AVOIDING FIRST-YEAR UNIVERSITY CHEMISTRY TEXTBOOKS’ MISREPRESENTATIONS IN THE TEACHING OF SPONTANEOUS REACTIONS

open access: yesQuímica Nova, 2015
This paper summarizes the misrepresentations related to Gibbs energy in general chemistry textbooks. These misrepresentations arise from a problem in the terminology textbooks use. Thus, after reviewing the proper definition of each of the terms analyzed,

Naturalism and Moral Expertise in the Zhuangzi [PDF]

open access: yes, 2017
This essay will examine scholarly attempts at distilling a proto-ethical philosophy from the Daoist classic known as the Zhuangzi. In opposition to interpretations of the text which characterize it as amoralistic, I will identify elements of a natural ...

DFT (B3LYP) COMPUTATIONAL STUDY ON THE MECHANISMS OF FORMATION OF SOME SEMICARBAZONES [PDF]

open access: yesChemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2016
Thermodynamic and kinetic mechanisms of forming six semicarbazones have been investigated computationally by DFT B3LYP method. All the reactions proceed via two transitions and include two consecutive steps: bimolecular and unimolecular.

Birds and Beasts in the Zhuangzi, Fables Interpreted by Guo Xiang and Cheng Xuanying

open access: yesReligions, 2019
Birds and beasts often appear in the Zhuangzi, in fables and parables meant to be read analogically as instructions for human thought and behavior. Whereas the analogical significance of some fables is obvious, in others it is obscure and in need of ...

On Time chez Dummett [PDF]

open access: yes, 2014
I discuss three connections between Dummett's writings about time and philosophical aspects of physics. The first connection (Section 2) arises from remarks of Dummett's about the different relations of observation to time and to space.

PBF‐LB/M of Ti‐6Al‐4V: High‐Pressure Solution Treatment and Aging for Applications in a Sustainable Aerospace

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.

Large population and long-term behavior of a stochastic binary opinion model

open access: yes, 2019
We propose and study a stochastic binary opinion model where agents in a group are considered to hold an opinion of 0 or 1 at each moment. An agent in the group updates his/her opinion based on the group's opinion configuration and his/her \emph ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.
