Application of Response Surface Methodology for Analysing and Optimizing the Finned Solar Air Heater

作者： vinod kumar sharma ENEA Research Centre Trisaia AMB-TEIN-RIF Section Policoro.Italy

Potential use of hydrogen as future energy source is associated with a critical aspect of its production using sustainable technologies, and, in particular, the primary renewable energy sources. Amongst different technologies employed for hydrogen production from biomass, the gasification certainly represents one of the most potential and interesting options. Gasification plants of low-to-medium thermal capacity appears to be of considerable interest as the same not only helps to optimize transport infrastructure and distribution of hydrogen locally, but eliminates large structural and distribution carrier, generally required in case of conventional energy as well. It is in the above context that three gasification plants of thermal capacity 1.3 MWt, 10 MWt and 20 MWt have been analyzed. It is noted that the plants under investigation could produce up to 20, 152 and 304 kg/h of hydrogen, respectively, and are suitable for the realization of stand-alone systems for the refueling of vehicles. Process based on the biomass gasification with oxygen and vapor that produces a gas with hydrogen content of 20%-30% (volumetric, dry), has been considered, and produced gas has been subjected to its cleaning, enrichment and separation as well.

Upper limb length discrepancy is a rare occurrence. Humerus shortening may need specialized treatment to restore the functional and cosmetic status of upper limb. We report a case of humerus lengthening of 9 cm with a monorail external fixator and the result was observed during a 2-year follow-up. Humerus lengthening needs specialized focus as it is not only a cosmetic issue but also a functional demand. The monorail unilateral fixator is more functional and cosmetically acceptable, and thus becomes an effective treatment option.

Neurapraxia frequently occurs following traction injury to the nerve intraoperatively, leading to radial nerve palsy which usually recovers in 5-30 weeks. In our case, we had operated a distal one-third of humeral shaft fracture and fixed it with 4.5 mm limited contact dynamic compression plate. The distal neurovascular status of the limb was assessed postoperatively in the recovery room and was found to be intact and all the sensory-motor functions of the radial nerve were normal. On the second postoperative day, following the suction drain removal and dressing, patient developed immediate radial nerve palsy along with wrist drop. We reviewed the literature and found no obvious cause for the nerve palsy and concluded that it was due to traction injury to the radial nerve while removing the suction drain in negative pressure.

Objective:To measure the effect of doxycycline on inflammatory marker[IL-6,TNF-α,ferritin and C reactive protein(CRP)]levels in patients with dengue ***:A single-centre,open-label,parallel-group randomized controlled trial was done in PGIMER Chandigarh from June 2021 to October *** were randomized using a simple randomization process into two groups:the doxycycline treatment group(n=35)and the control group(n=34).Patients in the treatment group were given oral doxycycline 100 mg twice daily for five days along with standard treatment,whereas patients in the control group received only standard *** objective was to measure the effect of doxycycline on inflammatory markers in dengue ***:On comparative analysis at day 5,there was a statistically significant reduction in the median values of ferritin and CRP in cases compared to the control group(ferritin:P=0.006 and CRP:P=0.006).No significant reduction was noted in the levels of IL-6 and TNF-α.Conclusions:Doxycycline treatment led to a reduction of inflammatory markers in dengue infection.
