A Ciranda Infantil e as crianças Sem Terrinha: educação e vida em movimento
Authors: Barcellos Luís Henrique Dos Santos , Torres Julio Cesar 
Published: June 2019

Este artigo tem como objetivo apresentar e discutir alguns aspectos da Educação Infantil do MST. O Movimento dos Trabalhadores Rurais Sem Terra é o principal movimento brasileiro de luta e resistência pela terra, e para defender suas bandeiras, elege como um dos fatores principais o desenvolvimento de uma educação emancipadora, que congregue trabalho e educação geridos por meio de relações e ações democráticas. Utilizando como metodologia a pesquisa de natureza bibliográfica e a análise documental, investigou-se a proposta educacional do MST para a infância no contexto das Cirandas Infantis, buscando a compreensão da concepção de criança e de infância Sem Terrinha. O MST busca evidenciar a desigualdade social e o descaso e negligência com as reais necessidades da população camponesa. A criança nesse processo é inserida como sujeito participativo, desde o seu nascimento, nas lutas travadas contra o capital. Para além de um sujeito de direitos, ela é um sujeito de luta.

Context.—Digital pathology (DP) implementations vary in scale, based on aims of intended operation. Few laboratories have completed a full-scale DP implementation, which may be due to high overhead costs that disrupt the traditional pathology workflow. Neither standardized criteria nor benchmark data have yet been published showing practical return on investment after implementing a DP platform.Objective.—To provide benchmark data and practical metrics to support operational efficiency and cost savings in a large academic center.Design.—Metrics reviewed include archived pathology asset retrieval; ancillary test request for recurrent/metastatic disease; cost analysis and turnaround time (TAT); and DP experience survey.Results.—Glass slide requests from the department slide archive and an off-site surgery center showed a 93% and 97% decrease, respectively. Ancillary immunohistochemical orders, compared in 2014 (52%)—before whole slide images (WSIs) were available in the laboratory information system—and 2017 (21%) showed $114 000/y in anticipated savings. Comprehensive comparative cost analysis showed a 5-year $1.3 million savings. Surgical resection cases with prior WSIs showed a 1-day decrease in TAT. A DP experience survey showed 80% of respondents agreed WSIs improved their clinical sign-out experience.Conclusions.—Implementing a DP operation showed a noteworthy increase in efficiency and operational utility. Digital pathology deployments and operations may be gauged by the following metrics: number of glass slide requests as WSIs become available, decrease in confirmatory testing for patients with metastatic/recurrent disease, long-term decrease in off-site pathology asset costs, and faster TAT. Other departments may use our benchmark data and metrics to enhance patient care and demonstrate return on investment to justify adoption of DP.
Sprint interval exercise versus continuous moderate intensity exercise: acute effects on tissue oxygenation, blood pressure and enjoyment in 18–30 year old inactive men
Authors: Kriel Yuri , Askew Christopher D. , Solomon Colin 
Published: June 2019

Background
Sprint interval training (SIT) can be as effective, or more effective, than continuous moderate intensity exercise (CMIE) for improving a primary risk factor for cardiometabolic disease, low cardiorespiratory fitness (CRF). However, there has been no direct comparison in inactive individuals, of the acute effects of a session of SIT with a work-matched session of CMIE on local oxygen utilisation, which is a primary stimulus for increasing CRF. Furthermore, post-exercise blood pressure (BP) and enjoyment, if symptomatic and low, respectively, have implications for safety and adherence to exercise and have not been compared between these specific conditions. It was hypothesised that in young inactive men, local oxygen utilisation would be higher, while post-exercise BP and enjoyment would be lower for SIT, when compared to CMIE.

Methods
A total of 11 inactive men (mean ± SD; age 23 ± 4 years) completed a maximal ramp-incremental exercise test followed by two experiment conditions: (1) SIT and (2) work-matched CMIE on a cycle ergometer on separate days. Deoxygenated haemoglobin (∆HHb) in the pre-frontal cortex (FH), gastrocnemius (GN), left vastus lateralis (LVL) and the right vastus lateralis (RVL) muscles, systemic oxygen utilisation (VO2), systolic (SBP) and diastolic (DBP) blood pressure and physical activity enjoyment scale (PACES) were measured during the experiment conditions.

Results
During SIT, compared to CMIE, ∆HHb in FH (p = 0.016) and GN (p = 0.001) was higher, while PACES (p = 0.032) and DBP (p = 0.043) were lower. No differences in SBP and ∆HHb in LVL and RVL were found between conditions.

Conclusions
In young inactive men, higher levels of physiological stress occurred during SIT, which potentially contributed to lower levels of post-exercise DBP and enjoyment, when compared to CMIE.

Authors: Li Wen , Zhou Zhicheng , Huang Jiaxiang , Zhang Guoyan , Awad Faisal N. , Chandankere Radhika , Guo Qi , Qi Xianghui 
Published: June 2019

Aims: D-tagatose is a natural ketohexose which can be used as a functional sweetener in foods, diary and beverages products. Isolation of new bacterial strains having the ability to produce D-tagatose is a continuously trending topic of research.
Study Design: Screening of strains with D-tagatose production by identification and determination of its ability to produce D-tagatose content.
Place and Duration of Study: School of Food and Biological Engineering, Jiangsu University between May 2018 and April 2019.
Methodology: We initially screened and identified the strains capable of producing D-tagatose through kimchi liquid, and determined the species and genetic characteristics of the strain by physiological, biochemical and molecular biological identification, and then determined the content of D-tagatose by high performance liquid chromatography. Finally calculate the ability of the strain to produce D-tagatose.
Results: In this study, 4 strains of lactic acid bacteria (LAB) were isolated from kimchi sample. The isolates were identified as Lactobacillus spp. (Lactobacillus plantarum, Lactobacillus fermentum and Lactobacillus salivarius) on the basis of morphological, physicochemical characteristics and analysis of 16S rDNA gene sequence. Because of the novelty, strain designated as L. salivarius UJS 003 was considered for D-tagatose yield. Fermentation of D-tagatose was carried out using galactose as substrate for 48 hr at 37 °C, and HPLC method was used to determine the yield. The experimental results exhibited a D-tagatose yield of 3.134 g/L by L. salivarius UJS 003.
Conclusion: The strain UJS 003 represented as a potent D-tagatose producer and could be useful in a variety of biotechnological and industrial processes, particularly food and beverage industries.

Published: June 2019

Thirty well-characterized pseudomonad isolates for plant growth-promoting traits were screened for their antagonistic activities against 20 isolates of Sclerotium rolfsii.
Out of the 30 pseudomonad isolates, PUR46 was found to be best against all 20 isolates of Sclerotium rolfsii, because of its unique ability to suppress the growth of mycelia as well as the sclerotia formation of most of the S. rolfsii isolates in vitro conditions. In our previous study, PUR46 was also found to be positive for growth promoting traits like phosphorus solubilization and ammonification. The results suggested that expression of one or more of the traits like antagonistic activity against S. rolfsii and solubilization of tri-calcium phosphate may help in controlling the pathogen besides enhancement of plant growth. In this study, our investigations clearly indicate that PGPR isolates PUR 46 may be exploited to be used as potential biocontrol agents against S. rolfsii in agriculture system.

Authors: Razzaque Md. Abdur , Alamgir Muhammed 
Published: June 2019

Aims: The aim of the study was to assess the indicator based climate change vulnerability of south west coastal Bangladesh and its future.
Place of Study: Four districts form south west coastal Bangladesh, having a total of 50 upazilas, have been selected as the study area. They are Satkhira, Khulna, Bagerhat, Pirojpur, Barguna and Patuakhali districts.
Methodology: This study has been conducted, using multivariate statistical techniques, to assess the vulnerabilities of the coastal region of Bangladesh by considering the IPCC framework of vulnerability studies. A total of 31 indicators have been selected of which 23 are socio-economic and 8 are biophysical which have been retrieved from the secondary sources. Principal Component Analysis (PCA) has been applied to derive unbiased weights of all indicators considering both present (2011) and the future (2050) climate change scenarios.
Results: This study has identiﬁed 7 principal components through PCA which has been grouped as PC1 (Demographic Vulnerability), PC2 (Economic Vulnerability), PC3 (Climatic Vulnerability), PC4 (Health Vulnerability), PC5 (Agricultural Vulnerability), PC6 (Infrastructural Vulnerability) and PC7 (Water Vulnerability). For all 7 PCA groups (termed as vulnerability proﬁle), the number of high and medium vulnerable coastal Upazilas will be significantly changed in the future. No of highly vulnerable Upazila will increase from 0 to 1 for PC1, unchanged for PC2, increase from 0 to 1 for PC3, from 32 to 33 for PC4, from 47 to 68 for PC5, decrease from 48 to 46 for PC6, and an increase from 14 to 21 for PC7, respectively.
Conclusion: Discrete spatial maps of each profile have been generated to assess the regional variation of all vulnerability proﬁles across the southwest coastal region of Bangladesh. The ﬁndings of this study might be useful for policy makers and planners.
Understanding the structural basis of species selective, stereospecific inhibition for Cryptosporidium and human thymidylate synthase
Authors: Czyzyk Daniel J. , Valhondo Margarita , Jorgensen William L. , Anderson Karen S. 
Published: June 2019

Thymidylate synthase (TS), found in all organisms, is an essential enzyme responsible for the de novo synthesis of deoxythymidine monophosphate. The TS active sites of the protozoal parasite Cryptosporidium hominis and human are relatively conserved. Evaluation of antifolate compound 1 and its R‐enantiomer 2 against both enzymes reveals divergent inhibitor selectivity and enzyme stereospecificity. To establish how C. hominis and human TS (ChTS and hTS) selectively discriminate 1 and 2, respectively, we determined crystal structures of ChTS complexed with 2 and hTS complexed with 1 or 2. Coupled with the previously determined structure of ChTS complexed with 1, we discuss a possible mechanism for enzyme stereospecificity and inhibitor selectivity.

Marmor Parium
Authors: Sickinger James P. 
Published: June 2019

Abstract

The Marmor Parium, or Parian Marble, is a fragmentary inscription that preserves a chronicle of events in Greek myth and history from the sixteenth to the third century
bce
. Its contents include items of a political, military, and cultural nature, each of which is dated by the name of an Athenian king or archon and by the number of years between those events and the year 264/3, the chronicle's endpoint. The author of the chronicle is unknown, and his dates for some events are inaccurate or different from those found in other sources. These and other features make the Parian Marble a valuable example of early Greek chronography.

Augusti liberti
Authors: Liu Jinyu 
Published: June 2019

AbstractTheAugusti liberti, or freedmen of the emperor(s), belonged to the imperial household and constituted an elite group among the population of servile origins in Roman society. The elite authors have left both scornful and positive depictions of a handful of imperial freedmen. Along with the literary evidence, thousands of inscriptions attest to the wide range of occupations and offices filled by theAugusti liberti, as well as their upward social mobility and influence both at Rome and in Italy and the provinces. The imperial freedmen were by no means a homogeneous group in terms of wealth, professional advancement, rank, and influence. A large number of theAugusti libertidealt with “domestic” matters of the palace. At least in the first two centuriesce, the functioning of the imperial government was also heavily dependent on the imperial freedmen serving as clerks as well as secretaries in charge of administrative matters.
Cleruchs, Egypt
Authors: Thompson Dorothy J. 
Published: June 2019

AbstractCleruchs were the army settlers in Ptolemaic Egypt, who were endowed by the king with a plot of land to provide a livelihood and a home base when they were not employed on active service. They thus became tied to the new regime, which was important in the competitive world of the early Hellenistic period following Alexander's conquest of the east. Over time the status of both cleruchs and cleruchic land developed and changed, until under the Romans the status of each was absorbed in other categories.
Patron, patronage, Roman
Authors: Liu Jinyu 
Published: June 2019

AbstractThe Latin wordpatronusmay denote a legal advocate, a former master of a freedman, or a protector or defender of individuals or collectivities. The term patronage is closely connected with the last of these meanings. Although scholars have used patronage to convey a wide range of unequal social relationships in the Roman world, they have also cautioned against seeingamicitia(friendship), among others, simply as a euphemism for patron–dependent protégé relations. Scholarly opinions differ as to whether patronage undermined the institutional workings of the Roman state, or if it maintained and reproduced the state's power relations.

Improvement of BiVO4 Photoanode Performance During Water Photo‐Oxidation Using Rh‐Doped SrTiO3 Perovskite as a Co‐Catalyst
Authors: Zhang Yaping , Li Yang , Ni Diqing , Chen Zhiwei , Wang Xiao , Bu Yuyu , Ao Jin‐Ping 
Published: June 2019

AbstractIn this work, a water splitting photoanode composed of a BiVO4 thin film surface modified by the deposition of a rhodium (Rh)‐doped SrTiO3 perovskite is fabricated, and the Rh‐doped SrTiO3 outer layer exhibits special photoelectrochemical (PEC) oxygen evolution co‐catalytic activity. Controlled intensity modulated photo‐current spectroscopy, electrochemical impedance spectroscopy, and other electrochemical results indicate that the Rh on the perovskite provide an oxidation active site during the PEC water oxidation process by reducing the reaction energy barrier for water oxidation. Theoretical calculations indicate that the water oxidation reaction is more likely to occur on the (110) crystal plane of Rh‐SrTiO3 because the oxygen evolution reaction overpotential on the (110) crystal plane is reduced significantly. Therefore, the obtained BiVO4/Rh5%‐SrTiO3 photoanode exhibits an optimized PEC performance. In particular, it facilitates the saturation of the photocurrent density. Thus, the presence of doped Rh in SrTiO3 can reduce the amount of noble metals required while achieving excellent and stable oxygen evolution properties.
CsPbBr3 Quantum Dots 2.0: Benzenesulfonic Acid Equivalent Ligand Awakens Complete Purification

Published: June 2019

AbstractThe stability and optoelectronic device performance of perovskite quantum dots (Pe‐QDs) are severely limited by present ligand strategies since these ligands exhibit a highly dynamic binding state, resulting in serious complications in QD purification and storage. Here, a “Br‐equivalent” ligand strategy is developed in which the proposed strong ionic sulfonate heads, for example, benzenesulfonic acid, can firmly bind to the exposed Pb ions to form a steady binding state, and can also effectively eliminate the exciton trapping probability due to bromide vacancies. From these two aspects, the sulfonate heads play a similar role as natural Br ions in a perfect perovskite lattice. Using this approach, high photoluminescence quantum yield (PL QY) > 90% is facilely achieved without the need for amine‐related ligands. Furthermore, the prepared PL QYs are well maintained after eight purification cycles, more than five months of storage, and high‐flux photo‐irradiation. This is the first report of high and versatile stabilities of Pe‐QD, which should enable their improved application in lighting, displays, and biologic imaging.
Spontaneous Formation of Nanogap Electrodes by Self‐Peeling Adhesion Lithography
Authors: Luo Sihai , Hoff Bård H. , deMello John C. 
Published: June 2019

AbstractAdhesion lithography (“a‐lith”) is a simple method for forming nanoscale gaps between dissimilar metals. In its usual form, a metal is patterned on a substrate, and conformally coated with an alkyl‐functionalized self‐assembled monolayer, rendering it nonadhesive to other metals; a second metal is then deposited uniformly over the full area of the substrate; finally, the parts of the second metal that are in contact with the self‐assembled monolayer are stripped away using an adhesive tape or film, leaving the first and second metals side‐by‐side on the substrate, with a nanoscale spacing between them. It is shown here that, by depositing onto the second metal an adhesive film with high internal strain, it is possible to induce spontaneous delamination of the peeling layer without the need for any applied force. The modified procedure simplifies implementation and eliminates external stresses that can cause unwanted widening of the gap. The resultant electrode separations of ≈10 nm are amongst the smallest values achieved to date using adhesion lithography.

Published: June 2019

AbstractBackgroundWe estimated the proportion and number of female breast cancer cases in Canada attributable to night shift work, a probable cause of breast cancer.MethodsLevin's equation was used to calculate population attributable fractions (PAFs) among Canadian women who ever worked night/rotating shifts from 1961 to 2000, accounting for labor turnover and survival to the year 2011. The calculated PAFs were applied to 2011 Canadian breast cancer incidence statistics to obtain the number of attributable cases.ResultsApproximately 1.5 million women ever worked night/rotating shifts during 1961‐2000 and survived to 2011. The PAFs ranged from 2.0% (95% confidence interval [CI]: 1.4‐6.2) to 5.2% (95% CI: 3.7‐13.6), and 470 to 1200 incident breast cancer cases in 2011 were likely due to shift work, of which 38% would have been diagnosed among women in health‐related occupations.ConclusionsMore research is needed to increase the certainty of this association, but current evidence supports workplace‐based prevention.
Dynamical Measurement's Uncertainty in the Curved Space‐Time
Authors: Ming Fei , Wang Dong , Ye Liu 
Published: June 2019

AbstractThe dynamical characteristics of measurement's uncertainty are investigated under two modes of Dirac field in the Garfinkle–Horowitz–Strominger dilation space‐time. It shows that the Hawking effect induced by the thermal field would result in an expansion of the entropic uncertainty with increasing dilation‐parameter value, as the systemic quantum coherence reduces, reflecting that the Hawking effect could undermine the systemic coherence. Meanwhile, the intrinsic relationship between the uncertainty and quantum coherence is obtained, and it is revealed that the uncertainty's bound is anti‐correlated with the system's quantum coherence. Furthermore, it is illustrated that the systemic mixedness is correlated with the uncertainty to a large extent. Via the information flow theory, various correlations including quantum and classical aspects, which can be used to form a physical explanation on the relationship between the uncertainty and quantum coherence, are also analyzed. Additionally, this investigation is extended to the case of multi‐component measurement, and the applications of the entropic uncertainty relation are illustrated on entanglement criterion and quantum channel capacity. Lastly, it is declared that the measurement uncertainty can be quantitatively suppressed through optimal quantum weak measurement. These investigations might pave an avenue to understand the measurement's uncertainty in the curved space‐time.
