Disease and Development: A Reply to Bloom, Canning, and Fink
Beginning in the 1940s, a wave of health innovations and more effective international public health measures led to a rapid and large improvement in health; for example, in some relatively poor countries, life expectancy at birth quickly rose from around 40 years to over 60 years. In Acemoglu and Johnson ð2006, 2007Þ, we constructed an instrument for these changes in life expectancy: “predicted...
متن کاملHeat penetration and thermocouple location in home canning
We processed applesauce, tomato juice, and cranberries in pint jars in a boiling water canner to test thermal processing theories against home canning of high-acid foods. For each product, thermocouples were placed at various heights in the jar. Values for f h (heating), f cl (cooling), and F 82.2°C (lethality) were determined for each thermocouple location, and did not depend substantially on ...
متن کاملGreen recovery of pectic polysaccharides from citrus canning processing water
Canned citrus segments are popularly consumed worldwide with a large global market. However, the production needs chemical treatment to remove segments membranes, producing a large amount of acidic and basic effluents with very high chemical oxygen demand (COD), causing serious environmental problems. This research is focused on the plant scale recovery of pectic polysaccharides from the above ...
متن کاملMapping seagrass in the Swan-Canning Estuary using sidescan sonar
Seagrass distribution and other measures of seagrass condition have been used as broad scale biological indicators of marine and estuarine health. To date the distribution of seagrass in the Swan-Canning Estuary has been assessed based on aerial photographs, which is ineffective in deep, turbid waters. Sidescan sonar systems (SSS) provide acceptable results in a much wider range of environmenta...
متن کاملFull recovery of value-added compounds from citrus canning processing water
The citrus canning industry generates large quantities of processing water rich in phytochemical compounds during the sequential acidic and alkaline removal of the citrus segments membrane. However, this processing water was discharged as an effluent causing high chemical oxygen demand (COD). In the present research, a pilot scale process was designed to simultaneously recover pectin and a low ...
