with deltagamma/deltaTc=0.9.Comment: 4 pages text Figs.

High Field (up to 140kOe) Angle Dependent Magneto Transport of Bi2Te3 Single Crystals

We report the angle dependent high field (up to 140kOe) magneto transport of Bi2Te3 single crystals, a well-known topological insulator. The crystals were grown from melt of constituent elements via solid state reaction route by self-flux method. Details of crystal growth along with their brief characterization up to 5 Tesla applied field was reported by some of us recently [J. Magn. Mag. Mater. 428, 213 (2017)]. The angle dependence of the magneto-resistance (MR) of Bi2Te3 follows the cos Theta function i.e., MR is responsive, when the applied field is perpendicular (tilt angle Theta = o and/or 180) to the transport current. The low field (10 kOe) MR showed the signatures of weak anti localization (WAL) character with typical cusp near origin at 5 K. Further, the MR is linear right up to highest applied field of 140 kOe. The large positive MR are observed up to high temperatures and are above 250 and 150 percent at 140 kOe in perpendicular fields at 50 K and 100 K respectively. Heat capacity CP(T) measurements revealed the value of Debye temperature to be 135 K. ARPES (angle resolved photoemission spectroscopy) data clearly showed that the bulk Bi2Te3 single crystal consists of a single Dirac cone.Comment: 13 Pages text + Figs... Letter - Mat. Res. Ex

PdTe a 4.5K Type II BCS Superconductor

We report on the structure and physical properties of bulk Palladium Tellurium superconductor, which is synthesized via quartz vacuum encapsulation technique at 750 C. The as synthesized compound is crystallized in hexagonal crystal structure. Magnetization and Magneto-transport measurements provided the values of lower and upper critical field to be 250 and 1200 Gauss respectively at 2 Kelvin. The Coherence length and GL parameter are estimated from the experimentally determined upper and lower critical fields, which are 45 nm and 1.48 respectively. The jump in Cp(T) at Tc is found to be 1.33 and the Debye temperature and electronic specific heat constant are 203 Kelvin and 6.01mJ/mole-K2 respectively.Comment: 13 pages Text + Figs: Accepted in Sup.

Impact of Cr-O hyrbidization in ACrO3 (A=La, Y): A Theoretical Investigation

Electronic properties of spin polarized antiferromagnetic ACrO3 (A = La, Y) are explored with Hubbard Model using Density Functional Theory (DFT). These two isostructural systems are investigated using the different Hubbard energy and analyzed the hybridization of chromium 3d orbitals and oxygen 2p orbitals and the change in energy band gaps against the Hubbard energy. The bond length and bond angle affect significantly the orbital contributions of Cr-3d and O-2p electrons for both the system. We noticed that the Cr-O hybridization affects the orbital degeneracy and is substantiated with partial density of states. These results emphasize the contribution of Hubbard energy in correlated electron systems
