THE EFFECTS OF POROSITY AND SATURATION ON ELECTRICAL RESISTIVITY AND STRENGTH OF SOIL FOR SAND SIZE PARTICLES

Geophysical methods had become increasingly practiced in engineering site characterization as being quicker, more economical, and allow more data to be taken than the present method. Electrical resistivity was conducted by supply generated electric current to the soil and the resulting potential differences are measured. This research presents the effects of porosity and saturation on electrical resistivity and strength of soil for sand size particles. It was a study about the effects of porosity and saturation on electrical resistivity of sand size particles ranges between 0.029mm to 2.00mm. Soil sample was mixed with distilled water and left for 24 hours. The compaction test conducted with different blows in each of moisture content ranged 25% to 40%. Electrical resistivity test as well as pocket penetrometer test had been done right after the compaction test to analyzed and understand the effects of porosity, saturation and cohesion on electrical resistivity. Results show that the effects of porosity on electrical resistivity of sand size particles is when the porosity is high, it means that there is less water in the pore and the resistivity will get higher because water is the good in conductivity. When moisture content is higher, the resistivity will get lower. From test, it shows that there is no specific trend for resistivity against saturation but past studies shows that the lower the saturation, the higher the resistivity. For the cohesion, the lower the moisture content, the higher the resistivity, the higher the cohesion. This showed that the higher the compaction, the stronger the soil will be. The results of this research can be used for geotechnical site investigation by using electrical resistivity

The role of content knowledge in the use of reading strategies

Many studies have been carried out to determine the causes of difficulty in comprehending texts. Among those frequently cited as factors that either inhibit or enhance text comprehension are the reader's content knowledge, the medium oflanguage used to convey the content, the reader's Ll reading ability and the reader's level of education. When reading subject-specific texts which are heavily-laden with facts, content knowledge is undoubtedly one of the biggest factors that determine a reader's success in reading comprehension. Readers would face great difficulty in comprehending such texts if they do not possess a sufficient level of content knowledge. The level of content knowledge one possesses influences the quality of reading as it activates the quality of questions raised by the reader (Scardamalia and Bereiter, 1991)

Armus dual roles in autophagy and E-cadherin degradation: distinct partners, regulation and implications for cancer patients

Cancer is one of the leading causes of mortality worldwide. Invasion, metastasis and apoptotic evasion are cancer hallmarks. Tumour cell metastasis requires loss of E-cadherin cell-cell adhesion receptor. Apoptotic evasion can be mediated by up-regulation of autophagy, which maintains cellular energy during metabolic stress in cancer cells. Armus is a TBC/RabGAP protein that regulates both E-cadherin degradation and autophagy by controlling lysosome fusion with late vesicular compartments or autophagosomes. Understanding Armus function in these degradative processes during tumourigenesis may lead to combinatorial inhibition of oncogenic pathways and novel therapeutic targets. Here I address: (i) whether Armus participates in E-cadherin deregulation downstream of oncogenes, (ii) potential mechanisms through which Armus can switch between its function at junctions and autophagosomes and (iii) potential strategies to inhibit Armus intracellular localisation. I found that Armus is involved in Src and H-Ras disruption of E-cadherin junctions in keratinocytes. Armus binds to α-catenin at junctions, while at autophagosomes Armus interacts with autophagy marker, LC3. Incubation with Armus peptides containing LC3-interacting motifs partially blocks Armus function in autophagy. Mutation of the specific residues mediating α-catenin association reduces Armus localisation at cell-cell contacts. The close juxtaposition of LC3 and α-catenin binding at PH domain at Armus N-terminus may suggest additional roles. Armus N-terminus and RabGAP domain interact directly, and residue K480 is critical for binding. This intramolecular interaction may form a closed conformation, and Armus activation may require the release of this auto-inhibition. It is tempting to suggest that protein interactions at the PH domain such as LC3 and α-catenin may modulate Armus auto-inhibition. Alternatively, the phosphoinositide repertoire interacting with the PH domain may contribute to Armus intracellular distribution and activation. Further insights into Armus activation may provide greater understanding of its function in distinct cellular events with implications for tumourigenesis.Open Acces
