Early Postoperative Outcome of Continuous Heparin Infusion versus Intermittent Intravenous Heparin after Initial Bolus Dose during Off-Pump Coronary Artery Bypass Surgery: An Eminent Time worthy Study.

Heparin is an anticoagulant used invariably in all cardiac surgery. Heparin dosing and its reversal were determined by monitoring activated clotting time (ACT). Intermittent heparin dosing after initial bolus dose is widely practiced to maintain ACT level 200-300 seconds in Off-pump coronary artery bypass surgery (OPCAB).

A new ground electronic state potential energy surface of HeLiH+: Analytical representation and investigation of the dynamics of He + LiH+ (v = 0, j = 0) → LiHe+ + H reaction.

An improved global potential energy surface (PES) for the electronic ground state of the HeLiH+ system is reported. The data points are calculated at the full configuration-interaction level of theory and extrapolated to the complete basis set limit. The fitting procedure implements a combination of neural network and Aguado-Paniagua functional forms to fit the ab initio data points.

Synergy of {Co(HO)} with a Polyoxometalate Leads to Aqueous Homogeneous Hydrogen Evolution: Experiments and Computations.

In this work, we have described a polyoxometalate (POM)-based inexpensive and easily synthesizable compound [Co(HO)][{K(HO)}VO]·2HO (), which exhibits electrocatalytic hydrogen evolution in its aqueous solution without its decomposition (or electrodeposition), acting as a rare homogeneous electrocatalyst. Even though the compound [Co(HO)][{K(HO)}VO]·2HO () (soluble in water) shows electrocatalytic hydrogen evolution reaction (HER) activity because of the Coulombic attraction, including H-bonding interactions, between the [Co(HO)] cationic species and [{K(HO)}VO]anionic species, the individual homogeneous solutions of [VO] (source: Na[VO]·18HO) and [Co(HO)] (source: CoCl·6HO) do not show any electrocatalytic HER activity. We have thus established that the synergy of [VO] with [Co(HO)] in crystal matrix as well as in the aqueous solution of makes the compound a stable and highly active electrocatalyst for homogeneous HER in an aqueous solution.

Ghost roads and the destruction of Asia-Pacific tropical forests.

Roads are expanding at the fastest pace in human history. This is the case especially in biodiversity-rich tropical nations, where roads can result in forest loss and fragmentation, wildfires, illicit land invasions and negative societal effects. Many roads are being constructed illegally or informally and do not appear on any existing road map; the toll of such 'ghost roads' on ecosystems is poorly understood.
