Corrosion Behavior of Mild Steel in Various Environments Including CO2, H2S, and Their Combinations

open access: yesMetals
This paper investigates the corrosion behavior of mild steel in simulated oilfield wastewater under CO2, H2S, and their mixture. Using the electrical resistance method, the corrosion rates were monitored, and the influence of corrosion product films on ...

Synthesis and Characterization of Cellulose Acetate from TCF Oil Palm Empty Fruit Bunch Pulp

open access: yesBioResources, 2014
Cellulose acetate (CA) was successfully synthesized by the acetylation of TCF cellulose pulp from oil palm empty fruit bunches (OPEFB) at room temperature, using acetic anhydride as the acetylating agent and acetic acid as the solvent in the presence of ...

Thermal noise in half infinite mirrors with non-uniform loss: a slab of excess loss in a half infinite mirror [PDF]

open access: yes, 2001
We calculate the thermal noise in half-infinite mirrors containing a layer of arbitrary thickness and depth made of excessively lossy material but with the same elastic material properties as the substrate.

Chimeric diphtheria toxin–CCL8 cytotoxic peptide for breast cancer management

open access: yesMolecular Oncology, EarlyView.
DTCCL8 is a recombinant fusion toxin that targets cancer cells expressing chemokine receptors. By combining diphtheria toxin with CCL8, DTCCL8 binds to multiple receptors on tumor cells and induces selective cytotoxicity. This strategy enables receptor‐mediated targeting of cancer and may support the development of chemokine‐guided therapeutics ...

Burnishing technique improves lubrication of threaded fasteners [PDF]

open access: yes, 1965
Burnishing a molydisulfide coating into the thread surfaces of fasteners eliminates the need for binders and vehicles which ensure coverage and retention of the lubricant during fastening.

ITGAV and SMAD4 influence the progression and clinical outcome of pancreatic ductal adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
In SMAD4‐positive pancreatic ductal adenocarcinoma (PDAC), integrin subunit alpha V (ITGAV) activates latent TGF‐β, which binds to the TGF‐β receptor and phosphorylates SMAD2/3. The activated SMAD2/3 forms a complex with SMAD4, and together they translocate to the nucleus, modulating gene expression to promote proliferation, migration, and invasion. In

Exploring the role of cyclin D1 in the pathogenesis of multiple myeloma beyond cell cycle regulation

open access: yesMolecular Oncology, EarlyView.
Cyclin D1 overexpression altered the cell adhesion pathway, while cyclin D2 upregulation had less impact on pathway enrichment analysis. Multiple myeloma (MM) patients with cyclin D1 overexpression showed reduced CD56 expression and increased circulating tumor cells (CTC) levels, suggesting that cyclin D1 may contribute to MM cell dissemination ...

NASA thermal barrier coatings: Summary and update [PDF]

open access: yes
A durable, two-layer, plasma-sprayed coating consisting of a ceramic layer over a metallic layer was developed that has the potential of insulating hot engine parts and thereby reducing metal temperatures and coolant flow requirements and/or permitting ...
