Authors: Zhang Yawei , Ren Guanhua , Zhou Xiang , Zhou Lu , Ta La , Su Xiaoqiang
Published: November 2021

Terahertz (THz) technology is particularly suitable for non-destructive detection of porcelain sherd due to the unique properties of non-ionizing, high penetration, and broad-spectrum. In this paper, we investigated the reflection characteristics of the pigments and sediments for red and green porcelain sherd of Bayi Kiln made in Shanxi province during the Jin Dynasty by terahertz time-domain spectroscopy (THz-TDS), obtaining the spectral responses of different components. Furthermore, Raman spectroscopy was used as a complementary technique to complete the qualitative analysis of the pigments and sediments. In addition, the reflective THz imaging was performed to visualize the pigments and sediments in different regions of the porcelain sherd, realizing the visual detection of the pattern on the surface of the porcelain sherd. These results show that THz-TDS and THz-imaging can serve as effective tools for the detection and analysis of ancient Chinese porcelain.

Published: November 2021

Based on Burton−Cabrera−Frank theory and the step-edge segregation model, we analyzed the reported difference in the sheet concentration of doped magnesium under naturally formed surface stripes on homo-epitaxially grown layers on a freestanding GaN substrate misoriented from a c-plane by 0.3°. By assuming the step height being equal to the peak-to-valley height of the surface stripes, we considered the growth steps on gently and sharply sloped surfaces to be supplied, respectively, from mixed dislocations and the misorientation from the c-plane. The step-velocity dependence of the magnesium concentration was reproduced with the reported magnesium diffusivity of 3 × 10−14 cm2 s−1.

Published: November 2021

This paper discusses the effectiveness of supervision carried out by madrasa supervisors in the Ministry of Religion of the Kepulauan Riau Province from a contemporary perspective. The problem is that in the Kepulauan Riau Province there is an imbalance between the number of madrasas and the number of supervisors needed. One thing that is interesting is how the management of educational supervision is carried out while the number of supervisors has not been reached. This research is categorized as field research with qualitative research methods. The data were taken from direct observations at the research location, namely at the Ministry of Religion of the Kepulauan Riau Province and in madrasas. The nature of this research is descriptive-analytical research which aims to accurately describe and analyze the supervision carried out by madrasa supervisors at the Ministry of Religion of the Kepulauan Riau Province. From the data collected, it was found that those who act as madrasa supervisors within the Ministry of Religion of the Kepulauan Riau Province are mostly madrasa heads. Therefore, in addition to serving as a leader in his madrasa, the madrasa principal is also expected to be able to understand and be able to carry out supervision properly. With such conditions, adequate competence is needed that must be possessed by a madrasa supervisor who doubles as the head of the madrasa. So that the supervision carried out can run effectively.

Published: November 2021

Introducción: el Síndrome Metabólico (SM) se caracteriza por obesidad, hiperglucemia o diabetes, hipertensión arterial y dislipidemia. La presencia de este síndrome incrementa el riesgo de enfermedades cardiovasculares, con el consecuente aumento de la mortalidad.

Objetivo: determinar la frecuencia del SM y sus componentes en los trabajadores de un hospital de III nivel de atención, utilizando tanto los criterios de la Federación Internacional de Diabetes (IDF) como la definición unificada (armonizada).

Metodología: estudio descriptivo transversal realizado en personal del Hospital Universitario de La Samaritana de Bogotá. Para 1.140 trabajadores, considerando prevalencia de 26% e IC 95%, se calculó una muestra de 235 sujetos, a quienes se les realizó encuesta personalizada, exámenes paraclínicos (perfil lipídico y glucemia) y toma de medidas antropométricas (peso, talla, perímetro de cintura y tensión arterial). Para el análisis, la muestra se distribuyó en 2 grupos: Administrativo (sin formación específica en el área de salud) y Salud (con dicha formación), para determinar la posible relación entre prevalencia de SM y conocimiento previo sobre este síndrome.

Resultados: se obtuvo información completa de 209 trabajadores: 83 (39,7%) en Administrativo y 126 (60,3%) en Salud; la mayoría (50,7%) con edad entre 35 y 50 años, y con predominio de mujeres (72,7%). La frecuencia de SM fue 28,7% por criterios unificados (armonizados) y 26,3% por IDF; utilizando los primeros la frecuencia fue 30,1% en el grupo Administrativo y 27,8% en el grupo Salud, diferencia sin significancia estadística. El SM fue más frecuente en mayores de 50 años (46,4%) y en los niveles educativos Secundaria (42,9%) y Técnico (32,5%). El análisis de frecuencia según conocimiento previo sobre SM y sus componentes no mostró diferencia estadísticamente significativa.

Conclusiones: la frecuencia de SM en trabajadores de este hospital universitario es tan alta como la reportada para la población general. Los datos sugieren que aunque el personal de salud posee conocimiento básico sobre el SM no toma acciones eficaces para evitarlo.

Introducción: la falla cardiaca (FC) es una de las principales causas de morbimortalidad a nivel mundial, la cual ha experimentado aumento gradual de su incidencia sin variación importante en su desenlace en las dos últimas décadas. En Colombia muy pocos estudios evalúan factores asociados a mortalidad por falla cardiaca.

Métodos: estudio de cohorte prospectivo en el que se incluyeron pacientes con diagnóstico de falla cardiaca descompensada al momento del ingreso a urgencias, entre febrero de 2010 y marzo de 2013. Se calculó el tamaño de muestra y se realizó un análisis multivariado para la evaluación de los factores de riesgo asociados a mortalidad intrahospitalaria y a 30 días.

Resultados: se incluyeron 462 pacientes. La mortalidad hospitalaria fue de 8.9% y a 30 días de 13.8%, en el modelo multivariado para el desenlace mortalidad intrahospitalaria se observó que la única variable con significancia estadística fue el BUN ≥43 mg/dL (OR, 3.45 [IC 95% 1.54-7.74], p= 0.003). Para la mortalidad a 30 días, la estancia hospitalaria >5 días (OR, 2.23 [IC 95% 1.204.12], p= 0.011), el BUN ≥43 mg/dL (OR, 2.55 [IC 95% 1.31-4.94], p= 0.005) y el NT-proBNP ≥ 4630 pg/dL (OR, 2.47 [IC 95% 1.30-4.70], p= 0.006).

Conclusiones: la mortalidad intrahospitalaria de los pacientes con falla cardiaca descompensada en la población evaluada fue alta. En los análisis multivariados, se encontró que el BUN ≥ 43 mg/dL fue el único factor de riesgo independiente asociado a mortalidad intrahospitalaria; mientras que la mortalidad a 30 días se relacionó además con el NT-proBNP y la estancia hospitalaria superior a cinco días

Objective: To investigate the clinical characteristics of preterm infants with different severities of bronchopulmonary dysplasia (BPD) and disclose the high-risk factors of exacerbating BPD. Methods: Collection of clinical data of 91 preterm infants admitted to the NICU and diagnosed with BPD, categorized in groups according to the disease severity: 41 mild cases,, 24 moderate cases, and 26 severe cases. Comparison and analysis of perinatal risk factors, treatment, complications and prognosis of the infants with different severity degrees. Results: The severe group had a higher proportion of infants with congenital heart disease (CHD) higher than the moderate group (P < 0.05), and a higher ratio of pneumonia and mechanical ventilation (MV) = seven days than the mild group (P < 0.05). The severe group also presented higher reintubation incidence than both the mild and moderate groups (P < 0.05). The groups presented different (P < 0.05) incidence rates of hemodynamically significant patent ductus arteriosus (hsPDA) . Ridit analysis suggested that the premature infants (PIs) with hsPDA, multiple microbial pulmonary infections, or Klebsiella pneumoniae pneumonia had more severe illness. Conclusion: CHD, hsPDA, MV = seven days, reintubation, pneumonia, especially multiple microbial pulmonary infections, and Klebsiella pneumoniae pneumonia are correlated with the severity of BPD and can be used as BPD progression predictor.

Published: November 2021

Objective: To assess the frequency and severity of 24-hour respiratory symptoms according to COPD GOLD-ABCD classification (2017-version), the distribution of the patients with COPD into GOLD categories using mMRC (=2) or CAT (=10) scores, and agreement between these cut-off points. Methods: In this cross-sectional study (LASSYC study), 24-hour day respiratory symptoms were assessed by the Evaluating Respiratory Symptoms in COPD (E-RS) questionnaire, Nighttime Symptoms of COPD Instrument (NiSCI), Early Morning Symptoms of COPD Instrument (EMSCI), CAT and mMRC scores. Results: Among the 734 patients with COPD, 61% were male, age 69.6±8.7 years, FEV1% post-BD 49.1±17.5%, mMRC 1.8±1.0 and CAT 15.3±.8.1. By mMRC 33.7% were group-A, 29.2% group-B, 10.2% group-C and 26.9% group-D. By CAT 22.3% were group-A, 41% group-B, 4.8% group-C and 31.9% group-D. Using the mMRC the severity of E-RS, NiSCI and EMSCI scores increased from group A to D. Using the CAT, the groups B and D had the higher scores. Agreement between mMRC and CAT was 89.5% (Kappa statistics=75.7%). For mMRC score of 2, CAT score of =11 showed the maximum Youden's index (1.34). For mMRC score of 1, CAT score of =9 and =10 showed the maximum Youden's index (1.48). Conclusion: GOLD COPD classification by CAT seems to better discriminate 24-hour symptoms. Results do not support the equivalent use of CAT=10 and mMRC=2 for assessing symptoms.

Chayote (Sechium edule (Jacq.) Swartz) and kohlrabi (Brassica oleracea var gongylodes L.) are medicinal plants widely distributed in Thailand. Several traditional medicines usually contain these extracts due to their pharmaceutical activities. However, appropriate technologies that are used for protection, stabilization, and slow release of plant extracts are a lot desired in terms of food application. In this study, chayote and kohlrabi extracts were encapsulated by several kinds of wall materials (maltodextrin, and the combination of maltodextrin and gum arabic or alginate) and drying methods (freeze-drying and tray-drying techniques). Thus, the objective of this research was to determine morphological and physicochemical properties, wall materials releasing, and antioxidant activity of encapsulated chayote and kohlrabi extracts powder. The morphology of all encapsulated chayote and kohlrabi extracts powder showed irregular spherical shape, monodispersity, and smooth surface. The encapsulated chayote and kohlrabi extracts powder with tray-drying technique tend to have more darkness and redness in color than the freeze-drying technique. Wall material releasing was expressed in glucose liberation of encapsulated extracts powder after amylolytic enzyme digestion. Encapsulation using maltodextrin as wall material provided higher wall material releasing than the other samples. After digestion analysis, the digested residues were examined for antioxidant activity. The results showed that the combination of maltodextrin and alginate for both freeze-drying and tray-drying techniques provided higher antioxidant activity after 60 and 120 min of digestion. Thus, the combination of maltodextrin and alginate, and drying with the freeze-drying technique was the best treatment in this experiment. This data can lead to a better understanding of wall materials types and releasing characteristics, which are used to control bioactive compounds liberation in the gastrointestinal tract.

Published: November 2021

As in other countries in Central and West Asia, most of Kazakhstan's power plants have reached their potential as they were built mainly during the Soviet era. In this regard, it is important today to optimize coal consumption processes, introduce new environmentally friendly technologies and reduce emissions. And it is impossible without conducting detailed studies of the combustion of fuels in the combustion chambers of energy devices. It can provide complete information about the nature of complex processes of heat and mass transfer without special financial, time and labor costs. The existing models of the formation and destruction of nitrogen-containing substances NOx do not have a universal nature of use, since the fuel and combustion conditions are different. In this regard, the proposed work considered two models that are widely used. The aim of this work is to select a model that actually can describe the processes of dioxin formation in the combustion chamber of a real CHP boiler when high ash content coal is burned in it. The results of the simulation were verified with the data of field experiments, which allows an objective conclusion to be made. The obtained research data and the method of applying the selected optimal kinetic scheme of dioxin formation contribute to the development of new and optimization of existing measures to control environmental pollution
Price Volatility for Selected Agricultural Commodities in Ethiopia: Evidence from GARCH Models
Authors: Dinku Tirngo , Gardachw Worku , Adeleye Ngozi
Published: November 2021

This study models the volatility of returns for selected agricultural commodity prices in Ethiopia using the generalized autoregressive conditional heteroskedasticity (GARCH) approach. GARCH family models, specifically threshold GARCH and exponential GARCH were employed to analyze the time varying volatility of selected agricultural commodities prices from 2010 to 2021. The data analysis results revealed that, out of the GARCH specifications, the EGARCH model with the normal distributional assumption of residuals was a better fit model for the price volatility of “teff” and “red pepper” in which their return series reacted differently to the “good” and “bad” news. The study indicated the existence of a leverage effect, which implied that the “bad” news could have a larger effect on volatility than the “good” news of the same magnitude, and the asymmetric term was statistically significant.

This study aims to explore the perceptions of students of SD Karawaci Baru VIII Tangerang on the animated video The story of the Prophet Ibrahim (as) starting from the growing concern about animated video content and games that contain dangerous content or can damage the future of the nation's generation. This animated video produced by Al-Imran contains da'wah bil wisdom, da'wah bil mau'izah, and da'wah jidal bil ahsan in it. Therefore, the researchers tried to raise it through the theory of perception and the da'wah bil wasilah approach through the case study method with field observations and semi-structured interviews. The results of this study explain that the students of SD Karawaci Baru VIII Tangerang are supported by their parents and teachers in watching the animated video The Story of the Prophet Ibrahim as finding the meaning of wisdom, mau'izah hasanah, and jidal ahsan to be used as a means to build an umbrella or reaction filter against various information from outside that is not good or negative. Functionally (personal) and structurally (external environment) these students tend to like the story of the prophet Ibrahim, apart from their inner motives, as well as various needs that they don't get anywhere else or in their family. In addition, there is a desire to convey a call about the goodness, wisdom, and piety of Prophet Ibrahim which is suitable for learning these elementary school children. With order, creed, shari'ah, morals, and culture; animated videos become a small window to watch the various histories and stories of the noble prophets.
BLESSING OR CURSE? THE IMPACTS OF NON-AGRICULTURAL PART-TIME WORK OF THE LARGE FARMER HOUSEHOLDS ON AGRICULTURAL LABOR PRODUCTIVITY
Authors: Jiang Xin , Zhong Shihu , Huang Cancan , Guo Xiaoxin , Zhao Jingjing
Published: November 2021

This study analyzes the mechanism of coexistence of non-agricultural part-time work of farmer households and large-scale cultivation of cultivated land, and the effect of non-agricultural part-time work of the large farmer households on the agricultural labor productivity. Results indicate that non-agricultural part-time work of large farmer households promotes the agricultural labor productivity, particularly for those with higher non-agricultural incomes, younger age, higher education level and shorter distance between working places in urban sectors and rural residence. At the mean value of the samples, non-agricultural part-time work of the large farmer households will improve agricultural labor productivity by 27.1%. These results remain consistent after we experiment several robustness checks and the instrumental variable method. Further, it is worth stressing that non-agricultural part-time work inhibits the agricultural production for farmer households with labors less than three, while it exhibits positive effects for those with labors more than three. Finally, analysis of mechanism suggests that non-agricultural part-time work of large farmer households enhances the productivity via entering the agricultural association, increasing farm mechanization degree, and promoting the centralized production and farm management on the transferred farmland. It’s suggestive to maintain total area of the transferred farmland to avoid the reverse effects and then the optimal total cultivated area within the range of (100, 200) Mu. Policy implications of our work are discussed.

In addition, we present improved orbital and transit parameters by analyzing previously unused short-cadence K2 campaign 17 photometry and conduct a joint radial-velocity-transit fit to constrain the eccentricity at 0.41 ± 0.05. The addition of a transit observation by Spitzer also allows us to refine the orbital ephemeris in anticipation of further follow-up. Our mass determination, 6.26

The low H/He mass fraction, along with the old age of Wolf 503 (11 ± 2 Gyr), makes this sub-Neptune an opportune subject for testing theories of XUV-driven mass loss while the brightness of its host (J = 8.3 mag) makes it an attractive target for transmission spectroscopy.
Testing Models of Triggered Star Formation with Young Stellar Objects in Cepheus OB4

OB associations are home to newly formed massive stars, whose turbulent winds and ionizing flux create H ii regions rich with star formation. Studying the distribution and abundance of young stellar objects (YSOs) in these ionized bubbles can provide essential insight into the physical processes that shape their formation, allowing us to test competing models of star formation. In this work, we examined one such OB association, Cepheus OB4 (Cep OB4)—a well-suited region for studying YSOs due to its Galactic location, proximity, and geometry. We created a photometric catalog from Spitzer/Infrared Array Camera (IRAC) mosaics in bands 1 (3.6 μm) and 2 (4.5 μm). We supplemented the catalog with photometry from the Wide-field Infrared Survey Explorer, the Two Micron All Sky Survey, IRAC bands 3 (5.8 μm) and 4 (8.0 μm), MIPS 24 μm, and MMIRS near-infrared data. We used color–color selections to identify 821 YSOs, which we classified using the IR slope of the YSOs’ spectral energy distributions, finding 67 Class I, 103 flat spectrum, 569 Class II, and 82 Class III YSOs. We conducted a clustering analysis of the Cep OB4 YSOs and fit their spectral energy distributions. We found many young Class I objects distributed in the surrounding shell and pillars as well as a relative age gradient of unclustered sourcesin the bubble surrounding the OB association, with YSOs generally decreasing in age with distance from the central cluster. Both of these results indicate that the expansion of the H ii region may have triggered star formation in CepOB4.

bands covering an area of ∼18.′4 × 18.′4 toward the star-forming region Sh 2–190. This photometric data helped us to explore the nature of the variability of pre-main-sequence (PMS) stars. We have identified 85 PMS variables, i.e., 37 Class ii and 48 Class iii sources. Forty-five of the PMS variables show periodicity in their light curves. We show that the stars with thicker disks and envelopes rotate slower and exhibit larger photometric variations compared to their diskless counterparts. This result suggests that rotation of the PMS stars is regulated by the presence of circumstellar disks. We also found that the periods of the stars show a decreasing trend with increasing mass in the range of ∼0.5–2.5 M
⊙. Our result indicates that most of the variability in Class ii sources is ascribed to the presence of a thick disk, while the presence of cool spots on the stellar surface causes the brightness variation in Class iii sources. X-ray activities in the PMS stars were found to be at the saturation level reported for the main-sequence stars. The younger counterparts of the PMS variables show less X-ray activity, hinting at a less significant role of a stellar disk in X-ray generation.

Energetic neutral atom (ENA) models typically require post-processing routines to convert the distributions of plasma and H atoms into ENA maps. Here we investigate how two kinetic-MHD models of the heliosphere (the BU and Moscow models) manifest in modeled ENA maps using the same prescription and how they compare with Interstellar Boundary Explorer (IBEX) observations. Both MHD models treat the solar wind as a single-ion plasma for protons, which include thermal solar wind ions, pick-up ions (PUIs), and electrons. Our ENA prescription partitions the plasma into three distinct ion populations (thermal solar wind, PUIs transmitted and ones energized at the termination shock) and models the populations with Maxwellian distributions. Both kinetic-MHD heliospheric models produce a heliotail with heliosheath plasma that is organized by the solar magnetic field into two distinct north and south columns that become lobes of high mass flux flowing down the heliotail; however, in the BU model, the ISM flows between the two lobes at distances in the heliotail larger than 300 au. While our prescription produces similar ENA maps for the two different plasma and H atom solutions at the IBEX-Hi energy range (0.5–6 keV), the modeled ENA maps require a scaling factor of ∼2 to be in agreement with the data. This problem is present in other ENA models with the Maxwellian approximation of multiple ion species and indicates that either a higher neutral density or some acceleration of PUIs in the heliosheath is required.
Implications of Eccentric Observations on Binary Black Hole Formation Channels

Published: November 2021

Orbital eccentricity is one of the most robust discriminators for distinguishing between dynamical and isolated formation scenarios of binary black hole mergers using gravitational-wave observatories such as LIGO and Virgo. Using state-of-the-art cluster models, we show how selection effects impact the detectable distribution of eccentric mergers from clusters. We show that the observation (or lack thereof) of eccentric binary black hole mergers can significantly constrain the fraction of detectable systems that originate from dynamical environments, such as dense star clusters. After roughly 150 observations, observing no eccentric binary signals would indicate that clusters cannot make up the majority of the merging binary black hole population in the local universe (95% credibility). However, if dense star clusters dominate the rate of eccentric mergers and a single system is confirmed to be measurably eccentric in the first and second gravitational-wave transient catalogs, clusters must account for at least 14% of detectable binary black hole mergers. The constraints on the fraction of detectable systems from dense star clusters become significantly tighter as the number of eccentric observations grows and will be constrained to within 0.5 dex once 10 eccentric binary black holes are observed.

Published: November 2021

BACKGROUND: High number of nurses who infected and died from contracting covid-19 put them in a difficult situation during the covid-19. Personal protective equipment is the final line protection for nurses from the risk of Healthcare Associated Infections, while self-efficacy plays an important role in surviving from stressors during the pandemic.
AIM: This review aims to analyze factors related to the use of personal protective equipment and nurse self-efficacy during Covid-19 pandemic.
METHODS: A systematic and comprehensive search using Preferred Reporting Items for Systematic Reviews and Meta-Analyses with six electronic databases were used. Nine cross-sectional, three cohort and survey, one case control, one surveillance study met the inclusion criteria.
RESULTS: From 104 articles screened, 16 articles were included in this review. The high self-protection was the main factor preventing nurses from contracting Covid-19 infection. Lack of personal protective equipment and low cautiousness was the primary factor for nurses of contracting Covid-19. Increased stress, anxiety, depressive symptoms, and insomnia were associated with nurse’s low self-efficacy.
CONCLUSION: The best protection for nurses from Covid-19 exposure is the availability and consistent use of personal protective equipment. Moreover, the consideration for designing staff training programmes and psychological support were recommended for building nurses self-efficacy.

The effect of impurities on the electrical conductivity of aluminum has been studied in detail. The electrical conductivity of aluminum is 65.45% of that of copper. The tensile strength of aluminum wire is 150–170 MPa which, at equal conductivity, is about 65% of the strength of copper wire. This strength of aluminum wire is sufficient for bearing the wire’s own weight but may be too low in case of snow, ice or wind overloads.

One way to improve the strength of aluminum wire is to use aluminum alloys having higher strength combined with sufficiently high electrical conductivity, e.g. the E-AlMgSi alloy (Aldrey). The key strengthening agent of the E-AlMgSi alloy (Aldrey) is the Mg2Si phase which imparts high mechanical strength to aluminum.

In this work we present experimental data on the kinetics of high-temperature oxidation and electrochemical corrosion of indium doped E-AlMgSi aluminum conductor alloy (Aldrey). Thermal gravimetric study has shown that indium doping and high temperature exposure increase the oxidation rate of E-AlMgSi alloy (Aldrey), with the apparent alloy oxidation activation energy decreasing from 120.5 to 91.8 kJ/mole. Alloy oxidation rate data determined using a potentiostatic technique in NaCl electrolyte media have shown that the corrosion resistance of the indium doped alloy is 20–30% superior to that of the initial alloy. With an increase in NaCl electrolyte concentration the electrochemical potentials of the alloys decrease whereas the corrosion rate increases regardless of alloy composition.

In this study, we use the robust optimization techniques to consider a class of multi-objective fractional programming problems in the presence of uncertain data in both of the objective function and the constraint functions. The components of the objective function vector are reported as ratios involving a convex non-negative function and a concave positive function. In addition, on applying a parametric approach, we establish $ \varepsilon $-optimality conditions for robust weakly $ \varepsilon $-efficient solution. Furthermore, we present some theorems to obtain a robust $ \varepsilon $-saddle point for uncertain multi-objective fractional problem.

The main concern of this manuscript is to examine some sufficient conditions under which the fractional order fuzzy delay differential system with the non-instantaneous impulsive condition has a unique solution. We also study the existence of a global solution for the considered system. Fuzzy set theory, Banach fixed point theorem and Non-linear functional analysis are the major tools to demonstrate our results. In last, an example is given to illustrate these analytical results.
