Sorption and mechanism studies of Cu2+, Sr2+ and Pb2+ ions on mesoporous aluminosilicates/zeolite composite sorbents
2020
The research aimed to develop a novel mesoporous aluminosilicate/zeolite composite by the template co-precipitation method. The effect of aluminosilicate (AlSi) and zeolite (NaY) on the basic properties and adsorption capacity of the resultant composite was conducted at different mass ratios of AlSi/NaY (i.e., 5/90, 10/80, 15/85, 20/80, and 50/50). The adsorption characteristics of such composite and its feedstock materials (i.e., aluminosilicates and zeolite) towards radioactive Sr2+ ions and toxic metals (Cu2+ and Pb2+ ions) in aqueous solutions was investigated. Results indicated that BET surface area (SBET), total pore volume (VTotal), and mesopore volume (VMeso) of prepared materials f…
Rationale and design of the DARWIN-T2D (DApagliflozin Real World evIdeNce in Type 2 Diabetes): A multicenter retrospective nationwide Italian study a…
2017
Background Randomized controlled trials (RCTs) in the field of diabetes have limitations inherent to the fact that design, setting, and patient characteristics may be poorly transferrable to clinical practice. Thus, evidence from studies using routinely accumulated clinical data are increasingly valued. Aims We herein describe rationale and design of the DARWIN-T2D (DApagliflozin Real World evIdeNce in Type 2 Diabetes), a multicenter retrospective nationwide study conducted at 50 specialist outpatient clinics in Italy and promoted by the Italian Diabetes Society. Data synthesis The primary objective of the study is to describe the baseline clinical characteristics (particularly HbA1c) of pa…
Potential-assisted deposition of mixed alkanethiol self-assembled monolayers
2010
Abstract Preparation of self-assembled monolayers (SAMs) usually involves passive incubation. The recently developed potential-assisted deposition is indeed more selective as well as 100-fold faster than passive adsorption, thereby enhancing the reproducibility of the monolayer deposition. This article aims to identify the electrodeposition conditions necessary to prepare mixed alkanethiol SAMs on gold surface. Parameters such as concentrations in solution, electrode polarization and deposition time were examined for two chain lengths, C 3 (mercaptopropionic acid, MPA) and C 18 (octadecanethiol, ODT). The kinetics and composition of the SAMs were systematically characterized by reductive st…
The Influence of Agricultural Support on Sale Prices of French Farmland: A Comparison of Different Subsidies, Accounting for the Role of Environmenta…
2013
In this paper, using data from individual transactions for the period 1994-2010 in the French NUTS2 region Brittany, we investigated how environmental regulations and transaction land regulations influence the price of sold plots. Regressions on three sub-samples of buyers were performed in order to assess whether different buyers have different attitude or plans regarding the farmland purchased: a sub-sample including only farmer buyers, a sub-sample including non-farmer individual buyers, and a sub-sample including non-farmer nonindividual buyers. Estimations were performed ignoring and accounting for spatial interactions (model SARAR). Results indicate that the price of land decreases wh…
Kriminālsods- probācijas uzraudzība
2021
Bakalaura darba „Kriminālsods – probācijas uzraudzība” tēma ir aktuāla, jo no 2022.gada 1.janvāra Krimināllikumā veiks izmaiņas, probācijas uzraudzību nosakot kā pamatsodu un papildsodu. Darba mērķis ir analizēt probācijas uzraudzības regulējumu Latvijā un salīdzināt ar regulējumu ārvalstīs. Darbā rasti priekšlikumi probācijas uzraudzības pilnveidošanai, piemēram, papildināt Latvijas Sodu izpildes kodeksu, paredzot, ka probācijas uzraudzības laikā notiesātajam var piemērot pienākumus, kas nav noteikti likumā. Darba uzdevumi ir izpētīt probācijas uzraudzības institūta attīstību, analizēt probācijas uzraudzības tiesisko regulējumu Latvijā, pētīt tiesu praksi un izanalizēt tiesisko regulējumu …
El efecto moderador de la edad en la relación entre el valor percibido, las TIC del minorista y la lealtad del cliente
2010
AbstractInformation and communication technology (ICT) may represent a source of benefits for retailers. However, there is a debate in the literature on how ICT influences customer-supplier relationships. In addition, the evidence on the effect of age on consumer attitudes towards retail technological solutions is not conclusive. This paper proposes and tests a model to analyze the influence of retail ICT on consumer loyalty towards the retailer, as well as to assess the moderating role of consumer age on this relationship. As a result, customer assessment of retail ICT, together with perceived value, exerts a positive influence on consumer commitment and satisfaction, being the latter an a…
Physicochemical investigation of surfactant-coated gold nanoparticles synthesized in the confined space of dry reversed micelles
2006
Abstract Gold nanoparticle/surfactant composites have been synthesized by a novel reduction reaction in the confined space of dry sodium bis(2- ethylhexyl)sulfosuccinate (AOT) or lecithin reversed micelles dispersed in n-heptane and cyclohexane, respectively. The reaction was carried out by adding an opportune amount of anhydrous hydrazine/tetrahydrofuran solution to a suspension of HAuCl4-containing dry reversed micelles dispersed in organic solvent. UV–vis investigation ascertained the formation of stable metal gold nanoparticles and the analysis of FT-IR spectra highlighted the formation of an oriented surfactant monolayer at the nanoparticle surface. Simple evaporation under vacuum of t…
The Influence of Nanoparticle Shape on Protein Corona Formation
2020
Nanoparticles have become an important utility in many areas of medical treatment such as targeted drug and treatment delivery as well as imaging and diagnostics. These advances require a complete understanding of nanoparticles' fate once placed in the body. Upon exposure to blood, proteins adsorb onto the nanoparticles surface and form a protein corona, which determines the particles' biological fate. This study reports on the protein corona formation from blood serum and plasma on spherical and rod‐shaped nanoparticles. These two types of mesoporous silica nanoparticles have identical chemistry, porosity, surface potential, and size in the y ‐dimension, one being a sphere and the other a …
Photoluminescent Detection of Human T-Lymphoblastic Cells by ZnO Nanorods.
2020
The precise detection of cancer cells currently remains a global challenge. One-dimensional (1D) semiconductor nanostructures (e.g., ZnO nanorods) have attracted attention due to their potential use in cancer biosensors. In the current study, it was demonstrated that the possibility of a photoluminescent detection of human leukemic T-cells by using a zinc oxide nanorods (ZnO NRs) platform. Monoclonal antibodies (MABs) anti-CD5 against a cluster of differentiation (CD) proteins on the pathologic cell surface have been used as a bioselective layer on the ZnO surface. The optimal concentration of the protein anti-CD5 to form an effective bioselective layer on the ZnO NRs surface was selected. …
