Contribution à la compréhension des phénomènes de transfert de solutés en nanofiltration : caractérisation des membranes et application aux composés toxiques

La recherche sur la nanofiltration a permis de determiner les conditions de caracterisation des membranes par porometrie bi-liquide et par mesure du potentiel d'ecoulement. La limite de la methode porometrique a ete definie a 2 nm et la mesure du potentiel d'ecoulement permet de determiner le point iso-electrique et la charge de la membrane. Des essais experimentaux sur une unite de laboratoire sont effectues en utilisant des composes ioniques (nacl, na#2so#4, cdcl#2 et cdso#4) et des solutes toxiques neutres (phenol, atrazine). Les resultats obtenus dans differentes conditions operatoires (ph, concentration,. . ) sont relies aux caracteristiques des trois membranes etudiees (nf45, opmn-k et opmn-km). Les retentions des differents solutes sont analyses et les mecanismes de transfert preponderants en nanofiltration sont definis : l'importance des sites anioniques et cationiques de la membrane est mis en evidence dans la separation des solutes ioniques. Les resultats obtenus montrent d'autre part que la nanofiltration est un procede envisageable pour epurer les effluents contenant des solutes toxiques ioniques ou non ioniques de faibles masse moleculaire.
Aorto-mitral curtain reconstruction in invasive double-valve endocarditis: mid-term outcomes

Background Invasive double-valve endocarditis with structural damage (abscess or perforation) of the aorto-mitral curtain is a relatively rare but fatal diagnosis requiring complex surgical reconstruction. This study presents the short-term and mid-term outcomes from a single center. Methods From 2014 to 2021, 20 patients with double-valve endocarditis with structural damage of the aorto-mitral curtain underwent surgical reconstruction (Hemi-Commando procedure n = 16 and Commando procedure n = 4). Data were obtained retrospectively. Results In 13 cases, the procedure was a reoperation. The mean cardiopulmonary bypass time was 239 ± 47 min and the mean cross-clamp time was 186 ± 32 min. Concomitant procedures were tricuspid valve repair in two, coronary revascularization in one, closure of a ventricular septal defect in one and hemiarch (using circulatory arrest) in one patient. Eleven patients (55%) required surgical revision for bleeding. Thirty-day mortality was 30% (6 patients)—3 patients from the Hemi-Commando group (19%) and 3 patients from the Commando group (75%). Overall survival at 1, 3 and 5 years was 60%, 50% and 45% respectively. Reoperation was required by 4 patients. Freedom from reoperation at 1, 3 and 5 years was 86%, 71% and 71% respectively. Conclusion Despite the high postoperative morbidity and mortality, complex surgical reconstruction of the aorto-mitral continuity of patients with double-valve endocarditis represents the only real chance for survival. Mid-term outcomes are acceptable, but strict follow-up is required due to the risk of valve failure.
Ni2P-MoS2/γ-Al2O3 Catalyst for Deep Hydrodesulfurization viathe Hydrogenation Reaction Pathway

A series of highly active Ni2P-MoS2/γ-Al2O3 catalysts were prepared and characterized, the catalytic performanceof which was evaluated through hydrodesulfurization of dibenzothiophene. The result indicated that when the amount ofNi2P was 4%, the catalyst showed a relatively high activity to provide a reliable reference for the hydrodesulfurization pathwayin comparison with the conventional NiMo and NiMoP catalysts. The physicochemical properties of the catalysts werecorrelated with their catalytic activity and selectivity on hydrodesulfurization. The stacking number of active MoS2 phaseswas important for influencing the hydrogenation activity.
SKŁAD KWASÓW TŁUSZCZOWYCH TŁUSZCZU MLEKA KRÓW Z CHOWU ALKIERZOWEGO W OKRESIE LETNIM I ZIMOWYM

S t r e s z c z e n i e Sklad i jakośc mleka zalezą od roznych czynnikow, m.in. uwarunkowan genetycznych, środowiskowych, stanu fizjologicznego zwierząt oraz pory roku. Wplyw pory roku uwidocznia sie sezonowością w produkcji mleka (sezon zimowy – zywienie oborowe; sezon letni - zywienie pastwiskowe). Jednak w ostatnich latach zmieniają sie warunki chowu bydla mlecznego, ktore polegają na przechodzeniu na caloroczne alkierzowe utrzymanie krow, w ktorym zywienie pastwiskowe zastąpione jest systemem PMR. Moze to sie wiązac ze zmianą skladu mleka, w tym profilu kwasow tluszczowych. W celu zweryfikowania tej hipotezy, podjeto badania mające na celu analize tluszczu mleka z sezonu letniego oraz zimowego, pobranego z duzego gospodarstwa rolnego stosującego zywienie systemem PMR. Tluszcz z mleka ekstrahowano metodą Rosego-Gottlieba, zaś estry metylowe kwasow tluszczowych w wyodrebnionym tluszczu przygotowano wedlug metody IDF Standard. Rozdzial estrow metylowych wykonano metodą chromatografii gazowej, stosując chromatograf gazowy wyposazony w detektor plomieniowo-jonizacyjny (FID). Stwierdzono, ze w okresie letnim tluszcz pozyskanego mleka zawieral wiecej nienasyconych, a w okresie zimowym – wiecej nasyconych kwasow tluszczowych. Roznice te spowodowane byly przede wszystkim wzrostem zawartości kwasu oleinowego, stearynowego oraz wielonienasyconych kwasow tluszczowych, a takze zmniejszeniem zawartości kwasow palmitynowego, mirystynowego i laurynowego w okresie letnim. Ponadto wykazano, ze pomimo zastosowania alkierzowego sposobu utrzymaniu krow, w profilu kwasow tluszczowych nadal wystepują zmiany, ktore są charakterystyczne dla sezonu letniego oraz zimowego.

Plasma Lactate Accumulation During Running with Body Weight Unloading by LBPP

Plasma Lactate Accumulation During Running with Body Weight Unloading by LBPP Nicole Nevitt Rasmussen Department of Exercise Sciences, BYU Master of Science At any given running speed, weight support with a lower body positive pressure (LBPP) device (i.e. Alter-G treadmill) reduces VO2. However, it is unknown how application of LBPP during running impacts lactate metabolism, specifically lactate threshold. Purpose: To determine if body weight unloading with the Alter-G treadmill alters lactate threshold. Methods. Maximal aerobic capacity (VO2max) and lactate threshold (LT) was determined in 8 male subjects on an Alter-G treadmill at 100% and 80% body weight loading at 0% grade in a randomized crossover design. VO2max tests started at 7 mile h and increase speed by 1 mile h every 2 min till voluntary exhaustion and were separated by a minimum of 7 days. LT tests started at 5 mile h and increased speed to 6, 7, 7.5, 8.0, 8.5, 9.0 (additional stages increase speed by 0.5 mile h) every 3 min until the subject reached ≈85% of VO2max. LT tests were separated by a minimum 3 days. VO2, heart rate (HR), mean arterial blood pressure (MAP) and changes in Hct, [Hb], and total protein ([TP]) were determined on separate days in a randomized crossover design. Plasma lactate concentrations were determined from venous blood samples (4 ml) obtained at rest and during the last minute of each exercise stage. Lactate threshold was determined from a log-log plot of lactate concentration (mM) and relative VO2 (ml O2 min kg BM). Results. VO2max determined during running at 100% and 80% loading were similar (52.3 ± 0.9 and 52.7 ± 0.7 ml O2 min kg BM, respectively). The energy cost of running at 9 mile h (all subjects completed stages between 5 and 9 mile h) was reduced by 12% at 80% body weight (37.2 ± 2.9 ml O2 min 1 kg BM) compared to running at 100% body weight (42.3 ± 1.7 ml O2 min kg BM, p<0.05). However, plasma lactate at 9 mile h was similar during 80% and 100% body weight running (3.4 ± 0.4 and 3.1 ± 0.7 mM, respectively). Plasma lactate at a given VO2 was higher (p < 0.05) while running at 80% body weight compared to 100% body weight running. Calculated LT at 100% BW loading (36.3 ± 1.3 ml O2 min kg BM) was higher than 80% BW loading (32.2 ± 1.8 ml O2 min kg BM, p<0.05). During running at 80% BW HR was reduced compared to 100% BW running (p<0.05) however the MAP response was similar. During exercise the reduction in PV, at any given VO2 was larger at 80% BW compared to 100% BW running (p<0.001). Conclusion. During running, BW unloading with LBPP decreased the energy cost of exercise but not lactate levels. Body weight unloading caused a lowering of the LT. The reduction in whole body energy cost was not associated with a reduction in the lactate production since plasma lactate accumulation at a given speed was similar with and without LBPP.

Combination of Spaceborne, Airborne and In-Situ Gravity Measurements in Support of Arctic Sea Ice Thickness Mapping

This report is a quantitative study of gravity field and geoid, mean sea surface, mean ocean dynamic topography and tides for the Arctic Ocean, for a large range of existing and new models. The report gives quantitative assessments of errors and error covariances of the different fields, mainly for use of understanding total errors in the mean sea surface (MSS). The error studies are especially directed towards the CryoSat sea-ice freeboard processor, where the MSS is the basic reference surface, especially in order to quantify if this processor will benefit from adaptive “smart” interpolation, where the varying error covariances of the MSS are taken into account. As part of the studies a new Arctic gravity field model and geoid has been derived, based on all available terrestrial and airborne gravity data and GRACE satellite data, augmented with gravity field information from ICESat. Rigorous error and covariance of studies of the computed geoid model have been done, showing that the new Arctic geoid is accurate to better than 10 cm over most of the region. Mean dynamic ocean topography is estimated from remote sensing by combining ERS and ICESat altimetry with the geoid, and compared to four different oceanographic models. The comparison shows large differences between the different oceanographic models, and a reasonable agreement to the results from remote sensing. This part of the study illustrates the potential of future radar altimetry missions such as Cryosat for determining ocean dynamic topography and its temporal changes, in addition to the sea ice freeboard heights. A number of tidal models are intercompared, and compared to tide gauge data in the Canadian Arctic. The presence of sea-ice is found to damp the tidal amplitudes and it appears that tidal errors will be a major regionally-dependent error source in sea surface determination for CryoSat. The error covariances and model comparisons are used in a “smart” adaptive estimator scheme, where a linear interpolator operator, similar to the future CryoSat freeboard estimator, is used to quantify errors of the interpolator. Some suggestions for utilization of GOCE data are included in the report, as well as recommendations and a future outlook. The work described in this report was done under ESA Contract.

Effect of Heat Treatment on the Antioxidant Properties of Tetrapleura Tetraptera, Xylopia Ethiopica and Piper Guineense

Phytoscreening and the effect of heat treatment on the antioxidant activity were studied in three medicinal plant parts used mostly by nursing mothers in Southern Nigeria;Tetrapleura tetraptera, Piper guineense and Xylopia ethiopica. Total Phenols, Flavonoids and Vitamin C content of these spices were determined at different heating periods (0, 30,60, and 90mins) at 100 o C and the results showed significant Phenol acumulation in tubers (1554. 54mgkg −1 , 1555. 01 mgkg −1 , and 1550. 04 mgkg −1 DW) for T. tetraptera, P. guineense and X. ethiopicarespectively at zero heat treatment. The antioxidant activity was determined by ferric ion reducing/ antioxidant power (FRAP) assay. Results indicate a significant increases (p ≤ 0.05) in FRAP vaalues of T. Tetraptera aqueous extracts at all monitored times.Similar trend was observed in heat - response for flavonoid content of measured spices. Increase in heat treatment time gave statistically significant decreases in observed levels of Vitamin C for all spices studied These suggest that heat treatment could have beneficial effect by improving antioxidant activity in consumers of these spices but prolonged treatment could have an inhibitory effect.The results recorded clearly indicate Vitamin C and total Phenolic content loss due to thermal treatment. Also, high antioxidant properties expressed by T. Tetraptera expresses a potential to inhibit possible oxidation of LDL cholesterol.

Vida Pessoal e Vida Profissional: os Desafios de Equilíbrio para Mulheres Empreendedoras do Rio de Janeiro

This study analyzes the issues related to work-life balance of two different groups of women entrepreneurs. Data was collected through twenty in-depth interviews, ten conducted with women in the daycare business and ten conducted with women in the catering business. All of these women work on the south side of Rio de Janeiro and their clients are upper middle class. Women consider flexibility in their time schedules to be the most important point in balancing the demands of work and family. Although they are constantly worried about their achievements, personal support from their husbands, family members and business partners helps keep the balance. The study also suggests that characteristics that are business specific intervene in this balance and must, therefore, be considered in this type of study
Relationship between leaf nutrient concentration and the yield of fibre hemp (Cannabis sativa L.).

This study was conducted to determine the optimum time for plant analysis, which can provide useful indications of nutrient deficiencies in plants, and to establish limit values for nutrient supplies to fibre hemp (Cannabis sativa L.). The effect of nutrient supplies on the nutritional status of fibre hemp was estimated by leaf analysis in a long-term field fertilisation experiment at four NPK levels on chernozem meadow soil in Szarvas, Hungary in 1999 (good water supplies) and 2003 (dry). The optimum time for the diagnostic analysis of fibre hemp was found to be late May or early June, when plants in the 5–7-leaf stage are 70–100 cm in height, with a biomass of 2–5 t ha dry matter, depending on water and nutrient supplies, variety and production condition. Nutrient supplies to hemp can be considered satisfactory if plant analysis reveals 5–6 % N, 0.5–0.6 % P and 2.7–3.3 % K in the youngest fully developed leaves in late May. A stem yield (10 % moisture content) of 12– 17 t ha was achieved when rainfall supplies were adequate (1999), while in the dry year (2003) the lower nutrient concentrations in the uppermost leaves, indicating nutrient deficiency, resulted in a maximum stem yield of only 6–8 t ha. The low, satisfactory and high values for the concentrations of N, P, K, Ca, Mg, Fe, Mn, Zn and Cu reported in the paper could be used to elaborate a fertiliser recommendation system for hemp.
The Knobe effect: A brief overview.

Joshua Knobe (2003a) has discovered that the perceived goodness or badness of side effects of actions influences people's ascriptions of intentionality to those side effects. I present the paradigmatic cases that elicit what has been called the Knobe effect and offer some explanations of the Knobe effect. I put these explanations into two broad groups. One explains the Knobe effect by referring to our concept of intentional action. The other explains the Knobe effect without referring to our concept of intentional action. I discuss some problems with these explanations and conclude with some possible avenues for future research.
Lymphedema after gynecological cancer treatment: Prevalence, correlates, and supportive care needs

BACKGROUND: Few studies have evaluated lymphedema following gynecological cancer. The aim of this research was to establish the prevalence, correlates and supportive care needs of gynecological cancer survivors who develop lymphedema. ----- METHODS: In 2004, a population-based cross-sectional mail survey (56% response rate) was completed by 802 gynecological cancer survivors. The questionnaire included demographic questions, a validated, generic supportive care needs measure, and a supplementary, newly-developed, lymphedema needs module. ----- RESULTS: Ten percent (95% CI: 8-12%) of participants reported being diagnosed with lymphedema and a further 15% (95% CI: 13-17%) reported undiagnosed ‘symptomatic’ lower limb swelling. Diagnosed lymphedema was more prevalent (36%) amongst vulvar cancer survivors. For cervical cancer survivors, those who had radiotherapy or who had lymph nodes removed had higher odds of developing swelling. For uterine and ovarian cancer survivors, those who had lymph nodes removed or who were overweight or obese had higher odds of developing swelling. Gynecological cancer survivors with lymphedema had higher supportive care needs in the information and symptom management domains compared to those with no swelling. ----- CONCLUSIONS: This population-based study provides evidence that lymphedema is a morbidity experienced by a significant proportion of gynecological cancer survivors and that there are considerable levels of associated unmet need. Women at risk of lymphedema would benefit from instructions about early signs and symptoms and provision of referral information.
