Concentration of chromium and nickel in serum of patients with orthopedic implant: An analysis
2021
Introduction: Surgical corrections of fracture using fixation devices made from various alloys (stainless steel, cobalt-chromium alloys, and titanium) carry a risk of these alloys leaching into circulation, potentially causing undesired health effects. Hence, monitoring the levels of metal ions in the serum of postoperative patients with metal implants is mandated. Materials and Methods: Blood samples from seventy patients with orthopedic metal implants was collected after a minimum postoperative period of 1 year. The samples were subjected to triple acid digestion and serum levels of chromium and nickel were analyzed using inductively coupled plasma-mass spectrometry. Results: The concentr…
Determination of selenium, zinc and cadmium in antidandruff shampoos by atomic spectrometry after microwave assisted sample digestion
2000
Microwave assisted pre-treatments for atomic spectrometric determination (inductive coupled plasma-optical emission spectrometry, ICP-OES or flame atomic absorption spectrometry, FAAS) of metallic elements, usually present in antidandruff shampoos, are proposed. They are based on the digestion of the sample with HNO(3) into a closed reactor, which is irradiated at 800 W for a few minutes. Selenium was determined by ICP-OES. The limit of detection was 0.11 mg l(-1); the relative standard deviation (R.S.D.) for the selenium content in the samples was in the 0.6-3.6% range. The results obtained were in agreement with the label contents and the recovery of the proposed method was in the 100-106…
Determination of copper, iron, molybdenum and silicon in hydrometallurgically roasted molybdenite concentrate solution by inductively coupled plasma …
1997
Abstract Inductively coupled plasma atomic emission spectrometry has been applied for the estimation of major constituents in molybdenite concentrate solutions produced by hydrometallurgical alkaline digestion. Copper, iron, molybdenum and silicon were considered as major constituents to be determined. Multiple linear regression was utilized for the control of matrix effects. Using simple acid-based standards, all the elements investigated could be determined with satisfactory results using an appropriate method of calculation.
The measurement of impurities in silicon for solar cell production
2012
The power conversion efficiency of solar cells is largely dependent on impurity levels in silicon. In the current investigations two sample preparation methods of silicon had been used before analysis - acid dissolution at atmospheric pressure and pressured microwave assisted technique. Quantification of impurities in solar silicon was done by inductively coupled plasma mass spectrometry and electrothermal atomic spectrometry. Microwave assisted dissolution of solar silicon was more effective compared to the traditional dissolution method on the hot plate, but complete dissolution of impurities and silicon matrix was achieved with a nitric and hydrofluoric acid mixture. The mass of solar si…
On the Fast and Rigorous Analysis of Compensated Waveguide Junctions Using Off-Centered Partial-Height Metallic Posts
2007
In this paper, we present an efficient and rigorous method, based on the 3-D boundary integral-resonant-mode expansion technique, for the analysis of multiport rectangular waveguide junctions compensated with partial-height cylindrical metallic posts. The electrical performance of a great variety of commonly used wideband microwave circuits has been improved drastically thanks to the introduction of a new design parameter, i.e., the relative position of the metallic post in the structure. To the authors' knowledge, this parameter has not been taken into account in previous studies concerning compensated junctions using partial-height metallic posts. The developed tool has been successfully …
La sostenibilità della coppia mista fra familiare e sociale
2013
La ricerca analizza sia i processi macrosociali, riferiti alla comunità, sia i processi micro, propri della dinamica di coppia. Per i primi abbiamo esaminato la percezione di diversità che può scaturire dalle dinamiche intergruppali e l’identità di luogo (intesa come radicamento nel nuovo contesto di accoglienza); per le dinamiche di coppia si sono prese in esame l’impatto che la presenza dei figli genera sulla dinamica di coppia e gli stili educativi adottati. Coerentemente con il metodo d’indagine della ricerca qualitativa, sono state intervistate 22 coppie miste residenti in Sicilia. Il contenuto emerso è stato analizzato con l’ausilio del software Atlas.ti. Tra gli aspetti più salienti …
What is your couple type? Gender ideology, housework-sharing, and babies
2015
AbstractBACKGROUNDIt is increasingly acknowledged that not only gender equality but also gender ideology plays a role in explaining fertility in advanced societies. In a micro perspective, the potential mismatch between gender equality (i.e., the actual sharing taking place in a couple) and gender ideology (i.e., attitudes and beliefs regarding gender roles) may drive childbearing decisions.OBJECTIVEThis paper assesses the impact of consistency between gender equality in attitudes and equality in the division of household labour on the likelihood of having another child, for different parities.METHODSRelying on two-wave panel data of the Bulgarian, Czech, French, Hungarian, and Lithuanian G…
Charge radii of exotic potassium isotopes challenge nuclear theory and the magic character of N = 32
2020
Nuclear charge radii are sensitive probes of different aspects of the nucleon-nucleon interaction and the bulk properties of nuclear matter; thus, they provide a stringent test and challenge for nuclear theory. The calcium region has been of particular interest, as experimental evidence has suggested a new magic number at $N = 32$ [1-3], while the unexpectedly large increases in the charge radii [4,5] open new questions about the evolution of nuclear size in neutron-rich systems. By combining the collinear resonance ionization spectroscopy method with $\beta$-decay detection, we were able to extend the charge radii measurement of potassium ($Z =19$) isotopes up to the exotic $^{52}$K ($t_{1…
Somatic Interventions and Depth of Experiencing in Emotionally Focused Couple Therapy
2022
Emotionally Focused Couple Therapy (EFT), an attachment-based couple therapy, views emotion as being central to the process of therapeutic change. As affect arousal of emotion is a somatic reaction, the purpose of this study was to focus on therapists’ interventions classified as noting and commenting on clients’ somatic cue of emotional experience, such as their facial expression or posture, in relation to depth of emotional experiencing demonstrated by clients in EFT couple therapy sessions. The sample included 13 therapists, each treating one couple during a single EFT training demonstration session. We coded therapists’ interventions (i.e., commenting on one partner’s somatic cue of emo…
Relational dialectics in intercultural couples' relationships
2012
The main purpose of this study is to describe and to understand the intercultural couples’ relationships in Finland from the relational-dialectics perspective by Baxter and Montgomery (1996). Following the interpretive research tradition, in this qualitative study, data were collected from 18 heterosexual intercultural couples (36 persons), utilizing the multi-method approach. The multi-method approach in this study includes theme interviews (5 couples), concept map interviews (six couples) and e-mail interviews (seven couples). The data were analyzed following an inductive content analysis approach. The intercultural couples in this study experienced internal and external dialectics, relat…
