Portopulmonary hypertension (PPH) [1] is defined by the coexistence of portal and pulmonary hypertension. PPH is a serious complication of liver disease, present in 0.25 to 4% of all patients with cirrhosis. Once an absolute contraindication to liver transplantation, it is no longer, thanks to rapid advances in the treatment of this condition. [2]
Furthermore- passenger vehicles with an engine capacity greater than 4 cylinders are taxed again and as are those mass greater than 1500 kilogrammes (commonly four-wheel drives and SUV's). Transportation and logistics vehicles, trucks /lorries, buses , vans and utility pick-ups are taxed according to axle number, vehicle mass and maximum safe ...
This structure is typical for four-coordinate 18 e − complexes. [2] The corresponding complexes Ni(PPh 3) 4 and Pt(PPh 3) 4 are also well known. Such complexes reversibly dissociate PPh 3 ligands in solution, so reactions attributed to Pd(PPh 3) 4 often in fact arise from Pd(PPh 3) 3 or even Pd(PPh 3) 2. [3]
Pound per hour is a mass flow unit based on the international avoirdupois pound, which is used in both the British imperial and, being a former colony of Britain, the United States customary systems of measurement.
A Patent Cooperation Treaty/Patent Prosecution Highway (PCT/PPH) pilot program was also started on 29 January 2010 for a planned period of two years. This pilot program enables to "[fast-track] patent examination procedures for PCT applications that have received a positive written opinion of either the International Searching Authority or the International Preliminary Examining Authority, or ...
In the first step, PtCl 2 (PPh 3) 2 is generated. In the second step, this platinum(II) complex is reduced. The overall synthesis can be summarized as: K 2 [PtCl 4] + 2KOH + 4PPh 3 + C 2 H 5 OH → Pt(PPh 3) 4 + 4KCl + CH 3 CHO + 2H 2 O. Pt(PPh 3) 4 reacts with oxidants to give platinum(II) derivatives: Pt(PPh 3) 4 + Cl 2 → cis-PtCl 2 (PPh 3 ...
Several crystal structures containing PdCl 2 (PPh 3) 2 have been reported. In all of the structures, PdCl 2 (PPh 3) 2 adopts a square planar coordination geometry and the trans isomeric form. [5] [6] [7] [8]
Unreal Engine 4 (UE4) is the fourth version of Unreal Engine developed by Epic Games. UE4 began development in 2003 and was released in March 2014, with the first game using UE4 being released in April 2014.
