Authors: Liu Shuailing , Ma Guoyuan , Xu Shuxue , Li Fuping , Hang Chenzhe
Published: April 2020

The improvement performance of refrigerating dehumidification system was theoretically discusses based on a dehumidification model. The influence of evaporator inlet wind speed, dry bulb temperature and relative humidity on dehumidification were analysed by the model. The results show that, when inlet air temperature and humidity were kept constant, the dehumidification capacity increased first and then decreased with increase of the wind speed. When the moisture content and the wind speed of the inlet air were kept constant, the dehumidification capacity gradually decreased with increase of the inlet air dry bulb temperature. The inlet air dry bulb temperature was between 21-36?C and the relative humidity was between 40% and 85%, the difference between the inlet air wet bulb temperature and the evaporation temperature at the optimum COP was about 10?C. There was a nearly linear relationship between the corresponding evaporation temperature at the optimal COP and the evaporation temperature with the maximum dehumidification capacity, compared with the test value, the error was less than 10%.

OBJECTIVE

To describe celiac disease (CD) screening rates and glycemic outcomes of a gluten-free diet (GFD) in patients with type 1 diabetes who are asymptomatic for CD.

RESEARCH DESIGN AND METHODS

Asymptomatic patients (8–45 years) were screened for CD. Biopsy-confirmed CD participants were randomized to GFD or gluten-containing diet (GCD) to assess changes in HbA1c and continuous glucose monitoring over 12 months.

RESULTS

Adults had higher CD-seropositivity rates than children (6.8% [95% CI 4.9–8.2%, N = 1,298] vs. 4.7% [95% CI 3.4–5.9%, N = 1,089], P = 0.035) with lower rates of prior CD screening (6.9% vs. 44.2%, P < 0.0001). Fifty-one participants were randomized to a GFD (N = 27) or GCD (N = 24). No HbA1c differences were seen between the groups (+0.14%, 1.5 mmol/mol; 95% CI −0.79 to 1.08; P = 0.76), although greater postprandial glucose increases (4-h +1.5 mmol/L; 95% CI 0.4–2.7; P = 0.014) emerged with a GFD.

CONCLUSIONS

CD is frequently observed in asymptomatic patients with type 1 diabetes, and clinical vigilance is warranted with initiation of a GFD.
Using the BRAVO Risk Engine to Predict Cardiovascular Outcomes in Clinical Trials With Sodium–Glucose Transporter 2 Inhibitors
Authors: Shao Hui , Shi Lizheng , Fonseca Vivian A.
Published: April 2020

OBJECTIVE

This study evaluated the ability of the Building, Relating, Assessing, and Validating Outcomes (BRAVO) risk engine to accurately project cardiovascular outcomes in three major clinical trials—BI 10773 (Empagliflozin) Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME), Canagliflozin Cardiovascular Assessment Study (CANVAS), and Dapagliflozin Effect on Cardiovascular Events–Thrombolysis in Myocardial Infarction (DECLARE-TIMI 58) trial—on sodium–glucose cotransporter 2 inhibitors (SGLT2is) to treat patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS

Baseline data from the publications of the three trials were obtained and entered into the BRAVO model to predict cardiovascular outcomes. Projected benefits of reducing risk factors of interest (A1C, systolic blood pressure [SBP], LDL, or BMI) on cardiovascular events were evaluated, and simulated outcomes were compared with those observed in each trial.

RESULTS

BRAVO achieved the best prediction accuracy when simulating outcomes of the CANVAS and DECLARE-TIMI 58 trials. For EMPA-REG OUTCOME, a mild bias was observed (∼20%) in the prediction of mortality and angina. The effect of risk reduction on outcomes in treatment versus placebo groups predicted by the BRAVO model strongly correlated with the observed effect of risk reduction on the trial outcomes as published. Finally, the BRAVO engine revealed that most of the clinical benefits associated with SGLT2i treatment are through A1C control, although reductions in SBP and BMI explain a proportion of the observed decline in cardiovascular events.

CONCLUSIONS

The BRAVO risk engine was effective in predicting the benefits of SGLT2is on cardiovascular health through improvements in commonly measured risk factors, including A1C, SBP, and BMI. Since these benefits are individually small, the use of the complex, dynamic BRAVO model is ideal to explain the cardiovascular outcome trial results.
Theoretical study of influence of electromagnetic stirring on transport phenomena in wire feed laser beam welding
Authors: Meng Xiangmeng , Artinov Antoni , Bachmann Marcel , Rethmeier Michael
Published: April 2020

The additional element from the filler wire in the laser beam welding is usually distributed inhomogeneously in the final weld due to the high solidification rate of weld pool. It has been found that the electromagnetic stirring produced by an external oscillating magnetic field can enhance the material mixing in the weld pool to achieve a more uniform element distribution. However, the magnetic field has a highly nonlinear and multicoupled interaction with the weld pool behavior, which makes the quantitative explanation of the physical mechanism difficult. In this study, the effect of electromagnetic stirring on the transport phenomena in the wire feed laser beam welding is investigated by a numerical modeling. A 3D transient multiphysical model considering the magnetohydrodynamics, heat transfer, fluid flow, keyhole dynamics, and element transport is developed. The multiple reflections and the Fresnel absorption of the laser on the keyhole wall are calculated using the ray tracing method. The numerical results show that a Lorentz force produced by the oscillating magnetic field and its induced eddy current gives significant influence on the transport phenomena in the molten pool. The forward and downward flow is enhanced by the electromagnetic stirring, which homogenizes the distribution of the additional elements from a nickel-based filler wire in a steel weld pool. The numerical results show a good agreement with the high-speed images of the molten pool, the fusion line from the optical micrograph, and the element distribution from the energy dispersive x-ray spectroscopy. This work provides a physical base for the electromagnetic-controlled laser beam welding and some guidance for the selection of electromagnetic parameters.

La aplicación de la teoría de los juegos, en especial de “La batalla de los sexos” facilita el análisis del proceso de negociación y los motivos por los que se producen los resultados. Se ha podido verificar que los actores se integran formando constelaciones, en las cuales, dependiendo de las circunstancias históricas, el factor común de unión puede variar. En algunos casos la unión es de tipo político, en otros la unión es por características de las provincias (chicas o grandes), actividades económicas relevantes en las provincias (por ej. el petróleo o la actividad vitivinícola), y en otras la unión está basada en la resistencia a la propuesta.

Ethos crítico y a priori histórico de una experiencia posible. Contribución filosófica a la noción de crítica desde una ontología del presente
Authors: Vignale Silvana
Published: April 2020

Tal como lo anticipa el título de este dossier, la crítica se concibe como el trabajo sobre los límites y las posibilidades de un determinado objeto. Nuestra contribución se ocupará de atender el carácter de la crítica desde una perspectiva filosófica, más específicamente, desde el trabajo filosófico de una ontología del presente. Para eso, la abordaremos en un primer momento como una metódica de la investigación en las ciencias sociales y humanas, tomando distancia del disciplinamiento que busca reducir el trabajo teórico a metodologías prefabricadas. El posicionamiento crítico involucra al investigador en la realidad que investiga, e historiza su emergencia junto al objeto de estudio, con atención a las implicancias entre saber y poder, en el marco de lo que podemos denominar una epistemología crítica.

Published: April 2020

The development of coastal zones throughout the world has resulted in changes in the order of the mangrove ecosystem, therefore, planting activities are carried out in various regions. The study of the testing and determination of gastropod species as bioindicators in the mangrove reforestation area was carried out in the Seribu Islands. This research aims to determine how suitable the gastropod species are used as bioindicators in assessing the success of mangrove reforestation, especially in the Seribu Islands. Collection of gastropod species is done by making line transects and plots drawn from the reference point (outermost mangrove stands) and perpendicular to the coastline to the mainland. Line transects are made of plots of size 10 x 10 m and in the size of 10 x 10 m a small plot of 1 x 1 m is made. Furthermore, testing is carried out with several criteria and analyzed using multivariate Principal Component Analysis (PCA) statistics. The results of the study show that the species Littoraria scabra has met all the specified testing criteria. Then L. scabra also has the highest eigenvalue compared to the other species, making it suitable to be used as a bioindicator species in assessing the success of the Seribu Islands mangrove reforestation.
Analyzing the liabilities and stockholders' equity of the world's leading public oil and gas corporations
Authors: Shimko O.V.
Published: April 2020

Subject. The article investigates liabilities and equity of leading public oil and gas companies from 2006 to 2018. Objectives. The focus is on determining the current values of the main components of liabilities and equity of leading public oil and gas companies, identifying the key trends over the studied period and factors that led to the changes. Methods. The paper employs methods of comparative, financial, and economic analysis, generalization of official annual reports on financial and business operations of the said corporations. Results. Based on the results of the comprehensive analysis of balance sheets of 25 oil and gas companies, I established movements in the size and structure of liabilities and equity in the public sector of the industry and the main factors that contributed to the changes. Conclusions. Over the studied period, I revealed an increase in the balance sheet valuation of liabilities and equity of most of leading public oil and gas companies, notwithstanding a noticeable decrease in their value after the industry crisis. The components of liabilities and equity remained approximately equal, but the transformation in the ratio between the components occurred within the indicators themselves. The long-term component started prevailing in the structure of liabilities. It was driven by growing total debt, which almost equaled the value of accounts payable. As a result, the total debt became the dominant component of long-term liabilities, and accounts payable retained key positions only in the short-term component.

Mengkaji Ulang Gagasan Pengadilan Khusus Pemilihan Umum di Indonesia
Authors: Gusman Delfina
Published: April 2020

General elections are a means of democracy to elect leaders who will carry out the wheels of government for a certain period of time, through legitimate power transfer procedures by involving public participation. Elections are the crystallization of popular sovereignty in procedural mechanisms. But often in the implementation of procedural democracy this is followed by fraudulent actions that tarnish the true nature of democracy (substantial democracy). Therefore, we need a law enforcement agency for every action that can damage the essential meaning of democracy and elections in Indonesia. The idea of a special court emerged as an alternative to electoral dispute resolution in the study of Indonesian constitutional law, however this idea needs to be discussed in more depth from various aspects to see its relevance to the Indonesian constitutional system, given that long before there was the idea of a special election court, Indonesia already had a number of institutions that given a mandate and authority to resolve disputes related to elections. This paper uses normative juridical methods in its study and is supported by secondary data in the form of primary, secondary and tertiary legal materials. The analysis used is qualitative analysis. The results of the study revealed that the idea of establishing an electoral special court was the idea of state administration which emerged amidst the struggle to substantially improve the quality of democracy. However, in its formation, it does not only require clear legal politics, but also requires a holistic study of the mechanism and flow of resolution and models of electoral dispute resolution. The parameter that needs to be used in examining the idea of a special electoral court is to measure the extent and importance of elections for Indonesian democracy. because the more important the meaning of the election is the presence of special election court more worthy of consideration

The Indigenous Decade in Review
Authors: Zuni Cruz Christine
Published: April 2020

This Article considers the decade, 2010 to 2019, in respect to indigenous peoples in the United States. The degree of invisibility of indigenous peoples, in spite of the existence of 574 federally recognized tribes with political status, is a central issue in major cases and events of the decade. Land and environment, social concerns, and collective identity are the three areas through which this Article considers the decade. The Declaration on the Rights of Indigenous Peoples, endorsed in 2010, sets a measure for the nation-state’s engagement with indigenous peoples possessed of self-determination. The criticality of a new place in the American consciousness for the political status of indigenous peoples in the United States going forward is a feature of the decade.
Erasing Race
Authors: Green Llezlie L.
Published: April 2020

Low-wage workers frequently experience exploitation, including wage theft, at the intersection of their racial identities and their economic vulnerabilities. Scholars, however, rarely consider the role of wage and hour exploitation in broader racial subordination frameworks. This Essay considers the narratives that have informed the detachment of racial justice from the worker exploitation narrative and the distancing of economic justice from the civil rights narrative. It then contends that social movements, like the Fight for $15, can disrupt narrow understandings of low-wage worker exploitation and proffer more nuanced narratives that connect race, economic justice, and civil rights to a broader anti-subordination campaign that can more effectively protect the most vulnerable workers.

Neste artigo propomos, por meio de revisão bibliográfica, uma reflexão teórica sobre as transformações do capitalismo e a maneira como a ética protestante incorporou o espírito capitalista na sociedade de hiperconsumo. Constatamos que na contemporaneidade a vida cotidiana é convertida em uma aventura competitiva onde o apelo a autonomia e ao governo de si são competências essenciais para se obter sucesso. Isso dá origem à figura do indivíduo conquistador e seu correlato, o indivíduo incerto. É nesta lacuna entre o ser e o desejo ser que a religião atua.

As tetrazines are important tools to the field of bioorthogonal chemistry, there is a need for new approaches to synthesize unsymmetrical and 3-monosubstituted tetrazines. Described here is a general, one-pot method for converting (3methyloxetan-3-yl)methyl carboxylic esters into 3thiomethyltetrazines. These versatile intermediates were applied as a platform for the synthesis of unsymmetrical tetrazines via Pdcatalyzed cross-coupling and in the first example of catalytic thioether reduction to access monosubstituted tetrazines. The method enables the development of new tetrazines possessing a favorable combination of kinetics, small size and hydrophilicity. The chemistry was applied to a broad range of aliphatic and aromatic ester precursors and to the synthesis of heterocycles including BODIPY fluorophores and biotin. In addition, a series of tetrazine probes for monoacylglycerol lipase (MAGL) were synthesized and the most reactive one was applied in labeling of endogenous MAGL in live cells

Many diseases are associated with the dysregulated activity of enzymes, such as matrix metalloproteinases (MMPs). This dysregulation can be leveraged in drug delivery to achieve disease- or site-specific cargo release. Self-assembled polymeric nanoparticles are versatile drug carrier materials due to the accessible diversity of polymer chemistry. However, efficient loading of sensitive cargo, such as proteins, and introducing functional enzyme-responsive behaviour remain challenging. Herein, peptide-crosslinked, temperature-sensitive nanogels for protein delivery were designed to respond to MMP-7, which is overexpressed in many pathologies including cancer and inflammatory diseases. The incorporation of N-cyclopropylacrylamide (NCPAM) into N-isopropylacrylamide (NIPAM)-based copolymers enabled us to tune the polymer lower critical solution temperature from 33 to 44 °C, allowing the encapsulation of protein cargo and nanogel-crosslinking at slightly elevated temperatures. This approach resulted in nanogels that were held together by MMP-sensitive peptides for enzyme-specific protein delivery. We employed a combination of cryogenic transmission electron microscopy (cryo-TEM), dynamic light scattering (DLS), small angle neutron scattering (SANS), and fluorescence correlation spectroscopy (FCS) to precisely decipher the morphology, self-assembly mechanism, enzyme-responsiveness, and model protein loading/release properties of our nanogel platform. Simple variation of the peptide linker sequence and combining multiple different crosslinkers will enable us to adjust our platform to target specific diseases in the future.

Half-Heusler compounds with a valence electron count of 18, including ZrNiSn, ZrCoSb, and NbFeSb, are good thermoelec-tric materials owing to favourable electronic structures. Previous computational studies had predicted a high electrical power factor in another half-Heusler compound NbCoSn, but it has not been extensively investigated experimentally. Herein, the synthesis, structural characterization, and thermoelectric properties of the heavy-element Pt-doped NbCoSn compounds are reported. Pt is found to be an effective dopant enabling the optimization of electrical power factor, simul-taneously leading to a strong point defect scattering of phonons, and thereby suppressing the lattice thermal conductivity. Annealing significantly improves the carrier mobility, which is ascribed to the decreased grain boundary scattering. As a result, a maximum power factor of ~3.4 mWm-1K-2 is obtained at 600 K. In conjunction with the reduced lattice thermal conductivity, a maximum figure of merit zT of ~0.6 is achieved at 773 K for the post-annealed NbCo0.95Pt0.05Sn, an increase of 100% compared to the undoped NbCoSn. This work highlights the important roles of the doping element and micro-structure on the thermoelectric properties of half-Heusler compounds

Philosophical interpretation to the history in Nosherwan Mustafa’s perspective
Authors: Maulud Azad Ali , Mustafa Aras Abdulrahman , Muhammed Qadir Muhammed
Published: April 2020

Noshrwan Mustafa Emin ( 1944 -2017), commonly known as Noshirwan Mustafa, was a prominent Kurdish political figure and Peshmerga commander. He played an important role in the political life of southern Kurdistan as a Peshmarga commander and political activist. Therefore, the majority of Kurdish people may know him as a politician rather than as an author or historian. Pondering upon Noshrwan Mustafa’s history related writings, indicates that his contributions in that area is as significant as his political career. This research deals with a side of     Noshrwan Mustaf’s history writing style, which is " philosophical interpretation to the history in Noshrwan mustaf’s perspective". It appears that Noshrwan Mustafa was aware of the philosophical iterepretations. They could easily be noticed in his historical books. He, however, did not rely on only one philosophical school of thought to analyze historical events. He appears to have taken into account a plethora of philosophical views to analyze history.

In the current empirical research, the researchers aimed to prepare a scale and program on rapid reading and its impact on understanding and increasing the number of words as it went (Tony Buzan, 2011 - 2018). The program was based on a sample consisting of (14) equal female students in terms of age, sex, social status and level of education, as one experimental group of students of the internal section (18) at the University of Salahaddin - Erbil. The importance of the current empirical research is that reading fast teaches students to learn new ways of reading and understanding and increasing the number of words, and left the previous misconceptions in reading and understanding, which we learned from childhood in schools, where it was an obstacle to reading fast and understanding and increase the number of words and benefit from the effort and time as well. The accuracy of the visual reliability and the stability of the method test and re-test were verified. The apparent of the visual reliability was 100% and the stability coefficient was 91%. The pre-test was carried out on the experimental group and the program was applied to them and then the post-test was performed on them. Statistical analysis of the social sciences (Spss) showed the results: 1. Prepare a rapid reading program 2. There is a statistically significant difference between the arithmetic mean value of the pre- test and the post-test, in favor for the post-test in degree of freedom (26) at the level of statistical significance (0.001) This means that the independent variable (Quick Reading Program) has an effective effect on the dependent variables (understanding and increasing the number of words). In the light of the results, the researchers presented some recommendations and suggestions.

Published: April 2020

This paper tackles nonverbal communication cues among refugees. It is widely believed that nonverbal communication is one of the most effective types of communication to enhance better human understanding and cooperation. Besides, interpretation and comprehension of this type of communication are crucial among diverse nations, cultures, and ethnic groups. On the other hand, the number of refugees has increased because of several factors, mainly including armed political conflicts in Middle-Eastern countries. Thus, they face political, economic, social, and/or psychological threats. Besides, they encounter other challenging difficulties in verbal and nonverbal communication. Therefore, communication enhancement has become essential and crucial to treat refugees through more proactive nonverbal communication strategies. The study targets real people in Sulaimani Governorate refugee camps, Kurdistan Region of Iraq. It investigates the types of nonverbal cues in the sociopragmatic refugeeism context. It initiates by some definitions of sociopragmatics and nonverbal communication and its cues categorization. In addition, it extends to explain the impact of sociopragmatic variables on the communicative types of nonverbal cues.
Lectura de Marx
Authors: Duek Celia , Inda Graciela
Published: April 2020

A pesar de que toda la teoría de Marx tiene por centro y corazón la lucha de clases, Marx no formuló con la sistematicidad que se ocupó de otros temas una «Teoría» de las clases sociales, en tanto sistema de conceptos rigurosamente definidos. El propósito de este artículo es recomponer algunas cuestiones centrales en la definición marxista de las clases sociales, así como demostrar la enorme significación teórica del descubrimiento de Marx. Se pretende por último señalar la distancia respecto de toda concepción subjetivista, economicista, voluntarista, distributiva y socioprofesional de las clases.
