With the extensive use of self-consolidating concrete (SCC) worldwide, it is important to ensure that such concrete can secure uniform in-situ mechanical properties that are similar to those obtained with properly consolidated concrete of conventional fluidity. Ensuring proper stability of SCC is essential to enhance the uniformity of in-situ mechanical properties, including bond to embedded re...

we have analyzed paraffin sections from 55 patients with histologically confirmed hodgkin’s disease (hd) for the presence of epstein-barr virus (ebv) markers using in situ hybridization to detect the ebv-encoded rnas (ebers) and immunohistochemistry to identify latent membrane protein-1 (lmp1) expression. tissue specimens from 55 cases of hodgkin’s disease included 22-mixed cellularity (mc), 27...

background:breast cancer remains the most common and second lethal cancer in females. her-2/neu is one of the most important amplified oncogene in breast cancer. the amplification of her-2 is correlated with decreased survival, metastasis, and early recurrence.  the amplification of her-2/neu gene and synthesis of the protein are reported in 10%-34% of breast cancer cases associated with tumor ...

background the incidence rate of gastric cancer in western countries has shown a remarkable decline in the recent years while it is still the most common cancer among males in iran. the proto-oncogene myc, located at 8q24.1, regulates almost 15% of human genes and is activated in 20% of all tumors. the amplification of myc and overexpression of its protein product are observed in 15 - 30% of ga...

In order to increasing of hydroxy functionality of HTPB an in-situ nitroxide mediated polymerization (NMP) of 1,3-butadiene was carried out in presence of TEPA as a polyfunctional nitroxide precursor. The multi-modal molar mass distribution of the product was elucidated by reductive hydrolyzation of the oligomeric product. The new polyfunctional hydroxyl-terminated polybutadiene (PFHTPB) was c...

In studying of the in situ gravitational concentration process part feature for placer, the technological ability to transform the in situ massif placer structure is evident. The two main processes involved in altering the massif in situ have been examined and outlined in detail. The in situ disintegration of massif material results in a new massif gravitational stratification structure. Regula...

Graphene/Cu composites were fabricated through a graphene in-situ grown approach, which involved ball-milling of Cu powders with PMMA as solid carbon source, in-situ growth of graphene on flaky Cu powders and vacuum hot-press sintering. SEM and TEM characterization results indicated that graphene in-situ grown on Cu powders guaranteed a homogeneous dispersion and a good combination between grap...
