Scaling laws of quiet-Sun coronal loops [PDF]
, 2019 We study a series of relations between physical parameters in coronal loops of the quiet Sun reconstructed by combining tomographic techniques and modeling of the coronal magnetic field. We use differential emission measure tomography (DEMT) to determine

The Canadian Journal of Chemical Engineering, EarlyView.Abstract On the centennial of higher education in Chemical Engineering in Mexico, it is pertinent to revisit the key stages that have contributed to its consolidation as a vital discipline for the nation's scientific and technological advancement. Although the initial mission of chemical engineering education was primarily oriented toward the training ...

MALDI-MS argininyl bufadienolide esters fingerprint from parotoid gland secretions of Rhinella arenarum : age, gender and seasonal variation [PDF]
, 2018 In many amphibians, the granular glands can be grouped in special regions forming macroglands. This is the case of toads, characterized by the presence of a pair of parotoid macroglands, strategically located to give protection by poison release in case ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract A streamlined characterization framework (WSPLK) is presented for modelling complex reservoir fluids using cubic equations of state. The key methodological contribution is the introduction of a single global parameter ε directly into Pedersen's boiling‐point correlation, restoring pure‐component calibration and eliminating the need for ...

Acid-Sensing Ion Channels Activated by Evoked Released Protons Modulate Synaptic Transmission at the Mouse Calyx of Held Synapse [PDF]
, 2017 Acid-sensing ion channels (ASICs) regulate synaptic activities and play important roles in neurodegenerative diseases. We found that these channels can be activated in neurons of the medial nucleus of the trapezoid body (MNTB) of the auditory system in ...

Can ISO/IEC 17025 serve as a tool to prevent scientific fraud in chemical research laboratories?
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Scientific fraud has been documented across multiple disciplines, and chemistry is no exception. Recent studies indicate that contamination of materials, methodological errors, and unreliable data, results, or analyses account for over 25% of retracted publications.

1020 steel coated with Ti/TiN by Cathodic Arc and Ion Implantation [PDF]
, 2017 TiN coatings have been widely studied in order to improve mechanical properties of steels. In this work, thin Ti/TiN films were prepared by plasma based immersion ion implantation and deposition (PBII&D) with a cathodic arc on AISI 1020 steel substrates.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Ciudad compacta versus ciudad difusa. Caso de estudio: Valencia, ciudad continua.
III Congreso Internacional ISUF-H. CIUDAD COMPACTA VS. CIUDAD DIFUSA, 2019 Valencia es un “palimpsesto”. Desde su fundación romana hasta nuestros días, ha sabido desarrollarse continuando las huellas de su trazado histórico. Desde aquellos versos de Machado: “Valencia de finas torres...” -que evocaban el perfil de la ciudad representada en los grabados del XVIII-, hasta las esbeltas torres que Jean Nouvel propuso en la ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C
