Caffeine use or napping to enhance repeated sprint performance after partial sleep deprivation: Why not both? by Romdhani, Mohamed

“…Purpose: To compare the effect of a 20-minute nap opportunity (N20), a moderate dose of caffeine (CAF; 5 mg·kg-1), or a moderate dose of caffeine before N20 (CAF+N) as possible countermeasures to the decreased performance and the partial sleep deprivation-induced muscle damage. …”

Conversion of Organic Municipal Wastes into Biochars and their Effect on Fertility Parameters of Normal and Sabkha Soils of Qatar by Ahmedna, Mohamed

“…To each pot, sufficient amount of 0.25-mm sieved biochar was mixed with soil to yield carbon to soil ratios of 0, 1, and 2% (wt/wt). Box-Behnken experimental design was used instead of the full factorial to decrease the number of treatments to a manageable level (126 treatments) with three replications at the center. …”

Investigating the utilization of healthcare services to manage respiratory tract infections (RTIs) among Qatari patients attended selected primary healthcare centers in Qatar by Islam, Nazmul

“…We have found no difference in the month-to-month rates of RTI-related GP visits (per 1000 total visits) over the study period (non-significant decreasing trend). However, there was a significant decreasing trend in the monthly rates of antibiotics consumption and an increasing trend in the tests/investigations done but there was no clear increasing or decreasing trend in the monthly rates of other medications use. …”

Kappa-Distributed Electrons in Solar Outflows: Beam-Plasma Instabilities and Radio Emissions by Lazar, M.

“…The frequency downshift, also revealed by the observations, clearly tends to increase in the presence of a Kappa-distributed beam. Particle-in-cell (PIC) simulations confirm the inhibiting effects of (initially) Kappa-distributed electrons, but these minor effects in the linear and quasi-linear phases unexpectedly lead to significant decreases in the wave energy levels of the (primary) ES fluctuations near the plasma frequency and higher harmonics. …”
