The efect of temperature on the elastic, thermophysical and mechanical properties of VNx (0.76≤x≤1.00) epitaxial layers has been investigated using Coulomb and Born–Mayer potentials approach up to second nearest neighbor. The elastic constants and its allied properties (Bulk, Shear, Poisson's ratio and Young’s modulus) are analyzed to provide insights into the mechanical behavior of VNx (0.76≤x≤1.00) transition-metal nitrides using second-order elastic constants (SOECs). SOECs are used to measure the temperature deviation of ultrasonic velocities along the crystal’s z axis. The temperature variation of Debye average velocity and thermal relaxation time are calculated along same orientation. Thermal conductivity has been observed to be the main contributing factor to the temperature-dependent behavior of ultrasonic attenuations with phonon–phonon interaction. Depending on G/B ratios, the nitride groups are attributed to brittle and ductile behavior in the future. Including all epitaxial layers, the estimated melting temperatures are in better agreement with those calculated with B and C11 and have highest strength and highest harness. Transition metal nitrides have unusual chemical and physical properties, which are commonly used in industrial felds that require working at temperatures.

Purpose: The posterior cruciate ligament (PCL) presents commonly with avulsion fractures of its tibial attachment. An avulsion fracture of the PCL, if not surgically fixed, may lead to secondary changes in the knee joint. Various fixation techniques have been explored with use of lag screws, steel wires, absorbable screws, suture anchors and straddle nails. The purpose of this study was to evaluate the clinical and functional outcome of open reduction and internal fixation of tibial avulsion injuries of the PCL using cannulated cancellous screws. Materials and Methods: We performed open reduction and internal fixation using cannulated cancellous screws in 14 patients (mean age, 33.9 years) with isolated PCL avulsion injuries. Patients with a duration of injury more than 12 weeks were excluded. The minimum follow-up period was 12 months. Results were assessed radiologically and clinically. Final functional outcome was assessed using the Lysholm knee scoring system. Results: The average follow-up period was 13.5 months. At the final follow-up, all 14 patients achieved fracture union. The average flexion was 121.7°±9.2° with full extension achieved in all patients. Mild instability (1+) was noted in 4 patients. The Lysholm functional score was excellent in 11 patients, good in 2 patients and fair in 1 patient with an average score of 97±7.6. Conclusions: Stable early fixation for PCL avulsion injuries with early controlled mobilization provided excellent to good results. However, fixation should not be discouraged for late-presenting patients because good to fair results can be achieved in such cases.

Progress in bioremediation of pesticide residues in the environment
Balendu Shekher Giri,Sachin Geed,Kumar Vikrant,Sang Soo Lee,Ki-Hyun Kim,Suresh Kumar Kailasa,Meththika Vithanage,Preeti Chaturvedi,Birendra Nath Rai,Ram Sharan Singh 대한환경공학회 2021 Environmental Engineering Research Vol.26 No.6
The increasing use of various pesticides (e.g., organophosphate, organochlorine, carbamates, and pyrethroid) has helped to improve agricultural productivity by minimizing the potential crop losses associated with insect attacks. Owing to their highly recalcitrant nature, most pesticides and their residues often accumulate in the environment to exert deleterious effects on human health and various ecosystems. Among a variety of remediation options, biological approaches have attracted a widespread attention for the treatment of pesticide in soil/water systems due to their environmentally benign nature. In this regard, this review article was organized to highlight the recent advancements in the application of various bioremediation approaches for the degradation/removal of pesticides from soil/water matrixes along with the catabolic capacity of microorganisms. Our discussions were expanded further to emphasize identification of specific bacterial communities/strains, such as Bacillus sp. and Pseudomonas sp. This review is expected to provide an overview of the modern biotechnological methodologies along with the associated merits and hurdles for the effective abatement of pesticides.
