Outdoor scale-up of Leptolyngbya sp.: Effect of light intensity and inoculum volume on photoinhibition and -oxidation by Schipper, Kira

“…Indoor, the strain was capable of growing at light intensities of up to 5600 µmol photons/m2/s, at inoculation densities as low as 0.1 g/L (10% inoculation volume vol/vol). Levels of chlorophyll and phycocyanin showed a significant decrease within the first 24 h, indicating some level of photooxidation, however, both were able to recover within 72 h. …”

Cultivating microalgae in desert conditions: Evaluation of the effect of light‐temperature summer conditions on the growth and metabolism of nannochloropsis qu130 by Jabri, Hareb Al

“…In the Qatar desert the temperature varies widely, typically between 10° and 45 °C There are also wide variations in light intensity, with values of over 1500 μmolhν.m−2s−1 in summer. A study of the effects of these thermal and light fluctuations is therefore essential for large‐scale outdoor production systems, especially during the summer when temperature and light fluctuations are at their highest. …”

Concrete Pavement Truck Equivalence Factors For Upgrades by Razouki, Sabah Said

“…Presented in this paper are the upgrade truck equivalence factors for single unit trucks of type, 1.2 and 1.22 which are not covered by AASHTO. The equivalency factors for front and rear axles of single unit trucks were developed using AASHO Road Test equation after considering the decrease in front axle load and the increase in rear axle load due to the axle load redistribution on upgrades. …”

Pilot-scale petroleum refinery wastewaters treatment systems: performance and microbial communities' analysis by Karray, Fatma

“…The reduction of the COD, BOD5, phenols, and the total petroleum hydrocarbon (TPH) reached 82.10%, 85.87%, 91.63%, and 81.11%, respectively at high hydraulic residence time (HRT = 10 days). Decreasing HRT to 5 and 2.5 days led to a decrease in the efficiency of the process and a decrease in biomass concentration was also observed (<1000 mg/l). …”

Cutaneous Aβ-Non-nociceptive, but Not C-Nociceptive, Dorsal Root Ganglion Neurons Exhibit Spontaneous Activity in the Streptozotocin Rat Model of Painful Diabetic Neuropathy . by Djouhri, Laiche

“…Compared with control, we found in STZ-rats with established pain hypersensitivity (5 weeks post-STZ) several significant changes including: (a) A 23% increase in the incidence of spontaneous activity (SA) in Aβ-LTMs (but not C-mechanosensitive nociceptors) that may cause dysesthesias/paresthesia suffered by DPNP patients, (b) membrane hyperpolarization and a ∼85% reduction in SA rate in Aβ-LTMs by K7 channel activation with retigabine (6 mg/kg, i.v.) suggesting that K7/M channels may be involved in mechanisms of SA generation in Aβ-LTMs, (c) decreases in AP duration and in duration and amplitude of afterhyperpolarization (AHP) in C-and/or Aβ-nociceptors. …”
