Halloysite nanotube and chitosan polymer composites: Physicochemical and drug delivery properties
( Editions de Sante , 2022 , Article)Advancement in healthcare requires sophisticated and safe drug delivery systems. An ideal drug delivering system should be non-toxic, therapeutically inert, and be able to deliver a wide range of drugs. Here, we report ... -
Halloysite Nanotube as Multifunctional Component in Epoxy Protective Coating
( American Chemical Society , 2016 , Article)The current research explores the use of halloysite nanotube as a multifunctional filler in epoxy coating for carbon steel. Epoxy monomer loaded halloysite was incorporated into epoxy coating along with amine hardener ... -
Halloysite nanotubes and halloysite-based composites for biomedical applications
( Elsevier , 2021 , Article)Novel biomaterials for diagnostics and therapeutics of biomedical issues have been considered using biomedical science and health care. Halloysite nanotubes (HNTs) are naturally occurring aluminosilicate clay. Because of ... -
Halobacteria-Based Biofertilizers: A Promising Alternative for Enhancing Soil Fertility and Crop Productivity under Biotic and Abiotic Stresses—A Review
( MDPI , 2023 , Other)Abiotic and biotic stresses such as salt stress and fungal infections significantly affect plant growth and productivity, leading to reduced crop yield. Traditional methods of managing stress factors, such as developing ... -
Halogen-free flame-retardant compounds. Thermal decomposition and flammability behavior for alternative polyethylene grades
( MDPI AG , 2019 , Article)The effect of six halogen-free flame retardant (FR) formulations was investigated on the thermal stability of two low-density polyethylenes (LDPE) and one linear low-density polyethylene (LLDPE), by means of thermogravimetric ... -
Halophytes and Soil Salinity in Qatar
( Qatar University , 2002 , Article)Saline soils cover approximately 6% of the land in Qatar. Halophytes are common along the coastal areas and inland salt flats and wetlands, where saline water is available in their natural habitats permanently or periodically. ... -
Halophytes as important sources of antioxidants and anti-cholinesterase compounds
( Springer International Publishing , 2021 , Book chapter)Halophytes are plants adapted to high salinity, and they are common in many places around the world where environmental conditions are inconvenient for the growth of conventional plants. Normally, plants exposed to harsh ... -
Halul and Sharao islands, offshore Qatar: Remnants of the great infracambrian Hormuz Salt basin
( springer link , 2004 , Article)Halul and Sharao islands, offshore Qatar, are among more than 200 islands in the Gulf region, which are believed to have formed by salt diapirism sourced in the Infracambrian Hormuz Salt Series. The islands are composed ... -
Handcrafted features with convolutional neural networks for detection of tumor cells in histology images
( IEEE Computer Society , 2016 , Conference Paper)Detection of tumor nuclei in cancer histology images requires sophisticated techniques due to the irregular shape, size and chromatin texture of the tumor nuclei. Some very recently proposed methods employ deep convolutional ... -
Handling Big Data in Modern Healthcare
( Oxford University Press , 2016 , Article)The constant growth of medical knowledge and the increases in specialization in clinical practice have created a significant need to share and access patient information with speed and efficiency. However, current ... -
Handling data uncertainties in event tree analysis
( Elsevier B.V. , 2009 , Article)Event tree analysis (ETA) is an established risk analysis technique to assess likelihood (in a probabilistic context) of an accident. The objective data available to estimate the likelihood is often missing (or sparse), ... -
Handoff-aware cross-layer assisted multi-path TCP for proactive congestion control in mobile heterogeneous wireless networks
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)Multi-Path TCP (MPTCP) is a new evolution of TCP that enables a single MPTCP connection to use multiple TCP subflows transparently to applications. Each subflow runs independently allowing the connection to be maintained ... -
