Catalysis and allostery in bacterial ATP phosphoribosyltransferases

The FEBS Journal, EarlyView.
ATP phosphoribosyltransferase (ATPPRT) catalyses the first reaction of L‐histidine biosynthesis. L‐Histidine allosterically inhibits ATPPRT to regulate this energy‐intensive pathway in histidine‐synthesising organisms, such as bacteria, archaea and plants.

Natural disaster risk salience and the strategic appointment of directors with sustainability expertise

Journal of Financial Research, EarlyView.
Abstract This article examines how salient sustainability risks from near‐miss natural disasters influence board composition. Using a difference‐in‐differences design, I find that firms located in counties neighboring disaster‐affected areas significantly increase the presence of directors with sustainability expertise following the disaster.

Disasters, Dictators, and Donors: The Impact of Foreign Aid on Economic Activity (Mis)Reporting

Review of Development Economics, EarlyView.
ABSTRACT This paper examines how governments manipulate economic data to secure more foreign disaster aid. By using nighttime lighting as a reliable measure of economic activity, we make two key findings: (1) foreign disaster aid is positively linked to a country's understatement of its gross domestic product, indicating a deliberate strategy to ...

DETERMINATION OF THE LEVEL OF OVERVOLTAGE IN THE SECONDARY CIRCUITS OF SUBSTATIONS WHEN LIGHTNING IMPULSE VOLTAGE IS DISTRIBUTED IN HIGH-VOLTAGE BUSES

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2017
Lightning voltage impulse due to the waves of storm surge rolling out the high voltage line to a substation causes current to flow in the buses that, due to magnetic effect, induces overvoltage in the secondary circuit.
