Today, the minimum temperature is expected to be 5C in Abu Samra, 6C in Wakrah and Mesaieed, 7C in Al Khor, 11C in Dukhan, 13C
in Doha and 14C in Ruwais.
The 1H and 13C
data of the steroidal nucleus is similar to the compound 1.
In the meantime, the milder conditions of 11C today and 13C
tomorrow look like the calm before this chill sets in.
Summary: Inland temperatures will range between 37C and 33C, dipping as low at 13C
in the mountains.
8 Hz, H7); 13C

Since maize and sugarcane are widely consumed in low- and middle-income countries and already contain a lot of 13C
sucrose, natural enrichment may not be adequate.
Stable isotope studies show less depleted 13C
and coherent 180 for MZKD-2, MZKD-5, MZKD-6, whereas MZKD-3 exhibited relatively less depleted 180 values (-4.
There will also be vastly differing temperatures, with the chance of the mercury hitting 13C
or 14C on Saturday but dropping down to as low as 5C by Monday.
The mercury will rise to around 13C
(55F) at first - but it will be even warmer on Sunday in areas sheltered by high ground.
Resonance assigned by 1H NMR and 13C
NMR spectrum are shown in Table 1 shows pe presence of six mepine carbons C-1 to C-6 and one mepoxy moiety at C-3 (A 3.
The abundance of 18O and 13C
in a sample is conventionally reported as the per mil (=mg/g or ) difference in delta (d) notation (d18O and d13C) between isotope ratios in the sample and those in the international Pee Dee Belemnite (PDB) standard which has d18O and d13C values of 0 (Hudson 1977).
high resolution solid-state NMR has been used to compare these bones in terms of amino acids and analyse these bones at the atomic level.
