Reconfigured single- and double-diode models for improved modelling of solar cells/modules.

Proper modeling of PV cells/modules through parameter identification based on the real current-voltage (I-V) data is important for the efficiency of PV systems. Most related works have concentrated on the classical single-diode model (SDM) and double-diode model (DDM) and their parameter extraction by various metaheuristic algorithms. In order to render more accurate and representative modeling, this paper adds a small resistance in series with the diodes in SDM and DDM.

Synergy of Hydrophilic Properties and Antibacterial Inhibition in Polyvinyl Alcohol Nanofibrous Mats Loaded With Croton Bonplandianum Baill Leaf Extract.

The antibacterial nanofibrous mat is crucial in biomedicine as it enhances infection control, expedites wound healing, and mitigates health hazards by decreasing antibiotic usage. A novel synergistic antibacterial and hydrophilic nanofibrous mat successfully fabricated by solution electrospinning from polyvinyl alcohol (PVA) incorporated Croton bonplandianum Baill (CBB) leaves extract. Antioxidant-enriched leaf extract of the CBB plant was integrated with PVA in varying proportions of 30% (CBB-30), 40% (CBB-40), and 50% (CBB-50) to manufacture antibacterial nanofibrous mat.

Causes and Consequences of Delayed Presentation of Muscle Invasive Urinary Bladder Carcinoma.

Lag times for the diagnosis and treatment of urinary bladder cancer are generally longer which reduces the chances of achieving cures. This study was carried out at the Urology Department of Bangabandhu Sheikh Mujib Medical University, Dhaka and a Urology Center in a private hospital in Dhaka, Bangladesh from July 2007 to June 2008 on patients of newly diagnosed muscle invasive bladder carcinoma. This study was intended to assess the delay encountered by the patients and its consequences in the process of diagnosis and treatment of bladder cancer.

Deconstruction of Alkali Lignin and Lignocellulosic Substrates by DY1 Isolated from Rotten Wood.

The present study reports the ability of a fungal isolate DY1, obtained from rotten wood, to degrade alkali lignin (AL) and lignocelluloses in an efficient manner. The efficiency of degradation was monitored by measuring the percentage of decolorization and utilizing GC-MS for identifying degradation products at different time intervals (10, 20, 30, and 40 days). The optimal degradation of alkali lignin (AL) was achieved at 0.

Microbial enzymes as powerful natural anti-biofilm candidates.

Bacterial biofilms pose significant challenges, from healthcare-associated infections to biofouling in industrial systems, resulting in significant health impacts and financial losses globally. Classic antimicrobial methods often fail to eradicate sessile microbial communities within biofilms, requiring innovative approaches. This review explores the structure, formation, and role of biofilms, highlighting the critical importance of exopolysaccharides in biofilm stability and resistance mechanisms.
