Research ArticleOpen accessIn the abstractEnvironmental Impact Assessment of Quarrying Plants: An IRF Kriging Solution to Noise and Airborne Dust MonitoringDario Lippiello, Guido Alfaro Degan, Mario PinzariA geostatistical approach is tested for the assessment of the environmental impact generated by industrial plants on the surrounding areas. To this end, a case study of a tuff quarry in the Italian region of Lazio is presented. The method utilised is Intrinsic Kriging with external drift which allows spatial maps of different hazardous agents like noise and airborne dust … …American Journal of Environmental Sciences, Vol. 15, Issue 1 · 9 Feb 2019 · 7,891 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrasound Imaging of the Testes and Accessory Sex Glands in Male Goat Treated with GnRH During Non-Breeding SeasonHamed T. Elbaz, Emad M. Abdel Razek, Ahmed DawodThe aim of the present study was to determine the effect of GnRH on the measurements of testes, accessory sex glands and testosterone hormonal concentrations during the non-breeding season. Eight mature healthy Egyptian Baladi male goat injected with Buserelin acetate (GnRH analogue) 8μg once weekly for one month. Ultrasonographic measurements of the scrotum and its contents and all accessory sex … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 2 · 15 Apr 2019 · 7,843 accessesView PDFCite
Research ArticleOpen accessIn the abstractProbabilistic Learning Models for Secure E-Commerce Transaction AnalysisAnanth Maria Pushpa, S. SubramaniaanThe tremendous expansion of e-commerce requires well-developed security mechanisms of transactions coupled with cryptography systems. This paper explores how probabilistic learning algorithms can be used to promote fraud and transaction validation in e-commerce systems that are cryptographically secured. A study compared different machine learning models to analyze retail data, including Naïve Bayes, Bayes Network, and Logistic learning. The results showed … …Journal of Computer Science, Vol. 22, Issue 11 · 20 Oct 2026 · 527 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Maize Potato Intercropping and Different Fertilization Methods on Rhizosphere Soil Microorganisms and Yield of PotatoHuanjin Ma, Shengguang Xu et al.A field experiment with three replicates was conducted to explore the effects of maize-potato intercropping and different nitrogen application strategies on rhizosphere soil microorganisms and potato yield. Microbial community analysis was based on relative abundance. Maize-potato intercropping improves land use efficiency, yet how differentiated nitrogen management regulates rhizosphere microecology and potato productivity in this system remains unclear. Clarifying nitrogen-mediated shifts … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 14 Sep 2026 · 814 accessesView PDFCite
Review ArticleOpen accessIn the abstractHuman Activity Recognition at the Edge: A Systematic Review of Machine Learning Models, Deployment Constraints, and Latency Energy Accuracy Trade offsJose Antonio Rojas Guillén, Wini Ebelin Quispe Bautista, Arturo Gamarra MorenoHuman Activity Recognition (HAR) has become a key component of intelligent healthcare monitoring, assisted living, sports analytics, smart environments, and wearable computing. However, the migration of HAR models from cloud-centered architectures to edge, embedded, mobile, and wearable platforms introduces constraints related to computational capacity, memory footprint, battery consumption, inference time, and real-time responsiveness. This study presents a systematic literature review … …Journal of Computer Science, Vol. 22, Issue 8 · 7 Sep 2026 · 601 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Vitamin D Deficiency on Cardio Metabolic Ageing in Middle Aged Adults in India: A Comparative AnalysisSumit Kumar, Adithi K, Shailaja S MoodithayaAdvancing age is accompanied by a gradual deterioration in physiological function, resulting in an increased risk of chronic diseases and early mortality. Growing evidence suggests that inadequate vitamin D status may be associated with unfavourable metabolic and cardiovascular alterations. Nevertheless, information regarding the association of vitamin D status with integrated cardio-metabolic biomarkers of ageing in middle-aged adults is currently limited. … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 3 Sep 2026 · 738 accessesView PDFCite

Research ArticleOpen accessIn the abstractPhosphorus Availability Modulates Bradyrhizobium japonicum’s Impact on Soil Micribial Biomass and Soybean (Glycine max (L.) Merrill) Yield in Lubumbashi Tropical SoilsBen Tshibuyi Kasu-Bandi et al.Tropical soils in sub-Saharan Africa exhibit low fertility, high acidity, and limited Phosphorus (P) availability, a key nutrient for agricultural productivity and the sustainability of cropping systems. This deficiency, exacerbated by the strong fixation of P in acidic soils, not only limits plant growth but also the efficiency of the nitrogen-fixing symbiosis between soybeans (Glycine max (L.) Merrill) and Bradyrhizobium … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 13 May 2026 · 1,991 accessesView PDFCite
