the intraoperative care of pheochromocytomas can be difficult and lead to serious complications. we present a case of a 46 year-old female undergoing laparoscopic resection of pheochromocytoma, who was scheduled for surgery with phenoxybenzamine and amlodipin. under general anesthesia cardiovascular stability was achieved by peritumoral infiltration of lidocaine during resection.

study of the spatial variability of infiltration characteristics is essential to estimating infiltration parameters on a local scale. the objectives of the present study were to scale the parameters of a philip two-term model for infiltration and survey the variability of infiltration characteristics geostatistically using wastewater in the bajgah catchment. infiltration was measured at 30 poin...

The bearing capacity of strip footings on unsaturated soils is studied using slip line theory. The suction profiles considered are non-uniform with depth and correspond to vertical flow of water by infiltration or evaporation. The slip line theory assumes a plastic equilibrium state of a Mohr-Coulomb soil in which suction influences are included using the effective stress concept. This paper sh...

abstract- to study the effect of tree roots on increasing water infiltration in soil and also to determine and assess the coefficients of different infiltration models, some infiltration tests were performed in three tree plantation areas in badjgah, fars province with different soil textures (clay loam for pear plantation, sandy loam for grape plantation, loamy sand for pine trees). in each pl...

interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. to protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. as main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. ecologically, functional parameters such as stab...

bioretention or rain garden is a preferable low impact development (lid) approach due to its characteristics which reflect natural water cycle processes. however, this system is still little understood and quite complicated in terms of design and implementation due to many technical considerations. hence, this paper gives a review of the challenges and developments for the use of bioretention f...

Tumour growth and expansion are the result of proliferative activity and the capacity to eliminate cells by apoptosis and/or necrosis. The present study was aimed at comparing the apoptosis and proliferation intensity in cells of adenocarcinomas of the large intestine with the expression of metallothionein (MT), the grade of the tumour and the depth to which the tumour infiltrated the intestina...

study of soil quality indicators were considered as a useful method in the land use management. changing the land use affect soil hydrological processes such as water infiltration process. spatial variation of water infiltration in soil plays a very important role in hydrologic processes. variability of this process is affected by the inherent and non-inherent characters of the lands. in order ...
