understanding the performance and role of each formation in a petroleum play is crucial for the efficient and precise exploration and exploitation of trapped hydrocarbons in a sedimentary basin. the lorestan basin is one of the most important hydrocarbon basins of iran, and it includes various oil-prone potential source rocks and reservoir rocks. previous geochemical studies of the basin were n...

A 63-year-old woman was hospitalized after 2 episodes of mucoid, maroon-colored stools. She denied any prior or current episodes of abdominal pain, vomiting, fever, or recent travel. She was hemodynamically stable without significant drop in hematocrit. Colonoscopy revealed a 5-cm polypoid mass in the ascending colon with ulceration and fat eroding through the mucosa (Figure 1). The colonicsegm...

BACKGROUND A retrospective study was performed to assess the causes, diagnostic methods for, and clinical features of, jejunoileal hemorrhage in Shandong province, China and to derive recommendations for management of this condition from these data. METHODS We performed a retrospective systematic collection of data from between January 1999 and December 2008 in seven cities in Shandong provin...

Abstract We present high-resolution dayside thermal emission observations of the exoplanet KELT-20b/MASCARA-2b using MAROON-X spectrograph. Applying cross-correlation method with both empirical and theoretical masks a retrieval analysis, we confirm previous detections Fe i lines detect Ni for first time in planet (at 4.7 σ confidence). do not see evidence additional species data, including nota...

Fabrication of a test strip for detection of benzoic acid was successfully implemented by immobilizing tyrosinase, phenol and 3-methyl-2-benzothiazolinone hydrazone (MBTH) onto filter paper using polystyrene as polymeric support. The sensing scheme was based on the decreasing intensity of the maroon colour of the test strip when introduced into benzoic acid solution. The test strip was characte...

Hematochezia is the passage of bright red blood or maroon colored blood, with or without clots, per rectum. Most often hematochezia is low grade and self limited and does not require hospitalization or urgent intervention. Such patients can be managed in an outpatient setting. A smaller group of patients experience severe hematochezia and require hospitalization because of the volume of blood l...

background : the aim of this study was to evaluate the performance of water ozonation on disinfection by-product formation. methods : experiments were carried out on samples taken from tajan river, mazandaran province, iran. samples of the pre-filtered raw water and from the 3.5-l water tank reservoir (wt) were analyzed for uv-254 absorbance, dissolved organic carbon (doc), hs and non-hs, chlor...
