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.

Risk Factors Associated with Unsuccessful Vaginal Birth after One Cesarean (VBAC-1) in Puerto Rico

引用

Open Journal of Obstetrics and Gynecology 2024年第6期14卷 888-902页

作者： Irazú Guinan Marjorie Suárez Fabiola Angulo Luis Mayol Paula Suárez Lisandris Dominicci nathalie Chang Saribel Torres Antonio Rodríguez Raymond L. Tremblay Maricarmen Colón-Díaz Department of Physiology and Pathology San Juan Bautista School of Medicine Caguas USA

Background: Cesarean section (CS) has increased steadily over the last decade, with an estimated one-third of women delivering by cesarean section worldwide. Objective: Our study aimed to investigate the demographic and associated factors influencing vaginal birth after one cesarean (VBAC-1) success focusing on variables like pre-pregnancy BMI, diabetes, hypertension, education, and smoking. Study Design and Methods: In this retrospective study, we analyzed 285 cases (81 unsuccessful VBAC-1, 204 successful VBAC-1) from San Juan City Hospital (Puerto Rico) between January 1, 2019, and December 31, 2020. We used odds ratios and model selection comparison to assess the impact of variables on successful VBAC-1, using a significance threshold of 95% CI. Model selection assessed binomial model combinations using a generalized linear approach to identify key risk factors. Results: Unsuccessful VBAC-1 (a repeat cesarean), was associated with diabetes (OR: 0.376, p = 0.086), hypertension (OR: 0.23, p = 0.006), and university-educated women (OR: 1.372, p = 0.711). High school-educated women had an OR of 3.966 (p = 0.105), while overweight women were 0.481 times more likely to have unsuccessful VBAC-1 (p = 0.041). Significant associations were not found with obesity (OR: 0.574, p = 0.122), underweight/normal (OR: 1.01, p = 0.810), or smoking (OR: 1.227, p = 0.990). Conclusion: Results revealed women with higher education levels, hypertension, or diabetes are less likely to have a successful VBAC-1. Understanding the complex interactions affecting these outcomes is aimed at establishing guidelines for healthcare professionals to conduct systematic risk/benefit assessments. This study lays a foundation for evidence-based practices and policies, offering initial insights into VBAC-1 success factors in Puerto Rico.
