Thirty-two ambient cured alkali-activated engineered composites (AAECs) were developed by incorporating MgO, multi-walled carbon nanotubes (MWCNTs), reduced graphene oxide (rGO), and polyvinyl alcohol (PVA) fiber with a one-part dry mix technique using powder-based activators/reagents. The effects of material variables, namely binary or ternary combination source materials (fly ash C F ground granulated blast furnace slag ‘GGBFS’), two types reagents varying chemical ratios dosages additives...

Background: Acinetobacter baumannii is an important opportunistic pathogen that causes serious nosocomial infections. Its ability to adhere surfaces, forming biofilms, acquiring genetic materials from unrelated genera making it a dangerous organism causing high morbidity and mortality. Objective: The goal of this study was isolate identify various samples the pattern antibiotic resistance. Methodology: This cross-sectional conducted in Department Microbiology Dhaka Medical College, Dhaka,...

ABSTRACT We report the draft genome of a cefepime-resistant A. baumannii TDU5, isolated from Turag river water in Bangladesh. The strain was serum-resistant and pathogenic. size 3,586,480 bp with 3,429 coding sequences (CDS). isolate harbored multiple antimicrobial resistance genes including bla PER-7 , ADC-52, OXA-91 .

This study presents a comprehensive assessment of the fresh state, rheological, and mechanical properties alkali-activated mortars (AAMs) developed by incorporating magnesium oxide (MgO) nanomaterials. A total 24 AAM mixes with varying content MgO, multi-walled carbon nanotube (MWCNT), reduced graphene (rGO) were following one-part dry mix technique using powder-based activators/reagents. The effects types/combinations source materials (binary or ternary)/reagents, MgO (0 to 5%), MWCNT...

PWM technique can reduce switching and harmonic losses of the inverter. Hybrid inverter utilizes half switches to operate at low-frequency signal other high-frequency loss. But loss heat dissipation among are uneven which reduces system reliability. Three-phase symmetrical hybrid sinusoidal is proposed where all low signals alternatively removes unequal between switches. Switching loss, total distortion SHSPWM don't vary from HPWM. The simulated without with a pie filter in MATLAB/Simulink...

Cynodon dactylon (Poacae) is a well known traditional plant used as folk remedy in treatment of many symptoms and diseases like cramps, measles, tumors, wounds, warts, fever rheumatic affections. In this study, the antimicrobial activity crude extract from three different extraction (hot cold aqueous extraction, methanol extraction) was investigated against some gram positive bacteria (Staphylococcus epidermidis, Bacillus cereus) negative (Escherichia coli, Pseudomonas aeroginosa, Salmonella...

The Tagetes erecta an extensively used medicinal plant is a small shrub, which grows up to 1–2 mm. present study was aimed investigate the antibacterial activity of this common locally available plant. Antimicrobial three confined densities crude extracts (cold aqueous, hot aqueous and methanol extracts) leaves flowers evaluated by disk diffusion method against seven different pathogenic species gram positive negative bacteria. result indicates that leaf flower part showed broad spectrum...

Hybrid power technology plays an important role in the field of energy systems. This can be used with or without a grid by merging renewable and non-renewable sources. study analyses electricity generation through off-grid hybrid technology, which is composed micro-hydro diesel generator remote area Bangladesh. In this investigation, some crucial cases will examined, are optimum turbine placement aid fluid flow simulation using parameters, electric production single unit system unit, cost...

The research concentrated on the corrosion resistance of reinforced self-consolidating concrete (SCC), lightweight SCC (LWSCC), fiber LWSCC (FRLWSCC), Engineered cementitious composite (ECC) and (ECC-SCC/LWSCC) beams. performance corroded beams were analyzed based current measurements, half-cell potential readings, crack pattern/width, rebar mass loss diameter reduction from accelerated tests. Corroded their companion uncorroded tested to failure under four-point loading evaluate...
