rock has been advantageously employed in hydraulic structures such as rockfill dams, gabion weirs and drain works. one rockfill dam applications can be flood control in wa-tershed management. the objectives of building rockfill detention dams are flow storage for a specific period and lowering of the outflow hydrograph. as this type of dam consists of coarse particles, seepage flow will deviate...

a new algorithm for classification of dmus to efficient and inefficient units in data envelopment analysis is presented. this algorithm uses the non-archimedean charnes-cooper-rhodes[1] (ccr) model. also, it applies an assurance value for the non-archimedean                          using only simple computations on inputs and outputs of dmus (see [18]). the convergence and efficiency of the ne...

basal cell carcinoma (bcc) is currently the most common cutaneous cancer found in humans. although it generally shows a relatively benign course (bccl), some cases show aggressive behavior (bcc2). until recently, traditional histologic diagnostic criteria have failed to discriminate unequivocally between bcc 1 and bcc2. in this study we selected 50 cases of bcc and categorized them into two gro...

we present a case of infantile intussusception treated successfully using hydrostatic reduction, highlighting the importance of non-surgical techniques as the first line of management for this entity. physicians should strive for mastery over such techniques by extensive training to prevent unwanted surgical procedures in such cases.

this study aims to investigate the capability of forming itraconazole containing niosomes with span 60 and brij 58 as non-ionic surfactants. lower cost and higher stability makes niosomes a more suitable choice in comparison with liposomes.the capability to form vesicles as an itraconazole delivery system and the influence of different factors such as type of surfactant and molar ratio of chole...

we present a sixth-order non-polynomial spline method for the solutions of two-point nonlinear boundary value problem u(4)+f(x,u)=0, u(a)=α1, u''(a)= α2, u(b)= β1,u''(b)= β2, in off step points. numerical method of sixth-order with end conditions of the order 6 is derived. the convergence analysis of the method has been discussed. numerical examples are presented to illustra...

abstract bronchoalveolar carcinoma presenting as non-resolving consolidation is an uncommon presentation. the typical presentation of bronchoalveolar carcinoma is asymptomatic (solitary nodule) and remains without symptoms even as disease disseminates. we report a case of bronchoalveolar carcinoma presenting as non-resolving consolidation in a young male with productive cough, exertional breath...

background: nicotiana tobacco contains large amounts of alkaloid nicotine. tobacco plant is used for smoking and causes many health problems since it is high in nicotine which is one of the widely-recognized toxic compounds with serious side effects for different body organs. reducing nicotine content of this plant is a way to reduce its health hazards in cigarette smokers. utilizing the new me...

background : non-alcoholic steatohepatitis (nash) is a common liver disease that, in the absence of treatment may progress to cirrhosis. there is a strong association of nash with insulin resistance; thus insulin sensitizer drugs have been used for this disease. the aim of this study was to compare the effect of pioglitazone with metformin on liver transaminases, the homa index, and adiponectin...

background one of the most important causes of mortality in developed and developing countries is coronary artery disease. coronary artery disease (cad) may develop by deposition of lipid, fibrous or calcified debris on the surface of the coronary artery lumen. fibrous plaque and calcified plaque may cause substantial stenosis of coronary arteries leading to ischemia of heart muscle while lipid...
