Research ArticleOpen accessEvery word in the titleThe Effects of Seasonal Variations on Typha capensis and Heliconia psittacorum in the Remediation of Heavy Metals from Soil and WaterWiafe Samuel, Buamah Richard, Owusu MichaelDifferent plant species have been used in the remediation of different heavy metals. The performance of a macrophyte to remediate heavy metals may be dependent on a lot of factors which may include water chemistry, metal solubilityand temperature. The objective of this research was to ascertain the effects of seasonal variations on the remediation of heavy metals. To this end,two … …American Journal of Applied Sciences, Vol. 15, Issue 12 · 31 Jan 2019 · 7,787 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEffect of Seasonal Temperature on the Genotypic Variability of Flowering Duration in Pearl Millet (Pennisetum glaucum) in NigerSani Daouda Ousmane, Mouhamadou Mounkaila Boureima, Maman Nassourou Lawali et al.Heat stress is a major contributor to crop losses worldwide. Millet [Pennisetum glaucum (L.) R. Br.] is a staple crop for inhabitants of arid and semi-arid regions of the world, due to its extraordinary adaptation to drought and high temperatures. Climate change points to an overall increase in temperature, the effect of which on crop growth and productivity remains to … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 30 Nov 2022 · 6,125 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReclamation of Irrigated Lands and Improvement of the Groundwater Regime Under Vertical Drainage OperationBalzhan Amanbayeva, Raushan Dzhaisambekova, Alexander Basmanov et al.The aim of the study was to identify patterns of seasonal groundwater-level fluctuations and assess the effectiveness of vertical drainage in regulating the reclamation regime of saline lands in Kazakhstan. The methods included monitoring-well observations, calculation of seasonal amplitudes, Student’s t-test, the Mann-Whitney U test, and Pearson correlation analysis. Before the growing season, groundwater occurred at a depth of 1.5-1.7 … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 608 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImplementing a Hybrid VMD–BiTCN–BiGRU Architecture With Intelligent Optimization for Agricultural Commodity Price Prognostication in Gujarat MarketsJignesh Hirapara, Ratnesh Kumar Namdeo, Ankit Kumar Dubey et al.In the agricultural sector, the prices of pulses require adequate forecasting to plan farming activities, store and market, and guide policy-making. However, the pulse price series is highly volatile, seasonal, nonstationary, and nonlinear, and thus conventional linear time series models are not necessarily very effective. In the suggested framework, the raw price data series is decomposed using Variational Mode Decomposition … …Journal of Computer Science, Vol. 22, Issue 7 · 1 Aug 2026 · 1,021 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSpatio-Temporal Anomaly Detection in Groundwater Electrical Conductivity Using a Hybrid Framework of Isolation Forest and AutoencoderEunji Lee, Seunghyun Lim, Seojun Lee, Abhijit DebnathMonitoring groundwater quality is vital for environmental safety and resource sustainability. This study combines Isolation Forest and Autoencoder models to detect anomalies in Electrical Conductivity (EC) and temperature, using monthly data collected in South Korea between 2006 and 2023. Linear regression and the Mann-Kendall test reveal a weak, episodic downward EC trend. Seasonal decomposition indicates annual cyclicality, while residual analysis … …Journal of Computer Science, Vol. 22, Issue 1 · 14 Feb 2026 · 1,918 accessesView PDF Cite
