ABSTRACTBackground: Nutrition and diets are critical factors for T2DM patients to maintain health. Nutrition education are considered less effective because most patients have not implemented them. This research tries to develop program innovation by combining nutrition counseling and cooking assistance for T2DM outpatients. This study aimed to know the risk factors for T2DM  and determine the effectiveness of programmed nutrition education (NEP) on changes in nutrient intake in patients with T2DM. Methods: A total of 70 participants registered as T2DM outpatients at Kedung Kandang primary healthcare center in Malang city. Subjects were recruited using a 'quota sampling' technique. The design of this study is a quasi-experiment study using a comparison of the control (n=32)-treatment group (n=38). This research was conducted from September to November 2018. Fifty minutes of intensive individual counseling and cooking assistance were provided to T2DM patients and families. The data were analyzed using independent sample t-test, Wilcoxon Mann Whitney U-test, and logistic regression. The patients’ 4-d dietary records of 3 normal days and 1 holiday/weekend were assessed after 24 hours.Results: From this study it can be seen that intake of amino acid lysine was significantly higher in the  treatment group than the control group (p = 0.04). The intake of fiber, MUFA, and PUFA was greater in the intervention group, while sodium intake was lower in the intervention group. The risk factors of T2DM incidence were age (p = 0.036), education (p = 0.043), waist circumference (p = 0.015), and carbohydrate intake (p = 0.033). Conclusion: T2DM patients treated with individual nutrition counseling and cooking assistance gained a higher intake of fiber, amino acid lysine, and unsaturated fatty acids. The most influential risk factors of T2DM incidence are age, education, waist circumference, and carbohydrate intake. Keywords: nutrition counseling, cooking assistance, nutritional intake, T2DM.

Transfers and Resilience in Economic Networks
Authors: Montecinos-Pearce Alejandro , Parro Francisco
Published: June 2023

We study how decentralized transfers, originated by a selfish motive to preserve direct links, affect the resilience of a network against a shock. Well-off agents transfer resources to other agents in order to prevent the shock from reaching their neighbors. We show that the connectivity of a well-defined portion of the network, specifically, the propagation network, determines the resilience of the entire network. We also show how, although transfers are allocated to a subset of agents, the resilience effect of these transfers is amplified. Lastly, we show that the wealth distribution impacts resilience by determining the incentives of the agents to transfers resources.

Published: June 2023

Rehabilitation, upgrading, or strengthening of structural members, especially columns, has become the target of many researchers because columns are the most important members in a building and the failure of columns causes direct collapse in the building. This study aims to get an assessment of the best pattern of steel-framed jacket used for strengthening axially loaded concrete columns by numerically studying the behavior of the column for different cases of the same amount of steel jacket. The jacket consists of four angles and/or battens, lacings, or battens with lacings. The nonlinear analysis program designated as ARCC-SSJ (Analysis of Reinforced Concrete Columns Strengthened by Steel Jacket) is used to compare different patterns with the same and different cross-sections of battens and single lacing, as well as battens and lacing with battens taken into account. It is found that lacing with battens is the best pattern for the same amount of steel jacket with different cross-sectional areas. It is observed that the load-carrying capacity of the column increased by approximately 1.8 and 1.15% over that of battens alone in the case of a lacing angle of

Rehabilitation of overload-damaged reinforced concrete columns using ultra-high-performance fiber-reinforced concrete
Authors: Alasmari H. A.
Published: June 2023

One of the problems experienced by reinforced concrete (RC) structures, whether a mistake at the design phase or a change in building use, is an overload. The goal of this study is to determine whether ultra-high-performance fiber-reinforced concrete (UHPFRC) is effective in repairing damaged concrete columns utilizing 30 mm thin concrete jacketing made of different steel fibers at various contents with varied aspect ratios (28, 37, and 45). Nine pieces of 500 mm long RC column specimens with a cross-sectional size of 150 mm × 150 mm were cast as part of the experimental program. By loading these columns with roughly 90% of their actual ultimate axial load capacities, damage was caused, and the columns were subsequently strengthened and rebuilt using UHPFRC jacketing materials. The results demonstrated that when steel fiber content increased, so did the mechanical qualities, such as compressive and tensile strengths. Rehab materials that contained 0.5% steel fiber recovered 138% of their maximum load-bearing capacities, while materials that contained 1.5% steel fiber recovered 164% of their original capacities, which were roughly 1.38–1.64 times that of the unjacketed reference column. Additionally, it was observed that employing steel fiber in UHPFRC contents in these approaches resulted in the ultimate displacement being improved from 2.91 to 5.53 mm at 1.5% of steel fiber content, which is an increase of almost double that of control specimens.
A stacked dielectric magnetoelectric dipole antenna with embedded ceramics
Authors: Luo Wei , Wang Zihao , Ren Yi , Ran Jia , Wang Bing
Published: June 2023

A stacked dielectric magnetoelectric antenna with embedded ceramics (SDMEA-EC) is proposed. The antenna consists of a stacked dielectric resonator antenna with embedded ceramics and a leaf-shaped electric dipole (LSE-Dipole). To improve the performance of the magnetoelectric dipole antenna, a novel verification method is proposed by analyzing equivalent magnetic currents to meet the Huygens element principle. The stacked structure with embedded ceramics is helpful for expanding the impedance bandwidth. The electric dipole not only participates in the radiation but also is a part of the feed network, which simplifies the overall structure. The prototype of the proposed stacked dielectric resonator magnetoelectric antenna achieves an impedance bandwidth of 20.2 % in the high frequency band (5.35 GHz–6.55 GHz) and 13.4 % in the low frequency band (4.54 GHz–5.19 GHz), an over 6.7 dBi gain, and a cross-polarization discrimination (XPD) of greater than 30 dB.

Authors: Kumar Ashok S. , Yadav Jitendra , Kurre Santosh K.
Published: June 2023

In the search for environmentally acceptable alternative fuels for diesel engines, biodiesel is a tempting option. Still, the long-term repercussions are excessive noise and vibration, as well as irregular and unpredictable combustion, which leads to knocking. In this study, an attempt was made to study the vibrational behavior of diesel engines fuelled with neat diesel and jatropha biodiesel blends (BJ0, BJ10, BJ20, BJ30, and BJ40) and lubrication oil degradation at different operating time periods (40, 60, 80 and 100 h). Vibration analysis is done through the measurement of horizontal and vertical frequencies and physical characteristics of lubrication are done through the determination of viscosity and density. Observation shows that there is a definite relationship between the degradation of oil and the vibration signatures of the engine. It is observed that BJ20 is the best-suited fuel for optimized performance. The highest frequency of vibration is reported in the frequency range of 1039–1041 Hz. The present study provides the guidelines for condition monitoring of bio fuelled engines for proper maintenance and scheduling change of oil.

Authors: Ammari Nada , Gantare Abdellah
Published: June 2023

Objectives

To examine graduate students’ perceptions of their nursing professional identity within the university-based educational system.

Methods

A qualitative phenomenological approach was adopted involving the completion of in-depth interviews and focus groups among master’s degree students in Morocco.

Results

The shift to university-based nursing education system was associated with the development of a positive self-image, sense of empowerment, and attachment to professional values in addition to role extension and involvement in research.

Conclusions

The perceived external barriers such as negative social image, role ambiguity, and unsupportive work environments, limit the reach of the positive influence of the educational shift and may lead to doubts in integrating the clinical workspace.
Are these Nothing but Sorcerers? – A linguistic analysis of Q Ṭā-Hā 20:63 using intra-Qurʾānic parallels
Authors: van Putten Marijn
Published: June 2023

The seemingly ungrammatical wording of Q Ṭā-Hā 20:63 ʾinna hādhāni la-sāḥirāni has been cause for much debate, both in traditional Muslim sources as well as in modern discussion. This paper sets out to reevaluate the grammar of the various reading that are present by comparing them not against the normative grammar as it is established by the medieval grammarians, but rather by comparing its grammar to other, comparable construction in the Qurʾān. By analyzing this Qurʾānic verse within its intra-Qurʾānic parallels it is argued that the minority reading ʾin hadhāni la-sāḥirāni is the original intended reading of the ʿUthmānic text, while the grammatically problematic majority reading ʾinna hādhāni la-sāḥirāni is to be understood as an approximation to popular non-ʿUthmānic readings. Through the comparison with other verses, it is also shown that we may gain deeper understanding into verses of constructions of the type found in Q al-Ṭāriq 86:4 (wa-ʾin kullu nafsin la-mā ʿalayhā ḥāfiẓun) and shed light on some of the competing canonical readings in these verses.
Diversity in geology and geophysics degree programs in Historically Black Colleges and Universities (HBCUs)
Authors: Aluka Innocent J.
Published: June 2023

The underrepresentation of people from culturally and linguistically diverse (CLD) backgrounds in geology, geophysics, and other STEM programs (Science, Technology, Engineering and Mathematics) is well documented in the United States. Only two universities out of about 107 HBCUs have geology and geophysics degree programs, even though there are over 400 universities in the United States that offer geology and geophysics degree programs. The low presence of these degree programs in HBCUs is a major barrier that has visible consequences. For example, Blacks and other CLD individuals are forced to be intellectually unchallenged, suppressed, and underutilized. Other consequences include low opportunities in college admission, employment, promotion, and life success. How can this problem be solved? This article addresses this question.

NLRP3 inflammasome activation underlies the neuro-oxidative stress associated with Methamphetamine (METH) and SARS-CoV2 induced co-morbidity in human microglia
Authors: Machhar Janvhi Suresh , Abou-Jaoude Elias , Schwartz Stanley A. , Aalinkeel Ravikumar , Mahajan Supriya D.
Published: June 2023

Acute and chronic use of Methamphetamine (METH) has critical immunological implications and METH users are more vulnerable to SARS-CoV2 infection. Inflammasomes are activated in response to SARS-CoV2 infection. METH also activates NLRP3 inflammasome in microglia and promotes neuro cognitive deficits. The goal of the study was to examine the involvement of NLRP3 inflammasome in METH and/or SARS-CoV2 induced neuro-oxidative stress in microglial cells. Our results suggests that METH +/− SARS-CoV2 initiated a neuro immune-inflammatory response and mitochondrial oxidative stress via NLRP3 inflammasome activation induced increased Caspase −1 and increased lipid peroxidation. Our data suggests that SARS-CoV2 infection in METH abusing subjects may result in long-term neurological deficits resulting from microglial dysfunction and apoptosis attributed to NLRP3 inflammasome activation.
Separation of 71,72As from alpha-particle induced reaction on gallium oxide target using naturally occurring alkaloid caffeine
Authors: Mitra Sayantani , Naskar Nabanita , Samanta Puja , Banerjee Pujarini , Lahiri Susanta , Ghosh Kalpita , Chaudhuri Punarbasu
Published: June 2023

Gallium oxide target was irradiated with 46 MeV alpha-particle beam, which produced 71,72As and 67Ga radioisotopes in the matrix. Separation of radio-arsenics from the bulk gallium target was carried out by caffeine, a nature-resourced reagent, extracted from black tea leaves. 71,72As radionuclides were preferentially attached with caffeine and precipitated with caffeine in 2 M Na2SO4 solution as caffeine was insoluble in aqueous medium under this condition. With increase in weight of caffeine, extraction of 71,72As and bulk gallium significantly increased. Bulk Ga along with 67Ga remained in the supernatant. Geometry optimization of caffeine–metal complex was carried out by theoretical computational analysis. DFT calculation corroborated with the experimental findings where As3+ preferentially binds with caffeine in presence of gallium and arsenic. As evidenced by the short As–O and As–N distances, the high binding energies are a result of the metal ion’s strong binding to the carbonyl and nitrogen centres, whereas no such result could be obtained in case of bulk gallium.
Research progress on properties of cement-based composites incorporating graphene oxide
Authors: Zhang Peng , Sun Yaowen , Wei Jiandong , Zhang Tianhang
Published: June 2023

Graphene oxide (GO) is a two-dimensional derivative of graphene material, with carboxy, hydroxy group functional groups at the middle of the sheets, and oxygen-containing functional groups at sheet edges. It has multiple advantages, such as high strength, hydrophilicity, and strong reactivity. With the development of construction materials, GO has been widely used as a nano-reinforced material in cement-based composites (CBCs). Based on a large amount of relevant literature, the preparation and dispersion behavior of GO-reinforced CBC are summarized. Besides, the impact of GO on the workability, volume stability, mechanical performance, and durability of CBC are discussed. Moreover, the influencing mechanism of GO on the hydration of CBC is expounded. From the findings of this review, the following conclusions can be drawn: the fluidity of CBC will be decreased when GO is evenly dispersed in the cement slurry, which results in a loss of workability of CBC. Meanwhile, the addition of GO improves the volume stability of CBC, while the tensile, compressive, and flexural strengths are all improved to varying degrees. The improvement of GO on the durability of CBC is mainly reflected in the corrosion resistance and permeability resistance. In addition, problems existing in the current research are summarized and future perspectives are put forward. The review work in this article could offer important guidance for further research and implementation of GO-doped CBC in practical engineering.
What Drives Business Cycles in Egypt? An Analysis of Coincident and Leading Indicators
Authors: Hegazi Nourhan , Noureldin Diaa , Zaki Chahir R.
Published: June 2023

The paper proposes a chronology for the Egyptian economy by detecting phases of expansions and recessions during the period (2002–2019). It examines the cyclical behavior of variables that are considered potentially useful in measuring or predicting aggregate economic activity. To do so, we combine the National Bureau of Economic Research (NBER) approach together with time series analysis techniques to select the variables best suitable to play the role of coincident and leading indicators. This methodology is found to be the most appropriate when there is no well-established reference chronology as a benchmark for the cyclical analysis, which is the case of Egypt. As a result, two composite indexes are constructed: 1) the composite index of coincident economic indicators (CEI), which can be considered an adequate measure for the Egyptian business cycle; 2) the composite index of leading economic indicators (LEI) that shows good performance in anticipating aggregate economic activity in Egypt. Moreover, the empirical results indicate that total employment, consumption, and investment move coincidently with the reference cycle, while exchange rate and interest rate variables lead the reference cycle and have strong predictive power for economic activity in Egypt.

A systematic chemical study of the secondary metabolites of the marine fungus, Penicillium chrysogenum (No. Y20-2), led to the isolation of 21 compounds, one of which is new (compound 3). The structures of the 21 compounds were determined by conducting extensive analysis of the spectroscopic data. The pro-angiogenic activity of each compound was evaluated using a zebrafish model. The results showed that compounds 7, 9, 16, and 17 had strong and dose-dependent pro-angiogenic effects, with compound 16 demonstrating the strongest pro-angiogenic activity, compounds 6, 12, 14, and 18 showing moderate activity, and compounds 8, 13, and 19 exhibiting relatively weak activity.

Effects of the impregnation materials borax, boric acid, and Tanalith-E on combustion properties of Oriental beech (Fagus orientalis Lipsky) were investigated. The immersion method was used for long-term impregnation (24 h). After the impregnation process, polyurethane as well as synthetic, acid hardening, and water-based varnishes were applied on the wood sample surfaces according to company’s suggests. The combustion test was performed according to the ASTM-E 69 standard. The mass reduction, release of gasses (CO, NO, O2), and the temperature differences of samples were determined for each 30 seconds during combustion. It was shown that the most mass reduction occurred when both polyurethane varnish and boric acid were applied.
Characterization of fly ash from the gasification of wood and assessment for its application as a soil amendment
Authors: Pana Hui , Eberhard Thomas L.
Published: June 2023

Fly ash was collected as a byproduct from the processing of southern pine wood chips in a pilot-scale biomass gasifier. General properties of the fly ash were determined to assess its applicability as a soil amendment. Its alkaline pH (9.5) and high concentrations of Ca, K, and Mg suggest that it could be used as both a liming agent and a fertilizer. The concentrations of most heavy metals in all ash samples in this study were lower than the ecological soil screening levels used as a guideline. A sequential extraction analysis was used to evaluate the bioavailability of selected nutrient elements and pollutant heavy metals in the fly ash. Most nutrient elements were present in exchangeable/acid extractable and easily reducible fractions. The heavy metals were generally less bioavailable, thus ameliorating concerns for land application of fly ash, with or without prior combustion. Comparison of sequential extraction test results for all of the ashes indicated that the conditions experienced during gasification, such as high processing temperatures, impacted both the total heavy metal concentrations and their potential bioavailabilities.
Revealing dynamic-mechanical properties of precipitates in a nanostructured thin film using micromechanical spectroscopy

Published: June 2023

Nanostructured materials with their remarkable properties are key enablers in many modern applications. For example, industrial dry-milling processes would not be as widely spread without the use of hard, wear-resistant metal nitride coatings to protect the cutting tools. However, improving these nanostructured thin films with regard to dynamical properties is demanding as probing respective parameters of (sub-)micron layers without any substrate influence is still challenging. To extend the scientific toolbox for such spatially confined systems, a novel methodological approach based on resonance peak measurements of a cantilever-transducer system termed micromechanical spectroscopy (µMS) is developed and applied to a Al0.8Cr0.2N model system. The mainly wurtzite type supersaturated Al0.8Cr0.2N system showed precipitation of cubic CrN at grain boundaries and local Cr variations upon annealing at 1050°C. This was accompanied by an increase in the previously unknown damping capability of 63 percent and an increase in Young’s modulus by 36 percent.

Impact statement

There is a wide variety of applications for nano- to micrometer-sized thin films in today’s engineering technology, from thermal barrier- and wear-resistant coatings in turbines and bearings, over diffusion barriers and heatsinks in microelectronic devices, to optically active layers in lasers or mirrors. The mechanical properties of such thin films are oftentimes governed by their thermal history, leading to either intentional or undesired changes in the microstructure (e.g., the formation of precipitates). While the investigation of such features is usually constricted to static analysis using high-resolution techniques, such as transmission electron microscopy, understanding their impact on dynamic properties of the film remains a challenge. However, these are highly relevant in many engineering applications where cyclic behavior is common, such as high-speed dry milling. In the present work, we investigate the change in mechanical damping capability upon annealing of a 6-µm thin AlCrN film, commonly used in demanding dry-milling applications, using micromechanical spectroscopy (µMS) of cantilever-shaped specimens. After a carefully adjusted heat treatment, the film exhibits the formation of cubic CrN precipitates in an otherwise wurtzite AlCrN matrix, which leads to a previously unknown beneficial increase in damping capability of the film.

Published: June 2023

The stance of U.S. monetary policy has tightened significantly starting in March 2022. At the same time, the share of firms in financial distress has reached a level that is higher than during most previous tightening episodes since the 1970s.
Firm Financial Conditions and the Transmission of Monetary Policy
Authors: Ferreira Thiago R. T. , Ostry Daniel A. , Rogers John
Published: June 2023

We study how the transmission of monetary policy to firms' investment and credit spreads depends on their financial conditions, finding a major role for their excess bond premia (EBPs), the component of credit spreads in excess of default risk. While monetary policy easing shocks compress credit spreads more for firms with higher ex-ante EBPs, it is lower-EBP firms that invest more. We rationalize these findings using a model with financial frictions in which lower-EBP firms have flatter marginal product of capital curves. We also show empirically that the cross-sectional distribution of firm EBPs determines the aggregate effectiveness of monetary policy.
Inflation and Real Activity over the Business Cycle
Authors: Bianchi Francesco , Nicolò Giovanni , Song Dongho
Published: June 2023

We study the relation between inflation and real activity over the business cycle. We employ a Trend-Cycle VAR model to control for low-frequency movements in inflation, unemployment, and growth that are pervasive in the post-WWII period. We show that cyclical fluctuations of inflation are related to cyclical movements in real activity and unemployment, in line with what is implied by the New Keynesian framework. We then discuss the reasons for which our results relying on a Trend-Cycle VAR differ from the findings of previous studies based on VAR analysis. We explain empirically and theoretically how to reconcile these differences.
The FOMC’s Use of Operational Targets: 85 Years and Counting
Authors: Huther Jeffrey , Klee Elizabeth , Kiernan Kevin , Rodriguez-Shah Ethan
Published: June 2023

This paper uses summaries of the Federal Open Market Committee’s (FOMC’s) meetings to identify its operational targets and map those to operating regimes. We find that operational targets were more often discussed in the earlier part of the FOMC’s 85-year history, but recent years have seen a resurgence in discussions. We identify distinct operating regimes and findthat regimes with discussions of multiple targets, usually rate and quantity pairs, are more common than regimes dominated by discussions of single targets. We document that the current period (the 2007-2009 financial crisis to today) is a notable break in operational targets fromearlier periods. We also show that shifts in operational targets occur during recoveries, or after a significant downturn in the macroeconomy.

Authors: DURSUN Asiye , CEYHAN Aydoğan Aykut
Published: June 2023

The aim of this study is to examine the effectiveness of 10 session psycho educational program which was developed within the scope of the research to decrease the problematic internet usage level of adolescents. Embedded design, which is one of the mixed method types of research, was used in the research. In the quantitative experimental stage of the research, experiment, control, and placebo x pretest-posttest-follow-up test design was used. In addition, qualitative data were obtained with the focus group interview after the experiment. The study was started with 12 adolescents in each group, but it was completed with 11 adolescents in the experimental and control group, 12 in the placebo group, due to the loss of test subjects during the experiment. The data of the research was collected via Problematic Internet Usage Scale-Adolescent Form, Basic Needs Scale and Personal Information Questionnaire. The quantitative findings obtained from the research indicated that as a result of the experimental process the program has a significant effect on decreasing problematic internet usage levels of adolescents and meeting the need for love and belonging; however, it does not have a significant effect on the level of meeting other psychological needs. There was no significant difference between the control and placebo groups. Moreover, the findings of the focus group interview conducted with the experimental group revealed that adolescents gained awareness of internet use, their frequency of internet use decreased, and their aims changed, and they tried to meet their psychological needs in a social environment.
SKIL/SnoN attenuates TGF-β1/SMAD signaling-dependent collagen synthesis in hepatic fibrosis
Authors: Chi Cheng , Liang Xifeng , Cui Tianyu , Gao Xiao , Liu Ruixia , Yin Chenghong
Published: June 2023

The Ski-related novel gene (SnoN), encoded by the SKIL gene, has been shown to negatively regulated transforming growth factor-β1 (TGF-β1) signaling pathway. However, the roles of SnoN in hepatic stellate cell (HSC) activation and hepatic fibrosis (HF) are still unclear. To evaluate the role of SnoN in HF, we combined bulk RNA sequencing analysis and single-cell RNA sequencing analysis to analyse patients with HF. The role of SKIL/SnoN was verified using liver samples from rat model transfected HSC-T6 and LX-2 cell lines. Immunohistochemistry, immunofluorescence, PCR, and western blotting techniques were used to demonstrate the expression of SnoN and its regulatory effects on TGF-β1 signaling in fibrotic liver tissues and cells. Furthermore, we constructed competitive endogenous RNA regulatory network and potential drug network associated with the SnoN gene. We identified SKIL gene as a differentially expressed gene in hepatic fibrosis. SnoN protein was found to be widely expressed in the cytoplasm of normal hepatic tissues, whereas it was almost absent in HF tissues. In the rat group subjected to bile duct ligation (BDL), SnoN protein expression decreased, while TGF-β1, collagen III, tissue inhibitor of metalloproteinase 1 (TIMP-1), and fibronectin levels increased. We observed the interaction of SnoN with p-SMAD2 and p-SMAD3 in the cytoplasm. Following SnoN overexpression, apoptosis of HSCs was promoted, and the expression of HF-associated proteins, including collagen I, collagen III, and TIMP-1, was reduced. Conversely, downregulation of SnoN inhibited HSC apoptosis, increased collagen III and TIMP-1 levels, and decreased matrix metalloproteinase 13 (MMP-13) expression. In conclusion, SnoN expression is downregulated in fibrotic livers, and could attenuate TGF-β1/SMADs signaling-dependent de-repression of collagen synthesis.

Authors: Meng Zhaosheng , Ma Chen , Xie Yunyue
Published: June 2023

Chock-shield support is usually used in undergroud coal mining to protect the roof. However, as the mining depth gets deeper, impact load that came from the roof becomes stronger and more frequent. This causes the support to bear a large number of dynamic loads, and reducing its reliability. To improve the support performance of the chock-shield support, the mixed-kinetic model was established using the mechanical-hydraulic co-simulation method. The load distribution law of the support joint under impact load form different stability forces, impact load amplitude, and impact frequency is discussed. The mechanical-hydraulic cooperative response of the chock-shield support are obtained. The results show that different joints show typical non-uniformity characteristic during the loading process. The proposed mechanical-hydraulic co-simulation method can more accurately obtain the dangerous points of hydraulic support reliability. The results of this study will help to improve the reliability of the chock-shield support.
