Published: June 2020

RESUMO: Avaliou-se a substituição da brita basáltica existente no concreto por material alternativo em abundância no município de Santarém-PA: a laterita. Foi avaliado o desempenho do concreto incorporado com agregado laterítico in natura em substituição parcial ao agregado graúdo de brita basáltica nos teores de 20% e 50%. Realizou-se a caracterização dos agregados graúdo e miúdo. De acordo com o método da ABCP, determinou-se o traço de referência em massa 1:1,71:3,03:0,53; confeccionou-se corpos-de-prova cilíndricos 10x20 cm utilizando 3 traços diferentes, de modo a substituir a brita basáltica pelo agregado laterítico, em 20% e 50%. Para cada traço foram quantificados a sua consistência, por meio do ensaio de abatimento do tronco de cone, resistência à compressão axial, resistência à tração por compressão diametral e módulo de elasticidade aos 28 dias. A substituição do agregado convencional de brita basáltica por agregado laterítico em seu estado natural promoveu diminuição da resistência a compressão simples, da resistência à tração por compressão diametral e do módulo de elasticidade com a inclusão do agregado laterítico na mistura. Destaca-se que acima de determinado teor de substituição o concreto torna-se inviável devido a necessidade de adicionar aditivo plastificante para manter a consistência desejada e que as duas misturas incorporadas com agregado laterítico se mostraram muito semelhantes após os 28 dias, no que tange a ganhos de resistência a compressão.
ABSTRACT: This study is about the replacement of basaltic origin crushed stone by alternative material present in the municipality of Santarém, Pará State: the laterite. The aim were to evaluate the performance of concrete incorporated with natural lateritic aggregate, replacing the of crushed stone in 20% and 50%. The first stage was characterizing the coarse and fine aggregates that made up the studied concrete. According to ABCP dosing method it was determined the mass reference trait 1: 1.71: 3.03: 0.53; bodies of 10x20 cm were made for cylindrical test, using three different strokes so that the basaltic crushed stone gradually replaced by the lateritic aggregate in proportions of 20% and 50%. For each trait its consistency was quantified by means of the tapering test, axial compression strength, diametric compression tensile strength and the modulus of elasticity at 28 days. Was observed that the replacement of the conventional aggregate basalt crushed stone for aggregate of laterite in natural state promoted a decrease in the value of simple compressive strength, diametric tensile strength and modulus of elasticity with inclusion of a larger amount of lateritic aggregate in the mixture. It is noteworthy that above a certain substitution content, the concrete becomes not feasible due to the need for a large increase in the amount of plasticizer additive to the desired consistency is maintained and the two blends incorporated with lateritic showed very similar after 28 days in terms of gains in compressive strength.
Lo Duca and Dreyer: Baroque Music, Extant Recordings, and Aleatoric Synchrony
Authors: Greig Donald 
Published: June 2020

AbstractIn 1952, the Italian film historian Lo Duca, having discovered a lost print of Carl Theodor Dreyer’s La Passion de Jeanne d’Arc (1928), created a sonorized version of the film. This article details the history of the project and examines the use of baroque music with the moving image more generally. It also considers the vicissitudes of using pre-existent recordings and proposes a notion of aleatoric synchronization.
Poster Queers: A Visual Analysis of an LGBTQ+ Film Festival
Authors: Huth Jessica L. 
Published: June 2020

Abstract
This study concerns itself with the visual representations of The Chicago LGBTQ+ International Film Festival (a.k.a. Reeling) with specific attention paid to their marketing campaign materials, as exemplified by the annually created festival poster. It is my aim to situate these posters alongside the historical contexts of queer identity, sociopolitical advocacy, and LGBTQ+ cinema. This analysis will navigate the 36-year period of the festival organization’s existence, providing key in-depth interrogations into the decades, images, and trends both visual and narrative. My unpacking and theoretical discussions of the festival’s visual culture has been informed by the practices of semiotics and film genre theory. These methods were employed to answer the primary research question: How have the poster advertisements, as visual signifiers for The Chicago LGBTQ+ International Film Festival, symbolized their organization’s mission, represented queer identities, and engaged with the politically contested history of queer cinematic representation?

Published: June 2020

Insufficient light intensity inhibits the growth of cultivated herbaceous peony and decreases its economic value. Owing to the increased demand for shade-tolerant herbaceous peony, the selection of appropriate parents for hybridization is essential. Paeonia anomala, Paeonia intermedia and Paeonia veitchii can grow under shade conditions in their natural habitats; however, their photosynthetic capacities under shade have not been studied. In this study, we simulated low light intensity (30% sunlight) and evaluated the morphological, photosynthetic and chlorophyll fluorescence parameters of these three species. Moreover, the shade tolerance of these species as well as two common cultivars (Paeonia lactiflora ‘Da Fugui’, which is suitable for solar greenhouse cultivation, and P. lactiflora ‘Qiao Ling’, which is not suitable for solar greenhouse cultivation) was evaluated. The results showed that under shade, the leaf area of P. anomala and P. intermedia increased, the single flowering period of P. intermedia and P. veitchii was prolonged, and the flower color of P. veitchii faded. With respect to P. anomala, P. intermedia and P. veitchii, shade eliminated the photosynthetic ‘lunch break’ phenomenon and decreased photoinhibition at midday. Furthermore, the maximum photochemical efficiency (Fv/Fm) and maximum primary photochemical yield (Fv/Fo) of photosystem II (PSII) in the three species improved significantly, and their changes in light dissipation were different. The shade tolerance of the tested accessions was in the order P. veitchii > P. intermedia > P. anomala > ‘Da Fugui’ > ‘Qiao Ling’, showing that the three wild species were better adapted to low light intensity than the cultivars. Thus, P. anomala, P. intermedia and P. veitchii could potentially be used in the development of shade-tolerant herbaceous peony cultivars.

Published: June 2020

This paper examined the demographic, temporal and spatial distribution of the coronavirus (COVID-19) epidemic in Vietnam. COVID-19 data abstracted from the official website of Vietnam Ministry of Health, which provides details of each new, infected case, including age, sex, place of residence, and travel history. Vietnam has only had 268 confirmed cases of COVID-19 and no reported fatality as of April 19, 2020. Of those who tested positive, 223 (83.2%) have recovered and discharged from hospitals. Younger age and men were significantly associated with a history of international travel. Women were more likely to get infection inside the country. Vietnam’s early and aggressive responses including a locally developed diagnostic test, a rapid rollout of suspected cases, tracing of contacts and self-isolation of contacts and communities in which there had been a positive case was effective in limiting spread and keeping the incidence of Covid-19 low. The Vietnamese response could serve as a model for other countries.

Aims: Information on ichthyoplankton is an important tool in determining reproduction periods that if associated to environmental variables. The abundance and distribution of ichthyoplankton and their relationships to some environmental variables of the water in Lake Buyo were analyzed. Preferred microhabitats for spawning, dispersion and nursery were also verified.
Place and Duration of Study: The study was conducted monthly from April 2019 through September 2019 in lake Buyo.
Methodology: Acylindro-conical net (500 µm in mesh opening size, 50 cm in mouth diameter) and stream net (7 mm in mesh opening size) were used.
Results: During the study period, the very lowest densities of eggs (1-2 ind/10 m3) and larvae were recorded in sites (S3 and S8) located relatively far from shoreline and the highest (186-724 ind/10 m3) in sites located near shoreline. The sites closed to littoral were identified as spawning areas by fish species during study period and sites located in deep water are not spawning sites. No significant difference between seasons was observed for each sampling site.
Conclusion: Eggs and larvae distribution in Lake Buyo was strongly influenced by water depth, water temperature, dissolved oxygen, percentage of gravel, percentage of coarse sand and proportion of very fine sand.

Aims: To study the importance of differential diagnosis of breast cancer using Magnetic resonance mammography.
Study Design: Cohort Study.
Place and Duration of Study: The study was conducted Republican Specialized Scientific-Practical Medical Center of Oncology and Radiology between 2017 and 2019.
Methodology: The study included a clinical and instrumental examination of 70 women with suspected breast cancer. The age of the patients was 26-75 years (average age - 49.0 ± 2 years). All patients underwent core biopsy. The procedure was performed in a horizontal position of the patient, a needle was brought in and a “shot” was performed, during which a tissue sample was taken from the focus of interest. In 5 (7.1%) cases, the second stage of verification of the diagnosis was carried out through sectoral resection with an urgent histological examination. The resulting material is sent for cytological and histological studies.
Results: The sensitivity of x-ray mammography in detecting breast tumors was 83.4%, specificity 60.0%. The sensitivity of ultrasound in the diagnosis of breast cancer was 86.4%, specificity - 44.8%. In our observations of breast MRI, the sensitivity was 97.5%, specificity 87.2%. Magnetic resonance mammography is considered a more effective method in the early diagnosis of breast cancer.
Conclusion: Breast MRI is highly sensitive, specific and accurate in assessing the prevalence and differential diagnosis between a benign and malignant process.

This experiment was conducted at the Bioenergy laboratory of Groupe de Génies Congolais (GGC) at the Université Loyola du Congo in Kinshasa, D.R.Congo. The experiment started on May 23, 2019 and ended on July 17, 2019. The study focused on the relationship between solids concentration and the kinetic of anaerobic digestion of goat droppings in the methanation process. The feedstock consisted of goat droppings waste made into slurry of four solids concentration (SC); A=50%, B=38%, C=30% and D=25%. Each SC was repeated three times. Feedstocks were inserted in laboratory scale anaerobic digesters constructed from 5L plastic containers. The results revealed clearly that the time required for the production of biogas depends on SCs. The ratio D (1/3), i.g. 75% of water and 25% of biomass produced the biogas in 3 weeks (±22 days) and the ratio A (1/1), 50% of water and 50% of biomass, in 7 weeks and a few days (±53 days). The ratio C (1/2), 66.6% of water in the mixture, provided the biogas in ± 26 days (approximately 4 weeks) and finally, it took ±30 days (4 weeks and a few days) for ratio B to produce biogas rich in CH4 (<50%). The equation f(x)= 1.1x + 1 can be used to predict the approximative number of days to produce a biogas containing more than 50% of CH4.
The average temperature inside the reactors was found to be 28.5 ± 0.8°C during the combustion testing process implying that the reactors designed at the GGC were operating in a mesophilic regime. Finally, the pH of the digestates obtained from reactors had an average of 9.0 ± 0.2.

Escherichia coli was isolated in all eggs collected from the rearing systems and collection periods except battery cage system in the morning and outdoor system in the morning. Staphilococcus aureus was isolated in eggs collected from all the housing systems and collection periods except in outdoor system in the afternoon. Aspergillus niger was isolated across all the housing systems and collection periods.
Conclusion: From the results, it shows that the different eggshells from the three rearing systems were contaminated with bacteria and fungi loads at varying levels.
Does exposure to facial composites damage eyewitness memory? A comprehensive review

Published: June 2020

SummaryEyewitnesses often create face likenesses, which are published in the hope that potential suspects will be reported to the police. Witnesses exposed to another witness's composite, however, may be positively or negatively influenced by such composites. A good likeness may facilitate identification, but a bad likeness that resembles an innocent suspect may lead to a misidentification (“mix‐up”). We offer a theoretical review, and comprehensively summarize extant studies descriptively because most studies did not report enough statistical details to warrant a formal meta‐analysis. Some studies showed negative exposure effects, particularly when the innocent suspect and composite shared misleading features. Studies that exposed witnesses to “good” composites reported positive or no effects on lineup performance, and some highly powered studies also showed no effect. We outline suggestions for further investigations under ecologically valid conditions. We also make recommendations for investigative practice, and the evaluation of identification evidence by fact finders or courts.
Spider‐Web‐Inspired PM0.3 Filters Based on Self‐Sustained Electrostatic Nanostructured Networks

Published: June 2020

AbstractParticulate matter (PM) pollution has become a serious public health issue, especially with outbreaks of emerging infectious diseases. However, most present filters are bulky, opaque, and show low‐efficiency PM0.3/pathogen interception and inevitable trade‐off between PM removal and air permeability. Here, a unique electrospraying–netting technique is used to create spider‐web‐inspired network generator (SWING) air filters. Manipulation of the dynamic of the Taylor cone and phase separation of its ejected droplets enable the generation of 2D self‐charging nanostructured networks on a large scale. The resultant SWING filters show exceptional long‐range electrostatic property driven by aeolian vibration, enabling self‐sustained PM adhesion. Combined with their Steiner‐tree‐structured pores (size 200–300 nm) consisting of nanowires (diameter 12 nm), the SWING filters exhibit high efficiency (>99.995% PM0.3 removal), low air resistance (<0.09% atmosphere pressure), high transparency (>82%), and remarkable bioprotective activity for biohazard pathogens. This work may shed light on designing new fibrous materials for environmental and energy applications.

Published: June 2020

AbstractA radiative cooling garment is proposed as a promising strategy for ordinary people to attain high thermal comfort indoors and outdoors. However, low production and poor cooling capability restrict its wide applications. Herein, a high‐performance fiber and its textile with pore and wrinkle structures are fabricated that consist of polyethylene (PE) and polyethylene oxide. This specific structure endows the fiber and textile with high IR absorbance/emissivity (90.97%) and sunlight reflectance (93.77%). Therefore, the hybrid porous PE fiber and textile show good cooling capabilities and avoid the human body overheating by 6.8 °C under direct solar irradiation. The inner temperature of the transparent house with a roof covered by the textile decreases by 20.3 and 12.5 °C compared to the states of no extra cover and cotton cover, respectively. Apart from that, the results of the simulating and real human body measurements demonstrate that the porous PE textile enables the human body to acquire the same thermal comfort as the bare state. More importantly, the porous PE fiber and textile are superlight, flexible, moisture‐permeable, and waterproof, and meanwhile, have excellent tensile strength and UV protection properties. The good comprehensive performance indicates that the textile is appealing for fabricating summer clothes.

Published: June 2020

AbstractControlled doping of transition‐metal dichalcogenide (TMDC)‐layered materials is of great importance for practical device application. Doping of TMDCs and tuning of the bandgap properties remain challenging owing to the difficulty of breaking covalent bonds. In this work, the doping of V, Fe, and Nb atoms into MoSe2 is successfully synthesized using the chemical vapor transport method. By the absorption of V or Nb dopants, the intrinsic n‐type MoSe2 is tuned to be of p type. A p‐n diode based on a homojunction is fabricated by stacking the n‐ and p‐type MoSe2 vertically. The photoresponse range of intrinsic MoSe2 is only up to 785 nm. However, the photodetector based on the doped MoSe2 flake with V, Fe, and Nb can be used up to the near‐infrared (1550 nm) region at room temperature. Furthermore, the photoresponse wavelength of a V‐doped MoSe2 could reach up to 10 µm. The results indicate that the elemental doping methods could enrich the electrical and optical application prospects of MoSe2.

Published: June 2020

AbstractTargeted cancer therapies have been extensively tested with the purpose to selectively suppress tumor growth and to avoid harming healthy tissue. However, failure to escape endosomes upon receptor‐mediated endocytosis is a major obstacle limiting the efficacy of targeted cancer therapeutics. Here, novel target‐switchable intracellular toxin delivery systems (TiTDS) are presented which use the catalytic and translocation domain of diphtheria toxin (dtA‐T) as an intracellular toxin delivery platform and affibody molecules targeting human epidermal growth factor receptor 2 or epidermal growth factor receptor (HER2Afb or EGFRAfb) as target‐specific ligands. The intracellular toxin delivery platform and the affibody molecules are genetically fused with SpyCatcher (SC) protein and SpyTag (ST) peptide, respectively, to generate dtA‐T‐SC and ST‐HER2Afb or ST‐EGFRAfb modules. These modules can be individually purified and post‐translationally ligated to produce dtA‐T/HER2Afb or dtA‐T/EGFRAf. dtA‐T/HER2Afb and dtA‐T/EGFRAfb can selectively bind to their corresponding target cancer cells, efficiently enter the cells through receptor‐mediated endocytosis, successfully escape endosomes, and release toxins into the cytosol. They exhibit high target‐specific cytotoxicity in vitro and can significantly reduce tumor masses in vivo. TiTDS is a promising targeted cancer therapy platform because of its high target specificity, effective intracellular delivery of active toxins with improved therapeutic efficacy, and target switchability.

Published: June 2020

AbstractControl of blood microflow is crucial for the prevention and therapy of blood disorders, such as cardiovascular diseases and their complications. Conventional control strategies generally implant exogenous synthetic materials into blood vessels as labeling markers or actuating sources, which are invasive and incompatible with biological systems. Here, a label‐free, noninvasive, and biocompatible device constructed from natural red blood cells (RBCs) for controlling blood microflow in vivo is reported. The RBCs, optically manipulated, arranged, and rotated using scanning optical tweezers, can function as an optofluidic switch for targeted switching, directional enrichment, dynamic redirecting, and rotary actuation of blood microflow inside zebrafish. The regulation precision of the switch is determined to be at the single‐cell level, and the response time is measured as ≈200 ms using a streamline tracking method. This in vivo optofluidic switch may provide a biofriendly device for exploring blood microenvironments in a noncontact and noninvasive manner.
