Carboxymethylcellulose ether media for cold-weather aerosol sampling.

Recovery efficiencies for Burkholderia thailandensis from various aerosol sampling media

Burkholderia thailandensis is used in the laboratory as a surrogate of the more virulent B. pseudomallei. Since inhalation is believed to be a natural route of infection for B. pseudomallei, many animal studies with B. pseudomallei and B. thailandensis utilize the inhalation route of exposure. The aim of the present study was to quantify the recovery efficiency of culturable B. thailandensis fr...

Effect of Antifreeze Admixtures on Cold Weather Concrete

Kashmir is located in a region where winter temperatures are very low. During the winter months, the temperature in Kashmir is often below 0⁰ C. Generally concrete placed in colder regions with the help of insulated forms as well as heaters to protect freshly mixed concrete against freezing. These practices try to incorporate unnecessary carbon and leads to an disagreeable carbon footprint. The...

Health Impacts of Cold Weather

Social Media for Cold Management

Social media has been increasingly used to manage emergencies (hot management), yet it is still unclear to which extent its use is truly beneficial to manage calm situations (cold management). Take socioeconomic deprivation of cities. Measuring it in an accurate and timely fashion has become a priority for governments around the world. Traditionally, deprivation indexes have been derived from c...

Interaction of cationic surfactants with carboxymethylcellulose in aqueous media.

We have examined the polymer-surfactant interaction in mixed solutions of the cationic surfactants, i.e., dodecyltrimethylammonium chloride, dodecyltrimethylammonium bromide, tetradecyltrimethylammonium bromide, hexadecyltrimethylammonium bromide, tetradecyltriphenylphosphonium bromide, and tetradecylpyridinium bromide and a semiflexible anionic polyelectrolyte carboxymethylcellulose in water a...
