Experimental Flexural Strength of Reinforced Beam and Reactive Powder Concrete with Bendrat Fiber (2024)

Reactive powder concrete is a new type of concrete that has ultra-high compressive strength, the components of which are very fine powders that have high silica content. Reactive powder concrete has high compressive strength and ductility, which has the potential to replace steel materials in construction work, and has a very large opportunity for construction materials in Indonesia. In this study, 3 types of strength tests were carried out, namely compressive strength tests, splitting tensile t

Flexural response of vertically cast steel fiber reinforced concrete members (2024)

Abstract The presence of the short steel fibers dispersed uniformly in concrete improves its inherent flaws and makes it a versatile structural material. The improvement in material properties depends upon the alignment of the fibers in concrete members caused during their casting; those aligned along the principle tension trajectory of the beams are most efficient among all the fibers present therein and other fibers control their shear response. An attempt is made to quantify the effec

Differential alteration of fMRI signal variability in the ascending trigeminal somatosensory and pain modulatory pathways in migraine (2021)

AbstractBackgroundThe moment-to-moment variability of resting-state brain activity has been suggested to play an active role in chronic pain. Here, we investigated the regional blood-oxygen-level-dependent signal variability (BOLDSV) and inter-regional dynamic functional connectivity (dFC) in the interictal phase of migraine and its relationship with the attack severity.MethodsWe acquired resting-state functional magnetic resonance imaging from 20 migraine patients and 26 healthy controls (HC).

Cerebro-Cerebellar Networks in Migraine Symptoms and Headache (2022)

The cerebellum is associated with the biology of migraine in a variety of ways. Clinically, symptoms such as fatigue, motor weakness, vertigo, dizziness, difficulty concentrating and finding words, nausea, and visual disturbances are common in different types of migraine. The neural basis of these symptoms is complex, not completely known, and likely involve activation of both specific and shared circuits throughout the brain. Posterior circulation stroke, or neurosurgical removal of posterior f

Uranium capture from aqueous solution using Palm-waste based activated carbon: sorption kinetics and equilibrium (2023)

Abstract In this research, we examined the effectiveness of adsorbents derived from commercially available palm kernel shell bio-char (PBC), as well as palm shell carbon that was activated through treatment with H2SO4 (PBC-SA) and ZnCl2 (PBC-Zn). Our primary objective was to enhance the adsorption capabilities of carbon materials and develop efficient sorbents for the removal of uranium ions from aqueous solutions. To gain insight into the characteristics of these materials, we employed

Hierarcal porous polystyrene-based activated carbon spheres for CO2 capture (2021)

Abstract Activated carbon spheres with high specific surface area and hierarcal porous texture were prepared from polystyrene-based macroreticular resin spheres by air pre-oxidization and steam activation. The as-prepared carbon spheres had a specific surface area of 1274.95 m2 g− 1, total pore volume of 1.09 cm3 g− 1 and micropore volume of 0.47 cm3 g− 1. Moreover, these carbon spheres showed a hierarcal porous texture composed of ultrafine micropores (0.5-1 nm), micropores (1–2 nm), me

Herbicide pyrazosulfuron ethyl induces genotoxicity, cell cycle alterations and apoptosis in tilapia (Oreochromis mossambicus) (2022)

Abstract Fishes are excellent subjects for the study of the mutagenic and carcinogenic potential of contaminants present in water. Herbicides are one of the toxic contaminants that cause lethal effects in fish. In this context, the present study was designed to study the sub‐lethal toxic effect (low dose [LD] 25 mg/L, medium dose‐50 mg/L, and high dose [HD] 100 mg/L) of a commonly used herbicide, pyrazosulfuron ethyl (PE), on erythrocytes of tilapia. The ge

Effect of Replacing Fish Oil with Palm Oil on Growth Performance and Survival of Nile Tilapia (Oreochromis niloticus) (2025)

High cost and limited availability of fish oil (FO) in aquafeeds have prompted the search for alternative lipid sources. Palm oil (PO), a widely available and stable vegetable oil, may serve as a viable replacement in tilapia diets. This study investigated the effect of partially replacing fish oil (FO) with PO on the growth performance, feed utilisation, and survival of Nile tilapia cultured in cages. A 16-week feeding trial with four experimental diets was formulated by replacing FO with 0% (T
