• One-pot sol-gel route to obtain ?-Fe 2 O 3 coatings using glycerol as a steric agent. Structural and magnetic correlations of iron oxides with densification temperature. Advanced characterization CRM XAS techniques. Epsilon oxide (?-Fe ) on Si(100) substrates are obtained by an easy one-pot recipe assisted in acid medium. Glycerol, given its small dimensions, enables the formation nanoparticl...

BACKGROUND Medium chain length (C6-C12) α,ω-dicarboxylic acids (DCAs) and corresponding esters are important building blocks for the polymer industry. For DCAs of 12 carbon atoms and longer, a sustainable process based on monooxygenase catalyzed ω-oxidation of fatty-acids has been realized. For medium-chain DCAs with a shorter chain length however, such a process has not been developed yet, sin...

Batch cultures of mouse LS cells were grown in suspension at controlled dissolved oxygen partial pressures (pOt). At low pOt (i-6 mmHg) the growth and respiration rates and the final cell population were all limited. At high pOt (320 mmHg), cell division was inhibited after an initial doubling of the cell number. At intermediate values of pOt, the growth rate was constant but the final cell pop...

Effect of cooking, fermentation, dehulling and the use of utensils on flavonoids (quercitin and pelargonidin) - antioxidants present in pearl millet (Pennisetum typhoideum) rabadi, along with proximate composition and sensory acceptability of the product were studied. Study revealed an increased ash and flavonoids and reduced crude fibre after cooking in all samples, while fermentation enhanced...

A simple and efficient one-pot three-component synthesis of the biologically important spirooxindole-4H-pyrans was carried out by the reaction of isatin, activated methylene reagents, and 4- hydroxycoumarin in aqueous medium. SBA-Pr-NH2 was found to be an efficient heterogeneous nanoporous solid basic catalyst (pore size of 6 nm) which can be easily handled and removed from the reaction mi...

BACKGROUND & OBJECTIVES Sputum acid-fast bacilli (AFB) microscopy services are not available in all health facilities. Alternative procedures are needed to transport sputum samples to the diagnostic centres for detection of AFB. The objective of the present study was to evaluate sputum smears made by pot-method with the direct smears made immediately after sputum collection by Ziehl-Neelsen (ZN...

My girlfriend tells me she uses marijuana to calm herself if she is having a stressful day. She has been doing this for many years. She says smoking pot is like self-medicating ? it is better than using anti-depressants. She also claims smoking pot helps with depression because of how it helps produce serotonin in the body. What is serotonin and how does it help depression? Does smoking pot rea...
