Scenario-based planning for reduction of emitted CO from the Pars Special Economic Energy Zone (PSEEZ) of Iran.

The Pars Special Economic Energy Zone (PSEEZ) is one of the largest gas reserves in the world. To reduce the CO emission from the area in line with the international climate commitments, two groups of scenario have been developed: the first is using the ecosystem services of mangrove forests, and the second is technology development for oil and gas industries. For the first scenario, the carbon sequestrated by the trees was calculated using the allometric equation, and the carbon of sediments was determined by using the Walkley-Black method.

Contamination, ecological risk and source identification of metals by multivariate analysis in surface sediments of the khouran Straits, the Persian Gulf.

Sediments are important hosts for metals and such should be incorporated in aquatic environment monitoring programs. In the present study, the concentrations of metals, multiple geochemical indices and guidelines along with multivariate statistical analysis were applied to identify the accumulation, sources and pollution levels of metals in the surface sediment. The mean metal concentrations in the sediments were ranked as follows: Fe > Cr > Ni > V > Zn > Cu > Pb > Cd.

Usefulness of red blood cell flags in diagnosing and differentiating thalassemia trait from iron-deficiency anemia.

Background: Thalassemia trait (THA) is an important differential diagnosis of iron deficiency anemia (IDA). The red cell distribution width (RDW) is usually elevated in IDA, but often is normal in THA.

Objective: This study was conducted to determine the usefulness of red cell flags in differentiating iron deficiency anemia and thalassemia trait.

[Pancreatic carcinoma].

Ductal adenocarcinomas represent over 90% of all pancreatic cancers. The high mortality has not changed over the last decades. Most patients are elderly and typically present with dull upper abdominal pain radiating to the back and often report reduced appetite, weight loss, and jaundice.
