This paper reports a new simple four-dimensional（4 d） hyperjerk chaotic system. The proposed system has only one stable equilibrium point. Hence, its strange attractor belongs to the category of hidden attractors. The proposed system exhibits various dynamical behaviors including chaotic, periodic, stable nature, and coexistence of various attractors. Numerous theoretical and numerical methods are used for the analyses of this system. The chaotic behavior of the new system is validated using circuit implementation. Further, the synchronization of the proposed systems is shown by designing an adaptive integrator backstepping controller. Numerical simulation validates the synchronization strategy.

Six apparently healthy male buffalo calves aged between 6 months to one year with body weight range of 70 - 140 Kg were used in the present investigation. One animal was used for pilot trial for this group. Five calves were randomly taken into this group. The Eschrechia coli endotoxin infused i/v @5 mg/kg BW/hr for 3 hours to all the animals caused symptoms of restlessness, respiratory distress, snoring, diarrhea, profuse salivation along with the significant fall in systolic, diastolic, pulse and mean arterial venous pressure, hypoproteinemia at 1, 2 & 3 hour and hypoglycemia at 3rd hour i.e., end of endotoxin infusion. Respiration was increased significantly during endotoxin infusion at 2nd & 3rd hour and even afterwards till the end of the observation period i.e. 7 hrs. The treatment with hypertonic saline solution, flunixin meglumine and blood raised (p th, 6th & 7th hour respectively i.e., till the end of the observation period. There was no significant effect on Central Venous pressure (CVp) and body temperature as measured from rectum.

This paper presents an investigation on depo- sition of Inconel-625 using laser rapid manufacturing （LRM） and plasma transferred arc （pTA） deposition in individual and tandem mode. LRM has advantages in terms of dimensional accuracy, improved mechanical properties, finer process control, reduced heat input and lower thermal distortion, while pTA scores more in terms of lower initial investment, lower running cost and higher deposition rate. To quantify the clubbed advantages and limitations of both processes, these were studied individually and in tandem. A number of samples were deposited at different process parameters like power, scan speed, powder feed rate. They were subjected to tensile test, adhesion-cohesion test, impact test and micro hardness measurement. The results of individual tests showed the comparable mechanical prop- erties with i20% variation. The mixed dendritic-cellular and dendritic-columnar microstructures were respectively observed for LRM and pTA deposits with a distinct inter- face for the case of tandem deposition. The interface strength of tandem deposits was evaluated employing adhesion-cohesion test, and it was found to be （325 i 35） Mpa. The study confirmed the viability of LRM and pTA deposition in tandem for hybrid manufacturing.

The static and energy-dependent nucleus–nucleus potentials are simultaneously used along with the Wong formula for exploration of fusion dynamics of 8^16O＋50^112,116,120Sn reactions. The role of internal structure degrees of freedom of colliding pairs, such as inelastic surface vibrations, are examined within the context of coupled channel calculations performed using the code CCFULL. Theoretical calculations based on the static Woods–Saxon potential along with the one-dimensional Wong formula fail to address the fusion data of 8^16O＋50^112,116,120Sn *** discrepancies can be removed if one uses couplings to internal structure degrees of freedom of colliding ***, the energy-dependent Woods–Saxon potential model（EdWSp model） accurately describes the sub-barrier fusion enhancement of 8^16O＋50^112,116,120Sn reactions. Therefore, in sub-barrier fusion dynamics, energy dependence in the nucleus–nucleus potential governs barrier modification effects in a closely similar way to that of the coupled channel approach.

This article analyzes the fusion dynamics of loosely bound and stable projectiles with Zr-target isotopes within the context of the coupled channel approach and the energy-dependent Woods-Saxon potential model （EdWSp model）. In the case of the 2SSi＋90Zr reaction, the coupling to the inelastic surface excitations results in an adequate description of the observed fusion dynamics while in case of the 2Ssi ＋ 94Zr reaction, the coupling to collective surface vibrational states as well as the neutron （multi-neutron） transfer channel is necessary in the coupled channel calculations to reproduce the below-barrier fusion data. However, the EdWSp model calculation provides an accurate explanation of the fusion data of 2Ssi＋ 90,94Zr reactions in the domain of the Coulomb barrier. In the fusion of the 6Li＋90Zr reaction, the inclusion of the nuclear structure degrees of freedom recovers the observed sub-barrier fusion enhancement but results in suppression of the above barrier fusion data by 34% with respect to the coupled channel calculations. Using EdWSp model calculations, this suppression factor is reduced by 14% and consequently, the above-barrier fusion data of 6Li＋90Zr reaction is suppressed by 20% with reference to the EdWSp model calculations. Such fusion suppression at above-barrier energies can be correlated with the breakupof the projectile （6Li） before reaching the fusion barrier, as a consequence of low binding energy.
