Protective Performance of Coated Reinforcement in Coral Concrete under Dry/Wet Cycling.

The actual protective performance of the coated reinforcement in coral concrete was investigated by measuring the chloride ion diffusion coefficient, electrochemical analysis, and numerical simulation. The test results show that the corrosion rate of coated reinforcement in coral concrete under the action of wet and dry cycles is kept at a low level, and the Rp value is always greater than 250 kΩ·cm during the test period, which is in the uncorroded state and has good protection performance. Moreover, the chloride ion diffusion coefficient D is in accordance with the power function relationship with the wet and dry cycle time, and a time-varying model of chloride ion concentration on the surface of coral concrete is established.

Effects of Small Deviations in Fiber Orientation on Compressive Characteristics of Plain Concrete Cylinders Confined with FRP Laminates.

The effectiveness of concrete confinement by fiber-reinforced polymer (FRP) materials is highly influenced by the orientation of fibers in the FRP laminates. In general, acceptable deviation limit from the intended direction is given as 5° in most design guidelines, without solid bases and reasoning. In this paper, a numerical study using finite element modeling was conducted to assess the effects of small deviations in fiber orientation from the hoop direction on compressive behavior of concrete cylinders confined with FRP.

Effects of Exogenous Nitric Oxide Treatment on Grape Berries Against and Related Enzymes and Metabolites.

Postharvest losses of grape berries caused by the pathogenic fungi and have been widely reported, and nitric oxide (NO) as a plant signaling molecule to control postharvest diseases has recently become an active research topic. This study aimed to investigate the regulatory effect of NO on the interaction between grape berries and fungi. During interactions between grape berries and pathogenic fungi, treatment with 10 mM sodium nitroprusside (SNP, an NO donor) delayed the decline of the physiological quality of the grape berries and had positive effects on the weight loss rate, firmness, and respiration intensity.

An Experimental Study on Non-Destructive Evaluation of the Mechanical Characteristics of a Sustainable Concrete Incorporating Industrial Waste.

Structural materials sustainability is gaining popularity across the globe at present. Reusing natural resources, building, demolition debris, and solid waste are the most apparent tools to make construction more environmentally friendly. Traditional concrete is believed to be less durable, stronger, environmentally friendly, and socially and commercially feasible than industrial waste concrete.

Quantification of rosmarinic acid from different plant species of lower Himalayan region and expression analysis of underlying L-Phenylalanine pathway.

This study adopts a very effective high-performance liquid chromatography (HPLC) technique for the quantitative determination of rosmarinic acid (RA) and PCR-based amplification of biosynthetic key regulators in Isodon rugosus, Daphne mucronata, and Viburnum grandiflorum from the lower Himalayan regions. Rosmarinic acid is engaged in a variety of biological processes and has significant industrial significance. In this study, it was identified from crude methanolic extract using thin-layer chromatography with a standard, and its content was quantified using HPLC without interrupting spikes using a mixture of methanol and deionized water containing acetonitrile (70:30 v/v) and acetic acid (0.

Effect of Carbon Black and Hybrid Steel-Polypropylene Fiber on the Mechanical and Self-Sensing Characteristics of Concrete Considering Different Coarse Aggregates' Sizes.

The effect of combining filler (carbon black) and fibrous materials (steel fiber and polypropylene fiber) with various sizes of coarse particles on the post-cracking behavior of conductive concrete was investigated in this study. Steel fibers (SF) and carbon black (CB) were added as monophasic, diphasic, and triphasic materials in the concrete to enhance the conductive properties of reinforced concrete. Polypropylene fiber (PP) was also added to steel fiber and carbon to improve the post-cracking behavior of concrete beams.

Combination of sodium alginate and nitric oxide reduces browning and retains the quality of fresh-cut peach during cold storage.

Fresh-cut peaches are susceptible to browning when exposed to air. Reducing the browning is important to maintain the quality of the fresh-cut peaches. Nitric oxide (NO) as the signal factor can improve the antioxidant capacity of organisms; sodium alginate (SA) is a natural polysaccharide with good antibacterial and film-forming properties.

Enhancement of storability and antioxidant systems of sweet cherry fruit by nitric oxide-releasing chitosan nanoparticles (GSNO-CS NPs).

Sweet cherries rapidly depreciate in market value owing to decay and the quick loss of fruit quality after harvest. Therefore, optimum postharvest treatment is crucial for maintaining the qualities of cherries during storage. Here, we tested a new method of postharvest treatment by immersing sweet cherries in nitric oxide-releasing chitosan nanoparticles (GSNO-CS NPs), storing them at 0 °C and evaluating fruit quality over time.

Albendazole as an adjuvant to the standard surgical management of hydatid cyst liver.

Background: The treatment options for hydatid cyst liver include non-operative and operative methods. Operative methods include conservative and radical procedures. Non-operative methods include chemotherapy and percutaneous treatment of liver hydatidosis.

Ascaris liver abscess in children.

Background: Liver abscess in childhood is a very challenging subject both for patients and doctors. In India, pyogenic liver abscesses have been found mostly in children, especially in rural areas. Liver abscess due to wandering ascarids is a common complication in children in Kashmir, although it is rare outside.
