Opis:
Titanium usage for aerospace growing day by day as application of titanium and its alloys covers wide range. Most of the aerospace components made up of wall structure involves lot of pocket slot milling since those components are monolithic components, eliminating need to manufacture multiple pieces for assembly into one final part. The increasing complexity of titanium parts used in aviation industry, increasing demand for productive manufacturing methods like trochoidal milling. This paper aims at evaluating its potential in slot milling for Ti6Al4V component by conducting experiments on 5-axis CNC machine. This study focuses on Productivity, Quality and Machine Tool Dynamics.

Opis:
Recent experimental and theoretical investigations have resulted in a shift in our understanding of the ν=1 quantum Hall state. There now exists a wealth of evidence that the excitation gap and the resulting quasiparticle spectrum at ν=1 are due predominately to the ferromagnetic many-body exchange interaction. A great variety of experimentally observed correlations at ν= 1 cannot be incorporated into a perturbative expansion around the single-particle model, a scheme long thought to describe the integral quantum Hall effect at filling factor 1. Theorists now refer to the ν=1 state as the quantum Hall ferromagnet. In this paper we review recent theoretical and experimental progress and detail our own optical investigations of the ν= 1 quantum Hall regime. The technique of magneto-absorption spectroscopy has proven to be powerful a probe of the occupancy of the lowest Landau level in the regime of 0.7<ν<1.3 about the spin gap. Additionally, we have performed simultaneous measurements of the absorption, photoluminescence and photoluminescence excitation spectra of the ν=1 state in order to elucidate the role of excitonic and relaxation effects in optical spectroscopy in the quantum Hall regime.

Opis:
Since the first confirmed case in Wuhan, China on December 31, 2019, the novel coronavirus (SARS-CoV-2) has spread quickly, infecting 165 million people as of May 2021. Since this first detection, research has indicated that people contracting the virus may suffer neurological and mental disorders and deficits, in addition to the respiratory and other organ challenges caused by COVID-19. Specifically, early evidence suggests that COVID-19 has both mild (e.g., loss of smell (anosmia), loss of taste (ageusia), latent blinks (heterophila), headaches, dizziness, confusion) and more severe outcomes (e.g., cognitive impairments, seizures, delirium, psychosis, strokes). Longer-term neurological challenges or damage may also occur. This knowledge should inform clinical guidelines, assessment, and public health planning while more systematic research using biological, clinical, and longitudinal methods provides further insights.
