The incidence of elbow injury experienced by baseball pitchers is on the rise. Biomechanical investigations focusing on the acceleration phase of the pitch have yet to elucidate a singular cause for these injuries. Leading to the question is there an additional significant stress on the elbow during other phases of the pitch? This study sought to d...

The present study was aimed to investigate brilliant green (BG) dye sorption onto soybean straw biochar (SSB) prepared at 800 °C and further understanding the sorption mechanism. Sorption kinetic models such as pseudo-first and pseudo-second order were executed for demonstrating sorption mechanism between the dye and biochar. Results of kinetics st...

Diverse aromatic mediators have often been used to increase the degradation of organic pollutants by Fenton reaction (Fe2+ + H2O2 → Fe3+ + HO● + HO−). The presence of reducing mediators can minimize the accumulation of Fe3+ in solution, which leads to accelerated Fe2+ regeneration and enhances the generation of reactive oxygen species, such as the ...

Unimolecular pyrolysis of isopropyl acetate (IPA) and isopropyl propanoate (IPP) esters as biodiesel surrogates has been carried out using density functional theory (DFT) at BMK/DZ, TZ level and CBS-QB3 ab initio calculations. Results were compared with isopropyl butanoate (IPB). The rate constants for unimolecular decomposition reactions are calcu...

The volumetric adsorption kinetics of carbon dioxide (CO2) onto the synthesized palm kernel shell activated carbon via single-stage CO2 activation and commercial Norit® activated carbon were carried out at an initial pressure of approximately 1 bar at three different temperatures of 25, 50, and 100 °C. The experimental kinetics data were modelled b...

We assessed the duration and baseline determinants of antibody responses to SARS-CoV-2 spike antigens and the occurrence of reinfections in a prospective cohort of 173 Spanish primary health care worker patients followed initially for 9 months and subsequently up to 12.5 months after COVID-19 symptoms onset. Seropositivity to SARS-CoV-2 spike and r...

Ending the COVID-19 pandemic will require long-lived immunity to SARS-CoV-2. Here, we evaluate 254 COVID-19 patients longitudinally up to eight months and find durable broad-based immune responses. SARS-CoV-2 spike binding and neutralizing antibodies exhibit a bi-phasic decay with an extended half-life of >200 days suggesting the generation of long...

In the present work, we have developed a mesoporous silicalite-1 using CMC as a template for the removal of MB from aqueous solution. The synthesized silicalite-1 were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravim...

The present study aimed primarily to demonstrate the potential use of mastic tree leaves from which the essential oils have been extracted to remove rhodamine B and ethyl violet from aqueous solutions through biosorption. Pistacia lentiscus (the mastic tree) is widespread in the Mediterranean region. Chemical characterization of the biosorbent was ...
