Light scattering methods for the physical analysis of synthetic and biological polymers neces8itates the use of scattering standards and absolute light scattering measurements. Standardization has not been employed when light scattering has been used to monitor immunochemical reactions using a kinetic or thermodynamic mode. The concentration of a specific protein present in a complex matrix suc...

This paper compares management of mastitis on organic dairy farms with that on conventional dairy farms. National standards for organic production vary by country. In the United States, usage of antimicrobials to treat dairy cattle results in permanent loss of organic status of the animal, effectively limiting treatment choices for animals experiencing bacterial diseases. There are no products ...

This review examines the scientific literature on the environmental concerns of arsenic additives in poultry litter. A number of questions were addressed on this issue. In summary, the review found: 1) Does arsenic from poultry feed amended with roxarsone end up in poultry litter? The arsenic found in poultry feed ends up in the poultry litter. Poultry litter from chickens receiving feed withou...

Students with sensory and physical disabilities are underrepresented in medical schools despite the availability of assistive technologies and accommodations. Unfortunately, many medical schools have adopted restrictive "organic" technical standards based on deficits rather than on the ability to do the work. Compelling ethical considerations of justice and beneficence should prompt change in t...

When communities of organic farmers began certifying ecologically friendly agriculture, they could never have guessed how prominent the certification model would become. Nearly four decades later, consumers can buy products not just from certified farms, but also certified forests, fisheries, and factories – with standards pertaining not only to the environment, but also to " social " condition...

The title compound, K(+).[(C(8)H(5)O(4))(2)H](-).2H(2)O or K(+).C(16)H(11)O(8)(-).2H(2)O, was prepared by slow evaporation of an aqueous solution of potassium hydrogen phthalate. The molecular complex consists of a potassium cation coordinated to a proton-bound hydrogen phthalate dimer and two water molecules. The potassium cation resides on a twofold axis in a distorted square-antiprism coordi...

A method for predicting volatility and polarity based on chromatographic information was developed and applied to the smog chamber ozonolysis of the sesquiterpene longifolene. The products were collected and analyzed using a GC×GC Thermal Desorption Aerosol Gas Chromatograph/Mass Spectrometer (2D-TAG) and a quadrupole Aerodyne Aerosol Mass Spectrometer (AMS). All the secondary organic aerosol (...

Soils are the third largest global reservoir of carbon and the largest terrestrial ecosystem sink or source of atmospheric CO2 depending on land-use and management. The French authorities ahead of COP21 proposed the ‘four per mil’ initiative aimed at offsetting most global agricultural CO2 emissions by increasing global soil organic carbon (SOC). Since, the Common Agricultural Policies (CAP) re...

Indoor air pollution is an increasing health concern, especially in enclosed environments such as underground subway stations because of increased global usage by urban populations. This study measured the indoor air quality of underground platforms at 10 metro stations of the Taipei Rapid Transit system (TRTS) in Taiwan, including humidity, temperature, carbon monoxide (CO), carbon dioxide (CO...
