The field efficacy of a bait containing phloxine B, uranine and Provesta 621 protein was tested against Mediterranean fruit fly (Ceratitis capitata; Medfly) by aerial and ground spraying in about 84 ha of coffee fields in Kauai, Hawaii, USA. Concurrently, soil and crop samples were collected from the aerially sprayed field and its unsprayed control field for residue studies. Efficacy of the spr...

abstract: oxidation might be regarded as one of the most important reaction in oils and fats. prooxidants namely iron and copper intensify and catalyze the oxidation while the chelating agents might retard or delay this process. citric acid, phosphoric acid, some of phenolic compounds and phospholipids are considered as the compounds that chelate the prooxidant metals and through this mechanism...

Coffee, as one of the most consumed beverages, generates a wide variety waste materials that can be used biofuels and bio-products. Conventional pyrolysis in rural areas, improving circular bioeconomy these places. In this work, characterization slow specialty coffee residues, silverskin (CSS), spent (SC) were conducted at temperatures from 300 to 600 °C. Physico-chemical thermal analysis carri...

This paper analyses the effects of addition organic (coffee grounds) and inorganic (fly ash) residues to a clayey soil rich in quartz other silicates used as raw material brick production. To this end mineralogy, texture, durability physical mechanical properties solid bricks fired between 800 1100 °C were studied. The results show that firing temperature increased, phyllosilicate content decre...

the present research with an emphasis on coffee houses at qajar age has recognized motives and effect of social and political factors such as conditional event in formation of art traditions in coffee house so as to examine the communication function of coffee house painting at this space. coffee house at qajar age has been found as a place for people’s gathering which had communicative-cultura...

In this study, a new method for isolation of polyphenols (PP) from spent coffee grounds (SCG) and coffee silverskin (CS) is described. The method consisted of a mild hydrothermal pretreatment at 120°C, for 20 min, using a liquid-to-solid ratio of 20 mL/g. PP (determined as gallic acid equivalents, GAE) were the most abundant components in the extracts produced by this method, corresponding to 3...
