Introduction: Transcranial magnetic resonance-guided focused ultrasound surgery (TcMRgFUS) has the advantage of allowing immediate evaluation of therapeutic effects after each sonication and intraoperative magnetic resonance imaging (MRI) to visualize the lesion. When the image shows that the lesion has missed the planned target and the therapeutic effects are insufficient, the target of the subsequent ablation can be finely adjusted based on the image. The precision of this adjustment is determined by the image quality. However, the current intraoperative image quality with a 3.0T MRI system is insufficient for precisely detecting the lesion. Thus, we developed and validated a method for improving intraoperative image quality. Methods: Because intraoperative image quality is affected by transmitter gain (TG), we acquired T2-weighted images (T2WIs) with two types of TG: the automatically adjusted TG (auto TG) and the manually adjusted TG (manual TG). To evaluate the character of images with 2 TGs, the actual flip angle (FA), the image uniformity, and the signal-to-noise ratio (SNR) were measured using a phantom. Then, to assess the quality of intraoperative images, T2WIs with both TGs were acquired during TcMRgFUS for 5 patients. The contrast-to-noise ratio (CNR) of the lesion was retrospectively estimated. Results: The images of the phantom with the auto TG showed substantial variations between the preset and actual FAs (p < 0.01), whereas on the images with the manual TG, there were no variations between the two FAs (p > 0.05). The total image uniformity was considerably lower with the manual TG than with the auto TG (p < 0.01), indicating that the image’s signal values with the manual TG were more uniform. The manual TG produced significantly higher SNRs than the auto TG (p < 0.01). In the clinical study, the lesions were clearly detected in intraoperative images with the manual TG, but they were difficult to identify in images with the auto TG. The CNR of lesions in images with manual TG was considerably higher than in images with auto TG (p < 0.01). Conclusion: Regarding intraoperative T2WIs using a 3.0T MRI system during TcMRgFUS, the manual TG method improved image quality and delineated the ablative lesion more clearly than the current method with auto TG.

Published: July 2023

Background: Despite a growing number of tracheobronchial stent types and indications, complications remain frequent, and high-quality evidence on practices to prevent stent-related complications is lacking. Understanding current management practice is a first step to designing prospective studies to assess whether specific practices aimed at mitigating stent-related complications improve patient-centered outcomes. Objectives: In this study, we aimed to understand current management strategies following tracheobronchial stenting. Method: We performed a nationwide survey of members of the American Association of Bronchology and Interventional Pulmonology (AABIP) and the General Thoracic Surgical Club (GTSC) who place airway stents. The electronic survey captured data on practitioners’ demographics, practice setting, airway stent volume, and standard post-stent practices (if any) including the use of medications, mucus clearance devices, surveillance imaging, and surveillance bronchoscopy. Results: One hundred thirty-eight physicians completed the survey. Respondents were majority male (75.4%) and had diverse training (50.0% completed interventional pulmonary fellowship; 18.1% thoracic surgery; 31.9% other stent training). Post-stent management strategies varied markedly across respondents; 75.4% prescribe at least one medication to prevent post-stent complications, 52.9% perform routine surveillance bronchoscopy in asymptomatic patients, 26.1% prescribe mucus clearance regimens, 16.7% obtain routine computed tomography scans in asymptomatic patients, and 8.3% routinely replace their stents prior to stent failure. Conclusions: In this national survey of practitioners who place airway stents, there was marked heterogeneity in post-stent management approaches. Further studies are needed to identify which, if any, of these strategies improve patient-centered outcomes.

Published: July 2023

BACKGROUND:

Although blood pressure (BP) increases throughout young adulthood for most individuals, the age-related slope is not uniform. This study aimed to assess associations of demographic, clinical, behavioral, psychosocial, and neighborhood characteristics with age-related BP slope among 4 race-sex groups who participated in the Coronary Artery Risk Development in Young Adults study.

METHODS:

Individuals (n=3554) aged 18 to 30 years were included in this analysis if they had normal BP at baseline and ≥2 BP measurements during the years 1985/1986 to 2015/2016. Associations of exposure variables with systolic BP slope were assessed using multivariate linear models.

RESULTS:

Over a mean follow-up of ~30 years, greater decade increases in systolic BP were estimated among Black than White participants (mean difference between Black females and White females: 3.0 mm Hg/decade; between Black males and White males: 4.7 mm Hg/decade). The exposure risk factors associated with greater increases in systolic BP throughout adulthood varied by race and sex. None of these factors were associated with increases in systolic BP in all race-sex groups. Parent history of high BP was associated with a steeper positive slope among Black females (effect size per decade: 1.1 [95% CI, 0.6–1.6];
P
<0.01), Black males (0.6 [95% CI, 0.02–1.2];
P
<0.05), and White females (0.6 [95% CI, 0.2–1.0];
P
<0.01). Other risk factors were associated with greater age-related yearly increases in systolic BP among 1 or 2 of the 4 race-sex groups or were not statistically significant.

CONCLUSIONS:

Culturally tailored BP reduction approach should be considered in conjunction with primordial prevention, to moderate increases in BP throughout adulthood.
Triple motif proteins 19 and 38 correlated with treatment responses and HBsAg clearance in HBeAg-negative chronic hepatitis B patients during peg-IFN-α therapy

Published: July 2023

Objective

To investigate whether the expression of triple motif protein 19/38 (TRIM19/38) mRNA in peripheral blood mononuclear cells (PBMCs) of HBeAg-negative chronic hepatitis B virus (HBV) carriers is associated with the response to pegylated interferon alpha (peg-IFN-α) treatment and HBsAg clearance.

Methods

In this prospective study, HBeAg-negative chronic HBV carriers treated with peg-IFN-α completed 48 weeks of follow-up. After treatment with peg-IFN-α, the patients were divided into responders (R group) and nonresponders (NR group) according to the changes in HBV DNA and HBsAg levels at week 48 of treatment. According to whether serum HBsAg loss or seroconversion occurred, the patients were divided into a serological response group (SR group) and a nonserological response group (NSR group). The level of TRIM19/38 mRNA in PBMCs was detected by real-time fluorescence quantitative PCR. The diagnostic performance of TRIM19/38 was analysed by calculating the receiver operating characteristic (ROC) curve and area under the ROC curve (AUC).

Results

43 HBeAg-negative chronic HBV carriers, 35 untreated CHB patients and 19 healthy controls were enrolled in this study. We found that TRIM19/38 mRNA levels were significantly lower in untreated CHB patients than in healthy controls. In HBeAg-negative chronic HBV carriers who underwent prospective follow-up, TRIM19/38 mRNA levels were negatively correlated with HBV DNA and ALT at baseline. Among the patients treated with peg-IFN-α, 16 patients achieved a treatment response (R group) and 27 patients did not achieve a treatment response (NR group). Compared with baseline, HBsAg levels in the R group decreased significantly at 12 and 24 weeks of treatment; at the early stage of peg-IFN-α treatment, the dynamic changes in TRIM19/38 mRNA levels in the R and NR groups were different, and the TRIM19/38 mRNA levels in the R group were significantly higher than those in the NR group, especially at 24 weeks of treatment. ROC curve analysis showed that the changes in mRNA levels of TRIM19 and TRIM38 predicted the treatment response, with AUCs of 0.694 and 0.757, respectively. Among the patients treated with peg-IFN-α, 11 patients achieved a serological response (SR group) and 32 patients did not achieve a serological response (NSR group). Compared with baseline, HBsAg levels in the SR group decreased significantly at 12 and 24 weeks of treatment; TRIM19/38 mRNA levels were significantly higher in the SR group than in the NSR group at week 24.

Conclusion

The higher level of TRIM19/38 mRNA in PBMCs of HBeAg-negative chronic HBV carriers may be related to the early treatment effect of peg-IFN-α and HBsAg clearance. TRIM19 and TRIM38 have clinical significance in predicting virological response and guiding treatment regimens.
Anorexia nervosa and the COVID-19 pandemic among young people: a scoping review
Authors: Schlissel Anna C. , Richmond Tracy K. , Eliasziw Misha , Leonberg Kristin , Skeer Margie R.
Published: July 2023

Background

The extent to which the recent global COVID-19 Pandemic has impacted young people with restrictive eating disorders [i.e., anorexia nervosa (AN) and atypical anorexia nervosa (AAN)] is unclear. We conducted a scoping review of the literature to identify how the pandemic has impacted this population and to identify gaps in the current literature to inform future research efforts.

Main body

We searched PubMed, EMBASE, the Web of Science, The Cochrane Library, PsycInfo, ProQuest Dissertations and Theses Global, LitCovid, Google Scholar, and relevant agency websites from 2019 to 2022. We included studies that focused on young people with AN/AAN globally. Of the 916 unduplicated articles screened, 17 articles met the inclusion criteria, reporting on 17 unique studies including 4,379 individuals. Three key findings were identified. First, an increase in hospitalizations related to eating disorders was found during COVID-19 among young people with AN and AAN. Multiple studies cited increased medical instability, even though the overall duration of disease was shorter compared to pre-pandemic levels. Second, changes in eating disorder-related symptomology during the pandemic were reported in this population, as well as poorer overall behavioral and mental health. Suggested reasons behind changes included boredom or minimal distraction from pathological thoughts, increased social isolation, increased social media and online use (e.g., reading blogs or watching YouTube), gym and school closures, changes in routines due to lockdowns and quarantines, and worries over gaining the “Quarantine 15”. Third, there was an increase in the use of telemedicine as a treatment modality for the treatment of AN. Challenges were reported by both clinicians and patients regardless of past experience using telemedicine. When compared to no treatment, telemedicine was recognized as the best option during COVID-19 lockdowns; however some individuals expressed the preference for in-person treatment and planned to return to it once it became available.

Conclusion

The pandemic significantly impacted young people with restrictive eating disorders as seen by increased hospitalizations and requests for outpatient care. A primary driver of the changes in eating disorder symptomatology may be lockdowns and quarantines. Further research investigating how the series of lockdowns and re-openings impacted individuals with AN/AAN is warranted.

This book focuses on the understudied topic of long-term (over five years) survivors of intimate partner violence and abuse (IPV/A) and the resiliency they experience as they negotiate life after (physical) separation from abusive partners. Drawing on participant observation research and semi-structured interviews with women years after relationship termination, the study informs us about their trials and tribulations and the factors facilitating their success on the road to survivorship, which can involve gaining inner strength, personal transformation, and crucial help from individuals and social institutions. Through a sociological lens, the women’s life experiences are explored in a theoretical framework that draws upon trauma, identity construction, the notions of victim and survivor, resiliency, agency, and meaning making. Based on the analysis of common themes that run through the narratives of long-term survivors of IPV/A, the book also offers practical recommendations for improving the lives of abused women and the responses to them by social service agencies and justice institutions. The book is useful for university students, and it will inform criminal justice and social service professionals, policy makers, and inspire others who are victims/survivors of IPV/A.
Integrative Nursing and the ANA Scope and Standards of Practice: Expanding the Reach of Nursing for Families and Society
Authors: Jo Kreitzer Mary , Koithan Mary , Sullivan Shanna D. , Nunez Molly , Voss Megan
Published: July 2023

The American Nurses Association's (ANA) recently published 4th edition of the Scope and Standards of Practice provides authoritative guidance on actions and behaviors that all registered nurses are expected to perform competently, regardless of role, population, specialty, or setting. The newly defined scope emphasizes the art and science of caring, compassionate presence, and the expectation that nurses be advocates for all, recognizing the connections of all humanity. It also makes frequent reference to whole-person care and highlights the importance of mindfulness by inviting nurses to refect on how they can incorporate mindfulness and other integrative therapies into their self-care and professional practice. A new standard explicitly states that advanced practice registered nurses should have the competency to prescribe evidence-based traditional and integrative treatments, therapies, and procedures that are compatible with the consumer's cultural preferences, norms, and abilities. Integrative Nursing is aligned with the ANA Scope and Standards of Practice and provides a useful framework for practice that expands the reach of nursing across clinical and community settings and patient populations. In this article, exemplars highlight how Integrative Nursing is being implemented in clinical settings and nursing education programs.

Published: July 2023

Abstract: As mobile phone technology advances, the device looks to be capable of contributing to student learning and increased academic achievement. The recent fast growth in cell phone use has had an impact on many facets of our everyday lives, especially those of students. As a result, the current study attempts to investigate the impact of mobile phone usage on academic performance among male and female students in the Nandurbar area. A face-to-face survey was done among 274 students, 159 male students and 115 female students ranging from second to fourth year from various college departments. Gender, age, and connection with opposite sex have a considerable favourable influence on pupils' academic achievement, according to the findings. However, marital status, mobile phone usage, and the detrimental effect of mobile phone and application usage while studying all have a negative influence on students' academic performance. Cell phones are indisputably convenient and useful study aids, but they may also be a harmful source of distraction depending on a student's mindset and use behaviour. The author, on the other hand, proposes that mobile phone manufacturers consider how young people utilise cell phones for educational reasons.
Chiral superconductivity in the doped triangular-lattice Fermi-Hubbard model in two dimensions
Authors: Zampronio Vinicius , Macrì Tommaso
Published: July 2023

The triangular-lattice Fermi-Hubbard model has been extensively investigated in the literature due to its connection to chiral spin states and unconventional superconductivity. Previous simulations of the ground state of the doped system rely on quasi-one-dimensional lattices where true long-range order is forbidden. Here we simulate two-dimensional and quasi-one-dimensional triangular lattices using state-of-the-art Auxiliary-Field Quantum Monte Carlo. Upon doping a non-magnetic chiral spin state, we observe evidence of chiral superconductivity supported by long-range order in Cooper-pair correlation and a finite value of the chiral order parameter. With this aim, we first locate the transition from the metallic to the non-magnetic insulating phase and the onset of magnetic order. Our results pave the way towards a better understanding of strongly correlated lattice systems with magnetic frustration.
Pollen morphology of Brazilian Aristolochia subgenera Aristolochia (Aristolochiaceae) and its taxonomical significance
Authors: Freitas Joelcio , Santos Francisco de Assis Ribeiro dos , Alves-Araújo Anderson
Published: July 2023

Aristolochia (Aristolochiaceae) comprises about 550 species and
especially in the Neotropical region where this genus is highly diverse
few studies of palynological characterization have been conducted. To
better understand the pollen morphology of the genus, pollen grains of
25 species were examined, of which one belongs to Aristolochia
subgenus Siphisia and 24 to Aristolochia subgenus
Aristolochia (three of Aristolochia series
Thyrsicae; eight of Aristolochia series Hexandrae
subser. Anthocaulicae, and 13 of Aristolochia series
Hexandrae subseries Hexandrae). Pollen grains are radially
symmetrical, apolar, inaperturate and spheroidal. Under SEM,
ornamentation patterns of the exine are fossulate (19 species),
fossulate-areolate (four species), microfossulate (one species) and
verrucate (one species). Most species have pollen with perforated
surface except A. gibertii, A. holostylis, A.
pohliana, and A. ridicula. Results corroborate that the
micromorphological features, such as pollen shape and aperture absence
are similar in all species of Aristolochia, but for some species
exine ornamentation might be useful for taxonomic distinction at the
species level.
Polish Humanitarian Aid and Military Assistance to Ukraine Fighting Russia
Authors: Bąk Tomasz
Published: July 2023

The article describes the aid Poland is providing to Ukraine fighting Russia. Our country has been providing both humanitarian and military assistance since the beginning of Russia’s conflict with Ukraine, i.e. from 24 February 2022 up till now. Poland is a country that is at the forefront of contributing such help. Special attention should be paid to the involvement of Polish society, especially in the first days of the war, where they received Ukrainian refugees in their own homes sharing food and money with them. Military assistance, which has been continuously sent to the Ukrainian army for two years, plays an important role, and our Armed Forces are involved in the training of Ukrainian soldiers. Without international support, Russia’s flag would have already been hoisted on the tallest buildings in Kiev, and someone appointed by Vladimir Putin would have taken the presidential seat in place of Volodymyr Zelenskyy.

Published: July 2023

Background

The World Health Organization’s call for elimination of cervical cancer envisages 70% screening coverage of women aged 35 and 45 years by an effective test. In India, this target seems unrealistic as awareness and access to cancer prevention services are poor. However, the institutional delivery rate is now >80%. We evaluated the acceptability and feasibility of human papillomavirus (HPV) testing and its role in screening during pregnancy.

Methods

This observational study recruited 275 pregnant women aged >25 years between 12 and 34 weeks of gestation for screening by cytology and HPV testing. Colposcopy was advised if either test was positive. Acceptability and feasibility were assessed by a questionnaire.

Results

Cytology and HPV reports were available for 269 subjects. The median age was 28 years and median parity was two. Only 98 (36.4%) had heard about carcinoma cervix. Awareness improved with education (p<0.001). On cytology, only 4 (1.5%) were abnormal (atypical squamous cells of undetermined significance 3; low-grade squamous intraepithelial lesion 1). The prevalence of high-risk HPV infection was 8.2% (22/269). On colposcopy, all had the Swede score <5. No high-grade cervical intraepithelial neoplasia or carcinoma was detected. Pre-procedure, 183 (68.0%) subjects expressed apprehension, post-procedure 114 (42.4%) of them had realized that their apprehensions were unfounded. Women found screening to be more uncomfortable after 28 weeks of gestation (n=26/68; 38.2%; p<0.001). Physicians found the cervix more difficult to visualize after 20 weeks of gestation (p<0.001).

Conclusions

HPV screening at 16–20 weeks of pregnancy is acceptable, feasible, and can greatly improve screening coverage in resource-limited settings. Pregnancy is a good opportunity to improve awareness of the screening programmes.

Along the decline COVID-19 cases in Indonesia, the implementation of Limited Face-to-face Learning (PTM) in education units was again carried out by observing the implementation of strict health protocols by education units. In the implementation, various problems were found, such as the lack of awareness of students in implementing health protocols. The solutions offered by the Community Service team to support preventing the spread of COVID-19 and improving healthy lifestyles include developing a health protocol ambassador program through a peer teaching program with the Montessori method. This activity was carried on August 8, 2022 with assistance and monitoring carried out until August 22, 2022 at SD Muhammadiyah 01 Medan with a total sample of 60 people. The results showed an increase before and after the activity, before the activity was carried out as many as 31 (51.7%) respondents were at a moderate level of knowledge, 37 (61.7%) positive attitudes and 32 (53.3%) good behavior respondents. After the activities were carried out, 47 (78.3%) respondents had high knowledge, 60 (100%) positive attitudes and 46 (76.7%) good behavior. Therefore, this method is effective in increasing the knowledge, attitudes and behavior of students' awareness about health protocols and prevention of COVID-19 transmission.

The scarcity of fertilizers in Indonesia makes it difficult for farmers to find alternative fertilizers, the causes are subsidized fertilizers which are difficult to obtain, and the high cost of non-subsidized fertilizers making it burdensome for farmers. Most of the community professionals in Sungai Ular Village are farmers and the lack of availability of fertilizers and the heavy economic value of inorganic fertilizers. Based on the potential of Sungai Ular Village, Secanggang District, the raw materials for making organic fertilizer can utilize Hydrilla verticillata plants, livestock faeces and rice straw. The organic fertilizer produced can be used for traditional cultivation. The results of this community service activity, in addition to ready-to-use organic fertilizers, are horticultural crops such as kale, spinach, curly red chillies, tomatoes, basil, etc. The resulting horticultural crops are expected to increase partner agricultural yields which can increase income and support the entrepreneurial spirit of partners in optimally utilizing village potential. Community Service Activities can empower the community to realise independence and prosperity and maintain environmental sustainability by reducing the use of inorganic fertilizers (chemical fertilizers) by optimally utilizing the potential of Sungai Ular Village, Secanggang District, Langkat Regency.

A crucial asset in the management of invasive species is the open-access sharing of data on the range of invaders and the progression of their spread. Such data should be current, comprehensive, consistent and standardised, to support reproducible and comparable forecasting efforts amongst multiple researchers and managers. Here, we present the lydemapr R package containing spatiotemporal data and mapping functions to visualise the current spread of the spotted lanternfly (Lycorma delicatula, White 1841) in the Western Hemisphere. The spotted lanternfly is a forest and agricultural pest in the eastern Mid-Atlantic Region of the U.S., where it was first discovered in 2014. As of 2023, it has been found in 14 states according to State and Federal Departments of Agriculture. However, the lack of easily accessible, fine-scale data on its spread hampers research and management efforts. We obtained multiple memoranda-of-understanding from several agencies and citizen-science projects, gaining access to their internal data on spotted lanternfly point observations. We then cleaned, harmonised, anonymised and combined the individual data sources into a single comprehensive dataset. The resulting dataset contains spatial data gridded at the 1 km2 resolution, with yearly information on the presence/absence of spotted lanternflies, establishment status and population density across 658,390 observations. The lydemapr package will aid researchers, managers and the public in their understanding, modelling and managing of the spread of this invasive pest.
Preservice Teacher Curricula Should Include Research on Non-Cognitive Characteristics
Authors:   Wilkes University, Jones Victoria A.
Published: July 2023

Institutions of higher education need to provide curricula for preservice teachers on the importance of non-cognitive characteristics related to success to best prepare and maintain new teachers in K-12 schools throughout the country. Many educators of preservice teachers experienced the importance of curricula that psychologically and emotionally prepares future educators for crippling events, before, during, and after the onset of the coronavirus pandemic. Crises of all types are inevitable within society and schools, and how they are handled by educators will vary based upon educators’ non-cognitive characteristics. While societal upheaval can negatively impact schools, faculty, and students by adding stress and uncertainty to the day-to-day work of educators, coping mechanisms such as resilience, grit and self-efficacy can prevent consequences such as teacher burnout and attrition. Consequently, preservice teachers will benefit by accumulating knowledge about the power and importance of these types of non-cognitive characteristics before they enter the field.

Authors:   Villanova University, Souteer Madora , Timmerman Joanna ,   Eastern University
Published: July 2023

Transformative social and emotional learning (Jagers et al., 2019), a form of socialemotional learning (SEL) specifically focused on equity, is an important part of student overall well-being and success. However, there is limited research on how to effectively prepare teachers to bring SEL to their classrooms, especially SEL grounded in social justice. In order to contribute to the growing field of teacher training in social-emotional learning, this qualitative study explores teacher perceptions of their own preparedness in this area. Findings reveal that teachers saw their own transformative SEL as a key factor in supporting students’ transformative SEL, highlighting the importance of holistic teacher preparation that focuses on the social-emotional development of teachers themselves.

The role of the preservice teacher, during the final semester of the collegiate journey, has typically consisted of a fixed amount of time spent in one classroom as an opportunity to learn the day-to-day operations. This includes lesson planning, classroom management, and all other duties of the assigned teacher. Factor in a global pandemic, and the process shifts. In this study, the researchers present a new dynamic to the preservice teacher experience – serving as a paraprofessional. This qualitative analysis provides a snapshot of four preservice teachers’ experiences in this newly developed dual role of student teacher and paraprofessional during a pandemic.
Interactions and Gains in Cultural Responsiveness in Pre-Service Educators
Authors:   Messiah University, Burchard Melinda
Published: July 2023

All teachers, special educators included, need to build competencies to honor and respond to the cultures of the students in their classrooms and school communities. This study of 64 pre-service teachers investigated interactions between their culturally responsive experiences specific to teaching children with disabilities and their self-efficacy for culturally responsive teaching of diverse children who qualify for special education. Participants self-rated their experiences and self-efficacy using the Culturally Responsive Special Education Experiences and Efficacy Scale which worked as a measure of self-efficacy. Variance in culturally responsive experiences explained nearly half of the variance in culturally responsive self-efficacy. Participants made very large effect size gains in both culturally responsive experiences and culturally responsive self-efficacy, though post-assessment self-efficacy remained merely moderate, indicating a next step for program improvement to increase culturally responsive experiences.

As part of one predominantly White institution’s efforts to better support teacher candidates of Color (TCOCs), researchers held focus group discussions with TCOCs. Findings include TCOCs’ diverse identities and shared experiences of “onlyness” in educational settings (Harper et al., 2011). Recommendations include racial affinity groups and highlighting teacher diversity in curricula. This work was supported by the McElhattan Foundation.
Digital Humanities as Inclusive Knowledge Translation: a Multi-Phase Qualitative Pilot Study
Authors: Hu John C H.
Published: July 2023

Knowledge translation (KT), the dissemination of research outputs towards utilization and application, is increasingly recognized in research. For marginalized populations, benefiting from research outputs can be hindered by longstanding, inequitable access to information and education. The objective of this pilot study is to assess the potential of using creative works in the digital humanities - such as films, series, animations, games, and graphic novels - as knowledge translation tools for engagement, inclusivity, and equitable access to research-based knowledge. Methods followed a multi-phase process. First, an exploratory literature review was conducted on the intersection between three pillars: digital humanities, marginalized populations, and knowledge translation (Web of Science and Scopus), with 21 studies that met the inclusion criteria. Operational definitions and project framework (CATER) were drawn from the gap analysis, followed by a first round of pilot interviews with individuals with qualitative research experience. The first pilot interviews were conducted to identify any conceptualization errors and address methodological concerns. The second round of pilot interviews was conducted with marginalized individuals. Research findings show that marginalized populations access digital humanities for self-motivated learning. The implications of this research suggest digital humanities can serve as KT tools to supplement existing modes of KT, and that further participatory research will help uncover complex relationships between digital humanities and living with marginalization.
Production of unsaturated fatty acids (omega 3,6,7,9) from algae Lyngbya and Oedogonium under the influence of nitrogen and phosphorus

Microalgae have a lot of promise for making nutritious food and feed additives. These photosynthetic show promise for the longterm production of lipids due to their capacity to transform carbon into high-value chemicals and their ability to be grown on a vast scale without interfering with crop cultivation. Particularly, microalgae serve as a substitute source of unsaturated fatty acids (UFAs), whose consumption is linked to a number of advantages for both human and animal health. The generation of PUFAs in microalgae has been improved in recent years through the investigation of several methods. Two algae were isolated from the Gharaf river in Thi-Qar (Oedogonium, Lyngbya). The study was conducted on the effect of different concentrations of nitrogen and phosphorus for each of the unsaturated fatty acids of the two algae. Nitrogen concentrations were (5,10,20) and for phosphorus (1,5,10). These (UFAs) are affected when these nutrients are added to the culture medium, and as the concentration of these nutrients increases, we notice a decrease in the proportions of these unsaturated fatty acids (Octadecatrienoic acid, omega 6, Oleic acid omega 9, Eicosapentanoic acid omega 3, Docosatetraenoic acid omega 3) in Lyngbya and with absence OA, Docosatetraenoic acid and presence (vaccenic acid, omega 7) in Oedogonium.

Published: July 2023

This study focuses on the preparation and characterization of nanocrystalline Fe-A (Ni, Co, and Si) alloy powders using mechanical alloying technique with Retsch PM 400 high energy planetary ball mill. The evolution of the phases and magnetic properties of the powders are investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and vibrating sample magnetometer (VSM) as a function of grinding time. The XRD results indicate that after 20 hours of milling, the FeNi, FeCo, and FeSi phases are completely formed. The lattice deformation of FeSi alloy is 0.7%, and the grain size decreases to 17 nm, 13.5 nm, and 10 nm for FeNi, FeCo, and FeSi, respectively. SEM observations of the powder morphologies at different stages of alloy formation are also conducted. Moreover, elemental maps of Fe, Ni, Co, and Si obtained by EDS experiments confirme the XRD results on the evolution of the alloy formation. Finally, the VSM results showed that the magnetic properties of FeNi, FeCo, and  FeSi alloy nanoparticles are influenced by the composition, size, and morphology of the particles. Overall, this study provides valuable insights into the preparation and characterization of nanocrystalline Fe-A (Ni, Co, and Si) alloy powders, which may have potential applications in various fields.
