A phosphorus-fluorine containing compound tetraphenylphosphine hexafluorophosphate (Ph4PPF6) was synthesized by one-step method and characterized FTIR, NMR, SEM, EDX. Epoxy resin (EP) cured with an aliphatic hardener Ph4PPF6 as a multifunctional additive were fabricated. The combined effects of melamine (MEL) copper hydroxystannate (CuHS) on the fire safety, thermal stability, smoke toxicity di...

Energy is the key mover for any country’s development. In today’s era, demand energy rapidly increasing and cost of power also due to lack fossil fuels (coal, gas, oil). To overcome worst crises non-renewable resources, present solution move towards renewable energy. Sindh a province Pakistan that has immense capability prospect neat green production. The major locations resources are found in ...

The leverage of large volumes web videos paired with the query (short phrase for searching video) or surrounding text (long textual description, e.g., video title) offers an economic and extensible alternative to supervised representation learning. Nevertheless, modeling such weakly visual-textual connection is not trivial due polysemy (i.e., many possible meanings a query) isomorphism same syn...

The aim of the study was to define relationship between flexibility, explosive strength and speed of running. Fifty-six young (aged 15-19) czech soccer players participated this research. Data about flexibility (sit and reach test – HF), explosive strength (countermovement vertical jump – VJ) and speed of running (10 meters sprint – 10m) were collected. For analyse the data software Statistica ...

The effects of diphenylhydantoin (DPH) on in vitro rabbit retinas were studied. DPH, 10M., inhibited the appearance of the P II (b-wave) and the P HI component of the electroretinogram (ERG), while 10-* M. DPH increased the P II and P III amplitudes. DPH of 10M. or lower concentrations did not affect the ERG. The DPH response was the same whether perfusion was from the receptor cell side or gan...

We use a homogeneous sample of ∼ 300, 0.3 < ∼ z < ∼ 3, radio-loud quasars drawn from the FIRST and 2dF QSO surveys to investigate a possible dependence of radio activity on black-hole mass. By analyzing composite spectra for the populations of radio-quiet and radio-loud QSOs – chosen to have the same redshift and luminosity distribution – we find with high statistical significance that radio-lo...

In this research, the high-energy planetary mill was employed to produce nanocrystalline Ti-50Al(γ)(at%) powders. Initial powders were mechanically alloyed in 99.9999% and 90% purities of Argon and also Air atmosphere with alloying times up to 50h. The effect of impurity of Argon atmosphere on the microstructure and the rate of phase transformation of Ti-50Al were investigated during mechanical...
