The cost associated with the application of large volume of cement and synthetic admixtures was one of the major drawbacks of Self Compacting Concrete (SCC), which can be reduced by the use of supplementary cementitious materials (SCM). When the demand of cement reduces, the release of carbon dioxide (CO2) from cement industries will come down, which has a positive impact on global w...

Background & Aim: Despite valuable medicinal properties of safflower, breeding new varieties and development of the crop culture area has been limited due to the lack of genetic variation for some crucial characteristics as resistance to diseases and pests like safflower fly. In this study, populations of wild safflower, C. oxyacanthus were collected from western, central and ...

leishmaniasis has long been known as a significant public health challenge in many parts of iran. phlebotomus pa­patasi and p. sergent i are the vectors of zoonotic cutaneous leishmaniasis and anthroponotic cutaneous leish­maniasis respectively, and 5 species of sand flies including p. kandelakii , p. neglectus , p. perfiliewi , p. keshishiani and p. alexandri are considered as probable vectors...

Today coal is among the most important energy sources. In order to meet the world's energy demands, low-calorie lignite with a high ash content is generally used in the large capacity coal-fired thermal power plants. As a result of coal firing, wastes such as fly ash, slag, and flue gas are also produced. Subsequently, toxic trace elements within coal are transferred to wastes such as slag, fl...

Attack rates, progeny production, sex ratios, and host utilization efficiency of Muscidifurax raptorellus (Kogan and Legner) (Hymenoptera: Pteromalidae), Tachinaephagus zealandicus Ashmead (Hymenoptera: Encyrtidae), and Trichopria nigra (Nees) (Hymenoptera: Diapriidae) were evaluated in laboratory bioassays with five dipteran hosts: house fly (Musca domestica L.), stable fly (Stomoxys calcitran...

zeolite was synthesized from coal tailings and coal fly ash sampled from zarand coal washing plant, iran, using h2o2–promoted hydrothermal treatment. samples consisted mainly of sio2 and al2o3 which are the main components for the zeolite synthesis. to perform the experiments, appropriate amount of the starting materials were mixed with 240 ml volume of 30% h2o2 at room temperature with continu...
