Forty-five feedstuffs (464 total samples) were obtained from suppliers as well as swine feed and pet foo...
Study of physical and chemical characteristics of dust storms in Iran is necessary. In this regard, 10 samples from Khozestan dust storms in 1387 and 1388 were collected for XRD and SEM studies. XRD result show that mineralogical composition of these dust particles can be divided into three groups: (1) Carbonate group (calcite mineral), (2) Silicate group (quartz mineral) and (3) Clay group (Ka...
