because of the everyday use of power generators in iraq, which exist in residential neighborhoods, it is necessary to study the impact on soils and plants surrounding areas of those generators. lead is one the most heavy metals released especially, as a result of the combustion of diesel fuel during operation of the powered generators. however, a study was conducted to investigate the lead conc...

background and purpose: generated dye wastewater by the textile industry is usually toxic, non-biodegradable and resistant in the environment. eggshell is one of the inexpensive material and for the reason the vesicular structures can be used as a proper adsorbent for pollutants removal. the aim of this study is to investigate the efficiency of eggshell for removal of acid orange 2 dye from aqu...

introduction: the aim of this in vitro study was to evaluate the dissolving efficacy of eucalyptol and orange oil solvents associated with passive ultrasonic activation (pua) in zinc oxide-eugenol (zoe) based and epoxy resin-based root canal sealers. methods and materials: seventy samples of each sealer were prepared and then randomized according to the solvent and the time of the ultrasonic ac...

this study aimed to assess the effect of chloroform, eucalyptol and orange oil solvents on the microhardness of human root dentin.sixty-eight single-rooted single-canal extracted human premolar teeth were used. tooth crowns were separated from the roots at the cementoenamel junction (cej). roots were buccolingually sectioned into mesial and distal halves. specimens were randomly divided into 5 ...

The biology of the citrus psyllid Diaphorina citri Kuwayama was studied at 258C on four commonly grown citrus and related plants [rough lemon, Citrus jambhiri Lush; sour orange, C. aurantiumL.; grapefruit,C.paradisiMacfadyen; andorange jessamine,Murrayapaniculata(L.) Jack] in the laboratory. The biological characteristics of each life stage are described. The average egg incubation periods on o...

OBJECTIVE The aim of this study was to evaluate the erosive/abrasive enamel wear after contact with orange juices modified with different dietary supplements. METHODS A total of 96 bovine enamel samples were prepared and allocated to eight groups (1-8; n = 12). Samples were eroded (120 s) in 200 ml of the following eight solutions: 1: water (control), 2: orange juice, 3: water + calcium effer...

Accelerated bleaching and photobleaching of diluted solutions of Methyl Orange and other dyes occur only when Co2+-ions are present in solution mediating oxone (2KHSO5·KHSO4·K2SO4) decomposition. The bleaching of Methyl Orange, Orange II and Methylene Blue dyes in dilute solutions (0.01 mM) proceeds within a few minutes and occurs at biocompatible pH leading to a decrease in the toxicity of the...

Dichlorvos (dimethyl 2,2-dichlorovinyl phosphate) inhibits the biosynthesis of aflatoxin by Aspergillus parasiticus. Cultures treated with dichlorvos excrete an orange pigment which can be converted into aflatoxin B(1) by the untreated mycelia. The orange pigment was partially identified as an acetyl derivative of versiconol-type compound. In the presence of dichlorvos, sterigmatocystin is conv...
