Respiratory Health Hazards in Agriculture

Respiratory diseases associated with agriculture were one of the first-recognized occupational hazards. As early as 1555, Olaus Magnus warned about the dangers of inhaling grain dusts, and the risk was again noted in 1700 by Ramazzini in his seminal work De Morbis Artificum ().

Solution Combustion Synthesis of Nanoscale Materials

The elemental crystalline cell contains atoms that function as a fuel (H, C), as well as atoms of oxidizer (e.g., O), which are separated by angstrom-scale distances. The metal hydrazinecarboxylate hydrates decompose in air at relatively low temperature (125–250 C), yielding ultrafine solid oxides of the corresponding metal and a large amount of gaseous products.

Evaluation of compost, vegetable and food waste as

2018/10/11Regular usage of NaOH/NaClO disinfectants results in high sodium salt and alkalinity of poultry manure. This study compared three amendments: vegetable waste (V), food waste (F) and mature compost (C) for their ability to improve the composting of NaOH/NaClO-contaminated poultry manure. C compost resulted in the highest compost temperatures (p0.001) and greatest reduction in

Two levels of Ti addition were examined, i.e., 0.05#x0025; and 0.15#x0025;. Thermal analysis was the only technique used to obtain castings, from which samples were then sectioned for metallographic examination. Based on the results obtained,

2014/10/1Elemental analysis was achieved using a vario EL II analyzer. Fourier transformed infrared (FTIR) spectrum was collected on a Nicolet 6700 FTIR spectrometer using KBr pressed disks. 1 H NMR and 13 C NMR spectra were performed with a Bruker Avance III 600 MHz spectrometer by dissolving 20 mg of the S-C-dots in 700 μL of D 2 O. Zeta potential was measured on a nano Z zeta potential analyzer.
