Corrosion inhibition efficiency of heavy alkyl benzene derivatives for carbon steel pipelines in 1 M HCl

open access: yesEgyptian Journal of Petroleum, 2012
The corrosion inhibition process of carbon steel in 1 M HCl by octadecylbenzene sulfonic acid (H) and their three ester derivatives (H1, H2, and H3) were studied. The esters were quaternized by n-butyl bromide to get (H1Q, H2Q, and H3Q).

Effects of non‐host traces on behavioural responses of an egg parasitoid to substrate‐borne semiochemicals in a multi‐herbivore scenario

open access: yesEcological Entomology, EarlyView.
In open arena assays, the response of the egg parasitoid Trissolcus basalis to substrate‐borne semiochemicals left by the host Nezara viridula was affected by the non‐host Spodoptera littoralis. Non‐host larval traces reduced T. basalis residence time spent on walking traces from gravid N. viridula females but did not affect responses to walking traces

The Effect of Traffic Congestion on Labour Investment Efficiency

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT The study examines the effects of headquarters‐city traffic congestion on labour investment efficiency. The results indicate that firms headquartered in congested cities may engage in inefficient labour investment decisions. Further analysis indicates that the inefficiency is associated with both overinvestment and underinvestment in labour ...

Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization

open access: yesThe FEBS Journal, EarlyView.
PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

Use of an Oral Health‐Related Quality of Life Instrument to Measure Unmet Dental Care Needs in Adults With Inherited Bleeding Disorders

open access: yesHaemophilia, EarlyView.
ABSTRACT Introduction Preventive dental care is vital for individuals with bleeding disorders to reduce the need for potentially invasive procedures. Although dental care is a mandated function of U.S. federally supported hemophilia treatment centers (HTCs), access to dental care is widely variable.

Differentiated by Design? Cross‐Border Cooperation in Europe as Differentiated Integration From Below

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract Differentiated integration has become a central concept in contemporary theorizing about European integration, reflecting the increasingly multi‐speed, multi‐tier and multi‐menu nature of integration within the European Union (EU). This research note extends the conceptual lens of differentiated integration to the level of cross‐border regions.

Management of chronic urticaria: Current status and future prospect

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
Chronic urticaria is driven by mast cell activation through autoimmune, inflammatory, and neuroimmune pathways.
