Research ArticleOpen accessIn the abstractDevelopment and Evaluation of Acaricidal Soap Formulated from Azadirachta indica (Neem) and Carica Papaya (Papaya) Leaf Extracts Using Bio-Assay Guided ApproachAlfredo V. Corpuz, Carmela Montoya Florentino, Ace Danielle C. AveroThe environment, human health, and animals are all at risk as a result of the pervasive use of chemical-based products to control ticks and lice in animals, mostly dogs. This investigation was designed to assess the efficacy and physicochemical properties of an acaricidal soap for canines that was formulated using Azadirachta indica and Carica papaya leaf extracts. The soap was … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 27 Nov 2025 · 3,082 accessesView PDFCite
Research ArticleOpen accessIn the abstractScreening of Bioactive Constituents from the Aerial Parts of Dictamnus dasycarpus Turcz. With Antioxidant, Immunoenhancing, and Anticoagulant PotentialJiaqi Sun, Shiyu Ji et al.The cultivation of Dictamnus dasycarpus Turcz (DdT) is expensive and difficulty associated with growing, making its root bark the only commonly used medicinal part, while other parts are discarded. Therefore, in order to improve the limited utilization of resources, the new medicinal parts were screened from polysaccharide-rich aqueous extracts. The samples were the purified polysaccharides from the aerial part on … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 9 Oct 2025 · 2,018 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Biochar Quality from Palm and Cacao Waste through Variation of Pyrolysis Temperature and Duration as a Soil Amendment MaterialIwan Saputra, Sugeng Prijono et al.Palm and cacao waste are high-quality raw materials for producing quality biochar that enhances soil fertility, provided that the biochar production process takes into account various aspects of pyrolysis. The pyrolysis conditions, such as temperature and duration, significantly impact the quality of the biochar produced as a soil amendment. The type of raw material, pyrolysis temperature, duration, and other conditions … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 27 Jul 2024 · 5,558 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study of Diesel Engine Generator Performance and Emission Characteristics Using a Mixture of Jatropha Oil and Rubber Seed Oil Biodiesels Along a Two-Step TransesterificationFana Gebremedhin Gebremichael, Joao Fernando ChidamoioThis study investigates the performance and emission properties of engine-generator powered using various dual biodiesel mixes prepared from two inedible feedstock jatropha and rubber. Jatropha and rubber oils had high acid values, which were 13.96 and 27.91 mg KOH/g, respectively. Therefore, a two-step transesterification process was conducted to lower the acid value to 0.28 and 0.42 mg KOH/g for jatropha … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 1 Jul 2024 · 5,124 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurvey and Distribution of Plant Parasitic Nematodes on Tomato at Baruasagar in Jhansi (India)Abha Sachan, Rajesh Kumar Pandey, Shailendra Kumar et al.Tomato (Lycopersicon esculentum) is an important high-value vegetable crop and acts as a natural medicine that alleviates the risk of a condition such as cancer and cardiovascular disease. Plant parasitic nematodes are obligate biotrophic feeders that cause the most devastating phytoeconomic damage to tomato cultivation across the globe. Their infection may lead to a spectrum of disorders like stunting, necrosis … …American Journal of Agricultural and Biological Sciences, Vol. 18, Issue 1 · 10 Jan 2024 · 6,816 accessesView PDFCite
