    Abstract We report a comparative study of a single plasma and a colliding laser produced plasma, investigated using a Faraday cup. An enhancement in ion emission and stagnation is observed in colliding plasma plume compared to single plasma plume. We observed that fast ion generation in laser ablated plasma can be achieved at large laser intensity on to the target. As laser intensity increases ionic yield increases for both colliding and single plume and at a fixed laser intensity ionic yield decreases with increase in ambient pressure. The double peak structure is observed in the ion signal at large fluence where the peaks correspond to fast and slow species. A Faraday cup composed of nine collectors is used to measure the spatial/angular distribution of ion of expanding plasma plume. Ionic yield is found to be larger in the colliding plasma plume than the single plasma plume at all spatial/angular positions.

    Abstract Many efforts have been made to enhance the hydrokinetic turbines’ energy efficiency, extracting the energy from the flowing water in the canal and river. Savonius hydrokinetic turbine is one of the turbines producing mechanical power output using renewable energy sources of flowing water. It has good starting characteristics but has low energy efficiency. In the present investigation, an attempt is made toward the enhancement of the energy efficiency and load-carrying capacity of the Savonius turbine. The two dual-rotor Savonius turbine designs with deflector plates are proposed termed as Dual Rotor with Diverging Deflector Plate (DR-DDP) and Dual Rotor with Converging Deflector Plate (DR-CDP). The investigations are carried out with numerical simulations. The experiments are also performed for the validation of the methodology adopted in the presented numerical simulations. The results indicate the improved performance of the turbine units with both deflector plate designs. The power coefficient with the Savonius turbine unit’s investigated design is enhanced from 0.135 of the conventional turbine to 0.16 with DR-DDP, and that up to 0.20 with DR-CDP.

    Abstract Background: COVID-19 screening protocols rapidly evolved as a result of changing Centers for Disease Control and Prevention (CDC) and California Department of Public Health (CDPH) recommendations. These protocols led to operational improvements at one large academic medical centre using change management methods explained in Kotter's 8-stage change model.
    Methods: We reviewed all iterations of clinical process maps for identifying, isolating and assessing COVID-19 infections in paediatric and adult populations within one emergency department (ED) from 28 February 2020 to 5 April 2020. We incorporated CDC and CDPH criteria for the various roles of healthcare workers in ED patient assessment.
    Results: Using Kotter's 8-stage change model, we outlined the chronological evolution of basic screening criteria, as well as how these were reviewed, modified and implemented during the onset and through the time of greatest uncertainty of COVID-19 in the USA. Our results demonstrate a successful creation, and subsequent execution, of rapidly changing protocols across a large workforce.
    Conclusion: We effectively applied a business change management framework to the hospital management response during a pandemic; we share these experiences and challenges to inform and guide future operational decision making during times of rapid change.

    Abstract Biological enzymes are multifunctional macromolecules that can perform hundreds of reactions simultaneously. An enzyme must possess specific characteristics to meet industrial needs, such as stability over a wide pH and temperature range and high specific activity. A phytase and xylanase mixture is generally added to poultry feed to improve the bird's health and productivity. Despite this, animal farmers have noticed no difference in productivity, and a leading cause is the high temperature at which feed is pulverized, which inactivates enzymes. A thermo-stable enzyme system can overcome these hitches. Commonly, coatings and immobilization reduce losses caused by physical-chemical factors in feed processing and digestion. To this end, we engineered the multifunctional xylanase-phytase domains on a single polypeptide fused by a helical linker. First, the ideal linker sequence was chosen by computing each selected linker's root mean square deviation (RMSD). The selected helical linker provides sufficient structural flexibility for substrate binding and product release evaluated by molecular docking and molecular dynamic simulation studies. Furthermore, a domain-domain interaction has stabilized the bridging partners, attaining the thermal optima for xylanase and phytase at 90 °C. Even at the above-optimal temperature (100 °C), the recombinant PLX was relatively stable and retained 64.2% and 59.2% activity for xylanase and phytase, respectively, when surveyed for ten hours. So far, to this date, this is the highest degree of thermostability achieved by any recombinant phytase or xylanase.Communicated by Ramaswamy H. Sarma.

    Abstract Background: Incidence of sternal dehiscence, wound infection, and mortality are prevalent following sternotomy. Bone wax is widely used over the sternal edges for augmenting hemostasis. This study evaluated the clinical equivalence of Truwax
    Methods: The primary endpoint of this prospective (May 2022-April 2023), parallel-group, two-arm, randomized, single-blind, multicenter study was to evaluate the proportion of subjects having sternal dehiscence within 26 weeks of median sternotomy closure. Secondary endpoints assessed the average time to hemostasis on sternum sides, bone wax properties, number of dressing changes, sternal bone instability (clinically/chest radiography), pain, perioperative/postoperative complications, blood and blood products used, duration of intensive care unit (ICU)/hospital stay, reoperations, time taken to return back to work and normal day-to-day activities, subject satisfaction and quality of life (QoL), and adverse events. A probability of <0.05 was considered significant.
    Results: No incidence of sternal dehiscence or postoperative complications was witnessed. Time to hemostasis, bone wax properties, number of dressing changes, sternal stability, pain, blood and blood products used, duration of ICU/hospital stay, reoperations, time taken to return back to normal day-to-day activities and to work, and subject satisfaction and QoL were comparable between Truwax
    Conclusion: Truwax
