RESUMO: O presente trabalho teve como objetivo estimar o conteúdo volumétrico de água retida no solo utilizando funções de pedotransferência desenvolvidas a partir de um banco de dados específico criado para as condições edafoclimáticas da região do Agreste Paraibano. Foram utilizados dados de atributos físicos e químicos de solos de 240 amostras de solo deformadas e indeformadas. As variáveis de cada função de pedotransferência foram obtidas através de regressão múltipla utilizando a opção stepwise e a eficiência das funções analisadas através dos indicadores estatísticos R², ME e RMSE. As quantidades de água retidas foram determinadas nas tensões -0,006, -0,01, -0,033, -0,1, -0,3, -0,5, -1,0 e -1,5 Mpa. A correlação entre variáveis estruturais e retenção de água no solo refletiu na precisão das PTFs; As PTFs gerados apresentaram baixa variação em torno da linha 1:1 e boa precisão e podem ser utilizados para estimar o teor de água retido nas classes de solos avaliadas.
ABSTRACT: The present research aimed to estimate the volumetric content of water retained in the soil using pedotransfer functions developed from a specific database created for the edaphoclimatic conditions of Agreste Paraibano region.

Selenium is an essential trace element which, at adequate levels, presents different beneficial biological effects, such as cancer regression, tissue development and protection against oxidative damage. The positive effects of this element are related to the expression of selenoproteins and their ability to modulate the immune system and the oxidative stress response. In Chagas disease and sleeping sickness, selenium supplementation has shown blood parasitism reduction and the alleviation of specific aspects of the diseases, such as diminishing anemia in sleeping sickness or minimization of myocardial and right ventricular chamber damage in Chagasdisease. Although the influence of selenium in trypanosomiasis has been investigated, the direct effects of sodium selenite supplementation on trypanosome cells are poorly understood. Treatment of Trypanosoma cruzi cultures with low selenium doses demonstrated different results, according to the parasite evolutive form analyzed. Epimastigote cultures supplemented with 100 nM of sodium selenite presented cell growth increment, which varies from 10 to 40% according to the parasite strain assayed. Selenium concentration around 600nM leads to a 30% increase in the amastigote form number, whereas, at the same dose, the mammal host cell presented no cellular growth alteration. For the bloodstream form, the results agree with theliterature, and all sodium selenite concentrations tested, demonstrated a reduction in parasite viability. The data suggest that selenium supplementation, under specific conditions, could increase T. cruzi viability, demonstrating that a strategy for using selenium as an adjuvant in Chagas disease treatment requires additional experimentation. KEY WORDS: Selenium; trypanosomiasis; Chagas disease; Trypanosoma cruzi.

Diversity and Inclusion in different types of childcare organizations as experienced by managers and their employees
Childcare centers are organizations that differ in structural and cultural characteristics. The present comparative case study examined how Dutch childcare centers match different organization types and related the identified organization types to the implementation of diversity and inclusion policy. Diversity and inclusion in organizations concerns climate-dimensions, such as providing equal opportunities, allowing influence on decision-making and stimulating professional development for all staff. Semi-structured interviews were conducted with 13 managers and 24 pedagogical practitioners in 13 childcare centers. Content-analysis of the interviews showed that employees in all centers experience equal opportunities, however the content and form of these opportunities differed according to the type of organization. Employees in childcare centers with a comparatively strong orientation on professional performance reported positive experiences with group-collaboration, team-professionalization and collective decision-making. Employees in childcare centers with a comparatively strong market orientation reported positive experiences with possibilities for individual development and autonomy in their daily work. The experiences of the employees match the differences in organizational climate as reported by the location managers, emphasizing either collaboration in teams or employees’ individual responsibility, depending on the type of organization.

Published: June 2020

Background
Differences in the muscular activity between the high-bar back squat (HBBS) and the low-bar back squat (LBBS) on the same representative group of experienced powerlifters are still scarcely investigated. The main purpose of the study was to compare the normalized bioelectrical activity and maximal angles within single homogeneous group between the HBBS and LBBS for 60% one repetition maximum (1RM), 65% 1RM and 70% 1RM.

Methods
Twelve healthy men (age 24.3 ± 2.8 years, height 178.8 ± 5.6 cm, body mass 88.3 ± 11.5 kg), experienced in powerlifting performed HBBS and LBBS with comparable external loads equal 60% 1RM, 65% 1RM, and 70% 1RM. Electromyography (EMG) signals of muscle groups were synchronously recorded alongside kinematic data (joints angle) by means of a motion capture system.

Results
EMG activity during eccentric phase of squat motion were significantly higher during LBBS than in HBBS for all selected muscles (60% 1RM and 65% 1RM) (p < 0.05). All examined muscles were more activated during concentric phase of the squat cycle (p < 0.05). In the concentric phase, significant differences between the loads were generally not observed between just 5% 1RM change in load level for LBBS.

Conclusions
Our results confirmed significant differences in muscles activation between both squat techniques. Muscle activity during eccentric phase of squat motion were significantly higher during LBBS than HBBS. The differences are crucial for posterior muscle chain during eccentric phase of squat cycle.

Tick‐borne encephalitis virus (TBEV), a member of flaviviruses, represents a serious health threat by causing human encephalitis mainly in central and eastern Europe, Russia, and northeastern Asia. As no specific therapy is available, there is an urgent need to understand all steps of the TBEV replication cycle at the molecular level. One of the critical events is the packaging of flaviviral genomic RNA by TBEV C protein to form a nucleocapsid. We purified recombinant TBEV C protein and used a combination of physical–chemical approaches, such as size‐exclusion chromatography, circular dichroism, NMR spectroscopies, and transmission electron microscopy, to analyze its structural stability and its ability to dimerize/oligomerize. We compared the ability of TBEV C protein to assemble in vitro into a nucleocapsid‐like structure with that of dengue C protein.
Promotion of Proangiogenic Secretome from Mesenchymal Stromal Cells via Hierarchically Structured Biodegradable Microcarriers

Published: June 2020

AbstractAdipose‐derived mesenchymal stromal cells (AdMSC) release numerous soluble factors capable of stimulating angiogenesis. Improved methods for delivering these cells to maximize their potency are now sought that ideally they retain viable cells in the target tissue while promoting the secretion of angiogenic factors. Substrate surface topography is a parameter that can be used to manipulate the behavior of AdMSC but challenges exist with translating this parameter into materials compatible with minimally invasive delivery into tissues for in situ delivery of the angiogenic secretome. The current study investigates three compositions of hierarchically structured, porous biodegradable microcarriers for the culture of AdMSC and the influence of their surface topographies on the angiogenic secretome. All three compositions perform well as cell microcarriers in xeno‐free conditions. The attached AdMSC retain their capacity for subsequent trilineage differentiation. The secretome of AdMSC attached to the microcarriers consists of multiple proangiogenic factors, including significantly elevated levels of vascular endothelial growth factor, which stimulates angiogenesis in vitro. The unique properties of hierarchically structured, porous biodegradable microcarriers investigated in this study offer a radically transformative approach for achieving targeted in vivo delivery of AdMSC and enhancing the potency of their proangiogenic activity to induce neovascularization in ischemic tissue.

AbstractHalide perovskites have shown tremendous potential for next‐generation flat‐panel laser displays due to their remarkable optoelectronic properties and outstanding material processability; however, the lack of a general approach for the fast growth of perovskite laser arrays capable of electrical operations impedes actualization of their display applications. Herein, a universal and robust wettability‐guided screen‐printing technique is reported for the rapid growth of large‐scale multicolor perovskite microdisk laser arrays, which can serve as laser display panels and further be used to realize current‐driven displays. The perovskite microlasers are precisely defined with controlled physical dimensions and spatial locations by such a printing strategy, and each perovskite microlaser serves as a pixel of a display panel. Moreover, the screen‐printing procedure is highly compatible with light‐emitting diode (LED) device architectures, which is favorable for the mass production of micro‐LED arrays. On this basis, a prototype of a current‐driven display is demonstrated with desired functionalities. The outstanding performance and feasible fabrication of screen‐printed perovskite microlaser arrays embedded in LEDs provide deep insights into the concepts and device architectures of electrically driven laser display technology.

Published: June 2020

AbstractDielectric composites based on polybasic components with hierarchical structures have promising potentials for electromagnetic absorber. However, strategy to strengthen coupling of transition metal oxides still demands to be optimized to enhance electromagnetic loss. Herein, inspired by the hierarchical structure of balsam pear, ultrafine ZnO is uniformly distributed and tightly capped in MnO2 by self‐assembly hydrothermal method. The unique hierarchical structure provides abundant polarization centers with large specific surface area. The compositions promote attenuation performance of electromagnetic waves, enhance relative permittivity and satisfy impedance matching as compared with that of pure ZnO or MnO2. The effective bandwidth (RL< −10 dB) reaches 5.93 GHz obtained with thin thickness of 1.8 mm. The effective bandwidth reaches 15 GHz via regulating their thickness. The fabricated MnO2/ZnO composites can achieve great adaptability in microwave. MnO2/ZnO composites keep stability even heated 700 °C in air. The phase and weight remain unchanged. The proposed interfacial modulation strategy can provide new opportunities for the design of efficient electromagnetic absorber with thermal stability.
Reducing Friction by Control of Isoelectric Point: A Potential Method to Design Artificial Cartilage
Authors: Yuan Shihua , Chen Xinchun , Zhang Chenhui 
Published: June 2020

AbstractRelative motion between artificial cartilages is too slow to form a sufficient lubricating film for hydrodynamic lubrication, and this can result in large friction and wear. Hydration lubrication is effective in reducing friction at low speeds, and the lubricity is mostly determined by surface charges, which can be assessed by isoelectric point (IEP). Therefore, by controlling the IEP of friction pairs, ultralow friction can be achieved even with weak hydrodynamic lubrication. Here, a negatively charged material is synthesized by grafting carboxylate anions into an epoxy resin matrix. Compared with pristine epoxy resin (IEP = 6.0), the modified epoxy resins (IEP = 3.8, IEP = 3.0) show better tribological properties. In particular, at low speeds (4.7 and 1.2 mm s−1), the friction coefficients are as low as 0.02–0.04, and the average contact pressures are ≈10 MPa, when a NaCl solutions are used as the lubricants. Furthermore, the addition of hydroxyapatite to the modified epoxy resin not only increases its bioactivity, but also reduces friction. Superlubricity can be achieved for the speeds higher than 23.5 mm s−1. These results provide a method to design artificial cartilage with good tribological and bearing capacity.

AbstractThe transition metal selenides M1+ySe2 (M = V, Ti) have intriguing quantum properties, which make them target materials for controlling properties by thinning them to the ultrathin limit. An appropriate approach for the synthesis of such ultrathin films is by molecular beam epitaxy. Here, it is shown that such synthesized V‐ and Ti‐Se2 films can undergo a compositional change by vacuum annealing. Combined scanning tunneling and photoemission spectroscopy is used to determine compositional and structural changes of ultrathin films as a function of annealing temperature. Loss of selenium from the film is accompanied by a morphology change of monolayer height islands to predominantly bilayer height. In addition, crystal periodicity and atomic structure changes are observed. These changes are consistent with a transition from a layered transition metal dichalcogenide (TMDC) to ordered intercalation compounds with V or Ti intercalated in between two layers of their respective TMDCs. These observations may clear up misconception of the nature of previously reported high‐temperature grown transition metal selenides. More significantly, the demonstrated control of the formation of intercalation compounds is a key step toward modifying properties in van der Waals systems and toward expanding material systems for van der Waals heterostructures.

AbstractThe elucidation of the 3D structure of DNA revolutionized modern science and created the basis for the field of molecular biology. The advent of DNA sequencing, and further refinement with Next‐Generation Sequencing (NGS) techniques, has made possible the enormous accumulation of data, which are useful for understanding the molecular mechanisms associated to various complex and rare diseases. Thanks to these advances, today it is known that several mechanisms regulate gene expression without the occurrence of mutations in the genome, a phenomenom known as Epigenetics and Epigenomics. The main mechanisms involved are DNA methylation, histone modifications, and non‐coding RNA transcription. The knowledge of these mechanisms applied to biomedicine has enabled the emergence of several fields, especially precision medicine, which is based on the genetic and epigenetic profiles of patients applied to personalized diagnostics and treatments. In this review, the history of the scientific advances that have enabled the development of precision medicine will be discussed, with a focus in epigenetics. Moreover, several molecules that have been approved for use or have the potential in epigenetic therapies (epidrugs) will also be discussed here, those of which act on targets responsible for maintaining the correct epigenetic pattern or correcting wrong patterns in diseases.

AbstractWhile adding a third component to a binary blend in the active layer of an organic solar cell is a promising approach to improve device performance, the control of active‐layer morphology also becomes more complex. Here, a combination of molecular dynamics simulations and long‐range corrected density functional theory calculations is used to examine the intermolecular packing and electronic properties in two polymer donor/small‐molecule acceptor binary blends, D/A1 (donor/acceptor1) and D/A2 (donor/acceptor2), in order to gain insight into the D/A1/A2 ternary blend. The focus is on the blends of the 4‐(3‐(2‐decyltetradecyl)‐5′‐(2,3‐difluoro‐4‐(5‐methylthiophen‐2‐yl)phenyl)‐[2,2′‐bithiophen]‐5‐yl)‐7‐(4‐(2‐decyltetradecyl)‐5‐methylthiophen‐2‐yl)‐5,6‐difluoro‐2‐propyl‐2H‐benzo[d][1,2,3]triazole (PTFB‐O) polymer donor with the 3,9‐bis(2‐methylene‐(3‐(1,1‐dicyanomethylene)‐indanone))‐5,5,11,11‐tetrakis(5‐hexylthienyl)‐dithieno[2,3‐d:2′,3′‐d′]‐s‐indaceno[1,2‐b:5,6‐b′]dithiophene (ITIC‐Th) and 2,2′‐((2Z,2′Z)‐(((4,4,9,9‐tetrakis(5‐hexylthiophen‐2‐yl)‐4,9‐dihydro‐s‐indaceno[1,2‐b:5,6‐b′]dithiophene‐2,7‐diyl)bis(4‐octylthiophene‐5,2‐diyl))‐bis(methanylylidene))bis(3‐oxo‐2,3‐dihydro‐1H‐indene‐2,1‐diylidene))‐dimalononitrile (IEIC‐Th) acceptors. The intermolecular packings and extent of mixing between the polymer donor and the acceptor in both binary blends are found to be similar, which is consistent with the well‐mixed nature of the ITIC‐Th:IEIC‐Th phase and the quasi‐linear evolution of open‐circuit voltage as a function of ITIC‐Th concentration in the PTFB‐O:ITIC‐Th:IEIC‐Th ternary blend. The intermolecular packing patterns and electron‐transfer rates among the acceptors are explored to rationalize the higher electron mobility found in the PTFB‐O:ITIC‐Th blend. The energetic distribution of the charge‐transfer electronic states and non‐radiative recombination rates are also evaluated to understand the difference in voltage losses between the binary blends.
