In the minimal extension of the standard electroweak theory with ultra massive Majorana neutrinos, the process e− + e− → μ− + μ− could be observable, in sharp contrast with the reaction e− + e− → W−+ W− which is entirely controlled by neutrinoless double beta decay ββ0ν data. Our result provides the process background that must be confronted ”new physics” models which postulate doubly charged p...

The standard model (SM) of particle physics successfully describes a variety of phenomena in terms of a few fundamental quantities. Besides the gauge coupling constants associated to the fundamental interactions, and the scalar sector responsible for spontaneous electroweak symmetry breaking, the major part of adjustable parameters are related to the fermion sector describing the masses and mix...

Superheated water extraction is used to extract essential oil of leaves of Origanum micranthum. The effect of different temperatures on the essential oil profile and rate of extraction as a function of time is investigated. The components of essential oil of Origanum micranthum are removed from the aqueous extract by C18 solid-phase extraction. The identification of components is carried out us...

results modern investigations have supported the claims of the insecticidal activity of several plants, including allium sativum, artemisia absinthium, citrullus colocynthis, laurus nobilis, mentha pulegium, myrtus communis, nerium oleander, ocimum basilicum, and origanum majorana. however, in the cases of plants like iris florentina and malva sylvestris, there is not enough evidence in modern ...

High-valued medicinal plants Achillea millefolium, Acorus calamus, Arnebia nobilis, Fumaria indica, Gymnema sylvestre, Origanum vulgare, Paeonia emodi, Peganum harmala, Psoralea corylifolia, Rauwolfia serpentina, and Vetiveria zizanioides were identified with the help of taxonomical markers and investigated for characterization and palynological studies. These parameters are used to analyze the...

Bu çalışma, kekik (Origanum onites L.) ve biberiye (Rosmarinus officinalis bitkilerinden elde edilen uçucu yağların Fusarium solani‘ye karşı antifungal aktivitesini tespit etmek amacıyla laboratuvar ortamında yürütülmüştür. Bitkilerden yağlar 1, 2 4 μl dozunda otoklav Patates Dekstroz Agar (PDA) besi yerine ilave edilmiştir. Patojenlere ait 8 mm çapında miselyum diskleri PDA yerlerine ekilmişti...

O6-alkylguanines are potent mutagenic, pro-carcinogenic and cytotoxic lesions induced by exogenous and endogenous alkylating agents. A facilitated elimination of these lesions by increasing the activity of O6-methylguanine-DNA methyltransferase (MGMT) is likely to be a beneficial chemoprevention strategy, which, however, has not been examined. Because, a marginal enhancement of this protein may...

Pijushpani Bhattacharjee, Narendra Sahu, and Urjit A. Yajnik Department of Physics, Indian Institute of Technology, Bombay, Mumbai 400076, India and Indian Institute of Astrophysics, Bangalore-560 034, India Abstract Cosmic strings arising from breaking of the U(1)B−L gauge symmetry that occurs in a wide variety of unified models can carry zero modes of heavy Majorana neutrinos. Decaying and/or...
