Abstract

In this work, the effect of Forward Facing Steps (FFS) and Backward Facing Steps (BFS) on the Hybrid Rocket Engine’s regression rate is investigated through test firings on both a classic cylindrical motor and a two-dimensional slab burner with optical access. It serves as a first experimental investigation into the proposal to distribute a set of steps along any predefined fuel port profile. For the cylindrical motor, asingle FFS or BFS increased the total average regression rate by up to 48 % and 53 % respectively. On the slab burner, the local zones of high regression rate could be directly derived from the optical access during the burn and they correlate precisely to the regression rate profiles of the cylindrical cases., info:eu-repo/semantics/published

Abstract

Multiple human papillomavirus (HPV) genotypes often co-exist within the cervical epithelium and are frequently detected in smears of different grades of cervical neoplasia. Describing the association of multiple infections with cervical disease is important to generate hypotheses regarding its pathogenesis. We analyzed the prevalence of multiple HPV infections and their attribution to cervical disease in a screening population of 999 consecutive BD-SurePath liquid-based cervical cytology samples enriched with additional ASC-US (n=100), LSIL (n=100) and HSIL (n=97). HPV genotyping was performed on cytology specimens only using BSGP5+/6+-PCR/MPG that detects and quantifies 51 HPV genotypes and 3 subtypes. Using a recently defined high viral load cutoff, the quantitative data was scored as high or low viral load. In the 36 month follow-up, 79 histologically confirmed CIN2+ cases were identified. In the screening population, there was a trend of having more multiple infections at a younger age. Multiple HPV infections were common. Multiple HPV types were most prevalent in LSIL (75.9% of HPV positives), followed by HSIL (65.5%), ASC-US (64.6%) and NIL/M (36.8%). In average, 3.2 and 2.5 HPV types were detected per LSIL and HSIL sample, respectively. Multiple HPV types with high viral loads were most prevalent in LSIL (62.6% of high viral load positives), followed by HSIL (51.9%), ASC-US (40.7%) and NIL/M (19.3%). Patients with multiple high viral loads showed a 4- to 6-fold increased risk of having cervical precancerous cytological lesions than patients with single high viral loads. Compared to NIL/M, multiple infections, especially with multiple high viral loads, were significantly associated with cytological precancerous lesions. However, the presence of multiple infection did not distinguish low-grade from high-grade cytological lesions.

Abstract

He was graduate pharmacist at the "Ecole de pharmacie de Montpellier" in 1826. At the same time his report about a new element was read to the members of Academy of Sciences in Paris. He has found bromium in the waters from Mediterranean salt-marsh. This discovery was the starting point of a new chemistry. It was indeed the first time that someone demonstrated the existence of chemical elements families.

Abstract

Antoine-Jérôme Balard, who was the discoverer of bromium, had a private life impressed of large success but also of many difficult events. From the beginning to the end of his life (1802-1876) he showed often unexpected behaviors, always with large originality, simplicity and generosity.

Abstract

Please cite this paper as: Simoens C, Goffin F, Simon P, Barlow P, Antoine J, Foidart J, Arbyn M. Adverse obstetrical outcomes after treatment of precancerous cervical lesions: a Belgian multicentre study. BJOG 2012;119:1247-1255. Objective To assess the impact of cervical intraepithelial neoplasia (CIN) treatment on the risk of (spontaneous) preterm delivery (PD) and small for gestational age (SGA) at birth. Design A multicentre cohort study. Setting Maternity wards of four academic hospitals in Belgium. Population Ninety-seven exposed pregnant women (with a CIN treatment history) and 194 nonexposed pregnant women (without a history of CIN treatment). Methods A questionnaire and check of obstetrical files included socio-demographic characteristics, risk factors for PD, obstetrical history for all women and characteristics of the CIN treatment for exposed women. Pregnancy outcomes were recorded after delivery. The influence of previous treatment of CIN on pregnancy outcomes, adjusted for confounding variables, was assessed by Cox regression and lifetables (for the outcome gestational age at birth) and by logistic regression (for the outcomes PD and SGA at birth). Main outcome measures Occurrence of PD and SGA at birth. Results Seventy-nine per cent of the women in the database were multiparous; 16.3% of women with a previous excisional treatment spontaneously delivered preterm, compared with 8.1% of unexposed women [odds ratio (OR), 2.19; 95% confidence interval (CI), 0.97-4.99]. When adjusting for confounding factors (ethnicity, HIV status, education, age, smoking and parity), the OR for PD was 2.33 (95% CI, 0.99-5.49). Excisional treatment did not have an impact on SGA at birth (OR, 0.94; 95% CI,0.41-2.15). The depth of the cone was >10 mm in 63.5% of the documented cases. Large cones, more than 10 mm deep, were associated with a significantly increased risk of PD (adjusted OR, 4.55; 95% CI, 1.32-15.65) compared with untreated women, whereas smaller cones (≤10 mm), SCOPUS: ar.j, FLWIN, info:eu-repo/semantics/published
