Origanum onites and Origanum vulgare ssp. hirtum were collected from Balikesir, on the north west of Turkey. The nitrogen contents in organs such as root, stem, leaf and flower of Origanum onites and Origanum vulgare ssp. hirtum taxa in vegetative and generative growth stages were investigated. Nitrogen analyses of soil and plant samples were carried out according to the Kjeldahl method. It was...

The volatile oils of black pepper [Piper nigrum L. (Piperaceae)], clove [Syzygium aromaticum (L.) Merr. & Perry (Myrtaceae)], geranium [Pelargonium graveolens L'Herit (Geraniaceae)], nutmeg [Myristica fragrans Houtt. (Myristicaceae), oregano [Origanum vulgare ssp. hirtum (Link) Letsw. (Lamiaceae)] and thyme [Thymus vulgaris L. (Lamiaceae)] were assessed for antibacterial activity against 25 dif...

The lepton number violating interactions generated by the light Majorana neutrinos can erase the primordial baryon asymmetry of the universe during the electroweak phase transition. The Majorana masses of the left-handed neutrinos are constrained to avoid this problem. These constraints do not depend on the (B−L) symmetry breaking mechanism. 1 e-mail address : [email protected]

background and objectives: essential oils are very complex mixture of components and their composition may vary in different species or varieties or even within the same variety. origanum vulgare l. subsp. vulgare is one of the most distributed subspecies within the genus origanum and has been found to be a poor-oil, categorized in cymyl, bornane or sabinyl chemotypes with higher proportion of ...

The neutrino sector in a left-right extension of the Standard Model depends on how SU(2)R is broken. I list all possible scenarios, including the ones where the Majorana νR mass is naturally much smaller than the SU(2)R breaking scale, which is desirable for generating the proper baryon asymmetry of the Universe. The best such choice is identified and discussed. In the Standard Model of particl...

Neutrino oscillation experiments reveal that neutrinos have very small but finite masses. Since neutrinos have no masses in the standard model, we need to extend the standard model to induce the neutrino masses which coincide with the results of the neutrino oscillation experiments. It is possible that neutrino can have both of Dirac mass and Majorana mass. Majorana mass has the feature that it...
