Drying related plants

How often a container plant needs watering depends on the plant type, its size in relation to the container, the type of container (terra-cotta dries out more quickly than plastic), the site (a windy site increases the demand for water), the weather, and the season. Never let containers dry out—plants are much more prone to problems if they are short of water, and dry potting mix is difficult to rewet. In practice, most container plants need daily watering... 

Dry cleaning customers and employees of dry cleaning plants often complain about the chemical odor of perchloroethylene. More recently, with the recent process changes to reduce perc consumption and emission to the atmosphere, solvent turnover is minimized and complaints have arisen about a stale, stagnant and unpleasant odor that the customer relates to as clothes being cleaned in a dirty solvent (ISFA, 1999). Carbon dioxide dry cleaning clearly has an advantage here in that C02 is odorless. 

Design engineers can use Simprosys to design drying- and evaporation-related plants. Based on design requirements, they can quickly lay out the flowsheet and compute the heat/ mass/pressure balance of the whole plant and obtain the necessary process parameters such as the air flow rate to the dryer, the capacity and power requirements for the blower, and the heat duty of the heater. As part of the heat and mass balance calculation results, the thermal efficiency and specific...

The effects of dry stem crude extracts (DSCE) of Tinospora cordifolia and a related plant Tinospora malabarica have been shown to contain polyclonal B cell activators which are assumed to be polysaccharides. The DSCE were prepared by boiling the powdered stems in water followed by treatment with 10% trichloroacetic acid and filtration. The supernatant was further precipitated with acetone, and then fractionated on Sephadex G-200 and Sephacryl S-400 columns. The effects of these fractions were evaluated by culturing lymphocytes in vitro for 48 h in a 5% CO2 environment. Proliferation was estimated by pulsing 2x 10 cells with 1 iCi H-thymidine for 16 h and its incorporation measured by liquid scintillation counting. It was found that DSCE was mitogenic for lymphocytes from lymph node and spleen, while thymocytes, bone marrow cells and peripheral blood cells responded poorly [15].

Probabilistic safety assessment has had its greatest push in relation to the assessment ni risk associated with nuclear power plant operation as documented in the author s previous hook This new book, besides updating and reorganizing the nuclear portions of the previous text, entures into I he salety as.sessment of chemical facilities, another important industry dri ver of probabilistic s.ifety assessment methods and applications. 

Fig. 8. ABA accumulation in detached root tops (apical 20-30 mm) of Commelina as a function of root tip turgor. Root tips were excised from well-watered plants and dried in air at 23 °C in the dark until different percentages of fresh weight had been lost. This process took between 5 and 20 min. The samples were then maintained at the various water contents for 7 h prior to measurements of water relations and ABA content. Points are means s.e. of at least four measurements. Modified from Zhang Davies (1987).
