Published: March 2020

Abstract
The hydrothermal reaction of Zn(II) nitrate hydrate with 5-(pyridin-4-yl)isophthalic acid (H2L) yields the complex [Zn2(L)2(H2O)2] · 2(H2O) (1), which has been characterized by single crystal X-ray diffraction, IR spectroscopic, elemental, and thermogravimetric analyses. Complex 1 exhibits a 3-nodal (3,6)-connected 2D net structure with (4.62)2(42.610.83)(63)4 topology. Its luminescence property was investigated, but the results show that the coordination to the zinc atom has no significant effect on the emission of the ligand.

Abstract
Agar-Newman, DJ, Tsai, MC, and Klimstra, M. The validity of applying a simple three-factor computational model to calculate force, power, and speed using hexagonal bar jumps. J Strength Cond Res 36(8): 2108–2114, 2022—The development of athlete specific force–speed profiles can be accomplished through testing ballistic movements, enabling athlete comparisons and to direct training interventions. However, field-based assessments relying on the squat jump or countermovement jump may lack specificity for some sports or be contraindicated for some athletes. Therefore, the purpose of this study was to assess the validity of a three-factor computational model using system mass, push-off distance, and jump height to calculate force, speed, and power for the hexagonal bar (hex-bar) jump. Twenty-one university varsity rowing athletes (12 females and 9 males, 20.40 ± 2.60 years, 78.56 ± 13.68 kg, 1.77 ± 0.08 m, and strength training history of 3.57 ± 2.69 years) were purposefully sampled. Testing consisted of jumps at loads starting at 28.55 kg and increasing by 10-kg increments to 78.55 kg or until technical failure occurred. Validity was assessed by comparing the three-factor computational model to the criterion force–time measures from a force plate. The results show force (mean bias = 85.38 N, SE = 5.41, 95% confidence limit 1,576.85–1,598.19), speed (mean bias = 0.00 m·s−1, SE =

, 95% confidence limit 0.72–0.72), and power (mean bias = 73.36 W, SE = 3.90, 95% confidence limit 1,166.61–1,181.97) can be computed using a three-factor computational model using the hex-bar jump. In conclusion, jump height from a hex-bar jump can be used with a simple three-factor computational model to calculate valid measures of force, speed, and power. This allows practitioners in the field to use a movement that may be more sport-specific or safe, to calculate kinetic and kinematic measures without encountering the issues of cost and portability associated with force plates.
Covalent Functionalization of Multi-Walled Carbon Nanotubes for Dispersion in Cement Pastes
Authors: Liu Hui , Wang Jianfeng , Cui Suping , Wang Jiachen 
Published: March 2020

Abstract
Covalent functionalization of multi-walled carbon nanotubes (MWCNTs) were obtained through acidification, γ-Methacryloxypropyl trimethoxy silane (KH-570) treatment, and free radical polymerization using methyl allyl polyethenoxy ether (HPEG). Fourier-transformed infrared spectroscope was employed to determine the composition and structural changes of MWCNTs after modification. The dispersion of MWCNTs modified by HPEG in water at pH∼13 was determined by UV-vis-NIR. In addition, the effects of modified MWCNTs on cement hydration were investigated to describe the dispersibility of MWCNTs in cement pastes indirectly. Results show that oxygen functional groups generated on the surface of MWCNTs after acidification and KH-570 grafted on acidified MWCNTs through ≡Si–O–C≡ before radical polymerization with HPEG. MWCNTs modified by HPEG exhibit better dispersibility than pristine MWCNTs in a simulated cement pastes environment prepared at pH∼13. The additions of functionalized MWCNTs (P3-S-MWCNTs) promote the hydration of cement pastes indicated from isothermal conduction calorimeter measurement and X-ray diffraction analysis. Scanning electron microscopy observation confirmed the good dispersibility of functionalized MWCNTs in cement pastes. The promoting effect on cement hydration of P3-S-MWCNTs may attribute to the well-dispersed MWCNTs. The dispersed MWCNTs can act as the nucleating agent for carbon-sulfur-hydrogen and carbon-hydrogen, thus promoting the hydration of cement.

AbstractThe Jianchang duck is mainly distributed in Southwest China, and has the characteristics of fast growth rate and strong abilities in lipid deposition in the liver. In order to investigate the effects of domestication process on formation of the unique characteristics of Jianchang duck, the whole genome of sixteen individuals and three pooling of Jianchang duck were re-sequenced, and genome data of 70 mallards and 83 domestic ducks from thirteen different places in China were obtained from NCBI. The population stratification and evolution analysis showed gene exchanges existed between the Jianchang and other domestic duck populations, as well as Jianchang ducks and mallards. Genomic comparison between mallards and Jianchang ducks showed genes, including CNTN1, CHRNA9, and SHANK2, which is involved in brain and nerve development, experienced strong positive selection in the process of Jianchang duck domestication. The genomic comparison between Jianchang and domestic duck populations showed that HSD17B12 and ESM1, which affect lipid metabolism, experienced strong positive selection during the domestication process. FST analysis among populations of Jianchang duck with different plumage colors indicated that MITF was related to the phenotype of a white feather, while MC1R was related to the phenotype of hemp feather. Our results provided a base for the domestication process of Jianchang duck and the genomic genes for unique traits.
Trends in Regionalization of Emergency Care for Common Pediatric Conditions
Authors: Cushing Anna M. , Bucholz Emily , Michelson Kenneth A. 
Published: March 2020

BACKGROUND:
For children who cannot be discharged from the emergency department, definitive care has become less frequent at most hospitals. It is uncertain whether this is true for common conditions that do not require specialty care. We sought to determine how the likelihood of definitive care has changed for 3 common pediatric conditions: asthma, croup, and gastroenteritis.

METHODS:
We used the Nationwide Emergency Department Sample database to study children &lt;18 years old presenting to emergency departments in the United States from 2008 to 2016 with a primary diagnosis of asthma, croup, or gastroenteritis, excluding critically ill patients. The primary outcome was referral rate: the number of patients transferred among all patients who could not be discharged. Analyses were stratified by quartile of annual pediatric volume. We used logistic regression to determine if changes over time in demographics or comorbidities could account for referral rate changes.

RESULTS:
Referral rates increased for each condition in all volume quartiles. Referral rates were greatest in the lowest pediatric volume quartile. Referral rates in the lowest pediatric volume quartile increased for asthma (13.6% per year; 95% confidence interval [CI] 5.6%–22.2%), croup (14.8% per year; 95% CI 2.6%–28.3%), and gastroenteritis (16.4% per year; 95% CI 3.5%–31.0%). Changes over time in patient age, sex, comorbidities, weekend presentation, payer mix, urban-rural location of presentation, or area income did not account for these findings.

CONCLUSIONS:
Increasing referral rates over time suggest decreasing provision of definitive care and regionalization of inpatient care for 3 common, generally straightforward conditions.

O artigo analisa o Projeto de Lei Complementar (PLP) n° 413/2014 que institui o Sistema Nacional de Educação (SNE) à luz de categorias teóricas do federalismo. O objetivo é contribuir com um programa de pesquisa mais amplo sobre os impactos da constituição de um novo arranjo institucional, neste caso o SNE, sobre os fundamentos e características do federalismo brasileiro. Metodologicamente, faz uma abordagem histórico-político-ideológico-legal, utilizando um esquema composto por uma parte descritiva, desenvolvida pelos autores a partir da proposta de Bucci (2016), na interseção do direito e políticas públicas, e de uma parte analítica, construída a partir de referencial teórico. As variáveis descritivas destacam a identificação da política pública, sua organização e o desenho jurídico-institucional. Sofreu acréscimo pelos autores da variável ideológica. A parte analítica do esquema elenca as variáveis próprias ao federalismo como distribuição de poder, graus de descentralização, distribuição de finanças, processos de flexibilidade e ajustes, sistema multiníveis e instituições representativas. Conclui-se que o conteúdo da PLP 413/2014 promove interferências políticas, legislativas e administrativas nas autonomias dos entes federados. São identificados estratégias, ações e procedimentos que podem limitar o pluralismo político e a diversidade de valores definidos constitucionalmente.

Published: March 2020

Purpose of the study. To evaluate the level of detail, the amount of visualized data and the levels of navigation systems of primary medical organizations.Materials and methods. The object of this study was 33 primary care medical organizations located on the territory of 7 constituent entities of the Russian Federation. The subject of the study was all the internal and external navigation elements of the MO. The assessment was based on the ALIDS checklist (version 1.0) of 72 indicators, united by five characteristics in general characteristics: architectural-planning and design solutions, transmitted information, levels and navigation elements. The “Levels” block was represented by 19 parameters with a separate assessment of the internal level (9 indicators), the intermediate level (5 indicators) and the external level (5 indicators) of navigation. For each criterion, a nominal dichotomous point score was set with the possibility, if necessary (doubt, clarification, question, etc.) of indicating an expert comment.Results. A full-time study of the navigation systems of 33 primary medical organizations found that the levels of intermediate and external visualization are not used enough. Unlike architectural and planning solutions, various levels of navigation are maximally represented in medical institutions of the Tyumen and Kaliningrad regions, Krasnoyarsk Territory. The lack of an external level of navigation contributes to the main losses of lean production: unnecessary movement, unnecessary transportation and expectations from patients and visitors. Among the objects of internal navigation, cabinets and safety signs are most often placed on the navigation elements. The maximum percentage of compliance among the intermediate navigation category has been established for the main entrances for visitors, including entrances for patients with limited mobility.Conclusion. The navigation system of a medical organization is an important part of the visualization system and one of the criteria for the quality of space. The qualimetry of navigation systems not only of medical organizations, but also of any other buildings and premises, is currently not conclusively presented. Using the author's ALIDS method of audit of navigation systems allows us to give a quantitative and qualitative assessment of the navigation elements used in medical institutions. While improving the navigation systems of existing medical organizations and designing/building new ones, especially with complex mixed or section planning, in order to reduce the main losses of lean manufacturing, it is necessary to create the most detailed and understandable general navigation schemes.

Published: March 2020

In
recent years there has been a rapid growth in the construction sector in order
to meet the need for housing with the increase in population. This growth led
to the rapid development of the cement industry. In the process of increasing
industrialization, biotechnological processes are becoming more important. The
most important alternative of the cement industry is the microbial
bio-calcification processes. In this process, cement-like structures are
produced by bacteria at room temperature conditions. Microbial
bio-calcification processes have attracted the interest of researchers
especially in the process of self-healing in recent years as an alternative and
nature-friendly solution to the cement processes that are being produced at
high temperatures. This study presents a comparative study for sand hardening
by microbial bio-calcification process. Different production surfaces was used
for sand hardening with Sporosarcina
pasteurii such as agar plates, filter paper and polyurethane support
materials. The effect of different CaCl2 concentrations (25 mM, 50
mM and 100 mM) and sand thickness (1mm, 5mm and 10 mm) was also tested. CaCO3
was determined by FTIR and measured by chemical analysis. In addition, the
hardness and integrity of the samples were observed. Agar and polyurethane
support materials were found to be more effective in terms of support material
for sand hardening. Increased thickness reduced the hardness and 50 mM CaCl2
concentration was found to be optimum for these types of processes. This study
shows the effects of sand hardness on innovative, environmentally friendly and biotechnological approach optimization.

Rastros de vanguarda em uma rua de mão única: caminhos possíveis em Walter Benjamin / Tracks of Avant-Guard in a One-Way Street: Possible Paths in Walter Benjamin
Authors: Lima Nathália Ananda Silva de 
Published: March 2020

Resumo: Ao elencar e organizar uma vasta coleção de textos fragmentários, que versam desde reflexões sobre suportes para o literário até o cotidiano dos alemães, Walter Benjamin revela em “Rua de mão única” (1928) uma possibilidade de aproximar sua proposta de escritura às estéticas de vanguarda do início do século XX. Desse modo, a presença da técnica de montagem permite entrever o rastro de elementos surrealistas, dadaístas e cubistas na constituição da obra. Assim, para ilustrar como tais artifícios ressoam em Benjamin, este trabalho apresentará contextualizações históricas de Nicolau Sevcenko e Francesco Careri e o estudo sobre técnicas de montagem de Willi Bolle junto a fragmentos da obra do pensador alemão.Palavras-chave: Walter Benjamin; vanguarda; Rua de mão única.Abstract: By cataloguing and organizing a vast collection of fragmentary texts, which cover aspects from his reflection about supports to the literary text to the German quotidian, Walter Benjamin revels, in “Rua de mão única” (1928), the possibility of approaching his proposal of writing to the Avant-guard aesthetics of the beginning of the 20th century. This way, the presence of the montage technique allows us to glimpse the tracks of surrealist, dadaist and cubist elements in the constitution of the work. Thus, to illustrate how such artifices resonate in Benjamin, this work presents the historical contextualization by Nicolau Sevcenko and Francesco Careri and the study about techniques of montage by Willi Bolle, together with fragments of the German thinker’s work.Keywords: Walter Benjamin; avant-guard; one-way street.
