This research work evaluated a straight forward approach for pulp bio-bleaching by growing the xylanase producing microorganism (Bacillus pumilus) directly onto the soda pulp and then comparing the ...results of this approach with effect of the extracted xylanase enzyme from the same microorganism. The kappa number for the bacterial treated pulp sample decreased by 26.4% whereas after the enzymatic treatment only 10.3% decrease was found. Physical properties of the paper also improved more significantly in case of bacterial treated pulp samples (52.3% increase in the tear factor, 5% improvement in tensile strength) as compared to the paper formed after enzymatic treatment of pulp (27.57% increase in tear factor, 2.9% increase in tensile strength). The results suggest a novel method of pulp bleaching by direct growth of B. pumilus which is much simpler and time efficient method. The paper quality improved considerably following this approach in comparison to the extracted enzyme.

Coronary embolism (CE) is a rare cause of acute ST-elevation myocardial infarction (STEMI). Atrial fibrillation (AF), left ventricular thrombus, septic emboli from infective endocarditis, myxoma, and ...paradoxical embolism can induce emboli in coronary arteries.
Here we present a case of anterior wall STEMI secondary to paroxysmal AF in a 60-years-old female with a previous history of right-sided ischemic stroke.
The major criteria for diagnosis of coronary embolism include (1) non-atherosclerotic wall of coronary vessels under angiography; (2) concomitant involvement of multiple sites; (3) histological proof of venous thrombus; (4) imaging by echocardiography/CT/MRI showing intra-cardiac thrombus. The minor criteria include (1) <25% stenosis of other vessels supplying to infarct-free myocardium; (2) atrial fibrillation history; (3) risk factors like (prosthetic valve, bacterial endocarditis, patent foramen ovale, atrial septal defect, dilated cardiomyopathy).
Our case highlights the importance of cardiac embolus as a diagnosis in a patient with a history of stroke secondary to atrial fibrillation as a cause of acute STEMI and its management.
•Cardioembolism is an underappreciated etiology of the acute coronary syndrome in the patient with atrial fibrillation.•Cardiac embolus may be in a patient with the history of stroke secondary to atrial fibrillation as a cause of acute STEMI.
Management of dementia is very crucial. Nonpharmacological methods (NPM) are well appreciated and encouraged to be used as first-line treatment for managing elderly patients with dementia (PwD). The ...present case reports aimed to share the strategies of NPM for managing PwD. NPM requires a structured blueprint to record, follow-up, and monitor the outcomes. A structured proforma has been developed in the department. After getting all the basic information from the patient, needed assessments are being done by the concerned team member to identify and rate the level of severity of the problem, and specific NPM strategies are being provided. Concerted efforts give positive results; knowledge and understanding about the illness help the caregiver in managing the patient. No negative impact has been reported; NPM is a cost-effective approach and therefore should be studied on a larger level to provide evidence from India and prove its efficacy.
To minimize losses likely to occur due to Corynespora leaf spot, systemic and contact fungicides and formulation of bacterial antagonists like Bacillus subtilis DTBS-5, B. amyloliquefaciens DSBA-11, ...and Pseudomonas fluorescens DTPF-3 talc-based formulations were evaluated to manage the disease. Though mancozeb has the lowest EC50 value of 1250.54 ppm it was not efficient in the field experiment. In addition, dual culture assay to determine the efficacy of bacterial antagonists against C. cassiicola, B. amyloliquefaciens DSBA-11 effectiovely reduced growth of C. cassiicola. In the field experiments conducted during Kharif 2019 and 2020, two sprays with Azoxystrobin 23 SC@ 0.5 ml lit

were found most effective in reducing disease severity by 57.7% and 67.7% respectively during Kharif 2019 and 2020. Azoxystrobin 23 SC treatment resulted in a maximum increase of 281.5 kg in grain yield followed by Pseudomonas fluorescens DTPF-3 264.7 kg and Bacillus subtilis DTBS-5 248.9 kg yield.

A potential strategy to solve the issues of energy efficiency, sustainability, and occupant comfort in contemporary architecture has emerged in responsive building components and systems. Among these ...elements, adaptable facades are essential for quickly adapting to changing climatic conditions and enhancing building performance. This chapter briefly introduces adapted facades and smart building materials like insulation, phase change materials, recycled material sustainable wood glass-based materials, water-efficient fixtures, and components that have evolved as game-changing aspects that incorporate technology into the very structure of our built environment. These materials can respond autonomously to environmental changes, optimize energy use, and improve occupant comfort because they have embedded sensors, cutting-edge control systems, and connected networks. The applications and advantages of smart building materials are examined in this chapter, including increased energy efficiency, improved occupant well-being, and the potential for developing sustainable, intelligent structures. Stakeholders in the construction industry may sculpt a future of sustainable and resilient buildings that meet the changing needs of society by comprehending and embracing smart building materials and components.
