Levels and Potential Health Hazards of Chlorinated Pesticidesin Surface Water Samples of Charsadda Area of Pakistan Using SPME-GC-ECD Technique

2021

In the present study, we determined the levels of chlorinated pesticide residues in surface water samples collected from the Charsadda district (KPK, Pakistan). SPME-GC-ECD with COMBI PAL CTC autosampler was used for extraction and analysis of 20 organochlorine pesticides in the collected water samples. For maximum efficiency of the SPME procedure, several parameters were studied, including the extraction and desorption time of the fiber, solution pH, agitation of samples, and stirring speed, etc. This method showed good liner response, with R2 values in the range of 0.9887 to 0.9999 for all pesticides. This method also provided good percent recoveries at 1 µg L−1 (87.5 to 106.0%) and at 2 …

Una más de la familia. Au pairs atrapadas entre el capital humano y la economía moral

In the present text we approach the discourses of young women who came out as au pairs. The characteristics of this figure place it in a space halfway …

Le famiglie di soggetti autistici, le giovani donne affette da disturbi del comportamento alimentare, gli alcolisti, i tossicodipendenti, i giovani a rischio devianza dei quartieri degradati e coloro che usufruiscono delle misure alternative alla detenzione sono alcune degli attori che, venendo a far parte di nuovi aggregati identitari, mappano i contesti locali in spazi simbolici, in localitè, società urbane incomplete che rinviano a nuove questioni sociali e a differenti derive cui il welfare locale cerca di rispondere. Nel tentativo di esplicitare il groviglio fra solidarietà e povertà, capitalizzazione dei legami e inadeguatezza della rete, progettualità sociale e limiti organizzativi, …

Gli strumenti di conciliazione nella prassi: analisi su un campione di contratti collettivi aziendali

2020

Individuare le vie verso un efficiente sistema di work-life balance è questione complessa e impone di considerare molteplici fattori, tra cui il ruolo strategico che può assumere la contrattazione collettiva nell’integrazione delle misure adottate a livello normativo, perfezionando la disciplina con diritti mirati o per meglio garantire l’attuazione di quelli esistenti. Fino a che punto, però, i contratti collettivi raggiungano nei fatti l’ambizioso obiettivo di potenziare i risultati in questa direzione è ciò che si intende meglio indagare, pur senza pretesa di esaustività. Il presente contributo si concentra sull’analisi dei contenuti di un campione di contratti collettivi di secondo live…

Evidence for strong immediate well-being effects of choral singing – With more enjoyment for women than for men

2009

Choral singing as a leisure activity is associated with increased well-being effects. It is also known that women engage more often in singing activities than men do. The objective of the study was to investigate how emotional states vary on pre and post measurements of a regular choral rehearsal in groups of female and male choral singers. Participants were 212 individuals (women n=152, men n=60) from eleven choirs (amateur n=6, advanced n=5). Results showed that in accordance with the literature on emotions and gender, women reported significantly more positive emotional states than men did related to participating in a regular choral rehearsal. However, few differences were found. Moreov…

Agronomical evaluation of Sicilian biotypes of Lavandula stoechas L. spp. stoechas and analysis of the essential oils

2015

The aim of this study was to characterize wild lavender, which was collected in three different areas of Sicily (Italy),according to agronomic and chemical evaluation. The collection sites were located in Pantelleria island, Partinico (a warm sub-area of Lauretum) and Castelbuono (a middle sub-area of Lauretum). All the populations were identified as Lavandula stoechas L. ssp. stoechas. Essential oils were extracted by hydrodistillation and analyzed by gas chromatography– flame ionization detector (GC–FID) and GC–mass spectrometry (GC–MS). GC–FID and GC–MS analyses permitted the identification of 101 components from the essential oils. We analyzed only the flowers and leaves of L. stoechas …

Essential oil crops for sustainable agriculture - A review

2009

Multifunctionality and diversification of farming systems, integration of agricultural practices both inter se and with the non-agricultural productive systems operating on the territory, biodiversity safeguards, and reduction in off-farm inputs, are key factors for all modern development strategies in agricultural areas. Such issues are valid worldwide, but are especially true in areas in which the cultivation of the more widespread and “classical” crops is constrained by factors of varying degree and importance. In Mediterranean areas, where many environmental and economic factors often reduce rural areas to marginal conditions, the search for new crop opportunities has become one of the …
