( Elsevier , 2022 , Article Review)In the modern age, the most important and prevailing issue is the monitoring of human health. To address this, several devices have been developed and a need new materials investigated. The idea of textile-based smart ... -
Reconstruction of Compressed Hyperspectral Image Using SqueezeNet Coupled Dense Attentional Net
( MDPI AG , 2023 , Article)This study addresses image denoising alongside the compression and reconstruction of hyperspectral images (HSIs) using deep learning techniques, since the research community is striving to produce effective results to ... -
Redefining the climate niche of plant species: A novel approach for realistic predictions of species distribution under climate change
( Elsevier , 2019 , Article)Climate change is increasingly affecting plant species distributions, in ways that need to be predicted. Here, in a novel prediction approach, we developed the relevant climate niche (RCN) of plants, based on thorough ... -
Reduced fertigation input sustains yield and physiological performance for improved economic returns and cleaner production of greenhouse eggplant
( Elsevier , 2024 , Article)Greenhouse horticulture, a sustainable alternative to conventional horticulture, maximises resource use and return for vegetable production. This study evaluated the impact of varying nutrient solution electrical conductivity ... -
Regional stratigraphy, facies distribution, and hydrocarbons potential of the Oligocene strata across the Arabian Plate and Western Iran
( Springer Verlag , 2019 , Article)Major global events during the Oligocene epoch included a climatic change from warm “greenhouse” to a cooler “icehouse” that was accompanied by the onset of Antarctic glaciation. These events led to decline in water ... -
Relative contribution of plant traits and soil properties to the functioning of a temperate forest ecosystem in the Indian Himalayas
( Elsevier , 2020 , Article)© 2020 Elsevier B.V. Plant-soil interactions are a major determinant of changes in forest ecosystem processes and functioning. We conducted a trait-based study to quantify the contribution of plant traits and soil properties ... -
Remote sensing of desertification and study of temporal variability of aeolian deposits in parts of the Arabian Desert for sustainable development in an arid environment
( Academic Press Inc. , 2023 , Article)Aeolian deposit in part of the Arabian Desert is mapped using ASTER data to understand desertification, land encroachment, and degradation, and to assess agricultural development in arid regions. In this study, the ... -
Remote sensing of inland Sabkha and a study of the salinity and temporal stability for sustainable development: A case study from the West coast of Qatar
( Elsevier , 2021 , Article)The inland sabkha of the Arabian Gulf is important to study for the occurrence of minerals, rocks, soil salinity, and stability of the sabkha due to the high demand for infrastructure and agriculture development region. ... -
Removal of heavy metals from wastewater by aerogel derived from date palm waste
( Elsevier , 2024 , Article)Cellulose that has been sourced from date palm leaves as a primary component was utilised. This cellulose served as the foundational material for the development of an aerogel composite. During this process, MXene (Ti3C2Tx) ... -
Salt tolerance of selected halophytes at the two initial growth stages for future management options
( Springer , 2021 , Article)Scarcity of water and the small area of the agricultural land are considered as the crucial environmental issues challenged the Arabian Gulf countries. In this study, experiments were conducted to identify the salt tolerance ... -
Scale dependence of species–area relationships is widespread but generally weak in Palaearctic grasslands
( Wiley , 2021 , Article)Questions: Species–area relationships (SARs) are fundamental for understanding biodiversity patterns and are generally well described by a power law with a constant exponent z. However, z-values sometimes vary across spatial ... -
Scale effects on the relationships between land characteristics and ecosystem services- a case study in Taihu Lake Basin, China
( Elsevier , 2020 , Article)© 2020 Elsevier B.V. It is generally recognized that marginal changes in landscape characteristics can influence multiple ecosystem services, but the causal relationships involved are still very unclear due to lack of ... -
