Biochar Influences On Phytochemical Composition And Expression Genes Of Curly Kale At Different Treatment Times, Joyce Dedei Anteh, Esraa Almugrabi, Antonina Mostyakova, Olga Timofeeva

Turkish Journal of Botany

his study examined the effect of biochar application to the soil at different times on the phytochemical composition (phenolic compounds, carotenoids, vitamin C, sugars, proteins, MDA, and antioxidant activity) and expression of HCT, F3’H and CHS genes (which are involved in the accumulation of phenolic compounds) in cabbage kale (Brassica oleracea L. var. acephala). Biochar was prepared from chicken manure, using the method of rapid pyrolysis at a temperature of 400 °C. The retention time at the maximum temperature was 4 h, and the heating rate was 10 °C min–1. The biochar fertilizer was applied to 5–7 day-old kale seedlings …

Novel Physically‑Crosslinked Caffeine And Vitamin C‑Loaded Pva/ Aloe Vera Hydrogel Membranes For Topical Wound Healing: Synthesis, Characterization And In‑Vivo Wound Healing Tests, Elbadawy Kamoun, Elbadawy A. Kamoun

Nanotechnology Research Centre

Novel physically-crosslinked PVA membranes blended with Aloe vera extract were fabricated by solution-casting method. Physically-crosslinking process is depending on the rearrangement of PVA chains forming intermolecular hydrogen bonding with removal of water molecules using propanol as a stabilizing agent. The structure of crosslinked membranes was characterized by FT-IR, SEM, TGA, and XRD analyses and confirmed via gel faction and swelling ratio studies. Caffeine and vitamin C loaded-PVA/Aloe vera membranes were bio-assessed in terms of their impact on the wound healing using Wistar albino rats as an animal model. In vitro evaluation includes protein adsorption showed that the fabricated membranes improved …

Permeable Concrete Barriers To Control Water Pollution: A Review, Rehab O. Abdel Rahman, Ahmed M. El-Kamash, Yung-Tse Hung

Civil and Environmental Engineering Faculty Publications

Permeable concrete is a class of materials that has long been tested and implemented to control water pollution. Its application in low-impact development practices has proved its efficiency in mitigating some of the impacts of urbanization on the environment, including urban heat islands, attenuation of flashfloods, and reduction of transportation-related noise. Additionally, several research efforts have been directed at the dissemination of these materials for controlling pollution via their use as permeable reactive barriers, as well as their use in the treatment of waste water and water purification. This work is focused on the potential use of these materials as …

Green Catalyst For Clean Fuel Production Via Hydrodeoxygenation, Selva Bi̇lge Yücel, Yusuf Osman Donar, Samed Ergenekon, Beyza Özoylumlu, Ali̇ Sinağ

Turkish Journal of Chemistry

The development of new fuel sources to replace nonrenewable fossil fuels has received substantial attention due to the ongoing demand for fossil fuels. Biomass and raw waste materials are crucial sources to produce suitable alternative fuels instead of nonrenewable fuels and offer a greener approach. Therefore, improving the fuel properties of biooils produced from the thermochemical conversion of biomass and raw waste materials is critical as it is used as an alternative to nonrenewable fuel. Developing an economical and eco-friendly method to produce sustainable and renewable oil by improving biooil containing large amounts of phenolic compounds has become imperative. One …

Presence And Abundance Of Antibiotic Resistance Genes At An Organic Goat Dairy Farm, Janice Marie Parks, Noah Askew, Jack Woodrow Creagh-Grave, Gyorgyi Nyerges

International Journal of Undergraduate Research and Creative Activities

How does the use of antibiotics in animal husbandry impact antibiotic resistance genes (ARGs) and integron prevalence? This article examines the prevalence of nine ARGs (OXA-2, tetB, tetG, blaCMY-2, ereB, NDM, ermB, sul1, and sul2) and two class one integron sequences (intI1 and CS) at an organic goat dairy farm. To provide insight on how antibiotic use is contributing to the abundance of ARGs and integrons outside of where they are used, we made a comparison between our findings and the prevalence of ARGs and integrons at conventional farms from previously published studies. Samples were collected from an organic goat …

Are Plant–Soil Feedbacks Caused By Many Weak Microbial Interactions?, Julia K. Aaronson, Andrew Kulmatiski, Leslie E. Forero, Josephine Grenzer, Jeanette M. Norton

Wildland Resources Student Research

We used high-throughput sequencing and multivariate analyses to describe soil microbial community composition in two four-year field plant–soil feedback (PSF) experiments in Minnesota, USA and Jena, Germany. In descending order of variation explained, microbial community composition differed between the two study sites, among years, between bulk and rhizosphere soils, and among rhizosphere soils cultivated by different plant species. To try to identify soil organisms or communities that may cause PSF, we correlated plant growth responses with the microbial community composition associated with different plants. We found that plant biomass was correlated with values on two multivariate axes. These multivariate axes …

Wastewater Treatment Using Encapsulated Chabazite In Polyvinyl Alcohol-Sodium Alginate Hydrogel Biofilm Carriers, Susieanna Nevada Persaud

USF Tampa Graduate Theses and Dissertations

Nitrogen discharge from wastewater is a global issue and with increased urbanization as well as industrialization, it has become even more essential to develop more efficient wastewater treatment systems. The dominant form of nitrogen in wastewater is ammonium. Biological oxidation of ammonium to nitrite and nitrate is the first step in biological nitrogen removal processes. If left untreated, nitrogen can cause toxicity to aquatic life, unsafe changes in water quality, and eutrophication.

Biofilm carriers can help to improve the efficiency of traditional activated sludge wastewater treatment systems by reducing operating costs and reducing hydraulic retention time. Biofilm carriers also promote …

Shah, Gul Afshan Khan, Sadaf Sarfraz, Jibran Iqbal, Aneeqa Batool, Ahmad Jwuiyad, Shabnam Shahida, Changseok Han, Monika Wawrzkiewicz

All Works

This study focuses on investigating and comparing the influence of the surface functional groups and chemical matrices of macroporous resin on the Cr(III) exchange mechanism. The results discussed herein indicate that sulfonic resin removed Cr(III) ions with faster kinetics than carboxylic resin. Equilibrium was established within 15 and 7 min for the carboxylic and sulfonic resins, respectively, with a 99.5% removal efficiency at 333 K. The Langmuir exchange capacity was observed to be higher for the sulfonic resin (1.5 mmol∙g−1) than the carboxylic resin (0.80 mmol∙g−1) at 333 K. The adsorption isotherms obtained for the carboxylic and sulfonic resins were …

Rock and Soil Mechanics

The Central Plains are located in an area that experiences seasonal freeze-thaw cycles, which can have significant effects on the soil structure of soil relics. To determine if lime-metakaolin (L-MK) is a feasible alternative to natural hydraulic lime (NHL) for earth site restoration work, tests were conducted using lime, metakaolin and silty sand from the site as main raw materials. Mass loss, unconfined compressive strength and splitting tensile strength tests were carried out on L-MK improved silty sand soil undergoing different numbers of freeze-thaw cycles to study its strength characteristics in depth. X-ray diffraction (XRD) thermogravimetry (TG), and scanning electron …

Eggshell-Alginate Composites (Eacs) As Eco-Friendly Adsorbents For Rhodamine B Uptake From Aqueous Solutions, Rusnadi Rusnadi, Mar’Atus Sholihah, Nurrahmi Handayani, Muhammad Ali Zulfikar

Karbala International Journal of Modern Science

The contamination of wastewater by Rhodamine B (RhB) poses a significant environmental concern due to its negative impacts on aesthetics, ecosystems, and human well-being. This study successfully synthesized eco-friendly egg-shell-alginate composites (EACs) as adsorbents by combining alginate solution, eggshell powder, and a 2% CaCl2 solu-tion. Characterization techniques including FTIR, SEM, TGA, and SAA were employed to analyze the EACs. FTIR analysis revealed characteristic absorption peaks corresponding to -OH groups, C=O groups, C-O groups, and the pres-ence of CO32-. The structural analysis confirmed the physical mixture of functional groups from eggshells and alginate, resulting in a homogeneous EACs mixture. TGA analysis …
