Critical analysis of process integration options for joule-cycle and conventional heat pumps
(MDPI, 2020)To date, research on heat pumps (HP) has mainly focused on vapour compression heat pumps (VCHP), transcritical heat pumps (TCHP), absorption heat pumps, and their heat integration with processes. Few studies have considered ... -
Functional losses in ground spider communities due to habitat structure degradation under tropical land-use change
(Wiley, 2020)Deforestation and land‐use change in tropical regions result in habitat loss and extinction of species that are unable to adapt to the conditions in agricultural landscapes. If the associated loss of functional diversity ... -

Report on the INTAV international tephra conference “Crossing New Frontiers: Tephra Hunt in Transylvania”, 24 June-1 July, 2018, Moieciu de Sus, Romania
(International Union for Quaternary Research (INQUA), 2018)The International Focus Group on Tephrochronology and Volcanism (INTAV) held a tephra conference, “Crossing New Frontiers: Tephra Hunt in Transylvania”, at Moieciu de Sus, near Braşov in the southern Carpathian Mountains ... -
Hardware in the loop evaluation of a hybrid heating system for increased energy efficiency and management
(2016)This study presents the tests of a hybrid heating prototype, designed for retrofitting thermal treatment plants like pasteurization, to use hot water and steam in controlled ratios. In the food industry, steam with a ... -
Design of robust total site heat recovery loops via Monte Carlo simulation
(MDPI, 2019)For increased total site heat integration, the optimal sizing and robust operation of a heat recovery loop (HRL) are prerequisites for economic efficiency. However, sizing based on one representative time series, not ... -
The amplitude and origin of sea-level variability during the Pliocene epoch
(Nature Publishing Group, 2019)Earth is heading towards a climate that last existed more than three million years ago (Ma) during the ‘mid-Pliocene warm period’¹, when atmospheric carbon dioxide concentrations were about 400 parts per million, global ... -
Synthesis of a boronic acid anhydride based ligand and its application in beryllium coordination
(Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim, 2019)The synthesis of a boronic acid anhydride‐based ligand containing one three‐ and one four‐coordinated boron atom is presented. This ligand was successfully employed as a tridentate κ¹N,κ²O‐ligand in the coordination of ... -
Advancement in the pressureless sintering of CP titanium using high-frequency induction heating
(Springer, 2019)High-frequency induction heating is applied as an alternative heating source for pressureless sintering of commercially pure Ti powders, aiming to intensify the sintering process. The effects of the process parameters on ... -
Insights on the environmental impacts associated with visible disturbance of ice-free ground in Antarctica
(Cambridge University Press, 2019)The small ice-free areas of Antarctica provide an essential habitat for most evident terrestrial biodiversity, as well as being disproportionately targeted by human activity. Visual detection of disturbance within these ... -
Early Jurassic palaeoenvironments in the Surat Basin, Australia - marine incursion into eastern Gondwana
(Wiley, 2019)Interpretations of palaeodepositional environments are important for reconstructing Earth history. Only a few maps showing the Jurassic depositional environments in eastern Australia currently exist. Consequently, a detailed ... -
Development of an innovative urease-aided self-healing dental composite
(MDPI, 2020)Dental restorative materials suffer from major drawbacks, namely fracture and shrinkage, which result in failure and require restoration and replacement. There are different methods to address these issues, such as increasing ... -
Preparation and tensile properties of guar gum hydrogel films
(Sage, 2019)Guar gum hydrogels may be dried to form polymer films which have the potential for use as biodegradable alternatives to polymers such as low-density polyethylene. In this study, the tensile strength and tensile modulus of ... -
Developments and future insights of using nanofluids for heat transfer enhancements in thermal systems: a review of recent literature
(Springer Science and Business Media LLC, 2019)The twenty-first century is experiencing a wave of technologies and innovations making use of unique features of nanofluids, in applications such as industrial and process heating, air conditioning and refrigeration systems, ... -
The Weibull distribution as an extreme value model for transformed annual maxima
(New Zealand Hydrological Society, 2019)There is no mathematical difference between theoretical extreme value models of maxima and minima because they link to each other by a simple sign reversal transformation. However, other transformations that change sample ... -
The effect of real and virtual construction field trips on students’ perception and career aspiration
(MDPI AG, 2020)To adequately prepare students for engineering practices, it is imperative that institutions adopt innovative methods of teaching, learning, and assessment. One such approach is the use of real field trips (RFT) to ...
