The significance of tumor spill in the early stages of ovarian carcinoma has been the subject of controversy. Since rupture of the capsule of the tumor may occur in several different ways, we analyzed all cases of early ovarian cancer treated at Radiumhemmet, Stockholm, Sweden, during the period 1974–1986, in which possible spill of tumor cells was catalogued in different groups. In 247 out of 394 patients (62%) the risk of spill had to be considered. There was no difference in survival between patients whose tumors had intact capsules and patients in whom rupture occurred during surgery—78% and 85%, respectively. On the other hand, a significant difference in survival was found between patients in whom rupture occurred before surgery and those with intraoperative rupture—59% and 85%, respectively. The conclusion can be drawn that manipulation during surgery which results in puncture or rupture does not have a negative influence on the outcome for the patients.

This work presents a comparison of two inocula used for the acclimation of two anaerobic-aerobic sequencing batch bioreactors used for toxic wastewater treatment. The bioreactors were acclimated with different types of sludge: one coming from an anaerobic wastewater treatment plant and the other one from a conventional aerobic activated sludge plant. The model toxic compound was p-nitrophenol, which is reduced to p-aminophenol during the initial anaerobic phase of the reaction, and later mineralized during a posterior aerated reaction phase. Biodegradation of the compounds was monitored using UV/Vis spectrophotometry. After acclimation stabilization of the sludge and of the process was also monitored. Results show that there is no significant difference in acclimation times and stability of the process between the two employed inocula, and thus an originally anaerobic inoculum presents no apparent advantage over a more easily accessible aerobic one.

Abstract The decline in groundwater availability and quality has become a worldwide issue and has been the subject of several studies in recent decades. In this sense, the goal of this study is to assess the vulnerability of the Campeche Aquifer (Florianopolis, Brazil), identifying potential areas of possible contamination by the direct infiltration of runoff in drainage compensatory techniques. To achieve this goal, the following methodological steps were used: (1) data collection and preparation, (2) application of the DRASTIC model, (3) sensitivity analysis and (4) analysis of potential contamination by compensatory techniques. The results show that approximately 33% of the aquifer area presented moderate vulnerability to contamination. However, 29% of the remaining areas had high and extremely high vulnerability. Analysing the potential of contamination with drainage compensatory structures we verified that approximately 95% of them are located in areas of vulnerability classified as moderate and high. The other 5% were identified in areas with extremely high vulnerability. Sensitivity analyses indicated that the removal of topography, soil type and the impact of the vadose zone caused a large variation in vulnerability index. It is evident that there is a high potential of contamination of groundwater by direct infiltration of drainage compensatory structures.

Course Of Study

Introduction: This study examines the influence of major fluctuations in the number of students enrolling at university on the probability of dropout or a switch to a different course of study. Findings from the US show that a pronounced increase in student numbers leads to more dropouts. Materials and methods: This article provides an analysis of this relationship for the first time outside the US and for an entire university system. We use administrative data for all the students who started studying at Swiss universities between 1980 and 2001. Results: The results suggest a significant relationship between positive cohort growth and the probability of dropout. A reduction in student numbers, on the other hand, does not increase the probability of persistence. Discussion: Despite the negative influence of a big cohort on the probability of persistence, no statistically significant relationship exists, by contrast, between the change in student numbers and the probability of a student switching to a different course of study.

The subject of this paper is improvement in the growth and yield of three different types of legumes and rape in drought conditions by coating seeds with hydrolysed collagen from tanning waste. In addition, the impact of various additives in the seed shell on the growth of the plant was investigated. The encapsulation process of seeds was conducted on a disc granulator. A centrally placed seed was first coated with a layer of fungicides. The next layer was collagen hydrolysate, collagen hydrolysate with latex or a solution of yellow dextrin and polyvinyl alcohol. The outer layer was a mineral additive e.g. dolomite or kaolin. After the end of the encapsulation process on the disk granulator, all of the seeds tested were sown into soils. Seeds without coating were also sown as control seeds. Seedlings were maintained for 29 days with cultivation without irrigation. The length of the seedlings was analysed for all of the seeds sown. Higher seedling growth values were obtained for seeds coated with collagen hydrolysate in comparison with control seeds (without coating). The use of collagen hydrolysate gave slightly better results than in the case of a solution of dextrin with polyvinyl alcohol.

The cabin of an inflight aircraft contains approximately 10% relative humidity (rh). To investigate the impact of this environment on eye comfort, an inflight humidity profile was simulated in a controlled laboratory setting. The experiment was replicated 3 times using a group of 4 subjects (2 males; 2 females) per test. Participants served in both control and experimental roles by wearing a hydrophilic contact lens on one eye and no lens on the other. Subjects provided evaluations of “eye comfort” for both eyes (contact and naked) at specified intervals during the 10 hour test. The results indicated that at 10% rh, there was no significant difference in eye comfort for either wearers or nonwearers of soft contact lenses. However, comfort decreased with the length of exposure (flight time), and for durations of six hours or longer a significant annoyance was reported.

Abstract Background: A retrospectively cohort study was performed to compare the birth weight of different blastocyst grades in fresh transplantation cycle and explore the related factors affecting the birth weight. Methods: The 1301 fresh cycles of single blastocyst transplantation and single live birth profile were analyzed,four groups were divided according to the grade of transplanted blastocyst. There are 170 cycles in group A with AA blastocyst grade, 312 cycles in group B with AB/BA blastocyst grade, 559 cycles in group C with BB/CA/AC blastocyst grade and 260 cycles in group D with BC/CB blastocyst grade. Comparison were made among four groups of birth weight, general conditions, fertilization rate, embryo rate, cleavage rate and D5,D6 blastocyst formation rate and other laboratory indicators. And then comparison were performed among the birth weight of different groups which were divided by the degree of blastocyst expansion, and the classification of inner cell mass(ICM) and the trophectoderm(TE). Results: The study shows that the birth weight of group A is significantly higher than that of the other three groups (P < 0.05). And the high quality embryo rate and blastocyst rate of group A are significantly higher than those of the other three groups (P < 0.05). What’s more, the clinical pregnancy rate, implantation rate and live birth rate of high grade blastocyst are higher, but there are no significant difference in abortion rate. The birth weight of the degree of blastocyst expansion in grade 3 and below is significantly lower than that of those with grade 3 and above (P < 0.05). The birth weight of grade A of ICM is significantly higher than that of grade B (P < 0.05). The birth weight of grade B of TE is significantly heavier than that of grade C (P < 0.05). Conclusions: Our results indicate that high grade blastocyst transplantation can achieve better pregnancy outcome. Different blastocyst grades affect birth weight, and low grade blastocyst transplantation is associated with a single birth weight loss.

The aim of this study was to assess the impact of the leptin concentration and body weight of mink females on the birth parameters of their kits. Blood samples were collected 3 times during preparation for reproduction, 7±2 days before mating. Total leptin concentration in serum was measured using commercial RIA kits (Millipore, St. Charles, Missouri USA). Research was conducted on 20 clinically healthy scanbrown female minks (Neovison Vison) aged 2-3 years. To evaluate their body condition, the females were divided into two groups based on the BCS scoring system. In the first group, referred to as BCS 2, lean females were included, and the second group (BCS 4) consisted of obese females. In mink dams belonging to BCS 2, the average leptin values were one-fourth of those in the BCS 4 group. The results obtained indicate the influence of the body mass of minks during preparation for reproduction on serum leptin concentration. The results of the Mann-Whitney U test showed a statistically significant difference between weights and leptin concentrations in groups BCS 2 and BCS 4. Among the other traits, such differences were not found. The analysis of results obtained in the two mink groups did not reveal a clear relationship between leptin in the serum of mothers before mating and the birth parameters of their kits.

Ongoing global COVID-19 pandemic is not only health crisis but the economic challenge. The future of society depends on how successfully the authorities find a balance between imposition of stringent restrictions and economic development. Tax policies play a role in reducing losses caused by the COVID-19 lockdowns. All countries are taking tax measures to mitigate the impact of the effects of COVID-19 pandemic on society. While the COVID-19 pandemic has not yet been defeated, it is too early to draw conclusions about which tax measures against the effects of COVID-19 are efficient. On the other hand, correct trajectory of economic recovery can be missed if not to analyze the other countries experience. The object of this study is tax measures in the European countries against the effects of COVID-19. The subject of the study is the fuzzy set theory to assess the efficiency of tax measures in the European countries against the effects of COVID-19. The aim of the study is to find out which European countries have been more succeeded in tax measures implementing and type of their immediate crisis response. The analysis is carried out in 29 European countries. The result of the study allows to state that the number of tax measures against the effects of COVID-19 does not affect their efficiency and the most popular type of immediate crisis response has been the business cash-flow enhances.
