The" aim" of this study is to use the natural adsorbents which consist gum arabic as absorbents for plant products remove heavy metals from industrial wastewater and standard aqueous solutions with a prepackaged bed column (PBC) technique based on Box-Wilson design". The was modified into carbonated by oven maville at 300°C. influence were studied: pH value, contact time, removal efficiency est...

Anaesthesia Breathing System (formerly known as anaesthesia Breathing Apparatus or Anaesthesia Breathing Circuit) is an interface between the anaesthetic machine and the patient. They evolved over 160 years from the open systems used by Morton to the present day closed systems using carbon dioxide absorbents. The main purpose of these systems is to deliver the required oxygen and anaesthetic ga...

ALL modern volatile anesthetics produce carbon monoxide in strongly exothermic reactions with anhydrous carbon dioxide absorbents. Although desflurane produces the most carbon monoxide, the reaction with sevoflurane produces the most heat. Using real anesthesia machines, sevoflurane, and desiccated Baralyme® (Allied Healthcare Products, Inc., St. Louis, MO), peak absorbent canister temperatures...

In this line of research, Caram de Assis (2002) traces a study on the values of transmission for diverse glass types. The glasses that presented the biggest superficial temperatures, as the term-absorbents, act as “radiators”, decreasing the air temperature in the interior of the prototypes. However, the colorless glass showed that temperature increases less with the sun incidence but the insid...

An unusually large expansion upon solvent adsorption occurs without apparent bond breaking in the network of a series of isoreticular chromium(III) or iron(III) diarboxylates labeled MIL-88A to D [dicarbox = fumarate (88A); terephthalate (1,4-BDC) (88B); 2,6-naphthalenedicarboxylate (2,6-NDC) (88C); and 4-4'-biphenyldicarboxylate (4-4'-BPDC) (88D)]. This reversible "breathing" motion was analyz...

Purification of antilymphocyte antibody (ALA) from patients with systemic lupus erythematosus (SLE) was achieved by immunoabsorption and elution. Human tonsil cells or thymocytes were used as absorbents. Complement dependent microcytotoxicity tests showed that, in comparison to the parent sera, the eluate from tonsil cells was eight times, and that from thymocytes four times, more active. Antin...
