Chemical Composition of the Essential Oil of Bupleurum Fontanesii (Apiaceae) Growing Wild in Sicily and its Activity on Microorganisms Affecting Hist…
2016
Hydrodistillation of the flowers (BpFl) of and fruits (BpFr) of Bupleurum fontanesii Guss. ex Caruel gave two oils that were analyzed by GC and GC-MS. The main components were α-elemol (16.7%), caryophyllene oxide (16.4%) and heptacosane (15.9%) in BpFl, and spathulenol (16.8%), caryophylladienol I (13.2%) and α-elemol (12.8%) in BpFr. A good antimicrobial activity against several microorganisms, including Bacillus subtilis, Staphylococcus aureus, Fusarium oxysporum and Aspergillus niger, all infesting historical art craft, was also determined.
Chemical composition and biological activity of the essential oil of Ballota hispanica (L.) Benth. growing wild in Sicily
2015
Ballota L. comprises several relevant species largely used for their excellent therapeutic properties. Ballota hispanica (L.) Benth. is widely used in herbal medicine, and it is sold in herbalist shops for its sedative and antispasmodic properties. Considering its traditional medicinal use and the lack of scientific studies on the volatile components of this species as well as on its biological activities, in this study the chemical composition of the essential oil from aerial parts of B. hispanica, collected in Sicily, was evaluated by gas chromatography and gas chromatographyâmass spectrometry. α-Elemol was the most abundant component of the oil (10.9%), followed by α-ylangene (8.5%),…
Stepmothers’ constructions and negotiations of belonging
2017
Applying a narrative approach and symbolic interactionist frame of reference, this study examines how Finnish stepmothers in their written narratives construct and negotiate their belonging. Belonging is a relevant concept in this study since it focuses on social interaction and intersubjectivity, and their emotional content. Three types of belonging were identified: (a) restricted belonging, (b) dyadic stepmother–stepchild belonging and (c) the spousal relationship as a focal dyad of belonging. Attainment of belonging may be especially challenging for stepmothers owing to their dependence on the willingness of the biological mother and father to share the emotional dimension of the parent–…

Ääntelemällä tapahtuva kommunikointi voi altistaa linnut saalistukselle, koska pedot voivat paikantaa saaliseläimet ääntelyn perusteella. Yksi mahdollinen tapa suojautua saalistajilta on liittyminen parviin. Parveutuminen voi vaikuttaa ääntelyfrekvensseihin lisääntyneen parvensisäisen kommunikointitarpeen kautta, mutta myös koska ääntely suuremmissa parvissa voi olla saalistusriskin suhteen turvallisempaa. Tässä tutkimuksessa tutkin lajienvälisen sekaparven koon vaikutusta töyhtötiaisen pitkän etäisyyden kommunikointiin yleensä, parven sisäiseen kommunikointiin ja parvien väliseen reviirinpuolustuskommunikointiin. Tutkimusmenetelmänä oli töyhtötiaisparvien tarkkailu luonnollisissa olosuhtei…
