Undressing Architectural Systems
Authors: Guitart Miguel
Published: June 2023

Modernity brought new technical solutions for more efficient space conditioning, improving health and comfort conditions dramatically. As safety and other building codes grew imposingly over the second half of the twentieth century, the incorporation of mechanical systems increased exponentially. However, the growth of mechanical systems in contemporary architectural production often restrains architectural techniques based on local traditionally passive solutions, producing less sustainable, and more expensive spaces. Architects can work on a fully contemporary and sustainable production without the often abusive and blind approach to technology. In this essay, we will propose to reverse part of the design sequence, insisting on a more contextual process based on the relevance of historically valuable passive systems, to finally propose a focus on the design of border conditions as a critical basis for efficiency control, concluding with the consideration of material enclosures as mediating devices for energetic efficiency, and specifically, enclosing mass.

Published: June 2023

Valorization of agricultural wastes is important both economically and environmentally. This study aimed to investigate the use of biochar as a filler to improve the mechanical properties of mortar and to help sequestrate CO2. The biochar was produced by pyrolysis of apricot kernel shell at 500 °C. Nanobiochar particles with dimensions less than 500 nm were obtained by high-energy ball milling process. Scanning electron microscope was used for determining the morphology of nanobiochar. The nanobiochar at different volume percentages [0.00-0.04-0.06-0.08-0.12-0.15%] was added to mortar. The mortar was casted into 40x40x160 mm molds. After water curing at 20°C for 28 days, compressive strength and flexural strength tests were performed. The mixture containing 0.04% nanobiochar by volume had an increase in flexural and compressive strengths by 5% and 15% respectively, while its fracture energies for flexure and compression increased by 98% and 38% respectively compared to the reference mortar. Furthermore, the mixture having 0.12% volume had an increase in flexural and compressive strengths by 32% and 11%, respectively, while the increase in fracture energies for flexure and compression was 52% and 25%, respectively, compared to the reference mortar. The mechanisms of nanobiochar effect on flow, strength, and fracture energy were enlightened. The nanobiochars bridge the cracks, divert the cracks, act as hydration nucleation sites, enhance the matrix by its porous structure, and developed internal curing that led to increase in strength and fracture energy. This study suggests that the biochar produced from the apricot kernel shell has the potential to be used as a carbon sequestering mixture to improve performance of mortar and thereby utilizing waste as a construction material, contributing to the economy and environment.

Bacterial complications in patients with coronavirus infection, new diagnostic and therapeutic possibilities
Authors: Łukaszewski M , Nelke K
Published: June 2023

ABSTRACT
We present the case of a young patient who developed pneumonia during the COVID-19 outbreak. The course of the disease with involvement of interstitial lung tissue atypical for bacterial infections, the picture of infection markers could indicate SARS-CoV-2. The patient was tested by PCR method on admission with negative results.
Due to the atypical follow-up of the disease, suggesting a severe course of SARS, PCR testing of the material collected by BAL was performed BIOFIRE® FILMARRAY® Pneumonia plus Panel (bioMérieux). Legionella pneumophilla and coronavirus genetic materials were found. We conclude that in the described case there was a bacterial co-infection, paved by virus infection. The similar radiological picture of the two cases of pneumonia, as well as the similar infectious response in the blood, specific for atypical infections, may pose a problem in the differential diagnosis. The study was able to confirm the bacterial etiology of pneumonia and introduce targeted treatment. The patient was discharged from the hospital. We believe that in any case of pneumonia of non-bacterial etiology, extending the diagnosis with a PCR pulmonary panel allows early and effective treatment of patients. In the treatment of patients with pulmonary interstitial lesions in the course of virus infections, one should always keep in mind the possibility of atypical co-infections.

Analysis of the Effect of Battery Voltage Drop on Light Intensity on LED and Hologen Type Main Lights in Gentayu UNDIP Electric Cars to Get Good Lighting
Authors: Setiyawan Trio , Kristiawan Timotius Anggit
Published: June 2023

Abstrak - The Gentayu UNDIP electric car requires a lighting system, especially the main lighting system, namely the headlights which must have sufficient light but must be economical in power consumption, because the power used uses a battery that is separate from the main battery for propulsion. So that with a separate battery, the available power is limited, for charging the battery a separate mechanism is made and it can be charged simultaneously with charging the main battery for the Gentayu UNDIP electric car. we will try to do a special analysis of the intensity of light in the lighting system of the main lighting system, to get data on the effect of battery power on light intensity. The test was carried out by observing the decrease in light intensity on two types of lamps, namely LED lamps and halogen lamps. 1x10 Lux every 15 minutes with an average voltage drop of 0.06 volts for every 15 minutes. Meanwhile, for halogen type lamps, the average decrease in light intensity is 6x10 Lux every 15 minutes with a voltage drop of 17 volts, so even though the use of LED type lamps has low power consumption in its use, but a decrease in light intensity when used for a long time cannot be avoided, so it is necessary to make a mechanism for the Gentayu UNDIP electric car so that the battery voltage is maintained when the lighting electrical system is used.

 
A Novel Method for Distinguishing Discontinuities In Ferromagnetic Materials Based On Eddy Current Testing Under Magnetization
Authors: Jia Guangming , Chen Pengchao , Li Rui , Fu Kuan , Wang Rongbiao , Song Kai
Published: June 2023

Detecting inner- and outer-surface discontinuities of drill pipe is of great significance to the evaluation of the quality of the drill pipe. This paper proposes a method based on a magnetized eddy current testing technique to detect inner- and outer-surface discontinuities by analyzing the difference of the imaginary part signal characteristics of the receiving coil. For eddy current testing, the outer-surface discontinuities cause the local conductivity to be zero, while inner-surface discontinuities cause the perturbation of the magnetic permeability on the material surface. In this paper, the effects of conductivity distortion and permeability perturbation on induced eddy currents are analyzed by simulation. The conductivity distortion increases the magnetic field above the discontinuity compared to the magnetic field without the discontinuity, while the permeability perturbation reduces the magnetic field. Next, the difference in coil impedance can be used to distinguish the inner- and outer-surface discontinuities. Finally, the feasibility of the method is verified by experiments, and the results show that the inner- and outer-surface discontinuities can be discriminated.

Authors:   ,   Andrews University, Bardan Christian
Published: June 2023

Carboxypeptidase 0 (CPO) is a protease that cuts acidic amino acids from the carboxy termini of substrate proteins. This study aims to describe the expression patterns of CPO in small mammals. We have sampled tissue from four different species: thirteen-lined ground squirrel, eastern chipmunk, eastern mole, and northern short-tailed shrew. Samples were analyzed via Western blot using two CPO antibodies. Immunoreactive bands likely to be CPO, with molecular weights approximately 42 kDa, were seen predominantly in kidney, liver, and intestinal tissue samples. This suggests CPO could play a specific physiological function in these organs.
Determining the Concentration of Nitric Oxide in Solvent
Authors:   ,   Andrews University, Bankes Emily-Jean
Published: June 2023

The body creates nitric oxide (NO) for signaling. One way that researchers study NO signaling is through the use of model complexes, or molecules that have the same metal ion and a similar molecular shape as biological molecules and are easy to synthesize. Currently researchers have limited ways to deliver precisely-known small quantities of NO to an experiment where they are trying to investigate NO-binding to a transition metal complex. A peak shift in the absorption spectrum at ~530 nm makes it possible for UV-Vis spectroscopy to observe NO binding to cobalt tetraphenylporphyrin (CoTPP). This makes it possible to measure the quantity of NO dissolved in an organic solvent. This project worked to obtain the UV-Vis spectra after varying amounts of NO-saturated solvent was added to CoTPP in a gas-tight cuvette. This spectral data was analyzed using existing computer software and a spectral analysis method developed here. The analysis of spectrophotometric titration data for two solvents yielded preliminary values that let researchers know the concentration of NO in two commonly used solvents: [NO]DCM = 2.29 ± 0.04 mM; [NO]THF = 0.9 ± 0.1 mM.

Published: June 2023

Mustard seed meal (MSM) has been shown to control weeds and pests in crop fields. Prior work showed that a sandy loam soil was superior to a silt loam soil in supporting velvetleaf growth suppression by MSM. To explore this difference, myrosinase enzyme activity was measured in both soils. Results showed no significant difference between the soils. Sand content in Michigan silt loam soil was manipulated in order to test the role of sand content on MSM efficacy in suppressing short-term velvetleaf growth. Results showed that sand enhanced the effect of MSM in suppressing seedling growth and germination.

Authors:   ,   Andrews University, Hwang Irene
Published: June 2023

Investigation of cancer-inducing molecules in cooked foods has led to the discovery of mutagenic heterocyclic amines (HCAs) in meat. The amino acids creatin(in)e and L-phenylalanine form the precursors for these HCAs. Recent research here at Andrews University have found similar mutagenic HCAs produced from plant-based proteins when L-arginine, rather than creatin(in)e, is substituted in high temperature reactions (simulated cooking) with L-phenylalanine. Our research focused on developing HPLC methods to isolate individual candidates that are then screened for mutagenicity via the Ames test. Mass spectroscopy methods were also developed to identfy the molecular structure of these lead mutagenic L-arginine-based HCAs.

While continuing to utilize Shakespeare's language, Munby modernized Othello through the use of contemporary military costumes, props, accents, music, and dance. Munby did not limit his adaptation to solely visual and auditory aspects of Othello, but also took the liberty of contemporizing the principle of "otherness" in the play. This research explores the identification of Munby's character as Iago as "Moral Other," whose actions lead to the fall of his wife, Emilia, a fellow officer, Roderigo, Desdemona, and the protagonist, Othello.

This study examined students' beliefs about the existence of racial discrimination on Andrews' campus and their experience with behaviors classified as microaggressions. We used a survey composed of the following measures: Oxford Happiness Questionnaire (Hill and Argyle, 2002), Intrinsic/Extrinsic Religious Orientation (Francis, Fawcett, Robbins, & Stairs, 2016), Social Dominance (Pratto, Felicia, Sidanius, Stallworth, & Malle, 1994), and Racial and Ethnic Microaggression (Nadal, 2011). Pearson's R correlations and Qualitative Comparative Analysis (Thiem, 2016) were used to analyze subjects' responses (N-147). We found low overall levels of microaggressions across campus and focused our detailed analyses on three specific microaggressions: microinvalidations, 80% of subjects reported at least 1-3 exoticization microaggressions, and Latino/Latina subjects reported a lack of visible representation in media and leadership. These findings provide valuable insight in microaggression research in that not all kinds of microaggressions are experienced in the same way by the same kinds of people.

The main objective of this study was to investigate the relationship between gender role beliefs and intercultural relationship quality for individuals in committed relationships, and between gender role beliefs and willingness to date outside of your respective culture for individuals not in committed relationships. This study also examines romantic relationships using the homophily principle from social psychology, which states that we are more attracted to people who are more similar to ourselves—this may play a role in the prevalence of intercultural romantic relationships. I used Lafontaine’s short version of the Experiences in Close Relationships Scale to measure relationships quality, the short version of the Gender Role Beliefs Scale by Brown & Gladstone, a demographics questions and lastly questions in regards to cultural similarity between couples to characterize the sample. I also measured individual participants’ willingness to cross cultural boundaries when dating. I collected data through the University’s research pool, as well as through researcher’s social media using snowball sampling. The survey was available in both English and in Spanish to increase sample size and accessibility. I ran separate regressions for singles and couples to estimate the relationship between gender role beliefs and close relationships quality. I found there to be no significant correlation between gender role beliefs and couples’ relationship quality (r = -.047, p = .659) or between gender role beliefs and singles’ willingness (r = -.034, p = .711). The correlation between Gender Role Beliefs and Relationship Quality was also not significant (r = -.046, p = .611). I then ran a Welch’s t-test and a Bayesian t-test (using the default Cauchy prior; Wagenmakers et al., 2018) comparing the two split couples group (different versus similar) with Relationship Quality and Gender Role Beliefs as the dependent variable. For relationship quality, almost all of my variables except religion had a Bayes Factor of less than .33 meaning that it would put me in the mild side of moderate evidence in favor of my null hypothesis. By doing Bayesian statistics, and with this project I am contributing to evidence that people shouldn’t be afraid to enter relationships that are different because it doesn’t seem to be the differences that define the quality of the relationship.
"They Called Me Kimchi Breath" and Other Short Narrative Essays: A Study in Composing Asian-American Identity in Short Nonfictional Essays
Authors:   ,   Andrews University, Kim Teddy

The heterogenous lifestyle of Asian-Americans is one of duality. For this ethnic group, personal identity is a mix between American standard practices and inherited Asian traditions. However, even if their cultural practices are primarily American, Asian-Americans are often “Otherized” and outcast when claiming an American identity, forcing them to be regarded as “just Asian.” As such, they are Americans being rejected by America, and as a result have no other place to call home . In this project, I seek to heal the strife this rejection creates, attempting to confront these tensions and resolve them. As a hyphenated American, I am someone who has seen firsthand how my lifestyle is often split into a dichotomy. One arena where this is particularly apparent is food. My culinary choices are a microcosm of my experience, a blend between Korean and American, but primarily seen as “Korean” by others. I accordingly confront the dichotomy of my Asian-American experience by writing food-based essays that reflect on specific events in my childhood.
The Relationship of Emotional Responses to Religious Music and Personality in Religiosity
Authors:   ,   Andrews University, Logan Jasmine
Published: June 2023

Are there relationships between emotional reactions to religious music, personality, and religiosity? Though an integral part of religious services, the role of religious music in religiosity has yet to be broadly explored. The music that we choose to listen to has been shown to elicit emotion and reinforce what is already believed to be true about our own personality and self-identity. If religion is part of this self-identity, then personality could mediate the relationship between emotional reactions and religiosity. Our hypotheses were that the Big Five personality traits would have moderate to strong correlations with emotional reactions, while both emotional reactions and personality traits would have moderate to strong correlations with religiosity. We surveyed 363 Adventist university students from the emerging adult population, and found emotional reactions to religious music to strongly correlate with religiosity (r = .40, p < .001). The results partially supported our hypotheses, in that personality was not found to be a mediator. Rather, they suggest more of a direct relationship between emotional reactions and religiosity.
Evaluation of Anticancer Activity of Heterocyclic Arylidenes on the U87MG cancer cell line
Authors:   ,   Andrews University, Flores Bernadette
Published: June 2023

Glioblastoma multiforme, is a type of brain cancer that develops from glial cells, which surround neurons and provide support and insulation. Previous investigation has shown that some heterocyclic compounds are key in improving the properties of anticancer drugs by enhancing lipophilicity, polarity, and other varying physiochemical features. Synthetic heterocyclic compounds used as anticancer drugs attempt to imitate naturally-occurring ligands and substrates so as to disturb the natural balance in cells. Testing was done to determine the anticancer abilities of hybrid compounds, heterocyclic arylidenes, containing various functional groups, including boronic acids, through a three-day testing process. These compounds were previous synthesized by Jemma McLeish. This was done in order to determine whether the compounds have no effect on glioblastoma viability, increased viability of glioblastoma, or decreased viability of glioblastoma. Results show that only one compound, rhodanine + p-tolualdehyde, was successful, while the other three compounds, rhodanine + o-tolualdehyde, rhodanine + 2-fluoro-4-formylphenylboronic acid, and rhodanine + 3-fluoro-4-formylphenylboronic acid, caused growth acceleration.
Design of a Novel Isoxazoline Class Drug for the Suppressive Treatment of Malaria

Published: June 2023

Design of a novel isoxazoline class drug for the suppressive treatment of erythrocytic malaria through the inhibition of Plasmodium Falciparum Gylceraldehyde-3-phosphate Dehydrogenase (PfGAPDH) gave rise to creation of a synthetic plan for the proposed target molecule α-amino- 3-bromo-4,5-dihydroisoxazol-5-yl propionic acid. A literature-based analysis of the moieties targeting the PfGADPH active site led to the design of the target molecule. Subsequently, an exploration of the literature yielded a possible bifold synthetic plan. Attempts at a model epoxidation reaction using mCPBA and further efforts towards the synthesis of a 3- bromoisoxazoline were shown to be successful using GCMS analysis.

Objectives: The present cross-sectional study was done to acknowledge the level of resilience, its association with quality of life (QoL), community integration, and demographic/injury-related variables, and identify the determinants that affect resilience among spinal cord injury individuals living in the community. Methods: The data were collected from 108 participants using the convenience sampling method. A demographic/injury-related questionnaire was used to identify the characteristics of the participants. The CD-RISC10, World Health Organization quality of life-BREF (WHOQOL-BREF), and community integration questionnaire-revised (CIQ-R) were used to measure resilience, QoL, and community integration. Association between resilience and independent variables was examined through Pearson’s correlation and Point-Biserial correlation, whereas, univariate and multivariate linear regression analyses were applied to identify the influence of the demographic/injury-related factors that contribute to resilience, and independent t-test and ANOVA were employed to identify the determinants that affect resilience. Results: Almost 78% of participants had a moderate-to-high level of resilience. In multivariate analysis, gender, marital status, and profession were found to be statistically significant. Among these predictors, employment had a higher beta value (β=0.684, P=0.026), which signifies its importance in evaluating resilience. Significant associations were established between resilience, QoL domains, community integration, and demographic variables, which included marital status, duration since the injury, and frequency of going out. Discussion: The present research brings attention to the significance of using appropriate interventions, such as vocational rehabilitation support as well as awareness about the injury to help strengthen resilience and reintegration amongst SCI individuals into their communities. A further longitudinal study is recommended to determine predictive factors of the dynamic nature of resilience over time.
