A measurement technique is presented to increase the differentiation between single exhaust gas components using a pulsed-potential method. After applying a pulsed charging voltage (2.5 V) for a defined duration (100 ms) to a standard thimble-type zirconia-based potentiometric lambda probe, the self-discharge voltage of the sensor is recorded for a defined time duration (10 s) and repeated using a voltage with opposite sign. This pulse sequence with electrode polarizations of opposite signs is used permanently...
This research intended to evaluate thermal and light performance of transparent solar protections using measurements in full scale test cells, located in the city of Campinas, São Paulo, Brazil. Surface (window and shading device) and internal air temperatures were compared for six test cells. One of them was unprotected for reference purposes, another was obstructed with a metallic shading device and the other four had transparent glass horizontal and vertical shades installed. For light performance...

Several methods have been introduced for the treatment of submacular hemorrhages secondary to age-related macular degeneration. Small bleedings may be dislocated by intravitreal injection of SF6 gas, possibly combined with recombinant tissue plasminogen activator (rTPA). Larger hemorrhages can be treated by pars plana vitrectomy, subretinal injection of rTPA and gas tamponade. Large and particularly thick bleedings may require additional procedures such as subretinal lavage or the surgical removal of blood clots. Moreover, macular translocation surgery...

An Efficient Synthesis of 2-Aminofuran-3-carbonitriles via Cascade Stetter-γ-Ketonitrile Cyclization Reaction Catalyzed by N-Heterocyclic CarbenePeng Liu, Min Lei, Lei Ma & Lihong Hu
An efficient method for the synthesis of 4,5-disubstituted 2-aminofuran-3-carbonitriles via a cascade Stetter-γ-ketonitrile cyclization reaction of aromatic aldehydes with acylidenemalononitriles, catalyzed by N-heterocyclic carbenes, has been developed. This procedure provides the corresponding products in moderate to high yields under mild conditions.
A 30 years old female presented in Disha Eye Hospitals, Barrackpore, West Bengal, India with panuveitis with progressive tractional retinal detachment (TRD) involving macula in right eye. Her left eye was absolutely normal. An actively motile worm was detected at pars plana area at the time of vitreous base excision and removed in intact motile form. The large granulomatous tissue over the disc with thick epimacular membranes were removed. The retina was reattached and silicone...

The bell pepper experiment: introducing a novel self-sealing “screwcut” incision for sutureless transconjunctival vitrectomyL.-O. Hattenbach
Flattened sclerotomies are an essential step in ensuring postoperative wound stability in transconjunctival sutureless vitrectomy. However, in complex cases involving complete vitrectomy with shaving of the vitreous base, laser application and peeling of surface membranes, conventional angled incisions often leak at the end of the procedure. Here, we present a novel curved and twisted (screw-like=“screwcut“) self-sealing incision technique using a 23-gauge one-step microcannula array with sharp solid trocar blades. Based on a simple kitchen experiment,...
