Safe/brave spaces in virtual exchange on sustainability
Authors: Reljanovic Glimäng Malin
Published: July 2022

This article explores the potential for fostering critical intercultural and global awareness through Transnational Virtual Exchange (TVE) focused on sustainability. The study is based on a lingua franca exchange between university students in Argentina, Poland, and Sweden. A qualitative content analysis of student e-portfolios unveiled reflective dimensions construed here as safe/brave spaces, echoing Andreotti’s (2006) notion of soft versus critical global citizenship education. Using theories of critical interculturality and third space, the analysis shows potential for developing participants’ critical reflection through TVE. However, the findings also reveal how in-depth reflection is often a lonely endeavor, overshadowed by project tasks that might unintentionally steer learners toward safe topics and consensus. So far, critical reflection is an underexplored area in empirical Virtual Exchange (VE) research. Student voices in this study bring to the fore questions regarding what it means to approach global citizenship education critically through online collaboration. The findings have implications for future design of VE projects where the focus is on social change through action-oriented tasks, but where critical and dialogic reflection after the completion of a pedagogical task is the salient part.

Published: July 2022

Background

Given the evolution of processing and analysis methods for accelerometry data over the past decade, it is important to understand how newer summary measures of physical activity compare with established measures.

Objective

We aimed to compare objective measures of physical activity to increase the generalizability and translation of findings of studies that use accelerometry-based data.

Methods

High-resolution accelerometry data from the Baltimore Longitudinal Study on Aging were retrospectively analyzed. Data from 655 participants who used a wrist-worn ActiGraph GT9X device continuously for a week were summarized at the minute level as ActiGraph activity count, monitor-independent movement summary, Euclidean norm minus one, mean amplitude deviation, and activity intensity. We calculated these measures using open-source packages in R. Pearson correlations between activity count and each measure were quantified both marginally and conditionally on age, sex, and BMI. Each measures pair was harmonized using nonparametric regression of minute-level data.

Results

Data were from a sample (N=655; male: n=298, 45.5%; female: n=357, 54.5%) with a mean age of 69.8 years (SD 14.2) and mean BMI of 27.3 kg/m2 (SD 5.0). The mean marginal participant-specific correlations between activity count and monitor-independent movement summary, Euclidean norm minus one, mean amplitude deviation, and activity were r=0.988 (SE 0.0002324), r=0.867 (SE 0.001841), r=0.913 (SE 0.00132), and r=0.970 (SE 0.0006868), respectively. After harmonization, mean absolute percentage errors of predicting total activity count from monitor-independent movement summary, Euclidean norm minus one, mean amplitude deviation, and activity intensity were 2.5, 14.3, 11.3, and 6.3, respectively. The accuracies for predicting sedentary minutes for an activity count cut-off of 1853 using monitor-independent movement summary, Euclidean norm minus one, mean amplitude deviation, and activity intensity were 0.981, 0.928, 0.904, and 0.960, respectively. An R software package called SummarizedActigraphy, with a unified interface for computation of the measures from raw accelerometry data, was developed and published.

Conclusions

The findings from this comparison of accelerometry-based measures of physical activity can be used by researchers and facilitate the extension of knowledge from existing literature by demonstrating the high correlation between activity count and monitor-independent movement summary (and other measures) and by providing harmonization mapping.
Supervised Relation Extraction Between Suicide-Related Entities and Drugs: Development and Usability Study of an Annotated PubMed Corpus (Preprint)
Authors: Karapetian Karina , Jeon Soo Min , Kwon Jin-Won , Suh Young-Kyoon
Published: July 2022

BACKGROUND

Drug-induced suicide has been debated as a crucial issue in both clinical and public health research. Published research articles contain valuable data on the drugs associated with suicidal adverse events. An automated process that extracts such information and rapidly detects drugs related to suicide risk is essential but has not been well established. Moreover, few data sets are available for training and validating classification models on drug-induced suicide.

OBJECTIVE

This study aimed to build a corpus of drug-suicide relations containing annotated entities for drugs, suicidal adverse events, and their relations. To confirm the effectiveness of the drug-suicide relation corpus, we evaluated the performance of a relation classification model using the corpus in conjunction with various embeddings.

METHODS

We collected the abstracts and titles of research articles associated with drugs and suicide from PubMed and manually annotated them along with their relations at the sentence level (adverse drug events, treatment, suicide means, or miscellaneous). To reduce the manual annotation effort, we preliminarily selected sentences with a pretrained zero-shot classifier or sentences containing only drug and suicide keywords. We trained a relation classification model using various Bidirectional Encoder Representations from Transformer embeddings with the proposed corpus. We then compared the performances of the model with different Bidirectional Encoder Representations from Transformer–based embeddings and selected the most suitable embedding for our corpus.

RESULTS

Our corpus comprised 11,894 sentences extracted from the titles and abstracts of the PubMed research articles. Each sentence was annotated with drug and suicide entities and the relationship between these 2 entities (adverse drug events, treatment, means, and miscellaneous). All of the tested relation classification models that were fine-tuned on the corpus accurately detected sentences of suicidal adverse events regardless of their pretrained type and data set properties.

CONCLUSIONS

To our knowledge, this is the first and most extensive corpus of drug-suicide relations.
Implications of Accumulated Cold Time for US Kidney Transplantation Offer Acceptance
Authors: Barah Masoud , Kilambi Vikram , Friedewald John J. , Mehrotra Sanjay
Published: July 2022

Background and objectives

Reducing discard is important for the US transplantation system because nearly 20% of the deceased donor kidneys are discarded. One cause for the discards is the avoidance of protracted cold ischemia times. Extended cold ischemia times at transplant are associated with additional risk of graft failure and patient mortality. A preference for local (within the same donor service area) or low–Kidney Donor Risk Index organs, the endogeneity of cold ischemia time during organ allocation, and the use of provisional offers all complicate the analysis of cold ischemia times’ influence on kidney acceptance decision making.

Design, setting, participants, & measurements

Using January 2018 to June 2019 Organ Procurement and Transplantation Network data, we modeled the probability of accepting an offer for a kidney after provisional acceptance. We use logistic regression that includes cold ischemia time, Kidney Donor Risk Index, and other covariates selected from literature. Endogeneity of cold ischemia time was treated by a two-stage instrumental variables approach.

Results

Logistic regression results for 3.33 million provisional acceptances from 12,369 donors and 108,313 candidates quantify trade-offs between cold ischemia time at the time of offer acceptance and donor-recipient characteristics. Overall, each additional 2 hours of cold ischemia time affected acceptance for nonlocal and local recipients (odds ratio, 0.75; 95% confidence interval, 0.73 to 0.77, odds ratio, 0.88; 95% confidence interval, 0.86 to 0.91; P<0.001). For Kidney Donor Risk Index >1.75 (Kidney Donor Profile Index >85) kidneys, an additional 2 hours of cold ischemia time for nonlocal and local recipients was associated with acceptance with odds ratio, 0.58; 95% confidence interval, 0.54 to 0.63 (nonlocal) and odds ratio, 0.65; 95% confidence interval, 0.6 to 0.7 (local); P<0.001. The effect of an additional 2 hours of cold ischemia time on acceptance of kidneys with Kidney Donor Risk Index ≤1.75 (Kidney Donor Profile Index ≤85) was less pronounced for nonlocal offers (odds ratio, 0.82; 95% confidence interval, 0.80 to 0.85; P<0.001) and not significant for local offers.

Conclusions

The acceptability of marginal organs was higher when placements were nearer to the donor and when cold ischemia time was shorter.
Aproximaciones a la retórica de la luz en Octavio Paz
Authors: García Peña Lilia Leticia
Published: July 2022

Las palabras relacionadas con la luz son una constante en la poesía de Octavio Paz. En estas páginas se aborda, a partir de la dimensión retórica de la palabra poética, una aproximación crítica al imaginario de la luz que, a través del léxico, fluye a lo largo de la obra del autor y define, de modo sustancial, sus nociones esenciales del ser, del tiempo y de la poesía misma. La base teórico-metodológica del análisis parte de la perspectiva del método cualificativo que propone Gilbert Durand (2012), el cual toma en cuenta el nivel y la variación léxica no sólo en cuanto a la reiteración cuantitativa, sino a la relevancia simbólica que las palabras cobran en el espacio cultural. La retórica de la luz en la poesía de Octavio Paz confirma la potencia de la palabra poética para crear mundos y conduce a dos grandes sentidos: por una parte, una experiencia del ser de vaciarse de sí para que pueda cumplirse la existencia plena y, por otra, una concepción del tiempo a través de la noción del instante.

Authors: Gempeler Rueda Juanita , Rodríguez Guarín Maritza
Published: July 2022

El curso crónico, y la tendencia a la recaída, así como la escasa utilidad de los medicamentos y los resultados parciales de la psicoterapia en pacientes con Anorexia Nerviosa (AN), sigue siendo un reto para los clínicos. Por otra parte, los conocimientos acerca de la neurobiología y el papel de los rasgos del temperamento en la aparición y mantenimiento de los síntomas en el tiempo, han tenido avances significativos en los últimos años. En este artículo se realizará una revisión narrativa de la literatura acerca de las bases neurobiológicas de la AN, los rasgos característicos del temperamento de los pacientes con AN, y su incorporación en los nuevos enfoques terapéuticos en el tratamiento de los pacientes adultos con AN. Se describen los principales modelos terapéuticos que integran la neurobiología y el temperamento y se discute la evidencia científica de eficacia y efectividad de los mismos. Se concluye que la brecha entre investigación y aplicaciones terapéuticas derivadas de este cuerpo de conocimientos, sigue siendo todavía muy amplia.
La presencia de China en las exportaciones de la manufactura mexicana a Estados Unidos y Canadá
Authors: Morales-López Rodrigo
Published: July 2022

China aumentó su participación en las Cadenas Globales de Valor (CGV) desde 2001, y se le consideró como un “miembro no invitado” en el proceso de integración norteamericano. Elpresente trabajo analiza la presencia de China en las cadenas manufactureras norteamericanas –desde el punto de vista de las exportaciones mexicanas– durante el periodo 2000-2014 mediante el análisis insumo-producto de matrices globales. Los resultados del análisis muestran un descenso en la participación del valor agregado estadounidense incorporado en las exportaciones manufactureras de México hacia Norteamérica, desplazado principalmente por el valor agregado chino consumido finalmente en Estados Unidos. Mientras los insumos provenientes de Estados Unidos y Canadá, presentes en la manufactura mexicana de exportación, muestran señales de reprimarización,los importados desde China manifiestan niveles crecientes de sofisticación.
Suspicious Human Activity Recognition and Alarming System
Authors: S Leela
Published: July 2022

Abstract: Personal safety and social stability are seriously threatened by the violent activities. A variety of methods have been tried to curb the violent activities which includes installing of surveillance systems. It will be of great significance if the surveillance systems can automatically detect violent activities and give warning or alert signals. The whole system can be implemented with a sequence of procedures. Firstly, the system has to identify the presence of human beings in a video frame. Then, the frames which are predicted to contain violent activities has to be extracted. The irrelevant frames are to be dropped at this stage. Finally, the trained model detects violent behaviour and these frames are separately saved as images. The images along with other necessary details such as time and location is sent as an alert to the concerned authority. The proposed method is a deep learning based automatic detection approach that uses Convolutional Neural Network to detect violence present in a video. But, the disadvantage of using just CNN is that, it requires a lot of time for computation and is less accurate. Hence, a pre-trained model, Mobile Net, which provides higher accuracy and acts as a starting point for the building of the entire model. An alert message is given to the concerned authorities using telegram application.
Human Activity Recognition
Authors: Maradani Lohitha
Published: July 2022

Abstract: Human Activity Recognition (HAR) is one of the active research areas in computer vision as well as human computer interaction. However, it remains a very complex task, due to unresolvable challenges such as sensor motion, sensor placement, cluttered background, and inherent variability in the way activities are conducted by different humans. Human activity recognition is an ability to interpret human body gesture or motion via sensors and determine human activity or action. Most of the human daily tasks can be simplified or automated if they can be recognized via HAR system. Typically, HAR system can be either supervised or unsupervised. A supervised HAR system required some prior training with dedicated datasets while unsupervised HAR system is being configured with a set of rules during development. HAR is considered as an important component in various scientific research contexts i.e. surveillance, healthcare and human computer interaction.

Authors: Krishna Himanshu
Published: July 2022

ABSTRACT: Columns are RC building structural elements that are primarily subjected to axial load and moments as they transport them from the superstructure to the substructure. Columns of various shapes and sizes are used. Popular column shapes include square, rectangular, and circular columns, as well as L-shaped, T-shaped, and (+) shaped columns, which are uncommon but provide more interior space than commonly used column shapes. This study aims to examine the seismic performance of multistorey G+10 buildings with Rectangular columns and building with specially shaped columns. According to IS Code 1893(part 1):2016, the proposed buildings are analyzed using equivalent static analysis for zone IV. ETABs are used to analyze the models. After analysis, we conclude that buildings having special columns are safer and have more space as compared to the regular shaped column buildings

Information interventions and health promotion behavior: evidence from China after cadmium rice events
Authors: Zhou Jiehong , Zhang Jing , Zhoui Li
Published: July 2022

Based on the panel data of 777 consumers before and after the information intervention, this paper explores the effectiveness of information intervention methods that enable consumers to adopt health promotion behavior. Using the intervention methods of real testing-information, general news information, and integrated information, a difference-in-difference method is used to conduct an empirical research on the rice consumption behavior of Chinese residents. It is evident from the analysis that the three information interventions do not change the quantity of rice consumed by Chinese residents, consumers only can reduce risks by avoiding purchasing rice from where cadmium rice incidents have occurred frequently. Results of regression analysis indicate that the effect of the integrated information intervention is more effective. Consumers’ responses to information interventions are highly heterogeneous, and the effects of interventions are mainly reflected in consumers with a high degree of risk for eating cadmium rice. The value of this paper is that it not only fills the research gap in the literature on the impact of food testing information on consumer behavior, but also supplements the research on consumer behavior after the food safety crisis related to staple foodstuffs.

Authors: Ding Qin , Huang Shuqi , Sun Zexu , Chen Kaifeng , Li Xin , Pei Qi
Published: July 2022

Aims: Posaconazole is often used for the prophylaxis and treatment of
invasive fungal infections (IFI). However, intra- and inter-individual
differences and drug interactions affect the efficacy and safety of
posaconazole. Precision dosing of posaconazole based on the population
pharmacokinetic (PopPK) model may assist in making significant clinical
decisions. This review aimed to comprehensively summarize the published
PopPK models of posaconazole and analyze covariates that significantly
influence posaconazole exposure. Methods: Articles published until May
2022 for PopPK analysis of posaconazole were searched in PubMed and
EMBASE databases. Demographic characteristics, model characteristics,
and results of PopPK analysis were extracted from the selected articles.
In addition, the steady-state pharmacokinetic profiles of posaconazole
were simulated at different covariate levels and dosing regimens.
Results： Out of the 13 studies included in our review, nine studies
included adults, three included children, and one included both adults
and children. All oral administration models were one-compartment
models, and all intravenous administration models were two-compartment
models. Body weight, proton pump inhibitors, and incidence of diarrhea
were found to be important covariates. In addition, age, sex, total
protein, rifampin, phenytoin, intake of nutritional supplements, levels
of bilirubin and gamma-glutamyl transferase, and administration of
chemotherapy also appeared as covariates in several PopPK models.
Conclusion: Posaconazole exposure was found to be influenced by various
factors such as the type of formulation, the incidence of diarrhea, body
weight, and use of concomitant medications. It was concluded that
routine therapeutic drug monitoring was required for dose adjustment and
in promoting individualized dosing.

Published: July 2022

In order to obtain the dominant immunogen of the protein encoded by
p113/p126 family members of Mycoplasma ovipneumoniae. In this
study, p113/p126 family recombinant proteins were prepared. We evaluated
the antibody level induced by the recombinant protein of each member in
the family and its binding ability with the whole bacterial protein. The
binding ability of recombinant protein to whole bacterial protein was
also evaluated. p113/p126 family members were rich in antigen epitopes.
The recombinant proteins (rP128, rP126, and rP113) have the strongest
binding ability to the serum of infected animals and belonged to the
dominant immunogen. Mice immunized with recombinant protein could
produce specific antibodies. The antibody produced by immunizing mice
with recombinant proteins (rP113, rP109, and rP130) can effectively bind
to bacterial protein. In summary, these results provided a basis for
further research on the development of subunit vaccine and the
establishment of serological diagnosis methods.

Forensic detection – identifying and collecting data for analysis detailed the key contribution forensic science is making in the discharge and or adjudication of criminal justice. The scope of forensic science was reviewed and the associated data collection techniques for analysis were discussed. Existing literature on the subject matter was reviewed and conclusions drawn. Some recommendations for policy and practices were made. Forensic science is often driven by specific issues and scandals (such as a miscarriage of justice), and resources are specifically deployed to address them (3). This means that forensic science is often reactive to “symptoms” that arise (4, 5), rather than engaging in continuous and systematic proactive examination, research, and self-reflection as routine practice. In addition, forensic science frequently works within the framework that “every case is different,” which creates a fundamental tension between research seeking to develop generalizable theories and approaches, and professional practices in crime reconstruction. Therefore, taking a longer term view of the possibilities and potentially desirable directions of the future of forensic science is an important undertaking.

Published: July 2022

Computer and Internet-based crimes are widespread problems that affect a vast number of individuals. Combating such criminals has become a difficult task for competent authorities, as it has enabled a new wave of criminal activity. This phenomenon has drew the attention of security and justice systems all over the world, and these institutions must now deal with the task of reforming and redefining the laws and methodologies used to investigate computer-related criminal activity (Garfinkel, 2010). On the other hand cybercriminals are also making use of existing technologies or systems and new means or techniques to make cybercrime detection, investigation and prevention very difficult. The paper will look at anti-forensics strategies such as data concealment, artefact erasure, trail obfuscation, and attacks on the forensic instruments themselves. Investigators must deal with anti-forensics approaches on a regular basis as digital forensics becomes more significant in current investigations. This article will explore the challenges that investigators and forensic practitioners face when conducting investigations.

Forensic science is important in helping to Analyze and Reconstruct evidence gathered to come to a logical conclusion of an investigation. Crime is not always committed in a straightforward or easily decipherable manner. Nor is it always possible for the investigator to prove what they suspect occurred with the evidence left behind. Analyzing has to do with the piecing of data or evidence together and processed so as to enable the investigator get a fair idea of what one might be looking for. Reconstruction refers to the systematic process of piecing together evidence and information gathered during an investigation to gain a better understanding of what transpired between the victim and the offender during a crime.

Strategies to reduce pesticide residues in food: Remarks on pesticide food poisoning scenarios in Nigeria (1958-2018)
Authors: Omoyajowo Koleayo , Adesuyi Adeola , Omoyajowo Kolawole , Odipe Oluwaseun , Ogunyebi Lanrewaju
Published: July 2022

Food insecurity across the globe, particularly in developing countries such as Nigeria, portends deleterious health challenges owing to various environmental contaminants, including the incursion of pesticides into the biosphere and the consequential retention of pesticide residues in food composition. This study provides a depth of insights into a comprehensive analysis on how the indiscriminate applications of pesticides have distorted both the terrestrial and aquatic ecosystems, altered the food chain and occasioned the appalling incidence of food poisoning. Available data from 1958 to 2018 on pesticide food poisoning scenarios in Nigeria were collected, collated and critically evaluated. The findings of this analytical study, which is navigated through a thorough content and discourse analysis of reliable information, unveiled the various channels through which pesticide residues had penetrated into the food chain and its hazardous implications on the plants, animals and humans being at the receiving ebb of the food chain. In addressing this dilemma, the authors suggested a seam of inter-connected critical and strategic tactical approaches to reduce pesticide poisoning, which, if adopted by the Nigerian government and that of other developing countries, will effectively combat the pervasiveness of this threat to food security.
In vitro sensitivity of Colletotrichum acutatum isolates from strawberry to tebuconazole, prochloraz, fludioxonil and thiophanate-methyl

Published: July 2022

The objective of this study was to determine the Colletotrichum acutatum
isolates sensitivity to several chemical compounds in vitro and to find
their possibilities as a potential control agents for anthracnose disease on
strawberry. C. acutatum J.H. Simmonds, a causing agent of anthracnose, is a
very important pathogen of strawberry, which leads to devastating losses in
its production. The pathogen is effectively controlled by the fungicides.
Thus their application is necessary for achieving high yield and fruit
quality. The sensitivity of 14 isolates of C. acutatum, collected from
commercial strawberry plantations in Serbia, to four fungicides, was
examined by an in vitro sensitivity assay. Based on the results of
morphological, pathogenic and molecular characterization (up to the complex
level), all 14 isolates were determined as C. acutatum. The commercial
formulation of tebuconazole, fludioxonil, prochloraz and thiophanate-methyl
were used for the sensitivity test. The mycelial growth assay method was
used to investigate isolates sensitivity to fungicides. The tested isolates
were very sensitive to prochloraz and fludioxonil, with mean EC50 values of
0.067?0.062 mg L-1 and 0.093?0.043 mg L-1, respectively. Significantly
higher mean EC50 values were observed for tebuconazole (1.473?0.878 mg L-1)
and thiophanate-methyl (1.718?1.592 mg L-1). The toxicity of tested
fungicides in the mycelial growth assay of C. acutatum isolates indicates
the potential implementation of these fungicides in the protection programs
against strawberry anthracnose disease.
Temporal trend of perfluorinated compounds in untreated wastewater and surface water in the middle part of the Danube River belonging to the northern part of Serbia
Authors: Buljovcic Maja , Antic Igor , Kadokami Kiwao , Skrbic Biljana
Published: July 2022

The occurrence and temporal variation of selected priority substances and contaminants of emerging concerns, i.e., eleven perfluorinated compounds (PFCs, belonging to perfluorosulphonates, perfluorocarboxylic acids, and perfluorinated sulphonamides) have been investigated in composite surface water samples of the Danube River at the upstream and downstream locations from the discharge point of wastewater. Among the analyzed compounds, six PFCs (PFOA, PFOS, PFHxA, PFNA, PFDA and PFUnA) were quantified. Overall, the detection frequency for most quantified compounds was very high (>90 %), only PFDA and PFUnA were quantified with less frequency, 33 and 67 %, respectively. The highest quantified concentrations of PFOA and PFOS were 14.9 ng/L (average 12.1 ng/L) and 14.2 ng/L (average 6.11 ng/L), respectively. These ones together with PFHxA (average 10.0 ng/L) were quantified at the highest concentrations in comparison to the other investigated compounds. However, the determined levels of PFOS during investigated sampling period, for all samples analyzed, were always lower than the maximum allowable concentration set for inland river waters but always higher than the environmental quality standard threshold value-AA-EQS of 0.65 ng/L sets by the Directive of European Parliament. Moreover, the levels of PFOA were always several times lower than the set AA-EQS value.
Solution of Abel’s integral equation by Kashuri Fundo transform
Authors: Cuha Fatma , Peker Haldun
Published: July 2022

Integral equations can be defined as equations in which unknown function to
be determined appears under the integral sign. These equations have been
used in many problems occurring in different fields due to the connection
they establish with differential equations. Abel?s integral equation is an
important singular integral equation and Abel found this equation from a
problem of mechanics, namely the tautochrone problem. This equation and some
variants of it found applications in heat transfer between solids and gases
under non-linear boundary conditions, theory of superfluidity, subsolutions
of a non-linear diffusion problem, propagation of shock-waves in gas field
tubes, microscopy, seismology, radio astronomy, satellite photometry of
airglows, electron emission, atomic scattering, radar ranging, optical fiber
evaluation, X-ray radiography, flame and plasma diagnostics. Integral
transforms are widely used mathematical techniques for solving advanced
problems of applied sciences. One of these transforms is the Kashuri Fundo
transform. This transform was derived by Kashuri and Fundo to facilitate
the solution processes of ODE and PDE. In some works, it has been seen that
it provides great convenience in finding the unknown function in integral
equations. In this work, our aim is to solve Abel?s integral equation by
Kashuri Fundo transform and some applications are made to explain the
solution procedure of Abel?s integral equation by Kashuri Fundo transform.

In this paper, we study rotational hypersurfaces in 4-D Lorentz-Minkowski
space with density. We give the weighted mean curvature of a rotational
hypersurface about spacelike (timelike) axis in E41 with densities
ex2-y2-z2 and ex-y-z (e-y2-z2-t2 and e-y-z-t). We obtain the parametric
expressions of the rotational hypersurfaces about spacelike (timelike) axis
in E4 1 with density ex2-y2-z2 (e-y2-z2-t2) with respect to the weighted
mean curvature and give some examples for them. Also, we give some results
about rotational hypersurfaces about spacelike (timelike) axis in E41 with
density ex-y-z (e-y-z-t) to be with constant or non-constant weighted mean
curvature.

exergy analyzes were carried out by using the engineering equation solver
program to thermodynamic analysis of seven different refrigerants in the
system designed by determining the mass-flow rate to obtain 10 kW heating
power, which was selected by using the coolselector two program by using the
refrigerant temperature values and operating pressure values. The condenser
dew point temperature was kept at +30?C and the evaporator dew point
temperature was kept at -1?C. Calculations were made under atmospheric
conditions by keeping subcooling at -2?C, superheating at +5?C, and
ambient temperature at 20?C. The coefficients determining the system
performance were obtained for the highest R22 refrigerant and the lowest for
R513A refrigerant. The exergy heating efficiency was obtained in the highest
R22 and lowest R407C refrigerants, respectively. The calculated exergy
cooling efficiencies were observed to be the highest R407C and the lowest
R513A, respectively. The results of the study are presented in graphics. It
has been revealed that the most suitable fluid in the designed industrial
cabinet system is the system using R22.

OBJECTIVE: To determine whether the use of dipeptidyl peptidase 4 (DPP-4) inhibitors and glucagon-like peptide-1 receptor agonists (GLP-1 RAs), separately, is associated with an increased risk of acute liver injury compared with the use of sodium-glucose co-transporter-2 (SGLT-2) inhibitors.

RESEARCH DESIGN AND METHODS: We used the United Kingdom Clinical Practice Research Datalink linked with the Hospital Episode Statistics Admitted Patient Care and the Office for National Statistics databases to assemble two new-user, active comparator cohorts. The first included 106,310 initiators of DPP-4 inhibitors and 27,277 initiators of SGLT-2 inhibitors, while the second included 9470 initiators of GLP-1 RAs and 26,936 initiators of SGLT-2 inhibitors. Cox proportional hazards models with propensity score fine stratification weighting were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of acute liver injury.

RESULTS: Compared with SGLT-2 inhibitors, DPP-4 inhibitors were associated with a 53% increased risk of acute liver injury (HR: 1.53, 95% CI: 1.02-2.30). In contrast, GLP-1 RAs were not associated with an overall increased risk of acute liver injury (HR: 1.11, 95% CI: 0.57-2.16). However, an increased risk was observed among female users of both DPP-4 inhibitors (HR: 3.22, 95% CI: 1.67-6.21) and GLP-1 RAs (HR: 3.23, 95% CI: 1.44-7.25).

CONCLUSIONS: In this population-based study, DPP-4 inhibitors were associated with an increased risk of acute liver injury compared with SGLT-2 inhibitors in patients with type 2 diabetes. In contrast, an increased risk of acute liver injury was observed only among female GLP-1 RA users.

Selama ini pemanfaatan tanaman turi oleh  masyarakat masih terbatas, bagian dari tanaman turi yang banyak dimanfaatkan oleh masyarakat hanya bunganya.  Padahal biji turi yang berbentuk bulat berwarna kuning kecoklatan mempunyai rasa dan aroma khas jenis kacang-kacangan juga dapat dimanfaatkan karena kaya dengan mineral dan vitamin serta mengandung protein. Biji dari tanaman turi dapat digunakan sebagai bahan baku alternatif  dalam pembuatan  kecap karena biji tanaman turi tersebut  mempunyai komposisi  kandungan gizi yang tidak jauh berbeda dengan kedelai, terutama kandungan  protein biji turi sebesar 36,21%  yang setara  dengan kandungan protein kedelai sebesar 37,5% Pembuatan kecap dengan menggunakan ekstrak pepaya dan nanas dapat mempercepat waktu pembuatan kecap secara hidrolisis protein karena adanya enzim papain pada pepaya dan enzim bromelin pada nanas. Tujuan dari penelitian ini adalah untuk mengetahui kadar protein kecap biji turi dengan menggunakan ekstrak pepaya dan nanas serta untuk  mengetahui organoleptik kecap biji turi dengan menggunakan ekstrak pepaya dan nanas. Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) pola faktorial. Faktor tersebut yaitu jenis ekstrak yang digunakan (ekstrak pepaya dan ekstrak nanas) dan penambahan volume ekstrak (80 ml, 100 ml, dan 120 ml) dengan 6 kombinasi perlakuan. Hasil penelitian menunjukkan bahwa penambahan ekstrak pepaya dan nanas berpengaruh pada kadar protein kecap. Hasil kadar protein tertinggi pada perlakuan J1V1 yaitu 12,11%,  sedangkan  kadar protein terendah pada perlakuan J2V1 yaitu 7,53 %. Kecap dengan perlakuan menggunakan ekstrak nanas, volume 120 ml merupakan kecap yang dapat diterima oleh masyarakat.
