Research ArticleOpen accessEvery word in the titleEffects of Different Concentrations and Applications of Calcium on Storage Life and Physicochemical Characteristics of Papaya (Carica Papaya L.)T.M.M. Mahmud, A. Al Eryani-Raqeeb, S.R. Syed Omar et al.Papaya (Carica Papaya L.) fruits index 2 were treated with 1.5, 2.5 and 3.5% solutions of calcium chloride by dipping and vacuum infiltration (-33 Kpa) or untreated (0%) as control. Effects of these treatments were evaluated on storage life and postharvest quality characteristics of papaya. After 21 days of storage at 13±1°C, the fruits were removed from storage for physicochemical … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 9,652 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleSpatial-Dynamics of Trace Metals Accumulation and Physicochemical Characteristics in Ikpukulu-Ama Creeks, Rivers State, NigeriaDavies Ibienebo Chris, Khang Wen Goh, Davies Imachrist Ibienebo et al.The study examines the spatial-dynamics variability of water parameters and trace metal concentrations between January and June 2023 at the Ikpukulu-Ama sites of the Bonny River, Nigeria. Key parameters analyzed include temperature, salinity, pH, transparency, dissolved oxygen, and trace metals (Ni, Pb, Cd, Cu, Zn) across three sites. The highest temperature, 32.56°C, was recorded at Site 2, indicating potential thermal … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 29 Jul 2026 · 494 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleConcentration and Physicochemical Properties of Chitosan Derivatives Determine the Induction of Defense Responses in Roots and Leaves of Tobacco (Nicotiana tabacum) PlantsAlejandro B. Falcón-Rodríguez, Juan C. Cabrera, Eduardo Ortega, Miguel Ángel Martínez-TéllezProblem statement: The chitosan derivatives promote diverse defensive responses in plants, which are affected by chitosan chemical features and concentration. Glucanase (EC 3.2.1.6), Phenylalanine Ammonia-Lyase (PAL, EC 4.3.1.5) and peroxidase (POD, EC 1.11.1.6) are key enzymes in tobacco defense responses. Thus, the aim of this study was to know the behavior of their enzymatic activity in leaves and roots of … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,263 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsTheoretical Investigation of Two Antiemetic Drugs at DFT LevelKhalil Errahmane Kanouni, Yacine BenguerbaThe geometries and the bonding properties have been predicted for two antiemetic drugs using Density Functional Theory method (DFT). Mulliken population and frontier molecular orbital analysis with the determination of the physicochemical properties was performed using the Amsterdam Density Functional package (ADF). To calculate the exchange-correlation energy, the Generalized Gradient Approximation of Becke-Perdew (GGA-BP) was used. The most important finding … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 14 May 2020 · 11,496 accessesView PDF Cite

InvestigationOpen accessIn the keywordsFreeze Drying of Grape Raw Materials in Red WinemakingGennadiy Vyacheslavovich Semenov, Gennadiy Ivanovich Kasyanov, Ivan Ivanovich Petkov, Irina Stanislavovna KrasnovaThe aim of this research was the development of technology, which is based on the winemaking from freeze dried grape raw materials. Results of research on the drying of Cabernet Sauvignon grapes were shown. The regimes of preparation of grape raw materials and its subsequent freeze-drying are offered, providing the possibility of successful use in the dried state in the … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 3 Aug 2017 · 7,410 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsImpact of Drinking Water Treatment on Poultry Health and Performances: An Experimental StudyCherifa Boumedous, Zouhir Djerrou, Youcef Hamdi PachaThe present study aimed to investigate the impact of water quality on broilers performance. Two flocks of 10 chicks each were separated and maintained in the same poultry barn in Hamma Bouziane (Constantine). The animals were given standard food in the same husbandry conditions.

Research ArticleOpen accessIn the keywordsNon-Alcoholic, Naturally-Carbonated Beverage from Vitis Vinifera Using Saccharomyces Cerevisae Isolated from Cheese WheyHeena Chilana, Sanju Arora, Robinka Khajuria, Loveleen KaurIn the present work a pure yeast culture was isolated from cheese whey and identified by 26S rDNA sequencing as Saccharomyces cerevisiae NRRL Y-12632. This yeast was used to produce low alcoholic self carbonated beverage from grape juice, grape: Kinnow juice (2:1) and grape: Pomegranate juice (2:1) under optimized conditions. The physicochemical properties of 3 days fermented grape: Pomegranate beverage … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 6 Aug 2015 · 7,148 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsRegeneration of Lyes for Cleaning-In-Place (CIP) Processes in Dairies: Comparison of Recycled Potash and Soda Solutions Cleaning PropertiesMarie Furic, Anne Elain, Walid Blel, Olivier SireThe regeneration of lyes for their integration in the dairy CIP was investigated applying an original process combining adsorption/coagulation and flocculation operations. Solutions of potassium hydroxide (KOH) and caustic soda (NaOH) soiled with 1% (v/v) of whole milk were submitted up to twenty successive regeneration cycles. The multiple recycling of the regenerated solutions was found to modify their physicochemical characteristics … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 6 Jul 2015 · 6,624 accessesView PDF Cite
