This study evaluated the distribution of particulates (PM1, PM 2.5, 4, 7, 10, and TSP) around smallholder gari production facilities in Niger Delta, Nigeria. The were at 3 distances (3.05, 7.62, 15.24 m) from emission source dry season (November, January, March) wet (May, July, September) Bayelsa, Rivers, Abia states. A mini-volume air sampler was used to assess concentration particulates, whil...

We study the roots of a random polynomial over field $p$-adic numbers. For monic with i.i.d. coefficients in $\mathbb{Z}_p$, we obtain an estimate for expected number this polynomial. In particular, if take values $\pm1$ equal probability, converges to $\left(p-1\right)/\left(p+1\right)$ as degree tends $\infty$.

Exposure to single air pollutant and physical activity (PA) were associated with an altered mitochondrial DNA copy number (mtDNA-CN). However, studies on the interactive effects of or a mixture pollutants PA mtDNA-CN limited. A total 2707 Chinese adults obtained from Henan Rural Cohort Study. Spatiotemporal models used estimate particulate matter (PMs) (PM aerodynamic diameter ? 1.0 ?m (PM1), ?...

Air pollution is the principal environmental threat to public health in UK. Ever-increasing evidence links ambient air pollutants, preventable diseases, and inequalities. Children are particularly vulnerable harmful effects due their short height, developing lungs, higher rate of respiration. Using data from quality monitors around schools, we investigated 2018–2019 NO2, PM10, PM2.5, PM1 concen...

The Juno orbiter continues to collect data on Jupiter's gravity field with unprecedented precision since 2016, recently reporting a non-hydrostatic component in the tidal response of planet. At mid-mission perijove 17, registered Love number $k_2=0.565\pm0.006$ that is $-4\pm1\%$ ($1\sigma$) from theoretical hydrostatic $k_2^{(hs)}=0.590$. Here we assess whether aforementioned departure tides e...

Objective: The SARS-CoV-2 virus has infected many healthcare professionals. Endoscopy is an aerosol-generating procedure and the endoscopy team at risk of exposure infection. We describe leak-testing aerosol box that uses a glove-covering for endoscope.Materials Methods: An endoscopic with over endoscope was made gastroscopy, EUS ERCP procedures tested leakage aerosol/airborne particles. Fine p...
