High early strength concrete incorporating waste derived nanomaterials for sustainable construction.

This paper contributes to the expanding knowledge base on nanomaterial-enhanced cementitious composites, offering valuable insights for developing high-performance, sustainable concrete solutions. The study assessed the effects of three different types of nanomaterials-nano clay (NC), nano silica (NS), and nano cellulose (NCel)-on the compressive strength of high-early-strength concrete (HESC) through both experimental studies and a 2 factorial design. Incorporating nanomaterials into the HESC matrix led to a decrease in workability, with NCel demonstrating the least impact on this property across all studied replacement percentages.

An impedimetric approach for determination of ammonium using silver/poly-1-aminoanthraquinone/carbon paste electrode.

Here, we present the electrochemical determination of ammonium in water samples, emphasizing the importance of accurate and precise assessment of its concentration. The modified electrode used in this study was fabricated through the anodic polymerization of 1-aminoanthraquinone (1-AAQ) and deposition of silver particles into a carbon paste electrode. The fabrication process involved cyclic voltammetry in a 0.

Antimycotic prophylaxis with multispecies probiotics against oral candidiasis in new complete denture wearers: A randomized clinical trial.

Statement Of Problem: Changes in the oral microbiota of new complete denture wearers are the main cause of oral candidiasis. The drawbacks associated with traditional antimycotic therapies, especially drug resistance, have led to the search for potent therapeutic and prophylaxis agents with less harmful effects, including probiotics. However, investigation of the prophylaxis and preventive effects of probiotics on new complete denture wearers are lacking.

Synergistic optical sensing: Selective colorimetric analysis of copper in environmental and biological samples.

A groundbreaking optical sensing membrane has been engineered for the accurate assessment of copper ions. The pliable poly(vinyl chloride) membrane is formulated through the integration of sodium tetraphenylborate (Na-TPB), 4-(2-hydroxy-4-nitro azobenzene)-2-methyl-quinoline (HNAMQ), and tri-n-octyl phosphine oxide (TOPO), in conjunction with o-nitrophenyl octyl ether (o-NPOE). The sensor membrane undergoes a thorough investigation of its composition to optimize performance, revealing that HNAMQ serves a dual role as both an ionophore and a chromoionophore.

A novel design for prosthetic ear guiding device: A technical note.

This article describes a newly designed Prosthetic Auricular Guide (PAG) that allows for accurate planning and positioning of both the auricular implants and the prosthetic auricle. The design aims to provide a cost-effective guiding device for more esthetic ear prostheses which is the patient's main concern. Along with determining the best clinically accepted position of the ear, the device can be used while taking CBCT which allows for the integration of the clinically approved position with the remaining bone for accurate planning of implant positions.

A custom auricular implant healing abutment: A dental technique.

Skin overgrowth is a complication that hinders bone-anchored prosthetic ear rehabilitation. In order to accurately transfer the healing skin for prosthetic reconstruction, this article introduces a custom-made autopolymerizing acrylic resin auricular cap (button) through indirect pick up of the metal housing. The caps are secured during the healing stage to shape the skin, preventing surgical edema, swelling, and skin overgrowth in patients suffering from keloid reactions from covering the implant abutments.

Improving the Thermal Performance and Energy Efficiency of Buildings by Incorporating Biomass Waste into Clay Bricks.

Excessive urban construction is primarily driven by uncontrolled population growth, which has serious consequences for the environment, energy, cost, and human life in general when building materials are massively used. In terms of energy and economic efficiency, buildings that make use of sustainable construction materials and technologies perform better. This is because building in an eco-friendly way results in less waste.

A highly selective bulk optode based on 6-{4-(2,4-dihydroxy-phenyl)diazenyl)phenyl}-2-oxo-4-phenyl-1,2-dihydro-pyridine-3-carbonitrile incorporating chromoionophore V for determination of nano levels of cadmium.

A novel optical sensor has been fabricated for highly accurate, simple and selective determination of nanomolar levels of cadmium ions. The sensor depends on the interaction of 6-{4-(2,4-dihydroxyphenyl)diazenyl)phenyl}-2-oxo-4-phenyl-1,2-dihydropyri-dine-3-carbonitrile (DDPODC) with Cd(II) in plasticized (2-nitrophenyloctyl ether) (o-NPOE) polyvinylchloride (PVC) membrane incorporating chromoionophore V as a lipophilic H-selective indicator. It would seem that the higher Cd(II) concentration, the lower absorbance of chromoionophore V in the membrane at 668 nm, whereas the absorbance at 586 nm increased.

Untapped potential of 2D charge density wave chalcogenides as negative supercapacitor electrode materials.

Two-dimensional (2D) materials have opened new avenues for the fabrication of ultrathin, transparent, and flexible functional devices. However, the conventional inorganic graphene analogues are either semiconductors or insulators with low electronic conductivity, hindering their use as supercapacitor electrode materials, which require high conductivity and large surface area. Recently, 2D charge density wave (CDW) materials, such as 2D chalcogenides, have attracted extensive attention as high performance functional nanomaterials in sensors, energy conversion, and spintronic devices.

Biochemical Characterization and Antimicrobial Activity against Some Human or Phyto-Pathogens of New Diazonium Heterocyclic Metal Complexes.

String of vanadium (IV), zirconium (IV), palladium (II), platinum (IV) and uranium (VI) chelates of 2-cyano-2-[(2-nitrophenyl)hydrazono]thioacetamide (Cnphta) were prepared and characterized by physicochemical, spectroscopic and thermal analyses. The formulae of the isolated solid complexes were assigned as [VO(Cnphta) (H O)]SO  ⋅ 5H O (1), [ZrO(Cnphta) (H O)]Cl  ⋅ 4H O (2), [Pd(Cnphta) ]Cl (3), [Pt(Cnphta) Cl ]Cl (4) and [UO (Cnphta) ](NO )  ⋅ 5H O (5). The infrared assignments clearly showed that Cnphta ligand coordinated as a bidentate feature through the hydrazono nitrogen and the thioacetamide nitrogen for V(IV), Zr(IV) and U(VI) but displayed different behavior for Pd(II) and Pt(IV).

Are models better read on paper or on screen? A comparative study.

Is it really better to print everything, including software models, or is it better to view them on screen? With the ever increasing complexity of software systems, software modeling is integral to software development. Software models facilitate and automate many activities during development, such as code and test case generation. However, a core goal of software modeling is to communicate and collaborate.

Acute and subacute toxicity of on rats.
