Obesity in children is a health crisis because the problem is increasing in most developed countries. This study measures the relationship between body mass index (BMI) of children aged 7 - 12 years residing in Luxembourg and the weight and socioeconomic status of their parents. The data used are from the 2007 Socio-Economic Panel Liewen zu L?tzebuerg/European Union-Statistics on Income and Living Conditions survey, which covers a population of approximately 10,000 people. The study sample includes 775 children whose weight and height were recorded to calculate their BMI. The descriptive analysis with the socioeconomic distribution of the children’s BMI and the multilevel logistic regression of the probability to be in overweight or obese were performed. The mean BMI of children was 17.4 kg/m2 for boys and girls. The prevalence of overweight was 21.2% (including 3% who were obese). Weight status, educational level, physical activity, and eating habits of parents were associated with BMI in children. Furthermore, children of foreign nationality had 2.9 times more risk to be overweight or obese than other children of Luxembourg nationality (OR = 2.90, 95%CI: 1.38 - 6.10). Children living in household with at least one parent who was obese were 6.51 times more likely to be in overweight or obese compared to those in household with both parents normal (OR = 6.51, 95%CI: 2.48 - 17.08). Overall, nationality and weight status of parents were the main determinants of children’s weight status. Promoting healthy diets and regular physical activity and educating parents on the consequences of overweight and obesity on children’s health in adulthood are effective strategies to control overweight and obesity.

What Is the Role of Work-Related Factors in Self-Reported Health Inequalities among Employed Individuals? A Longitudinal Study in Luxembourg

引用

Health 2018年第9期10卷 1141-1158页

作者： Anastase Tchicaya nathalie lorentz Kristell Leduc Living Conditions Department Luxembourg Institute of Socio-Economic Research (LISER) Esch-sur-Alzette Luxembourg

Objectives: We measured health inequalities among employed Luxembourg residents over time and the socio-economic and work-related determinants. Design and Setting: Longitudinal data were obtained from the Socio-economic Liewen zu Lëtzebuerg/European Union Survey on Income and Living Conditions, which has been conducted each year since 2003 in Luxembourg. Participants: Participants comprised 727 Luxembourg residents (58% men), aged between 21 and 55 years in 2003, who were employed between 2003 and 2012. Primary and Secondary Outcomes Measured: The variable of interest was self-reported health. We used transition indicators on work-related factors to consider changes that individuals may have experienced in their job over this period. Results: People who moved from a part-time to a full-time contract (odds ratio (OR): 5.52, confidence interval (CI): 1.55 - 19.73), and those who moved from the 3rd or 4th quartile of earnings to the 1st or 2nd quartile (OR: 2.48, CI: 1.02 - 6.05) between 2003 and 2012, had a higher risk of being in poor health in 2012. The risk of deterioration in self-reported health in 2012 among people who were healthy in 2003 was associated with the type of contract, economic activity, and occupation. Conclusion: Health inequalities occur among employed people in Luxembourg. Their importance varies according to work-related characteristics and economic activity. Our findings showed that declined health status was associated with contract type, profession, and economic activity. This suggests that measures should be taken to maintain good health for people working in these specific occupations or economic sectors (e.g. preventive action, reduction of risk exposure, change of occupation in the same company, and so on).

Analysis of mid-spatial frequency wavefront distortions from a liquid-cooled flash-lamp pumped Nd:phosphate laser amplifier

引用

High Power Laser Science and Engineering 2024年第1期12卷 24-29页

作者： Pierre-Marie Dalbies Sandy Cavaro Edouard Bordenave nathalie Blanchot Julien G.Moreau Jérôme Neauport CEA CESTA Le BarpFrance

Mid-spatial frequency wavefront deformation can be deleterious for the operation of high-energy laser systems. When fluid cooled high-repetition-rate amplifiers are used, the coolant flow is likely to induce such detrimental mid-spatial frequency wavefront deformations. Here, we describe the design and performance of a 90 mm × 90 mm aperture, liquid-cooled Nd:phosphate split-slab laser amplifier pumped by flash-lamps. The performance of the system is evaluated in terms of wavefront aberration and gain at repetition rates down to 1 shot per minute. The results show that this single cooled split-slab system exhibits low wavefront distortions in the medium to large period range, compatible with a focus on target, and despite the use of liquid coolant traversed by both pump and amplified wavelengths. This makes it a potential candidate for applications in large high-energy laser facilities.

Evaluation of the Reproduction Parameters of “Lohmann Brown” Strain Chickens Fed with Cajanus cajan Leaf Meal in the Republic of Congo

引用

Open Journal of Animal Sciences 2024年第3期14卷 234-248页

作者： Richard Missoko Mabeki Alexis Jonas Ognika Dora Chérita Ekou nathalie Myreille Ockoyi Parisse Akouango Laboratory of Animal Production and Biodiversity National School of Agronomy and Forestry Marien Ngouabi University Brazzaville Republic of the Congo Department of Animal Production and Health Marien Ngouabi University Brazzaville Republic of the Congo

The objective of this study was to evaluate the reproductive parameters of “Lohmann Brown” strain chickens fed on Cajanus cajan leaves and to assess the viability of the chicks after hatching. 40 hens of the “Lohmann Brown” strain fed on Cajanus cajan leaf flour laid 219 eggs divided into four batches depending on the rate of incorporation of Cajanus cajan leaf flour in the rations (0%, 5%, 10% and 15%) were trained and introduced into the incubator. Results: the incubator indicates a hatching temperature of 38˚C to 37.2˚C and relative humidity of 60% to 70%. Hatching performance shows that: The 15% batch recorded the highest fertility rate 86.95% compared to 26.88% of the control batch. The CC 15% batch recorded the highest hatching rate 36.87. The lowest rate (17.18%) was recorded in the control batch (CC 0%). The highest embryonic mortality rate was recorded in the CC 15% batch. The lowest rate in the CC 10% batch. Concerning unfertilized eggs, the highest rate is 72.20% (CC 0%), and the lowest are (12.03%;57.42% and 66.66%) recorded in CC batches. 15%, CC 5% and CC 10% respectively. For the shell mortality rate, the highest is 18.58% recorded in the CC 15% batch. The lowest shell mortality rate is 2.07%, obtained in the control batch (CC 0%);the dust mortality rate was 0% for all chicks. The study seems to indicate that the incorporation of Cajanus cajan leaf meal up to 15% into the reproduction type ration in hens does not cause any harmful effects on the reproduction performance of laying hens.

Froth flotation of scheelite – A review

引用

International Journal of Mining Science and Technology 2018年第3期28卷 373-384页

作者： nathalie Kupka Martin Rudolph Helmholtz Zentrum Dresden Rossendorf (HZDR) Helmholtz Institute Freiberg for Resource Technology (HIF)

Froth flotation of scheelite has regained new focus since the 2010s and research regarding floatability and reagents has made great progress over the years. The main objective was and remains the selective flotation of scheelite from other calcium-bearing minerals, in particular calcite, fluorite and apatite. Due to similar properties, most attempts have limited success or only specific application(linked to a type of ore or a location). This article aims at reviewing all general physical-chemical information on froth flotation of scheelite, including electrokinetic properties, influence of p H and already existing reagents as well as ones still under examination. It appears that chelating or mixed collectors and modified versions of sodium silicate and quebracho hold great promise for scheelite flotation, while the use of said depressants and/or promoters seems inevitable.
