Non universality of entanglement convertibility

Recently, it has been suggested that operational properties connected to quantum computation can be alternative indicators of quantum phase transitions. In this work we systematically study these operational properties in 1D systems that present phase transitions of different orders. For this purpose, we evaluate the local convertibility between bipartite ground states. Our results suggest that the operational properties, related to non-analyticities of the entanglement spectrum, are good detectors of explicit symmetries of the model, but not necessarily of phase transitions. We also show that thermodynamically equivalent phases, such as Luttinger liquids, may display different convertibility properties depending on the underlying microscopic model.Comment: 5 pages + references, 4 figures - improved versio

Identification of sources of seedling resistance to Phytophthora capsici in Cucumis melo

The employment of genetic resistance to minimize yield losses induced by Phytophthora capsici remains unexplored in melon (Cucumis melo). A diverse collection of melon accessions was evaluated against P. capsici isolates at the seedling stage. In the frst screening assay, 105 accessions were evaluated using isolate PCpe-04 obtained from cucumber (Cucumis sativus). In a second assay, 31 accessions displaying high levels of resistance in the frst assay were challenged with a distinct isolate (PCpe-09 also from cucumber). In a third assay, a subset of 14 selected accessions was re-evaluated using isolates PCpe-09 and PCmo-07 (from strawberry). In the last screening, seven accessions with high levels of resistance across all assays were challenged with fve isolates from representative host species [PC-Vagem (snap bean), PCp-129 (Capsicum chinense), PCp-155 (C. annuum), PCpe-09 and PCmo-07] to assess their reaction against a varied sample of P. capsici isolates. For two accessions (CNPH-093 and L040), all plants remained free of symptoms after inoculation with all fve isolates. Accessions WMR-29, CNPH 084, CNPH 088 and CNPH 092 were also free of symptoms to all isolates, except PCmo-07. These large-spectrum resistance sources might be useful for breeding programs aiming to incorporate resistance against P. capsici in elite melon lines

Characterization of Fuji Apples from Different Harvest Dates and Storage Conditions from Measurements of Volatiles by Gas Chromatography and Electronic Nose

Volatile compounds in Fuji apples harvested at two different maturities were measured at harvest and after 5 and 7 months of cold storage (1 °C) in four different atmospheres. When the samples were characterized by both chromatographic measurements of volatiles and responses of an electronic nose, the analyses showed a clear separation between fruits from different storage conditions (a normal cold atmosphere and three controlled atmospheres). During poststorage, the apples were left to ripen for 1, 5, and 10 days at 20 °C before analytical measurements were done involving headspace-gas chromatography methods and electronic nose type quartz crystal microbalances. Electronic nose responses registered by seven different sensors were used to classify the apples using principal component analysis. It was possible to identify the samples from different storage periods, days of shelf life, and harvest dates, but it was not possible to differentiate the fruits corresponding to different cold storage atmospheres

Family Health Strategy and More Doctors Program in Rural Area of Porto Velho, Brazil: A Qualitative Analysis under the Nurse’s Perspective

The Family Health Strategy (FHS) together with the implementation of the More Doctors Program (MDP) has an effective contribution to the strengthening of Primary Health Care (PHC) and the consolidation of the Unified Health System (SUS), which has intended to meet the health needs of the population in need of care less complex. Thus, this study aims to analyze the Family Health Strategy and the Program More Doctors implanted in the Rural Municipality of Porto Velho, Rondônia, from the perspective of nurses. This is a qualitative research, descriptive exploratory performed in the field, based on the assessment the perspective of nurses working in the FHS, which are favored by the MDP. The data collection was carried out through a questionnaire,Primary Care Assessment Tool (PCA Tool), in its version validated in Brazil entitled PCA Tool- Brazil (BRAZIL, 2010). This instrument is widely used by national research that evaluates the quality of primary care. For the construction of the database was used Microsoft Word software. For qualitative data, the collection was carried out through interviews recorded by a script containing open questions. The response were discussed based on the content analysis technique proposed by Bardin (2011). The results achieved indicate that the MDM enabled the structuring of teams that were incomplete in the rural area of the town, however presents numerous challenges in the organization of the work process and the understanding of program objectives

Rarity of monodominance in hyperdiverse Amazonian forests.

Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tree Diversity Network (ATDN). Utilizing a simple defining metric of at least half of the trees ≥ 10 cm diameter belonging to one species, we found only a few occurrences of monodominance in Amazonia, and the phenomenon was not significantly linked to previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation of sprouts at the base of the tree or on roots) was the only trait significantly linked to monodominance. While at specific locales coppicing or ectomycorrhizal associations may confer a considerable advantage to a tree species and lead to its monodominance, very few species have these traits. Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors

Analgesic efficacy of Lysine Clonixinate, paracetamol and dipyrone in lower third molar extraction. A randomized controlled trial

Objective: The purpose of this study is to compare the analgesic effect of lysine clonixinate, paracetamol and dipyrone after lower third molar extraction.Material and Methods: The sample consisted of 90 individuals, with clinical indication for inferior third molars extraction. The mean age of the sample was 22.3 years (DP±2.5). The individuals received the medication in unidentified bottles along with the intake instructions. The postoperative pain parameters were measured according to Visual Analogical Scale (VAS) and the data was evaluated using the Kruskal-Wallis Test and Friedman Test, with the latter used to test different time intervals for each one of the drugs.Results: The final sample consisted of 64 individuals, including 23 males (45.9%) and 41 females (64.1%) The mean age of the entire sample was 22.3 years (±2.5). The average length of the procedures was 33.9 minutes (±9.8).The distribution of mean values for this variable showed little variance for the different drugs (p=0.07).Conclusion: Lysine Clonixinate did not show any substantial impact on the postoperative pain control when compared to other drugs

Retornos e riscos na comercialização de milho no Estado do Paraná: uma aplicação do modelo value-at-risk

This paper aimed to evaluate risk and returns of marketing strategies adopted by farmers, cooperatives and grain elevators in the State of Paraná, Brazil, using data for the period 1994-2001. For farmers, the only strategy analyzed was storage, while for coops and grain elevators three strategies were considered: storage (EST), short selling (VD) and buying and selling simultaneously (CVS). The risk analyses were carried out by means of Value-at-Risk (VaR) models using three approaches: Normal Delta, Historical Simulation and Monte Cario Simulation. The returns were weighted with a modified version of the Sharpe Index (/5 ), generating an index of probabilistic returns. In the period analyzed, storage was not viable for farmers'as well as for grain elevators. The VD strategy was profitable without taking risk into consideration. CVS is the best strategy when only strategies with ASj, larger than one are considered profitable

Periodontal treatment during pregnancy decreases the rate of adverse pregnancy outcome: a controlled clinical trial

OBJECTIVES: The aim of this study was to evaluate the effects of non-surgical treatment of periodontal disease during the second trimester of gestation on adverse pregnancy outcomes. MATERIAL AND METHODS: Pregnant patients during the 1st and 2nd trimesters at antenatal care in a Public Health Center were divided into 2 groups: NIG - "no intervention" (n=17) or IG- "intervention" (n=16). IG patients were submitted to a non-surgical periodontal treatment performed by a single periodontist consisting of scaling and root planning (SRP), professional prophylaxis (PROPH) and oral hygiene instruction (OHI). NIG received PROPH and OHI during pregnancy and were referred for treatment after delivery. Periodontal evaluation was performed by a single trained examiner, blinded to periodontal treatment, according to probing depth (PD), clinical attachment level (CAL), plaque index (PI) and sulcular bleeding index (SBI) at baseline and 35 gestational weeks-28 days post-partum. Primary adverse pregnancy outcomes were preterm birth

Factors associated with the prescription of vaginal pessaries for pelvic organ prolapse

OBJECTIVE: To identify the factors associated with the prescription of vaginal pessaries (VPs) as a conservative treatment for pelvic organ prolapse (POP). METHODS: A cross-sectional study was performed during two annual urogynecology and general obstetrics and gynecology meetings in 2017 (Sa˜o Paulo, SP, Brazil). A 19-item deidentified questionnaire regarding experiences and practices in prescribing VPs for POP patients was distributed among gynecologists. Our primary outcome was the frequency of prescribing VPs as a conservative treatment for POP. The reasons for prescribing or not prescribing VPs were also investigated. Univariate and multivariate analyses with crude and adjusted odds ratios (ORs) were performed for variables associated with the prescription of pessaries. RESULTS: Three hundred forty completed surveys were analyzed. Half of the respondents (53.53%) were between 30-49 years old; most of them were female (73.53%), were from the Southeast Region (64.12%), were trained in obstetrics and gynecology (80.24%) or urogynecology (61.18%) and worked in private offices (63.42%). More than one-third (36.48%) attended four or more POP cases/week, and 97.65% (n=332) had heard or knew about VPs for POP; however, only 47.06% (n=160) prescribed or offered this treatment to patients. According to the multivariate analysis, physicians aged 18-35 years (OR=1.97[1.00-3.91]; p=0.04), those who participated in a previous urogynecology fellowship (OR=2.34[1.34-4.09]; po0.01), those with relatively high volumes of POP cases (4 or +) (OR=2.23[1.21-4.47]; p=0.01) and those with PhD degrees (OR=2.75[1.01-7.54]; p=0.05) prescribed more pessaries. CONCLUSIONS: Most gynecologists did not prescribe VPs. Younger physician age, participation in a previous urogynecology fellowship, a PhD degree, and a relatively high volume of POP cases were associated with increased VP prescription rates
