Humusica 2, article 16: Techno humus systems and recycling of waste
(Elsevier, 2018)Techno humus systems correspond to man-made topsoils under prominent man influence. They may be purposely conceived for supporting agricultural activities or dumping of waste products, sometimes abandoned to an unknown ... -
Hurricane-induced disturbance increases genetic diversity and population admixture of the direct-brooding isopod, Gnathia marleyi
(Springer Nature, 2020)Severe disturbances can substantially alter eco-evolutionary processes and dynamics. While the impacts of catastrophic events on the biophysical attributes of communities are sometimes assessed, their effects on the genetic ... -
Hybrid compounds from thiosemicarbazone and triazole as antidiabetic agents and their antioxidant potentials
(Allied Academies, 2017)Diabetes mellitus is a metabolic disease that threatens and reduces the quality of life. Eight hybrids (1ah) of thiosemicarbozone and triazole were screened for their effects on genes related to type 2 diabetes as well as ... -
Hybrid DFT study of MWCNT/Zr-doped SrTiO3 heterostructure: hydrogen production, electronic properties and charge Carrier mediator role of Zr4+ ion
(Elsevier, 2018)Over the past decade, remarkable efforts have been made to design low-cost, non-toxic, stable and efficient photocatalyst for water splitting. In the present work, an effective alternative approach to enhance hydrogen ... -
Hybrid nuclear plant simulator design requirements to enable dynamic diagnostics of plant operations
(Elsevier, 2017)With nuclear plant full scope simulator technology reaching maturity, the possibility of using its capabilities in expert systems such as online plant diagnostics has become a reality. The effectiveness of plant diagnostics ... -
Hybrid peacekeeping and the United Nations: the case of UNAMID
(Taylor & Francis, 2017)The statutory framework which allows for the United Nations (UN) to conduct peace operations with regional organisations is examined along with the significance and meaning of a hybrid arrangement or agreement. This is ... -

Hybridisation of battery, supercapacitor and hybrid capacitor for load applications with high crest factors: a case study of electric vehicles
(IAES, 2019)This paper proposes a novel topology of hybridizing battery, supercapacitor and hybrid capacitor for optimum utilization of energy in electric vehicles. Hybridization of energy storage has been the theme of much research ... -
Hydration state of the Moss Hylocomium splendens and the Lichen Cladina stellaris governs uptake and revolatilization of airborne α- and γ‑Hexachlorocyclohexane
(American Chemical Society, 2012)The partitioning of α- and γ-hexachlorocyclohexane between air and the moss Hylocomium splendens and the lichen Cladina stellaris were studied under laboratory conditions. After cultivation of the sample material to obtain ... -
Hydrocyclone cut-size estimation using artificial neural networks
(Elsevier, 2016)The hydrocyclone is widely used throughout the mineral processing industry when working with slurries. It is either used for classifying, desliming or dewatering. Hydrocyclones are inexpensive, application-efficient and ... -
Hydroformylation of post-metathesis product using commercial rhodium-based catalysts
(Springer, 2018)The hydroformylation of the post-metathesis product 7-tetradecene using different commercially available homogeneous rhodium-based catalysts has been investigated. The influences of different reaction conditions such as ... -
