carbon sequestration in soil and plant biomass is the most simple and economic way for co2 decrease that is important in environment improvement. this research was done in miankaleh region of behshahr in mazandaran for comparison of carbon sequestration in different plant types. firstly, plant types were determined and dominant species was identified in each type. number and size of plots was o...

in recent years, rangelands have been regarded as potential carbon sinks. one of the most widely suggested options to sequester more c in rangelands is the restoration of the degraded rangelands through grazing the exclusion. in present study, the effects of exclusion on the carbon sequestration of gomishan rangelands were investigated. three transects were established in a key area inside and ...

Congenital bronchopulmonary malformations are usually asymptomatic. Precise multimodality imaging plays an essential role in the identification of rare cardiothoracic entities, offering excellent imaging quality and the decisive diagnosis.

In addition to the lung tissue formed from the ventral pharyngeal diverticulum which represents the normal lung bud, pulmonary tissue may be formed from any part of the primitive foregut, and at birth is usually found lying in the left lower region of the pleural cavity; to this condition the name of lower accessory lung or extralobar sequestration is given. Such tissue should be distinguished ...

introduction climate change is one of the most important challenges in sustainable development, which has a negative impact on aquatic and terrestrial ecosystems. this will change rainfall patterns the power to increase hurricane and the risk of drought, flood and will strengthen pressure on water resources. researchers generally agree that the main cause of the increase in global temperature i...

Pulmonary sequestration is an uncommon congenital anomaly characterised by a mass of non-functional, dysplastic lung parenchyma that docs not communicate with the normal tracheobronchial tree. Such an anomaly commonly receives its blood supply from the systemic circulation. The sequestered pulmonary segment is considered to be intralobar if it is enclosed within the common pleura enveloping the...

Vision begins when light is captured by the outer segment organelle of photoreceptor cells in retina. Outer segments are modified cilia filled with hundreds flattened disk-shaped membranes. Disk membranes separated from surrounding plasma membrane, and each membrane type has unique protein components. The mechanisms underlying this sorting remain entirely unknown. In study, we investigated deli...
