Combining Air Purifier and Air Circulation Fan

The Puritans were a varied group of religious reformers who emerged within the Church of England during the middle of the sixteenth century.

Pureit offers a broad range of residential water-purification solutions, primarily in India.

The new PRO-Cell™ Upgrade Assembly magnifies the power of purification when added to any Field Controls UV-16. These models can be upgraded with the addition of a PCUV-16UA, boosting their UVC germicidal performance.

The GPS-iClean is the world’s first self-cleaning, no-maintenance air purification system that can reduce particles, control odors, kill pathogens, and even save energy by reducing ventilation air requirements.

Despite severe air pollution in Indian cities, particularly in Delhi-NCR, the market for air purifiers and anti-pollution personal care products remains small. Consumers perceive limited tangible benefits and sales spike only during peak pollution periods. While some growth occurs after Diwali, the overall market remains stagnant, with some companies exiting or scaling back operations.

Bharat Puri, MD of Pidilite Industries, discusses the company's revenue growth driven by volume growth and reduction in prices due to normalized raw material prices. Puri expects double-digit volume growth going forward and highlights the company's focus on investing in rural markets, which have shown no decline or softness. Pidilite Industries has added 30,000 new retail points to its rural network and sees rural markets as a driver of growth. Puri also mentions the improvement in international business and sustainable EBITDA margins at the higher range of 20-24%.

The board of Pidilite -- maker of Fevicol, Dr Fixit, Fevikwik and M-Seal -- at its meeting held on Thursday approved the appointment of Vats as Managing Director Designate, who is currently Deputy Managing Director of Pidilite Industries.

Initially thought of this in the context of a camping trip, but now also wondering about home safety purposes. What's the latest on ensuring that water is drinkable/potable and won't kill you?

•Iodine, sure, but what are the limitations? How much water per tablet can it purify?

•Boiling? To what temperature, for how long? Which types of microbe is it effective against?

•I know next to nothing about filters/osmosis.

•As far as I know, basically all of the above are for bacteria only. Which is good and all, but what if the water has chemical toxins instead of just biological? (Unlikely for a camping trip, I know, but somewhat more plausible when it comes to, say, well-water for a house.) Is there anything that works then? How to even tell if this is the case?

A minimal design, compact size, and true HEPA filter make Sharp's FPK50UW Air Purifier an affordable clean-home solution for travelers.

In their comment (1) on our publication (2), the authors make two points: (i) they raise concerns about the possible effect of residual NONOate in our study, and (ii) they promote nitrosylcobalamin (NOCbl) supplied by their own company. Both points lack merit for the following reasons. The authors make the astonishing claim that the spectra of nitric oxide (NO•) and cobalamins overlap. Unlike NO•, cobalamin absorbs in the visible region, permitting unequivocal spectral assignment of NOCbl as reported (3). We demonstrated that whereas NOCbl is highly unstable in solution, it is stabilized by the B12 trafficking protein CblC. So even if present, residual NONOate (which is unstable at neutral pH and is removed during the work-up (3)) could not account for the observed difference.The authors then misrepresent our synthetic method, claiming that anaerobic conditions were used to generate nitrocobalamin (NO2Cbl), which results in the transient formation of NOCbl. We synthesized NO2Cbl aerobically using nitrite as described (4); NOCbl is not an intermediate in this ligand exchange reaction. The aerobic instability of NOCbl has been rigorously described by inorganic chemists (3, 5) and raises obvious questions about its purported biological effects as exemplified by the authors' own 2003 JBC publication, which was later withdrawn.As to promoting NOCbl from their company, the authors refer to a synthetic route from a mixture of NO• gas and aquocobalamin. The authors' method (6) has been described as “dubious” by chemists (5). Whereas DEAE NONOate used in our method is widely known as an NO• donor,...

After a thorough read of this paper (1), we wish to clarify that the authors' anaerobic method of synthesis for the production of nitrocobalamin results in the transient formation of nitrosylcobalamin, an unstable intermediate upon exposure to air. We concur that the authors' method results in the production of nitrocobalamin based on the UV-visible data as shown. The authors' adapted anaerobic method consists of mixing hydroxocobalamin hydrochloride with diethylamine NONOate diethylammonium salt in aqueous solution. Of concern, the UV spectrum of nitric oxide overlaps that of all cobalamin species under anaerobic conditions, making any assignments of the binding of nitric oxide to hydroxocobalamin suspect (2). Additionally, the use of acetone to precipitate the authors' product causes precipitation of diethylamine NONOate, resulting in an impure product. As a result, its utility for drawing experimental conclusions is faulty.The product from the authors' anaerobic synthetic method has not been assessed for purity, and the synthetic method itself has not been validated using a stability-indicating method as required by the International Conference on Harmonization (ICH) (ICH Q2B, Validation of Analytical Procedures) methodology, which is a hallmark for analytical characterization. Our nitrosylcobalamin synthesis involves reacting nitric oxide gas with hydroxocobalamin acetate as a heterogeneous mixture in a non-electron-donating solvent followed by rotary evaporation. Our nitrosylcobalamin product is stable in air, releases nitric oxide gas in situ (3), and meets ICH stability guidelines (4). Additionally, our nitrosylcobalamin product demonstrates biological activity, which has not been observed for nitrocobalamin (3, 5).

Lipopolysaccharide (LPS) is a key player for innate immunity activation. It is therefore a prime target for sepsis treatment, as antibiotics are not sufficient to improve outcome during septic shock. An extracorporeal removal method by polymyxin (PMX) B direct hemoperfusion (PMX-DHP) is used in Japan, but recent trials failed to show a significant lowering of circulating LPS levels after PMX-DHP therapy. PMX-DHP has a direct effect on LPS molecules. However, LPS is not present in a free form in the circulation, as it is mainly carried by lipoproteins, including LDLs. Lipoproteins are critical for physiological LPS clearance, as LPSs are carried by LDLs to the liver for elimination. We hypothesized that LDL apheresis could be an alternate method for LPS removal. First, we demonstrated in vitro that LDL apheresis microbeads are almost as efficient as PMX beads to reduce LPS concentration in LPS-spiked human plasma, whereas it is not active in PBS. We found that PMX was also adsorbing lipoproteins, although less specifically. Then, we found that endogenous LPS of patients treated by LDL apheresis for familial hypercholesterolemia is also removed during their LDL apheresis sessions, with both electrostatic-based devices and filtration devices. Finally, LPS circulating in the plasma of septic shock and severe sepsis patients with gram-negative bacteremia was also removed in vitro by LDL adsorption. Overall, these results underline the importance of lipoproteins for LPS clearance, making them a prime target to study and treat endotoxemia-related conditions.

Oil and water can be separated efficiently by pumping the mixture through thin channels between two semipermeable membranes

Got an email about this. Looks cool. Is free. “I’ll write about that,” I thought. “I’ll write about that for Rock Paper Shotgun, a place that semi-regularly posts articles about cool and free games.” So here we are. If you’re waiting for the other shoe to drop, assuming the only reason I’d open an article in a superfluous and straightforward manner is because I’m about to deliver some sort of third sentence twist, you’re completely wrong! There’s no twist at all. I’m simply going to deliver some information about the game in a neutral tone. You can find VED: Purification, a free prologue demo to RPG VED, here.
