Hydration of C3A with Calcium Sulfate Alone and in the Presence of Calcium Silicate [PDF]

open access: yes, 2011
Tricalcium aluminate (C3A) is one of the main constituents of Portland cement. Even though it represents less than 10% of the total composition, its strong reaction with water can lead to a rapid setting, called flash set.

Observations and numerical simulations of a valley‐exit wind in the Alpine Bolzano basin

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The evolution and spreading of the nocturnal valley‐exit wind flowing from the Isarco Valley into the Bolzano basin, in the Italian Alps, are found to be influenced by the basin temperature stratification. Measurements and high‐resolution simulations show that a cold‐air pool favors an upward trajectory of the flow at the exit of the valley.

Time profile for the production of C3a and C5a. [PDF]

open access: yes, 2016
(A) The response generated for C3a shows a lag phase that is followed by an accelerated production phase. In 60 minutes, the amount of C3a produced is 108 times greater than that of C5a. (B) Zoom-in of panel (A) to show the time profile of C5a.

Unlocking n‐alk‐1‐ynes conformers: Quantum “trigger finger” versus “stiff joint” conformations

open access: yesSmart Molecules, EarlyView.
Quantum chemical analysis reveals the unique function of n‐alk‐1‐yne terminus as a Quantum “Trigger Finger,” exhibiting two near‐isoenergetic conformers (Cs ${\mathrm{C}}_{s}$and C1 ${\mathrm{C}}_{1}$) locked by a symmetric high barrier. This contrasts with the lower asymmetric barrier of the conventional asymmetric “Stiff Joint” alkyl chain.

Activation of complement by hemodialysis membranes: Polyacrylonitrile binds more C3a than cuprophan [PDF]

open access: yes, 1990
Activation of complement by hemodialysis membranes: Polyacrylonitrile binds more C3a than cuprophan. Conventionally, complement activation by hemodialysis membranes has been determined by measuring fluid phase C3a.

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

open access: yesStructural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

Complement-derived anaphylatoxin C3a regulates in vitro differentiation and migration of neural progenitor cells [PDF]

open access: yes, 2009
Anaphylatoxin C3a is a third complement component (C3)-derived peptide, the multiple functions of which range from stimulation of inflammation to neuroprotection. In a previous study, we have shown that signaling through C3a receptor positively regulates

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

open access: yesVIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...

The wolf is back! Non‐consumptive effects of the return of a large carnivore on the use of supplementary feeding sites by roe deer

open access: yesWildlife Biology, EarlyView.
Understanding how prey species tradeoff predation risk and resource acquisition is particularly important for advancing our knowledge of predator–prey relationships. We investigated this by studying the use of concentrated anthropogenic resources, namely supplementary feeding sites, by roe deer Capreolus capreolus before and after grey wolf Canis lupus
