Lone mothers and the puzzles of daily life: do care regimes really matter?
2010
Kroger T. Lone mothers and the puzzles of daily life: do care regimes really matter? Int J Soc Welfare 2010: 19: 390–401 © 2009 The Author, Journal compilation © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. This article studies childcare patterns and day-to-day strategies of 111 working lone mothers from Finland, France, Italy, Portugal and the UK, and asks whether their arrangements are prescribed by care regimes. Lone mothers' arrangements are grouped into five based on the availability and use of different formal and informal childcare resources. The article argues that, even though lone mothers have a more favourable starting point in Finland and France…
Iron operates as an important factor promoting year-round diazotrophic cyanobacteria blooms in eutrophic reservoirs in the tropics
2021
Abstract We hypothesize that iron availability plays an important role in driving phytoplankton structure and dynamics in tropical reservoir. This role has often been neglected in routine monitoring of water quality since the main focus has been addressed on macronutrients such phosphorus and nitrogen. To elucidate the potential regulation exerted by iron availability on phytoplankton, a limnological investigation was carried out in two neighboring eutrophic reservoirs in tropical China. Traditional physical and chemical variables were measured along with total and dissolved iron concentrations to explore how they could influence phytoplankton structure. Statistical analyses showed that dis…
Structures optiques dissipatives en cavité laser à fibre
2011
This thesis presents a study of the nonlinear dissipative dynamics of localized of self organized structures in passively mode-locked fiber laser through nonlinear polarization evolution. We reveal the existence of a gradual transition from the quasi-cw to mode locked dynamics in the multi-pulsing regime. We emphasize on the intermediate state, where various new dynamics are observed. We study collective behaviors of dissipative solitons in the presence of a continuous background. One of the complex and attractive dynamics presented is the "soliton rain", which composed of three field components : continuous modes of background, drifting of solitons and condensed phase solitons. This dynami…
Requestioning depression in patients with cancer: Contribution of somatic and affective symptoms to Beck's Depression Inventory
2007
Background: Depressive symptoms are a major complaint reported by cancer patients. Somatic and affective symptoms can contribute to depression. Patients and methods: We investigated the prevalence of somatic and affective depressive symptoms with the Beck Depression Inventory (BDI) in 213 hospitalized cancer patients prior to the start of chemotherapy. Results: Seventeen of 213 patients (8%) were screened positive for major depression; 40 (19%) had mild to moderate depressive symptoms. The corresponding figures for somatic and affective symptoms were 33.3% and 2.8% in the patients with major depression and 23.0% and 8.0% in those with mild to moderate depressive symptoms. Female patients, p…
“Randomised trial comparing biweekly oxaliplatin plus oral capecitabine versus oxaliplatin plus i.v. bolus fluorouracil/leucovorin in metastatic colo…
2009
PURPOSE: Oxaliplatin combined with either fluorouracil/leucovorin (OXAFAFU) or capecitabine (OXXEL) has a demonstrated activity in metastatic colorectal cancer patients. We aimed at comparing these two regimens in terms of response rate (RR), safety, progression-free survival (PFS), and quality of life (QoL) of patients. METHODS: A total of 322 patients with metastatic colorectal cancer were randomized to receive biweekly: oxaliplatin 100 mg/m(2) i.v. on day 1, capecitabine 1,000 mg/m(2) orally twice daily from day 1 to day 11 (OXXEL); or oxaliplatin 85 mg/m(2) i.v. on day 1; 6S-leucovorin 250 mg/m(2) i.v. and fluorouracil 850 mg/m(2) i.v. on day 2 (OXAFAFU). RESULTS: Eleven complete and 42…
Diet-Induced Rabbit Models for the Study of Metabolic Syndrome
2019
Simple Summary In recent years, obesity and metabolic syndrome (MetS) have become more prevalent owing to increased unhealthy habits and sedentary lifestyles, becoming public health problems. Experimental studies have allowed us to explore the mechanisms underlying the pathophysiological processes related to MetS. Several research protocols can be carried out with minimal staff, maintenance, and resources in animals such as rabbits. High-fat diets enriched with other components, mainly cholesterol and sugars, result in the rapid development of hypercholesterolemia and vascular alterations as a response to dietary manipulation. Furthermore, other experimental models, including transgenic rab…
Varieties of universalism : post-1990s developments in the initial school-based model of VET in Finland and Sweden and implications for transitions t…
2017
The Nordic countries are often referred to as a group even though their education systems and training models are very different. The aim of this study is to advance understanding of those differences and compare the developments and organisation of initial vocational education and training (IVET) in Finland and Sweden since the 1990s as examples of school-based models of IVET in statist regimes. The research questions address the following: how these two countries have institutionalised school-based IVET since the 1990s; the kinds of legislative reforms that have been decisive for the construction of school-based IVET; and how the models of school-based IVET in these two countries allow ac…
Effect of Urea–Hydrogen Peroxide Content on the Photocatalytic Activity of Zinc Oxide Nanoparticles
2021
ZnO nanoparticles (NPs) were synthesized using zinc acetate dihydrate, ethanol, and oxalic acid as precursor, solvent, and complexing agent, respectively, and urea–hydrogen peroxide (UHP) as, simultaneously, nitrogen precursor and oxygen donor. The structural, morphological, textural, and optical properties of ZnO photocatalysts were investigated using different characterization methods such as XRD, SEM, BET, and UV-Vis-DRS. The XRD patterns showed that the products consisted of ZnO and revealed the presence of nitrogen. SEM images revealed the agglomeration and aggregation of NPs. The photocatalytic activity of ZnO samples was estimated based on the photo-oxidation of 2-propanol under UV i…
Weather Regimes in the Euro-Atlantic and Mediterranean sector and relationship with West African rainfall over the period 1989-2008 from a Self-Organ…
2011
International audience; Weather Regimes (WR) have been defined over the Euro-Mediterranean region [60°W-60°E; 15°N-70°N] from May to October season using the daily Sea Level Pressure, 700 hPa geopotential height and specific humidity from ERA-interim over 1989-2008 period. Computations are based on a neural network lassification technique referred to as Self Organizing Maps and the WR produced can be used by the community for comparison with other periods, projection onto model outputs, seasonal prediction or teleconnection studies. The article particularly examines the relationship between WR and West African (WA) rainfall and our results suggest that changes in particular WR frequencies c…
The sedimentary and remote-sensing reflection of biomass burning in Europe
2018
Aim: We provide the first European-scale geospatial training set relating the charcoal signal in surface lake sediments to fire parameters (number, intensity and area) recorded by satellite moderate resolution imaging spectroradiometer (MODIS) sensors. Our calibration is intended for quantitative reconstructions of key fire-regime parameters by using sediment sequences of microscopic (MIC from pollen slides, particles 10-500 µm) and macroscopic charcoal (MAC from sieves, particles > 100 µm). Location: North-south and east-west transects across Europe, covering the mediterranean, temperate, alpine, boreal and steppe biomes. Time period: Lake sediments and MODIS active fire and burned area…
