In the Focus: Inmatec Gasetechnologie Gmbh & Co.Kg Medical oxygen plays an important role in coping with the corona crisis. It is used worldwide to treat Covid patients and is now also used to manufacture life-saving vaccines. With self-sufficient O2 generation, hospitals and pharmaceutical manufacturers secure the supply and reduce their costs at the same time. Medical oxygen has been used ...
As a result, we observed both the positive and negative impacts on the ambient air quality. The wildfire occurrences severely deteriorated the air quality. In contrast, country-wide complete and partial lockdowns accounted for cleaner air in some regions. The lockdown provided a clean window to air and ...
The big plus of Inmatec products: The medical oxygen does not have to be delivered, but is taken from the ambient air and filtered. The first deliveries were made to the states of Kashmir and Jammu. ...
With winter just around the corner, the management of ventilation inside buildings is becoming increasingly important. We’ve known for some time that there is a risk of the virus spreading via airborne transmission and now the cooler weather has arrived forcing windows and natural ventilation sources to close, it is something that workplaces need to address. Over recent months, the role ...
Providing indoor air quality to meet the safety of the occupants is a daunting task—at best. Ventilation –that is—supplying both outside air and re-circulated are at a rate that the majority of occupants of a classroom, gymnasium, office, or sports arena, would find safe and comfortable has been undertaken by such professional groups as ASHRAE (American Society of Heating, ...
15 weeks into the COVID-19 pandemic, scientists know a lot more about how the disease is transmitted. The highest risk for public health is from crowded indoor spaces with poor ventilation, and especially with prolonged face-to-face interactions. In close proximity, people speaking, coughing, singing, or simply breathing can produce respiratory droplets containing the COVID-19 (SARS-CoV-2) ...
The advantage: the generators filter the oxygen from the air. Herrsching - The corona pandemic is currently keeping the whole world in suspense: In extreme cases, the Covid-19 virus infection can lead to severe pneumonia, so that patients in the intensive care unit have to be artificially ventilated by a lung machine. ...
When we think about air pollution, we think about black smoke coming out of stacks in a grey, industrial area in a developing country. And that is also the case. But not only. Air pollution comes in different forms and not always visible to the human eye. ...

In the summer of 1974, the Hollies had a Top 10 hit when they sang, “All I need is the air that I breathe and to love you.” They were smart enough to recognize the importance, even in a midst of a heated romantic relationship, of breathing clean, fresh air. Dentists should take note. According to Department of Labor statistics published in Business Insider, the dental profession ...
Asthma rates have been on the rise for some time - in 2009 nearly 1 in 12 Americans were diagnosed with the long-term inflammatory disease that restricts airways and makes it difficult to breathe. Other symptoms include coughing, wheezing and chest tightness, and these often get worse when the patient is also fighting a common cold or flu. Asthma affects people of all ages, but especially ...
It's probably telling that the word ‘fracking’ sounds just shy of a curse word. Researchers at the Johns Hopkins Bloomberg School of Public Health have found that people who live near active, unconventional natural gas wells operated by the fracking industry were significantly more likely to suffer from asthma attacks. It’s the latest in a string of studies that has linked the ...
A key improvement has been the addition of data logging capability which facilitates testing of medical air plant and oxygen concentrators. The instrument has a fast re-charge with excellent battery life. ...
If you think it’s hard to get HVAC money for schools and similar public buildings, there is a harder nut to crack: correctional facilities. It can be even more difficult to get additional funds appropriated to improve conditions in buildings where people are incarcerated. Compounding the problem, many correctional facility employees are in close proximity with the inmate community daily. ...

As are the other inert gases (Helium, Neon, Argon and Krypton), Xenon is found in and makes up part of the air. Krypton and Xenon, however, are found in significantly smaller concentrations than the other gases. Inert gases are usually obtained on a largescale in air separation plants as a by-product during the fractional distillation of liquid ...
By design, this study coincided with the 1994 Nashville/Middle Tennessee Ozone Study conducted by the Southern Oxidants Study, which provided enhanced continuous ambient O3 monitoring across the Nashville area. Passive sampling estimated weekly average outdoor O3 concentrations from 0.011 to 0.030 ppm in the urban Inglewood community and from 0.015 to 0.042 ppm in suburban ...
