LEAD(II) AND CADMIUM(II) REMOVAL FROM AQUEOUS SOLUTIONS USING HAZELNUT AND ALMOND SHELLS SORBENT MATERIALS

2016

Removal of toxic metal ions from natural and waste waters is of great importance for the health of living organisms and for environmental protection. Alternatively to the conventional chemical treatments, such as precipitation, reverse osmosis, etc, biosorption shows a growing interest for toxic metal ions removal from contaminated aqueous solutions. The sorption ability of every type of biomass towards metal ions depends on many variables that characterize the solution. Among these, the ionic strength (I) is one of the most important and cannot be neglected during an accurate adsorption study. For this reason and with the aim of quantitatively define the influence of I, here are reported t…

Daucus carota subsp. maximus (Desf.) Ball from Pantelleria, Sicily (Italy): isolation of essential oils and evaluation of their bioactivity

2021

Daucus is a genus of economically important plants belonging to Apiaceae family spread in temperate regions. Species of this genus are used as food and several biological properties have reported. The chemical composition of the essential oils from different organs (roots, stems and flowers) of Daucus carota subsp. maximus, a species not previously investigated, was analyzed by GC-MS. Our results showed the presence of β-phellandrene as the most abundant component of stems and flowers and of γ-terpinene as a major compound of the oil from the roots. Flower essential oil caused a greater increase in the activity of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) i…

Transnacionālo korporāciju apvienošanās un tā ietekme uz attīstību

2019

Globalizācijas ietekmē, pieaugot korporāciju iespējām veikt darbību starptautiskā mērogā, ir izveidojies ļoti dinamisks un konkurentu bagāts tirgus teju visās industrijās un nozarēs. Lai saglabātu savu konkurētspēju un spētu pielāgoties straujajām pārmaiņām, korporācijām ir bijis jāattīstās un jāaug ļoti straujā tempā. Līdz ar to, ir aktualizējušās apvienošanas un pārņemšanas stratēģijas, ko korporācijas izmanto kā ātrākas izaugsmes un attīstības rīkus, lai nodrošinātu savu konkurētspēju un ieņemtu stabilu vietu savas nozares tirgū. Līdz ar to, pētījuma mērķis ir identificēt transnacionālo korporāciju apvienošanās darījumu ietekmi uz uzņēmumu attīstību. Analizējot divus apvienošanās darījum…

Conceptualizing and Measuring the Perceived Value of an Arts Venue as Applied to Live Performance

2008

International audience; This paper mobilizes the concept of value to investigate the influence of physical surroundings on artistic experiences. First the literature on value is reviewed to ascertain just how useful the concept is for understanding the physical environment. The use of the concept supplements other research perspectives on the issue of physical surroundings (sensorial marketing, appropriation). There follows a presentation of the various stages in constructing a scale of perceived value applied to live performances. The paper concludes with a discussion of results (contributions, management implications, research limits, and avenues for further inquiry).

L'Oscillation de Madden-Julian et la variabilité pluviométrique régionale en Afrique Subsaharienne

2007

The role of the Madden-Julian Oscillation ("MJO") on rainfall variability in Sub-Saharan Africa is examined, based on daily rain-gauge records and the NCEP-DOE AMIP-II reanalyses. The convective and dynamical signal associated with the MJO is extracted using two differing methodologies, the BMRC daily indices (Wheeler & Hendon 2004) on the one hand, and a Local Mode Analysis ("LMA", Goulet & Duvel 2000) on the other hand. The temporal variability of the MJO (in terms of period, amplitude, seasonality and location of the convective anomalies) is first analysed. Though the overall amplitude of the signal is not related to El Niño, the oscillations occurring under El Niño (La Niña) conditions …

Theoretical and experimental studies of some main group compounds : from closed shell interactions to singlet diradicals and stable radicals

2012

Acquiring knowledge of different interactions within and between molecules is a fascinating undertaking as it not only deepens our understanding of chemical bonding but also offers insight into electronic structures, molecular properties and the connections between these two. This dissertation combines together three main group chemistry related topics within the aforementioned theme. Research presented in the first third of this dissertation describes wave function and density functional theory studies of weak inter- and intramolecular interactions in pnictogen-based dimers X3Pn···PnX3 (Pn = N-Bi; X = F-I), dithallenes RTlTlR (R = H, Me, tBu, Ph) and octachalcogen dications Ch82+ (Ch = S, …
