Effects of beam deviation on the mode purity of a vortex beam
Authors: Luo Chuankai
Published: May 2022

The vortex beam has extensively demonstrated impressive significance in many applications. As a key parameter, the mode purity (MP) of a vortex beam is easily influenced by beam deviation. In this paper, the deviation models of the vortex beam — a beam wander model (BWM) and a phase singularity wander model (PSWM) are proposed. The MP expressions of these models are derived, and the influence of beam parameters on MP are studied through numerical methods. It is found that MP remains constant with the variation of azimuth of phase singularity, the maximally relative radial distance varies with the topological charge inversely and the influence of PSWM on MP is greater than BWM. Furthermore, the MP of a radially symmetrical vortex beam array is equal to that of each beamlet, and will increase with the decline of relative radial distance of each beamlet. The results can provide theoretical basis for further researches on orbital angular momentum (OAM) communication and vortex beam synthesis.

Published: May 2022

Heterogeneity of cancer means many tumorigenic genes are only aberrantly expressed in a subset of patients and thus follow a bimodal distribution, having two modes of expression within a single population. Traditional statistical techniques that compare sample means between cancer patients and healthy controls fail to detect bimodally expressed genes. We utilize a mixture modeling approach to identify bimodal microRNA (miRNA) across cancers, find consistent sources of heterogeneity, and identify potential oncogenic miRNA that may be used to guide personalized therapies. Pathway analysis was conducted using target genes of the bimodal miRNA to identify potential functional implications in cancer. In vivo overexpression experiments were conducted to elucidate the clinical importance of bimodal miRNA in chemotherapy treatments. In nine types of cancer, tumors consistently displayed greater bimodality than normal tissue. Specifically, in liver and lung cancers, high expression of miR-105 and miR-767 was indicative of poor prognosis. Functional pathway analysis identified target genes of miR-105 and miR-767 enriched in the phosphoinositide-3-kinase (PI3K) pathway, and analysis of over 200 cancer drugs in vitro showed that drugs targeting the same pathway had greater efficacy in cell lines with high miR-105 and miR-767 levels. Overexpression of the two miRNA facilitated response to PI3K inhibitor treatment. We demonstrate that while cancer is marked by considerable genetic heterogeneity, there is between-cancer concordance regarding the particular miRNA that are more variable. Bimodal miRNA are ideal biomarkers that can be used to stratify patients for prognosis and drug response in certain types of cancer.

Sprague Dawley (SD) rats are among the most widely used outbred laboratory rat populations. Despite this, the genetic characteristics of SD rats have not been clearly described, and SD rats are rarely used for experiments aimed at exploring genotype-phenotype relationships. In order to use SD rats to perform a genome-wide association study (GWAS), we collected behavioral data from 4,625 SD rats that were predominantly obtained from two commercial vendors, Charles River Laboratories and Harlan Sprague Dawley Inc. Using double-digest genotyping-by-sequencing (ddGBS), we obtained dense, high-quality genotypes at 291,438 SNPs across 4,061 rats. This genetic data allowed us to characterize the variation present in Charles River vs. Harlan SD rats. We found that the two populations are highly diverged (FST > 0.4). Furthermore, even for rats obtained from the same vendor, there was strong population structure across breeding facilities and even between rooms at the same facility. We performed multiple separate GWAS by fitting a linear mixed model that accounted for population structure and using meta-analysis to jointly analyze all cohorts. Our study examined Pavlovian conditioned approach (PavCA) behavior, which assesses the propensity for rats to attribute incentive salience to reward-associated cues. We identified 46 significant associations for the various metrics used to define PavCA. The surprising degree of population structure among SD rats from different sources has important implications for their use in both genetic and non-genetic studies.

Published: May 2022

Murine typhus, which is caused byRickettsia typhi, has a wide range of clinical manifestations. It has a low mortality rate but may result in meningoencephalitis and interstitial pneumonia in severe cases. Comparisons of complete genome sequences ofR.typhiisolates from North Carolina, USA (Wilmington), Myanmar (B9991PP), and Thailand (TH1527) identified only 26 single nucleotide polymorphism (SNP) and 7 insertion-deletion (INDEL) sites in these highly syntenic genomes. Assays were developed to further define the distribution of these variant sites among 15 additional isolates ofR.typhiwith different histories from Asia, the USA, and Africa. Mismatch amplification mutation assays (MAMA) were validated for 22 SNP sites, while the 7 INDEL sites were analyzed directly on agarose gels. Six SNP types, 9 INDEL types, 11 total types were identified among these 18 isolates. Replicate DNA samples as well as comparisons of isolates with different passage and source histories gave consistent genetic typing profiles. Comparison of the SNP and INDEL markers toR.typhi’snearest neighborRickettsia prowazekiidemonstrated that the majority of the SNPs represent intra-species variation that arose post divergence of these two species while several INDEL sites also exhibited intraspecies variability among theR.prowazekiigenomes that have been completely sequenced. The assays for the presence of these SNP and INDEL sites, particularly the latter, comprise a low technology gel method for consistently distinguishingR.typhi and R.prowazekiias well as for differentiating genetic types ofR.typhi.

Published: May 2022

Sickle cell disease (SCD) is an inherited blood disorder caused by a mutation in the HBB gene leading to hemoglobin S production and polymerization under hypoxia conditions leading to vaso-occlusion, chronic hemolysis, and progressive organ damage. This disease affects ~100,000 people in the United States and millions worldwide. An effective therapy for SCD is fetal hemoglobin (HbF) induction by pharmacologic agents such as hydroxyurea, the only Food and Drug Administration-approved drug for this purpose. Therefore, the goal of our study was to determine whether salubrinal (SAL), a selective protein phosphatase 1 inhibitor, induces HbF expression through the stress-signaling pathway by activation of p-eIF2α and ATF4 trans-activation in the γ-globin gene promoter. Sickle erythroid progenitors treated with 24μM SAL increased F-cells levels 1.4-fold (p = 0.021) and produced an 80% decrease in reactive oxygen species. Western blot analysis showed SAL enhanced HbF protein by 1.6-fold (p = 0.0441), along with dose-dependent increases of p-eIF2α and ATF4 levels. Subsequent treatment of SCD mice by a single intraperitoneal injection of SAL (5mg/kg) produced peak plasma concentrations at 6 hours. Chronic treatments of SCD mice with SAL mediated a 2.3-fold increase in F-cells (p = 0.0013) and decreased sickle erythrocytes supporting in vivo HbF induction.

Background

Perinatal mortality remains high globally and remains an important indicator of the quality of a health care system. To reduce this mortality, it is important to provide the recommended care during the perinatal period. We assessed the prevalence and factors associated with appropriate perinatal care (antenatal, intrapartum, and postpartum) in Bunyoro region, Uganda. Results from this study provide valuable information on the perinatal care services and highlight areas of improvement for better perinatal outcomes.

Methods

A cross sectional survey was conducted among postpartum mothers attending care at three district hospitals in Bunyoro. Following consent, a questionnaire was administered to capture the participants’ demographics and data on care received was extracted from their antenatal, labour, delivery, and postpartum records using a pre-tested structured tool. The care received by women was assessed against the standard protocol established by World Health Organization (WHO). Poisson regression with robust standard errors was used to assess factors associated with appropriate postpartum care.

Results

A total of 872 mothers receiving care at the participating hospitals between March and June 2020 were enrolled in the study. The mean age of the mothers was 25 years (SD = 5.95). None of the mothers received appropriate antenatal or intrapartum care, and only 3.8% of the participants received appropriate postpartum care. Factors significantly associated with appropriate postpartum care included mothers being >35 years of age (adjusted prevalence ratio [aPR] = 11.9, 95% confidence interval [CI] 2.8–51.4) and parity, with low parity (2–3) and multiparous (>3) mothers less likely to receive appropriate care than prime gravidas (aPR = 0.3, 95% CI 0.1–0.9 and aPR = 0.3, 95% CI 0.1–0.8 respectively).

Conclusions

Antenatal, intrapartum, and postpartum care received by mothers in this region remains below the standard recommended by WHO, and innovative strategies across the continuum of perinatal care need to be devised to prevent mortality among the mothers. The quality of care also needs to be balanced for all mothers irrespective of the age and parity.

Published: May 2022

Technology innovation has become an important driving force of economic and social development and has received wide attention from academics. Most scholars mainly take technology innovation as an overall variable to explore its impact on the economy and society. The main contribution of this study is to open the black box of technology innovation and introduce the lotka-Volterra model to explore the internal structure of technology innovation in the Chinese high-tech industry and to analyze the ecological relationships, evolutionary trends, equilibrium states of six technology innovation species including independent innovation (II), technology import (TI), research & development (RD), technology renovation (TR), foreign technology acquisition (FTA), and domestic technology purchase (DTP). The results of the study show that, First, the ecological relationship between prey and predator is observed between RD and TR, DTP and FTA, and II and TI. Second, no equilibrium state is observed between TD and TF and II and TI. Third, an unstable equilibrium state is observed between RD and TR.
Association of organizational and patient behaviors with physician well-being: A national survey in China
Authors: Wang Xiaoyu , Zhu Yimei , Wang Fang , Liang Yuan
Published: May 2022

This study aims to investigate the association of organizational and patient behaviors (reflecting the internal and external environment of hospital, respectively) with physician well-being. A national cross-sectional survey was conducted in 77 hospitals across seven provinces in China between July 2014 and April 2015. Physician well-being was assessed with job satisfaction, career regret and happiness. Organizational behaviors were assessed with organizational fairness, leadership attention and team interaction; patient behaviors were assessed with patient trust and unreasonable requests from patients. Of a study sample of 3,159 physicians, 1,788 were men (56.6%) and 1,371 were women (43.4%). Overall, positive organizational and patient behaviors reported by physicians were relatively low. Negative organizational behaviors and patient behaviors including lower organizational fairness, lower leadership attention, lower team interaction and lower patient trust were associated with lower job satisfaction and lower life satisfaction, and higher career regret. The association between organizational behaviors and physician well-being exhibited some gender differences, while no clear gender difference was found for the relationship between patient behaviors and physician well-being. Given the importance of physician well-being for the healthcare system, interventions for improving internal and external hospital environments (e.g., organizational fairness, leadership attention, team interaction and patient trust) may benefit physician well-being.
The principle of maximum entropy and the probability-weighted moments for estimating the parameters of the Kumaraswamy distribution
Authors: Helu Amal
Published: May 2022

Since Shannon’s formulation of the entropy theory in 1940 and Jaynes’ discovery of the principle of maximum entropy (POME) in 1950, entropy applications have proliferated across a wide range of different research areas including hydrological and environmental sciences. In addition to POME, the method of probability-weighted moments (PWM), was introduced and recommended as an alternative to classical moments. The PWM is thought to be less impacted by sampling variability and be more efficient at obtaining robust parameter estimates. To enhance the PWM, self-determined probability-weighted moments was introduced by (Haktanir 1997). In this article, we estimate the parameters of Kumaraswamy distribution using the previously mentioned methods. These methods are compared to two older methods, the maximum likelihood and the conventional method of moments techniques using Monte Carlo simulations. A numerical example based on real data is presented to illustrate the implementation of the proposed procedures.
Environmentally friendly, but behaviorally complex? A systematic review of e-scooter riders’ psychosocial risk features
Authors: Useche Sergio A. , Gonzalez-Marin Adela , Faus Mireia , Alonso Francisco
Published: May 2022

Introduction

E-scooters have made a place for themselves on urban roads as an affordable, easy-to-use and environmentally friendly method of transportation. However, and partly because of their road behaviors and safety outcomes, e-scooter users have started to represent a focus of attention for transport planners and policymakers.

Aim

The present systematic review aims to target and analyze the existing studies investigating the psychosocial characteristics of e-scooter riders, focusing on their behavioral and risk-related features.

Methods

For this systematic review, the PRISMA methodology was used, which allows for the selection of suitable papers based on the study topic, in accordance with a set of pre-defined criteria and a search algorithm. A total of 417 indexed articles were filtered, resulting in only 32 eligible original articles directly addressing the issue. WOS, Scopus, NCBI, Google Scholar, and APA databases were used to create and test search techniques.

Results

At the literature level, most of the existing studies are distributed in a few regions of the globe. At the user’s level, results show how e-scooters are most commonly used by young, highly educated, urban-dwelling males, usually for short trips. In regard to road behavior, individuals with the lowest degrees of risk perception remain more prone to engaging in risky road behaviors likely to increase their crash involvement. This might be worsened by the lack of normative e-scooter regulations (and their enforcement) in many countries, plus the marked absence of road training processes. As common limitations, it can be mentioned that 87.5% of these studies used self-report methods, while 59.4% had local coverage.

Conclusions

The findings of this systematic review endorse the growing need to develop and enforce traffic laws and training processes for e-scooter users. In addition, road safety education and training programs are highlighted by existing studies as potentially pertinent alternatives to increase risk perception, and reduce risky behaviors, road conflicts and crash likelihood among e-scooter riders.

Published: May 2022

Background

Several studies have demonstrated that helminth infections provide a degree of protection against Type 2 diabetes mellitus (T2DM). However, the relationship between Strongyloides stercoralis infection and T2DM has scarcely been investigated and the protective effect of infection against development of diabetic complications is unclear. In this study, we aimed to investigate the relationship between S. stercoralis infection and T2DM in a rural area of Khon Kaen Province, Thailand. The impact of S. stercoralis infection on diabetic complication-related kidney function biochemical parameters and body-mass index (BMI) was also assessed.

Methodology

Using a cross-sectional study design, S. stercoralis infection and T2DM assessments were conducted between October 2020 and May 2021. Associations between S. stercoralis infection, T2DM, and socioeconomic factors were analyzed using multivariable logistic regression analyses. Diabetic complication-related biochemical parameters relating largely to kidney function (estimated glomerular filtration rate (eGFR), urine albumin-to-creatinine ratio (UACR), serum creatinine, uric acid, alanine transaminase (ALT), and low-density lipoprotein cholesterol (LDL-C)) and BMI of participants with and without T2DM were compared between groups with or without S. stercoralis infection.

Results

One hundred and seven out of 704 individuals (15.20%) were positive for S. stercoralis, and 283 people were diagnosed with T2DM. Of those with T2DM, 11.31% (32/283) were infected with S. stercoralis and of those without T2DM, 17.82% (75/421) were infected with S. stercoralis. Multivariate analysis revealed that T2DM was inversely correlated with S. stercoralis infection (Adjusted OR  =  0.49; 95% CI: 0.30, 0.78; p  = 0.003), while male, increasing age, lower education level, and alcohol intake were positively associated with infection. Those infected with S. stercoralis had lower eGFR levels and higher ALT and UACR levels than those in the uninfected group.

Conclusion

This finding indicates that S. stercoralis infection was inversely associated with T2DM in northeastern Thailand, but participants infected with S. stercoralis had lower eGFR levels and higher ALT and UACR levels. Infection with S. stercoralis might lead to worse complication-related renal biochemical parameters.

Authors: Wang Luhong , Ding Yinan , Zhang Chuanyong , Chen Rong
Published: May 2022

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of the coronavirus disease (COVID-19), which poses a major threat to humans worldwide. With the continuous progress of the pandemic, a growing number of people are infected with SARS-CoV-2, including hepatocellular carcinoma (HCC) patients. However, the relationship between COVID-19 and HCC has not been fully elucidated. In order to provide better treatment for HCC patients infected with SARS-CoV-2, it’s urgently needed to identify common targets and find effective drugs for both. In our study, transcriptomic analysis was performed on both selected lung epithelial cell datasets of COVID-19 patients and the datasets of HCC patients to identify the synergistic effect of COVID-19 in HCC patients. What’s more, common differentially expressed genes were identified, and a protein-protein interactions network was designed. Then, hub genes and basic modules were detected based on the protein-protein interactions network. Next, functional analysis was performed using gene ontology terminology and the Kyoto Encyclopedia of Genes and Genomes pathway. Finally, protein-protein interactions revealed COVID-19 interaction with key proteins associated with HCC and further identified transcription factor (TF) genes and microRNAs (miRNA) with differentially expressed gene interactions and transcription factor activity. This study reveals that COVID-19 and HCC are closely linked at the molecular level and proposes drugs that may play an important role in HCC patients with COVID-19. More importantly, according to the results of our research, two critical drugs, Ilomastat and Palmatine, may be effective for HCC patients with COVID-19, which provides clinicians with a novel therapeutic idea when facing possible complications in HCC patients with COVID-19.

Authors: Bessho Rieko , Kashiwagi Kazuhiro , Ikura Akihiko , Yamataka Karin , Inaishi Jun , Takaishi Hiromasa , Kanai Takanori
Published: May 2022

Background

This cross-sectional study aims to investigate the association between subclinical atherosclerosis and metabolic dysfunction-associated fatty liver disease (MAFLD) or non-alcoholic fatty liver disease (NAFLD), and a synergistic effect of diabetes mellitus (DM) and MAFLD on subclinical atherosclerosis.

Methods

Of 977 subjects who underwent health checkups with coronary artery calcification (CAC), carotid intima-media thickness, and brachial-ankle pulse wave velocity (ba-PWV), 890 were included in this study. They were classified as MAFLD, NAFLD, or Neither-FLD, and MAFLD was further categorized into three groups by three metabolic disorders (obesity, lean with metabolic dysregulation, DM), according to its new definition: Obesity-MAFLD, Lean-MAFLD and DM-MAFLD.

Results

In a multivariable analysis, MAFLD and NAFLD were significantly associated with subclinical atherosclerosis, except for an association between ba-PWV and NAFLD. MAFLD had higher odds for CAC than NAFLD (for CAC score > 100, odds ratio (OR) = 2.599, 95% confidence interval (CI) = 1.625–4.157; OR = 1.795, 95%CI = 1.145–2.814, respectively). In a sub-analysis, DM-MAFLD had higher odds for CAC (for CAC score > 100, OR = 5.833, 95%CI = 3.047–11.164) than the other groups of MAFLD, when compared to Neither FLD as a reference. Moreover, DM-MAFLD had a higher level of homeostasis model assessment of insulin resistance and high sensitive C-reactive protein, compared to the other groups of MAFLD.

Conclusions

MAFLD was significantly associated with subclinical atherosclerosis in the general population. Additionally, DM-MAFLD could be a significant risk factor for cardiovascular disease through insulin resistance and low-grade inflammation and requires careful follow-up or appropriate intervention.

Published: May 2022

This study aimed to provide preliminary evidence for the efficacy of invasive laser acupuncture (ILA) for chronic non-specific low back pain (CNLBP). This was a single-center, randomized, patient and assessor-blinded, placebo-controlled, parallel-arm, clinical trial with a 1:1:1 allocation ratio that included a full analysis set. Forty-five participants with CNLBP were randomly assigned to the control group (sham laser), 650 group (650 nm-wavelength ILA), or 830 group (830 nm-wavelength ILA) (n = 15/group). All participants received ILA for 10 min, followed by electroacupuncture for 10 min on the same day. The treatment was performed once per day, twice per week for 4 weeks at bilateral BL23, BL24, BL25, and GB30. The primary outcome was the among-group difference of changes in the visual analog scale (VAS) scores at intervention endpoint (week 4). The secondary outcomes were the among-group difference of changes in VAS at 4 weeks after intervention completion (week 8), those in the Korean version of the Oswestry Disability Index (ODI) and the European Quality of Life Five-Dimension- Five-Level (EQ-5D-5L) at intervention endpoint (week 4) and 4 weeks after intervention completion (week 8). The VAS scores of the 650 group decreased significantly compared with those of the control group (p = 0.047; week 4 vs. week 0). The ODI scores of the 650 group (p = 0.018, week 4 vs. week 0; p = 0.006, week 8 vs. week 0) and 830 group (p = 0.014, week 4 vs. week 0) decreased significantly compared with those of the control group. There was no adverse event related to ILA and no significant difference in changes in vital signs among the three groups. The 650 group showed significant improvements in pain intensity and functional disability. The 830 group showed significant improvements in functional disability. Therefore, ILA therapy at 650 nm and 830 nm wavelengths can be used to treat CNLBP.

En los últimos años han ido emergiendo en YouTube divulgadores independientes de prácticamente la totalidad de campos académicos, culturales y científicos; también conocidos como influencers de ciencia. Paralelamente, las tradicionales instituciones académicas y científicas se han sumado al fenómeno de la divulgación digital lanzando sus propios canales de YouTube, como es el caso de las Unidades de Cultura Científica e Innovación (UCC+i) de la mayoría de universidades españolas. Este artículo profundiza en la divulgación científica desarrollada en YouTube por ambos colectivos y establece un análisis comparativo entre los resultados obtenidos por los influencers de ciencia frente a los canales institucionales. Los resultados revelan que los canales de YouTube que pertenecen a instituciones científicas tienen un alcance y un engagement muy por debajo del que poseen los canales de influencers de ciencia. En cuanto al estilo, los youtubers independientes apuestan por un formato audiovisual más adaptado a la plataforma y por el uso de un tono ameno basado en unos códigos comunes compartidos con la comunidad. Por su parte, los canales de entidades científicas muestran una faceta demasiado institucional y corporativa que seguramente esté lastrando su potencial divulgativo y su capacidad de impacto entre la ciudadanía mediática.
A tanulószervezet kontextus-adaptált modellje a magyar köznevelésben a pedagógusok munkahelyi elégedettségének függvényében
Authors: Horváth László
Published: May 2022

A tanulószervezet fogalma Senge 1990-ben megjelent könyvének köszönheti a népszerűségét és viszonylag hamar elterjedt az oktatási szervezetek kutatóinak körében is. Jelen tanulmány célja a tanulószervezet elméleti keretrendszerének megszilárdítása Garvin (2000) három kritériuma nyomán. Elsőként bemutatjuk a korábbi kutatásunk eredményeként megfogalmazott tanulószervezeti definíciót, majd a második kritérium keretében megvizsgáljuk egy nemzetközileg elterjedt tanulószervezeti mérőeszköz (Marsick és Watkins (2003) – Dimensions of the Learning Organisation Questionnaire (DLOQ)) adaptációját a magyar köznevelés mintáján. Végül bemutatjuk a tanulószervezet gyakorlati szempontból is hasznosítható összefüggéseit a munkavállalók munkahelyi elégedettsége alapján. Az elméleti feltáró munkánk eredményeként összegzett tanulószervezeti definíció összekapcsolja a szervezet- és vezetéselméleti, illetve neveléstudományi szempontokat, elhelyezi a tanulószervezet fogalmán belül a rokon elméleti modelleket (tudásmenedzsment, szervezeti tanulás, munkahelyi tanulás, változásmenedzsment). Az operatív definíciónk alapján a tanulószervezet egy komplex adaptív rendszer, amelynek vezetése, szervezeti struktúrája, kultúrája és emberi erőforrásai lehetővé teszik az adaptív viselkedésváltozást a tanulószervezeti viselkedés (tudásmenedzsment, munkahelyi és szervezeti tanulás, változásmenedzsment) folyamatainak működtetésével. A tanulmány keretében részletesen is kibontjuk a tanulószervezeti viselkedés fogalmát. Empirikus kutatásunk (online kérdőíves vizsgálat általános iskolai pedagógusok körében, N=1016) eredményei alapján a DLOQ megbízható (McDonald-féle omega) és érvényes (megerősítő faktoranalízis) mérőeszköznek tekinthető. Az összefüggésvizsgálatok keretében azonosítottuk azokat a tanulószervezeti dimenziókat, amelyek befolyásolják a munkavállalók általános munkahelyi elégedettségét (Hackman és Oldham (1973) munkasajátosságok modelljéből), illetve azt, hogy pozitív, semleges vagy negatív metaforával (szöveges válaszok tartalomelemzése alapján) illették-e az intézményüket. A tanulószervezeti viselkedés fejlesztésével az iskolák képesek megfelelni a tudásalapú társadalom kihívásainak, hiszen nem csak a tanulási eredményesség növelésében (pl. Mulford et al., 2004), hanem a munkavállalói elégedettség szempontjából is bizonyítható a jelentőségük.

Por fim, com os autores que nos ajudam a ir além dos limites da educação ambiental atual, apresentamos algumas proposições de como continuar nossa caminhada na produção de uma educação ambiental para a justiça ambiental junto, com e a partir dos próprios grupos e setores que vivem a desigualdade ambiental na região do sul do Brasil.
Hygrothermal Monitoring of Replacement Infill Panels for Historic Timber-Frame Buildings
Authors: Whitman Christopher , Prizeman Oriel , Walker Pete , Rhee-Duverne Soki , McCaig Iain
Published: May 2022

Energy retrofits aim to improve the thermal performance of buildings’ external envelopes. With buildings of traditional construction there exists the risk that these improvements may lead to interstitial condensation and moisture accumulation. For historic timber-framed buildings, this potentially exposes the embedded historic timbers to conditions favouring fungal decay and insect infestation. Hygrothermal digital simulations can assess this risk, however these have limitations, especially regarding the study of historic and traditional materials, due to a lack of accurate material data. The research presented in this paper therefore uses the monitoring of physical test panels to examine the performance of four different replacement infill details. These are, traditional wattle and daub, a composite of wood fibre and wood wool boards, expanded cork board, and hempcrete. The article focuses on the design and construction of the test cell and presents initial results from the first year of monitoring, following the initial drying phase. These showed no evidence of interstitial condensation in any of the panel build-ups, with increases in moisture content correlating directly with climatic measurements of wind-driven rain. Infill materials with low moisture permeability were seen to produce higher moisture contents at the interface with the external render due to the concentration of moisture at this point. Those panels finished in the more moisture permeable lime hemp plaster, overall present lower moisture contents, with reduced drying times. The use of perimeter, non-moisture permeable, sealants would appear to potentially trap moisture at the junction between infill and historic timber-frame. The monitoring work is ongoing.
El rizoma literario: lo performativo del sujeto
Authors: Zarta Rojas Fabian Andrey
Published: May 2022

La literatura transforma al sujeto porque tiene como materia prima la palabra y la imaginación, dos cuestiones que operan en el ser humano para su adecuado desarrollo de realidad. Al compartir estos elementos, se presenta lo que llamamos la conciencia bifurcada infinita, porque la función de la literatura es revelar mundos posibles. Se propone el pensamiento rizomático como método para evidenciar las complicidades y articulaciones posibles que ocurren entre literatura y performatividad. El presente artículo no intenta agotar el potencial analítico, sino dejar abierta la puerta para futuras exploraciones, reflexiones o textos. En general, en la literatura, durante el siglo XXI, se descubre el papel de lo performativo en el sujeto y su incidencia en lo político. El activismo propio del mundo de hoy, en su versión tanto presencial como virtual (redes sociales), nos indica la estrecha relación entre lo estético (incluida la literatura y la ficción) y lo político.
