Cases of oil spillage and leakage in marine environments are increasing, generating a need to quickly assess the presence these contaminants seawater. This work aims estimate concentrations benzene, toluene, ethylbenzene xylenes (BTEX) dissolved seawater cases using experimental factorial planning. The study factors were °API oil/seawater contact time after spillage. models obtained able satisfactorily BTEX concentrations, with accuracy greater than 99.3% within ranges studied, R²...
Lichen planus (LP) is a relatively common mucocutaneous disease with autoimmune etiology. Considering its malignancy potential, it important to define the correct diagnosis, treatment, and clinical follow-up for patients LP so that not diagnosed late, thus hindering chances of curing disease. This study aims describe case oral squamous cell carcinoma, potentially originated from LP. The patient undergoing histopathological follow-up. A 64-year-old Caucasian male presented proliferative...
The objective of this study was to evaluate and obtain mathematical models, using the experimental design methodology, capable predicting contamination benzene, toluene, ethylbenzene xylenes (BTEX) in cases oil spillage at sea, acute toxicity soluble petroleum fraction (FSA). factorial planning developed describe concentration each compound according variables: °API, contact time oil/seawater after ambient temperature. models presented can be used quantitatively predict BTEX seawater with...
This study aimed to assess the toxicity of water soluble fraction (WSF) and correlate effects three oils their compositions, through bioassay with Mysidopsis juniae, analysis n-alkanes specific gravity. The PET01 PET02 were classified as light ºAPI 39.8 32.8 paraphynics more abundant n-alkane ranges from n-C10 n-C16, n-C9 n-C32. PET03 oil was heavy (°API 19.7), hydrocarbons in range n-C29 n-C33. It also possible evaluate concentrations metals petroleum, Ba (3.41-4.45 mg/kg), Fe (5.42-9.01 Zn...
